Definitions
- This invention relates to a securing device for elongate members such as cables, wires or the like.
- GB 2210517 discloses a connector for two wires in which the wires are urged together by spring loaded mechanisms so as to secure the wires to each other. Both wires must be in position before either wire is secured to the device. The device is very difficult to load. Furthermore the springs are made from thin tensile material and are prone to rusting and breaking when in use.
- the present invention seeks to provide a securing device for securing an elongate member to another item without these drawbacks.
- a securing device for securing an elongate member to another item, said securing device comprising a body defining a passage operative to receive the elongate member, wherein the securing device comprises a wedge means for urging the elongate member against the part of the body defining the passage so as to frictionally secure the elongate member in the securing device.
- Wires are more easily loaded into the securing devices of the present invention than the devices of the prior art.
- the wedge means is not resiliently biased.
- a securing device for securing an elongate member to another item, said securing device comprising a body defining a passage operative to receive the elongate member, when the securing device comprises non-resiliently biased wedge means for urging the elongate member towards another part of the device and/or another member so as to restrict movement of the elongate member in at least one direction.
- the wedge means is magnetically attracted to the elongate member.
- the wedge means is made from non-corrosive magnetic material or non-corrosive material in which a magnetic field may be induced.
- Means for inducing a magnetic field in the wedge means may be provided.
- the wedge means may be deformable. By using a non resilient wedge means the need for moving parts such as springs is eliminated. Thus the device is much more cost effective to make and is more reliable when in use.
- the elongate member comprises wires, cable, rope or the like and preferably comprises a magnetically attractable material such as metal.
- the present invention has particular application in acting as a joint between two cables or the like such that the cables may be pulled in opposite directions away from the device and act as one cable. It can be seen that each cable can usually be secured in the device without the other being present.
- the wedge means may comprise a non-circular body rotatable about a fixed axis, the body having a variable depth from said axis to the outermost region of the body such that when the elongate member is located in position movement of the elongate member in one direction causes more of the body to move towards the elongate member so as to wedge it against the passageway.
- One such rotatable body may be provided per elongate member.
- one such rotatable body may provide the wedge means for two elongate members. Examples of such structures include oval, pear or S-shapes.
- the wedge means may be provided in a chamber which opens into the passageway.
- This chamber may have a variable depth from the passageway. Movement of a body, preferably a regular shaped body such as a ball or cylinder through the chamber from the larger to the smaller part of the chamber will result in the body urging the elongate member towards the passageway and securing the elongate member in position.
- the wedge means may comprise a body which moves from a first position in which it does not engage the elongate member to a second position in which it engages the elongate member so as to secure the elongate member in position.
- both wedge means may urge their respective elongate members in the same direction or opposite directions.
- the wedge means may urge the two elongate members towards the centre of the device or away from the centre of the device.
- wedge means When two arrangements are used one or both of these wedge means may be attracted by one or more magnets.
- the magnetic field may directly attract the wedge means and/or may attract the wedge means by the magnetic field that extends down the elongate member to the wedge means. Serrations or other grips may be provided on the wedge means.
- Fig. 1 is a perspective view of one securing device in connection with the present invention
- Fig. 2 is a perspective view of a second securing device in accordance with the present invention.
- Fig. 3 is a perspective view of a third securing device in accordance with the present invention.
- Fig. 4 is a perspective view of a further securing device in accordance with the present invention.
- Fig. 5 is a fifth securing device in accordance with the present invention.
- Fig. 6 is a sixth securing device in accordance with the present invention.
- Fig. 7 is a plan view of the securing device of Fig. 6; and Fig. 8 is a seventh securing device in accordance with the present invention.
- a securing device 1 comprises a pre cast zinc housing 2 having apertures (only one of which 3 is shown) on opposite sides thereof for receiving cables 4,5 which pass through the housing 2.
- Two magnetic oval brackets 6,7 are mounted on a central axis 8 so as to allow rotation thereof about the axis 8.
- Each oval bracket 6,7 has a varying depth between the axis 8 and the outermost region of the brackets 6,7.
- Each oval bracket 6,7 engages one of the cables.
- each of the cables 4,5 is magnetically attracted to its bracket 6,7.
- a cable securing means 10 comprises a casing formed from upper and lower parts 11,12 each part having a pair of open ended grooves which can run along the length of these parts. When the two parts 11,12 are bolted together by bolts 13 the two pairs of grooves are in register thus defining a pair of passageways 14,15 operative to receive cables 16,17 and the like.
- the cable securing means 10 further comprises a single magnetic and/or spring loaded oval bracket 18. The principle of operation is similar to that previously described with reference to Fig. 1. Movement of the upper cable 16 to the right as illustrated and/or movement of the lower cable 17 to the left causes the bracket 18 to rotate clockwise such that a larger portion of the bracket 18 urges both cables against the walls defining the passageways 14,15.
