Said invention makes it possible to develop a frame profile whose reduced clearance height does not decrease the rigidity thereof.

Description

[0001] The present invention relates to the art of construction, and in particular it relates to the fencing structures of residential and public buildings, and can be suitably used for manufacture of windows and similar structures. More particularly, the present invention relates to a frame profile for manufacture of the constructional fencing structures, as well as to a system of frame profiles and a set of swing-swivel fittings therefor.

[0002] Known is a frame profile for manufacture of the constructional fencing structures, including windows and similar structures; comprising a profile body having at least one protruding portion configured as a extension. For assembling the openable window units, the profile body has a groove that accommodates devices (fittings), hereinafter termed as the fitting groove (cf., e.g. "Reference book for measuring. Methodological guide for making measurements of the window and door units", A. Yu. Bezroukov, V.L. Mikov, ed. by A.Yu. Kurenkova, NIUPTs "Mezhreghional,nyi Institut Okna", 2005, pp. 183-185; and "Design of modern window systems of civil buildings", I.V. Boriskiena, A.A. Plotnikov, A.V. Zakharov, Publishers of Association of Construction High Schools, Moscow, 2003, pp. 40-45).

[0003] Said references also teach a system of frame profiles used for assembling the units for manufacture of the constructional fencing structures, including windows or similar structures, which system includes: at least two frame profiles that comprise a profile body having at least one protruding portion configured as an extension, and a fitting groove.

[0004] But such frame profiles, and the systems implemented using them have not sufficient rigidity due to the circumstance that the fitting groove is disposed within the profile body, and consequently due to its reduced dimensions, height in particular.

[0005] Also known is a set of swing-swivel fittings usable for manufacture of the constructional fencing structures, including windows and similar structures, for the above-mentioned frame profiles; which set comprises: a main drive that transforms rotating motion of the window handle into translational motion of the locking elements; locking elements that interact with the conforming parts, angular transmissions that angularly transmit movement of the locking elements; upper and lower hinge groups that disengage frame profiles of a window unit (cf., e.g. the above-recited "Design...", pp. 170 -175).

[0006] But these practically used sets of swing-swivel fittings cannot be accommodated by the fitting groove arranged in the window profile extension.

[0007] The technical problem to be solved by the invention consists in provision of a frame profile having a lesser height, its rigidity being not compromised.

[0008] Reduced dimensions, height in particular, results in an increase in the relative surface area of glazing of a window structure assembled with the use of such frame profiles. The reduced dimensions and cross-section area also result, inter alia, result in a reduced quantity of a material required for manufacture of such frame profile, and, consequently, allows lower the cost of both a frame profile and a window structure or a similar structure as a whole.

[0009] Said object is attained by provision of a frame profile for manufacture of the constructional fencing structures, including windows or similar structures, and comprising a profile body having at least one portion configured as an extension, and a fitting groove, said fitting groove being implemented within the extension.

[0010] The inner side of at least one extension preferably has a groove to accommodate a seal to ensure tight junction of the profile with other members of the structure.

[0011] The profile body further may comprise a main chamber for disposing a reinforcing element of the closed cross-section therein; the chamber may be of the rectangular shape for the purpose of a more uniform distribution of a load thereon.

[0012] The extension is further provided with auxiliary chambers to improve the sound-proofing and thermal-physics properties of the profile; in which chambers arranged are stiffening ribs to improve strength of the profile.

[0013] The frame profile is preferably made of wood, plastic or aluminium.

[0014] Another embodiment of the invention is a frame profile for manufacture of the constructional fencing structures, including windows and similar structures; comprising a chamber that accommodates a reinforcing element; outer and inner ledges, and a fitting groove; a portion of the outer ledge, that is opposite to the glazing element, has a protruding portion configured as an extension; the fitting groove being implemented in the extension.

[0015] The inner side of at least one extension preferably has a groove to accommodate a seal to ensure tight junction of the profile with other members of the structure.

[0016] The profile body may further comprise a main chamber for disposing a reinforcing element of the closed cross-section therein; the chamber may be of the rectangular shape for the purpose of a more even distribution of a load thereon.

[0017] The extension is further provided with auxiliary chambers therein to improve the sound-proofing and thermal-physics properties of the profile; in which chambers arranged are stiffening ribs to improve strength of the profile.

[0018] The frame profile is preferably made of wood, plastic or aluminium.
