Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a selection operation device for selecting either one of two systems of cables with one operation means and independently remotely operating two operation objects via these cables. More particularly, the present invention relates to a selection operation device that is employed when an opener for unlocking a trunk lid and an opener for unlocking a fuel lid are operated with a single operation lever from a driver seat of an automobile.
[0002]
[Prior art]
As this type of selection operation device, a push-pull cable transmission force take-out device described in Japanese Patent Publication No. 62-52885 is known. As shown in FIG. 5, this apparatus includes a housing 101 and a slider (sliding member) that is slidable outwardly in a sliding hole 101a formed on the base end side (left side of FIG. 5) of the housing. Moving member) 102. The slider 102 can be moved outward from the state in contact with the bottom 101b of the sliding hole 101a. The ends of the first conduit 103 and the second conduit 104 are fixed to the distal end side (right side in the figure) of the housing 101. An end portion of an operation conduit 105 arranged concentrically with the first conduit 103 is fixed to an outer end portion of the slider 102, and the other end of the operation conduit 105 is a bracket of an operation lever on the driver's seat. It is fixed to.
[0003]
An inner cable 106 of one push-pull cable is slidably accommodated in the first conduit 103 and the operation conduit 105, and is engaged with the slider 102 in the pulling direction in the middle of the inner cable 106. A nipple end (locking piece) 107 is fixed. The slider 102 is provided with a void 108 that allows the nipple end 107 to move within a predetermined range in the axial direction. The end of the inner cable 106 that exits from the first conduit 103 is connected to the first operation target. A cable (pull cable) 109 having one end locked to the slider 102 and the other end locked to the second operation target is slidably accommodated in the second conduit 104. The slider 102 is always biased to the back side of the housing 101 by a spring 110.
[0004]
When the operation end protruding from the other end of the operation conduit 105 of the inner cable 106 is pushed by the operation lever (arrow P1), the device 100 is in contact with the inner wall of the housing 101 because the nipple end 107 is in contact with the inner wall of the housing 101. The middle part of the cable 106 does not move in the pushing direction. Therefore, the length of the inner cable 106 corresponding to the operation conduit 105 is longer, and the free end portion 105a of the operation conduit 105 is pulled in the direction of the arrow P2. Accordingly, the slider 102 also moves in the direction of the arrow P2, the pull cable 109 is pulled, and eventually, the object connected to the tip can be pulled. When the operation side of the inner cable 106 is returned to the original position, the slider 102 is returned to the original position by the spring 110, and the pulling operation of the pull cable 109 is released.
[0005]
Conversely, when the operation end of the inner cable 106 is pulled with the operation lever (arrow P2), only the inner cable 106 moves in the direction of arrow P2 without affecting the pull cable 109, and from the tip of the first conduit 103. The object can be pulled and operated on the protruding part. When the operation end of the inner cable 106 is returned, the operation of the object is released.
[0006]
FIG. 6 shows another use state of the apparatus 100 shown in FIG. This state of use is described in FIG. 8 of the apparatus disclosed in Japanese Patent Publication No. 62-52885. 6, the operating side and the operated side of the inner cable 106 in FIG. 5 are reversed, and when the inner cable 106 is pushed in the direction of the arrow P1, the slider 102 moves in the direction of the arrow P1, One conduit 103 is pushed together with the inner cable 106. Therefore, since the relative operation of the inner cable and the conduit does not occur, the distal end side of the inner cable 106 does not operate the operation target. On the other hand, only the pull cable 109 in the second conduit 104 is operated by operating the slider 102. When the operation end of the inner cable 106 is pulled in the direction of the arrow P2, the operation target at the tip of the inner cable 106 is pulled without affecting the pull cable 109.
[0007]
On the other hand, Japanese Patent Laid-Open No. 9-203252 describes a remote control device 120 shown in FIG. In this apparatus, the inner cable 106 of the push-pull cable in the apparatus of FIG. 6 is divided into two at the nipple end 107 portion, and the operation target side is a pull cable 121. The operation principle is substantially the same as that of the apparatus of FIG. Is the same. However, this has the advantage that the wiring is easier than in the case where the whole is a push-pull cable.
[0008]
[Problems to be solved by the invention]
In the apparatus 100 of FIG. 5, the operation conduit 105 between the operation lever and the slider 103 moves back and forth. The operation conduit 105 is a relatively thick push-pull control cable conduit, and the holding mechanism that allows the conduit to move back and forth is complicated.
