Definitions

• the present invention relates to a handle for doors and windows in the technical field of manufacturing windows or doors and their fittings. More specifically, the object of the invention is a handle that encompasses a series of relative improvements that allow the frontal coupling of a base part together with a handle and a turning axis to a profile wing and to a counterplate housed inside the profile. .
• the configuration of the handle allows the use of said handle in a wide range of profiles of different widths and types of openings, without penalizing the operation or minimalist aesthetics of the handle, especially in PVC profiles.
• the correct positioning of the axis of rotation is ensured in an initial situation of clipping.
• Manually operated handles are currently known to transmit the turning movement to the internal mechanisms of the system, whether they are transmission boxes in the case of handles, transmission sleeves in the case of cremones, etc.
• the turning movement transmitted by the handle is transformed into translational movement by mechanisms that can be both inside the profile in the form of a transmission box, and in the base of the handle in the form of a cremone, normally by means of rack and pinion systems.
• handles that do not have a base are limited to a certain number of window profiles, since in the different European channel profiles where these handles are housed, the distance between the center of the channel where they are The mechanism of the handle and the wing of the profile that defines the outer part of the door or window leaf is housed, varies, so that sometimes said known handles cannot be mounted on an already existing profile.
• the handles that present the base external to the profile present the inconvenience that the user contacts the base of said handle when he carries out the opening or closing of said handle, making said operation uncomfortable, also resulting in said base little appropriate if you want to achieve a minimalist aesthetic.
