[0043] Features and advantages of embodiments of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which like reference numerals identify corresponding elements. DETAILED DESCRIPTION

[0044] The present invention will now be described in detail with reference to the embodiments of the invention as shown in the accompanying drawings. References to "one embodiment", "embodiment", "exemplary embodiment", etc. indicate that the described embodiment may include specific features, structures or characteristics, but each embodiment may not necessarily include the specific features, structures or characteristics. Moreover, such phrases do not necessarily refer to the same embodiment. In addition, when specific features, structures or characteristics are described in conjunction with an embodiment, whether or not explicitly described, it is considered that those skilled in the art can implement these features, structures or characteristics in conjunction with other embodiments.

[0045] Vending machines are used to store products (e.g., bottled, canned, or boxed beverages, etc.) and deliver these products to consumers. Conventional vending machines often deliver products by dropping the products into a pickup space, and the consumer opens, for example, a hinged door of the pickup space to retrieve the products. However, seeing and / or hearing the product being dropped may be unpleasant to the consumer. In addition, dropping certain products (e.g., carbonated beverages) may make the product volatile when opened. Presenting the product to the consumer rather than dropping it will improve the quality of the product and provide a better user experience.

[0046] While some vending machines do not dispense product, these vending machines require a high level of care and maintenance. Therefore, it is desirable to provide a vending machine that presents product to a consumer but reduces the complexity of other vending machines (e.g., lean-on vending machines). In addition, it is desirable to accommodate products of various shapes (e.g., cylindrical, square) and sizes while also providing simple product loading.

[0047] Thus, in some embodiments, a lean-to vending machine includes a storage system, a delivery system, and a delivery area. These components interact with each other to distribute, deliver, and present the products to consumers without any placement. In some embodiments, these interactions are primarily mechanical, thereby reducing the complexity of the vending machine and reducing the need for maintenance and upkeep.

[0048] In some embodiments, the storage system is modular. In some embodiments, the storage system includes one or more racks. In some embodiments, a plurality of racks form a grid of product storage areas. In some embodiments, each rack is configured to dispense vending products. For example, each rack may include a mechanism for dispensing vending products, such as a spring-loaded product pusher. For another example, each rack may be angled downward so that gravity assists and / or pulls the vending product out of the rack. In some embodiments, each rack is flat. In some embodiments, each rack includes a door that holds the vending product on the rack until the vending machine is ready to dispense the vending product.

[0049] In some embodiments, the delivery system includes an XY mechanism and a delivery cup. In some embodiments, the XY mechanism moves the delivery cup in an X direction and a Y direction, thereby allowing the delivery cup to be positioned adjacent to the shelf to receive the vending product and then repositioned to the delivery area to present the vending product to the consumer. In some embodiments, the XY mechanism includes a lead screw and nut assembly.

[0050] In some embodiments, the delivery cup is coupled to the XY mechanism and includes a platform for supporting the vending product. In some embodiments, the delivery cup is in communication with the rack. In some embodiments, the delivery cup is in communication with the rack to properly position the delivery cup. In some embodiments, the delivery cup interacts with the rack to open the gate, thereby allowing one of the vending products to be dispensed onto or into the delivery cup. For example, the delivery cup may include an actuator for opening the gate. In some embodiments, the delivery cup opens the gate by using a solenoid to actuate a plunger.

[0051] In some embodiments, the delivery area includes an extraction position for consumers to extract vending products. In some embodiments, the delivery area includes an outer door that isolates the delivery area from the outside of the vending machine. In some embodiments, when the delivery cup enters the delivery area, the delivery cup interacts mechanically with the delivery area so that the consumer touches the vending product, thereby presenting the vending product to the consumer. In some embodiments, the mechanical interaction rotates the delivery cup, opens the inner door, unlocks the inner door, and / or opens the outer door of the delivery area. In some embodiments, the mechanical interaction includes the interaction between the pinion and the rack. In some embodiments, the mechanical interaction includes the interaction between the push surface and the protrusion protruding through the slot. In some embodiments, the mechanical interaction includes the interaction between the protrusion and the locking mechanism. In some embodiments, the mechanical interaction includes the force acting directly on the inner door.

[0052] Vending products may include beverages, such as bottled water, energy drinks, carbonated soft drinks, milk, juice, sports drinks, etc., and food, such as French fries, granola bars, energy bars, sandwiches, ice cream bars, candies, and other snacks. Vending products may be packaged in different sizes, shapes, and styles. Therefore, although beverages are mainly discussed herein, the disclosed principles are also applicable to other types of vending products. The leaning vending machine disclosed herein can be used in any environment (e.g., school campus, store, shopping mall, office, etc.).

[0053] These and other embodiments are discussed below with reference to the accompanying drawings. However, those skilled in the art will appreciate that the specific embodiments given herein with respect to these drawings are for illustration purposes only and should not be construed as limiting.

