Description

[Detailed description of the invention] [Field of industrial application] This invention selectively transmits the operating force of the handle to one of two driven devices by pushing and pulling the inner cable by operating the handle. This invention relates to a push-pull cable transmission force extraction device.

[Conventional technology]

This type of cable is used in the opener mechanism for automobile fuel filler doors and trunk doors, known as Special Publication No. 58-24585. Figure 8 shows opener mechanisms A and B for the fuel inlet door 1 and trunk door 2 of a conventional automobile.
This shows that. In the figure, reference numeral 3 denotes an operating handle swingably installed on the vehicle body 4 on the driver's seat side of the automobile. An inner cable 5 is connected to the lower end side of the operating handle 3. The other end of the inner cable 5 is connected to a lever type lock member 6 of the opener mechanism B.

Further, an intermediate stopper 7 is provided in the middle of the cable 5, as shown in FIG. 8 is an outer casing that covers the inner cable 5 between the operating handle 3 and the intermediate locking device 7. The end 8 of this cable 8 on the operation handle 3 side
A is connected and fixed to a bracket 9 fixed to the vehicle body 4 with bolts or the like. Further, the end portion 8b on the side of the intermediate locking tool 7 is connected to the locking member 10 of the opener mechanism A.
is connected and fixed via a connecting rod 11 to a swing lever 12 which is operated to an unlocked state. The lock member 10 consists of a holder main body 10a disposed toward the inside of the vehicle body and a lid body 1 disposed toward the fuel inlet installation chamber.
It is slidably inserted into the inside of 0b. The holder main body 10 and the lid body 10b are screwed together and fixed to the side wall of the fuel inlet installation chamber.

Reference numeral 13 denotes an outer casing that covers the inner cable 5 between the intermediate locking device 7 and the locking member 6 of the opener mechanism B. An end 13a of the outer casing 13 on the side of the intermediate stopper 7 is connected and fixed to a base plate 14 fixed to a part of the vehicle body. Further, this end portion 13a has a cavity portion 16 for sliding of the intermediate locking member 7. Intermediate locking tool 7
is the ninth position when the operating handle 3 is in the neutral position.
As shown in the figure, it is locked at the end of the cavity 16. An end 13b of the outer casing 13 on the lock member 6 side is connected and fixed to a bracket 15 fixed to a part of the vehicle body. Above swing lever 1
2 is swingably fixed to the substrate 14 at its intermediate portion. 18 and 19 are lock members 10 and 6
This is a return spring.

Next, the operating procedure of the conventional transmission force extraction device 17 having the above configuration will be explained. First, the case where the operating handle 3 is operated in the push direction D from the neutral position shown in FIG. 8 will be described. In this case, the inner cable 5 is prevented from moving to the right in the figure by the intermediate stopper 7. Therefore, the outer casing 8 moves in the direction d in the figure as a reaction force. As a result, the swing lever 12 swings about the pivot portion 12a in the counterclockwise direction in the figure, and the opener mechanism A is opened via the connecting rod 11.
The locking member 10 is brought into an unlocked state. On the other hand, when the operating handle 3 is operated from the neutral position in the pull direction E, the inner cable 5 moves in the direction e in FIG. 8, so the lock member 6 of the opener mechanism B is swung clockwise in the figure. become,
Make this unlocked. In this case, the intermediate stopper 7 moves in the left direction d in FIG. 9 within the cavity 16. In this way, the conventional transmission force extraction device 1
Reference numeral 7 is for placing the opener mechanisms A and B into a locked state or an unlocked state.

[Problem that the invention attempts to solve]

However, when the conventional device 17 is assembled, the opener mechanism A and the board 14 are
The lock member 10 and the swing lever 12 of the opener mechanism A must be installed separately from the connecting rod 11.
I had to connect it via . Therefore, the number of parts is large, which causes an increase in costs, and the assembly work is also very troublesome. Also, the connecting rod 11
This means that the operating force is not transmitted smoothly from the swing lever 12 to the locking member 10, and as a result, the operating feeling is not necessarily good. Furthermore, due to the large number of parts, a strong assembly cannot be achieved.

In addition, the locking member 10 is attached by screws, and push/pull cables are normally routed along the body with the chassis and body assembled.
However, the holder main body 10a and the lid body 10b are located inside and outside the body, and at least two workers are required. This has been an obstacle to the policy of the automobile industry, which is promoting unmanned vehicles.

Therefore, Utility Application No. 156382 (1982)
63658), a lock member 10 has been developed in which only the locking piece is cut and raised at the tip of the holder and expanded to be attached to the side wall of the fuel inlet installation chamber (not shown). ). However,
In this case, the cut-and-raised locking piece is likely to become fatigued due to complex and intense vibrations of the vehicle body, and in some cases, there is a risk that it may break and lose its function as an opener mechanism.

The present invention has been developed to improve and eliminate the above-mentioned drawbacks of the conventional device, and aims to reduce the number of parts, simplify the assembly work, and further improve the assembly strength.

