Background

Unless otherwise indicated in this specification, the description of a unit is not prior art to the claims in this application and is not admitted to be prior art by inclusion in the unit.

Recently, in order to utilize the vehicle interior space, a seat folding function is provided to expand a trunk space or provide a space inside the vehicle for a passenger to conveniently utilize for various purposes.

In addition, in order to provide a large space for camping equipment or leisure and sports equipment of vehicle occupants, a space inside the vehicle is increased by a trunk space and a folding seat, and a Sport Utility Vehicle (SUV) that is superior to a van-type passenger car in terms of space utilization is also preferred in terms of vehicle sales.

Therefore, in order to conveniently fold the 2-row or 3-row seats in the vehicle interior to expand the trunk space, it is necessary to connect the cable extending from the folding unit of the seat and the opening and closing member disposed on the trunk side by the connection device.

However, the distance between the opening and closing member disposed at the trunk side and the 2-row or 3-row seats is long, and the distance between the opening and closing member and the cable extending from the folding unit of the seat varies depending on the kind of vehicle, so that a connection device capable of elastically adjusting the length and conveniently attaching and detaching the cable extending from the seat is required.

In this regard, Korean registered patent publication No. 10-1537975 discloses a separate cable binding structure for a vehicle seat fixing device, and Korean laid-open patent publication No. 10-2016-.

However, the conventional cable connecting device does not disclose a structure for conveniently connecting a cable between a seat of a vehicle 2 or 3 rows and a trunk-side opening and closing member disposed at a remote position.

Detailed Description

The configuration, operation and effect of the cable connecting device for connecting cables according to the preferred embodiment will be described with reference to the accompanying drawings. For reference, two or more components are omitted or schematically shown in the drawings for convenience and clarity, and the size of each component does not reflect the actual size thereof. The same reference numerals are used throughout the specification to designate the same components, and the same components in the respective drawings are not designated by the reference numerals.

Fig. 1 is a state view of a cable connecting device according to an embodiment of the present disclosure.

As shown in fig. 1, the cable connection device 100 includes a second cable 20, a connection member 200, and a length adjustment member 400.

One end of the cable connection device 100 is connected to the folding unit 1 through the first cable 10, and the folding unit 1 is coupled to the seat frame 3 to fold the seat frame 3 or unfold the seat frame 3 to provide a space in which a rider can sit.

The other end of the cable connection device 100 is disposed at the trunk side of the vehicle and connected to each other by the third cable 30 and the opening and closing member 2, and the opening and closing member 2 pulls the connected third cable 30 in the second direction 6 or pushes in the first direction 5 opposite to the second direction 6.

When the worker or passenger who mounts the cable connection device 100 to the vehicle activates the switch member 2 to pull the third cable 30 in the second direction 6, a part of the cable connection device 100 moves in the second direction 6 to pull the first cable 10 in the second direction 6 and further activate the folding unit 1.

In the case of a structure in which the folding unit 1 is operated by driving of the motor in a state in which the seat frame 3 is folded by the activation of the folding unit 1 to connect the luggage space with the upper space of the seat frame 3, a worker or a user re-activates the opening and closing member 2 to unfold the seat frame 3 upward to secure a seating space in front of the seat frame 3.

Accordingly, the worker or the user drives the opening and closing member 2 to move the third cable 30 connected to the first cable 10 in the second direction 6 through the cable connection device 100, and folds or unfolds the seat frame 3 by only the simple operation.

Further, since the connecting member 200 and the length-adjusting member 400 are formed on the third cable 30 side so as to be separated from each other with the second cable 20 interposed therebetween, the length of the cable connecting device 100 itself can be adjusted in the process of connecting the third cable 30 and the length-adjusting member 400 located on the trunk side after the operation of connecting the connecting member 200 to the end of the first cable 10, thereby improving the operational convenience.

