Abstract
Description
- The present invention relates to a device for controlling an electric vehicle door lock.
- More specifically, the present invention relates to a control device of the type comprising a supporting frame fitted directly to a vehicle door; a pushbutton switch; and means for manually operating the pushbutton switch.
- To operate the pushbutton switches controlling electric locks, various solutions are known, which normally comprise a push element fitted to the supporting frame and which is moved manually by the user into a forward switching position to activate the pushbutton switch; and one or more elastic reaction elements separate from the push element and interposed between the push element and the frame to keep the push element in the rest position.
- Though used, known electric lock operating devices have several drawbacks, foremost of which are the large number of components involved, complex manufacture and assembly, and, consequently, high cost.
- Moreover, some known solutions are only used on a very limited scale, on account of the push element only being movable into the forward switching position by acting on a given point of the device - an inconvenience which is rarely acceptable, especially by more demanding users.
- It is an object of the present invention to provide a device for controlling an electric vehicle door lock, designed to eliminate the aforementioned drawbacks, and which, in particular, is straightforward and cheap to produce and provides for a high degree of reliability and efficiency.
- According to the present invention, there is provided a device for controlling an electric lock of a vehicle door, the device comprising a respective supporting frame fitted directly to a vehicle door, a pushbutton switch fitted to the frame, and manual operating means for manually operating the pushbutton switch; characterized in that said manual operating means comprise a single elongated body at least partially deformable elastically and which acts directly on said pushbutton switch; relatively-movable means being provided to fit said elongated body to said frame.
- A non-limiting embodiment of the invention will be described by way of example with reference to the accompanying drawings, in which:
- Figure 1 shows a side view of a preferred embodiment of the control device according to the present invention, as fitted to a partially illustrated vehicle door;
- Figure 2 shows a view, with parts removed for clarity, in the direction of arrow A in Figure 1;
- Figure 3 shows a section, with parts removed for clarity, along line III-III in Figure 1.

-
Number 1 in Figures 1 and 3 indicates as a whole a vehicle door, the body 2 of which comprises anopening 3 through which extends adevice 4 for operating an electric lock (not shown) ofdoor 1. -
Device 4 comprises a respectiveelongated frame 5 having a respectivelongitudinal axis 6 and in turn comprising an elongated annular plate 7. Plate 7 comprises twolongitudinal portions 8 facing each other and parallel toaxis 6; and twotransverse portions 9 facing each other, extending perpendicular toaxis 6, and defining, together withlongitudinal portions 8, arectangular opening 10 extending along axis 6 (Figures 2 and 3). -
Frame 5 also comprises- abracket 12 for supporting a knownpushbutton switch 13, which is oriented with anaxis 14 coincident with an activating direction ofswitch 13, perpendicular toaxis 6, and intersectingaxis 6 at a point P substantially equidistant fromtransverse portions 9 and fromlongitudinal portions 8. More specifically,bracket 12 defines a click-in seat 15 forswitch 13, which is clicked into seat 15 through alateral opening 16. Inside seat 15,switch 13 is maintained in a fixed position by a pair ofpins 18, which extend inside seat 15 perpendicularly toaxes hole 19 inswitch 13. - With reference to Figures 1 and 2,
frame 5 also comprises, for eachtransverse portion 9, a pair of facingelastic walls 21 integral withrespective portion 9 and extending parallel to and on opposite sides of aplane containing axes -
Walls 21 in each pair define arespective seat 22 for arespective end portion 23 of anelongated body 24 made of plastic material and also comprising an elongatedintermediate portion 25, which extends atopening 10 and in a raised position with respect to plate 7, and which, in use, cooperates directly with, to operate or activate, switch 13. - Each
