Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a structure of a chair installed and used in a game hall such as a pachinko hall.

[0002]

[Prior art]

 As is well known, a chair installed in a pachinko hall has a pillar fixed to a floor surface in front of a pachinko machine, and a backrest-integrated seat plate is rotatably supported on the pillar. The seat plate is biased by a spring so that it can be slid forward so that the passage can be used as much as possible.When not in use, the seat plate slides forward to widen the rear passage. I try to keep it.

[0003]

[Problems to be solved by the device]

 In this way, the chair for the pachinko parlor was designed to be rotatable and slidable forward and backward, so it does not have a so-called reclining function, and there is a problem that it is easy to feel fatigue when sitting for a long time. It was However, there is a problem that the conventional reclining mechanism cannot be applied to this type of chair that can slide back and forth as it is.

[0004]

[Means for Solving the Problems]

 The chair of the present invention is intended to solve the above-mentioned problems. A support is provided at the upper end of a support, a support plate is provided on the support so as to be slidable forward and backward, and the support is provided between the support and the support plate. A tension spring for urging the receiving plate forward is stretched, and the front edge of the mounting plate is pivotally supported on a horizontal support shaft provided at the front portion of the receiving plate to connect the receiving plate and the mounting plate. A backrest-integrated seat plate fixedly mounted on the mounting plate is elastically tiltably supported rearward by interposing a compression spring therebetween, and further, a receiving plate slides rearward on the support body. In this case, an elastic tongue is provided which can lightly lock the receiving plate in the rearward sliding state against the elasticity of the tension bar.

[0005]

[Action]

 The seat plate is lightly locked in the backward sliding state, and in that state the seat plate can be tilted rearward to take a reclining posture, which is easy to use.

[0006]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a cylindrical column that is perpendicular to the floor surface. A rotatable mounting shaft 2 projects from the upper end of the column 1, and an upper end 3 of the mounting shaft 2 is formed into a bifurcated shape. A support 4 is fixed to the upper end portion 3.

The support 4 is in the shape of a rectangular tube, and shoes 5, 5 made of synthetic resin having a low friction coefficient such as Delrin are provided on both upper edges of the support 4. Reference numeral 6 denotes a receiving plate having groove-shaped rail portions 7, 7 formed on both side edges of the lower surface so that the shoes 5, 5 can slide. Further, as for 8, 8, one end is hooked on the rear edge of the lower surface of the receiving plate 6, and the other end is passed through the inside of the supporting body 4 and locked to the front edge of the supporting body 4, thereby A coil-shaped tension spring stretched between the support body 4 and the elastic force of the tension springs 8 and 8 urges the receiving plate 6 forward.

Bearing pieces 9 and 9 are integrally formed in an upwardly bent state on both side edges of the front part of the receiving plate 6, and the support piece 10 is horizontally supported by the bearing pieces 9 and 9. Then, bearing pieces 12, 12 are integrally formed in a bent downward shape on both side edges of the front part of the mounting plate 11, and the support shaft 10 is inserted through the bearing pieces 12, 12. A head 13 and a nut 14 are provided at both ends of the support shaft 10 to prevent the shaft from coming off. A coil-shaped compression spring 15 is interposed between the receiving plate 6 and the mounting plate 11, and a columnar elastic rubber 16 is interposed inside the compression spring 15. Reference numeral 25 denotes a pin fixedly planted on the upper surface of the receiving plate 6 so that the elastic rubber 16 is positioned by inserting the pin 25 into the elastic rubber 16.

A seat plate 17 is fixed to the mounting plate 11 with screws 18. A backrest 19 is integrally provided on the seat plate 17 via a connecting rod 20. Therefore, the backrest-integrated seat plate 17 is supported by the elasticity of the compression spring 15 and the elastic rubber 16 so as to be elastically tiltable rearward.

Reference numeral 21 is an elastic tongue provided in the support 4 so as to extend forward, 22 is a locking piece fixed to the lower surface of the front portion of the receiving plate 6 by welding, and the tip of the elastic tongue 21 is fixed. A circular arc-shaped locking portion 23 is formed in this, and the locking portion 23 faces the locking piece 22.

Therefore, when this chair is not used, the seat plate 17 is pulled forward and slid by the elasticity of the tension springs 8 and 8 as shown in FIG. 1, so that the rear passage space is kept wide. be able to. Then, when a user such as a pachinko player sits on the seat plate 17 and pushes the seat plate 17 rearward, the seat plate 17 slides backward and the locking pieces 22 are elastic tongue pieces as shown in FIG. By fitting into the locking portion 23 of 21, the seat plate 17 can be kept in the rearward sliding state against the elasticity of the tension springs 8, 8. When the user further pushes the backrest 19 with his / her back, the backrest-integrated seat plate 17 tilts rearward against the elasticity of the compression spring 15 and the elastic rubber 16 to be in a reclining state. At this time, since the elastic tongue piece 21 of the seat plate 17 is lightly locked to the locking piece 22, the seat plate 17 does not slide forward and return even if the foot is lifted off the floor surface. You can take a different posture and relax.

It should be noted that the elastic rubber 16 is designed such that the elastic rubber 16 is also compressed and exerts its elasticity while the compression spring 15 is being compressed by the tilting movement of the seat plate 17. The elastic force of the rubber 16 is also provided to assist the elastic force of the compression spring 15.

Since the locking piece 22 is lightly locked to the locking portion 23 to the extent that it can withstand the elasticity of the tension springs 8 and 8, it is affected by a slight forward force acting on the seat plate 17. The stopper 23 is easily separated from the elastic tongue 21 and the seat plate 17 slides forward and returns to its original state.

[0014]

[Effect of device]

 As described above, in the chair of the present invention, the seat plate is lightly locked by the elastic tongue in the backward sliding state, and in this state, the seat plate is tilted backward by pushing the backrest in the reclining state. It has the advantages of being able to relax and being able to reduce fatigue when sitting for a long time, and also to slide forward to maintain a wide rear space when not in use.
