(12) The invention is directed to a necklace adapter for connecting a portable electronic device, such as a smart watch (an example being, but not limited to, an Apple Watch), to a lanyard, cord, or necklace of a user. The invention therefore allows a user to wear a watch or a smart watch as a pendant, and thus be able to wear a conventional watch, bracelets, or other items on their wrist. Additionally, it provides a convent means of individuals with disabilities that either do not have the use of both arms or have lost one to utilize all the convivences of an Apple Watch.

(13) Referring to FIGS. 1 through 5, and initially to FIGS. 1 and 2, there is disclosed a necklace adapter 100 for use in releasably retaining a smart watch or other device about a neck of a user. The necklace adapter 100 generally includes an adapter base 110 and a retainer assembly 112 extending from an upper surface 114 of the adapter base 110. The adapter base 110 is configured to attach to a watch such as, but not limited to, a smart watch, while the retainer assembly 112 is configured to releasably retain a neck cord or necklace of a user.

(14) The retainer assembly 112 includes a lower unit 116, extending from the upper surface 114 of the adapter base 110, and an upper unit 118 movably mounted to the lower unit 116. The upper unit 118 and the lower unit 116 together form a retention clasp 120 for releasable receipt of a neck cord or necklace. The lower unit 116 generally includes a hollow stem 122 having a first or downwardly facing top clasp member 124 extending from an outer surface 126 of the hollow stem 122 and the upper unit 118 generally includes a solid shaft 126 movable within the hollow stem 122 and having a second or upwardly facing bottom clasp member 128. When the solid shaft 126 of the upper unit 118 is moved downwardly within the hollow stem 122 of lower unit 116, the top clasp member 124 and the bottom clasp member 128 together form the retention clasp 120. It is to be understood that the clasp members described herein may take form in a hook shape or a hook. Further, the herein described clasp may take form as a ring shape or ring. For example, the first position causes or forces the clasp members to form a circular clasp.

(15) The adapter base 110, the lower unit 116 and the upper unit 118 may be formed from a variety of materials, such as, for example metallic materials, polymeric materials, etc. When formed from a metallic material, the above-referenced components may be coated or highly polished to compliment the necklace or other jewelry of a user or when formed from a polymeric material may be shaped and/or colored to compliment the smart device being used therewith. The lower unit 116 and/or the upper unit 118 may optionally be decorated with colors, textures, stones or gems, or any suitable decorative addition or combination thereof. Alternatively or additionally, various logos, markings or indicia may be provided on the disclosed components.

(16) In the present exemplary embodiment, the retainer assembly 112 is movably mounted to the adapter base 110 and has a wide range of movement relative to adapter base 110. Specifically, the lower unit 116 is movably connected to the top surface 114 of the adapter base 110 by a ball joint connection 130 which allows the retainer assembly 112 to swivel and pivot relative to the adapter base 110 in the directions of arrows C and D. The ball joint connection 130 also allows the retainer assembly 112 to rotate about a long axis L-L (FIG. 1) of the retainer assembly 112 in the direction of arrow E and relative to the adapter base 110. The retainer assembly 112 may also pivot in an opposite direction of arrow E. This range of movement allows the user to easily position the attached smart watch for convenient use.

(17) As best shown in FIG. 3, the hall joint connection 130 includes a hollow, spherical depression 132 formed in the top surface 114 of the adapter base 110 and a smooth ball 134 provided on a first end 136 of the hollow stem 122. The smooth ball 134 is movably retained within the spherical depression 132 by a press or snap in fit connection to prevent the retainer assembly 112 from separating from the adapter base 110. This connection may be tight and friction fit such that any adjustment of the retainer assembly 112 relative to the adapter base 110 is retained until further moved. The smooth ball 134 may be attached to the hollow stem 122 using known methods or may be intragrally formed with the hollow stem 122. In order to move the retainer assembly 112 relative to the adapter base 110, as well as move the upper unit 118 within the lower unit 116, the solid shaft 126 of the upper unit 118 has a control member or sphere 138 provided on a first end 140 of the solid shaft 126. The control member may take any appropriate shape for being displaced manually or by a user's finger. For example, the control member may be displaced vertically or in some embodiments laterally to cause the clasp members to separate from one another (i.e. causing a gap or separation to form between the tips of the clasp members to receive a necklace). For example, the gap may be large enough to receive a necklace band thickness to receive the necklace band. For example, the gap or separation may be large enough for a thickness of a necklace to pass through the control member may be a sphere or may be a straight or curved bar (a curved shape), and may be configured to displace or rotate one or both of the clasp members (e.g. top clasp member or bottom clasp member). In some embodiments, the necklace adapter is provided with a necklace in a kit.

