Abstract

An installation tool for fastening a top plate to a roof support member and other structural connections is adapted to drive threaded fasteners at a pre-established angle. The tool preferably includes a rotary driver assembly and a telescopic tube assembly. A guide head assembly is mounted adjacent the outer end of the telescopic tube assembly. Locating or reference structures function to properly precisely set the drive angle of the fastener. Various indicators mounted to the guide head indicate the flush position of a locating surface or reference structure. The flush indicators may employ a projection, a flag, an LED or an audio module.

First claim

The invention claimed is:

1. A guide head assembly mountable to an installation tool with a torque driver having a fastener coupler comprising:
a frame having a locating end and a non-coplanar locating surface and a fastener channel defining an axis disposed at an angle θ to said locating surface and configured to receive a fastener so that when said locating surface is positioned against the first member, said locating end is positioned adjacent a second member, said fastener is received in said channel and said driver is energized, said fastener coupler engages said fastener and is torqued to drive said fastener through said first member at said angle θ into said second member; and
an indicator module mounted relative to said frame which indicates that the locating surface is flush against said first member.

2. The guide head assembly of claim 1 wherein said indicator module further comprises a spring loaded pin which projects through said locating surface and is depressible to project a flush indicator.

3. The guide head assembly of claim 1 wherein said indicator module comprises a depressible button which projects from said locating surface and an indicator light responsive to said button.

4. The guide head assembly of claim 3 wherein said light is an LED.

5. The guide head assembly of claim 1 wherein said indicator module comprises a flag which is hinged to said frame and is received in the frame in a first position and at least partially pivots out of the frame when the locating surface is in a vertical position.

6. The guide head assembly of claim 1 wherein said indicator module comprises a depressible button which projects from said locating surface and an audio module responsive to said button to emit a sound.

7. A guide head mountable to a fastener installation tool comprising:
a frame having a locating end and a non-coplanar locating surface and a fastener channel defining an axis disposed at an angle to said locating surface and configured to receive a fastener so that when said locating surface is positioned against a first member, said fastener is drivable through said member at said angle; and
a flush indicator disposed on said frame to indicate that the locating surface is flush against said first member.

8. The guide head of claim 7 wherein said flush indicator further comprises a spring loaded pin which projects through said locating surface and is displaceable to project from a surface opposed to said locating surface.

9. The guide head of claim 7 wherein said flush indicator comprises a displaceable actuator which projects from said locating surface and an indicator light responsive to said actuator.

10. The guide head of claim 9 wherein said light is an LED.

11. The guide head of claim 7 wherein said flush indicator comprises a flag which is hinged to said frame in a first position when the locating surface is non-vertical and pivots to a second position when the locating surface is in a vertical orientation.

12. The guide head of claim 7 wherein said flush indicator comprises a displaceable actuator and an audio module responsive to said actuator to emit a sound.

13. The guide head of claim 7 wherein said flush indicator comprises a spring-loaded actuator which actuates a switch.

14. A head assembly mountable to a fastener installation tool comprising:
a frame having a reference structure and a fastener channel defining an axis disposed at an acute angle θ to said reference structure and configured to receive a fastener so that when said reference structure is positioned flush against a first member, said fastener is to drivable through said first member at said angle θ; and
an indicator module which indicates from a location remote from said reference structure that the reference structure is flush against said first member.

15. The head assembly of claim 14 wherein said indicator module further comprises a spring loaded pin which projects through said reference structure and is depressible to project an indicator.

16. The head assembly of claim 15 wherein said indicator comprises an opposed end of said pin.

17. The head assembly of claim 14 wherein said indicator module comprises a depressible button which projects from said reference structure and an indicator light responsive to said button.

18. The head assembly of claim 17 wherein said light is an LED.

19. The head assembly of claim 14 wherein said indicator module comprises a flag which is hinged to said frame and is a first position and is pivotal from a second position when the reference structure is in a vertical position.

20. The head assembly of claim 14 wherein said indicator module comprises a spring-loaded depressible member which projects from said reference structure and an audio module responsive to said depressible member to emit a sound.
