TITLE
DOOR OR WINDOW SEAL BARRIER FOR ANIMALS TECHNICAL FIELD
The disclosure relates to an assembly for sealing a space between an edge of a door or window and an adjacent surface to avoid entrance of animals, such as rats, between the edge of the door or window and the surface.
BACKGROUND A general problem of entryway design for buildings relates to the dual issues of excluding inclement weather and animals or vermin from entering or impacting the interior when the entryway is shut. One category of known sealing strips for excluding inclement weather comprises flexible synthetic or rubber strips, which are installed at the perimeter of the door at an entryway. Another category of flexible strips for controlling internal temperature are manufactured with rows of tightly packed bristles.
However, vermin are wily and persistent in the face of currently-known flexible barriers, which are keeping them from shelter and/or food. The term vermin relates to animals considered to be pests, including rats and mice. Synthetic or rubber or bristle strips may present a challenge but not a lasting one, and especially rats or mice will find a way in to reach any available food.
An improvement to currently available seal strips is therefore needed.

DETAILED DESCRIPTION
Fig. 1 is a partially cut away perspective view of a reinforced flexible structure or seal 101 according to a first example embodiment, and Fig. 13 is a partially cut away perspective view of a reinforced flexible structure or seal 1301 according to a second example embodiment.
Each of the structures 101 and 1301 has a flexible outer material with a first side part 102a, 1302a and a second side part 102b, 1302b encompassing a plurality of metal wires 103, 1303, where each of the wires 103, 1303 run substantially in parallel to each other. The flexible structure or seal 101, 1301 may have a longitudinal extension, and the metal wires 103, 1303 may run substantially in the longitudinal direction of the structure or seal 101, 1301. The substantially parallel metal wires 103, 1303 are arranged at a distance to each other, and it is preferred that the metal wires 103, 1303 are arranged with a substantially equal spacing. It is preferred that the flexible outer material 102a, 102b, 1302a, 1303b encompasses the parallel metal wires 103, 1303 only. The flexible outer material 102a, 102b, 1302a, 1302b may have a flattened form with a substantially constant thickness. The flexible outer material 102a, 102b, 1302a, 1302b may be made of a flexible polymer or plastic material, such as flexible polyvinyl chloride, PVC, and/or a flexible rubber material, and may have a thickness in the range of 2 to 30 mm, such as in the range of 2 to 20 mm, such as in the range of 2 to 10 mm, such as in the range of 2 to 5 mm, such as in the range of 2,5 to 4 mm, such as about 3 mm.
In order to use the structures 101 or 1301 as a seal barrier for vermin, such as rats or mice, the wires shall be dimensioned and made of a material, which the rats and/or mice cannot bite them a way through. Thus, the wires shall have a thickness and be made of a material, which the rats and/or mice cannot bite through, and also the distance between the wires shall be so small, that the rats and/or mice cannot move in between the wires.
The wires 103, 1303 may be therefore be arranged at a distance to each other which is no larger than 20 mm, such as no larger than 19 mm, such as no larger than 18 mm, such as no larger than 17 mm, such as no larger than 15 mm, such as no larger than 12 mm, such as no larger than 10 mm, such as no larger than 9 mm, such as no larger than 8 mm, such as no larger than 7 mm, such as no larger than 6 mm, such as no larger than 5 mm, such as no larger than 4 mm, such as no larger than 3 mm, or such as no larger than 2 mm. Here, it is preferred that the distance between the wires 103, 1303 is no larger than 5 mm, such as no larger than 4 mm.
The wires may have a diameter of no less than 0,4 mm, such as no less than 0,6 mm, such as no less than 0,8 mm, such as no less than 0,9 mm, such as a diameter of 0,9 mm or 1 mm or 1,1 mm. The wires 103, 1303 may be made of steel or stainless steel with a diameter of no less than 0,4 mm, such as no less than 0,6 mm, such as no less than 0,8 mm, such as no less than 0,9 mm, such as a diameter of 0,9 mm or 1 mm, or the wires may be made of iron with a diameter of no less than 0,9 mm, such as a diameter of 1 mm or 1,1 mm. However, the wires may also be made as flexible metal wires, such as braided or twisted wires.
The flexible structure 101, 1301 may have different widths, but when used for sealing, the structure 101, 1303 may have a width in the range of 1,5 to 30 cm, such as in the range of 2 to 25 cm, such as in the range of 2 to 20 cm, such as in the range of 2 to 15 cm, such as in the range of 4 to 10 cm, such as in the range of 5 to 9 cm, such as about 8 cm.
