Drawer guide rail assembly

Abstract

A guide rail assembly comprises a mounting bracket having a fixed rail on the mounting bracket for receiving an intermediate rail capable of sliding back and forth relative to the fixed rail, an outer pull out guide for attachment to the drawer and being capable of sliding back and forth on the intermediate rail relative to the intermediate rail and the fixed rail, a protrusion on the bottom surface of the outer pull out guide, a damping device and a channel guide disposed along the mounting bracket adjacent the fixed rail. The damping device is resiliently compressible in a lengthwise direction and the channel guide is provided with a sliding member. The sliding member includes an inner portion that travels within the guide and an outer portion that extends outwardly from the guide so as to be contactable by the pull out guide protrusion. The inner portion of the sliding member locates an end of the damping device that can be pushed inwardly to provide damping. During a closing action of the assembly, the outer pull out guide is caused to slide in a drawer-closing direction and when the protrusion reaches and contacts the sliding member outer portion, the sliding member travels within the channel guide against the resilience of the damping device and causes deceleration of the drawer-closing motion.

Description

technical field [0001] The present invention relates to a guide rail assembly for use in the furniture industry, and more particularly to a guide rail assembly for use in slidingly opening and closing drawers. [0002] Drawer guide rails are parts that are used every day, e.g. for drawers in desks or cabinets, for example in pull-out shelves in warehouses, cash registers in supermarkets, automatic information machines in bank kiosks, telephone switching stations electronic equipment, etc. Background technique [0003] Guide rails are provided for drawers that can be partially or fully opened or closed, and typically consist of brackets that secure the assembly to the furniture piece, fixed rails mounted on the brackets, pull-out rails attached and the middle track between the pull-out track. The middle rail slides on the fixed rail and the pull-out rail slides on the middle rail due to the sliding roller frame arranged between the fixed and pull-out rails. The running dis...

Problems solved by technology

This can cause inconsistencies in the movement of the rod into the cylinder along the same axis, cause insufficient compression of the linear dampers, and result in ineffective dampening or slowing down of the drawer closing force

[0009] In addition, the use of prior art systems is limited by the fact that the mounting plate of the linear damper fits into a recess on the horizontal ridge of the cabinet mounting track, due to the inability to adjust when the length of the track element changes

In other words, because the position of the linear buffer mounting plate on the cabinet mounting track cannot be flexibly adjusted, the existing technology lacks flexibility
