Description

[0001] The present invention relates to the technical field of gates and more particularly to gates comprising at least one leaf with a plurality of leaves hinged relative to each other. Indication of prior art

[0002] Gates are known comprising at least one leaf with a plurality of leaves hinged to each other. They can be used when the passage to be able to be closed by the gate is large, for example for an entrance to an agricultural or industrial farm or a residential plot and the available space does not allow the use of a single leaf. The passage in question can then have a dimension of between 4 and 16 meters. One solution is to use a sliding type gate, but this is only possible if there is sufficient clearance in the sliding axis to accommodate the gate in the open position. Another option is to divide the gate leaves into at least two smaller leaves whose total length corresponds to the opening distance to be able to be closed by the gate.The leaves are hinged to each other and can be folded down on top of each other to reduce their space requirement when open. The leaves are hinged to each other. Most often, they are hinged in rotation, for example by means of hinges, hinges or pintles.

[0003] It is preferable to fold the leaves on the rear face of the gate because the front face is often decorated with flourishes for aesthetic reasons and does not allow the leaves to be folded.

[0004] A single leaf can be configured to resist deformation. The leaf is framed by a frame (the peripheral edge(s) that delimit the outer edge of the leaf) whose thickness is calculated accordingly. On the other hand, when using a plurality of hinged leaves in rotation, at the time of opening or closing, the two leaves can form an angle close to 90°. In this case, the first leaf (closest to the pillar) is subjected to very high stresses and can undergo significant warping, making it unusable thereafter.

[0005] It has already been proposed, for example in GB-A-680156, a two-leaf gate which is said to be adapted to avoid warping of the leaves. The gate described in this document comprises at least one post, at least one leaf, said leaf being provided with two leaves hinged to each other by hinge means between the leaves, means allowing rotation of the leaf relative to the post, in which the first leaf, located closest to the post, comprises a leaf frame defining a plane, a bar which connects the bottom of the frame near the post to the top of the frame near the opposite end of the leaf, along a diagonal of the frame. The bar is a tension bar. Such a leaf, however, does not provide satisfactory results and suffers very significant warping, in particular if the second leaf has a length greater than or equal to that of the first leaf.Also known from DE-U1-2020 201 00880 is a folding swing gate that comprises two leaves, a supporting leaf fixed to a pillar and a driven leaf hinged to the first. The structure is based on an integrated folding mechanism, using hinges, a telescopic rod and pivoting connecting elements, which allow coordinated movement of the two leaves. A system of adjustable screws adjusts the positions of the leaves along two axes (X and Y), ensuring precise opening and closing. When opening, the mechanism extends both leaves to reach their maximum length. When closing, the driven leaf folds against the supporting leaf, thus reducing the space required. The design uses pivoting triangular plates and "hockey stick" elements to connect and coordinate the movements. An adjustable telescopic rod facilitates initial adjustment and compensates for dimensional variations.The gate is designed to pivot up to 180° between the leaves, allowing for a significant reduction in the footprint in the open position. The main advantage is its compatibility with tight spaces and its optimized operation even in difficult winter conditions. Finally, document RU-U1-197662 describes folding swing gates that open outwards. These gates have two hinged leaves that, in the open position, fold at an obtuse angle compared to their closed position, thus avoiding occupying the area between the posts. Each leaf consists of two parts hinged together, allowing the outer section to fold alongside the inner section. A three-joint mechanism connects the two parts, ensuring smooth folding of the leaves when they open.The gate leaves are attached to the posts by special hinges, and motors integrated into niches in the posts operate their movement. This design minimizes the footprint in front of the gate, while allowing an opening of up to 180°. The objective of the last two documents is not to prevent warping, but to reduce the gate's footprint.

[0006] It would therefore be desirable to have a gate that could open and close a large passage without being subject to warping. Statement of the invention

[0007] This problem is solved according to the invention with a gate comprising at least one post, at least one leaf, said leaf being provided with a plurality of leaves articulated relative to each other by articulation means between the leaves, means allowing the rotation of the leaf relative to the post, in which the first leaf, located closest to the post, comprises a leaf frame defining a plane, called the plane of the leaf frame, a first bar which connects the bottom of the frame near the post to the top of the frame near the opposite end of the leaf, along a diagonal of the frame. The gate according to the invention is particularly characterized by the fact that the first bar is pushing, and a second bar which is pulling connects the top of the frame near the post to the bottom of the frame near the opposite end of the leaf, along another diagonal of the frame.The inventor was able to test the gate according to the invention and was able to demonstrate that even with very long leaves, the leaves do not undergo any deformation and in particular, no warping, even if they are left open at 90° to each other.

[0008] It is believed that both the push and pull bars cooperate to provide this result.

[0009] According to an advantageous embodiment, the first push bar is attached to the bottom of the frame near the post by means of a spacer, offsetting the end of the push bar relative to the plane of the frame. The offset of the end of the push bar relative to the plane of the frame allows for increased strength.

[0010] Advantageously, the second bar, which is the pull bar, is attached to the top of the frame near the post by means of a spacer, offsetting the end of the pull bar relative to the frame plane. Offsetting the end of the pull bar relative to the frame plane also allows for increased strength. The simultaneous offset of the ends of the push and pull bars makes the gate extremely resistant to warping.

[0011] Advantageously, in both cases, the spacer has a length greater than 1 cm and preferably between 10 cm and 50 cm. The latter value range provides the most interesting results.

[0012] Advantageously, in both cases, the spacer is in the form of an angle iron so as to provide significant resistance and very little deformation under stress.

