Description

Door or window handle with opening swivel or with swivel and tilt opening.

The present invention relates to a handle both for revolving doors and windows and for revolving and tilting opening doors and windows, in particular to a failed type handle that may be provided with a device Safety lock against false maneuver.

The present invention relates in particular to fail type handles, applicable to door or window frames and which are made of metal, for example aluminum, but without this restricts the scope of the invention.

Type handles normally failed include:

- a handle body, usually in shape prismatic

- a maneuvering handle protruding from a side of the handle body;

- control elements protruding from the side opposite to the handle body and designed to operate the device to close the frame;

- means for fixing the handle to the frame, the latter having holes or slots for passing the control elements and for the same fixing means-
tion.

The doors and windows that are currently they have available on the market can basically be divided in two types: one where the frame can be opened only by rotation and another where the frame can be opened both by rotation and by tipping

In the case of doors and windows that open only by rotation (the most common, of the two this one could consider the traditional type), the command elements include two cursors that protrude from the handle body and that, when they are applied to the frame, they are coupled with the sliding rods of the opening and closing mechanism (for example, lower bolts and upper to enter in corresponding seats).

The two cursors (see also the patent for invention EP 446.566) are guided in their approach movements  and reciprocal withdrawal along the handle body by a pair of parallel zippers, whose teeth mesh with a pinion. The pinion rotates in solidarity with a tree attached to the handle of way to open and close the frame when the handle.

In addition, the handle body has a plate of coverage set to it and designed to keep together the zippers and part of the arrow keys. The cover plate has a group of holes at each end, through which they introduce fixing means, and at least one slot where move, guided, the arrow keys.

In the case of doors and windows that open by tilt or rotation, as also described in the patent of invention EP 1,036,899 A2, the handle differs from that described with prior to the fact that it has a single cursor that stands out of the handle body and that was devised to be coupled with a control element connected to suitable means to carry the opening and closing mechanisms of the frame to the configuration that want.

In this type of doors and windows, the handle can be taken to at least three configurations different.

It must, therefore, be provided with a device "safety lock against false maneuver" to lock the handle in the open configuration chosen by the user (inclined or rotated), thus preventing accidental maneuvers that could create problems not only for security but also for the subsequent closing of the door or window.

The device applied to the handle according to the The present invention is based on a known constructive solution, available on the market, where the device is installed directly on the maneuver cursor.

In practice, the cursor consists of a fork guide that slides a sliding plate provided of a spring inserted between the base of the same sliding plate and an internal part of the cursor.

The sliding plate can move between a retracted non-operative maneuver position (closed frame), where the same sliding plate is fully inserted inside the cursor thanks to the contact with the fixed frame of the door or window, and a advanced operating position of handle maneuver lock (open frame in one of its configurations), where the plate Sliding partially protrudes from the cursor, thanks to the push exerted by the spring; this movement (in one of the solutions known) causes one of its bumps to bond with one of the corresponding seats made in the aforementioned plate  coverage (preferably) and prevents the cursor from moving.

Handles of the type described above have proved to be extremely useful and practical, however with the Over time they present management problems and cost of storage for manufacturers of door accessories and windows

This is due to the fact that there are two different handle solutions, one for each type of door or windows (traditional and rotating / tilting) the need is generated to maintain separate stocks of handles already assembled from two types, which leads to higher management costs.

Given this problem, the applicant now proposes a handle that includes the same essential parts satisfying the requirements of both types of doors or windows currently requested but with features advanced accessories that give the same handle the possibility of being adapted both to a traditional door or window and to a tilt / swivel door or window.

The invention achieves this objective by means of a handle for both doors and windows opening by rotation and for doors and windows opening by tilting and rotation as expressed in claim 1.

