【0001】
【発明の属する技術分野】
本発明は、車両のフロアに設けたサービスホールなどの開口を覆うロック機構を備えたカバー装置に関する。
【0002】
【従来の技術】
宅配便などに使用する車両には、荷室のフロアの下側に設けたバッテリなどのサービスのためのサービスホール(開口)を設け、これをロック機構を備えたカバー装置により覆ったものがある。これは例えば図4〜図6に示すように、フロア10に設けられたサービスホール11を、一側がフック18により係止される板金製のカバー15により覆い、カバー15のフック18と反対側となる部分をロック機構20Aによりフロア10に離脱可能に係止したものである。このロック機構20Aは、カバー15にはフック18と反対側に設けた挿通穴16に通したつまみ21のボス部21aの下端に掛止部材22をねじ止め固定し、フロア10に補強材12を介して固定したブラケット23の掛止部材22と対応する位置にはロック穴24を形成したものである。掛止部材22はその回転軸線と直交する直径方向に整列して1対の半径方向突出部22aを形成した板金部材であり、ロック穴24には各突出部22aと対応する1対の切欠き24aが形成されている。
【0003】
このロック機構20Aは、つまみ21により突出部22aの位置を切欠き24aの位置に合わせた状態では、掛止部材22がロック穴24内に挿入離脱自在であって、カバー15は図5の実線で示す位置と二点鎖線15Aに示す位置の間で、フック18による係止位置付近を中心として多少角度揺動可能である。掛止部材22がロック穴24内に挿入され、実線で示すようにカバー15がフロア10に当接してサービスホール11を覆った状態で、つまみ21により掛止部材22を回転すれば、突出部22aは切欠き24aから外れたロック穴24の縁部の裏側に係合され、掛止部材22がロック穴24から離脱しなくなるのでカバー15はロックされる。
【0004】
【発明が解決しようとする課題】
しかしながら上述した従来技術では、カバー15をサービスホール11に近づけた状態では掛止部材22およびロック穴24はカバー15の裏側に隠れて見えないので、図6の二点鎖線22Aに示すように突出部22aと切欠き24aの位置が合っていない状態でカバー15を閉じることがあり、その場合は図7に示すように、掛止部材22の突出部22aがロック穴24の周辺となるブラケット23の上面に当たり、ロック機構20Aを設けた側となるカバー15はフロア10の表面から多少浮き上がる。荷室内での作業者がこれに気づかずにカバー15を踏んだり重量物を置いたりすると、掛止部材22の突出部22aまたはカバー15が変形したり破損したりしてロック機構20が機能を果たさなくなるという問題がある。本発明はこのような問題を解決することを目的とする。
【0005】
【課題を解決するための手段】
このために、本発明によるロック機構を備えたカバー装置は、開口が設けられたフロアに一側が係止されこの一側とは反対側となる他側が開放可能となるように取り付けられて開口を覆うカバーと、このカバーの他側をフロアに離脱可能に係止するロック機構を備え、このロック機構は、カバーの他側の裏側に同カバーと直交する軸線回りに回転可能に支持されて半径方向の突出部が形成された掛止部材と、フロアに固定されて掛止部材と対応する位置に突出部が通過可能な切欠きを有するロック穴が形成されたブラケットよりなるものとし、突出部の位置を切欠きの位置に合わせた状態では掛止部材はロック穴内に挿入離脱自在であり、掛止部材がロック穴内に挿入されカバーがフロアに当接して開口を覆った状態で掛止部材を回転すれば突出部が切欠きから外れたロック穴の縁部に係合して掛止部材がロック穴から離脱しなくなるよう構成したロック機構を備えたカバー装置において、掛止部材には突出部の裏側からカバーと反対方向に突出するガイドを設けたことを特徴とするものである。
【0006】
前項に記載のロック機構を備えたカバー装置は、掛止部材の半径方向突出部は1対として掛止部材の回転軸線と直交する直径方向に整列して形成し、ロック穴の切欠きは各突出部に対応する1対とすることが好ましい。
【0007】
前2項に記載のロック機構を備えたカバー装置は、ガイドの先端のブラケットと当接する部分には円弧状の面取りを施すことが好ましい。
【0008】
【発明の作用および効果】
上述のように、本発明によれば、ロック機構の掛止部材には突出部の裏側からカバーと反対方向に突出するガイドを設けたので、突出部と切欠きの位置が合っていない状態でカバーを閉じようとすると、掛止部材の突出部に設けたガイドの先端がロック穴の周辺となるブラケットの上面に当たって、カバーのロック機構を設けた側はフロアの表面から大きく浮き上がる。このようにカバーはフロアから大きく浮き上がるので作業者は直ちにこれに気づき、突出部が切欠き内に入るように掛止部材を回転して、カバーがフロアに当接するようにすることができる。従ってフロアの表面から浮き上がったカバーを踏んだり重量物を置いたりして、掛止部材の突出部やカバーを変形させたり破損させたりするおそれはなくなる。
