[Diagram 2] FIG. 2 is an enlarged side cross-sectional view showing the safety mechanism (ON position). [Diagram 3] FIG. [Figure 4] FIG. [Diagram 5] FIG. 4 is an enlarged side cross-sectional view showing the safety mechanism (OFF position). [Figure 6] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, a specific configuration of the bedside table according to the present invention will be described with reference to the drawings.

[0016] As shown in FIG. 1, the bedside table 1 has a lower end of a support column 3 that extends vertically up and down attached to the rear of a base 2, a support case 4 attached to the upper end of the support column 3, and a top plate 5 that extends horizontally back and forth attached to the upper part of the support case 4. The support column 3 has a hollow outer support column 6 that has a rectangular cross section attached to the rear upper side of the base 2, and a hollow inner support column 7 that has a rectangular cross section attached to the support case 4 on the rear lower side of the top plate 5 is inserted into the hollow part of the support column 3 at a distance so that the support column 3 can move up and down. Casters are attached to the base 2 to allow the bedside table 1 to move smoothly, and a locking function is provided on the casters on the support column 3 side so that the bedside table 1 can be stationary. The bedside table 1 has a top plate 5 cantilevered on the upper end of one support column 3, but the bedside table 1 is not limited to this, and the top plate 5 may be provided between the upper ends of multiple (for example, two) support columns 3. Furthermore, the support pillars 3 have the inner support pillars 7 provided on the tabletop 5 side and the outer support pillars 6 provided on the base 2 side, but this is not limited to this, and the inner support pillars 7 may be provided on the base 2 side and the outer support pillars 6 on the tabletop 5 side.

[0017] The bedside table 1 is provided with a lifting means 8 for raising and lowering the top board 5, and also with a safety mechanism 9 for forcibly raising the top board 5 by the lifting means 8 when an upward force acts on the top board 5 from below.

[0018] As shown in FIGS. 2 and 3, the lifting means 8 accommodates a telescopic cylinder 10 that extends and retracts up and down in the hollow portion of the support column 3, and accommodates an operating lever 11 inside the support case 4.

[0019] The lower end of the cylinder section 12 of the telescopic cylinder 10 is attached to the upper rear side of the base 2, while the bottom plate 14 of the support case 4 is placed on the upper end of the rod section 13 via a spacer 15. The spacer 15 is attached to the upper end of the rod section 13, with the upper small diameter section 16 inserted into an insertion hole 17 formed in the bottom plate 14 of the support case 4, and the bottom plate 14 of the support case 4 is placed on the lower large diameter section 18, which is larger in diameter than the small diameter section 16.

[0020] The operating lever 11 is attached to the rear side plate 19 of the support case 4 via a shaft 20 and a bracket 21 so as to be freely swingable up and down. A lever portion 22 on the rear side of the shaft 20 protrudes outward from the support case 4, while an operating portion 23 on the front side of the shaft 20 abuts from above against a protrusion 24 formed on the upper end of the rod portion 13 of the telescopic cylinder 10.

[0021] When the lever portion 22 of the operating lever 11 of the lifting means 8 is lifted upward, the actuating portion 23 of the operating lever 11 presses the protrusion 24 of the rod portion 13 of the telescopic cylinder 10 downward, unlocking the telescopic cylinder 10. This causes the rod portion 13 of the telescopic cylinder 10 to advance upward relative to the cylinder portion 12, lifting the support case 4 upward and raising the top plate 5. When a downward force is applied to the top plate 5 with the telescopic cylinder 10 unlocked, the top plate 5 can be lowered.

[0022] The safety mechanism 9 has a lower part 26, which extends from the front to the rear of an L-shaped plate 25 in a side view, attached to the upper end of the telescopic cylinder 10, and has an operating part 23 of the operating lever 11 inserted into a through hole 28 extending vertically formed in an upper part 27 extending vertically of the plate 25. Here, the operating lever 11 is in a state in which the tip lower part of the operating part 23 abuts against the upper end of the protrusion 24, and the middle upper part of the operating part 23 abuts against the opening upper end of the through hole 28.

[0023] The plate 25 has a lower portion 26 that extends forward and backward in parallel to the bottom plate 14 of the support case 4 at a fixed interval (predetermined vertical width H) from the bottom plate 14, and is fixed to the upper end of the telescopic cylinder 10 by clamping the lower portion 26 between the small diameter portion 16 of the spacer 15 and a nut 29. In addition, the plate 25 has a spring 31 provided on a holder 30 attached to the bottom plate 14 of the support case 4 in contact with the upper surface of the lower portion 26.

[0024] As shown in FIG. 4, when an upward force is applied to the tabletop 5 from below, the tabletop 5 and the support case 4 rise a vertical width H without changing the vertical position of the plate 25, and accordingly, the middle upper part of the actuating part 23 of the operating lever 11 is pressed downward by the upper end of the opening of the through-hole 28, causing the operating lever 11 to rotate upward and the lower tip part of the actuating part 23 to press downward the protrusion 24 of the rod part 13 of the telescopic cylinder 10, thereby unlocking the telescopic cylinder 10 and forcibly lifting the tabletop 5.

[0025] As shown in Figures 2 to 6, this safety mechanism 9 is provided with a changeover switch 32 that can be changed between an ON position in which the safety mechanism 9 is activated (the safety mechanism 9 is activated) and an OFF position in which the safety mechanism 9 is not activated (the safety mechanism 9 is not activated).

