Abstract

The guide (1) has two halves (2, 3) arranged in a mirror-symmetrical manner and connected with each other by an integral hinge (14). The halves include base bodies (4, 4'), bases (5, 5'), inner guide rods (6, 6') and outer guide rods (7, 7'), where the bases include spacer elements and recesses. The spacer elements are arranged corresponding to the recesses such that the spacer element of one of the halves is engaged in the recess of the other halve during folding of the halves on each other. The spacer elements are formed as catch pins.

Description

The invention relates to an inlet funnel for a center bearing of a roller shutter box as a separate component from the center bearing.

Technical area

Roller shutter boxes made of plastic profiles, in particular of flat hollow plastic profiles, are well known. A distinction is made between so-called roller shutter top boxes, which are mounted with a bottom base profile on the upper horizontal outside of a window frame, and header boxes, which are usually mounted from the outside in front of a Blendrahmenverbreiterung or above the window frame arranged aperture.

Plastic roller shutter boxes usually have on the two end faces injection-molded head pieces or front hoods for receiving the winding shaft for the roller shutter, while the individual panels or cover profiles are produced by extrusion.

Simple roller shutter boxes have on the left and right half each a repository, very wide roller shutter boxes or roller shutter boxes for split windows possibly also a center bearing, so that in boxes with a center bearing two separate roller shutter armor are used, in the respective edge areas by a simple and be guided in the central area by a double roller shutter guide rail.

In the side areas of a roller shutter box funnel are usually used, which are either fixedly connected to the respective end caps or which are slidably mounted on the outer panel of the roller shutter box. In the middle area of a divided roller shutter box, a center bearing with integrally molded inlet funnel is usually used. However, when using roller shutter shells of different thickness, a respectively adapted center bearing with a correspondingly dimensioned inlet funnel must be used.

State of the art

It has already been proposed to use a central bearing with separate inlet funnel instead of an inlet funnel, which is made in one piece with the center bearing, so that only one adapted inlet funnel can be used in each case with the same center bearing at different roller shutter armor.

task

The object of the present invention is to provide a feed hopper for a center bearing of a roller shutter box as a separate from the center bearing member having an optimized usability.

Presentation of the invention

The invention solves this problem by an inlet funnel according to claim 1, preferably with one or more of the features of the subclaims. Furthermore, the use according to claim 4 or 5 is the subject of the present application.

The inlet funnel according to the invention can be used in two different situations, namely on the one hand in the folded state in the region of the center bearing, as separate inlet funnel halves but on the other hand also in the edge region of a roller shutter box as left or right "normal" inlet funnel.

The inlet funnel according to the present invention consists of two substantially mirror-symmetrical halves, which are interconnected by a film hinge according to a preferred embodiment of the invention are and can be folded so that they form a double inlet funnel for a center bearing. For this purpose, the two halves each have a substantially planar main body with one foot, wherein the foot of the respective halves each have at least one spacer element and at least one recess. According to a preferred embodiment of the invention, at least one of the spacer elements is designed as a latching pin, which forms a latching connection with a corresponding recess of the respective other half of the inlet funnel, in particular a hole. In particular, this corresponding recess is a hole whose diameter is slightly smaller than the outer diameter of the locking pin. Preferably, the foot region additionally has, as a further spacer element, at least one spacer pin, which in turn corresponds to a corresponding hole in the other inlet funnel half. According to this particularly preferred embodiment of the invention thus latching pin and spigot of the two halves of the inlet funnel according to the invention are offset from one another, in this detail, the two halves are thus not mirror-symmetrical to each other.

By folding the two halves of the inlet funnel they can thus be connected together, in particular locked and then form a (double) inlet funnel, which can be connected by sliding, locking, screwing o. The like. With a central bearing. For differently sized roller shutter rods then suitably adapted inlet funnel are used, the distance between inner deflector and outer deflector is adapted to the thickness of the roller shutter rods used.

According to a particularly preferred embodiment of the invention, however, the two halves of the inlet funnel according to the invention can - in addition to the actual use as inlet funnel for a central bearing - also be used separately as inlet funnel in the side areas of a roller shutter box. This is done especially in applications where the roller shutter does not reach to the front hood of the shutter box and thus the rolling chamber cover is used spaced from the front hood. These applications occur in particular when, due to the specific installation situation of the roller shutter box, this has a greater width than the frame and therefore projects laterally beyond the frame.

Best way to carry out the invention

The in the Fig. 1 to 3 represented inlet funnel 1 according to the invention was made in one piece by injection molding of polyamide.

The inlet funnel 1 has two halves 2, 3, which are constructed largely mirror-symmetrical to each other and optionally in accordance with use with a center bearing 19 Fig. 11 collapsed by folding to a double inlet hopper 1 or alternatively accordingly FIGS. 12 and 13 can be used individually as a side inlet funnel.

