Description

ENTRANCE SYSTEM

Technical field

The present invention relates to the technical field of overhead door systems in general and overhead sectional door system in particular.

Background

Entrance systems having manual doors, doors with door closers or automatic doors can be found in various buildings today. Such entrance systems allow access to the building for pedestrians or vehicles while also enabling a desirable indoor climate and temperature inside the building.

In some applications overhead sectional doors are utilized. Overhead sectional doors are often implemented as garage door systems and industrial door systems. Overhead sectional doors may comprise a plurality of interconnected door panels or sections.

Also, today's overhead sectional door often have sandwich panels, but the bottom profile for a pedestrian door is not insulated, which may cause a high loss of energy through the threshold. Further, in circumstances of a large difference between inside and outside temperature condensation may occur or ice on the inside of the door may form due to the heat transfer through the profile elements of the sectional door. Thus, there is a need for a solution which mitigates condensation or forming of ice on the inside of the door.

Such overhead sectional doors comprises a set of profile elements forming the overall construction of the sectional door system and panel elements mounted by means of said profile elements. The overhead sectional door systems are often utilized to cover large openings, this causes the sectional door leaf of the system to have a large surface area. The large surface area increases the load which the door is subjected to in terms of wind, weight etc. Thus, there is a need for a solution which increases the door’s ability to take up load. Overhead sectional doors may in some cases be provided with an additional door leaf suitable for pedestrians or smaller objects. The door leaf is preferably a swing door leaf mounted in a door frame in the overhead door. The door leaf allows for easy access for a pedestrian, since the entire sectional door leaf does not have to be opened. Such overhead sectional doors comprises a set of profile elements forming the overall structure and panel elements mounted by means of said profile elements. A bottom profile element forms a threshold element for the swing door leaf and is fixedly mounted to the bottommost door panel.

Integration of the pedestrian door leaf in the overhead door leaf is associated with a number of challenges.

The pass door leaf integrated into the overhead door creates a cut-out in the door panels which thereby cannot take up load. This increases the risk for the door panels bending due to wind and the weight of the overhead door. The bending may cause the integrated door leaf to malfunction, since the opening of said integrated door leaf requires the door leaf to be aligned with the remaining overhead door leaf.

Also, the threshold between the integrated pass door leaf and the bottom profile is subjected to heat transfer. Thus, there is a need for a solution which mitigates heat transfer through the threshold between the pass door leaf and the bottom profile.

The present inventor has realized that there is room for improvement in this field.

Summary

An object of the present invention is therefore to provide one or more improvements in the field of entrance systems having automatic door operators for causing movements of one or more movable door members between closed and open positions.

Accordingly, an overhead door system is provided. The sectional door system comprises a sectional door leaf. The sectional door leaf has a plurality of horizontal sections. The sectional door leaf is movable between a vertical closed position and a horizontal, opened or overhead position within a guiding track system. The sectional door leaf has an inner and outer door surface forming vertical planes when said sectional door leaf is in the vertical closed position. The sectional door leaf comprises a bottom profile mounted to a bottommost horizontal section. The bottom profile is arranged to come into contact with the floor of an opening in which the sectional door system is provided when the sectional door leaf is in the vertical closed position. The bottom profile comprises an insulating arrangement. The insulating arrangement comprises at least one strip in a low heat conductivity material extending along the bottom profile.

Embodiments of the invention will now be described with reference to the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The terminology used in the detailed description of the particular embodiments illustrated in the accompanying drawings is not intended to be limiting of the invention. In the drawings, like numbers refer to like elements.

According to an aspect a sectional door system comprises a sectional door leaf 1 having a plurality of horizontal sections 11, 12, 13. The sectional door leaf is movable between a vertical closed position and a horizontal, opened or overhead position within a guiding track system (not shown).

The guiding track system typically comprises two guide tracks, wherein one guide track is arranged at each side of the sectional door, i.e. one guide track on the right side of the sectional door and one guide track on the left side of the sectional door. Each guide track comprises a vertical track portion, a horizontal track portion and a curved track portion connecting the horizontal and vertical track portions. Hence, the guiding track system comprises a pair of vertical tracks and a pair of horizontal tracks connected by a pair of connecting track portions.

In one embodiment, the sectional door leaf 1 may comprise a pass door 2 arranged in a pass door opening of the section door leaf. The pass door 2 is thus integrated into the sectional door leaf 1. In one embodiment, the sectional door leaf 1 may be a sectional door leaf 1 without a pass door, i.e. a sectional door leaf with continuous horizontal sections. The pass door 2 may be a swing door. The pass door 2 is hinged along a door swing axis. The door swing axis extends orthogonally to the horizontal sections of the sectional door leaf, i.e. extends vertically when the sectional door leaf 1 is in the vertical closed position.

The sectional door leaf 1 has an inner door surface forming a vertical plane when the sectional door leaf 1 is in the vertical closed position, i.e. a vertical plane extending along the inner door surface. The sectional door leaf 1 has an outer door surface forming a vertical plane when the sectional door leaf 1 is in the vertical closed position, i.e. a vertical plane extending along the outer door surface.

