Description

[Technical field]

[0001] The present invention relates to a table. [Background technology]

[0002] Conventionally, there are known tables with adjustable tabletop heights (see, for example, Patent Documents 1 and 2). By adjusting the height of the tabletop to suit the physique of desk users and the standing position of desk users, desk users can maintain an ideal posture and perform their duties efficiently and effectively.

[0003] Also, an electric lifting unit that moves the tabletop up and down is known (see, for example, Patent Document 3). Such an electric lifting unit is configured to be extendable and retractable in the up and down direction by being driven by an electric motor. The operation of the lifting unit is controlled by a control unit that is separately attached to the table. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2017-79890 A [Patent Document 2] JP 2016-202883 A [Patent Document 3] Special Publication No. 2017-519546 Summary of the Invention [Problem to be solved by the invention]

[0005] When using a table with a liftable top, there is a demand for placing a storage fixture, such as a cart, below the top. Generally, a table with a liftable top is provided with a pair of legs with a lifting unit that support the top, but if a storage fixture is placed below the top in such a configuration, there is a concern that the storage fixture may come into contact with the legs with the lifting unit, causing the lifting unit to break down.

[0006] The present invention has been made to improve this current situation, and has an object to provide a table with sleeves that allows the height of the table top to be adjusted and prevents breakdowns in the lifting unit. [Means for solving the problem]

[0007] The table of the present invention is a table with sleeves in which a main body having at least one sleeve supports a tabletop, and the main body is equipped with a sleeve box that constitutes the sleeve and a lifting unit that supports the tabletop so that it can move in the vertical direction, and the lifting unit is arranged so that it cannot move relative to the sleeve box.

[0008] The table of the present invention has a main body in which a sleeve box is arranged below the top plate so that it cannot move relative to the lifting unit, thereby providing a storage function using the sleeve box while preventing failure of the lifting unit due to the sleeve box colliding with the lifting unit.

[0009] In the table of the present invention, the main body may have legs to which the lifting unit is connected on the side of the sleeve box, and may also have a support column cover attached to the side of the sleeve box and covering the lifting unit.

[0010] According to this embodiment, by integrating the lifting unit and the sleeve box, the installation area of ​​the legs can be increased, improving the stability of the legs. Furthermore, by covering the lifting unit with a support cover, the lifting unit can be protected by preventing foreign objects such as chairs from contacting the lifting unit, and safety can be improved by preventing table users from contacting the lifting unit.

[0011] Furthermore, the side of the sleeve box to which the lifting unit is connected may be one of the left and right sides parallel to the sliding direction of the drawer provided in the sleeve box, and the cover side portion of the pillar cover facing the side of the sleeve box may be provided with an inclined surface portion that slopes from the front side to the back side in a direction away from the sleeve box.

[0012] According to this embodiment, by covering the step between the side of the sleeve box and the lifting unit with the inclined surface portion of the pillar cover, the impact when the feet of a chair or table user come into contact with the pillar cover can be reduced, and damage or falling off of the pillar cover can be prevented.

[0013] Furthermore, the pillar cover may be made of sheet metal, and the cover side portion may be elastically deformable so as to press the front edge portion against the side of the sleeve box.

[0014] According to this aspect, the front edge of the support pillar cover can abut against the side of the sleeve box without any gap, thereby preventing the clothing of a table user from becoming caught in the gap between the support pillar cover and the sleeve box, thereby improving safety.

[0015] The table of the present invention may further comprise a pair of sleeve boxes arranged spaced apart in the left-right direction below the top plate, and the lifting unit may be connected to the left and right inward facing side surfaces of the sleeve boxes.

