Abstract
The present lock construction, for securing a movable object to a fixed object, includes a housing having an interior cavity and an elongated member having a first portion secured within the housing and a second portion slidably received within the housing. The elongated member is slidable within the passageway to a locked position, securing the movable object to the fixed position and to an unlocked position, releasing the object from the fixed object. First and second members are slidably disposed in the housing and are movable to engage the cable in the locked position. A rotatable locking mechanism is disposed within said housing and is engageable with the first member to permit slidable movement of the first member and thereby allow slidable movement of the elongated member to different locked positions. The rotatable locking mechanism is also engageable with the second member to permit slidable movement of the second member and thereby prevent movement of said elongated member in the locked position.
Description




BACKGROUND OF THE INVENTION




The present invention relates generally to a lock construction and particularly to a cable lock for securing items such as bicycles, skis or other movable objects to a bar, post or some other fixed objects. These items are typically portable and are often used to transport the user to different locations such that it is frequently desirable to secure these items to a fixed object that is easily found nearby. Moreover, these movable and fixed objects are typically constructed in different sizes and configurations that is additionally desirable to secure these items in a manner that is adaptable to the various shapes, sizes and configurations of the movable and fixed objects.




Several devices have been developed to accommodate the securing of various movable objects to fixed objects. U.S. Pat. No. 5,791,170 to Officer discloses a portable locking device having three operating positions, namely an unlocked position, a ratchet position and a locked position. The locking mechanism includes an eccentric positioning cam that is mounted on the positioning cam and is adapted to engage the cable as the cable is fed through the lock. Turning the key in the locking mechanism effects movement of the positioning cam such that the clamping member is engageable with the cable at different locations of the clamping member. The positioning cam is otherwise connected on one side to a spring that is secured in a cutout of the lock housing for urging the positioning cam in a rotative direction. The construction of the Officer portable locking device relies on the rotor spring to retain the lock in various operational positions. Any rotation or movement of the rotor, due to vibration or external tampering, would invariably compromise the integrity of the lock. Additionally, the structure of the Officer lock affords only a point contact between the clamping mechanism and the cable that further comprises the ease of operation afforded by the lock.




U.S. Pat. No. 2,190,661 to Hauer discloses another cable lock having a locking cam with a corrugated cam end that is used to allow the locking cam to depress the cable into a recess in the housing. A cam spring is mounted within the housing to displace the cam against the cable with sufficient force to engage and lock the cable. Although the corrugated cam increases the gripping force on the cable, the Hauer lock construction is similar to the Officer lock construction in that it also relies only on the rotatable locking cam without other structural supports to maintain the various operational positions of the lock. Thus, the level of security and the ease of operation provided by the Hauer lock are similarly less than desirable.




SUMMARY OF THE INVENTION




The present invention is directed to a lock construction for securing a movable object to a fixed object. The lock construction comprises a housing having a passageway extending through the housing. An elongated member has a first portion that is secured within the housing and a second portion that is slidably received within the passageway. The elongated member is slidable within the passageway to a locked position, securing the movable object to the fixed object, and to an unlocked position, releasing the movable object from the fixed object. A first member is disposed in the housing and is movable to engage the elongated member in the locked position. A second member is also slidably disposed within the housing and is operatively associated with the first member to allow slidable movement of the first member. A rotatable locking mechanism is disposed within the housing and is engageable with the first member to permit slidable movement of the first member and thereby allowing slidable movement of the elongated member to different locked positions. The rotatable locking mechanism is also engageable with the second member. In engaging the second member, the locking mechanism permits slidable movement of the second member and thereby preventing movement of said elongated member in the locked position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIG. 1

, the lock construction


1


of the present invention is shown having two engaging covers


2


and


3


that are mated to each other to form a lock housing


4


. The lock construction


1


further includes an elongated member, preferably in a form of a cable


5


, with first and second portions


6


and


7


forming the length of the cable


5


. The end of the first portion


6


is secured within the housing


4


, and the second portion


7


is slidably received in a passageway


8


extending through the lock housing


4


. The cable


5


is securable to the lock housing


4


, and depending on the extent to which the second portion


7


is inserted within the housing


4


, the cable


5


forms a loop


9


of variable sizes. Thus, by threading the cable


5


about a movable object to be secured, such as a bike, and around a fixed object, such as a pole, before inserting the first portion


7


into the housing


4


, the cable


5


may be pulled through the passageway


8


such that the loop


9


is dimensioned to tightly secure the bike to the pole.




