Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electric elevating bed that can be stored in the ceiling when not in use.

[Problems to be solved by the prior art and the invention today]
With the diversification of lifestyles, more and more rooms are equipped with beds. However, if this bed is of a fixed type, the floor space it occupies cannot be used effectively, and in some rooms where the area of the room is small, it is virtually impossible to install a bed. Therefore, conventionally there are beds that can be made to stand up and be stored on the wall.

This product has a problem in that the mat or futon must be tied up to prevent it from falling off when stored.

[Means for Solving the Problems] The present invention was devised in view of the above-mentioned circumstances with the aim of providing an electrically-operated elevating bed that can eliminate these drawbacks.

A plurality of supports protruding from the bed frame are fitted to vertically facing guide rails installed between the ceiling and the floor so as to be movable up and down, and the guide rails and the bed frame are connected via each support. A wire is stretched between the wires, and the wire is connected to a winding mechanism equipped with an electric motor, and the wire is connected to a winding mechanism equipped with an electric motor. The present invention is characterized in that the bed frame is automatically displaceable between a storage position on the ceiling side and a lowered position where sleeping is possible while maintaining a horizontal position by winding and unwinding the wire during driving.

With this configuration, the present invention enables the bed to be stored in a horizontal position on the ceiling when not in use, thereby ensuring a wide effective area of the room and preventing the futon from slipping down. This is what I did.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a bed frame for an elevating bed, and the bed frame 1 is formed into a rectangular shape with a side plate 1a, an inner plate 1b, etc., and an operating shaft 2 is rotatably mounted on the upper surface of the approximately central part of the bed frame 1. It is freely supported. A driven sprocket 3 and four sets of wire drums 4 having the same diameter are integrally supported on this operating shaft 2. A power transmission chino 7 is suspended between the wire drum 4 and the operating shaft 2, which rotates together with the wire drum 4 in conjunction with the forward and reverse rotation of the electric motor 5. wire 1
7 can be evenly wound up and unwound, and in this way a winding mechanism is formed on the bed frame.

A cylindrical guide 8 is integrally provided at each of the four joints of the bed pedestal 1, and a cylindrical support is attached to the guide 8 so as to be movable in the longitudinal direction of the bed pedestal 1. A body 9 is fitted so as to be freely retractable. and support 9
is fixed and held by a screw 9b in a state where it is positioned at a desired position. Here, the support body 9 is set so that it can not only move forward and backward, but also adjust its rotation in the lateral direction using the screw 9b as a fulcrum.

A support roller 10 is rotatably mounted inside the support 9 with a portion thereof peeking out from the tip of the support 9, and a guide roller 11 is rotatably supported on the lower surface of the support 9. . On the other hand, 12 is a guide rail installed between the ceiling and the floor and facing in the vertical direction, and the guide rail 12
The tip of the support body 9 is fitted into the support body 9 so as to be vertically movable.

That is, the guide rail 12 of the embodiment has a fixed side 13a fixed to the body by bolts 12a etc., a side piece 13b rising from one side edge of the fixed side 13a, and a side piece 13b rising from the rising tip edge of the side side 13b. A pair of bent object plates 13 formed to have a front piece 13c that is bent in the opposite direction to the fixed side 13a and a guide piece 13d that is bent from the first front piece 13c toward the side side 13b again is guided. It is formed by integrally fixing and interposing both leg pieces of a substantially U-shaped intermediate member 14 between side edges 13b by welding or the like, with the pieces 13d facing each other with a predetermined interval.

The guide rail 12 has an opposing guide piece 13d.
Adjust the expansion and contraction of the support body 9 so that the guide roller 11 is positioned between them (at this time, if necessary, adjust the horizontal rotation), and fit the tip of the support body 9 so that it can move up and down. It is only necessary to adjust the support roller 10 as much as possible.
The portion protruding from the support body 9 faces the inner side of the guide rail 12 near the bottom piece of the intermediate member 14. On the other hand, an intermediate material 14 is provided at the upper end of the guide rail 12.
A substantially mouth-shaped auxiliary plate 15 is integrally fixed to the auxiliary plate 15, and one end of the wire 17 is attached to a locking tool 16 screwed between the front piece of the auxiliary plate 15 and the bottom piece of the intermediate member 14. As a result, one end of the wire 17 is supported at both ends.

