[Detailed description of the invention] This invention was created by the creator of the invention
(Refer to Japanese Utility Model Application No. 56-130901 and Japanese Utility Model Application Publication No. 57-78366, which are divisional applications related to No. 6) This invention relates to improvements in bundle devices.

The automobile window opening/closing bundle device according to the applicant's previous application consists of a base provided at an appropriate position near the driver's seat in the vehicle body, and a control lever rotatably pivoted to the base at one end. One end of the wire is connected to the other end of a push/pull force transmitting wire, which is connected to a window glass rotatably hinged on one side.

That is, as shown in FIG. 1, the end of the outer tube 71 of the push/pull force transmitting inner wire 7 is fixed to the right end of the base standing wall 6.
A long groove 61 having a length corresponding to the pushing and pulling length of the inner wire 7 required for opening and closing a window glass (not shown) is bored in the vertical wall 6.

A pin 8 is slidably fitted into the long groove 61, and the end of the inner wire 7 is fixed to the pin 8.

In order to slide the pin 8 in the long groove 61, a control lever 1 having one end rotatably pivoted is rotatably attached to the base wall 6 at one end.

As shown in FIG. 2, the control lever 1 is formed by making two plates of the same shape face each other with the above-mentioned vertical wall 6 in between.

An elongated hole 11 is suitably drilled in a portion where the control lever 1 covers the elongated groove 61 so as to straddle the elongated groove 61, and the pin 8 is fitted loosely into the elongated hole 11 so as to be able to slide.

A pawl 3 is mounted on the free end side of the control lever 1, and a handle 4 is rotatably mounted on shafts 32 and 4 located above the pawl 3.
1, and a ratchet rack 2 is provided on the upper edge of the base wall 6 in an arc shape centered on the support shaft 13 so as to be able to engage with the pole 3.
is formed.

As is clear from the figure, the pawl 3 is in the form of a strip, and is rotatably attached to a shaft 32 approximately in the center thereof, and a pawl portion that engages with the teeth of the ratchet rack 2 is formed at the right end portion 31 of the pawl 3 .

The handle 4 has a shaft hole 41' approximately in its center as shown in FIG.
A cam 42 is formed at the lower edge of the shaft hole 41', and has a cam surface consisting of a fairly long straight line with an upward slope to the left and an arcuate curved line connected to the straight line at one end. is,
An arm 44 and a handle lever 43 form a substantially U-shape on the upper side.
A projection 45 is formed below the handle lever 43, above the cam 42, and located on the right side of the shaft hole 41'.

Therefore, the handle lever 43, cam 42, and projection 45 are all integrally formed.

As mentioned above, the handle 4 is pivotally attached to the free end side of the control lever 1 above the pawl 3, and as shown in FIGS. It engages with the pawl 3 at the straight portion of the cam 42 surface on the opposite side.

That is, the cam 42 surface of the handle 4 contacts the pole 3 on the left side of the support shaft 32 thereof.

On the other hand, the claw portion 31 is located on the right side of the support shaft portion 32.

The pin 8, the support shaft 32 of the pawl 3, and the support shaft 41 of the handle 4 are supported on both sides by opposing members of the control lever 1 (see FIG. 2).

Reference numeral 12 denotes a stopper, which is formed by bending one plate of the control lever 1 member as shown in FIG. 2, and is engaged with the handle 4.

Reference numeral 5 denotes a tension spring, one end of which is attached to the tip of an arm 44 provided on the handle 4, and the other end attached to the left end 33 of the pawl 3, so that the pawl 3 is rotated clockwise to engage with the ratchet rack 2, and the other end is attached to the left end 33 of the pawl 3. are urged to rotate counterclockwise so as to be brought out of alignment with the pole 3.

The handle 4 is restrained from the rotational bias by the spring 5 as a protrusion 45 formed thereon abuts and engages with the lower edge of the stopper 12 formed on the free end side of the control lever 1. The pawl 3 is brought into contact with the tooth surface 21 of the ratchet rack 2 on the end side of the pawl 31, and is stopped with the pawl 31 meshed with the rack 2.

Therefore, in FIG. 4, when the pawl 3 is in the engaged state with the ratchet rack 2 (see the solid line), the handle lever 4
3 in the clockwise direction, the right end of the cam 4 pushes down the left side of the shaft 32 of the pawl 3 at the cutting edge, so the pawl 3 rotates counterclockwise and the pawl claw 31 is released from engagement with the ratchet rack 2 (see imaginary line).

Then, when the handle lever 43 is continuously rotated clockwise, the lower end of the right side of the handle lever 43 moves to the control lever 1.
(see imaginary diagram), the operating force acting on the handle lever 43 is transmitted to the control lever 1, so the handle 4 is integrated with the control lever 1. and rotate it clockwise.

Therefore, the pin 8 slides to the right in the elongated groove 61 and upward in the elongated hole 11, pushing the wire 7 to the right, and as a result, the window opens.

When the operating force is removed from the handle lever 43, the spring 5
As a result of this action, the protrusion 45 thereof rotates counterclockwise until it engages with the stopper 12, so that the pawl 3 pawl 31 automatically returns to the stopping position where it engages with the ratchet rack 2.

Contrary to the above, the handle lever 43 is in the state shown by the imaginary line in FIG.
When the handle 43 is rotated counterclockwise, the protrusion 45 provided integrally with the handle 43 moves against the stopper 12 in the stopped state.
Since the control lever 1 is fixed to the lower edge of the handle 4, the operating force is transmitted to the control lever 1 as it is. On the other hand, since the pawl 3 and the ratchet rack 2 are not aligned in the counterclockwise direction, the control lever 1 rotates in the counterclockwise direction.