A keyway


10


, better shown in

FIG. 2

, is located on the front of the lock construction


1


for inserting an authorized key to operate the lock construction


1


. Preferably a pivotable keyway cover


11


is disposed over the keyway


10


to protect against dirt or other debris that may enter the lock housing


4


through the keyway


10


. The keyway


10


is connected to a rotatable locking mechanism


12


disposed in the interior cavity of the housing


4


. The locking mechanism


12


includes a lock cylinder, not shown in

FIG. 2

, which is preferably a conventional tumbler lock assembly having a plurality of tumbler pins that are fitted for the authorized key. Other locking mechanisms, such as wafer tumblers or electronic access devices with key-pad entry may also be used.




The lock construction


1


has various operational positions in which the cable


5


can be manipulated to form substantially any size loop


9


with the lock housing


4


. The lock construction


1


has an unlocked position in which the cable


5


is slidably receivable in the passageway


8


and is movable in a first direction, the direction of insertion, to form smaller loops


9


with the housing


4


. In the unlocked position, the cable is also slidably removable in a second direction, opposite the direction of insertion, to form larger loops


9


with the housing


4


and eventually to be removed from the housing


4


for releasing the objects secured.




The lock construction


1


has a first locked position, or a cinch position, in which the cable


5


is also slidably receivable in the passageway


8


in the first direction. The cinch position differs from the unlocked position, however, in that the cable


5


cannot be released in the second direction. The cable


5


is prevented from movement in the second direction through the housing


4


and is only allowed to move in the first direction to allow the user great ease in tightening or cinching the cable


5


around the object and the fixture.




The lock construction


1


further includes a second locked position, or the dead locked position, in which the cable


5


is prevented from any movement in the first or second directions through the passageway


8


. The user selects these operational positions by inserting the authorized key into the keyway


10


and rotating the key to the desired operational position, the details of which will be discussed in greater depth hereinafter.




Markers are preferably disposed on the front of the lock construction


1


for visually assisting the user in locating these operation positions. Marker


13


marks the key position for locating the lock


1


in the unlocked position. Marker


14


marks the key position for locating the lock


1


in the cinch position. Finally, Marker


15


marks the key position for locating the lock


1


in the dead locked position. Additional markers, such as an arrow


16


, may also be used to show the direction of insertion of the cable


5


. With the various operational positions so marked, the operation of the lock construction


1


is greatly simplified since the user needs only to insert and rotate the authorized key to the marked location for performing the desired operation of the lock construction


1


.




Referring now to

FIG. 3

, the cover


2


of the housing


4


forms an exterior surface


17


and defines one-half of an interior cavity


18


. The portion of the passageway


8


formed by the cover


2


is shown extending from one side of the exterior surface


17


to the other through the interior cavity


18


. An opening


19


is formed by the passageway


8


on the exterior surface


17


to slidably receive the cable


5


through the passageway


8


. The other end of the cable


5


, namely the end of portion


6


, is preferably received and secured in a cap


20


that is anchored by a pin


21


in interior cavity


18


. The pin


21


securely anchors the end of portion


6


within the interior cavity


18


while allowing the first portion


6


of the cable


5


pivotable movement about the pin


21


. The pivotable movement of the first portion


6


allows greater ease in manipulating the cable


5


during operation of the lock construction


1


. The second end


7


of the cable


5


is insertable into and through the passageway in the first direction, as shown by arrow


3




A


, for tightening the loop


9


of the cable


5


through the passageway


8


. The second portion


7


of the cable


5


is also slidable in the second direction, as shown by arrow


3




B


, for loosening the loop


9


in releasing the cable


5


from the housing


4


.




An extension


22


extends from each of the covers


2


and


3


of the housing


4


, only one of which is shown in

FIG. 3

, to form the top portion of the passageway


8


. Preferably the extensions


22


include a toothed interior surface having toothed protrusions


23


to assist with grasping and retaining the cable


5


as it is inserted through the passageway


8


. Most preferably, each of the protrusions


23


is arranged in an asymmetrical fashion, with one side of the toothed protrusion longer than the other with the protrusion pointing in the axially inward and generally in the direction of insertion


3




A


.




The asymmetric protrusions


23


are oriented to increase the level of security provided by the lock


1


. For example, toothed protrusions that extend perpendicularly from the interior surface of the passageway


8


assist with grasping the cable


5


, as stated earlier, by having the protrusions


23


physically engage or dig into portions of the cable


5


. Exerting substantial force by pulling on the cable


5


with the protrusions


23


in engagement with the cable


5


can form grooves on the cable


5


and thereby compromising the level of security provided by the lock


1


by preventing the formation of grooves on the cable


5


, even when the cable


5


is being tampered with.




