Handle-less key assembly

Abstract

A handle-less key assembly occupies less space and is attachable to certain attachment structures for providing a key-turning torque arm. The handle-less key assembly is set with a key body, a lock fastener, and an abbreviated key handle on one end of the key body. The handle-less 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 torque arm extension can be formed by connecting the handle-less key assembly with other keys or key accessories or to a key post. The turning torque of the key assembly thus be enlarged via the key post, key accessory, or successively connected key bodies so that the handle-less key assembly can function properly even if the key handle is shortened and the volume of the whole key is reduced.

1 . A handle-less first key assembly, the first key assembly comprising a handle-less key and a control-stick, the handle-less key having a key width and comprising a stick-receiving aperture at a first end thereof, the control-stick being joined to the handle-less key via the at the aperture such that the control stick is perpendicular to the handle-less key, the control stick functioning as a first torque arm for turning the key within a lock. 
   
   
       2 . The key assembly of  claim 1  wherein the handle-less key comprises a fastening annulus, the fastening annulus defining the stick-receiving aperture and being cooperative with the control stick for joining the control stick to the handle-less key, the annulus having an outer annular diameter equal in magnitude to the key width. 
   
   
       3 . The key assembly of  claim 1  wherein the control stick comprises a transverse stick diameter and the annular jack comprises an inner annular diameter, the transverse stick diameter being sized for snug receipt by the inner annular diameter at a stick to annulus junction, the junction minimizing gaps between the handle-less key and the control stick for reducing wear and tear of the first key assembly. 
   
   
       4 . The key assembly of  claim 3  wherein the control stick is connected to a second handle-less key, the second handle-less key being substantially identical to the first handle-less key. 
   
   
       5 . The key assembly of  claim 3  wherein the control stick is connected to a key accessory. 
   
   
       6 . The key assembly of  claim 4  wherein the second handle-less key is rotatable about the post axis for providing a second torque arm for turning the handle-less key within a lock. 
   
   
       7 . The key assembly of  claim 5  wherein the key accessory is rotatable about the post axis for providing a second torque arm for turning the handle-less key within a lock. 
   
   
       8 . The key assembly of  claim 6  wherein the second handle-less key and control stick are orthogonally orientable to one another and the first handle-less key for enhancing turning movement of the first handle-less key within a lock. 
   
   
       9 . The key assembly of  claim 7  wherein the key accessory and control stick are orthogonally orientable to one another and the first handle-less key for enhancing turning movement of the first handle-less key within a lock. 
   
   
       10 . A key assembly, the key assembly comprising a cylindrical post, a planar key body, and a fastener, the post having a post base and a fastener attachment end, the key body having a uniform width and an apertured end, the apertured end defining a post-receiving annulus, the fastener having a fastener base, and a post attachment end, the post being orthogonally insertable through the post-receiving annulus, the fastener attachment end being fastened to the post attachment end, the post base and fastener base preventing axial displacement of structure received therebetween relative to the post, the post providing a torque arm for turning the key body when inserted in a lock. 
   
   
       11 . The key assembly of  claim 10  comprising a successive key, the successive key being substantially identical to the key body, the key body having a body thickness, the post having a post length, the post length being greater in magnitude than the body thickness for receiving both the key body and the successive key. 
   
   
       12 . The key assembly of  claim 10  comprising a key accessory, the key accessory comprising an accessory annulus at one end thereof and an accessory thickness, the post comprising a post length, the post length being greater in magnitude than the body thickness and accessory thickness for receiving both the key body and the key accessory. 
   
   
       13 . The key assembly of  claim 11  wherein the second handle-less key is rotatable about the post axis for providing a second torque arm for turning the handle-less key within a lock. 
   
   
       14 . The key assembly of  claim 12  wherein the key accessory is rotatable about the post axis for providing a second torque arm for turning the handle-less key within a lock. 
   
   
       15 . The key assembly of  claim 13  wherein the second handle-less key and control stick are orthogonally orientable to one another and the first handle-less key for enhancing turning movement of the first handle-less key within a lock. 
   
   
       16 . The key assembly of  claim 14  wherein the key accessory and control stick are orthogonally orientable to one another and the first handle-less key for enhancing turning movement of the first handle-less key within a lock. 
   
   
       17 . A key assembly, the key assembly comprising a post, a key body, and a fastener, the post having a post base and a fastener attachment end, the key body having a uniform width and an apertured end, the apertured end defining a post-receiving annulus, the fastener having a fastener base, and a post attachment end, the post being orthogonally insertable through the post-receiving annulus, the fastener attachment end being fastened to the post attachment end, the post base and fastener base preventing axial displacement or structure received therebetween relative to the post, the post providing a torque arm for turning the key body when inserted in a lock. 
   
   
       18 . The key assembly of  claim 17  comprising a successive key, the successive key being substantially identical to the key body, the key body having a body thickness, the post having a post length, the post length being greater in magnitude than the body thickness for receiving both the key body and the successive key. 
   
   
       19 . The key assembly of  claim 17  comprising a key accessory, the key accessory comprising an accessory annulus at one end thereof and an accessory thickness, the post comprising a post length, the post length being greater in magnitude than the body thickness and accessory thickness for receiving both the key body and the key accessory.
