Secure mechanism of portable accessory device for shading device
First Claim
1. A portable accessory device for a shading device, comprising:
- a housing which comprises a first housing body, a second housing body defining a mounting slot when said first and second housing bodies are coupled with each other, a battery module, and a control unit, wherein said mounting slot has a size for a shaft of said shading device fitting therewithin;
an accessory unit supported in said housing for providing an addition function for said shading device, wherein said battery module and said control unit are mounted in said housing to electrically connect with said accessory unit so as to control said function thereof, wherein said battery module comprises a battery provided in said second housing body, and a terminal connector movably mounted in said second housing body to electrically connect said battery with said control unit in said first housing body when said second housing body is mounted on said first housing body; and
a shaft adjusting arrangement comprising two adjustable retainers for adjusting the size of said mounting slot for said shaft of said shading device, wherein each of said adjustable retainers comprises a retention arm, having a pusher surface facing towards said mounting slot, slidably mounted at said first housing body, wherein said pusher surfaces of said retention arms are facing with each other and are arranged for biasing against an outer surface of said shaft of said shading device until said shaft thereof being fitted at said mounting slot so as to substantially mount said housing of said portable accessory device at said shaft of said shading device, wherein said adjustable retainers are slidably coupled at said first housing body in a radially movable manner at a position that said pusher surfaces of said adjustable retainers are protruded from a circumferential wall of said mounting slot for biasing against said outer surface of said shaft, wherein said shaft adjusting arrangement further comprises two actuating members pivotally supported at said first housing body to couple with said adjustable retainers respectively, wherein each of said actuating members has a pivot end pivotally coupling with said corresponding adjustable retainer and an opposed pushing end arranged in such a manner that when said pushing ends of said actuating members are pressed towards each other to pivotally move said pivot ends thereof away from each other, said adjustable retainers are driven to radially slide away from each other so as to adjust a distance between said pusher surfaces of said adjustable retainers.

Abstract
A portable accessory device includes a housing having a mounting slot, an accessory unit supported in the housing, and two adjustable retainers for adjusting the size of the mounting slot for a shaft of a shading device. Each of the adjustable retainer includes a retention arm, having a pusher surface facing towards the mounting slot, slidably mounted at the housing, wherein the pusher surfaces of the retention arms are facing with each other and are arranged for biasing against an outer surface of the shaft of the shading device until the shaft thereof being fitted at the mounting slot so as to substantially mount the housing at the shaft of the shading device. Therefore, the portable accessory device is adapted to detachably mount at the shading device to provide an additional function via the accessory unit for users to have high quality shading device.
