The present disclosure generally relates to two-part buckles that include a male component snapped into a female component, and more particularly to a buckle with improved alignment features.
Two-piece buckles that snap together and latch automatically upon adequately inserting a male component into a female component are known and used in a variety of applications. A piece of webbing or strap can be attached to each of the components, and one or both buckle components can be adjustably retained on the strap or webbing. It is also known to have both components in fixed locations relative to a strap or web that is sewn or otherwise fixedly secured to the buckle component. Such buckles are known and used for a variety of applications, including outdoor recreational products like backpacks, bike helmets and life vests and other equipment. Two-part buckles are used also on luggage, bags, clothing and the like.
In order to properly assemble a two-piece buckle, the male and female components need to be aligned. However, in practical use the male and female components are often not aligned properly. It would therefore be highly desirable to provide a buckle assembly with progressive alignment features.
The present disclosure generally relates to two-part buckles that include a male component snapped into a female component, and more particularly to a buckle with improved alignment features, substantially as illustrated by and described in connection with at least one of the figures, as set forth more completely in the claims.
The foregoing and other objects, features, and advantages of the devices, systems, and methods described herein will be apparent from the following description of particular examples thereof, as illustrated in the accompanying figures; where like or similar reference numbers refer to like or similar structures. The figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the devices, systems, and methods described herein.
References to items in the singular should be understood to include items in the plural, and vice versa, unless explicitly stated otherwise or clear from the text. Grammatical conjunctions are intended to express any and all disjunctive and conjunctive combinations of conjoined clauses, sentences, words, and the like, unless otherwise stated or clear from the context. Recitation of ranges of values herein are not intended to be limiting, referring instead individually to any and all values falling within and/or including the range, unless otherwise indicated herein, and each separate value within such a range is incorporated into the specification as if it were individually recited herein. In the following description, it is understood that terms such as “first,” “second,” “top,” “bottom,” “side,” “front,” “back,” and the like are words of convenience and are not to be construed as limiting terms. For example, while in some examples a first side is located adjacent or near a second side, the terms “first side” and “second side” do not imply any specific order in which the sides are ordered.
The terms “about,” “approximately,” “substantially,” or the like, when accompanying a numerical value, are to be construed as indicating a deviation as would be appreciated by one of ordinary skill in the art to operate satisfactorily for an intended purpose. Ranges of values and/or numeric values are provided herein as examples only, and do not constitute a limitation on the scope of the disclosure. The use of any and all examples, or exemplary language (“e.g.,” “such as,” or the like) provided herein, is intended merely to better illuminate the disclosed examples and does not pose a limitation on the scope of the disclosure. The terms “e.g.,” and “for example” set off lists of one or more non-limiting examples, instances, or illustrations. No language in the specification should be construed as indicating any unclaimed element as essential to the practice of the disclosed examples.
The term “and/or” means any one or more of the items in the list joined by “and/or.” As an example, “x and/or y” means any element of the three-element set {(x), (y), (x, y)}. In other words, “x and/or y” means “one or both of x and y”. As another example, “x, y, and/or z” means any element of the seven-element set {(x), (y), (z), (x, y), (x, z), (y, z), (x, y, z)}. In other words, “x, y, and/or z” means “one or more of x, y, and z.”
A buckle assembly can be used to join two or more components, such as a lead (e.g., straps, ropes, strips, cordage, or another material to be fastened). Such buckles may have various uses in different applications. For example, a buckle assembly may be used on bags, safety gear (e.g., helmets), collars, or any other application that may need to be fastened.
In one example, a female buckle component is configured to mate with a male buckle component into a securely connected position, where the female buckle component comprises: a housing that comprises a first side and a second side separated by a central rib, wherein each side of the housing defines: a button aperture configured to secure the button of a male buckle component; and a pocket configured to receive the male buckle component, wherein the pocket comprises an alignment edge at an opening of the pocket.
In some examples, the alignment edge may be configured to align a male buckle component to be parallel with the female buckle component. The alignment edge may define a chamfered edge. The chamfered edge may be configured to extend away from a central plane that extends perpendicular to the central rib. In some examples, the angle of the chamfered edge may be less than about 90° relative to the central plane. In other examples, the angle of the chamfered edge may be about 35° relative to the central plane.
In some examples, each side of the housing comprises one or more locking ledges configured to receive one or more locking tips of a male buckle component.
