Field of the Invention
[0001] The present invention relates to a slide rail assembly. More particularly, the present
invention relates to a slide rail assembly whose first rail is connected with a correction
mechanism for correcting errors in differential movement of a running carriage relative
to a second rail.
Background of the Invention
[0002] Generally, slide rail assemblies are used with drawers and the like. Such a slide
rail assembly typically includes a first rail, a second rail longitudinally displaceable
relative to the first rail, and a running carriage mounted between the first rail
and the second rail. The running carriage serves to carry the second rail and facilitate
displacement of the second rail relative to the first rail. When the second rail is
displaced relative to the first rail, the running carriage is moved relative to the
second rail in a differential manner; that is to say, the distance by which the running
carriage is displaced is a specific proportion of the distance by which the second
rail is displaced. However, precise differential movement is not always guaranteed.
Errors may occur in differential movement of the running carriage relative to the
second rail.

U.S. Patent No.7,309,115 B2, disclose a pull-out guide assembly for drawers, wherein the pull-out guide assembly
includes a support rail (1), a pull-out rail (2), and a running carriage (3) movably
mounted between the support rail (1) and the pull-out rail (2). The running carriage
(3) can be differentially moved relative to the pull-out rail (2) between a front
end position and a rear end position. Also, the running carriage (3) is mounted with
a stop device for correcting errors in differential movement of the running carriage
(3) relative to the rails.
Summary of the Invention
[0005] The present invention relates to a slide rail assembly according to claim 1. In the
slide rail assembly a correction mechanism is connected to a first rail and can correct
errors in differential movement of a running carriage relative to a second rail.
[0006] According to one aspect of the present invention, a slide rail assembly includes
a first rail, a second rail, a running carriage, a correction mechanism, and an actuator.
The second rail can be longitudinally displaced relative to the first rail. The running
carriage is slidably mounted to the first rail, carries the second rail, and can be
moved together with the second rail in a differential manner with respect to the second
rail. The correction mechanism includes a base connected to the first rail and a pushing
member movably connected to the base, wherein the pushing member can be displaced
between a horizontal position and an inclined position. The actuator is connected
to the second rail and corresponds to the pushing member at the horizontal position.
The pushing member at the horizontal position is able to be driven by the actuator
to displace to the inclined position and hence displace the running carriage to a
position.
[0007] According to another aspect of the present invention, a slide rail assembly for use
with a cabinet having a drawer includes a first rail, a second rail, a third rail,
a running carriage, a pushing member, and an actuator. The first rail is mountable
to the cabinet. The second rail is movably mounted between the first rail and the
third rail and can be longitudinally displaced relative to the first rail. The third
rail carries the drawer. The running carriage is slidably mounted to the first rail,
carries the second rail, and can be moved together with the second rail in a differential
manner with respect to the second rail. The pushing member is movably connected between
the first rail and the second rail and can be displaced between a horizontal position
and an inclined position. The actuator is connected to the second rail and corresponds
to the pushing member at the horizontal position. The pushing member at the horizontal
position is able to be driven by the actuator to displace to the inclined position
and hence displace the running carriage to a position. The pushing member is movably
connected to the first rail, either directly or via a base.
[0008] According to still another aspect of the present invention, a slide rail assembly
includes a first rail, a second rail, a running carriage, a pushing member, and an
actuator. The second rail can be longitudinally displaced relative to the first rail.
The running carriage is slidably mounted to the first rail, carries the second rail,
and can be moved together with the second rail in a differential manner with respect
to the second rail. The pushing member is movably connected to the first rail and
can be displaced between a horizontal position and an inclined position. The actuator
is connected to the second rail and corresponds to the pushing member at the horizontal
position. The pushing member at the horizontal position is able to be driven by the
actuator to displace to the inclined position and hence displace the running carriage
to a position.
[0009] The second rail is longitudinally displaceable relative to the first rail between
a retracted position and an extended position. Should an error occur in differential
movement of the running carriage, the actuator drives the pushing member while the
second rail is displaced from the retracted position toward the extended position;
consequently, the pushing member is displaced from the horizontal position to the
inclined position and displaces the running carriage so as to correct the error. The
actuator releases the pushing member once the pushing member is at the inclined position.
