The present invention provides a linear fastening system capable of rapid engagement and disengagement. More specifically, the system utilizes a cooperating collet member and a compression ring member which are constructed and arranged to slip easily over a shank member. The fastener system is secured by linearly traversing a compression member in an overlapping fashion over the collet member thereby utilizing ribbed surfaces to compress the collet member to grip the outer surface of the shank member. In this manner, the linear fastener system is capable of providing a precise, secure, and reproducible connection between multiple components without the need to apply rotational torque to the assembly.

A seal system is utilized with flat, rough, and/or ribbed wall surfaces and includes a top dock pad and two substantially parallel side dock pads, which substantially frame a doorway at a loading dock. The dock pads are secured to the wall by a plurality of mounting brackets. The dock pads include a first foam layer coupled to a rear portion of a backing structure. The first foam layer operates to accommodate, or substantially “fill-in”, any surface irregularities of the building wall surface, such as a rough wall texture and rib surfaces, to provide an airtight or substantially airtight seal between the building and the seal structure. The dock pads also include a second foam layer coupled to a front portion of the backing structure. The second foam layer is employed to create an effective seal between the building and a rear portion of a vehicle.

The invention relates to the dual face digital controlled machining of complex structures that composed of horizontal beam components, positioned using two holes set on the process boss with compression slot set around the component, horizontally set frame component using one side of two holes to position, two process holes set on the boss which set surrounding the component with rib surface as the positioning face, cushion plate as the tool, using countersunk bolt compressing the fixed plate, horizontal set wall plate components using special vacuum sucking tool, machining from the side with less slot, then regarding it as the positioning baseline. It changes the process complexity of existing techniques. It is simple in locating, stable, simple in compression, good in universality, free from special making, avoiding component deformation, compression damage or dimension precision worsening due to clamp change. It can be co-used with other components with certain universality, economical in tooling.

A retaining system in which straps are provided with hooks that remain engaged with retaining loops even when tension on the straps is released and in which the tightening mechanism includes rods which are located partially below a rib surface on which the straps are placed such that the ends of the rods are near the plane of the strap ends, thereby greatly reducing the bending moment applied to the strap ends and threaded rods. The hook preferably includes a cavity opposite the hook end that will engage the retaining loop when no tension is on the line. In some embodiments, the hook includes a spring-loaded retaining clip to further ensure that the hook does not become disengaged from the retaining loop. The tightening mechanism includes two rods, each of which is positioned to one side of a rib on which the straps rest.
