Abstract

A door leaf, in particular of a sectional door, comprises a plurality of panels (10A, 10B, ...) which can be interconnected at their adjacent longitudinal sides (11A, 11B) by means of hinges (12), wherein the axis of rotation (12A) of the hinges (12) extends substantially in the centre of the thickness (W) of the panels (10A, 10B, ...), and wherein each longitudinal side (11A) of the panels (10A, 10B, ...) comprises a cylindrical, preferably circular cylindrical, joint sleeve (14) which substantially extends over the entire length of the panel and has an elongate slot for accommodating at least one hinge part (15B) which is connected to the adjacent longitudinal side (11B) of the next panel and is longitudinally displaceable in the joint sleeve (14). Inter alia, improved ease of passage is achieved in that multi-part strap hinges inserted into the joint sleeve (14) are provided with strap parts (12B, 12C) which can be rotated relative to one another about a common axis (12A), and in that at least one respective first strap part (12C) is secured in a position to be determined along the joint sleeve (14) on the panel (10A, 10B, ...) comprising the joint sleeve and at least one second respective strap part (12B) is secured in a position to be determined along the next panel by means of a strap tab (12D) engaging through the elongate slot (14A) of the joint sleeve (14).

Description

Door leaf

The invention relates to a door leaf comprising a plurality of panels connected to one another on their adjacent longitudinal sides via hinges, in particular a liftable sectional door, in which the axis of rotation of the hinges runs largely in the middle of the thickness of the panels, and in which the respective one The longitudinal side of the panels has a longitudinally slotted, cylindrical, preferably circular-cylindrical joint sleeve which extends essentially over the entire length of the panel and for receiving at least one hinge part which is longitudinally displaceable in the joint sleeve and connected to the adjacent longitudinal sides of the next panel.

Because of the central position of the axis of rotation related to the thickness of the door leaf, such door leaves offer for the mutual pivoting of the individual panels or sections of the door leaf and in connection with the largely closed one, which extends over the entire length of the panel and only the mutual maximum swivel angle of Joint sleeves that allow panels to allow one another longitudinal slot naturally provide relatively good protection against the jamming of objects, in particular the fingers of one

REPLACEMENTB Operator when pivoting the panels to each other from or into the mutual extended position.

A door leaf provided with the hinges described above is known from EP 0 212 009 A2. The joint sleeve formed in one piece with the panel profile completely covers the gap on the inside of the door necessary for the panels to be pivoted relative to one another. On the longitudinal side of each panel opposite the joint sleeve, a circular cylindrical tubular profile is formed over the entire profile length, the outer diameter of which coincides with the inner diameter of the joint sleeve. This creates a continuous hinge over the entire length of the panel. For assembly, the adjacent panels must be pushed together from one end over the entire length of the panel. This work takes up a lot of space and takes place under considerable frictional resistance between the joint sleeve and the profiled tube serving as a joint pin.

The door leaf according to DE 93 16 396 Ul makes use of the same hinge type as EP 0 212 009 A2. In this door leaf too, a tubular profile serving as a hinge pin is arranged completely on the one longitudinal side of the panel within the door leaf thickness. The axis of rotation is laterally offset by the dimension of about a quarter door leaf thickness from the door leaf center to a door surface. This position is also understood here as "largely in the middle of the thickness of the panels". In this door leaf, due to the asymmetrical arrangement of the axes of rotation on the door inner surface closer to the axis of rotation, an effective finger protection is achieved. In order to achieve this goal also on the outside of the door leaf, the axis of rotation and the longitudinal

LEEPED BLAΓT <RULE *

ISA / EP slotted circular cylindrical joint sleeve too far from the outside of the door leaf. So that effective finger protection is nevertheless achieved on the outside of the door, which is particularly prone to jamming, there is an annular segment-shaped gap on the radial outer side of the joint sleeve on a partial circumference of the joint sleeve and the adjacent panel carrying the joint pin has a circular segment segment surrounding the joint pin with a radial spacing which, on its radial inside, encloses the outside of the joint sleeve and can be pivoted into the curved longitudinal slot on the radial outside of the joint sleeve when adjacent panels are pivoted out of the bent position into the extended position.

A circular segment-shaped profile in the hinge area of neighboring door leaf panels, which with its outer surface coaxial with the axis of rotation of the hinge in all pivoting positions of the adjacent panels is always very close to the outer surface of the door leaf, is also known from DE 40 19 569 AI - but as an additional, only component serving as finger protection, which has no hinge function.

