Description

  The present invention relates to a desk-lifting desk capable of moving the height of a desk in the vertical direction according to the request of an office worker in an office space such as an office or public facilities.

In working spaces such as offices and public facilities, desk devices (desks) are generally provided to provide work areas for users (office workers). The height of the top of the desk device, which is easy to work with, depending on the user's physical constitution, sex, and preferences, varies greatly depending on the individual. Such a situation can not be coped with by a desk device whose top height is constant. For this reason, a table-lifting desk that can move the height of the table in the vertical direction is used.
By using such a top-lifting desk, it is possible to provide a work area with a top height according to the user's request, improve work efficiency, and reduce the load on the user's body. Can.

  As a lifting and lowering mechanism unit for moving the top plate in the vertical direction, a mechanism using a gas spring, a mechanism using a gear, an electric mechanism and the like have been invented (see, for example, Patent Documents 1 to 5).

It is necessary to provide an operation unit such as a lever or the like for instructing the lifting and lowering mechanism unit to move the lifting and lowering operation of the top plate on the desk and lift type desk using the lifting and lowering mechanism unit.
However, since the upper surface of the top plate of the desk is a work surface of the user, if the operation unit is provided on the top plate, the work surface is narrowed. For this reason, the operation unit is often provided below the top plate.
However, in the table-lifting desk where the operation unit is provided below the tabletop, other fixtures used around the desk or the user's own leg collide with the operation unit, and the lifting mechanism unit becomes the user's There is a risk of operating contrary to intention. In addition, since the operation portion protrudes below the top plate, there is a risk that the operation portion may collide with an obstacle when the top plate is moved up and down (in particular, when it is lowered).

In connection with such a problem, Patent Document 6 describes a desk-lifting desk having a structure in which an operating portion is accommodated in a recess formed on the lower surface of the desk-top. In this structure, when the fixture or the foot or the like approaches the operation unit from below the top plate, the fixture or foot comes in contact with the operation unit before or at the same time as contacting the operation unit, and simultaneously contacts the lower surface of the top plate. In addition, even when the user operates the operation unit to move the top plate downward, the fixtures or feet contact the operation unit before or at the same time the fixtures or feet touch the lower surface of the top plate. Contact.
Therefore, in the top board lifting type desk described in Patent Document 6, the operating unit is pushed by the fixture, the foot, etc., and the elevating mechanism unit operates against the user's intention or the operating unit collides with an obstacle. Being suppressed.

First Embodiment
Hereinafter, one embodiment of a top board lift type desk according to the present invention will be described with reference to FIGS. 1 to 3.
In the following description, the side on which the user works may be referred to as the “front” of the top-lifting desk (or its components), and the opposite side may be referred to as the “rear”. The XYZ axes may be set, and the positional relationship of each component may be described with reference to the XYZ axes. In the top-lifting desk, the X-axis direction is the left-right direction, the Y-axis direction is the front-back direction, and the Z-axis direction is the up-down direction.

  FIG. 1 is a perspective view of the table-lifting desk 1 according to the present embodiment. As shown in FIG. 1, the top-lifting-type desk 1 of the present embodiment includes a top 10, a leg 20, and an operation unit 30A.

The top plate 10 has an upper surface 10a serving as a work surface of the user Q (see FIG. 3), a lower surface 10b facing the upper surface 10a, and a side surface 10c connecting the upper surface 10a and the lower surface 10b.
The top 10 is formed in a rectangular shape when viewed parallel to the Z-axis direction, and has a pair of first sides 10 d and a pair of second sides 10 e. The first side 10 d is a side extending in the X-axis direction, and the second side 10 e is a side extending in the Y-axis direction.
Of the pair of first sides 10d of the top 10, a first side 10d1 on the front side is a side that the user Q mainly faces.
The side surface 10c1 located at a position along the first side 10d1 of the side surface 10c of the top 10 is a side that the user Q mainly faces.

  Fig.2 (a) is a perspective view which shows the structure of the principal part of the top-plate raising / lowering desk 1 of this embodiment. As shown to FIG. 1 and FIG. 2 (a), the notch 11 is formed in the edge part (front edge part) of the top plate 10 in alignment with 1st edge | side 10 d1. The notch portion 11 is a concave portion provided at an edge (front edge) of the top plate 10. The notch portion 11 is formed to connect the upper surface 10 a and the lower surface 10 b of the top plate 10 (to communicate in the Z-axis direction). Further, the notch 11 is formed to open the side surface 10c1, and the opening enters rearward. The size of the notch 11 is a size that can accommodate the operation unit 30A. That is, the notch 11 is a concave portion having substantially the same outer shape as the operation unit 30A.

