Lampshade and kit for do-it-yourself construction.

Lampshades, especially those that can be made by skilled hands *, come in different designs known, there are in particular two basic types, one of which has a support frame usually made of wire, which with Spanned fabric, paper, cardboard or plastic. The covering material can also consist of individual sheet-shaped flexible ones There are parts that are firmly connected to each other and to the support frame. Except that kind of old lampshade lampshades have become known recently, weldie consist only of releasably interconnected sheet-shaped flexible parts made of paper, cardboard or plastic. Be there

in particular for the latter training the items are often supplied as kits that come in a small flat Package ö.j individual leaf-shaped parts as well as that to their Compound provided material included.

The present innovation is based on a lampshade of the latter Type, i.e. a lampshade, consisting of releasably connected sheet-shaped flexible plastic parts, Such a lampshade produced by the user from an existing kit in the simplest way become and after assembly high strength and long

Attention to the connection between the individual plastic parts, which should be very easy to manufacture and at Achieving a firm connection allows for a wide range of variations in the individual plastic parts and, as a result, the ones to be produced Lampshade forai should result.

A lampshade according to the invention of the aforementioned type is characterized essentially by the fact that the plastic parts · ■ border strips corresponding to one another at their connecting edges with matching holes and to connect de? Plastic parts can be pressed into these holes with one another button-shaped connecting pins with mushroom-shaped or plate-shaped widened head are provided.

In this case, the edge strips of at least some plastic parts are preferably divided off by pressed-in grooves and longitudinally these grooves are bent over in such a way that the edge strips of abutting plastic parts can be pressed smoothly against one another. Since the holes in the edge strips that are pressed against one another are exactly on top of one another, the connecting pins can be

impress easily and thereby clamp both edge strips firmly together. To dismantle such a lampshade, if If it is to be cleaned or possibly given a different shape, the connecting pins only need to be removed from the holes in the Edge strips to be pushed out again, whereby the individual plastic parts fall apart again. Next to her The bent edge strips can also have a decorative effect and the external appearance of a structural function make such a lampshade more lively.

In a preferred embodiment of the innovation, they point to one another squeezable edge strip to the outside and is in them at least one parallel to the pressed-in groove Incision provided so that part of the edge strip can be bent out of the plane of the edge strip as a lip, while these lips near their end a hole for inserting a connecting pin for two or more of these lips one or have several plastic parts. As a result, these lips stiffen the plastic parts and also achieve a extraordinary decorative effect.

Below are two preferred embodiments of a lampshade according to the innovation with reference to the accompanying drawings explained in detail, with further particularities of the innovation coming to light; show it:

FIG. 1 shows a single sheet-shaped plastic part before its deformation in a plan view;

FIG. 2 shows a perspective representation of the plastic part from FIG. 1 after its deformation with a representation

Andrejewski, Honke & Gesthuysen, patent attorneys, 4300 Essen, Theaterplatz

the connection of the same with a second similar plastic part;

FIG. 3 shows a section through a connection point of the edge strips two plastic parts according to Pig. I;

Figure 4 schematically shows a twenty parts according to Fig. 1 J assembled lampshade, although from

The lips have been omitted for clarity of the figure;

Figure 5 shows a second embodiment of an innovation according to the invention Lampshade in side view; and

FIG. 6 shows a plan view of the lampshade according to FIG. 5.

The lampshade according to FIG. 4 consists of twenty plastic parts according to FIG. 1 of the same type in shape and dimensions. Each

_ As FIG. 1 shows, these plastic parts consist of a Jt
^w circular punched flexible plastic sheet of suitable composition, such as polyvinyl chloride, xn which three grooves 1 are pressed, which form an equilateral triangle, the corners of which lie in the outer edge of the plastic sheet. These grooves 1 thus separate the plastic part into a triangular main plane 2 and three circular segments. · Shaped edge strips 3. Each of these edge strips has a »from one side parallel to the press groove 1 and to the center of the edge strip notch 4, which thereby separates a lip 5 from this edge strip. Also are

Andrejewski, Honke & Gesthuysen, patent attorneys, 4300 Essen, Theaterplatz 3

three holes 6 punched out of each edge strip 3 along the pressing groove 1, while a single hole 7 is punched out of each lip 5 near its free end.

