Definitions

  • the present invention relates to a security device for handles.
  • the invention is mostly used in handles for "shutters and frames" (such as for example doors, windows, etc.) in order to prevent the opening of the shutter and frame by unauthorized persons.
  • a house is normally provided with further access points, such as for example windows, French doors overlooking on balconies, terraces or gardens.
  • Such shutters and frames are often the weak point for the security of a house. Typically, they comprise walls made with thicknesses and/or materials (for example glass, wood, etc.) that can make the shutter and frame easily vulnerable to tampering (for example perforations).
  • a technique by which thieves often can open such shutters and frames consists in making a through-hole of little size on a wall of the shutter and frame. The hole can be made silently and in a short time. From the through-hole it is thus possible to introduce a suitably bent bar inside the house, whereby it is possible to move the handle of the shutter and frame (for example by turning it) causing the opening thereof.
  • handles provided with a lock operable by means of a key adapted to lock the rotation of the handle and to make the opening of the shutter and frame by the thieves an extremely complex operation or, anyway, a long and/or noisy operation (for example, the thieves may be forced to make a passage with large dimensions on the shutter and frame from which they may sneak into the house), are known.
  • Such security systems if on one hand allow avoiding the opening of the handle by strangers, on the other hand they oblige the house owner and inhabitants to use the keys each time they should open the window, if it has been previously locked.
  • Such a situation in addition to be awkward, could also be dangerous in case of emergency during which it could be needed to quickly open the windows and/or doors of the house, for example for an evacuation or to ventilate the environment in case of gas leak.
  • the presence of keys to open the various locks of the handles may extend the opening operation of the shutters and frames during an emergency.
  • DE 26 25 779 A1 discloses a handle for windows provided with a safety device to lock the rotation of the handle comprising a button that can be pressed towards the wall of the window by counteracting the elastic force of a spring. The button protruding from the cover, is accessible to the user for pushing it and allowing the unlocking of the handle.
  • handles provided with a locking and unlocking mechanism of the handle rotation and actuated by means of a button placed at the throat of the handle, have been made. In this way, the user can push the button with the thumb and unlock the rotation of the handle by grabbing the handle.
  • a further need relative to handle security systems is to avoid the opening of the windows by children at home.
  • a young child realizing that there is an unlocking button on the handle, could easily try to push it and succeed in opening the window.
  • a solution may be to make the button of the handle so that it could be pushed with high force. In this way, a young child cannot unlock the handle since not able to apply a high force on the button, but the unlocking of the handle may turn out being an awkward operation for an adult that will need to apply a certain force on the button to be able to open the shutters and frames.
  • Object of the present invention is to provide a security device for shutters and frames, of simple construction and able to lock the handle of a shutter and frame in a safer and more reliable way with respect to security devices of known art.
  • Further object of the present invention is to provide a security device for shutters and frames and a method for locking and unlocking a handle able to make the unlocking of the handle a simple and quick operation for an adult and, at the same time, difficult for a child.
  • the security device is adapted to be installed on shutters and frames of the type that comprise an activating lever rotatable around a rotation axis between at least one closed position and at least one open position of the shutter and frame.
  • the activating lever comprises a handle, i.e. a member intended to be grasped by the user, and a respective operating shaft.
  • the operating shaft can have quadrangular section in order to activate a clamping mechanism for shutters and frames of known type by transmitting its rotary motion, herein not further specified.
  • the handle is provided with a "neck" (i.e. an ending portion of the handle) having a seat with section equal to that of the operating shaft, for example and preferably with a quadrangular section, and is adapted to axially accommodate an ending portion of such an operating shaft. In this way, by rotating the handle the rotation is transmitted to the operating shaft to activate the clamping mechanism of the shutter and frame.
  • the activating lever is normally coupled to the shutter and frame by means of a supporting element named "rosette” (i.e. a washer).
  • the washer for example typically made of plastic or metallic material, is fixed to a wall of the shutter and frame (for example by means of screws), close to the clamping mechanism.
  • the washer is provided with a hub for supporting and placing the activating lever correctly with respect to the clamping mechanism of the shutter and frame, thus allowing the activating lever to reach different open and closed positions of the shutter and frame.
  • some activating levers are provided with a screw, or similar threaded element, adapted to transversely engage on the neck of the handle until reaching and locking the ending portion of the operating shaft.
  • Other activating levers provide for the handle neck and the washer hub being provided with quick hooking means so that to constrain the neck of the handle to the hub by preventing the axial movement of the handle.
  • the washer is covered by a covering element used to hide the fixing screws of the washer that may look unsightly.
  • the covering element can be cup-shaped, i.e. having a concave shape, to cover at least even partially the edge of the washer.
  • the inner part of the covering element i.e. the part interfacing with the washer, can further be provided with ribs to constrain the edge of the covering element with the edge of the washer.
  • the covering element is configured to cover at least the entirety of a face of the washer. More preferably, the covering element comprises a covering portion extending on a plane substantially perpendicular to the rotation axis of the handle. Said covering portion is configured to substantially cover the entire outer surface of the washer.
  • the covering element is usually provided with a through-hole so that a coupling portion of the activating lever can pass.
  • the coupling portion is a substantially intermediate portion of the activating lever, in particular it can be defined as the portion of the activating lever at the coupling between the operating shaft and the handle, substantially placed close to the hub of the washer.
  • the coupling portion of the activating lever can comprise, or be constituted by, at least one ending portion of the operating shaft and/or at least one ending portion of the handle (for example a portion of the neck of the handle) and/or at least one portion of the hub of the washer.
  • the covering element is movable between a distal position and a proximal position with respect to the washer.
