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.
Claims20
A pulling tool for pulling out embedded nails and other protruding objects, the pulling tool comprising:
- a. a tool head extending between:
- (1) a tool head top terminating in an anchor, and
- (2) an opposing tool head bottom, wherein the tool head bottom defines an elongated handle;
- b. a jaw pivotably and non-translatably affixed to the tool head top, the jaw including:
- (1) a jaw bearing surface extending from a jaw tip to a jaw tail,
- (2) a cutout extending through the jaw from the jaw 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 with respect to the tool head between:
- A. a closed state wherein the anchor rests at least substantially entirely within the cutout 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 extending between:
- (1) a tool head top, the tool head top having an anchor bearing surface and an adjacent anchor grasping face with an anchor grasping edge defined therebetween, and
- (2) a tool head bottom from which an elongated handle extends;
- b. a jaw having a jaw bearing surface and an adjacent jaw grasping face with a jaw grasping edge defined therebetween;
- c. a pivot rotatably joining the jaw to the tool head, whereby the jaw pivots with respect to the tool head between:
- (1) an open state wherein a mouth is defined between the anchor grasping face and the jaw grasping face, whereby a nail or other protrusion may be fit into the mouth;
- and
- (2) a closed state wherein the mouth is at least substantially closed, with the anchor bearing surface and jaw bearing surface together defining a surface oriented at least substantially tangentially to a plane extending radially from the pivot,
- wherein:
- A. the anchor bearing surface and the jaw bearing surface are adjacently situated to define a surface oriented at least substantially tangentially to a plane extending radially from the axis about which the jaw pivots;
- B. the anchor grasping face and the jaw grasping face are adjacently situated upon or closely adjacent to the plane extending radially from the axis about which the jaw pivots,
- when the jaw is in the closed state.
A pulling tool for pulling out embedded nails and other protruding objects, the pulling tool comprising:
- a. a tool head which:
- (1) extends between an elongated tool handle and an opposing anchor bearing surface, and
- (2) includes an anchor grasping face adjacent the anchor bearing surface, the anchor grasping face being laterally bounded by anchor grasping face sides;
- wherein the tool head has decreasing width as it extends away from the anchor bearing surface and the anchor grasping face,
- b. a jaw pivotally affixed to the tool head wherein:
- (1) the jaw includes:
- (a) a jaw bearing surface, and
- (b) an adjacent jaw grasping face laterally bounded by grasping face sides;
- (2) the jaw is pivotable along a laterally-extending axis between:
- (a) an open state wherein a mouth is spaced between the jaw grasping face and the anchor grasping face, whereby a nail or other protrusion may be fit into the mouth, and
- (b) a closed state wherein:
- (i) the jaw grasping face and the anchor grasping face are closely adjacently situated, whereby the mouth may be closed about the nail or other protrusion, and
- (ii) the anchor grasping face sides and jaw grasping face sides are at least substantially aligned.
