Definitions

  • the present invention relates to a cremone bolt handle with lock usable, in particular, for casings with side hung and top hung opening, i.e. casings rotationally openable both on vertical and horizontal axes and it is indicated to allow utilisation under safe conditions.
  • the present handle is usable to prevent undesired or dangerous openings of the casing, whilst still allowing for the possibility of aerating the rooms closed by the casing fitted with the subject handle; possible applications of the handle can be had in the field of public and social construction, such as hospitals, schools, crèches and the like, or in home uses in the presence of children or disabled persons.
  • a handle called a cremone bolt handle, i.e. a handle revolving around an axis perpendicular to the plane of the sash and associated to appropriate closure organs comprising rods or bars interacting, upon command, between the movable frame and fixed frame of the casing;
  • a handle comprising essentially the control grip, which acts on the underlying linkage sliding inside the section bars constituting the casing, and which is supported by a body or case able to be associated at the front to the upright of the movable frame.
  • Such handles can assume three positions, angularly differentiated by 90°, corresponding to the three possible functional configurations of the casing: vertical position with downward disposition for closure, horizontal position for side hung opening and vertical position with upward disposition for top hung opening.
  • cremone bolt handles with lock or with detachable grip are used.
  • the first solution attempt solves only the requirement to close the casing since the lock allows only to block the movable frame onto the fixed frame in the closed position; in practice, exit through the window is prevented but aeration of the related rooms is also thereby prevented at the same time.
  • the second solution attempt allows, once the casing is on the top hung opening conformation, to detach the grip from the handle body.
  • This feature thus entails for assigned personnel to carry the grip of the handle with them, with the deriving bulk; moreover, once the casing has been set to the open wing (top hung) position, it cannot be closed without the intervention of the aforesaid assigned personnel.
  • Another negative aspect of such a solution derives by the poor aesthetic effect generally brought about by the handle once it is deprived of its grip.
  • the object of the present invention therefore is to eliminate the aforementioned drawbacks with a cremone bolt handle with lock wherein the activation of the lock (i.e. closure with a key) allows to position the handle on two configurations corresponding, respectively, to closed casing and to top hung open casing.
  • the handle 1 constituting the object of the invention is of the type usable on a movable frame to allow a side hung and top hung opening.
  • the figures do not show fixed frame and movable frame and of the subject handle Figure 2 shows a slider 5 which defines the connection with the related motion imparting organs provided and acting between movable frame and fixed frame.
  • the cremone bolt handle 1 comprises a grip 3 and a case 4.
  • the grip 3 is associated, stably and with the freedom to rotate, to the case 4 in correspondence with a seat 40 defined by a hole provided on the case itself.
  • Rotating the grip 3, the rotational motion imparted is transformed by a gear wheel - rack coupling to the slider 5 which, translating according to the directions indicated as F 1 and F 2 in Figure 2, leads the motion-imparting organs in such a way as to position the movable frame on at least three configurations C, A and R, corresponding to closure, side-hung opening and to-hung opening.
  • the motion-imparting organs provided on the movable frame are set in such a way as to make the closed casing configuration correspond to a vertical disposition (downward in the examples), the top hung opening configuration following immediately (i.e. obtainable with a 90° rotation from the vertical, horizontal disposition of the grip) and the side hung opening configuration in correspondence with a 180° rotation with respect to the closed position (upward vertical disposition in the examples).
  • the grip 3 presents its own portion 30 for connection to the case 4 (and to the motion-imparting organs of the movable frame) hollow, so as to define an essentially cylindrical cavity wherein can be inserted a cylinder 2 constituting the lock 2 of the handle 1.
  • the cavity presented by the grip 3 presents two sections with different diameter, with the one having the smaller diameter positioned closer to the connection with the case 4.
  • the cylinder 2 of the lock presents corresponding sections so as to be stably insertable inside the cavity of the connecting portion 3.
  • corresponding grooves 24 and 35 can be provided respectively on the cylinder 2 and within the cavity presented by the connecting portion 30.
  • a cylindrical pin 23 that prevents the relative rotation between cylinder 2 and grip 3.
  • the cylinder 2 presents a fixed part 26 and a movable part 27, positioned on top in the example shown.
  • a housing seat 28 for a key 8 In the movable part 27 is provided a housing seat 28 for a key 8, whereas at the bottom the exit is provided for, from the fixed part 26, of a movable end 22 which, in correspondence with activation of the lock, positions itself in such a way as to protrude from the lower part of the grip 3 for a value that in the example shown corresponds to the stroke L2 that the movable part 27 travels along in correspondence with the activation of the lock.
  • the fixed part 26 of the cylinder 2 presents at the bottom a smaller section portion 21 arranged coaxially with respect to the axis X of rotation of the handle.
  • This smaller section portion 21 presents a threaded seat 24 suitable for screwing a related screw 7 that secures the smaller section portion 21 to a gear wheel 57, shown in Figure 2, which defines the connection between the grip 3 and the slider 5 mentioned above.
  • the stem of the cylinder 2 of the lock comprises the pin of the grip 3, i.e. the connection between grip and motion-imparting organs is defined by the lock cylinder itself: in this way the diameter of the connecting portion 30 of the grip can have a particularly compact diameter, thereby contributing to improve the ergonomic and aesthetic characteristics of the subject handle.
  • a hole is provided which defines a seat 40 for association to the grip 3.
  • the seat 40 extends peripherally for at least an arc of circle 41 according to an angle ⁇ essentially corresponding to the angular value of the positioning difference between two configurations whereon the handle 1 can be positioned.
  • the movable end 22, when the lock is activated, is inserted into the extension 41 shaped as an arc of circle presented by the seat 40 and consequently limits the rotation of the grip 30 to the angle ⁇ .
  • the angle ⁇ in the non-limiting example shown in the drawings, has a value of 90°.
  • the angular difference between the positioning on the closure configuration C and the top-hung opening R is of 90° and, once the lock is activated, the grip can be rotated by 90° to allow the closure and only the top-hung opening of the casing.
  • the seat 40 can extend peripherally for two arcs of circle 41 and 41', diametrically opposed, in order to allow utilisation both on right-opening and on left-opening sashes.
  • a lock 2 of the cylinder type with five pistons can be used, in order to allow, with a limited size, a high number of combinations thanks to masterisation.
