Description

  The present invention relates to a bed apparatus in which a mounted body such as a handrail or a side rail is provided on a side frame of a bed frame.

  In general, a bed apparatus is configured such that a headboard is connected to one longitudinal end of a pair of side frames and a footboard is connected to the other end. Between the pair of side frames of the bed frame, a floor plate is constructed with both ends in the width direction engaged with a receiving bar provided on the inner surface of the side frame. And a mattress is mounted on this floor board.

  When the bed apparatus is used by an elderly person or a physically handicapped person, the side member is provided with a handrail for the user to get up from the mattress or to hold it when he lies. In addition, a side fence is provided to prevent the user from falling off the mattress while sleeping or to prevent the comforter from falling off. A table for a user to place small items may be attached to the side frame instead of a handrail or a side fence.

  The attached body such as the handrail, side rail or table may be required to be provided on the user's head side or on the foot side. It is required to be removed from the side frame so as not to disturb the user of the bed apparatus. In other words, the mounted body is required to be changeable and detachable from the side frame of the bed apparatus.

Patent Document 1 discloses that a handrail is provided on a side frame of a bed frame. That is, in Patent Document 1, a pair of attachment holes that are opened at the upper end surface of the side frame is formed, and a pair of leg portions provided on the inverted U-shaped handrail are formed in the attachment holes.

  By the way, the bed apparatus is roughly classified into a hospital use and a home use, and the bed apparatus for the hospital has a sufficient strength because the bed frame is mostly made of metal. Therefore, a handrail, a side fence, etc. can be firmly attached to the side frame of the metal bed frame. However, since the bed frame for hospitals is made of metal, the appearance is very bad in appearance. For this reason, as a home bed apparatus, harmony with other furniture in the room may be impaired, and it may be difficult to use.

  On the other hand, in the case of a bed device for home use, most of the bed frame is made of wood, which is better in appearance than a metal hospital bed device. However, as shown in Patent Document 1, a structure in which an attachment hole is formed in a wooden side frame and a leg is inserted into the attachment hole to attach a handrail, the user gets on and off the bed apparatus. When the load of the user holding the handrail is applied to the side frame, the wooden side frame may be bent outward by the load.

If the side frame bends outward, the handrail will also swing outward, which may give the user a sense of anxiety.
In addition, if the mounting holes are formed in the side frames and the handrail legs are inserted into the mounting holes, the portion of the side frame where the mounting holes are formed is stronger than the other portions. Decrease significantly. Therefore, when the load applied to the handrail becomes large, there is a possibility that the portion of the side frame where the attachment hole is formed is damaged.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a bed apparatus that is excellent in appearance and that allows a member to be attached to be firmly attached to a side frame without causing the side frame to bend.

The present invention is a bed apparatus comprising a bed frame having a pair of side frames and a mounted body that is detachably provided on the side frames,
The side frame is constituted by a lower member and an upper member having a horizontal portion that is provided on the upper end of the lower member via a metal intermediate member and protrudes outward in the width direction of the bed frame,

One end and the other end of the pair of legs 5 corresponding to each other in the width direction of the bed frame 1 are connected by a connecting rod 6 (only the connecting rod at the other end is shown). Each pair of legs 5 connected by the connecting rod 6 can be held at an arbitrary inclination angle by a holding mechanism (not shown). Thereby, the height of the bed frame 1 can be adjusted by changing the inclination angle of the leg 5.

  As shown in FIGS. 6 to 8, the side frame 2 has an intermediate member 11 made of a metal square pipe. On the upper surface of the intermediate member 11, an upper member 12 formed in a band plate shape with wood is provided, and on the lower surface, a lower member 13 similarly formed in a band plate shape with wood is provided. The intermediate member 11 is set to have a larger width dimension along the width direction of the bed frame 2 than the upper member 12 and the lower member 13.

  The upper member 12 and the lower member 13 are arranged with the outer surfaces flush with the outer surface of the intermediate member 11. And the longitudinal direction intermediate part of the upper member 12, the lower member 13, and the intermediate member 11 fixes one side to the inner surface of the upper member 12 and the lower member 13 with the screw 15 as shown in FIG. 5 and FIG. Are joined together by a pair of upper and lower first connecting members 16 having an L-shaped cross section.

