However, in the above-described conventional type, the width A of the opening 82 is almost the same as the width B of the lid 83. Therefore, when a large article is taken in and out, the opening 82 is not closed. It is necessary to set the frontage dimension A to be large, and accordingly, the width dimension B of the lid 83 is also increased to the same extent. Thus, when the lid 83 is opened, the height H from the floor to the upper end of the lid 83 increases, and there is a problem that a large space is required in the height direction.

When the width B of the lid 83 is increased, the weight of the lid 83 also increases, so that there is a problem that a great deal of labor is required when the lid 83 is pulled up and opened. Further, when the storage 85 as described above is installed in a Japanese-style room, it is conceivable that a tatami 87 is attached to the upper surface of the lid 83, similarly to the tatami 86 laid on the floor plate 81. It is difficult to attach a handle or the like, and therefore, there is a problem that it is difficult to open the lid 83 from the closed position S.

According to this, the storage can be provided in the Japanese-style room, and by opening both lids, an opening approximately two tatami mats wide is formed. In addition, the lid can be opened and closed without disturbing a person entering or exiting the doorway. The storage in the third aspect of the present invention is provided with an auxiliary opening device that lifts at least one lid from the closed position and slightly opens the lid upward.

According to this, when opening the lid, first, at least one lid is lifted from the closed position and slightly opened upward by the auxiliary opening device. Then, the lid can be easily opened by grasping the edge of the slightly opened lid and rotating the lid upward, so that a handle or the like can be unnecessary. In the storage according to the fourth aspect of the present invention, a pair of auxiliary opening devices are provided, and both sides of the lid are lifted by the two auxiliary opening devices.

According to this, when the lid is opened, both sides of the lid are lifted from the closed position and slightly opened upward by the two auxiliary opening devices. Further, the storage according to the fifth aspect of the present invention is provided with an urging device for urging the lid in the opening direction, and when the lid slightly opened by the auxiliary opening device is further lifted upward, the urging force of the urging device is provided. Works to urge the lid in the opening direction.

According to this, when opening the lid, the lid is first lifted from the closed position and slightly opened upward by the auxiliary opening device. Next, by grasping the edge of the slightly opened lid and rotating the lid upward, the urging force of the urging device works to urge the lid in the opening direction, so open the lid lightly with a small force. Can be. In the storage according to the sixth aspect, a reinforcing member is provided on the back side of one end of both lids, and the auxiliary opening device is located between the reinforcing member of one lid and the reinforcing member of the other lid.

As shown in the figure, a plurality of tatami mats 62 are laid on the upper surface of the floor plate 3, and tatami mats 62a and 62b are also laid on the upper surfaces of both lids 7a and 7b, respectively. As shown in FIG. 14, both tatami mats 62a, 62 provided on both lids 7a, 7b are provided.
b is laid out so as to be located at a position (distant) from the entrance 63 of the room 1 by one tatami mat 62, and the direction I from the base end to the free end of both lids 7a, 7b. Are arranged so as to be substantially orthogonal to the entry / exit direction J of the entrance 63. Thus, a person who has entered the room 1 through the entrance 63 can put the article 64 in and out of the opening 4 while keeping the same orientation without changing the orientation of the body. Note that the entry / exit direction J may be set at the position of the virtual line (b) in FIG.

The operation of the above configuration will be described below.
When opening both lids 7a and 7b, first, by pressing the open switch 37 (see FIG. 14), as shown in FIG.
The electric motor 32 of the auxiliary opening devices 23 is driven to rotate forward, and one sprocket 31a rotates forward in the direction of arrow E, and the other sprocket 31b follows the one sprocket 31a and rotates forward in the direction of arrow E. As a result, the two chain bodies 26a and 26b are sent upward from the both retracting portions 29a and 29b to the upper limit position T.

At this time, one protruding piece 27a fits into the other concave space 28b, and the other protruding piece 27b fits into the one concave space 28a.
And the concave space 28a and the other protruding piece 27b and the concave space 2
8b mesh with each other to join one chain body 26a and the other chain body 26b, and the lifting member 24 is held in an upright state. Thereby, as shown in FIG.
a and 7b are lifted from the closed position S by a predetermined height h by the lifting members 24 of the auxiliary opening devices 23, and are vertically moved between the lids 7a and 7b and the adjacent tatami 62. A gap 65 in the direction is generated.

At this time, as shown in FIG.
When the second link 52a and the second link 12b rotate about the pin 67 as a fulcrum, and the third link 55 rotates about the pin 56 as a fulcrum, the first link 51 and the connecting link 57 swing. After the lids 7a and 7b are lifted in a horizontal position by a constant height G substantially corresponding to the thickness of the tatami 62,
As shown in FIG. 9, it is lifted diagonally upward.

