One of the painfully complicated and nagging social problems consists in the fact that hundreds of thousands of our kin, whether in their families, and/or specialized medical establishments, suffer from ailments which render them practically immobile so that they cannot take care of their even basic needs and requirements. Some of these unfortunates, however, make, either all by themselves or with the help of their near and dear ones, some simple aids and gadgets which make them more or less independent. Unfortunately, most of these "aids" are rather primitive and unreliable, not to mention other obvious snags associated with them. In dealing with this problem modern science has a key role to play together with our industrialists. The aforesaid problem was on the agenda of a special exhibition 'Transport and Special Technical Aids for Invalids" held in Moscow in August 2002. It was hosted by the State R&D Center of the Russian Federation known as the "Scientific Research Institute of Automobile and Automotor Technology" (NAMI).
One of the examples of successful cooperation of science and technology is offered by the aforesaid NAMI and the Serpukhov Automobile Works which produced back in the 1950s a four-wheel motorized invalids' chair (SZA) instead of the earlier three- wheeler (SZL). Later on the factory, working in conjunction with NAMI and the Moscow Moskvich Factory of Mini-Cars, designed and built the Sputnik mini-car (SMZ-NAMI-086) and other mechanical aids for invalids with locomotor problems. Today specialists of the Serpukhov Car Plant are working on an advanced version of the Oka mini-car (SeAZ-11113-03) with automatic steering gear for invalids with only one hand or leg. Many of these engineering achievements are unparalleled anywhere in the world.
Most of the exhibits at the show were wheelchairs. One of the Moscow companies Invaengineering is specializing on a wide range of these products featuring different engi-
neering solutions. One such example is the II-2101-SP wheelchair which has a folding frame of thin-walled steel pipes; its rare wheels (24 inches) are equipped with solid polyurethane tyres and supports for arms (for propelling and steering the chair). Its front wheel (8 inches) have solid polyurethane tyres and the vehicle has regulated parking brakes; removable arms and legs rests with adjustable belts (footboards can be lifted and turned outside in order to help position the wheelchair at a table or for exit from it). The wheelchair weighs 19 kg and its lift is 100 kg.
Another important area of Inva-engineering is research and development of special vans for transporting invalids in wheelchairs. Engineers are now working on hydraulic lifts on the basis of some of the most advanced world standards and also on mini-lifts for the transport of patients inside buildings and premises.
The display of the Moscow Institute of Power Engineering (Technical University) featured the UYUT wheelchair INNEL-4 with an electric drive. The exhibit features the best engineering achievements in this field providing for increased comfort and safety of the user and a long service life of the vehicle.
The Stavrovsky Factory of Automobile and Tractor Equipment, working on a license of the Germany Mayra Co., is producing electric drives INNEL-4 for invalid chairs Type 400 and 700 with a hand drive. The electric drives include two DC reducer motors placed on a folding frame. Each drives one rare wheel through what they call a friction roller. The wheelchair has reversible brakes and is powered by storage batteries A 512/60 with electrolyte supplied by the German firm AF Sonnenshine. It is equipped with a Kulon charger. The wheelchair is adjusted for its user with the help of a joystick device located on an arms rest on the right or the left side. Its maximum speed is 6 km/h; current tension-12 V; maximum operating range without battery recharging-20 km; maximum angle of climb- 10; and carrying capacity-100 kg.
Several wheelchairs on the display were produced by the Kalugapult-mash factory, including those with electric drives and an attachment for persons accompanying an invalid.
...Despite its narrow specialization and a rather limited "menu" of products and manufacturers, the NAM I show has been an obvious success bringing to the attention of not only experts, but the public at large, a really vital area of human endeavor.
