The lower part of the two-way guide 6 is movably mounted to the slide groove 7 of the guide member A, and they are interconnected through a gear or the like so that the rotation of the take-up drum 3 and the rotation of the cylinder body 5 are synchronized. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

The present invention relates to a manually wound winch capable of aligning and winding wires.

When winding a wire with a hand-winding winch, there is a problem that a turbulent winding phenomenon in which the wire is wound in one or several places on the winding drum is likely to occur.

Also, for example, when a wire is loaded in a state where a load is applied, and the wire falls from the peak portion to the valley portion of the winding wire, the yaiya will loosen for a moment, thereby causing a risk that the load will fall. was there.

The present invention has been made to solve the problems described in the background art, and an object thereof is to provide a hand-wound winch capable of aligning and winding wires.

The hand-winding winch of the present invention is a hand-winding winch that winds the wire around a winding drum while turning the wire winding handle, and is provided with an endless spiral groove adjacent to the front of the winding drum. The base of the bifurcated guide is slidably mounted in the spiral groove, and the bifurcated guide is guided to move parallel to the axial direction of the winding drum. A guide member provided with a slide groove is provided above the cylindrical body, and a lower part of the bifurcated guide is movably mounted in the slide groove of the guide member, and the rotating shaft of the winding drum The gear mounted on the rotating shaft of the cylindrical body is directly meshed with the gear mounted on the rotating shaft of the cylindrical body, or the rotational force of the gear mounted on the rotating shaft of the winding drum is transmitted to the gear mounted on the rotating shaft of the cylindrical body. As the winding de A gear mounted to the rotating shaft of the arm and a wheel mounted on the rotary shaft of the cylindrical body is characterized in that it has connected by chain.

Since the present invention is configured as described above, the following effects can be obtained.
(1) When the take-up drum is rotated, the cylinder is rotated in conjunction with it, and the base of the bifurcated guide is applied with driving force while sliding in the spiral groove of the cylinder, and the slide groove of the guide member Since the inside moves back and forth in parallel to the axial direction of the take-up drum, the wire is always moved in parallel to the axial direction of the take-up drum by attaching the wire to the bifurcated portion of the bifurcated guide and winding the wire. Since it can be rolled up, it is possible to prevent turbulent winding that is biased to only one place.
(2) Wires can be aligned and wound.

For the purpose of providing a hand-wound winch capable of winding wires in an aligned manner, a cylindrical body provided with an endless spiral groove, a bifurcated guide having a base slidably mounted in the spiral groove, and the bifurcated guide are provided. This was realized by a combination with a guide member provided with a slide groove for guiding it so as to move parallel to the axial direction of the winding drum.

An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a hand-winding winch that winds a wire 1 around a winding drum 3 while turning the wire 1 by a hand-wound handle 2, and is adjacent to the front of the winding drum 3, and is an endless spiral groove. The cylinder 5 provided with 4 is rotatably installed.

The base of the bifurcated guide 6 is slidably mounted in the spiral groove 4, and a slide groove 7 is provided for guiding the bifurcated guide 6 so as to move parallel to the axial direction of the winding drum 3. The guide member A is installed above the cylinder 5, and the lower part of the bifurcated guide 6 is movably attached to the slide groove 7 of the guide member A.

Therefore, when the cylindrical body 5 is rotated, the bifurcated guide 6 moves along the spiral groove 4, but its moving direction is regulated by the guide member A, and always moves back and forth in the slide groove 7. It moves in parallel to the axial direction.

In addition, the spiral groove 4 of the cylinder 5 is engraved so that the bifurcated guide 6 can reciprocate the slide groove 7 of the guide member A once when the cylinder 5 rotates once.

The gear 8 mounted on the rotating shaft of the winding drum 3 and the gear 9 mounted on the rotating shaft of the cylindrical body 5 are directly meshed with each other, or the rotational force of the gear 8 mounted on the rotating shaft of the winding drum 3 is the cylindrical body. Although not shown so as to be transmitted to the gear 9 mounted on the rotating shaft 5, the gear 8 mounted on the rotating shaft of the winding drum 3 and the gear 9 mounted on the rotating shaft of the cylindrical body 5 are It is connected.

In winding the wire, first, the wire 1 is attached to the bifurcated guide 6 and the hand-wound handle 2 is turned. In association with this, the cylindrical body 5 rotates, and the bifurcated guide 6 The wire 1 is fed into the take-up drum 3 in an aligned manner while reciprocating in the slide groove 7 of the guide member A in parallel with the axial direction of the take-up drum 3 while sliding on the spiral groove 4.

Although not shown, the bifurcated guide 6 is provided with a member for sandwiching a wire for applying a back tension to the wire 1.

The wire can be used as a means for preventing random winding of a manually wound winch having a multilayer winding structure.
