Description




This invention relates to security devices, and more particularly to security locks for use on devices such as skateboards, snowboards, snow skis, and the like.




BACKGROUND OF THE INVENTION




Skateboarding, snowboarding and snow skiing are all extremely popular sports today. It has been reported that skateboarding ranks in sixth place in popularity in all sports and is one of the fastest growing sports today. One out of every ten teenagers owns or rides a skateboard. Skateboarding is increasing globally both as a competitive sport, and as a mode of transportation for today's youth. There are primarily two types or styles of skateboards, namely a short one used for high performance such as tricks, competition, and exhibitions, and longboards used for downhill competitions as well as transportation to school, the beach, and neighborhood activities. Today, skateboards often replace bicycles as the preferred mode of transportation.




Like skateboarding, snowboarding is one of the fastest growing sports today. One out of every four persons who regularly visits ski resorts owns or rides a snowboard. Snowboarding is increasing globally both as a competitive sport as well as an alternative to conventional skiing. Snow skiing is still the most popular winter time sport in the world today.




These types of equipment are relatively expensive. For example, skateboards are an expensive investment, particularly for young people, ranging from around $100 to $300 each. Currently, skateboarders have to carry their boards while walking through a mall, at school or bury it in the sand at the beach so as to prevent theft.




As to snowboarding and snow skiing, whether a person uses one or the other, the need for protecting the equipment in today's increasingly crowded ski resorts is a must. As more and more people turn to snowboarding and skiing, the risk of theft is a growing concern.




Some people make use of steel cables with locks which can be used to secure any of these types of equipment to some fixed object such as a secure pole. Unfortunately, these types of cable-lock devices must be carried by the person using the sporting equipment; for example, a skateboarder traveling to the beach to surf has to physically carry the locking device, which tends to be bulky.




Ski resorts frequently have racks for skis, but which normally are not provided with any type of locking system, and such resorts generally have not yet addressed some type of rack for snowboards. As more and more people turn to these sports, the risk of theft is a growing concern.




Therefore, there is a need for a reliable locking device. Some forms of locking devices have been devised as is evidenced by U.S. Pat. No. 4,773,239, No. 5,179,847, No. 5,177,986, No. 5,706,680. However, these devices either involve locking devices that must be carried on the person while the sporting equipment is in use, such as a separable lock device, or they involve relatively bulky or complicated devices.




A suitable locking device would allow the skateboard rider protection against theft. The present locking devices offer the skateboarder the opportunity for protection currently only available to bicyclists and motorists.




Accordingly, it is a principal object of the present invention to provide a relatively simple locking device or system for sports equipment like skateboards, snowboards, snow skis, and the like.




A further object of the present invention is to provide a locking device for sports equipment, such as skateboards, snowboards, snow skis, and the like which does not require the person to carry a lock, cable or other separate locking device.




A further object of the present invention is to provide an improved security device for sports equipment.




The locking devices of the present invention will help deter a would-be thief from stealing skateboards, snowboards, snow skis, and the like while the rider eats lunch, goes to the lodge, car, beach or any other situation would involve leaving their equipment behind for any length of time. The present locking concepts can provide the skateboarder, snowboarder and skier extra peace of mind by knowing their equipment is secure.

SUMMARY OF THE INVENTION




According to the present invention, a relatively simple and compact locking device is provided for skateboards, snowboards, snow skis, and the like. In one embodiment, the device comprises a compact and self-contained cable lock which can be mounted to the truck of a skateboard, boot bracket attachment of a snowboard, or binding of a snow ski so as to be securely affixed to the sports item. A lock can include a releasable cable which normally is retracted into the locking device, but which can be extended to lock around a fixed pole or other fixed or stationary object so as to secure the sporting item thereto. Other embodiments have different forms of cable lock assemblies. In another embodiment, a relatively simple bracket is provided which can be securely attached, for example, between the wheel truck and skateboard body, and be used with a cable and lock for securing the sporting item when desired.




