BRIEF DESCRIPTION OF PREFERRED EMBODIMENTS OF THE TECHNOLOGY RECEPTACLE

[0194] Referring first to FIGS. 1A and 1B, showing perspective views of a receptacle (100) according to an aspect of the present technology. The receptacle (100) is configured to be placed in an expanded configuration as shown in FIGS. 1A and 1n a contracted configuration as shown in FIG. 1B.

[0195] The expanded configuration facilitates delivery or sending of items (not shown in FIGS. 1A and 1B). However, in the contracted configuration at least one dimension of the receptacle (100) is reduced compared to when in the expanded configuration e.g. at least one of the height, the length and the width of the receptacle is reduced. This reduces the physical presence of the receptacle and its visibility when in the contracted configuration compared to the expanded configuration.

[0196] In the expanded configuration as shown in FIG. 1A the receptacle is substantially rectangular, while in the contracted configuration as shown in FIG. 1B the receptacle substantially resembles a floor mat. This is particularly useful because the receptacle (100) can be placed in front of a building and disguised as a floor mat (shown in FIGS. 2A and 2B) or entrance mat (shown in FIG. 4) when the receptacle (100) does not contain any items. As a result, the receptacle can comply with regulations or guidelines e.g. body corporate rules, while still enabling delivery and sending of items.

[0197] The placement of the receptacle (100) will help to ensure that in any configuration will not impede access into or out of a building relative to which it is placed.

[0198] Alternatively, as shown in FIGS. 2A, 2B and 2C, the receptacle (100) may be positioned against a wall (14) of a building. The receptacle (100) may be securely attached to at least one of the floor (16) or the wall (14). In the embodiment of FIG. 2A, the receptacle (100) is attached to the floor (16). In the alternative embodiment of FIG. 2C, the receptacle (100) is attached to the wall (14). In an embodiment, not shown in the Figures, the receptacle (100) may be attached to the wall (14) through a mounting bracket.

[0199] In another embodiment shown in FIGS. 3A and 3B, the receptacle (100) may be positioned against a collapsible frame (20) of the wall (14). The receptacle (100) may be securely attached to at least one of the floor (16), the wall (14) or the collapsible frame (20).

[0200] In an alternative embodiment, the receptacle (100) may be positioned adjacent to a door (12) of a building, as shown in FIG. 4. The receptacle (100) may be secured to the floor (16) of the building in front of the door (12). FIG. 4 shows the receptacle (100) in the contracted configuration where it resembles a door mat. The receptacle (100) is preferably positioned with adequate clearance between the door (12) and the receptacle (100) so as to allow evacuation from the building through the door (12) in case of an emergency such as a fire.

[0201] Aspects of the receptacle (100) should become clearer from the following discussion.

[0202] Referring now to FIGS. 5, 6A, 6B, 6C, 7, 8A, 8B, 9, 10A and 10B which show components of a preferred form of the receptacle (100) according to a form of the technology.

[0203] In general terms, the receptacle (100) includes a housing indicated as (105).

[0204] The housing (105) includes a first end wall (112), a second end wall (113), a first side wall (114), a second side wall (115), a base (117) and a top wall (118).

[0205] A top frame element (119) facilitates attaching components of the housing (105) together. In the present embodiment, the top frame element (119) is a rim-like structure which defines an aperture (119A). The end walls (112, 113), side walls (114, 115), base (117) and the top wall (118) together define a cavity (120) when the receptacle (100) is in the expanded configuration.

[0206] In an alternative embodiment (not shown in the Figures), the top frame element may be a grid-like structure defining multiple apertures which provide access to multiple cavities of the receptacle. Each of these cavities may be compartmentalized and inaccessible through other cavities.

[0207] In the illustrated embodiment, one or more of the top frame element, walls and base (119, 112, 113, 114, 115, 117) are movable to enable the housing (105) to move between the contracted configuration and the expanded configuration.

[0208] The base (117) has relatively shorter edges (117B, 117C) which provide end sides of the base (117), and relatively longer edges (117D, 117E) which provide lateral sides of the base (117).

