## Background
RELATED APPLICATIONS
This application claims priority to U.S. Provisional Application No. 62/028,899, filed on Jul. 25, 2014, the entire contents of which are incorporated herein by reference.


BACKGROUND
Conventional guitar strap connectors typically consist of an opening punched into the end of a strap. The opening may be forced over a standard guitar strap button, relying on the stiffness of the strap connector material, such as leather, to keep the strap from accidentally slipping off the button. Under heavy or repeated use, the stiffness of the strap connector material may lessen and the strap connector may fail, resulting in possible damage to the instrument.
Some guitar strap connectors have addressed this problem by reinforcing the opening, but these guitar strap connectors may still fail when the button accidentally slides into a wider section of the opening. Further, still other guitar strap connectors have attempted to prevent this sliding by physically blocking off the wider part of the opening after the connector engages with the button. However, since multiple styles of buttons exist, users may be forced to purchase a separate connector for each button style. Moreover, some of these blocking mechanisms may be bulky and unattractive.
SUMMARY OF THE INVENTION
This disclosure generally pertains to various end pieces for releasably securing to a coupling element. The end pieces described herein can include a body configured to securely attach to a first coupling element, such as a button. In some examples, the body can be configured to securely attach to a separate element, such as a strap. In at least one example, the end piece may be used for releasably securing a guitar strap to one or more buttons on an instrument, such as a guitar.

DETAILED DESCRIPTION
Overview
This disclosure generally pertains to various end pieces for releasably securing to a coupling element and various methods for using the end pieces. In various examples, the end piece can include a body. The body can include a first aperture with multiple flexible projection elements and a second aperture. In some examples, the first aperture and the second aperture can be separated by one or more catch elements (e.g., tab, flexible protrusions, etc.). In such examples, the one or more catch elements can define an opening for the second aperture.
Additionally, the body can include a linking member. The linking member can enable a connection between the end piece and a separate element. For example, the linking member can comprise an elongated pass-through shaped to fit an end of a strap, thereby enabling the connection of the strap to the end piece. In at least one example, the end pieces may be used for releasably securing a strap to one or more coupling elements on an instrument, such as a guitar.
In various examples, the body can comprise an outer body and an inner body. In some examples, the outer body and the inner body may be arranged directly adjacent to one another, and may comprise different materials. In other examples, the outer body and the inner body may comprise the same materials. In at least one example, the outer body may be over-molded to the inner body.
Following the “Overview,” the disclosure continues with a section entitled “Example Environment,” which describes non-limiting examples of an environment in which the end pieces may be used. After the environment discussion, the disclosure continues with a section entitled “Example End Pieces,” which describes non-limiting examples of releasably securable end pieces. Finally, the discussion ends with a “Conclusion.”
This brief overview, including section titles and corresponding descriptions, is provided for the reader's convenience and is not intended to limit the scope of the claims. The features of the described end pieces and corresponding methods may be implemented in any number of forms. The example end pieces and corresponding methods described herein are merely illustrative. The implementations described herein are not mutually exclusive and aspects of the various implementations may be combined to arrive at other implementations within the scope of the claims. The features, functions, and advantages that have been discussed above and/or will be discussed below are merely examples that may, but need not necessarily, be achieved by releasably securable end pieces according to one or more implementations described herein. Further details of various example implementations are set forth below with reference to the following description and drawings.
Example Environment
FIG. 1 is a perspective view of an example environment 100 in which an end piece 102 can be used. In various examples, an end piece 102 can be configured to securely attach to a first coupling element 104. As shown in FIG. 1, the first coupling element 104 can include a button. In other examples, the first coupling element 104 can include a hook, a magnet, or another type of coupling element.
As illustrated in FIG. 1, two end pieces 102 can be securely attached to a guitar 106, each releasably securing to a respective first coupling element 104 (e.g., a button on the guitar). The end pieces 102 can include a linking member 108 to securely attach the end piece 102 to a separate element 110 (e.g., a strap). In some examples, two or more linking members 108 on the end pieces 102 can couple to the same coupling element, such as a strap (e.g., two or more end pieces can operate together as a kit). In other examples, the linking members 108 on the end pieces 102 can couple to respective separate elements 110. For example, a potted plant may hang from two separate coupling elements, each securely attached to an end piece on opposite sides of the potted plant.
In some examples, a greater or fewer number of end pieces can be securely attached to an object. In other examples, two or more end pieces 102 can be used to securely attach to multiple objects, such as, for example, to connect multiple objects together. For example, two end pieces can be securely attached to a guitar, and a third securely attached to a bag for carrying sheet music.
