Definitions

  • the present invention relates to a cylinder, in particular an electronic cylinder, for driving mechanism.
  • cylinders typically of standardized dimensions, which are coupled to driving mechanisms, typically frame locks or other mechanisms such as switches for the control of automatic devices (e.g. motors for opening/closing gates or doors).
  • driving mechanisms typically frame locks or other mechanisms such as switches for the control of automatic devices (e.g. motors for opening/closing gates or doors).
  • a cylinder for driving mechanisms can typically comprise a main body (also called stator) on which there is rotatably fixed a cam (commonly named tongue) having a protruding portion.
  • the cam which typically serves to drive the driving mechanism to which the cylinder is applied, is mechanically couplable to a rotating body (commonly known as plug), housed in the main body, for being able to drive the driving mechanism after a rotation of the rotating body.
  • cylinders for driving mechanisms called electric or electronic, i.e. cylinders containing, in addition to or in substitution of mechanical blocking mechanisms mechanically driveable by conventional keys or the like, at least one blocking mechanism, typically comprising at least one electric power supplier and one actuator (e.g. an electromagnet or an electric motor), which is usually operated on the basis of the result of an electronic identification.
  • the electronic identification involves the reading, by an access control system, of digital data relating to access rights contained in an electronic key (such as an electronic card, a smartphone or other wireless device, or a device physically connectable to the access control system through a suitable entrance).
  • EP2706172 and EP2706173 describe known electronic cylinder for driving mechanisms.
  • the Applicant has found that the known electronic cylinders for driving mechanisms have some drawbacks and/or can be improved in some aspects.
  • Object of the present invention is therefore to provide an electronic cylinder for driving mechanisms which does not require complicated operations and/or procedures for the assembly and/or the installation and/or the maintenance, such as the replacement of the electric batteries
  • the invention relates to a cylinder for driving mechanisms according to claim 1.
  • the combination of the aforesaid features in particular the presence of the electric power supplier (entirely) housed inside the handling body and the presence of the access opening to the supplier realized on a face of the handling body facing away from the cam and distal from the latter and/or on a surface of the handling body having (substantially) longitudinal development, i.e.
  • the lateral surface of the handling body realizes an electronic cylinder for driving mechanisms which does not require complex maintenance operations and/or procedures, since the aforementioned access to the electric power supplier allows to replace the supplier itself (if exhausted and/or in general no longer functioning) without requiring the disassembly and the reassembly of the handling body from the rest of the cylinder and without the need for specifically dedicated tools (such as for example in the aforementioned EP2706172 and EP2706173 ).
  • reversibly referred to a process/operation it is meant a process/operation which does not destroy or damage a device (or parts thereof) on which the process/operation is performed, i.e. that the process/operation can be performed not destructively on the device so that it can be repeated at will and such that its effect can be cancelled without consequences for the device itself.
  • said electric power supplier comprises one or more accumulators, for example electric batteries or capacitors.
  • the handling body comprises a removable cover for closing said opening and protecting the electric power supplier.
  • said electric power supplier is housed in an end portion of said handling body distal from said cam. In this way the insertion and/or the extraction of the electric power supplier is facilitated.
  • said cylinder comprises a command and control unit mainly, more preferably entirely, housed inside said handling body and electrically connected to said electric power supplier. In this way the electric contacts of the command unit remain confined inside the handling body
  • said electric power supplier occupies a position (longitudinally) farther from said cam with respect to said command and control unit.
  • said command and control unit is programmed and configured to receive as an input a signal (preferably a wireless signal) identifying an access right and for actuating said actuator on the basis of a verification of said signal identifying an access right.
  • a signal preferably a wireless signal
  • said actuator comprises an electric motor electrically connected to said electric power supplier and to said command and control unit.
  • an electromagnet which typically continues to consume current for as long as the thrust element is driven (with a consequent reduction in the life of the accumulator/s)
  • the electric motor can provide for the driving of the electronic cylinder with a lower overall consumption of electric power.
  • said actuator (preferably said motor) is at least partially (more preferably mainly) housed in said handling body.
  • said structure of the cylinder is simplified since it does not need for electric contacts between the handling body and the rest of the cylinder for connecting the motor to the electric power supplier and/or to the command and control unit (such as for example in EP2706172 and EP2706173 ).
  • the present feature allows to free space inside the rotating body, thus loosening the design constraints.
  • first element inside of a second element it is meant that more than 50% (preferably more than 60% or 70%) of the overall volume of the first element is enclosed in the second element.
  • Said actuator is a linear actuator acting along said longitudinal direction. In this way it is possible to adapt the electric driving of the cylinder to the logic and to the components of a purely mechanical driving cylinder (as described below).
  • Said actuator comprises a thrust element (a rod) having a main development direction along said axis of rotation, wherein said actuator is structured to rectilinearly displace said thrust element from an at-rest position distal from the cam to a thrust position proximal to the cam.
  • a thrust element a rod
  • said actuator is structured to rectilinearly displace said thrust element from an at-rest position distal from the cam to a thrust position proximal to the cam.