[0209] The top frame element (119) has relatively shorter edges (119B, 119C) which provide end sides of the top frame element (119), and relatively longer edges (119D, 119E) which provide the lateral sides of the top frame element (119).

[0210] The first side wall (114) is attached to the relatively longer edge (119D) of the top frame element (119) by a hinge (124). The second side wall (115) is attached to relatively longer edge (119E) by a hinge (125). In the embodiment of FIGS. 5, 6A, 6B, 6C, 7, 8A and 8B, the first side wall (114) and the second side wall (115) are not attached directly to the base (117).

[0211] In the illustrated embodiment, each of the hinges (124, 125) are identical to each other and therefore like references refer to like components. The hinges (124, 125) are each a rod hinge, formed by at least one sleeve (124SA, 125SA) provided on the relatively longer edges (119D, 119E) and at least one sleeve (1245B, 1255B) provided at or towards a top edge of the first side wall (114) and a top edge of the second side wall (115). A rod (124R) is disposed in the sleeves (124SA, 1245B) to facilitate rotational movement of the first side wall (114) and the second side wall (115) relative to the top frame element (119). Similarly, a rod (125R) is disposed in the sleeves (125SA, 1255B) to form the hinge (125).

[0212] The sleeves (124SA, 125SA) may be integrally formed with the respective edges (119D, 119E). Similarly, the sleeves (1245B, 1255B) may be integrally formed with the top edge of the first side wall (114) and the top edge of the second side wall (115).

[0213] In an alternative embodiment (not shown in the Figures) the sleeves (124SA, 125SA) may be fastened to the respective edges (119D, 119E). The sleeves (1245B, 1255B) may be fastened to the top edge of the first side wall (114) and the top edge of the second side wall (115) respectively. The means for fastening may include, but are not limited to screws, bolts, etc.

[0214] In alternative embodiments (not shown in the Figures), the hinges (124, 125) may be barrel hinges, spring hinges, etc.

[0215] The first side wall (114) and the second side wall (115) are preferably configured to rotate inwards when the receptacle (100) moves from the expanded configuration to the contracted configuration. This arrangement enables the receptacle (100) to have a compact contracted configuration.

[0216] In a preferred embodiment, the hinges (124, 125) have a restricted range of motion. For instance, the hinges (124, 125) are configured to restrict or prevent the first side wall (114) and the second side wall (115) rotating outwardly beyond a substantially vertical plane. This may assist in securing the receptacle (100) and preventing unauthorized access to any items inside the cavity.

[0217] FIGS. 8A and 8B illustrate a sub-assembly (121) in which the second side wall (115) is attached to the top frame element (119). A similar arrangement is used to attach the first side wall (114) to the top frame element (119) and hence is not illustrated in FIGS. 8A and 8B.

[0218] The receptacle (100) includes at least one biasing component indicated generally as (122) in FIGS. 5 and 8B. The biasing component(s) (122) are configured to urge the first side wall (114) and the second side wall (115) towards, and to preferably lie flat against, the top frame element (119).

[0219] In the illustrated embodiments, the biasing component(s) (122) are each a torsion spring. They could also be a leaf spring or a compression spring.

[0220] In an alternative embodiment (not shown in the Figures), each of the first side wall (114) and the second side wall (115) may be rotated by one or more rotary actuators.

[0221] The use of a/the biasing component(s) (122) is useful to facilitate the receptacle (100) being moved into the contracted configuration. For instance, the biasing component(s) (122) assist in minimizing the height of the receptacle (100) by moving the first side wall (114), the second side wall (115) and top frame element (119) towards an orientation in which they lie flat relative to each other, and preferably holding them in that configuration. In addition, the biasing component(s) (122) may reduce(s) the number of moving components required to move the receptacle (100) from the expanded configuration to the contracted configuration.

[0222] In the illustrated embodiment, the biasing components (122) are configured to bias the first side wall (114) and the second side wall (115) to rotate about the hinges (124, 125) e.g. when the cavity (120) is empty. However, the side walls (115) can rotate downwards when an item is moved through the aperture so that it's the weight of the items acts against the force of the biasing component(s) (122).

