Abstract:
1. A framing hammer assembly, the framing hammer assembly for driving and removing nails within tight spaces, the framing hammer assembly comprising a three-dimensional hammer head, an elongate hammer handle, and a select tool attachment assembly, the hammer head inherently extending along an x-y plane, a y-z plane, and an x-z plane and comprising first and second nail-striking heads, a fulcrum, a nail-pulling claw, and a handle-receiving aperture, the first nail-striking head having a first head axis, the second nail-striking head having a second head axis, the nail-pulling claw comprising a nail-receiving groove, the fulcrum having at least two fulcrum dimensions, the handle-receiving aperture having a tunnel axis, the first head axis extending through a first strike plane defined by the x-z plane, the second head axis extending orthogonally to the first strike plane in a second strike plane defined by the y-z plane, the nail-receiving groove extending in mirrored relation about the x-z plane, the fulcrum extending substantially parallel to the y-z plane intermediate the nail-pulling claw and the handle-receiving aperture, the tunnel axis being substantially collinear with a z-axis, the hammer handle comprising a handle axis, a first handle end, a second handle end, a head-engagement portion, an outer handle surface, female fastener-receiving structure, and male alignment structure, the fastener-receiving structure having an aperture axis and the alignment structure having a protrusion axis, the aperture and protrusion axes being coplanar with the y-z plane, the handle-engaging portion comprising an attachment aperture and an alignment aperture, the alignment aperture receiving the alignment structure, the attachment aperture being centered about the aperture axis, the outer handle surface comprising a hand-grip portion and distance-measurement means for measuring distances via the outer handle surface, the first handle end and the head-engagement portion being received in the handle-receiving aperture such that the tunnel axis is substantially collinear with the handle axis, the measurement indicia being located intermediate the head-engagement portion and the hand grip portion, the hand-grip portion extending intermediate the measurement indicia and the second handle end, the select tool attachment assembly comprising a select tool accessory and handle attachment-means for fastening the select tool accessory to the second handle end, the select tool accessory comprising a planar handle-engaging end portion, a substantially planar nail-removing end portion, and a substantially planar end-connecting portion, the handle-engaging end portion being parallel to the x-y plane and the nail-removing end portion being parallel to the x-z plane, the end-connecting portion being integrally formed with the handle-engaging and nail-removing end portions, the nail-removing end portion being cooperable with a driven nail for enabling the removal thereof, the handle attachment means for attaching the select tool accessory to the second handle end via the fastener-receiving structure, the select tool accessory being interchangeable with a plurality of secondary tool accessories, the second nail-striking head and the hammer handle for enabling the user to drive nails within tight spaces, the select tool attachment assembly and the hammer handle for providing a lever arm and for enabling the user to remove driven nails within tight spaces.