Forming the base portion of the passageway


8


is a first member


24


that is slidably disposed in the interior cavity


18


to engage the cable


5


. The first member


24


is resiliently biased toward the cable


5


by a first spring


25


that is disposed in a recess


26


in the housing


4


. As shown in

FIGS. 4 and 5

, the first member


24


has preferably parallel front and back sides


27


and


28


, a top side


29


and a bottom side


30


. The top side


29


defines a recess


31


extending across the entire top side


29


for engaging the cable


5


, as better shown in FIG.


5


. Thus, the recess


31


forms the bottom portion of the passageway


8


. As the first member


24


is biased by the spring


25


in a slidable fashion, the diameter of the passageway


8


is variable according to the slidable movement of the first member


24


when biased by the spring


25


. As with the protrusions


23


disposed on the extension


22


, toothed protrusions


33


are also preferably disposed on the interior surface of the recess


31


to assist with grasping and engaging the cable


5


. The protrusions


23


and


33


, respectively shown in

FIGS. 3 and 5

, are configured as parallel ridges extending circumferentially across a portion of the passageway


8


. Other protrusion configurations, having a individual saw tooth configuration or staggered points may also be used in the passageway


8


to assist with grasping and engaging the cable


5


.




The bottom side


30


of the first member is sloped from the front side


27


downwardly toward the back side


28


, as shown in FIG.


4


. Referring back to

FIG. 3

, the sloped side


30


, is in an abutting contact with an incline


35


disposed in the housing


4


when the lock


1


is assembled. The incline


35


is preferably integrally constructed with the housing


4


to guide the slidable movement of the first member


24


when biased by the spring


25


. The passageway


8


further includes a longitudinal axis


8




A


, as shown in

FIG. 3

, with which incline


35


forms a first angle Θ


1


. Similarly, the sloped bottom side


30


of the first member


24


forms an angle Θ


2


with a line L


1


that is parallel to the axis


8




A


, as shown in FIG.


4


. Preferably, angle Θ


1


of the incline


35


is equal to angle Θ


2


of the bottom side


30


such that the passageway


8


has a substantially uniform diameter extending through the interior cavity


18


.




As stated previously, the first member


24


is slidable toward the cable


5


along the incline


35


by the force of the first spring


25


. Preferably, the first spring


25


is oriented such that the resultant force of the spring


25


is in a direction substantially parallel to the incline


35


. Thus, the first member


24


is slidable along the incline


35


with the sloped bottom surface


34


in abutting contact therewith, further maintaining a substantially uniform diameter through the passageway


8


.




The first member


24


further includes a cutout


36


extending between the bottom side


30


and the back side


28


. The cutout


36


defines an angle Θ


3


with a line L


2


that is perpendicular to axis


8




A


, as shown in FIG.


4


. Additionally, a first knob


37


extends from the first member


24


. The details of the interface between the cutout


36


and the knob


37


will be discussed in greater details hereinafter.




Referring back to

FIG. 3

, a second member


38


is also disposed in the housing


4


for slidable movement therein. The second member


38


preferably has substantially parallel sides


39


, a top side


40


and a bottom side


41


, best shown in FIG.


6


. Similar to the sides


27


-


30


of the first member


24


, the sides


39


-


41


of the second member


38


may be formed having perpendicular edges or rounded edges. Like the first member


24


, the second member


38


is also resiliently biased in the interior cavity


18


by a second spring


42


that is disposed in a recess


43


of the housing


4


. The second spring


42


biases the second member


38


upwardly toward the first member


24


. The opt side


40


of the second member


38


forms a wedge


44


that has a sloped surface


45


. The sloped surface


45


defines an angle Θ


4


with a line L


3


perpendicular to the longitudinal axis


8




a


, as shown in FIG.


6


. Preferably, Θ


3


of the cutout


36


and Θ


4


of the wedge


44


are selected to correspond to each other such that upward movement of the second member


38


toward the first member


24


causes the wedge


44


to engage the cutout


36


of the first member


24


in an abutting contact. A second knob


46


is disposed on the second member


38


, the function of which will be discussed hereinafter.




Referring back again to

FIG. 3

, the rotatable locking mechanism


12


discussed previously has first and second tabs


47


and


48


extending from the locking mechanism


12


and are rotatable therewith to respectively engage the first and second member


24


and


38


. As shown in

FIG. 3

, the lock


1


is in the unlocked position with the first tab


47


engaging the first knob


37


against the biasing force of the spring


25


to prevent displacement of the first member


24


by the first spring


25


. The passageway


8


is therefore clear for insertion of the cable


5


. As stated above, the top side


29


of the first member


24


and the bottom side of the extension


22


respectively form the top and bottom sides of the passageway


8


. Thus, the first tab


47


preferably engages the first knob


37


such that the passageway


8


has a diameter extending therethrough that is sufficiently larger than the diameter of the cable


5


to ensure greater ease in the insertion of the cable.




