Modular accessory

摘要

An accessory is provided that includes power supply module, a first functional module, and a second functional module. The power supply module can be configured to be suspended beneath an overhead support, such as a hub of an umbrella. The first functional module is configured to affix to the power supply module and to be powered by the power supply module to provide a user directed function. The second functional module is configured to be detachably coupled to either the power supply module or the first functional module to receive power from the power supply module directly or through the first functional module.

1. A modular accessory for mounting beneath a canopy of a cantilevered umbrella, the modular accessory comprising:
a connection hub comprising an upper portion, a lower portion, and a threaded protrusion projecting away from the lower portion, the upper portion of the connection hub being configured to connect to or forming a portion of a lower hub of a cantilevered umbrella; a power supply module comprising a power supply housing having a lower side and an upper side, a threaded recess projecting from the upper side of the power supply housing toward the lower side of the power supply housing, and a socket located at the lower side of the power supply housing, the socket comprising one or more contacts to transfer power, the power supply housing enclosing a portable power supply or receiving power from an exterior source; a plurality of functional modules, each functional module comprising a module housing having an upper side and a lower side, a socket located at the lower side of the module housing and having an electrical contact disposed therein, and a plug located at the upper side of the module housing; and at least two arrangements wherein the connection hub, power supply module, and at least two functional modules form a unitary structure, wherein, in a first arrangement:
the threaded protrusion of the connection hub is positioned in the threaded recess of the power supply housing to detachably connect the power supply housing to the connection hub;the plug of a first functional module housing is positioned in the socket of the power supply housing to detachably and directly connect the module housing of the first functional module to the power supply housing, the first functional module receiving power from the power supply module; andthe plug of a second functional module housing is positioned in the socket of the first functional module housing to detachably and directly connect the module housing of the second functional module to the module housing of the first functional module, the second functional module receiving power through the contact disposed in the socket of the first functional module housing, and wherein, in a second arrangement:
the threaded protrusion of the connection hub is positioned in the threaded recess of the power supply housing to detachably connect the power supply housing to the connection hub;the plug of the second functional module housing is positioned in the socket of the power supply housing to detachably and directly connect the module housing of the second functional module to the power supply housing, the second functional module receiving power from the power supply module; andthe plug of the first functional module housing is positioned in the socket of the second functional module housing to detachably and directly connect the module housing of the first functional module to the module housing of the second functional module, the first functional module receiving power through the contact disposed in the socket of the second functional module housing.