The left half 2 and the right half 3 are connected to each other by a film hinge 14. The left half 2 and right half 3 consist essentially of the base body 4, 4 ', the foot 5, 5', the inner deflector 6, 6 ', the outer deflector 7, 7', and a large receiving lug 8, 8 ' for a fly screen. In this receiving lug 8, 8 'are the receiving holes 10, 10' for a corresponding pin in the edge region of a fly screen - not shown in the figures - provided.

In Fig. 1 and 3 recognizes the over the entire length of the outer side of the outer deflector 7, 7 'extending locking ribs 16, 16' and the guide ribs 15, 15 ', which correspond to a corresponding guide groove 24 and locking groove 25 in the outer panel 23 of the shutter box 22 ( s. Fig. 11 and 12 ) and thereby allow a simple, latching, possibly longitudinally displaceable connection between the inlet funnel 1 and the outer panel 23. As in Fig. 1 to recognize, the base body 4, 4 'on one side a ribbing 9, 9' to increase the rigidity.

Of particular importance are the two holes 12, 12'auf the two feet 5, 5 ', which alternately with a respective spacer pin 13, 13' and a latching pin 17, 17 'on the two feet 5, 5' of the left or right half 2, 3 of the inlet funnel 1 are arranged. In this case, the outer latching pin 17 'corresponds to the outer hole 12, the locking pin 17 with the correspondingly arranged hole 12', the distance pin 13 'turn with the inner hole 12 and finally the spacer pin 13 with the inner hole 12' of each opposite half. 2 , 3 of the inlet funnel 1. Also the two screw holes 11, 11 ', with which the inlet funnel halves 2, 3 on the base base profile ( Fig. 11 ) can be fastened, are arranged on the left and right half 2, 3 offset from one another to not collide with each other when folding the left half 2 with the right half 3 of the inlet funnel 1. With the exception of the distance pin 13, 13 ', the locking pin 17, 17', the corresponding holes 12, 12 'and the Schraublaschen 11, 11' are the left half 2 and the right half 3 of the inlet funnel 1 constructed mirror-symmetrically.

In the Fig. 5 to 9 is the intended use of the inlet funnel 1 in the folded and locked together state shown together with the center bearing 19 in different views and sections. In FIGS. 5 and 8 are two different views in each case before the onset of the inlet funnel 1 on the center bearing 19 and in the 6 and 9 each presented after insertion. When sliding the inlet funnel 1 onto the center bearing 19, the two receiving lugs 8, 8 'embrace the flat region of the center bearing 19, in particular in FIG Fig. 6 to recognize.

The center bearing 19 has on both sides a ribbing 20, which gives it an increased stability with low construction weight.

In the Fig. 10 and 11 is the alternative use of the left half 2 of the inlet funnel 1 shown in a mounting situation in which the shutter box 22 on its - seen from the outside - right side over the frame 28 and in which therefore the roller shutter not - as usual - to the front hood 29, but only approximately up to the offset relative to the front hood 29 arranged rolling chamber cover 26. Accordingly, the roller shutter guide rail 27 extends laterally to the left offset to the front hood 29th

In this installation situation, only one half 2 of the inlet funnel 1 as - seen from the outside - right inlet funnel is used. This half 2 is screwed by means of the screw 32 to the base base profile 30 and guided with the guide rib 15 in the guide groove 24 and locked with the locking rib 16 in the locking groove 25 of the outer panel 23 of the shutter box 22. In the right section of the drawing Fig. 11 it can be seen that the foot 5 together with the spacer pin 13 and the locking pin 16 of the inlet funnel half 2 fits exactly into the chamber 31 of the roller shutter guide rail 27. This is achieved because the foot 5 of the inlet hopper half 2 is almost doubled in its thickness by the spacer pin 13 and the locking pin 17 and thus has approximately the same thickness as the double foot 5, 5 'of the inlet hopper 1 folded from two halves (please refer Fig. 8 and 13 ).

In the FIGS. 12 and 13 the intended use of the invention (double) inlet funnel 1 is shown together with the center bearing 19 in split roller shutter box. As in Fig. 13 to recognize the illustrated shutter box 22 has two shutter shafts 34, 34 ', both of which are held by the center bearing 19. The tabs 21 support the center bearing 19 relative to the individual panels of the roller shutter box 22. In particular from Fig. 12 is to realize that consisting of the two halves 2 and 3 inlet funnel 1 - as in Fig. 6 shown - is firmly connected to the center bearing 19. In addition, the inlet funnel 1 is held outwardly with the guide rib 15, 15 'in the guide groove 24 and engaged with the locking ribs 16, 16' in the locking groove 25 of the outer panel.

In Fig. 13 is clarified that the foot 5, 5 'of the inlet funnel 1 in the chamber 35 of the roller shutter guide rail 33 is guided. In the folded state of the two halves 2, 3 of the inlet funnel 1 corresponds to the total thickness of the double-foot 5, 5'etwa the thickness of each foot 5, 5 'of the two halves 2, 3 together with the distance pin 13, 13' or locking pin 17, 17 '.