In another example, a buckle assembly comprises: a female buckle component configured to mate with a male buckle component into a securely connected position, said female buckle component comprising a housing comprising a first side and a second side separated by a central rib, wherein each side of the housing defines: a button aperture configured to secure the button of a male buckle component; a pocket; and one or more locking ledges; the male buckle component configured to mate with the female buckle component, the male buckle component comprising: a main body; a first guide bar and a second guide bar coupled to the main body; and a first lateral arm and a second lateral arm coupled to the main body and configured to deflect about a pivot point, each of the first lateral arm and the second lateral arms comprising: a flexible lateral arm; a button; one or more locking tips configured to engage the one or more locking ledges of the female buckle component; and a guide fin.
In some examples, the relative positions of the guide fins and guide bars are configured to align the male buckle component with the female buckle component. The distal end of the first guide fin and the distal tip of the first guide bar may be positioned to define a first gap and the distal tip of the second guide fin and the distal tip of the second guide bar may be positioned to define a second gap, wherein each gap is smaller than the width of the central rib of the female buckle component. The first guide bar and the second guide bar can be positioned to define a space that is configured to engage with the central rib of the female buckle component. The width of the space space defined by the first guide bar and the second guide bar can be equal to or greater than the width of the central rib of the female buckle component. In some examples, the width of the space defined by the first guide bar and the second guide bar is greater than the width of the central rib of the female buckle component.
In some examples, the first and second gaps enable the progressive guidance of the central rib of the female buckle component into the space defined by the first guide bar and the second guide bar.
In some examples, each lateral arm comprises two locking tips. The distal tip of the first guide fin and the distal tip of the first guide bar can be sized and positioned to define a first clearance and the distal tip of the second guide fin and the distal tip of the second guide bar are positioned to define a second clearance. In further examples, the first and second clearance enable the one or more locking tips to disengage the one or more locking tips from the one or more locking ledges of the female buckle component.
Leads 122 can be attached to each of the male buckle component 104 and the female buckle component 102 so that buckle assembly 100 can be used to secure together opposite ends of a single lead 122 or to secure ends of separate leads 122. Example leads 122 include, inter alia, straps (e.g., backpack straps, belts, etc.), ropes, strips, cordage, or another material to be fastened. The leads 122 may be fabricated from, for example, plastic, nylon, leather, fabric, etc. In some examples, each of the male buckle component 104 and the female buckle component 102 may be adjustably positioned along the length of a lead 122. Other structures, or components, however, may be used to couple to the male buckle component 104 and/or the female buckle component 102 in addition to, or in lieu of, the leads 122. For example, the male buckle component 104 and/or the female buckle component 102 may be coupled to an item (e.g., bag, belt, garment, etc.) via mechanical fasteners (e.g., snaps, rivets, carabiner clips, etc.), adhesives, etc.
In order to securely mate the male buckle component 104 into the female buckle component 102, the male buckle component 104 is urged into the female buckle component 102 via insertion force 154. The female buckle component 102 defines a receiving body or pocket 128. In some examples, the female buckle component 102 includes a housing 114 formed as a set of plates spaced apart and secured at the edges via the sides 144 to form a pocket-like structure to define the pocket 128. The sides 144 of the housing 114 are shaped to define button apertures 140 (e.g., apertures in the sides 144). The button apertures 140 are sized and positioned to receive buttons 106 when the male buckle component 104 is fully inserted into the pocket 128 of the female buckle component 102. The pocket 128 may further define one or more channels to define a guide way to direct male buckle component 104 straight into female buckle component 102 from an entrance opening 128a to the pocket 128. The one or more channels may be formed on, for example, the interior surface of the set of plates 146. The one or more channels may be defined by a central rib 150 that extends across the length of the female buckle component 102.
The one or more channels may be configured to guide the male buckle component 104 via one or more guide bars 138 that outwardly extend from a rigid strut member 108. To this end, a pair of guide bars may be positioned to define a space 162 that is configured to engage with the central rib 150 of the female buckle component 102. For example, using insertion force 154 as indicated by Arrow B, the guide bars 138 pass into a mating channel or sleeve formed in the female buckle component in order to assure proper mating alignment. Once the buttons 106 are snapably secured into the button apertures 140 in the female buckle component 102 (e.g., via engagement of one or more locking tips 106a of male buckle component 104 with one or more locking ledges 148 of female buckle component 102), the male buckle component 104 is securely retained within the female buckle component 102.
