1. Field of Invention
The present invention lies in the domain of bicycle security and utility locks, and generally relates to a locking device for a bicycle and more particularly to a locking device which is adapted to contain a plurality of U-shaped locks, or alternate shaped locks, along with an effective mounting means and several other supplementing elements.
2. Prior Art
There has been a large amount of activity in the general field of bicycles and utility locks placed on them, specifically for securing a bicycle when it is not in use. The prior art discloses numerous types of utility locks and/or locking devices. At present the commonly known bicycle security locks or locking devices primarily fall in the category of U-shaped locks, cable, and chain and pad lock devices. Besides these, there are also several known locking devices which use various other encircling components as means for securing a bicycle and aimed at theft prevention, such as cuff locks, as well as hinged locks that are circular, oval, and square relatives to the U-lock.
Despite the activity in the fields of utility locks and bicycle security, no prior art was found directly relating to the connecting of two rigid locks when stored and/or not in use. In fact, although there are some limited combinations of U-locks and chain or cable locks available for purchase, there has not been any patent activity in this particular field, relating to the connecting of two or more locks. As a result of this lack of activity many of the prior art locks described below are noteworthy, but not sufficiently adequate for comparison.
U-Locks—One of the more secure and popular bicycle lock designs that is currently available commercially is a U-shaped lock comprised of a U-shaped shackle with a cross bar that houses the locking mechanism. Some bicycle locks, based on this design, are secure and effective enough that the manufacturing company provides financial protection against theft. Some U-Shaped Locks made available under the trademark KRYPTONITE® provide such financial protection, (as recently as January 2005, Kryptonite®'s ‘KryptoLok’, provided $1250 (USD) Anti-Theft Protection available in the USA and Canada). Although these U-Shaped Lock designs, primarily based on U.S. Pat. No. 3,924,426, (Zane, et al., December 1975); U.S. Pat. No. 3,967,475, (Zane, July 1976); and U.S. Pat. No. 4,155,231, (Zane, et al., May 1979), are effective deterrents to theft, these locks are limited by their dimensions. U-Shaped Locks are limited in their size due to the need of keeping them difficult to break, as well as both convenient, and portable.
Another inconvenience arises with U-locks, and other similar locks, when the fixed, stationary post or other secure object that the bicycle is being secured to is thick enough that the front wheel, (or other item that is desirable to secure), does not fit into the lock along with the frame of the bicycle and the rear wheel. Even when there is room to secure the frame and both wheels, it would be necessary to remove the front wheel so that it can be locked alongside of the frame, back wheel, and stationary component/rack that the bicycle is being secured to. Furthermore, these locks can only secure a bicycle at one fixed point, whereas adding a second lock can double this, increase the protection provided, and deter the likeliness of theft.
In order to improve security and reduce the need to remove the front wheel to lock it, manufacturers both recommend, and provide for retail purchase, a combination of both U-Shaped Locks and chain or cable locks sold together. This combination provides users with the opportunity to lock components and accessories that do not fit conveniently within a single U-Shaped Lock. Examples of this can be seen with On Guard® Locks' Bulldog DT5012 or PitbullDT5005, both are sold as combinations of a U-shaped lock and a cable lock. However, storage of the cable lock may be inconvenient, cumbersome, or time consuming (to ravel/unravel and secure to the U-lock), and the security of a cable or chain lock is often easier for thieves to compromise compared to a U-Shaped Lock. Some chain locks such as On Guard®'s Mastiff™ Series may be more difficult to compromise compared to U-Shaped and similar shaped locks, but these chains tend to be significantly bulkier, heavier and less convenient. Often these secondary locks, such as chain and cable locks, used in addition to a U-shaped lock, are stored in panniers or backpacks making them more cumbersome/difficult to carry, or these locks are secured at one location, making them effective only when returning to this location.
Alternate Shaped Locks—Although not specifically a U-Shaped Lock, the Bike Guard®'s ‘Lock Jaw’ designed oval-shaped locks are noteworthy alternatives. Bike Guard®'s Jaw Ultra, as well as the Lock Jaw 2000, and the Lock Jaw 1200, are hinged locks that serve the same function of U-shaped locks. Also serving similar functions to the U-lock, but with a single hinged component rather than two individual components are ring-styled Bike Guard® Bonelocks which are hinged and round, and the Ultra Bike Club™ by The Club®, which is shaped like a rectangle with rounded edges. Each of these hinged locks share the same shortcomings of the previously described U-locks, being limited in space, requiring the removal of the front wheel to be secured with other components, and suggesting the need for a second lock.
Some locks have different, more novel shapes. The Piano Shaped lock, U.S. Design Pat. No. D392,540, (McDaid, March 1999) is unique in design but would be awkward to use, with little if any functional benefit being gained from the different shape. Cuff style locks such as US Pat No. 20020108406, (Makos, et al., August 2002) can lock a bicycle component such that minimal space is left unused within the lock, but these locks are limited in how much they can fit it them. Due to a lack of size, these locks, such as Cuff Locks sold by Master Lock®, have limited capability to add components, such as a removed front wheel, into the secured space of the lock. Therefore, these locks would serve more conveniently as a secondary supporting lock rather than a primary bicycle lock.
Locking Mechanisms and Shackle Feet—Conventional locks and locking mechanisms are necessary components of utility locks. The location of the lock and locking mechanism can vary on prior art U-locks. U.S. Pat. No. 5,406,812, (Jaw, April 1995) places the locking mechanism on one end of the locks' crossbar. This lock has two straight feet for the U-shaped shackle that are secured within the aligned openings of the cross bar, a common design with U-locks. U.S. Pat. No. 5,257,517, (Dale, November 1993) also has the locking mechanism on one end of the locks' crossbar, but with a large reinforcing shield that begins at the locking case and continues along the cross bar to encase the nearest aligned opening on the lock's cross bar. U.S. Pat. No. 5,092,142, (Zane et al., March 1992), which has one straight foot and one bent foot on the U-shaped shackle, places the locking mechanism on the opposite side of the aligned openings on the cross bar, (between the aligned openings and closer to one opening than the other). The locking mechanism is placed closer to the aligned opening that receives the straight foot to secure this end of the shackle, while the second foot is secured by the bend after it is received in the other aligned opening. Yet another lock, U.S. Pat. No. 5,787,736, (Ling, August 1998) places the locking mechanism in the center of the cross bar, on the opposite side of the aligned openings, and has the added feature of a combination lock instead of a key entry. Each of the locks described above, despite their unique attributes, share the same limiting challenge of size and efficiency, that U-locks do, limiting their ability to secure all necessary components on a bicycle.
