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.

1 . A portable key assembly, the portable key assembly comprising a primary key body, a primary key-borne lock fastener, and a primary, two-sided, abbreviated key handle, the primary key-borne lock fastener being set on the primary key handle at one end of the primary key body.  
   
   
       2 . The portable key assembly of  claim 1  pivotally fastenable to select key-attachment structure, the select key-attachment structure for providing a torque arm relative to the key body for increasing torque for locking/unlocking key movement.  
   
   
       3 . The portable key assembly of  claim 2  wherein the select key-attachment structure is defined by at least one second portable key assembly, the second key assembly being substantially identical to the portable key assembly and matable thereto via the key-borne lock fasteners.  
   
   
       4 . The portable key assembly of  claim 2  wherein the select key-attachment structure is defined by a select key accessory, the select key accessory being outfitted with an accessory-borne lock fastener, the accessory-borne lock fastener being matable with the key-borne lock fastener for attaching the key assembly to the select key accessory.  
   
   
       5 . The portable key assembly of  claim 7  wherein the select key accessory is selected from the group consisting of a key card, a key strap, a key clip, and a key case.  
   
   
       6 . The portable key assembly of  claim 1  wherein the key-borne lock fastener is an elastic snap fastener.  
   
   
       7 . The portable key assembly of  claim 6  wherein the elastic snap fastener comprises two fastener ends, the fastener ends being exposed on opposite sides of the key handle  
   
   
       8 . The portable key assembly of  claim 8  wherein the two fastener ends are defined by a male fastener and a female fastener.  
   
   
       9 . The portable key assembly of  claim 1  wherein the lock fastener is a magnetic member attached to the key handle.  
   
   
       10 . The portable key assembly of  claim 1  wherein the key handle comprises a handle width and the key body has a body width, the handle width being substantially equal in magnitude to the body width.  
   
   
       11 . A portable key assembly, the portable key assembly comprising a key body, a key-borne lock fastener, and a two-sided key handle, the key-borne lock fastener being set on the key handle at one end of the key body.  
   
   
       12 . The portable key assembly of  claim 11  pivotally fastenable to select key-attachment structure, the select key-attachment structure for providing a moment arm relative to the key body for increasing torque for locking/unlocking key movement.  
   
   
       13 . The portable key assembly of  claim 12  wherein the select key-attachment structure is defined by at least one second portable key assembly, the second key assembly being substantially identical to the portable key assembly and matable thereto via the key-borne lock fasteners.  
   
   
       14 . The portable key assembly of  claim 12  wherein the select key-attachment structure is defined by a select key accessory, the select key accessory being outfitted with an accessory-borne lock fastener, the accessory-borne lock fastener being matable with the key-borne lock fastener for attaching the key assembly to the select key accessory.  
   
   
       15 . The portable key assembly of  claim 14  wherein the select key accessory is selected from the group consisting of a key card, a key strap, a key clip, and a key case.  
   
   
       16 . The portable key assembly of  claim 11  wherein the key-borne lock fastener is an elastic snap fastener.  
   
   
       17 . The portable key assembly of  claim 16  wherein the elastic snap fastener comprises two fastener ends, the fastener ends being exposed on opposite sides of the key handle  
   
   
       18 . The portable key assembly of  claim 17  wherein the two fastener ends are defined by a male fastener and a female fastener.  
   
   
       19 . The portable key assembly of  claim 1  wherein the lock fastener is a magnetic member attached to the key handle.  
   
   
       20 . The portable key assembly of  claim 1  wherein the key handle comprises a handle width and the key body has a body width, the handle width being substantially equal in magnitude to the body width.
