Abstract

The device has a slide rail (18) attached in an area of a frame (2), and a door leaf formed from segments (10) that are arranged one after another. A covering unit (24) extends over the entire length of the segments in a moving direction of the leaf. The covering unit projects from a plane of the leaf towards an inner side of the door such that the covering unit covers the frame area in which a roller and the slide rail are provided. An independent claim is also included for a garage including an overhead sectional door.

Description

The present invention relates to a device for preventing a grasping between a door leaf and a Zargenbereich a sectional door by covering this area.

STATE OF THE ART

For gates for garages, halls or similar buildings is a relatively significant risk of relative movements between moving parts of the door leaf and fixed parts of the frame, objects or body parts, especially fingers, pinch, squeeze or shear. This danger is greater when motor drives are used to set the door in motion. In addition to the risk of accidents, it should also be noted that the ability of the door to be restricted as well as wear or damage can be promoted by jammed foreign objects.

In the case of the overhead doors or swing gates, it is known from DE 101 01 567 A1 of the applicant to provide a cover in a particularly vulnerable area of scissor-like moving components, wherein the surface extension of the cover opening or closing gaps between the relatively moving Parts of the door suspension and / or the door leaf during the entire opening or closing operation permanently covered.

It is also known from EP 1 325 998 A2 to provide certain areas of a lever mechanism and / or the spring assemblies of a tilting or pivoting door with a cover for accident protection. In particular, there is one Protective device for a tilting or pivoting element which can be moved in particular over the head for protective sealing and / or covering an intermediate or transitional area between two relatively movable sub-elements of the tilting or pivoting gate, in particular an intermediate region between the frame and the door leaf or between the frame and one Tilting or pivoting lever mechanism disclosed, which is characterized by at least one preferably of a first, rigid, unyielding and / or impact-insensitive material supporting or support member which is attachable to fix the protection device or a part thereof on one of the two sub-elements or with the same is connected, and by at least one Schutzleisten- or -lippenelement, which is mounted on the support or support member or one of a plurality of support or support members and designed relative to the support or support member so movable or yielding that it e Inem located in the transitional or intermediate area foreign body, in particular a hand or a finger of a person, in the course of a succession-to-move the sub-elements can dodge to reduce or prevent jamming or squeezing of the foreign body, the protective device as Cover is formed for a in the course of the door leaf movement of the frame approaching part of a pivoting or tilting lever mechanism or includes such.

In sectional doors, in particular overhead sectional doors, there is a comparatively large area in which fixed and movable parts perform relative movements relative to one another. These areas are usually easily accessible and therefore offer the possibility of hand and finger intervention, which can result in pinching, crushing or shearing injuries. or introducing other foreign bodies, which can lead to disruptions in the operation of the gate.

For the sake of illustration, reference is already made at this point to FIG. 1, which shows an overall view of a ceiling sectional door of the present invention, but which is also well suited for explaining the basic principle of a ceiling sectional door. Figure 1 is a schematic overall view of a ceiling sectional door seen from the inside, wherein only one (the left side viewed from the inside) is shown and the right side is broken away.

Between two attached to a wall piece 8 frames 2 (only the left seen from the inside is shown) is a door leaf 4, which is composed of a plurality of successively or superimposed segments 10 is constructed. The door leaf is mounted and guided by means of laterally arranged rollers 6 in rails 18. The segments 10 are further by means of hinges (not shown) to each other in the manner of a hinge pull pivotally. In the drawing, only indicated, describes the track above a bow to the inside of the gate and then runs (usually directly under the ceiling of the garage or similar) in almost horizontal direction on. A fixed to the ceiling motor 5 pulls on the top segment, thus setting the entire door leaf in motion. Further, a weight relief may be provided such that a rope received in a ceiling-mounted, spring-loaded pulley rope attaches to the lowermost segment (not shown in detail) and thus exerts an upward force on the entire door leaf.

The frame 2 with the running rail 18 and the rollers 6 guided therein is generally accessible. This creates the possibility of reaching into it or introducing foreign bodies, which could lead to injuries or malfunctions. Although this problem is particularly conspicuous in overhead sectional doors due to the floor-level rails, the above problem can also occur in principle with side-sectional doors, especially those of such low height that the running rail running under the ceiling is at gripping height.