Self Locking and Push Locks—Some locks are easier to close or secure than others. Self-locking U-Locks such as the ABUS® Manhattan Lock would be functionally easy to close, just as a push lock such as the ABUS® Granit Plus 51 Lock would be. Push locks, some of which are based on U.S. Pat. No. 5,133,203, (Huang, July 1992) and U.S. Pat. No. 5,195,340, (Huang, March 1993), like self-locking locks, are easy to lock. Because push locks only need to have the inner ‘push rod’ pushed in to lock them, there is no need to worry about using the key to lock the locks, thus, like self-locking locks (see Hsieh below), you are free to use your hands to concentrate on fitting or resting the locks together as required. Like push locks, U.S. Pat. No. 5,488,845, (Hsieh, March 1994) which locks automatically aided by coil springs that engage when the key is turned to the unlock position, would also prove to be easy to use. However, the efficiency of push and self locking locks does not compensate for the shortcomings of the U-locks the are place on, (as already explained).
Lock Holders—Two prior art bicycle lock holders, U.S. Pat. No. 4,736,921, (Zane, et al., April 1988), or the EZ Mount Bracket, by Kryptonite®, based on U.S. Pat. No. 6,422,442, (McDaid, et al., July 2002), are effective at holding a lock to a bicycle frame. However these lock holders, and other lock holders patented or available for purchase, are only capable of securing one lock to the frame of the bicycle and require a second lock holder if a second lock is wanted or needed. A second lock holder on a bicycle, using any of the current lock holders on the market, requires significantly more space to be used on a bicycle for securing the second lock, than storing just one lock.
3. Objects and Advantages
This invention relates generally to bicycle and utility locks, and pertains, more specifically, to an improvement on existing locks whereby locks are connected and stored together when not in use. Although described primarily as U-shape locks, the locks used in this invention may take on many different, alternate shapes. In fact all rigid locks, used for securing (primarily) bicycles, found in prior art searches could be used as one or more of the connected locks as described in this invention.
Advantages Over Prior Art—All of the prior art locks described above can be used in conjunction with this invention, whereby this invention can be used to connect two or more already invented prior art locks, or a prior art lock to a newly designed lock. More than one prior art lock can be securely connected together within the confines of a space not bigger than, or not significantly bigger than, storing one lock, until the locks are needed at which time these locks are fully separable.
In view of the foregoing disadvantages inherent in the above mentioned prior art, the general purpose of the present invention is to provide an improved combination of convenience and utility, to include all the advantages of the existing prior art, and to overcome the above mentioned disadvantages/drawbacks of the prior art.
The present invention relates to a new lock securing device in which there exists a plurality of locks aimed at enhanced bicycle security. Storage of one lock connected within the confines of, or placed adjacent to, a second lock is accomplished at a single place when the lock(s) are not being used to secure the item(s) they were purchased to secure. The convenience of storing two or more successive locks in this fashion is useful when the locks are stored on a bicycle, moped, scooter, motor cycle or other valuable possession where the security of locking such items is necessary, the convenience of a second lock or successive lock(s) is desirable, and storage space may be limited. A second lock stored in one of the ways suggested in this invention creates an advantage over prior art locks in that this invention gains the benefit of a second lock to secure more items such as a front wheel, (without having to remove it from the bicycle), as well as securing the bicycle to a stationary item(s) a second time; while requiring little if any additional space for storage on a bicycle.
When the locks of the present invention are separated, they work independently of each other and can be used to greatly increase the security, the convenience and the volume or number of items being secured.
Key Advantages—Bicycle commuters would find this invention most advantageous. Although these advantages benefit all bicycle users with their bicycle security, commuters have some common challenges that, when combined, make them ideal candidates to take full advantage of this invention. Bicycle commuters would benefit greatly since they:
a) Leave their bicycles unattended in public places, often with great risk of theft, so a second lock would act as a significant theft deterrent.
b) Take the time to remove their quick-release front wheel from their bicycle in order to secure it within the confines of their lock, along with using this same lock to secure their rear wheel, and bicycle frame, to a bicycle rack or another immobile stationary object. A second lock saves time and energy by reducing the need to remove the front wheel from the bicycle to secure it. Furthermore, commuters that have a front wheel that is bolted on rather than quick-release still tend to secure this wheel with a second lock.
c) Are more concerned with scurity since they depend on their bicycle as a key means of transportation. For this reason commuters are more likely to want to carry a second lock with them, and will often end up carrying a second lock in a backpack or pannier, using up storage space unnecessarily.
d) Would find it easier to carry and use two rigid locks, rather than carrying a cable or chain lock as a secondary means of securing their bicycle. Many commuters choose a chain or cable lock for their second lock since space on a bicycle is at a premium.
e) Use much of the existing space on the bicycle to place a water bottle, bicycle pump, panniers etc. thus reducing the availability of space on a bicycle to place a second lock. So, adding a second lock within the confines of, or adjacent to, the first lock provides them with added security without requiring more space on the bicycle.
f) Are more likely to have other items that they may wish to secure on a bicycle. Commuters would use the added space of a second lock to store other items with their bike such as a helmet, a second traveler's bicycle (such as a child's), a backpack or pannier, or a quick-release seat.
g) Are more likely to use their lock properly, and are aware of the value of having a second lock, stored effectively and efficiently on their bicycle. Many bicycle users use a lock improperly locking only their frame, and exposing wheels and other components to theft. Commuters are savvy about protecting their bicycle and would recognize the value of using this invention to protect their personal property.
Other advantages are noted in the ‘Conclusion, Ramifications and Scope’ section. Eight challenges are recognized in addition to the advantages of this invention that alleviate these challenges.
Key Objects—The principle object of the present invention is to provide a locking device wherein, the enhanced and better security is achieved by a plurality of locks, which when put to use immobilizes the secured bicycle and/or bicycle components at several places.
Another objective of the present invention is to provide a locking device, wherein the plurality of locks can be stored adjacent to, or within the confines of, a single lock, thus optimizing on the aspect of storage at single place, when the locks are not put to use.
Yet another objective of the present invention is to provide a locking device, which remains attached to the bicycle at all times. The present invention has been conceptualized with a further objective of providing more than one locking device, which can be regarded as an integral part of the bicycle. This is advantageous compared to storing a second lock in a pannier, backpack, gym bag, or otherwise away from the bicycle.
Yet another objective of the present invention is to provide a locking device which can be regarded as an integral part of a bicycle's inherent security.
These together with other objects of the invention along with the various features of novelty that characterize the invention are pointed out with particularity, in the claims annexed hereto and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its user, reference should be made to the accompanying drawings and descriptive matter in which these are illustrated exemplary embodiments of the invention.
This invention pertains primarily to a U-Shaped Lock, but also ring-styled locks, oval-shaped, and square-shaped locks, and other locks, including handcuff locks and anchor locks, used to secure bicycles and other recreational vehicles. One or more rigid locks, or a lock holder, or an independent sleeve, are modified so that at least one more lock is secured conveniently to it, or next to it. The advantage of storing more than one lock this way is particularly convenient on a bicycle where storage space is limited.
To achieve the advantage of having more than one lock connected together in a limited space, while stored on a bicycle, the locks may be:
A) Connected with one lock stored within the confines of a second lock, when these locks are not being used to secure the item(s) they were purchased to secure;
B) Stored connected by means of an additional component and/or lock holder;
C) Stored side-by-side, either attached to each other, and/or mutually attached to an additional component, or lock holder.
