Definitions

  • the present invention relates to a handle for door or window frames, in particular a handle for "interior" door or window frames.
  • Handles for door or window frames in particular for door or window frames made of metal, wood and synthetic material and the like, for interiors, such as doors separating rooms, are structurally simplified, in terms of their components, compared with handles "for exteriors" (such as known Cremone bolt handles), since the drive components are almost always already housed in the door or window frame, from which there exits, from one or both surfaces of the door or window frame, simply an operating shaft which normally has a square cross-section.
  • these handles basically comprise:
  • the handgrip is secured to the shaft, to prevent the handgrip from slipping off along the axis of the shaft, by connecting means consisting of a grub screw which is screwed into a radial through-seat in the handgrip and makes contact with a surface of the shaft.
  • the handgrip positioning unit is housed in the body and may consist, in one of the prior art solutions, of a circular, ring-shaped element, with a pair of opposite radial projections extending towards the inside of the ring. During engagement with the handgrip, these projections engage two diametrically opposed longitudinal through-openings or grooves made on the end of the handgrip with the square cross-section: in this way the ring is rendered integral with the handgrip.
  • the spring means are, in turn, inserted and connected respectively between the inner surface of the body and the positioning unit: in this way, rotation of the handgrip (corresponding to opening the door or window frame) and of the ring compresses the spring means which, once the handgrip is released by the user, allows the handgrip to move upwards again by acting on the ring.
  • another element which may be present in the handle may be a cover applicable on the body and held on it by contact with the handgrip when it is subsequently fitted to achieve a handle body colour and finish similar to the handgrip.
  • the aim of the present invention is therefore to overcome the above-mentioned disadvantages by providing a handle unit which allows a high degree of safety to be maintained for the handle unit, and in particular for the handgrip, irrespective of the presence of fixing means for it, without affecting the basic structure of the handle unit and possibility of substituting or removing the handgrip when necessary.
  • the present invention achieves said aim with a handle for door or window frames comprising at least a rotatable operating shaft, with a square cross-section, exiting a surface of the door or window frame;
  • the handle comprising: a body for connection to the surface of the door or window frame and having a through-opening engaged by the shaft; a handgrip which can be coupled in a matching fashion to the operating shaft, so that when the handgrip is rotated about an axis coinciding with the square shaft the configuration of the door or window frame is changed from closed to open; elastic means positioned in the body and designed to allow handgrip positioning in a predetermined position corresponding to the door or window frame closed configuration; means for stably joining the handgrip to the square shaft; means for releasable axial retention of the handgrip on the square shaft, located at the elastic means and acting on the end portion of the handgrip, where the handgrip is coupled to the square shaft, so as to stably hold the handgrip on the shaft irrespective of the
  • the handle labelled 4 as a whole, is fitted, in particular, on door or window frames made of metal, wood and synthetic material and the like, for interiors, such as doors separating rooms.
  • door or window frames labelled 1 in Figure 6, of the known type and only illustrated with a dashed line, comprise drive components designed to close and respectively open the door or window frame 1.
  • These components have at least a rotatable operating shaft 2, with a square cross-section, exiting a surface 3 of the door or window frame 1.
  • the shaft with square cross-section is also illustrated with a dashed line, since it is of the known type and is not strictly part of the present invention.
  • the handle 4 comprises:
  • the handle 4 comprises means 10 for releasable axial retention of the handgrip 7 on the square shaft 2, positioned at the elastic means 8 and acting on the end portion 7a of the handgrip 7, where the handgrip 7 is coupled to the square shaft 2, so as to keep the handgrip 7 stable on the shaft 2 irrespective of the presence of the stable joining means 9.
  • the above-mentioned stable joining means 9 normally consist of a threaded grub screw 9a which can be coupled radially in a seat 7s in the handgrip 7 (see Figure 6) then secures the latter through contact with the square shaft 2.
  • the handle 4 may also have a cover 30 for the body 5 which can be stably coupled on the body 5, and having a corresponding through-opening 30a for the handgrip 7; the handgrip 7 secures the cover 30 to the body 5 once fitted.
  • the above-mentioned elastic means 8 may comprise a contact element 8a positioned in the body 5 and connected to the end portion 7a of the handgrip 7 allowing handgrip 7 positioning in a predetermined position corresponding to the door or window frame 1 closed configuration.
