Mode for Carrying Out the Invention

[0018] Hereinafter, the specific configuration of the board for a bed according to the present invention will be described with reference to the drawings.

[0019] As shown in FIG. 1, the bed 1 has a receiving base 3 attached to the upper part of the base 2, and a bed board (head board 4) attached to the rear end of the base 2 (the head side of the person lying down on the receiving base 3), and a bed board (foot board 5) attached to the front end of the base 2 (the foot side of the person lying down on the receiving base 3).

[0020] As shown in FIGS. 1 to 4, the head board 4 has a housing recess 7 formed in a concave shape from the outside to the inside of the bed 1 at the upper center of the rear side (the outside of the bed 1) of the rectangular plate-shaped board body 6. A mounting table 8 for placing small items is attached to the upper end of the housing recess 7 so as to be rotatable up and down (openable and closable) via a pair of left and right hinge mechanisms 9, 9. A gap is provided between the inner circumference of the housing recess 7 and the outer circumference of the mounting table 8 so as not to hinder the opening and closing of the mounting table 8. Further, a finger insertion recess 10 for inserting a finger is formed at the center of the lower end of the housing recess 7, and a finger hook recess 11 for hanging a finger is formed at the center of the tip (lower end) of the mounting table 8 to facilitate the opening and closing operation of the mounting table 8.

[0021] Thereby, the head board 4 can be changed in posture between a storage posture in which the mounting table 8 is closed vertically and stored in the housing recess 7 when the mounting table 8 is not in use, and a use posture in which the mounting table 8 is opened horizontally and protrudes forward (rearward of the bed 1) from the board body 6 when the mounting table 8 is in use.

[0022] The mounting table 8 forms a bulging portion 12 that bulges upward in the use posture at the peripheral edge of the upper surface, and hinge mechanisms 9, 9 are disposed (accommodated) inside the bulging portion 12.

[0023] One end of the hinge mechanism 9 is fixed to the front surface of the housing recess 7 of the board body 6 by a fixed bracket 13, while a movable bracket 14 is attached to the back surface (lower surface) of the mounting table 8. The base end (upper end) of the movable bracket 14 is rotatably attached to the base end (upper end) of the fixed bracket 13 via a rotating shaft 15. The fixed brackets 13 of the left and right hinge mechanisms 9, 9 are connected by a reinforcing plate 16. The deflection of the board body 6 can be reduced by this reinforcing plate 16.

[0024] Also, in the hinge mechanism 9, an operation lever 17 is provided movably along the movable bracket 14 (mounting table 8) inside the movable bracket 14. A spring 20 is provided between a holding piece 18 formed by bending at an intermediate portion of the movable bracket 14 and a holding hole 19 formed by punching at an intermediate portion of the operation lever 17. The operation lever 17 is biased toward the rotating shaft 15 by the elastic force of the spring 20. An engaging piece 21 for hanging a finger is formed by bending obliquely at the lower end of the operation lever 17.

[0025] This hinge mechanism 9 is provided with a posture holding means for holding the mounting table 8 in the accommodation posture and the use posture.

[0026] That is, the hinge mechanism 9 is formed with a right-angled upper engagement notch 22 and an obtuse-angled lower engagement notch 23 at the base end (upper end) of the fixed bracket 13, spaced vertically apart and facing in the rotational direction. On the other hand, the hinge mechanism 9 attaches an engagement body 24 to the tip (upper end) of the operation lever 17, and inserts the left and right ends of the engagement body 24 through the long-hole-shaped guide hole 25 formed in the movable bracket 14, so that by moving the operation lever 17 (mounting table 8) along the movable bracket 14, the engagement body 24 moves forward and backward toward the fixed bracket 13 according to the guide hole 25. Thus, the hinge mechanism 9 rotates the mounting table 8 so that the engagement body 24 of the operation lever 17 provided on the movable bracket 14 engages with the upper engagement notch 22 or the lower engagement notch 23 of the fixed bracket 13 by the biasing force of the spring 20, and holds the mounting table 8 in the storage position or the use position.

[0027] And as shown in Fig. 5(a), in the storage position where the mounting table 8 is stored in the storage recess 7, the hinge mechanism 9 causes the engagement body 24 of the operation lever 17 provided on the movable bracket 14 to engage with the lower engagement notch 23 of the fixed bracket 13 by the biasing force of the spring 20, and holds the storage position of the mounting table 8 so that the mounting table 8 does not accidentally open or close. Note that as the posture holding means, a convex portion (or concave portion) may be formed on the mounting table 8, and a concave portion (or convex portion) may be formed in the storage recess 7, and the convex portion (or concave portion) of the mounting table 8 and the concave portion (or convex portion) of the storage recess 7 may be fitted together in the storage position to hold the storage position of the mounting table 8 and prevent the mounting table 8 from accidentally opening.