The convenience of storing two locks in one of these fashions is useful when such locks are stored on a bicycle, moped, motor scooter, motorcycle or other valuable possession, where the security of locking such items is necessary, the convenience of a second lock is desirable, and storage space may be limited. When separated both locks work independently of each other and can be used to greatly increase the security, the convenience and the volume or number of items being secured.
In the drawings, closely related figures have the same number but different alphabetic suffixes.
21 Inner U-Shaped Lock—This component is comprised of two main parts that fit together; the Inner Cross Bar 23 and the Inner U-Shaped Shackle 22. This lock is named the Inner Lock since it is the lock that is usually, (though not necessarily), connected inside a second lock, the Outer U-Shaped Lock 26, when the two locks are fastened together. Other components may or may not be present as required by the specific variation of this invention being described. These added components include, but are not limited to, Sleeves 24, Tabs 25, Tongues 34, Grooves 36 and Rings 40 which would be features added to the Cross Bar 23 and/or U-Shaped Shackle 22 as needed in order to meet the need of connecting the two locks together securely, and conveniently, when the locks are not in use. Note that there may be more than one Inner Lock present in some variations of this invention, (see
22 Inner U-Shaped Shackle—The Inner U-Shaped Shackle 22 is fastened together with the Inner U-Shaped Lock's Cross Bar 23 by means of ‘feet’ (see 38 and 39) that fit into, and are secured within, the Inner Aligned Openings 32 on the Cross Bar 23 of the Inner U-Shaped Lock 21.
The U-Shaped Shackle component is what gives the “U-Shaped Lock” its' name. It is one of two major components that the Inner and Outer U-Shaped Locks 21 and 26 are comprised of. There are a lot of conventional designs that suggest different sizes, and shapes for this part of the lock. Most conventional designs suggest that it is a rigid bar that has two parallel legs of equal length that are connected by a U-shaped curve in the bar. This invention will work with these conventional designs and other designs that are less conventional. Where this invention varies from other designs is with regards to the components that are added to either the U-Shaped Shackle(s) 22 and 26, and/or the U-Shaped Lock's Cross Bar(s) 23 and 28, and/or additional components (described in detail herein), in order to meet the need of connecting the two, or more, locks together securely, and conveniently, when the locks are not in use. See also, Outer U-Shaped Shackle 27, on an Outer U-Shaped Lock 26 (both described below).
23 Inner Cross Bar—This component and the Inner U-Shaped Shackle 22 make up the two essential components of the Inner U-Shaped Lock 21. The Inner Cross Bar 23 holds the two Aligned Openings 32 and the Lock Case and Locking Mechanism 29 needed to secure the Inner U-Shaped Lock's U-Shaped Shackle 22 to it.
24 Sleeve—Sleeves are hollow openings used primarily to secure a component of one lock to a component of another lock. Sleeves can also be described as either tubes or rings, (note Ridged Rings 40). Sleeves, as used in this invention, are durable and well joined extensions placed on a lock, independent Sleeve Bar 43, or Lock Holder 31, that are used to enclose or encase a component of another lock in order to connect the locks together when they are not in use. Sleeves allow the second lock to slide into them when the two locks are secured together, and out of them when the locks are separated for independent use. Sleeves would be designed to fit snugly over the component of the held lock such that the two segments are completely limited in their ability to move independently of one another. They are placed in a position on one or both of the locks, sometimes along with other components including Tabs 25, Ridged Rings 40, Tongues 34 and Grooves 35, so that when the two locks are secured together, they are securely held in place, and so that the two locks can not move independently of one another. In order to secure these two locks together, there may be a combination of one or more Sleeves, and/or Tabs 25, and/or other components mentioned, placed on:
One or both of the U-Shaped Lock's U-Shaped Shackle (22 and 27); and/or
The U-Shaped Lock's U-Shaped Cross Bar (23 and 28); and/or
An independent component, such as Sleeve Bar 43 (as seen in
Also, some variations of this invention include the use of sleeves to secure more than two independent locks together using the same principles of snugly confining the locks together so that, when stored together, they cannot move independently of one another. In some locations where sleeves are used, it may be possible to us a Tab 25 or Clip 49 instead.
25 Tab—Tabs are small flaps, strips, or tongues that extend as an additional appendage on one or more of the components of a lock or lock holder. Tabs are durable, well joined extensions place on a lock, or lock holder, that are used to embrace, firmly butt against or intertwine with part of another lock, when two locks are secured together. Tabs can be used in conjunction with other Tabs, Sleeves 24 or other components such as Ridged Rings 40, Tongues 34 and Grooves 35, in order to ensure that when the two locks are fastened together they may not move independently of one another. Tabs and Sleeves 24 are very similar in purpose, but fundamentally different in that Sleeves completely surround, or encircle, components of a lock whereas Tabs partially embrace the component(s) of a lock without enclosing completely around them.
The terms grooves, ridges and tongues are all described as part of the tab family, since they too can be defined as small flaps, strips, or tongues that extend as an additional appendage. Although a specific variation of a ridge, the Ridged Ring 40 and two variations of a groove, the Grooved Ends 36 and the Tongue and Groove (34 and 35) are identified separately from tabs, the traits or end purposes of these variations place them in the category or family of Tabs 25.
26 Outer U-Shaped Lock—This component is comprised of two main parts that fit together: the Outer Cross Bar 28, and the Outer U-Shaped Shackle 27. This lock is named the Outer Lock since it is the lock that usually, but not necessarily, fits over top of, or outside of, a second lock, the Inner U-Shaped Lock 21, that may be connected inside it when the two locks are fastened or connected together. Other components used to connect the locks may or may not be present as required by the specific variation of this invention being described. These added components include, but are not limited to, Sleeves 24, Tabs 25, Tongues 34, Grooves 36 and Rings 40 which would be features added to the Cross Bar 28 and/or U-Shaped Shackle 27 as needed in order to meet the need of connecting the two locks together, conveniently, when the locks are not in use. Note that many of the design variations of this invention would require that the Inner Lock, (or locks), be locked in their closed position before the Outer Lock can be placed over top of, or around them. Also, in many of the variations of this invention, one of either the Inner or Outer U-Shaped Locks (21 and 26) locks may be of a conventional design, using a lock currently sold in stores, while the other lock, or additional components or lock holders have all the necessary added components to implement the usefulness of this invention. See also Inner U-Shaped Lock 21, (described above).
27 Outer U-Shaped Shackle—See also, Inner U-Shaped Shackle 22, (above).
This component is what gives the “U-Shaped Lock” its' name. It is one of two major components that the Outer U-Shaped Lock 26 is comprised of.
This U-Shaped Shackle is fastened together with the Outer Cross Bar 28 by means of ‘feet’ (see 38 and 39) that fit into, and are secured within, the Outer Aligned Openings 33 on the Cross Bar 28 of the Outer U-Shaped Lock 26.
An example of an alternate shape for a U-Shaped Shackle 22, or 27, is the Piano Shaped lock, U.S. Design Pat. No. D392,540, (McDaid, March 1999).
