The second step portion 67 is formed around the second recess 66 and defines the outer edge of the second recess 66. The second step portion 67 can regulate the movement of the second tip portion 22 of the first engaging portion 15 located inside the second recess 66 in the lateral direction and the downward direction.

第２溝部６８は、第２凹部６６と一体的に形成され、第２凹部６６から上方向に延びるように形成されている。第２溝部６８は、第２凹部６６と同一の深さで周囲よりも窪んでいる。第２溝部６８の幅は、第２凹部６６の直径と同じに形成され、第２先端部２２（軸部２１Ａ）の直径よりも若干大きい寸法で形成されている。このため、第２溝部６８の内側を第１係合部１５の第２先端部２２が移動することができる。したがって、第２溝部６８は、第２凹部６６の内側に保持された第１係合部１５の第２先端部２２が上方に移動（相対移動）することを許容することができる。 The second groove portion 68 is integrally formed with the second recess 66, and is formed so as to extend upward from the second recess 66. The second groove portion 68 is recessed from the periphery at the same depth as the second recess 66. The width of the second groove portion 68 is formed to be the same as the diameter of the second recess 66, and is formed to have a size slightly larger than the diameter of the second tip portion 22 (shaft portion 21A). Therefore, the second tip portion 22 of the first engaging portion 15 can move inside the second groove portion 68. Therefore, the second groove portion 68 can allow the second tip portion 22 of the first engaging portion 15 held inside the second recess 66 to move upward (relatively move).

図１、図２、図１２〜図１８を参照して、格納ベッド１１の引き出し動作および格納動作について説明する。 The drawer operation and the storage operation of the storage bed 11 will be described with reference to FIGS. 1, 2, and 12 to 18.

図２に示す起立状態の第１位置Ｐ１から図１に示す横置き状態（使用状態）の第２位置Ｐ２にする引き出し動作について説明する。 The pulling-out operation from the first position P1 in the upright state shown in FIG. 2 to the second position P2 in the horizontal state (used state) shown in FIG. 1 will be described.

ユーザは、フレーム２３に設けられた図示しない安全ロックを解除して、ベッド本体１３を回動可能な状態にする。ユーザは、図１２に示すように、ベッド本体１３側に設けられた操作用ロッド１７を下方に引っ張って、ベッド本体１３を第１位置Ｐ１から第２位置Ｐ２に回動させる。そして、ユーザは、支持部１２のフレーム２３に設けられたロックレバー２５を操作して、第２位置Ｐ２においてベッド本体１３を固定する。 The user releases a safety lock (not shown) provided on the frame 23 to make the bed body 13 rotatable. As shown in FIG. 12, the user pulls the operation rod 17 provided on the bed body 13 side downward to rotate the bed body 13 from the first position P1 to the second position P2. Then, the user operates the lock lever 25 provided on the frame 23 of the support portion 12 to fix the bed body 13 at the second position P2.

