Marking instrument
A tip reinforcing system that is configured to allow a user to adjust a rigidity attribute of the marking tip of a instrument, the tip reinforcing system including: a tip core cavity that is a hollow portion within a marking tip that extends axially through the marking tip, a tip reinforcing core configured to be movable within the tip core cavity in order to change the internal structure of the marking tip, and a core moving mechanism configured to be operated by a user to move the tip reinforcing core relative to the housing body of the instrument in order to adjust the level of exposure of the tip reinforcing core within the marking tip.
1 . A tip reinforcing system that is configured to allow a user to adjust a rigidity attribute of a marking tip of a marking instrument, the tip reinforcing system comprising:
a tip core cavity that extends axially through the marking tip,
a tip reinforcing core configured to be movable within the tip core cavity,
a core guiding tube configured to extend through the tip core cavity, the tip reinforcing core disposed within the core guiding tube, wherein an exterior side surface of the tip reinforcing core comprises threads that interact with a threaded surface on an interior surface of the core guiding tube, and
a core moving mechanism configured to be operated by a user to move the tip reinforcing core relative to a housing body of the marking instrument in order to adjust a level of exposure of the tip reinforcing core within the marking tip.
2 . The tip reinforcing system according to claim 1 , wherein the core moving mechanism comprises an actuator that is configured to move between an on position and an off position, wherein the on position moves the tip reinforcing core to a maximally forward position and the off position move the tip reinforcing core to a maximally rearward position.
3 . The tip reinforcing system according to claim 1 , wherein the core moving mechanism is a screw-type mechanism that is configured to move a position of the tip reinforcing core in an incremental fashion.
4 . The tip reinforcing system according to claim 1 , wherein the core moving mechanism is configured to have predefined stepped levels of exposure of the tip reinforcing core such that the user can adjust the position of the tip reinforcing core between the levels.
5 . The tip reinforcing system according to claim 1 , wherein the core moving mechanism is positioned within a rearward end of the marking instrument.
6 . The tip reinforcing system according to claim 1 , wherein the core moving mechanism is configured to slide on a side of the marking instrument in coordination with a movement of the tip reinforcing core.
7 . The tip reinforcing system according to claim 1 , wherein the core moving mechanism further comprises a spring and locking mechanism.
8 . The tip reinforcing system according to claim 1 , further comprising a plurality of tip reinforcing cores, wherein each tip reinforcing core has different rigidity from the other tip reinforcing cores.
9 . The tip reinforcing system according to claim 1 , further comprising a core guiding tube configured to extend through the marking instrument through the cavity so as to provide a hollow internal path that extends axially through the marking instrument ( 102 ) for the tip reinforcing core.
10 . The tip reinforcing system according to claim 1 , wherein the tip reinforcing core is removable and replaceable.
11 . A marking instrument comprising:
a body housing having a longitudinal axis (X), and
a marking tip that includes bristle tips or a synthetic porous material,
a tip reinforcing system according to claim 1 .
12 . The marking instrument according to claim 11 , wherein the marking tip is made from a conductive material such that the marking instrument is adapted for use in drawing software applications in devices with capacitive touchscreens.
13 . The marking instrument according to claim 11 , wherein the marking instrument is a paint brush that is configured to allow a user to use the marking tip to pick up an external pigment.
14 . The marking instrument according to claim 11 , further comprising a reservoir configured to contain a pigment, wherein the reservoir is connected to the marking tip.
15 . The marking instrument according to claim 11 , further comprising a button configured to be removable from body housing of marking instrument.
16 . The tip reinforcing system according to claim 1 , wherein the tip reinforcing core is substantially a same length as the core guiding tube.
17 . The tip reinforcing system according to claim 1 , wherein the marking tip includes an internal portion and an external portion, the external portion configured to extend out of the housing body.
18 . The tip reinforcing system according to claim 17 , wherein when the tip reinforcing core is in a first position within the tip core cavity, the core guiding tube deforms along with the external portion of the marking tip.
19 . The tip reinforcing system according to claim 1 , wherein an interior surface of the tip core cavity includes threads configured to interact with threads on an outer surface of core guiding tube.
20 . The tip reinforcing system according to claim 17 , further comprising:
a reservoir, wherein the core guiding tube and the tip reinforcing core extending longitudinally from the reservoir to the external portion of the marking tip.