(18) As noted above, the adapter base 110 is provided for releasable attachment to a smart watch or other device. The adapter base 110 includes a mounting portion or generally rectangular upper platform 142, including the top surface 114, and a connector portion or semi-cylindrical lower platform 144 for insertion into a corresponding channel in a smart watch as described in more detail hereinbelow. The upper platform 142 is affixed to or extends from a relatively flat top surface 146 of the lower platform 144. The lower platform 144 can have tapered first and second ends 148 and 150 to facilitate insertion of the adapter base 110 into the corresponding channel of the smart watch. A longitudinal slot 152 (FIG. 2) is provided in an outer surface 154 of the lower platform 144 of the present embodiment, generally located directly below the spherical depression 132 in the upper platform 142, and functions as a part of a locking device for retaining the necklace adapter 100 in a smart watch. As shown in FIG. 1, the first and second ends 156 and 158, respectively, of the upper platform 142 are longitudinally inward of the first and second ends 148 and 150 of the lower platform 144 such that the upper platform 142 is shorter than the lower platform 144 for functional and aesthetic purposes.

(19) With reference to FIGS. 3 through 5, the solid shaft 126 slides relative to the hollow stem 122 to move the bottom clasp member 128 relative to the top clasp member 124 to open and close the retention clasp 120 about a cord or necklace. In order to bias (e.g. spring bias) the retention clasp 120 to a closed position (e.g. first position), with the top and bottom clasp members 124 and 128, respectively, touching each other (FIG. 4), the retainer assembly 112 includes a spring 160. The spring 160 of the present embodiment is a coil compression spring that is disposed within a hollow bore 162 formed through a second end 164 of the hollow stem 122 and is engaged by a second end 166 of the solid shaft 126. Specifically, a first end 168 of the spring 160 abuts the second end 166 of the solid shaft 126 while a second end 170 of the spring 160 abuts a bottom or base 172 (FIGS. 4 and 5) in the hollow bore 162 of the hollow stem 122. As such, in an assembled state, the solid shaft 126 is disposed within the hollow stem 122 such that the bottom clasp member 128 lies beneath the top clasp member 124, and the tips of the clasp members are adjacently disposed or in contact. In the assembled state, the top clasp member 124 and the bottom clasp member 128 are forcedly biased toward one another via the spring 160 exerting a force on the solid shaft 126 and the hollow stem 122. For example, the bias may be configured to force or separate the solid shaft 124 away (upward in FIG. 3) from the hollow stem 122. The spring may be disposed within the upper unit to bias the control member to the closed clasp position, the spring configured to follow Hooke's law, F=kX where k is a spring constant, F is force, and X is displacement of an end of the spring.

(20) As best shown in FIGS. 4 and 5, the top and bottom clasp members 124 and 128 have arcuate or semi-circular shaped body portions 174 and 176 and terminate in respective free ends or tips 178 and 180. A connecting end 182 of the body portion 174 top clasp member 124 is affixed to, or integrally formed on, an outer surface 184 of the hollow stem 122 at the second end 164.

(21) In order to move the bottom clasp member 128 of the upper unit 118 (which is outside the hollow stem 122) relative to the top clasp member 124 of the lower unit 116 in response to movement of the solid shaft 126 (which is inside the hollow stem 122), the hollow stem 122 includes a longitudinal slot 186 which extends from the outer surface 184 of the hollow stem 122 to the bore 162 of the hollow stem 122. The longitudinal slot 186 may take any appropriate shape, such as an L shape, in embodiments where the bottom clasp member 126 and the solid shaft 122 are integral, such that the solid shaft 126 may be inserted downward into the hollow stem 122 and rotated to bring the bottom clasp member 126 and the top clasp member 124 into alignment as shown in FIG. 2. For example, the longitudinal slot 186 may have a first vertical portion disposed toward a top end of the hollow stem 122, a horizontal portion extending laterally relative to the vertical portion, and a second vertical portion where the clasp members become aligned as shown in FIG. 2. A short shaft or bar 188 is provided on the upper unit 118 and connects a connecting end 190 of the bottom clasp member 128 to an outer surface 192 of the solid shaft 126. The short bar 188 rides in and passes through the longitudinal slot 186 in the hollow stem 122. As such, the lower unit may be attached to a top of the adapter base, from which the bottom clasp member extends upwardly to a lower terminal tip. The upper unit may be attached to the lower unit, from which a top clasp member extends downwardly to an upper terminal tip. Further, the control member may be displaceably secured to the upper unit, the control member mechanically attached to selectively displace the bottom clasp member between the closed clasp position and the open clasp position. The upper unit and the lower unit may be adjacent such that the bottom clasp member and the top clasp member form a retention clasp in the closed clasp position.

