DESCRIPTION
TITLE OF INVENTION
STEERING LOCK DEVICE
TECHNICAL FIELD [0001]
The present invention is related to steering lock devices; particularly, the invention relates to antitheft steering lock devices for reliably keeping the steering locked even if the cylinder lock is removed in order to improve the antitheft capability.
BACKGROUND ART [0002]
In steering lock devices, because cylinder locks are sometimes removed from steering lock devices in order to steal a vehicle, steering lock devices are already known that have a deadlock mechanism to keep the steering locked and prevent vehicle theft even if the cylinder lock is removed.
[0003]
FIG. 10 is a partial cross-sectional view of a conventional deadlock mechanism installed on this type of conventional steering lock device. As illustrated in the figure, the deadlock mechanism 10 has a recess 13 formed at a position which is on the lateral portion of the body 12 of the steering lock device and faces the rear section of the cylinder lock 11 with each component of the deadlock mechanism mounted in the recess 13; moreover, a cover 14 covers the recess 13.
[0004]
That is, the deadlock mechanism 10 includes the parts of a cam lever 16 which applies a force in the direction of the cylinder lock 11 by a first spring 15 and a catch pin 20 which is able to be inserted into a catch groove 19 of a cam shaft 18 by a second spring 17.
The deadlock mechanism 10 configured above operates as described below.
In Fig. 10, the deadlock mechanism 10 is in a state in which the mechanism has not been operated yet, i.e. a steering shaft is able to be moved between a locked position and an unlocked position upon insertion of a key into the cylinder lock 11.
[0005]
That is, if the key is rotated from the LOCK position to in this case the ACCESSORY position (ACC position), the cam shaft 18, which is coupled with the key cylinder 21 of the cylinder lock 11, is also rotated in one rotational direction causing the lock bolt to move backward and unlocking the steering.
However, if the key rotates from the ACC position to the LOCK position, the cam shaft 18 is rotated in the opposite rotational direction, and the lock bolt moves forward causing the steering to lock.
[0006]
If the cylinder lock 11 is in the lock position without a key inserted and the cylinder lock 11 is removed from the body 12, the catch pin 20 protrudes into the catch groove 19 preventing the rotation of the cam shaft 18 as shown in FIG 11.
In other words, if the cylinder lock 11 is removed, the cam lever 16 moves backward (toward the right side in FIG. 10) in accordance with the backward movement of the cylinder lock 11 and the spring force of the first spring 15, so that the front portion of the cam lever 16 separates from the lower portion of the catch pin 20.
[0007]
In the situation in which an a theft is attempted and the cylinder lock is removed, the catch pin 20 protrudes into the catch groove 19 due to the spring force of the second spring 17 preventing the cam shaft 18 from rotating. Thus, if the cylinder lock 11 is intentionally removed in order to steal the vehicle, the catch pin 20 is able to prevent the cam shaft 18 from being rotated, therefore this configuration provides an effective vehicle antitheft device.
However, if the cylinder lock 11 needs to be repaired or replaced and the cylinder lock is in the ACC position with a key, the cam shaft 18 needs to be disposed in a predetermined position, in this case the ACC position so that the cam shaft 18 will be unable to rotate so that the deadlock mechanism does not become engaged.
[0008]
Furthermore, when installing either a new or repaired cylinder lock into the body 12, the repaired or new cylinder lock 11 pushes and moves the cam lever 16 with respect to the body. As a result of movement of the cam lever 16, the curved front portion of the cam lever 16 pushes and moves the catch pin 20 so as to separate the catch pin 20 from the catch groove 19.
As set forth above, the cam shaft 18 is able to rotate in response to the movement of the key cylinder 21, and enables the steering to switch between locked or unlocked positions.

