DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underfloor storage device for hall equipment such as a multipurpose hall, an exhibition hall, a warehouse, etc., for storing hall equipment such as chairs and tables under the floor so as to be freely taken in and out.

[0002]

2. Description of the Related Art In multipurpose halls, exhibition halls, warehouses and the like, hall facilities such as chairs and tables are used, but these hall facilities are stored in a storage room when not needed. In recent years, under the floor has often been used as the storage room. Hereinafter, a conventional underfloor storage device for hall equipment will be described.

FIG. 5 is a front view of a conventional underfloor storage device of a hall facility. In the figure, reference numeral 1 denotes a floor of a facility such as a multipurpose hall, an exhibition hall, a warehouse, etc., and a storage room 2 is recessed in the floor 1. Reference numeral 3 denotes a storage unit which is stored inside the storage room 2 so as to be able to move up and down. The storage section 3 is constructed in a box shape by an upper girder 4 and a lower girder 5 and the like, in which a chair, a table (not shown), and the like are stored.

The storage section 3 is supported by a pinion rack mechanism described below so as to be movable up and down. That is, reference numeral 6 denotes a long case which is provided upright at the lower part of the storage room 2, and the rack 7 is stored therein. The rack 7 supports the storage section 3 from below at its upper end. Reference numeral 8 denotes a pinion that engages with the rack 7 and is driven by a motor (not shown) to rotate. Reference numeral 9 denotes a guide rail for guiding the storage section 3 up and down.

Therefore, the motor is driven forward to rotate the pinion 8
When the is rotated forward, the rack 7 rises, and the storage section 3 rises above the floor 1 (see the storage section 3 on the left side shown by a chain line and the storage section 3 on the right side shown by a solid line in FIG. 5). With the storage unit 3 raised above the floor 1, a chair, a table, and the like are put in and out of the storage unit 3. When the motor is reversely driven, the pinion 8 rotates in the reverse direction, the rack 7 descends, and the storage section 3 descends into the storage chamber 2. In a state where the storage unit 3 is stored in the storage room 2, the height of the upper surface 4a of the upper girder 4 is at the same level as the floor 1, and the upper surface 4a also has the same floor surface as the floor 1, and the upper surface thereof And vehicles pass by.

[0006]

In FIG. 5, D1 is the depth required for installing the pinion rack mechanism, but this depth D1 is considerably large, and therefore the floor 1 must be excavated so deeply. . However floor 1
Drilling deeper will increase construction costs. In many cases, it is desired to construct the room A below the storage room 2, but the construction of the room A becomes difficult due to the obstacle of the pinion rack mechanism. Specifically, when the floor 1 is the first floor, it is difficult to construct a basement below the storage room 2, and when the floor 1 is the second floor or more, the ceiling of the room below the floor is abnormal. There was a problem that it became low.

Therefore, according to the present invention, the height of the lifting mechanism is lowered in order to raise and lower a storage section such as a chair or a table.
An object of the present invention is to provide an underfloor storage device of a hall facility that can effectively use a lower part of a storage room.

[0008]

For this purpose, the present invention provides a feed screw 25 which is vertically provided inside a storage chamber 12 which is recessed in a floor 11, and a drive unit 20 which rotates the feed screw 25. And this feed screw 2
The nut 26 moves up and down along the feed screw 25 by the forward and reverse rotation of the nut 5, the vertical pipe 28 into which the feed screw 25 is inserted, and the upper member 14 having the same level as the floor 11. Constituting the storage unit 13 of the hall equipment,
A pipe 28 is erected on the lower member 15 of the storage section 13,
In addition, by supporting the upper member 14 of the storage section 13 at the upper end of the pipe 28, the storage section 13 is moved up and down by raising and lowering the nut 26 so that the storage section 13 is moved into and out of the storage chamber 12. It was made.

[0009]

According to the above construction, the depth D2 for installing the elevating mechanism for raising and lowering the storage section 13 can be reduced, so that the lower part of the storage chamber 12 can be effectively used. Further, since the upper member 14 of the storage section 13 is supported by the pipe 28, the upper member 14 can withstand a large load.
A heavy vehicle can pass over it.

