Abstract
A mounting apparatus using a sliding mechanism for easy insertion and removal of insertable units includes a supporting bracket and a sliding mechanism. The sliding mechanism includes an outer rail, a middle rail, an inner rail, a latching unit, and a locking unit. The latching unit includes first and second guiding portions on the inner rail, first and second positioning members slidably mounted to the middle rail, and third and second guiding portions on the outer rail. The locking unit includes a locking member at end of the inner rail and a locking portion on the middle rail to correspond to the locking member.
Claims20
A sliding mechanism comprising:
- an outer rail;
- a middle rail slidably mounted to the outer rail;
- an inner rail slidably mounted to the middle rail;
- a latching unit comprising:
- a first guiding portion defined on the inner rail;
- a second guiding portion defined on the inner rail;
- a first positioning member slidably mounted to the middle rail;
- a second positioning member slidably mounted to the middle rail;
- a third guiding portion defined on the outer rail;
- and
- a fourth guiding portion defined on the outer rail;
- and
- a locking unit comprising:
- a locking member rotatably mounted to an end of the inner rail;
- and
- a locking portion defined on the middle rail and corresponding to the locking member;
- wherein
- when the locking member is rotated to an unlocking position, where the locking member unlocks the locking portion, and when the inner rail slides along an installing direction until the first guiding portion is resisted by the first positioning member and the second guiding portion is resisted by the second positioning member, the first positioning member is latched by the third guiding portion and the middle rail is prevented from sliding relative to the outer rail;
- and
- wherein when the locking member is rotated to an unlocking position, where the locking member unlocks the locking portion, and when the inner rail slides along an uninstalling direction opposite to the installing direction, the second positioning member is latched by the second guiding portion, the inner rail is prevented from sliding relative to the middle rail, and the inner rail drives the middle rail to slide relative to the outer rail until the second positioning member is resisted by the fourth guiding portion, at which point the fourth guiding portion drives the second positioning member to be released by the second guiding portion, and the inner rail is released to slide and uninstalled from the middle rail and the outer rail;
- when the locking member is rotated to a locking position, where the locking member locks the locking portion, and when the inner rail slides along the installing direction, the inner rail drives the middle rail to slide together until the first positioning member is latched by the third guiding portion and the middle rail is prevented from sliding relative to the outer rail;
- and
- when the locking member is rotated to the unlocking position, where the locking member locks the locking portion, and when the inner rail slides along the uninstalling direction, the middle rail is prevented from sliding relative to the outer rail, the inner rail slides to be uninstalled from the middle rail and the outer rail.

- and
- wherein when the locking member is rotated to an unlocking position, where the locking member unlocks the locking portion, and when the inner rail slides along an uninstalling direction opposite to the installing direction, the second positioning member is latched by the second guiding portion, the inner rail is prevented from sliding relative to the middle rail, and the inner rail drives the middle rail to slide relative to the outer rail until the second positioning member is resisted by the fourth guiding portion, at which point the fourth guiding portion drives the second positioning member to be released by the second guiding portion, and the inner rail is released to slide and uninstalled from the middle rail and the outer rail;
- when the locking member is rotated to a locking position, where the locking member locks the locking portion, and when the inner rail slides along the installing direction, the inner rail drives the middle rail to slide together until the first positioning member is latched by the third guiding portion and the middle rail is prevented from sliding relative to the outer rail;
- and
- when the locking member is rotated to the unlocking position, where the locking member locks the locking portion, and when the inner rail slides along the uninstalling direction, the middle rail is prevented from sliding relative to the outer rail, the inner rail slides to be uninstalled from the middle rail and the outer rail.
