  • Patent number: 8529655
    Abstract: The present invention provides a dust collector structure, especially a low-cost and simplified dust collector structure, which includes a leg frame set, an air-guiding box and a driving unit. The leg frame set includes two inverted U-shaped frame rods which are integrally formed and correspond to each other. The air-guiding box is arranged across top ends of the two frame rods, and is made by correspondingly closing an upper cover and a lower cover which are formed through integral draw molding. A driving unit for driving a blowing fan is arranged at an end of the air-guiding box. An air-filtering bag and a dust-collecting bag corresponding to each other are arranged at an end opposite to the driving unit on the upper and lower covers of the air-guiding box. Thus, structural components can be greatly simplified.

  • Publication number: 20130229791
    Abstract: A bidirectional lighting device for a rim includes a casing, a light-emitting module, a reflecting element, and a power supply unit. The casing includes a lower base and an upper cover both provided with a transparent region respectively. The light-emitting module is received in the casing and has light-emitting diodes arranged in a strip. The reflecting element is mounted in the casing to correspond to the transparent regions. The reflecting element has a first reflecting surface and a second reflecting surface both located on one side of the light-emitting diodes. The light generated by the light-emitting diodes is reflected by the first and second reflecting surfaces to exit the transparent regions. The power supply unit is received in the casing to be electrically connected with the light-emitting module. Thus, the light of the light-emitting diodes can be emitted out of the casing in two directions.

  • Publication number: 20130221304
    Abstract: A safety gate has a doorframe, a fence door and a repositioning unit. The doorframe has a base frame, a first side frame, and a second side frame. The repositioning unit is mounted on a bottom of the fence door and has a repositioning recess. The repositioning recess selectively engages a top of the base frame and has two opposite guiding surfaces. When the fence door is open at an angle under 5 degrees relative to the doorframe, one of the guiding surfaces abuts a side of the top of the base frame. Because the guiding surface is curved and inclined relative to the fence door and because a distance between the guiding surfaces is decreased gradually, the guiding surface gradually rotates the fence door to close. As a result, the repositioning unit can close the fence door that is open slightly at a small angle.
