A SEAL COMBINATION WITH A LOWER SEAL PART HOLDING A BRUSH OR FIBRE MATERIAL RELEASABLY SECURED TO AN UPPER SEAL PART AND A SEAL WITH A LOWER FLEXIBLE SEAL PART A SEAL ASSEMBLY USING THE SEAL COMBINATION

TECHNICAL FIELD

The disclosure relates to a seal combination or seal for sealing a space, such as a space between an edge of a wall, fence, a door or sliding door, door leaf or door wing, port or window and an adjacent surface to avoid entrance of for example unwanted animals, insects, or water between the edge of the wall, fence, door or window and the surface. The unwanted animals or water may include rats, mice, rainwater, sewage water, and water from flooding. The structure or seal may also help in preventing temperature changes across the sealed space.

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.

Thus, there is a need for an improved seal being both reinforced and flexible and which is able to maintain the reinforcement and flexibility during use. Strip brushes are commonly used as weather or pest seals for turning or sliding doors, where the brushes are secured to the bottom part of a metal rail, and where the upper part of the metal rail is secured at the bottom of the door. However, when using a non-flexible metal rail for securing the sealing brushes to the door, there is a problem in that the end parts of a metal rail may be deformed during use, leaving a space open at the end of the rail. The commonly used strip brushes, which are installed at the perimeter of the door or sliding door at an entryway, have an advantage in that the bristles or brushes are very flexible and can follow irregularities, such as irregularities on a ground surface adjacent to door or sliding door. However, the bristles or brushes get worn out during use, requiring that the bristles or brushes has to be replaced at regular intervals, which is both costly and time consuming.

Thus, there is a need for an improved seal having the advantages of the known sealing strips holding packed bristles or fibre brushes, but which allows a quick and easy replacement of worn out bristles or brushes.

DETAILED DESCRIPTION

Fig. 1 is a partially cut away perspective view of a reinforced flexible structure or seal 101 without deformations according to a first example embodiment, and Fig. 2 is a partially cut away perspective view of a flexible structure or seal 201 without deformations according to a second example embodiment.

Each of the structures or seals 101 and 201 has a flexible outer material with a first side part 102a, 202a and a second side part 102b, 202b, encompassing or enclosing a plurality of elongated metal members or metal wires 103, 203, where each of the wires 103, 203 run substantially in parallel to each other. The wires 103 and 203 run substantially in parallel to each other. The flexible structure or seal 101 and 201 may have a substantial longitudinal extension, and the elongated metal members or metal wires 103, 203 may run substantially in the longitudinal direction of the structure or seal 101 , 201. The substantially parallel elongated metal members or metal wires 103, 203 are arranged at a distance to each other, and it is preferred that the elongated metal members or metal wires 103, 203 are arranged with a substantially equal spacing. It is preferred that the flexible outer material 102a, 102b, 202a, 202b encompasses or encloses the parallel elongated metal members or metal wires 103, 203 only.

The flexible outer material 102a, 102b, 202a, 202b, may have a flattened form with a substantially constant thickness. The flexible outer material 102a, 102b, 202a, 202b 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 seals 101 , 201 the wires may be dimensioned and made of a material, which 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, 203 may 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, 203 is equal to or no larger than 8 mm, equal to or no larger than 7 mm, equal to or no larger than 6 mm, equal to or no larger than 5 mm, or equal to or no larger than 4 mm.

The wires 103, 203 may be made of steel or stainless steel or spring steel, or the wires may be made of iron. The wires 103, 203 may also be made as flexible metal wires, such as braided or twisted wires. The metal wires 103, 203 can also be formed as narrow metal strips having a width, which may be substantially equal to the thickness of the narrow metal strips, or in the range of one to two or three times the thickness of the narrow metal strips. The wires or thin metal strips 103, 203 may have a thickness or diameter equal to or no less than 0,4 mm, equal to or no less than 0,6 mm, equal to or no less than 0,7 mm, equal to or no less than 0,8 mm, equal to or no less than 0,9 mm, equal to or no less than 1 mm, equal to or no less than 1 , 1 mm, equal to or no less than 1 ,2 mm, equal to or no less than 1 ,2 mm, equal to or no less than 1 ,3 mm, equal to or no less than 1 ,4 mm, equal to or no less than 1 ,5 mm, equal to or no less than 1 ,6 mm, equal to or no less than 1 ,7 mm, equal to or no less than 1,8 mm, equal to or no less than 1,9 mm, equal to or no less than 2,0 mm, equal to or no less than 2,1 mm, equal to or no less than 2,2 mm, equal to or no less than 2,4 mm, equal to or no less than 2,7 mm, or equal to or no less than 3 mm.

