  Generally, in order to connect a remote control device to a damper provided in an air conditioning duct, it is necessary to pass the remote control device through a narrow place. For example, in a remote control device including a pulley as described in Patent Document 1, a remote control device including a pulley is inserted from an opening for attaching an air conditioning control panel, and the remote control device is interposed between various structures. It is necessary to guide to the installation position of the damper finally installed in the air-conditioning duct while creating a gap. For this reason, there exists a problem that the magnitude | size of a pulley tends to obstruct such an operation | work and workability | operativity is bad.

  Such a problem is that a pulley is attached in advance to a damper shaft provided in the air conditioning duct, only the cable is inserted from the opening for attaching the air conditioning control panel, and the inserted cable is inserted into the gap between various structures. If it is moved to the position of the pulley while twisting, it will be solved. However, in this case, since the distal end portion of the cable having flexibility hangs down due to gravity, it is imagined that it is not easy to pass the distal end of such a cable through a narrow space.

  The present invention has been made in view of these points, and it is an object of the present invention to improve the workability of the remote control device mounting work, particularly the workability of working the cables through the gaps between various structures. And

  The present invention is provided respectively at a pair of cables, an outer cable that holds the pair of cables adjacent to each other, and a pair of cables that extend from one end of the outer cable. The connecting member held by a pair of cable holding portions respectively provided at two ends of the formed guide groove and the pair of cables extending from the outer cable are positioned at the ends. The outer cable is held so as to be relatively slidable between a first position and a second position where the pair of cables extending from the outer cable are exposed by a length wound around the guide groove of the pulley. And an elongated shaped holder.

  According to the present invention, when guiding a pair of cables as a single cable with respect to a pulley attached in advance to the operated portion side, the tip of the cable held by the outer cable can be held by the holder, and In this case, since the outer cable can be positioned at the first position to prevent the cable tip from being unexpectedly popped out, the flexible cable tip can be prevented from hanging down due to gravity. The workability of passing the cable through the gaps between the various structures can be improved.

  An embodiment will be described with reference to the drawings.

  The remote operation device 11 according to the present embodiment uses an operation knob provided on an air conditioning control panel of an automobile as an operation unit, a damper provided in an air conditioning duct as an operated unit, and rotates the operation knob to rotate the rotation axis of the damper. It is transmitted to RS (see FIGS. 1 and 13 to 16) and used to adjust the rotation of the damper (not shown except for the rotation axis RS).

  FIG. 1 is a perspective view showing a damper-side remote control device 11 provided in an air conditioning duct which is an operated portion. The remote operation device 11 according to the present embodiment is formed by attaching a remote operation cable 51 to a pulley device 21 formed by rotatably holding a pulley 101 with a base 201. The pulley device 21 is arranged in advance on the vehicle body side by connecting the pulley 101 to the rotation shaft RS of the damper. The remote operation cable 51 has a structure in which an outer cable 53 that holds a pair of cables 52 is held by a holder 54 on the end side of the cable 52 (see FIGS. 2 to 8), and is attached to the pulley device 21 later. . That is, the operator inserts the remote control cable 51 through an opening (not shown) for attaching the air conditioning control panel, and widens gaps between various structures. Then, the operator finally guides the remote operation cable 51 to the position of the pulley device 21 installed in advance on the side of a damper (not shown) provided in the air conditioning duct and attaches it to the pulley device 21.

  As shown in FIG. 1, a holder mounting portion 202 that holds the holder 54 of the remote operation cable 51 is formed on the base 201. The remote operation cable 51 is mounted in a state where the holder 54 is held by the holder mounting portion 202, and a pair of cables 52 are wound around the pulley 101 and connected. Thereby, the remote control device 11 can rotate the pulley 101 by relatively moving the pair of cables 52, and transmits the rotation to the rotation shaft RS of the damper connected and fixed to the pulley 101. Can do.

Hereinafter, the remote operation cable 51 will be described, the pulley device 21 will be described, and finally, the procedure for mounting the remote operation cable 51 on the pulley device 21 will be described.
(1) Remote operation cable 51
First, the remote operation cable 51 will be described.