The sectional door leaf 1 further comprises a bottom profile 230 mounted to a bottommost horizontal section 11 arranged to come into contact with the floor of an opening provided with the sectional door system when the sectional door leaf 1 is in the vertical closed position. The bottom profile 230 defines a bottom edge of the pass door opening.

Bottommost horizontal section 11 does herein refer to the section which is bottommost when the sectional door leaf 1 is in the vertical closed position, i.e. the section which is disposed closest to the floor of the opening into which the sectional door system is mounted when the sectional door leaf is in the vertical closed position.

The number of horizontal sections 11, 12, 13, 14 is dependent on the height of the sectional door, i.e. the total height of the sectional door leaf. According to the embodiment depicted in Figure 1, the sectional door leaf 1 may comprise four horizontal sections 11, 12, 13, 14.

The horizontal sections 11, 12, 13, 14 of the sectional door 1 may be pivotally interconnected. Further referencing Figure 1, the horizontal sections 11, 12, 13, 14 may be connected to each other by means of hinges 501, 502. Each section is hinged to at least one other section by means of hinges. The pass door sections are hinged to each other by means of hinges 502. The main sections are hinged to each other by means of hinges 501.

When the sectional door leaf 1 is guided by the tracks of the guiding track system during opening and closing of the sectional door the sections will pivot in relation to each other due to the shape of the guide tracks which has both a vertical and a horizontal portion. The hinges 501, 502 are typically located on the backside of the door. Since the hinges are located on the backside, i.e. the inner side, of the sectional door, the gap between the front surfaces of the sections increases when the sections are pivoted during opening of the sectional door and decreases when the sections are pivoted during closing of the sectional door. In one embodiment wherein the sectional door leaf 1 comprises the pass door 2, at least two of the horizontal sections 11, 12, 13, 14 may be a horizontal primary section 11, 12, 13. A horizontal primary section is a horizontal section comprising a primary pass door section. Thereby, a horizontal primary section is a horizontal section that comprises a pass door section but no upper door frame, i.e. a horizontal primary section is a horizontal section below the uppermost horizontal section that comprises a pass door section, as seen when the sectional door is vertically arranged, such as when the sectional door is closed, i.e. when the sectional door leaf 1 is in the vertical closed position.

In one embodiment wherein the sectional door leaf 1 comprises the pass door 2, one of the horizontal sections 11, 12, 13, 14 may be a horizontal secondary section 14. A horizontal secondary section is a horizontal section comprising a secondary pass door section. Thereby, a horizontal secondary section is s horizontal section that comprises a pass door section that has an upper door frame, i.e. a horizontal primary section is the uppermost horizontal section that comprises a pass door section. The sectional door system shown in Figure 1 comprises one horizontal secondary section 14. This reasoning, as well as the explanations herein, assumes a sectional door having only one pass door. However, a sectional door can comprise two or more pass doors and a skilled person realizes how the explanations of the present invention could be adapted thereto.

In one embodiment wherein the sectional door leaf 1 comprises the pass door 2, one of the horizontal sections 11, 12, 13, 14 is a horizontal tertiary section (not shown). A horizontal tertiary section is a horizontal section without a pass door section.

Thereby, a horizontal tertiary section is a horizontal section above the uppermost horizontal section that comprises a pass door section. The sectional door system shown in Figure 1 does not comprise any horizontal tertiary sections. The number of horizontal tertiary sections is dependent on the height of the sectional door and the height of each horizontal tertiary section and may also be dependent on the number and height of the horizontal primary sections and the height of the horizontal secondary section.

Each horizontal primary section 11, 12, 13 comprises a primary pass door section 201, 202, 203, a first main section 101, 102, 103 and a second main section 104, 105, 106. The first main section 101, 102, 103 is arranged at a first side of the primary pass door section 201, 202, 203, i.e. a right side. The second main section 104, 105, 106 is arranged at a second side of the primary pass door section 201, 202, 203, i.e. a left side. The primary pass door section 201, 202, 203 is arranged between the first main section 101, 102, 103 and the second main section 104, 105, 106. In the sectional door system shown in Figure 1, the first main section 101, 102, 103 is arranged on the right side of the primary pass door section 201, 202, 203 and the second main section 104, 105, 106 is arranged on the left side of the primary pass door section 201, 202, 203 as seen from the outside of the sectional door (as seen in Figure 1). The sectional door shown in figure 1 comprises three primary pass door sections 201, 202, 203, three first main sections 101, 102, 103 and three second main sections 104, 105, 106. The first main section 101, 102, 103 can also be denoted first primary main section 101, 102, 103. The second main section 104, 105, 106 can also be denoted second primary main section 104, 105, 106.

