Description

TECHNICAL FIELD

[0001] The present invention relates to an operating device for doors and windows, in particular made of metal or PVC, etc.

[0002] In particular, the present invention is applicable to doors and windows having a traditional leaf-type opening which in some cases also requires having a key-type closing device. BACKGROUND

[0003] The operating devices currently used for doors and windows are necessary for moving suitable devices to lock the leaf with respect to the fixed frame of the window; all this is controlled by an external handle.

[0004] The operating device essentially comprises:

[0005] - a box-like body which can be associated with or housed in the upright of the leaf;

[0006] - a kinematic unit (partially rotating toothed-rack unit) for operating the locking device housed in the box-like body.

[0007] The kinematic unit, in particular the toothed wheel (by shaft), is connected to an external handle or grip which protrudes outside the leaf.

[0008] The locking device is slidably mounted on the leaf and comprises one or more rods inserted into suitable channels made in the profile of the leaf. The rods have associated with them a protruding pin and / or boss (in the case of the pin, protruding from the end of the rod, or in the case of the boss, protruding transversely from the rod), designed to obstruct or not obstruct a corresponding contact element made or installed on the fixed frame.

[0009] These slidable rods are connected to the ends of the toothed rack of the above-mentioned operating device (protruding from both sides of the box-like body) so that the rotation of the partially toothed wheel transmits the movement to the toothed rack to achieve the linear movement of the rods connected to it, thus achieving the opening and closing positions of the leaf-type, transom-type.

[0010] In other words, by acting on the handle or grip (by its rotation), it is possible to switch the locking device from a closed configuration in which the leaf is rigidly fixed to the fixed frame and cannot be moved to a first open configuration in which the leaf is disengaged from the fixed frame and can be opened to a first leaf-type position (handle rotated by 90°) and a subsequent second transom-type opening position (handle further rotated by 90°). Reversing the rotation of the handle by 180° returns the leaf to the closed configuration.

[0011] To obtain these openings, the toothed wheels have a toothed circumference extension around the surface of the wheel, of 180°, on which the openings are obtained, thus generating the movement of the racks which, in turn, are able to pull or push the rods with the equivalent rectilinear extension of their teeth.

[0012] This operating device, now very widespread, has many advantages, including the possibility of being used for various types of profile sections of reduced size present on the market, and high reliability over time.

[0013] At present, there is a specific need on the market for doors and windows, due to the presence of the traditional requirement of the door and window type opening with only the mobile leaf and also the need for greater security of the door or window by applying the lock with a key.

[0014] For this need, the operating device as described above would be optimal due to its overall size and reliability, but given the intrinsic technical structure which leads to a longer operating stroke of the toothed wheels - racks and therefore of the closing device in the various positions, it cannot be used.

[0015] Therefore, the operating device constructed in this way cannot be used for this specific operating need of doors or windows.

[0016] Therefore, this specific limitation makes it difficult to rationalize the limitation of the number of components of the operating device, the constant maintenance of optimal control operability and, above all, the limitation of the number of models and components required according to the various operating requirements on the market, which in fact would increase the production and storage costs of the companies that produce such fittings.

[0017] In fact, in the patent documents EP2784248, GB2399596, EP1008710 and EP1445407, solutions of operating units are known in which for this purpose a box-shaped body for the gearwheel is constructed, i.e. with a shape of protrusions or counter-teeth which are able to hinder the rotation of the gearwheel at specific points. SUMMARY

[0018] The aim of the present invention is to provide an operating device for doors and windows which overcomes the above-mentioned drawbacks of the prior art.

[0019] In particular, the aim of the present invention is to provide an operating device for doors and windows which can be installed on doors and windows in different opening modes without the need for structural modifications to the device.

[0020] Said aim is fully achieved by the operating device according to the present invention, as characterised in the appended claims. BRIEF DESCRIPTION OF DRAWINGS

[0022] - Figure 1 is a partial exploded perspective view of the operating device according to the application applied to a movable frame or door leaf, in which some parts are cut away to better illustrate others;

[0023] - Figure 2 shows Figure 1 a perspective view of the operating device;

[0024] - Figure 3 is a side view of the operating device of the previous figure, in which some parts are cut away to better illustrate others;

[0025] - Figure 4 and Figure 5 show, in two different operating configurations, the operating device of Figure 3 . DETAILED DESCRIPTION

[0026] With reference to the accompanying drawings, and in particular to Figure 1 , the operating device according to the application is suitable for being applied to a door and window, for example comprising a fixed frame (not shown) and a movable frame or door leaf 1.

[0027] The operating device 100 comprises a box-like body 2 shaped to match the housing in the seat of the door leaf 1 (see Figure 1 , in which the operating device is housed in the channel of the profile inside the upright of the door leaf 1).

[0028] The operating device 100 also comprises a wheel 3 having a first circular segment 3a with a smooth surface and a second circular segment 3b with teeth housed in the box-like body 2.

[0029] The wheel 3 has a coupling seat 4 able to engage, in use, with the shaft 5 of a control grab 6 associated with the movable door leaf 1. The shaft 5 of the grab 6 is coupled with the wheel 3 passing through the box-like body 2 having a corresponding seat 7.

[0030] The operating device 100 comprises a rod 8 slidably inserted in the box-like body 2 and having an end portion outside the box-like body 2 configured, in use, to be connected to the closing / opening device (not shown) of the movable door leaf 1 located on the door leaf 1.

