text: fig2 shows a side view and fig2 a top view of a plate link chain 1 in accordance with the state of the art , with a two - plate connection . the basic construction of plate - link chains and toothed plate - link chains and the terms used in describing the exemplary embodiments in accordance with the invention will be explained on the basis of the structures shown in fig2 and 22 . the exemplary embodiments will be described using the example of a plate - link chain having a two - plate connection , but they are equally applicable to a plate - link chain having a three - plate connection . plate link chain 1 includes a large number of plates 2 and opposed plates 2 ′. plates 2 and opposed plates 2 ′ are arranged alternately , in a transverse direction of chain 1 , and are combined into a hinge joint with hinge joint pins 4 . consequently both ends of a plate 2 are connected to one or two opposed plates 2 ′ by means of a hinge joint , and , correspondingly , both ends of an opposed plate 2 ′ are connected to one or two plates 2 by a hinge joint . the hinge joint pins 4 can be in one piece , but are preferably in two pieces , with a rocker member 5 being associated with each of the plates 2 and rolling on a rocker member 5 ′ associated with the opposed plate 2 . in addition , rocker members 5 , 5 ′ each have a roller profile 7 and 7 ′ respectively , with which they can roll on or slide against each other . the roller profiles 7 , 7 ′ can be identical or different . the plates 2 and opposed plates 2 ′ are stacked transversely to the chain running direction l ( that is identified by an arrow with the reference label l ), so that an overlapping opposed plate 2 ′ is positioned between two hinge joint pins 4 that are arranged side - by - side and perpendicular to the running direction l . similarly , a plate 2 is positioned between and overlaps two opposed plates 2 ′ that are side by side transversely , relative to the running direction . of course , that does not apply to the plates 2 or opposed plates 2 ′ that are located on the outside , transversely to the running direction 2 , which have a neighboring plate on only one side . the sets of plates 2 formed as described above ( also referred to as plate stacks ) form a chain link 8 by sets . correspondingly , the sets of opposed plates 2 ′ form a chain link 8 ′ by sets . in the illustrated example the plates 2 and opposed plates 2 ′ can be identically formed parts , a differentiation between plates 2 and opposed plates 2 ′ being recognizable only by the arrangement in the chain . the following description will therefore only refer to plates 2 , because they are identical to the opposed plates 2 ′ except for the arrangement in sets . fig2 shows a plate set of three plates 2 and two opposed plates 2 ′; but it is also possible to provide plate sets with any other number of plates 2 and opposed plates 2 ′. in the case of a toothed plate - link chain , the plates 2 are each provided with plate teeth 9 , as can be seen in fig2 . in the case of a plate - link chain for use in a cvt transmission , for example , the plate teeth 9 are not present . with the plate teeth 9 , plate link chain 1 can mesh with a toothed part , for example a gear . the spacing between plates 2 and opposed plates 2 ′ is such that when the chain is extended a uniform spacing results overall between plate teeth 9 . the opposed plates 2 ′ are also provided with plate teeth 9 , so that all of the plates and opposed plates are provided with plate teeth 9 . but it is likewise also possible to provide either only plates 2 or opposed plates 2 ′ with two plate teeth 9 , or to provide plates 2 and opposed plates 2 ′ each with only one plate tooth 9 . the plate sets are closed on both sides by guide plates 10 . fig1 shows an embodiment of a guide plate 10 in accordance with the invention with receiving openings 11 for receiving rocker members 5 , 5 ′. the guide plates 10 include a main body 15 having upstanding legs 12 , on each of the outer ends of which there is provided a bent end 13 . between the receiving openings 11 an opening 14 is formed in main body 15 , which also includes a downwardly - extending lobe 16 facing away from legs 12 . fig2 shows guide plate 10 in accordance with the invention installed in a plate link chain 1 . guide plate 10 is part of a plate set 8 or 8 ′, as was described relative to fig2 and 22 , and is firmly connected to the associated rocker members 5 , 5 ′. fig3 shows a portion of toothed plate - link chain 1 in a side view and in a bowed or bent position , in which the bend is away from the teeth . as shown , the underside of bent ends 13 are resting on the plate stops 17 of an adjacent plate 2 . fig5 shows a first exemplary embodiment of a toothed plate 2 . 