In one embodiment, the horizontal secondary section 14 comprises a secondary main section 107 and a secondary pass door section 204. The secondary main section 107 comprises a cutout for the secondary pass door section 204. The secondary pass door section 204 is the uppermost pass door section. The secondary pass door section 204 is surrounded by the secondary main section 207 on the left side, the right side and the upper side of the secondary pass door section 204. On the lower side, the secondary pass door section 204 is surrounded by a primary pass door section 203. The secondary pass door section 204 is hinged to the uppermost of the primary pass door sections 203. In one embodiment, the secondary main section 107 comprises a first main section edge 127. The secondary main section 107 faces the secondary pass door section 204. In one embodiment, the secondary main section 107 comprises a second main section edge facing the secondary pass door section 204. In one embodiment, the secondary main section 107 comprises a top main section edge facing the secondary pass door section 204. In one embodiment, the secondary pass door section 204 comprises a first pass door section edge facing the first main section edge of the secondary main section 107. In one embodiment, the secondary pass door section 204 comprises a second pass door section edge facing the second main section edge of the secondary main section 107. In one embodiment, the secondary pass door section 204 comprises a top pass door section edge facing the top main section edge of the secondary main section. Thereby, the first main section edge of the secondary main section 207 and the first pass door section edge of the secondary pass door section 204 face each other and are adjacent to each other. In the same way, the second main section edge of the secondary main section 207 and the second pass door section edge of the secondary pass door section 204 face each other and are adjacent to each other. In the same way, the top main section edge of the secondary main section 207 and the top pass door section edge of the secondary pass door section 204 face each other and are adjacent to each other. In the sectional door shown in Figure 1, the first main section edge of the secondary main section 207 and the first pass door section edge of the secondary pass door section 204 are on the right side of the pass door as seen from the outside of the sectional door. The second main section edge of the secondary main section 207 and the second pass door section edge of the secondary pass door section 204 are on the left side of the pass door. The top main section edge of the secondary main section 207 and the top pass door section edge of the secondary pass door section 204 are on the upper side of the pass door. Turning to Figure 2, the sectional door leaf 1 comprises a bottom profile 230. The bottom profile 230 is mounted to a bottommost horizontal section 11, i.e. a bottommost horizontal section 11 of the plurality of horizontal sections 11, 12, 13 of the sectional door leaf 1. Typically the bottom profile 230 may be in aluminium or steel, preferably aluminium. The bottommost section 11 is a horizontal primary section, i.e. a section comprising a primary pass door section 201. Said primary pass door section 201 is a bottommost primary pass door section 201. Accordingly, the bottom profile 230 may be mounted to a first main section 101 and a second main section 104 of the horizontal primary section 11. As previously described, the sectional door leaf 1 may be a sectional door leaf without a pass door. Hence, in one embodiment, the sectional door leaf 1 may comprise a plurality of horizontal sections 11, 12, 13, 14. Each of the horizontal sections extends horizontally to cover the opening when the sectional door leaf is in the vertical closed position. With reference to Figure 3a-b, the bottom profile 230 is arranged to come into contact with the floor of the opening in which the sectional door system is provided when the sectional door leaf 1 is in the vertical closed position. Figure 3a depicts a bottommost horizontal section without a pass door, when the sectional door leaf is in the vertical closed position. If the sectional door leaf has a pass door, the depicted bottommost horizontal section may be considered a first or section main section 101, 104. If the sectional door leaf do not have a pass door, the depicted bottommost horizontal section may be considered a horizontal section 11, said horizontal section 11 being a continuous section.

Referencing Figure 4 which in more detail depicts the highlighted section A in Figure 3a, the bottom profile 230 further comprises a threshold insulating arrangement 280 comprising at least one strip 281, 282 in a low heat conductivity material, i.e. a material configured to provide a lower level of heat transfer compared to the material of the bottom profile, arranged in a channel 283 extending along the bottom profile 230. The at least one strip may extend along the entire bottom profile 230 or only a portion thereof. The at least one strip may be a continuous strip or may comprise a plurality of separate sections.

This reduces the risk for freezing or forming of ice on the inside of the sectional door leaf due to heat transfer through the door.

The skilled person recognized that a number of low heat conductivity materials may be suitable for the at least one strip of the insulating arrangement. In one embodiment, the at least one strip may be made of polyamide (nylon). Preferably the at least one strip may be made of PA66.

The insulating arrangement 280 may comprise a first strip 281 and a second strip 282. The first and second strip is in a low heat conductivity material. Said first and second strip extends parallel and at a distance from each other along the bottom profile 230. The first strip 281 is mounted adjacent to a first inner surface of the channel 283.

The second strip 282 is mounted adjacent to a second inner surface of the channel 283. The first inner surface is opposite to the second inner surface.

In one embodiment, the first strip first inner surface is a bottom inner surface of the channel 283, whereby the second strip 282 is a top inner surface of the channel 283. Top and bottom herein refers to a position in relation to the sectional door leaf 1 when said sectional door leaf 1 is in the vertical closed position.

The insulating arrangement will be described in more detail further one with reference to Figure 6.