DETAILED DESCRIPTION




Turning now to the drawings, and first to

FIG. 1

, a portion of one end of the bottom of a skateboard


10


is shown and which has a conventional wheel truck


12


with a truck base


14


and wheels


15


and


16


, it being understood that the skateboard has a similar wheel assembly at the other end thereof (not shown in

FIG. 1

, but see

FIG. 5A

) as is conventional. The wheel truck base


14


has several holes through which the same is attached to the underside of the skateboard


10


by bolts and nuts


18


in a conventional manner.




According to a first embodiment of the present invention, a combination lock assembly


20


is affixed to the skateboard, preferably beneath the wheel truck


14


, and includes an extensible cable


22


which can be uncoiled or released so that it can be attached around a secure object, such as a fixed lamp-post, bicycle rack, or the like. The combination lock assembly


20


includes a combination lock


24


having the cable


22


affixed within the lock


24


at one end (not seen) and being releasable at a second end


26


by depressing a lock release button


28


. A recoil button


30


is provided which, when depressed, recoils the cable


22


back into the lock


24


. The lock


24


further includes rotatable number wheels


32


via which the lock combination can be set. This form of combination lock


24


having a cable


22


, lock release button


28


, cable release button


30


and wheels


32


, is essentially a conventional product. The combination lock


24


is affixed in any suitable manner, as by bolting or riveting to a sheet metal tab


36


or extrusion. The sheet metal tab or extrusion


36


is adapted to be affixed to the bottom of the skateboard underneath the wheel truck


14


via the bolts and nuts


18


. The tab


36


has suitable holes which mate with the holes in the wheel truck


14


to allow this mounting arrangement. The bolts and nuts


18


can be further secured by using a liquid locking agent such as Loctite, or secured in any other suitable manner, so as to minimize the chance of disassembly of the lock assembly


20


from the truck


14


and board


10


. A suitable decorative cover


38


having an end cap


39


can be provided as part of the lock assembly


20


.




In use, the skateboarder merely sets the appropriate combination on the wheels


32


of the lock and depresses the lock release button


28


which allows the cable


22


to be detached at end


26


. A length of the cable can then be pulled out of the lock


24


and wrapped around a secure object such as a lamp post or other device, and the end


26


reinserted into the lock


24


and the wheels


32


changed to thereby secure cable


22


in the lock


24


, and thus secure the skateboard to the fixed object. The present arrangement is relatively compact and lightweight and does not interfere with or impede the operation of the skateboard


10


, while still providing protection against theft. The combination lock can be replaced by a key lock if desired. However, the combination lock is preferred since the user does not have to keep, and keep track of, a key.




As is known to those skilled in the art, skateboards like skateboard


10


are quite flexible, and, thus, it is important that an item like the lock assembly


20


be formed of a material which also is somewhat flexible so as not to impede the flexibility of the board. Any suitable material can be used including aluminum, super tough nylon, and the like. It is also important that the assembly


20


be formed of a material which can withstand the impact when skidded on a hard or rough surface, such as a curb. The end cap


39


at the forward end of the assembly is suitably configured to minimize the chance of the lock assembly


20


catching on any item during use of the skateboard. Further, it is important that any structure added at or near the wheel truck


14


and wheels


15


and


16


not interfere with the flexing of the same and do not present any drag points to the wheels themselves.




A second embodiment is illustrated in

FIGS. 2A and 2B

, and is similar to the embodiment of

FIG. 1

in that a lock assembly is adapted to be mounted under the wheel of truck


14


(not shown in FIGS.


2


A and


2


B), but has a different form of combination lock arrangement.




In this embodiment, the combination lock assembly


46


includes an extrusion


48


forming a base plate which is disposed underneath the wheel truck


14


(not shown in

FIG. 2

) to the skateboard


10


(not shown in FIGS.


2


A and


2


B). The base plate


48


includes as an integral part a tubular side section


54


to which an end of a cable


52


is secured. The base plate


48


has suitable mounting holes


48




a


to allow the same to be secured to the skateboard via the mounting bolts for the truck


14


. The lock assembly


46


further includes the steel cable


52


, preferably plastic coated and permanently affixed, as by swaging for example, to the tubular side section


54


. The base plate


48


extrusion also includes an upstanding bracket


62


. Thus, the first end of the cable


52


is secured in the section


54


, and the second end is hingeably connected by a steel pin


56


to a removable end


58




a


of a conventional combination lock


58


. A second end


58




b


of the combination lock


58


is secured via another steel pin


60


to the bracket


62


. The combination lock


58


has a plurality of wheels


64


which can be rotated to set the combination and to allow the same to be opened at the end


58




a


to thereby enable the cable


52


to be released and then wrapped around a fixed object in a manner like the cable


22


of FIG.


