Fastener insertion device

1. A kit for inserting a fastener into a substrate, the kit comprising

a guide,

a fastener holder couplable to the guide and configured to hold a plurality of fasteners,

a fastener pusher coupled to the guide for movement relative to the fastener holder between a retracted position and an extended fastener-inserting position, the fastener pusher being configured to engage an end of a fastener,

a pneumatic actuator couplable to the guide, the pneumatic actuator being driven by compressed gas to move the fastener pusher between the extended fastener-inserting position and the retracted position, and

a manual actuator couplable to the guide, the manual actuator being manually operable to move the fastener pusher from the retracted position to the extended fastener-inserting position.

2. The kit of claim 1 , wherein the fastener holder is exchangeable with a second fastener holder.

3. The kit of claim 1 , wherein the manual actuator includes a handle and an operator-driven piston coupled to the handle.

4. The kit of claim 1 , wherein the pneumatic actuator includes a control apparatus, and the control apparatus includes a pneumatic valve.

5. The kit of claim 4 , wherein the control apparatus includes two pneumatic valves.

6. The kit of claim 5 , wherein the two pneumatic valves have a first default position and a second position.

7. The kit of claim 6 , wherein the pneumatic actuator is actuated when the two pneumatic valves are both in their second position.

8. A fastener insertion kit for inserting fasteners in a substrate or in the ground, the insertion kit comprising:

a guide,

a magazine couplable to the guide, the magazine being configured to hold a plurality of fasteners and having an opening through which the fasteners are fed;

a drive member coupled to the guide, the drive member being moveable in a first direction across the opening of the magazine to drive a fastener into the substrate or the ground, and moveable in an opposite second direction across the opening,

a pneumatic actuator couplable to the guide, the pneumatic actuator being operable to move the drive member in the first direction, and

a manual actuator couplable to the guide, the manual actuator being manually operable to move the drive member in the first direction.

9. The kit of claim 8 wherein the pneumatic actuator includes:

a pneumatic cylinder having an upper portion and a lower portion, the pneumatic cylinder being in fluid communication with a source of compressed gas; and

a piston having an upper end and an opposite lower end, the piston being disposed within the cylinder and moveable relative thereto, and the piston being coupled to the drive member.

10. The kit of claim 9 wherein the pneumatic actuator further comprises a charging chamber in fluid communication with both the source of compressed gas and with the pneumatic cylinder.

11. The kit of claim 10 wherein the pneumatic actuator further comprises a control apparatus in fluid communication with the charging chamber and the pneumatic cylinder and configured to control the introduction of compressed gas into the pneumatic cylinder.

12. The kit of claim 11 wherein the control apparatus is disposed between the charging chamber and the pneumatic cylinder.

13. The kit of claim 12 wherein the control apparatus comprises a first valve configured to direct compressed gas into the upper portion of the pneumatic cylinder to drive the piston in the first direction and a second valve configured to direct compressed gas into the lower portion of the pneumatic cylinder to drive the piston in the second direction.

14. The kit of claim 13 , wherein both valves must be actuated in order to move the piston in the pneumatic cylinder.

15. The kit of claim 14 , wherein the valves comprise buttons which are actuated by applying pressure thereto.

16. The kit of claim 8 , wherein the magazine is removable and is configured to house fasteners of different dimensions.

17. The kit of claim 16 , wherein the fasteners comprise staples.

18. The kit of claim 16 , wherein the fasteners comprise stakes.

19. The kit of claim 8 wherein the manual actuator includes:

a handle coupled to the drive member and operable alone or with the aid of the compressed gas to move the drive member in the first direction, and

a spring bias disposed between the handle and the drive member and operable alone or with the aid of the compressed gas to move the drive member in the second direction.

20. A fastener insertion kit for inserting fasteners in a substrate or in the ground, the insertion kit comprising:

a guide,

a magazine couplable to the guide, the magazine being configured to hold a plurality of fasteners and having an opening through which the fasteners are fed;

a drive member coupled to the guide, the drive member being moveable in a first direction across the opening of the magazine to drive a fastener into the substrate or the ground, and moveable in an opposite second direction across the opening,

a pneumatic actuator couplable to the guide, the pneumatic actuator including:

a pneumatic cylinder having an upper portion and a lower portion, the pneumatic cylinder being in fluid communication with a source of compressed gas;

a piston having an upper end and an opposite lower end, the piston being disposed within the cylinder and moveable relative thereto;

the drive member being coupled to the piston and moveable therewith in the first direction across the opening of the magazine by the compressed gas entering the upper portion of the pneumatic cylinder to drive a fastener into the substrate or the ground, and moveable in an opposite second direction across the opening by the compressed gas entering the lower portion of pneumatic cylinder, and

a manual actuator couplable to the guide, the manual actuator being manually operable to move the drive member in the first direction.
