Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a home base and a pitcher plate.

[0002]

[Prior art]

 A conventional home base used for baseball has a structure as shown in FIGS. 3 (A) and 3 (B). That is, the conventional home base 1 is configured by fixing a hard rubber base body 3 on a wooden base 2 with an adhesive or the like. The base 2 is embedded in the ground so that the surface of the base body 3 is exposed to the ground, so that the home base 1 is fixed.

As shown in FIGS. 4 (A) and 4 (B), the pitcher plate 4 has the same structure, and a hard rubber plate body 6 is fixed on a wooden base 5 with an adhesive or the like. The pitcher plate 4 is fixed by burying the base 5 in the ground.

[0004]

[Problems to be solved by the device]

 By the way, the home body 1 and the base body 3 of the pitcher plate 4 and the plate body 6 are more damaged than the bases 2 and 5 because they are stepped on the spikes. Therefore, in a structure such as the conventional home base 1 or the pitcher plate 4 in which the base body 3 and the plate body 6 are integrally fixed to the bases 2 and 5, the damaged base body 3 and the plate body 6 are replaced. At that time, even if the bases 2 and 5 were still in a sufficiently usable state, the whole had to be replaced, which was very uneconomical.

Further, in the conventional home base and pitcher plate, the thickness of the base cannot be changed, and bases having different thicknesses have been manufactured. The present invention has been made in view of the above circumstances, and provides an economical home base and pitcher plate in which only the base body and plate body that are severely damaged can be replaced and the thickness of the base can be freely changed. The purpose is to provide.

[0006]

[Means for Solving the Problems]

 For this reason, the home base of the present invention is configured such that the base body, the base, and the bases having substantially the same shape can be separably coupled by the coupling means, and the plurality of bases having substantially the same shape with respect to the base body. Is configured to be stackable. Similarly, in the pitcher plate of the present invention, the plate body, the base and the bases of substantially the same shape are separably fixed to each other by a coupling means, and a plurality of the substantially same shapes are attached to the plate body. The base is made stackable.

[0007]

[Action]

 According to the home base and the pitcher plate having such a configuration, the base body or the plate body and the base can be separated from each other, and when the base body or the plate body is damaged, only these can be replaced. Also, by stacking an appropriate number of bases of approximately the same shape and integrally fixing them to the base body or plate body, the thickness of the base portion can be easily changed. Eliminates the need to manufacture

[0008]

【Example】

 An embodiment of the home base according to the present invention will be described below with reference to FIG. 1 (A) to 1 (C), the home base 10 of the present embodiment is formed on a plastic base pentagonal base 11 with the same shape as the base 11 using hard rubber as in the conventional case. The base body 12 is fastened with bolts 13 as a coupling means to fix them.

The base 11 has bolt insertion holes 14 formed at appropriate locations (three locations in this embodiment). A recess 15 is provided at the end of the bolt insertion hole 14 on the bolt insertion side so that the head of the bolt 13 is flush with the base 11. Further, the recess 15 is formed in such a size that a sufficient clearance 16 is formed between the recess 15 and the head of the bolt so that a box spanner for tightening the bolt can be inserted therein.

The base body 12 is formed by embedding a nut 17 on the back surface side to which the base 11 is fixed. The home base 10 is fixed to each other by aligning the base body 12 on the base 11 and screwing the bolts 13 into the nuts 17 on the base body 12 side through the bolt insertion holes 14 of the base 11 to fix each other. Easy to assemble.

Then, as shown in FIG. 1C, another appropriate number of bases 11 having substantially the same shape are piled up by stacking an appropriate number (the number is not limited to this number in the present embodiment). If fixed, the thickness of the base can be easily changed. In this case, needless to say, it is necessary to use a bolt having a length that matches the thickness of the base portion. An adhesive may be applied between the bases 11 of each other.

According to the home base 10 having such a configuration, the base main body 12 and the base 11 can be easily separated by removing the bolts 13. When the base main body 12 is damaged, only the base main body 12 can be separated. Can be replaced. Further, by stacking an appropriate number of bases 11 having the same shape, the thickness of the base can be freely changed, and the bases having the same shape may be manufactured.

Therefore, when the base body 12 needs to be replaced, the base that does not need to be replaced can be used as it is, and there is no need to manufacture a base having a different thickness as in the conventional case. It is extremely economical and the manufacturing cost can be reduced. Next, the pitcher plate of the present invention will be described with reference to FIGS.

In FIG. 2, the pitcher plate 20 of this embodiment is similar to the home base 10 and is formed of hard rubber in the same shape as the base 21 on a plastic rectangular base 21. The plate body 22 is fastened with bolts 23 as a coupling means to fix them. The base 21 has bolt insertion holes 24 formed at appropriate locations (two locations in this embodiment). As with the home base 10, the bolt insertion side end of the bolt insertion hole 24 is provided with a recess 25 having a size such that a gap 26 is formed between the bolt insertion hole 24 and the head of the bolt.

A nut 27 is embedded in the plate body 22. Like the home base 10, the pitcher plate 20 can also be easily assembled by aligning the plate main body 22 on the base 21 and fixing each other with the bolts 23. In addition, the thickness of the base portion can be easily changed by stacking and fixing another appropriate number of bases 21 having substantially the same shape as shown in FIG. 2C. Also in this case, an adhesive may be applied between the bases 21.

The pitcher plate 20 having such a structure also has the same effect as the home base 10 as compared with the conventional pitcher plate. The structure for connecting the base body or plate body to the base or the bases is not limited to the bolts of this embodiment, and for example, a concave portion or a convex portion is formed on the base body or plate body side. It is also possible to provide a convex portion or a concave portion on the base side so as to correspond to a concave portion or a convex portion on the base body or plate main body side, and to couple the both by fitting the concave portion and the convex portion to each other. . The same applies to the mutual bases. In addition, a guide groove is provided on the side surface of the base body or plate body, and a guide part that slides freely into the guide groove on the base body or plate body side is provided on the base side to connect them. May be The same applies to the mutual bases. In this case, the guide groove may be provided on the base side and the guide portion may be provided on the base body or the plate body side. The base body or plate body and the base and the means for connecting the base to each other are not limited to the above-mentioned structures, and any structure can be used as long as the two can be firmly connected to each other.

[0017]

[Effect of device]

 As described above, according to the home base and the pitcher plate of the present invention, the base portion and the main body portion are configured to be separable, so when the main body portion is damaged and needs to be replaced, only the main body portion is replaced and the base portion is replaced. Since it can be used as it is without replacement, it is extremely economical and has a great resource saving effect. Also, the thickness of the base part can be freely changed by stacking an appropriate number of bases, so it is not necessary to manufacture bases of different thicknesses, and it is sufficient to manufacture bases of the same shape. Can be reduced.
