Description

  The present invention relates to an assembly structure of a mattress, a bed pad and a sheet in a bed that can be raised up.

2. Description of the Related Art Conventionally, as one form of a bed, a bed that can raise and lower a floor as needed to care or can raise and lower a floor and relax in an easy posture has been widely known.
However, in such a bed, when the floor portion is raised and lowered, the mattress forming the floor portion moves to the foot side of a person (hereinafter referred to as a user) who lies on the floor portion with respect to the bottom supporting the mattress. As a result, the user may be misaligned, causing discomfort to the user, and each time the floor portion is operated, troubles such as reattachment of the mattress to the bottom may occur. At the same time, there are problems such as misalignment of bed pads and sheets laid on the mattress.

Therefore, conventionally, a bed has been proposed that employs the following locking method for the bottom of the mattress.
First, in the bed of the first form, the mattress is configured by connecting the head-side mattress and the leg-side mattress, and the strap-like locking for locking the head-side mattress to the head-side bottom. The head portion is provided obliquely from the head side end portion toward the side portion, the locking portion is locked to the head side bottom, the head side mattress is locked to the head side bottom, and the legs A method has been proposed in which a metal fitting as a means for preventing misalignment is provided on the bottom of the side, the position of the leg side mattress is restricted with respect to the bottom of the leg side, and the leg side mattress is locked to the leg side bottom. (For example, refer to Patent Document 1).
Further, in the bed of the second form, a method has been proposed in which a non-slip member is provided on a part of the mattress contact surface side of the bottom and the mattress is prevented from shifting with respect to the bottom by the anti-slip member. (For example, refer to Patent Document 2).
JP 2001-258952 A Japanese Patent Application Laid-Open No. 07-075657

However, in the locking method of the first embodiment, the head-side mattress is shifted from the head-side bottom at the locking portion except for the direction opposite to the mounting direction of the head-side mattress with respect to the head-side bottom. Although it is mounted so as not to move, no special countermeasure is taken against shifting in the direction opposite to the mounting direction, that is, in the mounting releasing direction. In addition, the leg mattress is attached by the metal fittings so that the leg mattress does not move with respect to the leg bottom in the mounting direction of the leg mattress with respect to the leg bottom. No special measures are taken against shifting in other directions. Therefore, when a user touches the mattress when going up and down on the floor or when a caregiver assists the user, there is an external force in a direction in which no special measures are taken against the movement of the mattress with respect to the bottom. When acting on the mattress, the mattress may move or the latch of the mattress on the bottom may be released. For this reason, the user or caregiver needs to be careful not to move the mattress so that the mattress does not move, and there is a problem that the use of the bed becomes complicated. In addition, when the floor is raised and lowered without noticing that the mattress is unlocked from the bottom, the mattress may not contact the other components of the bed to perform a predetermined operation. In addition, there is a problem that the mattress moves to the user's foot side, which causes discomfort to the user.
In the second form of the locking method, an anti-slip member is interposed between the bottom and the mattress so that the mattress does not move when the mattress is in contact with the bottom. No particular countermeasure is taken against the movement of the lens in a direction away from the bottom. Therefore, when the floor portion is raised and lowered, the mattress is easily separated from the bottom, and the mattress is separated from the bottom, so that there is a problem that the anti-slip effect of the anti-slip member is lost and the mattress moves.
Furthermore, since any of the above-described locking methods has a problem that the mattress moves, the bed pad or the sheet laid on the mattress also moves. Therefore, there is a problem that it takes time to re-lay in a predetermined state other than when changing the bed pad or the sheet so that the user can spend comfortably on the floor.
Therefore, the problem to be solved by the present invention is that the mattress assembly structure prevents the mattress from moving with respect to the bottom even if the floor portion is deformed, and the predetermined mounting state even if the floor portion is deformed. It is an object of the present invention to provide a bed that can be lifted up and provided with an assembly structure of bed pads and sheets laid on the mattress that is held.

According to the first aspect of the present invention, the bottom supporting the mattress forming the floor is divided into at least a back bottom, a waist bottom, and a leg bottom so that the back bottom can be raised and lowered, and the leg bottom is below the waist bottom. In the bed that can be raised to the back, the mattress is divided into an upper body mat and a leg mat, and a non-slip member is provided on the upper surface of at least the waist bottom of the bottom, and the upper A frame cloth of the back bottom is inserted from the front side into a space formed by a band cloth fastened to the rear side of the middle part of the lower surface of the mat on the body side, and the bag cloth fastened to the front part of the lower surface of the lower side of the upper body mat The upper body mat was attached to the back bottom and the waist bottom by inserting the support frame of the waist bottom from the front side into the formed bag part, and was fixed to the both sides of the lower side of the leg side mat By writing each difference sides of the leg bottom frame member in the bag portion formed by the cloth, characterized in that the assembling structure of the mattress attaching the leg mat leg bottom.

