A case, having a standing leg for an electronic device, includes: a soft protective cover for protecting the electronic device installed therein, covering a back portion of the electronic device; a hard protective frame, constructed to removably mount over the soft protective cover; a standing leg for propping up the electronic device; and a recess formed on a back portion of the hard protective frame wherein the standing leg fits in the recess and the standing leg is pivoted with the soft protective cover and the hard protective frame.

A grip system comprises a protective case and a grip apparatus. The grip apparatus is removably attachable to a back surface of the protective case. The grip apparatus includes a base, two flexible strips or straps, and a cap. The base is configured to be removably inserted into the recess in the back of the protective case. The two flexible strips are each attached to the base. The cap is proximate a top surface of the base when in a stowed position and extendable away from the top surface of the base when the cap is pulled outward to an extended position. Each flexible strip is configured or adapted to slide within a slot or channel in the cap. Each flexible strip slides into the slot when the grip apparatus is transitioned to the stowed position and slides out of the slot when transitioned to the extended position.

A housing supporting apparatus includes: a base-plate body having a base-plate axis; a connection plate body having one end formed with a connection plate axis and pivotally connected to one end of the base-plate body; a first supporting plate having a first axis pivotally connected to the one end of the connection plate body; and a second supporting plate having a second axis pivotally connected to one end of the first supporting plate. The second supporting plate has one end pivotally connected to the base-plate axis.

A stand for a mobile phone, the stand comprising: a plate configured to be removably attached to a back of a mobile phone or phone casing; a support panel having a first end and a second end, the first end configured to pivotably engage a lower edge of the plate about a first axis and the second end configured to rest on a surface on which the stand and the mobile phone are placed when the stand is attached to the mobile phone; an adjustment leg having a pivoting end and an engagement end, the pivoting end configured to pivotably engage an upper edge of the plate about a second axis and the engagement end configured to releasably and selectably engage the support panel at one of a plurality of engagement locations provided along a length of the support panel.

A method includes providing a main frame configured to be attached to a surface associated with a portable electronic device, and providing a flexible strap. The method also includes forming a grip device based on receiving slide elements of the flexible strap through a channel of the main frame, and enabling operations associated with the portable electronic device and support thereof on a flat surface through the attachment of the formed grip device to the portable electronic device.

A portable stand for a wind musical instrument including an instrument peg, a first-stand-section, and a second-stand-section. The instrument peg includes an instrument interface and a stand interface, with the instrument interface configured to removably interface with, and support the wind musical instrument. The instrument peg includes a first-inside face, a first-outside-face, and a first-perimeter extending, with the first-perimeter extending between the first-inside-face and the first-outside-face. The second-stand-section includes a second-inside-face, a second-outside-face, and a second-perimeter extending between the second-inside face and the second-outside-face, with the second inside-face including a second-recess dimensioned and sized to receive the complementary portion of the instrument peg.
