Definitions

  • the present invention relates, in general, to a window frame equipped with easily positionable and demountable joining means, configurate for ensuring high positioning accuracy between the main frame and the glass holder frame of the window frame.
  • the invention also relates to the relative method of fabrication of the window frame.
  • said invention relates to the field of window and door frame manufacturing in general and, in particular, to the fabrication of wooden and/or composite window and door frames.
  • window and door frames with thermal insulation
  • a main frame typically made of wood or PVC, on which an outer covering of aluminum or plastic material is mounted to protect the wood from weathering, such as light, rain, and temperature changes; a layer of insulating material, such as a cork or wood fiber panel, is then embedded between the main frame and the outer covering in order to reduce heat loss between the interior and exterior environments.
  • the joining means between the wood/aluminum profiles and between the thermal insulation and the interior frame are made of of special spacers, usually made of resin, which have, on one hand, an attachment formation to the wood profile and, on the other hand, an attachment formation to the aluminum profile and/or to the thermal insulation to make the mechanical connection between the structural elements.
  • Each spacer is normally equipped with an enlarged head, which creates an undercut inferiorly for retaining the thermal insulation or wood profile, and carries mounted externally a respective clip for snap or rotational attachment of the aluminum covering.
  • a gasket can be attached to the wooden or aluminum profile, or to both, in the case of openable frames, which ensures sufficient rebate sealing of the closed window frame.
  • gaskets and/or clips are then attached to the wooden profile by screws, to which the stability of the connection is entrusted.
  • a first drawback of such structures is that fixing by screws lengthens the assembly time of the window frame and requires the use of special equipment, consequently increasing its installation costs, and is susceptible to possible errors in the positioning of spacers and clips; it also makes it necessary to use assembly jigs and screwdrivers.
  • the joining means may comprise a plurality of clips, which are arranged in increments along the structural members and connected by a snap and/or interlocking coupling with the first wood structural member and by a snap and/or interlocking coupling with the second insulation and/or aluminum structural member, respectively; since the couplings are demountable and the clips constitute the only existing means of restraint between the structural elements, the connection between the structural elements of the window frame is also of the demountable type and does not require applications of screws, nails, or other similar auxiliary means of attachment.
  • a realization of this type allows for fairly rapid and easy assembly, even by personnel who are not particularly experienced, and the absence of screws speeds up the assembly of the window frame; not least, the gasket, clips and some structural elements could also be replaced in part at a later time after installation.
  • the aim of the present invention is, therefore, to overcome the drawbacks of the prior art complained of above and, in particular, to realize a window frame with joining means having a high positioning accuracy, which is simple, fast and practical to realize and quick to assemble, which can be carried out without the use of special equipment.
  • Another aim of the present invention is to make a window frame with joining means having a high positioning accuracy, which allows it to be made in a single processing step, so as to require considerably low costs, compared with the prior art, regarding production, assembly and installation.
  • a further aim of the invention is to make a window frame with joining means having a high positioning accuracy, which is also extremely reliable over time, efficient, economical and functional, compared with the prior art.
  • the window frame may otherwise consist of a door, French window, skylight, etc., whether or not provided with one or more glass panels.
  • the window frame comprises, as in the case of traditional windows and doors, a frame, intended to be anchored recessed in a wall of a building, which usually has the shape of a quadrangular frame obtained with at least two uprights and at least two crosspieces suitable for defining a plane for laying and installation of the frame; the window or door frame has an inner side, facing the use space of the building, and an outer side, facing the environment outside the building, to perform functions of separation, protection, insulation of rooms, as well as communication and, if necessary, visual contact between the indoor and outdoor environment, as well as natural ventilation within the rooms.
  • Figure 1 attached shows a portion of a window frame, such as a door or window sash, which basically comprises two distinct elements: a main frame 10 and a glass holder frame 11.
  • the main frame 10 and the glass holder frame 11, that comprise the window frame are made from a single initial piece and are held together by a rib of material (preferably wood) at the ends of the uprights 12 and of the crosspieces 13 of each main frame 10 and of each glass holder frame 11 and, consequently, at the corner portions of the window frame.
  • a rib of material preferably wood
  • the two elements (main frame 10 and glass holder frame 11 are divided only after they are joined by the uprights 12 and crosspieces 13, composing the window frame.
  • the profiling of the main frame 10 and the glass holder frame 11 is advantageously carried out by single processing, using a first tool for profiling the inner side and a second tool for profiling the outer side.
  • the pieces that are processed are four, although the finished frame consists of eight elements in total (four in the main frame 10 and four in the glass holder frame 11).
  • a plurality of clips 14 are used to join the glass holder frame 11 (and its glass) to the main frame 10 of the window frame.
  • each clip 14 is designed to be inserted into a special slotted seat 25 of the main frame 10 in a manual manner, without the use of special equipment, so as to ensure high positioning accuracy.
  • a single working tool 26 is used, that, in the same working cycle and at different depths of the frames 10, 11, is able to perform a drilling and slotting process making a slotted seat 25 in the main frame 10 and a recess 24 on the glass holder frame 11, positioned frontally of the slotted seat 25 ( fig. 6 , 7A, 7B ).
  • each clip 14 can be housed in the slotted seat 25 of the main frame 10 and inserted, with its own end, into the recess 24 of the glass holder frame 11 ( fig. 8A, 8B , 9A, 9B ).
  • each clip 14 has a first surface or face 15 and a second surface or face 17, opposite to the face 15.
  • the surface or face 15 comprises a cylinder 16, which allows the centering of the clip 14 in the seat 25 of the main frame 10, while the face 17 has laterally parallel planes that allow the alignment of the clip 14 in a perpendicular direction within the seat 25.
  • the cylinder 16 of the face 15 has a knurled sector 18 preferably placed on the opposite side of the glass holder frame 11 (multiple knurled sectors 18 placed on the side surface of the clip 14 may also be provided).
  • the knurled sector 18 makes beat on the inside of the main frame 10, is aligned with the direction of the clip 14, and is equipped with a snap-fit 19, which is capable of realizing pressure on the clip 14 for a proper seating of the clip 14 in the slotted seat 25.
  • clip 14 has a recess 20 in the face 15 allowing proper contact between the surface of clip 14 and the painted wood of the main frame 10 of the window frame.
  • clip 14 has a plurality of lateral bevels 21 at one side opposite wherein the knurled sector 18 is provided, to facilitate the insertion of said end into the recess 24 made in the glass holder frame 11.
  • each clip 14 is ensured by the insertion of a screw 23, attached externally to the main frame 10, which is inserted into a hole drilled in the glass holder frame 11 in a direction perpendicular to the surfaces 15 and 17 of the clip 14.
  • the tip of screw 23 is apt to fit inside a seat 22 provided at the end of the clip 14 housed in recess 24 and opposite to knurled sector 18, so as to realize tightening and stability of clip 14 between frames 10, 11.
  • the fixing screws of clip 14 since they are inserted externally to the main frame 10, can be easily removed to carry out any maintenance of the window frame.
  • a further special feature of clip 14, as mentioned above, is that different clips 14 can be inserted at various depths of the main frame 10, thus allowing the pulling force to be applied in the centerline of the glass holder frame 11 even when using crosspieces 13 of significant size, as in the case of French doors.
