Definitions
- the present invention relates to a door panel or door leaf of the type comprising a plurality of successive ⁇ sive, mutually rotatable, separate panels.
- the inventive door leaf may be used for, for instance, but not exclu ⁇ sively, an overhead sliding door whose door leaf is mov ⁇ able between an essentially vertical closed position and an essentially horizontal open position.
- neighbouring panels of such door leaves for overhead sliding doors are rotatably connected to each other by means of a plurality of sepa ⁇ rate hinges which are distributed over the width of the door leaf and which are normally made of metal and whose hinge plates are attached by screwing, riveting or in some other way to the inner panel surfaces of the door leaf in order to rotatably join the panels.
- the axis of rotation as defined by each hinge is positioned in or in the immediate vicinity of the plane that coincides with the inner boundary surface of the door leaf.
- US 4,924,932 discloses a door leaf comprising a plurality of successive, separate panels and, between any two neighbouring panels, a link element continuously extending along essentially the entire width of the door leaf, said link element defining an axis of rotation around which the two neighbouring panels are adapted to rotate relative to one another, and including a male sec ⁇ tional element arranged on one of the neighbouring panels and having a convex surface concentric with the axis of rotation, and a female sectional element arranged on the other one of the neighbouring panels and having a concave surface mating the convex surface and concentric with the axis of rotation.
- the link element of this prior art door leaf is distinguished in that the link element in itself functions as a vertically joining hinge.
- This joining hinge function is achieved by the concave surface of the female sectional element enclosing the convex surface of the male sectional element through about 270° such that the sectional elements hook into each other.
- the panels When assem ⁇ bling such a link element between two neighbouring panels, the panels must be held almost perpendicular to each other to make it possible to insert the female sec ⁇ tional element into the male sectional element. After this insertion and after having rotated the two panels in the direction of a mutually parallel position, the male sectional element is locked in the female sectional ele ⁇ ment and the link element functions as a vertically join ⁇ ing hinge, which extends continuously in the transverse direction of the door leaf.
- EP-B1-0 304 642 shows (Figs 8 and 9) a construction having essentially the same function as the one in the above-mentioned US-4,924,932.
- US 5,148,850 describes a door leaf comprising a plu ⁇ rality of successive, separate panels and, between any two neighbouring panels, a link element continuously extending along essentially the entire width of the door leaf and arranged to join the neighbouring panels.
- the continuous link element consists of an elongate rubber strip or the like, which extends along essentially the entire width of the door leaf and is attached along the inner surface of each panel.
- the elongate rubber strip functions as a continuous hinge, as well as a sealing element.
- the central portion of the rubber strip defines the axis of rotation of the two neighbouring panels, said axis of rotation, like in the above-mentioned traditional solutions with separate hinges, thus being positioned at the inner surface of the door leaf.
- US 2,300,265 discloses an overhead sliding door comprising a plurality of successive panels, whose ends are rotatably united by means of hook-type hinges.
- the adjoining edges of the panels in the transverse direction are so designed that they keep the panels in one and the same plane along the entire width of the door and simul- taneously permit the panels to turn in a predetermined direction relative to each other, such that the door can be moved through a 90° bend from a vertical closed posi ⁇ tion to a horizontal open position.
- the adjoining edges of the neighbouring panels are almost designed as turn- able tongue-and-groove joints.
- the object of the invention is to provide a door leaf which does not suffer from the above-mentioned draw ⁇ backs of the prior-art technique. More specifically, the object of the invention is to provide a door leaf: - which is bump resistant or impact resistant and is not permanently damaged or deformed after being bumped into or subjected to an impact,
- the inventive door leaf thus comprises a plurality of successive, separate panels and, between any two neighbouring panels, a link element extending over essen ⁇ tially the entire width of the door leaf and defining an axis of rotation, around which the two neighbouring panels are adapted to rotate relative to one another, said link element including a male sectional element arranged on one of the neighbouring panels and having a convex surface concentric with the axis of rotation, and a female sectional element arranged on the other one of the neighbouring panels and having a concave surface, which mates the convex surface and is concentric with the axis of rotation.
- the impact-resistant door leaf accord- ing to the invention is characterised in that said convex and concave surfaces constitute sliding surfaces, which engage with each other and together serve as a knee joint when mutually rotating the neighbouring panels around the axis of rotation, that the concave sliding surface of the female sec ⁇ tional element encloses the convex sliding surface of the male sectional element through such a restricted angle that the link element in itself permits an unimpeded ver ⁇ tical separation of the two neighbouring panels, but counteracts a mutual horizontal displacement of the panels perpendicular to the axis of rotation, that, at each end of the link element, there is arranged an end coupling means preventing separation of the ends of neighbouring panels, and that the link element and the panels are made of flexible material.
- the end coupling means serve the traditional purpose of joining the panels and have the function, which is new to the invention, of ensuring that also when subjected to impact, two portions with an intact hinge function remain, causing the link element to be automatically reset after being bumped into or sub ⁇ jected to a similar impact.
