Handheld fastener installation guide
A handheld guide for advancing and installing a decking fastener with an elongate track with a rail and an advancement member. The advancement member carries a pivoting pawl with an engagement surface for advancing fasteners forward through the track to an installation position with a frontmost fastener aligned with a screw guide for driving a screw through the frontmost fastener. The rail has a ramp transitioning to a cliff and a lower ledge such that the frontmost fastener is maintained forward of the cliff above the ledge in the installation position. The pawl pivots to disengage from the fasteners when the advancement member moves rearwardly along the track.
1. A guide for advancing and installing a fastener via an elongate securing member, comprising:
an elongate track extending longitudinally from a rear end to a front end, the track comprising a substantially central elongate rail defining an advancement surface; and
an advancement member engaged with and being longitudinally reciprocable along the track; wherein
the advancement member includes a pawl extending from a rear edge to a front edge extending into the track, the pawl being maintained in a pivoting relationship relative to the advancement member about a substantially laterally extending axis, and the advancement member includes a stop proximate the rear edge of the pawl, the stop defining a rotational extent of the pawl in a single rotational direction, and
the rail defines a substantially flat portion that transitions to a front cliff via an intermediate ramp.
2. The guide of claim 1 , wherein front edge of the pawl is biased away from the advancement member toward the rail.
3. The guide of claim 1 , wherein the pawl includes a leading prong defining a leading front edge extending to a leading terminal point and a trailing prong defining a trailing front edge extending to a trailing terminal point.
4. The guide of claim 3 , wherein when the pawl is maintained against the stop, the trailing terminal point is closer than the leading terminal point to the advancement surface of the rail.
5. The guide of claim 3 , wherein the leading prong includes a leading rear edge oblique to the leading front edge and the trailing prong includes a trailing rear edge oblique to the trailing front edge, and when the pawl is maintained against the stop, the leading and trailing front edges are substantially perpendicular to the longitudinal track.
6. The guide of claim 3 , wherein the laterally extending axis is positioned longitudinally forward of the stop and a bias member is positioned longitudinally forward of the axis to bias the prongs toward the rail.
7. The guide of claim 1 , comprising a screw guide positioned proximate the front end of the track for maintaining an elongate securing member in a substantially upright position.
8. The guide of claim 7 , wherein the screw guide maintains an elongate securing member at an angle that is oblique to the rail in the rearward direction.
9. The guide of claim 8 , wherein the elongate securing member is maintained by the screw guide at an approximate angle between 1° and 10° relative to an axis perpendicular to the rail.
10. The guide of claim 1 , comprising a screw guide positioned proximate the front end of the track for maintaining an elongate securing member in a substantially upright position, wherein a frontmost fastener is maintained longitudinally forward of the cliff in an installation position substantially aligned with an upright securing member maintained by the screw guide.
11. The guide of claim 10 , wherein the frontmost fastener is maintained in the installation position via an upward bias from a bias member.
12. The guide of claim 1 , comprising:
a screw guide positioned proximate the front end of the track for maintaining an elongate securing member in a substantially upright position;
the pawl defines an engagement surface for engaging a fastener positioned along the rail in an intermediate position, and
fasteners positioned within the track on the rail engage with the advancement when the advancement member is reciprocated forward along the track causing the fasteners to slide along the rail in a forward direction from the intermediate position to a forward position with a frontmost fastener in an installation position substantially aligned with a securing member maintained by the screw guide, and the advancement member disengages with fasteners positioned within the track when the advancement member is reciprocated rearward, thereby allowing the fasteners positioned within the track to remain in the intermediate or forward position.
13. The guide of claim 12 , wherein the pawl engages a fastener when the advancement member is reciprocated forward and is pivotable about a substantially laterally extending axis via contact with a fastener when the advancement member is reciprocated rearward.
14. The guide of claim 12 , wherein rail defines a front cliff and the advancement member maintains a frontmost fastener longitudinally forward of the cliff in the forward position.
15. The guide of claim 14 , comprising a bias member for biasing the frontmost fastener in an upward direction away from the rail in the forward position.
16. The guide of claim 1 , comprising a bias member for biasing a frontmost fastener in an upward direction away from the rail in an installation position forward of the cliff.
17. A guide for advancing and installing a fastener via an elongate securing member, comprising:
an elongate track extending longitudinally from a rear end to a front end, the track comprising a substantially central elongate rail defining an advancement surface; and
an advancement member engaged with and being longitudinally reciprocable along the track;
a screw guide positioned proximate the front end of the track for maintaining an elongate securing member in a substantially upright position; and
an upward bias member, wherein
the advancement member includes a pawl extending from a rear edge to a front edge extending into the track, the pawl being maintained in a pivoting relationship relative to the advancement member about a substantially laterally extending axis, and the advancement member includes a stop proximate the rear edge of the pawl, the stop defining a rotational extent of the pawl in a single rotational direction, and
a frontmost fastener defines an attachment opening and is maintained via the upward bias member in an installation position with the attachment opening substantially aligned with the securing member being maintained by the screw guide.
18. The guide of claim 17 , wherein the bias member is a collapsed torsion spring.
19. The guide of claim 17 , wherein the track comprises a pair of upper shoulders, and the bias member holds the frontmost fastener against the shoulders in the installation position.
20. The guide of claim 17 , wherein the rail comprises a substantially flat portion that transitions to a front cliff via a ramp with a substantially flat plateau intermediate the ramp and the cliff.
21. The guide of claim 17 , wherein the rail comprises a substantially flat portion that transitions to a front cliff via a ramp, comprising a pair of front shoulders forward of the cliff for providing a front stop against the frontmost fastener in the installation position.
22. The guide of claim 17 , wherein the advancement surface transitions from a substantially flat portion to a front cliff and the installation position of the clip is longitudinally forward of the cliff.