Also, the coupling member 200 pressurizes the outside of the coupling member 200 during the coupling with the end of the first rope 10 to restrict the movement thereof with respect to the unit movable in the first or second direction 5, 6 inside, and the unit whose movement is restricted can be conveniently coupled to the coupling protrusion formed with the catching protrusion coupled to the end of the first rope 10.

Fig. 2 is a partial perspective view and a sectional view taken along I-I' of the connection member shown in fig. 1. Fig. 3 is a perspective view illustrating the connection member shown in fig. 1. Fig. 4 is a sectional view of the coupling part shown in fig. 3, taken along II-II'. Fig. 5 is a sectional view of the coupling part shown in fig. 3, taken along III-III'.

As shown in fig. 2 to 6, the connection member 200 includes a connection protrusion 210, a connection unit 220, a first case 230, a second case 240, and a third case 260.

One end of the connection member 200 is assemblably or detachably coupled to the first rope 10 by a connection protrusion 210 coupled to the end of the first rope 10, and the other end is extended in the second direction 6 and is assemblably or detachably coupled to the second rope 20.

The connection member 200 is coupled to the connection protrusion 210 to be slidably moved in the first or second direction 5, 6, and coupled to the protrusion 21 formed at one end of the second rope 20 to be slidably moved in the first or second direction 5, 6.

The connecting protrusion 210 includes a blocking protrusion 212, and a second inclined surface 213 and a blocking surface 214 are formed on the blocking protrusion 212.

The connection protrusion 210 has a catching protrusion 212 formed at an outer side of one end thereof, and the other end thereof is reduced and extended in a stepped shape in the first direction 5 to be coupled to the first rope 10 in a shape of surrounding the first rope 10.

A second inclined surface 213 extending from the outer side of the locking protrusion 212 in the first direction 5 is formed at one end of the outer side surface corresponding to the second direction 6 side of the locking protrusion 212, and the other end of the locking protrusion 212 is recessed toward the back side corresponding to the center of the connection protrusion 210 outside the second inclined surface 213 to form a locking surface 214 facing the first direction 5.

Referring to fig. 4, the first housing 230 includes blocking protrusions 232, 234, 235 and blocking members 236, 237.

One end of the first housing 230 is formed in a cylindrical shape surrounding the connection protrusion 210 and the other end surrounds the connection unit 220 disposed inside and is extended toward the second direction 6 and surrounds the second rope 20, being coupled with the third housing 260 in an assembling or disassembling manner.

A portion of one end of the first housing 230 is inserted into the second housing 240 to be combined with the second housing 240 in an assembling or disassembling manner, and the other end of the first housing 230 is inserted into the third housing 260 to be combined with the third housing 260 in an assembling or disassembling manner.

In a state where the first to third housings 230, 240, 250 are coupled to the corresponding adjacent housings, outer sides of the respective housings are identical to each other, and the outer sides in the coupled state are formed in a flat cylindrical shape, so that a space in the vehicle interior can be saved in a process of being mounted in the vehicle interior, and the cable connecting device 100 can be smoothly slid and moved in a state of being mounted in the vehicle interior, thereby being conveniently mounted.

The blocking protrusion 232 is formed in a ring shape surrounding the outer side surface of one end of the first housing 230 to protrude outward from the outer side surface of one end of the first housing 230, and the second housing 240 is elastically deformed when moving in the second direction 6, and is inserted into the coupling groove 242 formed in the inner side surface of the second housing 240 to be blocked and coupled with the second housing 240.

The catching projections 234 and 235 are formed to protrude from the outer surface of the other end of the first housing 230 toward both sides, and inclined surfaces thereof are formed to extend in the second direction 6 and the back side.

The catching protrusions 234 and 235 are respectively inserted into the inside of the third housing 260 positioned at the second direction 6 side and are respectively inserted into the first and second holes 263 and 265 respectively formed on the locking claws 262 and 264 respectively formed at both sides of the third housing 260, thereby being coupled with the respective locking claws 262 and 264 in an assembling or disassembling manner.

