Abstract

The present invention relates to a structure in which a ring shaft of a separate pedestal and a bearing of a second pedestal are combined,
That is, with the ring shaft as the reference point,
Again, the second pedestal is provided to move only between the A and B supports.
Also, by using the center of gravity and the angle, the second pedestal is always centered toward the B pedestal so that the second pedestal is returned to the B pedestal.
Therefore, it is possible to move conveniently and safely by keeping the bar hanging bar which is disturbed in the range of movement within the range to the rear, thereby changing the angle of the bench press.

Description

{ANGLE OF ELEVATION TO THE BENCH PRESS}

The conventional bench press, which is a chest exercise device, has a fixed weight support,

The present invention relates to a bench press for changing the angle of a bench press so that the upper part of a weight support is moved by a predetermined angle so that a hook protruding above the weight support does not interfere within a movement range of motion, will be.

The weight support of the bench press, which is a chest exercise device, is fixed vertically or tilted backward.

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

The current bench press weights are either vertically fixed or tilted backwards.

Among them, the vertical type bench press is inconvenient because there is interference with the weight bar because the weight support hook part protrudes when the weight is lowered and the repetitive movement is performed.

In addition, the backward-type bench press has a problem in that it is used only by experts because it is unstable or dangerous because the center of the weight rod is shaken much while lifting the weight and bringing it to the center of the chest.

To achieve this object,

The present invention comprises a separate pedestal (50); A ring shaft 12 of the ring gear 12; And a second pedestal (20); A bearing case and a bearing 21; That is, the ring shaft 12; As a reference point,

Again, the second pedestal 20; An A support 100; And B support 200; Respectively.

And, a bench press 300 whose angle is changed; When not used,

The B support 200; The second pedestal 20; Respectively,

Here, the A support base 100; Is positioned at a predetermined angle less than an angle perpendicular to the ground,

The second pedestal 20; (100); The B support 200 at all times; The center is biased toward.

Therefore, the second pedestal 20; The B support 200; The A support 100 in the position; The second support base 20; Again

The B support 200; And is inclined backward.

The present invention is advantageous in that a novice user can easily use the second pedestal which is disturbed within the range of movement of motion, so that a beginner can easily use the pedestal, and when the repetitive exercise of lifting and lowering the weight rods is performed, It has an excellent effect in preventing a safety accident such as falling.
