Description

FIELD OF DISCLOSURE

The present subject matter relates to retention devices, and more particularly to a frame for retaining a placard on a vehicle.

BACKGROUND

A panel comprising a placard having indicia thereon may be secured to a container used to carry or move different products. Such container may be one of an intermediate bulk container, a trailer, railcar, truck, tank (rail or storage), or other vehicle body, a building, or other movable or stationary item. Such indicia may be an image and/or a sequence of characters specified by a regulatory organization (e.g., the U.S. Department of Transportation, the International Maritime Organization, and the like), that identifies the contents of the container and/or whether special care should be taken during transport or storage of such contents.

Placards having particular indicia imprinted thereon associated with particular materials and placard frames that hold such panels are commercially available. The placard frame is secured to a container and a preprinted placard is removably inserted or secured to the placard frame to identify the contents of the container. For example, when the container is used to hold first contents, a first preprinted placard associated with the first contents is selected from a plurality of preprinted placards and inserted into the frame. Thereafter, when the container is used to hold second contents, the first preprinted placard is removed from the placard frame and a second preprinted placard associated with the second contents is selected from the plurality of preprinted placards and inserted into the frame.

Often, the removal and replacement of one placard with another may be problematic, in that during the removal and/or insertion process, the placard becomes cocked i.e., the side edges of the placard are moved out of a parallel condition with respect to the side members of the placard frame. Such an occurrence can cause one or more portions of the placard to be pinched between members of the placard frame and/or trapping of the placard in the placard holder. While the incidence of such a condition can be reduced by increasing the size of the placard frame that receives the placard relative to the placard (the placard size is fixed by regulatory requirements), such a solution to the problem undesirably reduces the ability of the placard frame to retain the placard reliably during transit.

SUMMARY

According to one aspect, a placard frame includes a first frame member and a second frame member spaced from the first frame member and extending therefrom at a margin. The first and second frame members and the margin define an interior space. A projection is disposed on one of the first frame member and the second frame member at a location one of at and adjacent to the margin. The projection extends into the interior space and has a cross-sectional profile comprising one of a linear taper and curved taper. A slot remote from the projection is disposed in communication with the interior space and adapted to permit sliding of a placard therethrough at least one of into and out of the interior space. The one of a linear taper and curved taper forms a shallow angle with the one of the first frame member and the second frame member on which the projection is disposed and prevents pinching or trapping an edge of the placard as the placard is slid into the placard frame.

DETAILED DESCRIPTION

Referring to FIG. 1, a frame 8 for holding a placard comprises a first or base frame member 10 and a second frame member 12 joined in any suitable fashion to or integral with the first frame member 10. For example, the second frame member 12 may be secured to the first frame member 10 by one or more of a mechanical clinching joint formed, for example, by a Tox® tool (Tox® is a registered trademark of Tox Pressotechnik GMBH & Co. KG CORPORATION of Riedstrasse 4 Weingarten, Germany D-88250). Alternatively, a clinching joint made by tooling marketed by BTM (Tog-L-Loc® Clinching), Bollhoff-Attexor (Rivclinch®), and/or Eckold may be used and/or one or more rivets, mating bolts and nuts, one or more screws, one or more welds, adhesive, etc., or combinations thereof may be used. Thus, for example, FIG. 2 illustrates a portion of a frame 8 that comprises a joint 13 formed by a Tox® tool. The frame 8 is secured in any suitable fashion, for example, by any one or more of the above-described fastening apparatus/methodologies, to an item that may comprise an intermediate bulk container (IBC), a trailer, railcar, truck, tank (rail or storage), or other vehicle body, building, or other movable or stationary item that may be used to contain and/or move different products.

It should be noted that while a single placard clip 19 and no hinges are shown, a different number of clips (or no clips) and/or one hinges and/or more other structures may be included, if desired.

Referring also to FIGS. 3 and 4, the first and second frame members 10, 12 together define a slot 20, which is preferably, but not necessarily, disposed at an upper portion of the frame 8. The slot 20 is adjacent and leads to an interior space 22. The space 22 is defined by the frame members 10, 12, which are spaced from one another at a center portion 24 of the frame 8. The second frame member 12 includes one or more side members 26a-26d and cross members 26e, 26f defining a window 28 (FIG. 1). The window 28 is preferably square or rectangular in shape, although the window 28 may have a different shape. The window 28 may be open to the outside or may have a transparent covering. In any event, an item, such as a hazardous item placard 30 (only shown in FIG. 1 in generalized form), is disposed in the space 22 and is observable through the window 28.

The placard 30 is placed in the interior space 22 by sliding same downwardly (or in another direction depending on the orientation of the frame 8) through the slot 20. Preferably, the placard 30 is sized to fit snugly in the interior space 22 so that movement of the placard 30 therein is restricted. However, the snug fit may result in binding or cocking of the placard 30 as the placard 30 is being inserted into or removed from the interior space 22. This issue is addressed in the illustrated embodiments by the providing one or more upraised portions in the form of projections 40 (visible in FIGS. 3-8) that extend into the interior space 22 from one or both of the frame members 10, 12. More specifically, in a first embodiment shown in FIGS. 3-5, one or more discontinuous upraised portions, such as portions 40a-40c extending from the first frame member 10 toward the second frame member 12, are disposed at a location at or adjacent to one or more margins, such as side margins 42a, 42b and end margin 42c, defining the interior space 22. If desired, in an alternative embodiment illustrated in FIG. 6, one or more upraised portions 40 may extend fully (or substantially fully) and continuously along the side margins 42a and 42b and end margin 42c defining the interior space 22, although the upraised portion 40 may be discontinuous and/or may extend along only a portion of the margins 42a-42c, e.g., the upraised portion 40 may comprise portions 40a, 40b extending fully or partially only along the margins 42a and 42b, as illustrated in the alternative embodiment of FIG. 7. In any event, the upraised portions 40 assist in guiding the edges of the placard 30 as the placard 30 is inserted through the slot 20 into the interior space 22 to prevent binding or cocking. Preferably, as seen in FIG. 4 in connection with the projection 40b, each of the upraised portions 40 has one or both of a smooth (i.e., non-discontinuous) cross-sectional profile or discontinuous cross-sectional profile comprising a linear taper, e.g., at portion 43, or curved taper, e.g., at portion 45, or a bump or other projection(s). Also, the upraised portions are preferably disposed at a shallow angle with respect to the remainder of the frame members 10 and 12 and do not form significant discontinuities with the frame members 10 or 12 that can result in significant pinch points that can grab the side or end edges of the placard 30 and promote seizing of the placard 30.

Referring to FIG. 8, if desired, one or more of the portions 40 may be replaced by one or more downwardly extending portions in the form of projections 50 carried by the second frame member 12 and extending into the interior space 22. Still further, one or more of the portions 40 may be replaced by one or more upraised portion(s) in the form of projection(s) 52 carried by the first frame member 10 and one or more downwardly extending portion(s) comprising the projection(s) 50 carried by the second frame member 12 in register and aligned with the upraised portion(s) 52. In any event, the projections 50 and/or 52 may be sized and shaped to fill the gaps between the members 10 and 12 at margins of the space 22 in such a manner to minimize/eliminate gaps that can catch and trap one or more edges of the placard 30.
