FR2770867A1 - Gate with integrated support frame - Google Patents

Abstract

The gate comprises uprights and cross members each being composed of a shell shaped casing (9) made from an extruded plastic which does not contribute to the mechanical strength of the gate. There is a tubular frame component (7) completely integrated in the casing and connected to other frame components by fixing nuts to form a support frame (6).

Description

 The present invention relates to barriers consisting of at least uprights and crosspieces and which are put in place to control a crossing, an access between two delimited areas, at least one of which may be part of a reserved area.

 The invention relates, more specifically, to the barriers used or organized as elements of gates comprising at least one leaf or leaf, generally but not exclusively, adapted to pivot on a vertical axis with respect to a fixed support structure.

 The barriers and gate elements of the above type have been the subject of a large number of constructive proposals relating to a manufacturing technique, known as traditional.

 These are mainly barriers or gates based on metal elements, linked together by mechanical assembly or by welding, or barriers or gate elements based on pieces of wood which can be nested and linked between them or attached by removable fixing means.

 Such traditional manufacturing proposals make it possible to offer a large number of constructive modes, combining resistance characteristics, as well as varied aesthetic presentations. Such construction methods are, however, of a high production cost, even if they are the subject of a production in small or medium series.

 This is the reason why a different constructive method was then proposed, in an attempt to overcome this problem of cost price which is prohibitive.

 There have appeared constructive proposals involving a support frame, generally metallic, on which are adapted the accessories for maneuvering and locking and on which is fitted a covering made of plastic elements, generally extruded, which are mounted applied on such a frame.

 As a general rule, the plastic elements are based on polyvinyl chloride and affect the shapes of profiles obtained by extrusion with regard to the covering of uprights, crosspieces, or even the formation of bars.

 This constructive proposal cannot be considered to offer a satisfactory solution on many aspects.

 First of all, the adaptation of the covering applied to the frame is generally carried out on a single face of the latter, so that an unsightly appearance remains on the other face, whether the latter is external or inside the privileged area that the barrier or gate controls.

 To remedy this drawback, it has been proposed to adapt, on the second face of the barrier or of the gate, a kind of secondary covering aiming to conceal the frame. Such a proposal does not solve the problem of the lack of aesthetics and involves designing a specific covering for each portal realization.

 Given the requirement to apply a covering, in particular based on plastic, to a load-bearing frame, it is generally observed that the ability offered by plastic to produce parts of various shapes is not used profit and that the aesthetic character that could be expected is not achieved.

 The object of the invention is, precisely, to remedy the drawbacks noted above by proposing a new construction of a barrier, of the type comprising uprights and crosspieces and forming a frame which is completely integrated inside the 'a covering made of a material of relatively low resistance compared to that of the supporting frame.

 By the above means, it becomes possible to produce barriers or portal elements offering a varied aesthetic appearance and having a presentation of homogeneous and symmetrical character never before achieved to date.

 Another object of the invention is to propose technical means which make it possible, if necessary, to carry out a rapid undressing to gain access to the supporting frame or, again, to bring about either a modification of the aesthetic appearance from of certain constituent elements of the covering or a restoration following disorders, destruction or partial or total deterioration.

To achieve the above objective, the barrier with integrated reinforcement, of the type comprising uprights and at least sleepers, is characterized in that each upright or each sleeper is composed
- a shell-shaped covering envelope, made in a
material not contributing to the mechanical strength of the whole
the barrier,
- and a reinforcement element fully integrated into the envelope and linked
to the other reinforcing elements by fixing nuts to form,
with these, a load-bearing frame.

 The invention also relates to the constitution of a portal element, such as an opening or leaf, applying the above provisions.

 Various other characteristics will emerge from the description given below with reference to the appended drawings which show, by way of nonlimiting examples, embodiments of the subject of the invention.

 Fig. 13 is a sectional elevation, similar to FIG. 4, but illustrating an alternative embodiment.

 Fig. 14 is a cross-sectional view of another embodiment of a component of the object of the invention.

