Description
本考案は、支持脚及びこれを備えたコットに関する。 The present invention relates to a support leg and a cot provided with the support leg.
下記特許文献１には従来のコットが記載されている。このベッドは、可撓性を有する生地で構成された寝床部と、第１、第２支持ポールと、複数の支持脚とを備えている。寝床部の短手方向の両端部には、第１、第２スリーブが各々設けられている。この第１、第２スリーブ内に第１、第２支持ポールが挿入されている。第１、第２スリーブには、その長手方向に間隔をあけて複数の第１、第２切り欠きが設けられている。各支持脚は、第１端部及び第２端部を有する略Ｕ字状の脚本体と、第１接続部と、第２接続部とを有している。第１接続部は、脚本体の第１端部に固定されており且つ外向きに開放された略Ｃ字状の第１フックを有する。第２接続部は、脚本体の第２端部に枢動可能に連結されたレバー部と、このレバー部の先端に設けられており且つ第１フックと逆向きに開放された略Ｃ字状の第２フックとを有している。 The following patent document 1 describes a conventional cot. The bed includes a bed portion made of flexible fabric, first and second support poles, and a plurality of support legs. First and second sleeves are provided at both ends of the bed portion in the short direction. First and second support poles are inserted into the first and second sleeves. The first and second sleeves are provided with a plurality of first and second notches spaced apart in the longitudinal direction. Each support leg has a substantially U-shaped leg body having a first end and a second end, a first connection portion, and a second connection portion. The first connecting portion has a substantially C-shaped first hook that is fixed to the first end portion of the leg main body and opened outward. The second connecting portion is a lever portion that is pivotally connected to the second end portion of the leg body, and a substantially C-shape that is provided at the tip of the lever portion and is opened in the direction opposite to the first hook. The second hook.
支持脚のレバー部が内側に枢動され且つ第２フックが第１フック側に近づいた状態で、第１フックが第１スリーブの第１切り欠きを通じて第１スリーブ内の第１支持ポールに引っ掛けられると共に、第２フックが第２スリーブの第２切り欠きを通じて第２スリーブ内の第２支持ポールに引っ掛けられる。その後、レバー部を外側に枢動させ、第２フックが第１フックから離反することによって、第１、第２支持ポールが互いに離反し、寝床部が緊張する。このように従来のコットが組み立てられている。以下、この組立時の支持脚の状態を拡張状態という。 With the lever portion of the support leg pivoted inward and the second hook approaching the first hook side, the first hook hooks on the first support pole in the first sleeve through the first notch of the first sleeve. The second hook is hooked on the second support pole in the second sleeve through the second notch of the second sleeve. Thereafter, the lever portion is pivoted outward, and the second hook is separated from the first hook, whereby the first and second support poles are separated from each other, and the bed portion is tensioned. Thus, the conventional cot is assembled. Hereinafter, the state of the support leg at the time of assembly is referred to as an expanded state.
上記した従来のコットは、支持脚の拡張状態が不用意に解除される恐れがある。なぜなら、レバー部が脚本体の第２端部に枢動可能に連結された構成であるため、拡張状態で、第２フックに対して内側への外力が加えられると、レバー部が内側に枢動して第２フックが第１フック側に移動し、第１、第２支持ポールが互いに近づいて寝床部の緊張が解除されるリスクがあるからである。 In the conventional cot described above, the extended state of the support legs may be inadvertently released. This is because the lever portion is pivotally connected to the second end portion of the leg body so that when the external force is applied to the second hook in the expanded state, the lever portion is pivoted inward. This is because there is a risk that the second hook moves to the first hook side, the first and second support poles approach each other, and the tension of the bed portion is released.
本考案は、拡張状態が不用意に解除される可能性を低減できる支持脚及びこれを用いたコットを提供する。 The present invention provides a support leg that can reduce the possibility that the expanded state is inadvertently released, and a cot using the support leg.
