  • the commodity 400 is released from the clip 33b by its own weight and dropped.
  • the sprocket 31b is referred to as the suspension-releasing mechanism.
  • the dropped commodity 400 is then collided with the curved top wall of the cover 35 and moved or fed horizontally along the top wall and toward the end of the cover 35 and finally dropped.
  • the commodity 400 is dropped to the receiver (not shown) located at a lower portion of the commodity discharge apparatus without any contact with the lower parts of the commodity discharge apparatus.
  • the user can take out the commodity 400 in the receiver in the vending machine after opening a shutter (not shown) of the machine.
  • the commodity suspension member 33 which has released the engagement with the commodity 400 is then moved to the upper feed portion of the chain 32 along with the movement of the chain 32.
  • both the endless chain 32 and the commodity suspension member 33 are vertically supported by the guide rail 36, the middle stepped portion 34c and the rail 34d.
  • the upper end of the commodity 400 is contacted, at the position adjacent to the sprocket 31b, with the lower end of the U-shaped side wall 35b of the cover 35 and thus the commodity 400 is prevented from being moved upward. Therefore, release of the commodity 400 from the clip 33b is enhanced so that a smooth operation of the release of the commodity can be attained. Thus, the commodity 400 can be prevented from being caught in the upper feed portion of the endless chain 32.
  • the commodity suspension member 33 is affixed to the endless chain 32 in such a state that the two pins 32a of the endless chain 32 are inserted through the two through-holes 33a' and the two through-holes 33e' of the clip fixture plate 33c. Therefore, attachment and detachment of the commodity suspension member 33 to the endless chain 32 is easily proceeded, and a pitch or interval of the adjacent commodity suspension members 33 can be easily changed in accordance with the size of the commodity.
  • the commodity suspension member 33 affixed to the endless chain 32 at the opposite ends of the endless chain 32 and, therefore, the commodities can be fed in a stable manner relative to a case that the commodity suspension member is affixed at one end of the endless chain 32 with less swinging movement of the commodities.
  • the commodity 400 is grasped by and suspended from the clip 33b of the commodity suspension member 33 and, therefore, the commodity 400 is kept stable with less swinging movement during its travel, relative to the case in which the commodity 400 is suspended from the hook.
  • the lower feed portion of the endless chain 32 is supported vertically by the bottom wall 34a of the casing 34 and the bottom wall 36a of the guide rail 36 and, therefore, the endless chain 32 is not dangled or loosened downwardly by receiving a load of the commodities 400.
  • a regular engagement is assured between the endless chain 32 and the sprockets 31a and 31b.
  • a smooth rotation of the sprockets 31a, 31b are assured and an increase in driving energy of the endless chain is restricted effectively.
  • a part 4c of the side wall of the casing 4 adjacent to the sprocket la can be made removable from the remaining portion of the side wall.
  • attachment and detachment of the commodity suspension member 3 to and from the endless chain can be made smoothly without any difficulty and, moreover, a pitch change of the commodity suspension members 3 can be readily and successfully proceeded.
  • an oblong through-hole 3a' a part of which is cut out can be formed to a main body 3a of the commodity suspension member 3.
  • the commodity suspension member 3 can be readily attached to and detached from the endless chain 2, and a pitch of the commodity suspension member 3 can be readily changed in accordance with the size of the commodity 100.
  • the commodity suspension member 3 can be formed such that its main body 3a is provided with a single through-hole 3a' and two shoulder portions 3a1, or otherwise, as shown in Fig. 20, it may be provided with a single through-hole 3a' and a single oblong through-hole 3a'.
  • This modification can be applied also to the second to fourth embodiments of the invention.
  • release of the commodity from the commodity suspension member at one end portion of the endless chain can be enhanced by means of the release enhancement mechanism so that the commodity can be released from the suspension members at one end portion of the endless chain.
  • the commodity can be prevented from being caught in the upper feed portion of the endless chain.
  • the endless chain is not dangled or loosened by loads of the suspended commodities.
  • a reliable engagement between the endless chain and the sprocket can be assured as well as a smooth rotational movement of the sprocket and, further, an increase in driving energy of the endless chain can be restricted or minimized effectively.
