Definitions

• the present invention relates to an electric lock.
• the component is generally a card that can contain a microprocessor or be provided with a magnetic strip: in any case its purpose is to store a code associated with the lock to be actuated.
• the door protected with this type of lock, has in general, on the inner side, a first handle associated with a respective spring latch, which always allows the door to be opened from the inside.
• a second handle On the outer side, there is a second handle, which is also associated with a respective spring latch, and a reader that is capable of engaging with the codified component in the user's possession, in order to receive its authorization and enable this second handle and thus the movement of the spring latch.
• Doors provided with electronic locks thus have, generally, on the inner side, a knob, which is capable of disabling the second handle which is outside the door, so that it is possible to prevent access to the room by the service staff, or by anyone who has an accredited codified key.
• the devices that make it possible to disable the second, outer handle of the door are generally complex and are constituted by a plurality of components, with consequent higher probability of malfunctioning that, moreover, involves high maintenance costs, because of the need to disassemble and reassemble the various parts, which are often small.
• the aim of the present invention is to solve the above-mentioned drawbacks, by providing an electric lock that is constituted by a reduced number of components.
• an object of the invention is to provide an electric lock that is highly versatile.
• Another object of the present invention is to provide an electric lock which is low-cost, easily and practically implemented and safe in application.
• an electric lock that is provided on the inner side with a first handle 2 and with a knob 3, and on the outer side with a second handle and with an assembly for reading a codified key, where between said second handle and said spring latch means of mutual decoupling are interposed, characterized in that it comprises a main body provided with a seat for the rotatable accommodation of a transverse shank of said knob, said decoupling means comprising a contoured disk that is integral with said knob, an idle toothed wheel provided with a lower profiled plate that constitutes a cam, and a switch facing the edge of said plate, said contoured disk comprising a toothing that is distributed over a predefined angle and is removably coupled with respective recesses in said toothed wheel, the rotation of said knob determining the rotation of said disk, with consequent entrainment of said toothed wheel, limited to the predefined angle of said toothing, and orientation of said plate corresponding to its interference with the
• Figure 1 is a perspective view of the electric lock according to the invention.
• Figure 2 is a perspective view of the electric lock, according to the invention, without a covering element
• Figure 3 is a perspective view from the left of the means of mutual decoupling of the electric lock, according to the invention.
• Figure 4 is a perspective view from the right of the means of mutual decoupling of the electric lock, according to the invention.
• Figure 5 is a front elevation view of the means of mutual decoupling of the electric lock, according to the invention.
• the reference numeral 1 generally designates an electric lock provided, on the inner side, with a first handle 2 and with a knob 3.
• the lock On the outer side, the lock is provided with a second handle and with an assembly for reading a codified key.
• Such key is generally a card or pass on which, according to different methods, a code associated with the lock to be actuated, is stored.
• the card can be provided with a microprocessor, or a bar code, or be provided with a magnetic strip.
• the user by swiping or inserting the codified key in an adapted seat, or simply by bringing it in the proximity of the reading assembly, enables the second handle, and as a consequence the spring latch, thus gaining access to the room.
• the electric lock 1 comprises a main body 5 provided with a seat 6 for the rotatable accommodation of a transverse shank 7 of the knob 3.
• the decoupling means 4 comprise a contoured disk 8 which is integral with the knob 3, an idle toothed wheel 9 that is provided with a lower profiled plate 10 that constitutes a cam, and a switch 11 facing the edge 12 of the plate 10.
• the contoured disk 8 comprises a toothing 13 that is distributed over a predefined angle and is coupled removably with respective recesses 14 of the toothed wheel 9.
• the rotation of the knob 3 by the user who is inside the room thus causes the rotation of the disk 8 with consequent entrainment of the toothed wheel 9, limited to the predefined angle of the toothing 13, and orientation of the plate 10 that corresponds to its interference with the button 15 of the switch 11.
• the user in order to actuate the switch 11 and prevent access to the room by the service staff, or by anyone who has an accredited codified key, can rotate the knob 3 in both directions, obtaining in any case the necessary coupling between the disk 8 and the toothed wheel 9, and orienting the plate 10 so that it can interfere with the button 15 of the switch 11.
• the contoured disk 8 can be provided with at least two teeth 16 that are arranged over a predefined angle and are coupled removably with respective recesses 14 of the toothed wheel 9.
• the lock 1 can comprise a dynamometric locking device 17 to prevent the accidental rotation of the toothed wheel 9.
• Such device thus prevents an unforeseen rotation, for example owing to the action of the force of gravity on the toothed wheel 9 or on a component connected thereto, such as the knob 3, from causing the actuation of the switch 11, and the consequent inability of the user to access the room.
• the locking device 17 can comprise a pin 18 that is elastically forced on the recesses 14 of the toothed wheel 9 by way of a spring 19 that has an axial action.
• the elastic action of the spring 19 thus causes the locking of the wheel 9 at applied moments of an intensity lower than a preset value.
• the switch 11 is controlled by a mechanical actuator that decouples the second handle from the spring latch.
• the plate 10 has a shape that is preferably selected from an ellipsoid, a shape with an eccentric circumference, and the like.
• the mechanical actuator which decouples the second handle from the spring latch, can be controlled by the assembly for reading a codified key.
• the switch 11 disables the reading assembly.
• the reading assembly cannot disable the mechanical actuator, and thus access to the room by the service staff, or by anyone who has an accredited codified key, is in this manner prevented.
• the lock 1 can comprise a signaling device, that can emit a light beam of differing preset color depending on whether the switch is engaged or otherwise.
• the user once inside the room, when he or she needs to prevent access thereto by other people, rotates the knob 3, in one direction or the other, until the signaling device emits a light beam of a different and preset color.
• the electric lock 1 is constituted by a reduced number of components.
• the electric lock 1, according to the invention is highly versatile.
• the lock 1 can be mounted without any modification or adaptation being necessary.
• the knob 3 can rotate in both directions, thus ensuring in any case the necessary coupling between the disk 8 and the toothed wheel 9, and orienting the plate 10 so that it can interfere with the button 15 of the switch 11.
• the materials employed may be any according to requirements and to the state of the art.
