Abstract

A latch assembly is provided for securing a power supply assembly to a motorized vehicle that facilitates attachment and detachment of the power supply assembly. The latch assembly includes a securing member for releasably coupling the latch assembly to a fixed member on the vehicle. A joining member rotates the securing member in order to engage and release the fixed member. A handle assembly is coupled to the joining member for activation of the latch assembly.

Claims

1. A latch assembly for securing and releasing a power supply assembly to a vehicle comprising:

a securing member pivotably coupled to the power supply assembly;

a joining member having a first end and a second end, the first end coupled to the securing member; and

a handle for lifting and carrying the power supply assembly, the handle operatively coupled to the second end of the joining member;

wherein a force applied to the handle causes the joining member to rotate the securing member and release the power supply assembly from the vehicle.

2. The latch assembly as set forth in claim 1, wherein the securing member is U-shaped

3. The latch assembly as set forth in claim 1, wherein the handle further comprises:

a handle portion slidably mounted to the power supply assembly;

a connecting member coupled to said handle portion;

a connecting plate coupled to said connecting member; and

a resilient member, the resilient member residing between the connecting plate and the power supply assembly supplying a return force upon slideable movement of the handle portion.

4. The latch assembly as set forth in claim 3, wherein the joining member is coupled to the connecting plate via a tab portion containing an opening into which the joining member projects.

5. The latch assembly as set forth in claim 1, wherein the securing member is adopted to engage a fixed member on the vehicle for securing the power supply assembly to the vehicle.

7. The latch assembly as set forth in claim 1, wherein the joining structure has a curved end and a straight end.

8. The latch assembly as set forth in claim 1, wherein the joining structure is coupled to said handle assembly via an opening in a connecting tab having a front surface.

6. The latch assembly as set forth in claim 6, further comprising a resilient member coupled to the securing member, wherein the resilient member urges the securing member towards the fixed member on the vehicle upon engagement of the power supply assembly with the vehicle.

9. A power driven vehicle comprising:

a frame;

a plurality of wheels supported on the frame,

a seat for the user of the vehicle to sit on,

a seat support for supporting the seat on the frame,

a drive motor for propelling the vehicle,

a power supply assembly removably affixed to the frame and retaining a portable battery supply for operating the drive motor, the power supply assembly comprising

a moveable handle for lifting the assembly,

an enclosure for retaining the battery supply, and

a joining member operatively coupled to the handle, and

a fixed member on the frame, the joining member operatively coupling the power supply assembly to the frame and releasing the coupling upon activation by the handle.

10. A power driven vehicle as claimed in claim 9, further comprising a tiller supported on the frame, the tiller operatively coupled to at least one of the wheels for steering the vehicle.

11. A power driven vehicle as claimed in claim 9 wherein the power supply assembly further comprises resilient means for directing the joining member normally into an engagement position with the fixed member.

12. A power driven vehicle as claimed in claim 9 wherein the fixed member is secured to the seat post.

13. A power driven vehicle as claimed in claim 12 wherein the power supply assembly wraps around the seat post and electrically connects to the drive motor upon the assembly being affixed to the frame.

14. A power driven vehicle as claimed in claim 9 wherein the power supply assembly further comprises:

a connecting member, and

a connecting plate coupled to the handle and moveable therewith,

the connecting member pivotably retained on the connecting plate and coupled to the joining member,

a lifting movement of the handle causing a corresponding movement of the plate, a pivoting of the connecting member along with the plate, and a releasing motion of the joining member.

15. A power driven vehicle as claimed in claim 14, wherein the power supply assembly further comprises a resilient member acting between the plate and the enclosure to normally position the handle in the down position and, in turn, position the joining member in an engagement position with the fixed member.
