Description

[Detailed explanation of the invention] [Field of industrial application] This invention lowers the bed from above along the guide rail when the bed is in use, and raises the bed along the guide rail when the bed is not in use. This invention relates to an elevating bed that can be stored on a surface.

[Conventional technology]

Due to the housing situation in Japan, the floor space per person is still insufficient compared to Western countries.
The reality is that there is no promising material for the future. Due to the above-mentioned circumstances, the idea of upward movement naturally emerged as an effective use of floor space. In condominiums, especially one-room condominiums and dormitories for singles, due to the above-mentioned circumstances, beds that occupy a large amount of floor space are installed as fixed beds or movable beds as shown below.

As shown in FIG. 10, the above-mentioned conventional fixed bed has a bed floor 54 horizontally protruding not from the floor 51 but from a side wall 53 near a ceiling 52 with a slightly raised ceiling. Bed mats and futons were laid on the floor 54 to make a bed. Since the fixed bed 55 is located at a height of about 2 m from the floor 51, a ladder 56 for climbing up and down is permanently installed.

Furthermore, as a conventional example of a movable bed, there is a type that can be stored in a side wall. When the bed is not in use, it can be rotated 90 degrees toward the wall using one side of the bed as a fulcrum, and the bottom of the bed can be stored as part of the wall.When the bed is in use, the bed can be rotated 90 degrees from the wall side, contrary to the above. It is used by pulling it down.

[Problem that the invention attempts to solve]

The above conventional technology has the following problems.

(A) Regarding fixed beds a. The bed is located high, making it difficult to climb up and down using a ladder.

b The space from the bed to the ceiling is narrow, creating a feeling of mental pressure.

c. Since the ladder is permanently installed, it not only becomes a nuisance, but also becomes an obstacle when installing furniture and luggage.

d. Because the bed is always visible, it is unsightly when guests come to visit, and women in particular take measures such as covering their eyes with blinds.

e The indoor ceiling height will be higher than normal construction, so special consideration must be given to the structure of the building.

(B) About the movable bed a The bed is stored upright against the side wall, so
The bedding will be pushed to one side.

b The side wall that houses the bed needs to be thicker than normal construction.

This invention solves the above problems and provides an elevating bed in which the bed frame lowers horizontally along the guide rail when the bed is in use, and raises the bed frame horizontally and stores it on the ceiling surface when the bed is not in use. The purpose is to

[Means for solving problems]

This invention was constructed as follows as a means to solve the above problems.

That is, separate guide rails are provided vertically on the outside of the opposing side plates of the bed frame, and suspension supports equipped with rotating supports are projected at positions corresponding to the side plates of the bed frame corresponding to the guide rails. One end of the suspension member for suspending the bed frame is fixed to the upper part of the guide rail, and the other end is attached to the bed via the rotating support. A balancer is connected to the joint part via a support roller pivotally supported on a pedestal frame, and further has a balancer having an output substantially equal to the bed's own weight, and is connected to the joint part in a direction in which the suspended material is pulled.
The elevating bed is characterized by maintaining the balance of the bed frame.

[Effect]

According to the elevating bed of this invention, one end of the bed frame is fixed to the upper part of the guide rail, and the other end is attached to the joint part via a rotating support and a support roller that is pivotally supported on the bed frame. The bed is suspended by a connected suspension member, and the balance of the bed frame is maintained by a balancer having an output approximately equal to the weight of the bed connected to the joint portion in the direction in which the suspension member is constantly pulled. Then, when the bed frame is moved up and down along the guide rail, the joint part pulls in and sends out the suspended material by the constant output of the balancer, so that all the suspended materials are moved by the same distance. The bed frame is raised and lowered while being horizontally balanced while guiding the suspension support to the guide rail.

While maintaining the protruding length of a and 38b constant, the protrusion of the rotation pin 41b allows the connection plate 3 to
7' and 37 are limited, and the latch bar 38
The retracted lengths of c, 38d, 38a, and 38b are maintained constant.