 Fig. 1 shows a barrier according to the invention, illustrated by way of nonlimiting example, in a preferred application to the constitution of a portal designated as a whole by the reference 1. Such a portal also comprises, preferably on the basis illustrated in fig. 1, two opening elements 2a and 2b or leaves which are carried, with the possibility of rotation along two vertical axes, by two structures 3a and 3b of the post type.

 I1 must be remembered that the portal 1 could comprise only one opening or leaf, 2a or 2b indifferently, or, again, offer a different composition. Similarly, the object of the invention also applies to a barrier which does not automatically have the vocation of a gate 1 and which constitutes, for example, a fixed delimitation between two zones, at least one of which is reserved access.

 A barrier according to the invention or a portal element, such as 2a, is composed, essentially, of uprights 4 and crosspieces 5 which are linked together, so as to form a resistant unitary assembly.

 The object of the invention is precisely the construction of the uprights 4 and crosspieces 5 and involves a supporting frame 6 which consists of frame elements 7 linked together by nuts 8 which can allow temporary or permanent fixing. The reinforcing elements 7 are constituted by closed sections, of the metallic type and, for example but not exclusively, affecting a polygonal cross section and, more generally, rectangular, as illustrated in FIG. 2. The frame 6 is fully included and integrated into a covering 9 made of plastic and, advantageously, constituted by envelopes having, in the embodiment according to FIG. 2, each in the form of a tubular profile 10 delimiting at least one closed box 11 into which can be introduced, preferably by tight fitting, a reinforcing element, such as 7.

 Within the meaning of the invention, it must be considered that each upright and each cross member is produced in a similar manner, possibly using tubular sections 10 of different shapes and sections, depending on whether they are intended to constitute uprights or sleepers, the only requirement to be met in all cases is that of offering a closed box 11 capable of receiving, by fitting, the corresponding reinforcing profile 7.

 Fig. 3 shows that the reinforcement elements 7, constituting the reinforcement 6 as an upright element or a cross member, are linked together, for two contiguous, by a nut 8 which comprises, for example, a central part 12 extended by one or two or three end pieces 13, depending on whether the nut must constitute a corner or "T" connection piece. The end pieces 13 are provided to ensure an interlocking with the end parts of the elements 7, the ends of which are in cross section. It must, of course, be considered that a miter cut could occur in a similar manner.

 The connection, between each end piece 13 and the corresponding reinforcing element 7, can be ensured by means of fixing members 14, of the screw or rivet type, these fixing means being able, if necessary also, to be replaced. by an adhesive-based bond.

 The tubular profiles 10, constituting the covering 9, are fitted onto the reinforcing elements 7 on which they can be secured by means of fixing members, such as 15, for example constituted by screws or the like.

 Fig. 3 shows that the nut 8 illustrated can be provided with an accessory 16 intended to promote the pivoting mounting relative to a post, such as 3a, such an accessory 16 which can be formed in the form of a remote pivot head. An assembly in the axis of the reinforcing element constituting the upright can, of course, be envisaged.

 The various barrier elements, constituting the uprights 4 and the crosspieces 5, can be joined together, in a traditional manner, by a panel 17 which can be assembled to the uprights and crosspieces, by means of interlocking profiles 18, such as illustrated in fig. 2. An assembly of the same order can occur when the barrier according to the invention is completed by elements of bars of the type of that represented by the reference 19 in FIG. 1.

 As is apparent from the above, the technical means according to the invention, consisting in combining a supporting frame based on elements 7, preferably but not exclusively tubular, joined together in a possibly removable manner, and with a decorative covering based on extruded plastic profiles, make it possible to produce a barrier element offering a symmetrical character and of the same aesthetic appearance on its two faces, while offering a possibility of adaptation, fixing, or even pivoting in the case of gates , with respect to a fixed structure, such as 3a.

 The profiles 18 can be of various shapes and constitutions, without coming directly within the scope of the invention, since they are able to establish an adaptation connection between the uprights and / or crosspieces and, either a solid panel, i.e. bars 19.