[0016] According to this aspect, by providing the lifting unit on the left and right inward side surfaces of the sleeve box, the flat left and right outward side surfaces of the sleeve box can be used as the left and right side edges of the table, resulting in a neat appearance. Also, when multiple tables are arranged side by side, the sleeve boxes can be placed adjacent to each other to reduce the gap between adjacent tables. Effect of the Invention

[0017] The present invention can provide a table with sleeves that allows the height of the table top to be adjusted and prevents breakdowns in the lifting unit. [Brief description of the drawings]

[0019] Next, an embodiment of the present invention will be described with reference to the drawings. In this specification, for convenience, terms such as front / rear, left / right, front, back, etc. are used to specify directions, but the direction in which a pair of legs 4, 4 are arranged is the left / right direction, and the direction perpendicular to the left / right direction in a horizontal plane is the front / rear direction. Note that the present invention is not limited to the configuration in the directions specified in the embodiment described below.

[0020] As shown in Figures 1 to 4, the table 1 with sleeves is a table with sleeves in which a main body 30 having a sleeve box 5 constituting the sleeve supports a top board 2. The main body 30 includes the sleeve box 5 capable of storing items, and legs 4 having an electric lifting unit 3 that supports the top board 2 so that it can move up and down. In this embodiment, the pair of legs 4, 4 are arranged spaced apart in the left-right direction (width direction).

[0021] The top plate 2 is provided with a first drawer 23 provided on the front left edge, a second drawer 24 provided in the front center, and an auxiliary top plate 25 provided on the front right edge. The auxiliary top plate 25 is connected to the top plate 2 by an auxiliary top plate bracket 26 attached to the underside of the top plate 2 and the underside of the auxiliary top plate 25. In addition, three outlet boxes 27 arranged in the left-right direction are disposed near the back of the upper surface of the top plate 2. A back panel 28 is connected to the back edge of the top plate 2 via an L-shaped bracket 281. A horizontally elongated wiring receptacle 29 disposed below the outlet boxes 27 is attached to the bottom surface of the top plate 2 near the back.

[0022] Each leg 4 includes a sleeve box 5 placed on the floor surface, and a lifting unit 3 connected to the left and right inward side surfaces 51 of the sleeve box 5. The sleeve box 5 has a substantially rectangular box shape and is disposed below the tabletop 2 with the left and right inward side surfaces 51 aligned in the front-to-rear direction. The main body 30 includes a skirt panel 11 in an upright position that extends in the left-right direction below the tabletop 2 and connects the rear portions of the left and right sleeve boxes 5 to each other.

[0023] The sleeve box 5 has a storage function, with multiple drawers 52 on the front side that can be pulled out toward the front. The sleeve box top surface 53 is disposed opposite the underside of the tabletop 2. The sleeve box 5 has sleeve box adjusters 54 at the four corners of its underside for adjusting the height and horizontality of the sleeve box 5.

[0024] The lifting unit 3 is configured to be extendable and retractable in the vertical direction. Specifically, the lifting unit 3 includes a housing portion 31 that houses a drive source such as an electric motor, an inner cylinder member 32 connected to the lower surface of the housing portion 31, and an outer cylinder member 33 that covers the outer periphery of the inner cylinder member 32. The cylinder members 32 and 33 are each formed in a rectangular cylinder shape extending in the vertical direction.

[0025] A drive mechanism is provided inside the housing part 31 and the tubular members 32, 33, for vertically moving the housing part 31 and the inner tubular member 32 relative to the outer tubular member 33. The lifting unit 3 is configured to be able to extend and retract in the vertical direction by operating the drive mechanism using a drive source such as an electric motor inside the housing part 31.

[0026] 7 and 8, the bottom of the outer tube member 33 is supported by a support bracket 6 fixed to a portion near the lower edge of the left and right inward side surfaces 51 of the sleeve box 5. The support bracket 6 is made of metal and has a roughly L-shaped cross section, extends along the front-to-rear direction, and includes an upright piece 61 screwed to a portion near the lower edge of the left and right inward side surfaces 51 of the sleeve box 5, and a horizontal piece 62 extending inwardly to the left and right from the lower end of the upright piece 61.

