Description




INTRODUCTION AND BACKGROUND




Copending application Ser. No. 09/028,138 filed on Feb. 23, 1998 [agent ref. 100-02] (the disclosure of which are included by reference herein) disclose novel methods and apparatuses for securing one end of a cable to another end of cable, for example, to secure the ends of a cable for attaching a recreational craft, for example, a surfboard, to the hood or roof of a car or truck. The present invention is an improvement of the earlier inventions and includes an improved means of locking the devices disclosed in the earlier application to make these devices easier and safer to use and more appealing to the eye.




U.S. Application Ser. No. 09/028,138 discloses a device for securing a cable consisting of a set of u-shaped brackets or channels hinged at one end. The unhinged end of one bracket includes an adjustable device for securing the first end of a cable, for example, a plastic-covered, braided steel cable. The unhinged end of the second bracket also includes an adjustable arrangement for securing the second end of a cable. The characterizing feature of the invention disclosed in application Ser. No. 09/028,138 is that when the second bracket is rotated about the hinged end it engages the first bracket while concealing the devices used to secure the cable to the brackets. The brackets also include means for securing the engaged brackets, for example, a perforated tab for a padlock, to prevent the two brackets from being disengaged and the cable ends released.




The present invention provides for further improvements to the devices disclosed in application Ser. No. 09/028,138. For example, in one embodiment of the present invention, the means by which the first cable end is secured to the first bracket allows for ease of securing and tightening the first cable to the first bracket. The same means for securing and tightening is also more easily released when the second bracket is disengaged from the first bracket.




In addition, where the devices described in the above-referenced applications have been shown to provide a simple and effective means of securing the ends of cables, the locking mechanism described in those applications can be cumbersome and prone to tampering by others. The present invention overcomes these limitations of the devices disclosed in the above applications by introducing means of locking the devices incorporating a combination lock or lock-and-key arrangement, for example, a locking arrangement having a more user-friendly push-button release.

DETAILED DESCRIPTION OF THE FIGURES





FIG. 1

illustrates an isometric view of the present invention


10


in which some of the device has been removed to clarify the invention. Similar to the device shown in copending U.S. application Ser. No. 09/028,138, the device


10


includes a first u-shaped channel


11


and a second u-shaped channel


12


. Channels


11


and


12


may be fabricated from commercially available channels or tubing (for example, a rectangular tube cut in half) or may be fabricated or formed from metal plate, preferably stainless steel plate, by forming or welding or other machining or fabrication processes. The two channels are hinged at


13


such that the second channel can rotate about the hinged end. The width of the second channel


12


is preferably larger than the width of the first channel so that when the second channel


12


is rotated into engagement with the first channel


11


, the second channel


12


covers and conceals the first channel


11


.




The first channel


11


includes means


14


for securing a cable


15


. The means


14


includes a set of rigid members or blocks


16


and


17


that are secured to channel


11


, for example, by welding. These blocks


16


,


17


form a wedge shaped cavity through which the cable


15


passes as it engages means


14


. Means


14


also includes a slidable device


18


(more clearly shown in

FIG. 2

) consisting or comprising a rectangular flat plate


19


, a v-shaped wedge piece


20


, and a circular disk


21


. The wedge piece


20


and the disk


21


are attached to the flat plate


19


, and the flat plate


19


engages slots in blocks


16


,


17


(shown at


22


) such that the slidable device


18


slidably engages the slots in blocks


16


,


17


in the direction shown by double arrow


23


. Channel


11


also includes opening


46


for passing the cable


15


into the channel so that the cable can be engaged with retaining device


14


and then excess cable can pass out of channel


11


.




The v-shaped wedge piece


20


includes a cavity


24


for accepting a spring and plunger


26


(see FIG.