 Fig. 4 shows that the means used, as described above, have the possibility of adaptation in the context of specific applications, such as those of a portal illustrated in FIG. 1.

 Indeed, the reinforcing element 7, constituting an upright 4 of an opening or leaf, such as 2b, can advantageously support a lock block 20 disposed internally at the profile 10, so that it can be controlled for the erasure of a latch bolt 21 by a handle 22.

 In such an example of application, it is advantageous to provide the corresponding section 10 with a lining 23 ensuring the protection and guiding of the bolt 21 in the window part 24 formed in the section 10 to allow passage to the bolt 21.

Similarly, the profile 10 of the upright 4 of the opening 2a located in opposition can then be furnished with a strike head 25 assuming the same function with respect to a window 26 formed in the profile 10.

 As an example, it can be noted, from fig. 4, that the lining 23 can be used to also ensure the connection on the profile 10 of a joint cover or flap 27 whose function, as it emerges from FIG. 1, is to perfect the aesthetics in the case of application to a gate with double leaves, as illustrated in FIG. 1.

 Fig. 5 shows an alternative embodiment of the supporting frame 6. According to this example, each frame member 7, constituting an upright or a cross member, is made up, as appears more clearly in FIG. 6, of a tubular profile 30 having, preferably but not exclusively, a polygonal cross section and, advantageously, rectangular. The profile 30 comprises, on a part of its outer surface, and preferably in relation to one of the transverse sides 31, a longitudinal slide 32 with a constant profile, of the "T" type. The slide 32 can be produced in several different ways but, that preferred within the meaning of the invention, consists in delimiting it by means of two flanges 33 oriented in the direction of one another, extending parallel to the transverse side 31.

 It is advantageous, for reasons which emerge from the following, to also provide, on the second transverse face 34 of the tubular profile 30, a second "T" slide 35 which can meet the same constructive characteristics as the slide 32 or, again, have different dimensions and / or conformation.

 The tubular profile 30 is also made to comprise, on a part of its internal surface, and preferably on that corresponding to one of the transverse sides 31 or 34, a projecting molding 36 delimiting a groove 37.

 The slides 32 and 35, as well as the molding 36, are designed to assume specific functions which emerge from the following, but also to constitute stiffening elements contributing to impart good mechanical resistance to the tubular profile 30.

 Two tubular sections 30, intended to constitute, partly an upright element and partly a cross member, are linked together by a nut 8 as said previously, such a nut being formed, in the embodiment according to FIGS . 5 and 6, by a tubular segment 40 whose overall width I and whose height h are chosen so as to allow engagement inside a tubular profile 30. Due to the presence of the molding 36, the tubular segment 40 has, from a common edge, such as 41, notches 42 the cross section of which is equal, to the nearest clearance by excess, to that of the molding 36.

 Preferably, the tubular segment 40 has a polygonal, and more particularly rectangular, section, comprising two transverse faces 43 and two longitudinal faces 44. The height h corresponds to that of the tubular profile 30, as well as the width I, so as to allow soft glide engagement. In this embodiment, the notches 42 are formed in the transverse walls 43 from the common edge 41.

 One of the transverse walls 43 carries, on its outer surface, a pair of tongues 45 which are produced so as to allow engagement and cooperation inside the slide 32 or 35. As previously, the segment 40 comprises, on the inner surface of the second wall 43, a projecting molding 46, delimiting a groove 47 open longitudinally, that is to say in the height direction h.

 The nut 8 is associated with temporary fixing means 50, 50l, or even 502, which are implemented as required.

 The nut 8 is, for example, threaded, by its pair of tabs 45, in the direction of the arrow f, into the slide 32 of the profile 30 oriented vertically on the base of FIG. 6, to contribute to forming an upright of the frame 6. In the position required for the segment 40, the profile 30 is pierced transversely with holes 51 which make it possible to engage, through the transverse walls 31 and 34, a screw 50 fixing which is arranged in the notches 42. The profile 30, intended to constitute a cross member of the frame 6, is threaded on the segment 40 so that the screw 50 is presented facing the groove 37 in which it carries out, by self-tapping for example, its screwing to tighten the cross section profile 30 against the upright section 30.

