DETAILED DESCRIPTION OF THE INVENTION
[0021] Referring to the drawings and initially to FIGS. 1-5, a
wrench rack in accordance with the preferred embodiment of the
present invention comprises a main body 1, a mounting frame 21
mounted on the main body 1, a plurality of locking units 22 mounted
on the mounting frame 21, a plurality of wrenches 4 mounted on the
mounting frame 21 and detachably locked onto the locking units 22
respectively, and a plurality of magnetically attractive members 3
mounted on the main body 1.
[0022] The mounting frame 21 is mounted on a first side of the main
body 1. The mounting frame 21 has a substantially U-shaped profile
and has two opposite sides each provided with the locking units 22
for mounting the wrenches 4. The mounting frame 21 has a periphery
provided with a plurality of fixing holes 211.
[0023] Each of the locking units 22 includes two opposite flexible
clamping plates 221, and each of the wrenches 4 is clamped between
the two clamping plates 221 of each of the locking units 22. Each
of the locking units 22 has a clamping space 223 defined between
the two clamping plates 221 to clamp the respective wrench 4. Each
of the two clamping plates 221 of each of the locking units 22 is
inclined relative to a surface 210 of the mounting frame 21. The
two clamping plates 221 of each of the locking units 22 are
inclined toward each other, so that the clamping space 223 of each
of the locking units 22 has a tapered shape and has a dimension
decreased gradually from the surface 210 of the mounting frame 21
to a distal end 224 of each of the two clamping plates 221 to clamp
the respective wrench 4 tightly and closely.
[0024] Each of the magnetically attractive members 3 is mounted on
a second side of the main body 1. Preferably, each of the
magnetically attractive members 3 is a magnet. Each of the wrenches
4 is a T-shaped wrench.
[0025] The main body 1 has an endless shape. The main body 1 has an
end portion provided with an upright handle 11. The handle 11 of
the main body 1 has an inner portion provided with a through hole
111 and two opposite magnetic members 112 surrounding the through
hole 111. The through hole 111 and the two magnetic members 112 of
the main body 1 form a magnetizing portion 110. The handle 11 of
the main body 1 has a periphery provided with a demagnetizing
portion 113. The demagnetizing portion 113 of the main body 1 is
located outside of and aligns with the through hole 111 and one of
the two magnetic members 112. The first side of the main body 1 has
a periphery provided with a plurality of screw bores 13, and the
wrench rack further comprises a plurality of locking screws 14
respectively extending through the fixing holes 211 of the mounting

main body 1 to attach mounting frame 21 to the main body 1. The
second side of the main body 1 has a periphery provided with a
plurality of mounting holes 12 for mounting the magnetically
attractive members 3 respectively.
[0026] In operation, the main body 1 is attached to a metallic
surface on a working place by the magnetically attractive members 3
to facilitate a user identifying and operating the wrench rack. In
such a manner, each of the wrenches 4 can be removed from the two
clamping plates 221 of each of the locking units 22 for use. At
this time, each of the wrenches 4 can be inserted into the through
hole 111 of the main body 1 so that each of the wrenches 4 is
magnetized by the two magnetic members 112 of the main body 1 to
have a magnetic feature so as to magnetically attract a metallic
workpiece, such as a screw, bolt and the like. On the contrary,
when each of the wrenches 4 touches the demagnetizing portion 113
of the main body 1, each of the wrenches 4 is demagnetized to
eliminate its magnetic feature.
[0027] As shown in FIG. 6, each of the wrenches 4a is a hex
wrench.
[0028] Accordingly, the clamping space 223 of each of the locking
units 22 has a tapered shape to clamp the respective wrench 4, so
that each of the wrenches 4 is clamped tightly and closely by the
elastic actions of the two clamping plates 221 of each of the
locking units 22 so as to facilitate packaging and storage of each
of the wrenches 4. In addition, the main body 1 has magnetizing and
demagnetizing functions to facilitate a user magnetizing and
demagnetizing each of the wrenches 4 and to facilitate the user
operating each of the wrenches 4. Further, the main body 1 is
attached to a metallic surface on a working place by the
magnetically attractive members 3 to facilitate a user identifying
and operating the wrench rack.
[0029] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the true
scope of the invention.
