DETAILED DESCRIPTION

(8) In the following, one embodiment of the invention is described with reference to rolling doors. Nevertheless, it is understood that the invention is also applicable to rolling grilles.

(9) FIG. 1 shows a representation of a guide rail device 10 for a rolling door 11 according to one embodiment of the invention.

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

(11) In the upper area of the illustration of FIG. 1, an infeed funnel 22 is shown.

(12) The infeed funnel 22 has two opposing funnel elements 24, 26. As can be seen from FIG. 1, the inner surfaces 28, 30 of the funnel elements 24, 26 are each curved in a skid-like manner in the direction of the outer side of the rail legs 18, 20.

(13) The infeed funnel 22 further has a profile 32 which is also U-shaped in cross-section.

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

(15) In the embodiment shown, the funnel elements 24, 26 are attached to the profile 32 of the infeed funnel 22 by screws. Alternatively or additionally, the funnel elements 24, 26 can also be attached to the profile 32 of the infeed funnel 22 in another way, for example by being plugged on the profile.

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

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

(18) The infeed funnel 22 is connected to a damping body 46. In the exemplary embodiment, the infeed funnel 22 is attached to the damping body 46 by screws 36, 38.

(19) The damping body 46 can also have a profile with a U-shaped cross-section, although other designs of the damping body 46 are also conceivable.

(20) Preferably, the damping body 46 is made of an elastomer.

(21) In the embodiment of the guide rail device 10 shown in FIG. 1, the damping body 46 is also connected to the guide rail 12 via screw connections 42, 44.

(22) The infeed funnel 22 can thus be connected to the guide rail via the damping body 46, constituting a joint. The joint can, for example, be designed as a swivel joint, whereby the infeed funnel 22 can be rotated about an axis of rotation.

(23) In the embodiment shown, the damping body 46 connects the guide rail 12 and the infeed funnel 22 to each other. The damping body 46 therefore constitutes a connecting element. Hereinbelow, to describe this embodiment, the terms damping body 46 and the connecting element are used interchangeably.

(24) The damping body 46 has a web 48, two opposite legs 50, 52 and an opening 54.

(25) Other constructions are conceivable. For example, instead of being attached to the guide rail 12, the damping body 46 can also be attached to masonry or the like in such a way that there is no connection between the guide rail 12 and the infeed funnel 22.

(26) Furthermore, a relining tube 56 may be attached to one side of the guide rail 12.

(27) FIG. 2 shows an exploded view of the guide rail device 10 of FIG. 1.

(28) As can be seen therefrom, the U-shaped profile of the damping body 46 or the connecting element is slid over the U-shaped profile of the guide rail 12 as well as over the U-shaped profile 32 of the infeed funnel 22. The screws 36, 38 and the screw connections 42, 44 provide a fastening of the infeed funnel 22 or the guide rail 12 to the connecting element.

(29) FIG. 2 also shows sliding profiles 58. Rail leg slide profiles 60, 62 are attached to the inside of the rail legs 18, 20.

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

(31) Preferably, the slide profiles 50 are made of plastic.

(32) The rail leg sliding profiles 60, 62 protrude from the guide rail 12 in the upper region thereof or are extended. As a result, as shown in FIG. 1, in the assembled state of the guide rail 12 with the connecting element, the rail leg sliding profiles 60, 62 also cover the region of the legs 50, 52 of the connecting element.

(33) Alternatively or additionally, the funnel element sliding profiles 64 66 may protrude or the connecting element may have separate sliding profiles 50.

(34) FIG. 3 shows the rolling door 11 with a guide rail device 10 from the side, wherein a rolling door armor 68 is wound on a winding shaft 70 concealed by the rolling door armor 68 in FIG. 3 and the rolling door 11 is in an open state.

(35) The winding shaft 70 is usually located in the interior of a building opening to be closed with the rolling door 11, which corresponds to the left side of the illustration in FIG. 3. Accordingly, the right side represents the outer space of the rolling door 11.

