Description
2116 STEERING WHEEL LOCK The invention relates to mechanisms for locking
the steering wheel of motor vehicles, basically designed to obtain efficient protection against theft, and having the feature that the ignition key simultaneously locks the steering wheel, whereas when contact is broken the steering wheel is released so that it can be manipulated and remains freely rotating so that the vehicle cannot be driven and consequently cannot be removed, the invention being of great interest to users thereof owing to the simplicity of operation, since the ignition key is also used for locking and unlocking, with complete reliability since, in the improbable event of breakage or damage, the steering wheel will always remain locked to the steering column and the vehicle can be driven. the invention being designed with some simple damageproof mechanisms.
The existing technique employed in the various anti-theft mechanisms and devices in use, is mainly designed to provide some short-circuit micro-switches in hidden places, so that the ignition key (or through breaking of cables) does not supply current for starting, other devices existing in which the stee-ring wheel is dismantled and is removed by the user to prevent driving, but in many cases these means are inefficient since thieves.can easily find them.
The improvements according to the present registration eliminate all the difficulties and disadvantages mentioned in the preceding paragraph, since they are designed so that the ignitLon key, in addition to its characteristic function, mechanically locks and unlocks the steering wheel, since the bulb of the ignition-key lock carries an eccentric lever which moves some mechanisms in axial form so that a cross-member acts as a means for locking or unlocking the steering wheel, and is disposed in some recesses made for the purpose in some sleeves which lock or unlock the steering wheel.
For clearer understanding of the general features set out hereinbefore, there are some accompanying drawings in which we show, graphically represented, an embodiment of the improvements introduced in the mechanisms for locking the steering wheel of motor vehicles according to the invention, it being pointed out that in view of the mainly informative function of the drawings in question, the Figures drawn therein should be examined in the widest sense and without any limitative character.
The Figures shown in the accompanying drawings illustrate the following, as explained hereinafter:
Fig. 1. Diametrical section in elevation through the assembly of mechanisms constituting the improvements, being assembled and with the lever secured to the shaft of the ignition-key bulb and the steering wheel being connected and engaged, the inner crossmember being in its lowest position, so that the ends are received in some radial recesses formed in the inner sleeve secured to the steering column.
Fig. 2. The same view in section as in Fig. 1 but when the starting switch is disconnected, the eccentric lever being mounted oip the bulb shaft with its end at the highest point, so that the inner cross-member moves upwards and disengages the inner sleeve secured to the steering column, the cross-member being disposed in the radial grooves in the upper plug and the steering wheel being freely rotatable.
Fig. 3. Diametrical section perpendicular to the assembly in Figs. 1 and 2, the eccentric lever on the bulb shaft being situated between the flanges of a component movable around the steering column and in the form of reel, provided with two ascending bars which secure the locking crossmember, which is in the lowest position as per Fig. 1, thus making contact and locking 4 the steering wheel.
Fig. 4. Top plan view of the mechanisms and the top closing plug, showing the locking cross-member with its ends received in some recesses formed radially in the outer body of the mechanisms, the recess beingprolonged downwardly into the inner sleeve secured to the steering column to obtain engagement, and prolonged upwardly in to other recesses in the plug for disengaging the steering wheel.
Fig. 5. Perspective view of the top closing i plug, formed with some orifices at both sides for the horn switch and comprising a prismatic central body enabling it to be dismantled, and comprising a threaded collar projecting downwardly beyond the radial recesses on both sides so as to receive the locking crossmember.
Fig. 6. Perspective view of the locking crossmember comprising a central body formed with an orifice for the horn conductors and bearing some arms projecting at two opposite points and having orifices at their ends so as to be mounted and secured in some ascending rods forming part of the component movable by the eccentric lever joined to the shaft of the switch.
Fig. 7. Perspective view of the internal sleeve formed axially with a conical grooved orifice for coupling the steering column and securing it by means of a nut and washer, radial recesses being formed at - 5 two diametrically opposite points for securing the cross-member.
