Abstract:
A mechanism for self-latching access doors of a safety cabinet following sequential self-closing of the doors. Latching takes place between the doors and at a top and bottom frame of the cabinet. A latching arm and two actuating arms extend from a bellcrank which is biased toward a latched position. An interference bar prevents rotation of the bellcrank to the latched position when the doors are open. Upon sequential self-closing of the doors an actuating means slides the interference bar to a position of non-interference with the bellcrank which enables the self-latching action to take place.
Abstract:
An internal entrapment system (10) for a door (12) movable by a repeatable force includes a force generating device (68) for transferring the door (12) between a first and a second position. A trolley arm (34) connected between the force generating device (68) and the door (12) is continually strained during movement of the door (12). A sensor (50) mounted on the trolley arm (34) generates a signal (54) representative of the strain applied to the trolley arm (34). A processor (72) receives the strain signal (54) for comparison to a predetermined threshold, when the strain signal (54) exceeds the predetermined threshold, the processor (72) at least stops the force generating device (68). A potentiometer (74) is coupled to the door (12) for determining a plurality of positional locations of the door (12) between the first and the second positions, wherein the processor (72) correlates the position of the door (12) with the strain signal (54) for use in comparison to the predetermined threshold. A power supply (64) provides electrical power to the force generating device (68), the sensor (50), the processor (72), and the potentiometer (74), and a decoder/amplifier circuit (70), which also receives electrical power from the power supply (64) and receives the strain signal (54) for conversion into a format acceptable for use by the processor (72).
Abstract:
A bracket assembly for an overhead door including a first portion having a first base and at least two first portion rails having a plurality of openings. At least two arm attachment projections extending outwardly from the first base substantially parallel to the rails each including an opening. The assembly further including a second portion having a second base and at least two second portion rails having a plurality of openings. The second portion also includes at least two pivot pin receiving projections each having at least one opening. A third portion of the bracket assembly includes a third base having at least two third portion projections having at least one opening. The third portion can be attached to the second portion by a pivot pin.
Abstract:
A swinging-sliding door for vehicles, particularly for passenger vehicles, includes two door leaves positioned outside and within the wall of the vehicle in a closed state. For the door, a driving device for operating the door leaves includes pivotable, roller carrying levers which swing the door leaves from the closed position into a ready-to-open position; in addition, the driving device exerts a reaction force onto the pivotable roller carrying levers which, in closed position, results in locking them, a driving device includes a single electro-motor and gearing unit positioned laterally above the opening of the door, further having a case and a driving pulley, a traction belt is guided through a deflection pulley and couples the drive pulley to the door leaves via the roller carrying levers; the case has a flange carrying an eccentric control pin engaging a control lever fastened to a door post carrying the pivotable roller-carrying lever, and the control pin in a door closing position being held in a dead center position in a curved contour of the control lever so that the door is safely locked and can neither be opened manually nor by forces of the wind.
Abstract:
A computer including a keyboard portion and a display portion is interconnected in a manner which provides dual positions operational. In one position the keyboard portion may be horizontally positioned to facilitate the entry of data via the keyboard. In the other position, the display portion may be horizontally positioned to facilitate the entry of data or graphic designs via the interaction of a graphics pen over the display. Advantageously, the interconnection mechanism which provides the two positions maintains the readability of the display and the keyboard portions in either of the two positions.
Abstract:
A garage door locking device (10) includes a bracket (12) for connection to a garage door (12) and translating initial push/pull movement of a first push/pull cable (20) into locking and unlocking actuation of a latch member (30), respectively. The bracket (32) includes a slot defining a track having closed ends at each end thereof for stopping and engaging a follower member (44) mounted thereon. A second push/pull cable (48) has a first end connected to the follower member (44) and a second end connected to a latch member (30) so that the follower member (44) is biased towards one of the closed ends of the slot (40) when the latch member (30) is engaged to lock the door and the follower member (44) engages the other closed end of the slot (40) when the latch member (30) is disengaged from the locked condition.
Abstract:
A sliding door structure suitable for furniture and the like, comprises a first door (1) and a second door (2), respectively slidable on a pair of parallel, spaced upper guides (4,6) and a pair of parallel, spaced lower guides (3,5). The said first door (1) is connected to rollers (17), which roll on the guides (4), by a mechanism (10-40) able to cause a coplanar positioning of the doors (1,2) in the closure position, and displacement of the first door (1), substantially perpendicularly with respect to the door translation direction, to superimpose the first door (1) over the second door (2) during opening of the doors themselves.
