The present invention provides for an improved exercise resistance system to conduct numerous total body exercises.
An adjustable elastic resistance cord or flat band may be combined with weights, or each type of resistance may be used alone, in order to vary the means of creating resistance during exercise.
The length of the elastic resistance cord or flat band may be adjusted by means of a slip free, length quick adjustment device.
The elastic resistance cord or flat band may be passed through the length quick adjustment device which may be secured at various points along the length of the elastic resistance cord or flat band, to change its effective usable length and thus change the level of strength, and range of motion.
The length quick adjustment device may be secured by pulling an elastic resistance cord or flat band in one direction, and released by pulling the elastic resistance cord or flat band in the opposite direction..
One end of the elastic resistance cord or flat band is attached to any hand engagement structure, preferably a cord handle/grip, a dumbbell handle/grip, a bar, or a glove.
The other end of the elastic resistance cord or flat band is secured to any anchor structure, preferably a movable structure, such as a flat board, pad, aerobic step, workout bench, or TV interactive exercise structure..
BACKGROUND OF THE INVENTION  Exercise equipment may provide resistance against muscle movement by a user through various means.
The force of gravity provides resistance to users of free weights such as ankle weights, wrist weights, weight vests, dumbbells, and barbells.
Free weights may be created by incorporating various forms of metal, water or sand.
Some types of exercise equipment also utilize the force of gravity to provide resistance through the transfer of force through cables to weights positioned with the apparatus.
Other types of resistance may be created through the use of hydraulic cylinders, springs, and flexible rods.
Resistance may also be created with the use of a pressure screw in conjunction with a friction brake.
A user's own body weight may provide the necessary resistance to conduct exercise..
Equipment may also utilize elastic resistance cords or flat bands, which stretch and elongate under pressure, to provide the necessary resistance to a user when conducting exercises.
Elastic resistance cords or flat bands may be hand held or incorporated into a machine and may be closed loop or open elastic resistance cords or flat bands.
Elastic resistance cords and flat bands provide an advantage through ease of use in that they are lightweight, compact, and inexpensive.
Additionally, elastic resistance cords and flat bands provide increasing resistance as they stretch through a range of motion..
Another popular and common type of resistance exercise utilizes hand weights, such as dumbbells, barbells, weighted bars, and kettle bells.
Another popular type utilizes tubular elastic resistance cords or flat bands.
Each type of resistance (weights or elastic resistance cords or flat bands) provides a distinct and beneficial form of resistance exercise.
However, each form has limitations.
Free weights are generally more expensive, heavy, bulky, and non compact.
Due to their heavy and bulky nature, weights alone are not very portable or easy to store.
Further, adjusting the level of resistance by adding weights or changing to different weights is often time consuming and difficult.
Additionally, adjusting a user's range of motion when utilizing weights is often difficult..
Elastic resistance cords or flat bands also have limitations.
The predominant form of elastic resistance in the prior art is an elastic cord of a fixed length with handles attached at each end.
Elastic resistance cords and flat bands are limited because they are generally of a uniform length and strength.
Elastic resistance cords and flat bands of different strengths are generally manufactured to be distinguished by different colors or numbers.
In order to change the resistance obtained while performing exercises, a user has traditionally been required to purchase an elastic resistance cord or flat band of a different strength or add more than one cord or flat band to a handle.
This process is time consuming and expensive.
Also, elastic resistance cords or flat bands usually come in a fixed length.
Thus, elastic resistance cords or flat bands are limited, in that a user cannot easily adjust the strength of resistance or the range of motion..
The limitations in the current state of the art utilizing resistance bands are easily seen in products currently in the marketplace.
A product currently being sold under the trademark Reebok™ utilizes a resistance cord, secured by handles at each end, to provide resistance.
The resistance cord is attached to the handle by wrapping the resistance cord around posts on the handle.
A user may then attempt exercise by pulling on the handle against the resistance of the resistance cord.
However, the means of attaching the resistance cords to the handle and adjusting the resistance cords (a post) has clear limitations in that the resistance cords are not firmly secured to the handle, and the resistance cords easily become dislodged from the handle post.
The inability to adequately secure the resistance cord to the handle not only reduces the effectiveness of the workout, but also creates a potential safety hazard if the cord should inadvertently dislodge from the handle in a workout..
Similarly, U.S. Pat.
