Abstract

A fastener used to secure a surface layer to a base and a two-stage fastener driver used the drive the fastener into the base. The fastener comprising a non-magnetic fastener body retaining a ferro-magnetic nail. The fastener driver for driving the fastener into the base. The fastener driver having a housing for magnetically retaining the fastener.

Claims

1. A fastener adapted for attachment to a base and comprising:

a non-magnetic fastener body having a hollow tube with an open bore end surrounded by a non-magnetic flange and a closed end sufficiently pointed to penetrate the base when the fastener is attached to the base and wherein proximate the closed end the fastener body includes a side opening in communication with the open bore end through the hollow tube; and

a ferro-magnetic nail extending through the hollow tube from the open bore end proximate to the side opening and having an exposed magnetic portion projecting upwardly beyond the flange for retention of the fastener by a magnetic portion of a fastener driver.

2. The fastener of claim 1 wherein the fastener body includes an integral camming surface proximate the closed end leading from the side opening to the hollow tube, wherein the nail interferes with the camming surface for interferencly securing the nail to the fastener body and for causing the nail to form a hook configuration when the nail is driven against the camming surface and out the side opening.

3. The fastener of claim 2 wherein the integral camming surface is arcuate.

4. The fastener of claim 3 wherein the non-magnetic material for the fastener body is zinc, nylon, or plastic.

5. The fastener of claim 3 wherein the flange includes holes.

6. The fastener of claim 3 wherein the hollow tube includes at least one dimple obstructing the hollow tube for interfering with the nail.

7. A fastener driver for driving a fastener into a base, the fastener comprising a non-magnetic fastener body interferencly secured to a ferro-magnetic nail, the fastener body includes a body portion having a pointed end portion for penetrating the base and a flange, the secured nail including a portion that extends beyond the flange of the fastener body, the fastener driver comprising:

a drive handle connected to a driving rod;

a drive housing enclosing a portion of the driving rod propellable toward the base by grasping the drive handle;

a face on the drive housing that contacts the flange to drive the fastener body into the base when the drive housing is propelled toward the base;

said drive housing enclosing a driving means for driving the nail;

a magnet within an inlet of the drive housing for temporarily magnetically securing a the portion of the nail extending beyond the flange; and

the driving means driving the nail out through a side opening in the pointed end portion of the fastener body in a hook configuration after the fastener body is driven into the base.

8. The fastener driver of claim 7 wherein the driving means includes a weight connected at one side to the driving rod and connected at an opposite side to a driving pin, the weight suspended within a weight cavity of the housing by a spring surrounding the driving pin, the spring providing a biasing force against the weight, wherein the biasing force is overcome by the weight after the fastener body is driven into the base to cause the driving pin to contact the nail for driving the nail out through the side opening in the pointed end portion of the fastener body in the hook configuration.