28 Outer Cross Bar—This component contains both the Outer Aligned Openings 33 and the Lock Case and Locking Mechanism 29 needed to secure the Outer U-Shaped Lock's U-Shaped Shackle 27 to it. Where this invention varies from conventional designs is with regards to the components that can be added to the Cross Bar component, the Outer U-Shaped Shackle 27, or to other components (described in detail herein), in order to meet the need of connecting the two locks together, conveniently, when the locks are not in use. The purpose of these added components would be to connect the other lock(s) to this lock when the two, or more, locks are secured together.
29 Lock Case and Locking Mechanism—These components are all based on conventional designs. They are usually place on the Cross Bars (23 and 28) of a U-shaped lock. Their position and design vary depending on the lock design. This invention will work successfully with any locking Mechanism currently placed on bicycle locks. With some variations the location of these components would be more desirable than others. Although not shown in the figures, this invention will also work with a variety of combination, keyless locks currently available on U-locks, as well as with disc-style cylinder locks currently being placed on newer locks.
30 Bicycle Frame—The body or structure of fitted components, of a bicycle. Bicycle frames can vary significantly in overall design.
31 Lock Holder—Many current Lock Holders used to secure a bicycle lock to the frame of a bicycle can be used with this invention. Some would require minor design adjustments to accommodate the second lock, and still others such as U.S. Pat. No. 5,647,520, (C. McDaid, August 1997), could be adapted specifically for this invention as mentioned in the ‘Detailed Description—Alternate Embodiments’ section. Furthermore, Double Lock Holders 48 are a specific kind of Lock Holder used for the purpose of securing more than one lock on a bicycle. Note the comprehensive description of Lock Holders 31 in the ‘Detailed Description—Preferred Embodiments’. Sections regarding
32 Inner Cross Bar Aligned Openings—The openings that allow the ‘feet’ of the Inner U-Shaped Lock's U-Shaped Shackle 22 to be secured to the Cross Bar 23. Within these openings the locking mechanism secures the ‘feet’ such that the Cross Bar 23 and U-Shaped Shackle 22 are combined as a single locked unit. The locking mechanism within the openings may secure both ‘feet’ as in the case with most locks containing two straight ‘feet’, or one opening may secure a Bent Foot 39 while the other locks and secures a Straight Foot 38.
33 Outer Cross Bar Aligned Openings—The openings that allow the ‘feet’ of the Outer U-Shaped Lock's U-Shaped Shackle 27 to be secured to the Cross Bar 28. Within these openings the locking mechanism secures the ‘feet’ such that the Cross Bar 28 and U-Shaped Shackle 27 are combined as a single locked unit. The locking mechanism within the openings may secure both ‘feet’ as in the case with most locks containing two straight ‘feet’, or one opening may secure a Bent Foot 39 while the other locks and secures a Straight Foot 38.
34 Tongue, of a Tongue and Groove—The male, protruding or projecting component of a joint that has a protruding strip and matching Groove 35 (below). The tongue and groove are used to secure two items in such a way that they can not slip or move in any direction other than on the axis that the two pieces are initially placed together. In the case of this invention the tongue and groove are used on the Sleeve(s) 24, the Cross Bar(s), (23 or 28), the U-Shaped Shackle(s), (22 or 27), and/or on a lock holder (or independent component), with a component on one lock/lock holder having the Tongue 34 and a component on the other lock(s)/lock holder having the Groove 35.
35 Groove, of a Tongue and Groove—The female, hollow or indented component of a joint that has a matching protruding strip that fits into the groove. (See Tongue 34 of a Tongue and Groove, above). Tongue and Groove joints between parts of two different locks, or a lock and a lock holder, may or may not by themselves be a means for the locks to be secured together, they may also be a means to reduce or restrict movement between two locks when they are connected together.
36 Grooved Ends—As seen in
37 Key—These are conventional keys used to secure the conventional Lock Case and Locking Mechanism 29, which in turn are used to secure the U-Shaped Shackles (22 and 27) to the Cross Bars (23 and 28). Although not shown, combination locks, and possibly in the future electronic locks, can eliminate the need to use keys with the accompanying locking mechanism.
38 Straight Foot, on end of the U-Shaped Shackle's, (22 and 27), legs—A variety of conventional designs, all of which consist of a groove of varying size and/or shape, used by the internal locking mechanism to secure the Cross Bar (23 or 28) to the U-Shaped Shackle (22 or 27).
39 Bent Foot, on end of the U-Shaped Shackle's, (22 and 27), legs—A variety of conventional designs, all of which consist of a bend in one of the legs of the U-Shaped Shackle's, (22 and 27), leg. When this Bent Foot 39, (preferably sloping outwardly at an obtuse angle, as seen in many conventional designs), is positioned in its' Aligned Opening (32 or 33) the opposing Straight Foot 38 can be placed it its' Aligned Opening (32 or 33) and locked, thus preventing the bend in the Bent Foot from being removed from the aligned opening unless the other foot is unlocked.
40 Ridged Ring—Ridged Rings serve to prevent movement between the Inner and Outer locks when these two locks are secured together. They would be placed so that a Tab 25, Sleeve 24, Groove 36, or other component described herein, on one lock, (or independent component or lock holder), would be unable to slide or shift due to the positioning of the Ringed Ridge on the other lock, (or independent component or lock holder), when the locks are connected during storage. An entire Ridged Ring may not be necessary, a small ridge, bump or protuberance located directly adjacent to the Tab 25, Sleeve 24, or Groove 36 could restrict the movement of the second lock without necessarily being a ring that completely surrounds the U-Shaped Shackle's, (22 and 27), legs or other section of one of the locks, (or independent component or the lock holder). In the case of
41 Vertical Sleeve—Vertical Sleeves are Sleeves 24 that secure the U-Shaped Shackle, (22 and 27), rather than the Cross Bar(s), (23 and 28). As demonstrated in
42 High Compression Foam—The use of such foam may be desirable, but in many cases it would be optional rather than necessary. An example would be a polyurethane or polyimide foam. The purpose of using foam is to act as a friction-reducing element and to provide a cushion between two locks, or locks and a lock holder, that are secured together. This friction-reducing element would be used such that the space between the connected components of the locks are filled and the locks act more like a single unit: thus reducing any independent shifting or rattling etc. between the said independent parts, when they are connected and/or stored together. This may be particularly valuable to compensate for allowable size tolerances between locks intended to be the same size.
