Abstract

The invention concerns a collapsible wheelchair frame which is constructed so that the wheelchair can be easily folded for carrying or transportation, without the use of any additional tools. In addition, the proposed construction provides sufficient solidity in using the wheelchair. The construction of a collapsible wheelchair frame in accordance with the invention allows the linking of joint parts (A through F) with flexible, interlinked crossbars (5, 5', 10, 10', 11, 11') in such a way that the frame is longitudinally and transversely foldable by pulling out seat rods (13, 13') stuck into the upper front joint parts and tied together by seat canvas (14). In folded state all four upper joint parts (A, B, E, F) are brought closer to each other in such a way that, the each two opposite upper joint parts (A and F, B and E) are approached.

Description

ZLOŽLJIVO OGRODJE INVALIDSKEGA VOZIČKADISABLED FRAME OF THE DISABLED TROLLEY

Predmet izuma je zložljivo ogrodje invalidskega vozička, katerega konstrukcijska izvedba omogoča enostavno zlaganje invalidskega vozička pri njegovem prenašanju ali prevažanju, brez uporabe dodatnega orodja. Poleg tega pa predložena konstrukcija daje zadostno trdnost pri uporabi vozička. Izum spada v razred A 61 G 05/02 mednarodne patentne klasifikacije.The subject of the invention is a folding wheelchair frame, the construction of which allows for easy folding of the wheelchair when carrying or transporting it, without the use of additional tools. In addition, the submitted construction gives sufficient strength when using the trolley. The invention belongs to Class A 61 G 05/02 of the International Patent Classification.

-2Tehnični problem, ki ga predložena konstrukcija uspešno rešuje je izvedba takšnega ogrodja, da bo možno invalidski voziček zložiti na takšno dimenzijo, da bo enostavno prenašanje in/ali prevažanje vozička v npr. osebnem avtomobilu ob istočasni ohranitvi vseh vitalnih funkcij samega invalidskega vozička (možnost ročnega pogona, stabilnost, okretnost ipd.).-2The technical problem that the proposed construction successfully solves is the construction of such a frame that it will be possible to fold the wheelchair to such a dimension that it will be easy to carry and / or transport the trolley in e.g. the car while maintaining all the vital functions of the wheelchair itself (manual drive, stability, agility, etc.).

Invalidski voziček v standardni izvedbi, ki ga je možno zložiti ima osnovno ogrodje izvedeno tako, da sta zadnji večji pogonski kolesi pritrjeni na ogrodje, ki je prečno sestavljivo. Pri zlaganju tako izmaknemo prednjo in zadnjo prečno oporo, nakar voziček stisnemo skupaj tako, da medsebojno približamo oba dela na kaetrih sta pritrjeni pogonski kolesi.The standard, retractable wheelchair has a base frame made so that the rear larger drive wheels are attached to a frame that is foldable. When folding, the front and rear transverse struts are then removed, and the cart is then squeezed together so that the two drive wheels are attached to each other on the catheters.

Tako zložen voziček ima še vedno zunanje mere, ki so enake dimenzijam stranske projekcije sestavljenega vozička, kar pomeni, da ga zelo težko prevažamo v kabini ali prtljažniku osebnega avtomobila. Vsekakor pa je onemogočeno enostavno vlaganje oz. izvlačenje tako zloženega vozička.The folded trolley still has outside dimensions that are the same as the lateral projection dimensions of the compound trolley, which means that it is very difficult to carry in the cabin or trunk of a passenger car. In any case, it is not possible to invest easily or. pulling out such a folded cart.

Pri nekaterih izvedbah invalidskih vozičkov je možno pri sestavljanju le-teh tudi snemati kolesa, kar siscer zmanjša zunanje gabarite zloženega invalidskega vozička, po drugi strani pa otežkoča njegovo razstavljanje oz. sestavljanje.In some wheelchairs, it is also possible to remove the wheels when assembling them, which reduces the outer dimensions of the folded wheelchair and, on the other hand, makes it difficult to disassemble or disassemble it. assembling.

Konstrukcijska izvedba zložljivega ogrodja invalidskega vozička po izumu omogoča povezavo zglobnih delov z gibljivimi, medsebojno povezanimi prečkami tako, da je ogrodje vzdolžno in prečno zložljivo z izvlekom v zgornja predna zglobna dela nataknjenih sedežnih palic, ki ju povezuje sedežno platno. V zloženem položaju so medsebojno približaniThe construction of the folding wheelchair frame according to the invention allows the joints to be connected to the movable, interconnected crossbars so that the frame is longitudinally and transversely folded by pulling into the upper front articulated parts of the mounted seat rods, which are connected by a seat canvas. In the folded position, they are close to each other

-3vsi štirje zgornji zglobni deli tako, da se pri zlaganju približujeta po dva nasproti ležeča zgornja zglobna dela.-3 all four upper hinge parts so that when folding, the upper hinge joints, two opposite ones, are approached.

Izum bomo podrobneje obrazložili na osnovi izvedbenega primera in pripadajočih slik, od katerih kaže:The invention will be explained in more detail on the basis of an embodiment and accompanying drawings, of which:
