- the handle body 2 also houses a pinion 9 integral with the shaft 6 and connected to an element 10 which supports, connects and drives the control parts 7 in such a way as to allow the control parts to move to several positions corresponding with the above-mentioned operating conditions of the grip 5, respectively corresponding with closing, turning opening, even outwards, and tilting opening of the door or window.
- the handle body 2 has a base element 11, which has a guide opening 12 from which there project the control parts 7 and which is normally a cover that can be attached to the handle body.

- the bar 13 has a pawl 14, fixed at one end and rocking, thanks to means 15, in a direction perpendicular to the plane of the bar 13 in such a way that it assumes a locking position, following a connection inside a relative seat 16 in the base element 11, when the door or window is in the open configuration, that is to say, with the first part 3 distanced from the second part 8 of the door or window (see Figure 3), and, respectively a bar 13 release position, when the door or window is in the closed configuration, that is to say, with the first part 3 close to the second part 8 (see Figures 2 and 9).

Abstract
Description
- The present invention relates to a multi-purpose cremone bolt handle for doors and windows, in particular metal doors and windows.
- Known cremone bolt handles comprise a handle body (normally quadrangular or with rounded corners), from which there extend, on one side the operating grip and, on the other side the parts designed to operate the door or window closing device.
- This basic structure gave rise to a series of models of cremone bolt handles (for example, patent EP - 446.566, Utility model IT - 227.820 and the application for a patent for a utility model BO94U000059, all by the Applicant) with the aim of diversifying the uses of the cremone bolt handle according to the door or window requirements: multi-purpose or bilateral handle (turning to the right, turning to the left), handle with lockable grip, handle for tilting windows, etc.
- However, the huge commercial expansion of these handles necessitated further embodiments, including a cremone bolt handle for tilt and turn operation (with incorrect movement safety device), with the possibility of left-turning and right-turning use, as well as for outward-opening doors and windows, where it is essential that the external dimensions of the handle are limited, but where the bolt must retain a high level of efficiency and reliability even for the other functions mentioned above.
- Such characteristics are not easily obtained, since the size of the control parts for opening and closing, both with a turning action and a tilting action, and the relative travels necessary to obtain such configurations are not, at present, possible with the handle external dimensions required for outward-opening doors and windows.
- However, the Applicant has created a cremone bolt handle with all of the above-mentioned characteristics, that is to say a handle which is extremely compact, with reduced external dimensions, and which can be used on outward-opening doors and windows, and, if necessary, can perform all of the movements required for opening with a turning action, with a tilting action, etc.
- The technical features of the present invention, in accordance with the above aims, are apparent in the claims herein, and the advantages are more clearly described in the detailed description below, with reference to the accompanying drawings, which illustrate an embodiment of the invention, without limiting the scope of its application, and in which:

- Figures 12, 13 and 14 are, respectively, a bottom plan view, a side view and a top plan view of another detail of the embodiment in Figure 10, that is to say, a handle locking - release bar.
-
- With reference to the accompanying drawings, and in particular Figures 1 and 9, the cremone bolt handle disclosed is used on metal doors and windows, such as French windows and windows, the latter in particular having a closing configuration, a turning opening configuration and a tilting opening configuration, with outward opening from the room in which they are fitted.