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of an underfloor storage device of a hall facility,
FIG. 2 is a side view of the same, and FIGS. 3 and 4 are partial front views of the same. In FIG. 1, reference numeral 11 denotes a floor, and a storage room 12 is recessed. The storage unit 13 is stored in the storage room 12. The storage unit 13 is constructed in a box shape from an upper girder 14 as an upper member, a lower girder 15 as a lower member, and the like, in which a chair, a table, and the like are stored. In a state where the storage unit 13 is stored in the storage room 12,
4a is a floor surface at the same level as the floor 11. In FIG. 1, the left storage unit 13 indicated by a solid line indicates a state in which the storage unit 13 is elevated above the floor 1, and the right storage unit 13 indicates a state in which the storage unit 13 is lowered into the storage chamber 12. .

Next, the lifting mechanism of the storage section 13 will be described. In FIG. 1, a motor 20 rotates a shaft 22 via a first gear box 21. Shaft 22
Extends horizontally from both sides of the first gear box 21, and a second gear box 23 is provided on the tip side thereof. In FIG. 2, 31 is a transmission gear box, and 32 is a transmission shaft. FIG.
3 shows the elevating mechanism when the device 3 is at a lower position (in a state of being stored in the storage chamber 12). 4 shows the lifting mechanism when the storage unit 13 is at the upper position (in a state where the storage unit 13 is raised above the floor 1).

Referring to FIG. 3, a feed screw 25 is provided upright on the second gear box 23. The feed screw 25 rotates when the motor 20 is driven. A nut 26 is screwed into the feed screw 25. Nut 26
Supports the support girder 27, and the support girder 27 supports the lower girder 15 of the storage unit 13. The feed screw 25 is inserted into a pipe 28. The pipe 28 stands on the lower girder 15, and the upper end of the pipe 28 supports the upper girder 14.

When the motor 20 is driven forward, its rotation is transmitted to the feed screw 25 via the first gear box 21, the shaft 22, and the second gear box 23,
5 rotates forward. Then, the nut 26 rises along the feed screw 25, and thereby the storage portion 13 also rises. FIG.
FIG. 1 shows a state in which the nut 26 has thus risen near the upper end of the feed screw 25 and the storage section 13 has risen above the floor 11 (in FIG. 1, the storage sections 13 and 13 indicated by solid lines on the left side). (See also the storage section 13 indicated by the chain line on the right). At this time, the upper surface of the lower girder 15 is at the same level as the floor 11, so that a chair, a table, and the like can be easily put in and out of the storage unit 13. When the motor 20 is driven in reverse, the feed screw 25 rotates in reverse. Then, the nut 26 descends along the feed screw 25, and the upper surface 1 of the upper spar 14
4a is at the same level as the floor 11 (in FIG. 1, the right storage section 13 indicated by a solid line).

That is, in this means, the support girder 27, the lower girder 15, and the pipe 28 are supported by the nut 26,
8, the upper beam 14 is supported, and the nut 26 is moved up and down along the feed screw 25, so that the storage section 13 is moved up and down.

According to the elevating mechanism, the installation depth D2
(See FIG. 1). Also, since the lifting mechanism composed of the feed screw 25 and the nut 26 has a large supporting force,
3 can carry a large number of heavy chairs and tables. Further, since the upper girder 14 is supported by the pipe 28 supported by the nut 26, even if a vehicle or the like passes on the upper girder 14 with the upper surface 14a of the upper girder 14 being at the same level as the floor 11, it is sufficient. Can be supported.

[0016]

As described above, according to the present invention, the depth D2 for installing the elevating mechanism for raising and lowering the storage section 13 can be reduced, and the lower part of the storage chamber 12 can be effectively used. The upper member 14 of the storage unit 13 is a pipe 2
8, the supporting strength is increased, and it can withstand a large load.
A large amount of chairs, tables, etc. can be stored in
4 allows heavy vehicles to pass.
