FRAME SYSTEM FOR STEELWORK

Abstract

 Frame system for metal joinery, designed to replace any type of window by others, preferably in aluminium, without the need for masonry work and retaining the existing frame, with the additional option of placing a preliminary frame in the course of new building work in order to place the invention, characterized by the fact that basic sections (1 and 3) are fixed to the frame placed during building work and attached to each other by means of a spring catch (2), itself fixed onto basic section (1) while the outside basic section (3) on the other hand is anchored to the spring catch by means of its notching (4).

Description

[0001] The present description refers, as its title indicates, to a frame system for metal joinery, designed to replace all types of windows by others, preferably in aluminium, without the need to remove the window frames of wood or other types of material, with the additional option of placing a preliminary frame in the course of new building work in order to place the invention later.

[0002] At the present time, for the replacement of joinery work in wood or other material by items manufactured in extruded aluminium, it is necessary to remove the frames inserted during the construction of the building, in order to plaster in a new frame, thus requiring the hiring of the services of a plasterer.

[0003] In view of the need to resort to a plasterer, or in any case to have to undertake work on the masonry, the replacement of deteriorated windows by other more innovative models is often discarded because, over an above the problems posed by having to remove the embedded frames, the financial aspect must also be considered as this operation is far from cheap.

[0004] In order to resolve these problems the present invention has been designed comprising two basic sections, between the wings of which the frame of wood or any other material is anchored, with the positioning between the two sections being assured by means of a spring catch, which allows the insertion of one section into the other until a sufficient amount of pressure is achieved against the wooden frame, but without any possibility of it loosening. The airtightness between the inserted section and the pre-existing frame and the jamb is achieved by means of the corresponding elastic sections. Optionally, the basic interior section could incorporate the frame attaching to the corresponding window.

[0005] The present invention to replace wooden or other types of window by aluminium windows shows many advantages over the system of removing the embedded window frames as with a simple system of metal sections attached to a frame it is possible to avoid replacement, thus evidently reducing the final cost of the building work as, in addition to the elimination of the need for a plasterer, it also avoids the need to do any work on the masonry, with the additional advantage of saving time since it is not necessary to wait for materials to set or dry, installation is instantaneous and there is no need to redo paintwork.

[0006] In order to understand the object of the present invention better, the attached plan has been drawn up to illustrate a preferred practical implementation of the same. In the said plan:

[0007] The frame system for metal joinery work referred to in the present invention, as can be seen in the figures mentioned above, incorporates a basic interior section (1), which is associated with the spring catch (2) in such a way that, when the outside basic section (3) is inserted the three sections are anchored by means of the notching (4) without any possibility of coming loose unless the screw (5) is unscrewed so as to release the flange (6) of the spring catch (2). Once the basic sections (1) and (3) have been fixed to the frame, the airtightness or sealing of the jamb (7) against the frame (8) is achieved through the contribution of the decorative section (9) and the sealing section (10), both inserted in the end of the outside basic section (3), whereas the sealing of the inside basic section (1) is achieved through the sealing section (11), following the final placement of the sealing section (12) between the basic sections (1) and (3). In order to assure the alignment between the faces of the basic sections (1) and (3), a fixing bracket (13) has been placed inside the mitred angles with an adjustment so that it prevents any misalignment, just as another fixing bracket (14) has been placed on the outside of the frame in order to align the outside faces. In addition, towards the inside of the frame an anchor bracket (15) has also been planned in each angle, held in place by means of the countersunk screw (16).

[0008] The basic inside section (1) with laminated sides comprises a horizontal wing on the right end of which there is a lip pointing inwards, containing a channel (17) in a half dovetail shape in which the sealing section (11) is housed, contributing with the inner wall (18) of this channel (17) together with the lip (19) to the formation of a hole inside which the fixing bracket (13) is inserted. From the left end of the horizontal wing there is a vertical downward wing with the top half (20) offset inwards, with a horizontal lip (21) provided towards the upper and inside tip of the said upper half (20), from which lip a vertical wall (22) descends approximately halfway until it reaches the height of the offset or approximate midpoint of the vertical wing in order to provide between the said vertical wall (22) and its opposite wing, also vertical, a relatively deep channel (23) in which the notching (4) belonging to outside basic section (3) will be housed. From the vertical wall (22) and towards its upper end, there emerges a small horizontal lip (24) from which descends a small, also vertical, wall (25) separated in such a way from its opposite wall (22) that there is a channel (26), at the same time as an angled overhang (27) is created in the external angle formed by the aforesaid lip (24) and the aforesaid wall (25). To improve the introduction of the notching (4) into the channel (23), it is planned to provide an extension (28) of the upper half (20) with a flared tip (29). The vertical wing of the basic section (1) to which we are referring has at the end of its lower half (30) an inner channelling (31) in the form of a vertically arranged half-dovetail inside which the sealing section (12) is located. The appropriate anchorage points will be determined on the front faces (32), depending on the type of window chosen in each case, with the option of locating the extruded window frame in this area.

