しかしながら、従来の蝶番金具を用いた蝶番装置は、部品点数が多く、かつ、扉及び枠体への組み付けが面倒であるという課題がある。   However, the hinge device using the conventional hinge metal has a problem that the number of parts is large and the assembly to the door and the frame is troublesome.

上記の点に鑑み、本発明は、蝶番金具のような蝶番装置を使用することなく、扉を開いた状態で保持させる機能を有する収納箱を実現することを目的とする。   In view of the above points, an object of the present invention is to realize a storage box having a function of holding a door in an open state without using a hinge device such as a hinge fitting.

本発明に係る収納箱は、箱本体に対して、可動連結部によって閉位置と開位置との間を揺動可能に軸支された扉を備えており、扉が開位置にあるときに係合凸部と係合爪部とが係合して扉が起立状態に保持される一方、扉が閉位置にあるときに係合凸部と係合爪部との係合は解除されており、かつ、扉が開位置と閉位置との間を移動するときに係合凸部が係合爪部を変形させる(撓ませる)ようにした。   The storage box according to the present invention includes a door that is pivotally supported by a movable coupling portion with respect to the box body so as to be swingable between a closed position and an open position, and is engaged when the door is in the open position. While the joint convex part and the engaging claw part are engaged and the door is held in an upright state, the engagement between the engaging convex part and the engaging claw part is released when the door is in the closed position. In addition, when the door moves between the open position and the closed position, the engagement convex portion deforms (bends) the engagement claw portion.

すなわち、本発明の一態様では、操作部を有する電気機器を収納する収納箱であって、前記電気機器が取り付けられ、前記電気機器の操作部が露出される開口を有する箱本体と、前記開口を覆う扉と、前記箱本体及び前記扉の一方に一体的に設けられる軸部と、他方に一体的に設けられ、該軸部を揺動可能に支持する軸受部とを有する可動連結部と、前記箱本体及び前記扉の一方に一体的に設けられる係合凸部と、前記箱本体及び前記扉の他方に一体的に設けられ、前記係合凸部との係合により前記軸部の軸方向に弾性変形が可能な係合爪部とを備え、前記扉は、前記可動連結部によって前記開口を覆う閉位置と前記箱本体から起立する開位置との間を揺動可能に軸支されており、前記扉が前記開位置にあるときに前記係合凸部と前記係合爪部とが係合して該扉が前記開位置(起立状態)に保持される一方、前記扉が前記閉位置にあるときに前記係合凸部と前記係合爪部との係合は解除されており、かつ、前記扉が前記開位置と前記閉位置との間を移動するときに前記係合凸部が前記係合爪部を前記軸方向に押して変形させる(例えば、撓ませる)ように構成されている。 That is, in one aspect of the present invention, a storage box that stores an electric device having an operation unit, the box body having an opening to which the electric device is attached and the operation unit of the electric device is exposed, and the opening A movable connecting portion having a door that covers the shaft, a shaft portion that is integrally provided on one of the box body and the door, and a bearing portion that is integrally provided on the other and supports the shaft portion so as to be swingable. An engagement protrusion provided integrally on one of the box body and the door; and an engagement protrusion provided integrally on the other of the box body and the door ; An engaging claw that is elastically deformable in the axial direction, and the door is pivotally supported so as to be swingable between a closed position that covers the opening by the movable connecting portion and an open position that stands up from the box body. The engaging projection and the engaging claw when the door is in the open position. Are engaged and the door is held in the open position (standing state), while the engagement convex portion and the engagement claw portion are disengaged when the door is in the closed position. And, when the door moves between the open position and the closed position, the engagement convex portion pushes the engagement claw portion in the axial direction to deform (for example, bend). It is configured.

