Abstract
The invention relates to a chain link for energy transmission chains, comprising link plates and cross links. At least one of said cross links can be detachably connected to the link plates by means of stop elements. The inventive chain link also has recesses in the opposite edge areas of the link plates, for receiving the ends of the cross links and the stop elements. The stop elements consist of projections and/or indentations and slides which are configured in the recesses and in the ends of the cross links and by which means the link plates can be pressure-connected to the cross link. The recesses (6) are covered on top by the longitudinal side edges (4, 5). The part of the slide (9) which exerts pressure on the cross link and the link plate (1) can be displaced along the top or bottom face of the cross link.
Description
CHAtN LINK FOR POWER TRANSMITTING CHAINS
The invention relates to a chain link for power transmitting chains of the type mentioned in the preamble of claim 1.
Such a chain link is known from DE-C1-41 21 433. Such chain links are connected to other identically configured chain links in a pivotal manner so as to form a power transmitting chain, the frame being formed by two sidebars and the two associated transverse webs and respectively serving to accommodate hoses and cables or the like. In the case of this known chain link, each recess extends over the full thickness of the sidebar and has arching-back undercut portions at a spacing from the sidebar edges, and the width of the recess when viewed with respect to the longitudinal direction of the sidebar is selected to be so great that the transverse strut can be displaced into these undercut portions when viewed with respect to the longitudinal direction of the sidebar. After such a displacement, a slide which is guided in a groove of the transverse strut can then lock in position in the area which becomes free during the displacement, between transverse web and sidebar, this groove being provided in a narrow side of the transverse web and extending in the longitudinal direction of the transverse web.
Because of the recess which extends over the whole thickness of the sidebar, and because of the large width of said recess, which width is required because of the transverse web displacement, this known chain link has the disadvantage that its stability is weakened in such a manner that the sidebar can easily be sheared-off in this region during the operation of the power transmitting chain.
The object of the invention resides in providing a chain link of the type mentioned in the preamble of the claim, which chain link has a greater stability for the sidebars.
The invention relates to a chain link for power transmitting chains of the type mentioned in the preamble of claim 1.
Such a chain link is known from DE-C1-41 21 433. Such chain links are connected to other identically configured chain links in a pivotal manner so as to form a power transmitting chain, the frame being formed by two sidebars and the two associated transverse webs and respectively serving to accommodate hoses and cables or the like. In the case of this known chain link, each recess extends over the full thickness of the sidebar and has arching-back undercut portions at a spacing from the sidebar edges, and the width of the recess when viewed with respect to the longitudinal direction of the sidebar is selected to be so great that the transverse strut can be displaced into these undercut portions when viewed with respect to the longitudinal direction of the sidebar. After such a displacement, a slide which is guided in a groove of the transverse strut can then lock in position in the area which becomes free during the displacement, between transverse web and sidebar, this groove being provided in a narrow side of the transverse web and extending in the longitudinal direction of the transverse web.
Because of the recess which extends over the whole thickness of the sidebar, and because of the large width of said recess, which width is required because of the transverse web displacement, this known chain link has the disadvantage that its stability is weakened in such a manner that the sidebar can easily be sheared-off in this region during the operation of the power transmitting chain.
The object of the invention resides in providing a chain link of the type mentioned in the preamble of the claim, which chain link has a greater stability for the sidebars.
This object is achieved with the features of claim 1.
It is apparent that the invention is realised in any event when sidebars with continuous openings or blind-bore openings for transverse web ends are involved, at least one projection member or one indentation being provided in the base or upper surface of said sidebars, said member or indentation preferably being connectable to a corresponding indentation or a projection member of the transverse web end in a form-locking manner and being securable by locking means. Because of the adjustable locking means, which are insertable between the transverse web ends and the receivers of the transverse web ends, these component parts are interconnectable in a non-displaceable, but detachable manner. The displacement of the locking means, which is effected in the longitudinal direction of the transverse web, may be accomplished, for example, by means of a screwdriver.
Because the longitudinal side edge is continuously closed on the upper surface, that is to say it does not have any indentations, recesses, grooves or the like orientated relative to the central longitudinal axis X of the sidebar, the sidebar has no usual intended breaking or bending locations along its longitudinal sides, the sidebar being weakened by said locations.
In consequence, the transverse web can be mounted on the locking web by its slot, so that a displacement in the longitudinal direction of the transverse web on the sidebar is no longer possible, while the transverse web can be locked on the sidebar in a vertical direction relative to the sidebar edge face by displacing the U-shaped locking body in the guide groove of the transverse web and introducing this body into the locking recess of the sidebar. Only a minimal amount of space is required for the sidebar recess to permit such a locking of the transverse web on the sidebar.