The present invention has for its object to overcome the above-mentioned maladministration and to provide a way to limit the accessibility of the frame area, so as to avoid injury and malfunction.

SUMMARY OF THE INVENTION

The object is achieved by a device according to claim 1, a sectional door according to claim 20, a garage according to claim 21 and a retrofit kit according to claim 22. Advantageous embodiments and further developments of the invention form the subject of the dependent claims.

According to the present invention, an apparatus for preventing an ingress between a door leaf and a Zargenbereich a sectional door with a frame, a mounted in the frame frame track and one of a plurality of successively arranged, mutually pivotable, guided by rollers or the like in the track rail Segments constructed door leaf, a pointing in the region of the frame side of at least one segment on this attached cover, which is substantially over the entire length of the segment in the direction of movement extends the door leaf and which protrudes from the plane of the door leaf to the inside of the door in such a way that it covers the frame portion of the door substantially.

By such a cover that protrudes from the plane of the door leaf to the inside of the door so that it covers the frame area in the closed position of the door substantially, the reaching into the frame area in which the running rail and the rollers running therein Tores are difficult. Since the cover is attached to the segment, it moves with the opening and closing of the gate with the segment and reliably covers always the area of the frame or the running rail, in which are just rolling and moving. Since the cover elements extend substantially over the entire length of the segment, the frame region is covered over the entire length of the segment, in the case of several segments provided with a cover element over the entire length of these segments. This reduces the risk of accidents of such a door and increases the functional and operational safety.

The cover may be a substantially flat planar component, which is in most cases the simplest and thus most cost effective construction of such an element.

The cover element is preferably fastened to a side wall of the segment facing the frame, but may also be fastened to the inner wall of the segment by means of a substantially perpendicular leg, wherein the first variant places the lower requirements on the geometric shape of the cover element, the second variant however, the ease of installation increased at already completed and built gates.

Alternatively, the cover member may be integrated into the side wall of the segment facing the frame. As a result, the total number of parts for the gate and thus the cost of manufacture, storage and assembly can be reduced.

The cover is preferably made of plastic. Plastic is a class of relatively inexpensive and lightweight materials that have very variable material properties and therefore can be selected according to the circumstances advantageous. They are easy to shape and can be dyed in any desired color.

The cover member may include a fixing member fixed to the segment and a working member made separately from the fixing member, which is fixed in or on the fixing member and serves the cover of the frame portion. In this case, at least the working part is preferably made of plastic. In such a two-part embodiment of the cover, the material properties can be selected even more targeted. The fixing member may be made of a hard material such as a thermoset, a hard rubber or a metal, while the working part is made of a more flexible material. In the event of damage to the working part, it can be replaced without having to replace the fastening part. As a result, on the one hand, the mounting of the entire cover element, which may be quite expensive, in particular when mounted on the side of the segment, can be avoided, making replacement easier and less expensive. On the other hand, the sometimes quite thin material of the side or inner wall of the Protected Segments, since repeated removal and installation operations omitted.

The compliance of the cover member in the region of its attachment to the segment may be less than in the region of the cover of the frame portion. By such a design external influences on the cover can be better cushioned and damage to the same avoided.

Adjacent end faces of the cover elements of two successive segments preferably each have a curvature which follows a cylinder surface about a pivot axis of the segments. The distance between a gap between the adjacent end faces of the two cover elements is preferably so small that a reaching through the gap is substantially impossible. In this way, the end faces of the cover can slide past each other during a pivotal movement of the segments relative to each other, without dislocating or touching. The small clearance makes penetration substantially impossible and thus prevents pinching and dragging of an object or body part with the gate moving.

The adjoining end faces of the cover elements of two successive segments are preferably provided with each other at least partially and at least in a pivoted state of the two segments overlapping profiles. This can be realized by having the complementary profiles have a lapping or a pair of comb and groove or a mutual offset. In the case that the end faces of the adjacent cover elements are curved in the manner described above, can by a overlapping execution of the profiles of the gap between successive cover elements are bridged, so that an on-reaching further difficult. The stability in profile transverse direction can be increased by such an overlap. In the event that the end faces of the adjoining cover elements are not curved in the manner described above, the pivoting of the segments can only be made possible with appropriate generous design of the profile recesses by the overlapping profile parts slide past each other laterally.

