Box for receiving an electrostatic fabric

Abstract

A box for receiving an electrostatic fabric includes a top cover, a sliding member and a bottom cover. The sliding member is received and slidable in the box, and has a fixing portion mounting with an electrostatic fabric and a tongue having a through opening adjacent to the fixing portion. Two resilient arms extend from the fixing portion toward the through opening of the tongue, and two sliding blocks are provided at free ends of the two resilient arms, in which the two sliding blocks cooperate with two stoppers of the top cover to selectively control the sliding member at a lock state and a release state. When the sliding member is located at a lock state, the electrostatic fabric extends outside the box through a first opening of the box, but when the sliding member is located at a release state, the electrostatic fabric retracts in the box.

1 . A box for receiving an electrostatic fabric, comprising: 
 a top cover having a hole, two guides, two stoppers, a plurality of positioning pins, and a third notch and a fourth notch;    a sliding member having a fixing portion mounting with an electrostatic fabric, a tongue having a through opening adjacent to the fixing portion, two sliders extending from a top surface of the tongue, which are received and slidable in the two guides of the top cover, two resilient arms extending from the fixing portion toward the through opening of the tongue and having two sliding blocks provided at free ends thereof, in which the two sliding blocks and the two stoppers of the top cover cooperate with each other to selectively control the sliding member at a lock state and a release state, two hooks provided at each side of the tongue;    a bottom cover having a guiding post corresponding to the hole of the top cover, a plurality of positioning holes corresponding to the plurality of positioning pins, and a third notch and a fourth notch;    a button having a flange and coupled to an end of a helical spring sleeved on the guiding post of the bottom cover, in which the button is biased by the helical spring against the hole of the top cover and the flange is between the hole of the top cover and the two resilient arms of the sliding member, two springs connecting the two hooks and two fixing post of the bottom cover, whereby when the top cover and the bottom cover are assembled, the first notch and the third notch forms a first opening at one end of the box, and the second notch and the fourth notch forms a second opening at the other end thereof, so that the electrostatic fabric can selectively extend outside the box through the first opening, while the tongue of the sliding member selectively retracts in the box through the second opening thereof.    
   
   
       2 . The box as claimed in  claim 1 , wherein the two sliding blocks each have an inclined plane and a vertical plane, and the two stoppers each have an inclined plane and a vertical plane corresponding to the inclined plane and the vertical plane of the two sliding blocks, respectively.  
   
   
       3 . The box as claimed in  claim 1 , wherein top surfaces of the two resilient arms at free ends thereof are located above the tongue of the sliding member.  
   
   
       4 . The box as claimed in  claim 1 , wherein the flange of the button has a diameter larger than a distance between the two resilient arms and a diameter of the hole of the top cover.  
   
   
       5 . The box as claimed in  claim 1 , wherein the two sliders each have an inclined plane for easily sliding in each guide of the top cover.  
   
   
       6 . The box as claimed in  claim 1 , wherein two of the plurality of positioning holes are formed on the two fixing posts, respectively.  
   
   
       7 . The box as claimed in  claim 1 , wherein the top cover further has two ribs projecting from an inner surface thereof and abutting against a top surface of the fixing portion of the sliding member, and the bottom cover further has two ribs projecting from an inner surface thereof and abutting against a bottom surface of the fixing portion of the sliding member.
