Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a rotary stool for a vehicle, which is used by rotating the stool in the front-back and left-right directions. The present invention relates to a rotating stool slide mechanism that can be slid onto.

[Conventional technology]

2. Description of the Related Art Conventionally, a rotating stool has been used that turns a seat in a traveling direction of a train, an automobile, or the like (hereinafter, referred to as “vehicle or the like”) and can face a seat in a rear row, for example. Such a rotary stool is one in which an underframe for constituting the stool main body is configured on the pedestal via a rotation device.
It is designed so that the maximum seat spacing can be ensured within the range in which the radius of gyration does not interfere with other rotating stools and wall surfaces arranged in front and rear.

[Problems to be solved by the device]

However, in this type of rotating stool, the seat position is always fixed and the seat spacing is narrow, so even when the stool body is rotated and used, a sufficient seat is provided between the stool body of the opposite seat. When it is not possible to form a space for use and the seats are used with the seat facing toward the window as in recent event cars, ensure a sufficient space in front of the knee between the wall surface and the seat body. There is a problem that it cannot be performed, and there has been a demand for a proposal for a rotary stool that can be slid in the front-back direction when the stool main body is rotated and used. However, if the stool body is configured to slide when the rotary stool is oriented in any direction such as front-back or left-right, the radius of rotation of the stool body is increased, and other rotary stools, walls of vehicles, etc. Or interfere with
This causes a problem that the passage space cannot be secured.

The present invention was made in view of the above problems, and only when the seat body is rotated in a specific direction, the seat body is slid backward to use the space of the seat, that is, the space in front of the knees of the seated person. It is an object of the present invention to propose a slide mechanism of a rotary stool capable of widening the space.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a slide mechanism of a rotary seat according to the present invention rotatably mounts an underframe via a rotation device on a leg stand fixed to a floor surface of a vehicle or the like, and mounts on the underframe. In a rotary stool formed by mounting and fixing a stool body, a mounting plate on which the rotating device is mounted is slidably mounted on a slide rail configured on the pedestal side, and the mounting plate is mounted at a substantially central portion of the mounting plate. In addition to forming a key-shaped groove, a stopper hole is opened on the leg base at a position corresponding to the normal use position and the slide use position along the sliding direction of the mounting plate, and the stopper hole is moved up and down from the lower surface side of the underframe. A stopper shaft that penetrates the key-shaped groove and the stopper hole is provided at a position where the key-shaped groove and the stopper hole overlap, and the stopper shaft is inserted through the key-shaped groove only at the lower end of the stopper shaft when the seat body rotates in a predetermined direction. Key-shaped groove-shaped protrusion that can be moved upward Constitute, it is an gist that the mounting plate is configured to be able to stop fixed to the normal use position and a slide position of use on the isosceles.

Also, in the vicinity of the stopper hole on the slide use position side,
It is also possible to insert a protrusion of the stopper shaft to form a rotation stop that prevents the stopper shaft from rotating.

[Action]

Thus, according to the above configuration, when the stopper shaft penetrates the key-shaped groove formed in the mounting plate and the tip of the stopper shaft is fitted in the slide hole on the leg stand on the side of the normal use position, , The projection formed on the stopper shaft is blocked by the key groove to stop the stopper shaft from moving upward, so that the lower end of the stopper shaft cannot be removed from the stopper hole, and therefore the mounting plate can be slid. I can't. Also, when the seat body is rotated in a predetermined direction such as the window side at this position, the orientation of the protrusion formed at the lower end of the stopper shaft becomes the same as the orientation of the key groove, and the stopper shaft is raised in the mounting plate direction. Since the lower end of the mounting plate can be removed from the stopper hole, the mounting plate can be slid to the slide use position side. When the mounting plate is slid to the slide use position, the lower end of the stopper shaft, which is always urged downward, fits into the stopper hole on the slide use position side, and the mount plate can be fixed to the slide use position. Stop spinning.

Sliding on the rails 10, 10 are arranged and fixed on the lower surface of the mounting plate 9, and further mounted in the grooves 10a, 10a of the rails 10, 10. The retaining members 12, 12 ... Protruding from the plate 9 side
Are fitted together.

