Description

[Detailed description 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 in the ceiling.

[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. 9, in the above-mentioned conventional fixed bed, a bed floor 54 is provided horizontally protruding not from a floor 51 but from a side wall 53 near a ceiling 52 with a slightly raised ceiling. A bed mat or futon was laid on the bed 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 is rotated 90 degrees toward the wall using one side of the bed as a fulcrum, and the bottom of the bed is stored as part of the wall surface.When the bed is in use, contrary to the above, the bed is rotated 90 degrees toward the wall.
It is used by turning it 90 degrees and 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 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 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, two separate guide rails were vertically installed on the same side of the opposite side plates of the bed frame, and these guide rails were fitted to both ends of the shaft at positions corresponding to the side plates of the bed frame. A suspension support portion including a rotating support body is provided protrudingly, and the shaft is inserted into a notch for movement of the shaft formed inside adjacent guide rails on the same side to guide the suspension support portion. The suspension member is fitted with a rail and has interlocking means for synchronously rotating the shafts on both sides, one end side of the suspension member for suspending the bed frame is fixed to the upper part of each guide rail, and the other end side is fixed to the upper part of each guide rail. The suspension member extending from one side is connected to the balancer for one side fixed to the inside of the bed mount via the rotation support, and the suspension member extending from the other side to the balancer for the other side. are connected to each other, and the elevating bed is characterized in that the balance of the bed frame is maintained by the outputs of these balancers.

[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 a suspension connected to a balancer for one side and a balancer for the other side via a rotating support. The bed is suspended by a hanging member, and the constant output of the above-mentioned balancer is applied to the hanging member to balance the weight of the entire bed.
Maintains the balance of the bed frame. When the bed frame is moved up and down along the guide rail, the suspended material is wound up or unwound by the constant output of the balancer, and the rotating support rotates accordingly. The shaft also rotates, and the shafts on one side and the other side rotate in synchronization due to the interlocking means provided on this shaft, and the guide rail moves up and down along the movement notch of the shaft, so that the suspension support is The bed frame is raised and lowered while being balanced horizontally while being guided by the guide rail.

As shown in Fig. 1, two guide rails B are installed in parallel on one side of the indoor wall D over a range that does not reach the floor from the indoor ceiling, and on the other side of the opposite indoor wall D. Two wires are attached in parallel. If you do not place a desk or luggage on the floor area surrounded by guide rail B, use guide rail B.
The lower end may be placed close to the floor surface. As shown in FIGS. 3 and 5, in the lower part of the guide rail B, a plurality of daruma holes 4 are formed in the bottom 1' of the section steel, and the back surface 5' of the stopper 5 is L-shaped in side view. A protrusion 6 is formed to fit into the daruma hole 4 and to be engaged, thereby making the stopper 5 removable. This stopper 5 is used to adjust and position the lower limit height of a bed frame C, which will be described later, and is adjusted to a position where each guide rail 7B has the same height. Also the first
As shown in the drawings and FIG. 3, inside the adjacent guide rails B on one side and the other side, there is a moving notch 1 through which a shaft 13 (to be described later) is inserted and the shaft 13 can be moved. ″ to guide rail B
It is formed in the longitudinal direction.

As shown in FIG. 2, the bed pedestal C is composed of short side plates 7, 7' and long side plates 8, 8' to form a rectangular shape in plan view. These side plates 7, 7',
On the inside surrounded by 8 and 8', a center middle crosspiece 9, a right middle crosspiece 10, and a left middle crosspiece 11 are arranged to reinforce the bed frame C.

At the outer ends of both short side plates 7, 7', a rotary support 1 is provided at a position corresponding to the guide rail B.
2, two suspension support parts E are provided protrudingly provided on each side. The rotation supports 12 on one side and the other side are pivotally fitted to both ends of the shaft 13 on the same side, and are pivotally attached to rotate integrally with the shaft 13. As shown in FIGS. 3 and 4, this suspension support part E pivotally supports the upper steady-stop roller 14 and the lower steady-stop roller 14', respectively, and has a box part 15 in contact with the stopper 5 at the bottom. is forming. An opening 16 for attaching the rotating support 12 is formed between the box portion 15 and the upper steadying roller 14. On both sides of this opening 16, bent mounting parts 17 are provided to protrude, and are fitted onto component mounting brackets 18 protruding from the bed frame C side, and the entire suspension support part E is fixed in a protruding shape by welding. ing. A cutout for inserting the shaft 13 is formed on one side of the bent mounting portion 17, and after the shaft 13 is inserted into the cutout, it is fitted onto the member mounting bracket 18. In the opening 16,
Mounting flanges 19 are formed on the top and bottom of the sprocket 2.
A rotary support body 12 that supports the rotary support 12 is attached to the mounting collar 19 by fitting the sprocket 20 therein and tightening bolts to the mounting collar 19. As shown in FIG. 4, the suspension support portion E is fitted into each of the guide rails B, more specifically, into the section steel 1.