  The longitudinal ends of the upper member 12, the lower member 13, and the intermediate member 11 are connected by a pair of upper and lower second connecting members 17 as shown in FIG. Like the first connecting member 16, the second connecting member 17 has an L-shaped cross section. One side of the second connecting member 17 is fixed to the inner surface of the upper member 12 and the lower member 13 with a screw 15. Are fixed to the upper and lower surfaces of the intermediate member 11 by welding.

  Further, as shown in FIG. 9, at the side ends of the pair of second connecting members 17, connecting pieces 18 positioned at both ends in the longitudinal direction of the intermediate member 11 are bent in an L shape. The connecting piece 18 integrally connects a pair of upper and lower connecting members 17.

  The connecting piece 18 of the second connecting member 17 located at one end in the longitudinal direction of the intermediate member 11 is screwed and fixed to both ends in the width direction of the inner surface of the head board 3 and the second connecting member 17 located at the other end. The connecting piece 18 is fixed by screws to both ends in the width direction of the inner surface of the end board 4. Thereby, the bed frame 1 is configured.

  A horizontal portion 21 extending outward in the width direction of the bed frame 1 is formed on the upper end portion of the side frame 2 in the height direction, that is, the upper member 12. The horizontal portion 21 is formed with a plurality of insertion holes 22 penetrating in the thickness direction at predetermined intervals with respect to the longitudinal direction.

  The end frame 4 is formed with a horizontal portion 4 a whose upper surface is the same height as the upper surface of the horizontal portion 21 of the side frame 2 and extends outward in the longitudinal direction of the bed frame 1. Further, the width dimension of the head board 3 is set to be the same as the width dimension between the tips of the horizontal portions 21 of the pair of side frames 2.

  As shown in FIG. 6, a first mounting hole 23 is formed on the outer surface of the side frame 2 in the width direction of the intermediate member 11 at a position corresponding to the insertion hole 22 formed in the horizontal portion 21. Yes. A second mounting hole 24 having a smaller diameter than the first mounting hole 23 is formed on the inner surface of the intermediate member at a position facing the first mounting hole 23.

  As shown in FIGS. 7 and 8, a pair of support members 25 are attached and fixed at predetermined intervals on the outer surface of the intermediate member 11 and on the lower surface side of the horizontal portion 21 of the upper member 12. The support member 25 is formed with a support hole 26 opened on the top surface, a connecting shaft 27 having a screw 27a formed at the tip is projected on the back surface, and an engagement recess 28 is formed.

  The pair of support members 25 are attached to the outer surface of the intermediate member 11 via a strip-shaped connecting member 31. A pair of positioning holes 32 are formed at both longitudinal ends of the connecting member 31, and the connecting shaft 27 is inserted into the positioning holes 32.

  Engaging pins 33 that engage with the engaging recesses 28 are provided at both ends of the connecting member 28. As a result, the pair of support members 25 are held non-rotatably on the outer surface of the intermediate member 11 by engagement between the engagement recess 28 and the engagement pin 33 at a predetermined interval.

  The distance between the pair of positioning holes 29 formed in the connecting member 27 is set to, for example, twice the distance between the first mounting holes 23 formed in the intermediate member 11. Thereby, the connecting shaft 27 of the pair of support members 25 held by the connecting member 27 is inserted into the pair of first mounting holes 23 of the intermediate member 11 as shown in FIG. Protrudes from the second mounting hole 24 toward the inner surface of the intermediate member 11.

  A cap nut 35 is screwed into the male screw portion 27 a protruding from the second mounting hole 24 via two washers 34. Thereby, the support member 25 is detachably attached and fixed to the outer surface of the intermediate member 11.

  The support holes 26 of the pair of support members 25 attached and fixed to the outer surface of the intermediate member 11 are opposed to the pair of insertion holes 22 formed in the horizontal portion 21 of the upper member 12. A pair of leg portions 38 provided on a side fence 37 as an attached body is inserted into the pair of insertion holes 22 facing the pair of support holes 26.

  The pair of leg portions 38 inserted into the insertion hole 22 is inserted and supported in the support hole 26 of the support member 25 positioned opposite to the insertion hole 22. Thereby, the side fence 37 is supported by the support member 25 attached to the side frame 2 of the bed frame 1.