[0054] In some embodiments, for example, Figure 1As shown, the vending machine 10 includes an outer body 14. The outer body 14 is made of multiple pieces (such as side panels, rear panels, front panels, top panels or bottom panels), or can be constructed by any method known in the art without departing from the present invention. In some embodiments, the vending machine 10 includes a front panel 16. In some embodiments, the front panel 16 is transparent. In some embodiments, the front panel 16 is glass (e.g., single-layer or double-layer). In some embodiments, the front panel 16 is transparent plastic. In some embodiments, the size and shape of the front panel 16 are set to allow consumers to see the vending products 12 stored in the vending machine 10.

[0055] In some embodiments, the vending machine 10 includes a user interface 18. In some embodiments, the user interface 18 includes a keypad and / or a touch screen, which can be used, for example, to select a desired vending product 12 or input information (such as a PIN). In some embodiments, the user interface 18 includes a payment mechanism. For example, the user interface 18 may include a currency receiving area (e.g., banknotes and / or coin slots), a card reader (e.g., for reading credit cards, debit cards, ID cards, etc. by swiping a card) and one or more of a contactless payment mechanism (e.g., a mechanism based on RFID, QR code, NFC, Bluetooth, etc.). In some embodiments, the user interface 18 includes a payment return mechanism, such as a banknote and / or coin return portion. In some embodiments, the user interface 18 is disposed adjacent to the front panel 16. In some embodiments, the user interface 18 is surrounded by a plastic cover 19.

[0056] In some embodiments, the vending machine 10 is used to vend one or more vending products 12. In some embodiments, the vending products 12 can each be the same type of product (e.g., bottled water). In some embodiments, the vending machine 10 can include multiple vending products 12 (e.g., bottled water, different flavors of soft drinks, juice, etc.).

[0057] In some embodiments, the vending machine 10 includes a storage space 20. For example, the storage space 20 can be located within the exterior body 14. In some embodiments, the storage space 20 includes a space visible through the front panel 16. In some embodiments, the vending machine 10 stores vending products 12 within the storage space 20. In some embodiments, the vending machine 10 can store the vending products 12 on a plurality of racks 300 within the storage space 20. In some embodiments, each rack 300 can be dedicated to a particular type of vending product 12.

[0058] In some embodiments, the vending machine 10 includes a delivery area 400. In some embodiments, the delivery area 400 is configured to present the vending product 12 to the consumer. In some embodiments, the delivery area 400 is surrounded by a plastic cover 19. In some embodiments, the delivery area 400 is disposed adjacent to the user interface 18 (e.g., below the user interface). In some embodiments, the delivery area 400 includes an outer door 410. When closed, the outer door 410 can isolate the delivery area 400 from the exterior of the vending machine 10.

[0059] In some embodiments, for example, Figure 2 As shown, the vending machine 10 includes a delivery system 100 that delivers the vending product 12 from the rack 300 to the delivery area 400. In some embodiments, the delivery system 100 is disposed between the front panel 16 and the rack 300. In some embodiments, the delivery system 100 includes an XY mechanism and a delivery cup 200. In some embodiments, the XY mechanism of the delivery system 100 is configured to move the delivery cup 200 to any position in the plane of the delivery cup within the storage space 20, thereby allowing the delivery cup 200 to be positioned adjacent to any one of the plurality of racks 300 and positioned in the delivery area 400.

[0060] In some embodiments, the XY mechanism of the delivery system 100 is attached to the vending machine 10 via a support bracket 102. In some embodiments, the support bracket 102 can be disposed at a corner of the XY mechanism. In some embodiments, the XY mechanism includes a support rod 104 that provides additional support to secure the XY mechanism within the vending machine 10. In some embodiments, the support rod 104 can be disposed near the top of the vending machine 10.

[0061] In some embodiments, the XY mechanism of the delivery system 100 includes a system of a lead screw and a nut assembly. In some embodiments, the nut assembly includes a component (e.g., a bracket) that attaches the lead screw to an element that will move along the lead screw (e.g., a delivery cup 200, another lead screw, etc.). The component can be screwed onto the internal portion so that when the lead screw rotates, the component moves along the lead screw. Hereinafter, this relationship is referred to as a nut configuration.

[0062] In some embodiments, the XY mechanism includes a bottom horizontal lead screw 105, a top horizontal lead screw 110, and a vertical lead screw 120. In some embodiments, the bottom horizontal lead screw 105 is disposed near the bottom of the vending machine 10. In some embodiments, the bottom horizontal lead screw 105 is disposed below the bottom of the front panel 16 out of sight of the consumer. In some embodiments, the top horizontal lead screw 110 is disposed near the top of the vending machine 10. In some embodiments, the top horizontal lead screw 110 is disposed above the top of the front panel 16 out of sight of the consumer. In some embodiments, the top horizontal lead screw 110 is coupled to and driven by a motor 114 (see Figure 3 ). In some embodiments, the motor 114 is disposed within the motor box 130. In some embodiments, the motor 114 comprises a DC motor. In some embodiments, the bottom horizontal lead screw 105 is also coupled to the motor 114 and driven by the motor. In some embodiments, the bottom horizontal lead screw 105 is indirectly coupled to the motor 114.

