Definitions

  • This type of cassette has the disadvantage that when an information carrier is inserted for the first time and later each time the information carrier is changed, the cassette must be removed from its place of installation, that it must be turned over to the rear, and after removing several fasteners, generally at least four fasteners , the rear wall must be removed from the frame before the space for the information carrier on the inside of the cover plate is accessible. After inserting an information carrier, the rear wall must be reinserted. Before the fasteners for the permanent connection of all parts can then be reattached, it must first be checked whether the information carrier is correctly seated viewed from the front of the cassette and whether it has not slipped when inserting the rear wall.
  • the known cassettes have the further disadvantage that the information carrier can only be inserted from the rear and therefore the rear wall must necessarily be removable, because otherwise the information carrier cannot be accommodated between the cover plate and the rear wall.
  • the frame is limited to the edge regions of the cassette and, to a certain extent, it only represents a frame for the cover plate and the rear wall, it being only more or less loosely connected to these flat parts.
  • These flat parts contribute little or nothing to the dimensional stability of the cassette.
  • Such cassettes therefore have less torsional rigidity, the simpler and lighter the frame.
  • the corner connection only has a relatively low strength. If the information carrier is changed frequently, these corner connections can loosen and finally even loosen.
  • the fasteners usually require a certain installation space, which must be taken into account in the dimensions of the frame, in particular its depth. Because of the limited installation space, the fasteners are often difficult to handle, be it when loosening or when inserting or both. Sometimes the fasteners require the additional use of any tools when removing and / or inserting.
  • the invention specified in claim 1 has for its object to provide a cassette for information carriers, in which the insertion of the information carrier and changing the information carrier is easier and faster than with the known cassettes.
  • the cover plate Characterized in that there are extensions on the cover plate, the clearance between them is smaller than the outer dimension of the frame assigned to them, the extensions can be pushed onto the relevant end faces of the frame with elastic deformation, after which they become effective under the effect of the restoring force of their elastic deformation the Place the end faces of the frame and clamp the cover plate on the frame using the opposing forces on both sides. As a result, the cover plate can be detached from the frame using a force opposite the clamping force of the cover plate and can also be put back on the frame. So there is no longer any need to insert loose parts into the corresponding molded parts of the frame.
  • the frame no longer has to be removed from its mounting location, for example from a wall, if the information carrier is either to be attached for the first time or an existing information carrier is to be exchanged for another.
  • the information carrier With the cover plate removed, the information carrier can be placed from the front on the frame and / or on its rear wall. The information carrier can thus be aligned at the same time when it is created. Since the information carrier is placed with its back on the frame and / or on the rear wall, adhesives can be used on this side of the information carrier, which is not visible from the front, so that the information carrier remains in its correct position even when it is very much in relation to the frame has small dimensions and therefore it cannot be held in place when the cover plate is attached.
  • the cassette In the event that any adhesive cannot be used when the information carrier is placed on the frame and / or on the rear wall and it cannot be held down due to its very small dimensions, the cassette must be removed from the installation site and face up a more or less horizontal surface. When the cover plate is attached, the information carrier which has already been created always remains visible, so that there is constant control over its correct position. The cassette does not need to be picked up until it is fully assembled to return it to its location.
  • a certain form fit with a kind of snap action is added to the frictional engagement between the clamping sections of the cover plate and the frame, which results in an additional holding force between the cover plate and the frame.
  • information carriers which were folded in the initial state and are then to be accommodated in the unfolded state in the cassette can also be kept smooth and flat. Due to the greater clamping force of this cover plate, the information carrier is held in place with a greater frictional force, so that it does not slip even when the cassette is exposed to shocks during its handling or during transport from one place to another.
  • the support plate for the information carrier no longer forms a separate part. This eliminates any Guide elements and / or holding elements that are otherwise required to guide and hold the support plate in the correct position on the frame. As a result, both the manufacture is made easier and cheaper, and the weight of the frame is reduced compared to the multi-part embodiment.
  • the combination of the frame in the narrower sense with the support plate gives the frame a considerably greater dimensional stability than if these two parts were formed separately. As a result of the greater connection rigidity, the cassette maintains its flat basic shape even with larger dimensions than is the case with frames with an inserted rear wall.
  • a lateral guide is created for the cover plate in both directions, through which the cover plate can be attached to the frame in the correct position without special intervention and without special attention and it no longer requires alignment work in which Information carrier could slip.
  • the exact guidance of the cover plate relative to the frame also promotes the aesthetic effect of the cassette.
  • the cassette 10 has a frame 11 and a transparent cover plate 12.