【0009】
掛止部材の半径方向の突出部は1対として掛止部材の回転軸線と直交する直径方向に整列して形成し、ロック穴の切欠きは各突出部に対応する1対とするようにしたロック機構を備えたカバー装置によれば、突出部と切欠きの位置が合っていない状態から合った状態にするために掛止部材を回転する際の、掛止部材の回転角およびカバーのロック機構側の上下動が少なくなるので、突出部と切欠きをの位置を合わせるための掛止部材の回転が容易になる。
【0010】
ガイドの先端のブラケットと当接する部分には円弧状の面取りを施したロック機構を備えたカバー装置によれば、突出部と切欠きの位置が合っていない状態から合った状態にするために掛止部材を回転する際のガイドの先端とブラケットとの間の摺動が円滑に行われるので、突出部と切欠きをの位置を合わせるための回転が円滑になる。
【0011】
【発明の実施の形態】
以下に、図1〜図3に示す実施の形態により、本発明によるロック機構を備えたカバー装置の説明をする。この実施の形態は、先に説明した従来技術に本発明を適用したものであり、本発明の要部であるガイドを除く構造は先に説明した従来技術のものと同一であるので、ガイドおよび先に説明を省略した部分につき主として説明する。
【0012】
図1は、図3の二点鎖線22Aに示すように、掛止部材22の突出部22aの位置がロック穴24の切欠き24aの位置と合っていない状態でフロア10にカバー15を取り付け、ガイド25の先端がロック穴24の周辺となるブラケット23の上面に当接してカバー15のロック機構20側が大きく浮き上がった状態の断面図であり、図2はカバー15がフロア10の表面に当接されてロック機構20によりロックされた状態の断面図である。図1および図2に示すように、サービスホール11の一側となるフロア10にねじ止め固定された浅いZ形断面形状のフック18とフロア10の表面との間には板金製のカバー15の一側が差し込まれて、カバー15はこの係止部付近を中心として多少角度揺動可能に係止され、カバー15のフック18と反対側となる部分はロック機構20により離脱可能にフロア10に係止されるようになっている。
【0013】
ロック機構20は、フロア10側に取り付けられるブラケット23と、カバー15側に取り付けられるつまみ21、掛止部材22およびガイド25よりなるものである。つまみ21は同軸的に形成されたボス部21aがカバー15の挿通穴16に回転可能に差し込まれ、カバー15の下側に突出するボス部21aの先端には掛止部材22の中心部がねじ止め固定されている。掛止部材22は、ボス部21aに固定される中心部に、つまみ21の回転軸線と直交する直径方向に互いに反対向きに整列された1対の半径方向突出部22aが形成された板金部材である。各突出部22aの先端部の裏側には、突出部22aの幅よりやや小径の丸棒をコ字状に折曲したガイド25の両先端が溶接などにより、突出部22aからカバー15と反対方向に突出するように固定されている。ガイド25の折曲部の外側の曲率半径は、その丸棒の直径よりも相当大きい値となる。
【0014】
ブラケット23は帯板をハット状に折曲した板金部品で、ロック機構20の下側となるサービスホール11内の一側を通る補強材12に溶接などにより取り付けられている。上面がフロア10の表面とほゞ一致するブラケット23の頂部には、サービスホール11を覆うように係止されたカバー15に設けた掛止部材22と対応する位置にロック穴24が形成されている。図3に示すように、ロック穴24は掛止部材22の中央部より大径の丸穴に、掛止部材22の突出部22aおよびガイド25が通過可能な1対の切欠き24aを直径方向に対向して形成したものである。
【0015】
図3に示すように、掛止部材22(およびガイド25)は、つまみ21をつかんで回すことにより、突出部22aがロック穴24と合う開閉位置(実線位置参照)と切欠き24aから外れたロック穴24の縁部に係合するロック位置(例えば二点鎖線22A参照)の間で回転可能である(矢印R参照)。なお図示は省略したが、掛止部材22とカバー15の間には、回転をこの開閉位置とロック位置の間に制限するストッパを設けるのがよい。
【0016】
