System and device for stiffening a door

Abstract

Presented herein is a system for stiffening and strengthening a door, said system comprising a plurality of stoppers each having a channel, wherein said stoppers are affixed to the door; and at least one stiffening rod seated within the channels of said stoppers; and means for shortening the span of said stiffening rod disposed between said stoppers; whereby shortening the span results in straightening the door.

Description

Technical field [0001] The present invention relates generally to sliding doors, and in particular to components for such doors. Background technique [0002] Many cabinets, closets and other passages are equipped with sliding doors. Although sliding doors are easy to install and operate and do not require hinges or even door handles, these doors tend to twist over time, such as bending (in which the wood is bent against the grain), and warping or twisting. It is known in the prior art to attach certain wooden reinforcements to wood panels to help prevent bending. As long as the reinforcement itself is not distorted, this can prove to be an effective way to strengthen the sliding door. However, when heavy objects such as mirrors are hung on the sliding door, simple wooden reinforcements may not be enough to prevent the door from twisting. [0003] WO9743098 provides another solution, which is quoted in its entirety below, which teaches inserting reinforcements into holes drilled...

This can help prevent cupping (where the lateral sides of the lumber boards bend towards each other), but may not be effective against twisting and does not resolve the bowing at all