SUMMARY OF INVENTION [Solution to Problem] [0010]
In a conventional steering lock device as set forth above, installing each component of the deadlock mechanism 10 deep inside the body 12 and far from the mouth is very difficult; in order to be able to install the components, a conventional steering lock device has a recess 13 with an opening formed on the lateral part of the body 12, wherein each component is able to be installed in the recess 13 through the opening to the recess 13 whereafter the opening is covered with a cover 14.
[0011]
However, in the deadlock mechanism 10 if the cover 14 is breached or removed, each component is able to be removed from the recess 13, and therefore, illegal operation becomes possible.
Because of this configuration, when the cylinder lock 11 is removed from the body 12, the catch pin 20 is able to be disengaged from the catch groove 19 which creates the problem that the cam shaft 18 is able to be rotated; and consequently, the steering is able to be illegally unlocked.
Accordingly, a device which provides a recess 13 and a cover 14 which are as small as possible is desired.
[0012]
To solve the above problems, an object of the present invention is to propose a steering lock device which improves the antitheft capabilities of a vehicle.
[Solution to the Problem] [0013]
To achieve the objective set forth above, one embodiment of the invention proposes a steering lock device which includes a cylinder lock, a lock bolt, a deadlock member, a trigger rod, a spring and an attaching member. The cylinder lock has a key cylinder configured so as to be rotatable with the insertion of a key. The lock bolt moves between a locked position in which the lock bolt engages with a steering shaft, and an unlocked position in which the lock bolt does not engage with the steering shaft when the key cylinder is rotated. The deadlock member moves from a disengaged position in which the deadlock member is not engaged with the lock bolt to an engaged position in which the deadlock member is engaged with the lock bolt by means of the spring force and prevents the lock bolt from moving into the unlocked position. The trigger rod has a proximal end portion and a distal end portion, wherein the proximal end portion is disposed so as to be engaged with the cylinder lock which is restricting the position of the trigger rod in a restricted position and the distal end portion is engaged with the deadlock member in such a manner that the deadlock member is in the disengaged position. The spring applies a biasing force on the trigger rod causing the trigger rod to move in the direction of the proximal end portion. The attaching member, which is operatively connected to the trigger rod and the spring, is installed within the body via the mouth of the body, prior to the cylinder lock being installed within the body.
[0014]
Further, a second embodiment of the invention proposes to adapt the first embodiment of the steering lock device such that one of either the attaching member or the trigger rod has an elongated guide hole and the other of either the attaching member or the trigger rod has a projecting guide portion, wherein the elongated guide hole and the projecting guide portion are provided in such a manner that the elongated guide portion is engaged with the projecting guide portion and the elongated guide hole guides the movement of the trigger rod, and in which the spring is arranged parallel to the trigger rod’s direction of movement and between at least a portion of the attaching member and the trigger rod.
[0015]
Further, a third embodiment of the invention proposes to adapt the first or the second embodiment of the steering lock device such that at least a portion of the cylinder lock is inserted through an opening in the attaching member.
[Advantageous Effects of Invention] [0016]
In the first embodiment of the invention, a subassembly which is created by attaching the trigger rod, which is part of the deadlock mechanism, and the spring, which applies a biasing force on the trigger rod, to the attaching member.
This subassembly is then inserted through the mouth of the body and is installed within the body; the cylinder lock is, subsequently, installed through the mouth of the body.
[0017]
This setup allows the trigger rod, which is part of the deadlock mechanism, and the spring to be installed through the mouth of the body deep inside and far from the mouth of the body; consequently, this setup eliminates the necessity of a large recess and/or a large cover in order to mount the components of the deadlock mechanism outside of the body.
Therefore, the steering lock device has improved antitheft capabilities over a conventional steering lock device in which the cover is able to be easily removed, the dead lock mechanism easily disabled, causing the steering to become unlocked.
[0018]
In the second embodiment of the invention, the trigger rod is biased by the spring causing the trigger rod to move in one direction, thereby controlling the position of the projecting guide portion within the elongated guide hole.