In the illustrative example, the end pieces 102 can releasably secure to the first coupling elements 104 at a first end and a second end of the guitar 106. In various examples, the end pieces 102 can releasably secure to first coupling elements 104 located at various other places on the guitar. As an illustrative example, the first end section 112 will be explained in greater detail with respect to FIGS. 2A and 2B. However, it is understood that the first end section 112 and a second end section can be substantially similar.
FIGS. 2A and 2B are perspective views of an illustrative method 202 of securing an end piece 202 to an object. FIG. 2A depicts the end piece 200 in a first position. FIG. 2B depicts the end piece 202 in a second position.
As depicted in FIGS. 2A and 2B, the end piece 202 can include a body 204. In various examples, the body 204 can be manufactured via traditional manufacturing techniques. In some examples, the body 204 can be manufactured by 3-D manufacturing techniques, printing, press molding, injection molding, fabrication, machining, over-molding, composite manufacturing, or another method of manufacturing. The body 204 can comprise a single piece, or it can be assembled from two or more pieces. In at least one example, the body 204 can be manufactured by over-molding an outer body to an inner body.
The body 204 can be formed from any of a wide variety of materials, including substantially inflexible materials, resiliently flexible materials, or the like, or combinations thereof. By way of non-limiting examples, the material can include: elastomer, elastomer-like material, rubber, rubber-like material, plastic, plastic-like material, acrylic, polyamide, polyester, polypropylene, polyvinyl chloride-based materials, silicone-based materials, or the like, or combinations thereof.
In various examples, the body 204 can be formed from a material which precludes the body 204 from damaging a surface which the body 204 disposes adjacent to, such as guitar 206. For example, the material can preclude the body 204 from scratching the guitar 206. Additionally, the material can preclude the body 204 from engaging with the guitar 206 so as to generate an undesirable sound, such as a rattling sound or clanking sound.
In various examples, the body 204 may include a resistance or frictional surface and/or material on a bottom side between the body 204 and the guitar 206. The frictional surface and/or material may prevent the body 204 from moving in relation to the guitar 206 without a threshold force applied by a user, for example. In some examples, the frictional surface and/or material may be connected to or manufactured with the body 204. In some examples, the frictional surface and/or material may be a separate component, placed on a bottom side of the body 204.
Examples of the frictional material can include rubber, polyurethane, nylon, Teflon, silicone, polypropylene, acrylonitrile butadiene styrene (ABS), polyethylene or the like. Frictional material can be chosen to have a desired static and/or kinetic frictional properties based on desired resistance to movement (i.e., the desired threshold force that must be applied by the user to move the end piece relative to the coupling element of the guitar).
In various examples, the body 204 can comprise a linking member 208. The linking member 208 can comprise a hole, a slot, or another type of pass-through. The linking member 208 can be substantially rectangular, ovular, circular, square, or another shape capable of housing the separate element 210. The separate element 210 can include a strap, webbing, rope, twine, or another material used for securing equipment. For example, a strap can be fed though the linking members of two end pieces to create a carrying strap for a guitar (110 of FIG. 1).
In various examples, the body 204 can include a first aperture (304 in FIG. 3) with multiple flexible projection elements 212 (FIG. 2B) and a second aperture (306 in FIG. 3). In some examples, the first aperture and the second aperture can be separated by one or more catch elements 214 (e.g., tab, flexible protrusions, etc.).
As shown in FIG. 2A, the first aperture can define any of a wide variety of numerous configurations which can be capable of insertingly receiving any of a corresponding wide variety of numerous configurations of coupling elements, such as coupling element 216. By way of non-limiting examples, the first aperture can define a circle, an oval, an ellipse, a triangle, a square, a rectangle, a trapezoid, a polygon, or the like, or combinations thereof. As an illustrative example, the first aperture can define a circle, which can insertingly receive a substantially circular coupling element 216 coupled to the guitar 206.
As to particular embodiments including a first aperture which defines a circle capable of insertingly receiving a substantially circular coupling element 216 coupled to the guitar 206, the first aperture can have dimensions capable of receiving coupling elements 216 having a wide variety of dimensions. In at least one example, a particular embodiment of the body piece 204 can include a resiliently flexible first aperture defining a circle having a diameter of about 20 millimeters. Accordingly, the resiliently flexible first aperture can insertingly receive substantially circular coupling elements 216 having diameters ranging from between about 5 millimeters to about 25 millimeters.
