Description

  The present invention relates to a control cable branching device that branches a control cable for remote operation and operates two or more operation objects at once, or operates one operation object at two locations.

  In an automobile, there are cases where an operation target can be operated from a plurality of locations. For example, there are cases where the rear seat front / rear slide adjustment and reclining angle adjustment can be operated not only by sitting on the seat but also from the rear hatch side.

  In recent years, the number of multi-purpose vehicles called minivans has increased, but many minivans can be operated to tilt the rear seats from the rear hatch when loading luggage. Since the seat cannot be reached from the rear hatch, it is necessary to be able to perform the operation of tilting the seat back and forth and the backrest at two locations on the seat and the rear hatch side. In this case, it is desirable that the operation from the rear hatch side is performed by one operation of front / rear slide, reclining and tilting.

  Therefore, a control cable is used by branch connection in order to remotely control a seat or the like. As the branch connection of the control cable, the inner cords are branched (or aggregated) fixedly connected (see FIG. 4 of Patent Document 1 and Patent Document 2).

  In addition, in a plurality of control cables, a middle-indirect hand has been proposed that can operate a device to be operated alone or in combination by interposing an integrated middle-indirect hand (see Patent Document 3).

  The conventional cable branching device has a branching fixed connection of the control cable inner cable, so there are multiple operation targets, and multiple branching devices are required to enable independent operation. The number of cables increases (see FIG. 21). Therefore, there are problems that the number of parts is large, assembly work and adjustment work increase, and maintenance work of the control cable also increases.

  In addition, the middle-indirect hand of Patent Document 3 cannot provide a control cable for operating a plurality of operation objects collectively, separately from the single operation control cable.

  Next, embodiments of the control cable branching device of the present invention will be described with reference to the drawings.

Embodiment 1
FIG. 1 is a conceptual diagram of a configuration of an operation system using a control cable branching device 40 according to Embodiment 1 of the present invention. The first embodiment shows a case where there are two drive units and one combination operation. For example, not only can the seat reclining operation and tilting operation be performed independently, but both operations can be combined and remotely operated with a single control cable.

  FIG. 2 is a cross-sectional view of the structure of the control cable branching device 40 in the case where there are two drive units and one combination operation according to the first embodiment of the present invention (a), and X in (a). It is -X-ray sectional drawing (b).

  In FIG. 2, the conduits 5a and 5b of the drive unit control cables 2a and 2b and the conduits 6a and 6b of the operation unit control cables 3a and 3b are opposed to both sides of the case 30 by a set of the drive unit and the control cable of the operation unit. The central axes are continuous and fixed so that they are parallel to each other. That is, the control cable 2a of the reclining drive unit and the control cable 3a of the reclining operation unit face each other, and the conduits 5a and 6a face each other so that the control cable 2b of the tilt drive unit and the control cable 3b of the tilt operation unit face each other. The conduits 5b and 6b are fixed facing each other. Further, the conduit 4 of the remote operation control cable 1 is fixed to the side of the case 30 where the conduits 6a and 6b of the operation unit control cables 3a and 3b are fixed (the left side in FIG. 2A).

  The ends 10 of the inner cables 8a and 8b of the drive unit control cables 2a and 2b and the inner cables 9a and 9b of the operation unit control cables 3a and 3b are fixed with an end 10 whose cross section perpendicular to the axis is larger than that of the inner cable. ing. Each end 10 is slidably accommodated in one coupler 20 for each set of drive unit and operation unit. The couplers 20a and 20b are formed with a cylinder portion 21 on which the end 10 can slide, and are engaged at both ends so that the end 10 does not come off.

