Structure slide track assembly
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.
1) Field of the Invention
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.
2) Description of the Prior Art
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
As a result, the inventor herein developed the present invention which submitted in application for patent rights, wherein:
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.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to
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
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.
Claims
1. An improved structure slide track assembly comprised of an inner track that provides for installation on both the left and right sides of an active, pullout-type drawer, the said 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 said 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 said guide sleeve as well as a press section and a pawl projecting from the said spring; and a ball bearing channel rail at the side of the said guide sleeve in the said center track having a reticulated catch slot at its anterior-most extremity adjacent to the said guide sleeve spring; therefore, the said ball bearing channel rail catch slot is engaged and fixed by the said pawl of the said center track guide sleeve into a unitary structural entity; when the drawer is installed onto the said outer tracks, since the said ball bearing channel rails and the said center tracks are engaged into unitary structural entities, insertion from the said center tracks into the said ball bearing channel rails is quite smooth, while the said check element stepped crowns at the said inner tracks on the drawer force down the said press sections on the said guide sleeves to disengage the said ball bearing channel rails from the said center tracks and enable easy sliding by the drawer, thereby achieving efficient installation and the protection of the said ball bearing channel rails to prevent damage due to inappropriate installation.
