Description

[Technical field]

[0001] The present invention relates to a bed having detachable side rails attached to the sides of a base. [Background technology]

[0002] Conventionally, beds have been provided with a support platform on top of a base on which a recumbent person (a person lying on the bed in a supine, lateral, prone, etc. position) lies, and side rails are provided on the sides of the base (to the sides of the support platform) in a removable manner to prevent the recumbent person or bedding from falling off the support platform.

[0003] This side fence has a pair of side fence posts facing downward at the bottom of the side fence body, and is designed to be removably attached to the side of the base by inserting the side fence posts into a pair of support holes in a support body formed on the side of the base (see, for example, Patent Document 1).

[0004] In conventional beds, a side rail storage space is provided between the board (headboard or footboard) attached to the end of the base and the receiving base so that the side rail can be stored in the bed when it is removed from the base. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2006-55529 A Summary of the Invention [Problem to be solved by the invention]

[0006] In the above-mentioned conventional bed, a pair of holders are provided for holding the side rails that are stored on a base within the side rail storage space, and each holder is formed with a holder hole for inserting the side rail support post of the side rail.

[0007] When removing the side fence that has been attached to the side of the base and is stored in the side fence storage space, the side fence is stored in the side fence storage space by inserting a pair of side fence supports formed on the side fence into respective retaining holes formed in the pair of retainers.

[0008] However, when inserting the side fence posts into the retaining holes formed in the pair of holders, it is not easy to insert a pair of side fence posts into a pair of retaining holes at the same time unless there is some margin in the diameter of the side fence posts and the diameter of the retaining holes to prevent rattling, so it is necessary to make the diameter of the retaining holes larger than the diameter of the side fence posts.As a result, there is a problem that the side fence posts rattle against the holders, making the bed occupant uncomfortable.

[0009] Furthermore, in conventional beds, when a pair of holders 38, 38 are arranged so that the regular-size side rail 36 is in the center of the width of the board 37, as shown in Figure 8(a), the side rail 36 does not protrude from the board 37. However, when a long-size side rail 39 that is longer than the regular-size side rail 36 is accommodated in a pair of holders 38, 38 arranged in this manner, one side of the side rail 39 protrudes significantly from the board 37, as shown in Figure 8(b), which causes problems such as affecting the installation space of the bed and hindering the movements of users and caregivers around the bed. In order to solve this problem, one possible method would be to shift the position of the pair of retaining bodies 38, 38 to accommodate the long-size side rail 39 so that it is centered in the width of the board 37. However, due to various reasons that prevent the spacing between the pair of side rail supports 40, 40 and the spacing between the left and right frames 41, 41 that support the bed base from being changed, one of the retaining bodies 38 would be in a position that would interfere with the bed frame 41 or the bracket 42 of the board 37, as shown in Figure 8(c), and so it would not be possible to install it, resulting in the problem that the long-size side rail 39 could not be accommodated so that it was centered in the width of the board 37. [Means for solving the problem]

[0010] Therefore, in the present invention as claimed in claim 1, a support platform on which a reclining person lies is provided on the upper part of the base, a side rail having a pair of side rail posts formed at the lower part of the side rail main body is provided on the left and / or right part of the base so that it can be attached and detached freely, and a side rail storage space for storing a side rail removed from the base is provided between a board provided at the front or rear end of the base and the front or rear end of the support platform, and the side rail stored in the side rail storage space is held by a side rail post holder which holds the side rail with one of the side rail posts, and a side rail main body holder which holds the side rail at the lower part of the side rail main body.

[0011] Furthermore, in the present invention related to claim 2, in the present invention related to claim 1, a retaining groove is formed in the side fence main body retainer to hold the lower end of the side fence main body along the lower end of the side fence main body.

[0012] In addition, in the present invention according to claim 3, in the present invention according to claim 2, an upper end opening is formed in the retaining groove whose width is greater than the thickness of the side fence body. Effect of the Invention

[0013] The present invention provides the following advantages.

