Abstract
Abstract A device is provided for locking the top of a motor vehicle to the windshield frame of the vehicle. The device comprises a locking member arranged at a forward frame section of the top, a mounting provided at the windshield frame, as well as centering members effective between the top and the windshield frame. The locking member comprises a crank connected with an operating unit, this crank being equipped with a locking pin. The locking pin cooperates with a slotted guide track constituting the mounting, in such a manner that the movement of the locking pin within the track of the slotted guide track means results in a reciprocating motion of the frame section of the top. The device is capable of being advantageously employed in a convertible top vehicle.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
150 words
A locking device for a vehicle top having a forward frame section exhibiting locking means reversibly engagable with mounting means provided at a front windshield frame, said locking means comprising crank means, locking pin means attached to said crank means, and operating unit means for moving said crank means, and said mounting means comprising slotted guide means exhibiting a guide track slot for receiving said locking pin means, wherein rotation of said crank means from an unlocked to a locked position causes said locking pin means to enter and interact within said guide track slot to pull said vehicle top in a vertically downward direction, and wherein rotation of said crank means from said locked to said unlocked position causes said locking pin means to interact within said guide track slot to push said vehicle top in a vertically upward direction and to subsequently disengage from said guide track slot.
Claim 2
Dependent Claim
150 words
