Description

"II'DTDT m pi irmVn ;ΐρη,?"ΐ,? o'^n D'^'DTTQ ηηιοο11 "HOLLOW FRAME PROFILE FOR DOORS, WINDOWS AND GLASS WALLS" The present invention relates to a hollow frame profile for doors, windows and glass walls, the profile being of rectangular cross-section and having two identical longitudinal grooves formed in it on each of two opposite sides, symmetrically to the two longitudinal median planes.

In known hollow profiles of thistype, the grooves serve for the insertion of support strips for glass and other securing or abutment elements.

Accordingto the present invention, there is provided a hollow frame profile of rectangular cross-section for doors, windows and glass walls, having two identical longitudinal grooves formed in each of two opposite sides, symmetrically to the two longitudinal median planes, the outer sides of the four grooves being formed by the inner wall of in each case one hollow web, the outer wall of i c; which is formed by the adjacent transverse wall of the hollow frame profile. By this means, it is possible to secure together, without securing elements, two or more profiles which are offset relatively to each other in the direction of both planes of symmetry, this being done by engaging a hollow web of one of the profiles with a groove in the other profile. In this manner sashes, transoms, cross-bars, side parts, skylight windows and glass walls can be equipped with identical frame profiles. In order to 2 increase the versatility of the profile, it is expedient that the groove sides should merge, by means of a convexity. 2 - EJ into the groove base which, advantageously, is externally concave. With appropriate dimensioning of the grooves, it is possible to push glass panels edged with rubber into the grooves. It is also possible to insert in the grooves lattice bars, grasping bars, sliding sashes, panels, fittings mad e of metal, plastics, timber, "sternit" and the like.

Advantageously, the sides of the grooves merge, with a viidened portion, into the base of the groove. In this case, one of the two profile walls which is not formed with grooves may (including the wall parts extending as far as the widened portion of the two adjacent grooves) consist of a separate C-profile adapted to be rigidly connected with the main profile by inserting and securing connecting elements at the abutment points.

By this means, it becomes possible to provide for the retaining and securing of the connecting elements at the abutment points of the frames before the insertion of the C-profiles and, correspondingly, to insert and tightly fix the connecting elements.

For a better understanding of the invention and to show how the same may be carried into effect, reference will now be made by way of example to four emdodiments shown in the accompanying drawings, in which: - Figure 1 shows in cross-section six of a first emdo'diment of frame profile assembled together, second η Figure 2 is a cross-section of a ^eeeea embodiment of frame profile, Figure 3 is a cross-section of part of a third mbodim nt of frame rofile and Tne combination shown only in Figure 1 and comprising six identical hollow frame profiles A, B, C, D, E and F rola es^to a wall intersection. The relevant features will be described in »reater detail hereinbelow with reference to the profile A, The hollow profile A is rectangular in cross-section.

Arranged symmetrically to the two planes of symmetry I-I and II-II, on each of the two opposite longitudinal sides, are two identical longitudinal grooves 1. The groove sides 2 merge, by means of a concave recess 3 in each case, into the groove base which is curved so as to bo concave outwardly, with respect to the profile.

The outer sides of the four grooves 1 are each formed by the inner wall of a hollow web 5 the outer wa.l 1 of which is formed by the adjacent profile wall.

The width bj_ of the hollow webs 5 forming the outer sides of the four grooves is smaller than the groove width b2<. Thus, the profiles B and D which are adjacent the profil; A and "which are correspondingly offset relatively to the profile A in the direction of both planes of symmetry I-I and II-II, can be coupled together without supplementary securing elements, the hollow web 5 of the profile A engaging in the adjacent groove 1 of the profile B or D. For this purpose, therefore it is sufficient that the width b-j- of the hollow webs 5 does not exceed the groove width b2.

The hollow profile C is coupled with the profiles B and D similarly to the profile A so that the four profiles are coupled together cross-wise without securing elements. .6.70 At the same time, the outer grooves are left free and can be used for the securing of various structural elements ,. as indicated for example in the drawing. In this connection) a glass pane 6 is shown inserted in one of the gree grooves of the profile C and is secured by means of reailiently yielding supports 7 engaging in the concave recesses 3.

The hollow webs 5, each of which forms an invardly-open groove, have the advantage that they are suitable for retaining connecting elements which can be used to connect, for example, $ o hollow profiles A in longitudinal direction by being inserted slidingly into the ends of the adjacent profiles. The said connection elements then expediently have asymmetrical T-shaped cross-section, the web of which extends into and between two hollar webs 5 positioned opposite each other, while the leg lies against the spine 13 of the associated groove 1 and is secured by snapping-in or by means of rivets or screws inserted from the groove through apertures in the spine 13.

