Reference [1] explains what is meant by sectional door. Reference [2] explains the term wicket door for a door integrated into a door leaf. A sectional door in finger protection design is known from reference [3], with door leaf elements (here in the form of sections formed from panels) of the door having a finger protection projection with a convex outer side on the upper edge in the closed position and a groove on the lower edge in the closed position, in the finger guard projection of the one below panel engages. Doors, in particular sectional doors, with a wicket door and a particularly low wicket door threshold are known from references [4] and [5]. The threshold is formed by a reinforcement arrangement that is more wide than tall. More details on garage doors designed as sectional doors, also with wicket doors, can be found in reference [6]. These gates have proven themselves in practice, as the door opening is easy to pass through with wheels, trolleys or wheelchairs due to the low threshold. However, there are also installation situations where such doors are less suitable. In particular, the wicket door could not easily be opened to the outside when the floor rises in front of the door opening. From references [7] to [9] different threshold designs of pass doors of gates are known, which are complicated and expensive to manufacture and assemble.

The invention has set itself the task of providing a door with a wicket door that is suitable for installation with a sloping floor structure and can be produced with low production costs and less manufacturing effort and still offers an attractive appearance.

To solve this problem, the invention provides a door according to claim 1.

Advantageous configurations are the subject matter of the dependent claims.

The invention creates a door with a door leaf that can be moved between an open position and a closed position that closes a door opening and has a plurality of door leaf elements, each of which has a panel and can be tilted relative to one another with respect to tilting axes that run parallel to one another, and a door that is integrated in the door leaf and has a door leaf which, in its closed position, is accommodated in a door recess in the door leaf and can be pivoted relative to the door leaf elements about a pivot axis running essentially perpendicularly to the tilting axes, with a lower region of the door recess in the closed position of the door leaf being delimited by a threshold is whose upper edge in the closed position of the door leaf from a lower limit of the door opening measured has a distance SH in the range of 40 mm ≤ SH ≤ 120 mm, with the threshold seen in cross section being formed by a lower edge area of the panel of the bottom door leaf element, a reinforcement strip and a threshold cover strip, with the reinforcement strip being designed as a one-piece profile strip and itself extends essentially over the entire lower edge area of the panel of the bottom door leaf element and has a fastening profile area for contact with an inner side of the lower edge area of the panel and for fastening there, an engagement profile area for engaging in a groove on the underside of the panel and a reinforcing rib profile area for stiffening, which extends away from the fastening profile area, wherein the sill cover strip is designed to cover an upper side and lower edge area of the panel in the area of the sill and is fastened to the fastening profile area.

It is preferable that the reinforcing rib profile portion is tubular.

It is preferred that the reinforcing rib profile area encloses an elongate cavity.

It is preferred that the reinforcing rib profile area extends away from the fastening profile area essentially perpendicularly to a contact surface of the fastening profile area.

It is preferred that the fastening profile area extends over the entire inner side of the lower edge area of the panel.

It is preferred that the fastening profile area has a contact surface for abutting over a large area on the inside of the lower edge area of the panel.

It is preferred that the fastening profile area is fastened to the lower edge area of the panel by means of a plurality of screw fasteners which are provided at a distance from one another over the width of the door leaf.

It is preferred that the engagement profile area is essentially tubular.

It is preferred that the engagement profile area is formed in accordance with the inner contour of the groove.

It is preferable that the engaging profile portion abuts the entire inside of the groove.

It is preferred that the groove is a finger protection groove formed complementarily to a fingerprint projection.

It is preferred that the engagement profile portion has a seal recess to which a lower door seal is attached.

It is preferred that the threshold cover strip is designed as a one-piece profile strip. The threshold cover strip is preferably designed essentially in the form of a U-profile.

It is preferred that the threshold cover strip has a contact leg that extends parallel to the fastening profile area and bears against it.

It is preferred that fasteners, by means of which the fastening profile area is attached to the lower edge area of the panel, reach through the threshold cover strip.

It is preferred that the sill cover strip and the reinforcement strip are formed of metal. It is preferred that the threshold cover strip and the reinforcement strip are designed as extruded profiles, in particular made of metal, more particularly of light metal and most preferably of an aluminum alloy.

It is preferred that the reinforcing bar carries a closing edge gate seal of the gate.

It is preferred that the door seal is attached to the engaging profile portion.

The door is preferably a sectional door with a wicket door. The door leaf elements preferably have panels designed to protect against fingers. In particular, the panels are designed as described and shown in reference [3].

The door installation situation often has a sloping floor structure. Conventional threshold profiles or those that are standard according to [6] cannot always compensate for such a sloping floor structure within the threshold height SH. This is counteracted with preferred refinements of the invention, with a reduction in the production costs and a reduction in the production effort also being achieved.

