Description

147Λ11

The invention relates to an assembly set of the type specified in the preamble of claim 1 *.

Such assemblies can be used for a variety of purposes e.g. as toys, for the manufacture of buildings of 5 different kinds, for decoration objects, e.g. for the manufacture of mobiles, and in the advertising industry e.g. for the production of poster collections or display stands, at which last possible pressure on the plates can increase the advertising value of the stands.

In prior art such assemblies, such as those e.g.

is known from DE-PS 860.020 and GB-PS 1.39 ^ 020, both the plates and the connecting discs have edge slots, and the discs are brought into engagement with the plates perpendicular thereto by causing a disc slot to grip the plate, at the inside of a 15 edge slit therein, while the edge slit is similarly caused to grip the disk at the interior of its edge slit. This provides a relatively good control of the disc and plate relative to each other and since each plate is usually brought into engagement with several connecting discs, which can either serve as feet 20 or connect the plate to another plate, a relatively rigid structure can be obtained in all cases, as long as the discs are not exposed to forces extending in the plates across the plate edge. However, to ensure this control, it is necessary that the overlap between a disc and a plate be relatively long, so that the plate's available e.g. for inscription or pictures the area of the plate is reduced significantly in relation to the total area of the plate. Furthermore, the slots at the edge of the plate cause a considerable weakening thereof, so that, especially in connection with larger plate assemblies, there may be a danger of bending of the plates, usually made of cardboard or cardboard, which in itself has a low strength. , which is also the case if the sheets are made of thin metal sheets.

In addition, the discs are exposed to forces extending across the plate edge, e.g. when attempting to lift a plate assembly alone into a single plate or hanging plates in superposed connecting discs, which are appropriately held in place, the plates will seek to pull away from the connection discs so that the plate joint is separated. This danger is particularly pronounced if plates and / or connecting discs have been used several times, so that the slots have expanded and only 5 to a small extent exert plate pressure against the plate or disc with which the slot engages.

This latter disadvantage is admittedly remedied by e.g. from US Pat. Nos. 3-56 ^ .758 known plate assembly, in which plates and connecting discs are not distinguished, but only 10 plates are used. At this, two teeth extending towards each other into the slot are formed at each end of the edge slot, and in each plate a hole is formed for each edge slot and at a distance from its inner end very close to the length of the slot, in which one with the plate in Intervening second plate at its 15 abrasive teeth can intervene. Although the teeth themselves must be described as weak, the fact that with each wear joint there are two sets of tooth engagement causes the joint to become somewhat resistant to wear in the wear direction. On the other hand, such an assembly causes the overlap length between the two plates to be even greater than at the aforementioned known plate assemblies, so that in practice no exploitable plate area becomes available.

The object of the invention is to provide a plate assembly of the kind in question which, due to a short overlap length, enables the obtaining of large available plate areas without weakening the plates, and yet ensures a good control of plate and disc among themselves. and a secure plate-to-plate retention even in the wear length direction.

According to the invention this is achieved by the design of the characterizing part of claim 1. In this case, only the connecting discs are designed with slots, which is why the plate strength is not reduced. A connecting disc to be connected to a plate can be inserted with an edge slot over its non-slotted edge until the nose of the disk edge slot engages with a plate opening. Thereafter, due to its length and thus relatively large control areas, the nose will not only ensure the holding of the connecting disc in position perpendicular to the plate, ie. take over the function which, in the prior art assemblies of the type concerned, is performed by the plate edge slit about the disc behind the gripping portion of its longitudinal slot, but also effectively prevent an extraction of the disc from the plate and an unintentional tilt across it. However, since the disc is of a rigid but resilient resilient material, the fact that the slot itself is closed by the nose cannot prevent the insertion of the disc, since the disc during its insertion can be tilted to take a small angle of the plate, and the nose due to the resilience of the material is twisted so that a sufficiently large opening is provided for the disc to be inserted when · o.

over the plate. When the nose / up to the plate opening, it will, by twisting the disc, by itself try to engage the opening. Similarly, the connecting disc can later be easily released from the plate by turning the disc perpendicular to the plane of the plate, whereby the nose can be tilted upwardly of the opening, so that the disc in its twisted position can be easily pulled out.

According to the invention, it may be advantageous if the configuration is further as set out in claim 2. This not only makes it easier to achieve that the nose safely engages in a plate opening, but further it can be caused by slanting, exposed due to the slope edge. grip the plate edge so that only by twisting the disc itself across 25 own plane can the sliding limiting disc portions away from each other, so that the insertion of the disc over the plate can be made easily and simply, regardless of the disc edge slot is close to closed .