[0009]
In the use state of FIG. 6, the operation conduit 105 does not move. However, since the second conduit 104 for the pull cable extends to the front side of the housing 101, the routing route becomes complicated depending on the vehicle type. For example, it is convenient when the housing 101 is disposed between the trunk and the fuel lid, but the wiring is complicated when the housing 101 is disposed in front of the fuel lid.
[0010]
The device 120 of FIG. 7 has an advantage that it is light in weight and easy to route because the use range of the push-pull cable is small. However, the point that the second conduit 104 extends forward is the same as that of FIG.
[0011]
In the present invention, the first conduit 103 and the second conduit 104 extend rearward in parallel as in the device 100 of FIG. 5, and the operation conduit 105 does not move as in the devices of FIGS. Therefore, it is an object of the present invention to provide a selection operation device for two systems of cables that can be easily routed and can easily hold a conduit.
[0012]
[Means for Solving the Problems]
The two-system cable selection operation device according to the present invention (Claim 1) includes a housing, a slider provided in the housing so as to be slidable between a stop position and a moving position on the tip side, and a tip of the slider. A first conduit and a second conduit each having one end fixed so as to extend in the same direction, and a nipple end which is movably provided in a space formed in the slider and engages the slider on the tip side The first cable is slidably accommodated in the first conduit, and one end of the cable is slidably accommodated in the second conduit, and the one end is engaged in the nipple end. A second cable; an operation conduit having one end fixed to the housing; and an operation cable slidably received in the operation conduit and having one end locked to a nipple end. The It is a symptom.
[0013]
The operation cable is preferably a push-pull cable, and the first cable and the second cable are preferably pull cables.
[0014]
[Operation and effect of the invention]
In the selection operation device of the present invention (Claim 1), when the operation cable is operated so as to move toward the slider (push direction operation), the nipple end is pushed and the slider is pushed in the same direction. As a result, the end of the first conduit is pushed, and the first cable in the first conduit is pulled by the reaction force. That is, when the end of the conduit is pushed, the routing route of the first cable becomes long, but the end of the first cable is locked to the housing, so that the tip of the first cable is drawn into the first conduit. It is. As a result, the operation target is pulled. At that time, the second conduit also moves together with the first conduit, but since the second cable is locked to the nipple end, there is no relative movement between the second conduit and the second cable. 2 The cable is not pulled.
[0015]
On the contrary, when the operation cable is pulled, the nipple end moves in the empty space, so that the slider does not move and only the second cable is pulled. As a result, the operation object on the distal end side of the second cable can be pulled.
[0016]
Since the first conduit for guiding the first cable and the second conduit for guiding the second cable extend in the same direction from the front end side of the slider, the wiring is easy and the position of the housing is easily set depending on the vehicle type. become. Even when the operation cable is operated in the pushing direction, the operation conduit does not move because both ends thereof are connected to the stationary member.
[0017]
When the operation cable is a push-pull cable and the first cable and the second cable are pull cables (Claim 2), the operation of the nipple end can be operated with a simple configuration, and the operation is reliable. is there. Further, since the first cable and the second cable become a pull cable extending in parallel, the wiring is further facilitated.
[0018]

A thin cylindrical projection 31 for fixing the operation conduit 16 is provided on the base end 15 side. A hole 32 for passing the operation cable 24 is formed in the proximal wall 15 at a position concentric with the protrusion 31, and a hole 33 for passing the first cable 21 is formed in parallel therewith. Reference numeral 11a in FIG. 2a is an attachment piece for attaching the housing 11 to the mating member. The housing 11 can be manufactured by injection molding of a synthetic resin such as polyacetal.
[0022]
As shown in FIG. 2a, the slider 12 is a block-shaped member having an oval cross-section, and is formed with a hollow 18 having a circular cross-section for slidably receiving the nipple end 19 below, and at the upper part thereof. A through hole 35 through which the first cable 21 passes is formed in parallel with 18. The inner diameter of the through hole 35 is considerably larger than that of the first cable 21. Further, recessed portions 37 and 38 for locking the first conduit 13 and the second conduit 14 are formed on the distal end side.
[0023]
The nipple end 19 is a cylindrical member that is slidably fitted into the space 18 of the slider 12. The nipple end 19 is made of, for example, a zinc alloy, and is fixed (locked) by being cast into the distal end portion of the operation cable 24. However, other fixing methods such as caulking and screwing can be used. The tip of the second cable 22 can also be fixed by casting or the like.