The above latch bars 38a, 38b, 38c, 38
As shown in Fig. 2, the protruding position of d is on the inside close to the guide rail B that is parallel to the indoor wall D, so that the upper and lower limit positions of the bed frame C are located inside the guide rail B. The latch hooks 42 that hang on the latch bars 38a, 38b, 38c, and 38d are attached. As shown in FIG. 6, the latch hook 42 is installed by lifting the bed frame C and placing it at a position corresponding to the upper limit of the guide rail B.
L-shaped latches 42 are attached in a V-shape at four identical positions on the opposing guide rails on one side and the other side, with the tips of the inclined parts 43 facing upward. Then, the protruding tips of the latch bars 38c and 38d move upward from below the latch hook 42, retract by the stroke of the undulation that makes sliding contact with the slope part 43, and when they cross the slope part 43, the action of the spring 40 , latch bars 38c, 38d again
protrudes and suppresses the downward movement of the bed frame C. Although not shown, the bed frame C is lowered to a position corresponding to the lower limit of the guide rail B, and the latches 42 are placed at four identical positions on the guide rail B at positions corresponding to the abutment of the stopper 5. On the contrary, by attaching it in an inverted V shape so that the tip of the inclined part 43 faces downward, it becomes a lock when the bed frame C is lowered to the lower limit and fixed. In this case as well, each latch bar is engaged with the latch hook 42 and locked simply by lowering the bed frame C. To release the lock mechanism F, the lock levers 38a, 38b, 38c, 38d are rotated by rotating the lock lever 35.
Since this moves in the retracting direction, the bed frame C can be raised or lowered in this state.

As shown in FIGS. 1, 2, and 6, the bed frame C has a balancer spring 3 on the entire upper surface.
A floor plate 44 covering the mechanical parts such as No. 4 is stretched on which a futon or the like can be laid, and a bottom plate 45 is stretched on the lower surface. If this bottom plate 45 is made the same color as the ceiling, it will not be noticeable even if the bed frame C is raised and stored on the ceiling.

In addition, as shown in FIG. 1, side plates 7, 7', 8,
A safety handrail 46 is attached to the upper part of each bed frame C, and a handle 47 is attached near the middle of the bottom plate 45 of the bed frame C in parallel with the short side plates 7 and 7'.
It is used as a handle for raising and lowering the bed frame C.

The operating principle of the elevating bed according to the above embodiment will be explained based on FIG. 8.

As described above, the bed frame C is loaded with the weight W which includes not only its own weight but also the weight of the mechanical parts and the bedclothes. Then, in order to divide the bed weight W into four equal parts and suspend it on the four wires 21, 21a, 21b, 21c, and 21d, the joint part G is
is connected to. Furthermore, balancer spring 3
Balancer wire 34' unwound from 4, 34,
Since 34' is connected to the joint part G,
The bed frame C is held balanced in a horizontal position.

When the bed frame C in the above state is raised, the balancer spring 3 pulling the joint part G
4 and 34 move the joint part G in the direction of the arrow Y, so that the wires 21a, 21b, 21
c and 21d are pulled by an equal distance from each other, and the bed frame C rises with a light force while maintaining horizontal balance. Also, when the bed frame C is lowered,
Contrary to the above, since the joint part G moves in the direction of arrow Z, the wires 21a, 21b, 21c, 21
d are sent out an equal distance from each other, and are lowered with a light force while keeping the bed frame C horizontally balanced.

In this example, the guide rails were attached to the opposing surfaces of the indoor walls, but this can also be applied even if one of the indoor walls is missing. In this case, the two guide rails on one side can be attached from the ceiling to the floor. It can be installed upright.

[Effect of idea]

Since this invention is constructed as described above, it has the following effects.

a. The bed frame is guided by guide rails and moves up and down, so when the bed is used, it can be used as a bed immediately by lowering it, and there is no need to go up and down a ladder.

b When using the bed according to a above, there is sufficient space up to the ceiling and there is no feeling of mental pressure.

c. By adjusting the lower limit position of the bed frame to an appropriate intermediate height, desks, luggage, etc. can be installed in the space between that position and the floor, making it possible to make effective use of the space.

d When the bed is not in use, the bed frame can be raised and stored on the ceiling, so the bed is not noticeable.
It doesn't look unsightly even when you have guests over.

e It can be installed inside an existing residential building without requiring any special construction such as raising the ceiling height or thickening the side walls.

f Since the balancer is fixedly installed and connected to the joint part, the hanging material connected to this joint part can be varied by an equal distance, and the bed frame can be raised and lowered with a small amount of force.
Since the bed frame can be raised and lowered while maintaining horizontal balance, the futon does not shift to one side.