第２位置Ｐ２にしたベッド本体１３の柵部材３３に対して、ユーザは、図１３に示すように、梯子部１４のフック４４を引っ掛けるようにする。ユーザは、この柵部材３３・フック４４を支点に、図１４に示すように梯子部１４を回動させ、第２係合部１６の左部材５１と右部材５２との間に第１係合部１５を位置させる。これによって、第１係合部１５の第１先端部２１が第２係合部１６の左部材５１の第１滑面５６に当接し、第１係合部１５の第２先端部２２が第２係合部１６の右部材５２の第２滑面６５に当接する。これによって、第１先端部２１がロッド部４５の内部に押し込まれ、第２先端部２２がロッド部４５の内部に押し込まれる。また、第２係合部１６に対して第１係合部１５の位置がずれている場合には、第１滑面５６および第２滑面６５に第１係合部１５のロッド部４５が当接し、梯子部１４が微小距離だけ移動されることで、梯子部１４の左右方向の位置が微調整される。ユーザが柵部材３３・フック４４を支点とする梯子部１４の回動をそのまま継続すると、図１５、図１６に示すように、第１凹部５７の内側に第１係合部１５の第１先端部２１が落ち込み、第２凹部６６の内側に第１係合部１５の第２先端部２２が落ち込む。これによって、第１係合部１５に対して第２係合部１６が係合した状態となる。これによって、ベッド本体１３が第２位置Ｐ２にするときに、梯子部１４がベッド本体１３から外れないようになる。ユーザは、この状態で、寝具等をベッド本体１３に載置することで、ベッドを使用することができる。本実施形態の格納ベッド１１は、通常の使用状態では、ベッド本体１３から梯子部１４が外れることはない。すなわち、梯子部１４は、ベッド本体１３を上方に持ち上げない限り、ベッド本体１３から外れることがなく、ユーザの安全が確保される。 As shown in FIG. 13, the user hooks the hook 44 of the ladder portion 14 to the fence member 33 of the bed body 13 at the second position P2. The user rotates the ladder portion 14 with the fence member 33 / hook 44 as a fulcrum as shown in FIG. 14, and first engages the second engaging portion 16 between the left member 51 and the right member 52. Position the unit 15. As a result, the first tip portion 21 of the first engaging portion 15 comes into contact with the first sliding surface 56 of the left member 51 of the second engaging portion 16, and the second tip portion 22 of the first engaging portion 15 is second. 2 The engagement portion 16 comes into contact with the second sliding surface 65 of the right member 52. As a result, the first tip portion 21 is pushed into the rod portion 45, and the second tip portion 22 is pushed into the inside of the rod portion 45. Further, when the position of the first engaging portion 15 is displaced with respect to the second engaging portion 16, the rod portion 45 of the first engaging portion 15 is placed on the first sliding surface 56 and the second sliding surface 65. The position of the ladder portion 14 in the left-right direction is finely adjusted by abutting the ladder portion 14 and moving the ladder portion 14 by a minute distance. When the user continues to rotate the ladder portion 14 with the fence member 33 and the hook 44 as fulcrums, as shown in FIGS. 15 and 16, the first tip of the first engaging portion 15 is inside the first recess 57. The portion 21 is depressed, and the second tip portion 22 of the first engaging portion 15 is depressed inside the second recess 66. As a result, the second engaging portion 16 is engaged with the first engaging portion 15. As a result, the ladder portion 14 does not come off from the bed main body 13 when the bed main body 13 is set to the second position P2. In this state, the user can use the bed by placing the bedding or the like on the bed body 13. In the storage bed 11 of the present embodiment, the ladder portion 14 does not come off from the bed body 13 under normal use conditions. That is, the ladder portion 14 does not come off from the bed main body 13 unless the bed main body 13 is lifted upward, and the safety of the user is ensured.

ユーザがベッド本体１３を格納したい場合には、ベッド本体１３から寝具等を降ろす。ユーザは、ロックレバー２５を解除して、ベッド本体１３が第２位置Ｐ２から第１位置Ｐ１に回動できる状態にする。図１７、図１８に示すように、ユーザは、一方の手でベッド本体１３を第２位置Ｐ２から第１位置Ｐ１に回動するように持ち上げる。これによって、第１係合部１５の第１先端部２１が第２係合部１６の第１溝部６１を通って上方向に移動し、第１係合部１５の第２先端部２２が第２係合部１６の第２溝部６８を通って上方向に移動する。これによって、第１係合部１５と第２係合部１６の係合状態が解除される。このため、ユーザは、図１８に示すように、他方の手で梯子部１４をベッド本体１３から引き離すことができる。 When the user wants to store the bed body 13, bedding or the like is removed from the bed body 13. The user releases the lock lever 25 so that the bed body 13 can rotate from the second position P2 to the first position P1. As shown in FIGS. 17 and 18, the user lifts the bed body 13 with one hand so as to rotate from the second position P2 to the first position P1. As a result, the first tip portion 21 of the first engaging portion 15 moves upward through the first groove portion 61 of the second engaging portion 16, and the second tip portion 22 of the first engaging portion 15 is second. 2 It moves upward through the second groove portion 68 of the engaging portion 16. As a result, the engaged state of the first engaging portion 15 and the second engaging portion 16 is released. Therefore, as shown in FIG. 18, the user can pull the ladder portion 14 away from the bed body 13 with the other hand.

ユーザがそのままベッド本体１３を上方向に回動させ、図示しない安全ロックをすることで、ベッド本体１３を第１位置Ｐ１に固定することができる。 The bed body 13 can be fixed to the first position P1 by the user rotating the bed body 13 upward as it is and locking the bed body 13 (not shown).

第１実施形態によれば、以下のことがいえる。格納ベッド１１は、支持部１２と、縦方向に起立した第１位置Ｐ１と、横方向に延びた第２位置Ｐ２と、の間で回動可能に支持部１２に支持されたベッド本体１３と、第２位置Ｐ２にあるベッド本体１３に対して着脱可能な梯子部１４と、ベッド本体１３に設けられロッド状をなすとともに第１先端部２１を有する第１係合部１５と、梯子部１４に設けられ第１先端部２１と係合可能な第２係合部１６と、を備え、第２係合部１６は、第１先端部２１と当接して第１先端部２１の横方向への移動を許容する第１滑面５６と、第１滑面５６に隣接して設けられ第１先端部２１が落ち込むとともに、落ち込んだ第１先端部２１が前記横方向に移動することを規制する第１凹部５７と、第１凹部５７から上方向に延びる第１溝部６１であって、第１凹部５７内に位置する第１先端部２１の上方向への移動を許容する第１溝部６１と、を有する。 According to the first embodiment, the following can be said.

