Description

本発明は、野球ベースに関する。より詳しくは、設置時に簡易な方法で地面に固定できる一塁、二塁及び三塁用の野球ベース(以下、本明細書において「野球ベース」は、一塁、二塁及び三塁の標識として用いられる野球ベースを指す。)に関する。   The present invention relates to a baseball base. More specifically, baseball bases for first base, second base and third base that can be fixed to the ground by a simple method at the time of installation (hereinafter, “baseball base” refers to a baseball base used as a sign for first base, second base and third base) .)

スポーツとしての野球は、日本、米国、韓国、台湾及びキューバを初め、多くの国、地域で親しまれている。
野球において、野球ベースは、地面に固定して用いられる。野球ベースが地面に固定された状態において、野球ベースは、地面から一定の厚みのある高さを有し、地面を鉛直方向から見下ろす角度からは1辺が350〜400mm程度の正四角形となる形状をしている。
Baseball as a sport is popular in many countries and regions, including Japan, the United States, South Korea, Taiwan and Cuba.
In baseball, a baseball base is used by being fixed to the ground. In a state in which the baseball base is fixed to the ground, the baseball base has a certain height from the ground, and is a square having a side of about 350 to 400 mm from the angle of looking down the ground from the vertical direction. I am doing.

野球のルールに従い、人間は、各塁を足で踏むか、体を地面に滑らせながら手で触ること等により、野球ベースに接触する。また、人間は、必要に応じ相手チームの人間より先に野球ベースに接触することを求められるため、全力で走りながら当該野球ベースを踏むこと、又は、スライディングにより野球ベースに接触すること等を行う。
そのため、野球ベースに加えられる衝撃は、大きいものとなり、野球ベースから人間に対して生じる衝撃も大きいものとなる。
人間から加えられる衝撃により野球ベースが定位置から移動しないため、野球ベースは、確実に地面に固定される必要がある。
According to the rules of baseball, a human touches the baseball base by stepping on each heel with his feet or touching his hand while sliding his body on the ground. In addition, since humans are required to contact the baseball base before the opponent team, if necessary, they step on the baseball base while running at full power, or contact the baseball base by sliding, etc. .
Therefore, the impact applied to the baseball base is large, and the impact generated from the baseball base to the human is also large.
Since the baseball base does not move from a fixed position due to an impact applied by a human, the baseball base needs to be securely fixed to the ground.

また、野球ベースとの接触時に人間が負傷しないようにするためには、野球ベースは、地面に固定されつつも、強い衝撃に対する一定の緩衝作用又は固定を開放する作用を有する必要がある。
また、グラウンドを有効に活用するため、野球用グラウンドとして使用する地面に対して野球ベースを簡便な方法で設置及び撤去を行う必要がある。
Further, in order to prevent human beings from being injured when contacting with the baseball base, the baseball base needs to have a certain buffering action against a strong impact or an action to release the fixing while being fixed to the ground.
In order to effectively use the ground, it is necessary to install and remove the baseball base with respect to the ground used as the baseball ground by a simple method.

固定機能付き野球ベースについては、安全に、かつ、確実に野球ベースをグラウンドに固定することができる固定機能付き野球ベースとして、グラウンドにアンカーボルトによって固定される固定部材と、この固定部材に被せるための凹部が底面に形成されたベース本体とから構成される固定機能付き野球ベースが知られている(特許文献1)。
しかし、上記文献記載の固定機能付き野球ベースでは、地面に対して垂直にアンカーボルトが挿入され、かつ複数のアンカーボルトが平行に固定されているため、人間が加える衝撃により、取付け部等を通じて野球ベースを固定しているアンカーボルトが地面から抜け出し、野球ベースが定位置から移動してしまうという問題があった。また、アンカーボルトが抜け出した場合、アンカーボルトの先端で人間が大きく負傷するという問題もあった。
Regarding the baseball base with a fixing function, as a baseball base with a fixing function that can safely and reliably fix the baseball base to the ground, a fixing member that is fixed to the ground by an anchor bolt, and a covering member that covers the fixing member There is known a baseball base with a fixing function that is composed of a base body having a concave portion formed on the bottom surface (Patent Document 1).
However, in the baseball base with a fixing function described in the above-mentioned document, the anchor bolts are inserted perpendicularly to the ground and the plurality of anchor bolts are fixed in parallel. There was a problem that the anchor bolt fixing the base slips out of the ground and the baseball base moves from a fixed position. In addition, when the anchor bolt is pulled out, there is a problem that humans are seriously injured at the tip of the anchor bolt.

