特開２０１６−１２６３９６号公報Japanese Unexamined Patent Publication No. 2016-126396

セキュリティボックスを小さくしたいというニーズがある。しかしながら、セキュリティボックスを小さくすると、セキュリティボックス内のスペースに余裕が無くなるため、蓋を止める機構（ネジによる結合構造部の大きさ）をなるべく小さくしたい。ここで、樹脂でネジの受け部を作成する構成を採用した場合、ネジの開け閉め回数が増えると、樹脂が磨耗してネジが外れやすくなる問題があった。そこで、市販の汎用のネジやナットを使用し、製造の容易性／コストを満足できる小型の蓋止め機構を提案する。 There is a need to make the security box smaller. However, if the security box is made smaller, there will be no room in the security box, so we want to make the mechanism for stopping the lid (the size of the connecting structure with screws) as small as possible. Here, when a configuration in which the receiving portion of the screw is made of resin is adopted, there is a problem that the resin is worn and the screw is easily removed as the number of times of opening and closing the screw increases. Therefore, we propose a compact lid stopper mechanism that can satisfy the ease of manufacture / cost by using commercially available general-purpose screws and nuts.

本発明は、上述の課題の少なくとも一部を解決するためになされたものであり、以下の形態として実現することが可能である。 The present invention has been made to solve at least a part of the above-mentioned problems, and can be realized as the following forms.

（１）本発明の一形態によれば、セキュリティボックスが提供される。このセキュリティボックスは、蓋と、本体と、を備える。前記蓋と前記本体とのうちの一方である第１部材はｎ角（ｎは３以上の整数）のナットを収納するナット収納部を有し、前記蓋と前記本体とのうちの他方である第２部材はネジを支持するネジ支持部を有し、前記ナット収納部は、前記ナットのｎ個の側面のうちの１つの側面と、前記ナットのネジ穴の向きと平行なｎ個の辺のうちの前記１つの側面と最も離れた辺と、の最短距離に相当する間隔で設けられた互いに対向する一対の第１固定部であって、それぞれの第１固定部は、前記ナットが収納される収納空間を挟んで対向する他方の第１固定部に向かって突出する凸部を有し、前記凸部の外側から前記収納空間に前記ナットが押し込まれたときに、前記一対の第１固定部の間隔が広がって前記ナットの挿入を可能にするスナップフィット構造を有する一対の第１固定部を備え、前記第２部材は、前記本体に前記蓋が閉められたときに、前記一対の第１固定部の前記収納空間の反対側に嵌合して、前記一対の第１固定部の間隔が広がらないように外側から押さえる押さえ部材を有する。
ネジで留めるときには、ネジの回転によりナットが回転し、一対の第１固定部の間隔を広げるため、ナットが収納空間から外れるおそれがある。この形態によれば、蓋が閉められると、ナットの回転により一対の第１固定部の間隔が広がらないように、第２部材の押さえ部材が押さえるため、一対の第１固定部の間隔が広がらずナットが外れにくい。また、蓋が閉められていない場合には、第１固定部がスナップフィット構造を有し、第２部材の押さえ部材が第１固定部を押さえないため、第１固定部が広がり、ナットをナット収納部に収納しやすい。また、ネジやナットとして市販されている汎用のネジやナットを使用できるので製造が容易でありコストも満足できる。 (1) According to one embodiment of the present invention, a security box is provided. This security box includes a lid and a main body. The first member, which is one of the lid and the main body, has a nut storage portion for storing nuts of n angle (n is an integer of 3 or more), and is the other of the lid and the main body. The second member has a screw support portion for supporting the screw, and the nut accommodating portion has one side surface of the n side surfaces of the nut and n sides parallel to the direction of the screw hole of the nut. A pair of first fixing portions facing each other provided at intervals corresponding to the shortest distance between the one side surface and the farthest side, and the nuts are stored in each of the first fixing portions. It has a convex portion that protrudes toward the other first fixed portion that faces the storage space, and when the nut is pushed into the storage space from the outside of the convex portion, the pair of first fixed portions is formed. The second member comprises a pair of first fixing portions having a snap-fit structure that allows the nuts to be inserted by widening the distance between the fixing portions, and the second member is the pair when the lid is closed to the main body. It has a pressing member that is fitted to the opposite side of the storage space of the first fixing portion and is pressed from the outside so that the distance between the pair of first fixing portions is not widened.
When fastening with a screw, the nut rotates due to the rotation of the screw, and the distance between the pair of first fixing portions is widened, so that the nut may come off from the storage space. According to this embodiment, when the lid is closed, the holding member of the second member presses the pair so that the distance between the pair of first fixing portions does not increase due to the rotation of the nut, so that the distance between the pair of first fixing portions becomes wide. The nut does not come off easily. Further, when the lid is not closed, the first fixing portion has a snap-fit structure, and the pressing member of the second member does not press the first fixing portion, so that the first fixing portion expands and the nut is nutted. Easy to store in the storage section. In addition, since general-purpose screws and nuts commercially available can be used as screws and nuts, manufacturing is easy and the cost is satisfactory.