By having the metal wires 103, 1303 running substantially in parallel, the structure 101, 1303 can bend or flex about an axis being substantially parallel to the metal wires 103, 1303, whereas bending or flexing of the structure 101, 1301 about an axis perpendicular to the parallel metal wires 103, 1303 will be rather limited due to the stiffness of the metal wires 103, 1303.
The main difference between the first structure or seal 101 and the second structure or seal 1301 is that for the first structure or seal 101, metal wires 103 are provided at a distance to each other in the whole width of the structure 101, while for the second structure or seal 1301, only a part of the structure or seal 1301 has metal wires 1303 running substantially parallel to each other.
Thus, the flexible structure or seal 1301 has a first section with a flexible outer material 1302a, 1302b encompassing a plurality of metal wires 1303 running substantially parallel to each other, where the first section has a maximum width defined by the maximum distance between the two outermost positioned metal wires 1303 of the plurality of substantially parallel metal wires. The flexible structure or seal 1301 further has a second section arranged next to the first section alongside one of the outermost positioned metal wires 1303. The second section may also be formed by a flexible material, which may be the same material as used for the first section, and the second section holds no metal wires running substantially parallel to the metal wires 1303 of the first section.
When using the flexible structure 1301 as a seal connected to the edge of a door or a window, there is no need to have metal wires running in the part of the structure, which may be the second section, and which is used for connecting the structure 1301 to the door or window edge. Thus, there is only a need to have metal wires running in the part of the structure or seal, which may be the first section, and which is positioned below or besides the door or window edge.
It is preferred that the second section of the structure or seal 1301 has a maximum width of no less that one quarter of the maximum width of the first section, such as no less than one third of the maximum width of the first section, such as no less than one half of the maximum width of the first section, such as no less than two thirds of the maximum width of the first section, such as no less than three quarters of the maximum width of the first section, such as no less than the whole width of the maximum width of the first section, such as no less than one and a half of the maximum width of the first section, or such a no less than twice the whole width of the maximum width of the first section.
It is within an embodiment of the disclosure that the distance from the lowermost arranged metal wire 103, 1303 to the lower edge of the structure 101, 1301 is smaller than the distance between neighbouring arranged metal wires 103, 1303. Thus, the distance from the lowermost arranged metal wire 103,1303 to the lower edge of the structure 101,1301 may be half or below half of the distance between neighbouring arranged metal wires 103, 1303. If the wires 103, 1303 for example are arranged at a distance to each other, which distance is at least 4 mm, such as 4 mm or 5 mm, the distance from the lowermost arranged metal wire 103,1303 to the lower edge of the structure 101, 1301 may be about 2 mm.
Figs. 14a, 14b, 14c and 14d shows partially cut away perspective views of reinforced flexible structures or seals 1401a, 1401b, 1401c and 1401d, according to example embodiments. The structure or seal 1401a of Fig. 14a is similar to the structure or seal 1301 of Fig. 13 in that the structure or seal 1401a has a first section with metal wires running substantially parallel to each other and a second section with no metal wires. The first section of the structure or seal 1401a is bent outwards or is at an angle relative to the second section, which holds no wires. Thus, when the structure 1401a is used as a door or port seal, the second section may be connected to the lower part or the edge of the door, while the first section extend below the door edge at an angle.
The structure or seal 1401b of Fig. 14b is similar to the structure or seal 1301 of Fig. 13 in that the structure or seal 1401b has a first section with metal wires running substantially parallel to each other and a second section with no metal wires. However, the first section is made up of a folded flexible material, providing an almost tubular shaped first section with a first and a second side. The folded flexible material may encompass metal wires in only one side or in both of the folded sides. The structure 1401b may for example be used as a seal for a garage port or door, such as a roller door.
The structure or seal 1401c of Fig. 14c is similar to the structure or seal 1301 of Fig. 13 in that the structure or seal 1401c has a first section with metal wires running substantially parallel to each other and a second section with no metal wires. For the structure 1401c, the width of the second section is smaller than the width of the first section. The first section of the structure or seal 1401c is formed with several curves to provide the first section with an improved flexibility when used for example as a door seal.
The structure or seal 1401 d of Fig. 14d is similar to the structure or seal 101 of Fig. 1 in that the structure or seal 1401 d has a metal wires running substantially parallel to each other in the whole width of the structure 1401 d. The structure or seal 1401d is also formed with several curves to provide an improved flexibility when used for example as a door seal.
