    Patent Document 1 discloses a control cable adjustment device 100 shown in FIG. 8a. The adjusting device 100 includes a holder 102 to which an inner cable 101 of a control cable is connected, a rod 104 accommodated in an insertion hole 103 formed in the holder so as to be movable in a longitudinal direction, and an axial direction on an outer periphery of the holder 102. And a slider (lock piece) 105 provided slidably. Further, an eye end 106 is provided at the tip of the rod 104, and a male screw 107 is formed on the outer periphery. The eye end 106 is a part that is rotatably connected to a pin protruding from the shift lever.

  A portion of the holder 102 corresponding to the male screw is formed with a female screw, and the portion where the female screw is formed is divided into two forks, and a deformation having elasticity that expands so as not to sandwich the rod 104 at all times. Part 108. When the slider 105 moves to the tip end side as shown in FIG. 8b, the deforming portion 108 is closed, and the internal thread of the inner surface meshes with the external thread 107 of the rod 104 to restrain the movement of the rod in the axial direction.

  In the assembly process of connecting the inner cable 101 and the rod 104, the slider 105 is first moved to the proximal end side as shown in FIG. 8A so that the holder 102 and the rod 104 are relatively movable. In this state, the eye end 106 is connected to the partner pin. Next, the positions of the holder 102 and the rod 104 are adjusted so that the inner cord 101 is not slack and an appropriate tension is applied. Then, the slider 105 is moved to the tip side at an appropriate position, and the relative movement of the holder 102 and the rod 104 is restrained. Thereby, an appropriate tension and free length of the inner cable 101 are ensured.

  Patent Document 2 discloses a control cable coupling device 110 shown in FIGS. 9a and 9b. The coupling device 110 includes a rod 111 connected to the inner cable and a housing 112 connected to the rod. The base end portion (cable connection side) of the housing 112 is connected to the rod 111 so as to be adjustable in position, and an eye end 114 that is rotatably connected to the pin 113 is integrally provided at the free end. Reference numeral 115 denotes a clip for preventing the pin 113 from coming off.

  As shown in FIG. 9b, the housing 112 is provided with a lock member (lock piece) 116 that prohibits the movement of the rod 111 when pushed in the direction of the arrow P1 and is movable when pulled out in the direction of the arrow P2. Yes. Reference numeral 117 denotes a lock lever (slider) for restraining the lock member in a pushed state. 9a and 9b also connects the eye end 114 to the pin 113, adjusts the length of the inner cable cable, and finally pushes the lock member 116 to operate the lock lever 117.

  When the inner cable of the control cable is connected to a pin or the like using the conventional adjusting device or coupling device, the eye end and the pin are first connected in the unlocked state, and then the length of the inner cable is adjusted. At that time, while holding the holder (housing) with one hand, the rods 104 and 111 are moved in the axial direction with the other hand. In that case, since the rod is movable in the axial direction, it seems that the operation is easy. However, in reality, it is necessary to perform a detailed work of going too far (too long) and returning to the original, and going too far backward (too short) to restore.

  Moreover, even if it is once set at an appropriate position, the housing (holder) and the rod are picked by the finger of one hand and the lock member is operated by the other hand while holding the adjusted position, which is complicated. Especially when the work of connecting the cable is in a place where it is difficult to visually confirm, it is more troublesome because the work is done by groping.

  Moreover, in the said prior art, when the lock member (slider) has stopped in the halfway position, it will be in what is called a half lock state. If this happens when trying to adjust, the holder (housing) cannot or cannot be moved relative to the rod. On the other hand, if the operation is terminated by misunderstanding that the cable is locked, there is a problem that the length changes during use of the cable.

  An object of the present invention is to provide an adjusting device that can easily and quickly adjust the length of a control cable. Furthermore, it is a technical object of the present invention to provide an adjusting device in which a half-lock state is unlikely to occur. Furthermore, this invention makes it a technical subject to provide the control cable with an adjusting apparatus which can adjust the floating length of a cable (inner cable) easily.

