Extendable and retractable coupling system

Abstract

An extendable and retractable coupling system is configured with a retractable coupler that is tethered to a coupler body to retain valuable item to a person or other item. An extendable coupling system has a dual coupler having a fixed coupler that is stationary, or configured on the coupler body and a retractable coupler that is coupled to the coupler body by a tether. The retractable coupler may be coupled to a valuable item, such as a mobile phone and the fixed coupler may be coupled to a person clothing, such as to a belt loop, for example. The user may then extend the tether to use their mobile phone and place the phone back into a pocket when not in use. The tether may prevent the valuable item, such as the mobile phone, from dropping to the ground and being damaged.

The embodiments described are only for purposes of illustrating the present invention and should not be interpreted as limiting the scope of the invention. Other embodiments of the invention, and certain modifications, combinations and improvements of the described embodiments, will occur to those skilled in the art and all such alternate embodiments, combinations, modifications, improvements are within the scope of the present invention.

(13) Referring now to FIGS. 1 and 2, an exemplary dual coupler 12 of an extendable coupling system 10 has a stationary body coupler 50 and a retractable coupler 60 having a retractable coupler body 61, wherein the retractable coupler is extendable from the coupler body 20 by a tether 42. The coupler body has a length from the first end 22 to the second end 24. The body coupler is configured on the first end 22 of the coupler body and comprises a body coupler latch 56 that has an extended end 58 that rotates into a body coupler aperture 55 of the coupler body 20. The body coupler latch rotates about a pivot on a pivot end 57. The retractable coupler 60 is configured on the second end 24 of the coupler body and comprises a retractable coupler latch 66 that has an extended end 68 that rotates into a retractable coupler aperture 65. The retractable coupler latch rotates about a pivot end 67. The retractable coupler extends away from the coupler body 20 and has an extended end 63 and a tethered end 62. The retractable coupler is drawn back into a receptor recess 36 in the coupler body 20 and when in a stowed configuration, as shown in FIGS. 1 and 2, the outer perimeter 21 of the coupler body is smooth and continuous, as defined herein. This smooth and continuous outer perimeter prevents the dual coupler from getting snagged on clothing during use.

(14) The retractable coupler is extended from and retracted back by a spring loaded tether device 40 having a spring 44, that retracts the tether 42 around a spool 46. The spring may be a torsional spring. The tether has a retained end 48, which may be retained to the spool and a coupler end 47 which is coupled to the tether end 62 of the retractable coupler 60.

(15) As shown in FIG. 3, the coupler body 20 of the dual coupler 12 has a planar top surface 25 and bottom surface 27. The edges of the coupler body may be smooth having no sharp angles and may have curved surfaces. The thickness of the coupler body 26 may be kept relatively low for ease of use when retained in the pocket of a garment, for example. The coupler body is substantially planar wherein the top and bottom surfaces are substantially parallel and offset by a coupler body thickness.

(16) As shown in FIG. 4, exemplary dual coupler 12 of an extendable coupling system 10 has the retractable coupler 60 extended from the dual coupler body 20 and both the body coupler latch 56 and retractable coupler latch 66 are in an open configuration. The tether 42 has a tether length 43 as described herein. The receptor recess 36 is tapered from a larger opening at the outer perimeter 21 toward the spring loaded tether device 40. Likewise, the retractable coupler 60 is tapered toward the tether end 62 and has a centering feature 69 that has a geometric shape to fit within a receiver in the receptor recess, proximal to the spring loaded tether device 40.

(17) Referring now to FIGS. 5 and 6, an exemplary mobile device attachment 90 has corner extensions 94, 94′, 94″, 94″ for extending over the corners of a mobile device. The corner extensions are formed by corner apertures 92, 92′, 92″, 92′″ through the mobile attachment device. The mobile attachment device has an attachment tab 96 extending therefrom with an attachment loop 98 on the extended end of the attachment tab. The attachment tab, may be detachably attachable to the mobile device attachment or the two components may be a monolithic part that may be formed by a single piece of material, such as a molded part.

(18) As shown in FIG. 7, an exemplary mobile attachment 90 is coupled to a mobile device 15, such as a mobile phone, with the corner extension 94, 94′, 94″, 94′″ extending over the corners of the mobile device. The attachment tab 96 extends from the mobile device to receive the retractable coupler.

(19) As shown in FIG. 8, an exemplary mobile device attachment 90 has is coupled to a mobile device 15 by being retained in the mobile device cover 18 with the attachment tab 96 extended out through an aperture 17 in the cover.

(20) As shown in FIG. 9, an extendable coupling system 10 comprising a mobile device attachment 90 attached to a mobile device 15, such as a mobile phone and the retractable coupler 60 is attached to the attachment loop 98 at the end of the attachment tab 96. The retractable coupler 60 is coupled to the coupler body 20 by the tether 42 and the dual coupler 12 is attached to a body coupler loop 16, such as a belt loop. The spring loaded tether 40 may provide enough support to avoid a catastrophic fall to the ground of the mobile device whereby the length of the tether will limit how far the mobile device can extend from the coupler body. The spring loaded tether device 40 may produce enough force on the tether 42 to retract the mobile device 15 back to the dual coupler 12.

(21) It will be apparent to those skilled in the art that various modifications, combinations and variations can be made in the present invention without departing from the scope of the invention. Specific embodiments, features and elements described herein may be modified, and/or combined in any suitable manner. Thus, it is intended that the present invention cover the modifications, combinations and variations of this invention provided they come within the scope of the appended claims and their equivalents.