（２）上記形態において、前記ｎは偶数であり、前記一対の第１固定部は、前記ナットの二面幅に相当する間隔で設けられていてもよい。
この形態によれば、ｎが偶数なので、ナットの側面と第１固定部の収納空間側の面とを略平行にでき、ナットを一対の第１固定部によって安定にできる。なお、二面幅の大きさは、ｎ個の側面のうちの１つの側面と、前記ナットのネジ穴の向きと平行なｎ個の辺のうちの前記１つの側面と最も離れた辺との最短距離と等しい。 (2) In the above embodiment, the n is an even number, and the pair of first fixing portions may be provided at intervals corresponding to the width across flats of the nut.
According to this embodiment, since n is an even number, the side surface of the nut and the surface of the first fixing portion on the storage space side can be made substantially parallel, and the nut can be stabilized by the pair of first fixing portions. The size of the width across flats is the size of one of the n side surfaces and the side farthest from the one side surface of the n sides parallel to the direction of the screw hole of the nut. Equal to the shortest distance.

（３）上記形態において、前記凸部は、前記収納空間と反対側に、前記収納空間に収納される前の前記ナットを載置するためのナット載置部を備えていてもよい。
この形態によれば、ナットを収納空間に挿入する前のナットをナット載置部に載置できるので、その後ナットを収納挿入し易く、特にナットが小さい場合には、ナットを無くしにくい。 (3) In the above embodiment, the convex portion may be provided with a nut mounting portion for mounting the nut before being stored in the storage space on the opposite side of the storage space.
According to this form, since the nut before inserting the nut into the storage space can be placed on the nut mounting portion, it is easy to store and insert the nut after that, and it is difficult to lose the nut especially when the nut is small.

（４）上記形態において、前記ナット載置部は、前記ナットの形状に嵌合する凹形状を有していてもよい。
第１固定部に対しナットの側面が合わせやすくなるので、意図しない向きでナットが固定されることが抑制できる。 (4) In the above embodiment, the nut mounting portion may have a concave shape that fits the shape of the nut.
Since the side surface of the nut can be easily aligned with the first fixing portion, it is possible to prevent the nut from being fixed in an unintended direction.

（５）上記形態において、前記ナット収納部は、さらに、ネジ穴の方向において、前記収納空間を挟むように設けられた第２固定部を有してもよい。
この形態によれば、ネジを留めるとき、あるいはネジを外すときに、ナットがネジ穴に沿った方向に移動することを抑制できる。 (5) In the above embodiment, the nut accommodating portion may further have a second fixing portion provided so as to sandwich the accommodating space in the direction of the screw hole.
According to this form, it is possible to prevent the nut from moving in the direction along the screw hole when the screw is fastened or removed.

（６）上記形態において、前記一対第１固定部は、前記収納空間と反対側の基部にリブを有してもよい。
この形態によれば、一対の第１固定部は、収納空間と反対側の基部にリブを有しているので、収納空間と反対側に広がりにくい。 (6) In the above embodiment, the pair-first fixing portion may have a rib at a base portion opposite to the storage space.
According to this form, since the pair of first fixing portions has ribs at the base portion on the side opposite to the storage space, it is difficult to spread to the side opposite to the storage space.

（７）上記形態において、前記第１部材は、さらに前記本体に前記蓋が閉められたときに、前記第１固定部とともに前記押さえ部材を挟む第３固定部を有してもよい。
この形態によれば、第３固定部で押さえ部が広がるのを押さえるので、さらにナットを外れ難くできる。 (7) In the above embodiment, the first member may further have a third fixing portion that sandwiches the holding member together with the first fixing portion when the lid is closed to the main body.
According to this form, since the holding portion is prevented from expanding by the third fixing portion, the nut can be further prevented from coming off.

なお、本発明は、種々の形態で実現することが可能であり、例えば、セキュリティボックスの他、セキュリティボックスのネジ止め構造等の形態で実現することができる。 The present invention can be realized in various forms, for example, in the form of a security box as well as a screwed structure of the security box.

・第１実施形態：
図１は、セキュリティボックス１０の外観を示す説明図である。セキュリティボックス１０は、認証装置を収納し、例えばドアの近傍の壁２０に取り付けられる小型のボックスである。セキュリティボックス１０は、本体１００と、蓋２００とを備えており、蓋２００は、カード検知部２５０を備える。認証を受ける人が、カードをカード検知部２５０にかざすと、認証が行われ、ドアのロックが解錠される。本実施形態では、セキュリティボックス１０は、カードを検知するカード検知部２５０を備えるが、カード検知部２５０以外の検知部、例えば指紋や、手のひらや指の静脈を用いたバイオメトリック認証をするための検知部を備えても良い。 -First embodiment:
FIG. 1 is an explanatory diagram showing the appearance of the security box 10. The security box 10 is a small box that houses an authentication device and is attached to, for example, a wall 20 near a door. The security box 10 includes a main body 100 and a lid 200, and the lid 200 includes a card detection unit 250. When the person to be authenticated holds the card over the card detection unit 250, the authentication is performed and the door lock is unlocked. In the present embodiment, the security box 10 includes a card detection unit 250 that detects a card, but is used for biometric authentication using a detection unit other than the card detection unit 250, such as a fingerprint or a vein of a palm or a finger. A detection unit may be provided.