  • Said thrust element is mechanically connected to said coupling element in such a way that a displacement of said thrust element from said at-rest position to said thrust position gives to said coupling element a thrust force towards said cam or towards said rotating body.
  • the driving of the thrust element allows the coupling between the cam and the rotating body (if the rotating body is correctly angularly aligned with the cam).
  • said cylinder comprises a first elastic element (e.g. a spring) operatively interposed between said coupling element and said thrust element and structured to oppose an (increasing) elastic reaction to a (increasing) displacement of said thrust element from said at-rest position to said thrust position.
  • a first elastic element e.g. a spring
  • the first elastic element keeps in thrust the coupling element towards the cam (or towards the rotating body), allowing the coupling between the cam and the rotating body, if there is a correct angular alignment between the two aforesaid elements.
  • the first elastic element keeps in thrust the coupling element against an abutment wall of the cam (or of the rotating body) avoiding at the same time an effort by the motor (which instead would occur in an alternative embodiment of the invention wherein the thrust element is rigidly connected to the coupling element).
  • the coupling element can assume the coupling position (in which, for example, suitable protuberances of the coupling element engage corresponding seats made in the cam and in the rotating body) and thus achieve the coupling between the cam and the rotating body.
  • the first elastic element tends to bring the thrust element back to the at-rest position.
  • said cylinder is structured and programmed to maintain said thrust element in said thrust position for a time interval (preferably definable at will), more preferably without electric power consumption by the actuator.
  • a time interval preferably definable at will
  • the thrust on the coupling element is maintained, and therefore the possibility of driving the driving mechanism to which the cylinder is applied, for the time necessary and established at will by the user, preferably without power consumption and therefore without effects on the life of the power supplier.
  • said cylinder is structured and programmed so that, after said time interval, the motor ceases to give to said thrust element any force (including bind reaction forces) having longitudinal direction directed towards said cam. In this way, terminated the time interval, the motor stops acting on the thrust element, which is free to return to the at-rest position without further action by the motor and therefore without further electric power consumption (the motor consumes electric power only in the displacement of the thrust element from the at-rest position to the thrust position).
  • said cylinder comprises a second elastic element (e.g. a spring) operatively interposed between said main body and said coupling element and structured to oppose an (increasing) elastic reaction to a (increasing) displacement of said coupling element from said decoupling position to said coupling position.
  • a second elastic element e.g. a spring
  • the second elastic element tends to bring the coupling element back to the decoupling position, preventing the driving of the driving mechanism by rotation of the rotating body.
  • said first and/or second elastic element are compression springs, more preferably equal to each other, and arranged along said longitudinal direction at opposite sides of said coupling element. In this way the elastic reactions of the first and of the second elastic elements are suitably oriented.
  • said first and/or second elastic element have a respective degree of preloading in a closing configuration of the cylinder in which said thrust element is in the at-rest position (and said coupling element is in the decoupling position). In this way it is ensured that the elastic elements correctly act in all the configurations of the cylinder even in the face of manufacturing tolerances.
  • a degree of preloading of said second elastic element is greater than a degree of preloading of said first elastic element. In this way it is reduced the risk that the coupling element mistakenly remains in the coupling position even in absence of further external forces acting on the coupling element.
  • said cylinder comprises a further rotating body rotatably housed in a further cavity of the main body realized at the opposite side of said cam with respect to said cavity, and having a respective axis of rotation coinciding with said axis of rotation of the rotating body.
  • said further rotating body is firmly and rigidly coupled to said cam to rotate rigidly with said cam about said axis of rotation. In this way the rotation of the further rotating body always causes a driving of the driving mechanisms.
  • said rotating body and said further rotating body comprise a respective cavity having (substantially) longitudinal development.
  • said cylinder comprises a further handling body at longitudinally opposite side with respect to said handling body and structured to rotate said cam about said axis of rotation at least when said coupling element is in said coupling position. In this way it is possible to drive the driving mechanisms even at opposite side with respect to the handling body.
  • said handling body is (firmly) fixed to said rotating body to rotate rigidly with said rotating body about said axis of rotation.
  • said further handling body is (firmly) fixed to said further rotating body to rotate rigidly with said further rotating body about said axis of rotation.
  • said handling body is (firmly) fixed to said further rotating body to rotate rigidly with said further rotating body about said axis of rotation.
  • said further handling body is (firmly) fixed to said rotating body to rotate rigidly with said rotating body about said axis of rotation.
  • the cylinder according to the last two embodiments can be advantageously mounted so that the handling body can be gripped respectively from the outside (in the first embodiment) or from the inside (in the second embodiment) of an environment whose access is controlled by a frame (or in general another access barrier device) on which a driving mechanism comprising the cylinder is mounted.
  • brackets refer preferably to the aforesaid second embodiment while the text outside parenthesis refers preferably to the aforesaid first embodiment.
  • said cavity of said rotating body comprises a first mouth placed at one end of said rotating body (or of said further rotating body) distal from said cam, said first mouth being facing towards (and preferably engaged by) said actuator.
  • said cavity of said rotating body comprises a second mouth placed at one end of said rotating body (or of said further rotating body) proximal to said cam, said second mouth being facing towards, and engaged by, said coupling element. In this way, a connection channel between the actuator and the coupling element is made inside the rotating body (or the further rotating body).
