しかしながら、上述の図６の従来のホールキャップにおいては、梁要素３２−１、３２−２、３２−３、３２−４に装着する際の入口側の各対のばね部材１２−１ａ、１２−１ｂ；１２−２ａ、１２−２ｂ；１２−３ａ、１２−３ｂ；１２−４ａ、１２−４ｂの距離Ｄ３（＝Ｄ１）は小さいので、対面したばね部材１２−１ａ、１２−１ｂ；１２−２ａ、１２−２ｂ；１２−３ａ、１２−３ｂ；１２−４ａ、１２−４ｂを係止ユニット３の梁部材３２の各梁要素３２−１、３２−２、３２−３、３２−４に装着する際に対面したばね部材１２−１ａ、１２−１ｂ；１２−２ａ、１２−２ｂ；１２−３ａ、１２−３ｂ；１２−４ａ、１２−４ｂが各梁要素３２−１、３２−２、３２−３、３２−４から僅かでもずれると、ばね部材１２−１ａ、１２−１ｂ；１２−２ａ、１２−２ｂ；１２−３ａ、１２−３ｂ；１２−４ａ、１２−４ｂの先端部が各梁要素３２−１、３２−２、３２−３、３２−４と衝突して装着しにくくかつ変形するという課題がある。 However, in the conventional hole cap of FIG. 6 described above, each pair of spring members 12-1a, 12- on the inlet side when attached to the beam elements 32-1, 32-2, 32-3, 32-4. 1b; 12-2a, 12-2b; 12-3a, 12-3b; 12-4a, 12-4b has a small distance D3 (= D1), so the facing spring members 12-1a, 12-1b; 12- 2a, 12-2b; 12-3a, 12-3b; 12-4a, 12-4b to the beam elements 32-1, 32-2, 32-3, 32-4 of the beam member 32 of the locking unit 3. Spring members 12-1a, 12-1b; 12-2a, 12-2b; 12-3a, 12-3b; 12-4a, 12-4b, which face each other when mounted, are beam elements 32-1, 32-2. , 32-3, 32-4, a slight deviation from the spring member 12-1a, 2-1b; 12-2a, 12-2b; 12-3a, 12-3b; 12-4a, 12-4b have tip portions of the beam elements 32-1, 32-2, 32-3, and 32-4. There is a problem that it is difficult to install due to a collision and is deformed.

他方、上述の対面したばね部材１２−１ａ、１２−１ｂ；１２−２ａ、１２−２ｂ；１２−３ａ、１２−３ｂ；１２−４ａ、１２−４ｂと係止ユニット３の梁部材３２の各梁要素３２−１、３２−２、３２−３、３２−４との衝突を避けるために、各対の対面したばね部材１２−１ａ、１２−１ｂ；１２−２ａ、１２−２ｂ；１２−３ａ、１２−３ｂ；１２−４ａ、１２−４ｂ間の入口側の距離Ｄ３を大きくすると、各対の対面したばね部材１２−１ａ、１２−１ｂ；１２−２ａ、１２−２ｂ；１２−３ａ、１２−３ｂ；１２−４ａ、１２−４ｂ間の距離Ｄ１、Ｄ２も通常大きくなる。この結果、梁要素３２−１、３２−２、３２−３、３２−４に装着されたばね部材１２−１ａ、１２−１ｂ；１２−２ａ、１２−２ｂ；１２−３ａ、１２−３ｂ；１２−４ａ、１２−４ｂの把持力が低下して梁要素３２−１、３２−２、３２−３、３２−４が外れ易いという課題がある。 On the other hand, each of the above-mentioned facing spring members 12-1a, 12-1b; 12-2a, 12-2b; 12-3a, 12-3b; 12-4a, 12-4b and the beam member 32 of the locking unit 3 In order to avoid collision with the beam elements 32-1, 32-2, 32-3, 32-4, each pair of facing spring members 12-1a, 12-1b; 12-2a, 12-2b; When the distance D3 on the inlet side between 3a, 12-3b; 12-4a, 12-4b is increased, the spring members 12-1a, 12-1b; 12-2a, 12-2b; 12-3b; distances D1 and D2 between 12-4a and 12-4b are also usually increased. As a result, the spring members 12-1a, 12-1b; 12-2a, 12-2b; 12-3a, 12-3b; 12 attached to the beam elements 32-1, 32-2, 32-3, 32-4. -4a, 12-4b has a problem that the gripping force is reduced and the beam elements 32-1, 32-2, 32-3, and 32-4 are easily detached.

上述の課題を解決するために、本考案に係るホールキャップは、開口を有し、開口を横切る梁部材を有する係止ユニットの開口を塞ぐためのホールキャップであって、開口より大きい平坦部材と、平坦部材の一面に固定され、梁部材を把持するための少なくとも１対の対面したばね部材とを具備し、１対の対面したばね部材の先端部は外側へ湾曲されて折り返されているものである。 In order to solve the above-mentioned problems, a hole cap according to the present invention is a hole cap for closing an opening of a locking unit having an opening and having a beam member crossing the opening, and a flat member larger than the opening. And at least one pair of facing spring members fixed to one surface of the flat member for gripping the beam member, and the tip portions of the pair of facing spring members are bent outward and bent back It is.