  Among the plurality of insertion holes 22 of the side frame 2, a cap 41 made of the same material as the upper member 12 of the side frame 2 is attached to the insertion hole 22 in which the leg portion 38 of the side fence 37 is not inserted. The As shown in FIG. 6, the cap 41 is formed with a screw 42 for opening at the lower end surface. After the cap 41 is mounted in the insertion hole 22, the fixing bolt 43 is larger than the insertion hole 22 in the female screw 42. Screwed through a washer 44 having a diameter. Thereby, the cap 41 is held and fixed in the insertion hole 22.

  A floor plate (not shown) is erected on both ends in the width direction so as to protrude from the inner surface of the intermediate member 11 forming the pair of side frames 2 of the bed frame 1. A mattress 45 is placed on the upper surface of the floor plate as shown in FIG.

  Although not shown in detail, the floor board may be divided into a plurality of floor portions, the floor portions may be connected to each other so as to be rotatable, and may be configured to be raised by an electric back raising mechanism. . Furthermore, the bed frame 1 may be configured such that the height can be adjusted by an electric vertical drive mechanism instead of the leg body 5.

  According to the bed apparatus configured as described above, the side frame 2 of the bed frame 1 is divided into the intermediate member 11, the upper member 12 and the lower member 13, and a metal square tube is used for the intermediate member 11. The member 12 and the lower member 13 were made of wood. The upper member 12 is provided with a horizontal portion 21 that protrudes outward in the width direction of the bed frame 1.

  Therefore, since the side frame 2 is reinforced by the metal intermediate member 11, it can be provided with sufficient strength that is difficult to bend. Therefore, if a pair of support members 25 are attached to the side frame 2 and the leg portions 38 of the side fence 37 are inserted and supported on the support members 25, even if a user load is applied to the side fence 37, The side frame 2 can be prevented from being bent outward by the load. That is, the side fence 37 can be firmly attached to the side frame 2.

  Moreover, the leg portion 38 of the side fence 37 is inserted and supported not only in the support hole 26 of the support member 25 but also in the insertion hole 22 formed in the horizontal portion 21 of the upper member 12. This also makes it possible to reliably support the leg portion 38.

  The upper member 12 of the side frame 2 is provided with a horizontal portion 21 that protrudes outward in the width direction of the bed frame 1. Therefore, since the metal intermediate member 11 of the side frame 2 is covered with the horizontal portion 21 of the wooden upper member 12, the metal intermediate member 11 does not stand out.

  As a result, the side frame 2 has a wooden appearance, so even if the metal intermediate member 11 is used for the side frame 2, the appearance of the bed frame 1 is not greatly impaired. That is, even if the bed apparatus having the above-described configuration is installed in a household room, there is no sense of discomfort due to loss of harmony with other furniture.

  A plurality of insertion holes 22 are formed in the horizontal portion 21 of the side frame 2 at predetermined intervals in the longitudinal direction. Therefore, the attachment position of the side fence 37 in the longitudinal direction of the side frame 2 can be arbitrarily set.

  The insertion hole 22 in which the leg portion 38 of the side fence 37 is not inserted is closed by a cap 41 made of the same material as the upper member 12. For this reason, even if a plurality of insertion holes 22 are formed in the horizontal portion 21 of the side frame 2 along the longitudinal direction, the unused insertion holes 22 are not exposed on the upper surface of the horizontal portion 21. Is good.

  Furthermore, by providing the upper member 12 with the horizontal portion 21 protruding outward, a predetermined interval is formed between the protruding end and the outer surface of the side frame 2. That is, a space portion is formed below the horizontal portion 21. Therefore, since the user is placed on the mattress 45, when the user approaches the side frame 2, the accessible distance is limited by the tip (protruding end) of the horizontal portion 21. Can be prevented.

  In addition, when the user descends from the mattress 45, the position where the user descends is located at a predetermined distance from the outer surface of the side frame 2 by the horizontal portion 21. 2 can be prevented from hitting the outer surface.

  Further, the end frame 4 is provided with a horizontal portion 4 a whose upper surface is the same height as the horizontal portion 21 of the side frame 2. For this reason, the bed frame 1 is surrounded by the horizontal portions 21 and 4a except for one end on the headboard 3 side. In this case, it is possible to prevent the toes and the heel from hitting the outer surface of the end frame 4.

  In the above embodiment, the bed apparatus in which the side fences are provided on both sides of the bed frame is taken as an example. However, the side fence may be provided only on one side, and the attached body may be replaced with the side fence. A handrail or a table may be used. In the case of a table, there may be one leg, and in that case, only one support member may be provided on the side frame.
