Abstract

PROBLEM TO BE SOLVED: To provide a variable seat device without subdividing a floor surface. SOLUTION: A pair of floor panels 2, 2 are continuously provided in a mountain shape to form floor members 1 and seats 3 are mounted to the surface of one floor panel 2 to arrange a plurality of floor members 1 in the longitudinal direction and support the respective floor panels 1 so as to be movable up and down and rotationally movable 90 degrees to the longitudinal direction. The floor members 1 having a level difference from the other members to avoid interference between each of the seats 3 and each of the other members are rotated in sequence from either longitudinal ones to cause two-way conversion between a parquet condition and a seat used condition. The floor members 1 are supported at a middle and so the need for subdividing the floor surface in the cross direction is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable seating apparatus for changing the floor of a theater, hall, or the like, between a flat-land state and a state in which guest seats are arranged according to an entertainment.

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open
The one described in Japanese Patent No. 24812 is conventionally known. In this apparatus, a plurality of flat floor members having seats fixed on one surface are arranged in the front-rear direction, and a plurality of these are arranged in parallel across a passage portion, and both ends of each floor member are provided below the passage portion. In addition to being supported by a bearing with a rotation drive mechanism so as to be rotatable by 180 °, the possibility of the rotation is switched by a lock pin protruding and retracting from the end face of the passage portion, and a lifting mechanism for raising and lowering each floor member is provided. ing.

[0003] In order to switch between a flat ground state and a seat use state by using this device, the lock of the floor member by the lock pin is released, and each floor member is moved so as to avoid interference between the seat and other members. And rotate 180 °.

[0004]

However, in the above-mentioned variable seat device, the floor member can be supported only at both ends, so that the floor surface is divided via a passage portion, and the floor member is placed below the non-reversible passage portion. Is provided. For this reason, the arrangement of seats and passages is restricted, and it is not possible to convert upholstery such as boards and carpets so that they are aligned over the entire floor, and there are many gaps on the floor, and the mechanism is complicated and cost is reduced. There is a problem of becoming high.

Accordingly, an object of the present invention is to provide a variable passenger seat device that can be inverted without subdividing the floor surface.

[0006]

In order to solve the above-mentioned problems, according to the present invention, a pair of floor plates are connected in a mountain shape to form a floor member, and a seat is attached to one of the floor plate surfaces. Are arranged in the front-rear direction, and each floor member is supported so as to be able to move up and down and rotate 90 ° in the front-rear direction, and these floor members are separated by other members so as to avoid interference between the seat and other members. In this state, a level difference is provided between them, and by sequentially rotating from either one of the front and the rear, bidirectional conversion between the flat ground state and the seat use state is performed.

[0007] With this configuration, since each floor member can be supported at the intermediate portion, there is no need to subdivide the floor surface in the width direction.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, FIG. 1 shows the state between the flat soil, FIGS. 5 and 7 show the state of using the seat, respectively, and FIGS. 2 to 4 show the transition process. FIG. 6 shows a state in which the seat is a corrugated floor.

In these figures, a plurality of floor members 1 arranged in the front-rear direction are formed by connecting a pair of floor plates 2 and 2 in a mountain shape, and a seat 3 is attached to the surface of one floor plate 2. I have. A stage S is provided in front of the floor member 1 in the front row, and a rear floor B is provided in the rear of the floor member 1 in the last row. The lifting mechanism of the lifting table 4 is of a cross arm type in the drawing, but may be of a jack push-up type or a spiral lift type.

A plurality of mounting members 5 are provided on the back side of each floor member 1 at intervals in the width direction, and each mounting member 5 has a support shaft 7 mounted on a support column 6 erected on a lifting platform 4. It is connected rotatably via the. The elevating platform 4 and the floor member 1 are connected by a rotation cylinder 8, and the floor member 1 can be rotated 90 degrees in the front-rear direction as it expands and contracts.

Now, in the above-described variable seat type apparatus, in order to switch from the flat-land state shown in FIG. 1 to the seat use state shown in FIG. 5, each floor member 1 must be moved as shown in FIGS. In order to avoid interference between the seat 3 and the other members, the seat 3 is sequentially rotated forward by 90 ° from the front member in a state where a height difference is provided between the members.

Conversely, in order to change from the seat use state to the flat ground state, the seat member is sequentially rotated backward by 90 ° from the rear floor member 1.

In addition, when the seat 4 is used, the elevator platform 4 is raised stepwise toward the rear, so that it is possible to provide a passenger seat as shown in FIG.

In the passenger seat variable device having the above structure, each floor member 1
Can be supported by the plurality of columns 6, so that the floor surface can be inverted without being subdivided in the width direction.

[0015] For this reason, compared to the above-mentioned conventional ones, seats and passages can be freely arranged, and it is possible to convert the upholstery such as boards and carpets so that they are aligned over the entire floor, and it is also possible to change the clearance between the floors. Also decreases.

Further, since the rotation angle of the floor member is 90 °, it becomes easy to supply power to the floor heating, the foot light, the simultaneous interpretation equipment, and the like attached to the customer seat.

Further, the number of the lifting / lowering / rotating mechanism is small, and the lock mechanism is not required.

[0018]

As described above, in the variable seat device according to the present invention, a seat is mounted on one surface of a plurality of mountain-shaped floor members arranged in the front-rear direction, and these floor members are raised and lowered to interfere with other members. By rotating 90 ° while avoiding the above, bidirectional conversion between the flat-land state and the seat use state is performed, so that each floor member can be supported at the intermediate portion.

For this reason, it is not necessary to subdivide the floor surface in the width direction, the degree of freedom in arranging seats and passages is improved, it is possible to convert the flooring materials so that they are aligned over the entire floor, and the clearance between the floor surfaces is reduced. Besides, since it is a simple mechanism, it can be manufactured at low cost.
