Abstract
A fastener insertion device includes an actuator that is either pneumatic or manually operated. The fastener insertion device is illustratively configured to receive either a staple magazine or a stake magazine. The stake magazine can house stakes of different dimensions. The pneumatic actuator includes a charging chamber and a control apparatus. The control apparatus comprises two valves, and is disposed between the charging chamber and a pneumatic cylinder.
Claims20
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.
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.
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.