[0027] The horizontal piece 62 is provided at approximately the same height as the underside of the sleeve box 5, and is spaced apart from the floor. A pair of front and rear bracket adjusters 63 for adjusting the height and horizontality of the support bracket 6 are provided near the front and rear edges of the horizontal piece 62. The bottom of the outer tube member 33 is fixed with bolts to a portion of the upper surface of the horizontal piece 62 near the front-to-rear center. The leg 4 supports the top plate 2 and the lifting unit 3 with the sleeve box adjuster 54 and bracket adjuster 63, so that the installation area of ​​the leg 4 is large and highly stable.

[0028] 5, the housing portion 31 of the lifting unit 3 is connected to a pair of left and right arm members 21 attached to the underside of the tabletop 2 with a space between them in the left and right direction. The arm members 21 have a generally L-shaped cross section, extend along the front-rear direction, and include a fixing piece 211 fixed with a bolt to the underside of the tabletop 2, and a unit fixing piece 212 extending downward from the inner left and right edges of the fixing piece 211. As can be seen from FIG. 2 etc., the unit fixing piece 212 is formed in a generally isosceles trapezoid with a lower edge shorter than an upper edge.

[0029] A gutter-shaped beam member 22 extending in the left-right direction is fixed with bolts to the underside of the tabletop 2 at a position between the left and right arm members 21. Both left and right ends of the beam member 22 are disposed adjacent to the arm members 21. A housing portion 31 of the lifting unit 3 is disposed inside the left and right edges of the beam member 22 and is fixed with bolts to the front and rear side portions of the beam member 22 as well as to a unit fixing piece portion 212 of the arm member 21.

[0030] A control unit 10 is housed inside the beam member 22 and bolted to the underside of the tabletop 2 between the left and right housing parts 31. The control unit 10 controls the operation of the lifting unit 3, and causes the lifting unit 3 to extend and retract in response to an input signal from an operation switch 12 (see FIG. 5). In this way, the legs 4 carrying the lifting unit 3 support the tabletop 2 so that it can be raised and lowered.

[0031] As described above, in the table 1 of this embodiment, the main body 30 supporting the top plate 2 includes a sleeve box 5 constituting a sleeve, and a lifting unit 3 supporting the top plate 2 so as to be movable in the vertical direction, and the lifting unit 3 is arranged so as not to be movable relative to the sleeve box 5. This allows the table 1 to meet the need to place a sleeve box 5 having a storage function below the liftable top plate 2, while preventing failure of the lifting unit 3 due to the sleeve box 5 colliding with the lifting unit 3. Furthermore, the table 1 includes legs 4 which are formed by connecting the lifting unit 3 to the side of the sleeve box 5 and integrating the lifting unit 3 and the sleeve box 5, thereby increasing the installation area of ​​the legs 4 and improving the stability of the legs 4.

[0032] The table 1 also has a pair of legs 4 spaced apart in the left-right direction below the top plate 2, and each leg 4 has a sleeve box 5. The table 1 has a large storage capacity due to the pair of left and right sleeve boxes 5. Furthermore, by providing the lifting unit 3 on the left and right inward side surfaces 51 of the sleeve box 5 in each leg 4, the flat left and right outward side surfaces 55 of the sleeve box 5 can be used as the left and right side edges of the table 1, resulting in a neat and tidy appearance. Furthermore, when multiple tables 1 are arranged next to each other, the sleeve boxes 5 can be adjacent to each other to reduce the gap between the tables 1.

[0033] 6 to 8, a vertical midpoint of the outer tube member 33 is connected to a portion near the upper edge of the left and right inward side surfaces 51 of the sleeve box 5 via a hat-shaped top plate vibration prevention member 7. The top plate vibration prevention member 7 is made of metal and includes a pair of front and rear hat side portions 71 that sandwich the outer tube member 33, a hat bottom portion 72 that connects the left and right inner edge portions of the front and rear hat side portions 71, and a pair of front and rear hat flange portions 73 that extend outward in the front and rear directions from the left and right outer edge portions of the hat side portions 71.

