A collapsible, self-expanding polyhedron comprises a plurality of side members each connected with an elastic band that is sized to urge each side wall of adjacent side members together to form an expanded configuration. When the polyhedron is compressed on two opposing side members, which causes the other side members to separate into a collapsed configuration, the elastic band expands to a maximum length with maximum tension. Once the compression is released, the at least one elastic band retracts back to a minimum length and urges the side members back into the expanded configuration.

Personal protective devices have a carrying bag, such as a purse, and a separate bullet resistant vest or penetration resistant (to stab wounds) vest comprises at least one neck sling and at least one torso strap. The bullet/penetration resistant vest is dimensioned to removably fit within the carrying bag. The carrying bags are configured to provide a 'ready state' wherein a bullet resistant shield and neck sling are within the carrying bag while at least a connector attached to the end of a deployable torso strap(s) is outside of the carrying bag. The carrying bag has at least one slot designed to allow the torso strap(s) to be pre-fed from the interior of the carrying bag to a position exterior of the carrying bag. In this 'ready state', the majority of the torso strap is maintained within the interior of the carrying bag. The neck sling and torso straps are deployable to secure the vest to a wearer's torso in the deployed position.

A connector for joining two pieces of sheet metal together end-to-end. A second wall and a first wall define a first channel therebetween, into which a ledge extends, and which lockingly receives one piece of sheet metal, by virtue of at least one reverse button lock on a raw free end of the one piece of sheet metal snapingly engaging against the ledge. A third wall terminates in a free edge that is folded onto itself, and together with the first wall, defines a second channel therebetween that lockingly receives the other piece of sheet metal, by virtue of at least one reverse button lock on a raw free end of the other piece of sheet metal snapingly engaging against the folded free edge of the third wall.

A hand-held tool for guiding an integral piece of sheet metal into a pair of sheet metal connectors positioned end-to-end and oriented at an angle relative to each other so as to form a corner. Each sheet metal connector has a pair of spaced-apart walls that define a channel therebetween for receiving the integral piece of sheet metal, and a flange that extends outwardly from one wall thereof. The tool includes a handle and a blade that extends axially from the handle. The blade is shaped for inserting into the channel of each of the pair of sheet metal connectors simultaneously, at the corner, and defining with the other wall of each of the pair of sheet metal connectors a converging pathway for guiding the integral piece of sheet metal into the channel of each of the pair of sheet metal connectors simultaneously, at the corner.

A slip lock connector assembly for joining end-to-end first and second flat-sided ducts made of sheet metal, has a framelike structure defined by a plurality of similar connecting members arranged in coplanar array. Each connecting member is made of pliable sheet metal bent, rolled, and molded to proper form. Each member has a flat main wall with first and second walls at opposite sides defining first and second channels. Both channels are filled with sealant material. The flat end of a side of the first duct in slipped into the first channel and secured by auxilary fastening elements, whereby the sealant in the first channel seals the connector to the flat end of the first duct. The flat end of a side of the second duct is slipped into the second channel and sealed by the sealant therein. In addition the wall of the second channel is formed with a rolled ledge which engages with lock projections on a side of the second duct to secure the second duct to the second channel. The second channel may have a laterally extending flange to stiffen the structure of the connecting member.

A backboard and rim assembly is provided for use with a sponge basketball. A basketball rim is secured to a base member which is pivotably attached to a basketball backboard. The rim is attached in such a manner that it may swing between a downward position parallel to the plane of the backboard and an upright position perpendicular to the plane of the backboard. A base member is pivoted at its lower end to the backboard and is connected at its upper end to the rim. A stop block is positioned between the backboard and rim to limit upward swinging of the rim. A hook extends from each side of the stop block. A rubber band is attached at each end to one of the hooks and is positioned to underly the base member thus biasing the rim upwardly against the stop block. When a downward force is applied to the rim, the rubber band stretches to permit the rim to swing downward toward the parallel position. When the force is removed, the rim will recoil and return to its perpendicular position.
