DE817644C - Reinforcement strip for wooden panels, especially for toilet seats - Google Patents

Description

It is known to provide wooden panels with reinforcing strips and to use round bars for this purpose. This has also been suggested Subdivide reinforcement strips and use special parts with the wooden plate to conclude flush. It resulted. that when pressing the round bars into the provided grooves in the wooden panels, the friction was often too great and the round bar broke off or was pulled. The friction also continued the use of round bars with a larger diameter a very narrow limit.

This is where the invention comes in, which includes both the production of wooden panels Simplified with reinforcement strips as well as the strength of the product and its durability significantly increased. According to the invention, this is achieved by the arrangement reached by grooves in the surface of the round rod, which once when pressed in significantly reduce friction in the grooves in the plates, but also when they become wet the plates in their use, e.g. B. in toilet seats, by swelling under Grooves created by strong pressure increase the durability significantly. Also is Now the use of larger cross-sections of the rod is possible because the press-fit is no longer so tightly limited by the risk of breakage as it used to be.

In an exemplary embodiment, the invention is shown in FIGS Drawings shown.

Fig. I shows a diagrammatic representation of three plate parts, which connected by two bars with grooves; Fig. 2 shows a side view of a Plate part, with the previously usual cross-section of the reinforcing rod for comparison indicated by the faint circle; Fig. 3 shows the side view of a plate part with the rod with grooves according to the invention; Fig. 4 shows the reinforcement rod in perspective view with grooves lying parallel to its central axis; Fig. Figure 5 shows an embodiment with grooves in a spiral arrangement around the rod placed or pressed into it; Fig. 6 shows the application to a toilet seat; Fig. 7 shows a cross section according to Fig. 6 at the location of the reinforcement insert and Fig. 8 is a cross-section along line X-X in Fig. 6.

The drawings clearly show how the surface of the in the grooves according to Fig. 2 to be pressed in reinforcing rod of any shape, in particular Round bar, is reduced by the provided indentations (grooves), whereby The grooves also have the neighboring material when they are pressed into the grooves Can give rough to evade. «'The X-grooves are still grounded by pressing produced, these parts swell up again later and thus increase again Their connection with the wooden parts increases the strength and durability of the whole Plate.

Since the frictional pressure during press fitting is significantly reduced, can now also stalls with a larger surface, i. il. thus finitely larger diameter can be applied, whereby another advantage is achieved.

The cross-sectional shape of the reinforcement bar and the type and distribution the grooves are not critical to the use of the invention as the inventive concept essentially ordered by reducing the surface in forin of depressions on the surface of the rod or on the adjacent surfaces of the Nest or on both surfaces to reduce the drawing for (las l: inl) resseti and thereby achieve the erN \ -ilititcti advantages.

Of course, you can also use the well-known divided Forin of the stick as shown in Fig. 6.