3


). The wedge piece


20


is shaped similar to blocks


16


,


17


such that the outer surfaces of wedge


20


and the inside surfaces of blocks


16


,


17


act to capture and retain the cable


15


that passes between them. The outer surface of wedge


20


and the inside surfaces of blocks


16


,


17


form an angle of about 30 to 70 degrees with the axis of the channel


11


, preferably an angle of about 40 to 60 degrees. The spring


25


is preferably attached to either wedge


20


or plunger


26


, but spring


25


may not be attached at either end.




The disk


21


may be rigidly fixed to plate


19


or it may rotate about a central pin


21


′ which is fixed to plate


19


. Disk


21


may also have a grove on its perimeter similar to a pulley or sheave to accept and retain the cable


15


.




The interaction of the slidable device


18


having a wedge


20


and disk


21


with the cable end


15


provides an advantageous feature of the present invention. Specifically, when tension is created in cable end


15


, for example during installation or under loading during use, the tension in the cable exerts a load on the disk


21


which is transferred to the wedge


20


and to the cable end


15


. That is, this invention is self-clamping: tension created in the cable end


15


provides compression between the wedge


20


and the blocks


16


,


17


to provide a clamping load on the cable


15


.




Plunger


26


is connected to channel


12


by means


27


(again, see

FIG. 3

for clarity) such that when channel


12


is rotated about the hinged end at


13


, the plunger


26


is deflected against the spring


25


and the spring


25


in cavity


24


imposes a load on the v-shaped wedge


20


. This spring load compresses the wedge


20


against the cable


15


such that the cable is wedged between wedge


20


and blocks


16


,


17


. The means


27


may be one or more rigid rods or bars, for example rods


28


and


29


shown in FIG.


3


. Rod


28


is attached to plunger


26


, preferably rotatably attached to allow some freedom for the rod to rotate, for example, by means of the screw


30


. Though a set of single rods may extend from plunger


26


to the channel


12


adjacent the hinged connection


13


, in a preferred embodiment, two or more rods or bars


28


and


29


cooperate by means of stops


31


,


32


, and


33


. These stops are shown as circular disks, but any form of physical obstruction to sliding movement may be used. Stop


31


is rigidly attached to rod


28


. Stops


32


and


33


are rigidly attached to rod


29


but are slidably attached to rod


28


by means of through holes. The curved end


34


of rod


28


also acts to detain the movement of rod


29


when stop


33


impinges the end


34


. The rods or bars


28


and


29


are allowed to move relative to each other until the stops are encountered and then the force exerted on one rod is transmitted to the other rod. This permits some amount of free movement or “play” in the movement of channel


12


without imposing a load on spring


25


, wedge


20


, and cable


15


.




Channel


12


also includes features that are disclosed in copending application Ser. No. 09/028,138. For example, channel


12


includes means


35


for adjustably attaching a cable having a T-shaped end. As shown in copending application Ser. No. 09/028,138, the arms of a T-shaped end of a cable pass through the opening


36


in channel


11


and engage the opposite u-shaped openings


37


in side plates


38


. The tension in the cable can be adjusted by appropriately engaging the arms of the T-shaped end in different sets of opposing u-shaped openings


37


(only one set of unshaped openings is shown in FIG.


1


).




Channel


12


also includes an elongated slot


39


in the end of the channel opposite the hinged end


13


. When the channel


12


is rotatably engaged with channel


11


, the slot


39


engages the corresponding perforated tab


40


in channel


11


, having through hole


41


. The tab


40


and hole


41


are so designed to accept a locking device such as a conventional padlock.




Also, according to this invention the channel


12


includes a plate


42


positioned perpendicular to the top surface of channel


12


and having one or more, preferably two or more, u-shaped openings


43


. These openings


43


are designed to retain any excess length of cable


15


that protrudes beyond the attachment device


14


and opening


46


. The unshaped openings


43


are designed to be slightly less in diameter than the diameter of cable


15


, in particular, a plastic covered cable, so that the cable can be inserted into two or more of the openings


43


and retained in openings


43


during transport or storage.





FIG. 4

illustrates another embodiment of the present invention which is very similar to the embodiment shown in FIG.


