Definitions

  • Chain link, chain link and energy chain as well as intermediate piece for an energy chain, with torsion-coupled locking means for connecting the cross bar and chain link
  • the invention relates to a link plate of an energy chain, a chain link of an energy chain, an energy chain and an intermediate piece for an energy chain.
  • Energy supply chains are often used when a movable component, in particular a component that essentially moves on predetermined tracks, has to be supplied, for example with electricity, water, consumables or the like.
  • lines must be routed from a fixed point to the component in such a way that the component can move along its predetermined movement paths without the lines being damaged.
  • An energy guide chain consists of chain links which are connected to one another in an articulated manner, the energy guide chain being moved along a predetermined path.
  • the lines in the energy chain are practically routed in a predetermined manner, so that the lines are exposed to very little, if any, wear.
  • a chain link has two link plates which define the lateral boundaries of the chain link and at least one crossbar which forms the upper and / or lower limit of the chain link.
  • the chain links are designed so that one chain link can be connected to at least one adjacent chain link and / or at least one end piece in order to build up the energy chain. In most cases, this connection takes place via corresponding connecting means, which are formed correspondingly in adjacent link plates.
  • Chain link and crossbar can be formed in one piece, for example made of a plastic, in particular injection molded, but it is just as common to design crossbars and chain links so that they can be releasably connected to one another.
  • a detachable connection of the chain link with at least one crossbar has the advantage that access to the lines is easy, so that insertion or removal of the lines from the chain and possible access to the lines for maintenance purposes is easily possible.
  • the chain link have a fastening means which is suitable and intended for the releasable connection of the chain link to a cross link.
  • the fastening means has at least one locking means.
  • at least one torsion element is provided. This is connected to the fastening means and a wall of the link plate in such a way that it can be deflected substantially about a longitudinal axis of the link plate. At least to release a crossbar, the at least one torsion element is twisted essentially around a longitudinal axis of the link plate.
  • the fastening element does not protrude beyond the edge of the chain link, so that an inadvertent loosening of a crossbar connected to the chain link is avoided.
  • Safety can also be further increased by the fact that the upper side of the crosspiece is essentially flush with the fastening element or lies above the fastening means.
  • the fastening means preferably has a tool engagement area into which a tool, for. B. a screwdriver, can be inserted. Using the tool, a torsional moment is introduced into the torsion element via the fastening means. If the torsional moment is sufficiently high, the fastening element is pivoted so that the crossbar is released.
  • the fastener is automatically returned to its rest position by the torsion element when the crossbar has been removed.
  • the usable cross section of an energy chain is also determined by the distance between the link plates.
  • the fastening means is arranged in a receptacle which extends at least from an inner wall in the direction of an outer wall of the chain link.
  • the receptacle and the fastening means are preferably dimensioned such that the fastening means is essentially completely integrated in the receptacle. This is not absolutely necessary.
  • at least one sealing means is formed above the inner wall. This is not critical if the locking means protrudes into the crossbar.
  • the receptacle in the wall of the link plate can also be designed in the form of an opening.
  • fastening means and the chain link are made in several pieces.
  • the fastener is preferably non-detachably connected to the link plate. It has corresponding fasteners which enable the fastener to be fastened to the chain link in the receptacle.
  • This can be, for example, barbs formed in the wall of the link plate in the area of the receptacle, which interact with appropriately designed means of the fastening means, hu concrete
  • torsion elements are provided on both sides of the fastening means, which are designed accordingly, so that these torsion elements partially protrude into the gaps formed in the wall of the link plate.
  • the multi-piece design of the link plate has the advantage that, if necessary, different fastening means can be used depending on the intended use.
  • one type of fastener can be used for different link plates if these link plates have receptacles of essentially the same design.
  • the fastening means can also be connected to the receptacle in a positive and / or non-positive manner.
  • the fastening means and the link plate are formed in one piece.
  • Such a one-piece design is particularly advantageous if the link plate is made of a plastic.
  • the wall and or the at least one fastening means are preferably made of at least one plastic, at least one elastomeric plastic, a renewable raw material and or metal.
  • the wall and the fastening means are made of one or more plastics, while the at least one Torsion element is formed from a metal.
  • Such a configuration is particularly advantageous if there is a risk of the torsion element breaking in the case of relatively thin walls of the link plate.
  • a chain link is known from WO 98/34050, which can be connected to a crossbar in such a way that the crossbar can be pivoted about a longitudinal axis of the chain link.
  • This has the advantage that, in the case of a chain link, the crossbar of one chain link while maintaining the connection to the other Chain link can be released. This ensures that the crossbar is not lost.
  • at least one swivel axis receiver is designed to receive a swivel axis of a crossbar and / or an intermediate piece.
  • the swivel axis holder and the fastening means represent functional units which are independent of one another, so that in the chain link according to the invention there is the possibility of connecting the chain link either with crossbars which are pivotable or not pivotable.
  • cross locking means are provided. This measure ensures that, in the case of an energy guide chain which is composed of chain links which have at least one chain link according to the invention, during operation of the energy guide chain, the crossbar does not detach from the chain link according to the invention.
  • the chain link according to the invention have longitudinal locking means which, when the chain link is connected to a crossbar, substantially prevent relative movement of the crossbar in a direction essentially parallel to the longitudinal axis of the chain link.
  • Allow chain link In order to prevent the applied torsional moment from exceeding a maximum permissible torsional moment, it is proposed that means for limiting a deflection of the fastening means are provided.
  • a chain link for an energy guide chain with two chain links, connected to one another by at least one transverse web is proposed that at least one chain link is designed according to one of Claims 1 to 11.
  • a crossbar interacts with at least one fastening means. It is advantageous here if at least one locking means interacts with a locking receptacle of the crossbar.
  • An embodiment of the chain link is preferred in which the locking means and locking receptacle can be connected to one another by a force fit and / or a form fit.
  • the locking receptacle is preferably formed in an end face of the crossbar.
  • a corresponding profiling of the crossbar can also be realized in the locking device.
  • the crossbar can then be designed as a profile.
  • An embodiment of the crossbar made of a metal or a plastic is preferred. The crossbar can be deflected from an extruded semi-finished product with the appropriate profile design.
  • a minimum force is required to release the crossbar and fastening means, in particular locking means and locking receptacle .
  • This minimum force can have different values depending on the design of the chain link and the use of the chain link.
  • longitudinal and or cross-locking receptacles are formed on the crossbar, which can be brought into engagement with the longitudinal and / or cross-locking means, in a form-fitting and or non-positive manner.
  • at least one pivoting means is formed on at least one connection side between the cross link and chain link on the cross link, which can be brought into engagement with the pivot axis receptacle.
  • the chain link can also be designed in such a way that at least one intermediate piece is provided, one side of which receives the connecting side of the crossbar and the other side has at least one pivoting means which can be brought into engagement with the pivoting axis receptacle of the chain link.
  • the chain link can also be an end link for an energy chain.
  • Such an end link has two link plates, each of which can have only one joint area.
  • the chain link can have a device by means of which the end link can be connected to a fixation on the stationary of the movable connection.
