rolling gate

The invention relates to a roller shutter for gates and driveways, with a closing wall made of a flexible material, in particular one that can be rolled up in one direction, and with a rolling-up device for rolling up the closing wall in one rolling-up direction.

Flexible roll-up roller doors are well known, in which the part to be rolled up is rolled up on a rotating winding body arranged above the entrance, in the form of a well-known roller shutter. The disadvantage here is that the installation of such a door requires extensive conversion and installation work on the frame of the entrance. The complex assembly of the moving parts and the winding body for the flexible part that forms the door is particularly disruptive.

The object of the invention is to provide a roller door which can be installed without complex conversion measures and in which the parts of the roller door require as little space as possible in both the rolled-up and unrolled state.

5 The object is achieved by a roller shutter door according to claim 1.

According to the invention, the closure wall is firmly attached to the door or driveway frame at a horizontal longitudinal stop edge which delimits the closure wall and is oriented perpendicular to the rolling-up direction, and the rolling-up device has a winding body which is firmly connected to the closure wall along a fastening line which is horizontal to the delimiting longitudinal edge, approximately halfway along the length in the rolling-up direction of the closure wall, whereby the parts of the closure wall located above and below the winding body can be rolled up onto the winding body by a 5 rotational movement of the winding body about an axis of rotation, whereby

the winding body is mounted at the ends through which the rotation axis passes in a guide on the door or driveway frame so that it can move in the winding direction, which only allows movement of the winding body in the winding direction, whereby the rotational movement is imposed on the winding body by a drive arranged in the winding body.

An advantageous embodiment of the invention provides that the arranged drive is an electric motor with a housing and a rotating body, the housing of which is firmly connected to the winding body, wherein the rotating body is not rotatable about its own axis but is guided in the guide in the winding direction.

It is advantageous that the winding body is guided at one end so that it can rotate about its own (rotational) axis and can be moved in the guide in the winding direction.

According to a preferred embodiment of the invention, the closure wall is weighted by means of weights at the longitudinal edge which delimits it at the bottom.

According to a further preferred embodiment of the invention, it is provided that the closure wall is guided in the guide in the rolling-up direction at the longitudinal end edge delimiting it at the bottom.

Further advantages, special features and expedient developments of the invention emerge from the further subclaims or their subcombinations.

The invention is explained in more detail below with reference to the drawing. The schematic representation shows in detail:

Figures 1.1 and 1.2 show a roller door according to the invention for gates and driveways with a closure wall 21 and 22 in a front and rear view, whereby in the embodiment shown the closure wall is formed in one piece. The door frame and the guides to be attached to it are not shown here. The closure wall is attached along the longitudinal edge 11 of the stop, for example with screws.

ben attached to the door frame. To prevent the lower part of the closure wall 22 from bulging out in the wind, it is weighted and stiffened at the end longitudinal edge 12 with a weight body 12a, for example with a steel sheet.

The closure wall is rolled up (Figure 1.3) around the winding body 4 by rotating the latter about its axis of rotation D. By attaching the upper 21 and lower 22 parts of the closure wall along the fastening line 11 by means of rivets 23a, the outer side 111 of the closure wall and the inner side 112 are wound up lying on top of each other (see Figures 2.1 to 2.4).

The line C shows the position of the final longitudinal edge 12 in the fully unrolled state. At the same time as the final longitudinal edge 12, the winding body itself is raised horizontally in the direction of the fastening line 11 by the rotation of the winding body 4 and the rolling up of the upper part of the closure wall 21.

Figure 3.1 shows the guide 5 for the mandrel 41, which is firmly connected to the winding body 4. The mandrel can rotate in the guide 5 as shown in Figure 3.2, with the sides of the molded parts 522 and 521 of the guide 5 serving as contact edges 523 and 524, respectively.

Figure 4.1 shows the guide 6 on the side of the winding body 4 opposite the mandrel 41 and the guide 5. On this side, the rotating body 42 (motor rotor) is extended (for example by means of an extended axle). The rotating body is also rigidly connected to the carriage 43, which is guided in the guide 6 so that it can move in the winding direction (along the guide 6) (see also Figure 4.2).

Figure 5 shows a schematic cross-section through the winding body 4. The mandrel 41 is firmly connected to the winding body 4 with an end plate 411. The drive, designed as an electric motor 3, is located in the winding body 4. The housing 32 of the motor (stator of the motor) is firmly connected to the winding body 4 with fastenings 31. The rotating body 42 that is led out is in turn firmly connected to the carriage 43.

The motor rotates around itself with its housing because the rotating body 42 can only be moved in the longitudinal direction. By winding up and thus shortening the closure wall, the motor pulls itself towards the longitudinal stop edge.

The power supply can be provided simply by means of cables at one end of the winding body. To prevent the cables from being subjected to excessive strain by twisting, sliding contacts can be used here.
