  FIG. 1 shows a plan view of a storage type flip-up bed apparatus having a storage function inside the bed apparatus. FIG. 2 shows a cross section near the side board 10 of the bed apparatus. The height direction is shown as HW. FIG. 3 shows a cross-sectional view of the longitudinal reinforcing molded product 12, which is a main part of the side board 10, cut along the longitudinal direction. 4 to 6 show cross sections in a direction crossing the bed apparatus (the phantom line PK indicates the center line of the bed apparatus). The bed apparatus includes a bed main body 1 serving as a base and a floor plate 3 having an upper surface 31 as a mounting surface on which a mattress functioning as a bedding for a user to sleep is placed.

  As shown in FIG. 1, the bed main body 1 is arranged on two side boards 10 arranged along the length direction of the bed main body 1 sleeping in the bed apparatus, and on both ends in the length direction of the bed main body 1. End board 15 is provided. The end board 15 includes a head board 16 located on the user's head side and a foot board 17 located on the user's leg side and facing the head board 16. The foot board 17 has a sub board 17a inside. The bed main body 1 includes a space-shaped article storage chamber 2 having an article entrance 20 opened on the upper surface. The width of the article storage chamber 2 is shown as LB and LC (see FIG. 1). The height of the article storage chamber 2 is indicated as H1 (see FIG. 2). The base material of the head board 16 and the foot board 17 is not particularly limited, and may be wood, metal, or hard resin.

  As shown in FIG. 2, the side board 10 of the bed body 1 holds the floor board 3 and holds the floor board 3 and functions as a floor board mounting body extending along the length direction of the bed body 1. And a decorative member 14 that enhances the design of the plate shape joined to the outer surface of the longitudinal reinforcing molded product 12 by a fixing means such as an adhesive or screwing. The decorative member 14 is made of wood or resin. In some cases, the decorative member 14 may be abolished when a design is applied to the outer surface of the longitudinal reinforcing molded product 12. The longitudinal reinforcing molded product 12 is made of a metal material such as an aluminum alloy, an iron alloy, a titanium alloy, or a magnesium alloy along the height direction (the length direction of the bed device) of the user (the user who goes to bed). It is formed by continuous extrusion or pultrusion so as to have a predetermined cross-sectional shape by an extrusion die or a drawing die. As shown in FIG. 2, the longitudinal reinforcing molded product 12 includes a main mounting portion 122 having a hollow chamber 121 as a concave portion, a vertical column portion 124 connected to the main mounting portion 122, and a lower end portion of the vertical column portion 124. And a sub-mounting portion 126 having a plate shape connected to the. The sub placement portion 126 is disposed below the main placement portion 122 and in parallel with the main placement portion 122. The vertical column portion 124 has an upper end surface 124c and a lower end surface 124d. Since the longitudinal reinforcing molded article 12 has the hollow chamber 121 extending continuously along the length direction, the weight can be reduced while increasing the bending rigidity. The longitudinal reinforcement molded product 12 basically has the same cross-sectional shape along the length direction unless it is post-processed. The hollow chamber 121 has a quadrangular cross section, but is not limited thereto, and may be an ellipse or a circle in cross section. As shown in FIG. 2, the floor board 3 has a flat plate shape held by the bed body 1.