(36) As can be seen in FIG. 3, a bale 72 of the coiled rolling door armor 68 has a large diameter.

(37) One end of the coiled rolling door armor 68 leads downwardly into the infeed funnel 22 of the guide rail device 10.

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

(39) The rolling door armor 68 has a slightly negative feed angle relative to the guide rail 12 of the guide rail device 10.

(40) Thus, the rolling door armor 68 does not hang exactly vertically downward because the guide rail 12 of the guide rail device 10 is not aligned tangentially to the bale 72.

(41) This can also be seen in the enlarged view of the guide rail device 10 of FIG. 4. The lines drawn indicate the orientation of the vertical guide rail 12 and the rolling door armor 68, and include a slightly negative angle.

(42) Since the connecting element is elastic, the connecting element is elastically bent as a result of the negative feed angle of the rolling door armor 68.

(43) Accordingly, the infeed funnel 22 adjusts to the negative angle and inclines in the direction of the right side in FIG. 3 and FIG. 4, i.e., for example, in the direction of the outer space of a building opening to be closed.

(44) FIG. 5 shows, in analogy to FIG. 3, a side view of the rolling door 11, with the rolling door armor 68 unwound from the winding shaft 70. Now the winding shaft 70 is also visible.

(45) Accordingly, the bale 72 is now empty.

(46) The end of the rolling door armor 68 now enters the guide device 10 at a positive feed angle relative to the guide rail 12, since the guide rail device 10 is not positioned exactly tangentially below the winding shaft 70.

(47) The connecting element is elastically bent by the positive feed angle of the rolling door armor 68, here to the left side in FIG. 5.

(48) Finally, FIG. 6 shows an enlarged view of the guide rail device 10 of FIG. 5. Again, the lines drawn indicate the orientation of the rolling door armor 68 relative to the vertical guide rail 12.

(49) The infeed funnel 22 now adjusts to the positive angle and also leans to the left side in FIGS. 5 and 6.

(50) When the rolling door 11 is moved, the infeed funnel 22 is movable.

(51) The sliding profiles 58, i.e. the rail leg sliding profiles 60, 62 and the funnel element sliding profiles 64, 66, enable the rolling door armor 68 to slide along the guide rail device 10 with low friction.

(52) During travel, the rolling door armor 68 passes the connecting element through the opening 54 and slides therein on the extended rail leg sliding profiles 60, 62.

(53) The infeed funnel 22 always adjusts to the current infeed angle of the rolling door armor 68 relative to the guide rail 12 of the guide rail device 10 during travel of the rolling door armor 68.

(54) The flexible infeed funnel 22 thus also adjusts to the acting forces and absorbs a part of the lateral acting forces of the rolling door armor 68.

(55) This results in low-noise operation of the rolling door 11.

(56) Furthermore, wear on the rolling door armor 68 and on the infeed funnel 22 or the funnel element slide profiles 64, 66 is reduced.

(57) To dampen vibrations and shocks of the movable infeed funnel 22, the guide rail device 10 also has a damping body 46.

(58) Thus, another advantage of the invention is that vibrations and shocks of the infeed funnel 22 are dampened by the damping body 46 connected to the infeed funnel 22 each time the rolling door armor 68 is deflected.

(59) This dampens or prevents the transition of noise from the infeed funnel 22 to the guide rail 12.

(60) In addition, the rolling door armor 68 is prevented from jolting during travel of the rolling door armor 68 in that region between the winding shaft 70 and the guide rail 10 attached to the building opening to be closed, where the rolling door armor 68 may move laterally due to the varying diameter of the bale 72 and the movable infeed funnel 22.

(61) One embodiment of the invention has been described above with reference to rolling doors. For more detailed configurations of possible embodiments of such rolling doors and also of rolling grilles, reference is made to the company publication [1] referred to at the beginning.

(62) The invention is particularly suitable for industrial doors.
