Abstract

A front installing drawer pulling force adjusting apparatus is installed at a front end of a slide. The slide includes a bottom rail, a middle rail and an internal rail. The bottom rail has a latch element at the front end. The bottom rail has a slidable middle rail. The internal rail is embedded onto the middle rail and slid on the middle rail. The front end of the internal rail includes a limit element having a resilient element corresponding to the latch element. The internal rail is connected to an object that needs to be moved. During assembling, a portion intersecting the resilient element in the limit element with the limit element determines the level of retraction of the resilient element to adjust the tightness of clamping the resilient element onto the latch element of the bottom rail, so that users can open a drawer with an appropriate force.

Dependent claims

A front installing drawer pulling force adjusting apparatus, comprising:

a bottom rail, fixed on an object, and having a latch element protruded from an end of said bottom rail;
a middle rail, embedded onto said bottom rail, and moved back and forth on said the bottom rail;
an internal rail, embedded onto said middle rail, and moved back and forth on said middle rail, and coupled with said object that needs to be moved;
a limit element, embedded and movably sliding on said internal rail, and having a containing space;
and
a resilient element, fixed onto said internal rail, and contained in said containing space of said limit element, and both sides of said resilient element separately having a swingable wing bracket;
thereby, said limit element is moved to a predetermined position on said internal rail to adjust the position intersected with said resilient element during an installation, determine the level of tightness of clamping said resilient element onto an embedding slot of said latch element, and allow a user to appropriately adjust said positioning base as required, so as to open a drawer within a range of appropriate applying forces.