Again referencing Figure 4, the bottom profile 230 may comprise a stabilizing portion 221. The stabilizing portion protrudes from the inner door surface of the sectional door leaf 1, i.e. an inner surface of the bottommost horizontal section 11 in alignment with the inner door surface, in a stabilizing direction. The stabilizing direction is perpendicular to the vertical plane formed by the inner door surface when the sectional door leaf 1 is in the vertical closed position. Said stabilizing portion may be substantially parallel to the horizontal guide track section.

Sectional door systems are often utilized to cover large openings. Hence, they are subjected to large wind loads. Such wind loads causes may cause bending and other structural defects. The stabilizing portion allows for supporting of the pass door in order to mitigate bending or warping due to the wind load.

The bottom profile 230 may be provided with one or more bottom profile flaps 223, 224, 225. The one or more bottom profile flaps 223, 224, 225 may be in a low heat conductivity material. Each of the one or more bottom profile flaps may extend along the bottom profile 230. Further, each of the one or more bottom profile flaps 223, 224, 225 may protrude from a bottom surface of the bottom profile 230. Worded differently, the one or more flaps 223, 224, 225 may be arranged to come into contact with the floor of the opening when the sectional door leaf 1 is in the vertical closed position.

Said at least one bottom profile flap allows for less heat transfer through the door and further provides sealing between the floor and the bottom profile. The at least one bottom profile flap is preferably in a resilient material.

The at least one bottom profile flap may be in any low heat conductivity material. Preferably, said at least one bottom profile flap may be made of polyamide (nylon). Preferably, the at least one bottom profile flap may be made of PA66.

Each of the one or more bottom profile flaps 223, 224, 225 may be fitted into a respective bottom profile flap track. The one or more bottom profile flap track extends along the bottom profile 230. This allows for a less cumbersome and secure mounting of the bottom profile flap(s).

The one or more bottom profile flaps 223, 224, 225 may further comprise a retention part for securing said bottom profile flaps to the bottom profile flap track. The retention part may further comprise an aperture extending along and through said retention part. Further referencing Figure 4, the sectional door leaf 1 may further comprise a panel insulating strip 273. The panel insulating strip 273 is in a low heat conductivity material, i.e. a material configured to transfer less heat compared to the bottom profile 230. The panel insulating strip 273 extends along the bottommost section 11. If the sectional door has a pass door, said bottommost section 11 may be the first or second main section 101, 104 of said bottommost section 11. The panel insulating strip 273 will be further described with reference to Figure 7.

As further depicted in Figure 4, a first bottom profile strip 224 may be disposed adjacent to an outer surface of the sectional door blade 1, i.e. the outer surface of the bottommost horizontal section 11 which is in alignment with outer door surface. A second bottom profile strip 225 may be disposed adjacent to the inner surface of the sectional door leaf 1, i.e. the inner surface of the bottommost horizontal section 11.

In one embodiment, a third bottom profile strip 223 is disposed adjacent to the outer edge 229 of the stabilizing portion 221. Figure 5 discloses a cross-section view of the highlighted section B of Figure 3b.

In the depicted embodiment, the sectional door leaf comprises a pass door 2. The pass door 2 is arranged in a pass door opening of the sectional door leaf 1. The bottom profile 230 defines a bottom edge of the pass door opening.

According to said embodiment, the sectional door leaf 1 may further comprise a pass door bottom profile 270. The pass door bottom profile 270 is mounted to a bottom surface of the pass door 2, i.e. to a bottommost primary pass door section 201. Said bottom surface of the pass door 2 faces the floor of the opening when the sectional door leaf 1 is in the vertical closed position.

The pass door bottom profile 270 extends along the bottom surface of the pass door 2. In other words, the pass door bottom profile 270 may extend along the bottommost primary pass door section 201 or along the width of pass door 2.

At least a section of the panel insulating strip 273 may be mounted to the pass door bottom profile 270 and may extend along the bottom edge of the pass door opening. In one embodiment, the entire length of the panel insulating strip 273 may be mounted to the pass door bottom profile 270. In one embodiment, one section, i.e. a separate section of the panel insulating strip 273 may be mounted to the pass door bottom profile 270 and another section be mounted to the bottom profile 230.

As previously mentioned, the panel insulating strip 273 may be in any low heat conductivity material. Preferably, the bottom pass door strip may be made of polyamide (nylon). More preferably, the bottom pass door strip may be made of PA66.

As will be further described later on with reference to Figure 7, at least a section of the panel insulating strip 273 may be mounted to the pass door bottom profile 270. Said section extending along the bottom edge of the pass door opening.

In one embodiment, the panel insulating strip 273 may extend only along the bottom edge pass door opening. Thus, the entire length of the panel insulating strip 273 may be mounted to the pass door bottom profile 270.

In one embodiment, the panel insulating strip may comprise multiple separate sections. A section of the panel insulating strip 273 may thus be mounted to the bottom pass door profile 270. Another section of the panel insulating strip 273 may be mounted to the bottom profile 230 on a first side of the pass door opening, i.e. a right side of the pass door opening. Said section of the panel insulating strip 273 may be mounted to the bottom profile 230 adjacent and along the bottom surface of the first main section 101. The bottom surface is herein defined as the surface facing the floor of the opening when the sectional door leaf is in the closed position.