図２は、セキュリティボックス１０の蓋を開けたときを示す説明図である。図３は、セキュリティボックス１０を斜め下方から見た時の外観を示す説明図である。セキュリティボックス１０は、下部にネジ３００を有し、ネジ３００を緩めることで、蓋２００を開けて、本体１００の内部にアクセスすることができる。本実施形態では、セキュリティボックス１０の上側に蓋２００を回動させるための支点を設け、蓋２００が下から上に開くようになっているが、セキュリティボックス１０の左側または右側に蓋２００を回動させるための支点を設け、蓋２００が左または右に開くようにしてもよい。また、ネジ３００を蓋２００の上下、または左右、あるいは、蓋２００の上下と左右に設け、蓋２００が本体１００から分離するように構成されていてもよい。 FIG. 2 is an explanatory diagram showing a case where the lid of the security box 10 is opened. FIG. 3 is an explanatory view showing the appearance of the security box 10 when viewed from diagonally below. The security box 10 has a screw 300 at the bottom, and by loosening the screw 300, the lid 200 can be opened to access the inside of the main body 100. In the present embodiment, a fulcrum for rotating the lid 200 is provided on the upper side of the security box 10, and the lid 200 opens from the bottom to the top. However, the lid 200 is rotated on the left side or the right side of the security box 10. A fulcrum for movement may be provided so that the lid 200 opens to the left or right. Further, the screws 300 may be provided above and below or to the left and right of the lid 200, or above and below and to the left and right of the lid 200 so that the lid 200 is separated from the main body 100.

図４は、図３の４−４断面を示す説明図である。本実施形態では、ネジ３００は、蓋２００の内側に設けられたネジ支持部２１０によって回転可能に取り付けられている。ネジ支持部２１０は、例えば樹脂で形成されている。ネジ３００は、小さいと無くし易いが、ネジ３００がネジ支持部２１０に取り付けられることで、無くし難くできる。ネジ３００としては、市販の汎用のネジが使用可能である。本実施形態のネジ３００は、「ボルト」とも呼ぶ。 FIG. 4 is an explanatory view showing a 4-4 cross section of FIG. In the present embodiment, the screw 300 is rotatably attached by a screw support portion 210 provided inside the lid 200. The screw support portion 210 is made of, for example, resin. The screw 300 is easy to lose if it is small, but it can be difficult to lose by attaching the screw 300 to the screw support portion 210. As the screw 300, a commercially available general-purpose screw can be used. The screw 300 of this embodiment is also referred to as a "bolt".

図５は、ナット３１０と、ナット収納部１０５の概略構成を示す説明図である。ナット収納部１０５は、本体１００に形成されており、互いに対向する一対の第１固定部１１０と、互いに対向する２つの第２固定部１２０，１２５とを備える。ナット収納部１０５は、一対の第１固定部１１０と、２つの第２固定部１２０，１２５とに囲われて形成される収納空間１５０に、ナット３１０を収納する。本実施形態においては、ナット３１０として、大きさが数ミリメートル以下の小さな六角ナットが用いられる。六角ナットであれば、市販の汎用のナットが使用可能である。但し、ｎ角（ｎは３以上の整数）のナットであればよい。 FIG. 5 is an explanatory view showing a schematic configuration of the nut 310 and the nut accommodating portion 105. The nut accommodating portion 105 is formed in the main body 100, and includes a pair of first fixing portions 110 facing each other and two second fixing portions 120 and 125 facing each other. The nut storage portion 105 stores the nut 310 in a storage space 150 formed by being surrounded by a pair of first fixing portions 110 and two second fixing portions 120 and 125. In the present embodiment, as the nut 310, a small hexagon nut having a size of several millimeters or less is used. If it is a hexagon nut, a commercially available general-purpose nut can be used. However, any nut may be n-angle (n is an integer of 3 or more).