[0010] In some embodiments of any of the above aspects, the actuator is integrally formed
with the second rail.
[0011] In some embodiments of any of the above aspects, the running carriage carries the
second rail via at least one roller.
[0012] The base further includes a horizontal portion and an inclined portion inclined with
respect to the horizontal portion, and the pushing member can be displaced between
the horizontal portion and the inclined portion. The pushing member further includes
at least one contact portion so that, when the pushing member is displaced relative
to the base, the at least one contact portion is in contact with one of the horizontal
portion and the inclined portion of the base.
[0013] The first rail comprises a horizontal portion and an inclined portion inclined with
respect to the horizontal portion, and the pushing member is displaceable between
the horizontal portion and the inclined portion. The pushing member further comprises
at least one contact portion for contact with one of the horizontal portion and the
inclined portion of the first rail when the pushing member is displaced relative to
the first rail.
[0014] One of the advantageous features of employing the present invention is that the correction
mechanism on the first rail can correct differential movement errors of the running
carriage with respect to the second rail, if any.

Detailed Description of the Invention
[0016] Referring to FIG. 1, the slide rail assembly 20 in an embodiment of the present invention
is applied to a cabinet 22 having a drawer 24. The drawer 24 can be pushed into and
pulled out of the cabinet 22 via the slide rail assembly 20.
[0017] FIG. 2 shows the slide rail assembly 20 in an extended state. The slide rail assembly
20 includes a first rail 26, a second rail 30, and a third rail 32. The first rail
26 is mounted to the cabinet 22 via a mounting portion 28. The second rail 30 is movably
mounted between the first rail 26 and the third rail 32. The second rail 30 and the
third rail 32 can be longitudinally displaced relative to the first rail 26. The third
rail 32 serves to carry the drawer 24. A correction mechanism 34 is connected to the
first rail 26. The correction mechanism 34 in this embodiment is connected to the
first rail 26 at a position adjacent to an end portion of the first rail 26 by way
of example only and not as a limitation. As the correction mechanism 34 is connected
to the first rail 26, the correction mechanism 34 can be viewed as a part of the first
rail 26.
[0018] FIG. 3 and FIG. 4 show the first rail 26, the second rail 30, and the third rail
32 in an exploded view and an assembled view respectively. A running carriage 36 is
slidably mounted to the first rail 26 and is configured for carrying the second rail
30. The running carriage 36 includes at least one roller 38 (or ball) for carrying
the second rail 30 and facilitating displacement of the second rail 30 relative to
the first rail 26. In addition, an actuator 40 is connected to the second rail 30.
The actuator 40 can be, but is not limited to, a projection or a bar-like member.
In some embodiments, the actuator 40 is integrally formed with the second rail 30
and can be viewed as a portion of the second rail 30. When an error occurs in differential
movement of the running carriage 36 relative to the second rail 30, the actuator 40
can be operated to drive a portion of the correction mechanism 34 in order for this
portion of the correction mechanism 34 to correct the error of the running carriage
36, as explained in more detail below.
[0019] As shown in FIG. 5, the correction mechanism 34 includes a base 42 and a pushing
member 44. The base 42 can be connected (mounted) to and thus fixed in position on
the first rail 26 or be integrally formed with the first rail 26. The pushing member
44 corresponds to and is movably connected to the base 42. Preferably, the base 42
includes a horizontal portion 46 (which extends in the same direction as the length
direction of the first rail 26), an inclined portion 48 inclined at an angle with
respect to the horizontal portion 46, and a blocking wall 49 located on the other
side of the base 42 (i.e., on a different side from the horizontal portion 46). Preferably,
the pushing member 44 includes at least one contact portion, a to-be-blocked portion
51 to be blocked by the blocking wall 49 of the base 42, and an arm portion 53 elastically
connected to the pushing member 44. In this embodiment, the at least one contact portion
includes a first contact portion 50a and a second contact portion 50b by way of example.
