Summary of the Invention

Problems to be Solved by the Invention

[0006] However, in the conventional bedside table described above, the casters on the base and the operating lever on the tabletop are connected by a wire that is divided into multiple parts (for example, a wire that is divided into two parts: one directly connected to the casters and another directly connected to the operating lever). This allows the wire to be housed inside a vertically extendable support column, and the casters on the base and the operating lever on the tabletop are connected by the wire.

[0007] Therefore, with conventional bedside tables, assembly and disassembly require connecting and separating multiple wires, which could make assembly, disassembly, and maintenance of the bedside table difficult. [Means for solving the problem]

[0008] Therefore, in the present invention according to claim 1, a bedside table is provided in which a top plate is mounted on a base so as to be able to move up and down via a vertically extendable support column, and casters are mounted on the base so as to be able to roll, wherein a lifting support column of the support column connected to the top plate is mounted so as to be able to move up and down relative to a fixed support column of the support column connected to the base, and an operating lever is connected to the caster via a wire, and the caster can be locked or unlocked by slackening the wire with the operating lever, the operating lever is provided in a position that can be operated by hand, and the operating lever and the caster are connected by a single wire.

[0009] Furthermore, in the present invention according to claim 2, the operating lever and the caster are connected by a single wire, and the support column, top plate, and base can be separated without dividing the wire.

[0010] Furthermore, in the present invention according to claim 3, the operating lever and the caster are connected by a single wire, so that the distance between the operating lever and the caster does not change even when the top plate is raised or lowered.

[0011] Furthermore, in the present invention according to claim 4, the operating lever is provided on the fixed support column of the support column, and the operating lever and the caster are connected by a single wire.

[0012] Furthermore, in the present invention according to claim 5, the operating unit housing the operating lever and wire is mounted on the outside of the fixed support column of the support column, in accordance with any of the present inventions according to claims 1 to 4.

[0013] Furthermore, in the present invention according to claim 6, the operating unit is provided on the base so as to be able to be raised and lowered, and the operating unit can be changed between a mounting position in which the operating unit is upright relative to the base and attached to the fixed support column of the support column, and a storage position in which the operating unit is reclined relative to the base and housed along the base.

[0014] Furthermore, in the present invention according to claim 7, the bedside table can be assembled by connecting the divided support column, top plate, and base portion as they are, in the present invention according to claim 2. [Effects of the Invention]

[0015] Furthermore, the present invention provides the following effects.

[0016] In other words, in the present invention, a bedside table is provided in which a top plate is mounted on a base so as to be able to move up and down via a vertically extendable support column, and casters are mounted on the base so as to be able to roll. The lifting support column of the support column connected to the top plate is mounted so as to be able to move up and down relative to the fixed support column of the support column connected to the base, and an operating lever is connected to the caster via a wire, so that the caster can be locked or unlocked by loosening the wire with the operating lever, and the operating lever is provided in a position that can be operated by hand, and the operating lever and the caster are connected by a single wire, so that it is not necessary to connect or disconnect wires when assembling or disassembling the bedside table, thereby improving the workability of assembling, disassembling and maintaining the bedside table.

[0017] In particular, if the bedside table is designed to be separable into a support column, a tabletop, and a base, it can be separated (disassembled) into these parts for packaging and transport, and then assembled when it is time to set it up.

[0018] Furthermore, if the distance between the operating lever and the casters does not change even when the tabletop is raised or lowered, it becomes unnecessary to provide space for the wire to deform as the tabletop is raised or lowered (the support column extends or retracts), allowing for a smaller bedside table.

[0019] Furthermore, if the operating lever is installed on the fixed support column of the support column, it becomes unnecessary to house the wire in the lifting support column or the top plate. This also eliminates the need to provide space for the wire to deform as the top plate is raised or lowered (the support column extends or retracts), allowing for a smaller bedside table.

[0020] Furthermore, if the operating unit housing the operating lever and wire is mounted on the outside of the fixed support column of the support column, the bedside table can be assembled without performing tasks such as connecting wires, thereby improving the workability of assembling, disassembling, and maintaining the bedside table.

