The present invention relates generally to fasteners for interconnecting straps, belts, ropes, chains, or the like.
Buckles, clasps, and similar fasteners come in numerous designs and employ many functional means for securing two ends of a strap together. Such fasteners are used to secure a wide variety of items including waist belts, watch bands, articles of jewelry, shoes, and suitcases. Some conventional fastening devices, such as frame and prong buckles, snap-fit buckles, and hook-and-eye clasps, continue to be widely used with modern consumer products. Despite this, current fastening devices continue to possess numerous shortcomings that have yet to be resolved.
“Frame and prong” buckles, which are commonly used to secure wrist watches and waist belts, have existed for thousands of years with relatively little change to their underlying design. Most frame and prong buckles are comprised of a rectangular frame and a prong pivotally mounted to the frame. One end of a belt is attached to the frame, while a second end of the belt is free. At the free end, one or more holes are formed through the belt material for receiving the prong. The free end of the belt may be secured to the other end by inserting it into the frame and pushing the prong through one of the holes, thereby forming a loop around a wearer's waist or wrist. While the frame and prong buckle serves its intended purpose, it is not without its shortcomings. Use of a belt and prong design necessarily requires there to be holes punched through the belt, causing irreparable damage to the belt material. Additionally, when the free end of the belt is secured through the frame, there is a portion of the belt that overlaps with itself, resulting in increased bulkiness along that portion. In turn, the increased bulkiness reduces the comfort to the user, damages aesthetic appearances by introducing asymmetry, and creates a protrusion that can snag on clothing or other items.
Other fastening devices have been developed to overcome the shortcomings associated with frame and prong buckles. For instance, some fastening devices provide a fastening component on both ends of a strap, thereby eliminating the need to force a prong through belt material. However, many of these fasteners comprise a male fastening component on one end and a differently configured female fastening component on the other end. For instance, snap-fit or side release buckles, which are commonly used to connect strapped items such as personal floatation jackets, safety harnesses, backpacks, and fanny-packs, are comprised of a male buckle component and a female buckle component. The male buckle component comprises a base, two prongs extending from the base, and a retaining block located on the distal end of each prong. The female buckle component is configured to receive the male buckle component and comprises a frame with a front opening and two side openings. When the male buckle component is inserted into the front opening of the female buckle component, the two retaining blocks fit into the side openings and lock the two components together. The two components may be disengaged by pushing the two retaining blocks together to unlock them from the side openings.
Despite their widespread use, side release buckles, and other similar fasteners that utilize male and female components, continue to present their own set of problems. For example, fastener designs that involve a female component and a counterpart male component necessarily require the male component to be configured differently to the female component. Consequently, the male and female components must be manufactured according to separate manufacturing processes, resulting in greater manufacturing expense and complexity. Furthermore, even when in an interlocked position, geometrical differences between the male and female components can introduce aesthetic asymmetries that negatively impact the aesthetic appearance of the fastener. Moreover, in order to be properly secured together, male and female fastening components must be oriented relative to one another such that the receiving portion correctly joins with the inserting portion. Accordingly, use of this type of fastening device requires manual alignment of the two components. As a result, users commonly encounter difficulties with securing the fastener when they need to secure it quickly or when they need to secure it without seeing it. Thus, there exists a need for a fastener that is easy to use, compact, comfortable, secure, and aesthetically symmetrical.
So as to reduce the complexity and length of the Detailed Specification, and to fully establish the state of the art in certain areas of technology, Applicant(s) herein expressly incorporate(s) by reference all of the following materials identified in each numbered paragraph below.

Aspects and applications of the invention presented here are described below in the drawings and detailed description of the invention. 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 inventor is fully aware that he can be his own lexicographer if desired. The inventor expressly elects, as his own lexicographer, to use only the plain and ordinary meaning of terms in the specification and claims unless he clearly states otherwise and then further, expressly sets forth the “special” definition of that term and explains how it differs from the plain and ordinary meaning. Absent such clear statements of intent to apply a “special” definition, it is the inventor's intent and desire that the simple, plain and ordinary meaning to the terms be applied to the interpretation of the specification and claims.
