Abstract
The present utility model relates to a retaining device for door/window shutters, comprising a shaped plate, which slidingly accommodates a spring-loaded slider inside it, suitable for blocking a catch that is provided with a step and is suitable to engage under a protruding chute made inside the slider.
Description
- The present utility model relates to the field of accessories for doors and windows, and in particular, it relates to a device suitable for retaining window shutters when they are fully opened.
- Various systems are known to keep a shutter in a fully open condition and for the most part, they are very simple mechanical systems, which differ according to whether they are equipped with elastic elements or are manually operated.
- Among the elastic-type retaining systems, the most common is certainly the one consisting of a small snapping clamp, fixed to an end of the shutter and a pin fixed to the wall, which engages inside said snapping clamp, when the shutter of the frame is in the maximum opening condition.
- Another known and extremely simple system consists of a T-bracket fixed to the wall, which has the characteristic of rotating on itself so that a 90° rotation suitable for positioning the T-bracket vertically, can retain a lower end of the shutter.
- A further known system to retain the shutter in maximum opening consists of a simple catch, which ends with a hook suitable to engage inside an eyelet constrained to the shutter.
- The known systems have some drawbacks, and, in particular, in case of devices using elastic elements, that of not being suitable to retain the shutter in case of strains due to particularly intense wind.
- On the other hand, mechanical retaining devices, such as T-brackets, have the drawback of losing their ability to block the shutter over time, due to play in the mechanism caused by its wear, forcing the user to make periodic adjustments to the distance of the bracket from the wall.
- The device of the present utility model solves the described problems, because the constraint made by means of a strong catch, which engages in a shaped plate with a spring-loaded slider, resists high strains; moreover, the release of the shutter by the user is quick and easy.
- A further object of the invention is to provide a retaining device, adaptable to any kind of surface by virtue of the use of appropriate spacers, which allow the height and position to be adjusted.
- A further object of the invention is to provide a compact and effective retaining device to be able to retain heavy door/window shutters that are different from those of common windows, such as door and gate shutters.
- These and other objects are achieved by the coupling device for door/window shutters of the present utility model described below in a preferred, non-limiting embodiment of further developments in the scope of the patent, with the aid of the accompanying drawings, which illustrate the following figures:
-
Fig. 1 , an isometric view of the shutter-retaining device; -
Fig. 2 , an exploded isometric view of the constituent components of the shutter-retaining device; -
Fig. 3 , an isometric, semi-sectional view of the retaining device with the catch in a blocking condition; -
Fig. 4 , an isometric, semi-sectional view of the retaining device with the slider translated to release the catch; -
Fig. 5 , an isometric view of the retaining device in the coupled shutter condition; -
Fig. 6 , an isometric view of a type of spacer to be applied to the shaped plate; -
Fig. 7 , an isometric view of the retaining device applied to a jamb and in the condition of partial opening of the shutter. - As illustrated in the accompanying figures, the coupling device for door/window shutters, hereinafter referred to as
retaining device 1, consists of ashaped plate 2, which slidingly accommodates aslider 3 inside it, suitable for blocking acatch 4. Thecatch 4 is constrained to the outer surface of the shutter by means of a pair of pins 51; conversely, theshaped plate 2 is equipped at its ends with a pair ofslots 22 suitable for accommodating a corresponding pair offixing pins 5 for fixing it to the jamb of the frame in the direction of theaforementioned catch 4. - As shown in
figure 2 , acavity 21 is made inside theshaped plate 2 in the shape of an inverted T for the entire length thereof, suitable for sliding the shape of theslider 3, whose geometry is the same T-shaped section as thecavity 21. - Both the
shaped plate 2 and theslider 3 are equipped, in a front position, with prismatic throughcavities catch 4 when the latter is contextually engaged to theslider 3 and housed inside theshaped plate 2. - The
cavity 21 of theshaped plate 2 is centrally crossed by a dowel 24, configured in twoportions prismatic cavity 23 made on theshaped plate 2. - To allow the
slider 3 to slide along theshaped plate 2 provided with the dowel 24, the geometry of the T-section of theslider 3 is provided with a longitudinalblind seat 32 suitable to accommodate said dowel 24 of theshaped plate 2. Said blindlongitudinal seat 32 of theslider 3 is further suitable to accommodate anelastic element 6 therein, which is accommodated between theend portion 24b of the dowel 24 and the end portion of the blindlongitudinal seat 32. - As can be seen in
figure 3 , in the blocking condition, theelastic element 6 has the function of retaining theslider 3 in an offset position relative to theshaped plate 2 so that thethrough cavity 31 of theslider 3 partially covers the throughcavity 23 of theshaped plate 2. The blocking condition illustrated inFigure 3 occurs when thecatch 4 advances perpendicularly towards theshaped plate 2 and, subsequently insisting on aprotruding chute 311 made on a side of the throughcavity 31, forces theslider 3 to move from its resting condition, translating to allow thecatch 4 to pass completely, until the condition of engaging itsstep 41 below saidprotruding chute 311, thereby finally achieving the blocking of thecatch 4. - As shown in
figure 4 , to allow thecatch 4 to be released from the previously described constraining condition, it will be necessary to push theslider 3 manually to overcome the reaction of theelastic element 6 and align the throughcavity 31 of theslider 3 with thethrough cavity 23 of theshaped plate 2 allowing the release of thecatch 4. - As illustrated in
Figure 5 , for the correct functioning of theretaining device 1, in the condition in which the shutter A is completely open, thecatch 4 engages inside the throughcavity 31 of theslider 3 exclusively by virtue of the geometric condition dictated by a fixed distance H, between the shutter A and the application surface S to which theshaped plate 2 is constrained. To reach said distance H, corresponding to the correct closure, theshaped plate 2, can be fixed onto the surface S parallel to the fully opened shutter A, usingsuitable spacers 7 to be interposed between theshaped plate 2 and the application surface S. As illustrated inFigure 6 , according to a preferred embodiment and in the case of application surfaces S which are not flat, the geometric section of thespacer 8 may assume any suitable shape to achieve the purpose of parallel alignment of theshaped plate 2 and the shutter A on which thecatch 4 is constrained. - As illustrated in
Figure 7 , in which a shutter A is shown partially rotated towards theretaining device 1, the heads of thefixing pins 5 of theshaped plate 2 and the heads of the fixing pins 51 of thecatch 4 are concealed by respectiveshaped plugs 9, 10, a first type 9 is constrained in theslots 22 of theshaped plate 2 and asecond type 10 adapted to be constrained in theslot 42 of thecatch 4.