つまみ21により掛止部材22を開閉位置とした状態で、カバー15の一側をフック18とフロア10の間に差し込み係止してカバー15を閉じれば、中央部を除く掛止部材22およびガイド25はロック穴24から下側に通り抜けて、カバー15はフロア10の表面に当接される。そしてこの状態でつまみ21により掛止部材22およびガイド25を時計回転方向に回転してロック位置とすれば、突出部22aが切欠き24aから外れたロック穴24の下縁部に係合して掛止部材22がロック穴24から離脱しなくなり、カバー15はロックされる(図2参照)。このロック位置からつまみ21により掛止部材22およびガイド25を反時計回転方向に回転して開閉位置とすれば、カバー15を開きフック18とフロア10の間から引き抜いてサービスホール11は開放することができる。
【0017】
掛止部材22がロック位置または開閉位置から外れた状態で、カバー15の一側をフック18の下側に差し込んでカバー15を閉じようとすれば、図1に示すように、各突出部22aの先端部の裏側からカバー15と反対方向に突出するように設けられたガイド25の先端の折曲部付近がロック穴24の周辺となるブラケット23の上面に当たるので、ロック機構20を設けた側となるカバー15はフロア10の表面から大きく浮き上がる。このようにカバー15はフロア10から大きく浮き上がるので作業者は直ちにこの異常に気づき、突出部22aが切欠き24a内に入るように掛止部材22をつまみ21により回して、カバー15がフロア10に当接するようにしてロックすることができる。従ってフロア10の表面から浮き上がったカバー15を踏んだり重量物を置いたりして、掛止部材22の突出部22aやカバー15を変形させたり破損させたりするおそれはなくなる。
【0018】
そして作業者は、つまみ21により掛止部材22およびガイド25を回転して開閉位置とし、ロック穴24内に入るようにしてカバー15をフロア10の表面に当接するように閉じ、再び掛止部材22およびガイド25を回転してカバー15をロックしてから、荷室内の作業を行えばよい。この掛止部材22およびガイド25を開閉位置とするための回転の際には、ガイド25の先端はブラケット23の上面に対し摺動される。ガイド25は切欠き24aと完全に合致する直前に切欠き24a内に落ち込み、次いで突出部22aも切欠き24a内に入るので、掛止部材22およびガイド25を開閉位置にするための操作は、きわめて容易である。
【0019】
上述した実施の形態では、掛止部材22の半径方向の突出部22aは1対として掛止部材22の回転軸線と直交する直径方向に整列して形成し、ロック穴24の切欠き24aも各突出部22aに対応して1対を形成するようにしており、このようにすれば図1と図3の二点鎖線22Aに示すように突出部22a(およびガイド25)と切欠き24aの位置が合っていない状態から合った状態にするために掛止部材22を回転する際の、掛止部材22の回転角およびカバー15のロック機構20側の上下動は、掛止部材22の突出部22aを片側に1個だけ設けた場合に比して半分程度になるので、このような修正のための掛止部材22の回転が容易になる。しかしながら本発明はこれに限られるものではなく、掛止部材22の突出部22aを1個として実施することもできる。この場合のガイド25は、先端部を半球状にした丸棒とすればよい。
【0020】
また上述した実施の形態では、ガイド25をコ字状に折曲した丸棒としてその両端を各突出部22aの裏側に固着しており、このようにすればガイド25の先端のブラケット23と当接する部分の曲率半径が大きくなり、この当接部分の摺動が円滑になるので、掛止部材22を図1に示すような開閉位置にない状態から、開閉位置にする際の回転が円滑に行われ、しかもガイド25は丸棒を曲げるだけであるので製造も容易である。しかしながら本発明はこれに限られるものではなく、ガイド25を板金部材としその先端のブラケット23と当接する部分に円弧状の面取りを施したものとして実施することも可能である。
【0021】
なお上記実施の形態では、カバー15は、フック18とフロア10の間に一側を差し込んでフロア10に係止して、この係止部付近を中心として多少角度揺動可能としているが、カバー15の一側はヒンジを用いて揺動自在にフロア10に取り付けてもよい。またカバー15の一側も、このようにフック18またはヒンジによりフロア10に取り付ける代わりに、ロック機構20によりフロア10に着脱可能に係止するようにしてもよい。

BACKGROUND OF THE INVENTION
The present invention relates to a cover device including a lock mechanism that covers an opening such as a service hole provided on a floor of a vehicle.
[0002]
[Prior art]
