A manipulator for controlling a locking function and a maneuvering function of an access member rotatably coupled to a frame is disclosed. The manipulator includes an actuator configured to provide a substantially linear first actuating movement in a first direction and a substantially linear second actuating movement in a second direction, opposite to the first direction; a latch bolt functionally coupled to the actuator, the latch bolt arranged to move to an unlocking position in response to movement of the actuator in the first direction and arranged to move to a locking position in response to movement of the actuator in the second direction; and a transmission mechanism functionally coupled to the actuator, the transmission mechanism configured to transmit the first actuating movement in the first direction provided by the actuator to an opening movement of the access member. An access member, a system and a method are also provided.

A window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element may include first and second portions. The first portion may be coupled to the carrier. The mounting bracket may engage the second portion of the spring element and may selectively engage the carrier.

A device for assisting the opening and closing of a door in a structure. The device may comprise: a door shaft configured to rotate about a longitudinal axis thereof in both a first direction and in a second opposite direction, and configured to be mounted to the structure to form a hinge about which the door may rotate in the both the first and second directions relative to the structure; a first actuator linked to the door shaft and configured to control a speed of rotation of the door shaft in the first direction; and a second actuator linked to the door shaft and configured to drive rotation of the door shaft in the second direction. The second actuator is an electromechanical actuator.

A door hinge has a first leaf assembly, a second leaf assembly and a link assembly for pivoting of the first leaf assembly on the second leaf assembly between an open position and a closed position. This link assembly in turn has a first hinge link and a second hinge link pivoted about a connecting axis on the first link. The first hinge link is formed with a contact face that in the open position flatly engages a contact face of the second hinge link. This the first contact face also is formed with a projection that in the open position engages complementarily in a recess formed in the second hinge link.

A door hinge has a first leaf assembly, a second leaf assembly, and a link assembly connected to the leaf assemblies for pivoting of the second assembly on the first assembly. An adjuster in the first leaf assembly can displace the link assembly relative to the first leaf assembly and thereby adjust a position of the door in the frame. The adjuster has an adjusting element projecting from the first leaf assembly in the closed position. The second leaf assembly is formed with a recess in which the projecting adjuster engages in the closed position.

A door hinge has a first leaf assembly having a base frame, a second leaf assembly, and a link assembly connecting the leaf assemblies pivotally to each other. A first end of the link is pivoted on the seat block in the first leaf assembly. The seat block is movable in the base frame for adjustment in a first direction, and a guide formation preventing movement of the seat block in a second direction relative to the base frame.

A hinge has first and second leaf assemblies pivoted on each other and a link assembly interconnecting the first and second leaf assemblies. At least one of the first and second leaf assemblies has upper and lower mounts forming a cavity in which a respective end of the link assembly is pivoted, and at least one of the mounts of the one leaf assembly is formed with a recess opening into the cavity. According to the invention a body of foaming fire-protection material is provided in the recess so that when heated the body expands and fills the cavity with fire-protective foam.

A structure for shielding a rail includes a rail configured to be mounted on a vehicle body, a drive unit movably connected to the rail, a swing arm rotatably connected to the drive unit and a sliding door, a shade bar configured to be in contact with the swing arm and connected to the drive unit so as to be movable in a first direction in which the shade bar moves close to the rail or a second direction in which the shade bar moves away from the rail, and a cover having a first end connected to the shade bar, the cover configured to open or close a space in which the rail is positioned in accordance with a movement of the drive unit.

A passage barrier includes two guide elements that cooperate such that they define a gate region, through which a person passes from an entrance region into a passage region. The passage barrier has a drive with a drive unit and an output unit. The drive unit, output unit, and a barrier element are operatively connected such that the barrier element is movable via the drive unit into a position closing and a position opening the gate region. The output unit has a hollow shaft with outer and inner shell surfaces. The inner shell surface and drive unit are configured such that the inner shell surface surrounds the drive unit and the hollow shaft has a mount for fixing the barrier element on the hollow shaft. The mount is arranged on the outer shell surface and formed integrally with the hollow shaft.

A mechanism for influencing the opening and/or closing movement of a wing of a door, a window or the like comprises a sliding arm disposed between the wing and a fixed frame, being mounted rotatably on one hand on the wing or frame and on the other hand, guided by a sliding block in a sliding rail disposed on the frame or wing. Here, energy conversion means are assigned to the sliding rail and/or the sliding block, through which the kinetic energy of the sliding block can be converted to electrical energy, and electrical energy produced in this way can be converted to mechanical energy, in order to supply at least one electrical component with electric current, to generate a braking torque and/or to drive the sliding arm, at least in sections, especially to support the closing and/or opening movement.
