Description

Bench Press {Bench Press}

The present invention relates to a bench press, and more particularly, to a technique for increasing a movement efficiency by changing a structure according to a physical condition of a user and a part to be moved, while simplifying a lifting structure of a weight device.

Recently, in addition to a health club, a variety of fitness equipment has been used in homes and parks.

Among them, the bench press is a lifter that strengthens the user's arm and chest muscles while lifting and lowering the weight attached to the lifting bar by pushing up the lifting bar with the user lying on the bench.

Generally, a bench press installed in a health club or the like has a large scale because a connection between a lifting bar and a weight is made by a wire or the like.

In addition, since the elevation bar of the lifting bar is fixed at a constant level, it is impossible to change the structure to suit the body condition of the user, because the arm varies in length and chest width.

Therefore, if you continue exercising in a condition that does not fit your own body condition, you may have side effects that may cause muscle strain.

And the bench presses are different from each other according to the degree of opening of both arms of the user. In other words, when the gap between the arms is widened, the outer edge of the shoulder and the chest are strengthened. On the other hand, when the interval between the legs is narrowed, the inner edge of the chest is strengthened.

In addition to this, depending on the angle and the interval between the elbows and the waist, the movement part and the effect are different.

However, when the gap and angle between the lifting bars are the same as before, the user always has to exercise only in the same posture at all times. If the user desires to change the gap or angle of both arms, There is an inconvenience that the distance between the arms is narrowed or the angle between the elbow and the waist is arbitrarily adjusted during the elevation process.

In other words, the conventional bench press has a disadvantage that it is impossible to obtain a customized exercise effect for each user since the structure is fixed without consideration for changes in the physical condition and the moving part of the user.

Public Utility Model Publication No. 20-1986-0001360 (February 28, 1986)

The present invention has been proposed in order to solve the problems of the prior art,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The bench press according to the present invention includes a main body 10 and a seat 20, a weight 80, and a handle bar 60 as shown in FIGS. 1 to 3.

First, the main body 10 functions as a supporting frame of the present invention, that is, a skeleton, and an installation space of a lifting bar 61 and a weight 80, which will be described later. And the like.

For example, the shape of the main body 10 is not limited to a specific shape and can be variously modified as long as it supports a lifting bar 61 and can be attached to a weight.

A sheet 20 is provided on the main body 10.

The seat 20 serves as a seat for the user to lie down on the body 10. The seat 20 is in the form of a plate as a whole and is positioned in such a manner that the lower portion is seated on the upper rear edge of the body 10. [

A hinge 21 is formed between the lower portion of the seat 20 and the upper rear edge of the main body 10 and the lower portion of the seat 20 is connected to the main body 10 through a hinge, 21 in the form of a seesaw.

A support bar 22 for connecting to the support frame 30 to be described later is formed to extend straight downward on the lower surface of the rear end of the seat 20 and a plurality of fourth fastenings 22 are formed on the circumferential surface of the support bar 22, Holes 23 are formed at upper and lower intervals.

In this state, the support frame 30 is provided on the rear side of the main body 10. [

The support frame 30 supports the rear end of the seat 20 and serves as a footrest when the user lies down on the seat 20. The support frame 30 is formed in a box shape by connecting linear frames as a whole, (20).

At this time, a supporting tube 31 of a hollow tube type having an open upper end protruding upward is formed at a position vertically and vertically in line with the supporting bar 22 of the seat 20 of the supporting frame 30, and the supporting bar 22 Through the upper end of the support tube (31).

A plurality of third fastening holes 32 are arranged at upper and lower portions of the circumferential surface of the support tube 31 at a position facing the fourth fastening holes 23 of the support bar 22.

Therefore, when the seat 20 is rotated in a seesaw form about the hinge 21, the supporting bar 22 is vertically lifted and lowered in the guide pipe 50 in the course of the rear end being rotated up and down.

In this state, the second coupling pin (40) is detachably connected to the support pipe (31) and the support bar (22).

The second fastening pin 40 maintains the rotation angle of the seat by fixing the position of the support pipe 31 during lifting and lowering of the support bar 22 in the process of adjusting the rotation angle of the seat 20 while rotating the seat 20 So that the end of the pin is connected to the third fastening hole 32 and the fourth fastening hole 23 from the outside of the support pipe 31 in such a manner as to pass therethrough at the same time.

Therefore, when the seat 20 rotates in a seesaw shape and the rear end is raised or lowered, the position of the support bar 22 is fixed by the second retaining pin 40. Consequently, the rotation angle of the seat 20 is adjusted .

Accordingly, the angle of the seat can be freely adjusted. Accordingly, it is possible to set an appropriate angle according to the body composition of the user, and it is also possible to easily change the movement part by adjusting the angle.