Some vehicles used for courier services have a service hole (opening) for services such as a battery provided below the floor of the luggage compartment, and this is covered with a cover device having a lock mechanism. . For example, as shown in FIGS. 4 to 6, the service hole 11 provided on the floor 10 is covered with a sheet metal cover 15 that is locked on one side by a hook 18, and the cover 15 has a side opposite to the hook 18. This portion is removably locked to the floor 10 by the lock mechanism 20A. The locking mechanism 20A is configured such that a hooking member 22 is screwed and fixed to a lower end of a boss portion 21a of a knob 21 that is passed through an insertion hole 16 provided on the opposite side of the hook 18 in the cover 15 and the reinforcing member 12 is attached to the floor 10. A lock hole 24 is formed at a position corresponding to the latch member 22 of the bracket 23 fixed via the lock hole 24. The latching member 22 is a sheet metal member that is aligned in the diametrical direction perpendicular to the rotation axis thereof to form a pair of radial protrusions 22a. The lock hole 24 has a pair of notches corresponding to the protrusions 22a. 24a is formed.
[0003]
In the lock mechanism 20A, in the state where the position of the protruding portion 22a is adjusted to the position of the notch 24a by the knob 21, the latch member 22 can be freely inserted into and removed from the lock hole 24, and the cover 15 is shown by the solid line in FIG. Between the position indicated by 2 and the position indicated by the two-dot chain line 15 </ b> A can be slightly swung around the vicinity of the locking position by the hook 18. If the latching member 22 is inserted into the lock hole 24 and the latching member 22 is rotated by the knob 21 in a state where the cover 15 is in contact with the floor 10 and covers the service hole 11 as shown by a solid line, the projecting portion 22a is engaged with the back side of the edge of the lock hole 24 that is disengaged from the notch 24a, and the cover member 15 is not detached from the lock hole 24, so that the cover 15 is locked.
