Description

The invention relates to a guide rail device for laterally guiding a roller shutter or rolling grille curtain of a roller shutter or rolling grille.

Roller doors have a roller door curtain or roller door curtain as the door leaf, which is connected from several articulated slats, which can be wound onto a winding shaft for opening the roller door and unwound from the winding shaft to close the roller door. Such roller doors open vertically and hardly require any space. Due to their construction principles, they offer maximum space in and in front of the building that can be locked with the roller shutter.

The invention has set itself the task of reducing the noise generated when opening or closing roller doors and rolling grilles and the wear and tear on components of rolling doors and rolling grilles, as well as increasing their service life.

To achieve this object, the invention creates a guide rail device for laterally guiding a roller shutter or roller grille curtain of a roller shutter or roller grille according to claim 1.

Advantageous configurations are the subject of the subclaims.

According to one aspect, the invention creates a guide rail device for laterally guiding a rolling shutter or rolling grille curtain of a rolling shutter or rolling grille with a guide rail for vertically guiding the rolling shutter or rolling grille and an inlet funnel for guiding the rolling shutter or rolling grille into an entry area of the guide rail, the inlet funnel is movable relative to the guide rail, and a damping body connected to the inlet funnel, which dampens vibrations and shocks of the inlet funnel.

One embodiment of a roller door has a roller door curtain with slats connected to one another in an articulated manner. The guide rail device is also suitable for guiding a rolling grille with grille slats of a rolling grille curtain that are connected to one another in an articulated manner.

On both sides of the roller shutter or rolling grille, in particular vertically extending guide rails are attached to the sides of the building opening to be closed with the rolling shutter / rolling grille for the lateral guidance of the slats.

When the roller shutter / rolling grille is opened or closed, the slats of the roller shutter or rolling grille curtain are wound or unwound from a winding shaft arranged in the upper area of the building opening.

When the roller shutter or rolling grille curtain is rolled up or unrolled from the winding shaft of the roller shutter / rolling grille, the diameter of the roll of the rolling shutter or rolling grille that is rolled up on the winding shaft changes.

To guide the roller shutter or rolling grille curtain into the entry area of the guide rail, an inlet funnel attached to the guide rail is provided, which directs the roller shutter or rolling grille curtain into the vertical guide rail.

One idea of the invention is now to decouple the inlet funnel from the guide rail so that the inlet funnel is movable relative to the guide rail.

Furthermore, a damping body is provided on the inlet funnel, which dampens vibrations and shocks of the inlet funnel.

The retraction angle of the roller shutter or rolling grille curtain relative to the guide rail can vary when the roller shutter or rolling grille curtain is rolled up or down from the winding shaft, since the diameter of the barrel of the roller shutter or rolling grille curtain on the winding shaft can change.

The mobility of the inlet funnel makes it possible for the inlet funnel to adapt to the draw-in angle of the roller shutter or rolling grille curtain relative to the guide rail.

This reduces the wear on the roller shutter or rolling grille curtain and / or the inlet funnel. Furthermore, the development of noise is reduced.

In order to further reduce the development of noise, a damping body is advantageously provided on the inlet funnel, which dampens vibrations and shocks of the inlet funnel.

It is preferred that the guide rail and the inlet funnel are connected to one another via a joint.

It is preferred to connect the guide rail and the inlet funnel to one another via a joint. The joint enables the inlet funnel to be movable relative to the guide rail.

It is preferred that the damping body is an elastic connecting element that connects the guide rail and the inlet funnel to one another is formed and the guide rail and the inlet funnel are brought into engagement with one another via the connecting element.

One embodiment of the invention consists in that the damping body is arranged between the guide rail and the inlet funnel and connects the guide rail and the inlet funnel to one another.

This connecting element can be elastic, so that both a movement of the inlet funnel relative to the guide rail and a damping of the vibrations and shocks of the inlet funnel are achieved by the elasticity of the connecting element.

It is preferred that the connecting element is fastened to the guide rail and / or the inlet funnel via screw connections.

It is preferred that the connecting element can be plugged into or onto the guide rail and / or the inlet funnel.

It is preferred that the damping body is made from an elastomer.

It is preferred that the guide rail is designed in the form of an elongated U with two opposite rail legs connected via a web and that a rail leg sliding profile is provided on the inner sides of the rail legs for the low-friction sliding along the roller shutter or rolling grille curtain.

The roller shutter or rolling grille curtain is guided between the opposite rail legs of the guide rail.

For the low-friction sliding along the roller shutter or rolling grille, rail leg slide profiles, for example made of plastic, are provided on the insides of the rail legs directed towards the roller shutter or roller grille.

It is preferred that the inlet funnel has two opposite funnel elements which are inclined and / or curved in the direction of the outside of the rail legs of the guide rail.

The inlet funnel preferably has two opposite funnel elements.

The funnel elements are preferably inclined and / or curved towards the outside of the rail legs of the guide rail. The funnel elements thus form an inlet area of the inlet funnel that is open at an angle. This enables the roller shutter or rolling grille curtain that can be rolled up or unrolled from the winding shaft to enter the inlet funnel at different angles.

The funnel elements can for example be made of metal, plastic or an elastomer or combinations thereof.

For example, the funnel elements can be made flexible from rubber. As a result, the funnel elements can be movable relative to the guide rail and the movement of the funnel elements is damped.

The funnel shape of these funnel elements is used to guide the roller shutter or rolling grille curtain. The dynamic adaptation of the movably mounted and / or flexibly designed inlet funnel improves this effect considerably by better distributing the forces that occur and thus making the rolling shutter or rolling grille run more smoothly and reducing the load on the rolling shutter or rolling grille.

It is preferred that the funnel elements each have a funnel element sliding profile for the low-friction sliding along the roller shutter or rolling grille curtain and / or that the funnel elements are connected to one another via a profile in the form of an elongated U.

In one possible embodiment, the inlet funnel has a cross-section, like the guide rail, in the form of an elongated U profile on. For example, the funnel elements can be attached to the profile of the inlet funnel.

For the low-friction sliding of the roller shutter or rolling grille curtain in the inlet funnel, funnel element sliding profiles can be attached to the inside of the two opposite funnel elements.

It is preferred that the connecting element is designed in the form of an elongated U with a web, two opposite legs and an opening for the passage of the roller shutter or rolling grille curtain.

The guide rail, the connecting element and the inlet funnel can therefore preferably be designed with profiles in the form of an elongated U. The roller shutter or rolling grille curtain can then be guided through the opening and laterally on the legs of the profiles.

It is preferred that the rail leg sliding profiles and / or the funnel element sliding profiles protrude beyond the guide rail or the inlet funnel and the protruding area of the rail leg sliding profiles or the funnel element sliding profiles is arranged on the inside of the legs of the connecting element so that the roller shutter or rolling grille armor when passing through the opening of the connecting element can slide along the rail leg sliding profiles and / or the funnel element sliding profiles.

Extended funnel element sliding profiles and / or rail leg sliding profiles also enable the rolling shutter or rolling grille to pass through the connecting element with little friction.

According to a further aspect, the invention creates a roller shutter or rolling grille with a first guide rail device and a second guide rail device, the guide rail being the first Guide rail device are attached laterally to the building opening to be closed off with the roller shutter or rolling grille and the guide rail of the second guide rail device is attached laterally on the opposite side of the building opening to be closed off with the rolling shutter / rolling grille.

In other words, the invention creates a roller shutter / rolling grille with flexible funnels.

Another idea of the invention is to decouple the inlet funnel of a guide rail device for roller shutters / rolling grilles both mechanically and acoustically.

One aim of the invention is to separate the guide rail and the inlet funnel in terms of their mobility and sound transfer in order to reduce operating noise or noise emissions, reduce wear and thus extend the service life of a roller shutter or rolling grille.

When implemented, the invention includes both articulated mounting and decoupling, for example via individual joints, and rubber mountings.

When the individual slats of the roller shutter or rolling grille profiles hit the inlet funnel, forces and thus noise and wear are generated in a rigid inlet funnel.

The functional principle of the flexible funnel is based on the fact that the flexible inlet funnel converts part of this energy released by the forces into motion and thus reduces the noise and wear on the door or grille curtain and on the funnel or the sliding profiles of the inlet funnel.

