Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a core built into a baseball glove, and more specifically, the invention relates to a core body built into a baseball glove. To provide a baseball glove with a structure that restricts the thumb of the baseball glove from bending outward due to the impact of catching a ball while promoting inward bending, thereby making the ball catching operation more reliable. The purpose is to provide a core body.

[Conventional technology]

Conventionally, core bodies for baseball gloves have been designed to limit the outward bending of the thumb and encourage inward bending when catching a ball, such as the one devised in Japanese Utility Model Publication No. 55-51675. is publicly known.

According to this invention, a semi-hard material such as plastic is formed into a spoon shape, and this is built into the thumb pocket of the glove as a thumb-shaped core. However, in the conventional product described above, the core is made of a single piece, and the top of the core is formed into a curved shape, just like a spoon, and the direction of bending is limited by the curved shape. Therefore, when catching a hard ball that is heavy and has a speed of over 100 km/s, there is no problem when catching the ball accurately with the pocket of the glove, or when the ball hits the thumb directly. In this case, a ball pressure above a certain level is generated in such a part, and the core body cannot resist the ball pressure and is forced to bend outward, especially when the bending is suppressed by a curved structure like this. In this case, once bending in the opposite direction is allowed, cracks will occur in the curved portion, which will significantly reduce the resistance to bending outward, and the intended purpose may be lost. Furthermore, those made of a single plate have a limited durability against bending due to repeated ball catching, and have the disadvantage of prematurely ending their service life.

[Problem that the invention attempts to solve]

Therefore, the present invention solves the above-mentioned defects of the conventional products, further strengthens the durability of the core itself, and further effectively limits bending of the core in a certain direction. It is something that

That is, the present invention combines two long cores a and b made of synthetic resin plates, one of which has a plurality of protrusions 1 at appropriate intervals in its longitudinal direction. The other core body b is provided with a through hole 2 into which each protrusion 1 provided on one core body a is fitted, and the other core body b is provided with a transparent hole 2 provided at least at its upper end. Hole 2
has an opening somewhat larger than the protrusion 1 into which it is fitted, and when these two core bodies a and b are combined, a gap 3 is created at the lower edge of the fitting part between the protrusion 1 and the through hole 2. This is a core body for a baseball glove having a typical configuration.

〔Example〕

The present invention will be explained with reference to the drawings. The drawings show typical embodiments of the core body of the baseball glove of the present invention. 1 is a plan view and a side view showing one core body a formed in a circular shape, and the core body a has protrusions 1 formed at approximately equal intervals in its longitudinal direction. Next, FIG. 2 shows a plan view and a cross-sectional view of the other core b, which is formed to have a substantially similar shape to the one core a, and the core b is formed on the one core a. A through hole 2 is formed into which each of the protrusions 1 is fitted. The core body b may be made of the same material as the one core body a, or of course may be made of another same material. Next, FIG. 3 is a plan view and a cross-sectional view showing a state in which the core bodies a and b are combined and connected, and the fitting part of the protrusion 1 and the through hole 2 of both core bodies a and b is shown at the upper side. A gap 3 is formed at the lower edge of the fitting portion at two locations. Next, FIG. 4 is a perspective view showing a state in which the core bodies a and b are bent inward in a combined state.

That is, in the present invention, as shown in FIG.
When this is pushed and bent inward, the protruding part 1 protruding from the core body a moves downward according to the bending, and the width of the gap 3 created at the fitting part with the other core body b Only this makes it possible to move inward (bend). In other words, the width of the gap 3 in the fitting portion of the cores a and b is the permissible range for bending one of the cores a. Therefore, on the contrary, the outward bending of the core body a prevents the upward movement of the protruding part 1, since the fitting part with the core body b is in a sealed state with no gap at its upper side. , the outward bending of the core body a is limited by the mouth edge 5 on the upper side of the through hole 2. The core bodies a and b are provided with a protrusion 6 and a hole 7 for locking the two to further strengthen the bonding force between the two.

[Effects of the present invention] Therefore, according to the present invention, since the core bodies a and b are composed of two synthetic resin plates, the durability against bending is further strengthened and the usable life is maintained for a long time. Moreover, the bending can be reasonably restricted by using a flat plate, and the sizes of the protruding parts 1 and the through holes 2 of the core bodies a and b, as well as the width and position of the gap 3 created at the fitting part of both, can be varied. By forming this, the size and position of the bend can be changed freely, so by incorporating this into the glove, it is possible to obtain a glove with the desired function, which improves the ball-catching function inherent in a baseball glove. This can make a major contribution.

[Another example]

Figures 5 to 5 show core bodies a and b according to other embodiments.
When the protruding part 1 provided on one core body a is built into the thumb part of a baseball glove, a hollow part 4 through which the tightening cord is inserted is provided to form a cylindrical shape, and the protruding part 1 is made into a cylindrical shape. Part 1 and through hole 2 into which it fits
indicates a longer hole with an elongated hole. Of course, the protruding part 1 and the through hole 2 can be formed into a core body a having a desired bend by arbitrarily selecting the size, shape, and width of the gap 3 formed in the fitting part in addition to those shown in the embodiment. b can be obtained.

Therefore, as mentioned above, the present invention has extremely high practical value as a core body built into a baseball glove.