  The two couplers 20 a and 20 b corresponding to the reclining operation and the tilt operation are accommodated in parallel with a sheath portion 31 formed in the case 30. The plate 11 is installed so as to contact one end face of the two couplers 20a and 20b, and the end of the inner cable 7 of the remote control cable 1 is engaged with the plate 11 so as not to come off. . In practice, when assembling the remote control cable, the nipple end 13 is fixed to the end of the inner cable 7 after passing the plate 11 through the inner cable 7. The plate 11 may be provided with a slit through which the inner cable 7 of the control cable 1 is passed, and may be fitted later. The plate 11 is also provided with slits for passing the inner cables 8a and 8b of the reclining drive unit and the tilt drive unit control cables 2a and 2b, which are omitted in FIG.

  In order to realize the configuration of FIG. 2, it is necessary to divide the case 30 as appropriate, and slits and holes for passing the inner cable control cable, but these are problems in design and manufacturing. Omitted.

  Next, the operation and action will be described with reference to FIGS. FIG. 3 shows a case where only the reclining operation lever 60a (not shown) is operated independently. When the reclining operation lever 60a is operated, the inner cable 9a for reclining operation is pulled in the lever direction (left side in FIG. 3). Since the end 10 of the inner cable 9a for the reclining operation is engaged with the coupler 20a, the coupler 20a is pulled toward the reclining operation lever 60a and simultaneously engaged with the opposite side of the coupler 20a. Pull the inner cable 8a of the control cable 2a connected to the section 50a (not shown). Since the connector 20b and the plate 11 are in contact with each other, the operation of the reclining operation lever is not transmitted to the plate 11, and only the reclining drive unit 50a is operated.

  FIG. 4 shows a case where only the tilt operation lever 60b (not shown) is operated independently. When only the tilt operation lever 60b is operated in the same manner as the reclining operation of FIG. 3, the operation is not transmitted to the plate 11, and only the tilt drive unit 50b (not shown) operates.

  FIG. 5 shows a case where a remote lever 70 (not shown) is operated. When the remote lever 70 is operated, the inner cable 7 of the remote operation control cable 1 is pulled to the operation lever side (left side in FIG. 5). Since the end of the inner cable 7 of the remote control cable 1 is engaged with the plate 11, the plate 11 is pulled toward the remote lever. Since the plate 11 is in contact with the end faces of the two couplers 20, the two couplers 20a and 20b are urged toward the remote lever 70 by the operation of the plate 11. The inner cable 8a of the control cable 2a connected to the reclining drive unit 50a and the inner cable 8b of the control cable 2b connected to the tilt drive unit 50b are engaged with the two couplers 20a and 20b. Both are pulled to the remote lever 70 side, and both the reclining drive unit 50a and the tilt drive unit 50b are operated. Therefore, two operation objects can be operated by operating the remote lever 70.

  At this time, since no force is applied to the inner cable 9a of the control cable 3a for reclining operation and the inner cable 9b of the control cable 3b for tilt operation, the inner cables 9a, 9b of the control cables 3a, 3b do not move. The couplers 20a and 20b slide outside the end 10 and are left behind.

  When the two operation objects in FIG. 5 are activated, on the other hand, for example, when only the tilt operation is released (that is, the tilt operation is released on the tilt drive side), only the reclining operation lever is operated as shown in FIG. It will be in the same state as you did. In many cases, since a spring (not shown) acting in the direction of releasing the operation is attached to the drive unit side, the reclining operation is also released by the force of the spring (that is, the state returns to the state of FIG. 2). In the case where a spring acting in the direction of releasing the operation is not provided on the drive unit side, a spring that urges the plate 11 toward the end of the inner cable may be provided in order to stabilize the plate 11.

  Thus, according to the present invention, each operation object can be operated independently, and a plurality of operation objects can be operated together with a single control cable. When the control cable branching device 40 according to the present embodiment is used, two control cables are required as compared with the conventional example of FIG.

  FIG. 6 shows an example of the control cable branching device 40 when there are three operation objects (drive units).

  In the case where there are three drive units, as shown in FIG. 6B, the couplers 20a, 20b, and 20c can be arranged so as to be at the vertices of a triangle in the cross section. Since the operation of the remote lever 70 and the reaction force of each drive unit need only be balanced, the arrangement of the couplers 20a, 20b, and 20c may not be an apex of an equilateral triangle, and may be arranged linearly in some cases. . It is preferable for the operation balance of the device that the sum of the moments of reaction force of each drive unit centering on the remote control cable 1 is zero, but if it can be operated even if it is not particularly arranged as such. Good.