1


.




The combination lock assembly


46


further includes a cable retainer member or plate


66


attached to the board forward of the extrusion


48


, and has a flanged forward section


68


for normally retaining the cable


52


underneath the flange


68


as seen in

FIG. 2



a.


This arrangement helps prevent the cable from catching on objects while the skateboard is in use, but allows the cable to be pulled out from under the flange


68


when the combination lock


58


is released by setting the selected combination. The embodiment of

FIG. 2A

further preferably includes a molded plastic skid plate


70


, suitably spaced from the flange


68


by a spacer tab


72


to provide room for the insertion and removal of the cable


52


under the flange


68


. This skid plate


70


is disposed toward the forward end of the overall combination lock assembly and helps in preventing the assembly


46


from catching on objects when the skateboard is in use.




As was the case for the embodiment of

FIG. 1

, it is important that the lock assembly of

FIGS. 2A and 2B

be sufficiently flexible and designed so as not to impede flexibility of the associated skateboard. Preferably the retainer member


66


and skid plate


70


are formed of suitably strong but yet flexible material, such as super tough nylon, so as to be somewhat flexible and also withstand impact and abrasion. In the embodiment of

FIGS. 2A and 2B

, the member


66


is secured at its forward end


49


with suitable screws (not shown) mounted through screw holes


50




a.


Because of the flexing characteristics of the board, rearward screw holes


50




b


preferably are elongated, and the rear end of the member


66


is in the form of a tab and is not fastened to the board by screws but, instead, the rearwardly extending tab


67


fits within a slot


48




b


in the extrusion


48


to be disposed underneath the wheel truck base


14


. This arrangement allows the retainer member


66


to be retained against the bottom of the skateboard (not shown in FIG.


2


B), but allows some movement of the retainer member


66


forward and backwards with respect to the extrusion


48


to minimize impeding flexibility of the board.




A further embodiment is shown in

FIG. 3

, and like reference numerals are used for items which are the same as in

FIG. 1

, namely a skateboard


10


, truck


12


, truck base


14


, wheels


15


,


16


and mounting nuts and bolts


18


. This embodiment differs in that the lock assembly


70


is entirely removable from the board


10


. The assembly


70


comprises a combination lock


72


and cable


74


having an end


75


which releases from the lock


72


so that the cable


74


can be threaded through open barrels


76


,


77


of an extrusion


78


, preferably a machined aluminum extrusion and which is shown in greater detail in

FIGS. 4A and 4C

. The cable


74


can be released when the combination is set and a cable release


72




a


is depressed. A molded plastic skid plate


80


serves both as a skid plate and a cover or retainer for the combination lock


72


. As will be apparent, the extrusion


78


is mounted underneath the truck base


14


. The skid plate


80


includes a plurality of holes


84


to allow the same to be retained on the board by suitable wood screws.




This arrangement allows the lock assembly


70


to either be mounted as shown in

FIG. 3

or, alternatively, the lock assembly


70


can be removed from the board and carried around the neck of the skateboarder if desired.

FIG. 5A

shows an example of how the assembly


70


can be secured to the board extrusion. The relatively wide barrel sections


76


and


77


are relatively difficult to cut in the case of an attempted theft. Preferably, one of the barrel sections, such as section


77


as best seen in

FIG. 4A

is of a shorter length so as to allow the shackle of a typical padlock to fit within the opening therein if desired. A further alternative for allowing the use of conventional padlocks is shown in FIG.


5


B and will be discussed subsequently.




Turning now to

FIGS. 5A and 5B

, the same illustrate a modification of the embodiment of

FIGS. 3 and 4

wherein an extrusion


88


similar to the extrusion


78


of

FIG. 3

has side barrel sections


86


and


87


with at least one drilled hole


87




a


(note

FIG. 5B

) to more readily allow a short shackle


90


of a lock


91


to be locked to the extrusion


88


so as to enable a cable


92


to be locked about any suitable fixed object for security purposes. This

FIG. 5A

also illustrates how the lock assembly


70


can be fed through one of the barrels


86


for locking the board to a fixed object for security purposes.




