DE19924549A1 - Window cross-head to hold roller blind; has two parts sliding together and connected by saw-tooth profiles, and has arrangement of bars on outer part to fix cross-head to window - Google Patents

Abstract

The window cross-head has two parts (1a,b) that slide together to fit different thicknesses. And are clamped by saw-tooth profiles (1f) on the bars of the parts. The outside part (1a) has inner bars (1i,j) that engage the window frame to secure the cross-head to the window. The window cross-head has two parts, which slide into each other to fit different window thicknesses. Each part has two blades (1c,d), which form a long groove (1e). The top of the lower blade of the outside part (1a) has a saw-toothed profile (1f) pointing outside the window. The bottom of the upper blade of the inside part (1b) has a mating saw-toothed profile (1f) pointing inside the window, so that the parts can be clamped together to secure the cross-head to the window. The window side of the upper part has spaced short (1i) and a long (1j) bars extending downards, which each have a triangular catch nose (1k), to engage catch noses of the window frame, and fix the cross-head vertically to the window.

Description

The invention relates to a window crossmember for receiving a revision cover on the one hand and as a stop for the roller shutter on the other hand and is also predestined for the integration of an insect screen roller blind.

Trusses in various forms are known as prior art, which are individually manufactured for different window thicknesses, whereby their attachment by means of clamping webs to the existing on the windows the opposite clamping lugs.

A disadvantage for the roller shutter builder is that the tra verses, the purpose of which is to accommodate the inspection cover in very under different strengths, both in depth and in height be, so that an individual, accurate measurement must take place.

Another disadvantage is that the groove cheeks very often protrude into the assembly room and thus due to the narrowed openings the assembly of the roller shutters very difficult.

The primary aim of the present invention is that the on groove for the inspection cover traverse any different Chen window thickness adjusts by a variable width and a unity Liche dimension of the groove is guaranteed, with the secondary task, a Roller shutters have a second stop opposite the roller shutter box wall to offer and optionally include an insect screen roller blind.

The invention is illustrated and explained in more detail with reference to drawings:

Fig. 1a, the assembled sections on a narrow window

Fig. 2 shows the assembled sections on an extremely strong window

Fig. 3 shows the cross member (1) to a window (2) with insect screen roller blind (3)

As can be seen in Fig. 1, the part of the window ( 2 a) belonging to the cross member ( 1 a) of the cross member ( 1 ) consists of a hollow body, of which a lower leg ( 1 c) extends in the horizontal plane to the inside of the fault ( 2 b) , an elongated groove ( 1 e) being formed at a parallel distance from the latter with a thigh ( 1 d). Here, the lower leg ( 1 c) has on its upper side a fine, sawtooth-shaped profile ( 1 f), the tips of which are directed towards the outside of the window ( 2 a).

In Fig. 1a the part of the window ( 2 b) associated ( 1 b) of the crossmember ( 1 ) is shown, the lower leg ( 1 c) is also equipped with a horizontal, sawtooth-shaped profile ( 1 f), the tooth tips point in the opposite direction to the inside of the window ( 1 b), which creates an indissoluble catch. The thigh ( 1 d) of the section ( 1 b) forms the basis of the molded groove ( 1 p) for the inspection cover.

Fig. 2 illustrates the union of the two sections ( 1 a) and ( 1 b) to the crossbeam ( 1 ), the joining being carried out so that the part ( 1 a) is first pressed onto the window ( 2 ), the from its underside ( 1 h) outgoing short web ( 1 i) with its locking lug ( 1 k) engages in the pre-existing on the outside of the window ( 1 a) lug ( 2 c). Then the section ( 1 b) with its lower leg ( 1 c) is inserted into the groove ( 1 e) existing on the section ( 1 a) and, with slight angling upwards, until it rests against the tensioning leg ( 1 g) on the outside of the window ( 2 b) moved and depressed until the leg (1 c) outgoing somewhat longer web (1 j), with its locking lance (1 k) into the grid lug (2 c) of the windowOn inner side (engages 2 b) whereby on the one hand the traverse ( 1 ) in itself and on the other hand with the window ( 2 ) is also united in the vertical direction.

In the narrow window ( 2 ) shown in Fig. 3, the same procedure applies, with the lower leg ( 1 c) of the section ( 1 b) penetrating to the end of the groove ( 1 e) of the section ( 1 a).

As is apparent from Fig. 4, the crossbeam (1) forms with its portion (1 a), or its over the window outer wall (2 a) projecting base leg (1 L) on the one hand the stop for a non-illustrated roller shutter and on the other hand, to the from it upward-pointing, short leg ( 1 m) and the just upright, long leg ( 1 n) with its notch ( 1 o) the attachment for an insect screen roller blind ( 3 ), which with its downward clamping leg ( 3 a) and its clamping nose ( 3 b) engages in the notch ( 1 o).

The crossbeam fulfills through adjustability, constant groove, roller shutter stop and the mounting profiles for insect screen blinds multifunctional tasks.

Claims (2)

1. Window crossbar - for receiving a roller shutter inspection cover on the one hand and as a stop for a roller shutter on the other hand, hereinafter called crossmember, characterized in that the crossmember ( 1 ) consists of two sections ( 1 a) and ( 1 b), which are in the horizontal plane against each other are introduced and can be moved and locked against different window thicknesses by each of the sections ( 1 a) and ( 1 b) each having two horizontally extending legs ( 1 c) and ( 1 d), which have an elongated groove ( 1 e) form, the lower leg ( 1 c) of the section ( 1 a) on its upper side with a fine, sawtooth-shaped profile ( 1 f) is formed, the tips of which point towards the outside of the window ( 2 ), while the lower leg ( 1 c) of the section ( 1 b) on its underside has an opposing profile ( 1 f), the tips of which are directed towards the inside of the window ( 2 ), so that when pushed together n under counter pressure the clamping legs ( 1 g) extending vertically downwards from the lower legs ( 1 c) of the sections ( 1 a) and ( 1 b) have a clamping effect, where after the traverse ( 1 ) with the window ( 2 ) in Horizontal direction is firmly connected -
