20110308880 | WHEELCHAIR STRUCTURE - A wheelchair structure includes a wheelchair frame, an auxiliary drive device and a combined frame. The combined frame has an assembly base frame, a moveable rack assembly and an elastic support. The assembly base frame has a horizontal hack lever, at least a plug-in rod section, a positioning end and object fixed seat assembly portion. The sleeving portion of the moveable rack assembly is inserted into the holding space of the plug-in rod section, and a limiter is used to prevent the moveable rack assembly from disengagement. The moveable rack assembly is provided with a limiting end. With this configuration, when the limiting end is abutted onto the positioning portion, the positioning end of the horizontal hack lever can be locked onto the assembly position. With this simple and efficient structure, the user can be benefitted from rapid assembly and ease-of-operation with improved applicability. | 12-22-2011 |
20110304121 | QUICK-RELEASE MECHANISM - The present invention provides a quick-release mechanism of assembly structure, of which said quick-release mechanism includes an exterior sleeve, expansion link sections, a threading portion of driving section, elastic part and a brake. The expansion link sections are arranged at interval into the holding space of the exterior sleeve. At least one elastic part is arranged into the holding space of the exterior sleeve, enabling retraction or protruding of the expansion link sections. The present invention is characterized in that the driving section of the brake is mated with the threading portion of driving section, so that the brake can drive the expansion link section to control the actuating state of the positioning end in either positioning or release mode. With this configuration, the users can dismantle or operate the device easily in either positioning or release mode. | 12-15-2011 |
20110101642 | ASSEMBLY AND POSITIONING MECHANISM FOR WHEELCHAIR AND AUXILIARY OPERATING LEVER - An assembly and positioning mechanism for wheelchair and auxiliary operating lever. The assembly and positioning mechanism has a swinging angular adjustment seat and a liftable pivoting seat of operating lever. The angular adjustment seat has an assembly side of locating rack and an assembly side of pivoting seat. The assembly side of locating rack is pivoted onto the locating rack via an adjuster, and the angular adjustment seat can swing rotarily. The pivoting seat of operating lever consists of a connecting side and a mating side of operating lever. The pivoting seat of operating lever can move vertically via a limiting portion. The mating side of operating lever is fitted with a limiting rabbet and a guide opening extended in an outward-dipping state. The mechanism can swing and also shift vertically, making it possible to control the guide opening of the mating side of operating lever for outward-dipping extension. | 05-05-2011 |
20110095508 | QUICK-RELEASE MECHANISM FOR WHEEL CHAIR AND AUXILIARY OPERATING LEVER - The present invention provides a quick-release mechanism for the wheelchair and auxiliary operating lever. The quick-release mechanism includes a pivoting seat of the operating lever, limiting rabbet and snapping rod. The pivoting seat of operating lever is provided with convex lug, and the limiting rabbet with mouthed profile is arranged at the front of the convex lug. The limiting rabbet forms a guide opening and a bracing flange. The guide opening is extended in an outward-dipping state. A snapping rod is arranged transversely onto the operating lever. The present invention allows to save the components and realize rapid removal and assembly with improved applicability. | 04-28-2011 |
20100012404 | WHEELCHAIR - The present invention provides a wheelchair structure, which is available with a handle, seat and wheel body. The handle is provided with an integrated control seat, and the wheel body is provided with auxiliary drive unit and combined positioning member. The integrated control seat can be assembled securely onto the wheelchair handles of different diameters and curvatures, and the swinging angle can be adjusted flexibly. Thus, it is possible to guarantee outstanding adaptability of assembly, efficient and convenient operation with improved applicability. | 01-21-2010 |
20080199771 | BATTERY POSITIONING STRUCTURE OF AN ELECTRIC VEHICLE - The improved battery positioning structure of an electric vehicle includes a flexible pull handle, being mounted at one side of a battery and forming a handle portion and at least one snapping portion. The snapping portion can protrude from the hole at one side of the battery and is recessed if the handle portion is pulled upwards. A positioning groove is placed onto a side wall of the chamber and is used for positioning of the snapping portions. When the battery is removed, the handle portion of the flexible pull handle is pulled to enable the snapping portions to be disengaged from the positioning groove, thus releasing the battery. The batter can be quickly lifted via the handle portion. When the battery is returned to be positioned in the chamber, the handle portion is pressed to enable the snapping portions to be fixed securely into the positioning groove. Thus, the battery of the electric vehicle can be removed and positioned more simply, quickly and conveniently. | 08-21-2008 |
