Claim 4
Dependent Claim
67 words
An apparatus which removably supports a cover to a vertical surface on a base structure according to claim 1 wherein said hanger is of U-shaped configuration having a second vertical portion parallel and spaced from said first mentioned vertical portion, and wherein said second vertical portion is attached to the base vertical surface and wherein said spring vertical leg is attached to said hanger second vertical portion.
Claim 5
Independent Claim
165 words
An apparatus which removably supports a cover to the vertical surface of a base structure, comprising: a hanger having a horizontal portion, the inner end of which is secured to the base vertical surface, the horizontal portion having an opening therein; a spring of inverted V-shape configuration having a vertical leg supported on the base structure vertical surface and having an integral angular leg extending downwardly and away from the plane of the base structure vertical surface, the upper portions of the spring vertical and angular legs being received in said opening in said hanger; and a bracket having a horizontal portion, the inner end of which is affixed to the cover, and a downwardly extending vertical portion integrally extending from the horizontal portion outer end, whereby said bracket is secured to said hanger by inserting the bracket vertical portion in said opening in said hanger horizontal portion and displacing the cover downwardly, the bracket vertical portion engaging and resiliently displacing said spring angular leg.
Claim 6
Independent Claim
165 words
An apparatus which removably supports a cover to the vertical surface of a base structure, comprising: a hanger having a horizontal portion, the inner end of which is secured to the base vertical surface, the horizontal portion having an opening therein; a spring of inverted V-shape configuration having a vertical leg supported on the base structure vertical surface and having an integral angular leg extending downwardly and away from the plane of the base structure vertical surface, the upper portions of the spring vertical and angular legs being received in said opening in said hanger; and a bracket having a horizontal portion, the inner end of which is affixed to the cover, and a downwardly extending vertical portion integrally extending from the horizontal portion outer end, whereby said bracket is secured to said hanger by inserting the bracket vertical portion in said opening in said hanger horizontal portion and displacing the cover downwardly, the bracket vertical portion engaging and resiliently displacing said spring angular leg.