To produce a lampshade from these plastic parts shown in Figure 1, these are first in the Figure 2 shown deformed way. To do this, the edge strips 3 along the pressing grooves 1 to the same side and then the lips 5 bent inwards so that their ends lie against each other in the middle above the main level 2. The lips are then moved so far that their holes 7 are exactly one above the other, whereupon a connecting pin 8 of the design shown in Figure J5 is pushed through these holes will.

The plastic parts deformed in this way are now placed with their bent-over edge strips 3 against one another, as this is shown in Figure 2 for two plastic parts. By the now coinciding holes 6 in the edge strips are in turn pressed connecting pins 8, so that a firm, however, releasable connection is achieved at any time. The connecting pins 8 exist, as shown in FIG is, from a short in the holes 6 respectively. 7 can just be pushed in Shank and a mushroom-shaped or plate-shaped widened head 9. These connecting pins are also expediently made of plastic, if naturally, if so Should it be desirable for decorative reasons, any other material such as wood or metal can also be used.

Andrejewski, Honke & Gesthuysen, patent attorneys, 4300 Essen, Theaterplatz 3

In the manner described above, twenty triangular plastic parts deformed according to FIG. 2 can be formed Produce a lampshade in the form of a polyhedron, as shown very schematically in Figure 4 with the omission of the lips is. The plastic parts have a hole 10 in the middle; through which the electrical cord of a Pendulum can be pushed so that the last piece of fabric I "of the polyhedron is pushed onto the line 11 and then a lamp socket can be attached (Fig.4), whereupon this last plastic part inserted into the remaining triangular opening of the polyhedron and with its edge strips is attached to the corresponding edge strips of the adjacent plastic parts.

The material of the plastic parts is naturally translucent and can be white or colored. The connecting pins 8 can be the same color as the plastic parts own or be colored differently for decorative reasons.

The lampshade shown in Figures 5 and 6 consists * from six elongated rectangular parts IjJ, which become one rigid elongated quiver with hexagonal profile are interconnected. Here have the parts 13 on their long side edge strips 14 respectively. 15, one edge strip 15 being wider and additionally one through a press groove has limited narrow approach l6. This approach 16 can be designed as a continuous additional edge strip be or several lobe-like short lugs 16 can be provided.

As Figure β shows, the parts 13 with their inward bent edge strips 14 and 15 placed against one another and then connected to one another by means of connecting pin 8, which in the coinciding holes 6 are pressed. To improve the rigidity, the narrow edge parts or approaches

16 of the edge strips 13 are bent over the outer edges of the adjacent shorter edge strips 14.

The lampshade shown also has also a number of strip-shaped parts 17, the indicating in a plurality of rows one above the other on the outer side of the quiver made of the parts IJJ? ^'I are eight. For this purpose, the parts 17 ise We-bent to the illustrated and with their ends at the location of the connecting pin 38 pushed between two adjacent edge strips 14 and 15 of the parts 13 and then clamped with the aid of the pressed-in connecting pin 8. These parts

17 can also have a hole at their ends for pushing through a connecting pin 8 for this purpose, they can but also have recesses in a longitudinal edge near their end and then simply from above over the connecting

™ pins 8 can be pushed.

The edge strips 14 and 15 of the parts 13 can be in the respectively desired height have incisions in which a wire ring

18 can be inserted, to which the lamp socket is then attached in a manner known per se.

To the decorative effect of the last described embodiment To increase a lampshade according to the innovation, its parts 13 and 17 are preferably designed in different colors.
