Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rear fender of a vehicle such as a trailer having a detachable upper fender between a front fixed fender and a rear fixed fender of a trailer for connecting and pulling a semitrailer.

[0002]

[Prior art]

 As a conventional rear fender for a trailer, there is a fixed rear fender device in which front and rear ends of an upper fender are attached by fastening means such as bolts and nuts between upper ends of a front fixed rear fender and a rear fixed rear fender.

On the other hand, there is a detachable rear fender device in which the upper fender can be detachably attached by a hinge, and an example of the attachment / detachment mechanism on the front side of the detachable rear fender device is shown in FIG. 3 and FIG. As shown, the attachment / detachment mechanism on the rear side has the same structure.

This front attachment / detachment mechanism includes an upper hinge plate 3 formed by winding a plate material into a hinge hole 2 on the lower surface of the front (rear) end of the detachable upper fender 1, a front fixed rear fender 4 (a rear fixed rear fender). The lower hinge plate 6 having a hinge hole 5 formed by winding a plate material at a position different from that of the hinge hole 2 is provided on the upper surface of the upper end of FIG. It is fixed.

The hinge shaft 8 is inserted through the hinge holes 2 and 5 of the hinge plates 3 and 6, and the upper fender 1 is attached to the front fixed rear fender 4 (rear fixed rear fender).

In this detachable rear fender device, the hinge shaft 8 inserted into the hinge holes 2 and 5 of both hinge plates 3 and 6 comes out while the vehicle is running, and the upper fender 1 is fixed to the front rear fender 4 (rear Preventive means for preventing the fixed rear fender from coming off is provided, an example of which is shown in FIGS. 3 and 4, and another example is shown in FIG.

In FIGS. 3 and 4, the hinge shaft 8 has a bent portion (L-shaped tip portion) 8a bent at a right angle at the tip thereof and a U-shaped spring steel or the like. A clip 9 is formed by a central folded portion 9a and a recessed portion 9b sandwiched between the left and right ends, and the clip 9 is riveted to the front fixed rear fender 4 (rear fixed fender) and the bent portion 8a of the hinge shaft 8 is formed. The hinge shaft 8 is fastened by sandwiching it between the two.

In FIG. 5, the bolt 11 attached to the front fixed rear fender 4 (rear fixed rear fender) is inserted into the fixing hole 10a provided in the fixed plate 10 bent into an L shape, and the wing nut is attached. By fixing 12 to the bolt 11 and fixing the fixing plate 10, the fixing plate 10 prevents the outer end of the rear fender of the hinge shaft 8 from coming out.

A rear fender device for a trailer, in which an upper fender is provided between the front rear fender and the rear rear fender to cover a rear wheel of a trailer for connecting and pulling a semitrailer, is used as a rear fender device of the present applicant. There is known a mounting structure for a rear fender of a tractor disclosed in 63-32787 and a rear wheel fender for a tractor disclosed in Japanese Utility Model Laid-Open No. 2-123477.

[0010]

[Problems to be solved by the device]

 In the means for preventing the hinge shaft 8 from coming off by the clip 9 shown in FIGS. 3 and 4, since the clip 9 has to be formed of a steel material having extremely strong elasticity such as spring steel, the bending accuracy thereof can be obtained. It was difficult to be handled, and the material cost was high, and it was expensive.

Further, the means for preventing the hinge shaft 8 from coming off by the wing nut 12 shown in FIG. 5 often loses the wing nut 12 and the fixing plate 10 that are unscrewed when the upper feeder 1 is removed.

Further, when the upper rear fender 1 which is currently popular is fixedly attached to the front fixed rear fender 4 (rear fixed fender) and the fixed rear fender is converted into a detachable rear fender, There was also a problem that additional processing such as drilling was required to attach the means for preventing the hinge shaft 8 of the detachable rear fender from coming off.

