Title: Firearm Handguard Cable Organizer

Description:
TECHNICAL FIELD 
     The present disclosure is generally related to firearms and, more particularly, to a handguard cable organizer for firearms. 
     BACKGROUND 
     Unless otherwise indicated herein, approaches described in this section are not prior art to the claims listed below and are not admitted as prior art by inclusion in this section. 
     A handguard (also known as forend or forearm) on a firearm refers to a guard attached to the front portion of the firearm to shield or otherwise protect a user from the barrel of the firearm, which can become very hot when firing. On an AR-style or AK-style firearm, whether a rifle, carbine, pistol or shotgun, the handguard is typically secured on a barrel nut of the firearm by either screws or another locking mechanism which requires tools to operate. With the handguard installed, the barrel of the AR-style or AK-style firearm (which typically includes a gas block, a gas tube or a piston system) is at least partially surrounded by and shielded inside the handguard. 
     The user can choose to mount or otherwise install one or more mechanical and/or electronic accessories on the handguard. Certain electronic accessories, such as light and/or laser, may have an ON/OFF switch connected to the light or laser via a cord or cable so that the light and/or laser can be mounted towards the front end of the firearm on the handguard (e.g., closer to a muzzle of the barrel) while the switch is mounted somewhere rearward on the handguard to be closer to the user for ease of reach by a hand or finger(s) of the user. As different firearms can have different barrel lengths (and hence different lengths for the handguard), the length of the cord or cable of an electronic accessory, which is usually fixed, tends to be long in order to accommodate firearms with a long handguard. However, when the electronic accessory is installed on a firearm with a short handguard, the length of the cord or cable of the electronic accessory could be relatively excessive and thus difficult to organize. For instance, an excessive long cable could cause the cable to tangle easily. Even worse, the excessive length could catch objects during usage (e.g., firing) of the firearm, thereby imposing a safety hazard. Therefore, there is need for a solution of a firearm handguard cable organizer.

