ASSEMBLY METHOD OF AN OPENING ELEMENT WITH ADJUSTABLE LENGTH, AND KIT FOR AT LEAST ONE OPENING ELEMENT WITH ADJUSTABLE LENGTH

Description

FIELD OF THE INVENTION

[0001] The present invention relates to the field of openings, also called leaves or gates, and more precisely to the field of openings for gates such as those that can be found in private gardens. TECHNOLOGICAL BACKGROUND

[0002] More specifically, the invention relates to a method of mounting an opening which can be carried out by an individual who does not have any particular skills or tools for mounting such an opening.

[0003] Generally speaking, a gate comprises two posts fixed rigidly and securely in the ground, for example using a concrete slab, an opening, a connection between the opening and the posts, and a mechanism for actuating the opening. However, the invention is also suitable for the case in which the opening is intended to remain fixed between the posts, so as to provide a definitive closure, the actuating mechanism then being absent in this case.

[0004] Typically, the opening is made up of stiles and rails fixed together. A filler fills the space between the rails.

[0005] In the field of gates, it is known to offer openings in kit form, so that the user, generally an individual wishing to install a gate at home, for example at the entrance to their garden, can assemble the gate themselves. Thus, the opening is delivered in separate parts to the user, facilitating the packaging and transport of the opening. The user must then themselves carry out the assembly of the different parts of the opening and their installation between the posts. Document EP 2 492 435 describes an example in which the frame of a leaf is delivered in kit form to a user, who assembles the elements themselves, in particular by being able to choose the orientation of the crosspieces in relation to the uprights. Document US5868382 describes a vinyl gate structure.

[0006] However, such a solution is tedious to implement by the user, who must ensure and adjust the correct orientation of the crosspieces himself.

[0007] Furthermore, in such a solution, the position of the posts between which the sash is intended to be mounted is determined by the length of the sash, so if the posts are already installed, such a solution is inadequate.

[0008] There is therefore a need to provide a solution, in particular to the aforementioned drawbacks. SUMMARY OF THE INVENTION

[0009] Thus, according to a first aspect, the invention relates to a method of mounting an opening of adaptable length, in particular for a gate between two fixed posts, according to claim 1.

[0010] The method further comprises, before fixing the sleepers to the second upright, fixing a filler between the two sleepers. Each sleeper is provided with a filler groove extending along the length of each sleeper. The filler grooves of the two sleepers are opposite each other when the sleepers are fixed to the first upright. The filler is inserted by sliding into the filler grooves between the two sleepers. The fixing to the second upright ensures that the filler is held in position between the two sleepers.

[0011] According to one embodiment, the filling comprises at least one solid panel. The method then comprises calculating a suitable length for the panel based on the distance between the posts, and cutting the filling panel to the suitable length. Thus, it is not necessary to cut a plurality of elements to fill the space between two facing crosspieces. The filling panels are made of a material particularly suitable for cutting by the user.

[0012] According to one embodiment, the filling comprises, alternatively or in addition to a solid panel, a plurality of stacked bars or slats.

[0013] According to one embodiment, the opening comprises at least three crosspieces, each crosspiece being fixed at a different height on the uprights and at least two filling panels, each panel being fixed between two crosspieces. Thus, the user has five elements to cut per opening, namely two filling panels and three crosspieces, to obtain a complete opening, ready to be mounted between two posts, of suitable length.

[0014] According to one embodiment, each crosspiece has two ends and two reference marks to identify each end, each reference mark having a unique correspondence on only one of the uprights. The assembly of the crosspieces to the uprights is thus guided, limiting the risks of incorrectly positioning the crosspieces on the height of the uprights.

[0015] According to one embodiment, the crosspieces are fixed to the uprights by screwing. The fixing can thus be easily carried out by the user using common tools.

[0016] According to one embodiment, the crosspieces are screwed onto the uprights by inserting screws into an outer face of each upright, the screws passing through an inner face of the upright. The screws are thus easily put in place through the outer face of the uprights, which is fully accessible, the crosspieces being in contact with the inner face of the uprights.

[0017] According to one embodiment, at least one upright includes two tabs extending on either side of the outer face over the entire height of the upright. The method then includes fixing a closure to the tabs by snap-fastening, masking the screws. The aesthetics of the final gate are thus enhanced. The screws are masked, in order to protect them from external elements, but also from malicious attempts at intrusion.

[0018] At least one upright comprises two legs extending on either side of the inner face over the entire height of the upright. The method then comprises fixing a closure provided with a rebate on the legs of the upright by snap-fastening. The rebate can then come into abutment against an upright of another opening, in order to provide closure of a possible space between the uprights of two openings of a gate.