43 Sleeve Bar—The idea of having an independent bar to secure, or connect, at least two locks together side-by-side, as shown in
44 Tab Extension Arm—The purpose of the Tab Extension Arm is to maintain a tight fit between the Tab 25, (attached by the extension arm to the Inner U-Shaped Lock's Shackle 22), and the Outer U-Shaped Lock's Shackle 27 when the two locks are secured together. The utility of a Tab Extension Arm lies in the fact that an Inner U-Shaped Lock 21 can be designed to fit one of several conventional Outer U-Shaped Locks 26, (even from competing manufacturers), since it has components that allow the length of the extension arm to vary in size. There are many possible ways to make a Tab Extension Arm serve its' size varying function, three of which are described in the ‘Detailed Description—Preferred Embodiments’ section below, and shown in
45 Lock Holder Clip—A component, independent of the Lock Holder (31 or 48), that is securely attached to a part of a lock. The clip fastens securely into the lock holder when the lock is not in use. For more information, note the description in the ‘Detailed Description—Preferred Embodiments’ section regarding
46 Lock Holder Clip Release Button—This button, on a Lock Holder 31 or Double Lock Holder 48, releases the Lock Holder Clip 45, attached to the lock(s), from the Lock Holders (31 or 48).
47 Lock Holder Pressure Lever—This ‘quick release’ lever is used to squeeze and tighten the excess space around a lock, placed on a Lock Holder 31 or 48. When the lever is flipped up, and away from the body of the lock holder, the tension on the lever is released, widening the space around the lock, thus allowing the lock to be removed from the lock holder.
48 Double Lock Holder—Double Lock Holders 48 are lock holders, specific to this invention, used for the purpose of connecting or securing more than one lock to a bicycle. Double Lock Holders 48 can serve the purpose of connecting and securing locks together when they are not in use, even when these locks do not have components to help the locks connect together. Note the detailed information on lock holders in the ‘Detailed Description—Preferred Embodiments’: Sections regarding
49 Clip—A clip, as used by this invention, is a fastener that partially surrounds and holds a component of a lock or lock holder. It can be attached to any part of one lock (or lock holder), directly, or with the use of a Cord 50 or Strap 51. Clips can be used in conjunction with other components in order to either assist in securing locks together, or locks to a lock holder, or locks to an independent component, or they can be used along with Cords 50 and/or Straps 51 as the primary means to connect two or more locks together. In some instances a Sleeve 24 may replace a clip and serve a similar function.
50 Cord—A cord is a flexible connection used to attach two components. It can be made from many materials including, but not limited to shock cord, bungee cord, rubber, Polypropylene, as well as cotton, nylon and polyester rope. A cord can be attached to a component and serve as a flexible extension used for fastening items, or it can be an independent component that is used to secure other items.
51 Strap—A strap is a flexible piece of material that is used for binding items together. As used by this invention, a straps is similar to a cord 50 in that it can be attached to a component and serve as a flexible extension used for fastening items, or it can be an independent component that is used to secure other items. Straps can be bound around components of a lock, or lock holder and either secure these items independently on one end of the strap, or they can enclose both items and be bound to themselves as seen in
52 Hinge—A hinge is a movable joint that fastens two components such that they may pivot, rotate or swing in relation to one another, around a fixed axis.
When looking at this invention, the primary use of the locks will be similar to the use and description of any other U-shaped lock as well as many other similar security/utility locks. The convenience of having a second, or even more, locks available gives this invention advantages and added value over other such locks. Where the locks in this invention differ from other locks is in the connecting, combining or fitting together of the locks for storing and traveling purposes.
For ease of description, I will most often describe the linking or connection between just two locks: an Inner U-Shaped Lock 21 and an Outer U-Shaped Lock 26; side-by-side locks, (such as
Regardless of which connected lock(s) have the necessary tabs, sleeves or grooves, for securing the two locks together, the Inner U-Shaped Lock 21 is usually, but not necessarily always, put in its' locked position first, then the Outer U-Shaped Lock 26 is placed over top of, around, or adjacent to the Inner U-Shaped Lock 21 such that it fits into the sleeves, tabs, or grooves, or other components described herein, and then the Outer U-Shaped Lock 26 is closed and locked. Once both locks are connected together in their locked positions, they will not be able to move independently of one another. Note that in some instances if the Inner U-Shaped Lock 21 fits into the sleeves, tabs or grooves of the Outer U-Shaped Lock 26, then the Inner U-Shaped Lock 21 might need to be placed into these sleeves etc. before being locked, (see
For all lock groupings or combinations shown in the Figures, both locks require a key, and for the benefit of ease of use and practicality, (although not necessary), both locks can use the same key.
Note: Some descriptions and operations have already been included in the previous sections, ‘Drawings—Detailed Description Of Reference Numerals’ and ‘Drawings—Other Key Points’.
About The Preferred Embodiments—have invented an improved lock, used primarily for bicycle security as well as other recreational possessions, featuring a second lock, and potentially more locks, which are fastened to, or connected within the confines of, the first lock when these locks are not in use. Although I will primarily focus on the concept of just two U-Shaped Locks, other embodiments and lock styles will be described in further detail.
A U-shaped lock, hereafter named the Inner U-Shaped Lock 21, is secured within, or adjacent to, another U-shaped lock, hereafter named the Outer U-Shaped Lock 26, in order to provide the convenience of two locks, while being stored within a space not significantly greater than the space required to store just one U-shaped lock.
The Inner U-Shaped Lock is secured or connected to the Outer U-Shaped Lock, (or two locks are connected or secured next to each other), by one of five primary means, with other variations, combinations and adaptations shown in the accompanying Figures and described in further detail in the accompanying text.
Each of the five primary means for connecting a plurality of locks have their own Preferred Embodiments. The five primary means for connecting locks together for convenient storage are:
1. The use of Sleeves 24
2. The use of Tabs 25
3. The combination of varied embodiments of primary means 1 and 2 above.
4. The use of primary means 1, 2, and/or 3 to secure locks side-by-side.
5. The use of a component(s) independent of the locks.
The following Preferred Embodiments are described according to the primary means by which they connect two or more bicycles together for convenient storage. References to all Figures are elaborated on in the next section, in order by Figure number. When considering the following Preferred Embodiments, certain changes may be made in the present disclosure without departing from the scope of the present invention, it is intended that all matters described in the foregoing specifications or shown in the accompanying drawings, be interpreted in an illustrative and not limiting sense.
This invention discloses five primary means for connecting locks together for convenient storage. The five primary means are:
1. The use of Sleeves.—Sleeves 24 as described in ‘Drawings—Detailed Description Of Reference Numerals’ are used to connect two or more locks together. Description with examples:
In
2. The use of Tabs.—Tabs 25 as described in ‘Drawings—Detailed Description Of Reference Numerals’ are used to connect two or more locks together.
Description with examples:
In
3. The two locks are secured together by a combination of means listed in Section 1 and/or Section 2 above, or in combination with additional tongues, grooves and/or Rings, (all of which have previously been categorized as members of either the Sleeve 24 or the Tab 25 family in their respective sections within ‘Drawings—Detailed Description Of Reference Numerals’).
Description with examples:
4. The use of any of the above means, mentioned in section 1, 2 and/or 3 above, in order to link two, (or more), locks side-by-side. Side-by-side or tandem locks are secured or held together, or partially nested, when not in use, so that they cannot move independently and so they can be easily stored together. These differ from some of the above mentioned combinations of locks by their relationship in location to one another, (connected next to each other rather than connected with one lock within the confines of another), but still use any of the means of connecting locks together as described above, as well as in section 5, below.