Furthermore, a cover plate 12a is attached to the upper end of the guide rail 12 so that its vertical position can be adjusted freely, and it covers the gap between the upper end of the guide rail 12, which has been adjusted to be slightly shorter, and the ceiling i. ing. The wire 17 is suspended from the support roller 10 through the guide rail 12, and stretched so as to extend through the support body 9 and into the bed frame 1, and the other end is wound around each corresponding wire drum 4. is connected to the winding mechanism. Then, as described above, the wire 17 is wound as the electric motor 5 is driven;
Due to the rewinding operation, the bed frame 1 moves to the guide rail 12.
The bed frame 1 can be moved up and down in parallel along the horizontal position, thereby automatically raising and lowering the bed frame 1.
An automatic lifting mechanism is configured. Furthermore, guide rail 1
At the lower end of the guide piece 13d, a plurality of locking holes 13a are formed at predetermined intervals. and bed stand 1
is lowered as described later until the abutment piece 11a of the guide roller 11 is abutted and supported by the stopper 18 which is engaged and fixed in the locking hole 13e.

This allows support and holding by the stopper 18 instead of the wire.

With this configuration, there is a slack detection mechanism 1 in the wire tensioning route.
9 is provided. That is, although the slack detection mechanism 19 is provided on the bed frame 1 side in the embodiment, a movable body 21 rotatably supporting a pulley 21a is movably provided on a base 20 that constitutes the slack detection mechanism. has been
A wire 17 is suspended around this pulley 21a, and this movable body 21 is moved by a bullet 22.
The inclined surface 21b of the pedestal 20 is constantly biased in the direction in which it comes into contact with the inclined surface 20a of the base 20. And the movable body 21 is
When the wire 17 is under tension due to the weight of the bed frame 1, the tension force overcomes the biasing force of the bullet 22 and the wire 17 is displaced until it comes into contact with the stopper 23. on the other hand,
24 is a detection switch provided on the base 20, and the switch part 24a of the detection switch 24 is connected to the movable body 21.
When the movable body 21 is in contact with the stopper 23, it is in contact with the large diameter part of the first operating rod 21c and is turned ON. If the wire 17 becomes slack due to its downward movement being restricted by the stopper 18 on the guide rail 12 side, or by being restricted from descending by an obstacle between it and the floor,
The movable body 21 moves because the biasing force of the ammunition 22 overcomes the tension of the wire 17, and as a result, the detection switch 24 is switched so that the switchper 24a contacts the narrow diameter portion 21d of the operating rod 21c and switches to the ear. In this way, the lowering drive of the electric motor 5 is set to be automatically stopped.

Next, various safety devices of the electric elevating bed will be explained. First, the first safety device is to ensure that the bed frame 1 does not move inadvertently even if the lift switch 40 is operated while one person is using the bed. The switch can be made by raising and lowering a guard handrail 25 provided at 1. That is, this guard handrail 25 is to protect the person sleeping on the bed from falling from the bed, but the guard handrail 25 has a generally mouth-shaped shape, and the pads 25a provided at the lower ends of both legs are , and is fitted into the case body 25b provided on the side plate 1a of the bed frame 1 so as to be movable up and down while being prevented from coming out. The guard handrail 25 is
By lowering the backing plate 25a into contact with the bottom of the case body 25b while the person is in the upright position, the person on the bed is held in the upright position and serves to prevent the person from falling. 25, and remove the case body 2.
5b is transformed into a storage position by lying down inward to the side of the notch 25c formed at the upper end,
and.

The futon can be pressed down.

On the other hand, an operating rod 26 is provided on the bottom surface of the case body 25b, and is configured to be retractable while being constantly urged upward by the ammunition 26a. When the guard handrail 25 is in the upright position, the operating rod 26 moves downward against the biasing force of the projectile 26a due to the weight of the guard handrail 25, and when in the fallen position, the operating rod 26 moves upward. However, the detection switch 27 provided opposite to this operating rod 26 is
When the aforementioned guard handrail 25 is in the upright position, it becomes a lug when it comes into contact with the large diameter part of the operating rod 26, and when it is in the collapsed position, it becomes ON when it comes into contact with the small diameter part 26b, and thereby, The electric motor 5 is configured to operate only when the guard handrail 25 is in a prostrate position.

On the other hand, the second safety device is to avoid the danger of luggage or people being caught between the bed frame 1 and the ceiling while it is being moved upward, and is as follows.

That is, a detection switch 29 is provided on the ceiling via a frame 28, and a plate-shaped detection body 30 is installed on the frame 28.
Normally, it hangs down to the locking piece 28a provided on the frame 28, but as mentioned above, the object caught between the bed frame 1 and the ceiling is suspended due to the upward movement of the bed frame 1 itself. When the detection body 30 comes into contact with the detection body 30 and is pushed up, the detection switch 29 becomes the key to stop the drive of the electric motor 5, thereby preventing an obstacle from being caught between the ceiling and the bed frame 1. It is configured in such a way that it will not be damaged.

