Description

The present invention relates to a rope connected to a net or a seat, an endless winch used for a gondola rope, and a rope moving method using the endless winch.

Conventionally, for example, an endless winch used to move a rope connected to a net or a seat is rotatably supported by the winch body and rotated by connecting a drive source (an electric motor or a manual handle). A driving shaft to be driven, a disk-shaped winding drum attached to the driving shaft and having a groove formed along the outer peripheral surface, and a rope taken into and into the groove of the winding drum A pair of guide rollers for guiding the take-out, a moving roller that is attached along the groove on the rope take-out side from the rope take-in side, and is formed by connecting a plurality of rollers; It is comprised from the elastic bodies, such as a spring directly connected with the edge part roller of the both ends side, or indirectly through the connection board attached to the spindle of the said guide roller.

When the rope is moved using the endless winch, first, the drive shaft is rotationally driven using a drive source, and the winding drum is rotated and the rope is moved through the guide roller. Incorporating into one end, using the biasing force of the elastic body connected to the moving roller, the end roller portion sequentially pushes the rope toward the groove while moving to the groove, and then along the groove The rope is wound around the groove while being pressed by the moving roller, and is sequentially taken out from the groove in a state where the end roller is pressed to the groove side by an elastic body connected to the other side of the moving roller, and is passed through the guide roller. Remove from the winch body and move.

Since the moving roller used in the endless winch is composed of a single roller, the amount of movement between the take-in side of the rope groove and the take-out side of the rope from the groove is linked. For this reason, when the pressing movement amount of the moving roller on the intake side is large, the end roller moves greatly to the elastic body side on the take-out side and the urging force by the elastic body does not act strongly. If the pressing force becomes weak and the pressing movement amount of the moving roller on the intake side is small, the movement of the end roller on the take-out side is small, and the pressing force on the groove side by the end roller is too strong. There was a drawback that the rope could not be moved smoothly according to the strength of the tension.

Therefore, a moving roller body in which the moving roller is divided into two at the central portion has been considered. Each of the moving roller bodies is directly connected to the end roller on the rope take-in side and the end roller on the rope take-out side, respectively, or connected to the support shaft of the guide roller via a connecting plate, By pressing the opposite end of each moving roller body on the winch body in the vicinity of the winding drum, the pressure moving toward the groove side by each moving roller body on the rope intake side and rope take-out side Can be performed independently.

As a result, the one moving roller body and the other moving roller body can freely correspond to the tension applied to the rope.
JP 2012-56769 A

Problems to be solved by the invention

However, the above-mentioned conventional endless winch is formed by each moving roller body in which the moving roller is divided into two parts, and is configured to respond independently to the strength of the rope tension. Compared to the end roller on the intake side of the connected rope and the end roller on the rope take-out side, the opposite side is directly fixed to the winch body via the support shaft at a position along the outer peripheral surface of the winding drum. Therefore, at the end of the rope take-in side and the end of the rope take-out side, the elastic means pushes the groove side, but the opposite side is fixed to the winch body, so the winding drum There is a disadvantage that the pressing movement to the groove along the rotation direction of the rope cannot be performed, and fine adjustment to the strength of the tension applied to the rope cannot be performed.

Similarly, in the configuration in which the rope is guided and moved by connecting the end roller of each moving roller body to the support shaft of each guide roller via the connecting plate, the opposite side of the moving roller body is the winch body. Since it is fixed, each moving roller body does not move along the rotation direction of the winding drum, and there is a drawback that it cannot be sufficiently interlocked with the guide roller.

Further, since the opposite side of the moving roller body is fixed, the moving roller body moves by a desired amount along the direction of rotation of the winding drum on the rope taking side of the moving roller body and the fixed portion side is slackened. As a result, the pressing force to the groove side on the end roller side, which is a fixed portion, is insufficient, and there is a defect that the rope is bent or the like depending on the tension applied to the rope.

Further, since the rope is strongly pressed at the fixed portion of the end roller of the moving roller body on the take-out side, there is a disadvantage that the wear of the rope becomes severe.

