Transmitter mounting structure for tire condition monitoring apparatus
First Claim
1. A mounting structure for a transmitter of a tire condition monitoring apparatus arranged in a tire of a vehicle having a wheel and the wheel including a drop center and a rim formed integrally with the drop center at a predetermined angle relative to the drop center, the mounting structure comprising:
- a valve stem attachable to the rim of the wheel for charging air into the tire, the valve stem having a basal end;
a casing connected to the valve stem to house the transmitter; and
a coupling fixture for coupling the casing and the valve stem, the coupling fixture including;
a coupler coupled to the basal end of the valve stem;
an anchor for anchoring the casing; and
a connection for connecting the coupler and the anchor at an angle to one another so that the coupling fixture is resilient, with the angle between the coupler and the anchor being greater than the predetermined angle before the coupling fixture couples the casing and the valve stem to one another.

Abstract
A mounting structure for a transmitter of a tire condition monitoring apparatus that enables the transmitter to be attached to wheels having different cross sectional shapes. A wheel has a drop center and a rim formed integrally with the drop center at a predetermined angle relative to the drop center. The mounting structure includes a valve stem arranged on the rim and having a basal end. A casing houses the transmitter. A coupling fixture couples the casing and the valve stem. The coupling fixture includes a coupler coupled to the basal end of the valve stem, an anchor for anchoring the casing, and a connection for connecting the coupler and the anchor so that the coupling fixture is resilient. The angle between the coupler and the anchor is greater than a predetermined angle before the coupling fixture couples the casing and the valve stem.

10. A method for mounting a transmitter of a tire condition monitoring apparatus arranged in a tire of a vehicle having a wheel, the wheel including a drop center and a rim formed integrally with the drop center at a predetermined angle relative to the drop center, the rim having a valve hole, the method comprising:
-
preparing a valve stem for charging air into a tire, the valve stem having a basal end;
preparing a casing for housing the transmitter, the casing having a projection;
preparing a coupling fixture for coupling the casing and the valve stem, the coupling fixture including a coupler coupled to the basal end of the valve stem and having a coupling hole, an anchor for anchoring the casing, and a connection for connecting the coupler and the anchor at an angle to one another so that the coupling fixture is resilient, with the angle between the coupler and the anchor being greater than the predetermined angle before the coupling fixture couples the casing and the valve stem;
attaching the casing to the anchor of the coupler;
inserting the basal end of the valve stem through a coupling hole of the coupling fixture to couple the basal end of the valve stem to the coupling fixture with a bushing; and
attaching the valve stem to the valve hole in the rim when the projection of the casing is abutted against the drop center of the wheel by the resiliency of the coupling fixture. - View Dependent Claims (11, 12, 13)
