This invention relates to a unit of tilting window on its lower edge, specifically a unit  tilting window on its lower edge whose frame is made of metal, PVC or similar materials, wood- PVC, etc.

Currently, the tilting windows on your bottom edge are widely used because they satisfy a wide range of requirements in buildings of all types (residential, schools, hospitals, factories, etc.).

Windows of this type are installed in parts of a building that are not easily accessible as is the case, for example, of lintel or skylight windows (normally over a door) or that are very high (such as example, in factory buildings) and that preferably open using a suitable actuator or other instrument with means of hitch on its upper end.

Typically, such a window has two engoznado points between the movable frame and the fixed margo on its horizontal bottom edge and a single point by which the movable frame over the upper horizontal edge.

The single closing point, which is located normally half the width of the window frame, It consists of a well-known device that, familiar with the profession, they call "latch".

The latch is basically an element of clamp consisting of a pin mounted on support means suitable (plates) attached to the mobile frame, and a pusher element attached to the fixed frame. The pusher element (usually a inclined surface) is normally coaxial with the pin of the latch that can slide axially (both ways, thanks to a spring) towards a hook groove located in the inner end of the pusher element. The outer end of the latch has a ring handle that can be operated by hand or hooked by a hook or actuator.

With this device, the user can free the latch pin of the hitch groove so that the gravity cause the movable frame to swing inwards room in which it is installed. To close the window, the user pushes the moving frame towards the fixed frame until the pin is secured with springs inside the groove.

Although this type of window is used widely, its structure presents several problems that have not yet been resolved

The main drawback of this type of window is of course the closing device in a single point.

The single closing point makes it difficult to close the window successfully because, among other things, the windows of this type normally have irregular proportions (very wide and low, very narrow and high, depending on the requirements) and therefore, the single closing point that is normally located, As mentioned earlier, it cannot present a tightness effective nor sufficient guarantee of security in all of the window.

Specifically, the single closing point offers poor resistance against potential floor assailants and apply insufficient pressure on the gaskets, especially in the corners furthest from the closure, presenting a tightness inefficient against rain and / or drafts (as well as little noise insulation). The objective of this invention is overcome the aforementioned inconveniences by providing a operating device to open and close tilting windows on so bottom edge that is very versatile and that can be mounted on tilting windows on its bottom edge of all types and sizes and that offer a high level of security, effective sealing outdoors and easy operation to open and close the window.

According to the invention, the objective before mentioned is achieved by a tilting window unit on its lower edge according to the characteristics of the attached claim 1.

The technical characteristics of the invention, with reference to the above objectives, they are described clearly in the attached claims and their advantages are evident in the detailed description that follows, with reference to the accompanying drawings illustrating a preferred embodiment of the invention presented merely by way of example without limiting the scope of the concept of the invention, and in which:

- Figure 7 is a plan view from above schematic, with some parts removed, of a detail of Figure 6 showing the action of the operating medium that moves the window from closed to open configuration.

With reference to the attached drawings, specifically figures 1 to 3, the window unit according to  The invention is of the tilting type on its lower edge.

This type of sales unit, which bears the numeral 1 in its entirety, basically comprises a mobile frame 2 and a fixed frame 3 hinged together, in 3i, by a pair of bodies of conventional hinge, along a respective crossbar 4 and a drive means 5 for opening and closing the unit 1 of window.

More specifically, mobile frame 2 and frame 3 fixed have each respective C2 and C3 longitudinal grooves in which may be installed operating accessories.

As shown in Figure 2, the means 5 of drive act between a second crossbar 6a and 6b, parallel and opposite the first crossbar 4 on which the movable frame 2 is attached to the fixed frame 3.

The drive means 5 allow the movement of the window between an open configuration, in which the second crossbar 6a of the movable frame 2 is remote from the respective second crossbar 6b of the fixed frame 3 (i.e., in which the movable frame is inclined towards the interior of the room with respect to the frame 3 fixed) and a closed configuration in which the transom 6a mobile is in contact with the crossbar 6b said (see arrow F2 of the figure 2). The open position with a predetermined angle is achieved by means of a rod brace, which bears the numeral 2t and that is not describe in detail because it is of a well known type.

