The invention is novel in structure, convenient to use, easy to carry, and can provide a good man-machine interaction mode.

A clip device includes a membrane body having a flat surface and a tapered end fixed to the membrane body. The tapered end is clipped to a retractable cord. The flat surface of the membrane body is sandwiched between a case of a handheld device and the handheld device and the tapered end has a portion protruding from the case through an opening of the case

A device case with a strap adapted to allow the user to hold an electronic device with the aid of a strap. The device case is adapted to receive an electronic device, such as a cellular telephone, with a case with rimmed sides that capture the electronic device. The strap may unclip and move along a fixed path, exposing a clip adapted to be received by a clip receiver, such as on a tripod. An attachable device strap adapted to be adhesively fastened to the back side of an electronic device, such as a cellular telephone, or to the back side of a case holding a cellular telephone. The strap may unclip and move along a fixed path, exposing a clip adapted to be received by a clip receiver, such as on a tripod. Accessories such as stands, holders, and lights may be couple to the exposed clip, adding other functionalities to the case system.

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.

An expandable device includes a base having a top side and a bottom side, an expanding mechanism operably coupled to the base, and a button. The bottom side of the base is adapted to engage a portion of a portable electronic device. The button has a top side and a bottom side and is operably coupled to the expanding mechanism. The expanding mechanism is selectively movable between a first configuration whereby the button is disposed in a first, collapsed configuration and a second configuration whereby the button is disposed in a second, expanded configuration. Upon urging the button to the first configuration, the expandable device retains the button in the first configuration, and upon further urging the button towards the base, the button is released from the first configuration and moves to the second configuration

An expandable device for attachment to a foldable electronic device having first and second surfaces includes a button and a pivotable frame member. The button has a top side, a bottom side, and a coupling portion and is movable between an expanded configuration and a collapsed configuration. The pivotable frame member is operably coupled to the button and includes a device coupling portion that engages a portion of the foldable electronic device. The pivotable frame member is pivotable between a first configuration whereby the button is positioned along at least one of the first surface or the second surface of the foldable electronic device and a second configuration whereby the button is positioned away from the foldable electronic device.

An electronic device case including a case body to encase a handheld electronic device, the case body including at least one planar surface, and one or more wings to fold into the planar surface in a first position and to extend past an edge of the at least one planar surface in a second position. The one or more wings provide handles by which a user of the handheld electronic device can support a weight of the handheld electronic device

A tether system and apparatus is provided for securing a handheld device to a user. The tether apparatus includes a harness having an elastomeric body configured to engage the plurality of corners of the handheld device thereby releasably securing the elastomeric body to the handheld device, a fastener configured for releasably engaging an article worn or borne by a user, and an elongated tether interconnecting the fastener and the harness. A first end of the tether is connected to the elastomeric body, and a second end of the tether is connected to the fastener. The elastomeric body and the elongated tether may be monolithically formed. The tether apparatus allows a user to easily retrieve the handheld device if dropped.

Injury to the digits, hand and wrist are associated with the frequent usage of portable hand-held electronic devices (“PEDs”), including but not limited to smartphones. This is true as well for injury to the neck and shoulder areas. The potential for injury to the digits, hand and wrist in particular is anticipated to be exacerbated by the larger smartphones, and especially the tablet-like smartphones. The ergonomic accessory of the invention has several embodiments whose design is intended to ameliorate if not prevent such injuries. Certain embodiments are partially or fully case-like in form so that they envelope to a greater or lesser degree, such hand-held electronic devices. Another embodiment attaches to a PED through an element of the PED such as the charging socket. The accessory also removably attaches the hand of the user or provides a secure holding surface for the user.

The invention is directed to a compacting grip apparatus for a hand-held touch screen electronic device. The apparatus includes an extension portion comprising an extendable ribbon-shaped structure, the extension portion having a first end and an opposing second end. In some embodiments, the extension expands to an open position and contracts to a closed position. The apparatus includes a hard base that includes a flat outside face and an inside portion fixedly connected to the first end of the extension portion. The apparatus includes a hard top that includes an inside portion fixedly connected to the second end of the extension portion and a flat or plate-like outside face facing away from the outside face of the base.