Yet another section of the panel insulating strip 273 may be mounted to the bottom profile 230 on a second side of the pass door opening, i.e. a left side of the pass door opening. Said section of the panel insulating strip 273 may be mounted to the bottom profile 230 adjacent and along the bottom surface of the second main section 104. The bottom surface is herein defined as the surface facing the floor of the opening when the sectional door leaf is in the closed position.

Said sections may be aligned to extend along the bottommost section 11, i.e. adjacent to the bottom surface. The bottom surface is herein seen as the surface of the sectional door leaf facing the floor when the sectional door leaf is in the vertical closed position of the sectional door leaf. Thus, referencing Figure 3-5, to allow for the alignment of the different sections and also provide sufficient room for the closing of the pass door leaf the bottom profile has a sunken threshold portion 220. Said threshold portion 220 of the bottom profile 230 forms the bottom edge of the pass door opening. The threshold portion 220 is arranged to provide a gap between the pass door bottom profile 270 and the top surface of said threshold portion 220. Preferably, said gap is between 8 and 17 mm. More preferably, the gap is between 9 and 14 mm, and most preferably 12 mm.

Again referencing Figure 5, the pass door bottom profile 270 may further comprise a pass door flange 271. The upper flange 271 extends along the pass door bottom profile 270. The upper flange 271 extends parallel and adjacent to the pass door 2 along the outer door surface.

The pass door flange 271 may comprise a recess 272. The recess 272 extends along the upper flange 271. The recess 272 is at least partially filled with an insulating material. Thus the heat transfer through the pass door is further reduced. The pass door bottom profile 270 may comprise a pass door frame flange 278.

The bottom profile 230 has an outer edge 229. The outer edge 229 is substantially aligned with the vertical plane formed by the outer door surface when the sectional door leaf 1 is in the vertical closed position such that the outer edge 229 is adjacent to the pass door frame flange 278 when the pass door 2 is in a closed position. The pass door bottom profile 270 is provided with a pass door frame insulating strip 310. The pass door frame insulating strip 310 is arranged to be in contact with the outer edge 229 of the bottom profile 230 and the pass door frame flange 278 when the pass door 2 is in the closed position.

The pass door frame insulating strip 310 may comprise a main portion 311 mounted to the pass door bottom profile 270. Said main portion 311 may further extend along the pass door frame flange 278.

The pass door frame insulating strip 310 may comprise a first sealing arm 312.

The first sealing arm extends away from the pass door frame flange 278 to come into contact with the outer edge 229 of the bottom profile 230 when the pass door 2 is in the closed position. The pass door frame insulating strip 310 may further comprise a second sealing arm 313. The second sealing arm 313 extends away from the pass door frame flange 278 and downwardly to come into contact with a top surface of the bottom profile 230 when the pass door 2 is in the closed position.

As depicted in Figure 5, the stabilizing portion 221 may be substantially wedge- shaped with an upper inclined surface. The upper inclined surface may be tapered in the stabilizing direction. This enables a low threshold without comprising the stability and wind load resistance of the sectional door leaf. This is particularly advantageous when the sectional door leaf comprises a pass door due the pass door opening effectively reducing the capability for the sectional door leaf to accommodate load. However, it is noted that the tapered design of the stabilizing portion may be implemented in a sectional door leaf without a pass door as well.

Figure 6 shows a more detailed cross-section view of the threshold insulating arrangement. The at least one strip 281, 282 has an intermediate bent portion 2811, 281 and a first and second retention member 2814, 2815, 2824, 2825. The intermediate bent portion 2811, 2821 may extend between the first and second retention member. The channel 283 may accordingly be provided with retention portions corresponding to said first and second retention member for securing the at least one strip 281, 282 in the channel.

As shown in Figure 6, two strips may be utilized. Accordingly, the first strip 281 has an intermediate bent portion 2811 and a first and second retention member 2814, 2815. The intermediate bent portion 2811 extends between the first and second retention member 2814, 2815. The channel 283 is provided with retention portions corresponding to the first and second retention member for securing the first strip 281 in the channel 283. Similarly, the second strip 282 has an intermediate bent portion 2821 and a first and second retention member 2824, 2825. The intermediate bent portion 2821 extends between the first and second retention member 2824, 2825. The channel 283 is provided with retention portions corresponding to the first and second retention member for securing the second strip 282 in the channel 283.

An intermediate bent portion as defined herein may be considered a protruding portion which protrudes from a plane defined by the first and second retention member. As previously discussed, the first and second inner surface of the channel 283 may be a top and bottom inner surface of the channel 283. Again referring to Figure 6, the channel 283 comprises a top aperture 2832 extending through the top surface of the bottom profile 230. Further, the channel 283 comprises a bottom aperture 2831 extending through the bottom surface of the bottom profile.

The intermediate bent portion 2811 of the first strip 281 is arranged to be fitted into the bottom aperture 2831. The intermediate bent portion 2821 is arranged to be fitted into the top aperture 2832.