Moreover, because the trigger rod is biased by the spring, when the projecting guide portion comes into contact with a portion of the wall of the elongated guide hole of the trigger rod, the portion of the wall exerts an opposing force on the projecting guide portion counteracting the force exerted by the projecting guide portion. This biasing force holds the trigger rod in place so as to operatively attach the trigger rod to the attaching member and forming the subassembly.
[0019]
Further, a third embodiment of the invention is characterized in that the attaching member has an opening through which a portion of the cylinder lock is able to be inserted, in order to install the attaching member within the body prior to installing the cylinder lock within the body.

DESCRIPTION OF EMBODIMENTS [0021]
Embodiments of the present invention are described based on the Figures.
FIG. lisa side view of a steering lock device for a vehicle in accordance with an embodiment of the present invention. In the embodiment illustrated in Fig. 1, ‘31’ is the body, ‘32’ is the cylinder lock, ‘33’ is a mounting member which is attached to the steering column of a vehicle, ‘34’ is a mounting member for an ignition switch, and ‘35’ is a lid for covering the dead lock member. The lid 35 is secured using set bolts 36, with each set bolt having a specific screw thread formed inside the head.
[0022]
FIG. 2 is a cross-sectional view taken along the line A-A shown in FIG. 1. As illustrated in FIG. 2, the cylinder lock 32 is installed within the mouth 31a of the body 31. The key cylinder 37 which is able to be rotated by an inserted key is disposed in the cylinder lock 32.
The key cylinder 37 has a cam mechanism 38 arranged at the rear end portion of the key cylinder 37. The cam mechanism 38 is operatively connected to the key cylinder 37 and integrally rotates with the key cylinder 37.
[0023]
The steering lock device has a lock bolt 39 which is able to move forward or backward in response to the rotation of the cam 38.
As illustrated in FIG. 3, a joint 40 is arranged such that one end of the joint 40 is operatively connected to the cam 38 and the other end of the joint 40 is coupled to the lock bolt 39. A spring 41 for the lock bolt is arranged between the lock bolt 39 and the cam 38.
FIG. 3 is an exploded perspective view of the steering lock device.
[0024]
When a key is inserted into the cylinder lock 32 and is rotated from the ACC position to the LOCK position, the cam 48 also rotates in accordance with the rotation of the key cylinder 37, which causes the lock bolt 39 to move backward in response to the rotation of the cam 38. Thereby, the front portion of the lock bolt 39 retracts from the concaved portion of the steering shaft and unlocks the steering.
Alternatively, when the key is rotated from the ACC position to the LOCK position, the cam 38 also rotates in accordance with the rotation of the key cylinder 37, which causes the lock bolt 39 to move forward from the unlocked position thereof in response to the rotation of the cam 38. Thereby, the front portion of the lock bolt 39 is projected into the concave portion of the steering shaft and locks the steering shaft.
[0025]
Further, the steering lock device has a deadlock mechanism. The deadlock mechanism comprises a deadlock member 50, a first spring 51, a trigger rod 52, a second spring 53 and an attaching member 54, as illustrated in FIGs. 2 and 3.
[0026]
First, as shown in the enlarged portions of the steering lock device in Fig. 4, in the present embodiment the body of the deadlock member 50 is substantially pin-like with the enlarged-diameter portion 50b being formed by a substantially inclined surface 50a. The 8 body 31 of the steering lock device has an insert hole 3Id, a recessed portion 31b and a slide hole 31c for the lock bolt 39, arranged on the lateral side within the body 31. The insert hole 3 Id is disposed between the lower surface of the recessed portion 31b and the slide hole 31c of the lock bolt 39 such that the dead lock member 50 can be inserted into the insert hole 3Id and is able to be moved forward or backward within the insert hole 3Id.
The first spring 51 is arranged between the lid 35 as described above and the enlargeddiameter portion 50b, and the deadlock member 50 is biased toward the lock bolt by the first spring 51.
[0027]
Further, the trigger rod 52 is arranged so as to be engageable with the inclined surface 50a of the deadlock member 50.
