Abstract

A multipurpose prying tool, which has a handle, a prying head, which is fixedly connected to one end of the handle and has two jaws of different lengths arranged in parallel and a mouth defined between the two jaws and extending from one end of the handle at 90° or about 90°, and a prying tip made in the form of a claw and obliquely extended from the other end of the handle for pulling out nails.

Description

BACKGROUND OF THE INVENTION

(a) Field of the Invention
The present invention relates to a hand tool and more particularly to a multipurpose prying tool, which is practical for holding and turning wooden plates, pulling out nails, and driving in nails.
(b) Description of the Prior Art
Various lumber turning tools are known. U.S. Pat. No. 4,762,303 discloses a lever type tool, which comprises an elongated handle, and a head having two opposed and spaced apart claws projecting in generally the same direction at opposite sides of a space to closely receive a portion of a rectangular cross section of a lumber member. One of the claws at one side of the space is substantially shorter in length than the other of the claws at the opposite side of the space. U.S. Pat. No. 4,826,136 is substantially similar to U.S. Pat. No. 4,762,303 with the exception that the claws have first inner surfaces; one claw has an outward convex outer surface to engage a work surface, and a second inner surface offset relative to the first inner surface thereof and toward the convex outer surface.
The aforesaid two conventional designs can only be used to turn lumbers and to pull out nails. Further, these two designs are not orthopedically engineered. Because the head and the handle are aligned in line, the user must employ much effort when operating the tool to turn a lumber.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances in view. According to one aspect of the present invention, the multipurpose prying tool comprises a handle, a prying head at one end of the handle, and a prying tip at the other end of the handle. In one embodiment of the present invention, the prying tip is made in the form of a claw and curved from one end of the handle for pulling out nails. Further, the prying head has a mouth extending from one end of the handle at right angle or substantially right angle for holding and turning wooden plates.
According to another aspect of the present invention, two protruding blocks are bilaterally provided in the mouth so that the mouth can be used to hold and turn wooden plates of different thicknesses.
According to still another aspect of the present invention, the prying tip curves outwards to fit a right-handed user, or inwards to fit a left-handed user.
According to still another aspect of the present invention, the prying head has a face at one side for driving in nails.
According to still another aspect of the present invention, the prying tip has a nail-prying hole for pulling out nails, and a beveled work edge on the distal end. Alternatively, the prying tip has a nail-prying hole and a V-notch for pulling out nails.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1˜3, a multipurpose prying tool in accordance with the present invention is shown comprising a handle 1, a prying head 2 at one end of the handle 1, and a prying tip 3 at the other end of the handle 1.
The handle 1 is a long bar having an I-shaped cross section. Further, an anti-slip grip 11 may be bonded to the periphery of the handle 1 (see FIGS. 4 and 5).
The prying head 2 comprises a long jaw 211, a short jaw 212, and a mouth 21 defined between the long jaw 211 and the short jaw 212. The mouth 21 extends from one end of the handle 1 at right angle or substantially right angle. The long jaw 211 and the short jaw 212 each have parallel teeth 221 or 222 arranged on the inner side and facing the mouth 21. The long jaw 211 has one end, namely the fixed end, joined with the fixed end of the short jaw 212 to the handle 1, and the other end, namely the free end, provided with a V-notch 23 for pulling out nails. Further, the long jaw 211 has a face 24 at one side of the fixed end for driving in nails, etc.
The prying tip 3 according to the embodiment shown in FIG. 1 is a claw curved from one end of the handle 1 opposite to the prying head 2, having a sloping face 31, which extends outwards toward a reversed direction relative to the user (right-handed user), and a V-notch 32 on the free end of the sloping face 31 for pulling out nails.
FIG. 6 shows an alternate form of the prying tip 3. According to this embodiment, the prying tip 3 is a flat tip having a nail-pulling hole 34 cut through the top and bottom sides thereof on the middle for pulling out nails and the free end thereof terminating in a beveled working edge 33.
FIG. 7 shows another alternate form of the prying tip 3. According to this embodiment, the prying tip 3 is a flat tip having a nail-pulling hole 34 cut through the top and bottom sides thereof on the middle for pulling out nails and the free end thereof terminating in a V-notch 32 for pulling out nails.
Further, the prying tip 3 can be curved from the handle 1 toward an outer side to fit a right-handed user (see FIG. 1), or toward an inner side to fit a left-handed user (see FIG. 8).
FIGS. 9˜11 show an alternate form of the prying head. According to this embodiment, the prying head 2 a has two blocks 251 and 252 respectively provided in the mouth 21 a at two sides so that the prying head 2 a can be operated to hold and turn wooden plates 41 and 42 of different thicknesses.
A prototype of multipurpose prying tool has been constructed with the features of FIGS. 1˜11. The multipurpose prying tool functions smoothly to provide all of the features disclosed earlier.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