The frame of the door preferably has a termination portion which cooperates with the cover in the closed position of the door so that the cover rests substantially flat on the end portion at least at its edge. In this case, the end portion may be integrally formed with the frame or made separately from the frame and fastened by plugging or terminals or by means of fasteners on the frame, in the latter case, the frame may have a receiving portion for receiving the end portion, preferably so is formed so that the outer contours of the frame and the receiving portion form a plane.

With the help of such a final section, whether integrated into the frame or as a separate component, is formed in cooperation with the cover with the door closed a kind of closed box that completely surrounds the frame area. Thus, a gripping behind the cover and prevents the safety of the door can be further improved. If a receiving portion is provided in the above-mentioned manner that the outer contours of the frame and the receiving portion form a plane, even in confined spaces, For example, if the frame is attached directly to a side wall of the garage or the hall, the end portion attached to the frame.

In an alternative construction, the covering element has a surface part extending from the segment to the inside of the door and a transverse part adjoining the surface part and extending in the direction of the frame. With such a construction can be dispensed with attached to the frame or integrated in this final part. Preferably, adjacent end faces of the cover elements of two successive segments each have a curvature which follows a cylinder surface about the pivot axis of the segments. The cover element may have rib parts which protrude at right angles in the direction of the frame from the surface part and in each case follow the upper and lower end side of the cover. The cover is preferably made of plastic.

Preferably, when the door is closed at the maximum gripping height of a human lying segments are provided with a cover, but it can also be provided with a cover member all segments. From the point of view of safety and economy, it is usually sufficient if the cover elements are provided only up to the maximum gripping height of a human (provided that the total height of the door leaf is greater than this maximum gripping height). For aesthetic reasons, however, it may also be desirable to equip all segments with such a cover element.

Further aspects of the invention are directed to a sectional door, in particular a ceiling sectional door, with a device of the present invention, to a Garage with such a gate and on a retrofit kit for a sectional door, in particular a Seitensektionaltor, with a cover and optionally a separate end portion, as described above, directed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

For the sake of clarity, FIG. 1 shows a schematic overall view of a ceiling sectional door viewed from the inside, wherein only one side (the left-hand side) is shown and the right-hand side is broken away. The basic mode of operation of a ceiling sectional door has already been explained in the introductory part of this description with reference to FIG. These statements are only referenced here. In the following embodiments and variants of the invention it is assumed that the gate is provided for closing a garage or the like.

Figure 2 shows the region of the frame 2 in enlarged form and in section. The section is taken along a line in Figure 1, the viewing direction points downward (arrow on line II-II). As seen in Figure 2, the section through the wall piece 8, the frame 6 and the running rail 18 mounted therein, in which one of the rollers 6 is visible from above, and further through a side wall 16 of the segments 10 and a short distance in this in, wherein also an outer wall 12 and an inner wall 14 of the segment 10 and a mounted on the frame seal 20 which rests from the outside on the outer wall 12 of the segment 10, are cut with. As a side wall 16 is here to be understood the final wall of the segment 10, which faces the frame 2, as the outer and inner walls 12, 14, the final wall of the segment 10, the interior of the closed space through the gate or facing is.

The basic principle of the present invention is shown schematically in FIG. Laterally on the side wall 16, a cover 24 is attached, which is a substantially flat planar component to the inside extends the gate and so the accident prone area of the frame 2 with the running rail 18 and the movable rollers 6 covered.

On the inside of the door, a U-shaped end cap 22 is attached to the frame 2, which offers the cover 24 a lateral contact surface. Due to the contact between the cover 24 and the end cap 22, the lateral area between the door leaf and the frame forms a closed box, which is not accessible from the inside of the door. When the door is opened, the cover 24 slides along the end cap 22. The closed area does not change as a result, so that it is not possible during the operation of the door to reach into the accident-prone area between the door leaf 4 and the frame 2.

The end cap may be glued or clamped to the frame 2, placed on it and / or attached to it with suitable fasteners. In the illustrated form, the frame 2 a cranked portion 21 which receives the end cap 22 so that a common outer surface is formed by the frame 2 and the end cap 22. This is advantageous if the frame is flush mounted on a side wall of the garage.

