Description

[Detailed explanation of the idea] The present invention relates to a folding bed.

Various types of folding beds have been proposed, which stand upright along a wall when not in use, and are placed on the floor with a rotating source only when in use.However, most of these use coil springs, and they do not allow the bed to thump or slam when it is rapidly accelerated. There is a possibility that it will break.

Therefore, recently, devices using gas springs have been proposed.

Bed frames using gas springs have the advantage of smooth acceleration without sudden acceleration, but recently there has been an increase in requests for lowering the height of the bed frame from the floor, and the relationship with the thickness when standing upright has increased. However, if the device is placed flush against the wall surface, a gap will be created between the device and the wall surface during use, which has become a very serious problem.

The purpose of the present invention is to provide a folding bed that can solve the above problems.

The structure of the present invention will be explained in detail based on the embodiment shown in the drawings.A U-shaped head frame 2 is installed along a wall surface 1 so that the open side is located on the opposite side.

This head frame 2 has rear aggregates 3 vertically installed on both sides,
A horizontal top plate part 4 is provided protruding from the upper end of the rear aggregate 3, and the top plate part 4
An upper vertical part 5 is provided by bending the end of the upper vertical part 5 vertically downward, and an inclined part 6 is formed by protruding the lower end of the upper vertical part 5 toward the side opposite to the wall surface, and then a lower vertical part 7 is formed vertically downward. Aggregate 8 is provided.

Further, an outer surface closing plate 9 is fixed to the entire outer surface of the rear aggregate 3 and front aggregate 8 on both sides, and an inner surface closing plate 10 is fixed to the inner surface at the upper end 1 of the lower vertical part 7, respectively, to form a hollow structure.

Further, the headboard 11 is fixed across the rear aggregates 3, 3 on both sides.

A support piece 12 is provided on the inner side of the center extending in the height direction of the lower vertical portion 7 of each of the front aggregates 8, 8 on both sides to protrude toward the wall surface, and a roller 13 is rotatably mounted on each of the support pieces 12 and 12. It is pivoted.

On the other hand, the bed frame 14 on which the mat A is placed has channel-shaped guide members 15 and 15 on the lower surface of both sides on the wall side.
(see FIG. 4) is fixed, and the rollers 13 and 13 are fitted so that the rollers 13 and 13 can move under the guidance of the rollers 13 and 13.

Further, as shown in FIG. 5, L-shaped brackets 16.16 are fixed to the upper surfaces of both sides of the wall side of the bed frame 14 so as to protrude outward, and boot run-shaped brackets are respectively fixed to the upper ends of the brackets 16.16. One end of the link 17 is pivotally connected.

The other ends of the links 17 on both sides are pivotally connected to support pieces 18 protruding from the upper end wall surfaces of the lower vertical portions 7 of the front aggregates 8, 8, respectively.

A branch piece 19 is provided protruding from the upper end of the center side of the link 17, and a branch piece 19 is provided on the top plate portion 4 of each of the front aggregates 8, 8.
The rod 22 of the gas spring 21 is pivotally connected via the 0.

In the figure, reference numeral 23 indicates folding legs attached to the bed frame 14, and reference numerals 24 and 25 indicate mat support members.

The embodiment of the present invention is constructed as described above, and when the bed is in use, the bed frame 14 is in a horizontal position as shown by the solid line in FIGS. 2 and 3.

At this time, the rollers 13 and 13 are respectively guided by 15° and 15°.
0 is located at the opposite end of the wall.

When the bed is not in use, the folding legs 2 of the bed frame 14
If you hold the 3 side and rotate it upward, the gas spring 21
The rod 22 is pulled out, and the bed frame 14 stands up.

During this standing up, the bed frame 14 moves toward the guide member 15.1.
5, the guide member 15.15 rotates while changing the contact position with respect to the roller 13.13, and when it stands up, the head side end of the guide member 15.15 contacts the roller 13.13, as shown by the chain line in FIG. become.

In the above embodiment, the link 17 was described as being formed in a Hoomerang shape, but the shape is not limited, and various shapes can be used.

Alternatively, it may be formed by combining two plate-like bodies.

In addition, although it was explained that the head frame 2 is formed in a U-shape,
The present invention is not limited to this, and it is sufficient that frames exist on both sides.

Since the present invention has the above-described structure and operation, the center of rotation of the bed frame 14 moves, so that there is no gap between the bed frame 14 and the wall or headboard, etc., even when the bed is in use or not in use. This does not occur, there is no need to take up a large space, and the bed can be lowered.

Further, since the gas springs 21 are housed within the head frames on both sides, they are not exposed to the outside, and the appearance can be finished neatly.