[0004]
[Problems to be solved by the invention]
However, in the above-described prior art, the hooking member 22 and the lock hole 24 are hidden behind the cover 15 and cannot be seen when the cover 15 is close to the service hole 11, so that it protrudes as shown by a two-dot chain line 22 </ b> A in FIG. 6. The cover 15 may be closed in a state where the positions of the portion 22a and the notch 24a are not aligned. In this case, the bracket 23 in which the protruding portion 22a of the latching member 22 is the periphery of the lock hole 24 as shown in FIG. The cover 15 on the side where the lock mechanism 20 </ b> A is provided is slightly lifted from the surface of the floor 10. If an operator in the cargo compartment steps on the cover 15 or places a heavy object without noticing this, the projection 22a of the latch member 22 or the cover 15 is deformed or damaged, and the lock mechanism 20 functions. There is a problem that it will not be fulfilled. The present invention aims to solve such problems.
[0005]
[Means for Solving the Problems]
For this purpose, the cover device provided with the lock mechanism according to the present invention is attached so that one side is locked to the floor provided with the opening and the other side opposite to the one side can be opened. A cover mechanism and a lock mechanism for releasably locking the other side of the cover to the floor are provided. The lock mechanism is supported on the back side of the other side of the cover so as to be rotatable about an axis perpendicular to the cover and having a radius. And a bracket formed with a locking hole having a notch that is fixed to the floor and that allows the projection to pass through at a position corresponding to the latch member. The latch member can be freely inserted into and removed from the lock hole with the position of the notch aligned with the position of the notch, and the latch member is inserted into the lock hole and the cover is in contact with the floor and covers the opening. Rotate In the cover device having a lock mechanism configured such that the protruding portion engages with the edge of the lock hole that is removed from the notch so that the latch member is not detached from the lock hole. A guide projecting in the direction opposite to the cover is provided.
[0006]
In the cover device having the lock mechanism described in the previous section, the protrusions in the radial direction of the latching member are formed as a pair and aligned in the diametrical direction perpendicular to the rotation axis of the latching member. A pair corresponding to the protrusions is preferable.
[0007]
In the cover device having the lock mechanism described in the preceding two paragraphs, it is preferable that an arc-shaped chamfer is applied to a portion that contacts the bracket at the tip of the guide.
[0008]
Operation and effect of the invention
As described above, according to the present invention, the latch member of the lock mechanism is provided with the guide that projects in the direction opposite to the cover from the back side of the projecting portion, so that the position of the projecting portion and the notch is not aligned. When the cover is to be closed, the tip of the guide provided on the protruding portion of the latching member comes into contact with the upper surface of the bracket which is the periphery of the lock hole, and the side on which the cover is provided with the locking mechanism is greatly raised from the surface of the floor. In this way, the cover is greatly lifted off the floor, so that the operator immediately notices this, and the cover can be brought into contact with the floor by rotating the latch member so that the protruding portion enters the notch. Therefore, there is no possibility of stepping on the cover lifted from the surface of the floor or placing a heavy object to deform or damage the protrusion of the latch member or the cover.
[0009]
The protrusions in the radial direction of the latching member are formed as a pair aligned in the diametrical direction perpendicular to the rotation axis of the latching member, and the notch of the lock hole is a pair corresponding to each protrusion. According to the cover device provided with the lock mechanism, the rotation angle of the latching member and the lock of the cover when the latching member is rotated so that the position of the protrusion and the notch is matched with each other. Since the vertical movement on the mechanism side is reduced, it is easy to rotate the latch member for aligning the positions of the protrusion and the notch.
[0010]
According to the cover device having a lock mechanism with an arc chamfered chamfer on the portion of the guide that comes into contact with the bracket, it is necessary to hang the projection and the notch so that they are not aligned. Since the sliding between the tip of the guide and the bracket is smoothly performed when the stop member is rotated, the rotation for aligning the positions of the protrusion and the notch is smooth.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the cover device provided with the lock mechanism according to the present invention will be described with reference to the embodiment shown in FIGS. In this embodiment, the present invention is applied to the prior art described above, and the structure excluding the guide which is the main part of the present invention is the same as that of the prior art described above. The description of the parts that have been omitted will be mainly described.
