Abstract
The marker rotation and retention device maintains multiple markers together, making it easier for a user to maintain the markers as a set. Optionally, the marker rotation and retention device includes angular rotation stops that are able to hold the angular position of specific marker with respect to its neighbors. This allows the user to easily withdraw and replace a specific marker by keeping the entrance to the cap exposed.
Claims18
A marker retention device comprising:
- a shaft;
- a plurality of markers;
- each marker of the plurality of markers having a cap;
- each marker of the plurality of markers having a body;
- a splined connection between the shaft and each marker cap;
- the splined connection allowing each marker cap to rotate with respect to the shaft;
- the splined connection snapping each marker cap to set angular positions with respect to the shaft;
- whereby a user rotates the cap to a desired position, the cap is held in the desired position until again rotated by the user.
