Description

"Hardware and manufacturing process for frames and joinery, in particular arched metal"

The present invention relates to a functional hardware device within a carpentry device, more particularly, for a connection between at least two movable door elements relative to each other.

It also relates to a carpentry device or door frame comprising such a hardware, and a method of producing such a door frame device.

In the building sector, woodwork refers to elements or groups of elements, previously made of wood, forming the layout of openings, fixed or mobile. When they include moving parts, these joineries can be called door frames, for example a door block or a window block.

These joineries often include one or more frames, forming or retaining a transparent or opaque panel. On this frame is fixed one or more functional devices, often called hardware stores, for example for the pivoting of an opening or the support of a blind. To date, the various parts (opening, fixed or fixed) bent joinery (for example metal and especially aluminum) existing on the market are made in one piece, for example by bending and welding profiles obtained by molding or extrusion. The hardware stores are reported on the profiles. This type of embodiment has a certain number of drawbacks, in particular in terms of complexity and manufacturing cost, and imposes structural constraints that can have detrimental consequences in terms of uniformity and aesthetics.

An object of the invention is to overcome all or part of the disadvantages of the prior art.

In particular, it aims to simplify and make faster or more flexible or more economical the manufacture and assembly of joinery, and to obtain structures allowing new choices in aesthetics. It can also be useful to improve or optimize burglar resistance.

To achieve this goal, the invention proposes a new type of functional block, or hardware, for the realization of a carpentry device. According to the invention, this functional block comprises, in addition to its known functionalities, assembly means for joining together at least two segments of said carpentry device. The segments can be fixed on these assembly means in different ways, for example as described below or by known methods such as welding.

Such an assembly functional block may be monoblock, and include integrated parts performing this assembly function (internal reinforcement, sleeve, ring, plate, or other connecting piece)

It can also be multi-block, that is to say using several pieces to produce the assembly means (for example an assembly block which will be fixed at the same time to the functional block and to the segment to be assembled)

In the case of a joinery comprising one or more moving parts, the invention further proposes that such a functional block, called assembly block, makes a connection between at least two moving frame elements with respect to the other.

In a first embodiment, the assembly functional block comprises at least one reinforcement on which the assembled segments are fixed and the major part of which is engaged in at least one chamber of each of said assembled segments. In a second embodiment, the assembly means may comprise at least one reinforcing or holding part intended to extend inside a chamber of a profile belonging to one of the segments to be joined.

Alternatively, the assembly means comprise at least one mounting plate, or an open portion forming a sleeve adapted to receive an end of at least one of the segments to be secured.

In the context of the invention, these two variants of assembly means can be combined with one another or with other types of assembly. means of assembly, within the same carpentry or on the same functional block.

The invention also includes such a carpentry device, fixed or with moving parts. According to the invention, the assembly blocks described here can also be used to produce a bent joinery from several segments, independently of the functionalities other than the assembly. A simple fixed joinery without functionality can for example be carried out with a segment closed by an assembly block, or two segments assembled by two assembly blocks, for example assembly blocks formed by simple hidden reinforcements as described herein.

According to the same inventive concept, there is provided a method of making joinery, in particular curved metal, characterized by the assembly of at least two segments of profiles by means of assembly elements according to the invention.

This method may be more particularly applied to a door frame device comprising at least a first element and a second element movable with respect to one another and interacting with respect to one another by at least one device. functional block, or hardware, said second element comprising at least two segments.

This process then comprises the following steps:

- assembling the functional block with said first element;

assembling at least a first segment of the second element with said functional block; assembling at least a second segment of the second element with said functional block.

More particularly, this method applies to a device for which the second element comprises a frame including the first and second segments. This method then further comprises a step of inserting at least one obstruction element inside said frame, wherein said obstruction element is retained by the assembly of the second segment.

In the same spirit, the invention further provides a method of manufacturing door frames comprising the use of at least one defined assembly functional block model according to the invention, for producing a plurality of types of door frames, by assembling with segments of a plurality of different types. This method then comprises: a supply of a quantity of a given model of such an assembly functional block, and a quantity of segments of several different types; and

On the other hand an iterative repetition of assembly cycles each comprising a selection step, depending on a type of carpentry device or frame to obtain for this cycle, types of segments to assemble.

