For the tensioning chains of fabric drying machines, clip links which can be dismantled into two parts are known, each of which consists of one that forms the guide chain lower and one detachable therefrom, the upper one carrying the button latch and possibly the needle bar Part exist. This dismantling should allow the upper clip part, for example, for cleaning easy and quick to remove from finish smears from the lower chain part, without the chain part having to dismantle and expand yourself. Furthermore, with clip chains where the upper Clip part covers the lower chain part to protect against fiber fly, by removing the clip part the chain part can be easily exposed for lubrication. For these reasons it is desirable that the to be able to quickly loosen and reassemble both parts of each clip link.

The previous versions of two-part clip members use for the releasable connection of the Button trap and the chain part removable locking members such. B. one or more screws or Seeger rings or chain locks acting in the manner of Seeger rings, which are attached to the extended, The chain pins receiving the button latch or needle bar part are attached. The screw connections have the disadvantage that they can only be loosened with the aid of a wrench and that the nuts of the screws require a safety device that can be reused for repeated loosening and reassembly of the two-part Clip links are not permitted. The same goes for circlips or chain locks, which are also through Repeated loosening become unusable and must therefore be replaced. For this reason, you have to for the necessary frequent cleaning of the clip or pin bar part from finish smears, such as they arise especially when crease-proof finishing, do without the merchandise holder for cleaning lift off the chain part. Due to the inconvenience of separating and reuniting the parts, which either requires frequent replacement of the fasteners or their fuses, are the known closures for two-part clip or needle chain links meet the demands made on them not fair enough.

To eliminate the deficiencies inherent in the known closures for two-part clip links, suggests the invention provides a quick release fastener that allows the connection and separation of the upper and with a single handle. lower part of each Kluppcngliedes made possible without the aid of a tool and without the need for spare parts.

According to the invention, the upper one carrying the button latch and / or possibly the needle bar is used for this purpose

Part connected to the lower part forming the guide chain by spring action coupling bars, which are slidably or pivotably guided in the clip element and which are used for releasing and connecting The two clip parts can be made by hand against the spring action from the Kuppr without tools management position or can be moved into this under the action of the spring. The one that can be engaged and disengaged by hand Quick-release fastener uses coupling latches, one perpendicular to the direction of action of its springs mediate standing positive connection of the parts to be coupled together, so that the resilient Coupling row] from the power transmission of the wide clamping of the material web to the guide the rails of the clip chains are completely relieved.

For this positive connection, the part of the clip member carrying the button latch can have a Bar-shaped rear edge of the chain part reach behind and under, during the spring action standing, in the button latch part displaceably or pivotably arranged coupling latch on the \ 'order edge of the chain part reaching tongues below.

As a displaceable coupling cone, it is advisable to use two oppositely outwardly directed fork Roäuler are used, which are pressed apart by an interposed spring and thereby wall pieces of the two with their mouth Reach over parts of each clip link. A fork-like prong of each mouth stands over the side surfaces of the the clip part carrying the button latch as a pressure pin for actuating the coupling bolt to the outside in front, while the other prong of the fork mouth has a conical tightening surface for the mouth opening

Claims (4)

1 06 ensures that the clamp parts to be coupled are clamped together without play. A spring bar, which is held in the center of the clip part carrying the button latch, can serve as a coupling bolt which can be pivoted under the action of a spring. The arms of the spring bar on both sides reach for its actuation through slots in the side walls of the button latch part and reach under the tongues provided on the chain part of the clip link, which are provided with an inclined surface for the tight tightening of the clip parts against each other. In the drawing, two exemplary embodiments of a sonic fastener for two-part clip members according to the invention are shown. 1 shows a vertical section along line II in FIG. 2, FIG. 2 shows a cross section along line II-II in FIG. 1 through the clip body according to the first embodiment, and FIG. 3 shows a vertical section along line III III of FIGS. 4 and 4 show a horizontal section along the line IV-IV of FIG. 3 according to the second embodiment. The clip link is divided into an upper part 2 carrying the button latch 1 and, in the case of combined clip and needle chains, the needle bar (not shown) and a lower part 3 with the hinge pin 4 for the guide chain. The upper part 2 of each clip link engages with a projection 5 at its rear end under the strip-shaped rear edge 6 of the chain link part, which consists in a known manner of a C-shaped body 3 which expires in fork-shaped bearing eyes for the hinge pins 4 and connecting straps hinged thereon. The lower and rear mounts 5, 6 of the chain link part 3 through the upper clip link part 2 is supplemented by coupling bars 9, 10 under the action of a spring 8 to form a firm positive fit between the two parts 2, 3 of the clip link. The coupling bars 9, 10 consist of fork-shaped jaws that are pushed apart by the interposed spring 8. The upper prongs of each mouth protrude through openings in the side walls of the upper clip part 2 as pressure pins for the actuation of the clip member, while the lower, shorter prongs 11 of the fork mouth have a support surface 12 with which the parts 2, 3 to be coupled are firmly pressed onto one another. The picking up of the train of goods is transferred from the clamping point of the goods between the bracket table and the button trap via the rear support 5, 6 to the chain part 3, which is supported by a riveted sintered part 13 in the chain rail guide 14. To separate the upper clip link part 2 from the lower chain part 3, the two fork jaws 9, 10 are pressed together against the action of the spring 8 by grasping the upper clip link part with the hand until the lower teeth of the fork jaw release the tongues 7 of the chain part 3. By folding up the button latch part 2 around the rear edge 6 of the chain part 3, the upper part 2 can then be lifted freely from the lower chain part 3. The two parts 2, 3 can be connected to one another again by the reverse process. In the embodiment according to FIGS. 3 and 4, the connection is made in a similar manner. The upper clip link part 2 engages behind and here again engages with a projection 5 below the strip-shaped rear edge 6> of the chain part 3. The spring bar 16 is held against lateral displacement and against rotation with a loop 17 formed in its center in a recess 18 of a transverse wall 19 of the upper clip member part 2. The spring 16 extends outward through slots 20 in the side walls of the upper clip member part, so that the protruding, appropriately bent ends jo enable the spring 16 to be bent back into the dot-dashed position shown in FIG. 4 by the hand encompassing the clip body. In this way, in the same way as in the embodiment described above, the rear edge 6 of the upper part 2 can be removed from the lower chain part 3 by a folding movement by 3. In this embodiment, too, an inclined tightening surface 21 is provided on the tongues 14 ao to avoid play and to press the parts 2, 3 firmly against one another. To dismantle the clip link, the spring bar 16 is pushed forward until it is free from the tongues 14 in the slots 20 of the side walls of the upper clip link part 2 and then released from the chain part 3 by folding around the rear connection 5, 6 of the button latch part 2. The reconnection takes place in the reverse process. The button latch part 2 is hooked with the slightly raised front end with the projection S under the rear edge 6, then placed smoothly on the chain part 3 by pushing the spring rod 16 into the dot-dashed position shown in FIG of the tongues 14 the connection is restored.
