Casing for slip coupling used to secure greenhouse screen to drive wire, contains cavity in wall for drive wire, and receiving spaces for clamping pieces and spring, and guide for one clamping piece

摘要

The casing (45) comprises a die with a wall containing at least one cavity (111) for locating a drive part extending through the casing, a first receiving space (112) formed inside the casing for a first clamping piece (80), and a second receiving space formed inside the casing for a second clamping piece, the receiving spaces being located on either side of the cavity. A guide for at least one of the clamping pieces is formed inside the casing and extends transverse to the direction in which the cavity is oriented. A third receiving space is formed inside the casing for a spring (100) and forms an extension of the first and second receiving spaces. Independent claims are also included for the following: (1) Slip coupling for securing a screen inside a greenhouse to a drive member such as a wire, comprising this casing; and (2) Greenhouse with screen profiles connected to their drive members via these slip couplings.
