DESCRIPTION:
BRIEF SUMMARY
The invention relates to a container for a pile of sheets essentially of like format. A container of this type, designed as a sheet changer, is disclosed in U.S. Pat. No. 4,376,348. The known container comprises a housing with a viewing window from which a slider member carrying the pile of sheets can be pulled out and pushed back in again in a direction parallel to the plane of the viewing window. Each time the slider member is moved back and forth a sheet is removed from one end of the pile and put back at the other end of the pile, so that by the relative movements of the housing and slider member the pile is cyclically rearranged. For aesthetic reasons and also in order to be able to use the container as a stand-up or hanging frame, the outline of the container is, apart from rounded-off parts, intended to be essentially of a closed-rectangular shape. On the other hand, the user must be able to grasp the slider member. Therefore, the known container has moulded onto the slider member a grip part which fits-in inwards towards the viewing window from a slider member front end which is flush with one edge of the housing. The grip part has at the top and at the bottom a grip plate or wall, the outer faces of which are flush with the surrounding housing faces, and these housing faces have cut-outs or recesses complementary with the grip plates. From the front wall of the slider member side-pieces extend into the container which are joined to each other by an inner transverse wall, designed in the case mentioned as a separator bar. The pile of sheets, of which the front edge bears against the grip part and is supported by the bottom grip plate, rests on these side pieces. When the slider member is in the fully withdrawn position, the transverse edge of the pile facing the housing is supported only laterally by the side-pieces of the slider member.
With sheets that are particularly bowed, especially with photographic prints, when the slider member is pushed in the centre of the lower sheets in the pile may therefore strike the extreme edge of the grip plate recess, as a result of which the sheets are damaged, and this applies similarly to the upper end of the pile in the case of bowing in the opposite direction. At the upper end of the pile there is, of course, less risk, because the top grip plate is much narrower than the bottom one and consequently also the sheets are checked over a greater width by the surrounding housing top faces. This problem could be solved by simply extending the housing and slider member in the withdrawal direction, but this results in a large unwieldy container and also in the use of more material, which is undesirable in mass-produced articles of this type made of injection-moulded plastics.
In accordance with the invention, therefore, another solution to this problem is provided by a container for a pile of sheets, essentially of like format, with a housing which has a viewing window exposing to view the uppermost sheet in the pile, and with a slider member, which can be pulled out of the housing parallel to the plane of the window, having a front wall essentially flush with one edge of the housing, which wall is joined by side-pieces to a slider member rear wall, as well as a grip arrangement that fits-in in the direction of the window from the front wall and comprises a grip top plate or wall and a grip bottom plate or wall, the outer faces of which are essentially flush with the surrounding outer faces of the housing, and having at least one housing part that extends parallel to one of the grip plates and, when the slider member is in the pushed-in state, is covered by this grip plate.
The invention is described in detail in the following with reference to the accompanying drawings.
FIG. 1 is a longitudinal section of a first embodiment
