&igr; Description

The invention relates to thermally separated light metal composite profiles for

4 Windows and doors, whereby the composite profiles are made of a light metal

.-, inner shell and a light metal outer shell, which are separated from each other by at least two insulating bars, so that the inner and outer

7 shells are arranged parallel and spaced apart. Preferably

< Aluminium is used as a light metal in such profile constructions.

11 This arrangement creates a hollow section extending in the axial direction of the composite profile.

n one hand and the insulating bars separating these aluminium profiles on the other hand

u is formed. The connection between the aluminum shells and the

is arranged between insulating bars preferably consists of a

i It is also known that the central rebate between the frame and the sash of

&zgr; Windows made of the above-mentioned aluminum composite profiles provide thermal

;, can represent a technical weakness that leads to heat losses.

5 In known window systems made of aluminium composite profiles, the

f, central fold consisting of a chamber which extends over the entire construction depth

&iacgr;&ogr; sash profile is formed. The spatial geometry of such center folds with her-

11 conventional central sealing profiles prove to be thermally unfavourable

12 stig, since the free cavity cross-sections of the simply divided central fold ! ? hollow chamber are large and promote convection and radiation and u thus heat loss.

&iacgr;&ogr; According to the current state of the art, central seals have the function of

!; a wind barrier and a seal on the room side against weather side in the

&igr;* Construction penetrated moisture. The thermal insulation properties

tv conventional center seals, preferably made of permanently elastic EPDM,

2o are not optimal due to the material, not least because elastic center seals

z: functions are designed.

u Heat conduction through central sealing bodies according to the state of the art, which

25 their material properties for permanently reliable sealing properties

&udiagr;&agr; is taking place to an extent that could definitely be improved

The present invention is therefore based on the object of improving the heat

i to improve the technical properties of center folds so that

a on the one hand, the free cavity cross-sections in the center rebate cavity and

thus reducing heat losses through convection and radiation

&igr; and on the other hand the heat conduction through the central sealing plane noticeably

.; is reduced, so that the thermal insulation properties of corresponding windows

r-, ster constructions made of aluminum composite profiles can be measurably improved.

8 The object is achieved according to the invention in that an insulating profile 1 in the

« Center rebate is provided, which is assigned to the frame, to which

H) connected window, a sealing profile 13 assigned to the sash profile

Ii, whereby the insulating material according to the invention assigned to the frame

i; profile 1 essentially has the properties necessary to improve the

&igr;&idigr; Thermal insulation properties of a window in the center rebate and the inventive

u sealing profile 13 arranged on the sash side according to the instructions, the function of the

is wind barrier and the sealing on the room side against weather side in the

U: Moisture that has penetrated the construction.

i« In order to optimally solve the problem underlying the invention, it is desirable

!v It is worth noting that an insulating profile 1 according to the invention has a cross-sectional area

20, which is the cross-sectional area of a sash frame associated

z\ sealing profile 13 significantly, preferably several times,

22 whereby the height of the insulation profile 1 corresponds almost to the height of the middle fold.

2! and the height of the sealing profile 13 in relation to the height of the

24 insulation profile 1 is chosen as low as possible. This ensures

25 that the division of the central rebate into at least two chambers is achieved primarily 2ii by an insulating profile 1 which has a lower thermal conductivity &zgr;; than the sealing profile 13 assigned to the sash frame.

20.01.97

W. Hartmann & Co. {GmbH & Co.), Hamburg

The small cross-sectional area and the low height of the sealing profile 13

&igr; also proves to be highly advantageous in processing, as it

&zgr; small dimensions in the bending direction can be guided all the way around corners and complex work for the production of vulcanized sealing

4 frames can be omitted.

&lgr; According to the technical teaching of the invention, the insulation profile 1 has the following

- have the properties described below.

« In a preferred embodiment, the insulation profile 1 has a

... closed profile body 2, preferably made of closed-cell, foamed

1 1 tem plastic, which is covered in its edge areas with an outer skin 3.

13 hen, whereby profile body 2 and outer skin 3 have different Shore hardness 15 and the Shore hardness of the outer skin 3 exceeds the Shore hardness of the profile body

14 pers 2. A higher Shore hardness of the outer skin 3 proves to be advantageous in production and handling, since the stability of the insulation profile 1 is thereby increased and, in addition, moisture and condensate on the side of an insulation profile 1 according to the invention facing the weather side can be more easily drained to the outside.

20 According to the technical teaching of the present invention, it is also conceivable that the profile body 2 has one or more cavities which extend continuously in the longitudinal direction of the profile body 2. Such cavities

21 preferably have a circular cross-section, but can also have any

24 ge other cross-sectional shapes, such as rectangular, rectangular with tapered

25 rounded edges, oval, ellipsoid or other geometric shapes.

20.01.97

W. Hartmann & Co. (GmbH & Co.), Hamburg

It proves to be advantageous if the profile body 2 and the outer skin 3 are connected to one another in one piece, for example by realizing the one-piece connection by means of coextrusion.