That is, the trigger rod 52 has an elongated, plate shape in the present embodiment. The trigger rod 52 is disposed so as to be movable with respect to the attaching member 54 and the trigger rod 52 is laterally arranged within the body. As described below, the front portion of the trigger rod 52 has a distal end portion with an inclined portion 52a facing the inclined surface 50a of the deadlock member 50.
[0028]
Further, a second spring 53 is arranged between the trigger rod 52 and the attaching member 54; the trigger rod 52 is also biased by the second spring 53 toward the mouth 31a of the body 31.
In other words, the rear end portion ( proximal end portion) of the trigger rod 52 experiences an opposing force by a portion 32a of the cylinder lock 32 to the biasing force experienced by the second spring. Thereby, the inclined portion 52a of the front portion (distal end portion) of the trigger rod 52 engages with the inclined surface 50a of the deadlock member situating the deadlock member 50 in the disengaged position so that the deadlock member 50 is not engaged with the lock bolt 39, as illustrated in FIG. 2.
[0029]
As illustrated in FIG. 2, when the deadlock member 50 is positioned in the disengaged position with respect to the lock bolt 39, the lock bolt 39 is able to freely move between the locked position and the unlocked position.
[0030]
FIG. 5 is a perspective view of the subassembly consisting of the attaching member to which the trigger rod 52 and the second spring 53 are attached. FIG. 6 is a side view of the subassembly.
As shown in these figures, the trigger rod 52 has an elongated guide hole 52b in the longitudinal direction of the trigger rod 52. The attaching member 54 has a projecting guide portion 54b in the outer portion of the attaching member 54. The projecting guide portion 54b is inserted into the elongated guide hole 52b and provided in such a manner that the trigger rod 52 is able to move with respect to the attaching member 54.
[0031]
The second spring 53 is operatively connected to a spring receiving portion 52c for the trigger rod 52 and a spring receiving portion 54c for the attaching member 54, wherein the second spring biases the trigger rod 52 toward a portion 32a of the cylinder lock 32. Further, the attaching member 54 has an opening 54a through which the front portion of the cylinder lock 32 is disposed and the attaching member 54 has a screw hole 54d which enables the attaching member 54 to be attached to the body.
[0032]
In the subassembly of FIG 6, which includes the attaching member 54, the second spring 53 is arranged substantially parallel to the longitudinal direction of the trigger rod 52. In this embodiment of the subassembly, the trigger rod 52 experiences a rotational force (in FIG 6, for example, the rotational force is in the anticlockwise direction) from the projecting guide portion 54b which acts as the fulcrum.
[0033]
Due to this rotational force, the portions P of the wall of the elongated guide hole 52b of the trigger rod 52 become pressed against the projecting guide portion 54b; moreover, at least one portion of the trigger rod 52 becomes pressed against the side portion Q of the 10 attaching member 54 near the spring holding portion 54c. These contact pressure forces provide the support that allows the trigger rod 52 to become attached to the attaching member 54.
Further, because each the spring holding portions 52c, 54c form recessed grooves in which the second spring 53 is disposed, the second spring does not easily become uncoupled with the attaching member 54.
[0034]
As shown in FIG.7, the subassembly, which includes the attaching member 54, is inserted into the body 31 through the mouth 31a and is fixed to the body 31 by means of a fixing screw 55 prior to installing the cylinder lock 32 within the body 31.
When the subassembly has been installed, the trigger rod 52 is arranged in a recessed slide groove 31e, which is formed so as to be an elongated passage extending along the front-rear direction of the body 31 within the body 31.
[0035]
The installed trigger rod 52 is arranged between the attaching member 54 and the side of body 31 in the radial direction of the body 31 in such a manner that the trigger rod 52 is able to slide within the recessed slide portion 31e.
The range of movement of the trigger rod 52 toward the mouth 31a is limited by the projecting guide portion 54b of the attaching member 54 which comes into contact with the end wall of the elongated guide hole 52b of the trigger rod 52.
