Patent number: 10899570Abstract: Systems, devices and methods for receiving an item in a receptacle are disclosed. Features are disclosed for receiving and guiding an item in a receiving space of a receptacle so as to attenuate or remove the impact force of the item on the receptacle. Some embodiments of the disclosure include a bumper having an impact surface which absorbs most or all of the impact force of the item and thereby mitigates or removes the imposition of cyclic impact loads on the receptacle from repeated receipt of items. The bumper may be structurally and/or functionally de-coupled or otherwise physically separated from the receptacle such that an advantageous division of labor is created between absorbing the impact and receiving the item. This disclosure may be useful, for example, in modern industrial operations where a high volume of items are received daily, such as in mail sorting and handling operations.Type: GrantFiled: April 29, 2019Date of Patent: January 26, 2021Assignee: United States Postal ServiceInventors: Dongliang Yang, James E.
