Pry tool

Abstract

A pry tool includes a body having a base with a through-hole extending along a first axis and a through-slot extending perpendicularly to the first axis. The base has an arcuate bottom face defining a contact point for contacting with a working plan. A second axis intersects with the first axis at an intersection and passes through the contact point. A third axis intersects with the second axis at the center of curvature of the arcuate bottom face. An angle between the second and third axes is 5°-10°. A shank extends from the base along a fourth axis intersecting with the first axis at the intersection. An angle between the second and fourth axes is 15°-25°. A claw member is coupled to the through-slot. A fixing member is securely mounted in the through-hole and abuts against the claw member.

DETAILED DESCRIPTION OF THE INVENTION

(6) With reference to FIGS. 1-5, a pry tool of an embodiment according to the present invention includes a body 10, a claw member 20 connected to the body 10, and a fixing member 30 securely mounted to the body 10. The body 10 includes a base 11 and a shank 12. The base 11 includes a through-hole 111 extending along a first axis A1 and a through-slot 112 extending in a radial direction perpendicular to the first axis A1. The base 11 includes a side located opposite to the shank 12 and having an arcuate bottom face 113. The arcuate bottom face 113 defines a contact point 114 configured for contacting with a working plane P. The working plane P can be a top face of a wooden slat W or any face providing support. A second axis A2 intersects with the first axis A1 and passes through the contact point 114. A third axis A3 intersects with the second axis A2 at an intersection O which can be the center of curvature of the arcuate bottom face 113. An angle between the third axis A3 and the second axis A2 is in a range of 5° 40°. In the embodiment shown, the angle between the third axis A3 and the second axis A2 is 10°. Furthermore, the shortest distance between the arcuate bottom face 113 and the intersection O of the third axis A3 and the second axis A2 is not larger than 25 mm in this embodiment.

(7) The base 11 further includes an inner arcuate face 115 and an outer arcuate face 116 opposite to the inner arcuate face 115. The radius of curvature of the inner arcuate face 115 is larger than the radius of curvature of the outer arcuate face 116. The shank 12 extends from the base 11 along a fourth axis A4 that intersects with the first axis A1 at a common intersection where the second axis A2 intersects with the first axis A1. An angle between the fourth axis A4 and the second axis A2 is in a range of 15°-25°. In the embodiment shown, the angle between the fourth axis A4 and the second axis A2 is 25°.

(8) The claw member 20 includes an intermediate portion 21 and two claws 22 extending from two opposite ends of the intermediate portion 21, respectively. The intermediate portion 21 is coupled in the through-slot 112 of the base 11. The two claws 22 are configured to abut against the working plane P.

(9) The fixing member 30 is securely mounted to the through-hole 111 of the base 11 and abuts against the claw member 20. In this embodiment, the fixing member 30 is riveted in the through-hole 111 and abuts against the intermediate portion 21 of the claw member 20, avoiding the claw member 20 from disengaging from the body 10.

(10) Furthermore, the pry tool of the embodiment according to the present invention can further include a positioning member 40 having a positioning portion 41 and a clamping portion 42 connected to the positioning portion 41. The shank 12 of the body 10 includes a first positioning hole 121 extending along the fourth axis A4. The fixing member 30 includes a second positioning hole 31 extending along the second axis A2. The positioning portion 41 of the positioning member 40 is removably connected to the first positioning hole 121 (see FIG. 1) or the second positioning hole 31 (see FIG. 4). In this embodiment, the clamping portion 42 has U-shaped cross sections for clamping the wooden slat W.

(11) The shank 12 of the body 10 includes a limiting hole 122 extending in a radial direction perpendicular to the fourth axis A4 and intercommunicating with the first positioning hole 121. The positioning member 40 includes a limiting portion 43 removably coupled in the limiting hole 122. Thus, the positioning member 40 can be positioned in the limiting hole 122. Accordingly, when the positioning member 40 is not required, the positioning portion 41 of the positioning member 40 is coupled with the first positioning hole 121. On the other hand, when the positioning member 40 is required, the positioning portion 41 of the positioning member 40 is coupled with the second positioning hole 31 of the fixing member 30, such that the positioning portion 41 of the positioning member 40 extends along the first axis A1. As shown in FIG. 5, in this case, the clamping portion 42 of the positioning member 40 can clamp the wooden slat W, and the operator can apply a force using the body 10 as a fulcrum to thereby press against a to-be-nailed wooden board B (that has been disposed on the wooden slat W) through the claw member 20. Thus, the pry tool of this embodiment provides a function of tightly pressing the wooden board B, which is advantageous when laying a wooden floor.

(12) In view of the foregoing, based on the special angle design of the base 11 and the shank 12 of the body 10 of the pry tool according to the present invention, the operator can apply force easily when the contact point 114 defined by the arcuate bottom face 113 is used as a fulcrum on the working plane P. Furthermore, the positioning member 40 of the pry tool according to the present invention can clamp the wooden slat W, such that the operator can press against the to-be-nailed wooden board B (which has been disposed on the wooden slat W) through the claw member 20.

(13) Although specific embodiments have been illustrated and described, numerous modifications and variations are still possible without departing from the scope of the invention. The scope of the invention is limited by the accompanying claims.
