Description

[Detailed description of the invention]

[0001] The present invention relates to a footrest which is installed and used below a rear surface of a vehicle seat such as a train or a bus.

[0002]

2. Description of the Related Art Various types of footrests of this type have been developed and are currently being used, but a general form shown in FIG. 6 is known.

[0003] To explain a general footrest, an L-shaped footrest support rod 64 is provided at a predetermined interval on a frame 62 suspended below the back of the seat 60.

A foot plate 66 is provided between the support rods 64.
The footrest plate 66 is pivotally mounted at both ends by pins 68 in a free state and is configured to be rotatable.

[0005] The foot rest 66 is hung from the back of the seat 60 on the feet of the passenger (not shown) so that the foot rest 66 can be slightly inclined and supported by the pins 68 on both sides. Stopper 7 downward
0 is projected, and the stopper 70 allows the foot rest plate 6
6 is configured to be able to suppress excessive rotation.

[0006] Therefore, as shown in FIG. 6, the passenger puts his foot on the device and uses it in a slightly inclined state supported by the stopper 70.

On the other hand, when not in use, the foot rest plate 66 is rotated in the vertical direction with the pin 68 as a pivot, so that it is possible to avoid an obstacle to the feet of the passenger.

Therefore, in this type of footrest, the lodging control mechanism is provided on both sides of the footrest plate 66.
Problems such as increase in the number of parts, mounting of the foot control mechanism on the stopper welded to the frame 62, poor workability, and the provision of the control mechanism in the area where the foot is put, so that the passenger feels tight. was there.

When not in use, the footrest 66 is vertically supported, but in a free state, the vertical footrest 66 is restored in the horizontal direction by a relatively slight impact, and the foot may be obstructed. Also, there is a problem that the impact sound of the vehicle is propagated due to lack of certainty in the control mechanism for fixing and improperly.

[0010]

The problems to be solved are delusion of the footrest mechanism and generation of impact noise.

[0011]

[Means for Solving the Problem] The basic structure of this invention is as follows.

In a footrest mounted below the back of a vehicle seat such as a train or a bus, a support member for a footrest member rotatable via a support shaft is provided, and the footrest is spaced apart from the support shaft. On one side of the supporting member for a member, a footrest member is supported in a right angle direction, and on the other side of the supporting member for the footrest member, an arc-shaped curved outwardly toward the outer peripheral side of the axis of the support shaft. A pair of stopper portions provided with a guide portion are provided at a predetermined interval, and a stopper groove for controlling the footrest storage and a stopper groove for controlling the use of the footrest are provided on both sides of the guide portion of the pair of stopper portions at a predetermined interval. Are provided, and a support plate constituting a part of the footrest control mechanism is fixed to the outside of the stopper portion via the support shaft and is located beside the support shaft and far from the footrest member. One of the support plates The stopper groove for controlling the storage of the footrest and the stopper groove for controlling the use of the footrest are provided in the stopper portion, and the spring support shaft is fitted into the control groove and the stopper groove for controlling the storage of the footrest or the stopper groove for controlling the use of the footrest.

For replacement, maintenance and inspection of the footrest 10, the fixing by the screw 46 is released, and the support piece 38 is fixed. Can be removed simply by releasing it from the support hole 48, so that the operation can be performed easily.

Next, a method of using the present invention will be described. At the time of use, the passenger puts his foot on the foot rest member 16 and pushes it downward. Thus, with the spring 30 extended, the stopper portion 20 of the supporting member 18 for the foot rest member
8 rotates in the traveling direction of the clock hand with the support shaft. Therefore,
The spring support shaft 34 on the side of the foot control mechanism 52 is guided by the guide portion 21 and is fitted into one of the stopper grooves 23 of the stopper portion 20 provided at right angles and the control groove 26 provided on the support plate 24, The footrest member 16 is controlled to a posture in which the footrest member is lowered to the position of the passenger's feet, and does not become delusional (see FIG. 3).

At the time of non-use, the passenger jumps upward from below the footrest member 16. Thus, with the spring 30 extended, the stoichiometric portion 20 of the supporting member 18 for the footrest member rotates about the pin 28 in the direction opposite to the traveling direction of the clock hand. Therefore, the spring support shaft 34 on the footrest control mechanism 52 side is
1 and a stopper portion 20 provided in a right angle direction.
Is inserted into the other stopper groove 22 and the control groove 26 provided in the support plate 24, the foot rest member 16 jumps up from the position of the passenger's foot, is stored in the frame 12 below the rear surface of the seat 12, and is perturbed. (See FIG. 4).

[0030]

As described above, the footrest of the present invention is provided with a cam portion on a rotatable footrest support member, a guide portion, a footrest storage control stopper groove, and a footrest. Provision of a stopper groove for use control, for example, enables reliable control of use and non-use of the footrest. Therefore, it is possible to surely carry out the footrest delusion during use and non-use, and to prevent the generation of an impact sound due to the delusion that could not be avoided in the past. In addition, assembling of only the footrest mechanism becomes possible, workability is improved, and since there is no mechanical part where the footrest is put, the passenger's foot can enter the back.
