Abstract

Subject of the invention is a driving mechanism for wheelchairs, where the levels of the supporting wheel (9) and driving wheel (16) are parallel to the axis of the wheelchair (2) wheels, which holds the handle (1). Its length is larger than the size of the wheel (9). This allows a displacement of the gripping part (16) of the driving wheel (9), which at the same time prevents the touching of tyre (9) by hand in such a way that it is unlikely that a part of the clothes will get dirty or to injure one's healthy hand. Despite the additional assembly of the driving mechanism the wheelchair still features all properties of a classical wheelchair concept.

Description

VUTE SREČKOVUTE SREČKO

Predmet izuma je pogonski mehanizem, prikazan na Fig. 1, sestavljen iz dveh ročic 1 in osrednjega dela pogonskega mehanizma, ki je z matico 4 pritrjen na glavno os 2. Pogonski mehanizem se sestoji iz nosilne plošče 3, ki je pritrjena z matico 4 na vijačnik pogona 15. Na nosilni plošči 3 sta še pritrjena vezna vijačnika 10, ki sta omejena z odmičnimi vzmetmi 5, ki nam služita, da odmakne ročici 1 od kolesa 9 v primeru, ko se ne poganjamo z ročicami ali pri spremembi giba ročice.The subject of the invention is the drive mechanism shown in FIG. 1, consisting of two arms 1 and a central part of the drive mechanism, which is secured to the main axis by a nut 4. The drive mechanism consists of a carrier plate 3, which is secured by a nut 4 to the drive screw 15. There are two more on the carrier plate 3. fastened connecting screws 10, which are limited by the camshafts 5, which serve to move the levers 1 away from the wheel 9 in the event that we are not driven by the levers or when the lever movement is altered.

Uporabnik invalidskega vozička povleče ročici 1 obojestransko h kolesu 9. Gumijasti vložek 8, ki je pritrjen z vijakom 13 na ročici 1 se tesno nalega na kolo 9 s premikom ročice 1 naprej ali nazaj in tako premikamo voziček. Ob vrtečem se kolesu 9 s pomikom ročic k sedežu vozička in s pomočjo tesno naležnega gumijastega vložka 8, ki je na ročici 1, voziček tudi ustavimo.The wheelchair user pulls the lever 1 on both sides of the wheel 9. The rubber insert 8, which is fixed by a screw 13 on the lever 1, rests tightly on the wheel 9 by moving the lever 1 forward or backward to move the cart. The trolley 9 is stopped by rotating the wheel 9 by moving the handles to the seat of the trolley and by means of the tightly sealed rubber insert 8 on the handle 1.

Kljub dodatno vgrajenem pogonskem mehanizmu, ki je predmet izuma, je invalidski voziček še vedno zložljiv in tako primeren za transport.Despite the addition of the drive mechanism of the invention, the wheelchair is still foldable and thus suitable for transport.

Omenjeni invalidski voziček, ki služi kot najpogostejše prevozno sredstvo za posamezne bolnike ali ostarele osebe, ki še lahko uporabljajo svoje zdrave roke in si pri tem ne umažejo svojih oblačil ali celo poškodujejo svoji roki. Kajti namesto prejema ročic nikakor ne morejo segati v delovno območje kolesa.This wheelchair serves as the most common means of transportation for individual patients or the elderly, who can still use their healthy hands without dirtying their clothes or even damaging their own hands. Because instead of receiving the levers, they cannot reach the working area of the bicycle.