However, it is also conceivable to cover an insulating profile 1 according to the invention with an outer skin 3 after its production, for example by wrapping, gluing, vulcanization or other suitable methods and to assign the composite thus produced to the frame according to the invention.

An insulating profile 1 according to the invention is made of a material with low thermal conductivity, preferably heat-insulating rigid foam, in order to reduce the disadvantageous heat losses due to thermal conduction.

In a preferred embodiment, an insulating profile 1 according to the invention has a substantially rectangular cross-section, the profile body 2 being stepped on the room side and having a stop surface 7 against which the sealing lip of a sealing profile 13 rests when the sash is closed, which is assigned to the sash frame according to the invention.

In the following, preferred embodiments of the present invention are presented and explained using drawings.

In Fig. 1, an insulating profile 1 according to the invention is shown on an enlarged scale for clarity. The insulating profile 1 consists of the profile body 2, which has a substantially rectangular cross-section. On its underside, a profile body foot 4 is formed on the profile body 2, which is designed to fix the insulating profile 1 to the frame. For this purpose, it has locking lugs 9 and 10 on both sides, which serve to clamp the connection to the frame.

W. Hartmann & Co. (GmbH & Co.), Hamburg

&igr; The room-side part of the profile body 2 has a gradation through which

2 a stop surface 7 and a room-side step 8 are formed. The embodiment according to Fig. 1 has a stop surface running in the window plane.

4 striking surface 7, but it is also conceivable that the striking surface 7 in

3 is preferably inclined at an acute angle to the window plane. It is obvious that the exact angular position of the stop surface 7 depends on the indicated order of magnitude from the geometry of the central sealing system and

&kgr; of the sealing profile 13 in order to ensure reliable and permanent sealing of the central sealing level.

11 In order to meet the requirements underlying the invention,

&igr;.; it is desirable to adjust the room-side gradation of the profile body 2 only

&igr; i far that the room-side step 8 allows the rotary movement of the wing

(4 frame is not obstructed. The respective height of the room-side step 8 results

i< is therefore determined from the profile geometry of the underlying window system

ic and can therefore vary.

&igr;« The top of the insulation profile 1 has a slope 6 on the weather side, which

■&lgr;· Water is used. In order not to increase the cross-sectional area of the insulation profile 1 unnecessarily,

2i, it is desirable to change the angle of the slope 6 only as far

zj to deviate from the perpendicular to the window plane so that an unhindered

2.&Idigr; reduced drainage of moisture is possible. According to the technical

u However, the teaching of the invention also allows embodiments to be conceivable which provide for stronger bevels or do without them altogether, provided that other suitable

The entire development surface of the insulation profile 1 is provided with an outer skin 3 &igr;, which preferably has a greater Shore hardness than the profile body

&igr; 2. A harder outer skin 3 gives an insulating profile 1 according to the invention

s advantageous properties that have a positive effect on processing and handling

4. The increased stability also gives the insulation profile 1

5 higher resistance to wear and tear.

? It is also advantageous to combine the profile body 2 and the outer skin 3

> in one piece, for example by coextrusion. This saves complex work steps during processing. However, it is certainly possible to apply a firmer outer skin to the profile body 2 after it has been prepared.

&pgr; This can be done by gluing, wrapping, vulcanization or similar.

n suitable composite technology processes.

&igr;? shown in installation situation.

&igr;? Fig. 2 shows a preferred form of assignment of an inventive

1$ insulation profile 1 to a frame made of aluminum composite profiles. The

2&ugr; Fig. 1 designated locking lugs groove rear hooks formed on the frame

its permanent elasticity allows the positive connection between insulating profile 1 and the frame to be realized by slightly pressing the locking lugs 9 and 10 together, whereby the locking lugs 9 and 10 return to their starting position after being inserted into the groove undercuts on the frame and transition into the positive connection with the frame.

This simple installation method leads to thermal improvements without increased assembly or manufacturing costs, and it also ensures problem-free and quick dismantling of corresponding insulation profiles 1.

It is also possible to insert the insulation profile 1 into its final position in the frame in the longitudinal direction.

It is also conceivable to apply an insulating profile 1 according to the invention with or without a positive clamping connection to the insulating web on the frame side using other connection techniques and to secure it permanently, for example by bonding with material-compatible adhesives.

The slope 6 shown in Fig. 2 enables condensate or rainwater that has penetrated from the weather to flow into the antechamber of the frame and from there to the outside. The harder outer skin 3 has a beneficial effect on this function due to its dimensional stability. It can be seen from this that an insulating profile 1 according to the invention not only provides increased thermal insulation, but also takes into account the needs of structural moisture protection.

According to the technical teaching of the present invention, a sealing profile 13 is assigned to the sash frame, the sealing profile 13 with its

25 has a particularly beneficial effect on reducing thermally undesirable convection .

