Aspects of this document relate generally to bicycle multi-tools with a quicklink removal tool.
In the course of use, the chain of a bicycle is subjected to the strain of turning the geared wheel, in addition to the vibrations, jolts, and exposure to the elements inherent to bicycle riding. As a result, bicycle chains will occasionally break. A typical method for attaching two ends of a broken chain together is by using what is called a quicklink.
Quicklinks may be installed quickly and without the use of tools; the locking force is often applied by simply pressing on the pedal of the bicycle to pull the chain taut. However, the removal of a quicklink requires the use of a special tool to compress the link.
Trail and roadside repairs are often necessary. Although there are a variety of quicklink removal tools available, they are generally designed for use in a garage or workshop, and are sold individually with a primary, and sometimes only, functionality being that of removing a quicklink. Devoting that much space and weight to a single purpose tool whose necessity is irregular is not practical for a bike rider away from the workshop, where weight capacity and cargo space are at a premium.
According to one aspect, a bicycling multi-tool may comprise a quicklink removal tool threadedly coupled to the multi-tool, wherein the quicklink removal tool may comprise a body comprising a fixed prong integral with the body and protruding from the body in a first direction, and a first aperture proximate the fixed prong, a floating prong base comprising a second prong integral with the floating prong base and protruding from the floating prong base in the first direction, the floating prong base comprising a second aperture and a sliding face, the floating prong base slideably coupled to the body through a bolt passing through both the first aperture and the second aperture, the bolt threadedly coupled to at least one of the first aperture and the second aperture, the face of the floating prong base positioned proximate to and facing a sliding surface of the body, a rotational tool sized and shaped to mate with a head of the bolt of the quicklink removal tool, a tool having a quicklink storage surface comprising at least two recesses, each recess shaped to receive a side and an integral post of a half of a quicklink, at least one screwdriver, a chainbreaker tool, and a plurality of hex head wrenches, wherein the quicklink removal tool is pivotally coupled to the multi-tool such, pivotable about an axis between a closed position and an open position, wherein turning the bolt drives the floating prong base towards and away from the fixed prong, wherein the sliding surface is part of a groove in the body of the quicklink removal tool in which the floating prong base is seated and along which the floating prong base slides as the bolt is turned, and wherein the bolt has a length between 1 cm and 4 cm.

Aspects and applications of the disclosure presented here are described below in the drawings and detailed description. Unless specifically noted, it is intended that the words and phrases in the specification and the claims be given their plain, ordinary, and accustomed meaning to those of ordinary skill in the applicable arts. The inventors are fully aware that they can be their own lexicographers if desired. The inventors expressly elect, as their own lexicographers, to use only the plain and ordinary meaning of terms in the specification and claims unless they clearly state otherwise and then further, expressly set forth the “special” definition of that term and explain how it differs from the plain and ordinary meaning. Absent such clear statements of intent to apply a “special” definition, it is the inventors' intent and desire that the simple, plain and ordinary meaning to the terms be applied to the interpretation of the specification and claims.
The inventors are also aware of the normal precepts of English grammar. Thus, if a noun, term, or phrase is intended to be further characterized, specified, or narrowed in some way, then such noun, term, or phrase will expressly include additional adjectives, descriptive terms, or other modifiers in accordance with the normal precepts of English grammar. Absent the use of such adjectives, descriptive terms, or modifiers, it is the intent that such nouns, terms, or phrases be given their plain, and ordinary English meaning to those skilled in the applicable arts as set forth above.
Further, the inventors are fully informed of the standards and application of the special provisions of 35 U.S.C. § 112, ¶ 6. Thus, the use of the words “function,” “means” or “step” in the Detailed Description or Description of the Drawings or claims is not intended to somehow indicate a desire to invoke the special provisions of 35 U.S.C. § 112, ¶ 6, to define the invention. To the contrary, if the provisions of 35 U.S.C. § 112, ¶ 6 are sought to be invoked to define the inventions, the claims will specifically and expressly state the exact phrases “means for” or “step for”, and will also recite the word “function” (i.e., will state “means for performing the function of [insert function]”), without also reciting in such phrases any structure, material or act in support of the function. Thus, even when the claims recite a “means for performing the function of . . . ” or “step for performing the function of . . . ,” if the claims also recite any structure, material or acts in support of that means or step, or that perform the recited function, then it is the clear intention of the inventors not to invoke the provisions of 35 U.S.C. § 112, ¶ 6. Moreover, even if the provisions of 35 U.S.C. § 112, ¶ 6 are invoked to define the claimed aspects, it is intended that these aspects not be limited only to the specific structure, material or acts that are described in the preferred embodiments, but in addition, include any and all structures, materials or acts that perform the claimed function as described in alternative embodiments or forms of the disclosure, or that are well known present or later-developed, equivalent structures, material or acts for performing the claimed function.
The foregoing and other aspects, features, and advantages will be apparent to those artisans of ordinary skill in the art from the DESCRIPTION and DRAWINGS, and from the CLAIMS.