Then, a hand is inserted into the gap 65 and the tatami 62
5 and 10, each of the lids 7a and 7b is rotated upward.
a, 7b are opened to the fully open position O. Thereafter, the article 64 is put in and out of the storage space 60 through the opening 4. In addition, since both ends 7a and 7b are configured in a double-opening manner in which one end adjacent to each other is turned upward and opened to the other end, the width dimension A of the opening 4 is set to each of the lids 7a and 7b. 7b width dimension B
, And the large article 64 can be put in and out without increasing the width B of each of the lids 7a and 7b. Therefore, when the lids 7a and 7b are opened to the full open position O, the height H from the tatami mat 62 to the upper ends of the lids 7a and 7b can be kept low. Thereby, the space required in the height direction can be reduced.

Further, as described above, the lids 7a, 7b
Is mechanically lifted from the closed position S by a predetermined height h by the lifting member 24 (see FIG. 4), and further, when a person lifts the lids 7a and 7b to open it to the fully open position O (see FIG. 5), Since the piston rod 16 of the spring 14 protrudes by gas pressure, the lids 7a and 7b are urged in the opening direction, whereby the lids 7a and 7b can be opened lightly with a small force. The protrusion of the piston rod 16 increases the resistance only in a certain initial range and reduces the urging force. In this range, as shown in FIG. 4, the lifting members 24 mechanically cover the lids 7a and 7b. Since it is lifted, no effort is required.

Then, as shown in FIG. 12, when the close switch 38 is pressed, the electric motor 32 of the auxiliary opening devices 23 is driven to rotate in the reverse direction so that the one sprocket 31a rotates in the direction of arrow F and the one Sprocket 31
a, the other sprocket 31b also reversely rotates in the direction of arrow F, and as a result, the two chain bodies 26a, 26b are moved from the upper limit position T to the two retracting portions 29a, 2 as shown in FIG.
Evacuate to 9b.

At this time, one protruding piece 27a is separated from the other concave space 28b and the other protruding piece 27b is separated from the one concave space 28a, so that one chain body 26a and the other chain body 26b are separated. Are separated in the left and right opposite directions and retreated in both retreating parts 29a and 29b in the lateral direction. Thereafter, the person rotates the lids 7a and 7b downward, thereby closing the lids 7a and 7b as shown in FIG. At this time, both lids 7a and 7b are in the closed position S,
The tatami mats 62a and 62b on the lids 7a and 7b are flush with the other tatami mats 62. When the lids 7a and 7b are rotated downward, the piston rod 1 of the gas spring 14
6 retreats against the urging force, so that the moment when both lids 7a and 7b rotate downwards is moderated, and the impact at the closed position S is buffered.

When both lids 7a and 7b are closed, one of the chain members 26a and the other chain member 26b are retreated in the retreating portions 29a and 29b in the lateral direction. The evacuation space is reduced in the vertical direction, so that the storage space 60 can be largely secured in the vertical direction. In addition, the tatami mat 6 of the closed both lids 7a and 7b is provided.
When a person or the like is placed on 2a, 62b and a load is applied,
This load is received by the support portion 18 and the lids 7a, 7b
Is reinforced by the reinforcing member 19, so that bending of the lids 7a and 7b due to a load can be prevented.

As shown in FIG. 14, both lids 7a, 7a
The two tatami mats 62a and 62b provided at the entrance b of the room 1
Since it is arranged at a position (distant) away from one by one tatami mat 62, the lids 7a and 7b can be opened and closed without obstructing a person entering or exiting from the entrance 63. Further, as shown in FIG. 8, the lids 7a and 7b are lifted in a horizontal position by a constant height G substantially corresponding to the thickness of the tatami mat 62 by the action of the link mechanisms 12a and 12b. As shown, it is lifted diagonally upward. Therefore, when the lids 7a and 7b are opened and closed, the degree of friction between the edges of the tatami mats 62a and 62b provided on the lids 7a and 7b and the edge of the adjacent tatami mat 62 is reduced, and wear of the edges of the tatami mats 62a and 62b is reduced. I do. In the initial process of lifting the lids 7a and 7b to the predetermined height h by the auxiliary opening device 23 as shown in FIG. 5, the lids 7a and 7b have a fixed height G by the action of the link mechanisms 12a and 12b as described above. It floats up in a horizontal posture, and has a relationship of predetermined height h> constant height G.

In the above embodiment, when the two lids 7a, 7b are opened, as shown in FIG. 4, the lids 7a, 7b are once lifted by a predetermined height h by a lifting member 24, and then the lids 7a, 7b are opened. Gap 6 between the tatami mat and the next tatami mat
