Description

bed

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

[0002] Conventionally, beds have been provided with a support platform on top of the base for a reclining person (a person lying on the bed in a supine, lateral, prone, or other position) to lie on, and side rails are detachably attached to the sides of the base (to the sides of the support platform) to prevent the reclining person, bedding, etc. from falling off the support platform.

[0003] This side fence has a pair of side fence posts formed at the bottom of the side fence body facing downward, 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) at the end of the base and the receiving base so that the removed side rail can be stored in the bed when it is removed from the base.

[0005] Japanese Patent Application Laid-Open No. 2006-55529

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

[0007] When the side fence that has been attached to the side of the base and is to be removed and stored in the side fence storage space, the pair of side fence supports formed on the side fence are inserted into the retaining holes formed in the pair of holders, respectively, to store the side fence in the side fence storage space.

[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 a margin between the diameter of the side fence posts and the diameter of the retaining holes to prevent rattle, so it is necessary to make the diameter of the retaining holes larger than the diameter of the side fence posts, which causes the side fence posts to rattle against the holders, causing discomfort to the bed occupant.

[0009] Furthermore, in conventional beds, when a pair of holders 38, 38 are arranged so that the regular-sized side rail 36 is at 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-sized side rail 39 that is longer than the regular-sized 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. One way to solve this problem is to shift the position of the pair of holders 38, 38 so that the long side rail 39 is centered within the width of the board 37. However, due to various reasons that make it impossible to change the spacing between the pair of side rail supports 40, 40 or the spacing between the left and right frames 41, 41 that support the bed base, as shown in Figure 8(c), one of the holders 38 cannot be attached because it will be in a position that interferes with the bed frame 41 or the bracket 42 of the board 37, and this creates the problem that the long side rail 39 cannot be centered within the width of the board 37.

[0010] Therefore, in the present invention according to claim 1, a support platform for a person to lie on is provided on the top of the base, and a side fence with a pair of side fence posts formed at the bottom of the side fence main body is detachably provided on the left and / or right side of the base, 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 at the bottom of the side fence main body.

[0011] Furthermore, in the present invention according to claim 2, in the present invention according to claim 1, a retaining groove is formed in the side fence main body holder 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 that is wider than the thickness of the side fence body.

[0013] The present invention provides the following effects.

[0014] In other words, in this invention, a bed is provided on top of the base where a support platform for a reclining person to lie on is provided, and side fences with a pair of side fence posts formed at the bottom of the side fence main body are detachably attached to the left and / or right sides of the base, and a side fence storage space for storing side fences removed from the base is provided between a board attached to 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 at 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, it is sufficient to hold one of the side fence posts with the side fence post holder and place the bottom of the side fence main body on the side fence main body holder, and the side fence can be easily stored and removed.

[0015] Furthermore, in the present invention, the side fence is held in place 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, if a retaining groove that holds the lower end of the side fence body along the lower end of the side fence body is formed in the side fence body holder, the rattling 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 end opening that is wider than the thickness of the side fence body, when the side fence is stored in the side fence storage space, there is a gap between the side fence body and the upper end opening of the retaining groove, and the side fence body can be inserted into the retaining groove even if it is slightly deviated from its normal storage position, making the work of storing the side fence even easier.

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

[0020] 1 to 3, bed 1 has a support 2 for supporting the body of a person lying down attached to the top of a base 3. For convenience, the foot side (right side in FIG. 1) of a person lying down on bed 1 will be referred to as the front side, and the head side (left side in FIG. 1) will be referred to as the rear side.

[0021] The bed 2 is in the form of a rectangular flat plate and is attached to the top of the base 3. 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 one another in the front and rear. 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 one another in the left and right. The base 3 may be configured as a lift-type bed that raises and lowers the receiving platform 2, or may be provided with casters to form a mobile bed.