Figs. 2a to 2d illustrate a reinforced flexible structure or seal 201 with disconnected reinforcement wires 203a, 203b according to an example embodiment, where Fig. 2a is a partial perspective view of the structure 201, and Figs. 2b to 2d are partial top down views. The structure 201 of Figs. 2a to 2d is equal to the structure 101 of Fig. 1 or the structure 1301 of Fig. 13, with the exception that the metal wires 103, 1303 are disconnected into two parts 203a and 203b. Thus, the structure 201 comprises a first part 204 with parallel metal wires 203a and a remaining second part with parallel metal wires 203b, and the metal wires 203a of the first part 204 may be disconnected from the metal wires 203b of the second part along a disconnection line substantially perpendicular to the longitudinal direction of the substantially parallel wires 203a, 203b. Disconnection of the wires 203a, 203b may be performed by cutting through one or both side parts of the flexible structure 201, whereby cut through holes 205 may appear in the flexible material encompassing the wires 203a, 203b, whereby a number of cut through holes 205 will appear along the disconnection line.
The structure 201 has the same flexibility around an axis being parallel to the metal wires 203a, 203a as the structure 101 of Fig. 1 and the structure 1301 of Fig. 13. However, due to the disconnection of the wires 203a, 203b, the first part 204 of the structure 201 can bend or flex relative to the remaining second part of the structure 201 about an axis perpendicular to the parallel metal wires 203a, 203b, which axis is defined by the disconnection line holding the through holes 205. This is illustrated in Figs. 2b to 2d, where Fig. 2c shows the first part 204 in a non-flexed position, Fig. 2b shows the first part 204 being flexed in a first direction, and Fig. 2c shows the first part 204 being flexed in a second direction opposite the first direction of Fig. 2b.
Fig. 16 illustrates a reinforced flexible structure or seal 1601 with disconnected reinforcement wires 1603a, 1603b according to an example embodiment. The structure 1601 of Fig. 16 is similar to the structure 201 of Fig. 2a, with the exception that the metal wires 1603a, 1603b are disconnected into the two parts 1603a and 1603b along a straight line, which is not perpendicular to the longitudinal direction of the substantially parallel wires 1603a, 1603b. Thus, the structure 1601 comprises a first part 1604 with parallel metal wires 1603a and a remaining second part with parallel metal wires 1603b, and the metal wires 1603a of the first part 1604 may be disconnected from the metal wires 1603b of the second part along a disconnection line, which is substantially straight and forms an acute angle a to the longitudinal direction of the substantially parallel wires 1603a, 1603b, where a may be in the range of 20° to 90°, such as in the range of 30° to 90°, such as in the range of 30° to 80°, such as in the range of 30° to 70°, such as in the range of 30° to 60° to the longitudinal direction of the substantially parallel wires 1603a, 1603b. Disconnection of the wires 1603a, 1603b may also here be performed by cutting through one or both side parts of the flexible structure 1601, whereby cut through holes 1605 may appear in the flexible material encompassing the wires 1603a, 1603b, whereby a number of cut through holes 205 will appear along the disconnection line.
In order to use the structures 201 or 1601 as a seal barrier for rats or mice, the distance between the ends of the disconnected wires shall be so small, that the rats and/or mice cannot move in between the disconnected wires. Thus, the distance between the closest wire ends of two closest neighbouring and disconnected or separated metal wires of the first part 203a, 1603a and the second part 203b, 1603b shall be no larger than 20 mm, such as no larger than 19 mm, such as no larger than 18 mm, such as no larger than 17 mm, such as no larger than 15 mm, such as no larger than 12 mm, such as no larger than 10 mm, such as no larger than 9 mm, such as no larger than 8 mm, such as no larger than 7 mm, such as no larger than 6 mm, such as no larger than 5 mm, such as no larger than 4 mm, such as no larger than 3 mm, or such as no larger than 2 mm. Here, it is preferred that the distance between ends of the wires 203a and 203b or 1603a and 1603b is no larger than 5 mm, such as no larger than 4 mm.
Fig. 17 illustrates bending of two reinforced flexible structures or seals, 1701a and 1701b, which are similar to the structure 1601 of Fig. 16 according to an example embodiment. Both structures 1701a, 1701b has a first part 1704a, 1704b with parallel metal wires being disconnected from the metal wires in a remaining second part along a disconnection line having an acute angle a to the longitudinal direction of the parallel wires. Each first part 1704a and 1704b is bended relative to the remaining second part along the corresponding disconnection line.
According to one or more embodiments of the disclosure, the flexible structure 101, 1301, 201,1601 can be used for door sealing in order to prevent animals or vermin from entering at the perimeter of the door when shut. This is illustrated in Fig. 3, which is an isometric illustration of a lower edge door sealing assembly 300 according to an example embodiment, and in Fig. 4, which is an enlarged isometric illustration of a part of the lower edge door sealing assembly 300 of Fig. 3.
