Description

The present invention relates to a shielding for doors or windows frame equipped with side-scrolling lateral box, in particular of the type free of lower guide and used for the application of a self-enveloping shielding to doors or windows frame.
As is known, frames for the application of a self-enveloping side scrolling shielding, for example mosquito nets or curtains, having a lateral box and free of a floor guide, to a door or window opening comprise: - a box which is fixed, in vertical position, to the upper part of the compartment to be shielded and in which is wrapped a sheet of shielding material; - a horizontal top guide, in which the edges of the shielding are housed so as to prevent transverse movements of the shielding itself; - a pair of supports of the box adapted to secure the box to the sides of the compartment and to allow a certain tolerance in the cut of the box itself.
Furthermore, the supports of the box are equipped with a vertical edge which acts as a bearing surface of the box and allows, also, to determine a portion of space for containing an extreme portion of the box having variable length so as to adapt the box to compartments having different measures. In particular, the known systems having no lower floor guide require the presence of a vertically disposed box in which is wound the net and a of a carriage having modules for gripping the lower part of the net and which forms a sliding guide. In the extraction phase, the net can be pulled laterally by the user, by means of a handle bar, and, during rewind, the net is rewound quickly pulled by a spring included within the box.
Although functional in several respects, the solutions of the above type require special bulky profiles in which the modules of the carriage can scroll. Therefore, these types of shielding are not suitable for all existing profiles in doors or windows. Furthermore, during the opening and closure of the shielding, the handle bar of the shielding doesn't slide perfectly perpendicular to the axis of the lateral box. Consequently, particularly for bulky shieldings, the modules of the carriage have difficulty to go up along the handle bar, thus easily exiting from their seats.
Purpose of the present invention is to provide a shielding for doors or windows frame equipped with side-scrolling lateral box suitable to be free of lower guide which is not bulky and which allows the handle bar scrolling along an axis perfectly perpendicular to the axis of the lateral box and a controlled movement of the modules during the opening and the closure of the shielding, such as to overcome the limits of the known shielding.
According to the present invention, a shielding for doors or windows frame equipped with side-scrolling lateral box suitable to be free of lower guide is provided, as defined in claim 1.

With reference to these figures, a shielding for doors or windows frame equipped with side-scrolling lateral box free of lower guide is shown, according to the invention. In particular, figure 1 shows a shielding 200 for doors or windows frame equipped with side-scrolling lateral box free of lower guide, comprising: a net 201 self-enveloping inside a lateral box 202 vertically arranged and provided with an upper support 206 and a lower head 207 to be attached to the window frame; a fixed upper guide 203; a vertical closure profile 205 secured to the vertical wall of the frame or window frame, for example of a window, to which the shielding is applied, and which serves for locking the net 201 during its extraction from the box 202; a movable carriage 214 in which modules is hooked a portion of the net 201. The lateral box 202 comprises a roller tube, not shown in the figure, to which the net 201 is wound, and being engaged with the upper support 206 by means of an upper head and an upper bushing, not shown in the figure. A similar lower bushing 213 is configured to connect the roller tube with the lower head 207. The extremity of the net 101 able to be extracted from the box 102 is provided with a handle bar 208 that allows the user to laterally scroll the net 201, pulling it out easily when it is rolled up inside the box 202 and to stop it against the vertical profile 205. The handle bar 208 comprises, in fact, a central gripping element 209 to facilitate movement of the handle bar 208.
