Description

The invention relates to a strand-like wing groove seal for windows and doors made from wood according to the preamble of claim 1.

DE 296 09 976 UI discloses a wing groove seal. A sealing head, constructed as a hollow profile or section, with a sealing web and a contact or bearing web, which in the loaded state engage on the surface to be sealed, as well as with an upper transverse web with a V-shaped construction and which bends in under closing pressure, is made from a softer, elastic material, particularly a thermoplastic elastomer, whereas a profile back (or upper surface) and a lower transverse web of the sealing head, together with a sealing foot with at least one retaining lip and a cover lip are made from a harder, less expensive material, e.g. ethylene vinyl acetate.

The processing temperatures of the thermoplastic elastomer and the ethylene vinyl acetate are advantageously no more than 50°C apart and the manufacture of the relatively inexpensive wing groove seal can take place by coextrusion.

DE 44 02 604 Cl describes a wing groove seal, which has a profile back with an outer reinforcing wall. The outer reinforcing wall is made from a much harder material than the remaining wing groove seal and extends up to the foot-side end of the sealing foot. At the head side it terminates at a distance from the head-side end and in said head-side end made from the softer material is placed a reinforcing strand of the much harder material.

The reinforcing wall and the head-side reinforcing strand are intended to permit a precise implementation of the mitre angles around a frame corner for which the strand-like wing groove seal IE 070 175 is in each case provided with a V-shaped mitre cut or with a corner notch, which only extends up to the upper transverse web. The sealing function in the mitre angles and frame corners must be ensured by a very tight connection of the cut edges and by a very planar, tight engagement of the profile back, particularly in the upper end region.

The object of the invention is to provide a strand-like wing groove seal, which ensures the necessary sealing, particularly in the corner wraps by means of a corner notch and/or mitre cut and which can be simultaneously inexpensively manufactured and fitted.

According to the invention this object is achieved through the features of claim 1. Appropriate and advantageous developments are given in the subclaims and the description relative to the drawings .

It has been found that a sealing profile, which is particularly suitable for wing groove seals for windows and doors and a sealing head on a profile back, as well as a sealing foot with at least one retaining lip for anchoring in a slot or groove and a cover lip for covering the slot, can be fitted in extremely advantageous manner by means of corner notches around the frame corners of a window or a door and the necessary sealing action and engagement is provided both in the area of the sealing head with its sealing areas and in the area of the profile back and in particular In the upper area, if the sealing head is made from a foam material in areas having a sealing function. The profile back, sealing foot and cover lip, which is formed between the sealing foot and the sealing head, are made from a harder material. According to the invention a scallop is formed on the side of the profile back remote from the sealing head and therefore on the outside of the profile back.

As a result of said scallop in the back of the sealing profile and ' 1' which is preferably provided at a distance from the upper end of If 07 0 1Z5 the profile back and which can be constructed in pipe-like manner or as a longitudinal channel with a roughly semicircular or Ushaped cross-section, there is a great improvement of the corner wrap in the case of a corner notch. It has been found that not only in the longitudinal areas, but also in the corner areas and in particular with the upper area of the profile back, the wing groove seal engages in a tight and stable manner on the correspondingly extended wall of the slot.

The whole-area, snug engagement of the profile back is achieved through the material combination, in conjunction with the scallop formed in a clearly defined manner. A detachment or tilting of the wing groove seal in the area of the sealing head with respect to the wing groove wall, a collection of dirt and moisture and the associated deterioration of the sealing action of the wing groove seal are prevented and a longer life with a constant sealing function is achieved.

It is particularly advantageous if a protuberance is formed at the upper end of the profile back and above the scallop. A particularly effective contact or engagement results from the cooperation of the protuberance with the scallop, which are located in the vicinity of the harder material of the profile back. This still applies if the wing groove seal with the sealing head and profile back with protuberance and scallop extend virtually up to a shoulder of the window or door wing frame.

It is advantageous that the scallop formed in the longitudinal direction of the wing groove seal passes with an upper wall into the protuberance.

The scallop can have a depth roughly corresponding to half the width of the remaining profile back. The protuberance, which also extends ap‘.the'Mdbgitudinal direction of the wing groove seal, can have a Width which is at a maximum twice that of the remaining profile back. The height of the scallop can be roughly the same «070175 as the height of the protuberance or somewhat greater and roughly complies with the ratio 1:1.5 to 2.

In principle, the protuberance can be in the form of a bead and project in semicircular, square or rectangular manner with rounded corners over the profile back.

In the area of the protuberance, to the inner wall of the profile back is connected the sealing head with an upper transverse web, which together with a sealing web and a contact web forms the areas with a sealing function and together therewith and with a lower transverse web and the profile back bound a cavity of the sealing head.

