The subject matter discussed herein relates generally to locking apparatus and methods for locking the hinged or removable lids of commercial or large size trash containers or bins/dumpsters by means of a pivoted, lockable bar extending over the lid in the closed position.
Many trash container locking systems are known in which a bar is attached to pivot arms on opposite sides of a trash container for movement between an unlocked position across the front of the container in which the lid can be freely opened and closed, and a locked position extending over the top of the closed lid so it cannot be opened. A locking mechanism is provided to lock one of the arms in place when the bar extends across the top of the lid. Such systems are described, for example, in U.S. Pat. No. 5,029,724 of Serio, U.S. Pat. No. 5,213,382 of Dawdy, and U.S. Pat. Nos. 6,733,053 and 8,313,126 of Hodge Products, Inc. A lid locking system sold by HPI (Hodge Products, Inc.) comprises two pivot arms pivotally mounted on base plates for securing to opposite sides of the trash container, and a separate lock plate to be mounted on one side of the container so that an opening in the pivot arm on that side is aligned with a hole in the lock plate or hasp in the locked position of the bar. Installation and proper alignment of the parts of this system may be difficult in some cases.
According to one aspect, a lid locking apparatus for a trash container comprises first and second pivot devices each having a mounting plate configured to be secured to a respective side edge of the trash container close to the front of the container and respective first and second pivot arms each having a first end pivotally mounted to the respective first and mounting plate and a second end adapted for connection to a respective end of an elongate pipe or bar which is longer than the front end of the trash container. The first pivot device is lockable and the first pivot arm has opposite side edges and an outwardly projecting locking flange on one side edge which has at least one slot or opening. The mounting plate of the first pivot device has a stop plate or padlock hasp extending outwardly from a side edge of the base plate in the same direction as the locking flange. The stop plate also has at least one slot or opening. When the mounting plates are secured by welding, bolting, or the like to opposite sides of a trash container and a bar is secured between second ends of the pivot arms, the arms are rotatable between an unlocked position in which the bar extends across the front of the container and the hinged container lid can be freely opened and closed, and a locked position in which the bar and arms are pivoted upward and rearward so that the bar extends over the top of the container lid. The stop plate on the mounting plate and locking flange on the first pivot arm are positioned and oriented such that the locking flange is adjacent to the stop plate in the locking position with at least part of the opening in the locking flange aligned with an opening in the stop plate. A padlock shackle is engaged through the aligned openings to secure the bar in the locked position, preventing unauthorized dumping of trash in the container.
In one embodiment, the openings in the locking flange and stop plate each comprise an elongated slot for ease in alignment, but in alternative embodiments one of these parts may have a single circular opening or more than one circular opening while the other has an elongated slot. In one embodiment, the locking flange is positioned such that it is in face-to-face engagement with the stop plate in the locking position. In some embodiments, an indent is provided on one edge of the stop plate to act as a welding or attachment point for the chain of a padlock, so that the padlock can be permanently attached to the lockable pivot device and ready for engagement with the aligned openings or slots in the locking flange and stop plate to lock these parts together and prevent access to the container.

Additional processors may be provided, such as an auxiliary processor to manage input/output, an auxiliary processor to perform floating point mathematical operations, a special-purpose microprocessor having an architecture suitable for fast execution of signal processing algorithms (e.g., digital signal processor), a slave processor subordinate to the main processing system (e.g., back-end processor), an additional microprocessor or controller for dual or multiple processor systems, or a coprocessor. Such auxiliary processors may be discrete processors or may be integrated with the processor 560.
The processor 560 is preferably connected to a communication bus 555. The communication bus 555 may include a data channel for facilitating information transfer between storage and other peripheral components of the system 550. The communication bus 555 further may provide a set of signals used for communication with the processor 560, including a data bus, address bus, and control bus (not shown). The communication bus 555 may comprise any standard or non-standard bus architecture such as, for example, bus architectures compliant with industry standard architecture (“ISA”), extended industry standard architecture (“EISA”), Micro Channel Architecture (“MCA”), peripheral component interconnect (“PCI”) local bus, or standards promulgated by the Institute of Electrical and Electronics Engineers (“IEEE”) including IEEE 488 general-purpose interface bus (“GPIB”), IEEE 696/S-100, and the like.
System 550 preferably includes a main memory 565 and may also include a secondary memory 570. The main memory 565 provides storage of instructions and data for programs executing on the processor 560. The main memory 565 is typically semiconductor-based memory such as dynamic random access memory (“DRAM”) and/or static random access memory (“SRAM”). Other semiconductor-based memory types include, for example, synchronous dynamic random access memory (“SDRAM”), Rambus dynamic random access memory (“RDRAM”), ferroelectric random access memory (“FRAM”), and the like, including read only memory (“ROM”).
The secondary memory 570 may optionally include an internal memory 575 and/or a removable medium 580, for example a floppy disk drive, a magnetic tape drive, a compact disc (“CD”) drive, a digital versatile disc (“DVD”) drive, etc. The removable medium 580 is read from and/or written to in a well-known manner. Removable storage medium 580 may be, for example, a floppy disk, magnetic tape, CD, DVD, SD card, etc.