Description with examples:
In
5. The use of an independent component, and/or Clips 49 and/or Straps 51, and/or a Lock Holder 31, or a Double Lock Holder 48 to hold or secure the locks together when the locks are not in use. The locks themselves can be, (but are not necessarily), connected together, instead, they are connected together by means of an independent component. Independent components can house any of the other components mentioned in the primary means 1, 2, 3 and/or 4 mentioned above.
Examples of an independent component include:
A Sleeve Bar 43, that holds the locks side-by side. Two variations can be seen in
A Clip 49 or clips, that secures the two locks together either independently using two or more clips, or in conjunction with other components mentioned in these primary means, as seen in
A Double Lock Holder 48, as seen in
In many instances, a combination of these five primary means of securing and/or storing locks together proves beneficial in order to reduce the opportunity for the locks to shift, move or rattle when secured on a moving bicycle or other vehicle.
Variations—Many variations will be further described that may vary slightly from these primary means, including the use of grooves, ridges or tongues, (all described as part of the tab family), as well as clips, cords, and straps. Some of these will be the primary means which in turn require the use of other means mentioned as secondary, essential, or optional means to assist in securing the locks together. However used, these means all share the common goal of this invention: to connect two or more locks together to gain the advantage of having more than one lock stored conveniently and compactly together when not in use.
U-Shaped Locks—U-shaped locks are considered herein, however as mentioned previously other lock styles are possible and examples are provided to add alternate shaped locks to the scope of this invention, as clearly demonstrated in
Although in this invention the U-shaped locks are secured together when not in use, they are two separate U-shaped locks that work independently, (with the exception of the lock seen in
The following Preferred Embodiments are detailed descriptions of the Figures in the order that they appear. Details concerning these figures are to be interpreted in an illustrative and not a limiting sense.
Furthermore, although not shown, locks that do not have a uniform sized cross bar from one end to the other could still be secured by a Sleeve 24, (note: U.S. Pat. No. 5,257,517, (Dale, November 1993) has a large reinforcing shield that begins at the locking case, located at the cross bar end, and continues along the cross bar to encase the nearest aligned opening on the lock's cross bar). In fact, the lack of uniformity could work as an advantage in limiting the Sleeve 24 from rotating freely when fixed over top of the circular or symmetrical cross bar.
The Inner Lock 21 could be placed in an opposing direction to the Outer Lock 26 such that the outer arc of the Inner Cross Bar 22 has a Tab 25 that rests against the inside of the Outer Cross Bar 28, (See
There are considerable benefits in being able to use a conventional lock along with a lock that houses all the necessary components of this invention, (or an additional component or lock holder that houses all the necessary components of this invention), rather than the addition of this inventions' components to both locks. The two primary benefits of using at least one conventional lock are: that this invention can be used with, and sold either in conjunction with or separately from, a large number of conventional locks that are already on the market (including from competing brands), in order to complete the set of locks; and, the production costs could be significantly lower since only one lock requires different manufacturing than what is currently in production.
The use of Tabs 25 to secure a second lock would be one of several convenient methods to use with Bike Guard® Lock Jaw and Bonelocks as well as The Club®'s Ultra Bike Club™ since the hinges 52 as well as the curves of these oval-shaped locks would make Tabs 25 more convenient than Sleeves 24. See
[A ‘magnet’ shaped lock can be seen in FIG. 13 of U.S. Pat. No. 4,155,231, (Zane, et al., May 1979)].
All seven of the above mentioned figures,
Although fundamentally different in design, a lock with similar functioning can be seen in U.S. Pat. No. 5,622,066, (Shallis, April 1997). This lock uses a rigid link added to one of the U-shaped shackle's legs to create a single lock with two U-shaped areas to secure items in.
In this Grooved Cross Bar Ends 36 variation the lock case and locking mechanism 29 would be more conveniently placed on the length of the Cross Bar 23 rather than on the outside ends where the Grooved Ends 36 are, since a tight fit is recommended between the Inner and Outer locks. These Grooved Ends 36 are a variation of Tabs 25 that are placed on the outside ends of the Inner Cross Bar 23 rather than along the length of the Inner Cross Bar 23 as shown in
Just as
a) Distributing the weight of the locks more evenly on the bicycle, and
b) Securing the locks in two different areas so that they are less likely to move around during bumpy rides, such as when mountain biking on trails.
This embodiment also shows a way in which the locks can be combined in order to extend the distance from which a bicycle can be securely locked to a, hard to reach, secure, fixed and immovable object. This embodiment can also be an example of a way to secure the lock with a Single Rotating Cross Bar, seen in
Note that this variation, and the ones below, all permit the locks to be fitted together with the Inner U-Shaped Lock's Sleeve 24 such that the locks can be locked opposing each other as shown in
The length of the sleeve(s) can vary for
This embodiment can also be further described as a Tongue 34 and Groove 35 assembly whereby the Ridged Ring 40 is described as a raised Groove 35 and the Tab 25 is described as a protruding Tongue 34. Either way, the ‘male’ and ‘female’ parts serve to secure the two locks, connected together, such that they cannot move independently when stored together. This assembly can be used in conjunction with Sleeves 24, or other components described herein. For example the Tabs 25 and Ridged Rings 40 on the Cross Bars 23 and 28 can be accompanied by a Tab 25 that looks more like the one seen on the outer edge of the Inner U-Shaped Shackle 22 as in
There are many options for the design of this version including:
a) The independent Sleeve Bar 43 can house components that make it easier to be mounted onto a bicycle, see
b) The Sleeve Bar 43 can be connected to one of the Cross Bars (23 or 28 so that it serves as a sleeve for only the other lock. This is a combination between the Cross Bar 23 in
c) The Sleeve Bar 43 can be contoured to reduce its' overall weight, as seen in
d) The Sleeve Bar 43 could secure just one of the two arms of each lock with either Ridged Rings 40 or an extension below the sleeve to hold or clamp on to a section of the locks' Cross Bars (23 and 28) in order to prevent the two locks from moving independently when secured together. A version of this that considers both the ridged ring and the extension is described in
e) The Sleeve Bar 43 could be designed to house more than two locks. Although not shown,
f) The Sleeve Bar 43 can secure nested locks. If
Side-by-side locks can be useful since these locks can both be equally large. For example, a motorbikes would be a location where the size of the locks may need to be significantly larger compared to designs that have the Inner 21 lock that is somewhat smaller than the accompanying Outer 26 Lock.
Further variations for a Tab Extension Arm 44 can be seen in
There are many components that the Lock Holder Clip 45 can fasten to so that two locks can be secured in a lock holder of a conventional design such as the one shown in this figure, including:
There can be many variations of Clips 49 that can be placed in a variety of locations in order to secure two locks together. As seen in the variations shown in these figures, the Clip 49, Cord 50, and Strap 51 can be considered components of a Tab Extension Arms 44, as first seen in
Note: Some Dimensions and Materials have already been included in previous sections, primarily in the ‘Drawings—Detailed Description Of Reference Numerals’ section and throughout the Preferred Embodiments.
