Disclosed is a hands and feet operated folding bicycle which is easily convertible into a hand bike suitable to be used by persons who have serious handicap in the lower body. The steering of the bicycle is accomplished as a rider moves the center of his/her body toward a desired traveling course. Also, considering the folding of the hands and feet operated folding bicycle, if a saddle backrest is laid down forward, a pair of axles, which are installed foldably at opposite sides of a rear wheel frame housing, are pulled forward by axle drive rods coupled to axle drive rod end hooks of a saddle backrest frame, whereby a pair of rear wheels, which are coupled to knuckle arms at opposite ends of both the axles, are pulled and gathered forward to thereby complete the folding of the bicycle.


In this case, since the knuckle arms are connected to a pair of tie rods, and in turn, the tie rods are connected to opposite sides of a steering bar by means of a pair of tie rod ends, the tie rods can serve to steer the bicycle on the basis of the tilt of the rider's body during traveling. Also, in the course of folding the bicycle, the tie rods can serve to allow the knuckle arms to be kept parallel to each other while facilitating the forward displacement of the knuckle arms.

Thereby, the pair of rear wheels, which are rotatably coupled to outer sides of both the knuckle arms, respectively, can be displaced forward while being kept parallel to each other. Also, since a second fork for supporting a front wheel is connected to a rear wheel frame by means of foldable hinges, if the second fork is released by use of a second fork fixing handle having an eccentric cam, a front wheel mechanism can be folded downward.

The second fork is also hingedly coupled, at a front end thereof, to a front end of a first fork that constitutes the front wheel mechanism along with the second fork. In turn, a first fork fixing bush, which is hingedly coupled to a control bush supporting bar coupling bracket, is inserted into the first fork in such a manner that it is movable to be secured at a desired position. With this configuration, if a first fork control bush fixing handle is released, the first fork can be folded

Hyundai revealed a new concept crossover called the QarmaQ at the Geneva Motor Show this week. Designed at Hyundai Motor Europe's Design and Technical Center and engineered in close cooperation with GE Plastics, QarmaQ is a showcase for 30 technologies that will find their way into Hyundai's new models to be rolled out from 2008-2014.
The wrap-around GE Lexan windscreen and extensive use of GE polycarbonate glazing materials provides a weight saving of up to 50 percent in relation to glass, while simultaneously allowing more adventurous shapes than flat glass. The glazing features a unique technology from Exatec which deposits a thin protective layer of glass on the Lexan to add protection from scratching and the effects of weathering.

Advanced Technology Inside and Out: Hyundai ATDV Features Innovative Applications Utilizing GE Materials

At the Geneva Motor Show here, GE Plastics' high-performance composites and thermoplastics is taking the spotlight with close to 30 diverse applications for Hyundai's advanced technology development vehicle (ATDV), the QarmaQ. The crossover utility vehicle (CUV) is a joint project of GE Plastics and Hyundai to demonstrate the design freedom and practicality of using plastics in components traditionally manufactured from metal, glass, and thermosets. It features GE's advanced technologies in five key areas: the Elastic Front*, exterior, interior, lighting systems, and underhood.

Among the benefits of the GE Plastics materials are a weight reduction of up to 60 kg that can offer an average fuel savings of up to 80 litres/year; improved pedestrian safety; and the ability to create complex, 3D shapes.

SEOUL - April 5, 2007: Kia Motors Corporation is staging the world premiere of its all-new KND-4 concept car today (Thursday) at the Seoul International Motor Show. Designed to reassert Kia's credentials as a leading brand in the 4x4 and RV vehicle sectors, the new SUV concept car projects a dynamic, powerful character and exudes a strong sense of individuality. Although clearly a 'concept car,' the Luminous Green, three-door, 4466mm-long KND-4 gives a bold hint at how future Kia compact SUV models might look.

This is the first Kia vehicle to demonstrate the company's renewed passion for 'Designology' (Design & Technology) - its ongoing commitment to making automobiles that are both more stylish and technologically advanced.

"The KND-4 is an exciting vehicle which showcases Kia's increasingly sophisticated styling and advanced technologies that will give our future products an even stronger and more distinctive road presence," commented Mr Yong-Hwan Kim, Senior Executive Vice President and COO of Kia Motors Corporation. "Over time, elements of this concept SUV will evolve into our next-generation lineup, ensuring the continued global popularity of our already competitive 4x4 models."

The exterior styling of KND-4 is designed to appeal to consumers who crave freedom and an active lifestyle, while removing the traditional boundaries between urban and rural vehicles to create an SUV that looks great in any location. The sleek, rounded nose features LED headlights, while flared wheelarches wrap around large diameter 20-inch wheels and 245/40 R20 low-profile tyres, which appear to bulge out of the vehicle's form.