[0013] According to another embodiment, the push bar and / or the pull bar and the plane of the leaf frame form an angle α of between 1 and 20°, preferably of between 3 and 10° and particularly preferably of between 4 and 8°. The latter range of angles provides the most interesting results.

[0014] According to another embodiment, at least one of the two bars is provided with a device for adjusting the length of the bar. This may be, for example, a double-threaded female sleeve placed between two halves of the bar in question, the ends of the bars intended to enter the sleeve are also threaded. This embodiment allows adjustment of the thrust or the pull, depending on whether the device for adjusting the length of the bar is arranged on the pushing bar or on the pulling bar. Of course, both the pushing bar and the pulling bar can be equipped with such a device.

[0015] According to another embodiment, at least one of the leaves comprises a panel, preferably a screening panel, arranged in the plane of the leaf frame. Such panels, in particular screening panels, provide wind resistance so that the structure of the gate is subjected to high stresses. However, thanks to the present invention, despite these stresses, the gate does not undergo deformation or warping.

[0016] Blackout panels can be made of wood, metal, or plastic. Preferably, a material with a reasonable density should be used to avoid creating too much weight on the leaves. For example, for wood, a type of wood with a specific gravity (air-dry wood) of less than 3.0, preferably less than 2.0, is preferred. A low density for wood is sometimes associated with durability issues. Thus, a type of wood with a specific gravity (air-dry wood) greater than 0.5 is preferred. Padouk (Pterocarpus soyauxii) or afrormosia (Pericopsis elata) are particularly suitable due to their durability combined with a reasonable density (0.85 and 0.74 respectively). A metal blackout panel can also be used. In the latter case, aluminum is preferred.

[0017] According to another embodiment, a retaining element attached to the first leaf retains the push bar at a predetermined distance from the plane of the leaf. The retaining element can be attached to the first leaf via a screening panel or on a reinforcement bar arranged on the leaf. This embodiment makes it possible to prevent the deformation of the bar, thus canceling out the traction or thrust exerted, even in the event of very high stresses. In particular, it is observed that if the second leaf is particularly heavy, the bar can take on an arched shape (banana shape). Such a retaining element avoids this inconvenience. Preferably, the retaining element is arranged along the push bar, at a distance from one of its ends of between 1 / 8 and 7 / 8 of its length, particularly preferably, of between 1 / 4 and 3 / 4 of its length.It is not necessary to keep the tie rod at a predetermined distance from the plane of the leaf. Indeed, the tie rod nature of this bar prevents the risk of bending.

[0018] According to a variant of this embodiment, the push bar is retained at a predetermined distance from the plane of the leaf frame by several retaining elements. This embodiment retains the advantages stated above while facilitating assembly.

[0019] The gate according to the invention can be used alone or in combination with a similar or different gate. Brief description of the figures

[0020] The invention will now be described by means of figures which have no other purpose than to illustrate the present invention. These figures schematically represent: Fig. 1 A top view of a portal according to the invention; Fig. 2 A view of the rear of the gate of the Fig. 1 . Fig. 3A top view of another portal according to the invention;

[0021] We represented at the Fig. 1 a portal 1 seen from above and at the Fig. 2, the same gate seen from the rear. This gate comprises a post or pillar 11 and a leaf 12. The leaf shown here comprises two leaves 131 and 132. The leaves 131 and 132 are articulated relative to each other by means of articulation means 14, for example hinges, hinges or other means making it possible to create a pivot connection. The gate 1 also comprises means 15 allowing the rotation of the leaf 12 relative to the post 11. These may be, for example, hinges, hinges or any other means allowing a pivot connection to be made between the post 11 and the first leaf 131 of the leaf 12. The first leaf 131 which is closest to the post 11 comprises a frame 16. Here the leaves 131 and 132 are shown, each equipped with a concealing panel 17. It is understood that the concealing panel may be present on one or the other of the leaves or on both leaves.We see a first bar 18 which connects the bottom of the frame 16 near the post 11 to the top of the frame 16 near the opposite end of the leaf 131, along a diagonal of the frame 16. This bar is pushing. A second bar 19, pulling this one, connects the top of the frame 16 near the post 11 to the bottom of the frame 16 near the opposite end of the leaf 131, along another diagonal of the frame 16. The two bars 18 and 19 cooperate and effectively prevent any warping of the first leaf 131 under the weight of the second leaf 132. In this case, the two leaves 131 and 132 each have a length of 8 m. No warping was observed, even when the second leaf 132 forms an angle of 90° with respect to the first leaf 131.

[0022] Here we have shown the first pushing bar 18 attached to the bottom of the frame 16 near the post 11 by means of a spacer 20, offsetting the end of the pushing bar 18 relative to the plane of the frame 16.

[0023] It is possible to provide that the bar, 19 for example, is cut in two, for example at a third of its length. The two internal ends are each threaded. A double-threaded sleeve connects the two internal ends of the bar 18 or 19. This allows adjustment of the thrust or traction, depending on whether the device for adjusting the length of the bar 18 or 19 is arranged on the pushing bar 18 or on the pulling bar 19.

[0024] We also see on the Fig. 1, a retaining element 21 attached to the panel 17 of the leaf 131. This retaining element 21 retains the push bar 18 at a predetermined distance from the plane of the leaf frame. The retaining element is arranged along the push bar 18, at a distance from one of its ends of between 1 / 8 and 7 / 8 of its length, preferably of between 1 / 4 and 3 / 4 of its length.

[0025] There Fig. 3 represents a portal similar to that of the Fig. 1 The difference is that the push bar is held at a predetermined distance from the plane of the leaf frame by two retaining elements 21. We see on the Fig. 3 that these are off-center in relation to the leaf and in relation to the bar. List of drawing references :
