Abstract

A sliding sectional door, e.g. an up and over garage door, has at least one panel and has the top and middle of the panel supported between curved tracks to guide the door into a horizontal access position. The improvement has the bottom edge of the door supported between vertical guides through the entire opening movement to the horizontal position, and without any rearwards displacement required for the bottom edge.

Description

TECHNICAL AREA

The invention relates to a door with lateral guide rail assemblies comprising vertical, curved and horizontal rail portions. An at least one-part (one-sectional) closing element closes a door opening and is provided with at least one or two guide elements per door side for guiding the closing element to the associated guide rail arrangements such that the peat foot, ie the lowermost region of the closing element, is guided in the vertical guide rail area only parallel to the rail. At least one of the door drive or Torgewichtsausgleich serving flexible pulling means acts on or near the peat foot.

BACKGROUND OF THE INVENTION

The above-described sectional doors for closing larger door openings, such as garages, workshops or sports arenas have in many areas compared to roller doors, in which the closing element is wound up, but also against swing gates, in which the peat when opening outwardly pivots outwards, interspersed because they comparatively are stable and simple and yet neither the space for a winding drum, as required for roller shutter doors, need, even to the outside (ie in front of the gate) movement space when opening and closing need, as is the case with the swing gates. Meanwhile, the comparatively space-saving sectional doors are also available in installation situations with minimal space behind the closed door opening, such as from the WO 03/087504 known. In sectional doors that require little ceiling space, the curved rail portion of the guide rail assembly is located in an upper height portion of the door opening. In order to keep the free passage height as large as possible when the door is fully open, it is therefore necessary to move the locking element consisting of at least one section relatively far behind the door opening, so that the lowest section is also pivoted substantially into a horizontal position, the peat foot that is about the same height as the upper edge of the closing element forming Torkopf is raised.

PRESENTATION OF THE INVENTION

Against this background, the invention is intended to solve the problem of avoiding as far as possible the gates of the type mentioned wide displacement of Verschließelementes for complete gate opening. In addition, it is desirable, if possible, to allow for a minimal door construction and the safest possible operation a minimum space requirement of the door in the open state. These and other objects are achieved by a gate having the features of claim 1. Accordingly, there is provided a novel guide means for vertically lifting the peat foot in the height portion of the curved guide rail portion becomes. The gate does not need to be moved as far as in known sectional doors when opening (backwards) so as to nevertheless achieve a total horizontal position of the closing element. As a result, aesthetic aspects can be taken into account in a simple manner, since a comparatively inconspicuous drive and guide technology can be used. The invention can now be realized in a number of advantageous variants:

According to a first aspect of the invention (Figures 2, 6), the peat guide means is realized such that the curved rail portion is open on its radially outer side and provided with a vertical guide portion forming a gusset portion with each other. Thereby, a guide element associated with the peat foot, such as a known guide roller, of the closing element becomes possible to move vertically also in the height portion of the curved guide rail area, while the higher guide elements of the closing element can follow the curved guide surface of the curved rail area. Depending on the type of drive of the door and the design of an optional weight compensation device, the guidance of the door head takes place on the side facing away from the vertical guide section:

In order to enable the further guiding of the Torkopfes even after its pivoting from a closed position to a pivot position, an upper guide member is connected on each door side with the closing element. This may be an arrangement of the upper guide element located immediately near the door head (FIG. 2), wherein this guide element does not assume any guiding task during the pivoting process and is displaced in the interstice area between the vertical and curved guide rail section until it engages the curved guide section in FIG its uppermost area or already close to or on the horizontal rail area comes to rest and carries the weight on Torkopf. Also, the opposite (facing Toraußenseite) side of this upper guide element can be advantageous be used, namely form a torkopfseitigen stop when reaching the vertical position of the VerschGeßelementes. It is particularly advantageous if the counter-stop is formed by the vertical rail section. One or both of the pairs of stops can be adjustable for fine adjustment. In the horizontal rail area of this upper guide element also counteracts an upward force, the z. B. may occur when a cover-side door drive, in particular in conjunction with a push rod or a Wickeiwellenantrieb between a drive rail and the Torkopf is provided, as is common in many cases. Thus, while the curved rail portion has a varying distance between the inner and outer guide stops along the arc, the vertical and horizontal loop portions are preferably provided with parallel guide surfaces in a manner known per se to provide both inward and outward directions or to serve as a guide surface both in the upward and in the downward direction.