[0028] When the mounting table 8 is rotated forward from this storage position, as shown in Fig. 5(b), the engaging body 24 of the operation lever 17 gradually retracts along the inclined surface of the lower engaging notch 23 of the fixed bracket 13 against the biasing force of the spring 20. Then, as shown in Fig. 5(c), the engaging body 24 of the operation lever 17 disengages from the lower engaging notch 23 of the fixed bracket 13. In this state, when the rotation operation of the mounting table 8 is stopped, the mounting table 8 rotates downward due to its own gravity and then, due to the biasing force of the spring 20, the engaging body 24 gradually advances along the inclined surface of the lower engaging notch 23 so that the mounting table 8 automatically returns to the storage position.

[0029] When the mounting table 8 is further rotated forward, as shown in Fig. 5(d), the engaging body 24 of the operation lever 17 engages with the upper engaging notch 22 of the fixed bracket 13 by the biasing force of the spring 20 to hold the mounting table 8 in the use position where it projects forward from the board body 6.

[0030] In this use position, when the operation lever 17 is retracted against the biasing force of the spring 20 using the finger hook piece 21, as shown in Fig. 5(e), the engagement between the engaging body 24 of the operation lever 17 and the upper engaging notch 22 of the fixed bracket 13 is released, and by simply rotating the mounting table 8 downward, the mounting table 8 can be put into the storage position as shown in the order of Figs. 5(c), (b), and (a). Note that the left and right operation levers 17 may be connected so that the left and right hinge mechanisms 9 can be operated simultaneously.

[0031] Note that a protruding portion 26 protruding forward is formed at the upper end of the board body 6, and a recessed portion 27 recessed rearward is formed below the protruding portion 26. In the storage position, the surface of the mounting table 8 does not project forward beyond the protruding portion 26 of the board body 6 in plan view, and a gap sufficient not to hinder the opening and closing of the mounting table 8 is provided between the upper end of the mounting table 8 and the inside of the protruding portion 26 so that the upper end portion of the mounting table 8 can rotate smoothly inside the recessed portion 27 when changing the posture between the storage position and the use position.

[0032] The board for bed (headboard 4) according to the present invention is configured as described above. However, it is not limited to the case where the mounting table 8 is provided on the front surface of the headboard 4, and the mounting table 8 may be provided on the back surface of the headboard 4 or the front or back surface of the footboard 5. Further, in the above-mentioned board for bed (headboard 4), the mounting table 8 is attached to the upper end of the storage recess 7 so as to be openable and closable via the hinge mechanism 9. However, it is not limited to this. As shown in FIGS. 6(a) and 6(b), the mounting table 8 may be attached to the lower end of the storage recess 7 so as to be openable and closable via the hinge 28. Further, as shown in FIGS. 6(c) and 6(d), the mounting table 8 may be attached to the upper end of the storage recess 7 so as to be openable and closable, and the mounting table 8 may be supported by a support body 29 that is rotatable up and down from below. Furthermore, as shown in FIGS. 6(e) and 6(f), the mounting table 8 may be supported by a support body 30 that is openable and closable left and right from below.

[0033] As described above, the board for bed (headboard 4) is configured such that a mounting table 8 for placing small items is provided on the board main body 6 so as to be openable and closable, and the mounting table 8 can be changed between a storage posture in which the mounting table 8 is closed and stored in the storage recess 7 of the board main body 6 and a use posture in which the mounting table 8 is opened and protruded from the board main body 6.

[0034] Therefore, in the board for bed (headboard 4) having the above configuration, the mounting table 8 can be used as needed without increasing the thickness of the board for bed (headboard 4), and it is possible to prevent people, objects, etc. from being caught on the mounting table 8 around the bed 1.

[0035] Further, the board for bed (headboard 4) is configured such that the mounting table 8 is attached to the board main body 6 via a hinge mechanism 9, and the hinge mechanism 9 is provided with a posture holding means for holding the mounting table 8 in a storage posture or a use posture.

[0036] Therefore, in the board for bed (headboard 4) having the above configuration, it is possible to prevent the mounting table 8 from inadvertently opening and closing during use (use posture) or when not in use (storage posture).

[0037] In addition, the above bed board (head board 4) is configured such that a bulging portion 12 bulging upward in the use posture is formed at the periphery of the mounting table 8, and a hinge mechanism 9 is disposed inside the bulging portion 12.

[0038] Therefore, with the bed board (head board 4) having the above configuration, it is possible to prevent small items from falling from the mounting table 8, and it is possible to suppress the thickness of the bed board (head board 4) provided with the mounting table 8 so as to be openable and closable.