本考案によれば、１対の対面したばね部材の先端部は外側へ湾曲して折り返されているので、当該１対の対抗したばね部材間の入口側距離は実質的に大きくなる。従って、１対の対面したばね部材が多少ずれてもばね部材の先端部と梁部材との衝突を回避でき、梁部材の中心が１対の対面したばね部材の先端部の湾曲中心間であれば、梁部材がばね部材間に滑るように入り込む。この結果、梁部材の装着が容易となると共に、ばね部材の変形を防止できる。他方、当該１対の対面したばね部材間の梁部材を把持する第１の場所及び第１の場所隣接した第２の場所での距離を小さく維持すれば、梁部材に対する把持力の低下はなく、従って、一旦把持された梁部材は外れにくい。 According to the present invention, since the tip portions of the pair of facing spring members are bent outward and bent, the distance on the inlet side between the pair of opposed spring members is substantially increased. Therefore, even if the pair of facing spring members are slightly displaced, collision between the tip of the spring member and the beam member can be avoided, and the center of the beam member should be between the curved centers of the tip of the pair of facing spring members. For example, the beam member slides between the spring members. As a result, the beam member can be easily mounted and the spring member can be prevented from being deformed. On the other hand, if the distance between the first location for gripping the beam member between the pair of facing spring members and the second location adjacent to the first location is kept small, there will be no reduction in gripping force on the beam member. Therefore, the beam member once gripped is not easily detached.

That is, the distance D1 between the spring members 12'-1a and 12'-1b facing each other at the place where the beam element 32-1 is gripped is designed to match the diameter (size) of the beam element 32-1. The distance D2 between the facing spring members 12'-1a, 12'-1b in the place adjacent to the place where the beam element 32-1 is gripped is slightly smaller than the distance D1 (D2 <D1). The gripped beam element 32-1 is prevented from being detached.

図２は本考案に係るホールキャップの第２の実施の形態を示し、（Ａ）は底面図、（Ｂ）は側面図である。図２においては、図１の対面したばね部材１２’−３ａ、１２’−３ｂ；１２’−４ａ、１２’−４ｂを削除してある。つまり、２対の対面したばね部材１２’−１ａ、１２’−１ｂ；１２’−２ａ、１２’−２ｂのみを設ける。 2A and 2B show a second embodiment of a hole cap according to the present invention, in which FIG. 2A is a bottom view and FIG. 2B is a side view. In FIG. 2, the spring members 12'-3a, 12'-3b; 12'-4a, 12'-4b facing each other in FIG. 1 are omitted. That is, only two pairs of facing spring members 12'-1a, 12'-1b; 12'-2a, 12'-2b are provided.

図２のホールキャップは図３に示す係止ユニット３’に適用される。図３においては、係止ユニット３’は、円形の開口３１ａを有するカップ状部材３１と、開口３１ａを横切る２つの梁要素３２−１、３２−２の−（マイナス）状の梁部材３２’とによって構成される。 The hole cap of FIG. 2 is applied to the locking unit 3 'shown in FIG. In FIG. 3, the locking unit 3 ′ includes a cup-shaped member 31 having a circular opening 31 a and a − (minus) -shaped beam member 32 ′ of two beam elements 32-1 and 32-2 crossing the opening 31 a. It is comprised by.

尚、上述の実施の形態においては、梁部材を２つ又は４つの梁要素で構成したが、他の数の梁要素で構成できる。この場合には、対面したばね部材をその数の対だけ設ける。但し、対面したばね部材は複数対設けているが、少なくとも１対設ければよい。 In the above-described embodiment, the beam member is composed of two or four beam elements, but can be composed of other numbers of beam elements. In this case, the number of the facing spring members is provided. However, a plurality of facing spring members are provided, but at least one pair may be provided.

また、上述の実施の形態においては、係止ユニットの開口を円形としたが、他の形状たとえば矩形でもよい。この場合には、平坦円板は他の形状に合わせた平坦部材で構成する。 Moreover, in the above-mentioned embodiment, although the opening of the locking unit is circular, other shapes such as a rectangle may be used. In this case, the flat disk is formed of a flat member having another shape.

さらに、上述の実施の形態において、取外し棒用穴１３−１、１３−２を設け、取外し棒によってホールキャップを取外すようにしているが、これに限定されない。たとえば、平坦円板１１の周囲の一部を薄くしてドライバをここに差込むことによってホールキャップを取外してもよい。 Further, in the above-described embodiment, the removal rod holes 13-1 and 13-2 are provided, and the hole cap is removed by the removal rod. However, the present invention is not limited to this. For example, the hole cap may be removed by thinning a part of the periphery of the flat disk 11 and inserting a driver here.

さらにまた、本考案は上述の実施の形態の自明の範囲のいかなる変更にも適用し得る。 Furthermore, the present invention can be applied to any change in the obvious scope of the above-described embodiment.

本考案に係るホールキャップは艦船のヘリポート（甲板）、ポール立てユニット以外にも、水上ヘリポート、地上ヘリポート、建築現場等における穴にも利用できる。 The hole cap according to the present invention can be used not only for a ship heliport (deck) and a pole stand unit but also for a hole in a water heliport, a ground heliport, a construction site, and the like.