- This handle, indicated as a whole with the
numeral 1, comprises ahandle body 2 attached to afirst part 3, or wing, of the door or window and from which there extend, on one side with abushing 4 made so that it forms a single body with thehandle body 2, agrip 5 designed to turn ashaft 6 housed inside thehandle body 2, through several stable operating positions, set at right-angles to one another. From the other side of thehandle body 2 there extendcontrol parts 7 connected to a device for closing the door or window (of the known type and, therefore, not illustrated) with a closing configuration in which thefirst part 3 makes contact with asecond part 8 of the door or window (illustrated only with a dashed line in Figure 2 and more clearly visible in Figure 9; thesecond part 8 may be the fixed frame or the other wing of a window). - The
handle body 2 also houses apinion 9 integral with theshaft 6 and connected to anelement 10 which supports, connects and drives thecontrol parts 7 in such a way as to allow the control parts to move to several positions corresponding with the above-mentioned operating conditions of thegrip 5, respectively corresponding with closing, turning opening, even outwards, and tilting opening of the door or window. - The
handle body 2 has abase element 11, which has a guide opening 12 from which there project thecontrol parts 7 and which is normally a cover that can be attached to the handle body. - The above-mentioned
control parts 7 consist of anactuator bar 13, projecting from the opening 12 in thebase cover 11 and normally attached in such a way that it is integral with a corresponding rack defining the above-mentionedelement 10 for supporting, connecting and driving the bar. - The
bar 13 has apawl 14, fixed at one end and rocking, thanks to means 15, in a direction perpendicular to the plane of thebar 13 in such a way that it assumes a locking position, following a connection inside arelative seat 16 in thebase element 11, when the door or window is in the open configuration, that is to say, with thefirst part 3 distanced from thesecond part 8 of the door or window (see Figure 3), and, respectively abar 13 release position, when the door or window is in the closed configuration, that is to say, with thefirst part 3 close to the second part 8 (see Figures 2 and 9). - As illustrated again in Figure 1, the
base element 11, as already indicated, consists of a cover which can be fixed to thehandle body 2, by snapping into place or using screws, and has a guide opening 12 with threeseats 16 composed of relative lateral openings, one after another and corresponding with the above-mentioned three operating positions which can be assumed by thegrip 5. Eachseat 16 has a width L greater than the width L1 of thepawl 14. - The
cover 11 also has a pair of secondindependent openings 12a if the handle is designed for use on interior doors and windows with a tilt and turn action which envisage the known pair of bars with relative racks (of the known type and, therefore, not illustrated). - The
pawl 14 consists of a plate engaged in amatching slot 17 made in thebar 13 in such a way that it defines part of the latter. - Close to the free end of the
bar 13, theslot 17 has acrosspiece 18 which is partially surrounded by a "C"-shaped portion 14a of theplate 14, defining a pivoting point for plate rocking. In addition, thebar 13 has aretaining notch 19 for the end section of theplate 14 located between thecrosspiece 18 and the end section of thebar 13. - Figures 10 to 14 illustrate another embodiment of the pair of elements consisting of the
bar 13 and theplate 14. - In particular, this embodiment tends to improve the efficiency of the
plate 14 as it moves from the lowered position (also visible in Figure 10) to the raised position (see Figure 3). - The pawl 14 (clearly visible in Figures 12 to 14) consists of a plate which yields elastically and pivots, with its
portion 14b, at thefree end 13a of thebar 13 to define the central part, open at the centre. Theportion 14b of theplate 14 has a "C"-shaped cross-section, so that it completely surrounds thefree end 13a of thebar 13. - Moreover, the
plate 14 has aslot 14c in theportion 14b (that is to say, extending substantially in a "C"-shape), one side of which makes contact with a correspondingretaining projection 13b, close to thefree end 13a of thebar 13. This connection (clearly visible in Figure 10) allows the definition of a mobile pivoting zone (see arrow F14c) for theplate 14, designed to allow rotation - translation of the plate when the door or window is in the open and, respectively, closed configurations. - In other words, the
plate 14 is not simply housed in thebar 13 in a matching fashion and subject to the action of the drive means 15, but is itself an active element in the drive system: the elasticity of theplate 14, together with the connection and pivoting zone at the end of thebar 13, allow the plate to move safely from thehandle 1 release position (door or window closed position), to thehandle 1 locking position (door or window open position, see also arrow F8), an operation which is described in more detail below below, after the description of the drive means 15. - As is also illustrated in Figures 2 and 3, the above-mentioned
pawl 14 drive - rocking means 15 consist of aleaf spring element 20, which yields elastically. - More precisely, the
leaf spring element 20 has the shape of an inverted "U", designed to define a pair ofarms first arm 21 can be attached to thepawl 14, using relative screw means 23, whilst theother arm 22, projecting relative to thebar 13, is designed to intercept thesecond part 8 of the door or window (see Figure 2) so as to allow, through elastic deformation of botharms 21 and 22 (see arrow F), the passage of thepawl 14 from the locking position to the release position. - As illustrated in Figure 1, the
