Definitions

  • the present invention relates to a security device particularly for doors or window closure elements.
  • accessories which are activated automatically when the shutter (or blind) is lowered, preventing its lifting if it is not actuated by the motorized roll-up roller, which can be operated from the inside.
  • These accessories comprise blocks which are interposed between the roller and the top of the blind and substantially consist of a series of links, each of which is hinged to the next.
  • At least one link is arranged so as to apply a downward pressure and therefore a blocking action by interference, which prevents lifting.
  • the installation technician must choose the right accessory among a series of blocks of different length, with which he is provided, depending on the space available between the axis of the roller and the top of the blind.
  • this parameter is correlated to the roll-up diameter, to the distance of the roller of the guide and to the height of the slats of the blind.
  • the aim of the present invention is to solve the problems described above, by providing a security device, particularly for doors or window closure elements, for which installation is simple and fast, regardless of the dimensions of the elements involved.
  • an object of the invention is to provide a security device that ensures high reliability in operation.
  • Another object of the invention is to provide a security device that requires minimal maintenance interventions.
  • Another object of the invention is to provide a security device that can be obtained easily starting from commonly commercially available elements and materials.
  • Another object of the invention is to provide a security device that has low costs and is safe in application.
  • a security device particularly for doors or window closure elements, comprising a series of links arranged side by side and mutually articulated and adapted to wrap around a roller that can rotate and be blocked selectively, said roller being able to rotate about its own axis to move a door or window closure element that can be rigidly associated with an end link of said series of links, when the roller is blocked, the links interposed between said end link and an adjustment link connected to the roller are arranged, following an unwanted lifting of the door or window closure element, in a configuration for blocking by geometric interference and friction of the translational motion thereof, characterized in that it comprises means for selective coupling of the roller to one of a plurality of said links, the link chosen for coupling forming said adjustment link.
  • a security device generally designated by the reference numeral 1, comprises a series of links 2, 2a, 2b, 2c, which are arranged side by side and are mutually articulated and can be wrapped around a roller 3 which can rotate and can be blocked selectively.
  • the roller 3 which can have an octagonal cross-section according to various dimensions and can be for example of the motorized type, can rotate about its own axis in order to move a door or window closure element 4, which can be associated rigidly with an end link 2a of the series of links 2, 2a, 2b, 2c.
  • the rotation of the roller 3 thus causes the lowering of the door or window closure element 4, until access to a door or window is completely obstructed, or causes its lifting, until it is wrapped partially or totally, as shown in Figure 4 , around the roller 3, allowing access to the door or window.
  • the door or window closure element 4 can be for example a blind, a shutter, a vertically-hung shutter, or any other element for which the application of the security device 1 according to the invention is suitable.
  • the security device 1 can contrast the translational motion of the door or window closure element 4 in order to prevent the unwanted lifting thereof.
  • the security device 1 comprises means 5 for the selective coupling of the roller 3 with one of a plurality of links 2, 2a, 2b, 2c: the link 2, 2a, 2b, 2c chosen for coupling defines the adjustment link 2b.
  • each link 2, 2b, 2c, except for the end link 2a can be chosen as an adjustment link 2b according to specific requirements of application.
  • the means 5 comprise a pivot 6, which can be inserted selectively in any one of the respective recesses 7 formed in each link 2, 2b, 2c: it is therefore possible, during the installation of the security device 1 according to the invention, to identify in any link 2, 2b, 2c the one most suitable for constituting the adjustment link 2b.
  • the end portions 6a of the pivot 6 that protrude on opposite sides from the recesses 7 can be associated functionally with the roller 3 for its coupling to the chosen link 2, 2b, 2c.
  • the security device 1 comprises a pair of bushes 8, which can be fixed to the roller 3 (optionally by means of screws 9) on opposite sides with respect to the series of links 2, 2a, 2b, 2c.
  • a first link 2c which lies opposite the end link 2a, is pivoted to each bush 8 about an articulation axis which is parallel to the axis of the roller 3.
  • the means 5 comprise a plurality of receptacles 10, which are arranged peripherally along each bush 8.