1


. In the embodiment shown in

FIG. 4

, a device


110


having channels


111


and


112


for retaining cable


115


is similar to device


10


having channels


11


and


12


. Rods or bars


28


,


29


of

FIG. 1

are replaced by bars


128


. Bars


128


, typically steel bars with a rectangular cross section, are used to attach the channel


112


to the plunger


126


which deflects spring


125


(similar to spring


25


), as shown in FIG.


5


.




The operation of device


10


(


110


) will be described with respect to FIG.


1


. The order of operation is not critical to the invention. First, a T-shaped bar of cable (not shown) is inserted into opening


15


and the arms of the are engaged with a set of unshaped openings


37


in plates


38


. Then the cable


15


is inserted into the opening


46


; passed between one of the passages between blocks


16


,


17


and wedge


20


; passed about disk


21


; then passed between the other passage between blocks


16


,


17


and wedge


20


; and then passed out of opening


46


. The free end of cable


15


can then be drawn taunt around the disk


21


by pulling on cable


15


. The channel


12


is then rotated about hinged end


13


so that it engages channel


11


. In so doing, the rods


28


,


29


(or bars


128


of

FIG. 4

) are compressed by the rotation of channel


12


and deflect the plunger


26


(


126


) against the spring


25


(


125


). The spring


25


(


125


) deflects the v-shaped wedge


20


so that the wedge


20


compresses the cable


15


between the outer surface of wedge


20


and the inside surfaces of blocks


16


,


17


. The resiliency of the spring


25


(


125


) provides for some relief in the clamping force on the cable


15


, thus, the cable is not crimped between the wedge


20


and blocks


16


,


17


, but the stiffness of the spring


25


(


125


) is so chosen so that the cable is held and undesirable slippage prevented when the channel


12


is engaged with the channel


11


. The engagement is secured by placing a locking device through hole


41


, such as a padlock. The excess cable of cable


15


can be inserted into slots


43


to secure it for transport or storage.




Again, as described in copending application Ser. No. 09/028,138, the engagement of channels


11


and


12


also conceals the attaching mechanisms


14


and


35


so that neither can be tampered with while the channels are engaged.





FIG. 6

illustrates a device used to provide the cable storage function of plate


42


and slots


43


in a clamping device as disclosed in copending application Ser. No. 09/028,138 (again, the disclosure of which is included by reference herein). As shown in

FIGS. 4

,


5


and


6


of application Ser. No. 09/028,138, one method of both retaining a cable in one channel and securing the two channels together is by means of a treaded nut-like device. The nut-like device functions to secure a cable end by compressing it beneath a plate and also provided means for securing the first channel to the second channel. That is, the nut-like device extends above the first channel and protrudes through the second channel and provides means for inserting a locking device, again, a padlock, such that the channels are secured together.




The device shown in

FIG. 6

of this application is another nut-type device


50


that can be used in the embodiments shown in application Ser. No. 09/028,138. Device


50


comprises or consists of a vertical plate


142


attached to a horizontal plate


47


having a threaded hub


48


which can be threaded on to a bolt or stud attached to, for example, channel


111


. In the embodiment shown, the vertical plate


142


and horizontal plate


47


are fabricated from a single plate by punching section


49


from a plate and bending the plate to form the horizontal plate


47


, essentially perpendicular to plate


142


. In the preferred embodiment shown, the cable retaining slots


143


provide a similar function to the slots


43


in plate


42


in FIG.


1


. That is, these slots provide a location for attaching and retaining excess cable


15


, that extends out of opening


46


in channel


11


, for storage or transport.