  FIG. 2 is a plan view showing the distal end portions of the outer cable 53 and the pair of cables 52. The outer cable 53 holds a pair of cables 52 adjacent to each other so as to be slidable. The pair of cables 52 thus held by the outer cable 53 has a connecting member 55 at the tip. These connecting members 55 are structures for connecting the pair of cables 52 to the pulley 101, and are formed in a ring shape. Therefore, the connecting member 55 has an insertion hole 56 in the central portion thereof. These insertion holes 56 partially have a flat surface 57 and are formed in a non-circular shape.

  As shown in FIG. 1, the cable 52 and the outer cable 53 formed in this way are slidably accommodated in a holder 54 having an elongated shape on the distal end side of the cable 52.

  FIG. 3 is a plan view showing the lower member 54 a of the holder 54. The upper member 54b (see FIGS. 1 and 7 to 8) covers the upper surface of the lower member 54a of the upper surface opening that holds and holds the distal end portions of the pair of cables 52 together with the distal end portion of the outer cable 53. It is formed by.

  The lower member 54 a has a storage portion 58 in which the pair of cables 52 and the outer cable 53 are stored. And it has the holding | maintenance part 59 in the one end side. The holding portion 59 has a pair of parallel plate-like portions 59a protruding from both side ends on one end side of the lower member 54a along the extending direction of the lower member 54a, and the inner end of the plate-like portion 59a is the outer shape of the connecting member 55. And a curved contact portion 59b formed by being curved and cut out so as to correspond. The curved contact portion 59 b holds the connecting member 55 pulled toward the other end of the lower member 54 a by the cable 52, and positions the connecting member 55 at the end of the holder 54. The holding portion 59 communicates with the storage portion 58 in the inside thereof and holds the connecting member 55 provided on the pair of cables 52 in an exposed state. In this case, the holding part 59 not only holds the connecting member 55 but also the axial directions of the pair of insertion holes 56 formed in the pair of connecting members 55 forming a link shape are parallel to each other in the vertical direction. Thus, the connecting member 55 is held (see FIG. 7).

  Such a lower member 54a has holding claws 60 at its four corners as viewed from above. These holding claws 60 have a role of fixing the upper member 54b to the lower member 54a. In other words, when the upper member 54b is attached to the lower member 54a, the holding claw 60 is elastically deformed by being pressed by the upper member 54b, and is restored by joining the upper member 54b to the opening portion of the lower member 54a, and the upper member 54b. Clamp.

  Further, the lower member 54 a is formed with a first claw portion 61 and a second claw portion 62 that are positioned in the vicinity of the holding claw 60. The first claw portion 61 is on the end portion side opposite to the end portion side on which the holding portion 59 is provided, and the second claw portion 62 is on the end portion side on which the holding portion 59 is provided. Has been placed. The first claw portion 61 and the second claw portion 62 are formed so as to be elastically deformable up and down by partially cutting away the bottom surface of the lower member 54a. In FIG. 3, the notched portion is indicated by a notched portion CP.

  Further, the lower member 54 a has a flange portion 63 on the back side wall of the holding portion 59. The collar portion 63 is a disk-shaped member whose axial direction is directed horizontally, and is integrally formed with the holding portion 59 via a spacer 64. Therefore, the collar portion 63 is separated from the holding portion 59 by the thickness of the spacer 64.

  Further, the lower member 54a has a positioning convex portion 65 at an intermediate portion on the back side thereof. The positioning convex portion 65 is a member slightly protruding from the back surface of the lower member 54a.

  FIG. 4 is a side view showing the lower member 54 a of the holder 54. As shown in FIG. 8, the 2nd nail | claw part 62 protrudes upwards rather than the bottom face of the accommodating part 58 currently formed in the inside of the lower member 54a. Since the second claw portion 62 and the first claw portion 61 have the same height, the first claw portion 61 is also formed inside the lower member 54a, although not shown in FIG. It protrudes upward from the bottom surface of the storage portion 58.

  FIG. 5 is a rear view showing the lower member 54 a of the holder 54. Referring to FIG. 5, it can be seen that the collar portion 63 has a disk shape when viewed from the back side of the lower member 54 a.

  6 is a cross-sectional view taken along line AA in FIG. Referring to FIG. 6, it can be seen that the periphery of the first claw portion 61 and the second claw portion 62 is a notch CP.

