Device for joining panels or foils

The hiring relates to a device for connecting at least two plate-shaped or film-shaped parts made of consists of a shaft provided with an impact head =

For example, such a connection is required for plastic panels that are used as a sheathing for the insulation of Heating pipes are used, but the application is not limited to this and the connection can also be used for other materials, how cardboard, plywood and the like are attached / ended =

Attempts have already been made to connect such plates or foils by gluing or by applying a self-adhesive layer carry out, but had to find out that no permanent connection is guaranteed, since the adhesive layers with tire with time and since most connections are under tension, even if they are low, they tend to expand after one more or less long periods of time.

They went out to the above-described devices ü "ber ₉ which are practically defined by the positive part of a push button" To carry out the connection using such a device must first naoh the Zusamme.nlegen the parts to be connected are drilled holes or beaten, it These holes have to be kept flush in the two superimposed parts to be connected and then the snap fastener part is knocked in. Apart from this tedious work, it is also relatively difficult because holding the parts to be connected together after drilling the holes in one layer , in which the bores must exactly coincide, requires great dexterity in practice at unclear installation sites =

There is also the fact that when loosening the connection, which is also required from time to time, the holes when pulling out tear open the device so that they are not usable again ξ the thickening namely settle in the known Devices consistently seamlessly on the shaft of the device aa. ·

One of the tasks of the present furnace is to provide one of the initially to improve the devices described in such a way that the assembly τ / it is shortened and simplified and that when loosening the connection by pulling out the device no damage to the plate holes can occur.

According to the regulation it is provided that the free end of the shaft in the direction of the door or »that the thickening is tapered to a point» Two work steps are required during assembly saves j namely that of drilling and that of holding together of the panels with aligned holes after drilling. The new device is simply in the intended place with a Hit hit and the connection is ready = special skill is no longer required »

Since in further training, the furnace, the transition from the shaft to the thickening is conical or rounded _? if the connection is loosened by pulling out the device on the plate, the holes will not be damaged »

Bs has also been found to be useful, the length the tip including the thickening at least about the same the diameter of the thickening or at most about three times the diameter of the thickening. .

The new Toe device consists of the shaft 1 with the impact head 2 and the thickening 3 _S which tapers into a point 4 towards the free end. In the example described], it is provided that the length 5 of the tip 4 including the thickening 3 is at least approximately equal to the diameter of the thickening 3 or at most about three times the diameter 6 of the thickening »

In the example of Figure "2 it can be seen that the two plastic plates are held together by the erfindungsgemäJe device 7 and 8 ₀ is connected to a shock caused by the two plates driven through without previously holes were present as / them through the tip 4 are formed by themselves. Compartment driving through the Verdiokung 3 holds this together with the impact head 2, the two plates 7 and 8 close to one another o

n as it is provided according to the innovation to produce the device from a material that can be influenced by a magnet, can it be made with an impact tool 9? which contains a magnetic insert 10, held and hammered ο , "':'. '.
