ADAPTER FOR A FASTENER DRIVING TOOL
A fastener driving tool and an adapter for a fastener driving tool are described herein for permitting accurate placement of fasteners with respect to an edge of a board (e.g., a top edge of a siding board). The adapter may include an adapter body having a central opening for receiving a head of a fastener driving tool and two or more pins positioned in the adapter body. At least two of the pins are positioned in the adapter body such that, when the central opening receives the head, the pins are equidistant from a center of a barrel through which the fastener driving tool drives fasteners.
1 . An adapter for a fastener driving tool, the adapter comprising:
an adapter body having a central opening for receiving a head of a fastener driving tool; and
only three pins positioned in the adapter body, wherein the three pins are positioned in the adapter body such that, when the central opening receives the head, the three pins are equidistant from a center of a barrel through which the fastener driving tool drives fasteners.
2 . The adapter of claim 1 , wherein:
the adapter body comprises an upper tab, a first tab on a first side of the upper tab, and a second tab on a second side, opposite the first side, of the upper tab; and
the three pins comprise an upper pin positioned in the upper tab, a first pin positioned in the first tab, and a second pin positioned in the second tab.
3 . The adapter of claim 1 , wherein the adapter body comprises machined aluminum.
4 . The adapter of claim 1 , wherein each of the three pins comprises:
a ferrule;
a stud extending through the ferrule; and
a biasing mechanism configured to bias the stud within the ferrule such that a portion of the stud extends out of an end of the ferrule.
5 . The adapter of claim 1 , wherein the adapter body comprises holes, wherein each hole, of the holes, is configured to receive a pin of the three pins.
6 . The adapter of claim 5 , wherein each hole, of the holes, is configured to position an interior edge of a pin of the three pins a target distance from the center of the barrel through which the fastener driving tool drives fasteners.
7 . The adapter of claim 1 , wherein the central opening is configured for receiving differently shaped heads of fastener driving tools.
8 . The adapter of claim 1 , wherein the three pins are positioned in the adapter body such that, when the central opening receives heads of different fastener driving tools, the three pins are equidistant from centers of barrels through which the fastener driving tools drive fasteners.
9 . The adapter of claim 1 , comprising one or more set screws, wherein the adapter body comprises one or more receiving holes for receiving the one or more set screws, and wherein the one or more set screws are configured to be advanced through the one or more receiving holes into contact with the head of the fastener driving tool.
10 . A fastener driving tool, comprising:
a barrel through which the fastener driving tool drives fasteners;
a head, at an end of the barrel, through which the fastener driving tool drives fasteners; and
an adapter positioned on the head, wherein the adapter comprises:
an adapter body having a central opening for receiving the head; and
only three pins positioned in the adapter body, wherein the three pins are positioned in the adapter body such that the three pins are equidistant from a center of the barrel.
11 . The fastener driving tool of claim 10 , wherein the central opening of the adapter body is configured to friction fit onto the head of the fastener driving tool.
12 . The fastener driving tool of claim 10 , comprising an attachment mechanism attaching the adapter body to the head of the fastener driving tool.
13 . The fastener driving tool of claim 10 , wherein adapter body has a thickness configured such that the adapter does not interfere with operation of the fastener driving tool.
14 . The fastener driving tool of claim 10 , wherein the head is integrated with a safety mechanism configured to permit the fastener driving tool to drive a fastener only when the head and the adapter are pressed against a surface.
15 . The fastener driving tool of claim 10 , wherein:
the adapter body comprises an upper tab, a first tab on a first side of the upper tab, and a second tab on a second side, opposite the first side, of the upper tab; and
the three pins comprise an upper pin positioned in the upper tab, a first pin positioned in the first tab, and a second pin positioned in the second tab.
16 . A roofing gun, comprising:
a barrel through which the roofing gun drives roofing nails;
a head, at an end of the barrel, through which the roofing gun drives roofing nails; and
an adapter positioned on the head, wherein the adapter comprises:
an adapter body having a central opening for receiving the head; and
only three pins positioned in the adapter body, wherein the three pins are positioned in the adapter body such that the three pins are equidistant from a center of the barrel.
17 . The roofing gun of claim 16 , wherein:
the central opening of the adapter body is configured to friction fit onto the head; and
the adapter body is attached to the head via one or more welds.
18 . The roofing gun of claim 17 , wherein:
the adapter body comprises an upper tab, a first tab on a first side of the upper tab, and a second tab on a second side, opposite the first side, of the upper tab; and
the three pins comprise an upper pin positioned in the upper tab, a first pin positioned in the first tab, and a second pin positioned in the second tab.
19 . The roofing gun of claim 18 , wherein each of the upper pin, the first pin, and the second pin comprises a spring-loaded plunger configured to be biased such that each of the upper pin, the first pin, and the second pin projects outward from the adapter body parallel to a direction in which the roofing gun drives roofing nails.
20 . The roofing gun of claim 19 , comprising a safety mechanism configured to permit the roofing gun to drive a roofing nail only when the head and the adapter are pressed against a surface.