There are a variety of prior art locks related to this invention that are currently on the market. These related locks vary significantly in size. Some of the larger bicycle locks on the market include:
The Oxford® Hercules OF144 which is 7.08″×12.59″ (18 cm×32 cm),
The ABUS® Sinus Plus 47 Lock which is 5.9″×11.8″ (15 cm×30 cm),
The ABUS® Granite Extreme Lock which is 7.08″×10.23″ (18 cm×26 cm),
The Kryptonite® Evolution 2000 ATB which is 5″×9″ (12.7 cm×22.9 cm), and
The Kryptonite® Evolution 2000 LS, (and the Kryptolock MC Motorcycle U-Lock), which are both 4″×11.5″ (10.2 cm×29.2 cm).
All of these locks, as well as locks larger than this, (for example motorcycle locks), would make ideal sizes for an Outer U-Shaped Lock 26, or two side-by-side locks. The accompanying Inner U-Shaped Lock 21 would be slightly smaller, but still fully useful to secure the bicycle.
Looking at the smaller end, in an extreme example, a width as small as 4 cm and a length of 12 cm, (measuring between and inside the shackle legs for length, and from inside the cross bar to the inside of the arc of the u-shaped shackle), an Inner U-Shaped Lock 21 would easily fit into any of the locks mentioned and still be able to be locked through the back wheel of most bicycle designs; with one Shackle leg inside and the other Shackle leg outside the two Top Stays and Chain Stays on the rear wheel of a Bicycle Frame 30, thus securing the rear wheel to the frame. With the smaller lock securing the rear wheel to the frame, the larger Outer Lock can secure the front wheel to the main frame of the bicycle as well as to a fixed, secure object that the bicycle is being secured to. Many of the two-lock variations in the Figures can have Inner U-Shaped Locks 21 that are significantly larger than, and even more functional than, the 4 cm×12 cm example size specifications.
As the Outer lock gets smaller in design, the Inner lock must be proportionately smaller too, and so some of the smaller designs such as Kryptonite®'s Evolution 2000 Mini which is 3″×5.5″ (7.6 cm×14 cm) may be too small to serve as an Outer Lock, but would still be fully functional as a side-by-side or Inner Lock. Also, as mentioned when referring to motorcycle locks, larger locks are both possible and functional. Furthermore, with respect to side-by-side locks and locks connected by an additional component such as a Sleeve Bar 43 or Lock Holder 31 and 48, since the locks can be equal in size, their size and shape can vary beyond the specifications mentioned above.
The materials used on current conventional locks on the market can be used in the construction of this invention. U-Shaped Shackles (22 and 27) can be made of, (but are not limited to), heat treated, high-grade, hardened steel. They are usually, but not always, made of solid cylindrical, (or other shaped), rod stock. They are significantly sturdy and thick to provide significant resistance to hack saws, bolt cutters and levers.
Cross Bars (23 and 28) can also be made of, (but are not limited to), heat treated, high-grade, hardened steel. They are usually hollow/tubular so that they can house the Lock Case and Locking Mechanism 29 and the Shackle ‘Feet’ (38 or 38 and 39). Most locks are covered with a protective layer of rubber, plastic or vinyl. This protective layer not only protects the lock, but also the bicycle, as the lock components are placed and locked onto, and removed from, the bicycle during everyday use. Any of these materials used on conventional locks can be used on this invention. However, some components such as Tabs 25 may require special attention or application of the protective layer. For example a rubber sleeve traditionally used on the U-Shaped Shackles (22 and 27) of some conventional locks may not fit easily over a Tab 25 located on that U-Shaped Shackles (22 and 27). Therefore, alternate means of putting the protective layer on such components may be required, such as dipping or spraying the components with the protective layer. Also not shown, but fully functional with this invention are conventional lock covers.
None of the invention's variations shown require a lock or locking mechanism that is constructed differently than those currently used by existing, conventional designs, and many future designs will also function equally as well.
Almost all additional components including, but not limited to, Sleeves 24, Tabs 25, Tongues 34, Grooves 35, ridged Rings 40, Vertical Sleeves 41, Sleeve Bars 43, and Lock Holders 31 can again be made of, (but are not limited to), heat treated, high-grade, hardened steel. The thickness of these components will depend on the component and its' function, but they will be sturdy enough to insure durability. Note that since these components are necessary for securing the locks together when stored and do not compromise the security of the lock, they need not be as thick and strong as the U-Shaped Shackles (22 and 27) and the Cross Bars (23 and 28).
The High Compression Foam 42 as well as the size varying components of the Tab Extension Arm 44 are conventional in construction and/or materials. They are used by this invention for specific purposes described herein.
Although many of these embodiments have already been presented, this section expands on the use of this invention in ways that may not have been explicitly covered.
Two, or more connected U-Shaped Locks can be used in conjunction with a motorcycle, trailer, bicycle or utility hitch, motor home, motor scooter, moped, go-cart, motorized bicycle, or other recreational vehicle/valuable possession. Other uses may also be served when camping, or fishing, or on construction/worksites, or anywhere where the use of more than one U-lock is desired along with the efficiency of storing the locks conveniently together.
The locks need not be U-Shaped Locks, but rather they may be of an alternate shape, preferably, but not necessarily, with both locks being rigid and thus more secure than current cable and chain locks. Furthermore, the locks need not be similar in style or design in order to be connected. This invention can also be used to connect a rigid lock to a cable or chain lock, or other less rigid or other shaped lock. See
Flexible locks can be connected. Components, described in the five primary means for connecting locks, can be used in ways that this patent suggests, to secure a flexible lock within, or adjacent to another lock that is either rigid or flexible.
Connected locks can also be stored within some flexible locks. The STOCKS LOCKS® Original Stocks Lock and SuperStocks Lock, are two flexible U-locks that are examples of flexible, yet still very durable and secure locks that can serve as effective Outer Locks 26, (smaller versions of this lock could serve as Inner Locks 21, or these locks could also be connected adjacent to each other).
A lock can be placed inside of a fixed or anchored lock such as the Oxford® Defiance Ultra Strong Anchor. The Inner U-Shaped Lock 21 stored here can be used to secure the unlocked wheel, or a helmet, while the motorcycle is secured conveniently inside this anchored, pivoting motorcycle lock. This added inner lock could be shaped differently (than a traditional U-lock) in the above mentioned square lock, (or another anchor lock), in order to maximize the space within this lock, (for example see the Inner Lock 21 in
More than two locks may be fitted together or secured side-by-side, (i.e. side-by-side-by-side), or side-by-side locks may also have locks fitted within them. See
The lock(s) can house components that assist them in being secured on to a bicycle or other location. See Lock Holder Clip 45 in
A single lock may be sold with components of this invention so that it can be stored or connected with other currently existing locks, or a group of locks with varying specification.
Components of this invention can be used to secure one or more locks into a confined area, or segment of a bicycle frame, without the aid of an independent lock holder.