２つの第１固定部１１０は、樹脂製の部材であり、ナット３１０の二面幅に相当する間隔で設けられている。六角ナットの場合、ナット３１０の側面を、第１固定部１１０の収納空間１５０側の面と略平行にできるので、第１固定部１１０でナット３１０を安定に保持できる。この点は、ｎが偶数のｎ角のナットでも同様である。第１固定部１１０のそれぞれは、本体１００に固定される基部１１６と、基部１１６の反対側において、対向する他方の第１固定部１１０に向かって突出する凸部１１２を備える。２つの凸部１１２の頂部間の間隔は、ナット３１０における二面幅よりも小さい。そのため、凸部１１２は、収納空間１５０に収納されたナット３１０を、ｚ方向に外れ難くする。凸部１１２の収納空間１５０と反対側（ｚ方向）には、収納空間１５０に収納される前のナット３１０を載置するためのナット載置部１１４が形成されている。ナット載置部１１４は、その上にナット３１０を載置したときに、ナット３１０が安定するようにナット３１０の形状と嵌合する凹んだ凹形状を有している。また、ナット３１０の収納空間１５０への挿入後に、第１固定部１１０に対しナット３１０の側面が合わせやすくなる。ナット載置部１１４は、凹んだ凹形状の他、収納空間１５０と反対側に突出する突起によりナット３１０を挟んで安定化させる形状であっても良い。なお、ナット載置部１１４は無くても良い。基部１１６は、収納空間１５０と反対側にリブ１１８を備えている。リブ１１８を備えることで、第１固定部１１０を広がりにくくできる。ただし、基部１１６は、リブ１１８を備えていなくても良い。また、第１固定部１１０の収納空間１５０と反対側（ｘ方向の外側）には、第１固定部１１０が広がることができる空間が空いている。 The two first fixing portions 110 are resin members and are provided at intervals corresponding to the width across flats of the nut 310. In the case of a hexagon nut, since the side surface of the nut 310 can be made substantially parallel to the surface of the first fixing portion 110 on the storage space 150 side, the nut 310 can be stably held by the first fixing portion 110. This point is the same for nuts having an even number of n angles. Each of the first fixing portions 110 includes a base portion 116 fixed to the main body 100, and a convex portion 112 protruding toward the other first fixing portion 110 facing the base portion 116 on the opposite side of the base portion 116. The distance between the tops of the two protrusions 112 is smaller than the width across flats in the nut 310. Therefore, the convex portion 112 makes it difficult for the nut 310 stored in the storage space 150 to come off in the z direction. On the opposite side (z direction) of the convex portion 112 from the storage space 150, a nut mounting portion 114 for mounting the nut 310 before being stored in the storage space 150 is formed. The nut mounting portion 114 has a concave concave shape that fits with the shape of the nut 310 so that the nut 310 is stable when the nut 310 is mounted on the nut mounting portion 114. Further, after the nut 310 is inserted into the storage space 150, the side surface of the nut 310 can be easily aligned with the first fixing portion 110. The nut mounting portion 114 may have a concave shape, or may have a shape in which the nut 310 is sandwiched and stabilized by a protrusion protruding on the opposite side of the storage space 150. The nut mounting portion 114 may not be provided. The base 116 is provided with ribs 118 on the opposite side of the storage space 150. By providing the rib 118, the first fixing portion 110 can be made difficult to spread. However, the base 116 does not have to include the rib 118. Further, on the side opposite to the storage space 150 of the first fixed portion 110 (outside in the x direction), there is a space in which the first fixed portion 110 can be expanded.

２つの第２固定部１２０，１２５は、樹脂製の部材であり、ナット３１０におけるネジ穴３１５の方向（ｙ方向）と垂直な２つの対面の対面間の寸法の間隔で設けられている。２つの第２固定部１２０，１２５の間にナット３１０を嵌め込むことができる。２つの第２固定部１２０，１２５は、ネジ３００のナット３１０への挿入時に、ナット３１０がネジ穴３１５に沿った方向に移動することを抑制する。第２固定部１２０，１２５のｚ方向の高さは、収納空間１５０に収納されたナット３１０のネジ穴３１５にネジ３００が挿入できるように、ネジ穴３１５のｚ方向の位置よりも低い。なお、ネジ穴３１５の方向から見てネジ穴３１５と重ならない位置においては、第２固定部１２０，１２５の高さは、ネジ穴３１５のｚ方向の位置よりも高くても良い。なお本実施形態では、２つの第２固定部１２０，１２５は、形状が少し異なるため、異なる符号を付しているが、同じ形状としてもよい。 The two second fixing portions 120 and 125 are resin members, and are provided at a dimensional interval between two facing surfaces perpendicular to the direction (y direction) of the screw hole 315 in the nut 310. The nut 310 can be fitted between the two second fixing portions 120 and 125. The two second fixing portions 120, 125 prevent the nut 310 from moving in the direction along the screw hole 315 when the screw 300 is inserted into the nut 310. The height of the second fixing portions 120, 125 in the z direction is lower than the position of the screw hole 315 in the z direction so that the screw 300 can be inserted into the screw hole 315 of the nut 310 housed in the storage space 150. The height of the second fixing portions 120 and 125 may be higher than the position of the screw hole 315 in the z direction at a position where the screw hole 315 does not overlap with the screw hole 315 when viewed from the direction of the screw hole 315. In the present embodiment, the two second fixing portions 120 and 125 are slightly different in shape and therefore have different reference numerals, but they may have the same shape.

図６は、図５の状態でナット３１０をナット載置部１１４に載置した状態を示す説明図である。ナット載置部１１４が設けられていると、図６に示すように、収納空間１５０に収納される前のナット３１０をナット載置部１１４に一旦載置できるので、その後、ナットを収納空間１５０に収納しやすい。特に小さいナット３１０を挿入する場合には、ナット載置部１１４を備えることが好ましい。挿入前のナット３１０を安定させることができ、ナット３１０を無くしにくくできる。 FIG. 6 is an explanatory view showing a state in which the nut 310 is mounted on the nut mounting portion 114 in the state of FIG. When the nut mounting portion 114 is provided, as shown in FIG. 6, the nut 310 before being stored in the storage space 150 can be temporarily mounted on the nut mounting portion 114, and then the nut can be stored in the storage space 150. Easy to store in. Especially when inserting a small nut 310, it is preferable to provide a nut mounting portion 114. The nut 310 before insertion can be stabilized, and the nut 310 can be difficult to lose.

