Some embodiments of the disclosure provide a locking connector and a sheet material. According to an embodiment, the locking connector includes a locking base body. An annular protrusion is arranged at the middle portion of the locking base body while connecting protrusions are arranged on two sides. The two connecting protrusions are symmetrically located on two sides of the annular protrusion. A mounting groove is arranged between the connecting protrusion and the annular protrusion. The connecting protrusions, the mounting grooves, and the annular protrusion are used for clamping the sheet materials. The sheet materials are mounted, enclosed, and locked tightly in a plurality of directions.

Embodiments are directed to a helmet. The helmet preferably includes a shell, a suspension, and a connector. The suspension preferably includes a crown strap. The connector preferably couples to the shell and the crown strap. The connector preferably has a shock absorber operatively disposed between the shell and the crown strap to absorb at least a portion of a force of impact delivered to the shell.

A holder for flexible materials which incorporate two arms connected by an elbow. Within the elbow is a tensioning mechanism which, when engaged, tends to press the arm apart. When the tension is released, the holder collapses into an easily stored mechanism. With the arms being variable in length, the range of material dimensions is greatly enhanced. A connector positioned at the elbow permits the holder to be secured to a base and arranged in gangs to address the particular need at the time.

A multi-orientation attachment apparatus constructed of molded silicone or another form of elastomeric substance and configured to be selectively coupled to a variety of hospital surfaces. Embodiments of the present disclosure may include two or more pairs of elongated members being configured to be selectively coupled to a circumference, for instance, a hospital bed rail or an IV pole, at a first end and selectively coupled to form a loop at a second end.

A fastener includes a self-locking pin washer and at least one elongate projection mounted on the self-locking pin washer, where the self-locking pin washer is arranged to be a resistance fit to a projection mounted on a structure or vehicle. A method of fastening a panel to a substrate includes attaching a fastener to a projection of a substrate, wherein the fastener includes an elongate projection that is longer than the projection. The method further includes attaching a panel onto the elongate projection of the fastener.

A clip for fixing an agricultural ground sheet cover material, or a netting, in place comprises two inter-engageable parts, each part having a jaw at one end for gripping sheet material or netting between the jaws when the two inter-engageable parts are closed together, a locking tab on one of the inter-engageable parts, a locking bar on the other of the inter-engageable parts, and and cord engaging formations at an opposite end of at least one of the inter-engageable clip parts, adapted to grip a cord between the cord engaging formations to lock the cord to the clip.

A number of magnetically assisted latch mechanisms are presented, where the latching and unlatching action is done with reduced user effort, therefore promoting speed and efficiency without sacrificing the strength of the bond of the connected components. The latching mechanisms are designed to secure panels or other similar small and large mostly flat components. The latching method is done by a rotating component that takes all the separating load once rotated into the locked position. The rotatable lock, or hammer, is also locked itself into position to prevent accidental movement by the hammer.

A clip having superimposable parts for securing, between the parts, thin pliable materials, at any locations on the material, adjacent the material edges or at any position between opposing material edges.

Embodiments are directed to a helmet. The helmet preferably includes a shell, a suspension, and a connector. The suspension preferably includes a crown strap. The connector preferably couples to the shell and the crown strap. The connector preferably has a shock absorber operatively disposed between the shell and the crown strap to absorb at least a portion of a force of impact delivered to the shell.

A board apparatus is presented. The board apparatus includes an elongate body having an upper groove and a back portion lip, a removable elongate member configured for placement within the upper groove, and a screen. The screen includes a lower end configured to fit in the upper groove and below the back portion lip. The apparatus is useful for providing easy installation and removal of windows and screens.
