Title:
SPLIT RING LEVER CLAMPING ARRANGEMENT
Document Type and Number:
WIPO Patent Application WO/1993/009904
Kind Code:
A1
Abstract:
A portable electric router having a depth of cut adjustment mechainsm including an adjustment ring (26) which engages a screw thread on the motor housing (12) and rotationally engages the router base (20). The adjustment ring is formed as a split ring with radially directed projections (34, 36) adjacent opposite sides of the split. One of the projections (34) is formed with a camming surface (42) and a clamp lever (44) is provided with a camming surface (46) slidably engaging the projection camming surface. The projection with the camming surface is captured between the other projection and the clamp lever so that rotation of the clamp lever in a first direction forces the projections toward each other to clamp the adjustment ring to the motor housing and the base and rotation of the clamp lever in a second direction allows the projections to separate to release the adjustment ring.