No. 5,894,631 describes a handle capable of engaging a resistance member, such as an elastic cord, by passing the resilient member through a tapered passage in the handle and securing the resilient member by engaging it with a spherical member also positioned within the tapered passage.
However, the spherical member is loosely situated within the tapered passage and capable of complete removal from the tapered passage.
Further, the tapered passage is conically shaped which permits the spherical member to easily dislodge from the tapered passage.
Even with the spherical member in place in the tapered passage, the spherical member is easily dislodged thereby reducing its effectiveness in securing the resilient member.
Additionally, resistance is derived only by pulling two handles in opposite directions, and does not contain a means to attach the resistance bands to another structure thus limiting the number and types of exercises that may be performed..
Further, an exercise system by Thera-Band® consists of a fitness ball platform to which resistance cords may be attached.
However, the platform is large and bulky preventing a user from easily transporting the exercise system.
Further, the platform contains a depressed surface to accommodate an exercise ball which requires the addition of additional elements to make a flat useable surface.
The depressed surface does not create an evenly flat surface thus increasing the risk that the user will sustain an ankle injury when stepping onto the surface of the platform..
The present invention overcomes the limitations of the prior art by providing for a combination of various types of exercise resistance including but not limited to a combination of weights, gyroscopes, magnetic resistance, ropes, cables, wires, pneumatic resistance, hydraulic resistance, friction brake resistance, or the weight of a user's own body with elastic resistance cords or flat bands, springs, coils, or flex rods.
In a preferred embodiment, the present invention provides for one or more adjustable elastic resistance cords or flat bands that allow the user to conduct exercise utilizing multiple types of resistance (weights and elastic resistance cords or flat bands) in one system.
For instance, a user may conduct hand or leg resistance exercises utilizing elastic resistance cords or flat bands in combination with or separate from weights.
The strength of the elastic resistance cord or flat band and the range of motion may be varied without the need to substitute or add another elastic resistance cord or flat band.
The present invention permits a user to adjust the level of resistance quickly and easily over a greater range and allows for greater ease and speed of adjustment of resistance when conducting exercises.
Further, the invention provides a means of securely attaching an elastic resistance cord or flat band for use in exercise thus increasing the number of types of exercise that a user may perform.
Further, the invention provides for a flat, compact, and portable exercise surface on which the user may safely conduct many exercises..
As fewer resistance cords or flat bands or other items of equipment, are necessary to change resistance, the invention further provides a cost advantage over the prior art.
The invention further provides a system that is easily portable, compact, and easy to store.
The invention permits different types of exercises to be performed, e.g. aerobic exercises, strengthening exercises, and stretching exercises.
Further, different kinds of accessories may be used with the invention.
Exercises with the invention may be performed from different positions, e.g. standing, squatting, sitting, kneeling, and lying.
The invention may be used to exercise the whole body, e.g. upper, mid, and lower body parts including the arms, back, abdominals, and legs, to provide a total body workout.
The present invention is simple to use and is universally capable of use by anyone.
Accordingly, the invention has overcome the limitations of the prior art by providing an easily adjustable resistance system which permits a rapid adjustment of length and strength without the need to change the components of the system.
At the same time, it also creates a revolutionary new hybrid type of resistance exercise consisting of two or more types of resistance, preferably weight and elastic resistance, and achieves all of the above advantages in one simple, useful, affordable device for the public..
SUMMARY OF THE INVENTION  The present invention provides for a combination of various types of exercise resistance.
In a preferred embodiment, the invention provides for elastic resistance cords or flat bands, which may be used in combination with any hand engagement structure, such as cord handles, dumbbell grip, bar, barbell grip, or glove, to conduct numerous exercises.
The elastic resistance cords or flat bands may be combined with resistance types such as traditional free weights or may used alone to create resistance during exercise.
As an elastic resistance cord or flat band is stretched and elongated under force, it provides increasing resistance.
The level of resistance provided by the elastic resistance cord or flat band is determined by the composition and dimension of the elastic resistance cord or flat band and the distance that the elastic resistance cord or flat band is stretched or elongated relative to its length..
In the present invention, a hand engagement structure, such as handles, handgrips, dumbbells, barbells, bars, elastic resistance cord or band grips, gloves or mitts, hand or finger loops, hand or wrist cuffs or straps, and ankle or foot cuffs of straps, may be (1) used as an elastic resistance structure alone, (2) used as a weight structure alone, or (3) used as a hybrid combination of weight and elastic resistance.