  • the covering element can substantially translate along the rotation axis of the activating lever between two positions: a proximal position, i.e. at a short distance from the washer (for example in contact with the washer), and a distal position, i.e. at a longer distance from the washer.
  • the security device also comprises countering elastic means to hold the covering element in distal position.
  • the elastic means can comprise for example springs arranged between the washer and the covering element.
  • the elastic means can be made integrally to the washer, for example they can comprise flexible protrusions jutting from the washer towards the covering element.
  • the security device further comprises shape-interfering locking means between the covering element and the coupling portion of the activating lever.
  • Such locking means are shaped to obtain shape interference between the coupling portion of the activating lever and the covering element, in order to prevent the rotation of the activating lever when the covering element is in distal position.
  • the locking means are shaped so that when the covering element is led to proximal position, the covering element doesn't interfere with the coupling portion of the activating lever and thus the locking means allow the rotation of the activating lever.
  • the shape-interfering locking means are preferably arranged between the through-hole of the covering element and the coupling portion of the activating lever.
  • the locking means can comprise a portion of the covering element (preferably at the through-hole) having a shape complementary to a corresponding part of the coupling portion of the activating lever.
  • the shape of the through-hole can advantageously be made so that to obtain at least one fin jutting towards the inside of the through-hole.
  • the locking means further comprise at least one seat made on the coupling portion of the activating lever, adapted to accommodate the respective fin when the covering element is in the distal position.
  • one or more seats can be made on the outer surface of the hub of the washer so that to prevent the rotation of the hub and, consequently, of the activating lever thanks to the shape interference between at least one fin of the covering element and at least one seat of the hub.
  • the coupling portion of the activating lever comprises a groove to allow the rotation of the activating lever when the covering element is in the proximal position.
  • the groove reduces the section of the coupling portion interfacing with the covering element so that the covering element doesn't interfere with the coupling portion when the covering element is in the proximal position.
  • the shape-interfering locking means are arranged so that the interference between the coupling portion and the covering element is obtained when the activating lever is in the closed position.
  • the user starting from a closed position of the activating lever, wherein the covering element is held in distal position by elastic means, in order to rotate the activating lever from the closed position to an open position, the user must press the covering element to lead it to the proximal position. Once the covering element has been led to proximal position, the user can rotate the activating lever until reaching an open position.
  • the locking means can be shaped so that the covering element can move back to the distal position (by the thrust of the elastic means) when the activating lever is in the open position. In this case, once the covering element reached the distal position, it interferes with the coupling portion of the activating lever preventing the rotation even when the activating lever reached the open position. In this embodiment, the covering element must be pressed and held in proximal position also to lead the activating lever from an open position to a closed position.
  • the locking means can be shaped so that the covering element is still hold in the proximal position when the activating lever reaches an open position.
  • the shape-interfering locking means are arranged so that the rotation of the activating lever is only prevented when the activating lever has reached a closed position.
  • the covering element When the activating lever reached an open position, the covering element remains in the proximal position, thus, starting from an open position, the user can rotate the activating lever with one hand only until the activating lever reaches the closed position. During the rotation of the activating lever from the open position towards the closed position, the covering element doesn't interfere with the activating lever thanks to the groove made on the coupling portion of the activating lever.
  • the groove is shaped so to axially counter the thrust of the elastic means by holding the covering element in proximal position with no need by the user to hold it pressed.
  • the covering element pushed by the elastic means reaches the distal position and, by interfering with the coupling portion, prevents a subsequent rotation of the activating lever.
  • the elastic means for example springs and/or flexible protrusions
  • the two or more pressure points are configured to allow the movement of the covering element from the distal position to the proximal position only if pressed together.
  • the rotation axis of the activating lever is arranged between the aforementioned two or more pressure points of the covering element.
  • the elastic means for example springs and/or flexible protrusions
  • the elastic means are arranged between the washer and the covering element symmetrically with respect to the rotation axis of the activating lever, preferably in at least two diametrically opposite points.
  • Such a configuration turns out being effective to prevent the opening of the shutter and frame by unauthorized persons, for example by children that would hardly be able to press the covering element on two distant points with one hand only and, at the same time, rotate the handle with the other hand by holding the covering element pressed. Instead, such an operation turns out being easy for an adult. Also since an unlocking button or lever (such as for example in the security devices of the known art) is not visible, the security device according to the present invention turns out being less avoidable by thieves and esthetically less invasive with respect to the known security devices discussed above.
  • Another object of the present invention is a method for locking and unlocking a handle by means of a safety device comprising an activating lever rotatable between at least one open position and at least one closed position, a washer, and a movable covering element adapted to cover at least partially said washer, said activating lever comprising a handle coupled with an operating shaft of a clamping mechanism for shutters and frames.
  • the method comprises the steps of:
  • the covering element can be moved closer and away with respect to the washer, between a proximal position and a distal position.
  • the locking and unlocking of the handle happen by axially translating the covering element between the distal position and the proximal position.
  • the step of b) locking the handle is carried out through shape-interfering locking means between the covering element and a coupling portion of the activating lever.
  • step b) is carried out through countering elastic means arranged between the covering element and the washer, and step c) is carried out by pressing the covering element.
  • the unlocking of the handle can only take place if the covering element is pressed to lead it to the proximal position.
  • the user must use two hands, thus making such an operation less avoidable by unauthorized persons.
  • step c) is carried out by pressing at least two points of the covering element, preferably at least two diametrically opposite points.
  • the present invention it is possible to make an inexpensive security device of simple construction, for shutters and frames.
  • the ease of construction further allows to adapt the device according to the present invention to any type of shutter and frame without alteration of the appearance of the handle and/or of the shutter and frame and ensuring an adequate security against intrusions and unauthorized openings of the shutter and frame.