FIG. 7

illustrates a partial, isometric view of the preferred embodiment


210


of the present invention, marketed by the inventor under the trademark LASH & LOCK, for securing the first end of a cable (not shown) to a second end of a cable


211


. For example, the device


210


can be used to secure a kayak or windsurfboard (not shown) to the top of a car or to the back of a truck (also not shown). The device consists of a first elongated channel


212


, typically u-shaped in cross section, and a second elongated channel


213


, also typically u-shaped in cross section. The present invention is not limited to u-shaped channels, but can be used with any appropriate elongated member which provides the function of the channels described. Channels


212


and


213


are hinged for rotatable engagement at one end (for example, in a fashion similar o the way channels


11


and


12


are hinged in

FIG. 1

) In

FIG. 7

, channels


212


and


213


are shown in the fully-rotatably-engaged position. The channel


213


is typically wider than the channel


212


so that when the channels are rotated into engagement, channel


213


encloses and covers channel


212


so that the mechanism for securing the cable end


211


is protected from damage or tampering.




Cable end


211


typically comprises a taunt end


211




a


which extends around the object or is attached to the object being secured, for example, a surfboard; and a loose end


211




b


which extends out of device


210


after engaging the means for securing the cable


211


to the device (for example, a mandrel-type post or pin,


21


shown in FIG.


1


). The free-end


211




b


is typically drawn to snugly secure the object being retained.




At the opposite end of where the cable end


211


engages the device


210


, the channel


213


typically includes means


214


for engaging and securing the second cable end (for example, as shown in

FIG. 1

of application Ser. No. 09/028,138) to the device


210


. In the embodiment shown in

FIG. 7

(and more clearly shown in application Ser No. 09/028,138) the means


214


includes a rectangular cavity


215


, the walls of which include pairs of opposite unshaped openings


216


for accepting, for example, the arms of t-shaped element attached to the end of the second cable end (not shown).




According to the present invention, the device


210


includes a locking mechanism


217


, attached to channel


213


, comprising a housing


218


, a combination-lock mechanism


219


, and a release mechanism


220


. In the embodiment shown, the combination lock mechanism


219


consists of three rotatable wheels


221


having human-readable indicia


222


, for example, numbers or letters. The wheels


221


are preferably mounted on the side of the housing


218


as shown, but it is understood that these wheels may be located anywhere it is convenient, for example, these wheels may be located and accessible on the top of housing


218


. Though three wheels


221


are shown for inputting a sequence of numbers, it is understood that one or more wheels may be used, or some other form of conventional combination lock input may be used. For example, if desired, a single rotatable dial, for example, as is typical for a combination pad lock, may be located on the top of the housing


218


. But according to the present invention, for ease of access to the combination mechanism and for ease of attaching the cable ends, the wheels


221


are preferably located on the side of the housing


218


. Detailed illustrations of combination lock mechanism


219


are shown in

FIGS. 8 and 9

.




The release mechanism


220


is preferably a push-button release mechanism having a button


223


mounted in a boss


224


in the housing


218


. It is to be understood that other types of release mechanisms may be used for mechanism


220


, for example, mechanical levers or electro-mechanical devices. Detailed illustrations of release mechanism


220


are shown in

FIGS. 8 and 9

.




The locking device


210


also preferably includes means


225


for securing the loose, free end


211




b


of cable end


211


. In the embodiment shown in

FIG. 7

, this means comprises at least one, preferably a plurality of, u-shaped opening


226


located in a rectangular block


227


positioned on the top of housing


218


. These u-shaped openings preferably have a neck width


228


and a width


229


such that the cable end


211




a


can be snugly inserted and wound through one or more openings to retain the cable after securing the taunt cable end


211




a


to the device


210


. Though


3


u-shape openings


226


are shown in FIG.


7


and these openings are located on the top of housing


218


, it is understood that any number of openings may be used and that these openings may be located wherever convenient on housing


218


or on channel


213


. For example, the means


225


for retaining the loose cable end


211




b


may also be located on the face


230


of housing


218


or anywhere else where convenient. The openings


226


may also be rectangular or square in shape.




In a preferred embodiment shown in

FIG. 7

, the channel


213


also preferably includes an extension or “lip”


231


that can be grasped by the user to more easily separate channel


213


from channel


212


.





