Description

TITLE

DEVICE AND METHOD FOR GLAZING OF DOOR

TECHNICAL FIELD The invention relates to a door, comprising a unit of glass inserted in an existing opening of a door and fastened to the door via an outer strip placed on one side of the unit of glass and an inner strip placed on the other side of the unit of glass. The invention also relates to a glazing method for a door.

BACKGROUND ART

Doors are composited by a number of layers that from the outside of a building generally and structurally comprises; a surface layer that constitutes an outer side intended to face away from the building; a stabilizing layer against the surface layer; an insulation layer against the stabilizing layer; a stabilizing layer against the insulation layer; and a surface layer that constitutes an inner side of the door intended to face towards the inside of the building.

Glazing of doors means that a unit of glass is mounted in a through-and- through opening made in the door. The opening can be made in connection with the manufacturing of the door whereupon a piece of the insulation is replaced by a surrounding wood strip that delimits the opening. During glazing the unit of glass is mounted into the opening that is delimited by the wood strip and thereafter is held in place between an outer strip and an inner strip. The outer strip is attached to the wood strip from the outside and the inner strip is attached to the wood strip from the inside.

A problem with the method of manufacturing and the device described is that the surrounding wood strip and the insulation must be adapted, which gives rise to complicated production methods.

-:r.o *;; Π < UΓ\ TR \N^l- Λ ' I H In the cases where a door without glass is to be remade into a glazed door, a through-and-through opening is made in the door. The unit of glass is thereafter put into place and the outer strip is applied on the outside of the door and the inner strip is applied on the inside of the door. The inner strip is thereafter attached to the outer strip by means of through-and-through self tightening screws, i.e. screws that thread and automatically tightens in the surrounding material. Such an arrangement puts demands on all of the materials being part of the arrangement. For instance, it can be mentioned that the outer strip must be of a material soft enough to allow the self tightening screws to thread and obtain a pulling force. Examples of materials of this kind are the common kinds of wood being used for production of furniture and construction of houses.

A problem with the mentioned method and device is that the outer strip is too soft to resist wind and weather for a long period of time.

Even if the methods and the devices according to prior art functions satisfactorily in themselves, a desire for a cheaper, more simplified and improved manufacturing together with an increased life of glazed doors exists.

SUMMARY OF THE INVENTION

The present invention intends to solve the above stated problems through a simplified and improved manufacturing together with an increased life of glazed doors.

The problems are solved with a door, comprising a unit of glass inserted into a opening made in the door and fastened to the door via an outer strip placed on one side of the unit of glass and an inner strip placed on the other side of the unit of glass, where the inner strip and the outer strip forms a joining bond together with a joining device. The invention is characterized by that the joining device comprises a male element comprising a male part and that the joining device comprises a female part comprising a through-and through opening with clamping devices arranged in connection to the opening. The male part and the female part are arranged to engage with each other through that the male part is inserted into and through the opening in such a way that the male part at least partly is surrounded by the clamping device, whereupon the joining bond is formed by that the clamping device engages with the male part when forces have arisen between the outer strip and the inner strip that tries to pull the joining bond apart.

With "engage with" is here meant that the clamping device locks the female part in position relative to the male part. The locking takes place through that the clamping device is in contact with the male part in such a way that it admits movement of the male part in the opening in one direction, but prevents movement of the male part in the opposite direction. The clamping device can during locking be arranged at an angle relative to the male part and arranged to use the friction between the clamping device and the male part in such a way that all of the force that during the movement of the male part would be directed in the direction of movement of the male part instead is absorbed by the clamping device and prevents movement. The material in the clamping device can be allowed to be deformed somewhat under the precondition that the male part does not move further than what can be considered suitable in order for the joining band to a desired degree seal between the strips and the door, and the unit of glass respectively. The most optimal is however that the clamping device is as inelastic as possible so that the movement of the male part is minimized.

An advantage with the invention is that the joining device gives rise to a simple manufacturing method and a very sturdy joining bond. It has been shown that the joining device produces a strong joining bond that is inflexible. The joining device according to the invention additionally enables a great number of possibilities concerning choice of materials, tolerances and methods. The clamping device may for instance comprise lips with a first end and a second end and that during engagement with the male part at least partly extends along the length extension of the male part/male element and that at least in its first end is attached to the female part and whose second end is arranged to engage with the male part as the joining device is affected by forces trying to pull the joining bond apart.

Both the outer strip and the inner strip may comprise holes in which, or in connection to which, the female part or the male part is arranged. The female part or the male part can be fastened in the holes by threads, force fitting or any other suitable way. Both of the strips can comprise slits that connect the outside of the strip with the hole in such a way that the female part can be mounted in the hole by being inserted into the slit in a direction essentially perpendicular to the axial extension of the hole, i.e. in a direction in a radial direction when the hole is cylindrical.

