20100187034 | Fixing device for a foldable chassis of an electric walk-substituting vehicle - A walk-substituting vehicle includes a foldable chassis, a steering mechanism, a seat assembly, and a fixing device, which is movable to a fastening portion to prevent the chassis from folding from an in-use position; the chassis includes a main part and a footrest part; the vehicle can be moved to a folded configuration, wherein the chassis is folded, and the steering mechanism and the seat assembly lie on the chassis; the fixing device includes a pulling member pivoted on the footrest part, a joining member pivoted on the pulling member, and a pushing member joined on and slideable along a receiving recessed portion of the pulling member; when the fixing device is in the fastening position, the joining member will be hooked over the main part of the chassis, and the pushing member engaged with the joining member to prevent the joining member from pivoting relative to the pulling member. | 07-29-2010 |
20100327557 | Electric wheelchair - An electric wheelchair is disclosed. The electric wheelchair includes a main frame correspondingly pivoted with a foldable chair while the folding of the chair connects with an accessory tip wheel. Moreover, the main frame is disposed with main wheels and a front wheel set arranged on front of the main wheel correspondingly on each of two sides thereof. A footrest that is pulled out or stored in the main frame is arranged between the two front wheel sets. In use, the footrest is pulled out of the main frame and the chair is moved and unfolded. At the same time, the accessory tip wheel tilted a little angle is extended out of the main frame by a connecting member. Thereby the problem caused by movement of the center of gravity of the wheelchair while moving can be solved and the safety of users is ensured. | 12-30-2010 |