The shaft 13 is provided with interlocking means F for rotating the shafts on one side and the other side in synchronism. As shown in FIG. 1, the interlocking means F is
A pulley 21 is fitted in an intermediate position between both shafts 13 so as to be rotatable integrally with the shaft 13, and a rope 22 (or belt) is crossed between both pulleys 21. Thereby, both shafts 13 are transmitted to rotate synchronously. Instead of the interlocking means F, as shown in FIG. 8, transmission may be performed by gears. In this case, instead of the pulley 21, a bevel gear 23 is installed at an intermediate position of the shaft 13.
A transmission shaft 25, in which a bevel gear 24 meshing with the bevel gear 23 is shaft-fitted on both ends thereof, is positioned between both shafts 13, and transmits transmission so that both shafts 13 rotate synchronously.

Next, one side balancer spring 2, which is a balancer, is installed at both ends of the central crosspiece 9 of the bed frame C.
6, 27 and balancer spring 28 for the other side,
29 are permanently installed. A suspension member G, in which a wire 30 and a chain 31 are connected, is connected to the balancer springs 26, 27, 28, and 29. As shown in FIG. 3, the tip of the chain 31, which is one end of the suspension member G, is attached to a hook part 32 hooked to a bolt or nut on the bottom part 1' of the section steel 1 at the upper part of the guide rail B. , the link part of the chain 31 is hooked. On the other hand, in the middle of the suspension member G, the chain 31 hangs down inside the section steel 1 of the guide rail B, meshes with the sprocket 20 of the rotation support body 12 of the suspension support part E, and connects the wire 30 at the tip of the chain 31 to the sprocket 20 of the rotation support body 12 of the suspension support part E. The respective balancer springs 26, 27, 28,
It is connected to 29. The suspension member G may be entirely made of wire, and instead of a sprocket, pulleys may be fitted to both ends of the shaft, and the wire may be passed therethrough.

The balancer springs 26, 27, 28,
29 always gives an output to the suspension member G, and balances the weight of the entire bed including the bed frame C by dividing it into four equal parts (in this example, balancer springs are fixed at four locations). That's what I do.
For details, see balancer springs 26, 27, 2.
8, 29 act in the direction of winding up the hanging material G, and in order to obtain a constant output, a wire 30 having a chevron shape is installed in the winding path, that is, the output point radius length and the wire provided inside the chevron portion. In relation to the internal stress of the mainspring that is applied in conjunction with the drawer operation of 30, the hanging material G is always output in the winding direction. Therefore, balancer spring 2 for one side
6, 27 and other side and balancer spring 2
8 and 29, the suspension members G are equally tensioned at four locations, and the bed frame C is balanced horizontally.
In addition, balancer springs 26, 27, 28, 2
One 9 may be installed for one side and one for the other side. In this case, the two suspension members extending from one side are connected to one balancer spring for one side, and the other side is similarly connected to one balancer spring for the other side. Divide the bed weight into two equal parts to ensure balance.