As shown in FIG. 1 (plan view), when the floor board 3 closes the article entrance / exit 20 of the article storage chamber 2, there is a gap 4 between the outer edge 3 k of the floor board 3 and the inner edge 1 i of the bed body 1. Is formed. When the floor board 3 is closed, the gap 4 is formed so as to make one round of the entire circumference of the floor board 3. That is, as shown in FIG. 1, the outer edge 3 k of the long side portion 35 of the floor board 3 is located inward of the inner edge 1 i of the side board 10 of the bed body 1. Further, the outer edge 3 k of the short side portion 36 of the floor board 3 is located inward of the inner edge 1 i of the end board 15 of the bed body 1. As a result, a gap 4 is formed between the outer edge 3 k of the floor board 3 and the inner edge 1 i of the bed body 1. That is, as shown in FIG. 1, a straight long side gap 4a having a gap width t1 is formed between the outer edge 3k of the long side portion 35 of the floor board 3 and the inner edge 1i of the side board 10 of the bed body 1. ing. Further, a straight short-side gap 4 c having a gap width t 2 is formed between the outer edge 3 k of the short side portion 36 of the floor board 3 and the inner edge 1 i of the end board 15 of the bed body 1. The gap width t1 and the gap width t2 are set so that the gap width t1 and t2 of the gap 4 are so narrow that a human finger cannot be inserted (for example, 8 mm or less, 5 mm or less), or The gap width is set to be considerably wider than the thickness (for example, 25 mm or more, 30 mm or more). For this reason, when the floor board 3 is opened and closed, a human finger or the like is prevented from being caught between the outer edge 3k of the floor board 3 and the inner edge 1i of the bed apparatus. The base material of the floor board 3 may be wood, metal, or hard resin. The floor board 3 is provided on the bed body 1 so as to be able to jump up. That is, one end side (head board 16 side) in the length direction of the floor board 3 is set as a swing center region 3c with a small or no swing amount. In addition, the other end portion (footboard 17 side) in the length direction of the floor board 3 is a swing end 3h (end portion) having a swing amount larger than the swing center region 3c. In this way, the swinging end 3h of the floor plate 3 is lifted up so as to be swingable, or is moved up or down. As the floor board 3 is flipped up, the article entrance / exit 20 of the article storage chamber 2 is opened, so that the article can be stored in the article storage chamber 2 from the article entrance / exit 20. As the floor board 3 is lowered, the article entrance / exit 20 of the article storage chamber 2 is closed by the floor board 3.

  The longitudinal reinforcement molded product 12 described above is a metal extrusion molded product or a pultruded molded product, has high bending rigidity and high strength, and extends along the length direction of the side board 10 of the bed apparatus. . Therefore, the bending rigidity and strength of the side board 10 of the bed apparatus are enhanced. Therefore, it is not necessary to provide the reinforcing bridge beam in the intermediate position in the length direction of the bed apparatus in the article storage chamber 2. Therefore, the length of the space-shaped article storage chamber 2 is indicated as LA (see FIG. 1), and is set to be long so as to substantially correspond to the length of the bed apparatus. The width of the article storage chamber 2 is shown as LB (see FIG. 1) at the longest portion, and the width of the article storage chamber 2 is shown as LC (see FIG. 1) at the shortest portion, which substantially corresponds to the width dimension of the bed apparatus. As a result, an article having a long length such as a ski can be stored in the article storage chamber 2. Moreover, there is an advantage that a plurality of articles having a long length such as skis can be stored in the article storage chamber 2 in a state where a plurality of articles are arranged side by side. As shown in FIG. 1, a partition wall 10 p and a partition wall 10 v are arranged in the article storage chamber 2 of the bed body 1 so as to face the article storage chamber 2. The partition 10p is extended along the length direction of the bed apparatus. The partition wall 10v is continuous with the partition wall 10p and extends along the width direction of the bed apparatus. The partition 10p and the partition 10v prevent the articles stored in the article storage chamber 2 from interfering with or coming into contact with the floor board drop suppressing mechanism 5. In this case, it is advantageous for avoiding damage to the floor board drop suppressing mechanism 5 and the article.

As a result, the floor board 3 can be placed in a horizontal state and the article entrance / exit 20 of the article storage chamber 2 can be closed. The lower handle 38D makes it easy to lower the floor plate 3. The lower handle 38D can function as a manual operation unit for lowering to manually lower the swinging end 3h of the floor plate 3 that has been flipped up. As described above, when the floor plate 3 is moved up and down in this way, in the first damper cylinder 55, the fluid (for example, gas or oil) is caused to flow through the first throttle passage 568 while generating flow resistance. It goes back and forth between the first forward chamber 565 and the first backward chamber 567. For this reason, the sudden fall of the floor board 3 that has jumped up in the direction of the arrow Y1 is suppressed, and safety is improved. Similarly, in the second damper cylinder 65, the fluid flows through the second throttle passage 668 and flows through the second forward passage chamber 665 and the second return passage chamber 667, so that the floor plate 3 is suddenly opened and closed. Is suppressed and safety is enhanced.