[0063] In some embodiments, the movement of the top horizontal lead screw 110 is transmitted to the bottom horizontal lead screw 105 via the transmission rod 112. For example, Figure 4 As shown, the transmission gear 111 can be coupled to the top horizontal lead screw 110, and the transmission gear 113 can be coupled to the transmission rod 112. The transmission gear 111 can engage the transmission gear 113 so that when the top horizontal lead screw 110 rotates, the transmission rod 112 also rotates. Figure 6 As shown, the drive gear 109 can be coupled to the drive rod 112, and the drive gear 107 can be coupled to the bottom horizontal lead screw 105. The drive gear 109 can engage the drive gear 107 so that when the drive rod 112 rotates, the bottom horizontal lead screw 105 also rotates. In some embodiments, the top horizontal lead screw 110 and the bottom horizontal lead screw 105 rotate at the same speed. For example, the gear ratio between the drive gear 111 and the drive gear 113 can be 1:1, and the gear ratio between the drive gear 109 and the drive gear 107 can also be 1:1. In some embodiments, the drive rod 112 is disposed on a side of the vending machine 10 opposite to the delivery area 400. In some embodiments, the drive rod 112 is disposed on the left side of the front panel 16 out of the sight of the consumer.

[0064] In some embodiments, the vertical lead screw 120 is coupled to the top horizontal lead screw 110 and the bottom horizontal lead screw 105, such as Figure 5 and Figure 7As shown, a nut configuration is used so that when the top horizontal lead screw 110 and the bottom horizontal lead screw 105 rotate, the vertical lead screw 120 moves along the top horizontal lead screw 110 and the bottom horizontal lead screw 105. In some embodiments, the vertical lead screw 120 is coupled to a motor 124 (see Figures 2 to 3 In some embodiments, the vertical lead screw 120 is indirectly coupled to the motor 124 via the drive rod 122. For example, Figure 5 As shown, the transmission gear 121 can be coupled to the transmission rod 122, and the transmission gear 123 can be coupled to the vertical lead screw 120. The transmission gear 121 can engage the transmission gear 123 so that when the transmission rod 122 rotates, the vertical lead screw 120 also rotates. In some embodiments, the transmission rod 122 is disposed adjacent to the top horizontal lead screw 110. Thus, in some embodiments, the transmission rod 122 is disposed above the top of the front panel 16 out of the sight of the consumer. In some embodiments, the transmission rod 122 is square.

[0065] In some embodiments, motor 124 is disposed adjacent to motor 114. In some embodiments, motor 124 is disposed within motor housing 130. In some embodiments, motor 124 comprises a DC motor. In some embodiments, motor housing 130 comprises isolation portion 132, such as Figure 3 1, wherein the motor box 130 is removed. In some embodiments, the isolation portion 132 can reduce the noise of the motors 114 and 124 heard by the consumer. In some embodiments, the motor box 130 is arranged outside the consumer's sight. For example, the motor box 130 can be arranged in the upper right corner (i.e., the right side and / or above the edge of the front panel 16). Therefore, in some embodiments, the motor box 130 can be arranged outside the storage space 20. In some embodiments, the motors 114 and 124 are controlled by a controller. For example, the motors 114 and 124 can receive signals from the controller to move the delivery cup 200 in the X direction by a certain amount and in the Y direction by a certain amount. The signal from the controller can be based on the consumer's selection of a specific vending product 12 via the user interface 18. The controller can be a single controller that controls both motors 114 and 124, or the controller can be two separate controllers that control motors 114 and 124 separately.

[0066] In some embodiments, support beams 140 are coupled to vertical lead screw 120. In some embodiments, support beams 140 operate to provide additional structural support to vertical lead screw 120. In some embodiments, support beams 140 operate to hide certain portions of the XY mechanism (e.g., vertical lead screw 120, electrical connections, brackets, etc.) from view of a consumer.

[0067] In some embodiments, the delivery cup 200 of the delivery system 100 is coupled to the vertical lead screw 120, such as Figure 2 and Figure 8 As shown, a nut configuration is used so that when the vertical lead screw 120 rotates, the delivery cup 200 rotates along the vertical lead screw 120. Therefore, when the top horizontal lead screw 110 and the bottom horizontal lead screw 105 rotate, the vertical lead screw 120 rotates in the X direction, and the delivery cup 200 can move in the Y direction (together with the vertical lead screw 120 and the support beam 140). Therefore, the delivery cup 200 can be accurately and reliably positioned at any one of the racks 300 and the delivery area 400 based on the signals received by the controller that controls the motors 114 and 124. In some embodiments, other types of XY mechanisms can be used instead of the system of lead screws and nut assemblies to accurately position the delivery cup 200.

[0068] In some embodiments, the delivery cup 200 is configured to receive the vending product 12 from the rack 300 and transport the vending product 12 to the delivery area 400. In some embodiments, the delivery cup 200 is configured to interact with the rack 300. In some embodiments, the delivery cup 200 can be in communication with the rack 300, and vice versa. For example, the rack 300 can send a signal to the delivery cup 200 indicating that the delivery cup 200 has arrived at the appropriate position. As another example, the delivery cup 200 can send a signal to the rack 300 that the delivery cup 200 is ready to receive the vending product 12. The signal between the delivery cup 200 and the rack 300 can utilize, for example, RFID, NFC, or Bluetooth technology. In some embodiments, the delivery cup 200 may include an actuator that causes the rack 300 to dispense the vending product 12. In some embodiments, the actuator includes a mechanical actuator.

