Such a device is applicable to remote threading operations, such as threading a boat's mooring line through a tie ring mounted on a buoy or at a fixed location on the shore, and various other similar threading operations. In addition to this threading operation, it is also possible to hold or attach the wire from a distance by holding or fastening the free end of the threaded wire. Other possible applications include retrieving a person or object by wrapping a wire around the person or object and passing the wire through a ring built into the person or object to form a ring around it.

U.S. Pat. No. 2,540,868 (Ehrhart) discloses an intermediate wire suspension system for transporting moving loads, particularly for the wheel transport of logs. The device includes a biased rotor having a slot through which a log suspension element passes. However, Ehrhart's device is configured for suspension operations from elevated structures by means of hooks 12 to support log transport cables 1, and thus this device is completely unsuitable for the threading operations to which the present invention relates. It is.

The present invention provides a wire threading device having the following configuration. That is, a rotor portion consisting of a main body portion, at least one rotor member rotatably attached to the main body portion, a portion of which protrudes from the main body portion, and has a recessed portion on the outer periphery; a threading member, the threading member having an elongated threading portion operative to act on the rotor member and extending to one side of the rotor member in the general plane of the rotor member to engage an annular, endless, or apertured threading element; The wire passing member and rotor member are
When a portion of said element is received in a recess in a rotor member during use, an arcuate mutual engagement causes the rotor member to rotate relative to the threading member, thereby causing said threading member to penetrate said threading element. and means for biasing the rotor member during use to a position where the recess is substantially aligned with a spatial area created between the wire threading portion of the wire threading member and the opposing portion of the body portion. This is a wire threading device characterized by:

In some constructions of the invention, the wire threading member has a wire attachment portion that typically extends to the opposite side of the rotor member wire threading portion and passes through the opening in the element. or other elongated wire threading member with a wire or element connected to the wire threading section.

In other constructions according to the invention, the front threading portion may be provided with means for attaching a wire or other flexible elongated member to it. In such constructions, the elements may be provided together midway along the length of the wire or other member, which wire or other member is wrapped around a person or object and then threaded through the wire. A member passes through the element, allowing a ring to be formed around a person or object from a remote location.

Said rotor portion consists of two separate rotor members each having a circumferential recess, the recesses of the rotor members being arranged one-on-one with respect to each other, wherein the wire threading member and the body portion extend between the rotor members. There is. In another possible embodiment, the rotor portion comprises a single rotor member, and the threading member and body portion are configured to enclose respective peripheral portions of the rotor member.

The interengaging means includes at least one arcuate recess in the or each rotor member and at least one correspondence provided in the wire threading member to engage the or each recess in the rotor member. or the opposite configuration.

The rotor portion includes at least one arcuate recess in the or each rotor member and at least one corresponding arcuate projection provided in the body portion to engage the or each recess in the rotor member. or vice versa. The arcuate recess in the rotor portion may be placed eccentrically with respect to the rotor portion to increase leverage while the element passes through the device. This eccentric structure also changes the useful clearance between the body portion and the threading portion.

In other embodiments, the rotor portion is arranged such that leverage is increased during passage of the element through the device compared to an arrangement where the rotor portion rotates about a symmetrically disposed axis. It is attached to the body part for relative rotational movement by an axis that is eccentrically disposed with respect to the part.

The rotor portion is constituted by a disc member having the recessed portion formed on its outer periphery, or such a disc member as a rotor member.

Said biasing means comprises an elongated resilient member connected between the body part and the rotor part to rotate the rotor part in one direction towards said position.
Interengagable stop means are provided on the body portion and the rotor portion to lock the rotor portion in said position when the rotor portion is returned to said position under the action of said biasing means. The other biasing means comprises an elongated resilient member, one end of which is removably mounted on the tip or shank portion of the body portion for holding the rotor portion in one or the other position. A movable pin selectively engages the tip or shank portion.

The threading device may take the form of an end fitting attached to one end of an elongated handle, such as a wooden or metal rod or rod.

The various parts of the threading device according to the invention may be molded from sheet metal or from plastic material.