This allows for an insulating arrangement which is easier to mount and less susceptible to wear and tear. Further, the gap between in the channel between the strips further decreases the heat exchange between the pass door and the threshold portion. The outer edge of the intermediate bent portion 2811 of the first strip 281 may be substantially flush with the bottom surface of the bottom profile 230. The outer edge of the intermediate bent portion of the second strip 282 may be substantially flush with the top surface of the bottom profile 230. This creates a substantially bottom surface in the doorway for the pass door, reducing the risk for accumulation of water, dirt etc. while still allowing for easy installation of the insulating arrangement.

The intermediate bent portions 2811, 2821 of the first and second strip 281, 282 may accordingly have planar outer edges.

In one embodiment, the intermediate bent section 2811 of the first strip 281 may comprise a horizontal portion having the outer edge flush with the bottom surface of the bottom profile 230. The intermediate bent section 2811 further comprises a first inclined section 2812 and a second inclined section 2813.

The intermediate bent section 2821 of the second strip 282 may comprise a horizontal portion, said horizontal portion having the outer edge flush with the top surface of the bottom profile 230. The intermediate bent section 2821 further comprises a first inclined section 2822 and a second inclined section 2823. The first inclined section 2822 connects the first retention member 2824 and the horizontal portion. The second inclined section 2822 connects the second retention member 2825 and the horizontal portion. Figure 7 depicts a cross-section view of the panel insulating strip 273.

In one embodiment, the panel insulating strip 273 may have a hollow cross- section. Further, the panel insulating strip 273 may comprise a delimiting flange 276. Said delimiting flange 276 forms a pair of chambers along the panel insulating strip 273. The delimiting flange allows a stiffer strip which is easier to mount and more durable. Further the air trapped in the aforementioned chambers further reduces the heat transfer through the sectional door system.

As described with reference to Figure 4, at least a section of the panel insulating strip 273 may be mounted to the bottom profile 230. Accordingly, the bottom profile 230 may comprise a panel insulating strip track 2733'. The section of the panel insulating strip 273 mounted to the bottom profile 230 is fitted into said panel insulating strip track 2733'. The bottom profile 230 comprises a top recess 2737' arranged to receive a top portion 2732' of the section of panel insulating strip 273 mounted to the bottom profile 230. The bottom profile 230 comprises a bottom recess 2731 ' arranged to receive a bottom portion 2736' of the section of the panel insulating strip 273 mounted to the bottom profile 230.

The top edge of the top portion 2732' is essentially flush with a top surface of the bottom profile 230 and the bottom edge of the bottom portion 2731 ' forms an upper inner surface of the aperture 292. As described with reference to Figure 5, at least a section of the insulating strip

273 may be mounted to the pass door bottom profile 270.

Referencing Figure 8, the pass door 2 is pivotally mounted by means of pass door hinges 621. Thus, the one or more 201, 202, 203 primary pass door sections may be pivotally connected to the first or second main sections by means of said pass door hinges 621. In the depicted example, the primary pass door sections 201, 202, 203 are connected to the first main sections 101, 102, 103 by means of the pass door hinges 621.

Hence, the panel insulating strip mounted to the bottom profile may be considered a bottom panel insulating strip. Similarly, the left vertical, right vertical and/or the top pass door profiles may have panel insulating strips 273 mounted thereto as well. This may be achieved in a similar manner to what was described with reference to Figure 5 and 7. Accordingly, a left panel insulating strip 273 of the pass door 2 may be mounted to the left vertical door profile 570, a right panel insulating strip 273 of the pass door 2 may mounted to the right vertical door profile and a top panel insulating strip 273 of the pass door 2 may be mounted to the top door profile.

The third profile element 631 and the fourth profile element 632 may be mounted to the section 12, 13, 14 by means of rivets.

Figure 10a discloses a cross-section view of the section arrangement. The highlighted sections A and B are depicted in closer detail in Figure lOb-c. Referencing said figures, at least one of the first profile element 531 and the second profile element 52 may comprise an insulating arrangement 280. The insulating arrangement 280 may correspond to the insulating arrangement 280 previously described with reference to Figure 3-6.

The insulating arrangement 280 comprises at least one strip 281, 282. The at least one strip 281, 282 is in a low heat conductivity material. The at least one strip 281, 282 is arranged in a channel 283. The channel 283 extends along the at least one of the first profile element 531 and the second profile element 532.

Similar to the insulating arrangement in the bottom profile previously described, this reduces the risk for freezing or forming of ice on the inside of the sectional door leaf due to heat transfer through the door, i.e. between the sections of the sectional door. As previously described, the skilled person recognized that a number of low heat conductivity materials may be suitable for the at least one strip of the insulating arrangement. In one embodiment, the at least one strip may be made of polyamide (nylon). Preferably, the at least one strip may be made of PA66.

In one embodiment, the channel 283 is in the form of a recess extending through the first and/or second profile element.