It is understood that, although all segments 10 may be equipped with a cover 24, it is sufficient to equip only the lower of the segments up to (maximum conceivable) gripping height in this way.

Regardless, it must be ensured that the covers 24, when the segments 10 when passing through the curved portion of the track rail 18 to each other be panned, do not collide with their upper and lower ends.

FIG. 3 shows a sectional view along a line III - III in FIG. 2 in the direction of the arrows indicated there, and represents a first embodiment of the present invention. In FIG. 3, two adjoining segments 10 can be seen. The upper one of the segments 10 is pivotable counterclockwise about an axis 26 connected to the lower one of the segments 10 and the lower one of the segments 10 towards the left side in Fig. 3, i.e. counterclockwise. The axis 26 is close to the inside of the segments 10, in the longitudinal direction (direction of movement of the gate) in the region of the lower of the segments 10. It should be noted that the axis in the transverse direction also in the interior of the segment 10 or further outside on the inside of the gate ( to the left of the segments 10 in FIG. 3).

The upper end of the lower of the segments 10 has a convex portion 28 in a conventional manner, while the lower end of the upper of the segments 10 has a concave portion 30. The lines of curvature of the concave portion 30 and the convex portion 28 follow concentric orbits about the axis 26. That is, the adjacent end faces of the segments 10 follow concentric cylinder surfaces about the axis 26. Thus, it is ensured that the upper and lower of the segments 10 at Pivoting about the axis 26 at all points of the adjacent sides always keep the same distance and slide along each other, without the segments gape or touch at any point apart.

Like the segments 10, the cover elements 24 each have a convex portion 32 (upper end of the lower of the cover member 24) and a concave portion 34 (lower end of the upper of the cover member 24). The curvature lines assume those of the segments 10 or continue. Optionally, the concave portion 34 has a shortened portion 36 formed by cutting off the outermost tip of the concave portion 34 to prevent it from entering the flank 38 of the lower cover portion 24. In this way, also slide the end faces of adjacent cover portions 24 at a constant distance along each other, without gapping at the pivoting of the segments 10 about the axis 26 or interfere with each other.

Figures 4A and 4B show two variants of the end faces of two adjacent cover elements 24 in a sectional view taken along a line IV-IV in Figure 3. The section is in a vertical plane parallel to the Torblattebene, the cover 24 are cut on the inside of the door , The view is directed from the inside of the room closed by the gate to the gate.

In the variant shown in Figure 4A, the lower (concave) end 34 of the upper of the cover members 24 and the upper (convex) end 32 of the lower of the cover 24 are blunt, so that there is always a defined gap between these ends.

In the variant shown in Figure 4B, the lower (concave) end 34 of the upper of the cover members 24 and the upper (convex) end 32 of the lower of the cover members 24 are profiled so as to overlap each other in the manner of overlapping. So there is no gap between these ends. With such a construction, a pinching of fingers or objects between the Covering additionally complicates and thereby further improves the accident and reliability of the so-equipped door.

In a further (not shown) variant, the lower (concave) end 34 of the upper of the cover 24 and the upper (convex) end 32 of the lower of the cover 24 are profiled so that they interlock in the manner of comb and groove. With such a construction can be reliably prevented that the adjoining cover 24 can not gape apart even when pressed sideways direction. Thus, intervention further complicates and the operational safety and accident protection of the gate can be further improved.

Although only the area is shown in the figures, in which two cover elements 24 meet each other, it should be understood that each of the cover 24 has a convex portion 34 at its upper end and a concave portion 32 at its lower end. It is understood, however, that the cover 24 of the bottom of the segments 10 may not have a concave portion at its lower end, otherwise its tip would touch the ground.

It is also understood that the conditions may be exactly the opposite as shown in Figure 3. That is, the axis 26 may be disposed in the respective upper one of the segments 10 with the result that the respective upper two adjacent segments 10 and cover 24 would each have a concave portion and the respective lower one convex portion.

FIGS. 5 to 7 show a second embodiment of the present invention. It corresponds 5 shows the view of Figure 3 of the first embodiment, ie, a section along the line III-III in Figure 2, but for reasons of clarity, the representation of the frame and the rail has been omitted. Figure 6 is a sectional view taken along the line VI-VI in Figure 5 in the direction of the arrows indicated there and thus corresponds to the view of Figures 4A and 4B. FIG. 7 corresponds to the view of FIG. 5 and shows the connection region of two adjoining segments 10 in the pivoted state.