When elastic resistance cords or flat bands are used in combination with weights, resistance may be obtained through elastic resistance, weights, or a combination of these types of resistance.
The resistance of the elastic resistance cords or flat bands may be adjustable or fixed and the resistance provided by weights may be adjustable or fixed.
Accordingly, the resistance derived from these components may be in four forms.
In a preferred embodiment, resistance is derived through a combination of (1) adjustable weight resistance and adjustable elastic resistance.
In another form, resistance may be obtained through (2) a combination of adjustable elastic resistance and fixed weight resistance.
In another form, resistance may be obtained through (3) a combination of fixed elastic resistance and adjustable weight resistance.
Finally, resistance may be obtained through (4) a combination of fixed elastic and fixed weight resistance..
In the present invention, the strength of the adjustable elastic resistance cord or flat band may be changed by means of a slip free, length quick adjustment device.
The elastic resistance cord or flat band may be passed through the length quick adjustment device which may be quickly secured at various points along the length of the elastic resistance cord or flat band to change its effective usable length.
As force is applied to the elastic resistance cord or flat band in one direction, a locking mechanism within the length quick adjustment device secures the elastic resistance cord or flat band.
The length quick adjustment device may be instantly released by pulling the elastic resistance cord or flat band in the opposite direction.
The length quick adjustment device may be moved to various positions along the elastic resistance cord or flat band to change the effective usable length of the elastic resistance cord or flat band and thus vary the strength and range of motion of the elastic resistance cord or flat band.
Free weights or other types of exercise equipment may be used in conjunction with the elastic resistance bands.
Elastic resistance cords may also be used in exercise, and the usable length may be adjusted in a similar manner.
Various exercises may be easily be performed utilizing adjustable elastic resistance cords or flat bands in this manner, alone or in conjunction with other types of exercise equipment..
Thus, the invention provides for a revolutionary new type of resistance exercise that draws on attributes of one or more types of resistance.
When used in combination with the length quick adjustment device, the resistance provided by the elastic resistance cord or flat band is quickly and easily adjustable, and firmly secured.
The invention also creates a new method of exercise whereby unique programs can be developed utilizing elastic resistance cords or flat bands referring to numbers, color zones, or other types of markings on the elastic resistance cords or flat bands to assist in adjusting the level of resistance quickly and easily, for different movements/exercises in an exercise workout program..

DETAILED DESCRIPTION OF THE INVENTION Combination of More than One Resistance Type  The present invention is a combination of one or more types of resistance.
The invention combines aspects of one or more varied types of exercise including but not limited to a combination of weights, elastic resistance cords or flat bands, springs, coils, flex rods, gyroscopes, magnetic resistance, pneumatic resistance, hydraulic resistance, friction brake resistance, and the weight of a user's own body.
The invention is any device that uses one or more types of resistance, but preferably combines two types of resistance.
The level of resistance provided by each type of exercise may be fixed or adjustable..
In a preferred embodiment of the invention, elastic resistance cords, flat bands or springs are used in combination with weights such as dumbbells, bars, or barbells.
In this embodiment, resistance may be obtained through elastic or spring resistance, weights, or a combination of these types of resistance to form a new “hybrid” form of resistance.
By way of example, the invention can include use of a cable attached to a coil spring and friction brake assembly such that as a user pulls on the cable, he obtains resistance from the spring and the friction brake.
As used herein, elastic resistance refers to both elastic and spring resistance.
The resistance of the elastic resistance cords or flat bands may be adjustable or fixed and the resistance provided by weights may be adjustable or fixed..
Resistance Combinations  Accordingly, the resistance derived from these types of resistance may be in four forms: in a preferred embodiment, resistance is derived through (1) a combination of adjustable elastic resistance and adjustable weight resistance. (2)
In another form, resistance may be obtained through a combination of adjustable elastic resistance and fixed weight resistance. (3)
In another form, resistance may be obtained through a combination of fixed elastic resistance and adjustable weight resistance. (4)
Finally, resistance may be obtained through a combination of fixed elastic and fixed weight resistance..
Hand Engagement Structures  Also in a preferred embodiment of the invention, elastic resistance may be combined with any hand engagement structure.
