## Background
BACKGROUND OF INVENTION
1. Field of Invention
The present invention relates to a hanger for a wrench.
2. Related Prior Art
Referring to FIG. 12, a conventional hanger includes a board 100 and a hollow joint 200. The board 100 includes a slot 104 defined at an end thereof for hanging a wrench 300 to a wall. The board 100 includes a rod 102 formed thereon. The rod 102 includes teeth 103 formed at a periphery thereof. The hollow joint 200 includes a hexagonal periphery and a substantially cylindrical internal wall. Teeth (not shown) are formed on the internal wall of the hollow joint 200. The teeth of the joint 200 match the teeth 103 of the rod 102 so that the hollow joint 200 can be engaged with the board 100. A wrench 300 includes a box end 302 and a ring 301 received in the box end 302. The wrench 300 can be hung on the hollow joint 200. The hanger is however complicated structurally and involves complicated fabrication and results in a high cost. Furthermore, a user cannot try the wrench 300 on the hanger.
The present invention is therefore intended to obviate or at least alleviate the problems encountered in the prior art.
SUMMARY OF INVENTION
The primary objective of the present invention is to provide a structurally simple hanger for a wrench.
A hanger is disclosed for a wrench. The wrench includes a head and an insert connected with the head. The hanger includes a board and an aperture defined in the board for receiving the insert of the wrench. The edge of the aperture can hold the insert in position because of friction.
The primary advantage of the hanger of the present invention is structural simplicity. Another advantage of the hanger of the present invention is that a user can test the wrench on the hanger.

DETAILED DESCRIPTION OF EMBODIMENTS
FIGS. 1 to 3 show a hanger according to a first embodiment of the present invention. A selective one-way wrench 20 can be hung on the hanger.
The hanger includes a board 10, a slot 13 defined in an end thereof and an aperture 14 defined in an opposite end thereof.
The selective one-way wrench 20 includes a box end 24. A square insert 21 is attached to the box end 24. The square insert 21 includes four corners 22 formed thereon. Although not shown as being conventional, a selective one-way driving mechanism is provided between the square insert 21 and the box end 24. In a first mode, the box end 24 can drive the square insert 21 in a first direction, but not vice versa. In a second mode, the box end 24 can drive the square insert 21 in a second direction opposite to the first direction.
The diameter D1 of the aperture 14 is marginally smaller than the diagonal distance W of the square insert 21. Thus, the square insert 21 can be forced and retained in the aperture 14.
Referring to FIG. 4, the wrench 20 is in the second mode. Friction between the edge of the aperture 14 and the corners 22 is adequate to hold the square insert 21 in position when the wrench 20 is rotated in the first direction relative to the board 10.
Referring to FIG. 5, the friction between the edge of the aperture 14 and the corners 22 is inadequate to hold the square insert 21 in position when the wrench is rotated in the second direction.
FIG. 6 shows a hanger according to a second embodiment of the present invention. The second embodiment is identical to the first embodiment except for several things. Firstly, fingers 15 project from a side of the board 10 for holding the square insert 21 of the wrench 20. Secondly, each of the fingers 15 includes a boss 19 formed thereon for contact with the square insert 21 of the wrench 20. Thirdly, each of the fingers 15 is an elastomer.
FIG. 7 shows the wrench 20 attached to the hanger. The bosses 19 extend from the fingers 15 for an adequate distance so that adjacent two of them can pinch one of the corners 22.
FIG. 8 shows a hanger according to a third embodiment of the present invention. The third embodiment is identical to the first embodiment except for several things. Firstly, the hanger includes a cambered slot 16 defined in an end thereof opposite to the slot 13. Secondly, a restraint 17 is connected with the wrench 20 on one hand and inserted in the cambered slot 16 on the other hand.
FIG. 9 shows a hanger according to a fourth embodiment of the present invention. The fourth embodiment is identical to the first embodiment except for including a restraint 18 formed at an end of the board 10 opposite to the slot 13. The restraint 18 may be a strap with two ends connected with the board 10 for restraining the wrench 20 between the restraint 18 and the board 10.
FIGS. 10 and 11 show a hanger according to a fifth embodiment of the present invention. The fifth embodiment is identical to the first embodiment except for including a retaining board 30 and a restraint 36. The retaining board 30 includes a first portion 31, a second portion 33 extending obliquely from the first portion 31 and a third portion 32 extending substantially perpendicularly from the second portion 33. The first portion 31 includes a bore 34 defined therein. The third portion 32 includes two apertures 35 defined therein. The diameter D2 of the bore 34 is larger than the diagonal distance W of the square insert 21 of the wrench 20. The bore 34 is aligned with the aperture 14 so that the square insert 21 can be inserted into the bore 34 through the aperture 14.
FIG. 11 shows the board 10 located between the wrench 20 and the retaining board 30. The restraint 36 includes two ends each including a bolt (not shown) for engagement with a nut (not numbered). The restraint 36 is used for restraining the retaining board 30 to the wrench 20. Thus, the board 10 is firmly attached to the wrench 20 by the retaining board 30.
The present invention has been described through detailed illustration of the embodiments. Those skilled in the art can derive variations from the embodiments. The embodiments hence shall not limit the scope of the present invention defined in the claims.