Referring to FIGS. 1-4 and 8, the threading device 10 of the present invention is shown in the form of an unended attachment that attaches to one end of an elongated handle, such as a wooden rod. The device consists of a hollow body part 11 with a tubular shank for attachment to one end of a wooden rod. Wooden part 1
1 has a recess 12 formed in its upper surface, which recess is connected to the rotor part 13 of the device described below.
Store the shaft part of.

The rotor portion 13 of the device consists of a pair of spaced apart rotor members, discs 14, having integrally formed boss portions 15, which project from and are in contact with the periphery of the discs. The boss portions are arranged eccentrically in relation to each other, and the boss portions are fixed to each other to form a hub of the rotor portion 13. This hub is housed in the recess 12 of the body part 11. Each disk 1 of the rotor part
4 is formed with an outer peripheral recess 16, and the recesses of the two discs 14 are arranged in a line with each other. Further, each disc 14 has an arcuate groove 17 and a second
an inner arcuate groove 17A is formed, said arcuate groove 17 being spaced inward and concentric with the outer periphery of the disk extending between the opposite side walls of the slot 16; 17A is concentric with the rotor hub and is therefore eccentric in relation to the circumference of the disk and to the outer arcuate groove 17.
The grooves 17 and 17A of the disc 14 are formed on surfaces facing each other. Opposing surfaces of the body portion 11 are formed with protruding ridges 9 which cause the rotor portion 13 to rest on the body portion 11 during rotation of the rotor portion 13 relative to the body portion.
It matches and engages with the groove 17A of the disc 14 so as to position it.

Furthermore, the device comprises a wire threading member 18;
The threading member has a small hole 19 or other attachment means for attaching the rope at one end thereof and an upwardly directed threading portion 20 at the other end. This threading portion 20 extends toward its end progressively away from the main body portion 11 of the device to facilitate engagement of the threading member within a ring or other member. A rope attached to the threading member 18 is then passed through or around this ring. A pair of arcuate protrusions 21
are provided on opposite sides of the central portion of the wire threading member 18, and are respectively engaged in the grooves 17 of the pair of disc members 14. In this manner, the threading member 18 is positioned relative to the rotor portion 13 during rotation of the rotor member relative to the threading member.

The elastic cord 22 is inserted into the inlet slot 23 formed between the wire passing portion 20 of the wire passing member 18 and the opposing portion of the main body portion 11 and the recess 1 of the disc 14.
6 in line so that in use a ring or other member that is engaged in use within the entry slot 23 may be engaged within the recess 16 during the threading operation. can. The cord 22 is attached to one end within the hollow tip of the body portion 11 by a movable pin 25. The cord then extends into the recess 12 formed in the body part and is partially wrapped around the hub 15 of the rotor part 13. The cord is disposed within an edge 15A, which extends partially around the hub 15. The other end of the cord is attached to a fixture 24 provided on the rotor section 13 at the end of the edge 15A, and is adapted to rotate the rotor section clockwise, as seen in FIGS. 1 and 2. The first
Recess 16 in the rotor part as illustrated in the figure.
are aligned with the inlet passageway 23. An arcuate abutment surface 30 projects on the side of the body part 11 and ensures the positioning of the rotor part in this position.

In operation, the wire threading device 10, which is fixed to the end of a wooden rod or pole, can be straddled over a ring or ladder tread provided on the wall of a wharf, or a double stagone ( stag
-horn) Position it by passing it through the T-shaped rod of the stake,
The wire to be attached to the small hole 19 of the wire threading member can be easily handled from a distance so that the wire is threaded through the small hole 19 of the wire threading member. The threading device is then moved rearwardly to engage the ring or ladder tread within the entry passage 23 between the threading member and the body portion 11 of the device. When the wire threading device is moved further rearward, at this time, the recess 1 is held in line with the inside of the inlet passage 23 by the action of the elastic cord 22.
In 6 a ring or treadle is engaged. When the device is further moved rearward, the rotor portion 13 is rotated counterclockwise against the action of the elastic cord 22.
By rotating it to the position illustrated, the ring or treadle passes through the threading device;
The wire threading operation is completed by moving onto the rope or other wire attached to the small hole 19. By holding or securing the free end of the threaded rope or line, remote grasping or attachment operations are possible.

