The cleaning mechanism 212 comprises a cleaning head 214 similar to the cleaning head 118 of holster 100. However, unlike the cleaning head 118 of holster, which is rotatably coupled to the support member 106, the cleaning head 214 is slidably coupled to the support member 204 adjacent the interior surface 206. An actuator 216 is coupled to the cleaning head 214 to allow the cleaning head 214 to be slid up and down the support member in order to clean a surface, or portion thereof, of the device when it is in the holster 200.
The actuator 216 may be attached to the cleaning head 214 by an attachment 218 that surrounds both external sides 220a, 220b of the support member 206. Although not depicted in FIG. 2A or 2B the support member 206 may include upper and lower stops in order to limit the movement of the cleaning mechanism 212. The attachment 218 may provide a frictional fit with the support member, in order to resist movement of the cleaning mechanism 212. The actuator 216 can move the cleaning head up and down as depicted by the arrow in FIG. 2B.
FIGS. 3A and 3B depict a side view and front view of a schematic of a still further illustrative holster. The holster 300 includes a housing 302 that is similar to the housing 102; however, the support member 304 of the housing 302 includes an annular aperture 306 similar to the aperture described with regards to FIGS. 1A and 1B. The support member 304 further includes two narrow elongated apertures 308 on either side of the annular aperture 306. The holster 300 with the annular aperture 306 and the elongated apertures 308 allows the cleaning mechanism 310 to both rotate and slide. Similar to the holster 100, the holster 300 includes a cleaning head 312 coupled to the support member 304 adjacent the interior surface of the support member 304. An actuator 314 is coupled to the cleaning head 312 by an attachment 316 that passes through the apertures 306, 308.