The seal assembly 300 of Figs. 3 and 4 is arranged for sealing a space between a lower edge of a door 307 and an adjacent surface 310 to avoid entrance of animals between the lower edge of the door 307 and the surface 310. The seal assembly 300 comprises a flexible seal 301, which may be of the type 101 or 1301 as described in connection with Figs. 1 and 13, or which may be of the type 201 as described in connection with Figs. 2a to 2d. Thus, the seal assembly 300 comprises a reinforced flexible seal 301 having a width and a length and comprising a flexible outer material 302 encompassing a plurality of metal 303a, 303b wires running in parallel to each other in a longitudinal direction of the reinforced flexible seal 301. The wires 303a, 303b are arranged at a distance to each other, and the reinforced flexible seal 301 has a width for forming a seal between the edge of the door 307 and the surface 310. The metal wires 303a, 303b may extend substantially parallel to the longitudinal direction of the lower edge of the door 307. The seal assembly 300 has a connector or connecting plate 306, which may be made of steel or stainless steel, and which connects the reinforced flexible seal 301 to the edge of the door 307.
It is preferred that the reinforced flexible seal 301 has no other reinforcement means than the metal wires 303a, 303b, and therefore only comprises the metal wires 303a, 303b being surrounded by the flexible material 302. Also for the flexible seal 301 it is preferred that all the metal wires 303a, 303b are arranged substantially parallel to each other, and it is also preferred that successively arranged substantially parallel metal wires 303a, 303b are arranged with substantially equal spacing.
When the flexible seal 301 is of the type 101 or 1301 as described in connection with Figs. 1 and 13, at least part or all of the metal wires 303a, 303b extend in the whole length of the seal without any disconnection.
It is however preferred that the flexible seal 301 is of the type 201 as described in connection with Figs. 2a to 2d. Flere, the reinforced flexible seal 301 has a first flexible end part 304a with a first seal edge substantially perpendicular to the longitudinal direction of the reinforced flexible seal 301, and with the substantially parallel metal wires 303a of the first end part 304a being disconnected from the metal wires 303b running substantially in parallel within the reinforced flexible seal 301 next to the first end part 304a. The disconnection of the wires 303a and 303b may be made by cutting through one or both side parts 302 of the flexible structure 301, leaving cut through holes 305a in the encompassing flexible material 302. The holes 305a may be arranged along a disconnection line substantially perpendicular to the longitudinal direction of the parallel wires 303a, 303b and at distance from the first seal edge. For the embodiment illustrated in Fig. 3, the seal 301 also has a second flexible end part 304b in the opposite end of the first flexible end part 304a. The second flexible end part has a second seal edge substantially perpendicular to the longitudinal direction of the reinforced flexible seal 301, and with the substantially parallel metal wires of the second end part 304b being disconnected from the metal wires 303b running substantially in parallel within the reinforced flexible seal 301 next to the second end part 304b. Also for the second end part 304b, the disconnection of the wires 303a and 303b may be made by cutting through one or both side parts 302 of the flexible structure 301, leaving cut through holes 305b in the encompassing flexible material 302.
By having the flexible end parts 304a and 304b, the flexible seal 301 can be arranged with the end parts 304a, 304b extending on both sides of the door edge, to thereby obtain a close seal to the lower part of the frame of the door 307 to prevent animals or vermin from entering at the doorframe when the door 307 is shut.
The adjacent surface 310 may extend in a plane substantially parallel to the door edge, and the surface 310 can for example be a ground surface, a floor surface, a concrete surface, or a door threshold.
Also for the flexible seal 301 of the seal assembly 300, it is preferred that the the flexible outer material 302 has a flattened form with a substantially constant thickness, and that the outer material 302 is made of a flexible polymer or plastic material, such as flexible polyvinyl chloride, PVC, and/or of a flexible rubber material, and has a thickness in the range of 2 to 30 mm, such as in the range of 2 to 20 mm, such as in the range of 2 to 10 mm, such as in the range of 2 to 5 mm, such as in the range of 2,5 to 4 mm, such as about 3 mm. The wires 303a, 303b may be arranged at a distance to each other which is no larger than 20 mm, such as no larger than 19 mm, such as no larger than 18 mm, such as no larger than 17 mm, such as no larger than 15 mm, such as no larger than 12 mm, such as no larger than 10 mm, such as no larger than 9 mm, such as no larger than 8 mm, such as nor larger than 7mm, such as no larger than 6 mm, such as no larger than 5 mm, such as no larger than 4 mm, such as no larger than 3 mm, or such as no larger than 2 mm. It is preferred that the wires 303a, 303b are made of steel or stainless steel with a diameter of no less than 0,4 mm, such as no less than 0,6 mm, such as no less than 0,8 mm, such as no less than 0,9 mm, such as a diameter of 0,9 mm or 1 mm, but the wires 303a, 303b can also be made of iron with a diameter of no less than 0,9 mm, such as no less than 1 mm, such as a diameter of 1 mm, or such as a diameter of 1,1 mm. The flexible seal 301 may have a width in the range of 1,5 to 30 cm, such as in the range of 2 to 25 cm, such as in the range of 2 to 20 cm, such as in the range of 2 to 15 cm, such as in the range of 4 to 10 cm, such as in the range of 5 to 9 cm, such as about 8 cm. The distance between the first seal edge of the first end part 304a and the disconnection holes 305a, and thereby the width of the first end part 304a, may be in the range of 7 to 20 mm, such as in the range of 8 to 15 mm, such as about 10 mm. The width of the second end part 304b may be equal to the width of the first end part 304a.