In the following an embodiment of the invention is explained with reference to roller doors. Nevertheless, it goes without saying that the invention can also be applied to rolling grilles.

Fig. 1 shows a representation of a guide rail device 10 for a roller door 11 according to an embodiment of the invention.

The guide rail device 10 has a guide rail 12 in the lower area of the illustration. The guide rail 12 has a profile 14 which is U-shaped in cross section and which is elongated. The profile 14 of the guide rail 12 has a web 16 and two opposite rail legs 18, 20.

In the upper area of the representation of Fig. 1 an inlet funnel 22 is shown.

The inlet funnel 22 has two opposite funnel elements 24, 26. How out Fig. 1 As can be seen, the inner surfaces 28, 30 of the funnel elements 24, 26 are each curved in the manner of a runner in the direction of the outside of the rail legs 18, 20.

The inlet funnel 22 also has a profile 32 which is likewise U-shaped in cross section.

The U-shaped profile 32 is in particular made rigid, i.e. not elastic.

In the embodiment shown, the funnel elements 24, 26 are fastened to the profile 32 of the inlet funnel 22 with screws. Alternatively or in addition, the funnel elements 24, 26 can also be fastened to the profile 32 of the inlet funnel 22 in some other way, for example slipped on.

The funnel elements 24, 26 can be made of metal or plastic, for example.

Due to the fixed connection between the U-shaped profile 32 and the funnel elements 24, 26, these are designed as rigid, inelastic and firmly interconnected components of the inlet funnel 22.

The inlet funnel 22 is connected to a damping body 34. In the exemplary embodiment, the inlet funnel 22 is fastened to the damping body 34 with screws 36, 38.

The damping body 34 can also have a profile 40 with a U-shaped cross section, although other configurations of the damping body 34 are also conceivable.

The damping body 34 is preferably made of an elastomer.

At the in Fig. 1 The embodiment of the guide rail device 10 shown here, the damping body 34 is also connected to the guide rail 12 via screw connections 42, 44.

The inlet funnel 22 can thus be connected to the guide rail by means of a joint 45. The joint 45 can, for example, be designed as a swivel joint, the inlet funnel 22 being rotatable about an axis of rotation.

In the embodiment shown, the damping body 34 connects the guide rail 12 and the inlet funnel 22 to one another. The damping body 34 therefore represents a connecting element 46.

The connecting element 46 has a web 48, two opposing legs 50, 52 and an opening 54.

Other constructions are possible. For example, the damping body 34 can also be attached to masonry or the like instead of to the guide rail 12 in such a way that there is no connection between the guide rail 12 and the inlet funnel 22.

A lining tube 56 can also be attached to one side of the guide rail 12.

Fig. 2 FIG. 11 shows an exploded view of the guide rail device 10 from FIG Fig. 1 .

As can be seen therefrom, the U-shaped profile 40 of the damping body 34 or the connecting element 46 is pushed over the U-shaped profile 14 of the guide rail 12 and over the U-shaped profile 32 of the inlet funnel 22. The screws 36, 38 and screw connections 42, 44 ensure that the inlet funnel 22 or the guide rail 12 is fastened to the connecting element 46.

From the Fig. 2 slide profiles 58 can also be seen. Rail-leg slide profiles 60, 62 are attached to the inside of the rail legs 18, 20.

In addition, funnel element slide profiles 64, 66 are arranged on the inner surfaces 28, 30 of the funnel elements 24, 26.

The sliding profiles 50 are preferably made of plastic.

The rail limb sliding profiles 60, 62 protrude from the guide rail 12 in the upper region thereof or are elongated. This leads to how Fig. 1 shown, in the assembled state of the guide rail 12 with the connecting element 46, the rail limb slide profiles 60, 62 also cover the region of the limbs 50, 52 of the connecting element 46.

As an alternative or in addition, the funnel element slide profiles 64, 66 can protrude or the connecting element 46 has separate slide profiles 50.

Fig. 3 shows the roller door 11 with a guide rail device 10 from the side, with a roller door curtain 68 on an in Fig. 3 is wound up by the roller shutter curtain 68 covered winding shaft 70 and the roller shutter 11 is in an open state.