[0024]
In the present embodiment, in order to facilitate the assembly work, as shown in FIG. 2, a locking metal fitting 40 is cast and fixed to the distal end portion of the second cable 22, and the locking is formed on the large-diameter nipple end 19. It is locked in the hole 40a. And the operation cable 24 and the 2nd cable 22 are arrange | positioned concentrically, and the front-end | tip parts are accumulated. Therefore, the slider 12 and the housing 11 are shortened, and the entire apparatus 10 is shortened. However, the locking fittings fixed to the respective cables may be locked to one nipple end, and the second cable 22 and the operation cable 24 may be arranged in parallel.
[0025]
A locking fitting 41 is also fixed to the tip of the first cable 21, and the first cable 21 is locked to the base-side wall 15 of the housing 11 by the locking fitting 41. In this embodiment, the locking metal fitting 41 is fixed to the tip of the first cable 21 in advance, and is passed through the through hole 33 and locked to the wall 15. A groove or slit is formed in the through-hole 33 so as to communicate with the peripheral edge (for example, the upper end) of the wall 15, and the tip of the first cable 21 to which the locking bracket is fixed is locked to the wall 15 using the slit. May be.
[0026]
As the first conduit 13 and the second conduit 14, conventionally known pull control cable conduits are used. Usually, a spiral tube in which a metal wire having a rectangular cross section is spirally wound and a synthetic resin housed in the spiral tube is made. It consists of a liner and a synthetic resin coating coated on the outer periphery of the spiral tube. As the first cable 21 and the second cable 22, a conventionally known inner cable of a pull control cable is used, and it is usually made of a stranded wire of a plurality of metal strands.
[0027]
The operation conduit 16 is also a conventionally known conduit for a push-pull control cable, and has substantially the same configuration as the first conduit 13. The operation cable 24 includes a core in which a plurality of metal strands are brought close to each other, and an armor layer in which metal wires are densely spirally wound thereon. It should be noted that other forms of push-pull control cable conduits and cords can be used.
[0028]
The first conduit 13 and the second conduit 14 are fixed to the slider 12 by being fitted into the recesses 37 and 38 of the slider 12 after the metal caulking ring or cap 45 is put on the tip of the first conduit 13 and the cap 45, respectively. ing. Since both the first cable 21 and the second cable 22 are pull cables, the first conduit 13 and the second conduit 14 do not come out even with such a fixing method. Since the operation cable 24 is a push-pull cable, after being fitted into the cylindrical protrusion 31 of the housing 11, the metal cap 46 is put on the protrusion and crimped.
[0029]
The selection operation device 10 configured as described above can basically be used for the same application as the conventional device shown in FIGS. 5 to 7, and is used, for example, in an automobile opener system 50 shown in FIG. 3. The opener system 50 includes the selection operation device 10 described above, an operation lever 51 for pushing and pulling the operation cable 24 of the device 10, a trunk lid locking mechanism 52 that is released by pulling the first cable 21, It is composed of a fuel lid locking mechanism 53 that is released by pulling the second cable 22. That is, it has both functions of a trunk lid opener and a fuel lid opener. The housing 11 of the selection operation device 10 is usually fixed to an automobile frame or the like, but need not be particularly fixed.
[0030]
The operation lever 51 is pivotally attached to a bracket 54 fixed to a frame of an automobile by a pin 55, and engages with an arc-shaped slit 56 formed in the bracket 54 so that its rotation range is restricted. At the same time, it is urged by the torsion coil spring 57 to always return to the neutral position. The end of the operation conduit 16 is fixed to the bracket 54, and the operation cable 24 is locked to the end of the operation lever 51. The end portion of the first conduit 21 is locked to a bracket 57 in the vicinity of the trunk lid locking mechanism 52, and the end portion 21a of the first cable 21 exits from the first conduit 13 to lock the trunk lid. It is locked to a lever for 52 (not shown). The lever is unlocked by pulling the first cable 21, and when the pulling force is lost, the lever is returned to the original locked position by a return spring. The end portion of the second conduit 14 is locked to a bracket 58 or the like in the vicinity of the fuel lid, and the end portion 22a of the second cable 22 protruding from the end portion is locked to a rod for unlocking the fuel lid. . The rod is also provided with a return spring.
