点があつた。 Generally, a wire made of stranded metal wire undergoes permanent elongation (irreversible elongation, simply referred to as elongation) due to the load applied to it. This growth is particularly large in the early stages of use. This elongation of the wire causes play in the operation of the drive device and in the following of the driven device, making it impossible to accurately follow the driven device. In order to absorb such elongation of the wire, conventional transmission devices connect a wire length adjustment member in the form of a bolt and nut to the end of the wire or at an arbitrary position, and the elongation of the wire is adjusted by threading the bolt in and out. Some methods are used to remove the stretch of the wire, or attach a tension pulley and move the tension pulley to remove the stretch of the wire. must be carried out,
Further, the work is extremely troublesome, and furthermore, depending on the location where the transmission device is installed, adjustment is not easy.

向に回転する。 One embodiment of a transmission device that can employ the mechanism of the present invention is composed of a driving device 1, a driven device 2, and a wire inserted into a conduit 9 to connect them, as shown in FIG. When the lever 5 of the drive device 1 is rotated in the direction a, the first pulley 6 and the second pulley 12 are also rotated in the direction a, and one end 41 of the wire 4, which is locked to both pulleys, is connected to the casing 10. , and the other end 42 is sent out, so that the pulley 7 of the driven device 2, around which the wire is wound (or locked in a suitable position), rotates in the J direction and rotates around the shaft. 8 also rotates in the J direction.

不安定となることは避けうべくもない。 By the way, if the load applied to the shaft 8 is large, the wire 4 will stretch, and this stretch will cause play in the rotation of the shaft 8 when the lever 5 is operated. Not only does the shaft 8 not follow accurately, but even when the lever 5 is stopped, the shaft 8
It is unavoidable that the motor rotates somewhat in the J or K direction and the operation of the driven equipment becomes unstable.

はワイヤの伸びは吸収されない。 In FIG. 5, when the lever 5 is rotated in the direction a, the first pulley 6 is rotated in the direction a by the shaft 11, and at the same time the second pulley 6, which has second ratchet teeth meshing with the first ratchet teeth 6a, also rotates. One end portion 41 of the wire, which rotates together in the direction a, is connected to the second end portion 41 of the wire.
The wire 4 wound around the pulley 12 slides in the e direction, passes through the pulley 7, and at the same time, the other end 42 of the wire is sent out from the first pulley 6, and the wire 4 slides in the d direction. Thus, the driven device 2 By rotating the pulley 7 in the J direction and rotating the shaft 8 in the J direction, the driven device can be remotely controlled. At this time, the elongation of the wire is not absorbed.

If the wire 4 is sufficiently tensioned and not slack, the wire 4 slides in the C direction and the pulley 7 of the driven device 2 is rotated in the K direction, and the other end 41 of the wire is shown in FIG. The end 41 of the wire is pulled in the f direction and is unwound and sent out from the second pulley. In this case, the ratchet teeth rotate in the idling direction, but the second pulley is pressed against the first pulley by the elastic member 13. Therefore, as mentioned above, wire 4
When the tension is sufficient, the torque applied to the second pulley winds the wire around the second pulley, pulls out the wire from the first pulley, rotates the pulley 7 of the driven device in the K direction, and becomes the driven device. Remotely control equipment (not shown).

始める。このようにして再び従来と同様に正確に
従動装置を作動させることができる。 In the device of this embodiment, if the wire stretches, the stretch is absorbed by rotating the lever 5 in the direction b. That is, in FIG. 4, when the lever 5 is rotated in the direction b and one end 42 of the wire is wound around the first pulley in the direction b, the pulley 7 of the driven device 2 is loosened if the wire 4 stretches. Since the other end 41 (Fig. 5) of the wire 4 that has passed through is not immediately pulled in the f direction, the second pulley to which the wire 4 is locked does not rotate in the b direction and is in a stopped state.In this case, the ratchet is The wire spins idly and only the first pulley rotates in the direction b, winding the wire and absorbing the elongation. When the elongation absorption is completed, the wire 4 no longer has any slack and is fully tensioned, so the second pulley is pulled in the direction b. As a result, due to the pressure of the elastic member 13, it becomes integrated with the first pulley again and starts rotating in the same direction. In this way, the driven device can again be operated accurately as before.

れた効果もある。 In this way, the mechanism of the present invention has the effect of constantly absorbing the elongation of the wire while remotely controlling the driven device using the drive device.At the same time, conventional devices of this type have the effect of adjusting the tension to give the wire an appropriate tension when assembling it. However, in the case of a device using the mechanism of the present application, if the wires are wound around each pulley in advance when assembling, the wires can be automatically assembled by simply rotating the lever 5 in the direction b. A predetermined tension is obtained. That is, when the lever 5 is rotated in the b direction, only the first pulley idles and winds up the wire, and when a predetermined tension is obtained, the second pulley also becomes integral with the first pulley and starts rotating in the b direction. As described above, there is also the excellent effect that the desired tension can be obtained extremely easily compared to the conventional method.

も有する。 Next, a spiral spring (hereinafter simply referred to as a spring) is installed in the space 12b provided in the second pulley of the present mechanism.
14, and locks one end to the second pulley 12 and the other end to the casing 10 to connect the second ratchet 12a.
By mounting the second pulley so as to urge it in the direction in which the lever 5 idles (direction a), the second pulley is rotated in the direction a by the spring 14 in the process of rotating the lever 5 in the direction b and absorbing the elongation of the wire. Since it is biased, it acts as a brake until a certain tension is obtained, which has the effect of absorbing the elongation of the wire even more accurately. Furthermore, the mechanism of the present invention can be used in devices where the operating force varies depending on the direction of operation, such as an automobile window regulator, in other words, when the operating force is increased due to the weight of the glass, it is heavy.
If it is attached to a device that becomes lighter when lowering, it should be installed so that the spring 14 or the spring will be caught when the operating force is light (when lowering the glass), and vice versa when the operation is heavy (when raising the glass). Since it also functions as a balance spring that can be operated with a relatively light operating force due to the return biasing force of the wound spring 14, it has the excellent effect of achieving smooth operation with little difference in operating force between the two operations. .

可能である。 Generally, as mentioned above, the elongation of a wire is larger at the initial stage and occurs over a relatively long period of time, and the longer the wire, the greater the elongation, and conventional types of adjustment (e.g., tension pulley type) have a limit to the amount of elongation that can be absorbed. However, in the mechanism of the present invention, since the ratchet teeth are provided all around the side of the pulley, even slight elongation can be absorbed, and the amount of elongation absorbed is extremely large due to the structure and can be absorbed automatically. is possible.

Furthermore, in the above-mentioned embodiment, a case was explained in which a transmission device is operated by using one wire and winding approximately the middle of the wire around the driven side pulley 7, but using two wires and winding approximately the middle of the wire around the pulley 7 on the driven side. The portion may be locked and wound around each pulley on the drive device side.
