[0010] The objective of suppressing damage caused by force acting on the main body of a board applied to a curved headboard or footboard is achieved by using a wooden board.
[0011] That is, the board (11) comprises a wooden main body (13) erected along the width direction on the longitudinal edge of the bed body (1a), and an attachment portion (15) for attaching to the bed body (1a) provided on the main body (13). The main body (13) is made by laminating two vertical veneers (21) having vertical grain directions along the erection direction between two horizontal veneers (23) having horizontal grain directions along the width direction, and the center portion in the width direction is curved so that it convex outward in the longitudinal direction.
[0012] The main body (13) may have three horizontal veneers (23) located on both sides and in the center in the stacking direction, and may be stacked so that two vertical veneers (21) are sandwiched between the central horizontal veneer (23) and the horizontal veneers (23) on both sides.
[0013] The main body (13) may be configured so that its curvature increases as it moves away from the bed body (1a) in the upright direction.
[0014] The attachment portion (15) may be integral with the main body portion (13) and may have the same laminated structure as the main body portion (13).
[0015] The mounting portion (15) consists of a pair of mounting pieces (15a, 15b) spaced apart in the width direction, and the board (11) may include mounting brackets (17) attached to the pair of mounting pieces (15a, 15b), respectively, and a cover (19) provided between the pair of mounting pieces (15a, 15b) in the width direction and attached to the pair of mounting pieces (15a, 15b).
[0016] The mounting bracket (17) may be fastened together with the mounting pieces (15a, 15b) to the cover (19).
[0017] The cover (19) may include a protrusion (39) that protrudes inward in the longitudinal direction from the main body (13) and covers the gap between the main body (13) and the bed body (1a). [Example]
[0018] FIG. 1 is a perspective view showing a bed to which a board according to a first embodiment of the present invention is applied.
[0019] The bed 1 is a nursing bed used in, for example, nursing homes, hospitals, etc. The bed 1 is configured by attaching a headboard 11a and a footboard 11b to a bed body 1a. The footboard 11b may be omitted.
[0020] The bed body 1a is supported on a support surface such as the floor via legs 3 so that a bed frame 5 can be raised and lowered in the vertical direction. A bottom 7 is attached to the bed frame 5, and a mattress 9 is placed on the bottom 7.
[0021] On both longitudinal sides of the bed body 1a, a headboard 11a and a footboard 11b, which are made up of the board 11 of this embodiment, are provided from the bed frame 5. The longitudinal direction and width direction refer to the longitudinal direction and width direction of the bed 1 in a plan view.
[0022] Fig. 2 is a perspective view showing the board 11 attached to the bed 1 of Fig. 1. Fig. 3 is a side view of the board 11 of Fig. 2, Fig. 4 is a plan view of the same, and Fig. 5 is a cross-sectional view taken along line VV of Fig. 4. Fig. 6 is a front view showing the main body 13 and attachment portion 15 of the board 11.
[0023] Since the headboard 11a and the footboard 11b of the board 11 have a common structure, only the footboard 11b will be described, and a description of the headboard 11a will be omitted.
[0024] The board 11 of this embodiment includes a main body 13 , a mounting portion 15 , a mounting bracket 17 , and a cover 19 .
[0025] The main body 13 is a curved wooden plate and stands upright along the width direction of the longitudinal edge of the bed 1. In this embodiment, the standing direction is the vertical direction. However, the standing direction may also be inclined relative to the vertical direction.
[0026] The main body 13 is curved so that the central portion in the width direction is convex outward in the longitudinal direction, and the overall curved shape is an arc. However, the curved shape of the main body 13 may be only a part, such as the central portion in the width direction. Note that the central portion in the width direction does not mean the exact center, but may be a portion displaced to one side or the other in the width direction from the center. The main body 13 has a gradually increasing curve in the upright direction as it moves away from the bed body 1a, i.e., upward.
