Armrest structure of the back-seat of the heavy-duty motorcycle

Abstract

The invention relates to an armrest structure of the back-seat of the heavy-duty motorcycle; wherein, the structure is composed of a linking-sleeve and a handle set at both sides of the fix-base. One rectangular-and-hollow adjusting trough is respectively set at each side of the arc-shaped fix-base to facilitate bolts to be fixed around the cover of the oil box after penetrating; a penetrating-hole is respectively set at the outmost end of both sides to be slipped through by bolt for bolt's integrating with the bottom of linking-sleeve after slipping through; an open-cutting trough and a bolting-hole being reserved around the on-slipping hole, after the upper end of the linking-sleeve contacting with the on-slipping hole set at one end of the handle, the linking-sleeve and the handle will be integrated as one unit via the bolt's bolting force and the fortifying contact force of the open-cutting trough.

1 . The invention relates to an armrest structure of the back-seat of the heavy-duty motorcycle; the armrest structure is composed of one piece of arc-shaped fix-base, two pieces of linking-sleeve and two pieces of handle, respectively described as follows:
 one fix-base is arc-shaped and one rectangular-and-hollow adjusting trough is respectively set at each side of the arc-shaped fix-base to cooperate with bolts originally assembled around cover of the oil box of the motorcycle body to fix and position components after slipping through; a penetrating-hole  12  is respectively set at the outmost end of both sides to be slipped through by bolt for bolt's integrating with the bottom of linking-sleeve after slipping through;   two linking-sleeves are made to two stages with different diameters;   two handles respectively have one on-slipping hole at one end; moreover, one open-cutting trough and a bolting-hole are set around the on-slipping hole; slip handle on the upper end of linking-sleeve via on-slipping hole; then, bolt is bolted into the threaded hole, and the contact force is fortified by open-cutting trough around on-slipping hole to position and closely combine linking-sleeve with handle as an integrated unit;   therefore, the fix-base is assembled on the position of the bolts around the cover of the oil box of the motorcycle and the integrated linking-sleeve is vertically risen and being positioned and assembled with handle; hence, the back-seat rider can hold the handles instead of surrounding the body of the front-seat rider with hands to limit his operating the motorcycle; consequently, the effect on freeing the front-seat rider's operating the motorcycle and easing the back-seat rider's holding the handles will be achieved.   
   
   
       2 . An armrest structure of the back-seat of the heavy-duty motorcycle as claimed in  claim 1 , wherein said spacers can be set between the fix-base and linking-sleeve to rise the level of the handles for matching the various heights of the back-seat riders. 
   
   
       3 . An armrest structure of the back-seat of the heavy-duty motorcycle as claimed in  claim 1 , wherein said the handle is arc-shaped and can be horizontally adjusted its angle for matching the need of the user to achieve the effect of diversified application.