[0069] In some embodiments, the delivery cup 200 is configured to interact with the delivery area 400. In some embodiments, the interaction between the delivery cup 200 and the delivery area 400 allows the consumer to easily access the vending product 12 within the delivery area 400. In some embodiments, the interaction between the delivery cup 200 and the delivery area 400 opens the outer door 410. In some embodiments, the delivery cup 200 is configured to mechanically interact with the delivery area 400. In some embodiments, the mechanical interaction between the delivery cup 200 and the delivery area 400 causes the outer door 410 to open. In some embodiments, the mechanical interaction between the delivery cup 200 and the delivery area 400 causes the delivery area 400 and / or other components of the delivery cup 200 to move to provide the consumer with better access to the vending product 12. In some embodiments, the mechanical interaction between the delivery cup 200 and the delivery area 400 effectively presents the vending product 12 to the consumer.

[0070] In some embodiments, for example, Figures 8 to 10 As shown, the delivery cup 200 includes a container 210 and a platform 220. In some embodiments, the container 210 is transparent, thereby allowing the consumer to see the vending product 12 as it is transported to the delivery area 400. In some embodiments, the container 210 has an open side 212. In some embodiments, the open side 212 is configured to face the shelf 300. In some embodiments, the container 210 is configured to rotate relative to the platform 220. For example, as will be described more fully below, the container 210 can be rotated 180 degrees when entering the delivery area 400 so that the open side 212 faces the consumer, thereby facilitating the consumer's access to the vending product 12.

[0071] In some embodiments, the platform 220 supports the container 210. In some embodiments, the platform 220 includes features that facilitate consumer access to the vending product 12. These features may include a push surface 222, a protrusion 224, and / or a pinion 226 (see Fig.10 ). In some embodiments, the push surface 222 can open the outer door 410, as will be described more fully below. In some embodiments, the protrusion 224 can unlock the inner door 420 of the delivery area 400, as will be described more fully below. In some embodiments, the pinion 226 can interact with the rack 430 of the delivery area 400 to rotate the container 210, as will be described more fully below. Therefore, in some embodiments, the pinion 226 is coupled to the container 210 so that the rotation of the pinion 226 is associated with the rotation of the container 210.

[0072] In some embodiments, the delivery cup 200 includes a sensor 230 that senses whether the vending product 12 is within the delivery cup 200 (i.e., the sensor 230 can sense the presence or absence of the vending product 12 within the delivery cup 200). In some embodiments, the sensor 230 includes an ultrasonic sensor. In some embodiments, the container 210 includes a hole 214 that facilitates the sensor 230 sensing the vending product 12. In some embodiments, the container 210 includes two holes 214 on opposite sides so that the sensor 230 can sense when the vending product 12 is received from the rack 300 (i.e., before rotating 180 degrees), and can sense when the consumer removes the vending product 12 in the delivery area 400 (i.e., after rotating 180 degrees).

[0073] In some embodiments, the movement of the delivery cup 200 may be based on the sensor 230 sensing the vending product 12 (or the absence of the vending product). For example, the delivery cup 200 may remain in the delivery area 400 until the delivery cup senses the absence of the vending product 12 (indicating that the consumer has retrieved the vending product 12). As another example, the delivery cup 200 may remain next to the rack 300 until the delivery cup senses the vending product 12 (indicating that the vending product 12 is ready to be transported to the delivery area 400). In some embodiments, a different type of sensor may be used in place of the sensor 230 in the same or different location. For example, a pressure sensor may be used to sense the presence of the vending product 12 by the weight of the container 210 and any objects therein.

[0074] In some embodiments, the delivery cup 200 includes features that facilitate dispensing of the vending product 12 from the rack 300. For example, as described above, the delivery cup 200 and the rack 300 can send signals to communicate that the delivery cup 200 is properly positioned relative to the rack 300. In some embodiments, the delivery cup 200 can include an actuator. In some embodiments, the actuator can send a signal to cause the rack 300 to dispense the vending product 12. In some embodiments, the signal can be sent via RFID, NFC, or Bluetooth technology. In some embodiments, the actuator can include a mechanical actuator. In some embodiments, the actuator includes a solenoid 240 and a plunger 242, such as Fig.10 In some embodiments, the solenoid 240 actuates the plunger 242. In some embodiments, when the plunger 242 is actuated, the plunger 242 interacts with the rack 300, as will be described more fully below, to allow the rack 300 to dispense a vending product 12 into the delivery cup 200. In some embodiments, the solenoid 240 actuates the plunger 242 to obtain a timed pulse.

[0075] In some embodiments, for example, Fig.11 As shown, the rack 300 includes a product storage area 305, a product pusher 310, and a door 320. Fig.11 Only one rack 300 is shown, but the vending machine 10 may include multiple racks 300. In some embodiments, the racks 300 are modular. In some embodiments, the racks 300 may be positioned in a grid (i.e., adjacent racks 300 are arranged vertically in single and multiple rows of racks 300). In some embodiments, the product storage area 305 is configured to receive a variety of vending products 12 having different shapes and sizes. In some embodiments, the vending products 12 are loaded into the product storage area 305 by pushing the vending products through the gate 320 against the product pusher 310.