この態様によると、扉は、箱本体/扉に一体的に設けられた可動連結部(軸部/軸受部)によって、閉位置と開位置との間を揺動可能に軸支されている。さらに、扉は、箱本体/扉に一体的に設けられた係合凸部と係合爪部との係合によって、箱本体に対して開位置(起立状態)に保持することが可能に構成されている。すなわち、本態様の収納箱は、蝶番金具のような蝶番装置を使用することなく、箱本体/扉に一体的に設けられた係合凸部/係合爪部の作用(係合)により、扉を開いた状態で保持させる機能を有している。これにより、従来の蝶番装置が有していた機能を本体ケース及び扉によって実現することができ、部品点数を削減することができる。   According to this aspect, the door is pivotally supported so as to be swingable between the closed position and the open position by the movable connecting portion (shaft portion / bearing portion) provided integrally with the box body / door. Furthermore, the door is configured to be able to be held in an open position (standing state) with respect to the box body by the engagement of the engaging protrusions and the engaging claws provided integrally with the box body / door. Has been. That is, the storage box according to the present aspect can be obtained by the action (engagement) of the engagement convex portion / engagement claw portion integrally provided on the box body / door without using a hinge device such as a hinge metal fitting. It has the function of holding the door open. Thereby, the function which the conventional hinge apparatus had can be implement | achieved with a main body case and a door, and a number of parts can be reduced.

さらに、可動連結部(軸部/軸受部)と、係合凸部/係合爪部とがそれぞれ独立して設けられているため、可動連結部による扉の揺動動作と、係合凸部/係合爪部による係合及びその解除動作とが互いに干渉しないようにすることができる。例えば、扉の開位置から閉位置への移動に際して、係合凸部が係合爪部を変形させて(例えば、撓ませて)その係合を解除するときに、この係合解除動作が扉の揺動動作を干渉しないようにすることができる。これにより、扉の揺動時におけるがたつきや可動連結部の軸部が軸受部から外れること等を防止することができるとともに、扉のスムーズな揺動動作を確保することができる。   Further, since the movable connecting part (shaft part / bearing part) and the engaging convex part / engaging claw part are provided independently, the swinging movement of the door by the movable connecting part and the engaging convex part / The engagement by the engaging claw portion and the releasing operation thereof can be prevented from interfering with each other. For example, when the door is moved from the open position to the closed position, when the engagement convex portion deforms (for example, bends) the engagement claw portion to release the engagement, the engagement release operation is performed. It is possible to prevent interference with the swinging motion. As a result, it is possible to prevent rattling during the swinging of the door, the shaft portion of the movable connecting portion from being detached from the bearing portion, and the like, and to ensure a smooth swinging operation of the door.

また、上の態様の収納箱において、複数の前記可動連結部が前記軸部の軸方向(以下、単に軸方向ともいう)に離間するように設けられており、前記複数の可動連結部は、前記係合凸部及び前記係合爪部よりも前記軸方向の両外側に配置されている、ように構成されていてもよい。   Further, in the storage box of the above aspect, the plurality of movable connecting portions are provided so as to be separated in the axial direction of the shaft portion (hereinafter also simply referred to as the axial direction), and the plurality of movable connecting portions are: You may be comprised so that it may arrange | position on the both outer sides of the said axial direction rather than the said engagement convex part and the said engagement nail | claw part.

この構成によると、係合凸部と係合爪部とによる係合動作及びその解除動作は、可動連結部の軸方向内側で行われるため、可動連結部の軸部と軸受部との連結部分のぶれによる影響を低減させることが可能になる。これにより、上記の係合動作(解除動作)が可動連結部の軸方向外側で行われる場合と比較して、係合凸部と係合爪部とが安定的な位置であたるようにすることができる。すなわち、係合凸部と係合爪部との係合時のあたり位置(解除時のあたり位置)を安定化させることができる。さらに、可動連結部が、係合凸部及び係合爪部より軸方向外側に設けられていることにより、扉の揺動時において回転軸に対して力が伝わりやすく、可動連結部(扉)のがたつきやぶれが生じにくくなる。   According to this configuration, since the engaging operation and the releasing operation by the engaging convex portion and the engaging claw portion are performed on the inner side in the axial direction of the movable connecting portion, the connecting portion between the shaft portion of the movable connecting portion and the bearing portion. It is possible to reduce the influence of shaking. Thereby, compared with the case where said engagement operation | movement (release operation | movement) is performed in the axial direction outer side of a movable connection part, it is made for an engagement convex part and an engagement nail | claw part to be a stable position. Can do. That is, it is possible to stabilize the contact position at the time of engagement between the engagement convex portion and the engagement claw portion (the contact position at the time of release). Further, since the movable connecting portion is provided on the outer side in the axial direction from the engaging convex portion and the engaging claw portion, the force is easily transmitted to the rotating shaft when the door swings, and the movable connecting portion (door) Shaking and shaking are less likely to occur.

