Abstract
A retaining device for improving the functionality of placard holders when the placard holder is subject to transient atmospheric conditions. The retaining device includes a member used in conjunction with a placard holder to more fully secure a placard with the placard holder when transient atmospheric conditions are encountered. The retaining device may be adapted to use with many designs of placard holders, including, but not limited to, U.S. Department of Transportation approved hazardous material information placard holders.
Claims24
A system for restricting placard movement comprising:
- a. a placard holder;
- and
- b. a substantially planar member forming an opening, wherein the substantially planar member has an out-of-plane bend, and wherein the substantially planar member is inside the placard holder.
A method for restricting placard movement comprising:
- a. inserting a substantially planar member between a placard and a first surface of a placard holder, wherein the substantially planar member has an out-of-plane bend;
- b. engaging the substantially planar member with the first surface of the placard holder;
- c. engaging the substantially planar member with the placard;
- and
- d. urging the placard against a second surface of the placard holder.

A retaining device for retaining a placard in a placard holder comprising:
- a. A substantially planar member, wherein the substantially planar member forms an opening, and has an out-of-plane bend, and wherein the substantially planar member urges the placard against the placard holder.
A placard holding device for displaying a placard upon a vertical planar surface comprising:
- a. a back frame member adapted to be mounted upon the vertical planar surface and including a plurality of adjoining back frame peripheral edges;
- b. a front frame member having a flat surface portion enclosing an open window area, the flat surface portion including a plurality of adjoining front frame peripheral edges enclosing the open window area, with the number of the front frame edges corresponding with the number of the back frame edges;
- c. fastening means for mounting the front frame member on the back frame member and including an upstanding lip integral with the back frame member and extending perpendicularly along all but one of the back frame edges, the one back frame edge comprising a rear smooth edge, a groove integral with the front frame member and extending along all but one of the front frame edges, the one front frame edge comprising a front smooth edge, the groove symmetrically disposed for co-extensive engagement with the upstanding lip when the front frame member is mounted on the back frame member;
- d. an interior placard holding pocket formed intermediate the back frame member and the flat surface portion when the front frame member is mounted on the back frame member, the placard holding pocket peripherally enclosed by the upstanding lip along all but the rear smooth edge and including an access slot formed intermediate the front and rear smooth edges;
- the improvement comprising;
- e. a substantially planar member, wherein the substantially planar member forms an opening, and has an out-of-plane bend, and wherein the substantially planar member urges a placard against at least a portion of the placard holding device selected from the group consisting of the back frame and the front frame.

A placard holding device for displaying a placard upon a vertical planar surface comprising:
- a. a back frame permanently affixed to a surface;
- b. a front frame member having a flat surface portion enclosing an open window area, the flat surface portion including a plurality of adjoining front frame peripheral edges enclosing the open window area;
- c. fastening means for mounting the front frame member on the back frame member and including an upstanding lip integral with the back frame member and extending perpendicularly along all but one of the back frame edges, the one back frame edge comprising a rear smooth edge, a groove integral with the front frame member and extending along all but one of the front frame edges, the one front frame edge comprising a front smooth edge, the groove symmetrically disposed for co-extensive engagement with the upstanding lip when the front frame member is mounted on the back frame member;
- d. an interior placard holding pocket formed intermediate the back frame member and the flat surface portion when the front frame member is mounted on the back frame member, the placard holding pocket peripherally enclosed by the upstanding lip along all but the rear smooth edge and including an access slot formed intermediate the front and rear smooth edges;
- the improvement comprising;
- e. a substantially planar member, wherein the substantially planar member forms an opening, and has an out-of-plane bend, and wherein the substantially planar member urges a placard against at least a portion of the placard holding device selected from the group consisting of the back frame and the front frame.