The hand engagement structure includes any structure which may be held by hand and includes but is not limited to a handle or grip, a hand held weight, such as a dumbbell, barbell, bar, a glove, a mitt, one or more loops capable of fitting around the hands or fingers of a user, or wrist cuffs.
The hand engagement structures can also be used to engage the foot or ankle or other body parts..
Preferred Combinations of Resistance Types.
In a preferred embodiment, the present invention provides for a combination of any hand engagement structure, such as but not limited to a glove, finger or hand loops, dumbbell, bar, barbell, or handle or grip with an elastic resistance cord or flat band 110 .
Further, a weight (for instance a weight plate) utilizing the force of gravity, may be attached to a handle or grip for elastic resistance cords or flat bands to provide additional resistance..
The most preferred forms of the invention are (1) one or more elastic resistance cords or flat bands 110 in combination with one or more handles 200 , (2) one or more elastic resistance cords or flat bands in combination with weights such as a dumbbell, and (3) one or more elastic resistance cords or flat bands 110 in combination with weighted gloves such that resistance is obtained during exercise from the elastic resistance cord or flat band 110 in combination with a weight.
In a preferred embodiment, the invention may utilize lighter hand weights such as a weighted handle 200 or a dumbbell in combination with elastic resistance.
However, a heavier weight, such as is typically used with a barbell, may also be used in conjunction with elastic resistance cords or flat bands.
Additionally, a user may perform exercises utilizing adjustable elastic resistance cords or flat bands alone, or a weighted handle 200 or dumbbell alone as described herein.
Moreover, the invention permits a user to move more quickly and easily from a form which derives resistance solely from weight to a form which derives resistance solely from elastic resistance.
Further the invention permits a combination of both forms of resistance as preferred by the user..
The combination of a handle 200 with an elastic resistance cord or flat band 110 may contain the following unique components: (1) a means of attaching weight to the handle, (2) an elastic resistance cord or flat band 110 ; (3) a means for adjusting the usable length of the elastic resistance cord or flat band 110 such as a length quick adjustment device 10 capable of attachment to the elastic resistance cord or flat band 110 at any point along its length; (4) a means for attaching the handle 200 to the length quick adjustment device 10 which includes a strap 220 connected to the handle 200 and a finger clip 46 (or two sided finger clip 47 ) connected to the strap 10 and the length quick adjustment device 10 ; (5) a finger clip 46 (or two sided finger clip 47 )
attached to one end of the elastic resistance cord or flat band 110 for attachment of the elastic resistance cord or flat band 110 to an anchoring structure; and (6) an anchoring structure of any type but preferably a moveable board, pad 350 , or aerobic step.
These components allow a user to vary range of motion, amount of resistance, and method of exercise with ease and allow a user to conduct a total body workout virtually anywhere involving all types of exercise such as aerobic, stretching and strengthening.
As indicated, weights, gloves or weighted gloves may also be combined with elastic resistance cords or flat bands 110 to create a “hybrid” resistance which ranges from weight resistance only to elastic resistance only and permits a combination of elastic and weight resistance..
2. Elastic Resistance and Means of Adjusting Resistance  An elastic resistance band is generally of flat construction while an elastic resistance cord is generally of a tubular rounded construction.
Either elastic resistance cords or flat bands may be utilized in the invention, and as used herein, a reference to one includes a reference to the other.
Elastic resistance may be adjusted by a number of means: (1) addition or subtraction of elastic cords, (2) substitution of cords of different strengths or lengths, and (3) adjusting the usable length of an elastic cord.
The elastic resistance cord or flat band 110 may also be connected to other equipment which provides additional resistance through the force of gravity.
In this way, the elastic resistance cord or flat band 110 may combine aspects of elastic based resistance and gravity based resistance against actions of the user..
For instance, as shown in FIG.
9 , the elastic resistance cord or flat band 110 , or a plurality of elastic resistance cords or flat bands, may be connected at one end to a handle 200 by connecting the elastic resistance cord or flat band 110 to at least one hasp 243 positioned on a handgrip 245 of the handle 200 .
The handgrip 245 may be a sleeve which is capable of rotating around the handle 200 so that the handgrip 245 remains stationary with respect to a user's hands notwithstanding movement of the handle 200 during exercise.