[0019] According to one embodiment, at least one of the crosspieces comprises a reinforcement bar for fixing the motorization.

[0020] According to a second aspect, the invention relates to a kit for at least one opening of adaptable length according to claim 9. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] On the figure 1 , a portal is represented 1 including two openings 2of adaptable length in accordance with an embodiment of the invention. The two openings 2 are installed in order to provide a closure between two posts 3 already installed, for example fixed to the ground in concrete slabs.

[0024] By adaptable, we mean here the property of the openings to be able to be installed between posts between which the distance L is not known at the time of manufacture of the elements making up the opening 2.

[0025] Each opening 2 includes at least two uprights 4, and at least two sleepers 5. Depending on the method of implementation of the figure 1 , each opening 2 comprises three crosspieces 5. When the space between two adjacent crosspieces 5 does not provide a sufficient level of anti-intrusion security, a filling can fill the space between the two uprights 4 and the crosspieces 5 two by two of each opening 2. In the example of the figure 1 , the filling comprises solid panels 6. However, the filling may comprise grid bars, a mesh, or any other suitable element such as a plurality of stacked bars or slats. According to one embodiment, the filling panels 6 comprise a central layer of high-density foam pressed between two aluminum sheets.

[0026] In the following, the adjectives horizontal and vertical, as well as their variants, should be understood in reference to the natural orientation of the figure 1 , in which the posts and uprights are vertical, and the crosspieces are horizontal, substantially orthogonal to the uprights and posts.

[0027] However, this orientation is in no way limiting of the invention. In particular, the crosspieces may not be perpendicular to the uprights; the uprights may also not be vertical.

[0028] Each upright 4 extends in a longitudinal direction, which is substantially the same as the vertical direction according to the embodiment of the figure 1 , between two ends, called end 4a upper and end 4b lower, with reference to their position in the vertical direction when the openings 2 are assembled to the posts 3. The dimension of the uprights 4 between the two ends 4a and 4b is called height.

[0029] The crosspieces 5 extend in a longitudinal direction, which is substantially the same as the horizontal direction according to the embodiment of the figure 1 , between two ends 5a, 5b. The dimension between the two ends 5a, 5b of the crosspieces is called length.

[0030] An example of the construction of the uprights 4 and the crosspieces 5 will now be described.

[0031] Each upright 4 is in the form of a profile, for example made of steel or aluminum or plastic and for example obtained by extrusion. Thus, the section of each upright 4 is the same over the entire height of the upright 4. According to the embodiment presented here, the two uprights 4 of an opening are identical, facilitating stock management and reducing manufacturing costs. However, it may be otherwise. Each upright 4 thus comprises a core 7, of substantially rectangular or square section. In order to save material, the core 7 may be hollow, and may include ribs and grooves in the hollow in order to provide the required mechanical resistance, particularly in terms of bending and buckling.

[0032] The core 7 comprises four exterior faces, that is to say oriented towards the outside of the hollow, and designated as a face 7a interior, one side 7b exterior and two sides 7clateral connecting the inner face 7a to the outer face 7b. The upright 4 comprises two legs 8, each extending in the extension of a lateral face 7c, on either side of the inner face 7a. The minimum distance between the legs 8 is greater than or equal to a dimension of the crosspieces 5 other than their length, as will be explained later.

[0033] Amount 4 also includes two tabs 9 each extending in the extension of a lateral face 7c, on either side of the external face 7b. The free end 9a of the two tabs 9 are opposite each other, the two tabs 9 and the outer face 7b forming a C, and are shaped to allow the snap-fastening assembly of a closure, as will be seen later.

[0034] The legs 8 and the tabs 9 are preferably aligned with the lateral faces 7c which they extend, so that a person placed in front of one of the lateral faces 7c sees only a single continuous face, for a pleasant visual rendering of the upright 4.

[0035] Each crosspiece 5 is in the form of a profile, for example made of steel or aluminum or plastic and is for example obtained by extrusion. Thus, the section of each crosspiece 5 is the same over the entire length of the crosspiece 5. According to the embodiment presented here, each crosspiece 5 also comprises a core 10of substantially rectangular section, and hollow in its center. Ribs and / or grooves may be provided on the core 10 in its center in order to provide the required mechanical resistance, particularly in terms of bending. The core 10 of each crosspiece 5 then comprises an upper face 10a, a lower face 10b and two lateral faces 10c connecting the upper face 10a to the lower face 10b. The dimension of the crosspiece 5 measured between the two lateral faces 10c is less than or equal to the minimum distance between the legs 8 of the uprights 4.

