A cupboard-shaped piece of furniture (1) includes side walls (2), on each of which a control mechanism (4) for the displacement of a door leaf (7) is arranged, whereby the control mechanisms (4) are connected by means of a synchronisation rod (10) for the synchronised movement thereof. The synchronisation road (10) includes a fixing device (12) on at least one end region for the detachable connection of the synchronisation rod (10) to a rotating piece (17) of the control mechanism (4), the fixing device (12) being embodied such that the synchronisation rod (10) may also be connected to the rotating piece (17) when the rotating piece (17) is already pre-assembled on a side wall (2) of the piece of furniture (1).

A flap drive for a flap includes two identical lever joint arrangements which are arranged in pairs at a distance from one another. The flap can be moved out of its closing position into its opening position and back by the flap drive. In this case, the lever joint arrangements are articulated pivotably with one of their ends in each case on a side region of the flap and with their other ends at a fixed location on the motor vehicle. The mutually corresponding pivot axes of the articulation points extend coaxially to one another. Movement transmission devices for the pivotable drive of a driven lever of each lever joint arrangement are guided by a common motive drive unit, the driven levers being articulated at a fixed location on the motor vehicle.

A four bar link is provided between a walled cargo area of a truck and a rigid rear cargo door. The effective length of the lower link of the four bar linkage is longer than that of the upper link such that the motion of the door is generally up and over the top of the truck body. An eccentric cam is joined to the upper link with a tensioned spring extending around the cam such that the spring slackens as the door opens. The cam is configured so that, as the door is opened, the spring slackens more slowly initially then more quickly. This allows the door to be moved initially mostly outwardly before moving significantly upwardly and still be effectively counterbalanced throughout its motion.

First and second generally harp shaped guard halves, one being formed with a vertical mounting flange for attachment to the garage door jamb adjacent the hardware to be shrouded and each being formed with co-extensive planar walls projecting along the opposite sides of the hardware and formed with inturned peripheral flanges rounding the top and vertical length thereof for complementally mating together to generally shroud the hardware within such guard apparatus.
摘要:
A spring assembly for use in place of the spiral tension springs in conventional spring-loaded counterbalancing systems for garage doors. It is made up of a compression spring and traveling pulley in a tubular housing, the compression spring being mounted above the pulley. A cable extends around the pulley from an anchored end to interconnection with the kicker assembly of the mounting hardware for tension springs in an ordinary garage door counterbalancing system so that closing of the door causes the cable to pull up on the pulley and compress the spring. There is virtually no possibility that the compressed spring will rupture and emit flying fragments, but even if this occurred the housing would prevent the escape of such fragments to the surroundings.

A device for securing and tensioning garage door springs in place including a cross-bar member, a downwardly extending rod threadably connected at one end to the cross-bar member and having a hook at the other end adapted to engage an anchor bracket, a pair of spaced upwardly extending threaded rods which protrude through apertures in the cross-bar and have hooked upper ends adapted to be connected to the springs, and nuts on each of the lower ends of said threaded rods adapted to engage the lower face of the cross-bar so that the threaded rods may be axially adjusted relative to the cross-bar.

THE APPLICATION DISCLOSES A DEVICE FOR SECURING GARAGE DOOR SPRINGS IN PLACE INCLUDING A THREADED ROD HOOKED AT ONE END AND HAVING A SLIDEABLE SLEEVE THEREON PROVIDED WITH AN OPPOSITELY FACING HOOK TOGETHER WITH NUTS THREADED ON THE ROD BEYOND EACH END OF THE SLEEVE.
摘要:
AN OVERHEAD GARAGE DOOR HINGING SYSTEM HAVING A SPRING FASTENER FOR ADJUSTABLY COUPLING COUNTERBALANCE SPRINGS TO A POWER ARM. THE SPRING FASTENER INCLUDES A PAIR OF SIDE PLATES BETWEEN WHICH THE POWER ARM IS PIVOTABLY MOUNTED THROUGH ONE OF A PLURALITY OF HOLES IN THE POWER ARM. A PLURALITY OF OPENINGS ARE SO SPACED ALONG THE SIDE PLATES THAT EACH OF THE OPENINGS ARE ALIGNED WITH A DIFFERENT ONE OF THE HOLES IN THE POWER ARM AT ONE POSITION OF THE HINGING SYSTEM, WHEREBY THE POINTS OF ATTACHMENT OF THE SPRINGS TO THE POWER ARM MAY BE CHANGED WITHOUT DISCONNECTING THE SPRINGS. THE COUNTERBALANCE SPRINGS ARE CONNECTED TO THE GARAGE STRUCTURE BY MEANS INCLUDING A SPRING-CONNECTING MEMBER AND A SLOTTED MOUNTING BRACKET WHICH ARE ADAPTED FOR ACCOMMODATING A TENSION-ADJUSTING TOOL FOR REPOSITIONING THE CONNECTING MEMBER, AND THEREFORE ADJUSTING THE TENSION OF THE SPRINGS. A SPRING SPREADER, HAVING SPRING-CONNECTION LUGS MOUNTED ON A SHAFT SO AS TO CONVERT ROTATIONAL MOTION OF THE SHAFT INTO LINEAR DISPLACEMENT OF THE LUGS, IS PROVIDED FOR CONVENIENTLY INSTALLING THE COUNTERBALANCE SPRINGS. A MOUNTING MEMBER POSITIONING TOOL IS FURTHER PROVIDED FOR RELEASABLY ENGAGING ONE LEG OF A MOUNTING BRACKET OF THE HINGING SYSTEM, SO THAT THE GARAGE DOOR MAY BE DETACHED AND REINSTALLED WITHOUT DISCONNECTING THE SPRINGS FROM THE SYSTEM.