  In addition, referring to FIG. 6, the claw shapes of the first claw portion 61 and the second claw portion 62 can be understood. 6, the first claw portion 61 has inclined surfaces on both the left and right sides, whereas the second claw portion 62 has a surface on which only the left surface is inclined. Has been. For convenience of explanation, the left side surface of the first claw portion 61, that is, the surface opposite to the second claw portion 62 is referred to as an inclined surface 61a. The inclined surface 61a is inclined toward the second claw portion 62 toward the upper end. The right-side surface of the second claw portion 62 that is not inclined is referred to as a vertical surface 62a.

  FIG. 7 is a plan view of the remote operation cable 51 that virtually shows the outer cable 53 and the pair of cables 52 held inside. As described above, the upper member 54 b is attached to the upper surface opening portion of the lower member 54 a in a state where the cable 52 and the outer cable 53 are stored in the storage portion 58. At this time, the upper member 54b is clamped by holding claws 60 provided at the four corners of the lower member 54a.

  The connecting member 55 provided at the end of the cable 52 is exposed to the outside even when the upper member 54b is attached to the lower member 54a. At this time, the holding portion 59 stores and holds the connecting member 55 so that the axial directions of the pair of insertion holes 56 are parallel to each other in the vertical direction.

  In addition, as shown virtually in FIG. 7, the outer cable 53 is formed with a fitting recess 66. The outer cable 53 is positioned with respect to the holder 54 by the first claw portion 61 formed on the lower member 54 a of the holder 54 being fitted into the fitting recess 66. The fitting recess 66 is formed in the outer cable 53 in a concave shape, and may be indented or hole-shaped as long as it is concave.

  FIG. 8 is a longitudinal front view of the remote control cable 51. Referring to FIG. 8, it can be seen that the first claw portion 61 formed in the lower member 54 a of the holder 54 is fitted in the fitting recess 66 formed in the outer cable 53. Further, as shown in FIG. 8, the storage portion 58 reaches the holding portion 59 and expands into a trumpet shape.

  Here, the effect of the remote operation cable 51 will be described.

  Since the cable 52 and the outer cable 53 are only housed in the housing portion 58 of the holder 54, the outer cable 53 and the holder 54 are slidable relative to each other in the longitudinal direction. 7 and 8, for example, when the holder 54 is moved to the left while the position of the connecting member 55 remains unchanged, the holder 54 slides to the left with respect to the cable 52 and the outer cable 53. In this case, the first claw portion 61 formed on the lower member 54 a of the holder 54 has an inclined surface 61 a on the left side surface, so that the fitting recess 66 of the outer cable 53 is moved with the movement of the holder 54. And the holder 54 can be slid relative to the cable 52 and the outer cable 53. When the holder 54 moves to the left with respect to the cable 52 and the outer cable 53, the second claw portion 62 formed on the lower member 54 a of the holder 54 is fitted into the fitting recess 66 of the outer cable 53. In this position, the movement of the holder 54 in the left direction is restricted. This is because the right side surface of the second claw portion 62 is formed as a vertical surface 62a that stands vertically. Therefore, the cable 52, the outer cable 53, and the holder 54 are connected to the second claw portion from the position (first position) where the fitting recess 66 formed in the outer cable 53 is fitted to the first claw portion 61. Thus, they can slide to each other up to the position where they are fitted to 62 (second position).

  Here, in the first position, the holder 54 is positioned at a holding portion 59 that covers the pair of cables 52 extending from the outer cable 53 and has a connecting member 55 formed at the end. Thus, the first claw portion 61 and the fitting recess 66 form a first position holding portion 67 for holding the outer cable 53 in the holder 54 so that the outer cable 53 can be released at the first position (see FIG. 8).

  Further, in the second position, the holder 54 is wound around a guide groove 102 (see FIGS. 9 to 10 and 13 to 16) in which a pair of cables 52 extending from the outer cable 53 are formed on the outer periphery of the pulley 101. Expose only the length attached. Thus, the second claw portion 62 and the fitting recess 66 form a second position holding portion 68 that holds the outer cable 53 on the holder 54 at the second position (see FIG. 8).