また、上の態様の収納箱において、前記係合凸部及び前記係合爪部は、それぞれ、前記箱本体又は前記扉から起立しており、前記扉が前記開位置にあるときに前記係合凸部と前記係合爪部との先端部同士が係合し、かつ、前記扉が前記開位置と前記閉位置との間を移動するときに前記係合凸部の先端部が前記係合爪部の先端部を前記軸部の軸方向に押して変形させる(例えば、撓ませる)、ように構成されていてもよい。   Further, in the storage box of the above aspect, each of the engagement convex portion and the engagement claw portion stands up from the box body or the door, and the engagement is performed when the door is in the open position. When the front ends of the convex portion and the engaging claw portion are engaged with each other and the door moves between the open position and the closed position, the front end portion of the engaging convex portion is engaged. You may comprise so that the front-end | tip part of a nail | claw part may be deform | transformed by pushing in the axial direction of the said axial part (for example, it bends).

この構成によると、扉の開閉動作において、係合凸部と係合爪部との先端部同士があたって、係合凸部と係合爪部との係合及びその解除が行われる。これにより、開位置において係合凸部と係合爪部とが係合した係合状態から係合爪部が変形させられた(例えば、撓ませられた)後、その係合が解除された係合解除状態までの間で係合爪部が変形している(例えば、撓んでいる)期間を短くすることができる。上記の係合爪部が変形している(例えば、撓んでいる)期間が長い場合(例えば、係合凸部の機能を本体カバーの壁面等で実現する場合)、係合爪部の弾性力を強めると扉のスムーズな開閉が阻害される場合がある。一方で、本態様の構成は、係合爪部が撓んでいる期間が短いため、係合爪部の弾性力を強めても扉のスムーズな開閉が阻害されない。これにより、長期間の使用においても、経年劣化や継続使用によって弾性力が弱まって扉の起立保持状態が保てなくなることを防ぐことができる。   According to this configuration, in the door opening / closing operation, the front ends of the engaging convex portion and the engaging claw portion hit each other, and the engaging convex portion and the engaging claw portion are engaged and released. As a result, the engagement claw portion is deformed (for example, deflected) from the engagement state in which the engagement convex portion and the engagement claw portion are engaged in the open position, and then the engagement is released. It is possible to shorten the period during which the engaging claw is deformed (for example, bent) until the engagement is released. When the engagement claw part is deformed (for example, bent) for a long time (for example, when the function of the engagement convex part is realized by the wall surface of the body cover), the elastic force of the engagement claw part If the strength is increased, smooth opening and closing of the door may be hindered. On the other hand, in the configuration of this aspect, since the period during which the engaging claw portion is bent is short, smooth opening and closing of the door is not inhibited even if the elastic force of the engaging claw portion is increased. Thereby, even if it is used for a long period of time, it can be prevented that the elastic force is weakened due to deterioration over time or continuous use and the door cannot be maintained in a standing state.

また、上の態様の収納箱において、前記扉は、該扉に設けられた前記軸部又は前記軸受部と、該扉に設けられた前記係合凸部又は前記係合爪部との間において、前記軸部の軸方向と直交する方向に切り欠かれている、ように構成されていてもよい。   Further, in the storage box of the above aspect, the door is between the shaft portion or the bearing portion provided on the door and the engagement convex portion or the engagement claw portion provided on the door. , And may be configured to be cut out in a direction orthogonal to the axial direction of the shaft portion.

この構成によると、可動連結部による扉の揺動動作と、係合凸部/係合爪部による係合及びその解除動作との間の干渉をより確実に防ぐことができる。   According to this configuration, it is possible to more reliably prevent interference between the swinging operation of the door by the movable connecting portion and the engagement and release operation by the engagement convex portion / engagement claw portion.

本発明によれば、扉を開閉位置間で揺動可能にする機能及び扉を開位置(起立状態)に保持する機能を、箱本体/扉に一体的に設けられた可動連結部、係合凸部及び係合爪部によって実現することができるため、従来技術と比較して部品点数を削減することができる。さらに、可動連結部と係合凸部/係合爪部とがそれぞれ独立して設けられているため、扉の揺動時におけるがたつきや可動連結部の軸部が軸受部から外れること等を防止することができるとともに、扉のスムーズな揺動動作を確保することができる。   According to the present invention, the function of enabling the door to swing between the open / closed positions and the function of holding the door in the open position (upright state) include a movable connecting portion integrally provided in the box body / door, and engagement. Since it can implement | achieve by a convex part and an engaging claw part, a number of parts can be reduced compared with a prior art. Further, since the movable connecting portion and the engaging convex portion / engaging claw portion are provided independently, rattling when the door swings, the shaft portion of the movable connecting portion is detached from the bearing portion, etc. Can be prevented and a smooth swinging motion of the door can be ensured.

さらに、係合凸部と係合爪部との先端部同士が係合したり、係合凸部の先端部が係合爪部の先端部を変形させたり(撓ませたり)するように構成することで、係合爪部が変形している(撓んでいる)期間を短くすることができるため、係合爪部の弾性力を強めても扉のスムーズな開閉が阻害されない。これにより、長期間の使用においても、経年劣化や継続使用によって弾性力が弱まって扉の起立保持状態が保てなくなること防ぐことができる。   Furthermore, the tip portions of the engaging convex portion and the engaging claw portion are engaged with each other, and the leading end portion of the engaging convex portion deforms (bends) the leading end portion of the engaging claw portion. By doing so, the period during which the engaging claw portion is deformed (deflected) can be shortened, so that the smooth opening and closing of the door is not hindered even if the elastic force of the engaging claw portion is increased. Thereby, even in long-term use, it is possible to prevent the elastic force from being weakened due to deterioration over time or continuous use, so that the standing upright state of the door cannot be maintained.

The engaging claws 32b are configured in a triangular shape such that the front end is narrow and gradually widens toward the rear side when viewed from the bottom (the state viewed from below, the same applies hereinafter). Further, a reinforcing plate 32c (see FIG. 4) extending forward from the bottom plate 30e is provided integrally with the base portion 32a on the outer side in the left-right direction of the base portion 32a. The reinforcing plate 32c has the widest width at the joint between the base portion 32a and the bottom plate 30e, and the width decreases as the distance from the base portion 32a increases on the end side (front side) of the base portion 32a and on the bottom plate 30e. As a result, compared to the case where the reinforcing plate 32c is not provided, the rigidity of the engaging claw portion 32 is increased in the left-right direction, and the engaging claw portion 32 is elastically deformed outward in the left-right direction (see arrow D1 in FIG. 4). In this case, the restoring force (elastic force) can be increased. With such a configuration, even during long-term use, the elastic force (restoring force when elastically deformed) is weakened due to aging and continuous use, and the door can be kept standing in the open position. It can be prevented from disappearing. Note that the shape of the engagement claw 32b as viewed from the bottom is not limited to a triangular shape. For example, the door 20 may be configured to be bent by an engagement end 22d of an engagement protrusion 22 described later when the door 20 is opened and closed. Good.

また、前板30aの上端部において、両凹部30c,30c間が凹部30cと連続するように、かつ側面視で円弧状に凹む凹部30fが形成されており、扉20が揺動する際に、上板20cが前板30aにあたらないようにしている。   Further, in the upper end portion of the front plate 30a, a recess 30f that is recessed in an arc shape in a side view is formed so that the space between both the recesses 30c and 30c is continuous with the recess 30c, and when the door 20 swings, The upper plate 20c is prevented from hitting the front plate 30a.

なお、本開示において端部とは、端だけに限らず、端と端寄りの部位とを包含する概念である。例えば、先端部とは、先端及び先端近傍にある先端寄りの部位の両方を包含する部分(部位)を指すものとし、上端部、前端部、両端部等においても同様とする。   In the present disclosure, the term “end” is a concept that includes not only an end but also an end and a portion near the end. For example, the tip portion refers to a portion (part) including both the tip and a portion near the tip near the tip, and the same applies to the upper end portion, the front end portion, both end portions, and the like.

扉20は、本体カバー30の前板30aの全体を覆うように構成されている。20aは、上下左右方向に延びる前板であり、20bは、前板20aの左右両側に一体的に設けられた側板であり、左右方向に向かって徐々に広がるように傾斜している。また、20c/20dは、前板20aの上側/下側に一体的に設けられた上板/下板であり、上方向/下方向に向かって徐々に広がるように傾斜している。なお、扉20は、開位置において、上板20cの一部が本体カバー30の上側の側板30bの一部にあたるように構成されており、開位置を超える揺動をしないようになっている。   The door 20 is configured to cover the entire front plate 30 a of the main body cover 30. 20a is a front plate extending in the vertical and horizontal directions, and 20b is a side plate integrally provided on both the left and right sides of the front plate 20a, and is inclined so as to gradually spread in the horizontal direction. 20c / 20d is an upper plate / lower plate provided integrally on the upper side / lower side of the front plate 20a, and is inclined so as to gradually spread upward / downward. The door 20 is configured such that a part of the upper plate 20c corresponds to a part of the side plate 30b on the upper side of the main body cover 30 in the open position, and does not swing beyond the open position.

