Lighted portable toilet

Abstract

A portable toilet has a cabin, a water closet in the cabin, a light-transmitting roof upwardly closing the cabin and having an outer edge, and a vent pipe projecting upward through the roof. A light fixture for the toilet has a housing adapted to fit in an installed position against an outer face of the roof and having a throughgoing hole fittable over the vent pipe and a side turned toward the roof. A light source in the housing is energizeable to emit light from the side through the roof and into the cabin. A latch formation on the housing is engageable with the rim to secure the housing to the roof.

1 . In combination, a portable toilet comprising:
 a cabin;   a water closet in the cabin;   a light-transmitting roof upwardly closing the cabin and having an outer edge; and   a vent pipe projecting upward through the roof; and an electrical light fixture having   a housing adapted to fit in an installed position against an outer face of the roof and having a throughgoing hole fittable over the vent pipe and a side turned toward the roof;   a light source in the housing and energizeable to emit light from the side through the roof and into the cabin; and   a latch formation engageable with the rim to secure the housing to the roof.   
   
   
       2 . The portable toilet defined in  claim 1  wherein the latch formations engage under the edge adjacent the pipe. 
   
   
       3 . The portable toilet defined in  claim 2  wherein the outer edge of the roof projects horizontally past a respective side wall of the cabin. 
   
   
       4 . The portable toilet defined in  claim 3  wherein the roof lies around the vent pipe on a plane inclined to the horizontal and the hole is elongated with an uphill side fitting flatly against the vent pipe the installed position. 
   
   
       5 . The portable toilet defined in  claim 1  wherein the latch formation is rigid. 
   
   
       6 . The portable toilet defined in  claim 1  wherein the housing has two relatively telescoping parts, one of the parts being formed with the hole and the other of the parts with the latch formation, the parts being relatively slidable between an open position and a closed position with the latch formation being closer to the hold in the closed position than in the open position, the latch formation being open toward the hole so that in the closed position it can grip around the roof outer edge. 
   
   
       7 . The portable toilet defined in  claim 6 , further comprising
 a lock engageable between the housing parts for locking same in the closed position.   
   
   
       8 . The portable toilet defined in  claim 1 , further comprising
 means including a photoelectric cell for inhibiting energization of the light source during daylight.   
   
   
       9 . The portable toilet defined in  claim 1 , further comprising
 means including a motion sensor for inhibiting energization of the light source except when the cabin is occupied by a user.   
   
   
       10 . The portable toilet defined in  claim 1 , further comprising
 a standalone power source in the housing for energizing the light source.   
   
   
       11 . The portable toilet defined in  claim 10  wherein the source includes an array of solar cells on an upper face of the housing. 
   
   
       12 . The portable toilet defined in  claim 10  wherein the source includes a battery in the housing. 
   
   
       13 . The portable toilet defined in  claim 1  wherein the source includes at least on light-emitting diode. 
   
   
       14 . The portable toilet defined in  claim 1  wherein the housing has a metal frame and plastic shell.
