Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an inverted structure of a floor in which a chair is mounted in a theater, a hall or the like.

[0002]

[Prior Art]

 In the past, when the floor was used as a large flat surface in a dance hall, an event, an exhibition hall, etc. in a theater, hall, etc., the chairs placed on the floor were put away by human power or the like.

[0003]

[Problems to be solved by the device]

 However, it takes a lot of labor and time to clean up chairs by human power, and when using them again as theaters and halls with chair seats, it takes the same labor and time as before to set the chairs again. Needed. The present invention has been proposed in view of the above-mentioned problems of the prior art. The purpose of the present invention is to reverse the floor so that the chairs can be cleaned up and set automatically and easily and quickly to save labor. The point is to provide the structure.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, an inverted floor structure according to the present invention comprises a floor-approaching and a lift-up / down drive apparatus for the floor-approaching floor, a rotatably-supported top on the floor-top, and a chair on the upper surface. It is composed of a fixed floorboard and a rotary drive device for the floorboard. According to a second aspect of the present invention, a fixing pin hole is formed in the floor plate to which the chair is fixed, and a fixing pin that is engageable with and disengageable from the pin hole and a forward / backward drive device of the fixing pin are mounted near the floor. It is a cross.

[0005]

[Action]

 Since the present invention is configured as described above, when the chair is put away from the floor and the floor is to be used as a floor in a dance hall, an entertainment venue, etc., the floor approach is made through a lifting drive device. The floor board, which is supported by the top of the floor close to the floor in the raised position and has a chair fixed to the upper surface, is moved horizontally by operating the rotary drive of the floor board. By rotating 180 degrees around the axis, the upper surface of the floor plate to which the chair is fixed is located on the lower surface, and the upper surface is located on the smooth lower surface where the chair is not fixed.

At this time, since the floor plate is inverted at the raised position of the floor pressing, it is performed without being interfered with the adjacent floor pressing. After that, the floor pressure is lowered to its original position by an elevating drive device to form a smooth floor surface. According to a second aspect of the present invention, a fixing pin provided near the floor is fixed to a fixing pin hole provided on the floor plate by a forward / backward drive device for the pin, so that the fixing pin is rotatably mounted around a horizontal axis. The floor plate is fixed.

【Example】

 The present invention will be described below with reference to the illustrated embodiments. A indicates a foundation of the theater, and a plurality of floor presses B are arranged in the front-rear direction on the foundation A. The same floor approach B of each step is composed of a floor board a and a side end passageway b in the middle, and the upper end is pivotally supported by a girder 1 disposed in the middle of the floor approach B in the height direction and the lower end. A roller 2 which runs on the foundation A is pivotally attached to the middle of a link 3 which is pivotally supported, and a lower end is pivotally attached to an upper end of a link 4 which is pivotally supported on the foundation A. Further, a lower end of a hydraulic cylinder 5 is pivotally supported on the shaft 2 of the roller 2, and an upper end of the hydraulic cylinder 5 is pivotally supported on a passage portion b, and a hydraulic cylinder drive motor 6 is operated to extend and contract the hydraulic cylinder 5. By doing so, the floor approach B is configured to move up and down. Thus, the link 3 with the roller 2, the link 4, the hydraulic cylinder 5, and the hydraulic cylinder drive motor 6 constitute a lift drive device for the floor approach B.

A chair P is fixed to the upper surface of the floor board a, and a driven wheel 8 mounted on the horizontal rotation shaft 7 is supported by an extension of a horizontal rotation shaft 7 which is horizontally installed in the passage b. An endless belt 11 is bridged between a drive wheel 9 of a drive motor 9 mounted on the girder 1 and the floor plate a is configured to rotate about a horizontal axis by driving the motor 9. ing.

The horizontal rotary shaft 7, the drive motor 9, the drive wheels 10, the driven wheels 8 and the endless belt 11 constitute a rotary drive device for the floor board a. A fixing pin hole 12 is bored on the side surface of the floor plate a, and a fixing pin 14 that is moved forward and backward by a hydraulic cylinder 13 built in the passage portion b is configured to engage and disengage.

Since the illustrated embodiment is configured as described above, when the chair P is put away and the entire floor surface is used as a smooth surface to be used as a floor of an event hall or a floor of a dance hall, The cylinder 5 is actuated to raise the floor pressure B as shown by the dotted line in FIG. 1, after which the hydraulic cylinder 13 is actuated to pull out the fixing pin 14 from the fixing pin hole 12 in the floor plate a, and then the above-mentioned. The drive motor 9 is driven to rotate the floor board a by 180 ° about the axis 15 of the horizontal rotary shaft 7 and position it under the floor board a as shown by P'in FIG. At this time, the floor board a is located above the other floor boards and smoothly rotates without interfering with the other floor boards.

After that, the fixing pin 14 is engaged with the fixing pin hole 12 by the hydraulic cylinder 13 to fix the floor board a, and in this state, the hydraulic cylinder 5 is operated to lower the floor pressure B to the original position. At the very least, the bottom surface of the floor board a forms a wide and smooth floor surface located on the surface. The present invention is applied to the inverted floor structure of various structures such as theaters and halls.

[0012]

[Effect of the device]

 According to the present invention, as described above, a floor plate having a chair fixed on the upper surface is rotatably supported around a horizontal axis on the floor approaching top equipped with a lifting drive mechanism, and the floor plate is rotated around the horizontal axis by a rotary drive device. By rotating the chair, it is possible to automatically clean up the chair from the floor surface to form a floor with a wide smooth surface.It is easy and quick to clean up the chair without human power. The work is performed smoothly without interference with other floor pressures when the floorboards are turned over, and no special storage space for chairs is required.

According to the invention of claim 2, the fixing pin hole is formed in the floor plate, and the fixing pin and the forward / backward drive device of the pin which are engageable / disengageable with the pin hole are provided near the floor. The floor plate rotatably supported around the horizontal axis can be firmly fixed to the floor except when it is turned over.
