Abstract
Description
- The present invention relates to an actuating device, particularly for activating the safety lever of a vehicle door lock.
- In most applications of the aforementioned type, the actuating device comprises control means connectable to the safety lever on the lock; an electric motor for powering the control means; and a gear mechanism located between the electric motor and the control means, and comprising a reduction unit and a rack. The control means, normally consisting of a fork element connectable to the safety lever, are connected to the rack, which is normally connected to a guide so as to move between two limit positions wherein the safety lever is respectively locked and released.
- Though widely used, known devices of the type briefly described above present several drawbacks, foremost of which is the relatively poor mechanical efficiency and dynamic performance of the gear mechanism due to the rack being connected in sliding manner to the guide. A sliding connection in fact requires considerable force for activating the moving element and overcoming friction and inertia at the more critical, i.e. breakaway, stage, thus requiring the use of a relatively high-power electric motor, which poses serious design problems for enabling manual operation of the safety lever in the event of failure of the electric motor. In the majority of cases, manual operation is assisted by providing the gear mechanism with systems for disconnecting and so preventing operation of the actuating device when manually operating the safety lever.
- A further drawback of known devices of the aforementioned type is that they are fairly noisy.
- It is an object of the present invention to provide an actuating device, particularly for activating the safety lever of a vehicle door lock, designed to overcome the aforementioned drawbacks, and which, in particular, is cheap and easy to produce, and provides for troublefree manual operation of the safety lever in the event of failure of the actuating device itself.
- According to the present invention, there is provided an actuating device, particularly for activating the safety lever of a vehicle door lock, comprising a control element connectable to the safety lever on the lock; an electric motor for powering said control element; and a gear mechanism located between said electric motor and said control element and housed inside a casing supporting the actuating device adjacent to said lock; characterized by the fact that said gear mechanism comprises a sector gear located between said control element and said electric motor and pivoting on said casing so as to rotate in relation to the same; said sector gear being connected angularly to said electric motor; and said control element being connected in angularly fixed manner to, and rotating together with, said sector gear.
- A non-limiting embodiment of the present invention will be described by way of example with reference to the accompanying drawings, in which:
- Fig.1 shows a side view, with parts removed for clarity, of a preferred embodiment of the actuating device according to the present invention;
- Fig.2 shows a section along line II-II in Fig.1;

Number 1 in Fig.s 1 to 3 indicates an actuating device for activating thesafety lever 2 of a vehicle door lock 3. -
Device 1 is housed inside acasing 4 comprising twoportions screws 7 and the peripheral annular contacting portion of which defines alabyrinth seal 9.Casing 4 is connected to lock 3 in a predetermined position, preferably by means of two screws 10 (only one of which is shown in Fig.1), or, according to a variation not shown, is fitted firmly to lock 3 by means of a snap-on connecting device. - As shown in
Fig.s device 1 comprises acontrol element 11 connectable tosafety lever 2; anelectric motor 13 forpowering element 11; and agear mechanism 14 located betweenmotor 13 andcontrol element 11. - With reference to Fig.1,
mechanism 14 comprises a pinion 15 fitted to the output shaft ofmotor 13, which is housed inside acavity 16 defined byportion 5 ofcasing 4; and an intermediate gear 18 (Fig.s 1 and 3) meshing with pinion 15 and mounted for rotation about acylindrical body 19. As shown in Fig.3,cylindrical body 19 is mounted for rotation in relation tocasing 4 by means of apin 20 force-fitted inside a through hole 21 coaxial withcylindrical body 19, and the opposite ends of which project outwards ofbody 19 and engage, in rotary manner,respective seats 22 formed inportions casing 4. - Again with reference to Fig.3, between