The joining device can comprise an adapter that can be fastened in the hole by screwing, force fitting or any other suitable way. The adapter comprises a hole that is adapted to the female part and the male part in such a way that the male part can be inserted into the female part as the outer strip as the outer strip is to be attached to the inner strip. The adapter is thus arranged to house the female part and/or the male part.

As the female part is arranged inside the adapter, the hole of the adapter is adjusted to fit the opening in the female part. The hole of the adapter is preferably coaxially arranged with the opening in the female part.

The joining device may however comprise a distancing element comprising a hole comprising the female part. The distancing element may be attached directly to the hole in the outer strip or the inner strip via threads or force fitting or similar, but can also be attached to the adapter via threads or force fitting or any other suitable way.

As the male part is fitted into the adapter, the hole of the adapter is adjusted to fit the male part in such a way that the male part is attached to the adapter without being the weak link in the joining bond. The adapter can thus comprise threads for fastening of the male part via corresponding threads of one end of the male part. The second end of the male part is then intended to join bond with the female part.

The adapter may also comprise threads in the hole adapted to corresponding outer threads of the female part for fitting of the female part into the adapter. The female part may otherwise be fitted into the adapter by force fitting or similar. The adapter may also be divided into a number of parts between which the female part is arranged and is clamped into place as the parts are assembled to form the adapter. The adapter is then fastened in the hole in the outer strip or the inner strip, or in both if two adapters are used.

The above is valid also when more than one female part is used in the hole in any of the strips, the adapter or the distancing element.

When the female part is arranged inside the hole in any or both strips they can be secured by means of plugs comprising channels. The channels are preferably coaxially aligned with the opening in the female part or larger than the opening in order to admit that the male part can pass through the opening in the female part. The plugs can be fastened in the hole by means of force fitting, threads or a similar known method to fasten plugs into holes. When a female part is used a plug on each side of the female part is needed. The plug facing the bottom of the hole constitutes a distancing device between the bottom of the hole and the female part so that the male part can pass the female part without touching the bottom of the hole. The plug facing out from the opening of the hole, i.e. in the same direction as the direction the male part is inserted into the hole in, keeps the female part in place so that the female part can constitute a part of the joining device without being pulled out when forces exist that tries to pull the joining bond apart. When more than one female part is used in the hole of any one or both of the strips, the female parts can be separated with the aid of more than two plugs comprising through-and-through channels. As an example it can be mentioned that two female parts are used in the hole. With reference to what has been mentioned above concerning a female part, the second plug constitutes a distancing element between the inner female part and the outer female part and a third plug is placed on the other side of the of the outer female part in order to keep the female part in place so that the joining bond does not release. An advantage with having two female parts is that the male part can not be tilted at an angle in the hole since the two clamping devices is located at a distance from each other and removes the degree of freedom for the male part to rotate in a radial direction around an opening in a female part.

The male element comprises a first end section and a second end section, whose first and/or second end section may be chamfered for guidance of the male element into the hole.

The outer strip comprises holes that each one may be equipped with a funnel-shaped orifice intended to guide the male element towards the opening. The holes are not through-and-through but are made on the inner side of the outer strip and a suitable distance into the outer strip in the direction towards the outer side of the outer strip. The holes can be made by drilling or any other suitable technique.

An advantage with funnel-shaped orifices is that the funnel-shaped orifice admits that the outer strip and the inner strip forms a joining bond despite that the centre line of the male element does not have to coincide with the centre line of the corresponding hole in the outer strip as the male element is directed towards the hole. The funnel-shaped orifice guides the male element properly; in such a way that the male element is inserted into the hole whereupon the joining bond is formed.

The male element may have a dimension admitting an allowance fitting between the male element and the opening in the female part in the absence of the clamping device. The part of the female part that lacks the clamping device is denominated female body and may have any possible shape depending on which of the alternatives mentioned above that is used to secure the female part into position in the hole. The female body may comprise flanges intended to fasten the female part in the surrounding material and thereby secure the female part in position in the hole. The male part preferably is a plug in a suitable material. Neither funnel-shaped orifices nor pointed end sections are then necessary for guidance as the allowance fit gives rise to guidance. The clamping device however makes sure that the joining bond is secured during mounting despite the allowance fitting between the opening of the female part and the male part.

The inner strip may as previously mentioned comprise holes (hereafter also called inner holes) or channels placed essentially opposite to the holes in the outer strip, whereupon each inner hole or channel is arranged to receive the male element in such a way that the male element is brought in a direction towards the funnel-shaped orifice as the inner strip and the outer strip are moved towards each other. The inner holes are blind, i.e. not through-and- through, but are made on the inner side of the inner strip and a suitable distance into the inner strip in a direction towards the outer side of the inner strip. The inner side of the inner strip faces the door. The holes can be made using drilling or any other suitable technique. The channels however are through-and-through the inner strip and can be made using drilling or any other suitable technique. The invention also relates to a method for glazing of a door, where an opening is made in the door where after a unit of glass is placed in the opening. The opening can be made already during the manufacturing of the door or after that the door is manufactured. The unit of glass is fastened into the door via an outer strip placed on one side of the unit of glass and an inner strip placed on the other side of the unit of glass. The invention is characterized by that the inner strip and the outer strip is joined by means of a joining device, comprising a female part and a male part according to the above, in such a way that the outer strip and the inner strip forms a joining bond together with the joining device.