The upper guide elements can also be arranged in a manner known per se at the free end of each pivot lever (Fig. 6), wherein the other pivot lever end or a pivot joint is pivotally mounted on the Verschüeßelement, and wherein the storage in the case of mehrgliedriger closing elements the uppermost closing element takes place. Such pivoting levers can be equipped with (FIG. 6) and without (FIG. 1) forced adjustment. Examples of the former kind are in the German Utility Model Application No. 20 2005 008027 described. Examples of the second kind are in the WO 03/087504 , described. If such a pivot lever is provided, the guide element attached thereto is guided along the curved rail area. During the pivoting between the vertical closed position and a pivoting position of the uppermost door section, the Torkopf approaches the upper guide element when the pivot joint 10A is provided below the Torkopfes on the upper door section. However, the pivot joint can also be provided at or near the Torkopfes when a pivot angle limit at approximately horizontal opening position of the upper door section prevents the lowering of the Torkopfes. A pivot angle limiting stop is also in other designs and arrangement of the pivot lever beneficial.

Alternatively, in this first aspect of the invention, a switch (preferably FIG. 1), which is preferably automatically activated, may be provided in the interstice area between the vertical guide section and the bent guide section, which preferably runs bent or angled and has guide sections on two sides one facing the curved and the other facing the vertical guide rail section. In particular, such. Soft be designed as a two-armed lever and its pivoting in one direction by a near the peat guide element of the closing element are effected and in the opposite direction of a higher-level guide element closing element are reversed. As a result, the guide elements close to the peat foot follow the vertical guide section 5A and the higher guide elements follow the horizontal guide section 5B. Further guide elements preferably remain on one side of the switch and are therefore inactive for the switch adjustment.

In these and other embodiments of the invention, a traction means, such as a rope engaging near or at the peat foot, is deflected near the upper gate opening.

According to a further aspect of the invention, the pivoting of the at least one closing element during the closing process is effected by a stop arrangement (FIGS. 1, 4) provided in the lower end region of the closing element to be pivoted. As a result, a small vertical movement of the (uppermost) closing element to be pivoted leads to a relatively large pivoting angle, so that the door head can be pivoted into a closing position even with relatively small gap dimensions, without any significant height change of the door head taking place. This embodiment is also independent of the features of claim 1 of independent inventive importance.

According to the still further aspect of the invention (Fig. 3; 5) it is provided that a guide element close to the peat foot is provided on a lower pivot lever such that this guide element enters the curved guide rail area when the peat foot is opened from one vertical to the other approximately horizontal opening position is pivoted high, wherein the (lower) closure element hinged via a pivot means pivot lever changes its pivot angle with respect to the closure element in this opening phase. This arrangement is used in a variant embodiment (FIG. 3 b) as guide means, with which the peat foot is raised or guided essentially vertically in the height section of the curved guide rail area. In this solution, it is possible to dispense with a guide rail section extending vertically in the upper door region. If this makes the peat foot in the last phase of the opening movement passes through a slightly different from the vertical direction of movement curve, this is harmless, because persons or objects in this height portion of the door opening are usually not encountered and these movements of the peat to the inside or outside only relatively minor Nature are. In this aspect of the invention, a vertical upper guide rail section may additionally be provided, in which a guide element arranged directly on the peat foot in addition to the pivot lever can be guided.

According to a still further aspect of the invention (Fig. 1, 3-6), a deflection means for the flexible traction means connected to the Torfuß is provided on the uppermost closing element such that upon pivoting of the at least upper closing element in the vertical closing position, the traction means deflected in the pivoting direction becomes. During the subsequent door opening by applying a tensile force on the traction means the previous Zugmittelauslenkung acts as a lateral force which pivots the uppermost closing element at the vertical closing position in a pivot position in the sense of a power drive without further force effects in the opening direction are required on Torkopf. According to this aspect of the invention, an above-mentioned and known per se upper pivot lever with end-side guide element is preferably used, wherein the articulation region of this lever to the closing element for the Zugmittelauslenkung can be used. Once the induced by the Zugmittelauslenkung transverse force has ceased to act, because the deflection is reduced to zero, other lateral forces can be used for further pivoting of the Torkopfes. Gravity can be used for this purpose. Likewise, forced guides or corresponding automatic actuators or the like are used for this purpose. The Zugmittelumlenkung this aspect of the invention is also independent of the features of claim 1 of independent inventive importance.

