DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table with a table top raising / lowering mechanism for raising and lowering a table top by the driving force of a motor.

[0002]

2. Description of the Related Art There is a table with a top plate elevating mechanism configured to be able to raise and lower a top plate so that OA equipment and the like mounted on the top plate can be adjusted to a height position suitable for an operator. If the device is used by many people with different heights and sitting heights without being specified, it is necessary to configure the top plate to be driven up and down by the driving force of the motor so that the height can be adjusted to an appropriate height by a simple operation. is there.

[0003]

In such a table with a top plate elevating mechanism, an input operation device such as a keyboard is arranged on the near side, and a display device such as a CRT is arranged on the back side. If the height can be adjusted separately, the working posture of the operator can be made more appropriate, so that the usability is improved and the degree of fatigue is reduced, thereby improving the working efficiency. For this purpose, it is sufficient to divide the top plate back and forth, and to make them both vertically movable independently.In this case, a motor for driving the front top plate up and down is provided near the front top plate. When it arrange | positions, the problem that a foot space becomes narrow and workability | operativity is impaired arises.

SUMMARY OF THE INVENTION The present invention solves such a problem, and a table with a top plate elevating mechanism configured to prevent a foot space from being narrowed by a motor for driving a front top portion to move up and down. It has been devised for the purpose of providing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 shows a table with a top plate elevating mechanism constructed according to the present invention. In this table, an input operation device such as a keyboard is mounted on a front top 1 and a display device such as a CRT is mounted on a rear top 2. A pair of left and right side plates 5.6 are provided on each of the left and right sides and support the legs 3.4 so as to be able to move up and down, and upper and lower shelves 7.8 provided below the rear top plate 2. In addition, they are connected and fixed to each other by a partition plate 9.

In this table, as shown in FIG. 2, a front top plate for driving the front top plate portion 1 up and down so that the front and rear top plate portions 1 and 2 can be raised and lowered independently of each other. A top motor 11 is arranged on the upper surface of the upper shelf plate 7, and a rear top motor 11 for moving the rear top plate 2 up and down is arranged on the lower surface of the rear top plate 2. The rear top 2 can be moved up and down to a greater extent than the front top 1. Both motors 10 for the front top plate and the rear top plate
Numerals 11 are provided at the opposite left and right ends, respectively, in order to avoid interference between the two when the rear top plate 2 is lowered.

As shown in detail in FIG. 3, a shaft 12 is provided above the upper shelf plate 7 in the left-right direction so as to extend between left and right side plate portions 5 and 6. A gear box 13 in which gears for transmitting the driving force of the front top plate motor 10 are built in is provided with the front top plate motor 10. The shaft 12 is formed by connecting a pair of bar members via a coupling 14 so that they cannot rotate relative to each other, and bevel gears 15 are provided at left and right ends thereof.

As shown in FIG. 2, the bevel gear 15 of the shaft 12 meshes with a bevel gear 17 provided at the upper end of a threaded bar 16 arranged vertically in the side plates 5 and 6. , The rotational movement of the shaft 12 is converted into the rotational movement of the screw rod 16. The upper part of the bevel gear 17 of the screw rod 16 is rotatably supported by a stay 18 which is vertically provided to pivotally support the end of the shaft 12. On the other hand, the lower end of the threaded rod 16 is screwed into a center hole of a slider 21 slidable in the vertical direction along a slit 20 formed in the guide plate 19. 21 moves up and down.

One end of an arm 22 as a swinging member pivotally supported at an intermediate portion by a guide plate 19 is pivotally attached to the slider 21. The other end of the arm 22 is pivotally attached to a bracket 23 fixed to the leg 3,
When the arm moves up and down, the arm 22 swings and the bracket 23 moves up and down in the direction opposite to the slider 21, and accordingly, the leg 3 moves up and down along the guide tube 24 to move the front top 1
Performs a lifting operation.

As described above, the front top plate 1 is driven up and down by transmitting the vertical movement of the slider 21 which operates in response to the rotation of the screw rod 16 to the leg 3 via the arm 22. The rear top plate 2 is driven up and down by a different mechanism. That is, the lower end of the threaded rod 25 hanging down from the lower surface of the rear top plate 2 is connected to the sheath tube 2 in which the internal thread is threaded.
6, and when the screw rod 25 rotates, the side plate 5
The screw rod 25 itself is displaced up and down with respect to the sheath tube 26 fixed to 6, and the leg 4 correspondingly moves the guide cylinder 29.
, And the rear top plate 2 moves up and down.

On the other hand, the mechanism for rotating the screw rod 25 by the driving force of the rear top plate motor 11 is the same as that of the front top plate motor 10 described above. Is rotated by the rear top plate motor 11 via a gear box 28, and the rotational movement of the shaft 27 is converted into the rotational movement of the screw rod 25 via a bevel gear. I have.

[0016]

As described above, according to the present invention, it is possible to prevent the foot space from being narrowed by the motor for driving the front top plate up and down, thereby improving the usability and reducing the work efficiency of the user. A great effect can be obtained for improvement.