The invention will be explained in more detail below with reference to the drawing, in which: FIG. 1 is an axonometric view of a plank assembly made by means of a plate set according to the invention; FIG. 2 is an exterior view of a connection disc belonging to the plate set, FIG. 3 shows a similar embodiment of a connection disc, and FIG. k a section along line IV-IV of FIG. 2 through the 11 · imn in this connection disc shown in engagement with a plate shown by a fragment.

In FIG. 1, as an example of application, is shown a plank assembly for advertising use produced by an assembly set according to the invention. The plate shown is comprised of eight flat plates 10, e.g. may be of 2 mm thick cardboard or cardboard and which is provided with advertising text and / or pictures or other information by printing, sticking or otherwise on one or both sides. The plates are arranged in two rows located one above the other with four in each row, and the plate assembly is arranged in a zigzag so that it can stand on its own on a suitable basis. The plates are, where they have opposite edges, interconnected by means of connecting discs 12, which ensure that the planar joint forms a fixed stable unit.

15 An embodiment of a connecting disc 12 is shown in FIG. 2nd

The disc 12 shown here is formed almost like a square with cut corners 1¾. At the center of each side of the disc 12. 16 and perpendicular thereto is formed a 20 edge slot 18 which extends to a distance from the center of the disc 12 and the inner part 19 having a width almost equal to the thickness of the plates 10. However, the slot 18 is not freely open to the edge 16 as it is closed here by means of a nose 20 extending from one side-wall 22 of the slot 18 and thus here integral with the disc 12 itself, which extends face toward the opposite side wall 2k of the slot 18 so that between this and the adjacent edge 26 of the nose there is only a narrow crack. The outward edge 28 of the nose 20 is obliquely cut so that it extends inwardly from the extension of the notch wall 30 2U, thereby forming a notch 30 at the outer end of the slot 18.

As indicated in FIG. 1 and more particularly in FIG. 11, each plate 10 is in such locations where it can be expected to be connected to a connecting disc 12 formed with a longitudinal opening 3, extending perpendicularly to a plate edge 32, the outer end 36 of which is spaced from the edge 32 which is at most equal to the length of the slit portion 19 and which itself has a length corresponding to the length of the nose 20 where it is the longest, i. where it exits from the sidewall 22. The width of the slit 18 corresponds to the width of the opening 3 ^, e.g. with a tolerance corresponding to light running, to the thickness of the disc 12.

The disc 12 may be made of many different materials, but is most advantageously made of such a material which is rigid, yet resiliently resilient, e.g. a resin such as high pressure polyethylene.

If a connecting disc 12 is to be engaged by a plate 10, first the slit end notch 30 is brought into engagement with the plate edge 32, whereby the disc portions on either side of the slot 18 can be removed from one another by a rotation or rotation of the disc. and the washer 12 can be easily pushed over the plate 10- This insertion is made so that the nose 20 will lie opposite the aperture 3, and 15 when it is then released the washer 12 or manually rotates it in the opposite direction of the first twist, among other things, the nose 20, guided by the inclined surface 28, will engage the opening 3k of the plate 10, and due to the resilient resilient nature of the plate 12, the plate will again assume its original shape and in all directions 20 be relatively rigidly connected to the plate 10, from which it does not may inadvertently be taken off. However, if the connecting disc 12 is to be removed from the plate 10, it is only necessary to twist it so that the nose is pulled out of the opening 3, after which the disc can be easily removed from the plate 10.

The connecting disc 12 itself can be formed in many different ways. Thus, in FIG. 3 shows a circular connection disc 12 having, for example, eight edge slots 18, each formed in the same manner as described above in connection with FIG. 2, and these edge slots have an angular spacing of h5 °. However, the disc 12 may also have many other outline shapes, preferably as regular polygons, although in some cases, e.g. oval connecting discs 12 may come into play.

As shown in FIG. Furthermore, in paragraphs 2 and 3, it may often be advantageous for each connecting disc, or at least some of them, to be formed with a center hole 36 9 with which they can be mounted in a differently supported pin or suspended in a string, e.g. when the plate set has to be manufactured a mobile, e.g. may consist of four plates 10 interconnected by two connecting pieces 12 of the one shown in FIG. 2, and through the center holes of the two discs 12, a suspension cord is passed to the mobile, 5 and the cord under the lower connection disc 12 has a knot or other type of stop means which prevents it from being pulled up through the discs. 12th

It should be further noted that in connection with a plate assembly of the one shown in FIG. 1, it may often be appropriate for each plate 10 in the lower row at its lower end to be connected to one or two connecting discs 12, which may thus serve as "legs" for the plate assembly.

It should also be noted that there is in itself nothing in the way that an edge slot 18 can be formed with a plurality of spaced noses 20 and the plate 10 having a corresponding number of series of openings corresponding to the opening 3 ^ -j, which, however, is likely to be capable of bearing only in the case of plates 10 and connecting discs 12 of very large dimensions.

The plates 10, moreover, do not need to be planar, but can be both single and double curved.