Next, the third safety device is to prevent people from getting caught between the bed frame 1 and the floor while it is moving downward. This is ensured to some extent by the aforementioned slack detection mechanism 19 of the wire 17, but since this has to regulate the descent of the bed frame 1, an obstacle must be removed for this to operate. A certain amount of pressure must be applied, and especially from the center of the bed frame, it will not work unless the entire bed load is supported and the wire 17 is loosened, so something that is easily damaged cannot withstand it. To avoid this, it is absolutely necessary for safety to have something that can detect an obstacle between the floor and the bed frame and immediately stop the descent, and this is what we provide. That is, this device includes a plurality of detection switches 31 provided on the bottom of the bed frame 1, and a locking piece 32a that is normally
When an obstacle comes into contact with the detecting body 32 and pushes up the detecting body 32 as the bed frame 1 descends, the detection switch 31
The electric motor 5 stops when the line becomes a line, and the lowering of the bed frame 1 is restricted, thereby eliminating scratches caused by obstacles.

Furthermore, there is a fourth safety device, which is of a nature that further complements the second safety device described above. That is, the second safety device does not activate the detection unless the bed frame 1 moves upward and pushes up the detection body 30 installed on the ceiling. This is particularly effective when the vehicle is in the air, but if a reasonably sensible person notices an erroneous operation, he or she can make an emergency stop before the vehicle touches the ceiling, and this is why this is provided. That is, in this device, a generally mouth-shaped detection body 33 is fitted onto the upper edge of the four peripheral side plates 1a of the bed frame 1 in a state where it is constantly lifted upward by the biasing force of the first bullet 34, and the detection body 33 in the shape of a bracket is An operating body 35 is installed vertically. Then, the switch part 36a of the detection switch 36 that is in contact with the actuating body 35 is connected to the detection body 33.
When a person presses down, the small-diameter portion 35a contacts the large-diameter portion, forming an ear, thereby stopping the electric motor 5.

The electric circuit of the electric motor 5 is as shown in FIG. 19, and the above-mentioned slack detection mechanism 19. The detection switches 24 and 31 of the third safety device are connected to the descending circuit, and the detection switches 27 and 29 of the first and second safety devices are connected to the ascending circuit.
Detection switches 36 of the fourth safety device are provided in both circuits, respectively, and are adapted to perform corresponding open-p operations. Here, PBU is the upward switch, PBD is the downward switch, LSU is the upper limit switch, and L
SD is a lower limit switch, and B is a brake.

Furthermore, the electric bed of this embodiment has a sensing body 30 provided on the ceiling. Lighting lights 37 and 38 are installed inside the bed so as to be covered by the detection bodies 32 provided on the bottom surface of the bed frame 1, and by turning on the ceiling lighting lights 37 when the bed is in use, it is possible to illuminate from above the bed. By opening the pedestal side illumination light 38 when the bed is stored, illumination can be provided from the bed pedestal 1 instead of the ceiling. In addition, a ladder 39 is provided on the bed pedestal 1 so that it can be stored in a variety of ways.
If you pull out 9, you can easily get on and off the bed. Further, 40 is a lift switch (the PB
υ, corresponds to PBD), and the lift switch 4
The electric motor 5 can be driven in forward and reverse directions by the operation of 0. Further, the electric motor 5 has a limit switch for the upper and lower limits (which corresponds to the LSD and LSU described above, but will not be described in detail) that detects the rotation speed of the motor and detects its upper and lower limits.

For example, the one shown in Japanese Utility Model Publication No. 56-46270) is installed inside.

In an embodiment of the invention constructed as described.

When the bed frame 1 is operated by pressing the lift switch 40 to drive the electric motor 5 in the forward and reverse directions, the four wires 17
is evenly wound around the wire drum 4 or rewound, and as a result, the bed frame 1 moves up and down while maintaining a substantially horizontal state. When sleeping on this bed, the lowering lift switch 40 is opened to drive the electric motor 5, and the bed frame 1 is lowered while maintaining the horizontal position as described above. When the contact piece 11a of the guide roller 11 contacts the stopper 18 to restrict the descent of the bed frame 1 and loosen the wire 17, this is detected by the wire 17 slack detection device 19, and as a result, the electric Motor 5 stops.

The bed frame 1 is supported and held by a stopper 18. After that, the guard handrail 25, which is a hindrance to sleeping, can be moved to the standing position. On the other hand, bed frame 1
When you want to store the guard rail 25, open the lift switch 40 for raising and lower the electric motor 5.
, and wind the wire 17. In this way, the bed frame 1 is automatically raised to the ceiling side and stored while maintaining its horizontal position.

