Abstract:
A device for connecting rod- or plate-shaped building components is provided with a gripping unit (1, 2) and an insert (5, 6). The insert (5, 6) is preferably spherical or polyhedral and can be introduced in various positions in an appropriate clamping region of the gripping unit (1, 2). The clamping region is accessible in five different mutually perpendicular or antiparallel spatial directions (7.1, ..., 7.5).
Abstract:
A construction system comprises rod components (7.1 - 7.4) which can be connected by means of angular coupling units (8.1, 8.2, 8.5, 8.6) to be arranged in nodal points. The rod components (7.1 - 7.4) are provided at their extremities with a plurality of coupling connections (13.1, 13.2) arranged around the longitudinal axis of the rod, and in these connections the coupling units can be fixed in a plurality of angular positions. The coupling units are preferably two-arm angles.
Abstract:
A process and a system are disclosed for controllable supplying or evacuating breathing air. The system has a mask (10) and a device (11, 12) for holding the mask before the mouth and/or nose area of the user. The edge of the mask is spaced apart from the mouth and/or nose area of the user, at least in partial zones. An air duct (14) for the controlled supply of surrounding air or for sucking off breathing air opens into the mask.
Abstract:
Joint for joining several beams (1, 1a) in a beam, especially bars in a framework, by means of connectors attached to the beam edge or end, having at least partially a basic body with one or more wall sections arranged obliquely in relation to the beam axis and/or side for supporting neighbouring similar connectors or other bodies within the joint at the wall sections. The superimposed wall sections are transfixed and held together by fasteners and each fastener is fitted and/or guided in an access channel which runs from the oblique wall section through the inside of the basic body to the outside of the joint.
