Description

 The present invention relates to a method of assembling aluminum profiles for the production of chassis and frame, and corresponding assembly systems and profiles.

 The technical sector of the invention is the manufacture of aluminum joinery from prefabricated profiles which are assembled together to form frames and frames receiving glazing or other closure panels.

 One of the main applications of the invention is the production of windows and / or opening bays comprising sliding frames with several leaves adaptable to all kinds of constructions, essentially in individual houses and for verandas.

 We know, in fact, different systems for assembling profiles known and produced for this, and which are chosen and cut on demand by installers who have taken the exact measurements of the opening to be fitted.

 Aluminum profiles are manufactured in standard bar length by specialized manufacturers, such as in the rolling of this material, and according to characteristics defined by range designers of several types of profiles; in such a way that the installer can find a set of profiles compatible with each other and associated with suitable assembly parts, so that by assembling them according to a known process with possibly additional materials according to the desired final product , this installer can meet the demand of the end customer. This technique and this organization have been established for a long time, but as building standards evolve, manufacturers' manufacturing capacities, and customer demand , problems related to energy saving imperatives, or simply looking for aesthetics, the various parties involved in the organization of manufacturing and installation seek to find new and original solutions responding to the specific problems posed .

Thus various patents have been filed in this area; for example, that of the company HYDRO ALUMINIO ORNAGO SPA in
ITALY filed on 18/12/1988 in France under number 2628787 and entitled "set of aluminum profiles for the production of frames such as window frames", the four basic profiles of which are intended to allow, by assembly, to produce mobile leaves whose internal and external faces are coplanar with those of the fixed frames. This same company also filed the same day a patent application on "aluminum profiles" in L, W, Z and T, whose coupling two by two by insulating bars allows to realize external and internal parts of all the building profiles necessary for window frames. We also know the patent application FR 2568930 filed on 08/10/1984 by
Mr.A. MERLIN on "an aluminum window with sliding sashes without frame with thermal and sound insulation", manufactured with a reduced number of aluminum profiles.

Finally, we can cite the German patents DE 3030008 and 3049568 filed on 08/08/1980 and 31/12/1980 by BROKELMANN ALUMINUM WERK and
REHAU PLASTIKS on "a complex bar profile for door frames, windows and the like, thermally insulating and process for its manufacture", comprising in particular a hollow aluminum profile and a plastic profile, engaged together by various means.

 It can be seen in these various requests for protection that one of the concerns, to which the present invention also relates, is to simplify and reduce the number of profiles concerned for the manufacture of frames and chassis, but this is not the case. is often not the major goal of current manufacturers which is rather, to offer attractive features of aesthetics and insulation. We can notice in all the aluminum joinery realizations that it is indeed necessary to have at least six or seven different profiles to be able, for example. mount a sliding frame and a fixed frame and even in the case of the Italian patents above, four basic ones are needed and at least one more for the fixed frames, i.e. five. However, taking into account the minimum quantities of profiles 'the same type necessary to allow an industrialist to produce these, taking into account his technical and economic imperatives, this obliges, and justifies the rest of their position. the range designers order large quantities of material and keep it in stock. In addition, due to the special shapes of these profiles, including closed or semi-open chambers with rails and grooves for questions of rigidity and resistance, stability and resistance, sealing and sliding, insulation etc the assembly of the profiles and the closing parts requires many special tools for drilling the walls without risking damaging the other walls : these guiding and / or cutting and / or stamping dies are also provided by the designers of profile ranges; these are specific in general to each designer and the tools also which strike the cost of the assemblies, and therefore of the installers. This complexity of tools and the number of profiles concerned prevents an individual from trying to make a chassis -same, and thus imposes this chain of stakeholders between the client and the manufacturer producing the profiles: this then strikes the final price and creates often difficult situations of competition by the number of intermediaries and distribution channels required.

Each of these mastering only part of the subject, and not wanting to lose their market share, certainly seeks to improve their products, but always following the same processes and principles of assembly, with many specific specialized profiles and their associated matrices.

 The present invention makes it possible to remedy the difficulties of the installers by proposing on the one hand a process, and on the other hand, profiles which are certainly similar to those existing by the functions and their own manufacture, but which by their characteristics , allow their assembly according to the process and respond to the problem posed.

 Indeed, one of the main objectives of the invention is to be able to assemble aluminum profiles to make all chassis and frames of the sliding or fixed type, without specific tools and with a limited quantity of different profiles.