The inventor is 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 inventor is fully informed of the standards and application of the special provisions of 35 U.S.C. § 112(f). 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(f), to define the invention. To the contrary, if the provisions of 35 U.S.C. § 112(f) 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 inventor not to invoke the provisions of 35 U.S.C. § 112(f). Moreover, even if the provisions of 35 U.S.C. § 112(f) are invoked to define the claimed inventions, it is intended that the inventions 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 invention, or that are well known present or later-developed, equivalent structures, material or acts for performing the claimed function.

In the illustrated embodiment, the first elongated portion 110 forms a substantially cuboid shape and includes a first engagement surface 120, a first ridge 130, and a first magnet 140. The first engagement surface 120 is located on a surface of the first elongated portion 110 that is substantially perpendicular to both the exterior surface 126 and the contact surface 128. Protruding from the first elongated portion 110 is a first ridge 130 that extends along the entire length of the first engagement surface 120. The first ridge 130 has a substantially semi-circular cross-section and is disposed along the approximate middle-line of the first engagement surface 120. It is to be understood that in other embodiments the first ridge 130 may have a differently shaped cross-section, may be disposed along a different line of the first engagement surface 120, and may not extend the entire length of the first engagement surface 120. For instance, in another embodiment the first ridge 130 may have a cross-section that is rectangular, triangular, circular, or any other shape. The first ridge 130 may be disposed along any line that extends parallel to the length of the first engagement surface 120, including a line that is off-center from the midline, or a line that coincides with the outer edge of the first engagement surface 120. Additionally, the first ridge 130 may only extend along a fraction of the length of the first engagement surface 120.
In the illustrated embodiment, a first magnet 140 is embedded within the first elongated portion 110. The first magnet 140 is located proximal to the first engagement surface 120 and has a circular cross-section. The first magnet 140 may be a cylindrical magnet with a length that extends along the length of the first engagement surface 120. The first magnet 140 may be contained within a borehole 244 that is formed in the first elongated portion 110. The first magnet 140 may be coupled to the first elongated portion 110 by mechanical friction, adhesive, or any other means of fastening. In the illustrated embodiment, the first magnet 140 is diametrically magnetized, meaning that it is magnetized through the width of the magnet. The first magnet 140 is disposed within the borehole 244 such that one side of the magnet with a first polarity faces towards the first engagement surface 120 and the other side of the magnet with an opposite polarity faces away from the first engagement surface 120. The first magnet 140 may be made from any type of magnetized material such as neodymium iron boron, samarium cobalt, alnico, ceramic magnet, ferrite magnet, or the like. Additionally, it is to be understood that in other embodiments the first magnet 140 may be of any shape including, but not limited to, a cuboid, a triangular prism, a sphere, or the like. In other embodiments, the first magnet 140 may be affixed to an outer surface of the first elongated portion 110 rather than being embedded in the first elongated portion 110. Alternatively, the first elongated portion 110 itself may be made of a magnetized material.
In the illustrated embodiment, the second elongated portion 112 forms an approximately cuboid shape and includes a second engagement surface 122, a first attachment surface 124, a first groove 132, and a second magnet 142. The second engagement surface 122 is located on a surface of the second elongated portion 112 that is perpendicular to both the exterior surface 126 and the contact surface 128. The second engagement surface 122 is distal to and opposite from the first attachment surface 124. The first attachment surface 124 faces towards the first engagement surface 120. The first engagement surface 120, the first attachment surface 124, and the second engagement surface 122 are all surfaces that are substantially parallel to one another. In the illustrated example, the second elongated portion 112 is shorter than the first elongated portion 110. In other embodiments, the second elongated portion 112 may be longer than or the same length as the first elongated portion 110.
