Abstract: An assembly for the transfer of operating movement around the corner of a window or door, particularly tilt/turn closures, involves an angled casing, guiding a flexible deflection member, which connects the operating rods of the closure. An intermediary connecting member between the flexible deflection member and an operating rod forms a slide bolt, preferably a tilt-lock locking-slide, which is stiffened by a longitudinal batten. The batten fits in a slot on one leg of the angled casing. The sliding bolt engages the flexible member by means of a cam-and-recess. The batten stabilizes the flexible member when it is under compression. The assembly and the sliding bolt are shaped to allow insertion in grooves in the profiles which form the closure frame. A clamping piece holds one of the legs in the frame. Elements of the assembly assist in dispersing transverse forces which can cause binding.

The window fitting includes a flat belt revolving in the casement of the window in a guide channel with inserted corner turning facilities, the flat belt being rigidly connected with a driving lug for the operating handle, the lock pin of the lock facility, a lock element of the tilting facility and with a lock element of the scissors-type lever system for tilting the window.

Abstract: In a swing-tilt fitting for mounting the wing of a window or door to its frame, an arresting means is provided which is operatively associated with the locking rod linkage which controls the operational mode of the wing. Since between every two of the three positions (closure, swinging, tilting) of the operating linkage a lost motion is present, the locking rod linkage can be utilized for actuating the arresting means. Said arresting means can be disposed either laterally between the wing and frame of a window or a door or between tilt shears and members disposed in the upper locking rod channel. The tilt position, which can be stepwise or infinitely variable, is secured by actuating the operating grip of the linkage out of the tilt position into one of the two other positions, closure or swinging. The tilt arrest is effected either by engagement of tooth members or by turning a brake member guided in a hollow rod.

Abstract: An opening pivot mechanism for a window or any type of closure that permits the closure to be opened in three directions from a single operator that includes three actuator rods with integral cylindrical bosses that define two pivot pins on each of three axes for slotted hinges carried by the closure. The actuator rods are simultaneously reciprocated by the operator through a series of links to position one of the rods with its pivot pins in their associated hinges thus defining the selected pivot axis, and to position at the same time reduced portions on the other two actuator rods in the remaining hinges so these rods can pass through the slots in their hinges during opening movement of the closure.

Abstract: The novel arrangement relates to a skylight with a case and a wing mounted thereon for pivoting about a horizontal axis and swinging about a further horizontal axis, the swinging axis being partially constituted by axial pins at the sides of the wing which are displaceable while supported on the case, with a cover partially overlapping the wing and case, the cover being pivotally linked at one end to the case and at the other end at the wing, the axial pins being arranged between the linkages and the wing having a guard for covering the case at least in the range not overlapped by the cover, with at least one weight balancing device arranged on one of the longitudinal struts of the wing whose two-armed support lever pivotal about a bearing pin consists of a support arm carrying a roller and a tension arm to which a tension spring is linked which is adjustable by means of a tensioning device affixed to the wing.

Abstract: In skylights wherein the wing may be selectively adjusted into a pivoting and swivel position, the wing is fixed with respect to the auxiliary frame in the pivoted opened position. If this fixation is removed due to a faulty operation, the upper, heavier half of the wing moves in the direction of the case so that there is a danger of damage. To make the negative effects of the faulty operation ineffective, flap 18 provided with latch 19 and having a pivoting axis displaced in relation to axial pin 7 in the direction of swivel joint 5 is pivotally mounted on auxiliary frame 2. Latch 19 arranged at a slight distance from axial pin 7 in the closed position subtends axial pin 7 when wing 3 is pivoted open. In case of a faulty operation, the weight of wing 3 causes axial pin 7 to be pressed against latch 19 of flap 18. This automatically secures a pivotally opened skylight against the results of a faulty operation, which is automatically undone, FIG. 4, when the wing is brought into the closed position.

Abstract: Push bar fittings which extend in longitudinal grooves of the frames of windows, doors, or the like, are provided with holding means by which ribs projecting from the side walls of the groove are engaged from below, with the push bar being mounted for displacement above the ribs. To provide as wide a range as possible for cutting the push bar to length, and, on the other hand, to obtain a good guidance of the push bar ends in spite of that, the push bar is provided at the level of the ribs with a portion correspondingly sloping toward the groove bottom. Consequently, the free end of the push bar then extends in the groove portion below the ribs and is thus prevented from moving out of the longitudinal groove.

Abstract: A safety apparatus which includes a gate positioned adjacent the free edge of a loading dock and swingable between a substantially horizontal position wherein it is adapted to extend across the rear of a truck, and a vertical position permitting access between the dock and the truck. In a preferred embodiment, the swinging movement of the gate is controlled by an electrical switch mounted on a wheel chock located within the truck parking area. When a truck is positioned adjacent the dock, the chock is wedged in front of the truck tire. This causes activation of the switch so that a motor is energized to cause the gate to be swung upwardly into an approximate vertical position. Whenever the switch is released, as due to removal of the chock from engagement with the tire, then the motor is automatically reversely energized to swing the gate into its lowered horizontal position.