According to a still further aspect of the invention (Figs 3a, 4, 5), as a guide means, with which the peat foot in the height portion of the curved guide rail area is vertically raised, a substantially gate-high vertical guide rail is provided, so that the peat foot as a roller shutter door only moved vertically over the entire door height. This also minimizes the footprint of the open door. The combination of a gate-high vertical guide rail with a horizontal guide rail followed by a bow area and subsequent vertical guide rail area, which does not necessarily have to extend to the lower edge of the door opening, is independent of the features of claim 1 of independent inventive importance.

A still further aspect of the invention consists in a closure element consisting of two sections (Fig. 3a; 3b), so that even large gates, in particular comparatively high gates, can be constructed extremely simply and the lower section can be used for the installation of passage doors. These can even be executed without a threshold. When these doors are closed, they form a unit with the remaining part of the lower door section, which can be lifted altogether and pivoted into a high horizontal opening position. For outward opening doors not even a door lock is absolutely necessary for this. This aspect of the invention is independent of the feature of claim 1 of independent inventive importance.

It is important to note that the features of the various aspects of the invention may also be used in combination with one another, particularly in combination with other embodiments of the invention, so as to achieve a wide variety of applications of the invention.

The abovementioned and the claimed components to be used according to the invention described in the exemplary embodiments are not subject to any special exceptional conditions in terms of their size, shape design, material selection and technical design, so that the selection criteria known in the field of application can be used without restriction.

Further details, features and advantages of the subject matter of the invention will become apparent from the subclaims and from the following description of the accompanying drawings, in which - exemplary embodiments - preferred embodiments of the inventive arrangement of a gate are shown.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The sequence of Figure 1 shows a two-part sectional door 10 having a lower section 10A and an upper section 10B. On both sides of the door is a guide rail assembly consisting of a vertical guide rail portion 7A, to which a curved rail portion 7B and this in turn is followed by a horizontal rail portion 7C. The gate has at its Torfuß 2 a guide element 2A in the form of a guide roller on each side, which runs in opening and closing of the door in the guide rail assembly 7. In the joint area between the two Torblattsektionen another guide element 3 is arranged in the form of a tandem guide roller, which also runs in the guide rail assembly 7. An upper guide member 4 in the form of a guide roller is provided on the upper section member (closing member 10B). It is located at the free end of a pivot lever 100, which is arranged vertically pivotable on each door side via a pivot joint 100A. A traction means 15 in the form of a steel wire rope engages the peat foot 2 and is deflected by a deflection roller 16 near the upper door opening to a drive, not shown. - In that regard, the arrangement is known.

The curved rail portion 7B is formed triangular or gore-shaped and has a curved radial outer side 7B 'as a guide roller bearing surface for the Guide elements 3 and 4 on. The gusset portion further comprises a vertical guide portion 7B "serving as a guide for the gate-side guide member 2A, In the gusset portion 6, a switch 5 having a substantially vertical guide portion 5A and having an approximately horizontal guide portion 5B is pivotally arranged about a horizontal axis. This switch is arranged in the closed position (FIG. 1A) in an obliquely downwardly pointing position and shaped so that the central door guide element 3 can enter the gate area when opening the gate and abuts the approximately horizontal guide section 5A from below, and the switch 1C, the switch opens in the direction of the horizontal guide rail area, in this switch position the gate-side guide element 2A on the switch outer side is able to move further towards the door until it has arrived in the upper end position shown in Figure 1 D with the door fully open. When Torschließen the process of automatic Weichenverstellung runs in the reverse direction, the switch adjustment is in turn caused by the middle guide element 3.

FIG. 1 also shows a stop arrangement 12, 12A, 12B which, when closing the door, causes the door section 12B to be forcibly pivoted from the tilting position shown in FIG. 1B to the closed position shown in FIG. 1A. For this purpose, a pivot arm 12A is attached to the upper end portion of the upper door section 10B at this and comes with the beginning of Zwangsschließweges with a torrahmenfesten bolt as a stop 12B in Appendix. Another Torsenken thereby leads to Zwangsverschwenkung the upper door section in the vertical closed position.

