Description

[Detailed Description of the Invention] The present invention relates to a bumper device for a small vehicle such as a tricycle.

This patent application first provided an automatic tricycle equipped with a motor and having one front wheel and two rear wheels. In such a vehicle,
If possible, it is preferable to provide a certain amount of storage space as a storage space, and the storage space needs to be provided within the small body of the vehicle, where installation space is limited, and only the storage space should be separate from other parts. However, it is disadvantageous in terms of space and the number of parts to be attached increases.

On the other hand, it is preferable for such a vehicle to have a bumper that can cushion the impact when the front or rear side of the vehicle body collides with an obstacle or the like.

The present invention was created in order to meet the above-mentioned demands, as well as to solve the bifurcation problem rationally.
The trunk compartment is provided at the front or rear of the vehicle body and can be opened and closed at the front or rear using a lower hinge part as a fulcrum, and an elastic body is provided that protrudes forward to cover the hinge part, which is used as a bumper, and hinge metal fittings are used. To provide a bumper device which improves the appearance by hiding the bumper, reduces impact and protects the vehicle body, and also allows the hinge fitting to serve as the bumper mounting fitting, thereby achieving common parts.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a side view of the tricycle, Figure 2 is a plan view of the same, and Figure 3 is a front view of the same. Although the example uses a tricycle, it can also be applied to motorcycles and motorized four-wheeled vehicles. It is something.

Briefly, a tricycle 1 includes a front body 2 and a rear body 3, a front wheel 4 serving as a single steering wheel is provided at the frontmost part of the front body 2, and a handle 5 is provided at the top. It is being A low floor type floor 6 is installed in the middle part, and a seat post 7 having a seat 8 on the upper part is installed above the rear part of the floor 6, and the rear body 3
A joint 9 is connected to the rear lower part so that it can swing up and down (swing movement), and the joint 9 connects to the front body 2.
slides left and right against the rear vehicle body 3 (rolling motion)
The rear vehicle body 3 is provided with two rear wheels 10 that are freely connected and serve as driving wheels.

Next, to explain the trunk provided with a bumper according to the present invention, a leg shield 11 is provided at the front part of the front vehicle body 2, and the leg shield 11 is provided with a fourth leg shield 11.
As shown in FIGS. 8 to 8.

The leg shield 11 is slightly larger in the left and right directions than the width of the passenger's body, and is provided from the bottom of the handlebar 5 to the top of the front wheel 4. In the embodiment, the lower part constitutes the front fender part 12, and the floor part 6 is behind this. It is formed to extend. At the top of the leg shield 11, a housing section 13 for headlights and blinker lights is formed with an open front.
4 and 14 are formed in a hanging manner. The portion below the storage portion 13 of the leg shield 11, between the left and right wall surfaces 14, and the portion surrounded by the front fender portion 12 is recessed to the back to form a storage recess 15, and a middle portion of the back wall 15a of the recess 15 is formed. A bracket 21 is provided on the frame 2a, and the intermediate back portion of the leg shield 11 is tied and supported to a head tube 2b provided at the front end of the frame 2a. A cover 16 having a recess 16a surrounding the head tube 2b in the middle is provided on the back of the leg shield 11, and the back of the cover 16 is closed with a lid plate 17. In the embodiment, the lower part of the cover 16 hangs down and extends rearward to form the flat upper surface 6a of the floor section 6, and the left and right wall surfaces 14,1
4, the left and right sides of the fender part 12 are extended rearward to form left and right side walls 6b of the floor part 6.

The concave part 15 opens vertically in front of the middle part of the leg shield 11, and a trunk lid 18 is provided so as to cover the opening edge 15b on the front side of the concave part 15. The trunk lid 18 can be opened and closed with a hinge fitting 19, and its lower end can be opened left and right in front of the fender part 12. It is pivoted at two points, and the lower end is a hinge that allows it to be opened and closed back and forth.
A protruding piece 18a is provided on the four circumferential inner surfaces of the opening 8, and a sealing rubber 20 is provided above and on the three left and right sides to seal the opening edge 15b in a closed state. The recessed portion 15 is bent inward from the lower end of the left and right wall surfaces 14, 14 and the lower front wall 13a of the upper storage portion 13, and is bent inward from the upper end of the fender portion 12 to form the upper and lower inner walls 15c of the recessed portion. , 15d, are formed integrally with other parts of the leg shield 11 so as to be connected to the left and right inner walls 15e and the back wall 15a connecting these inner walls, so this part has a concave box shape, and therefore the strength of the leg shield 11 is increased. can be achieved. The recess 15 is provided in front of the head tube 2b, and the back surface is covered with a cover 17 surrounding the head tube 2b, which is preferable in terms of appearance.
Furthermore, since the space in the middle part of the leg shield 11 in front of the head tube is used, it is advantageous in terms of space utilization.Furthermore, since the recessed part 15 is located in the middle part of the leg shield 11 in front of the head tube, and is provided above the fender part 12, it can be used in the floor part. This means that the front left and right sides of the 6 can be set forward and backward without increasing the overall length.

The hinge metal fitting 19 described above is enlarged in FIG. 9, and the front view is shown in FIG.
It consists of a member 19-1 and a bifurcated second member 19-2. The first member 19-1 is arranged vertically and is fixed to the lower left and right outer surfaces of the lid 18 with screws 19-3 and the like at the top and bottom, and has a loop portion 19-1a at the lower end. -2 is fixed to the upper right and left outer surfaces of the fender part 12 with screws 19-4, etc.
A loop portion 19-1a is inserted between the left and right raised pieces 19-2a, and is pivotally connected with a pin 19-5. In this way, the lower left and right sides of the lid 18 are pivotally attached to the fender portion 12. The first member 19-1 has a bent portion 19-1b at the rear, and protrusions 19-1 at the front left and right sides.
c, and an elastic body 22 such as rubber is attached to the outer surface of the first member 19-1. The rubber 22 is vertically long and thick, and the lower part is bent into a substantially L-shape on the side.
a extends to cover the front and side surfaces of the second member 19-2, and the upper part 22b extends over the first member 19-1.
It is formed so as to cover the entire outer surface of the. Upper part 2
2 is provided with a notch 22c on the bottom, into which the bent portion 19-1b described above is engaged, and the lower part 22a is provided with recessed portions 22d on the left and right sides, which are engaged with the protruding piece 19-1c. , the rubber 22 is fixed to the first member 19-1.

As a result, bumpers are provided on the left and right sides of the front lower part of the leg shield while covering the left and right hinge fittings 19.

In the above embodiments, the trunk is provided at the front, but the trunk may also be provided at the rear, and the mounting structure of the rubber 22 is not limited to the above, but may be attached in any desired manner.

As is clear from the above, according to the present invention, the hinge fittings of the trunk lid are provided on the left and right sides of the outer surface of the front or rear surface, and the outer surface of the hinge fittings is covered with rubber or the like.
Since this was used as a bumper, first of all, the hinge metal fittings were covered and had a good appearance.Also, since the hinge metal fittings were used as the mounting base for the bumper, there was no need for a mounting member for this, and the number of parts could be reduced. It has many advantages, such as the ability to provide the bumper in a location advantageous in terms of strength, such as the lid molded of synthetic resin or the like, and the metal fittings of the fender part.
