Description

[Detailed description of the invention] This invention relates to the improvement of a muscle-strengthening device mainly used for the purpose of training and strengthening grip strength, and in particular, it relates to a grip-strength strengthening device that can be attached to the handle of a bag, etc. It is something.

Various devices for training grip strength have been known for a long time, such as a pair of grip handles arranged side by side at a predetermined distance and each made of a plate spring or coil spring so as to fit in the palm of the hand. It is attached to both ends of a compression spring, or the published utility model
As disclosed in Japanese Patent No. 6655, a large number of plate-shaped weights are stacked on a frame and connected to the shaft rod via pins, and a grip section is provided at the upper end of the shaft rod, and a grip section is provided above the shaft rod. A finger rest was formed on the frame, and by placing the thumb on the finger rest and the other fingers on the grip part, the weight was raised or lowered using a shaft rod.

By the way, although conventional devices of this kind are convenient for training grip strength, they cannot be attached to the handle of a bag that is carried around on a daily basis, or can not be used to train grip strength while being attached to this handle.

Focusing on this point, the present invention can be attached to the handle of a bag, bag, etc. that office workers, students, etc. carry on a daily basis while commuting to work or school, and can be used to train grip strength while attached to the handle. It is constructed so that it can be carried out without any trouble, and it is designed to be securely attached to the bag so that it is difficult to separate from the bag during use, while also being able to be easily attached to and removed from the bag. .

The present invention will be explained in detail below based on the illustrated embodiments.

In FIG. 1, the symbol C indicates a school bag, bag, etc., and the symbol S indicates a handle or strap attached to the top of the bag.

Reference numeral 1 denotes a grip strength strengthening tool of the present invention, 2 and 3 a pair of grip handles in the strengthening tool, which are arranged at a certain interval so as to fit in the palm of the hand, and 4 one of the grip handles (in the figure). This is a clamping plate attached to the back side of the lower grip handle.

The lower surface 5 of the holding plate 4 may be provided with a groove 6 into which the handle S can be inserted.

Reference numeral 7 extends through the clamping plate 4 and connects the pair of grip handles 2.
and 3, one end of which is fixed to the grip handle 2, and the other end is slidably attached to the other grip handle via the connecting rod fitting hole 8.

Incidentally, 9 is a stopper provided on the connecting rod 7.

Further, reference numeral 10 denotes a compression coil spring compressed around the connecting rod 7 and between the grip handle 2 and the clamping plate 4, and one end of this spring is in contact with the back surface of the clamping plate 4 as shown. The clamping plate is always pressed toward the grip handle 3 by the elastic force of the spring 10.

In addition, when fitting the bag handle between the grip handle 3 and the clamping plate 4 of the present invention, or when removing this handle,
As shown in FIG. 3, the grip plate 4 may be pushed up against the elasticity of the spring 10, and then the handle S may be inserted between the grip handle 3 and the grip plate 4, or removed from there.

As mentioned above, the grip strength strengthening device of the present invention can be attached to the handle of a bag, bag, etc. that you carry when commuting to work or school, traveling, shopping, etc. With the present invention, it is possible to train and strengthen grip strength while carrying the bag.

With the conventional type, it was completely impossible to use it if your hands were occupied with carrying a handbag, etc., which naturally limited the space and time you had to train your grip strength.

According to the civil engineering idea, the handle of a bag or the like is sandwiched between a clamping plate and a grip handle, and the clamping plate is pressed by the elasticity of a compression spring to strongly tighten the handle. There is no risk that the handle will separate from the device during use, and the present invention can be easily attached to the handle of a bag or the like by simply raising and lowering the clamping frame against the elasticity of the compression spring. , can be removed.

Furthermore, in the present invention, since the spring is only pressed against the clamping plate, it is easy to adjust the distance between the clamping plate and the grip handle, and it is easy to adjust the distance between the clamp plate and the grip handle. This has the practical effect of being able to be easily and reliably attached to the handle.
