Description
SPECIFICATION
Improvements in or relating to apparatus for
restraining relative movement of two components
This invention relates to apparatus for restraining relative movement of two components.
In the motor industry it is known to provide antitheft devices for immobilising motor vehicles. One type of such a device is a cylinder lock adapted to be located adjacent a steering column of a vehicle and adapted to restrain turning of a steering wheel of the steering column. The lock is operated to release the steering wheel by inserting and turning therein a key. In most cases, it is necessary to turn the key through only a small angle to release the steering wheel.
A disadvantage of such a device is that the lock can be operated by skillful manipulation of a serrated blade inserted in an aperture of the lock intended to receive the key and, since it is only necessary to turn the blade through a small angle when inserted in the lock, the lock can be operated in a period of a few seconds.
A further disadvantage of such a device, is that it is not possible to observe that the device is in operation and therefore does not deter breaking into a vehicle in an attempt to steal the vehicle.
According to the present invention there is provided apparatus for restraining relative movement of two components comprising:
a cylinder lock having a cylinder rotatably mounted in a housing the housing being carried by one of said components and
means adapted to be moved into engagement with the other of said components on rotation of the cylinder in the housing to restrain relative movement of the two components in a predetermined direction
wherein the said means is adapted to be moved from a position permitting said relative movement to a position restraining said relative movement when the cylinder is rotated through a plurality of revolutions in the housing.
The said means may include a lost motion device so that the relative movement is restrained only when the cylinder is rotated through a predetermined number of revolutions in the housing.
The said means may comprise a first screw threaded member rotatable on a longitudinal axis of the thread thereof on rotation of the cylinder, a second screw threaded member in engagement with the first screw threaded member and adapted to move along the said axis on rotation of the first screw threaded member and a plunger adapted to be urged by the second screw threaded member into engagement with the other of said components.
The plunger may be resiliently urged away from the first screw threaded member by resilient means.
The resilient means may comprise a helical spring.
Preferably, the two components are adapted to be pivotally connected one to another. The said other of said components comprises an elongate cylindrical member having a plurality of grooves spaced longitudinally of the member, each groove extending circumferentially of the member.
The housing and cylinder may be provided with complimentary abutment and detent members adapted to engage one another to restrain rotation of the cylinder in the housing, the abutment member being adapted to be moved to disengage the detent member to permit rotation of the cylinder in the housing. The abutment member may have a plurality of complementary detent members. Preferably a plurality of abutment members are provided, each abutment member having a plurality of complementary detent members.
Preferably each of said components is provided with a housing adapted to receive one of two components of a motor vehicle. Preferably one of the said components of a motor vehicle is a hand brake and the other of said components of the motor vehicle is a gear lever.
Following is a description, by way of example only with reference to the accompanying drawings, of one method of carrying the invention into effect.

apparatus shown in Figures 8 to 14, and
Figure 15 is an end view of the key shown in Figure
14.
Referring now to Figures 1 to 3, there is shown a device 10 for connecting together a gear lever 11 and a hand brake 12 of a motor vehicle. The gear lever 11 comprises a stem 13 and a knob 14 located at an upper end portion of the stem 13. The hand brake 12 comprises an elongate portion 15 having a handle 16 at an end portion thereof and a button 1 6a for releasing the hand brake from an operative position.
The device 10 comprises a metal rod 17 an end portion of which has secured thereto an end portion of a sleeve 18 which expands through afrusto- conicai portion 18a to an enlarged portion 18b having a longitudinal recess 19. The metal rod 17 has an intermediate grooved portion 20 comprising a plurality of axially spaced grooves 21, each groove extending circumferentially of the rod 17. The device 10 also comprises a tubular shield 23 for containing at least a portion of the gear lever 11, the shield 23 having a rectangular cross section and having a pair of parallel lugs 24,25 extending outwardly of one wall 26 thereof, the wall 26 having a rectangular cut-out portion 27. The lugs 24,25 are journalled on a shaft 28 extending axially from one end of a cylindrical housing 29.The shaft has secured thereto so as to extend radially therefrom a platform 30, the platform extending into the shield 23 when the shaft 28 is turned relative to the lugs 24,25 so that the platform 30 is pivoted into the cutout portion 27. The cylindrical housing 29 is provided with an aperture 31 adapted to receive axially therethrough the rod 17 and is also provided with a cylinder lock 32 for securing the cylinder housing 29 to the rod 17 in a manner to be described hereinafter.