[0021] Furthermore, if the operating unit is provided on the base so as to be foldable, and its position can be changed between an upright position where the operating unit is attached to the fixed support column of the support column and an enclosed position where the operating unit is folded down relative to the base and housed along the base, then the bedside table can be assembled without the need for wire connection work by easily attaching the operating unit to the support column in the upright position, and the table can be easily transported by separating the top plate, support column, base, and operating unit into the enclosed position.

[0022] Also, when the divided support column part, top plate part, and pedestal part are directly connected to enable the assembly of the bedside table, the bedside table can be easily and quickly assembled without adding other members or the like.

Mode for Carrying Out the Invention

[0024] Hereinafter, the specific configuration of the bedside table according to the present invention will be described with reference to the drawings.

[0025] As shown in FIG. 1, the bedside table 1 is provided with a top plate part 3 that can be raised and lowered with respect to a pedestal part 4 via a vertically expandable and contractible support column part 2.

[0026] The support column part 2 is provided with a vertically extending rectangular cylindrical (hollow) lifting column 6 connected to the top plate part 3 so as to be able to move up and down with respect to a vertically extending rectangular cylindrical (hollow) fixed column 5 whose lower end is connected to the pedestal part 4.

[0027] In this support column part 2, the outer shape of the fixed column 5 is made larger than the outer shape of the lifting column 6, and the base end side (lower side) of the lifting column 6 is accommodated inside the fixed column 5, and the tip (upper end) of the lifting column 6 protrudes from the tip (upper end) of the fixed column 5. In addition, inside the support column part 2, a lifting mechanism (not shown) for moving the lifting column 6 up and down with respect to the fixed column 5 to expand and contract the support column part 2 vertically is accommodated.

[0028] It should be noted that in the original text, there is a misspelling in the tag , which should be . The above translation has been corrected accordingly.Furthermore, the support column 2 is detachably attached to the front upper part of the base portion 4 by attaching the base end of the fixed support column 5, and the tip of the lifting support column 6 is detachably attached to the front lower part of the top plate portion 3.

[0029] As a result, the bedside table 1 can be separated (disassembled) into the support column 2, the tabletop 3, and the base 4 for packaging and transport, and then assembled when it is time to set it up.

[0030] The top plate section 3 has the lower part of a hollow box-shaped support case 7 detachably attached to the tip (upper end) of the lifting support column 6, and a rectangular plate-shaped top plate 8 that extends forward and backward is attached to the upper part of the support case 7.

[0031] The support case 7 houses an operating mechanism (not shown) for operating the lifting mechanism of the support column 2, and has a lever 9 protruding from its front for operating the operating mechanism. When the lever 9 is pulled upward, the lock on the lifting mechanism is released, and the top plate 8 can be raised. Alternatively, the top plate 8 can be lowered by pushing it downward. When the lever 9 is released, the lifting mechanism is locked.

[0032] The base section 4 has the central part of the front leg body 11, which extends left and right, attached to the front end of the base 10, which extends front and back, and the central part of the rear leg body 12, which extends left and right, attached to the rear end of the base 10.

[0033] The base 10 has the fixed support column 5 of the support column section 2 detachably attached to its front upper part.

[0034] The front leg body 11 has support members 13 and 14 attached to its left and right ends, and the upper part of a caster 15 (16) is attached to the lower part of each support member 13 (14) so ​​as to be able to rotate horizontally. These casters 15 and 16 are connected to wires 17 and 18, and by loosening (relaxing or pulling) the wires 17 and 18, the rolling wheels 19 and 20 can be stopped (locked) or made able to roll on the floor (unlocked), thus forming a wire lock type. The front leg body 11 and support members 13 and 14 are detachably covered with a cover 21.

[0035] The rear leg 12 has support members 22 and 23 attached to its left and right ends, and the upper part of a caster 24 (25) is attached to the lower part of each support member 22 (23) so as to be able to rotate horizontally. The rear leg 12 and support members 22 and 23 are detachably covered with a cover 26.

[0036] As shown in Figures 2 to 4, an operating unit 27 for locking and unlocking wire-lock type casters 15 and 16 is foldably mounted on the upper rear center of the front leg 11 of this base 4.

