Lift for vehicle hoods and the like
First Claim
1. A lift for raising and lowering a hood of a vehicle comprising:
- (a) an actuator having an axially extending housing having opposite ends;
(b) a pair of thrust rods in said housing oppositely reciprocal between a retracted position and an extended position, said rods adjacent one another in a side-by-side relationship in the retracted position one rod having an outer end pivotally attachable to said vehicle at a first location and the other thrust rod pivotally attachable to said hood at a second pivot location; and
(c) drive means for oppositely reciprocating said thrust rods to extend said rods from opposite ends of said housing to achieve a fully extended length approaching the combined length of the rods and housing.

Abstract
A lift for opening and closing truck hoods. The lift has a primary actuator with a pair of upper and lower thrust rods oppositely reciprocal within a housing driven by a reversible motor and chain. The rods are connected to the firewall and hood at pivotal connections. The connection on the hood may be slidable to provide clearance of obstacles such as engine compartment components. In an alternate embodiment, the upper thrust rod is pivotally connected to the interior of the hood and the distal end of the lower rod is pivotally attached to a second actuator which, when operated, will move the pivot point forwardly to achieve full or additional opening clearance of the hood. The actuator has a wide variety of applications where extended “reach” is desired.

8. A lift for raising and lowering the hood of a vehicle comprising:
-
(a) an actuator having a generally rectangular housing having opposite ends;
(b) a generally rectangular guide tube in said housing;
(c) generally rectangular thrust rods in said guide tube arranged in side-by-side relationship, said thrust rods having a retracted position and an extended position in which the thrust rods extend from the opposite ends of the housing; and
(d) drive means for reciprocating said thrust rods including a motor driving a sprocket, an endless chain extending in said housing driven by said motor and sprocket and connector means connecting said thrust rods to selected locations along said chain to oppositely reciprocate said rods.