A circular through hole 13a is cut out in a predetermined direction (passage side in this embodiment) in the substantially central portion of the mounting plate 9 to form the key groove portion 1.
The key-shaped groove 13 formed with 3b is transparently provided, and the key-shaped groove 13 is formed.
First, the stopper shaft 14 which is formed on the lower surface side of the underframe 3 and rotates together with the underframe 3 is passed through. The lower end portion of the stopper shaft 14 protruding from the lower surface of the mounting plate 9 has a protrusion 1 such as a hexagon headed bolt that substantially matches the shape of the key groove portion 13b of the key groove 13.
5 is integrally formed, and the projection 15 has a key groove portion 13
The structure is such that the stopper shaft 14 can be allowed to escape upward only when the stopper shaft 14 is rotated to the b side. Further, the stopper shaft 14 connects one end of a relay member 17 such as a release or a connecting rod to a link 16 formed on the underframe 3 side, and the other end is provided at an appropriate position such as the front end portions of the sleeves 5 and 5. By connecting to the release lever 18 and operating the release lever 18, the stopper shaft 14 can be moved up and down. Further, an elastic member 19 such as a spring is connected to the tip 16a of the link 16 and always pulled downward to urge the stopper shaft 14 downward.

Further, stopper holes 20 and 20 for fixing the stool body 7 to the normal use position X and the slide use position Y are provided on the leg stand 1. The stopper holes 20 and 20 are respectively the stopper shaft 1
In this embodiment, stopper holes 20 and 20 are formed at both ends of the upper surface of a trapezoidal slide base 21, and the stopper hole 20 on the slide use position Y side is formed. Stopper shaft 14 near
The projection 15 formed at the lower end of the
A rotation stop 22 is configured to prevent the rotation of the seat 4 and thus stop the rotation of the seat body 7. The stoppers 24 formed on the lower surface of the mounting plate 9 come into contact with 23 and 23 along the sliding direction of the mounting plate 9 on the pedestal 1 so as to regulate the normal use position X and the slide use position Y of the mounting plate 9. It is a stopper receiver arranged and configured. The stopper receivers 23, 23 are formed with a distance Z corresponding to the sliding range of the mounting plate 9, and the mounting plate 9 slides within the distance Z range.

As shown in FIG. 5, in order to pull back the mounting plate 9 from the slide use position Y to the normal use position X, elastic members 25, 25 such as springs are provided between the proper position on the side of the pedestal 1 and the proper position of the attachment plate 9. It is also possible to intervene.

Next, a method of using the rotary seat slide mechanism according to the present invention will be described.

When the lower end of the stopper shaft 14 is fitted into the stopper hole 20 formed in the slide base 21 at the normal use position X, the seat body 7 can be rotated in a desired direction and used as a seat oriented in the desired direction. it can. At this time, when the stool body 7 is made to face a predetermined direction, for example, the window side B of the vehicle or the like, the projection 15 formed on the lower end portion of the stopper shaft 14 becomes a key-shaped groove 13 of the mounting plate 9 as shown in FIG. It matches the keyway 13b and can pass through it.
In order to disengage the stopper shaft 14 from below the mounting plate 9, the release lever 18 is operated to cause the lower end thereof to escape from the stopper hole 20, and the mounting plate 9 is moved backward against the biasing force of the elastic members 25, 25. Can be slid to. Thus, the stopper shaft 14 is stretched by the elastic member 19 at the slide use position Y of the mounting plate 9 and the lower end thereof is fitted into the stopper hole 20 to fix the attachment plate 9 in the slide use position and to project the protrusion. The stopper shaft 14 itself is prevented from rotating by fitting the stopper shaft 15 into the rotation stopper 22.

When the stool body 7 is returned from the slide use position Y to the normal use position X, the lower end of the stopper shaft 14 may be moved out of the stopper hole 20 on the slide use position Y side by operating the release lever 18. Then, the mounting plate 9
Is pulled by the elastic members 25, 25 and pulled back toward the normal use position X side, and the lower end of the stopper shaft 14 is fixed by being fitted into the stopper hole 20 at this position.

In addition, in the present embodiment, the stool body 7 is mounted on the window side B of a vehicle or the like.
An example is shown in which the stool body 7 is slid toward the passage side, that is, rearward so as to widen the space in front of the knees of the seated person when the seat body is rotated. Is not necessarily limited to the window side B to the passage side, but the design can be changed appropriately by changing the configuration direction of the rails 10, 10.

Further, the rotational operation portion of the seat body 7 is not limited to the above embodiment, and it may be configured to enable the rotational operation at the slide use position.

Further, it is possible to configure the seat use position of the seat body 7 in this embodiment to two or more.
