DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention is directed to a linear coupling for transmission of large tractive and alternating forces, as they occur in the course of transportation and assembly of finished concrete parts, in vehicle couplings, during container loading etc.
The presently known couplings for finished concrete parts, as described in CH PS No. 535 180, 562,382 and 620,261 all have the disadvantage that for the coupling operation and locking or unlocking and decoupling, rotational and horizontal movements are required.
Vehicle couplings (trolleys) are known which do not exhibit the above disadvantages and even permit an automatic coupling operation, but are far from being free from play, but for that are large and heavy.
SUMMARY OF THE INVENTION
It is the object of the invention to create a coupling member, which is up to transmitting large tractive- and alternating forces over a long period, free of play with small dimensions in rough operation (construction site, railroad, port), enables an automatic operation, hereby provides a maximum of security and can be rationally manufactured, assembled and replaced. Also in the case of shaft offset with non-aligned parts a coupling engagement should be possible.
The inventive coupling which satisfies these requirements comprises of a pair of coupling members each being formed as a fir tree-shaped cone. The coupling members are secured together in combination with corresponding connection members comprising of a plurality of segments and a locking member comprising of a sliding coupling sleeve.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
In FIG. 1-4, each of the coupling links 11, 12 is connected to a different rod end portion A, B and consist of a fir tree-like, externally wavy cone 11, which is solidly connected with the product to be conveyed, or part B. An identical cone 12 is connected with the crane cable, or part A. The waveform surface 19 is made up of alternating lands 19' and grooves 19".
The connecting member 13 consists of six circular segments 13, which can embrace the waveform 19 of fir tree cone 11, 12 with their inside waveform 18 including lands 18' and grooves 18" in a psotively locking manner for coupling end portions A and B together. The sliding box or coupling sleeve 14 on the one hand retains the segments 13 together and causes on the other hand during the locking operation the open sides of the segments 13 to pivot inwardly, whereby the lase waveform 19 or land 19' of the cone 12 serves as a series of fulcrums 15. The outwardly facing surfaces 20 of the segments 13 form a cylindrical outer surface, note FIGS. 2 and 4. Intermediate the ends of the surfaces 20 there is an annular groove 21'. The interior of the coupling sleeve 14 has an annular groove 21". When the coupling sleeve is slid into the locked position, the groove 21" is in register with the groove 21' in the segments 13. In FIG. 1, the annular grooves 21', 21" are spaced apart in the a
