Shifter assembly including bezel lock and release mechanism

Abstract

A shifter assembly including a base having top and bottom surfaces. The base has leg slots formed through the top surface. Additionally, at least one channel is formed on the top surface. A light box having top and bottom surfaces is disposed about the base. The light box includes downwardly extending legs that are received in the leg slots formed through the top surface of the base. The legs include ratchet teeth formed thereon. A plurality of springs are disposed about the legs and engage the top surface of the base and the bottom surface of the light box for biasing the light box from the base. At least one pair of bezel locks are received in the at least one channel formed on the top surface of the base. The bezel locks are adapted to engage the ratchet teeth formed on the legs. The light box may be adjusted in a single direction from a starting position to a final position.

         7 . The shifter assembly of  claim 4  wherein the top surfaces of the male and female lock members include raised ribs formed thereon for assembling the male and female lock members against the force of the biasing spring.  
     
     
         8 . The shifter assembly of  claim 4  wherein the bottom surface of the male and female lock members include location tabs formed thereon for mating with a corresponding feature formed in the channel formed on the top surface of the base.  
     
     
         9 . The shifter assembly of  claim 4  wherein the male lock member includes a laterally extending projection formed on the second end.  
     
     
         10 . The shifter assembly of  claim 9  wherein the female lock member includes a cavity formed in the second end for receiving the laterally extending projection of the male lock member.  
     
     
         11 . The shifter assembly of  claim 1  including a release member associated with the light box and base for initiating movement of the light box from the starting position to the final position.  
     
     
         12 . The shifter assembly of  claim 11  wherein the release member comprises an arcuate body having proximal and distal ends, the distal end having extending proximally therefrom two spaced legs separated from each other by an engagement slot.  
     
     
         13 . The shifter assembly of  claim 12  wherein the distal end includes hook projections extending downward for releasably engaging corresponding projections formed on the base.  
     
     
         14 . The shifter assembly of  claim 12  wherein the two spaced legs include a top surface having a raised ridge formed thereon.  
     
     
         15 . The shifter assembly of  claim 14  wherein the two spaced legs include a bottom surface having a tab formed thereon.  
     
     
         16 . The shifter assembly of  claim 15  wherein the light box includes a travel guide defined by a top L-shaped extension and spaced forward and rearward bottom ramp extensions and wherein the raised ridges formed on the top surface of the release member are entrained in the L-shaped extension and the bottom surface of the release member slides on the spaced forward and rearward bottom ramp extensions.  
     
     
         17 . The shifter assembly of  claim 16  wherein the tab formed on the bottom surface of the release member engages the rearward bottom ramp extension for maintaining the release member within the travel guide.  
     
     
         18 . The shifter assembly of  claim 1  wherein the downwardly extending legs of the light box include flexible tangs formed at the ends for holding the downwardly extending legs within the slots formed in the base.  
     
     
         19 . A shifter assembly comprising: 
 a base having top and bottom surfaces;    a shift lever coupled to the base;    a light box having top and bottom surfaces and disposed about the base, the light box including a lever slot formed through the top surface for receiving the shift lever and wherein the light box includes a travel guide defined by a top L-shaped extension and spaced forward and rearward bottom ramp extensions;    at least one spring disposed between the top surface of the base and the bottom surface of the light box for biasing the light box from the base; and    a release member disposed in the travel guide and releasably coupled to the base, the release member adapted to contact the shift lever to initiate movement of the light box from a starting position to a final position.
