Abstract
Description
Title of the invention: Mechanical construction profile system comprising at least one local fastening element 1. Scope of the invention
[0001] The field of the invention is that of mechanical construction profiles used in various fields to work in the manufacture of objects.
[0002] The invention finds particular application in the field of joinery, in which mechanical construction profiles are commonly used to manufacture, for example, doors and windows with or without opening parts. 2. Prior art
[0003] Joinery elements, such as doors and windows, are traditionally manufactured using mechanical construction profiles which are assembled together to form the frames and, where applicable, the sashes.
[0004] For example, a door generally comprises a frame delimiting an opening and at least one leaf attached to the frame in a movable way to close or open this opening.
[0005] The frame generally comprises a top rail and a bottom rail, as well as two side stiles. The rails and side stiles each comprise a mechanical construction profile, the mechanical construction profiles being assembled to each other to form the frame.
[0006] According to the same principle, an opening can comprise a top rail and a bottom rail, as well as two side stiles. Each of the rails and side stiles comprises a mechanical construction profile, the mechanical construction profiles being assembled to form a frame. This frame can be filled, for example, by one or more glass and / or metal or plastic panels...
[0007] These profiles are generally manufactured by extrusion in metal or plastic. To allow the profiles to be assembled together or to attach accessories to the profiles, the profiles are equipped with screw fastening means.
[0008] These screw-fastening means include anchor points formed within the profile. As shown in [Fig. 1], which illustrates a through-section of a profile 10, these anchor points 11, or sockets, generally have an open annular cross-section and extend longitudinally along the entire length of the profile. These anchor points define an internal recess 12 whose geometry is designed to receive a screw. In the woodworking trade, this type of anchor point is called a socket.
[0009] Given that the profiles and the honeycombs are made by extrusion, the honeycombs extend all along the profiles.
[0010] However, the alveovis are only used occasionally to make the assemblies by screwing and not over their entire length.
[0011] Since the honeycomb cores are formed from a single piece of material, their manufacture requires the consumption of the raw material from which the profile is made. However, since these honeycomb cores are only used intermittently, their production along the entire length of the profile results in a consumption of raw material that is not necessary but merely imposed by the profile extrusion manufacturing process.
[0012] Thus, the technique of assembling profiles by screwing and threaded joints leads to overconsumption of raw materials. This overconsumption of materials also has a negative impact on the carbon footprint of the manufacture of joinery elements.
[0013] There is therefore a need to improve the assembly techniques of mechanical construction profiles, particularly those used for the manufacture of joinery elements. 3. Objectives of the invention
[0014] The invention aims in particular to provide an effective solution to at least some of these different problems.
[0015] In particular, according to at least one embodiment, an objective of the invention is to provide a more environmentally friendly technique for assembling mechanical construction profiles.
[0016] In particular, the invention aims, according to at least one embodiment, to provide such a technique which contributes to reducing the quantity of material entering into the manufacture of mechanical construction profiles.
[0017] Another objective of the invention is, according to at least one embodiment, to provide such a technique which contributes to reducing the carbon footprint of the construction of elements made from mechanical construction profiles, such as joinery elements.
[0018] Another objective of the invention is, according to at least one embodiment, to provide such a technique which is versatile in particular in that it allows to offer great freedom in the placement of assembly points of profiles together and / or accessories.
[0019] Another objective of the invention is, according to at least one embodiment, to provide such a technique which is simple and / or robust and / or cheap. 4. Presentation of the invention
[0020] To this end, the invention proposes a mechanically constructed profile system comprising at least: - a profile extending along a longitudinal axis, said profile comprising at least one rail extending along said longitudinal axis; - a local fixing element forming at least in part at least one fixing housing suitable for housing a screw, said at least one fixing element being suitable for cooperating with said at least one rail to be secured at point to said at least one profile.
[0021] Thus, the invention consists not in implementing alveovis all along the profile as in the prior art, but in providing the profile with one or more longitudinal rails allowing the occasional fixing of one or more local fixing elements allowing an assembly by screwing profiles together and / or accessories.
