[0022] In some embodiments, the number of the snap-fit ​​positioning devices is two or four, arranged circumferentially and at equal intervals.

[0023] In some embodiments, the sleeve is provided with a hole transverse to the longitudinal axis for inserting a retaining screw to secure the sleeve and the operating pin within the body of the handle. Attached Figure Description

[0024] The features and advantages of the handle according to this utility model will become more apparent from the following description of embodiments thereof, which are provided by way of non-limiting example with reference to the accompanying drawings, wherein:

[0025] Figure 1 This is a cross-sectional view of the handle according to the present invention, which is installed on the window frame portion F;

[0026] Figure 2 yes Figure 1 Exploded view of the handle; and

[0027] Figure 3 and Figure 4 It shows the arrangement according to orthogonal arrangement ( Figure 3 Or arranged according to 45° ( Figure 4 Two different types of assemblies for the handles on the window frame. Detailed Implementation

[0028] As shown in the figure, the handle 1 includes a handle 10, which is intended to be gripped by the user to move the handle during the action of opening or closing the window frame to which the handle is operably connected (shown only in part F of the window frame in the figure).

[0029] The handle also includes a body 11, which is arranged in a curved manner relative to the handle and is continuous with the handle.

[0030] Specifically, 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.

[0031] The main body 11 defines a housing 2, which includes a set of components for anchoring a handle to a window frame and a set of components for operating a mechanism to open and / or close the window frame. The housing 2 is provided with a front portion 20 and a rear portion 21, the front portion 20 being adapted to face the window frame and containing at least the components to be fixed to the frame, and the rear portion 21 being arranged further inward at the rear of the housing 11 and adapted to accommodate at least the operating components.

[0032] The component assembly for anchoring 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, channel holes 31 for screws 32 to be fixed to the frame profile F.

[0033] Hole 31 is arranged along its own longitudinal axis X'.

[0034] For this purpose, the window frame F is provided with corresponding holes 320 for inserting screws 32. The holes 320 can be arranged at 90° to each other and orthogonally, that is, on the XY axes of a Cartesian coordinate system oriented relative to the ground, such that axis X is parallel to the ground and axis Y is perpendicular to the ground; or they can be arranged at 45° relative to the coordinate system (see details). Figure 3 and Figure 4 ).

[0035] The shape of the anchoring base 3 is designed to allow it to be positioned inside the housing 2, particularly inside the front portion 200. Preferably, but not limited to, the anchoring base 3 has a generally cylindrical shape and extends about its own longitudinal axis X'. The anchoring base 3 also has a central longitudinal through hole 30.

[0036] The bushing 4 is connected to the anchoring base. The bushing 4 has a central body 40 with a longitudinal through hole 400 formed therein. During assembly, the through hole 400 is arranged coaxially with the central hole 30 of the anchoring base 3 according to the longitudinal axis X'. The bushing 4 also has a peripheral flange 41, which is rotatably connected to the inner wall 200 of part 20 of the housing 2.

[0037] Bushing 4 preferably, but not limited to, having a basic cylindrical shape, extends around the longitudinal axis X'.

[0038] In addition, the through hole 400 of the bushing 4 and the hole 30 of the anchoring base together define a through hole 5 for accommodating the longitudinal arrangement of the sleeve 6.

[0039] The sleeve 6 has a longitudinally elongated central portion 61 and is free to rotate within the seat 5 relative to the longitudinal axis X'. The sleeve 6 also has an enlarged head 62 that abuts against the base 3 via a bushing 4 for axial sealing of the handle during use. The sleeve 6 then has a shank tongue 63 with flat walls (e.g., but not limited to a generally square cross-section) for engaging connection within the handle body 11, particularly within the rear portion 21 of the housing 2.

[0040] The sleeve 6 also includes a longitudinal central through hole 64 for receiving the operating pin 7 of the window frame opening / closing mechanism.

[0041] In addition, the sleeve 6 includes a hole 65 arranged transversely to the longitudinal axis X' for a fixing screw 66 to pass through, which locks the relative positions of the handle body 11, the sleeve 6, and the operating pin 7. The handle body 11 also has a hole that mates with the hole 65 during assembly for the fixing screw to pass through.

[0042] Then, a washer 8 is installed, which is positioned at the innermost part of the front portion 20 of the housing 2 during assembly. The washer 8 includes an attachment 81, which engages with a suitable groove 200a formed on the inner wall 200 of the front portion 20 of the housing during assembly, thereby forming a fixed engagement between the washer and the handle body.

[0043] The grooves 200a are preferably, but not limited to, arranged at 45° relative to each other.

[0044] The number of Attachments 81 is even, and they are arranged in an orderly manner around the circumference of the washers.

[0045] Furthermore, the number of grooves is preferably eight, but not limited to this. In one embodiment, the number of grooves is four.

[0046] The number of attachments 81 is related to the number of slots. With 8 slots, you will have 4 attachments; with 4 slots, you will have 2 attachments.

[0047] In the case of a solution with four attachments 81, these attachments will be arranged at 90° relative to each other.

[0048] The washer 8 also has a central longitudinal hole 80 through which the sleeve 6 passes, the hole 80 together with the hole 30 and the hole 400 defining the seat 5.

[0049] Further examining the details of the technical solution, the anchoring base 3 also has seats 33, each seat for accommodating a corresponding snap-fit ​​positioning device 9 arranged longitudinally. This device includes a spring 90 supporting a ball 91 at its head. Thus, the spring, arranged longitudinally itself, i.e., according to the longitudinal axis X' of the handle body 11, applies a thrust to the ball 91 precisely aligned with that longitudinal axis.

[0050] The assembly between the bushing 4 and the base 3 is achieved by the snap engagement of the first snap engagement device 42 of the bushing and the second snap engagement device 34 of the base 3.

[0051] The snap-fit ​​engagement between the first engagement device 42 and the second engagement device 34 involves not only a stable engagement between the bushing 4 and the base 3, but also the proper preloading of the spring 90, which is then pushed by the ball 91 against the appropriate receiving hole 82 made on the washer 8.

[0052] In the preferred solution, the number of snap-fit ​​positioning devices 9 is 2 or 4, arranged circumferentially and at equal intervals.

[0053] Rotation of handle 10 actuates the handle when opening / closing the window frame, causing washer 8 to rotate inside housing 2. The rotation of the washer pushes ball 91 in the opposite direction to the spring's action, forcing ball 91 out of its corresponding receiving hole 82, thus causing ball 91 to retract longitudinally as spring 90 is further compressed. When the rotation of the handle is complete, ball 91 will re-enter the corresponding receiving hole in the washer, preventing rotation again.

[0054] The number of receiving holes is preferably, but not limited to, four, and they are arranged at 90° to each other.

[0055] The 45° positioning of the groove 200a allows the washer to be placed in a position corresponding to the ball arranged on the base. In fact, see... Figure 3 and Figure 4 It can be noted that the base is orthogonal ( Figure 3 ) or 45° Figure 4 The assembly arrangement also results in the washers being orthogonal ( Figure 3 ) or rotate 45° ( Figure 4 The arrangement is as follows.

[0056] Therefore, the described solution introduces a simplification in construction compared to known handles. For example, the longitudinal arrangement of the snap-fit ​​positioning device (rather than the transverse arrangement according to known solutions) results in a more compact and functional structure and mechanism. The increased compactness allows all moving elements to be kept within the handle body, thus reducing the overall size of the handle. Furthermore, the washer is a one-piece design, yet allows the handle to be mounted on any type of window frame, and is therefore typically mounted to the window frame in an orthogonal or 45° attachment manner.

[0057] This invention has been described with reference to preferred embodiments. It should be understood that other embodiments related to the same inventive core may exist, all of which fall within the protection scope of the following claims.
