Description

Elevating apparatus

The present invention relates to a device that allows an object to be easily lifted and lowered by human force.

We often need to change the height of certain objects in our daily lives, or in industrial settings, for eye contact or storage.

According to the related art, a motor-driven device or a manual device using a gas spring has been used for this purpose. However, in the case of a motor-driven device, the manufacturing cost increases and there is a high risk of failure. Since it is impossible to optimize the elasticity of the weight of the object to be elevated, it is difficult to operate a person who is weak in force.

An object of the present invention is to provide a lifting device that can change the use weight according to the weight of the target object in the field to solve these shortcomings.

The present invention is attached to the slide rail (SR) is a shelf (SH) moving in a straight line, the rotating member (AX) to rotate while pushing up the shelf (SH), the gas spring (GS) for pushing up the rotating member (AX). And it consists of a tension spring (ES) for pulling the rotating member (AX) and a tension adjusting bolt (B) for adjusting the tension of the tension spring (ES).

The present invention is inexpensive and less trouble-free by using a power transmission device, so that the user can optimize the weight of the target object by using the gas spring (GS) and the tension spring (ES) in parallel to operate the target object with a small force. To be.

The principles, main parts, and embodiments of the present invention will be described with reference to the accompanying drawings.

Principle of the present invention is to install the elastic body having a constant force and the elastic adjustable in a position close to the rotation axis of the rotating body, by converting the force of the linear elastic body into a rotational motion and the rotational motion to a linear motion again By amplifying a long moving distance of the elastic body having a short moving distance, and by adjusting the rotational force of the rotating body by the elastic control of the elastic body to properly adjust the weight of the object to be used by the user to operate the lifting device with a small force.

The reason why the tension spring and the gas spring are used in parallel is as follows.

First, the tension spring is stretched and contracted, and there is a fluctuation like the ball bounces, and the tension force variation along the length is too large to obtain a constant tension force, but it is possible to adjust the tension force. In addition, the gas spring has a constant force, so the pressure cannot be adjusted, but it moves at a constant speed, there is no slack, and there is almost no variation in elasticity according to the compression distance.

Referring to the drawings of the computer desk monitor lifting device as an embodiment of the present invention the lifting device as shown in Figs.

The slide rail SR is fixed to the wall plate PB with a screw V1, and the shelf SH is fixed to the moving shelf fixing bracket RB of the slide rail SR with screws V2 and V3. In this structure, since the shelf SH is inclined forward or moved from side to side due to the play of the slide rail SR, the shelf supports SH1 and SH2 on which the guide rollers W1 and W2 are installed are fixed to the shelf SH to prevent this. When the three points are supported by the shelf fixing bracket (RB) and the two shelf supports (SH1 and SH2), the deflection and left and right clearance of the shelf (SH) are eliminated and the shelf (SH) is stable along the slide rail (SR). You will have a linear motion.

The rotating member AX is provided with a gas spring rotating shaft S1, a roller rotating shaft S2, a rotating shaft through hole H1, and a tension spring hook hole H2, and a roller W3 fitted with the roller rotating shaft S2. It is fixed by the snap ring (R4), the rotary shaft through hole (H1) is inserted into the rotating member bracket (B2) and fixed with a snap ring (R1) and then fixed to the wall plate (PB) with a screw (V8).

The lower end of the tension spring (ES) is hooked to the tension spring hook hole (H2) of the rotating member (AX), a nut (N) is inserted into the upper two or three nodes of the tension spring (ES), and the screw (V7) is attached to the wall plate (PB). Tighten the tension adjusting bolt (B) with the nut (N) by passing through the through hole of the bolt fixing bracket (B1) fixed with the).

Insert spacer SP and gas spring GS upper part in turn into gas spring rotation shaft S1 of rotating member AX, and fasten snap ring R2, and fix the lower part with screw V9 to wall plate PB. The gas spring bracket (B3) and tighten the snap ring (R3).

The purpose of the spacer SP is to prevent the gas spring GS from interfering with the rotation of the rotating member AX when the angle between the rotating member AX and the gas spring GS decreases due to the rotation of the rotating member AX. To prevent

For reference, FIG. 6 is a partially enlarged perspective view of the tension spring tension adjusting bolt B, and as shown in FIG. 7, there is a space between the wall plate PB and the shelf SH as much as the thickness of the slide rail SR. In the space, the rotating member AX is operated.

