Abstract
The invention relates to a small vehicle, particularly a wheel chair, having a modular structure including a main component, at least one pivotable wheel which is adapted to be detachably mounted at said main component via a quick release device, at least one driving wheel adapted to be detachably mounted at said main component via a quick release device and a seat component which is adapted to be detachably mounted at said main component via a quick release device. The main component comprises a main body to which four arms for supporting the wheels are springably coupled. The quick release devices between said main component and said wheels are disposed between said arms and said wheels, respectively.
Claims16
A wheel chair having a modular structure comprising:
- a main component;
- at least one pivotable wheel, which is detachably mounted at said main component by a quick release device;
- at least one driving wheel which is detachably mounted at said main component by a quick release device;
- and
- a seat component, which is detachably mounted at said main component by a quick release device;
- wherein said main component comprises a main body designed as a monocoque construction to which four arms for supporting said wheels are coupled;
- said four arms are springably coupled to said main body;
- and
- said quick release devices between said main component and said wheels are disposed between said arms and said wheels, respectively,
- wherein, when said wheels are detached, said four arms extend in substantially a common plane so that the main component including the main body and said four arms coupled thereto without said wheels has a flat shape;
- and
- wherein a smallest cuboid having side lengths a, b and c which can envelop said main component including said main body and said four arms connected thereto without wheels has a side length c which is smaller than half of said side lengths a or b, respectively, wherein said side lengths a and b extend in said common plane of said four arms.
A wheel chair, having a modular structure comprising:
- a main component;
- at least one pivotable wheel which is detachably mounted at said main component by a quick release device;
- a quick release device for mounting a seat component at said main component;
- wherein said main component comprises a main body designed as a monocoque construction to which four arms for supporting said wheels are coupled;
- said four arms are springably coupled to said main body;
- and
- said quick release devices between said main component and said wheels are disposed between said arms and said wheels, respectively,
- wherein, when said wheels are detached, said four arms extend in substantially a common plane so that the main component including the main body and said four arms coupled thereto without said wheels has a flat shape;
- and
- wherein a smallest cuboid having side lengths a, b and c which can envelop said main component including said main body and said four arms connected thereto without wheels has a side length c which is smaller than half of said side lengths a or b, respectively, wherein said side lengths a and b extend in said common plane of said four arms.
A wheel chair having a modular structure comprising:
- a main component;
- a quick release device for detachably mounting at least one pivotable wheel at said main component;
- a quick release device for detachably mounting a seat component at said main component;
- wherein said main component comprises a main body designed as a monocoque
- construction to which four arms for supporting said wheels are coupled;
- said four arms are springably coupled to said main body;
- and
- said quick release devices between said main component and said wheels are disposed between said arms and said wheels, respectively, upon detachably mounting said wheels at said main component,
- wherein, when said wheels are detached, said four arms extend in substantially a common plane so that the main component including the main body and said four arms coupled thereto without said wheels has a flat shape;
- and
- wherein a smallest cuboid having side lengths a, b and c which can envelop said main component including said main body and said four arms connected thereto without wheels has a side length c which is smaller than half of said side lengths a or b, respectively, wherein said side lengths a and b extend in said common plane of said four arms.