When the wires 103, 203 are formed as metal strips, the metal strips may have a width equal to or no less than 1 mm, equal to or no less than 1,5 mm, equal to or no less than 2 mm, or equal to or no less than 2,5 mm.

The flexible structure 101 , 201 may have different widths, but when used for sealing, the structure 101 , 201 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 or 7,5 cm.

By having the metal wires 103, 203 running substantially in parallel, the structure 101, 201 can bend or flex about an axis being substantially parallel to the metal wires 103, 203, whereas bending or flexing of the structure 101 , 201 about an axis perpendicular to the parallel metal wires 103, 203 will be rather limited due to the stiffness of the metal wires 103, 203.

The structure or seal 201 of Fig. 2 is substantially equal to the structure or seal 101 of Fig. 1 , but some metal wires 203 may be omitted in the upper part of the structure 201.

One of the problems with the structures 101 and 201 is that when the structure 101, 201 , is used for example as a seal or barrier at the bottom of a door or at and edge of a door leaf, the opening and closing of the door may bend the lower part of the structure 101, 201 back and forth along an axis substantial parallel to the metal wires 103, 203, which bending may cause the metal wires 103, 203 to move relative to the flexible outer material 102, 202. The result may be that for an end part of the structure 101, 201 , part of the metal wires 103, 203 may extend outside the end part of the flexible outer material 102, 202. A solution to this problem may be to provide deformations along the metal wires 103, 203 being embedded or enclosed in the flexible outer material 102, 202. This is further illustrated in Figs. 3 and 4.

Fig. 3 is a perspective view of a reinforced flexible structure or seal 301 without deformations. The seal 301 may be equal to any of the above discussed seals 101 and 201 , and thus has a flexible outer material 302 encompassing or enclosing a plurality of elongated metal members or metal wires 303, where the wires 303 run substantially in parallel to each other. There may be metal wires 303 in the whole width of the seal 301 , as for the seal 101 , or there may be metal wires 303 in only a part of the width of the seal as for the seal 201.

The seals 101, 201 and 301 may be produced by an extrusion process.

Fig. 4 is a perspective view of a reinforced flexible structure or seal 401 similar to the seal 301 , but where the seal 401 is provided with bent, bulging or wavelike deformations 404. The seal has a flexible outer material 402 encompassing or enclosing a plurality of elongated metal members or metal wires 403, where the wires 403 run substantially in parallel to each other.

For the seal 401, the embedded elongated metal wires 403 hold several bent, bulging or wavelike deformations 404 in the longitudinal direction of the wires 403. Due to the deformations 404 of the metal wires 403, the flexible outer material 402 enclosing the metal wires 403 and thereby the outer surfaces of the reinforced flexible seal 401 are deformed accordingly. The metal wires 403 holding the wavelike deformations 404 in the longitudinal direction, run substantially parallel to each other. Thus, the bent, bulging or wavelike deformations 404 extend substantially perpendicular to a plane defined by the lengthwise and widthwise directions of the reinforced flexible seal 401 as illustrated in Fig. 4. By having the metal wires 403 deformed by several bent, bulging or wavelike deformations 404 while being embedded within the flexible outer material 402, the metal wires 403 will be locked within the flexible material 402, and the elongated metal wires 403b may not be able to move relative to the flexible material 402, if the flexible seal 401 is flexed back and forth relative to a lengthwise direction of the elongated metal wires 403 and the flexible seal 401. When the metal wires 403 are held in position within the seal 401, the reinforcement of the seal 401 is maintained during use.

The bent, bulging or wavelike deformations 404 may be bends or stable bends, which may include bent deformations, curve-shaped bends, and/or wave-shaped bends.

For the seal 401 of Fig. 4, all the deformations, bends, or wavelike deformations 404 are provided for all the wires 403 extending within the seal 401. However, if a part of the seal 401 is used for connection to a door leaf of door wing, any wires 403 extending within such a connection part may not be deformed, since such a connection part will not be flexed during opening and closing of the door leaf or door wing holding the seal 401.

For the seal 401 , the flexible outer material 402 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. The thickness may be substantially constant.

For the seals 401 , the flexible outer material 402 may be made of a plastic material or flexible polymer material. The flexible outer material 402 may be a material comprising a natural polymer material such as rubber and/or a synthetic polymer material such as synthetic rubber. The flexible outer material 402a, 402b may be a material comprising a thermoplastic elastomer, TPE, material, a thermoplastic vulcanizates, TPV, type material or a polyvinyl chloride, PVC, material. The flexible outer material 402 may have a shore hardness, Shore A, of not below 40, such as not below 50, such as not below 60, such as not below 65, such as not below 70, such as not below 75, such as in the range of 75-80. For some purposes, even harder material may be used having a shore hardness, Shore A, of not below 80, such as not below 85, such as not below 90. The flexible outer material 402a, 402b may be a polymer material is selected from the range of Santoprene™ materials, such as Santoprene™ 201-73.

