DETAILED DESCRIPTION
Embodiments of the present invention relate generally to a locker bay system. Specifically, in some embodiments a locker bay includes a catch loop coupled to a locker door and a locking mechanism that releaseably secures the catch loop to lock and unlock the locker bay. In particular, the locking mechanism includes a lock bar that pulls and pushes the catch loop in and out of the lock bar to lock and unlock the locker bay.
In the embodiments shown in FIGS. 1-3, a locker module 100 includes ten locker bays 102 of various sizes and shapes. In other embodiments, the locker module 100 may include only one locker bay 102 or may include more than one or more than ten locker bays 102. Multiple locker modules 100 may be coupled together to form a locker array. The locker bays, locker modules, and/or locker arrays may include electronic and/or mechanical user interfaces. The locker bays, locker modules, and/or locker arrays may also include wired and/or wireless communication equipment to interface with remote devices (e.g., central control systems) and/or users (e.g., user mobile phones or laptops) as well as local devices (e.g., a local central control system, or other local locker bays, locker modules, or locker arrays).
The locker bay 102 includes a locker door 104 that permits access to the interior 106 of the locker bay 102. The locker door 104 includes one or more hinges 108 pivotally coupling the locker door 104 to the locker bay 102. In some embodiments, the locker door 104 is spring biased towards a closed position. In some embodiments, the locker door 104 is spring biased towards an open position. The locker door 104 also includes a catch loop 110 coupled to an interior surface 112 of the locker door 104. The locker bay 102 includes a locking mechanism 114 that receives the catch loop 110 to secure the locker door 104 in the closed position. In some embodiments, the locker door 104 includes a lip (not shown) to enable users to open the locker door 104. When the locker door 104 is in the closed position, the lip may be flush with the locker bay 102 (e.g., center bar 115 in FIG. 1) to prevent unauthorized access to the interior 106 of the locker bay 102. As shown in FIG. 3, the locking mechanism 114 includes an exterior surface 120 that has an exterior surface aperture 122 to receive the catch loop 110.
The locking mechanism uses a lock bar 130, as shown in isolation in FIG. 4. The lock bar 130 includes a first aperture 132 and a second aperture 134. In the embodiment shown in FIG. 4, these apertures 132, 134 and form closed loops and are linearly aligned (e.g., a major axis 133 of the first aperture 132 substantially aligns with a major axis 135 of the second aperture 134). As described below in more detail, these apertures 132, 134 receive modified washers that limit the lock bar's vertical movement and prevent the lock bar 130 from moving horizontally and laterally. The lock bar 130 also includes a cam shaft aperture 136 that receives a cam shaft (178 in FIGS. 6-8) responsible for vertically sliding the lock bar 130. In some embodiments, a major axis 137 of the cam shaft aperture 136 is substantially perpendicular to the major axis 133 of the first aperture 132 and the major axis 135 of the second aperture 134.
In addition, the lock bar 130 includes a catch loop opening 138. The catch loop opening 138 includes a first section 140 connecting to a second section 142. The first section 140 of the catch loop opening 138 is bound by a first section lower surface 144 and a first section upper surface 146. The second section 142 of the catch loop opening is bound by a second section exterior side surface 148, a second section interior side surface 150, and a second section upper surface 152. In the embodiment shown in FIG. 4, the first section lower surface 144 and the second section interior side surface 150 form an angle 154 of approximately 135 degrees, as measured in a direction passing through the catch loop opening 138. The first section upper surface 146 and the second section exterior side surface 148 form an angle 156 of approximately 225 degrees, as measured in a direction passing through the catch loop opening 138. In other embodiments, the angles 154, 156 vary +/−45 degrees. As described below in more detail, the angles 154, 156 enable the lock bar 130 to push and pull the catch loop 110 out and in of the catch loop opening 138 as the lock bar 130 moves to and from the locked and unlocked positions, respectively.