上記課題を解決するために、本考案の一態様に係る支持脚は、略Ｕ字状であって、略Ｌ字状の第１部と、当該支持脚の幅方向である第１方向において第１部と逆向きの略Ｌ字状の第２部と、枢軸部と、スライドロックを備えている。第１部は、第１水平部と、第１水平部から第２方向に起立した第１起立部と、この第１起立部の先端に設けられた第１留め具とを有する。第２方向は、第１方向に略直交している。第２部は、第２水平部と、この第２水平部から第２方向に起立した第２起立部と、第２起立部の先端に設けられた第２留め具とを有しており、且つ第２水平部が第２方向又は第３方向において第１水平部に重なるように配置されている。第３方向は、第１方向及び第２方向に略直交している。枢軸部は、拡張位置と縮小位置との間で、第２部を第１部に直接的又は間接的に枢動可能に連結している。拡張位置は、第１水平部と第２水平部とが略平行に配置され且つ第１留め具から第２留め具までの第１方向の距離が第１距離となる位置である。縮小位置は、第２水平部が第１水平部に対して傾斜し且つ第１留め具から第２留め具までの第１方向の距離が第１距離よりも短い第２距離となる位置である。スライドロックは、第１水平部にスライド自在に設けられている。第２部が第１部に対して拡張位置に位置する状態で、スライドロックが第２部側に移動して第２水平部をロックする一方、スライドロックが第２水平部をロックした状態からスライドロックが第１部側に移動することにより前記ロックが解除される。 In order to solve the above-described problem, a support leg according to an aspect of the present invention is substantially U-shaped, and has a first portion that is substantially L-shaped and a first direction that is a width direction of the support leg. A substantially L-shaped second part opposite to the first part, a pivot part, and a slide lock are provided. The first part includes a first horizontal part, a first standing part that rises in the second direction from the first horizontal part, and a first fastener provided at a tip of the first standing part. The second direction is substantially orthogonal to the first direction. The second part has a second horizontal part, a second standing part rising from the second horizontal part in the second direction, and a second fastener provided at the tip of the second standing part, The second horizontal portion is disposed so as to overlap the first horizontal portion in the second direction or the third direction. The third direction is substantially orthogonal to the first direction and the second direction. The pivot portion pivotally connects the second portion to the first portion directly or indirectly between the expanded position and the contracted position. The extended position is a position where the first horizontal portion and the second horizontal portion are arranged substantially in parallel and the distance in the first direction from the first fastener to the second fastener is the first distance. The reduced position is a position where the second horizontal portion is inclined with respect to the first horizontal portion and the distance in the first direction from the first fastener to the second fastener is a second distance shorter than the first distance. . The slide lock is slidably provided on the first horizontal portion. In a state where the second part is located at the extended position with respect to the first part, the slide lock moves to the second part side to lock the second horizontal part, while the slide lock locks the second horizontal part. When the slide lock moves to the first part side, the lock is released.
このような態様の支持脚による場合、スライドロックが第１水平部にスライド自在に設けられおり、このスライドロックが、第２部が第１部に対して拡張位置に位置する状態で第２部側に移動して第２水平部をロックしているため、仮に第１部及び／又は第２部に外力が加わったとしても、第２部が第１部に対して拡張位置から縮小位置に枢軸する可能性（すなわち、支持脚の拡張状態が解除される可能性）が低減される。 In the case of the support leg in such a mode, the slide lock is slidably provided on the first horizontal part, and the second part is positioned in the extended position with respect to the first part. Since the second horizontal part is locked by moving to the side, even if an external force is applied to the first part and / or the second part, the second part changes from the expanded position to the reduced position with respect to the first part. The possibility of pivoting (i.e. the possibility that the extended state of the support leg is released) is reduced.