図７は、ナット３１０を収納空間１５０に挿入した状態を示す説明図である。ナット３１０が、凸部１１２の外側からマイナスのｚ方向に押され収納空間１５０に押し込まれると、一対の第１固定部１１０は、ナット３１０に押され、収納空間１５０と反対側（ｘ方向）に変形して一対の第１固定部１１０の間隔が広がりナット３１０を収納空間１５０に収納する。第１固定部１１０は、ナット３１０が収納空間１５０に収納されると、第１固定部１１０の有する弾性により、間隔が広がった状態から元の状態にもどる。第１固定部１１０は、元の状態に戻ると、凸部１１２により、ナット３１０を外れに難くする。すなわち、第１固定部１１０は、ナット３１０を嵌め込んで外れないようにするスナップフィット構造を有する。また、第１固定部１１０の凸部１１２の間隔は、ナット３１０の大きさよりも小さいので、ナット３１０を外そうとする力が加わらない限り、ナット３１０は収納空間１５０から外れない。ナット３１０を収納空間１５０からプラスのｚ方向に移動させると、第１固定部１１０は、ナット３１０に押され、収納空間１５０と反対側（ｘ方向）に広がりナット３１０を収納空間１５０から外すことができる。 FIG. 7 is an explanatory view showing a state in which the nut 310 is inserted into the storage space 150. When the nut 310 is pushed from the outside of the convex portion 112 in the negative z direction and pushed into the storage space 150, the pair of first fixing portions 110 is pushed by the nut 310 and on the opposite side (x direction) from the storage space 150. The distance between the pair of first fixing portions 110 is widened, and the nut 310 is stored in the storage space 150. When the nut 310 is stored in the storage space 150, the first fixing portion 110 returns from the widened state to the original state due to the elasticity of the first fixing portion 110. When the first fixing portion 110 returns to the original state, the convex portion 112 makes it difficult for the nut 310 to come off. That is, the first fixing portion 110 has a snap-fit structure that fits the nut 310 and prevents it from coming off. Further, since the distance between the convex portions 112 of the first fixing portion 110 is smaller than the size of the nut 310, the nut 310 cannot be removed from the storage space 150 unless a force for removing the nut 310 is applied. When the nut 310 is moved from the storage space 150 in the positive z direction, the first fixing portion 110 is pushed by the nut 310 and spreads in the opposite side (x direction) to the storage space 150 to remove the nut 310 from the storage space 150. Can be done.

図８は、図６と図７の状態を、ネジ穴３１５の方向（ｙ方向）から見た図である。実線がナット３１０をナット載置部１１４に載置した図６の状態であり、破線がナット３１０を収納空間１５０に収納した図７の状態である。ナット３１０が収納空間１５０に挿入されるときに、第１固定部１１０は、一旦矢印で示す方向（ｘ方向）に広がり、ナット３１０の収納後、元の状態に戻る。また、第１固定部１１０が有するスナップフィット構造により収納空間１５０に収納されたナット３１０は、凸部１１２により、収納空間１５０から外れにくい。 FIG. 8 is a view of the states of FIGS. 6 and 7 as viewed from the direction (y direction) of the screw hole 315. The solid line is the state of FIG. 6 in which the nut 310 is placed on the nut mounting portion 114, and the broken line is the state of FIG. 7 in which the nut 310 is stored in the storage space 150. When the nut 310 is inserted into the storage space 150, the first fixing portion 110 once expands in the direction indicated by the arrow (x direction), and after the nut 310 is stored, returns to the original state. Further, the nut 310 housed in the storage space 150 due to the snap-fit structure of the first fixing portion 110 is hard to come off from the storage space 150 due to the convex portion 112.