  • the frame 11 consists of a single piece. It is made from a flat sheet metal blank, generally from a light metal sheet blank. 5 and 6, the frame 11 has a support plate 13 which forms the core of the frame 11. On the vertical side edges 14 and 15, one side wall 16 and 17, respectively, is bent at a right angle towards the rear of the cover plate 13. In a similar manner, a lower end wall 21 and an upper end wall 22 are folded on the two horizontal side edges 18 and 19 towards the rear of the cover plate 13. This would give the frame 11 a box-like shape.
  • each of the two end walls 21 and 22 there is a further surface section 23 and 24, which is again beveled relative to the associated side wall, so that it is aligned at least approximately parallel to the support plate 13.
  • These surface sections 23 and 24 serve as support or neck strips with which the cassette 10 can be attached to support elements which protrude slightly from the cassette 10 at the point of attachment, for example on a wall surface.
  • These support elements are expediently hook-shaped or provided with a head which is larger than the adjoining shaft of the support element, so that the upper support strip 23 or 24 has a secure hold thereon.
  • the information “perpendicular” and “horizontal” refer to the orientation of the rectangular cassette 10 in portrait format which can be seen in FIG. 1 and which represents the more common type of application.
  • holding elements can be clamped into the space behind the support strips 23 and 24, which provide a possibility of hanging the cassette by a connecting element between the two holding elements in the form of a strip or in the form of a cord or chain.
  • the cover plate 12 is made from a transparent material, and preferably from a cold-deformable transparent plastic, such as is sold under the trademark "Macrolon".
  • These terminal strips 27 and 28 form an angle with the cover plate 12 which is less than 90 °.
  • the end walls 21 and 22 of the frame 11 with its support plate 13 enclose an angle which is less than 90 ° (FIGS. 2 and 5).
  • the end walls 21 and 22 Due to this inclination of the end walls 21 and 22 relative to the normal plane to the support plate 13, the end walls 21 and 22 form a recess with respect to their front edge, which at the same time forms the lower side edge 18 and the upper side edge 19 of the support plate 13.
  • the cover plate 12 is in the initial state, i.e. in the free state removed from the frame 11 (FIG. 4), formed as a section of a cylindrical surface, the surface lines of which are aligned parallel to the two side edges 25 and 26 to which the terminal strips 27 and 28 connect.
  • the cylinder surface is raised on the side of the terminal strips 27 and 28.
  • the curvature of the cylindrical shape of the cover plate 12 is selected such that the cover plate lies against the support plate 13 of the frame 11 as flat as possible in the direction of its two clamping strips 27 and 28, namely when it with its clamping strips 27 and 28 are snapped or engaged on the end faces 21 and 22 (FIG. 2).
  • This clamping force results from the fact that at least the inner edges 29 and 30 of the terminal strips 27 and 28, however, also a section of the Terminal strips 27 and 28 themselves, have a clear distance which is smaller than the outer distance of the front edges 18 and 19 of the end walls 21 and 22.
  • the elastic restoring force in the cover plate 12 and in its terminal strips 27 and 28 has the effect that the terminal strips 27 and 28 then lie against the end walls 21 and 22.
  • the clear distance between the inner edges 29 and 30 is not only smaller than the outer distance of the front edges 18 and 19, but also somewhat smaller than the outer distance of their contact points on the end walls 21 and 22 to ensure that the elastic deformation of the cover plate 12 and its clamping strip 27 which occurs for the sliding of the clamping strips 27 and 28 over the front edges 18 and 19 on the frame 11 remains within the elastic deformability of these parts and does not result in a plastic deformation which causes the Clamping force would be reduced.
  • the angle of inclination of the end walls 21 and 22 with respect to the normal plane to the cover plate 13 should also be selected.
  • the side walls 16 and 17 of the frame 11 continue beyond its end walls 21 and 22.
  • the guide tabs 31 and 32 formed by these extensions serve to guide the cover plate 12 laterally, as can be seen from FIGS. 2 and 3.
  • the guide tabs 31 and 32 extend at least into the tear area of the terminal strips 27 and 28. For aesthetic reasons, it is expedient to extend the guide tabs 31 and 32 to at least the outside of the clamping strips 27 and 28, so that, viewed from the side, they are completely hidden behind the guide tabs 31 and 32, as can be seen from FIG. 1.
  • the support strips 23 and 24 can have, for example, a V-shaped notch in the center of their free edge, by means of which the cassette can be centered more easily on a single stationary support element.
  • this notch or in addition to it openings, in particular in the form of a keyhole, can also be provided in the support strips in order to be able to securely hang the cassette 10 on a support with a head.
  • a strip-shaped extension can be connected to the terminal strip 22 at the top, to which the support strip 24 only connects. The increased distance of the support strip 24 from the front of the support surface 13 then automatically results in an inclined position of the entire cassette 10.