Therefore, the pin 8 slides to the left within the long groove 61 and downward within the long hole 11 to pull back the wire 7, so that the window is closed.

By the way, in the above-mentioned automobile window opening/closing handle device, when the handle lever 43 is in the restrained state as shown in the first figure, the right end side of the pawl 3 is in contact with one tooth-shaped surface 21 of the ratchet rack 2, so that the window cannot be opened. When the control lever 1 is rotated counterclockwise to close it, the pawl claw 31 strongly hits the tooth surface 21 as it climbs over the peak of the tooth profile of the ratchet rack 2 and reaches the next valley (see Fig. 5). ), it had the disadvantage of producing a continuous metal impact sound.

In the present invention, the control lever 1 to which the wire 7 is connected as described above is connected to the ratchet rack 2, the pawl 3, and the cam 42.
In the automobile window opening/closing bundle device, which has a braking mechanism consisting of a bundle 4 having the following structure and a spring 5 that rotationally biases the pawl 3 and the cam 4, when the control lever 1 is stopped, the spring 5 biases the spring 5 to rotate. By holding the pawl 3 around its support shaft 32 and bringing the left side opposite to the claw portion 31 into abutment engagement with the cam 42 surface of the bundle 4 in the restrained state, the pawl 3 is completely moved by the action of the spring 5 and the cam 42. Focusing on the fact that it can be stopped, control lever 1
When the pawl claw part 31 is stopped, the pawl claw part 31 is lifted from the tooth surface 21 of the ratchet rack 2, and a mechanism has been devised to hold it in a state where it does not abut and engage with the pawl claw part 31, thereby completing a device that eliminates the above-mentioned drawbacks. The present invention will be explained according to an embodiment shown in the drawings.

That is, the present invention has a base mounted near the driver's seat in the passenger compartment and a base mounted on the base vertical wall 6 so as to be rotatable at one end so as to be able to remotely open and close the window glass which is hinged on one side. A control lever 1, a ratchet rack 2 formed on the vertical wall 6 in an arc shape centered on the support shaft 13 of the control lever 1, and a ratchet rack 2 rotatably attached to the free end side of the control lever and engaged with each other. An automobile window opening/closing bundle device is composed of a pole 3 and a bundle 4 that fit together, and a spring 5 that biases the pole 3 and bundle 4 to rotate. A claw portion 31 that engages with the rack 2 is formed at one end, and a mounting portion 33 for the spring 5 is formed at the other end.The bundle 4 also has a cam 42, a bundle lever 43, and a spring 5.
An arm 44 to which the bundle 4 is attached and a protrusion 45 that engages with the stopper 12 provided on the control lever 1 are respectively formed to position the bundle 4 above the pole 3, and a spring 5 is attached between the pole 3 and the bundle 4. The pawl 3 is suspended between the rack 2 and the rack 2, and the bundle 4 is rotated in a direction in which it does not act on the pawl 3. Thus, the window glass and the control lever 1 are In the automobile window opening/closing bundle, the pawl 3 is rotatably biased in the direction of meshing with the rack 2 by the action of the spring 5 when the control lever 1 is stopped. In order to stop this before the claw portion 31 side comes into contact with the toothed surface 21 of the rack 2, the portion of the pole 3 on the left side of the shaft support 32 is brought into abutting engagement with the cam 42 surface of the bundle 4, as shown in FIG. The pole claw portion 31 side is held in a state 9 in which it is lifted from the rack tooth profile surface 21.

In this case, the raised height is preferably about 1/2 to 2/3 of the tooth pattern, and as shown in Fig.
It is preferable to attach a low friction material 10, such as nylon, which has a property of mitigating the occurrence of impact noise, to one or both of the abutting and engaging parts of the parts 2.

In the present invention, the bundle 4 has a cam surface 42 consisting of a straight section long enough to stably hold the pawl 3 in a restrained state and an arcuate curved section connected to the straight section at one end, and the control lever During braking in step 1, the straight part of the cam surface 42 contacts the pawl 3 and holds it in mesh with the ratchet rack 2. Therefore, preferably, the straight part of the cam surface 42 stably holds the pawl 3 between the cam surface 42 and the pawl 3. It is preferable that the structure is formed so as to obtain a sufficiently large retention area.

In the present invention, as described above, the pawl portion 31 of the pawl 3 is lifted from the tooth-shaped surface 21 of the ratchet rack 2, so that when the pawl pawl portion 31 climbs over the tooth peak and reaches the next valley, the pawl pawl portion 31 , the control lever 1 can be rotated counterclockwise without colliding with the tooth surface 21 of the valley, and because a cushioning material is provided on both or either of the pawl 3 and the cam 42 to reduce the impact between them. Then, when the pawl 3 climbs over the tooth crest of the ratchet rack 2, a part of the pawl 3 separates from the cam surface 42 (see the imaginary diagram in FIG. 1), and after passing over the tooth ridge, collides with the cam 4 again. , at this time the cam surface 42
However, since the impact noise during this time is prevented by the cushioning material, no metallic sound is generated between the pawl 3 and the ratchet rack 2 when the control lever 1 is rotated to close the window.

Therefore, the present invention has the advantage of being able to solve the troublesome problem of preventing the generation of unpleasant noises with an extremely simple configuration.