Finally, from DE 39 06 486 AI a sectional door is known in which the door leaf sections carry a plurality of axially spaced tube sections on their adjacent long sides, the tube sections being arranged on the adjacent long sides of adjacent door leaf sections in such a way that all the tube sections follow one another assemble the assembly into a hinge that extends over the entire section length without any significant axial spacing of the pipe sections. In addition, since the tube sections forming the hinge parts have approximately the same outer diameter as the thickness of the door leaf.

BβATZBLΛT RULE 26 In this sectional door, the finger pinch protection is realized in a practically ideal way - but with the expense of considerable manufacturing and assembly costs when screwing the pipe sections flush and precisely on the long sides and when inserting the hinge bolts over the entire length of the panel. The manufacturing effort is also great if the pipe sections are not created by screwing them on, but are created by providing panels with pipes connected to them in one piece on the longitudinal sides and by milling out the spacing gaps for the pipe sections of the associated adjacent panel.

Door leaves according to the invention reproduced in claim 1 have considerable advantages over the known door leaves of the generic type with the same size or even increased finger pinch protection: primarily a hitherto unknown ease of movement of the hinges is made possible - both during assembly and during which the individual hinge parts are inserted one after the other and not at the same time into the joint sleeve from a front end, as well as when using the door leaf, since the hinge surfaces in frictional contact can be concentrated on areas specially designed for this purpose and the surface quality on the inner surface of the Joint sleeve is practically meaningless for normal door operation. Even if one band part after the other were inserted without an axial distance from one another into the joint sleeve, the friction dependent on the surface quality of the joint sleeve would be reduced by about half compared to the prior art, because one half of the band parts on which the Panel with joint sleeve is fastened and does not rotate relative to the joint sleeve. If - as preferred - the band connected to the panel not having the joint sleeve parts form a small spacing gap with the inner surface of the longitudinally slotted joint sleeve, any friction on the inner joint sleeve surface is even eliminated in use. Instead, all frictional forces can be concentrated on specially designed areas and material combinations. In particular, the low friction can be further improved by using roller bearings, in particular needle bearings and possibly ball bearings.

The inner cross section of the longitudinally slotted joint sleeve is - as is known per se - preferably circular-cylindrical, because this allows the use of the largest possible roller bearings and tubular components. But it is also a non-circular cylindrical cross section of the longitudinally slotted joint sleeve realizable, such as. B. a regular hexagon cross-section, so that any torque can be distributed over a large area on the longitudinally slotted joint sleeve.

In the simplest case, the band part to be fastened to the panel having the joint sleeve can in the simplest case consist of only one pipe section which is screwed to the joint sleeve in its installed position. For example, a fastening of the type described in DE 39 06 468 A1 is possible, namely the use of a countersunk screw inserted through a transverse bore into the pipe section and inserted through an opposite fastening hole. In this respect, DE 39 06 468 AI is included in the present disclosure by its mention. However, an embodiment is preferred in which at least the band parts fastened to the long side having the joint sleeve have a band tab which extends through the longitudinal slot of the joint sleeve and is attached to the panel outside the joint sleeve.

SPARE BLADES (RULE 26) Longitudinal grooves in the area of the long sides of the panels are preferred for fastening the band tabs. These longitudinal grooves preferably open with a directional component pointing to the adjacent panel, preferably at approximately 45 ° in relation to the surface spanned by the door leaf in the extended position. As a result, hinge tabs and fastening screws that exceed the door leaf thickness are avoided.

In the area of the band tabs, the section joints are preferably covered by an elastic band, the edges of which are preferably held in the longitudinal grooves provided near the long sides of the panels.

The above-mentioned components to be used according to the invention are not subject to any special exceptional conditions in terms of their size, shape, material selection and technical conception, so that the selection criteria known in the respective field of application can be used without restriction.

Further details, features and advantages of the subject matter of the invention result from the following description of the accompanying drawing, in which - by way of example - a preferred embodiment of a device according to the invention is shown.

Fig. 1 shows two adjacent, articulated panels of a sectional door in the extended position in sections;

Fig. 2 shows the same representation in a kink position;

3 shows the hinge shown in FIGS. 1 and 2 in axial section (section along line B-B according to FIG

SPARE BLADE RULE 26 Fig. 4) as well

Fig. 4 of the hinge of Fig. 3 in three end views, partially broken.

