Abstract

A steering column locking device. More specifically, a steering column locking device for golf carts, and the like.

Claims (35)

1. A steering column comprising:

a. A sleeve portion having an open area extending the length of said sleeve portion;

b. a steering shaft portion disposed within said sleeve portion adapted to rotate within said sleeve portion and having at least one terminal end portion extending beyond said sleeve portion;

c. a main body portion fixed about said sleeve portion having

i. a central aperture extending through said main body adapted to receive said sleeve portion;

ii. a groove about said central aperture extending partially through said main body;

iii. a locking aperture extending through said main body and extending into said groove;

iv. a locking mechanism extending through said locking aperture so as to allow all or some portion of said locking mechanism to extend through said groove, with such locking mechanism adapted to be reversibly removed;

d. a second body portion having

i. a perimeter wall, a bottom end, and a top end;

ii. at least one side opening extending partially or completely through said perimeter wall and positioned so as to allow said locking mechanism of said main body portion to extend into said at least one side opening;

iii. said bottom end having a portion extending into said groove of said main body portion, said bottom end being adapted to rotate with respect to said main body portion between an unlocked position wherein said locking aperture and said at least one side opening are not aligned and a locked position wherein said locking aperture and said at least one side opening are aligned; and

iv. said top end having an opening.

2. The steering column according to claim 1 wherein said opening of said top end of said second body portion is shaped to receive said terminal end portion of said steering shaft portion and is fixed to said terminal end portion so as to cause said second body portion to rotate along with the rotation of said steering shaft portion.

3. The steering column according to claim 1 wherein said terminal end portion of said steering shaft has one or more splines and said opening of said top end of said second body portion is shaped so as to receive the splined terminal end portion so as to cause said second body portion to rotate along with the rotation of said steering shaft portion.

4. The steering column according to claim 1 wherein said top end of said second body portion comprises a removable portion that includes said opening of said top end.

5. The steering column according to claim 1 wherein said central aperture is defined by at least one removable portion wherein said main body portion is shaped so as to hold said at least one removable portion within the main body portion.

6. The steering column according to claim 1 wherein said severable main body portion comprises a first portion and a second portion wherein said first portion is fixed to said second portion.

7. The steering column according to claim 1 wherein said terminal end portion of said steering shaft has one or more splines and second body portion is fixed to an adaptor having an aperture shaped so as to receive the splined terminal end portion so as to cause said second body portion to rotate along with the rotation of said steering shaft portion.

8. A locking system comprising:

a. a severable main body portion having

i. a central aperture extending through said main body;

ii. a groove about said central aperture extending partially through said main body;

iii. a locking aperture extending through said main body and extending into said groove;

iv. a locking mechanism extending through said locking aperture so as to allow all or some portion of said locking mechanism to extend through said groove, with such locking mechanism adapted to be reversibly removed;

b. a second body portion having

i. a perimeter wall, a bottom end, and a top end;

ii. at least one side opening extending partially or completely through said perimeter wall and positioned so as to allow said locking mechanism of said main body portion to extend into said at least one side opening;

iii. said bottom end having a portion extending into said groove of said main body portion, said bottom end being adapted to rotate with respect to said main body portion between an unlocked position wherein said locking aperture and said at least one side opening are not aligned and a locked position wherein said locking aperture and said at least one side opening are aligned; and

iv. said top end having an opening.

9. The locking system according to claim 8 wherein said wherein said opening of said top end is shaped to receive a terminal end portion of a rotatable steering shaft and is fixed to said terminal end portion so as to cause said second body portion to rotate along with the rotation of said terminal end portion.

10. The locking system according to claim 8 wherein said terminal bore is shaped so as to receive a splined terminal end portion of a rotatable column so as to cause said second body portion to rotate along with the rotation of said terminal end portion.

11. The locking system according to claim 8 wherein said top end of said second body portion comprises a removable portion that includes said opening of said top end.

12. The locking system according to claim 8 wherein said central bore is defined by at least one removable portion wherein said main body portion is shaped so as to hold said at least one removable portion within the main body portion.

13. The locking system according to claim 8 wherein said severable main body portion comprises a first portion and a second portion wherein said first portion is fixed to said second portion.
