Bed Lifts {A UP AND DOWN ASSEMBLY OF BED}

The present invention relates to a device for elevating a bed, and more particularly, to easily adjust the height of a bed by providing an elevating device that is electrically operated.

In general, the bed used for body massage or medical care for beauty is to be able to improve the use by being able to adjust the height.

However, in the related art, the conventional method was a structure in which the height of the support leg can be manually adjusted in order to raise or lower the height of the bed. Caused inconvenience.

In addition, a lift device composed of a pneumatic cylinder and a pneumatic pump has been conventionally used to more easily adjust the height of the bed. However, in the case of such a pneumatically actuated structure, air must be periodically injected and used for discontinuous pump operation during the lift operation. Due to the vibration is transmitted to the bed did not achieve a comfortable operation, there was a problem in use.

Therefore, the present invention has been proposed to solve the problems of the prior art, by providing an X-type parallel stretching mechanism to raise and lower the bed by using the motor power to achieve a stable height adjustment of the bed according to the user's operation The purpose is to help.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a perspective view of the frame of the elevator apparatus of the present invention, Figure 2 is an enlarged view of the power unit for driving the elevator, Figure 3 is a view showing an operating state according to an embodiment of the present invention, Figure 4 is another embodiment The configuration and operation state diagram of the lifting device according to the present invention are shown.

First, as shown in Figures 1 to 3 will be described the overall configuration of the beauty bed having a lifting device of the present embodiment.

As shown in FIG. 1, a base 3, which is a bottom surface, is fixed below the table 2 on which the bed mattress 1 is to be seated, and a pair of links 4 and 5 intersect with each other between them. An X-shaped parallel telescopic mechanism for supporting (6) is mounted and supported.

The first link 4 of the X-type parallel stretching mechanism pivotally pivots the upper end 4a to the table 2, axially supports the roller 7 at the lower end thereof, and rails at the base 3 thereof. (8) is installed to free up perturbation. On the contrary, the second link 5 pivotally pivots the lower end 5a to the base 3, axially supports the roller 9 on the upper end, and also installs a rail 10 to free up perturbation. .

The lower end of the second link 5 is provided with a motor driver 11 in which a high quality motor 12 implementing low noise is installed, and an operating rod 13 linearly moving at one end of the motor driver 11. ) Is hinged (15) to allow rotation of the first link (4). The cylinder rod 16 is coupled to a predetermined upper portion of the second link 5 to receive the support of the cylinder 17.

As shown in the cutaway view of FIG. 2, the motor driving body 11 is formed of internal components such as a worm gear 11a, a bearing 11b, an elastic spring 11c, and rotates from the motor 12. The power is changed to the linear power of the operating rod 13 to be transmitted, and other detailed component parts and detailed operation descriptions of the respective parts are not related to the gist of the present invention and will be omitted.

In the figure, reference numeral 21 denotes a bellows to mask the external appearance of the elevating device structure under the bed.

Hereinafter will be described the operation of the lifting apparatus according to the embodiment.

In this embodiment, the massage bed is shown as an example, and the massage experienced person is in a position lying on the bed mattress (1).

Then, in the state where the height of the bed mattress 1 is lowered, the operator applies a control signal to the motor driving body 11 by pressing a separate control button for raising the bed.

That is, when the motor 12 is rotated forward as power is applied, the operating rod 13, which receives power through each component inside the motor driver 11, gradually extends and is hinged 15. When the first link 4 is pushed, and the stretching force is transmitted to the second link 5, the bed mattress 1 gradually rises as the links 4 and 5 on both sides rotate about the intersection point 6 as the central axis. Done.

When the bed mattress 1 rises to a desired height, when the stop signal is applied, the pair of links 4 and 5 maintain the standing state while the motor 12 stops operating. .

The height and position of the bed can be easily controlled according to the operation of the lifting device, and each power source is made by the driving of the motor to achieve a more stable operation.

On the other hand, the home position operation of the bed, which has been raised as described above, is made while the operation rod 13 is gradually pulled in accordance with the reverse rotation of the motor 12 according to the control signal, wherein the cylinder 17 mounted on the base 3 is ) To achieve a stable descent.

That is, according to the operation of the operating rod 13, the first link 4 and the second link 5 are lowered again at the intersection 6 with the central axis, wherein the cylinder rod 16 is the second link 5 Since it is coupled to the upper end, the cylinder 17 supports the sudden fall of the bed by its own load, thereby preventing the impact of the masseuse lying on the bed.

This, the buffering effect of the cylinder 17 can act even when the bed rises to have an effect.

In addition, the extension of the operating rod 13 in accordance with the rotation of the motor 12 is made to be stable and continuous to show the advantage that the lifting of the bed mattress (1) at a constant speed.

And, a, b, c of Figure 4 shows the configuration and operation of the massage bed according to another embodiment of the present invention, in addition to the structure of the embodiment is a folding structure is added.

That is, as shown in FIG. 4A, a folding table 2 ', which is supported by a hinge hinge 18 at a predetermined angle, is integrally provided on one side of the table 2, and a bed mattress 1' is provided. At the bottom of the folding table (2 ') is seated is a motor driver for folding (19) is installed so that the operation rod 20 is coupled to the table (2') is installed.

In the state configured as described above, when the bed mattress 1, 1 'is to be raised, it is operated by the motor driving body 11 in the same manner as in the above embodiment, and the elevated state is shown in FIG. 4B.

In this state, when the upper body of the massaging person lying on the bed mattress 1, 1 ′ is to be raised at a predetermined angle, the folding table 2 ′ supported by the hinge hinge 18 is rotated. do.

The folding table 2 'is made to flow by the operation of the folding motor driver 19, which forms a power source and an internal configuration with the motor driving member 11 and according to the extension of the operating rod 20. It can be seen that it is possible to easily adjust the folding angle as shown in Figure 4c.

Therefore, it is possible to further improve the utilization efficiency of the bed in addition to the lifting structure in one embodiment.

The overall operation of the lifting device of the present invention made in this way is made by a control using a separate switch means (not shown), and the switch means is preferably provided as a foot switch or a button type on the side of the table 2 using the foot. Do.

And while the specific embodiment of the present invention has been described above, it is obvious that the bed lifting apparatus of the present invention may be variously modified and implemented by those skilled in the art.

For example, it can be expected that the application can be applied not only to the beauty of the embodiment but also to medical use.

However, such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments shall fall within the appended claims of the present invention.

Bed lift apparatus of the present invention as described above, by applying an X-type parallel stretching structure that can achieve structural stability exhibits the effect that the height of the bed can be easily adjusted.

In addition, there is an advantage that low noise during operation can be realized by employing a high quality motor driver as a power source for lifting.