図９は、蓋２００を開けたときのナット収納部１０５近傍の構成を示す説明図である。図１０は、蓋２００を閉めたときのナット収納部１０５近傍の構成を示す説明図である。図９、１０では、説明の都合上、ネジ３００、ネジ支持部２１０及び手前側の第２固定部１２０を図示していない。蓋２００は、樹脂製の押さえ部材２３０を有する。押さえ部材２３０は、２つの第１固定部１１０をｘ方向の両側から挟みこむことができる間隔で設けられている。蓋２００が閉められると、図１０に示すように、第１固定部１１０を、凸部１１２の反対側（ｘ方向）から挟むような位置に嵌合する。押さえ部材２３０は、蓋２００が閉められると、本体１００の第１固定部１１０が収納空間１５０（図５等）と反対側（ｘ方向）に広がらないように、第１固定部１１０の外側（ｘ方向）から押さえる。押さえ部材２３０がない場合には、ネジ３００の回転でナット３１０が回転し、第１固定部１１０をｘ方向に広げる。その結果、ナット３１０が、収納空間１５０から外れてしまうおそれがある。これに対し、押さえ部材２３０があると、ネジ３００をナット３１０のネジ穴３１５に挿入するときに、ネジ３００の回転でナット３１０が回転して、第１固定部１１０をｘ方向に広げようとしても、押さえ部材２３０によって、一対の
第１固定部１１０の間隔は広がらない。そのため、ネジ３００を留めるときに、ナット３１０を収納空間１５０から外れ難くできる。 FIG. 9 is an explanatory view showing a configuration in the vicinity of the nut storage portion 105 when the lid 200 is opened. FIG. 10 is an explanatory view showing a configuration in the vicinity of the nut accommodating portion 105 when the lid 200 is closed. In FIGS. 9 and 10, for convenience of explanation, the screw 300, the screw support portion 210, and the second fixing portion 120 on the front side are not shown. The lid 200 has a resin pressing member 230. The pressing member 230 is provided at intervals so that the two first fixing portions 110 can be sandwiched from both sides in the x direction. When the lid 200 is closed, as shown in FIG. 10, the first fixing portion 110 is fitted at a position where it is sandwiched from the opposite side (x direction) of the convex portion 112. When the lid 200 is closed, the pressing member 230 is placed outside the first fixing portion 110 (in the x direction) so that the first fixing portion 110 of the main body 100 does not spread to the opposite side (x direction) of the storage space 150 (FIG. 5, etc.). Hold down from the x direction). When there is no pressing member 230, the nut 310 is rotated by the rotation of the screw 300, and the first fixing portion 110 is widened in the x direction. As a result, the nut 310 may come off the storage space 150. On the other hand, when the holding member 230 is provided, when the screw 300 is inserted into the screw hole 315 of the nut 310, the nut 310 is rotated by the rotation of the screw 300 to try to expand the first fixing portion 110 in the x direction. However, the space between the pair of first fixing portions 110 is not widened by the pressing member 230. Therefore, when the screw 300 is fastened, the nut 310 can be prevented from coming off from the storage space 150.

蓋２００が開けられると、押さえ部材２３０は、図９に示すように、蓋２００とともに移動し、第１固定部１１０の凸部１１２と反対側に位置しなくなる。その結果、第１固定部１１０は、押さえ部材２３０に押さえられないので、凸部１１２と反対側（ｘ方向）に広がることが可能となる。図９に示す状態では、第１固定部１１０は、ｘ方向に広がることができるので、ナット３１０を取り外すことが可能である。押さえ部材２３０は、樹脂の他、金属により構成されていても良い。 When the lid 200 is opened, the pressing member 230 moves together with the lid 200 and is no longer located on the side opposite to the convex portion 112 of the first fixing portion 110, as shown in FIG. As a result, since the first fixing portion 110 is not pressed by the pressing member 230, it can be expanded on the opposite side (x direction) from the convex portion 112. In the state shown in FIG. 9, since the first fixing portion 110 can expand in the x direction, the nut 310 can be removed. The pressing member 230 may be made of metal in addition to resin.

このように、本実施形態によれば、本体１００は、ナット３１０の二面幅の相当する間隔を開けて互いに対向して配置される一対の第１固定部１１０を有し、それぞれの第１固定部１１０は、ナット３１０が収納される収納空間１５０の第１固定部の基部１１６と反対側において対向する第１固定部１１０に向かって突出する凸部１１２を有している。第１固定部１１０は、凸部１１２の外側からナット３１０が押し込まれたときに、第１固定部１１０の間隔が広がってナット３１０の挿入を可能にするスナップフィット構造を有しているので、ナット３１０を容易に本体１００の収納空間１５０に収納できる。凸部１１２は、ナット３１０が収納空間１５０に収納された状態で、ナット３１０を収納空間１５０から外れ難くする。さらに、本体１００に蓋２００を閉めると、押さえ部材２３０が、２つの第１固定部１１０の収納空間１５０の反対側に嵌まり、第１固定部１１０の間隔が広がらないように外側から押さえる。ここで、蓋２００を閉めてネジ３００をナット３１０のネジ穴３１５に挿入して蓋を止めようとするとき、ネジ３００の回転によりナット３１０が回転し、第１固定部１１０を広げようとする。しかし、本実施形態では、押さえ部材２３０が、第１固定部１１０の間隔が広がらないように外側から押さえるので、ナット３１０を収納空間１５０から外れ難くできる。 As described above, according to the present embodiment, the main body 100 has a pair of first fixing portions 110 which are arranged so as to face each other with a corresponding interval of the width across flats of the nut 310, and the first of each. The fixing portion 110 has a convex portion 112 that protrudes toward the first fixing portion 110 that faces the base portion 116 of the first fixing portion of the storage space 150 in which the nut 310 is housed. Since the first fixing portion 110 has a snap-fit structure that allows the nut 310 to be inserted by widening the space between the first fixing portions 110 when the nut 310 is pushed in from the outside of the convex portion 112. The nut 310 can be easily stored in the storage space 150 of the main body 100. The convex portion 112 makes it difficult for the nut 310 to come off from the storage space 150 in a state where the nut 310 is stored in the storage space 150. Further, when the lid 200 is closed to the main body 100, the pressing member 230 fits on the opposite side of the storage space 150 of the two first fixing portions 110, and presses from the outside so that the distance between the first fixing portions 110 does not widen. Here, when the lid 200 is closed and the screw 300 is inserted into the screw hole 315 of the nut 310 to stop the lid, the nut 310 is rotated by the rotation of the screw 300 to expand the first fixing portion 110. .. However, in the present embodiment, since the pressing member 230 presses from the outside so that the distance between the first fixing portions 110 does not widen, the nut 310 can be prevented from coming off from the storage space 150.