  The leg 20 has a lower support 21 disposed on the floor F, an upper support 22 disposed above the lower support 21 and an upper end portion supporting the top plate 10, and the lower support 21 and the upper support. A lift mechanism unit 23 is connected to be telescopically connected to the gear 22. As shown in FIG. 1, each of the pair of legs 20 is spaced apart in the X-axis direction.

  As shown in FIG. 1, the lower support 21 has a ground frame 25 extending in the Y-axis direction, and an adjuster 26 provided on the lower front and rear lower surfaces of the ground frame 25 and in contact with the floor surface F. . For example, the ground contact frame 25 is formed by bending a steel plate to form a square cylinder. The adjuster 26 is of known construction. By moving the adjuster 26 in the Z-axis direction with respect to the ground contact frame 25, it is possible to adjust the unevenness of the top board lifting type desk 1.

  The upper support 22 is configured similarly to the ground frame 25. The upper support 22 is fixed to the lower surface 10 b of the top plate 10 by a screw member or the like (not shown).

The lift mechanism unit 23 is an electrically driven unit having a known configuration. The elevating mechanism unit 23 has a plurality of square cylinders 23a, 23b and 23c having different outer diameter dimensions, and a drive mechanism (not shown) accommodated inside the square cylinders 23a, 23b and 23c.
The rectangular cylinders 23a, 23b, and 23c are engaged with each other so as to be movable relative to each other in the Z-axis direction, and by driving the drive mechanism, the elevating mechanism unit 23 can be extended or contracted in the Z-axis direction. As a result, the elevating mechanism unit 23 connects the lower support 21 and the upper support 22 in an extensible manner, and moves the top 10 in the Z-axis direction.

The operation unit 30A includes an operation unit 31A that drives the elevation mechanism unit 23, and a display unit 32 that displays information on elevation of the top 10.
The operation unit 31A constituting the operation unit 30A is connected to the pair of lift mechanism units 23 via the lift control unit 40, and drives the pair of lift mechanism units 23.
The display unit 32 constituting the operation unit 30A is connected to the elevation control unit 40, and displays information on elevation of the top 10 transmitted from the elevation control unit 40.
As shown to FIG. 1 and FIG. 2 (a), the display part 32 is arrange | positioned above the operation part 31A. Therefore, when the user carries out the work on the upper surface 10a of the top 10, the possibility that the user unintentionally contacts the operation portion 31A can be reduced.

FIG. 3 is a cross-sectional view taken along the line AA in FIG.
As shown in FIG. 2A and FIG. 3, the entire operation unit 30A is accommodated in the notch 11. Since the operation unit 30A is accommodated in the notch 11 of the top plate 10, the entire operation unit 30A falls within the thickness and width of the top plate 10, and the user Q is caught on the operation unit 30A. It can prevent the situation.

  The operation unit 31A constituting the operation unit 30A has an operation lever (operation member) 37 operated by the user Q, and a mounting portion 33 for mounting the operation lever 37. As shown in FIG. 2A and FIG. 3, the attachment portion 33 connects a pair of side pieces 33 a arranged to sandwich the operation lever 37 in the X-axis direction and a rear end of the pair of side pieces 33 a A rear piece 33c and a lid piece 33b which is disposed so as to cover the operation lever 37 and which connects the upper end portions of the pair of side pieces 33a and the upper end portion of the rear piece 33c are provided. The mounting portion 33 has an opening at the front and the lower surface, and the operation lever 37 is mounted in the opening. Therefore, the user Q can access the operation lever (operation member) 37 with the index finger Q1 or the like from the front or lower side of the operation unit 30A (the operation unit 31A).

The display unit 32 constituting the operation unit 30A is disposed above the cover piece 33b of the attachment unit 33. The display unit 32 is configured of a thin display such as a liquid crystal display, an organic EL display, or an LED display.
As shown in FIGS. 2A and 3, the display surface 32 a of the display unit 32 is disposed to be flush with the upper surface 10 a of the top plate 10.
Note that "to form the same surface" is not limited to the case of completely the same surface, but also includes a case of substantially the same surface or substantially the same surface, and the same applies in the following description. For example, when the load placed on the upper surface 10a of the top 10 is moved along the upper surface 10a, a step is generated between the display surface 32a and the upper surface 10a to prevent smooth movement of the load. If not, it can be said that the display surface 32a and the upper surface 10a are in the same plane. Further, even if an unintended level difference in manufacturing technology occurs between the display surface 32a and the upper surface 10a, it can be said that the display surface 32a and the upper surface 10a are in the same plane.