FIGS. 8 and 9

illustrate a top cross-sectional view and a side view, with the housing


218


partially removed, respectively, of the combination mechanism


219


and release mechanism


220


of housing


218


shown in FIG.


7


. In one embodiment of this invention, the combination mechanism


219


includes one or more rotatable wheels


221


having human-readable indicia


222


, for example, numbers or letters, on their periphery. These wheels are rotatable by the user to a pre-set sequence, as is conventional, to allow the release mechanism


220


to be deflected and the channels


212


and


213


separated. In the embodiment shown in

FIGS. 8 and 9

, the three wheels


221


have numerals


222


on their periphery, typically 0 to 9. The wheels


221


rotate in and are retained by circular recesses


232


in housing


218


and engage cylindrical, cup-shaped bushings


233


. The wheels


221


typically engage the bushings


233


by means of protrusions


234


on the outer surface of bushings


233


which engage recesses


235


in the inner diameter of wheels


221


. The bushings


233


slidably engage a rod or shaft


236


. Each bushing


233


possesses an internal cavity


238


having a bottom surface


239


. The rod


236


is physically connected to the release mechanism


220


. The rod


236


typically includes protrusions


237


on its surface and a flanged end


240


having a through-hole


241


. When the combination mechanism is in “locked” mode, the axial deflection of the rod


236


is prevented by the impingement of the protrusions


237


against the bottom surfaces


239


of the cavities


238


of bushings


233


. When “unlocked” the protrusions


237


are aligned with slots (not shown) in bushings


233


and the rod


236


is allowed to axially deflect. The axial deflections of the bushings


233


and the rod


236


are biased in the direction of the release mechanism


220


by a coil spring


242


. The mechanism


219


including wheels


221


, bushings


233


, and rod


236


is so arranged that when the pre-set combination is set by the user, the rod


236


can be deflected by activating the release mechanism


220


. Otherwise, deflection of the rod


236


and activation of the release mechanism


220


is prevented.




In the embodiment shown in

FIGS. 8 and 9

, the release mechanism is activated by depressing the button


223


. As shown most clearly in

FIG. 8

, the bottom surface


243


of cylindrical button


223


contacts one arm of the cam/linkage


244


. (A detail of linkage


244


appears in

FIGS. 10A and 10B

.) The cam/linkage


244


, having a through-hole


245


, rotates about a stationary pin


246


positioned in housing


218


. Cam/linkage


244


also includes a pin


247


which engages both linkage


248


and sliding plate


249


.




Details of linkage


248


and plate


249


appear in

FIGS. 11A

,


11


B,


12


A, and


12


B. Linkage


248


has a through-hole


250


which engages the pin


247


of cam/linkage


244


and a pin


251


which engages through-hole


241


of rod


236


. Pin


247


of cam/linkage


244


also engages slot


252


of plate


249


. Plate


249


slidably engages the internal surfaces


253


,


254


, and


255


of housing


218


(see FIGS.


8


and


9


). Plate


249


also engages stationary pin


256


, which is rigidly mounted to the lower channel


212


, by means of a semi-circular cavity


257


. The leading surface of cavity


257


preferably includes a chamfer


262


to facilitate the sliding of plate


249


along housing surface


255


. Pin


256


passes through housing


218


via circular opening


257


and includes a shoulder


258


which impinges upon the plate


249


if the release mechanism


220


is not activated. Pin


256


preferably also includes a chamfer


259


to facilitate insertion of pin


256


into hole


257


. The position of plate


249


is preferably biased by coil spring


260


mounted on rigid pin


246


so that the plate engages pin


256


when the release mechanism


220


is not activated. Plate


249


also preferably includes a cut-out


261


for receiving the spring


260


(see FIG.


12


A).




