IMPROVED TRACK MEANS FOR DRAWERS
ABSTRACT
A track assembly for drawers includes a pair of spaced
stationary tracks securely mounted to longitudinal walls of
a piece of furniture which define a space for accommodating
a drawer and a pair of sliding members securely mounted to
outer longitudinal surfaces of the drawer which face the
stationary tracks. Each stationary track includes a strip
having an upper flange and a lower flange respectively
protruding from an upper edge and a lower edge thereof and
extending along a length thereof, thereby defining a sliding
track for the sliding member. The sliding members are
mounted to both outer longitudinal surfaces of the drawer
adjacent to a rear end thereof. A roller rotatably mounted
on each of the sliding members is received and rotatable in
the track, providing a smooth operation of the drawer. A
block is mounted to a front end of the stationary track and
has a smooth upper surface to support an underside of the
drawer, thereby providing a smooth supporting point for the
drawer during operation. A rear stop and a front stop are
respectively mounted to a rear end and a front end of the
stationary tracks for preventing the drawer from moving out
of the stationary tracks.

1 IMPROVED TRACK MEANS FOR DRAWERS
2 BACKGROUND OF TIIE INVENTION
3 The present invention relates to an improved track
4 means for drawers.
There are several well-known types of track means for
6 drawers. However, theses conventional track means have one
7 or more following disadvantages due to their structure: (1)
8 the drawer easily slides too far outward beyond the
9 compartment for the drawer when pulling out the drawer, (2)
assembly which is too involved, (3) difficult processing,
11 and (4) a high cost in manufacturing.
12 ~he present invention intends to provide an improved
13 track means to mitigate and/or obviate the above-mentioned
14 drawbacks.
SUMMARY OF THE INVENTION
16 A track means for drawers generally includes a pair of
17 spaced stationary tracks securely mounted to longitudinal
18 walls of a furniture, such as a desk, which define a space
19 for accommodating a drawer and a pair of sliding members
securely mounted to outer longitudinal surfaces of the
21 drawer which face the stationary tracks. According to one
22 aspect of the present invention, the track means is
23 characterized by that:
24 each stationary track includes a strip having an upper
flange and a lower flange respectively protruding from an
26 upper edge and a lower edge thereof and extending along a
27 length thereof, thereby defining a sliding track for the
28 sliding mem~er,

1 the sliding members are mounted to both outer
2 longitudinal surfaces of the drawer adjacent to a rear end
3 thereof, a roller rotatably mounted on each of the sliding
4 members is received and rotatable in the track, providing a
smooth operation of the drawer, a block is mounted to a
6 front end of the stationary track and has a smooth upper
7 surface to support an underside of the drawer, thereby
8 providing a smooth supporting point for the drawer during
9 operation, and
a rear stop is mounted to a rear end of the stationary
11 tracks for preventing the drawer from moving out of the
12 stationary tracks, a front stop is mounted to a front
13 portion of the stationary tracks for limiting a distance of
14 which the drawer is pulled out.
According to another aspect of the present inve~tion, a
16 contact strip is provided to a front end of the sliding
17 member so as to contact and to be stoppèd by the front stop
18 of the stationary track when pulling out the drawer.
19 According to still another aspect of the present
invention, the upper flange extends from a rear end of the
21 strip and terminates at a position before the front stop,
22 leaving a passage located in front of the upper flange to
23 allow the removal of the drawer by the contact strip and the
24 roller passing through the passage in front of the upper
flange.
26 According to yet another aspect of the present
27 invention, each rear end of the lower flange is slanted
28 downward to insure the drawer in its closed position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
21 Referring to Figs. 1 and 2, a track means for drawers
22 according to the present invention comprises a pair of
23 spaced stationary tracks 10 securely mounted to longitudinal
2~ walls of a furniture (such as a desk) which define a space
for accommodating a drawer 40 and a pair of sliding members
26 30 securely mounted to outer longitudinal surfaces 42 of the
27 drawer 40 which face the stationary tracks 10.
28 Each stationary track 10 includes a strip 19 having an
29

_ 5 _ 2073~6~
1 upper flange 16 and a lower flange 17 respectively
2 protruding from an upper edge and a lower edge thereof,
3 thereby defining a sliding track 15 for the sliding member
4 30. The lower flange 17 extends over a length of the strip
19. The upper flange 16 extends from a rear end of the strip
6 19 and terminates at a position before a front stop 14,
7 leaving a passage located in front of the upper flange 17,
8 whose purpose will be explained hereinafter.
9 The sliding members 30 are mounted to both outer
longitudinal surfaces of the drawer 40 adjacent to a rear
11 end thereof. A roller 31 rotatably mounted on each of the
12 sliding members 30 is received and rotatable in the track
13 15, providing a smooth operation of the drawer 40. A block
14 20 is mounted to a front end of the stationary track 10 and
has a smooth upper surface 20a to support an underside of
16 the drawer 40, thereby providing a smooth supporting point
17 for the drawer 40 during operation.
18 A rear stop 13 is mounted to a rear end of the
19 stationary tracks 10 for preventing the drawer 40 from
moving out of the stationary tracks 10. The front stop 14 is
21 mounted to a front portion of the stationary tracks 10 for
22 limiting a distance of which the drawer 40 is pulled out.
23 This is achieved by a contact strip 32 provided on a front
24 end of the sliding member 30 so as to contact and to be
stopped by the front stop 13 of the stationary track 10 when
26 pulling out the drawer 40.
27 When the user wishes to completely remove the drawer 40
28 from the desk, he may first pull out the drawer until the
29
,

1 roller moves to a position shown in the phantom lines in
2 Fig. 3, and then lift the drawer upward as clearly shown in
3 Fig. 3 to allow the removal of the drawer 40 by the contact
4 strip 32 and the roller 31 passing through the passage in
front of the upper flange 17.
6 As shown in Fig. 2, the rear ends of the stationary
7 tracks 10 are slanted downward to insure the drawer 40 in
8 its closed position. Furthermore, a mounting standard tab 11
9 extends downward from a rear end of the stationary track 10,
providing a mounting standard for mounting the stationary
11 track to the walls of the desk. For example, the person
12 installing the drawer may draw a horizontal line on the wall
13 and then mount the tracX on the wall with a lowest point of
14 the front end thereof located on the line and the lowest
point of the strip 11. By this way, the track slants
16 downward from the front end thereof to the rear end thereof,
17 preventing the drawer from unintentionally sliding out from
18 its closed position.
19 Referring to Fig. 4, for a wooden drawer, a claw 33 and
a screw 34 can be used to further secure the sliding members
21 30 to both side walls 41 and 42 of the wooden drawer 40.
22 Although the invention has been explained in relation
23 to its preferred embodiment, it is to be understood that
24 many other possible modifications and variations can be made
without departing the spirit and scope of the invention as
26 hereinafter claimed.