[0009] The outside basic section (3) of a laminated construction similar to basic section (1) comprises a vertical wing on the upper end of which the notching (4) is located whereas on the end of its horizontal wing another channelling (33) is located vertically in the shape of a semi-dovetail, inside which the decorative section (9) is housed, with a small channelling (36) having been left between the vertical wall (34) of the channelling (33) and the wall (35) in order to house the sealing section (10), at the same time as the aforesaid wall (35) together with the opposite lug (37) define another channelling (38) in the shape of a semi-dovetail, in this case to house the alignment bracket (14). The inside angle between the wings of the basic section (3) to which we are referring contains a chamber (39) defined between the horizontal (40) and vertical (41) walls, with the anchoring fixing bracket (15) located inside the aforesaid chamber (39) and held in place by several countersunk screws (16).

[0010] The multiple spring catches (2) arranged at intervals along the inside basic section (1) and on its vertical wall (22) have a narrow semi-rectangular cross-section on the upper end of which there is a channel (42) defined between the walls (43 and 44) which is slightly thicker and higher than the previous one and containing towards the inside a lip which is anchored in place on the angled overhang (27) belonging to the basic section (1). The lower end of the spring catch (2) that we are describing contains a flange (6) which overhangs the general thickness in order to meet up with the notching (4) of the basic section (3) for which it provides anchorage, thus also ensuring the fixation of the spring catch (2) to the basic section (1) by means of the wall (43) inserted into the channel (26).

[0011] For the hypothetical case of having to dismantle the window and therefore the frame being described, the spring catch (2) has been designed with a screw (5) on its inside, inserted in such a way that its head is opposite the vertical wall (22) of the basic section (1) at the same time as the end of its head is housed without sticking out from its neighbouring drill hole (45), while the upper end (20) of the vertical wing also has a small drill hole (46), logically located opposite, with the task of acting as a guide for access by the appropriate key to reach the screw (5) in order to turn the same leftwards and provide for the separation of the flange (6) outwards and therefore the release of the spring catch so as to recover partly or in its entirety the material used in the device.

[0012] Depending on the dimensions of the frame to which the present invention is attached, it has been planned to include on the outside basic section (3) the supplementary section (47) inside its channelling (36) in order to provide variable adaptation of this supplement to the sealing section (11).

[0013] Optionally, the inside basic section (1) may be defined in two halves, in other words the horizontal wing (48) and vertical wing (49), between which the insulating section (50) is inserted, with two opposing channels (51) having been planned on both the left end of the horizontal wing (48) and the upper end of the vertical wing (49) in a semi-dovetail shape, into which the aforesaid insulating section (50) will be anchored, with its more or less rectangular cross-section running parallel to the upper and lower bases as well as its outside and inside edges, in which a perpendicular rib (52) of a medium height has been inserted towards the centre at the same time as four small overhangs (53) have been defined in the four angles formed between the bases and the side pieces in order to be inserted into the above-mentioned channels (51) as a retention system.

[0014] The decorative section (9) of flexible material contains a fixing base (54) with an inverted T-shaped cross-section which is housed in the channel (33) corresponding to the basic section (3). The seating base (55) has a considerably greater width than the fixing base (54), with its width gradually reducing radially in a first section before its sides continue in a gradually converging straight line, with a maximum height finally capped radially. Optionally, the height can be reduced at the same time as its central core is cut out in a triangular shape (56).

[0015] The sealing section (10) comprises a cylindrical tube of flexible material (57) containing an appendix (58) with a larger radial finish.

[0016] The sealing section (11) also based on a cylindrical tube (59) contains an appendix (60) shaped as an inverted T. The sealing section (12) comprises a quarter arc (61) from the lower end of which an appendix (62) descends in the shape of an inverted T.

[0017] Having sufficiently described the nature of the present invention, as well as the manner of implementing the same, it only remains for us to add that it is possible to introduce changes of shape, material, arrangement in the invention as a whole or in the parts comprising the same, providing that such alterations do not substantially vary the nature of the invention claimed below.
