ARTICLE MOUNTING AND HANDLING METHOD AND APPARATUS

摘要

An article mounting and handling arrangement is provided for use with an enclosure to allow access to and replacement of the articles in a position removed from the operating environment. The arrangement is especially adapted for fuses and other electrical devices. Accordingly, the arrangement for use with fuses pro-vides access to the fuses in a position disconnected from an associated circuit and to provide connection of the fuses to the associated circuit in an inaccessible position. The fuse mounting and handling arrangement is mounted with respect to the enclosure for translation along a predetermined direction between a first, accessible position outside the enclosure and a second position with the fuses being within the enclosure. The fuse mounting and handling arrangement is also pivotally mounted with respect to an axis parallel to the direction of translation. The fuses are connected into the circuit through appropriate contacts by pivoting the fuse mounting and handling arrangement about the axis from the second position to a third position. In one particular application, one side of the fuses is selectively connected to respective switched contacts. In that application, an interlock arrangement is provided to prevent pivoting of the fuses between the second and third positions when the switch contacts are closed to the fuse contacts. The fuse mounting and handling arrangement also includes apparatus to prevent pivoting ofthe fuses when the arrangement is between the first and second positions and to prevent translation when the fuses are pivoted between the second and third positions. The arrangement also includes wall members that provide a barrier to prevent access into the enclosure when the fuses are in the first, second or third position.
