## Abstract

An information handling system bezel latches to an information handling system housing with latches coupled to a slot structure that slides relative to the bezel. The slot structure has a slot through which a lock couples so that the slot structure slides relative to the lock when the lock is in an unlocked position. When the lock is in the locked position, a lock member rotates to an axis that the slot structure slides along to engage a stop formed in the bezel so that the slot structure is prevented from sliding without generating torsional forces when a sliding force is pressed against the sliding structure.

## Claims

### Claim 1

An information handling system comprising:
a housing;
a processor coupled within the housing and operable to execute instructions that process information;
a memory coupled within the housing and interfaced with the processor, the memory operable to store the instructions and information;
a bezel coupled to the housing;
a lock assembly coupled to the bezel, the lock assembly sliding along an axis between a locked position that latches the bezel to the housing and an unlocked position that releases the bezel from the housing, the lock assembly having a lock that rotates to a locked position having a member engaged against the bezel along the axis to resist the sliding without torsional force;
first and second parallel arms, each terminating at one end with a latch;
a slot structure coupled in a middle position to the first and second parallel arms opposite the latch and sized to accept the lock;
an upper rail formed in a first side of the bezel;
a lower rail formed in the first side of the bezel; and
a rail support coupled to a second side of the bezel, the upper rail, lower rail and slot structure, the rail support capturing the first and second parallel arms in a sliding relationship.

### Claim 2 (depends on 1)

The information handling system of claim 1 further comprising a pin engaged through the lock at the slot structure, the slot structure sliding relative to the pin and lock when the lock rotates to an unlocked position.

### Claim 3 (depends on 2)

The information handling system of claim 2 further comprising a latch handle coupled to the first and second parallel arms to push the slot structure to slide relative to the pin.

### Claim 4 (depends on 3)

The information handling system of claim 3 wherein the latch handle couples to the rail support to engage with the first and second parallel arms.

### Claim 5 (depends on 4)

The information handling system of claim 4 wherein the bezel comprises a outer portion and a inner portion, the rail support captured between the outer portion and the inner portion.

### Claim 6 (depends on 1)

The information handling system of claim 1 further comprising:
a lip formed in the bezel proximate the lock;
wherein the lock member engages against the lip when the lock rotates to the locked position to prevent sliding of a slot structure.

### Claim 7 (depends on 6)

The information handling system of claim 6 wherein the lip limits travel of the slot structure when the lock rotates to the unlocked position.

### Claim 8

A method for securing an information handling system, the method comprising:
latching a bezel to a housing of the information handling system;
rotating a lock of the bezel to a locked position having a lock member aligned along a sliding axis to engage against a stop position of the bezel to prevent sliding of a slot structure;
rotating the lock of the bezel to an unlocked position freeing the slot structure to slide in a slot of the slot structure along the sliding axis relative to the lock and release the latching;
coupling the slot structure to the lock with a pin inserted through a slot of the slot structure into the lock; and
sliding the slot structure relative to the lock at the slot by engagement of the pin and lock through the slot.

### Claim 9 (depends on 8)

The method of claim 8 further comprising:
engaging the slot structure with the bezel by first and second parallel arms; and
aligning the slot to accept the lock in a middle position between the first and second parallel arms.

### Claim 10 (depends on 9)

The method of claim 9 further comprising:
coupling the slot structure between first and second portions of the bezel; and
engaging the slot structure with a handle exposed exterior to the bezel and configured to translate sliding movement to the slot structure.

### Claim 11 (depends on 10)

The method of claim 10 further comprising:
moving the handle with the lock in an unlocked position; and
translating the moving to slide the slot structure relative to the lock.

### Claim 12 (depends on 11)

The method of claim 11 further comprising:
restricting sliding motion of the slot structure when the lock is unlocked by engaging the slot structure against the stop position of the bezel.

### Claim 13 (depends on 12)

The method of claim 12 further comprising:
coupling a rail support between the bezel portions;
coupling the handle to the rail support; and
sliding that slot structure against the rail support.

### Claim 14

A bezel comprising:
first and second bezel portions coupled together;
a lock assembly coupled between the first and second bezel portions, the lock assembly sliding along an axis between a locked position that latches the bezel to an information handling system housing and an unlocked position that releases the bezel from the information handling system housing, the lock assembly having a lock that rotates to a locked position having a member engaged against a stop formed in the first bezel portion along the axis to resist the sliding without torsional force;
first and second parallel arms, each terminating at one end with a latch; and
a slot structure coupled in a middle position to the first and second parallel arms opposite the latch and sized to accept the lock;
an upper rail formed in the first bezel portion;
a lower rail formed in the first bezel portion; and
a rail support coupled to the second bezel portion, the upper rail, lower rail and the slot structure, the rail support capturing the first and second parallel arms in a sliding relationship.

### Claim 15 (depends on 14)

The bezel of claim 14 further comprising a pin engaged through the lock at the slot structure, the slot structure sliding relative to the pin and lock when the lock rotates to an unlocked position.