  FIG. 2 shows the case where there are two operation objects, and FIG. 6 shows the case where there are three operation objects. However, the number of operation objects need not be limited to these, and the configuration can be similarly made even when there are three or more operation objects. .

  FIG. 10 is a structural cross-sectional view showing a control cable branching device having a minimum configuration according to the first embodiment of the present invention. In FIG. 10, there is one drive unit, and the drive unit can be operated from two places (the operation unit control cable 3a or the remote operation control cable 1). In this case, the number of control cables is not reduced as compared with the conventional branching device, but the inner cable of each control cable is not fixedly connected, so one (for example, the operation unit control cable 3a) is operated. Even in this case, since no bending moment is applied to the inner cable, the movement is smooth and an increase in the number of times the inner cable can be used can be expected.

Embodiment 2
A second embodiment of the present invention will be described with reference to FIG. In the second embodiment, it is assumed that the control cable branching device 40 is provided with two plates 11a and 11b and remote control cables 1a and 1b (not shown).

  In FIG. 7, it is the same as FIG. 6 that there are three operation objects (drive units), but there are two plates 11, each plate 11a, 11b being connected to another remote control cable 1a, 1b. The difference is that the inner cords 7a and 7b are engaged. In FIG. 7, the plate 11a covers the cross sections of the three couplers 20a, 20b, and 20c so as to simultaneously operate the three driving units as in FIG. The plate 11b is in contact with the end faces of the two couplers 20a and 20b among the three drive units. The plate 11a and the plate 11b overlap each other at the projected portions of the couplers 20a and 20b with which the plate 11b is in contact. The end face of the coupler 20c that is not in contact with the plate 11b is extended by the thickness of the plate 11b and is in contact with the plate 11a.

  The plate 11a is engaged with the inner cable 7a of the remote operation control cable 1a at the center, and the plate 11b is engaged with the inner cable 7b of the remote operation control cable 1b at the center of the two connectors 20 in contact.

  When pulling the remote operation control cable 1a, three drive units operate, and when pulling the remote operation control cable 1b, only two drive units operate. Similarly to the first embodiment, each drive unit can be operated independently by operating each operation lever individually.

  For example, there are seat reclining, tilting and sliding drive units, and from the rear hatch side, reclining and tilting must be activated at the same time. In a situation where there is a case where it is not necessary, if the reclining drive unit and the tilt drive unit correspond to the plate 11b and the plate 11a is arranged so as to operate all three, the operation lever can be selected and operated. , The combination operation can be performed at once.

  In the second embodiment, the case where there are three drive units and two and three combinations have been described. However, the present invention is not limited to this, and there are various combinations of three or more drive units. Is possible. For example, the number of driving units is 4, and two of them can be operated together, and the entire four driving units can be operated collectively. In that case, there are three plates 11.

Embodiment 3
A third embodiment of the present invention will be described with reference to FIG. The third embodiment corresponds to the case where there is a target control cable that should be operated only by remote control.

  For example, the seat slide operation or folding operation is performed by directly operating the drive unit with a foot pedal or the like without using a control cable, but the slide operation or folding operation is desired even by remote operation.

  In FIG. 8, it is the same as that of FIG. 6 that there are three drive units, but there is no control cable 3a that operates independently for one of the drive units (for example, a seat slide). Therefore, the coupler 20a (see FIG. 6) is omitted for the control cable 2a of the drive unit that does not have an independently operated control cable, and the end 10 of the control cable 2a is directly engaged with the plate 11. It is arranged. That is, the end 10 of the inner cable 8a of the control cable 2a of the seat slide driving unit is directly engaged with the plate 11.

