Abstract
A sign post system includes an elongated slide spike, and an impact anvil mounted to the slide spike at a location intermediate the spike ends. An elongated slide hammer column assembly slides onto the slide spike to contact the impact anvil while using the slide spike as a guide to deliver a force to the slide spike to drive the slide spike into the ground. A hollow sign post structure is configured to slide over the slide spike and cover at least a portion of the slide spike above the impact anvil, the slide spike and sign post configured to support a sign structure after installation. In an exemplary embodiment, the system parts are fabricated of plastic materials.
Claims23
A sign post system, comprising:
- an elongated slide spike having a first end configured to enter the ground for installation, and a second end configured to be disposed above ground after installation;
- an impact anvil mounted to the slide spike at a location intermediate the first and second ends;
- an elongated slide hammer column assembly configured to slide onto the slide spike at the second end, and configured to slide over the slide spike to contact the impact anvil while using the slide spike as a guide to deliver a force to the slide spike to drive the slide spike first end into the ground, the slide hammer column assembly configured for manual use by a user to lower and raise the slide hammer column assembly repeatedly to drive the slide spike into the ground to a desired depth for installation;
- a hollow sign post structure configured to slide over the second end of the slide spike and cover at least a portion of the slide spike above the impact anvil, the slide spike and sign post configured to support a sign structure after installation;
- and
- wherein the hammer column assembly is further configured with the hollow sign post structure such that the hollow sign post structure covers the hammer column assembly as well as the portion of the slide spike after installation.
