Abstract
A transportable support base for supporting a vertical post such as roadway sign support post in a vertical position. The transportable support base has a weighted platform having a flat bottom wall. A through slot extends from a side wall of the platform and terminates in a central region of the platform. At least a flat bottom wall has a high coefficient of friction for frictional adherence to a surface for resisting to lateral and uplifting forces applied thereto. A handle hole is disposed adjacent two opposed sides of the weighted platform and accessible from above or thereunder for manipulating the support base.
Description
TRANSPORTABLE SUPPORT BASE
TECHNICAL FIELD
The present invention relates to a transportable support base of the type typically utilized in road construction for supporting vertical posts to which are secured road signs or other members associated with road security such as barriers, rails, etc.
The transportable support base is of the type which comprises a weighted platform having a through slot therein for anchoring a post having a foot plate which is positioned under the through slot and wherein the bottom of the platform has a high co-efficient of friction for adherence to a surface for resisting to forces transferred thereto through the post.
BACKGROUND ART
A problem that exists with transportable support bases of the above type is that these bases are usually constructed as rectangular bases with a slot extending longitudinally therein and terminating substantially at the center of the support base.
Adjacent one of the opposed transverse ends, there is provided a through hole which constitutes a handle. In order to transport these weighted platforms which can weigh between 30 and 50 lbs, a worker person must grasp the platform from above the handle hole and hinge the platform outwardly with the arm triceps displaced 90 , or substantially parallel to the ground, to lift it, thus applying the weight of the platform to the triceps arm muscle and the elbow region. During a day, a worker can lift several of these support bases whereby to move them or to remove them from a construction site.
Such manipulation causes muscle, bone and even back injury.
Another disadvantage of these transportable support bases is that they are usually improperly stacked particularly during transport where the stack may be subjected to all sorts of disturbances as a transport vehicle travels over rough terrain and they are usually strewn all over the surface area of the box of the vehicle carrying these support bases. Still further, when these support bases are stacked one on top of the other, a user person can only grab the handle of the uppermost support base of the stack as the handle holes of the bases under the top one are not accessible.
SUMMARY OF INVENTION
It is a feature of the present invention to provide a transportable support base, of the above type, and which substantially overcomes all of the above-mentioned disadvantages.