The low thermal conductivity of the preferred material for the production of the invention

1 appropriate insulation profiles 1 used rigid foam further reduces

2 the heat loss through heat conduction in the insulation zone area of the middle fold. This effect is favorably influenced by the fact that the

&agr; Insulation profile 1 extends in height almost up to the wing-side insulation bar 11

f &igr; As stated above, the reduction of heat conduction is achieved by the

&agr; Middle fold is additionally advantageous due to the size ratio of the cross

A further advantageous embodiment of an insulating profile 1 according to the invention is shown in Fig. 5 on an enlarged scale for clarity. The technical features of the insulating profile 1 can be taken from the explanations for Fig. 1 with Fig. 4; a repetition is unnecessary at this point for the sake of brevity.

However, in the embodiment according to Fig. 5 there is an additional feature that advantageously influences the thermal insulation properties of the insulation profile 1. The harder outer skin 3, which surrounds the profile body 2 according to the invention, is additionally provided with a coating surface 24. The coating surface 24 preferably consists of a film coating, but according to the teaching of the invention it can also consist of a lacquer coating or be vapor-deposited.

The coating surface 24 has only a low emissivity in order to prevent heat losses due to heat radiation through the central fold as far as possible, or at least to reduce them to a considerable extent. The coating surface 24 preferably surrounds the entire development surface of the profile body 2, but it is also conceivable that only certain partial surfaces of the development are provided with a coating surface 24.

2i In Fig. 6, an insulation profile 1 in the embodiment according to Fig. 5 is shown in installation

n tuation is presented.

The findings made in relation to Fig. 2 and Fig. 4 can in principle be used analogously to consider the situation in Fig. 6. Furthermore , it is clear from Fig. 6 that the functional unit of insulation profile / sash frame-side sealing profile completely bridges the entire height of the middle rebate in the 2ü insulation zone area of the construction and thereby

i te blocked to the weather side. The coating surface 24 low emissivity,

/ which surrounds the insulation profile 1, further increases the radiant heat losses

down.

5 Fig. 7 shows a further advantageous embodiment of an inventive

6 ßen insulation profile, shown in enlarged scale for clarity.

&ugr; On the surface of the room-side step, referred to as the stop surface 7 in the previously described embodiments, the insulation profile 1 has a

&kgr;- sealing body 26, to which a sealing lip 25 is formed. The connection

&pgr; between insulation profile 1 and sealing body 26 is preferably one-piece

ü, for example by coextrusion. This form of connection means

ü Economic advantages due to uncomplicated and time-saving installation

!4 of production.

i&rdquor; As can be seen from Fig. 7, the sealing body 26 has only a small transverse

17 cut area, preferably smaller than the cross-sectional area of the sealing lip

i« pe 25, so that sealing lip 25 and sealing body 26 together have a small

tv cross-sectional area and this is significantly smaller than the

so cross-sectional area of the insulation profile 1. This results in a favorable

v ratio between the heat-insulating material of the insulation profile 1 on the one hand and

z: on the one hand and sealing body 26 and sealing lip 25 on the other hand, whereby heat

i\ heat losses due to heat conduction in the center fold area can be reduced.

2- Fig. 8 shows an embodiment of the insulation profile 1 according to Fig. 7, in which

2<, the profile body 2 does not consist of a solid hard foam profile, but

.:: has at least one, in Fig. 8 two, cavities 29. The cavities 29

28 preferably have a circular cross-section, but can also have any other

20.01.97

W. Hartmann & Co. {GmbH & Co.), Hamburg

have any cross-sectional shape, such as rectangular, oval, ellipsoidal or the like. The above-mentioned cavities 29 have the advantage that insulation profiles 1 provided with them become more flexible and are therefore easier to process.

Additional corner brackets that can be pressed into these cavities stabilize the corner joints of mitred and glued pieces.

In Fig. 9 there is an insulation profile 1 in the embodiment according to Fig. 7, shown in the installation situation in a window made of aluminum composite profiles. The insulation profile 1 essentially has the material properties and profile geometry described above. A hollow body 27 extending into the center fold is formed on the insulation web 11 of the sash, which preferably has a rectangular cross-section. The wall of the hollow body 27 facing the weather side forms a stop web 28 against which the sealing lip 25 strikes when the sash is in the closed position.

The illustration in Fig. 9 shows that the sealing body 26 and the sealing lip 25 are arranged in a virtually convection-free center rebate channel 30 and, when the window sash is in the closed position, do not experience any significant convective inflow of heated air from the room-side center rebate chamber 17.

The support surface 7 described above has, in the case of an insulating profile according to Fig. 10, a groove-shaped sealing receptacle 32 into which & a sealing body 26 with a molded-on sealing lip 25 can be introduced.

As described in Fig. 3, the profile body foot 4 is provided with a support groove 19

&igr; which has a curved groove base 31. The curved groove base
