Abstract
Description
[0001] This invention relates to a door or window frame comprising a system for locking a handle which can be associated with it. In particular, without limiting the scope of the invention, the invention may be applied in the technical field of doors and windows provided with an electric actuator for an automatic opening and closing of the mobile frame relative to the fixed frame.
[0002] In the doors and windows with an electric actuator, the user can open the door or window manually to perform, for example, cleaning or maintenance operations.
[0003] The manual actuation comprises the use of a handle which may be associated or associable with the mobile frame in such a way that the user can control the closing or opening, of a side hung or tilt and turn type, of the mobile frame relative to the fixed frame by a relative rotation of it with respect to a pivot.
[0004] As is known, the handle comprises a control pin having a prismatic cross-section which allows operating means positioned in the door or window to be operated to determine the closed or open configuration of the movable frame.
[0005] The handle is like a rigid lever fixed to the pin. To rotate it, the user applies a tangential force at a certain distance from the pin, the center of rotation (the force is between 10 and 20 N).
[0006] The applied force generates a torque that is transmitted to the internal mechanism to activate the operating parts.
[0007] The mobile frame of the door or window has a hole for housing the control pin of the handle through which the pin is inserted or removed by the user. A disc for covering the hole is hinged close to it for concealing it if the handle is removed from the door or window.
[0008] In use, the prior art handle has a main drawback, that is to say, the pin, although inserted in the housing hole, during the rotation of the handle tends to come out since it is free to translate in the hole.
[0009] Not only that, since the pin of the handle is in no way constrained to remain inserted in the hole, the user is free to remove the handle from the door or window in any position it is, also in a position corresponding to an open configuration of the door or window, side hung or tilt and turn.
[0010] This could adversely affect any automatic operation of the door or window since the operating means are positioned incorrectly relative to the movement of the components actuated by the electric actuator.
[0011] In this context, the need has been felt of developing a system for locking a handle which can be associated with a door or window which allows it to be inserted and removed from the door or window only in a defined position, with the door or window closed, and to retain it during its rotation in the door or window.
[0012] Said aim is fully achieved by a door or window frame comprising a system for locking a handle which can be associated with it as described in independent claim 1.
[0013] Further features of the invention are described in the accompanying dependent claims.
[0014] The advantages of the invention are more apparent in the non-limiting description which follows of a non-exclusive embodiment of a system for locking a handle which can be associated with a door or window as illustrated by way of example only and, therefore, without limiting the scope of the invention, in which: Figure 1 illustrates a door or window frame in which a system is applied for locking a handle which can be associated with it according to the invention; Figure 2 illustrates a detail of the locking system of Figure 1 with the handle at 0°; Figure 3 illustrates a detail of the locking system of Figure 1 with the handle at 90°; Figure 4 illustrates a detail of the locking system of Figure 1 with the handle at 180°; Figure 5 illustrates a schematic perspective view of a component of the locking system; Figure 6 illustrates an alternative embodiment of a portion of the door or window of Figure 1; Figure 7 illustrates a perspective view of a detail of Figure 6; Figures 8 to 10 illustrate a piece of the mobile frame of the door or window of Figure 1 wherein the handle is in position at 0°, 90° and 180°. With reference to the accompanying drawings, the numeral 1 denotes a system for locking a handle 2 which can be associated with a door or window frame 3 according to the invention.
[0015] The door or window frame 3 comprises a fixed frame 4 and a mobile frame 5 configured to pass from a closed configuration to an open configuration in relation to the relative position between the mobile frame 5 with respect to the fixed frame 4.
[0016] The handle 2 comprises a pin 6 for controlling the operating means 7 for forming the closed or open configuration of the mobile frame 5 with respect to the fixed frame 4.
[0017] The door or window frame 3 according to a variant embodiment is provided with an electric actuator 20 for forming a tilt and turn opening of the mobile frame 5 with respect to the fixed frame 4 and a consequent closing.
[0018] According to this variant embodiment, the rotation of the handle from 0°, Figure 8, to 180°, Figure 10, controls a hinged opening of the mobile frame 5 with respect to the fixed frame 4.
[0019] According to a variant embodiment wherein the door or window frame 3 does not have an electric actuator 20, the rotation of the handle from 0°, Figure 8, to 180°, Figure 10, controls a tilt and turn opening of the mobile frame 5 with respect to the fixed frame 4.
[0020] According to a further variant embodiment, the rotation of the handle from 0°, Figure 8, to 90°, Figure 9, controls a hinged opening of the mobile frame 5 with respect to the fixed frame 4.
[0021] The control pin 6 comprises a tab 10 positioned at the end of it. Preferably, the tab 10 is of the straight type, with a rectangular cross section.