These processes are particularly intended for the production of arched metal joinery, including aluminum but also any profile with a metal structure, regardless of its finish. Other features and advantages of the invention will emerge from the detailed description of an embodiment which is in no way limitative, and the appended drawings in which:

FIG. 13 represents an embodiment of the invention in the form of a basket handle frame.

The prior art is typically illustrated in FIG. 1. This figure shows a tilting frame with a glazed opening of circular shape.

The frame device 1 comprises an opening 12 movable, tilting about a horizontal central axis 10 relative to a frame 11 remaining fixed to the wall. The frame 11 is a circular frame made by bending a profile through 360 °, then by straightening and welding 110 of the two ends together.

The opening 12 is a circular frame made by bending a profile over 360 °, then by straightening and welding 120 of the two ends together. The interior of the opening is closed by a glazing 10, maintained on a rabbet opening by parecloses 101.

On the frame 11 and the opening 12 are fixed two hinge devices 15 and 16, for example by screws 151, 152, 161, 162. The locking in the closed position is by a bolt 13 mounted on the frame, for example by a plate screwed on the face of the frame. This bolt 13 engages in a keeper 14 mounted on the opening 12, for example by embedding in its thickness.

In FIGURE 2 to FIGURE 3c is illustrated an exemplary embodiment of the invention, for a door frame device adapted to replace that of FIGURE 1.

The frame 21 is a circular frame formed by three segments 211, 212 and 213, assembled together by three functional blocks 23, 25 and 26. Two of these functional blocks are hinge-type functional blocks 25 and 26, and the other is a bolt block 23.

The opening 22 is a circular frame formed by three segments 221, 222 and 223, joined together by these two hinge function blocks 25 and 26, as well as a striker block 24 making the locking with the bolt block 23. The interior of the opening 22 is closed by a glazed panel 20 held in a groove 201 located on the inner edge of the opening 22.

FIGURE 3a, and FIGURE 3b show in more detail one of the hinge functional blocks of the embodiment of FIGURE 2.

The hinge functional block 25 comprises a first part 251, called outer, provided with assembly means with the segments 211 and

212 of the frame 21. This outer portion is intended to be engaged with the wall or the wall 200 on which the frame 2 must be placed, for example by a rabbet 255. In this example, the outer portion 251 comprises a substantially parallelepiped-shaped half-block forming an outer reinforcement 2510 which is engaged in recesses borne by the ends of the segments to be assembled, for example in a chamber (interior space of a hollow profile) in the case of segments made of hollow sections. On its face vis-à-vis the frame of the frame, the outer reinforcement 2510 2516 has cut sides that allow its insertion in segments having a certain curvature. These cut sections also allow a compatibility of such reinforcements with different forms of segments to be able to achieve different forms of chassis.

In this example, the assembly means comprise the portion of the outer reinforcement 2510 engaging inside the profile and a fastening mechanism. Here, this mechanism is formed by a plate 2511 inserted inside the segment 211 and traversed in an oblong hole 2513 by a clamping screw 2514. This clamping screw is substantially longitudinal to the segment 211 and screwed into a threaded hole 2515 of the external reinforcement 2510. The ends of the plate 2511 are supported in notches or lights 2111 provided on the outer and inner edges of the segment 211 which will subsequently be concealed respectively by the wall and the opening, or on non-visible walls of the chamber receiving the external reinforcement 2510. When tightening the screw 2514, the plate 2511 brings the end 2112 of the segment 211 of the outer reinforcement 2510 closer together so that it abuts on another segment 212 assembled on the same outer reinforcement is on a part of the protruding half-block, for example a rib 2512 or a lug interacting with the segment 211 in a manner similar to the plate 25 11.

