Car fender trim expander

Abstract

A car fender trim expander includes a fixing disk, a telescopic tube, a sliding member, a linkage assembly, a roller, and a position limiting device. Therein, the fixing disk is to be installed on a wheel axle and rotates together with the wheel axle. The telescopic tube has a first and a second end, while the first end is pivotally connected to the fixing disk. The sliding member is slidingly disposed on the periphery of the telescopic tube. The linkage assembly is disposed between the sliding member and the fixing disk. The roller is disposed on the second end of the telescopic tube for contacting the inner edge of the fender trim. The position limiting device is for adjusting the stretching and pivotal swinging of the telescopic tube. Thereby, the convenience and easiness for operation is achieved.

1 . A car fender trim expander, comprising:
 a fixing disk, installed on a wheel axle and rotates together with the wheel axle, wherein a pair of pivot boards are provided on one side of the fixing disk;   a telescopic tube, with a first end and a second end, while the first end is pivotally connected to the two pivot boards;   a sliding member, slidingly disposed on a periphery of the telescopic tube;   a linkage assembly, disposed between the sliding member and the two pivot boards;   a roller, disposed on the second end of the telescopic tube for contacting an inner edge of a car fender trim; and   a position limiting device, disposed between the telescopic tube and the sliding member, and capable of moving between a fixed position and an acting position, wherein stretching of the telescopic tube and movement of the sliding member are limited when the position limiting device is at the fixed position, and stretching of the telescopic tube and movement of the sliding member due to the pushing or pulling caused by an external force are allowed when the position limiting device is at the acting position, whereby the telescopic tube thus pivotally swings against the fixing disk.   
     
     
         2 . The expander of  claim 1 , wherein the telescopic tube comprises an external tube and an internal tube, with one end of the external tube pivotally connected to the two pivot boards, while the sliding member is disposed on a periphery of the external tube, and the roller is disposed on one end of the internal tube. 
     
     
         3 . The expander of  claim 2 , further comprising a rotating member rotatably disposed on the external tube, wherein the rotating member drives the sliding member to move along an axis defined by the external tube when the position limiting device is at the acting position, whereby the external tube pivotally swings against the fixing disk. 
     
     
         4 . The expander of  claim 3 , wherein a handle is transversely disposed on the rotating member. 
     
     
         5 . The expander of  claim 3 , wherein a threaded section is provided on the external tube for the rotating member to screw on, while the sliding member is disposed between the external tube and the rotating member, whereby the rotating member is capable of self-rotating against the sliding member. 
     
     
         6 . The expander of  claim 5 , wherein one end of the rotating member is provided with a flange, while the sliding member is present as a barrel shape with a ring groove to be coupled with the flange. 
     
     
         7 . The expander of  claim 1  or  claim 6 , wherein the sliding member is formed of a first casing and a second casing. 
     
     
         8 . The expander of  claim 2 , wherein the position limiting device comprises a knob and a screw member, while the external tube is provided with a first chute, and the internal tube is provided with a second chute, whereby the knob is inserted through the sliding member, the first chute, and the second chute, and further fastened with the screw member. 
     
     
         9 . The expander of  claim 8 , wherein the linkage assembly is pivotally connected to the sliding member, on an axis defined by the knob. 
     
     
         10 . The expander of  claim 8 , wherein two outer lateral sides of the second chute are provided with a plane, respectively. 
     
     
         11 . The expander of  claim 8 , wherein an axial length of the first chute is shorter than an axial length of the second chute. 
     
     
         12 . The expander of  claim 1 , wherein the linkage assembly comprises at least two linkages, while a connecting bar is transversely disposed on a pivotal junction of the two linkages and the two pivot boards. 
     
     
         13 . The expander of  claim 2 , wherein one end of the internal tube is provided with a fork part, and the roller is disposed on a carriage, while the carriage is provided with a combining part for being fixed to the fork part, and an adjusting member is inserted through the fork part and the combining part for adjusting a pivotal swing angle of the carriage against the fork part.
