Abstract

Each vertically adjustable panel (2a-2n) has a guide portion (5) arranged on a guide (7), and a support (6) on another guide (8). The panels are separable from each other through outer lifting rolls (15) on an outer lifting guide (9). Each panel is provided on the lower part with a groove (3) and on the upper part with a spring (4).

Description

The invention relates to a sectional door with a plurality of vertically displaceable panels for closing a building opening, wherein each panel is mounted with at least one guide part on a first guide and at least one support member on a second guide.

Vertically movable gates for closing building openings are known to the skilled person in various embodiments. They consist essentially of a plurality of identically constructed panels or roller shutter elements (slats), which are mounted on a vertically extending portion of guides, preferably on both sides. To open and close such gates is usually an electric motor drive which acts via a traction means such as a chain, a belt or a belt on the bottom panel and the Opening the gate whose elements pull up.
In the open state of a door, the slats are wound into a tank around a winding shaft or the panels are guided on substantially horizontally oriented portions of the guides on or in the building opening on top, so that the panels hanging or lying under the ceiling - in a parking position - are arranged.

A disadvantage here is to be considered that for winding the slats to a tank these can be designed only with a small height or width and that for moving the panels in the horizontal direction - along the ceiling - a space requirement corresponding to the size (height) of the door necessary is.

Such goals are described inter alia in the DE 41 15 541 A1 as well as the DE 29 39 834 A1 in which a vertical gate is disclosed in each case from a plurality of coupled panels.

Such sectional doors also have the disadvantage that the coupling or articulated connection of adjacent panels with each other requires considerable design effort and these movable connections are susceptible to mechanical defects.

From the DE 26 23 359 B2 In addition, a closure device for wall openings or the like is known, which has a plurality of similar lamellae, which are guided in guide rails, arranged one another in a lowered state form a closed surface and in the open state by means arranged in the moving region of the lamella deflection above the wall opening or the like in vertical Able to be stacked side by side.
On both sides of the slats rotatably supported rollers are provided about an axis parallel to the longitudinal axis of each slat axis, wherein adjacent slats are interconnected by means of joints which are pivotable on the one slat about the axis of the rollers and slidable on the other slat parallel to the axis of the guide rails are attached. They still have a projection which is in each case displaceable by a roller of the deflection device so that the joint is pivoted about one of its ends, for which the joint having the shape of a plate at the same time has the shape of a rocking lever.

The advantage here is that the slats / panels hang in the upper horizontally oriented portion of the device, colloquially also called the parking area, arranged substantially vertically and parallel to each other spaced, so that the longitudinally extending space requirements compared to the aforementioned devices is lower. However, this structural design has the disadvantage that the movement speed for the opening or closing of the door limits are set. With this closure device, however, an opening speed of greater than 0.3 m / s is not possible; in particular at said gates whose panels are wider than 3 m.

Based on this prior art, the skilled artisan task is to improve a vertical sectional gate to the effect that a fast movement for opening or closing is guaranteed, mechanical damage can be avoided and the sectional gate after opening only little storage space for requires the parking of the panels.

According to the invention the object is achieved by a sectional gate with the features of claim 1.

The essence of the invention is that in a known vertical sectional gate, with individual substantially similar constructed panels that are not hinged together along their top and bottom longitudinal edges and thus temporarily separated from each other, the lifting of adjacent panels from each other, for the transition from the vertical movement into a horizontal movement, for the so-called parking of the panels above the wall opening in the horizontal section of the sectional gate, not with the known in one of the two guides mounted and guided, attacking the lamellas or panels, supporting parts takes place, but - in a new way and in contrast to the prior art - said lifting takes place by means of a hingedly connected to the respective upper panel Aushebeteil and a Aushebeführung. Preferably, the Aushebeteil is only temporarily stored during the movement of the panels when opening or closing the sectional gate in the Aushebeführung.

