Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention is a footrest for a saddle type rear two-wheeled vehicle with one or two steerable front wheels and a pair of left and right rear wheels. Relating to attachment devices.

(Prior Art) For example, a straddle-type rear two-wheeled vehicle such as a vehicle for traveling on rough terrain is supported by a steerable front wheel and a pair of left and right rear wheels, and the rider rides on a straddle-type seat arranged at the top of the frame. The vehicle is designed to be driven by riding on it, steering the front wheels using a stick handle, and making full use of the on-board engine. In this case, the rider stabilizes his/her riding position by placing his/her feet on a footrest placed at the center of the lower part of the frame. On the other hand, there are various suspension systems for the rear wheels of this type of vehicle, but there is one in which the rear wheels of this type of vehicle are suspended so as to be swingable up and down using a trailing arm (swing arm). When this trailing arm method is adopted, a support member for pivoting the tip end of the arm is arranged at the lower part of the frame. As for the trailing arm, it is desirable to limit the swing angle to a small value and to increase the amount of vertical swing of the rear wheel, which results in the trailing arm becoming longer and the supporting member moving forward accordingly. Therefore, the trailing arm support member and the footrest are close to each other,
A problem arises in that the space between the two is cramped, making it difficult to secure space around the rider's legs.

(Problems to be solved by the invention) As mentioned above, in the conventional straddle type rear two-wheel vehicle,
If a trailing arm is used for rear wheel suspension,
In view of the problem that the support member and the footrest are close together, making it difficult to secure space around the rider's foot, this idea integrates and organizes the configuration of the footrest and trailing arm support to secure space around the rider's foot. Saddle type rear 2 for the purpose of
A footrest attachment device for a wheeled vehicle is provided.

[Structure of the idea]

(Means for Solving the Problems) In order to achieve the above object, in the footrest attachment device for a saddle type rear two-wheeled vehicle of this invention, trailing arms for rear wheel suspension are extended outwardly from both ends of the frame. A cantilever-shaped bracket supporting the frame is protruded, and a horizontal L-shaped reinforcing bridge is connected between the front side edge of the frame and the front edge of the outer end of the bracket, and a footrest is mounted on this reinforcing bridge. Adopts a configuration with .

(Function) By adopting the above configuration, the bracket for supporting the trailing arm becomes compact with a cantilever shape, and since the reinforcing bridge is arranged horizontally, it can be placed close to the footrest. Since it does not interfere with the movement of the suspension, the trailing arm can be set longer.
On the other hand, since the footrest is also arranged on the reinforcing bridge, rigidity can be easily obtained with a simple structure.

(Example) The figures showing the example of this invention will be explained below.

The figure shows a straddle-type four-wheeled vehicle, which is supported by left and right front wheels 1 and left and right rear wheels 2 that are steered by a bar handle 4, and has a straddle-type seat 3 disposed above. The engine 5 is mounted in the center and drives the rear wheels 2 to drive the vehicle.

The lower frame 6 has a relatively narrow width and is arranged long in the front and rear, and on both sides of the front part thereof, a wisdombone type arm 7 is pivotally supported to suspend the front wheel 1. At the rear of the center of the frame 6, a cantilever-shaped bracket 8 is welded and fixed to both side edges of the frame 6 and protrudes outward. support The rear wheel 2 is suspended on the rear end of the trailing arm 9 so as to be able to swing up and down. A reinforcing bridge 11 is extended between the side edge of the frame 6 in front of the welded portion of the bracket 8 and the front edge of the outer side of the bracket 8 and is welded and fixed.
The reinforcing bridge 11 is formed in a horizontal L-shape, and a footrest 12 projecting outwardly is mounted on its front edge.

Therefore, the reinforcing bridge 11 is connected to the bracket 8.
The footrest 12 has a simple structure of sheet metal bent into a U-shape and has sufficient rigidity, and the bracket 8 has a compact cantilevered shape. can. The reinforcing bridge 11 is laid out in the horizontal direction, and there is nothing protruding upward before and after the footrest 12, so it does not interfere with the movement of the rider's feet. Sufficient ground clearance can also be secured. At the same time, the trailing arm 9 can be set longer, the swing angle can be reduced, and the vertical stroke of the rear wheel 2 can be increased.

[Effect of idea]

As described above, the footrest attachment device for a straddle-type rear two-wheeled vehicle according to this invention has a horizontal support bracket in front of the cantilever-shaped support bracket of the trailing arm for rear wheel suspension that protrudes outward from the frame. An L-shaped reinforcing bridge is provided with a footrest mounted on top of it, allowing space around the rider's legs to be secured even when the trailing arm is lengthened, and both the footrest and bracket have a simple structure that provides sufficient rigidity. This has the effect of improving functionality and reducing costs.