According to the present invention, see

FIGS. 8 and 9

, when the preset combination is set on wheels


221


such that rod


236


can axially deflect toward spring


242


when button


223


is depressed, the upper channel


213


can be disengaged from the lower channel


212


so that the first cable end


211


and the second cable end (not shown) can be released. When the button


223


is depressed, the bottom surface


243


of the button impinges upon and deflects cam/linkage


244


. When cam/linkage


244


rotates about pin


246


, pin


247


of cam/linkage


244


deflects linkage


248


via hole


250


in linkage


248


. Linkage


248


via pin


251


deflects rod


236


via hole


241


. Again, rod


236


can deflect since the pre-set combination input to wheels


221


permits the protrusions


237


to align with the slots (not shown) in bushings


233


. At the same time, pin


247


of cam/linkage


244


also engages and deflects plate


249


via slot


252


. This axial deflection of plate


249


away from pin


256


disengages the semi-circular opening


257


of plate


249


from pin


256


such that pin


256


can pass through hole


257


. As a result, locking mechanism


220


and channel


213


can be disengaged from channel


212


.




Another embodiment of the invention, similar to the devices shown in

FIGS. 1 and 2

, is shown in FIG.


13


.

FIG. 13

illustrates an isometric view of the present invention


310


in which some of the device has been removed to clarify the invention. Similar to the device shown in copending U.S. application Ser. No. 09/028,138, the device


310


includes a first u-shaped channel


311


and a second unshaped channel


312


. Channels


311


and


312


may be fabricated from commercially available channels or tubing (for example, a rectangular tube cut in half) or may be fabricated or formed from metal plate, preferably stainless steel plate, by forming or welding or other machining or fabrication processes. The two channels are hinged at


313


such that the second channel


312


can rotate about the hinged end. The width of the second channel


312


is preferably larger than the width of the first channel


311


so that when the second channel


312


is rotated into engagement with the first channel


311


, the second channel


312


covers and conceals the first channel


311


.




The first channel


311


includes means


314


for securing a cable


315


which is similar to the means


14


shown in FIG.


1


. The means


314


includes a set of rigid members or blocks


316


and


317


that are secured to channel


311


, for example, by welding or screws. These blocks


316


,


317


form a wedge-shaped cavity through which the cable


315


passes as it engages means


314


. Means


314


also includes a slidable device


318


(the components of which are more clearly shown in

FIG. 15

) consisting or comprising a rectangular flat plate


319


, a v-shaped wedge piece


320


, and a circular disk


321


. The wedge piece


320


and the disk


321


are attached to the flat plate


319


, and the flat plate


319


slides under the stationary blocks


316


,


317


such that the slidable device


318


slidably engages the slots in blocks


316


,


317


. Plate


319


is also slidably mounted on plate


322


having vertical tabs


323


. Channel


311


also includes opening


346


for passing the cable


315


into the channel so that the cable can be engaged with retaining device


318


and excess cable can pass out of channel


311


.




As shown in

FIG. 14

, the v-shaped wedge piece


320


includes a cavity


324


for accepting a spring


325


and which is depressed by a vertical tab


326


(see FIG.


15


). The wedge piece


320


is shaped similar to blocks


316


,


317


such that the outer surfaces of wedge


320


and the inside surfaces of blocks


316


,


317


act to capture and retain the cable


315


that passes between them. The outer surface of wedge


320


and the inside surfaces of blocks


316


,


317


form an angle of about 30 to 70 degrees with the axis of the channel


311


, preferably an angle of about 40 to 60 degrees. The spring


325


is preferably captured in cavity


324


by the plate


322


.




The disk


321


may be rigidly fixed to plate


319


or it may rotate about a central pin which is fixed to plate


319


. Disk


321


may also have a grove on its perimeter similar to a pulley or sheave to accept and retain the cable


315


.




Plate


322


is connected to channel


312


by means of rods or bars


327


. Bars


327


are preferably pivotably connected to the vertical tabs


323


of plate


322


and pivotably connected to channel


312


at


326


such that when channel


312


is rotated about the pivotable connection


313


, the vertical tab


326


of plate


322


is deflected against the spring


325


. The spring


325


in cavity


324


imposes a load on the v-shaped wedge


320


and deflects slidable device


318


, including plate


319


and disk


321


. This deflection compresses the wedge


320


against the cable


315


such that the cable is wedged between wedge


320


and blocks


316


,


317


. The bars


327


may be one or more rigid rods or bars.




