Description

[Detailed description of the invention] This invention relates to a training device (chest machine) for training arm strength and leg strength.

Next, this invention will be explained with reference to illustrated embodiments.
In the figure, 1... is a weight, which is a substantially rectangular and relatively thin plate-shaped body as shown in Figure 3, and has a hole 1a in the center for passing the hanging rod 2, and guides in the center of both sides. U-shaped notch 1 for passing the rods 3, 3 through
b, 1b. Weight 1... is guide rod 3,
A large number of pins 3 are stacked in the height direction, and the retaining pins 4 inserted into the desired number of pins from above are attached to the hanging rod 2.
It is designed so that it can be hung by passing it through the recess 2a.

The hanging rod 2 is suspended from a hanging frame 5 that can be raised and lowered along guide rods 3, 3. A rope 7 is wound around a guide rope wheel 6 of the hanging frame 5. The guide rods 3 of the weights have their lower ends fixed to the bottom frame 8, their upper ends fixed to the top frame 9, and are arranged vertically in parallel. Note that two sets of weights 1 and related items are installed so as to be used for both hands and both feet of the user, respectively. bottom frame 8
The top frame 9 is rigidly connected at its four corners by pillar members 10, and forms a box-shaped frame frame.

One side of the rope 7 wound around the guide rope wheel 6 of the hanging frame 5 is arranged via a guide rope wheel 11 attached to the front part of the top frame 9, and a chest weight handle 12 is attached to the upper end of the rope 7. are connected. The other side of the rope 7 is also the top frame 9
The lower end of the guide rope wheel 13 attached to the front part of the guide rope wheel 11 and the guide rope wheel 14 attached to the bottom frame 8 directly below the guide rope wheel 13 and the guide rope wheel 14 attached to the bottom frame 8 directly below Retsuguchiest 15 is attached to the part.

In the figure, 16 is the handle 1 for the chest weight.
This is a user's back or stomach pad installed at an intermediate location between the leg chest 15 and the leg chest 15. As shown in FIG. 1, this is a U-shaped overhanging frame 18 that is fixed so as to protrude an appropriate dimension forward from a stud 17 that is erected between the bottom frame 8 and the top frame 9 and approximately in the center of the front part. The device is fixed and installed at a height above the user's lower abdomen or at a height that touches the entire back of the user, tilting forward at a constant angle.

In the figure, reference numeral 19 denotes leg rests, which are installed on both sides of the overhanging frame 18, with support shafts 20 fixed at a height above the user's knees.

Next, to explain how to use this training device, as shown in Fig. 2 showing two exercise postures (a) and (b), the user stands facing forward in front of the abdominal pad 16 and leg pad 19, with both feet. A posture of wearing the leg chest weights 15, 15 around the neck and grasping the chest weight handles 12, 12 with both hands,
Postures are broadly classified into two: standing backwards, wearing leg chests on both ankles, leaning back on the back pads 16, and grasping the handles 12, 12 for the chest weights with both hands.

Therefore, according to the present invention, in any of the above usage modes, the user pulls the chest weight handle 12 and the leg chest weight 15 with the power of both hands and feet, and then lifts the common weight 1. By doing so, you can improve the effectiveness of your training, focusing on arm strength and leg strength, and ultimately train the muscle strength of your entire body. Additionally, since the pair of left and right ropes can be moved independently, it is possible to train the arms and legs separately on the left and right as a pair, which has the effect of increasing muscle strength in areas that cannot occur when training the left and right at the same time. play.

In addition, in the structure of this invention, the term "rope" includes chains, cables, cords, etc. in addition to the original rope with high tensile strength, and therefore, the term "rope vehicle" refers to chain vehicles, cable guide vehicles, pulleys, etc. It has a meaning that includes.

Claims (1)

[Scope of utility model registration request] A chest weight handle is attached to one end of each of a pair of left and right ropes that suspend weights via a guide rope wheel, and a leg chain is attached to the other end. This is a chest machine for strength training which is provided with fixed abdominal pads and leg pads that also serve as pads.