The technical characteristics of this invention, with reference to the above objectives, are described very clearly in the claims that are most forward and its advantages will become apparent from the Detailed description that follows, with reference to the attached drawings which exhibit a preferred embodiment of the invention provided to purely exemplifying title without restricting the scope of the inventive concept, and in which:

- Figure 1 is a schematic side view, with some parts omitted to better illustrate others, of a handle according to the present invention, in a first application;

- Figure 2 is a schematic side view, with some parts omitted to better illustrate others, of a handle according to the present invention, in a second application;

- Figure 3 is an exploded perspective view of the handle shown in figures 1 and 2;

- Figures 4 and 5 illustrate a first detail of the handle of figure 3, in a plan view from above and in cross section through the V-V line, respectively;

- Figure 6 illustrates a second detail of the handle of figure 3 in a perspective view;

- Figure 7 illustrates a third detail of the handle of figure 3 in a perspective view;

- Figures 8 and 9 are plan views from above and a cross section through the line IX-IX of an alternative embodiment of the Handle control elements shown in the drawings listed above.

With reference to the attached drawings, in particular with respect to figure 2, the handle shown, denoted in its entirety by numeral 1, it is used to maneuver frames of doors or windows made of any one of a variety of different materials, for example made of metal.

In particular, the handle is suitable to be used with doors or windows of both the traditional type, which they open by turning, like the type that is opened by tilting or turning.

While the handle (1) to which it is made reference in this description is the type of fail, the structure according to the present invention could be applied to others Handle types without impairing its original character.

As shown in Figure 3, the handle (1) essentially it comprises a handle body (2) from which protrudes, from the side with a bushing (2a) made of a single piece with the handle body (2), a handle (4) used to move the means (8) of kinematic transmission, and elements of maneuver (5) on the other side of the handle body (2).

The kinematic means (8) comprise a tree (8a) housed inside the handle body (2) and a zipper (8b) whose teeth mesh with a pinion (8d) that rotates in solidarity with the tree (8a).

The free ends of the maneuvering elements (5) are linked to the frame closing devices (6 and 7) (not important for the purposes of the description of the invention and, for therefore, not illustrated in detail) represented in Figure 1 as a flat rod provided with contact elements (6a and 6b), and in Figure 2 as a contact element (7).

More in details, the rotation of the handle (4) causes the maneuvering elements (5), subjected to the action of kinematic media (8), move between different positions stable that correspond to the closed and open configurations of the frame (A) (see arrow F of figures 1 and 2).

The maneuvering elements (5) illustrated they comprise a cursor element (10), which constitutes the element that sends the opening and closing devices (6 and 7) of the frame, and means (11) for blocking the individual cursor element (10) in the different positions corresponding to the configurations of overturned and rotated opening of the frame.

The zipper (8b) comprises a part of maneuver (10t) presented by the cursor element (10) and that allows the latter to move between different stable positions corresponding to the open and closed settings of the framework.

The handle body (2) also has a plate of coverage fixed to it and designed to protect the whole kinematic (8) and the part of the cursor element (10) connected to the set.

The cover plate (9) has a group of first holes (9a) at each end, through which introduce fixing means (3) (for example, screws) to fix the handle body (2) to the frame.

Also, as clearly shown in the figure 7, the cover plate (9) also has at least one groove of guide (9b) through which the cursor element (10) protrudes.

As illustrated in Figure 3, those before mentioned blocking means (11) are placed on the element cursor (10) so decomposable, which is equivalent to saying, of so that they can be separated.

More exactly, the blocking means (11) is you can slide inside the individual cursor element (10) from the free outer end of the same cursor element (10) after the latter has been fixed to the handle body (2).

In practice, this possibility allows the handle (1) in its simple configuration, which is equivalent to saying, only with the cursor element (10), it can be fixed to frames that are open only by rotation while simply adding the locking means (11), the handle (1) can be applied to frames which open both by rotation and by tilting.

To quickly change from one type to another, the The present invention contemplates the provision of non-reversible means (12) to fix the locking means (11) on the handle (1) and act on the blocking means (11) when the same means of Lock (11) are inserted into the cursor element (10).

Looking more closely, the means of lock (11) (see also figures 4 and 5) comprise a plate sliding (16), slidably housed inside the element cursor (10), and spring means (17) located between the same plate sliding (16) and the cursor element (10) when the same sliding plate (16).

The spring means (17) allow the plate Sliding (16) moves between a non-operative retracted position of maneuver of the cursor element (10), where the same sliding plate (16) is fully inserted into the cursor element (10) thanks to contact with a fixed door or window frame (no illustrated), and an advanced operational position for locking the cursor element, where the sliding plate (16) protrudes partially of the cursor element (10) (see figure 2).