As described above, according to the present embodiment, when the remote control cable 51 is inserted from the opening (not shown) for attaching the air conditioning control panel and the gaps between various structures are broken, the outer cable The tip end portion of the cable 52 held by 53 can be held by the holder 54. In addition, in this case, the cable 52 and the outer cable 53 can be positioned at the first position by the first position holding portion 67, and the unexpected protrusion of the tip of the cable 52 can be suppressed. Therefore, it is possible to prevent the tip of the flexible cable 52 from drooping due to gravity, and to improve the workability of the operation of passing the cable 52 through the gaps between various structures.
(2) Pulley device 21
Next, the pulley device 21 will be described.

  FIG. 9A is a front view of the pulley 101 showing a state in which the two base elements 103 are folded, and FIG. 9B is a state in which the two base elements 103 are unfolded. FIG. 10A is a left side view of the pulley 101 showing a state in which the two base elements are folded, and FIG. 10B is a state in which the two base elements are unfolded.

  The pulley base 104 is the basis of the pulley 101. The pulley base body 104 has two arc surfaces 105 on both sides of a straight line passing through the rotation center of the pulley 101, and a pair of guide grooves 102 are formed on each of the arc surfaces 105. These guide grooves 102 are formed by rails capable of guiding the cable 52 of the remote operation cable 51. Such a pulley 101 has a connecting hole 106 at its rotational center position. The connection hole 106 is formed so as to be able to prevent rotation of a rotation shaft RS of a damper (not shown) provided in the air conditioning duct.

  The pulley 101 has a folding mechanism 107. The folding mechanism 107 folds the pulley base body 104 into two parts by two base element elements 103 each having a guide groove 102 so that it can be folded. However, the pulley base 104 is not completely divided into two in the same shape. As is apparent from FIGS. 9A and 9B and FIGS. 10A and 10B, the guide groove 102 is formed. Only the part to be formed is divided into two. Therefore, one base element 103 does not change its front shape according to whether or not it is folded, and the connection hole 106 is formed only in this base element 103. For convenience of explanation, the base element 103 whose front shape is not changed according to the presence or absence of folding is simply called a base element 103a, and the other base element 103 is called a folded base element 103b.

  The folding mechanism 107 rotatably connects two base elements 103 (base element 103a and folding base element 103b) with a hinge 108. The hinge 108 is formed by passing a hinge pin 108c through a hinge member 108a on the base element 103a side and a hinge member 108b on the folding base element 103b side.

  A biasing portion 109 using a coil spring is attached to the hinge pin 108c so as to cover the hinge pin 108c. The urging portion 109 has one end brought into contact with the base element 103a and the other end brought into contact with the folded base element 103b in a state in which the accumulated force is unwound and released in the direction. Accordingly, the hinge 108 biases the folding base element 103b in the unfolding direction, thereby biasing the folding base element 103b from the folded state to the unfolded state.

  Here, what is important in the folding mechanism 107 is that when the folding base element 103b is folded, a pair of guide grooves 102 are arranged adjacent to each other in that state (see FIG. 10A).

  Next, the pulley 101 has a pair of cable holding portions 110 that hold the connecting members 55 provided on the pair of cables 52 included in the remote operation cable 51. These cable holding portions 110 are provided at positions adjacent to each other at the end of the pair of guide grooves 102 in a state where the folding base element 103b is folded. Therefore, when the folding base element 103b is deployed, the pair of cable holding portions 110 also expands vertically.

  Such a cable holding part 110 is formed in a rod-like shape to which the connecting member 55 of the pair of cables 52 can be attached by fitting. Moreover, the cable holding part 110 has a flat surface 111 as in the insertion hole 56 of the connecting member 55 having the flat surface 57 (see also FIG. 13). Therefore, the fitting between the cable holding part 110 and the insertion hole 56 of the connecting member 55 is non-circular, and the connecting member 55 can be prevented from rotating with respect to the cable holding part 110.

  Moreover, the cable holding part 110 also has a retaining claw 110a for preventing the connecting member 55 attached to the cable holding part 110 from coming off. These retaining claws 110 a are formed to protrude from the back surface side of the flat surface 111.

  The pulley 101 further includes a deployment lock mechanism 112 and a part of the folding lock mechanism 113.

