A Tram/5Y5 United States Patent 3,445,109 SPRING OPERATED PHYSICAL EXERCISER Gert F. Kolbel, Kornstrasse 19-21, Hannover, Germany Filed July 5, 1966, Ser. No. 562,903 Claims priority, application Germany, July 2, 1965, K 56,529 Int. Cl. A63b 21/02 US. Cl. 27283 4 Claims ABSTRACT OF THE DISCLOSURE A physical exerciser has a substantially rectangular frame with two parallel long side members and two short transverse members interconnecting adjacent ends of these side members. A spanning member is movably guided upon the side members and is engaged by springs the opposite ends of which are rigidly fixed to the side members. A user can hold the spanning member in one hand and one of the short portions in the other hand to carry out push and pull exercises.
The present invention relates to a spring operated physical exerciser, which is especially intended for home use.
It is an object of the present invention to provide a physical exerciser permitting a multitude of exercises by which all muscles of the human body can be trained and yet being of a simple and robust construction.
Another object is to provide a physical exerciser which enables the user to perform gymnastic exercises in any position of this body, Whether standing up, sitting, lying down or kneeling, and therefore can exercise all the various muscles of the human body.
These and other objects of the invention will be set out in detail in the following description of an embodiment of the invention in connection with the accompanying drawing in which a view on the device embodying the invention is illustrated.
In the drawing:
FIGURE 1 is a side view of the top portion of the exerciser of the present invention.
FIGURE 1a is a similar view of the bottom portion.
The exerciser consists of a rectangular frame which is formed of two long straight chromium-coated steel side tubes '1 and 2 and of two tubular arc portions 3 and 4 connecting the tubes 1 and 2 with each other. Pushed over either tube 1 and 2 is a coil spring 5 the lower end of which is supported on a rigid stopping element 6 arranged at the connecting point of the tubular arc 4 with tube 1 or 2 respectively. The other end of either coil spring 5 is adjacent to a disc 7 which together with a sleeve 8 is slidably guided on tube 1 and 2 respectively. The two sleeves 8 are connected with each other by a transverse rod 9 constituting a spanning member the end portions of which project over the two straight tubes 1 and 2 of the frame and are shaped as handles 10. The central portion of rod 9 extending between tubes 1 and 2, is in the shape of a handle 11. In the inital position shown in the drawing, the two sleeves 8 abut against the ends 12 of the tubular are 3, the ends .12 having an enlarged external diameter. The coil springs 5 may be protected by a cover, such as rigid tubular sleeves 13 or folding covers or similar elastic members 14.
In the initial position shown in the drawing, the two coil springs 5 are under slight compression and thereby press the two sleeves 8 against the abutting ends of tubular are 3.
The exerciser may be used in a variety of ways. In one "ice hand, for instance, the user may hold the tubular arc 3 and in his other the medial handle 11, pulling these two handles apart, which causes the coil springs 5 to be additionally contracted. One may also grip the tubular arc 4 by one hand and the medial handle by the other hand and push both handles together. With its tubular are 4 the device may be supported on the floor to be used for pressure exercises, further by gripping and pushing downwards the handles 10 of a contraction of the abdomen muscles is performed. Placing a foot into the downwardly turned are 3 and pulling the handle 11 into upward direction is an exercise particularly beneficial to the arm mucles. In conjunction with supporting the device on the floor, against a wall or the ceiling, one may perform contraction exercises for all the muscles of the body. The device according to the invention is therefore extremely versatile and provides an overall training facility for the various muscular systems of the body.
Although this invention has been described with reference to a preferential embodiment it is to be noted that the invention is not limited to the details of this embodiment and that various modifications are possible within the scope of the appended claims.
My claims are:
1. A physical exerciser, comprising a substantially rectangular frame having two parallel long side members and two short transverse members interconnecting adjacent ends of said side members, a spanning member movably guided upon said side members and having a portion extending between said side members and end portions extending beyond said side members on opposite sides of said frame, all of said portions of the spanning member having the shape of handles, separate spring members upon said side members, each of said side mem bers having an abutment rigidly holding one end of the spring member carried by that side member, the other ends of said spring members resiliently engaging said spanning member, whereby a user may grip the spanning member with one hand and one of the two short transverse members with the other hand to carry out pull and push exercises.
2. A physical exerciser in accordance with claim 1, wherein the long side members are two straight tubes, said spring members being coil springs each of which is pushed over one of said straight tubes, the short transverse members which connect the ends of both tubes being tubular arcs.
3. A physical exerciser in accordance with claim 2, comprising a separate sleeve guided upon each straight tube, said spanning member interconnecting the two sleeves.
4. A physical exerciser as described in claim 2 in which an abutment for limitation of the movement of the spanning member is provided at the connecting point of the tubular arcs and the straight tubes.