portion 6 ofcasing 4 andintermediate gear 18,cylindrical body 19 presents afurther gear 23 coaxial withpin 20 and secured angularly tointermediate gear 18 via a known butterfly face coupling 24 (not described) enabling predetermined relative rotation ofgear 23 andintermediate gear 18. - As shown in Fig.1,
mechanism 14 also comprises asector gear 25 meshing withgear 23 and secured tocasing 4 so as to rotate in relation to the same about anaxis 26 coincident with the axis of rotation ofcontrol element 11. More specifically (Fig.2),sector gear 25 is connected by anelbow 27 to theintermediate portion 28 of apin 29 parallel topin 20 and also comprising twoend portions 30 and 31;portion 30 engaging in rotary manner aseat 33 formed inportion 6 ofcasing 4; and portion 31 extending outwards ofcasing 4 through ahole 34 engaged loosely by portion 31 and formed in arecess 35 onportion 5 ofcasing 4. - Again with reference to Fig.2, portion 31 is fitted in angularly fixed manner with the
end portion 37 ofcontrol element 11, which is substantially Z-shaped. More specifically, afree end portion 38 of portion 31 presents two diametrically-opposed flat milledportions 39, and engages a seat 40 formed inend portion 37 ofcontrol element 11 and so shaped as to define two flat surfaces interacting with milledportions 39.Control element 11 is also secured axially in relation topin 29 by ascrew 42 extending through ahole 43 formed inend portion 37 ofcontrol element 11 and coaxial with seat 40, and engaging a threadedhole 44 formed inpin 29. - As shown in Fig.2 and particularly Fig.1, in addition to
end portion 37,control element 11 also comprises a fork-shaped lever 45 extending outwards ofcasing 4 and made integral withportion 37 by awall 46 also extending outwards ofcasing 4 and defined, on theside facing casing 4, by a curved surface having its concaveside facing pin 29.Lever 45 extends outwards ofcasing 4 substantially on the opposite side ofintermediate portion 28 ofpin 29 as compared withelbow 27, and presents a substantially V-shaped opening 47 extending substantially perpendicularly topin 29, with its concavity facingsafety lever 2.Lever 2 comprises apin 48 extending through and engaging in sliding manner opening 47, so as to angularlysecure lever 45 to lever 2 of lock 3. - Finally, as shown in Fig.s 1 and 2,
device 1 comprises alimit stop device 49 for limiting rotation ofsector gear 25 and lever 45 to a first and second limit position wherein the safety lever is respectively locked and released, as shown by the dotted and continuous lines respectively in Fig.1. More specifically,limit stop device 49 comprises a cylindrical projection 50 integral withsector gear 25, extending on the opposite side ofsector gear 25 as compared withintermediate gear 18, and cooperating, in use, with substantially semicylindrical walls 51 (Fig.2) integral with an inner surface ofportion 6 ofcasing 4 extending towardssector gear 25. For cushioning the impact between projection 50 andwalls 51, assector gear 25 switches from one to the other of said limit positions, projection 50 is fitted with anelastomeric shock absorber 52. - As shown in Fig.1,
device 1 comprises amicroswitch 53 adjacent tointermediate gear 18 andpin 29, and activated by an appendix 54 (Fig.2) integral withelbow 27, extending on the opposite side ofelbow 27 as compared with projection 50, and cooperating with thecontrol lever 55 ofmicroswitch 53. When activated byappendix 54,microswitch 53 provides for supplying a position signal to a timed control system (not shown) for switching the polarity ofelectric motor 13 and so invertingmotor 13 and, consequently, rotation ofsector gear 25. To prevent external pollutants from contactingmicroswitch 53, theparts facing pin 29 andintermediate gear 18 are protected by twowalls 56 integral withportion 5 ofcasing 4, substantially surroundingpin 29 and partially surroundingintermediate gear 18, and extending belowelbow 27. - As shown in Fig.s 1 and 3,
casing 4 is so formed as to define a firstelectric connector 58 comprisingfirst terminals 59 ofwiring 60 ofmotor 13, and second terminals (not shown) of wiring 60' of a device 61 (Fig.1) for detecting imperfect closure of lock 3. More specifically, wiring 60' comprises a first number of electric cables (not shown) having one end connected to the terminals (not shown) integral withconnector 58, extending outwards ofcasing 4 through an opening 62 (Fig.1) inportion 6, and having the opposite end integral with a firstintermediate connector 63 housed inside a seat 63' inportion 6 ofcasing 4. Wiring 60' also comprises a second number of electric cables having one end connected to a second intermediate connector 63'' connectable in releasable manner to firstintermediate connector 63 integral withcasing 4, and the opposite end connected to detectingdevice 61. - According to the variation shown in Fig.s 4 and 5, detecting
