Telescopic tool support

Abstract

A telescopic tool support comprises a seat having a first top wall and two opposite first sidewalls, a top cover at least partially enclosing the seat and having a second top wall and two opposite second sidewalls, and an adjustable locking device adapted to couple the top cover to the seat, wherein the adjustable locking device has at least one locking tab, at least one engagement-actuating device, and at least one coupling device. The at least one coupling device couples or decouples the seat and the top cover by at least one locking tab preferably resiliently connected to the seat. The at least one engagement-actuating device is moveable between an unlocked position and a locked position, and is configured for, when it is at said locked position, enabling the coupling of said coupling device under the aid of said locking tab so as to have the top cover and the seat engaged at a desired coupling location; and for, when it is at said unlocked position, enabling the decoupling of said coupling device so as to allow the sliding of the top cover with respect to the seat. When the at least one engagement-actuating device is at the unlocked position, the tool support can be telescoped so as to adjust the accommodation size, and when the at least one engagement-actuating device is at a locked position, the top cover cannot move with respect to the seat such that the accommodation size of the tool support is maintained.

1 . A telescopic tool support, comprising: 
 a seat ( 10 );    a top cover ( 20 ) at least partially enclosing said seat and slidable with respect to said seat;    an adjustable locking device provided between said seat and said top cover, said adjustable locking device comprising at least one locking tab ( 13 ), at least one engagement-actuating device ( 30 ,  40 ,  50 ), and at least one coupling device which couples or decouples the seat and the top cover by said at least one locking tab ( 13 ) and said engagement-actuating device ( 30 ,  40 ,  50 ); said engagement-actuating device being moveable between an unlocked position and a locked position;    wherein:    said engagement-actuating device ( 30 ,  40 ,  50 ) is configured for, when it is at said locked position, enabling the coupling of said coupling device under the aid of said locking tab so as to have the top cover and the seat engaged at a desired coupling location; and for, when it is at said unlocked position, enabling the decoupling of said coupling device so as to allow the sliding of the top cover with respect to the seat.    
   
   
       2 . The telescopic tool support as claimed in  claim 1 , wherein said engagement-actuating device is at least one latching device ( 30 ) having a sleeve ( 31 ) and a latch ( 32 ), said latch being slidable along said sleeve between said unlocked position and said locked position so as to enable said decoupling or coupling of said coupling device.  
   
   
       3 . The telescopic tool support as claimed in  claim 1 , wherein said engagement-actuating device is at least one eccentric engagement-actuating member ( 40 ) having an ejecting rod ( 41 ) and an eccentric pivot ( 42 ) disposed on the ejecting rod, such that the ejecting rod can rotate between said unlocked position and said locked position around the eccentric pivot so as to enable said decoupling or coupling of said coupling device.  
   
   
       4 . The telescopic tool support as claimed in  claim 1 , wherein said engagement-actuating device is at least one supporting rod ( 50 ) disposed to contact a predetermined location of said at least locking tab ( 13 ), such that said supporting rod can move between said unlocked position and said locked position so as to enable said decoupling or coupling of said coupling device.  
   
   
       5 . The telescopic tool support as claimed in  claim 1 , wherein said at least one coupling device comprises a toothed structure ( 14 ) formed on said locking tab ( 13 ) and a corresponding rack ( 23 ) for being engaged with said toothed structure ( 14 ).  
   
   
       6 . The telescopic tool support as claimed in  claim 2 , wherein said at least one coupling device comprises a toothed structure ( 14 ) formed on said locking tab ( 13 ) and a corresponding rack ( 23 ) for being engaged with said toothed structure ( 14 ).  
   
   
       7 . The telescopic tool support as claimed in  claim 3 , wherein said at least one coupling device comprises a toothed structure ( 14 ) formed on said locking tab ( 13 ) and a corresponding rack ( 23 ) for being engaged with said toothed structure ( 14 ).  
   
   
       8 . The telescopic tool support as claimed in  claim 4 , wherein said at least one coupling device comprises a toothed structure ( 14 ) formed on said locking tab ( 13 ) and a corresponding rack ( 23 ) for being engaged with said toothed structure ( 14 ).  
   
   
       9 . The telescopic tool support as claimed  claim 1 , wherein said at least one locking tab ( 13 ) is resiliently connected to a first top wall (  1 ) of said seat ( 10 ).  
   
   
       10 . The telescopic tool support as claimed in  claim 9 , wherein an elastomer is disposed between said least one locking tab and said first top wall to provide a resilient connection between said at least one locking tab and said first top wall.  
   
   
       11 . The telescopic tool support as claimed in  claim 9 , wherein a pivot device is disposed between said at least one locking tab and said first top wall, to provide a pivot connection between said at least one locking tab and said first top wall.  
   
   
       12 . The telescopic tool support as claimed in  claim 2 , wherein said at least one locking tab ( 13 ) is resiliently connected to a first top wall ( 11 ) of said seat ( 10 ), said seat further comprises a front-end wall, and said front-end wall ( 15 ) comprises at least on fixing hole ( 16 ) for the passing and supporting of said latch ( 32 ) when said latch ( 32 ) slides along said sleeve between said unlocked position and said locked position.  
   
   
       13 . The telescopic tool support as claimed in  claim 1 , further comprising at least one stopper ( 70 ) for limiting the movement of said at least one locking tab ( 13 ) so as to prevent said locking tab from being overbent inward.  
   
   
       14 . The telescopic tool support as claimed in  claim 5 , wherein said racks ( 23 ) is in the form of a toothed structure with teeth that are connected to each other, spaced with each other or grouped into segments.