  • Each receptacle 10 can thus receive and stably accommodate the end portions 6a of the pivot 6: thus, with the pivot 6 inserted in the recess 7 of the chosen link 2, 2b, 2c and the protruding end portions 6a inserted in the most suitable receptacle 10, the desired coupling of the roller 3 with the link chosen as the adjustment link 2b is provided.
  • the first link 2c, the adjustment link 2b and any links 2 interposed between them are wrapped around the roller 3, forming substantially a rigid coupling between the security device 1 and the roller 3.
  • the pivoting of the first link 2c to the bushes 8 around the above cited articulation axis is provided at a pin 11, which can be inserted in at least one eye 12 (two eyes in the embodiment shown in the accompanying figures) formed in the first link 2c.
  • Each bush 8 therefore comprises a respective seat 13, which in order to provide pivoting can receive and stably accommodate a respective end 11a of the pin 11, which protrudes outside the eyes 12 of the first link 2c.
  • the security device 1 comprises a plurality of springs 14: as is evident in particular from Figure 2 , each spring 14 is fixed to a respective link 2, 2a, 2b, 2c and abuts against the next link.
  • the elastic action of the springs 14 facilitates the extended arrangement of the links 2 interposed between the end link 2a and the adjustment link 2b and therefore the blocking of translational motion in case of an attempt to lift the door or window closure element 4.
  • the security device 1 comprises a covering ring 15 for each bush 8: for protecting the bushes 8 against scratches and/or dents, the material that constitutes the rings 15 has a high resistance to abrasion and is for example of the rubber type.
  • At least the end link 2a comprises a superficial coating layer 16, which is made of a material that also has a high resistance to abrasion and again can be of the rubber type.
  • the entire links 2, 2a, 2b, 2c of the security device 1 according to the invention might be made of such materials.
  • the end link 2a has a dovetail shape, as is evident for example from the accompanying Figures 1 and 4 .
  • This configuration makes it possible to contain the overall space occupation of the security device 1 according to the invention when the latter is completely wrapped around the roller 3, in the configuration shown in Figure 4 , which corresponds to complete lifting of the door or window closure element 4.
  • the operation of the security device according to the invention is as follows.
  • end link 2a is hinged to the top of the door or window closure element 4.
  • the remaining links 2, as well as the end link 2a are wrapped around the roller 3 only after a possible rotation of the roller 3 for lifting of the door or window closure element 4: the action of the roller 3 and the force applied on the links 2, 2a, 2b, 2c in this case is suitable for overcoming the elastic reaction of the springs 14.
  • the links 2 can, as mentioned, contrast the lifting of the door or window closure element 4.
  • the action of the springs 14 assists this extension and makes it possible to maintain this arrangement, facilitating the blocking of the sliding motion as a consequence of unwanted lifting processes of the door or window closure element 4.
  • FIGS 7 , 8 and 9 illustrate three different possible operating configurations, in which the choice of the adjustment link 2b is changed depending on the specific requirements of the application.
  • the protective scope claimed herein includes constructive and installation solutions that are different from the one described here in detail merely by way of illustration.
  • the security device 1 according to the invention can provide for fixing only the adjustment link 2b to the roller 3, even in case of a dimensional configuration such as the one of Figure 9 , choosing in any case to make the first link 2c coincide with the adjustment link 2b.
  • the versatility of the security device 1 according to the invention and the possibility of adapting it easily, as noted, to different contexts ensures a logistical benefit in terms of reduction of store reserves and/or the number of components to be transported to the installation site, as instead was necessary for known security devices.
  • the device 1 is substantially maintenance-free, while ensuring its effectiveness over time.
  • the security device according to the invention fully achieves the intended aim and object, since resorting to means for selective mating of the roller with one of a plurality of the links comprised within the security device, links which can arrange themselves in the configuration for blocking translational motion as a consequence of unwanted attempts to lift the door or window closure element, allows simple and quick installation, regardless of the dimensions of the elements involved.
  • the materials used, as well as the dimensions, may be any according to requirements and to the state of the art.