According to FIGS. 1 and 2, a closed, foamed panel 10A of a sectional door is on its upper longitudinal side ILA with the lower longitudinal side 11B of a panel 10B located above it and provided with a panel filling 13, such as a double glass pane, by means of multi-part hinges 15A, 15B in an articulated manner in a manner pivotable from the extended position by approximately 90 °. The frame profiles 28, 29 shown in vertical section through the door leaf consist of aluminum profiles of constant profile cross section produced by the extrusion process.

The frame profile 28 has an annular joint sleeve 14 over its entire length. This is longitudinally slotted on the inside of the gate, the longitudinal slot 14A corresponding approximately to an angular range of 110 °.

The hinge consisting of the hinge parts 15A and 15B is extruded from aluminum and then sawn into the hinge parts 15A and 15B. They consist of the sleeve-shaped band parts 12C and 12D and the band tabs 12E and 12D connected in one piece to them. The details of this hinge will be explained in connection with FIGS. 3 and 4.

The two hinge parts 15A, which are axially outer with respect to the hinge part 15B, fit with their circular cylindrical outer diameter into the longitudinally slotted joint sleeve 14 with only slight radial play. They are used for pre-assembly from one end without taking up much space

REPLACEMENT OIL (RULE 26) pushed and pushed into the various hinge positions of the panel 10A. They are fixed by means of a screw 21 which engages the band tab 12E in a threaded bore 21A.

All band tabs are provided with approximately T-shaped guide and holding bodies 30A and 30B, which receive the threaded bores 21A, 22A for the screws 21 and 22. These guiding and holding bodies fit into corresponding cross-sectional longitudinal grooves 17A and 17B in the area of the longitudinal sides 11A and 11B of the individual panels. These longitudinal grooves open at approximately 45 ° to the door surface and serve as a sliding seat for the guide and holding bodies 30A, 30B and to increase the rigidity of the frame profiles 28 and 29. When the hinge parts 15A are inserted into the joint sleeve 14 from one end face the guide and holding body 30A is inserted into the associated longitudinal groove 17A at the same time. After shifting into the target position along the panel, only the screw 21 needs to be clamped against the groove base of the longitudinal groove 17A. In this way, the panel can be delivered completely pre-assembled to the installation site without any parts protruding beyond the side surfaces of the panel. The same applies to the hinge parts 15B, which are brought into the desired position by longitudinally displacing the guide and holding body 30B in the longitudinal groove 17B and are fixed in position there by means of the screw 22.

In this way, the hinge forces can be effectively introduced into the frame profiles 28 and 29 without the joint sleeve 14 being excessively loaded.

A spacing gap G is deliberately left between the band part 12B and the hinge sleeve 14, so that the gate operates any friction towards the joint sleeve is avoided. Two flats 16 lying opposite one another on the band parts 12B are dimensioned such that in the kink position shown in FIG. 2 the band part 12B fastened to the panel 10B can be pulled out through the longitudinal slot 14A of the joint sleeve 14 and pushed in through it, which of course can be done with missing hinge pin happens.

1 and 2 also show an effective elastic sealing profile 23 on the outside of the door leaf, with which the joint sleeve 14 is sealed, at least in the extended position, against the longitudinal side 11B of the adjacent panel 10B which is adapted to the shape of the joint sleeve 14. In connection with the sealing tape 18, this creates a practically completely moisture and dust-protected articulated connection over the entire length of the panel.

As particularly illustrated by way of example in FIG. 3, if desired, each of the hinge parts 15A and 15B can be roller-supported. For the hinge part 15B, a needle bearing 24 corresponding to its length is preferred, which is pressed into the clear cross section of the band part 12B.

In addition to the hinges provided on both ends of the panel, one of which is shown in FIG. 3, a roller bearing in the area of the hinge parts 15A is unnecessary for the other hinges distributed over the panel length. These are then fully booked with plastic bushings 25 over their entire length. The hinge pin 20 can be inserted in the usual manner from one end face into each individual hinge. The width of the longitudinal slot 14A in the extended position of the panels is completely sufficient for this. If the door is guided on both sides of the door over door rails and corresponding rollers, the hinge pin 20 is provided at one end with corresponding rollers (tandem rollers 26 in the drawing). Since the pin 20 is rotated about its axis in the bending region of the door guides when tandem rollers are used, end-face ball bearings 27 are provided for reducing friction with respect to the hinge parts 15A.