The operation unit 31A has a flange portion 34 for attaching the operation unit 30A to the top plate 10. The flange portion 34 extends outward along the lower surface 10 b of the top plate 10 from the lower end portion of the attachment portion 33 (side piece 33 a). The lower surface of the flange portion 34 which constitutes a part of the lower end portion of the operation unit 30A is disposed at a position flush with the lower surface 10b of the top plate 10 or above the lower surface 10b. That is, the lower surface 10 b of the top plate 10 is provided with a concave portion formed so as to be able to accommodate the flange portion 34.
The flange portion 34 has a through hole 35. The operation unit 30A is attached to the top plate 10 by inserting the screw member 36 into the through hole 35 of the flange portion 34.

  The mounting portion 33 and the flange portion 34 can be formed of a known metal material or resin material, and may be integrally formed.

As shown in FIG. 3, the operation unit 31 </ b> A includes an operation lever (operation member) 37 and a support unit 38.
The control lever 37 has a plate-like lever main body 37a extending in the X-axis direction and the Z-axis direction at the front end, a plate-like connecting piece 37c extending in the X-axis direction and the Z-axis direction at the rear end, It is comprised from the plate-shaped intermediate piece 37b which connects the lower end part of 37a, and the lower end part of the connection piece 37c. The connection piece 37c is formed with a through hole extending in the X-axis direction.

  The support portion 38 has a plurality of support legs 38 b attached to the rear piece 33 c of the attachment portion 33 and a shaft member 38 a supported by the plurality of support legs 38 b. The plurality of support legs 38 b are arranged to sandwich the control lever 37 in the X-axis direction. The shaft member 38a is inserted into the through hole of the connection piece 37c. For this reason, the control lever 37 is rotatably supported about the shaft member 38a.

As the connection piece 37c rotates around the shaft member 38a, the control lever 37 is close to the neutral position P1 where the intermediate piece 37b is parallel to the upper surface 10a of the top plate 10, and the lever main body 37a is close to the upper surface 10a of the top plate 10 It can move to the 1st movement position P2 used as a position, and the 2nd movement position P3 used as the position where the lever main body 37a is close to the lower surface 10b of the top plate 10. Note that movement means both parallel movement and rotational movement, and movement in the present embodiment means rotational movement.
The operating lever 37 is preferably biased by a spring member so that the operating lever 37 moves from the first moving position P2 or the second moving position P3 to the neutral position P1 when the operating lever 37 is not operated. .
The control lever 37 is disposed at the same position as the lower surface 10b of the top plate 10 or above the lower surface 10b at any position of the neutral position P1, the first movement position P2 and the second movement position P3. It is done.

  The control lever 37 and the support portion 38 can be formed of resin, metal or the like.

As shown in FIG. 3, the operation unit 31A incorporates a position detection sensor (not shown), and the position detection sensor is connected to the elevation control unit 40 (see FIG. 1) via the wiring 41. The position detection sensor is connected to the control lever 37 and detects the movement of the control lever 37. That is, the position detection sensor detects which of the neutral position P1, the first movement position P2, and the second movement position P3 the control lever 37 is in. The position detection sensor transmits the detection result to the elevation control unit 40 via the wiring 41.
The elevation control unit 40 extends and retracts the pair of elevation mechanism units 23 according to the movement direction of the operation lever 37 detected by the position detection sensor.

As shown in FIG. 3, the display unit 32 is connected to the elevation control unit 40 (see FIG. 1) through the wiring 42. The display unit 32 receives information on the elevation of the top 10 from the elevation control unit 40, and displays the information on the display surface 32a.
The information on the elevation of the top 10 displayed by the display unit 32 is, for example, whether the power of the elevation mechanism unit 23 is turned on or not, or the elevation mechanism unit 23 is in the upward movement, the downward movement, or the temporary stop. Or the height of the top 10 from the floor surface F, error information regarding the raising and lowering operation, and the like.

The elevation control unit 40 (see FIG. 1) has a control circuit (not shown), a memory in which a control program for controlling the control circuit, and the like are stored.
The control circuit extends the pair of lifting mechanism units 23 when detecting that the operation lever 37 has moved to the first movement position P2 based on the detection result transmitted from the position detection sensor of the operation unit 31A. .
The control circuit retracts the pair of lifting mechanism units 23 when detecting that the operation lever 37 has moved to the second movement position P3 based on the detection result transmitted from the position detection sensor of the operation unit 31A. .
That is, the operation unit 31A drives the elevation mechanism unit 23 according to the movement of the operation lever 37 via the control circuit of the elevation control unit 40.
The above-described drive mechanism, the wiring 41, the wiring 42, and the power supply cable 50 (see FIG. 1) are connected to the elevation control unit 40. The power cable 50 is provided with a plug (not shown).