  About a drive part with operation part control cable 3b, 3c, it can operate independently, respectively. Further, when a remote lever (not shown) is operated, the three driving units are activated simultaneously.

  In this way, for the drive unit without the operation unit control cable 3a, the coupler 20a can be omitted, and the number of parts and assembly man-hours can be reduced.

Embodiment 4
A fourth embodiment of the present invention will be described with reference to FIG. In the fourth embodiment, there is provided a control cable branching device 40 capable of operating a plurality of objects collectively in both directions when the drive unit is not automatically released by a spring or the like.

  9, it is the same as FIG. 6 that there are three drive units, but the two plates 11a and 11b are disposed in contact with the surfaces on both sides of the couplers 20a, 20b, and 20c, respectively. The plate 11a is disposed on one side (right side in FIG. 9) of the connector 20, and is attached to the inner cable 7a of the remote control cable 1a (not shown) fixed to the opposite side of the case 30 (left side in FIG. 9). Is engaged. The plate 11b is disposed on the other surface (the left side in FIG. 9) of the couplers 20a, 20b, and 20c, and engages with the inner cable 7b of the remote control cable 1b (not shown) fixed to the right side of the case 30. ing.

  In the fourth embodiment, the plate 11a is in contact with all the three connectors 20a, 20b, and 20c, and the plate 11b is in contact with the two connectors 20a and 20b. Accordingly, when the remote operation control cable 1a is operated, the three drive units are activated, and when the remote operation control cable 1b is operated from that state, the two drive units are deactivated. The drive portion of the control cable 2c engaged with the coupler 20c that is not in contact with the plate 11b may be automatically deactivated.

  As well as the drive part of the control cable engaged with the coupler 20c not in contact with the plate 11b, the drive part control cables 2a and 2b engaged with the couplers 20a and 20b in contact with the plate 11b. The drive unit can also be operated independently. For example, when the operation unit control cable 3b is operated, the plate 11b is also moved to the left side of the case 30, but since the plate 11b is only in contact with the connector 20, no force is applied to the other connectors 20, and the operation unit control is performed. The drive unit other than the drive unit of the drive unit control cable 2b facing the cable 3b does not operate. The same applies to the operation unit control cable 3a.

  Therefore, in the fourth embodiment, a plurality of objects (drive units) can be collectively operated in both directions, and the number of control cables can be reduced as compared with the conventional branch device.

Embodiment 5
Next, as another aspect of the present invention, a control cable branching device in which the coupler is a pulley will be described with reference to an example. 11A and 11B are external views showing a control cable branching device 40 according to Embodiment 5 of the present invention, where FIG. 11A is a left side view, FIG. 11B is a front view, and FIG. 11C is a right side view. is there. 12 is a cross-sectional view of the control cable branching device 40 shown in FIG. FIG. 13 is an exploded perspective view of the control cable branching device 40 shown in FIG. In the fifth embodiment, the member corresponding to the coupler is constituted by a pulley. In addition, there is no member corresponding to the plate 11, and independent operation and combination operation are realized by a protrusion and a depression formed on the side surface of the pulley instead.

  The branching device 40 includes a case 30a and a case 30b, and is housed so that two pulleys 80a and 80b rotate around the same central axis (FIG. 13). A hub 89 is formed on the side surfaces of the pulleys 80a and 80b so as to be fitted into the holes 32a and 32b formed at the centers of the cases 30a and 30b (FIG. 12). A boss 90 is formed on one side (FIG. 16) and a receiving portion 91 is formed on the other side (FIG. 17) so that the rotation axis does not shift on the adjacent side surface of 80 b. Each hub 89 fits into the holes 32a and 32b of the cases 30a and 30b, and the boss 90 fits into the receiving portion 91, and the two pulleys 80a and 80b rotate independently of the cases 30a and 30b.