Adjustment device of the present invention, the rod and, and a holder which is movably arranged in the longitudinal direction of the rod to one end of the rod, the rod and (or) loose length of cable that is connected to the holder a adjustment device for adjusting the, to the holder, a lock piece which is movable between a locked position to restrain the unlocked position without restraining the relative movement of the holder the rod, the said rod holder is interposed between a resistor biasing means for urging always one direction of the holder along the axial direction of the rod, is interposed between the holder and the locking piece, at least the lock piece a return biasing means for biasing the lock piece in the unlocking position side in front coming to the locked position, when the lock piece comes into the locked position And a first stopper for the lock piece is constrained to not return to the unlocked position side, the return biasing means, the locking piece and the slider provided movably, the slider relative to the holder and a spring element for biasing the side, between the slider and the locking piece, when pressing the locking piece in the locked position, to retract the said slider, said locking piece comes into the locked position a cam mechanism to restrain the lock piece in that position is characterized by being interposed when.

In such adjustment devices, which urges the holder in a direction to exit from the end portion of the rod, which the holder is further provided with a second stopper for stopping to prevent escape from the rod are preferred. Conversely, it may be one that urges in a direction opposite to said biasing means and the distal end of the holder.

A protrusion is provided on the lock piece, a taper surface is formed on a lower surface of the protrusion, and a taper surface that slides on the taper surface of the protrusion is formed on the upper surface of the slider. when pushing the piece to the locking position side, the tapered surface of the slider by the tapered surface of the projection is pushed, that the slider is retracted is preferred.

Moreover, those the slider by the force of the spring element when the lock piece comes in the locked position is disposed on the upper surface of the projection are preferred.

Further, the first stopper for constrained to not return the lock piece is engaged pawl provided at the lower end of the lock piece, when the lock piece came to the locked position, the engagement claw said holder It is preferable to engage with the lower surface.

The return biasing means, extends out from a portion of the locking piece, along with up to the lock piece comes in the locked position urges the locking piece in the unlocked position side in contact with the rod, the lock piece There what tip further comprises a leaf spring engaged with said rod for restraining the return of the lock piece when it came to the locked position is preferred.

  The control cable with an adjusting device according to the present invention includes any one of the adjusting devices, a flexible cable connected to a rod of the adjusting device, and a flexible conduit for guiding the cable slidably. It is characterized by consisting of.

In the adjusting device of the present invention, when the holder is held, the rod is urged in one direction. Therefore, the user can search for an appropriate position while pushing the rod in the other direction against the biasing force. The same applies when the holder is operated while holding the rod. Therefore, it is only necessary to always move in one direction with respect to an appropriate position, and the complicated work of going back and forth as in the prior art is unnecessary.
Further, since a return biasing means for biasing the lock piece to the unlock position side is interposed between the holder and the lock piece at least before the lock piece reaches the lock position, a half-lock state does not occur. . When the lock piece is operated to the lock position, the stopper restrains the lock piece, so that it does not return to the unlock position. Furthermore, since the lock piece needs to be operated to the lock position against the urging force of the return urging means, a click feeling is generated in the lock operation. For this reason, it can be seen that the person to be operated has come to the lock position with a click feeling even in the groping work state.
Further, the slider, the spring element, and the cam means serve as the return biasing means and the first stopper. That is, until the lock piece comes to the lock position, the slider biased by the spring element biases the lock means to the unlock position side. When the lock position is reached, the slider biased by the spring element restrains the lock piece. Since the return biasing means also serves as the stopper means in this way, the number of parts is small and assembly is easy.

The resistance biasing means is intended that biases exiting the holder from the end of the rod, adjust the holder is provided with a second stopper for stopping to prevent escape from the rod device, natural state And the cable's idle length is the longest. Therefore, the operation of adjusting the length is only required to move in the direction of shortening the cable idle length against the biasing force of the biasing member. Even if the resistance urging means urges the holder in the direction opposite to the tip of the rod, the same effect can be obtained. In that case, a stopper for preventing the removal is unnecessary. Further, when adjusting after attaching the holder or rod to the mating member, it is only necessary to operate the holder or rod so that the slack of the cable is eliminated.

The return biasing means, extends out from a portion of the locking piece, along with up to the lock piece comes in the locked position urges the locking piece in the unlocked position side in contact with the rod, the lock piece If is the tip when it came to the locked position is a leaf spring for restraining the return of the lock piece engages with the rod also serves as a and the stopper the plate spring return biasing means. Therefore, the number of parts is small and assembly is easy.

  Since the control cable with an adjusting device of the present invention includes the above-described adjusting device, it is easy to attach the control cable and adjust the free length of the cable.

It is a top view which shows other embodiment.

  1 and 2 includes a rod 11, a holder 12 attached to one end of the rod so as to be movable in the length direction of the rod, and a direction perpendicular to the axial direction with respect to the holder. The lock piece 13 is provided so as to freely move in and out, and the slider 14 is provided on the holder 12 so as to be movable in the axial direction.