An advantage with the method is that the female part and the male part provides for the above mentioned possibilities for guidance which provides that the outer strip may consist of a rough and weather resistant material without the requirement of high tolerances during manufacturing.

To obtain a joining bond the strips are forced towards each other with the aid of a suitable pressing device, for instance screw clamps or hydraulic or pneumatic clamps

The male part preferably consists of an essentially cylindrical body being adapted for engaging with the opening in the female part adapted to engage with the clamping device. In the cases where the opening does not have a circular cross section the plugs are designed in the corresponding way, for instance with an oval cross section, or square, rectangular, wedge shaped, round, triangular, polygonal etc.

According to one embodiment of the invention the outer strip has a density that is at least twice as high as the inner strip. An advantage with this embodiment is that the high density gives a durable and weather resistant door with an increased life. It is previously known to use soft materials in the outer strip, but such materials have a tendency to start to rot and crack, whereupon water may penetrate through the outer strip or between the strip and the unit of glass.

According to an embodiment of the invention, the inner strip has a maximum density of 500 kg/m³. The inner strip does not have to be limited to be softer than the outer strip, but according to another embodiment the density of the inner strip can amount to the same density as the outer strip.

According to one embodiment of the invention the outer strip has a density that exceeds 750 kg/m³. Examples of such materials are plastic and composite materials. Examples of composite materials are wood laminated

(glued together) with glue, a so called HDF (High Density Fibre Board), that means a fibre board of high density. Composite materials may also be plastic layers laminated with glue. Other materials that may come into question are woods with a high density, for instance ebony.

The door preferably comprises a laminated structure comprising:

- an outer surface layer;

- an outer stabilizing layer against the outer surface layer; - an insulation layer against the outer stabilizing layer;

- an inner stabilizing layer against the insulation layer, and;

- an inner surface layer.

The outer surface layer may be made out of wood or any other suitable material. The material is preferably water-repellent or impregnated with a water-repellent material.

The outer stabilizing layer preferably comprises a material with an expansion coefficient that compensates the changes in the outer layer depending on for instance temperature and humidity. Examples of such materials are aluminium and sheet metal. The stabilizing layer may also consist of a material that is unaffected by temperature and humidity changes. Such a layer counteracts that the outer surface layer changes during said changes in the surrounding. Examples of such materials are hard plastic laminates as for instance kevlar or glass fibre.

The insulating layer preferably consists of a fibre material containing a sufficient amount of air to obtain a suitable insulating property. Examples of such fibres are cellulose fibres or oil based fibres such as plastic fibres.

The inner stabilizing layer preferably comprises a material with an expansion coefficient that compensates the changes in the outer layer depending on for instance temperature and humidity. Examples of such materials are aluminium and sheet metal. The stabilizing layer may also consist of a material that is unaffected by changes in temperature and humidity. Such a layer counteracts that the inner surface layer changes during said changes in the surrounding. Examples of such materials are hard plastic laminates as for instance kevlar or glass fibre.

The inner surface layer can be made of wood or any other suitable material. The inner surface layer normally consists of an aesthetically attractive material, but may be treated to, for instance, resist fire.

It shall however be mentioned that the door and glazing method according to the invention are not limited to doors of a special structure or a special material. On the contrary, one of the advantages with the invention is that the method can be used on any imaginable door structure with any constituting materials.

The unit of glass preferably consists of an outer pane of glass and an inner pane of glass. The outer pane of glass is intended to face away from a building and the inner pane of glass is intended to face into a building. The unit of glass comprises a frame part placed between the outer pane of glass and the inner pane of glass. The frame part extends along the periphery of the panes of glass and is sealed against the panes of glass with a suitable sealing agent. The unit of glass can of course consist of a single pane of glass or more panes than two.

The funnel-shaped orifice of the outer strip preferably has an angle of 20°- 70° between two opposing tangents of the sides of the orifice. The invention is not limited to the mentioned interval, but a funnel-shaped orifice with an angle being greater than or smaller than the mentioned interval is possible if the funnel-shaped orifice still provides for the wanted guidance of the male element to the hole in the outer strip.

The joining device can consist of any known materials capable of holding the outer strip and the inner strip together. The joining device can also combine the force fitting of the male element in the hole and the above described locking of the male part in the female part.

Fig. 1 schematically shows a perspective view of a door 1 with a unit of glass 2 fastened to the door according to previously known technique. The unit of glass 2 is designed with a rectangular geometry and is placed relatively central in the door. The unit of glass 2 may be placed anywhere in the door 1. The unit of glass 2 does not need to be designed with a rectangular geometry, but can be designed with any preferred geometry, for instance oval, circular, rhombic, parallel trapeze etc. The unit of glass 2 is placed directly into an existing opening 3 of the door 1. The opening 3 can either be made directly during the manufacturing of the door 1 , or the opening can be made in the door 1 after manufacturing.

