Definitions
- the invention relates to a device for the releasable connection of two parts according to the preamble of patent claim 1.
- Tow trucks For example, an insufficiently braked, towed vehicle can drive onto the device and thus initiate an unlocking, which then leads to a loosening of the tow rope when the tow vehicle pulls again.
- the object of the invention is to remedy this problem.
- the object is achieved by the features stated in the characterizing part of claim 1.
- the measure, which is relatively simple in accordance with the invention, now for the first time achieves that the connection can only be released in an absolutely arbitrary manner.
- the design according to claim 2 results in symmetrical pressure conditions on the unlocking part.
- the design according to claim 3 ensures that unlocking only by arbitrary, e.g. manual grasping and pushing back of the handle is possible.
- the training according to claim 4 offers a clean solution for the protected accommodation of the spring, while the training according to claim 5 completes the protection for the spring and the handle part together with the
- the training according to claim 6 in connection with the training according to claim 5 serves the elegant release by the possibility of sliding into each other of the receiving part and the handle.
- the training according to claim 7 has proven to be particularly stable. With such a design, stronger pulls on the locking bolt in the direction of the opening result in a stronger locking of the device and thus prevent unwanted loosening when there is a pull.
- the training according to claim 8 is easy to manufacture and, above all, easy to assemble.
- the training according to claim 9 facilitates the attachment of a rope to the locking bolt. In contrast to what is known, in the invention a play of the locking bolt within the receiving part is limited to the extent of its displacement contour.
- Fig. 1 shown in the drawing shows a section through a device in the locked state as an example of a possible embodiment.
- a receiving part 1 can be fastened with its base 18 to any objects (e.g. a vehicle chassis).
- a hole 19 is provided opposite the bottom 18 and serves for the penetration of the locking bolt 9.
- the receiving part 1 is undercut in its interior and thus offers space for a bolt 5. This is formed from four cone-segment-like segments 14, which are held together by an O-ring 15 in a groove 20.
- a mushroom-shaped displacement part 12 is attached, which has a displacement contour 13 with which it displaces the segments 14 against the force of the O-ring 15 when penetrating into the receiving part 1. If the displacer part 12 has penetrated completely through the bolt 5, it cannot be withdrawn on its own, since the bolt 5 springs back to the original inside dimension of the locking bolt 9.
- An unlocking part 11 slides freely on the locking bolt 9 and is integrally connected to a handle 2 via a connecting wall 3. Between the handle 2, the connecting wall 3 and the unlocking part 11, a space 4 is formed which receives a spring 10.
- the spring 10 is supported at one end on the connecting wall and at another end on a counter bearing 6 is movable between the handle 2 and the unlocking part 11 in the axial direction of the locking bolt 9.
- the counter bearing 6 is held captive in space 4.
- the inner diameter of the handle 2 is slightly larger than the outer diameter of the receiving part 1, so that the handle 2 can slide over the receiving part 1.
- the wall of the receiving part 1 enters the space 4 and acts on the counter bearing 6, which compresses the spring 10.
- the unlocking part 11 which has a smaller outer diameter than the bore 19 of the receiving part 1, penetrates through it and acts on the inside of the segments 14 with a displacer contour 17. If the unlocking part 11 has a sufficient depth of penetration, the unlocking part 11 closes flush with the displacer part 12. Only at this point in time can the locking bolt 9 be withdrawn, since the segments 14 no longer represent a lock for the displacement part 12.
- the locking bolt 9 has at its end facing away from the displacer 12 a thread 16 which, with a clamping piece, not shown, serves to receive a rope end.
- the invention is by no means restricted by the exemplary embodiment shown. It is self-evident that the application of the invention not only for rope couplings, but also for couplings with rods (e.g. towing rods), for any fastening devices for ships, aircraft, for lifting devices, for railway wagons (couplings), but also for transport brackets for machines or the like as well as Aid devices for mountaineers and sports can be used.
- rods e.g. towing rods
