Abstract
Description
[0001] SHATTERPROOF GATE.
[0002] DESCRIPTION
[0003] The invention relates to a shatterproof gate designed to withstand the frontal impact of a vehicle.
[0004] Shatterproof gates configured to obtain the opening and closing of a gap through a fence by means of the translation of a movable wall and designed to withstand the frontal impact of a vehicle are currently known.
[0005] A similar known type of shatterproof gate comprises:
[0006] - a substantially rectangular movable wall;
[0007] - sliding means configured to allow the translation of such a movable wall along its longitudinal extension axis and orthogonally to the ground plane;
[0008] - a support structure provided with a base configured to be fixed to the ground and with at least a first gap for the passage of the movable wall through such a support structure;
[0009] - a reinforcing structure provided with a base configured to be fixed to the ground and with at least a second gap adapted to accommodate one end of the movable wall when the aforesaid shatterproof gate is in the closed position.
[0010] A similar shatterproof gate, although known and appreciated, has some important limitations.
[0011] In particular, a first limitation is related to the difficulty of transporting and installing such a shatterproof gate due to its weight.
[0012] A second limitation is related to the need to oversize the movable wall in terms of thickness to prevent a frontal impact with a vehicle from causing a flexural deformation such as to cause such a movable wall to break.
[0013] The task of the present invention is to develop a shatterproof gate capable of obviating the aforementioned drawbacks and limitations of the prior art.
[0014] In particular, it is the aim of the present invention to make a shatterproof gate which is lighter and more transportable with respect to a similar shatterproof gate of known type with the same resistance to a frontal impact with a vehicle. Further, an aim of the invention is to develop a shatterproof gate whose resistance to flexural deformation of the movable wall associated with a frontal impact with a vehicle is greater with respect to a similar shatterproof gate of known type.
[0015] The above-mentioned task and objects are achieved by a shatterproof gate according to claim 1 .
[0016] Further characteristics of the shatterproof gate according to claim 1 are described in the dependent claims.
[0017] The task and the aforesaid aims, together with the advantages that will be mentioned hereinafter, are indicated by the description of an embodiment of the invention, which is given by way of non-limiting example with reference to the attached drawings, where:
[0018] - figure 1 represents a perspective view of a shatterproof gate according to the invention;
[0019] - figure 2 represents a top view of figure 1 ;
[0020] - figure 3 represents a perspective view of a first element of the shatterproof gate of figure 1 ;
[0021] - figure 4 represents a sectional front view of figure 3;
[0022] - figure 5 represents a perspective view of a second element of the shatterproof gate of figure 1 ;
[0023] - figure 6 represents a perspective view of a third element of the shatterproof gate of figure 1 ;
[0024] - figure 7 represents a side view of figure 6.
[0025] With reference to the above-mentioned figures, a shatterproof gate according to the invention is shown as a whole with the number 10 and is clearly visible in figures 1 and 2.
[0026] Although the present embodiment of the invention is designed to pass an impact test according to IWA 14-1 :2013, it is not excluded that different embodiments of the invention may ignore the aforesaid impact test while still falling within the scope of protection of the invention.
[0027] Such a shatterproof gate 10 comprises:
[0028] - a substantially rectangular movable wall 20, clearly visible in figures 1 , 2, 3 and 4, comprising five reinforcing cables 22, clearly visible in figure 4 arranged along the longitudinal extension of such a movable wall 20 and each of which is fixed at its ends 22a and 22b at the side perimeter edges 20c and 20d of the movable wall 20;
[0029] - sliding means 21 and 32, clearly visible in figures 1 , 3, 4 and 5, configured to allow the translation of such a movable wall 20 along its longitudinal extension axis and orthogonally to the ground plane;
[0030] - a support structure 30, clearly visible in figures 1 , 2 and 5, provided with a base configured to be fixed to the ground and with at least a first gap 31 for the passage of the aforesaid movable wall 20 through such a support structure 30;
[0031] - a reinforcing structure 40, clearly visible in figures 1 , 2, 6 and 7, provided with a base configured to be fixed to the ground and with at least a second gap 41 adapted to accommodate one end of the aforesaid movable wall 20 when the shatterproof gate 10 is in the closed position.
[0032] The presence of the aforesaid reinforcing cables 22 allows to limit the flexural deformation of the movable wall 20 of the shatterproof gate 10 following a frontal impact with a vehicle.
[0033] Therefore, such a shatterproof gate 10 according to the invention is lighter with respect to a similar shatterproof gate of known type with the same resistance to a frontal impact with a vehicle.
[0034] Furthermore, the resistance to flexural deformation of the movable wall 20 associated with a frontal impact with a vehicle is greater with respect to a similar, known type of shatterproof gate.
[0035] It is further noted that the present invention provides for the presence of at least one of such reinforcing cables 22 which may therefore differ in number with respect to what is described in the present embodiment of the invention.
[0036] The movable wall 20 comprises five reinforcing tubes 23, clearly visible in figures 1 , 3 and 4, arranged along the longitudinal extension of the movable wall 20 and each of which is fixed at its ends 23a and 23b at the side perimeter edges 20c and 20d of the movable wall 20.