Referring to fig. 5, one end of the blocking member 236 is connected to the inner side surface of the first housing 230 on the second direction 6 side of the outer groove 236a, the outer groove 236a penetrates through the upper outer portion of the first housing 230 to connect the inner space and the outside of the first housing 230, the other end of the blocking member 236 is extended in the first direction 5 in the outer groove 236a, and a part of the other end protrudes upward.

When a corresponding worker or user pushes the other end of the blocking member 236 toward the inner space of the first housing 230, the other end of the blocking member 236 moves toward the inside of the first housing 230, and when the pressure applied to the blocking member 236 is withdrawn, the other end of the blocking member 236 moves to the original position.

One end of the stopper 237 is connected to the inner side surface of the first housing 230 on the second direction 6 side of the outer groove 237a, the outer groove 236a penetrates the outer lower portion of the first housing 230 to connect the inner space and the outside of the first housing 230, and the other end of the stopper 237 extends in the first direction 5 in the outer groove 237a and a part of the other end protrudes downward.

When a worker or a user pushes the other end of the stopper 237 toward the inner space of the first housing 230, the other end of the stopper 237 moves toward the inside of the first housing 230, and when the pressure applied to the stopper 237 is withdrawn, the other end of the stopper 237 moves to the original position.

Referring to fig. 4 and 5, one end of the second housing 240 is coupled to the first cable 10 in a manner of surrounding the outer skin 11 covering the first cable 10, and the other end is extended in the second direction 6 and extended in a cylindrical shape, and is formed with a first groove 241 depressed in the first direction 5.

The connection protrusion 210 is disposed on the inner surface of the first groove 241 corresponding to the second housing 240 and coupled to the first cable 10, and the connection protrusion 210 is movable in the first or second direction 5, 6 in a state of being coupled to the first cable 10, and is moved in the second direction 6 together with the first cable 10 to be separated from the first groove 241.

That is, the outer cover 11 and the second housing 240 coupled to the outer cover 11 can be slidably moved in the first or second direction 5, 6 along the extending direction of the first rope 10.

In addition, a worker or a user moves the second housing 240 and the outer case 11 in the first direction 5 to expose the connection protrusion 210 to the outside while coupling the connection protrusion 210 to the connection unit 220 disposed inside the first housing 230, and moves the connection protrusion 210 in the second direction 6 to be conveniently coupled to the connection unit 220.

The outer surface of the second case 240 surrounding the first rope 10 is obliquely expanded toward the first rope 10 and the second direction 6 to form a curved surface, and the coupling member 200 is mounted in a narrow space of a vehicle and can be conveniently moved to improve the convenience of work.

The third housing 260 includes detents 262, 264.

One end of the third housing 260 is engaged with the first housing 230 in a form of surrounding a portion of the outside of the other end of the first housing 230 to be engaged, and the other end is reduced in the second direction 6 and extended by a predetermined distance.

The other end of the third housing 260 is coupled to the outer skin 22 surrounding the outside of the second rope 20 on the second direction 6 side of the third housing 260 and is slidably movable in the extending direction of the second rope 20.

Referring to fig. 3 and 4, the outer side surface of the third housing 260 surrounding the second cable 20 is extended to be inclined toward the second cable 20 and the first direction 5 to form a curved surface, and in a narrow space of the vehicle, one end of the locking pawl 262 is connected to one side edge of the third housing 260 and the other end is extended toward the first direction 5 in a plate shape having a semicircular section bent to one side, and a quadrangular first hole 263 passing through the locking pawl 262 is formed at the center.

One end of the locking pawl 264 is connected to the other side edge of the third housing 260, and the other end is extended in the first direction 5 in a plate shape having a semicircular cross section bent to the other side, and a quadrangular second hole 265 penetrating the locking pawl 264 is formed at the center.