 It may be envisaged to perfect the fixing by initially securing the tubular segment 40 in the slide 32, for example by means of an S0 screw, engaged by a hole 52 through the wall 43, to be screwed into a tapped hole counterpart 53 (fig. 7) presented by the second wall 43. In this way, the screw 50l ensures, by compression effect on the outer face of the transverse wall 31, immobilization by pressurization between the tongues 45 and the flanges 33.

 The fixing could also take place by a screw, such as 50l, which would be engaged through a continuity solution 54 practiced over the entire height of the wall 43 carrying the tongues 45, so as to confer on this wall a faculty of expansion in the direction of the arrows f2, ensuring the locking of the tongues 45 inside the slide 32 after assembly of the tubular segment 40 on the tubular section 30 of the upright.

 It can be envisaged to perfect the connection between two tubular sections 30 by immobilizing the cross section section on the segment 40 by means of a transverse screw of the type of that bearing the reference 502.

 The frame 6, constructed on the basis of the elements described above, can then receive a covering 9 in the form of a shell which is, however, advantageously constituted by shells 60 having internal edges 61 capable of being fitted elastically behind the edges 33 of the slides 32. Such an example is illustrated in FIG. 8 showing an embodiment of symmetrical half-shells 60, with respect to a reference plane P-P 'corresponding to that of the frame. The half-shells 60 are shaped to dress the two faces of the frame while allowing between them, by their conformation, two extreme intervals 62 which are intended to allow the fitting, either of a panel, such as 17, or bars, such as 19.

 Fig. 9 shows that the half-shells 60 can then be completed by an additional profile 63, when it is necessary to fill one of the intervals 62. The profile 63 also has flanges 64 intended to be snapped behind complementary projections 65 presented by the half-shells 60.

 Fig. 10 shows that one in two half-shells, such as that bearing the reference 601, can be shaped locally so that, after fitting onto the tubular element, it completes and fills one of the intervals 62 by registering in the peripheral profile of the first half-shell 60.

 Fig. 11 shows that two half-shells 601 can be put in place to completely cover the tubular profile 30 constituting the carrying frame which is then fully integrated and hidden inside the covering 9.

 Fig. 12 shows a variant in which two half-shells 602 and 603 are adapted on a tubular profile 30, each being fitted into a slide 32. In such an example, the half-shells are put in place by being fitted on both sides. other of the profile 30. The conformation of the half-shells involves cooperation between serrated wings 65 presented by one with notched areas 66 formed by the other.

 This embodiment, involving, for the half-shell 603, a resistant boxed shape, makes it possible to produce a profiled covering 9, analogous, by shape recognition only, to an airplane wing profile which would have an edge d attack 66 and a trailing edge 67. In the example illustrated, such a profile is of the symmetrical biconvex type, but it must of course be remembered that a different conformation could be envisaged.

 It should be noted that the particular shape of the tubular sections 30 and that of the half-shells make it possible to produce a covering 9 completely enveloping the frame 6 which is fully integrated. Such an embodiment is advantageous because it offers a large choice of possible embodiment of the aesthetic form of the covering and also allows easy assembly and disassembly of all or part of the covering to allow any necessary change. .

 Fig. 13 shows another embodiment of the half-shells 602 and 603, with regard to the uprights 4 facing a portal with two leaves.

In such a case, the half-shells 602 and 603 can be provided with a lining 68 intended to guide the bolt 21 and to constitute the keeper 25, respectively.

 Fig. 14 illustrates another alternative embodiment of the profile 30 no longer formed in a tubular form, but in an open form comprising a core 70 bordered by two wings 71 delimiting, by flanges 72, the slides 32. In such an example, it is also possible to link the core 70 to one of the wings 71 by a molding, such as 36.

 The invention is not limited to the examples described and shown since various modifications can be made thereto without departing from its scope.
