DETAILED DESCRIPTION OF THE INVENTION A first embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, a fixed bracket 13 as a fixed base integrally provided with a mounting plate 12 on a floor surface 11 as a mounted portion in a push-in 10 as a storage portion.
Is fixed by a screw 12a inserted into a mounting plate 12, and the lower ends of a pair of parallel links 14 and 15 are rotatably connected to the fixing bracket 13 by pins 16 and 17 as shafts. At the upper end of these pair of parallel links 14 and 15,
An elevating bracket 23 as an elevating body is rotatably connected by pins 21 and 22 as shafts.

As described above, between the fixed bracket 13 and the lifting bracket 23, a pair of parallel links 14 and 15 are provided between the pins 16 and
Push-fit by connecting rotatably with 17, 21, 22
A link mechanism 20 is formed that rotates between an upright state inside 10 and a laterally laid state outside. This link mechanism 20
The four pins 16, 17, 21, 22 form a parallel movement mechanism in which a parallelogram is always maintained.

As an urging means for elastically urging the link mechanism 20 in the direction of the upright state against the weight of the stored object,
Between the fixed bracket 13 and the lifting bracket 23,
Both ends of the tension coil spring 25 are engaged and attached between the pin 16 and the pin 22 located on the shorter diagonal line of the link mechanism 20 in the upright state. The tension coil spring 25 is stretched from its natural length so that it can apply a necessary pulling preload between the pins 16 and 22 even when the parallel links 14 and 15 are in the upright state. Engage with.

As shown in FIG. 2, the link mechanism 20 includes
The lower storage part 10a of the push-in 10 which is partitioned by the shelf plate 26
A pair is provided along each of the left and right wall surfaces. This ensures a storage space between the left and right link mechanisms 20.

Further, a slide table 27 as a mounting table on which a futon F, which is a daily-use storage object, is placed is movably held between the upper portions of the left and right lifting brackets 23 in a fixed posture, that is, in a horizontal posture. It is inserted above the shelf plate 26.

The left and right lifting brackets 23 movably hold the slide table 27 by slide bearings 28 that hold the slide table 27 from above and below by a large number of rollers.

Since a handle 29 is provided on the front end surface of the slide table 27, if the handle 29 is held, the movable slide table 27 can be pulled out by the slide bearing 28 with one hand.

Since the link mechanism 20 can be completely housed in the push-fitting 10 by making a groove 26a into which the elevating bracket 23 is fitted in the shelf plate 26, a sliding door (not shown) can be closed. You can also

Next, the operation of the embodiment shown in FIG. 1 will be described.

When the futon F or the like is taken out from the push-in 10, first, the slide table 27 is pulled out horizontally from the shelf plate 26 so as not to interfere with the shelf plate 26 of the push-in 10, and then the parallel links 14 and 15 are erected upright.