In a preferred form, the handgrip 245 may be padded to better enable the user to grasp the handle 200 .
The hasp 243 may be oriented perpendicular to the direction of the handgrip 245 so as to permit the fingers of a user to easily pass around the hasp 243 when grasping the handgrip 245 during exercise.
The elastic resistance cord or flat band 110 may be permanently attached to the handle 200 or may be detachable.
In a preferred embodiment, the elastic resistance cord or flat band 110 may be connected to a finger clip 46 (or two sided finger clip 47 ) which is attached to the handle 200 such that the finger clip 46 may be opened to release the elastic resistance cord or flat band 110 from the handle 200 .
Additionally, elastic resistance cords or flat bands may be connected to each other sequentially by one or more finger clips or other means of attachment to extend the overall usable length of the cords or flat bands..
Elastic resistance may be fixed or adjustable.
Various means may be used to adjust the strength of an elastic resistance cord or flat band 110 .
For instance, the user may increase or decrease the number of elastic cords being used in a workout.
The invention also allows for the complete removal of a resistance cord and substitution of another cord of a different resistance to adjust the strength.
Alternately, the strength of an elastic resistance cord or flat band 110 may be varied by changing the usable length of the elastic resistance cord or flat band.
Under static conditions, when an elastic resistance cord or flat band 110 is not elongated and relaxed, the elastic resistance cord or flat band is not under tension and provides little resistance against the action of a user.
As the elastic resistance cord or flat band 110 is stretched and elongated under force, its potential energy builds and it provides increasing resistance.
The level of resistance provided by the elastic resistance cord or flat band 110 may be determined by the distance that the elastic resistance cord or flat band is stretched or elongated in relation to its static length..
The invention describes a means of adjusting the resistance provided by the elastic resistance cord or flat band for a given range of motion during exercise, by adjusting its length.
As the resistance is increased, the user's ability to counter the increased resistance and complete the full range of motion will be decreased.
Accordingly, with increasing resistance, the user's effective range of motion will be decreased.
In a similar manner, as the level of resistance is decreased, the user will be better able to provide force against the resistance and his effective range of motion will be increased..
Elastic resistance cords or flat bands of the prior art provide limited means of adjusting the level of resistance provided by individual resistance cords or flat bands.
A user's maximum range of motion for a particular exercise is fixed based upon his own strength and bodily dimensions.
Accordingly, using the inventions of the prior art, if a user wished to adjust the level of resistance when conducting exercises using elastic resistance cords or flat bands, the user would need to utilize multiple cords or flat bands, at various stages of exercise, each providing varying levels of resistance.
For instance, when conducting curls, a user would need to utilize an elastic resistance cord or flat band, providing a certain level of resistance, and to increase the level of resistance, the user would need to add cords or utilize a different elastic resistance cord or flat band to change the level of resistance.
The present invention overcomes these limitations by providing an elastic resistance cord or flat band 110 capable of substitution and length adjustment thereby providing varying levels of resistance utilizing the same elastic resistance cord or flat band 110 ..
3. Length Adjustment Means  In the present invention, the length of the elastic resistance cord or flat band 110 , and thus the level of resistance that the elastic resistance cord or flat band 110 can provide, may be adjusted by any means but preferably by means of a slip free, length quick adjustment device 10 .
As shown in FIG.
1 , the length quick adjustment device 10 includes a housing 12 formed by mirror image housing halves 14 and 16 joined together at connecting line 18 .
Housing 12 includes a pair of side walls 20 , a rearward end 180 and a forward end 170 .
Housing 12 may be hollow except for the locking components described herein.
An elastic resistance cord or flat band 110 may pass through the housing between the side walls 20 from the forward end to the rearward end along the base 28 of the housing thereby defining a passageway for the elastic resistance cord or flat band 110 .
Further, the invention allows for the complete release of an elastic resistance cord, so that another cord of a different resistance or length can be substituted, using the same set of handles..
Each wall 20 includes a slot 30 inclined with respect to the passageway for the elastic resistance cord or flat band 110 .
Each slot 30 may extend from the upper portion of its side wall 20 at the rearward end 180 and may extend to about the center of its side wall near the forward end 170 .
Within the housing 12 is a locking pinion 32 having peripheral teeth 34 uniformly spaced along its outer surface for engagement with rack 36 within the housing parallel to the slots 30 .
