Abstract

An information handling system includes a base portion with a moveable first latch member. A display portion is moveable relative to the base portion. A first side of the display portion includes a first side latch engagement member and a second side of the display portion includes a second side latch engagement member. The display portion includes a first latch member actuator that is operable, in response to positioning the first side of the display portion adjacent the base portion, to move the first latch member adjacent the first side latch engagement member to resist movement of the display portion relative to the base portion and, in response to positioning the second side of the display portion adjacent the base portion, to move the first latch member adjacent the second side latch engagement member to resist movement of the display portion relative to the base portion.

Claims20

Dependent claims

A latching system, comprising:

a first component including a first latch member that is moveable relative to the first component;
a second component moveable relative to the first component, wherein a first side of the second component includes a first side latch engagement member and a second side of the second component includes a second side latch engagement member;
and
a second latch member moveably coupled to the second component and including a first latch member actuator that is operable:
in response to positioning the first side of the second component adjacent the first component, to move the first latch member such that the first latch member is operable to engage the first side latch engagement member to resist movement of the second component relative to the first component, wherein the second latch member is movable in either of two directions to prevent the first latch member from engaging the first side latch engagement member such that the second component may be moved relative to the first component;
and
in response to positioning the second side of the second component adjacent the first component, to move the first latch member such that the first latch member is operable to engage the second side latch engagement member to resist movement of the second component relative to the first component, wherein the second latch member is movable in either of two directions to prevent the first latch member from engaging the second side latch engagement member such that the second component may be moved relative to the first component.

4 more elements

An information handling system, comprising:

a base portion that houses a processor and a memory coupled to the processor, wherein the base portion includes a first latch member that is moveable relative to the base portion;
a display portion that includes a display screen and that is moveable relative to the base portion, wherein a first side of the display portion includes a first side latch engagement member and a second side of the display portion includes a second side latch engagement member;
and
a second latch member that is moveably coupled to the display portion in two directions, and includes a first latch member actuator that is operable:
in response to positioning the first side of the display portion adjacent the base portion, to move the first latch member such that the first latch member is operable to engage the first side latch engagement member to resist movement of the display portion relative to the base portion;
and
in response to positioning the second side of the display portion adjacent the base portion, to move the first latch member such that the first latch member is operable to engage the second side latch engagement member to resist movement of the display portion relative to the base portion
wherein movement of the second latch member in either of the two directions is operable to prevent engagement of the first latch member and either of the first side latch engagement member and the second side latch engagement member.

5 more elements

A method for latching a convertible information handling system (IHS), comprising:

providing an IHS comprising a base portion and a display portion that is moveable relative to the base portion, wherein the display portion includes a first side and a second side that is located opposite the display portion from the first side;
latching the display portion to the base portion in a first IHS mode, wherein the latching comprises:
moving the first side of the display portion adjacent the base portion such that a first latch member actuator in the display portion moves a first latch member in the base portion into a latching position;
and
resisting the movement of the display portion relative to the base portion through the engagement of a first side latch engagement member in the display portion and the first latch member in the base portion;
and
latching the display portion to the base portion in a second IHS mode, wherein the latching comprises:
moving the second side of the display portion adjacent the base portion such that the first latch member actuator in the display portion moves the first latch member in the base portion into the latching position;
and
resisting the movement of the display portion relative to the base portion through the engagement of a second side latch engagement member in the display portion and the first latch member in the base portion
unlatching the display portion from the base portion in either the first IHS mode or the second IHS mode by:
moving the second latch member in either of two directions.
