Chalk holding devices for bicycles, scooters and skateboards

1. A chalk holding device for attachment to a bicycle, wherein the bicycle has a wheel and an axle with a first end and a second end, the chalk holding device comprising:

a chalk-receiving member for receiving chalk therein;

first and second arms extending from the chalk-receiving member towards the axle, the first arm having a first axle cup for receiving a first end of the axle and the second arm having a second axle cup for receiving a second end of the axle,

wherein the first axle cup is connected to the first arm by a ball and socket joint, such that the first axle cup pivots relative to the first arm in an infinite number of directions, and wherein the first axle cup has an axis,

wherein the second axle cup is connected to the second arm by a ball and socket joint, such that the second axle cup pivots relative to the second arm in an infinite number of directions, and wherein the second axle cup has an axis,

wherein the first arm has a first end and the second arm has a second end, wherein the first and second ends are moveable into a plurality of positions each defined by a distance between the first and second ends, and wherein the axis of the first axle cup and the axis of the second axle cup are able to be aligned with one another in the plurality of positions.

2. The chalk holding device of claim 1 , wherein the first and second arms are made of a material that is resilient, such that the resiliency of the material provides a bias force to bias the first and second axle cups towards one another.

3. The chalk holding device of claim 1 , wherein the first and second axle cups provide a secure, but non-permanent connection to the first and second axle ends.

4. The chalk holding device of claim 1 , wherein no tools are required to attach the device to or detach the device from the bicycle.

5. The chalk holding device of claim 1 , further including a roller proximate the chalk-receiving member and which contacts a riding surface when chalk has been substantially expended, so as to reduce damage to the device from the riding surface when chalk has been substantially expended.

6. The chalk holding device of claim 5 , wherein the roller does not contact the riding surface when a sufficient amount of chalk is available, such as when a new piece of chalk has been properly inserted into the chalk-receiving member.

7. A chalk holding device for attachment to a bicycle, wherein the bicycle has a wheel and an axle with a first end and a second end, the chalk holding device comprising:

a chalk-receiving member for receiving chalk therein;

first and second arms extending from the chalk-receiving member towards the axle, the first arm having a first axle cup for receiving a first end of the axle and the second arm having a second axle cup for receiving a second end of the axle, wherein the first axle cup and the second axle cup each have an open end and a closed end,

wherein the first axle cup is connected to the first arm by a ball and socket joint, such that the first axle cup pivots relative to the first arm in an infinite number of directions, and wherein the second axle cup is connected to the second arm by a ball and socket joint, such that the second axle cup pivots relative to the second arm in an infinite number of directions.

8. The chalk holding device of claim 7 further including a first magnet positioned within the first axle cup and a second magnet positioned within the second axle cup.

9. The chalk holding device of claim 7 , wherein the first arm has a first end and the second arm has a second end, wherein the first and second ends are moveable into a plurality of positions each defined by a distance between the first and second ends, and wherein the axis of the first axle cup and the axis of the second axle cup are able to be aligned with one another in the plurality of positions.

10. The chalk holding device of claim 7 , wherein the first and second arms are made of a material that is resilient, such that the resiliency of the material provides a bias force to bias the first and second axle cups towards one another.

11. The chalk holding device of claim 7 , wherein the first and second axle cups provide a secure, but non-permanent connection to the first and second axle ends.

12. The chalk holding device of claim 7 , wherein no tools are required to attach the device to or detach the device from the bicycle.

13. The chalk holding device of claim 7 , further including a roller proximate the chalk-receiving member and which contacts a riding surface when chalk has been substantially expended, so as to reduce damage to the device from the riding surface when chalk has been substantially expended.

14. The chalk holding device of claim 13 , wherein the roller does not contact the riding surface when a sufficient amount of chalk is available, such as when a new piece of chalk has been properly inserted into the chalk-receiving member.

15. A chalk holding device for attachment to a bicycle, wherein the bicycle has a wheel and an axle with a first end and a second end, the chalk holding device comprising:

a chalk-receiving member for receiving chalk therein;

first and second arms extending from the chalk-receiving member towards the axle, the first arm having a first axle cup for receiving a first end of the axle and the second arm having a second axle cup for receiving a second end of the axle, wherein the first axle cup and the second axle cup each have an open end and a closed end; and,

a first magnet positioned within the first axle cup and a second magnet positioned within the second axle cup.

16. The chalk holding device of claim 15 , further including a roller proximate the chalk-receiving member and which contacts a riding surface when chalk has been substantially expended, so as to reduce damage to the device from the riding surface when chalk has been substantially expended.

17. The chalk holding device of claim 16 , wherein the roller does not contact the riding surface when a sufficient amount of chalk is available, such as when a new piece of chalk has been properly inserted into the chalk-receiving member.

18. The chalk holding device of claim 16 , wherein the first axle cup is connected to the first arm by a ball and socket joint, such that the first axle cup pivots relative to the first arm in an infinite number of directions, and wherein the second axle cup is connected to the second arm by a ball and socket joint, such that the second axle cup pivots relative to the second arm in an infinite number of directions.

19. A chalk holding device for attachment to a bicycle, wherein the bicycle has a wheel and an axle with a first end and a second end, the chalk holding device comprising:

a chalk-receiving member for receiving chalk therein;

first and second arms extending from the chalk-receiving member towards the axle, the first arm having a first axle cup for receiving a first end of the axle and the second arm having a second axle cup for receiving a second end of the axle, wherein the first axle cup and the second axle cup each have an open end and a closed end; and,

a roller proximate the chalk-receiving member and which contacts a riding surface when chalk has been substantially expended, so as to reduce damage to the device from the riding surface when chalk has been substantially expended.

20. The chalk holding device of claim 19 , wherein the roller does not contact the riding surface when a sufficient amount of chalk is available, such as when a new piece of chalk has been properly inserted into the chalk-receiving member.
