Description

[Detailed Description of the Invention] This invention relates to an exercise aid, and more specifically, to an exercise aid that can perform rowing exercises in addition to pull-ups.

The first purpose of this invention is to provide an exercise aid that allows hanging exercise by folding the leg bars along the main frame.

The second purpose of this invention is to provide an exercise aid that allows rowing exercise by placing the leg bars in contact with the ground, and effectively trains the entire body, including the arms, abdominal muscles, back muscles, chest muscles, legs and hips. It is in.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the figure, the exercise aid includes a base 1, a main frame 2 erected on the base 1, a leg bar 3 attached to the bottom of the main frame 2 so as to be able to rise and fall freely, and a leg bar 3 attached to the leg bar 3. Seat member 4
and a handle frame 6 attached to the base 1 and connected to the seat member 4 by a connecting rod 5 in the middle.

The base 1 is formed by bending a pipe into a U-shape in plan, and the main frame 2 is fixed upright on both parallel parts 1a of the base 1.

The main frame 2 consists of pillars 7 erected on both sides of the base 1 and an upper frame 8 formed by bending a pipe downward in a U-shape. It becomes part 9, and the parallel rods 8a on both sides are inserted into the support column 7.

A set screw 10 is attached to the upper end of the support column 7, so that the height position of the upper frame 8 can be freely adjusted.

The leg rod 3 has two straight rods 11 and a grounding frame 12 bent into a pipe-like U-shape, with both ends inserted into and out of the straight rods 11 so as to be freely inserted and removed, and with parallel parts on both sides bent in the middle. The end of the straight rod 11 is pivotally attached to the lower part of the support 7 in the main frame 2 with a mounting bracket 13.

This leg bar 3 can freely rise and fall up and down around the pivot point to the main frame 2, and when the grounding frame 12 is brought into contact with the ground when lying down, the straight bar 1
1 protrudes in front of the main frame 2 in a horizontal state.

Further, when the straight rod 11 is erected along the support 7, the horizontal part of the grounding frame 12 becomes a grip part 14 for hanging the child.

The grounding frame 12 of the leg bar 3 is replaced so that the bending direction changes when standing up and when touching the ground, so that an adult can hang on the main frame 2 and a child can hang on the leg bar 3 at the same time.

The seat member 4 is placed on the straight rod 11 of the leg bar 3 that is laid down, and is attached to the straight rod 11 by wheels or guide fittings 15 so that it can move freely along the longitudinal direction of the straight rod 11. It is being

The handle frame 6 is formed by bending a pipe into a downward U-shape that is wider than the pusher frame 3, and both ends of the handle frame 6 are pivoted on the upper surface of the base 1 at a position forward of the main frame 2, and a lower end pivot portion is formed. It can swing freely back and forth around the center.

The back and forth swing of the handle frame 6 is transmitted to the seat member 4 through the connecting rods 5, and when the handle frame 6 is not in use, a set screw 16 is installed on both sides of its upper end in the middle of the support column 7 in the main frame 2.
It is now fixed by

The upright state of the push frame 3 is maintained by fixing the handle frame 6 to the main frame 2, as shown in FIG.

That is, the seat member 4 is suppressed rearward by the continuous rods 5 and fixed by the reinforcing rods 16 installed at the upper ends of the columns 7.

Further, at the bottom of the main frame 2, there is a belt 17 for hooking the toes during rowing, and at the bottom of this belt 17 there is a footrest 1.
8 is provided.

The exercise aid of this invention has the above-mentioned structure, and how to use it will be explained next.

First, in order to row the boat, as shown in FIGS. 1 and 2, the push frame 3 is grounded, the setscrews 16 are removed, and the handle frame 6 is released from the main frame 2.

In this state, as shown in FIG. 4, the user sits on the seat member 4 facing the main frame 2, grasps the upper horizontal part of the handle bar 6, and puts his/her feet on the footrest 18.

When the body is arched backwards while pulling the handlebar 6 backward, the seat member 4 is moved rearward by the handlebar 6, and the entire body becomes arched and the head lowers.

From this state, all you have to do is pull your body up while hooking your legs onto the belt 17 and push the handle bar 6 forward. By repeating this back and forth movement, you can strengthen your arms, abdominal muscles, back muscles, chest muscles, handstands, etc. Training can be done.

Next, in order to perform a suspension motion, tighten the handle frame 6 with the setscrew 1.
At 6, it is fixed to the main frame 2 and the push frame 3 is erected.

At this time, the grounding frame 12 on the push frame 3 is replaced so that the front and back sides are reversed.

In this state, as shown in FIG. 6, the child hangs from the grip part 9 of the main frame 2 and performs a pull-up, and the child can do a pull-up using the push frame 3.

As mentioned above, with this device, you can perform rowing exercises and pull-up exercises simply by manipulating the ups and downs of the leg bars, and can train your entire body including your arms, abdominal muscles, back muscles, chest muscles, handstands, and even your legs and hips. It is extremely versatile and can be used to straighten the back muscles, and it is easy to change.
It can have profound effects that contribute to health management.

Furthermore, the seat member and the handle frame are linked by a link, and the seat member is connected to the handle frame so that they move together in the direction of swing of the handle frame, ensuring the same movement as when rowing an actual boat. It becomes like this.
