Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a wire guiding device for guiding a wire for unlocking a locking device for locking an opening/closing body in a closed position at an operating position remote from the locking device.

Prior Art For example, an opening/closing body such as an automobile luggage door, an opening/closing lid for an engine room, an opening/closing lid for a fuel filler port, etc. is rotatably supported on a support such as a vehicle body.
It is well known in the art to lock the vehicle in the closed position by means of a locking device and to enable the locking device to be unlocked from an operating position remote from the locking device, for example from the driver's seat. In order to enable such remote control, the locking device and the operating side are connected by a wire, and the operating force applied on the operating side is transmitted to the locking device via the wire, but it is important to ensure that this force is transmitted reliably. The wire is guided by a wire guiding device as is done in the above. However, in the conventional wire guide device, the sliding resistance exerted on the wire is large, making it difficult to operate the wire smoothly. In addition, the opening/closing body operates in the vicinity of the wire transitioning from the support body side to the opening/closing body side, so when the opening/closing body opens, it receives excessive tensile force from this opening/closing body, which impedes smooth guidance of the wire. There was also the fear of being exposed.

Object The object of the invention is to provide a wire guiding device of the type mentioned at the outset, which eliminates the above-mentioned conventional drawbacks.

Configuration The present invention includes a first pulley rotatably supported on a support body that rotatably supports the opening/closing body, and a second pulley rotatably supported on the opening/closing body side.
A configuration is proposed in which a wire extending from the operating side to the locking device side is wound around the first and second pulleys in sequence.

Effect According to the above configuration, since the wire is guided by the pulley, the resistance force that the wire receives when operating the wire can be reduced, and the second pulley also moves against the support body during the opening/closing operation of the opening/closing body. Because it works,
No excessive external force is applied to the wire.

Embodiments Hereinafter, the present invention will be described in detail with reference to the drawings, with reference to the drawings, regarding an embodiment of the present invention configured as a guide device for a wire provided in a luggage door of an automobile.

In Figure 1, the rear of the car has its body 1.
A trunk room 2 is provided, the upper opening of which is opened and closed by a luggage door 3. This door 3 is rotatably supported by the vehicle body 1 via hinges 4, 4a in the directions of arrows A and B.

As clearly shown in FIGS. 2 to 4, the hinge 4 includes a fixed bracket 5 fixed to the vehicle body 1, a movable bracket 6 fixed to the door 3, and pins 7 and 8 attached to these brackets 5 and 6, respectively. The first pivot link 9 is pivotally connected to the pins 10 and 11.
A second rotation link 12 is pivotally connected to each bracket 6, 5 via a second rotation link 12, and the brackets 5, 6 and links 9, 12 constitute a four-bar rotation chain mechanism. The length of the second rotation link 12 is set shorter than the length of the first rotation link 9.

When door 3 is closed, bracket 5,
6 and links 9 and 12 are located as shown in FIGS. 3 and 4, respectively. When the door 3 is rotated in the direction of arrow A to open it, the first rotation link 9 and the second rotation link 12 are connected to the pins 8 and 11, respectively.
When the door 3 reaches the fully open position, these links 9 and 12 each rotate to the position shown in FIG. 2. When the door 3 is closed, the links 9, 12 are again rotated counterclockwise in FIG. 2 about the pins 8, 11, returning to the position shown in FIG. 3.

The other hinge 4a (FIG. 1) is constructed in exactly the same way as the hinge 4 shown in FIGS. 2 to 4,
There is no change in its operation, so a description of the hinge 4a will be omitted. In addition, door 3 and car body 1 have
As shown in FIG. 1, stay dampers 15, 15a having cylinders 13, 13a and rods 14, 14a fitted therein are connected, and when the door 3 is in the fully open position, these stay dampers 15, 15a are connected.
15a holds the door 3 in the fully open position.
The stay dampers 15, 15a are the same as those widely used in the back doors of van-type automobiles.

When the door 3 is closed, the door 3 is locked in the closed position by a locking device, and the locking device shown in FIG. It has an attached engagement member (not shown). The lock claw 16 is indicated by arrow C,
It can be slid in the D direction, and when the door 3 is closed, the lock pawl 16 engages with an engaging member on the vehicle body side to lock the door 3. By operating the lock pawl 16 in the direction of arrow D, the pawl 16 can be removed from the engagement member and the door can be unlocked.

Although the locking device described above can be unlocked by inserting a key into the keyhole of the door 3, the locking device is also configured to be able to perform this operation from the driver's seat side away from the locking device. That is, an operating member such as an operating knob provided on the driver's seat side is connected to the lock device via a wire, and when the operating member is operated, the operating force is transmitted to the lock device via the wire, and the lock pawl 16 is activated. The lock is unlocked by operating in the direction of arrow C.

