Patent number: 7665706Abstract: A suction-adhered device includes a main body, suction cup units, and suction power detection units. The main body is provided with chambers. Each of the suction cup units includes a suction cup received in the chamber, and a safety lever projected from the upper side of the main body and movably connected to the suction cup with an elastic element mounted between them. Each of the suction power detection units includes a probe received in a long hole near the chamber to partially project from the long hole, and an indicating member visible via a window formed on a top of the main body above the long hole. When the suction cup is loosened from a mounting surface, the indicating member is turned by an elastic element to show a warning indicating zone thereof, so that a user may be timely warned to re-mount the main body.Type: GrantFiled: January 3, 2007Date of Patent: February 23, 2010Inventors: Li-Sheng Chien, Ho Chien-Chang

Patent number: 7661638Abstract: A suction cup structure includes a suction cup, a lifting rod, a holder base, a slide bolt, a radial arm and an axial-bolt. The lifting rod is vertically connected to the suction cup, and has a through hole with horizontal penetration. The sleeve of the holder base has a rotation axis hole with horizontal penetration and a slide notch. The lifting rod is disposed in a sleeve of the holder base. The suction cup is under a disk body of the holder base. The slide bolt passes through a first hole of the button arm, the slide notch and the through hole. The axial-bolt also passes through the rotation axis hole and a second hole of the button arm. By pressing a button end of the button arm, an activation piece of the button arm rotates based on the axial-bolt to pull the slide bolt. The slide bolt then slides toward the upper portion from the lower portion of the first hole, and slides into the slide notch simultaneously to lift the lifting rod. The suction cup is therefore lifted to generate the suction.Type: GrantFiled: May 31, 2007Date of Patent: February 16, 2010Assignee: Mitac International Corp.Inventor: Lin-Chien Yu

Patent number: 7658354Abstract: A suction device includes a sucking member having a connecting body connected integrally to a flexible disc body that is disposed under an upright sleeve, a connecting member disposed in the sleeve and connected to the connecting body, an operating member connected to a pivot rod extending through the sleeve, and a cam body accommodated in a cam-accommodating space in the connecting member and pivotable together with the pivot rod. The operating member is operable so as to pivot the pivot rod and the cam body such that an assembly of the connecting member and the connecting body is pulled upwardly by the cam body, thereby forming a vacant space between a central portion of the disc body and a supporting surface to which a peripheral portion of the disc body is attached sealingly.Type: GrantFiled: August 31, 2007Date of Patent: February 9, 2010Assignee: Lite-On Technology Corp.Inventor: Chen-Hsing Wang

Patent number: 7648109Abstract: A sucker includes a fixing seat, a sucker body, a control handle and a control valve. The sucker body has a first side provided with a recess and a second side provided with a connecting hole connected to the recess. The control valve includes a valve stem movably mounted on the fixing seat and movable to stop the recess. Thus, the valve stem can be pulled outwardly to detach from the recess of the sucker body so as to connect the connecting hole and the recess of the sucker body and to connect the connecting hole of the sucker body to the ambient air so as to break the vacuum state of the sucker body so that the sucker body can be removed from a surface easily and quickly.Type: GrantFiled: February 21, 2008Date of Patent: January 19, 2010Inventor: Lung-Chih Chen
