Guide rail for carriage printer
View Patent ↗A printer includes a carriage and a channel for guiding the carriage along a path. The carriage includes a protrusion extending from the carriage. The channel includes a first wall and a second wall. The first and second walls are opposed to each other. The protrusion of the carriage extends between the first wall and the second wall. A first portion of the protrusion is in contact with the first wall and a second portion of the protrusion is in contact with the second wall.
1. A printer comprising:
a carriage including a protrusion extending from the carriage; and
a channel for guiding the carriage along a path, the channel including a first wall and a second wall, the first and second walls being opposed to each other, the protrusion of the carriage extending between the first wall and the second wall, a first portion of the protrusion being in contact with the first wall, and a second portion of the protrusion being in contact with the second wall; the channel further comprising a third wall connecting the first wall and the second wall.
2. The printer of claim 1 , wherein the first and second portions of the protrusion are curved.
3. The printer of claim 1 , the first wall being disposed at a first angle with respect to vertical and the second wall being disposed at a second angle with respect to vertical, wherein the first angle and the second angle are each less than 60 degrees when the carriage is disposed in a printing orientation.
4. The printer of claim 1 , the first wall being disposed at a first angle with respect to vertical and the second wall being disposed at a second angle with respect to vertical, wherein the first angle and the second angle are each less than 45 degrees when the carriage is disposed in a printing orientation.
5. The printer of claim 1 , wherein the first wall and the second wall are positioned at a non-perpendicular angle relative to each other.
6. The printer of claim 1 , wherein gravity acts as a biasing mechanism to keep the protrusion of the carriage in contact with the first and second walls of the channel.
7. The printer of claim 1 , wherein the protrusion extends from the carriage in a substantially downward direction from the carriage when the carriage is disposed in a printing orientation.
8. The printer of claim 1 , further comprising:
a lubricating medium disposed on the first and second walls in the region where the first and second portions of the protrusion contact the first and second walls of the channel.
9. The printer of claim 1 , wherein the third wall is approximately horizontal when the carriage is disposed in a printing orientation.
10. The printer of claim 1 , wherein no portion of the protrusion makes contact with the third wall.
11. The printer of claim 1 , the channel including an axis that is parallel to the path, the channel further comprising:
an extension for attaching the channel to the printer, the extension including a mounting surface that extends along a direction which is substantially parallel to the axis.
12. The printer of claim 1 , the channel including an axis that is parallel to the path, the channel further comprising:
a extension for attaching the channel to the printer, the extension and the channel including bent portions that are substantially parallel to the axis.
13. A printer comprising:
a carriage including a protrusion extending from the carriage; and
a channel for guiding the carriage along a path, the channel including a first wall and a second wall, the first and second walls being opposed to each other, the protrusion of the carriage extending between the first wall and the second wall, a first portion of the protrusion being in contact with the first wall, and a second portion of the protrusion being in contact with the second wall; wherein the carriage includes a center of gravity, and the carriage further comprising: a rotation limiting extension, wherein the rotation limiting extension and the protrusion are located on the same side of the center of gravity.
14. The printer of claim 13 , further comprising:
a rotation limiting rail including a wall against which the rotation limiting extension makes contact.
15. The printer of claim 14 , wherein the wall of the rotation limiting rail is substantially vertical when the carriage is disposed in a printing orientation.
16. The printer of claim 13 , wherein the first and second portions of the protrusion are curved.
17. The printer of claim 13 , the first wall being disposed at a first angle with respect to vertical and the second wall being disposed at a second angle with respect to vertical, wherein the first angle and the second angle are each less than 60 degrees when the carriage is disposed in a printing orientation.
18. The printer of claim 13 , the first wall being disposed at a first angle with respect to vertical and the second wall being disposed at a second angle with respect to vertical, wherein the first angle and the second angle are each less than 45 degrees when the carriage is disposed in a printing orientation.
19. The printer of claim 13 , wherein the first wall and the second wall are positioned at a non-perpendicular angle relative to each other.
20. The printer of claim 13 , wherein gravity acts as a biasing mechanism to keep the protrusion of the carriage in contact with the first and second walls of the channel.
21. The printer of claim 13 , wherein the protrusion extends from the carriage in a substantially downward direction from the carriage when the carriage is disposed in a printing orientation.
22. The printer of claim 13 , further comprising:
a lubricating medium disposed on the first and second walls in the region where the first and second portions of the protrusion contact the first and second walls of the channel.
