Definitions

  • the present invention concerns an improved anti-burglary or anti-intrusion handle, adapted to be applied in particular to the inner face of a perimetrical frame of a window or of a door mounted in a room of a building and having safety functions against forced and destructive openings le aperture possibly done from the outside by malicious people who want to sneak into the room.
  • a handle of the type considered herein, defined as "DK” is provided with an always operative anti-intrusion or anti-burglary system performing its function when the shutter, the plate or in general a generic panel to which it is applied closes the room.
  • an anti-burglary "DK" handle belonging to the known art, comprises a front grip at user's availability who accesses it from the inside of a room of a building and is provided with a neck suitable to be axially stably and revolvingly coupled with a linear portion of a perimetrical frame belonging to a panel of a window, a door or a balcony.
  • An anti-burglary handle of known type also includes a polygonal bar which defines a linear axis, is revolvingly coupled with the front grip and is suitable to be partly and frontally inserted into the linear portion of the perimetrical frame from which it protrudes towards the inside of the room by a predefined initial stretch.
  • the locking mechanism which operatively connects the polygonal bar with the front grip in such a way that the locking mechanism on one side, as a result of the handling of the front grip carried out by the user from the inside of the room, allows to transmit a torque to the polygonal bar and, on the other side, prevents any person to transmit a torque from the polygonal bar to the front grip: specifically, the locking mechanism takes a work position, in which the rotation of the polygonal bar and of the front grip integral with it around the linear axis is inhibited, and at least a release position, in which the rotation of the polygonal bar around the linear axis is allowed, caused by the user by rotating the front grip from the inside of the room.
  • some "DK" handles of known type provide a special button available to the user and arranged on the outer surface of the front grip: when necessary, the user presses such a button to position the locking mechanism introduced above in the release position starting from the work position and releases it in order that the locking mechanism resumes the work position.
  • main purpose of the present invention is to provide an improved anti- burglary (or anti-intrusion) handle which allows to keep substantially unchanged, with respect to the traditional handles, the constructive design, the external shape and the aesthetic appearance of the front grip which can be operated by the user to open even only partly and close the room through the generic panel to which the handle is applied.
  • main purpose of the invention is to provide an improved anti-burglary handle in which, contrary to the prevailing prior art, the front grip available to the user presents a global standard and traditional construction concept, substantially equivalent to that one of other not necessarily anti-burglary handles, and does not require a specific and specifically designed production in order to be equipped with an anti-burglary function.
  • a second purpose of the present invention is to provide an improved anti-burglary handle particularly reliable both in the common use of moving the panel which it is associated with and in the anti-burglary function to which it is intended.
  • the improved anti-burglary handle of the invention presents a construction concept simpler than the equivalent handles of the current state of the art with respect to which it is also more reliable in exerting the anti-burglary function and in the transition from the conditions of absolute locking to the conditions of free rotation of the front grip which can be operated by the user and vice versa.
  • the locking mechanism includes graft means which can be operated by actuation means in axial sliding along the linear axis by means of a pressure or traction exerted by the actuation means on the outer surface of the front grip which places the locking mechanism temporarily in the release position, disengaging the graft means and thus allowing rotation of the polygonal bar, and by means of a counterthrust, contrary to the aforesaid pressure or traction, exerted spontaneously, as soon as the actuation means release the front grip, by repulsion or contrast means, cooperating with the graft means, which places the locking mechanism steadily in the work position, engaging the graft means and preventing rotation of the polygonal bar.
  • the improved anti-burglary (or anti-intrusion) handle of the invention can be assembled more quickly and easily than the equivalent handles of the prior art with respect to which it is constructively less complex and articulated, to the full advantage of its production cost.
  • the improved anti-burglary handle of the invention has a more uniform and homogeneous aesthetic impact, without visible points of discontinuity (especially at the front grip), and therefore more pleasant and appreciated by the market than similar known anti-burglary handles, while providing a number of constructive components, also not in sight, lower than these ones.
  • the improved anti-burglary handle of the present invention comprises a front grip of standard type, used also for handles of traditional type and depict of the anti-burglary function, with the consequence of generating advantageous scale economies at the production stage.