[0034] The front and rear hat side portions 71 are spaced apart slightly larger than the front-to-rear width of the outer tube member 33. Elastic bodies 74, such as rubber plates, are fixed to the inner wall surfaces of the hat side portions 71. The tabletop vibration prevention member 7 is fitted into the outer tube member 33 from the left and right inside, the outer tube member 33 is clamped by the elastic bodies 74 fixed to the front and rear hat side portions 71, and the left and right inward side portions of the outer tube member 33 are positioned close to the hat bottom portion 72. Then, each hat flange portion 73 is screwed to the left and right inward side surfaces 51 of the sleeve box 5 by a pair of upper and lower screw members.

[0035] This suppresses the front-back and left-right swinging of the lifting unit 3 with the bottom of the outer tubular member 33 fixed to the support bracket 6 as a fulcrum, thereby suppressing the swinging of the tabletop 2. In addition, by interposing an elastic body 74 between the hat side surface portion 71 and the outer tubular member 33, contact between the hat side surface portion 71 and the outer tubular member 33 can be prevented, and the force transmitted from the outer tubular member 33 to the tabletop swing prevention member 7 can be absorbed, preventing damage to the tabletop swing prevention member 7 and the outer tubular member 33. An elastic body such as a rubber plate may be interposed between the outer tubular member 33 and the hat bottom surface portion 72.

[0036] 1, 3 to 6, 8, etc., the leg portion 4 is provided with a support column cover 8 which is detachably attached to the left and right inward side surfaces 51 of the sleeve box 5 to cover the lifting unit 3. The support column cover 8 is provided with a cover side portion 81 which faces the left and right inward side surfaces 51 of the sleeve box 5. The cover side portion 81 is made of sheet metal and is provided with an inclined surface portion 811 which covers the front side of the outer tube member 33 of the lifting unit 3, a parallel surface portion 812 which covers the left and right inner sides of the outer tube member 33, and a back portion 813 which covers the rear side of the outer tube member 33. The height dimension of the cover side portion 81 is approximately the same as the height dimension of the left and right inward side surfaces 51 of the sleeve box 5.

[0037] The front edge 82 of the cover side portion 81 (the front edge of the inclined surface portion 811) is provided in an approximately vertical position along the front edge of the left and right inward side surfaces 51. The inclined surface portion 811 is inclined from the front side toward the rear side in a direction away from the sleeve box 5. The rear edge of the inclined surface portion 811 is disposed left and right more inward than the outer tube member 33 of the lifting unit 3 when viewed from the front. The parallel surface portion 812 extends from the rear edge of the inclined surface portion 811 toward the rear side approximately parallel to the left and right inward side surfaces 51, and is disposed at a distance from the outer tube member 33. The back portion 813 extends from the rear edge of the parallel surface portion 812 toward the sleeve box 5, and is disposed in an approximately perpendicular position to the left and right inward side surfaces 51.

[0038] Mounting surface portions 83 that come into contact with the left and right inward side surfaces 51 extend from left and right outer edge portions (edge ​​portions opposite the parallel surface portions 812) of the back surface portion 813. The mounting surface portions 83 are disposed at positions spaced apart from the rear edge portions of the left and right inward side surfaces 51. An upper surface portion 84 that covers the upper part of the space between the back surface portion 813 and the outer tubular member 33 extends from a portion near the rear edge portions of the upper ends of the parallel surface portions 812 of the left and right inward side surfaces 51.

[0039] The support column cover 8 includes a pair of upper and lower mounting brackets 85 fixed to the surfaces of the inclined surface portion 811 facing the left and right inward side surfaces 51. The mounting brackets 85 are made of metal and include a substantially rectangular first surface portion 851 fixed to the inclined surface portion 811 by welding or the like, a substantially triangular second surface portion 852 extending from the upper and lower outer edges of the first surface portion 851 toward the left and right inward side surfaces 51, and a substantially rectangular third surface portion 853 extending inwardly upward and downward from a rear portion of the left and right outer edges of the second surface portion 852 (edges opposite to the first surface portion 851) and abutting the left and right inward side surfaces 51. A front edge portion of the first surface portion 851 is provided at a distance from the front edge portion 82 of the support column cover 8.