  The deployment lock mechanism 112 maintains the two base elements 103 (base element 103a and foldable base element 103b) in an open state in a state where the folding base element 103b biased by the biasing portion 109 is deployed. As a structure for that purpose, the deployment lock mechanism 112 clamps the deployed folded base element 103b with a clamp claw 112a provided on the base element 103a. That is, when the folding base element 103b is unfolded, the clamp claws 112a are elastically deformed by being pushed by the unfolding base element 103b and restored in a state where the folding base element 103b is fully unfolded. Clamp 103b. As a result, the two base elements 103 (base element 103a and folded base element 103b) are kept open.

  The fold lock mechanism 113 maintains the two base elements 103 (base element 103a, fold base element 103b) in a folded and locked state against the urging force of the urging portion 109 so as to be unlockable. As a structure for that purpose, the folding base element 103b is provided with a stud 114 standing on the surface which becomes the back surface when folded and becomes the front surface when unfolded, and a through hole 115 is formed in the base element 103a. The through hole 115 is formed in a size and a shape that allow the stud 114 to pass through when the folding base element 103b is folded and does not interfere with the movement locus of the stud 114 when the folding base element 103b is expanded. Therefore, as shown in FIG. 10A, in a state where the folding base element 103 b is folded, the stud 114 penetrates the through hole 115 and protrudes the tip portion to the back side of the pulley base 104. Therefore, by pressing down the stud 114 protruding from the back side of the pulley base 104 from above, the two base elements 103 (base element 103a and foldable base element 103b) can be maintained in the folded locked state. A mechanism for pressing the stud 114 protruding to the back side of the pulley base 104 from above is provided on the base 201 described later.

  The pulley 101 formed in this way has a plurality of mounting claws 116 so as to surround the connecting hole 106 on the back surface side of the pulley base body 104. These mounting claws 116 are structures for rotatably mounting the pulley 101 to the base 201.

  FIG. 11 is a front view showing a state in which the pulley device 21 having the pulley 101 attached to the base 201 is further attached to the remote operation device attachment portion 301. FIG. 12 is a rear view of the pulley device 21. FIG. 13 is a plan view of the pulley device 21 mounted on the remote control device mounting portion 301.

  As described above, the pulley 101 is rotatably attached to the base 201 by the plurality of mounting claws 116 passing through the insertion hole TH1 of the base 201 and engaging with the edge of the insertion hole TH1. A pulley device 21 is formed. The pulley device 21 is fixed at four points by screws 22 to a remote operation device mounting portion 301 disposed in the vicinity of a damper (all not shown) provided in the air conditioning duct on the vehicle body side of the automobile. The base 201 is formed with an insertion hole TH1 that is concentric with the connecting hole 106 of the pulley 101 when the pulley 101 is attached to the base 201. The remote operation device mounting portion 301 is also formed with an insertion hole (not shown) concentric with the connection hole 106 and the insertion hole TH1. Therefore, the insertion hole TH1 of the base 201 and the insertion hole (not shown) of the remote control device mounting portion 301 allow the rotation axis RS of a damper (not shown) provided in the air conditioning duct to pass through the rotation axis RS. It can be connected to the connecting hole 106 of the pulley 101.

  The base 201 has a mounting guide portion 203 that guides the remote operation cable 51 when the remote operation cable 51 is mounted on the pulley device 21. The mounting guide portion 203 is configured such that the connection member 55 of the pair of cables 52 is held by the pair of cable holding portions 110 arranged adjacent to each other by folding the two base elements 103, and the holder 54 of the remote operation cable 51 is attached. It has a groove shape that guides the end portion along the arc surface 105 and reaches the holder mounting portion 202. That is, the mounting guide portion 203 has an initial set hole 204 at the end portion into which the flange portion 63 provided in the remote operation cable 51 is fitted with the pair of cable holding portions 110 held by the pair of connecting members 55. is doing. And the groove | channel which makes the mounting | wearing guide part 203 makes the width | variety of the groove | channel connected to the initial setting hole 204 narrower than the diameter of the collar part 63, and the width | variety which can pass the spacer 64 located in the base of the collar part 63 It is set. The groove forming the mounting guide portion 203 finally ends at the set hole 205, and the holder 54 of the remote control cable 51 reaches the holder mounting portion 202 with the spacer 64 reaching the set hole 205. It is formed so that it can be tightened.