Therefore, when the third casing 260 is moved in the first direction 5, the engaging protrusions 234 and 235 are inserted into the first and second holes 263 and 265 formed in the locking claws 262 and 264, respectively, and the third casing 260 and the first casing 230 are engaged with each other.

In a state where the catching protrusions 232, 234, 235 formed at the one end and the other end of the first case 230 are coupled to the coupling groove 242, the first hole 263, and the second hole 265, respectively, the outer side surface of the other end of the second case 240, the outer side surface of the first case 230, the outer side surfaces of the locking pawls 262, 264, the outer side surfaces of the catching protrusions 234, 235, and the outer side surface of the one end of the third case 260 are formed such that the surfaces of the outer side surfaces are aligned with each other, so that the outer side surface of the connection member 200 is formed in a smooth cylindrical shape.

The link member 200 is formed in a cylindrical shape having a smooth outer surface, so that the link member 200 is installed in a limited space formed in the vehicle interior and the convenience of work can be improved when sliding and moving during the installation.

Referring to fig. 3 to 5, the connection unit 220 includes the blocking plates 222, 223, 224 and the connector 226.

One end of the connection unit 220 is formed in a cylindrical shape having an inner space opened in the first direction 5, and the other end thereof is extended in the second direction 6 by a predetermined distance and coupled to the protrusion 21 formed at one end of the second rope 20, and a cylindrical insertion groove 225 opened in the first direction 5 and upward is formed.

The insertion groove 225 of the connection unit 220 is formed to be connected to an external space corresponding to an upper portion of the center, and is connected to a cable hole 225a penetrating an upper portion of one end of the connection unit 220, and the connection protrusion 210 and the first cable 10 can be inserted into the connection unit 220 through the insertion groove 225 and the cable hole 225a at an upper portion of the connection unit 220.

The connection unit 220 is coupled to the inner space of the first housing 230 so as to be slidable in the first or second direction 5, 6, and abuts against the other end of each of the stoppers 236, 237 when the other end of each of the stoppers 236, 237 moves into the inner space of the first housing 230, so that the slidable movement in the second direction 6 is restricted.

When the other end of each of the stoppers 236 and 237 is moved to the original position, the connection unit 220 can be slidably moved along the inner side surface of each of the stoppers 236 and 237 in the second direction 6.

The connection protrusion 210 can be easily inserted into the insertion groove 225 in a state where the other ends of the stoppers 236 and 237 move to the inner space of the first housing 230 and the movement of the connection unit 220 to the second direction 6 is restricted.

In the process of inserting the connection protrusion 210 into the insertion slot 225, the blocking protrusion 212 elastically deforms the blocking plates 222, 223, 224 formed on the inner side of the connection unit 220 and then moves by a predetermined distance, and the restored blocking plates 222, 223, 224 closely adhere to the blocking surface 214, so that the movement of the connection protrusion 210 in the first direction 5 is limited.

Accordingly, the corresponding worker or user inserts the connection protrusion 210 into the insertion slot 225 in a state where the movement of the connection unit 220 is restricted by pressing the other end of each of the stoppers 236 and 237, so that the connection protrusion 210 is conveniently and firmly coupled to the connection unit 220.

Referring to fig. 3, one end of the blocking plate 222 is connected to the outer side surface of the connection unit 220 corresponding to the first direction 5 side of the side hole 222a penetrating the upper portion of one side of the connection unit 220 in a rectangular shape, and the other end thereof is extended in a plate shape obliquely toward the inner side of the connection unit 220 and the second direction 6.

One end of the blocking plate 223 is connected to the inner side surface of the connection unit 220 on the first direction 5 side corresponding to the side surface hole 223a penetrating the other upper portion of the connection unit 220 in a rectangular shape, and the other end is extended in a plate shape obliquely toward the back side of the connection unit 220 and the second direction 6.