スライドロックは、第２部の第２水平部に対して接近及び離反可能な構成とすることが可能である。スライドロックには、このスライドロックが第２水平部に接近する方向に開口した係合孔が設けられた構成とすることが可能である。第２部が第１部に対して拡張位置に位置する状態で、スライドロックが第２水平部に接近して第２水平部が係合孔に嵌合することによりロックを行う一方、第２水平部が係合孔に嵌合した状態からスライドロックが第２水平部から離反することにより嵌合が解除される構成とすることが可能である。 The slide lock can be configured to be able to approach and leave the second horizontal portion of the second portion. The slide lock may have a configuration in which an engagement hole opened in a direction in which the slide lock approaches the second horizontal portion. While the second part is positioned in the extended position with respect to the first part, the slide lock approaches the second horizontal part and the second horizontal part is fitted into the engagement hole to perform locking. It is possible to adopt a configuration in which the fitting is released when the slide lock is separated from the second horizontal portion from the state where the horizontal portion is fitted in the engagement hole.
又は、スライドロック及び第２水平部の何れか一方には、係合凸部が設けられ、他方には係合孔が設けられた構成とすることが可能である。第２部が第１部に対して拡張位置に位置する状態で、スライドロックが第２部側に移動して係合凸部が係合孔に嵌合することによりロックを行う一方、係合凸部が係合孔に嵌合した状態からスライドロックが第１部側に移動することにより嵌合が解除される構成とすることが可能である。 Alternatively, either one of the slide lock and the second horizontal portion may be provided with an engagement convex portion, and the other may be provided with an engagement hole. While the second part is located at the extended position with respect to the first part, the slide lock moves to the second part side and the engaging convex part engages with the engaging hole to perform locking. It is possible to adopt a configuration in which the fitting is released by moving the slide lock to the first part side from the state in which the convex part is fitted in the engaging hole.
上記した何れかの支持脚は、第１部の第１水平部から第２部の第２水平部側へ延びた連結部を更に備えた構成とすることが可能である。枢軸部は、連結部を第２部の第２水平部に軸支することによって、第２部を第１部に枢動可能に連結する構成とすることが可能である。 Any of the above-described support legs may further include a connecting portion extending from the first horizontal portion of the first portion toward the second horizontal portion of the second portion. The pivot part can be configured to pivotally connect the second part to the first part by pivotally supporting the connecting part on the second horizontal part of the second part.
枢軸部は、第２部の第２水平部における移行箇所の近傍に連結部を軸支した構成とすることが可能である。移行箇所は、第２水平部が第２起立部に移行する箇所とすることが可能である。 The pivot portion may be configured such that the connecting portion is pivotally supported in the vicinity of the transition portion in the second horizontal portion of the second portion. The transition location can be a location where the second horizontal portion transitions to the second upright portion.

（１）第２水平部３８がＺ−Ｚ’方向において第１水平部３２に重なる場合（図１〜図６参照）、各支持脚１６は連結部２６を有している。連結部２６は、第１水平部３２の先端部からＺ’方向側（第２水平部３８側）に延びており、連結部２６のＺ’方向側の端部はＺ’方向に開放された略Ｕ字状であって、その内部に第２水平部３８の移行箇所の近傍（移行箇所よりもＸ方向側の部分）が挿入されている。枢軸部２４は、連結部２６のＺ’方向側の端部及び第２水平部３８の移行箇所よりＸ方向側の部分をＹ−Ｙ’方向に貫通した軸であって、連結部２６を第２水平部３８に軸支している。このように枢軸部２４は、連結部２６を介して第２部２２を第１部２０に間接的に枢軸可能に連結している。 (1) When the second horizontal portion 38 overlaps the first horizontal portion 32 in the Z-Z ′ direction (see FIGS. 1 to 6), each support leg 16 has a connecting portion 26. The connecting portion 26 extends from the distal end portion of the first horizontal portion 32 to the Z ′ direction side (second horizontal portion 38 side), and the end portion on the Z ′ direction side of the connecting portion 26 is opened in the Z ′ direction. It is substantially U-shaped, and the vicinity of the transition location of the second horizontal portion 38 (the portion on the X direction side from the transition location) is inserted therein. The pivot portion 24 is an axis that penetrates the end portion on the Z ′ direction side of the connecting portion 26 and the portion on the X direction side from the transition position of the second horizontal portion 38 in the YY ′ direction. 2 is pivotally supported by the horizontal portion 38. As described above, the pivot portion 24 indirectly couples the second portion 22 to the first portion 20 via the coupling portion 26 so as to be pivotable.