The drive means 5 comprise the minus an operating means 7 located on the mobile cross member 6a and which has at least two elements 8 and 9 to close the mobile frame 2 against fixed frame 3.

The closing elements 8 and 9 are spaced each other and can be safely coupled to the respective pushers 10a and 10b located on crossbar 6b of frame 3 permanent.

In addition to the above, means 11 are provided to act on the operating means 7 and activate frame 2 mobile so that window 1 automatically moves from the configuration open to closed.

As shown in Figures 1 and 3, the closure elements 8 and 9 mentioned above preferably, but not necessarily, they are equally spaced from a central point located on the mobile cross member 6a.

Specifically, the two closing elements 8 and 9 they can be located next to the respective corner areas of the transom 6a mobile.

Two points are shown in the attached drawings of closure but it should be understood that there can be many more points closing, depending on the shape and size of the window.

Looking more closely at the technical details (see Figures 3 to 6) the drive means 5 comprise furthermore an activation element 12 located outside the transom 6a mobile and acting on the operating means 7 of such that it allows at least the operating means 7 to pass from the closed configuration to the open.

More specifically, the activation element consists of a lever or handle 12 that rotates around an axis perpendicular to the plane of the movable frame and is associated with a rod 15 housed in a respective protection element 16 associated with the exterior of the mobile cross member 6a.

The stem 15 has a pin 17 that protrudes radially and engages a recess 18 made in a first part Operational 19a of a slide 19 to move a rod 7a of drive located on the mobile cross member 6a.

A second operative part 19b of the slide 19 extends in the mobile cross member 6a through a slot 20 made in the mobile crossbar 6a itself; in use, part two 19b internal operation intervenes between two contact elements or projections 21 and 22 located on rod 7a (see figure 6) of such that it allows the same rod 7a to be operated in both directions, corresponding to the closed settings and open mobile frame 2 (see arrows F7a).

As already mentioned, the operating means 7 they comprise the aforementioned drive rod 7a, which It is slidably installed in groove C2 of crossbar 6a mobile.

As clearly shown in Figures 3 to 6, the drive rod 7a is associated with the projections 8 and 9 that stand out vertically and constitute the former mentioned closing elements.

Automatic exchange 11 before mentioned include return means 13 and cam means 14 located next to the two pushers 10a and 10b.

More specifically, the return means 13 they act on the lever or handle 12 in such a way that they return lever 12 to the closed window configuration without apply any force to said lever 12 (see arrows F12, Figure 5).

As clearly shown in Figures 3 to 6, the return means consist of a spring 13 interposed between the first operative part 19a of the slide 19 and an element 23 of contact protruding perpendicularly from the mobile cross member 6a on a mounting plate 24 attached to the crossbar 6a itself mobile.

The cam means 14 mentioned above are located, as stated, in the proximity of the two pushers 10a and 10b operate on the respective protrusions 8 and 9 in such a way that make:

-

that operating means 7 pass momentarily from the configuration closed to the open so that the mobile cross member 6a can move as close as possible to the fixed crossbar 6b (see arrow F70, Figure 7);

-

Y, then, that the two projections 8 and 9 engage the pushers 10a and 10b safely by the action of the recovery spring 13 which moves the rod 7a and the lever 12 to the closed position (see arrow F71, Figure 7).

The pushers may consist of at least two blocks 10a, 10b located on it and connected to the fixed crossbar 6b in the respective longitudinal C3 groove (through plywood 10c conventional that act between the groove C3 and the respective block 10a, 10b).

Each block 10a and 10b has a half slot 25, open inside the mobile crossbar 6b, to engage securely a respective protrusion 8 and 9 in such a way that defines the aforementioned closed configuration.