The invention will hereinafter be described in conjunction with the appended drawings, where like designations denote like elements, and:
This disclosure, its aspects and implementations, are not limited to the specific material types, components, methods, or other examples disclosed herein. Many additional material types, components, methods, and procedures known in the art are contemplated for use with particular implementations from this disclosure. Accordingly, for example, although particular implementations are disclosed, such implementations and implementing components may comprise any components, models, types, materials, versions, quantities, and/or the like as is known in the art for such systems and implementing components, consistent with the intended operation.
The word “exemplary,” “example,” or various forms thereof are used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” or as an “example” is not necessarily to be construed as preferred or advantageous over other aspects or designs. Furthermore, examples are provided solely for purposes of clarity and understanding and are not meant to limit or restrict the disclosed subject matter or relevant portions of this disclosure in any manner. It is to be appreciated that a myriad of additional or alternate examples of varying scope could have been presented, but have been omitted for purposes of brevity.
While this disclosure includes a number of embodiments in many different forms, there is shown in the drawings and will herein be described in detail particular embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the disclosed methods and systems, and is not intended to limit the broad aspect of the disclosed concepts to the embodiments illustrated.
In the course of use, the chain of a bicycle is subjected to the strain of turning the geared wheel, in addition to the vibrations, jolts, and exposure to the elements inherent to bicycle riding. As a result, bicycle chains will occasionally break. A typical method for attaching two ends of a broken chain together is by using a quicklink.
Unlike their installation, the removal of a quicklink 800 requires the use of a special tool to compress the link, pushing the posts 806 toward the middle such that posts 806 are in the wider end of the slots 808, and the sides 804 are offset from each other. Once unlocked, the quicklink halves 802 may be separated. Typical conventional quicklink removal tools resemble pliers.
Trail and roadside bicycle repairs are often necessary. Although there are a variety of quicklink removal tools available, they are mostly designed for use in a garage or workshop, and are typically sold individually with a primary, and sometimes only, functionality being that of removing a quicklink. Devoting that much space and weight to a single purpose tool whose necessity is irregular is not practical for a bike rider away from the workshop, where weight capacity and cargo space are at a premium.
Contemplated herein is a bicycle multi-tool having a compact quicklink removal tool. Most riders carry some form of small, bicycle-specific multi-tool to perform repairs when away from a workshop. The multi-tool contemplated herein comprises a compact quicklink removal tool that may be removed from the multi-tool and used to unlock an installed quicklink. The compact quicklink removal tool comprises two prongs that may be used to compress the posts of a quicklink together through the turning of a bolt. The compact quicklink removal tool does not substantially increase the size, weight, or profile of the multi-tool, allowing for roadside quicklink removal without having to carry any of the bulky, single-use tools conventionally used.
As shown, the quicklink removal tool 102 comprises a body 104 having a fixed prong 106, a floating prong base 110 with a second prong 112, and a bolt 118. The fixed prong 106 is integral with the body 104 of the quicklink removal tool 102. In the context of the present disclosure, floating means that the floating prong base 110 has the ability to move with respect to the fixed prong 106 and the quicklink tool body 104 while remaining coupled to the body 104; in this example through the bolt 118. Although fixed prong 106 is referenced as a fixed prong, it will be understood by those of ordinary skill in the art that in some embodiments the fixed prong 106 may also be a floating prong if the bolt 118 is replaced with a dual side threaded bolt with threads going in both directions so that when it is twisted in a first direction, the two floating prongs attached to the bolt will move apart from each other and when the bolt is twisted in a second direction, the two floating prongs attached to the bolt will move closer to each other. Thus, where the fixed prong 106 is discussed herein, unless the description requires a fixed component, the description is intended to apply to a first floating prong 106.
As the bolt 118 is turned, the floating prong base 110 is driven towards or away from the fixed prong 106, depending on the direction the bolt 118 is turned in. In some embodiments, the head 120 of the bolt 118 may be compatible with (i.e. sized and shaped to mate with) a rotational tool 126 such as a wrench or other tool present on the multi-tool 100. As a specific example, the bolt 118 may be turned with a 4 mm hex head wrench. In other embodiments, the head 120 of the bolt 118 may be knurled, to provide grip for manually turning the bolt with fingers. The hex head wrench, such as an Allen wrench or other brand hex head wrench, or other turning tool may be included on the multi-tool 100.
According to various embodiments, the bolt 118 passes through a first aperture 108 in the body 104, as well as a second aperture 114 in the floating prong base 110. As shown, the first aperture 108 may be aligned with the first, or fixed, prong 106. In some embodiments, including the non-limiting example shown in
In other embodiments, the first aperture 108 in the body 104 may be threaded, such that turning the bolt 118 causes the bolt 118 to move in or out of the quicklink tool body 104. The floating prong base 110 (and thus, the second prong 112) may be rotatably coupled to the bolt 118, such that it moves linearly along its rotational axis with respect to the fixed prong 106 as the bolt 118 moves in or out of the first aperture 108.
According to various embodiments, the floating prong base 110 has at least one sliding face 116 that is positioned proximate to and facing a sliding surface 124 of the body 104. Such an interface provides stability as well as restricts the rotation of the floating prong base 110 with respect to the body 104.
