Description

[0001] Portable bench press with elastomers [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bench press using an elastic body capable of performing muscle strength strengthening exercises of various body parts using an elastic body such as a spring or the like while lying on a bench or sitting. More particularly, The present invention relates to a portable bench press using an elastic body.

The bench press is designed to be able to sit on a couch or sit and exercise, and is one of the Big Three instruments for weight training.

The basic bench press is designed to lift the barbell while lying on a long chair. It is a fitness device that exercises muscles around the deltoid muscle, deltoid muscle, triceps and shoulders and the trapeze muscle. A variety of bench press machines have been developed, including complex or modified versions.

However, since such exercise apparatuses are fixedly installed in a specific place, they can not be carried and can only exercise in a specific place where the exercise apparatus is installed.

As a portable exercise device, Korean Utility Model Registration No. 456732 [Stretching exercise device for preventing shoulder pain that is easy to carry] and Korean Utility Model Registration No. 451767 [Portable lower body exercise device] have been proposed, It is not possible to substitute a bench press, one of the Big 3 mechanisms for weight training, because it is constructed to be capable of only muscle strength or stretching for a specific region with a simple structure, and its purpose and effect are completely different from each other.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems associated with the conventional bench press exercising apparatus as described above, and in particular, a bench press which is constructed to be able to perform a muscle force exercise by lying on a bench or pulling an elastic body, The present invention provides a portable bench press using an elastic body which can be easily moved.

According to an aspect of the present invention,

A support leg, an elastic body, a wire provided with a motion handle, a wire conveyance guide means for smoothly conveying the wire, and the like,

The bench portion is provided with a hinge folding portion at the center and a frame having a predetermined thickness at a lower corner so as to provide a storage space inside the frame. The support leg is hinged to a lower portion of the bench portion, And it is folded to facilitate carrying and moving.

According to the present invention having the above-mentioned solution, when the support leg and the wire guide bar are folded and placed in the storage space, the movement handle and the wire are placed in the storage space, and then the bench portion is folded through the hinge folding portion, Since all the main constituent parts constituting the present invention are located in the space, the user can easily carry the portable case like the bag such as Attache Case, and the portable grip 24 provided at one side of the bench part is gripped In addition, the user has the effect of being able to exercise at any time in any place, such as an extra time between tasks, or outdoor activities such as long distance trips, camping, etc. The expected effect is a truly inventive invention.

A bench portion 20 on which a user can lie down or sit on his / her back;

A support leg 30 provided on both sides of the lower portion of the bench portion 20;

An elastic body (40) capable of returning to its original state when an external force is released when the other end is pulled by an external force in a state where one end portion is fixed to the lower portion of the bench portion (20);

A wire (50) having one end fixedly coupled to the other end of the elastic body (40) and the other end having a grip handle (51) capable of gripping;

A first wire transfer guide means 60 provided at a lower portion of the bench portion 20 and smoothly transferring the wire 50 while smoothly bending the wire 50 without friction with other portions; Respectively,

If the user repeatedly repeats the process of lying on or sitting on the bench portion 20 and holding the exercise handle 51 and pulling and releasing it, the elastic body 40 is stretched and returned to its original state, But,

The bench 20 is folded with the hinge folding section 22 at its center, and the frame 21 having a predetermined thickness is formed on the lower edge of the bench section 20 so that both sides of the frame 21 are mutually symmetrical with respect to the hinge folding section 22 And a storage space (23) is provided inside the frame (21)

The support leg 30 is hinged to the lower portion of the bench portion 20 so as to be folded and folded, and is configured to be seated in the storage space 23 when folded,

The elastic body 40, the moving handle 51, the wire 50, and the first wire transfer guide means 60 are sized to be seated in the storage space 23,

The bench portion 20 is folded in a state where the movement handle 51, the wire 50 and the wire conveyance guide means are positioned into the storage space 23 after the support leg 30 is folded, .

The bench portion 20 can be made of various materials such as wood, synthetic resin, and metal. Further, the bench portion 20 can further be combined with the cushioning material to facilitate the use thereof. have.

In addition, the bench portion 20 is folded and unfolded with a separate, centered hinge folded portion 22,

A frame 21 having a predetermined thickness is arranged on the lower edge of the hinge folding section 22 so as to be symmetrical with respect to the hinge folding section 22 so that a storage space 23 is provided inside the frame 21. Then, Folding the bench portion 20 in a state in which the support leg 30 is folded into the guide portion 50 and the movement handle 51, the wire 50 and the first wire transfer guide means 60 are positioned, It becomes easy.

At this time, the hinge folding section 22 is provided for the folding or unfolding of the bench section 20 and may be constituted on the bench section 20 or on the frame 21. In the embodiment of the accompanying drawings, it can be seen that the hinge folding section 22 is formed in the frame 21. [