なお、連結部２６のＺ’方向側の端部の内部には、第２水平部３８の移行箇所よりＸ方向側の部分以外の部分が挿入されており、枢軸部２４は、連結部２６のＺ’方向側の端部及び第２水平部３８の移行箇所よりＸ方向側の部分以外の部分をＹ−Ｙ’方向に貫通していても構わない。連結部２６は、第１水平部３２の先端部よりもＸ方向側の部分から延びていても構わない。 A portion other than the portion on the X direction side from the transition position of the second horizontal portion 38 is inserted into the end portion on the Z ′ direction side of the connecting portion 26, and the pivot portion 24 is connected to the connecting portion 26. A portion other than the portion on the X direction side from the end portion on the Z ′ direction side and the transition portion of the second horizontal portion 38 may be penetrated in the YY ′ direction. The connecting portion 26 may extend from a portion closer to the X direction than the distal end portion of the first horizontal portion 32.
（２）第２水平部３８がＹ−Ｙ’方向において第１水平部３２に重なる場合（図示せず）、各支持脚１６は連結部２６の代わりに図示しないスペーサを有している。スペーサは、第１水平部３２の先端部と第２水平部３８の移行箇所よりＸ方向側の部分との間に介在しており、枢軸部２４は、スペーサ、第２水平部３８の先端部及び第１水平部３２の移行箇所よりＸ方向側の部分をＹ−Ｙ’方向に貫通した軸である。このように枢軸部２４は、スペーサを介して第２部２２を第１部２０に間接的に枢軸可能に連結している。 (2) When the second horizontal portion 38 overlaps the first horizontal portion 32 in the Y-Y ′ direction (not shown), each support leg 16 has a spacer (not shown) instead of the connecting portion 26. The spacer is interposed between the tip portion of the first horizontal portion 32 and the portion on the X direction side from the transition position of the second horizontal portion 38, and the pivot portion 24 is the tip portion of the spacer and the second horizontal portion 38. And an axis that penetrates the portion on the X direction side from the transition position of the first horizontal portion 32 in the YY ′ direction. As described above, the pivot portion 24 indirectly couples the second portion 22 to the first portion 20 via the spacer.
なお、スペーサは第１水平部３２の任意の部分と第２水平部３８の任意の部分との間に介在でき、枢軸部２４は、スペーサと第１水平部３２の任意の部分と第２水平部３８の任意の部分とをＹ−Ｙ’方向に貫通していても構わない。 The spacer can be interposed between an arbitrary portion of the first horizontal portion 32 and an arbitrary portion of the second horizontal portion 38, and the pivot portion 24 is connected to the spacer and an arbitrary portion of the first horizontal portion 32 with the second horizontal portion. An arbitrary portion of the portion 38 may be penetrated in the YY ′ direction.
また、枢軸部２４は、拡張位置と縮小位置との間で第２部２２を第１部２０に連結部２６又はスペーサを介さず直接的に枢軸可能に連結した構成とすることが可能である。例えば、この構成としては、下記（３）又は（４）の通りとすることが可能である。この場合、連結部２６及びスペーサは省略される。 Further, the pivot portion 24 can be configured such that the second portion 22 is connected to the first portion 20 directly between the expanded position and the contracted position without being connected to the connecting portion 26 or the spacer. . For example, this configuration can be as described in (3) or (4) below. In this case, the connecting part 26 and the spacer are omitted.
