DESCRIPTION:
BRIEF SUMMARY
The invention relates to a container for accommodating a pile of pictures having a housing that has a viewing window for looking at the uppermost picture in the pile and having a slider member which can be pulled out of the housing parallel to the plane defined by the window. When such a container is designed as a picture changer, as described, for example, in U.S. Pat. Nos. 4,238,898, 4,238,899, 4,241,528, 4,241,529, 4,245,417, 4,259,802 and 4,376,348, the pile of pictures is rearranged cyclically by pulling the slider member out and pushing it in again. The components necessary for this function, the so-called change mechanism, requires a certain amount of space in the container, especially in front of and behind the pile in the direction of movement of the slider member. In order to prevent these parts from being seen through the window when the slider member has been pushed in, that is to say, for example, when the container is being used as a standing or hanging frame, the relevant edges of the window are substantially congruent with the visible picture, that is, at a distance from the edges of the housing parallel to them. And in order that the container still looks attractive, a suitable distance is also provided between the edges of the window perpendicular to the mentioned edges and the edges of the housing parallel thereto. In this manner the window is surrounded, passe-partout-like, by outer surface regions of the housing.
Such containers are intended primarily for photographic prints. The formats most commonly used for photographic prints are, however, relatively small in relation to the amount of space required by the change mechanism, with the result that the regions of the housing that surround the window in the manner of a passe-partout appear disproportionately wide. The problem on which the invention is based is to provide a container which is also suitable as a picture changer and in which the width of the passe-partout regions can be freely selected within wide limits with the given outer dimensions of the contour of the container.
This problem is solved by means of the features indicated in patent claim 1; the dependent claims define preferred and/or advantageous developments of this design.
The invention is explained in detail below with reference to the embodiment shown in the enclosed drawings;
FIG. 1 is a plan view of a container designed as a picture changer, in part in section and in part with the slider member withdrawn.
FIG. 2 shows sections of an upper shell for the container in FIG. 1 in a side view, partially in section.
FIG. 3 shows, in section, sections of a corner of the upper shell in FIG. 2, perpendicular to the view in FIG. 2.
FIGS. 4 and 5 show an alternative embodiment, analogously to FIG. 3.
The picture changer shown has a housing 10 which comprises an upper shell 12 and a lower shell 14 which, as shown, are connected to one another by screws or by welding, snap-fit means or the like. The upper shell 12 has a substantially rectangular or square cut-out 16 for a window 18 which is surrounded, passe-partout-like, by the upper shell 12.
The housing 10 accommodates a slider member 20 which is provided with a grip part 22 and is guided displaceably in the housing 10, for which purpose the slider member 20 can be grasped by the grip part 22 which is accommodated by corresponding recesses in the upper and lower shells 12, 14 when the slider member 20 has been pushed in. The slider member 20 accommodates a pile of pictures which, when the slider member 20 is pushed in, is pressed by springs 24 in the direction towards the window 18.
Also provided is a separating device which serves to separate an individual picture from the pile of pictures. The separating device comprises a separator 26 which is secured to the slider member 20 on the side opposite the grip part 22.
A retaining means is provided which holds the picture separated from the pile of pictures by the separating device in the housing 10 when the slider member 20 is pulled out of the housing 10, while the remainder