  • said thrust element in said thrust position develops at least partially inside said cavity of said rotating body (or of said further rotating body).
  • said first elastic element is housed in said cavity of said rotating body (or of said further rotating body) and comprises a first end in contact with said coupling element and a second end structured to receive a thrust force from said thrust element. In this way it is possible to transfer to the coupling element the thrust force imparted by the thrust element, adapting at the same time the cylinder to the typical operating logic of a purely mechanical driving cylinder, since there are maintained the coupling element and its logic of coupling the rotating body to the cam.
  • said cavity of said further rotating body comprises a mouth placed at one end of said further rotating body (or of said rotating body) proximal to said cam, said mouth being facing towards, and engaged by, said coupling element (at least when in the coupling position).
  • said second elastic element is housed in said cavity of said further rotating body (or of said rotating body). In this way the second elastic element is suitably placed to impart an elastic reaction to said coupling element to bring the coupling element from the coupling position to the decoupling position, once all the further external forces acting on the coupling element (e.g. the thrust force of the thrust element) have been cancelled.
  • said cylinder comprises a contact body interposed between said thrust element and said first elastic element.
  • the present invention includes any type of electronic cylinder for driving mechanisms, for example electronic whole cylinder with a single actuator (wherein the cylinder comprises on one side an electronic driving and on the other a manual driving, as shown below in the first embodiment), electronic whole cylinder with a double actuator (not shown, wherein the cylinder comprises an electronic driving on both sides), electronic half cylinder (not shown, wherein the cylinder comprises an electronic driving on one side and no driving on the other side), or hybrid cylinder (wherein the cylinder comprises on one side an electronic driving and on the other a mechanical key driving, as shown in the second embodiment), and of any shape, such as for example the European cylinder shape exemplarily shown below, or, not shown, oval, round, etc.

  • the first 16 and the second elastic element 18 have a respective degree of preloading wherein the degree of preloading of the second elastic element 18 is greater than the degree of preloading of the first elastic element 16.
  • Exemplarily the greater degree of preloading of the second elastic element 18 is achieved housing the second elastic element 18 in a cavity (which corresponds to the cavity 22 for the first embodiment and to the cavity 21 for the second embodiment) having a longitudinal dimension about 0.05 mm smaller than a longitudinal dimension of the cavity (which corresponds to the cavity 21 for the first embodiment and to the cavity 22 for the second embodiment) wherein the first elastic element 16 is housed.
  • a rotation of the handling body 9 (first embodiment) or of the further handling body 23 (second embodiment) is free, i.e. without a corresponding rotation of the cam 5, since the rotating body 4, integral with respectively the handling body 9 or the further handling body 23 is decoupled from the cam 5.
  • the command and control unit 13 In presence of a signal identifying an access right, this signal is received and processed by the command and control unit 13 in order to verify a correct access authorization. In case of positive result, the command and control unit 13 commands the actuator 7, for example the motor 14, so that the thrust element 15 is moved from the at-rest position to the thrust position. The thrust element 15, through the contact body 30 and the first elastic element 16, generates a thrust force on the coupling element 6 towards the cam 5.
  • Each of the cam 5 and the rotating body 4 has a pair of seats with longitudinal development, diametrically opposed with respect to the axis of rotation 100 and shaped to be engaged by the radial prominences of the coupling element 6.
  • the first elastic element 16 keeps the coupling element 6 in thrust against an abutment wall 17 of the cam 5 (first embodiment), or an abutment wall 32 of the rotating body 4 (second embodiment), at the same time avoiding an effort by the motor 14 (which would instead occur in case of a rigid connection between the thrust element 15 and the coupling element 6).
  • the coupling element 6 is free to reach the coupling position (e.g. it moves towards the cam in the first embodiment or towards the rotating body in the second embodiment) thus achieving the coupling between the cam 5 and the rotating body 4 (opening configuration shown in figures 3 and 6 ).
  • a rotation of the handling body 9 in the first embodiment, or of the further handling body 23 in the second embodiment determines a rotation of the cam 5 and therefore an opening of the lock.
  • the cylinder 1 (more preferably the actuator comprising the motor 14) is structured and programmed to keep the thrust element 15 in the thrust position for a time interval definable at will (for example from few seconds to several hours) and without electric power consumption. In this condition, when the cylinder is in the opening configuration the actuator overcomes the elastic reaction force of the second elastic element 18, which remains compressed.
  • the cylinder 1 is preferably structured and programmed so that, terminated the time interval, the motor 14 ceases to impart to the thrust element 15 any force (including bind reaction forces) having longitudinal direction directed towards the cam 5.
  • the first 16 and the second elastic element 18, structured to oppose a respective increasing elastic reaction to an increasing displacement respectively of the thrust element 15 from the at-rest position to the thrust position and of the coupling element 6 from the uncoupling position to the coupling position mutually cooperate to bring the thrust element 15 and the coupling element 6 respectively back to the at-rest and to the decoupling positions, bring the cylinder back to the closing configuration.