Channel


312


also includes features that are disclosed in copending application Ser. No. 09/028,138 (again, the disclosure of which is included by reference herein). For example, as discussed above with respect to

FIG. 1

, channel


312


includes means


335


for adjustably attaching a cable having a T-shaped end. As shown in copending application Ser. No. 09/028,138, the arms of a T-shaped end of a cable pass through the opening


336


in channel


312


and engage the opposite u-shaped openings


337


in side plates


338


. The tension in the cable (not shown) can be adjusted by appropriately engaging the arms of the T-shaped end in different sets of opposing u-shaped openings


337


(only one set of u-shaped openings is shown in

FIG. 13

due to the view chosen).




Channels


311


and


312


in

FIG. 13

may also includes an elongated slot


39


and perforated vertical tab


40


, as shown in

FIG. 1

, to secure the channels


311


and


312


when rotated into engagement. Channel


312


may also include the cable retainer


42


shown in FIG.


1


.





FIG. 15

shows an exploded view of the components that compose the slidable device


318


shown in FIG.


13


. The wedge-shaped element


320


is rigidly mounted on plate


319


, for example, by welding or threaded fastener, such that the cavity for holding spring


325


is aligned with the slot


331


in plate


319


. The spring


325


is positioned in cavity


324


of wedge


320


. The disk


321


may be fixed, again, for example, by welding or threaded fastener, or rotatably mounted to plate


319


. If the disk


321


is fixed to plate


319


, it may be integral with wedge


320


. If the disk


321


is rotatable it is preferably rotates about a rigid pin


332


mounted to plate


319


, for example, in hole


333


. The assembly comprising wedge


320


, spring


325


, disk


321


, pin


332


, and plate


319


is slidably mounted on plate


322


such that tab


326


passed through slot


331


and into cavity


324


and impinges against spring


325


.




Though not shown in these figures, the device shown in

FIG. 13

may also include combination lock mechanisms shown and described earlier in

FIGS. 7 through 9

and the mechanisms shown and described below in

FIGS. 16 through 23

.




Another combination lock mechanism that can be used, for example, to secure channels


11


and


12


of

FIG. 1

or channels


311


and


312


of

FIG. 13

is shown in

FIG. 16

,


17


and


18


.

FIG. 16

illustrates a plan view of a combination-type locking mechanism


410


that can be mounted to the top of channel


12


of

FIG. 1

or channel


312


of

FIG. 13

to securely retain the two channels and prevent unauthorized release of the cable the channels retain. This locking mechanism can also be used for the device disclosed in co-pending application Ser. No. 09/028,138 (again, the disclosure of which is incorporated by reference herein). Part of the device housing of mechanism


410


is removed to facilitate the following discussion.




Locking mechanism


410


includes a housing


411


, a release mechanism


412


and a combination lock mechanism


413


. The release mechanism


412


engages and disengages, as desired, a through hole of threaded, nut-like device


450


(similar to threaded device


50


shown in

FIG. 6

) that rotatably mounts to a threaded pin in the lower channel. For example, device


450


can be threaded onto a rigid threaded pin mounted channel


11


in

FIG. 1

or channel


311


in

FIG. 13

, or most preferably to a threaded pin in the lower channel disclosed in co-pending application Ser. No. 09/028,138. The features of the threaded device


450


are most clearly illustrated in FIG.


19


. The vertical extension of device


450


passes through a slotted hole in housing


414


to engage the release mechanism


412


.




