LOCKING DEVICE FOR WINDOW LEAVES

Scope of the invention

The present invention relates to the technical sector relating to accessories for frames, doors and windows.

In particular, the invention refers to an innovative device able to tie together the sashes of a window or the sash to its frame, in such a way as to keep them in a partially open position with respect to each other in a stable.

Brief notes on the known art

As is known, a window is generally composed of two shutters hinged respectively to one side of the wall opening. The window can therefore be opened simply by rotating the two shutters in one direction around their hinges. In the same way, the window can be closed by rotating the two leaves in the opposite direction.

There are various forms of window sashes but all suffer from a common technical problem described below.

The two sashes of a window can be fixed to each other in the closed position by means of a common closing system well known in the state of the art. Generally a handle activates a pin coming out of a door and which is inserted in a seat of the adjacent door. In this way the two leaves remain coupled to each other in the closed position. In order to optimize closing, the rotation of the same handle generally also activates upper and / or lower pins which engage in fixed hooks or seats obtained in the wall. In this way, in the event of wind or voluntary forcing, the window remains tightly closed.

In the most common case, however, in which you want to keep the window open, there are currently no systems that prevent the two wings, or the single wing, from flapping freely, for example due to the action of the wind. Especially if you want to leave the doors half open between them, or if you want to leave a small light passing through, there are no systems able to constrain this position, thus avoiding that the doors (or the single door) are free to rotate. accidentally, for example due to the action of the wind.

Summary of the invention

It is therefore an object of the present invention to provide an innovative locking device for a wing window, or single wing and frame, which at least partially solves the aforementioned technical drawbacks.

In particular, it is an object of the present invention to provide an innovative locking device which allows the two leaves that are separated from each other to be stably maintained in reciprocal position (or the single door from the frame), thus maintaining a passage opening.

These and other purposes are therefore achieved with the present locking device for keeping a window, preferably a wing window, in a partially open position, according to claim 1.

According to the invention, the locking device comprises:

∠’A first and a second gripper element (10) for each one gripping of a window sash or a fixed part of the window and;

∠’A spacer element (1) to which the two clamp elements (10) spaced apart are connected.

With this simple system it is therefore possible to keep two sashes of a window in a relative semi-open position (or the single sash with respect to its frame). Once the pliers have in fact grasped a part of the door, the two doors are kept spaced apart from each other in a stable manner by means of the interposed spacer element, which creates a substantially rigid constraint (except for the flexibility and compliance of the element spacer itself) and preventing reciprocal opening and closing between the two doors.

Further advantages can also be deduced from the dependent claims.

Further characteristics and advantages of the present device, according to the invention, will become clearer with the following description of some embodiments, given by way of non-limiting example, with reference to the attached drawings, in which: ∠'Figure 1 shows a perspective view of the spacer element 1 while figure 2 and figure 3 show respectively a side view and a top view thereof;

∠’Figures 4 and 5 show in perspective view a symmetrical half of two possible forms of gripper according to the invention;

∠’Figure 8 shows the possible application of rubber pads 20 to the caliper;

∠’Figures 9 to 11 show the gripper assembly and spacer element coupled to keep the two doors spaced apart in use.

∠’Figure 12 and Figure 13 both show an application of this device in particular in the case of single-leaf windows.

Description of some preferred embodiments Figure 1 shows an axonometric view of a spacer element 1. This is in the form, for example, of a rod 1, or similar, and comprising a central portion 2 which joins two lateral parts (3, 4 ).

As better shown in the side view of figure 2, the central portion 2 is much thinner in thickness (s) than the height (h) of the side parts it joins. This gives considerable flexibility to the spacer element 1, thus resulting in much more efficient operation and easy assembly.

Going more into the descriptive detail of the spacer element 1, this can have a rectangular shape, that is, have a certain width (L) as shown in the top view of figure 3.

Of course, in a variant, the width (L) can refer only to the two lateral parts (3, 4) while the central part could have a different width, for example greater or less than (L).

In both solutions, in any case, this means that each side part (3, 4) can be provided with holes 6 passing through the entire thickness and within which, as explained below, they can be inserted by snap or by interference. (and therefore releasably) in each one a gripper element.

The spacer element is therefore delimited by a lateral perimeter 5 which configures it in a rectangular shape. The two lateral parts (3, 4) are therefore formed by this lateral perimeter 5 which configures them in such a way that they have a box-like shape. As can be clearly seen from Figure 2, the height h of both lateral parts (3, 4) is preferably much greater if compared with the height (therefore with the thickness s) of the central portion. In this way the entire spacer element 1 is very flexible around the central portion 2 while the lateral parts, used for the coupling and sealing action, are much more rigid and solid.

For example, it is possible to predict a height (h) of the order of one centimeter and a thickness (s) of the central part of the order of a few millimeters, for example about 3mm or 4mm.

Naturally these measurements are only indicative and not at all limiting, since the spacer element 1 can be made in different sizes and also with different materials (for example metals such as aluminum, plastic or wood).

The two lateral parts are therefore divided through transverse partitions 7 in such a way as to form said through openings 6.

In the case of figure 1, in a non-limiting manner, the side part 4 provides three openings 6 while the right side part 3 provides four.

Naturally the number of openings 6 obtained, both on the right and left side, can be any.

Continuing in the structural description of the invention, the openings serve to interlock (therefore with a certain degree of mechanical interference) the end 12 of a gripper 10 (see for example Figure 6).