Preferably, the threshold height SH, i.e. the distance between the upper edge of the threshold of the door recess in the door leaf when the door leaf is in the closed position and the lower limit of the door opening, i.e. in particular the floor, is 70 mm ≤ SH ≤ 100 mm, more preferably 75 mm≦SH≦95 mm, particularly preferably 80 mm≦SH≦90 mm. In the case of particularly preferred doors, SH=85 mm.

In order to keep the production outlay and production costs low and still provide an attractive appearance on the outside, the lower edge area of the lowest panel is used to form the point. For example, when cutting out the door recess for the wicket door, a lower portion of the bottom panel is left.

This lower edge area of the bottom panel is further reinforced by a multi-part stiffening arrangement or reinforcement arrangement.

The stiffening assembly includes a reinforcement bar and a sill cover bar. As the term "bar" already expresses, the reinforcing bar is designed in one piece as a bar. The reinforcing strip is designed as a one-piece profile element with a number of profile areas.

On the one hand, the left lower edge area of the bottom panel is reinforced by a reinforcement strip, which extends over a larger area of the door leaf width than the width of the door recess and is fastened to the bottom panel.

The stiffening effect of the reinforcement bar is provided on the one hand by the fact that the reinforcement bar rests with a fastening profile area on the inside of the edge area of the lower panel and is thus fastened by means of fasteners, such as screws in particular, which are preferably distributed at regular intervals across the width of the door leaf, and on the other hand is provided with several reinforcing profile areas.

A first reinforcing profile area forms a stiffening rib. This is preferably tubular and thus on the one hand light and yet stable. This reinforcing rib profile area preferably extends essentially perpendicularly away from the fastening profile area, in particular when the door leaf is in the vertical position in the closed position, in a horizontal direction into the interior of the space to be closed. The cavity enclosed by the stiffening rib profile area is preferably elongate. A free end of the stiffening rib profile area is preferably rounded.

A groove on the underside of the lowest panel is preferably used to accommodate a second reinforcing profile area, in particular the groove which, when the panel is used in higher door leaf elements, serves to accommodate the finger protection projection of the door leaf element located below. The second reinforcing profile area is designed as an engaging profile area for engaging in the groove. The engagement profile area is preferably adapted to the contour of the groove, so that it bears against the bottom of the groove everywhere. Thus, a safer Form fit between reinforcement profile and panel achieved. The engagement profile area is preferably designed as a hollow profile and more preferably tubular except for an opening for fastening the door sealing profile.

As a further part of the reinforcement arrangement, a threshold covering strip designed as a threshold covering profile is provided. This threshold cover profile, which is also designed as a one-piece profile element with several profile areas, covers the upper side of the left lower edge area of the lowest panel, so that protection of the threshold and an attractive appearance are achieved in a simple manner. The threshold cover profile is stiffened in that it is designed as an angle profile, U-profile or C-profile with several legs. A simple assembly and fastening with a simultaneous increase in the stiffening effect can be achieved if one of the legs bears against the fastening profile area and is fastened together with this to the bottom panel. Thus, the same fasteners can be used to easily attach the multiple parts of the reinforcement assembly.

The reinforcement strip preferably forms a threshold profile, in particular made of aluminum, which provides a guide for the door seal on the closing edge of the door and also contributes to the slat reinforcement of the lower door slat.

In the Figures 1 to 4 different views of a door 10 with a door leaf 12 and a door 14 integrated in the door leaf 12 are shown.

The door leaf 12 can be moved between an open position and a closed position shown in the figures. In the closed position, the door leaf closes a door opening 16, with a floor 18 forming a lower boundary 20 of the door opening.

The door leaf 12 has several door leaf elements 22.1-22.4, with a bottom door leaf element 22.1 having a closing edge 24, with a door seal 26 on the closing edge 24 for sealing the door leaf 12 relative to the floor 18 in the closed position shown.

The door leaf elements 22.1-22.4 can be tilted relative to one another with respect to tilting axes 28 running parallel to one another.

The door 10 is designed in particular as a sectional door 30 with a guide 32 for the door leaf 12 . Such sectional doors 30 and guides 32 are known in principle from references [1], [3] to [6], so that reference is made to these references for further details on the possible designs of the guide.

The individual door leaf elements 22.1-22-4 are essentially formed by panels designed to protect against fingers, as is described and shown in more detail in references [3] and [6]. Reference is made to reference [6] for further details on the construction and possible materials of the panels.

Accordingly, the panels 34 have a finger guard projection 36 at their upper end and a groove 38 complementary to the finger guard projection 36 for receiving the finger guard projection 36 of the underlying panel 34 at their lower end. Reference [3] is referred to for further details on the design of the finger protection projection 36 and the groove 38 .