Therefore, the present invention is an endless system that can move the rope appropriately according to the strength of the rope tension on the rope take-in side and the rope take-out side, and that can smoothly and surely guide and push the rope. It is an object of the present invention to provide a method for moving a rope using the endless winch and the endless winch.

Means for solving the problem

An endless winch as a means for solving the above-mentioned problems is provided, as described in claim 1, with a drive shaft rotatably attached to the winch body and driven to rotate by a drive source, and an outer peripheral surface attached to the drive shaft. A winding drum for moving the rope along the groove formed on the winding drum, and a plurality of drums attached to the winding drum groove in a state of being divided into two along the rope take-out side from the rope take-in side In an endless winch composed of a moving roller body formed by connecting two rollers, a rope to the groove side is directly or indirectly provided at one end of each of the two divided moving rollers. Guiding means for guiding and guiding the rope from the groove side is provided, and the other end side of each moving roller body is pivotally supported on the winch body via elastic means.

The rope moving method using the endless winch as means for solving the above-described problem is that, as described in claim 2, the drive shaft rotatably attached to the winch body is rotated by the drive of the drive source. By driving and rotating the winding drum attached to the drive shaft, the rope is moved along the groove formed on the outer peripheral surface of the winding drum, and the rope is moved along the groove. In the method of moving a rope using an endless winch that moves in and out of the rope while pressing the rope against the groove side with the moving roller body attached in a divided state, the rope of the one moving roller body The guiding means attached directly or indirectly to the intake side end portion guides and moves the rope to the groove side while guiding the rope to the groove side, and the movement of the moving roller body. The side end is pivotally supported on the winch body through an elastic body in the vicinity of the winding drum, so that the incorporated rope is wound and moved along the groove while adjusting the pressure on the groove side, and then the other movement. The opposite end of the roller body is pivotally supported on the winch body through elastic means in the vicinity of the winding drum, and further, the rope is wound and moved to the rope take-out side while adjusting the pressure to the groove side. The rope is taken out and moved from the groove while being guided in a state where the rope is pressed to the groove side by guiding means directly or indirectly attached to the rope take-out side end of the moving roller body.

Effects of the invention

Next, the effects of the endless winch of the present invention and the rope moving method using the endless winch will be described.

First, an endless winch according to claim 1 includes a drive shaft rotatably attached to the winch body, a winding drum attached to the drive shaft and having grooves formed on the outer peripheral surface, and the winding drum. It is attached in a state of being divided into two along the rope take-out side from the rope take-in side to the groove, and is composed of a moving roller body formed by connecting a plurality of rollers.

One end side of each moving roller body is provided with guiding means for guiding the rope to the groove side and the rope from the groove side directly or indirectly. It can be guided and moved while pressing the rope to the groove side of the winding drum via the guide means, and can be guided and moved by pressing the rope toward the groove with the other moving roller body. .

Further, since the other end side of each moving roller body is pivotally supported by the winch body via the elastic means, the elastic force of the elastic means is applied when guided by the one moving roller body. The moving roller body is urged in the rotation direction, assisting the guiding movement while moving the end roller on the rope intake side in the rotation direction of the winding drum, and the rope incorporated in the groove Is wound along the groove while pressing and adjusting the groove side using the synchronized movement of the moving roller body.

In addition, when the other moving roller body is guided and moved, the moving roller body is biased in the direction opposite to the rotating direction by using the elastic force of the elastic means, so that the winding drum rotates. While moving in synchronization with the direction opposite to the direction, the rope moves while pressing the rope along the groove, and guide movement is performed while moving the end roller on the take-out side in a direction opposite to the rotation direction of the winding drum. Assist.

For this reason, the amount of movement of the moving roller body can be adjusted by using the biasing force of the elastic means of the moving roller body according to the strength of the tension applied to the rope on the intake side from the groove or on the take-out side from the groove. It can cope with the tension of the rope.