It is apparent that the invention is realised in any event when sidebars with continuous openings or blind-bore openings for transverse web ends are involved, at least one projection member or one indentation being provided in the base or upper surface of said sidebars, said member or indentation preferably being connectable to a corresponding indentation or a projection member of the transverse web end in a form-locking manner and being securable by locking means.

Because the longitudinal side edge is continuously closed on the upper surface, that is to say it does not have any indentations, recesses, grooves or the like orientated relative to the central longitudinal axis X of the sidebar, the sidebar has no usual intended breaking or bending locations along its longitudinal sides, the sidebar being weakened by said locations.
In consequence, the transverse web can be mounted on the locking web by its slot, so that a displacement in the longitudinal direction of the transverse web on the sidebar is no longer possible, while the transverse web can be locked on the sidebar in a vertical direction relative to the sidebar edge face by displacing the U-shaped locking body in the guide groove of the transverse web and introducing this body into the locking recess of the sidebar. Only a minimal amount of space is required for the sidebar recess to permit such a locking of the transverse web on the sidebar.
The locking body may be guided in the guide groove and in the locking recess with a snug fit in order to prevent it sliding from the locked position.
According to an additional embodiment of the invention, the locking body is provided with locking means which secure this body on the transverse web andlor on the sidebar, at least in its locked position, and retain it even more securely in this locked position.
According to a simple, additional embodiment of the invention, the shank ends of the locking body are provided on the internal edges with locking projections, which engage in complementary locking recesses of the transverse web.
According to an additional embodiment of the invention, the body is provided with control means. The locking body can be displaced more easily with these control means.
According to a simple, additional embodiment of the invention, the locking body is provided centrally with an adjustable opening as the control means in its bottom part.
According to a simple, additional embodiment of the invention, transverse strut and sidebar edge have adjustable recesses over the displacement path of the adjustable opening, the width of the adjustable recesses corresponding substantially to the length of the adjustable opening.
The weakening of the sidebar, formed by recesses, is thereby minimised.
The invention is now explained more fully with reference to one embodiment. In the drawing:

Fig. 12 is a cross-sectional view taken along the line XII-XII of Fig. 11; and Fig. 13 is a plan view of detail A of Fig. 11.
The sidebar 1, illustrated in Fig. 1, of a chain link for a power transmitting chain is a flat, elongate plastics material body, which is rounded at the ends and is provided, in its end regions 2 and 3, with coupling means for the rotatable coupling of additional sidebars of additional chain links.
At each of the oppositely situated longitudinal side edges 4 and 5, the sidebar 1 is provided centrally with a through-recess 6 or 6' respectively, which recesses are used for the lockable and detachable accommodation of the ends of two transverse struts, which are not illustrated in Fig. 1.
The other ends of the transverse struts are secured in a similar manner in a sidebar of the chain link, which sidebar lies parallel to the sidebar 1.
In consequence, a frame is created, in which power transmitting lines may be accommodated. The following description relates only to the dash-dot detail A; the same applies to the other engagement points (like 6'). As is apparent from Fig. 1, the recess has only a small width and, furthermore, the longitudinal edge 4 in the region of the recess is rectilinear and continuous, so that the weakness in the stability of the sidebar 1, caused by the recesses 6 and 6', is minimal. In consequence, the risk of the sidebar 1 shearing-off between the recesses 6 and 6' is also slight.
The cross-sectional view, illustrated in Fig. 2, in the region of detail A
illustrates the recess 6, which is limited to one part of the edge region. A
partial region 7 of the recess 6 is open upwardly and inwardly to accommodate the end, illustrated in Fig. 3, of a separate transverse strut 8 and a locking body 9 inserted in said strut (Figs. 3, 8 and 9). An additional partial region 10 of the recess 6 serves as an adjustable opening, by. mearas of which two shoulder portions, such as the shoulder portion 11, are created.
Furthermore, the recess 6 includes a partial region 12, which forms a passage through the sidebar 1. An edge portion 13 of the sidebar 1 is thereby maintained, so that forces, which act outwardly from the central longitudinal axis X and towards the transverse web 8, are absorbed in optimum manner.
A locking web 14 is disposed on the base of the recess 6 and is used to lock the transverse strut 8 on the sidebar 1 in the longitudinal direction of the transverse strut.