In this embodiment, the end surfaces of both the segments 10 and the cover members 24 are formed at their respective upper and lower ends not concentric with the pivot axis 26, but substantially planar and perpendicular to the boundary surfaces on the inside and outside of the door. The axis 26 lies in the vertical center between two segments 10, in the horizontal direction on the inside of the gate (it can also be located further inside). In this construction, the edges on the outside of the door necessarily gap apart when the segments 10 are pivoted against each other.

In order to avoid a mutual obstruction of the adjacent end faces of the cover 24, the ends are formed in the manner of a Überblattung. That is, of each cover 24 is at the lower end facing the frame facing profile half notched (notch 42 of the top of the cover 24), while at the top of the facing away from the frame profile half is notched (notch 44 of the lower of the cover 24th ), so that the two left profile halves slide past each other upon pivoting of the respective segments 10, as shown in Figure 7. The upper end of the lower of the cover 24 is here extended upward in the form of a projection 46, so that the two cover members 24 in the non-pivoted state of the segments 10 in the region of the projection 46 laterally abut each other. Thus it can be prevented that the left half of the profile of the adjacent end faces of the cover 24 in any deformations hinder each other when the segments 10 are pivoted against each other.

The notches 42, 44 are each formed with an angle A which is adapted to the maximum occurring pivoting angle of the segments 10 (see the dimension "S" in FIG. 7) with respect to the longitudinal direction of the segment 10 or of the cover element 24, as in FIGS. 5 and 7 shown. That is, in this embodiment, A = 90 ° -S. In the figure, A = S = 45 ° is chosen for the sake of drawing simplicity, but there are - depending on the length of the segments 10 and the curvature of the track rail 18 - other angular relationships possible.

In the thickness direction of the segment 10, the notches 42, 44 begin substantially where the segments 10 stop. That is, in the region of the side walls 16 of the segments 10, the cover elements 24 are not unlatched. Thus, the cover 24 lie with the entire profile thickness on the side walls 16 of the segments 10.

Further, the notches 42, 44 are formed so that they extend up to a length X1 and X2 along the longitudinal direction of the cover 24, ie in the opening direction of the door and extend only from this length X1 and X2 with the angle A. The length X1 of the notch 42 at the lower end of the (upper) cover 24 is adapted so that the projection 46 of the lower of the cover 24 with its end face on the notched oblique face at the bottom of the (upper) cover 24 abuts when the segments are pivoted about the maximum pivot angle S against each other (see Figure 7). The length X2 of the notch 44 at the upper end of the (lower) cover member 24 is selected so that in the pivoted state of the segments 10 between the end face of the left lower end profile of the upper of the cover 24 and the notched oblique face at the upper end of ( lower) cover member 24 remains a gap distance G which is so large that a crushing of body parts, such as fingertips, between these end faces is not possible.

From the above description of this embodiment, it can be seen that the end surface of the projection 46 abuts against the end surface of the notch 42 when the segments 10 are pivoted about the pivot axis 26. Therefore, the side with the projection 46 must always face the frame 2 in order to avoid a risk of crushing. (Of course, this risk only exists if the area in which the segments 10 are pivoted because of the curvature of the running rail 18 is not out of the reach of a human.) This means that the two sides of a ceiling sectional door have different, namely a mirror image Cover elements 24 must be provided. However, this can be avoided if the distance X1 is also chosen so large that upon pivoting of the segments 10 between the end face of the projection 46 and the end face of the notch 42 also a sufficiently wide gap remains to be able to reliably exclude a risk of crushing can.

