Abstract
A fan housing for allowing air to circulate through a fan having rotating fan blades while serving as a safety guard. The housing includes a circumferential wall located about the fan blades. The wall is shielded to a degree sufficient to inhibit the insertion of fingers or the like into the path of the blades adjacent to the blade path and relatively more open along other parts of the wall. The fan housing also includes front and rear safety panels. The fan housing has separable portions which may be pivotally opened and closed without the use of tools for allowing ready access to the fan unit within the fan housing for cleaning and maintenance.
Claims14
A fan housing for allowing air to circulate through a fan having rotating fan blades which extend radially from a center point, the rotating fan blades forming a blade path, the housing serving as a safety guard, comprising:
- a circumferential wall located about the fan blades wherein the wall has a relatively open part and a relatively more open part, the relatively open part being located adjacent the fan blades and shielded to a degree sufficient to inhibit the insertion of fingers or the like into the path of the blades and, the relatively more open part being located along other parts of the wall not adjacent the blade path.
An improved fan housing having a frame side wall and a front panel for allowing air to circulate through a fan mounted therein which had rotating fan blades, the rotating fan blades forming a blade path, the front panel serving as a safety guard, the improved housing comprising:
- a circumferential side wall located about the fan blades wherein the wall has a relatively open part and a relatively more open part, the relatively open part being located adjacent the fan blades and shielded to a degree sufficient to inhibit the insertion of fingers or the like into the path of the blades and, the relatively more open part being located along other parts of the wall not adjacent the blade path;
- and
- means for opening and closing the front panel without the use of tools having in an open position at least one pin integral with the fan housing which acts as a hinge pin, and having in a closed position at least one pin integral with the fan housing which secures the front door to the side wall.
A fan housing for allowing air to circulate through a fan having rotating fan blades which extend radially from a center point, the rotating fan blades forming a blade path, the housing serving as a safety guard, comprising:
- a circumferential wall located about the fan blades, the wall being formed from a plurality of generally parallel circumferential wires, the wall having a relatively open central part and a first relatively more open end part on one side of the central part and a second relatively open end part on the other side of the central part, the relatively open part being located adjacent the fan blades and shielded to a degree sufficient to inhibit the insertion of fingers or the like into the path of the blades, the relatively more open end parts having a first diameter, and the relatively more open part generally parallel circumferential wires being of a different diameter than the relatively open central part;
- a front panel mounted on the circumferential wall for allowing air to circulate through the fan while serving as a safety guard;
- a rear panel mounted on the circumferential wall for allowing air to circulate through the fan while serving as a safety guard;
- means for opening and closing the front panel without the use of tools having in an open position at least one pin integral with the fan housing which acts as a hinge pin, and having in a closed position at least one pin integral with the fan housing which secures the front panel to the circumferential wall;
- and
- support means for supporting a fan motor from the fan housing.