[0031] The lever 8 has an associated surface equipped with an operating rack 9 which meshes with the toothed second circular segment 3b of the wheel 3, thus allowing the sliding of the lever 8 by rotating the wheel 3 (under the action of the handle 6), which makes it possible to obtain, starting from the closed position of the door leaf 1 on the fixed frame, in succession, a first open position of the door leaf 1 from the fixed frame (first rotation of 90°) and a second open position of the door leaf 1 with respect to the fixed frame (total of 180°) with further rotation of 90° of the handle 6, different from the previous first open position.

[0032] Depending on the type of mechanism present on the door leaf 1 (and, if necessary, on the type of handle 6), the first opening available can be of the traditional door leaf type, while the second opening can be of the transom type.

[0033] For other types of mechanisms present on the door leaf 1, the first opening can be of the transom type, while the second opening can be of the traditional door leaf type.

[0034] These configurations do not limit the scope of protection of the present application.

[0035] In other words (see also Figure 4 ), the wheel 3 has a toothed second circular segment 3b which extends along the wheel 3 for an arc of more than 180°.

[0036] In this way, the rotation of the wheel 3 allows the sliding of the lever 8 (in both directions and thanks to the rack 9) and moves the closing means (for example, pins and / or bosses) from the closed position of the door leaf 1 (in which the pins and / or bosses are in contact with the contact elements present in the fixed frame) to the first open position, for example, of the traditional door leaf type (or transom type) or even to the second position of the transom type opening (or door leaf type opening) of the movable door leaf.

[0037] In the case of the door leaf type opening, the pins and / or bosses are moved away from the contact elements, while in the case of the transom type opening, the pins and / or bosses are positioned to drive the upper operating arms of the movable door leaf to obtain this type of opening.

[0038] The rotation of the handle 6 in the opposite direction determines the reverse of the above-described configuration of the movable door leaf 1.

[0039] As shown (see Figures 2 to 5 ), the operating device 100 comprises a slider 10 for selecting and locking the wheel 3, which can be stably inserted inside the box-shaped body 2 through a first through seat 11 made on the box-shaped body 2.

[0040] The slider 10 is movable with respect to the wheel 3 (see Figures 2 to 4) radially and can be positioned so as to hinder the rotation of the wheel 3 by abutment against a first tooth 12 of one end of the toothed second circular segment 3b and thus limit the rotation of the wheel 3 only between the closed position of the leaf 1 and a single open position of the leaf 1 between the first open position and the second open position (and vice versa).

[0041] In this way, if a single opening is chosen for the installed movable leaf 1, the rotation of the wheel can be limited only by 90°.

[0042] Preferably, this limitation of rotation determines only the traditional leaf-type opening of the door or window (in fact preventing the possibility of transom-type opening).

[0043] This does not mean that, for other reasons, the choice of single opening can be designed only as a transom-type opening, preventing the traditional leaf-type opening, thus not limiting the scope of protection thereby.

[0044] This solution can have a single type of operating device that can be used for both types of opening for which it is designed, but is limited to a single opening if necessary, since only the addition of the slider is added when assembling the device.

[0045] It is specified that the box-like body 2 has a second seat 13 in which the slider 10 for selection and locking can be selectively housed.

[0046] In this case, the slider 10 can be positioned radially with respect to the wheel 3 and hinder the rotation of the wheel 3 by contact with a second tooth 14 of the opposite end of the toothed second circular segment 3b opposite the first end tooth 12 previously mentioned.

[0047] This addition is designed to allow the selection of a single opening (for example, traditional leaf-type) depending on the opening direction of the movable leaf (that is, right or left opening direction, thus reversing the rotation direction of the wheel).

[0048] Preferably, the slider 10 comprises a contact body 15 that can be housed in the box-like body 2 for contact with the wheel 3, and a grip 16 positioned outside the box-like body 2 when in use.

[0049] In this regard, the contact body 15 comprises a straight surface 17 designed to come into contact with the surface of the first end tooth 12 or of the second end tooth 14 of the wheel 3, and a head end 18 having a curved surface that can face a portion of the first circular segment 3a, shaped so as to match the smooth surface of the wheel 3 close to the first end tooth 12 or to the second end tooth 14.

[0050] It should be noted that the operating device 100 comprises fixing means for fixing the slider 10 to the box-like body 2 when the slider 10 is positioned inside the box-like body 2.

[0051] In view of this, the fixing device comprises a fixing screw 19 which passes through the hole 20 in the box-like body 2 and which can be coupled into a seat 21 made in the slider 10 housed in the box-like body 2, thus locking the position of the housed slider 10.

[0052] In this way, the position and stability of the slider inside the box-like body are ensured.

[0053] It is specified that the slider 10 is equipped with a seat (21) for fitting into the contact body 15.

[0054] Briefly, the operating device thus configured can be installed without modifications to operate the door leaf through two different openings thereof, while, when a single opening is required (typically of the conventional door leaf type, but without limiting the scope of the present application), the slider can be inserted to select only the rotating part of the gear (limited angle), thus operating a single opening.

[0055] The operating device thus configured fully achieves the intended purposes.

[0056] Since the slider can be inserted to limit the opening, it is possible to operate a single opening without having to change the internal components of the device, which would be a costly operation.

[0057] The single mode of the operating device is thus maintained.

[0058] The selection mode of the operating device is simple, low cost and highly reliable.
