Definitions
- the present invention relates to a frame for mosquito nets, sun shades or the like for veranda windows, balconies or similar locations, of the kind wherein a related stretch of material is mounted to slide on two frame posts.
- frames for mosquito nets, sun shades or the like constructed with opposed U-shaped section bars, wherein the edges of the mosquito net or curtain slide in loose coupling, and on said edges, depending on the type, a strip of PVC or similar material may be secured, whereon retaining buttons are applied at intervals.
- Such mosquito nets or curtains are united at the bottom to a horizontal bar for fastening to the frame.
- the side adherence of the mosquito net to the frame is not precise and it forms open spaces not covered by the net.
- the stretch of material is particularly voluminous when it is completely rolled up, i.e. raised; this entails the provision for cases of suitable capacity.
- the Italian patent for utility model No. 212.157 is aimed at solving this problem with a device able to keep the edges of the mosquito net or curtain material adhering to the related frames. It entails an arresting organ that creates an essentially punctiform pressure between the net and the related frame. Such an organ, preferably mounted on both posts, is able to hold fast and retain the stretch of material against the frame, but only limited to the pressure point, thus not being able to prevent, for the aforementioned reasons, the detachment of the stretch of material upstream and/or downstream of the point whereon the device acts.
- the essentially punctiform, or anyway localised, pressure exerted by the device on the stretch of material in practice always in the same place, over time creates a weakening in the pattern of the stretch of material, apt to lead to its progressive rupture.
- the object of the present invention therefore is to eliminate the drawbacks mentioned above, allowing in particular a stretch of material for mosquito nets, sun shades or the like to be unrolled and lowered and to be held fast in this position with a simple and rapid manoeuvre.
- Another object of the present invention is to allow the use of the mosquito net or the like without causing with its use any damages apt to reduce its working life.
- the invention solves the problem of providing a frame for mosquito nets, sun shades and the like, of the kind wherein a stretch of material for mosquito nets or the like is mounted to slide on two frame posts, which, from a general point of view, is characterised in that both posts of the frame comprise, each:
- the number 1 indicates a frame comprising a pair of equal opposed U-shaped posts, with parallel wings
- the number 2 indicates a stretch of material for mosquito nets to be fit in a window or other opening, for sun shades or the like
- the number 3 indicates a manoeuvring organ.
- each post is constructed with a semi-hollow section bar 10 comprising a shorter wing 11, whilst the other longer wing 12 presents a C-shaped end portion 13.
- the C-shaped portion 13 constitutes a seat for the holding means 4 ( Figures 2 and 3), such as a brush, a felt, a rubber gasket or the like.
- the holding means 4 has a support base corresponding to that of the C-shaped portion 13.
- the base side 14 of the U-shaped section bar. opposite to the opening of the section bar, is destined to be connected to the perimeter of the opening whereon the curtain is applied.
- the mosquito net material or the like 2 is mounted to slide on the posts of the frame 1, where the edges of the curtain are in loose coupling.
- a hinge pintle is obtained by means of a cylindrical groove 15.
- the groove 15 is preferably positioned on the base side 14, in particular on the side opposite to the wing 12 of the section bar 10.
- a plane section bar 5 (see also Figure 4), for instance in the shape of a bar, but possibly also curved.
- the section bar 5 presents, in cross section , at one end a circular pad 50 whose shape and size correspond to the groove 15 wherein it is engaged revolving coaxially.
- the opposite end of the section bar 5 presents a C-shaped portion 51, angled with respect to the plane of the section bar 5 so that, when the circular pad 50 of the section bar 5 is inserted in the groove 15, the C-shaped portion 51 is facing opposite to the C-shaped end portion 13 of the section bar 10, subsequent to the rotation of the section bar 5 from a position parallel to the wing 11 of the section bar 10 ( Figure 2) to a position in pressure contact with the stretch of material 2, shown in Figure 3.
- a manoeuvring organ 6 For the rotation of the section bar 5, on each post a manoeuvring organ 6 is provided.
- the manoeuvring organ 6 is mounted on a support element 60 joined with grooved couplings to the U-shaped profile 10 adjacently to the exterior of the wing 11.
- the manoeuvring organ 6 comprises a handle 61 for a lever 62 in a single piece therewith.
- the lever 62 is articulated at one end of a lever 63 by means of a cylindrical joint 64.
- the other end of the lever 63 is engaged with its own recess in an extension 65 projecting orthogonally from the end of the section bar 5.
- each post is constructed with a semi-hollow section bar 100 comprising two parallel wings 110, 110.
- Each groove 150 is preferably positioned at the ends ofthe base side 140, in particular in the inner end part of each wing 110 of the section bar 100.
- a pair of plane section bars 500 (see Figure 5), for instance in the form of bars, but possibly also curved.
- the section bars 500 like the section bar 5 of the first embodiment, engage in the grooves 150, whilst the opposite ends of the section bars 500 present a C-shaped portion 510, angled with respect to the plane of the section bar 500 in such a way that, when the section bars 500 are inserted into the grooves 150, the C-shaped portions 510 are apt to be tangential and symmetncally opposite one to the other. And this, following the rotations of both section bars 500 by means of a manoeuvring organ (not shown) for locking and holding fast the interposed stretch of material.

Abstract
Description
- a first U-shaped semi-hollow section bar with parallel wings, internally presenting at least one cylindrical groove developing over the entire length of the first section bar;
- at least a second section bar, rotationally hinged inside the related first section bar in said at least one cylindrical groove, having in the free end a seat for a means of retention;
- a manoeuvring organ for the rotation of said at least one second section bar from a position parallel to a wing of said first section bar to a position wherein said means of retention presses against said stretch of material.
- Figure 1 shows a schematic front view of a frame for mosquito net and the like according to the present invention.
- Figures 2 and 3 show a cross section according to line A-A of the frame in Figure 1 with the related manoeuvring organ in open and, respectively, locked position.
- Figure 4 shows a cross section of a first embodiment of a frame according to the present invention.
- Figure 5 shows a cross section of a second embodiment of a frame according to the present invention.