For this purpose, precisely to facilitate their insertion in the holes 6, the ends 12 can for example be made with a tip, preferably rounded.

Going more into the descriptive detail of said gripper 10, this provides an upper part 11, used for gripping the leaf, and the stem 12.

The upper part 11 is therefore composed of two gripping surfaces (14, 15) forming a gripping vice 11.

The stem 12, as shown for example in figures 9, 10 and 11 of the present description, is configured in such a way as to fit into one of the holes 6 obtained on the spacer element with a predetermined degree of mechanical interference.

The skilled in the art can appreciate how infinite construction configurations are possible that allow this connection to be made with a selected degree of interference.

For example, you can simply select a shank diameter larger than hole 6 into which it is to be inserted.

The stem 12 can have any shape (for example circular or rectangular) and can be inserted into holes 6 also with any shape.

In the configuration described in the attached figures, the shank has a circular section and the holes 6 have a square section but, of course, different shapes could be selected.

The stem generally, regardless of its section, ends with a rounded shape. The rounded end is important to facilitate its entry into hole 6.

In a further variant, a shank 12 with a diameter smaller than or just equal to the opening 6 but ending with a rounded apex with a larger diameter than the hole 6 could be selected.

The mechanical interference can be selected in such a way that the gripper elements can be detached from the spacer element at the end of use or to change their positioning. However, the degree of mechanical interference must be such as not to make their detachment difficult by forcing a user but, at the same time, preventing accidental detachment during use, for example due to the wind.

The preferred configuration of the invention, described in figure 6 and in figure 7, provides a round shank 12 with a diameter such as to be inserted with interference in the hole 6. The shank then ends with a groove 13 which houses a circular ring with the function of spring.

The spring therefore serves to keep the two surfaces 14 and 15 forming the gripping vice 11 closed one against the other, exactly like a clothes peg.

The caliper can be made in one piece and with a return spring set up in a different way from that described.

Alternatively, as shown in figure 4 or 5, the pliers can be made in two halves that can be coupled together, as occurs for example in the common production of clothes pegs.

For example, figure 4 shows a half of a forceps equipped with a tooth 18 and a receiving seat 19. The other half is complementary and made in such a way that the tooth 18 of one half fits into the receiving seat 19 of the The other half . The ring spring holds the two parts together.

The technical advantage of a realization in two halves is certainly that of a simplification in the realization (for example in the mold) with freedom of choice of the type of elastic return element to be applied.

Advantageously, one or more rubber pads 20 are then provided which can be applied to the surfaces 14 and 15 used for gripping (or even to only one of them).

The use of rubber pads prevents damage (for example scratches) of the door when it is grasped and allows it to be adapted to different thicknesses of the doors.

The rubbers, as shown in figure 8, can be applied in a detachable manner by means of pins integral with them which are inserted in special holes made on parts 14 and 15 (see figure 8).

Alternatively, they can be glued directly on the faces of the vices, i.e. on the faces of surfaces 14 and 15.

It is evident that different conformations of the gripper portion that comes into contact with different leaf profiles can still be realized. For example, the clamp of figures 9, 10, 11 is well suited to windows with a standard aluminum profile. In another example, one of the two surfaces (14, 15) of the gripper may have a length (plane of contact with the sash) longer than the opposite one. In this way, the clamp is well suited to particular shapes of doors or frames to which it clings.

Figures 9, 10 and 11 show the device assembled as a whole, i.e. two gripper elements inserted each one respectively into a hole 6 of a respective side part (3, 4) and facing opposite directions.

The pliers can be freely rotated in the hole in order to select the preferred orientation.

The application, as shown in figure 9, is with the pliers inserted in an opposite way because in use this configuration allows you to easily grasp two leaves that are spaced apart.

However, this coupling configuration is not the only one possible.

In use, the user selects the distance between the pliers, based on the opening width he wishes, and proceeds to insert them in the 6 selected holes.

The presence of several holes 6 allows the clamps to be adjusted at different distances and therefore makes the device as a whole versatile. It is therefore possible to adjust openings between the different doors.

The flexibility of the spacer element dampens the relative forced movement between the leaves, for example due to the action of the wind and, moreover, facilitates its application.

In a further variant of the invention, a device such as that of figure 9 could be realized in which, however, there are no longer holes 6 placed at different distances but only one hole on each side (3, 4). The device would still work but would not allow you to adjust lights of different opening.

In a further variant the same inventive concept described here could be realized but by making the pliers integral with the part (3, 4) to which they are connected, that is without the possibility of being able to detach them from the spacer element and then reapply them if necessary.

Figure 12 therefore schematises a leaf 100 and a frame 101 to which the present device is applied in such a way as to keep them in a semi-open position.

Figure 12 highlights the flexibility of the central part 2 which facilitates assembly. For example, it is possible to fix a gripper element in the selected hole 6 and apply the gripper element to the fixture 101 and then insert the second gripper element into a selected hole on the opposite side, once the gripper has grabbed the door 100.

Figure 13 shows an application in which the sash of a single-sash window is always kept open. In this case, as explained, one pliers are designed to grasp the profile of the sash while the other grasps the profile of the frame. The spacer element maintains the semi-open position of the door, the opening of which can be adjusted in the case of a spacer element with several holes 6.

Although a use referred to the mutual fastening between frame and sash has been described, it is clear that the same device can be applied to any type of window, for example with two wings.