As shown in FIG. 4, the rod 11 has a shaft 16 and a large-diameter portion 17 provided near the tip, and a male screw 18 is formed on the outer periphery of the large-diameter portion. The male screw is a portion that engages with the lock piece 13, and an annular groove row or an annular protrusion row arranged continuously can be used instead of the male screw. A spring receiver 19 also serving as a second stopper is attached to the tip of the rod 11 with a screw or an E-ring (retaining ring).

  A hole 21 for inserting the cable 20 is formed on the proximal end side of the rod 11 (see FIG. 7). The cable 20 is an inner rope of a push-pull control cable, for example, and has flexibility. The cable 20 constitutes a control cable together with a flexible conduit 22 that guides the cable 20 in a slidable manner. The shaft 16 of the rod 11 is made of a conventionally known metal. The large diameter portion 17 can be formed by insert molding a synthetic resin at the tip of the shaft 16. However, the whole may be integrally formed from synthetic resin or metal, or may be combined after being formed separately.

  The holder 12 includes a box-shaped or frame-shaped guide portion 23, an eye end 24 extending toward the distal end side thereof, and a slider holding portion 25 extending toward the proximal end side. As shown in FIGS. 2 and 4, the guide portion 23 includes a cavity 26 having a substantially rectangular cross section for guiding the lock piece 13 slidably up and down. On the left and right inner walls of the cavity, guide protrusions 27 projecting from the upper end of the guide portion 23 to the middle.

As shown in FIG. 3, engaging recesses 28 are formed in the lower portions of the left and right inner walls. The engaging recess 28 does not extend to the lower end and stops halfway. The upper end of the engagement recess 28 is an engagement step portion 29, which is a portion where the engagement claw 31 of the lock piece 13 is engaged together with the lower surface 30 of the guide portion 23. That is, the engagement step portion 29 functions as a retaining member for preventing the lock piece 13 from falling off the guide portion 23. The lower surface 30 acts as a ( first) stopper that keeps the lock piece 13 in a locked state (see FIG. 6). The step 28a at the lower end of the engagement recess 28 is tapered so that the engagement claw 31 can easily pass through.

  As shown in FIG. 2, concave portions 32 are respectively formed at the upper ends of the front and rear walls of the guide portion 23. These recesses 32 are portions that receive the protrusions 33 protruding from the upper ends of the front and rear surfaces of the lock piece 13 when in the locked state. A through hole 34 for passing the large diameter portion 17 of the rod 11 is formed in the front and rear walls.

  The eye end 24 has a plate shape, and a fitting hole 35 for fitting a pin provided on the shift lever is provided at the tip as shown in FIG. A bush 35 a is fitted in the fitting hole 35. Further, an opening 36 penetrating in the vertical direction is formed on the base end side of the eye end 24. The other end of the through hole 34 of the guide portion 23 is open to the opening 36. A spring accommodating hole 38 for accommodating the distal end portion of the first spring 37 is formed on the inner surface of the opening portion 36 on the distal end side. The first spring 37 is a compression coil spring in this embodiment.

  The distal end side of the first spring 37 is accommodated in the spring accommodating hole 38, and the other end is fitted around the protrusion 19 a of the spring receiver 19 fixed to the distal end of the rod 11. As a result, the holder 12 is always urged forward with respect to the rod 11 (rightward in FIG. 1). In other words, the cable is biased in the direction of increasing the cable free length.

  The slider holding portion 25 protruding from the rear end of the guide portion 23 has a substantially cylindrical shape, and its internal cavity 25a communicates with a through-hole 34 on the wall on the back side of the guide portion 23, and the rod 11 has a shaft. Fits slidable in the direction. A plate-like support piece 39 projects upward on the upper surface of the rear end of the slider holding portion 25, and a plate-like slider guide 40 extends from the front surface of the support piece 39. A substantially rectangular parallelepiped slider 14 is slidably fitted to the slider guide 40.

  A hole 41 having a rectangular cross section for inserting the slider guide 40 is formed on the rear surface of the slider 14 (see FIG. 4). Tapered surfaces 42 and 43 are formed on the upper and lower surfaces of the front end of the slider 14, respectively. In this embodiment, the upper tapered surface 42 is larger than the lower tapered surface 43. A second spring 44 is interposed between the rear end of the slider 14 and the support piece 39. The second spring 44 is a compression coil spring and is mounted so as to surround the slider guide 40. Thereby, the slider 14 is always urged forward.

