Pipe track hook

The innovation relates to pipe track hooks, especially for meat, with a slide hook that extends over a pipe track and a load hook rotatably mounted on this.

So far such Rohrbahnglexthaken that in all meat ^ Manufacturing plants used have been made of steel, with protection against corrosion either through the use stainless steels or through corrosion-resistant surface coating was achieved. Such Rohrbahnglexthaken are expensive and heavy.

There are also already known pipe track hooks in which the load hook with the sliding hook is made in one piece from corrosion-resistant, heavy-duty plastic is made.

The object of the invention is to provide Rohrbahnglexthaken, in which to facilitate the processing of the hung pieces of meat the load hook is rotatable with respect to the sliding hook suspended on the pipe track, to be designed in such a way that the parts made of plastic

fabric can be easily manufactured and a sufficiently resilient, reliable connection of the two elements is created.

This object is achieved in that in the Rohrbahngleithakan made of plastic on the load hook molded pin with fastening head is pushed into a bearing eye of the sliding hook that is open on one side. Load hook and sliding hooks can be manufactured economically by injection molding and assembled into a ready-to-use tubular track sliding hook without any further treatment.

It is advantageous to have both hook parts made of glass fiber reinforced To produce polyamide, a load capacity of up to about 300 kg is achieved without difficulty.

In a further embodiment of the invention it is provided that the contact surfaces of the fastening head of the load hook and of the bearing eye of the sliding hook are provided with a sliding pad made of wear-resistant material. This will make it smooth Rotatability secured. According to the invention, the sliding pads be metallic disks anchored in the plastic, which are inserted into the injection mold and their anchoring projections be overmolded during hook production.

The innovation also provides that when the fastening head is inserted, the insertion opening in the bearing eye to secure the loading

fastening head is closed by a plug. Of the The stopper can be glued or welded in or snapped into projections on the bearing eye. The stopper can also be designed in this way be that it engages around the slide-in side of the bearing eye is.

It can be advantageous to provide the sliding hook on the surface coming into contact with the pipe track with a sliding support made of abrasion-resistant Material to be provided.

Further details of the innovation can be found in the following description in which, with reference to the drawing, exemplary embodiments of the Rohrbahngleithakens according to the invention are erlauf ert.

In the drawing shows

1 and 2 show a tubular track slide hook according to the invention in Front and side view,

Fig. 3 is a section along the line III-III through the bearing eye, 4 shows an enlarged partial view of the swivel joint, FIG Stopper in a different design.

In Fig. 1 and 2, the slide hook 1 made of plastic can be suspended over the tubular track. The sliding hook points at the lower end a bracket-like protruding bearing eye 2, with stiffeners 3 on two sides and with an insertion opening 4

on the side opposite the hook shaft. An integrally formed at the upper end of the load hook 5 also made of plastic The pin 6 with a fastening head 7 is inserted through the insertion opening 4 into the bearing eye 2. The bottom of the fastening head rests on the top of the bearing eye. To improve the sliding properties when twisting against each other of the two parts of the tubular track sliding hook can these touching surfaces, as shown in FIG. 4, with metallic sliding washers 8 and 9 may be provided, which have anchoring projections 1o and 11, which are also encapsulated in the manufacture of the hook parts, are attached.

In Fig. 3 is a bearing eye 2 with a slightly conical insertion opening 4, which can be closed by a correspondingly shaped plug 12 after the load hook has been inserted. Of the Plug 12 can be glued in, with projections 13 the attachment to back up.

In Fig. 5 are on the open string of the bearing eye 2 directly 4 fastening lugs on the edge of the insertion opening. 14 arranged, which snap into the plug 12.