As shown in FIG. 2A, the first aperture can insertingly receive the coupling element 216 in a first position. The end piece 200 can be adjusted in such a way that the coupling element 216 can be moved from the first position in the first aperture to a second position in the second aperture depicted in FIG. 2B.
In various examples, the first aperture and the second aperture can be separated by two or more catch elements 214. In such examples, the two or more catch elements 24 can define an opening for the second aperture. As illustrated in FIGS. 2A and 2B, the catch elements 214 can be substantially horizontal pieces extending inward from the body 204. In some examples, the catch elements 214 can be implements that extend in a substantially vertical direction (618 in FIG. 6). The catch elements 214 can be formed of a same material as the body 204. In some examples, the catch elements 214 can be formed of a different material. In such examples, the catch elements 214 can be a part of the inner body.
In various examples, the catch elements 214 can provide a locking mechanism to firmly secure the coupling element 216 in the second position shown in FIG. 2B. In such examples, the catch elements 214 may require a threshold amount of lateral force applied to move the coupling element 216 from the second position to the first position. In at least one example, the threshold amount of lateral force can be between 5-15 pounds (lbs) of force.

In various examples, coupling element can be insertingly received by the first aperture 304 having the plurality of projection elements 310. In such examples, the coupling element can slightly displace the plurality of projection elements 310 during insertion. Responsive to a top end of the coupling element passing through the first aperture 304, the plurality of projection elements 310 can return to the stationary position. In some examples, the plurality of projection elements 310 can act as a locking mechanism, requiring a threshold amount of vertical force (e.g., force perpendicular to the end piece) to release the coupling element from the first aperture 304. In some examples, the threshold amount of vertical force may be in a range of about 5-20 lbs of force.

Conclusion
Although implementations have been described in language specific to structural feature, it is to be understood that the disclosure is not necessarily limited to the specific features or acts described. Rather, the specific features and acts are disclosed as illustrative forms of employing the implementations. For example, in various implementations, any of the structural features and/or methodological acts described herein may be rearranged, modified, or omitted entirely.
The particular embodiments or elements of the invention disclosed by the description or shown in the figures or tables accompanying this application are not intended to be limiting, but rather exemplary of the numerous and varied embodiments generically encompassed by the invention or equivalents encompassed with respect to any particular element thereof. In addition, the specific description of a single embodiment or element of the invention may not explicitly describe all embodiments or elements possible; many alternatives are implicitly disclosed by the description and figures.
It should be understood that each element of an apparatus or each step of a method may be described by an apparatus term or method term. Such terms can be substituted where desired to make explicit the implicitly broad coverage to which this invention is entitled. As but one example, it should be understood that all steps of a method may be disclosed as an action, a means for taking that action, or as an element which causes that action. Similarly, each element of an apparatus may be disclosed as the physical element or the action which the physical element facilitates. As but one example, the disclosure of a “coupling” should be understood to encompass disclosure of the act of “coupling”—whether explicitly discussed or not—and, conversely, were there effectively disclosure of the act of “coupling”, such a disclosure should be understood to encompass disclosure of a “coupling” and even a “means for coupling.” Such alternative terms for each element or step are to be understood to be explicitly included in the description.
In addition, as to each term used it should be understood that unless its utilization in this application is inconsistent with such interpretation, common dictionary definitions should be understood to be included in the description for each term as contained in the Random House Webster's Unabridged Dictionary, second edition, each definition hereby incorporated by reference.
All numeric values herein are assumed to be modified by the term “about”, whether or not explicitly indicated. For the purposes of the present invention, ranges may be expressed as from “about” one particular value to “about” another particular value. When such a range is expressed, another embodiment includes from the one particular value to the other particular value. The recitation of numerical ranges by endpoints includes all the numeric values subsumed within that range. A numerical range of one to five includes for example the numeric values 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, and so forth. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. When a value is expressed as an approximation by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. The term “about” generally refers to a range of numeric values that one of skill in the art would consider equivalent to the recited numeric value or having the same function or result. Similarly, the antecedent “substantially” means largely, but not wholly, the same form, manner or degree and the particular element will have a range of configurations as a person of ordinary skill in the art would consider as having the same function or result. When a particular element is expressed as an approximation by use of the antecedent “substantially,” it will be understood that the particular element forms another embodiment.
Moreover, for the purposes of the present invention, the term “a” or “an” entity refers to one or more of that entity unless otherwise limited. As such, the terms “a” or “an”, “one or more” and “at least one” can be used interchangeably herein.
