BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a double-hinge device and, particularly, to a double-hinge device including first and second hinges adapted to be releasably fixed relative to each other.
2. Description of the Related Art
The present invention relates to a plying tool and, particularly, to a plying tool including plying members adapted to be moved to change their arrangements with respect to one another.
TW Pat. No. 1340685 shows a plying tool including two plying members adapted to be adjusted for creating various sized spaces between the two plying member. When the two plying members are placed very near to each other, a space between therebetween is not small.
The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.

DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1 through 8 show a plying tool 10 in accordance with a first embodiment of the present invention. The plying tool 10 includes a main body 20 and a plying member set 30.
The main body 20 extends longitudinally along an axis L. The main body 20 includes a first joining portion 21 and a second joining portion 22 extending transversely to the axis L and disposed on opposite sides of the axis L. The main body 20 includes a handle 23 and a mounting seat 24 with a plying structure 241 pivotally connected with each another. The mounting seat 24 is connected with a rod 25 which includes two ends respectively forming the first and second joining portions 21 and 22. The mounting seat 24 and the rod 25 are connected in a manner that they don't rotate with respect to each other. The mounting seat 24 has a wedge-shaped working end. The plying structure 241 includes two prongs.
The plying member set 30 includes a first and second plying member 31 and 32 movably and releasably connected with the main body 20. The first and second plying member 31 and 32 are mirror images to each other. The first and second plying members 31 and 32 are movable relative to each other and adapted to connect with the main body 20 in a first arrangement with the first plying member 31 connected with the first joining portion 21 and the second plying member 32 connected with the second joining portion 22 respectively, and a second arrangement with the first plying member 31 connected with the second joining portion 22 and the second plying member 32 connected with the first joining portion 21 respectively. FIGS. 7 and 8 show the first and second plying members 31 and 32 in the second arrangement are in a spaced relationship with a smallest gap therebetween. The first and second plying members 31 and 32 respectively include a plying portion 313 and 323 with a surface facing oppositely and disposed on a reference axis C1 and C2. The first and second plying members 31 and 32 respectively have a connecting portion 311 and 321 which is configured to connect with the main body 20 and which is in an offset position from the reference axis C1 and C2 corresponding thereto. The first and second plying members 31 and 32 include the connecting portions 311 and 321 thereof in the form of a through hole. The first and second joining portions 21, 22 each are insertably engaged with the connecting portions 311 and 321 of the first and second plying members 31 and 32. The first and second plying members 31 and 32 respectively include a hole 312 and 322. The first and second joining portions 2122 respectively include a compartment 211 and 221 with an opening at a distal end thereof, a through aperture 212 and 222 extending radially from the compartment 211 and 221, and a retaining mechanism for stopping movement of one of the first and second plying members 31 and 32 including an actuating member 213 and 223 movably disposed in the compartment 211 and 221 and a detent 216 and 226 movably disposed in the through aperture 212 and 222 and movable, in response to movement of the actuating member 213 and 223, to a retaining position extending out of the through aperture 212 and 222 and partially held by the hole 312 and 322 corresponding thereto and a releasing position disengaged from the hole 312 and 322. Each of the actuating members 213 and 223 has an inclined support surface 215 and 225 supporting the detent 216 and 226 corresponding thereto. Each of the actuating members 213 and 223 is urged by an elastic member 214 and 224.
FIGS. 9 and 10 show a plying tool 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 includes a main body 20a. The main body 20a includes a first joining portion 21a and a second joining portion 22a. The main body 20 includes a handle 23a and a mounting seat 24a with a plying structure 241a pivotally connected with each another. The mounting seat 24a is connected with a rod 25a which includes two ends respectively forming the first and second joining portions 21a and 22a. The mounting seat 24a and the rod 25a are connected in a manner that they don't rotate with respect to each other. The mounting seat 24a has a wedge-shaped working end. The plying structure 241a includes two prongs. The second embodiment differentiates from the first embodiment in that the mounting seat 24a is disposed in a standing position and not aligned along the handle 23a, whereas FIG. 1 shows that mounting seat 24 disposed in a lying position.
In view of the forgoing, the first and second plying member 31 and 32 are movable relative to each other, as shown in FIGS. 4 and 6 and adapted to connect with the main body 20 in a first arrangement with the first plying member 31 connected with the first joining portion 21 and the second plying member 32 connected with the second joining portion 22 respectively, as shown in FIGS. 4 and 6, and a second arrangement with the first plying member 31 connected with the second joining portion 22 and the second plying member 32 connected with the first joining portion 21 respectively, as shown in FIG. 7. In this regard, the first and second plying members 31 and 32 can exchange positions. Furthermore, the first and second plying members 31 and 32 in the second arrangement are in a spaced relationship with a smallest gap therebetween. Because the first and second plying members 31 and 32 are specially designed, the smallest gap is smaller than conventional smallest gaps.
The foregoing is merely illustrative of the principles of this invention, and various modifications can be made by those skilled in the art without de parting from the scope and spirit of the invention.