  The mounting guide portion 203 starting from the initial set hole 204 formed in this way and having the set hole 205 as an end point has a plurality of reverse feed preventing claws 206 disposed in the groove. These reverse feed prevention claws 206 are pushed and elastically deformed by the spacer 64 moving from the initial set hole 204 toward the set hole 205, and allow the spacer 64 to move in that direction, but move in the opposite direction. The spacer 64 is not elastically deformed and restricts the movement of the spacer 64 in the reverse direction.

  The holder mounting portion 202 is formed by a pair of holding arms 207 that hold the holder 54 of the remote operation cable 51 with a lower support, and a fitting holding portion 208 into which a positioning convex portion 65 formed on the back side of the holder 54 is fitted. Has been. Therefore, the holder mounting portion 202 is provided on the holder 54 of the remote operation cable 51 and guides the spacer 64 of the collar portion 63 guided to the mounting guide portion 203 to the set hole 205 and mounts the holder 54 on the pair of holding arms 207. The holder 54 can be securely held only by placing it.

  Here, the fold lock mechanism 113 described above will be described. As described above, the base 201 is provided with a mechanism for pressing the stud 114 protruding from the back side of the pulley base 104 from above. This mechanism is a latch mechanism 209. That is, as shown in FIG. 12, the base 201 is formed with an insertion hole TH <b> 2 through which the stud 114 (see FIG. 10A) that penetrates the through hole 115 in the pulley 101. The insertion hole TH2 is formed in the same shape and size as the position of the through hole 115 of the pulley 101. The base 201 has a mounting recess 210 formed on the back surface thereof, and a latch arm 211 as a latch member is rotatably mounted in the mounting recess 210. The latch arm 211 has an L shape, and one end thereof is further bent into a sickle shape. This sickle-shaped portion forms a sickle portion 211a that can be displaced between a position crossing the through hole 115 of the pulley 101 (latch position) and a retreat position (latch release position) according to the rotation of the latch arm 211. ing. The sickle portion 211a is positioned at the latch position when the latch arm 211 rotates counterclockwise, and at the latch release position when it rotates clockwise on the paper surface of FIG. The sickle portion 211a presses the stud 114 protruding from the back side of the pulley base body 104 in the state where the folding base element 103b is folded at the latch position, and the biasing force of the biasing part 109 included in the pulley 101. Against this, the two base elements 103 (base element 103a, folded base element 103b) are maintained in the folded locked state. Then, the sickle portion 211a is retracted from the stud 114 at the latch release position, and the locked state of the two base elements 103 (base element 103a and folding base element 103b) is released.

  Such a latch arm 211 normally positions the sickle portion 211a at the latch position. This is realized by the locking projection 212 formed in the mounting recess 210 of the base 201. The latching convex portion 212 is provided at an intermediate position between the latch arm 211 in the latch position and the latch arm 211 in the latch release position, and is provided on the action portion 211b on the end opposite to the sickle portion 211a of the latch arm 211. Engage to prevent the latch arm 211 from moving from the latch position to the latch release position and from the latch release position to the latch position. The latch arm 211 is made of an elastically deformable resin material. Therefore, when a strong rotational force is applied to the latch arm 211, the engagement between the action portion 211 b of the latch arm 211 and the locking convex portion 212 is released by elastic deformation of the latch arm 211. The action portion 211 b of the latch arm 211 is bent toward the pulley 101, and its tip extends through the through groove 210 a provided in the base 201 and extends to the side position of the pulley 101.

  The fold lock mechanism 113 also has a latch release mechanism 213. The latch release mechanism 213 is formed by the positional relationship of the action part 211 b of the latch arm 211 with respect to the mounting guide part 203. That is, the action part 211 b of the latch arm 211 is positioned in the vicinity of the set hole 205 on the moving track of the holder 54 guided by the mounting guide part 203. Therefore, when the remote operation cable 51 is guided to the mounting guide portion 203, each portion is formed so that the holder 54 pushes down the action portion 211b while the spacer 64 located at the base of the collar portion 63 reaches the set hole 205. Has been. More specifically, the holder 54 of the remote control cable 51 is formed with the lower surface of the holding portion 59 as a push-down portion 69 (see FIGS. 3 to 6 and FIG. 15). The push-down portion 69 is formed so as to push down the action portion 211b of the latch arm 211.

