However, the above-mentioned conventional horizontal storage bed is bulky and heavy because the door and the bed frame are integrally fixed.
In order to pivotally connect the bed frame to the storage box, not only two or more workers are required, but also the workability of assembling the bed is poor.

Further, the above-mentioned conventional bed has a configuration in which a reaction force is accumulated in a tension spring by utilizing a displacement amount generated during a rotational movement of a bed frame. Therefore, the bed is rotated upright to a predetermined position. Beyond the angle, the impact due to the sudden closing operation of the bed does not perform a smooth closing operation, or an excessive force is applied between the components of the bed, causing a failure. .

[0005] Furthermore, the bed is rotated to the near side,
After the predetermined opening angle, the bed is suddenly opened, and the legs violently hit the floor or the like, which is not only dangerous, but also causes the legs and components to pivotally connect with each other. Are easily damaged by impact.

In addition, a tension spring is stretched between the bed frame and the storage box.

[0007] With the above configuration, only the door is pivotally attached to the storage box alone, and a separate bed frame is placed on the door, and then both are pivotally attached to each other at the front part. It is an object of the present invention to assemble the bed and thus to assemble the bed by one person easily and with good workability, thereby improving productivity.

According to a second aspect of the present invention, in addition to the configuration of the first aspect, a stopper for preventing sudden closing is rotatably supported at the lower rear end of the back surface of the bed frame. A tension spring is stretched in between, and a biasing force is applied to the stopper in a direction away from the rear end of the bed frame, so that the stopper comes into contact with the floor surface when the bed is closed. The stopper is rotated against the tension of the tension spring, so that the closing operation of the bed is performed gently, and the impact when the bed is closed is reduced.

According to a third aspect, in addition to the configuration of the first aspect,
At the rear end of the left and right sides of the back of the bed frame, by providing a slidable projection that comes into contact with the rollers provided on the inner surfaces of the left and right walls of the storage box, the opening operation of the bed is performed gently. ing.

And a left and right front part of the bed frame and a left and right front part of the back of the bed frame are pivotally connected to each other.

According to a second aspect of the present invention, in addition to the configuration of the first aspect, the lower part of the rear end of the back surface of the bed frame abuts on the floor surface when the bed body is closed. A stopper for preventing sudden closing is pivotally provided so as to be rotatable toward the rear end of the bed frame, and the stopper is provided with a tension spring for urging a rotational force in a direction opposite to the rotational direction by a tension spring. , And its content.

According to a third aspect of the present invention, in the configuration of the first aspect, the opening speed of the bed main body can be reduced at the right and left rear end portions of the back surface of the bed frame during the closing operation of the bed main body. A configuration is provided in which a protrusion that presses against the roller protrudes.

[0013]

According to the first aspect of the present invention, the bed frame can be rotated about the pivot point at the rear end of the bed frame integrally with the door, so that the front end of the bed body in the width direction is pulled upward. At this time, the rear ends of the left and right sides of the back of the bed frame are rotated and erected while sliding downward on the storage box by rollers supported on the storage box, and the bed body is stored in a horizontal standing state. The door is closed as soon as it is stored in the box, and the front opening of the storage box is closed. In addition, since the tension of the tension spring acts in the direction in which the bed main body rotates and rises, the bed main body can be rotated and raised by a light operation.

When the front end of the bed body in the housed state is pulled down to the near side, the bed frame is rotated forward while sliding upward by rollers, and the legs protruding from the front of the door come into contact with the floor surface. The bed body is held in a horizontal use state. In addition, the tension spring is extended by the forward rotation of the head frame, whereby the reaction force required when the bed is stored is accumulated.

In the horizontal storage bed according to the second aspect, when the bed body is rotated upright as described above, the stopper abuts against the floor surface and is rotated against the tension of the tension spring. Thus, the bed body is slowly rotated and raised, and the impact when the bed is closed (during storage) is reduced.

In the case of the third aspect, when the bed body in the housed state as described in the first aspect is pulled down to the front side, the bed frame is rotated forward while sliding upward by the rollers, and reaches a predetermined angle. When rotated,
The roller is pressed against the roller by a protrusion projecting from the rear end of the back of the bed frame, and is further slid on the roller. Will be performed slowly.