The sealing web, contact web and upper transverse web form the areas of the sealing head with a sealing function, which in the case of a closed window wing frame or door wing frame come into sealing engagement with a window or door frame and are deformed and move in the direction of the cavity. According to the invention these areas are made from a foam material, which is much softer than the harder material of the profile back, sealing foot and cover lip and has a corresponding Shore A hardness. The foam material can also be formed by expansion from the harder material and as a result is elastic.

It is advantageous if the foam material is externally provided with a dampproof membrane, which is appropriately formed by a coating, e.g. with a corresponding thermoplastic elastomer.

In the profile back and e.g. level with the cover lip can be provided a tension-proof insert, which constitutes the limit of the material expansion of the wing groove seal and is advantageous for the fitting of the seal.

The invention is described in greater detail hereinafter relative to the attached drawings, wherein show: ϋ 07 0 175 Fig. 1 A larger-scale according to the cross-section invention. of a wing groove seal Fig. 2 A larger-scale cross-section of a wing groove seal according to the invention having an alternatively constructed scallop and protuberance.

Fig. 3 A cross-section of a wing groove seal according to the invention fitted in a wooden window.

The wing groove seal 2 shown in fig. 1 has a sealing head 3 and a sealing foot 5. The sealing head 3 is constructed as a hollow profile and a cavity 17 is formed by a profile back 4, an upper transverse web 15 with a roughly V-shaped construction and which in the loaded state bends in the direction of the cavity 17, a sealing web 13 sloping downwards from the upper transverse web 15, a contact web 14 and a lower transverse web 16.

The sealing web 13, the contact web 14, which slopes upwards to the sealing web 13 from the lower transverse web 16, and the upper transverse web 15 are made from a foam material 20, which is externally embraced by a damp-proof membrane 21.

The lower transverse web 16, which with a horizontal web area 26 and a vertical web area 27 serves a supporting function for the sealing head 3 and in particular for the contact web 14 and is connected by a downwardly sloping connection web area 28 to the contact web 14, are in the same way as the sealing foot 5 and a cover lip 7 made from a harder material 19.

In this embodiment the sealing foot 5 is terminally provided with a retaining lip 6, which is used for anchoring seal 2 in a slot 9 (cf. fig. 3) . The cover lip 7 which is inclined slightly in the direction of the retaining lip 6 is used for covering the slot 9 (cf. fig. 3) and prevents dirt and moisture penetrating in the slot 9. · \ T' A j*) « 070 175 Level with the cover lip 7 and in the area between the sealing foot 5 and profile back 4 of the sealing head 3 it is provided a tension-proof insert 8, which runs in the longitudinal direction of the seal 2 and which can e.g. be a wire, a metal strand, a textile thread, a polyester, glass fibre or cotton thread.

On its side remote from the sealing head 3, the profile back 4 has a scallop 10. In the embodiment of fig. 1 the scallop 10 is pipelike or in the form of a longitudinal channel with a roughly semicircular cross-section. The scallop 10 extends over the entire length of the wing groove seal and ensures a better engagement of the profile back 4 on a wall surface 24 of the slot 9 (cf. fig. 3), particularly in the case of corner notches and corner wraps .

The scallop 10 is formed at a distance from the upper end region of the profile back 4 and said upper end region of the profile back 4 is provided on the side remote from the upper transverse web 15 with a protuberance 11.

Fig. 1 shows that the scallop 10 has a maximum depth traax, which is roughly half the width B of the remaining profile back 4.

The width BA of the protuberance 11 can at a rough maximum be twice the width B of the remaining profile back 4.

In the embodiment according to fig. 1 the height H of the scallop 10 exceeds the height HA of the protuberance 11 and roughly complies with the ratio 1:1.5 to 2.

The wing groove seal of fig. 2 only differs from that of fig. 1 through the shaping of the scallop 10 and protuberance 11 and the reference numerals of fig. 1 are used for identical features.

The scallop 10 is cross-sectionally U-shaped, the U-legs being relatively low and the upper leg passes as upper wall of the scallop 10 into the protuberance 11. In the case of seal 2 of fig. 2 the protuberance 11 is shaped like a roughly square or rectangular protuberance on the profile back 4. Reference is made to the description relative to fig. 1 for the dimensions of the scallop 10 and protuberance 11.

In fig. 3 the wing groove seal 2 is anchored in the slot 9 of a window wing frame 23 with the sealing foot 5, and the cover lip 7 extends over the width of the slot 9 and covers the latter, sealing head 3 is in sealing engagement on a window frame 22.

The The sealing head 3 he profile back 4 and the scallop protuberance 11 formed in the upper profile back area 4 engage in a tight and stable manner on a wall surface 24 of the slot 9, the terminal protuberance 11 extending close to a horizontal shoulder 25 of the window frame 23 and engages snugly as a result of the scallop 10. The sealing action and stable engagement of the inventive wing groove seal is therefore more particularly ensured in the corner areas with the corner wraps and corner notches .