（３）第２水平部３８がＺ−Ｚ’方向において第１水平部３２に重なる場合、第１水平部３２の先端部がＸ’方向に開放された略Ｕ字状であって、その内部に第２起立部３６の移行箇所よりもＺ’方向側の部分又は移行箇所が挿入されている。枢軸部２４は、第１水平部３２の先端部及び第２起立部３６の移行箇所よりもＺ’方向側の部分又は移行箇所をＹ−Ｙ’方向に貫通した軸である。このように枢軸部２４は、第２部２２を第１部２０に直接的に枢軸可能に連結している。 (3) When the second horizontal portion 38 overlaps the first horizontal portion 32 in the ZZ ′ direction, the distal end portion of the first horizontal portion 32 has a substantially U shape opened in the X ′ direction, and the inside In addition, a portion or a transition portion on the Z ′ direction side of the transition portion of the second upright portion 36 is inserted. The pivot portion 24 is a shaft that penetrates in the Y-Y ′ direction through a portion or transition portion on the Z ′ direction side from the transition portion of the first horizontal portion 32 and the second standing portion 36. As described above, the pivot portion 24 connects the second portion 22 to the first portion 20 so as to be pivotable.
（４）上記（２）の構成において、スペーサを省略し、枢軸部２４が、第２水平部３８及び第１水平部３２をＹ−Ｙ’方向に貫通した構成とすることが可能である。このようにしても、枢軸部２４は、第２部２２を第１部２０に直接的に枢軸可能に連結している。 (4) In the configuration of (2), the spacer can be omitted, and the pivot portion 24 can be configured to penetrate the second horizontal portion 38 and the first horizontal portion 32 in the Y-Y ′ direction. Even in this case, the pivot portion 24 connects the second portion 22 to the first portion 20 directly so as to be pivotable.

The exposed portion of the first longitudinal support pole 18 is fitted into the first fastener 60 from the X direction side. The second fastener 60 is a substantially C-shaped hook opposite to the first fastener 60 opened in the X ′ direction. The exposed portion of the second longitudinal support pole 18 is fitted into the second fastener 60 from the X ′ direction side. In the expanded state, the distance in the XX ′ direction from the first fastener 60 to the second fastener 60 is the first distance D1 (see FIG. 5), whereby the first longitudinal support pole 18 and the second The distance from the longitudinal support pole 18 opens approximately the same as or slightly larger than the size of the bed portion 12 in the XX ′ direction, and the bed portion 12 is tensioned in the XX ′ direction. On the other hand, in the reduced state, the distance in the XX ′ direction from the first fastener 60 to the second fastener 60 becomes the second distance D2 (see FIG. 4), and thereby the first longitudinal support pole 18 and the first fastener The distance between the two longitudinal support poles 18 becomes smaller than the dimension of the bed portion 12 in the XX ′ direction, and the tension of the bed portion 12 is released. In this state, the exposed portion of the first longitudinal support pole 18 can be removed from the first fastener 60, and the exposed portion of the second longitudinal support pole 18 can be removed from the second fastener 60.
各支持脚１６は、スライドロック２８を更に有している。スライドロック２８は、第１部２０の第１水平部３２にスライド自在に設けられている（図４〜図６参照）。上記拡張状態で、スライドロック２８がＸ’方向側（第２部２２側）に移動して第２部２２の第２水平部３８をロックする一方で、スライドロック２８が第２水平部３８をロックした状態からスライドロック２８がＸ方向側（第１部２０側）に移動することにより前記ロックが解除される構成となっている。例えば、この構成としては、下記（５）又は（６）の通りとすることが可能である。 Each support leg 16 further has a slide lock 28. The slide lock 28 is slidably provided on the first horizontal portion 32 of the first portion 20 (see FIGS. 4 to 6). In the expanded state, the slide lock 28 moves to the X ′ direction side (second portion 22 side) to lock the second horizontal portion 38 of the second portion 22, while the slide lock 28 locks the second horizontal portion 38. The lock is released when the slide lock 28 moves from the locked state to the X direction side (the first part 20 side). For example, this configuration can be as described in (5) or (6) below.

