Abstract
A pulling tool for pulling nails, screws, rivets, pegs, or other protrusions includes a jaw which may be opened to receive the head of the protrusion. The jaw is then at least partially closed against the protrusion, and when the handle of the tool is pulled, the jaw is both urged shut and also away from the surface from which the protrusion extends. Thus, as the protrusion is pulled, its shaft is also more tightly grasped, which helps to pull the protrusion from the surface without stripping off its head/cap. The pulling tool can be provided as a part of a hammer, crowbar, or other conventional tool.
Claims26
A pulling tool for pulling out embedded nails and other protruding objects, the pulling tool comprising:
- a. a tool head having:
- (1) a tool head bottom from which a handle extends, and
- (2) a tool head top bearing an anchor thereon, the anchor being situated at least partially along the axis of the handle;
- b. a jaw having:
- (1) a pivot about which the jaw pivots with respect to the anchor, the pivot being spaced from the axis of the handle;
- (2) a bearing surface extending from a jaw tip to a jaw tail;
- (3) a cutout extending through the jaw from the bearing surface, the cutout being:
- (a) situated between the jaw tip and the jaw tail, and
- (b) bounded on one side by a jaw grasping face;
- wherein the jaw pivots between:
- A. a closed state wherein the anchor rests closely adjacent the jaw grasping face, whereby a nail or other protrusion may be grasped between the anchor and the jaw grasping face;
- and
- B. an open state wherein the jaw grasping face is spaced from the anchor to define a mouth therebetween, whereby a nail or other protrusion may be inserted into or removed from the mouth.
A pulling tool for pulling out embedded nails and other protruding objects, the pulling tool comprising:
- a. a tool head including:
- (1) a tool head top with an anchor thereon, and
- (2) a tool head bottom adapted to receive a hammer head or hammer handle;
- b. a jaw including:
- (1) a bearing surface extending adjacent the tool head top and opposite the tool head bottom from a jaw grasping face to a jaw tail, wherein the jaw grasping face faces toward the jaw tail;
- (2) a pivot whereby the jaw pivots with respect to the anchor between:
- (i) an open state wherein a mouth is defined:
- 1) upon the bearing surface, and
- 2) adjacent the jaw grasping face,
- whereby a nail or other protrusion may be fit into the mouth;
- and
- (ii) a closed state wherein the mouth is at least substantially closed, whereby the mouth may be closed about the nail or other protrusion, and wherein the anchor does not extend past the bearing surface;
- and
- (3) a cutout extending through the jaw from the bearing surface, wherein the anchor is pivotally mounted within the cutout, the cutout being:
- (i) situated between the jaw tip and the jaw tail, and
- (ii) bounded on one side by the jaw grasping face, wherein the mouth is defined between the anchor and the jaw grasping face.
A pulling tool for pulling out embedded nails and other protruding objects, the pulling tool comprising:
- a. a tool head defined by a hammer head having a striking head and an opposing claw, the tool head having:
- (1) a tool head bottom, wherein a hammer handle is attached or attachable to the tool head bottom to extend at a fixed orientation therefrom, and
- (2) an opposing tool head top bearing an anchor, the anchor being situated between the striking head and the claw;
- c. a jaw pivotally affixed to the tool head wherein:
- (1) the jaw includes a bearing surface curving in an arc:
- (a) away from the pivot to a jaw tail, and
- (b) along planes perpendicular to the axis about which the jaw pivots,
- the bearing surface being adjacent the tool head top and opposite the tool head bottom;
- (2) the jaw is pivotable between:
- (a) an open state wherein a mouth is defined between the jaw and the anchor, whereby a nail or other protrusion may be fit into the mouth, and
- (b) a closed state adjacent the anchor, whereby the mouth may be closed about the nail or other protrusion and wherein the anchor does not extend past the bearing surface.
A pulling tool for pulling out embedded nails and other protruding objects, the pulling tool comprising:
- a. a tool head having:
- (1) a tool head bottom, wherein a hammer handle is attached or attachable to the tool head bottom to extend at a fixed orientation therefrom, and
- (2) an opposing tool head top bearing an anchor;
- c. a jaw pivotally affixed to the tool head, wherein:
- (1) the jaw includes a bearing surface:
- (a) adjacent the tool head top and opposite the tool head bottom;
- (b) having a cutout defined therein, with a portion of the cutout being bounded by the jaw grasping face;
- (c) curving in an arc:
- (i) away from the pivot to a jaw tail, and
- (ii) along planes perpendicular to the axis about which the jaw pivots,
- (2) the jaw is pivotable between:
- (a) an open state wherein a mouth is defined between the grasping face of the jaw and the anchor, whereby a nail or other protrusion may be fit into the mouth, and
- (b) a closed state adjacent the anchor, whereby the mouth may be closed about the nail or other protrusion, and wherein the anchor does not extend past the bearing surface.