[Means for solving problems]

The means for solving the above problems of the present invention are as follows:
An operating handle connected to one end of an inner cable covered with an outer casing, a first driven device connected to the middle of the inner cable, and a second driven device connected to the other end of the inner cable. By moving the operating handle from the neutral position in opposite directions, the intermediate locking device, swing lever, etc. provided in the middle of the inner cable are operated, and the first driven device or the first driven device is operated. In a device that selectively operates two driven devices, one of the driven devices includes a cylindrical holder made of synthetic resin that fits and holds a lock member so that it can move forward and backward, and a nut member that fixes the holder to the vehicle body. A box-shaped part with a small width dimension is formed at the tip of the holder, and a threaded part is carved on the outer peripheral surface of the box-shaped part along the axial direction of the holder but discontinuous in the circumferential direction. , a cut-and-raised locking piece that has a width larger than the diameter of the threaded portion on at least one pair of opposing non-threaded surfaces on the outer circumferential surface of the box-shaped portion and is retractable by pressing is provided on the distal end side of the holder. The holder is formed to expand toward the base end side, and the tip of the holder is inserted into the vehicle body opening, and the cut and raised locking piece is engaged with the vehicle body opening to fit and attach to the vehicle body. The nut member is fixed to the vehicle body by being screwed into the threaded portion.

[Effect]

As shown in FIGS. 1 to 7, the holder 31 of the locking member 27 of the first driven device is molded from synthetic resin, and a locking piece 43 is cut and raised on the outer peripheral surface of the tip.
43, when arranging the cable, the tip of the holder can be simply inserted into the opening 48 of the side wall (part of the vehicle body) 45 of the fuel inlet 46, and the cut and raised locking pieces 43, 43 can be elastically connected. After contracting, it expands and returns to grip the fuel inlet side wall 45. In other words, the installation work can be carried out by one person from inside the vehicle body.

Furthermore, upon completion of the assembly of the vehicle body, the holder 31 can be firmly attached by simply screwing the nut member 51 from the fuel inlet installation chamber 46 side onto the threaded portion 50 carved at the tip of the holder. Moreover, the holder 31 is made of synthetic resin,
While forming the threaded portion 50 discontinuously in the circumferential direction,
The width dimension of the non-threaded surface 52 is set smaller than the diameter of the threaded portion 50. (Otherwise, it is impossible to thread the nut member 51 together.) Therefore, there is a slight gap between the nut member 51 and the non-threaded surface 52. Furthermore, since the cut and raised locking pieces 43 are formed on the non-threaded surface 52, the rigidity of the box-shaped portion 39 in the circumferential direction is slightly reduced. With these configurations, even if the nut member 51 screwed into the threaded portion 50 of the box-shaped portion 39 is tightened excessively, the threaded portion 5
0 bends inward, while the non-threaded surface 52 elastically deforms to escape into the gap with the nut member 50, so there is no risk of crushing the thread. Further, since the cut-and-raised locking piece 43 formed to prevent the holder 31 from coming off shrinks and deforms when the nut member 51 is screwed, the nut member 51
A pressing force is applied to the inner circumferential surface of the nut member 51 to prevent loosening of the nut member 51.

〔Example〕

The configuration of the present invention will be explained below based on the embodiments shown in the drawings. It should be noted that the same reference numerals as in the conventional case indicate the same members. The first driven device is a fuel inlet opener mechanism, and the second driven device is a trunk lid opener mechanism.

FIG. 1 is a diagram schematically showing the entire transmission force extraction device 20 according to the present invention. As shown in the figure, the substrate 21 of this embodiment has bent pieces 22 and 23 at both ends.
, and a portion 26 extending from the portion 25 in a direction substantially perpendicular to the portion 25 . The above part 25 has an opener mechanism A (see Fig. 8).
A locking member 27 is attached. The locking member 27 has a long hole 28 on the side surface of the approximately central portion.
Flanges 29 and 30 are provided at both ends thereof. In addition, a holder 3 is provided on the tip side of the lock member 27.
1 is fitted on the outside. This holder 31 is made of synthetic resin material and is constructed as shown in FIGS. 6 and 7. That is, the holder 31 holds the cylindrical body 3
8 and a box-shaped part 39 provided on the distal end side of the cylindrical part 38, and a locking member 27 at the center in the axial direction.
A through hole 40 for insertion is provided. Box-shaped part 3
The through hole 40 of No. 9 has a rectangular cross section. Cylindrical part 3
Flanges 41 and 42 are provided on the outer peripheral surface of the board 21 to sandwich the bent piece 22 of the board 21, and a part of the flanges 41 and 42 are provided on a pair of opposing non-threaded surfaces 52 of the box-shaped portion 39. Cut and raised locking pieces 43, 43, which have a certain degree of self-elasticity, are formed in an enlarged manner.
Additionally, threaded portions 50 are discontinuously carved in the circumferential direction on the outer periphery of the box-shaped portion 39, so that a nut 51 can be screwed onto the threaded portions 50. In addition, in the same figure, 4
4 is a sealing member.