本実施形態によれば、ナット載置部１１４を備えるので、収納空間１５０に収納する前のナット３１０をナット載置部１１４に載置することで、ナット３１０を安定させ、その後、ナット３１０を収納空間１５０に押し込むことで、ナット３１０を容易に収納空間１５０に収納できる。 According to the present embodiment, since the nut mounting portion 114 is provided, the nut 310 before being stored in the storage space 150 is mounted on the nut mounting portion 114 to stabilize the nut 310, and then the nut 310 is placed. By pushing into the storage space 150, the nut 310 can be easily stored in the storage space 150.

本実施形態によれば、ネジ穴３１５の方向において、収納空間１５０をｙ方向から挟むように設けられた第２固定部１２０，１２５を有する。その結果、ネジ３００をナット３１０に挿入するときに、ナット３１０がｙ方向に移動しないように、第２固定部１２０，１２５によってナット３１０を固定できる。 According to the present embodiment, there are second fixing portions 120, 125 provided so as to sandwich the storage space 150 from the y direction in the direction of the screw hole 315. As a result, when the screw 300 is inserted into the nut 310, the nut 310 can be fixed by the second fixing portions 120 and 125 so that the nut 310 does not move in the y direction.

本実施形態によれば、第１固定部１１０は、収納空間１５０と反対側の基部１１６にリブ１１８を有する。リブ１１８を備えることで、第１固定部１１０を広がり難くでき、収納空間１５０に収納したナット３１０を外れ難くできる。 According to the present embodiment, the first fixing portion 110 has a rib 118 at the base portion 116 opposite to the storage space 150. By providing the rib 118, the first fixing portion 110 can be made difficult to spread, and the nut 310 stored in the storage space 150 can be made difficult to come off.

・第２実施形態：
図１１は、第２実施形態におけるナット３１０と、ナット収納部１０５の概略構成を示す説明図である。第１実施形態との違いは、第３固定部１３０を備える点である、第３固定部１３０は、第１固定部１１０の収納空間１５０と反対側に、第１固定部１１０と所定の間隔を開けて設けられており、第３固定部１３０と第１固定部１１０との間に押さえ部材２３０（図９）を挿入可能である。 -Second embodiment:
FIG. 11 is an explanatory view showing a schematic configuration of the nut 310 and the nut accommodating portion 105 in the second embodiment. The difference from the first embodiment is that the third fixed portion 130 is provided. The third fixed portion 130 has a predetermined distance from the first fixed portion 110 on the opposite side of the storage space 150 of the first fixed portion 110. The pressing member 230 (FIG. 9) can be inserted between the third fixing portion 130 and the first fixing portion 110.

図１２は、第２実施形態における蓋２００を閉めたときのナット収納部１０５近傍の構成を示す説明図である。第１実施形態では、ナット３１０の回転により第１固定部１１０が広がらないように、押さえ部材２３０が第１固定部１１０を外側から押さえた。第２実施形態では、さらに、押さえ部材２３０が広がらないように、第３固定部１３０が、押さえ部材２３０を押さえる。したがって、蓋２００を閉めたとき第１実施形態よりもさらに、ナット３１０を外れ難くできる。なお、蓋２００を開けた時には、第１固定部１１０は、広がることができるため、第１実施形態と同様に、ナット３１０を収納空間１５０に容易に嵌め込み、あるいは、ナット３１０を収納空間１５０から容易に取り外すことができる。すなわち、本実施形態によれば、蓋２００を閉めた状態では、ナット３１０を外れ難くし、蓋２００を開けた状態では、ナット３１０は収納空間１５０に嵌め込まれているが、ナット３１０外そうとすれば容易に外すことができ、ナット３１０の交換を容易にできる。 FIG. 12 is an explanatory view showing a configuration in the vicinity of the nut accommodating portion 105 when the lid 200 in the second embodiment is closed. In the first embodiment, the pressing member 230 presses the first fixing portion 110 from the outside so that the first fixing portion 110 does not spread due to the rotation of the nut 310. In the second embodiment, the third fixing portion 130 further presses the pressing member 230 so that the pressing member 230 does not spread. Therefore, when the lid 200 is closed, the nut 310 can be made more difficult to come off than in the first embodiment. Since the first fixing portion 110 can be expanded when the lid 200 is opened, the nut 310 can be easily fitted into the storage space 150 or the nut 310 can be fitted from the storage space 150 as in the first embodiment. It can be easily removed. That is, according to the present embodiment, the nut 310 is difficult to remove when the lid 200 is closed, and the nut 310 is fitted in the storage space 150 when the lid 200 is opened, but the nut 310 is to be removed. This can be easily removed and the nut 310 can be easily replaced.

