Description

  The present invention relates to a torso for a kendo armor, and more particularly to a torso for a kendo armor for protecting the chest and torso of a kendo during a kendo game or practice.

  In general, armor for kendo consists of a “face” that protects the head and face, a “hand” that protects the wrist, a “torso” that protects the chest and torso, and a “slip” that is placed around the waist and hips. Such kendo armor is used to protect the kendo from injury during a kendo match or practice, but is particularly “mohamed” (ie, a bamboo stab site, eg, heart, wrist or neck). ) And crotch are protected.

  The “body” that protects the chest and torso is divided into a body that is a hard shell-like part of the abdomen and a “body” that is a part made of cloth or leather at the chest. At this time, the trunk is roughly divided into a bamboo trunk, a fiber trunk, and a synthetic resin trunk.

  Bamboo trunks are manufactured by traditional manufacturing methods. As shown in FIG. 1, bamboo pieces 21, 22, 23, and 24 are connected. The connected bamboo pieces are covered with leather and then coated with a black coating liquid and fixed. Such a bamboo trunk 10 'absorbs the impact of the bamboo sword very efficiently, but the product is very expensive, and there is a breakage that leather and bamboo are separated due to frequent impact and vibration. There are some problems that it is difficult to hold because it is sensitive to moisture. For reference, the leather attached to the outer surface of the trunk is not shown in FIG. 1 to clearly show the structure of the connected bamboo pieces 21, 22, 23, 24 of the trunk 10 '.

  Further, as shown in FIG. 2, a synthetic resin trunk and a fiber trunk, which are cheaper than a bamboo trunk, are widely used. The synthetic resin body base 10 'can be easily manufactured by injection processing of synthetic resin. However, the synthetic resin trunk is also heavy because the synthetic resin plate 30 is thick, and it cannot effectively absorb or reduce the shock and vibration generated when hit with a bamboo sword. There are several problems such as the point of impact and the color and picture painted on the front of the plastic part being easily peeled off.

  On the other hand, in order to solve the above-mentioned problems, Utility Model Document 1 “Kendo Clothing Chest Protection Plate” is disclosed. In Utility Model Document 1, the trunk is formed of a synthetic resin, and the corners are tied with a synthetic leather fastening string having a good cushioning force so as to improve safety and durability. Furthermore, the manufacturing cost of the breast protection plate can be reduced so that it can be easily manufactured.

However, this chest protection plate also has several problems, such as a heavy weight and a shock applied to the human body because it cannot sufficiently absorb or reduce the shock and vibration generated when a bamboo sword is hit. .

The present invention has been made to solve the above-mentioned problems, and has an object of having a thin plate made of synthetic resin, provided at the front and the rear, and a buffer layer between the front and back plates. It is intended to provide a comfortable body that is light and completely absorbs external shocks and vibrations.

  Another object of the present invention is to include a buffer layer between the front plate and the back plate. The first buffer layer is cut in the vertical direction, the second buffer layer is cut in a lattice shape, and the third buffer layer is cut in the vertical direction. To provide a kendo armor base that cuts through and forms a hole, thereby absorbing and mitigating shocks and vibrations more effectively than conventional bamboo and plastic bases. To provide shock and vibration isolation.

  Yet another object of the present invention is to provide a transparent, different from a conventional body made of an opaque synthetic resin for attaching various patterns, pictures and / or colors to the inner surface of the front plate or screen printing. Or to provide a kendo armor base made of a translucent synthetic resin, thereby preventing various patterns, pictures and / or colors from being peeled off or damaged by the impact of bamboo swords. Is.

  The trunk of the kendo armor of the present invention has a three-layer structure in which a buffer layer, which is a foam foam sheet, is inserted between the front plate and the back plate. Therefore, the body of the kendo armor of the present invention absorbs and relieves shocks and vibrations more completely than the bamboo body, provides an excellent shut-off force and is thin and provides good comfort, and is inexpensive.

  The trunk base according to the present invention is formed in the order of the front plate, the buffer layer, and the back plate as viewed from the outside so as to completely absorb external shocks and vibrations.

  The front plate can be adjusted to a single-layer structure, a double-layer structure, or the like as required. The front plate and the back plate can be made of polyethylene (PE, particularly HDPE), polypropylene (PP), polycarbonate (PC), polyethylene terephthalate ( It is made of any one selected from PET) and polyamide (PA and nylon).

In order to absorb and mitigate external shocks and vibrations from bamboo swords more completely, and to improve the shielding force against external shocks and vibrations, the buffer layer is made of foamed foam sheet and is used in the vertical direction. The first buffer layer is cut, the second buffer layer is cut in a lattice shape, and the third buffer layer is cut in the vertical direction and has holes at regular intervals. Here, the buffer layer has a single-layer structure, a two-layer structure, or a three-layer structure as necessary. Furthermore, the incision direction and the hole formation of each buffer layer may be changed. The foamed foam sheet of the buffer layer is made of any one selected from low density polyethylene (LDPE), ethylene vinyl acetate copolymer resin (EVA), polystyrene (PS), and polypropylene (PP).

  The manufacturing process of the trunk of the kendo armor of the present invention will be described below.

The manufacturing process of the body of the kendo armor of the present invention includes the following steps. That is, a transparent, translucent or opaque flat panel made of synthetic resin is cut into a front plate and a back plate by a cutting press.
Make holes in the front and back plates (to peel off the edges and torso the top of the trunk). In order to make the front plate and the back plate into a rounded curved surface, the front plate and the back plate are pushed out by putting them in a mold of a vacuum compression molding machine.
Then, various pictures and patterns are screen-printed on the inner surfaces of the transparent and translucent synthetic resin front and back plates. Each buffer layer is put into a cutting machine, cut in a vertical direction, a lattice shape, or a vertical direction and cut into a hole or a pattern. Thereafter, the buffer layer is coated with an adhesive, placed between the front plate and the back plate, firmly bonded with a compression press and processed.

As mentioned above, the body of the kendo armor according to the present invention is a molded product made of synthetic resin, so it is not handmade made by connecting bamboo pieces in a traditional manner, so it is low in price and has a bamboo sword. Can effectively absorb and reduce shocks and vibrations generated by Furthermore, the present invention uses a thin plate made of synthetic resin instead of a bamboo plate, and provides a light and comfortable comfort. In addition, the buffer layer is formed at regular intervals so that the first buffer layer cut vertically, the second buffer layer cut in a lattice shape, and cut vertically to completely absorb external shock and vibration. Since it has a third buffer layer with a perforated hole, the present invention can completely reduce impact and provides excellent shielding against impact. Also, printed layers of various patterns, pictures and colors are bonded or screen-printed on the inner surface of transparent or translucent front plates, and the torso of the kendo armor according to the present invention has a clean appearance that does not peel off paint or pictures. Can be kept.

  Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