In the illustrated embodiment, a first groove 132 is disposed along the entire length the second engagement surface 122. The first groove 132 has a substantially semi-circular cross-section and is disposed along the approximate middle-line of second engagement surface 122. It is to be understood that in other embodiments the first groove 132 may have a differently shaped cross-section, may be disposed along a different line of the second engagement surface 122, and may not extend the entire length of the second engagement surface 122. For instance, in another embodiment the first groove 132 may have a cross-section that is rectangular, triangular, circular, or any other shape. The first groove 132 may be disposed along any line that extends parallel to the length of the second engagement surface 122, including a line that is off-center from the midline, or a line that coincides with the outer edge of the second engagement surface 122. Additionally, the first groove 132 may only extend along a fraction of the length of the second engagement surface 122. The first groove 132 is dimensioned and configured to slidably receive and slidably engage with a ridge of substantially similar dimensions to the first ridge 130 located on the first elongated portion 110.
In the illustrated embodiment, a second magnet 142 is embedded within the second elongated portion 112. The second magnet 142 is located proximal to the second engagement surface 122 and has a circular cross-section. The second magnet 142 may be a cylindrical magnet with a length that extends along the length of the second engagement surface 122. The second magnet 142 may be contained within a borehole 244 that is formed in the second elongated portion 112. The second magnet 142 may be coupled to the second elongated portion 112 by mechanical friction, adhesive, or any other means of fastening. In the illustrated embodiment, the second magnet 142 is diametrically magnetized, meaning that it is magnetized through the width of the magnet. The second magnet 142 is disposed within a borehole 244 such that the side of the second magnet 142 facing towards the second engagement surface 122 has a polarity that is opposite to the side of the first magnet 140 that faces towards the first engagement surface 120. The second magnet 142 is disposed such that it has a polarity orientation that is opposite to the polarity orientation of the first magnet 140. In other embodiments, the first magnet 140 and the second magnet 142 may have the same polarity orientation. The second magnet 142 may be made from any type of magnetized material such as neodymium iron boron, samarium cobalt, alnico, ceramic magnets, ferrite magnets, or the like. Additionally, it is to be understood that in other embodiments the second magnet 142 may be of any shape, including but not limited to, a cuboid, a triangular prism, a sphere, or the like. In other embodiments, the second magnet 142 may be affixed to an outer surface of the second elongated portion 112 rather than being embedded in the second elongated portion 112. Alternatively, the second elongated portion 112 itself may be made of a magnetized material.
In the illustrated embodiment, a first bridge portion 114 is disposed between the first elongated portion 110 and the second elongated portion 112 and serves to connect the two elongated portions together. The first bridge portion 114 has a substantially cuboid shape and is substantially shorter in length than the first elongated portion 110 and the second elongated portion 112. The first bridge portion 114 comprises a first end 115 and a second end 116. The first end 115 is connected to the first engagement surface 120 of the first elongated portion 110, and the second end 116 is connected to the first attachment surface 124 of the second elongated portion 112. The first bridge portion 114 is connected to distal ends of the first elongated portion 110 and the second elongated portion 112. A continuous surface may be formed by the first elongated portion 110, the first bridge portion 114, and the second elongated portion 112. The first bridge portion 114 is disposed between the first elongated portion 110 and the second elongated portion 112 such that a negative space or open-ended channel 118 is created between the first elongated portion 110 and second elongated portion 112. The open-ended channel 118, which has a substantially U-shaped cross-section, is formed by the first elongated portion 110, the first bridge portion 114, and the second elongated portion 112. The open-ended channel 118 is dimensioned such that a second elongated portion 112 of another interlocking member 100 can fit within it.
