Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a cantilever type lifting bed which is lifted and lowered by a pair of guide rails vertically installed on a wall surface.

[Problems to be Solved by Conventional Techniques and Inventions] Recently, with the modernization of life, an elevator bed that can be stored in the ceiling has come to be used in general households from the viewpoint of effective use of rooms. However, conventionally, this type of lifting bed has a structure in which the four corners of the bed frame are guided up and down by guide rails. However, of these four guide rails, two can be installed on the wall, but the remaining two cannot be installed on the wall. In such a case, the two guide rails cannot be installed. Since the rail is erected in the shape of a middle pillar, there is a problem in that the rail becomes an obstacle when storing the bed.

Therefore, it is proposed to suspend the bed frame in a cantilever manner, but in this case, it is necessary to make the cantilever support by the guide rail of the bed frame strong, and for that purpose it is necessary to provide a separate reinforcing member. It is necessary to do so and cannot be immediately adopted.

[Means for Solving the Problems] The present invention was devised with the object of providing an ascending / descending bed structure capable of eliminating these drawbacks in view of the above circumstances, and a pair of guide rails installed vertically. In addition, one side edge facing the guide rail of the bed pedestal is vertically movably supported, and a suspending body whose one end is connected to the protruding side end of the bed pedestal is passed from the upper end of the guide rail through the guide rail. Then, the bed pedestal is configured to be connected to a drive device incorporated in the bed pedestal, and the lifting and lowering of the bed pedestal is performed by the operation of winding and rewinding the suspension body by the drive device.

With this configuration, the present invention is capable of dispersing the load to the point of action while suspending the bed frame in a cantilever manner.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 is an elevating bed mount formed in a rectangular shape by a bottom plate 1b and four side frames 1a, and 2 is two guide rails that are installed opposite to a wall surface W. The support bracket 7 provided on one side edge of the bed pedestal 1 is slidably fitted on the outside, but the rail outer fitting portion 7a of the support bracket 7 is extended downward and the bed pedestal 1
Is taken into consideration so that the bed pedestal 1 can be lifted and lowered by a cantilever.

Reference numeral 3 denotes a suspension body made of a member such as a wire or a belt, the tip of which is connected to the upper edge of the corner of the side frame 1a on the projecting side of the bed frame 1 via a connecting tool 4. Is suspended by a pulley 2a provided at the upper end of the guide rail 2, and is arranged so as to pass through the inside of the guide rail 2 and reach downward. On the other hand, 5 is an electric drive device installed on the wall surface W side of the bed pedestal 1, in which the base end of the suspension body 3 arranged in the guide rail 2 is supported by the drive bracket 5.
Are connected to each other via the pulley 7b provided at the top of the guide rail 1, so that the bed mount 1 has four corners at the upper end of the pulley 2a at the upper end of the guide rail.
Each of them is suspended by a suspension body 3 in the form of being supported by, and thereby cantilever-supported. The bed base 1 is raised by winding the suspension 3 by driving the driving device 5, and is lowered by rewinding.

Reference numeral 6 is a winding drum of the suspension 3 provided in the drive device 5, and 7c is a guide roller provided at the upper and lower ends of the support bracket 7. The guide roller 7c rolls in contact with the guide rail 2. By doing so, the bed mount 1 can be smoothly moved up and down. In the figure, 8 is a guide rail 2
It is a stopper provided in the lower part of the inside.

In the embodiment of the present invention constructed as described above, the bed pedestal 1 is moved up and down by operating a switch such as a push button (not shown) to drive the drive device 5 in the forward and reverse directions, and the take-up drum 6
The bed pedestal 1 is cantilevered by a pair of guide rails 2 facing the wall. hand,
Since there is no guide rail on the projecting side, these guide rails on the projecting side do not get in the way.

As described above, in the present invention, the bed pedestal 1 is supported in a cantilever manner by the pair of guide rails 2 opposite to the wall surface W. The bed pedestal 1 is provided at the upper end of the guide rail 2. Further, the four corners are suspended and supported by the suspension body 3 which is supported by the pulley 2a and extends from this, so that even if it is cantilevered, the suspension body 3 can be firmly and reliably supported. Moreover, the suspension 3 is a member required for moving the bed frame 1 up and down, so that the member can be effectively used.

Of course, the present invention is not limited to the above-mentioned embodiment. For example, as shown in FIG. 3, the connection of the tip of the suspension body 3 to the corner of the bed base 1 on the projecting side of the bed base 1 is made. You may connect with the front-end | tip part of the connection tool 9 supported by the corner part overhanging side via the support shaft 9a so that rocking | fluctuation is possible.
Is urged toward the bed frame 1 side by the ammunition 10. In such a case, if the suspension 3 is further extended while the bed base 1 is lowered, the connecting tool 9 automatically falls due to its own weight and the urging force of the ammunition 10 and thereby the bed. During use, there is an advantage that the suspension 3 on the projecting side and the connecting tool 9 do not get in the way and can be made more excellent.
Moreover, when the connecting tool 9 falls down, the urging force of the ammunition 10 acts, so that when the bed is lowered, the suspension body 3 is maintained in a tension state until the connecting tool 9 completely falls down. At this point, the looseness detection switch (not shown) of the suspension 3 can be set to stop the drive unit 5 so that the bed mount 1 can be connected even after the bed mount 1 is lowered to the use position. This is convenient because the suspension 3 can be continuously fed out until the tool 9 falls down. In this case, when the bed is used, the connecting tool 9 is automatically laid down and overlapped and stored on the side frame 1a, so that the connecting tool 9 does not get in the way, and the appearance It has the advantage that the top is also smooth.

[Advantages] In short, since the present invention is configured as described above, the bed mount can be supported in a cantilever manner by the pair of guide rails, and the guide rail on the projecting side can be eliminated. The cantilevered bed pedestal is supported by a pulley provided at the upper end of the guide rail, and the four corners are hung and supported by the hung body in a form extending from this. Therefore, the bed pedestal has a structure in which it is supported at four points by the suspending body, and the guide rail can perform cantilever support, but can firmly and surely support it. In addition, since the suspension body that supports the bed mount at four points is a member necessary for raising and lowering the bed mount, there is also an advantage that the members can be commonly used.