The winding shaft 70 is usually located in the interior of a building opening to be closed with the roller door 11, which is in the Fig. 3 corresponds to the left side of the illustration. Accordingly, the right-hand side represents the outer space of the roller door 11.

Like in the Fig. 3 As can be seen, a bale 72 of the rolled-up roller shutter curtain 68 has a large diameter.

One end of the rolled-up roller shutter curtain 68 leads downward into the inlet funnel 22 of the guide rail device 10.

In this embodiment, between the winding shaft 70 or the bale 72 and the guide rail device 10, there is a free area of the roller shutter curtain 68 in which, due to the varying diameter of the bale 72, no lateral guidance is provided.

The roller shutter curtain 68 has a slightly negative draw-in angle relative to the guide rail 12 of the guide rail device 10.

The roller shutter curtain 68 therefore does not hang exactly vertically downwards, since the guide rail 12 of the guide rail device 10 is not oriented tangentially to the bale 72.

This is also shown in the enlarged illustration of the guide rail device 10 from FIG Fig. 4 evident. The lines drawn show the alignment of the vertical guide rail 12 and the roller shutter curtain 68 and enclose a slightly negative angle.

Since the connecting element 46 is elastic, the connecting element 46 is elastically bent by the negative draw-in angle of the roller shutter curtain 68.

The inlet funnel 22 accordingly adapts to the negative angle and inclines in the direction of the right side FIGS. 3 and 4 , ie for example in the direction of the outside space of a building opening to be locked.

Fig. 5 shows in analogy to Fig. 3 a side view of the roller door 11, the roller door curtain 68 now being unrolled from the winding shaft 70. The winding shaft 70 is now also visible.

The bale 72 is accordingly now empty.

The end of the roller shutter curtain 68 now enters the guide device 10 at a positive draw-in angle relative to the guide rail 12, since the Guide rail device 10 is not positioned exactly tangentially below winding shaft 70.

The connecting element 46 is elastically bent by the positive draw-in angle of the roller shutter curtain 68, here to the left in FIG Fig. 5 .

Fig. 6 finally shows an enlarged illustration of the guide rail device 10 from Fig. 5 . Here, too, the drawn lines indicate the alignment of the roller shutter curtain 68 relative to the vertical guide rail 12.

The inlet funnel 22 now adapts to the positive angle and also inclines in the direction of the left side Figures 5 and 6 .

When moving the roller door 11, the inlet funnel 22 is movable.

The sliding profiles 58, i.e. the rail leg sliding profiles 60, 62 and the funnel element sliding profiles 64, 66 enable the roller shutter curtain 68 to slide along in the guide rail device 10 with little friction.

During the process, the roller shutter curtain 68 passes the connecting element 46 through the opening 54 and slides therein on the extended rail leg slide profiles 60, 62.

When the roller shutter curtain 68 is moved, the inlet funnel 22 always adapts to the current retraction angle of the roller shutter curtain 68 relative to the guide rail 12 of the guide rail device 10.

The flexible inlet funnel 22 thus also adapts to the forces acting and absorbs part of the forces acting laterally of the roller shutter curtain 68.

This leads to a quieter operation of the roller door 11.

Furthermore, the wear on the roller shutter curtain 68 and on the inlet funnel 22 or the funnel element sliding profiles 64, 66 is reduced.

In order to dampen vibrations and shocks of the movable inlet funnel 22, the guide rail device 10 also has a damping body 34.

A further advantage of the invention is therefore that vibrations and shocks of the inlet funnel 22 are dampened by the damping body 34 connected to the inlet funnel 22 each time the roller shutter curtain 68 is deflected.

As a result, the sound transfer from the inlet funnel 22 to the guide rail 12 is attenuated or prevented.

In addition, the roller shutter curtain 68 is prevented from swinging when the roller shutter curtain 68 is moved in that area between the winding shaft 70 and the guide rail 10 attached to the building opening to be locked, where the roller shutter curtain 68 can move laterally due to the varying diameter of the bale 72 and the movable inlet funnel 22 .

An embodiment of the invention has been described above with reference to roller doors. For more detailed configurations of possible embodiments of such roller doors and also of roller grilles, reference is made to the company publication [1] mentioned at the beginning.

The invention is particularly suitable for industrial doors.
