Abstract

Abstract A traffic marker in which an upright column carrying reflectors is supported in a molded rubber base. The traffic marker is comprised of a secure assembly of three resilient parts, each one of which is easily replaceable in case of damage. The upright column is a resilient tubing having a flared lower end. The molded rubber base has a slightly conical opening, with an annular recess on its under surface. A resilient rubber bellows is snugly received through the base opening, and snugly receives the flared lower end of the tubular column in its upper opening. The bellows functions as a hinge member, and also as a secure assembly member. The lower portion of the bellows is shaped as a frustum of a cone closely received in the base opening, said cone being provided with an external annular shoulder mating with the annular recess on the underside of the base, and providing positive location for the bellows. The upper portion of the bellows has an interior conical surface mating with the flared lower end of the tubular column, and an internal annular shoulder for seating the flared lower end of the column.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 204 words
A traffic marker which includes: a tubular column having sufficient vertical extent, diameter, and reflectance, to be conspicuous to motorists, said column having an outwardly flared lower end; a normally vertical holder for said column, said holder comprising: a sleeve at the upper end of said holder for closely receiving said flared lower end of said column; a bellows comprising a series of bellows folds below said upper sleeve, said bellows having a resilience permitting the deflection of said sleeve from the vertical axis of said holder; and a lower end of said holder having greater horizontal extent than the diameter of said bellows, said lower end having walls diverging outwardly and downwardly, and said lower end including a peripheral shoulder at its lowermost edge; and a base having sufficient horizontal extent and weight relative to said holder and said column to support them in a normally upright vertical position with stability, and said base being provided with an opening for receiving said lower end of said holder, said opening having upward converging interior walls to mate with the downwardly diverging walls of said lower end, and said base opening having an internal peripheral recess to accommodate said lower peripheral shoulder on said holder.
Claim 2
Dependent Claim 204 words
A traffic marker which includes: a tubular column having sufficient vertical extent, diameter, and reflectance, to be conspicuous to motorists, said column having an outwardly flared lower end; a normally vertical holder for said column, said holder comprising: a sleeve at the upper end of said holder for closely receiving said flared lower end of said column; a bellows comprising a series of bellows folds below said upper sleeve, said bellows having a resilience permitting the deflection of said sleeve from the vertical axis of said holder; and a lower end of said holder having greater horizontal extent than the diameter of said bellows, said lower end having walls diverging outwardly and downwardly, and said lower end including a peripheral shoulder at its lowermost edge; and a base having sufficient horizontal extent and weight relative to said holder and said column to support them in a normally upright vertical position with stability, and said base being provided with an opening for receiving said lower end of said holder, said opening having upward converging interior walls to mate with the downwardly diverging walls of said lower end, and said base opening having an internal peripheral recess to accommodate said lower peripheral shoulder on said holder.
Claim 3
Dependent Claim 94 words
A traffic marker as described in claim 1 in which said holder is formed substantially as an upwardly converging cone, said lower end of said holder being an annular shoulder of substantially larger diameter than said bellows and said sleeve, said bellows diminishing in diameter at each successive fold in an ascending direction, and said sleeve having an internal conical surface accommodating the flared lower end of said column and said sleeve being provided, near its lower end, with an internal annular shoulder for supporting and locating said flared lower end of said column.