The above-mentioned wire has one end connected to the operating member and extends inside the vehicle body 1, and then moves to the door 3 side and is connected to the lock claw 16 of the locking device. However, the wire that moves from the vehicle body side to the door side The section is guided by a wire guiding device 20 according to the invention.

As is clear from FIGS. 2 to 4, the guide device 20 shown as an example in the figure includes a first rotation link 9 rotatably supported by a pin 8 that pivotally supports the first rotation link 9 on the fixed bracket 5. a second pulley 22 rotatably supported by a pin 7 which also pivotally connects a first rotation link 9 to a movable bracket 6;
It has an arm 25 which carries a rotatable roller 23 at its tip and is rotatably supported by the fixed bracket 5 by a support pin 24. On the other hand, a wire 26 starting from the operating member on the operating side and extending inside the vehicle body 1 is connected to a grommet 27 fitted into a hole in the vehicle body 1.
The first pulley 21 and the roller 23 of the arm 25
and the second pulley 22, and then the door 3
It enters the space between the inner panel 3a and the outer panel 3b, and reaches the lock pawl 16 (FIG. 1).

With the door 3 closed and locked by the locking device as shown in FIGS. 3 and 4, when the operating member is operated on the driver's seat side and the wire 26 is pulled, the wire 26 is moved as shown in FIG. The wire 26 is pulled in the direction shown by the arrow E to activate the lock pawl 16 and release the locked state.
In the area where the wire 26 moves from the door 3 to the door 3, the wire 26 is guided while being changed in direction by the two rotatable pulleys 21 and 22, so the resistance acting on the wire 26 is extremely small and the wire 26 can be moved smoothly. can be activated.

When the door 3 is opened, the first rotating link 9 rotates as shown in FIG. 2, and at this time, the second pulley 22 also moves to the position shown in FIG. 2 with the link 9, with the wire 26 wound around it. Therefore, the distance along the wire 26 from the operating member to the lock pawl does not change significantly compared to when the door is closed, and no unreasonable tensile force is applied to the wire. Therefore, the wire can be reliably guided regardless of whether the door is opened or closed. If the second pulley is also provided on the vehicle body side, the above-mentioned distance will be larger when the door is opened than when it is closed, and there is a risk that an unreasonable tensile force will be applied to the wire.

However, the above-mentioned distance along the wire 26 is
It is slightly shorter when opened than when closed, and when door 3 is opened, wire 2
It is also conceivable that a slight slack may be formed in the wire 26 and the wire 26 may come off the pulleys 21 and 22.
To eliminate this fear, the arm 25 briefly shown above is used. That is, the roller 23 at the tip of the arm 25 engages with the wire portion between the first pulley 21 and the second pulley 22, and each end of the tension spring 28 is locked to the arm 25 and the fixed bracket 5.
This gives the arm 25 the clockwise rotational behavior in FIGS. 2 and 3. When the door 3 is closed, the arm 25 occupies the position shown in FIG.
It is lightly touching the part of the wire near the. At this time, it is preferable that the tension spring 28 exerts almost no tensile force on the arm 25. For this reason, the wire 26
is not significantly bent by the force exerted by the rollers 23. When the door 3 is opened, the first rotation link 9 and the second
As the pulley 22 rotates, both pulleys 21,
The wire portion between 22 also rotates clockwise, which biases roller 23 in a direction that causes arm 25 to rotate counterclockwise around its support pin 24, causing arm 25 and roller 23 to rotate clockwise. operates to the position shown in Figure 2. At this time, the tension spring 28 is stretched and its tensile action increases, and the roller 23 reaches the central region between the two pulleys 21 and 22 where the wire 26 tends to be bent.
6 as shown in FIG. 2 to prevent the wire 26 from becoming slack.

It goes without saying that the arm may be omitted if there is no particular problem even if the wire is slightly slack.

The case has been described above in which the opening/closing body is configured as a lug gauge door of an automobile, and the support body that rotatably supports the opening/closing body is configured as a vehicle body.
It is clear that the present invention can also be configured as a wire guide device provided in various opening/closing bodies.

In addition, in addition to the case where the transmission member connecting the operation side and the locking device side is entirely made of wire as described above, the part other than the part passing through the wire guide device is made of a material other than wire, such as a link. The present invention can be applied without any problem even when configured by

Effects According to the present invention, the wire can be operated smoothly and the operability of the wire can be improved. Further, when the opening/closing body is opened, the second pulley that guides the wire also operates, so that the wire can be guided without applying excessive external force to the wire.
In addition, since the wire is wrapped around the pulley, the tire does not sag significantly and has the secondary effect of improving its appearance.
