Abstract

VEHICLE FENDER ATTACHMENT AND SUPPORT STRUCTURE
Abstract of the Disclosure Structure for attachment and support of a fender of a vehicle such as a truck or the like in which the vehicle is subject to travel over rough or uneven terrain.
An attachment member extends freely through a bracket which is joined to the frame of the vehicle. The attach-ment member also extends freely through a portion of the fender which is adjacent the bracket. Thrust washers having convex and concave engagement surfaces freely encompass the attachment member and are positioned between the fender and the bracket and are attached thereto. Thus, relative movement between the fender and the bracket is permitted to prevent distortion or twisting of the fender as the vehicle travels over rough terrain.

Description

1~84~2 Back~round of the Invention A fender which covers the wheel of a vehicle, such as a truck, particularly a dual wheel or dual axle truck, must have considerable length and/or width, as the fender is supported by the frame or chassis of the truck. When the truck travels over rough terrain, the frame or chassis, even though relatively rigid, experiences twisting and/or bending and relative movement between portions thereof. Therefore, under such conditions, if the fender is rigidLy attached to the frame or chassis, the fender is subject to twisting and distortion, and damage to the fender and/or damage to the attachment means thereof results.

.

~19~4~2 Most known fender attachment devices have the objectionabLe feature that they secure the fender to the frame so rigidly that freedom of movement between the fender and the frame is so limited that damage to the fender occurs. Other known fender attachment devices permit excess freedom of movement between the frame and the fender, and damage to the fender occurs.
It is an object of this invention to provide structure for attachment of a fender to the frame or chassis of a vehicle, such as a truck or the like, by which controlled relative movement between the frame and the fender is permitted. Therefore, the fender and attachment means are protected against damage as the vehicle travels over rough terrain or irregular surfaces or the like and as relative movement in the form of twisting or distortion occurs between portions of the frame.
It is a further object of this invention to provide such attachment structure which permits freedom for relative movement between the frame and the fender while also firmly attaching the fender to the frame.
Other objects and advantages of this invention reside in the construction of parts, the combination thereof, the method of production, and the mode OL
operation, as will become more apparent from the following description.

Brief Descrintion of the Views of the Drawin~
.
FIG. 1 is a side view, with parts broken away, showing a truck having a fender over the rear wheels ~9~3462 thereof in which the fender is a~tached to the frame ofthe truck by the support and attachment structure of this invention.
FIG. 2 is an enlarged perspective view showing the fender of FIG. 1 and the fender support and attachment structure of this invention.
FIG. 3 is an exploded perspective view drawn on a larger scale than FIG. 2, showing a portion of the fender o~ FIGS. 1 and 2 and the means for attachment of the fender to the frame of the vehicle.
F-rG. 4 is a fragmentarj sectional view drawn on a larger scale than FIG. 3, showing a portion of the fender of FIGS. 1, 2, and 3 and the means of this invention for attachment of the fender to the frame of the vehicle.
FIG. 5 is a fragmentary sectional view, similar to FIG. 4 and drawn on the same scale as FIG. 4, showing the structure of FIG. 4 and illustrating the type of relative movement possible between the fender and frame of the vehicle.

Detailed Description of the Invention FIG. 1 shows portions of a truck 10 which has a frame 12 which supports a load carrying member 14. The frame 12 is supported by a pair of axles, not shown, and a plurality of wheels 16. A bracket 20, a bracket 22, and a bracket 24 are attached to the frame 12 adjacent the wheels 16. The brackets 20, 22, and 24 are adapted to support a fender 30 which covers the wheels 16. A
midportion of the fender 30 is secured to the bracket 22 _4_ by means of bolts 32. The end portions of the fender 30 are attached to the respecti~e brackets 20 and 24 by means now discussed with respect to the bracket 24.
The bracket 24 is provided with an opening 40 therethrough. Secured to the bracket 24 by means of a weld 42, and in alignment with the opening 40, is a thrust washer 50 provided with an opening 52 therethrough.
The thrust washer 50 has a flat surface in engagement with the bracket 24 and a concave surface 54 facing away ~ from the bracket 24.
The fender 30 has an opening 56 therethrough in alignment with the opening 40 in the bracket 24 and in alignment with the opening 52 of the thrust washer 50. Secured to the fender 30 by means of a weld 58 is a thrust washer 60 provided with an opening 62 therethrough in alignment with the opening 56 in the fender 30. The thrust washer 60 has a c~nvex surface 64 in engagement with the concave surfac~ of the thrust washer 50. Thus, the thrust washers 50 and 60 are in mutual engagement and positioned between the fender 30 and the bracket 24.
A bolt 70 having a head 72 extends through the opening 56 in the fender 30, through the opening 62 in the thrust washer 60, through the opening 52 in the thrust washer 50, and through the opening 40 in the bracket 24.
The bolt 70 also has a nut 74 attached thereto and shown in engagement with the bracket 24~ Encompassing the bolt 70 between the head 72 and the fender 30 are concave-convex spring washers 76 and 78, which have the convex portions thereof in engagement. Between the spring washer 0 78 and the head 72 of the bolt 70 is a flat washer 80.

1~9~g62 As illustrated in FIGS. 4 and 5, the opening 40 through the bracket 24, the opening 52 ~hrough the thrust washer S0, the opening 62 through the thrust washer 60, and the opening 56 through the ~ender 30 are all significantly greater than the transverse dimension of the bolt 70 which extends therethrough.

OPeration .

When the truck 10 travels over rough or uneven terrain there is a distortion and/or twisting of the frame 12. Therefore, forces are pre~ent in the frame 12 and in the fender 30 which urge relative movement between the ends of the fender 30 and the frame 12. Due to the fact that the brackets 20 and 24 are secured to the frame 12, the forces present urge relative movement between the brackets 20 and 24 and the ends of the fender 30. As relative movement between the brackets 20 and 24 and the ends of the fender 30 is urged, the structure of this invention permits such relative movement. There is sliding relative movement between the thrust washers 50 and 60, as illustrated in FIG. 5, permitting relative movément between the ends of the fender 30 and the brackets 20 and 24. The relative movement between the thrust washers 50 and 60 is permitted as the openings 40, 52, 62, and 56 are greater than the tran~verse dimension of the bolt 70 which extends therethrough. The relative movement between the thrust washers 50 and 60 is against the resilient forces of the spring washers 76 and 78.
Relative movement between the thrust washers 50 and 60 permits angular and/or lateral movement between the ~19~g6~

brackets 20 and 24 and the portions of the fender 30 joined thereto through the respective bolts 70. The relative movement between the ends of the fender 30 and the brackets 20 and 24 can be in any one or more of a multiplicity of directions. As illustrated by arrows 90, 9.2, and 94 in FIG. 5, there may be angular and/or lateral movement between the fender 30 and the bracket 24.
Thus, as a result of the relative movement permitted between the brackets 20 and 24 and the ends of the fender 30, there is no twisting and distortion of the fender 30 or of the brackets.20 and 24 as the véhicle 10 travels over rough or uneven terrain. Also, there are no shearing forces upon the bolt 70 as the vehicle 10 travels over rough or uneven terrain. After such r,elative movement between the brackets 20 and 24 occur~, as illustrated in FIG. 5, the spring washers 76 and 78 urge the thrust w,ashers 50 and 60 and the fender 30 to return to the normal positions thereof, as illustrated in FIG. 4.
Although the preferred embodiment of the fender attachment and support structure of this invention has been described, it will be unde~stood that within the purview of this invention various-changes may be made in the form, details, proportion and arrangement of parts, the combination thereof, and the mode of operation, which generally stated consist in structure within the scope of the appended claims.
