Structure slide track assembly
Abstract
An improved structure slide track assembly comprised of an inner
track, it having a check element on its exterior surface and a
solid, stepped crown extending from the top of the check element
and an outer track that contains a ball bearing channel rail and a
center track. The ball bearing channel rail has a reticulated catch
slot that is engaged by a spring-based pawl of the center track
guide sleeve into a unitary structural entity. When the drawer is
installed onto the outer tracks, while the check element stepped
crowns at the drawer inner tracks force down press sections on the
guide sleeves to disengage the ball bearing channel rails from the
center tracks and enable easy sliding with the drawer. As such, the
present invention achieves efficient installation and the
protection of the ball bearing channel rails to prevent damage due
to inappropriate installation.

Description
BACKGROUND OF THE INVENTION
[0001] 1) Field of the Invention
[0002] The invention herein relates to an improved structure slide
track assembly that provides for the efficient installation of desk
or cabinet drawers onto outer tracks containing a center track and
a ball bearing channel rail as well as the protection of the ball
bearing channel rails to prevent damage due to inappropriate
installation.
[0003] 2) Description of the Prior Art
[0004] The pull-out type keyboard trays and drawers respectively
utilized in computer desks and cabinets are typically comprised of
an inner track A installed onto the two sides of a said tray or
drawer and an outer track B along two sides for mounting the tray
or drawer, the said outer track B containing a ball bearing channel
rail C and a center track D (as shown in FIG. 1-A, -B.), with the
ball bearing channel rail C situated in the center track D fully
capable of sliding freely; as such, when the drawer is installed
onto the outer tracks B, the aligned insertion affords interactive
movement with the ball bearing channel rail C and the center track
D; however, when the inner tracks A at the two sides of the drawer
are installed onto the center tracks D and the ball bearing channel
rails C in the outer tracks B, since the ball bearing channel rails
C are not at the anterior-most extremity of the center tracks D,
after the entry of the inner tracks A into the center tracks D, the
ball bearing channel rails C separate if the ball bearing channel
rails C are improperly aligned, at which time most users only
perceive a slight tightness and then proceed to shove forcefully,
which subjects the ball bearing channel rails C to an excessive
thrusting force that causes bending, damage, and even the
dislodging of the ball bearings C1 (as shown in FIG. 1-C).
SUMMARY OF THE INVENTION
[0005] As a result, the inventor herein developed the present
invention which submitted in application for patent rights,
wherein:
[0006] The primary objective of the invention herein is to provide
an improved structure slide track assembly comprised of an inner
track that is installed on both the left and right sides of an
movable, pullout-type drawer, the inner track having a check
element on its exterior surface, the said check element serving as
a means of separating the drawer and outer track, and a solid,
stepped crown extending from the top of the check element; an outer
track that contains a ball bearing channel rail and a center track;
a center track having a guide sleeve installed at its anterior-most
extremity, with a spring disposed on the guide sleeve as well as a
press section and a pawl projecting from the spring; and a ball
bearing channel rail at the side of the guide sleeve in the center
track having a reticulated catch slot at its anterior-most
extremity adjacent to the guide sleeve spring; therefore, the ball
bearing channel rail catch slot is engaged and fixed by the pawl of
the center track guide sleeve into a unitary structural entity;
when the drawer is installed onto the outer tracks, since the ball
bearing channel rails and the center tracks are engaged into a
unitary structural entities, insertion from the center tracks into
the ball bearing channel rails is quite smooth, while the check
element stepped crowns at the drawer inner tracks force down the
press sections on the guide sleeves to disengage the ball bearing
channel rails from the center tracks and enable easy sliding by the
drawer, thereby achieving efficient installation and the protection
of the ball bearing channel rail to prevent damage due to
inappropriate installation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] Referring to FIG. 2-A, FIG. 2-B, and FIG. 2-C, the improved
structure slide track assembly of the invention herein is comprised
of an inner track 1 that provides for installation on both the left
and right sides of a movable, pullout-type drawer, the inner track
1 having a check element 11 on its exterior surface, the said check
element 11 functioning as a means of separating the drawer and
outer track 2, and a solid, stepped crown 111 extending from the
top of the check element 11; an outer track 2 suitably positioned
at the inner track 1 inside the drawer that contains a ball bearing
channel rail 3 and a center track 4; a center track 4 having a
guide sleeve 41 installed at its anterior-most extremity, with a
spring 411 disposed on the guide sleeve 41 as well as a press
section 412 and a pawl 413 projecting from the spring 411; and a
ball bearing channel rail 3 at the side of the guide sleeve 41 in
the center track 4 having a reticulated catch slot 31 at its
anterior-most extremity adjacent to the guide sleeve 41 spring
411.
[0016] Therefore, after the ball bearing channel rail 3 and the
center track 4 are assembled to the outer track 2, the ball bearing
channel rail 3 is pushed towards the center track 4 such that the
ball bearing channel rail 3 catch slot 31 is engaged by the pawl
413 of the center track 4 guide sleeve 41, thereby forming a
unitary structural entity (as shown in FIG. 2-C); as a result, when
the drawer installed onto the outer tracks 2, since the ball
bearing channel rails 3 and the center tracks 4 are engaged into
unitary structural entities, the inner tracks 1 are smoothly
admitted from the center tracks 4 into the ball bearing channel
rails 3 (as shown in FIG. 3), following which the check element 11
stepped crowns 111 force down the press sections 412 on the guide
sleeves 41, thereby disengaging the ball bearing channel rails 3
from the center tracks 4 and causing contact with the inner tracks
1 to enable sliding operation (as shown in FIG. 4); conversely,
when the drawer and the outer tracks 2 are separated, pulling
outward causes the ball bearing channel rail 3 catch slots 31 to
become re-engaged and fixed into position by the pawls 413 of the
center track 4 guide sleeves 41 such that when the inner tracks I
are conjoined again, the operation is efficient and without the
occurrence of problems formerly encountered.
[0017] As a result, since the ball bearing channel rail 3 and the
center track 4 of the invention herein are first assembled into
unitary structural entity to serve as a means of guidance such that
the drawer installation is efficiently completed and, furthermore,
the ball bearing channel rail 3 is protected to prevent damage due
to inappropriate installation, the present invention is
demonstrably progressive and thus meets the new patent application
requirements stipulated by Article 93 of the Patent Law, and is
submitted to the Patent Bureau for review and the granting of the
commensurate patent rights.
