Abstract
The present invention is a manual nailing tool configured to provide a user with improved functional advantages over prior art hammers. It manually drives a substantial or predetermined amount of a fastener, such as an 8.89 cm (3½ inch) common nail, into a work piece with one hand using one striking action. The unique configuration of the integrally formed nail-starter and angled strike face closely combines the nail-starter function with a full force, sustained first strike on the nail head. The hammer is also configured with a unique head shape and strike face to improve striking power and facilitate a stronger and more direct impact force on the nail head.
Claims13
A hammer (36) comprising:
- a handle (38), the handle having an upper handle portion (40), and a lower handle portion (42):
- and a head (37) disposed on the upper handle portion (40);
- the head (37) having a centrally configured head body (62) that is integrally formed with the upper handle portion,
- wherein the head (37) is comprised of a curved and tapering nail-starter strike face neck (46) of a predetermined length,
- wherein the nail-starter strike face neck has a nail-starter strike face (48), configured at a predetermined angle and the lower portion of the nail-starter strike face neck (46) further extends as a horizontal cylinder segment (50),
- wherein is configured a groove and magnet (54) to arrange and affix a nail thereon, a semi-circular nail head opening (58) configured to receive the nail head in a position parallel to the nail-starter strike face (48), and
- wherein the horizontal cylinder segment (50) includes a convex strike face (52) in both horizontal and vertical directions, characterized in that a chamfer (53) is disposed along the edges of the strike face (52);
- and
- wherein the adjacent end of the hammer (36) head (37) is configured with a bell neck (66) and bell (68), wherein the bell (68) includes a convex bell strike surface (70) in both horizontal and vertical directions, characterized in that a chamfer (71) is disposed along the edges of the strike face;
- and a bifurcated claw nail remover (64) disposed on top of the head (37)
the hammer (36) of any one of the preceding claims, wherein a generally round shaped, angled nail-starter strike face (48) of a predetermined diameter is configured with a substantial amount of the head (37) mass and weight disposed directly behind said strike face (48)
the hammer (36) of any one of the preceding claims, wherein a nail groove and angled nail-starter strike face (48) are configured to make and sustain a full force initial strike on the full area surface of a nail head
the hammer (36) of any one of the preceding claims, wherein the head (37) is laterally offset a predetermined distance toward the rear relative to the vertical center of the lower handle portion (42)
the hammer (36) of any one of the preceding claims, wherein an upper handle portion (40) is configured with an I-shape cross-sectional profile which includes front and rear flanges, and a center web
the hammer (36) of any one of the preceding claims, wherein a curved head (37) is constructed and arranged whereby the horizontal center axis aligns with a typical arcing swing plane of the user when driving a nail into a work piece
the hammer (36) of any one of the preceding claims, wherein a nail-starter strike face is angled preferably between 75 and 85 degrees relative to the arcing horizontal center axis of the tapering strike face neck
the hammer (36) of any one of the preceding claims, wherein a handle (38) is disposed with a covering of different material (e.g., an elastomer material) on top of the metal shaft, therein configured with textured areas such as indents or ridges on the front and rear
the hammer (36) of any one of the preceding claims, wherein a head (37) is configured with a reduced bifurcated claw for nail removal disposed on the top most portion of the head (37) so as to utilize the top surface of the extended strike face neck (46) as a fulcrum
the hammer (36) of any one of the preceding claims, is configured with a v-shaped nail shaft groove (60) whereby the nail shaft support walls are angled to form a 60 degree vertical wedge.
the hammer (36) of any one of the preceding claims, wherein a v-shaped nail shaft groove (60) is configured with a recessed magnet (54) whereby the perimeter of said magnet is disposed a short distance, preferably 6 mm, from the nail-starter strike face (48)