The support pipe 31 and the support bar 22 are made of a magnetic material such as metal or magnet. The support pipe 31 and the support bar 22 are made of a magnet, When the second fastening pin 40 passes through the third fastening hole 32 and the fourth fastening hole 23, the surface of the second fastening pin 40 is pressed against the third fastening hole 32 by its own magnetic force, And the fourth fastening hole (23).

As a result, the phenomenon that the second fastening pin 40 is undesirably removed from the third fastening hole 32 and the fourth fastening hole is minimized.

In this state, the guide tube 50 is installed on the upper surface of the main body 10,

The guide pipe 50 serves to guide the lifting bar 61, which will be described later, up and down by a straight line. The guide pipe 50 is in the form of a hollow tube with its upper and lower ends opened as a whole, Respectively.

At this time, the both guide pipes 50 are positioned in a state where the lower end portion is fixed to the upper surface of the main body 10 through a bolt or the like and is erected upward.

In this state, the handle bar (60) is connected to the guide tube (50).

The handle bar 60 serves to transmit the weight of the weight 80 to the user and lift the weight 80. The handle bar 60 is connected to the lifting bar 61 and the connecting member 63, (65).

The lifting bar 61 is connected to the actual weight 80. The lifting bar 61 is in the form of a hollow tube having a predetermined length in the vertical direction as a whole. And is located near the inner bottom.

At this time, a plurality of second fastening holes 62 for fastening to the connecting member 63, which will be described later, are formed on the upper circumferential surface of the lifting bar 61, (50).

The connecting member 63 has a connecting function between the lifting bar 61 and a pull member 65 to be described later and a rotating angle adjustment function of the pull bar 60,

And a first fastening hole 64 for coupling with the lifting bar 61 is formed on one side of the circumferential surface so as to penetrate to the inside.

The connecting member 63 is positioned in a section of the upper side of the lifting bar 61 where the second fastening hole 62 is formed, and has a structure capable of lifting up and down along the vertical direction of the lifting bar.

The knob member 65 is a portion that is actually gripped by the user in the process of raising and lowering the lifting bar 61 and the weight 80. The knob member 65 has a rod- And is protruded outward in the transverse direction in a state of being integrally connected to one side of the surface.

With the structure described above, the pull member 65 is connected to the elevating bar 61 through the connecting member 63, and the pull member 65 is structured so that the pull member 65 can be lifted and lowered simultaneously with the vertical movement of the connecting member 63 .

In this state, the first fastening pin 66 is fastened to the connecting member 63 and the elevating bar 61 in a detachable manner.

The first fastening pin 66 serves to hold the changed position of the connecting member 63 and the pull member 65 in the ascending and descending processes and is formed in the form of a pin having a certain length The connection member 63 and the lifting bar 61 are formed of a metal such as a metal or a magnet, When the first fastening pin 66 passes through the first fastening hole 64 and the second fastening hole 62, the surface of the first fastening pin 66 is pulled by the self- And is attached to the rim of the hole 64 and the second fastening hole 62.

This prevents the first fastening pin 66 from being undesirably detached from the first fastening hole 64 and the first fastening hole, thereby preventing the connection member 63 from being raised or lowered unwantedly .

In this state, a ring-shaped rotation induction ring 70 having a lower end opened is connected to the lower end of the lifting bar 61 in a flange shape.

Further, in this state, a mounting hole 71 having a lower end portion is formed at a certain depth on the lower surface of the rotation inducing ring 70 at a central point.

Inside the mounting hole 71, an elastic member 72 in the form of a coil prism is inserted and installed in the mounting hole 71 while vertically contracting and acting in the direction of the elastic force.

In this state, a ball-shaped rotation control guide ball 73 is positioned at the lower end of the elastic member 72 in the installation hole 71, and a part of the upper end of the rotation control guide ball 73 is inserted into the installation hole 71 And the bottom portion of the elastic member 72 is protruded to the outside of the installation hole 71 to be exposed.

With this structure, when the rotation control guide ball 73 is pushed upwards, it is inserted into the installation hole, and at the same time, a force is exerted to cause the elastic control member 72 to spring back toward the lower side by the elastic force of the elastic member 72.

 In this state, a weight 80 is stacked on a lower portion of the lower end of the body 10 below the lower end of the lifting bar 61.

The weights 80 serve as weights for the bench press motion, and are in the form of blocks of rectangular parallelepiped and stacked in a state in which they are in close contact with each other.

A fastening protrusion 81 protrudes from a lower end of the lifting bar 61 and protrudes from a lower end of the lifting bar 61, And is then integrally fastened to the lower end of the lifting bar 61.

