that the quick release connecting device and the second object 6
are rotatably connected to each other.
[0055] In the first preferred embodiment shown in FIGS. 1 to 9, the
receiving space 11 in the actuating retainer 1 includes a straight
and rectangular-sectioned slide space 111. The inner end of the
body portion 21 of the fixing member 2 is extended into the slide
space 111 and is slidably held therein via the pin connection means
3, so that the actuating retainer 1 and the fixing member 2 are
able to slide relative to each other within a limited range. The
elastic element 4 is preferably a coil spring, as shown in FIGS. 2
to 6, but it can also be an elastic plate or an elastic bar. The
elastic element 4 is disposed in the slide space 111 with an end
pressed against an inner wall surface of the slide space 111 and
another end pressed against the body portion 21, such that the
actuating retainer 1 and the fixing member 2 can slide relative to
each other within a limited range and then return to their
respective original position under the elastic force of the elastic
element 4.
[0056] In the second preferred embodiment shown in FIGS. 10 to 12,
the receiving space 11 in the actuating retainer 1 includes an
arcuate slide space 112. The inner end of the body portion 21 of
the fixing member 2 is extended into the arcuate slide space 112
and is rotatably held therein via the pin connection means 3, so
that the actuating retainer 1 and the fixing member 2 are able to
rotate relative to each other within a limited angle. The elastic
element 4 is preferably a coil spring, as shown in FIG. 10, but it
can also be an elastic plate as shown in FIG. 12 or an elastic bar
(not shown). The elastic element 4 is disposed in the arcuate slide
space 112 with an end pressed against an inner wall surface of the
slide space 112 and another end pressed against the body portion
21, such that the actuating retainer 1 and the fixing member 2 can
rotate relative to each other within a limited angle and then
return to their respective original position under the elastic
force of the elastic element 4.
[0057] The first object 5 can be a rack, a chassis, a cabinet for
drawers, a window frame or other objects; and the second object 6
can be a circuit board, a drawer, a window or other objects. FIG.
13A shows the quick release connecting device according to the
first preferred embodiment of the present invention is movably
assembled to the second object 6 via the pivot portion 22 of the
fixing member 2. Meanwhile, the retaining section 12 of the
actuating retainer 1 and the second push section 23 of the fixing
member 2 are detachably engaged with two opposite sides of the
first object 5, so that the second object 6 is located in and
sidewardly movably connected to the first object 5 via the quick
release connecting device. When it is desired to separate the
second object 6 from the first object 5, as indicated by FIG. 13B,
simply push the first push section 14 of the actuating retainer 1
with one hand, so that the actuating retainer 1 slides toward the
fixing member 2 by a limited range to separate the retaining
section 12 from one side of the first object 5. Then, as shown in
FIG. 13C, utilize the principle of leverage to push the quick
release connecting device for the fixing member 2 to rotate about
the pivot portion 22, bringing the second push section 23 to push
the other side of the first object 5 away from it. At this point,
the second object 6 can be pulled to slide out of the first object
5. Finally, as shown in FIG. 13D, when the second object 6 is
separated from the first object 5 and the first push section 14 is
no longer subjected to a push, the elastic element 4 automatically
pushes the actuating retainer 1 to slide relative to the fixing
member 5 back to its original position.
[0058] FIG. 14A shows the quick release connecting device according
to the second preferred embodiment of the present invention is
similarly movably assembled to the second object 6 via the pivot
portion 22 of the fixing member 2. Meanwhile, the retaining section
12 of the actuating retainer 1 and the second push section 23 of
the fixing member 2 are detachably engaged with two opposite sides
of the first object 5, so that the second object 6 is located in
and sidewardly movably connected to the first object 5 via the
quick release connecting device. When it is desired to separate the
second object 6 from the first object 5, as indicated by FIG. 14B,
simply push the first push section 14 of the actuating retainer 1
with one hand, so that the actuating retainer 1 rotates relative to
the fixing member 2 by a limited angle to separate the retaining
section 12 from one side of the first object 5. Then, as shown in
FIG. 14C, utilize the principle of leverage to push the quick
release connecting device for the fixing member 2 to rotate about
the pivot portion 22, bringing the second push section 23 to push
the other side of the first object 5 away from it. At this point,
the second object 6 can be pulled to slide out of the first object
5. Finally, as shown in FIG. 14D, when the second object 6 is
separated from the first object 5 and the first push section 14 is
no longer subjected to a push, the elastic element 4 automatically
pushes the actuating retainer 1 to rotate relative to the fixing
member 5 back to its original position.
[0059] The present invention has been described with some preferred
embodiments thereof and it is understood that many changes and
modifications in the described embodiments can be carried out
without departing from the scope and the spirit of the invention
that is intended to be limited only by the appended claims.