     DETAILED DESCRIPTION OF PREFERRED IMPLEMENTATIONS 
     Detailed embodiments and implementations of the claimed subject matters are disclosed herein. However, it shall be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matters which may be embodied in various forms. The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided so that description of the present disclosure is thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art. In the description below, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations. 
     The position terms used in the present disclosure, such as “front”, “forward”, “rear”, “back”, “top”, “bottom”, “left”, “right”, “head”, “tail” or the like assume a firearm in the normal firing position, with the firearm being in a position in which the longitudinal axis of the barrel of the firearm runs generally horizontally and the direction of firing points “forward” away from the operator or user of the firearm. The same convention applies for the direction statements used herein. 
     As used herein, the terms “proximal” and “proximally” may denote “forward” and “forwardly” with respect to the firearm, and the terms “distal” and “distally” may denote “rearward” and “rearwardly” with respect to the firearm. As used herein, the verb “to comprise” in this description, claims, and other conjugations are used in its non-limiting sense to mean those items following the word are included, but items not specifically mentioned are not excluded. As used herein, the word “forward” means moving in the direction that the projectile moves during firing a firearm. As used herein, the word “proximal” means closer to the reference point, in this case, the shooter. As used herein, the word “distal” means farther to the reference point, in this case, the shooter. Reference to an element by the indefinite article “a” or “an” does not exclude the possibility that more than one of the elements are present, unless the context clearly requires that there is one and only one of the elements. The indefinite article “a” or “an” thus usually means “at least one.” Additionally, the words “a” and “an” when used in the present document in concert with the words “comprising” or “containing” denote “one or more. 
     All numeric values are herein assumed to be modified by the term “about,” whether or not explicitly indicated. The term “about” generally refers to a range of numbers that one of skill in the art would consider equivalent to the recited value (i.e., having the same function or result). In many instances, the terms “about” may include numbers that are rounded to the nearest significant figure. The recitation of numerical ranges by endpoints includes all numbers within that range (e.g. 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, and 5). All dimensions given herein are by way of examples to better illustrate the present disclosure embodiments and shall not be construed to limit the dimensions of the present disclosure embodiments to the given numeric values. 
     Overview 
     The following description is provided with reference to  FIG.  1   ˜ FIG.  7    regarding a device implementable on a firearm  300 , which may be an AR-style firearm or an AK-style firearm. The device may include a handguard  110  configured to at least partially surround a barrel  310  of the firearm  300  when the handguard  100  is installed on the firearm  300 . It is noteworthy that, although a different design is shown in each of  FIG.  2   ˜ FIG.  6   , in some implementations some or all of the designs may be implemented in one handguard. In other words, in some implementations, two or more of the different designs may be implemented in a single handguard in accordance with the present disclosure, while in some other implementations, one of the different designs may be implemented in a single handguard in accordance with the present disclosure. Therefore, although each of  FIG.  2   ˜ FIG.  6    shows a respective design, the feasibility of multiple ones of the different designs being implemented in a single handguard is not precluded or otherwise excluded. 
     Referring to  FIG.  1   , handguard  100  may include at least a lower handguard portion  110  configured to at least partially surround a barrel  310  of the firearm  300  when the handguard  100  is installed on the firearm  300 . The lower handguard portion  110  may include at least first physical feature  112  and second physical feature  114 A/ 114 B such that: (a) the first physical feature  112  is configured to accommodate mounting of an accessory  200  of the firearm  300  on the handguard  100 , and (b) the second physical feature  114 A/ 114 B is configured to secure a cable  210  of the accessory  200  onto the handguard  100 . 
     In some implementations, the first physical feature  112  may include one or more slots or openings. Alternatively, or additionally, the first physical feature  112  may include an interface system such as, for example and without limitation, a Modular Lock (M-LOK) interface system, a KeyMod interface system, a Picatinny rail, a Weaver rail, or any combination thereof. 
     In some implementations, the second physical feature  114 A/ 114 B may include: (i) at least one notch  114 A on an edge  115  and/or  117  of one or more walls of the lower handguard portion  110  (as shown in  FIG.  1   ˜ FIG.  5   ) or at least one opening  114 A on the wall of the handguard  100  (as shown in  FIG.  6   , formed by corresponding notches on the upper handguard portion  120  and the lower handguard portion  110 ), and (ii) a protrusion  114 B with at least one indentation and disposed on an interior surface of the lower handguard portion  110  such that a portion of the cable  210  may be secured by the second physical feature (e.g., by being stuffed in and squeezed by the at least one indentation of the protrusion  114 B). 
     In some implementations, the handguard  100  may be a monolithic handguard (e.g., made of polymer by injection molding) having the first physical feature  112  and the second physical feature  114 A/ 114 B. 
     Referring to  FIG.  2   , the first physical feature  112  may be configured to accommodate the mounting of the accessory  200  on a first primary surface of the handguard  100 . Moreover, the second physical feature  114 A/ 114 B may be configured to secure at least one portion of the cable  210  of the accessory  200  onto a second primary surface of the handguard  100  different from the first primary surface, thereby allowing a user of the firearm  300  to turn on and off the accessory  200  by activating and deactivating a switch  220  of the accessory  200 . The second primary surface may be opposite the first primary surface. For instance, the first primary surface may include an exterior surface of the handguard  100  (e.g., an exterior surface of lower handguard portion  110 ). Correspondingly, the second primary surface may include an interior surface of the handguard  100  (e.g., an interior surface of lower handguard portion  110 ) facing the barrel  310  of the firearm  300  when the handguard  100  is installed on the firearm  300 . 
     In the design shown in  FIG.  2   , the protrusion  114 B may include a ridge-shaped protrusion extending along a direction parallel to a longitudinal axis  315  of the barrel  310 .