The housing 114 further includes one or more locking ledges 148 to interface with the male buckle component 104. For example, an edge of each button aperture 140 nearest the entrance opening 128a to the pocket 128 may define the locking ledge 148 or be provided another form of pediment. The locking ledges 148 may interface with the male buckle component 104 via engagement with locking tips 106a of the female buckle component 102. For example, one or more lateral arm members 116 may outwardly extend from rigid strut member 108. Each lateral arm member 116 may comprise one or more locking tips 106a. The locking tips 106a may, in some examples, form a portion of the button 106. In other examples, the locking tips 106a may comprise distinct components. In some examples, each lateral arm member 116 may comprise a single locking tip 106a. In other examples, each lateral arm member 116 may comprise two locking tips 106a (e.g., one locking tip 106a located on each face of the lateral arm member 116.) Using insertion force 154 as indicated by Arrow B, the locking tips 106a of the male buckle component 104 are engaged with the locking ledges 148 of female buckle component 102 to form a securely connected position.
As described above, the male buckle component 104 includes a pair of lateral arm members 116. While the pair of lateral arm members 116 are illustrated as generally parallel to one another, they may be non-parallel. Each of the lateral arm members 116 includes a flexible lateral arm 112 with a button 106 at a distal end 118 thereof. The distal end 118 of each of the lateral arm members 116 further includes a guide fin 132. As illustrated, the flexible lateral arms 112 are spaced apart and may be generally parallel to one another. In some examples, the flexible lateral arms 112, the buttons 106, and the guide fins 132 are fabricated as a unitary structure. In other examples, the flexible lateral arms 112, the buttons 106, and the guide fins 132 are distinct components. For example, the buttons 106 may be a solid rigid button coupled to an end of the flexible lateral arm 112 and the guide fins 132 may be a solid rigid guide fin coupled to an end of the button 106. In other examples, the flexible lateral arm 112 may be configured to form a non-linear portion that defines, or otherwise serves as, the button 106. For example, the flexible lateral arm 112 may shaped to define the button 106. Similarly, the flexible lateral arm 112 (or the button 106) may also be configured to form a non-linear portion that defines, or otherwise serves as, the guide fin 132. In any arrangement, the lateral arm members 116 (or buttons 106) further comprise a locking tip 106a to engage the female buckle component 102. For example, the locking tip 106a may engage a locking ledge 148 defined by the housing 114 of the female buckle component 102. In some examples, the locking tips 106a may be a distinct component (e.g., the locking tips 106a may be a rigid coupled to the end of the button 106). In other examples, the button 106 (or flexible lateral arm 112) may be configured to form a portion that defines, or otherwise serves as, the locking tips 106a.
In some examples, the rigid strut member 108 extends between the lateral arm members 116. The rigid strut member 108 is generally perpendicular to the lateral arm members 116. A lead-receiving channel 120 is formed through the male buckle component 104 between, for example, the rigid strut member 108 and a lead bar 110. In some examples, the rigid strut member 108 and the lead bar 110 are parallel to one another. The lead-receiving channel 120 is configured to secure the lead 122. The lateral arm members 116 are integrally connected to the main body 126 at pivot points 124 (e.g., via the rigid strut member 108). The lateral arm members 116 are configured to pivot (e.g., flex) in the direction of arcs A and A′ about pivot points 124 defined by the union of the rigid strut member 108 and the lateral arm members 116. In other words, the lateral arm members 116 are rigidly coupled at pivot points 124 and configured to flex inwardly along its length (e.g., its effective length 130) in the direction of arcs A and A′.
In general, the rigid strut member 108 is disposed between the pivot points 124 and adjacent the lead-receiving channel 120. In one example, the pivot points 124 are proximate the rigid strut member 108 of the main body 126. As such the pivot points 124 are distally located from the lead bar 110 and the rigid strut member 108. As shown in
In operation, the pair of lateral arm members 116 is inserted into and received by the pocket 128 of female buckle component 102 as indicated by Arrow B to latch the buckle assembly 100. As described above, a pair of guide bars 138 may be positioned to define a space 162 that is configured to engage with the central rib 150 of the female buckle component 102. In order to secure the male buckle component 104 into the female buckle component 102, the male buckle component 104 is urged into the female buckle component 102 in the direction of Arrow B. The space 162 defined by the guide bars 138, upon insertion force 154, may move to engage with the central rib 150 to ensure proper mating alignment between the female and male buckle components 102 and 104, respectively.
