Expand and use. Known storage beds of this type are shown in FIGS. 9 and 10. In the storage beds illustrated in FIGS. 9 and 10, the bed frame c on the bed body a side has the connecting fitting c and the pins f and f ′.
The front side frame c ′ of the bed frame c is constituted by a front side frame c ′ and a rear side frame c ″ which are connected to each other through an opening (doorway) d.
Is placed on a door e that is pivotally attached to the lower side of the storage box b, or is directly attached to the lower side of the storage box b. In such a storage bed, when the bed frame c is folded in a U-shape shown by the solid line in FIG. 10 and is housed in the storage box b integrally with or separately from the door e as shown by the chain double-dashed line in FIG. 10, the mattress g Is sandwiched between the front and rear frames c ′ and c ″ in a folded state.

[Problems to be solved by the device]

In the case of the storage bed illustrated in FIG. 9 and FIG. 10, when the bed frame body c is folded as described above, the rear side frame c ″
Is pushed up in the direction of arrow h in FIG. 10 due to the elastic force of the mattress g, bedding (futon, blanket), etc., resulting in the state of the broken line in FIG. When the rear frame c ″ is pushed up in this way, that is, when the front and rear frames c ′ and c ″ are not completely closed and overlapped with each other, when the bed main body a is stored, the back plate in the storage box b is stored. The bedding slides into the frame housing space i generated between b'and the front frame c '. Particularly, as shown in FIGS. 9 and 10, when the headboard j and the headboard supporting actuating bar k are arranged in the storage box b, the rear end of the rear side frame c ″ abuts on them. The bed main body a cannot be stored, and even if the bed main body a can be stored, the bedding slides into the frame storage space i when the bed frame c is expanded, so that the operability at the time of storage and expansion is reduced. As a countermeasure, as shown in Fig. 10, both front and rear frames c ',
It is conceivable to hold the bed frame body c in the folded state via the tension spring l hung on c ″. However, in the case of this means, the front and rear side frames c ′ and c ″ are horizontally deployed. Since the strength of the tension spring l must be limited in consideration of the spring resistance at the time, the above-described folding and holding cannot be effectively performed, and in addition, a part of the bedclothes includes the tension spring l.
There are also cases where it is caught in or caught in.

Has a hook and a lever projecting from the rear end side of the actuating rod in a direction intersecting with the hook, and the projecting directions of the hook and the lever are substantially the same. An actuating rod rotatably attached to the hook projects the hook along the front end face of the front frame, and the lever is interposed between the connecting parts of the front and rear frames, so that it can be locked with the hook tip side. A corresponding locking tool is provided on the rear end surface of the rear side frame, and a pressing member for pressing down the lever when the front and rear side frames of the bed frame are unfolded is connected so as to collide freely with the lever. The actuating rod is equipped with a spring that is provided on the member and that applies a rotational force in the direction in which the hook is hooked on the locking tool.

[Action]

In the case of the storage bed according to the present invention, the front frame and the rear frame of the bed frame are flexibly connected through the connecting member, and the front frame of the bed frame is located below the front part of the storage structure. It is connected to up and down freely. Therefore, when the bed frame is stored in the storage structure, the rear frame is folded over the front frame, the front frame is raised, and these are put into the storage structure. At this time, the lever at the rear end of the operating rod on the back side of the front frame,
The pressing member attached to the connecting member is separated from each other, and the actuating rod is rotated in the predetermined direction (the direction in which the hook engages with the locking tool) by the force of the spring. It hangs on the locking tool provided on the rear end surface. That is,
The folded state of the front side frame and the rear side frame is locked by the hook and the locking tool that are locked relative to each other. When the storage bed according to the present invention is used, the bed frame is pulled out from the storage structure, and the front frame and the rear frame of the bed frame are expanded horizontally. When unfolding the front frame and the rear frame while pulling out the bed frame from the storage structure, the pressing member on the connecting member side collides with the lever in this operation process, and after the collision, the pressing member acts as a spring. By depressing the lever in the opposite direction (the direction in which the hook disengages from the lock), the hook at the front end of the operating rod disengages from the lock on the rear end surface of the rear frame.

[Effect of device]

The storage bed according to the present invention has the following effects. One of them is that when the front and rear side frames of the bed frame body are folded, the hooks on the front frame engage with the locking tools on the rear frame to lock this state.
When locked in this way, the rear frame does not float up from the front frame even if the reaction force of the mattress or other bedding sandwiched between the folded front and rear frames acts on the front and rear frames. Therefore, when the bed frame (front and rear frames) is folded and stored in the storage structure, and further, when the folded bed frame is pulled out from the storage structure and used. The rear end of the rear frame does not interfere with other members in the storage structure and the bedding between the front and rear frames in the folded state does not slide into the storage structure. The other is that the actuation rod, the lever, the spring, and the pressing member function effectively when the bed frame is folded, and the hooks and the locks are automatically locked to each other. That is, when the rear side frame is folded over the front side frame, the hook automatically engages with the locking tool, so that no special operation is required for this type of locking. Further, the other is that the operating rod, the lever, the spring, the pressing member, and the like are on the back side of the bed frame body, and the hook also sinks along the front end surface of the front frame in the unlocked state described above. Therefore, when the bed is used or when the bed is stored, there is no possibility that these members will become dangerous objects or obstacles in handling, and safety can be ensured.
