DETAILED DESCRIPTION

[0020] Referring to FIG. 1, an apparatus for providing a vehicular fender extension according to a first embodiment of the invention is shown generally at 10, located within a wheel-well 6 of a pickup truck 8. The apparatus 10 may be used to prevent road spray, such as, by way of non-limiting example, mud, rocks or sand, from hitting the side fenders of the truck 8.

[0021] Turning to FIG. 2, an exploded perspective view of the apparatus 10 is illustrated. The apparatus 10 comprises a fender extension 20 slideably supported by a guiderail 60 mounted within a wheel-well casing 90. The fender extension 20 may be moved between a first retracted position, as illustrated in FIG. 3, and a second extended position, as illustrated in FIG. 4, by a pair of linear actuators 80, as will be described below.

[0022] Referring to FIG. 2, the arcuate fender extension 20, includes a top surface 32 and extends between first and second ends, 22 and 24, respectively and between outside and inside edges, 26 and 28, respectively. The top surface 32 includes a plurality of linear tracks 30 thereon. The linear tracks 30 extend between the outside and inside edges, 26 and 28. As best seen in FIG. 5, each linear track 30 comprises a first and a second upright wall, 34 and 36, respectively, with first and second inward flanges, 38 and 40, respectively, forming a T-shaped slot 42 therebetween, the purpose of which will be set out further below. An upright wall 44 extends radially outwards from the top surface 32 at the outside edge 26. First and second mounting tabs, 46 and 48, respectively, extend axially therefrom the inside edge 28 of the fender extension 20 at locations corresponding to the linear actuators 80, as will be set out below. Each mounting tab, 46 and 48, includes a pair of mounting holes 50 radially therethrough.

[0023] The arcuate guiderail 60, includes top and bottom surfaces 72 and 74, respectively, and extends between first and second ends, 62 and 64, respectively, and between outside and inside edges, 66 and 68, respectively. A plurality of T-shaped guides 70 extend from the bottom surface 74. Each guide 70 extends between the outside and inside edges, 66 and 68, and is formed at a location corresponding to the linear tracks 30 on the fender extension 20. As best seen in FIG. 5, each guide 70 is sized to engage within a slot 42, such that each linear track 30 may slide thereon each corresponding guide 70.

[0024] The arcuate wheel-well casing 90, includes top and bottom surfaces 102 and 104, respectively, and extends between first and second ends, 92 and 94, respectively, and between outside and inside edges, 96 and 98, respectively. A pair of recessed cavities 100 are included within the top surface 102. Each recessed cavity 100 extends transversely between the outside and inside edges, 96 and 98, and is sized to receive a corresponding linear actuator 80 therein. Each linear actuator 80 extends between a stationary end 82 and a moveable end 84. Each recessed cavity 100 includes a mounting bracket 108 proximate to the inside edge 98. The stationary end 82 of each linear actuator 80 is secured to the corresponding mounting bracket 108 by any known means, such as, by way of non-limiting example, with a cross bolt and cross pin, as is commonly known. A pair of covers 122 may be secured to the top surface 102 of the wheel-well casing 90 to enclose the linear actuators 80 within the recessed cavities 100, and may be secured by any known means.

[0025] Referring to FIGS. 2 and 6, a bracket 86 is comprised of a top portion 87 and a base portion 88. The top portion 87 is mounted to the moveable end 84 of each linear actuator 80, by any means as is commonly known. A slot 110 extends through each recessed cavity 100 from the top surface 102 to the bottom surface 104 corresponding to the range of motion of the bracket 86 mounted to the moveable end 84 of the linear actuator 80. The bracket 86 extends through the slot 110 with the base portion 88 secured to the corresponding first or second mounting tab, 46 or 48, on the fender extension 20 by any known means, such as, by way of non-limiting example, screws, bolts or welding.

[0026] The wheel-well casing 90 includes a mounting flange 112 along the outside edge 96 extending radially inward from the top surface 102, between the first and second ends, 92 and 94. The mounting flange 112 includes bottom, outside and inside surfaces 114, 116 and 118, respectively. The top surface 72 of the guiderail 60 is secured to the bottom surface 114 of the mounting flange 112 by any known means, such as, by way of non-limiting example, screws, welding or adhesives, such that the second ends 64 and 94 are aligned. A plurality of mounting holes 120 extend therethrough the mounting flange 112, between the outside and inside surfaces, 116 and 118.

[0027] The apparatus 10 is installed while in the first retracted position as illustrated in FIG. 3. The apparatus 10 is positioned such that the wheel-well casing 90 is located within a wheel-well 6 with the mounting flange 112 aligned with the outside edge of the wheel-well 6 and it is mounted thereon by any known means, such as, by way of non-limiting example, screws, bolts or clamps. It will be appreciated that the illustrated embodiment of the invention may be installed on the left-side wheel-wells of a vehicle, and a mirror of the illustrated embodiment may be installed on the right-side wheel-wells. The linear actuators 80 are connected to a control system, as is commonly known. When the linear actuators 80 are activated, they simultaneously to move the fender extension 20, supported by the guiderail 60, transversely distal to the truck 8, to the second extended position, as illustrated in FIG. 4. The linear actuators 80 may then be activated again to retract the fender extension 20 back to the first retracted position, as desired.

[0028] While specific embodiments of the invention have been described and illustrated, such embodiments should be considered illustrative of the invention only and not as limiting the invention as construed in accordance with the accompanying claims.