[0014] In other words, in this invention, a bed is provided on top of the base where a support platform for a person to lie on is provided, and a side fence with a pair of side fence posts formed at the bottom of the side fence main body is provided on the left and / or right side of the base so that it can be attached and detached freely, and a side fence storage space for storing a side fence removed from the base is provided between a board provided at the front or rear end of the base and the front or rear end of the support platform, and the side fence stored in the side fence storage space is held by a side fence post holder that holds the side fence with one of the side fence posts, and a side fence main body holder that holds the side fence with the bottom of the side fence main body.Therefore, when a side fence that has been attached to the side of the base and used is removed and stored in the side fence storage space, one of the side fence posts of the side fence is held by the side fence post holder and the bottom of the side fence main body is placed on the side fence main body holder, and the side fence can be easily stored and also easily removed.

[0015] Furthermore, in the present invention, the side fence is held by a side fence post holder that is held by one of the side fence posts, and a side fence body holder that holds the side fence at the bottom of the side fence body.As such, the position of the side fence body holder can be set regardless of the spacing between the pair of side fence posts, and therefore not only regular-sized side fences but also long-sized side fences can be accommodated with minimal overhang of the side fence body from the width of the bed board.

[0016] In particular, when a retaining groove is formed in the side fence main body retainer to hold the lower end of the side fence main body along the lower end of the side fence main body, the wobbling of the side fence stored in the side fence storage space can be reduced.

[0017] Furthermore, if the retaining groove is formed with an upper opening that is wider than the thickness of the side fence body, there is space between the side fence body and the upper opening of the retaining groove when storing the side fence in the side fence storage space, and the side fence body can be inserted into the retaining groove even if it is slightly misaligned from the correct storage position, making the work of storing the side fence even easier.

[Figure 8] FIG. 13 is a front view illustrating a problem with the conventional technology. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, a specific configuration of the bed according to the present invention will be described with reference to the drawings.

[0020] As shown in Figures 1 to 3, bed 1 has a support 2 for supporting the body of a person lying down attached to the upper part of a base 3. For convenience, the description will be given here assuming that the foot side (right side in Figure 1) of a person lying down on bed 1 is the front side, and the head side (left side in Figure 1) is the rear side.

[0021] The bed 2 is attached to the top of the base 3 and has a rectangular flat plate shape. The bed 2 may be divided into parts that can be raised and lowered to form a reclining bed.

[0022] The base 3 has a rectangular bed frame 5 attached to the upper ends of legs 4, 4 spaced apart from each other in the front and rear direction. The bed frame 5 has front and rear frames 8, 9 attached to the front and rear ends of left and right frames 6, 7 spaced apart from each other in the left and right direction. The base 3 may be configured as a lift-up bed that raises and lowers the receiving platform 2, or may be provided with casters to form a mobile bed.

[0023] Further, the base 3 has horizontally long rectangular boards (a foot board 10 and a head board 11) detachably attached to the left and right frames 6, 7 of the bed frame 5 via brackets 12.

[0024] Furthermore, the base 3 has a pair of front and rear supports 13, 14 attached to each of the left and right frames 6, 7 of the bed frame 5 in a manner that protrudes outward with a space between them, and side rails 15, 15, 16, 16 are removably attached to each of the pair of front and rear supports 13, 14.

[0025] In addition, the long-size side rails 16 are longer in front-to-back length than the regular-size side rails 15, and when the shorter (regular-size) side rails 15 are attached to the base 3 side by side (left side of the base 3 in Figure 1), a gap is formed between the front and rear side rails 15, 15 wide enough for a reclining person to get on and off the bed 1; on the other hand, when the longer (long-size) side rails 16 are attached to the base 3 side by side (right side of the base 3 in Figure 1), there is almost no gap between the front and rear side rails 16, 16.

[0026] The side fences 15, 16 have a pair of cylindrical left and right side fence posts 19, 20, 21, 22 extending downward from the lower end of the side fence main body 17, 18 which is shaped like a horizontally elongated rectangular frame.