FIG. 5 illustrates a modified washer 160. The modified washer 160 includes an upper section 162 and a lower section 164. The lower section 162 has a diameter 166 that is sized to fit within the first aperture 132 or the second aperture 134 of the lock bar 130 to prevent lateral movement. The upper section 164 has a diameter 168 that is sized so that a lower surface 170 of the upper section 164 contacts or resides over the lock bar 130 when the lower section 162 is placed within the first aperture 132 or the second aperture 134 of the lock bar 130 to prevent or limit horizontal movement of the lock bar 130. The modified washer 160 includes a central bore 172 located along a central axis 174 of the modified washer 160. The central bore 172 is sized to receive a bolt or pin to secure the modified washer 160 to the locking mechanism 114, as shown in subsequent figures.
FIGS. 6-8 illustrate the lock bar 130, a first modified washer 160 and a second modified washer 176 (a third modified washer 177, shown in FIG. 11, may also be used in conjunction with the cam shaft 178), as well as additional components of the locking mechanism 114. The first modified washer extends into the first aperture 132 of the lock bar 130 and the second modified washer 176 extends into the second aperture 134 of the lock bar 130. A cam shaft 178 is coupled to a cam wheel 180 and extends into the cam shaft aperture 136 of the lock bar 130. The locking mechanism 114 also includes an upper sensor 182 and a lower sensor 184 that detect the lock bar 130 when it is in an upper location and a lower position, respectively. The locking mechanism 114 further includes a catch loop sensor 186 that detects the catch loop 110 when the locking mechanism is in a locked configuration.
FIGS. 6-8 also illustrate the locking mechanism 114 as it moves from a locked position (FIG. 6) to an unlocked position (FIG. 8). In FIG. 6, the cam wheel is in a “locked” position in which the cam shaft 178 is in a “6:00” position. In FIG. 7, the cam wheel 180 has rotated (e.g., due to an electric motor 188 as shown in FIG. 9) from that locked position into a “partially locked” position in which the cam shaft 178 is in a “9:00” position. By rotating the cam wheel 180, the cam shaft 178 forces the lock bar 130 upward as the modified washers 160, 162 prevent the lock bar 130 from moving horizontally or laterally. As the lock bar 130 moves upward, the catch loop 110 exits the second section 142 of the catch loop opening 138 and enters the first section 140 of the catch loop opening 138. As the lock bar 130 continues upward, the first section lower surface 144 forces the catch loop outwards. In FIG. 8, the cam wheel 180 has rotated into an “unlocked” position in which the cam shaft 178 is in the “12:00” position. With that movement, the lock bar 130 reaches its highest point and the first section lower surface 144 has pushed the catch loop 110 out of the catch loop opening 138. The locker door 104 may be opened to permit access to the locker bay 102.
In some embodiments, the locker door 104 includes a spring (e.g., as part of the hinge or hinges 108) that forces the locker door 104 towards the closed position. In those embodiments, the catch loop 110 will push against the outer surface of the lock bar 130 (e.g., just below the catch loop opening 138) or against a lower portion of the first section lower surface 144 of the catch loop opening 138 when the locking mechanism is in the unlocked position. To transition from the unlocked position (FIG. 8) to the locked position (FIG. 6), the cam wheel 180 continues to rotate clockwise. In other embodiments, the cam wheel 180 begins a counter-clockwise rotation. With rotation in either direction, the cam shaft 178 causes the lock bar 130 to slide down, such that the first section upper surface 146 of the catch loop opening 138 pulls the catch loop 110 deeper into the catch loop aperture 138. In those embodiments in which the locker door 104 includes a spring, the forces exerted by the spring on the door push the catch loop 110 deeper into the catch loop opening 138. Further rotation by the cam wheel 180 continues this motion until the cam wheel 180 returns to the “locked” position in which the cam shaft 178 is in the “6:00” position and the catch loop 110 is secured within the second section 142 of the catch loop opening 138.
