Definitions

• the present invention relates to a handle assembly for a movable element, in particular a door or a window.
• the assembly according to the present invention is therefore usable for assembly on doors, windows, window frames or the like in civil construction or furnishing.
• handle systems for opening doors consist of a pair of handles, a pair of plates that may or may not accommodate a return mechanism, and a handle frame that has the function of allowing the lock to be operated. Examples of such handles are shown in publications US 2014/159392 A1 , FR1424542 A and EP 1882798 A1 .
• This assembly comprises a handle that is fixable to one of the side surfaces of the door.
• a second element for example a second handle, is fixable to the other side surface of the door and is connected to the handle by a pin, in such a way that it rotates integrally around an axis of rotation.
• a ball bearing is disposed between the handle and the door to facilitate the rotation of the handle.
• WO' 102 The solution of WO' 102 is characterized by the fact that it does not have a washer, therefore the bearing is placed directly in contact with the door. The handle is then assembled so as to retain the bearing in position by the tightening force between the handle and the door, without any other type of constraint.
• handles of the type described in WO' 102 may present some reliability problems.
• the installation is not carried out correctly, or if the underlying door has some imperfections, it is not certain that simple tightening will be able to retain the bearing in position for an extended period of time. If the tightening is not sufficient, or if it fails, the bearing may become labile and possibly be subject to displacements with respect to the assembly position.
• the technical task underlying the present invention is to propose a handle assembly for a movable element, in particular a door or a window, that overcomes the drawbacks of the above-mentioned prior art.
• a handle assembly for a movable element in particular a door or a window, comprising the technical characteristics set forth in one or more of the attached claims.
• a handle assembly in accordance with the present invention is suitable for being installed on a movable element, such as for example a door or a window.
• the movable element has a pair of opposite side surfaces.
• the assembly comprises a handle that is fixable to one of the side surfaces of the movable element.
• a second element for example a second handle, that is fixable to the other side surface of the movable element and is connected to the handle to rotate integrally around an axis of rotation.
• Friction reduction means are associated with the handle and/or the second element to facilitate the rotation of the handle and/or the second element with respect to the movable element.
• the assembly further comprises at least one plate, which is configured to be fixed directly to the movable element.
• the friction reduction means are active between the handle and/or the second element and the plate.
• This device solves the technical problem, since the plate, by adhering itself to the door, does not need to be held in position by the tightening of the handle. As a result, the assembly is more stable and less prone to displacement, even with lighter tightening.
• the tightening force required to assemble the assembly is very low. Therefore, the door on which the assembly is mounted is subject to less risk of damage during installation.
• the number 1 indicates a handle assembly for a movable element 100 in accordance with the present invention.
• the movable element 100 may be, by way of example only, a door, window, fixture, or the similar element.
• the movable element 100 has a pair of side surfaces 101, opposite each other, and separated by a thickness "T".
• a through hole 102 is obtained on the movable element 100, in such a way as to allow the installation of the assembly 1 as will be better specified in a later part of the present description.
• the movable element 100 is itself known to the person skilled in the art, and will therefore not be described further.
• the movable element 100 will be identified with a door, without however losing generality.
• the assembly comprises a handle 2 which can be fixed to one of the side surfaces 101 of the movable element 100.
• a second element 3 may be fixed to the other side surface 101 of the movable element 100.
• the second element 3 is also connected to the handle 2, in such a way as to rotate integrally with it about an axis of rotation "A".
• the second element 3 is defined by a second handle, identical to the handle 2.
• a pin 6 connects the handle 2 and the second element 3.
• the axis of the pin 6 defines the aforementioned rotation axis "A”.
• the handle 2 comprises a grip 4, which is configured to be arranged substantially parallel to the side surface 101 of the movable element 100.
• the handle 2 further comprises a neck 5, fixed to the grip 4.
• the neck 5 is fixed integrally to the pin 6, so that a rotation of the handle 2 is transmitted to the pin 6 and to the second element 3.
• Other mechanisms may be associated with the pin 6, by way of example only a latch (not illustrated). Such mechanisms will not be described as not being part of the present invention.
• the assembly 1 comprises friction reduction means 7, which are associated with the handle 2 and/or the second element 3, in such a way as to facilitate the rotation of the handle 2 and/or the second element 3.
• the friction reduction means 7 are defined by at least one bearing 8, preferably a ball bearing. If two handles are present, as shown for example in Figure 1 , each handle is associated with a respective bearing 8.
• the assembly 1 comprises at least one plate 9, also known in the technical jargon of the sector as an escutcheon, which is configured to be fixed directly to the movable element 100.
• the friction reduction means 7, i.e. the bearings 8, are active between the handle 2 and/or the second element 3 and the movable element 100.
• the plate 9 has an outer surface 10 which, in use, faces the handle 2 and/or the second element 3.
• the plate 9 is provided with a central through hole 12 which, in use, is positioned at the hole 102 of the movable element 100.
• the neck 5 of the handle 2 has a section "S" transverse to the axis of rotation "A", which has substantially the same shape as the plate 9.
• both the plate 9 and the section "S" of the neck 5 have a square shape.
• both the plate 9 and the section "S" of the neck 5 are circular in shape.
• the section "S" of the neck 5 has a first perimeter 15.
• the plate 9 has a second perimeter 16.
• the first perimeter 15 is parallel to the second perimeter 16, or is coincident with it. If the two perimeters 15, 16 are not coincident, the distance between them is less than 1.5 mm.
• the second perimeter 16 encloses the first perimeter 15.
• the friction reduction means 7 mentioned above are configured to be arranged between the neck 5 of the handle 2 and the plate 9.
• the plate 9 has a seat 17, which is arranged to house the bearing 8.
• the seat 17 is counter-shaped to the bearing 8.
• the neck 5 of the handle 2 may have a further seat 18, also counter-shaped to the bearing 8.
• the further seat 18 is arranged to face the seat 17 of the plate 9, and is also arranged to house the bearing 8 at least in part.
• the two seats 17, 18 firmly lock the bearing 8 in the assembly phase of the assembly 1.
• the assembly 1 comprises a fixing layer 13.
• This fixing layer 13 is in particular arranged on the plate 9, in particular on the inner surface 11.
• the fixing layer 13 has the function of adhering to one of the side surfaces 101 of the movable element 100 to stably retain the plate 9 on the movable element 100.
• the fixing layer 13 is defined by a double-sided adhesive ring 14 already provided on the inner surface 11 of the plate 9.
• the ring 14 is placed at the hole 102 of the movable element 100 and the central hole 12 of the plate 9, and is therefore crossed by the aforementioned pin 6.
• the fixing layer 13 can be defined by several distinct double-sided adhesive elements, or by a layer of glue applied to the inner surface 11 of the plate 9 during installation.
• the assembly 1 may further comprise stabilisation means 30 of the plate 9.
• the plate 9 is provided with holes 31, preferably at least two, opposite each other.
• the stabilisation means 30 comprise screws 32, equal in number to the holes 31 of the plate 9. In use, each screw 32 is inserted in a respective hole 9 and in the movable element 100, so as to stabilise the position of the plate 9.