The unit of glass 2 is fastened to the door 1 with the aid of an outer strip 4 and an inner strip 5. Both the outer strip 4 and the inner strip 5 extends along the whole of the periphery of the unit of glass 2 and thus also along the periphery of the opening 3. A number of screws 6 are screwed from the inner strip 5 and towards the outer strip 4. The screws 6 are screwed in the direction from the inner strip 5 towards the outer strip 4.

Fig. 2 schematically shows a cross section along the line B-B in the segment A, of a lower part of the unit of glass 2 fastened in the door 1 , according to previously known technique. Fig. 2 shows that the door 1 consists of a laminated structure comprising:

- an outer surface layer 7; - an outer stabilizing layer 8 against the outer surface layer 7;

- an insulation layer 9 against the outer stabilizing layer 8;

- an inner stabilizing layer 10 against the insulation layer 9, and;

- an inner surface layer 11.

The outer surface layer 7 is intended to face away from a building and the inner surface layer 11 is intended to face toward the inside of a building. The outer strip 4 is placed against the outer surface layer 7 and the unit of glass 2. The inner strip 5 is placed against the inner surface layer 11 and the unit of glass 2.

Fig. 2 shows that the unit of glass 2 comprises an outer pane of glass 12 and an inner pane of glass 13. The outer pane of glass 12 is intended to face away from a building and the inner pane of glass is intended to face towards the inside of a building. The unit of glass 2 comprises a frame part 14 placed between the outer pane of glass 12 and the inner pane of glass 13. The frame part 14 extends along the periphery of the panes of glass and is sealed against the panes of glass 12, 13 with a suitable sealant (not shown).

Fig. 2 shows that the unit of glass 2 stands on a block 15 between the unit of glass 2 and the door 1 in the direction of extension of the door. The opening 3 of the door is normally made large enough to produce an allowance or slit between the unit of glass 2 and the periphery of the opening 3. The block 15 has the purpose of placing the unit of glass 2 correctly in the opening 3. Multiple blocks 15 may be placed around the opening 3 in order for the unit of glass 2 to end up in the desired place during application in the opening 3, for instance concentrically in the opening 3.

The outer strip 4 is designed with a first part 16 and a second part 17. The first part 16 is placed against the outer surface layer 7 and the second part 17 is placed against the outer pane of glass 12. Fig. 2 shows that the unit of glass 2 is lowered into the door 1 in relation to the outer surface layer 7. The outer strip 4 is therefore designed with an angle 18 between the first part 16 and the second part 17. The angle 18 admits that the outer strip 4 can exert pressure on both the outer surface layer 7 and the outer pane of glass 12 of the unit of glass 2. Fig. 2 shows that an outer sealing strip 19 is placed between the second part 17 of the outer strip 4 and the outer pane of glass 12. The outer sealing strip 19 is preferably made of a flexible material that deforms under pressure. When the second part 17 of the outer strip 4 presses against the outer sealing strip 19 the outer sealing strip 19 is deformed against the outer pane of glass 12 in such a way that a watertight seal is formed between the outer strip 4 and the unit of glass 2.

The inner strip 5 is designed with a third part 20 and a fourth part 21. The third part 20 is placed against the inner surface layer 11 and the fourth part 21 is placed against the inner pane of glass 13. Fig. 2 shows that the unit of glass 2 is lowered into the door in relation to the inner surface layer 11. The inner strip 5 is therefore designed with an angle 22 between the third part 20 and the fourth part 21. The angle 22 admits that the inner strip 5 can exert pressure on both the inner surface layer 11 and the inner pane of glass 13 of the unit of glass 2. Fig. 2 shows that an inner sealing strip 23 is placed between the fourth part 21 of the inner strip 5 and the inner pane of glass 13. The inner sealing strip 23 is preferably made of a flexible material that deforms under pressure. When the fourth part 21 of the inner strip 5 presses against the inner sealing strip 23 the inner sealing strip 23 is deformed against the outer pane of glass 13 in such a way that a watertight seal is formed between the inner strip 5 and the unit of glass 2.

Fig. 2 shows that the inner strip 5 has a through-and-through channel 24 in which a screw 26 is screwed in. Fig. 2 also shows that the outer strip 4 has a hole 25 in which the screw 26 is screwed in. The screw 26 pulls the outer strip 4 towards the inner strip 5 in such a way that the outer strip 4 pushes against both the outer surface layer 7 and the outer pane of glass 12, at the same time as the inner strip 5 pushes towards both the inner surface layer 11 and the inner pane of glass 13. Along the whole of the outer and the inner strip 4, 5 a number of screws 26 are screwed in, in the same way as described in connection to fig. 2.