[0027] Although the length of the side fence main body 17 of the regular-size side fence 15 is shorter than the length of the side fence main body 18 of the long-size side fence 16, the shape and spacing of the pair of side fence supports 19, 20 of the regular-size side fence 15 are the same as the shape and spacing of the pair of side fence supports 21, 22 of the long-size side fence 16, so that both side fences 15, 16 can be freely attached and detached to either pair of supports 13, 14. In addition, the regular-size side fence 15 has a pair of side fence posts 19, 20 evenly spaced on the left and right sides of the side fence main body 17, giving it the same overhang length on the left and right and a line-symmetrical shape on the left and right, but the long-size side fence 16 has a pair of side fence posts 21, 22 on the side fence main body 18 that overhangs to one side, so that on one side of the side fence main body 18 the overhang length is the same as the overhang length of the regular-size side fence main body 17 and on the other side of the side fence main body 18 the overhang length is longer than the overhang length of the regular-size side fence main body 17.

[0028] These side fences 15, 16 can be attached to the base 3 by inserting a pair of front and rear side fence posts 19, 20, 21, 22 from top to bottom into a pair of front and rear support holes 23, 24 formed in the front and rear supports 13, 14, respectively, and can be removed from the base 3 by lifting the side fence main bodies 17, 18 upward in the attached state.

[0029] During normal use, the side rails 15, 16 are attached to the front and / or rear sides of the left and / or right side of the base 3, but when removed from the supports 13, 14 of the base 3, they can be stored in a side rail storage space 25 formed between the end of the support 2 of the bed 1 and the board (footboard 10).

[0030] In the side fence storage space 25, a side fence post holder 26 for holding the side fences 15, 16 with either one of the side fence posts 19, 21 (20, 22) of a pair of side fence posts 19, 20, 21, 22 provided on the side fences 15, 16, and a side fence main body holder 27 for holding the side fences 15, 16 at the lower parts of the side fence main bodies 17, 18 provided on the side fences 15, 16 are attached to the base 3 (front frame 8). Note that the side fence post holder 26 and the side fence main body holder 27 only need to be provided in the side fence storage space 25, and may be attached to the rear frame 9 of the base 3, or may be attached to the board (footboard 10, headboard 11) instead of the base 3.

[0031] Each side fence 15 (16) accommodated in the side fence storage space 25 is held by a side fence post holder 26 and a side fence main body holder 27.

[0032] 4, the side fence post holder 26 has through holes 28, 28 formed in the left and right sides of its hollow rectangular box shape for passing the front frame 8 therethrough, and also has two through-holes 29, 30 with circular cross-sections formed in the upper part. Note that the side fence post holder 26 may be fixed to the front frame 8 by welding or the like, even if the through holes 28, 28 for passing the front frame 8 therethrough are not provided.

[0033] The retaining holes 29, 30 have the same cross-sectional shape as the side fence posts 19, 20, 21, 22, but are slightly larger in size than the side fence posts 19, 20, 21, 22.

[0034] In this side fence post holder 26, one of the side fence posts 19, 20, 21, 22 provided on the side fences 15, 16 is inserted from above into one of the retaining holes 29, 30, thereby holding the side fence posts 19, 20, 21, 22 of the side fences 15, 16 in the retaining holes 29, 30.

[0035] As shown in FIG. 5, the side fence main body holder 27 has a mounting portion 31 formed at the bottom for mounting to the front frame 8, and two holding grooves 32, 33 formed at the top that extend parallel to the left and right.

[0036] The retaining grooves 32, 33 have a cross-sectional shape and size at their lower ends (lower half portions) that are approximately the same as the lower end shape of the side fence main bodies 17, 18 of the side fences 15, 16, and their upper end openings (upper half portions) are wider than the thickness of the side fence main bodies 17, 18, and have an inclined surface 35 that gradually narrows from the upper end opening 34, which is wider than the thickness of the lower part of the side fence main bodies 17, 18, towards the lower end (lower half portion).

[0037] In this side fence main body holder 27, the lower part of the side fence main body 17, 18 provided on the side fence 15, 16 is inserted from above into one of the holding grooves 32, 33, thereby holding the side fence main body 17, 18 of the side fence 15, 16 in the holding groove 32, 33.

[0038] In this way, with the side fence main body holder 27, when storing the side fences 15, 16 in the side fence storage space 25, it is only necessary to place (insert) the side fence main bodies 17, 18 from above into the retaining grooves 32, 33, making the storage work of the side fences 15, 16 easy.

[0039] Furthermore, since the upper end opening 34 of the side fence main body holder 27 is wider than the thickness of the lower part of the side fence main bodies 17, 18, the position of the stored side fences 15, 16 may be slightly misaligned, making the work of storing the side fences 15, 16 even easier.