- the axis of rotation of the link element is, accord ⁇ ing to the invention, defined by and concentric with the convex and concave sliding surfaces of the link element, and, neighbouring panels, when subjected to impact, should, according to the invention, be able to divide essentially unimpededly. This does not necessarily imply that the panels are not allowed to be interconnected somehow between the ends of the link element. According to a preferred embodiment of the invention, there is along the link element no joining means in addition to the above-mentioned end coupling means, which prevent separation of but the ends of neighbouring panels.
- the door leaf will be highly resistant to impact, since the transverse, ver ⁇ tically not joining link element can divide, when bumped into or subjected to any other impact, without any hinges breaking.
- the division of the link element is possible owing to the link element and the panels being manufactured of flexible material and the link element in itself having no joining hinge function, but a "knee joint function" only.
- one or more panels can therefore bulge in the direction of impact, and be sepa ⁇ rated from neighbouring panels a distance whose length depends on the amount of the force of impact. If the link element, when subjected to impact, divides in this man ⁇ ner, it will be reset on the one hand owing to the arrangement of the end coupling means which at each end of the link element prevent separation of the ends of neighbouring panels and, on the other hand, owing to the link element and the panels being flexible transversely of the plane of the door leaf.
- the link element is intact at both ends even when subjected to impact, i.e. the male sectional element and the female sectional ele ⁇ ment are substantially correctly positioned relative to each other at the ends of the link element.
- a division of the link element between the ends will ensure, owing to said flexibility, that the link element is automatically reset if being bumped into or subjected to a similar im ⁇ pact.
- the special knee joint construction between the panels with its rounded engaging surfaces contributes to this resetting function.

- Fig. 2 is a cross-sectional view, taken along line II-II in Fig. 1, of a panel and the associated link ele ⁇ ments.

- Fig. 6 is a cross-sectional view of a panel accord ⁇ ing to a second embodiment of the invention.
- Figs 7A-7C are a side view, a horizontal sectional view and a vertical sectional view of a panel core.
- Fig. 7D is a cross-sectional view of an outer element.
- Fig. 7E is a cross-sectional view of a reinforcing sec- tional element.
- Figs 8A-8E schematically illustrate a method for making a panel based on the parts in Figs 7A-7E.
- Fig. 1 illustrates a lower part of a vertically extended door leaf composed of horizontal, rectangular panels 2, between which there are arranged continuous, elongate link elements 4 according to the invention.
- Each link element 4 defines an axis of rotation A around which neighbouring panels 2 can rotate in relation to each other.
- the length of the link elements 4 essentially equals the width of the door leaf.
- the link element according to the invention can be designed to be continuous or consist of a plurality of successive parts, which optionally can be positioned at a relatively small distance from each other in the longitu- dinal direction of the link element.
- each such joining means consists of a hinge, whose hinge pin coincides with the axis of rotation A.
- Each hinge comprises two hinge plates 6 which are each screwed to a reinforcing sectional element 8 attached to and extending along the side edge of the respective panel 2.
- the hinge plates are rotatably mounted on a hinge pin 10, which is connected to a guide means 12.
- the guide means 12 which are adapted to be guided by and slide along guides (not shown) positioned on both sides of the door leaf, can preferably be such flexible guide means as described in Applicant's Swedish patent application entitled “Door edge guiding arrangement", which has the same filing date as the present application and to which reference is made for more details regarding the flexibi- lity of the guide means 12.
- the engagement of the guide means 12 with the guide is such as to allow a rotary motion of the guide means 12 relative to the guide in a plane perpendicular to the longitudinal direc- tion of the guide.
- Fig. 2 is a cross- sectional view of the lowest but one panel 2 in Fig. 1.
- the panel 2 is composed of two outer elements 20 attached to a panel core 22.
- An upper edge 24 and a lower edge 26 of each outer element 20 extend over the longitudinal edge surface 28 of the core 22 so as to form, together with the upper edge 24 and the lower edge 26, respec ⁇ tively, of the opposite outer element 20, an upper and a lower groove 30 and 32, respectively, which thus extend along the entire width of the panel 2.
- a male sectional ele ⁇ ment 4A and a female sectional element 4B of the appear ⁇ ance illustrated in Fig. 3 are inserted in the grooves 30, 32 of the panel 2, thereby forming the link element 4.
- the link sectional elements 4A, 4B are each provided with a lug 34 to be held in the respective groove 30, 32.
- the male sectional element 4A has a convex sliding sur ⁇ face 36, which in the illustrated embodiment describes a cylindrical surface through essentially 270°.
- the female sectional element 4B has a mating concave sliding surface 38, which describes but a smaller angle.