On this outer part 251 is articulated a second part 252 comprising another half-block forming an internal said reinforcement 2520, for example of the same type as the outer reinforcement 2510 of the outer part 251. These two outer reinforcements 2510 and 2520 inner are assembled between them by a pivot forming a hinge about the axis A2, for example by a bolt 250 passing through and holding them on either side of a friction ring 259 forming a spacer. On the inner reinforcement 2520 are fixed the ends of the segments 221 and 222 of the opening 22, similarly to the fixing of the segments 211 and 212 of the frame 21 on the outer reinforcement 2510.

As illustrated in FIGURE 2, the bolt 23 and keeper blocks 24 are each made with a reinforcement similar to the halfblocks 2511 and 2521 of the hinge block 25 described above. These reinforcements are attached to the segments assembled in a similar manner, ie the segments 212 and 213 for the bolt block 23 and respectively the segments 222 and 223 for the striker block 24. It should be noted that this embodiment makes it possible to have only very little surface of the reinforcement 2511 which is visible after assembly, for example the only rib 2512, which may be of width not exceeding 4mm or even 1 or 2mm. In the case where the segments rest on one another, only the slot left between the ends of the assembled segments will be visible.

Similarly, the articulation of the outer reinforcements 2511 and inner 2521 located in the plane of the opening and the frame allows to obtain a chassis of a more refined appearance where the hinges are not visible, and where the bulk of the hardware 23, 24, 25 and 26 is hidden in the profiles.

In FIGURE 4 to FIGURE 5c is illustrated another exemplary embodiment of the invention, for a door frame device adapted to replace that of FIGURE 1.

The frame 31 is a circular frame formed by three segments 311, 312 and 313, joined together by three functional blocks 33, 35 and 36. Two of these functional blocks are hinge-type functional blocks 35 and 36, and the other is a bolt block 33.

The opening 32 is a circular frame formed by three segments 321, 322 and 323, assembled together by the same two hinge function blocks 35 and 36, as well as by a striker block 34 effecting the locking with the bolt block 33. Inside the opening 32 is closed by a glazed panel 30 held in a groove 301 located on the inner edge of the opening 32. FIGURE 5a, FIGURE 5b and FIGURE 5c show in more detail one of the hinge functional blocks of the embodiment of FIGURE 4.

The hinge functional block 35 comprises a first portion 351, called outer, provided with assembly means with the segments 311 and

312 of the frame 31. This outer portion is intended to be engaged with the wall or the wall 300 on which the frame 3 must be placed, for example by a rabbet 355.

In this example, these assembly means consist of protruding portions 353 and 354 forming reinforcements coming into recesses borne by the ends of the segments to be assembled, for example in chambers (interior space of a hollow profile). in the case of segments made of hollow sections.

On this outer part 351 is articulated a second part 352, called inner, provided with assembly means, formed of reinforcements 356 and 357, with the segments 321 and 322 of the opening 32. This inner part bears on its inner edge a groove 358 adapted to receive and retain the glazing 30.

In this example, the outer 351 and inner 352 parts are connected by an axis formed by a screw 350 passing through the outer portion 351 and fixed in the inner portion 352.

There will now be described a method for producing joinery according to the invention.

In the present invention it is possible to cut profiles if they have already been bent into a complete part, or more simply to directly bend profile segments to the desired shape.

This method makes it possible to use assembly elements that can ensure both the connection of these profile segments, and the function of hardware parts. The assembly elements that it allows can also be of all types (reinforcements or blocks "I" assembly will be recommended in the case of profiles with chamber open sleeves, rings, plates or other visible elements may be used in the case of profiles without room). FIG. 6 illustrates an exemplary method of manufacturing a tilt frame device 2 as previously described with reference to FIG. 2 and FIG. 4.

This figure shows the different assembly steps of the frame 3 of FIG. 4 in a diagrammatic view from the left, but the method can also be applied to the frame of FIG. 2. In this example, it is a a tilting glazing frame with chamber profiles and without glazing glazing, made using tilting blocks 35 and 36 (in this case, these are two assembly elements of the type of the functional block 35 of FIG. 5 , which is composed of assembly means such as an outer reinforcement 353, 354 intended to receive the two parts of the frame 31, connected by an axis 350 to an inner reinforcement 356 and 357, intended to receive the two parts of the opening 32).