[0031]
Next, with reference to FIGS. 1, 3 and 4, the operation of the selection operation device used in the opener system 50 will be described. First, when the operation lever 51 is in the neutral position, the nipple end 19 at the distal end of the operation cable 24 is located at the back side of the cavity 18 as shown in FIG. 1, and the slider 12 is located at the base side of the housing 11. ing. In this state, neither the first cable 21 nor the second cable 22 is pulled.
[0032]
When the operation lever 51 is pushed down in the arrow S1 direction from this state, the operation cable 24 is pushed in the arrow P1 direction. As a result, the nipple end 19 is also pushed in the direction of the arrow P1, moving the slider 12 to the distal end side as shown in FIG. 4a, and pushing the end of the first conduit 13 in the same direction. However, as shown in FIG. 3, the other end of the first conduit 13 does not move, so the first conduit will bend in the middle. On the other hand, since the tip of the first cable 21 in the first conduit 13 is locked to the housing 11, the other end 21a in FIG. 3 is drawn back into the first conduit 13 (arrow Q1). ). Thereby, the lock of the trunk lid is released.
[0033]
On the other hand, as the slider 12 moves in the direction of arrow P1, the end of the second conduit 14 on the slider side also moves in the direction of arrow P1. However, unlike the first cable 21, the second cable 22 moves in the direction of the arrow P <b> 1 together with the second conduit 14. Accordingly, there is no relative movement between the second conduit 14 and the second cable 22, and the end 22 a of the second cable 22 in FIG. 3 is not drawn into the second conduit 22. That is, the lock of the fuel lid is not released.
[0034]
When the hand is released from the operation lever 51, the operation lever 51 returns to the original neutral position by the biasing force of the torsion coil spring 55. As a result, the nipple end 19 is pulled in the direction of the arrow P2, the force for urging the slider 12 in the direction of the arrow P1 is lost, and the rod for unlocking the trunk lid attempts to return to the original position by the return spring. Thereby, the end portion 21a of the first cable locked to the rod is pulled out in the direction of the arrow Q2. Thereby, a compressive force is applied to the first conduit 13, and the slider 12 returns to the original position as shown in FIG. In addition, the force which the bending of the 1st conduit | pipe 13 returns when the slider 12 moves to the arrow P1 direction also works as a force which returns the slider 12 to an original position.
[0035]
Next, when the operation lever 51 in FIG. 3 is pulled up in the direction of arrow S2, the nipple end 19 is pulled in the direction of arrow P2 through the operation cable 24 as shown in FIG. 4b. As a result, the second cable 22 is also pulled in the direction of the arrow P2, and the lock of the fuel lid in FIG. 3 is released. At that time, the slider 12 does not move while abutting against the wall 15 on the proximal end side of the housing 11, so that the first cable 21 is not affected.
[0036]
When the operation lever 51 is released, the operation lever 51 returns to the neutral position, and the second cable 22 is pulled in the direction of the arrow P1 by the force with which the rod for releasing the lock of the fuel lid is returned by the return spring. Thereby, the state of FIG. 1 is restored.
[0037]
As described above, the selection operation device 10 in FIG. 1 can operate two types of operation objects by selecting and performing the pushing operation and pulling operation of the operation cable 24 as in the conventional device. Moreover, the pull control cable that combines the first conduit 13 and the first cable 21 and the pull control cable that combines the second conduit 14 and the second cable 22 extend in parallel from the leading end side of the slider 12. Is easy. And since the 1st conduit | pipe 13 and the 2nd conduit | pipe 14 move to the same direction together, if necessary, it can also be bundled in the middle. Further, since the operation cable conduit 16 is a push-pull control cable conduit, it is relatively thick and difficult to route with a small curvature, but unlike FIG. 5, both ends can be fixed and do not move. So it is easy to prevent interference with other equipment.
[0038]
In the embodiment of FIG. 3, the case where the apparatus of the present invention is adopted in an automobile opener system is shown. Can be adopted. In the above-described embodiment, the nipple end is operated by a push-pull control cable in which the operation cable 24 and the operation conduit 16 are combined. However, the nipple end is pushed and pulled by other operation means such as a rod. Is also possible. Further, when a spring or the like that constantly biases the slider 12 toward the tip end is used, a pull cable may be employed as the operation cable. Moreover, a push pull cable can also be employ | adopted as the 1st cable 21 and the 2nd cable 22 as needed.