Front view showing the operation of the monitor (M) lifting device of the computer desk (D) to which the lifting device of the present invention is applied Referring to Figures 8 and 9 will be described the operation of each component as follows.

When pressing the top of the monitor (M) fixed to the shelf (SH) of the computer desk (D) with a bracket or screw, the shelf (SH) is lowered along the slide rail (SR), the rotary member pressed on the shelf (SH) AX) rotates and descends. At this time, the roller (W3) located on the bottom surface of the shelf (SH) rotates to minimize the friction between the shelf (SH) and the rotating member (AX) to smoothly lower the rotation of the rotating member (AX). As the rotary member AX pressed on the shelf SH rotates and descends, the gas spring GS is compressed and the tension spring ES is stretched to accumulate repulsive energy. When the monitor M is lowered below the computer desk D, the rotating member AX descends and rotates, and when the rotating member AX falls further beyond the horizontal, the rotating member AX and the gas spring GS are parallel to each other. Since the repulsive force of the gas spring (GS) is close to the rotation force applied to the rotating member (AX) is smaller so that the monitor (M) can be lowered with an increasingly smaller force. However, since the tension spring ES has a stronger tensile force as the rotating member AX rotates downward, the tension spring compensates for the elasticity of the gas spring GS that has fallen sharply, and is easily dragged with a small force when the monitor M is later raised. The tension is stored to raise.

When taking out the monitor (M), open the cover (C) of the computer desk (D), slightly lift the top of the monitor (M) to reduce the weight, the elasticity of the gas spring (GS) and the tension of the tension spring (ES) The rotating member AX rotates and lifts the shelf SH, and the user hardly feels the weight of the monitor M and can lift the monitor M. FIG. The monitor M, which has been raised, is maintained in an elevated state by the force of the gas spring GS and the tension spring ES.

At this time, when pressing the monitor (M), or if it rises on its own without maintaining the down state, loosen the tension adjusting bolt (B) to weaken the tension of the tension spring (ES), and if the pulling force is applied, the tension adjusting bolt What is necessary is just to tighten (B), and to adjust the tension of the tension spring ES strongly.

This makes it possible to maintain the stop state where the monitor M does not go down or rise by itself, and thus the monitor M is kept up or down without a separate locking device.

However, the present invention is not limited to the structure without the locking device, but using a variety of locking devices, by increasing or weakening the pressure of the gas spring (GS) and the tension force of the tension spring (ES), loosening the locking device automatically descending or rising It also includes use as a device.

11 is a view showing a partial perspective view and an operation path of the locking device installed on the lower lifting device in the lifting device of the present invention.

The locking device consists of a steel wire (WR) installed on the shelf (SH) and a steel wire guide (L) installed on the bottom, and when pressed and released with the descending, the steel wire (WR) is 1,2,3 at the point 0 of FIG. Pass point 4,5 to reach point P and lock it. If you press and release it again, it goes out of point P and rises past 6,7,8,9,10,0. When the locking device of the present invention is installed on the top, it may be installed upside down in the desired position.

In the present embodiment, the computer desk (D) is illustrated, but may be used as a lifting device for other objects such as a TV or various electronic products, and may be used as a device for storing up and down as well as for storing up and down. It can also be used as a device to stop at the desired height.

FIG. 10 is a front view showing an embodiment of a sink subject part for storing a microwave oven MO in the upper part. When the upper part is accommodated in the upper part, the tension spring ES is centered around the rotating member bracket B2 so as to easily adjust the tension force. It can be installed opposite to (GS) and the tension spring tensioning bolt fixing bracket (B1) can be installed on the lower side.

In order to use it as a lifting device for an object of completely different size and weight, the elasticity and length of the gas spring (GS) and the tension spring (ES), the length of the rotating member (AX) and the gas spring rotating shaft (S1) installed on the rotating member (AX) By changing the position and direction of the tension spring hanger hole H2, anyone can easily change the lifting distance and its force.
