Definitions
- This invention relates to a joint for connecting two mutually converging linear elements together angularly in the direction of their length, in particular converging section elements of a door or window frame.
- Joints of the kind disclosed in the present application an known, for example, from documents DE-A-3 401 106, GB-A-1 585 718, FR-A-2 550 577.
- the object of the present invention is to obviate the aforesaid drawback by providing a joint comprising a thermally insulating element to interrupt the thermal bridge between the lateral surfaces of the joint.
- the joint of the invention is of the type used for angularly connecting two linear elements together in the direction of their length, and in particular two converging section elements of the frame 2 of a door or window, for example a window 3.
- the convergence is of 90°.
- the joint 1 comprises a central element 4 and two male portions 7 and 8.
- the central element 4 is substantially a parallelepiped and therefore has all its opposing surfaces parallel.
- Said surfaces consist of two contact surfaces 5 and 6, two surfaces 14 and 15 opposite the contact surfaces 5 and 6, and two lateral surfaces 16 and 17.
- the respective male portions 7 and 8 extend perpendicularly from the contact surfaces 5 and 6. Said contact surfaces converge at a corner 9, defined as the inner corner, and are arranged to make contact with respective cross-sections 10 and 11 of section elements 12 and 13 perpendicular to the axes 25 and 26 of said section elements.
- the surfaces 14 and 15 converge at a corner 18, defined as the outer corner and rounded to satisfy both accident prevention and appearance requirements.
- the lateral surfaces 14-17 of the central element 4 are coplanar with the outer surfaces of the section elements 12 and 13.
- the male portions 7 and 8 which in the illustrated example are of parallelepiped shape, penetrate into the cavities which open at the cross-sections 10 and 11 of the section elements 12 and 13 so that the outer surfaces of the male portions 7 and 8 make contact with the inner surfaces of the cavity.
- the male portions 7 and 8 are fixed by a fixing means chosen from glue, pins, screws, welding, rivets and forced insertion.
- the joint 1A is provided with a thermally insulating element 22 to interrupt, when in operation, the thermal bridge between the lateral surfaces 16A and 17A of the central element 4A and that between the corresponding lateral surfaces 20A and 21A of the relative male portions 7A and 8A.
- the thermally insulating element 22 is positioned parallel to the plane of symmetry of the joint 1A and preferably coplanar with said plane. In this manner the two metal elements into which the joint is divided by the thermally insulating element 22 (which is a thermal insulant and hence not of metal) can in certain cases be made identical, with consequent reduction in the overall constructional cost of the joint.
- Various fixing means can be used to fix together the three component elements of the joint 1A. These can for example be chosen from those suggested for fixing the male portions 7, 8 and 7A, 8A to the relative section elements 12, 13 and 12A, 13A.
- section elements 12A and 13A also have to be provided with thermally insulating elements 23 and 24.

Abstract
Description
- This invention relates to a joint for connecting two mutually converging linear elements together angularly in the direction of their length, in particular converging section elements of a door or window frame.
- Joints of the kind disclosed in the present application an known, for example, from documents DE-A-3 401 106, GB-A-1 585 718, FR-A-2 550 577.
- Two converging section elements of a door or window frame are currently joined together by various joining elements, all of which operate in such a manner as to maintain the section elements joined together along incident surfaces usually at 45°.
- These joining methods are problematic for various reasons well known to the expert of the art. In particular, no thermal insulation is provided between the external surfaces of the joint.
- The object of the present invention is to obviate the aforesaid drawback by providing a joint comprising a thermally insulating element to interrupt the thermal bridge between the lateral surfaces of the joint.
- The invention is illustrated by way of non-limiting example in the figures of the accompanying drawings.
- Figure 1 is a perspective view of a first embodiment of the joint during the joining of the end portions of two incident section elements;
- Figure 2 is a schematic side elevation of a window frame comprising the joints of Figure 1;
- Figure 3 is a perspective view of a second embodiment of the joint during the joining of the end portions of two incident section elements; in this the joint elements corresponding to those shown in Figures 1 and 2 are indicated by the same reference numeral plus the letter "A".
- With particular reference to Figure 1, the joint of the invention, indicated overall by 1, is of the type used for angularly connecting two linear elements together in the direction of their length, and in particular two converging section elements of the frame 2 of a door or window, for example a
window 3. In the illustrated example, which is the most common, the convergence is of 90°. - Other convergence angles for forming frames and hence windows or doors of shape other than square or rectangular are however not excluded.
- The
joint 1 comprises a central element 4 and twomale portions - Said surfaces consist of two
contact surfaces 5 and 6, twosurfaces contact surfaces 5 and 6, and twolateral surfaces - The respective
male portions contact surfaces 5 and 6. Said contact surfaces converge at acorner 9, defined as the inner corner, and are arranged to make contact withrespective cross-sections section elements axes 25 and 26 of said section elements. - The
surfaces corner 18, defined as the outer corner and rounded to satisfy both accident prevention and appearance requirements. - Again for accident prevention and appearance requirements the lateral surfaces 14-17 of the central element 4 are coplanar with the outer surfaces of the
section elements - The
male portions cross-sections section elements male portions - The
male portions - According to the invention (see Fig. 3) the
joint 1A is provided with a thermallyinsulating element 22 to interrupt, when in operation, the thermal bridge between thelateral surfaces lateral surfaces element 22 is positioned parallel to the plane of symmetry of thejoint 1A and preferably coplanar with said plane. In this manner the two metal elements into which the joint is divided by the thermally insulating element 22 (which is a thermal insulant and hence not of metal) can in certain cases be made identical, with consequent reduction in the overall constructional cost of the joint. - Various fixing means can be used to fix together the three component elements of the
joint 1A. These can for example be chosen from those suggested for fixing themale portions relative section elements - In order not to undermine the insulating action of the
joint 1A thesection elements insulating elements
