JPH10312224A - Rotary elevating/lowering device for computer desk - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reduce the number of parts and to reduce a fault mode by connecting the lower part of an elevating/lowering case where a display and the like can put to a weight through a pulley, inserting a handle which cooperatively operates the gravity of the weight into a long hole over a panel board and sandwiching and fitting it. SOLUTION: The lower part of the elevating/lowering case 7 where the display and the like are put is connected to the weight 5 through the pulley 2. The weight 5 is set so that gravity becomes larger than that to which the gravity in a state where the display and the like are put in the elevating/ lowering case 7 at the time of a display user position. The handle 8 which cooperatively operates the gravity of the weight 5 is inserted into the long hole over the panel board 3 fitted to a desk main body 1. Since the gravity operation of the weight 5 is used and the principle is used, structure can be simplified and the number of parts can be reduced. The elevating/lowering case 7 can be elevated/lowered in the system of less fault model.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an improvement in the dead space of a computer and its peripheral devices. In order to use limited office space effectively, a desk and a computer are integrated. The present invention relates to a lifting device capable of storing a display of an OA device.

[0002]

2. Description of the Related Art Conventionally, when a computer is introduced into an office, the number of racks or desks increases by the number of offices, which takes up a place and is troublesome. Therefore, the computer desk aiming at integrating them and making effective use of the space has not been particularly easy to manufacture because of its complicated structure.

[0003]

When a computer is not used, a conventional computer desk has a lifting device capable of storing a display so that it can be used as an office desk. However, the structure is complicated and the cost is high. Or
Because of the large number of parts, the failure mode was high, and there was no device with a simple structure and low cost.

[0004]

Means for Solving the Problems The present invention solves the above problems and will be described below. In a device in which the display is rotated up and down,
B. Connected to a weight (5) via a pulley (2) from a lower portion of a lifting case (7) into which a display or the like enters. (C) forming long holes up and down in the panel plate (3) attached to the desk body (1); A rotary elevating and lowering device for a computer desk having the above-mentioned structure, in which a handle (8) interlocking with the weight of a weight (5) is inserted through a long hole through a panel plate (3) and attached with scissors.

[0005] The invention described below has a simpler structure when incorporated in the above contents.
Is the elevating case (7)
The weight was set to be slightly higher than when the weight with the display etc. was added to the.

[0006] The invention described below is an electric motor which is changed from manual to electric as described above so that it can be moved up and down more easily. Instead of the pulley (2), a combination of a gear (11) and a motor (9) is used. did.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION When using the present invention, hold the handle (8) by hand, lower it by lifting it up with the display etc. placed in the elevating case (7), and then raise it slightly (7) The weight distribution is dispersed with the display etc. placed in the car and the weight on the weight (5) decreases. Therefore, when the handle (8) is lowered halfway, the elevating case (7) automatically moves to the display use position. It rises and is fixed by the long hole of the panel plate (3) and the handle (8). On the other hand, when storing, the handle (8) is lifted up by hand and the display or the like is put in the elevating case (7). In this state, the weight distribution is balanced with the weight (5), and after that, the lifting case (7) automatically returns to the storage position of the lifting case (7). And it is fixed by the long hole of the panel plate (3) and the handle (8).

Embodiments of the present invention will be described below. As shown in FIG. 1, FIG. 2 and FIG. In a device in which the display is rotated up and down,
B. Connected to a weight (5) via a pulley (2) from a lower portion of a lifting case (7) into which a display or the like enters. (C) forming long holes up and down in the panel plate (3) attached to the desk body (1); The rotary lifting device of a computer desk with the above configuration, in which a handle (8) interlocking with the weight of the weight (5) is inserted through a long hole through the panel plate (3) and attached with scissors. Since the effect of weight is utilized well and the principle of leverage is used, the structure is simple and the number of parts is small, so that the lifting case (7) can be moved up and down by a system with few failure modes. Therefore, production can be performed at low cost without labor. In addition, because the whole system does not take up space, the foot can enter the desk and the space is secured, so that the function as a desk and a computer desk can be easily enjoyed.

When a string such as a wire rope is used as a means for connecting the lower part of the elevating case (7) into which the display enters to the weight (5) via the pulley (2), the apparatus operates with low sound. If it is used as a chain, it is robust, but the sound is a little noisy and requires maintenance such as refueling.

An L-shaped groove (4) is formed at the lower end of the long hole of the panel plate (3), or a hook-shaped groove (6) is formed at the upper end of the long hole. This serves as a stopper, and whether it is formed at the upper end or the lower end is determined by placing the display or the like in the elevating case (7) and making the weight (5) heavier than that. Or lighter. This is due to the difference in weight depending on the display, etc.
When attached to both lower ends, no subsequent maintenance is required.

In addition to the above system, the weight (5) is set so that the weight is slightly higher than the weight of the lifting case (7) with the display or the like put in at the time of using the display. did. This is to find out and use the balance between the weight change (5) and the weight change applied to the lifting case (7) by the action of the rotating shaft. This results in a simple structure with a small number of parts, and especially requires a stopper etc. And not. This leads to labor savings. In addition, if a cushion is attached to the desk body (1), the shock when the lifting case (7) is completely raised or lowered is almost eliminated.

As shown in FIG. 4, the pulley (2) is replaced with a gear (11) and a motor (9) to be electrically driven. In this case, the weight (5) is an auxiliary means, but the lifting case (7) can be moved up and down with a single switch. If the motor is a gear motor with a brake, the need for a gear box and a stopper is increased. Disappears. Therefore, handling becomes less troublesome, and the weight (5) is an auxiliary means, so that the amount of power consumption can be reduced.

[0013]

According to the present invention, the rotary lifting device of the computer desk makes good use of the weight function of the weight and is a system using the leverage principle. Therefore, the structure is simple, and therefore the number of parts can be reduced. And the system is inevitably reduced in failure mode. Therefore, the production can be performed at low cost without any trouble. In addition, because the whole system does not take up space, the foot can enter the desk and the space is secured, where the desk and computer desk can enjoy the original functions easily. As described above, the present invention has various effects.