- the concave sliding surface 38 of the female sectional ele- ment 4B is composed of, starting from the vertical line V, a portion facing the outside of the door leaf and describing an angle of about 90°, and a shorter portion facing the inside of the door and describing an angle of about 45°. Thanks to the 90° outer portion not extending beyond the horizontal line H, this portion will not pro ⁇ note a vertically joining effect. Thanks to the inner portion extending through 45° only, the link element 4 can, as illustrated in Fig. 4B, be rotated to a requisite extent, without the female sectional element 4B striking against the panel that supports the male sectional ele ⁇ ment 4A. The outer portion of the concave sliding surface 38 could, however, extend through a smaller angle than 90°.
- the link element shown in Figs 5A and 5B is essen ⁇ tially identical with the link element in Figs 4A and 4B, but is supplemented with a sealing element 40 attached to the outer part of the female sectional element 4A and consisting of a continuous, elastic sealing strip, whose opposite longitudinal edges 42 constitute lips which, in the closed position of the door (Fig. 5A) seal against the exteriors of the panels.
- Fig. 6 shows a second embodiment of the invention.
- the male sectional element 4A and the female sectional element 4B are integrated with the actual panel 2.
- the panel 2 can suitably (but not exclu ⁇ sively) be extruded as a closed casing, which is then divided into suitable lengths.
- the wall of the casing then constitutes two opposite parallel main walls 50, which are joined by integrated end walls 52 and 54 designed as shown in Fig. 6, thereby forming a male sec ⁇ tional element 4A and a female sectional element 4B, respectively.
- Those parts of the casing which form the sliding surfaces 36, 38 can optionally be made to have other properties than the rest of the casing, for example of a more durable material than the rest of the casing and/or be made with a greater thickness of the material as shown in Fig. 6.
- the interior of the casing is filled with a suit ⁇ able filling 56, for example a core of expanded styrene foam which is introduced later, or polyurethane foam which is foamed inside the casing to the final shape.
- a suit ⁇ able filling 56 for example a core of expanded styrene foam which is introduced later, or polyurethane foam which is foamed inside the casing to the final shape.
- those parts of the casing which form the slid ⁇ ing surfaces 36, 38 can consist of different materials in the thickness direction of the casing, for example by applying foils to the casing, by spraying, chemical reac ⁇ tions etc.
- the panel 2 is, like the link element 4, made of flexible material to make it pos- sible for the link element 4 to divide if being bumped into or subjected to any other impact.
- a method of making such a flexible panel will now be described with reference to Figs 7 and 8.
- Figs 7A-7C are a side view, a horizontal sectional view and a vertical sectional view of a panel core 22 of the type included in the panel shown in Fig. 2.
- the panel core 22 is, at each terminal edge surface 60, provided with a narrower portion 62 extending along the height of the entire core 22.
- material for the panel core 22 use can be made of, for instance, blown polystyrene, such as StyrofoamTM, which has closed cells that cannot take up moisture, which is advantageous in moist surroundings.
- Fig. 7D is a cross-sectional view of a substantially U-shaped outer element 20, which should constitute the outer layer of the finished panel.
- the outer element 20 can be made of polycarbonate or the like.
- FIG. 7E is a cross-sectional view of a reinforcing sectional element 8 of the type which is used in Fig. 1 at each panel termi ⁇ nal edge and to which the hinge plates 6 are attached.
- the sectional element 8 is of substantially I-shaped cross-section and has, at one flange, a groove 64 adapted to receive the hinge plates 6 and, at its other flange, two serrated securing portions 66, whose mutual distance conforms with the panel thickness at the narrower end portion 62 of the core 22.
- a first U-shaped outer element 20 of the type illustrated in Fig. 7D is arranged on a base 70.
- a binder 74 of some suitable type, such as a hot-setting agent is applied to the entire main surface of the outer element 20.
- a panel core 22 of the type shown in Figs 7A-7C is arranged on the outer element 20 provided with the binder.
- a binder 74 and a second outer element 20 are applied to the opposite main surface of the panel core 22. Subsequently, a reinforcing sectional element 8 is mounted on each panel terminal edge 60, the serrated securing portions 66 being fitted into the spaces between the outer element 20 and the narrower portion 62 of the panel core 22.
- the panel cores 22 can be formed with through recesses for making panels with windows.
- the outer elements 20 can then be made of some suitable transparent material.
- a colouring effect can also be achieved by using a coloured binder 74.
- a further possibility is the arranging of a metal foil, for example having a logotype, between the core 22 and a transparent outer element 20.
- the panel 2 can be equipped with rein ⁇ forcing elements, on the one hand for the purpose of enhancing the resistance of the panels to load due to wind pressure, and on the other hand for the purpose of preventing too great a slack if the panels extend hori ⁇ zontally between the guides in the open state of the door.
- Such reinforcing elements may consist of, for instance, glass fibre elements of high tensile strength, thin metal strips or the like, arranged over the length of the panel on both main surfaces of the core. By arranging these elements at a distance from the centre of the panel core, they will impart flexural rigidity to the panel. For example, in Fig. 8B and Fig. 8E, respectively, such reinforcing elements can be inserted between the binder 74 and the outer element 20.
