Abstract
Description
- The present invention relates to an electromechanical safety actuator, which may be used in particular, but not exclusively, in the manufacture of an electrically-operated lock and, in general, in systems for controlling access to an environment.
- Document EP-A-0 077 254 shows an electromechanical safety actuator including :
- a support structure ;
- an assembly of parts mounted in the said structure and including a first electric actuator provided to drive a control member connected thereto along a working stroke, moving it in a first sense along the said direction from a rest position to a working position, and in the opposite sense to return it to the rest position;
- resilient biasing means, and a releasable locking device, able to assume a normal locking condition, and an emergency release condition in which it allows the control member to move a distance at least equal to the aforesaid working stroke of the control member along the said direction, in the opposite sense to the said first sense, under the action of the said biasing means.
- The electromechanical safety actuator of the present invention includes :
- a support structure;
- an assembly of moving parts mounted in the said structure with the ability to move along a predetermined direction and including a (first) electrical actuator provided to drive a control member connected thereto along a working stroke, moving it in a first sense along the said direction from a rest position to a working position, and in the opposite sense to return it to the rest position;
- there being associated with the said assembly
- resilient biasing means, and
- a releasable locking device, able to assume:
- a normal locking condition in which it holds the said assembly in a normal, predetermined working position in relation to the structure, against the action of the said biasing means, and
- an emergency release condition in which it allows the said assembly and associated control member to move a distance at least equal to the aforesaid working stroke of the control member along the said direction, in the opposite sense to the said first sense, under the action of the said biasing means.
- The invention also relates to an electric lock according to claim 16 and a system for controlling access through an aperture according to claim 17.
- Further characteristics and advantages of the invention will become clear from the following detailed description, provided purely by way of non-limitative example, with reference to the appended drawings, in which:
- Figures 1 to 3 are sectional views of an electrically-operated lock including an electromechanical safety actuator according to the invention;
- Figure 4 is a partially sectioned view of an electrically-operated lock according to the invention; and
- Figure 5 is a block diagram of an access-control system which includes an electromechanical safety actuator according to the invention.
- In Figures 1 to 4, an electrically-operated lock according to the invention is generally indicated 10. It includes a
support casing 1 constituted (for example) by a metal container shaped like a small rectangular tank. - An electromechanical safety actuator, generally indicated 20, is mounted in the
casing 1 to control the position of twotranslatable control members end 2a of thecontrol member 2 is fixed amember 4 carrying a plurality ofparallel bolts 5 which extend through corresponding apertures in an end wall of thecasing 1. - The
electromechanical actuator 20 comprises anassembly 21 which includes aslide 22 with anelectric motor 23 securely fixed thereto. In the embodiment illustrated, this motor includes arotor 24 threadably engaged by a threadedshaft 25 the ends of which are securely fixed to thecontrol members - Two transverse abutment stops 28 and 29 are fixed inside the
casing 1, on opposite sides in relation to the direction of translation of the assembly formed by thecontrol members shaft 25.Respective studs motor 23, are fixed to these abutment stops (see in particular Figure 3). Twohelical springs studs slide 22. - A toggle mechanism, generally indicated 34, is associated with the end of the
slide 22 opposite to thesprings rods rod 35 is pivoted at 38 on thesupport casing 1. At the end towards themotor 23, therod 36 has aslot 36a through which apivot pin 39 fixed to theslide 22 extends with clearance. - A
wire spring 40 is disposed around thepivotal connection 38 and urges therod 35 to rotate clockwise, towards the upper wall of thecasing 1. - An oscillating
member 41 is pivoted at 42 on thesupport casing 1 and has atoothed portion 43 at one end. At the top, themember 41 has acurved projection 44 from which extends downwardly asection 45 provided to cooperate like a cam with thecentral pivot pin 37 of thetoggle mechanism 34. - The
toothed portion 43 meshes with asprocket wheel 46 which has a small diameter and is fixed for rotation with agear 47 which meshes with a sprocket fixed to the shaft of a miniatureelectric motor 49 fixed to thesupport casing 1. - The
motor 49 is provided to drive the oscillatingmember 41 from the position shown in Figures 1 and 2 to the position shown in Figure 3. - In the position of Figures 1 and 2, the
member 41 is positioned so that itscam section 45 allows thecentral pivot pin 37 of thetoggle mechanism 34 to lie above a line betweenpivotal connections central pivot pin 37 bears against thecam section 45 of themember 41 and holds theslide 22 in the position shown, in which thesprings motor 23 shown in Figures 1 and 2 correspond to the normal working position. In this condition, energisation of theelectric motor 23 causes a translation of the threadedshaft 25 and thecontrol members motor 23 it is possible to move thebolts 5 from a retracted or rest position (Figure 1) to the extended or working position of Figure 2, and vice versa. - A
rod 50, fixed to theslide 22, carries twomicroswitches respective heads member 55 fixed to the threadedshaft 25. Themicroswitches member 55 to act as travel-limit sensors for cutting power to themotor 24 when thebolts 5 have reached their extended position and their retracted position respectively. Themember 55 has anend portion 55a which is slidably engaged in a rectilinear slot of a fixedwall 55b. Thetoggle mechanism 34, the oscillatingmember 41, theelectric motor 49 and the associatedgears 46 to 48 form together a releasable locking device, able normally to hold theassembly 21 locked in the working position of Figures 1 and 2. - The function of this releasable locking device will now be explained in greater detail.
