DE19858932A1 - Garage roll shutter with slat-holding blocks involves four-edged box profile blocks with weld on slat to prevent it sliding out through block ends in service. - Google Patents

Abstract

The block (2,3) consists of a four-edged box profile to hold the shutter slats inside against sideways shift, notably by means of a weld (4) and the block is slit lengthways (5) at the side facing the rear of the roll shutter. By tapering the blocks in their top part, they hinge onto one another. The block face turned towards the shutter shaft should be concave in an area between the slat holes. The block is recessed to the front and there closed off by the following shutter block when the roll shutter is fully extended.

Description

The invention relates to an improvement in a rolling grille and a method for the production.

Roller grilles are widely used, especially when closing parking garages and ga collar entrances.

Rolling grilles of known type consist of one another arranged at the height of the rolling grille netting and hinge-like interlocking block made of U-steel profiles. Correspond According to the width of the driveway to be closed, there are several such chain chains spaced from each other. Connecting element for the Block chains and at the same time hinge axis for each interlocking block are crossbars that are in the side of the entrance in the direction of movement of the rolling grille are guided and anchored against being pushed out or pulled out.

A lateral shift of the block on the cross bars and the cross bars in the up roll area, where there is no longer a lateral guide, is by an during assembly cross-sectional enlargement of the cross bars within selected U-steel Block prevented. This cross-sectional enlargement is done in the simplest way the application of a welding spot within the U-steel block on the by the fene U-profile easily accessible crossbar.

The disadvantage of this type of design of the rolling grille is that the U-profile executed block fill up with dust. This increases the maintenance effort.

The front and back of the rolling grilles also differ significantly in their Appearance. The front conveys a rod shape of the block chain, are on the back the individual blocks are clearly visible.

The object of the invention is to avoid these shortcomings. This task is solved with the characterizing features of claims 1 and 8, advantageous embodiments are the subject of the subclaims.  

In the rolling grille according to the invention, the height of the rolling grille is the same interlocking with each other and with the width of the rolling grille with one The spacing between the blocks, which are supported on crossbars, each consists of a square stenprofil, and the securing of the cross bars against lateral displacement is within of the square box profile of the block.

The securing of the crossbars against lateral displacement also takes place here in a be preferred embodiment by an applied weld spot, the cross cut the cross bars within the square box profile enlarged.

The advantages of the rolling grille according to the invention over the known solutions be are that while maintaining stability and ease of installation, the block wedges in the rolled-out state of the rolling grille on both sides the shape of a rod teln. Dust can only get into the block in the area where the block is hinge-like interlock, penetrate through narrow slits. The maintenance effort reduces significantly.

In a further embodiment of the invention it is provided that the square box profiles the block on the side forming the rear front of the rolling grille on a longitudinal slot point. This makes it possible to slightly adjust the width of the block at one end rejuvenate and easily the hinge-like meshing at the height of the Realize rolling grilles on top of each other - while maintaining the advantage le of the square box profile. The taper is preferably in the upper block area.

In a further advantageous embodiment of the invention, the area of the square is box profile of the block, which faces the roll-up shaft of the rolling grille, in block longitudinally concave. This makes rolling up easier, and the noise level when rolling up and down drops considerably.

According to the invention it is also provided that the block in its further embodiment a recess in the upper area of the square box profile on the front of the Have rolling grille, which is dimensioned so that the recess of a block through the following lower part of the following block in the rolled-out state of the rolling grille is covered.  

To manufacture the rolling grille, in which the assembly of the prefabricated parts in the we noticeable on a flat surface, the invention provides that the introduction securing the crossbars against lateral displacement when one is tilted Row of blocks compared to the previous row of pistons each through the recess from the front of the rolling grille.

An embodiment of the invention is shown in the drawing. Show it:

Fig. 1 shows a cross section through the roller grating,

Fig. 2 is a block chain and

Fig. 3 a block.

In Fig. 1 arranged on the crossbar 1 block 2 are shown. The crossbar 1 is guided laterally in the area of the entrance in the direction of movement through the profile 7 and ge conditions an pressing out or pulling by means of the head 8 anchored. Since the lateral Füh tion through the profile 7 in the area of the roll-up shaft of the rolling grille is no longer available, the cross bars 1 are secured against the block against lateral displacement. This is done by the welding point 4 applied in the square profile to the crossbar 1 , which increases the cross section of the crossbar 1 in this area.

Fig. 2 shows a block chain consisting of the blocks 2 , 3 , which interlock with one another on the crossbar 1 . The blocks 2 , 3 have a longitudinal slot 5 on the side forming the rear front of the rolling grille. This makes it possible to reduce the width of the blocks 2 , 3 , preferably in the upper hinge area, so that block 3 can reach over block 2 in a hinge-like manner. The direction of movement of the rolling grille was marked with B.

In the advantageous block embodiment shown in FIG. 3, the surface 6 of the four-sided box profile of the block 2 is concave in the block in the longitudinal direction on the side facing the winding shaft. In an advantageous embodiment, the surface 6 comprises an area between the bores for the cross bars 1 . Furthermore, the recess 10 can be seen on the block 2 in the upper region of the square box profile on the front of the rolling grille. This is dimensioned such that it is covered by the lower part of the block 3 following upwards in the rolled-out state of the rolling grille. Through this recess, the welding point 4 is introduced to secure the cross bars against lateral displacement in the tilted position of the block row opposite the previous row of ben ben row from the front of the rolling grille.