[0076] In some embodiments, product pusher 310 is configured to slide along rack 300 via sliding member 312, such as Fig.12 In some embodiments, for example, Fig.13 As shown, the sliding member 312 can slide along the guide rail 302 of the frame 300. Fig.12 As shown, the product pusher 310 can be biased to the front portion of the shelf 300. When the vending product 12 is inserted into the product storage area 305, the product pusher 310 is pushed toward the rear of the shelf 300. In some embodiments, the product pusher 310 is spring loaded and thus tends to push the vending product 12 out of the product storage area 305. For example, the product pusher 310 can be biased to the front portion of the shelf 300 with a spring 314 (see Figure 14 to Figure 15 ). In some embodiments, the spring 314 comprises a constant force spring. When the product pusher 310 is at the front of the rack 300, the spring 314 can be fully rolled up. When the vending product 12 is inserted into the product storage area 305, the product pusher 310 is pushed back, thereby unrolling the spring 314. The unrolled spring 314 exerts a force on the product pusher 310, which pushes the vending product 12. In some embodiments, the rack 300 is flat or horizontal, for example, the rack 300 can be parallel with respect to the floor or with respect to the base of the vending machine 10. In some embodiments, the rack 300 is angled downward toward the delivery cup 200 (i.e., toward the front of the vending machine 10). Therefore, gravity can also exert a force on the vending products 12 to move these vending products out of the product storage area 305.

[0077] In some embodiments, the gate 320 operates to keep the vending product 12 within the product storage area 305. In some embodiments, the gate 320 includes two side gates 320 (see Fig.11 , Figures 14 to 16 ). The size of the gate 320 can be set based on the smallest vending product 12 to be stored in the vending machine 10. Therefore, the gate 320 can keep any size of vending products 12 within the product storage area 305. In some embodiments, two side gates 320 are provided on the sides of the rack 300. For example, one side gate 320 can be provided on each side of the rack 300. In some embodiments, the two side gates 320 only partially extend inward from each side of the rack 300. In some embodiments, the rack 300 includes a sensor, such as an optical sensor, for determining the size of the vending product 12 within the product storage area 305.

[0078] In some embodiments, the door 320 is hinged. In some embodiments, the door 320 is spring loaded into a closed position. Fig.13As shown, springs 325 may be included in the frame 300 to hold the door 320 in a closed position. In some embodiments, the door 320 may be mechanically connected to the front plate 322, the bottom plate 324, and the side bars 326 (see Fig.13 and Fig.16 ). In some embodiments, the front plate 322 is disposed at the bottom of the front side of the rack 300 facing the delivery cup 200. In some embodiments, the front plate 322 is configured to be pushed into the rack 300. In some embodiments, the plunger 242 of the delivery cup 200 is configured to push the front plate 322 into the rack 300. In some embodiments, when the front plate 322 is pushed in, the bottom plate 324 and the side rod 326 are also pushed back. In some embodiments, the side rod 326 slides in the narrow slot 329. In some embodiments, the connecting rod 328 connects the side rod 326 with the door 320. Therefore, when the side rod 326 slides backward in the narrow slot 329, the connecting rod 328 is pulled back, thereby swinging the door 320 open.

[0079] In some embodiments, once the front plate 322 is released, the front plate 322 returns to its original position due to the force applied by the spring 325. In some embodiments, the gate 320 is only kept open for a time sufficient to dispense a vending product 12 from the rack 300. In some embodiments, the timing pulse of the solenoid 240 is long enough to allow a vending product 12 to be dispensed from the rack 300. In some embodiments, the duration of the timing pulse varies and may be based on the size of the vending product 12. In some embodiments, the duration of the timing pulse is the same for each vending product 12, regardless of size. In some embodiments, the timing pulse is less than one second (e.g., 0.2 seconds to 0.5 seconds). In some embodiments, the rack 300 includes an optical sensor configured to sense when the gate 320 is fully opened. In some embodiments, the optical sensor is configured to send a signal to the solenoid 240. In some embodiments, the timing pulse begins when the solenoid 240 receives a signal that the gate 320 is fully opened. Similar timing pulses or timed pulses may occur in embodiments where the actuator is not a solenoid and plunger configuration.

[0080] In some embodiments, after the delivery cup 200 receives the vending product 12 from the rack 300, the delivery cup 200 transports the vending product 12 to the delivery area 400. In some embodiments, the delivery area 400 includes an area where a consumer can extract the vending product 12. In some embodiments, for example, Fig.17 As shown, delivery area 400 includes an outer door 410 and an inner door 420 .

