A centerline clamp assembly sized to insert into an end aperture of a pipe structure, characterized by two or more symmetrically-formed linkages interoperably connected in series, with each of these linkages comprising respective opposing toggle joints pivotally joined at their inner ends to a shared common linkage assembly and at their outer ends by a respective first linkage assembly and a second linkage assembly, with each linkage assembly defining a respective bore configured to concurrently receive an actuating shaft in position along a common geometric centerline axis of the pipe. Multiple alternative configurations may be used in which the number of linkages and linkage assemblies may be increased to achieve clamping action at multiple locations in a pipe structure, thus varying the clamping force according to the properties of the pipe. The configuration and number of linkage assemblies may serve as mounting platforms for instruments, tools, and/or accessories.

Centerline clamp assembly and associated systems and methods

A sports helmet with a full fabric brim. The helmet protects the skull from impact while the brim provides sun protection to the face, ears, neck, and upper shoulders. The helmet consists of a bowl-shaped, thin-walled, protective shell. The shell contains tear shaped vent holes in the crown and circular vent holes in the front and rear. The shell padding consists of closed cell foam pads in the front, rear, and crown. The helmet is secured by a four-point strap and is closed with a plastic snap buckle. A full fabric brim is attached to the inner edge of the shell with hook and loop strips. The shell padding is secured to the inner lining of the brim band with hook and loop strips. The brim band sandwiched between the shell and the padding provides a very secure attachment. The brim is constructed of heavy duty fabric that is pliable yet maintains its shape in extreme conditions. The material actually stiffens slightly when wet, making it ideal for water sports. The brim will give upon impact so a blow is distributed evenly across the surface of the shell.