The release mechanism


412


comprises a uniquely designed pivoted lever


415


. This lever


415


, more clearly illustrated in

FIGS. 21 and 22

, pivots about pin


416


which is rigidly mounted in housing


411


. Lever


415


includes a push button end


417


and a engagement end


418


. The engagement end


418


of lever


415


engages pin


419


which engages the through hole


451


(see

FIG. 19

) of threaded device


450


. Pin


419


is biased into engagement with device


450


by means of spring


420


, preferably a coil spring mounted on a pin (not shown). The engagement end


418


of lever


415


also engages lever arm


421


of locking mechanism


413


. (Lever arm


421


is most clearly shown in

FIG. 23.

) In the locked mode of locking mechanism


413


, the lever arm


421


prevents the lever


415


from deflecting.




The relationship between lever arm


421


and lever


415


us more clearly illustrated in FIG.


17


. As shown, when the arm


421


is in the downward “locked” position, the arm


421


engages the engagement end of lever


415


and prevents the deflection of arm


415


. In the upward “unlocked” position of arm


421


, shown in phantom in

FIG. 17

, the engagement end


418


of lever


415


does not engage arm


421


and the lever


415


is allowed to deflected when the push button end of lever


415


is deflected. When the combination mechanism is locked and the arm


421


is in the down position, the lever


415


cannot deflect and the pin


419


cannot disengage from the through hole


451


of threaded device


450


and the channels, for example, channels


11


and


12


of

FIG. 1

, cannot be disengaged.




As shown in

FIG. 17

, the device


410


may also include a cable retaining plate


442


similar to retainer


42


shown in FIG.


1


.





FIGS. 19 through 23

illustrate the general features of the components of the device shown in

FIGS. 16 through 18

.

FIG. 19

illustrates a typical threaded, nut-like device


450


having a through hole


451


for engaging pin


419


. Device


450


includes a threaded hub


452


which can thread upon a rigid pin (not shown) mounted in the lower channel of the devices described earlier. The device shown is fabricated from flat plate, but any suitable design which provides the desired function may be used.





FIG. 20

illustrates an isometric view of the pin


419


. Pin


419


typically includes a step


425


which engages the engagement end of lever


415


. Pin


419


also preferably includes a blind hole


426


into which coil spring


420


may be inserted and retained. Though pin


419


is shown rectangular in cross section, it may also be round.





FIGS. 21 and 22

are front and rear isometric views of the lever


415


. Again, the lever


415


includes a push button end


417


and an engagement end


418


. Lever


415


also includes a through hole


427


which engages pin


416


(see FIG.


16


).





FIG. 23

illustrates an isometric view of the combination lock mechanism


413


shown in FIG.


16


. In the embodiment shown, the lock mechanism


413


includes three rotatable combination wheels


428


mounted on a pin


430


and having peripheries bearing human readable indicia, that is, numbers or letters. Attached to each wheel and rotating with each wheel is a hub or cam


429


. Each cam is general circular in shape but includes a flat land area


431


. The surface of the cams


429


bear against the fingers


432


of the lever


433


. Lever


433


is pivotably mounted at the end


434


of the fingers


432


. The lever


433


and lever arm


421


are biased to the upward position by a spring not shown. When the combination wheels


428


are in the “locked” position, the rounded surfaces of the cams


429


bear against the fingers


432


and deflect the lever


433


about the ends


434


. This deflects the lever arm


421


to the down position and, as shown in

FIG. 17

, prevents the deflection of lever


415


and the channels cannot be disengaged. In

FIG. 23

, the locking mechanism is shown in the “unlocked” when a predetermined combination is set on the combination wheels


428


such that the flat cam areas


431


bear against the fingers


432


. This permits the deflection of lever


433


under the force of the spring (not shown) to deflect upward and, as shown in

FIG. 17

, disengage the lever


315


so that when the button end


417


of lever


415


is depressed the pin


419


can be disengaged from device


450


and the channels can be separated and the cable released.




As described above, the methods and devices of this invention provide means for securing the ends of one or more cables, for example, to prevent, the theft or unauthorized use of one or more pleasure craft while facilitating the act of securing and releasing the craft.
