Description
- The present invention generally relates to exercise equipment. More specifically, the present invention relates to light weight systems of physical exercise that stress the extensor muscles of the lower body and trunk.
- Exercise devices are becoming an increasingly more important part of our lives. As our society becomes more technologically advanced, we become more sedentary. Therefore we must rely on equipment to provide our muscles and organs with the stimulation necessary to maintain a healthy existence. Much of the equipment available is large, inexpensive and not practical for the average consumer to have in their home. Gyms and health clubs are not available to many people, especially in rural areas. In addition, with our busy lives, many simply do not have time to drive to the gym to exercise and return to home or work. As an alternative, home fitness products are inexpensive, lightweight products that offer an alternative to the traditional iron. These products must be functional, versatile and inexpensive to obtain and maintain.
- Weight loss is a key issue with most Americans. As such, a useful product must exercise the larger muscles in the body, specifically the extensor muscles of the hips and legs. These are the most powerful muscles in the body and can therefore do the most work. Increased work done by the body is extra energy expended. Therefore given a constant dietary intake this results in weight loss. In order for this to happen, the product must be used. A product that is too large and bulky, or where the user must sit on the ground to use it, is not found to be popular with the typical consumer. They like to be in a chair-like device, off the floor, where they can perform perform the exercises and when finished, pick the machine up and roll or carry it away.
- In one aspect, the invention features an exercise device with an upper frame supporting a seat back, the seat back enabling support of at least a portion of a torso of a user. A lower seat includes a lower frame that is movably or preferably, pivotally mounted to the upper frame. The lower frame includes a front support and a rear support for contact with a supportive surface (the floor); and an arcuate member secured to the upper frame substantially opposite to the seat back. When a force is exerted on the seat back toward the arcuate member, the upper frame translates up and back, rolling on the arcuate member while the front support remains in contact with the supportive surface and the rear support is elevated from the supportive surface.
- A tension arm may be included that has a first end movably mounted to the upper frame and a second end movably supported on the supportive surface. This movable support is preferably by use of a rolling element such as a wheel, bushing roller and a ball bearing. A tension band is preferably used in conjunction with the tension arm. It is releaseably mounted to the tension arm, optimally between the first and second ends of the tension arm by use of a band receiver, and also to the lower frame. A spring clip may be used to releaseably secure the tension band to the tension arm. The tension band may be attached to the lower frame by way of an anchor bar, which is optimally pivotally mounted.
- Handles may be mounted to the upper frame adjacent to the lower frame. In addition, a set of upper handles may be mounted to the upper frame, a distal end of said upper handles positioned adjacent the head of a user as they would be positioned on the device. A headrest may be included that is adjustably mounted to the upper frame.
- An exercise device will optimally include a pair of arcuate members spaced adjacent to one another and positioned such that there is a greater distance between the arcuate members father away from the upper frame relative to nearer the upper frame. The device may include a plate receiver mounted to the upper frame, thus enabling weight plates to be received thereon. This plate receiver is optimally positioned near the lower frame and most importantly positioned on a portion of the device that includes vertical movement during an exercise. A cover comprised of a high friction material is optimally placed on the arcuate members to insure a high frictional force between the supportive surface and the arcuate member.
- In another aspect, the invention includes a method of exercising including providing a device as previously disclosed and seating a user on the lower seat with the back of the user against the seat back. The user extends his legs and hip joints, pushing the seat back toward the arcuate member, rolling back on the arcuate member and elevating a lower portion of the upper frame while extending the body of the user. If a tension arm is provided, the method may include displacing the tension arm and elongating the tension band, thereby increasing work done by the user.
