Abstract
The gymnastic implement is so conformed to train all the body's muscles, the resistance to the muscular action being represented by the user's weight. The implement has a board of suitable length for receiving the user's body in extended position and a frame member otherwise associable to said board and forming in its whole a lever system. The frame member has a first pair of parallel rods lying on a common plane, a second pair of parallel rods also lying on a common plane but inclined relative to the plane of said first pair of rods and elements interconnecting the rods of said first and second pairs transversely arranged relative to said board and forming the fulcrum and resistance of said lever system depending on the desired training to be carried out by the user.

Description
The invention relates to a gymnastic implement so conformed to train all the body's muscles, the resistance to the muscular action being represented by the same user's weight.
Several gymnastic implements are at present known but all are designated to train each only specific body's muscles so that, for training all the muscles, a plurality of different implements is required with the obvious consequent drawbacks such as, for example, costs and necessity to have available plenty of room.
The invention as claimed is intended to remove these drawbacks since it solves the problem of how to train all the body muscles by means of a single gymnastic implement having dimensions extremely reduced.
The gymnastic implement, according to the invention, is essentially characterised in that it comprises a board or body support platform of suitable length for receiving the user's body in extended position and a frame member otherwise associable to said board and forming in its whole a lever system.
More particularly, such a frame member comprises a first pair of parallel rods lying on a common plane, a second pair of parallel rods also lying on a common plane but inclined relative to the plane of said first pair of rods and elements interconnecting the rods of said first and second pairs transversely arranged relative to said board and forming the fulcrum and resistance of said lever system depending on the desired training to be carried out by the user.
The invention is described in detail below with reference to drawings which illustrate only one specific embodiment, in which:
FIG. 1 is a perspective view of a gymnastic implement in accordance with the invention;
FIG. 2 is a perspective view of the frame member only; and
FIGS. 3 to 12 are views showing some of the possible exercises that can be performed by using the implement shown in FIG. 1.
Referring to FIGS. 1 and 2, the implement according to the invention comprises a board 1 and a frame member, generally shown at 2 in FIG. 2, constituting a lever system as a whole.
On its bottom surface, said board 1 has a series of transverse seats 3 and, on its upper surface, a foot rest 4 and retaining belts 5.
The frame element 2 comprises a first pair of parallel rods 6 interconnected by a transverse rod 7 of larger width than that of the board 1. A second pair of parallel rods 8 branch off from said rod 7 and have the ends thereof interconnected by a further transverse rod 9. The planes containing said rods 6 and 8 intersect at an angle .alpha., conveniently an angle of 130.degree., and a pair of idle rollers 10 is provided on the end portion of the board 1 on the side of said foot rest 4.
The gymnastic implement of the invention is basically based on the application on said lever system of tractions or pushes so as to accomplish contrasting movements, in which the opposite reaction to the drive action is constituted by the user's weight.
FIGS. 3 to 9 show some possible exercises that can be carried out by implement according to the invention, namely:
FIG. 3 shows the extension of the upper limbs from top to bottom with intervention of extensor muscles for the upper limb, pectoral or breast muscles and shoulder muscles;
FIG. 4 shows the rear-to-front rotation of the extended upper limbs, with the concern of deltoid, dorsal and pectoral or breast muscles;
FIG. 5 shows the front-to-rear flexion of the upper limbs with a movement similar to that of a rower with concern of the brachial biceps muscle and other flexor muscles of forearm on arm, dorsal muscles, shoulder muscles, trunk extensor, etc;
FIG. 6 shows the upward and forward thrust of the upper limbs at prone position; and
FIG. 7 shows the downward extension of the upper limbs and front flexion of the trunk with final rearward bust extension with concern of extensor muscles of the upper limbs and simultaneous action of the muscles for the shoulder, front side of the thorax, abdominal muscles and rear side of the trunk (dorsal muscles, para-vertebral muscles).
In FIGS. 8 to 12 further positions of the frame member 2 are shown for carrying out other exercises for training different muscular units.
By shifting the position of the hands along the rods 6 the force/resistance ratio of the lever system can obviously changed in order to increase or decrease the muscular strength required.
In a modified embodiment, not shown, rods 6 and 8 can be connected to the transverse rod 7 by means of any conventional device suitable to change the value of angle .alpha. and/or a device for changing the divergency of said rods 6 and 8, as desired.
Claims
What is claimed is:
1. In gymnastic apparatus for body training through user manipulation, a body support platform and a platform supporting and manipulating frame, said frame including first frame means for support and manipulation of said platform and second frame means for support and manipulation of said platform in cooperation with said first frame means, an intermediate portion between and interconnecting said first and second frame means, said first frame means including first platform engageable means for engaging said platform, said intermediate portion including second platform engageable means for engaging said platform, and mounting means on said support platform for selectively receiving said first and second platform engageable means to vary the manipulative relationship between the frame and platform, each of said platform engageable means selectively defining a fulcrum for pivotal manipulation of said frame and said platform upon physical engagement with and manipulation of said second frame means.
2. In the gymnastic apparatus of claim 1, said mounting means comprising a plurality of mounts at selected positions longitudinally spaced along said platform for selectively varying the position of engagement of either of said platform engageable means with the platform.