In addition, since the moving roller is formed of a moving roller body divided into two parts, it differs depending on the elastic means in an independent state on the take-in side to the groove side of the rope and on the take-out side from the groove side. An urging force can be applied, and each can correspond to a difference in tension applied to the rope.

In addition, since the moving roller is formed of the moving roller body divided into two as described above, the length of each moving roller body can be adjusted, and the length of each moving roller body can be adjusted. By doing so, it is possible to further flexibly cope with the tension applied to the rope.

Further, since the one end side of the moving roller body is provided with the guide movement directly or indirectly, the urging force by the elastic means can act in conjunction with the guide movement, and the excessive force on the rope The load can be reduced.

Next, in the method of moving a rope using the endless winch according to claim 2 of the present invention, a drive shaft rotatably attached to the winch body is rotationally driven by driving of a drive source, and the drive shaft is moved to the drive shaft. While the attached winding drum is rotated, the rope is formed on the outer peripheral surface of the winding drum and moved into the groove, and after winding along the groove, the rope is taken out from the groove and moved. .

When the rope is taken into the groove of the winding drum, the rope is taken in and moved by one moving roller body attached in a state of being divided into two along the groove of the winding drum.

That is, while moving to the groove side while guiding to the groove side through the guiding means attached directly or indirectly to the end of the rope moving side of the one moving roller body, on the opposite side of the moving roller. Adjusting the rope to the groove side while moving the moving roller body in synchronization with the rotation direction by utilizing the biasing of the winding drum by the attached elastic means (rotation of the winding drum) Direction and the biasing direction of the moving roller body are the same direction, and the moving roller in the rotating direction while pressing the end roller side of the intake side to the groove side more strongly than the end roller side of the opposite side Move the body) and wind the rope along the groove.

As described above, the rope is caused by the guide movement by the guide means connected to the intake side end of the moving roller body and the pressing movement to the groove side by the biasing by the elastic means on the opposite side of the moving roller body. It is possible to cope with such tension.

Next, the rope incorporated in the groove is moved while the moving roller body is moved in synchronization with the rotation direction by using the biasing force of the elastic means attached to the opposite side of the other moving roller body. Adjusting the pressure on the groove side (By the canceling effect in which the rotation direction of the winding drum and the biasing direction of the moving roller body are opposite directions, the end roller on the opposite side and the end roller on the opposite side are made the same. The moving roller body is moved while pressing the groove side), and the rope is wound along the groove to the take-out side from the groove.

For this reason, the rope wound around the groove by the pressure adjustment by the one moving roller body can be continuously wound along the groove by the pressure adjustment by the other moving roller body.

When the rope is taken out from the groove of the winding drum, the other moving roller body is urged by the elastic means attached to the opposite side, and the end roller of the other moving roller body is strongly pressed to the groove side. In this state, while moving the rope away from the groove, it is guided from the groove side via guiding means attached directly or indirectly to the take-out side end of the moving roller body, and the rope is taken out from the winch body. To do.

As described above, the rope moving method using the endless winch of the present invention can move the rope smoothly by interlocking the guiding movement and the pressing movement of the moving roller body.

In addition, since the guided movement and the pressing movement of the moving roller body are interlocked, the guidance and pressing to the rope are always adjusted, and the wear of the rope is also compared to the case of using a conventional endless winch, There is an advantage that can be remarkably reduced.

Furthermore, because the moving roller is installed in two parts, it can be handled independently on the rope take-in side and the take-out side of the winch body, and it can respond to the strength of the tension freely. It does not require frequent maintenance work as in the past.

As described above, the endless winch and the rope moving method using the endless winch according to the present invention are configured such that each moving roller body is formed by forming the moving roller by a moving roller body divided into two. Can be moved independently of each other, and the tension applied to the rope can be handled independently and the tension applied to the rope on the take-in side and the take-out side can be handled independently.

Further, since the moving roller body is provided with the guiding means and the elastic means on the opposite ends, the moving roller body moves while pressing the moving roller body along the groove while guiding the rope. The rope can be moved, and the rope can be taken in and out while finely adjusting the tension applied to the rope.