  As shown in FIG. 4, the lock piece 13 has a substantially rectangular parallelepiped appearance, and a substantially U-shaped groove 46 extending forward and backward is formed on the lower surface side. Therefore, the entire lock piece 13 has an inverted U shape. A female screw 47 that engages with the male screw 18 of the rod 11 is formed on the bottom surface (curved surface) of the groove 46 (see FIG. 3). A protrusion 49 is provided on the upper surface of the lock piece 13 for pressing with a finger. A slit 50 that opens toward the lower surface is formed on the front and rear sides of the side surface of the lock piece 11. Thereby, the front and rear portions of the slit 50 are flexible pieces 51 that can be flexibly bent in the direction of arrow P in FIG.

  Furthermore, in this embodiment, the leaf spring 52 protrudes upward from the inner surface side of the lower end of the flexible piece 51. The leaf spring 52 extends somewhat upward and then extends obliquely inward. The length of the leaf spring 52 is such that when the lock piece 13 is in the unlocked position in FIG. 3, the upper and lower surfaces of the leaf spring 52 are in contact with the upper surface side of the large-diameter portion 17 of the rod 11 and are in the locked position in FIG. At this time, the free end of the leaf spring 52 has a length that engages with the lower surface side of the large diameter portion 17.

  The protrusion 33 described above is provided near the upper end of the front and rear surfaces of the lock piece 13. The front and lower surfaces of the front and rear projections 33 are a lower taper surface 53 that slides in contact with the upper taper surface 42 of the slider 14, and the upper surface of the tip is a small lower taper surface 43 of the slider 14. And an upper tapered surface 54 that slides in contact therewith. The lower taper surface 53 of the protrusion 33 is larger than the upper taper surface 54. The large tapered surfaces 42 and 53 are an embodiment of the cam mechanism in the claims. The front and rear protrusions 33 and 33 also act as a knob when the lock piece 13 is extracted from the holder 12.

  The holder 12, the lock piece 13, and the slider 14 are made of synthetic resin. However, other materials such as metal can be used. In addition, in said embodiment, although the holder 12 and the lock piece 13 are each shown as an integral thing, it can also comprise combining the several member which consists of the same material or a different material.

Next, the operation of the adjusting device 10 configured as described above will be described with reference to FIGS. 2, 3, 5, and 6.
[Unlocked state]
2 and 3 show the unlocking state of the adjusting device 10. In this state, the upper portion of the lock piece 13 protrudes from the holder 12, and the female screw 47 on the inner surface is not engaged with the male screw 18 of the rod 11. Therefore, the holder 12 moves in the direction of increasing the cable idle length by the urging force of the first spring 37, and the spring receiver 19 comes into contact with the holder 12 and stops.

  The inner surface of the leaf spring 52 of the lock piece 13 is in contact with the upper portion of the large-diameter portion of the rod 11 and is bent somewhat outward. Therefore, the lock piece 13 is biased upward, and the engagement claw 31 is engaged with the engagement step portion 29. As a result, the lock piece 13 is stably held in the unlocked state and does not fly upward. The slider 14 is urged by the second spring 44, and the tip thereof is in contact with the rear surface of the lock piece 13.

[Half lock prevention]
Since the lock piece 13 is urged upward by the leaf spring 52 as described above, it is difficult to move to the holder 12 side by mistake and enter into a half-lock state in which the male screw 18 and the female screw 47 are somewhat engaged. Even if the lock piece 13 is pushed in by some amount, the projection 33 on the rear side of the lock piece 13 comes into contact with the slider 14, so that half-locking is also prevented in this portion.

[Locked state]
In order to lock the adjusting device 10 in this state, the protruding portion 49 of the lock piece 13 is pushed in the direction of the arrow S1 in FIG. 2 against the urging force of the leaf spring 52. At that time, the large tapered surface 53 on the lower end surface of the rear projection 33 abuts on the cam surface 42 on the upper end surface of the slider 14. As a result, the lock piece 13 receives a biasing force of the second spring 44 via the slider 17 and is biased upward. For this reason, the user will deliberately push hard. When the lock piece 13 is further pushed in, the protrusion 33 moves over the tip of the slider 14 and moves downward. Therefore, the user knows that the work is surely performed by the click feeling at that time. Thereafter, as shown in FIG. 5, the slider 14 moves forward until it abuts against the rear surface of the protruding portion 49 and presses the upper surface of the lock piece 13. Thereby, the lock piece 13 is restrained in the lock position.

