Definitions

• the invention relates to a container for a stack of images, ie a stack of images of the same format, essentially rectangular, especially photo prints. It comprises a housing provided with a viewing window and a housing provided parallel to the viewing window and a slide which can be pulled out of the housing parallel to the viewing window plane. Compared to the viewing window, a stand is hinged to the housing, which can be folded out or in, so that the container can optionally also be used as a stand.
• Such a container is known from US Pat. No. 4,376,348.
• the stack is cyclically rearranged by pulling out the slide and pushing it back in, for which purpose an interchangeable mechanism is accommodated in the container.
• the stand of the known container is approximately L-shaped and snapped onto the housing base by means of two joints provided at the ends of the L-legs. The locking of the fold-out position of this stand is also provided in the area of the joints.
• the housing base corners are not available for the arrangement of the joints for reasons of the structure of the interchangeable mechanism.
• the stand joint or the stand joints will then have to be placed further towards the center of the housing floor, with the result that the stand becomes shorter.
• a shorter stand is to ensure the same stability of the frame, to fold out a larger angle from the folded position and to lock it in the opened position.
• the container should also be usable as a hanging frame, which results in the requirement that the side of the container is essentially flat with respect to the window when the stand is folded.
• the latching means must accordingly be sunk inside the container, but where - so that the shifting function is not disturbed - a certain maximum level should not be exceeded either.
• a container for a stack of images of the same format, essentially rectangular, with a housing having a viewing window and a slide which can be pulled out of the housing, and with a stand which is articulated on the housing bottom opposite the window and which has stops which when the stand is folded out lock the stand by abutment against counter-stops of the housing, the stops and counter-points being arranged in the direction of the free end of the stand at a distance from the stand joint and the elements having the stop surfaces being designed and arranged in such a way that they fold when the stand is folded dodge with elastic deflection and overlap each other when the stand is folded.
• the construction according to the invention makes it possible to use a minimum of thickness (in the direction of the container depth) for the latching of the stand, the stand being able to be folded out by the necessary angle without arranging the stops too close to the articulated axis of the stand, the stand so it can snap into place without the moment load becoming too great.
• FIG. 1 shows a plan view, partially cut open and partially with the slide extended, of a container designed as an image changer.
• FIG. 2 shows the underside of the container from FIG. 1.
• Fig. 3 shows a section along the line 3-3 of Fig. 2nd
• FIG. 4 and 5 show a partial section through the bottom region of the container from FIG. 1 with the stand folded in or out.
• FIG. 6 shows a partial section in the bottom region of the container along the line 6-6 of FIG. 4.
• FIG. 7 shows a section along line 7-7 of FIG. 2.
• FIG. 8 and 9 show the stand for the container of Fig. 1 in plan view and in side view.
• the illustrated container designed as an image changer has a housing 10 consisting of an upper shell 12 and a lower shell 14 which, as shown, can be screwed or welded, snap devices or the like. are interconnected.
• the upper shell 12 has a substantially rectangular or square cutout 16 for a window 18, which is surrounded by the upper shell 12 like a mat.
• the housing 10 accommodates a slide 20 which is provided with a handle 22 and is displaceably guided in the housing 10, for which purpose the slide 20 on the handle 22 which, when the slide 20 is inserted, has corresponding recesses in the upper and lower portions ⁇ shell 12, 14 is recorded, can be detected.
• the slider 20 receives a stack of images which, when the slider 20 is inserted, is pressed in the direction of the window 18 by means of springs 24.
• a separating device which serves to separate an individual image from the image stack.
• the separating device comprises a separator 26 which is attached to the slide 20 on the side opposite the handle 22.
• a holding device is provided which retains the image isolated from the stack of images by the separating device when the slide 20 is pulled out of the housing 10 in the housing 10, while the remaining stack is pulled out of the housing 10 with the slide 20.
• the holding device comprises an adhesive coating 28 on the inside of the housing 10 facing the window 18.
