Abstract
A device for driving fastening elements, such as nails, staples and the like, includes a magazine extending transversely from a driving unit. A follower is located within the magazine for supplying fastening elements to the driving unit. For filling the magazine with fastening elements, the follower can be secured in a loading position. The follower is secured by a stop pivotally attached to the follower which engages an abutment on the magazine. The follower is released from the loading position by an actuating member movably mounted on the magazine so that it can contact an engagement part on the follower and pivot the stop out of engagement with the abutment.
Claims3
A device for driving fastening elements, includes means for driving the fastening elements in a first direction, a magazine for holding the fastening elements and for delivering the fastening elements to said means, said magazine being elongated in a second direction extending transversely of the first direction and having a first end through which the fastening elements are supplied to said driving means and a second end spaced outwardly from said means, a follower located within said magazine for moving the fastening elements in the second direction toward said first end of said magazine, said follower being displaceable in the second direction outwardly from said driving means to a loading position for placing fastening elements into said magazine, said follower has a stop thereon and said magazine has an abutment so that in the loading position said stop engages said abutment and retains said follower against displacement in the second direction toward said driving means, said follower includes means for pivoting said stop about an axis extending transversely of the second direction, an engagement part on said follower spaced from and in cooperating relation with said stop, and an actuating member movably displaceable on said magazine for contacting said engagement part and pivotally displacing said stop about the axis of said pivot means for releasing said follower out of the loading position, said follower includes a rocking lever having a pair of oppositely directed arms with the end of one arm forming said stop and the end of the other arm forming said engagement part, said follower includes a follower body, said means for pivoting said stop comprises a pivotal joint member forming the pivot axis and articulating said rocking lever to said follower body, said pivotal joint member comprises a connector web attached at one end to said follower body and at the other end to said rocking lever, and said follower body, said connector web and said rocking lever being formed monolithically.
