US 2026/0020543 A1 · WHEELCHAIR DEVICE FOR MOBILITY-CHALLENGED QUADRUPEDS WITH USER-ACTUATED SIT-DOWN ACTION

Abstract

A wheelchair device for mobility-challenged quadrupeds is disclosed. The device is configured with a user-actuated sit-down action in which an actuator element may be actuated by a user to allow the device to transition from an upright state to a collapsed state. Deflection of the actuator element causes latching element(s) to disengage from corresponding pin(s), whereupon the leg(s) of the device may be permitted to rotate relative to the frame of the device. Thus, as the quadruped initiates a “sitting down” motion, the leg(s) may pivot up alongside the frame to achieve an orientation generally parallel with the frame, putting the device in a collapsed state that permits the quadruped to sit and/or lay down safely, naturally, and comfortably. The device further includes one or more ratchet assemblies that lock the wheel(s) and help drive the device back up to its upright state when the quadruped attempts to move forward.

Dependent claims

A wheelchair device for a quadruped, the wheelchair device comprising:

a frame configured to have the quadruped situated therein;
at least one leg connected to the frame;
at least one wheel assembly connected to the at least one leg;
and
an actuator assembly operatively coupled with the at least one leg, the actuator assembly comprising:
an actuator element configured to be actuated by a user;
and
at least one latching element configured to be engaged with at least one structural feature of the at least one leg,
wherein the actuator element is operatively coupled with the at least one latching element such that actuation of the actuator element by the user causes disengagement of the at least one latching element from the at least one structural feature to permit the wheelchair device to transition from an upright state to a collapsed state.

6 more elements

A wheelchair device for a quadruped, the wheelchair device comprising:

a frame configured to at least partially accommodate hindquarters of the quadruped;
one or more legs connected to the frame by a corresponding one or more adjustable knuckle clamp assemblies;
one or more wheel assemblies connected to the one or more legs;
and
an actuator assembly operatively coupled with the one or more legs and configured to transition the wheelchair device from an upright state in which the one or more legs are oriented substantially perpendicular to a longitudinal length of the frame to a collapsed state in which the one or more legs are oriented substantially parallel to the longitudinal length of the frame, the actuator assembly comprising:
an actuator element configured to be actuated by a user;
and
one or more latching elements configured to be engaged with the one or more legs,
wherein the actuator element is operatively coupled with the one or more latching elements such that actuation of the actuator element by the user causes disengagement of the one or more latching elements from the one or more legs to permit the wheelchair device to transition from the upright state to the collapsed state.
