Definitions

  • the present invention relates to a sliding-door handle with latch, in which the door is provided with an upright having a plate provided with a hole for engagement of the latch.
  • the invention relates to sliding doors which are totally concealed inside a receiving compartment formed in a wall, without however losing its universality as a result. It can in fact be advantageously used also in sliding doors which are partially concealed, or also in some types of hinged doors.
  • any sliding door whether it is of the totally concealed type or not, always has the problem that it is not easily accessible, for gripping of the handle, in the end position where the door is fully open.
  • the sliding door is not of the totally concealed type, it is mounted so as to project from the wall, in the end open position, by the amount which is needed in order to be able to easily grip the handles thereof.
  • This accessory normally consists of an insert located in the front side of the door and provided with a curved hole, into which one can introduce a finger so as to displace the door from its entirely open end position into a more or less extracted position, where it is then possible to operate the inset handle.
  • a further problem as yet unresolved is represented by the need to provide the aforementioned handles, which are particularly flat and have necessarily small dimensions, with a latch which also allows stable and reliable closing of the door, whenever necessary.
  • the object of the present invention is that of eliminating all the drawbacks indicated above. This is achieved by means of a handle, comprising a special movable latch, which can be hidden inside the door and is provided with an end hook and an operating body with which the hook, from an end rest condition in which it is totally hidden inside the door, is projected towards the outside of the latter until it engages in an operative condition with a plate mounted on the fixed upright of the door, hooking up with it, and vice versa.
  • the handle in question allows the door to be concealed totally inside the containment box, while allowing the user to pull out the door from the wall box by operating a single member consisting precisely of the handle and by means of a single operation.
  • the solution obtained, consisting in a single member, is particularly economical both in terms of production costs and in terms of assembly costs.
  • the possibility of providing a perfectly symmetrical handle means that it is possible to use the latter indifferently as a right-hand handle or as a left-hand handle, acting in exactly the same manner on both sides of the door.
  • the latch 15 is mounted on the leaf side 50 of the door 4 intended to be associated, during closing of the door 4, with a facing upright 12 of the counter-frame provided with a plate 13 having a hole 14 for engagement of the latch 15.
  • the latch 15 essentially comprises: a plate element 16, contained in the door 4 and formed so as to have an end hook and a slot 19 opposite the hook 17; a fixed pin 20 onto which the slot 19 of the plate element 16 engages; and a body 23 for operating the latch 15, mounted rotatably about a fixed axis 24 and having an eccentric pin 25 on which the plate element 16 is hinged.
  • the hook 17 comprises a head 30 with a front face 31 and a rear face 32 which are flat, shaped and mutually converging at an acute angle towards a vertex 51 located towards the bottom end of the door 4.
  • the shape of the plate element 16 and the locations of the rotating pin 25 and the fixed pin 20 are such that, following rotation of the operating body 23, an oscillating movement is imparted to the plate element 16 in the plane 40 in which the door 4 lies, as a result of which the hook 17, from an end rest condition in which it is hidden inside the door 4, is projected towards the outside the latter, until it engages, in an operative condition, with the plate 13, hooking up with it after passing through the hole 14 thereof, and vice versa.
  • the front and rear faces 31 and 32 of the head 30 are oriented, in particular, so as to be equidistant with respect to the plate 13 of the upright 12 in the end positions reached by the plate element 16 during the oscillation movement.
  • the latch 15 comprises moreover recall means interacting with the plate element 16 so as to recall always the latter into a stable immobile condition corresponding, alternately, to the rest condition or to the operative condition.
  • the recall means are actuated by a resilient reaction element 26, consisting of an extension spring, with opposite ends 27, 28 respectively anchored on one side to the plate element 16 and on the other side to a fixed point 29 of the door 4.
  • the extension spring acts in a direction which is displaced with respect to the axis 24 of rotation of the operating body 23.
  • the presence of the spring therefore causes a rotational moment of the plate element 16 about the fixed pin 25 which, in the absence of external forces applied to the operating body 23, always brings the plate element 16 itself into one of its end positions: i.e. the rest position or operative position, depending on the position assumed by the spring with respect to an ideal line Y, which joins the fixed pin 25 to the fixed point 29.
  • the latch 15 is equipped with means for stable locking of the plate element 16 in order to block rotation of the plate element 16 in the aforementioned end positions, in the same way as a conventional key-type locking system.
  • the locking means (Fig. 9) are actuated by a pawl 35 supported by a pommel 37 rotoidally mounted on the door 4 and by a cam 36 formed on the plate element 16.
  • the pawl 35 and the cam 36 are shaped in a complementary manner and are mounted on the latch 15 so as to be movable with respect to one another between two end positions.
  • the latch 15 may be advantageously mounted inside the sliding door 4, even in a zone 38 of fairly limited thickness, such as for example that in which the inset handles 1 of the door 4 are formed.
  • the latch 15 can also be incorporated in the handle 1 itself. This allows the realization of the closing assemblies which are highly efficient from a functional point of view, having a great degree of constructional simplicity and posssessing a pleasing aesthetic appearance. If we observe Figures 1 and 2, it can be noted in fact that, by forming the handles 1 as recessed impressions 2 in the door 4, which can be accessed by the user both tangentially and transversely with respect to the plane 40 in which the door 4 lies, the body 23 operating the plate element 16 of the latch 15 may be mounted, inside the recessed impression 2, projecting transversely with respect to the plane 40 in which the door 4 lies.
  • the access space in a first entry direction, is accessible such that the user is able to introduce a finger tangentially with respect to the plane 40 in which the door 4 lies and curl it around the operating body 23: as a result, it is possible both to operate the latch 1 and extract the door 4 from the containment compartment in the wall.
  • Figure 12 it can be noted, moreover, that the latch 15 is associated with a handle 1 which can be fixed to the door 4 by means of simple screws 60 which are inaccessible when the door 4 is closed.
  • the screws 60 may moreover be advantageously hidden from sight, even when the door 4 is open, by means of a cover 61 fitted onto a complementary cavity 62 formed on the handle 1 and designed to receive the heads 63 of the screws 60.
  • the invention thus conceived may be subject to numerous modifications and variants, all of which fall within the scope of the innovative idea. Moreover, all the details may be replaced by technically equivalent elements.