It is necessary to bend segments 311, 312 and 313 forming two half-dormant and segments 321, 322 and 323 forming two half-opening.

These different segments 311, 312, 313, 321, 322, and 323 are made for example from metal profiles cut and bent according to known techniques. The two upper segments 311 and 321 are bent substantially half circles, and the four lower segments

312, 313, 322 and 323 are bent substantially in quarter circles.

In a step 1 of the method, it is first necessary to assemble the two parts of the frame 31 by making them penetrate into the external assembly means, for example external reinforcements 353 and 354. Thus, an assembly of the three segments is made. 311, 312 and 313 with the outer parts 351 and 361 of the two functional and assembly blocks 35 and 36 of the hinge type, as well as with the functional block bolt 33, to form the frame 31.

In a step 2, the inner portions 352 and 362 of the functional blocks 35 and 36 carrying inner assembly means, for example inner reinforcements 356 and 357 connected by a pivot 350 to the outer reinforcements 353 and 354, are then inclined in order to allow them to receive the lower part of the opening 32 which must, before or after this operation, receive the glazing 30. This pivoting also allows to release access to their upper assembly means 356 and their lower assembly means 357.

A step 3 then comprises an assembly of one of the parts of the opening 32. Preferably it will be the lower half-opening, formed by assembling the segment 322 with the block 35 and the segment 323 with the block

36, these segments being assembled together by the striker block 34, designed to cooperate with the bolt block 33, and its assembly means 357.

A step 4 then comprises the insertion of the glazing 30, so as to rest in the lower part of the groove 301 carried by the inner edge of the lower segments 322 and 323 of the opening.

In a step 5, it is then necessary to bring the upper part of the opening 32 and adjust it on the inner reinforcements 356 located upwards. The assembly of the upper segment 321 is thus carried out on the upper assembly means 356 of the hinge blocks 35 and 36, thus completing the frame of the opening 32 and trapping the glazing 30 in the upper part of the inner groove 301 of this opening.

The glazing 30, or any other type of obstruction element is thus retained in the context of the opening 32 without the need to add additional parts such as parecloses 101 of the prior art (FIGURE 1). It will then be possible to install the finishing elements (seals, peripheral beadings, etc.).

To obtain an opening glazing frame, ie with lateral hinges as illustrated in FIGURE 8 or FIGURE 9, it will be necessary to assemble the frame 61 and the opening 62 with, on one side, a hinge block 65 (FIG. composed of an external reinforcement 651 connected to an internal reinforcement 652 by a hinge 650), and the other a latch block or a bolt block 63 for the opening and a striker block 63 for the frame.

In addition, the invention makes it possible to produce different joineries as in FIGURE 10 and FIGURE 11 from the same type of functional blocks 85 and 86, by choosing at the last moment the type of segments to be assembled, for example when step 1 (assembly of the frame) and step 4 (insertion of the glazing), as well as step 3 (lower half-opening) or step 5 (upper half-opening). It is therefore possible to optimize the manufacture of several types of woodwork to choose at the last moment, while limiting the stocks of functional blocks.

This method is valid for all types of bends, all types of profiles and all types of chassis, and the different variants described here can be combined with each other without departing from the scope of the invention.

Other variants will now be described, which can be combined with or within the invention as previously described.

In FIGURE 7a is shown a variant of an assembly functional block as described in FIGURE 5. The assembly means here comprise recesses 553, 554, and respectively 556 and 557, carried by the outer portions 351 and respectively inner 352 of the hinge functional block 35. Once assembled, each of these recesses receives a projecting portion of the segment with which it is assembled, for example a portion having a substantially complementary shape and located at the end of this segment.

In FIG. 7b, the assembly means comprise removable or attached elements engaging in the recesses 55, 554, 556 and 557 as shown in FIG. 7a, for example "I" blocks 563, 564, 566 and 567 made by cutting an "I" profile.