In contrast to the previous embodiment, where the cover 24 have a concave lower end face and the cover 24 of the lowest Segments 10 unlike any other has a straight bottom trained, have in the present embodiment, all segments 10 and all cover 24 substantially straight-trained bottoms and therefore can sit flat on the floor. Therefore, in the present embodiment, all the cover members 24 including those for the lowermost and uppermost of the segments 10 can be made the same; the slight projection of the uppermost cover member 24 through the projection 46 does not interfere with the weight. As a result, costs can be saved in the production, storage and installation, since only one type of cover elements 24 - if necessary in mirror-inverted version for the left and right side of the door - must be observed.

$$X2\ge \sqrt{Y^2+H^2}+G$$

erfüllt sein, wobei Y die Erstreckung der Abdeckelemente 24 auf der Innenseite der Segmente 10 ist, H die Höhe des Vorsprungs 46 ist und G ein minimal erforderlicher Spaltabstand ist, um eine Quetschgefahr mit ausreichender Sicherheit ausschließen zu können.After the swivel angle S of the segments 10 depends on various geometric conditions such as the length of the segments 10 and the curvature of the track rail 18, it may be that the notch angle A can not be adapted in advance to the swivel angle S. In a variant of the present embodiment shown in Figure 8, the notch is straight, ie, executed at an angle of A = 90 °. Thus, the cover 24 may be formed with respect to their notch regardless of the other conditions, in particular regardless of the length of the segments 10 and the curvature of the track rail 18. The length X1 or X2 of the notches 42, 44 should be selected so that even with maximum conceivable pivoting of the segments 10 no narrow gaps between the respective end faces arise, so that a risk of crushing between them can be reliably excluded. That means it should be the relationships $$X$$$$1\ge \sqrt{2}\times Y+\mathrm{<figure-callout\; id="2"\; label="G\; X"\; filenames="imgf0001.png,imgf0002.png"\; state="\{\{state\}\}">G\; </figure-callout>}$$

$$X$$$$2\ge \sqrt{{\mathrm{<figure-callout\; id="2"\; label="Y"\; filenames="imgf0001.png,imgf0002.png"\; state="\{\{state\}\}">Y</figure-callout>}}^2+{\mathrm{<figure-callout\; id="2"\; label="H"\; filenames="imgf0001.png,imgf0002.png"\; state="\{\{state\}\}">H</figure-callout>}}^2}+G$$

be satisfied, where Y is the extension of the cover 24 on the inside of the segments 10, H is the height of the projection 46 and G is a minimum gap required to be able to exclude a risk of crushing with sufficient certainty.

FIG. 8 also provides a bead-like bellows element 40 which covers the gap of the segment upper and lower edges of the segments 10 on the outside thereof when the segments 10 are pivoted relative to one another. The bellows member 40 is made of, for example, a resilient elastic material such as a rubber material or the like, and designed by suitable design of, for example, its wall thickness so as to be substantially flat against the outside thereof even in the stretched state of the segments 10.

A third embodiment is shown in Figs. 9A and 9B. These figures show two successive in the direction of movement of the door leaf 4 segments 10 with cover 24 in each case in a sectional view, wherein the line of sight and sectional view in Figure 9A corresponds to the representation in Figure 2, that is, a section along the line II-II in Figure 1, the section In FIG. 9B, the next higher or next lower segment is cut in a similar manner, and for reasons of clarity of drawing, the wall element 8, the frame 2, the running rail 18 and the seal 20 and the components lying behind the cutting plane are omitted.

The cover member 24 of this embodiment has a fixing portion 50 and a working portion 48. The working portion 48 serves to cover the frame portion, as indicated in the figures by the closure member 22, while the attachment portion 50 serves to secure the cover member 24 to the side wall 16 of the segment 10 by means of suitable fasteners or methods. As shown in the figures, the attachment portion 48 is twice the thickness of the working portion 50, with the attachment portion 48 and the working portion 50 having a common surface 52. By simply turning the cover members 24 such that at each second the common surface 52 faces the frame and the intermediate surface 52 faces away from the frame, the surfaces of the respective working portions 50 opposite the common surface 52 can pivot upon pivoting of the segments 10 slide past each other laterally. Although this results in a gap between the working portion 50 and the closure element 22, as shown in Figure 9B, every second cover member 24, but which is so small that a Hineingreifen should be largely excluded.

In the embodiment shown in Figs. 9A and 9B, the mounting portion 48 and the working portion 50, which is only half as thick, are made in one piece. Notwithstanding this, even a piece of consistently constant thickness in the region of the fastening portion 48 may be laminated or glued on a short piece of the same thickness in order to arrive at the shape shown in FIGS. 9A and 9B. As a further variant, it is also possible to use cover elements 24 of consistently constant thickness and only for every second cover element 24 for attachment to the side wall 16 of the corresponding Segments 10 underlay a piece of the same thickness to get the same operation.

