Sliding Mechanism
Abstract
A sliding mechanism includes a fixed member and a movable
member. The fixed member has a first end provided with a first stop
member and a second end provided with two second stop members. The
movable member has a first end provided with two first limit
members and a second end provided with a second limit member. The
two first limit members protrude outwardly from the first end of
the fixed member when the movable member is movable forward, and
the second limit member protrudes outwardly from the second end of
the fixed member when the movable member is movable backward, so
that the two opposite ends of the movable member are movable to
protrude outwardly from the two opposite ends of the fixed member
so as to increase the movement distance of the sliding
mechanism.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a sliding mechanism and,
more particularly, to a sliding mechanism for a drawer and the
like.
[0003] 2. Description of the Related Art
[0004] A conventional sliding mechanism comprises a fixed member
and a movable member movably mounted on the fixed member. The fixed
member has a front end provided with a front stop rib and a rear
end provided with a rear stop rib. The movable member has a rear
end provided with a limit rib that is movable to abut the front
stop rib or the rear stop rib of the fixed member to limit the
movable member on the fixed member. However, the movable member can
protrude outwardly the front end of the fixed member and cannot
protrude outwardly the rear end of the fixed member, thereby
shortening the distance of movement of the sliding mechanism.
BRIEF SUMMARY OF THE INVENTION
[0005] In accordance with the present invention, there is provided
a sliding mechanism, comprising a fixed member and a movable member
movably mounted on the fixed member. The fixed member has a first
end provided with a first stop member and a second end provided
with two second stop members spaced from each other. The movable
member has a first end provided with two first limit members spaced
from each other and a second end provided with a second limit
member.
[0006] The primary objective of the present invention is to provide
a sliding mechanism having a greater distance of movement.
[0007] Another objective of the present invention is to provide a
sliding mechanism, wherein the two first limit members on the first
end of the movable member protrude outwardly from the first end of
the fixed member when the movable member is movable forward
relative to the fixed member, and the second limit member on the
second end of the movable member protrudes outwardly from the
second end of the fixed member when the movable member is movable
backward relative to the fixed member, so that the two opposite
ends of the movable member are movable to protrude outwardly from
the two opposite ends of the fixed member so as to increase the
movement distance of the sliding mechanism.
[0008] A further objective of the present invention is to provide a
sliding mechanism, wherein the movable member is movable relative
to the fixed member in two opposite directions so as to increase
the movement distance of the sliding mechanism, so that the
material of the sliding mechanism can be reduced so as to decrease
the costs of fabrication.
[0009] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0016] Referring to the drawings and initially to FIGS. 1-4, a
sliding mechanism in accordance with the preferred embodiment of
the present invention comprises a fixed member 10 and a movable
member 20 movably mounted on the fixed member 10.
[0017] The fixed member 10 has a first end provided with a first
stop member 11 and a second end provided with two second stop
members 12 spaced from each other. The second end of the fixed
member 10 has a gap 13 defined between the two second stop members
12. The first stop member 11 of the fixed member 10 faces and
aligns with the gap 13 of the fixed member 10. The first stop
member 11 of the fixed member 10 is located at a height between the
two second stop members 12.
[0018] The movable member 20 has a first end provided with two
first limit members 21 spaced from each other and a second end
provided with a second limit member 22. The first end of the
movable member 20 has a spacing 23 defined between the two first
limit members 21. The second limit member 22 of the movable member
20 faces and aligns with the spacing 23 of the movable member 20
and also faces and aligns with the gap 13 of the fixed member 10.
The second limit member 22 of the movable member 20 is located at a
height that is between the two first limit members 21 and is equal
to that of the first stop member 11 of the fixed member 10. The two
first limit members 21 of the movable member 20 face and align with
the two second stop members 12 of the fixed member 10 respectively.
The spacing 23 of the movable member 20 faces and aligns with the
first stop member 11 of the fixed member 10.
[0019] When in use, the second limit member 22 of the movable
member 20 is movable to pass through the gap 13 of the fixed member
10 and is movable to abut the first stop member 11 of the fixed
member 10 as shown in FIG. 4. At the same time, the two first limit
members 21 of the movable member 20 protrude outwardly from the
fixed member 10 when the second limit member 22 of the movable
member 20 is movable to abut the first stop member 11 of the fixed
member 10. In addition, the two first limit members 21 of the
movable member 20 are movable to allow the first stop member 11 of
the fixed member 10 to pass through the spacing 23 of the movable
member 20 and are movable to abut the two second stop members 12 of
the fixed member 10 as shown in FIG. 6. At the same time, the
second limit member 22 of the movable member 20 protrudes outwardly
from the fixed member 10 when the two first limit members 21 of the
movable member 20 are movable to abut the two second stop members
12 of the fixed member 10.
[0020] In operation, referring to FIGS. 4-6 with reference to FIGS.
1-3, when the movable member 20 is movable forward relative to the
fixed member 10 as shown in FIG. 1, the second limit member 22 of
the movable member 20 is movable to pass through the gap 13 of the
fixed member 10 and is movable to abut the first stop member 11 of
the fixed member 10 as shown in FIG. 4 to stop movement of the
movable member 20. On the contrary, when the movable member 20 is
movable backward relative to the fixed member 10 as shown in FIG.
5, the two first limit members 21 of the movable member 20 are
movable to allow the first stop member 11 of the fixed member 10 to
pass through the spacing 23 of the movable member 20 and are
movable to abut the two second stop members 12 of the fixed member
10 as shown in FIG. 6. In such a manner, the two opposite ends of
the movable member 20 are movable relative to the fixed member 10
to protrude outwardly from two opposite ends of the fixed member 10
so as to increase the movement distance of the sliding
mechanism.
[0021] Accordingly, the two first limit members 21 on the first end
of the movable member 20 protrude outwardly from the first end of
the fixed member 10 when the movable member 20 is movable forward
relative to the fixed member 10, and the second limit member 22 on
the second end of the movable member 20 protrudes outwardly from
the second end of the fixed member 10 when the movable member 20 is
movable backward relative to the fixed member 10, so that the two
opposite ends of the movable member 20 are movable to protrude
outwardly from the two opposite ends of the fixed member 10 so as
to increase the movement distance of the sliding mechanism. In
addition, the movable member 20 is movable relative to the fixed
member 10 in two opposite directions so as to increase the movement
distance of the sliding mechanism, so that the material of the
sliding mechanism can be reduced so as to decrease the costs of
fabrication.
[0022] 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.