The second step portion 67 can regulate the movement of the second tip portion 22 of the fourth engaging portion 72 located inside the second recess 66 in the lateral direction and the upward direction.

第２溝部６８は、第２凹部６６と一体的に形成され、第２凹部６６から下方向に延びるように形成されている。第２溝部６８は、第２凹部６６と同一の深さで周囲よりも窪んでいる。第２溝部６８の幅は、第２凹部６６の直径と同じに形成され、第２先端部２２（軸部２１Ａ）の直径よりも若干大きい寸法で形成されている。このため、第２溝部６８の内側を第１係合部１５の第２先端部２２が移動することができる。したがって、第２溝部６８は、第２凹部６６の内側に保持された第４係合部７２の第２先端部２２が下方に移動（相対移動）することを許容することができる。 The second groove portion 68 is integrally formed with the second recess 66, and is formed so as to extend downward from the second recess 66. The second groove portion 68 is recessed from the periphery at the same depth as the second recess 66. The width of the second groove portion 68 is formed to be the same as the diameter of the second recess 66, and is formed to have a size slightly larger than the diameter of the second tip portion 22 (shaft portion 21A). Therefore, the second tip portion 22 of the first engaging portion 15 can move inside the second groove portion 68. Therefore, the second groove portion 68 can allow the second tip portion 22 of the fourth engaging portion 72 held inside the second recess 66 to move downward (relative movement).

図１、図２、図１９〜図２２を参照して、格納ベッド１１の引き出し動作および格納動作について説明する。 The drawer operation and the storage operation of the storage bed 11 will be described with reference to FIGS. 1, 2, and 19 to 22.

図２に示す起立状態の第１位置Ｐ１から図１に示す横置き状態（使用状態）の第２位置Ｐ２にする引き出し動作について説明する。 The pulling-out operation from the first position P1 in the upright state shown in FIG. 2 to the second position P2 in the horizontal state (used state) shown in FIG. 1 will be described.

ユーザは、フレーム２３に設けられた図示しない安全ロックを解除して、ベッド本体１３を回動可能な状態にする。ユーザは、ベッド本体１３に手をかけて、ベッド本体１３を第１位置Ｐ１から第２位置Ｐ２に回動させる。そして、ユーザは、支持部１２のフレーム２３に設けられたロックレバー２５を操作して、第２位置Ｐ２においてベッド本体１３を固定する。 The user releases a safety lock (not shown) provided on the frame 23 to make the bed body 13 rotatable. The user puts his / her hand on the bed body 13 and rotates the bed body 13 from the first position P1 to the second position P2. Then, the user operates the lock lever 25 provided on the frame 23 of the support portion 12 to fix the bed body 13 at the second position P2.