  FIG. 12 shows a comparative example. As shown in FIG. 12, when the floor board 3X closes the article entrance / exit 20X of the article storage chamber 2X, the outer edge 300X of the floor board 3X protrudes outward from the outer edge 100X of the bed body 1X. Therefore, when the floor board 3X is flipped up in the direction of the arrow Y1 in order to put in or out the article in the article storage chamber 2X, or when the floor board 3X that is flipped up is lowered, the outer edge 300X of the floor board 3X that is flipped up is There is a risk of contact with and rubbing against other objects in the vicinity (for example, adjacent bed devices, walls, etc. WX). In this case, the outer edge 300X of the floor board 3X may be rubbed and damaged. In particular, as shown in FIG. 12, when a plurality of bed devices having a floor plate 3X are arranged in a close-up state and installed in a twin type, when the floor plate 3X is flipped up, one storage type flip-up bed device is provided. There is a high risk that the outer edge 300X of the floor plate 3X will rub against the outer edge 300X of the floor plate 3X of the other storage type flip-up bed apparatus adjacent thereto. In this case, there is a risk of causing damage such as rubbing damage of the floor plate 3X to be flipped up.

  FIG. 11 shows a form in which a plurality of bed apparatuses according to the present embodiment are arranged close to each other. As shown in FIG. 11, when the floor board 3 closes the article entrance / exit 20 of the article storage chamber 2, the outer edge 3 k of the floor board 3 is located inward of the inner edge 1 i of the bed body 1. When the floor board 3 is closed, a gap 4 is formed between the outer edge 3k of the floor board 3 and the inner edge 1i of the bed body 1 so as to form a frame ring that goes around the entire circumference of the floor board 3. For this reason, even when the floor board 3 rises in the direction of the arrow Y1 or when the floor board 3 falls in the direction of the arrow Y2, the outer edge 3k of the floor board 3 of each bed apparatus can rub against the inner edge 1i of the bed body 1. It is prevented. Furthermore, the outer edge 3k of the floor board 3 is prevented from rubbing against other objects (for example, the wall WX). Therefore, rubbing damage of the outer edge 3k of the floor board 3 is prevented. In particular, as shown in FIG. 11, even when a plurality of bed apparatuses are arranged side by side in an approaching state, the bed apparatus is provided in an approaching state on a wall WX as another object. In addition, the floor plate 3 of the one bed apparatus that moves up and down is prevented from rubbing against the bed body 1 and the wall WX of the other bed apparatus. For this reason, an unreasonable load is prevented from acting on the floor board 3, the bed main body 1 that holds the floor board 3 so as to be movable up and down, and the floor board drop suppressing mechanism 5. Therefore, it is possible to contribute to avoiding damage to the floor board 3, the bed main body 1, and the floor board drop suppressing mechanism 5.

  As shown in FIG. 15, since the mattress MA can be elastically deformed, there is no problem even if the upper handle 38U exists below the end portion MA13 of the mattress MA. However, the end portion MA13 'of the mattress MA may be disposed at a position where the upper handle 38U does not interfere. The upper handle 38U may be folded so as to lie on the upper surface 31. As shown in FIG. 15, the locked body 7 is fixed to the bed body 1 on the footboard 17 side. The to-be-locked body 7 has a to-be-locked surface 71 along a horizontal plane and a guided surface 72 formed by an inclined surface that is inclined along the direction of gravity. A lock device 8 is provided on the floor plate 3 on the swing end 3h side. The lock device 8 locks the floor plate 3 to the bed body 1 in a state where the floor plate 3 closes the article entrance 20 of the article storage chamber 2 (see FIG. 15). The lock device 8 is attached to the swing end 3 h side of the floor plate 3. In particular, as shown in FIG. 1, in consideration of manual operability, the locking device 8 is positioned below the upper handle 38U on the swing end 3h side of the floor plate 3, and is positioned in the width direction of the floor plate 3 (in the direction of the arrow DE). ) Is attached in the middle area. As shown in FIG. 16, the locking device 8 includes a rotary release operator 80 arranged so as to face the window opening 38 t in a recess 380 formed in the floor plate 3, and a release operator 80. It has a lock body 82 that is unlocked by rotation, and a fixed base 87 that holds the lock body 82 so as to be able to advance and retreat. The distal end portion of the lock body 82 has a lock surface 83 along a horizontal plane and a guide surface 84 formed of an inclined surface inclined along the direction of gravity. As shown in FIG. 16, the release operation element 80 in the recess 380 and the upper handle 38U outside the recess 380 face each other through the window opening 38t. For this reason, when operating the upper handle 38U with fingers, there is an advantage that the operation status of the release operator 80 can be confirmed. Furthermore, continuous operability of the upper handle 38U and the release operator 80 is ensured.