Other types of assembly means can of course be provided, for example fixing plates located on the hidden side of the segment to be assembled.

The method and the functional devices according to the invention thus make it possible to produce different types of door frame devices.

In the case of a tilt-frame type frame 2 or 4 as shown in FIGURE 2 and FIGURE 4, the functional blocks 25, 35 and 26, 36 are "tilting blocks" with a dual function uniting the elements of FIG. assembly and the pivot about the central axis A2. That is to say that the connecting element 251, 351 of the frame 21, 31 and the connecting element 251, 351 of the opening 22, 32 are joined by an axis 250, 350 or any effect part rotation, allowing the opening to be fixed to the frame and can switch without the contribution of another piece of hardware (other than that achieving the assembly of segments). As illustrated in FIGURE 8, in the case of a frame 6 of the side window type, the functional block 65 is a "hinge block" with a dual function joining the assembly and hinge elements.

That is to say that the connecting element 651 of the frame 61 and the connecting element 652 of the opening 62 are joined by any type of hinge 65O ₇ thus allowing the door to be rotated without requiring the supply of another piece of hardware. Indeed, it is then the hinge functional block (s) 65 and the bolt block 63 which assemble the segments 611 and 612 forming the frame 61. Likewise, it is the hinge functional block (s) 65 and the block strike 64 which assemble the segments 621 and 622 forming the opening 62.

In FIGURE 12 is illustrated an embodiment for a fixed frame, made with an assembly functional block joining two segments formed of the two ends of a profile 92 bent into a complete circle. In this example, this assembly block 92 combines both the assembly function of the ends and the support function of a pull-out blind 93.

As illustrated for example in FIGURE 2 (blocks 25 and 26), FIGURE 10 (blocks 85 and 86) or FIGURE 8 (block 65), it will be appreciated that the assembly functional blocks can be made in such a way that the exposed parts are extremely small, especially between the ends of two assembled segments. This is particularly true in the case where the assembly means are made by reinforcements entering the profiles. As illustrated in FIGURE 9 to FIGURE 12, this method also allows the realization of many different types of blocks or frames, and for example:

- a half opening on a circular frame (FIGURE 11);

a semicircular frame, for example a half-moon frame (FIGURE 10);

- a window frame (FIGURE 12),

- a frame in basket handle (FIGURE 13).

In the same spirit, it is possible to make and use functional blocks including other functions known elsewhere by example, a latch block, a compass block, or a lock block. Such functional blocks then have the dual function of assembling on the one hand an assembly element and, on the other hand, respectively, a latch, a compass or a lock. That is to say by adding, to an assembly element, the function of one of these pieces of hardware as they are currently known.

This invention brings greater simplicity, better flexibility and a reduction in manufacturing costs and even manufacturing times, in particular for the following reasons.

It also brings different solutions increasing the freedom of design including in the field of aesthetics.

It reduces the bending required to achieve the same final forms of joinery, thus reducing the constraints and costs specific to this operation.

It becomes possible to avoid the straightening operation required in the prior art by the deformation of the profile on the last part of its circumference (caused by the "overlapping" of the sleeves at the end of complete bending).

It can eliminate the need for welding to connect these ends, as well as the sanding that results. It avoids, in some cases, the use of bead to maintain the glazing, when the assembly of the two profiles of the opening takes place after the positioning of the glazing.

Hardware stores can be more economical, since they have dual functions. They can also be left largely raw, or require less finishing since they can be designed to have fewer apparent surfaces. For example, it is possible to avoid surface treatment on concealed parts.

The ability to conceal all or most of the hardware in the profiles also allows greater style freedom and aesthetic gain.

Compared to designs previously using parecloses, their removal brings a gain in brightness by increasing the glazing area. It is possible to design frames having several segments interchangeable with each other, which limits the disadvantages of storage. For example, within tilting chassis, it is possible to use the same profiles for the lower part and the upper part when the half-opening has the same dimensions.

Of course, the invention is not limited to the examples that have just been described and many adjustments can be made to these examples without departing from the scope of the invention.
