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 relates to an elevating bed that can be stored on the side.

[Conventional technology]

Due to the housing situation in Japan, the floor space per person is still not enough compared to Western countries, and the reality is that there is no material that can be expected for the future. Due to the above-mentioned circumstances, the idea of upward movement naturally emerged as an effective use of floor space. And Mansion,
Particularly in one-rule condominiums and dormitories for singles, etc., due to the above-mentioned circumstances, beds that occupy a large amount of floor space are installed as either fixed beds or movable beds as shown below.

As shown in FIG. 8, the above-mentioned conventional fixed bed has a bed floor 54 that protrudes horizontally 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. This fixed bed 55 is located at a height of approximately 2 m from the floor 51, so a ladder 56 for climbing and descending is required.
was 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 rotates 90 degrees to the side wall using one side of the bed as a fulcrum.
The bottom of the bed is stored as part of the wall surface, and when the bed is used, the bed is turned 90 degrees from the wall side and pulled down, contrary to the above.

[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 and there is 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, and special consideration will need to 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 thickness of the side wall that accommodates the bed needs to be thicker than normal.

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 when 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 both opposing sides of the bed mount, and a suspension support portion including a rotating support is protruded from a position corresponding to the guide rail on the bed mount. At the same time, one end of the suspension material is fixed to the upper part of the guide rail, and the other end is attached to the center of the bed frame via the rotation support of the suspension support section. The suspended material is wound around a take-up shaft which is pivotally supported by the bed frame and winds it up with an even load.Furthermore, a constant output is constantly applied to the wind-up shaft inside the bed frame to tension the suspended material and balance the bed frame. It consists of an elevating bed equipped with a balancer that holds the

[Effect]

According to the elevating bed of this invention, one end of the bed frame is connected to the upper part of the guide rail, and the other end is wound around the winding shaft which is pivotally supported in the center of the bed frame via a suspension support. Since it is suspended by rotating hanging materials, an equal load is applied to all the hanging materials. Furthermore, the balancer installed inside the bed frame constantly provides a constant output to the take-up shaft, which tensions the hanging material to maintain the balance of the bed frame, allowing the bed frame to be raised and lowered smoothly with a light force. can be done. Then, by moving the bed frame up and down along the guide rail, the constant output of the balancer moves the suspension support part while winding up or unwinding the other end of the suspension material wound around the winding shaft. Guided by the guide rails, the bed frame rises and falls horizontally.

A first winding drum 30 and a second winding drum 31 are fitted near the middle of the winding shaft 21,
It is rotatable integrally with the winding shaft 21. A first balancer spring 32 and a second balancer spring 33 are fixed inside the short side plates 7, 7', respectively. The first balancer spring 32 causes the unwound wire 32a to pass through a folding roller 34a provided on the left middle crosspiece 10, and then to the first winding drum 30 when the winding shaft 21 rotates clockwise (clockwise). winding direction). Similarly, the second balancer spring 33 passes the unwound wire 33a across a folding roller 34b provided on the middle right crosspiece 9, and then transfers the wire 33a to the second winding drum 31 on the right side of the winding shaft 21. It is wound in the winding direction by rotation.
The first balancer spring 32 and the second balancer spring 33, which are the balancers described above, both constantly apply an output to the take-up shaft 21, so that the weight of the entire bed including the bed frame C is divided into two and balanced. There is. For details, see the wire 32a,
In order to act in the direction of unwinding the wires 33a from the winding drums 30, 31 and to obtain a constant output, the winding paths of the wires 32a, 33a forming a chevron shape, that is, the radius length of the output point, and the inside of the chevron portion are set. The wires 32a and 33a are suspended so as to act in a direction to rotate the winding shaft 21 counterclockwise in relation to the internal stress of the mainspring that is sown in conjunction with the drawing operation of the provided wires 32a and 33a. Therefore, due to the action of the first balancer spring 32 and the second balancer spring 33, the wire drums 23, 24,
25, 26 are the respective wires 27a, 27b, 27
c and 27d are rotated in the winding direction to tension the wires 27a, 27b, 27c, and 27d, thereby balancing the bed frame C horizontally.

Next, the lock mechanism F will be explained based on FIGS. 2 and 6. The lock mechanism F has a lock lever 35 connected to a lock shaft 36 projected at a position off the middle of the long side plate 8, which is the front side in FIG. lockshaft 3
6, the front middle crosspiece 11 and the rear middle crosspiece 12 between both long side plates 8, 8' are passed through, and connecting plates 37, 37' are fixed to the front end side and the rear end side of the lockshaft 36, and the lockshaft 36 is horizontally mounted. There is. Both connecting plates 37, 37' have left and right latch bars 38a, 38b, 38c, 38 extending perpendicularly to the lock shaft 36, respectively.
d so as to protrude from latch guides 39 attached to both short side plates 7, 7'. Furthermore, one end of one of the left and right latch bars 38b and 38d is hooked to the connecting portion between the base end of the latch bar and the connecting plates 37', 37, and the other end is hooked to the long side plate 8,
A spring 40 hooked to 8' is tensioned.
By tensioning the spring 40, as shown in FIG. 6, the vertical abutment pin 41a protrudes, causing the connecting plates 37', 37 to be in a vertical state, and the latch bar 38c,
While maintaining the protruding length of the latch bars 38d, 38a, and 38b constant, the rotation range of the connecting plates 37' and 37 is limited by the protrusion of the rotating pin 41b, and the latch bars 38c, 38d, 38a, and 38b are retracted. The length is kept constant.