[0022] The locking system 1 comprises a seat 8 in which the control pin 6 of the handle 2 can be inserted and the control pin 6 can be rotated in the seat 8. According to this invention, the seat 8 has a recess 9 configured for inserting the tab 10 of the control pin 6.
[0023] The recess 9 is shaped to match the shape of the tab 10.
[0024] According to this variant embodiment, the recess 9 has a rectangular shape.
[0025] The locking system 1 comprises a guide element 12 configured for guiding, in use, the tab 10 of the control pin 6 starting from the recess 9 to an end of stroke 11.
[0026] The guide element 12 defines a feed path of the tab 10 during rotation of the control pin 6 in the seat 8 from the recess 9 to the end of stroke 11, and vice versa.
[0027] The guide element 12 extends circumferentially from the recess 9 to the end of stroke 11 in such a way that the end of stroke 11 is positioned at 180° with respect to the recess 9.
[0028] According to a variant embodiment not illustrated, the guide element 12 extends circumferentially from the recess 9 to the stroke end 11 in such a way that the end of stroke 11 is positioned at 90° with respect to the recess 9.
[0029] Therefore, in that alternative embodiment the opening of the mobile frame 5 with respect to the fixed frame 4 is achieved at 90°.
[0030] With reference to the guide element 12 it should be noted that further features described below apply both in the embodiment illustrated wherein the end of stroke is at 180° and in the variant not illustrated wherein the end of stroke 11 is at 90° from the recess 9.
[0031] This is because the tab 10 of the control pin 6 can be inserted in the recess 9 and can be removed from the recess 9 only in the closed configuration of the door or window frame 3, position 0° of the handle as illustrated in Figure 8.
[0032] By means of a rotation of 180° from the position for inserting the tab 10 in the recess 9, the handle 2 controls an opening of the mobile frame 5 with respect to the fixed frame 4.
[0033] As mentioned, the opening which can be achieved by a rotation of 180° may be considered as a side-hung or tilt and turn opening, 180° position of the handle as illustrated in Figure 10.
[0034] It should be noted that although reaching the end of stroke position at 180° according to this embodiment there is also the possibility of rotating the handle by 90° and actuating a further opening of the mobile frame 5 relative to the fixed frame 4.
[0035] In order return the mobile frame 5 to the closed position with respect to the fixed frame 4, a rotation of 180° is required in the opposite direction to the previous one, from the end of stroke 11 to the recess 9.
[0036] In order to retain in position the handle 2 rotated by 180°, the guide element 12 has an increasing inclination from the recess 9 at the end of stroke position 11 in such a way as to lock by interference the tab 10 of the control pin 6 at the end of stroke 11.
[0037] The guide element 12 is in the form of a track the head surface 12a of which is intended to come into contact with the tab 10 of the control pin 6. The top surface 12a of the track 12 has an increasing inclination from the recess 9 at the end of stroke 11 for gradually engaging the tab 10 by interference.
[0038] Vice versa, the top surface 12a of the track 12 has a decreasing inclination from the end of stroke 11 to the recess 9 for gradually disengaging the tab 10.
[0039] The locking system 1 has a side wall 13 which extends from the recess 9 to the end of stroke 11 at which the side wall 13 defines the end of stroke 11.
[0040] The side wall 13 comprises a circumferential portion which runs alongside the guide element 12 and a portion transversal to the circumferential portion which defines the end of stroke 11.
[0041] The locking system 1 comprises an element 14 for covering the seat 8 which can engage in the seat 8 in place of the handle 2.
[0042] The covering element 14 has a top wall 15 and an inner wall 16, opposite the top wall 15.
[0043] If the covering element is engaged in the seat 8, the top wall 15 is visible from the outside.
[0044] The covering element 14 comprises a pin 17 with the tab 18 extending from the inner wall 16.
[0045] The tab 18 of the pin 17 can be inserted in the recess 9 and can rotate in the seat 8 along the feed path of the guide element 12 up to the end of stroke 11, and vice versa, from the end of stroke 11 up to the recess 9. The pin 17 is positioned on a supporting step 19 which defines with the tab 18 of the pin 17 a gap which can be engaged by the guide element 11. With reference to the covering element 14, the tab 18 of the pin 17 can be inserted and removed with respect to the recess 9 and remains retained in the seat 8 by the guide element 12 following a rotation of 180°, or 90° with reference to the alternative variant embodiment, to bring the tab 18 to the end of stroke 11.
[0046] During this rotation, the gap between the supporting step 19 and the tab 18 engages with the guide element 11 up to the end of stroke 11 in which it reaches an interference position.
[0047] In order to return the tab 18 from the end of stroke 11 to the recess 9 it is necessary to rotate the covering element 14 by 180°, or by 90° with reference to the alternative variant embodiment, in a direction opposite to the previous one.
