Abstract: A work surface is provided with a lock assembly. The lock assembly includes an actuator plate and a locking plate. The actuator plate includes a pin. The locking plate includes an angled slot that receives the pin of the actuator plate. Actuation of the actuator plate in a first direction causes the pin to move within the angled slot of the locking plate. The movement of the pin within the angled slot causes movement of the locking plate in a second direction, thereby actuating the locking plate between a locked configuration and an unlocked configuration.

Abstract: An adjustable gate is provided. The adjustable gate includes a body having an upper horizontal element and a lower horizontal element. The body also includes a first vertical side member, and a second vertical side member, with the upper and the lower horizontal elements moveably coupled to the first and second vertical side members. A hinge post has a first elongated member having a hinge and an adjustable hinge post mounting tab. A latch post has a second elongated member having a latch apparatus and an adjustable latch post mounting tab. The adjustable hinge post and latch post mounting tabs are structured to couple to a mounting surface, and the hinge is structured to couple to either the first or second vertical side members and the latch apparatus is structured to removeably couple to either the first or second vertical side members.

Abstract: An extendible barricade including a housing having a first panel located within the housing that is extendable from the housing, a second panel located within the housing that is extendible from the housing, wherein the housing is releasably attached to an overhead door by means of an attachment assembly. Furthermore, an associated method is also provided.

Abstract: The present invention relates to a gate. More specifically, the present invention relates to a gate having at least one arm, wherein the at least one arm is configured to extend and retract. When the at least one arm is substantially extended, the at least one arm substantially prevents access through the gate. When the at least one arm is substantially retracted, the at least one arm no longer substantially prevents access through the gate.

Abstract: The present invention relates to a self-contained protection device (1, 1a-1b) for provisionally blocking a passage (10) such as a corridor, a door, or a window, characterized in that it includes at least one longitudinally-extendable bar (2, 2a-2b), preferably a telescopic bar, the extension thereof being actuatable by an actuator (3), said bar being capable of being removably locked in an extended configuration between two wall surfaces (10a, 10b) defining said passage, referred to as locking surfaces, said extendable bar supporting one or preferably a plurality of blocking member(s) (4) to form a protection screen (5, 5a, 5b) blocking said passage, in which said blocking member(s) is or are preferably removably fixed.

Abstract: The present invention is a door assembly including a rectangular door frame, a bi-fold door pivotally mounted at the top of the rectangular door frame and at least one hydraulic cylinder assembly. The hydraulic cylinder assembly is pivotally secured by a first end to a cylinder support mounted on a back side of the door frame, and by a second lower end to a cylinder support secured to a back surface of a top panel of the bi-fold door. In the door closed position, the longitudinal axis of the cylinder is oriented at an acute angle away from a plane defined by the door pivot axis and the lower pivot axis of the cylinder. A hydraulic control assembly controls movement of the door between an open and closed position.

Abstract: A weight compensation system is provided for a motor driven door having a door leaf that is driven by a mechanism inside guide rails on a side of the door leaf to move the door between an opened position and a closed position. The weight compensation system includes a weight-compensation device comprising a cable unit and a spring unit arranged at least on one side of the door leaf, wherein the cable unit comprises a single cable. A cable-tension compensation device at which the single cable is deflected creates two cable strands that are secured against breakage within the cable-tension compensation device. The cable-tension compensation device is positioned locally fixed or secured to the door leaf so that two cable strands move at a distance to each other, and the exposed ends of the cable are guided together and attached to the door leaf or are positioned locally fixed, respectively.

Abstract: A movable barrier operator (10) has a first disconnect mechanism (20) and a second disconnect mechanism (35) wherein either mechanism can be used to cause the output drive of the operator to be disengaged from the movable barrier to allow the movable barrier to be manually moved. In one embodiment, the second disconnect mechanism (35) is located distal to the operator itself such that the disengagement mechanism can be operated from an area external to the operator.

Abstract: A security gate includes an installation and release mechanism that is operable with one hand. The gate comprises two panels which are extendible with respect to each other and lockable in the extended position. This makes it possible for the gate to expand across a wide variety of door openings. A handle located centrally on the top of the gate is connected by a pair of cranks and a pull rod to a pair of plungers which contact one side of the door frame. Spring bias on the plungers normally force the plungers into contact with the door frame. Slots in the upper and lower plunger links permit the plungers to accommodate irregular door frames. The handle is employed to withdraw the plungers from contact with the door frames and, conversely, the absence of handle pressure causes the gate to position itself solidly against the vertical door jamb. The handle is also employed by the operator to carry and position the gate in the doorway, allowing one-handed operation.

Abstract: A protective cover system for use in connection with guiding paths of machine tools including a plurality of overlapping cover plates telescopically moved into and out of each other while each cover plate at its front end face rests on the guiding path and at the rear end rests on the next segmental cover plate. Between the individual cover plates there are arranged energy storing means the return force of which is zero in the intermediate position of said energy storing means whereas the return force of said energy storing means is at its maximum in the fully pulled-out or pushed-in position of said cover plates. Each energy storing means includes a cylinder with an inserted elastic body and a piston. Between the cylinders and the piston at least one cam segment is provided. Relative movement between the cylinder and the pertaining cam segment is brought about by fork-shaped rods linked with the arms of said fork-shaped rods to the front end faces of the cover plates.

Abstract: A roof for a motor vehicle, particularly a passenger motor vehicle which possesses an area to be opened intermediate the windshield and a roll-over girder disposed within the area of the rear window; the area to be opened in the roof is subdivided into two sections which are adapted to be displaced telescopically and can be retracted one within the other into the area of the roll-over girder so as to be completely covered by the outer member of the roll-over girder; the roll-over girder together with the outer covering member thereby preferably forms a hollow body.