portion 23 ofbody 24 is connected to the respective pair ofwalls 21 by a respective click-in connectingassembly 26 comprising, for eachrespective wall 21, aslot 27 parallel toaxis 14 and facing theslot 27 in theother wall 21 in the same pair. Theslots 27 formed inwalls 21 in the same pair are engaged byrespective pins 28, which are integral withrespective portion 23, extend coaxially with acommon axis 29 perpendicular toaxes respective slots 27 in sliding manner in directions parallel toaxis 14 and in rotary manner aboutcommon axis 29 to define, together with the respective walls, a hinge with a hinge axis movable crosswise to itself. Eachpin 28 is defined axially by a respectiveinclined front surface 30, which, when fittingbody 24 toframe 5, cooperates in sliding manner with a respective inclined lead-in surface internally definingrespective wall 21, to enablepin 28 to click into and remain insideslot 27. - With reference to Figures 1 and 2, each
portion 23 carries a respective integralelastic blade 32, which projects towardsswitch 13, is positioned facing and parallel toportion 25, and is separated transversely fromportion 25 on the same side asswitch 13. Eachblade 32 has a respectivecylindrical end portion 33 contacting a respective stop surface internally defining one arm of a respective L-shaped bracket 34, the other arm of which is integral with plate 7, and extends perpendicularly to plate 7 on the same side aswalls 21. - As shown in Figures 2 and 3, plate 7 of
frame 5 is covered partly by a hood-type seal 36 comprising anintermediate portion 37 covering the surface of plate 7 facing outwards in use, and a peripheralannular portion 38. More specifically,intermediate portion 37 extends on the opposite side of plate 7 tobody 24, and comprises a pair of opposite elongatedlongitudinal projections 39 and 40 (Figure 3);projection 39 projects inwards ofseal 36 throughopening 10, loosely engages opening 10, and, in use, directly contactsportion 25 ofbody 24; whileprojection 40 projects outwards, and is defined by a cylindrical lateral surface acted on by the user to open the lock (not shown). -
Annular portion 38 ofseal 36 extends between plate 7 and body 2, and is gripped between plate 7 and body 2 by means of anassembly 42 for clickingframe 5 onto body 2 (Figure 3). - As shown particularly in Figure 3,
assembly 42 comprises anelongated anchoring element 43, which is integral with plate 7, extends parallel toaxis 6 throughopening 3 in body 2, and is anchored to body 2; and a click-onappendix 44, which is also integral with plate 7, extends throughopening 3 on the opposite side ofbody 24 to anchoringelement 43, and terminates with a tooth clicked onto body 2. - In actual use, when
projection 40 is pressed, as of the rest condition shown in Figures 1 and 3,seal 36 is deformed to moveprojection 39 gradually towardsportion 25 ofbody 24 through opening 10. As soon asprojection 39contacts portion 25,elastic blades 32 are deformed to enableportions 23 to move with respect torespective walls 21, andportion 25 to activateswitch 13. And as soon as the pressure applied by the user onprojection 40 is released,blades 32 restorebody 24 to the rest position. - As compared with known solutions,
device 4 as described is therefore extremely straightforward to produce and quick to assemble. This is mainly due to switch 13 ofdevice 4 being activated by asingle body 24 made in one piece from plastic material and supporting integral elastic reaction elements, and by slidingbody 24 alongaxis 6 and parallel to plate 7, so thatportions 23 ofbody 24 slide betweenrespective walls 21, and pins 28 click insiderespective slots 27. - Unlike known solutions, the design characteristics of
body 24 and the particular way in whichbody 24 is connected to frame 5 also enableswitch 13 to be activated by pressing any portion ofprojection 40. That is, if pressure is applied by the user at point P,portion 25 ofbody 24 simply translates parallel to itself alongaxis 14, by bothblades 32 being subjected to the same bending moment. Conversely, if pressure is applied on or close to one of hinge axes 29,portion 25 practically only rotates about theother hinge axis 29. In all the other intermediate conditions,portion 25 rotates and translates towardsswitch 13. - Being extremely straightforward in design,
device 4 as described is therefore also highly reliable, which is further enhanced by the particular design ofseal 36 and by permanent sealing of the frame-body connection.