[0020] Referring to FIG. 6A and FIG. 6B, when the pushing member 44 is at a horizontal position
(first position) P1 with respect to the base 42, both the first contact portion 50a
and the second contact portion 50b of the pushing member 44 are in contact with and
lie on the horizontal portion 46 of the base 42. Once the pushing member 44 is displaced
from the horizontal position P1 to an inclined position (second position) P2 with
respect to the base 42, the first contact portion 50a of the pushing member 44 is
in contact with and lies on the horizontal portion 46 of the base 42 while the second
contact portion 50b of the pushing member 44 is in contact with and lies on the inclined
portion 48 of the base 42; as a result, the pushing member 44 is tilted with respect
to the base 42 by an angle θ. When the pushing member 44 is at the inclined position
P2, the to-be-blocked portion 51 of the pushing member 44 is blocked by the blocking
wall 49 of the base 42 such that the pushing member 44 is kept at the inclined position
P2.
[0021] FIG. 7A to FIG. 7C show the pushing member 44 at the inclined position P2 with respect
to the base 42. FIG. 7A to FIG. 7C also show a normal state in which, while the second
rail 30 is longitudinally displaced relative to the first rail 26 in a first direction
D1 from a retracted position toward an extended position (please note that, in FIG.
7A∼FIG. 7C, the displacement and position of the second rail 30 relative to the first
rail 26 are represented by those of the actuator 40), the running carriage 36 is moved
together with the second rail (the actuator 40) in the intended (or normal) differential
manner with respect to the second rail (the actuator 40). That is to say, when the
second rail (the actuator 40) is displaced in the first direction D1 by a certain
distance, the running carriage 36 is synchronously and precisely moved by a distance
which is a specific proportion (e.g., one half) of the distance by which the second
rail (the actuator 40) is displaced. It should be pointed out that, when the pushing
member 44 is at the inclined position P2, the actuator 40 does not correspond to any
portion (e.g., the arm portion 53) of the pushing member 44 and therefore is unable
to drive the pushing member 44 while the second rail is displaced relative to the
first rail 26 from the retracted position toward the extended position.
[0022] FIG. 8A to FIG. 8C also show the pushing member 44 at the inclined position P2 with
respect to the base 42. In addition, FIG. 8A to FIG. 8C show a normal state in which,
while the second rail 30 is longitudinally displaced relative to the first rail 26
in a second direction D2 from the extended position toward the retracted position
(please note that, in FIG. 8A∼FIG. 8C, the displacement and position of the second
rail 30 relative to the first rail 26 are represented by those of the actuator 40),
the running carriage 36 is differentially moved relative to the second rail (the actuator
40) in the intended (or normal) manner.
[0023] However, after the second rail (the actuator 40) is repeatedly displaced back and
forth relative to the first rail 26 in the first direction D1 and the second direction
D2, it is no longer guaranteed that the distance by which the running carriage 36
is differentially moved will be precisely the preset proportion of the distance by
which the second rail (the actuator 40) is displaced, the reason being the difference
in rolling/sliding speed between the roller and the rails or some external factors.
As a result, an abnormal condition arises when the running carriage 36 is differentially
moved relative to the second rail (the actuator 40).
[0024] In FIG. 9A to FIG. 9D, wherein the pushing member 44 is initially at the inclined
position P2 with respect to the base 42, an abnormal state is shown in which, due
to an error in differential movement of the running carriage 36 relative to the second
rail (the actuator 40), there is also an error in the position of the running carriage
36 while the running carriage 36 is differentially moved relative to the second rail
(the actuator 40). In other words, the distance by which the running carriage 36 is
differentially moved relative to the second rail (the actuator 40) is not the preset
proportion of the distance by which the second rail (the actuator 40) is displaced.
In the presence of such errors, the running carriage 36 contacts the pushing member
44 (see FIG. 9C) while the second rail (the actuator 40) is retracted from the extended
position in the second direction D2. If the second rail (the actuator 40) is further
displaced relative to the first rail 26 in the second direction D2 toward the retracted
position, the pushing member 44 will be driven by the running carriage 36 such that
the second contact portion 50b of the pushing member 44 moves from the inclined portion
48 of the base 42 to the horizontal portion 46 of the base 42; in consequence, the
pushing member 44 is displaced relative to the base 42 from the inclined position
P2 to the horizontal position P1 (see FIG. 9D).
