Abstract

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.

Claims

1. A modular electronic accessory for a shade structure, the modular electronic accessory comprising:

a connection hub being configured to affix to or forming a portion of a shade structure;

a first functional module comprising upper and lower sides;

a second functional module comprising upper and lower sides,

wherein each of the upper sides of the first and second functional modules comprises a connector for connecting to the connection hub or another functional module; and

at least two arrangements forming a stacked structure comprising at least the connection hub, the first functional module, and the second functional module,

wherein a first arrangement comprises the first functional module electrically connected to and detachably coupled to the second functional module, the lower side of the second functional module being adjacent to and above the upper side of the first functional module, and

wherein a second arrangement comprises the second functional module electrically connected to and detachably coupled to the first functional module, the lower side of the first functional module being adjacent to and above the upper side of the second functional module.

2. The modular electronic accessory of claim 1, wherein the first functional module further comprises a power supply that supplies electrical power to the second functional module.

3. The modular electronic accessory of claim 1, wherein the connectors of the first and second functional modules each comprise at least one electrical contact.

4. The modular electronic accessory of claim 1, wherein the stacked structure comprises a columnar structure.

5. The modular electronic accessory of claim 1, wherein the stacked structure comprises longitudinal axes of the first and second functional modules being in collinear alignment.

6. The modular electronic accessory of claim 1, wherein at least one of the first and second functional modules comprises a side wall having a socket disposed therein, the socket comprising at least one electrical contact.

7. The modular electronic accessory of claim 1, wherein the functional modules comprise modules selected from the following group:

a light module, a power module, and an audio module.

8. An electronic accessory for a shade structure, the electronic accessory comprising:

a power supply unit configured to be supported beneath a component of a shade structure;

a first functional unit that utilizes electrical power from the power supply unit to perform a first function;

a second functional unit that utilizes electrical power from the power supply unit to perform a second function;

a first arrangement forming a unitary structure wherein the first functional unit is connected to and positioned below the power supply unit and the second functional unit is connected to and positioned below the first functional unit, and wherein the power supply unit supplies electrical power directly to the first functional unit and indirectly through the first functional unit to the second functional unit; and

a second arrangement forming a unitary structure wherein the second functional unit is connected to and positioned below the power supply unit and the first functional unit is connected to and positioned below the second functional unit, and wherein the power supply unit supplies electrical power directly to the second functional unit and indirectly through the second functional unit to the first functional unit.

9. The electronic accessory of claim 8, wherein the component of the shade structure comprises at least a portion of a lower hub of a cantilevered umbrella.

10. The electronic accessory of claim 8, wherein, when the power supply unit is suspended beneath the component of the shade structure in the first arrangement, the power supply unit supports the first functional unit, and the first functional unit supports the second functional unit.

11. The electronic accessory of claim 10, wherein, in the first arrangement, the second functional unit is attached to the first functional unit by a connector that both supports the second functional unit and supplies electrical power to the second functional unit.

12. The electronic accessory of claim 8, wherein the power supply unit comprises a battery compartment for insertion therein of at least one battery.

13. The electronic accessory of claim 8, wherein the shade structure comprises a cantilevered umbrella, and at least one of the functional units comprises at least one of the following:

a light module, a power module, and an audio module.

14. An electronic accessory for a shade structure, the electronic accessory comprising:

a power supply unit configured to be supported beneath a component of a shade structure, the power supply unit comprising a housing having a lower surface with a recess disposed therein;

a first functional unit that utilizes electrical power from the power supply unit to perform a function, the first functional unit comprising an upper surface having a power transfer support integrally formed or rigidly attached thereto, the power transfer support comprising at least two projections laterally extending from a central body, the at least two projections each comprising an electrical contact,

wherein the recess of the lower surface of the power supply unit housing comprises at least two laterally extending regions each corresponding to one of the at least two projections, each laterally extending region being adjacent a support surface disposed within the housing,

the projections and laterally extending regions being arranged such that insertion of the projections into the laterally extending regions, and relative rotation of the functional unit with respect to the power supply unit, positions the projections to be supported by the support surfaces and engages the electrical contacts of the projections with corresponding electrical contacts disposed within the housing of the power supply unit;

a second functional unit comprising an upper surface having a power transfer support integrally formed or rigidly attached thereto;

a first arrangement wherein the power transfer support of the first functional unit is connected to the power supply unit, and the power transfer support of the second functional unit is connected to the first functional unit, the second functional unit being positioned below the first functional unit; and

a second arrangement wherein the power transfer support of the second functional unit is connected the power supply unit, and the power transfer support of the first functional unit is connected to the second functional unit, the first functional unit being positioned below the second functional unit.

15. The electronic accessory of claim 14, wherein at least one of the projections comprises a larger width than at least one other projection, and a corresponding laterally extending region comprises a larger width that at least one other laterally extending region.

16. The electronic accessory of claim 14, wherein the laterally extending regions are each recessed with respect to the lower surface by an amount greater than a depth of a corresponding projection.

17. The electronic accessory of claim 14, wherein the projections are arranged about a perimeter of the central body in a manner that enables the projections to be inserted into the laterally extending regions in only one rotational position of the first functional unit with respect to the power supply unit.

18. The electronic accessory of claim 14, wherein the power transfer support comprises at least one additional projection laterally extending from the central body that does not comprise an electrical contact.

19. The electronic accessory of claim 14, wherein the first functional unit comprises a housing having a lower surface with a second recess disposed therein, and

wherein, in the first arrangement, the second recess is configured to provide electrical power to the second power transfer support, and to support a weight of the second functional unit through the second power transfer support.