以下、コット１０の組立手順について詳しく説明する。まず、寝床部１２及び第１、第２長手支持ポール１８を用意する。寝床部１２の第１、第２スリーブ１２１に第１、第２長手支持ポール１８を挿入する。すると、第１、第２長手支持ポール１８の露出部が第１、第２スリーブ１２１の切り欠き５０から露出する。 Hereinafter, the assembly procedure of the cot 10 will be described in detail. First, the bed portion 12 and the first and second longitudinal support poles 18 are prepared. The first and second longitudinal support poles 18 are inserted into the first and second sleeves 121 of the bed 12. Then, the exposed portions of the first and second longitudinal support poles 18 are exposed from the notches 50 of the first and second sleeves 121.
その後、複数の支持脚１６を用意する。各支持脚１６の第２部２２が第１部２０に対して縮小位置に位置させる。この状態で、各支持脚１６の第２部２２の第２水平部３８は、第１部２０の第１水平部３２に対して傾斜しており、各支持脚１６の第１部２０の第１留め具６０及び第２部２２の第２留め具６０は第２距離Ｄ２で位置している。このように各支持脚１６を縮小状態とする。この縮小状態を維持しつつ、第１部２０の第１留め具６０を第１スリーブ１２１の対応する切り欠き５０を通じて第１長手支持ポール１８の対応する露出部にアクセスさせ、第１長手支持ポール１８の露出部を第１部２０の第１留め具６０内に嵌合させることができると共に、第２部２２の第２留め具６０を第２スリーブ１２１の対応する切り欠き５０を通じて第２長手支持ポール１８の対応する露出部にアクセスさせ、第２長手支持ポール１８の露出部を第２部２２の第２留め具６０内に嵌合させることができる。 Thereafter, a plurality of support legs 16 are prepared. The second portion 22 of each support leg 16 is positioned at the contracted position with respect to the first portion 20. In this state, the second horizontal part 38 of the second part 22 of each support leg 16 is inclined with respect to the first horizontal part 32 of the first part 20, and the first part 20 of each support leg 16 has the first part 20. The first fastener 60 and the second fastener 60 of the second portion 22 are located at the second distance D2. In this way, each support leg 16 is in a reduced state. While maintaining this contracted state, the first fastener 60 of the first part 20 is accessed to the corresponding exposed part of the first longitudinal support pole 18 through the corresponding notch 50 of the first sleeve 121, and the first longitudinal support pole 18 exposed portions can be fitted into the first fastener 60 of the first portion 20, and the second fastener 60 of the second portion 22 can be inserted into the second longitudinal direction through the corresponding notch 50 of the second sleeve 121. The corresponding exposed portion of the support pole 18 can be accessed and the exposed portion of the second longitudinal support pole 18 can be fitted into the second fastener 60 of the second portion 22.
その後、各支持脚１６の第２部２２を第１部２０に対して縮小位置から拡張位置へ枢動させる。これにより、各支持脚１６の第２部２２の第２水平部３８と第１部２０の第１水平部３２とが略平行になり、且つ各支持脚１６の第１部２０の第１留め具６０及び第２部２２の第２留め具６０が第１距離Ｄ１で位置する。これにより、各支持脚１６が拡張状態となり、第１長手支持ポール１８と第２長手支持ポール１８との間の距離が離間し、寝床部１２が緊張状態で第１長手支持ポール１８と第２長手支持ポール１８とに懸架される。 Thereafter, the second portion 22 of each support leg 16 is pivoted with respect to the first portion 20 from the contracted position to the expanded position. Thus, the second horizontal portion 38 of the second portion 22 of each support leg 16 and the first horizontal portion 32 of the first portion 20 are substantially parallel, and the first fastening of the first portion 20 of each support leg 16 is achieved. The tool 60 and the second fastener 60 of the second part 22 are located at the first distance D1. Thereby, each support leg 16 will be in an expanded state, the distance between the 1st longitudinal support pole 18 and the 2nd longitudinal support pole 18 will space apart, and the bed part 12 will be in a tension | tensile_strength, and the 1st longitudinal support pole 18 and 2nd Suspended from the longitudinal support pole 18.
