Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a manual cantilever lifting bed.

[Conventional technology]

BACKGROUND ART There is known a lift bed that enables utilization of space by lowering it when it is used and raising it when it is not used.

According to this, the guide rails for raising and lowering are installed upright at the four corners of the bed body, and the hanging wires housed in the respective guide rails are automatically wound by the motor-driven winding device installed in the bed body. It is said that the bed is an electric one that can be moved up and down and is of a stationary type.

[Problems to be solved by the device]

However, in this case, since it is an electric type, it becomes relatively expensive by incorporating a motor and a winding device in the bed body, and it is a stationary type that uses guide rails at the four corners. For example, even if two of these guide rails can be erected near the wall surface in the room,
The guide rail of the book is always fixedly erected at an intermediate position in the room according to the size of the bed body, not only spoiling the appearance but also restricting the indoor space when not in use due to the bed body rising. Will hinder the use of.

The present invention has been made in view of such circumstances, and the problem to be solved is to use it for a manual operation, which can be relatively low in cost, and enable it to be lifted and lowered as lightly as possible. It is intended to provide a manual cantilever lifting bed that can effectively use the indoor space without requiring a guide rail that sometimes obstructs the use of the indoor space.

[Means for Solving the Problems]

In view of the above problems, the present invention has a pair of guide rails to be embedded in a wall or to be attached to a wall, and a pair of bed brackets can be lifted and lowered to prevent the bed rails from falling on the pair of guide rails. The bed main body is supported in a cantilever manner, while the bed bracket is provided with a pair of balancers so as to offset the load of the bed main body. A pair of channel-shaped vertical guide rails with a wall, and a vertically movable member that is vertically movable via rolling members or sliding members that are in close contact with the front and rear and left and right inner walls of the channel-shaped vertical guide rails A pair of bed brackets that are arranged so as to project inward,
A bed main body supported by a pair of bed brackets on the indoor side of the channel-shaped vertical guide rails in a cantilever manner, and a pair of balancers chain-connected or wire-connected to the pair of bed brackets so that the bed main body can be manually raised and lowered. The present invention relates to a manual cantilever lifting bed characterized by comprising: and this is the means for solving the above problems as the gist of the invention.

In the present invention, the term "close contact" means that the relationship between the bed bracket and the guide rail does not change even with respect to the bending moment acting on the bed bracket, so that the bed bracket does not roll or roll tightly. Used for the meaning of sliding contact.

〔Example〕

The present invention will be described in more detail with reference to the drawings showing the following examples. 1 is a manual cantilever lift bed, 2 is a bed body, and 9 is a bed body.
Is a vertical guide rail, 13 is a bed bracket, and 23 is a balancer.

In the lifting bed 1 of this example, the bed body 2 is cantilevered up and down on the pair of vertical guide rails 9 via the pair of bed brackets 13, while the load of the bed body 2 is offset by the pair of balancers 23. As it is obtained, it is manually moved up and down as lightly as possible.

The bed main body 2 includes a frame 3, a finish bottom plate 4 such as a steel plate stretched on the lower surface of the frame 3, a rising wall 5 that surrounds the frame 3 up and down on four sides, and a latch (not shown) before and after the rising wall 5. Pipe guard 6 that can be tilted freely
With, for example, a length of 2,000 to 2,100 mm and a protrusion width of 1,0
It is supposed to have a height of 00 mm and a height of 100 mm.

The vertical guide rails 9 are constructed as a pair of channel-shaped channels with walls each having a slide groove 11 between left and right facing flanges 10. For example, a thick steel plate with a thickness of 2 to 3 mm spans between the ceiling and the floor surface of 2,500. It is an integral long piece with a length of ~ 2,800 mm.

In this example, a hollow balancer guide having a rectangular cross section is formed on the facing surface side of each of the vertical guide rails 9 and is made of the same thick steel plate as the vertical guide rails.
The vertical guide rails 9 provided with the balancer guides 12 are embedded in the concrete wall A so as to be flush with the wall surface and fixed parallel to each other at predetermined intervals. It is attached to the wall.

This embedding fixation is performed by, for example, installing a plurality of screw anchors (not shown) in the longitudinal direction on the concrete wall A, and screwing the screws into the through holes in the bottom wall of each vertical guide rail 9.