[0081] In some embodiments, the outer door 410 comprises a door that, when the outer door 410 is closed (ie, in the closed configuration 450 (see Fig.18A )), the door isolates the delivery area 400 from the exterior of the vending machine 10. In some embodiments, when the exterior door 410 is open (i.e., in the open configuration 460 (see Fig.18B )), an opening 462 is formed, thereby allowing a consumer to access the delivery area 400 so that the vending product 12 can be extracted. In some embodiments, the outer door 410 moves from the closed configuration 450 to the open configuration 460 through mechanical interaction with the delivery cup 420. In some embodiments, the outer door 410 slides open. In some embodiments, the outer door 410 rotates open. In some embodiments, the outer door 410 opens in the direction 452, such as Fig.18A In some embodiments, the outer door 410 includes a bottom plate 412 and a top plate 414. In some embodiments, the bottom plate 412 and the top plate 414 connect the outer door 410 to the delivery area 400 via a rotatable attachment. In some embodiments, the attachment is spring loaded to bias the outer door 410 to be in the closed configuration 450.

[0082] In some embodiments, for example, Fig.19 As shown, the bottom plate 412 includes a protrusion 440 that protrudes into the delivery area 400. In some embodiments, the protrusion 440 protrudes through the slot 442. In some embodiments, the slot 442 is curved. In some embodiments, the pushing surface 222 of the delivery cup 200 is configured to push the protrusion 440 along the slot 442. In some embodiments, when the protrusion 440 moves along the slot 442, the outer door 410 opens.

[0083] In some embodiments, for example, Fig.19As shown, the rack 430 is disposed in a fixed manner within the delivery area 400. In some embodiments, the pinion 226 of the delivery cup 200 is configured to interact with the rack 430 when the delivery cup 200 enters the delivery area 400. The teeth of the rack 430 engage with the teeth of the pinion 226, thereby rotating the pinion 226 as the delivery cup 200 continues to move into the delivery area 400. In some embodiments, the rotation of the pinion 226 rotates the container 210, thereby presenting the vending product 12 to the consumer. In some embodiments, the interaction between the pinion 226 and the rack 430 and the interaction between the push surface 222 and the protrusion 440 occur almost simultaneously. For example, these interactions can be simultaneous, or these interactions can overlap at least partially in time. Therefore, in some embodiments, when the outer door 410 is opened (thereby allowing the consumer to see into the delivery area 400), the container 210 rotates. These combined movements can increase the effect or user experience of presenting the vending product 12 to the consumer. For example, after the outer door 410 is at least partially opened, the consumer can see that the container 210 has completed its rotation to present the vending product 12 to the consumer. In some embodiments, the vending product 12 rotates as the container 210 rotates.

[0084] In some embodiments, the inner door 420 isolates the delivery area 400 from the storage space 20 of the vending machine 10. In some embodiments, the inner door 420 comprises a hinged door. In some embodiments, the inner door 420 opens in a direction 454 to the delivery area 400, such as Fig.18A In some embodiments, the inner door 420 is pushed open by the delivery cup 200. In some embodiments, the inner door 420 is locked. For example, the inner door 420 may include a locking mechanism 422, such as Fig.19454. In some embodiments, the locking mechanism 422 prevents the inner door 420 from opening inward in the direction 454. In some embodiments, the locking mechanism 422 can be pressed downward to unlock the inner door 420. In some embodiments, the protrusion 224 of the delivery cup 200 is configured to interact with the locking mechanism 422 when the delivery cup 200 enters the delivery area 400. In some embodiments, the protrusion 224 extends farther than the rest of the delivery cup 200 (i.e., closer to the delivery area 400). Therefore, before the delivery cup 200 pushes the inner door 420 to open the inner door 420, the protrusion 224 can unlock the inner door 420 by pressing the locking mechanism 422 downward. In some embodiments, the inner door 420 can be unlocked via other mechanisms. For example, in some embodiments, the inner door 420 can be configured to unlock itself when the delivery cup 200 approaches. In some embodiments, when the delivery cup approaches the delivery area 400, the delivery cup 200 can send a signal to the inner door 420, for example using wireless communication technology such as RFID, Bluetooth, NFC, etc. Other interactions or mechanisms can also be used.

[0085] In some embodiments, the inner door 420 cannot be opened from within the delivery area 400. In some embodiments, the inner door 420 acts as an anti-tamper door to prevent theft. In some embodiments, the inner door 420 includes a horizontal shelf 424 (see Fig. 20A and Fig. 20B ) is used to prevent a person from pressing down the locking mechanism 422 to unlock the inner door 420.