Next, the lock mechanism H will be explained based on FIGS. 2 and 6. In the lock mechanism H, a lock lever 34 connected to a lock shaft 33 protrudes from a long side plate 8 on the near side in FIG. The lockshaft 33 has connecting plates 35, 35' fixed to its front end and rear end, and is horizontally suspended parallel to the center middle crosspiece 9 and the right middle crosspiece 10 at an intermediate position. Double connection plate 3
5 and 35', left and right latch bars 36a and 36 extending perpendicularly to the lock shaft 33, respectively.
b, 36c, 36d are extended, both short side plates 7,
It projects from a latch guide 37 attached to 7'. Furthermore, one side of the latch bars 36b and 38d is provided with a base end of the latch bar and a connecting plate 3.
A spring 38 is tensioned, one end of which is hooked to the connecting portion with 5, 35', and the other end of which is hooked to the long side plates 8, 8'. Due to the tension of the spring 38, as shown in FIG. 6, the vertical abutting pin 39a protrudes to bring the connecting plates 35, 35' into a vertical state, keeping the protruding lengths of the latch bars 36a, 36b, 36c, and 36d constant, and also The protrusion of the pin 39b limits the rotation range of the connecting plates 35, 35', and the latch bars 36a, 36b, 36c, 36
The retraction length of d is maintained constant.

The latch bars 36a, 36b, 36c, 36
The protruding position of d is on the outside close to the guide rails B that are parallel on the same indoor wall D as shown in Fig. Latch hooks 40 are attached to the latch bars 36a, 36b, 36c, and 36d. As shown in FIG. 6, the latch hooks 40 are installed at four identical positions on the guide rails facing each other on one side and the other side, by lifting the bed frame C and placing it at a position corresponding to the upper limit of the guide rail B. The L-shaped latch 40 is attached in a V-shape so that the tip of the inclined part 41 faces upward. Then, the protruding tips of the latch bars 36a and 36b move upward from below the latch hook 40, retract by the stroke of the undulation that makes sliding contact with the slope part 41, and when they cross the slope part 41, the action of the spring 38 The latch bars 36a and 36b protrude again, suppressing the downward movement of the bed frame C. Also, although not shown, lower the bed frame C to a position corresponding to the lower limit of the guide rail B, and latch 40 at the same four positions on the guide rail B.
Contrary to the above, by attaching the inclined portion 41 in an inverted V shape so that the tip of the inclined portion 41 faces downward, it is used as a lock when lowering and fixing the bed frame C to the lower limit. In this case as well, just by lowering the bed frame C, each latch bar 36a, 36b,
36c and 36d are engaged with the latch 40 and locked. The lock mechanism H can be released by rotating the lock lever 34.
Since the latch bars 36a, 36b, 36c, and 36d 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 balancer springs 26 and 2 on its upper surface.
A floor plate 42 covering the mechanisms 7, 28, 29, etc. is stretched on which a futon or the like can be laid, and a bottom plate 43 is stretched on the lower surface. If this bottom plate 43 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 44 is attached to the upper part of the bed frame 8', and a handle 45 is attached near the middle of the bottom plate 43 of the bed frame C in parallel with the short side plates 7 and 7', so that the bed frame C can be raised and lowered. 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.

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 above weight W into four equal parts and hang it on the four suspension members G, G ₁ , G ₂ , G ₃ , G ₄ , each suspension member G ₁ is equipped with a balancer spring for one side. 26, the suspension member G ₂ is connected to the balancer spring 27 for one side, the suspension member G ₃ is connected to the balancer spring 28 for the other side, and the suspension member G ₄ is connected to the balancer spring 29 for the other side. There is. The above balancer springs 26, 27, 2
8 and 29 always give a constant output that is in balance with the weight W, tensioning the hanging member G and holding the bed frame C horizontally.

When the bed frame C in the above state is raised, both of the shafts 13 on which the sprocket 20 is fitted are moved in conjunction with the upward movement of the balancer springs 26, 27 for one side and the balancer springs 28, 29 for the other side. Since they are rotated synchronously by the means F, the hanging members G ₁ , G ₂ , G ₃ , and G ₄ are evenly wound up, and the bed frame C is raised with a light force while maintaining a horizontal balance. Also, when the bed frame C is lowered,
Contrary to the above, the balancer springs 26, 2
7, 28, and 29 unwind the hanging materials G ₁ , G ₂ , G ₃ , and G ₄ evenly, so the interlocking means F is activated and the bed frame C is lowered with a light force while maintaining the horizontal balance. do.

In this example, guide rails were attached to the opposing surfaces of the indoor walls, but this is possible 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 only necessary to install it as 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 bed 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 balancer is fixed and the shafts on both sides are rotated synchronously by interlocking means, the bed frame can be raised and lowered with a small amount of force while maintaining balance with the bed frame.
The bed frame moves up and down horizontally, so the futon does not shift to one side.
