You can Moreover, by selecting the engaging position of the protrusion and the groove, the distance between the operation knob and the operated body can be adjusted according to the distance between the support plate and the support member.

If the knob guide is attached to the support plate so as to prevent the operation knob from rotating after the protrusion and the groove are engaged, the engagement can be prevented from being disengaged.

(3) Embodiment Hereinafter, one embodiment of the present invention will be described with reference to the drawings. First, in FIG. 1 and FIG. 2, 1 is a sliding door of a wagon type automobile, and a large rectangular shape in the upper half part. Window 2
The window glass 3 for opening and closing the window 2 is driven up and down by the window regulator 4.

The door 1 is constructed by joining the peripheral edges of an outer plate 5 and an inner plate 6 to each other, and the window regulator 4 is housed in a vacant chamber 7 defined below the window 2 between the plates 5 and 6. The inner plate 6 corresponds to the support plate in the present invention.

The window regulator 4 includes a drive unit 9 mounted on the inner side surface of the inner plate 6 by disposing the regulator handle 8 outside the inner plate 6, that is, on the side of the vehicle compartment R, and the inner plate 6 also on one side of the drive unit 9. Guide rail 10 laid vertically on the inner surface of
And a wire 11 suspended between the guide rail 10 and the drive unit 9. At that time, the wire 11 is slidably supported by wire guides 12 and 13 attached to the upper and lower ends of the guide rail 10 so as to be along one side of the guide rail 10. As a result, the portion of the wire 11 along the guide rail 10 moves up and down.

As clearly shown in FIG. 7, a carrier plate 14 engaged with a guide rail 10 so as to be able to move up and down is connected to the wire 11 via a caulking member 15, and the carrier plate 14 is connected to the window glass 3 of the window glass 3. The lower end is fixed by a bolt 16.

Therefore, if the regulator handle 8 is rotated, the carrier plate is passed through the wire 11 depending on the rotation direction.
The window glass 3 can be moved up and down between the fully closed position and the fully open position by raising and lowering the window 14, and the window glass 3 is stored in the empty chamber 7 at the fully open position.

As shown in FIGS. 3 and 4, a lock housing 17 as a support member is provided at an intermediate portion in the vertical direction of the guide rail 10.
A holding plate 18 for holding is locked and a lock member 19 and a lock spring 20 as an operated body are housed in the lock housing 17.

The lock member 19 has a hook-shaped portion 19a bent upward at a tip end thereof, and a lock position L at which the hook-shaped portion 19a is projected into the ascending / descending path of the carrier plate 14 and the hook-shaped portion 19a are inside the lock housing 17. It can slide to and from the unlocked position U to be retracted, and the lock spring 20 constantly urges the lock member 19 toward the locked position L. The lock position L and the unlock position U of the lock member 19 are the protrusions provided on the side surface of the lock member 19.
21 is regulated by abutting on the end wall of the long hole 22 opening in the side wall of the lock housing 19.

The lower surface of the hook-shaped portion 19a of the lock member 19 is formed as a slope 23 that descends toward the root of the hook-shaped portion 19a.

On the other hand, the hook-shaped portion 19 is formed on the lower surface of the carrier plate 14.
A locking groove 24 that can be engaged with a is provided, and a slope 25 that can slidably contact the slope 23 is formed on the upper surface thereof.

An operating knob 26 arranged on the vehicle compartment R side of the door 1 is connected to the lock member 19 by the connecting structure of the present invention. That is, as shown in FIG. 5, the lock member 19 has a bottomed long hole 27.
On the other hand, the operation knob 26 is provided with a connector 28 having a flat, oval circular cross section, which is inserted through the inner plate 6 and the holding plate 18 of the door 1 and can be inserted into the elongated hole 27. A large number of recessed grooves 29 and protrusions 30 that can engage with each other are formed on the inner surface of the connector and the arc surface of the connector 28, respectively. When the connector 28 is inserted into the elongated hole 27, the operation knob 26 has a position between the attachment / detachment position in which the protrusion 30 and the concave groove 29 are in the non-engaged state and the use position in the engaged state. The connector 28 can rotate about 90 ° about its axis.

As shown in FIG. 6, the operation knob 26 has a rectangular cross section, and a synthetic resin knob guide 31 which is loosely fitted to the outer circumference of the operation knob 26 in a connected state with the lock member 19.
Is joined to the decorative plate 32 attached to the outer surface of the inner plate 6.
In this case, the knob guide 31 is joined to the decorative plate 32 by elastically engaging the pair of elastic claws 33 protruding from the back surface of the knob guide 31 with the locking holes 34 formed in the inner plate 6. .

Further, on the surface of the knob guide 31, a pair of projecting pieces 35 that are opposed to each other with the operation knob 26 sandwiched on the short side thereof are integrally formed, and these prevent malfunction of the operation knob 26 due to contact with another object. It has become.