Additionally a periphery portion


49


, shown as having an arcuate shape, extends on the periphery of the locking mechanism


12


between the first and second tabs


47


and


48


. The arcuate portion


49


engages the second knob


46


to displace and hold the second member


38


against the biasing force of the second spring


42


, preventing upward movement of the second member


38


. Accordingly, the second member


38


is prevented from engaging the cutout


36


of the first member


24


. Thus, the orientation and disposition of the locking mechanism


12


, with the first member


24


prevented from moving along the incline


35


to engage the cable


5


and the second member


38


prevented from engaging the first member


24


, renders the lock construction


1


in the unlocked position. Accordingly, the cable


5


is free to slide in either the first or the second direction shown by the arrow


3




A


and


3




B


to tighten or loosen the loop


9


.




As the locking mechanism


12


is rotated about 90° in a clockwise rotation, as shown by the arrow


7




A


in

FIG. 7

, to the cinch position as marked by marker


14


in

FIG. 2

, the first tab


47


is moved out of engagement with the first knob


37


and the first member


24


therefore slides along the incline


35


biased by the first spring


25


to engage the cable


5


and to contract the passageway


8


. Preferably, the instant the first tab


47


of the locking mechanism


12


is rotated out of engagement with the first knob


37


, the force of the first spring


25


begins biasing the first member


24


in the direction shown as arrow


7




B


against the cable


5


. The force of the first spring


25


slides the first member


24


along the incline


35


until the first member


24


is wedged securely between the cable


5


and the incline


35


. The wedged position of the first member


24


prevents the cable


5


from being pulled in the second direction


7




D


. Any force pulling on the cable


5


in the second direction


7




D


causes the first member


24


to be “wedged” tighter between the cable


5


and the incline


35


, thereby more securely locking the cable


5


.




Moreover, while the lock


1


is in the cinch position with the locking mechanism


12


rotated 90° from the unlocked position, the arcuate portion


49


of the locking mechanism


12


retains engagement with the second tab


48


of the second member


38


. Thus, the wedge


44


of the second member


38


is prevented from contacting the first cutout


36


and the first member


24


is allowed to move against the force of the spring


25


when sufficient pulling force is exerted on the cable


5


in the first direction, as shown by arrow


7




C


. As the cable


5


is prevented from slidable movement in the second direction,


7




D


, the loop


9


can be pulled through the housing


4


to form smaller loops


9


or to tighten around the object and the fixture.




When the cable


5


is sufficiently tightened about the object and the fixture, the locking mechanism


12


may be rotated yet another 90° in the clockwise direction, as shown by arrow


8




A


in

FIG. 8

, to the dead position, shown as marker


15


in FIG.


2


. Referring back to

FIG. 8

, the rotation of the locking mechanism


12


from the cinch position rotates the arcuate portion


49


out of engagement with the knob


46


. Accordingly, the second member is allowed to move upwardly by the biasing force of the second spring


42


such that eventually the wedge


44


of the second member


38


is in abutting contact with the cutout


36


or the first member


24


. Once the wedge


44


is in abutting contact with the cutout


36


, the first member


24


is prevented from slidable movement along the incline


35


in either direction, and the cable


5


is thereby prevented from being tightened or released from the housing


4


. The abutting contact between first and second member


24


and


38


securely locks the cable


5


in the passageway


8


by positively filling the void spaces between the locking mechanisms


12


and the cable


5


. Accordingly, the cable


5


is secured against any inadvertent rotation of the locking mechanism


12


due to vibration when the lock


1


is exposed to impact from an external force. Moreover, inadvertent rotation of the locking mechanism


12


is also prevented when minor movement of the first or second members


24


and


38


is caused by tampering with cable


5


.




Rotating the locking mechanism


12


in a counterclockwise direction thereafter, as shown by the arrow


9




A


in

FIG. 9

, engages the second tab


48


with the second knob


46


, displacing the second member


38


in a downward direction shown by arrow


9




B


against the biasing force of the spring


42


. Further rotation in the counterclockwise direction of the locking mechanism


12


, further displaces the second member


38


until the arcuate portion


49


is again in engagement with the second knob


46


. Accordingly, the second member


38


is reverted back away from the first member


24


, and the lock construction


1


is again in the cinch position, allowing movement of the cable


5


in the first direction only, as discussed previously.




Further counterclockwise rotation of the locking mechanism


12


, as shown by arrow


10




A


of

FIG. 10

, reengages the first tab


47


with the first knob


37


. The first tab


47


engages the first knob


37


against the biasing force of the first spring


25


, as shown by arrow


10




B


, displacing the first member


24


away from the cable


25


, and positions the lock construction


1


in the unlocked position. As the arcuate portion


49


of the locking mechanism


12


is still engaged with the second knob


46


, the second member


38


is out of engagement with the first member


24


. Thus, the cable


5


is slidable from the lock housing


4


in both the first and second directions, allowing removal therefrom.




The angles Θ


1


and Θ


2


of the incline


35


and the bottom side


30


of the first member


24


will generally determine the travel distance required by the first member


24


to engage the cable


5


. Accordingly, depending on the desired overall configurations and dimensions of the lock housing


4


, angles Θ


1


and Θ


2


may be selected to accommodate any desired size of the housing


4


. Preferably, the angle Θ


1


and Θ


2


are between about 12° to 25°. Most preferably, angles Θ


1


and Θ


2


are between about 22°-25°. However, other angles may be used with consideration to the compression force of the first spring


25


and the compact size of the housing


4


to ensure proper operation of the lock construction


1


.




Similarly, angles Θ


3


and Θ


4


determine the vertical travel distance of the second member


38


before the wedge


44


of the second member


38


engages in abutting contact with the first member


24


. Angles Θ


3


and Θ


4


are selected to ensure proper engagement between the first and second members


24


and


38


. Preferably angles Θ


3


and Θ


4


are between 45° to 55°. Most preferably, angles Θ


3


and Θ


4


are about 50°.




All the angles and dimensions of the operational elements as described above can be modified accordingly to achieve the desired overall dimension of the lock housing


4


and proper operation thereof. Modification in one of these elements may result in a cascading effect on the dimensions of the remaining elements. For instance, if Θ


1


is increased and the slope of the incline


35


is correspondingly increased, the vertical and horizontal travel of the first member


24


to engage the cable


5


is decreased. Decreasing the vertical travel of the first member


24


accordingly decreases the vertical travel required by the second member


38


to ensure proper contact between the wedge


44


and the cutout


36


. The overall dimension of the lock housing


4


can therefore be minimized. On the other hand, sufficient movement of the first and second members


24


and


38


is desirable to ensure that the security level of the lock cannot be easily compromised due to vibration and tempering caused by external sources. Moreover, a significant increase in Θ


1


and the slope of the incline


35


will increase resistance against sliding the cable


5


in the first direction when the lock is in the cinch position. Additionally, the compression force of the first and second springs


25


and


42


also impacts the ease of operation of the lock and therefore the level of security thereby provided.




An illustrative operation of the lock construction


1


will now be described with respect to the preferred embodiment. To secure an object such as a bicycle to a fixture such as a pole, the user takes the lock


1


in the unlocked positions, marked as Marker


13


in

FIG. 2

, and threads or loops the second end


7


of the cable


5


through portions of the bicycle and wrap the cable


5


around the pole before inserting the second end


7


through the opening


19


into the passageway


8


. Since the first tab


47


is in contact with the first knob


37


, the passageway


8


is maintained sufficiently cleared to allow ease in inserting the cable


5


. Once inserted, the cable


5


is freely slidable in and out of the lock housing


4


.




With the second end


7


of the cable


5


sufficiently pulled through the lock housing


4


, the user may turn the authorized key within the keyway


10


and rotate the lock mechanism


12


to the cinch position, marked as Marker


14


, in FIG.


2


. The first member


24


is therefore biased toward the cable


5


by the biasing force of the spring


25


to engage the inserted portion of the cable


5


. Thereafter, the user is able to pull the cable


5


through the passageway


8


in the first direction against the force of the spring


24


until the cable


5


forms a tight loop


9


around the bike and the pole the construction of first member. The spring


25


wedges the first member


24


against the cable


5


and in the incline


35


such that the cable


5


is prevented from slipping.




Once the cable


5


is sufficiently tightened about the bike and the pole, the user may rotate the key to the dead locked position, marked as Marker


15


in FIG.


2


. The second member


38


is thereby allow to engage the first member


24


, preventing the first member


24


from movement against the incline


35


away from the cable


5


. Accordingly, the cable


5


is prevented from movement in either the first or second directions, and the bike is securely locked to the pole.
