a base (109) adjacent to said blocking lever and movable forwards and rearwards relative to said blocking lever parallel to movement of said drive belt, said base and said drive belt performing coordinated movement; the base controlled by an electronic device programmed to command;
A distribution lever (101) mounted on the base and movable forward and rearward relative to the stack of carts (201), wherein the distribution lever moves the new cart (202) of the plurality of carts. said dispensing lever having an open position that blocks movement relative to said first cart and a closed position that allows said new cart to be added to said stack and a cart to be dispensed from said stack;
a dual lever mechanism (100) comprising
The device , wherein the open position is a raised position and the closed position is a lowered position .

The dual lever mechanism is
said distribution lever is raised to an open position to block said new cart and a lock lever is lowered to a closed position to allow said new cart to be moved into said stack;
forward movement of the base causes the distribution lever to push the new cart into the stack;
movement of the drive belt along the base moves the stack of carts forward to make room for the new cart;
said locking lever is lifted to said open position to block said new cart;
the base and distribution lever move to their respective initial positions;
when receiving the cart into the stack;
A device according to claim 1 .

At least one of the distribution lever and the blocking lever may be curved, hooked, and/or shaped to further retain the cart bar and prevent the cart from being pulled upwards. having any other shape capable of holding a portion of
A device according to claim 1 .

The dual lever mechanism is
a distribution lever is lifted to an open position to block the first cart of the stack;
said blocking lever lowers to a closed position to move said first cart and said distribution lever in turn blocks said first cart;
the drive belt then moves the stack of carts rearward so that the first cart is blocked by the distribution lever;
the locking lever is then raised to an open position to block the next cart (204) in the stack, thereby preventing it from being pulled out of the stack;
lowering the dispensing lever to a closed position so that the first cart can be removed ;
Dispensing carts from the stack when
A device according to claim 1 .

2. The apparatus of claim 1, wherein the drive belt further comprises a chain for moving the stack of carts .

2. The apparatus of claim 1, further comprising a clasp (115) coupled to the drive belt and retaining the last cart in the stack which is a locking cart (203) .

5. Apparatus according to claim 4, wherein the distribution lever is coupled to the engine (103) by a series of shafts that convert rotational motion of the engine (103) into movement of the lever.

5. Apparatus according to claim 4, wherein said blocking lever is coupled to said engine (104) by a series of shafts which effect said change of attitude of said blocking lever in accordance with operation of said engine (104).

2. Apparatus according to claim 1, wherein the base is moved forward and backward by an engine (110) via a linear actuator (111) .

10. Apparatus according to claim 9 , wherein the base moves forward and backward on a track (108) .

The apparatus of claim 1, wherein movement of said base and said drive belt is detected by at least one sensor (116) .

12. Apparatus according to claim 11 , wherein the drive belt is moved by a belt wheel (113) operated by a belt engine.

2. Apparatus according to claim 1 , further comprising a housing (117) having a slit (118) for the distribution lever and a slit (119) for the blocking lever .

A method of accepting a cart into a cart stack, comprising:
An initialization step of placing the blocking lever (102) in the open position and locking the first cart (201) to said stack, with the distribution lever (101) in the closed position on the base in the rearward position. When,
holding a first cart (201) of a plurality of carts arranged in a stack by a blocking lever (102), said blocking lever being in an open position so that said first cart is held by said wherein the blocking lever prevents movement out of the stack;
positioning a new cart at the end of the stack;
changing the position of a locking lever from the open position to the closed position, wherein the distribution lever blocks the new cart from being pulled out of the stack;
changing the position of the blocking lever from the open position to the closed position so that a new cart (202) can be inserted into the stack;
moving the dispensing lever forward to push the new cart into the stack;
moving the base forward so that the distribution lever pushes the new cart into the stack and a drive belt (112) follows the base and is moved by the engine to create space for the new cart; The movement of said base and said drive belt may be operated by one or more engines and said lever may be operated by an engine controlled by an electronic device programmed to command the execution of coordinated movements. When,
changing the position of the blocking lever from the closed position to the open position, such that the blocking lever prevents a second cart from moving out of the stack;
changing an orientation of the distribution lever from the open orientation to the closed orientation, wherein the distribution lever is moved rearwardly by the base;
the open position is a raised position and the closed position is a lowered position;
Method.

A method of dispensing carts from a cart stack, comprising:
An initialization step of placing the blocking lever (102) in the open position and locking the first cart (201) to said stack, with the distribution lever (101) in the closed position on the base in the rearward position. When,
holding a first cart of a plurality of carts arranged in a stack by a blocking lever, said blocking lever being in an open position so that said first cart is withdrawn rearwardly from said stack. a step in which the blocking lever prevents
changing the posture of the distribution lever from the closed posture to the open posture;
changing the posture of the block lever from the open posture to the closed posture;
driving the plurality of carts rearwardly by a drive belt (112) to drive the stack of carts rearwardly via a locking cart (203), wherein the first cart is pulled rearwardly from the stack; said distributing lever preventing the
