Abstract

A multidirectional support device is configured to move upon a traversed surface and includes a base. A multiaxial mobility element is attached to the base and includes main and secondary rolling elements having a main rolling axis and a secondary rolling axis The main rolling element is configured to allow rolling about the main rolling axis, and the secondary rolling element is configured to allow rolling about the secondary rolling axis. The multiaxial mobility element is arranged to support the base in a first stabilized equilibrium when the base is moving on the traversed surface and supported by the multiaxial mobility element. A controlled-mobility element is configured for controlled mobility and attached to the base. In the first stabilized equilibrium, the controlled-mobility element does not impede multidirectional movement of the device; and in a second stabilized equilibrium, the controlled-mobility element engages the traversed surface, impeding the multidirectional movement.

Dependent claims

A multidirectional support device configured to move upon a traversed surface, the multidirectional support device comprising:

(a) a base;
(b) a multiaxial mobility element attached to the base, the multiaxial mobility element including:
(i) a main rolling element having a main rolling axis (M) and a secondary rolling element having a secondary rolling axis(S), the main rolling element being configured to allow rolling about the main rolling axis (M), and the secondary rolling element being configured to allow rolling about the secondary rolling axis(S);
and
(ii) the multiaxial mobility element being arranged to support the base in a first stabilized equilibrium when the base is moving on the traversed surface and supported on the traversed surface by the multiaxial mobility element, so that the base has multidirectional mobility on the traversed surface;
and
(c) a controlled-mobility element configured for controlled mobility and attached to the base so that:
(i) in the first stabilized equilibrium, the controlled-mobility element does not impede a multidirectional movement of the multidirectional support device;
and
(ii) in a second stabilized equilibrium, the controlled-mobility element engages the traversed surface and thereby impedes the multidirectional movement of the multidirectional support device.
