Abstract: A door hinge which stops the swing-open motion of a door before it can strike an adjacent wall located at ninety degrees to the closed door. By stopping the motion of the door at ninety degrees, the protruding hardware of the door will not penetrate or otherwise damage the adjacent wall. Frequent repairs are therefore avoided. The door hinge is adaptable to various residential and commercial applications.

Abstract: In order to achieve the situation where a pivotably mounted structural part, under the action of an adjusting force, is made to move indeed automatically but merely with braking and damping action, and thus at a reduced speed and with reduced kinetic energy, provision is made for the hinge which mounts the structural part to be equipped with a pivot brake, of which the braking force applied over the pivoting distance is smaller than the adjusting force and is adapted to the progression of the adjusting force over the pivoting distance. In selected regions, the braking force of the pivot brake may be greater than the adjusting force, in order to retain the structural part in these regions. The braking work performed by the pivot brake is advantageously calculated so as to absorb 20% to 25% of the adjusting work performed by the adjusting force.

Abstract: A joint or articulation (1), especially for connecting sidepieces of a multi-purpose ladder that can be folded up, has two joint legs (2, 3) that are pivotable relative to one another about a joint shaft (4). One of the joint legs (2) forms an outer joint portion having outer shells (7) and a joint connector (8), while the other joint leg (3) is embodied as an inner joint portion having inner disks (9) and joint connectors (10). A spring-loaded locking member (24) is movable essentially radially or tangentially relative to the joint shaft (4) and is engageable in at least one recessed portion (42) of one joint leg (2). In order to achieve a simpler construction of the joint or articulation (1), recessed portions (12) are provided in the inner disk (9), whereby the locking member (24) extends transverse to the plane of the inner disk through the recessed portions (12). The locking member (24) cooperates with a lever (20) that is pivotable about a journal (19) that is spaced from the joint shaft (4).

Abstract: A double pivotable door, particularly for use with modular office partitions is disclosed. The double pivotable door includes a frame, which is mounted to a partition by at least one hinge having a first axis of rotation. The frame include a door which is mounted to the frame and can rotate about a second axis of rotation, where the second axis of rotation is parallel but spaced from the first axis of rotation. The door can thus be mounted to partitions where there is limited space, and can rotate about the first axis, as a typical door, or rotate about the first and second axes simultaneously, thereby reducing by approximately half the clearance required for opening and closing the door. Preferably, the door includes a mechanism to prevent the door from pivoting about the second axis. Also preferably, the handle for the door is integral therewith.

Abstract: The present invention relates to a safety hinge mechanism for foldable play yard and that is used to pivotally connect a first frame rod and a second frame rod thereof. The connecting bracket can be selectively rotated along the longitudinal axis of the frame rod into a locking position, or a neutralized position. A locking device is provided and disposed onto any one of the first and second frame rods. The locking device can be moved along the longitudinal direction into a locked position, or a released position. Wherein in the locked position, the locking device is engaged with the connecting bracket and the connecting bracket is prevented from any rotational movement thereof. As a result, the first and second frame rods are allowed to fully extend while they are not allowed to fold together. However, when the locking device and the connecting bracket are disengaged, the connecting bracket is rotated to a neutralized position and the first and second frame rods can be folded in a side-by-side manner.