The partial region 12 of the recess 6, which is configured as a passage, is advantageous for reasons relating to injection moulding. Slides for the joint moulding of the recess 6 can in fact be guided through this partial region. In contrast to the illustrated height of the partial region 12, the height may also be restricted to the height of the locking web 14, so that the edge portion 13 would be reinforced.
The end of the transverse strut 8, illustrated in Fig. 2, is a parallelepiped body having a plate-like extension 15 attached to the base of this body, an adjustable opening 16 which lies to the side of this extension and by means of which two shoulder portions, such as the shoulder portion 17, are formed, a guide groove 18 which is shown by dashed lines and extends around the transverse strut end parallel to the upper surface of the transverse strut, and a slot 19 which is situated at the base and is adapted to the locking web 14. The locking body 9 is guided in the guide groove 18.
This locking body is illustrated more fully (and on an enlarged scale) in Figures 8 and 9. It is a plate- and U-shaped body formed from a bottom part 20 and two portions 21 and 22 and is thus configured as a slide, which may be slid-in from the inside or outside of the sidebar. Centrally, the bottom part 20 has an adjustable opening 23, which is configured as an elongate slot.
The ends of the portions 21 and 22 are provided on their internal edges with locking projections 24 and 25 respectively which, according to Fig. 5, may engage in complementary locking recesses 26, 27 or respectively 28, 29 of the transverse strut 8 in the end positions of the locking body 9.
The length of the recess 6, of the partial region 12 and of the locking web 14 is apparent in Fig. 4. This length is adapted to the width of the locking body 9 and of the transverse strut 8.
The length of the adjustable recess 10 in the sidebar 1 and of the shoulder portions 11 and 11', thereby formed, is apparent from Fig. 6. The length of the adjustable recess 10 is so selected that it substantially corresponds to that of the adjustable opening 23. The length of the adjustable recess 16 in the end of the transverse strut 8 is apparent from Fig.
7. The length of the adjustable recess 16 is equally so selected that it corresponds substantially to that of the adjustable opening 23. The lengths of the adjustable recesses 10 and 16 are preferably identical.
Fig. 10 illustrates how the transverse web 8 is gradually inserted into the recess 6 with the slid-in locking body 9. As indicated, the extension 15 is slid under the shoulder portions 11 and 11', then the transverse strut 8 is lowered so that the locking web 14 slides into the slot 19, and finally the locking body 9 is displaced beneath the shoulder portions 11 and 11'. This displacement of the locking body 9 may be effected with a tool, a screwdriver for example, which is inserted into the adjustable opening 23. As is apparent, the thickness of the extension 15 and the thickness of the locking body 9 together correspond to the height from the bottom of the recess 6 to the shoulder portion 11. In such case, the height of the locking web 14 corresponds to the thickness of the locking body 9.
These dimensions may also be seen in Figs. 11, 12 and 13, which indicate the locked position of the transverse strut 8 in the sidebar 1 by~
means of the locking body 9. Furthermore, the co-operation between the adjustable recesses 10 and 16 is apparent from Fig. 13.
In consequence, the transverse strut 8 is prevented from being displaced in the longitudinal direction of the transverse web by means of the locking web 14 and the slot 19, on the one hand, and is prevented from being displaced in a direction perpendicular to the sidebar edge 4 by means of the locking body 9, on the other hand. The locking can be released again by an appropriate displacement of the locking body 9.

Fig. 12 is a cross-sectional view taken along the line XII-XII of Fig. 11; and Fig. 13 is a plan view of detail A of Fig. 11.
The sidebar 1, illustrated in Fig. 1, of a chain link for a power transmitting chain is a flat, elongate plastics material body, which is rounded at the ends and is provided, in its end regions 2 and 3, with coupling means for the rotatable coupling of additional sidebars of additional chain links.
At each of the oppositely situated longitudinal side edges 4 and 5, the sidebar 1 is provided centrally with a through-recess 6 or 6' respectively, which recesses are used for the lockable and detachable accommodation of the ends of two transverse struts, which are not illustrated in Fig. 1.
The other ends of the transverse struts are secured in a similar manner in a sidebar of the chain link, which sidebar lies parallel to the sidebar 1.
In consequence, a frame is created, in which power transmitting lines may be accommodated. The following description relates only to the dash-dot detail A; the same applies to the other engagement points (like 6'). As is apparent from Fig. 1, the recess has only a small width and, furthermore, the longitudinal edge 4 in the region of the recess is rectilinear and continuous, so that the weakness in the stability of the sidebar 1, caused by the recesses 6 and 6', is minimal. In consequence, the risk of the sidebar 1 shearing-off between the recesses 6 and 6' is also slight.