[0040] The upper mounting bracket 85 is provided along the upper end of the inclined surface portion 811. On the other hand, the lower mounting bracket 85 is provided away from the lower end of the inclined surface portion 811 to avoid interference with the support bracket 6.

[0041] The mounting bracket 85 is engaged with a pair of upper and lower first clip members 56 that have mounting holes 854 provided in the third surface portion 853 and are screwed to the left and right inward side surfaces 51 of the sleeve box 5. In addition, the mounting surface portion 83 of the support column cover 8 is screwed to the left and right inward side surfaces 51 by inserting fixing screws 58 that have passed through second clip members 57 into a pair of upper and lower screw insertion holes 831 provided in the mounting surface portion 83.

[0042] 9, the first clip member 56 has a generally convex shape with a small diameter portion 562 on one end surface of a large diameter portion 561. The mounting hole 854 is formed in a keyhole shape with a large diameter hole 855 and a small diameter hole 856 connected to each other. The diameter of the large diameter hole 855 is larger than the large diameter portion 561 of the first clip member 56, and the diameter of the small diameter hole 856 is smaller than the large diameter portion 561 of the first clip member 56 and slightly larger than the small diameter portion 562. This allows the mounting bracket 85 to be attached and detached without removing the first clip member 56 from the sleeve box 5.

[0043] When attaching the pillar cover 8 to the sleeve box 5, first, the upper and lower first clip members 56 are fitted into the large diameter holes 855 of the mounting holes 854 (see FIG. 9(A)). The front edge portion 82 of the pillar cover 8 is located slightly outboard (toward the left and right inward side surfaces 51) of the third surface portion 853 of the mounting bracket 85, and with the front edge portion 82 and the mounting surface portion 83 in contact with the left and right inward side surfaces 51, the mounting bracket 85 rises slightly from the left and right inward side surfaces 51.

[0044] When the column cover 8 is pushed toward the left and right inward side surfaces 51, the portions of the inclined surface portions 811 near the front edge portions 82 are elastically deformed, the third surface portions 853 of the mounting brackets 85 come into contact with the left and right inward side surfaces 51, and the small diameter holes 856 of the mounting holes 854 are positioned on the rear side of the small diameter portions 562 of the first clip members 56 (see FIG. 9(B)). Then, when the column cover 8 is slid toward the front side and the small diameter portions 562 of the first clip members 56 are engaged with the small diameter holes 856 of the mounting holes 854, the front edge portions 82 of the column cover 8 are disposed along the front edges of the left and right inward side surfaces 51 without floating up (see FIG. 9(C)).

[0045] In this way, the support column cover 8 is provided so that the sheet metal cover side portion 81 can be elastically deformed to press the front edge portion 82 against the left and right inward side surfaces 51 of the sleeve box 5, so that the front edge portion 82 can abut against the left and right inward side surfaces 51 without any gaps. This prevents the clothes of a table user from getting caught in the gap between the sleeve box 5 and the support column cover 8, improving safety.

[0046] When the small diameter portion 562 of the first clip member 56 is engaged with the small diameter hole 856 of the mounting hole 854, the screw insertion hole 831 of the mounting surface portion 83 is aligned with the screw mounting hole 511 drilled in the left and right inward side surfaces 51. The fixing screw 58, which has been inserted through the second clip member 57 having the same shape as the first clip member 56, is screwed into the screw mounting hole 511 through the screw insertion hole 831, and the second clip member 57 and the mounting surface portion 83 are fastened together to the left and right inward side surfaces 51. This completes the attachment of the support cover 8 to the sleeve box 5.