第２位置Ｐ２にしたベッド本体１３の柵部材３３に対して、ユーザは、梯子部１４のフック４４を引っ掛けるようにする。ユーザは、この柵部材３３・フック４４を支点に、梯子部１４を回動させ、第２係合部１６の左部材５１と右部材５２との間に第１係合部１５を位置させる。これによって、第４係合部７２の第１先端部２１が第３係合部７１の左部材５１の第１滑面５６に当接し、第４係合部７２の第２先端部２２が第３係合部７１の右部材５２の第２滑面６５に当接する。これによって、第１先端部２１がロッド部４５の内部に押し込まれ、第２先端部２２がロッド部４５の内部に押し込まれる。また、第３係合部７１に対して第４係合部７２の位置がずれている場合には、第１滑面５６および第２滑面６５に第４係合部７２のロッド部４５が当接し、梯子部１４の左右方向の位置が微調整される。ユーザが柵部材３３・フック４４を支点とする梯子部１４の回動をそのまま継続すると、第１凹部５７の内側に第４係合部７２の第１先端部２１が落ち込み、第２凹部６６の内側に第４係合部７２の第２先端部２２が落ち込む。これによって、第３係合部７１に対して第４係合部７２が係合した状態となる。これによって、ベッド本体１３が第２位置Ｐ２にするときに、梯子部１４がベッド本体１３から外れないようになる。ユーザは、この状態で、寝具等をベッド本体１３に載置することで、ベッドを使用することができる。 The user hooks the hook 44 of the ladder portion 14 to the fence member 33 of the bed body 13 at the second position P2. The user rotates the ladder portion 14 with the fence member 33 / hook 44 as a fulcrum, and positions the first engaging portion 15 between the left member 51 and the right member 52 of the second engaging portion 16. As a result, the first tip portion 21 of the fourth engaging portion 72 comes into contact with the first sliding surface 56 of the left member 51 of the third engaging portion 71, and the second tip portion 22 of the fourth engaging portion 72 becomes the second. 3 The engagement portion 71 abuts on the second sliding surface 65 of the right member 52. As a result, the first tip portion 21 is pushed into the rod portion 45, and the second tip portion 22 is pushed into the inside of the rod portion 45. Further, when the position of the fourth engaging portion 72 is displaced with respect to the third engaging portion 71, the rod portion 45 of the fourth engaging portion 72 is placed on the first sliding surface 56 and the second sliding surface 65. The contact is made, and the position of the ladder portion 14 in the left-right direction is finely adjusted. When the user continues to rotate the ladder portion 14 with the fence member 33 and the hook 44 as fulcrums, the first tip portion 21 of the fourth engaging portion 72 falls inside the first recess 57, and the second recess 66 The second tip portion 22 of the fourth engaging portion 72 falls inward. As a result, the fourth engaging portion 72 is engaged with the third engaging portion 71. As a result, the ladder portion 14 does not come off from the bed main body 13 when the bed main body 13 is set to the second position P2. In this state, the user can use the bed by placing the bedding or the like on the bed body 13.

ユーザがベッド本体１３を格納したい場合には、ベッド本体１３から寝具等を降ろす。ユーザは、ロックレバー２５を解除して、ベッド本体１３が第２位置Ｐ２から第１位置Ｐ１に回動できる状態にする。ユーザは、一方の手でベッド本体１３を第２位置Ｐ２から第１位置Ｐ１に回動するように持ち上げる。これによって、第４係合部７２の第１先端部２１が第３係合部７１の第１溝部６１を通って下方向に相対移動（実際には第３係合部７１が上方に移動）し、第４係合部７２の第２先端部２２が第３係合部７１の第２溝部６８を通って下方向に相対移動（実際には第３係合部７１が上方に移動）する。これによって、第３係合部７１と第４係合部７２の係合状態が解除される。このため、ユーザは、他方の手で梯子部１４を手前に引くことでベッド本体１３から引き離すことができる。 When the user wants to store the bed body 13, bedding or the like is removed from the bed body 13. The user releases the lock lever 25 so that the bed body 13 can rotate from the second position P2 to the first position P1. The user lifts the bed body 13 with one hand so as to rotate from the second position P2 to the first position P1. As a result, the first tip portion 21 of the fourth engaging portion 72 moves downward relative to the first groove portion 61 of the third engaging portion 71 (actually, the third engaging portion 71 moves upward). Then, the second tip portion 22 of the fourth engaging portion 72 moves downward relative to the second groove portion 68 of the third engaging portion 71 (actually, the third engaging portion 71 moves upward). .. As a result, the engaged state of the third engaging portion 71 and the fourth engaging portion 72 is released. Therefore, the user can pull the ladder portion 14 toward the bed with the other hand to separate it from the bed body 13.

ユーザがそのままベッド本体１３を上方向に回動させ、図示しない安全ロックをすることで、ベッド本体１３を第１位置Ｐ１に固定することができる。 The bed body 13 can be fixed to the first position P1 by the user rotating the bed body 13 upward as it is and locking the bed body 13 (not shown).

第２実施形態によれば、以下のことがいえる。格納ベッド１１は、支持部１２と、縦方向に起立した第１位置Ｐ１と、横方向に延びた第２位置Ｐ２と、の間で回動可能に支持部１２に支持されたベッド本体１３と、第２位置Ｐ２にあるベッド本体１３に対して着脱可能な梯子部１４と、ベッド本体１３に設けられた第３係合部７１と、梯子部１４に設けられロッド状をなすとともに第３係合部７１と係合可能な第１先端部２１を有する第４係合部７２と、を備え、第３係合部７１は、第４係合部７２の第１先端部２１と当接して第１先端部２１の横方向への移動を許容する第１滑面５６と、第１滑面５６に隣接して設けられ第１先端部２１が落ち込むとともに、落ち込んだ第１先端部２１が前記横方向に移動することを規制する第１凹部５７と、第１凹部５７から下方向に延びる第１溝部６１であって、第１凹部５７内に位置する第１先端部２１の下方向への移動を許容する第１溝部６１と、を有する。 According to the second embodiment, the following can be said.