Pinion 32 may be in the form of a roller having an axial shaft or pin 38 which may extend through the slots and about which pinion 32 rotates..
As shown in FIG.
6 , the length quick adjustment device path defined by the path of movement of the pinion 32 may include a start position 40 juxtaposed to the beginning of rack 36 .
Start position 40 includes an enlarged smooth surface 42 which permits the pinion to be located wherein the teeth 34 A located furthest from or diametrically opposite the elastic resistance cord or flat band 110 are out of contact with the rack while other teeth 34 B closer to the elastic resistance cord or flat band 110 begin to make contact with the rack 36 .
Teeth 34 C diametrically opposite teeth 34 A are disposed in the passageway for the elastic resistance cord or flat band and thus contact elastic resistance cord or flat band 110 ..
When it is desired to permit the elastic resistance cord or flat band 110 to pass through the housing 12 and thus permit some length or position adjustment of the elastic resistance cord or flat band 110 , the pinion 32 may be held in the start position by the user pressing against the shaft 38 which extends outwardly of the side walls 20 in a direction toward the rearward end 180 thereby minimizing contact between the teeth 34 and the elastic resistance cord or flat band 110 thus permitting the elastic resistance cord or flat band 110 to move generally freely through the housing.
In such manner, the length quick adjustment device 10 may be moved to any position along the elastic resistance cord or flat band 110 , or may be removed from the elastic resistance cord or flat band, without the teeth 34 engaging the elastic resistance cord or flat band.
If desired, there may be sufficient space in the enlarged smooth surface 42 area to move pinion 32 sufficiently toward the rearward end 180 so that none of the teeth is engaged with rack 36 .
Accordingly, different elastic resistance cords or flat bands may be removed from the exercise device and substituted for each other..
When a sufficient amount of the elastic resistance cord or flat band 110 has passed through housing 12 , pinion 32 may be released such that pinion 32 may travel toward the forward end 170 of the length quick adjustment device 10 .
The contact of the elastic resistance cord or flat band 110 with the teeth 34 causes the pinion to rotate and the engagement of the teeth 34 with the rack 36 moves the pinion toward the forward end 170 of the housing 12 with the teeth 34 progressively digging deeper into the elastic resistance cord or flat band 110 until the elastic resistance cord or flat band 110 can no longer move.
FIG.
6 shows the condition in which the elastic resistance cord or flat band 110 is locked into position by the pinion 32 ..
The length quick adjustment device permits multiple cords or bands to pass through it, although a single cord or band is preferred.
It is to be understood that the length quick adjustment device 10 may also accommodate the passage of additional elements through the length quick adjustment device 10 such as ropes, lines, cables, cords, strings, or hollow members such as elastic tubes and other forms of tubing.
The length quick adjustment device 10 may also accommodate a flat elongated material 120 or other shaped elongated materials which are capable of passing through the length quick adjustment device 10 , and the invention is not limited to use of an elastic resistance cord or flat band 110 in conjunction with the length quick adjustment device 10 .
The length quick adjustment device 10 may also accommodate more than one elastic resistance cord or flat band or other elongated material..
As shown in FIG.
1 and FIG.
2 , the housing 12 may include a slot 44 into which a finger clip 46 of any suitable known construction may be attached.
As used herein and as shown in FIG.
27 , a two sided finger clip 47 , capable of clipping onto an object from either side, may used interchangeably with finger clip 46 .
Finger clip 46 in turn may be engaged with D-ring 48 which may be secured to a strap 220 connected to handle 200 ..
It is to be understood that the illustrations in FIG.
1 and FIG.
2 of components that may be used with the length quick adjustment device 10 are merely stated for exemplary purposes and is not intended to limit the scope of the invention.
Accordingly, the length quick adjustment device 10 may be used wherever it is desired to permit adjustment in the length or location of an elongated material and then readily lock the material in place to prevent further movement of the material..
In an alternate embodiment, as shown in FIG.
8 , the length quick adjustment device 10 may have a housing 12 which defines an interior chamber 130 containing a top surface 160 .
The chamber 130 also may contain a ball 140 or a similar object which is capable of rolling along an inclined surface 150 within the length quick adjustment device 10 .
The distance between the ball 140 and the top surface 160 of the chamber varies depending on the position of the ball 140 along the inclined surface 150 .