In the illustrated embodiment, the interlocking member 100 may comprise a first overhang portion 150 that extends from the first elongated portion 110. The first overhang portion 150 may extend from a side of the first elongated portion 110 that is distal to and opposite from the first engagement surface 120. The first overhang portion 150 serves to facilitate connection of a belt or strap 256 to the interlocking member 100. In the illustrated embodiment, the first overhang portion 150 comprises two side panels 154 and an overhang panel 156. Each side panel 154 extends from opposing outer edges of the interlocking member 100. The overhang panel 156 extends from an edge of the first elongated portion 110 that is proximal to the exterior surface 126. A negative space is created between the side panels 154 and the overhang panel 156 such that a strap 256 can be received. In the illustrated embodiment, there are two first channels 152 that extend through both of the side panels 154. In other embodiments there may not be any first channels 152 or there may be one or more first channels 152. Each first channel 152 extends substantially parallel to the first ridge 130 of the first engagement surface 120 and to the first groove 132 of the second engagement surface 122. Each first channel 152 is dimensioned to receive a first rod 254 that a belt or strap 256 may be attached to.
In the illustrated embodiment, the interlocking member 100 is manufactured out of a single piece of material. The first elongated portion 110, second elongated portion 112, first bridge portion 114, and first overhang portion 150 may be cast or machined as a single piece according to well-known techniques. Boreholes 244 may be machined or cast into the first elongated portion 110 and the second elongated portion 112 to allow magnets to be inserted. In other embodiments, the first elongated portion 110, the second elongated portion 112, the first bridge portion 114, and the first overhang portion 150 may all be separately manufactured components that are affixed together via welding, adhesive, mechanical fasteners, or any other fastening means. Additionally, there are two magnets in the illustrated embodiment: a first magnet 140 in the first elongated portion 110 and a second magnet 142 in the second elongated portion 112. In other embodiments, there may be no magnets, only one magnet, or any other number of magnets. Additionally, if one or more magnets are included, they may be coupled to any of the first elongated portion 110, the second elongated portion 112, or the first bridge portion 114. The location of the magnets may be changed in other embodiments. For instance, an embodiment of the invention may include only one magnet that is embedded in the second elongated portion 112.
A fastening apparatus 200 may be comprised of a pair of interlocking members 100. When one interlocking member 100 is rotated by 180 degrees relative to the other interlocking member 100, the two interlocking members 100 may be slidably and removably engaged with one another to form a secure mechanical connection. The first ridge 130 of one interlocking member 100 may slidably engage with the corresponding first groove 132 of the other interlocking member 100. The first groove 132 of one interlocking member 100 may slidably engage with the first ridge 130 of the other interlocking member 100.

A negative space is created between the side panels 154 and the overhang panel 156 such that a strap 256 can be received. In the illustrated embodiment, there are two second channels 296 that extend through both of the side panels 154. In other embodiments there may no second channels 296 or only one second channel 296. Each second channel 296 extends substantially parallel to the second ridge 280 of the third engagement surface 270 and to the second groove 282 of the fourth engagement surface 272. Each second channel 296 is dimensioned to receive a second rod 298 that a belt or strap 256 may be attached to.
In the illustrated embodiment, the second interlocking member 204 is manufactured out of a single piece of material. The third elongated portion 260, fourth elongated portion 262, second bridge portion 264, and second overhang portion 294 may be cast or machined as a single piece according to well-known techniques. Boreholes 244 may be machined or cast into the third elongated portion 260, the second elongated portion 112, or the second bridge portion 264 to allow magnets to be inserted. In other embodiments, the third elongated portion 260, the fourth elongated portion 262, the second bridge portion 264, and the second overhang portion 294 may all be separately manufactured components that are affixed together via welding, adhesive, mechanical fasteners, or any other fastening means. Additionally, in the illustrated embodiment there are two magnets coupled to the second interlocking member 204: a third magnet 240 in the third elongated portion 260 and a fourth magnet 242 in the fourth elongated portion 262. In other embodiments, there may be no magnets, only one magnet, or any other number of magnets. Additionally, if one or more magnets are included, they may be coupled to any of the third elongated portion 260, the fourth elongated portion 262, or the second bridge portion 264. The location of the magnets may be changed in other embodiments. For instance, an embodiment of the invention may include only one magnet that is embedded in the fourth elongated portion 262.