[0037] The operating unit 27 has its base end (lower end) of an open, vertically extending case 28 attached to a support 29 provided on the upper central side of the front leg 11 via pivot shafts 30, 30 so as to be able to rotate back and forth.

[0038] As a result, the operating unit 27 can be positioned to stand upright relative to the base 4 (extended vertically) and detachably attached to the front side of the fixed support column 5 of the support column 2 (as shown by solid lines in Figures 3 and 4), and to stow position (as shown by dashed lines in Figures 3 and 4) where the operating unit 27 can be laid down relative to the base 4 (extended front and back) and housed horizontally along the base 4.

[0039] Furthermore, the operating unit 27 has an operating mechanism 31 mounted on the upper inside of the case 28, and the wires 17 and 18 of the casters 15 and 16 are connected to the operating lever 32 of the operating mechanism 31, and the operating lever 32 and the lock release button 33 are positioned on the upper outside of the case 28 facing forward. Here, each caster 15 (16) and the operating lever 32 are connected by a single wire 17 (18) that is not divided into multiple parts.

[0040] The operating unit 27 allows the bedside table 1 to be held in a stationary position. By pulling up the operating lever 32, which is located in a position that can be operated by hand, the wires 17 and 18 are pulled, locking the operating mechanism 31 and the casters 15 and 16. Pressing the lock release button 33 unlocks the operating mechanism 31, releasing the wires 17 and 18 and unlocking the casters 15 and 16, allowing the bedside table 1 to be moved. The safety of the bedside table 1 can be improved by positioning the operating lever 32 and the lock release button 33 in a location that is difficult for a person lying down to operate by mistake.

[0041] In the bedside table 1 described above, the operating mechanism 31 and the base ends of the wires 17 and 18 are housed inside the case 28 of the operating unit 27, and the operating unit 27 is attached to the front side of the fixed support column 5 of the support column 2, thereby providing the operating lever 32 on the fixed support column 5 of the support column 2. However, the design is not limited to this, and the operating mechanism 31 and the base ends of the wires 17 and 18 may be housed inside the fixed support column 5, or the operating mechanism 31 and the base ends of the wires 17 and 18 may be provided outside the fixed support column 5, with the operating lever 32 provided on the fixed support column 5 of the support column 2. Alternatively, the case 28 of the operating unit 27 may be directly and detachably attached to the fixed support column 5 of the support column 2 instead of the base 4, with the operating lever 32 provided on the fixed support column 5 of the support column 2.

[0042] Furthermore, in the bedside table 1 described above, since the single wire 17 (18) connecting each caster 15 (16) to the operating lever 32 is not housed in the top plate 3 which moves up and down with the raising and lowering of the top plate 8, or in the support column 2 which extends and retracts vertically, there is no need to provide space for the wires 17 and 18 to deform as the top plate 3 moves up and down (the support column 2 extends and retracts), the bedside table 1 can be made smaller (the support case 7 of the top plate 3 can be made thinner), and interference with the knees of a person lying on their side can be avoided.

[0043] Furthermore, in the bedside table 1 described above, the operating lever 32 and the lock release button 33 are housed in through holes 34 and 35 formed in the case 28 of the operating unit 27, so that the operating lever 32 and the lock release button 33 do not protrude forward from the case 28. This prevents the operating lever 32 and the lock release button 33 from being accidentally operated or colliding with a wall or the like.

[0044] Furthermore, in the bedside table 1 described above, notches 36 and 37 are formed in the support members 13 and 14, and the wires 17 and 18 of the casters 15 and 16 are passed through the notches 36 and 37. This allows the assembly to be done while the wires 17 and 18 remain connected to the casters 15 and 16, and also allows disassembly without separating the wires 17 and 18 from the casters 15 and 16, thereby improving work efficiency.

[0045] Furthermore, in the bedside table 1 described above, the operating section 27 (operating mechanism 31, operating lever 32, and lock release button 33) is located on a fixed support column 5 that is fixed to the base 4. As a result, the operating section 27 is concentrated on the lower side of the support column 2, which lowers the center of gravity of the bedside table 1 and improves its stability.