Thus, it is possible, in particular when opening the sectional gate, ie when its panels are moved in a conventional manner, preferably electric motor, up, the individual panels much faster than in known Moving devices, at least at a speed greater than 0.3 m / s.
The advantage of the invention is therefore that, in a substantially upright arrangement of the separate panels in the open state of the sectional gate in addition to the significantly reduced space requirement a very fast opening and closing is possible. The dimensions of the panels can also be made larger, ie each panel is higher than in panels wound into a shell / lamellae. In addition, the susceptibility of the sectional gate is significantly reduced by the absence of mechanical connections on the horizontal longitudinal edges between adjacent panels.

Preferably, the Aushebeteil each panel for the purpose of friction and noise reduction at least one Ausheberolle, which is guided when opening the sectional gate on said Aushebeführung.

The Aushebeführung is preferably arranged on both sides in the upper part of the sectional gate. Preferably, as seen in vertical alignment, between the first and the second guide, in particular in the region in which the vertical Pass sections of the guides in a curved portion through which the vertical and horizontal sections of the guides are connected to each other to continuous guides, and preferably extend into the substantially horizontally oriented portion of the sectional gate, but not necessarily over the entire length of latter section.

In this case, the guide means for the individual panels can be configured in any desired manner, but preferably as described below.

Further embodiments of the invention are the subject of dependent claims.

In order to obtain in the closed state of the sectional door a mechanically very stable and detachable connection between adjacent panels and to ensure adequate sealing of the sectional gate is proposed that the panels each top or bottom with a groove or a corresponding spring are provided. It engages in the closed state of the sectional gate, a top-side spring, which at an upper edge of a panel is formed, in a corresponding groove on the lower longitudinal edge of the overlying panel a. With such a groove and spring connection is also ensured that the individual panels can be solved in a simple manner from each other. Of course, tongue and groove can also be arranged vice versa.

The - when opening - for separating the adjacent panels from each other, each panel associated, preferably arranged on both sides Aushebeteile, preferably Ausheberollen, are each connected via two support arms with the respective guide part of adjacent panels. In this case, the support arms, for example rods made of metal, each movably connected to the Aushebeteilen and with the guide parts of the adjacent panels. If, when lifting the sectional gate, the outfeed rollers of a panel are guided over the removal guide in a predetermined path, the panel is lifted from the panel underneath, which is still raised substantially vertically upwards, whereby the support arms move relative to the panel To move the guide parts and the Ausheberolle so that the panels can be arranged in a row next to each other.

During the first guide, in the horizontal section of the sectional gate, the upper guide, and the second guide, in the horizontal section of the sectional gate, the lower guide, in conjunction with the guide member and the support member of the respective panel, substantially a vertically oriented position generate for the parking of each panel is by the new structural design of the connection of two adjacent panels, each with a hinged to the guide member support arm, which attack with its other end together movable on the Aushebeteil, the distance from panel to panel in parked position.

By said lifting of the respective upper panels of the underlying panels in the region of the transition from the vertical to the horizontal direction of movement when opening, ie in the upper region of the building opening, by means of said means for lifting, the relatively constant movement speed in each movement section during enable and ensure the opening and closing, this sectional gate is particularly excellent for use as a so-called high-speed gate.

The nature of the sectional door is proposed that the panels are made of metal and / or plastic, in particular aluminum, and in the form of injection molded, thermoformed or drawn parts are formed. In addition, in one or more panels and transparent sections, preferably made of plastic, be formed in order to brighten an interior of a building can.
To improve the thermal insulation of the sectional gate, it is proposed that seals, for example in the form of rubber lips, be arranged on the panels or the grooves and springs, in order to reduce the air circulation through the sectional gate.

The support members, which are assigned on the bottom side to each panel preferably on both sides, are preferably connected to the bottom edges of the panels with substantially horizontal struts so as to obtain a spacing between the first and second guides. The struts are designed for example in the form of metal rods.

To design the guides and the associated guide and support parts is proposed that these are each preferably designed as rails and rollers to the Opening and closing the sectional door as possible to perform resistance without resistance. In principle, however, all other types of guide devices which are known to the person skilled in the art can also be used.

To increase the passive safety of the sectional gate is proposed that this has a contact switch or a contact strip, preferably at the lower edge of the lowermost panel. Should a person or a vehicle pass through the sectional gate during the closing process and the lower edge of the sectional gate touch the person or the vehicle, this is detected via a known pressure switch or an optical switch and the sectional gate immediately stopped and again raised.