It is understood that even in these variants of the present embodiment, which are not shown in the drawing, means are provided to prevent mutual interference of the opposite end faces of the cover 24. Again, this is done by projections 46, which are here but provided for reasons of symmetry on both end faces of the cover 24 and each overlap, as shown in Figure 10. Even at the bottom of the segments 10, this projection 46 should pose no problems, since the bottom of the segments 10 usually has a rather thick sealing bead on its underside, which ensures that the projection 46 does not touch the ground when closing the gate. (Where this is not the case, on the cover member 24 for the lowermost of the segments 10, the projection 46 on the underside must be removed at the latest during assembly.)

FIG. 10 also shows a sealing strip 41 which covers the gap of the segment upper and lower edges of the segments 10 on the outside thereof when the segments 10 are pivoted relative to one another. The sealing strip 41 is respectively secured to the upper two consecutive segments 10 and extends arcuately down until it rests with a sealing edge on the outside of the lower of the segments 10. Upon pivoting of the segments 10 against each other, the sealing edge of the sealing strip 41 slides upwards along the outside of the lower of the segments 10 and thus covers the gaping of the segments 10.

In the first to third embodiments shown in Figures 1 to 10, the cover 24 is a in essentially flat planar component which is fastened to the side wall 16 of the segment 10. Figure 11 shows a fourth embodiment of the present invention in a sectional view of a segment 10 and a cover 24, wherein the viewing direction and cut corresponds to the representation in Figure 2, but for reasons of clarity of the drawing, the wall element 8, the frame 2, the track rail 18 and the seal 20 and lying below the cutting plane components are omitted. Apart from the following, explicitly stated details, the features present in the preceding embodiments and variants can also be used in the present embodiment.

In the present embodiment, the cover 24 in profile a shape of an elongated "L" with a working leg 56 and a mounting leg 54. The working leg 56 serves to cover the Zargenbereichs, as indicated in Figure 11 by the end member 22. The mounting leg 54 projects at right angles away from the working leg and serves to secure the cover element to the inner wall 14 of the segment 10 by means of suitable fastening elements or methods. In this way, the facing to the frame surface of the cover 24 can be made flush with the side wall 16 of the segment 10 so as to be able to take into account cramped space between the segment 10 and the frame or the running rail 18. Also, the retrofitting of an existing door is simplified with the device of the present invention, since the attachment is made on the relatively easily accessible inside of the door. On an expansion of the segments 10 for assembly purposes, which may be necessary for lateral attachment of the cover 24 could be omitted in the present embodiment.

A fifth embodiment is shown in FIG. 12, the viewing direction and cut of which corresponds to that in FIG. In this embodiment, the cover member 24 is constructed in two parts with a base 58 and a male part 60. The base 58 is fixed to the inner wall 14 of the segment 10 and has a receptacle for the male part 60. The male member 60 is secured in the receptacle in the base 58 and serves to cover the Zargenbereichs, as indicated in Figure 12 by the closure element 22.

This embodiment is particularly advantageous when required by the cover itself properties that can not be reconciled with the requirements of attachment to the segment 10. For example, it may be desirable for the cover member 24 to have some compliance, but attachment to the segment 10 requires greater rigidity. In this case, using the principle of the present embodiment, a socket 58 may be made of a stiffer material than the plug 60.

It is understood that this principle can also be applied to a cover 24 which is to be fastened to the side wall 16 of the segment 10 (not shown in detail).

FIG. 13 shows a sixth embodiment of the present invention in a view similar to that in FIG. 2.

In the present embodiment, the cover member 24 in the (facing the frame) side wall 16 of Segment 10 integrated. That is, the side wall 16 is extended on the inside of the door so far that it serves as the cover 24, or the cover 24 simultaneously serves as the side wall 16 of the segment 10. With such a structure, the cost of manufacture, storage and assembly can be reduced by reducing the required components.

Further, in this embodiment, no termination member 22 is used. Rather, the profile of the frame 2 is bent back on the inside in a region 62 so that the region 62 forms a termination section, on which the side wall or cover 24 comes to lie flat. As a result, the number of required components can be further reduced and the total cost can be further reduced.