It can move down the waist bottom. Further, since the middle part of the bed pad is fixed to the waist bottom, the bed pad does not move when the floor part stands up from the state of the chair. Therefore, even if the bed pad is deformed or an external force is applied to the bed pad, the bed pad can be properly attached. Therefore, it is possible to ensure that the user can always comfortably stay on the bed pad. Further, it is possible to eliminate the trouble of re-laying the bed pad in a predetermined state other than at the time of replacement.
Further, since the bed pad is fixed to each bottom while pressing the mattress against each bottom, the mattress can be more firmly fixed to each bottom by attaching the bed pad. it can.

  According to the invention of claim 5, since the front side of the sheet is fixed to the leg bottom together with the bed pad, when the leg bottom is stored below the waist bottom, the sheet is moved along with the movement of the leg bottom. Can move the front of the lower part of the waist bottom. In addition, since the middle portion of the sheet is fixed to the waist bottom, the sheet does not move when the floor portion stands up from the state of the chair. Therefore, even when the sheet is deformed, or when an external force is applied to the sheet, the sheet can be properly attached. Therefore, the user can always spend comfortably on the sheet. Furthermore, it is possible to eliminate the trouble of re-laying the sheets in a predetermined state other than at the time of replacement.

  According to the sixth aspect of the present invention, since the band cloth and the bag cloth provided on the upper body side mat and the leg side mat of the mattress expand and contract, the upper body side mat and the leg side mat are further attached to each bottom. Can be installed conveniently. Furthermore, in a state where the body-side mat and the leg-side mat are attached to the bottoms, the band cloth and the bag cloth can tighten the predetermined portions of the bottoms, and a stronger attachment state can be secured. Similarly, since the sheet cloth of the sheet expands and contracts, the sheet can be conveniently attached to the upper body side mat and the bed pad, and a more firmly attached state can be secured.

In a bed that can be raised up, the mattress that forms the floor is attached as follows. First, the mattress is divided into an upper body side mat and a leg side mat.

Thereafter, the opening member 21f is set to a fixed state, and is attached to the leg bottom 11 as shown in FIG.
In this way, the mattress 1 is fixed to the bottoms 7, 9, and 11, and the mattress 1 is attached to the top surfaces of the bottoms 7, 9, and 11, as shown in FIG.

