JPS6010204Y2 - Device to prevent muddy water from entering the air cleaner of a vehicle - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a device for preventing muddy water from entering an air cleaner suitable for an engine-equipped vehicle for traveling on rough terrain, such as an off-road tricycle or a three-wheeled buggy.

This type of vehicle, especially a tricycle, has two left and right frame tubes 1a, lb connected to the steering head extending rearward, and a frame plate 1c at the rear between the left and right frame tubes 1a, lb.
Pass the frame tube 1a.

A seat 2 and a rear fender 3, which are integrally connected, are mounted on the frame plate 1c.

Conventionally, in this type of tricycle, the intake port 4a of the air cleaner 4 is opened at the lower side of the rear fender 3, and therefore muddy water or the like stirred up by the rear tire or the like is sucked in, often resulting in a decrease in the function of the air cleaner.

This proposal aims to prevent the above problems.

To explain the embodiment shown in the drawings, an opening window 3a is provided in the rear fender 3 to form a space S between the seat bottom plate 2a and the frame plate 1c, and an air cleaner 4 provided below the frame plate 1c is inhaled. Connect the opening 4a to the frame plate 1
c is airtightly attached via a seal member 5 to open into the space S, and the peripheral edge of the opening window 3a of the rear fender 3 is brought into contact with the frame plate 1c with the seal member 6 in between.

To attach the seat 2 and the frame tubes 1a, lb, a front elastic receiver 7 is provided at the front between the two frame tubes 1a, lb, a rear elastic receiver 8.8 is provided on the frame plate 1c, and the seat 2 is attached to the seat 2.
A hook 9 provided on the lower front surface of the seat 2 is engaged with the front elastic receiver 7, and a protrusion 10.10 provided on the rear portion of the seat 2 is inserted into a hole provided in the rear elastic receiver 8.8 and engaged.

In this case, the above-mentioned space S is formed by combining existing parts such as the seat bottom plate 2a, rear fender 3, frame plate 10, etc., each of which has its own function. No special parts are required, and since the space S is placed under the seat bottom plate 2a, it does not affect the cushioning function of the seat.

In addition, when the intake port 4a of the air cleaner 4 is airtightly connected to the space S, the intake port 4a needs to be supported by a strong member. Focusing on a certain thing, that frame board I
Since the air cleaner suction port 4a is attached to C, mutual airtightness is well maintained.

Also, the peripheral edge of the opening window 3a of the rear fender 3 is also attached to the frame plate I.
Since it is stacked on the upper surface of C, the airtightness of the periphery of the opening window 3a of the rear fender 3 is similarly maintained well.

In the illustrated example, the seat 2 and the rear fender 3 are connected at the center portion 3 of the rear fender 3, which straddles both frame tubes 1a and lb.
b and each part of the seat bottom plate 2a are brought into close contact with each other and fixed by appropriate means, and the rear part of the rear fender 3 of the seat 2 is attached to the frame tube 1.
a, floating from lb.

A space S is provided by forming the opening window 3a in the rear fender 3 at a portion where the seat 2 is suspended from the frame tubes 1a, lb.

As shown in FIG. 3, the rear fender seal member 6 is made of rubber or the like and has a substantially convex cross section, and in the case of a figure similar to the planar shape of the opening window 3a, has a quadrilateral shape, and is adhered to the upper surface of the frame plate 1c.

The air cleaner seal member 5 is a bushing made of rubber or the like as shown in FIG.

In this case, as described above, the intake port 4a of the air cleaner 4 is opened in the space S between the frame plate IC and the lower surface of the seat 2, and the periphery of the opening window 3a of the rear fender 3 is sealed with the seal member 6 on the lower surface. Therefore, outside air is sucked in through the gap between the upper surface of the rear fender of the space S1 and the seat, and muddy water splashed up by the rear wheels does not enter the intake port 4a.

In the figure, 11 is a tool box installed downward on the frame plate 1c, 12 is a tool storage bag, and 13 is a seat bottom plate 2a.
This figure shows the bag holder attached to the bag 12. Providing these as shown in the figure will prevent muddy water from splashing onto the tools inside the bag 12.

14 is a locking hook attached to the rear of seat 2, 15
is a lock lever 1 that engages with the locking stepped portion of this hook 14.
16 is a fuel tank, and 7a is a pedestal for supporting the front elastic holder 7, which is attached to the frames la and lb.