The door 14 integrated into the door leaf 12 forms a pass door. The door 14 has a door panel 40 which, in its closed position, is accommodated in a door recess 42 in the door panel 12 and is preferably aligned flush with the door panel 12 in the closed position. The door leaf 40 can be pivoted relative to the door leaf elements 22.1-22.4 from the illustrated closed position into an open position about a pivot axis 44 running essentially perpendicularly to the tilting axes 28. In the illustrated embodiments the door leaf 40 can be pivoted outwards in its open position. In this way, the space to be closed can be better utilized directly behind the closed door leaf 12 . For example, a vehicle can be parked without impairing the ability of the door 14 to be opened.

The door recess 42 is delimited at its lower region by a sill 46, which can also be referred to as a wicket door sill.

Like in particular figure 3 As can be seen, the floor 18 rises in front of the door opening 16 to form a ramp 48. The line 49 indicates the plane in which the lower end of the door panel 40 moves when the door 14 is opened. The threshold 46 has a threshold height SH in the range of 40 mm≦SH≦120 mm so that the door leaf 40 does not hit the ramp 48 even when it is fully open, even if the latter rises at a large angle of incline. In the illustrated embodiments, the threshold height is 85 mm; other threshold heights around 85 mm are of course also possible. The distance between the upper edge 50 of the sill 46 and the lower boundary 20 of the door opening 16 when the door leaf 12 is in the closed position is defined as the threshold height SH.

the Figures 3 and 4 as well as the partial figure on the far right in figure 5 show sections through the gate 10 in the region of the threshold 46. As can be seen therefrom, the gate leaf 12 has a stiffening arrangement 52 formed from several parts. The threshold 46 is formed by a lower edge region 54 of the panel 34 of the bottom door leaf element 22.1 and the stiffening arrangement 52. In addition, the gate seal 26 is provided.

The stiffening assembly 52 includes a reinforcement bar 56 and a sill cover bar 58 . Both the reinforcement strip 56 and the threshold cover strip 58 are designed as a one-piece profile element, ie a one-piece strip with a specific cross-sectional profile. The reinforcing strip 56 is thus a part of the multi-piece stiffening assembly 52, and the sill cover strip 58 is another part of the multi-piece stiffening assembly 52.

The reinforcing strip 56 is in. together with the gate seal 26 in figure 6 and alone in the figures 7 and 8th shown.

The reinforcement strip 56 extends essentially over the entire width of the bottom door leaf element 22.1. How from the Figures 6 to 8 As can be seen, the reinforcement strip 56 is produced as a profile strip from a metal material, in particular a light metal such as aluminum or an aluminum alloy. In particular, the reinforcing bar 56 is extruded.

The reinforcing strip 56 has a fastening profile area 60, an engaging profile area 62, a reinforcing rib profile area 64 and a connecting profile area 66.

The reinforcement strip 56 is formed in particular from a metal with a wall thickness in the range from 1 mm to 4 mm, in particular 2 mm.

The fastening profile area 60 is as shown in FIG Figure 3, Figure 4 and the right representation in figure 5 as can be seen, designed to rest on an inner side 68 of the lower edge region 54 of the panel 34 of the lowermost door leaf element 22.1 and to be fastened there.

Like in particular figure 7 As can be seen, the fastening profile area 60 has a contact surface 70 which bears against this inner side 68 over its entire surface. The fastening profile area 60 is in particular flat and has a rectangular shape in cross section. The fastening profile area 60 extends essentially over the entire inner side of the lower edge area 54 which forms the sill 46 .

The reinforcing rib profile area 64 forms a reinforcing rib or reinforcement rib for reinforcing the lower edge area 54 of the bottom door leaf element 22.1. The reinforcing rib profile area 64 forms a partial hollow profile of the reinforcing strip 56 and is in particular angular, U-shaped, bridge-shaped or, as shown, tubular. Of the Reinforcing rib profile area 64 encloses an elongate cavity 72. In the exemplary embodiment illustrated, the reinforcing rib profile area 64 extends away from the fastening profile area 60 transversely to the main plane of the lowest door leaf element 22.1. The reinforcing rib profile area 64 thus extends in the horizontal direction in the illustrated closed position of the door leaf 12, where the door leaf 12 and thus also its door leaf element 22.1-22.4 are aligned in the vertical plane.

The reinforcement bar 56 is arranged on the inside of the door leaf 12 . The reinforcing rib profile area 64 extends into the interior of the space to be closed by the door leaf 12 . At the free end 74, the reinforcing rib profile area 64 is rounded in a circular, elliptical or oval shape.

