DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a frame structure in a bed or the like according to the present invention will be described with reference to the accompanying drawings while showing one embodiment. Figure 1,
FIG. 2 shows a bed 1 to which the frame structure according to the present invention is applied.
Shows the part on the side of the foot. The bed 1 is configured such that a main frame is supported on legs, for example, on a base frame (not shown), and a floor plate is held on the main frame. A foot-side frame 2 is shown, and a foot-side floor plate 3 is supported by the foot-side frame 2. In addition, the foot-side frame 2
The footboard 4 is attached to the end of the frame in the longitudinal direction of the frame, and a gap G is provided between the footboard 4 and the foot-side floor plate 3.
Is formed in this gap G, and this gap G
Further, a mattress holding frame 6 for holding the extension mattress 5 is protruded.

As shown in FIG. 3, the foot-side frame 2 has a pair of vertical frames 2a, 2a having a length L which determines and adjusts the entire length of the bed, that is, the entire length of the floorboard, and a horizontal frame having a size corresponding to the width of the floorboard. An accessory frame 7 is provided on both of the vertical frames 2a so as to protrude outward in the width direction of the floorboard.

The vertical frame 2a has an engaging portion 8 made of a synthetic resin at an end thereof facing the center of the bed so as to be detachably engaged with an intermediate frame of a main frame described later. . On the other hand, the accessory frame 7
A support fitting 9 for detachably mounting the foot board 4 is provided on an end portion corresponding to the bed foot side end portion of FIG. The accessory frame 7 and the vertical frame 2a are connected to each other by a connecting member 10 near an engaging portion 8 at an end of the vertical frame 2a facing the center of the bed.
The two accessory frames 7 are connected to each other by a reinforcing cross beam 11 in the vicinity of an end-side support fitting 9 corresponding to a bed foot-side end.

In addition, the accessory frame 7 relieves the impact when, for example, a wheelchair, a nursing care device, or another device collides with the outer end surface in the width direction of the frame.
A bumper 12 made of a soft synthetic resin is mounted to prevent both the wheelchair, the instrument side, and the bed from being damaged, and from being injured by a collision with a person. In addition, a plurality of mounting holes 13 for detachably mounting side fences and assisting members are formed on the upper surface of the accessory frame 7 at predetermined intervals.

The foot frame 2 constructed as described above
Corresponds to a case in which the physique (height) of the user is higher than usual. In a gap G formed between the footboard 4 and the foot-side floor plate 3, the mattress holding frame 6 protrudes. The extension mattress 5 is held, and the extension mattress 5 is interlocked with the foot-side floor plate 3 to be operated via a mattress holding frame 6 by a gatch operation. When the foot frame 2 configured as described above is replaced with a normal frame, the gap G between the foot board 4 and the foot floor plate 3 is eliminated, so that the mattress holding frame 6 is connected to the foot floor plate 3. And a mattress holding frame (not shown) of another size to be mounted on the foot-side floor plate 3 is attached.

The intermediate frame 20 in the main frame for detachably attaching the foot frame 2 configured as described above will be described with reference to FIGS. The intermediate frame 20 is located at the center of the bed, and holds a drive unit for adjusting the elevation of the floorboard and up / down movement, that is, a drive source 21 and links 22. In the intermediate frame 20, the width dimension of the pair of outer frames 23 in the bed longitudinal direction is set to be narrower than the width direction of the floorboard, and the vertical frame 2 a of the foot-side frame 2 corresponds to the intermediate frame 20. Outer frame 23
In addition, the structure is such that it is locked so as to be sandwiched from the outside in the width direction. That is, a pin member 24 for locking the locking portion 8 of the vertical frame 2a of the foot-side frame 2 on the side of the intermediate frame 20 and a bolt inserted through the bolt hole 25 formed in the vertical frame 2a. A screw hole (not shown) for screwing the bolt 26 is provided.

According to the frame structure of a bed or the like configured as described above, the foot frame 2 adapted to the height of the user is replaced and mounted to correspond to the height of the user. It can be used without problems even for tall people. As described above, since only the foot side frames 2 of different dimensional standards are exchanged and supported, the beds themselves need only be of one standard, and the production line equipment for beds of different standards is unnecessary. It is possible to maximize the use of a standard bed, leading to cost reduction.

The procedure for attaching the foot frame 2 to the intermediate frame 20 will now be described. The operator holds both accessory frames 7 of the foot-side frame 2 in his / her hands, and attaches the vertical frame of the foot-side frame 2 to the pin member 24 on the intermediate-portion frame 20 from diagonally above the head of the intermediate-portion frame 20. With the locking portion 8 of the vertical frame 2a facing the locking portion 8 of the vertical frame 2a, the locking portion 8 is engaged with the pin member 24 (see FIG. 5). Align the hole 25 with the screw hole on the intermediate frame 20 side, insert the fixing bolt 26, and use the hexagon wrench 2
7 and the like (see FIG. 6).

Then, the foot floor 3 is placed on the foot frame 2. At this time, when the foot-side frame 2 corresponds to a person who is taller than a normal person, a gap G appears between the foot board 4 and the foot-side floor plate 3, so that the gap G is covered. As described above, the mattress holding frame 6 can be protruded from the foot-side floor plate 3 to hold the extension mattress 5. Thereby, when the gatch operation is performed, the foot-side floor plate 3
Since the mattress holding frame 6 is interlocked with the actuation of the mattress, the extension mattress 5
(See FIG. 2), the discontinuity does not occur between the mattresses on the way, and the usability and appearance can be made uncomfortable.

[0014]

As described above, according to the present invention, since the frame is exchangeable, the external appearance is improved even when extended. Also,
When replacing the frame with an extended frame, the extended portion of the mattress is held by the mattress holding frame. The feeling of discomfort caused by the separation from the floor for use has been eliminated, and the sense of unity between the body and the mattress at the time of the gatch has been improved.