The endless winch of the present invention and a rope moving method using the endless winch will be described.

FIG. 11 is a flowchart showing a rope moving method using an endless winch, and FIG. 12 is a flowchart showing a rope moving method using an endless winch.

A first embodiment of an endless winch and a rope moving method using the endless winch according to the present invention will be described with reference to the drawings (FIGS. 1 to 7, 11, and 12).

An endless winch 1 according to the present invention is rotatably supported by a rectangular winch main body 2 and a substantially central portion of the winch main body 2, and is connected to a driving source (not shown including a manual type and an electric type). Thus, the drive shaft 3 that is rotationally driven, the winding drum 4 that is attached to the drive shaft 3 and formed in a disk shape, and is formed in a substantially V shape along the outer peripheral surface of the winding drum 4 The movement of the groove 5 for winding the rope 20 and the movement divided into two parts in the range from the take-in side of the rope 20 into the groove 5 to the take-out side of the rope 20 along the winding direction The roller bodies 6A and 6B and the moving roller bodies 6A and 6B are rotatably supported by support shafts 8A and 8B attached in parallel to the winch body 2 in the vicinity of the take-in side and the take-out side of the rope 20. From a pair of guide rollers 7A and 7B It has been made.

The end rollers 9A and 9Z on the rope 20 take-in side and the rope 20 take-out side end rollers 9A and 9Z, which are one end sides of the moving rollers 6A and 6B, are respectively supported by the support shafts 8A and 8B of the guide rollers 7A and 7B. The connecting plates 10A and 10B are connected to one end side of the connecting plates 10A and 10B formed in an arcuate shape, and springs 11A and 11B as elastic means are connected to the other side (the guide rollers 7A and 7B side) of the connecting plates 10A and 10B. Yes.

As a result, the connecting plates 10A and 10B are pressed in the direction (arrow A and arrow Z) in which the end rollers 9A and 9Z are pressed toward the groove 5 by the springs 11A and 11B (rotating and moving about the support shafts 8A and 8B). When the end rollers 9A and 9Z are energized, the moving roller bodies 6A and 6B connected to the end rollers 9A and 9Z are moved toward the guide rollers 9A and 9Z (arrow B and arrow X), respectively. The action to work.

End rollers 9B and 9Y on the opposite side of the moving rollers 6A and 6B (opposite direction to the guide rollers 7A and 7B) are desired in the vicinity of the winding drum 4 via springs 12A and 12B as elastic means. The winch body 2 is pivotally supported while maintaining a distance.

Thereby, each moving roller body 6A, 6B is biased (arrow C, arrow Y) in the direction of the end roller 9B, 9Y, and always (in a state where the winding drum 4 is not rotating). The moving roller bodies 6A, 6B are biased toward the guide rollers 7A, 7B by the springs 11A, 11B of the connecting plates 10A, 10B and to the end rollers 9B, 9Y by the springs 12A, 12B. It is located in a state of being equalized by the bias.

In this state, when the winding drum 4 is rotated by the rotational drive of the drive shaft 3 (counterclockwise direction (arrow D)), the respective moving roller bodies 6A and 6B in the state equalized with the above are respectively A pulling force synchronized with the direction of rotation acts.

Accordingly, the one moving roller body 6A has a biasing direction by the spring 11A in the reverse direction due to a synergistic effect that the pulling direction (arrow D) in the rotation direction and the biasing direction by the spring 12A (arrow C) are the same direction. Pulling along the rotational direction while acting strongly on (arrow A).

Then, the pressing position of the end roller 9A toward the groove 5 is pressed in a direction away from the guide roller 7A, and the rope 20 is moved strongly pressed against the groove 5 side.

Further, in the other moving roller body 6B, the pulling direction (arrow D) in the rotation direction and the biasing direction (arrow Z) by the spring 11B of the connecting plate 10B are the same direction, and the reverse biasing by the spring 12B ( Acts stronger than arrow Y) and is pulled along the direction of rotation.