The present invention solves the above-mentioned problems in the conventional vehicle rear fender, reduces the cost without increasing the number of parts, and ensures the fixing of the hinge shaft without additional processing. The purpose is to

[0014]

[Means for Solving the Problems]

 In the present invention, lower hinges are attached to the ends on the front fixed fender and the rear fixed fender, respectively, and upper hinges are attached to both ends under the upper fender, respectively, and the lower hinge of the front and rear fixed fenders and the upper hinge of the upper fender are hinged shafts. In a rear fender of a vehicle, which is engaged with the upper fender on the front and rear fixed fenders, a locking member for locking the L-shaped tip of the hinge shaft is extended to the lower hinge attached to the front and rear fixed fenders. It is characterized by having done.

[0015]

[Action]

 The rear fender of the vehicle of the present invention has a lower hinge extended by a locking member that locks the L-shaped tip of the hinge shaft without increasing the number of parts and without the need for additional processing of the front and rear fixed rear fenders. The shaft can be fixed securely.

[0016]

【Example】

 Next, an example of implementation of the present invention will be described below with reference to FIG. Also in this embodiment, an upper hinge plate 3 which is a hinge hole 2 formed by winding a plate material is attached to the lower surfaces of the front and rear ends of the detachable upper fender 1 by fastening means 7 such as bolts and nuts.

A lower hinge plate 15 is provided on the upper surface of the upper end of the front and rear fixed rear fenders 13 with a hinge hole portion 14 formed by winding a plate material at a different position from the hinge hole portion 2, and a lower hinge plate 15 is a bolt nut. It is fixed by fastening means 7 such as.

The hinge shaft 8 is inserted into the hinge holes 2 and 14 of the hinge plates 3 and 15 to fix the upper fender 1 to the front and rear fixed rear fenders 13. A bent portion (L-shaped tip portion) 8a is formed by bending the tip portion at a right angle, and these points are not different from the conventional one.

However, the lower hinge plate 15 has an upright portion 17 in which a specially shaped locking groove 16 is formed integrally with the bent portion 8a at a right angle to the bent groove 8a. It is composed of an introducing portion 16a for introducing 8a and a locking portion 15c for locking the bent portion 8a introduced by the protruding portion 16b.

Therefore, the hinge shaft 8 inserted into the hinge holes 2 and 14 of both hinge plates 3 and 15 and fixedly attached to both hinge plates 3 and 15 has the bent portion 8 a at the rising portion of the lower hinge plate 15. The bent portion 8a is locked by introducing from the introduction portion 16a of the locking groove 16 formed in 17 into the locking portion 16c, bypassing the protruding portion 16b.

Therefore, the hinge shaft 8 is pulled out from the hinge holes 2 and 14 by the locking of the bent portion 8a, and the front and rear fixed rear fenders 13 and the upper fender 1 are disconnected from each other by the hinge plates 3 and 15. To be prevented.

In another embodiment shown in FIG. 2, instead of the locking groove 16 for fixing the bent portion 8a of the hinge shaft 8 of the previous embodiment, a folding shaft slid in the withdrawing direction of the hinge shaft 8 is used. An enlarged locking curved portion 18 on the inner side, into which the curved portion 8a can be inserted and locked, is formed integrally with the lower hinge plate 15.

[0023]

[Effect of device]

 As described above, the present invention prevents the hinge shaft that fastens the hinge holes of the lower hinges attached to the front and rear fixed fenders and the hinge holes of the upper hinges attached to the upper fender from coming off. Therefore, an upright portion having a locking groove, which is a locking member for locking the L-shaped tip of the hinge shaft, or a locking curved portion is integrally provided on the lower hinge plate.

Therefore, unlike the conventional case, a separate component for fixing the L-shaped tip of the hinge shaft is not required separately, so that the number of components does not increase. In addition, it is no longer necessary to newly provide mounting holes for attaching the parts that fasten the L-shaped tips of the hinge shafts to the front and rear rear fenders. This is a useful idea that, in combination with not doing so, can securely fix the hinge shaft while reducing cost.
