Definitions

  • the present invention relates to a lock for doors and/or windows.
  • the invention relates to a lock provided with a control of the axial thrust type, which converts the thrust or traction movement into a rotation movement applied to the handle follower.
  • the lock system of the invention is further installable on all locks using the classic rotating lowering system of the handle, simply by replacing the handle follower.
  • the lock of the invention has the advantage of allowing complete freedom in relation to the form of handle to be used, as the handle need only receive thrust or traction forces and no longer rotation forces in a vertical plane.
  • the present invention is advantageously applied in the sector of doors, windows and installations in general and in particular in the sector of closing and opening means thereof.
  • the doors or windows used for closing accesses to rooms of a building are provided with locks provided with a latch and/or a bolt.
  • an installation is usually formed by a support frame mounted at the opening of a wall and comprising two opposite vertical uprights, or jambs, and a crossbar element arranged between the vertical uprights transversally thereto, and by a wing, being a door or a window, rotatably connected to an upright of the support frame.
  • the lock comprises a box body inserted in a special housing of the wing; in particular, the box body is provided with a latch and/or a bolt slidably mobile between a retracted configuration inside the box body and an extracted configuration from the box body for engaging in a corresponding latch-hole and/or bolt-hole realised on one of the vertical uprights of the installation.
  • the latch With particular reference to the latch, it is provided with an inclined surface able to abut and slide on an edge of a strike plate installed on the jamb, said inclined surface thus actuating the retraction of the latch inside the box body during the closing step of the door.
  • the latch is opposed by a spring which tends to keep it in the normally-extracted configuration from the box body; therefore, after having abutted with the edge of the strike plate and having been retracted into the box body up to the exceeding of the above-said edge of the strike plate, the latch is returned into the extracted configuration by the spring, so that it can insert in the latch-hole fashioned on the jamb of the installation and thus actuate the closing of the installation.
  • a lock for doors and/or windows according to the preamble of claim 1, in particular in which a translation movement of a control member is converted into a rotating movement of an actuator member by effect of the sliding of a cam follower element inside a cam, is disclosed in document GB2498340A .
  • the technical task underpinning the present invention is to disclose a lock for doors and/or windows which obviates the drawbacks of the known art as mentioned above.
  • an aim of the present invention is to provide a lock for doors and/or windows which is alternative to those at present on the market. Still more in particular, an aim of the present invention is to provide a lock able to guarantee a greater freedom in relation to the form of the handle to be used.
  • a further aim of the present invention is to provide a lock for doors and/or windows which has a simple and immediate operation.
  • a further aim of the present invention is to provide a lock for doors and/or windows which has modest size and weight.
  • a further aim of the invention is to realise a lock that is reliable and resistant to repeated forces, during the step of opening and closing the installation.
  • reference numeral 30 denotes in its entirety a lock for doors and/or windows and for installations in general.
  • the lock 30 comprises at least a box body 31 that in turn comprises a closing element 33, for example a bolt, a hook or a chain, mobile at least between an extracted configuration from the box body 31 and a retracted configuration in the box body 31.
  • a closing element 33 for example a bolt, a hook or a chain
  • an actuator member 35 is used that is kinematically connected to the closing element 33.
  • the actuator member constitutes the handle follower which is connected to the closing element 33 by means of kinematic mechanisms that are neither further illustrated or described as they are of known type.
  • the actuator member 35 is able to activate the displacement of the closing element 33 between the extracted and retracted configurations, enabling the closing element 33 to project or retract with respect to a frontal plate 32 of the lock 30.
  • the actuator member 35 is mobile in rotation between at least two operating positions which respectively correspond to the above-said extracted and retracted configurations of the closing element.
  • the closing element 33 of the lock 30 is mobile in translation between said extracted and retracted configurations.
  • the translation direction of the closing element 33 is substantially transversal to the rotation axis of the actuator member 35.
  • Said closing element 33 is preferably a bolt or a latch.
  • the closing element of the lock is mobile by rotation between said extracted and retracted configurations, for example it can comprise a rotating element of the hook type.
  • the actuator member 35 comprises a hollow body 34, preferably cylindrical, subject to rotation about a transversal axis with respect to the sliding direction of the closing element 33; in particular said hollow body 34 defines a handle follower kinematically connected to the closing element 33.