Then, the pressing position of the end roller 9Z toward the groove 5 is positioned and pressed on the guide roller 7B side, and the rope 20 is moved strongly pressed against the groove 5 side.

Further, the rotation of the connecting plates 10A and 10B toward the groove 5 changes according to the strength of the tension applied to the rope 20.

That is, when the tension applied to the rope 20 on the take-in side of the rope 20 is strong, the connecting plate 10A is strongly biased in the direction away from the groove 5 (arrow E) around the support shaft 8A due to the strong tension from the rope 20. While rotating, it turns to the groove 5 side.

As a result, the position of the end roller 9A of the moving roller body 6A is on the groove 5 side at a position further away from the guide roller 7A.

In addition, when the tension applied to the rope 20 on the rope 20 take-out side is strong, the connection plate 10B is strongly biased in the direction away from the groove 5 (arrow W) with the strong tension from the rope 20 as a center. While turning to the groove 5 side.

As a result, the position of the end roller 9Z of the moving roller body 6B is on the groove 5 side at a position further away from the guide roller 7B.

Next, when the tension applied to the rope 20 is weak on the rope 20 intake side, since the tension by the rope 20 is weak, the connecting plate 10A rotates around the support shaft 8A toward the groove 5 and is close to the guide roller 7A side. It becomes.

Accordingly, the biasing force of the moving roller body 6A by the spring 11A acts strongly, and the end roller 9A is positioned on the groove 5 side close to the guide roller 7A.

Further, when the tension applied to the rope 20 is weak on the rope 20 take-out side, since the tension by the rope 20 is weak, the connecting plate 10B rotates to the groove 5 side around the support shaft 8B and close to the guide roller 7B side. Become.

Thereby, the biasing force of the moving roller body 6B by the spring 11B acts strongly, and the end roller 9Z is positioned on the groove side close to the guide roller 7B.

As described above, the urging of the connecting plates 10A and 10B by the springs 11A and 11B, the urging by the interlocking springs 12A and 12B interlocked with the urging by the springs 11A and 11B, and the action in the rotation direction of the winding drum 4 And the tension strength applied to the rope 20 to adjust the guide movement when the rope 20 is taken into the groove 5 and when the rope 20 is taken out, and the groove 20 side of the rope 20 is interlocked with the guide movement. The pressing movement to can be adjusted.

As described above, the endless winch 1 according to the first embodiment of the present invention is configured, and the case where the rope 20 connected to the net or the sheet is moved using the endless winch 1 will be described.

First, the drive shaft 3 of the endless winch 1 is rotationally driven using a drive source and the winding drum 4 attached to the drive shaft 3 is rotated, and the rope 20 connected to the net or the seat is connected to the winch body. 2 through the guide roller 7A, and the rope 20 is guided and moved to the groove 5 while pressing the end roller 9A connected to the connecting plate 10A attached to the support shaft 8A of the guide roller 7A toward the groove 5 side. To do.

At this time, the rotational movement of the connecting plate 10A is adjusted according to the tension applied to the rope 20.

That is, when the tension applied to the rope 20 is strong, the rope 20 strongly presses the end roller 9A in the outward direction (direction away from the groove 5 (arrow E)) with a strong tension. 5 is small in rotational movement to the side of the groove 5 away from the guide roller 7A, and is guided and moved while pressing the rope 20 (arrow F). While moving strongly (against the bias of the spring 12A) (arrow B), the moving roller body 6A is pressed toward the groove 5 to move.

Further, when the tension applied to the rope 20 is weak, the tension on the end roller 9A by the rope 20 is weak, so that the rotation of the connecting plate 10A to the groove 5 side is large and the position close to the guide roller 7A side. While guiding and moving the rope 20 toward the groove 5 (arrow F), the interlocking moving roller body 6A is weakly pulled (against the bias of the spring 12A) toward the guide roller 7A (arrow B). The moving roller body 6A moves while being pressed toward the groove 5 side.