In this way, according to the present invention, the bed frame 1 can be stored on the ceiling side while maintaining its horizontal position.

When the bed is not in use, the bed does not get in the way,
A large effective indoor space can be secured, and a comfortable living environment can be enjoyed. Moreover, the stored bed frame 1 is not made to stand up as in the past, but is stored upward in a horizontal position, so there is no chance of the futon slipping down, and this bed frame 1 The vertical movement of f! Since this is done automatically by winding and unwinding the wire 17 as the electric motor is driven, one person only needs to perform a one-touch operation of turning on the lift switch 40. Since the wires 17 are wound simultaneously and evenly, there is no problem such as tilting of the bed frame 1, and a horizontal posture can always be maintained.

Moreover, the lowering of the bed frame 1 is determined by the guide roller 11 coming into contact with the stopper 18 and the wire 17 loosening. Since the bed frame 1 is fixedly held by the guide rail 12 via the guide rail 18, it can be held securely without any sense of instability.
There is no need for it, and it does not sway. Further, this lowering position can be arbitrarily selected by changing the position of the stopper 18. Therefore, even if furniture such as a desk is placed below the bed frame 1, or luggage is placed under the bed frame 1, it will not come into contact with the furniture. This is convenient because the bed frame 1 can be stopped at +1ij.

In this manner, the present invention allows the bed frame 1 to be horizontally raised and lowered by electric power, and its excellent safety is further ensured by various safety devices. That is,
By making the lifting and lowering movement of the bed frame 1 electric, it was possible for one person to accidentally turn on the lifting switch 40 when one person was on the bed.
, there is a risk that the bed frame 1 will rise, but in this case, when a person sleeps on the bed, the guard rail 2
5 is kept in an upright position so as not to get in the way. When the guard handrail 25 is held in the upright position in this way, the detection switch 27 constituting the first safety device is in the snoring position as described above, and therefore, if the lift switch 40
Even if the switch is turned on, the electric motor 5 will not be driven, making it highly safe.
It is also used for raising and lowering the guard rail 25, therefore, the switch operation is not necessary and the hassle is eliminated, but when going to bed, the guard handrail 25 must be raised. There is no danger that the bed frame 1 will rise while sleeping, and in addition to simplifying the structure of such a safety device, it is possible to reduce the number of parts. Furthermore, the @ moving motor 5 does not operate unless the lift switch 40 is turned ON and L while the guard handrail 25 is in the reclined position, so the guard handrail 25 does not get in the way when the bed is stowed. There is an advantage that the pedestal 1 can be stored at a position as high as possible.

Furthermore, the electric motor 5 will not be driven unless the guard handrail 25 is lowered in this way;
Alternatively, if the child is allowed to ascend with the luggage left there, there is a risk that the child may get caught between the ceiling and the ceiling and be injured or the luggage may be damaged, but this can be ensured by the second safety device mentioned above. It will be avoided. In other words, in this case, if there is an obstacle such as a person or luggage on the rising bed frame 1, the bed frame 1 will rise considerably.

These obstacles come into contact with the detection body 30 provided on the ceiling side, push it up, and are detected when the detection switch 29 is turned on, and the electric motor 5 is stopped.

Therefore, the danger of an obstacle being pressed between the ceiling and the bed frame 1 can be reliably avoided. In addition, when the obstacle is a person, before activating the second safety device each time, the fourth safety device, that is, the detection body 33 provided on the four peripheral side plates 1a of the bed frame 1, must be pushed down by hand or the like. As a result, an abnormality is detected and the electric motor 5 is brought to an emergency stop, resulting in excellent safety. Moreover, since this thing is installed on the side plates around the circumference, it can be pushed down anywhere, and it emits great power for making instant decisions. Therefore, if these three types of safety devices are used in combination, double safety can be ensured when raising the bed frame 1.

Further, when descending, the bed frame 1 is restricted from descending by the guide roller 11 coming into contact with the stopper 18 and the wire 1
This is done in conjunction with the slack detection mechanism 19 detecting that each wire 17 has become loose.
Therefore, if an obstacle is near one of the guide rails 12 on the floor, the presence of the obstacle restricts the downward movement of the guide roller 11 on that side. The loosening of the wire 17 also means that the electric motor 5 stops, and this alone ensures considerable safety, but the third safety device mentioned above also prevents the electric motor 5 from stopping if there is an obstacle on the floor. If there is an obstacle in the center, the obstacle is detected by pushing up the detection body 32, which causes the electric motor 5 to automatically stop. Safety will also be ensured.