[0223] The first end wall (112) is provided by a first end wall plate (112B) and a second end wall plate (112C), and the second end wall (113) is a provided by a first end wall plate (113B) and a second end wall plate (113C).

[0224] The first end wall plate (112B) is attached to the second end wall plate (112C) by a hinge which is indicated generally as 112H. The first end wall plate (113B) is attached to the second end wall plate (113C) by a hinge which is indicated generally by 113H.

[0225] The first end wall plate (112B) is attached to the relatively short edge (119B) of the top frame element (119) by a hinge (126). The second end wall plate (112C) is attached to the relatively short edge (117B) of the base (117) through a hinge (128).

[0226] The first end wall plate (113B) is attached to the relatively short edge (119C) of the top frame element (119) by a hinge (127). The second end wall plate (113C) is attached to the relatively short edge (117C) of the base (117) through a hinge (129).

[0227] Each of the end walls (112, 113) is configured to fold inwardly toward the cavity (120) as the receptacle (100) moves from the expanded configuration to the contracted configuration. In the contracted configuration, the first end wall plate (112B) lies substantially flat against the second end wall plate (112C), while the first end wall plate (113B) lies substantially flat against the second end wall plate (113C).

[0228] The top wall (118) is connected to an edge of the top frame element (119) e.g. by the hinge (126).

[0229] In the illustrated embodiment, the hinge (126) is a rod hinge comprising a sleeve (126S) and a rod (126R). The sleeve (126S) may be integrally formed at a top end of the first end wall plate (113B). In an alternative embodiment (not shown in the Figures), the sleeve (126S) may be fastened to the first end wall plate (113B). The means of fastening may include fasteners such as, but not limited to screws, bolts, etc.

[0230] The top wall (118) provides a closure element for the receptacle (100).

[0231] In embodiments the top wall (118) may have a top layer that helps disguise the receptacle (100) as a mat. e.g. a layer of bristles, rubber mesh, paint or other material. Alternatively, the top wall (118) may be formed from materials which help to ensure that it looks like an upper surface of a door mat. The foregoing description is not to be seen as limiting the invention. Alternative finishes to the top wall (118) or any other component of the receptacle (100) may be provided.

[0232] When the receptacle (100) is disguised as a floor mat or a door mat, a load may be applied on the top wall (118) due to one or more persons standing on the disguised receptacle (100). In the contracted configuration, the receptacle (100) may be configured to transfer the load incident on the top wall (118) to the floor (16) through one or more of the hinges (112H, 113H, 124, 125, 126, 127, 128, 129). Further, the top wall (118) may be made of a material with sufficient structural strength to enable the transfer of the load to the floor (16) without failing.

[0233] In embodiments, the receptacle (100) includes a cover (140) which can be, for example, provided in the form of a skirt (144).

[0234] The skirt (144) provides a weather-resistant exterior that protects items inside the cavity (120) and other components of the receptacle (100) e.g. from water, rain, snow or sunlight. For instance, the skirt (144) assists in preventing ingress of moisture into the cavity (120) through gaps between the walls, at the hinges etc.

[0235] Referring now to FIG. 10A, which shows an exploded view of the cover (140) including the skirt (144) relative to a base frame element (148), the top frame element (119) and the top wall (148). A lower edge (145) of the skirt (144) is attached to the base frame element (148), while a top edge (146) of the skirt (144) is attached to the top frame element (119).

[0236] The base frame element (148) is attached to the base (117) e.g. using screws, welding or adhesive. The base frame element (148) may define a tray into which components of the receptacle (100) can be folded when in the contracted configuration.

[0237] The skirt (144) is configured to rise and fall as the top frame element (119) moves up and down as the receptacle (100) is moved between the expanded configuration and the contracted configuration.

[0238] The receptacle (100) includes at least one guide unit (150) configured to guide the skirt (144) as the receptacle (100) moves between the expanded configuration and the contracted configuration.

[0239] Each guide unit (150) comprises a spring-loaded reel (152) with an elastic cable (154).

