There is. However, these gloves have a flat structure that makes it difficult to insert your hand into them, and when you put them on, they do not fit your hand well, making it difficult to move your fingers, making them uncomfortable to wear, and reducing work efficiency. It was inferior. Therefore, in recent years, this kind of gloves has been developed in three-dimensional form, for example,
Various products have been devised, such as "synthetic resin sheet gloves" disclosed in Japanese Patent No. 3-219605. As shown in FIGS. 11 to 13, this "synthetic resin sheet glove (30) J" has a three-dimensional curved surface on the periphery of the synthetic resin sheet (31) on the inside of the hand. This is a synthetic resin sheet glove (30)J characterized in that a synthetic resin sheet (32) is welded to the palm side, that is, the palm side is a flat sheet (32) and the middle side is a convex shape. A three-dimensional curved sheet (31) is formed by welding their peripheral edges together.

(Problem to be Solved by the Invention) However, since this type of glove is certainly formed three-dimensionally, it is easy to insert the hand, and the fit when worn is different from that of the conventional flat structure. Although this was an improvement over the previous gloves, it was still not sufficient. This is because the palm of the hand is not necessarily flat, and a sufficient fit cannot be obtained, especially in the part of the hand that extends from the palm side to the middle of the hand, such as the fingers.

In addition, in this type of three-dimensional glove, the inside of the hand is a three-dimensional curved surface, and the palm side of the hand is flat, and the inside and palm sides of the hand are differentiated. Because there is
When wearing it, it was necessary to check the front and back sides, which was cumbersome.

The present invention was made in view of the above circumstances, and
The purpose is to provide three-dimensional gloves that provide a sufficient fit when worn and do not require checking the front and back sides when worn, as well as to provide a method for manufacturing the same. .

(Means for Solving the Problems) The means taken by the present invention to solve the above-mentioned problems are as follows. The gist of the present invention is a three-dimensional glove (10) J characterized in that the three-dimensional gloves (10) are welded to each other leaving the wrist portion (12), and the invention of claim 2 is a method for manufacturing this three-dimensional glove (10). The method adopted by ``3D gloves (10 ), wherein the two heat-melting flexible sheets (11aX11b) are superimposed to form a mold material (21) having a hand-shaped recess (22).
), and then, by ultrasonic vibration, the two heat-melting flexible sheets (11a) and (11b) are cut into a hand shape, and at the same time, the cut ends are welded to each other, leaving the wrist part (12). The gist of this paper is ``a method for manufacturing a three-dimensional glove (IO)'' characterized by the following.

(Function of the invention) By adopting the above-mentioned means, the three-dimensional glove (lO) according to claim 1 functions as follows. That is, by welding together two hand-shaped thermofusible flexible sheets (11a811b) having convex three-dimensional curved surfaces,
The three-dimensional glove (lO) has a convex shape on both the palm side and the middle side of the hand, making it easy to insert the hand and providing a good fit when worn. Since the sides also have a convex three-dimensional curved surface, there is no distinction between the palm side and the middle side, and there is no need to check the front and back when wearing it.

Further, according to the manufacturing method according to claim 2, two superimposed thermofusible flexible sheets (11a) (11b) are brought into close contact with the mold material (21) having the hand-shaped recess (22). , these sheets) (11aX11b) are cut into a hand shape using ultrasonic vibration, and at the same time, the cut ends are welded to easily form a three-dimensional glove (10), which has a convex three-dimensional curved surface on the palm side and the middle side. Furthermore, since the mold material (21) is formed in a concave shape, the mold material (21) can be made smaller compared to manufacturing a conventional flat glove (30). You can do this by
This also leads to downsizing of the manufacturing equipment itself.
