Abstract:
Included are embodiments of a guide apparatus. In some embodiments, the guide apparatus includes a body portion, a connector housing, and a rounded connector portion. The connector housing may include a connector snap surface that is disposed on an interior surface of the connector housing. Additionally, the connector housing may define a hollow portion adjacent to the interior surface. The connector housing may be coupled to the body portion via the connector snap surface. Similarly, the rounded connector portion may be coupled to the connector housing and may removably secure to a spad that is disposed on a ceiling, such that the guide apparatus hangs substantially downward, regardless of the orientation of the spad. By hanging substantially downward, the retractable guide apparatus may more accurately identify an intended path within a mine shaft.