[0025] A detailed description of how to correct the aforesaid abnormal condition is given
below with reference to FIG. 10A to FIG. 10C, in which the pushing member 44 is initially
at the horizontal position P1 with respect to the base 42, and in which the actuator
40 corresponds to the arm portion 53 of the pushing member 44 at the horizontal position
P1. To correct the abnormal condition, the second rail (the actuator 40) is displaced
relative to the first rail 26 in the first direction D1 from the retracted position
toward the extended position so that, during the displacement, the actuator 40 pushes
the arm portion 53 due to the corresponding relationship between the actuator 40 and
the pushing member 44. The arm portion 53, in turn, drives the pushing member 44 from
the horizontal position P1 with respect to the base 42 to the inclined position P2,
in order for the pushing member 44 to displace the running carriage 36 to a predetermined
position (see FIG. 10B) where the running carriage 36 can be differentially moved
relative to the second rail (the actuator 40) in a normal manner. Thus, the error
in differential movement of the running carriage 36 relative to the second rail (the
actuator 40) is corrected. If the second rail (the actuator 40) is further displaced
relative to the first rail 26 in the first direction D1, the actuator 40 will release
the pushing member 44 having been driven to the inclined position P2; in consequence,
the actuator 40 no longer corresponds to the arm portion 53 of the pushing member
44 and can drive the pushing member 44 no more, thus allowing the running carriage
36 to be differentially moved relative to the second rail (the actuator 40) in a normal
manner again.
[0026] Reference is now made to FIG. 11A to FIG. 11D. Once capable of normal differential
movement, the running carriage 36 can be moved relative to the second rail 30 (the
actuator 40) in the intended differential manner as the second rail 30 is displaced
relative to the first rail 26 in the first direction D1 from the retracted position
(please note that, in FIG. 11A∼FIG. 11D, the displacement and position of the second
rail 30 relative to the first rail 26 are represented by those of the actuator 40).
Should the pushing member 44 be at the horizontal position P1 with respect to the
base 42, the actuator 40 will drive the pushing member 44 from the horizontal position
P1 to the inclined position P2 during displacement. Now that the running carriage
36 has been synchronously and differentially moved along with the second rail (the
actuator 40) in a normal manner by a certain distance in the first direction D1, the
pushing member 44 at the inclined position P2 is unable to drive the running carriage
36 (i.e., the pushing member 44 will not correct differential movement of the running
carriage 36).
[0027] In FIG. 12A to FIG. 12C, the pushing member 44 is at the horizontal position P1 with
respect to the base 42 due to external factors or by accident. In such a case, the
second rail 30 can be displaced relative to the first rail 26 in the second direction
D2 from the extended position (please note that, in FIG. 12A∼FIG. 12C, the displacement
and position of the second rail 30 relative to the first rail 26 are represented by
those of the actuator 40) in order for the actuator 40 to push and thereby elastically
bend the arm portion 53 of the pushing member 44 (see FIG. 12B) during the displacement.
Once moved past the arm portion 53 (see FIG. 12C), the actuator 40 corresponds to
the arm portion 53 of the pushing member 44 again.
[0028] FIG. 13A to FIG. 13C show the correction mechanism 300 in another embodiment of the
present invention. The correction mechanism 300 is different from its counterpart
in the previous embodiment substantially in that the first rail 26 is directly formed
with a horizontal portion 302 and an inclined portion 304.
[0029] While the pushing member 306 is displaced, at least one contact portion of the pushing
member 306 (e.g., the first contact portion 308 or the second contact portion 310)
is in contact with one of the horizontal portion 302 and the inclined portion 304.
Should an error occur in differential movement of the running carriage 312, the second
rail (the actuator 314) can be displaced in the first direction D1 from the retracted
position toward the extended position in order for the actuator 314 to drive the pushing
member 306 from the horizontal position P1 to the inclined position P2, and for the
pushing member 306 at the inclined position P2 to displace, and thereby correct the
differential movement error of, the running carriage 312. The actuator 314 releases
the pushing member 306 once the pushing member 306 is at the inclined position P2.