Further, the base 201 has a pulley protective cover 214 positioned in front of the pulley 101. The pulley protective cover 214 is disposed at a position facing the mounting guide portion 203 along the movement path of the flange portion 63 of the remote operation cable 51 and the spacer 64 guided by the mounting guide portion 203.
(3) Procedure for Mounting Remote Operation Cable 51 on Pulley Device 21 FIG. 14 is a plan view illustrating a step of connecting the remote operation cable 51 to the pulley device 21 mounted on the remote operation device mounting portion 301. FIG. 15 is a front view illustrating one step of connecting the remote operation cable 51 to the pulley device 21 attached to the remote operation device attachment portion 301.

  In order to attach the remote operation cable 51 to the pulley device 21, the flange 63 provided in the holding portion 59 of the remote operation cable 51 is inserted into the initial setting hole 204 formed in the base 201, and the remote operation cable 51 is Press down as it is. Then, the spacer 64 of the collar portion 63 moves along the groove of the attachment guide portion 203, and accordingly, the connecting member 55 included in the cable 52 is attached to the cable holding portion 110. Then, the retaining claw 110a of the cable holding part 110 prevents the connecting member 55 from coming off. At this time, in the pulley apparatus 21 in which the folding base element 103b is folded, the stud 114 penetrating the through hole 115 of the pulley 101 and the insertion hole TH2 of the base 201 is latched by the latch arm 211 and folded. The folded state of the base element 103b is maintained, and the movement of the stud 114 in the rotational direction is restricted by the insertion hole TH2 of the base 201, so that the pulley 101 is prevented from rotating (see FIGS. 12 and 15). ). Therefore, when the connecting member 55 included in the cable 52 is attached to the cable holding portion 110, a situation in which the pulley 101 is unexpectedly rotated is reliably prevented, and the workability thereof is good.

  In this state, the remote control cable 51 is further moved along the groove of the mounting guide portion 203. In this process, the engagement between the first claw portion 61 of the holder 54 and the fitting recess 66 of the outer cable 53 is released, and the holder 54 of the remote operation cable 51 slides relative to the cable 52 and the outer cable 53. To do. Thereby, the holder 54 is displaced from the first position toward the second position. When the remote control cable 51 is moved so that the spacer 64 of the collar portion 63 is directed toward the set hole 205, the pair of cables 52 are inserted into the guide grooves 102 arranged in parallel, and the holding portion 59 of the holder 54 is inserted into the holding portion 59. The formed push-down portion 69 pushes down the action portion 211b of the latch arm 211 (see FIGS. 12 and 15). As a result, the engagement between the action portion 211b of the latch arm 211 and the locking convex portion 212 of the base 201 is released, the latch arm 211 rotates, and the sickle portion 211a stands from the back surface of the folding base element 103b. The stud 114 is opened. In other words, the latch release mechanism 213 acts to release the latched state of the two base elements 103. Then, in the pulley 101, the urging force of the urging portion 109 is released, and the folding base element 103b is rotated downward. The rotated folding base element 103b elastically deforms the clamp claw 112a and reaches the clamp position by the clamp claw 112a. Thus, the folding base element 103b is locked by the deployment lock mechanism 112 and maintained in the deployed position.

  When the spacer 64 of the flange 63 reaches the set hole 205, the holder 54 is positioned at the second position with respect to the outer cable 53. Therefore, in this state, the second claw portion 62 of the holder 54 is fitted into the fitting recess 66 formed in the outer cable 53, and the holder 54 is fixed to the cable 52 and the outer cable 53.

  Finally, the holder 54 of the remote operation cable 51 is held by the holding arm 207 of the holder mounting portion 202, whereby the assembly of the remote operation cable 51 to the pulley device 21 is completed.

  FIG. 16 is a front view showing the remote operation device 11 on the damper (operated portion) side of the air conditioning duct in which the remote operation cable 51 is connected to the pulley device 21 mounted on the remote operation device mounting section 301.