[0012]
As shown in FIG. 3, the cover 15 is attached to the floor 10 in a state where the position of the protrusion 22 a of the latching member 22 does not match the position of the notch 24 a of the lock hole 24, as indicated by a two-dot chain line 22 </ b> A in FIG. 3. FIG. 2 is a cross-sectional view showing a state where the front end of the guide 25 is in contact with the upper surface of the bracket 23 around the lock hole 24 and the lock mechanism 20 side of the cover 15 is greatly lifted. FIG. FIG. 4 is a cross-sectional view showing a state where the lock mechanism 20 is locked. As shown in FIGS. 1 and 2, a sheet metal cover 15 is interposed between a shallow Z-shaped hook 18 screwed to the floor 10 on one side of the service hole 11 and the surface of the floor 10. One side is inserted, and the cover 15 is locked so as to be able to swing at a certain angle around the vicinity of the locking portion, and the portion of the cover 15 opposite to the hook 18 is engaged with the floor 10 so that it can be detached by the lock mechanism 20. It has come to be stopped.
[0013]
The lock mechanism 20 includes a bracket 23 attached to the floor 10 side, a knob 21 attached to the cover 15 side, a latch member 22, and a guide 25. The knob 21 has a coaxially formed boss portion 21 a rotatably inserted into the insertion hole 16 of the cover 15, and the center portion of the latching member 22 is screwed to the tip of the boss portion 21 a that protrudes below the cover 15. Stopped and fixed. The latching member 22 is a sheet metal member in which a pair of radial protrusions 22a aligned in opposite directions in the diameter direction perpendicular to the rotation axis of the knob 21 are formed at the center fixed to the boss 21a. is there. On the back side of the tip of each protrusion 22a, both ends of a guide 25, which is a round bar having a diameter slightly smaller than the width of the protrusion 22a, is welded to the opposite direction of the cover 15 from the protrusion 22a. It is fixed to protrude. The radius of curvature outside the bent portion of the guide 25 is a value considerably larger than the diameter of the round bar.
[0014]
The bracket 23 is a sheet metal part obtained by bending a band plate into a hat shape, and is attached to the reinforcing member 12 passing through one side in the service hole 11 below the lock mechanism 20 by welding or the like. A lock hole 24 is formed at a position corresponding to the latch member 22 provided on the cover 15 that is locked so as to cover the service hole 11 at the top of the bracket 23 whose upper surface substantially coincides with the surface of the floor 10. Yes. As shown in FIG. 3, the lock hole 24 is formed in a round hole having a larger diameter than the central portion of the latch member 22, and a pair of notches 24 a through which the protrusion 22 a and the guide 25 of the latch member 22 can pass are diametrically aligned. It is formed opposite to.
[0015]
As shown in FIG. 3, the latching member 22 (and the guide 25) is removed from the notch 24a and the opening / closing position (see the solid line position) where the protrusion 22a fits the lock hole 24 by grasping and turning the knob 21. It can rotate between lock positions (see, for example, two-dot chain line 22A) that engages with the edge of the lock hole 24 (see arrow R). Although not shown, it is preferable to provide a stopper between the latch member 22 and the cover 15 to limit the rotation between the open / close position and the lock position.
[0016]
If one side of the cover 15 is inserted and locked between the hook 18 and the floor 10 and the cover 15 is closed while the latch member 22 is in the open / closed position by the knob 21, the latch member 22 and the guide except for the central portion are closed. 25 passes through the lock hole 24 downward, and the cover 15 is brought into contact with the surface of the floor 10. In this state, if the latch member 22 and the guide 25 are rotated clockwise by the knob 21 to the lock position, the protrusion 22a is engaged with the lower edge of the lock hole 24 that is disengaged from the notch 24a. The latch member 22 does not detach from the lock hole 24, and the cover 15 is locked (see FIG. 2). If the latch member 22 and the guide 25 are rotated counterclockwise by the knob 21 from the locked position to the open / close position, the cover 15 is opened and the service hole 11 is opened by pulling it out from between the hook 18 and the floor 10. Can do.
