Definitions

  • the present invention relates to a handle for a sliding door that is widely used in the field of windows and doors.
  • a method for mounting a handle for a sliding door is also an object of the present invention.
  • sliding door means a door whose leaf is movable slidingly along an opening and closing direction.
  • handles are known which are provided with a rotatable knob comprising an outer portion that can be gripped by a user and an inner portion extending along an axis of rotation of the knob.
  • the known handles are also provided with a pawl, also comprising an outer portion and an inner portion extending along a central axis of the pawl itself.
  • the inner portion of the pawl and the inner portion of the knob are telescopically couplable, so that the outer portions of the knob and of the pawl can be arranged and abut on opposite sides of the sliding door.
  • the inner portion (so-called “male”) of the knob is configured to fit into the inner portion (so-called “female") of the pawl and to slide into it in order to cause an appropriate distancing or reciprocal approach of the knob with the pawl, in order to adapt the handle to the thickness of the door on which it is mounted.
  • the known handles comprise a pair of washers each installable near a respective end of a through hole made in the sliding door. Each washer is inserted into a housing made on the surface of the door and is provided with a central opening through which the washer is fitted on the knob or pawl.
  • the known handles comprise a seeger ring (or other elastic metal ring) and a washer both fitted on a receiving portion of the pawl and of the knob.
  • the washer 300 wraps the pawl 301 or the knob 302 and is interposed between a seeger ring 303, positioned within a circumferential groove suitably obtained on the receiving portion of the knob or the pawl, and a washer 304 in mechanical abutment with the outer portion of the knob or of the pawl.
  • the knob or the pawl is axially constrained thanks to the shoulders and undercuts provided by the seeger ring and by the washer in the receiving portion.
  • the known handles can be supplied with knob and pawl already mounted on the washer or even in a disassembled condition; in this case, an operator must take care of properly installing the washer and the seeger ring-with respect to the washer to accommodate the knob or the pawl that will be, at the end of the installation, flush with a respective surface of the door.
  • the knob and the pawl have been axially constrained, it is possible, by means of the telescopic coupling between the respective portions of the knob and of the pawl, to adapt the handle to the thickness of the sliding door on which it is mounted.
  • the knob and the pawl are mutually distanced by extracting the inner portion of the knob from that of the pawl.
  • the knob and the pawl are mutually approached by further inserting the inner portion of the knob inside that of the pawl.
  • the maximum thickness of the leaf on which the handle can be mounted is therefore defined by the maximum pull-out of the inner portion of the knob with respect to the inner portion of the pawl, i.e. by the maximum possible length of the telescopic coupling.
  • the minimum thickness of the leaf on which the handle can be mounted is instead defined by the total insertion of the inner portion of the knob inside that of the pawl.
  • a shim must be inserted between the washer and a respective side surface of the door.
  • the shim is configured to compensate for the impossibility of further inserting the inner portion of the knob inside that of the pawl.
  • the washer can be lowered, i.e. its encumbrance along an axis of rotation of the handle is reduced, so that the washer can be fully inserted into the housing made on the surface of the door.
  • the washers are flush with the respective side surfaces of the door, but the knob and the pawl are protruding with respect to the washers themselves, as they cannot be reduced in terms of overall dimensions.
  • the known handles are thus made aesthetically unpleasant and are such that they offer a poor manual grip by a user since, having lowered the washer, the portion within which a user can insert the fingers to move the door is reduced.
  • the technical task of the present invention is to provide a handle for a sliding door and a relative mounting method that are able to overcome the drawbacks arising from the prior art.
  • the object of the present invention is therefore to provide a handle that is adaptable to be mounted flush with surfaces of sliding doors of different thickness, in particular also of doors having a thickness of less than 38 mm.
  • a further object of the present invention is to provide a handle that is simpler to mount and less expensive.
  • a further object of the present invention is to provide a method for mounting a handle in a simple and fast manner.
  • the invention relates to a handle for sliding door comprising a rotatable knob having an outer portion with a greater diameter defining frontally a manual gripping region for a user, and an inner portion with a lesser diameter extending along an axis of rotation of the knob.
  • the handle further comprises a pawl comprising an outer portion with a greater diameter and an inner portion with a lesser diameter extending along a central axis of the pawl.
  • the inner portion of the pawl and the inner portion of the knob are telescopically couplable, so that the outer portions of the knob and of the pawl can be arranged on opposite sides of a sliding door.
  • the handle also comprises, for the knob and the pawl, a washer that is applicable stably to a hole made in the sliding door.
  • the washer is provided with a hole, typically central, by which the washer itself is fitted to the knob or pawl.