[0022] The invention thus contributes to reducing the material consumption of the profile insofar as the housing for receiving a screw is no longer formed along the entire length of the profile. Only the rail is formed along the entire length of the profile, and this rail does not in itself define, at least not entirely, the housing for receiving a screw, this housing being at least partially formed in the local fastening element.
[0023] This reduction in raw material consumption leads in turn to a decrease in carbon impact.
[0024] According to a preferred feature, said at least one local fastening element comprises a body, said body alone delimiting the contours of said at least one fastening housing.
[0025] In this case, the fixing housing suitable for receiving a screw is formed independently of the profile.
[0026] According to another preferred feature, said at least one local fastening element comprises a body, said body delimiting, with said profile, the contours of said at least one fastening housing.
[0027] In this case, the fixing housing suitable for receiving a screw is formed by the assembly of the fixing element to the profile.
[0028] According to another preferred feature, said body of said at least one local fastening element includes at least one fastening portion of complementary shape to that of said at least one rail, and capable of cooperating with said at least one rail.
[0029] This allows a local fixing element to be assembled in a simple, economical but reliable manner to a profile by means of a rail-slide type system.
[0030] According to another preferred feature, said rail comprises at least one central core, said body of said at least one local fastening element delimiting with said at least one core said at least fastening housing.
[0031] This provides good robustness and ensures good positioning of the local fixing element in the profile rail.
[0032] According to another preferred feature, said at least one fixing housing has an essentially circular cross-section, said body comprising at least a first portion of said at least one fixing housing and said at least one web comprising at least a second portion of said at least one fixing housing, said at least a first and second portions each having a center of geometry coinciding with the axis of said at least rail.
[0033] In this case, the portions of the core fixing housing on the one hand and of the local fixing element on the other hand are concentric.
[0034] According to a preferred feature, a system according to the invention includes means for holding said at least one local fastening element in said at least one rail.
[0035] This allows the position of the local fastening element to be maintained on the profile, thus optimizing the assembly of profiles and / or accessories. In particular, this can facilitate assembly by an operator since, once the local fastening elements are in place, they no longer need to worry about their positioning as they are held securely there.
[0036] In this case, the coefficient of friction between said at least one rail and said at least one fastening element is preferably chosen such that said retaining means ensure the retention in position of said at least one local fastening element in said at least one rail by friction.
[0037] Playing on the coefficient of friction between the rail and the fixing element to maintain the local fixing element in position relative to the profile is a simple, economical but nevertheless effective way of ensuring this function.
[0038] According to a preferred feature, said means for holding said at least one local fastening element in said at least one rail comprise notching elements provided on said at least one rail and / or said at least one fastening element to ensure said holding.
[0039] Such notches make it possible to fulfill the function of the means of holding in position simply and efficiently.
[0040] According to a preferred feature, said means for holding said at least one local fixing element in said at least one rail comprise adhesive elements provided on said at least rail and / or said at least one fixing element to ensure said holding.
[0041] Such adhesive elements make it possible to fulfill the function of the means of holding in position simply and effectively.
[0042] According to a preferred feature, said means for holding said at least one local fastening element in said at least one rail are configured so that a screw screwed inside said at least one fastening housing acts by crushing material on said at least one local fastening element and on said at least one rail to block in translation said at least one fastening element relative to said at least one rail along the longitudinal axis of the latter.
[0043] This provides good robustness and ensures good positioning of the local fixing element in the profile rail by means of a screw screwed into the fixing housing, the threads of the screw engaging both with the core of the profile rail and with the local fixing element.
