Description

[Detailed description of the invention] In route buses, etc., it is desirable to reduce the number of seats and increase the number of standing seats during rush hours, and increase the number of seats during other times.

The present invention aims to provide a simple structure for seats whose number can be adjusted by attaching and detaching them. Drill a hole and a bolt hole through which the bolt has passed, fix one side of the seat frame of the secondary seat to the outer end of the support rod and the outer end of the bolt, and screw a nut to the inner end of the bolt so that the upper end The folding leg is pivotally connected to the lower part of the other side of the seat frame of the secondary seat by a pivot point, and the lower end thereof is brought into contact with the floor surface.

The configuration of the present invention will be explained below with reference to drawings of embodiments of the present invention.

First, we will explain the correspondence between the symbols on the drawing and the names of the parts. 1 is the floor surface, 2 is the seat frame of the main seat, 3 is the support rod, 4 is the receiving hole, 5 is the bolt, 6 is the bolt hole,
7 is the seat frame of the secondary seat, 8 is Natsuto, 9 is the pivot point, 1
0 is a folding leg.

A receiving hole 4 through which a support rod 3 is passed is bored on one side of a seat frame 2 of a main seat fixed to a floor surface 1, and a bolt hole 6 through which a bolt 5 is passed is bored.

In the figure, both the support rod 3 and the bolt 5 are provided on the right side of the seat frame 2 in the left-right direction. Although the number of support rods 3 and bolts 5 is two each in the figure, it is not limited to two. Receiving hole 4 and bolt hole 6
The number of support rods 3 and the number of bolts 5 are also determined appropriately. In the figure, two receiving holes 4 are provided for one support rod 3, but the number is not limited to two depending on the structure of the seat frame 2.

One side of the seat frame 7 of the secondary seat is fixed to the outer end of the support rod 3 and the outer end of the bolt 5, and a nut 8 is screwed to the inner end of the bolt 5. In the figure, the left side of the seat frame 7 is fixed. The bolt 5 is tightened and fixed to the seat frame 2 by the nut 8.

A folding leg 10 is provided whose upper end is pivotally connected to the lower part of the other side of the seat frame 7 of the secondary seat by a pivot point 9, and whose lower end is brought into contact with the floor surface 1. In the figure, one folding leg 10 is shown at the lower right side of the seat frame 7, but the number is not limited to one, and two may be used.

Although the figure only shows seat supports and backrests for both the main seat and the secondary seat, armrests may also be provided.

The lower end of the folding leg 10 is not fixed to the floor surface 1.

Since the present invention has such a configuration, its functions and effects are as follows.

FIG. 1 shows a state in which an auxiliary seat is combined with a main seat, that is, a state in which the seat becomes a two-person seat. In this state, the secondary seat is supported on the floor 1 by the folding leg 10 on the right side, and the support rod 3 on the left side.
Since it is supported by the main seat supported on the floor surface 1 by four legs by the bolts 5 and 5, it can sufficiently withstand the load applied to the seat support.

Also, the secondary seat is made up of bolt 5 and nut 8.
It is firmly fixed to the main seat. Therefore, the secondary seat is stable without being thrown up or falling off due to vibrations of a vehicle such as a bus.

To remove the secondary seat from the main seat, remove the nut 8 and move the secondary seat outward, to the right in the figure, by applying force. If you remove the secondary seat, folding legs 1
0 around the pivot point 9 and folded under the seat frame 7, making it into the state shown in Fig. 2. Store it in an appropriate location in this condition.

To attach the secondary seat, pass the support rod 3 and bolt 5 through the receiving hole 4 and bolt hole 6, respectively, tighten the nut 8, rotate the folding leg 10 around the pivot point 9, and tighten the lower end. may be brought into contact with the floor surface 1.

11 is a front leg on one side of the main seat, and 12 is a rear leg.

During rush hour, the secondary seats can be removed to create more standing space and increase the capacity of buses, etc.

The secondary seat can be attached and detached by attaching and detaching the nut 8, so it is extremely easy to attach and detach the secondary seat. In route buses, it is necessary to attach and detach secondary seats during short periods of time between operations, so the ease of attachment and detachment in the present invention is an important practical advantage. It is necessary to adjust the distance between the secondary seat and the main seat depending on its intended use, such as whether it is for adults or children.
Since this uses the nut 8 and the nut 8, there is an advantage that the distance between the main seat and the auxiliary seat can be adjusted by adjusting the position of the nut 8.

In this way, according to the present invention, a removable seat for a route bus or the like can be obtained which is extremely easy to install and remove, and is of great practical value.

[Brief explanation of the drawing]
