DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cargo loading device for a vehicle in which an engine is mounted at the rear between a pair of left and right front steering wheels.

(Prior technology) A four-wheeled vehicle with an engine mounted behind a pair of left and right front steering wheels, a steering handlebar diagonally above and rearward between the two front wheels, and a straddle-type driver seat behind the steering handlebar. etc. have traditionally existed. If a large cargo loading space is required for this type of vehicle, it may be possible to use the relatively large space between the two front wheels, but in this case, the engine located behind the A problem arises in that the wind becomes difficult to hit.

In addition, when the left and right fenders of both front wheels were integrated, there was a problem in that it became difficult to see from the driver's seat the vicinity of the ground contact points of both front wheels, making it difficult to drive, especially on rough or narrow roads.

(Objective of the Invention) The present invention was made in view of the above circumstances, and it is possible to secure a large cargo loading space without deteriorating the engine cooling performance, and even though the left and right fenders are integrated, there is no space near the front wheels. To provide a cargo loading device for a vehicle that can improve the visibility of the vehicle, is suitable for lowering the center of gravity, and can protect the front fender from obstacles.

(Structure of the Invention) According to the present invention, a pair of left and right steering front wheels and a pair of left and right rear wheels are equipped with wide low-pressure tires, an engine mounted at the rear between the two front wheels, and a steering wheel between the two front wheels. A steering handlebar arranged diagonally upward and rearward, a left and right integrated front fender that covers above both front wheels and above between both front wheels, and a straddle-type driver seat arranged behind the steering handlebar. In the vehicle, the front fender has a notch that opens forward between the front wheels, and a portion below the notch at a height near the upper edge of the front wheel is surrounded on three sides by the notch. A transparent luggage loading platform is provided so that its front end protrudes forward from a portion of the front fender that covers both front wheels, and a cooling air passage is formed between the luggage loading platform and both front wheels to guide running air to the engine. This is achieved by a vehicle cargo loading device characterized by the following.

(Example) Figures 1 and 2 are a perspective view and a front view of a four-wheel vehicle for traveling on rough terrain, which is an embodiment of the present invention, Figure 3 is a perspective view of the vehicle body frame, and Figure 4 is a front fender in the center. FIG. 5 is a cross-sectional side view of the front part of the vehicle body, FIG. 5 is a cross-sectional view taken along the line V-V, and FIG. 6 is a plan view of the handle stopper.

In these figures, numerals 10 and 10 are the steering front wheels, and 12
The drive rear wheels (only one shown) are equipped with wide, ultra-low-pressure tires. The vehicle body frame 14 has a front axle 1 that connects both front wheels 10, 10.
6. A pair of front tubes 18, 18 rising upward from here, a main tube 20 extending rearward from the upper end gathering portion of both front tubes, etc. are provided. A bracket plate 22 is fixed to the front surface of the gathering portion of the front tube 18 and the main tube 20. The steering shaft 26 to which the steering handlebar 24 is fixed has its upper end connected to this bracket plate 22 and its lower end connected to the front axle 1.
A handle stopper 30 is fixed to each of the steering shafts 26, which are rotatably supported by brackets 28 fixed to the handlebars 6 and 6. When the handlebar 24 is steered at its maximum, the stopper 30 stops the bracket plate 2.
2 and restricts its rotation (Fig. 6). Note that 32 is a bracket fixed between the rear surface of this bracket plate 22 and the upper surface of the main tube 20.

A substantially U-shaped king pin bracket 34 is fixed to both ends of the front axle 16, and a knuckle 36 is pivotally supported here by a king pin 38 (FIG. 5).
The front wheel axle 40 supporting the front wheel 10 is attached to the nutcle 36.
and the knuckle arm 42 are integrally formed. The nutcle arm 42 connects the tie rod 4 to a pitman arm 44 fixed to the lower part of the steering shaft 26.
They are connected by 6. At the time of maximum steering of the main wheels 10, the knuckle arm 42 comes into contact with the kingpin bracket 34 (see the imaginary line in FIG. 5).

