An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view, partly in section, of a bed apparatus according to an embodiment of the present invention. The base 1 is formed in the shape of a rectangular box having an open upper surface, and the inside thereof is a storage section 2 for small items.

As shown in FIGS. 3 and 4, on the upper surface of the base 1, there is placed a cushion body 3 having a rectangular shape in plan view, the length and width being larger than those of the base 1. ing. The cushion body 3 includes a frame 4 and the frame 4
And a cushion portion 6 provided integrally with the frame 4 on the mounting plate 5. The frame 4 may be either a wooden frame or a metal frame, but in this embodiment, a wooden frame is used.

The frame 4 has a reinforcing bar 4b provided in a lattice shape in an outer frame 4a. The cushion unit 6 has a spring unit 7 mounted on the mounting plate 5 described above.
The spring unit 7 includes a number of coil springs 8
Are arranged in a matrix, the lower end surfaces of the coil springs 8 are fixed to the mounting plate 5 by a tacker (not shown), and the upper end surfaces of adjacent coil springs 8 are connected by a helical wire (not shown). The upper surface and the outer peripheral surface of the spring unit 7 are covered with an exterior body 9.

Although not shown in detail, the exterior body 9 is formed of a cushion material and a cloth. When the bed apparatus is used, the exterior body 9 is covered with a sheet 10 as shown in FIGS. , Bed making.

As shown in FIG. 1, the brackets 13 constituting the hinge mechanism 12 are located at both ends in the longitudinal direction of one side surface 1a in the width direction of the base 1 and slightly below the upper end in the height direction. Is attached and fixed.

The bracket 13 has a strip-shaped mounting piece 14 mounted and fixed to the side surface 1a.
Has a support piece 15 bent at a substantially right angle at one end thereof and a support shaft 16 protruding from the support piece 15.

The support shafts 16 of the pair of brackets 13 protrude outward from both longitudinal ends of the side surface 1a. That is, the support shaft 16 protrudes outward from both end surfaces in the longitudinal direction of the base 1. Each support shaft 16 is provided with an arm 17 rotatably fitted with a support hole 18 provided at one end. One end of the arm 17 in which the support hole 18 is formed is formed in a bent portion 19 which is bent substantially downward in a downward direction.

The arm 17 is formed of a rigid metal such as aluminum or steel in the shape of a rectangular tube, and the straight portion 20 other than the bent portion 19 is formed in the longitudinal direction of the lower surface of the frame 4 of the cushion 3. It is joined to both ends in the width direction along the width direction, and is fixed by screws or the like (not shown). The arm 17 has a length substantially equal to the width of the base 1 as shown in FIG. As a result, the tip of the arm 17 is located inside the end face of the cushion body 3 in the width direction by a predetermined dimension.

A cylinder chamber 22 is defined at both ends in the longitudinal direction of the base body 1 by partitioning plates 21 extending over the entire length in the width direction. Each cylinder chamber 22 is provided with a gas spring 23. As shown in FIG. 3, one end of the gas spring 23 is connected to the cylinder chamber 22 of the base 1.
The other end is pivotally attached to a lower bracket 24 provided on an inner portion, and the other end is pivotally attached to an upper bracket 25 provided on the lower surface of both ends in the longitudinal direction of the frame 4.

The gas spring 23 is in a contracted state against the restoring force when the cushion body 3 falls down and the upper surface opening of the base 1 is closed, and the cushion body 3 is connected to the support shaft 16 of the hinge mechanism 12. When the fulcrum is rotated in the ascending direction, it is extended by the restoring force.

Therefore, the cushion body 3 can be lifted with a lighter force than its own weight when it is turned in the upright direction, and is prevented from suddenly turning by its own weight when it falls down.

According to the bed apparatus constructed as described above, the hinge mechanism 12 for rotatably attaching the cushion body 3 to the base 1 is replaced by the bracket 13 having the support shaft 16.
And an arm 17 provided so as to be rotatably fitted to the support shaft 16 at one end thereof, and a linear portion 20 of the arm 17 is formed on the frame 4 of the cushion body 3. The lower surfaces at both ends in the longitudinal direction were fixed along the width direction.

For this reason, the cushion body 3 is
When the cushion body 3 is rotated, the frame body 4
Can be prevented from being distorted. That is, since the frame body 4 is reinforced by the arm 17, it is possible to prevent the frame body 4 from being distorted when rotated or damaged due to repeated use.

The arm 17 is joined and fixed to the lower surface of the frame 4. That is, the cushion body 3 is formed in a planar shape larger than the base 1, and the support shaft 16 of the hinge mechanism 12 is projected from both end faces in the longitudinal direction of the base 1, so that the arm 1
7 can be joined and fixed to the lower surfaces of both ends in the longitudinal direction of the frame 4.

Thus, the hinge mechanism 12 can be provided so as not to protrude outward from both longitudinal end faces of the cushion body 3, so that not only the appearance of the bed apparatus is improved, but also when the cushion body 3 is rotated. And arm 17
It is also possible to prevent clothes and the like from being hooked.

Since one end of the arm 17 is formed in the bent portion 19 and is separated from the lower surface of the frame 4, and the tip of the arm 17 is located more inward than the widthwise end surface of the cushion 3, At the time of bed making, the periphery of the sheet 10 covering the cushion body 3 can be securely engaged with the lower surfaces of both ends in the width direction of the frame body 4.

The sheet 10 is usually provided with a rubber string provided on the periphery thereof, and the rubber string is engaged with the lower surface of the frame so as to cover the cushion 3. Therefore, bed making can be performed by engaging the peripheral edge of the sheet 10 with the lower surface of both ends in the width direction of the frame 4 as described above.

In other words, even if the sheets 10 cannot be securely engaged with the lower surfaces at both ends in the longitudinal direction of the frame 4, if they can be engaged with the lower surfaces at both ends in the width direction, bed making becomes possible.

By increasing the length of the frame 4 in the longitudinal direction and projecting the lower surface of the frame 4 outward from the arm 17, the sheets 1 can be extended over the entire length of the lower surface of the frame 4.
0 can be engaged.

The present invention is not limited to the above embodiment. For example, in the above embodiment, the cushion body is provided so as to be rotatable along the width direction of the base. May be provided so as to be rotatable along the longitudinal direction. Also in this case, if a hinge mechanism having the same configuration as that of the above-described embodiment is used, the frame of the cushion body can be reliably reinforced.
