Telescopic spring unit for car boot and hatchback flaps - has compressive force when extended to tilt locking unit automatically into stop position.

The first telescopic part (26) is attached to a base unit of the structure by a first connector (28). A second connector (24) for the second telescopic part (30) is connected to the locking unit (22). The tilt joint (32) and second connector conform with each other so that in the extended state of the telescopic spring unit (10) the compressive force derived from the gravity of the swivel unit passes through the two connecting points (24,28) to exert the tilting movement on the locking unit. The tilt joint can have at least a first movable force engagement point (K1) for transferring the force between one telescopic part and the locking unit. USE/ADVANTAGE - Fewer structural parts for easier economical prodn. and assembly of telescopic spring unit for car boot and hatchback flaps.

Operating swinging doors; checks. - An aircheck cylinder j pivoted to a plate c on the door frame has its piston-rod pivoted to a short arm e, which is pivoted at one end to the plate c and at the other end to an arm h pivoted to the door. A doorclosing spring n is connected at one end to a lug on the cylinder j, and at the other end by a link p to the arm e at a point between the connexion of the piston-rod and the pivot f, so that, as the door is opened, the spring is extended. A lug w on the arm e limits the opening of the door. An adjustable valve r in the check cylinder controls an air-escape aperture, by which the strength of the check can be varied. By completely closing the aperture, the door may be held in a slightly-open position until natural leakage allows it to close.

Piston-cylinder locking means

A positioning element to position two objects which are movable in relation to one another includes a cylinder in which there is an axially movable piston rod with a piston. The piston sealingly divides the cylinder into two working chambers by a piston ring, each of the working chambers containing blocking medium. The sealing by the piston ring can be bypassed during an insertion stroke of the piston rod. The piston includes a piston base body and a valve element, the valve element being movable along the base body to open and close a flow connection between the working chambers. An external opening force can displace the valve element to open the flow connection and permit an automatic extension stroke of the piston rod. The valve element remains open during the extension stroke on account of the flow of blocking medium through the flow connection. The valve element can be displaced to close the flow connection in response to stopping the extension stroke of the piston rod to position ...

DOOR RETURN MECHANISM

... 1418825 Door closer springs J A THOMAS 5 March 1974 [13 Feb 1973] 7022/73 Heading E2M A door closer spring comprises door and frame attachment pivots 5, 10, a cylinder 1 and a rubber piston 2 which is carried on the end of a rod 8 in airtight engagement with the cylinder; opening of the door causing the piston to move away from a closed end of the cylinder against atmospheric pressure. All of the parts with the exception of the rubber piston are of plastics material (e.g. nylon) and a screw sealed vent 7 is provided to enable the piston to be re-set. Spring biassed balls 14 project slightly from the surface of the piston rod and cooperate with a piston stop 12 to damp closing movement. A piston stop 12 is secured to the open end of the cylinder.

PNEUMATIC SPRING

... 1529171 Gas springs with automatic mechanical locking AUTOMOBILES PEUGEOT 22 March 1977 [7 April 1976] 11943/77 Heading F2S In a pneumatic spring, particularly for actuation of pivotal panels of vehicles, wherein a piston 2 defines two gas containing chambers 7a, 7b with a cylinder 1, the piston 2 has an elastically yieldable device, such as skirt elements 8 with corresponding beads 10, which co-operates with a recess 11 formed in the cylinder 1 to maintain the spring in a position of immobilization.

LOCKABLE SPRING

... 1528820 Gas springs with automatic locking STABILUS GmbH 25 March 1976 [26 March 1975] 12040/76 Heading F2S A pneumatic or hydropneumatic pistoncylinder spring, for opening a vehicle boot or bonnet or a furniture flap as it extends, locks automatically when it has extended to a certain length, owing to closure of a flow path from one side of the piston to the other. In Fig. 1, on extension, a flow path provided by grooves 1 closes when the piston 5 reaches the portion 8, and so the spring is locked in this position unless a pull on the piston-rod 4 moves the piston into a further grooved portion, when extension will resume until the grooves are again closed off. On compression a one-way valve element 12 in the piston opens to render the locking inoperative. In Fig. 2, on extension, a flow path 17 through the piston 5 closes when an enlarged part 15 on a rod 14 fixed to the cylinder base meets a seal 20 in the piston. A pull on the piston-rod will move the seal past the part 15 to remove ...