This objective is achieved by a process of assembling aluminum profiles for the production of frames and frames for windows, bays or doors, which must close any given opening, characterized in that
- We manufacture by any known industrial means, such as rolling two types of aluminum profiles compatible with each other and of determined dimensions to allow the execution of the steps of the present process, in particular such that one called A comprises at least two open and opposite chambers each on one side of said profile, and the other is L-shaped, one branch of which can be shortened on request, and the other allows said profile to be assembled in one of the two possible positions open from previous profile
- we cut to the desired lengths corresponding to the dimensions of the opening that we want to equip and cut at 450 at each end a type A profile for two type L profiles,
- Assembling, by any known system associated with said positions, the two lengths of L-profile respectively to the two said chambers of those of the corresponding A-profile, and in one of the two possible positions which allows the branch, possibly shortened, to be penetrated into said chambers, and which releases one of the faces of this profile in order to be able to fix it by any known system against the walls of said opening,
- This produces a fixed frame composed of two vertical standing uprights, and two upper and lower crosspieces.

Once this fixed frame has been produced, a fixed window can then be obtained such that
- a fixed glazing is also installed in said fixed frame, which is pressed against a joint integral with the L-shaped profile outside the opening before assembling the L-shaped profile inside it,
- Then assemble said inner L-shaped profile previously equipped with an internal spacer that can be joined and pressing against said glazing.

The objective of the invention to also be able to produce windows, sliding windows and doors is achieved with the same profiles according to an assembly process such as
- We cut to the desired lengths corresponding to the interior dimensions of said fixed frame in the opening, cut to 450 at each end, of type A profiles and in such a way that once assembled to form a sliding frame, the chambers facing the outer periphery of this said frame, overlap the L-shaped profiles all around the fixed frame,
- Assembling with glazing and seals four lengths of said type A profiles, then constituting said frame composed of a lower cross carriage carrier to roll on the lower cross of said frame, an upper guide cross, a vertical upright lock and a vertical baffle, thanks to fixed angle brackets, and tightening the profiles against each other by inclined screws,
- Assemble an L-type profile to the vertical baffle upright in the other possible position which allows the overflow of its branch outside the profile of the vertical upright so that by doing the same with another sliding frame and installing these two frames thus produced on the two L-type profiles of the fixed chassis, the entire opening is closed by overlapping the two branches in the center, and the three A-type profiles of the frames on those of the L-type of said chassis .

 The result is new methods of assembling aluminum profiles for the production of chassis and frames, new profiles and corresponding assembly systems.

 Indeed, these methods and assemblies bring numerous advantages compared to current techniques and to the organization of their exploitation.

 First and foremost, instead of having six or seven different profiles for making sliding frames with their chassis, and fixed frames, the present invention makes it possible to limit this number to only two basic profiles, which greatly reduces the necessary stocks of the distributor and / or the installer.

 In addition, the methods of assembling these profiles and their actual design, allows all the necessary drilling and cutting to be carried out before the profiles are assembled together, and without the risk of damaging a wall as in the profiles. complex: so the installer only needs conventional drills, screwdrivers and hacksaws without tools, presses or special dies. This reduces its cost accordingly, and even allows individuals to carry out their installation. themselves; intermediaries, such as range designers, who provide the buffer storage currently required by installers, are not compulsory for the products according to the invention; the savings thus made, by adding those of the reduction in the number of profiles and therefore of the orders and 'basic stocks, of the elimination of specific tools and the reduction of the intermediaries, are then considerable.

 Finally, the products and methods according to the invention can be compatible in any case with all systems of seals and sealing brushes, roller rollers, water releases, locks and other known equipment, which are found. conventionally on current aluminum joinery: it is indeed possible to provide for the manufacture of the profiles, any guide grooves and / or any necessary ribs, and which are not the subject of the present invention.

 In the following description, we describe exemplary embodiments of the methods, assemblies and profiles according to the invention, but other embodiments can be envisaged within the framework thereof: the drawings, figures and descriptions have no limiting character.

 Figures 2A and 2B are sectional views of two sections according to the invention.

 Figure 3 is a cross-sectional view of a fixed window.

 Figure 4 is a cross-sectional view of a set of sliding doors.

 Figure 5 is a top sectional view of a set of closed sliding doors.

 Figure 6 is a front view of a lower angle of the movable frame.

 Figure 1 is an overall front view of an opening 7 in any wall and that we want to close for example by doors, or windows or sliding windows. In our example and our figures below, we have only shown double sliding frames but in other embodiments, there may be three, four or more, with slight modifications in the basic profiles described. in Figures 2.

