Abstract
A telescopic drawer slide including first, second and third drawer slides, each having a longitudinal length with a web and arcuate arms along the longitudinal margins of the web, the second drawer slide being nested within the arcuate arms of the first drawer slide, and the third drawer slide being nested within the arcuate arms of the second drawer slide. There is a lock between the second drawer slide and the first drawer slide, the lock having a biased tab rotatably coupled to the second drawer slide and an emboss on the first drawer slide. The tab moves into a portion of the emboss upon movement over the emboss, thereby preventing the second drawer slide from closing relative to the third drawer slide.
Claims14
A telescopic drawer slide comprising:
- a first drawer slide having a longitudinal length with a web and slideways along the longitudinal margins of the web;
- a second drawer slide having a longitudinal length with a web and slideways along the longitudinal margins of the web, the second drawer slide being nested within the slideways of the first drawer slide;
- a third drawer slide having a longitudinal length with a web and slider sections along the longitudinal margins of the web, the third drawer slide being nested within the slideways of the second drawer slide;
- and
- a lock between the second drawer slide and the first drawer slide, the lock comprising a tab rotatably coupled to the second drawer slide and an emboss on the first drawer slide;
- wherein the emboss comprises a ramp in the pathway of a first area of the tab and a catch, such that the ramp guides the tab over the emboss and the tab moves into locking engagement with the catch by the action of its own weight as the tab is moved past the emboss in an opening direction, and wherein a portion of the third slide is in the pathway of a second area of the tab and contacts the second area of the tab to move the tab out of engagement with the catch as the third slide is moved in a closing direction.
A telescopic drawer slide comprising:
- a first drawer slide having a longitudinal length with a web and slideways along the longitudinal margins of the web;
- a second drawer slide having a longitudinal length with a web and slideways along the longitudinal margins of the web, the second drawer slide being nested within the slideways of the first drawer slide;
- a third drawer slide having a longitudinal length with a web and slider sections along the longitudinal margins of the web, the third drawer slide being nested within the slideways of the second drawer slide;
- and
- a lock between the second drawer slide and the first drawer slide, the lock comprising a tab rotatably coupled to the second drawer slide and an emboss on the first drawer slide, wherein the tab is moveable from a neutral position to a locking position by the action of its own weight and wherein a movement of the second drawer slide in a closing direction causes the tab to lockingly engage the emboss, thereby preventing the second drawer slide from further movement in the closing direction, wherein a movement of the third slide member causes a contact with a second area of the tab to move the tab from the locking position to the neutral position.