  • a connecting ring is interposed between at least one of the washers and the respective knob or pawl that is fitted stably to a receiving portion of the knob or of the pawl and provided with an annular recess within which an edge is housed stably, defining the hole of the washer.
  • the connecting ring comprises, on an outer surface, a first and a second protrusion cooperating to bound the annular recess and to retain the edge by an undercut.
  • the connecting ring comprises an inner relief that is stably engageable within a respective recess of the corresponding receiving portion, preferably with a snap engagement.
  • the connecting ring stably constrains the knob or pawl to the respective washer, so that the knob or pawl is locked thereon.
  • the introduction of the connecting ring makes it possible to reduce the overall dimensions of the handle, in such a way as to make it installable even on doors with thicknesses less than 38 mm, without it protruding and being uncomfortable to the eye and not very functional.
  • the insertion of the connecting ring allows to decrease the axial overall dimensions of the receiving portion of the knob and of the pawl (indicated in figure 1A by means of an arrow) since the seeger ring and the washer are replaced by a single body.
  • 100 denotes a handle for a sliding door “P” comprising a rotatable knob 10 provided with an outer portion 11 with a larger diameter, defining frontally a manual gripping region “R” for a user, and an inner portion 12 with a lesser diameter extending along an axis of rotation "X1" of the knob 10.
  • the manual gripping region “R” comprises a rib that divides the manual gripping region “R” itself into two gripping zones “Z” to allow movement of the door "P".
  • the rib of the manual gripping region “R” also allows the rotation of the knob to control the extraction and retraction of a latch (not illustrated).
  • the handle 100 further comprises a pawl 20 comprising an outer portion 21 with a greater diameter and an inner portion 22 with a lesser diameter extending along a central axis "X2" of the pawl 20.
  • the inner portion 22 of the pawl 20 and the inner portion 12 of the knob 10 are telescopically couplable so that the outer portions 11, 21 of the knob 10 and of the pawl 20 can be arranged on opposite sides of the sliding door "P", like for example shown in figures 2A and 2B .
  • the inner portion 12 of the knob 10 is slidably movable within the inner portion 22 of the pawl 20 so as to assume, preferably continuously, a plurality of stable positions.
  • the knob 10 and the pawl 20 are mutually moved away by extraction or pulling out the inner portion 12 of the knob 10 from the inner portion 22 of the pawl 20.
  • the inner portion 12 of the knob 10 is wedged and locked within the inner portion 22 of the pawl 20.
  • the inner portion 12 of the knob 10 is provided with a plain screw, or other connecting element, having a terminal end 12a substantially conformed as a truncated cone and configured to cooperate with the inner portion 12 of the knob to spread it apart so as to interfere with the inner portion 22 of the pawl 20 and thus block the mutual approach or distancing of the pawl 20 and of the knob 10, i.e. so as to lock the knob 10 and the pawl 20 in a predetermined mutual position.
  • the plain screw or other connecting element is moved relative to the inner portion 12 of the knob 10 along the direction of the axis X1, such that the terminal end 12a with truncated cone interferes with the side surfaces of the inner portion 12, pushing them in abutment against the side surface of the inner portion 22 of the pawl with which they are telescopically coupled, as previously described.
  • the handle 100 further comprises, for the knob 10 and for the pawl 20, a washer 30 that is applicable stably to a hole made in the sliding door and provided with an opening, preferably central, by which the washer 30 is fitted to the knob 10 or pawl 20.
  • each washer 30 is made of metal material, for example zamak, of steel machined by deep drawing and of turned brass.
  • the washer 30 has a hollow main body 30b with preferably a circular section within which the outer portion 11 of the knob 10 and the outer portion 21 of the pawl 20 can be housed.
  • the washer 30 comprises a circumferential edge 30c configured to protrude externally from the hole made on the door "P" so as to abut with contact with the side surface of the door "P" itself.
  • a connecting ring 40 is interposed between at least one of the washers 30 and the respective knob 10 or pawl 20 .
  • the handle 100 comprises a connecting ring 40 interposed between the knob 10 and the respective washer 30 and a further connecting ring 40 interposed between the pawl 20 and the respective washer 30.
  • the connecting ring 40 is stably fitted on a receiving portion 14, 24 of the knob 10 or of the pawl 20, respectively and is provided with an annular recess 41 within which a typically circular edge 30a defining the typically central hole of the washer 30 is housed stably.
  • the receiving portion 14, 24 is comprised between the outer portion 11, 21, and the inner portion 12, 22 of the knob 10 and/or pawl 20, respectively.
  • the receiving portion 14, 24 has an intermediate diameter between the diameter of the outer portion 11, 21 and the diameter of the inner portion 12, 22.
