• the present invention relates to a handle. More in particular, the ' present invention relates to a handle for leaves, preferably sliding leaves. More in particular, the present invention relates to a handle for leaves, preferably sliding leaves, provided with a control member for controlling a locking device.
• This rack can for instance be connected to one or more rods for movement of a chain or a plurality of chains of a multipoint locking device.
• the "VERSUS" handle is extremely compact and simple to install, but it presents two disadvantages: firstly, the “toothed lever + rack” control mechanism is not universal and can only be used in combination with a limited number of closing devices, typically manufactured by SOTRALU; moreover, the need to pre-install economically the control mechanism and the anchoring device for anchoring to the leaf, through a permanent assembly solution, together with the impossibility of decoupling and subsequently recoupling these components without damaging them, and thus leaving no trace of this operation, makes operations to paint and customise the external appearance of the handle impossible, both prior to the first installation and for overhauling after a more or less prolonged use.
• a handle for sliding leaves provided with a control member for controlling the respective locking device, which is characterised by the possibility of being completely customised and by being extremely simple to construct and install, could allow to overcome the typical drawbacks of the prior art described above and to define a new standard for these types of handles.

• the collar 230 presents an internal diameter exceeding any transverse dimension of the pin 51 and both the collar 230 and the respective cylindrical fourth seat 18 are coaxial with the axis 215.
• the presence of the collar 230 and of the respective fourth seat 18 is not strictly necessary for correct operation of the control device 20, as the coupling device 10 is sufficient to maintain the lever 21 stably coupled to the base 11 in a freely rotatable and axially fixed manner; on the other hand, the presence of a further rotating coupling between the collar 230 and the respective fourth seat 18 allows greater stability to be given to the coupling between the lever 21 and the base 11 and also allows the strains acting on the first and second couplings 40 and 41 to be reduced, so that they can benefit from a greater operating life.

• the handle 1 presents at least one signalling unit 60 for signalling the operative position of the locking device 50 so that each user can, observing the handle 1 with a simple glance, realise the effective current operative position of the respective leaf 2, and in particular whether the lever 21 is suitable to maintain the locking device 50 in the respective closing or opening position.
• This signalling unit 60 can, by way of example and without in any way limiting the present invention, be produced by at least one label 61 associated with a respective operative position of the lever 21 inside the first seat 14.

• each anchoring device 30 comprises a cap 32, axially perforated, shaped similarly to a rivet 32, and therefore indicated hereafter with this term.
• Each anchoring device 30 also comprises a body 34 preferably, but without limitation, presenting an intermediate third portion 37, bilaterally delimited by respective end fourth portions 38 and presenting with respect thereto a cross section of reduced dimensions.
• each body 34 is substantially shaped similarly to an hourglass and presents a thread at the base of a respective fourth portion 38, represented at the bottom with reference to figure 5, to screw couple to a respective rivet 32, which is in turn rigidly connected to the respective flat face 4 and presents a central hole provided with a respective axial thread. Furthermore, each body 34 is stably housed inside a respective fifth seat 33 obtained in the base 11 so that it is not visible from the outside.

• first handle 1 can be coupled to the locking device 50, whilst the second handle 1 may also not be provided with any switching member 21 and therefore act only as a manoeuvring member.
• the handle 1 can comprise a cap 250 which replaces the lever 21 and is suitable to seal the first seat 14 to prevent dust, rain or other external elements from penetrating the handle 1. This could be particularly useful especially in the case in which the second handle 1 is located on a flat face 4 facing an outside environment.
• This process comprises a step of elastically snap coupling the lever 21 to the base 11 so that the lever 21 is freely rotatable and selectively decouplable.
• this step of elastically snap coupling the lever 21 to the base 11 comprises a step of inserting the lever 21 inside the base 11 according to a direction of insertion substantially perpendicular to the axis 215. More in particular, this step of inserting the lever 21 inside the base 11 in turn comprises a step of progressively deforming the wedge- shaped second element 24 of the lever 21 under the action of the second portion 15 of the base 11.
• the step of elastically snap coupling the lever 21 to the base 11 can be preceded by a step of separately painting the lever 21 and the assembly of the base 11 and of the handgrip 12 to obtain complete customisation of the aesthetic characteristics of the handle 1.
• This step of painting can preferably be implemented using the industrial powder painting technique and therefore comprise the sub-steps of coating the handle 1 with a given powder paint and the subsequent sub-step of baking the handle 1 at high temperature in a specific oven.
• the present method comprises a step of giving stability to the coupling between the lever 21 and the base 11 by means of inserting a pin 51 inside the respective second seat 26; clearly this step can only be performed following the step of elastically snap coupling the lever 21 to the base 11.

• the handle 1 is provided with a base 11 substantially identical to the one described above, but provided with two holes 333 positioned symmetrically and at the opposite sides relative to the switching member 21, and thus to the respective first seat 14, such as the holes 33 visible in figure 2, but positioned at a close distance which substantially approximates 43 mm.

• each hole 336 is accessible frontally from the second end 23 of the lever 21, and is inclined by an angle sufficient to allow easy use of a wrench for tightening the dowels 411 and 412, thus allowing an operator to prevent interferences with the external framework, known and therefore not shown, of the leaf 2 or with a glass sheet, known and therefore not shown, installed on the leaf 2.
• this given angle has a width of 7°.
• the anchoring device comprises caps 415 and 416 which are substantially identical to one another and mushroom-shaped, in order to be housed, respectively, in the holes 336 and avoid access to the dowels 412.
• each cap 415 and 416 presents a substantially hemispherical head 417, suitable to act as an angular abutment for the lever 21.
• the caps 415 and 416 are made of plastic material of clashing colours: the cap 415 is made of red plastic material, and the cap 416 of green plastic material.
• each head 417 is suitable to provide information about an opening or closing operative position of the lever (21) . Therefore, the use of bushes 400 shaped as described above allows the respective screws 405 to be coupled rigidly to the base 11 with the respective longitudinal axis being positioned coaxially with the respective hole 333. It should be specified that the two holes 333 and 336 are substantially communicating.

Therefore, the handle 1, in both the versions described herein, can be completely customised using common industrial painting techniques, for instance powder painting, without needing to perform subsequent operations prior to assembly of the lever 21, and therefore without jeopardising correct operation of the control device 20 associated with the " handle 1 and of the respective anchoring devices 30 or 330.
