  • the holder 13 will preferably remain at the present position and will not interfere with the intermediate pull out channel 30 movement whenever the drawer is shoved into the respective furniture.
  • the drawer stopper of a second alternate mode is in the form of a lever as well, however is of altered structure than the stop device disclosed formerly. In this manner however, a holder is not required.
  • the stop device of this mode is accordingly fixed on the top surface of the intermediate pull out channel in a similar manner as the previous stop device.

  • a clip or clasp 20 like section for insertion into a recess or cavity which is provided on the intermediate pull out channel 30 at a predetermined length and subsequently locking the said lever onto the top surface of the intermediate pull out channel.
  • the operational effect of this particular mode is substantially similar to that of the formerly disclosed external stopper .
  • the lever of this mode is removed from the intermediate pull out channel 30 in a similar way to that of the formerly disclosed stopper.
  • a bending section or bending means 24 having a holder.
  • the bending section 24 is preferably formed from a resilient material, a durable plastic or rubber for instance into a reverse P - shaped cross section having a tab on the top portion of said P - shaped cross section defining a peg for example; having a holder 26.
  • the holder which defines the inlet of said peg is accordingly attached to said P - section and is inserted into a cavity provided on the intermediate pull out channel 30 in which the dimension of said aperture is slightly smaller in diameter to that of the resilient holder and extends through the said cavity or groove formed on the top surface of the intermediate pull out channel 30 for engagement to the roller means on said intermediate pull out channel and therefore limit further sliding movement of the intermediate pull out channel 30 and the outer pull out channel.
  • the peg In order to lock the stopper means of this mode onto the intermediate pull out channel 30, the peg is urged or forced into the inlet and therefore the inlet expands . Presumably, such expansion will lock the stopper of this mode to a stabilized position and all together hinder further sliding movement of the intermediate pull out channel and the outer pull out channel, due to the abutment mechanism incurred between the roller means on said intermediate channel and the protruding inlet: or holder.
