Abstract
Abstract A portable traffic marker characterized by a horizontal roadengaging base member and a vertical standard normally extending upwardly from the base. The standard is operatively connected to the base member by a plurality of peripherally spaced and radially extending elastic cords. The base is relatively heavy and is capable of remaining in a stable condition on the ground even under high wind conditions or when run over by a moving vehicle. The resilient connection between the base and standard permits the latter to readily move between its normal upright or vertical position downwardly to a generally horizontal position when acted upon by outside forces, and without effecting movement of the base.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
110 words
A portable traffic marker including a relatively flat groundengaging base member having a central opening extending vertically therein, a separate vertical standard disposed centrally of said central opening and extending upwardly therefrom, a plate-like member secured to said standard adjacent the lower end thereof, a plurality of resiliently extensible means connected to and extending under tension from the periphery of the central opening of said base member to the lower end of said standard to support said standard above the ground, whereby said standard may be deflected by a moving object from said vertical position to an inclined position relative to said base member and restored to said vertical position.
Claim 2
Dependent Claim
110 words
A portable traffic marker including a relatively flat groundengaging base member having a central opening extending vertically therein, a separate vertical standard disposed centrally of said central opening and extending upwardly therefrom, a plate-like member secured to said standard adjacent the lower end thereof, a plurality of resiliently extensible means connected to and extending under tension from the periphery of the central opening of said base member to the lower end of said standard to support said standard above the ground, whereby said standard may be deflected by a moving object from said vertical position to an inclined position relative to said base member and restored to said vertical position.
Claim 3
Dependent Claim
34 words
A marker as set forth in claim 1 in which said resiliently extensible means include a plurality of elastic cord members extending radially outwardly from said standard to said periphery of said central opening.
Claim 4
Dependent Claim
18 words
A member as set forth in claim 2 in which said standard is of a hollow conical configuration.
Claim 5
Dependent Claim
19 words
A member as set forth in claim 2 including said elastic cord members being attached to said plate-like member.
Claim 6
Dependent Claim
52 words
A member as set forth in claim 4, including a plurality of rigid elements disposed within said base member around said opening, said elastic cord members being attached to said elements and extending into said opening generally normal to said standard and being attached to peripherally spaced portions of said plate-like member.
