DESCRIPTION:
BRIEF SUMMARY
The invention relates to a storage container for a pile of sheets, especially one in which by means of a reciprocating movement of two frame parts relative to each other the pile of sheets which they accommodate can be cyclically rearranged; however, the invention is not limited to this application. Nevertheless, for the sake of simplicity, reference will be made hereinafter to a "sheet changer". The sheets may for example be photographic prints of the same format.
A sheet changer or storage container having a housing which has an upper shell provided with a viewing window for display of the uppermost sheet and has a lower shell, and having a slider member which can be pulled out of the housing parallel to the plane of the viewing window through an opening in the housing and pushed back in again and which has a front wall that when the slider member is pushed in closes the opening in the housing, is known from published applications Europe 0203155 and PCT International Applications Nos. WO 86/03018, WO 86/03019, WO 86/03022, WO 86/03026, WO 86/03028, WO 86/03029 and WO 86/03030.
The known sheet changer consists of a two-shell housing and a slider member or drawer, which can be pulled out of the housing parallel to the plane of a window inserted into the upper, or top, shell of the housing and pushed back in again. Each complete to and fro movement of the drawer effects the transfer of a sheet from one side of the pile to the other, so that after each such cycle another sheet is displayed beneath the window.
The plane of separation between the upper, or top, and lower, or bottom, shells of the housing lies approximately in the middle between the front and back of the container. The top and bottom shells each have a cut-out into which there fits a grippable portion of the slider member.
This configuration has drawbacks from the aesthetic point of view and that of manufacture.
The grippable portion of the drawer which fits into the "picture mount" of the top shell surrounding the viewing window is reduced with respect thereto by an unavoidable line of separation which spoils the appearance of this visible side of the container, and this is particularly disturbing when the container is used as a hanging or standing frame. In order to cover this at least to some extent, the top shell and the part of the drawer flush with it should be provided with the same decorative finish. If the manufacturer wishes to offer several different decorative finishes, several components of the corresponding form must be produced, stored and assembled. This complicates the logistics of manufacture.
Like the drawer, the top and bottom shells of the housing are also injection-moulded plastics parts, which must naturally be able to be unmoulded. For this reason the container has its maximum external dimensions in the region of the plane of separation between the two shells, and the shells can taper upwards or downwards, respectively, only after this plane of separation. For this reason the container looks relatively thick when seen from the front.
The problem on which the invention is based is that of constructing the container in such a way that it is aesthetically satisfying and at the same time the logistics for its manufacture are simplified even if there is a plurality of different decorative finishes.
The solution according to the invention consists in the fact that the visible side of the container is made to look like a customary picture frame, for which purpose the features referred to in connection with the above-mentioned published applications are provided.
Starting from the plane of separation near the window, the bottom shell of the housing can be constructed with a sharply tapering contour, and to the eye the container thus seems slim, since these rear portions, when seen from the front, at a large spatial angle can no longer be detected at all or are severely curtailed.
Furthermore, it is no longer necessary to match the decorative finish of the top shell and that of the drawer. Instead, the lower shell and slider memb
