Device for leading and holding electrical lines in a swivel region of doors
View Patent ↗A device, which reliably guarantees the protection of electric cables that are located in the pivoting region of doors against cable damage or the splitting of an insulating layer includes a device for guiding and fixing electric cables in the pivoting region of doors. The device has first and second tubular sections, each having a sleeve region that is bent at a right angle and a substantially cylindrical cross-section. Both sleeve regions are interconnected such that they can rotate in relation to one another.
1. A device for leading and holding electrical lines in a swivel region of doors, the swivel region of a door being a location at which a door pivots about a pivot axis relative to a door frame, the device comprising:
first and second tubular portions each having a respective sleeve region shaped in the form of a crank, said sleeve regions being joined together rotatably and rotating with respect to one another, said first tubular portion being securable to a door and said second tubular portion being securable to a door frame on which the door is pivotally mounted, said first and second portions having a lead-through region, the lead-through regions of said first and second portions together providing a passage through which at least one electrical line can be passed for extending the at least one electrical line to and between the door and the door frame, said sleeve region of said second portion having an interior with a substantially constant diameter and said sleeve region of said first portion having a step within said interior of said first portion keeping said lead-through region through said first and second portions substantially free of diameter changes; and
elements preventing axial shifting of said sleeve region of said second portion disposed at said sleeve region of said first portion and wherein said sleeve region of said first portion has one extent forming an open end of said first portion and another extent extending from said one extent, said one extent of said sleeve region of said first portion having an inner diameter relatively larger than the inner diameter of said other extent of said sleeve region of said first portion, said one extent of said sleeve region of said first portion receiving said sleeve region of said second portion inserted therein so that said one extent of said sleeve region of said first portion surrounds said sleeve region of said second portion, the inner diameter of said other extent of said sleeve region of said first portion being substantially the same as the inner diameter of said sleeve region of said second portion, and said step of said sleeve region of said first portion forming a transition from said one extent of said sleeve region of said first portion to said other extent of said sleeve region of said first portion such that the extent of the lead-through region formed by said other extent of said sleeve region of said first portion and said sleeve region of said second portion is substantially free of diameter changes.
2. The device according to claim 1 , where in said sleeve region of said first portion surrounds a substantial part of said sleeve region of said second portion.
3. The device according to claim 1 , wherein:
said sleeve regions define a rotation axis coinciding with the pivot axis of the respective door on which the device is mounted.
4. The device according to claim 1 , further comprising at least one axial stopping element disposed at said sleeve region of said second portion and preventing an axial shift of said sleeve region of said first portion.
5. The device according to claim 1 , wherein said first portion is securable to a door of a household appliance and said second portion is securable to a door frame of a household appliance.
6. The device according to claim 5 , wherein said first portion is securable to a door of a selected one of the group consisting of dishwashers and washing machines and, second portion is securable to a door frame of the selected one of the group consisting of dishwashers and washing machines.