In addition, Figure 1 shows an automatic power drive for tilting the upper door section 10B from the closed position to the tilted position. For this purpose, a deflection of the traction means 15 in the closed position is used. For this purpose, the deflecting roller 16 is arranged offset to the rear from the door opening to such an extent that the traction means 15 is deflected forwards when the door is closed (FIG. 1A). One serving for this deflection 13 is provided at or near the pivot joint 100A at each torrent and engages the traction means 15 automatically. Due to the gravity driven forced closing when closing the gate, the traction means is therefore deflected towards the door opening. Now, when the door opening the traction means 15 in a suitable manner (see below) wound or otherwise pulled backwards, it exerts on the deflection means 13 directed towards the Torinneren force, which leads to the inward pivoting of the upper door section 10B.

The gusset-like design of the bent rail portion 7B can also be seen in the embodiments of Figure 2 and Figure 6: The forced closure with the stop assembly 12 is also realized in the embodiment of Figure 4. The cable deflection for tipping the upper door section when opening is also realized in the embodiments according to FIGS. 3 b to 6.

In contrast to FIG. 1, FIG. 2 shows a conventional push rod drive 9 for opening and closing the door. For this purpose, a known drive rail 9B, the z. B. tormittig on the ceiling or in the upper space z. B. a garage is attached and a push rod 9A can move back and forth, the remote end of the push rod acts approximately in the area of the Torkopfes 8. Here, a special simple gate opening and door closing and tipping over and tilting of the upper door section is made possible without further aids while still standing on the ground peat foot. As weight compensation, a known torsion spring arrangement can be used, which helps to lift the peat 2 via a flexible traction means 15 and so relieves the door drive.

A push rod drive as in Figure 2 is also realized in the embodiment of FIG. 3a. The torsion spring assemblies for weight balance in Figures 2 and 3a can also be replaced by a horizontal Zugfederanordnung, as shown there by way of example.

Figure 3a / b shows the peculiarity of a lower pivoting lever 20, the, with the door closed towards the rear bottom pointing to the lower door section 10B is pivotally attached to each torrent and at its free end a guide element 20A 'in the form of a guide roller which moves in the continuous guide rail 7 instead of the guide element 2A from the other embodiments. This eliminates, inter alia, a forced operation peat nut 2. When the door is open, the lower pivot lever 20 is pivoted away from the door section 10B down obliquely.

Fig. 3b shows an embodiment of this gate, with a winding drive. For this purpose, a drive motor 19 is fixedly disposed under the ceiling, which can pull the traction cable 15 and on.

FIG. 4 shows a further embodiment in which a vertical guide rail 14 near the door opening occupies approximately the entire available height and vertically guides the peat foot via its guide element 2A over the entire opening path. Behind the vertical rail area 7A ', a second guide rail is arranged with a vertical area 7A, an arc area 7B and a horizontal area 7C, wherein the vertical area does not have to be led to the floor. The middle and upper guide elements 3 and 4 are guided in the latter guide rail.

Figures 4E and 4F show passage doors 18 installed in the lower closing element 10A. With a corresponding door opening height and only a few, in particular two, door sections, therefore, the through doors 18 are limited solely to the lower closure element 10A, which constitutes a frame in which one or more of the passage doors 18 are held pivotable about vertical axes. In that regard, Figure 4F shows four such doors in the form of two double doors, which can open almost the entire gate width as a passage area with otherwise closed gate.

FIG. 5 shows a variant of the two-rail arrangement of FIG. 4, in which the rear guide rail is also guided to the ground in its vertical area is. In addition, the embodiment has a lower pivot lever 20, as shown and explained in connection with Figure 3a / b.

FIG. 6 shows, in a modification of the embodiment according to FIG. 2, a traction cable drive as also shown in connection with FIGS. 1, 4 and 5. The peculiarity of this embodiment consists in a device 11 for forced adjustment of the upper closing element 10B between the closed position (FIG. 6A) and the tilted position (FIG. 6B). Serves this purpose a power drive in the form of a pivoting drive, which is effective between the upper door section 10B and the pivot lever 100 to change the angle between the pivot lever 100 and the upper door section, thereby achieving a tilting of this door section between the two mentioned positions. Upon further opening, the pivoting lever 100 can be folded even closer to the upper closure element 10B, as shown in FIG. 6C. When closing the movement is reversed.