軸受板21は、上板20cの左右方向両端部の内側において、凹部30cの側壁30dと略平行になるように上板20cから内方(下方)に向かって一体的に突設されている。軸受板21の先端部における上下方向の中間部分には、軸部31の軸方向(左右方向、以下単に軸方向ともいう)に貫通する貫通孔からなる軸受部21aが形成されている。軸受部21aの直径は、軸部31の直径よりも若干大きくなっている。可動連結部50は、この軸受部21aと、軸部31とによって構成されている。そして、軸受部21aが軸部31を揺動可能に支持することにより、扉20が閉位置と開位置との間を揺動できるようになっている。   The bearing plate 21 is integrally protruded inward (downward) from the upper plate 20c so as to be substantially parallel to the side wall 30d of the recess 30c inside the left and right ends of the upper plate 20c. A bearing portion 21a formed of a through-hole penetrating in the axial direction of the shaft portion 31 (left-right direction, hereinafter also simply referred to as the axial direction) is formed at an intermediate portion in the vertical direction at the front end portion of the bearing plate 21. The diameter of the bearing portion 21 a is slightly larger than the diameter of the shaft portion 31. The movable connecting portion 50 is constituted by the bearing portion 21 a and the shaft portion 31. The bearing portion 21a supports the shaft portion 31 so as to be swingable, so that the door 20 can swing between the closed position and the open position.

また、軸受板21には、扉20が閉位置にある状態で軸受板21の後端を円弧上に切り欠いた切欠部21cと、切欠部21cと軸受部21aとの間において軸部31を案内する案内溝21bとが形成されている。このような構成にすることにより、扉20を本体カバー30に取り付ける際には、扉20の前板20aと本体カバー30の前板30aとを対向させた状態で、上記切欠部21cを軸部31に対して前側から当接させた後、扉20を後側に押し込んで軸部31を案内溝21bで案内しながら軸受部21aに挿入させることにより、簡単に取り付けすることができる。   Further, the bearing plate 21 has a notch 21c in which the rear end of the bearing plate 21 is cut out on an arc in a state where the door 20 is in the closed position, and a shaft portion 31 between the notch 21c and the bearing 21a. A guide groove 21b for guiding is formed. With such a configuration, when the door 20 is attached to the main body cover 30, the notch portion 21 c is a shaft portion with the front plate 20 a of the door 20 and the front plate 30 a of the main body cover 30 facing each other. After making it contact | abut with respect to 31 from the front side, it can attach simply by pushing in the door 20 to the back side, and inserting the axial part 31 in the bearing part 21a, guiding with the guide groove 21b.

一方、扉20を一旦取り付けた後は、軸受部21aに軸部31が嵌まり込んでいるため、不用意に扉20が外れてしまうことがない。   On the other hand, once the door 20 is attached, the shaft portion 31 is fitted into the bearing portion 21a, so that the door 20 is not inadvertently detached.

なお、扉20が開いている状態では、図4(a)に示すように、案内溝21bは取り付ける時の状態から回転し下側に向かって延びた状態になり、軸部31の案内機能は解除される。このため、扉20の開動作に伴って、扉20に前後方向の力が加わっても扉20の耐外れ性が確保されるから扉20が本体カバー30から簡単に外れないようになっている。   In the state where the door 20 is open, as shown in FIG. 4 (a), the guide groove 21b is rotated from the mounting state and extends downward, and the guide function of the shaft portion 31 is as follows. Canceled. For this reason, with the opening operation of the door 20, even if a force in the front-rear direction is applied to the door 20, the door 20 is prevented from being easily detached from the main body cover 30 because the door 20 is secured against detachment. .