The view represented here is known and is not specific to the invention, but makes it possible to locate the various elements which are discussed below. We note in particular
- A fixed frame 8 fixed by bolting or other known method against the inner walls of the opening 7 and consisting of aluminum profiles in general of identical profile all around and forming a rail, guide and closure by overlapping with the profiles of the movable frames 151 and 152. There are, for example, to give an identity to each part, the lower rail cross member 11, the upper guide cross member 10, and the vertical standing uprights 9.

 two movable frames 151 and 152 sliding and each placed on one of the parallel rails of the fixed frame 8, so that in the open position these frames slide by pressing on their lower crosspiece carrying the carriage 16, and by guiding by their upper crosspiece 17, and in the closed position their vertical uprights 18 called locks, overlap the vertical frames 9 of the chassis and the vertical uprights 19 middle called baffle overlap each other.

 Figures 2A and 2B are sectional views of two sections 1 and 2 compatible with each other and said to be basic, allowing them to be assembled together in various configurations as described below, to produce all of the frames and chassis described above, and possibly others.

 Profile 1, called type A, has at least two symmetrical open and opposite chambers 3 and 4 back to back, each on one face of the profile and whose edges 22 are identical and in the form of grooves of any known type, to receive various seals or known sealing brush holders. The shape of this profile may be conventional and preferably rectangular with two closed 29 and parallel faces constituting the sides of said chambers, and a wall 30 at least connecting them and constituting the bottom thereof.

 To improve the rigidity of this profile and reinforce it, it can include at least a third chamber 28 which can be closed, which is located between the two open chambers 3 and 4 and through which can possibly pass, depending on its use, the system for fixing said profile against a wall, said profile can then also include along at least one of its closed faces 29, a rail that can receive another profile of the same section as the branches 6 of profile 2 of type L.

 Profile 2, called type L, has a branch 5 which can be shortened on request thanks for example to a notch 31 weakening and reducing its thickness, and a branch 6 comprising two series of ribs 23 making it possible to position said profile 2 in a chambers 3 or 4 of said profile 1, compatible with the grooves 22 of these chambers to be immobilized there by any known fixing system: a position allows said branch 5 to penetrate according to FIGS. 3 and 4, possibly shortened, by breaking it at the notch 31, in one of the chambers and the other to release this entire branch 5 outside the profile according to FIG. 5.

 Said branch 5 may comprise, for example at the notch 31, a groove facing outwards from the L, of any known type, such as that shown on the edge 22 of the profile 1, for receiving, for example, in a configuration such that Figure 5, a sealing brush holder like many carpentry today having the same configuration of sliding doors.

 The assembly of the sections 1 and 2 between them can be done in any known manner such as by screwing, welding, riveting, gluing, stamping, fitting, etc ... and the ribs 23 then essentially have a positioning role. However, in a preferred embodiment, in order to make the assembly simpler, faster and in certain cases reversible for subsequent disassembly, at least two ribs 23 of the profile 1 of type A, allowing the two positions of the profile 2 of type L in the chambers of profile A, have a known shape of head 26 such as a triangle, a base of which hooks with the veil 27 flexible support, and then allows said assembly of the two profiles by hooking these heads 26 in the grooves 22 corresponding to profile A and the other ribs 232 which it is desired to be able to disassemble have a known face of rounded head 262, which can also be blocked in the corresponding groove 22 of profile 1 of type A.

 Instead of the triangle head 26, there may be a hooked lip or angle or half dovetail, or half round.

 The branch 6 of the L-shaped profile 2 has an end reinforced in the form of a rail 32 which allows the chassis to slide or slide as shown in FIG. 4. In this end, a groove 33 can be provided to receive like that 22 profile 1 of the seals or other known parts.

 In a particular embodiment, said groove 33 can be formed between the nearest rib 234 and the head of the rail 32, which would lighten and reduce the length of the branch 6.

 In another embodiment, this branch 6 can be in the form of a staircase with a break in shape between the ribs 231 and 234 and an elongation of the rib 233 which is used in couple with that 234 which would then be displaced.

 Figure 3 is a cross-sectional view of a fixed window. In this use, it is a question of closing an opening 7 by making a fixed frame: the assembly making it possible to constitute it comprises a section 1 of type A fixed against the walls of said opening 7 by any known means 24 passing through its solid faces 29, and two sections 21 and 22 of type L positioned and immobilized each in a chamber 3 and 4 of the section 1 in the position corresponding to the penetration of their branch 5 possibly shortened therein, in such a way that their other branches 6 located at the same height above the profile 1 reconstitute a U-shaped profile therewith.