[0037] More precisely, each of the aforesaid reinforcing cables 22 is arranged passing through the inside of one of such reinforcing tubes 23.
[0038] The presence of such reinforcing tubes 23 allows to obtain a resistance to the flexural deformation of the movable wall 20 associated with an even greater frontal impact with a vehicle.
[0039] However, it is not excluded that the number of such reinforcing tubes 23 may be different from what is described in the present embodiment of the invention, and that each of such reinforcing tubes 23 has, passing through therein, a plurality of the aforesaid reinforcing cables 22.
[0040] The movable wall 20 comprises a limit switch profile 24, clearly visible in figures 1 , 2 and 3, fixed along a first side perimeter edge 20d of said side perimeter edges 20c and 20d, wherein said limit switch profile 24 is configured to block the translation of the movable wall 20 in the closing direction by mechanical interference with the support structure 30 around the first gap 31 when the shatterproof gate 10 is in the closed position.
[0041] Such a limit switch profile 24, in addition to acting as a limit switch for the movable wall 20 when the shatterproof gate 10 is in the closed position, also allows to hinder the extraction of the aforesaid movable wall 20 subject to a flexural deformation caused by a frontal impact with a vehicle.
[0042] The movable wall 20 further comprises a blocking profile 25, clearly visible in figures 1 , 2 and 3, fixed along a second side perimeter edge 20c of the aforesaid side perimeter edges 20c and 20d, wherein said blocking profile 25 is configured to block the translation of the movable wall 20 in the opening direction by mechanical interference with the reinforcing structure 40 around the second gap 41 when the shatterproof gate 10 is in the closed position and following a flexural deformation of the movable wall 20 with respect to its longitudinal extension axis.
[0043] This is understood to mean that, like the aforesaid limit switch profile 24, such a blocking profile 25 allows to hinder the extraction of the aforesaid movable wall 20 subject to a flexural deformation caused by a frontal impact with a vehicle.
[0044] However, it is important to emphasise that, unlike the limit switch profile 24, there is no mechanical interference between the movable wall 20 and the reinforcing structure 40 in the absence of flexural deformation of the movable wall 20 itself.
[0045] In the present embodiment of the invention, the sliding means 21 and 32 comprise a sliding guide 21 fixed along the lower perimeter edge 20a of the movable wall 20.
[0046] Furthermore, the aforesaid sliding means 21 and 32 comprise at least one carriage 32 fixed to the base of the support structure 30 at the first gap 31 and slidingly coupled to the sliding guide 21 so as to allow the aforesaid translation of the movable wall 20.
[0047] This allows to obtain a self-supporting configuration of the shatterproof gate 10, but it is not excluded that different embodiments of the invention provide different sliding means for the translation of the movable wall 20.
[0048] The reinforcing structure 40 comprises a reinforcing beam 42, clearly visible in figures 6 and 7, fixed to the base of the reinforcing structure 40 at the second gap 41 and arranged, as well as shaped, so as to allow its insertion inside the sliding guide 21 when the shatterproof gate 10 is in the closed position.
[0049] In particular, such a reinforcing beam 42 is configured to contact the inner surface of the sliding guide 21 following a flexural deformation of the movable wall 20 with respect to its longitudinal extension axis.
[0050] The presence of such a reinforcing beam 42 therefore allows to hinder the sliding of the aforesaid movable wall 20 subject to a flexural deformation caused by a frontal impact with a vehicle.
[0051] Furthermore, the reinforcing beam 42 has a substantially H-shaped transverse extension.
[0052] The movable wall 20 comprises a reinforcing plate 26, clearly visible in figures 1 , 2 and 3, fixed to a surface of the movable wall 20.
[0053] This advantageously allows to further limit the flexural deformation of the movable wall 20 following a frontal impact with a vehicle by increasing the flexural rigidity of the aforesaid movable wall 20 at the area of application of said reinforcing plate 26.
[0054] In the present embodiment of the invention, the first gap 31 is parallel and aligned with the second gap 41, as can be easily seen from figures 1 and 2.
[0055] It is not excluded, however, that such a first gap 31 and such a second gap 41 are not aligned, as long as they both allow crossing the movable wall 20 according to what has been previously described in the present embodiment of the invention.
[0056] Practically, it has been established that the invention achieves the intended task and objects.
[0057] In particular, with the invention, a shatterproof gate has been developed which is lighter and more transportable with respect to a similar shatterproof gate of known type, with the same resistance to a frontal impact with a vehicle.
[0058] Furthermore, a shatterproof gate has been developed whose resistance to flexural deformation of the movable wall associated with a frontal impact with a vehicle is greater with respect to a similar shatterproof gate of known type.
[0059] The invention thus conceived is susceptible to numerous modifications and variations, all of which are within the scope of the inventive concept; moreover, all the details may be replaced by other technically equivalent elements.
[0060] In practice, the components and materials used, as long as they are compatible with the specific use, as well as the dimensions and the contingent shapes, may be anyone according to requirements and the prior art.
[0061] If the characteristics and techniques mentioned in any claim are followed by reference signs, these reference signs are to be intended for the sole purpose of increasing the intelligibility of the claims and, consequently, such reference signs have no limiting effect on the interpretation of each element identified by way of example by these reference signs.