According to one or more embodiments of the disclosure, the flexible structure 101, 1301, 201 can also be used for sealing a window 507 in order to prevent animals or vermin from entering through the perimeter of the window 507 when shut. This is illustrated in Fig. 5, which shows a lower edge window sealing assembly 500 according to an example embodiment. It is preferred that sealing assembly 500 has a flexible seal 501 of the type as described in connection with Figs. 2a and 2b, and that the seal 501 is similar to the seal 301 of Figs. 3 and 4. The seal 501 is connected to a lower frame edge of the window 507 by a connecting plate 506, which may be made of steel or stainless steel, and the seal 501 has a first flexible end part 504a and an opposite second flexible end part 504b, where the metal wires of the end parts 504a and 504b are disconnected from the metal wires in the remaining part of the seal 501 similar to the end parts 304a and 304b of the seal 310.
The sealing assembly 300 illustrated in Fig. 3 shows the sealing of a single door 307. It is also within embodiments of the disclosure to provide a sealing assembly of a door with two door wings. This is illustrated in Figs. 6a and 6b and Figs. 15a and 15b. Here, Figs. 6a and 6b illustrate a bottom sealed door assembly 600 having two oppositely arranged door wings or halves, a first door half 607a and a second 607b door half. Each door half 607a, 607b has a lower edge, wherein a first seal 601a is connected to the lower edge of the first door half 607a by a connecting plate 606a, and a second seal 601b is connected to the lower edge of the second door half 607b by a connecting plate 606b for sealing a space between the door edges and an adjacent surface 610 to avoid entrance of animals between the door edges and the surface. The first and second seals 601a and 601b may each be a flexible seal 601a, 601b, which may be of the type 101 as described in connection with Fig. 1, or of the type 201 as described in connection with Figs. 2a to 2d. It is preferred that each of the seals 601 a, 601 b are similar to the seal 301 of the assembly 300 of Fig. 3. Thus, each seal 601a and 601b may have a corresponding first flexible end part 604a and 604b, as shown in Fig. 6b, and an opposite second flexible end part (not shown in Fig. 6b), where the metal wires of the first end parts 604a and 604b are disconnected from the metal wires in the remaining part of the corresponding seal 601a and 601b by use of corresponding cut through holes 605a and 605b.
The sealed door assembly 600 is further provided with a vertical arranged flexible seal 601c connected to the second door half 607b by a connecting plate 606c for sealing any opening between the first and second door halves 607a and 607b when the door halves 607a and 607b are closed. It is also preferred that the seal 601c is of the type 201 as described in connection with Figs. 2a to 2d, and the seal 601c may have a first end part 604c with parallel metal wires being disconnected from the metal wires in the remaining part of the seal 601c by use of corresponding cut through holes 605c. The arrangement of the seal 601 c on the second door half 607b allows the first door half 607a to be opened inwards or the second door half 607b to be opened outwards.
Fig. 18 illustrates another sealed door assembly 1800 with two door wings according to an example embodiment. The door assembly 1800 is similar to the door assembly 600 of Fig, 6b with the exception that the door wings have flexible seals 1801a and 1801b of the type 1601 illustrated in Fig. 16, where the disconnection line of the metal wires forms an acute angle to the longitudinal direction of the metal wires. Thus, each door half has a lower edge, wherein a first seal 1801a is connected to the lower edge of the first door half by a connecting plate 1806a, and a second seal 1801b is connected to the lower edge of the second door half by a connecting plate 1806b for sealing a space between the door edges and an adjacent surface to avoid entrance of animals between the door edges and the surface. The first and second seals 1801a and 1801b are of the type 1601 as described in connection with Fig. 16, and each seal 1801a and 1801b has a corresponding first flexible end part 1804a and 1804b, where the metal wires of the first end parts 1804a and 1804b are disconnected from the metal wires in the remaining part of the corresponding seal 1801a and 1801b by use of corresponding cut through holes 1805a and 1805b. The sealed door assembly 1800 may also be provided with a vertical arranged flexible seal 1801c connected to the second door half by a connecting plate 1806c for sealing any opening between the first and second door halves, when the door halves are closed. It is also preferred that the seal 1801c is of the type 201 as described in connection with Figs. 2a to 2d, and the seal 1801c may have a first end part 1804c with parallel metal wires being disconnected from the metal wires in the remaining part of the seal 1801c by use of corresponding cut through holes 1805c. The arrangement of the seal 1801c on the second door half allows the first door half to be opened inwards or the second door half to be opened outwards.