 In order to immobilize a glazing 12 in this frame and to achieve a good seal, a known seal 13 is placed in the groove 23 at the end of the branch 6 of the external profile 22 and against which the glazing 12 can be applied before the mounting of the internal profile 21. The latter receives, before its mounting, also an internal spacer which can form a seal 14 in its groove 33 and which bears on said glazing 12.

 Various holes 34 can be provided before mounting to evacuate runoff water or internal and external condensation as in any known assembly.

 For security reasons against burglaries, the outer profile 22 can be permanently fixed to the profile 1 by welding or screwing inaccessible from below or by any other means before the profile 1 is fixed in the opening 7 and only the inner profile 21 is mounted after the glazing and can be kept removable.

 Figure 4 is a cross-sectional view of a set of sliding doors installed in an opening 7, of which only the lower level, or the floor, can be seen.

 This assembly comprises a fixed frame 8 constituted like that described in FIG. 3, by a profile of type A and two profiles 21 and 22 of type L, and fixed in the opening by any means 24. In this figure it is therefore of the lower cross member 11 of the frame frame.

 On the two ends 32, then forming a rail, are placed two mobile frames 151 and 152: each side of these frames is constituted by a section 1 of type A in which one of the chambers 3 receives the glazing 12 in a known manner between two seals 13 fixed in the grooves 22 of this chamber and the other chamber 4 facing the external periphery of said frame 15 can overlap the rail of the fixed frame 8. The assembly of the sides of these frames is described in FIG. 6.

 In the lower cross member 16 of the frame 15 shown here, the chamber 4 of the profile 1 receives any sliding system of said frame on the rail 32 such as a ball trolley, or roller 25 of known type: this system has exactly a shape compatible with that of chamber 4 in which it is threaded, immobilized and adjusted.

 The lower grooves 22 of the profiles 1 of the mobile frames receive known brush holder systems 35 rubbing under the rollers 25 and on the end of the rail 32 in order to limit the entry of air and outside water.

Figure 5 is a top view in section of a set of sliding door frames in the closed position such as for example that shown from the front in Figure 1 or in cross section in Figure 4. If we call the median planes of mobile frames AA and BB, we thus find the same distance d separating them, which in fact corresponds to the distance separating the two middle upper edges of the rails 32 of the chassis 8 shown in FIG. 4. This distance reference of course conditions the dimensions of the basic profiles 1 type A and 2 type
L, as in all known specialized profiles for producing such mobile frames and supporting frames.

 To thus achieve a closure between the two movable frames, always using the same basic profiles, a vertical side 19 called a baffle of the sliding movable frame 151 located in the closed position of the opening, plumb with one side d another frame 15 located on a parallel rail, comprises in the chamber 4 of the profile 1, a profile 2 of type L positioned and assembled with this chamber in the position allowing the overflow of its branch 5 outside of the profile 1, so that by doing the same symmetrically with the profile 1 of the other frame 152, the two said branches 5 overlap, and make a baffle blocking in the closed position of said movable frames.

 In addition, if said branches 5 each have a groove therefore turned towards the outside as indicated in FIG. 2B, at the level for example of the notch 31, the brush holders of known type can be threaded therein to ensure a tightness of continuity by said brushes then rubbing against the faces 19 of the profiles 1 facing them in the closed position.

 In this assembly configuration, the ends 32 can serve both as handles to assist in the sliding maneuvers of said frames and vertical reinforcements to increase the inertia of the uprights 15 which in the closed position are not held in the fixed frames as on the other three sides and must resist the thrust of air, such as wind, on the surface of the glazing.

 Figure 6 is a front view of a lower angle of the movable frame, but in the absence of the rollers 25, this angle may also be an upper angle of the frame.

 Indeed, to hold together the four sides of said frame, consisting for example of vertical uprights 18 and horizontal crosspieces 16, as defined above, each end of these sides is cut to approximately 450 and comprises a corner bracket 20 whose branches are threaded into the chambers 4 adjacent to 900 on each of these said sides: each of these branches comprises an inclined screw 21 which by their screwing rests on the bottom 30 of said chambers, then immobilizing the profiles and tightening them one against each other.

 In another version, it can be fixed in said chambers, fixed studs then connected by bolts, or screws to said brackets and whose tightening would bring them closer to said studs, and would also tighten the profiles against each other.

 As regards more particularly the branches of said angle brackets 20 placed in the ends of the lower cross member 16 of said frame 15, they comprise any known system of sliding on rail such as the adjustable roller carrier carriages 25.
