Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottom mounting mechanism for a bed which can be assembled without tools, particularly for a bed for home use.

[0002]

2. Description of the Related Art In recent years, the ratio of elderly people in Japan has been increasing steadily, and the necessity of home care has become increasingly prominent. Therefore, the demand for home beds is increasing. Since such a home bed is used in ordinary households, it is desirable to use an assembling bed. This is because when assembled, it is easy to pack and the size of the package can be reduced, so that it can be easily carried indoors.

[0003]

[Problems to be Solved by the Invention] However, on the other hand,
If it is an assembly type, it takes time and effort for assembling, and since it is assembled with reference to the instruction manual, it is not only complicated, but a tool is often required depending on the assembly location. The present invention has been made in view of such a background, and an object thereof is to provide a bottom mounting mechanism in a bed that allows the bottom to be assembled without tools.

[0004]

In order to solve the above-mentioned problems, the present invention is a bottom mounting mechanism for detachably mounting a bottom on a side frame of a bed, wherein the side frame has a recessed portion at the top. A bottom receiving metal fitting having a groove-like receiving groove and a bottom fixing metal fitting provided so as to overlap with the bottom receiving metal fitting. Attached to the metal fitting, the upper part is adapted to the upper part of the bottom receiving metal fitting, and there is a sloped part that is inclined on the upper part, and a locking hole is provided just below the sloped part so as to match the bottom groove of the bottom receiving metal fitting. , The bottom surface of the bottom to be attached is provided with protrusions at both ends in the bed width direction, which are engaged with the engagement holes, and these protrusions are brought into contact with the inclined portion of the bottom fixing bracket. , The bottom fixing bracket is pushed outward against the resilience, the projection is pushed into the bottom of the receiving groove of the bottom receiving bracket, and the bottom fixing bracket is locked in the locking hole just below the inclined section. It is a thing.

[0005]

[Function] While the projection on the bottom surface of the bottom to be attached is brought into contact with the inclined portion of the bottom fixing bracket, the bottom fixing bracket is pushed outward against the elastic force, and the projection is formed in the receiving groove of the bottom receiving bracket. The bottom can be fixed to the side frame by being pushed into the bottom and being locked in the locking hole just below the inclined portion of the bottom fixing bracket.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a bottom mounting mechanism in a bed according to the present invention will be described below with reference to the accompanying drawings, with reference to an embodiment. FIG. 1 shows an assembling type home bed 1. In this bed 1, the frame 2 is divided into three, and the headboard 3 and the footboard 4 are divided into the frame 2
It has a structure in which the bottom 5 is detachably attached, and the bottom 5 is divided into four, and two are connected to each other. Ie bottom 5
Is a combination of the back bottom 5a and the waist bottom 5b,
The knee bottom 5c and the leg bottom 5d are connected to each other. The three-divided frame 2 is composed of a head-side frame 2a to which the headboard 3 is attached, a frame 2b located at the center and corresponding to the waist, and a leg-side frame 2c to which the footboard 4 is attached. There is. The frame 2b located in the central portion has a head-side frame 2a and a leg-side frame 2 at both ends.
It is configured so that it is inserted into c and connected (see FIG. 2).

A bottom mounting mechanism 6 for removably mounting the bottom 5 is provided on the frame 2b located at the center. Such bottom mounting mechanism 6
Has a frame-shaped bottom receiving metal fitting 7 on the side end surface of the frame 2b, and a bottom fixing metal fitting 8 provided so as to overlap the bottom receiving metal fitting 7 (see FIG. 3). The bottom receiving member 7 is a receiving portion 7 for receiving the waist bottom 5b.
a and a receiving portion 7 for receiving the support frame 9 of the knee bottom 5c
b and. These receiving portions 7a and 7b are
The bottom receiving fitting 7 projects upward from the peripheral portion, and recessed receiving grooves 10 and 11 are formed in the upper portion.

On the other hand, the bottom fixing member 8 has the receiving portion 7
It is provided so as to overlap with a and 7b (see FIG. 4). That is, the bottom fixing member 8 is provided near the lower portion with the receiving member 7 by the screw 13 via the spring member 12.
It is attached so as to elastically overlap a and 7b.
Further, the bottom fixing metal fitting 8 has an upper portion for receiving portion 7a,
7b corresponds to a height position, and has an inclined portion 14 whose upper portion is inclined so as to open to the outside. Immediately below the inclined portion 14, the recessed receiving grooves 10 and 11 are aligned with the bottom portion. The locking hole 15 is formed.

Next, a support plate 16 is provided on the lower surface of the bottom 5 to be attached by the bottom attachment mechanism 6 near both ends in the width direction of the bed 1 (see FIG. 5). Receiving part 7 in metal fitting 7
Protrusions 17 for engaging with the receiving grooves 10 and 11 of a and 7b and the engaging hole 15 of the bottom fixing member 8 are provided. These protrusions 17 are brought into contact with the inclined portion 14 of the bottom fixing member 8, and the bottom fixing member 8 is pushed outward against the elastic force to open the protrusions 17 in the receiving groove 10 of the bottom receiving member 7. , 11 while being pushed into the bottom portion of the bottom fixing member 8 and locked in the locking hole 15 immediately below the inclined portion 14 of the bottom fixing member 8.

In the bottom mounting mechanism 6 as described above, the protrusions 17 on the lower surface of the bottom 5 to be mounted are aligned with the positions of the receiving portions 7a and 7b of the bottom receiving metal fitting 7 (see FIG. 6), and the bottom fixing metal fitting 8 is inclined. The bottom fixing bracket 8 is brought into contact with the portion 14 and pushed downward.
Is pushed outward against the resilience of the spring member 12 (see FIG. 7), the protrusion 17 is pushed into the bottoms of the receiving grooves 10 and 11 of the bottom receiving metal 7, and the bottom fixing metal 8 The bottom 5 can be fixed to the frame 2 by engaging with the engaging hole 15 just below the inclined portion 14 (see FIG. 8).

[0011]

As described above, according to the present invention, the bottom can be detachably attached to the bed without tools.