The insulating arrangement 280 may comprise a first and second strip 281, 282. Both the first and second strip 281, 282 may be in a low heat conductivity material. The first and second strip 281, 282 extend parallel and at a distance from each other along the at least one of the first profile element 531 and the second profile element 532. The first strip 281 is mounted adjacent to a first inner surface of the channel 283. The second strip 282 is mounted adjacent to a second inner surface of the channel 283. The first inner surface is opposite to the second inner surface. Accordingly, the first and second strip are mounted at a distance from each other on opposite inner sides of the channel. Thereby, an insulated chamber is achieved, further mitigating heat transfer through the door.

Accordingly, the channel 283 may form a sealed chamber. This is achieved by means of the first and second strip 281, 282.

The insulating arrangement 280 and the at least one strip 281, 282 arranged in the channel of the first and/or second profile is previously depicted in Figure 7. Referencing back to Figure 6 in conjunction with Figure lOb-c, the at least one strip 281, 282 accordingly has an intermediate bent portion 2811, 2821. The at least one strip 281, 282 further has a first and second retention member 2814, 2815, 2824, 2825. The intermediate bent portion 2811, 2821 extends between the first and second retention member 2814, 2815, 2824, 2825. Thus, the channel 283 extending along the first and/or second profile element is provided with retention portions corresponding to the first and second retention member for securing the at least one strip 281, 282 in the channel 283. Thus, the strips may be arranged in a simple and time-efficient manner since no fastenings elements are required to fixate the strips. Instead the resilient properties of the material causes the fixation of the strips.

Further referencing back to Figure 6 in conjunction with Figure lOb-c, the channel 283 may comprise a first aperture 2832. The first aperture 2832 extends through the first inner surface of the at least one of the first profile element 531 and the second profile element 532. The channel 283 further comprises a second aperture 2831. The second aperture 2831 extends through the second inner surface of the at least one of the first profile element 531 and the second profile element 532. The intermediate bent portion of the first strip 281 is arranged to be fitted into the first aperture 2832. The intermediate bent portion of the second strip 282 is arranged to be fitted into the second aperture 2831.

The first aperture may extend from a first outer surface of the first profile element 531 and/or the second profile element 532 and into the channel through the first inner surface of said channel 283. Similarly, the second aperture may extend from a second outer surface of the first profile element 531 and/or the second profile element 532 and into the channel through the second inner surface of said channel 283. The first outer surface and the second outer surface are opposite sides.

In one embodiment, the outer edge of the intermediate bent portion 2811 of the first strip 281 is substantially flush with the first outer edge of the at least one of the first profile element 531 and the second profile element 532. The outer edge of the intermediate bent portion 2821 of the second strip 282 is substantially flush with the second outer edge of the at least one of the first profile element 531 and the second profile element 532. Thus, one of the strips of the first and/or second profile element will be close to the section of the section arrangement. The other of the strips of the first and/or second profile element will be close to an adjacent section arrangement of the sectional door leaf. Hence, the heat transfer between neighbouring section arrangements in the door is further mitigated.

In one embodiment, wherein the first profile element 351 is a top profile element and the second profile element 352 is a bottom profile element. Thus, the first and second inner surface of the channel 283 may be a top and bottom inner surface of the channel 283. The first aperture 2832 may thus be a top aperture extending through the top surface of the at least one of the top and bottom profile. The second aperture 2831 may thus be a bottom aperture extending through a bottom surface of the at least one of the top and bottom profile. The intermediate bent portion of the first and second strip 281, 282 may thus be arranged to be fitted into the top aperture and bottom aperture, respectively. Accordingly the intermediate bent portion of the first strip 281, i.e. top strip, is fitted into the first aperture, i.e. top aperture and the intermediate bent portion of the second strip 282, i.e. bottom strip, is fitted into the second aperture, i.e. bottom aperture.

Thus, the outer edge of the intermediate bent portion 2811, 2812 of the first and second strip 281, 282 is substantially flush with the top and bottom surface of the at least one of the top profile element 531 and the bottom profile element 532, respectively. As seen in Figure 10b, the section arrangement may further comprise a cover element 591. The cover element 591 is mounted to and extending along the first profile element 531. The cover element 591 may be adapted to cover at least a portion of the first profile element 531. The cover element 531 is further adapted to be proximal to an adjacent profile element mounted to an adjacent section 12, 13, 14 of the sectional door leaf 1.

Preferably, the cover element 591 at least partially covers an outer surface of the first profile element 531. Said outer surface may be a surface facing away from the section 12, 13, 14. Worded differently, the outer surface may be a surface of the first profile element 531 extending along the length of the first profile element 531 and being distant from the section 12, 13, 14. The outer surface may thus comprise the first aperture 2832. Accordingly, the cover element may be adapted to cover at least a portion of the first strip 281. The cover element may further adapted to cover at least a portion of the first aperture 2832.

In one embodiment, wherein the sectional door leaf comprises multiple section arrangements in accordance with the invention, the cover element 591 is adapted to be proximal to an adjacent profile element of an adjacent section arrangement.

The cover element increases the safety of the door to prevent pinching as well as provides additional insulation between the sections of the sectional door leaf.