[0240] In the embodiment of FIG. 10B, a spring-loaded reel (152) is attached at or towards each corner of the base (117). The elastic cables (154) are attached to corresponding corners of the top frame element (119). Therefore, the elastic cables (154) unwind from the respective spring-loaded reel (152) as the top frame element (119) moves away from the base (117).

[0241] Similarly, the elastic cables (154) are wound back onto their respective spring-loaded reel (152) as the top frame element (119) moves towards the base (117). This arrangement helps to ensure that the skirt (144) may remain within the perimeter of the receptacle (100) in the contracted configuration. In addition, the guide unit (150) can help to prevent the skirt (144) tangling, and therefore facilitate operation of the receptacle (100).

[0242] In the illustrated embodiment, the skirt (144) is formed from a flexible material and/or a stretchable material, e.g. polypropylene or polyethylene. The skirt (144) could be also formed from other materials e.g. a textile material coated with a water-resistant coating like GORTEX™.

Actuators

[0243] In embodiments, the receptacle (100) includes at least one actuator (160) configured to move the receptacle (100) from the contracted configuration to the expanded configuration.

[0244] In the illustrated embodiment, the actuator (160) is in the form of a pen actuator having a rod (163) and a cylinder (164). In use, the rod (163) extends and contracts within the cylinder (164) to move a distal end (163E) of the rod (163) relative to the cylinder (164).

[0245] The pen actuator (162) may have a screw-thread drive powered by a motor e.g. servo motor. The rod (163) may have a screw thread (not illustrated) which mesh a corresponding screw thread (not pictured). In use, rotation of the rod (163) causes the screw threads (not illustrated) to interact to translate rotational motion of the piston to extension and contraction.

[0246] The actuator (160) may also have a detector (shown in FIG. 15) that identifies if the rod (163) of the actuator (160) is extended or withdrawn. The detector may be a hall effect sensor or limit switch.

[0247] In use, expansion and/or contraction of the actuator (160) causes the receptacle (100) to move between the expanded configuration and contracted configuration.

[0248] As illustrated, the actuator (160) includes a linkage (166) comprising a first link arm (167). The first link arm (167) has a first end (167A) and a second end (167B). The first end (167A) of the first link arm (167) is attached to the distal end (163E) by an axle (175). The axle (175) is disposed in a guide (172) provided on the base (117).

[0249] The second end (167B) of the first link arm (167) is rotatably attached to the top frame element (119) by an axle (176).

[0250] An alternate embodiment for the actuator (160) is to replace the axle (176) with rotary actuator. In another alternative embodiment (not illustrated in the Figures), a rotary actuator may be configured to exert force on the axle (176) so as to rotate the axle (176).

[0251] As the actuator (160) expands and contracts, the axle (175) slides along the guide (172) as well as rotating. This causes the first link arm (167) to translate between a position substantially parallel to the base frame element (148) and a position orientated at an angle to the base frame element (148).

[0252] The linkage (166) also includes a second link arm (168) which helps to guide movement of the first link arm (167). The second link arm (168) includes a first end (168A) and a second end (168B), and is rotatably secured to the first link arm (167) by an axle (166X) located between the first end (167A) and the second end (167B).

[0253] The second link arm (168) prevents the first link arm (167) from being pulled horizontally by the actuator (160) in the direction of the actuator's (160) expansion/contraction. The restriction of horizontal motion provided by the second link arm (168) causes the first link arm (167) to translate the contraction of the actuator (160) substantially vertically, thereby moving the top frame element (119) substantially vertically.

[0254] The second end (168B) of the second link arm (168) is attached to the top frame element (119) by an axle (173) which is disposed in a guide (170) provided on the top frame element (119). The first end (168A) of the second link arm (168) is rotatably mounted to the base (117) by an axle (174).

[0255] In use, the axle (173) can slide within the guide (170) and allows the orientation of the second end (168B) relative to the top frame element (119) to change.

[0256] To move the receptacle (100) from the contracted configuration to the expanded configuration, the pen actuator (162) is engaged and contracts, causing the distal end (163E) to move towards the cylinder (164).

