^fl Heat protection spacer for fittings on cooking and roasting equipment "

Ss are fittings made of plastics, preferably thermosetting plastics, known, which because of their inadequate thermal resistance not directly, but via a metallic spacer be connected to the vessel wall. The use of such spacers, however, has the disadvantage of high costs on the one hand with itself, since they are generally made of cast light metal for manufacturing reasons or other highly thermally conductive materials exist, which on the other hand, in turn, the risk of charring that conjures up connection zones.

The present firing combines the advantages of a spacer, without having to accept its previous disadvantages. According to the innovation, the spacer consists of an open sheet metal part that is easy to manufacture and has poor thermal conductivity. Here, too, the fastening is carried out by means of. Screw connection. The end face of the plastic fitting is preferably supported with the side opposite to the direction of heat attack on the device wall completely or partially, while the remaining forces can be transmitted via the spacer. It is also possible, the plastic part does not go up to the device wall and to leave its support entirely to the spacer. For reasons the lowest possible heat transfer spacer and fitting are designed so that between the two only for the Force transmission required contact is created.

The secure power transmission was made possible by the fact that the flank ends of the spacer are securely supported against the plastic fitting and by the fact that the open ends of the sleeve-shaped spacer are securely accommodated in the plastic. A deviation of the plastic fitting part relative to the spacer or the device is avoided and thus sufficient strength for practical use is achieved. -._---

The modern design of the spacer and the fitting ma.chtv.es possible, a cheap construction of sufficient security from thin-walled material of any shape! to "create that by / use poorly thermally conductive Materials, preferably of stainless steel, are highly suitable for use on all stoves. Expensive sweat or other connection processes with corresponding laughing work are not required.

In. the drawings show the firing in several examples, which can be modified as desired. Show:

Figure 1 is a longitudinal section through a plastic pan handle,

Figure 2 shows a cross-section A-B, according to Figure 1,

Figure 3 is a longitudinal section through a plastic Pfan -.- nenstiel,

FIG. 4 shows a cross section A - B. according to FIG. 3,

Figure 5 is a ^ longitudinal section through a plastic pan handle, '■

FIG. 9 shows a longitudinal section through a plastic material ohinehtopf handle,

Figure 10 is a longitudinal section through the leg of a Plastic side handle,

FIG. 11 the top view of a plastic side handle according to Figure 10.

Figure 1 shows a pan 1 with the fastening bridge 2, in which - the screw 3 is hung with its head. The mother 4 clamped over the spacer β the plastic handle 3 with of the pan 1. The handle 3 rests only with the top edge of the front face on the pan wall. Figure 2 leaves the intimate Connection of the spacer 6 designed as an open sleeve. recognize with the handle 5. The sleeve ends angled downwards are securely accommodated in slots in the plastic.

The execution of the pan handle according to Figure 3 corresponds in the essential, semlichen tier previously shown, with the difference that the fastening bridge 2 receives a nut this time, while the screw head is housed at the end of the handle. In the flank zone of the spacer, the stem 5 has no contact _{Vs (5} because this was limited to the connection or part of the stem stem in the surface ⁵ '"). FIG is seen 'that the open ends of the spacer 6 in addition to the increase of the safety in ^horizonta-: ler were angled direction.

FIG. 5 shows a type of fastening that differs from a shorter one to those previously described, i. h, does not provide a screw connection running through the full length of the stem. In

In this case, the open grommet ends of the grommet 6 with their Bends set directly in front of one another. That way is. it is possible not to lead the handle 5 through to the socket wall 1, without · creating any dirt corners with anyway adequate security.

FIG. 6 shows the situation in cross section, whereby it can be seen is that the contact between the stem 5 and the spacer -6 limited to just a few places.

Figure 7 shows that the stem end face of the Handle 5 fully carried out to the wall of the pan, without too intimate a contract between the plastic handle 5 and the pan 1 is achieved. This is achieved in that the stem end face has recesses. Figure 8 shows that the open grommet ends of the grommet 6 also only up to the side wall. the plastic part can be raised and that there is still sufficient security.

FIG. 9 shows the corresponding application in a machine pot handle, a screw connection also being provided here. In this case, too, the fitting part 5 can be carried out completely or partially or not at all as far as the harness wall 1.

Figure 10 indicates the analogous application of the proposed ! Price increases for side handle covers. Figure 11 shows this arrangement in top view. If the distance from the heat source is appropriate, it is also possible to move the open grommet ends afterwards to be laid at the bottom, especially since then - as shown in FIGS. 10 and 11 - when the bends of the spacer 6 are immediately in front of one another and thus represent reliable thermal protection.