  • the above-mentioned contact element consists of a ring 8a with two opposite radial projections 8c and 8d extending inside the ring 8a. These projections 8c and 8d can engage two diametrically opposed longitudinal through-opening or grooves 7c, 7d made on the end 7a of the handgrip 7 with the square cross-section.
  • the retaining means 10 are elastically deformable and can be coupled, on opposite sides, to the cylindrical end portion 7a of the handgrip 7, and in a relative circumferential groove 11 on the end portion 7a.
  • the retaining means 10 are inserted between the contact element 8a and the surface 3 of the door or window frame 1 and are applied on a surface 8b of the contact element 8.
  • the retaining means 10 are inserted between the contact element 8a and the surface 3 of the door or window frame 1 and can be connected directly to the body 5.
  • Figures 1, 2, 5 and 6 show how the retaining means may consist of a "U"-shaped elastic element 10 which can be connected to the surface 8b of the ring 8a opposite the surface 3 of the door or window frame 1.
  • the two legs 10a and 10b of the "U” can be coupled, snapping into position and on opposite sides, in the groove 11 in the cylindrical end portion 7a of the handgrip 7, allowing releasable axial retention (see Figure 6).
  • the elastic element 10 has the legs 10a and 10b of the "U" extending in such a way that they converge with one another to elastically snap onto and clamp the end portion 7a at the groove 11.
  • Figure 6 clearly shows how the "U"-shaped elastic element 10 is stably connected on the ring 8a, which has:
  • the retaining means may consist of an inverted "U"-shaped elastic element 10' where the connecting section 10'a of the "U” and the open ends of the legs 10'b, 10'c of the "U” are angled in such a way as to form a bridge-shaped elastic element 10'.
  • Said elastic element configuration allows it to jut out from behind the contact ring 8a and connect directly to the body 5.
  • the section 10'a and the ends of the legs 10'b, 10'c can be stably connected, by snapping into place, in corresponding seats or channels 15, 16 in the body 5, so as to allow elastic coupling, on opposite sides, of the two parallel legs 10'b, 10'c of the "U" in the groove 11 in the cylindrical end portion 7a of the handgrip 7, allowing its axial retention once fitted.
  • the angled ends of the legs 10'b, 10'c have an additional relative extension 17, 18, perpendicular to the ends, and opposite each other to form a lower connecting zone in the seat 16 in the body 5.
  • the elastic means 8 also comprise a spring for retuning the handgrip 7 to the door or window frame 1 closed position acting between the body 5 and the contact ring 8a.
  • Figure 1 shows a first version of the spring consisting of a wire spring 19 with an open circular shape.
  • the spring 19 is inserted between the contact ring 8a and the body 5 which has a seat 20 to house it.
  • the spring 19 also has two radial projections 19a and 19b projecting outwards from its circumference, at the corresponding free ends, and making contact with two opposite surfaces of a ring 8a semi-circular inner bulge 21: in this way rotation of the handgrip 7 and the ring 8a compress the spring 19 which, as a result, generates a counterthrust when the pressure on the handgrip 7 ends, causing the handgrip to return to the closed position.
  • the elastic means 8 comprise two wire springs 22, 23, each omega-shaped and inserted between the contact ring 8a and the body 5 having the relative seat 20 to house them.
  • the elastic means 8 comprise two helical springs 24, 25, inserted between the contact ring 8a and the body 5 having a relative seat 26 to house them.
  • the two helical springs 24, 25 are positioned opposite each other to form a sort of ring in the body 5, and their free ends make contact on both sides with the surfaces of corresponding contact ring 8a radial bulges 8c, 8d: again, operation is as described for the two previous embodiments.
  • the handle structured in this way achieves the preset aims, through the insertion in the handgrip connecting and positioning mechanism of a retaining element, already present and fitted in the handle set, designed to connect, in a releasable fashion, the handgrip on the body and on the square shaft even if the locking grub screw is not present, or if the grub screw, for various reasons, does not secure the handgrip to the shaft: thus preventing the handgrip from becoming detached.
  • Said device is economically acceptable, leaves the dimensions of the handle body unchanged and is already integrated with the body and the spring means during the pre-assembly step, therefore without additional operations for the fitter.