Next, the operation of the desk-lifting desk 1 configured as described above will be described.
When the plug of the power cable 50 is inserted into an outlet (not shown), the control circuit of the elevation control unit 40 is activated. When the user Q wants to move the top 10 up and down, the user Q tries to grasp the position of the operation unit 31A. According to the top board lifting type desk 1 of the present embodiment, the display unit 32 having the display surface 32a which is flush with the upper surface 10a of the top board 10 is provided in the operation unit 30A having the operation section 31A. For this reason, the user Q recognizes at a glance the position of the operation unit 30A (the operation unit 31A).

When moving the top 10 upward, the user Q who has recognized the position of the operation unit 31A applies a forefinger Q1 or the like to the operation lever 37 of the operation unit 31A, as shown in FIG. When the operation lever 37 is moved from the neutral position P1 to the first movement position P2 with the index finger Q1 or the like, the pair of lifting mechanism units 23 extend and the top plate 10 moves upward (rises).
The neutral position P1 means a position where the lifting mechanism unit 23 is not extended or retracted (the top 10 is not moved in the Z-axis direction) even if the lifting control unit 40 detects the position of the operation lever 37.
When moving the top 10 downward, the control lever 37 is moved to the second movement position P3. Since the lever body 37a of the control lever 37 extends in the Z-axis direction, the user Q can also operate the control lever 37 in such a manner that the index finger Q1 etc. is hooked on the lever body 37a. By this operation, the pair of lifting mechanism units 23 contract, and the top 10 moves downward (drops).

  The user Q can operate the operation lever 37 of the operation unit 31A while monitoring the information on the elevation of the top 10 displayed on the display surface 32a of the display unit 32. Therefore, the user Q can adjust the height of the top 10 appropriately and easily.

The contact body T, which is another fixture or the foot of the user Q himself, may approach the operation unit 30A (the operation unit 31A) from below the top plate 10 without the user Q intending. As shown in FIG. 2A, the lower surface of the flange portion 34 located at the lower end of the operation unit 30A is disposed at a position flush with the lower surface 10b of the top plate 10 or above the lower surface 10b. Further, as shown in FIG. 3, the lower end portion of the operation lever 37 located at the lower end portion of the operation unit 30A is at any of the neutral position P1, the first movement position P2 and the second movement position P3. It is disposed at a position flush with the lower surface 10b of the top 10 or above the lower surface 10b. For this reason, when the contact member T which has moved upward from the lower side and approaches the operation unit 30A (operation unit 31A) contacts the operation unit 30A (operation unit 31A) or contacts the operation unit 30A (operation unit 31A) At the same time, it abuts on the lower surface 10 b of the top plate 10. Even when the user Q operates the operation lever 37 to move the top 10 downward, the contact member T contacts the operation unit 30A (the operation unit 31A) or the operation unit 30A (the operation unit 31A) before contacting. At the same time, the contact body T abuts on the lower surface 10 b of the top plate 10.
That is, the operation unit 30A (the operation unit 31A) is not pressed by the contact member T.

  As described above, according to the top-lifting-type desk 1 of the present embodiment, the contact unit T abuts on the lower surface 10 b of the top 10 to press the operation unit 30A (the operation unit 31A) by the contact T. Can be suppressed. Therefore, it is possible to prevent the lifting mechanism unit 23 from operating without the user Q's intention.

The operation unit 30A having the operation unit 31A is provided with a display unit 32 having a display surface 32a which is flush with the upper surface 10a of the top 10. Therefore, the user Q can recognize the position of the operation unit 30A (the operation unit 31A) at first glance. The display unit 32 does not protrude above the upper surface 10 a of the top 10, and the operation unit 30A does not narrow the work surface of the top 10.
Even when the table-lifting desk 1 is long in the X-axis direction, such as a meeting table, the user Q can recognize the position of the operation unit 30A (the operation unit 31A) at first glance, so that the operability Improve.

In addition, in the top-plate lifting-type desk 1 of this embodiment, it may replace with the operation unit 30A, and may be equipped with the operation unit 30B shown in FIG.2 (b).
The operation unit 31B in the operation unit 30B has an operation button 39 in place of the operation lever 37 as an operation member. Since the operation button 39 is disposed on the side of the operation unit 30B (the operation unit 31B), the user Q can access the operation button (operation member) 39 with the index finger Q1 etc. from the front of the operation unit 30B. . As in the case of raising and lowering the top 10 by the operation of the operation lever 37, the top 10 can be raised and lowered by the operation that the user Q presses the operation button 39. For example, the operation button 39 may be provided with a raising button for raising the top 10, a lowering button for lowering the top 10, a power button of the lifting mechanism unit 23, and the like.
The other configuration is the same as in the case of using the operation unit 30A. Therefore, even when the operation unit 30B is used, the same effect as described above is obtained.

Second Embodiment
Next, a second embodiment of the present invention will be described with reference to FIGS. 4 and 5. In the following description, the same reference numerals are assigned to components common to those described above, and redundant description will be omitted.
