1. Technical Field
The present disclosure relates to a stand assembly for portable devices.
2. Description of Related Art
Due to small size and light weight, notebook computers are easy to carry and use in a variety of occasions. However, people find it inconvenient to use the notebook computer where there no appropriate support to set the computer on, such as at certain outdoor locations.
Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
The present disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

The bearings 21 and 22 are respectively received in the second grooves 244 of the receiving portions 240 at the opposite ends of the sleeve 24, with outer surfaces of the bearings 21 and 22 engaging with inner surfaces of the sleeve 24. The cover 26 is mounted to one end of the sleeve 24 opposite to the seat 10, with an end of the cover 26 received in the first groove 242 of the corresponding receiving portion 240, and an outer surface of the cover 26 engaging with the inner surface of the sleeve 24. In other embodiments, the cover 26 can be mounted to the sleeve 24 by threaded fitting. The first groove 242 at the other end of the sleeve 24 fixedly fits about the shoulder 121 of the post 12. The pivot pole 28 extends through the though hole 260 of the cover 26, the bearing 21, the through hole 25 of the sleeve 24, and the bearing 22 in that order, with a low end of the pivot pole 24 received in the receiving space 120 of the post 12. The pivot pole 28 is mounted to the bearings 21 and 22 by an outer surface of the pivot pole 28 engaging with inner surfaces of the bearings 21 and 22. Thus, the pivot pole 28 can rotate with the bearings 21 and 22.

The connection member 30 is substantially U-shaped and includes a rectangular main body 32, and two plates 34 substantially horizontally extending from a top and a bottom of a side of the main body 32. The main body 32 defines a first through hole 320 perpendicular to the plates 34, and a second through hole 322 communicating with the first through hole 320 and parallel to the plates 34. A top end of the pivot pole 28 extends through the first through hole 320 of the connection member 30, with the second through hole 322 of the connection member 30 selectively aligning with one of the mounting holes 280 of the pivot pole 28. The fastener 4 extends through the second through hole 322 to engage in the mounting hole 280, to fasten the support 3 at a height corresponding to the pivot pole 28.
Each leg 40 includes a bar-shaped rotatable leg 42 and a slidable leg 44 slidably received in the rotatable leg 42. A first end of the rotatable leg 42 is pivotably mounted to the connection member 30 between the plates 34. The rotatable leg 42 longitudinally defines a slide hole 420 therein through a second end of the rotatable leg 42 opposite to the first end, and a slot 422 in a top surface of the rotatable leg 42 communicating with the slide hole 420. A first end of the slidable leg 44 slidably received in the slide hole 420 defines a fastening hole (not shown), such as a screw hole. A fastener 45, such as a screw, extends through the slot 422 to engage in the screw hole of the slidable leg 44 to fasten the slidable leg 44 to the rotatable leg 42. A pin 440 perpendicularly extends from a second end of the slidable leg 44 opposite to the rotatable leg 42, facing the other leg 40. A tab 442 perpendicularly extends from the second end of the slidable leg 44, adjacent to the pin 440 and opposite to the first end of the rotatable leg 42 about the pin 440.
Each block 50 includes a round main body 52, and a stop portion 54 extending from the main body 52 at a tangent. The main body 52 defines a pivot hole 520. The pin 440 of a corresponding slidable leg 44 is pivotably engaged in the pivot hole 520, to pivotably mount the block 50 to the slidable leg 44. The tab 442 can resist against the stop portion 54 to prevent the block 50 from rotating excessively.