  • the hollow body 34 of the actuator member 35 is intercepted by a control member 37 kinematically connected to said actuator member 35 for controlling rotation thereof.
  • the control member 37 is mobile along a translation direction between at least two operating positions which respectively correspond to the operating positions of the actuator member 35, which in turn correspond to the extracted and retracted configurations of said closing element 33.
  • the control member 37 has an elongate shape, preferably cylindrical, having dimensions such as to slide inside the actuator member 35; the control member is solidly constrained to at least a cam 38 having an extension that is at least partly helical.
  • the actuator member 35 preferably has two cams 38 having a straight extension (for a first portion) and partly helical (for a second portion) arranged opposite one another relative to the rotation axis of the control member 37.
  • the cam 38 (or cams 38 if there is more than one) is slidably intercepted by a cam follower element 36 solidly constrained to the actuator member 35, so that the translation movement (see the arrows in figure 5 ) of the control member 37 is converted into a rotating movement of the actuator member 35 by effect of the sliding of the cam follower element 36 inside the cam 38.
  • the cam follower element 36 is constituted by at least a hemisphere, preferably two hemispheres.
  • the hemispheres are fashioned on the hollow body 34 which defines the handle follower and are facing towards an inside of the hollow body, being further arranged frontally to one another, i.e. diametrically opposite one another.
  • control member 37 has at least a longitudinal groove 39 that is parallel to the translation direction of the control member 37, preferably two grooves 39.
  • said grooves are arranged opposite one another relative to the rotation axis, alternating with said cams 38 having at least partly helical extensions.
  • control member 37 is associated to two bushings 42, and 44 which enable sliding thereof while preventing rotation at the same time so that said cams 38 having an at least partly helical extension impress a rotation on said actuator member 35 by sliding in the cams of the cam follower elements 36 solidly constrained to the actuator member 35 ( figures 4 and 5 ).
  • first bushing 42 provided with a first tooth 43 is fixable to the box body 31, and a second bushing 44, provided with a second tooth 45 and also fixable to the box body 31 on the opposite side to the first bushing 42 with respect to the box body.
  • control member 37 inserts in both the bushings 42, 44, crossing the box body 31 so that both teeth 43, 45 are slidably inserted in said longitudinal groove 39 of the control member 37, so that the control member can carry out linear movements following pressure or traction forces exerted thereon by a user.
  • said bushings 42, 44 are reciprocally fixed and fixed on said box body 31 for maintaining the control member 37 in an engaging condition on the box body 31.
  • the bushings 42 and 44 are preferably reciprocally fixed and fixed on the box body 31 by means of retaining means 46 of the screw type, or similar.
  • control member 37 is associated to elastic means 40, preferably a spring, operatively active on the control member 37 for maintaining the control member 37 in an operating condition normally corresponding to said extracted configuration of the closing element 33.
  • elastic means 40 preferably a spring, operatively active on the control member 37 for maintaining the control member 37 in an operating condition normally corresponding to said extracted configuration of the closing element 33.
  • said elastic means are retained on the control member between a retaining element 41, preferably defined by a disc-shaped head of the control member 37 having greater dimensions with respect to the diameter of the control member 37, and a portion of the bushing 42, so that the elastic element is in a pre-loaded condition.
  • the elastic element 40 is mounted in abutment on the retaining element 41 of the control member 37 and then the control member 37 is inserted in the first bushing 42, and lastly a transversal plug 47 is fitted in the control member 37 for preventing the extraction of the bushing 42, so as to actuate the pre-loading of the elastic element.
  • the length of the travel of the control member 37 corresponds substantially to the distance between the fixing point of the plug 47 to the control member and the retaining element 41.
  • the control member 37 Once the first part of the control member 37 has been assembled, it is inserted in the actuator member 35 and fixed to the box body 31, using the second bushing 44 positioned on the opposite side of the box body. Thereafter, the bushings are maintained in the seating thereof by the fixing means 46, at the same time enabling free translation of the control member 37 in opposition to the elastic means 40.
  • control member 37 By acting on the control member 37, i.e. exerting a pressure or traction force, a translation of the control member 37 is produced, so that the two hemispheres 36, intercepted by the at least partly helical cams 38, transform the translation movement of the control member 37 into a rotation movement of the actuator member 35, enabling the retraction of the closing element 33.
