Abstract
Description
[0001] This disclosure relates to a portal structure. technical field
[0002] This disclosure relates to the field of locking devices intended specifically for outdoor use to open and close a passage in a fence, wall, etc. It applies to both sliding and swing gates. A gate as described in this disclosure is advantageously made of metal, but it could also be made of a synthetic material. Previous technique
[0003] It is known to construct a gate by assembling various elements that make up the gate. In the case of a metal construction, it is common to assemble the components by welding. FR 3 106 844 A3 shows a gate according to the closest prior art.
[0004] The resulting gates are time-consuming to manufacture due to the numerous welding operations involved, as well as the cutting and assembly of the profiles. Furthermore, the finished gate is usually impossible to disassemble. Summary
[0005] This disclosure aims to improve the situation. Its purpose is to provide a gate structure that is easy and quick to assemble. Ideally, the gate will be demountable to facilitate maintenance and repairs.
[0006] A portal is proposed that includes: a first crossbar, a second crossbar, and at least two connecting bars each extending from the first crossbar to the second crossbar and having a first end and a second end.
[0007] According to this disclosure, the two crossbeams and the aforementioned connecting bars are tubular components. the first end of each of said connecting bars is housed inside the first cross member which has an opening adapted to allow the introduction of said first end into the first cross member, the second end of each of said connecting bars is housed inside the second cross member which has an opening adapted to allow the introduction of said second end into the second cross member, and a screw passes through each time the first cross member, a connecting bar and the second cross member, a screw head bearing against an outer wall of the first cross member while a nut cooperating with the screw bears against an outer wall of the second cross member.
[0008] The features described in the following paragraphs may optionally be implemented, independently of each other or in combination with each other: Each cross member has a rectangular cross-section with two short sides and two long sides; in this variant, it may also be provided that said connecting bars pass through one face of the first cross member and one face of the second cross member, each corresponding to a short side, and / or that each cross member has openings on one face corresponding to a short side, the contour of which is adapted to the cross-section of the connecting bars, and on its opposite face, also corresponding to a short side, holes adapted for the passage of the screw and arranged opposite each opening, the surface area of a hole being less than the surface area of the opening opposite it; said connecting bars are tubes with a circular cross-section; at least one screw has a shank that is at least partially threaded, a screw head, and between the head and the shank a non-circular cross-section area, for example, a square one; the nut is a pin nut;The ends of the crossbeams are each closed with a cap; the crossbeams and connecting bars are made of galvanized steel. Brief description of the drawings
[0009] Other features, details, and advantages will become apparent upon reading the detailed description below and analyzing the attached drawings, on which: Fig. 1 [ Fig. 1 ] shows a portal in front view according to one embodiment. Fig. 2 [ Fig. 2 ] shows the portal of the figure 1 , without plugs, side view. Fig. 3 [ Fig. 3 ] shows a cross-sectional view along section line III-III of the figure 1 . Description of the implementation methods
[0010] Reference is now being made to the figure 1 which represents one form of realization of a portal according to this disclosure.
[0011] The gate shown in the drawing comprises an upper rail 2, a lower rail 4, and connecting bars 6 linking the upper rail 2 and the lower rail 4 together. These three elements are assembled by bolting, and as can be seen in the figure 1 For each connecting bar 6 there is a screw 8, of which we can recognize a screw head 82 and a screw shank end 84. A nut 10 cooperates with the screw 8. We also note at each end of the two cross members the presence of a plug 12.
[0012] The proposed orientation of the gate is as it would be in its normal operating position. The crossbars then extend horizontally and the connecting bars vertically. This top / bottom orientation is thus used throughout this description, corresponding to the designation "upper crossbar" for the crossbar with reference number 2 and "lower crossbar" for the crossbar with reference number 4.
[0013] The shapes illustrated in the drawing are basic forms used to explain a gate structure according to this disclosure. However, a person skilled in the art will be able to adapt these shapes to achieve an aesthetic effect, which is important in gate construction. For example, streamlined shapes are described for the crossbars, but curved shapes could also be used, particularly for the top rail. The cross-sections of each tube can vary depending on the desired aesthetic effect.