[0086] FIG. 20A to FIG. 20G The interaction between the delivery cup 200 and the delivery area 400 is shown for unlocking and opening the inner door 420 and rotating the container 210 so that the vending product 12 is presented to the consumer. In some embodiments, the delivery cup 200 moves in a delivery cup entry direction 470 to enter the delivery area 400 and moves in a delivery cup exit direction 472 to exit the delivery area 400. In some embodiments, the inner door 420 is locked in a closed position, such as Fig. 20A In some embodiments, the horizontal shelf 424 can prevent a person from unlocking the inner door 420. In some embodiments, when the delivery cup 200 approaches the inner door 420, the delivery cup 200 unlocks the inner door 420 (e.g., via the protrusion 224, wireless communication, or other mechanism). In some embodiments, the delivery cup 200 begins to push the inner door 420 open, such as Fig. 20B In some embodiments, when the delivery cup 200 enters the delivery area 400, as shown in FIG. Fig. 20C As shown, the pinion 426 (in Fig. 20C (not visible) interacts with rack 430. In some embodiments, FIG. 20D to FIG. 20GAs shown, as the delivery cup 200 continues to enter the delivery area 400, the interaction between the pinion 426 and the rack 430 causes the container 210 to rotate in the delivery cup opening rotational direction 480. In some embodiments, the total possible rotation includes 180 degrees. In some embodiments, the delivery cup opening rotational direction 480 allows the open side 212 to rotate from facing the shelf 300 (i.e., away from the consumer) to facing the consumer (see Figure 20G In some embodiments, as the delivery cup 200 exits the delivery region 400, the interaction between the pinion 426 and the rack 430 causes the delivery cup 200 to rotate in the delivery cup approaching rotational direction 482.

[0087] Thus, the vending machine 10 can be used to present vending products 12 to consumers in a sophisticated but simple manner. In some embodiments, the consumer can pay and select the vending product 12 via the user interface 18 (e.g., a keypad, touch screen, and / or payment mechanism). In some embodiments, the user interface 18 can include a keypad or touch screen, a payment system (bills, coins, cards, etc.), a coin and / or bill return, a display screen, and other similar components. In some embodiments, the selection of the vending product 12 at the user interface 18 can be communicated to a controller that controls the motors 114 and 124. In some embodiments, based on the communication to the controller, the motors 114 and 124 operate to rotate the top horizontal lead screw 110, the bottom horizontal lead screw 105, and the vertical lead screw 120 so that the delivery cup 200 moves in the X direction and the Y direction to reach the appropriate rack 300 for the selected vending product 12.

[0088] In some embodiments, the delivery cup 200 moves to a preset position to receive the vending product 12. In some embodiments, the vending machine 10 knows when the delivery cup 200 is in the correct position based on control from the controller of the motors 114 and 124. In some embodiments, the vending machine 10 knows when the delivery cup 200 is in the correct position based on communication between the delivery cup 200 and the rack 300 (e.g., wireless communication technology such as RFID, Bluetooth, NFC, etc.).

[0089] In some embodiments, the delivery cup 200 actuates the gate 320 of the rack 300 to dispense one vending product 12 (e.g., via wireless communication techniques or via a mechanical actuator, such as a solenoid 240 and a plunger 242). In some embodiments, the gate 320 remains open based on a timed pulse sufficient to allow one vending product 12 to be dispensed from the rack 300.

[0090] In some embodiments, the delivery cup 200 senses when the vending product 12 is located within the delivery cup 200 (e.g., via a sensor 230, such as an ultrasonic sensor, or via a pressure sensor). In some embodiments, the delivery cup 200 communicates to the controller of the motors 114 and 124 that the vending product 12 has been loaded onto the delivery cup 200. In some embodiments, after the selected vending product 12 is loaded into the delivery cup 200, the controller drives the motors 114 and 124 to rotate the top horizontal lead screw 110, the bottom horizontal lead screw 105, and the vertical lead screw 120 so that the delivery cup 200 moves in the X and Y directions to reach the delivery area 400. In some embodiments, the delivery cup 200 interacts with the delivery area 400 to unlock and open the inner door 420, open the outer door 410, and rotate the container 210 (e.g., using the mechanisms described above). In some embodiments, the combination of these interactions presents the vending product 12 to the consumer and enables the consumer to reach and extract the selected vending product 12.

[0091] In some embodiments, the vending product 12 is presented to the consumer in an upright position. In some embodiments, the vending product 12 is presented to the consumer without requiring a drop. In some embodiments, the vending product 12 is presented to the consumer without requiring the consumer to open the exterior door 410 or manually open or push any aspect of the vending machine 10 other than the user interface 18 (e.g., for selecting and paying for the vending product 12). In some embodiments, the vending product 12 is presented to the consumer by rotating the vending product 12.

[0092] In some embodiments, the delivery cup 200 senses when the vending product 12 has been removed from the delivery cup 200 (e.g., via a sensor 230, such as an ultrasonic sensor, or via a pressure sensor). In some embodiments, the delivery cup 200 sends a signal to the controller of the motors 114 and 124 that the vending product 12 has been extracted. In some embodiments, after the vending product 12 has been extracted, the controller drives the motors 114 and 124 to rotate the top horizontal lead screw 110, the bottom horizontal lead screw 105, and the vertical lead screw 120 so that the delivery cup 200 moves in the X and Y directions to return to the starting position. In some embodiments, when the delivery cup 200 leaves the delivery area 400, the outer door 410 is closed, the container 210 is rotated back to the container's starting position, and the inner door 420 is closed and locked.

[0093] In some embodiments, if the consumer does not extract the vending product 12 after a predetermined amount of time, the controller can drive the motors 114 and 124 to rotate the top horizontal lead screw 110, the bottom horizontal lead screw 105, and the vertical lead screw 120 so that the delivery cup 200 moves in the X and Y directions to return to the delivery cup's starting position. When this occurs, the vending machine 10 can display (e.g., via the user interface 18) that the vending product 12 has not been extracted. The next consumer who approaches the vending machine 10 (sees this message) can use the user interface 18 to cause the vending machine 10 to dispense the loaded vending product 12 in the manner described above before another vending product 12 is selected.