As can be seen, the eccentric mounting of the rotor on the body portion increases leverage during passage of the ring or treadle member through the body of the device.
This is because the eccentric mounting structure acts to rotate the rotor member at a position farther from the axis of the hub. During such passage, the distance between the wire threading member 18 and the main body portion 11 changes. A device such as that shown in FIG. 1 is particularly desirable for threading a wire through a ring provided on a buoy, in which case a rearward pull-back threading operation is preferred. However, in other applications where the ring or treadle member is rigidly mounted, for example mountain climbing applications, it is advantageous to carry out a threading operation in the forward direction. In such a case, the wire passing member 18
is assembled in the opposite direction to that shown in FIG. 1 so that the threading portion 20 is adjacent to the distal end portion of the main body portion 11, and the elastic cord 22 is attached to the shank portion of the main body portion 11 with a movable pin 25. A fixture 24A provided on the rotor portion 13 and connected by
As a result, the rotor member disc 14 is eccentrically rotated in the counterclockwise direction by the cord 22. The second arcuate pressing surface 30A is provided to act as a locking end of the rotor portion.

As will be appreciated, although in the embodiment described above an arcuate protrusion or ridge is provided on the body portion 11 and a grooved wire threading member 18 is provided in the disc 14 of the rotor portion. , in other embodiments, the main body portion 11 and the wire threading member 18
It is also possible to provide a groove on the disc member 14 of the rotor part 13 and to form a cooperating arcuate projection on the disc member 14 of the rotor part 13.

FIG. 5 shows that instead of providing an arcuate projection on the main body portion that engages the groove 17A provided in the disc member 14 as in the embodiment of FIG. 1, the center of the eccentric hub 15 of the rotor portion is Similar to that shown in FIG. 1, except that rotor portion 13 is positioned relative to body portion 11 by a shaft 31 extending therethrough and received in an opening in body portion 32. A second specific example of the wire threading device will be shown.

6 and 7 show a third specific example, in that the hub 33 is arranged concentrically with respect to the outer periphery of a disc 34, which is a rotor member, and each disc 34 is A single arc-shaped groove 35 is provided concentrically and close to the outer periphery of the disc, and an arc-shaped ridge or protrusion with the same curvature engages with the groove 35 of the rotor disc. In that it is provided on both the wire passing member and the main body portion 36 so as to match,
This is different from the specific example shown in FIG. Therefore, although this concentric mounting arrangement of the rotor portion does not provide the increased leverage of an eccentric mounting arrangement, such increased leverage may not be necessary in some applications.

FIG. 9 shows yet another embodiment, which is particularly suitable for retrieving a person or object from a remote location by forming a line ring around the person or object. The construction is generally similar to that shown in FIG. 1, except that the threading device 40 and body portion 41 extend to only one side of the rotor member 13. The rotor section eccentric cord would function in a similar manner to that shown in FIG. 3, but this eccentric cord would be attached to one end of the short body section 41. The elastic clip 42 is attached to the threading portion 43 of the threading device 40;
One end of a rope or other wire 44 is connected to the wire thread. A ring 45 is installed in the rope or wire at an intermediate longitudinal position. The threading device of FIG. 9 provided at the end of the rod or pole is wound around the person or object together with the rope connected thereto, and then the threading device 40 is passed through the ring 45 and wrapped around the person or object. By forming a loop of rope and facilitating its recovery, a person or an object can be recovered, for example from the sea.
A variety of different means can be used to attach the end of the rope 44 to the threading device 40, one example being an elastic piece with a ball at the end and attached to the rope. This elastic piece is fixed in the recess of the wire threading portion 43 via a ball and is attached around the wire threading device. 10 to 12 show a similar rotor section 13 consisting of two similar rotor members, discs 49, as shown in FIG. 11; A device having a short body portion 41 is illustrated. As can be seen, the movement of the rotor portion 13 is caused by the arcuate recess 5 of the body portion 41.
1 by the peg 50 of the disc element 49 which engages within the disc element 49 . This wire threading device main body 48 has a wire threading portion 52 that is shorter than that of the embodiment of FIG.