Advantageously according to the invention, the shielding 200 comprises a chute 215 with a housing for the modules of a carriage 214. As shown in Figure 2, the chute 215 is formed by a rectangular body 215a having both outer faces shaped in such a way to present a groove 215b extending, in a semicircular way, from the center of the top edge 215c to the lower corner of one of the side edges 215d of the body 215a. Moreover, the body 215a has, at the side edge 215e, a vertical groove 215f. On the top edge 215c of the body 215a, two pins 215h and 215i extend vertically. Moreover, the body 215a has a lower base 2151 having a thickness less than the thickness of the body 215a, therefore resulting recessed relative to the profile of the outer faces of the body 215a. Due to this configuration, the lower base 2151 can slide in the lower profile 225 acting as a guide for the modules 224, linked one by one, of the carriage 214, by means of two rails 225a and 225b extending along a lower profile 225, as shown in Figure 2C. Moreover, the body 215a of the chute 215 comprises, on each of the external faces, pins 215m e 215n configured for coupling the chute 215 to a first external lateral guide 216a and to a second external lateral guide 216b.
According to an aspect of the invention, the external guides 216a and 216b form a single body with the chute 215.
Advantageously according to the invention, the external guides 216a and 216b guarantee an optimal sliding of the modules 224 of the carriage 214 in the lower profile 225, particularly in the case that the profile 225 goes out of the binary of the floor in which it is installed.
Figures 2D-2F show images of the modules 224 forming the carriage 214. These separate modules 224 are able to be linked together on one side. More in details, each mesh 224 is formed by a circular body composed of two semi-circular portions 224a and 224b. The first portion 224a has, on both its faces, a cylindrical protuberance 224ab. The second portion 224b has, among its faces, a circular inner groove 224ba; holes 224bb in each face positioned so as to facing each other; on one face, a central protuberance formed by a cylindrical body 224bc terminating with a cylindrical head 224bd. Furthermore, the second portion 224b has a lower terminal appendix 224be extending toward the first portion 224. Figures 2D and 2E show, in particular, the coupling between two successive modules 224, realized in such a way that the cylindrical protuberance 224ab of a first mesh 224 goes to settle inside the holes 224bb of the second mesh 224.
The mobile carriage 214 is, therefore, formed by the set of modules 224 coupled as described. The so formed carriage 214 is inserted into the shielding 200, at the bottom between the box 202 and the handle bar 208 by means of the lower profile 225 which acts as a guide for the modules 224 of the carriage 214 since it is provided with the two rails 225a and 225b extending along the entire length of the lower profile 225.
Advantageously, according to the invention, the carriage 214 is inserted between the movable box 202 and the handle bar 208 by means of the lower head 207 appropriately designed to allow attachment of the modules 224 of the carriage 214. In particular, the head 207, shown in figure 2G, comprises a first region 207a that has a central cylindrical pin 207ab having on its upper part a parallelepiped pin 207ac which fits within the lower bushing 213 for engagement with the roller tube, not shown, a second region 207b with holes 207ba useful for the fixing of the head 207 to the window, and two fins 207c, 207d facing each other having the shape of a quarter of a round angle, positioned between the first region 207a and the second region 207b, and equipped, each on both faces, of a cylindrical protuberance 207ca and 207da. This configuration, as shown in figure 2H, allows to link the modules 224 of the carriage 214 in such a way that the holes 224bb of a first and of a second mesh 224 can accommodate the protuberances 207ca and 207da and allows to insert the lower profile 225 under the fins 207c and 207d, the modules 224 being able to slide on the rails 225a and 225b of the lower profile 225. In particular, the modules 224 slide, on the lower profile 225, outwardly to the rails 225a and 225b in such a way that the cylindrical body 224bc can slide under the rails 225a and 225b and the cylindrical head 224bd slide beyond the rails 225a and 225b, in the region comprised between these rails. Substantially a first row of modules 224 can slide on the lower profile 225 in such a way that the cylindrical body 224bc of the modules can slide under the rail 225a and the cylindrical head 224bd can slide beyond the rail 225a; and a second row of modules 224 can slide on the lower profile 225 in such a way that the cylindrical body 224bc of the modules can slide under the rail 225b and the cylindrical head 224bd can slide beyond the rail 225b.
According to an aspect of the invention, the lower profile 225 acts as a floor guide and has a thickness preferably equal to 4 mm.