Figs. 15a and 15b illustrate yet another bottom sealed door assembly 1500 with two oppositely arranged door wings or halves, a first door half 1507a and a second 1507b door half. Also her, each door half 1507a, 1507b has a lower edge, wherein a first seal 1501a is connected to the lower edge of the first door half 1507a by a connecting plate 1506a, and a second seal 1501b is connected to the lower edge of the second door half 1507b by a connecting plate 1506b for sealing a space between the door edges and an adjacent surface to avoid entrance of animals between the door edges and the surface. The first and second seals 1501a and 1501b may each be a flexible seal 1501a, 1501b, which may be of the type 101 or 1301 as described in connection with Figs. 1 and 13, or of the type 201 as described in connection with Figs. 2a to 2d. Here it is preferred that one or each of the seals 1501a, 1501b are similar to the seal 301 of the assembly 300 of Fig. 3. Thus, at alt least one seal 1501b may have a corresponding first flexible end part, where the end part 1504b of the seal 1501b is shown in Fig. 15b, and an opposite second flexible end part (not shown in Fig. 15b), where the metal wires of the first end part 1504b are disconnected from the metal wires in the remaining part of the seal 1501b by use of corresponding cut through holes 1505b.
The sealed door assembly 1500 is further provided with a vertical arranged connecting plate 1506c connected to the second door half 1507b for closing any opening between the first and second door halves 1507a and 1507b when the door halves 1507a and 1507b are closed. Thus, the connecting plate 1506c is arranged for allowing the second door half 1507b to be opened outwards.
The sealed door assembly 600 of Figs. 6a and 6b has the vertical flexible seal 601c arranged on the same side of the assembly 600 as the lower door seals 601a and 601b. It is also within embodiments that the vertical seal can be arranged opposite to the bottom seals. This is illustrated in Figs. 7a and 7b, which are cut through views of a sealed door assembly 700 with two door wings 707a and 707b, where Fig. 7a shows the assembly 700 with open door halves 707a and 707b, and Fig. 7b shows the assembly 700 with closed door halves 707a and 707b. The door assembly 700 has a first door half 707a with a first flexible seal 701a and a second door half 707b with a second flexible door seal 701b. The door seals 701a and 701b are similar to the door seals 601a and 601b of the assembly 600, and the seals 701a and 701b are also provided with corresponding first flexible end parts 704a and 704b. The assembly 700 is further provided with a vertical flexible seal 701 c, which is secured to the first door half 707a by a connecting plate, which is not shown. The first door half 707a is provided with a door handle 708 and a latch bolt 709 for keeping the first door half 707a in a closed position relative to the second door half 707b. The vertical seal 701c may be similar to the vertical seal 601c of the assembly 600, and may have a flexible end part, which is not shown. When the door halves 707a and 707b are in the closed position, the flexible end parts 704a and 707b may engage each other in an overlapping fashion, as shown in Fig. 7b, and thereby provide a closed sealing between the two bottom seals 701a and 701b.
Figs. 8a and 8b illustrate sealing of a lower edge of a port or door 807 according to an example embodiment. The space between the port or door 807 and an adjacent surface 810 is sealed to avoid entrance of animals between the lower edge of the port or door 807 and the surface 810. The sealing is provided by use of a flexible seal 801, which may be of the type 101 as described in connection with Fig. 1, or which may be of the type 201 as described in connection with Figs. 2a to 2d. Thus, the seal 801 comprises a flexible outer material 802 encompassing a plurality of metal wires 803 running substantially in parallel to each other in a substantially longitudinal direction of the reinforced flexible seal 801. The flexible seal 801 may be connected to the port or door 807 by a connecting plate 806 with the metal wires 803 extending substantially parallel to the longitudinal direction of the lower edge of the port or door 807.
