Abstract
Abstract The present invention relates to an impingement shield (sometimes known as a mud guard or a splash fender) for a truck, trailer, tractor, or a similar vehicle. The disclosure teaches that such a shield may be mounted in a manner that the stresses to which it is usually subjected are transferred to a mechanical structure designed to absorb these stresses. The disclosed structure provides a fail safe arrangement that is long lived and inexpensive.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
245 words
Apparatus for mounting an impingement shield, comprising: a housing; a support rod adapted to have an impingement shield supported therefrom; said support rod having a pressure plate affixed to said support rod to define a rod/plate assembly; said pressure plate being positioned within said housing; means for resiliently orienting said support rod in a normally horizontal orientation whereby said support rod and said supported shield may move under the influence of a disturbing face and for resiliently reorienting said support rod and said supported shield when said disturbing force is removed; said housing having an aperture therein; said support rod being positioned to project out of said housing through said aperature; said resilient orienting means comprising at least one compression spring positioned in said housing, with one end of said spring positioned to press against a surface of said plate, and the other end of said spring positioned to press against a wall of said housing; said housing having at least one collar like end piece having said aperture; said plate being positioned in said housing with the outer surface of said plate abutting the inner surface of said collar like end piece, with said support rod projecting out of said housing through said aperture; said compression spring urging said outer surface of said plate against said inner surface of said end piece for causing said support rod to project outwardly through said aperture of said collar like end piece in a normally horizontal orientation.

The combination of claim 1, wherein said housing has a second end piece; said other end of said spring being positioned to press against said second end piece.
Claim 4
Dependent Claim
268 words
Apparatus for mounting an impingement shield, comprising: a housing; a support rod adapted to have an impingement shield supported therefrom; said support rod having a pressure plate affixed to said support rod to define a rod/plate assembly; said pressure plate being positioned within said housing; means for resiliently orienting said support rod in a normally horizontal orientation whereby said support rod and said supported shield may move under the influence of a disturbing force and for resiliently reorienting said support rod and said supported shield when said disturbing force is removed; said housing having an aperture therein; said support rod being positioned to project out of said housing through said aperture; said resilient orienting means comprising at least one compression spring positioned in said housing, with one end of said spring positioned to press against a surface of said plate, and the other end of said spring portioned to press against a wall of said housing; said aperture being located in one of the longitudinal walls of said housing; said plate being positioned in said housing with one surface of said plate toward one end of said housing, and the other surface of said plate toward the other end of said housing, said resilient orienting means comprising a second compression spring positioned in said housing with one end of said second spring positioned to press against the other surface of said plate, and the other end of said spring positioned to press against the other wall of said housing; said resilient orienting means causing said support rod to project outwardly through said aperture in a normally horizontal orientation.