The fixing means (12) hold the plate sliding (16) securely in the cursor element (10) in the operating position locked, since the non-operating position has jumped into the inner part of the handle body (2).

On a constructive level (again with reference to Figures 4 and 5), the sliding plate (16) comprises a head operating end (20) and a projection (21), at the opposite end, which comes into contact with a fixed surface defined by the plate cover (9) of the handle body (2).

The sliding plate (16) also has a second central groove (22) containing a part of the spring means (17), which are located with one end in contact with a second contact bolt (23) also made on the plate sliding (16).

In practice, when the sliding plate (16) (which constitutes a device also known as "blocking of security against incorrect maneuvers ") is installed on the cursor element (10), its end head (20) tends to protrude and, with the projection (21), is linked in a corresponding opening (9c) made on the cover plate (9) stopping the element cursor (10): this happens, as you know, when the frame (A) is open.

As also shown in Figure 6, the cursor element (10) is shaped like a "C" to form a pair of guides (10a), on each side, to slidably contain the sliding plate (16), and a first central guide groove (18) for the spring means (17) located with one end touching a first contact bolt (19) made in correspondence of the end internal element cursor (10).

With the maneuvering elements (5) made of this way, in a first exemplifying embodiment and not restrictive, the aforementioned fixing means (12) are located on the sliding plate and operate between the same plate sliding (16) and cover plate (9).

More exactly (see figures 3 to 7), such fixing means (12) can comprise a tooth (13) made on the cover plate (9) (preferably in one of the before mentioned openings (9c)).

The tooth (13) can be linked with a end protuberance (11a) protruding from the projection (21) of the sliding plate (16) when the sliding plate (16) is housed in sliding way inside the cursor element (10).

The tooth (13) is elastically mobile (see the arrow F1 of figure 7) from a position where the bump (11a) passes beyond the cover plate (9) and the tooth (13) is inside the cover plate (8) through the linkage with the protuberance (11a), to a position where the bump (11a) is locked inside the cover plate (9), the tooth (13) being arranged in the same plane of the plate of coverage (9) and the protuberance (11a) being stopped against the same tooth (13).

This plate lock setting Sliding (16) is established during assembly with the tooth (13) leaning on the surface of the frame (A).

In a second exemplary embodiment (see Figures 8 and 9), the aforementioned fixing means (12) are located on the sliding plate (16) and operate between the same plate sliding (16) and the cursor element (10).

In this embodiment, the fixing means (12) comprise at least one elastically deformable appendix (14) made in the cursor element (10), the appendix (14) protruding from the plane in which the sliding plate (16) slides in the cursor element (10)

Apart from the above, there is a lobe (15) made at the lower end of the sliding plate (16) and that, once the cursor element (10) is entered (see arrow F2 of figure 9), comes into contact and moves beyond the appendix (14), thereby holding the sliding plate (16) inside of the cursor element (10) when the appendix (14) returns to its state outstanding so as to stop the lobe (15) (see arrows F3 of figure 9).

In the first embodiment described with previously, the sliding plate (16) can be introduced from sliding way inside the cursor element (10) after the latter has been stably fixed to the handle body (2) but before the handle (1) has been fixed to the frame (A).

In the second embodiment described with previously, the sliding plate (16) can be introduced from sliding way inside the cursor element (10) after the latter has been stably fixed to the handle body (2) and after the handle (1) has been fixed to the frame (A).

The handle made as described above achieves the aforementioned objectives thanks to a simple variation of the structure of the maneuver elements of the handle, which allows the sliding plate to be inserted into the cursor element by a simple manual operation only when necessary adjust the handle to doors or windows of the swivel and tilting type.

The invention has the following advantages:

- reduced stock of handles, since the Basic design is identical for doors or windows that open only by rotation and for those that are opened by rotation and tipping;

- reduction of the number of operations of pre-assembled required for tilt handles and rotation;

- a single security lock device against false maneuvers, the sliding plate is the same for all the handles and, if necessary, can be applied to fallebas, even on site, simply and quickly and without using any tool.

Both the tooth and the flexible appendix are exemplary embodiments of the means for fixing the plate sliding to the handle, therefore it is obvious that they can be adopted equivalent fixing means without thereby reducing the effectiveness of the invention.