However, the surface 810 may be uneven, which may rise a problem in obtaining a close sealing of the space between the edge of the port or door 807 and the surface 810, when the port or door 807 is in the closed position. This problem can be solved, as illustrated in Fig. 8b, by cutting an edge part of the reinforced flexible seal 801, which edge part faces the adjacent surface 810, where the cutting is performed to have the resulting cut edge part substantially following the adjacent surface 810 when the port of door 807 is in a closed position. The cutting may be performed by use of a pair of scissors or a wire cutter 811, which should be able to cut through both the flexible outer material 802 and the metal wires 803, depending on the irregularity of the surface 810.
Fig. 19 shows a cross-sectional view of a reinforced flexible structure or seal 1901 according to an example embodiment. The structure or seal 1901 may be used as a seal for a door assembly having first and second parts 1907a, 1907b, where the first part 1907a may be a movable part, to which the seal 1901 may be connected by a connecting plate 1906. The moveable door part 1907a may be a door or port of a container. The seal 1901 has a first section 1902a, a second section 1902b and a third section 1903c. The first section 1902a is made of a flexible material encompassing a plurality of reinforcing metal wires 1903. It is preferred that the second and third sections 1902b and 1902c are made of the same flexible material as the first section 1902a. The cross-sectional form of the first and second sections 1902a and 1902b may form a T-like shape, and also the cross-sectional form of the third and second sections 1902c and 1902b may form a T-like shape. The second section 1902b may extend in a direction substantially perpendicular or close to perpendicular to the direction of extension of the first section 1902a, and the third section 1902c is secured to the second section 1902b opposite and substantially parallel to the first section 1902a. Thus, the second section 1902b extends in a direction substantially perpendicular or close to perpendicular to the direction of extension of the third section 1902c. The second section 1902b forms a wall part, and when the seal 1901 is secured to a first door part 1907a, a first side wall of the second section 1902b faces an end wall of the first door part 1907a, and the second side wall of the second section 1902b may face an end wall of the second door part 1907b. The first and third sections 1902a and 1902c extend on both sides of the second section 1902b, but with a larger part of the first and third sections 1902a and 1902c extending to the side of the second side wall of second section 1902b. The first section 1902a has a larger part extending to the side of the second side wall of the second section 1902b than the third section 1902c, whereby the first section 1902a has an extension being large enough to provide a seal between the two door parts 1907a and 1907b when the moveable first door part 1907a is closed to the second door part 1907b.
Fig. 20 is a cross sectional view of a reinforced flexible structure or seal 2001 according to another example embodiment. The structure or seal 2001 may be also be a seal for a door assembly having first and second parts 2007a, 2007b, where the first part 2007a may be a movable part, to which the seal 2001 may be connected by a connecting plate 2006. The moveable door part 2007a may be a door or port of a container. The seal 2001 is similar to the seal 1901 of fig. 19 and has a first section 2002a and a second section 2002b, but the seal 2001 does not hold a third section as section 1902c of the seal 1901. Also for the seal 2001, the first section 2002a is made of a flexible material encompassing a plurality of reinforcing metal wires 2003. It is preferred that the second section 2002b is made of the same flexible material as the first section 2002a. The cross-sectional form of the first and second sections 2002a and 2002b may form a T-like shape, and the second section 2002b may extend in a direction substantially perpendicular or close to perpendicular to the direction of extension of the first section 2002a. The second section 2002b forms a wall part, and when the seal 2001 is secured to a first door part 2007a, a first side wall of the second section 2002b faces an end wall of the first door part 2007a, and the second side wall of the second section 2002b may face an end wall of the second door part 2007b. The first section 2002a extends on both sides of the second section 2002b, but the first section 2002a may have a larger part extending to the side of the second side wall of the second section 2002b, whereby the first section 2002a may have an extension being large enough to provide a seal between the two door parts 2007a and 2007b when the moveable first door part 2007a is closed to the second door part 2007b.
Fig. 21 is a cross sectional view of a reinforced flexible structure or seal 2101 according to yet another example embodiment. The structure or seal 2101 is rather similar to the seal 1901 of Fig. 19 and may be used as a seal for the door assembly of Figs. 19 replacing the seal 1901. The seal 2101 has a first section 2102a, a second section 2102b and a third section 2103c. The first section 2102a is made of a flexible material encompassing a plurality of reinforcing metal wires 2103. It is preferred that the second and third sections 2102b and 2102c are made of the same flexible material as the first section 2102a. The cross-sectional form of the first and second sections 1902a and 1902b may form an L or J-like shape, and also the cross-sectional form of the third and second sections 1902c and 1902b may form an L or J-like shape, where both the first and third sections 2102a and 2102c extend to the same side of the second section 2102b. The first section 2102a has a larger part extending to the side of the second section 2102b than the third section 2102c, whereby the first section 2102a has an extension being large enough to provide a seal between the two door parts 1907a and 1907b when replacing the seal 1901.