[0017]
If one side of the cover 15 is inserted into the lower side of the hook 18 and the cover 15 is closed in a state where the latch member 22 is out of the locked position or the open / closed position, as shown in FIG. Since the vicinity of the bent portion at the front end of the guide 25 provided so as to protrude in the opposite direction to the cover 15 from the back side of the front end portion of the head contacts the upper surface of the bracket 23 around the lock hole 24, the side on which the lock mechanism 20 is provided. The cover 15 that is to be lifted greatly from the surface of the floor 10. Thus, since the cover 15 is greatly lifted from the floor 10, the operator immediately notices this abnormality, and the latch member 22 is turned by the knob 21 so that the protruding portion 22 a enters the notch 24 a, and the cover 15 is moved to the floor 10. It can be locked in contact. Therefore, there is no possibility that the cover 15 lifted from the surface of the floor 10 is stepped on or a heavy object is placed, and the protruding portion 22a of the latch member 22 and the cover 15 are deformed or damaged.
[0018]
Then, the operator rotates the latch member 22 and the guide 25 with the knob 21 to the open / close position, closes the cover 15 so as to enter the lock hole 24 and abuts the surface of the floor 10, and again the latch member. The work in the cargo compartment may be performed after the cover 15 is locked by rotating the 22 and the guide 25. During rotation for setting the latching member 22 and the guide 25 to the open / close position, the tip of the guide 25 is slid with respect to the upper surface of the bracket 23. Since the guide 25 falls into the notch 24a immediately before it completely matches the notch 24a, and the protrusion 22a also enters the notch 24a, the operation for setting the latching member 22 and the guide 25 to the open / close position is as follows. Very easy.
[0019]
In the embodiment described above, the protrusions 22a in the radial direction of the latching member 22 are formed as a pair and aligned in the diametrical direction perpendicular to the rotation axis of the latching member 22, and the notches 24a of the lock hole 24 are also formed in each of them. A pair is formed corresponding to the protrusion 22a, and in this way, the position of the protrusion 22a (and the guide 25) and the notch 24a as shown by a two-dot chain line 22A in FIGS. The rotation angle of the latching member 22 and the up-and-down movement of the cover 15 on the lock mechanism 20 side when the latching member 22 is rotated in order to change from the non-matching state to the matching state are the protrusions of the latching member 22. Since it becomes about half as compared with the case where only one 22a is provided on one side, it is easy to rotate the latch member 22 for such correction. However, the present invention is not limited to this, and the protrusion 22a of the latching member 22 can be implemented as one. The guide 25 in this case may be a round bar with a hemispherical tip.
[0020]
In the above-described embodiment, the guide 25 is a round bar bent in a U-shape, and both ends thereof are fixed to the back side of each protruding portion 22a. Since the radius of curvature of the contact portion is increased and the sliding of the contact portion is smooth, the rotation when the latch member 22 is not in the open / closed position as shown in FIG. Moreover, the guide 25 is easy to manufacture because it only bends the round bar. However, the present invention is not limited to this, and the guide 25 may be a sheet metal member, and may be implemented as an arc chamfered portion that is in contact with the bracket 23 at the tip.
[0021]
In the above embodiment, the cover 15 is inserted into one side between the hook 18 and the floor 10 and locked to the floor 10 so that the cover 15 can swing a little around the locking portion. One side of 15 may be swingably attached to the floor 10 using a hinge. In addition, one side of the cover 15 may be detachably locked to the floor 10 by the lock mechanism 20 instead of being attached to the floor 10 by the hook 18 or the hinge as described above.