係合凸部22は、軸受板21の左右方向の内側において、軸受板21と略平行になるように上板20cから内方(扉20が開位置にあるときの下方)に向かって一体的に突設されている。係合凸部22は、断面H形状であり、軸受板21と略平行に延びる係合側板22aと、係合側板22aよりも内側(図4,5で左側)において係合側板22aと略平行に延びる係合側板22bと、係合側板22a,22bの前後方向の中間同士を連結する係合連結板22cとを備えている。係合側板22a,22bの先端は、係合連結板22cの下側において切り欠かれ、これにより係合凸部22の先端部には、係合端部22dが形成されている。この係合端部22dは、扉20が開位置と閉位置との間を移動するときに係合爪32bを軸方向外側(図4の矢印D1参照)に押して、係合爪部32を軸方向外側に撓ませるように構成されている。   The engaging convex portion 22 is integrated from the upper plate 20 c toward the inside (downward when the door 20 is in the open position) so as to be substantially parallel to the bearing plate 21 on the inner side in the left-right direction of the bearing plate 21. Projected to The engagement convex portion 22 has an H-shaped cross section, and is substantially parallel to the engagement side plate 22a on the inner side (left side in FIGS. 4 and 5) of the engagement side plate 22a extending substantially parallel to the bearing plate 21 and the engagement side plate 22a. And an engagement connecting plate 22c for connecting intermediate portions in the front-rear direction of the engagement side plates 22a and 22b. The front ends of the engagement side plates 22a and 22b are notched on the lower side of the engagement connecting plate 22c, whereby an engagement end portion 22d is formed at the front end portion of the engagement convex portion 22. The engagement end portion 22d pushes the engagement claw 32b outward in the axial direction (see arrow D1 in FIG. 4) when the door 20 moves between the open position and the closed position, so that the engagement claw portion 32 is pivoted. It is configured to bend outward in the direction.

図4(b)及び図5(b)に示すように、軸受板21と係合凸部22との間は、連結板24によって連結されている。これにより、軸受板21及び係合凸部22の軸方向(左右方向)への強度を高めることができる。また、収納箱を住宅等の壁面や屋内外に設置されたポール等に固定取付した場合に、収納箱の上方から塵埃や雨水が収納箱内部に侵入することを抑制することができる。   As shown in FIGS. 4B and 5B, the bearing plate 21 and the engaging convex portion 22 are connected by a connecting plate 24. Thereby, the intensity | strength to the axial direction (left-right direction) of the bearing board 21 and the engagement convex part 22 can be raised. In addition, when the storage box is fixedly attached to a wall surface of a house or a pole installed indoors or outdoors, it is possible to prevent dust and rainwater from entering the storage box from above the storage box.

一方で、連結板24の係合凸部22側の先端部(図4(b)の下側)には、上下方向に切り欠かれた切欠部24aが設けられている。このように、切欠部24aを設けることによって、仮に係合端部22dが係合爪32bを軸方向外側に押した際の反力で撓んだ場合においても、その影響により軸受部21aと軸部31との係合部分(連結部分)に影響がでないようにすることができる。なお、切欠部24aが設けられる位置及び形状は、図4(b)の位置及び形状に限定されない。例えば、切欠部24aが連結板24の軸受板21側の先端部に設けられていてもよい。また、切欠部24aの切欠の図4における上下方向深さが図4(b)よりも深くてもかまわない。   On the other hand, a cutout portion 24a cut out in the vertical direction is provided at the front end portion of the connecting plate 24 on the engagement convex portion 22 side (the lower side in FIG. 4B). Thus, by providing the notch 24a, even if the engagement end 22d is bent by a reaction force when the engagement claw 32b is pushed outward in the axial direction, the bearing 21a and the shaft are affected by the influence. It is possible to prevent the engagement portion (connection portion) with the portion 31 from being affected. In addition, the position and shape in which the notch part 24a is provided are not limited to the position and shape of FIG.4 (b). For example, the notch 24a may be provided at the tip of the connecting plate 24 on the bearing plate 21 side. Further, the depth in the vertical direction in FIG. 4 of the notch 24a may be deeper than that in FIG. 4B.

図1に戻り、扉20の閉位置における下端部には、係合部23が設けられており、本体カバー30の前板30aの下端部には、係合部23と対応する位置に被係合部35が設けられている。そして、扉20が閉位置に揺動された際に、上記係合部23と被係合部35とが係合することにより、扉20は閉位置に保持される。   Returning to FIG. 1, an engaging portion 23 is provided at the lower end portion of the door 20 in the closed position, and the lower end portion of the front plate 30 a of the main body cover 30 is engaged at a position corresponding to the engaging portion 23. A joint portion 35 is provided. When the door 20 is swung to the closed position, the engaging portion 23 and the engaged portion 35 are engaged, whereby the door 20 is held at the closed position.