The distal end side of the locking member 27 is connected to the bent piece 2 through the flanges 41 and 42 of the holder 31.
2, and the rear end side is inserted into the fitting hole 33 of the bent piece 23. and,
A spring 34 is externally fitted between the bent piece 23 and the flange 30, and constantly urges the lock member 27 to the left in FIG. Reference numeral 35 denotes a bent piece erected on the extended portion 26. This bent piece 35 has an end portion 13a of the outer casing 13.
are connected and fixed. Reference numeral 36 denotes a swinging lever whose intermediate portion is swingably attached to the extension portion 26 and intersects with it. One end of the swing lever 36 is inserted into the elongated hole 28 of the lock member 27. Further, a bent piece 37 for attaching the end portion 8b of the outer casing 8 is provided upright on the other end side. The other configurations are the same as in the conventional case.

In short, in the device 20 of this embodiment,
The base plate 21, the lock member 27, and the swing lever 36 are integrally attached. In addition, a threaded portion 50 and raised locking pieces 43 are formed on the outer peripheral surface of the tip of the holder 31. Therefore, the assembly of these members to the vehicle body 45 can be done by one person by first performing a single fitting operation during wiring, and then fitting and fixing each member to the side wall of the installation chamber 47 at the same time. Also, during final assembly, remove the nut 5 from the installation chamber 47 side.
By screwing 1, it can be firmly fixed and can cope with complex and severe vibrations of the vehicle body.

This will be explained in more detail with reference to FIGS. 1, 6 and 7. Each of the above members 21, 27,
36 is installed by providing an opening 48 in a part of the vehicle body 45 constituting the installation chamber 47 of the fuel inlet 46, and inserting the box-shaped portion 39 of the holder 31 into the opening 48 as indicated by the arrow h in FIG. Just fit it in from the direction (inside the vehicle body). In this case, the opening 48 is slightly larger than the height and width W of the box-shaped portion 39 (the height and width are the same in the case shown), and larger than the width L between the cut and raised locking pieces 43, 43. is also set small. Therefore, when the locking pieces 43, 43 are fitted, they shrink and deform due to their own elasticity, pass through the opening 48, and then expand and return to their original position to prevent them from coming off. For this reason, a part of the vehicle body 45 is
and the flange 41. That is, the board 21, the lock member 27, and the swing lever 36
can be attached to the vehicle body 45 with a one-touch operation. Moreover, these members 21, 27, 3
6 has an integral structure, so a strong assembly can be obtained. Furthermore, the number of parts is smaller than that of the conventional one shown in FIG. 8, and costs can be reduced.

In addition, during final assembly, a threaded portion 5 is cut from the installation chamber 47 of the fuel inlet 46 to the tip of the holder.
0, screw the holder 31, the swinging lever 36 attached to it, and the board 21 onto the vehicle body
Just stick to it. As a result, strong fixation by the nut 51 is obtained, and the holder 31 is attached to the vehicle body 45.
It can withstand even complex and severe vibrations.

Next, the operation mode of the embodiment device 20 configured as described above will be explained. First, the case where the operation handle 3 is operated in the push direction D will be explained. When the handle 3 is operated in the D direction, a pushing force in the f direction is applied to the inner cable 5 as shown in FIG. However, the inner cable 5 is restrained from moving to the right by the intermediate stopper 7. Therefore, the outer casing 8 moves in the d direction as a reaction force, and the swing lever 36 swings clockwise in FIG. 3 about the pivot portion 36a. Follow. The swing lever 36 moves the locking member 27 in the right direction g in FIG. 1 to bring it into the unlocked state. Therefore, it is possible to freely open the fuel inlet door 1. When the operating handle 3 is operated in the pull direction E, the inner cable 5 moves within the cavity 16 from the state shown in FIG. 3 to the position shown in FIG. 5. Therefore, the movement of the inner cable 5 is transmitted to the locking member 6 of the opener mechanism B. The lock member 6 is the pivot joint 6
It begins to swing counterclockwise in FIG. 1 with point a as the center, and is in an unlocked state. In short, the unlocking of each locking member 27 and 6 by the push/pull operation of the operating handle 3 is as follows.
This is the same as the conventional case.

[Effect of idea]

As explained above, in the device of the present invention, a threaded portion and a raised locking piece are formed on the outer circumferential surface of the tip of the holder that fits and holds the locking member of the driven device. Therefore, when arranging the cable, the tip of the holder can be assembled by a single fitting operation from inside the vehicle body. Therefore, it can be done by one person, saving labor. Also, during final assembly, nuts can be tightened from the outside of the vehicle body.
Provides strong fixation. In other words, it is possible to cope with complex and severe vibrations of the vehicle body. Furthermore, even if the nut member screwed into the threaded part of the box-shaped part is over-tightened, the threaded part will flex inward due to its small wall thickness, ensuring proper engagement with the nut member. On the other hand, the non-threaded surface can be elastically deformed to escape into the gap with the nut member, so there is no risk of crushing the thread. Furthermore, since the cut-and-raised locking piece formed to prevent the holder from coming off shrinks and deforms when the nut member is screwed together, a pressing force is applied to the inner circumferential surface of the nut member, causing the nut to tighten. It also has the effect of preventing members from loosening.