[0046] As described above, the bedside table 1 has a top plate 3 that can be raised and lowered on the base 4 via a vertically extendable support column 2, and casters 15 and 16 are mounted on the base 4 so as to be able to roll.

[0047] Furthermore, the bedside table 1 is configured such that a lifting support column 6 of the support column 2, which is connected to the top plate 3, can be raised and lowered relative to a fixed support column 5 of the support column 2, which is connected to the base 4. An operating lever 32 is connected to the casters 15 and 16 via wires 17 and 18, and the casters 15 and 16 can be locked or unlocked by slackening the wires 17 and 18 with the operating lever 32. The operating lever 32 is positioned so that it can be operated by hand, and the operating lever 32 and the casters 15 and 16 are connected by a single wire 17 and 18.

[0048] Therefore, with the above configuration of the bedside table 1, it is not necessary to connect or separate the wires 17 and 18 when assembling or disassembling the bedside table 1, thereby improving the workability of assembling, disassembling, and maintaining the bedside table 1.

[0049] Furthermore, the bedside table 1 described above is configured to be separable into a support column 2, a tabletop 3, and a base 4.

[0050] Therefore, with the above configuration, the bedside table 1 can be separated (disassembled) into the support column 2, the tabletop 3, and the base 4 for packaging and transport, and then assembled when setting up.

[0051] Furthermore, the bedside table 1 is configured such that the distance between the operating lever 32 and the casters 15 and 16 does not change even when the top plate 3 is raised or lowered.

[0052] Therefore, in the bedside table 1 with the above configuration, there is no need to provide space for the wires 17 and 18 to deform as the top plate 3 is raised or lowered (the support column 2 is extended or retracted), and the bedside table 1 can be made smaller.

[0053] Furthermore, the bedside table 1 has an operating lever 32 provided on the fixed support column 5 of the support column section 2.

[0054] Therefore, in the bedside table 1 with the above configuration, the wires 17 and 18 can be housed in the base 4 and fixed support 5, eliminating the need to house them in the lifting support 6 or the top plate 3. This also eliminates the need to provide space for the wires 17 and 18 to deform as the top plate 3 moves up and down (the support 2 extends and retracts), thus allowing for a smaller bedside table 1 (a thinner support case 7 for the top plate 3).

[0055] Furthermore, in the bedside table 1 with the above configuration, the operating lever 32 is provided on the fixed support column 5 rather than on the lifting support column 6 or the top plate 3. This increases the distance between the person lying down and the operating lever 32, as well as the distance from the lifting lever 9, etc., thereby preventing the person lying down from accidentally operating it and improving the safety of the bedside table 1.

[0056] Furthermore, the bedside table 1 has an operating section 27 that houses the operating lever 32 and wires 17 and 18, which is attached to the outside of the fixed support column 5 of the support column 2.

[0057] Therefore, with the above configuration, the bedside table 1 can be assembled without having to perform tasks such as connecting wires 17 and 18, thereby improving the ease of assembly, disassembly, and maintenance of the bedside table 1.

[0058] Furthermore, the bedside table 1 is configured such that the operating unit 27 is foldable up and down on the base 4, and the operating unit 27 can be positioned in a mounted position where it is upright relative to the base 4 and attached to the fixed support column 5 of the support column 2, and in a retracted position where it is folded down relative to the base 4 and housed along the base 4.

[0059] Therefore, with the above-described configuration of the bedside table 1, the bedside table 1 can be assembled without performing tasks such as connecting wires 17 and 18 by easily attaching the operating unit 27 to the support column 2 in the mounting position, and by placing the operating unit 27 in the storage position, the tabletop 3, support column 2, base 4, and operating unit 27 can be separated and easily transported.

[0060] Furthermore, the bedside table 1 is configured in such a way that the divided support column 2, tabletop 3, and base 4 can be connected directly to form the bedside table 1. Therefore, with the above configuration, the bedside table 1 can be assembled easily and quickly without adding any other components. [Explanation of Symbols]