  • the connecting ring 40 extends around an axis "A", preferably with axial symmetry.
  • the connecting ring 40 has a dimension, measured along the aforesaid axis "A", comprised between 1.5 mm and 4 mm.
  • the connecting ring 40 comprises, on an outer surface, a first and a second protrusion 42a, 42b cooperating to bound the aforesaid annular recess 41 configured to retain the edge 30a of the hole of the washer 30 by an undercut.
  • the first protrusion 42a extends in proximity of a base surface 40a of the connecting ring 40, while the second protrusion 42b extends in proximity of a head surface 40b of the connecting ring 40 ( figure 4A ).
  • the first protrusion 42a is provided with a lead-in surface 42a' conformed that the connecting ring 40 is snap-fitted within the hole, for example central, of the washer 30.
  • the lead-in surface 42a' of the first protrusion 42a is curved such that it facilitates the snap-fitting of the connecting ring 40 within the hole of the washer 30.
  • the lead-in surface 42a' extends from the base surface 40a of the connecting ring 40 and extends laterally away therefrom towards the recess 41 so as to define an arc or a substantially concave curvature.
  • the connecting ring 40 When the connecting ring 40 is inserted into the hole of the washer 30, the connecting ring 40 is brought closer to the hole so that the axis "A" of the connecting ring 40 is aligned with the axis of the hole of the washer 30.
  • the connecting ring 40 is oriented so that the base surface 40a faces the hole itself.
  • the first protrusion 42a is arranged in proximity of the edge 30a of the hole of the washer 30.
  • an axial thrust is imprinted on the connecting ring 40 such as to cause a mechanical abutment between the circular edge 30a of the hole of the washer 30 and the lead-in surface 42a' of the first protrusion 42a of the connecting ring 40.
  • the connecting ring 40 is pushed towards the hole of the washer 30, the lead-in surface 42a' of the first protrusion 42a slides in contact with the edge 30a of the hole of the washer 30 progressively deforming.
  • the pressure exerted by the edge 30a of the hole of the washer 30 on the lead-in surface 42a' of the first protrusion 42a during the insertion of the connecting ring 40 forces the first protrusion 42a to progressively bend towards the recess 41.
  • the first protrusion 42a undergoes an elastic return and the recess 41 accommodates the edge 30a of the hole.
  • the edge 30a of the hole of the washer 30 is trapped between the first and second protrusion 42a, 42b, inside the recess 41 by an undercut.
  • the connecting ring 40 itself also undergoes a radial deformation such as to momentarily reduce its diameter in order to facilitate the snap-fitting thereof.
  • the connecting ring 40 is elastically deformable at least in the radial direction.
  • the connecting ring 40 is elastically deformable and is made, for example, of metal, metal alloy, plastics, etc.
  • the radial elasticity is favoured by a radial notch 44 made on the connecting ring 40 in such a way that it extends along an open line.
  • the connecting ring 40 is deformable between a deformed configuration, in which it is elastically deformed so as to vary its diameter, and a rest configuration, in which it is not subject to any deformation.
  • the connecting ring 40 in the deformed configuration, can be compressed elastically so as to reduce its diameter by a mutual approach of the ends of the connecting ring 40 that bound the radial notch 44 itself.
  • the connecting ring 40 In use, therefore, during the approach of the base surface 40a of the connecting ring 40 to the hole of the washer 30, the connecting ring 40 has a diameter substantially equal to that of the hole of the washer 30.
  • the connecting ring 40 in order to snap-fit the connecting ring 40 into the hole of the washer 30, i.e. so that the lead-in surface 42a' of the first protrusion 42a comes into contact with the edge 30a of the hole of the washer 30 and is progressively deformed, the connecting ring 40 is brought into a deformed configuration, so as to be compressed radially by exploiting the radial notch 44.
  • the connecting ring 40 is deformed radially until the ends that bound the radial notch 44 are substantially in mutual contact (or even overlapping) eliminating the radial notch 44 itself. Subsequently, the connecting ring 40 is snap-fitted into the hole of the washer 30 by deforming the first protrusion 42a. In this situation, the connecting ring 40 undergoes an elastic return in the radial direction such as to move, at least partially, the ends that bound the radial notch 44 away and such as to imprint on the edge 30a of the hole a radial thrust capable of stably constraining the connecting ring 40, and in particular the recess 41, to the edge 30a of the hole.
  • the connecting ring 40 is firmly wedged within the hole of the washer 30, so that the recess 41 accommodates the circular edge 30a of the hole and retains it by an undercut given by the first and second protrusions 42a, 42b.
