THE SETERMINAL SIDE FIXED BY BOX 12 AND PARTS 12 SETERMINAL FIXED BY BOX 12. A CORNER INCLUDING RETAINING ELEMENTS 27, 28 IN THE SHAPE OF AN ANGLE PREVENT A FALL OF THE SLIDES OUT FORWARD AND UP. THE WALLS OF BOX 12 HAVE TWO PARTS RESPECTIVELY UPPER 22 AND LOWER 11 AND HAVE A DIFFERENT THICKNESS, DISTRIBUTED OVER THEIR SURFACE; THANKS TO ITS SHRINKED SHAPE, THE UPPER WALL PART HAS A GREATER DEFORMABILITY THAN ITS LOWER PART. THE INVENTION ALLOWS EASIER PREHENSION OF THE VARIOUS SLIDE FRAMES BY HAND AND THEIR REMOVAL FROM THE MAGAZINE FORWARD AND UPWARD.

Description

2 2501386

  The present invention relates generally to

  essentially for a device forming a store-

  longitudinal file with a plurality of boxes for framed slides or the like, which has, on its underside and / or in the lower region of one of its longitudinal sides, a toothed transport batten, in which store-folder the boxes are open to two mutually adjacent sides and whose box walls are flexible and are provided bilaterally with holding, support or retaining elements,

  neighborhood or in the zone of contiguity or juxtaposition

  mutual recognition of open sides. The invention also relates to various applications and uses

  resulting from the implementation of such a device.

  German Patent No. 1 098 236 discloses a slide store-binder of the aforementioned type, which provides a means of safety against the falling of the slides outside. For this purpose, the box walls are provided, at their marginal or lateral border edges, with locking or stop chins and at least the parts of the box walls, which comprise the locking or stopping lugs, are realized from

  to be elastic transversely to their plane.

  For the increase of the elasticity or spring action, each wall of the box is further provided with a slot. Independently of the fact that, by these locking or stopping lugs, at the same time security and immobilization are also not obtained in the direction of the open side of the store-binder, the various individual box walls are relatively unstable on all their surface. Impeccable guidance of the slides, during the projection, is not

  always assured with this structure configuration.

  The invention therefore has the task of developing a longitudinal file store of the kind mentioned at the beginning, whose box walls are well made so as to be transversely elastic to

250138O

  their plan in the vicinity or in the region of the entry of the frame sent back and forth, but which nevertheless have sufficient stability to allow accurate or precise guidance of slides of different thicknesses. This problem is solved according to the invention in that the box walls have a different thickness, distributed over their surface, so that the lower part, adjacent to the transport bed, of each wall of the box slightly thickens wedge-shaped starting on the open longitudinal side, while simultaneously the upper part, diverted from the transport batt, of the box wall decreases or tapers slightly in wedge shape starting on the open longitudinal side. By this conformation can be obtained an introduction and an exit, without problem, of the slides, in which case these nevertheless have a maintenance of lateral support sufficient in

  their lower part and the chassis go-and-sees

  comes is also guided forcing both the introduction of the slides in the image or projection window and also when returning them

in the store-binder.

  To assist this guiding possibility as well

  that for easier insertion of slides and--

  according to another judicious aspect of the invention, at least a portion of each case wall may be provided, at its edge or thinner side edge, with a bevel or

  chamfer in the manner of a knife or sharp.

  So that a continuously increasing flexibility is obtained in the upper part of the box wall, the straight line of separation, determined by the different thickness of the box wall portions,

  advantageously forms an angle with the horizontal.

  According to another advantageous conformation characteristic, the upper part of each box wall has an inclined or oblique edge extending over a

2 2501386

  much of the wall width and each wall of

  case, on its associated lateral edge or correspon-

  on the open side of the box, a recess being at least in the vicinity or in the region of the upper part of this wall. The sharp decrease or clearance, resulting in this way in the upper part of each wall of the house, results not only in a

  considerable saving of material compared to the store-

  known workbook, but also greatly facilitates the extraction or removal of individual slides

  of the shop. Because the inclined or oblique edge of the

  upper part of the wall of the house does not extend over the entire wall width but protrudes, in its lower part, slightly protruding from the closed longitudinal side and that this lower part is conformed by being made of material, two neighboring cell walls

  constitute, in this zone, each additional

  forced guidance for the go-and-see chassis

  comes during his movement of entry or insertion.

