Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 gives a general view of the claimed exercise device representing the proposed technical solution and designed as a nondismountable rigid metal structure; and

(2) FIG. 2 provides a top view of the claimed exercise device representing the proposed technical solution and designed as a nondismountable rigid metal structure.

DETAILED DESCRIPTION

(3) The proposed technical solution will be further described with a reference to a particular embodiment thereof clearly demonstrating capability to attain the target technical result by means of the above-indicated entirety of essential features.

(4) In accordance with the technical solution (see FIGS. 1 and 2), an exercise device includes a support frame 1 with an axle 2. The axle 2 consists of two coaxial half-axles (not denoted in FIG. 1) positioned at the outer side of the levers 3. The latter are pivotally mounted to uprights, or posts, (not denoted in FIG. 1) of the support frame 1. Limiters, or stoppers 4 and 5 for limiting the movement of weight elements 6 are formed as transverse members located between the levers 3 and located on both sides of the axle 2. Guide member 7 for the weight elements, which is arranged between limiters 4 and 5, is formed as a bent rod having two rectilinear portions a and b connected by a rounded corner, or an arc c. The guide member 7 is installed in such a way that the axle 2 of the support frame 1 passes through the common center of gravity, CG, of the entire set of weight elements 6 located (for the orientation presented in FIG. 1) to the left of the rounded corner c. The rectilinear portions a and b of the guide member 7 are tilted to a horizontal plane at an angle corresponding to at least 2-3 irrespective of the position of the levers 3. The weight elements 6 are distributed, in the desired percentage ratio, between parts of the guide member 7 located on both sides of the axle 2. The limiter 8 of the positions of the levers is shaped as a U-shaped frame which is affixed to the levers 3. A bench 9 is mounted on the support frame 1. The device is affixed to a base 10 by means of fasteners 11.

(5) The exercise device functions as follows.

(6) In the initial state, the levers 3 rest on the limiter 8 and so are in their lowermost position, wherein the limiter 8 abuts the base 10. The entire set of the weight elements 6 is in its extreme left position. With the weight elements in this position, the axle 2 of the support frame 1 passes through the common center of gravity CG of the set of weight elements. In this position, a load applied to handles, or grips (not denoted in FIG. 1) of the levers 3 is minimal.

(7) Before beginning an exercise an exercising person adjusts a level of the load applied to the grips of the levers 3. With this purpose, he (or she) shifts a part of the weight elements 6 (selected in the desired percentage ratio of the total weight) along the guide member 7 all the way to the limiter 5. By shifting the total set of the weight elements 6 to the extreme right position, the load on the grips of the levers 3 is maximized. It shall be noted that a range of lifting the lever 3 upward is limited by the lower part of the limiter 8. In the course of exercise the exercising person grips the handles (not denoted in FIG. 1) of the levers 3 and periodically lifts and lowers them, lifting and lowering in this way the guide member 7 with weight elements 6.

(8) The safety of the exercising person during this process is ensured because inadvertent shifting of the weight elements 6 along the guide member 7 is impossible owing to that the tilting angles of the rectilinear portions (not denoted in FIG. 1) of the guide member 7 to the horizontal plane are made exceeding 2-3 irrespective of the position of the levers 3.

(9) With this exercise device, the exercising person can perform exercises in three different positions: when standing, sitting, or lying. For example, exercising person can perform exercises for training muscles of his (hers) back and legs when standing on the bench 9 or on the base 10.

(10) The exercising person can perform also the chest press exercise when sitting or lying on the bench 9. By performing this exercise the exercising person can train the muscle group of the shoulder girdle. When lying face upwards on the bench 9 and thrusting the legs against the handles (not denoted in FIG. 1) of the levers 3 one can perform exercises for leg muscles.

(11) By designing the exercise device as a stationary nondismountable rigid metal structure not requiring any technical servicing (such as adjusting, oiling, etc.), anti-vandal protection is attained, which allows to install the exercise device in open out-of-door areas, while easiness and speed of setting the load makes the device suitable for the wide use.

INDUSTRIAL APPLICABILITY

(12) The proposed exercise device does not create any problems in the course of its manufacturing. Moreover, the above description makes it clear that the claimed exercise device, as it is characterized in the single claim can be produced by employing known techniques and production means. The present invention can be effectively employed for training and development of main muscle groups of adolescents and adults by exercising on open out-of-door sports grounds.
