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.
