Description
APPARATUS FOR ENABLING AN ELONGATE MEMBER TO PASS
IN A SEALED MANNER THROUGH AN APERTURE
This invention relates to apparatus for enabling an elongate member to pass in a sealed manner through an aperture. More especially, this invention relates to apparatus for enabling at least one elongate member to pass in a sealed manner through at least one aperture in an object.
The passage of elongate members such for example as cables and wires often cannot satisfactorily be achieved when the cables and wires are to pass in a sealed manner through objects such for example as decks and bulkheads on boats and ships. Water tends to leak through the decks and bulkheads and corrosion of fittings can then take place. With electrical equipment, in addition to the problem of corrosion, there is the further problem of possible short circuits caused by the ingress of the water.
It is an aim of the present invention to obviate or reduce the above mentioned problem, whilst at the same time enabling elongate members such for example as the cables and the wires to easily be removed from their aperture or apertures in the object such for example as the deck or the bulkhead.
Accordingly, this invention provides apparatus for enabling at least one elongate member to pass in a sealed manner through at least one aperture in an object, which apparatus comprises a first part for securing to the object, and a second part for securing to the elongate member, the first part having at least one aperture which aligns wlth the aperture in the object when the first part is secured to the object, and the second part having an insert portion which fits over the elongate member, and sealing means for effecting a seal between the insert portion and the elongate member, and the apparatus being such that the second part locks and unlocks to the first part.
The elongate member may be a cable, a wire, a pipe or a rod. The object may be a deck, a bulkhead or part of an enclosure. With the apparatus of the invention, the elongate member is able to pass in a sealed manner through the object, with the locking and unlocking facility enabling the elongate member quickly to be withdrawn from the aperture in the object as and when required. Thus for use on boats and ships, equipment mounted above deck can rapidly be removed. For example, cables can be recovered without having to remove connectors. Furthermore, with the sealing facility provided by the apparatus of the present invention, there is no danger of water seeping through the apparatus and causing corrosion or electrical short circuits.
Preferably, the apparatus is one in which the second part locks to the first part by'an axial movement, and in which the second part unlocks from the first part by a twisting and pulling action.
Usually, it will be the insert portion of the second part that will lock and unlock to the first part.
The insert portion may have at least one protuberance which is received in a hole in the first part when the first and the second parts are axially moved together.
If desired, the reverse arrangement may be employed in which the protuberance is in the first part and in which the hole is in the insert portion.
The first part may comprise an externally threaded cylindrical portion for passing through the aperture in the object, and a locking nut. Alternatively, the first part may comprise a mounting flange for being mounted on a surface of the object surrounding the aperture in the object.
Preferably, the apparatus includes a sealing gasket for use with the mounting flange.
The sealing means may comprise a sealing ring for sliding over the elongate member, and a screw threaded abutment member for screwing into the insert portion and compressing the sealing ring to effect a seal.
The insert portion may have a sealing member for effecting a seal between the insert portion and the first part. The sealing member may be a sealing ring.
Preferably, the second part includes a strain relief sleeve. The strain relief sleeve is especially useful when the elongate member is a flexible elongate member such for example as a cable.
The apparatus of the invention may be such that there is only one aperture in the first part, the aperture in the first part being for receiving one or more of the elongate members.
Alternatively, the apparatus may be such that there are two or more apertures in the first part, there being a separate aperture for each elongate member. Thus, for example, the apparatus may have three apertures in the first part for receiving three separate elongate members. Various combinations of aperture or apertures in the object, the first part and the second part may be employed to suit manufacturing and/or installation convenience.
The apparatus may include a bung for closing the aperture in the object when the second part is not locked in the first part.
The bung may have a sealing ring for sealing to the first part, and a handle for enabling the bung to be pulled from the first part.
Preferably, the apparatus includes indicator means for indicating when the first and the second parts are in locking engagement with each other.
The indicator means may comprise a pair of marks, one on the first part and one on the second part, and the pair of marks being such that when they are aligned the first and the second parts are in locking engagement with each other. The marks may be arrowheads , straight lines or dots.