The description of the door in connection to figs. 1 and 2 is also valid for the invention described in connection to figs. 3-12a and 12b, in everything except for the screws as fastening means. Fig. 3 schematically shows a cross section of the outer strip 4 and the inner strip 5 as shown in fig. 2, but with a joining device 30 according to the invention. Fig. 3 shows that the inner strip 5 comprises a through-and- through channel 24 extending essentially horizontally. The joining device 30 comprises a male element 30a and a female part 32. The male element 30a comprises in a first end section a male part 31 and in a second and opposing end section a stopping device 35. The male part 31 is inserted into the channel 24 in the direction R1 towards the funnel-shaped orifice 27 in the outer strip 4. The female part is in the shape of a unit comprising a through- and-through opening 32a and a clamping device 32b. The female part 32 is arranged inside the hole 25 in the outer strip 4 and fastened to the material that defines the hole 25. The male part 31 and the female part 32 are arranged to admit that the male part 31 may be moved in the first direction R1 in to the hole 25 without that the female part 32 engages with the male part but is arranged to prevent the male part 30a from being moved in a second direction R2, opposite the first direction, out of the hole 25 through that the clamping device 32b is arranged to engage with the male part 31 as the male element 30a has been inserted into the hole 25 so that the joining bond has been formed and forces thereby have arisen between the outer strip 4 and the inner strip 5 trying to pull the joining bond apart.

Fig. 3 shows that the outer strip 4 comprises blind holes 25 that each one are equipped with a funnel-shaped orifice 27 intended to guide the male elements 30a towards the holes 25. With "blind hole" is meant that the hole is not through-and-through but has only one opening. The funnel-shaped orifice 27 is intended to guide the male element 30a towards the hole 25 as the male element 30a is inserted into the hole 25 from the inner strip 5.

Fig. 3 shows that the channel 24 has a funnel-shaped orifice 28 to guide the male element 30a into the channel. However, it has to be mentioned that the funnel-shaped orifice 27 in the hole 25 in the outer strip 4 and the funnel- shaped orifice 28 in the channel 24 in the inner strip 5 can be omitted if the male element 30a is designed with a pointed end section for guidance (see fig. 6) or if the male element 30a has an essentially smaller diameter/circumference than the hole 25 and the channel 24 respectively.

Fig. 3 shows that the funnel-shaped orifice 28 of the inner strip 5 faces the same way as the funnel-shaped orifice 27 in the outer strip 4 since the inner strip 5 has a through-and-through channel 24 that the male part 31 will be inserted through in a direction towards the hole 25 in the outer strip 4. In order for a joining bond to form between the outer strip 4 and the inner strip 5 the male element 30a must attach to both strips and absorb forces that wants to pull the male element 30a from the hole 25 and the channel 24 respectively. The forces arise when the strips 4, 5 is in contact with the door and/or the unit of glass under pressure. The male part 31 , as mentioned earlier, absorbs via the female part 32 forces in the hole 25 in the outer strip 4; the stopping device 35, at the same time, absorbs forces from the inner strip 5 that prevents the stopping device 35 and thereby the male element 30a from gliding through the channel 24. In fig. 3 the stopping device 35 is designed to fit into the funnel-shaped orifice 28 in the inner strip 5, but the stopping device 35 may have a different design. As an example can be mentioned that, when the funnel-shaped orifice 28 is missing and the channel is essentially uniform, the stopping device 35 can be arranged with a head that is in contact with the outer side of the inner strip 5 or that automatically countersinks through for instance rotation.

The stopping device 35 can be used to apply an external force on the male element 30a in order to bring the male element in the direction R1 towards the female part in such a way that the stopping device 35 is in contact with the inner strip 5 and forces it in a direction towards the outer strip 5, whereupon the joining device 30 prevents the strips from moving in a direction from each other as the male part 31 has passed through the opening 32a in the female part 32. The external force is necessary in order for the joining bond to be so tight that the strips 4, 5, during glazing, will seal against the door and the unit of glass. In order for such a tightness to occur forces must arise between the outer strip 4 and the inner strip 5 trying to pull the joining bond apart. The forces that arise depend on that the door and the unit of glass prevents the strips from moving freely towards each other, but as the strips come in contact with the door or the unit of glass a pressure between the door/unit of glass arises and the respective strips. The pressure increases the more the strips are pressed against each other. The external force makes sure that the pressure increases and sealing takes place. Often relatively soft sealing strips between the strips and the door and/or the unit of glass are used that contribute to an elastic effect acting to pull the strips apart. The discussion above concerning the need of an external force giving rise to the forces that arise between the strips in order to create tightness is universal for the invention and shall be read together with all of the examples described with the figs. 3-11. The external force does not need to arise through that the male element comprises a stopping device that absorbs the forces, but the external force can be applied directly on the strips.

