  • Patent number: 8251332
    Abstract: A support stand includes a bracket and a base connected with the bracket. The bracket includes a main body, a movable member, and a resilient member. The main body defines a receiving slot therein, and the movable member is partially received in the receiving slot, with opposite ends of the resilient member resisting the main body and the movable member. The base includes a latching member sleeved on the main body of the bracket. The latching member includes a latching portion for impelling and guiding the movable member to be received in the receiving slot of the main body, and the movable member to contact the resilient member. After the movable member passes over the latching portion, an elastic force created by the resilient member extends the movable member from the receiving slot of the main body, and the movable member is latched in the base.

  • Patent number: 8046875
    Abstract: A hinge assembly includes a pivot shaft, a rotary member and a steady member sleeved on the pivot shaft. The rotary member and the steady member faces each other and are rotatable relative to each other. The rotary member forms a first peak, and the steady member forms a second peak. A friction portion is formed between the rotary member and the steady member. A thickness of the friction portion exceeds or equals to a thickness of either of the first peak or the second peak, and is less than the combined thickness of the first peak and the second peak. A support mechanism using the hinge assembly is also provided.

  • Patent number: 7789354
    Abstract: An adjustable support mechanism (30) includes a fixed unit (70), an adjustable suspension unit (80) and a connecting unit (90). The adjustable suspension unit is slidably mounted on the fixed unit. The connecting unit is configured for connecting the fixed unit and the adjustable suspension unit. The connecting unit comprises a first elastic member (96) and an adjusting bracket (94). Opposite ends of the first elastic member are connected to the fixed unit and the adjustable suspension unit correspondingly. The adjusting bracket includes two rotary wheels (942, 945) and a coiling member (944) looped around the rotary wheels. The adjustable suspension unit is fixed to the coiling member. At least one of the rotary wheels is rotatable relative to the fixed unit to coil the coiling member around the rotary wheels, sliding the adjustable suspension unit relative to the fixed unit.
