^ "Fastening device on a sign (company logo, ^: . Lettering, emblem) for attachment to bodies, apparatus housings and similar flat bodies." / *

The invention relates to a fastening device on a sign (company logo, lettering, emblem) for attachment to bodies, apparatus housings and the like. Flat bodies through the back of the shield body attached pin-like projections, which in their strength according to the Rise the shield body conically, pass through a hole in the shield carrier made of sheet metal land are tapered in diameter at a distance corresponding to the sheet metal thickness of the shield carrier.

There used to be such signs made of aluminum with deji attached fastening bolts in the cold impact process manufactured. Today they are also made from plastic, because this is now used its surface can be refined to such an extent that it has an absolutely metallic appearance and behavior is offered.

The attachment of such signs is carried out in various ways, and in the end almost exclusively through rubber grommets and "speed nuts" namely, these are pushed onto the pins from the inside of the body. Under "Speed-Nuts" are perforated metal rings with radial cut into their interior Struts run in the manner of barbs in the circumference of the fastening pins dig in, Since the aforementioned material change from aluminum to plastic, the previous Mounting method not changed yet. As the attachment of these fasteners mentioned must be carried out in the interior of the body, the assembly is dependent on skill, i.e. complicated »Often the assembler falls out of his hand the fixing part from which in the remaining at least 3 pieces are needed for the attachment. Overall, above all is the Wage share still too expensive.

The invention is based on the task of simplifying assembly and thus the wage share to belittle.

Invention Γ, '";' - iriM. '' This problem is solved

a) that each of the pins in plan view a long, substantially rectangular horizontal Has cross-section and on the long outer sloping surfaces forming a sharp Paragraph edge is constricted so that the pin heads with relatively long contact surfaces sit on the corresponding perforated edges of the label holder plate,

b) that each of the pins by one extending in the vertical plane of symmetry is sufficient wide separating cut is divided into two springy pin halves and

c) that the cuts parallel to the long side of the shield in the same or else - at staggered arrangement - run in parallel planes =

The ötiftkÜrper itself can be used in the manufacture of plastic shields in one piece and made of the same material, whereby the Production is significantly cheaper.

The pen body can also be used as individual parts made of metal and provided with flange-like foot areas with which they are in the back surface of the shield is molded (injected or cast in).

In this case it is also advantageous if the scope of the pen soot is known per se V / ise thickened towards the foot end in order to strengthen the integration into the shield body, or at least on two opposite end faces projections or recesses to the same Purpose are provided.

Finally, for reasons of durable and good suspension, it is an advantage if the two have the Separating cut bounding surfaces run successively rounded at its deepest point.

It is also an advantage if the outside world

Rare straightened edges of the over the support surface located head piece halves to facilitate the introduction into the fastening opening run rounded.

After all, it's in the making of
Signs made of plastic with directly formed fastening pins of advantage if on the back of the Ächildkörpers around the
A recessed ring area is formed around each pen body. In this way, a small sheet metal tolerance or a small punching burr can be compensated and the injection molding tool; i
produce and operate cheaper, which has to form these pins.

In the drawing, the subject matter of the invention is shown in an exemplary embodiment.

Fig. 3 to ty fiinaelheiten greatly enlarged, namely in two different 90 ° directions and Fig. 5 is a plan view of the body panel.

The shield body 1 made of plastic has on its rear side (FIG. 2) a slightly raised edge 1 ^a all around, which serves to keep the attached shield under tension. In addition, the üchild 1 here has three mounting pins lying in a line, with dash-dotted circles x, y, z only to indicate that these pins can also be offset in a different arrangement. It is important that the direction of the column of the pins to be discussed should run parallel to one another, as is also shown in FIG. 2 in dash-dotted lines.

The Karrosserieblech 2 has at the fastening points for receiving the fastening pins rectangular ft-vrchbrechungen 2 ^a, whose long edges 2 have a longer dimension b, as the shorter edges 2 °, the distance is indicated by%.

Length over the edge of the hole 2 of the hole 2 of the Karrosaeriebleches ^ reaches away. By comparison with FIG. 4, it can be seen that the two pins have a considerable width and also run diverging on their side edges in order to overlap an edge 2 which is as long as possible. The two side edges 1 are also rounded. In this way it is easy to Jcann in the hole ^2a of the sheet 2 to introduce the pin body with its front end and mount by a slight impact with the hand without creating even counter-hold on the sheet metal body.

In FIG. 2 also shows that in the preparation of the shield body made of plastic of the same shape can be injected from the metal pin body having a unterSj) ^ Jf (L / -fiOen l ⁽¹ USS in this case r have. Instead, or in Community

This means that the surfaces that come into contact with plastic can have protrusions and recesses own to improve grip.

Fig. 3 shows that the facing, the gap 1 delimiting surfaces run one after the other at the bottom in the foot area 1 so that the cross-section increases at this point.

From Fig. 2 it can also be seen that around the pin pairs 1 ^C , 1 ^C sunk cavity 1 is formed, which compensates for tolerances of the sheet metal thickness or small punching burrs of the sheet metal body with a corresponding size of its diameter. But it also proves useful for the Y / tool parts of the injection mold to form the undercuts.