When compared to flexible structures or door seals without any reinforcing wires, the structure or seals 1901, 2001 and 2101 having first sections 1902a, 2002a, 2102a with reinforcing wires will be stronger in use and will not be so easily damaged for example by a truck hitting the seal 1901, 2001, 2101.
It is preferred that the reinforcing metal wires 1903, 2003, 2103 are provided in the first seal section 1902a, 2002a, 2102a only. The metal wires 1903, 2003, 2103 may be dimensioned similar to the proposed dimensions of the wires of the structures 101 and 1301, and the wires 1903, 2003, 2103 may also be arranged within in the first seal section 1902a, 2002a, 2102a similar to the proposed arrangements of the wires of the structures 101 and 1301.
The flexible structure or seal 1901,2001,2001 may have a longitudinal extension, and the metal wires 1903, 2003, 2103 may run substantially in the longitudinal direction of the structure or seal 1901, 2001, 2101. The substantially parallel metal wires 1903, 2003, 2103 may be arranged at a distance to each other, and it is preferred that the metal wires 1903, 2003, 2103 are arranged with a substantially equal spacing. The flexible outer material of the first sections 1902a, 2002a, 2102a may have a flattened form with a substantially constant thickness. The flexible outer material of the first sections 1902a, 2002a, 2102a may be made of a flexible polymer or plastic material, such as flexible polyvinyl chloride, PVC, and/or a flexible rubber material, and may have a thickness in the range of 2 to 30 mm, such as in the range of 2 to 20 mm, such as in the range of 2 to 10 mm, such as in the range of 2 to 5 mm, such as in the range of 2,5 to 4 mm, such as about 3 mm.
In order to use the structures or seal 1901, 2001, 2101 as a seal barrier for vermin, such as rats or mice, the wires 1903, 2003, 2103 shall be dimensioned and made of a material, which the rats and/or mice cannot bite them a way through. Thus, the wires shall have a thickness and be made of a material, which the rats and/or mice cannot bite through, and also the distance between the wires shall be so small, that the rats and/or mice cannot move in between the wires.
The wires 1903, 2003, 2103 may be therefore be arranged at a distance to each other which is no larger than 20 mm, such as no larger than 19 mm, such as no larger than 18 mm, such as no larger than 17 mm, such as no larger than 15 mm, such as no larger than 12 mm, such as no larger than 10 mm, such as no larger than 9 mm, such as no larger than 8 mm, such as no larger than 7 mm, such as no larger than 6 mm, such as no larger than 5 mm, such as no larger than 4 mm, such as no larger than 3 mm, or such as no larger than 2 mm. Here, it is preferred that the distance between the wires 1903, 2003, 2103 is no larger than 5 mm, such as no larger than 4 mm.
The wires 1903, 2003,2103 may have a diameter of no less than 0,4 mm, such as no less than 0,6 mm, such as no less than 0,8 mm, such as no less than 0,9 mm, such as a diameter of 0,9 mm or 1 mm or 1,1 mm. The wires 1903, 2003, 2103 may be made of steel or stainless steel with a diameter of no less than 0,4 mm, such as no less than 0,6 mm, such as no less than 0,8 mm, such as no less than 0,9 mm, such as a diameter of 0,9 mm or 1 mm, or the wires may be made of iron with a diameter of no less than 0,9 mm, such as a diameter of 1 mm or 1,1 mm. The first sections 1902a, 2002a, 2102a may have different widths, but when used for sealing, the first sections 1902a, 2002a, 2102a may have a width in the range of 1,5 to 30 cm, such as in the range of 2 to 25 cm, such as in the range of 2 to 20 cm, such as in the range of 2 to 15 cm, such as in the range of 4 to 10 cm, such as in the range of 5 to 9 cm, such as about 8 cm.
By having the metal wires 1903, 2003, 2103 running substantially in parallel, the first sections 1902a, 2002a, 2102a can bend or flex about an axis being substantially parallel to the metal wires 1903, 2003, 2103, whereas bending or flexing of the first section 1902a, 2002a, 2102a about an axis perpendicular to the parallel metal wires 1903, 2003, 2103 may be rather limited due to the stiffness of the metal wires 1903, 2003, 2103 when using steel or stainless steel wires. However, it is within a preferred embodiment that the wires 1903, 2003, 2103 are flexible metal wires, such as braided or twisted wires, which can be bend in all directions, whereby the first sections 1902a, 2002a, 2102a can bend in all or several directions.
The present disclosure also covers a system and a method for coating a plurality of metal wires with polymer to produce a reinforced flexible structure of metal wires encompassed by polymer. Such a reinforced flexible structure may be used as a reinforced flexible seal in a sealing assembly according to embodiments of the present disclosure.
