PROTECTOR CONDUIT ENTRY
The present invention refers to a cable lead-through device penetrating a substantially horizontal wall, e.g. a boat deck or a floor where water or other liquid can be present on the floor.
For such cable lead-through devices it has earlier been used a so called goose-neck, i.e. a tube, which is welded around a hole in the deck or the like and which extends upwards before it opens in a crutch-shaped bent down portion, with the opening situated above the level of the deck, but below the highest part of the tube.
In later years it has been developed a deck lead-through device for cables, at which is used a member in form of a two-part split, straight tube. A hole is drilled in the deck for this tube and which has a dimension corresponding that for the tube, and the tube is thereupon fitted in the hole with a tube part passing through the hole and with flange parts on the upper side and on the lower side of the deck. Over this tube lead-in then is positioned a cover, which on one long side is attached below a separate ledge which is screwed to the deck, whereas the cover on the other long side is attached to the deck by means of screws. The cover seals off against the deck around the tube. The cables are led in through side openings in the cover and extend like the cables in the goose-neck in a bend upwards, thus that the tube opening is situated above the deck.
The drawback with this solution is that the size of and the position for the hole which is wanted/needed to be made in the deck is determined by the tube dimension, which means that it often is necessary to make a substantially bigger hole than what is required for the cables in question. At the same time it is necessary to position the lead-through
exactly over the position where the cables shall be fitted below the deck.
The purpose of the present invention is to provide a new, protected lead-through of this type, which has not the drawbacks referred to above, but which in a simple and appropriate manner gives an appropriate protection independent of the position for the lead-through as well as the position for a unit situated therebelow and to which connection shall be done, and this is obtained in that the lead-through has been given the design defined in the characterizing part of the accompanying claim 1.
Hereinafter the invention will be further described with reference to a not limiting embodiment shown in the accompanying drawing .
Fig. 1 shows in side view a lead-through device in accordance with the invention Fig. 2 is a view from above of the device according to Fig.
1, and
Fig. 3 is an end view of the device according to Fig. 1 and
2.
In the accompanying drawing figures is illustrated a device 1 in accordance with the invention, and which in accordance with Fig. 1 incorporates a tubular body 2, which is provided on a planar plate 3 integral therewith. The plate 3 is preferably provided with a number of through-holes 7 or hole notches, which preferably can be distributed towards the outer plate edges for attachment of the plate to the planar base by means of screws. It is however also possible to glue the plate directly to the base, whereby it might be possible to refrain totally from using the holes (not shown) .
By such a solution, it is possible to make a hole in a boat deck below the plate 3 exactly as big as is required in the
separate case, i.e. everything from essentially smaller than the tube 2, to a dimension which just can be accommodated within the outer edges of the plate 3. At the same time it is possible to locate the plate where it is desired, without being bound to the exact position where the cables shall be used below the deck, as they might be led in transversely from the tube 2. It is also possible to position the plate over a existing hole in the deck, thus that this older hole is completely covered by the plate 3 or is partly covered by the plate and is partly situated below the tube 2.
As can be seen particularly from Fig. 2, the plate 3 is provided with two attachment screws 4 at opposite corners of a longitudinal side, whereas at the opposite longitudinal edge of the plate is provided an edge flange 5 which is bent upwards .
Together with the plate 3, which is equipped with a tube 2, thereupon is used a (not shown) overlaying cover of substantially the same design as at the earlier solution, whereby however no separate ledge is required but one longitudinal side of the cover can be inserted below the flange 5, whereas the cover at the opposite side is provided with through-openings, which fit over the attachment screws 4 in the plate 3, and which together with locking nuts can be used for locking the cover in closed position, which cover covers the entire plate 3 (the cover 3 is not shown) . When the cover later on is opened, the bent over edge ledge 5 and the edge of the cover projecting therebelow, function as a hinge therefore.
At appropriate positions, the plate 3 is provided with stampings 6, the purpose of which is to form attachment points for affixing of cable or bundles of cables, e.g. with cable belt.
In the embodiment shown the plate 3 is furthermore provided with notches 8 at the short sides, by means of which it is possible to facilitate the insertion of the cable from the side of the plate, whereby it e.g. also is possible to make depressions in the base below the edge of the cover in order to give space for bundles of cables, or even to position the plate 3 somewhat raised over the base on spacing members.
When fitting the lead-through device according to the invention it thus is possible to chose one or one of a smaller number of standard dimensions, with a certain desired diameter of the tube 2 forming part thereof, independent of which size (smaller or similar) which is required for the members (cables) , to be led therethrough. The underlaying hole in the base, such as the boat deck, can be made exactly in accordance with the dimensions required for the volume of the cables and the like, which are to be led therethrough. The lead-through device can be positioned where it will be best situated, i.e. it is not necessary that the tube 2 is positioned exactly above the hole in the deck, and it is also possible to use the device for earlier existing holes or contactors, which have sizes and/or positions, which do not coincide with those for the lead-through device, and in this manner the flexibility of the device will increase.
The invention is not limited to the embodiments shown and described but modifications and variants are possible within the scope of the accompanying claims.