The T-section of the composite members may alternatively be formed by two abutting angle sections* The profiles E and F are hingeably connected to the profiles B and D, respectively. Each is hinged by a door hinge plate 8, the plate 8 being provided with projections each of which is secured in a groove formed in each of the respective profiles B and E, or D and F. The appropriate grooves may serve additionally for the securing of resiliently yielding fittings 9 associated with the profiles B and D, co-operating with similar fittings 10 inserted in the free groove of the Fitted in the door frame profile E is furthermore a barrel or cylindrical lock 11 , the cylinder 12 of which is inserted between the spines 13 positioned opposite each other of the grooves 1 , whereas the lock case is inserted in the inwardly-open central grooves of the profile E.

Referring now to the embodiment according to Figure 2 j a hollow profile of rectangular cross-section having a longitudinal plane of symmetry I~I and consisting of two profile parts 21 and 22 securely connected together. Formed in the two longitudinal sides located opposite each other symmetrically to the plane I-I, are in each case two identical longitudinal grooves 23 and 24. The groove sides 2 and 26 respectively, merge through a widened portion 27 , into the throat-shaped groove base 28. The outer sides of the four grooves 23 and 24 are formed by the inner wall 29 and 3o, respectively, of in each case a hollow web 31 and 32 , respectively, the outer wall of which is formed by the adjacent profile transverse wall 33 and 34 which is free from grooves.

The transverse wall 34 , including the wall portions extending as far as the widened portion 27 of the two adjacent grooves 24 , comprisee the generally C-section profile part 22 which is adapted to be rigidly connected with the main profile part 21 , by inserting and securing a connecting element 35 at an abutment point. The free edge portions of the C-section profile part 22 overlap the correcponding free edge portion 36 of the main profile part 21 on the inside, forming the constriction of the t ut r roove end art The ends of the free edge parts 36 and free ends of the C-profile are so bevelled in the same direction and overlap each other, through the agency of their longer sides which face each other to such a slight extent that the two profile parts 21 , 22 are adapted to be snapped in resiliently with temporary deflection.

The transverse wall 34 is provided on the inside with two longitudinal strips 37 which project to such an extent that, when the transverse wall is in the inserted position, they bear at least approximately against the edge parts 36 , Disposed between the said longitudinal strips 37 is the web of the connecting part 35 having two inwardly projecting flanges 3<3. The latter and the web bear closely against the parts forming the groove base or against the edge part 36. In this manner, both the profile part 22 and also the connecting part 35 are rigidly connected with the main profile part 21 , The embodiment according to Figure 3 differs from the preceding embodiment only in the support of the groove-less transverse wall 34 and in the support of the flanges 3^ relatively to the main profile part 21.

Like reference numerals are therefore used in Figures 2 and 3 for like parts.

As can be seen from the corner portion shown i Figures 3 , the free edge part 36 of the main profile 21 is provided, as an effective extension of the bevelled portion, with a limb 0 which extends to abut against the transverse wall 34 of the C-shaped profile 22 and furthermore bears against the correspondingly bevelled longitudinal strip 37.

On the opposite side of the limb 0 , the appropriate end of the web of the connecting element abuts, whereas the corresponding flange 3^ thereof bears, at the free end, against a limb 1 of the main profile part 21 . The limb 41 consists of a prolongation of the wall part delimiting the widened portion 27 of the groove 24 towards the profile centre. The base of this groove 24 is formed with central apertures 42 through each of which a screw 43 is inserted. The screw stem is screwed through a corresponding screwthreaded bore in the associated flange 38 , thus fixing the flange 36 which is disposed slightly spaced apart from the associated portion of the main profile part 21 forming the base of the groove 24 .

The embodiment according to Figure 4 differs from the embodiments shown in Figure 2 mainly in that the connecting element 44 extends at both ends into abutment., against the base of the groove in the hollow strips 32 . In this case the strips 37 of the transverse wall 34 are omitted. Furthermore, the base of one of the grooves 24 is formed with central apertures, as in Figure 2 .

Inserted through each aperture is the stem of a screw 45 which extends through in each case one bore in the flange 38 and one screwthreaded bore in the other groove base. By this means, the connecting element 44 is secured 8 A ii-iCi particularly described and .';.<.-erta?ned i e re of m /our said invention and in what m-inner the same
