Abstract
Abstract An electrical circuit element (16) is maintained in place within the drop center (24) of a vehicle wheel (10) by encasing the circuit within a cylindrical plastic housing (14) which is formed into an arcuate shape. The housing is held in place by wires (18, 19) which are connected to the ends of an extension spring (22) which applies sufficient tension to keep the housing from moving during heavy braking or due to centrifugal force. The mounting assembly is configured to move to an out of the way position when contacted by a tire iron or by elements of a tire mounting machine to prevent damage to the circuit when a tire is mounted or demounted. In accordance with another embodiment of the invention, the circuit (16) is encased within a unitary annular member (56).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
106 words
Apparatus for mounting a tire condition monitoring element within a tire mounted on a wheel comprising a cylindrical housing formed into an arcuate shape having an inside radius substantially corresponding to the radius of the drop center portion of the wheel, and means for mounting said element to said housing, said housing including resilient means encircling said wheel and applying a sufficient tensile force to said housing to normally maintain it in contact with the surface of said drop center portion while permitting radial and lateral displacement of said housing within said drop center portion when engaged by an object inserted into the drop center portion.
Claim 2
Dependent Claim
106 words
Apparatus for mounting a tire condition monitoring element within a tire mounted on a wheel comprising a cylindrical housing formed into an arcuate shape having an inside radius substantially corresponding to the radius of the drop center portion of the wheel, and means for mounting said element to said housing, said housing including resilient means encircling said wheel and applying a sufficient tensile force to said housing to normally maintain it in contact with the surface of said drop center portion while permitting radial and lateral displacement of said housing within said drop center portion when engaged by an object inserted into the drop center portion.
Claim 3
Dependent Claim
23 words
Apparatus as claimed in claim 1 in which said housing is in the form of a closed ring formed of a resilient material.
Claim 4
Dependent Claim
105 words
Apparatus for retaining a tire condition monitoring element within a tire mounted on a wheel comprising a cylindrical housing formed into an arcuate shape having an inside radius substantially corresponding to the radius of the drop center portion of the wheel, means for mounting said element to said housing, and biasing means fixed to said housing and encircling said wheel operable to apply a sufficient tensile force to said housing to normally maintain said housing in contact with said wheel while permitting radial and lateral displacement of said housing within said drop center portion when engaged by an object inserted into the drop center portion.
Claim 5
Dependent Claim
105 words
Apparatus for retaining a tire condition monitoring element within a tire mounted on a wheel comprising a cylindrical housing formed into an arcuate shape having an inside radius substantially corresponding to the radius of the drop center portion of the wheel, means for mounting said element to said housing, and biasing means fixed to said housing and encircling said wheel operable to apply a sufficient tensile force to said housing to normally maintain said housing in contact with said wheel while permitting radial and lateral displacement of said housing within said drop center portion when engaged by an object inserted into the drop center portion.
Claim 6
Dependent Claim
20 words
Apparatus as claimed in claim 3 in which said housing comprises a cylinder formed of a relatively rigid plastic material.
Claim 7
Dependent Claim
26 words
Apparatus as claimed in claim 4, in which said biasing means comprises an extension spring having its ends operatively connected to the ends of said housing.
Claim 8
Dependent Claim
48 words
Apparatus as claimed in claim 5, including a first wire having one end connected to one end of said housing, a second wire having one end connected to a second end of said housing, and an extension spring connecting the opposite ends of said first and second wires.
Claim 9
Dependent Claim
51 words
Apparatus as claimed in claim 6, in which said spring is disposed substantially 180 degrees from said housing when said assembly is mounted on a wheel, the weight of said spring being substantially equal to the weight of said housing, whereby said apparatus does not affect the balance of said wheel.
Claim 10
Dependent Claim
26 words
Apparatus as claimed in claims 1 or 3, in which said element is an electrical circuit, and including means substantially enclosing said element within said housing.
Claim 11
Dependent Claim
33 words
Apparatus as claimed in claim 8, in which said electrical circuit includes a pressure switch, said housing including a port exposing a sensing element of said switch to the atmosphere within said tire.