[0044] According to a preferred feature, said at least one fixing housing has an essentially circular cross-section, said body comprising at least a first portion of said at least one fixing housing and said at least one core comprising at least a second portion of said at least one fixing housing, said at least one first and second portions each having a center of geometry, the centers of geometry of said at least one first and second portions of said at least one fixing housing extending respectively along two axes distant from each other and parallel to the longitudinal axis of said at least one rail, said screw screwed into said at least one housing acting on said at least one rail and said at least one local fixing element to move said at least one fixing element relative to said at least one rail and thus lock it in position by pressing said at least one fixing element against said at least one rail..
[0045] In this case, the housing portions of said core on the one hand and of said local fixing element on the other hand are concentric.
[0046] This embodiment ensures that a local fastening element is held in position by means of the interaction between the screw thread and the rail and the body of the local fastening element, and by applying pressure to the local fastening element against the profile. This provides a simple and effective way to reinforce the positioning of a local fastening element relative to the profile.
[0047] According to a preferred feature, said at least one local fastening element comprises a body, said body comprising two half-bodies joined to form said body.
[0048] This embodiment makes it possible to perform the function of a prior art alveovis in a footprint substantially as compact as that of the prior art. This also facilitates the manufacture of a local fixation element, which can in particular be obtained by a molding process.
[0049] According to a preferred feature, said at least one rail comprises a female portion complementary to a male portion of said at least local fastening element, or vice versa.
[0050] According to a preferred feature, said local fastening element comprises a stamped sheet metal body.
[0051] Stamping makes it possible to manufacture local fastening elements economically, especially compared to the use of extrusion techniques (in particular micro-extrusion of aluminum alloy parts), pultrusion, profiling, rolling, bending, injection, electro-erosion or machining.
[0052] According to one possible feature, said body comprises at least two fastening elements capable of cooperating respectively with a rail of said profile.
[0053] According to a preferred characteristic, said at least two fastening elements are provided on at least two opposite edges of said body.
[0054] In this case, said at least one fixing housing is preferably formed by wings cut out and deployed alternately on either side of a median plane passing through said at least two opposite edges.
[0055] As explained in more detail in the description, such an implementation makes it possible to shift the local fixing elements towards the center of the cavity of a profile and, where appropriate, to improve the sealing at the junction between an interface piece, a profile and a door threshold.
[0056] The invention also relates to a local fastening element for a system according to any one of the variants described above.
[0057] The invention also relates to a joinery element comprising at least one profile system according to any one of the variants set out above.
[0058] A joinery element according to the invention preferably belongs to the group comprising: - the doors; - windows with or without opening(s); - the gates; - the fences: - roller shutters; - blinds; - the pergolas; - verandas. 5. Description of the figures

[0072] 6. Description of particular embodiments
[0073] Various examples of the realization of a mechanical construction profile system according to the invention are presented in relation to figures 2 to 21.
[0074] In general, a mechanical construction profile system according to the invention comprises at least: - a 20 profile; - a local fixing element 21 forming a fixing housing 22 suitable for housing a screw.
[0075] The profile 20 extends along a longitudinal axis. It is preferably produced by extrusion or pultrusion. Alternatively, it could be produced by profiling, rolling, bending, injection molding, electrical discharge machining, or machining. It is also preferably made of metallic material, in particular aluminum alloy or steel. or in thermoplastic material such as pvc, polyamide, abs or thermosetting such as glass-polyester or carbon-epoxy composite.
[0076] The profile 20 includes at least one rail 23. This rail 23 extends along the longitudinal axis and all along the profile 20. It is made in the mass of the profile so that it forms with it only one piece.
[0077] The local fastening element 21 is adapted to cooperate with the rail 23 to be attached at specific points to the profile 20. One or more local fastening elements 21 can be attached to the profile 20 at the required location(s). They can be made of plastic, in particular polyamide or other materials, or of metal, in particular aluminum alloy, steel, or other materials. They can, for example, be manufactured by spinning, roll forming, injection molding, casting, machining, sheet metal forming, or stamping.