  • the control member 37 is constrained to translate in an axial extension direction thereof, as the teeth 43 and 45 of the bushings 42 and 44 prevent rotation thereof; in this way, the at least partly helical cams 38 are able to exert an angular thrust on the hemispheres 36 and thus impress a rotation movement to the above-said handle follower 34 (i.e. the actuator member 35).
  • a first and a second operating condition is illustrated, where "Y" indicates a translation distance of the control member 37 and "X" indicates the rotation angle of the actuator member 35.
  • the entity of the translation "Y” of the control member 37 and the entity of the angular rotation "X" of the actuator member 35 depend on the amount of the displacement demanded on the closing element 33. For example, to obtain a displacement of 10 mm of the closing element 33 a translation di 6.5 mm is required of the control member 37 and a rotation by 27° of the actuator member 35.
  • Figures from 8 to 12 illustrate in greater detail the control member 37 with the respective at least partly helical cams 38, with the grooves 39 and further illustrate the position of the hemispheres 36 during the axial displacement of the control member 37.
  • FIG 10 a mounted configuration is illustrated, in which the hemispheres 36 of the hollow body 34 insert in the straight portion of the cams 38 in order to be located in a neutral position, as is visible in figure 11 (section B-B).
  • an initial configuration is illustrated, in which the hemispheres 36 are in proximity of the initial part of the helical portion of the cams 38, at an instant preceding the activation of the rotation of the hollow body 34 (which is a part of the actuator member 35).
  • FIG. 12 With reference to figure 12 (section C-C), an operating configuration is illustrated, in which the hemispheres 36 of the hollow body 34 have entered the helical portion of the cams 38, for activating the rotation of the hollow body 34 by the corner indicated by letter "X", so as to determine the displacement of the closing element 33.
  • a first version of the lock of the invention is illustrated (respectively in a frontal view and in section according to two different operating steps), in which the activating of the control member 37 occurs by use of a pair of built-in lever mechanisms 48.
  • the lever mechanisms 48 are operatively active on the control member 37 for moving the control member 37 between at least two operating positions which respectively correspond to the above-mentioned extracted and retracted configurations of the closing element 33; in particular, each of said lever mechanisms 48 is rotatably connected, including indirectly, to the box body 31.
  • a first of said lever mechanisms 48 has a first end that is hinged to the box body 31, a second end that is free and an intermediate portion between said ends that is able to define an abutment for said control member 37, so that, at a nearing movement of the lever mechanism towards the box body 31, the intermediate portion exerts a pressure on the control member 37 causing the control member 37 to translate from the operating position corresponding to the extracted configuration of the closing element 33, to the operating position corresponding to the retracted configuration of said closing element 33.
  • the second of said lever mechanisms 48 which is positioned on the opposite side with respect to the box body 31, has a first end that is hinged to the box body 31, a second end that is free and an intermediate portion between said ends and engaged to the control member 37.
  • the intermediate portion exerts a traction on the control member 37 causing the control member 37 to translate from the operating position corresponding to the extracted configuration of the closing element 33, to the operating position corresponding to the retracted configuration of said closing element.
  • the lever mechanisms advantageously receive only thrust or traction forces and no longer rotation forces in an axis that is perpendicular to the sliding direction of the closing element 33.
  • a second version of the lock of the invention is illustrated (respectively in a frontal view and in section according to two distinct operating steps), in which the activation of the control member 37 takes place by use of a pair of lever mechanisms 49 which are located externally with respect to the surface of the door, differently to the lever mechanisms 48 that are in a built-in position.
  • a third version of the lock of the invention is illustrated (respectively in a frontal view and in section according to two different operating steps), in which the activating of the control member 37 is done by using a pair of grips 50 solidly connected to the control member 37 and positioned on opposite sides with respect to the box body 31, so that, following a pressure action on a first grip or a traction on a second grip, the control member 37 translates from the operating position corresponding to the extracted configuration of the closing element 33 to the operating position corresponding to the retracted configuration of said closing element 33.
  • the lock of the invention offers the possibility to use numerous applicative variants of the thrust or traction movement means of the control member, with the possibility of a wide range of embodiments of the handles, which can built in or external to the door, or a knob with a very wide selection of aesthetic embodiments.
