Portable key assembly

Abstract

A portable key assembly occupies less space and is attachable to certain attachment structures for providing a key-turning moment arm. The portable key assembly is set with a key body, a lock fastener, and an abbreviated key handle on one end of the key body. The portable key assembly can be connected and overlapped in face-to-face relation with other keys or key accessories so that the same may be well combined, easily located, and convenient to carry. A moment arm extension can be formed by connecting the portable key assembly with other keys or key accessories. The turning torque of the key handle may thus be enlarged so that the portable key assembly can function properly even if the key handle is shortened and the volume of the whole key is reduced.

Description

PRIOR HISTORY [0001] This application is a non-provisional patent application claiming priority to Chinese Patent Application No. 200520112382.3, filed in the Chinese Patent Office on Jun. 8, 2005. FIELD OF THE INVENTION [0002] The present invention generally relates to an apparatus used to open a lock. More particularly, the present invention relates to a portable key and method of its use. DESCRIPTION OF PRIOR ART [0003] A key is a frequently used article in daily life. Generally, a key comprises a key body and a key handle. The key body is used to lock and unlock a lock. The width of the key handle is typically greater in magnitude than the width of the key body. Thus, the key handle functions, in part, to increase the turning torque of the key body during unlocking movement. The key handle may further function to provide certain convenient carrying means as may be taught or defined by certain key accessories such as a key ring, a key chain, or a key case as connected or coupled ...

AI Technical Summary

Benefits of technology

[0005] It is thus an object of the present invention to overcome the above-mentioned shortcomings, in part, by reducing the volume of a single key and thus enabling compact key bunch storage and transport. For example, when the key is connected with or coupled to other key accessories, the resulting assemblage may provide a convenient-to-carry and easy-to-use set of keys.

[0008] A further usage may be defined by methodology after connecting the key with other keys or key accessories. In this regard, it is contemplated that the post-connect methodology may be defined by turning the key utilizing the connected keys and or key accessories as torque arms, thereby enhancing or easing unlocking movement of the key.

Problems solved by technology

A disadvantage of the enlarged key handle is that the enlarged key handle simultaneously expands the volume of the key thereby occupying a relatively larger space and often results in a key bunch that is out of order, and / or inconvenient to carry after connecting with other key accessories.
