Description

The 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 off Plastic profiles, in particular of flat hollow plastic profiles, are well known. One differentiates so-called roller shutter attachment boxes, which with a bottom base profile on the upper horizontal outside of a frame, and header boxes, which are usually of Outside in front of a frame extension or above the frame arranged aperture can be mounted.

Plastic roller shutter boxes usually have At the two end faces injection-molded head pieces or front hoods for recording the winding shaft for the roller shutter on while the individual panels or cover profiles in the extrusion process getting produced.

easy Shutter boxes each have a repository on the left and right half, very wide roller shutter boxes or shutter boxes for shared Window possibly also a center bearing, so that in boxes with a center bearing two separate roller shutter panels are used, which are in the respective marginal areas be guided by a simple and in the middle area by a double roller shutter guide rail.

In The side areas of a roller shutter box are usually Inlet funnels used that either stuck with the respective Front hoods are connected or slidable on the outer panel the roller shutter box are attached. In the middle area of a shared Roller shutter box is usually a center bearing with one piece molded funnel ver used. However, when using of roller shutter shells of different thickness each one adapted Center bearing can be used with appropriately sized inlet funnel.

State of the art

It has already been proposed, instead of a one-piece with the center bearing running inlet funnel to use a center bearing with separate inlet funnel, so that with different roller shutter tanks only one adapted Inlet funnel used in each case otherwise the same center bearing can be.

task

Gave up It is the object of the present invention to provide a feed hopper for a center bearing a roller shutter box as a separate component from the center bearing to disposal to provide, which has an optimized usability.

Presentation of the invention

The Invention solves this object 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 subject of the present application.

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

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

By folding the two halves of the inlet funnel they can thus be connected to each other, in particular locked and then form a (double) inlet funnel by pushing, latching, screwing o. The like. With egg can be connected to the center 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.

To a particularly preferred embodiment of the invention the two halves of the inlet funnel according to the invention however - in addition to the actual use as an inlet funnel for a central bearing - also separated from one another as inlet funnel in the side areas of a roller shutter box be used. This takes place in particular in applications, in those of the roller shutter not to the front hood of the roller shutter box is sufficient and thus the rolling chamber cover spaced from the front hood is used. These use cases occur in particular if due to the specific installation situation of the roller shutter box this has a greater width as the frame and therefore the side of the frame surmounted.

Best way to carry out the invention

The in the 1 to 3 illustrated inlet funnel according to the invention 1 was made by injection molding in one piece from polyamide.

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

The left half 2 and the right half 3 are through a movie hinge 14 connected with each other. The left half 2 and right half 3 consist essentially of the main body 4 . 4 ' the foot 5 . 5 ' , the inner deflector 6 . 6 ' , the outer deflector 7 . 7 ' , as well as a large collection lug 8th . 8th' for a fly screen. In this lug 8th . 8th' 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 1 and 3 It can be seen over the entire length of the outside of the outer deflector 7 . 7 ' extending locking ribs 16 . 16 ' as well as the guide ribs 15 . 15 ' leading to a corresponding guide groove 24 or locking groove 25 in the outer panel 23 of the roller shutter box 22 correspond (s. 11 and 12 ) and thus a simple, latching, possibly longitudinally displaceable connection between the inlet funnel 1 and the outer panel 23 enable. As in 1 to recognize, the body has 4 . 4 ' on one side a ribbing 9 . 9 ' for increasing the rigidity.

Of particular importance are the two holes each 12 . 12 ' on both feet 5 . 5 ' , alternately with one each spacer pin 13 . 13 ' and a locking pin 17 . 17 ' on both feet 5 . 5 ' the left or right half 2 . 3 of the inlet funnel 1 are arranged. In this case, the outer locking pin corresponds 17 ' with the outer hole 12 , the locking pin 17 with the appropriately arranged hole 12 ' , the spigot 13 ' again with the inner hole 12 and finally the spigot 13 with the inside hole 12 ' the opposite half 2 . 3 of the Einl auftrichters 1 , Also the two screw holes 11 . 11 ' with which the inlet funnel halves 2 . 3 at the base base profile ( 11 ) are on the left or right half 2 . 3 staggered to each other when folding the left half 2 with the right half 3 of the inlet funnel 1 not to collide with each other. Except for the spacers 13 . 13 ' , the locking pin 17 . 17 ' that correspond to holes 12 . 12 ' and the screw holes 11 . 11 ' are the left half 2 and the right half 3 of the inlet funnel 1 constructed mirror-symmetrically.

In the 5 to 9 is the intended use of the inlet funnel 1 in the folded and locked state together with the center bearing 19 shown in different views and sections. In 5 and 8th are two different views each before inserting 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 on the center bearing 19 grip the two mounting lugs 8th . 8th' the flat formed area of the center bearing 19 , in particular in 6 to recognize.

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

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

In this installation situation, only one half 2 of the inlet funnel 1 as - seen from the outside - right inlet funnel used. This half 2 will with the help of the screw 32 at the bottom base profile 30 screwed on and with the guide rib 15 in the guide groove 24 guided as well as with the locking rib 16 in the locking groove 25 the outer panel 23 of the roller shutter box 22 locked. In the right section of the drawing 11 you realize that the foot 5 together with the distance pin 13 and the locking pin 16 the inlet hopper half 2 exactly in the chamber 31 the roller shutter guide rail 27 fits. This is achieved because of the foot 5 the inlet hopper half 2 through the spigot 13 and the locking pin 17 almost doubled in thickness and thus has approximately the same thickness as the double foot 5 . 5 ' of the inlet funnel folded from two halves 1 (please refer 8th and 13 ).

In the 12 and 13 is the intended use of the invention (double) inlet funnel 1 together with the center bearing 19 shown with split roller shutter box. As in 13 to recognize, the illustrated shutter box 22 two shutter shafts 34 . 34 ' on, both from the center camp 19 being held. The tabs 21 support the center bearing 19 opposite the individual shutters of the roller shutter box 22 from. In particular from 12 you can see that from the two halves 2 and 3 existing inlet funnel 1 - as in 6 shown - firmly with the center bearing 19 connected is. In addition, the inlet funnel 1 outward with the guide rib 15 . 15 ' in the guide groove 24 held and with the locking ribs 16 . 16 ' in the locking groove 25 the outer panel locked.

In 13 is clear that the foot 5 . 5 ' of the inlet funnel 1 in the chamber 35 the roller shutter guide rail 33 to be led. In the folded state of the two halves 2 . 3 of the inlet funnel 1 equals the total thickness of the double foot 5 . 5 ' about the thickness of each foot 5 . 5 ' the two halves 2 . 3 together with the spacers 13 . 13 ' respectively.