- a cable connector 20 comprises a casing formed from upper and lower parts 21,22 each part having a pair of open ended grooves which run along the length of the parts. When the two parts are bolted together by bolts 23 the two pairs of grooves are in register thus defining a pair of passageways 24,25 operative to receive cables and the like.
- a rectangular permanent magnet 26 is provided between the two passageways 24,25.
- Two chambers 27,28 are provided adjacent opposite ends of the magnet 26 inbetween the passageways 24,25. These chambers 27,28 open into the passageways 24,25.
- Each of the chambers 27,28 has a wide part 29,30 towards the end of the casing and a relatively narrow part 31,32 towards the magnet 26.
- a ball bearing 33,34 is provided in each chamber 27,28.
- a metal cable 35 In use one end of a metal cable 35 is placed through the lower passageway.
- the magnetic field of the magnetic passes down the cable 35 and attracts the ball bearing 33 in the chamber 66.
- the ball bearing 33 wedges the cable 35 in a fixed position.
- the cable 35 cannot be removed unless the cable 35 is pulled towards the right of the picture thus releasing the ball bearing 33 into the wide part 30 of the chamber 28.
- the upper securing means acts in the same manner with the upper cable 82 being locked in position as it is pulled towards the right and released if pulled towards the left.
- the cable connector 40 illustrated is similar to that previously described except that the ball bearings of Fig. 4 have been replaced with generally triangular shaped metal bodies 41,42. These bodies 41,42 have a narrow part 43 which resides in the part of the chamber remote from the passageway and a wide part 44 which is adjacent the passageway. Referring to the upper passageway as the cable 45 is pulled through the passageway the magnetic field extends through the cable 45 and attracts the body. The body 42 moves from a first inactive position 42A to a second wedging position 42B which secures the cable in position by urging it towards the passageway wall. The other securing means acts in the same manner. As described with reference to Fig. 3 the upper cable is secured in position by pulling it to the right and the lower cable can be secured by pulling it to the left. Pulling the cables in the opposite directions releases the cable.
- FIG. 5 there is shown a further embodiment of the invention 46 similar to that shown in Fig. 4 except that the chambers are provided on the opposite sides of the passageways .
- the manner of operation is the same as that described with reference to Fig. 4
- a securing device 50 comprises an upper body portion 51 and a base 52 which is securable to the upper body portion 51 by way of connecting screws 53,54.
- Two pairs of grooves are provided in both the upper body portion 51 and base 52 such that when the two parts 51,52 are secured together they define two parallel channels 55,56 for receiving elongate members 57 such as wires, cables, rope and the like.
- a part of each groove in the upper body portion 51 opens into an enlarged chamber 58A, 58B.
- the depth of the chambers 58A, 58B is not constant such that the left hand side of the first chamber 58A as illustrated is deeper than the right hand side of that chamber and vice-versa with the other chamber 58B.
- a cylindrical wedge 59A, 59B is provided in each chamber 58A, 58B.
- the wedge pieces are made from non-corrosive magnetic material.
- the dimensions of the wedge pieces 59A, 59B are such that they may move freely in the enlarged part of their respective chambers, but when they move into the smaller parts of the chamber they will wedge in position any wire provided in the part of the groove adjacent the chamber.
- a first metal wire is inserted into the first channel of the device in the direction of Arrow A.
- the magnetic wedge piece will engage the metal wire and move towards the enlarged part of the chamber. Once a sufficient length of wire has been passed past the chamber the wire is then pulled into a direction opposite to Arrow A.
- the magnetic wedge piece engages the wire and is captured between the roof of the chamber and the wire thus urging the wire towards the base of the channel and wedging the wire in position. Further movement of the wire in a direction opposite to Arrow A is not possible.
- the second wire is placed into the left hand side of the second channel by pushing it in the direction of Arrow B. Once captured by the wedge piece the wire cannot be moved back out of the left hand side of the channel as illustrated.
- the device therefore connects two pieces of wire together such that when tension is applied to the cable such that the cables pull the wedge pieces into the small parts of the channel the two cable pieces act as one.
- These securing devices are particularly useful in connecting relatively thin wires together such as those used in vineyards for connecting vines to supports.
- Fig. 8 is a modification of the device of Figs. 6 and 7 in which the device 60 has a channel which is large enough to receive two cables.
- the device 60 operates in a similar mannner to that previously described. Movement of both cables 61,62 in direction C is restrained by the wedge piece.
- the casings of all of the embodiments of the invention preferably comprise metal, such as a zinc alloy.