Fig. 8. Perspective of the component movable by the eccentric lever and in the form of a reel having two parallel spaced-apart flanges and formed with a through axial orifice for the steering column and with sufficient clearance, the top flange bearing and integral with some ascending rods which have a stepped end bearing the locking crossmember, which is secured by nuts.
Still with reference to the accompanying drawings, we point out that in the various Figures shown therein, there are numerical reference numbers relating to the descriptions hereinafter of its characteristics and operation, thus facilitating'immediate location thereof, (1) being the steering column of the vehicle which is disposed inside the sleeve (2), which contains a component in the form of a reel (3) hav i ng a top f 1 ange (4) and a bottom flange (5) and a central cylindrical body (6) inside which the steering column (1) moves with clearance, the sleeve (2) having an integrally formed sleeve (7) which projects at one side and holds the bulb (8) for the starting switch of the vehicle, whose shaft projects into the interior and is secured to the eccentric lever (9) for mechanically actuating the mechanisms by means of which the steering wheel (10) is locked or unlocked.
The eccentric lever (9) is disposed between the - 6 top flange (4) and'the bottom flange (5) of the reel (3) for axially moving it upwards and downwards, the top flange having some vertical parallel rods (11) situated at two diametrically opposite points, the rods being disposed inside some through orifices formed-in the top block (12) which constitutes the holder for the steering wheel (10), the top end projecting and formed with steps (13) which receive the cross-member (14) formed with lateral orifices (15), into which the ends of the rods (11) are introduced, and are secured via their threaded end (16) and via tightening nuts (17), extending inside radial ducts (18) formed at two diametrically opposite points in the top block (12).
The steering column (1) has its top conical grooved end (19) coupled to the inner block (20) and is firmly secured by its threaded end (21) via a washer (22) and nut (23), the inner block (10) constituting a prolongation of the steering column (1) in its turn, the steering wheel (10) being engaged with the steering column (1) when the switch is actuated, the eccentric lever (9) being disposed at the bottom as shown in Figs. 1 and 3, so that the cross-member (14) is inserted inside the radial recesses (24) formed in the inner block (20), and its ends likewise are inserted in the radial ducts (18) in the top block (12). bearing the steering wheel (10) so that the steering wheel is 'P secured to the steering column.
In order to release the steering wheel (10) so that it can rotate freely, the ignition key (25) is actuated, moving the eccentric lever (9) into the highest position as shown in Fig. 2, thus stopping the vehicle engine, in which case the cross-member (14) will move up out of engagement with the radial recesses (24) of the inner block (20) secured to the steering wheel (10), and is inserted inside recesses (26) formed radially in the descending collar (27) of the top plug (28), which has a thread (29) for mounting on the topblock (12), the plug (28) covering the radial ducts (18), and at the top bearing a prismatic projection (30) so that it can be dismantled by a suitable tool for inspection or repair.
The inner block (20) has one or more blind orifices (31) receiving a spring and ball (32), and at a point in its rotation is opposite another orifice formed in the top block (12) for alignment in the appropriate position for locking or unlocking the steering wheel (10), thus helping the user to find this position, and some through orifices (33) can be formed at one or more places in the top plug (28) for the cables which actuate the horn, together with a central orifice (34) in the crossmember (14) for the same purpose, the cross-member being introduced through the central orifice of the steering column until the circuit is made. An opposing spring (35) is disposed between the - 8 bottom of the inner block (20) and the bottom surface of the cross- member (14) and tends to push the crossmember upwards in order to engage in the recesses (26) in the upper plug (28), thus forcing the reel-like component (3) to occupy the highest possible position, its bottom flange (5) provided with the pad (36) remaining flat against the.eccentric lever (9), avoiding the screw threads, so that the bottom flange (5) can rotate freely.
Considering that this is a full description of all and each of the parts constituting the improvements introduced into mechanisms for locking the steering wheel of motor vehicles to which we have referred, it is only necessary to note the possibility that the various parts can be manufactured in a variety of materials, sizes and shapes, and other constructional variations can be made as found useful in practice, always provided the same are not capable of altering the essential points of the present filed patent of invention.