[0257] This causes the axle (175), and thereby the first end (167A) of the first link arm (167), to move along the guide (172) towards the cylinder (164). The axle (176) rotates causing the orientation of the first link arm (167) with respect to the base frame element (148) to change and forcing the second end (167B) generally upwards. The second link arm (168) and the first link arm (167) rotate with respect to each other about axle (166X).

[0258] In addition, the axle (173) is moved upwards and generally along the length of the receptacle (100) in the direction of edge (119E), along the guide (170). This forces the second end (168B) generally upwards.

[0259] To move the receptacle (100) from the expanded configuration to the contracted configuration, the above process is reversed. That is, the actuator (160) is engaged to expand, which moves the first link arm (167) towards an orientation in which it is substantially parallel to the bottom frame element (148).

[0260] The receptacle (100) includes a closure actuator, indicated generally as (180), which is configured to move the top wall (118) to thereby open and/or close the receptacle (100).

[0261] In the illustrated embodiment, the closure actuator (180) is a linear actuator, preferably a pen actuator comprising a rod (178) and a cylinder (179). The cylinder (179) is mounted to a hinge (132) which extends from the hinge (113H). Alternatively, the cylinder (179) may be directly mounted to the hinge (113H). The rod (178) has a distal end (178E) which is rotatably connected to the top wall (118) by an axle (182).

[0262] Alternatively, the closure actuator (180) may be a rotary actuator or other suitable actuator mechanism. The rotary actuator may be attached to the hinge (126).

[0263] To open the top wall (118), the closure actuator (180) is engaged to expand which moves distal end (178E) away from cylinder (179). The distal end (178E) rotates about axle (182) and applies force to cause the top wall (118) to rotate about the hinge(s) (126).

[0264] To close the receptacle (100) the process is reversed. That is, the closure actuator (180) is engaged to contract. This moves the distal end (178E) towards the cylinder (179) which applies force to the top wall (118) causing it to rotate about hinge(s) (126) to block the aperture (119A).

Locking Mechanism

[0265] The receptacle in the illustrated embodiment includes a locking mechanism (184) which is configured to prevent unauthorized movement of the top wall (118). Therefore, the locking mechanism assists in preventing unauthorized access into the receptacle (100). FIGS. 13A, 13B and 13C show close up views of the locking mechanism (184).

[0266] The locking mechanism (184) in the illustrated embodiment is a solenoid lock.

[0267] Alternatively, the locking mechanism (184) may be a mechanical lock operated by levers and opened by one or more physical keys.

[0268] In the present embodiment, the locking mechanism (184) includes a bolt element (184B) which is configured to be inserted through a catch or a hook (185). The bolt element (184B) may be attached to the top frame element (119) and the catch or hook (185) may be located on the top wall (118), and vice versa. When the bolt element (184B) engages the catch or hook (185) the locking mechanism (184) is in a locked configuration which prevents the top wall (118) being moved. When the bolt element (184B) does not engage the catch or hook (185) the locking mechanism is in an unlocked configuration and the top wall (118) can be moved.

[0269] The bolt element (184B) may be locked relative to the hinge (127) e.g. by threading the bolt element (184B) to an end (127A) of a rod (127R) of the hinge (127), as shown in FIG. 13C.

[0270] The locking mechanism (184) may be configured to maintain its position with respect to the end wall plate (112B) and the hinge (127) when the receptacle (100) moves between the expanded configuration and the contracted configuration. For instance, a circlip (127C), as shown in FIGS. 13B and 13C attaches to a sleeve (112BS) provided on the end plate (112B) and to the rod (127R).

Control System

[0271] In embodiments, the receptacle includes a control system.

[0272] Referring now to FIGS. 5, 14A and 14B which show the components of the control system and their location in the receptacle (100).

[0273] The control system includes a processing unit (1002) which is in communication with, and configured to control operation of, one or more of the other components of the receptacle e.g. the drive actuator (162) and the closure actuator (180).

[0274] Referring now to FIG. 14A in which the control system includes the processing unit (1002) and a battery pack (1004). The battery pack (1004) allows the receptacle (100) to function as a stand-alone apparatus and dispenses with the need for a tethered power connection. This implies that the receptacle (100) may be placed anywhere without a requirement to be located close to a source of power, such as an electric socket.