Next, the rope 20 guided and moved to the groove 5 of the winding drum 4 includes the urging (arrow A) of the connecting plate 10A by the spring 11A corresponding to the strength of the tension applied to the rope 20, and the winding drum. The moving roller body 6A is moved by a combination of the rotational direction 4 (arrow D) and the biasing force (arrow C) by the spring 12A.

That is, the rotating direction of the winding drum 4 (arrow D) and the biasing direction by the spring 12A (arrow C) have a synergistic effect in the same direction, and the biasing direction by the spring 11A (arrow A) is the opposite direction. For the winding of the moving roller body 6A by a combination of the magnitude of the action of each force (difference in action by the spring 11A due to the tension applied to the rope 20 or change in the tension intensity). The movement amount synchronized with the rotation direction of the drum 4 is finely adjusted.

For this reason, the pressing force to the groove 5 side by the moving roller body 6A is adjusted, and the rope 20 is wound and moved along the groove 5 to the first half rotation portion side according to the strength of the tension.

Next, when the rope 20 moves to the latter half rotation portion of the winding drum 4, the rotation direction (arrow D) of the winding drum 4 acting on the other moving roller body 6B and the winding by the spring 11B. Combination of urging in the rotation direction (arrow Z) of the drum 4 and urging (arrow Y) by the spring 12B (difference in action by the spring 11B due to the tension applied to the rope 20 and change in tension) As a result, the amount of movement of the moving roller body 6B synchronized with the rotation direction of the winding drum 4 is finely adjusted.

For this reason, the pressing force to the groove 5 side by the moving roller body 6A is adjusted, and the rope 20 is wound and moved along the groove 4 side to the second half rotation portion side corresponding to the strength of the tension.

The rope 20 wound and moved along the groove 5 is taken out from the groove 5 in a state where the end roller 9Z portion is pressed toward the groove 5 by the urging force of the moving roller body 6B. It is taken out from the winch body 2 through 7B and moved.

Since the one moving roller body 6A and the other moving roller body 6B are attached to the winch body 2 in an independent state, the tension applied to the take-in rope 20 and the take-out rope 20 The rope 20 can be moved smoothly by individually responding to the strength of the tension.

Further, the end rollers 9B, 9Y on the opposite side of the guide rollers 7A, 7B of the respective moving roller bodies 6A, 6B are connected to the springs 12A, 12B and are urged toward the springs 12A, 12B. The rope 20 can be wound around the groove 5 while pressing the springs 12A and 12B on the side of the end rollers 9B and 9Y while pressing the springs 12A and 12B, and the rope 20 can be smoothly moved.

As described above, the endless winch 1 according to the first embodiment can guide and move the rope 20 with the moving roller bodies 6A and 6B divided into two, with the take-in side and the take-out side of the rope 20 being independent from each other. At the same time, the ropes 20 taken into the grooves 5 are connected to the springs 11A and 11B and the springs 12A. The rope 20 can be moved smoothly while being pressed along the groove 5 by using the urging force by 12B and the action of the winding drum 4 in the rotational direction.

Further, both the rotation about the support shafts 8A and 8B by the connecting plates 10A and 10B urged by the springs 11A and 11B and the urging of the moving roller bodies 6A and 6B urged by the springs 12A and 12B are performed. Using the combination, it is possible to freely cope with the tension applied to the rope 20.

In the first embodiment, the connecting plates 10A and 10B biased by the springs 11A and 11B are rotated around the support shafts 8A and 8B. In the present invention, the connecting plates 10A and 10B are configured as described above. For example, the coupling plate can be freely inserted into the support shafts 10A and 10B through the long holes 21A and 21B, so that the coupling plate can be connected to the coupling plates 10A and 10B according to the strength of the tension of the rope 20 10A and 10B are moved loosely to further finely adjust the positions of the end rollers 9A and 9Z toward the groove 4, and the moving amounts of the moving roller bodies 6A and 6B linked to the connecting plates 10A and 10B are further adjusted. It is also possible to perform fine adjustment.