  • the improved anti-burglary handle 1 comprises:
  • a front grip 2 at user's availability who accesses it from the inside of a room of a building, provided with a terminal neck 3 suitable to be be axially, stably and revolvingly coupled with the linear portion P of the perimetrical frame T of the panel A belonging to a window or a door;
  • a polygonal bar 4 visible starting from figure 2, defining a linear axis X, revolvingly coupled with the front grip 2 and suitable to be partly and frontally inserted into the linear portion P of the perimetrical frame T, from which it projects by a predefined initial stretch 5 towards the inside of said room of the building;
  • a locking mechanism in the assembly indicated with 6 and operatively connecting the polygonal bar 4 with the front grip 2 in such a way that the locking mechanism 6 on one side, as a result of the handling of the front grip 2 itself carried out by the user from the inside of the room, allows to transmit a torque to the polygonal bar 4 and, on the other side, prevents to transmit a torque from the polygonal bar 4 to the front grip 2, the locking mechanism 6 taking a work position (see figures 3 and 4), in which the rotation of the polygonal bar 4 and of the front grip 2 around the linear axis X is inhibited, and at least a release position (see figures 15 and 16), in which the rotation of the polygonal bar 4 around the linear axis X is allowed, caused by the user by rotating the front grip 2 from the inside of the room.
  • the locking mechanism 6 comprises graft means, generally numbered with 7, operable by actuation means in axial sliding along the linear axis X by:
  • the predefined initial stretch 5 of the polygonal bar 4 is inserted into an axial slot with a polygonal profile 9 made along the terminal neck 3 of the front grip 2 in such a way as to define an axial inner gap 10 useful for constructive purposes.
  • Figures 4 and 6 show that the polygonal bar 4 is made integral with the locking mechanism 6 and the terminal neck 3 of the front handle 2 through coupling means, as a whole numbered with 11 and comprising, for instance, squared surfaces which delimit an axial (or central) through hole made in at least one of the components of the locking mechanism 6 which are conjugated with the squared surfaces of the polygonal bar 4: this is therefore a coupling comparable, in an extensive sense, to that one which in technical industrial drawing is known as "key coupling".
  • the linear axis X defined by the polygonal bar 4 is substantially orthogonal to the plane defined by the linear portion P, facing the room of the building, of the perimetrical frame T of the panel A.
  • the actuation means comprise in this case the terminal neck 3 of the front grip 2, operated in axial sliding by the user's hand by means of a thrust action exerted on the outer surface 2a of the front grip 2 in such a manner as to cause the axial sliding of the graft means 7 and the passage of the locking mechanism 6 from the work position to the release position.
  • the repulsion means 8 previously introduced include any of the mechanical systems able to cause a spontaneous movement of the element which they cooperate with by contact, selected from the group consisting of elastic recovery means, magnetic means having the same polarity which generate a spontaneous bumper or repulsive action and/or the like: in this case, figures 6 and 8-10 show that the repulsion means 8 comprise in this case, on a purely preferred but not binding basis, elastic recovery means 12, such as a helical spring.
  • the repulsion means 8 are hidden from view and, as it can be seen in figures 5 and 6, are arranged near the free end 3b of the terminal neck 3 of the front grip 2, internally or externally to the terminal neck 3 itself.
  • the graft means 7 which, in the invention, determine the locking mechanism 6, comprise a gear, generally indicated with 13 and belonging to:
  • the graft means 7 at least partly belong to a fixed base block 16 - which, in the specific case, therefore constitutes the aforesaid fixed auxiliary body - suitable to be applied through fastening means, as a whole indicated with 14 and only partly visible in the attached figures being of the type per se known to the man skilled in the art, to the linear portion P of the perimetrical frame T at a structural through opening R made in the linear portion P itself and shaped in such a way as to define an inner central room 28 and a first axial through opening 29 coaxial to the terminal neck 3: the polygonal bar 4 orthogonally crosses the fixed base block 16 in such a way that a predetermined final stretch (for simplicity, not identified with a numerical reference in the accompanying figures and opposite to the predetermined initial stretch 5) of the second end 4b of the polygonal bar 4 soaks in the perimetrical frame T up to interfere with movement mechanisms of the panel A which notoriously cause opening/closing of the window, balcony or door.
  • a predetermined final stretch for
  • the graft means 7 are arranged at least partly inside a central portion 17 of the fixed base block 16 and are therefore hidden from view, protected from always harmful and contraindicated accidental bumps by external stranger bodies who could even irreparably compromise their structural integrity or from unseemly and unwanted external agents that could cause their slow but inexorable wear, with the obvious disadvantages that would result for their function.
  • the graft means 7 comprise, according to what is visible in the sections of the figures 6, 13 and 18 and with greater precision in the exploded views of figures 22 and 23:
  • a plurality of shaped teeth 18 protruding from the outer side surface 19a of a movable operating peg 19 - which, in the specific case, therefore constitutes the movable main body - having an axial through hole 20 into which the polygonal bar 4 is inserted, according to linear axis X, and which always protrudes from the operating peg 19 for a prefixed portion 15 comprising a second end 4b opposite to a first end 4a contained into the terminal neck 3 of the front grip 2;
  • the shaped teeth 18, in this case preferably present in a number of eight, are in particular: ⁇ in a number equal to the operating positions (of complete closing and partial opening, for example at tilt-and-turn shutter, and again of complete opening of the through room made in the wall of the building and which receives the panel A) allowed for the front grip 2 as a result of the rotation of the latter and of the polygonal bar 4 around the linear axis X impressed by the actuation means;
  • the graft means could include a number of shaped teeth - associated with the movable operating peg - and of corresponding counter-shaped seats associated with the fixed base block - different from that one already indicated, visible in the attached figures, this number being able to vary depending on the construction choices or customer needs, starting from one.
