Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
188 words
A splash guard or mud guard for vehicles comprising an upper section, and a lower section pivotally secured to the upper section, the lower edge of the upper section and the upper edge of the lower section each having a pair of cylindrical hollow hinge barrels, the hinge barrels of one section interfitting with the hinge barrels of the other section to provide an axial opening therethrough, and a pair of axially aligned hollow cylindrical sleeves positioned within the axial opening with each sleeve extending from a hinge barrel of one section into an adjacently positioned hinge barrel of the other section, with the inner ends of the cylindrical sleeves being secured against rotation within inner hinge barrels of opposite sections, thereby pivotally securing the upper and lower sections together, and one of a pair of oppositely wound helical springs positioned in each cylindrical sleeve with the inner end of each sleeve being secured against rotation within its respective sleeve, and with the outer ends of the springs being secured against rotation within outer hinge barrels of opposite sections, and means to adjust the tension of the springs.
Claim 2
Dependent Claim
188 words
A splash guard or mud guard for vehicles comprising an upper section, and a lower section pivotally secured to the upper section, the lower edge of the upper section and the upper edge of the lower section each having a pair of cylindrical hollow hinge barrels, the hinge barrels of one section interfitting with the hinge barrels of the other section to provide an axial opening therethrough, and a pair of axially aligned hollow cylindrical sleeves positioned within the axial opening with each sleeve extending from a hinge barrel of one section into an adjacently positioned hinge barrel of the other section, with the inner ends of the cylindrical sleeves being secured against rotation within inner hinge barrels of opposite sections, thereby pivotally securing the upper and lower sections together, and one of a pair of oppositely wound helical springs positioned in each cylindrical sleeve with the inner end of each sleeve being secured against rotation within its respective sleeve, and with the outer ends of the springs being secured against rotation within outer hinge barrels of opposite sections, and means to adjust the tension of the springs.
Claim 3
Dependent Claim
18 words
A splash guard according to claim 1, wherein the upper section has means for securement to a vehicle.
Claim 4
Dependent Claim
30 words
A splash guard or mud guard according to claim 1 wherein the springs are under tension, the tension of one spring being opposite to the tension in the other spring.
Claim 5
Dependent Claim
68 words
A splash guard according to claim 1 wherein the inner ends of the springs are secured against rotation within their respective sleeves, and the inner ends of the sleeves are secured against rotation within respective inner hinge barrels of opposite sections by pins or rivets passing through holes provided in the inner hinge barrels and the sleeves, and through loops provided on the inner ends of the springs.
Claim 6
Dependent Claim
36 words
A splash guard according to claim 4, wherein the inner ends of the sleeves are provided with a series of circumferentially spaced openings to selectively receive the pins or rivets passing through the inner hinge barrels.
Claim 7
Dependent Claim
88 words
A splash guard or mud guard for vehicles according to claim 1 wherein loops formed in outermost ends of the springs are received within inwardly opening slots provided in cylindrical plugs positioned within the outer ends of the outer hinge barrels, the outer surfaces of the plugs having slots enabling rotation thereof to adjust the tension of the springs and to receive pins or rivets passing through the outer hinge barrels to secure the plugs against rotation with respect to their respective hinge barrels after the tension adjustment.
Claim 8
Dependent Claim
116 words
A splash guard for vehicles comprising an upper section and a lower section pivotally secured together, the lower edge of the upper section and the upper edge of the lower section having hollow cylindrical hinge barrels in parallel adjacent relationship with an oppositely wound helical spring positioned longitudinally within each hinge barrel, one end of one spring being secured against rotation within its hinge barrel with the opposite end of the other spring being secured against rotation within its hinge barrel, and end caps closing adjacent ends of the parallel hinge barrels, the ends of the springs not secured within the hinge barrels being secured to the end caps to hold the end caps in position.
Claim 9
Dependent Claim
116 words
A splash guard for vehicles comprising an upper section and a lower section pivotally secured together, the lower edge of the upper section and the upper edge of the lower section having hollow cylindrical hinge barrels in parallel adjacent relationship with an oppositely wound helical spring positioned longitudinally within each hinge barrel, one end of one spring being secured against rotation within its hinge barrel with the opposite end of the other spring being secured against rotation within its hinge barrel, and end caps closing adjacent ends of the parallel hinge barrels, the ends of the springs not secured within the hinge barrels being secured to the end caps to hold the end caps in position.
