Description

STRAIGHTENING BED WITH AIRBAG {AIR BAG TYPE STRETCHING BED}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a stretching bed, and more particularly, to a stretching bed provided with an airbag for laying on a bed so as to exhibit an easy and simple stretching effect.

In general, beds are known to be one type of furniture made to sleep, but in recent years beds have emerged that can perform certain functions beyond simply taking a sleep.

The bed is used by putting a mattress on the upper side of the bed frame, and at this time, the bed frame is improved to perform a specific function.

Recently, a bed having various functions for health has been developed. For example, Patent Registration No. 0950162 discloses a technique related to a body stretching bed.

That is, in the above-described conventional technique, it is possible to perform stretching or waist movement using the driving means.

However, in the above-described prior art, since separate driving means and driving means for stretching are required to be mounted in the bed, it is difficult to move and install the bed, thereby increasing the cost of the product.

Disclosure of Invention Technical Problem [8] The present invention has been proposed in order to solve the problems of the prior art described above, and it is an object of the present invention to provide a bed structure in which stretching using an airbag can be efficiently performed, thereby reducing the cost of a bed and maximizing a stretching effect .

To achieve the above object, according to the present invention, there is provided a stretching bed comprising: an airbag which is formed inside a mattress and has a plurality of integrally connected structures; A compressor for filling air into each of the airbags; A controller for controlling the opening and closing of the valve so that the air to be filled from the compressor is selectively supplied to each of the airbags; A curved surface rail having a predetermined curvature at a lower portion of the airbag; And a stretch rod movable along the curved surface rail.

In addition, a sub-motor is mounted inside the stretching rod, a driving gear is formed on one side of the sub-motor, and a guide gear engaged with the driving gear is formed on the curved rail.

The bed of the present invention exhibits the effect of improving the stretching effect by simultaneously moving the stretching rod at the lower portion of the airbag together with the inflation force of the airbag.

Particularly, since the stretching rod is guided along the curved surface rail forming the curved surface shape, the stretching effect can be maximized.

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

1 to 5, a structure of a stretching bed having an air bag according to a first embodiment of the present invention will be described.

An airbag 20 is formed inside the mattress 10 that forms the outer shape of the bed. A plurality of airbags 20 are integrally connected to each other. A compressor 30 is connected and a valve 21 for opening and closing the flow passage is formed so that the air charged from the compressor 30 is selectively supplied to each airbag 20, The opening / closing control is performed by the control unit 40.

A curved rail 50 having a predetermined curvature is provided under the airbag 20, and a stretch rod 60 is movably provided on the curved rail 50.

In this case, a sub motor 61 is mounted in the stretching rod 60, a driving gear 62 is formed at one side of the sub motor 61, and a guide gear 52 are formed on the curved rail 50.

Hereinafter, the operation and effect of the stretching bed according to the present invention will be described.

First, in a normal state, the airbag 20 is not inflated and an appropriate air pressure is maintained. Thus, the mattress 10 is formed into a flat surface. In the case of performing stretching, the airbag 20 is inflated, (60) is moved.

At this time, the stretching rod 60 is gradually moved along the curved surface rail 50 by driving the sub motor 61, and the airbag 20 at the position where the stretching rod 60 is moved is sequentially expanded The air pressure is supplied from the compressor 30 so that the state shown in FIG. 6 is obtained.

Particularly, the expansion action of each of the airbags 20 is controlled by the control unit 40. By opening and closing the valve 21 of the airbag 20 under the control of the control unit 40, .

On the other hand, in order to shrink the inflated air bag 20, a separate air discharge valve (not shown) is provided at one side so that the control unit 40 controls opening and closing.

Accordingly, it can be seen that the stretching bed of the present invention maximizes the stretching effect, because the stretching force of the airbag 20 and the action of the stretching rod 60 are simultaneously performed.

In addition, in the region where the curved rail 50 has a descended shape, stretching is performed only by the inflation force of the airbag 20 without the influence of the stretching rod 60.

7 and 8 show a structure according to a second embodiment of the present invention. A supporting wire net 70 for stably supporting the airbag 20 is formed in the inside of the mattress 10, A protective pad 80 for preventing direct contact with the stretching rod 60 is formed under the protection pad 80 and a thin Teflon film 80 for minimizing the frictional force with the stretching rod 60 81 are attached.

As shown in FIG. 8, the airbag 20 is divided into a plurality of spaces by bellows-shaped partitions 22 so that the height of the airbag 20 can be easily adjusted. Inside the partitions 22, (23) is preferably provided.

This structure allows the airbag 20 to be supported by the support wire net 70 so that the sagging phenomenon due to the upper load can be prevented. The stretching rod 60 is supported by the protection pad 80 The direct contact with the wire mesh 70 is prevented, so that smooth movement can be achieved.

Particularly, since the Teflon film 81, which is a lubricating material, is attached to the bottom surface of the protective pad 80, the frictional force with the stretching rod 60 is minimized and the stretching rod 60 is more effectively moved along the curved surface rail 50 It can be seen that.

When the partition wall 22 has a bellows shape and a resilient spring 23 is built in the partition wall 22, the inflating action of the air bag 20 due to the supply of air pressure from the compressor 30, So that the stretching effect can be maximized. In the contraction operation, the elastic spring 23 makes it possible to perform a quick restoration operation.

Although specific embodiments of the present invention have been described and illustrated above, it is to be understood that the stretch bed structure of the present invention can be variously modified by those skilled in the art.

It should be understood, however, that such modified embodiments are not to be understood individually from the spirit and scope of the invention, and such modified embodiments are intended to be included within the scope of the appended claims.