- Conveniently, the oscillating
member 41 has a further, manual control device such as that generally indicated 60 in Figures 1 and 2. In the embodiment illustrated, this device includes alocking cylinder 61 supported by the cover 1' of the casing 1 (see Figure 4). Rotation of this cylinder, controlled by a key, not shown, is able to rotate a lever 62 (Figures 1 and 2) carrying apin 63 which bears against the oscillatingmember 41, urging it to move from the condition shown in Figures 1 and 2 to the condition shown in Figure 3. - The operation and the purpose of the
manual release device 60 will be described in more detail later. - As shown in Figure 4, the
control member 2 can cooperate with a deviator 70, known per se, arranged in thecasing 1 to control the movement of two locking rods, a lower 71 and an upper 72, along a direction perpendicular to that along which thebolts 5 move, so as to engage/ disengage these rods with or fromrespective locking elements 73, 74 which are fixed, respectively, to the floor and to the wall in which the door carrying thelock 10 is mounted. - Outside the
casing 1 of the electrically-operated lock, thecontrol member 3 extends into asimilar deviator device 80 which, in dependence on the movement of the control member, moves twofurther locking rods locking elements - With reference to Figures 1 to 3, two
further microswitches casing 1 for providing respective electrical signals when the oscillatingmember 41 and thetoggle mechanism 34 are in the respective positions shown in Figures 1 and 2. - The electrically-operated
lock 10 described above conveniently forms part of a system for controlling access through an aperture closed by a door or the like, with which the electrically-operated lock is associated. The general structure of such an access control system is schematically illustrated in Figure 5. - This system basically includes an
electronic control unit 90 with a plurality of inputs, generally indicated 91, connected to themicroswitches outputs electric motors - The
electronic unit 90 is normally supplied through apower supply 94, the input of which is connected to the electrical mains. - Conveniently, the
electronic unit 90 may be supplied by abuffer accumulator 95 with which is associated, in known manner, arecharging device 96 connected to the mains. - The supply inputs of the
electronic unit 90 are also conveniently connected to asocket 97 which may be connected to a commercially available,portable battery 98, for example of the type used in portable radios. Conveniently, thesocket 97 is positioned near the door with which the electrically-operatedlock 10 is associated, outside the environment to which the door controls access. - The
electronic unit 90 is preset to activate/de-activate the electrically-operatedlock 10 in dependence on coded control signals transmitted to it by means of acontrol device 100. This latter may be constituted by a coded electronic key or by a fixed keyboard provided for entering a predetermined command code, or it may be constituted by a remote-control device able to transmit coded command signals to theunit 90, for example by ultrasound or by infra-red radiation or by radio frequency transmission. - In the following description it is assumed that the
device 100 is a remote-control device. It is clear, however, that the points which follow apply equally to adevice 100 constituted by the other means described above. - The
device 100 may conveniently have twocontrol pushbuttons lock 10 and the second enabling thelock 10 to be released in the case of an emergency, as described hereafter. - The access-control system which includes the electrically-operated
lock 10 operates as follows. - In normal conditions, the assembly of moving parts 21 (
slide 22, electric motor 23) of the electrically- operated lock is held in the normal working position of Figures 1 and 2 by the releasable locking device which includes thetoggle mechanism 34, the oscillatingmember 41 and theelectric motor 49. - In these conditions, pressing the
button 101 of the remote-control device 100 sends a coded signal to theelectronic control unit 90. This compares the -signal received with a previously memorised identification code and, in the case of positive identification, activates theelectric motor 23 so as to move thebolts 5 and the (possible) lockingrods - Should there be a momentary mains power failure, the
electronic control unit 90 is supplied by thebuffer accumulator 95. - If, after having commanded the release of the lock (that is the retraction of the
