Abstract
Abstract A clip and mounting system utilizing such a clip designed to adhesively mount devices to a surface, such as a windshield. The system includes a mounting member adapted to be slid over and clamped to a base plate member which is bonded to the surface. The system includes spring means which permits differential expansion between the members without significantly altering the clamping load between the members and the stress on the adhesive bond.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
179 words
A system for mounting devices to a primary workpiece including a base plate member having one surface adapted to be adhesively secured to the primary workpiece through an adhesive bonding layer, opposing side edges of the base member including shoulder surface means in spaced relationship to the said one surface, a mounting member adapted to be slidably positioned over the base plate, the mounting member including lip portions extending inwardly from the opposite side edges thereof to underlie the shoulder surface means when associated therewith, the opposing lip portions and shoulder surface means forming a first set of opposing clamping surfaces, the means to clamp the mounting member being adapted to bear against a predetermined region of the base plate and thereby forming a second set of opposing clamping surfaces, spring means positioned between at least one set of opposing clamping surfaces and adapted to relieve the stress on the adhesive bonding layer when the system is mounted on the primary workpiece as a result of the clamping pressure between the two members as well as preloading the system.
Claim 2
Independent Claim
179 words
A system for mounting devices to a primary workpiece including a base plate member having one surface adapted to be adhesively secured to the primary workpiece through an adhesive bonding layer, opposing side edges of the base member including shoulder surface means in spaced relationship to the said one surface, a mounting member adapted to be slidably positioned over the base plate, the mounting member including lip portions extending inwardly from the opposite side edges thereof to underlie the shoulder surface means when associated therewith, the opposing lip portions and shoulder surface means forming a first set of opposing clamping surfaces, the means to clamp the mounting member being adapted to bear against a predetermined region of the base plate and thereby forming a second set of opposing clamping surfaces, spring means positioned between at least one set of opposing clamping surfaces and adapted to relieve the stress on the adhesive bonding layer when the system is mounted on the primary workpiece as a result of the clamping pressure between the two members as well as preloading the system.
Claim 3
Dependent Claim
80 words
The mounting system as claimed in claim 1 of the type wherein the base plate member and mounting member have different coefficients of expansion causing changes in the clamping pressure between the two elements subsequent to positionment and clamping together wherein the base plate member has a recess formed therein, and includes a bottom wall adapted tO be bonded to the primary workpiece, side wall portions upstanding from the bottom wall including outwardly extending flanges forming said shoulder surface means.
Claim 4
Dependent Claim
14 words
The mounting system of claim 2 wherein the base plate member is channel shaped.
Claim 5
Dependent Claim
24 words
The mounting system in accordance with claim 2, wherein the bottom wall of the base plate member is substantially surrounded by upstanding wall portions.
Claim 6
Dependent Claim
51 words
The mounting system in accordance with claim 2, wherein the spring means includes a struck-up portion with the extremities thereof integral with the bottom wall and including an intermediate segment bulged upwardly from the bottom wall and adapted to be resiliently compressed by clamping means when a device is associated therewith.
Claim 7
Dependent Claim
31 words
The mounting system as claimed in claim 1 wherein the base plate member and mounting member include abutment means to limit the sliding movement of the mounting member in one direction.
Claim 8
Dependent Claim
43 words
The mounting system as claimed in claim 1 wherein the means to clamp the mounting member includes a set screw extending through the mounting member into engagement with the base plate serving to clamp the clip portions and the shoulder surface means together.
Claim 9
Dependent Claim
50 words
The mounting system in accordance with claim 7 wherein the set screw bears against the spring means formed in the base plate to resiliently accommodate changes in the clamping pressure between the mounting member and the base plate wherein the stress on the adhesive bond line may remain substantially uniform.
Claim 10
Dependent Claim
41 words
The mounting system in accordance with claim 7 wherein the base plate member carries adhesive means on said one surface, said one surface further including the spring means in the form of a struck-up portion positioned intermediate the shoulder surface means.
Claim 11
Dependent Claim
22 words
The mounting system in accordance with claim 7 wherein the spring means is provided between the lip portions and shoulder surface means.
Claim 12
Dependent Claim
22 words
The mounting system in accordance with claim 10 wherein the spring means is a struck-up tab formed in the shoulder surface means.
