Description
INSECT SCREEN WITH BOX EQUIPPED WITH PROFILES FOR GUIDING
AND FACILITATING THE SLIDING OF THE PROTECTION NET
[0001] The present invention relates to an insect screen with box equipped with profiles for guiding and facilitating the sliding of the protection net.
[0002] The invention is applicable particularly, but not exclusively, to the sector of the industry for the production and marketing of screening devices and systems for building openings such as, in particular, insect screens, for example insect screens for doors and windows with vertical sliding, being applicable in particular to the industry for the production and preeminent marketing of insect screens and net-barrier elements for equipping building openings and widely in the industry for the production and marketing of components and accessories for frames.
[0003] In order to supply a screen which prevents the access of insects to inhabited spaces, all those long- and well-known barriers solutions, commonly indicated with the term insect screen, are usually supplied as equipment for doors, windows and skylights and are traditionally made of nets with dense mesh, each one having such dimensions as to prevent insects from crossing them, even if insects have limited dimensions, in any case said barriers being structured to prevent at least the most commonly annoying insects from entering. In an insect screen solution of the traditional type, it is provided a rigid frame bearing a dense mesh net having a suitable area according to the intended purpose, said frame being perimetrically compatible with the measures of the door or window opening which is intended to be equipped with the insect screen itself. According to the current, most common solutions, insect screens can be divided into two categories. A first category, the so-called "measure", is a type of insect screen made at the origin according to measures received by the customer and for its installation qualified personnel is required and a second category, indicated as insect screen in assembly kit, which usually can be installed by non-qualified personnel. With reference to both of the above-mentioned categories of insect screens, even though with prevailing reference to the category of insect screens in assembly kit, it is possible to find common construction elements, concretizing in the box of the type generally consisting of an aluminum extruded profile, in which the winding roller of the protection net of the insect screen is coaxially inserted and it retains a first end of said protection net. By means of said box, the protection net comes out from a suitable longitudinal opening, and it has the second end joined to a handlebar which is movable back and forth with respect to the box. In some solutions, the winding roller can also comprise a corresponding pre-loaded return spring to facilitate the rewinding of the protection net. Furthermore, as for the box ends, they are usually closed by suitable plates, which are supplied together with counter-plates of the adjustable type. In this solution, the box is provided with one or more guides or sliding elements, within which the end of the handlebar and the corresponding side edge of the protection net slide back and forth. Among various solutions of insect screens, other variants are also known, such as for example horizontally sliding insect screens, instead of vertically sliding insect screens, which cause the handlebar to make a translation movement which is directed to pull the net along a horizontal axis.
[0004] Also in the present patent literature, some solutions are found of insect screen structures, among which the following are mentioned, as mere examples:
D1 N. IT1304286 (Bonini)
D2 N. ITTV930004 (Bettio)
D3 N. ITTV20020031 (Bettio)
[0005] D1 briefly describes an insect screen for fast installation, comprising two identical and parallel guides in contact with the jambs of the window, at the top of which a box is fixed, containing the winding roller of the net and means for the automatic re-winding of the same net, said box being suitable for being placed on the upper part, in contact with the lintel of the window; said box being equipped with a lower, full- length opening for the shielding net to pass through, together with first upper elastic means, by means of which the box is in contact with the lintel of the window space and with second side elastic means by means of which the box is in contact with the jambs of the window space. Said first elastic means consisting of two leaf springs anchored along the upper side of the box, the function of which is to keep the insect screen elastically blocked in the window space in vertical direction. With reference to the second elastic means, they consist of a compression spring, acting in a horizontal direction between at least one of the plugs engaging the corresponding end of the torsion-spring and the respective external flange.
[0006] D2 briefly describes an insect screen and a device for blocking the relative components particularly in the packaging of a do-it-yourself kit, of the type consisting of a box inside of which a winding roller of the protection net and the corresponding pre-loaded return spring are previously inserted; said box providing on one side a kind of plate, associated to the profile, suitable for the engagement of the key of the loading pin of the spring, on the other side a disposable accessory made up of a cross element provided with means for supporting the other end of the winding roller and of the handlebar, being externally adjacent to one side of said box to be cut, for finally being replaced by a separated plate for supporting the winding roller only, which can be definitively engaged to the new end of a box to size so obtainable.
[0007] D3 briefly describes a solution of insect screen structure for doors or windows of the fast assembly type comprising a box inside of which a winding roller for winding and vice-versa a protection net possibly cooperating with the corresponding return spring, closed at its ends by plates in the form of caps of which at least one end is provided with supporting means of the corresponding end of the winding roller and two sliding elements placed in correspondence with and coupled to the ends of the box provided with longitudinal opening, defining rectilinear guides for the controlled sliding of the side ends of the protection net; in which at least one of the plates cooperates for fixing the insect screen with a corresponding counter-plate, which can be leaned against the space of the opening where the insect screen structure is required, said counter-plate being stressed by elastic deflection means arranged in the plate, and further in which, the latter is provided with a screw device for elastically adjust the distance with respect to the counter plate, whereas the counter plate is provided with a screw device for the elastic adjustment of the distance with respect to the box side from where the protection net comes out, at the end of which sliding elements are placed.
