  • the guide webs 67, 68 of the clamping strip 60 caught between the support plate 57 and the transverse webs 59a, 59b of the sliding block 58 and possibly braced, whereby the chain holder 1 is slidably guided relative to the clamping strip 60 or is fixed thereto.
  • the receiving groove 70 of the clamping strip 60 of the guide block 79 according to Fig. 17, 18 used herein.
  • the fastening screw 82 which also extends through the slot 75 of the clamping strip 60 and the slot 78 of the reinforcing plate 62 extends. The downwardly projecting from the reinforcing plate 62 end portion of the fastening screw 82 is screwed into a further sliding block 86.
  • the sliding block 86 can be accommodated in a guide groove, for example, a clamping table.
  • a guide web of the guide groove of the clamping table can be clamped between the sliding block 86 and the underside of the reinforcing plate 62 Fig. 19 is shown, according to the receiving groove 69, a guide block with a further fastening screw, which is screwed into a further sliding block be used.
  • both the grooves 69, 70 associated with sliding blocks 86 are arranged in the same guide groove of the clamping table. But it is also possible that they are arranged in different guide grooves of the clamping table, in which case the longitudinal axis of the clamping strip 60 is inclined or even forms a right angle to the guide grooves of the clamping table.
  • Fig. 21 is a Aufspannance 60 guided in the grooves 69, 70 guided guide blocks 79a, 79b, 79c and associated attachment letters 82a, 82b, 82c and sliding blocks 86a, 86b, 86c fixed to a chuck table.
  • Two support bodies 89a, 89b are displaceable guided in the guide groove 63 of the clamping strip 60 or fixed therein.
  • the support bodies 89a, 89b have here V-shaped inclined support surfaces 90a, 90b, in which case the support surface 90 form an angle of 150 ° to 170 °, depending on the object to be supported 91.
  • On one side of the object (in Fig. 21 left) is corresponding Fig. 19 and Fig.
  • a chain holder 1 with securing element 28 is supported, which hold a link chain 52.
  • the link chain 52 is guided over the curved upper surface of the object 51 and abutted in the end region on the other side of the object 91 (in FIG Fig. 21 right) hinged to an end portion of a clamping lever 52.
  • the clamping lever 52 is part of a clamping lever unit 93, as this example of one of the publications DE 103 26 702 B4 .
  • EP1 955 816 A2 and EP 2 001 638 B1 is known.
  • the clamping lever 92 forms a pivot axis of the clamping lever 92 vorutilisede pivot pin 94, with which the clamping lever 92 in the guide groove 63 of the clamping bar 60 or a housing of the clamping lever unit 93, which in turn guided in the clamping strip 60, supported and / or fixed can be guided. Screwing a clamping bolt 95 in which the articulation of the link chain 52 facing away from the clamping lever 92 end portion leads to a pivoting of the clamping lever 92 (in Fig. 21 counterclockwise), whereby the clamping force in the link chain 52 can be increased.
  • the chain holder 1 is made of a flat material or a round material, in which case, for example, the geometry of the flat material or round material may correspond to the cross section in the region of the thickening 26.
  • the material 42 CrMo S4 can be used here. The corresponding applies to the securing element 28, the bearing body 37th
  • the inventive design of the components allows the immediate arrangement of the chain holder 1, for example, with the internal thread 25 or the threaded bolt 27, on a guide groove of a clamping table with a nut to be screwed. But it is possible that (as shown or in other combinations) between the chain holder 1 and the guide groove of the clamping table further fixed components or other degrees of freedom providing components are interposed. These are, for example, the bearing body 37 and / or the clamping strip 60. It is understood that other components can be interposed. In addition, an attachment of the chain holder 1, possibly with other components, on a support other than a clamping table, so for example on a vertical wall, a vertical, held on a chuck holder u. ⁇ .
  • the use of the chain holder is not limited to use in conjunction with a clamping lever unit, but rather any other clamping devices can be used.
  • the receptacle 5 facing away from the backbone 54 is referred to as “upstream recording”, while the other receptacle 6 is referred to as “downstream recording”.
  • the securing element 28 is designed as a securing sleeve 99.
  • the locking sleeve 99 has a (open-edged or edge-closed) cross-section such that the locking sleeve 99 in an assembly and disassembly 100, which is oriented parallel to the connecting axis 18, on the chain receiving portion 4 of the chain holder 1 can be pushed or pushed it down.
  • a through-passage 101 of the securing sleeve 99 has an extent in the height direction 97 in this case, in that, when the bearing surface 102 of the chain holder 1 facing away from the receivers 5, 6 bears against an inner surface 103 of the securing sleeve 99, there is a minimal gap between an inner surface 104 which is arranged on the side of the securing sleeve 99 opposite the inner surface 103 and the link chain 52 105 remains so small that overcoming the gap 105 through the chain links and / or the joint body 50, 51, the link chain still positively engages the receptacle 5, 6, which for the illustrated embodiment by conditioning at least to the end of the Fortsuits 14, 17 takes place.
  • the link chain 52 is thus between the chain holder 1 and the locking sleeve 99 in the in Fig. 22 captured locking position of the locking sleeve 99 caught, whereby an undesirable escape of the link chain 52 is avoided. Rather, for removal of the link chain 52 from the chain holder 1, the securing sleeve 99 must be pushed down by the chain holder 1, whereby the link chain 52 with the joint bodies 50, 51 can be completely removed from the exceptions 5, 6 and from the chain holder 1.
  • the locking sleeve 99 is formed separately from the chain holder 1.
  • the chain holder 1 extends with the connecting axis 18 vertically upwards, with only a component of the connecting shaft 18 can extend upwards for another clamping situation.
  • the locking sleeve 99 is applied downward in the secured operating position.
  • the removal of the link chain 52 from the chain holder 1 can be made possible.
  • a securing member 106 may be formed as an extension 106a of the chain holder 1, in which the locking sleeve 99 rests in the secured operating position. It is also possible that on both sides in mounting and dismounting direction 100 a securing member 106a, 106b is provided in the form of an extension, for the disassembly preferably targeted by the user a predetermined position of the locking sleeve 99 relative to the chain holder 1 and thus the securing member 106b must be brought about. Only schematically is in Fig.
  • securing member 106c a chain over which the locking sleeve 99 captive, but held with sufficient degree of freedom to the chain holder 1. It is entirely possible that a contact surface of a securing element 28, which a lifting of the joint chain 52 blocked from the receptacles 5, 6, otherwise via a hinge connection or a pivoting arm or even a mountable connection such as by means of a pen u. ⁇ . Is held on the chain holder 1.
  • Optional securing members 106 are in Fig. 22 shown in dashed lines.