  • Figures 22 and 23 show that, preferably, the shaped teeth 18 are arranged at a first end 19b of the movable operating peg 19 and, when they are present in at least two elements, are uniformly distributed on the outer side surface 19a of the operating peg 19 itself.
  • the axial through hole 20 presents a squared or polygonal profile (in the specific case, square), equivalent to that one of the polygonal bar 4 which is therefore inserted or conjugated in the movable operating peg 19.
  • the movable operating peg 19 includes between each pair of shaped teeth 18 an abutment septum 22 provided with an inner strike wall 23 which acts as end-of-stroke of the axial movement of the graft means 7 - notably of the movable operating peg 19 and in the direction given by the arrow G of figure 21 - as against it a counter-shaped dent 24 contrasts, better visible in figure 25, arranged between each pair of counter-shaped seats 21 of the fixed base block 16 when the locking mechanism 6 takes the work position.
  • each of the shaped teeth 18 and the abutment septum 22 have substantially the same profile in cross section, as well as each of the counter-shaped seats 21 and the counter- shaped dent 24 have substantially the same profile in cross section.
  • each of the shaped teeth 18, the abutment plate 22, each of the counter-shaped seats 21 and the counter-shaped dent 24 have in cross section a tapered, frusto-conical or in the shape of an isosceles trapezium provided with an arched-profile larger base and smaller base, in which the arched smaller base of each of the shaped teeth 18 and of the abutment plate 22 is arranged against the outer side surface 19a of the movable operating peg 19, and in which the arched smaller base of each of the counter- shaped seats 21 and of the counter-shaped dent 24 is located close to the inner wall 16a of the base block 16.
  • the upper outer surface 22a of the abutment septum 22 is concave, in order to ease rotation of the movable operating peg 19 (whose main body 48 preferably has a cylindrical shape, as it can be clearly seen in figure 26) integral with the polygonal bar 4.
  • the aforesaid upper outer surface 22a is separated from the upper convex outer wall 18a of the shaped teeth 18 adjacent thereto through a sharp edge 25 which ensures, by interfering with a pair of opposite convex ribs 26, 27 projecting from the inner wall 16a of the fixed base block 16, the emission of a slight snap noise, but clearly perceptible by the user when the front grip 2 is rotated around the linear axis X to take one of its possible operative positions.
  • the opposite convex ribs 26, 27 are axially adjacent to the counter-shaped dent 24 in between each pair of counter-shaped seats 21, in an inner central room 28 defined in the fixed base block 16.
  • the improved anti-burglary handle 1 of the invention also comprises a laminar finishing plate 30, visible in figures 22-25 and on its own in figure 30, coupled externally with the fixed base block 16 in such a manner that, when the handle grip 2 is in applicative conditions (that is coupled with the perimetrical frame T of the panel A), it is placed near the outer surface E belonging to the linear portion P of such a perimetrical frame T and surrounds the previously introduced structural through opening R, housing at least part of the fixed base block 16.
  • the improved anti-burglary handle 1 of the present invention comprises, in this specific case, auxiliary locking and safety means, as a whole numbered with 31, operable by the user only from the inside of the room and normally at least partly in view, coupled with the locking mechanism 6 and with the terminal neck 3 of the front grip 2 between which they are interposed, in such a way as to alternately define:
  • auxiliary locking and safety means 31 allow the actuation means to make the graft means 7 sliding axially and to move the front grip 2 and the polygonal bar 4 in sliding and rotation.
  • auxiliary locking and safety means 31 comprise:
  • a positioning ring 32 visible on its own in figures 27-29, arranged coaxial to the terminal neck 3 of the front gripe 2 and to the polygonal bar 4 which crosses it, which can be freely handled in rotation by the user around the linear axis X for defining the operative position of the auxiliary locking and safety means 31, in which the positioning nut 32 is disposed close to the side edge 3a of the terminal neck 3 and axially spaced apart from the outer front part of the locking mechanism 6 (notably from the front face 16b of the fixed block base 16), and the non-operative position of the auxiliary locking and safety means 31, in which the positioning nut 32 is disposed close to the outer front part of the locking mechanism 6 and axially spaced apart from the side edge 3a of the terminal neck 3: it should be noted in particular that the positioning ring 32 is provided on the inner wall 32a with a pair of protruding teeth 33, 34 symmetrically arranged with respect to the linear axis X;
  • tubular body 35 arranged internally coaxial to the positioning ring 32, integral with the front face 16b of the fixed base block 16 and provided with a free side edge 35a on which the protruding teeth 33, 34 rest and in which two inclined surfaces 36, 37 are identified which are crossed by the protruding teeth 33, 34 during the rotation of the positioning ring 32 around the linear axis X determining its axial progress or retraction which places the auxiliary locking and safety means 31 in the non- operative position starting from the operative position and vice versa, respectively.