In the first embodiment, each of the divided moving roller bodies 6A and 6B is formed to have an equal length. In the present invention, the length of each moving roller body 6A and 6B is the same. For example, by forming one moving roller body 6A long and forming the other moving roller body 6B short, the incorporated rope 20 can be pressed and moved appropriately, and more tensioned. It is also possible to respond appropriately to the strengths of these.

Further, in the first embodiment, the end rollers 9A and 9Z of the moving roller bodies 6A and 6B are connected (axially supported) to the connecting plates 10A and 10B. However, in the present invention, the connecting plates 10A and 10B and the moving rollers are connected. The connection with the bodies 6A, 6B is not limited to this. For example, separate rollers 31A, 31B are rotatably supported on the connection plates 10A, 10B, and the rollers 31A, 31B and the moving roller bodies are supported. It is also possible to connect the end rollers 9A and 9Z of 6A and 6B.

Further, in the first embodiment, the springs 12A.12 connected to the end rollers 9B, 9Y of the moving roller bodies 6A, 6B. 12B is pivotally supported on the winch body 2 in the vicinity of the winding drum 4 with a desired interval. However, in the present invention, the position where the springs 12A and 12B are pivotally supported is not limited to this. It is also possible to expand the contact area of each moving roller body 6A, 6B to the groove 5 side by pivotally supporting the springs 12A, 12B at the intersecting positions.

Next, a second embodiment of the endless winch 1 according to the present invention will be described with reference to the drawings (FIGS. 8 to 12).

In particular, differences in configuration from the endless winch 1 of the first embodiment will be described.

In the endless winch 1 according to the second embodiment of the present invention, the end roller 9A, 9B side of the moving roller body 6A, 6B divided into two along the groove 5 of the winding drum 4 is the winding drum 4. Near the end of the end roller 9B. 9Y is pivotally supported in the vicinity of the winding drum 4 via springs 12A and 12B as elastic means.

As a result, a synergistic effect of the action in the rotation direction (arrow D) of the winding drum 4 and the urging force in the same direction (arrow C) by the spring 12A acts on one moving roller body 6A. The moving roller body 6B has a counteracting effect between the action of the rotating direction of the winding drum 4 (arrow D) and the biasing of the spring 12B in the reverse direction (arrow Y).

In the vicinity of the end roller 9A, 9Z side of each of the moving roller bodies 6A, 6B, the connecting plates 10A, 10B, which are rotatable about the support shafts 8A, 8B of the guide rollers 7A, 7B, have one end (guide). The springs 11A and 11B are connected to the rollers 7A and 7B), and the rollers 15A and 15B pivotally supported on the other end (end rollers 9A and 9Z side) are urged toward the groove 5 side.

Accordingly, the connecting plates 10A and 10B are rotated in accordance with the tension applied to the rope 20, and the rollers 15A and 15B are urged in the direction away from the groove 5 (arrow E).

That is, when the tension applied to the rope 20 is strong, the tension of the rope 20 acts strongly on the rollers 15A and 15B, and the connecting plates 10A and 10B are rotated in the direction away from the groove 5, thereby The take-in side 20 is located away from the guide rollers 7A and 7B.

In addition, when the tension applied to the rope 20 is weak, the tension applied to the rollers 15A and 15B acts weakly, and the connecting plate 10A and 10B is rotated in a direction away from the groove 5 by a small amount. The take-in side becomes a position close to the guide rollers 7A and 7B.

Further, the endless winch 1 of the present invention is indirectly connected with the guide movement of the rollers 15A and 15B toward the groove 5 by the rotation of the connecting plates 10A and 10B and the pressing movement of the moving roller bodies 6A and 6B. It is a configuration.

In this way, the guide movement is adjusted using the biasing (arrow A, arrow Z) by the springs 11A, 11B of the connecting plates 10A, 10B, and the rotation direction (arrow D) of the winding drum 4 and the spring 12A. , 12B can be adjusted to synchronize with the urging direction (arrow C, arrow Y) or the pressing movement toward the groove 5 side using the canceling effect.