In addition to this, each block 10a and 10b has a first surface 14, in front of the mobile cross member 6a with a inclined profile to push the respective protrusion 8 and 9 and, in the practice, constitute the aforementioned cam means.

In this way, the contact between the projections 8, 9 and the first surface 14 when the crossbars 6a and 6b are approach each other, it results in:

-

the projections 8, 9 (and, therefore, the drive rod 7a) are move from the closed to the open position so that the two crossbars 6a and 6b can move as close as possible possible;

-

Y, next, projections 8 and 9 automatically return to the configuration closed by the action of the recovery spring 13, of such that it immobilizes the protrusions 8 and 9 in the recess 25 of blocks 10a and 10b (see again figure 7).

In addition to this, each incoming slot 25 means has a second profile 26 to get in touch with the respective protrusion 8, 9 and inclined in the opposite direction to that of the first surface 14, so that the crossbars 6a and 6b mobile and fixed can be pressed to bring them closer together yet more, thus compressing the weatherstrip (not illustrated) when the window closes.

Continuing with the reference to figures 3 to 6, the first operative part of the slide 19 consists of an element C-shaped 19a that has the function of shelf with a single incoming defined by the aforementioned incoming central 18 for hook a central area of pin 17, and two walls 19c and 19d ends that have respective cylindrical protrusions 28, 28 ' facing one of which at least is designed to hook (by insertion inside) the end of the spring 13 which constitutes the means of return.

The lever or handle 12 comprises another aspect that it is a ring 27 to be grasped by the user's hand or to engage by an actuator or other suitable T tool (shown in Figure 2 with dashed lines) which allows the return of the lever 12 to open window 1.

Finally, the protection element 16 mentioned above may be equipped with a bump 29 out to engage the lever or handle 12 and keep the lever 12 in the position corresponding to the configuration closed frame 2 mobile.

In use, the window 1 according to the invention It can be opened and closed as follows: the user can turn the lever 12 down by operating it directly or, if the Window is out of reach, using a T actuator, thereby compressing spring 13 (see arrow F13, Figure 5) and moving the slide 19 (in the direction of the arrow F19) so that it activates the rod 7a of drive

The slide of the rod 7a allows protrusions 8 and 9 move momentarily away from incoming 25 of blocks 10a and 10b, which allows mobile frame 2 swing into the room (see arrow F2, Figure 2).

The spring 13 displaces all means 7 operational and causes lever 12 to return to configuration closed as soon as the force applied to said lever ceases 12.

To close window 1, it is enough to push the movable frame 2 towards the fixed frame 3 until the protrusions 8 and 9 contact the first surface 14, by operating this way the rod 7a and displacing the operative means 7 (now in the closed position) to the open position. He momentary displacement is also transmitted to slide 19 and to lever 12, thereby compressing spring 13.

This momentary open configuration allows that protrusions 8 and 9 move beyond blocks 10a and 10b and that they are located near their recesses 25 (in figure 7, the displacement is indicated by arrows F70).

At this time, the recovery pier 13, compressed previously, allows protrusions 8 and 9 to be located in recesses 25 of blocks 10a and 10b, since it no longer exists any resistance of the respective contact surfaces 14, thus securing window 1 in its position fully closed (see again the arrows F71 of figure 7).

A window unit made as described previously achieved the aforementioned objectives thanks to a combination of components that form a closure system extremely practical and with multiple insurances that includes the automatic window closing.

The presence of the sliding rod with two or more outgoing determines a closure that is both safe, no weak points and balanced according to the shape and size of the window.

The use of a slide, operated towards the closed position by a spring, and cam-type pushers makes possible to close the window quickly, effortlessly and with certainty that the window is perfectly waterproofed against the wind and rain and safe against floor raiders.

It is desired to clarify that the described invention can be useful in many industrial applications and that can be modified and adapted in different ways without leaving the conceptual scope of the invention. In addition, all the details of the invention can be replaced by technical elements equivalent.