  As shown in FIG. 17, the release operator 80 includes a pinion-shaped first tooth portion 81. The lock body 82 is slidably provided on the guide 82 m and has a rack-like second tooth portion 85 that can mesh with the first tooth portion 81. The lock body 82 is constantly urged in the lock direction (arrow E1 direction) by an urging spring 86 as an urging element. Thus, when the floor plate 3 closes the article entrance / exit 20 of the article storage chamber 2, as shown in FIG. 16, when the lock surface 83 of the lock body 82 and the locked surface 71 of the locked body 7 are engaged. The floor board 3 is locked so that it cannot be detached from the bed body 1. In a state where the floor plate 3 is locked so as not to be detached from the bed main body 1, a finger is inserted from the window opening 38t of the recess 380, and the user unlocks the release operation element 80 about its axis P1 (arrow). When the rotation operation is performed in the R2 direction, the first tooth portion 81 connected to the release operation element 80 is rotated in the unlocking direction (arrow R2 direction), and the lock body 82 is moved in the unlocking direction (arrow E2 direction). Retreat. As a result, the lock surface 83 at the tip of the lock body 82 is detached from the locked surface 71 of the lock body 7, so that the floor plate 3 is unlocked, and the floor plate 3 can be lifted, that is, opened.

  When the user's finger is released from the release operation element 80, the lock body 82 is automatically moved in the lock direction (arrow E1 direction) by the biasing force of the biasing spring 86. When the rising floor plate 3 is lowered, the guide surface 84 of the lock body 82 hits the guided surface 72 of the locked body 7 and elastically contracts the urging spring 86, while the lock body 82 is unlocked (arrow E2). Backward). For this reason, the lock surface 83 of the lock body 82 can get over the locked body 7. Thereafter, the lock body 82 automatically moves forward in the lock direction (arrow E1 direction) by the biasing force of the bias spring 86, so that the lock surface 83 of the lock body 82 is automatically brought into contact with the locked surface 71 of the locked body 7. Locked. As shown in FIG. 1 which is a plan view, the locking device 8 having the release operation element 80 is located on the inner side of the outer contour KM which forms a contour line defining the appearance of the bed device (bed body 1) in the plan view. Has been placed. Therefore, the release operation element 80 of the lock device 8 is disposed inside the inner edge 1 i of the bed body 1. For this reason, against the intention of the user, it is prevented that other objects hit the release operation element 80 of the lock device 8. Therefore, unless the user with the positive intention to unlock the lock device 8 operates the release operation member 80 of the lock device 8, the lock device 8 is prevented from being accidentally unlocked. Yes. In particular, as shown in FIG. 16, a recess 380 is formed in the floor plate 3, and the unlocking operator 80 for releasing the lock is located inside the recess 380 formed in the swing end 3 h of the floor plate 3. Arranged and concealed. For this reason, the release operation element 80 of the lock device 8 is prevented from being erroneously operated by hitting another object. As a result, the lock device 8 is prevented from being accidentally unlocked. Further, the mattress MA placed on the upper surface 31 of the floor board 3 can further conceal the release operation element 80 of the lock device 8. For this reason, the lock of the lock device 8 is prevented from being accidentally unlocked unless a user who has a positive intention to unlock the lock device 8 operates the release operation member 80 of the lock device 8. ing. In addition, although the release operation element 80 of the lock device 8 is a rotary operation type, it is not limited to this and can be a linear motion slide type.

