Abstract: A vehicle convertible top is moved by hydraulic cylinders between extreme raised and lowered positions. The cylinder ends are connected to ports in a reversible hydraulic pump in one end of an elongated housing, which has a reservoir in the other end, separated by a pump cap. The pump cap houses two fluid circuits connecting the pump to the ends of the cylinders. Each circuit has an end of cycle hydraulic locking device comprising a normally-closed valve and a valve actuator. The circuit valves are alternately opened by pump pressure to pressurize one end of the cylinders to alternately raise and lower the top. The opened valve closes when the pump ceases operation, preventing fluid backflow through the one circuit to the pump. This hydraulically locks the top in extreme raised and lowered positions to facilitate top latching and tonneau installation.

Abstract: A latch mechanism for latching a convertible top header to a vehicle windshield header comprises a latch hook receiver mounted adjacent to each end of the windshield header and a pair of movable latch members each having a free end mounting a hook. A mounting bracket located adjacent to each end of the top header has an elongated base slot and an intersecting curvilinear branch slot adjacent to its outer end. A guide pin and a spaced drive pin are carried by each latch member. The guide pin is received within the base slot and the drive pin is received within the branch slot in the unlatched position. A drive link is connected to each latch member drive pin. Operation of the drive link pivots the latch members about the guide pins until the drive pins enter the base slots and terminally slide both pins toward the inner ends of the base slots to move the latch members from unlatched to latched positions.
Abstract: A vehicle convertible top has hydraulic cylinders for moving the top between extreme raised and lowered positions. The cylinders each have a pair of fluid translating ports each connected to ports in an elongated housing. A reversible hydraulic pump is in one end of the housing, while a reservoir is in the other end, separated by a pump cap. The pump cap houses two fluid circuits each connected to a housing port and each including an end of cycle hydraulic locking device which comprises a normally-closed valve and a valve actuator in each circuit. In one direction of pump operation, one of the valves is opened by pressure fluid in the one circuit to enable the outflow of the pressure fluid to the cylinders. The other valve is forced open by its actuator, in response to pressure in the one circuit, to enable the return flow of fluid to the pump through the other circuit. The one valve closes when the pump ceases operation, preventing fluid backflow through the one circuit to the pump.