  Thanks to the particular structure structure of the box walls, their thickness can however be maintained at a considerably smaller value than in the case of the so-called known unit store, so that, with respect to it, for a spacing or interval when the case walls are only slightly smaller, the loading or storage capacity of the store according to the invention is considerably increased. The invention will be better understood and other purposes, features, details and advantages thereof

  will appear more clearly on reading the description

  explanatory document which will follow with reference to the attached schematic drawings given solely by way of non-limiting example illustrating a presently preferred specific embodiment of the invention and in which: - Figure 1 shows a perspective view of a store- longitudinal file according to the invention;

2 2501385

  - Figure 2 is a cross section through the store; - Figure 3 shows a section along the section line III-III of Figure 2, on an enlarged scale; and - Figure 4 is a section along the line of

  section IV-IV of Figure 2, on an enlarged scale.

  The longitudinal file store 10, shown in FIG. 1, is made of synthetic material, for example polystyrol, and has, beneath the lower part 11 of each box wall 12, three

  parallel bottom sills 13, 13 'and 13 "between

  what are respectively provided a rectangular recess

  wide width 14 and a narrow rectangular recess 14 '.

  Contrela outer bottom sill 13, delimiting the wide recess 14, is a transport lug

  toothed gear 15 with which a not shown gear wheel meshes with

  for the transport of longitudinal magazine 10 by

  each time moving a box 16. The long-term store

  dinal is limited byteux frontal walls 17, 17 'which may comprise, in known manner, coupling means 18 for connecting another longitudinal magazine. The longitudinal magazine 10 is open upwards and on a longitudinal side before 19, while

  its rear longitudinal side 20 is closed.

  As can be seen in FIG. 2, the height of the rear longitudinal side 20 is substantially smaller than the height of the frame of a slide 21, shown here in phantom. At the lower portion 11 of the box wall 12 is connected an upper portion 22 which has an oblique or inclined edge 23 extending over a large portion of the wall width. Together with a triangular recess 24 on a lateral edge 25 of the box wall 12, associated or corresponding to the open front longitudinal side 19, we obtain, for the part

  upper 22, a greatly narrowed or diminished form.

  On their corners or angles formed by open sides,

2501385

  the box walls 12 comprise retaining elements 26 in the form of a square or L, which partially pass, by their upper horizontal branch 27, above the slides 21, so that a fall of these outside is prevented even when the shop is turned

  longitudinal 10 of 1800 around its longitudinal axis.

  The security or the immobilization of the slides 21 towards the front is ensured by the vertical branch 28 of the retaining elements 26. The longitudinal magazine 10 is thus suitable not only for projection presentation but also for preservation and in particular for transport without

  risk of spilling or spreading slides.

  The inner surfaces of the retainers 26 are slightly rounded or chamfered or angled to allow both problem-free expulsion of the slides 21 forward and also removal or removal upwards. The spacing distance or spacing interval, between two adjacent retaining elements 26, is chosen to be so small that even thin slides, for example mounted under cardboard or "Papp-slides", are maintained from

safe or reliable way.

  It emerges from sectional views according to FIGS. 3 and 4 that the box walls 12 have different thicknesses, distributed on their surface, namely: the lower part 11, adjacent to the transport strip 15, of each box wall 12, slightly thickens in the form of a wedge, starting on the open box side, while the upper part 22, diverted from the transport bed 15, from the box wall 12 decreases, tapers or tapers slightly in the shape of a wedge starting on the open box side. This results in a straight line of separation 29 forming an angle with the horizontal. The rigidity of the lower portion 11 is further enhanced by the fact that the box walls 12 pass to the closed rear side 20 by connecting thereto. Forced guidance, for the chassis vis-a-vis back and forth

$ 6,250,138

  represented during its insertion movement, is obtained by the fact that the inclined or oblique edge 23 of each case wall 12 protrudes a little, in its lower portion, beyond the closed longitudinal side 20 and thus constitutes a portion rigid guide 30 for the chassis vis-a-vis. The box walls 12 are provided here, at least partially on their thin lateral edge, with a bevel or chamfer 31 in the form of a knife or cutting edge, which also facilitates the introduction of the slides 21 and the chassis which are suitable for the comes.
