Title: Ho Ping Cheng: Innovator in Ring Binder Mechanisms
Introduction
Ho Ping Cheng is a notable inventor based in Hong Kong, China. He has made significant contributions to the field of stationery products, particularly in the design and functionality of ring binder mechanisms. With a total of 12 patents to his name, Cheng has demonstrated a commitment to innovation and practicality in his inventions.
Latest Patents
Cheng's latest patents include a sophisticated ring binder mechanism that features a housing with a central portion and lateral sides. This design incorporates hinge plates held between the lateral sides of the housing. Each of the multiple rings includes at least one ring member that is mounted for movement with the hinge plates between closed and open positions. An actuator is pivotal relative to the housing and engages with the hinge plates to facilitate the opening of the rings. In one embodiment, the housing defines a stop that engages the actuator when it reaches a terminal position, effectively limiting the pivoting movement of the actuator in the opening direction. Another embodiment focuses on enhancing the response time of the binder when the actuator is moved to open the rings.
Additionally, Cheng has developed a soft close ring binder mechanism that securely retains loose-leaf pages. This mechanism features a housing that supports two hinge plates, allowing for the pivoting motion necessary to open and close paired ring members. The free ends of these ring members have interlocking configurations that prevent the inadvertent loss of pages. The mechanism also includes locking elements that interact with the hinge plates to block their pivoting motion when the ring members are closed, ensuring that the interlocking configurations remain engaged.
