Method and apparatus for mounting a tire pressure monitoring device
View Patent ↗A tire pressure mounting apparatus is provided including a pressure sensor for sensing the pressure in a tire. The pressure sensor has a housing. A threaded fastener is secured to the housing and forms a first valve portion. A tire valve stem projects through a first opening in a rim for holding the tire. The tire valve stem carries a second valve portion therein. The first valve portion and the second valve portion form a valve when screwed together.
1. A tire pressure monitoring device mounting apparatus comprising:
a pressure sensor for sensing the pressure in a tire, said pressure sensor having a housing;
a first valve portion comprising a valve stem and a first threaded fastening portion; and
a second valve portion connected to said housing, said second valve portion comprising a second threaded fastening portion for projecting through an opening in a rim for holding the tire, the first threaded fastening portion being engageable with the second threaded fastening portion to screw together the first and second valve portions and thereby secure the pressure sensor to the rim, said first valve portion and second valve portion when screwed together forming a valve.
2. The tire pressure monitoring device mounting apparatus of claim 1 further comprising an O-ring coupled to said first valve portion for forming an air-tight seal against the rim when said first and second valve portions are screwed together.
3. A tire pressure monitoring device mounting method comprising the steps of:
mounting a pressure sensor for sensing the pressure in a tire in a housing;
providing a first valve portion comprising a valve stem and a first threaded fastening portion;
connecting a second valve portion to the housing, the second valve portion comprising a second threaded fastening portion;
projecting the second threaded fastening portion through an opening in a rim for holding the tire; and
screwing the first valve portion and the second valve portion together to form a valve.
4. The tire pressure monitoring device mounting apparatus of claim 1 further comprising a first O-ring coupled to said first valve portion and a second O-ring coupled to said second valve portion for forming an air-tight seal against the rim when said first and second valve portions are screwed together.
5. A tire pressure monitoring device mounting apparatus comprising:
a pressure sensor for sensing the pressure in a tire, said pressure sensor having a housing;
a first valve portion comprising a valve stem and an internally threaded portion; and
a second valve portion connected to said housing, said second valve portion having an externally threaded portion for projecting through an opening in a rim for holding the tire, the internally threaded portion being engageable with the externally threaded portion to screw together the first and second valve portions and thereby secure the pressure sensor to the rim, said first valve portion and second valve portion when screwed together forming a valve.