In operation, the gear lever 11 is moved to a position to select a high forward gear and the hand brake
12 is moved to an operative position. The cylindrical housing 29 then is rotated relative to the shield 23 so that the platform 30 is pivoted out of the shield. The shield then is lowered axially over the gear lever 11 so that the gear lever is located therein and the cyli
nder housing 29 is rotated in a reverse direction so that the platform 30 is pivoted into the shield 23 adjacent the stem 13 of the gear lever 11. The rod 17 then is inserted forwardly of the motor vehicle and
axially into the aperture 31 of the cylindrical housing
29. The rod 17 then is moved rearwardly of the vehicle so that the sleeve 18 is moved axially over
the handle 16 of the hand brake 12 thereby covering
the handle 16 and the button 16a.The length of the
grooved portion 20 of the rod 17 is selected such that
when the sleeve 18 covers the handle 16, the cylindr
ical housing 29 is located adjacent the grooved por
tion 20 of the rod 17. The cylinder lock 32 then is
operated to secure the cylindrical housing 29 and the
rod 17 relative one to another and thereby prevent
relative movement of the gear lever 11 and the hand
brake 13. The cylinder lock 32 may subsequently be operated to release the rod 17 from the cylindrical housing 29 so that the shield 23 may be withdrawn from the gear lever 11 and the sleeve 18 may be removed from the hand brake 12.
In some motor vehicles, the gear lever may be located beside the hand brake instead of forwardly thereof. The apparatus illustrated in Figures 1 to 3 may be used with such a vehicle except that the rod 17' (see Figure 4) is curved in the shape of a 'U' instead of being rectilinear.
Referring nowto Figures 5 to 7, there is shown apparatus which is similar to but modified from that shown in Figures 1 to 3 except in that the modified apparatus includes a shield 33 which is provided with a long vertical notch 34 in a wall thereof instead of the rectangular cut-out portion 27 in the corresponding wall of the shield 23 of the apparatus shown in
Figures 1 to 3 and a short vertical notch 35 in an opposite wall thereof. Furthermore, the shield 33 is not provided with a platform corresponding to the platform 30 and the lugs 36,37 thereof corresponding to the lugs24, 25 of the shield 23 arejournalled on a cylindrical housing 38 having an aperture 39 for receiving the rod 17 so that the aperture 39 is located between the lugs 36,37 and is adjacent the notches 34 and 35.
In operation, afterthe gear lever 11 has been moved to a position to select a high forward gear and the hand brake 12 has been moved to an operative position, the shield 33 is lowered axially over the gear lever 11 so that the gear lever 11 is located therein. The rod 17 is inserted through the aperture 39 and the notches 35 and 34 and thereby extends through the shield 33. The rod 17 then is moved rearwardly of the vehicle so that the sleeve 18 is moved axially over the handle 16 of the hand brake 12 thereby covering the handle 16 and the button 16a. The cylinder lock 32 then is operated to secure the cylindrical housing 29 and the rod 17 relative one to another.
Referring now to Figures 8 to 15, there is shown apparatus 40 for locking the cylindrical housing 29 and the rod 17 relative one to another. The cylindrical housing 29 is provided with a longitudinal bore 41 having stepped portions 41 a, 41 b and 41 c of different diameters, the portion 41 a having the smallest diameter and opening radially into the aperture 39, the portion 41 c having the largest diameter and the portion 41 b being located between the portions 41 a and 41c. The portion 41a is defined by an inner circumferential wall which is circular in cross section, the intermediate portion 41 b is defined by an
inner circumferential wall which is rectangular in cross section and the portion 41 c is defined by an
inner circumferential wall which is circular in cross
section. The inner wall defining the portion 41 c of the bore 41 is provided with inwardly directed projections 42 arranged in pairs, the pairs being spaced
from one another longitudinally of the portion 41 c
and the projections 42 of each pair being spaced
from one another circumferentially of the portion
41 c and each pair extending opposite a surface of
the portion 41 c and an adjacent pair or adjacent
pairs.
The portion 41 c of the bore 41 has located therein
a cylinder lock 43 comprising a cylindrical barrel 44
having a plurality of tumblers 45 extending radially
outwardly thereof, the tumblers 45 being spaced from one another axially of the barrel 44 and each tumbler extending radially of the barrel 44 in a direction opposite to the or each adjacenttumbler. The barrel 44 is provided with a central longitudinal bore 46 adapted to receive the shank 47 of a key 48 having a knurled head 49 of circular cross section. If an attempt is made to rotate the barrel 44 on a longitudinal axis thereof, rotation is restrained due to the tumblers 45 abutting the projections 42.However, insertion of the shank 47 of the key 48 effects movement of the tumblers 45 radially inwardly of the barrel 44 a distance greater than the radial dimension of each of the projections 42 whereby the barrel 44 may be rotated on the longitudinal axis inside the portion 41 c of the bore 41.