As the male buckle component 104 is urged into the female buckle component 102, the lateral arm members 116 deflect outwardly (e.g., deformed or flexed) in the opposite directions of Arrows A and A′ until the buttons 106 reach button apertures 140 formed by the female buckle component 102. To that end, the flexible lateral arm 112 is configured to flex along its effective length 130 between the pivot point 124 and the distal end 118 of the flexible lateral arm 112 during connecting and disconnecting of the buckle assembly 100. The effective length 130 is a function of the shape of the flexible lateral arm 112. For purposes of this disclosure, the effective length 130 refers to the length along the flexible lateral arm 112 to enable the flexible lateral arm 112 to flex between the pivot point 124 and the distal end 118 of the flexible lateral arm. In the example of
In operation, the male buckle component 104 and the female buckle component 102 need to be properly aligned from a top view in order to form a securely connected buckle assembly 100. More specifically, the central rib 150 of the female buckle component 102 needs to rest between the guide bars 138, while still allowing the flexible lateral arms 112 to flex and initiate release of the buckle assembly 100.
In order to ensure proper alignment of the male buckle component 104 and the female buckle component 102 from a top view, the guide fins 132 can be configured to progressively guide the space 162 defined by the guide bars 138 of the male buckle component 104 around the central rib 150 female buckle component 102 as the male buckle component 104 is urged into the female buckle component 102 via insertion force 154. To that end, the shape of the guide fins 132 may be configured to aid in the progressive guidance (e.g., the guide fins 132 may comprise a curved edge 132b that aids in progressive guidance and alignment). Further, the relative sizes and positions of the guide fins 132 and the guide bars 138 can be configured to progressively align the space 162 with the central rib 150 during assembly. For example, the guide fins 132 and guide bars 138 can be sized and positioned such that the distal tip 132a of a guide fin 132 and the distal tip 138a of a guide bar 138 define a gap 164 that has a size that is less than the width W3 of the central rib 150.
As described above, the buckle assembly is 100 is released or disconnected by providing compression forces 152 inwardly from the side as indicated by Arrows A and A′.
As shown in
In some examples, the housing 114 of the female buckle component 102 includes one or more locking ledges 148 to interface with the male buckle component 104. For example, the housing 114 may define the locking ledge 148 at or near the proximal end 140a of the button aperture 140. In other examples, the locking ledge 148 may be located on a different part of the housing 114.
Secure mating of the male buckle component 104 into the female buckle component 102 requires the male buckle component 104 and the female buckle component 102 to be parallel to each other and in the same plane. However, in operation, the male buckle component 104 is often not aligned to be perfectly parallel and in the same plane as the female buckle component 102. Thus, female buckle component 102 may include one or more alignment edges 156 defined by the housing 114 that can be configured to align the male buckle component 104 to be parallel with female buckle component 102 during connection of buckle assembly 100. To that end, the alignment edges 156 may be configured to progressively align the male buckle component 104 to be parallel and in the same plane with female buckle component 102 as the male buckle component 104 is urged into the female buckle component 102 via insertion force 154 (e.g., in a situation where the male and female components are not parallel and in the same plane upon initiation of insertion force 154). As the male buckle 104 is inserted into female buckle component 102 at non-parallel angle with respect to a central plane that extends perpendicular to central rib 150, the alignment edges 156 can progressively adjust the angle of the of the male buckle component during assembly (i.e., as insertion force 154 urges the male and female components together) such that the male and female buckle components are parallel and in the same plane with one another.
In certain examples, each alignment edge 156 defines a chamfered edge 160. The chamfered edges 160 may extend from the proximal end 140a of the button aperture 140 to the entrance opening 128a to the pocket 128. In some examples, the chamfered edge 160 may extend from the proximal end 140a of a button aperture 140 and extend around a corner (or rounded corner) to a central rib 150 that bisects a first side of the female buckle component 102 from a second side of female buckle component 102. The female buckle component 102 may contain a pair of chamfered edges 160 spaced apart to define a height H2 (e.g., measured in the direction parallel to central rib 150). The chamfered edges 160 are sloped or angled edges that are configured to slope or angle away from a central plane that extends perpendicular to the central rib 150. The angle of one or more of the chamfered edges 160 may be less than 90°, less than 75°, less than or less than 25° relative to the central plane. In some examples, the angle of each chamfered edge 160 is 35° relative to the central plane. In some examples, each chamfered edge 160 may be the same angle relative to the central plane. In other examples, each chamfered edge 160 may comprise a different angle relative to the central plane.
In operation, chamfered edges 160 can provide an alignment effect as described above (i.e., facilitating the alignment of male buckle component 104 to be parallel with female buckle component 102 during connection of buckle assembly 100). To this end, as the male buckle component 104 is urged into the female buckle component 102 using insertion force 154, the locking tips 106a can interact with the chamfered edges 160 to provide an aligning effect.
