Title.

Spring section as a connection workpiece »between individual material sections.

Description.

The illustrations are used to identify the type of connection on - sheet 5 - decisive.

The spring section is always about a third as strong “Le the strength of the individual material list to be connected üeke.

In the drawing, the connection is 24 m / m thick Floor boards (1) + (2) with hats (3) ♦ O) shown ·

In this case, the Fedex section (5) is 8 m / m thick and 17 m / m wide. Bs has slits on the front sides (6) + (7) tone provided for each 6 m / m depth. The wedges (8) + (9) are inserted into these slots. The left figure, the drawing - sheet 5 - shows the connection of the joined material parts

Heinrich Hüneke: - Sheet 2 - The new material! The pre-production

Both of the connected workshops take part? tücl'e (1) * (2) inherited an incorporated *) dovetail-shaped hat (3) + (Ό · The material spring part (5) is in the required Newly made size and provided with a shiit * (6) + (?) On both sides in the middle »

The material wedge pieces (8) - «(9) are used in the required Strengths made in bar form.

Assembly.

in the two 5c hl it ze Co) -K?) the material fsdsrstsil = Piece (5) the wedges (8) + (9) are used. The three pieces of material (1) - »- (5) + (2) are put together, whereby the wedges (8) + (9) sit on the groove rear walls of the material parts (i) + (2). With further knocking together of the pieces of material the wedges push the four spring halves apart and thus against the upper and lower groove walls, so that the dovetail grooves are completely filled.

With this, the connection of the two material parts is fixed and non-detachable by the new material spring part become one piece; because the material spring section is due to the mutual wedging in the grooves the material parts (i) + (2) can no longer loosen and thereby the later creation of an eye is excluded will.

Heinrich Hüneke - Sheet 3 -

The gate parts that result from this new type of connection are in addition to the economic savings better execution at a- production of flat marks of ff laugh.

These new material surfaces are without nail holes and a later joint formation is impossible. There is also better utilization in the width of the boards possible because the spring loss in the entire material surface not applicable.

The manufacture and use of the new material spring section as described in the description should be protected and drawing is shown.

Claims (3)

Heinrich Hüneke. Sheet - 9 - 4I Claims for protection. 1. Spring element (5) between all connecting workpieces Material parts (1) + (2). The cross-sectional area of the spring section has a rectangular shape. The size of the rectangle is different according to the material parts to be connected. The width of the rectangular area is approx a third as wide as the outer material part + niches are strong. The height of the rectangles is about 4 m / m shorter than the Meaning of the two depths of the hats (3) + (4-) to the see below connected material parts · The broad sides of the spring partsβ are in the middle with sawed-in slots (6) + (7). The V-strips (8) + (9) are inserted in the slots. The spring section is made of wood 2. spring section as claim under 1., characterized in that that it is made of light metal. 3. spring section as claim under 1., characterized in that that it is made of plastic. M-. Spring section as in claim under 1., characterized in that it is made of molded laminate.
