WHEELCHAIR TRANSPORTER
The present invention is a device adapted to transport wheelchairs. The device comprises a body, a motor driven wheel coupled to the body, and a hitch mechanism coupled to the body. The hitch mechanism includes a first wheelchair engagement member displaceable relative to rest of the hitch mechanism.
1 . A device for transporting a wheelchair, the device comprising:
a body;
a motor driven wheel coupled to the body;
a wheelchair engaging hitch mechanism; and
a system for positively engaging the hitch mechanism with the wheelchair.
2 . The device of claim 1 , wherein the system includes a first member operably coupled to the hitch mechanism and a second member that receives the first member.
3 . The device of claim 2 , wherein the second member binds with the first member to positively engage the hitch mechanism.
4 . The device of claim 3 , wherein the first member is a rod and the second member is a bracket selectively pivotal into and out of binding engagement with the rod.
5 . The device of claim 4 , wherein the bracket includes an opening through which the rod extends, the rod binding with an edge of the opening when the bracket and rod are in binding engagement.
6 . The device of claim 4 , wherein the system includes a spring that biases the bracket into contact with the rod.
7 . The device of claim 6 , wherein the system includes a system release that overcomes the bias of the spring and pivots the bracket out of binding engagement with the rod.
8 . A device for transporting a wheelchair, the device comprising:
a body;
a motor driven wheel coupled to the body;
a hitch mechanism for engaging the wheelchair and including a wheelchair engagement member; and
a locking mechanism for locking the hitch mechanism in positive engagement with the wheelchair.
9 . The device of claim 8 , wherein the locking mechanism includes a first member and a second member, and the first and second members can be placed in engagement with each other to lock the hitch mechanism in positive engagement with the wheelchair, and the first and second members can be disengaged to allow the hitch mechanism to be disengaged from the wheelchair.
10 . The device of claim 9 , wherein the engagement between the first and second members is a result of the first and second members binding with each other.
11 . The device of claim 9 , wherein the first member is received by the second member.
12 . The device of claim 11 , wherein the first member extends through the second member via an opening in the second member.
13 . The device of claim 11 , wherein the first member is longitudinally extendable through the second member.
14 . The device of claim 11 , wherein the second member pivots into and out of binding engagement with the first member.
15 . The device of claim 14 , wherein the locking mechanism further includes a spring that biases the second member into binding engagement with the first member.
16 . The device of claim 11 , wherein the first member is a rod and the second member is a bracket pivotal relative to the rod.
17 . A device for transporting a wheelchair, the device comprising:
a body;
a motor driven wheel coupled to the body; and
a wheelchair hitching mechanism coupled to the body; and
means for locking the hitching mechanism in positive engagement with the wheelchair.
18 . The device of claim 17 , wherein the means for locking includes means for releasing the means for locking.
19 . A method of transporting a wheelchair, the method comprising:
approaching the wheelchair with a powered wheelchair transporter;
engaging the wheelchair with a hitch mechanism of the transporter; and
causing the engagement between the hitch mechanism and the wheelchair to be a positive engagement.
20 . The method of claim 20 , wherein causing the positive engagement includes creating a bind between a first member and a second member.