As shown in
The range of motion of the floating prong base 110 with respect to the fixed prong 106 is bounded, at the least, by the length 200 of the bolt 118. According to various embodiments, the quicklink removal tool 102 is sized such that it may be used to remove a quicklink 800 while still being able to be incorporated into a bicycling multi-tool 100. In some embodiments, the bolt 118 may range in length 200 between 1 cm and 2 cm. In other embodiments, the bolt length 200 may range between 1 cm and 2.5 cm, in other embodiments, the bolt length 200 may range between 1 cm and 3 cm, and in still other embodiments, the bolt length 200 may range between 1 cm and 4 cm, each length range having its own particular advantage and application. The length 200 of the bolt 118 used may depend upon the size and shape of the body 104 and/or floating prong base 110 that it is being used with.
As shown in
In some embodiments, the prongs may be similarly curved in the opposite direction on their outside edges as well, allowing the tool 102 to be used to install a quicklink 800 by putting the two prongs between the two quicklink posts 806 and turning the bolt 118 to spread the prongs apart until the posts 806 engage the narrow end of the slots 808.
Specifically, in some embodiments, the exterior surface 314 of the fixed prong 106 that faces away from the second prong 112 is curved away from the second prong 112 and the exterior surface 316 of the second prong 112 that faces away from the fixed prong 106 is curved away from the fixed prong 106, such that the distal end 318 of the exterior surface 314 of the fixed prong 106 is further away from the distal end 320 of the exterior surface 316 of the second prong 112 than the middle 322 of the exterior surface 314 of the fixed prong 106 is to the middle 324 of the exterior surface 316 of the second prong 112. Of course, since a tool is not explicitly required to install a quicklink 800, the prongs of other embodiments may not curve outward in such a fashion, and in other embodiments the prongs may not curve at all and may be straight.
According to various embodiments, the quicklink removal tool 102 is pivotally coupled to the multi-tool 100 such that it can pivot between an open position 134 (see
In other embodiments, the quicklink removal tool 102 may be deployed for use through a different mechanism, such as sliding, twisting, or any other known in the art. Furthermore, it should be clear to one skilled in the art that the quicklink removal tool 102 contemplated herein may be incorporated with a variety of multi-tools, and may be adapted for use as part of any bicycle multi-tool known in the art.
According to various embodiments, the quicklink removal tool 102 may be located on one side of the multi-tool 100, and may rest in a plane perpendicular to the fold out path of other tools. In
In some embodiments, the quicklink removal tool 102 may be built into another tool on the multi-tool 100. For example, as shown in
According to various embodiments, the quicklink removal tool 102 may be releasably coupled to the multi-tool 100. Detaching the quicklink tool from the multi-tool may facilitate its use on a chain that is still attached to a bicycle, and make the operation itself easier. For instance, detaching the quicklink removal tool 102 would allow the head 120 of the bolt 118 to be rotated using another tool 126 on the multi-tool 100, giving the user additional torque and making the quicklink removal process easier.
In some embodiments, the quicklink removal tool 102 may be threadedly coupled to the multi-tool 100. For instance, in the non-limiting example shown in
As shown, the bicycling multi-tool 100 may comprise a number of additional tools, including a chainbreaker 130, one or more screwdrivers 128, a rotational tool 126 configured for use with the head 120 of the bolt 118 of the quicklink removal tool 102, a plurality of hex head wrenches 132, and/or any other tools known in the art to be needed while away from a garage or workshop and able to be incorporated into a multi-tool.
In some embodiments, the multi-tool 100 may also comprise replacement quicklink parts. Quicklink halves 802 are small, easy to lose in a bike bag, and may be hard to find when needed. Storing replacement quicklink 800 parts in a recessed tool on the multi-tool 100 makes them conveniently on hand if the quicklink removal tool 102 is ever needed. According to various embodiments, the quicklink parts may be stored in the recessed surface of another tool, without interfering with its use.
According to various embodiments, the quicklink removal tool 102 may be sized (e.g. the bolt 118 and body 104 may be sized) such that it may be used with a variety of bicycle chain sizes, and may be incorporated with a traditional multi-tool without significantly changing the overall dimensions of the tool. Furthermore, the quicklink removal tool 102 may be composed of metal, thermoplastic, or any other material known in the art for construction of bicycle tools, particularly bicycle multi-tool elements.
Where the above examples, embodiments and implementations reference examples, it should be understood by those of ordinary skill in the art that other tools and multi-tools could be intermixed or substituted with those provided. In places where the description above refers to particular embodiments of multi-tools and quicklink removal tools, it should be readily apparent that a number of modifications may be made without departing from the spirit thereof and that these embodiments and implementations may be applied to other to multi-tools as well. Accordingly, the disclosed subject matter is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the disclosure and the knowledge of one of ordinary skill in the art.
This application claims the benefit of U.S. provisional patent application 62/550,544, filed Aug. 25, 2017 titled “Multi-Tool with Quicklink Removal Tool,” the entirety of the disclosure of which is hereby incorporated by this reference.