first arm 21 consists of acentral portion 21a, directly connected to thepawl 14, and the same size as the pawl. There are twolateral tabs central portion 21a, said tabs defined by corresponding notches made in thefirst arm 21, designed to adhere to thebar 13 and, together with the elastic return of theentire leaf spring 20, allow the passage from the release position to the locking position (see Figure 3), when the twoparts tabs projections 33 designed to make contact with thebar 13. - The above-mentioned
second arm 22 also has anend projection 24, the surface of which is rounded in such a way as to allow its contact with thesecond part 8 of the door or window and the recovery of any play between the two parts of the door or window and in thehandle 1 closing mechanisms. - In the embodiment illustrated in Figures 10 to 14, as already indicated, the passage from the
handle 1 release position to the locking position is effected with the combined action of theleaf spring element 20 and thepawl 14 which, thanks to the fact that it pivots at the end of thebar 13, tends to rise to said position autonomously. - The details in Figures 6 and 7 illustrate the particular structure and shape of the
teeth 10d of therack 10, which are independent of one another and offset from the base of the rack. Saidteeth 10d, together with thepinion 9, allow thebar 13 to move in both directions. This particular profile of theteeth 10d allows a movement of thebar 13 which exceeds the actual travel generated by the meshing of the teeth of thepinion 9 and those of therack 10, since the meshing of each pair of teeth is preceded by an additional thrust in the direction of feed (cam-style), on therack 10 given by the previous meshing. This factor means that the size of the elements can be restricted, but at the same time allows abar 13 travel identical to that traditionally used on bigger cremone bolt handle models, allowing both turning and tilting opening. - As can be seen in Figures 1 to 3, between the
toothed pinion 9 and screw means 9v which attach the pinion to the rotatingshaft 6, there may be abushing 50 which has a hollow 51 designed, if the pair of bars are used as control parts, to hold the bars, in a preset position, inside thehandle 1 during the assembly stage, that is to say, when thecover 11 has still not been fitted. - Another addition to the construction of the
handle 1 is illustrated in Figure 8, which shows thehandle 1 disclosed with a pair of plugs T designed to cover through-seats which house the means for attaching thehandle 1 to the door or window. - Figures 4 and 5 illustrate a model of the
handle 1 withparts 25 for locking thegrip 5 with a key C. - These key-operated
locking parts 25 consist of a key-lockingcylinder 26 housed in thegrip 5 and having, on one side, aseat 26a in which the key C engages, and on the other, locking means 27 which prevent rotation of thegrip 5, acting between the grip and thebushing 4. - These means 27 are positioned parallel with and close to an axis of rotation X of the grip coinciding with the above-mentioned
rotating shaft 6. - More specifically, the locking means 27 consist of a
face cam 28 with a concave profile, caused to rotate directly by the key C. - The
face cam 28 acts upon apin 29 which has ahead 30 for contact with the cam and is housed in a through-seat 5a in thegrip 5. In this way, thepin 29 can be made to slide between a non-operating position (see Figure 4), in which thepin 29 is drawn back inside thegrip 5, and an operating position (see Figure 5), in which thepin 29 is partially outside thegrip 5 and engages in aseat 31 in thebushing 4, preventing rotation of thegrip 5. - The
pin 29 has spring means 32, fitted over it and held, at their ends, by theseat 5a in thegrip 5 and by thecontact head 30, which cause thepin 29 to return from the operating position to the non-operating position when the key C is turned (see arrow F32). - A handle thus structured, therefore, fulfils the aims thanks to a structure which provides extremely reliable operation, is more compact but very flexible in terms of use, that is to say, with all of the technical and operating characteristics of conventional cremone bolt handles currently on the market and with further possibilities for use on outward-opening doors and windows without requiring changes to the handle body.
- The reduction in size was achieved thanks to the particular construction of the rack, the structure of the control parts (bar - pawl - leaf spring) which, in a limited space, allow all drive movements required for the wing open or closed configurations, avoiding the known problem of incorrect movements with the wing open. This, as indicated, is all provided by a cremone bolt handle made compact so that the handle can be used on outward-opening doors and windows.
- The key locking system is also made using very small control parts, to avoid unattractive effects (thanks to the closeness of the locking system to the axis of rotation of the grip), but maintains a high level of efficient and reliable closing.
- In practice, a complete cremone bolt handle is provided which, with a kit consisting of a limited number of accessories, can be mounted on any type of door or window by selecting the appropriate accessories and without working on the handle body, assembly of the accessories being extremely simple. The invention described can be subject to modifications and variations without thereby departing from the scope of the inventive concept.
