Retractable bayonet

Abstract

A retractable bayonet that can be removably coupled to a firearm or used alone. The retractable bayonet includes a housing having a first side, a second side, an internal channel, a slot having first and second ends, and first and second opening; a blade configured to be displaced between a retracted position and an extended position along the internal channel within the housing; and a fastener secured to the blade and configured to slidingly engage with the slot. When the blade is in the retracted position, the fastener is positioned at the first end of the slot and engaged with the first opening. When the blade is in the extended position, the fastener is positioned at the second end of the slot and engaged with the second opening. With one-handed operations, the bayonet can be extended or retracted when not in use.

What is claimed is: 
     
         1 . A retractable bayonet, comprising:
 a housing comprising a first side and a second side, opposite the first side, and an internal channel extending between the first and second sides;   a slot arranged within the first side of the housing, the slot having first and second ends;   first and second openings arranged within the second side of the housing;   a blade positioned within the housing and configured to be displaced between a retracted position and an extended position along the internal channel within the housing; and   a fastener secured to the blade and configured to slidingly engage with the slot;   wherein when the blade is in the retracted position, the fastener is positioned at the first end of the slot and engaged with the first opening, and when the blade is in the extended position, the fastener is positioned at the second end of the slot and engaged with the second opening.   
     
     
         2 . The retractable bayonet of  claim 1 , wherein the housing is configured to be removably secured to a firearm. 
     
     
         3 . The retractable bayonet of  claim 1 , wherein the first side is parallel to a mark side of the blade. 
     
     
         4 . The retractable bayonet of  claim 1 , wherein the second side is parallel to a pile side of the blade. 
     
     
         5 . The retractable bayonet of  claim 1 , wherein the first and second sides of the housing are arranged in parallel to each other. 
     
     
         6 . The retractable bayonet of  claim 1 , wherein the slot is defined by continuous straight edges that extend between the first and second ends. 
     
     
         7 . The retractable bayonet of  claim 1 , wherein the first opening is arranged in parallel with the first end of the slot and the second opening is arranged in parallel with the second end of the slot. 
     
     
         8 . The retractable bayonet of  claim 1 , wherein the fastener is configured to extend outwardly through the slot. 
     
     
         9 . The retractable bayonet of  claim 1 , wherein the fastener is spring-loaded. 
     
     
         10 . The retractable bayonet of  claim 1 , wherein the fastener comprises a knob. 
     
     
         11 . The retractable bayonet of  claim 1 , wherein the fastener is configured to rotate to lock when in the retracted position or the extended position. 
     
     
         12 . The retractable bayonet of  claim 1 , wherein the internal channel extends longitudinally along an inside surface the housing. 
     
     
         13 . A system comprising a removable retractable bayonet, comprising:
 a firearm having a mounting platform; and   a retractable bayonet removably securable to the mounting platform of the firearm, the retractable bayonet comprising:
 a housing comprising a longitudinal top side and first and second lateral sides extending from the longitudinal top side, the longitudinal top side and the first and second lateral sides at least partially defining an internal cavity; 
 an extension configured to engage the mounting platform of the firearm, the extension comprising a plurality of channels, and the extension extending from the first lateral side; 
 a recess arranged longitudinally within the second lateral side of the housing; 
 an internal channel extending along an inside surface of the longitudinal top side and within the internal cavity of the housing; 
 a blade configured to be displaced within the internal channel; and 
 a cross-bolt assembly configured to engage the recess and the plurality of channels of the extension to removably secure the retractable bayonet to the firearm. 
   
     
     
         14 . The system of  claim 13 , wherein the plurality of channels are substantially perpendicular to the recess within the second lateral side of the housing. 
     
     
         15 . The system of  claim 13 , wherein the retractable bayonet further comprises:
 a slot arranged within the first lateral side of the housing, the slot having first and second ends;   first and second openings arranged within the second lateral side of the housing; and   a fastener secured to the blade and configured to slidingly engage with the slot;   wherein when the blade is in a first position, the fastener is positioned at the first end of the slot and engaged with the first opening, and when the blade is in a second position, the fastener is positioned at the second end of the slot and engaged with the second opening.   
     
     
         16 . The system of  claim 15 , wherein the fastener is configured to extend outwardly through the slot. 
     
     
         17 . The system of  claim 15 , wherein the fastener is spring-loaded and configured to rotate to lock when in the first position or the second position. 
     
     
         18 . The system of  claim 15 , wherein the first opening is arranged in parallel with the first end of the slot and the second opening is arranged in parallel with the second end of the slot. 
     
     
         19 . The system of  claim 15 , wherein the fastener is spring-loaded. 
     
     
         20 . The system of  claim 15 , wherein the fastener is configured to rotate to lock when in the retracted position or the extended position.