[0027] Fig. 7 is a longitudinal cross-sectional view showing the laminated structure of the main body 13 and the mounting portion 15 of the board 11, and Fig. 8 is a transverse cross-sectional view of the same. The longitudinal cross-sectional view of Fig. 7 shows a cross-section along the vertical direction from the main body 13 to the mounting portion 15, and the transverse cross-sectional view of Fig. 8 shows a cross-section along the width direction of the main body 13. In both Fig. 7 and Fig. 8, hatching in the cross-section indicates the fiber direction.
[0028] The main body 13 is formed by laminating horizontal veneers 21 and vertical veneers 23. The horizontal veneers 21 are wooden veneers with fibers running horizontally along the width direction of the bed, and the vertical veneers 23 are wooden veneers with fibers running vertically along the direction in which the board 11 is erected.
[0029] The main body 13 of this embodiment is a 7-ply plywood made by laminating seven veneers 21, 23, with the horizontal veneers 21 positioned on both sides and in the center in the lamination direction, and two vertical veneers 23 sandwiched between the central horizontal veneer 21 and the horizontal veneers 21 on both sides.
[0030] Therefore, the main body 13 of this embodiment is configured by sharing a central horizontal veneer 21, and stacking two vertical veneers 23 on both sides of the central horizontal veneer 21 so that they are sandwiched between the two horizontal veneers 21. The main body 13 may also be a four-ply plywood made by stacking four veneers 21, 23. In this case, it is sufficient to simply stack two vertical veneers 23 between two horizontal veneers 21.
[0031] The horizontal veneers 21 and the vertical veneers 23 have the same material and thickness in the stacking direction, and only the fiber direction differs from each other. However, the horizontal veneers 21 and the vertical veneers 23 may also differ from each other in material and thickness in the stacking direction.
[0032] In this embodiment, the main body 13 has veneer 25 attached to the outside of the horizontal veneers 21 on both sides in the stacking direction. The veneer 25 is an extremely thin wooden sheet. This veneer 25 may be omitted or replaced with a resin film or the like.
[0033] The main body 13 is provided with an attachment portion 15 for attaching to the bed main body 1a side. The bed main body 1a side refers to the attachment destination of the board 11.
[0034] The mounting portion 15 of this embodiment is composed of a pair of mounting pieces 15a. The mounting pieces 15a are integrally formed on the lower edge of the main body portion 13 and are formed in the shape of a rectangular plate. The mounting pieces 15a are arranged on both sides with a gap between them in the width direction. The layered structure of the mounting portion 15 is the same as that of the main body portion 13.
[0035] The laminated structure of the mounting piece 15a may be different from that of the main body 13. The mounting piece 15 may also have a single mounting piece. The mounting piece 15 may also be a separate mounting piece instead of being an integral mounting piece with the main body 13.
[0036] The mounting brackets 17 are used for mounting to the bed body 1a, and are attached to the pair of mounting pieces 15a. The mounting brackets 17 are composed of a base portion 27 and an engagement portion 29. The base portion 27 is formed in a plate shape and is joined to the mounting pieces 15a in an overlapping state. The base portion 27 is joined to the mounting pieces 15a with bolts 31.
[0037] The engaging portion 29 includes a hook portion 33 and a locking portion 35. The hook portion 33 is engaged with an engaging protrusion 37 on the bed body 1a by being inserted into upper and lower hook grooves 33a and 33b. The locking portion 35 is provided so as to be rotatable relative to the engaging portion 29 between a locked position and an unlocked position.
[0038] The locking portion 35 in the locked position engages with the engaging protrusion 37 engaged in the upper hook groove 33a, and maintains the state in which the hook grooves 33a and 33b are engaged with the engaging protrusion 37. The locking portion 35 in the unlocked position can release the state in which the hook grooves 33a and 33b are engaged with the engaging protrusion 37. The locking portion 35 on the right side in Fig. 4 and Fig. 5 is in the unlocked position, and the locking portion 35 on the left side in Fig. 4 is in the locked position.
[0039] The cover 19 is a channel member made of resin or the like, and opens on the longitudinal side of the bed body 1a. The cover 19 is provided along the width direction of the body part 13 of the board 11. The cover 19 covers the part of the board 11 that is attached to the bed body 1a.