また、特許文献2及び3では、裏面に多数の突起が設けられた野球ベースが開示されているところ、地面に対する固定は十分に強力なものではなく、また、地面の状態によっては、野球ベースの上面を地面に対して平行に固定することができず、却って不安定になってしまうという問題があった(特許文献2及び3)。   In Patent Documents 2 and 3, a baseball base having a large number of protrusions on the back surface is disclosed. However, fixing to the ground is not sufficiently strong, and depending on the state of the ground, the baseball base There was a problem that the upper surface could not be fixed parallel to the ground, and instead became unstable (Patent Documents 2 and 3).

In the fixing device 2, four bar-shaped parts 22 are respectively inserted into four guide holes 21 a provided in the fixing part 21, and one of the bar-shaped parts 22 is inserted into the ground 4. By being fixed to the ground.
A portion larger than the diameter of the guide hole 21a exists at the other tip of the rod-shaped component 22 that is not on the side to be inserted into the ground, thereby preventing the rod-shaped component 22 from being buried in the fixed component.

図2及び図3に示す通り、実施形態に係る野球ベース1においては、固定部品21が棒状部品22により地面4に固定された時に、棒状部品22の地面に挿入される側の先端位置を通る鉛直線と地面との交点4aが、棒状部品22と地面とが交わる領域(棒状部品22の差込位置)4bよりも、固定部品21の重心21bから遠い位置にある。   As shown in FIG. 2 and FIG. 3, in the baseball base 1 according to the embodiment, when the fixed component 21 is fixed to the ground 4 by the rod-shaped component 22, it passes through the tip position of the rod-shaped component 22 on the side inserted into the ground. The intersection 4a between the vertical line and the ground is located farther from the center of gravity 21b of the fixed component 21 than the region (insertion position of the rod-shaped component 22) 4b where the rod-shaped component 22 and the ground intersect.

図4中に示された棒状部品22’では、棒状部品22’の地面に挿入される側でない他方の先端は、ガイド穴21aの径よりも大きい部分がリング22’aとなり、棒状部品22’を引き抜くことを容易にしている。また、リング22’aとガイド穴21aによって位置決めされることにより、棒状部品22’の小径部分22’bは、使用時に地面付近に存在する。即ち、小径部分22’bは、小径部分22’bの位置で棒状部品22’が破断した時に、破断した棒状部品22’が、地面4又は固定部品21から突出しない位置に存在する。   In the rod-shaped component 22 ′ shown in FIG. 4, a portion larger than the diameter of the guide hole 21a is a ring 22′a at the other end of the rod-shaped component 22 ′ that is not inserted into the ground, and the rod-shaped component 22 ′. It is easy to pull out. In addition, the small-diameter portion 22'b of the rod-like component 22 'is located near the ground when in use by being positioned by the ring 22'a and the guide hole 21a. That is, the small-diameter portion 22 ′ b exists at a position where the broken rod-shaped component 22 ′ does not protrude from the ground 4 or the fixed component 21 when the rod-shaped component 22 ′ is broken at the position of the small-diameter portion 22 ′ b.

また、図4中に示された棒状部品22’では、強度が他の部分より相対的に弱い箇所として小径部分22’bが設けられ、棒状部品22’の他の部分から小径部分に向かって径が細くなるように丸みを帯びたテーパー状となっている。   Further, in the rod-shaped component 22 ′ shown in FIG. 4, a small-diameter portion 22′b is provided as a location where the strength is relatively weaker than other portions, and from the other portion of the rod-shaped component 22 ′ toward the small-diameter portion. It has a rounded taper shape so that the diameter becomes thinner.

本発明の野球ベースは、成人、少年を問わず、簡易式固定野球ベースとして好適に用いられる。   The baseball base of the present invention is suitably used as a simple fixed baseball base regardless of whether it is an adult or a boy.