(扉の開閉動作)
扉20の開閉動作について、図3〜図5を用いて詳細に説明する。
(Door open / close operation)
The opening / closing operation | movement of the door 20 is demonstrated in detail using FIGS.

まず、扉20が本体カバー30から起立した位置である開位置(以下、単に開位置ともいう)から、扉20が本体カバー30の開口部33を覆う閉位置(以下、単に開位置ともいう)に移動する際の閉動作について説明する。図3(a)及び図4に示すように、開位置では、係合凸部22の係合端部22dと係合爪部32の係合爪32bとが係合して扉20が起立状態(係合状態)に保持される。具体的には、係合爪32bの前端が係合端部22dの後端を支持して係合端部22dが後方(図3(a)の下方向)に移動しないように保持することにより、扉20が起立状態に保持される。   First, from the open position (hereinafter also simply referred to as the open position) where the door 20 stands from the main body cover 30, the door 20 covers the opening 33 of the main body cover 30 (hereinafter also simply referred to as the open position). The closing operation at the time of moving to will be described. As shown in FIGS. 3A and 4, in the open position, the engagement end 22 d of the engagement projection 22 and the engagement claw 32 b of the engagement claw 32 engage and the door 20 stands up. (Engaged state). Specifically, the front end of the engagement claw 32b supports the rear end of the engagement end 22d, and the engagement end 22d is held so as not to move backward (downward in FIG. 3A). The door 20 is held in an upright state.

ここで、扉20に閉位置に向かう方向の力が加えられると、上記係合端部22dにもそれに伴って後側方向の力が加えられる。この係合端部22dに加えられた力によって、係合爪32bが軸方向外側(図4の矢印D1方向側)に押されて、係合爪部32が軸方向外側に撓む。さらに継続して上記の力が加えられると、係合端部22dは、係合爪部32を軸方向外側に撓ませながら、後側に進み、係合端部22dの前端が係合爪32bの後端を通過すると、図3(a)の仮想線及び図5に示すように、係合爪部32は撓ませられる前の状態に戻り、係合端部22dと係合爪32bとの係合が解除された係合解除状態になる。その後、扉20が閉位置まで揺動されると、扉20の係合部23と本体カバー30の被係合部35とが係合することにより、扉20は閉位置に保持される(図3(b)参照)。   Here, when a force in a direction toward the closed position is applied to the door 20, a force in the rear direction is also applied to the engagement end portion 22d. Due to the force applied to the engaging end 22d, the engaging claw 32b is pushed outward in the axial direction (arrow D1 direction side in FIG. 4), and the engaging claw 32 is bent outward in the axial direction. When the above force is further applied, the engagement end 22d advances to the rear side while bending the engagement claw 32 outward in the axial direction, and the front end of the engagement end 22d is engaged with the engagement claw 32b. When passing the rear end, as shown in the phantom line of FIG. 3A and FIG. 5, the engagement claw portion 32 returns to the state before being bent, and the engagement end portion 22d and the engagement claw 32b The engaged state is released when the engagement is released. After that, when the door 20 is swung to the closed position, the engagement portion 23 of the door 20 and the engaged portion 35 of the main body cover 30 are engaged, whereby the door 20 is held in the closed position (see FIG. 3 (b)).