[0026] The changeover switch 32 has an axis 34 rotatably inserted through a through hole 33 formed in the bottom plate 14 of the support case 4, an operating unit 35 attached to the lower side of the axis 34 (lower side of the bottom plate 14), and a switching unit 36 ​​attached to the upper side of the axis 34 (upper side of the bottom plate 14).By rotating the operating unit 35 from outside the support case 4, the switching unit 36 ​​inside the support case 4 can be rotated.

[0027] The operation portion 35 is formed with a knob 37 that protrudes linearly downward.

[0028] The switching portion 36 has at one end a switching piece 38 of approximately the same height as the vertical width H that can be inserted between the lower surface of the lower portion 26 of the plate 25 and the upper surface of the bottom plate 14 of the support case 4, and at the other end a locking body 39 is formed via an elastically deformable support body 40. At predetermined positions (two places) of the bottom plate 14 of the support case 4, through-holes 41 and 42 into which the locking body 39 engage are formed.

[0029] As shown in Figs. 2 and 3, the change-over switch 32 is placed in the ON position by retracting the switching piece 38 from the vertical width H between the underside of the lower part 26 of the plate 25 and the upper surface of the bottom plate 14 of the support case 4. When an upward force is applied to the top plate 5 from below as shown in Fig. 4, the top plate 5 rises, and in response, the operating part 23 of the operating lever 11 presses the protrusion 24 of the rod part 13 of the telescopic cylinder 10 to unlock the telescopic cylinder 10 and activate the safety mechanism 9, which forcibly raises the top plate 5.

[0030] In addition, as shown in Figures 5 and 6, the change-over switch 32 is placed in the OFF position by inserting the switching piece 38 into the vertical width H between the underside of the lower part 26 of the plate 25 and the upper surface of the bottom plate 14 of the support case 4, and even if an upward force acts on the top plate 5 from below, the switching piece 38 prevents the top plate 5 from rising, so that the safety mechanism 9 is not activated.

[0031] The position of the changeover switch 32 can be changed from the ON position to the OFF position and from the OFF position to the ON position by rotating the operating part 35. In the ON position or the OFF position, the locking body 39 engages with one of the engagement holes 41, 42, and the switch is maintained in the ON position or the OFF position.

[0032] As described above, the bedside table 1 is placed in front of the person lying down from the side of the bed, and the top plate 5 is raised and lowered by the lifting means 8, and is provided with a safety mechanism 9 that forcibly raises the top plate 5 by the lifting means 8 if an upward force is applied to the top plate 5.

[0033] The bedside table 1 is provided with a changeover switch 32 that can change the position between an ON position in which the safety mechanism 9 is activated and an OFF position in which the safety mechanism 9 is not activated.

[0034] Therefore, in the bedside table 1 configured as described above, when in use, the change-over switch 32 can be set to the ON position to activate the safety mechanism 9, ensuring safety, and when moving (transporting) the bedside table 1, the change-over switch 32 can be set to the OFF position to prevent the safety mechanism 9 from being activated inadvertently, thereby enabling the bedside table 1 to be moved (transported) smoothly.

[0035] In addition, the bedside table 1 is configured so that the top plate 5 can be raised and lowered by a predetermined vertical width H relative to the lifting means 8, and a safety mechanism 9 is configured so that the top plate 5 is forcibly raised by the lifting means 8 when the top plate 5 rises by the vertical width H relative to the lifting means 8. The bedside table 1 is configured to be able to change its position between an OFF position in which the top plate 5 is prevented from rising by the vertical width H and the safety mechanism 9 is not activated by inserting the switching piece 38 of the changeover switch 32 into the gap of the vertical width H, and an ON position in which the top plate 5 can be raised by the vertical width H and the safety mechanism 9 is activated by retracting the switching piece 38 from the gap of the predetermined vertical width H.

[0036] Therefore, in the bedside table 1 having the above configuration, the changeover switch 32 can be easily and reliably changed between the ON position and the OFF position.

[0037] Further, the bedside table 1 is configured so that the changeover switch 32 is locked in the ON position and the OFF position.

[0038] Therefore, in the bedside table 1 having the above configuration, the changeover switch 32 can be held in the ON position or the OFF position, preventing the changeover switch 32 from accidentally changing its position, and enabling the changeover switch 32 to easily and reliably change its position between the ON position and the OFF position.

[0039] In addition, the bedside table is provided with a detachable stopper in the vertical width H, and the safety mechanism 9 can be switched ON / OFF by removing the stopper attached at the time of delivery after delivery, but this is not preferable because it is difficult to attach the stopper again after the stopper is removed, and there is a risk of losing the stopper. For this reason, the bedside table 1 is provided with a changeover switch 32 that can change between the ON position and the OFF position in a manner that makes it impossible to remove it from the bedside table 1. Here, in the bedside table 1, the changeover piece 38 of the changeover switch 32 is configured to be inserted or retracted in the vertical width H, but this is not limited to this, and the changeover switch 32 provided in the bedside table 1 may be configured to switch the safety mechanism 9 ON / OFF (for example, by rotating, sliding, or pressing the changeover piece 38). In addition, the changeover switch 32 may be provided in the bedside table 1 regardless of whether it is in the ON position or the OFF position, and the position at which it is provided (for example, the lower side, rear side, left or right side of the support case 4, etc.) is not limited.