bolts 5 and therods button 101 of the remote-control device 100, this operation is not carried out, for example because of a failure of theelectric motor 23, the user can in any case control the release of the electrically-operatedlock 10 by pressing the emergency-release button 102 of the remote-control device. As a result of this action, the remote-control device sends a coded signal to theelectronic unit 90 which, on recognising the code, activates theminiature motor 49 of the electrically-operated lock, causing the oscillatingmember 41 to move from the position of Figures 1 and 2 to the position of Figure 3. As a result of this movement by themember 41, itscam section 45 causes thecentral pivot pin 37 of thetoggle mechanism 34 to move downwardly, below the straight line joining the pivotal connection points 38, 39 at the ends of this mechanism. Consequently, the movable assembly 21 (slide 22,electric motor 23, threadedshaft 25 andcontrol members 2 and 3) is made to translate by thesprings bolts 5 into thesupport structure 1 and disengages the (possible) lockingrods - In one particularly unfortunate situation, it is possible that the
button 102 is pressed but the emergency release operation described above does not take place, for example because mains electricity has failed and thebuffer accumulator 95 is low, meaning that no power is supplying the electronic control unit. In this case, the user may conveniently fit a portable, commercially available battery, such as that indicated 98 in Figure 5, to thesocket 97 thereby enabling this battery to supply theunit 90. At this point, renewed pressure on thebutton 102 will send the coded emergency release signal to theunit 90 which, once it has positively recognised the code, will activate theminiature motor 49, supplying it with current delivered by thebattery 98 fitted to thesocket 97. - The access-control system described above may also include devices able to recognise an identification code transmitted via a telephone line. In this case, the system must naturally be connected or connectable to a telephone line.
- The control unit of the system will also release the electrically-operated lock in an emergency upon recognising the said code transmitted to it via a telephone line.
- The
manual control device 61, on the other hand, enables the electrically-operated lock to be released in an emergency from inside the environment, which may be accessed through the door. In the case of a failure or malfunction of the system of Figure 5, it is possible to move the oscillatingmember 41 from the position of Figuresl and 2 to the position of Figure 3 by using a key -in thecylinder lock 61 to rotate thelever 62 anti-clockwise and thereby release the electrically-operated lock as a result of the assembly of movingparts 21 being moved by thesprings - In order to prevent
lever 62 from being rotated by means of thelock 61 while the electromechanical lock actuator is in the inoperative condition shown in Figure 1, a locking arrangement (not shown) can be conveniently associated with saidlever 62; this locking arrangement can include (for instance) a blocking member carried by thecontrol member 3 and capable of preventing the oscillation of saidlever 62 whenmember 3 is in the position of Figure 1. - After an emergency release operation (and naturally after having resolved the problem which necessitated the emergency operation), the electrically-operated lock may be put back into service, that is into its normal operating condition, in the following manner.
- A signal commanding closure of the electrically-operated lock is transmitted to the
electronic unit 90 by pressing thebutton 101 of the remote-control device 100. On posivitely recognising the code, theelectronic unit 90 first starts theminiature motor 49 so as to return the oscillatingmember 41 to the position shown in Figures 1 and 2, in which itscam section 45 does not obstruct the passage of thecentral pin 37 of thetoggle mechanism 34 beyond the straight line connecting the pivotal connection points 38 and 39. When themember 41 has reached the position of Figure 1, themicroswitch 65 transmits a corresponding signal informing theelectronic unit 90. At this point the said unit activates theelectric motor 23 so that, together with theslide 22, it translates along the threadedshaft 25, towards the left according to Figure 3. As a result of this translation, thetoggle mechanism 34 is extended and, as soon as thecentral pin 37 is aligned with thepivotal points wire spring 40 causes thecentral pin 37 to pass beyond the line joining thesepivotal points central pin 37 bears against thecam section 45 of the oscillatingmember 41. - The
microswitch 66 sends a signal informing theelectronic unit 90 that thetoggle mechanism 34, as well as theslide 22 and theelectric motor 23, have been returned to their normal working position (Figure 1). Activated by theslide 22, themicroswitch 56 sends a signal to the electronic unit.90 which, on reception of this signal, is set to enable theminiature motor 49 to be supplied with inverse current whenever a new emergency release operation is required. - Naturally, the principle of the invention remaining unchanged, the embodiments and manufacturing details may be varied widely from the above description and illustrations, provided purely by way of non-limitative example, without departing from the scope of the present invention as detailed in the appended claims.