[0275] The processing unit (1002) and the battery pack (1004) are typically heavy. Locating heavy components on a moving part of the housing (105) would hinder moving the receptacle to the expanded configuration. Therefore, the processing unit (1002) and/or the battery pack (1004) are preferably placed as close as possible to the floor (16).

[0276] In the embodiment of FIGS. 5, 14A and 14B, the processing unit (1002) and the battery pack (1004) are placed on the base (117), preferably outside the cavity (120).

[0277] The components of the control system are preferably not located inside or under the cavity (120) as it reduces the amount of space available for items to be placed inside the cavity (120). Therefore, at least some components of the control system are located on the edges of the base (117), preferably under the base frame element (148). Therefore, the material of the base frame element (148) preferably has the strength to protect any sensitive components of the control system placed beneath it.

[0278] In embodiments where the contracted configuration is a mat configuration, such as the one in FIGS. 1B and 2A, the base frame element (148) may form a boundary around the top wall (118) when the receptacle (100) is placed in the mat configuration. The base frame element (148) may have an appearance like the top layer on the top wall (118).

[0279] The processing unit (1002) and the battery pack (1004) are usually weather-sensitive. Therefore, as shown in FIG. 14B, the processing unit (1002) and the battery pack (1004) are covered by the base frame element (148) to protect the weather-sensitive components (1002, 1004). Accordingly, it is preferable that the base frame element (148) be made of a weather-resistant material.

[0280] In an embodiment, the control system may be configured to control the actuator(s) (160). The processing unit (1002) transmits instructions to initiate the drive unit (162) to place the housing (105) in an expanded configuration and/or a contracted configuration.

[0281] In an embodiment, the control system may be configured to provide selective access to the cavity (120) by controlling the opening and/or closing of the top wall (118). The processing unit (1002) transmits instructions to the closure actuator (180) to open and/or close the top wall (118). Further, the processing unit (1002) also locks and/or unlocks the top wall (118) by controlling the locking mechanism (184).

Sensors

[0282] In embodiments, the receptacle (100) may include one or more sensors. The sensor(s) are configured to independently or in combination measure different parameters.

[0283] In the illustrated embodiments, the sensor(s) include load cells (1012). The load cells (1012), as shown in FIG. 5, are located below the base (117) on or towards each corner of the base (117). The load cells (1012) are weight sensors which are configured to measure weight of the items inside the cavity (120) and transmit data related to the measured weight to the processing unit (1002).

[0284] In an embodiment (not shown in the Figures), the sensor(s) may include at least one dimension sensor (not shown in the Figures) to measure at least one dimension of each item in the receptacle (100).

First Embodiment of a Circuit

[0285] Referring now to FIG. 15 which shows a block representation of a circuit (1025) which connects the control system to the sensor(s) and components of the actuator(s) (160) according to the embodiment of FIG. 5.

[0286] The circuit (1025) connects the processing unit (1002), the battery pack (1004), the locking mechanism (184), the closure actuator (180), the drive unit (162) and the one or more sensors. The circuit (1025) facilitates transmission of information from the processing unit (1002) and the other components on the circuit (1025). The circuit (1025) also facilitates transmission of feedback from the other components on the circuit (1025) to the processing unit (1002). The battery pack (1004) is connected to the processing unit (1002) to transmit power.

[0287] The circuit (1025) may also include a closure actuator limit switch (1027) which detects if the closure actuator (180) is extended or collapsed. The closure actuator limit switch (1027) helps to ensures that motor drives of the closure actuator (180) do not overextend or over compress the closure actuator (180). This may reduce or prevent undue stress on transmission components of the closure actuator (180) and its motor. The closure actuator limit switch (1027) also ensures a level of redundancy.

Second Embodiment of the Circuit

[0288] Referring now to FIG. 16 which shows a block representation of a circuit (2025) which connects the control system, the sensor(s) and the communication system.

