A lanyard attachment device and lanyard system using the same is disclosed herein. The lanyard attachment device includes a first leg portion, the first leg portion configured to be attached to a first end of a lanyard; a second leg portion, the second leg portion configured to be attached to a second end of the lanyard; and a base portion connected to the first leg portion and the second leg portion. The first leg portion, the second leg portion, and the base portion collectively defining a closed-ended slot for receiving a stem portion of a device holder. The lanyard system includes a lanyard and a lanyard attachment device configured to be attached to the lanyard.

The swivel lock quick release device is adapted to selectively attach a user to a sports equipment. The sports equipment may be watersports equipment, such as a surfboard, a kite surfing apparatus, a stand-up paddle board, sailing equipment, a wake board, etc., or land sports equipment, such as fishing, camping, climbing, animal collars or leashes, tactical rifle apparatus, and hunting equipment. The swivel lock quick release device having a pull release and a protrusion, the pull release and the protrusion being adapted to be selectively engaged in a locked position is provided. A slide handle, a portion of the pull release, is adapted to be selectively moved in a coaxial direction by the user to disengage the pull release and the protrusion. The pull release is also adapted to rotate around, or swivel, the protrusion.

An expandable device for use with a portable electronic device includes a body, a button, a platform, and a locking device. The body has a first end, a second end, and a longitudinal axis, and is movable between an expanded configuration and a collapsed configuration. The button is coupled to the first end of the body, and the platform includes an outer surface and a collar extending away from the outer surface. The collar defines a cavity. The locking device is carried by the second end of the body, and at least a portion of the locking device is adapted to be removably disposed in the cavity of the platform for releasably coupling the body to the platform. The locking device is rotatable relative to the platform between an unlocked configuration, in which the body is removable from the platform, and a locked configuration, in which the body is secured to the platform.

Disclosed is a belt holder for a tape measure, including: a holder body configured to be mounted on the belt; a rotary mount rotatably coupled to a front surface of the holder body; a locking bracket provided at the holder body or the rotary mount; and a restoring spring elastically supporting the locking bracket in one direction.

A tool tethering device that includes a lockable shaft having a cylindrical shaped body with a protruding member located proximal a first end and extending perpendicular from the cylindrical shaped body, a rigid sleeve housing having a cylindrical shaped cavity located within and extending from an open end to a closed end of the rigid sleeve housing, a protruding member engaging slot extending from and running parallel the cylindrical shaped cavity, a ball bearing engaging groove located within the cavity, a protruding member locking groove located within the sleeve housing proximal the closed end of the housing and extending perpendicular the cavity, and a displaceable platform located within the cylindrical shaped cavity between the protruding member locking groove and the closed end of the rigid sleeve housing, the displaceable platform supported by a spring located between the platform and the closed end of the rigid sleeve housing.

A load-carrying fastener with rapid attachment and detachment and safety lock mechanisms is applicable to an attachable holder for a MOLLE accessory and includes a fastener base; a pivotable locking plate pivotally connectable with the fastener base; and a lock-release key flippable to keep the fastener base and pivotable locking plate in an interlocked or released state. Two lateral sides of the fastener base are formed with elastic arms extending outward to form locking arms with locking hooks. The pivotable locking plate is formed with two locking holes allowing the locking arms to be inserted therein and the locking hooks to hook the edges thereof when being closed on the fastener base, so as to enter into a locked state, and be brought with the fastener base into an unlocked state by disengaging the locking hooks from the hole edges when the elastic arms are pressed.

A tool attachment system is provided. The tool attachment system includes a tool attachment device and a receiver that cooperate to lock or secure, for example, a bag or pouch. When the tool attachment device is coupled to the receiver, a locking mechanism locks the tool attachment device to the receiver in a locked position. To remove the tool attachment device, a user applies a force to a button to cause the tool attachment device to disengage from the receiver.

The swivel lock quick release device is adapted to selectively attach a user to a sports equipment. The sports equipment may be watersports equipment, such as a surfboard, a kite surfing apparatus, a stand-up paddle board, sailing equipment, a wake board, etc., or land sports equipment, such as fishing, camping, climbing, animal collars or leashes, tactical rifle apparatus, and hunting equipment. The swivel lock quick release device can have a pull release and a protrusion, the pull release and the protrusion being adapted to be selectively engaged in a locked position is provided. A slide handle, a portion of the pull release, is adapted to be selectively moved in a coaxial direction by the user to disengage the pull release and the protrusion. The pull release can also be adapted to rotate or swivel around the protrusion.

Disclosed is a belt holder for a tape measure, including: a holder body configured to be mounted on the belt; a rotary mount rotatably coupled to a front surface of the holder body; a locking bracket provided at the holder body or the rotary mount; and a restoring spring elastically supporting the locking bracket in one direction.