[0078] In the embodiment illustrated in [Fig. 2], the local fastening element 21 comprises a body 24. This body 24 alone defines the contours of the fastening housing 22. In this embodiment, the housing 22 has a closed peripheral contour. It could alternatively have a longitudinal slot. The body 24 includes a male connecting portion 25 to the rail 23 having a shape complementary to the female internal shape of the rail 23 and adapted to fit inside it. Together they form a dovetail joint.
[0079] In variants, such as those illustrated in Figures 3 and 6, the rail 23 could have a male portion 230 and the local fixing element 21 could have a female joining portion 250 suitable for cooperating with the male portion 230 of the rail 23.
[0080] The system includes means for holding in position at least one local fixing element 21 in the rail 23 of the profile 20.
[0081] In this embodiment, these positioning means comprise adhesive elements provided on the rail 23 and / or the fastener 21 to ensure that the fastener 21 is held in position within the rail 23, i.e., to prevent it from sliding unintentionally within the rail. These adhesive elements comprise, for example, hot-melt adhesive cords 26 attached to the fastener 21. In this case, after the local fastener(s) 21 are positioned in the desired locations within the rail 23 of the profile 20, the local fastener(s) are heated to activate the adhesive, thereby immobilizing the fastener 21 by bonding.
[0082] Figure 4 illustrates another embodiment in which the body 24 of the local fastening element 21 alone defines the contours of the fastening housing 22. Unlike the previous embodiment, the peripheral contour of the housing The fixing part 22 is not closed but has a slot 27 at the level of its attachment portion 25 to the rail 23.
[0083] According to another approach, the body 24 of the local fixing element 21 delimits, together with the profile 20, and not alone as in the previous embodiment, the contours of the fixing housing 22. This is illustrated in particular in figures 5, 6, 7 and 8.
[0084] In these embodiments, the rail 23 comprises a central web 28. The body 24 of the local fixing element 21 delimits with the web 28 the fixing housing 22. The web 28 passes through the slot 27 of the local fixing element 21.
[0085] A mechanical construction profile system according to the invention preferably includes means for holding in position at least one local fixing element 21 in the rail 23.
[0086] In the embodiments of Figures 5 and 6, the mounting housing 22 has an essentially circular cross-section. The body 24 comprises a first portion 221 of the mounting housing 22 and the web 28 comprises a second portion 222 of the mounting housing 22, the first and second portions each having a center of geometry along coincident axes parallel to the longitudinal axis of the rail 23. The centers of geometry of the first and second portions of the mounting housing coincide in the longitudinal median plane of the rail; i.e., the first and second portions are concentric.
[0087] Thus, the local fastener 21 and the rail 23 are configured so that a screw screwed into the fastener housing 22 acts by compressing material on the local fastener 21 and on the rail 23 to block the fastener 21 against translation relative to the rail 23 along the latter's longitudinal axis. In this way, the insertion of the screw into the fastener housing 22 and its engagement in the material of the first 221 and second 222 portions of the fastener housing will coordinate the tapping of the peripheral contour of the fastener housing 22 to hold the fastener 21 and the rail 23 opposite each other and contribute to the pull-out resistance of the assembly. This configuration therefore constitutes a means of holding at least one local fastener 21 in position within the rail 23.
[0088] The means for holding in position may include adhesive elements such as those described in relation to the first embodiment, and which could be implemented in any embodiment.
[0089] The means of maintaining the position may consist of choosing the coefficient of friction between the rail 23 and the fastening element 21 so as to ensure that at least one local fastening element 21 is held in position within the rail 23 by friction. More specifically, the geometric fit between the rail 23 and the local fastening element 21 will be determined to achieve a more or less forceful hold by hand assembly, mallet assembly, or press assembly.
[0090] The means for holding in position at least one local fixing element 21 in the rail 23 may include notching elements provided on the rail 23 and / or the fixing element 21 to ensure holding in position.
[0091] In the embodiment shown in Figures 7 and 8, the means for holding at least one local fastener 21 in the rail 23 are configured so that tightening a screw inside the fastener housing 22 acts on the local fastener 21 to move it within the rail 23 and press it against the walls of the rail 23, thus locking it in position. The fastener 21 is therefore mounted to move in translation along an axis transverse to the rail 23 (see arrow in [Fig. 8]).