[0040] Furthermore, in the side fence main body holder 27, the lower ends of the side fence main bodies 17, 18 are held by retaining grooves 32, 33 extending left and right along the lower ends of the side fence main bodies 17, 18, so that, in cooperation with the side fence support post holder 26, the rattling of the side fences 15, 16 stored in the side fence storage space 25 can be reduced.

[0041] The mounting positions of the side fence post holder 26 and the side fence main holder 27 in the side fence storage space 25 may be, for example, as shown in FIG. 6(a), such that when a long-size side fence 16 is stored in the side fence storage space 25, the long-size side fence 16 is stored evenly on the left and right of the bed 1 in a front view, and the amount of overhang from the footboard 10 is equal on the left and right. In this case, as shown in FIG. 6(b), when a regular-size side fence 15 is stored in the side fence storage space 25, the side fence 15 does not overhang on one side of the footboard 10, and only the other side of the footboard 10 has the same overhang as when a long-size side fence 16 is stored. In this case, the amount of overhang on both sides of the footboard 10 can be suppressed, and even when the long-size side fence 16 is stored, it has almost no effect on the installation space of the bed 1, and does not interfere with the actions of the user, caregiver, etc. around the bed 1.

[0042] The mounting positions of the side fence post holder 26 and the side fence main body holder 27 in the side fence storage space 25 may be such that, for example, as shown in FIG. 7(a), when a long-size side fence 16 is stored in the side fence storage space 25, one side of the long-size side fence 16 does not protrude from the footboard 10 in a front view, and only the other side of the long-size side fence 16 protrudes from the footboard 10. In this case, as shown in FIG. 7(b), when a regular-size side fence 15 is stored in the side fence storage space 25, the side fences 15 do not protrude from either side of the footboard 10. In this case, it is suitable for installing one side of the footboard 10 against the wall of the room without any gaps.

[0043] As described above, the bed 1 has a support platform 2 on the upper part of the base 3 on which a person lies, side rails 15, 16 each having a pair of side rail posts 19, 20, 21, 22 formed at the lower part of the side rail main bodies 17, 18 are detachably attached to the left and / or right side of the base 3, and a side rail storage space 25 is provided between the board (footboard 10, headboard 11) provided at the front or rear end of the base 3 and the front or rear end of the support platform 2 for accommodating the side rails 15, 16 removed from the base 3.

[0044] The side fences 15, 16 are held in the side fence storage space 25 by a side fence post holder 26 that holds the side fences 15, 16 at one of the side fence posts 19, 20, 21, 22 of the side fences 15, 16, and a side fence main body holder 27 that holds the side fences 15, 16 at the lower part of the side fence main bodies 17, 18.

[0045] Therefore, in the bed 1 configured as described above, when the side rails 15, 16 that were attached to the side of the base 3 and used are removed and stored in the side rail storage space 25, one of the side rail supports 19, 20, 21, 22 of the side rails 15, 16 is held by the side rail support holder 26 and the lower part of the side rail main body 17, 18 is placed on the side rail main body holder 27, and the side rails 15, 16 can be easily stored and also easily removed.

[0046] In addition, the bed 1 is configured such that the side fence main body holder 27 has retaining grooves 32, 33 formed along the lower ends of the side fence main bodies 17, 18 to hold the lower ends of the side fence main bodies 17, 18.

[0047] Therefore, in the bed 1 configured as described above, the rattling of the side rails 15, 16 stored in the side rail storage space 25 can be reduced.

[0048] In addition, the bed 1 is configured such that the retaining grooves 32, 33 have upper end openings 34 formed therein that are wider than the thickness of the side fence bodies 17, 18.

[0049] Therefore, in the bed 1 configured as described above, when storing the side fences 15, 16 in the side fence storage space 25, there is a gap between the side fence main bodies 17, 18 and the upper end openings 34 of the retaining grooves 32, 33, and even if the side fence main bodies 17, 18 are slightly misaligned from the correct storage position, the side fence main bodies 17, 18 can be inserted into the retaining grooves 32, 33, making the work of storing the side fences 15, 16 even easier.