  • the axial progress or retraction of the positioning ring 32 causes in this case the corresponding positioning of the locking and safety means 31 in the non-operative position and in the operative position. More in detail, the positioning ring 32 describes an angle of 90° passing from the operative position to the non-operative position and vice versa of the auxiliary locking and safety means 31, with rotations occurring in verses opposite each other, as figure 11 specifically demonstrates.
  • the positioning ring 32 is provided laterally with a tubular element 38 which:
  • ⁇ is coaxial to the positioning ring 32 with respect to which presents a smaller diameter
  • the axial groove 39 conveniently presents larger dimensions with respect to the axial slot with a polygonal profile 9 which houses the predefined initial stretch 5 of the polygonal bar 4: this in order to allow a correct housing of the repulsion means 8.
  • the rotation of the positioning ring 32 around the linear axis X when the auxiliary locking and safety means 31 pass from the aforesaid operating position to the aforesaid non-operative position and vice versa is stopped by end-of- stroke means, indicated as a whole with 41 and better visible in figure 24, associated with the free side edge 35a of the tubular body 35.
  • the end-of-stroke means 41 comprise, in the example described herein, two pairs of orthogonal flat walls 42, 43, defining a plane parallel to the linear axis X and arranged on the free side edge 35a of the tubular body 35, the protruding teeth 33, 34 of the positioning ring 32 striking against a pair of these orthogonal flat walls 42, 43 when the auxiliary locking and safety means 31 take the operative position or non-operative position.
  • Figure 24 also shows that, on the free side edge 35a of the tubular body 35, each of the orthogonal flat walls 42, 43 defines, advantageously though not necessarily, together with a transversal flat wall 44 defining a plane perpendicular to the linear axis X, a lateral housing 45 adjacent to each of the inclined surfaces 36, 37: in such a lateral housing 45 one of the protruding teeth 33, 34 is then removably positioned when the auxiliary locking and safety means 31 take the operative position or non-operative position.
  • each of the protruding teeth 33, 34 is at least partly firmly kept in the lateral housing 45 by means of a raised edge 46 which separates the lateral housing 45 from each of the inclined surfaces 36, 37 and is suitable to prevent an accidental separation of each of the protruding teeth 33, 34 from the lateral housing 45 itself and their consequent fortuitous and unwanted sliding on the inclined surfaces 36, 37, with the evident advantages that follow in terms of operation of the improved handle 1 and of its handling by the user.
  • the tubular body 35 is made in a single body with the fixed base block 16, just as the tubular element 38 is made in a single body with the positioning ring 32.

  • auxiliary locking and safety means 31 are placed in this position (shown in figures 11, 12, 13 and 14), a part of the graft means 7 is free to slide along the linear axis X, which occurs as soon as the user exerts a pushing action on the front grip 2 (according to the direction of the arrow F of figure 17) which places the side edge 3a of the terminal neck 3 of the improved handle 1 close to the first side edge 3b: see in this respect figures 15, 16, 17 and 18.
  • the user can therefore rotate at will the front grip 2, and with it the polygonal bar 4, around the linear axis X, causing the simultaneous rotation of the movable operating peg 19 of the graft means 7: in this rotation, the upper outer wall 18a of the shaped teeth 18 and above all the sharp edge 25 intercept the opposite convex ribs 26, 27 causing a noise clearly perceptible by the user who can thus appreciate the effective rotation of the system under the corresponding action he exerts with his hand on the front grip 2.

  • the inner core 361 also presents at least a first portion of the axial through hole 366 having a size smaller than a second portion of such an axial through hole 366 of the movable intermediate sleeve 359.

  • Figures 53 and 56 in particular show that the inner central room 369 of the fixed base block 365 houses a service disc 371 which presents an axial through hole 372 into which the polygonal bar 353 is inserted and an annular outer surface 371a provided with a series of concave sections 373, in general as many as the shaped teeth 362 of the intermediate sleeve 359 and the counter-shaped seats 363 of the central portion 367 are.

  • the locking mechanism 355 notably, the graft means 356, in the invention
