Abstract

1,109,639. Bowden mechanisms. FIRMA HEINZ SCHURMANN & CO. 28 March, 1967 [6 April, 1966], No. 14033/67. Heading F2K. A corner guide 1 for two rods 4, 5 connected by a flexible element comprises an anglehousing having shanks 2, 3 which form an acute angle with one another. As shown the angle is slightly less than 90 degrees. The housing includes a base-plate 7 to which a channel-shaped portion 6 is welded. The guide is used in mechanisms for activating and locking windows and doors.

1 2 The invention is based on the object of a patent claim: to design corner deflectors of the type mentioned in such a way that it can be fastened to the sash frame without screws. 1. Eckumlenker for the actuation and can be reinforced and for the, although its angle locking gear in windows, doors or the like., 5 housing a relatively large inner deflection radius consisting of an angular housing and two has, the associated corner of the sash | partially enclosed by the housing, does not need to be weakened. i flexible element connected deflection bar. This object is achieved according to the invention as a result gene, characterized in that the solves that the legs of the housing have a point Legs (2, 3) of the housing (1) form an acute angle that is a little less than 90 °, and Form an angle that is a little smaller than 90 ° so that the housing has flange strips on both sides] and that the housing has flanges on both sides, at least one side of which into one has made, of which at least the angular groove of the sash can be deflected. one side into an angular groove of the sash To easily insert the flange strips into the angular groove of the is deflectable. 15 to be able to snap in the sash frame is the groove 2. Eckumlenker according to claim 1, characterized ge held much larger than the thickness of the indicates that the housing (1) consists of a Bo flange strips. Due to the inclined position of the flange plate (7) and an upper, in cross-section most in the groove due to the acute angle, there is an arcuate part (6), and that the bottom nevertheless has a solid, tolerance-compensating, rattling plate (7) with the upper housing part ( 6) 20 free seat achieved under pretension,