When an item such as the extrusions


78


(FIG.


3


),


88


(

FIG. 5A

) or plate or extrusion


36


and


48


(

FIGS. 1 and 2

) are added underneath one of the truck bases


14


of the skateboard, it is desirable to shim the second truck base


14




a


at the other end of the board with a spacer plate


94


as illustrated in

FIG. 5A

so as to provide an equal spacing of the truck


14


a on the board like the spacing of the truck


14


caused by the addition of the extrusion or plate.




Turning now to

FIG. 6

, another embodiment is shown which is substantially identical to that of

FIG. 1

, but in this case for a snowboard


96


. The combination lock assembly


20


is identical to that shown in

FIG. 1

, and includes the tab


36


which can be attached to the top of the board


96


via the snowboard boot bracket


97


. The boot bracket


97


is conventional, except to the extent it or the tab


36


may need to be modified to fit the tab


36


underneath the boot bracket.




A still further embodiment is illustrated in

FIG. 7

, and in this case a lock assembly


100




a


-


100




b


is provided for a pair of snow skis


102




a


-


102




b


having typical bindings


104




a


-


104




b


with respective bases


106




a


-


106




b


for attachment to the skis.




The lock assemblies


100




a


and


100




b


in this embodiment may comprise a pair of assemblies


100




a


and


100




b


forming a two-part design so as to provide equal weight on both skis


102




a


-


102




b


, although a single combination lock assembly could be used (similar to that shown in

FIGS. 1 and 6

) if desired. Each assembly


100




a


and


100




b


includes an elongated sheet metal plate


110




a


-


110




b


which is secured under the binding plates


106




a


-


106




b


to the respective skis


102




a


-


102




b.


One of the two assemblies


100




a


-


100




b


includes a combination or key lock, and in the embodiment illustrated in

FIG. 7

the assembly


100




a


is shown with a combination lock


114


with an opening


115


for an end


116


of a cable


117


which, in turn, is fixed at


118


to the second lock assembly


100




b.


The lock assembly can include a recoil assembly in assembly


100




b


so as to allow the cable


117


to be fully retracted within assembly


100




b


when not in use. A recoil button


120


is provided for this purpose.




As an alternative to the combination lock


114


, the lock assembly


100




a


can be a key lock. In this case, the forward end


124


of assembly


100




a


can be formed of flexible material, such as plastic or rubber, with a slit


125


to allow the end


126


to be pulled forwardly so as to uncover a key slot hole. This flexible end


126


arrangement allows the key slot hole to be covered while the skis are in use so as to prevent or minimize snow or other material entering the key slot hole.




A further lock arrangement is illustrated in FIG.


8


and comprises a cable coil assembly


130


housing a coil of cable


132


. The assembly


130


includes a plurality of apertures


134


to allow the same to be mounted beneath the truck base


14


(not shown in FIG.


6


). Preferably, the cable


132


retracts under spring pressure within the assembly


130


.





FIG. 9

illustrates still another, and simpler arrangement for locking sports equipment, particularly skateboards. This device does not include its own built in lock (not shown but of the type used to lock bicycles) or cable assembly as in the other embodiments, but comprises a metal bracket


142


configured to fit, for example, under the truck base


14


(

FIG. 1

) and to provide inclined ribs


144


,


146


with respective holes


144




a


,


146




a


for receiving a separate cable and lock which the skateboarder can carry in a pocket or the like. This assembly provides a very simple and inexpensive device which can be mounted between the truck base


14


and bottom of the skateboard


10


(

FIG. 1

) via mounting holes


148


. An upstanding tab


150


can be integrally formed, and can have a recessed area


152


for a label containing a logo, instructions for use, or the like. The bracket


142


typically can be formed of 0.093 inch thickness 50/52 aluminum, with an anodized finish, which has been found to be of suitable structural integrity for use as a locking bracket.




While embodiments of the present invention have been shown and described, various modifications may be made without departing from the scope of the present invention, and all such modifications and equivalents are intended to be covered.
