Abstract: Corner pieces for frames are used for joining together frame sides situated adjacent the corner piece. The frame sides are tubular or profile-shaped and adapted in their inner cavity to receive legs which are angularly arranged on the corner piece and interconnected by means of an intermediate part. Each leg consists of two parallel shanks and each shank is shaped so as to be complementary to the cavity of the frame side profile engaging the respective shank so that the shank can be inserted guidingly and with a certain friction in the cavity of the profile. The corner piece is composed of two identical corner parts interconnected by fastening means, the legs and the intermediate part of the corner piece having, on one hand, a first symmetry plane coinciding with the frame plane and, on the other hand, a second symmetry plane or bisector plane bisecting the angle between the legs of the corner piece. The second plane is perpendicular to the first symmetry plane.

Abstract: Means for coupling together two assemblies wherein the first assembly has an end wall formed by a first apertured plate, and the second assembly includes an end wall to which is secured a rotatable end plate. The rotatable end plate carries clamping means which can engage and clamp to apertures in the first apertured plate of the first assembly, whereby the two assemblies are coupled together. In using the apparatus, the two assemblies are positioned adjacent to each other with the rotatable plate and first apertured plate in alignment and the clamping means on the rotatable plate engaging apertures in the first apertured plate. Rotation of the rotatable plate then locks the assemblies together.

Abstract: A connection between a first member (e.g. a piston rod) and a bore in a second member (e.g. a piston) which is formed by two spaced grooves on the first member at least one of which is in register with one of two spaced steps in the bore, and a compression clip mounted in each groove such that when the groove and the step are in register the compression clip is in compression between one face of each groove and one face of the corresponding step and the angle between the compression forces acting on the clip and the longitudinal axis of the bore is in the range 30.degree.-70.degree..

Abstract: Improved apparatus is provided for temporarily securing together scaffolding members. A slotted stud fixed to a scaffolding support member is provided with a pivotal dog rotatable within the slot for receiving the hole punched end of a cross member. A spring and washer having a transverse bar member within the slot are permanently retained on the stud to prevent misuse of the device. Rotation of the dog to receive the cross member causes axial movement to the washer and compression of the spring. Further compression of the spring by the cross member allows the dog to return to its lock position by gravity. The spring, washer, and dog thus cooperate to either expel the cross member from the device or lock the cross member in place, which substantially increases scaffolding safety.

Abstract: The present disclosure describes a mechanism for positioning a pair of members in slip-free, adjustable, angular relationships. In accomplishing the foregoing, an assembly is provided which comprises a sphere and a pair of pivotally mounted jaw-like sections for engaging the latter. The inner surfaces of the sections have substantially the same radius of curvature as the sphere surface. Additionally, the sphere surface and the inner surfaces of the jaw-like sections are configured in respective interlocking patterns. Manipulation of the jaw-like sections allows the members to be placed in the desired angular position with respect to each other--which position is maintained by virtue of the aforementioned interlocking nature of the contiguous surfaces.

Abstract: A locking mechanism for a divided grip rod of a foldable baby carriage permits automatically locking the grip rod in an unfolded state and this locking can be canceled by a simple operation. The grip rod (2) is divided into two portions (2a, 2b), which are interconnected at their ends while being supported for rotation around the axes of parallel rotary shafts (6). Lateral surfaces of the ends of the portions of the grip rod intersect the rotary shafts. Each lateral surface has a locking recess (12). A locking plate (4) is movable axially of the rotary shafts so that it can fit simultaneously in the two locking recesses when the grip rod is in its straight state. The locking plate is urged by a spring in the direction in which it fits in the locking recesses for normally maintaining the locked state. An unlocking member (5) is provided to for disengaging the locking plate from the locking recesses against the force of the spring to permit folding of the grip rod.

Abstract: The subject of the invention is a ball joint for motor vehicles with a bearing shell arranged between a joint housing and a ball head. The shell is provided at one end with elastically deformable ribs projecting from a stop surface. So that the ribs, after compensating for production tolerances, can absorb, in the elastically deformable zone, additional axial shock loads occurring in driving operation, it is proposed that the ribs be designed as square ribs, running radially, and separated by grooves from the stop surface adjoining their side walls, while the volume of each rib projecting above the stop surface, before mounting, is approximately equal to the free volume of the two grooves adjacent to it, so that the side walls of the grooves lying next to the stop surface act in the mounted condition as support walls for the elastically deformed ribs.

Abstract: A locking mechanism for locking two foldable sections (2a, 2b) of a grip rod (2) of a baby carriage has two gears (26) meshing with each other. The grip rod sections are foldably interconnected by a coupling (12) which supports the gears (26) for rotation around their respective axes. One end surface of each gear (26) is formed with a locking recess (29) for receiving a locking plate (20) in the locked state. The locking plate is movable axially of the gears (26) for unlocking. The locking plate (20) is urged by a spring (32) into the locking recesses (29) to maintain the locked state. A push button (23) moves the locking plate (20) out of the locking recesses (29) against the force of the spring (32) to permit the folding.
