Abstract: Disclosed is a buttock support for at least partial load-relief of the body weight of a person, the buttock support having two support regions adapted to receive at least part of a buttock region of the person. Also disclosed is a load-relief system having the aforementioned buttock support. The two support regions are separated from one another by a gap and are rounded. The gap separates the two support regions from one another centrally. The buttock support significantly simplifies the connection of a person to the aforementioned load-relief system to prepare for manual and/or automated physical therapy and also ensures that the thigh region, in particular the inner face of the thigh, and the groin region are accessible for further medical/therapeutic treatment by the medical staff.

Abstract: The method for the manufacture of wall connector pieces is based on a thin-walled tubular blank which is first reduced in diameter at least one, preferably both ends in order to increase the wall thickness. In this way, a basis is provided for further shaping, for example, the manufacture of a connector piece (4) or a closed end (5).

Abstract: Devices and methods for manufacturing fittings (2) with different ends (3, 4) are disclosed, such fittings permitting different measures of connection. For example, one fitting (2) is a threaded end connector with its one end (4) being potentially configured as a compression fitting and its other end (3) as a thread-bearing end. An intermediate section (5) having preferably a polygonal cross-section is provided between the two ends (3, 4). Starting with a pipe piece (1), the manufacture takes place in a few process-safe method steps.

Abstract: A fitting for connecting pipes together. The fitting includes a press-fit connection including a ring-shaped seat configured to receive at least one of sealing and holding elements. The fitting is configured to be sealingly connected to an inserted pipe end. A threaded connection is configured to be connected to a pipe by a thread on the threaded connection. The fitting is a single piece and is devoid of weldments.

Abstract: A method for manufacturing a fitting. The method steps include: providing a pipe section; pressurizing the pipe section; forming a first end of the pipe section to create a press-fit connection having a smooth-walled seat for insertion of at least one of sealing and holding elements; forming a middle section to create a pipe-like polygonal-shaped element and a thickened section adjacent to the polygonal-shaped element; and cutting in a thread on a second end of the pipe section, thereby creating a fitting having a press-fit connection and threaded connection.

Abstract: A flange connection for pipes, especially for sanitary installations. The flange connection comprises a connecting piece which can be joined at each end to a pipe to produce a sealed connection. The flange connection further comprises a flange which is arranged radially outside on the connecting piece and which is fixable to a further component to make an indirect connection between the connecting piece and the further component. The flange has an opening through which the connecting piece is guided and the flange is fixed on the connecting piece by a retaining element.

Abstract: A fitting for the connecting of pipes comprises a press-fit connection (2), on which there is a ring-shaped seat (3) for sealing and/or holding elements and which is sealingly connectable to an inserted pipe end by means of cold forming. The fitting (1) also comprises a threaded connection (10), which is connectable to a pipe by means of a threaded connection, wherein the fitting (1) is produced in a single piece by means of forming, preferably by means of hydroforming. The fitting (1) can thereby be effectively produced with different connections.

Abstract: A composite tube includes at least two linings, wherein the first lining is an inert lining and wherein the second lining is placed radially outside of the first lining. A technical goal is to make available a composite tube, which provides an inert conduit for the transported medium and which, upon bending, does not prematurely kink itself. This technical goal is achieved in that a third deformable lining is provided and in that the third lining is placed radially outside of the first lining and is bound to the intervening second lining.

Abstract: A flange connection for pipes, especially for sanitary installations, including a connecting piece (1), which can be joined at each end to a pipe to produce a sealed connection, and a flange (2), which is arranged radially outside on the connecting piece (1) and which is fixable to a further component by a fixing device to make a connection between the connecting piece (1) and the further component. In order to provide a flange connection that is easy to assemble and manufacture, the flange (2) has an opening (20) through which the connecting piece (1) is guided and the flange (2) is fixed on the connecting piece (1) by a retainer (3).