In some embodiments, the dimensions of the lock bar 130 or catch loop opening 138 are selected to prevent injury, damage, or unauthorized entry into the locker bay 102 as the locking mechanism 114 secures the locker door 104. For example, the distance from the second section exterior side surface 148 of the catch loop opening 138 to an exterior surface (151 in FIG. 4) of the lock bar 130 may be substantially equal to or less than the thickness (113 in FIG. 2) of the locker door 104. In those embodiments, the inner surface 112 of the locker door will be adjacent to or flush with the locker bay 102 (e.g., the center bar 115 in FIG. 1). This eliminates a gap between the locker door 104 and the locker bay 102 before the electric motor (188 in FIG. 9) engages the lock bar 130, so that fingers or other objects are not left between the locker door 104 and the locker bay 102 as the motor 188 pulls the locker door 104 into the closed position.
FIG. 9 depicts the locking mechanism 114 with additional components, such as an electric motor 188 that drives the cam wheel 180 and pins 190, 192 that secure the first and second modified washers 160, 176, respectively. The locking mechanism 114 further includes a processor (not shown) that operates the electric motor 188 by executing instructions stored on a memory. The locking mechanism 114 may include components enabling wired or wireless communications with an external controller or with other locking mechanisms. In some embodiments, the locking mechanism may receive instructions from a local controller, while in other embodiments the locking mechanism may be controlled from a remote server.
In some embodiments, and as shown in FIG. 9, the locker bay 102 includes an object identifier 194. The object identifier 194 could include, for example, an RFID reader, a bar code reader, a camera, and/or other Near-Field Communications technologies. When an object is placed into the locker bay 102, the object identifier 194 interacts with the object (e.g., activates an RFID field to read an RFID tag, scans the object to read an attached barcode, takes a picture, and/or the like) to derive identifying information regarding the object. That identifying information may then be conveyed to external systems (e.g., a local control center or a remote server) for analysis or for further use. For example, the object may be a product incorporating an RFID chip into its packaging. The object identifier 194 uses its RFID reader to read identifying information from the product's RFID chip. The object identifier 194 may then transmit the identifying information to a central server.
Identifying objects placed within the locker bay 102 may be useful in many situations. For example, the locker bay 102 may be part of a vending module and the identifying information read from the product in the locker bay 102 may be used to verify the nature of the offered product or may be used to determine the price of the object in the locker bay 102. In some embodiments, the identifying information may be used to inventory the contents of the locker bay 102, determine the identity of new contents, and/or verify the identity of the contents prior to unlocking or dispensing the product. In another example, a delivery package may be placed into the locking module. The object identifier 194 interacts with the delivery package, for example, by reading a bar code placed on the outside of the package, and conveys the read bar code data to a central server. The central server checks the bar code data against a central database to confirm correct delivery or to record the delivered location. The central server may then transmit instructions to the locking mechanism 114 to secure the locker bay 102 and may also transmit a message to the intended recipient. The recipient then goes to the locker bay 102 and unlocks the locker bay 102, for example by presenting authorizing credentials at a local interface or by authorizing the central server to unlock the locker bay 102.
In some embodiments, the locker bay 102 operates as part of the system described in U.S. Provisional Patent Application No. 61/708,913, entitled Systems and Methods for Locking and Docking, filed on Oct. 2, 2012, which is hereby incorporated by reference in its entirety, or the locker bay 102 operates as part of the system described in U.S. patent application Ser. No. 14/044,714, entitled Systems and Methods for Locking and Docking, filed on Oct. 2, 2013, which is hereby incorporated by reference in its entirety. For example, the locking module 114 could operate as one or more Daughter Boards, Lock Control Boards, or Primary Lock Control Boards as described in that application. In addition, in some embodiments, the catch loop sensor 186 may operate as a Daughter Board (e.g., an ID Daughter Board) and incorporate an RFID reader as described in that application. As further examples, the lock module 100 of the present invention may incorporate Daughter Boards, such as the Sensory Daughter Boards described in that application, and the locking module 114 and the lock bar 130 may be adapted to secure a latching body as described in that application.
Various modifications and additions can be made to the exemplary embodiments discussed without departing from the scope of the present invention. For example, while the embodiments described above refer to particular features, the scope of this invention also includes embodiments having different combinations of features and embodiments that do not include all of the above described features.
