Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stage that can be stored upright.

[0002]

[Prior art]

 Traditionally, in kindergartens and Japanese restaurants, there is a stage that can be accommodated by folding it upside down or leaning it to the side in order to make effective use of the space. In many cases, the storage operation was troublesome when leaning against it, and the appearance of the storage state was poor in both cases.

[0003]

[Problems to be solved by the device]

 Therefore, the present invention provides a stage that can be easily stored upright with the stage surface facing the front side without bending, thus saving space and improving the appearance when stored.

[0004]

[Means for Solving the Problems]

 Therefore, in the present invention, the rear leg member and the front leg member having wheels are rotatably connected to the stage plate, and the wire winding drum is installed at the rear end to attach the wire to the rear leg member or the rear leg member. Pass it under the free roller provided at the lower position of the material, and connect its tip to the front leg material or the front leg mounting material, and project the guide rollers to the rear leg material or rear leg mounting material on both sides to the side. The rollers are housed and arranged in the vertical guide rails on both sides.

[0005]

[Action]

 At the time of storage, the wire is strongly stretched by rotating the take-up drum and pushes up the free roller, so that the rear leg material or the rear leg mounting material floats up and the stage plate can be tilted for the first time. The stage plate stands up because the material is pulled back. At this time, since the guide rollers projecting from the rear leg members or the rear leg mounting members on both sides slide while being guided by the vertical guide rails, the stage plate can be erected smoothly.

[0006]

【Example】

 Hereinafter, an illustrated embodiment of the present invention will be described. In this example shown in FIGS. 1 and 2, reference numeral 1 is a stage plate to which a mounting plate 12 is attached via joists 11, and a front leg mounting member in which a shaft 21 is coupled to the front ends of the mounting plates 12 on both sides. 2 is rotatably supported, and an axle 23 is mounted on the lower portion of both side flange portions 22 of the front leg mounting member 2 to provide a plurality of wheels 24 as a front leg member.

Further, a shaft 31 is mounted on the rear ends of the mounting plates 12 on both sides, and a plurality of rear leg members 3 mutually connected by a shape steel 32 are rotatably connected to the shaft 31. Shaped steel 32 is supported by a lower portion of a bracket 33 near the rear leg members 3 on both sides, and a free roller 34 is connected to the bracket 33 by a pin 35. Reference numeral 36 denotes a reinforcing rib, which is formed by connecting both side portions of the shape steel 25 attached to the lower portion of the front leg mounting member 2 and the rear leg members 3 on both sides. The front leg mounting member 2 and the rear leg member 3 are interlocked with each other. I am letting you.

Further, a pair of wire take-up drums 4 which are rotated by a motor (not shown) are installed on both sides at the rear end, and the wires 5 pass under the free rollers 34 while being in contact therewith. It is wound around the roller 26 inserted into the shaft 21, inverted, passed through the free roller 34 again, and wound around the winding drum 4.

Then, as shown in FIGS. 3 and 4, a vertical guide rail in which a guide roller 61 is provided on each of the rear leg members 3 on both sides to have a mounting member 6 protruding laterally and the roller 61 is arranged in a wall 7. It is housed and arranged in the rule 71. The mounting member 6 is formed by inserting a roller base plate 62 having a pair of guide rollers 61 projecting in the vertical direction into a bolt 65 projecting from one holding plate 63 and sandwiching it with the rear leg member 3 so as to sandwich the other holding plate 64 and a nut 66. The guide roller 61 is provided by being attached to the rear leg member 3 by screwing.

Next, the operation of this example will be described. First, when storing the stage from the used state, it is sufficient to drive the motor, and by rotating the winding drum 4 in the winding direction, the wire 5 is stretched between the roller 26 of the front leg attachment material 2. Therefore, as shown in FIG. 5, the rear roller 3 is slightly pushed up by pressing the free roller 34 upward and tilting it.

As the wheel 24 is continuously rolled up by the subsequent winding of the wire 5, the front leg mounting member 2 is drawn and the stage plate 1 is tilted and gradually stands up as shown in FIG. At this time, the guide rollers 61 of the rear leg members 3 on both sides are housed in the vertical guide rails 71 arranged in the wall 7, and the stage plate 1 moves, so that the stage plate 1 can be smoothly erected. The front leg mounting member 2 and the rear leg member 3 rotate about the shafts 21 and 31, respectively, and maintain their vertical states via the reinforcing ribs 36, and the wheels 24 are always in ground contact. A limit switch (not shown) detects the standing of the stage and stops driving the motor.

When the stage is used, the motor 5 is rotated backward to feed out the wire 5 and the stage plate 1 is pulled out forward in the initial operation. The wheels 24 roll forward to move the stage plate 1 horizontally. Will be installed in. Furthermore, by changing the position of the roller base plate 62 between the sandwiching plates 63 and 64, the protruding length of the guide roller 61 can be finely adjusted, and the guide roller 71 can be reliably accommodated in the guide rail 71.

As described above, according to this embodiment, the motor 5 is driven so that the wire 5 slightly lifts the rear end portion of the stage plate 1 via the rear leg member 3 to easily perform the initial tilting of the stage plate 1 and to guide the stage plate 1. By the guide of the roller 61, the rising can be smoothly performed. In addition, the stage plate 1 is exposed to the front so that the appearance is good, and it does not take up space because it is not folded and stored.

Although the present example is configured as described above, the present invention is not limited to this. For example, the configuration of the front leg material having wheels is not limited, and the shape of the rear leg material is also appropriate. Further, the connection configuration of the front leg material and the rear leg material is not limited. On a large stage, an intermediate leg may be rotatably interposed between the front leg and the rear leg. Further, the wire winding drum may be manually operated regardless of the configuration, the number of installations, and the means for driving the same.

The wire may be passed under the free roller provided at a lower position of the rear leg material or the rear leg attachment material, and the attachment portion and the attachment structure of the free roller are arbitrary. The tip of the wire may be connected to the front leg material or the front leg attachment material. The guide rollers may be attached not only to the rear leg materials on both sides but also to the rear leg mounting materials, and the number and mounting structure thereof are not limited. Further, the configuration of the guide rail that accommodates the guide roller is also arbitrary.

[0016]

[Effect of device]

 According to the present invention, the initial tilting operation of the stage plate can be facilitated by slightly lifting the rear end portion of the stage plate through the rear leg member by tensioning the wire, and the guide roller can be smoothly stored upright. The effect is large, and the stage plate is exposed on the front surface, resulting in a good appearance.