The magnets serve to facilitate engagement of the two interlocking members. The polarity orientation of the first magnet 140 is disposed to attract the fourth magnet 242 and the polarity orientation of the second magnet 142 is disposed to attract the third magnet 240. Upon the first magnet 140 coming within proximity to the fourth magnet 242, the first magnet 140 and the fourth magnet 242 exert a magnetic force on one another that pulls them together. Similarly, upon the second magnet 142 coming within proximity to the third magnet 240, the second magnet 142 and the third magnet 240 exert a magnetic force on one another that pulls them together. The magnetic attraction between each pair of magnets causes the first interlocking member 202 and the second interlocking member 204 to be pulled together along the engagement axis 235, resulting in the two interlocking members being engaged together. Thus, the magnetic attraction between interlocking members makes it easier for the user to align the first interlocking member 202 with the second interlocking member 204 and slidably engage them together. In some embodiments, powerful magnets, such as neodymium iron boron magnets may be used. In those embodiments, the magnetic attraction between the two interlocking members will cause the interlocking members to interlock along the engagement axis 235 with minimal user intervention: merely placing the first interlocking member 202 close to the second interlocking member 204 will cause them to be pulled together into an interlocked state.
The magnets additionally serve to hold the two interlocking members together once the first interlocking member 202 and the second interlocking member 204 are in an interlocked state. The magnetic attraction between the first magnet 140 and the fourth magnet 242 and the magnetic attraction between the second magnet 142 and the third magnet 240 provide resistance to relative lateral movements of the first interlocking member 202 and the second interlocking member 204 in directions parallel to the A-A′ axis. In other words, the magnetic attraction provides resistance to the first interlocking member 202 and the second interlocking member 204 being pulled apart along an axis parallel to the A-A′ axis.
Once in an interlocked position, the first interlocking member 202 may be disengaged from the second interlocking member 204 by pulling the first interlocking member 202 and the second interlocking member 204 in opposite directions along the A-A′ axis. Once a sufficient force is exerted to overcome the magnetic attraction, the first interlocking member 202 and the second interlocking member 204 may separate from one another.
The first rod 254 and the second rod 298 may be any elongated structure that is suitable for securing a strap 256. For instance, the first rod 254 and the second rod 298 each may be a cylindrical rod that is permanently affixed to the interlocking member. In another embodiment, the first rod 254 and the second rod 298 each may be a spring rod that can be detached from the interlocking member. The first rod 254 and the second rod 298 each may be made from any material, such as plastic, metal, ceramic, rubber, polymer, glass, steel, steel alloy, iron, aluminum, titanium, gold, silver, or the like. In other embodiments, a strap 256 may be attached directly to the first elongated portion 110 via any other fastening method including, but not limited to, stitching, adhesive, welding, or the like. Alternatively, the first rod 254 and the second rod 298 may be integrally connected to the first interlocking member 202 and second interlocking member 204, respectively.
In different embodiments, the fastening apparatus 200 and each of the interlocking member 100, the first interlocking member 202, and the second interlocking member 204 may be composed of any material, such as, aluminum, plastic, rubber, polymer, steel, titanium, metal alloy, metal, ceramic, glass, wood, or the like. In any embodiment of the invention, the fastening apparatus 200 or interlocking member 100 may be dimensioned for use in various applications. For instance, the fastening apparatus 200 of an embodiment of the invention may be used as a fastening device for waist belts, wrist watches, jewelry chains, jewelry ropes, shoes, bags, personal floatation devices, or any other object. The fastening apparatus 200 or interlocking member 100 may be scaled up or scaled down to any size according to any intended use.