[0047] By covering the lifting unit 3 with the support cover 8, the table 1 can protect the lifting unit 3 by preventing foreign objects such as chairs from coming into contact with the lifting unit 3, and can improve safety by preventing the table user from coming into contact with the lifting unit 3. Furthermore, by covering the step between the left and right inward side surfaces 51 of the sleeve box 5 and the lifting unit 3 with the inclined surface portions 811 of the support cover 8, it is possible to reduce the impact when a chair or the feet of a table user come into contact with the support cover 8, and prevent the support cover 8 from being damaged or falling off.

[0048] 3 to 6 and 10, a wiring duct 9, through which wiring can be inserted in the vertical direction, is removably attached to a rear portion of the left and right inward side surfaces 51 of the sleeve box 5. The wiring duct 9 is made of sheet metal and has a generally C-shaped cross section, and includes a pair of duct side sections 91 spaced apart from each other in the front and rear, duct parallel surface sections 92 connecting the left and right inner edge sections of the front and rear duct side sections 91, and a pair of front and rear duct flange sections 93 extending inwardly from the left and right outer edge sections of the duct side sections 91 in the front and rear directions.

[0049] A pair of upper and lower mounting holes 94 are formed in the duct flange portion 93. The wiring duct 9 is detachably attached to the sleeve box 5 by engaging the mounting holes 94 with the second clip member 57 and the third clip member 59 screwed to the left and right inward side surfaces 51 of the sleeve box 5. As described above, the pair of upper and lower second clip members 57 fix the mounting surface portion 83 of the pillar cover 8 to the left and right inward side surfaces 51. The pair of upper and lower third clip members 59 have the same shape as the first and second clip members 56, 57, and are screwed to the left and right inward side surfaces 51 behind the second clip members 57.

[0050] The mounting hole 94 has the same shape as the mounting hole 854 (see FIGS. 8 and 9) of the above-mentioned support pole cover 8, and is formed in a keyhole shape with a large diameter hole 941 and a small diameter hole 942 connected to each other. That is, the diameter of the large diameter hole 941 of the mounting hole 94 is larger than the large diameter portion of the third clip member 59, and the diameter of the small diameter hole 942 is smaller than the large diameter portion of the third clip member 59 and slightly larger than the small diameter portion.

[0051] When attaching the wiring duct 9 to the sleeve box 5, first, the large diameter holes 941 of the mounting holes 94 are fitted into the four third clip members 59 on the top, bottom, left and right. The front duct flange portion 93 is abutted against the mounting surface portion 83 of the pillar cover 8, and the rear duct flange portion 93 is abutted against the left and right inward side surfaces 51, so that the small diameter holes 942 of the mounting holes 94 are positioned above the small diameter portions of the third clip members 59. Then, the wiring duct 9 is slid toward the front side and the small diameter portions of the third clip members 59 engage with the small diameter holes 942 of the mounting holes 94, whereby the wiring duct 9 is held in the sleeve box 5 so as not to fall off.

[0052] The height of the wiring duct 9 is approximately the same as the height of the pillar cover 8. The left-right width of the duct side portion 91 is approximately the same as the left-right width of the back portion 813 of the pillar cover 8, and the duct parallel surface portion 92 is disposed approximately flush with the parallel surface portion 812 of the pillar cover 8 along the front-to-rear direction. The front duct side portion 91 is disposed close to the back portion 813 of the pillar cover 8. The rear duct side portion 91 is disposed spaced apart from the rear edge portions of the left and right inward side portions 51. The left and right edges of the upright fascia panel 11 are attached to the rear edge portions of the left and right inward side portions 51.

[0053] As shown in Fig. 5, a wiring insertion hole 291 is provided on the bottom surface of the wiring receiver 29 above the wiring duct 9. The wiring pulled downward from the wiring insertion hole 291 passes through the wiring duct 9, and can be pulled out onto the floor surface through the gap between the rear edge of the horizontal piece 62 of the support bracket 6 and the rear duct side surface 91. When the tabletop 2 is lowered, the wiring pulled downward from the wiring insertion hole 291 can be folded and stored inside the wiring duct 9. This prevents excess wiring from hanging down toward the center under the tabletop 2, improving safety and appearance.

