Abstract: A wall anchor assembly has a pair of posts extending from a collar. The collar has an opening for passing a part of a bolt. Distal from the collar, the posts are connected by a connector. An anchor member is captive between the posts and between the collar and the connector. The assembly has a penetrating configuration in which the anchor axis is substantially parallel to the assembly axis, and the anchor body portion and posts form a body portion. A tongue protrudes from an inside surface of a post and engages a groove on the anchor member in the penetrating configuration with the longitudinal anchor axis substantially parallel to the assembly axis, and transmits axial rotation from the collar to the anchor member. The bolt engages a hole in the anchor to draw the anchor member against the wall to clamp the anchor assembly to the wall.

Abstract: A plastic hollow wall anchor having folding arms for insertion within a limited diameter aperture in a substrate such as a wall. The arms, adjacent their overlapping attachment areas, are configured to provide a "sharp knife edge" intersection, whereby a spacing between the attached arms, during folding and aperture insertion, is substantially eliminated. The load bearing arms are concomitantly thickened and thereby strengthened within the limited dimension afforded by the aperture. Alternatively, the overall dimensions of the anchor are reduced, while maintaining the load bearing arm dimensions, thereby enabling the use of a smaller diameter for the insertion aperture without decrease in anchor holding strength.

Abstract: A plastic over-center hollow wall anchor having increased strength without increase in thickness of load bearing members and necessitation of a larger insertion aperture. The bending motion stress on the load bearing arms, which causes the weakening or failure mode of the anchor, is substantially retarded by the inclusion of a small reinforcing boss across the bending area.

Abstract: An expansible plastic fastener comprising a generally elongated body portion, a collar member, and locking means comprising a pair of reinforced toggle arms. The body portion has a generally central opening for reception of an elongated retaining element. The reinforcement provides cooperative resilient interaction with the toggle arms to assist movements toward their collapsed and expanded portions while simultaneously contributing to their holding strength. The fastener can also include a Y-shaped reinforcing portion pivotally connected to the locking means of the body portion by flexible connector means. This Y-shaped portion may include means for engaging an elongated retaining element in the form of a threaded member. Also, a fastening kit comprising a fastener of the invention along with a key for expanding the locking means to its optimum expanded position or a fastener of the invention with an elongated retaining element.

Abstract: A multi-function integrally molded plastic fastener for insertion within a hole in a wall for fastening objects to any of solid, thick or thin hollow walls. The fastener comprises a base element and an anchoring element with the base element being positioned within the hole and depending whether the wall is solid, thick or thin hollow wall, the anchoring element is positioned totally within, partially within and totally behind the wall respectively. The anchoring element is comprised of outstretched anchoring arms which are collapsible for insertion within the hole and which arms have interfitting sections of a sinusoidal wave configuration to minimize the cross section of the anchoring element and the width required for the hole. The ends of the arms, spaced from the base element, engage an external fastening member thereby providing a solid anchorage in any of a solid, thick or thin hollow wall.

Abstract: An improved fastening element for securement within an opening and of the type comprising (a) a head portion; (b) a connecting portion comprising a longitudinally extending body portion including a pair of opposed pillar-like parts, for insertion into such opening; and (c) at the end of said connecting portion remote from the head portion, locking means movable between a collapsed position in which the fastening element is insertable into the opening and an expanded position in which the locking means is effective in cooperation with an elongated retaining element inserted into the connecting portion to preclude removal of the fastening element from the opening.

The leg may be of any length suitable for their intended use and may be improved by the addition of handle-like projections at the slideably connected end.

Abstract: A container defining an inner containment region and having means for positively sealing and opening at least one end to provide access to the containment region. An enclosure member is provided with at least one closure secured thereto for hinged movement adjacent to the opening, the closure being bi-directionally movable from a locked first position wherein the closure seals the container opening, through an intermediate position to a locked second position wherein the closure positively unseals the opening. The enclosure member resiliently deforms in coopertive interaction with the closure as the closure moves between the first and second positions, respectively, to aid further movement thereof from the intermediate position to either of the first locked closed positiion or the second locked open position. A method for manufacturing the container is also disclosed.