device 61 comprises wiring 64 (shown partially) withoutintermediate connectors 63 and 63'', extending entirely outsidecasing 4, and terminating in aconnector 65 havingterminals 66 and designed to click inside a seat 67 inportion 6 ofcasing 4. Seat 67 is formed next toconnector 58housing terminals 59 ofmotor 13, and is substantially parallel to the longitudinal axis ofconnector 58, so that, when connected,terminals 66 ofdevice 61 are substantially parallel to those ofmotor 13. More specifically (Fig.5),connector 65 ofdevice 61 comprises afirst terminal 69 projecting outwards ofconnector 65; and asecond terminal 70 insideconnector 65 and defining aseat 71 for theend portion 72 of ametal element 73 substantially similar tofirst terminal 69 and fitted firmly toconnector 58 integral withcasing 4. - In actual use, assuming all the electric connections have been made, and
safety lever 2 of lock 3 is set to the release position shown by the continuous line in Fig.1, operation ofelectric motor 13 results in clockwise rotation of pinion 15 fitted to its output shaft, and in rotation ofintermediate gear 18, which, by virtue of being secured angularly, as opposed to fitted, tocylindrical body 19 byface coupling 24, initially rotates idly aboutbody 19 long enough to bringmotor 13 up to substantially normal operating speed. Subsequently,face coupling 24 rendersintermediate gear 18 angularly fixed in relation tocylindrical body 19 and, consequently, integral withgear 23 formed onbody 19 and meshing withsector gear 25, which thus moves from the limit position shown by the continuous line to that shown by the dotted line in Fig.1. For the reasons already stated, rotation ofsector gear 25 results in similar clockwise rotation oflever 45, which movessafety lever 2 into the locked position wherein projection 50 forming part oflimit stop device 49 ofsector gear 25 contactssemicylindrical wall 51 oncasing 4, thus limiting clockwise rotation ofsector gear 25; andappendix 54 integral withelbow 27 cooperates withcontrol lever 55 ofmicroswitch 53, which supplies a position signal to the timed control system (not shown), which in turn provides for inverting in known manner the polarity ofelectric motor 13. A further control signal supplied to the control system by the user provides for activatingmotor 13 in the opposite direction, and for resettingsafety lever 2 to the released position, at which point the original operating conditions, pending further operation ofsafety lever 2, are restored by the control system. - The advantages of actuating
device 1 according to the present invention will be clear from the foregoing description. In particular, it provides for enhanced mechanical efficiency ofgear mechanism 14, thus enabling the use of smaller, low-powerelectric motors 13. - Secondly, it is extremely straightforward in design, and provides for a high degree of reliability. The design of
gear mechanism 14 in particular provides for troublefree manual operation ofsafety lever 2 in the event of failure ofelectric motor 13, by virtue of all the components ofmechanism 14 being connected in rotary manner to the supporting structure, thus greatly reducing friction as compared with sliding components, and enabling the elimination of systems for disconnecting and preventing operation of actuatingdevice 1 when manually operatingsafety lever 2. - Thirdly, the design of
control element 11, in particular the fact that it is formed in two separate parts, provides for safeguarding against external pollutants by eliminating the need for an opening incasing 4 for enabling rotation oflever 45. - Fourthly,
electric connector 58, integral withcasing 4 and fitted with the terminals ofelectric motor 13, microswitch 53 and open-door detecting device 61, enables the above to be connected to the vehicle wiring system (not shown) in one single operation, preferably by means of robots, with no need for skilled labour. - Finally, the reliability of
device 1 is further enhanced bylabyrinth seal 9 formed along the mating edge ofportions casing 4, and bywalls 56 safeguardingmicroswitch 53 from external pollution. - To those skilled in the art it will be clear that changes may be made to actuating
device 1 as described and illustrated herein without, however, departing from the scope of the present invention. For example,sector gear 25 may be replaced by a normal gear; and the angular position oflever 45 may be determined by detectors mounted onpin 29 supportingsector gear 25.
