Abstract: A ground-penetrating radar device comprises a frame, a radar antenna, and an antenna assembly, wherein the antenna is part of the antenna assembly. Further the GPR device comprises a mount for adaptively mounting the antenna assembly to the frame and a ground support for supporting the frame on the ground. In an operational state, the mount prevents a horizontal displacement of the antenna assembly relative to the frame in two horizontal directions. In the operational state, the mount further allows a vertical displacement of the antenna assembly relative to the frame and a tilting of the antenna assembly relative to the frame.

Abstract: The rinsing device comprises a flexible connecting pipe which at one end is connected to a connecting element which may be attached to a fitting and at the other end bears a spray head with an actuating lever. The spray head is held on a holder, which protrudes outwardly from the connecting element. The connecting pipe comprises a flexible water feed pipe which is surrounded by a casing element, which is formed by a single spiral tension spring consisting of one piece. Said spiral tension spring consists of a first upright spring portion having a straight spring axis, a second curved spring portion attached thereto and a third, similarly upright spring portion having a straight spring axis, which is attached to the second spring portion. A tube-shaped protective casing extends around the casing element which protects the casing element from soiling.

Abstract: The spray attachment has a holding part with a water guide that can be connected to a feed water pipe, and a spray head with an external housing. Said spray head and the holding part are fastened separably to each other by means of a coupling. Furthermore, the spray head can have switching options for producing different spray jets, and an illuminating means.

Abstract: The spray head has a housing-mounted inflow passage for feed water, and a central first outflow passage. A second and a third outflow passage are offset in the circumferential direction with respect to an axis of rotation. Each of the outflow passages is connected to a corresponding water outlet for producing different spray jets. A control element having a connecting channel is disposed in the interior of the spray head and is rotatable about the axis of rotation by the actuating element. The actuating element can execute a lifting movement. In the starting position of the actuating element, the connecting channel exclusively connects the inflow passage to the first outflow passage. In the lifting position of the actuating element, the inflow passage is connected either to the second or the third outflow passage as a function of the actuating element and the associated rotational position of the control element.