[0289] The circuit (2025) connects the processing unit (1002), the load cell(s) (1012), a memory storage device (2048), a Bluetooth module (2044) which includes, a receiver and a transmitter.

[0290] For instance, the Bluetooth module may be a BTLE module, which is a low energy module. Alternative Bluetooth modules or components may also be used.

[0291] In the embodiment illustrated in FIG. 16, the delivery entity (10) communicates with the receptacle (100) through a device having a circuit (3060). The circuit (3060) connects a processing unit (3002), a memory storage device (3048), a Bluetooth module (3044), an internet receiver (3042) and a GPS module (3062). The Bluetooth module (2044) is configured to include a receiver and a transmitter.

[0292] The memory storage device (3048) includes information related to a delivery route to the receptacle (100). The GPS module (3062) provides GPS data to guide the delivery service (10) along the delivery route stored in the memory storage device (3048).

[0293] When the delivery service (10) comes within range of the Bluetooth module (2044), the Bluetooth module (3044) establishes connection with the Bluetooth module (2044). The transmitter (3050) sends one or more of a wakeup signal, a user ID signal and delivery data to the receiver in the Bluetooth module (2044) which relays the received data to the processing unit (1002). The processing unit (1002) matches the received data against corresponding data stored in the memory storage device (2048).

[0294] On confirming that the delivery service (10) is authorized, the receptacle (100) is opened to allow access to the cavity (120). After an item is delivered and/or picked up from the receptacle (100), the load cell(s) (1012) measure weight difference and relays the same to the processing unit (1002). The processing unit (1002) matches the weight difference against weight value of the item stored in the memory storage device (2048).

[0295] The respective weight values of the items may be transmitted to the memory storage device (2048) through the Bluetooth module (2044). Data of the weight values may be transmitted in discrete data packet or continuously.

[0296] Alternatively (not shown in the Figure), the communication system may include a wire-tethered receiver which may be connected to an input device. The respective weight values of the items may be entered into the memory storage device (2048) through the input device.

[0297] On confirming that the correct item is delivered to and/or picked up from the receptacle (100), the transmitter in the Bluetooth module (2044) sends information to the receiver (3046) confirming successful delivery and/or pick-up.

[0298] The receiver (3046) relays the information to the processing unit (3002) which initiates the internet receiver (3042). On connecting a delivery unit of the delivery service (10) to the internet, the transmitter (3050) sends confirmation of successful delivery and/or pick-up to a recipient and/or a sender respectively.

[0299] If the delivery and/or pick-up is unsuccessful, the transmitter (3050) is configured to send information of the failed delivery and/or pick-up to the recipient and/or the sender respectively.

Method

[0300] Referring now to FIG. 17A to 17E which shows the steps of the receptacle (100) moving from the contracted configuration and the expanded configuration.

[0301] The receptacle (100), when not in use, is in the contracted configuration. If one or more items are to be delivered to and/or sent from the receptacle (100), the receptacle (100) is placed in the expanded configuration.

[0302] The receptacle (100), on being triggered to be placed from the contracted configuration to the expanded configuration, initiates the actuator (160). The actuator (160) contracts to move the top frame element (119) upwardly. The hinged plates (112B, 112C, 113B, 113C) of each end wall (112, 113) begin to unfold as the top frame element (119) rises upward. The elastic cables (154) unwind and the skirt (not shown in FIG. 16) begins to rise. This stage is shown in FIG. 17B.

[0303] As the top frame element (119) moves further upward, the elastic cables (154) unwinds further and the hinged plates (112B, 112C, 113B, 113C) of the end walls (112, 113) further unfold. This stage is shown in FIG. 17C.

[0304] In the stage shown by FIG. 17D, the plates (112B, 112C, 113B, 113C) of the end walls (112, 113) align in a substantially straight line. The actuator (160) stops contracting and therefore the top frame element (119) stops moving. The control system unlocks the top wall (118).

[0305] In an alternative embodiment, the control system may ascertain that the delivery service (10) seeking access to the receptacle (100) is authorized to do so. Only if the delivery service (10) is authorized, the control system will initiate the receptacle (100) to be placed in an expanded configuration and/or unlock the top wall (118).

