Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a retractable sofa/bed device that can be stored in a storage box when not in use.

[Technical background of the invention and its problems]

Beds installed indoors occupy a large amount of indoor space, so they have the disadvantage of being very intrusive when not in use. Therefore, a so-called sofa bed is known in which the bed can be used as a sofa when it is not used as a bed. However, even the sofa bed has the disadvantage that it occupies a large amount of indoor space and is a nuisance when it is not used as either a bed or a sofa.

In order to eliminate these drawbacks,
A retractable soft bed shown in FIGS. 7 and 8 of Japanese Patent No. 43726 has been proposed. In this retractable soft bed, a guide groove is formed along the height direction in the storage column, and a front wheel provided on one of the two divided beds is engaged with this guide groove. At the same time, a cable having one end connected to the one bed is wound up by a winding machine. Depending on the winding length of the rope, one bed can be held at any angle with respect to the other bed which is in a horizontal state and protrudes from the storage body, so that it can be used as a sofa.

However, according to such a structure, one bed in an inclined state is suspended by a cable, so although the other bed is prevented from moving forward, there is no restriction on running backward. It has not been. Therefore, when a user sits on the other bed and moves the back of the bed backwards, the other bed moves in the direction of entering the storage body, and the inclination angle of one bed also changes in conjunction with this movement. The drawback was that it could not be used in a stable manner as a sofa because of the heat.

[Purpose of invention]

This idea is a retractable sofa that can be converted into a sofa and bed, and can be stored in a storage box when not in use, and can be used in a stable state without shifting when used as a sofa. The object of the present invention is to provide a dual-purpose bed device.

[Summary of the idea]

This idea provides rails and guide bodies along the vertical direction on both inner surfaces of a storage box with an open front.
A roll provided on the lower surface of one end of the first cushion body is engaged with the rail, and one end of the second cushion body, which has legs protruding from the four corners of the lower surface, is rotated on the other end of the first cushion body. The pair of cushion bodies are movably connected, and one end of the cable body is connected to one end of the first cushion body, and the other end of the cable body is connected to a drive source to drive the pair of cushion bodies. When the cushion is stored in a storage box or converted into a sofa or bed, the leg provided on the lower surface of the other end of the first cushion body comes into contact with the guide body and the first cushion This is a retractable sofa/bed device that prevents the body holding angle from changing.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings. 1 in FIG. 1 is a storage box with an open front. Inside the storage box 1, an inner top plate 3 is provided parallel to and spaced apart from the top plate 2, and a pair of inner plates 5 are provided parallel to and spaced apart from both side plates 4. As shown in FIG. 3, a substantially U-shaped guide groove 7 is formed in the lower surface of the inner top plate 3 and the upper surface of the bottom plate 6, and is open on one side plate 4 side. A bendable plate-shaped shutter 8 is provided in these guide grooves 7 so as to be slidable by engaging the upper and lower ends thereof. This shutter 8 is set to a length such that when one end is slid to the end of the guide groove 7 located on the back plate 9 side of the storage box 1, the other end does not protrude into the front opening of the storage box 1. Further, a pair of locking plates 11 having through holes 10 are provided protruding from the outer surface of one end of the shutter 8, as shown in FIG. A spring 13 is provided between the locking plates 11 and has stoppers 12 fixed to both ends thereof which are larger than the through hole 10. Both ends of the wire 14 passed through the through hole 10 are fixed to the stopper 12, respectively. This wire 14 is connected to a driven pulley 15 rotatably provided on one side in the width direction of the rear side of the storage box 1, and a driving pulley 15 fitted on the rotating shaft 17 of a first motor 16 on the other end. It is stretched between the pulley 18 and the pulley 18. Therefore, when the first motor 16 is activated and the wire 14 is driven to travel in the direction indicated by arrow a in FIG. It is becoming more and more common. The travel range of the shutter 8 is controlled by a limit switch (not shown).

Side plates 4 and inner plates 5 on both sides of the storage box 1 in the width direction
A pair of mounting members 21 whose upper and lower ends are fixed to the top plate 2 and the bottom plate 6 are respectively provided in the portion between them, and a rail 22 having a substantially U-shaped cross section is attached to each pair of mounting members 21. It is being This rail 2
2 is along the vertical direction of the side plate 4, and has an arc shape with a lower end protruding toward the front side of the storage box 1 than the upper end. As shown in FIG. 5, the pair of inner plates 5 are provided with a through hole 23 having a shape corresponding to that of the rail 22, and a hole 23 is formed on the inner surface of the half of the height direction at a position on the rear side of the rail. An arc-shaped guide body 24 whose lower end projects further toward the front side of the storage box 1 than its upper end is attached.
Both ends of the shaft body 25 are inserted into the pair of through holes 23 . A first pulley 26 and rotatable rollers 27 are attached to both ends of the shaft body 25, and these rollers 27 are slidably engaged with the rail 22. Both ends of the shaft body 25 located on the inner surface side of the inner plate 5 are attached to connectors 29 provided on the lower surface of one end of the first cushion body 28 . One end side of a second cushion body 30 is pivotally attached to the other end side of the first cushion body 28 by a hinge or the like (not shown). Legs 32 and 33, each having a caster 31 attached to its lower end, are provided on both sides of the lower surface of the other end of the first cushion body 28 and at the four corners of the lower surface of the second cushion body 30, respectively. The caster 31 of the leg 32 of the first cushion body 28 rolls along the guide body 24 when the first cushion body 28 is held in an inclined state in the storage box 1, as will be described later. I'm starting to do that. Further, when the second cushion body 30 moves in and out of the storage box 1 as described later, the casters 31 of the legs 33 are connected to the pair of running grooves 34 formed in the bottom plate 6 of the storage box 1 and the ends of the running grooves 34. The vehicle runs on the upper surface of an inclined body 35 that is sloped low toward the front side of the storage box 1 provided therein.