1 in accordance with the invention . the main body 15 of toothed plate 2 . 1 includes receiving openings 11 for pairs of both interacting rocker members 5 , 5 ′ of two different plate sets . positioned at each of the ends 18 and 18 ′ are lugs 19 and 19 ′, which extend from the main body 15 laterally in reference to the running direction l of the chain . fig6 shows a detail of a plate - link chain with a toothed plate 2 . 1 in accordance with fig5 . the series of toothed plates 2 . 1 positioned one after the other in the running direction l of the chain are positioned immediately beside the series of guide plates 10 . lugs 19 and 19 ′ each engage an opening comparable to the opening 14 in guide plates 10 shown in fig1 . fig7 shows a bent position of a portion of toothed plate - link chain 1 in accordance with fig6 , with toothed plate - link chain 1 bent in the direction of the teeth . in that position the lugs 19 do not contact guide plate 10 . fig8 shows a position of the toothed plate link chain in accordance with fig7 bent in the opposite direction , hence in the direction of the plate top 17 . in that position the lugs 19 contact opening 14 of the guide plates and thus prevent further bending . fig9 shows a second exemplary embodiment of a toothed plate 2 . 2 in accordance with the invention . toothed plate 2 . 2 will be described only in terms of the differences from the embodiment shown in fig5 . instead of a lug 19 or 19 ′, toothed plate 2 . 2 has side flanks 20 and 20 ′. fig1 shows a portion of a plate - link chain 1 with toothed plates 2 . 2 in accordance with fig9 . the manner of operation of the side flanks is illustrated in fig1 and 12 . fig1 shows the straight position of the chain , while fig1 shows the chain in a bent position with bending in the direction of the plate tops 17 . in the position in accordance with fig1 , the side flanks 20 and 20 ′ of adjacent toothed plates contact each other and thus prevent further bending of plate - link chain 1 . fig1 shows a third embodiment of a toothed plate 2 . 3 in accordance with the invention . wings 21 and 21 ′ extending in the running direction l of the chain are provided as a bend stopping means . wings 21 and 21 ′ abut against adjacent pins 4 or rocker members 5 , 5 ′ when plate - link chain 1 bends . fig1 shows a portion of a plate - link chain 1 with toothed plates 2 . 3 in accordance with the invention . toothed plates 2 . 3 are positioned within the group of plates in such a way that in the longitudinal series of plates in which the toothed plates 2 . 3 are positioned , a pin 4 or a combination of rocker members 5 and 5 ′ ( which can be referred to collectively as pin 4 in accordance with fig1 ) that extend through other adjacent plates do not pas through toothed plates 2 . 3 . wings 21 and 21 ′ can abut rocker members 5 , 5 ′ when toothed plate - link chain 1 bends in accordance with the illustration in fig1 . fig1 shows how the wings 21 and 21 ′ of adjacent toothed plates 2 . 3 abut against adjacent rocker members 5 , 5 ′ when toothed plate - link chain 1 bends . fig1 and 18 show a fourth exemplary embodiment of a toothed plate 2 . 4 in accordance with the invention . a bent - over wing 22 is positioned at plate top 17 as a stopping means . bent - over wing 22 extends over only part of the length of plate top 17 , and it has a width at starting end 23 that has a width that corresponds to the width 25 of the main body 15 of toothed plate 2 . 4 . on a contact face 24 , bent - over wing 22 is wider than at starting end 23 , so that its width 26 in the region of contact end 24 is greater than the width 25 of toothed plate 2 . 4 . the region of plate top 17 that is not overlaid by bent - over wing 22 has a stopping surface 27 that can come into contact with the underside of a bent - over wing 22 of an adjacent toothed plate 2 . 4 . at contact end 24 . fig1 shows a portion of a plate - link chain 1 with toothed plates 2 . 4 in accordance with fig1 and 18 . toothed plates 2 . 4 are all installed in toothed plate - link chain 1 in the same orientation . fig2 illustrates the manner of operation of the stopping means of the toothed plate embodiment shown in fig1 and 18 . if the toothed plate - link chain is bent in the direction of the plate top 17 , the bent - over wings 22 strike the contact surface 27 of the adjacent toothed plates . although particular embodiments of the present invention have been illustrated and described , it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit of the present invention . it is therefore intended to encompass within the appended claims all such changes and modifications that fall within the scope of the present invention .
