Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a bed device whose height can be changed with a simple operation.

[Technical background of the invention and its problems]

BACKGROUND ART So-called small beds such as baby beds are known as beds for sleeping children. Since children like to sleep next to their parents, the small bed is often installed on the side of the parent's bed, that is, the parent's bed. However, when a main bed and a small bed are installed side by side in a room, they occupy a large amount of indoor space, which has the disadvantage that they are very intrusive when not in use.

In order to eliminate this drawback, a small bed is formed to be able to rise and fall freely, and when not in use, is lowered and housed in a space under the floorboard of the main bed. As a bed that can be raised and lowered freely, it was built in 1983.
The one shown in Publication No. 1253 is known. In other words, this bed has a pair of legs that are pivotally connected at their midpoints, one end of which is pivotally connected to the bed frame, a moving shaft is attached to the other end, and one end of this moving shaft is attached to the bed frame. Insert into the lock guide hole of the lock lever which is pivotally connected to the lock lever. Upward engaging holes are formed at both ends of the lock guide hole, and when the moving shaft is engaged with these holes, the pair of legs are held in a laid down state or an upright state. It's summery.

By the way, in a bed device having such a structure, if the pair of legs are erected, that is, the bed is raised, and the lock lever is carelessly touched and rotated, the movement shaft may become engaged. There was a risk that the bed, which had been held in an elevated position after coming off the mating hole, would suddenly fall down due to the user's load.

[Purpose of invention]

The object of this invention is to provide a bed device that eliminates the risk of the bed held in an elevated state falling down even if the bed is inadvertently touched.

[Summary of the idea]

This device has a pair of legs that are pivotally connected at their midpoints, one end of one leg is pivotally connected to the lower surface of the bed base, and a pin provided at one end of the other leg is attached to the bottom of the bed base. a bed device that is slidably engaged with a guide hole formed on the lower surface, and that prevents the pin from sliding by having one end engage with a recess of an operating lever that is rotatably attached to the lower surface of the base; In this case, rotation of the concave portion of the operating lever in a direction in which the concave portion is removed from the pin is prevented by a stopper rotatably provided at the other end of the operating lever, and the stopper is prevented from rotating. Thus, even if the operating lever is touched inadvertently, the state in which the bed base is held by the operating lever will not be released.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings. The bed device shown in FIG. 1 includes a main bed 1 and a pair of small beds 2. The main bed 1 includes a floorboard 3, a headboard 4 and a footboard 5 that are attached to both ends of the floorboard 3 in the longitudinal direction and support the floorboard 3 at a predetermined height, and the floorboard 3.
It consists of a pinerest 6 placed on a pine tree. The small bed 2 has a width dimension that is approximately half that of the floorboard 3 of the main bed 1, and a floorboard 7 that is slightly shorter in length, a mattress 8 placed on the floorboard 7, and a support for the floorboard 7 such that it can be raised and lowered. Lifting mechanism 9 to be described later
It is composed of. The small bed 2 is housed in a space 10 on the lower surface side of the floor plate 3 of the main bed 1 in a lowered state, and when it is pulled out from this space 10 and raised, the mattress 8 of the main bed 1 It is designed to be supported at approximately the same height as the