One loop-shaped end of a wire 36 serving as a cord is engaged with first pulleys 26 provided at both ends of the shaft body 25 . The other ends of these wires 36 are connected to a second motor 3 as a drive source provided at the center of the upper surface of the inner top plate 3 in the width direction.
They are respectively wound in opposite directions around a drum 39 fitted onto a rotating shaft 38 of No. 7. The running direction of the pair of wires 36 is changed by a plurality of second pulleys 40 rotatably provided at both ends of the inner top plate 3.

According to this structure, when the second motor 37 is operated in the direction of winding the pair of wires 36 around the drum 39, the first cushion body 38 is drawn into the storage box 1 by these wires 36. Since the second cushion body 30 is interlocked with this, the first and second cushion bodies 28 and 30 are stored in the storage box 1 in a state where they are joined in a substantially straight line as shown by the chain line in FIG. be done. At this time, the caster 31 of the leg 32 of the first cushion body 28 is located at the upper end of the guide body 24, and the second cushion body 30
The casters 31 of the legs 33 are located on the upper surface of the inclined body 35, and the first and second casters are arranged in a straight line.
The cushion bodies 28, 30 are in a slightly inclined state with their lower ends protruding more forward than their upper ends. In this manner, with the first and second cushion bodies 28 and 30 housed in the storage box 1, the first motor 16 is operated to run the shutter 8, and the shutter 8 moves the storage box 1. By closing the front opening of the storage box 1, not only the appearance is good, but also the first and second cushion bodies 28, 30 will not inadvertently protrude from the storage box 1.

When using the first and second cushion bodies 28 and 30 as a sofa, the shutter 8 is moved in the opposite direction to open the front surface of the storage box 1, and then the second motor 37 is activated. Then, the other end of the wire 36, one end of which is connected to the first cushion body 28, is sent out from the drum 37. Then, the first and second cushion bodies 28,
30 is released from the suspended state, the caster 31 of the leg 33 of the second cushion body 30 runs from the inclined body 35 in the running groove 34 due to the weight of these cushion bodies 28, 30, and the first The caster 31 of the leg 32 of the cushion body 28 is connected to the guide body 2.
Roll along 4. Then, when the second cushion body 30 protrudes from the storage box 1 and becomes horizontal, and the first cushion body 28 is tilted as shown in FIG. 2, the second motor 37 is stopped. The second cushion body 30 serves as the seat, and the first cushion body 28 serves as the back, allowing these cushion bodies 28 and 30 to be used as a sofa. In this state, the first cushion body 2
8, rollers 27 at both ends of a shaft 25 provided at one end engage with the rail 22, and casters 31 of legs 32 provided at the other end abut against the guide body 24. Therefore, even if the user sits on the second cushion body 30 and moves the butt part backward, the guide body 24 prevents the user from moving backward, so that the first cushion body 28 will not fall forward. Further, since the first and second cushion bodies 28 and 30 are suspended by the wire 36, the second cushion body 3
0 is prevented from moving forward. Therefore, since the second cushion body 30 does not shift in the front-back direction and the inclination angle of the first cushion body 28 does not change, it can be used as a sofa in a stable state.

From this state of the sofa, the second motor 37
The wire 36 is further fed out by activating the
If the cushion body 28 is laid down so as to be parallel to the second cushion body 30, the plane formed by the upper surfaces of the pair of cushion bodies 28 and 30 can be used as a bed surface. At this time, since the roller 27 of the shaft body 25 provided on the first cushion body 28 is engaged with the rail 22, the first and second cushion bodies 28 and 30 do not shift in the front-back direction. Furthermore, since the first cushion body 28 is held in a horizontal state by the wire 36, it can be used as a bed in a stable state.

[Effect of idea]

As described above, this invention provides a first cushion body and a second cushion body which are rotatably connected and can be taken in and out of a storage box, and these cushion bodies are made to protrude from the storage box and are placed horizontally. By placing them side by side, it can be used as a bed, and by holding the second cushion body horizontally and the first cushion body tilted, it can be used as a sofa, and when converted into a sofa, the lower end side of the first cushion body can be used. The legs provided on the storage box are brought into contact with guide bodies provided on the inner surface of the storage box. Therefore, the contact between the guide body and the legs prevents the first cushion body from falling forward in conjunction with the movement of the cushion body in Item 2, so the sofa remains stable and good. It can be used for.
