| 20080223424 | Upper arm crutch - The invention, referred to as the Upper Arm Crutch, pertains to crutches used by the disabled to facilitate walking. The Upper Arm Crutch allows the user's weight to be supported with the arm straight, reducing fatigue. The design of the arm band is such that the arm band will not inadvertently slip off the arm, yet can be removed readily by rotating the crutch handle 45 degrees in either direction. The single arm band encloses the upper arm, instead of the forearm, increasing leverage and control. The single arm band is positioned well below the armpit. The user is not inclined to support their weight by leaning on the arm bands. The design of the arm band allows the user's arm to be positioned directly above the handle such that the crutch does not tilt when weight is applied to the handle. | 09-18-2008 |

The handgrip section is substantially centered over the vertical shaft. | 03-08-2012 |
| 20100206348 | Crutch - The crutch includes a lower pole with a handgrip near the upper end thereof, and may include a forearm cuff above the handgrip in the case of a forearm type crutch. The distance between cuff and handgrip is adjustable, as is the lower pole length. A resilient limb or bow is rigidly affixed to the lower end of the pole, with its upper attachment end being rearwardly offset from the pole. This results in a forward torque or moment when the user applies a downward force upon the crutch during use, thereby assisting the user in forward travel. The lower or distal end of the limb also absorbs shock for the crutch user when the limb contacts the underlying surface. The springback of the limb returns a considerable portion of the energy imparted by the user as weight was applied to the crutch, thereby facilitating user mobility. | 08-19-2010 |

Each positioning base has two insertions each having a limiting notch and a hook. When the positioning base engages the recess, the limiting notches combine with the limiting portions and the pin inserts into one corresponding positioning hole. When the positioning base is released from the recess, the limiting notches disengage from the limiting portions, the pin disengages from the positioning hole, and the hook combines with the limiting portion. | 12-01-2011 |