[0036] The crosspieces 5 may be identical, but not necessarily. In particular, in the case where the opening 2 comprises three crosspieces 5, namely an upper crosspiece, a lower crosspiece and an intermediate crosspiece placed between the upper crosspiece and the lower crosspiece according to the height of the uprights 4, the intermediate crosspiece 5 must allow the assembly of two filling panels 6, while each of the upper crosspiece 5 and the lower crosspiece 5 must only allow the assembly of one assembly panel 6.

[0037] On the figure 3 , an example is shown for an intermediate crosspiece 5, which must therefore allow the assembly of two filling panels 6.

[0038] Crossing 5 of the figure 3 thus comprises two pairs of arms 11 extending in the extension of lateral faces 10c of the web 10 of the crosspiece 5. More precisely, the two arms 11 of a first pair extend on either side of the upper face 10a and two arms 11 of the second pair extend on either side of the lower face 10b. The free ends of the arms 11 of a pair are opposite each other, so that the arms 11 form a C with the upper face 10a or the lower face 10b which they frame.

[0039] The distance between the free ends of the arms 11 of a pair defines the maximum thickness of the filling panel 6. Preferably, the thickness of the panel 6 is substantially equal to the distance between the free ends of the arms 11 of a pair.

[0040] In order to ensure optimal support of the panel between the arms 11, ribs 12can be provided as projections on the face 10a and on the lower face 10b. The ribs 12 define with the arms 11, for each face 10a, 10b, a filling groove, to allow a filling panel 6 to be inserted therein.

[0041] In order to reinforce a crosspiece 5, and generally this is the intermediate crosspiece 5, to fix a motorization for actuating the opening, a bar 13 reinforcement bar can be assembled on the crosspiece 5. For example, the reinforcement bar 13 is a bar, for example made of steel or aluminum, slid into the hollow of the web 10 of the crosspiece 5, on a face opposite one of the lateral faces 10c. The thickness of the reinforcement bar 13 is greater than the thickness of the wall of the web 10 of the crosspiece 5.

[0042] The core 10 further has receiving members 10d extending into the hollow of the core 10, these receiving members 10d being provided to allow tightening by screwing with the uprights 4 as will be seen later.

[0043] It is immediately understood that since the upper crosspiece 5 and the lower crosspiece 5 only cooperate with a filling panel 6, they can each have only one pair of arms 11. More precisely, the upper crosspiece 5 does not comprise an arm 11 framing the upper face 10a, and the lower crosspiece 5 does not comprise an arm 11 framing the lower face 10b. No reinforcement for fixing the motorization is furthermore required on the upper crosspiece 5 and the lower crosspiece 5.

[0044] The opening 2 further comprises a closure for each upright, intended to close the opening between the ends 9a free of tabs, as will be explained later. When the opening is intended to be pivoted relative to a post 3, two types of closure are provided: a first type of closure 14 said simple, represented on the figure 4 , and a closure 15 said to be beaten, represented on the figure 5 . The simple closure 14 is for example a profile obtained by extrusion, in steel, aluminum, or plastic, and comprises two legs 14a snap-in, which are shaped and sized to snap between the tabs 9 of the uprights 4. The legs 14a of the simple closure 14 have a flexibility suitable for obtaining the snap-in. The simple closure 14 further comprises a cap 14b connecting the two legs 14a and intended to cover the opening between the legs 9 of the uprights 4.

[0045] The 15-beaten closure is substantially similar to the simple 14 closure, in that it has legs 15a to snap between the tabs 9 of an upright 4, and a hat 15b substantially flat intended to cover the space between the tabs 9 of the upright 4. However, it additionally comprises a flap 15c, extending in projection from the cap 15b. The flap 15c may have at its free end a claw 15d intended to engage with an element of an upright 4 of another opening 2 in order to ensure good closure between two uprights 4 of the two openings 2 of the gate 1.

[0046] An example of the assembly process of an opening 2 of adaptable length of the figure 1 will now be described.

[0047] A kit for opening 2, that is to say a set comprising the components of the opening 2 unassembled, is delivered to a user in separate parts. In particular the two uprights 4, the three crosspieces 5, the two filling panels 6 and the closures 14, 15 are not assembled. The dimensions of these elements are standard, they are not personalized by the user at the time of ordering. The screws necessary for assembly are also provided. A user manual is advantageously provided with the opening 2. In practice, a gate generally comprising two openings 2, the kit includes the components to mount the two openings 2.

[0048] By user, we mean an individual, not an expert in the field of gate installation, who wishes to install a gate, for example, at the entrance to their home.

[0049] First, the user measures a transverse distance L, approximately horizontal, between the two posts 3 already installed between which he wishes to install the gate 1. This distance L between the two posts determines the rest of the operations.

[0050] The instructions indicate a calculation to be carried out from the measurement L, in order to determine the length of the crosspieces 5. Indeed, the length of the crosspieces 5 must take into account the fact that they are not in direct contact with the posts. In particular, the calculation of the length of the crosspieces 5 takes into account the dimension of the uprights 4. The instructions are preferably produced in such a way that only the length L between the posts must be measured by the user, the other necessary dimensions being already known.

[0051] Thus, the user makes a simple calculation to obtain a suitable length of the crosspieces 5 of the opening 2. This is typically a subtraction from the length L between the posts 3 of the dimensions to be taken into account, the whole being divided by two in the case where the gate 1 includes two openings 2.

[0052] Then, the user cuts each sleeper 5 to the appropriate length, calculated previously. This length is generally the same for all sleepers 5.

[0053] It may be provided to cut each crosspiece 5 to a specific length, different from those of the other crosspieces 5, to obtain an opening deviating from the general rectangular shape. The instructions then include instructions for calculating the length of each crosspiece 5 for this purpose.

[0054] Similarly, the instructions indicate a calculation to be carried out in order to obtain a suitable length for the infill panels 6. The other dimension of the panels 6, namely their height, is not modified in this embodiment. This calculation can be made from the measurement L of the length between the two posts 3, or from the suitable length calculated for the crosspieces 5. The calculation of the suitable length of the infill panels 6 is again simple, being a subtraction and possibly a division by two.

[0055] The use of solid infill panels 6 is particularly suitable for the process involving the cutting of the infill. Indeed, most known gate openings comprise a plurality of stacked bars or slats, so that a step involving the cutting of all these elements would be tedious for the user. Thanks to the solid panels, the number of elements to be cut is limited, in this case to two panels 6 according to the embodiment of the figures, per opening 2. In addition, the production of the panels 6 which comprise a central layer of high-density foam pressed between two aluminum sheets makes it easy to cut the panels 6 to the correct length for a user equipped with general public, non-specific tools.

[0056] Then, each crosspiece 5 is fixed to a first upright 4. More precisely, a first end 5a of each crosspiece 5 is inserted between the legs 8 of the first upright 4 until it comes into abutment against the inner face 7a of the upright 4. Then one or more screws are inserted between the first upright 4 and each crosspiece 5.

[0057] For this purpose, the upright 4 may include holes provided for the insertion of screws, the holes passing through the inner face 7a and the outer face 7b of the web 7 of the upright 4 to cooperate with the receiving members 10d of the corresponding crosspiece 5. The screws are preferably self-tapping, so as to form the thread in the receiving members 10d of the crosspieces 5 to ensure tightening. The position of the screws on the upright 4 is provided to be in conformity with the height of the infill panels 6. The screws are manipulated from the outer face 7b of the second upright 4, which is easily accessible to the user. The screws are suggested by broken lines on the figure 7

[0058] Advantageously, in order to facilitate the positioning of the crosspieces 5 on the height of the uprights 4, a system of locating marks is provided, in which the two ends 5a, 5b of the crosspieces 5 are identified, for example A, D for a first crosspiece 5, B, E for a second crosspiece 5 and C, F for a third crosspiece 5, as illustrated in the figure 7 . Each upright 4 then also includes three reference marks, each corresponding to a single mark on a single crosspiece 5. For example, the first upright 4 includes the marks A, B, C, distributed over its height, at the location where the screws are intended to be inserted, and the second upright 4 includes the marks D, E and F, distributed over its height, at the location where the screws are intended to be inserted.

[0059] The reference marks are for example carried by labels stuck on a single lateral face 7c of the uprights 4 and a single lateral face 10c of the crosspieces 5 before delivery to the user. They can however be stuck by the user according to the instructions provided in the instructions. The marks of the crosspieces 5 are either distributed at regular intervals along the length of the crosspiece 5, or are easily repositionable, so as to be visible even after cutting to the appropriate length.

[0060] Thanks to the system of reference marks, the user can easily place the crosspieces 5 each at the correct height on the uprights 4. In addition, positioning errors are avoided. Thus, for example, a crosspiece 5 intended to be an intermediate crosspiece will not be positioned like a crosspiece 5 intended to be an upper or lower crosspiece. Similarly, errors in the orientation of the crosspieces are limited. For example, the crosspiece 5 intended to be the upper crosspiece will be correctly oriented so that its single filling groove formed by the arms 11 and the ribs 12 is opposite a filling groove of the intermediate crosspiece. The same is true for the lower crosspiece 5.