その後、各支持脚１６のスライドロック２８をＸ’方向側（第２部２２側）に移動させてスライドロック２８に第２部２２の第２水平部３８を上記した何れかの態様でロックさせる。これにより、各支持脚１６が拡張状態で維持される。以上のようにコット１０が組み立てられる。 Thereafter, the slide lock 28 of each support leg 16 is moved to the X ′ direction side (second portion 22 side), and the second horizontal portion 38 of the second portion 22 is locked to the slide lock 28 in any of the above-described manners. . Thereby, each support leg 16 is maintained in an expanded state. The cot 10 is assembled as described above.
以下、コット１０の分解手順について詳しく説明する。各支持脚１６のスライドロック２８をＸ方向側（第１部２０側）に移動させてスライドロック２８と第２部２２の第２水平部３８との上記した何れかの態様のロックを解除させる。 Hereinafter, a procedure for disassembling the cot 10 will be described in detail. The slide lock 28 of each support leg 16 is moved to the X direction side (first part 20 side) to release the lock in any of the above-described manner between the slide lock 28 and the second horizontal part 38 of the second part 22. .
その後、各支持脚１６の第２部２２を第１部２０に対して拡張位置から縮小位置へ枢動させる。これにより、各支持脚１６の第２部２２の第２水平部３８が第１部２０の第１水平部３２に対して傾斜し、且つ各支持脚１６の第１部２０の第１留め具６０及び第２部２２の第２留め具６０が第２距離Ｄ２で位置する。これにより、各支持脚１６が縮小状態となり、第１長手支持ポール１８と第２長手支持ポール１８との間の距離が接近し、寝床部１２の緊張が解除される。その後、第１部２０の第１留め具６０と第１長手支持ポール１８の対応する露出部との嵌合及び第２部２２の第２留め具６０と第２長手支持ポール１８の露出部との嵌合を解除させる。 Thereafter, the second portion 22 of each support leg 16 is pivoted with respect to the first portion 20 from the expanded position to the contracted position. As a result, the second horizontal portion 38 of the second portion 22 of each support leg 16 is inclined with respect to the first horizontal portion 32 of the first portion 20, and the first fastener of the first portion 20 of each support leg 16. 60 and the second fastener 60 of the second part 22 are located at a second distance D2. Thereby, each support leg 16 will be in a contracted state, the distance between the 1st longitudinal support pole 18 and the 2nd longitudinal support pole 18 will approach, and the tension | tensile_strength of the bed part 12 will be cancelled | released. Thereafter, the fitting of the first fastener 60 of the first part 20 and the corresponding exposed part of the first longitudinal support pole 18 and the exposed part of the second fastener 60 of the second part 22 and the second longitudinal support pole 18 Release the fitting.
その後、寝床部１２の第１、第２スリーブ１２１から第１、第２長手支持ポール１８を引き抜く。以上の通りコット１０が分解される。 Thereafter, the first and second longitudinal support poles 18 are pulled out from the first and second sleeves 121 of the bed 12. As described above, the cot 10 is disassembled.
以上のようなコット１０及び支持脚１６による場合、各支持脚１６において、スライドロック２８が第１水平部３２にスライド自在に設けられおり、このスライドロック２８が、第２部２２が第１部２０に対して拡張位置に位置する状態で第２部２２側に移動して第２水平部３８をロックしているため、仮に第１部２０及び／又は第２部２２に外力が加わったとしても、スライドロック２８のロックが外れ難いため、第２部２２が第１部２０に対して拡張位置から縮小位置に枢軸する可能性が低減される。 In the case of the cot 10 and the support leg 16 as described above, the slide lock 28 is slidably provided on the first horizontal portion 32 in each support leg 16, and the second portion 22 is the first portion of the slide lock 28. Since the second horizontal portion 38 is locked by moving to the second portion 22 side in a state of being in the extended position with respect to 20, it is assumed that an external force is applied to the first portion 20 and / or the second portion 22 However, since the slide lock 28 is difficult to unlock, the possibility that the second portion 22 pivots from the extended position to the reduced position with respect to the first portion 20 is reduced.