  Two pulleys 80a and 80b are formed on the outer periphery with two grooves 81 and 82, respectively, with which the inner cable engages. One of the two grooves (82a, 82b) is formed with a recess 83 that engages the ends of the inner cables 8a, 8b of the drive unit control cables 2a, 2b, and the other one (81a, 81b). Is formed with an end face 84 with which the ends of the inner cables 9a and 9b of the operation part control cables 3a and 3b are engaged, and a part (small diameter part 85) having a small pulley outer diameter formed on the end face 84 is formed. Yes. One pulley 80a (see FIG. 13) close to the mounting surface of the branching device 40 is further provided with an end surface (second end surface 86) with which the inner cable 7 of the remote control cable 1 is engaged and a second end surface 86 thereof. A narrow small diameter portion 85 is formed (FIG. 16).

  On the adjacent side surfaces of the two pulleys 80a and 80b, a protrusion 87 is formed on one side surface (FIG. 17), and a recess 88 forming a concentric part centering on the center of the pulley outer diameter is formed on the other side surface. It is formed (FIG. 16). The protrusion 87 fits into the recess 88, and the two pulleys 80a and 80b rotate independently within the range of the recess 88. When the protrusion 87 contacts the end of the recess 88, the other pulley 80a rotates as the other pulley 80a rotates. The pulley 80b also rotates. In the fifth embodiment, the pulley 80b on which the protrusion 87 is formed can be independently operated and moves independently within the range of the depression 88, and the pulley 80a on which the depression 88 is formed corresponds to the combination operation cable. Yes. The protrusion 87 and the recess 88 may be reversed, and the protrusion 87 may be formed in the combination operation pulley 80a, and the recess 88 may be formed in the independent operation pulley 80b.

  Two drive unit control cables 2a, 2b are connected to the upper left of the case 30a shown in FIG. 11 (b), and the inner cords 8a, 8b are engaged with the outer peripheral grooves 82a, 82b of the pulleys 80a, 80b, respectively. The nipple end 13 formed in the portion is engaged with the recess 83 of each of the two pulleys 80a and 80b. The two operation unit control cables 3a and 3b are connected to the upper right of the case 30a shown in FIG. 11B, and the inner cables 9a and 9b are hooked on the outer peripheral grooves 81a and 81b of the pulleys 80a and 80b. The nipple end 13 formed in the portion is engaged with an end face 84 formed on the outer periphery of the two pulleys 80a and 80b. Then, the remote operation control cable 1 is connected to the lower left of the case 30a shown in FIG. 11B, and the inner line 7 of the remote operation control cable 1 is engaged with the inner line 9a of the operation unit control cable 3a of the pulley 80a. The nipple end 13 formed at the end of the outer peripheral groove 81 a is engaged with the second end face 86.

  The drive unit control cable 2a and the operation unit control cable 3a constitute one set, and the drive unit control cable 2b and the operation unit control cable 3b constitute another set. Further, the remote operation cable 1 does not form a set with an independent drive unit control cable.

  When the control cable branching device 40 according to the fifth embodiment is attached to a vehicle or the like, each cable is attached to the branching device 40 and assembled in advance, and a square hole formed at the center of the two pulleys 80a and 80b is formed. A rod is inserted and fixed so that the pulleys 80a and 80b do not rotate, and the length of each control cable is adjusted by attaching the end on the drive unit side or the operation unit side. As long as the pulleys 80a and 80b can be fixed so as not to rotate, the fixing method may not be a square hole provided at the center of the pulley.

  Next, the operation and action will be described with reference to FIGS. Pulling the inner cable 9b of the operation unit control cable 3b from a state where none of the operation unit control cables 3a and 3b and the remote operation control cable 1 are operated (FIG. 18A), the pulley 80b rotates, The inner cable 8b of the drive unit control cable 2b is pulled to the operation side to operate the drive unit. At this time, since the protrusion 87 moves freely in the recess 88, the pulley 80a does not rotate and the drive unit control cable 2a is not operated (FIG. 18B).