[0061] Each filling panel 6 is then slid between two crosspieces 5, in the filling grooves opposite the two crosspieces 5.

[0062] Then, the crosspieces 5 are fixed to the second upright 4, following the reference marks. The second end 5b of the crosspieces is brought into contact with the inner face 7a of the second upright 4. One or more screws are inserted between the second upright and each crosspiece 5 in the same manner as described for the first upright 4, ensuring the clamping between the second upright 4 and the crosspieces 5. Thus, as for the first upright 4, the screws are manipulated from the outer face 7b of the second upright 4, which is easily accessible to the user.

[0063] The filling panels 6 are thus at this stage trapped between the crosspieces 5 and the uprights 6, and can no longer be removed except by dismantling an upright 4. The filling can alternatively be bars of a grid, or a wire mesh element or any other element suitable for closing the space between the crosspieces 5.

[0064] The legs 8 of the uprights make it possible to hide the connection between the uprights 4 and the crosspieces 5 and partially cover the filling panels 6, limiting the risk of damage, for example in the event of an attempted break-in.

[0065] Thus, according to another aspect independent of the first aspect presented above, an invention relates to a method of mounting an opening 2 according to claim 1, in particular for a gate, between two posts 3 fixed, opening it 2 can be fixed, pivoting or sliding relative to the posts 3, the opening 2 comprising at least two amounts 4 and at least two sleepers 5, panels 6, bars or slats extending between the two uprights 4, the method comprising: the measurement of a distance L transverse between the two posts 3 ; the calculation of a suitable length for each sleeper 5,sign 6, bar or blade depending on the distance L measured between the two posts 3 ; the cutting of each crosspiece 5, sign 6, bar or blade to the appropriate length; the insertion of a first end of each crosspiece 5, sign 6, bar or blade between two legs 8 of a first amount 4, the fixing of each crosspiece 5, sign 6, bar or blade on the first upright 4, each crosspiece 5, sign 6, bar or blade being fixed at a different height on the first upright 4 ; inserting a second end of each crosspiece 5, sign 6, bar or blade between two legs 8 of a second amount 4, the fixing of each crosspiece 5, sign 6, bar or blade on the second upright 4, each crosspiece 5,sign 6, bar or blade being fixed at a different height on the second upright 4. The inventive method further comprises the other steps defined in the appended claim 1.

[0066] Then, a simple closure 14 and a rebated closure 15 can be put into position by snapping onto the tabs 9 of the uprights 4. The closures 14, 15 ensure the closure of the uprights to limit access to the screws and reinforcing the security provided by the gate 1, while providing a pleasant visual appearance.

[0067] Optionally, caps can be added to the ends of the closures and / or uprights, for example by gluing.

[0068] When the gate 1 includes a second opening 2, this is mounted in the same way, except that its two uprights 4 are each closed by a simple closure 4.

[0069] Once the two openings 2 are mounted, they can be assembled to the posts 3. In the case where the openings 2 are intended to be pivotable relative to the posts 3, the elements for creating a hinge connection are provided to the user. A stop 16, intended to be fixed in the ground, can also be provided. The openings 2, when the gate 1 is closed, come into contact against the stop 16. The actuating mechanism can be put in place, for example between each post and the intermediate crosspiece 5 reinforced by the bar 13 of each opening 2.

[0070] Thanks to the 2-leaf kit offered, the user can adapt the length of the leaves themselves to suit an existing configuration. The elements of the 2-leaf can all be delivered in standard dimensions, so manufacturing costs are reduced. The user simply follows the assembly instructions to obtain a gate adapted to their needs.

[0071] According to the embodiment presented, the number of elements to be cut to the correct length is limited to the three crosspieces 5 and the two filling panels 6 per opening, which can be easily done by the user.

[0072] Similarly, the height of the uprights 4 can also be adapted to suit requirements by also proposing to cut them to a specific height. In this case, the height of the infill panels 6 is also adapted by a cutting step. The instructions for this purpose are included in the instructions.

[0073] A variation of the portal is illustrated on the figure 8 . According to this variant, the portal 20 is sliding and comprises two openings 2 similar to those described above, except that they share a crosspiece 21 common lower, and a crosspiece 22common upper, extending along the length of the two openings 2 and beyond. The lower crosspiece 22 is then provided with wheels 23 to ensure the sliding of the gate 20 for example by cooperating with a rail fixed to the ground. The instructions then provide the calculation to be carried out to obtain the appropriate length for the upper crosspiece 21, the lower crosspiece 22 and each of the intermediate crosspieces 5, from the distance L measured between two posts between which the openings extend when the gate 20 is closed.