(Main effects of the embodiment)
A description will be added for the case of storing articles in the article storage chamber 2. 4 to 7 show a state in which the floor plate 3 is closed at the article entrance / exit 20 of the article storage chamber 2. As shown in FIGS. 4 to 7, the floor plate 3 is locked to the bed body 1 in a horizontal state by the locking function of the locking device 8. For this reason, unless the lock by the lock device 8 is released, the swinging end 3h of the floor plate 3 cannot be flipped up and opened. Therefore, the user releases the lock by operating (rotating) the release operation element 80 of the lock device 8 with a finger. FIG. 16 shows a state in which the lock body 82 is unlocked by moving the lock body 82 in the unlocking direction while the floor body 3 is closed. The user lifts the swinging end 3h of the floor board 3 upward. According to the present embodiment, if the opening amount of the floor board 3 is a small opening (opening amount W1, see FIG. 8), in this state, if the article is a small size, the article is removed from the article entrance / exit 20. It can be stored in the article storage chamber 2. Since the first damper cylinder 55 and the second damper cylinder 65 have the throttle function and the damper function as described above, the floor plate 3 is prevented from suddenly dropping, and safety is improved.

  As described above, when the opening amount of the floor board 3 is a small opening amount (opening amount W1, see FIG. 8), it is advantageous for drying the inside of the article storage chamber 2 or making a bed. Therefore, when the user does not use the bed apparatus for a long time (for example, immediately after getting up to the next bedtime), the opening amount of the floor board 3 remains the small opening amount (see the opening amount W1, FIG. 8). If maintained by the floor board drop suppressing mechanism 53, the inside of the article storage chamber 2 can be dried during that time. In the case of the above-mentioned bed making, in consideration of the work of putting the folded portion of the bedcloth around the lower surface MA10 (see FIG. 15) of the mattress MA, the posture of the operator, the end of the mattress MA placed on the floor board 3, There is an advantage that it is easier for the worker to lift the bed from the height position of the normal bed apparatus. In this case, the burden on the waist of the worker who makes the bed is also reduced. Therefore, the bed apparatus of the present embodiment is suitable for bed making because the floor board 3 can be maintained in a small opening (opening amount W1, see FIG. 8).

  According to the present embodiment, the third floor board drop suppressing mechanism 53 has a latch function for holding the posture of the floor board 3 in a small opening (opening amount W1, see FIG. 8). For this reason, the attitude | position of the floor board 3 can be hold | maintained in the position from which the opening amount of the floor board 3 becomes small opening (refer opening amount W1, FIG. 8). In this state, if the article is small in size, the article can be stored in the article storage chamber 2 from the article entrance 20. Further, when the floor board 3 is flipped up to further increase the opening amount of the floor board 3, the user raises the swing end 3h side of the floor board 3 and further raises it in the arrow Y1 direction. Also in this case, the user may grasp the upper handle 38U attached to the upper surface 31 of the floor board 3 with a finger. As described above, as the floor plate 3 is lifted, the fluid (gas or oil) in the first damper cylinder 55 generates a flow resistance, and the first forward passage chamber 565 and the first passage chamber 565 are in contact with each other. It flows between the first return path chamber 567. Similarly, the fluid in the second damper cylinder 65 flows between the second forward chamber 665 and the second backward chamber 667 via the second throttle passage 668 while generating flow resistance. This prevents sudden jumping of the swinging end 3h of the floor plate 3 and enhances safety. Then, as shown in FIG. 9, the swing end 3h of the floor plate 3 further rises upward (in the direction of arrow Y1), so that the article entrance / exit 20 of the article storage chamber 2 is further opened. In this way, when the opening amount of the floor board 3 is a large opening (opening amount W2, see FIG. 9), even if the article is large (for example, a ski board), the article is sent from the article entrance / exit 20 to the article. It can be stored in the storage chamber 2. In this case, as shown in FIG. 9, the lower surface 33 of the floor plate 3 is spaced apart from the rolling roller 59 r at the upper end of the first operating arm 59 and is positioned above. When the opening amount of the floor board 3 is W2, the third floor board fall suppressing mechanism 53 has a latch function for holding the floor board 3 in its posture. For this reason, the attitude | position of the floor board 3 can be hold | maintained in the position where the opening amount of the floor board 3 becomes large opening (opening amount W2). In this state, even a large article such as a ski can be conveniently stored in the article storage chamber 2 from the article entrance 20 in a convenient manner. As described above, according to the present embodiment, the opening amount of the floor board 3 can be switched between W1 and W2 and a plurality of stages (two stages). For this reason, a form (FIG. 8) in which the floor board 3 is opened to a position (opening amount W1, see FIG. 8) suitable for drying or bed making of the article storage chamber 2 or a large-sized storage article (such as a ski board) is used. It can switch to the form (FIG. 9) accommodated in the article storage chamber 2 from the article entrance / exit 20, and versatility can be improved.