[0036]
As described above, the trigger rod 52 is disposed within the recessed slide portion 31e of the body 31 so as not to become disengaged.
The setup also enables the body 31, including parts such as the attaching member 54 and the trigger rod 52, to be manufactured separately from the cylinder lock 32, and then later transfer the various components to a different factory where they can be assembled.
[0037]
The steering lock device of this embodiment is assembled in the manner as described below.
First, the lock bolt 39 and the joint 40 are coupled to each other; then the spring 41 is arranged between the lock bolt 39 and the cam 38; and then the first end portion of the joint 40 and the spring 41 are operatively connected to the cam 38. Thereafter, this assembled configuration is installed within the body 31.
The parts are assembled in a state in which that the cam 38 is positioned in the unlocked position (ACC position), which enables the lock bolt 39 to also be arranged in the unlocked position, i.e. when the lock bolt 39 is not protruding outside from the body.
[0038]
Further, the deadlock member 50 is inserted through the insert hole 3Id and arranged in the recessed portion 31b located on the lateral portion of the body 31. The first spring 51 is arranged between the enlarged-diameter portion 50b of the deadlock member 50 and the lid 35 which covers and secures the first spring and the deadlock member.
As shown in FIG. 7, the front portion of the deadlock member 50 is situated so that the front portion is in contact with the side surface of the lock bolt 39 which is the default position. An opposing force from the contact with the lock bolt acts against the biasing force of the first spring 51.
[0039]
Subsequently, the subassembly which includes the attaching member 54 is installed within the body, thereby achieving the assembled state shown in Fig 7. Thereafter, the cylinder lock 32 is installed through the mouth 31a.
[0040]
Once the cylinder lock 37 has been installed, a portion 32a of the cylinder lock 32 causes the trigger rod 52 to move forward against the biasing force of the second spring 53, and the inclined portion 52a of the distal end of the trigger rod 52 comes into contact with the inclined surface 50a of the deadlock member 50. As a result, the deadlock member 50 is situated in the disengaged position with respect to the lock bolt 39, as shown in
FIG 2.
[0041]
Alternatively, if the steering is locked as shown in FIG. 2 and the cylinder lock 32 is intentionally removed, the portion 32a of the cylinder lock 32 becomes separated from the trigger rod 52 as shown in FIG. 8. As a result of the release of trigger rod 52 because of the removal of the cylinder lock 32, the trigger rod 52 moves backward (to the right in FIG.
8) because of the biasing force of the second spring 53.
[0042]
Since the front portion of the trigger rod 52 is separated from the deadlock member 50, the deadlock member 50 is moved by the biasing force of the first spring 51 causing the deadlock member to protrude into the slide hole 31c of the lock bolt 39. The protruded deadlock member 50 prevents the lock bolt 39 from moving into the unlocked position and thus the lock bolt 39 keeps the steering locked.
Consequently, even if the cylinder lock 32 is intentionally removed in order to steal the vehicle, the steering lock device enables the steering to remain locked.
[0043]
With respect to the outer portion of the body, only a minimal cover (for example, the lid 35 of the above embodiments) for covering the parts of the deadlock mechanism is needed. This setup decreases the risks of successfully breaching or removing a cover, and consequently prevents the release of the steering lock. Accordingly, the steering lock device improves the antitheft capability.
[0044]
FIG. 9 shows a modified embodiment in which a second spring 53 is arranged within the elongated guide hole 52b of the trigger rod 52.
In the modified embodiment, the second spring 53 is arranged between the wall forming the elongated guide hole 52b and the projecting guide portion 54b. The projecting guide portion 54b has a hook portion 54e for operatively connecting with the elongated guide hole 52b.
[0045]
The hook portion 54e allows for the trigger rod 52 to be operatively attached to the attaching member 54.
This configuration also forms a subassembly which includes the attaching member 54 to which the trigger rod 52 and the second spring 53 are attached.
[0046]
