Abstract: The invention provides a portable, collapsible sign stand assembly in which a sign is suspended from a support tube. The support tube is connected to a support base through a connecting member which includes a plurality of weakening members which cause the connecting member to fail upon impact.

Abstract: A sign stand assembly having a message panel and a mast. A mast clamp is coupled to the lower end of the mast and a clevis is coupled to the mast clamp. A resilient support assembly includes a coil spring and a spring mounting adapter threadingly engaged with the upper end of the coil spring. A keyed portion including a mounting surface and a pair of key members upwardly protruding therefrom, comprising a concave socket for receiving the clevis with a close tolerance fit preventing rotation of the clevis.

Abstract: A vehicular barrier post includes an upper tubular portion and a lower tubular stand-off. The upper portion is joined to a rocking base having a tubular bottom portion telescopically received in the stand-off. The upper end of a tension spring is secured to the upper body portion by a pin. The lower end of the spring is attached to a tension member, such as a chain, which passes through the stand-off so as to be received in a hole in a suitable external support. The chain is pulled past the external support and when the spring is appropriately tensioned, a locking pin is passed through the chain, preventing its reverse travel through the external support. The upper body portion is allowed to freely rock about the stand-off.

Abstract: A cable splicer chair is disclosed that is ergonomically sound in a wide variety of work environments. This seat includes a seat assembly having a backrest and adjustable legs that will allow the chair seat to be level regardless of the terrain upon which the chair is supported. The cable splicer chair includes convenient mechanisms for attaching tools that are used by the cable splicer and locating such tools optimally for an individual cable splicer.

Abstract: The invention provides a portable, collapsible sign stand assembly in which a sign is suspended from a support tube. The support tube is connected to a support base through a connecting member which includes a plurality of weakening members which cause the connecting member to fail upon impact. In other embodiments, the support tube is weakened by weakening members so as to fail upon impact. In one embodiment, the weakened portions are placed under tension.

Abstract: A quick release mechanism for a sign stand base having support legs pivotally joined to a support flange. The support legs are notched to receive the support flange. A locking pin extends through the support leg and is positioned so s to selectively interfere with an outer periphery of the support flange. The locking pin is mounted for rocking or swiveling motion within the support leg and can be moved out of contact with the support flange, thereby allowing the support leg to pivot with respect to the support flange. A flat spring strip secured to an outer surface of the support leg biases the locking pin to a position engaging the support flange.

Abstract: A mounting receptacle is provided for securement to a flexible message panel. The mounting receptacle defines a housing for receiving a support rib. A threshold portion is hingedly coupled to the housing portion allowing a rib to contact the threshold portion while the housing portion is bent out of the way of the rib. The rib is telescopically received in the housing portion and, when released, tensions the message panel in a planar message-displaying condition.

Abstract: A releasable coupling assembly for support ribs associated with sign panels, and the like elongated support members. Force generated by a knob and threaded shaft is applied to a pressure plate through a lever arm. The lever arm is arranged so as to provide a reduced mechanical advantage which limits applied force to the rib. The lever arm may also be made resilient to limit force applied to a rib being clamped.

Abstract: A mounting for warning devices includes a body having one or more outwardly extending finger portions. Mounting staffs aligned with the finger portion are secured thereto with a sliding collar which surrounds both the mounting staff and finger portions. The mounting staffs may be pivotally joined to the body, adjacent each finger portion. The body portion may be mounted from an upright support member, secured to a stationary or mobile support.

Abstract: A sign stand provides a resilient mounting for an upstanding mast member. A composite spring extends in a vertical direction and is clamped at its top and bottom ends by respective framework members. The upper framework provides mounting for the upright mast while the lower framework provides mounting for ground-engaging legs.

Abstract: A tripod stand for roadway signs includes three legs pivotally connected to a mounting bracket at their upper ends. A plate is attached to the mounting bracket so that trough-shaped recesses are provided for guiding movement of two of the legs, with the bracket being formed to provide a trough-shaped recess regarding movement of a third leg.

Abstract: A warning device includes a flexible collar of adjustable length so as to be wrapped about a beam, pole or log being transported on a vehicular carrier. The flexible collar includes a serial connection of a rigid mounting base, a tensioning device and a chain. A light fixture, warning flags or other devices can be supported by the rigid mounting base. The flexible collar also includes rigid arms hingedly connected to the mounting base, and preferably shaped in the form of a yoke.

Abstract: A quick release mechanism for locking a tubular leg member to a supporting structure whereby a >-shaped flat metal spring exerts upward pressure on the handle end of a lever arm causing the lower operating end of the lever arm to force a locking pin into the locked position in the supporting structure. The pin is unlocked by pressing down on the handle end of the lever arm. The quick release mechanism may be secured to legs of a supporting device so that the legs can be readily pivoted into a number of positions, particularly an extended position for support and a spaced parallel arrangement for storage.

Abstract: An upright mast is affixed to a horizontal support which is pivotally mounted on a horizontal shaft seated in a mounting base whereby abutting resilient members, such as springs, concentric with the shaft separately resist pivotal deflection in opposite directions of said mast on its supporting base.

Abstract: An upright mast for a sign, and the like, is pivotally mounted upon a base and shaft with two adjustable resilient members, such as springs, mounted between the base and mast for separately resisting pivotal deflection in opposite directions.

Abstract: The invention provides a portable, collapsible sign comprised of a flexible, durable panel secured to a frame of four arms pivotally attached to a rigid central web so as to fold down one direction only and form a compact bundle for storage. The arms in the extended position are in the form of a cross and hold the sign panel firmly extended. The portable sign can be quickly assembled and disassembled.