次に、扉20が閉位置から開位置に移動する際の開動作について説明する。閉位置にある扉20の下端部(図1(b)で“PUSH”と記載)を前側から押すことにより、扉20の係合部23と本体カバー30の被係合部35との係合が解除される。その後、扉20が閉位置から開位置に向かって揺動させられると、図3(a)の仮想線で示すように、係合端部22dの上端が係合爪32bの下端にあたる。扉20がさらに開位置に向かって揺動させられると、係合爪32bが軸方向外側(図5の矢印D2方向側)に押されて、係合爪部32が軸方向外側に撓む。その後、係合端部22dは、係合爪部32を軸方向外側に撓ませながら、前側に進み、係合端部22dの後端が係合爪32bの前端を通過すると、図3(a)実線及び図4に示すように、係合爪32bの前端が係合端部22dの後端を支持する係合状態になり、扉20が起立状態に保持される。   Next, the opening operation when the door 20 moves from the closed position to the open position will be described. Engagement between the engaging portion 23 of the door 20 and the engaged portion 35 of the main body cover 30 by pushing the lower end portion of the door 20 in the closed position (described as “PUSH” in FIG. 1B) from the front side. Is released. Thereafter, when the door 20 is swung from the closed position toward the open position, the upper end of the engagement end portion 22d corresponds to the lower end of the engagement claw 32b as indicated by the phantom line in FIG. When the door 20 is further swung toward the open position, the engaging claw 32b is pushed outward in the axial direction (arrow D2 direction side in FIG. 5), and the engaging claw 32 is bent outward in the axial direction. Thereafter, the engagement end portion 22d advances forward while bending the engagement claw portion 32 outward in the axial direction, and when the rear end of the engagement end portion 22d passes the front end of the engagement claw 32b, FIG. 4) As shown in the solid line and FIG. 4, the front end of the engagement claw 32b is in an engagement state that supports the rear end of the engagement end portion 22d, and the door 20 is held upright.

以上のように、本実施形態によると、扉20は、可動連結部50によって閉位置と開位置との間を揺動可能に軸支されるとともに、係合凸部22と係合爪部32との係合によって開位置で起立状態に保持されるように構成されている。これにより、本実施形態の収納箱10は、蝶番金具のような蝶番装置を使用することなく、扉20の開閉機能及び扉20を開いた状態で保持させる保持機能を実現しており、従来技術と比較して部品点数を削減することができる。   As described above, according to the present embodiment, the door 20 is pivotally supported by the movable connecting portion 50 so as to be swingable between the closed position and the open position, and the engaging convex portion 22 and the engaging claw portion 32 are supported. It is comprised so that it may be hold | maintained at an open position by engagement. Thereby, the storage box 10 of this embodiment has realized the opening / closing function of the door 20 and the holding function of holding the door 20 in an open state without using a hinge device such as a hinge metal fitting. The number of parts can be reduced as compared with.

(その他の実施形態)
以上、本発明を好ましい実施形態により説明してきたが、種々の改変が可能である。
(Other embodiments)
Although the present invention has been described with the preferred embodiments, various modifications can be made.

例えば、上記の実施形態では、係合凸部22と係合爪部32とは扉20が開位置にあるときに係合して扉20を起立状態に保持するものとしたが、上記開位置に加えて、それ以外の場所で係合するようにしてもよい。例えば、図示しないが、上記開位置に加えて閉位置近傍でも係合するように構成することにより、扉20の係合部23及び本体カバー30の被係合部35を設けなくても、扉20を閉位置に保持することができる。これにより、従来技術と比較してさらに部品点数を削減することができる。   For example, in the above embodiment, the engagement convex portion 22 and the engagement claw portion 32 are engaged when the door 20 is in the open position to hold the door 20 in an upright position. In addition, it may be engaged at other locations. For example, although not shown, the door is configured to be engaged in the vicinity of the closed position in addition to the open position, so that the door can be provided without providing the engaging portion 23 of the door 20 and the engaged portion 35 of the main body cover 30. 20 can be held in the closed position. Thereby, compared with a prior art, a number of parts can further be reduced.

また、係合凸部22と係合爪部32との係合は、それぞれの先端部にある係合端部22dと係合爪32bとの係合によって実現されるものとしたが、これに限定されない。例えば、係合凸部22と係合爪部32との先端部以外の部分同士が係合するようにしてもよく、例えば、係合凸部22及び係合爪部32のいずれか一方の先端部と、他方の先端部以外の部分とが係合するようにしてもよい。   In addition, the engagement between the engagement convex portion 22 and the engagement claw portion 32 is realized by the engagement between the engagement end portion 22d and the engagement claw 32b at the respective distal ends. It is not limited. For example, portions other than the distal end portions of the engaging convex portion 22 and the engaging claw portion 32 may be engaged with each other, for example, the distal end of either the engaging convex portion 22 or the engaging claw portion 32. You may make it a part and parts other than the other front-end | tip part engage.

本発明は、収納箱において、蝶番装置を使用することなく扉を開いた状態で保持させることができるため、操作部を有する電気機器を収納する収納箱として極めて有用である。   INDUSTRIAL APPLICABILITY Since the storage box can be held with the door open without using a hinge device, the storage box is extremely useful as a storage box for storing an electrical device having an operation unit.