The above latch bars 38a, 38b, 38c, 38
Since the protruding position of d is on the inside near the guide rail B that is parallel to the same indoor wall D,
Inside these guide rails B, there is a bed frame C.
The latch bars 38a, 38b,
A latch hook 42 that hangs over 38c and 38d is attached. As shown in Fig. 6, the latch hooks 42 are installed at the same position on four opposing guide rails on one side and the other side by raising the bed frame C and placing it at a position corresponding to the upper limit of the guide rail B. , the L-shaped latch 42 is attached in a V-shape so that the tip of the inclined portion 43 faces 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 ,
The latch bars 38c and 38d protrude again to support the bed frame C while suppressing its downward movement. Although not shown, lower the bed frame C and place the guide rail B at a position corresponding to the lower limit of the guide rail B.
Contrary to the above, by attaching the latches 42 at the same four locations in an inverted figure-eight shape so that the tip of the inclined part 43 faces downward, it can be used as a lock when the bed frame C is lowered to the lower limit and fixed. There is. In this case as well, just by lowering the bed frame C, each latch bar is latched and locked. The lock mechanism F can be released by rotating the lock lever 35.
Since the latch bars 38a, 38b, 38c, and 38d are interlocked 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 floor plate 44 covering mechanical parts such as the take-up shaft 21 on its upper surface, on which bedding, etc. can be laid, and a floor plate 44 on its lower surface. A bottom plate 45 is attached. This bottom plate 4
If 5 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 8', 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, 7', for raising and lowering the bed frame C. It is used as a handle.

The operating principle of the elevating bed according to the above embodiment will be explained based on FIG. 7.

The bed frame C is loaded with a weight W including not only its own weight but also the weight of the mechanical parts and the bedclothes.
Then, the weight W is divided into four wires 27a, 27
B, 27c, and 27d in order to divide the bed into four equal parts and suspend it, by constantly acting on the take-up shaft 21 in the direction of raising the bed frame C, that is, in the counterclockwise rotation direction, to balance the weight W. The first balancer spring 32 set to be wires 27a, 27b, 27c, 27d
is tensioned to hold the bed frame C horizontally.

When the bed frame C in the above state is raised, the take-up shaft 21 rotates to the left (counterclockwise) due to the action of the balancer springs 32, 33, so each wire drum 23, 24, 25, 26 rotates in the same direction. and each wire 27a, 27b, 27c, 2
7d is wound up in the same amount, and the bed frame C rises with a light force while maintaining a horizontal balance. Also, when the bed frame C is lowered, the balancer spring 3 outputting to the winding shaft 21 is reversed to the above.
2 and 33, the wire drums 23, 24, 25, and 26 are rotated in the same direction by right rotation (clockwise direction), and the wires 27a and 26 wound around these are rotated in the same direction.
27b, 27c, and 27d are unwound by the same amount, and the bed frame C is lowered with a light force while maintaining a horizontal balance.

Also, when the bed is in use, when the bed frame C reaches the lower limit position, the box part 15 of the suspension support part E of the bed frame C is latched to the stopper 5 set at an arbitrary height of the guide rail B, and the bed frame C is supported. As a result, it can be used as a bed immediately. Furthermore, when the bed is not in use, the latch bar 3 of the locking mechanism F is locked at the upper limit position of the bed frame C.
8a, 38b, 38c, 38d are guide rails C
The bed frame C is supported by the latches 42 and can be stored on the ceiling side.

In this example, the guide rails were attached to the opposite 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 installed vertically from the ceiling to the floor. Of course, it is sufficient to install it in the way it is installed.

[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 head frame can be raised and stored on the ceiling, making the bed less 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 take-up shaft is pivotally supported in the center of the bed frame, an equal load is applied to all the suspended members, and there is no unreasonable load on the suspended members.
Furthermore, a balancer is installed inside the bed frame that provides constant output to the take-up shaft, which not only maintains the balance of the bed frame, but also allows the bed frame to rise smoothly from any height with a small amount of force. can. In addition, since the balancer is provided within the bed frame, it takes up less space than a structure with a pulley on the ceiling and a balance weight, and the installation and assembly are greatly simplified.