- The foregoing and other objects of this invention, the various features thereof, as well as the invention itself, may be more fully understood from the following description, when read together with the accompanying drawings, described:

- The present invention is an exercise device that enables a body extension movement and is convertible to a flat bench for multiple exercises. The basic version of the
device 12 is shown inFIG. 1 in the form of the preferred embodiment of the invention. Thedevice 12 includes aseat back 14 and alower seat 16 for supporting a user in a seated position, similar to a chair. A pair ofarcuate members 18 is positioned behind theseat back 14 to provide for articulating stable support when thedevice 12 is rolled back. In this view only onemember 18 is seen, and only one member is necessary in order that the device be functional. For increased stability, a pair ofmembers 18 is optimally used. This will become more evident further in the disclosure. The rearward movement constitutes the basis for the majority of the exercises that are performed on thedevice 12. To assist in this movement, two sets of handles are provided. The first set is thelower handles 20 that are mounted to the frame of thedevice 12 near the back of thelower seat 16. The user, when seated in thedevice 12, can extend his arms down, grasp thehandles 20 and offer a stabilizing reaction to sliding up and off of the seat back 14 during the extension exercise. The second orupper handles 22 offer an alternative support during the basic exercise in that the arms of the user are raised and “push” to secure his body. This alternative positioning of the body stresses the deltoid muscles and triceps rather than the biceps and forearms when using the lower handles 20. Subtle variations such as this offer a key versatility to the capabilities and therefore the success of the product. The upper handles 22 have another function in that thedevice 12 can be fully extended back on the arcuate members 1o creating a bench. The upper handles 22 are then positioned to provide stability to allow abdominal exercises to be performed.Arcuate members 18 each have one end connected toupper frame 30 via transverse stub extensions (not numbered) and effectively form extensions of the lower ends of upper handles 22. The upper ends of thearcuate members 18 can also attach to the frame substantially orthogonal to the lower ends of the upper handles 22. The opposite ends ofarcuate member 18 are connected to lowerframe member 34 or handles 20. - Another key element in this version of the invention is also shown here. A
tension arm 24 is movably mounted to thedevice 12 behind the seat back 14. Thisarm 24 is supported by asupport 26, preferably in the form of a wheel or roller as shown here. Thesupport 26 is supported on the floor on which thedevice 12 sits and translates away from the seat back 14 as thedevice 12 rolls back on thearcuate members 18. When this happens thetension bands 28 elongate, thus work is done.Different tension bands 28 can be used for varying the resistance. For example, thedifferent tension bands 28 can be made thicker, of different materials, etc. - In
FIG. 2 thedevice 12 is shown from the rear, thereby illustrating the structural elements in this the preferred embodiment. Anupper frame 30 provides the structural support for the seat back 14, thearcuate members 18,lower handles 20,upper handles 22 and a first end of thetension arm 24. Thetension arm 24 is pivotally mounted to theupper frame 30 by way of aclevis 32. The second key frame element is thelower frame 34. Thelower frame 34 provides a secure mounting surface for thelower seat 16 and provides a base mount for thetension bands 28. Optimally, twotension bands 28 are used, as is shown here, that are mounted between thetension arm 24 and thelower frame 34. In this position, thedevice 12 is at “rest” and therefore thetension bands 28 are not extended significantly beyond their resting length. At the second end of thetension arm 24, twosupports 26 are provided. As previously noted, these are intended to move or translate along the floor or other supportive surface. Here, twosupports 26 are used. This is not necessary for the function of thedevice 12 in that asingle support 26 or roller could be used. Two supports 26 are used to offer greater stability to thearm 24 and thedevice 12 when in use. - Another aspect of the invention illustrated here is an
adjustable headrest 36. Theheadrest 36 is comprised of ahead pad 38 and amale post 40. Themale post 40 is telescopically received by theupper frame 30 and secured in a desired position by placement of a pin in one of the tube holes 42, which is received in a corresponding one of a plurality of spaced apart holes (not shown) inmale post 40.Additional holes 44 are used to secure the seat back 14 to theupper frame 30. The versatility of themovable headrest 36 is another advantage to more adequately fit a variety of physical types of users. - Another view of this embodiment is shown in
FIG. 3 . Here the seat back 14 andlower seat 16 have been separated to show the structure of thedevice 12. Of specific interest in this view is thelower frame 34. Thelower frame 34 is pivotally mounted to theupper frame 30. When in this position the bottom portions of thearcuate members 18 are in contact with the floor as well as the supports 26. In this, the starting position of the exercise, thelower seat 16 must substantially support the body weight of the user. This load is transferred to thelower frame 34, which must be supported by the floor on which thedevice 12 sits. For that, thelower frame 34 must also have supports. Theupper frame 30 is supported from behind by thearcuate members 18. Theupper frame 30 is pivotally mounted to thelower frame 34, which includes front supports 46. Without arear support 48, the area of pivotal connection of theupper frame 30 and thelower frame 34 would hit the floor. As the exercise is performed, with the weight of the user on thedevice 12, the initial movement of this pivotal connection area would drag on the floor until enough vertical displacement was achieved. By rolling back on thearcuate members 18, the lower frame must be horizontally displaced. Because of that, the preferred embodiment of the front supports 46 and therear support 48 are wheels or rollers. A slider or pad with a low coefficient of friction could be used, but a rolling element is preferred. This eliminates any damage to the floor by thedevice 12 scratching along the initial movement of the exercise. - The