The engaging profile portion 62 is formed in accordance with the inner contour of the groove 38 and is, as is best from the Figures 3, 4 and 5 (right illustration) can be seen, on the entire area of the groove 38 on the panel 34. Corresponding to the design of the groove 38, the engaging profile area 62 has an L-angled area 76 and, adjoining it, a convex area 78, which is formed by a polygonal shape with rounded edges. Furthermore, the engagement profile area 62 has flanges 80 on the underside that are directed toward one another, which leave a slot between them as a sealing recess 82, to which locking element profile areas 84 of the door seal 26 are attached in order to attach the door seal 26 to the reinforcement strip 56. Due to the L-angled area 76, the convex area 78 and the flanges 80, the engaging profile area 62 also forms a further partial hollow profile of the reinforcing strip 56, which is of almost closed tubular design except for the sealing recess.

The panels 34 are chamfered at their lower inner edge in order to receive corresponding parts of hinges, not shown, for forming the pivot axes 28 here. The connection profile area 66 connects the Fastening profile area 60 with the engaging profile area 62 and is formed according to this contour of the inner lower edge of the panel 34 bevelled.

Transitions and edges between the profile areas 60, 62, 64, 66, 76, 78, 80 of the reinforcing strip 56 are rounded with radii R that are sometimes different.

figure 8 shows the visible surfaces 86, which can be seen when the reinforcement strip 56 is installed.

The threshold cover strip 58 is in figure 4 and right in figure 5 mounted and in the figures 9 and 10 shown alone in cross section.

The threshold cover strip 58 is also designed as a profile strip made of a metal, in particular light metal and more particularly aluminum material.

In the illustrated embodiment, the cross section of the sill cover strip 58 is essentially U-shaped with an outer leg 88, an inner leg 90 and a web 92 connecting the legs 88, 90.

The threshold cover strip 58 is designed with a wall thickness that is comparable to the wall thickness of the reinforcement strip 56. For example, the wall thickness is between 1 mm and 4 mm and in particular 2 mm.

The legs 88, 90 are of different lengths.

The inner leg 90 forms a contact leg 94 which rests against the fastening profile area 60 of the reinforcement strip 56 in the assembled state. The profile areas of the reinforcement strip 56 and the threshold cover strip 58 lying one on top of the other can be fastened to the lower edge area 54 together with fasteners 96 which pass through both profile areas.

In the embodiment shown, the fasteners 96 are selected according to the material of the panel 34 . These are in evenly spaced across the width of the gate 10 is provided. In the area of the sill 46, these fasteners 96 pass through the sill cover strip 58 and the reinforcement strip 56, as shown, and thus fasten both parts of the stiffening arrangement 52 in the area of the sill 46 to the lower edge region 54 of the panel 34.

The outer leg 88 bears against the lower edge region 54 of the panel 34 on an outer side 98 . The web 92 forms the upper edge 50 of the sill 46 and protects the upper end of the lower edge region 54 of the panel 34.

In addition, the threshold cover strip 58 will cover the in figure 10 indicated visually appealing visible surface 86 provided.

The sill cover strip 58 extends over the entire lower area of the door recess 42 and thus over the entire width of the sill 46.

The door shown here is designed in particular as special equipment for doors 10 from a door series that can be supplied with or without wicket doors and, if designed with wicket doors, with different threshold heights SH. figure 5 shows a compilation of different versions of such a door series, with a series version of door 10 with a wicket door and a low threshold with a maximum threshold height SH0 of 10 mm being shown on the far left, in the middle a design of door 10 with a wicket door and a threshold height SH1 of 33 5 mm is shown and on the far right the embodiment according to the invention with a height of the threshold SH in the wicket door of 85 mm is shown. The middle and right-hand version can be optionally selected. The embodiments presented here deal with the construction of the corresponding highest sleeper height SH.

As can be seen from the different constructions, the door leaves 40 are also designed differently in their lower area in the case of the different deliverable wicket doors with different threshold heights. In the embodiment shown on the far right, which is an embodiment of the Invention represents the underside of the door leaf 40 is formed with a door leaf profile 100, which is formed substantially U-shaped to encompass and stiffen the lower edge.

The door leaf profile 100 accordingly has a short outer leg 102 , a long inner leg 104 and a connecting web 106

In the area of the outer leg 102 , a downward-reaching stop strip 108 is formed on the door leaf profile 100 , which, possibly provided with a stop sealing profile 110 , strikes the outer leg 88 of the threshold covering strip 58 when the door 14 is closed. Furthermore, a sealing lip profile 112 can be provided on the door leaf profile 100 in the area of the inside 68 as a further door seal for the door 14 .

Reference is made to references [3] to [6] for further details of the gate that are not shown or explained in more detail here.

Some aspects of the gate are summarized again below:
