Description

HANDLE FOR DOORS AND WINDOWS AND WINDOW OR ASSOCIATED DOOR

D E S C R I P C I O N OBJECT OF THE INVENTION

The present invention relates to a door and window handle and can be included in the technical sector of the manufacture of windows or doors and their hardware. More specifically, the object of the invention is a handle that encompasses a series of relative improvements that allow hiding all the elements thereof except the handle itself, which avoids the risk of user contact with the base of said handle when it leads to After opening or closing said handle, it also favors the aesthetics of the handle, directing it towards minimalism and corrects existing gaps or wear that occur in the direction of the handle drive shaft.

BACKGROUND OF THE INVENTION

Today, the market of doors and windows is characterized by having, in its closing systems, handles and cremmon which usually include a manual-operated handle to transmit the turning movement to the internal mechanisms of the system, and be transmission boxes in the case of handles, transmission covers in the case of creams, etc.

The turning movement transmitted by the handle is transformed into translational movement by mechanisms that can be both within the profile in the form of a transmission case, and at the base of the cremone-shaped handle, both with rack and pinion systems. Patents CH485099, DE1815345, DE3445170A1, EP0446566 disclose such systems. However, the handles that do not have a base that are currently known, are limited to a certain number of window profiles, since in the different European channel profiles where said handles are housed, the distance between the center of the channel where they are it is housed the handle mechanism and the profile wing that defines the outer part of the door or window leaf, it varies, so that sometimes said known handles cannot be mounted on a profile anymore existing.

In the same way, the handles that present the external base to the profile, have the disadvantage that the user contacts the base of said handle when carrying out the opening or closing of said handle, making said operation uncomfortable, said base also being little appropriate if you want to achieve a minimalist aesthetic. In addition, these mechanisms are very complex, with production times and high material costs.

The Utility Model with publication number ES1 146109U of this same applicant is also known, which discloses a door and window handle comprising a handle, a transmission mechanism arranged inside the door or window leaf profile, and a movable part arranged between a wing of the leaf profile that defines the outer part of the door or window leaf and the transmission mechanism for adapting the handle to different widths of the door or window leaf profile.

However, the previous handle, although adaptable to variations in distance between the center of the channel where the handle mechanism is housed and the profile wing that defines the outside of the door or window leaf, does not allow absorption the variations in the thickness of the wing of said profile or the clearances that could exist in the direction of the axis of drive of the handle, in addition to not being able to compensate for the wear of the elements that make up the handle, so that due to use, the handle it would be separated from the profile wing that defines the outer part of the door or window leaf, causing a possible failure over time due to a greater actuation arm.

The object of this invention is to provide a solution to all the above-mentioned problems, preventing the base of the handle from being outside the profile and allowing said handle to adapt to all European-type profiles and existing gaps or wear which occur in the direction of the handle drive shaft. DESCRIPTION OF THE INVENTION

The present invention relates to a door and window handle whose base is arranged inside the door or window leaf profile, where said handle can be adapted to all European type profiles.

The door and window handle comprises a handle, a transmission mechanism arranged inside a door or window leaf profile and a movable part disposed between a wing of the leaf profile defining the outer part of the leaf of the door or window and the transmission mechanism that allows the adaptation of the handle to different widths of the profile of the leaf of the door or window.

This is due to the fact that the movable part disposed between the leaf of the door or window and the transmission mechanism is movable in a direction defined by the axis of operation of the handle allowing to vary the existing height between the center of a channel of the profile of the door or window leaf where the handle transmission mechanism is housed and the wing of said door or window leaf profile.

The handle comprises means for fixing the handle to the movable part that contribute with elastic means to absorb existing gaps or wear that occur in the direction defined by the axis of actuation of the handle.

The handle comprises regulating means that carry out the displacement of the movable part in the direction defined by the drive axis of the handle. The handle comprises a square that transmits the movement of rotation of the handle to the transmission mechanism, which transforms the movement of rotation of the handle into a movement of translation of a fault arranged by the interior of the leaf of the door or window for the release or fixing it to the door or window frame. Preferably, the handle comprises a plastic drop that defines the turning positions of the handle.

Preferably, the movable part comprises a retaining part of the means for fixing the handle to the movable part.

PREFERRED EMBODIMENT OF THE INVENTION

Next, the door and window handle of the present invention will be described in detail. The handle comprises a handle (101), a transmission mechanism (108) arranged inside a profile (30) of the door or window leaf and a movable part (06) arranged between the profile (130) of the leaf of the door or window and the transmission mechanism (108) that allows the adaptation of the handle to all European type profiles, the movable part (106) being arranged between the profile (130) of the door leaf or window and the transmission mechanism (108) movable in the direction defined by the drive shaft of the handle (101), allowing varying the height (A) between the center of a channel (120) of the profile (130) of the leaf of the door or window where the transmission mechanism (108) and a wing (140) of said profile (130) of the leaf that defines the outer part of the leaf of the door or window is housed. The transmission mechanism (108) comprises a pinion (190) which in turn comprises a hole (191) for the transmission of the movement of the lever (101) to the transmission mechanism (108). The channel (120) of the profile (130) of the leaf of the door or window where the transmission mechanism (108) is housed comprises a recess (189) for the insertion of the transmission mechanism (108) and the movable part (108).

The handle further comprises fixing means (153, 154) of the handle (101) to the movable part (108) that contribute with elastic means (155), preferably a pressure spring arranged in a cylindrical cavity (188) of the inside the handle (101), to absorb existing gaps or wear that occur in the direction defined by the handle drive shaft (101), where said elastic means (155) are also attached to a plastic bushing ( 104) defining the turning positions of the handle (101).

The handle comprises a base (105) that allows the handle (101) to be fixed on the profile (130) of the door or window leaf, where said base (105) comprises antagonistic protuberances (109) of a die cut (1 14 ) present in the wing (140) of said profile (130) of the sheet. The base (105) comprises lateral projections (170) that compensate for the lateral clearances in the adjustment of the base (105) with the punching (1 14) of the wing (140) of the profile (130) of the leaf.

Said plastic bushing (104) comprises emptied (164) antagonists of projections (167) arranged in the base (105), where the relative position of the projections (167) of the base with respect to the recesses (164) of the plastic bushing defines the turning positions of the handle (101). Preferably, the plastic bushing (104) comprises four hollows (164), 90 ° equiespaced antagonists of four projections (167) 90 ° of the base (105), defining the discrete positions of the handle (101) from 90 ° to 90 °. The base (105) also comprises cavities (168) for housing the screw heads (103) and preventing them from interfering with the plastic bushing (104).

The relative rotation of the plastic bushing (104) with respect to the base (105) causes the emptyings (164) of the plastic bushing (104) to slide over the projections (167) of the base (105), thus compressing the spring even more pressure (155). Preferably, both the projections (167) and the recesses (164) are curved, so that, together with the force exerted by the pressure spring (155) on the plastic bushing (104), it makes the handle (101) tend to be placed in the positions where protrusion (167) and emptying (164) coincide, which are the positions where the pressure spring (155) applies less force, and where the handle (101) describes a relative rotation of 90 °.

The handle comprises adjustment means, preferably screws (103), which carry out the displacement of the movable part (106) in the direction defined by the drive shaft of the handle (101). Preferably, said regulating means also act as fixing means of the movable part (106) and of the base (105) to the profile (130) of the leaf of the door or window because the screws (103) are threaded in threaded holes (196) of the movable part (106).

The movable part (106) comprises protrusions (1 10) antagonists of holes (11) present in the transmission mechanism (108), for guiding the movement of the movable part (106) with respect to the transmission mechanism (108) . The movable part (106) further comprises protrusions (184) that face each other and are anchored to the inner wall of the wing (140) of the profile (130) of the sheet when the screws (103) are tightened. The means of regulation.

The handle comprises a square (107) that transmits the rotation movement of the handle (101) to the transmission mechanism (108), which transforms the movement of rotation of the handle (101) in a movement of translation of a failure (not shown) arranged inside the leaf of the door or window for the release or fixation thereof to the frame of the door or window. The handle comprises means for fixing the handle (101) to the square (107), where said fixing means are preferably the outer surface of the square and an inner surface of the handle that come into contact and allow the pressure joining of the handle (101) and the square (107). The square (107) comprises a hole (187) where the fixing means (53, 154) of the handle (101) are housed to the movable part (108), which in this preferred embodiment are a spring (153 ) which is attached to a pin (154), so that when the handle (101) together with the square (107) is inserted through the movable part (106) overcoming the resistance of the pressure spring of the elastic means (155), the pin (154) retains the handle (101) attached to the movable part (106), fixing the assembly formed by the square (107), the plastic bushing (104), the base (105) and the spring of pressure of the elastic means (155) to the movable part (106). This is possible because the movable part (106) comprises a retention part (161) and a fixing plate (181) for fixing the retention part (161) to a hole (183) of the movable part ( 106), preferably by riveting. The retaining part (161) comprises a semi-cylindrical radial recess (179) in which the pin (54) of the fixing means (153, 154) of the handle (101) is housed. The retaining part (161) comprises an axial recess (180) antagonist of an axial shoulder (182) of the movable part (06) that determines the mounting position of the retaining part (161) in the movable part (106) . The axial projection (182) of the movable part (06) is breakable due to the operation of the handle, so that the retention part (161) rotates freely with respect to the movable part (06).

The plastic bushing (4) and the retaining part (161) comprise essentially square holes (165, 177) for the coupling of the square (107), which is also coupled to the hole (191) of the pinion (190) of the mechanism transmission (108). In this way, once the handle (101) is mounted together with the square (107) and the plastic bush (104), the force exerted by the pressure spring (155) outwards keeps the handle (101) in position, corrects possible clearances, compensates for the wear of the plastic bush (104) and the thickness of the wing (140) of the profile (130) of the blade, in addition to allowing varying the level (A) between the center of a channel (120) of the profile (130) of the leaf of the door or window where the transmission mechanism (108) and a wing (140) of said profile (130) of the leaf that defines the outer part of the leaf of the door or window. Another essential function of the pressure spring (155) is to maintain, as firmly as possible, the plastic bush (104) glued to the base (105), matching the emptyings (164) of the plastic bush (104) with the protrusions (167) antagonists arranged in the base (105).

The handle comprises a washer (157) disposed in the circumferential space between the base (105) and a first section (176) of the cylindrical cavity (186) of the handle (101) that prevents gaps between the base (105) and the cylindrical cavity (186) and guarantees a correct rotation of the lever assembly (101), pressure spring (155), plastic bush (04) with respect to the base (105). Preferably, the washer (157) is made of a low friction plastic material.

The plastic bush (104) comprises circumferential recesses (192) attachable in circumferential projections (193) of a second section (194) of the cylindrical cavity (186) of the handle (101) for guiding said plastic bush (04) ), avoiding gaps between the handle (01) and the plastic bushing (104).