The endless winch 1 of the present invention is configured as described above. Next, the case where the rope 20 connected to the net or the seat is moved using the endless winch 1 will be described.

First, when the drive shaft 3 is rotationally driven by a drive source and the winding drum 4 is rotated, when the rope 20 is taken in from the one guide roller 7A, the connecting plate 10 is changed according to the strength of the tension applied to the rope 20. While rotating against the urging force (arrow A) of the spring 11A, the rope 20 is guided and moved to the groove 5 side by pressing (arrow F) toward the groove 5 with the roller 15A pivotally supported on the connecting plate 10A.

At this time, if the tension applied to the rope 20 is strong, the rope 20 is placed in the groove 5 at a position away from the guide roller 7A while urging the roller 15A strongly away from the groove 5 against the urging by the spring 11A. Move by induction.

When the tension applied to the rope 20 is weak, the urging force by the spring 11A is stronger than the tension applied to the rope 20, so that the rope 20 is placed in the groove 5 near the guide roller 7A while urging the roller 15A toward the groove 5 side. Move to guide.

Thus, the rotation of the connecting plate 10A is adjusted by the tension applied to the rope 20.

Next, the rope 20 taken into the groove 5 presses the end roller 9A of one moving roller body 6A as a starting point.

At this time, the moving roller body 6A is urged by the spring 12A in the direction of the end roller 9B (arrow C) and pulled in the direction of rotation of the winding drum 4 (arrow D). Due to the synergistic effect that the rotation direction is the same direction, the winding is wound around the first half rotation portion of the winding drum 4 while being pressed and adjusted in the groove 5.

The other moving roller body 6B is biased by the spring 12B in the direction of the end roller 9Y (arrow Y) and pulled in the direction of rotation of the winding drum 4 (arrow D). Due to the canceling effect in which the rotation direction is the reverse direction, the winding is continuously wound around the second half rotation portion of the winding drum 4 while being pressed and adjusted in the groove 5.

Thereafter, the rope 20 rotates the connecting plate 10B according to the strength of the tension applied to the rope 20 on the take-out side, and is pressed at the position of pressing (arrow V) toward the groove 5 by the roller 15B of the connecting plate 10B. Then, it is taken out from the winch body 2 through the guide roller 7AB.

Regarding the strength of the tension of the rope 20 on the take-out side, when the tension is strong, the tension received by the roller 15B due to the biasing of the connecting plate 10B toward the groove 5 is large, and the roller 15B is rotated in a direction away from the groove 5. The rope 20 is moved and guided from the groove 5 at a position away from the guide roller 7B.

Further, when the tension is weak, the urging force of the connecting plate 10B toward the groove 5 is smaller than the tension received by the roller 15B, and the roller 15B is rotated toward the groove 5 so that the groove is close to the guide roller 7B. Take out from 5 and guide.

As described above, the endless winch 1 of the second embodiment is pivotally supported on the support shafts 8A and 8B of the guide rollers 7A and 7B that are guided and moved, and the springs 11A. The connecting plates 10A and 10B urged by 11B and the end roller 9B and 9Y side are moved on the rope 20 by moving independently the moving roller bodies 6A and 6B urged by the springs 12A and 12B. Corresponding to the strength of the tension, the connecting plates 10A and 10B correspond to each other, and the pressing adjustment to the groove 5 of the rope 20 corresponds to each moving roller body 6A and 6B, so that the rope 20 can be moved smoothly.

In addition, the rope 20 taken into the groove 5 of the winding drum 4 surely reaches the take-out side along the groove 5 because of the biasing by the springs 12A, 12B on the other end side of the moving roller bodies 6A, 6B. It can move, and the rope 20 is less worn and does not require frequent maintenance work.

In the second embodiment, the diameters of the guide rollers 7A and 7B and the coupling plates 10A and 10B are not particularly limited, but can be freely determined according to the tension applied to the rope 20 to be used.
