| 20140284898 | RECUMBENT VEHICLE - A recumbent vehicle is disclosed, which generally consists of a front, seat and rear chassis. The seat chassis is operatively connected to upper and lower pivot joints, which allow for the seat chassis, and thus the rider, to move independently from the remainder of the vehicle. Said upper and lower pivot joints are each comprised of subcomponents such as spherical axial bearings along with a coil to create said independent movement, which manifests itself during turns and when hitting obstacles on the terrain. The rider can control the direction of the recumbent vehicle by means of a steering arm. | 09-25-2014 |
| 20140319799 | Quick Release Structure for a Bicycle - A quick release structure for a bicycle includes a locking rod fixed securely, wherein the locking rod has a polygonal groove formed therein. The driving post of the locking rod includes a polygonal head. As desiring to lock the locking rod on the bicycle frame or to unlock the locking rod from the bicycle frame, the polygonal head of the driving post retains with the polygonal groove of the locking rod so as to rotate the locking rod. When the locking rod is rotated tightly, the polygonal head of the driving post removes from the polygonal groove so that the locking rod cannot be rotated, and the driving post of the locking rod does not drive the locking rod to rotate loosely after vibration, thereby obtaining positioning safety. | 10-30-2014 |
| 20150054249 | CARDBOARD-BASED UNIT - The present disclosure provides a cardboard-based unit, structural elements comprising said unit and land-vehicles comprising said units and structural elements. | 02-26-2015 |

The tricycle has a first riding mode with single front wheel and double rear wheels and a second riding mode with double front wheels and single rear wheel. The tricycle of the present invention may easily switch between two riding modes and may increase the fun of riding. | 12-03-2015 |
| 20160114845 | HEIGHT ADJUSTABLE BIKE - Described herein is a bike including a frame member linking the front and rear wheel(s) made up of a first forward section or sections extending from the front wheel(s) and a second rear section or sections extending from the rear wheel(s). The section endings mate about a lockable connection assembly that is also in communication with a seat-post connected to the seat. The frame sections pivot about a connection assembly axis in a direction perpendicular to the bike frame and the seat-post is able to be moved independent of the frame sections. A key advantage of the above bike is the high range of height adjustability allowing the bike to be used by range of different sized users. Height adjustment is also very easy and may be done toolessly. Further, maintaining the seat in a desired riding alignment independent of frame movement is important otherwise the rider position will change relative to the handlebars leading in extreme cases to falls from the bike. Use of gas assisted injection moulding in bike manufacture is also described. | 04-28-2016 |