tension bands 28 are mounted between thetension arm 24 and thelower frame 34. Thelower frame 34 acts as an anchor to provide a reaction force to the tension applied by thetension bands 28 when they are stretched due to the displacement of thetension arm 24 when in an extended (rolled back) position. To aid in the alignment of thetension bands 28 with minimal axial slippage and associated wear, ananchor bar 50 is provided. Theanchor bar 50 is pivotally mounted to thelower frame 34 and therefore acts as an extension of thelower frame 34. The anchor bar includes aband receiver 52 in the form of a rod that accepts the end of theband 28. Theanchor bar 50 is shown here to be pivotally mounted to thelower frame 34 at the axis of the wheel, which is therear support 48. This is a design choice and considered to be the preferred embodiment, but that precise location of the mounting of theanchor bar 50 to thelower frame 34 is not considered critical to the invention. The ability of theanchor bar 50 to move or pivot relative to thelower frame 34 is of value in that as thedevice 12 is extended backward, the positions of thetension bar 24 relative to thelower frame 34 and relative to theupper frame 30 both change. The rotational displacement of thelower frame 34 relative to theband 28 can be great. When theband 28 is under tension this load produces a great deal of friction on theband receiver 52. Theband 28 is traditionally a molded rubber bar, with holes to receive theband receiver 52. This is not a good bearing surface. A better bearing can be provided in the pivotal attachment of theanchor bar 50 to thelower frame 34, thus reducing wear on theband 28, increasing its functional life and reducing its likelihood to inadvertently come off during the exercise session. Also regarding safety, acover 53 comprised of a high friction material is optimally placed on thearcuate members 18 to insure a high frictional force between the supportive surface and the arcuate member. This reduces the likelihood of thedevice 12 slipping when used and makes it reduce noise and potential damage to the floor. - The starting position of the
device 12 is shown inFIG. 4 , from the side with auser 54 positioned on thedevice 12. Theuser 54 is seated on thelower seat 16 and for illustration sake is shown grasping alower handle 20 with his left hand and anupper handle 22 with his right hand. Theuser 54 has his back positioned against the seat back 14 and hisfeet 56 on the floor in front of thedevice 12. - The final position is shown in
FIG. 5 where theuser 54 has extended hisleg 58 and hip joints, pushing against the floor, with thefeet 56 relatively stationary, pushing the seat back 14 back on thearcuate members 18. This results in rolling thedevice 12 back on thearcuate members 18 raising therear support 48 of thelower frame 34 off the floor. At this degree of rearward extension, theuser 54 may be raised off thelower seat 16. Thefront support 46 maintains contact with the floor in that it is pivotally mounted to theupper frame 30. This allows the user to fully extend his hips and legs without being physically inhibited by any aspect of thedevice 12. If thedevice 12 were extended further, depending upon the subtleties of the pivotal connection of thelower frame 34 to theupper frame 30, a limit of the angular displacement can be built in. In this case thefront support 46 would eventually be raised off the floor. This provides more work done by the user in that thisseat 16 structure has weight and is being vertically displaced. As long as thelower seat 16 and the seat back 14 can become substantially coplanar, there is little potential for thelower seat 16 to interfere with the movement of thelegs 58 of theuser 54 and therefore can reach a range limiting stop relative to the seat back 14. The angular displacement of thetension arm 24 is also illustrated here. InFIG. 4 the angle between theupper frame 30 and thetension arm 24 is noted by the angle α. When extended, as inFIG. 5 , the new angle α1 is visibly greater than the acute angle α. This angular displacement results in an increased length of thetension bands 28 between these two figures. Thetension band 28 is a tension producing spring that when elongated applies a force that opposes this elongation. Thus, work is done by the user to elongate thetension bands 28. The user pushing against the seat back 14, stabilized by thelower handle 20, pushing on theupper handle 22 or any combination thereof, does this work. - The
device 12 is shown in the elongated or extended position inFIG. 6 with the seat back 14 displaced to better view theelongated bands 28 and the function of theanchor bar 50. As thetension arm 24 is displaced rearward and thedevice 12 rolls onto thearcuate members 18, the angle between thelower seat 16 and thetension band 28 changes dramatically. The angular displacement of thetension band 28 relative to thelower seat 16 is roughly twice that of the angular displacement of theband 28 relative to thetension arm 24. Thetension band 28 is an elastic element, as previously note and preferably made of a natural or synthetic rubber material. These materials typically have a high coefficient of friction with smooth steel. Theband receivers 52 are typically smooth steel. Therefore, continuous rotation under tension can create a great deal of wear. The applicants have overcome this issue by using ananchor bar 50 that is pivotally mounted to thelower frame 34. This movinganchor bar 50 enables virtually no angular rotation of theband 28 on theband receiver 52 of theanchor bar 50, which acts as a part of thelower frame 34. This greatly increases the life of thebands 28 when used on thedevice 12. - Shipping size is another issue to home fitness products. In many cases it is desirable for the product to ship in a “knocked down” state requiring some assembly by the user. The value of the knock down products as to the shipping costs is greatly reduced, which can be passed on to the consumer as a lower sale price. In doing this, it is desirable to design the components so that they take up a minimal amount of carton size without compromising the function of the product.