The barrel 44 has extending from an end thereof nearest the intermediate portion 41 b of the bore 41, a stub shaft 50 of rectangular cross section, which extends into the intermediate portion 41 b. The stub shaft 50 has located thereon an elongate member 51 having a circular cross section and an external thread extending longitudinally thereof. The threaded member 51 has a recess 52 of rectangular cross section extending inwardly of one end thereof and a recess 53 of circular cross section extending inwardly of an opposite end thereof. The stub shaft 50 is located in the recess 52. The threaded member 51 has threaded thereon a sleeve 54 of rectangular cross section, the sleeve having a bore of circular cross section which is internally threaded and which engages the external thread of the threaded member 51.
The portion 41 a of the bore 41 has received therein a plunger 55 having an elongate cylindrical portion 55a which is circular in cross section and has a bore 55b. One end of the plunger 55 is blocked by a wall 55c having a spherical outer surface 55d and an inner annular surface 55e. The plunger 55 has a circumferential flange 55f at the end thereof remote from the wall 55c, the flange having a rectangular outer circumference. The outer circumference of the flange 55f corresponds with the inner circumference of the portion 41 b of the bore 41 and the outer circumference of the elongate cylindrical portion 55a of the plunger 55 corresponds with the inner circumference of the portion 41 a of the bore 41.
The recess 53 of the threaded member 51 has received therein one end of a helical spring 56 the opposite end of which is located in the bore 55b of the plunger 55. The tension of the spring 56 is such that the threaded member 51 is urged axially on the stub shaft 50 so as to be retained thereon and the spring 56 engages the annular surface 55e of the plunger 55 and urges the plunger axially so that the flange 55f abuts the step between the portions 41a and 41 b of the bore 41 in which position the spherical outer surface 55d of the plunger 55 projects into the aperture 39.
In this position, the plunger 55 is resiliently biassed so that when the rod 17 is inserted through the aperture 39, the plunger 55 yields but snaps into each groove 21 as the grooves sequentially are located in the aperture 39.
When the shank 47 of the key 48 is inserted into the bore 46 of the barrel 44 and the key is turned, the barrel 44 is rotated on a longitudinal axis of the cylindrical housing 29. The threaded member 51 is rotated on the same axis due to the cross section of the stub shaft 50 and the recess 52 being rectangular. The sleeve 54 is prevented from rotating on the same axis due to the cross section of the sleeve 54 and the portion 41 b of the bore 41 being rectangular. In consequence, as the threaded member 51 rotates on the said axis, the sleeve 54 being in threaded engagement with the threaded member 51 moves axially of the threaded member 51.
On turning the barrel 44 through a plurality of revolutions, the sleeve 54 engages the flange 55f of the plunger 55 and thereby restrains the plunger from moving inwardly of the cylindrical housing 29 against the bias of the spring 56. If the rod 17 is located so that the spherical outer surface 55d is located in a groove 21 of the rod 17 and the plunger 55 is in engagement with the sleeve 54, the rod 17 cannot be removed from the aperture 39 because the plunger 55 will not yield to axial motion of the rod 17. In this manner, the cylindrical housing 29 and the rod 17 are secured together. However, the rod 17 is released from the plunger 55 when the barrel 44 is rotated in a reverse direction by the key 48 thereby withdrawing the sleeve 54 from the flange 55f.
It will be appreciated that when the gear lever 11 and the hand brake 12 are secured together by the rod 17 and the cylindrical housing 29, the hand brake 12 cannot be operated because the the relative button 1 6a is covered by the sleeve 18. Similarly, the gear lever 11 cannot be moved rearwardly to select a low gear because the frusto-conical portion 1 8a of the sleeve 18 cannot be moved rearwardly of the handle 16 of the gear lever. Also, the shield 23 or 33 cannot be removed from the gear lever 11 because the sleeve 18 is firmly located on the handle 16 of the hand brake 12 and, as added protection, platform 30 is positioned inside the aperture of shield (Figure 1) and rod 17 inside the aperture of shield 33 (Figure 5 alternative construction).
It will also be appreciated that in operation the device in accordance with the present invention is a motor vehicle anti-theft deterrent because the device can be seen in an operative condition through windows of the vehicle. Furthermore, since it is necessary to rotate the barrel 44 through a plurality of revolutions and to ensure that the tumblers 45 are withdrawn radially of the barrel 44 four times in every revolution to avoid the projections 42, the anti-theft deterrent effect is increased because of the increased difficulty and time necessary to turn the barrel 44 in the cylindrical housing 29 to release the rod 17 in the cylindrical housing 29.