[0094] In some embodiments, for example, Fig.21 As shown, the delivery area 400 includes a pickup sensor 490, such as, for example, a hand presence sensor 490. The hand presence sensor 490 can ensure that the delivery cup 200 will not begin to move while a consumer pickup is ongoing (e.g., while the consumer's hand is located in the delivery area 400). For example, if the sensor 230 does not sense the vending product 12 (i.e., senses that the vending product 12 has been removed), the delivery cup 200 can begin to return to the starting position, as described above. Similarly, after a predetermined amount of time, the delivery cup 200 can begin to return to the starting position even if the vending product 12 has not been picked up, as described above. However, if the hand presence sensor 490 senses that the consumer's hand is located in the delivery area 400 in any of these situations, the delivery cup 200 will delay returning to the starting position until the consumer's hand is no longer sensed in the delivery area 400.

[0095] In some embodiments, the hand presence sensor 490 includes a laser emitter 492 and a receiver 494. In some embodiments, the laser emitter 492 and the receiver 494 are disposed at a front portion of the delivery area 400 so that the consumer's hand is sensed if the hand is completely within the delivery area 400. Fig.21The laser emitter 492 is shown disposed above the receiver 494, but in some embodiments, the laser emitter 492 and the receiver 494 may be in opposite positions (i.e., the laser emitter 492 is below the receiver 494). In some embodiments, the hand presence sensor 490 includes two opposing mirrors 496, 498 on each side of the delivery area 400. In some embodiments, the laser emitter 492 transmits a light beam 495 that reflects back and forth between the mirrors 496, 498 until the receiver 494 receives the light beam 495. When the consumer's hand enters the delivery area 400, the hand will block the light beam 495 so that the light beam 495 cannot reach the receiver 494, thereby allowing the hand presence sensor 490 to determine when the consumer's hand is within the delivery area 400. In some embodiments, the laser emitter 492, the receiver 494, and the mirrors 496, 498 are positioned and angled to ensure that the hand will be sensed at any point along the entrance to the delivery area 400.

[0096] In some embodiments, the vending machine 10 includes a front door 30, such as Fig. 22 10. In some embodiments, the door 30, when opened, enables access to the storage space 20 and to the electrical system of the vending machine. In some embodiments, the door 30 can be opened to reload the vending product 12 to the rack 300, adjust the rack 300, or for other maintenance or service of the vending machine 10. In some embodiments, the door 30 includes a hinged door. In some embodiments, the door 30 includes a front panel 16. In some embodiments, the door 30 includes a plastic cover 19. In some embodiments, the plastic cover 19 houses the user interface 18. In some embodiments, the door 30 is modular, allowing the same door 30 to be used for vending machines with different user interfaces 18 (e.g., a keypad and a touch screen).

[0097] In some embodiments, the door 30 includes rollers 32, such as Fig.23 and Fig.24 In some embodiments, the roller 32 is disposed on an inner frame of the door 30. In some embodiments, the roller 32 is disposed on a bottom portion of the door 30. In some embodiments, the roller 32 may be fixedly attached to the door 30. In some embodiments, when the door 30 is closed, the roller 32 rests on a bracket 34 disposed on a bottom portion of the outer body 14, as shown. Fig.24 In some embodiments, this configuration can help align the door 30 to achieve an accurate closed position and proper sealing each time the door 30 is closed.

[0098] In some embodiments, the vending machine 10 includes a self-contained refrigeration unit 500, such as Fig.25In some embodiments, the refrigeration unit 500 includes a hot side 510 and a cold side 520. In some embodiments, the hot side 510 and the cold side 520 are sealed to prevent hot air and cold air from mixing. In some embodiments, the refrigeration unit 500 includes an insulating wall 515 separating the hot side 510 and the cold side 520.

[0099] In some embodiments, the hot side 510 includes a condenser 512, a compressor 514, and a fan 516. In some embodiments, air enters the hot side 510 via an air inlet 502 and exits the hot side 510 via an exhaust 504. In some embodiments, the cold side 520 includes an evaporator 522 and a fan 524. In some embodiments, cold air 506 flows out of the cold side 520 into the storage space 20 to cool the vending products 12. In some embodiments, warm air 508 returns from the storage space 20 to the cold side 520.

[0100] In some embodiments, the vending machine 10 includes a cover plate 530 disposed above the refrigeration unit 500, such as Fig.26 In some embodiments, the cover plate 530 is attached to the vending machine 10 to form a duct that carries the cool air 506 into the storage space 20 and carries the warm air 508 from the storage space 20 back to the refrigeration unit 500 .

[0101] In some embodiments, because the refrigeration unit 500 is self-contained, the refrigeration unit 500 can be easily removed and inserted for maintenance, service, or replacement. In some embodiments, the refrigeration unit 500 operates to maintain the vending product 12 at a suitable temperature.