One end of the stopper plate 224 is connected to the inner side surface of the connection unit 220 on the first direction 5 side corresponding to the lower hole 224a penetrating the lower portion of the connection unit 220 in a rectangular shape, and the other end extends in a plate shape obliquely toward the back side of the connection unit 220 and the second direction 6.

Therefore, referring to fig. 5, when the connection protrusion 210 moves in the second direction 6 and is inserted into the insertion slot 225, the second inclined surface 213 of the blocking protrusion 212 is closely attached to the inclined surface of the blocking plates 222, 223, 224 on the first direction 5 side, and the other ends of the blocking plates 222, 223, 224 elastically move in the second direction 6.

When the second inclined surface 213 of the catching protrusion 212 elastically moves the inclined surface of each of the catching plates 222, 223, and 224 in the first direction 5 side by a predetermined distance, the other end of each of the catching plates 222, 223, and 224 moves to the original position and closely contacts the catching surface 214, and the connection protrusion 210 is fixed to the connection unit 220.

On the other hand, after the corresponding worker or user disengages the second housing 240 from the first housing 230 by the first process of disengaging the connecting protrusion 210 from the connecting unit 220 and slides in the first direction 5, the connecting protrusion 210 is pulled in the first direction 5 to allow the connecting unit 220 to move to the outside of the first housing 230.

In addition, when the connection protrusion 210 is moved upward after moving the connection protrusion 210 in the second direction 6 by a predetermined distance in a state where the connection unit 220 is separated from the first housing 230, the connection protrusion 210 and the first cable 10 are separated from the connection unit 220 through the insertion groove 225 and the cable hole 225 a.

Referring to fig. 3 and 6, the connector 226 includes locking protrusions 227, 228, 229.

One end of the joint 226 is formed to be assembled or disassembled with the other end of the connection unit 220, is formed at the other end of the connection unit 220, and is coupled with the protrusion 21 of the second rope 20.

One end of the joint 226 is formed in a cylindrical shape and the other end is extended in the second direction 6 by a predetermined distance, and a portion of the outer side surface of the other end is extended to be connected to the outer side surface of the connection unit 220.

The engaging protrusion 227 is formed to protrude obliquely to one side at an upper portion of one outer side surface of one end of the joint 226, and is inserted into and fixed to a side surface hole 227a penetrating through the outer side surface of the connection unit 220 on the second direction 6 side.

The locking protrusion 228 is formed to protrude obliquely toward the other side on the upper portion of the other side of the one end of the joint 226, and is inserted into and fixed to a side hole 228a penetrating the other side of the second direction 6 side of the connection unit 220.

The engagement protrusion 229 is formed to protrude downward from the lower portion of the outer surface of one end of the joint 226, and is inserted into and fixed to a side surface hole 229a penetrating the lower outer surface of the connection unit 220 on the second direction 6 side.

Fig. 7 illustrates a perspective view of the length adjustment member of fig. 1. Fig. 8 is an exploded perspective view illustrating a moving unit of the length adjustment member of fig. 1. Fig. 9 is a sectional view taken along IV-IV 'and V-V' of fig. 7.

As shown in fig. 7 to 9, the length adjustment member 400 includes a moving unit 420, a fourth housing 440, and a hook 460.

One end of the length adjustment member 400 is separated from the connection member 200 via the second cable 20, and in this state, is coupled to the other end of the second cable 20 so as to be slidable in the first or second direction 5, 6.

The length-adjusting member 400 is extended by a predetermined distance in the second direction 6 at the other end thereof to be coupled to the third rope 30, and can restrict the sliding movement of the second rope 20 by means of an assemblably or detachably formed hook 460.

The mobile unit 420 includes an assembly unit 422, a catching protrusion 424, and elastic plates 426, 427, 428, 429.

The moving unit 420 has one end coupled to the other end of the second rope 20 and the other end extended in a cylindrical shape in the second direction 6, and is formed to be slidable in the first or second direction 5, 6 inside the length adjustment member 400.

