DETAILED DESCRIPTION OF THE INVENTION

[0019] FIGS. 1 through 4 show a prying device 10 in accordance with a first embodiment of the present invention includes a body 20 being a one-piece structure. The body 20 includes a first structural section 21 and a second structural section 22. The second structural section 22 is connected to the first structural section 21 axially along an axis L.

[0020] The first structural section 21 has a longitudinal length determining a lever arm length of the prying device 10. The first structural section 21 includes first and second surfaces 211 and 212 and first and second lateral sides 213 extending lengthwise along the axis L. The first and second surfaces 211 and 212 are disposed oppositely. The first and second lateral sides 213 are disposed oppositely and each extends from the first surface 211 to the second surface 212. The first surface 211 is a flat level surface. The second surface 212 curves into a concave shape in a direction transverse to the axis L. The first and second lateral sides 213 are flat level surfaces. The first structural section 21 is quadrilateral in cross-section. The first and second surfaces 211 and 212 are spaced apart from one another in a thickness of the first structural section 21. The first structural section 21 has a first thickness D1 defining a maximum thickness thereof and a second thickness D2 defining a minimum thickness thereof respectively. The second thickness D2 is less than 0.9 times of the first thickness D1. The second thickness D2 is greater than 0.75 times of the first thickness D1.

[0021] The second structural section 22 is adapted to insert underneath an object to be pried by the prying device 10. The second structural section 22 includes third and fourth surfaces 221 and 222 and third and fourth lateral sides 223 extending lengthwise along the axis L. The third and fourth surfaces 221 and 222 are disposed oppositely. The third and fourth lateral sides 223 are disposed oppositely and each extends from the third surface 221 to the fourth surface 222. The first and third surfaces 211 and 221 are juxtaposed and on the same side of the body 20. The second and fourth surfaces 212 and 222 are juxtaposed and on the same side of the body 20.

[0022] The body 20 includes a bend between the first and second structural sections 21 and 22 and when the first structural section 21 is disposed horizontally on a surface an end of the second structural section 22 which is distal to the first structural section 21 is at a higher height from the surface than another end which is adjacent to the first structural section 21.

[0023] A grip 23 is coupled to the first structural section 21. The second structural section 22 and the grip 23 are on opposite ends of the first structural section 21. The grip 23 is of made of a material which allows a user to grasp comfortably and which has a less hardness than a hardness of the body 20.

[0024] Each of the third and fourth lateral sides 223 is tapered and which includes a wider end adjacent to the first structural section 21 and a narrower end distal to the first structural section 21. Each of the third and fourth lateral sides 223 protrudes above the fourth surface 222.

[0025] Furthermore, the second structural section 22 includes an inclined surface which inclines from the second surface 212 to the fourth surface 222 and which extends lengthwise along the axis L. Each of the third and fourth lateral sides 223 protrudes above the inclined surface.

[0026] FIGS. 5 and 6 show a prying device in accordance with a second embodiment of the present invention, and the same numbers are used to correlate similar components of the first embodiment, but bearing a letter a. The second embodiment differentiates from the first embodiment in that a first surface 211a also curves into a concave shape in a direction transverse to the axis L. Furthermore, the first surface 211a and a second surface 212a are spaced apart from one another in a thickness of a first structural section, the first structural section has a first thickness D1 defining a maximum thickness thereof and a second thickness D2 defining a minimum thickness thereof respectively, and the second thickness D2 is less than 0.8 times of the first thickness D1. Moreover, the second thickness D2 is greater than 0.6 times of the first thickness D1.

[0027] In view of the forgoing, the prying devices are built to withstand high stress tensile working loads during prying operations and, accordingly, the second surfaces 212 and 212a have concave shapes, and the first and third surfaces 211, 211a and 221 are juxtaposed, as well as the second and fourth surfaces 212, 212a, and 222 are juxtaposed.