Furthermore, since the lift switch 40 (P[]U, POD) operates only when it is pressed, if there is an abnormality, simply releasing the lift switch 40 will stop the operation, which is safe.

In addition, in the embodiment, the support body 9 is removable from the bed frame 1, so that the guide rail 12 can be used at the site.
Even if there are errors in the construction materials, they can be assembled in a predetermined position in accordance with these errors. Moreover, in this case,
Support roller lO on which the wire 17 is suspended on the support body 9 itself
is provided, so even if the support body 9 is adjusted to protrude or retract, the tensioned state of the wire 17 when the wire 17 reaches the bed frame 1 from the support roller 10 does not change at all.
Therefore, the bed frame 1 can be smoothly moved up and down in any state. Furthermore, the wire 17 has a double-end supported structure in which one end thereof is locked to a locking tool 16 that is screwed and supported between the front piece of the auxiliary plate 15 and the bottom piece of the intermediate member 14. , which has the advantage of solidifying its support.

Note that the present invention is of course not limited to the above embodiments, and various safety devices may be omitted.

Furthermore, in the present invention, when the single winding mechanism is provided on the bed frame 1 side as in the above embodiment, the drive system including the winding device,
f! ! Although there are advantages such as easy inspection and maintenance of the air system, the present invention is not limited to this, and a single winding mechanism may be provided in the ceiling. Furthermore, a normal electric motor can be used, but the capacity of this motor must be such that it cannot be hoisted under the load of a person sleeping, and the electric motor's power supply circuit does not drive the motor for a predetermined period of time. If a timer mechanism is provided to turn off the power when the power is opened, this can also be used as a safety device. The power supply circuit for driving the motor is not the same as that of the above embodiment, and the electric motor may be configured such that, for example, the electric motor does not operate unless a push button switch is pressed to ensure awareness of its operation. good. It goes without saying that in various safety devices, the size, structure, etc. of the sensing body can be changed as necessary.

[Operations and Effects] In summary, since the present invention is constructed as described above, the bed frame can be moved to the lowered position where sleeping is possible and to the ceiling side while maintaining the horizontal position by the forward and reverse drive of the electric motor. Therefore, if the bed frame is stored on the ceiling side when not in use, the effective indoor space of the nine rooms can be widened, and the bed frame becomes a hindrance. You can live a comfortable life with excellent livability. Moreover, since the bed frame is stored while maintaining a horizontal position, there is no problem such as the futon slipping off or the like. Furthermore, since the above-mentioned transformation of the bed frame is automatically carried out by an electric motor, the winding and unwinding of each wire is uniform and the horizontal position can be maintained reliably, preventing the bed from tipping. This means that the transformation operation can be performed reliably over a long period of time.

Furthermore, in such a device, if a wire slack detection mechanism is installed and the electric motor is stopped when the wire is slack when the bed frame is lowered, the bed frame in the lowered position will be As a result, there is no sense of instability as in the case of wire support, and firm support is provided, ensuring a sound sleep.

In addition, regarding the safety associated with electric movement of the bed frame, if the guard handrail is raised to prevent the sleeper from falling, the system will detect this and restrict the drive of the electric motor. When such a safety device is provided, even if the drive switch of the sheet metal electric motor is opened, the bed frame will not rise, resulting in extremely high safety. Furthermore, in this case, the guard rail, which must be placed in an upright position when sleeping, serves as a detection object for the safety device, making it extremely reliable and reliable.

Furthermore, in the case where the safety device is configured to stop the electric motor by pushing up a detection body installed on the ceiling side, if the bed is raised with an obstacle on the bed frame, the corresponding The electric motor will automatically stop when the sensing object is pushed up by an obstacle.
Therefore, it is possible to prevent an obstacle from being caught between the ceiling and the bed frame, thereby improving safety.

Furthermore, in the case where the safety device is configured to stop the drive of the electric motor by pushing up a detection body provided on the bottom of the bed frame, when the bed frame is lowered, there is an obstacle between the bed frame and the floor. Even if the obstacle is between the floor and the bed frame, the presence of the obstacle is reliably detected and the electric motor is stopped to prevent the obstacle from getting caught. This will prevent them from getting caught between them, improving safety.

Some safety devices are designed to emergency stop the electric motor by pressing a detection body installed on the side plate of the bed frame, so if there is an obstacle while the bed frame is moving, When this is detected, the electric motor is stopped and the bed frame is stopped by pressing the detection body with a hand or the like. In addition, since this detection body is provided on the side plate of the bed frame, it can be formed so as to surround the bed frame all around it, thereby providing excellent response in an emergency and ensuring safety in one action.