Fig. 4 schematically shows a cross section along the line B-B in the section A, of a lower part of the unit of glass 2 attached to the door according to a second example of the invention. A difference between the examples shown in fig. 3 and fig. 4 is that in fig. 4 the inner strip 45 comprises a blind hole 29 instead of the channel 24 shown in fig. 3. Another difference is that the inner strip 45 also comprises a female part 32 in connection to the hole 29. The male element 30a is in the shape of a plug 30a comprising a male part 31 for attachment in the female part 32 in the hole 25 in the outer strip 4 and another male part 31 for attachment in the female part in the hole 29 in the inner strip 45. The two male parts 31 are arranged on opposing end sections of the male element 30a. The plug 30a in fig. 4 can be a cylindrical unit, but may also have other cross sections than circular, for instance oval, triangular, square, polygonal etc. The plug 30a may also have different dimensions on the male parts 31 and the rest of the plug 30a. In fig. 4 the male parts 31 constitute a predetermined length of the plug 30a. The predetermined length depends on the depth of the holes 24, 25 and the distance between the strips 4, 45, i.e. the thickness of the unit of glass.

Fig. 4 shows that the outer strip 4 comprises holes 25 that each one is equipped with a funnel-shaped orifice 27 intended to guide the plug 30a towards the holes 25 in the outer strip 4. The funnel-shaped orifice 27 is intended to guide the plug 30a towards the hole 25 as the plug 30a is moved in the direction from the inner strip 45 towards the outer strip 4.

Fig. 4 shows that the inner strip 45 comprises a hole 29 extending essentially horizontally. The inner hole 29 has a funnel-shaped orifice 28 intended to guide the plug 30a towards the inner hole. However, it shall be mentioned that the funnel-shaped orifice 27 in the hole 25 of the outer strip 4 and the funnel-shaped orifice 28 in the hole 29 in the inner strip 45 can be omitted if the male element 30a is designed with a pointed end section for guidance (see fig. 6) or if the male element 30a has a smaller diameter/circumference than the hole 25 and the channel 24 respectively.

During glazing of the door 1 , the male element 30a is suitably first applied in the female part in the inner strip 45 or in the female part of the outer strip 4, where after the strips 4, 45 are moved towards each other in such a way that the free male part 31 engages with the female part of the opposing strip 4, 45 whereupon the desired joining bond is formed. In order for an optimal joining bond to be formed the strips 4, 45 are pressed against each other in such a way that the strips 4, 45 seal against the door 1 and/or the unit of glass 2.

Fig. 5 schematically shows a cross section of the outer strip 4 and the inner strip 45 shown in fig. 4. Fig. 5 shows that the outer strip 4 comprises holes 25 that each one is equipped with a funnel-shaped orifice 28. The funnel-shaped orifice 28 is intended to guide the plug 30a towards the hole 29 in the inner strip 45 as the plug 30a from the beginning is applied to the hole 25 of the outer strip 4. Fig. 5 shows that the male element 30a comprises a male part 31 arranged in each end section of the male element and that a male part 31 is engaged with one of two female parts 32 in the hole 25 of the outer strip 4 and that the second male part 31 shall be inserted into the hole 29 of the inner strip 45 to engage with two female parts 32 arranged in the hole 25. When the strips 4, 45 are pressed against each other the male parts 31 will engage with both of the respective female parts. Two female parts 32 in each hole 24, 25 has the advantage that the male element 30a not is able to wiggle in the hole and give rise to malpositioning that can impair the joining bond between the strips 4, 45.

Fig. 6 schematically shows a cross section of an outer strip 4 and an inner strip 45 according to a third example of the invention. Fig. 6 is identical to fig. 5, but with the difference that the funnel-shaped orifices are missing and that the holes therewith has an essentially uniform design. The bottom of the holes can however be chamfered if a drill or similar is used, but this is of no significance to the invention. Fig. 6 shows that a first adapter 40 is arranged in the hole 25 in the outer strip 4 and that a second adapter 41 is arranged in the hole 29 of the inner strip 45. Each of the adapters in fig. 6 comprises two female parts 32. The adapters 40, 41 can be arranged in the holes 25, 29 through force fitting, threading or any other suitable joining technique. Each adapter 40, 41 comprises a hole 42, 43 being adjusted after the female part 32 and the male part 31 in such a way that the male part 31 can be inserted into the female part 32 as the outer strip 4 is to be fastened to the inner strip 45. The adapter is thus arranged to house the female part and/or the male part.

As the female part 32 is arranged inside the adapter 40, 41 the holes 42, 43 of the adapter 40, 41 are adjusted to fit the opening 32a of the female part

32. The holes 42, 43 of the adapter 40, 41 are preferably arranged coaxially with the opening 32a in the female part 32. Concerning the description of the function of the male parts 31 and female parts 32 of the joining device 30 reference is made to the description of figs. 4 and 5.

Fig. 6 shows just as fig. 5 that a male part 31 engages with one of two female parts 32 in the hole 29 of the inner strip 45 and that the second male part 32 is to be inserted into the hole 25 of the outer strip 4 to engage with the female parts 32 arranged in the hole 25. When the strips are pressed against each other all of the female parts 32 will be engaged with the male parts 31 of the male element 30a.