上記実施形態では、本体１００と蓋２００のうち、一方の本体１００がナット３１０を収納するナット収納部１０５を有する第１部材であり、他方の蓋２００がネジ３００を支持するネジ支持部２１０を有する第２部材であるとして説明したが、逆に、本体１００がネジ３００を支持するネジ支持部２１０を有する第２部材であり、蓋２００がナット３１０を収納するナット収納部１０５を有する第１部材であるとして構成してもよい。 In the above embodiment, of the main body 100 and the lid 200, one main body 100 is the first member having a nut storage portion 105 for accommodating the nut 310, and the other lid 200 has a screw support portion 210 for supporting the screw 300. Although it has been described as having the second member, conversely, the main body 100 is the second member having the screw support portion 210 for supporting the screw 300, and the lid 200 is the first member having the nut storage portion 105 for storing the nut 310. It may be configured as a member.

上記実施形態では、ナット３１０がネジ穴３１５の方向に移動しないように、第２固定部１２０，１２５を用いてナット３１０を固定している。第２固定部１２０，１２５を設ける代わりに、第１固定部１１０のネジ穴３１５の方向と平行な方向の大きさを、ナット３１０のネジ穴３１５の方向と平行な方向の大きさよりも大きくし、第１固定部１１０に、ナット３１０をネジ穴３１５の方向の両側から挟むように収納空間１５０方向に突出するフランジを設けても良い。フランジによりナット３１０のネジ穴３１５に沿った方向への移動を抑制できる。 In the above embodiment, the nut 310 is fixed by using the second fixing portions 120 and 125 so that the nut 310 does not move in the direction of the screw hole 315. Instead of providing the second fixing portions 120 and 125, the size in the direction parallel to the direction of the screw hole 315 of the first fixing portion 110 is made larger than the size in the direction parallel to the direction of the screw hole 315 of the nut 310. The first fixing portion 110 may be provided with a flange that projects in the storage space 150 direction so as to sandwich the nut 310 from both sides in the direction of the screw hole 315. The flange can prevent the nut 310 from moving in the direction along the screw hole 315.

上記実施形態では、ナット３１０として六角ナットを用いたが、三角ナット、四角ナット、五角ナット、七角ナットなどのｎ角ナット（ｎは３以上の整数）であってもよい。なお、ｎは偶数であることが好ましい。ｎが偶数の場合、２つの第１固定部１１０は、ナット３１０の二面幅に相当する間隔で設けられているので、ナット３１０の側面と第１固定部１１０の収納空間１５０側の面とは略平行となり、ナット３１０を一対の第１固定部１１０で固定しやすい。なお、ｎが奇数の場合には、２つの第１固定部１１０は、ナット３１０のｎ個の側面のうちの１つの側面と、ナット３１０のネジ穴３１５の向きと平行なｎ個の辺のうちの１つの側面と最も離れた辺との最短距離に相当する間隔で設けられている。こうすれば、ナット３１０の向きを一定の向きに固定できる。ここで、ｎが偶数のときのナット３１０の二面幅は、ナット３１０のｎ個の側面のうちの１つの側面と、ナット３１０のネジ穴３１５の向きと平行なｎ個の辺のうちの１つの側面と最も離れた辺との最短距離と等しい。従って、ｎが奇数、偶数のいずれであっても、一対の第１固定部１１０は、ナット３１０のｎ個の側面のうちの１つの側面と、ナット３１０のネジ穴３１５の向きと平行なｎ個の辺のうちの１つの側面と最も離れた辺と、の最短距離に相当する間隔で設けられていると言える。 In the above embodiment, the hexagon nut is used as the nut 310, but an n-side nut (n is an integer of 3 or more) such as a triangular nut, a square nut, a pentagon nut, and a hex nut may be used. It is preferable that n is an even number. When n is an even number, the two first fixing portions 110 are provided at intervals corresponding to the width across flats of the nut 310, so that the side surface of the nut 310 and the surface of the first fixing portion 110 on the storage space 150 side Are substantially parallel, and the nut 310 can be easily fixed by the pair of first fixing portions 110. When n is an odd number, the two first fixing portions 110 are formed on one side surface of the n side surfaces of the nut 310 and n sides parallel to the direction of the screw hole 315 of the nut 310. It is provided at an interval corresponding to the shortest distance between one of the side surfaces and the farthest side. In this way, the orientation of the nut 310 can be fixed in a fixed orientation. Here, the width across flats of the nut 310 when n is an even number is one of the n side surfaces of the nut 310 and the n sides parallel to the direction of the screw hole 315 of the nut 310. Equal to the shortest distance between one side and the farthest side. Therefore, regardless of whether n is an odd number or an even number, the pair of first fixing portions 110 is n parallel to one side surface of the n side surfaces of the nut 310 and the direction of the screw hole 315 of the nut 310. It can be said that they are provided at intervals corresponding to the shortest distance between one side surface of the individual sides and the farthest side.