[0054] As shown in FIG. 11, the arm member 21 that fixes the housing part 31 of the lifting unit 3 to the top plate 2 is disposed above the sleeve box 5. As also shown in FIG. 2, the arm member 21 has a horizontal piece 213 that extends outward to the left and right from the lower edge of the unit fixing piece 212. When the lifting unit 3 is contracted to lower the top plate 2, the horizontal piece 213 increases the contact area between the arm member 21 and the sleeve box top surface 53 when the arm member 21 comes into contact with the sleeve box top surface 53, thereby dispersing the concentration of the load on the sleeve box top surface 53 and preventing the sleeve box top surface 53 from being dented. In addition, even when a foreign object such as a user's finger is caught between the horizontal piece 213 and the sleeve box top surface 53, the horizontal piece 213 can disperse the concentration of the load, thereby improving safety.

[0055] As can be seen from Figures 1 and 11, the left and right edges of the table top 2 are disposed left and right inward by dimension S (see Figure 11) from the left and right outward side surfaces 55 of the sleeve box 5. As a result, when multiple tables 1 are arranged adjacent to each other left and right, a gap is formed between the table tops 2 of adjacent tables 1. This prevents foreign objects such as the user's fingers from becoming caught between the left and right table tops 2 when the table tops 2 are raised and lowered, improving safety.

[0056] As shown in Figures 2 and 5, the auxiliary top plate bracket 26 that connects the auxiliary top plate 25 to the top plate 2 is made of metal and is bolted across the lower surface of the top plate 2 and the lower surface of the auxiliary top plate 25. The auxiliary top plate 25 and the top plate 2 have the same thickness, the upper surface of the auxiliary top plate 25 is flush with the upper surface of the top plate 2, and the lower surface of the auxiliary top plate 25 is flush with the lower surface of the top plate 2. The bottom surface of the auxiliary top plate bracket 26 is inclined so that it is farther away from the lower surface of the top plate 2 and the auxiliary top plate 25 as it approaches the back. This makes it possible to reduce the downward protruding height of the auxiliary top plate bracket 26 relative to the lower surface of the auxiliary top plate 25, thereby reducing the chance that the feet of a user working on the front side of the table 1 come into contact with the auxiliary top plate bracket 26, improving convenience.

[0057] Although the embodiment of the present invention has been described above, the present invention can be embodied in various other ways and various modifications can be made without departing from the spirit of the present invention.

[0058] For example, in the table of the present invention, one of the left and right legs 4 may be provided with the lifting unit 3 and the sleeve box 5, and the other leg 4 may not be provided with the sleeve box 5 but may be provided with the lifting unit 3 and a grounding leg connected to the lower end of the lifting unit 3 (see, for example, Patent Document 1). The lifting unit 3 may be attached to the left or right outward side surface 55 of the sleeve box 5, or may be attached to the back surface of the sleeve box 5. The leg 4 is not limited to a configuration in which the lifting unit 3 is connected to the side surface of the sleeve box 5. For example, the leg 4 may be formed by connecting the lifting unit 3 to a back panel 11 connected to the sleeve box 5, and any other configuration may be used as long as the lifting unit 3 is arranged in the sleeve box 5 arranged below the top plate 2 so as to be immovable relative to the sleeve box 5.

[0059] Furthermore, the lifting unit 3 is not limited to having two square tubular members 32, 33, but may have three or more extendable tubular members, and the tubular members may be cylindrical. The first drawer 23, second drawer 24, auxiliary top plate 25, outlet box 27, and back panel 28 attached to the top plate 2 can be appropriately attached according to the user's needs. For example, the auxiliary top plate 25 can be attached instead of the first drawer 23, or the first drawer 23 can be attached instead of the auxiliary top plate 25. [Explanation of symbols]
