Various embodiments include bullet-resistant multilayered curtain that can be quickly deployed to secure an entranceway from attackers and deter them from entering. A bullet-resistant multilayered curtain may be contained above an entranceway in a casing and supported by a quick release pin when in the stored configuration. The bullet-resistant curtain includes multiple horizontal bars that are distributed along the length of the bullet-resistant curtain. Firmly fixed on the perimeter of the entranceway are horizontal bar retainer clamps for locking the horizontal bars into place when the bullet-resistant curtain is in its deployed state. A vibration sensor control switch may be fixed on the perimeter of the entranceway and configured to activate vibration sensors fixed on the bullet-resistant curtain to detect vibrations and send notifications to remote authorities.

A barrier includes a frame and a gate engaged within the frame, the barrier has a first state and a second state, a length of the frame in the second state being smaller than that in the first state, and a length of the gate in the second state being smaller than that in the first state.

Described is a pallet including a base having a length extending between a first end and a second end opposite the first end and a width transverse to the length; and a cage removably coupled to the base.

The invention relates to a double articulated device and system comprising at least one active element provided with an edge (M), with two points (M1) and (M2), where (M1) is different from (M2), a rotating element connected to the edge (M) and a rotating fixture positioned in the point (M1) of the edge (M) and connected to the rotating element, in which, during actuation, the active element simultaneously describes a rotational movement with an angle β around the rotating element, and a partial pivoting movement in the vertical plane around the rotating fixture, so that the point (M2) of the edge (M) describes an angle a between a value α.sub.max corresponding to the “open” position ES0 and a value α.sub.min which corresponds to an ES1 “closed” position of the device.

A collapsible gate may provide a temporary barrier to prevent movement between rooms, or to prevent access to a staircase, in a home or commercial building. The collapsible gate may be secured to framing material within a wall and adapted for storage within a wall cavity, such as a pocket door frame, when not in use. The collapsible gate may be vertically retractable and adapted to fit between two framing studs to stow within a wall cavity and out of sight. The collapsible gate may include a counterbalance to maintain the gate within the wall cavity when the gate is in the fully open position, and to assist in opening the gate when the gate is lifted from a closed position.

Described is a pallet including a base having a length extending between a first end and a second end opposite the first end and a width transverse to the length; and a cage removably coupled to the base.

A folding hanger includes a hook extending from an upper end of a hinge pin for suspending the pin. First and second hanger arms each have proximal and distal ends and define a support surface therebetween. Each proximal end has a stop. A knuckle having a hole extends from each proximal end. The pin passes through the holes along an axis, coupling the arms and hook whereby the arms are movable between extended and folded configurations. The stops abut when the arms are extended, and are separated when folded. The hanger has a center of gravity when the arms are extended and suspended by the hook such that the axis is angled relative to vertical in a first direction and the stops bias abutting. The arms each have a center of gravity such that angular movement of the axis past an unstable equilibrium causes the arms to move toward folded.

An illustrated view of an exemplary security shield device for securing a window is presented. The security shield device is easy and efficient to install and use. Also, the security shield device is useful for allowing a user to still have full site out of the window when the security shield device is retracted. The security shield device is further useful for doors in homes and business alike.