  Furthermore, according to the present embodiment, the upper handle 38U that is operated by hand to move the floor plate 3 in the flip-up direction is provided on the upper surface 31 of the floor plate 3 on the swing end 3h side on the flip-up side. . For this reason, even if the weight of the floor board 3 is heavy, a manual operation for moving the floor board 3 in the flip-up direction is facilitated. Further, a lower handle 38D for lowering the raised floor plate 3 in the direction opposite to the flip-up direction is provided on the lower surface 33 of the floor plate 3 on the swing end 3h side on the flip-up side. For this reason, even a user who has no power (an elderly person, a disabled person, a woman, etc.) can easily open and close the floor board 3. In particular, according to the present embodiment, the first opening / closing speed suppressing mechanism 51 and the second opening / closing speed suppressing mechanism 52 that prevent the floor plate 3 from being suddenly dropped are provided. As described above, the first damper cylinder 55 of the first opening / closing speed suppression mechanism 51 and the second damper cylinder 65 of the second opening / closing speed suppression mechanism 52 are damper functions caused by flow resistance of fluid (gas, oil, etc.). Therefore, the opening / closing speed of the floor board 3 is suppressed. In this case, when the floor plate 3 is opened and closed, it is necessary to give the floor plate 3 a force that overcomes the fluid flow resistance in the first damper cylinder 55 and the second damper cylinder 65. Even under such conditions, the upper handle 38U and the lower handle 38D are provided on the swing end 3h side of the floor plate 3 on the side where the swing radius on the flip-up side is large. Opening and closing operation of the floor board 3 becomes easy. In particular, when the opening angle of the raised floor board 3 (opening amount W2 shown in FIG. 9) is large, a small user is difficult to reach the floor board 3, and thus it is difficult to lower the floor board 3. . In the present embodiment, even in such a case, the lower handle 38D is provided on the lower surface 33 of the swing-up side 3h side of the floor plate 3, so that the floor plate 3 is lowered and closed manually. Easy to operate.

  In addition, according to the present embodiment, the release operator 80 is disposed on the inner side of the outer contour KM of the bed body 1. For this reason, the possibility that a user's leg existing outside the bed body 1 or another object moving in the vicinity of the bed body 1 will hit the release operation element 80 of the lock device 8 is reduced. Therefore, the release operation member 80 of the lock device 8 is operated by a user who has a positive intention to release the lock, which is advantageous in reducing the possibility of the release operation member 80 being operated unexpectedly. In other words, the floor plate 3 has a window opening 38t that opens on the upper surface 31 (mounting surface) on which the mattress MA (bedding) is placed, and is a recess formed between the upper surface 31 and the lower surface 33 of the floor plate 3. 380 is provided, and the release operation element 80 of the lock device 8 is disposed inside the recess 380 of the floor plate 3 while facing the window opening 38t. The release operator 80 is disposed inside the outer contour KM of the bed body 1 and is disposed inside the recess 380 of the floor plate 3 while facing the window opening 38t. For this reason, the possibility that a user's leg existing outside the bed body 1 or another object moving in the vicinity of the bed body 1 will hit the release operation element 80 of the lock device 8 is reduced. Therefore, the release operator 80 of the lock device 8 is operated by a user who has a positive intention to release the lock, which is advantageous in reducing the possibility of the release operator 80 being operated unexpectedly. In particular, the mattress MA is not placed on the floor plate 3 even when the fluid cylinders 55 and 65 that exert the spring force for operating the floor plate 3 in the flip-up direction are provided in the bed body 1. In this case, it is possible to avoid the possibility that the floor plate 3 jumps unexpectedly.

  The longitudinal reinforcement molded product 12 described above is formed by extrusion molding or pultrusion molding, and an advantage that the sub-mounting portion 126 on which the bottom plate 19 is placed can be molded integrally with the longitudinal reinforcement molded product 12 is obtained. Further, since the longitudinal reinforcing molded product 12 has high bending rigidity and high strength, the thickness TA (see FIG. 2) of the side board 10 itself can be reduced, the side board 10 can be thinned, and the bed apparatus can be installed in a narrow room. It is advantageous to install.