Also, for the seals 401 , the wires 403 should preferably 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. It is within a preferred embodiment that for at least part of or all of said plurality of elongated metal wires 403, the distance between two neighbouring wires does not exceed a predetermined maximum distance. The reinforced flexible seal 401 has a lower or outer edge, and it is preferred that the spacing between said lower or outer edge and a lower- or outermost positioned elongated metal wire is smaller than said predetermined maximum distance. It is within a preferred embodiment that the bulging or wavelike deformations in the longitudinal direction of a wire are arranged with substantially equal spacing. The reinforced flexible seal 401 has a lower or outer edge, and the spacing between said lower or outer edge and a lower- or outermost positioned elongated metal wire should preferably be smaller than said substantially equal spacing.

The wires 403 may be arranged at a distance to each other which is 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 403a or 403b is equal to or no larger than 8 mm, equal to or no larger than 7 mm, equal to or no larger than 6 mm, equal to or no larger than 5 mm, or equal to or no larger than 4 mm.

The wires 403 may be made of steel or stainless steel or spring steel, or the wires may be made of iron. The wires 403 may also be made as flexible metal wires, such as braided or twisted wires. The metal wires 403 can also be formed as narrow metal strips having a width, which may be substantially equal to the thickness of the narrow metal strips, or in the range of one to two or three times the thickness of the narrow metal strips. The wires or thin metal strips 403 may have a thickness or diameter equal to or no less than 0,4 mm, equal to or no less than 0,6 mm, equal to or no less than 0,7 mm, equal to or no less than 0,8 mm, equal to or no less than 0,9 mm, equal to or no less than 1 mm, equal to or no less than 1 , 1 mm, equal to or no less than 1 ,2 mm, equal to or no less than 1 ,2 mm, equal to or no less than 1,3 mm, equal to or no less than 1,4 mm, equal to or no less than 1,5 mm, equal to or no less than 1 ,6 mm, equal to or no less than 1 ,7 mm, equal to or no less than 1,8 mm, equal to or no less than 1 ,9 mm, equal to or no less than 2,0 mm, equal to or no less than 2,1 mm, equal to or no less than 2,2 mm, equal to or no less than 2,4 mm, equal to or no less than 2,7 mm, or equal to or no less than 3 mm. When the wires 403 are formed as metal strips, the metal strips may have a width equal to or no less than 1 mm, equal to or no less than 1 ,5 mm, equal to or no less than 2 mm, or equal to or no less than 2,5 mm.

The flexible structure 403 may have different widths, but when used for sealing, the structure 403 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 or 7,5 cm.

The seal 401 of Fig. 4 may be obtained by first producing the seal 301 of Fig. 3, which can be produced by an extrusion process, and then expose the seal 301 to a further process for forming the wavelike deformations 404.

Fig. 5 shows a seal combination 500 with a lower seal part holding a brush or fibre material 502 according to a first example embodiment. The seal combination 500 comprising an upper seal part 501 , which may be formed at least partly by a flexible seal made of a flexible material, and a lower seal part holding a brush or fibre material 502.

The assembly 1500 comprises a door or door wing 1501 attached to a door frame 1506 with a hinge 1507, where the door or door wing 1501 has an outer edge part 1503, with a gap 1502 provided between the outer edge part 1501 and a floor or ground surface 1504. The seal combination 1400 is secured to the outer edge part 1503 of the door or door wing 1501 with the bottom part of the upper seal part 1401a and the lower seal part 1401b extending below the outer edge part 1503 of the door or door wing 1501 , to thereby seal the gap 1502 between the outer edge part 1503 and the floor or ground surface 1504.

Figs. 16a and 16b illustrate a commercially available flexible fabric or web like sheet or band 1600 having hook fasteners 1601 at a front side and a self-adhesive back side. In Fig. 16a the back side is covered by a protective sheet layer 1602, which can be a paper or plastic sheet, and in Fig. 16b the protective sheet layer 1602 is removed to uncover the self-adhesive back side. The hook sheet or band 1600 may be made of a plastic material such as nylon.

This type of band or sheet 1600 may be used as the strip of hook fasteners 506 secured to the lower seal part holding the brush or fibre material 502 as illustrated in Figs. 8a and 8b. The type of band or sheet 1600 may also be used at the sheets 605 and 1305 of the door sealing assemblies of Figs. 6 and 13.

A flexible fabric or web like sheet or band similar to the band 1600 but provided with loop fasteners instead of hook fasteners 1601 at a front side is also commercially available and may be made of a plastic material such as nylon. This type of loop band may be used as the flexible fabric or web like sheets 503, 703, 903a, 903b, 1103 and 1203 of Figs. 5, 7b, 9a, 9b, 11 and 12.