Locks can serve to secure panniers, (and potentially lock them shut), to a bicycle so that these panniers may be left secured to the bicycle. Other components such as helmets or backpacks or other gear may be secured to a bicycle using one or more of the locks. Although many of these items may not currently have components, holes or sections of them that are favorable to being locked with a U-lock, this may be a result of U-locks not traditionally having enough space to secure these items. With a second lock stored on a bicycle, many items could be redesigned significantly, or just slightly, to accommodate the use of a second lock on a bicycle to secure such items.
Alternate Embodiments Incorporating Prior Art—More ideas for securing this invention to a bicycle include:
a) Adapting U.S. Pat. No. 5,647,520, (C. McDaid, July 1997) where the spline(s) described may be placed on either the outside of the sleeve of the invention's inner lock 24 (Possible on a variation such as
b) One similar design to McDaid's spline patent, called the “Lickity Click” and seen on Bike Guard® locks, has a Tongue 34 assembly attached to the Bicycle Frame 30 and a matching Groove 35 assembly on a Lock Holder Clip 45 secured to one of the legs of the U-Shaped Shackle (22 and 27), (See
c) U.S. Pat. No. 6,422,442, (C. McDaid, et al., July 2002) with a flexible brace and collar can be used whereby two of these lock holders, or lock holders that serve a similar function, would be used as drawn in
In many instances, where the use of a portable (primarily U-shaped) lock is convenient, there proves to be both benefit and convenience to having a second portable (primarily U-shaped) lock. Furthermore, the ability to store these locks in a limited space, not significantly greater than securing a single lock is desirable.
In the case of securing a bicycle, a U-Shaped Lock is often used to lock the rear wheel to the frame of the bicycle and to a post, or pole, or other object that is fixed and secure. Often at least one of several challenges are faced, including:
1. Removing the quick-release front wheel and locking it in the U-Shaped Lock with the items mentioned above. This involves removing and replacing the front brake wire.
2. A front wheel that is bolted, and not quick-release, can easily be stolen if further measures are not taken to protect it.
3. Finding other means to lock the front wheel, such as making space on the bicycle, or in a pack, in order to carry a chain or cable style lock or a second U-Shaped Lock.
4. The pole/post/park bench or other object that the bicycle will be secured to is too large and cannot fit within the U-Shaped Lock when all other parts of the bicycle, such as the front wheel, are also placed within the U-Shaped Lock.
5. When using just one U-Shaped Lock, it is often necessary to place the lock close to the ground where it is easier for thieves to get leverage, which can aid in the theft of a bicycle.
6. Other items that would be convenient to secure cannot fit in the U-Shaped Lock when all other said parts of the bicycle, motorcycle or other valuable possession are also placed within the U-Shaped Lock.
7. Many bicycle racks, used to transport bicycles outside of a vehicle, require additional lock(s) to secure the bicycle, and/or components of a bicycle, to help prevent against theft.
8. Parents of younger children will often ride to a park or to a child's sporting event location and their younger children may not have a lock or room for a lock on their bicycle.
The advantages of this invention, having two U-shaped locks fastened together as one unit when stored, alleviates the challenges and inconveniences mentioned above:
1. With a second U-Shaped Lock, the front wheel can remain on the bicycle and be locked to the frame, and/or the secure object, separately from the lock used at the rear wheel, (which could be locked to a different part of the secure object for added security).
2. A bolted front wheel, that is not quick release, can be locked for added security, in addition to the rear wheel and frame.
3. No more storage is necessary for a second lock than the space already needed for the first lock. Also a second U-Shaped Lock provides greater security than a chain or cable lock.
4. The second lock can be used to secure the bicycle to the pole/post/park bench or other object, especially when the first lock is not adequately large enough to do so as well as secure everything else mentioned previously. For example, a 2′×4′ plank on a park bench would not fit in most U-Shaped Locks along with the rear wheel and bicycle frame, much less other bicycle components. One of the two U-Shaped Locks can be used solely to lock the frame of the bicycle to larger secure objects.
5. A second lock acts as a greater deterrent to thieves who would rather prey on an easier target with just a single lock to overcome. Also, this second lock can be placed in a position that either locks the bicycle frame to the secure object a second time, (in addition to the first lock), or locks the bicycle frame to a second secure object. Also, with the first lock already securing the bicycle, the second lock can lock the bicycle frame, a second time, in a position that restricts a thiefs access to the second lock.
6. Items such as another bicycle, or a motorcycle helmet, can be secured despite the fact that the other lock is in use and has no room to fit such items.
7. Storing 2 locks together provides the versatility of carrying and storing two locks in the space provided for just one lock, (even when the locks are not stored on the bicycle). So, both locks can be made available, to secure a bicycle to a rack on a vehicle, when the locks are kept, conveniently together, on a bicycle, in the vehicle or anywhere else in the possession of the user. Also, the second lock can secure the front wheel of one bicycle to the rear wheel and frame of another bicycle when both bicycles are placed on a bicycle rack in opposing directions.
8. Parents can have the convenience of two locks on their bicycle so that they can secure their bicycle as well as their children's.
Many web sites that relate to bicycle security, which provide security tips for locking and securing bicycles, make two notable points:
U-shaped locks provide greater security than chain or cable locks.
Always secure additional bicycle components/accessories.
(Specifically taken from: http://www.nationalbikereg istrv.com/proplock.html)
This invention gives the user the security of a second bicycle lock for locking components, such as the front wheel, and the advantage of storing the second lock conveniently next to, or within, the confines of the first lock.
The advantages listed above demonstrate the usefulness of this invention as it pertains to bicycles and U-locks. As suggested in #6 above, there are advantages as well for motorcycle users, (to lock their helmets for example). This list of advantages could easily be expanded when factoring in other items being secured besides just bicycles and cycling related equipment. Furthermore, one or more of the locks secured or connected to one another may not necessarily be of a current conventional design, without diminishing the usefulness of this invention.
Although conventional locks and more specifically U-Shaped Locks are plentiful, none possess the convenience, or added security of providing a second U-Shaped Lock, (or other shaped lock), fastened to, and stored in conjunction with, the original U-Shaped Lock, (or other shaped lock). Furthermore, this invention is useful because:
It can be sold in conjunction with a conventional lock design.
It can be sold to retrofit the after market purchase of a conventional lock design.
It can combine locks that are completely different in design.
It can store additional, independent locks within the confines of a single lock.
It provides additional security and deterrent to theft compared to single lock designs and multi-lock combinations currently on the market.
It provides additional convenience compared to single lock designs and multi-lock combinations currently on the market.
It provides more volume than what can be stored in any other U-lock, or similar sized lock, without taking up significantly more area on a bicycle.
There are five primary means for connecting together bicycle locks for convenient storage that are covered by this patent:
1. The use of Sleeves 24
2. The use of Tabs 25
3. The combination of varied embodiments of primary means 1 and 2 above.
4. The use of primary means 1, 2, and/or 3 to secure locks side-by-side.
5. The use of a component(s) independent of the locks.
Locks stored together on a bicycle may be:
Connected with one lock stored within the confines of a second lock, when these locks are not being used to secure the item(s) they were purchased to secure; and/or
