Abstract

PURPOSE: To reduce the expenses for manufacturing, assembling and stocking connection parts by enabling connection between the connection part and a mechanism for supporting another cargo while using a connection pin. CONSTITUTION: A connection part 1 includes a tongue 3 as a connecting element integrally formed outside and a through-hole 4. On the other hand, a circular loop as a cargo supporting mechanism includes fork legs 6 corresponding to the size of the tongue 3 and a through-hole 5. Connection between the connection part 1 and the circular loop is easily made by inserting the tongue 3 between the legs 6 and then inserting the pin in both through-holes. In addition to the circular loop, various cargo supporting mechanisms which are provided with legs having the same gap and a through-hole having the same inner diameter are usable. The connection part 1 can be manufactured as an integrally formed forged product, e.g. resulting in a connecting shackle to be eliminated in this case. Expenses for manufacture, assembly and stock are thus reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application J] The present invention relates to a connecting element having a gap that can be closed by a holding pin, and a connecting element that can be inserted into this gap and that the holding pin etc. penetrates through 0I.
In addition, in order to ensure an unmistakable correspondence within the quality classes of components with the same bearing capacity, the dimensions of the connecting elements and retaining pins are such that the parts can only be connected to each other. Luggage hooks of load lifting means, to which hooks can be connected for suspending, shortening or connecting chains, circular loops, bands or belts adjusted to each other and for suspending or securing loads (φ); The present invention relates to a connecting part, in particular an oval annular member, which can be hung on a wall.

[Conventional technology] Connections of this type are known in the prior art.

In this regard, for example, German Patent Application Publication No. 2335131 111 is pointed out. Such a non-confusing correspondence of connecting parts to connecting parts is also known in the prior art. Conventionally, it is common practice to use a shackle to connect such a connecting part, especially an oblong annular member, to another machine groove. These shackles are

12. On the one hand, the parts present the possibility of confusion, since an unconfusing arrangement of the connecting elements attached to each other is only possible if the shackles are precisely matched, and on the other hand, these shackles require additional manufacturing and assembly. Expenses and inventory levels (incurring an increase in inventory).

[Problem to be solved by the invention]

Starting from this prior art, Section 4, which is the basis of the present invention, is to reduce inventory and reduce assembly costs, leading to better confusion-free arrangements with reduced manufacturing costs. The object is to provide a connecting part of the type mentioned.

[Means for solving the problem J In order to solve this problem, the connecting part, especially the annular member,
at least one tab with a through hole integrally formed on the radially outer side, in which a retaining pin is inserted, and a connecting element adapted to the tab dimensions and slidable via the tab; It has been proposed to have flexible legs, with 11 retaining pins attached to these legs.

In this case, it is preferred that, in the connecting part configured as an annular element, the central plane of the annular element extends coaxially with the central plane of the tongue and that the hole in this tongue is oriented parallel to the axis. The connecting part constructed according to the invention can be produced, for example, as a one-piece die forging, in which case connecting shackles etc. can be omitted without any need for replenishment.

This significantly reduces manufacturing and assembly and inventory expenses.

Historically, the integral construction of the connecting part and the connecting part ensures that on the eccentric side only parts that are attached to each other can be connected to each other. That is, it is no longer up to the user to additionally connect parts to each other by means of the shackle arrangement n, which should not be connected to each other for safety reasons.

In a further configuration, two tongues are arranged on the short sides of the oblong annular element spaced apart from each other and in particular oriented symmetrically with respect to the longitudinal axis of the annular element (as proposed). (Figure 2).

Another preferred configuration is furthermore as a circular loop connecting element:
A connecting curved piece is provided with only two forked supports adapted to suit the load, as can be seen in the curved area of this connecting curved piece surrounded by the circular loop (FIG. 4). ).

Historically, it has been advantageous to provide an approximately triangular connecting curved piece with forks adapted to suit the load as the strip connecting element (FIGS. 5, 6, 9a, 9a, 9b). Figure 9b).

It is particularly preferred that all connecting elements have a fork, which with respect to the spacing of the gap, the arrangement of the holes, the size of the holes, the connecting pin, the thickness of the material and the depth of the fork insertion gap. It is designed in such a way that it can be connected only with the tongue of the other part, which tongue is designed in such a way that it allows a good correspondence with respect to the above-mentioned parameters.

As a variant, a shortening claw for a circular link chain can be held on the tongue of the annular element by means of a connecting pin.

As a further variant, the connecting element can be a luggage hook with a connecting fork.

In a further development, a further connecting part is arranged on the band- or chain-like supporting part, which is adapted to the supporting part, and which has a connecting fork. An integrally formed tongue piece of another connection part is an insertion HJ function,
It has been proposed that as a further connecting part a part with N number of chain-connected forks for forming a multi-rope U, a tether, is arranged.

For this purpose, it is advantageous if the further connecting part has a protruding tongue on one side and a fork for supporting the chain element and a hole for inserting the connecting pin on the side edge. be.

EMBODIMENT OF THE INVENTION An embodiment of the invention is shown in the drawings and will be explained in detail below.

According to the invention, there is provided a connecting part, in particular an oblong annular member according to FIGS. The mechanisms shown in each figure of the drawings are connectable and are used to shorten or connect chains, circular loops, bands or belts.

These load lifting means allow the load to be hung or secured. Each connecting part l has at least one connecting element 3 with a hole 4 through which a connecting pin can pass. The connecting part corresponding to this connecting element has a gap 2 into which the connecting element 3 can be inserted,
This connecting element has a hole 5 for inserting a retaining pin.

According to the invention, the connecting part l is provided with a tongue piece as a connecting element 3 integrally formed on the radially outer side and a through hole 4 through which a retaining pin can pass. The attached connecting element 6 has legs adapted to the tongue dimensions and movable via the tongue 3, on which retaining pins 11 are attached.
It is possible to pass. In the connecting part l, which is designed as an annular element, the central plane of the annular element extends coaxially with the central plane of the tongue 3, the hole of which is oriented parallel to the axis. This is particularly clear from FIGS. 1 and 3. In the variant according to FIG. 2, two tongues 3 are arranged on the short sides of the oblong connecting part l, these tongues being spaced apart from each other and in particular symmetrical with respect to the longitudinal axis of the connecting part. placed towards the target.
