Activating device to open all the boxes of tool box

Abstract

A tool box includes a casing with at least one open side for a plurality of boxes pivotally received therein. A link is pivotally connected to the boxes and located at a distance from the pivotal point of the boxes. An activation member is pivotally connected to one of the boxes and has a slot for receiving a boss extending from the link so that when pivoting the activation member, the link pivots the boxes to open. A spring is connected between the activation member and the casing so as to close all the boxes by pulling the activation member.

         2 . The tool box as claimed in  claim 1 , wherein the tool box has a first flange extending from an bottom of a top and each of the boxes has a front plate and a back plate, the back plate of the top most box contacting the first flange when the top most box is in close position.  
     
     
         3 . A tool box comprising: 
 a casing having an open side and a plurality of boxes pivotally connected between a front wall and a back wall of the casing at a first position of each of the boxes, the boxes being able to be pivotally opened in the open side;    a link pivotally connected to each of the boxes at a second position on each of the boxes and a distance being defined between the first position and the second position, the link having a plurality of slots defined therethrough and each box having a boss extending from the second position, the bosses being movably received in the slots respectively, and    a spring having an end fixedly connected to the casing and the other end of the spring connected to the second position of one of the boxes.    
     
     
         4 . The tool box as claimed in  claim 3 , wherein the tool box has a first flange extending from an bottom of a top and each of the boxes has a front plate and a back plate, the back plate of the top most box contacting the first flange when the top most box is in close position.  
     
     
         5 . A tool box comprising: 
 a casing having two open sides and two rows of boxes pivotally connected between a front wall and a back wall of the casing at a first position of each of the boxes, the boxes being able to be pivotally opened in the two open sides;    two links respectively and pivotally connected to each of the two rows of boxes at a second position of each of the two rows of boxes and a distance being defined between the first position and the second position;    two plates respectively connected to the two boxes located at the top most position of the two rows of the boxes, each plate having a notch defined therein, and    an activation member having a disk which is rotatably connected to the casing, two lugs extending from the disk and one of the two lugs engaged with one of the two notches when rotating the activation member.    
     
     
         6 . The tool box as claimed in  claim 5 , wherein the tool box has a first flange extending from an bottom of a top and each of the boxes has a front plate and a back plate, the back plate of the top most box contacting the first flange when the top most box is in close position.  
     
     
         7 . A tool box comprising: 
 a casing having an open side and a plurality of boxes pivotally connected between a front wall and a back wall of the casing at a first position of each of the boxes, the boxes being able to be pivotally opened in the open side;    a link pivotally connected to each of the boxes at a second position on each of the boxes and a distance being defined between the first position and the second position, a boss extending from the link;    a shaft extending from one of the boxes and an activation member having an end movably mounted to the shaft, a slot defined in the activation member and the boss received in the slot, a spring being biased between the activation member and an inside of the casing, a slot defined through the casing and having a protrusion extending from one of two insides of the slot, the activation member being positioned by the protrusion.    
     
     
         8 . The tool box as claimed in  claim 7 , wherein the tool box has a first flange extending from an bottom of a top and each of the boxes has a front plate and a back plate, the back plate of the top most box contacting the first flange when the top most box is in close position.  
     
     
         9 . A tool box comprising: 
 a casing having an open side and a plurality of boxes pivotally connected between a front wall and a back wall of the casing at a first position of each of the boxes, a first gear co-axially connected to the first position of one of the boxes which are able to be pivotally opened in the open side;    a link pivotally connected at a second position of each of the boxes and a distance defined between the first position and the second position, and    an activation member pivotally connected to one of the boxes and a driving member (second gear) connected to the activation member, the driving member (second gear) engaged with the first gear.    
     
     
         10 . The tool box as claimed in  claim 9 , wherein the tool box has a first flange extending from an bottom of a top and each of the boxes has a front plate and a back plate, the back plate of the top most box contacting the first flange when the top most box is in close position.
