An electronic device with extendable strap and different communication modes depending on the state of the strap comprises a shell, at least one rotating mechanism, a strap, a sensor, and a processor. The shell defines at least one first receiving cavity, the rotating mechanism is received in the first receiving cavity. One end of the strap is wound on the at least one rotating mechanism. The rotating mechanism is able to rotate and store spring force under a driving of the strap. The sensor communicates with the processor to determine the state of the strap according to a rotation direction of the rotating mechanism and thus determine whether the strap is retracted to allow touch screen input by a user, or extended to switch to voice communication with the user.

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.

A wearable device including a flexible elongated member, a retractor, and a cloth is disclosed. The flexible elongated member may comprise a bistable spring and may be wrapped around the appendage of a user by exerting a deformation force upon the flexible elongated member. The retractor may be removably connected to the flexible elongated member via an attachment feature and attachment element, and the cloth may be retractably connected to the retractor via a cable. During use, the cloth may be pulled away from the appendage of the user, whereby a retraction mechanism disposed within a housing of the retractor may provide an opposing retracting force that urges the cloth back toward the appendage of the user. An ornament may be attachable to the retractor.

A retractable holder for a smartphone is formed with a housing, a connection mechanism for connecting and disconnecting the smartphone to the housing, a first lanyard loop comprising lanyard cords that are reeled onto or deployed from cord storage spools located inside the housing, a second lanyard loop comprising lanyard cords that are reeled onto or deployed from cord storage spools located inside the housing and a lanyard control mechanism. The lanyard control mechanism applies a retracting force to each of the cord storage spools, the retracting force operational to reel the lanyard cord extending from the housing in a deployed state to the cord's respective cord storage spool and to enable a user draw out and deploy a fixed length of the lanyard cord from the cord's respective cord storage spool.

One embodiment of the present invention relates to an improved camming stem system including a head member, a plurality of cam lobes, a connection system, and a retraction system. The cam lobes may be selectively rotatable between an extended state and a retracted state with respect to at least one axle of the head member. The connection system may create an elongated, substantially rigid region by intercoupling the head member with a loop. The connection system includes a cord continuously wrapped around the head member and loop. The continuous configuration of the cord around both the head member and the loop creates the necessary minimum tensile strength for operation of the camming system. The cord may be wrapped around a rivet or one or more axles of the head member. Independent regions of the cord may be spliced together to form the continuous configuration.

Disclosed herein is a bag configured such that the length of a bag strap used to hold the bag on a user's body is easily adjustable and an adjusted region is not exposed to the outside, thus enabling a neat appearance to be reliably maintained and allowing the bag to be safely used. The bag includes a sack-shaped main body configured to receive objects and a bag strap normally connected to the main body and used to hold the bag on a user's shoulder, waist or the like. One end of the bag strap is coupled to one end of the main body, a wire of a predetermined length is connected to the other end of the bag strap, and the main body includes an adjusting means that adjusts the length of the wire by winding or unwinding, in the state where an end of the wire is fixed.

A retractable retrieval device comprising a lanyard, a retractable element, a retractable cord and a connecting element. The retractable element comprises a first end coupled to the lanyard and a retractable cord coupled to the connecting element is coupled to the retractable cord. The connecting element of the retractable retrieval device may be coupled to a reach extender.

This invention is embodied in a body mount and retractable lanyard that enables its user to pull and retract a device perpendicularly from the face of a spool connected to a user. In this way, the body mount enable its user to access hands-free portable power, video and data transfer for public safety personnel and others operating in extreme and challenging environmental conditions.

A holder for use with at least one of a badge card and an electronic authentication device may include a first housing section including a first interior surface that at least partially defines a first slot sized to receive the badge card therein. The first housing section may further include a first projection extending from the first interior surface and positioned to contact the badge card when the badge card is received in the first slot. The holder may further include a second housing section coupled to the first housing section including a second interior surface that at least partially defines a second slot sized to receive the electronic authentication device therein. The second housing section may further include a second projection extending from the second interior surface and positioned to contact the electronic authentication device when the electronic authentication device is received in the second slot.

A lanyard device suitable for connecting a tool to a user in use, including a housing at least part of which is adapted to be connected to clothing, belt and/or safety harness. The housing including at least one socket means formed thereon and/or therein, said device also including a flexible lanyard or tether means, at least one end of which is adapted to connect to a tool in use. At least part of the said lanyard means includes a portion to be received and/or engage with said socket means and said socket means shaped and/or orientated such that the flexible lanyard cannot pass freely through said socket means when the user lets go of the tool and/or lanyard.