- Stability of the device while in use is always an issue of concern. The base must be wide enough to allow for normal side-to-side forces without tipping the device over. This is ever apparent when getting on to or exiting the device. The applicants addressed this issue in several ways. A top or plan view of the
device 12 is shown inFIG. 7 . Here thelower seat 16 is quite apparent in this view along with theupper handles 22 and the lower handles 20. Thetension bar 24 extends from the back of thedevice 12 with thetension bands 28 in place as previously disclosed. Two unique features are apparent in this view. First, thearcuate members 18 are cantered or flared to the outside. This is done to increase the width of the contact points of thearcuate members 18 with the floor while maintaining a minimal sized frame structure to support themembers 18. - The second feature is the width of the
supports 26 on thetension bar 24. These supports 26 are purposefully positioned to add to the stability of the device, both in a starting position (as when entering and exiting the device 12) and in an extended position as when being used. This support width also aids in stability in case only one of thetension bands 28 would be used. The eccentric load on the frame members would be decreased by the increased width of thesupports 26 on the floor. - A partially exploded view of the
device 12 is shown inFIG. 8 . This better illustrates the knock down capability of thedevice 12. It is not necessary that the consumer assembles all components, and in most cases it is preferable not to do so. This does give the manufacturer the assembly options. In addition, this view illustrates one example of the manufacturability of thisdevice 12. The elements are as previously disclosed, with the exception of two sets ofclips 60. Theseclips 60 can take a variety of physical forms but have been determined by the applicant to preferably be a form of a torsion spring. Theclips 60 can be provided in pairs, as shown here and connected by atether 62. This can connect an upper to alower clip 60, as shown here, or a right to aleft clip 60. Thetether 62 is not critical to the function of thedevice 12, but only added as prevention against losing theclips 60. The function of theclips 60 is to be received by theband receivers 52 on the outside of thebands 28. Theclips 60 apply a frictional force to theband receiver 52 to releaseably secure theband 28 on theband receivers 52. This prevents the inadvertent dislodging of aband 28. This could be especially detrimental when thedevice 12 is extended and thebands 28 are under tension. - An alternative to the preferred embodiment is shown in
FIG. 9 . In this embodiment, the lower portion of the upper frame, or the bases of thehandles 20 are fitted withplate receivers 64. Theplate receivers 64 enable receivingweight plates 66. Theseplates 66 are shown here in two different sizes, or weights. The amount and combination would be completely up to the user and the structural capability of theweighted device 68. Theweight plates 66 are shown to be in position on thedevice 68 on the rear side and exploded on the far side. The purpose of theweights 66 is to provide additional weight for additional resistance during the exercise. As was illustrated inFIG. 5 , this lower portion of the upper frame is elevated during the extension exercise. Therefore, adding additional weight would increase the work done by the user, and therefore the load on the muscles of the user. Thetension bands 28 on thetension arm 24 can still be used in this embodiment of the invention. - A second alternative to the preferred embodiment is shown in
FIG. 10 . As previously disclosed, the presence of theweight plates 66 on theplate receivers 64 provides additional resistance to the muscles of the user performing the exercise. In light of that, it is possible to add enough resistance thoughweight plates 66 to substitute for the previously disclosedtension arm 24 andtension bands 28. This embodiment illustrates this version of thedevice 70 without the tension producing elements of thetension arm 24 andtension bands 28. The general function of thedevice 70 would be identical to that as previously disclosed only with the noted parts being absent.