The second primary surface may be opposite the first primary surface. For instance, the first primary surface may include an exterior surface of the handguard  100  (e.g., an exterior surface of lower handguard portion  110 ). Correspondingly, the second primary surface may include an interior surface of the handguard  100  (e.g., an interior surface of lower handguard portion  110 ) facing the barrel  310  of the firearm  300  when the handguard  100  is installed on the firearm  300 . 
     In the design shown in  FIG.  3   , the protrusion  114 B may include a ridge-shaped protrusion extending along a direction perpendicular to a longitudinal axis  315  of the barrel  310 . In this design, the protrusion  114 B may protrude upwardly from a bottom interior surface of the lower handguard portion  110 . Accordingly, at least one portion of the cable  210  of the accessory  200  may enter a space between the handguard  100  and the barrel  310  of the firearm  300  through the at least one notch  114 A on the wall  115 / 117  of the handguard  100  so that the at least one portion of the cable  210  may be secured by the at least one indentation on the protrusion  114 B. 
     In the design shown in  FIG.  3   , an opening formed by the at least one indentation may face upward with respect to the firearm  300  when the handguard  100  is installed on the firearm  300  such that the at least one portion of the cable  210  is inserted into or removed from the opening formed by the at least one indentation by a downward or upward movement with respect to the firearm  300 , respectively. 
     Referring to  FIG.  4   , the first physical feature  112  may be configured to accommodate the mounting of the accessory  200  on a first primary surface of the handguard  100 . Moreover, the second physical feature  114 A/ 114 B may be configured to secure at least one portion of the cable  210  of the accessory  200  onto a second primary surface of the handguard  100  different from the first primary surface, thereby allowing a user of the firearm  300  to turn on and off the accessory  200  by activating and deactivating a switch  220  of the accessory  200 . The second primary surface may be opposite the first primary surface. For instance, the first primary surface may include an exterior surface of the handguard  100  (e.g., an exterior surface of lower handguard portion  110 ). Correspondingly, the second primary surface may include an interior surface of the handguard  100  (e.g., an interior surface of lower handguard portion  110 ) facing the barrel  310  of the firearm  300  when the handguard  100  is installed on the firearm  300 . 
     In the design shown in  FIG.  4   , the protrusion  114 B may include a ridge-shaped protrusion extending along a direction perpendicular to a longitudinal axis  315  of the barrel  310 . Accordingly, at least one portion of the cable  210  of the accessory  200  may enter a space between the handguard  100  and the barrel  310  of the firearm  300  through the at least one notch  114 A on the wall  115 / 117  of the handguard  100  so that the at least one portion of the cable  210  may be secured by the at least one indentation on the protrusion  114 B. 
     In the design shown in  FIG.  4   , an opening formed by the at least one indentation may face left or right with respect to the firearm  300  when the handguard  100  is installed on the firearm  300  such that the at least one portion of the cable  210  is inserted into or removed from the opening formed by the at least one indentation by a rightward or leftward movement with respect to the firearm  300 , respectively.

The second primary surface may be opposite the first primary surface. For instance, the first primary surface may include an exterior surface of the handguard  100  (e.g., an exterior surface of lower handguard portion  110 ). Correspondingly, the second primary surface may include an interior surface of the handguard  100  (e.g., an interior surface of lower handguard portion  110 ) facing the barrel  310  of the firearm  300  when the handguard  100  is installed on the firearm  300 . 
     In the design shown in  FIG.  5   , the protrusion  1148  may include a ridge-shaped protrusion extending along a direction perpendicular to a longitudinal axis  315  of the barrel  310 .

     Additional Notes 
     The herein-described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected”, or “operably coupled”, to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable”, to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components and/or logically interacting and/or logically interactable components. 
     Further, with respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity. 
     Moreover, it will be understood by those skilled in the art that, in general, terms used herein, and especially in the appended claims, e.g., bodies of the appended claims, are generally intended as “open” terms, e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to implementations containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an,” e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more;” the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number, e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations. Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc. In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc. It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.” 
     From the foregoing, it will be appreciated that various implementations of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. Accordingly, the various implementations disclosed herein are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