The first profile element 531 may be a top profile element. The outer surface of the first profile element 531 may thus be a top surface.

In one embodiment, the cover element 591 is arranged to be mounted into an adjacent second profile element mounted to the adjacent section 12, 13, 14.

The cover element 591 comprises a curved portion 596. The curved portion 596 is adapted to be proximal to an adjacent profile element mounted to an adjacent section 12, 14, 14 of the sectional door leaf 1.

Preferably, the cover element 591 is made of a polymeric material which mitigates heat transfer through the door. In one embodiment, the cover element is made of ABS-plastic. ABS-plastic does not expand when subjected to moisture which safeguards the function of the door. In one embodiment, wherein the sectional door leaf comprises multiple section arrangements in accordance with the invention, the curved portion 596 is adapted to be proximal to an adjacent profile element of an adjacent section arrangement.

As depicted in Figure 10b, the first profile element 531 may comprise a first attachment flange 592 and a second attachment flange 593. A first end of the cover element 591 is attached to the first attachment flange 592 and a second end is attached to the second attachment flange 593. The first end being an opposite end of the cover element 591 to the second end.

The first profile element 531 may be attached to the attachment flanges by means of a snap connection. Thus the attachment flange has a portion onto which the cover element 591 is retained to. In one embodiment, the first attachment flange 592 is arranged at a lower position than the second attachment flange 593 such that the curved portion 596 of the cover element 591 extends between said first and second attachment flange.

The section arrangement may further comprise first profile fastening elements 571 arranged in the channel 283 of the first profile element 231 for attaching the first profile element 531 to the third profile element 631 and the fourth profile element 632.

The fastening elements 571 may be arranged in through-holes extending from the channel 283 and corresponding holes in the third profile element 631 and the fourth profile element 632. The fastening elements may extend in the direction of the third and fourth profile element.

In one embodiment, the first profile fastening elements may be screws.

The first profile element 531 may be attached to the section 12, 13, 14 by means of a snap-fit connection 541, 542.

Turning to Figure 10c, the second profile element 532 is depicted in more detail. The second profile element 532 may be a bottom profile element.

The second profile element 532 comprises a curved inner surface 599. The curved inner surface 599 is adapted to be proximal to a profile element of an adjacent section 12, 13, 14 of the sectional door leaf 1.

In one embodiment wherein the sectional door leaf 1 comprises a plurality of interconnected section arrangements, the curved inner surface 99 is adapted to be proximal to a curved surface of the cover element mounted to an adjacent profile element of an adjacent section arrangement.

To enable mounting to a sectional door leaf with multiple section arrangements, the curved portion 596 of the cover element 591 may have a corresponding curvature to the curved inner surface 599 of the second profile element 532.

The second profile element 532 comprises a first profile flange 518 and a second profile flange 517. The first and second profile flange extends along the second profile element 532, i.e. along the length of the first second profile element 532. The first and second profile flange extends parallel at a distance from each other such that a recess is obtained between them adapted to receive a profile element, i.e. first profile element of an adjacent section arrangement. Thus, the first and second profile flange are arranged to receive the cover element 591 of the adjacent profile between them.

An inner surface of the first profile flange 518 may comprise the curved inner surface 599. Thus, the curved inner surface 599 may face the second profile flange 517. The curved inner surface 599 is arranged to be proximal to the curved portion of the cover element 591 of an adjacent section arrangement.

The sealing strips 281, 282 and the channel 283 may be arranged in a profile section extending between the first profile flange 518 and the second profile flange 517.

The section arrangement may further comprise second profile fastening elements 572 arranged in the channel 283 of the second profile element 231 for attaching the second profile element 531 to the third profile element 631 and the fourth profile element 632.

The fastening elements 572 may be arranged in through-holes extending from the channel 283 and corresponding holes in the third profile element 631 and the fourth profile element 632. The fastening elements may extend in the direction of the third and fourth profile element.

The second profile element 532 may be attached to the section 12, 13, 14 by means of a snap-fit connection 541, 542.

Figures 11a depicts a side view of the section arrangement according to an embodiment. The highlighted zones A and B are further depicted in Figures 1 lb-c.

Referencing Figure 1 lb, the section arrangement may further comprise an insulating profile 582. The first profile element 531 may comprise an elongated recess 594 (as seen in Figure 9b). The elongated recess 594 is adapted to receive the insulating profile 582. The insulating profile 582 is arranged to come into contact with an adjacent profile element mounted to an adjacent section 12, 13, 14 of the sectional door leaf 1. Thus the insulating profile 582 is arranged to extend outwardly from the first profile element to come into contact with said adjacent section.

Again referencing Figure 1 lb, the section arrangement may further comprise an additional insulating strip 581 arranged on the first profile element 531. The insulating strip 581 may extend along the first profile element 531 at a distance from the insulating profile 582. Figure 11c depicts the highlighted zone B in Figure 11a in further detail. Referencing Figure 11c, the section arrangement may further comprise an insulating element 583. The second profile element 532 may further comprise an elongated recess 595.