Reference numeral 50 denotes a cargo loading platform, which, as shown in FIGS. 4 and 5, includes a substantially horizontal ladder-shaped loading section 52 and support legs 54. The rear end of the loading section 52 is fixed to the front tubes 18, 18, and the supporting foot section 54
The lower end of is fixed to the front axle 16. As shown in FIGS. 1 and 2, this loading section 52 has both front wheels 1
It is located between the front wheels 10, 10 at a height near the upper end of the front fender 60, and its front end protrudes further forward than the front edge of the front fender 60. The lower part of this loading section 52 is open to the front. That is, a cooling air passage 58 is formed between the loading portion 52 and the front wheels 10, 10, which guides running air to the engine 56 located at the rear between the front wheels 10, 10.

60 is a front fender. The other day Fuender 60
are formed into a pair of left and right parts, and the front central part is the loading part 5.
It is notched towards the front so as to surround 2 from three sides,
Tongue portions 62 (only one of which is shown) protruding downward near the left and right inner edges of this notch portion are fixed to arms 64, 64 that stand outward and upward from the loading portion 52.
Further, support arms 66 bent into a substantially gate shape are fixed to the front tubes 18, 18 by brackets 68, 68. The lower surface of the front fender 60 is fixed to the brackets 70, 70 and the lower end of the support arm 66. A rearward center portion of the front fender 60 is cut out toward the rear to avoid interference with the steering shaft 26 and the front tubes 18, 18. Therefore, the front fender 60 can be easily attached and detached from the front of the steering shaft 26.

In FIG. 1, 72 is a rear fender, and 74 is a driver's seat.

In this way, the loading portion 52 of the loading platform 50 is located at a height near the upper edge of both front wheels 10, 10, lower than the top surface of the front fender 60, and the front central portion of the front fender 60 is positioned so as to surround this loading portion 52. Since the notch is provided, a large cargo loading space can be secured above the loading section 52, and the lower part thereof can be opened widely toward the front, so that the traveling wind can be sufficiently guided to the engine 56. The left and right fenders 60 are integral, and cover the steering shaft 26 and the front of the front tube 18 at the rear of the notch. Therefore, the muddy water etc. splashed by the front wheels 10, 10 cannot fly toward the handlebar 24, allowing the front fender 60 to fully exhibit its mud protection function.

Furthermore, since the loading section 52 is made up of pipes joined in the shape of a ladder and can be seen from above, the driver can easily see the vicinity of the grounding point of the front wheels 10, 10 through the loading section 52 from near the steering handlebar 24. .

Furthermore, since the loading section 52 is located at a height near the upper edge of the front wheels 10, the tires do not hit the loading section 52 when the front wheels 10 are steered, making it possible to increase the area of the loading section 52 and making it possible to carry cargo. It is also possible to set the center of gravity at a relatively low position. Also, the loading section 52
Since the front end of the vehicle protrudes forward from the front edge of the front fender 60, it is also possible to protect the front fender 60 from obstacles while driving.

Furthermore, since the notch edge at the front center of the front fender 60 surrounds the loading part 52 from three sides at a higher position than the loading part 52, this notch edge has the function of preventing the cargo from falling off.

FIG. 7 is a side view of another embodiment, in which the loading platform 5
A guard member 76 is attached above 0A so as to surround the upper front and upper left and right sides of the loading section 52A. According to this embodiment, not only is it difficult for the cargo to fall in front of the loading section 52A, but also the cargo is prevented from directly hitting the left and right edges of the front notch of the front fender 60, so there is a risk that the cargo may damage the front fender 60. It also disappears.

(Effects of the Invention) As described above, the present invention forms a notch that opens forward and upward between both front wheels in a pair of left and right front fenders, and faces below this notch at a height near the upper edge of the front wheels. A transparent cargo loading platform was installed, and cooling air passages were formed between this and both front wheels. Therefore, it is possible to secure a large cargo loading space without sacrificing engine cooling performance.

Furthermore, since the loading platform between the front wheels is transparent, the driver can see the area around the front wheels through the loading platform, making it easier to drive on rough or narrow roads. Furthermore, since the loading platform is located at a height near the upper edge of the front wheel, the center of gravity when loaded is relatively low, and its front end protrudes forward beyond the part of the front fender that covers the front wheel, allowing the front fender to be kept clear of obstacles. It also has a protective effect. The left and right fenders are integrated, and the rear part of the notch repels muddy water splashed by the front wheels, so the front fender's mudguard function can be fully utilized.