  On the other hand, as can be seen from FIG. 3, the leaf spring 52 of the lock piece 13 bends outward as the lock piece is pushed. When further pushed in, the lower end of the flexible piece 51 separated by the slit 50 comes into contact with the step portion 28a of the engaging recess 28 and bends inward, and then the engaging claw 31 moves downward along the inner surface of the holder 12. . Then, when the engaging claw 31 comes below the lower surface 30 of the holder 12, it engages with the lower surface 30 as shown in FIG. Thereby, the locked state is maintained more safely. Further, in this state, the distal ends of the left and right leaf springs 52 come to the lower surface side of the rod 11 and the distal ends engage upward, so that the locked state is more reliably ensured.

  The adjusting device 10 is used for, for example, a push-pull control cable for connecting a transmission and a shift lever of an automobile, particularly a select cable. In that case, the other end side of the inner cable (reference numeral 20 in FIG. 7) is first attached to the transmission side by the cable end fixing device, and the eye end 24 of the holder 12 is attached to the pin of the shift lever. At that time, the inner cable is pushed to the transmission side by the urging force of the first spring 37, so that it is somewhat loosened. Next, the rod 11 is pushed into the holder 12 against the urging force of the first spring 37 to set an appropriate idle length. In that case, it is only necessary to move from one direction against the urging force of the first spring 37, so there is no useless operation such as going back and forth as in the case of free, and the setting is easy.

  And the lock piece 13 is pushed in in an appropriate position, and the positional relationship of the axial direction of the rod 11 and the holder 12 is locked. In the pushing operation, a click feeling based on the cam action with the slider 14 is obtained as described above, so that the user can easily understand that the lock has been performed. In particular, when the adjustment operation is performed in a groping state where the lock piece cannot be seen, the operation becomes easier, the operation can be surely performed until the lock state is reached, and the trouble of leaving the half-lock state is reduced. Once in the locked state, the distal end of the leaf spring 52 engages with the lower surface side of the rod 11 and the slider 14 presses the upper surface of the lock piece 13, so that the locked state is safely maintained.

  When it is desired to release the lock for maintenance or the like, the slider 14 is retracted to release the engagement with the upper end of the lock piece 13, and the tip of the leaf spring 53 is further expanded to release the engagement with the rod 11. Then, the lock piece 13 is pulled upward. This returns to the unlocked state of FIG.

  In the above embodiment, the rod 11 and the holder 12 are urged in the direction of extending the cable's idle length, but conversely, the rod 11 and the holder 12 may be urged in the direction of reducing the idle length. In such a structure, for example, as shown in FIG. 7, the tip end side of the rod 11 is extended, and a first spring 37 made of a compression coil spring is interposed between the spring receiver 19 and the wall on the rear side of the opening 36. Can be realized. 1 can be realized by using a tension coil spring or the like instead of the compression coil spring.

  In the above-described embodiment, the protrusion 33 hits the slider 14 after the lock piece 13 is pushed down somewhat (see FIG. 2), but it can also be configured to hit the slider from the beginning in the unlock position. In that case, the second spring 44 urges the lock piece 13 upward through the slider 14 in the unlocked state due to the cam action of the upper tapered surface 42 of the slider 14 and the lower tapered surface 53 of the protrusion 33. Further, half-lock can be further prevented.

  Moreover, in the said embodiment, although the locked state is restrained by both the slider 14 and the leaf | plate spring 52, depending on the case, only one side may be sufficient. When the slider 14 is used and the leaf spring 52 is omitted, the structure of the lock piece can be simplified while maintaining the click feeling, and the molding becomes easy. Conversely, when a leaf spring is employed and the slider is omitted, the number of parts can be reduced.

  As described above, the means for biasing the lock piece 13 in the direction of projecting from the holder 12 can be configured by the second spring 44 via the slider 14 or the leaf spring 52 via the rod 11. However, it can be directly urged by interposing a compression coil spring or the like between the lock piece 13 and the holder 12. Moreover, in the said embodiment, although the cable 20 is connected with the rod 11, you may connect with the holder 12 side. Although the cable 20 and the conduit 22 in FIG. 7 constitute a push-pull control cable having the cable 20 as an inner cable, a pipe may be used in place of the conduit 22. It can also be a pull control cable.
