Abstract: A transport cart having a base assembly, having two opposing side assemblies arranged on the base assembly, having a respective wheel arranged on a respective one of the side assemblies, and having at least one receptacle arranged between the side assemblies for a respective transport box. The transport cart is transferable between a packing mode and a first operating mode or between the first operating mode and a second operating mode. A method for transferring such a transport cart between the first operating mode and the second operating mode, a method for transferring such a transport cart between the packing mode and the first operating mode, and a method for transforming such a transport cart are also disclosed.

Abstract: A C-frame press having a press frame, a first ram device, an opposed second ram device, and a drive device for moving at least one of the ram devices in a pressing direction. The press frame has first and second bending bars connected to each other by a tension column and a pressure column which together define a frame plane extending parallel to the pressing direction. The tension column is connected to each of the first and second bending bars by a bearing which is torque-free about an axis which extends perpendicularly to the frame plane. The first and second ram devices are each supported on the press frame by a bearing which is torque-free about an axis which extends perpendicularly to the frame plane. At least the at least one movable ram device is guided in a linear guide which extends parallel to the pressing direction.

Abstract: An articulation mechanism has a central part and a head part each made of a pair of shaped elements. The pairs of shaped elements form inner and outer shells. The inner shells are positioned inside the outer shells. The pairs of shaped elements are pivotable relative to one another and lockable relative to one another in several positions in one pivot direction. The outer shells have inwardly oriented projections and the inner shells have openings. A slide is moveably arranged inside the inner shells. The slide has locking members projecting through the openings of the inner shells and engaging intermediate spaces of the projections. A spring acts on the slide in an engagement direction of the locking members relative to the projections. The projections are shaped such that the locking members automatically reach a locking position in a first pivot direction of the head part.

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 hinge, particularly for an article for lying, sitting, and the like, has a hinge part supporting a rest member and turnable between and arrestable in a plurality of positions, a power element turning the hinge part in closing direction, an arresting element for arresting the hinge part, and a turnable intermediate element cooperating with the hinge part and arranged so that it supports the hinge part in its turning direction or is coupled with the hinge part in one turning region between a substantially horizontal and a substantially vertical position of the rest member, and the hinge part is separately turnable in a remaining turning region.