The cross-sectional view, illustrated in Fig. 2, in the region of detail A
illustrates the recess 6, which is limited to one part of the edge region. A
partial region 7 of the recess 6 is open upwardly and inwardly to accommodate the end, illustrated in Fig. 3, of a separate transverse strut 8 and a locking body 9 inserted in said strut (Figs. 3, 8 and 9). An additional partial region 10 of the recess 6 serves as an adjustable opening, by. mearas of which two shoulder portions, such as the shoulder portion 11, are created.
Furthermore, the recess 6 includes a partial region 12, which forms a passage through the sidebar 1. An edge portion 13 of the sidebar 1 is thereby maintained, so that forces, which act outwardly from the central longitudinal axis X and towards the transverse web 8, are absorbed in optimum manner.
A locking web 14 is disposed on the base of the recess 6 and is used to lock the transverse strut 8 on the sidebar 1 in the longitudinal direction of the transverse strut.
The partial region 12 of the recess 6, which is configured as a passage, is advantageous for reasons relating to injection moulding. Slides for the joint moulding of the recess 6 can in fact be guided through this partial region. In contrast to the illustrated height of the partial region 12, the height may also be restricted to the height of the locking web 14, so that the edge portion 13 would be reinforced.
The end of the transverse strut 8, illustrated in Fig. 2, is a parallelepiped body having a plate-like extension 15 attached to the base of this body, an adjustable opening 16 which lies to the side of this extension and by means of which two shoulder portions, such as the shoulder portion 17, are formed, a guide groove 18 which is shown by dashed lines and extends around the transverse strut end parallel to the upper surface of the transverse strut, and a slot 19 which is situated at the base and is adapted to the locking web 14. The locking body 9 is guided in the guide groove 18.
This locking body is illustrated more fully (and on an enlarged scale) in Figures 8 and 9. It is a plate- and U-shaped body formed from a bottom part 20 and two portions 21 and 22 and is thus configured as a slide, which may be slid-in from the inside or outside of the sidebar. Centrally, the bottom part 20 has an adjustable opening 23, which is configured as an elongate slot.
The ends of the portions 21 and 22 are provided on their internal edges with locking projections 24 and 25 respectively which, according to Fig. 5, may engage in complementary locking recesses 26, 27 or respectively 28, 29 of the transverse strut 8 in the end positions of the locking body 9.
The length of the recess 6, of the partial region 12 and of the locking web 14 is apparent in Fig. 4. This length is adapted to the width of the locking body 9 and of the transverse strut 8.
The length of the adjustable recess 10 in the sidebar 1 and of the shoulder portions 11 and 11', thereby formed, is apparent from Fig. 6. The length of the adjustable recess 10 is so selected that it substantially corresponds to that of the adjustable opening 23. The length of the adjustable recess 16 in the end of the transverse strut 8 is apparent from Fig.
7. The length of the adjustable recess 16 is equally so selected that it corresponds substantially to that of the adjustable opening 23. The lengths of the adjustable recesses 10 and 16 are preferably identical.
Fig. 10 illustrates how the transverse web 8 is gradually inserted into the recess 6 with the slid-in locking body 9. As indicated, the extension 15 is slid under the shoulder portions 11 and 11', then the transverse strut 8 is lowered so that the locking web 14 slides into the slot 19, and finally the locking body 9 is displaced beneath the shoulder portions 11 and 11'. This displacement of the locking body 9 may be effected with a tool, a screwdriver for example, which is inserted into the adjustable opening 23. As is apparent, the thickness of the extension 15 and the thickness of the locking body 9 together correspond to the height from the bottom of the recess 6 to the shoulder portion 11. In such case, the height of the locking web 14 corresponds to the thickness of the locking body 9.
These dimensions may also be seen in Figs. 11, 12 and 13, which indicate the locked position of the transverse strut 8 in the sidebar 1 by~
means of the locking body 9. Furthermore, the co-operation between the adjustable recesses 10 and 16 is apparent from Fig. 13.
In consequence, the transverse strut 8 is prevented from being displaced in the longitudinal direction of the transverse web by means of the locking web 14 and the slot 19, on the one hand, and is prevented from being displaced in a direction perpendicular to the sidebar edge 4 by means of the locking body 9, on the other hand. The locking can be released again by an appropriate displacement of the locking body 9.