Figures 3 and 4 show more in details the lower portion of the handle bar 208 engaged to the lower chute 215 by means of its upper pins 215i and 215h. Moreover, the shielding 200 comprises a magnetic linear profile 218 laterally hooked to the handle bar 208 and to the lateral edge 215e of the lower chute 215, by means of the groove 215f.
The movable carriage 214 is inserted in the lower portion of the shielding 200, between the box 202 and the handle bar 208, by means of the lower profile 225. The engagement of the carriage 214 with the box 202 is done by means of the lower head 207. So, the two rows of modules 224 of the carriage 214 sliding on the lower profile 225 insert in the groove 215b of the chute 215. When the chute 215 is interconnected with the handle bar 208 by means of the pins 215i e 215h, the two rows of modules 224 can climb a lower portion of the handle bar 208 respectively in an external groove 208a and in an internal groove 208b of the handle bar 208, as shown in figure 1B.
Advantageously according to the invention, the shielding 200 comprises a terminal element 234 hooked to the final mesh 224 of each row of modules. This terminal element 24 is provided with a hole 234a for the anchoring of a wire 235 vertically extending toward the superior guide 203, as shown in figure 5.
According to another embodiment of the invention, the handle bar 2008, shown in figures 6A, comprises a first protrusion 2008c facing the box 202 and a second protrusion 2008d opposed to the protrusion 2008c, a pair of lateral fins 2008e defining a first groove 2008a outside the shielding and a second groove 2008b inside the shielding.
Advantageously according to the invention, the lateral fins 2008e are configured to guide and contain the inside ascent of the carriage 214, as shown in figure 6B.
Advantageously according to the invention, this second embodiment of the handle bar is more robust and suitable to guide the meshes if the carriage along the handle bar and along the lower profile of the shielding.
Advantageously, as shown in figure 7 and in more details in figure 8, according to the invention, the shielding 200 comprises a system 226 for balancing the movement of the handle bar 108, having the function to push down the handle bar 208 on the lower chute 215. The system 226 comprises a first rectangular main body 226a provided, at its back, with a parallelepiped protrusion 226b through which the system 226 can engage and slide in the external groove 208a of the handle bar 208, and, on its front, with two snap pins 226c on which wheels 226d are hooked. Inferiorly, instead, the main body 226a has a cylindrical pin 226e around which is inserted the upper end of a spring 226f having the lower end inserted around a cylindrical pin 226g of a second body 226h comprising a locking hole 226i via an appropriate grain. Thanks to this mechanism, once that the spring 226f is pressurized, it is locked in position by compression of said grain. Advantageously according to the invention, the system 226 with wheels and springs, balancing the movement of the handle bar in the opening and closing of the shield and holding the handle bar down, when inserted in the upper portion of the external groove 208a, makes sure not to release the handle bar from the lower profile 225.
In addition, as shown in figure 7, the shielding 200 comprises a control system of the movement of the modules 224 of the carriage 214, comprising pulling wires 235, an upper chute 315, a guide stop 316, a guide stop block 317, a spring 318 and a wire rod 319.
In figure 9 the assembled parts of the control system of the movement of the modules 224 of the carriage 214 are shown. The wires 235, connected to the terminal elements 234 of the two rows of modules of the carriage 214, vertically extend, toward the upper fixed guide 203, along the external groove 208a of the handle bar 208 passing behind the balancing system 226, passing behind the chute 315 and continuing horizontally, below the upper fixed guide 203, in the direction of the guide stop 316 and crossing it, then going down towards the spring 318 to which are hooked, under the upper guide 203.
The chute 315, shown in details in figure 10, comprises a planar body 315a provided with a T shaped appendage 315b configured for engaging the handle bar 208, in closure configuration of the shielding 200, by means of lower pins 315c, 315d connectable internally to the handle bar 208, the planar body 315a having holes 315e for the passage of the pulling wires 235.