• a feed device serves to feed images to the separating device. It comprises hooks 30 on the sides of the springs 24 facing the handle 22.
• the hooks 30 serve to press the images of the stack of images in a staggered manner against the separator 26 during the changing process and the last image of the stack of images in a gap between the separator 26 and to hold the adhesive coating 28, the separator 26 initially running over a jump 32 against which the last image is pressed, so that the separator 26 can pass over this last image during the start of the change process.
• the last image of the stack of images that remains in the housing 10 during the changing process is progressively raised in the direction of the window 18 by a guide device, comprising the springs 24 and further lifting springs 34, when the slide 20 is pulled out, so that when the slide 20 is reinserted it moves onto the window other side of the stack of images.
• the lower shell 14 forms a bottom portion 36 of the housing 10, which is provided with a flat projection 38, which is designed to correspond to a bevel 40, which is arranged adjacent to the cutout 16 and circumferentially thereto, so that this enables the containers to be stacked becomes.
• the flat projection 38 has an indentation 42 which extends approximately diagonally to the bottom section 36 for receiving a fold-out stand 44 which, when folded, is flush with the outer surface of the projection 38.
• a depression 46 In the edge region of the projection 38 there is a depression 46 in order to be able to engage with the fingernail and to fold out the stand 44.
• the stand 44 has an axis 48 at one end, a section 50 being angled obliquely to the interior of the housing 10 located between the stand 44 and the axis 48.
• the axis 48 is caught between an angle 52, which is formed on the recess 42, and a pan 54 on the bottom portion 36 by snapping.
• a locking device which consists of two fork-like locking ribs 56, which are formed on the stand 44 and which, when the stand 44 is folded in, each have an opening 58 in the recess 42 into the interior of the housing 10 protrude.
• the approximately triangular locking ribs 56 are slightly flared at their free ends on the sides facing away from each other.
• ribs 60 Adjacent to the locking ribs 56, ribs 60 extend over the height of the recess 42, are located with their free ends flush with the surface of the projection 38, are also in the openings 44 of the stand 44 when the stand 44 is folded in, and are in the region of their free ends Provide ends with a slope 62 directed towards the adjacent locking rib 56.
• the two locking ribs 56 are pressed towards one another while passing the inclines 62 in order to return to the normal position after overcoming this resistance caused by the ribs 60.
• the locking ribs 56 are provided laterally on the outside with facets 64, which cooperate with the bevels 62 in order to press the locking ribs 56 together.
• facets 66 are provided on their free outer edges which, after being folded out, engage the adjacent, mutually facing edges 68 at the free ends of the ribs 60 in a locked position and facilitate the folding back of the stand 44.
• the facets 64 and 66 are arranged in such a way that, when the stand 44 is folded out, when it hits the bevel 62 or when it engages with the edges 68, it runs practically parallel to it.
• Two circular segment-shaped projections 70 serve to ensure that the stand 44 falls out of its joint 52, 54 when a lateral impact occurs in the direction of the arrow 72.
• the axis 48 is also arranged under a roof 74, which on the one hand gives the joint part in the lower shell 14 additional stability and on the other hand an unimpeded one Parts that are arranged inside the housing 12 can slide over.
• a pin 76 is used to lock the stand 44 in the folded position.
• the parts of the locking device are located below a line 78, so that the functional level of the change mechanism located in the housing 10 is not adversely affected.
• the stand 44 has at its free end two bevels 80 arranged at a right angle to one another, one of which runs parallel to one side of the container and the other parallel to an adjacent side perpendicular thereto, so that the container can either be raised or Landscape format can be set up.
• 44 stiffening ribs 82 can be provided on the side of the stator facing the housing 10.
• FIGS. 10 and 11 illustrate a modification in which the stand 44, which is bent in the transition area at the edge of the projection 33 so that the contour of this transition area is continued, and continues a little further into the bottom section 36.
