Lanyard

The innovation relates to a connector for the fixed and detachable connection of two translucent ones Cavity panels in the same plane, which are used for exterior glazing of roofs, doors and Windows serve.

The innovation is particularly used when laying such commercially available twin-wall sheets, their length dimensions produced or stored at the dealer for glazing one of these The existing length does not exceed many roof widths sufficient.

It is known to use twin-wall sheets by means of profile strips on their long sides parallel to the hollow chambers

to connect with each other. These lanyards

have a Η-profile, in whose grooves the adjacent

Twin-wall sheets lying on top of one another are inserted |

will. Connecting means for twin-wall sheets, 1 which allow them to be attached to their end faces with one another to connect other to increase their length dimensions, have not yet become known. §

it is the task of the innovation to create a lanyard |

to propose which allows Twin-Wall Sheets jj

To solve the given task ». suggests the new |

Hollow chamber provided socket pin in the form of a;

Section of a rectangular tube, the right ■

Has a longitudinal gap that extends at least over an I.

this socket pin, which is in one of the expected,

The strength of the connection depends on the number of counter- \

overlying hollow chambers of the two S to be connected

Twin-wall sheets are inserted, can be opened on '

simplest and inexpensive way to assemble j

Achieve twin-wall sheets with their end faces. This |

has the advantage that the manufacture of hollow |

chamber plates of extreme length are dispensed with and the bearing I attitude at the delivery company can be limited. Of the

provided longitudinal gap causes the relevant ^; End of the rectangular tube when inserting its circumference
slightly diminishes and gives way, which is the handling when

Connect easier because manufacturing tolerances of the ^

individual hollow chambers are compensated. |

I.

The socket pin expediently has a in its center Recess on. This recess is considered an optical or tactile mark, which makes it easier that the Socket pins are pushed into the two twin-wall sheets to be connected to about half their length.

It is advantageous if the socket pin according to the innovation instead of the recess or also additionally a <r> mior n \\ cq 1i-iq> - I.Hnncri rhHinn standing ΙϊβΠ ^η 1θθΗ

wearing. A tool, for example a screwdriver, can be inserted into this elongated hole during insertion its cutting edge - which prevents the socket pin from being inserted more than halfway into the one ™

Twin-wall sheet is inserted. |

Insertion is made much easier if the front edges on both sides and the longitudinal edges of the Socket pins are broken or slightly rounded.

The socket pin is expediently made of polycarbonate, acrylic glass or polyvinyl chloride, that is to say the same Material like the twin wall sheets.

The proposed connecting means is referred to below on the basis of an exemplary embodiment described in more detail on the accompanying drawing. Show in the drawing

ng. ι Tene of two noniicammer-

plates before connecting with the help of socket pins according to the innovation, with in two

Hollow chambers of the rear hollow chamber plate each have a socket pin with an outwardly pointing longitudinally

is inserted gap.

The shown in Figures 1 to 3 connecting means for twin-wall sheets, for example from 2Q made of clear or translucent polycarbonate is, consists of a socket pin 1 in the form of a ten to twenty centimeters long Section of a rectangular tube 2. This rectangular tube

2 can be made of a suitable plastic or also of polycarbonate.

The dimensions of the rectangular tube 2 are chosen so that it can just be inserted by clamping into the rectangular hollow chambers of the hollow chamber sheets. The QQ cross-section of a hollow chamber is between 6x6 and 15-15 millimeters.

The rectangular tube 2 has on its four side walls

3 each have a narrow longitudinal gap 4 with a width 3g of about 1 millimeter. This longitudinal gap 4

extends over about a quarter of the length of the rectangular tube 2.

In its center, the rectangular tube 2 forming the socket pin 1 has a recess (not shown) or an elongated hole 5 suf, which is transverse to the longitudinal direction of the rectangular tube 2.

tube 2 and its four longitudinal edges 7 are broken or slightly rounded, which is not in the drawing can be represented. These measures make it easier to insert the plug-in pin 1 into the hollow chambers on both sides.

In the figure 4, two sections of twin-wall sheets 8 and 9 are shown, which with their end faces 10 are opposite each other and are in the same plane; here are the open ones Hollow chambers 11 opposite one another. The connection between these two twin-wall sheets 8 and 9 is snapped together a number of socket pins 1 according to the invention, which approximately in every second to fifth hollow chamber 11 of the both twin-wall sheets 8 and 9 are inserted.

The figure shows in the (rear) hollow chamber plate 9 two plug pins 1 inserted into hollow chambers 11, which with their part carrying the longitudinal gap 4 protrude approximately halfway from the end face 10. To connect the (front) hollow sheet 8 is now in the direction of arrow 12 with simultaneous introduction the socket pin 1 in its hollow chambers pushed against the (rear) hollow chamber plate 9 until the the two end faces 10 of the two twin-wall sheets 9 touch each other. Last is to seal the usually

on a carrier resting joint on the top and the bottom of the connected twin wall sheets 8 and 9 a seam made of highly elastic silicone adhesive or a moisture-insensitive, elastic sealing tape glued on.