An outer side surface adjacent to one end of the moving unit 420 is formed to be expanded outward to form a catching protrusion 424, and a thread is formed on the outer side surface of the central portion of the moving unit 420 or a ring-shaped protrusion surrounding the outer side surface is formed in a spaced state with a uniform interval therebetween along the extension direction of the moving unit 420.

The other ends of the moving unit 420 are formed with elastic plates 426, 427, 428, 429 in a state of being separated from each other, and the elastic plates 426, 427, 428, 429 are extended in the second direction 6 in a plate shape at the edges of the other ends and have catching protrusions formed at the respective ends.

One ends of the elastic plates 426, 427, 428, 429 are connected to the other end of the mobile unit 420 and surround the inner space of the mobile unit 420, and are formed separately from each other with a predetermined space therebetween, and the other ends of the elastic plates extend in the second direction 6 in a plate shape.

The other ends of the elastic plates 426, 427, 428, 429 protrude outward at a portion thereof to form engaging protrusions, which are formed with inclined surfaces extending in the second direction 6 and the back side of the moving unit 420, and are inserted into a hole in the first direction 5 side of the fourth housing 440, which will be described later, to be elastically deformed and inserted into the fourth housing 440.

One end of the fourth housing 440 is formed in a quadrangular plate shape having a hole formed at the center thereof, and the other end is formed in a plate shape in which both side surfaces of one end are partially extended in the second direction 6 and then extended to be opposite to each other to be coupled to the third rope 30.

Therefore, a right parallelepiped internal space connected to the external spaces corresponding to the upper and lower portions is formed on the inner side of the fourth case 440, and the other end of the moving unit 420 is inserted into the internal space of the fourth case 440 through the hole and is coupled to the fourth case 440 so as to be slidable in the first or second direction 5 or 6.

The upper ends of both side surfaces of one end of the fourth case 440 are respectively formed with the placement grooves 422a and 422b, which are obliquely recessed toward the upper portion of the back side of the fourth case 440, at both side surfaces, and the lower portions of both side surfaces of one end of the fourth case 440 are respectively formed with the coupling grooves 423a and 423b in the form of a rectangular parallelepiped by being partially recessed outward from the bottom surfaces of both sides of the fourth case 440.

Specifically, the inclined surface of the catching protrusion formed at the other end of each of the elastic plates 426, 427, 428, 429 is deformed inward while being in close contact with the inner surface of the fourth housing 440 positioned in the hole when the moving unit 420 is inserted into the fourth housing 440, and the moving unit 420 is moved to the home position when being further moved in the second direction 6.

Moreover, the outer side surface of the moving unit 420 on which the assembly unit 422 is formed can slide and move in the first or second direction 5, 6 after passing through the hole, and when the blocking protrusion 424 reaches one end of the fourth shell 440, the blocking protrusion clings to the fourth shell 440 corresponding to the edge of the hole, so that the moving unit 420 is limited to move in the second direction 6.

On the other hand, when the moving unit 420 moves in the first direction 5 by an external force or vibration of the vehicle body, the engaging protrusions of the elastic plates 426, 427, 428, 429 are brought into close contact with the inner surface of the one end of the fourth case 440 corresponding to the edge of the hole, thereby preventing the moving unit 420 from being separated from the fourth case 440.

Therefore, the catching protrusions of the elastic plates 426, 427, 428, 429 prevent the switch part 2 from being not driven due to the detachment of the moving unit 420 from the fourth housing 440 when the hook 460 is broken or not assembled, and prevent the moving unit 420 from being detached from the fourth housing 440 during the installation of the moving unit 420 to the fourth housing 440 or the coupling of the coupling protrusion 210 to the coupling unit 220, thereby improving the convenience of work.