In the first part of the rib member, the connecting part 26 and the pivot part 24 may be adjacent to the tip of the horizontal part 32 of the first part of the rib member.
The pivoting allows the first part of the rib member to pivot between the reduced position and the expanded position relative to the second part of the rib member. The contraction position is inclined so that the horizontal portion of the second part is separated from the horizontal portion of the first part, and the tip of the rising part of the first part is the first distance with respect to the tip of the rising part of the second part. It is a position in. In the extended position, the horizontal part of the first part is parallel to and adjacent to the horizontal part of the second part, and the tip of the standing part of the first part is the first part of the standing part of the second part. The second distance is greater than the first distance.
The skeleton also includes first and second longitudinal support members 18. The 1st, 2nd longitudinal support member is engaged with the front-end | tip of the standing part of each rib member so that removal is possible. When the cot is set up in the normal form in which each rib member is in the extended position, the respective leading ends of the first and second raised portions of the rib member separate the longitudinal support members. When the cot is set up in a contracted configuration in which the rib member is in the contracted position, the leading ends of the first and second raised portions of the rib member are smaller than the expanded position, and the longitudinal support member is separated. The flexible support member may have a sleeve into which the longitudinal support member is inserted at both ends thereof. A plurality of notches 50 may be provided at both ends of the flexible support member, and the longitudinal support member can be accessed through the notches.
The leading end of each rib member may have a fastener 60. The front end of the upright portion may be detachably engageable with the longitudinal support member by the fastener. The fasteners may be inserted into the notches of the flexible member so that the tips of the standing portions of the rib members can be removably engaged with the corresponding longitudinal support members. The fastener may be sized to engage the longitudinal support member. The longitudinal support member may have a round cross section or a pole. The fastener may have a C-shaped cross section, and a pole can be inserted into the inner diameter portion of the C-shaped fastener.
A fastener may be provided at the leading end of the rising portion of the first part of the rib member, and the longitudinal support member on the opposite side has the same configuration at the leading end of the standing part of the second part of the rib member. A fastener may be provided that engages the.
In preparing the cot, the flexible member may be disposed in the longitudinal direction with respect to the framework. Longitudinal support poles may be inserted into sleeves at both ends of the flexible support member. You may arrange | position a some rib member at intervals in a longitudinal direction in the general area | region for engaging with a longitudinal support member. The standing part of the first part of the rib member may be inserted into the notch of the flexible member so that the fastener is engaged with the longitudinal support pole within the notch. This process may be repeated along the length of the cot for each rib member.
Then, with the rib member in the contracted position, the leading end of the second portion of the rib member is inserted into the notch of the flexible member, and the fastener is engaged with the longitudinal support pole within the notch. You may do it. This process may be repeated along the length of the cot for each rib member.
Then, the rib member may be positioned at the extended position by pivoting the second part of the rib member with respect to the first part. As a result, the fasteners on the tips of the first and second parts are moved away from each other, and the longitudinal support members are moved away from each other in the sleeves at both ends of the flexible support member. Sexual members are tightly stretched. The second part of the rib member pivots relative to the first part of the rib member, so that the horizontal part of the second part of the rib member is adjacent to the horizontal part of the first part of the rib member. With the horizontal portions of the first and second portions of each rib member being adjacent to each other, the rib members are collectively locked and the flexible member is tightly pulled outward by sliding the fastener to a predetermined position. Subsequently, the cot may be supported by this. Even if some force is applied to the surface of the flexible member so that the fasteners on the tips of the first and second raised portions of the rib members can be moved closer to each other, the fasteners are placed on the ground. The placed rib member can counter the force. To fold the cot for storage, the reverse procedure may be performed.