System 550 may also include an input/output (“I/O”) interface 585. The I/O interface 585 facilitates input from and output to external devices. For example the I/O interface 585 may receive input from a keyboard or mouse and may provide output to a display 587. The I/O interface 585 is capable of facilitating input from and output to various alternative types of human interface and machine interface devices alike.
System 550 may also include a communication interface 590. The communication interface 590 allows software and data to be transferred between system 550 and external devices (e.g. printers), networks, or information sources.

Software and data transferred via communication interface 590 are generally in the form of electrical communication signals 605. These signals 605 are preferably provided to communication interface 590 via a communication channel 600. In one embodiment, the communication channel 600 may be a wired or wireless network, or any variety of other communication links. Communication channel 600 carries signals 605 and can be implemented using a variety of wired or wireless communication means including wire or cable, fiber optics, conventional phone line, cellular phone link, wireless data communication link, radio frequency (“RF”) link, or infrared link, just to name a few.
Computer executable code (i.e., computer programs or software) is stored in the main memory 565 and/or the secondary memory 570. Computer programs can also be received via communication interface 590 and stored in the main memory 565 and/or the secondary memory 570. Such computer programs, when executed, enable the system 550 to perform the various functions of the present invention as previously described.
In this description, the term “computer readable medium” is used to refer to any non-transitory computer readable storage media used to provide computer executable code (e.g., software and computer programs) to the system 550. Examples of these media include main memory 565, secondary memory 570 (including internal memory 575, removable medium 580, and external storage medium 595), and any peripheral device communicatively coupled with communication interface 590 (including a network information server or other network device). These non-transitory computer readable mediums are means for providing executable code, programming instructions, and software to the system 550.
In an embodiment that is implemented using software, the software may be stored on a computer readable medium and loaded into the system 550 by way of removable medium 580, I/O interface 585, or communication interface 590. In such an embodiment, the software is loaded into the system 550 in the form of electrical communication signals 605. The software, when executed by the processor 560, preferably causes the processor 560 to perform the inventive features and functions previously described herein.
The system 550 also includes optional wireless communication components that facilitate wireless communication over a voice and over a data network. The wireless communication components comprise an antenna system 610, a radio system 615 and a baseband system 620. In the system 550, radio frequency (“RF”) signals are transmitted and received over the air by the antenna system 610 under the management of the radio system 615.
In one embodiment, the antenna system 610 may comprise one or more antennae and one or more multiplexors (not shown) that perform a switching function to provide the antenna system 610 with transmit and receive signal paths. In the receive path, received RF signals can be coupled from a multiplexor to a low noise amplifier (not shown) that amplifies the received RF signal and sends the amplified signal to the radio system 615.
In alternative embodiments, the radio system 615 may comprise one or more radios that are configured to communicate over various frequencies. In one embodiment, the radio system 615 may combine a demodulator (not shown) and modulator (not shown) in one integrated circuit (“IC”). The demodulator and modulator can also be separate components. In the incoming path, the demodulator strips away the RF carrier signal leaving a baseband receive audio signal, which is sent from the radio system 615 to the baseband system 620.
If the received signal contains audio information, then baseband system 620 decodes the signal and converts it to an analog signal. Then the signal is amplified and sent to a speaker. The baseband system 620 also receives analog audio signals from a microphone. These analog audio signals are converted to digital signals and encoded by the baseband system 620. The baseband system 620 also codes the digital signals for transmission and generates a baseband transmit audio signal that is routed to the modulator portion of the radio system 615. The modulator mixes the baseband transmit audio signal with an RF carrier signal generating an RF transmit signal that is routed to the antenna system and may pass through a power amplifier (not shown). The power amplifier amplifies the RF transmit signal and routes it to the antenna system 610 where the signal is switched to the antenna port for transmission.
The baseband system 620 is also communicatively coupled with the processor 560. The central processing unit 560 has access to data storage areas 565 and 570. The central processing unit 560 is preferably configured to execute instructions (i.e., computer programs or software) that can be stored in the memory 565 or the secondary memory 570. Computer programs can also be received from the baseband processor 610 and stored in the data storage area 565 or in secondary memory 570, or executed upon receipt. Such computer programs, when executed, enable the system 550 to perform the various functions of the present invention as previously described. For example, data storage areas 565 may include various software modules (not shown) that are executable by processor 560.
Various embodiments may also be implemented primarily in hardware using, for example, components such as application specific integrated circuits (“ASICs”), or field programmable gate arrays (“FPGAs”).