Fig. 7 schematically shows a cross section of an outer strip 4 and an inner strip 45 according to a fourth example of the invention. Fig. 7 is identical to fig. 6, with the difference that in fig. 7 the male element 30a comprises outer threads on one of its end sections and that the second adapter 41 comprises inner threads in its hole 43 intended to receive the threaded portions of the male element 30a for joining. When the male element 30a is fastened to the second adapter 41 , the holes 43 of the second adapter are adjusted to fit the male element 30a in such a way that the male element 30a is attached to the adapter without being the weak link of the joining bond The second adapter 41 may thus comprise threads for fastening of the male element 30a via the corresponding threads of one end section of the male element 30a or may be joined through force fitting or any other suitable joining method. In fig. 7 the one end of the male element 30a not being threaded is intended to join bond with the female parts 32 of the first adapter 40 of the outer strip 4. However, it shall be mentioned that the reverse may be true, i.e. that the male element 30a can be attached to the first adapter via threads, force fitting or similar. The other end of the male element 30a then comprises the male part intended to engage with the female parts 32 arranged in the second adapter 41.

In fig. 7 the first adapter 40 of the inner strip 4 may comprise threads in the hole 42 adjusted for the corresponding outer threads of the female part 32 for attachment of the female part 32 inside the first adapter 40. The female part 32 can otherwise be fastened inside the adapter by means of force fitting or similar. The first adapter 40 can also be divided into a number of parts between which the female parts 32 can be arranged and fastened as the parts are assembled into the first adapter 40. The first adapter 40 are then fastened into the hole 25 in the outer strip 4.

Fig. 8 schematically shows a cross section of an outer strip and an inner strip according to a fifth example of the invention. Fig. 8 is identical to fig. 5 but with the difference that the funnel-shaped orifices are missing and that the holes therewith has an essentially uniform design. The bottom of the holes can however be chamfered if a drill or similar is used, but this is of no significance to the invention. Concerning the description of the function of the male parts 31 and female parts 32 reference is made to the description of the figs. 4 and 5. Fig. 6 shows that the male element 30a comprises a first end section 35 and a second end section 36. The first and the second end section 35, 36 are chamfered for guidance of the male element 30a into the respective holes 25, 29.

Fig. 9 schematically shows a cross section of an outer strip and an inner strip according to a sixth example of the invention. In fig. 9 it is shown that the joining device 30 comprises a distancing element 37 comprising a hole 37a comprising two female parts 32. In fig. 9 it is shown that the distancing element 37 is attached to the outer strip 4, but the distancing element may alternatively be fastened in the outer strip 45.

The one end 37b of the distancing element 37 may be fastened directly into the hole 25 of the outer strip 4 (or the inner strip 45) by means of threads or force fitting or similar, but may also be fastened into such an adapter as is shown in figs. 6 and 7 via threads or through force fitting or any other suitable way. In fig. 9 it is shown that the distancing element 37 extends from the outer strip 4 in such a way that the hole 37a in the distancing element is located outside the outer strip 4. The hole 37a in the distancing element may however at least partly be located inside the outer strip 4, i.e. may be a part of the one end 37b of the distancing element 37 that is fastened to the outer strip 4. If the distancing element 37 instead is fastened to the inner strip 45 the above description is valid but the outer strip 4 is replaced by the inner strip 45. Concerning the description of the function of the male parts 31 and the female parts 32 of the joining device 30 reference is made to the description of figs. 4 and 5.

Fig. 10 schematically shows a cross section of an outer strip and an inner strip according to a seventh example of the invention. Fig. 10 shows that the outer strip 4 and the inner strip 45 comprises a male element 30a comprising a male part 31 extending from the outer strip 4 and the inner strip 45 respectively. Each male element 30a comprises a section that is fastened in the outer strip 4 and the inner strip 45 respectively. In fig. 10 it is shown that the respective male elements 30a are fastened in the outer strip 4 and the inner strip 45 respectively via an adapter according to figs. 6 and 7. In fig. 10 it is shown that the joining device 30 comprises a connector 38 comprising two opposite holes 39. In fig. 10 it is shown that the connector 38 comprises two female parts 32 in connection to each respective hole 39, but both one female part or more than two are possible. Concerning the description of the function of the male parts 31 and the female parts 32 of the joining device 30 reference is made to the description of figs. 4 and 5.

