Abstract
The present invention discloses a lightweight sign-support assembly for displaying and supporting a sign in a preselected display position. The sign-supporting assembly is especially adapted for ground-access removal, installation, or changing of signs or messages in elevated pole banner-type signs. The sign supporting assembly includes a track secured to a pole, a support assembly slidably secured in the track, and a locking mechanism for positioning and releasably securing the support assembly along the track.
Claims18
A sign-supporting device for supporting and displaying a sign at a preselected display position on a surface of an object, said sign-supporting device comprising:
- a track including a pair of opposed elongated channels spaced laterally apart from one another, and a track discontinuity on said track;
- track mounting means for securing said track to the surface of the object;
- at least one slider having an inner base disposed at an inner position between said elongated channels and an outer flange portion protruding outwardly generally away from said inner base and said track, said innerbase being received within said opposed elongated channels for sliding movement therein in a longitudinal direction along said track, said inner base further having an opening therein;
- a support arm for supporting the sign thereon, said support arm having an inner end and being interconnected with said slider for sliding movement therewith relative to said track to and from the preselected display position, said support arm being pivotally interconnected with said outer flange portion of said slider for pivotal movement relative thereto between an extended position protruding generally transversely away from said track and a retracted position oriented generally longitudinally adjacent said channels said support arm further being movably interconnected with said outer flange portion of said slider for limited movement toward and away from said pivotal interconnection therewith, said inner end of said support arm being receivable within said opening in said inner base when said support arm is in said extended position and is moved toward said pivotal interconnection in order to retain said support arm in said extended position, said support arm being removed from said opening in an inner base when said support arm is moved away from said pivotal interconnection in order to allow said pivotal movement between said extended and retracted positions;
- and
- a locking member interconnected with said slider, said locking member being interlockingly and selectively releasably engageable with said track discontinuity on said track when said slider and said support arm are slidably moved to the preselected display position in order to releasably secure said slider and said support arm in said preselected display position.

- track mounting means for securing said track to the surface of the object;
- at least one slider received within said opposed elongated channels for sliding movement therein in a longitudinal direction along said track, said slider including a slider discontinuity defining a slider opening therein;
- a support arm for supporting the sign thereon, said support arm being interconnected with said slider for sliding movement therewith relative to said track to and from the preselected display position, said support arm being pivotally interconnected with said slider for pivotal movement relative thereto between an extended position protruding generally transversely away from said track and a retracted position oriented generally longitudinally adjacent said channels, said support arm having at least one protuberance thereon interlockingly and selectively releasably engageable with said slider opening when said support arm is pivoted to said retracted position;
- a pivot pin extending through said support arm and fixed to said slider for pivotally interconnecting said support arm with said slider, said pivot pin being received within an elongated opening in said support arm in order to allow limited movement of said support arm toward and away from said pivot pin, said support arm further including resilient arm biasing means for resiliently biasing said support arm inwardly toward said pivot pin, said slider including a cam portion extending into said slider opening from a laterally outer portion thereof, said cam portion urging said support arm to move generally away from said pivot pin when said protuberance slidably engages said cam portion as said support arm is moved to and away from said retracted position, said resilient arm biasing means urging said support arm toward said pivot pin when said protuberance is out of engagement with said cam portion;
- and
- a locking member interconnected with said slider, said locking member being interlockingly and selectively releasably engageable with said track discontinuity on said track when said slider and said support arm are slidably moved to the preselected display position in order to releasably secure said slider and said support arm in said preselected display position.
