Display panel mounting systems

1. A display panel mounting system comprising:

a plate comprising a plate opening, a first vertical alignment hole, and a second vertical alignment hole that is aligned with the first vertical alignment hole; and

an adjustment device comprising:

a body comprising a receiver, the body configured to be received within the plate opening; a sleeve received within the body;

a coupler comprising a slot that receives the receiver such that the coupler is coupled to the body; and

a nut coupled to the body such that the sleeve is repositionable within the body when the nut is coupled to the body,

wherein the body further comprises a vertical alignment slot that is configured to be aligned with the first vertical alignment hole and the second vertical alignment hole when the body is received within the plate opening.

2. The display panel mounting system of claim 1 , wherein:

the plate further comprises:

a first horizontal alignment hole; and

a second horizontal alignment hole that is aligned with the first horizontal alignment hole; and

the body further comprises a horizontal alignment slot that is configured to be aligned with the first horizontal alignment hole and the second horizontal alignment hole when the body is received within the plate opening.

3. The display panel mounting system of claim 2 , wherein the body is configured such that the vertical alignment slot is configured to be aligned with the first vertical alignment hole and the second vertical alignment hole when the horizontal alignment slot is aligned with the first horizontal alignment hole and the second horizontal alignment hole.

4. The adjustment device of claim 1 , further comprising a display panel fastener that is configured to be coupled to a display panel;

wherein the sleeve comprises a sleeve opening that is centered on an axis; and

wherein the coupler comprises a coupler opening that is configured to receive the display panel fastener such that the axis extends through the display panel fastener when the display panel fastener is received within the coupler opening.

5. The adjustment device of claim 4 , further comprising a surface fastener;

wherein the sleeve opening is configured to receive the surface fastener;

wherein the receiver comprises an opening;

wherein the slot is configured to be positioned in the opening such that the receiver is received within the slot and removed from the opening such that the receiver is removed from the slot; and

wherein the axis extends through the opening.

6. The adjustment device of claim 1 , wherein the nut is repositionable relative to the body independently of the sleeve and independently of the coupler.

7. A display panel mounting system comprising: a plate comprising:

a first plate opening;

a second plate opening;

a first vertical alignment hole; and

a second vertical alignment hole that is aligned with the first vertical alignment hole;

a first adjustment device comprising:

a first coupler comprising a first slot;

a first body comprising a first receiver that is configured to be received within the first slot, the first body configured to be received within the first plate opening, and a first vertical alignment slot that is configured to be aligned with the first vertical alignment hole and the second vertical alignment hole when the first body is received within the first plate opening; and

a first sleeve received within the first body and threadably coupled to the first body; and

a second adjustment device comprising:

a second coupler comprising a second slot;

a second body comprising a second receiver that is configured to be received within the second slot, the second body configured to be received within the second plate opening, and a second vertical alignment slot that is configured to be aligned with the first vertical alignment hole and the second vertical alignment hole when the second body is received within the second plate opening; and

a second sleeve received within the second body and threadably coupled to the second body.

8. The display panel mounting system of claim 7 , wherein:

the first receiver has a first opening; and

the first slot is configured to be positioned in the first opening such that the first receiver is received within the first slot and removed from the first opening such that the first receiver is removed from the first slot.

9. The display panel mounting system of claim 8 , wherein:

the first adjustment device further comprises:

a display panel fastener that is configured to be coupled to a display panel; and

a surface fastener;

the first sleeve comprises a sleeve opening that is centered on an axis;

the first coupler comprises a coupler opening that is configured to receive the display panel fastener such that the axis extends through the display panel fastener when the display panel fastener is received within the coupler opening;

the sleeve opening is configured to receive the surface fastener; and

the axis extends through the first opening.

10. The display panel mounting system of claim 7 , wherein: the first sleeve is selectively repositionable within the first body; and the second sleeve is selectively repositionable within the second body independently of the first sleeve.

11. The display panel mounting system of claim 7 , wherein:

the first adjustment device further comprises a first nut that is threadably coupled to the first body such that the first body is disposed between the first nut and the first sleeve; and

the first sleeve is repositionable within the first body when the first nut is coupled to the first body.