Embodiments of the invention will now be described solely by way of example and with reference to the accompanying drawings in which:
Figure 1 illustrates how apparatus of the invention is used;
Figure 2 shows first apparatus of the invention;
Figure 3 shows second apparatus of the invention;
Figure 4 shows third apparatus of the invention; and
Figure 5 shows fourth apparatus of the invention.
Referring to Figure 1, there is shown apparatus 2 for enabling cables 4,6,8,10 to pass in a sealed manner through an aperture 12 in an object in the form of a deck 14 on a boat.
The cables 4,6,8,10 each have a plug 16 for fitting into a socket. Thus the cable 4 has a plug 16 for plugging into a radio 18, the cable 6 has a plug 16 for plugging into radar equipment 20, the cable 8 has a plug 16 for plugging into navigation equipment 22, and the cable 10 has a plug 16 for plugging into a socket 22 which provides power for lights.
As shown in Figure 1, the cables'4,6,8,10 pass through the deck 14 and up a mast 24 where they connect to mast head electrical equipment such for example as a light 26 and a scanning aerial 28.
The following Figures 2, 3, 4 and 5 show different types of apparatus 2 for enabling one or more cables such for example as the cables 4,6,8,10 to pass in a sealed manner through one or more apertures such as the aperture 12 in an object such for example as the deck 14. The deck 14 could equally well be a bulkhead, the surface of a container or any other desired and suitable object.
Referring now specifically to Figure 2, there is shown the apparatus 2 which comprises a first part 30 for securing to the deck 14, and a second part 32 for securing to an elongate member in the form of the cable 4.
The first part 30 has an aperture 34 which aligns with the aperture 12 in the deck 14 when the first part 30 is secured to the deck 14.
The second part 32 has an insert portion 36 which fits over the cable 4 as shown. The second part 32 also has sealing means 38 for effecting a seal between the insert portion 36 and the cable 4.
The apparatus is such that the second part 32 locks and unlocks to the first part 30. The locking is effected by axially pushing the insert portion 36 of the second part 32 into the aperture 34 in the first part 30, when a pair of protuberances 42 on the insert portion 36 engage in complementary holes 40 in the first part 30.
The unlocking is effected by rotating the second part 32 relative to the first part 30 to cause the protuberances 42 to come out of their holes 40, whereupon the second part 32 can be pulled axially out of the first part 30.
As the insert portion 36 is pushed into the aperture 34, the pair of protuberances 40 are guided by a pair of guide slots 43 in the wall of the first part 30 defining the aperture 34. The insert portion 36 is provided with slits 45 on either side of each protuberance 42, the slits 45 enabling the protuberances 42 to flex in and out to engage and disengage easily but firmly and positively in the holes 40.
As can be seen from Figure 2, the first part 30 comprises an externally threaded cylindrical portion 44 for passing through the aperture 12 in the deck 14. The first part 30 also comprises a locking nut 46 which is able to screw up the threaded portion 44 and lock the first part 30 in position with the deck 14 being trapped between the locking nut 46 and a flange 48. As will be appreciated, the locking nut 46 will be underneath the deck 14 and the flange 48 will be on top of the deck 14.
The sealing means 38 comprises a sealing ring 50 which is of a substantial size as shown and which slides over the cable 4, also as shown. The sealing ring 50 can be slid up the cable 4 and into a recess (not visible in Figure 2) in the insert portion 36. This recess is internally screw threaded and a screw threaded abutment member 52 is able to screw into the recess in the insert portion 36. The abutment member 52 has a screw threaded portion 54 and a serrated portion 56 for providing a good finger and thumb grip for enabling the abutment member 52 to be tightly screwed into the insert portion 36. As the abutment member 52 is screwed into the insert portion 36, it compresses the sealing ring 50 which then presses on both the cable 4 and on the insert portion 36 to effect a seal between the cable 4 and the insert portion 36.
The insert portion 36 has a sealing member in the form of a sealing ring 58 which is located around the outside of the insert portion 36 as shown. This sealing ring 58 forms an 0ring seal which seals against the inside of the portion 44 when the insert portion 36 is pushed into the aperture 34.
The insert portion 36 is provided with a flange 60 which sits on a central portion 62 surrounded by the flange 48.
The first part 32 includes a strain relief sleeve 64 which extends from the flange 60 and which goes over the cable 4 as shown.
The apparatus 2 includes indicator means for indicating when the first and the second parts 30,32 are in locking engagement with each other. The indicator means comprises an arrowhead 66 on the flange 48 and a recessed portion 68 on the flange 60, the flange 60 also having a marking 70 for aligning with the arrowhead 66 when the first and the second parts 30,32 are to be in their locking position.
The apparatus 2 further comprises a bung 72 for closing the aperture 12 in the deck 14 when the second part 32 is not locked in the first part 30 and when the second part 32 is removed from the first part 30. As can be seen from Figure 1, the bung 72 has a sealing ring 74 which acts the same as the sealing ring 58 when an insert portion 78 of the bung 72 is pushed through the aperture 34 in the first part 30. The insert portion 78 is provided with a pair of protuberances 80 which are each flanked by slits 81 and which act in the same manner as the protuberances 42. Thus, by rotating the bung 72, the bung 72 can be locked in the aperture 34.
The bung 72 is provided with a handle 82 for enabling the bung 72 to be rotated between its locking and its non-locking positions. The handle 82 is also effective to help the bung 72 to be pulled out of the aperture 34.
The bung 72 has a flange 84 which acts similarly 'to the flange 60 and which is similarly provided with a recessed portion 86 which acts like the recessed portion 68, and a marking 88 which acts like the marking 70.
The bung 72 is provided with a hole 90 in the handle 82 so that the bung 72 can be located on a hook or a spike when it is not in use.
Referring now to Figure 3, there is shown second apparatus 2 which is like the apparatus 2 shown in Figure 2, except that the second part 32 has three strain relief sleeves 64, each for receiving a separate cable, although only one cable 4 is shown for simplicity of illustration. Because the apparatus 2 shown in Figure 3 is able to receive three cables, each having their own aperture in the second part 32, it will be seen that the first part 30 is of larger diameter so that the aperture 34 is able to accommodate the insert portion 36.
Referring now to Figure 4, there is shown apparatus 2 which is similar to the apparatus 2 shown in Figure 3 except that the first part 30 comprises a mounting flange 92 which is provided with holes 94 in ears 96. The holes 94 are for receiving fixing screws 98. The fixing screws 98 pass through holes 100 in a sealing gasket 102 and then the fixing screws 98 screw into holes 104 in the deck 14. The sealing gasket 102 ensures a good water-tight seal between the mounting flange 92 and the upper surface of the deck 14.
Referring now to Figure 5, there is shown apparatus 2 which is like the apparatus 2 shqwn in Figure 4 except that the mounting flange 92 has three separate apertures 34, one for each cable 4,6,8. Similarly, the sealing gasket 102 has three separate apertures 106 instead of the single aperture 106 shown in Figure 4. Also similarly, the deck 14 has three separate apertures 12 instead of the single aperture 12 shown in Figure 4.
The various types of the apparatus 2 enable cables such for example as the cables 4,6,8,10 to pass through the deck 14 without water such for example as rain water or sea water also passing through the aperture or apertures 12 in the deck 14.
The plugs 16 and their sockets are thus not exposed to the adverse effects of water. The apparatus 2 operates with a minimum of joints which thus gives good reliability. The plugs 16 or sockets if desired can be recovered through the deck 14 without the wiring, it only being necessary to separate the plugs and the sockets and the first and the second parts 30,32. This easy removal of the cables enables equipment to be maintained more easily and therefore more frequently. Also, as can be seen from the drawings, the apparatus 2 is compact, of an attractive appearance and it presents a relatively low profile on the deck 14.
The apparatus 2 can be made in any desired materials
Where metals are employed, the metals will usually be corrosion resistant so that a presently preferred metal is stainless steel. Plastics materials may also be employed and a presently preferred plastics material is a: nylon plastics material which is produced to be resistant to the effects of ultra-violet light.
It is to be appreciated that the embodiments of the invention described above with reference to the accompanying drawings have been given by way of example only and that modifications may be effected. Thus, for example, the apparatus 2 can be used with two or more than three cables.
Alternatively, the cables can be replaced by wires, pipes, rods or any other desired and appropriate elongate members.
Further, the deck 14 may be a bulkhead, a part of a container or any desired and appropriate object. Also, the holes 40 may be recesses 40 as shown in Figures 4 and 5.