[0023] The base 3 also has horizontally elongated rectangular boards (footboard 10 and headboard 11) detachably attached to the left and right frames 6 and 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, each protruding outward at a distance from the front and rear, and side rails 15, 15, 16, 16 attached to each of the pair of front and rear supports 13, 14 in a detachable manner.

[0025] The long-size side rails 16 are longer in length from front to back than the regular-size side rails 15, and when the short (regular-size) side rails 15 are attached to the base 3 side by side (on the left side of the base 3 in Figure 1), a gap of sufficient width is formed between the front and rear side rails 15, 15 to allow a recumbent person to get on and off the bed 1. On the other hand, when the long (long-size) side rails 16 are attached to the base 3 side by side (on the right side of the base 3 in Figure 1), almost no gap is formed 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 body 17 of the regular-size side fence 15 is shorter than the length of the side fence 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 attached and detached freely 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 symmetrical shape, 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 the overhang length on one side of the side fence main body 18 is the same as the overhang length of the regular-size side fence main body 17, and the overhang length on the other side of the side fence main body 18 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 above downward 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 while they are attached.

[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 the side rail storage space 25 formed between the end of the support base 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 pair of side fence posts 19, 20, 21, 22 provided on the side fences 15, 16 (20, 22) and a side fence main body holder 27 for holding the side fences 15, 16 at the bottom 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 boards (footboard 10, headboard 11) instead of the base 3.

[0031] A single 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] As shown in Figure 4, the side fence post holder 26 has a hollow rectangular box shape with through holes 28, 28 formed on the left and right sides to allow the front frame 8 to pass through, and two through-holes 29, 30 with circular cross-sections formed on the top. 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 allowing the front frame 8 to pass through 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 holding holes 29, 30, so that the side fence posts 19, 20, 21, 22 of the side fences 15, 16 are held by the holding holes 29, 30.

[0035] As shown in Figure 5, the side fence main body holder 27 has a mounting portion 31 at the bottom for mounting to the front frame 8, and two holding grooves 32, 33 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, so that the side fence main body 17, 18 of the side fence 15, 16 is held by the holding groove 32, 33.

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

[0039] Furthermore, in the side fence main body holder 27, the upper end opening 34 is wider than the thickness of the lower part of the side fence main bodies 17, 18, so the position of the stored side fences 15, 16 can 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 holding 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 holder 26, it is possible to reduce the rattling of the side fences 15, 16 stored in the side fence storage space 25.

[0041] The mounting positions of the side fence support holders 26 and the side fence main body holders 27 in the side fence storage space 25 may be, for example, as shown in Figure 6(a), such that when a long-size side fence 16 is stored in the side fence storage space 25, the long-size side fences 16 are 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 Figure 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 overhangs the same amount 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 reduced, and storing the long-size side fence 16 has almost no effect on the installation space of the bed 1 and does not interfere with the movements of the user, caregiver, etc. around the bed 1.

[0042] Furthermore, the mounting positions of the side fence post holders 26 and the side fence main body holders 27 in the side fence storage space 25 may be, for example, as shown in Figure 7(a), so that 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 beyond the footboard 10 in a front view, and only the other side of the long-size side fence 16 protrudes beyond the footboard 10. In this case, as shown in Figure 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. This is suitable for installing one side of the footboard 10 against a room wall without any gaps.

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

[0044] The side fences 15, 16 stored in the side fence storage space 25 are held in place 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 body holder 27 that holds the side fences 15, 16 at the bottom of the side fence bodies 17, 18.

[0045] Therefore, in the bed 1 configured as described above, when removing the side fences 15, 16 that have been attached to the sides of the base 3 and storing them in the side fence storage space 25, it is sufficient to hold one of the side fence posts 19, 20, 21, 22 of the side fences 15, 16 with the side fence post holder 26 and place the lower part of the side fence main body 17, 18 on the side fence main body holder 27, allowing the side fences 15, 16 to be easily stored and also removed easily.

[0046] In addition, the bed 1 is configured such that the side fence main body holder 27 has holding 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 rattle 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 deviated from their normal storage positions, 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.
