Description

Title of the invention: Handle for windows or French doors

[0001] The present invention relates to a handle for window frames, and more particularly to a handle of the type provided, in particular, for use on windows and / or French doors.

[0002] The handles commonly known in the industry as "cremone" handles are used to control the opening mechanisms of windows and French doors and are characterized by a 90° notched positioning. A particularly popular type of this handle is the one that contains the anchoring and positioning system inside the handle body itself; in this way, the handle is devoid of the base anchoring it to the window, with a significantly less impact on the appearance, and this is therefore preferable since it can be adapted to several models and types of window frames.

[0003] Handles of this type are described for example in patent applications EP4030021, EP3392435.

[0004] These handles, however, present a number of operational problems, particularly due to the fact that the notched positioning system is arranged in a small space, such as that which may be available inside the handle body.

[0005] The object of the present invention is to propose a window handle for window frames which overcomes the problems of known handles, while retaining its advantageous characteristics and at the same time representing a preferable variant in terms of aesthetics and technical advantages.

[0006] Another object of the handle according to the invention lies in the fact that it is structurally simple and therefore less likely to break and with lower production and maintenance costs compared to known handles.

[0007] These objects, as well as others, are reached by the handle according to the invention, the essential characteristics of which are defined below. Other important characteristics are also defined.

[0008] The characteristics and advantages of the handle according to the present invention will become clearer from the following description of its embodiment, proposed by way of non-limiting example with reference to the accompanying drawings, in which:

[0009] [Fig.1] Fig.1 is a cross-sectional view of a handle according to the invention, installed on a part F of a window frame;

[0010] [Fig.2] Fig.2 is an exploded view of the handle of Fig.1; and

[0011] [Fig.3] Figures 3 and 4 represent two different types of handle assemblies on the window frame, according to an orthogonal arrangement ([Fig.3]) or according to a 45° arrangement ([Fig.4]).

[0012] [Fig. 4] Figures 3 and 4 represent two different types of assemblies of the handle on the window frame, according to an orthogonal arrangement ([Fig.3]) or according to a 45° arrangement ([Fig.4]).

[0013] As shown in the figures, the handle 1 consists of a gripping part 10 which is intended to be grasped by a user in order to move the handle, when opening or closing the window frame (shown only in its part F in the images) to which the handle is connected, in an operational manner.

[0014] The handle further comprises a body 11 arranged in continuity with the gripping part in an arrangement curved relative to the latter.

[0015] In particular, the body 11 of the handle is considered to be arranged along its own longitudinal axis X' which, in use, can be arranged parallel to the ground or perpendicular to the window frame.

[0016] The body 11 defines a housing 2 for a group of elements to anchor the handle to the window frame and a group of elements to operate the mechanism to open and / or close the window frame. The housing 2 provides a front portion 20 adapted to face the window frame and to contain at least the elements to be fixed to the frame, and a rear portion 21, arranged further back towards the interior of the housing 11, adapted to house at least the operating elements.

[0017] The group of elements for anchoring the handle 1 to the window frame includes an anchoring base 3, which has means for anchoring the handle to the window frame. These anchoring means include, for example, through holes 31 for the screws 32 to be fixed to the frame profile F.

[0018] The holes 31 are arranged along their own longitudinal axis X'.

[0019] To this end, corresponding holes 320 are present in the window frame F for inserting the screws 32. The holes 320 can be made at 90° to each other and orthogonally, i.e. on the XY axes of a Cartesian frame oriented with respect to the ground, so that the X axis is parallel to the ground and the Y axis is perpendicular to the ground, or they can be made at 45° with respect to this frame (see in particular Figures 3 and 4).

[0020] The anchoring base 3 is formed so that it can be positioned inside the housing 2, and in particular the front part 200. Preferably, but not limited to, the anchoring base 3 has a substantially cylindrical shape and extends around its own longitudinal axis X'. The anchoring base 3 also has a central longitudinal through hole 30.

[0021] A sleeve 4 is coupled to the anchoring base, which has a central body 40 on which is formed a longitudinal through hole 400, which is arranged, during assembly, coaxially with respect to the central hole 30 of the anchoring base 3, along the longitudinal axis X'. The sleeve 4 further has a perimeter ring 41 which is rotationally coupled with the inner wall 200 of the part 20 of the housing 2.

[0022] The socket 4 preferably has, but is not limited to, a substantially cylindrical shape, extending around the longitudinal axis X'.

[0023] In addition, the through hole 400 of the socket 4 and the hole 30 of the anchor base together define a through hole 5 to accommodate a sleeve 6 arranged longitudinally.