Referring again to FIG. 2, the guide rail 10 is curved according to the curved shape outward of the door 1 and the window glass 3. Therefore, when the carrier plate 14 approaches the upper limit or the lower limit of the guide rail 10, Upper and lower wire guides 12, 13
The central portion of the wire 11 stretched between the two tends to move away from the guide rail 10 to the inner plate 6 side, but in order to prevent this,
When the central portion of the wire 11 is separated from the guide rail 10 by a certain distance toward the inner plate 6, a guide piece 36 (see FIGS. 4 and 7) that supports the wire 11 is formed integrally with the lock housing 17.

Next, the operation of this embodiment will be described.

When connecting the operation knob 26 to the lock member 19, first, the connector 28 is formed into a long hole until the operation knob 26 comes into contact with the outer surface of the inner plate 6.
When the operation knob 26 is inserted deeply into the lever 27, and then the operation knob 26 is rotated about 90 ° around the axis of the connector 28, the corresponding concave grooves 29 and the ridges 30 are engaged with each other, whereby the lock member 19 is operated by the operation knob 26.
Are connected. Therefore, even if there is some dimensional error in the distance between the inner plate 6 and the lock housing 17, the operation knob 26
Can be connected to the lock member 19 while maintaining proper relationship with the inner plate 6. In other words, the distance between the operation knob 26 and the lock member 19 can be freely adjusted by selecting the engaging position of the groove 29 and the protrusion 30.

After that, the knob guide 31 is fitted on the outer circumference of the operation knob 26, and the elasticity 33 of the knob guide 31 is elastically engaged with the locking hole 34 of the inner plate to join the knob guide 31 to the decorative plate 32. When the knob guide 31 is thus fixed, the rectangular operation knob 26 is prevented from rotating around the axis of the connector 28 by the knob guide 31, and the connected state with the lock member 19 is maintained.

Since the lock member 19 to which the operation knob 26 is connected is constantly urged toward the lock position L by the lock spring 20, normally the hook-shaped portion 19a is projected into the ascending / descending path of the carrier plate 14. There is. Therefore, when the window glass 3 is lowered from the fully closed position by rotating the regulator handle 8 as described above and the window 2 is opened to a predetermined intermediate opening degree, the locking groove 24 of the carrier plate 14 is locked by the locking member. 19
The lower part of the window glass 3 is stopped by engaging with the hook-shaped part 19a. Therefore, normally, the window glass 3 can be raised and lowered only within the range of the intermediate opening.

When the window glass 3 occupies the intermediate opening position, the engagement of the hook-shaped portion 19a and the locking groove 24 prevents the lock member 19 from moving to the unlock position L, so that the operation knob 26 The lock member 19 cannot be moved by pulling, which is effective in preventing mischief of the lock member 19.

Next, when it is necessary to further lower the window glass 3 at the intermediate opening position to open the window 2 greatly, the regulator handle 8 is operated to slightly raise the window glass 3 to temporarily engage the locking groove 24. Is separated from the hook-shaped portion 19a.

When the operation knob 26 is pulled toward the vehicle compartment R after this, the lock member 19 moves to the unlock position U against the force of the lock spring 20, and the hook-shaped portion 19a can be retracted into the lock housing 17. . When the regulator handle 8 is rotated in the descending direction of the window glass 3 while continuing to pull the operation knob 26, the carrier plate 14 passes immediately in front of the hook-shaped portion 19a without any interference with the lock member 19, and the window glass 3 can be lowered to its fully open position. Moreover, the operation knob 26 is similar to the regulator handle 8 in the door 1
Since it is arranged on the vehicle compartment R side, it is possible to easily release the opening regulation of the window glass 3 in the vehicle compartment R even while the vehicle is traveling.

When raising the window glass 3 in the fully open position, the operation knob 26
No pulling operation is required. This is because when the upper surface of the carrier plate 14 hits the lower surface of the hook-shaped portion 19a of the lock member 19 which occupies the lock position L as the window glass 3 rises, the slopes 23 and 25 of the lock members 19 come into sliding contact with each other and the carrier plate 14 is This is because the lock member 19 is retracted in the direction of the unlock position U against the force of the lock spring 20, and thus the carrier plate 14 and thus the window glass 3 are raised to the fully closed position without being interfered by the lock member 19. be able to.

C. Effect of the Invention According to the present invention as described above, a connector having a flattened circular cross section is continuously provided on the inner end of the operation knob, and a long hole into which the connector can be fitted is provided in the operated body. The outer peripheral surface of the connector and the inner surface of the elongated hole are engaged with each other at the operating position of the operating knob, and are disengaged at the attaching / detaching position where the operating knob is rotated about 90 ° around the axis of the connector from the operating position. A large number of ridges and recesses are formed respectively, and a knob guide for holding the operation knob in the use position is fixed to the support plate, so that a large number of ridges of the connector and a large number of grooves of the operated body are formed. By selecting the engagement position, the distance between the operation knob and the operated body can be adjusted according to the distance between the support plate and the support member, and both can be connected, and the knob guide is fixed to the support plate. By doing so, the connected state can be maintained. Moreover, the number of parts is small, the structure is extremely simple, and it can be provided at low cost.
