Description

[Detailed description of the invention] Regarding the manufacturing method.

In general, training equipment used for muscle training, especially iron bells, have a color such as blue on the surface of the material, and the grip is simply wrapped with vinyl tape. there were.

As a result, the grip part often becomes slippery or sticky when used, which is often unpleasant, and it is also prone to rust if left unattended, so even if it is left indoors, there is a risk of accidental bumps. The risk was high.

Therefore, the present invention has been made with attention to this point,
A training device that eliminates slippage and stickiness on the grip part, has a cushioning surface, has an aesthetic appearance that can be placed indoors and can be used as interior decoration, and is also easy to clean. It provides a manufacturing method, the gist of which is that an adhesive layer is provided on the surface of the material, and synthetic fiber hairs are firmly implanted on the surface of the adhesive layer. The training equipment is characterized in that an adhesive is applied to the surface of the material, then fine piles of synthetic fibers are densely flocked vertically using electrostatic processing, and then the excess piles are removed by drying. It consists in the manufacturing method of training equipment.

Next, an example of implementation of the present invention will be described with reference to the drawings.

In the figure, reference numeral 1 indicates a dumbbell according to the present invention, and this dumbbell 1 is provided with an adhesive layer 2 on the entire surface, and a group of synthetic fiber hairs 3 is tightly fixed and implanted on the surface of the adhesive layer 2. , coated.

To manufacture a dumbbell l having such a structure, a string 5 is wound around the center of the grip 4 of the raw dumbbell l, and the string 5 is hung around the center, and adhesive is first applied to the surfaces of the positive parts 6 on both sides, and then the adhesive is applied. Before drying, piles made of synthetic fibers (mainly nylon) of a suitably selected color are sprayed using the cap 7 of an electrostatic processing machine. As a result of the blowing, the synthetic fiber pile is planted and fixed in a vertical position.

Thereafter, it is dried in a normal dryer at approximately 50 degrees Celsius for 30 to 60 minutes, and the pressure applied to the front portion 6 is temporarily terminated.

Next, the dumbbell l that has been processed into the regular portion 6@6 is placed on the stand 8, and processed into the grip 4 in the same manner as above while being rolled.

At this time, it goes without saying that the color of the pile on the grip 4 may be the same as that of the main portion 6, or may be a different color.

Thereafter, excess pile is removed using a bristle brush or the like, and final drying is performed at approximately 100 degrees Celsius for 3 to 5 minutes to obtain a product.

In this example, a bell was used, but it is natural that it can be applied to dumbbells, barbells, etc.
indicates core metal.

The present invention is constructed as described above.

The product has a beautiful appearance, as if it were entirely covered with high-quality velvet, and can be placed indoors and has a sufficient interior effect.

In addition, Gutsurip 4 eliminates slippage and stickiness, providing a refreshing feel when used, and even if it is left unused when not in use, it will be cushioned even if there is an accidental collision, reducing the chance of injury and preventing rust. It does not cause any stains and can be easily cleaned even if it gets dirty.

As described above, the present invention has many excellent advantages, and implementing the present invention has enormous practical value.