  Pulling the inner cable 9a of the operation unit control cable 3a from the state in which none of the operation unit control cables 3a, 3b and the remote operation operation control cable 1 are operated (FIG. 19A), the pulley 80a rotates. Then, the inner cable 8a of the drive unit control cable 2a is pulled to the operation side, and the drive unit is operated. At that time, the protrusion 87 contacts the end of the recess 88, and the pulley 80b also rotates together with the pulley 80a. As a result, the drive unit control cable 2b is pulled to the operation side, and the drive unit is operated (FIG. 19B). In this case, the inner cable 9b of the operation unit control cable 3b and the inner cable 7 of the remote operation control cable 1 are left behind. The pulleys 80b and 80a move the inner cable 9b of the operation unit control cable 3b and the inner cable 7 end of the remote control cable 1 so that the inner cables 9b and 7 do not protrude into the case. A small diameter portion 85 is formed in each of the pulleys 80a and 80b. Considering the rotating pulley as a reference, the inner cable 9b of the operation unit control cable 3b that does not move and the inner cable 7 of the remote operation control cable 1 are respectively released to the small diameter part 85.

  Next, when the remote operation unit control cable 1 is pulled from a state where none of the operation unit control cables 3a and 3b and the remote operation operation control cable 1 are operated (FIG. 20A), the pulley 80a rotates, Since the protrusion 87 is in contact with the end of the recess 88, the pulley 80b also rotates together with the pulley 80a. As a result, the inner cable 8a of the drive unit control cable 2a and the inner cable 8b of the drive unit control cable 2b are both pulled to the operation side and the drive unit is operated (FIG. 20). At this time, the inner cords of the operation unit control cables 3a and 3b are left behind by the small diameter portions 85 of the pulleys 80a and 80b and do not move.

  That is, in the fifth embodiment, it is possible to operate the drive unit control cables 2a and 2b at the same time regardless of whether the operation unit control cable 3a is operated or the remote operation control cable 1 is operated. When the operation unit control cable 3b is operated, only the drive unit control cable 2b is operated. In the fifth embodiment, the remote operation control cable 1 having the same function as the operation unit control cable 3a is provided at another location.

  According to the fifth embodiment, since the mounting angle of each control cable can be changed, the control cable can be efficiently installed in a narrow space like a vehicle.

  In the fifth embodiment, the case where the outer diameters of the two pulleys 80a and 80b are equal is shown. However, by changing the outer diameters of the two pulleys 80a and 80b, one drive unit having a different operation amount is provided. Can be summarized in operation.

  In the fifth embodiment, the remote operation control cable 1 is engaged with the same pulley 80a as the operation unit control cable 3a using two pulleys 80a and 80b. By separately providing a pulley for remote operation, it is possible to operate each of the two drive units independently as in the first embodiment, and to operate the two drive units together in the remote operation. It can also be configured. In that case, the pulley with which the remote operation control cable 1 is engaged is placed at the center of the two independent operation pulleys 80a and 80b with the outer peripheral groove as one line. Since the pulley for remote control has a thin outer peripheral groove, the relationship between the protrusion and the depression is opposite to that of the fifth embodiment, the protrusion 87 is provided in the central pulley, and the depressions 88 are provided in the pulleys on both sides. May be provided so that the indentation 88 is moved by the protrusion 87. Alternatively, the recess 88 may be a through hole. Further, if the positional relationship in which the protrusion 87 and the indentation 88 are in contact with each other is made different on both sides, a step (time difference) can be added to the operation of the drive unit in the remote operation. When there are three or more pulleys, a shaft may be provided at the center in order to stabilize the rotation. The shaft can be fixed to any pulley. In addition, it is good also as a booster mechanism which makes the operation force of remote operation small by enlarging the outer diameter of the pulley for remote operation.

  As described above, in the first to fifth embodiments, the case where the drive unit is 2 or 3 has been described by way of example. However, the present invention is not limited to these cases, and various combinations of two or more drive units. It can be applied and configured.

  Note that the end of each control cable only forms a normal nipple end, and can be easily manufactured. In addition, since the length of each control cable can be adjusted independently, assembly and adjustment are easy.