Fig. 11 schematically shows a cross section of an outer strip and an inner strip according to an eighth example of the invention. Fig. 11 shows that the female part 32 is arranged inside the hole 25 of the outer strip 4 and the hole 29 of the inner strip 45. In fig. 11 it is shown that the female parts have been secured with the aid of plugs 44 comprising channels 44a. The channels 44a are preferably coaxially aligned with the opening 32a of the female part 32 or larger than the opening 32a to admit the male part 31 to pass through the opening 32a of the female part 32. The plugs 44 can be fastened in the hole 25, 29 by means of force fitting, threads or any other known method for fastening plugs into holes. When a female part 32 is used a plug 44 on each side of the female part 32 is needed. The plug 44 facing the bottom of the hole constitutes a distancing device between the bottom of the hole and the female part 32 so that the male part 31 can pass the female part without touching the bottom of the hole 25, 29. The plug 44 facing out from the opening of the hole 25, 29, i.e. in the direction that the male part 31 is inserted into the hole 25, 29, keeps the female part in place so that the female part 32 can constitute part of the joining device 30 without being pulled out as forces exist that wants to pull the joining bond apart. In fig. 11 it is shown that two female parts 32 are used in the holes 25, 29 respectively. When more female parts 32 are being used in the hole 25, 29 the female parts are separated by further plugs 44 comprising through-and-through channels 44a. In fig. 11 it is shown that a first plug 44 is placed between the bottom of the hole 25, 29 and the first female part 32 and that a second plug 44 is placed between the first female part 32 and the second female part 32 and that a third plug 44 is placed between the second female part 32 and the opening of the hole 25, 29. The third plug is arranged to keep the female parts 32 in place in the hole 25, 29 so that the joining bond does not release. An advantage with having two female parts is that the male part can not be slanted in the hole as the two clamping devices is at a distance from each other and removes the degree of freedom for the male part to rotate in a radial direction along an opening in a female part. Concerning the description of the function of the male parts 31 and the female parts 32 of the joining device 30 reference is made to the description of figs. 4 and 5.

Fig. 12a schematically shows an example of a female part 32 in one of the joining devices 30 according to the invention according to one of the figs. 3- 11. The female part 32 comprises an opening 32a, a clamping device 32b and a female body 32d. The clamping device 32b comprises lips 32c with a first end 33 and a second end 34 that during engagement extends along the length extension of the male part 31 and that at least in its first end 33 is attached to the female body 32d and whose second end 34 is arranged to engage with the male part 31 as the joining device 30 is influenced by forces trying to separate the joining bond. The part of the joining bond 32 that lacks the clamping device 32b is denominated female body 32d and may have any possible shape depending on how the female part 32 is secured in position in the hole. The female body 32d may comprise a flange 32e. The flange 32e is positioned outside of the clamping device as seen from the centre of the female part 32. The flange 32e may be used to clamp up, secure by screws or in any other way secure the female part 32 in the hole. The flange may thus comprise threads in order to be able to be threaded into the hole to a desired position. In figs. 3-11 it is shown that the flange has a greater diameter/extension than the hole that the female part is arranged in conjunction with. In the hole, there is in a corresponding way a cavity or similar that admits that the flange can engage with the surrounding material in the hole. The flange may however be arranged on the envelope surface of the hole, for instance when an adapter or a distancing element is used. The flange can be arranged on the envelope surface by means of welding, soldering, force fitting, gluing, shrinking or any other known method for fastening devices in to holes.

Fig. 12b schematically shows a female part 32 seen along the line XIb-XIb in fig. 12a together with a male part 31. The arrow in fig. 12b shows the direction of motion of the male part 31 as it is inserted into the female part to form the joining bond. Fig. 12b shows that the size of the male part 31 exceeds the distance between opposing clamping devices 32 but is smaller than the size of the opening 32a of the female part. The male part 31 can during insertion pass the opening 32a to thereafter affect the clamping devices 32b with a force that causes the clamping devices 32b to fold or in any other way take form after the male part 31 as the male part is moved in the direction of the arrow into the hole described in conjunction to any of the figs. 3-11. Fig. 12b shows that the clamping device 32b is arranged in an angle α relative to the axial extension of the male part 31. The radial extension of the male part 31 coincides with the direction of motion as the male part 31 is inserted into the hole. The angle α has the effect that as the male part is moved in a direction opposite the direction of the arrow, i.e. out of the hole, the clamping device 32b is affected via friction between the male part 31 and the clamping device 32b in such a way that the clamping device 32b absorbs the kinetic energy and prevents the male part 31 from moving in a direction out of the hole. The angle α depends on the material in the male part and the material in the female part and is to be adjusted depending on the demands placed on the strength of the joining bond.

The invention is not limited to what is shown in figs. 1-12a and 12b, but may be varied. As an example it can be mentioned that the male element 30a may be attached to the inner strip or the outer strip before joining takes place during glazing. The part of the male element 30a that is not attached shall then be inserted into a hole of the opposing strip and the male part shall then engage according to what has been described above to secure the joining bond. Another example is that the male element 30a may have one or both of the end sections chamfered/pointed for guidance at the same time as one or both of the holes may have a funnel-shaped orifice, for guidance of the male element 30a towards the hole or holes. In the figs. 5-11 it is shown that there are two female parts mounted in each hole, but it may be a female part according to figs. 3 or 4 or more than two.