  FIG. 18 shows a second embodiment. The present embodiment basically has the same configuration and the same function and effect as the first embodiment. A common code | symbol is attached | subjected to a common site | part. In the following, different parts will be mainly described. However, the lock device 8B includes a rotary release operator 80B, and a lock body 82 that can be advanced in the lock direction (arrow E1 direction) and retracted in the lock release direction (arrow E2 direction) by the rotation of the release operator 80B. And have. As shown in FIG. 18, the lock body 82 is connected to the release operator 80 by an intermediate link 829. The lock body 82 is pulled by a biasing spring 86B, which is a tension spring, and is constantly biased in the lock direction (the direction of the arrow E1). The lock surface 83 of the lock body 82 of the lock body 82 is covered by the locked body 7. Locked to the lock surface 71. In this state, the floor board 3 is locked to the bed body 1, and the floor board 3 cannot be opened upward. When the user rotates the release operator 80B in the unlocking direction (arrow R2 direction), the lock body 82 moves backward in the unlocking direction (arrow E2 direction). As a result, the lock body 82 of the lock body 82 is released from the lock body 7, so that the floor board 3 is unlocked and the floor board 3 can be flipped up. When the user's finger or the like is detached from the release operator 80, the lock body 82 is automatically advanced in the lock direction (arrow E1 direction) by the urging force of the urging spring 86B, and can be locked.

  19 to 22 show a third embodiment. The present embodiment basically has the same configuration and the same function and effect as the first embodiment. A common code | symbol is attached | subjected to a common site | part. In the following, different parts will be mainly described. As shown in FIG. 20, a finger insertion groove 30 (manual operation portion) into which a finger HF can be inserted is formed on the floor plate 3 on the swing end 3 h side close to the foot board 17. For this reason, the weight of the oscillating end 3h having a large oscillating radius is reduced, and there is an advantage that the moment when the oscillating end 3h is lifted can be reduced. Furthermore, since the rocking end 3h is on the leg side, not on the bedside of the sleeping person, there is little load on the sleeping person, and even if the concave finger insertion groove 30 is formed on the rocking end 3h of the floor board 3, there is no problem. Absent. The finger insertion groove 30 communicates with the gap 4c on the footboard 17 side, the recess 380, and the window opening 38t. As shown in FIG. 19, the finger insertion groove 30 extends in the width direction (arrow DE direction) along substantially the entire width of the floor board 3. Therefore, the length of the finger insertion groove 30 is indicated as LW (see FIG. 19). For this reason, a finger may be inserted into one end 30a in the length direction of the finger insertion groove 30, and the floor plate 3 may be flipped up and down. Alternatively, a finger may be inserted into the other end 30 c in the length direction of the finger insertion groove 30 to operate the floor plate 3 to be flipped up and down.

  As shown in FIG. 20, the locked body 7 is fixed to the footboard 17 in the bed main body 1. A lock device 8 that can be locked and engaged with the locked body 7 is attached to the swing end 3 h side of the floor plate 3. In particular, the locking device 8 is attached to an intermediate region in the width direction (arrow DE direction) of the floor plate 3 on the swing end 3h side of the floor plate 3 (FIG. 19). As shown in FIG. 20, the floor plate 3 has a recess 380 formed inside the floor plate 3 and having a window opening 38 t so as to penetrate the upper surface 31 and the lower surface 33 of the floor plate 3. The window opening 38 t is opened on the upper surface 31 of the floor plate 3 and communicates with the finger insertion groove 30. The lock device 8 includes a rotary release operation element 80 disposed in the recess 380 of the floor plate 3, a lock body 82 that is locked to the locked body 7 and is unlocked by the rotation operation of the release operation element 80. In order to rotate the release operation element 80, the release operation element 80 has a handle-like manual operation unit 89 that protrudes radially outward from the release operation element 80 and is positioned in the recess 380. As can be understood from FIG. 22, a finger is inserted into the window opening 38t opened on the upper surface 31 of the floor board 3, and the manual operation unit 89 is operated to rotate the release operator 80 about the axis P1 in the unlocking direction. If operated, the lock by the lock device 8 can be released. As shown in FIG. 22, the manual operation unit 89 faces the window opening 38 t of the floor plate 3 while being housed inside the floor plate 3. For this reason, the manual operation unit 89 can be operated by a finger from the upper surface 31 side of the floor board 3. Therefore, the manual operation unit 89 has both a function of releasing the lock by the lock device 8 and a handle function used when the floor plate 3 is flipped up.