(22) In operation, pressing down in the direction of arrow A (FIGS. 4 and 5) moves the solid shaft 126 downward with the hollow bore 162 of the hollow shaft 122 and against the bias of spring 160. This moves the top and bottom clasp members 124 and 128, respectively, from the first closed position (FIG. 4) wherein the end tips 178 and 180 of the top and bottom clasp members 124 and 128 are in close or full contact to a second open position (e.g. open position) (FIG. 5) wherein the end tips 178 and 180 are spaced apart. In the second, open position, the retention clasp 120 can receive a cord or necklace. In the first, closed position, the retention clasp 120 can retain the cord or necklace. As such, the control member and the bottom clasp member are attached such that displacing the control member causes the bottom member to rotate and increase the separation between the tips of the clasp members.

(23) In this particular embodiment, the orientation of the lower platform 144 of the adapter base 110 is offset from the upper platform 142 for ease in insertion of the lower platform 144 into a channel in a smart watch. Specifically, a center line LP-LP of the lower platform 144 is at an angle n relative to a center line UP-UP of the upper platform 142. It should be noted that, while in FIGS. 4 and 5 the center line UP-UP of the upper platform 142 is shown as coinciding with the long axis L-L of the retainer assembly 112, since the retainer assembly 112 is movably mounted to the adapter base 110 and specifically to the upper platform 142, through the ball joint connection 130, the center line UP-UP of the upper platform 142 will move relative to the long axis L-L of the retainer assembly 112 as the retainer assembly 112 is moved relative to the adapter base 110.

(24) Referring now to FIGS. 6 through 8, and as noted above, the disclosed necklace adapter 110 is provided for use with a device such as, for example, smart watch 200. Smart watch 200 generally includes a body portion 210 having a display screen 212 for displaying information 214. Switches 216 and 218 are provided for operating the device through its various functions. Generally, the smart watches 200 include an arcuate, longitudinal channel 220 formed in an upper edge 222 of the body portion 210. The channel 220 is normally used for receipt of a lanyard or other wrist connection.

(25) With specific reference to FIGS. 6 and 7, in use, the necklace adapter 100 is initially attached to the smart watch 200 by sliding the lower platform 144 into the longitudinal channel 220 in the smart watch 200. This secures the necklace adapter 100 to the smart watch 200 and readies it for use. As shown in FIG. 7, the tapered first and second ends 148 and 150 of the lower platform 144 conform to arcuate, upper edges 226 and 228 of the body portion 210 of the smart watch 200 to create a non-snagging surface.

(26) Referring now to FIG. 8, it should be noted that if the smart watch 200 has a locking button 224, the locking button 224 can be activated to fixedly engage the smart watch 200 to the necklace adapter 100. This is accomplished by providing a bar or other protrusion (not shown) on the smart watch 200 which, when activated, extends into the longitudinal channel 220 of the smart watch 200. The protrusion will extend into the longitudinal slot 152 (FIG. 2) on the lower platform 144 of the necklace adapter 100 and fixedly and releasably secure the lower platform 144 within the longitudinal channel 220 of the smart watch. Reactivation of the locking button 224 will withdraw the protrusion from the longitudinal slot 152 to unlock the necklace adapter 100 and free it for removal from the smart watch 200.

(27) To attach the necklace adapter 100, before or after attachment to the smart watch 200, to a cord or necklace, such as, for example, necklace 250, the sphere 183 is pressed down to move retention clasp 120 to the open position as specifically described in detail hereinabove. The bottom clasp member 128 is moved down and away from the top clasp member 124, against the bias of the spring 160 (FIG. 5) for receipt of the necklace 250. Once the necklace 250 has been positioned between the top and bottom clasp members 128 and 124, respectively, pressure is release from the sphere 138 allowing the spring 160 to bias the solid shaft 126 up relative to the hollow stem 122 and move the retention clasp 120 back to the closed condition about the necklace 250.

(28) Thus, in this manner, the disclosed necklace adapter 100 provides a simple and useful system and method of attaching the smart watch 200 to the necklace 250 worn around the neck of a user. The ball joint connection 130 of the necklace adapter 100 allows the user to pivot the smart watch 200 relative to the necklace 250 and/or the chest of the user to facilitate viewing and use of the smart watch 200. This allows and frees up the user to have other smart watches on the wrist, as well as keeping the smart watch 200 available for immediate use.

(29) Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
