Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a retractable bed device that can be stored in a storage section when not in use.

(Prior Art) Generally, a retractable bed device is known as a bed device that does not occupy a large amount of indoor space when not in use. Conventionally, as a prior art of a retractable bed device, there is one disclosed in Japanese Utility Model Publication No. 52-41442. That is, in this prior art, one end of the bed is rotatably attached to the lower end of the storage section, and the legs are rotatably provided at the other end of the bed. When the bed is laid down, these legs rotate toward the bottom of the bed to support the bed almost horizontally, and when the bed is erected, they rotate toward the top of the bed so that they do not get in the way. In this state, the bed can be stored in the storage section.

(Problem to be solved by the invention) By the way, in a retractable bed device having such a structure, each time the bed is used or stored in the storage part, the legs are placed on the top or bottom side of the bed. The user must operate the bed and rotate the bed so that the bed rotates. Therefore, there was a problem in that the bed had very poor operability when in use or when not in use.

This invention was developed based on the above circumstances, and its purpose is to automatically rotate the legs in conjunction with the rotation operation of the bed, so that it can be easily adjusted when in use or when not in use. To provide a retractable bed device designed to improve operability.

(Means and effects for solving the problem) In order to solve the above problem, this invention includes a storage section with an open front, a bed whose longitudinal end is pivoted to the lower end of the storage section, The bed is provided at the other end in the longitudinal direction of the bed so as to be rotatable and biased in the upright direction by a first biasing member, and when the bed is laid down, it is raised by the biasing force of the first biasing member. a leg body that supports the bed substantially horizontally; an actuating plate provided above the opening surface of the storage portion so as to be openable and closable; and a second biasing member that urges the actuating plate in the direction of opening. is provided on the inner surface of the actuating plate, and is pushed out by the other end of the bed when the bed is erected and stored in the storage section, and the actuating plate is moved by the urging force of the second urging member. and a connecting member that is rotated in the closing direction against the
The leg pair is characterized in that it is folded against the biasing force of the first biasing member by the actuation plate that rotates in the closing direction. When the bed is laid down, the legs are erected to support the bed substantially horizontally by the first biasing member;
When storing the bed, the operating plate allows the bed to be folded down so as not to interfere with the storage.

(Example) An example of this invention will be described below with reference to the drawings. The retractable bed device shown in FIG. 1 has a storage box 1 as a storage section. The storage box 1 has an open front, and one longitudinal end of a bed 2 is rotatably connected to the lower portions of both sides of the storage box 1. In other words, as shown in FIG.
is attached. One end of a plurality of springs 5 is engaged with one end of the mounting plate 3 in the longitudinal direction. A connecting piece 6 is attached to the other end of these springs 5.
On the other hand, the bed 2 is composed of a frame 7 and a mattress 8 placed on the frame 7. Band-shaped mounting fittings 9 are provided on both sides of one end of the frame 7. The end portion of this mounting bracket 9 is pivotally attached to the mounting plate 3 by a support shaft 11, and the connecting piece 6 is pivotally attached to the midway portion.
Therefore, the bed 2 is biased in the upright direction by the springs 5, and can be tilted down as shown by chain lines in FIG. 2 against the biasing force of the springs 5. ing.

A leg body 12 made of a pipe material bent into a substantially U-shape is pivotally attached to the lower surface of the other longitudinal end of the bed 2. A spring 13 as a first biasing member is stretched between the pivot end of the leg 12 and the frame 7, and the biasing force of the spring 13 applies the biasing force of the spring 13 to the frame 7.
2 is biased in the standing direction. Therefore, when the bed 2 is laid down as shown by chain lines in FIG. 2, the legs 12 stand up and support the bed 2 horizontally.

An operating plate 14 is provided on the upper part of the opening surface of the storage box 1 so as to be openable and closable. This actuating plate 14 is the second
It is biased in the opening direction by a spring-type stay 15 as a biasing member. Further, an interlocking member 16 made of a rod material bent into a crank shape is provided on the inner surface of the actuating plate 14. This interlocking member 16 engages with the end of the frame 7 when the bed 2 is raised and stored in the storage box 1. Therefore, when storing the bed 2, the operating plate 1
4 can be rotated in the closing direction against the biasing force of the stay 15. When the actuation plate 14 is rotated in the closing direction, the leg body 12 is pressed by the inner surface of the free end side of the actuation plate 14, and the leg body 12 is folded against the biasing force of the spring 13. It can be done. In addition, when the bed 2 is completely stored in the storage box 1, the bent portion 16a of the interlocking member 16 comes into contact with the frame 7 of the bed 2, preventing the operating plate 14 from opening due to the biasing force of the stay 15. ing.

A cover plate 17 is attached to the underside of the frame 7 of the bed 2. When the bed 2 is stored in the storage box 1, the cover plate 17 and the operating plate 14 close the opening of the storage box 1. Furthermore, a grip 18 is provided on the cover plate 17. When the grip 18 is rotated,
An engaging lever 19 shown in FIG. 2 slides in the width direction of the bed 2, and its ends engage with engaging holes 21 formed on the inner surfaces of both sides of the storage box 1 to hold the bed 2 in an upright position.

According to the retractable bed device with such a structure,
When in use, when the bed 2 stored in the storage box 1 is lowered by operating the handle 18 as shown by the solid line in FIG. The bent portion 16a of the interlocking member 16 is removed from the frame 7 of the bed 2. Then, the actuating plate 14 opens as shown by the chain line in the figure due to the biasing force of the stay 15, and by opening the actuating plate 14, the contact state between it and the leg body 12 is released. Therefore, this leg body 12 is erected by the biasing force of the spring 13. That is, simply by lowering the bed 2, the legs 12 automatically stand up and support the bed 2 substantially horizontally, so that the operation during use is simple.

Further, when storing the bed 2 in the storage box 1 when not in use, the bed 2 is erected without folding the legs 2. Then, the interlocking member 16 engages with the end of the frame 7, and the actuating plate 14 is rotated in the closing direction against the biasing force of the stay 15. The body 12 will be folded. Therefore, there is no need to fold the legs 12 when storing the bed 2, and the operation is easy.

Note that this invention is not limited to the above-mentioned example,
For example, the shape of the interlocking member 16 does not have to be crank-shaped, and the point is that the actuating plate can be linked to the rotation of the bed, and when the bed is raised, the actuating plate can be held without being released by the biasing force of the stay. Any shape is fine.

(Effects of the invention) As described above, this invention allows the bed, which is stored in an upright position in a storage box, to be laid down, and the legs provided on the bed automatically stand up to support the bed. Furthermore, when the bed that has been laid down is erected and stored in the storage box, the legs are automatically folded. Therefore, since there is no need to operate the legs when using or storing the bed, operability can be improved.
