Description

[Detailed explanation of the idea] "Industrial application field" The present invention relates to a baseball base.

``Prior Art'' There are many known examples of baseball bases (hereinafter simply referred to as bases), and generally, in order to prevent the base from moving during a game, the base is fixed to the ground by some means. There are many things to do. However, in so-called grass baseball and youth baseball, there is no problem even if the base moves slightly during the game, so there are proposals such as Utility Model Publication No. 58-18921 in which the base is simply placed on the ground.

``Problem that the invention attempts to solve'' However, the above-mentioned Utility Model Publication No. 18921/1989 has an anti-slip rib on the inside of the rubber inverted dish-shaped base body, the flat surface of which is in contact with the ground. Although it has a grid-like structure parallel to the outer edge of the base, it does have a certain anti-slip effect. When stepping on a base, the bases are not only subjected to external forces in a simple direction along the line connecting the bases, but are also often subjected to strong external forces from all directions, so they may violently move from their predetermined positions during the competition. Sometimes. Furthermore, the base disclosed in Japanese Utility Model Publication No. 18921/1989 does not have a means for fixing it to the ground, so it has the disadvantage that it cannot be used when playing a game with the base fixed to the ground.

The purpose of the present invention is to provide a new base that overcomes the drawbacks of the above-mentioned conventional techniques.

``Means for Solving the Problems'' The base of the present invention that achieves the above objectives is ``a plate-shaped periphery surrounded by a rectangular frame, and a plate-shaped periphery connected integrally with the plate-shaped periphery to cover the plate-shaped periphery. It consists of a base main body consisting of a plate-like upper surface portion and a non-slip rib provided inside the base main body, and the non-slip rib forms a plate-like body integrally connected to the base main body. The lower end is in contact with the ground, and the lower end is provided with a continuous locking pawl in the shape of a saw blade, and the anti-slip rib is generally parallel to a diagonal line of the base body and is shaped like a sash. Cross-arranged structure
is a feature.

``Function'' The base of the present invention, which is characterized by the above-mentioned structure, has a group of locking claws at the lower end of the anti-slip ribs arranged in a sash shape, which functions as a locking claw against the ground.
It has a strong anti-slip effect even when the base is subjected to external forces from all directions during competition.

"Example" Hereinafter, a detailed explanation will be given based on an example. Referring to FIG. 1 showing an embodiment thereof, the base of the present invention includes a plate-shaped peripheral edge 2 surrounded by a rectangular frame, and a plate-shaped upper surface portion that integrally covers the upper edge of the plate-shaped peripheral edge 2 in a mid-height shape. 3
It consists of a base body 1 having a. and,
The hollow part 4 inside the base body 1 is
Two plate-shaped partition ribs 5 that intersect at the center of
A and 5B are divided into four spaces 6A, 6B, 6C, and 6D of the same size with openings at the bottom, and these spaces 6A to 6D are equipped with sashes.
Plate-shaped anti-slip ribs 7A and 7B are provided which intersect in a shape, and the lower ends of the anti-slip ribs 7A and 7B have a continuous trapezoidal shape with a fine pitch P in the longitudinal direction, as shown in FIGS. 1F and G. Notches 8 are formed, and intermediate portions of adjacent notches 8 are formed into locking claws 9.

That is, the anti-slip ribs 7A and 7B are provided with the intention of preventing the base body 1 from slipping when an impactful external force is applied to the base body 1 from all directions. , the upper end and the side end are integrally connected to the plate-like upper surface part 3 and the plate-like peripheral edge 2, and the lower end in contact with the ground is formed into a saw blade-like continuous locking claw 9, and the space part 6A The anti-slip ribs 7A, 7B of -6D are generally parallel to the diagonal lines 10A, 10B of the base body 1. Note that the partition ribs 5A, 5B maintain the mechanical strength of the base body, partition the hollow portion 4, and provide a non-slip effect.
A locking pawl 9, which is the same as the anti-slip ribs 7A and 7B, is also provided at the lower end of B.

Further, in the middle position of each side of the plate-like peripheral edge 2 of the base body 1 of this embodiment, there is a recess 11 provided on the outer periphery, a fixing plate 12 that forms the bottom of the recess 11 and is in contact with the ground, and A base fixing part 14 is provided, which consists of a locking nail hole 13 extending through the base body 1, and when it is desired to completely fix the base body 1 to the ground, a locking nail 15 is inserted into the locking nail hole 13 from the outside of the base body 1. The base body 1 can be fixed to the ground by driving the base body 1 into the ground. Note that the base in this example is made of rubber.

Next, other embodiments of the present invention will be described with reference to FIGS. 2 to 4. First, in FIGS. 2 and 3, a semicircular notch 8' or a triangular notch 8'' is formed in the base body 1 having the same anti-slip ribs 7A and 7B as in the embodiment shown in FIG. This is an embodiment in which claws 9 are provided consecutively.

Further, in the embodiment shown in the fourth figure, the dividing ribs shown in the first figure are omitted, and the main anti-slip ribs 7'A, 7'B intersect in a "sash" shape along the diagonal line of the hollow part 4.
and auxiliary anti-slip ribs 7''A, 7''B intersecting in a "sash" shape are arranged in the four spaces partitioned by the main anti-slip ribs 7'A, 7'B, This is an embodiment in which the same locking pawls 9 as in the embodiment of FIG. 1 are provided at the lower ends of the main non-slip ribs 7'A, 7'B and the sub-slip non-slip ribs 7''A, 7''B.

According to the base of the present invention having the above configuration, the locking claw 9 at the tip is in contact with the ground, and the anti-slip ribs 7A, 7B are provided on the inside of the base body 1, and are parallel to the diagonal lines 10A, 10B of the base body 1. Therefore, when receiving an impactful external force from a runner or fielder during a competition, the 9 groups of locking claws of the anti-slip ribs 7A and 7B will
The individual free ends (tips) constitute elastic locking claws in contact with the ground, and play the effects of friction between the free ends and the ground, hooking the ground with the free ends, and biting into the ground, and the base This has the effect of strongly preventing the main body 1 from sliding due to external force. Since the 9 groups of locking claws are arranged parallel to the diagonal lines 10A and 10B, the above-mentioned effect is exerted no matter which direction the base body 1 receives an external force from the runner, etc. Even if the runner slips from the corner portion of the main body 1, it can be expected that the base will be prevented from slipping.

Furthermore, since the base of the embodiment shown in FIG. Part 1
It is sufficient to simply drive the locking nail 15 into the base 4, making it easy to completely fix the base, and there are two ways to use it: simply placing it on the ground or completely fixing it to the ground. It has a lot of versatility.

In the above-mentioned configuration of the present invention, the anti-slip ribs 7A and 7B do not need to be completely parallel to the diagonal line of the base body 1, but it is sufficient that they are arranged approximately parallel to each other so that the above-described effect can be expected.

"Effects of the invention" As explained above, the baseball base of this invention has
Even if it is simply placed on the ground, it has excellent anti-slip performance against external forces in all directions during a game, and has the effect of widely improving the convenience of baseball players.