[0092] In this case, the mounting housing 21 has an essentially circular cross-section. The body 24 comprises a first portion 221 of the mounting housing 22, and the web 28 comprises a second portion 222 of the mounting housing 22. The first and second portions each have a center of geometry along axes parallel to the longitudinal axis of the rail and separated by a distance d (see [Fig. 7]) in the longitudinal median plane of the rail; i.e., the first and second portions are not concentric.
[0093] In this way, when a screw is screwed into the fixing housing 22, the fixing element 21 moves in translation in the rail 23 along an axis transverse to the rail so that walls of its bonding portion 25 are pressed against opposing internal walls of the rail 23. This variant also ensures a good grip of the screw on both geometries and thus prevents slippage of one relative to the other.
[0094] In this configuration, the insertion of the screw into the fixing housing 22 and its gripping in the material of the first 221 and second 222 portions of the fixing housing will coordinate by material crushing the tapping of the peripheral contour of the fixing housing 22 to help maintain the fixing element 21 and the rail 23 opposite each other and contribute to the pull-out resistance of the assembly.
[0095] In variants of the different embodiments, the rail could have a male portion and the local fastening element 21 could have a female fastening portion capable of cooperating with the male portion of the rail or vice versa.
[0096] In this regard, figures 9, 10 and 11 illustrate a variant of the embodiments of figures 7 and 8 in which the web 28 of the rail constitutes a male element capable of cooperating with a female fastening portion 250 of the local fastening element 21.
[0097] Figures 12 and 13 illustrate a variant in which the local fixing element 21 is not a single piece. On the contrary, its body 24 comprises two half-bodies 241.
[0098] In the illustrated variant, the rail 23 includes a female portion suitable for receiving a male portion of the fastening portion 25 of the local fastening element 21. Alternatively, the male portion could be located on the rail 23 and the female portion on the local fastening element 21.
[0099] The dimensions of the two half-body 241 are chosen such that when the two half-body 241 cooperate with the rail 23, they together form the fixing housing 22. Each half-body 241 includes a half-portion of joining 251 which together form the portion of joining 25.
[0100] This embodiment has the advantage of allowing the local fixing elements to be installed in a more compact manner than the previous ones.
[0101] Figures 14 to 18 illustrate another embodiment in which the local fixing element 21 is monobloc and made of stamped sheet metal.
[0102] The local fastening element 21 is made from a sheet metal which, after stamping, comprises: - two opposite edges constituting fastening elements 25 capable of cooperating respectively with a rail 23 of the profile 20; - a fixing housing 22 formed by wings 223 cut out and deployed alternately on either side of a median plane passing through the two opposite edges.
[0103] Alternatively, this local fastening element with two opposing edges constituting joining elements 25 could be obtained by means other than stamping. For example, it could be obtained by injection molding, molding, or any other suitable manufacturing technique.
[0104] Alternatively, the mounting housing 22, rather than being laterally delimited by wings 223 cut out and deployed alternately on either side of a median plane passing through the two opposite edges, could be laterally delimited by uninterrupted surfaces.
[0105] In the embodiment below, the profile comprises female rails adapted to receive male fastening elements. Alternatively, the rails could be male and the fastening elements female.
[0106] This embodiment may in particular allow: - to offset a local fixing element 21 from the edge of a profile 20; - to improve the sealing at the junction between an interface piece, a profile 20 and a door threshold.