The guide stop 316, shown in figure 11, comprises comprises an adequately shaped body 316a provided with an appendage 316b provided with holes 316c for the passage of the pulling wires 235 and ending with a protrusion 316d configured for coupling the guide stop 316 with the guide stop block 317 and with the upper fixed guide 203. Once coupled each other, the guide stop 316 and the guide stop block 317 are coupled with the upper fixed guide 203 by meand of sliding and then they are fixed by means of a grain.
Figures 12 and 13 show the guide stop 316 coupled to the spring 318 and to the wires tie-beam 319. In particular, the wires 235, going out of the holes of the guide stop 315, end on the spring 318 to which they are connected. The spring 318 is coupled to the wires tie-beam 319.
During use, the wires 235 allow to drive and control the movement of the carriage 214, balancing the movement of the handle bar 208 by means of the balance system 226. In fact, driving the wires 235 by means of the wires tie-beam 319, during the opening or the closure of the shielding, the modules 224 of the carriage 214 can move in a balanced manner when the handle bar 208 is moved. In particular, when the shielding is closed and the handle bar is pulled toward the lower profile 205, the modules 224 of the carriage 214 pull the wires 235. Instead, when the shielding is opened and the handle bar is pulled toward the vertical box 202, the wires 235 pull the modules 224 of the carriage 214.
Advantageously according to the invention, the system for controlling the movement of the modules is more efficient depending on how much the sliding of the net hooked to the modules of the carriage is driven.
According to an aspect of the invention, as shown in figure 14, the modules 324 of the carriage present a planar upper protrusion 324a and are coupled, linked on two rows for forming the carriage, in such a way that the protrusion 324a of each module of the first row of modules is facing toward the inside of the shielding, thus being faced to the protrusion 324a of the module of the second row correspondingly coupled to it in the carriage. As shown in figure 15, since the net 201 is engaged, either stapled or buttoned up, between the modules of the carriage, the net is advantageoulsy comprised between the protrusions 324a facing each other of correspondent modules of the two rows of modules of the carriage 314, shown in figure 16. Hence, the protrusions 324a guiding the net 201 do not going out from the shielding, have an effect of containing the net which combines with the effect of controlling the movement of the modules, thanks to the control system described above.
Therefore, the shielding for doors or windows frame equipped with side-scrolling lateral box suitable to be free of lower guide according to the invention can be adapted to existing shielding systems due to the carriage scrolling in the external groove of the handle bar.
Another advantage of the shielding for doors or windows frame equipped with side-scrolling lateral box suitable to be free of lower guide according to the invention is that it's possible to use little bulky profiles for the assembly on the frame to be screened.
Another advantage of the shielding for doors or windows frame equipped with side-scrolling lateral box suitable to be free of lower guide according to the invention is that it allows that the handle bar slides along an axis perpendicular to the axis of the vertical box, controlling the escaping of the modules out of their seats in the lower profile.
Another advantage of the shielding for doors or windows frame equipped with side-scrolling lateral box suitable to be free of lower guide according to the invention is that it allows to control the movement of the carriage both during the opening and the closure of the shielding.
Another advantage of the shielding for doors or windows frame equipped with side-scrolling lateral box suitable to be free of lower guide according to the invention is that it's possible to better drive the net and avoid it escapes from the shielding.
A further advantage of the shielding for doors or windows frame equipped with side-scrolling lateral box suitable to be free of lower guide consists in the fact that it can be mounted, even by unskilled personnel, in a simple way and with no net blocks, constituting a real do-it-yourself kit.
Finally, the shielding for doors or windows frame equipped with side-scrolling lateral box suitable to be free of lower guide according to the invention is low cost.
Finally it is clear that the shielding for doors or windows frame equipped with side-scrolling lateral box suitable to be free of lower guide described and illustrated here can be modified and varied without departing from the protective scope of the present invention, as defined in the appended claims.
