Despite the economic downturn caused by the COVID-19 pandemic, the company is showing excellent performance based on high-quality products, reasonable prices, and thorough production management.
The company’s recent registered patent for its ‘Vibration-Proof Door Stopper System’ has drawn much attention from the industry. The double design of the pedal rubber and the plate rubber absorbs shock when the one-touch horseshoe is released and prevents wearing of the direct connection piece due to vibration, thereby preventing malfunction.
The vibration proof door stopper system, which is the core design system of the ‘one-touch horseshoe’ produced by Cheong Gu Metal. It is designed based on the principle of an elastic piece (rubber pad) being located between the product base and the door, thereby absorbing shock and vibration caused by the folding operation of the lug (horseshoe plate).
This prevents loosening of fixtures such as the direct connection piece and damage to the door due to repeated vibration. Also, the elastic piece is firmly fitted into the intaglio groove of the base through the positioning block, so movement of the elastic piece is prevented during installation of the base, guaranteeing precision of installation even by an unskilled worker.
An official at Cheong Gu Metal explained, “In general, the door of a building such as a house is equipped with a door stopper to keep the door open, and the user keeps the door open by unfolding the lug of the door stopper and having it push against the floor. When closing the door, however, there was the cumbersome problem of having to lift the lug back to its original position.”