  Through the steps described above, the pulley device 21 is in a state as shown in FIG. That is, the pulley base body 104 has two arc surfaces 105 in which a pair of guide grooves 102 for guiding the pair of cables 52 are formed on both sides of a straight line passing through the rotation center. The pair of cables 52 are guided by the guide grooves 102 and wound around the pulley 101 to be fixed. Therefore, the pulley 101 can be rotated by moving the pair of cables 52 to each other, and the rotation can be transmitted to the damper of the air conditioning duct.

  Therefore, according to the present embodiment, the pair of cables 52 can be guided alone to the pulley 101 attached in advance to the damper (not shown) side of the air-conditioning duct that is the operated portion. The work of passing the cable 52 through the narrow space becomes easy, and the workability can be improved.

  Further, according to the present embodiment, the pulley base 104 can be simply developed by unfolding the folded pulley base body 104 with the ends of the pair of cables 52 guided to the position of the pulley 101 held by the pair of cable holding portions 110. The cable 52 can be connected to 101 in a wound state. Moreover, the two base elements 103 (the base element 103a and the folded base element 103b) forming the pulley base 104 are urged from the folded state to the unfolded state by the urging portion 109, so that special work is required. The folded pulley base 104 can be developed. Thereby, workability | operativity of the operation | work which winds and connects the cable 52 with respect to the pulley 101 attached previously can be made favorable.

  Further, the base 201 guides the end of the holder 54 along the arc surface 105 of the pulley 101 in a state where the end of the pair of cables 52 is held by the pair of cable holding portions 110 arranged adjacent to each other. A mounting guide portion 203 that reaches the portion 202 is provided. Thereby, the operation | work which mounts | wears with the remote control cable 51 with respect to the pulley apparatus 21 can be made easy.

  Further, since the remote operation cable 51 holds the pair of connecting members 55 so that the axial directions thereof are parallel, the protruding direction of the pair of cable holding portions 110 in the pulley 101 and the shaft of the pair of connecting members 55 are arranged. The direction can be matched. Thereby, the operation | work which mounts the connection member 55 provided in the front-end | tip part of the cable 52 to the cable holding part 110 of the pulley 101 can be made easy.

  Further, according to the present embodiment, the two base elements 103 (base element 103 a and folding base element 103 b) constituting the pulley base 104 are maintained in the locked state folded by the folding lock mechanism 113. In addition, the fold lock mechanism 113 includes a latch arm 211 as a latch member that is rotatably provided at a latch position and a latch release position that latch the two folded base elements 103 and prevent the pulley 101 from rotating. Have. As a result, when the connecting member 55 provided at the tip of the cable 52 is attached to the cable holding part 110 of the pulley 101, the pulley base body 104 is prevented from rotating or opening unexpectedly. The workability of the work can be improved.

  Moreover, the folding lock mechanism 113 has a latch release mechanism 213 that rotates the latch arm 211 in the latch release direction in accordance with the operation of mounting the holder 54 of the remote operation cable 51 on the holder mounting portion 202. As a result, when the remote operation cable 51 is attached to the pulley device 21, the latch of the two base elements 103 constituting the pulley base 104 is released. At this time, since the urging portion 109 urges the pulley base 104 from the folded state to the unfolded state, the pulley base 104 is automatically attached only by attaching the remote operation cable 51 to the pulley device 21. The workability of the work can be improved.

  As described above, according to the present embodiment, the workability of the attaching operation of the remote operation device 11 can be dramatically improved.

  Further, according to the present embodiment, the pair of cable holding portions 110 included in the pulley 101 and the connecting member 55 included in the pair of cables 52 are in a state of being prevented from rotating. For this reason, it is possible to prevent an accident in which the cable 52 is dropped from the guide groove 102 in the process in which one of the folded base elements 103b forming the pulley base 104 is unfolded. Further, when the remote operation cable 51 is assembled to the pulley device 21, the connecting member 55 attached to the cable holding portion 110 does not rotate, so the cable 52 is securely inserted into the guide groove 102 of the pulley 101. It is possible to improve the assembly.

  In addition, according to the present embodiment, the two base elements 103 (the base element 103a and the folded base element 103b) constituting the pulley base 104 are maintained in a state where they are deployed by the deployment lock mechanism 112. As a result, it is possible to reliably prevent the occurrence of a situation where the pulley base 104 once deployed is unexpectedly closed and the pulley 101 is no longer used.