  In addition, as shown in FIG. 20, if the user's finger HF is inserted into the finger insertion groove 30 of the swing end 3h of the floor board 3, the swing end 3h side of the floor board 3 is lifted up and released, The rocking end 3h side of the floor board 3 can be lowered and closed. For this reason, the finger insertion groove 30 can function as a flip-up operation unit that moves the swinging end 3h of the floor plate 3 up and down. If such a finger insertion groove 30 is provided, the lower handle 38D mounted in the first embodiment can be eliminated. As described above, since the finger insertion groove 30 extends substantially the entire width of the floor board 3, it is easy to operate even for a user who has difficulty in one of the left and right arms.

  In a state where the floor board 3 is in a horizontal state and the article entrance / exit 20 of the article storage chamber 2 is closed, the floor board 3 is locked to the foot board 17 of the bed body 1 so that it cannot be lifted and opened with respect to the bed body 1.

A gap 4 (4c) having a gap width t2 is formed. Therefore, when the swinging end 3h of the floor board 3 is flipped up, as shown in FIG. 20, the user inserts a finger HF (see FIG. 20) through the gap 4 (4c), and the swinging end 3h of the floor board 3 is moved. It can be flipped up (in the direction of arrow Y1). When unlocking the floor plate 3 described above, as shown in FIG. 20, if the finger HF inserted from the gap 4 is inserted into the finger insertion groove 30, the finger HF can reach the manual operation unit 89 of the lock device 8. It is also possible to release the lock of the lock device 8 by rotating the manual operation portion 89 and rotating the release operator 80 about the axis P1.

  In other words, the release operator 80 of the lock device 8 can be operated by the finger HF inserted from the finger insertion groove 30 of the floor board 3. The release operator 80 is disposed on the inner side of the outer contour KM of the bed body 1 and can be operated by a finger HF inserted from the finger insertion groove 30 of the floor board 3. Therefore, it is possible to reduce the possibility that the release operation element 80 of the lock device 8 is rotated unexpectedly. Therefore, the release operator 80 of the lock device 8 is operated by a user who has a positive intention to release the lock, which is advantageous in reducing the possibility of the release operator 80 being operated unexpectedly. . The gap width t2 described above is set larger than the thickness of the finger HF so as not to pinch the finger HF, and is set to 25 mm or more and 30 mm or more. As shown in FIG. 19, the side board 10 of the bed main body 1 is formed with an opening 100s formed along the width direction of the bed apparatus. The opening 100s is formed at the upper end of the longitudinal reinforcing molded article 12 and the upper end of the decorative member 14, and communicates the outer KN and the groove 4 (4a). If dust or the like accumulates in the groove 4 (4a), the dust or the like can be discharged using the opening 100s.

  23 to 25 show a fourth embodiment. The present embodiment basically has the same configuration and the same function and effect as the first embodiment. A common code | symbol is attached | subjected to a common site | part. In the following, different parts will be mainly described. As shown in FIG. 23, the floor board drop restraining mechanism 5 includes a second opening / closing speed restraining mechanism 52 and a third floor board fall restraining mechanism 53 that holds the floor board 3 in a flip-up posture. The second opening / closing speed suppressing mechanism 52 includes a second damper cylinder 65 having a damper function. The second damper cylinder 65 has a second cylinder 66 and a second piston rod 67 slidably fitted to the second cylinder 66. The second cylinder 66 is pivotally supported by a first connecting member 535 provided on the lower surface 33 of the floor board 3 so as to be swingable in the vertical direction by a pin 66p. A reinforcing member 120c is fixed to the longitudinal reinforcing molded article 12 by fixing means such as welding. The lower end portion of the second piston rod 67 is pivotally supported by the reinforcing member 120c by a pin 67p.