FIGS. 14 and 15 show a seventh embodiment of the present invention. Here, Fig. 14 is a horizontal sectional view taken along the line II-II in Fig. 1, and Fig. 15 is a sectional view taken along a line XV-XV in Fig. 14. As shown therein, the sectional plane in the vertical direction and perpendicular to the door leaf plane on the side of Frame directly next to the door leaf. The view is directed to the side of the door leaf 4. Unless otherwise indicated, like reference numerals designate like components throughout the present and the preceding embodiments.

In contrast to the embodiments described above, in which the cover member 24 extends at least from the segment 10 as a substantially planar member to the inside of the gate, the cover member 24 in the present embodiment, an extension in the lateral direction of the door leaf to Frame up to cover the frame area there as well. That is, a sheet member 63 (hereinafter referred to as "surface member" 63) formed on itself like the cover member 24 of the first embodiment is fixed to the frame 2 facing side wall 16 of the segment 10. At the edge of the surface part 63, which faces the inside of the door, a part 64 protruding at right angles to the frame 2 (hereinafter referred to as "transverse part" 64) and a part 68 projecting at right angles and leading back to the gate plane (hereinafter "closing part") 68). The cross member 64 and the end part 68 take on the task of the closure element 22 of the first embodiment and the final part 62 of the sixth embodiment by completing the area this box-like together with the surface portion 63 to the frame 2.

As in the first embodiment, adjacent end faces of the cover members 24 of two consecutive segments 10 each have a curvature following a cylinder surface about the pivot axis 26 of the segments. The rib portions 66 and 67 are used to stiffen the cover 24. The contour of the rib portions extending from the outer edge of the closure member 68 in. In each case perpendicularly from the surface portion 63 projecting rib portions 66 and 67 follow the contour of the lower and upper end oblique direction of the surface portion 63 to merge at a point between the cross member 64 and the segment 10 with the surface portion 63.

In the angled portion 64, a recess 68 is provided in the upper region, which serves to prevent the outer lower edge of the adjoining top cover member 24 upon pivoting of the segments 10 of the Angled portion 64 is impeded. It is understood that the recess 68 must be designed so that a risk of crushing is reliably excluded.

With the cover member 24 of the present embodiment, it is not necessary to take additional measures on the frame 24. The number of components and assembly operations required for the apparatus of the present invention is therefore further reduced.

Although the present invention has been described in several embodiments and variants thereof, these are not to be considered as isolated, but may be supplemented as needed. For example, it is clear that even in the side wall 16 of the segment 10 integrated cover 24 (sixth embodiment) may well be made in two parts such that the side wall 16 forms a base in which a plug is attached in the sense of the fifth embodiment, which is completely has certain material properties. It is also quite clear that all shown in Figures 3 to 10 and described in this context forms of the upper and lower sides of segments 10 and cover members 24 (first to third embodiment) readily to the fourth to sixth embodiments, which coincides with the Attachment of the cover 24 on the segment 10 deal, are transferable. It is also readily apparent that the cover members 24 with the straight lower and upper sides, the notches and projections of the second and third embodiments are applicable to a door leaf, the segments 10 have concave / convex upper and lower sides, as shown in the first embodiment is the case, and vice versa, if the position of the pivot axis 26 permits. Of course, the application of the frame 2 with the end portion 62 is not limited to an application in which the cover 24 is integrated into the side wall, as well as a frame 2 with a closure element 22 is also used in this case. The person skilled in the art will find in this application various suggestions for further ingenious combinations of the teachings of the different embodiments.

Likewise, other variants of the embodiments described above will be found easily. Thus, it may be advantageous, for example, if the resilience of the cover elements 24 increases towards the side of the closure element 22 or the closure section 62. Such variable material properties can be realized with today's processes for processing plastics, such as in advanced extrusion processes. The cover elements 24 and / or the closure element 22 may be made of plastic, metal, wood, a reinforced plastic or the like. The closure element 22 may be attached by any connecting elements and / or methods, more preferably by plugging and clamping on the frame 2. In the frame 2, the crank 21 can be omitted for receiving the closure element 22 when the frame 2 is not mounted flush with a wall.

It should be clearly understood that in a ceiling sectional door the described and illustrated components and proportions are found on both side frames of the door, while the invention in side sectional doors usually comes only on the upper frame used.