[0306] As illustrated in FIG. 17E, the cavity (120) is formed when an item is placed inside the receptacle (100). The side walls (114, 115) are forced down by the weight of the object or item counterweighing the biasing components (122).

[0307] The control system is configured to lock the receptacle (100) after confirming that the delivery is successfully made.

[0308] Once the item(s) which are secured by the receptacle are removed, the receptacle (100) goes through stages 16E, 16D, 16C, 16B and 16A, in the mentioned order to revert to the contracted configuration.

[0309] Referring now to FIG. 18 which shows representative steps in a method of delivering items according to an aspect of the technology.

[0310] At step A, a receptacle (100) as substantially described herein is positioned in a delivery location e.g. offset from the front of a door (12) beside or attached to a building. The receptacle (100) is in the contracted configuration as shown in FIGS. 1B, 2A, 2C, 3B and 17A e.g. at least one dimensions is relatively reduced compared to when the receptacle is in the expanded configuration.

[0311] At step B a delivery signal is transmitted to the receptacle (100) and received by the communication system.

[0312] At step C, the processing unit (1002) is configured to check details of the delivery signal to determine whether the receptacle (100) is to receive an item to be delivered. If the delivery signal is approved, then the processing unit (1002) engages the actuator (160) to contract and move the receptacle (100) from the contracted configuration to the expanded configuration.

[0313] The above step allows the receptacle (100) to be in the expanded configuration when a delivery service (10) arrives at the delivery location. According, this may reduce delivery times by removing the need for the receptacle (100) to be configured only after the delivery service (10) arrives.

[0314] If the delivery signal is not approved, the processing unit (1002) may: [0315] send a signal indicating that the delivery is not to be received; [0316] take no action; [0317] engage the actuator (160) to move the receptacle (100) to the expanded configuration notwithstanding that an access code is incorrect. At step D the delivery service (10) sends a signal to the receptacle (100) which is received by the communication system. The processing unit (1002) is configured to engage the closure actuator (180) to move the top wall (118) relative to the top frame element (119) and thereby to allow access into the cavity (120).

[0318] At step E, the delivery service (10) places the item(s) in the cavity (120). The load cells (1012) measure the weight difference of the receptacle (100) due to weight of the delivered items and relay this data to the processing unit (1002). The processing unit (1002) matches the weight difference measured by the load cells (1012) against values of weight corresponding to each of the items. The weight values may be stored in the memory storage device (2048).

[0319] At step F, the processing unit (1002) initiates the closure actuator (180) to close the top wall (118). Next, the closure mechanism (184) is triggered to lock the top wall (118).

[0320] The following steps follow step F based on the weight difference measured by the load cells (1012) and instructions provided by the recipient and/or the sender: [0321] If the weight difference measured by the load cells (1012) is 0, then step G is initiated; [0322] If the weight difference measured by the load cells (1012) is not equal to the stored weight values of each of the items to be delivered, then step H is initiated; and [0323] If the weight difference measured by the load cells (1012) is within a specific tolerance, e.g. 5% of the stored weight values of the item(s) to be delivered, then step I is initiated.

[0324] In step G, the processing unit (1002) initiates the actuators (160) to place the receptacle (100) in the contracted arrangement. The processing unit (1002) also instructs the communication system to send a message indicating that no item was delivered. to the recipient.

[0325] In step H, the processing unit (1002) instructs the communication system to send a message indicating wrong delivery to the recipient and/or the delivery service (10). Further, the receptacle (100) may be configured to allow the delivery service (10) to access the cavity (120) to replace the wrong item with the item. The receptacle (100) may require the delivery service (10) to resupply credentials before allowing access to the cavity (120).

[0326] In step I, the processing unit (1002) instructs the communication system to send a message indicating successful delivery to the recipient and/or the delivery service (10).

[0327] Alternatively, or in addition to sending a message, information of no delivery, wrong delivery and/or successful delivery, may be uploaded to an external cloud or to the memory storage device (2048). This ensures that proof of no delivery, a missed delivery and/or successful delivery remains recorded even if the recipient loses the message sent by the communication system.