Thus, when the mattress 1 is attached to the bottoms 7, 9, and 11, the predetermined portions of the bottoms 7, 9, and 11 are different from the bag portions 20g, 20g, 20g, 21e, and 21e provided on the mattress 1, respectively. Or simply inserted through the space 20e provided in the mattress 1, and can be easily attached or detached. Further, by providing the opening member 21f on at least one bag cloth 21d of the leg-side mat 21, the frame frame 11b side portion of the leg bottom 11 can be easily inserted into the two bag portions 21e, 21e. The leg-side mat 21 can be attached more easily. Further, by providing the opening member 21f, it is possible to fasten the frame frame 11b of the leg bottom 11 with the bag cloth 21d provided with the opening member 21f.
Further, the upper body side mat 20 is attached to the back bottom 9 and the waist bottom 7 in a state in which predetermined portions of the back bottom 9 and the waist bottom 7 are wrapped with the band cloth 20d and the bag cloth 20f. On the other hand, it is prevented from shifting in the forward direction, the left-right direction, and the direction away from the back bottom 9 and the waist bottom 7, that is, the direction excluding the attachment release direction of the upper body side mat 20 with respect to the back bottom 9 and the waist bottom 7. Further, the waist bottom 7 is provided with a non-slip member 19, and the anti-slip member 19 prevents the upper body side mat 20 from moving in the direction of releasing the attachment to the back bottom 9 and the waist bottom 7. Further, the leg-side mat 21 is attached to the leg bottom 11 so as to wrap a predetermined portion of the leg bottom 11 with the bag cloths 21d and 21d, so that the leg-side mat 21 does not move relative to the leg bottom 11. Therefore, when the floor is raised and lowered, the mattress 1 does not move forward with respect to the bottoms 7, 9, and 11, and the user's front displacement that occurs when the mattress 1 moves forward is prevented. It can be made so as not to cause discomfort to the user. Furthermore, since the mattress 1 is configured such that the body-side mat 20 and the anti-slip member 19 are in contact with each other, the body-side mat 20 is moved in the attachment releasing direction while separating the body-side mat 20 from the anti-slip member 19. As long as this is not the case, the upper body side mat 20 is attached so as not to move easily relative to the back bottom 9 and the waist bottom 7. Therefore, when the user is on the floor, the upper body side mat 20 and the anti-slip member 19 are in close contact with each other, so even when an external force is applied to the mattress 1 when the caregiver assists. The mattress 1 does not move. Further, even when an external force is applied when the user goes up and down on the floor with no user on the floor, the mattress 1 hardly moves. In addition, from these facts, it is possible to largely prevent the mattress 1 from being suddenly unlocked from the bottoms 7, 9, and 11. Further, since it is possible to largely eliminate the operation of the bottoms 7, 9, and 11 without noticing that the mattress 1 is moving, the mattress 1 hinders the operation of the bottoms 7, 9, and 11. It can be lost. In addition, it is not necessary for the user or caregiver to act while taking care that the mattress 1 does not move, and the bed B can be easily handled.
Further, by providing the overlapping portions 20h and 21g on the adjacent sides of the body-side mat 20 and the leg-side mat 21, respectively, the overlapping portions 20h and 21g overlap each other in plan view as shown in FIG. The wind that blows up from below can be prevented from blowing up from the gap on the adjacent side of the upper body side mat 20 and the leg side mat 21. Thereby, it is possible to prevent the user from feeling uncomfortable, and the user can spend comfortably on the mattress 1 including a plurality of divided mats. Further, by setting the overlapping portions 20h and 21g provided in the respective portions to be inclined portions 20i and 21h, the leg bottom 11 is moved downward with respect to the waist bottom 7 and moved backward to be stored below the waist bottom 7. In this case, the leg bottom 11 can be easily stored without interference between the leg-side mat 21 and the constituent members of the other bed B. Therefore, the storage means 10 can be easily configured.
In addition, the mattress 1 is configured such that the cushion members 20a and 21a and the cloth members 20b and 21b are sewn together so that the cushion members 20a and 21a can be used when the floor portion is raised and lowered or when the user moves on the floor portion. In contrast, the cloth members 20b and 21b are prevented from shifting. As a result, the user can spend more comfortably on the floor.

If a member or material having elasticity such as rubber is used for the band cloth 20d and the bag cloths 20f, 21d, and 21d of the upper body side mat 20 and the leg side mat 21, the band cloth 20d and the bag cloth are used. Since 20f, 21d, and 21d expand and contract, the upper body side mat 20 and the leg side mat 21 can be more easily attached to the bottoms 7, 9, and 11, respectively. Further, in a state where the body-side mat 20 and the leg-side mat 21 are attached to the bottoms 7, 9, and 11, the belt cloth 20d and the bag cloths 20f, 21d, and 21d fasten predetermined portions of the bottoms 7, 9, and 11, respectively. It becomes possible to secure a stronger mounting state.
Further, in this embodiment, the cushion members 20a and 21a of the upper body side mat 20 and the leg side mat 21 and the cloth members 20b and 21b covering the cushion members 20a and 21b are sewn together. In addition, an adhesive, a hook-and-loop fastener, or the like can be used as a means for wearing.
Furthermore, in the present embodiment, the overlapping portions 20h and 21g of the body side mat 20 and the leg side mat 21 are inclined portions 20i and 21h, but the body side mat 20 as shown in FIG. The overlapping portion 20h may have a step shape with the upper surface side protruding forward from the lower surface side, and the overlapping portion 21g of the leg side mat 21 may have a step shape with the lower surface side protruding backward from the upper surface side. Further, as shown in FIG. 9 (b), the overlapping portion 20h of the upper body side mat 20 has an arc shape in a side view in which the upper surface side protrudes forward from the lower surface side, and the overlapping portion 21g of the leg side mat 21 is the lower surface. In a side view in which the side protrudes rearward from the upper surface side, an arc shape may be used. Even if it does in this way, the effect similar to the superposition | polymerization part 20h and 21g used as the above-mentioned inclination part 20i and 21h can be acquired. The bed B moves the leg bottom 11 downward with respect to the waist bottom 7 and moves it backward when the leg bottom 11 is stored in the waist bottom 7. The shapes of the portions 20h and 21g are desirably such that the lower body side protrudes forward from the upper surface side on the upper body side mat 20 side, and the lower surface side protrudes rearward from the upper surface side on the leg side mat 21 side.