[0040] The cover 19 is fastened together with the mounting bracket 17 to the mounting piece 15a of the mounting portion 15. That is, a bolt 31 that connects the mounting bracket 17 to the mounting piece 15a is inserted through the mounting piece 15a and threaded into the female thread portion 19a of the cover 19.
[0041] This cover 19 prevents deformation of the main body 13 of the board 11 due to temperature and humidity, and maintains the positional relationship of the mounting brackets 17. As a result, it is possible to easily and reliably attach the board 11 to the bed body 1a using the mounting brackets 17 on both sides in the width direction.
[0042] In particular, since the cover 19 is fastened together with the mounting bracket 17 to the mounting piece 15a of the mounting portion 15, the positional relationship of the mounting bracket 17 can be reliably maintained.
[0043] The cover 19 of this embodiment has protrusions 39 that protrude inward in the longitudinal direction from the main body 13 of the board 11. The inward in the longitudinal direction refers to the inside of the bed 1, with the board 11 as the boundary. The locking parts 35 of the mounting bracket 17 are configured flush with both sides of the protrusions 39 in the width direction.
[0044] 9, the protrusion 39 covers the gap G between the main body 13 of the board 11 and the bed main body 1a (bed frame 5) in a plan view. This makes it possible to suppress wind from entering the gap G and to prevent feet from getting into the gap G.
[0045] In this embodiment, since the main body 13 of the board 11 is curved, even if the head or feet protrude from the mattress 9, they are less likely to hit the main body 13 of the board 11, but on the other hand, the gap G tends to become larger, and it is possible to cover the gap G by using the cover 19.
[0046] In this bed 1, when a longitudinal force acts on the main body 13 of the board 11, as shown by the arrows in Figures 3, 7, and 8, the force is dispersed by the curved shape with the center of the width direction convex. In other words, the force is dispersed in a direction along the board 11 and a direction perpendicular to the board 11, depending on the direction in which the force is applied and the inclination of the main body 13 of the board 11 at the part where the force is applied.
[0047] A force perpendicular to the board 11 acts to deflect the main body 13 in the plan view of Fig. 3. At this time, the deflection of the main body 13 of the board 11 is suppressed by the horizontal veneers 21 located on both sides and in the center in the stacking direction, as shown in Fig. 8. Furthermore, in the stacked structure of the main body 13, the horizontal veneers 21 and the vertical veneers 23 are paired to improve the overall rigidity, and deflection due to localized forces is suppressed.
[0048] As a result, a force perpendicular to the board 11 is likely to act between the main body portion 13 and the mounting portion 15 of the board 11 .
[0049] Between the main body portion 13 and the mounting portion 15, deflection is suppressed by two vertical veneers 23 sandwiched between the horizontal veneers 21 on both sides and in the center in the stacking direction. In this case, as shown in Figure 7, the vertical veneers 23 are stacked in greater numbers than the horizontal veneers 21, so deflection between the main body portion 13 and the mounting portion 15 can be reliably suppressed. Moreover, because the vertical veneers 23 are stacked in pairs, deflection between the main body portion 13 and the mounting portion 15 can be more reliably suppressed.
[0050] Therefore, in the board 11 applied to the curved headboard 11a or footboard 11b, damage caused by a force acting on the main body portion 13 can be suppressed.
[0051] In this embodiment, the curved shape of the board 11 distributes the force, and the deflection of the main body 13 of the board 11 itself, which is relatively unlikely to deflect due to localized force, is suppressed by the horizontal veneers 21, which have a smaller number of layers, while the deflection between the main body 13 of the board 11 and the mounting part 15, which is relatively likely to deflect even due to localized force, is suppressed by the vertical veneers 23, which have a larger number of layers. As a result, the deflection and damage of the entire board 11 can be suppressed, improving durability.
[0052] Even if the mounting portion 15 is separate from the main body portion 13 and is connected to the main body portion 13 with fasteners such as bolts, damage to the connection portion can be suppressed by the laminated structure of the main body portion 13. [Explanation of symbols]
