Definitions

  • the invention relates to the production of metal casings or frames for windows and the like by means of structural shapes, for example extruded shapes, which are usually made in aluminum or aluminum alloys and usually surface-treated.
  • structural shapes for example extruded shapes, which are usually made in aluminum or aluminum alloys and usually surface-treated.
  • the ends of the structural shapes converging into a corner are cut to form a miter, that is to say an angle of 45°, and either joined by various kinds of devices of known type, or welded together.
  • Square brackets may also be provided which are designed so as to be received within channels formed by structural shapes in order to exactly center the converging, mitered structural shapes.
  • Soft sealing strips are also usually provided which are received within channels suitably provided for in the structural shapes to cooperate with fixed structural shapes of the frame of the sash.
  • An object of this invention is to provide a casing which overcomes these drawbacks.
  • a further object of the invention is a process for making a casing by means of surface treated structural shapes, especially of aluminum alloys or equivalent type, which overcomes the problems of the known processes.
  • the process may advantageously include the use of square brackets for the mutual centering of said structural shapes, said brackets being received within channels formed by said structural shapes.
  • the positioning of said angle elements may be obtained by making them solid to said square brackets.
  • the cutting of the projecting flanges is performed mostly at right angle to the structural shapes, in order to remove the external corner of the mitered end (at 45°).
  • a flexible sealing strip may be provided along the outer perimeter of the angle element; said strip is advantageously prolonged beyond said element for its insertion within the strip-receiving channel of the structural shapes converging into the corner.
  • the angle element may be so shaped and/or formed with suitable material, so as to result elastically yielding.
  • a further object of the invention is a casing formed with structural shapes, wherein the structural shapes converging into a corner, or into each of a plurality of corners, are chamfered at their outer ends, and said casing comprising an angle element disposed within the space formed by the chamfers and which completes the rounded profile of the corner.
  • the casing may comprise section-centering square brackets which are received within the channels of the said structural shapes; in this case, the said angle element is advantageously made solid to said centering square bracket and the latter is able to position said angle element when it is engaged into the channels of the converging structural shapes.
  • the square bracket with the angle element may be made of metal and provided with a sealing strip.
  • the end cuts of the structural shapes may be orthogonal to the said structural shapes.
  • Still another object of the invention is an angle element having convex profile, suitable to be used in the above mentioned process, for forming a rounded off corner in a casing made up of metal structural shapes.
  • Such angle element may be solid to a square bracket which is used for the centering of mitered structural shapes converging into a corner, the external flanges of said structural shapes being cut off.
  • two metal structural shapes 1 of a type known per se which in particular are provided with an outer flange 1A intended to form the protruding external profile of the casing.
  • the structural shade forms a channel 1B in the flange 1A for receiving a relatively soft sealing strip 3.
  • a second channel 1C is formed sideways and internally to the channel 1B in correspondence of the flange 1A, for the purposes to be indicated hereinafter.
  • the two channels 1B and 1C are provided with undercuts allowing the use of elements to be received therein.
  • the structural shapes 1 are usually mitered, that is to say cut at an angle of 45° as indicated by 1E in the drawing.
  • the mitered cut forms very sharp angles of 45°, in the end part of the outwardly projecting flange 1A which, in turn, determine the formation of very sharp and dangerous edged at the corners of the formed casing.
  • the elimination of said dangerous edges is the object of the present invention.
  • each of the two structural shapes 1 converging at a corner to be chamfered, and which are mitered in 1E, is transversely cut at 1F, to remove the angular end of the flange 1A; the cuts 1F extend mostly in the region of the two channels 1B and 1C of each structural shape 1.
  • the removal of the angular ends of the flanges 1A by means of the cut 1F determines, when the two structural shapes 1 are joined together, the formation of a space in correspondence of the angle formed by the miter. In this space there is inserted an angle element 7 which has an outer rounded off profile 7A and a thickness corresponding to that of the flange 1A, whose end has been removed.
  • the angle element 7 is solid to the angled part of the square bracket 5 from which the two flanges 5A are made to project beyond the angle element 7.
  • the angle element 7 may be made of the same material as the square bracket 5, that is to say a synthetic, relatively rigid moulded material, or it may be applied to the square bracket 5, 5A, or it may be formed with known techniques to achieve a difference between the physical characteristics of the angle element 7 and those of the square bracket 5, in order to have the element 7 at least slightly softer than the rigid material which forms the square bracket 5.
  • the two components 5 and 7 may also be assembled after their respective formation.
  • the two structural shapes 1 are joined by clamps of a commercially known type and connected one to the other by screw means or by calking or other, or are directly welded.
  • a properly defined position of the two structural shapes is achieved through the square bracket 5, 5A which is inserted into the two converging channels 1C of the two converging structural shapes 1.
  • the same square bracket 5, 5A, which is provided with the angle element 7, places the latter in correspondence of the space defined by the cuts 1F, so that said angle element 7 takes up the space defined by the two cuts 1F and forms the corner of the casing with the convex profile 7A.
  • the latter is not provided with the sharp corner, which is typical of the known casings and which is responsible for the injury suffered from those who inadvertantly hit such corner.
  • the rounding-off 7A of the angle element 7 there is obtained a finishing of the casing which overcomes these drawbacks of the known casings.
  • the angle element 7 provides also a particularly good-looking appearance for the said casing.
  • the angle element 7 defines a channel-shaped seat along the convex profile 7A, between the rounded-off edge of the profile 7A and the projection formed by the square bracket 5, 5A.
  • a sealing strip 9 may be received.
  • Said strip 9 projects with its two ends 9A from the seat and can be housed in the adjacent channels of the two structural shapes 1, the sealing strip 3 being shorter, that is to say placed behind the edge formed by the transversal cut 1F, as indicated in 3A.
  • the end 9B of the sealing strip 9 carried by the angle element 7 is received within the channel 1B and forms an extension of the sealing strip 3.
  • a sealing strip is made to develop throughout the perimeter of the corner region of the casing.
  • the sealing strip 9, 9A may be formed together with the piece 7 or sealed thereto to provide the desired physical characteristics.
  • the sealing strip 9,9A,9A is omitted and, in the inner part of the angle element 7 a cavity 7B is formed wherein a spongy shim may be glued; this shim is able to substantially complete the sealing in the length between the two sealing strips 3 of the casing.