[0014] It is proposed here to have an upper cross member 2 and a lower cross member 4, each made from the same rectangular cross-section profile ( figures 2 And 3 ). There figure 2This is a side view (without the end caps 12) showing the shape of the profile used here. It is a rectangular profile. With the proposed orientation, the shorter sides of the crossbars correspond to the thickness of the gate and are horizontal, while the longer sides extend vertically along the height of the gate and lie in a vertical plane. It is assumed that each crossbar has a straight shape, thus defining a horizontal longitudinal axis for each.
[0015] The connecting bars 6 extend vertically. They are circular tubular bars. Each one has a vertical longitudinal axis.
[0016] The connecting bars 6, the upper crossbar 2 and the lower crossbar 4 are, for example, made of galvanized steel. However, other materials, metallic (aluminum-based alloy for example) or non-metallic (synthetic material such as PVC) could be used.
[0017] The connecting bars 6 each have an upper end and a lower end. Each upper end of a connecting bar 6 is fixed into the upper cross member 2, and each lower end of a connecting bar 6 is fixed into the lower cross member 4. To this end, the lower wall (corresponding to a short side) of the upper cross member 2 and the upper wall of the lower cross member 4 are each provided with openings 14 of a diameter adapted to the outside diameter of the connecting bars 6 (which are assumed here to be all similar; however, here too, for aesthetic reasons, the bars could be non-circular, with different cross-sections and / or diameters). The ends of the connecting bars 6 are inserted through an opening 14 until the inserted end abuts against the wall of the cross member opposite the wall in which the opening is located.The openings 14 are, for example, made in such a way that the horizontal longitudinal axes of the crossbeams and the vertical longitudinal axes of the connecting bars 6 are all in the same (vertical) plane. The connecting bars 6 are, for example, arranged between the crossbeams with a regular spacing.
[0018] To secure the connecting bars 6, the upper crossbar 2, and the lower crossbar 4, the assembly is bolted together. Screws 8 and nuts 10 are used for this purpose. Each screw 8 passes through the upper crossbar 2, a connecting bar 6, and the lower crossbar 4. For this purpose, a hole 16 is provided for each screw 8 in the upper wall of the upper crossbar 2 and a hole 18 in the lower wall of the lower crossbar 4. Here, a square hole 16 and a round hole 18 are planned. Note that the surface area of the holes (16 or 18) is smaller than that of the openings 14: this allows the ends of the connecting bars 6 to fit snugly against the crossbars.
[0019] Indeed, it is advantageously provided that each screw 8, between its screw head 82 and its shank 84, has a zone 86 with a non-circular, square cross-section in the embodiment shown here. Each upper hole 16 is sized to fit each zone 86 of a screw 8. At the lower level, the hole 18 allows the passage of the screw shank 84. The screw shank 84 is threaded to receive a nut 10. Those skilled in the art will note that the screw shank 84 does not require threading along its entire length. The threaded portion of the screw shank 84 then cooperates with the nut 10 so that the latter can bear against the underside of the lower cross member 4. The nut 10 is, for example, a pin nut. It is possible to obtain a tight fit, and a special tool is required for disassembly (which limits the risk of someone else loosening a nut).
[0020] After assembly, the portion of the screw shank protruding from the nut can be cut off. Plugs 12 can also be fitted. These are, for example, plugs made of synthetic material. These plugs 12 have, for example, a mushroom shape with a base of a shape and dimensions suitable for a secure fit with at least slight tightening in one end of a cross member, and a head sized to cover the entire cross member section.
[0021] The plan here is to mount all the connecting bars in the same way. It would be possible to mount only some of the connecting bars in this manner to ensure the gate's mechanical rigidity, while attaching other bars for aesthetic purposes differently. However, for the gate's rigidity, it is preferable to have all the bars recessed at each end into the two crossbars. Industrial application
[0022] These technical solutions can be applied, in particular, to the manufacture of a gate. This structure allows for rapid assembly while providing the gate with high rigidity.
[0023] The parts can be treated before assembly. Furthermore, the gate can be assembled on site. This greatly simplifies transport and reduces the handling of large parts.
[0024] This disclosure is not limited to the example embodiment described and the variants mentioned above, only by way of example, but encompasses all the variants that a person skilled in the art may consider within the framework of the protection sought, according to the attached claims.
