Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] 1. Incorporation by Reference [0002] Applicant(s) hereby incorporate herein by reference, any and all U.S. patents and U.S. patent applications cited or referred to in this application. [0003] 2. Field of the Invention [0004] This invention relates generally to an exercise equipment and more specifically to such a device which makes use of the body weight of the user to apply resistance to exercise. [0005] 3. Description of Related Art [0006] The following art defines the present state of this field: [0007] Harris, U.S. Pat. No. 5,527,249 discloses a multi-function exercise machine which makes use of the body weight of an exerciser and has a base frame and a user support frame pivotably mounted. A lever arm mechanism for pivotably raising and lowering the user support frame against the user's weight is provided and comprises a handle bar having a lever arm depending therefrom and carrying a roller on the lower end thereof. An arcuate track is adjustably mounted to the base frame so as to provide an adjustable arcuate pathway for the lever arm roller to travel upon as the user pivotably motivates the handle bars and lever arm secured thereto in order to raise and lower the user support frame. Pushing and pulling exercises may be performed according to the selected position of the arcuate track. [0008] Dalebout et al, U.S. Pat. No. 5,733,229, discloses an exercise machine having a frame that has a base with an upright member. The upright member is formed to have a race to receive wheels to interconnect a second frame to the upright member. A cable and pulley structure interconnects exercise structures to cause movement of the second frame relative to the first frame. A user is positioned on a seat connected to the second frame to resist movement of the second frame relative to the first frame. A butterfly structure is provided that has a mechanical linkage to interconnect the link arms to a butterfly lever rotatably connected to deflect the cable of an associated cable arrangement. [0009] Habing et al, U.S. Pat. No. 5,330,405, discloses a multi-station exercise machine with a movable subframe on which a user sits while performing various exercises. The subframe is pivotally attached to a stationery frame and is supported by a lever arm that is also pivotally attached to the stationery frame. The pivot arms coupling the subframe to the stationery frame bear against a carriage that is located on the lever arm. A cable and pulley system couples the lever arm to the various operable members of the apparatus so that a selectable ratio of the weight of the subframe, including the user, is communicated as exercise resistance. The amount of weight that is coupled to the operable members is selected by positioning the carriage along the lever arm. This adjustment also varies the height to which the subframe is lifted by the exercise stroke and hence the effort that must be exerted by the user. [0010] Richey, U.S. Pat. No. 4,949,958 discloses a weight lifting exercising device of the type wherein at least a portion of the weight lifted includes the user's own weighted. The device includes a frame having a first end and a second end. A platform also provides a first end and a second end, with the second end of the platform being pivotally mounted adjacent to the second end of the frame to permit the first end of the platform to move in a generally vertical arc. A bench has a first end, a second end, an upper surface and a lower surface. The first end of the bench is pivotally mounted to the frame adjacent to the first end of the bench to move in a generally vertical arc during the operation of the device. A carriage is disposed below the bench for supporting the second end of the bench on the platform. A first exercise bar is also provided. A first flexible cable has a first end, a second end and a middle portion. The first end of the cable is coupled to the first exercise bar, the second end of the cable includes a coupler for coupling the second end to a member on the device disposed at a level generally no higher than the upper surface of the bench. [0011] Our prior art search with abstracts described above teaches: apparatus that are heavy machines, difficult to fold for storage and move from one place to another. Such machines are also capability of exercising only one set, or at most, a few sets of different muscle groups of the user. The present invention overcomes these drawbacks and provides further related advantages as described in the following summary. SUMMARY OF THE INVENTION [0012] The present invention teaches certain benefits in construction and use which give rise to the objectives described below. [0013] In a best mode preferred embodiment of the present invention, an exercise apparatus is placed on a supporting surface. The apparatus has a linear support frame and a supporting strut depending from an elevated end of the linear support frame to maintain the linear support frame at a selected angle with respect to the supporting surface. A user support strut provides a user support such as a seat, and is pivotally engaged with the linear support frame proximal its elevated end. A raising strut is pivotally engaged with the linear support frame at their lower ends. An intermediate strut is fixed between the user support strut and the raising strut, such that when the raising strut is pivoted upwardly, the seat strut is caused to pivotally move upwardly as well. For exercising, cables are mounted to the apparatus so that the user is able to apply force to the raising strut to lift the users own weight in a pivoting action. [0014] A primary objective of one embodiment of the present invention is to provide an apparatus and method of use of such apparatus that yields advantages not taught by the prior art. [0015] Another objective is to provide such an apparatus capable of being made with light weight, portability, ease of setup and storage and adjustability for level of difficulty. [0016] A further objective is to provide such an apparatus capable of using the body weight of the user to apply restraining forces for exercising the user's muscles. [0017] Other features and advantages of the embodiments of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of at least one of the possible embodiments of the invention. BRIEF DESCRIPTION OF THE DRAWINGS [0018] The accompanying drawings illustrate at least one of the best mode embodiments of the present invention. In such drawings: [0019] FIG. 1 is a perspective view of one embodiment of the invention; [0020] FIG. 2 is a side elevational view thereof showing the use of a cable routed for arm, chest and shoulder exercises; [0021] FIG. 3 is a side elevational view thereof showing the use of a further cable routed for further arm and also leg exercises; and Continue reading about Foldable gravity resistance gym...