In a state where the moving unit 420 is inserted into the fourth case 440 through the hole, an inner space is formed between inner surfaces of both sides of the fourth case 440 and the assembly unit 442, and a part of the hook 460 is inserted into the inner space and coupled to the assembly unit 422.

Hook member 460 includes a compression unit 462 and fixing plates 464 and 466.

The pressing unit 462 is divided and extended toward both sides toward the lower portion at the center of the hook 460, and wraps the upper portion and a portion of both side surfaces of the assembly unit 422 formed on the outer side surface of the moving unit 420 to be closely attached to the assembly unit 422.

The inner surface of the pressing unit 462 is formed with a screw or a protrusion and engaged with the screw or the protrusion formed on the assembly unit 422 so that the inner surface of the pressing unit 462 is firmly coupled to the assembly unit 422 while closely contacting the assembly unit 422, and the assembly unit 422 and the pressing unit 462 can be easily separated by moving the hook member 460 upward.

The outer side surface of the pressing unit 462 is formed with a screw or a protrusion to be engaged with a screw or a protrusion formed on the inner side surface of the fourth housing 440 closely attached to the outer side surface of the pressing unit 462, and the pressing unit 462 can be easily separated from the inner side surface of the fourth housing 440 by moving the hook member 460 upward.

The fixing plate 466 is extended downward in a state of being isolated from one side of the pressurizing unit 462, and a portion of the lower end thereof protrudes toward the other side of the pressurizing unit 462 to be inserted into and fixed to the coupling groove 423a in a state of coupling the pressurizing unit 462 and the moving unit 420.

A portion of the outer surface of the lower end of the fixing plate 466 is extended obliquely toward the outer lower portion to form a handle, and a user can pull the handle outward to conveniently separate the fixing plate 466 from the coupling groove 423 a.

The fixing plate 464 extends downward while being isolated from the other side of the pressurizing unit 462, and a portion of the lower end thereof protrudes toward one side of the pressurizing unit 462 to be inserted into and fixed to the coupling groove 423b while the pressurizing unit 462 and the moving unit 420 are coupled.

A portion of the outer surface of the lower end of the fixing plate 464 is extended to be inclined toward the outer lower portion to form a handle, and a user can pull the handle outward to separate the fixing plate 464 from the coupling groove 423 b.

Therefore, when the hook member 460 is coupled to the moving unit 420 and the fourth case 440, the movement of the fixing plates 464 and 466 in the second direction 6 is restricted by the inner surfaces of the coupling grooves 423a and 423b on the first direction 5 side of the fourth case 440, and the movement of the moving unit 420 in the second direction 6 is also restricted.

When the hook member 460 is coupled to the moving unit 420 and the fourth case 440, the surface of the first direction 5 side pressing unit 462 of the hook member 460 is in close contact with the inner surface of the one end of the fourth case 440 corresponding to the hole edge portion of the fourth case 440 in the built-in space, and the movement of the hook member 460 in the first direction 5 is restricted.

On the other hand, if the fixing plates 464 and 466 are separated from the coupling grooves 423a and 423b and then moved upward, they can be inserted into the seating grooves 422a and 422b, and at this time, the hook member 460 is temporarily fixed to the upper portion of one end of the fourth housing 440 to prevent loss, and if the moving unit 420 is moved to adjust the position of the second rope 20, the hook member 460 is rapidly moved downward to fix the position of the moving unit 420.

One end of the spring 470 penetrates the other end of the moving unit 420 and is coupled to the outer skin 22 surrounding the second rope 20 inside the moving unit 420, and the other end passes through the other end of the moving unit 420 and is coupled to the inner side of the other end of the fourth housing 440.

The elastic force of the spring 470 pulls the coupled moving unit 420 in the second direction 6, and when the coupling protrusion 210 and the coupling unit 220 are coupled, automatically pulls the second rope 20 in the second direction 6 to maintain the tension of the coupled first and second ropes 10 and 20.