[0024] The sleeve 6 has a longitudinally elongated central portion 61 and is free to rotate in the seat 5 relative to the longitudinal axis X'. The sleeve 6 also has an enlarged head 62, which abuts against the base 3 through the bushing 4, for axial sealing of the handle in use. The sleeve 6 then has a tenon 63 with flat walls (for example, but not limited to, a substantially square transverse area) intended to be connected by engaging with the body 11 of the handle and in particular with the rear portion 21 of the housing 2.

[0025] The sleeve 6 further includes a central longitudinal through hole 64 to contain an operating pin 7 of the window frame opening / closing mechanism.

[0026] In addition, the sleeve 6 further includes a hole 65 arranged transversely with respect to the longitudinal axis X' for the passage of an adjusting screw 66 which locks the mutual position between the handle body 11, the sleeve 6 and the operating pin 7. A hole is also opened on the handle body 11, which corresponds to the hole 65 during assembly for the passage of the adjusting screw.

[0027] A washer 8 is then provided which is arranged, during assembly, in the position located furthest inside the front part 20 of the housing 2. The washer 8 includes appendages 81 which engage, during assembly, with suitable notches 200a made on the inner wall 200 of the front part 20 of the housing, which results in a fixed engagement between the washer and the handle body.

[0028] The notches 200a are preferably, but not limited to, arranged at 45° to each other.

[0029] The appendages 81 are even in number and are arranged in an orderly manner around the circumference of the washer.

[0030] In addition, the notches are preferably, but not limited to, 8 in number. In one embodiment, the notches are 4 in number.

[0031] The number of appendages 81 depends on the number of notches. In the case of eight notches, you will have four appendages, in the case of four notches, you will have two appendages.

[0032] In the case of the solution with four appendages 81, they are arranged at 90° to each other.

[0033] The washer 8 also has a central longitudinal hole 80 for the passage of the sleeve 6, said hole 80 defining, with said hole 30 and said hole 400, said seat 5.

[0034] Further details of the technical solution are provided, as the anchoring base 3 also has seats 33, each for housing, in a longitudinal arrangement, respective notched positioning means 9. Such means include a spring 90 supporting a ball 91 at its head. Consequently, the spring arranges itself longitudinally, that is, along the longitudinal axis X' of the handle body 11, exerting a thrust force on the ball 91 directed precisely along this longitudinal axis.

[0035] The assembly between the sleeve 4 and the base 3 is obtained by means of a notched engagement of the first notched engagement means 42 of the sleeve with second notched engagement means 34 of the base 3.

[0036] The notched engagement between the first 42 and second 34 engagement means implies not only the stable engagement between the sleeve 4 and the base 3, but also the correct preload of the spring 90 which then acts, by means of the ball 91, by pushing on the appropriate housings 82 made on the washer 8.

[0037] In a preferred solution, the notched positioning means 9 are of 2 or 4 number, arranged circumferentially and spaced at equal distances.

[0038] The rotation of the gripping part 10, as well as the actuation of the handle when opening / closing the window frame, causes the washer 8 to rotate inside the housing 2; the rotation of the washer causes the balls 91 to be pushed in the opposite direction to the return action, forcing the balls 91 out of their respective housings 82 and thus causing their longitudinal retraction with the additional compression of the springs 90. When the rotation of the gripping part is finished, the balls 91 return to their corresponding housings in the washer, again blocking the rotation.

[0039] The dwellings are preferably, but not limited to, 4 in number, and are mutually arranged at 90°.

[0040] Positioning the notches 200a at 45° allows the washer to be placed in the position corresponding to the balls arranged on the base. In fact, with reference to Figures 3 and 4, it can be noted that assembling the base in an orthogonal arrangement ([Fig.3]) or at 45° ([Fig.4]) also results in the washer being placed in an orthogonal arrangement ([Fig.3]) or rotated at 45° ([Fig.4]).

[0041] The described solution thus introduces a simplification of construction compared to known handles. For example, the longitudinal, rather than transverse, arrangement of the notched positioning means, as in known solutions, allows for a more compact yet functional structure and mechanism. This increased compactness allows all the kinematic elements to be contained within the handle body, reducing the overall size of the handle. Furthermore, the washer is a single piece, which nevertheless allows the handle to be mounted on any type of window frame, and therefore universally on orthogonal or 45° fixings to the window frame.

[0042] The present invention has been described herein with reference to its preferred embodiments. It is anticipated that other embodiments may exist and relate to the same subject matter of the invention, all falling within the scope of protection of the claims indicated below.