Details of Aushebeführung shown in Figure 1.

In the embodiment shown in Figure 1 is a vertical sectional gate 1 with a building opening 16 can be closed. For this purpose, the sectional door 1 is arranged on both sides of the building opening 16 on a wall 18 of the building such that the building opening 16 can be closed or opened with panels 2a,... 2n that can be moved in a vertical direction, as indicated by the double arrow 20 , For this purpose, the sectional door 1 consists of a plurality of panels 2a, 2b, 2c, ... 2n, which are of substantially similar construction; the inside has the reference numeral 2 ".
Each of the panels 2a, ... 2n is guided on both sides via a guide member 5 in the region of the upper edge of its end faces on a first guide 7, so that when opening and closing of the sectional gate 1, the guide member 5 is moved along the path of the guide 7 , In the same way, each panel 2a,... 2n is guided on both sides with a respective support member 6 arranged at the bottom on a second guide 8, so that each panel 2a,... N follows a prescribed path. The support member 6 is for this purpose on a horizontal strut 6a spaced from the inside 2 "of the panel to obtain an offset of the two guides 7, 8.

In the region of the wall opening 16, the guides 7 and 8 are guided vertically with their sections 7v and 8v substantially parallel to one another and then pass above the wall opening 16, each with a curved section 7k, 8k into a substantially horizontally guided section 7h , 8h over.
In this horizontal region of the sectional gate 1, the guide sections 7h, 8h are arranged in vertical alignment at a distance which, with respect to the distance between the guide part 5 and the support part 6 of the panels 2a, User of a new sectional door is selected. If the substantially vertical orientation of the panels in the parking position tend more to an inclination, so said distance between the two guide portions 7h, 8h will be less than the distance between the guide member and the support member. If the position of the parked panels is to be steeper according to another user-defined specification, the distance between the guide sections 7h, 8h will approach the distance between the guide part 5 and the support part 6 or max. be equal.

Each panel 2a,... 2n is provided at the top and at the bottom with a groove 3 and a correspondingly shaped spring 4, which in the closed state of the sectional door 1 engage flush with one another, as can be seen on the panels 2a, 2b.

To open and close the sectional gate 1 is a known drive unit with an electric motor 10 which drives a drive roller 11, as indicated by the double arrow 19, wherein on the drive roller 11, a flexible traction means 12, such as a rope or a belt, can be wound up and unwound, and the traction means 12 engages the bottom panel 2a of the sectional gate 1 on the bottom side via a fastening means 13. The drive unit is associated with a control unit (not shown).

Each panel 2a, ... 2n is additionally on both sides a Aushebeteil, here in execution as Ausheberolle 15 assigned, which can be performed in the upper part of the sectional gate 1 on a Aushebeführung 9, so as to separate, for example, the panel 2c from the panel 2b and to move substantially in a horizontal direction, so that the laid down in substantially upright position panels 2a, ... 2n can be arranged to save space under the ceiling 17.

For this purpose, each Aushebeteil, here the Ausheberolle 15, about in itself rigid support arms 14a, 14b and 14m, 14n each rotatably connected to the guide members 5 of two adjacent panels, for example, 2n, 2d and 2b, 2a connected. Each lifting member 15 and each pair of support arms 14a, 14b; ...; 14m, 14n form a circular component, which is superficially a lifting part, but also connects adjacent panels with each other.

The corresponding shape or the course of the Aushebeführung 9, which is preferably arranged on both sides of the sectional gate 1, the skilled person depending on the dimensioning of the panels 2, ... 2n and the shape of the guides 7, 8 possible.

With such a sectional door 1, the panels 2 a, 2 n can be stored space-saving under the ceiling 17 at a building opening 16, be moved very quickly, with an opening or closing speed of more than 0.3 m / s, wherein the sectional gate 1 is not susceptible to mechanical damage.