At the same time, the lower end surface of the rotation guide ring 70 is seated on the upper surface of the weight located at the uppermost point of the weight,

At this time, a rotation control guide groove 82 having a predetermined depth is formed at a vertically opposed position with respect to the rotation control guide ball 73 at the uppermost weight and the rotation control guide groove 82 is formed And arranged in a circular shape at intervals.

At this time, the rotation control guide groove 82 is formed in a hemispherical groove shape so that the lower point of the specific rotation control guide ball 73 is inserted when the rotation guide ring 70 is seated on the weight.

In this state, the rotation control guide ball 73 is inserted into the rotation control guide groove 82 while being pushed downward by the elastic force of the elastic member 72 inside.

With such a structure, when the user normally holds the knob member 65 by lifting the knob member 65, the weight bar 80 together with the lifting bar 61 can be raised and lowered to perform a typical bench press motion.

In this state, when the user narrows or increases the gap between the two knob members and eventually widens or narrows the gap between the user's arms, the user grips the knob member 65 to rotate the lift bar 61 forcibly The lifting bar 61 and the pulling member 65 simultaneously rotate about the fastening protrusion 81. In this process, the rotation control guide ball 73 inserted in the rotation control guide groove 82 is rotated by the rotation control And is pushed upwards in the process of moving to the other rotation control induction groove in the vicinity of the guide groove 82 so that the elastic member 72 inside is pressed.

The rotation control guide ball 73 smoothly moves out of the rotation control guide groove 82 and moves to the other rotation control guide groove 82 and is positioned on the other rotation control guide groove 82, 72 so as to be strongly fitted in the corresponding rotation control guide groove 82. [

Thus, the lifting bar 61 can be rotated stepwise by the distance between the formation of the respective rotation control guide grooves 82, so that the user rotates the lifting bar to eventually rotate the pulling member 65, Since the exercise can be performed in a state in which the distance between the arms is adjusted, the exercise effect according to the adjustment of the arm spacing can be obtained differently.

The rotation control guide ball 73 is strongly urged in the rotation control guide groove 82 by the elastic force of the elastic member 72 due to the structure between the rotation control guide groove 82 and the rotation control guide ball 73 The movement of the lifting bar 61 and the pulling member 65 is minimized and a force is applied when the lifting bar 61 and the pulling member 65 need to be rotated. As shown in Fig.

The rotating structure of the lifting bar is not limited to the above description and drawings and a plurality of holes 1 may be formed along the circumferential surface of the lifting bar 61 located inside the guide pipe 50 as shown in [ The auxiliary hole 2 may be formed in the circumferential point, and then may be connected to or separated from the hole and the auxiliary hole through a separate pin 3,

In this case, the lifting bar 61 can be freely rotated in the guide pipe 50 in a state where the pin 3 is separated, and can have a structure in which rotation is restricted when the pin is fastened.

The second fastening pin 40 is supported by the support tube 31 and the support bar 22 when the user intends to change the height of the seat by adjusting the height of the seat in the state in which the seat 20 is tilted by the user, When the rear end of the sheet 20 is lifted around the hinge 21, the supporting bar 22 is lifted together with the third fastening hole 23 facing the fourth fastening hole 23, The rising state of the rear end of the sheet 20 can be maintained by being inserted into the hole 32.

When the weight 65 is lifted up and down with both arms lying on the seat in this state, the weight 80 is moved up and down simultaneously with the lifting bar 61 to perform the movement.

In this case, when the user desires to change the distance between the arms to adjust the distance between the arms, as described above, when the user pulls the pull member 65 and forcibly rotates the lifting bar 61, The knob member 65 simultaneously rotates about the fastening protrusion 81. In this process, the rotation control guide ball 73 inserted in the rotation control guide groove 82 rides on the rotation control guide groove 82 And is pushed upwards in the process of moving to the other rotary control guide groove, thereby pressing the inner elastic member 72.

The rotation control guide ball 73 smoothly moves out of the rotation control guide groove 82 and moves to the other rotation control guide groove 82 and is positioned on the other rotation control guide groove 82, 72 so as to be strongly fitted in the corresponding rotation control guide groove 82. [

Thus, the lifting bar 61 can be rotated stepwise by the distance between the rotation control guide grooves 82 formed.

In this state, when the upper and lower positions of the pull tab 65 are to be adjusted according to the physical condition of the user or the like, the first fastening pin 66 is separated from the lifting bar 61 and the connecting member 63, The member 63 and the pull member 65 are lifted up and down along the vertical direction of the lifting bar 61 to be positioned at a proper position and the first fastening pin 66 is moved to the first fastening hole 64 and the second fastening hole 66 So that the adjusted position can be maintained by simultaneously inserting it into the fastening hole 62.

At this time, since the first fastening pin 66 and the second fastening pin 40 are both in the form of a magnet, a phenomenon of being easily and unwantedly inserted in the fastening holes can be prevented.
