I claim the ornamental design for the hanger device, as shown and described.
FIG. 1 is a front elevational view of the hanger device with the back elevational view being identical except for smaller holes shown in FIGS. 2 and 3;
FIG. 2 is a front, side perspective view of the hanger device, the opposite side being identical except for the smaller holes shown in FIG. 3; and,
FIG. 3 is a side perspective view thereof, with the opposite side being identical.
The broken line showing of a partial surface is included for the purpose of illustrating environment and forms no part of the claimed design.