The bed bracket 13 is a rolling member 17, 18 that is in close contact with the front and rear inner walls and the left and right inner walls of the channel-shaped vertical guide rail 9.
Assuming that the bed main body 2 is cantilevered on the indoor side of the channel-shaped vertical guide rail 9 while being vertically movable via the slide groove 11 and protruding from the slide groove 11 to the indoor side. is there.

That is, in this example, the pair of bed brackets 13 are made into a plane T-shape integrally by the base portion 14 in the vertical guide rail 9 and the support portion 15 protruding from the slide groove 11, respectively,
For example, it is made of thick steel with a thickness of 6 mm, and
4 has three notches on both sides in the vertical direction,
A roller fixing plate 16 is attached to each of the cut-off portions.
14 is projected in the direction orthogonal to 14 and these roller fixing plates 16 are
As the front and rear rolling members 17, a pair of front and rear hard rollers made of hard nylon are fixed at a total of 6 positions, while the base portion 14 is used.
On both sides of the roller fixing plate 16 in the vicinity thereof, three hard nylon rollers of the same type are axially fixed as the left and right rolling members 18 in a laterally projecting manner at three locations each.

The rolling members 17, 18 made of these rollers are installed with high accuracy so that their outer dimensions are equal to the front-rear inner dimension and the left-right inner dimension on the inner wall of the vertical guide rail 9, and by this The moving members 17 and 18 are in close contact with the bottom wall forming the inner wall of the vertical guide rail 9 and the back surface of the flange 10 and the left and right inner walls at three positions in the vertical direction so that the bed bracket 9 can be vertically moved. is there.

On the other hand, the support portion 15 of the bed bracket 9 has the slide groove 11
From the inside to the both sides of the rising wall 5 of the bed main body 2 and fixed to the bed main body 2 by bolting to the rising wall 5 at a position near the concrete wall A. The bed body 2 is supported horizontally and firmly on the concrete wall A side as much as possible.

Further, the pair of bed brackets 9 are arranged so that the bed main body 2 can be manually raised and lowered, that is, the load of the bed main body 2 can be canceled and the manual movement of the bed bracket 2 can be performed as lightly as possible. Chain to each balancer 23
22 connected.

That is, in the bed bracket 9 of this example, one end of the chain 22 is fixed to the upper end of the base portion 14, while the chain 22 is wound around the sprocket 21 mounted and fixed between the vertical guide rail 9 and the balancer guide 10. The direction is changed, and the other end is fixed to the upper end of the balancer 23 that can be raised and lowered in the balancer guide 10.

In the figure, 20 is a wire 8 for the release device 7 on the bed body 2 side.
The locking device used in this example is connected to and disengageable from the locking member 19 provided at the lower position of each vertical guide rail 9. The bed main body 2 is locked by spontaneously locking it, and when the bed main body 2 is raised, the release device 7 is operated by falling the front pipe guard 6 and the lock device 20 is pulled by pulling the wire 8. The lock can be released elastically.

In addition, numeral 24 in the figure is installed by suspending it on the indoor side of the vertical guide rail 9 on one side, and by operating the operation chain 25, the gear 26 coaxial with the sprocket 21 on one side is rotated and the bed body 2
The lifting and lowering operation device also used in this example in order to raise and lower the device by the operation chain 25 is shown.

In this example, the total load of the bed body 2 and the mattresses, futons, etc. used when using the bed body 2 is, for example, maximum.
While the balancer 23 is assumed to be 55 kg, each 30 kg
Since, for example, the total of 60 kg is set, the bed body 2 is more than the assumed load of the bed body 2 is offset.
Is automatically lifted when the lock device 20 is released due to a load difference of 5 kg. By operating the operation chain 25 and applying a force of 5 kg, the bed body 2 is lowered as lightly as possible. This made it possible to make it extremely suitable as a manual cantilever lifting bed.

Although the illustrated example is as described above, the rolling member is a bearing, and instead of the rolling member, a sliding member that reduces frictional resistance as much as possible is used. Use a wire instead of a chain to connect the balancer with the balancer, and use a rotating wheel or other guide instead of the sprocket.
In implementing the present invention, including the L-shaped cross section of the balancer guide, omitting the installation of the balancer guide, and using the vertical guide rail for directly mounting on the wall surface, etc. , The specific material, shape, structure, number, dimensions of these rolling members or sliding members, bed brackets, bed main bodies, balancers, their relations, and their additions, etc., are changed unless they contradict the gist of the above invention. However, the present invention is not limited to those illustrated and described above.