The elevating mechanism 9 for the small bed 2 is provided with a pair of attachment members 11 (only one of which is shown) having an L-shaped cross section and each having one side attached to both longitudinal ends of the lower surface of the floor plate 7. The mounting member 11 has a length that is approximately the same as the width of the floor plate 7, and one end of the first leg 12 is pivotally connected to one end of the mounting member 11 by a support shaft 13. A middle part of the second leg 14 is pivotally attached to the middle part of the first leg 12 by a support shaft 15 . A pin 16 is provided protrudingly from one end of the second leg 14, and this pin 16 is slidably inserted into a long and narrow guide hole 17 bored at the other end of the other side of the mounting member 11 as shown in FIG. engaged. This pin 1
A first spring 18 is stretched between one end of the mounting member 6 and one end of the mounting member 11, and this spring 18 urges the second leg 12 in the upright direction shown by the arrow in FIG. It has been done. Note that the first and second legs 12,1
A roller 19 is rotatably provided at the other end of each of the rollers 4 . In addition, the guide hole 1 of the pin 16
The other end protruding from 7 is a first recess 21 or a second recess 2 formed in the middle of the operating lever 20, one end of which is pivotally attached to the middle of the mounting member 11.
2 to prevent rotation of the second leg 14. That is, when the first and second legs 12 and 14 are laid down as shown in FIG. This prevents the pair of legs 12, 14 from standing up, and in the erected state, engages with the second recess 22 to prevent the pair of legs 12, 14 from falling down. The other end of the operating lever 20 extends to one end in the width direction of the floor plate 7, and an operating shaft 23 is fixed at both ends between the other ends of the pair of operating levers 20 located at both longitudinal ends of the floor plate 7. At the same time, the interlocking shaft 24 is rotatably installed. A bush 26 fixed to the middle of a dogleg-shaped stopper 25 is externally fitted onto both ends of the interlocking shaft 24 projecting from the operating lever 20. One end located below this stopper 25 has a grip portion 2.
7 is provided, and the other end of the upper side faces an L-shaped locking piece 28 fixed to the mounting member 11.
Further, the stopper 25 is biased by a second spring 29 attached to the interlocking shaft 24 in a rotational direction such that the other end comes into contact with the locking piece 28 . Therefore, the stopper 25 is connected to the operating lever 20.
is prevented from rotating in the direction shown by the arrow in FIGS. 3 and 4, and the first or second recess 21, 2
2 and the pin 16 from being disengaged. In order to rotate the operating lever 20, the stopper 25 is rotated as shown by the chain line in FIG. Once removed, the actuating lever 20 can be rotated together with the operating shaft 23 to disengage the pin 16 from the recess. In other words, the pair of legs 12 and 14 can be raised and lowered freely. When the pair of legs 12 and 14 are erected to raise the floor plate 7, the floor plate 7 is held at approximately the same height as the floor plate 3 of the parent bed 1. Note that a third spring 30 is attached to a midway portion of the attachment member 11. This spring 30 is attached to a pair of legs 12,1
4 is compressed by these legs when laid down. Therefore, this third spring 30 urges the floorboard 7 in the upward direction by its restoring force. Furthermore, hooks 31 are rotatably attached to both widthwise ends of the lower surface of the floorboard 3 of the parent bed 1, as shown in FIG. This hook 31 can be engaged with a locking pin 32 protruding from the lower surface of the floor plate 7 of the small bed 2 when the small bed 2 is installed on the side of the main bed 1 in an elevated state. . This prevents the small bed 2 from shifting from the side of the main bed 1.

According to the bed device having such a structure, when the first and second legs 12 and 14 of the small bed 2 are erected as shown in FIG. 4, the small bed 2 can be moved as shown in FIG. If installed on the side of the main bed 1, the mattress 8 of the child bed 2 will be at almost the same height as the mattress 6 of the main bed 1, so the small bed 2 can be used conveniently.

Further, when the small bed 2 is not in use, the pair of legs 12 and 14 are laid down, and the floorboard 7 is laid down. In other words, after rotating the stopper 25 with one hand so that it is out of contact with the locking piece 28 as shown by the chain line in FIG. 5, the operating shaft 23 is rotated with the other hand while maintaining this state. The operating lever 20 is rotated upward together with the operating shaft 23. Then, the second recess 22 of this operating lever 20 and the second
Since the leg 14 is disengaged from the pin 16, the pin 16 slides through the guide hole 17 and the first and second legs 12, 14 fall down. Therefore, since the support height of the floor plate 7 of the small bed 2 can be lowered as shown in FIG. 3, it can be accommodated in the space 10 on the lower surface side of the floor plate 3 of the main bed 1. In other words, since the small bed 2 can change the support height of its floorboard 7 by the lifting mechanism 9,
It can be stored on the underside of the floor plate 3 of the main bed 1, and can also be used at almost the same height as the main bed 1.

Further, when the small bed 2 is raised or lowered, the actuating lever 20 may be accidentally touched. However, even if the operating lever 20 is touched and a force in the rotational direction is applied to it, the stopper 25 provided at this end comes into contact with the locking piece 28 and prevents the operating lever 20 from rotating. . Therefore, if the pin 16 is inadvertently disengaged from the first or second recesses 21, 22 of the operating lever 20, the small bed 2 which is in the raised state may be lowered, or if the small bed 2 is in the lowered state. first and third springs 18,
There is no such thing as going up with a resilience of 30. In other words, it is safe because the actuating lever 20 cannot be rotated until the stopper 25 is rotated.

[Effect of idea]

As described above, this invention uses a stopper to prevent rotation of the operating lever for maintaining the pair of legs in the upright or fallen state, and by rotating the stopper, the operating lever can be rotated. is now removed. Therefore, even if the actuating lever is inadvertently touched, the bed holding state is not impaired, and safety can be improved.