According to the embodiment shown in FIG. 1, the length of the two support arms 14a, 14b, ..., 14n, 14n, with which adjacent panels 2n, 2d,... 2b, 2a are interconnected with the interposition of the lifting member 15, So each pair of support arms in terms of amount always the same.
If within a sectional gate 1 but z. B. the height of the panels used 2a, ... 2n from each other is different - no matter for what reasons, eg. B because of a viewing window or the like in one or more of the panels - the length of the two support arms of the affected pair may differ in amount from that of the other pairs of support arms.

Basically, the design of the new components of the proposed new sectional door 1 is such that an opening angle α between the support arms of each pair of support arms 14a, 14b, ..., 14n, 14n is an obtuse angle in the vertical region of the sectional door 1 in the horizontal region of the sectional gate 1 is essentially an acute angle, at most a right angle.

In the figure 2 is in a sectional view taken along the section line 2-2 in Figure 1 one of the sides of the sectional gate. 1 shown. In the figure, the viewing direction of the observer, seen from the bottom upwards, goes from the inside of the building to the outside, so that in this figure the left area of the new sectional gate 1 is shown. Left of the building opening 16, the parts of the guide are arranged on the wall 18. The first guide 7, here its vertical section 7v, is arranged in alignment with the surface plane formed by the panels 2a,... 2n in the closed state in the region of the wall. Spaced to this surface plane of the panels 2a, ... 2n, so directed into the space inside, the vertical portion 8v of the second guide 8 is provided. In the embodiment shown, the parts of the guides 7 and 8, which face the respective other guide, are used together, whereby the constructional expenditure is reduced.
The panels 2a, ... 2n, here in the figure, the panel 2b are stored and guided with their respective top guide member 5 in the vertical portion 7v of the first guide. The lower portion of these panels, shown here on the panel 2b, is connected to the struts 6a with the support part 6, which is supported and guided in the vertical portion 8v of the second guide.
In this plan view is also the location of the Aushebeteiles, here the Ausheberolle 15 with respect to the first 7v and the second 8v guide apparent. This Aushebeteil 15 is movably connected to the support arm 14m, which is here made in two parts, with the guide part 5 of the panel 2b. The Aushebeteil 15 is also connected to the support arm 14n, 14n down to the guide portion 5 of the panel 2b below the vertically arranged panel 2a and is hinged to the guide member movable. This panel 2a is not visible here because of the representation in plan view, but in Figure 1.
In the vertical plane of the support arm 14n, the support arm 14f cut through the cut to this figure is then also indicated graphically, which is guided from the guide part 5 of the panel 2b to the lifting part 15 of the panel 2c above it, see FIG. For the sake of clarity in the illustration in Figure 2, the connection of one end of the support arm 14f with the guide member 5 of the panel to be seen 2b is not shown.
Shown is still the position of the spring 4 on the upper longitudinal side of the panel 2b.

Details of the lifting guide 9 shown in FIG. 1 are shown in FIG. In analogy to the sectional structure of the first guide 7 and the second guide 8 is also the Aushebeführung 9 - at least thoughtfully - in a vertically directed portion 9v, a curved portion 9k and a substantially horizontally directed portion 9h divided. The Aushebeführung 9 is disposed above the curved portion 8k and the horizontal portion 8h of the second guide 8.
On the representation of the first, in the illustrated section of the sectional gate 1, the upper guide was omitted here, since their position relative to the second guide 8 and the Aushebeführung 9 already in the figure 1 can be seen.
In order to avoid possible accidents, a securing rail 21 is arranged preventively above the lifting guide 9, which is also conceptually divided into a vertical section 21 v, a curved section 21 k and a horizontal section 21 h. The distance and the edge guide of the vertical portions 9v and 21v is selected so that the lifting portion 15 during the upward movement of the panels 2a, ... 2n has a smooth start and stop on the Aushebeführung 9, that is, the edges or facing each other Surfaces of these sections are arranged forming a funnel. In the curved portion 9k, 21k is the distance of the edges or the facing surfaces Both components substantially uniform. Towards the outlet of the horizontal section 9 h, 21 h, the channel opens, wherein in the illustrated embodiment, the horizontal section 21 h of the securing rail 21 runs obliquely to form a funnel-shaped opening.