[0107] The implementation of the technology for obtaining a prior art profile such as that illustrated in [Fig. 1] by extrusion requires that the anchor points 11 (alveovis) be placed in contact with the partitions 100 of the profile because extrusion necessitates maintaining continuity of the material during extrusion. Thus, if one wishes To position an alveovis 11 more towards the "center" of cavity 101 in a profile 10 by offsetting it downwards on [Fig. 1], it is necessary to add internal partitions (not shown), such as partition 100, more towards the center of cavity 101. This, however, is costly in terms of raw materials. Furthermore, this is not always feasible, depending on the size of the profile. Indeed, small cavities are not feasible because their production would require tooling whose strength would not be sufficient to withstand the forces resulting from the pressure of the material during extrusion.
[0108] This embodiment of Figures 14 to 18 has the advantage of overcoming this constraint, since the position of the assembly points (i.e., the rails 23) of the local fastening element 21 is determined by the geometry of the stamped local fastening element 21 and not by constraints inherent to the extrusion technology. Indeed, the rails 23 that secure the stamped local fastening element 21 can be made anywhere within the profile cavity without constraint. This embodiment therefore offers the advantage of considerable freedom in the placement of the rails 23 for assembling the local fastening elements 21, thus allowing for optimal adaptation to the need to fasten various profiles or accessories together.
[0109] Furthermore, offsetting the local fastener element towards the center of the cavity in the profile can improve the seal at a connecting piece 32 that can be interposed between a first profile 30 acting as a door threshold bar and a second profile 31 (see [Fig. 19]). Such an assembly principle is described in particular in patent document FR3055650. In such a configuration, offsetting the position of the local fastener elements 21 towards the center of the profile cavity reduces the center distance between two opposing local fastener elements and thus moves them further from the corresponding edges of the profile. Consequently, the holes for the assembly screws in the connecting piece 32 are located further from its edges. This provides more space for a sealing gasket around these holes and therefore improves the seal.
[0110] In the embodiment just described, the two opposite edges of the body each define a connecting element capable of cooperating with a rail of the profile. In variations, more than two connecting elements may be provided on the body. The connecting elements, regardless of their number, may not be located on two opposite edges of the body. They may, for example, be arranged in a essentially uniform manner around the separating element to form a star. Such an arrangement helps to stabilize the connecting element relative to the profile, thereby improving the robustness of the assembly.
[0111] The different embodiments can be combined.
[0112] A mechanical construction profile system according to the invention can, for example, be used to manufacture joinery elements, such as: - doors (entrance, window, balcony, service, interior, communication, commercial, industrial, etc.), - gates (garage, fence, etc.), - windows with or without openings (casement, sliding, roof, etc.); - fences: - roller shutters; - blinds; - the pergolas; - verandas.
[0113] Figures 22, 23 and 24 illustrate the joining of a threshold 30 (or lower rail) of door frame to a lateral jamb 31 (or profile) by means of a profile system according to the prior art comprising alveovis.
[0114] In this case, each end of the threshold 30 is secured to the lateral upright 31 by means of three screws 32 which are screwed into the sockets 33, or screwing shaft, provided all along the upright 31.
[0115] Figures 19, 20 and 21 illustrate the joining of a threshold 30 (or lower crossbar) of door frame to a lateral post 31 by means of a profile system according to the invention.
[0116] In this case, each end of the threshold 30 is secured to the side post 31 by means of three screws 32 which are screwed into the fixing slots 22 of the local fixing elements 21. Prior to screwing, the three local fixing elements 21 are positioned on the side posts 31 at the required locations. To do this, the connecting portion 25 of the fixing elements 21 is inserted into the rail 23 of the posts 31, each of which is made of a profile 20. Each local fixing element 21 is then slid into the rail 23 to the required location. They are held in position there by the retaining means (friction, adhesive, notching, etc.). Depending on the embodiment implemented, screwing a screw 32 into the fixing housing 22 of a fixing element 21 can cause it to press against the walls of the rail 23 and thus contribute to maintaining it in position in the rail 23.
[0117] Various embodiments of the examples described above are possible.
[0118] A local fastening element may, for example, include several fastening locations and thus allow the installation of several screws.
[0119] A profile could also include several rails, each equipped with one or more cores.
[0120] Several local fixing elements can be attached to the same rail.
