DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a remote device for a sliding door, and more particularly to a remote device for an inside door of a sliding door.

[0002]

2. Description of the Related Art FIG. 4 is a side view showing the engagement of a first lever A and a second lever B, and an operation explanatory diagram of the first lever A and the second lever B in a conventional remote control apparatus for a sliding door of an automobile. As shown in FIG. 5, the first lever A connected to the inside handle of the slide door is provided with an elongated engagement hole A1, and the second lever B connected to the slide door unlock link is provided with an engagement protrusion B1 for engagement. The hole A1 and the engagement protrusion B1 are engaged to transmit the rotation operation.

The shape of the engaging hole A1 of the conventional first lever A connected to the inside handle of the sliding door is a long and narrow hole having a constant width, and the width of the long hole is equal to that of the second lever B. The diameter of the engagement protrusion B1 is substantially the same as the diameter that can be engaged.

In a conventional sliding door, as shown in FIG. 5, an inside handle of the sliding door is pulled in a door unlocking direction OP, and a first lever A is rotated about a rotation center A0.
, The second lever B rotates in the F4 direction about the rotation center BO. At this time, the engagement projection B1 of the second lever B rotates while moving from the rotation locus about the rotation center BO to the end of the elongated engagement hole A1 of the first lever A.

The relationship between the operation load F3 of the first lever A due to the movement of the inside handle of the slide door and the operation load F4 of the second lever B for unlocking the door at the first lever A is as follows. It is as follows. F3
/ A = F4 / b (a is the distance from the rotation center A0 of the first lever to the engagement position AC at the start of the first lever operation, and b is the second
Distance from the lever rotation center B0 to the engagement position AC at which the second lever operation starts. )

Further, a state F3 'in which the inside handle of the sliding door is fully pulled in the door unlocking direction OP.
Since the engagement projection B1 of the second lever B is at the engagement position with respect to the tip of the engagement hole A1 of the first lever A, the relational expression is F3 '/ a' = F4 / b (a 'Is the distance from the rotation center A0 of the first lever A to the engagement position AD). F
4 / b is a constant output, so F3 ′ is a
Is a long extension of the distance of a ', a large lifting force is required. Therefore, the operation load becomes larger in the state F3 ′ in which the inside handle is pulled to the maximum in the door lock releasing direction OP than in the state in which the inside handle is started to be pulled.

[0007]

Therefore, the inside handle of the sliding door is moved in the door unlock direction OP more than when the inside handle is first pulled.
There is a problem that the operation load becomes larger and the operability and the operational sensation become worse in the state F3 'which is pulled to the maximum.

[0008]

[Means for solving the problem] To solve this problem,
A first lever connected to the inside handle of the slide door is provided with an engagement protrusion, and a second lever connected to the slide door lock release link is provided with an engagement hole having a curved edge,
The second lever is rotated by engaging the engagement protrusion of the first lever with the engagement hole of the second lever, and the engagement protrusion abuts along the curved edge of the engagement hole, thereby rotating the second lever. A remote device for a slide door, wherein a distance from a center of rotation to an engagement position between an engagement protrusion and an engagement hole is not changed by rotation of a first lever.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a partially enlarged front view of a remote device of an inside handle of a sliding door according to an embodiment of the present invention, FIG. 2 is also a partial side view, and operation of a first lever and a second lever. A description will be given based on FIG. 3 showing the principle.

Reference numeral 1 denotes a first lever, and 2 denotes a second lever.
The first lever 1 is connected to an inside handle of a slide door (not shown). The second lever 2 is connected to a slide door unlock link (not shown).

The first lever 1 rotates about a rotation center 10 and has an engagement projection 11 at the end of the lever. Engaging projection 1
Reference numeral 1 denotes a columnar projection formed of a pin and fixed to the rotating end of the lever.

The second lever 2 rotates about the center of rotation 20, and has an engagement hole 21 at the rotation end of the lever to engage with the engagement protrusion 11 of the first lever 1. The shape of the engagement hole 21 is
The inner edge of the hole is one curved edge 21a and two straight edges 21a.
b, 21c. The engagement hole 21 has a hole shape capable of engaging between an engagement position 31 corresponding to the maximum open position of the inside handle of the slide door and an engagement position 32 corresponding to the maximum close position of the inside handle of the slide door. is there. The engagement position 30 is an engagement position at the start of operation. The position of the engagement between the engagement protrusion 11 and the engagement hole 21 does not change with the rotation of the first lever 1 from the rotation center 10 of the first lever 1.

Next, the operation of the first lever 1 and the second lever 2 will be described. When the inside handle is pulled in the opening direction of the closed slide door, the first lever 1 rotates about the rotation center 10 in the direction of the arrow OP, and the engagement protrusion 11
Moves from the engagement position 30 at the start of the operation to the maximum open position 31. At this time, the engaging projection 11 rotates while rotating while moving along the curved edge 21a of the engaging hole 21, and stops between the curved edge 21a and the linear edge 21c. In this state, the second lever 2 operates the slide door lock release link in the lock release direction to release the lock of the slide door, and the slide door becomes openable.

When the inside handle is pulled in the closing direction to close the opened slide door, the first lever 1 rotates in the direction of arrow CR about the rotation center 10 and the engagement projection 11 is fully opened. Position 31 to maximum closed position 32
Go to At this time, the engagement protrusion 11 rotates while rotating while moving along the curved edge 21a of the engagement hole 21, and stops at the middle of the linear edge 21b. In this state, the second lever 2 operates the slide door lock release link in the locking direction to lock the slide door, and the slide door is closed.

Next, the operation principle of the first lever and the second lever will be described with reference to the operation principle diagram shown in FIG. When the inside handle of the sliding door is pulled in the door unlocking direction OP and the first lever 1 is rotated in the F1 direction about the rotation center 10, the second lever 2 rotates in the F2 direction about the rotation center 20. At this time, the engagement protrusions 11 of the first lever 1 move while abutting along the curved edge 21 a of the engagement hole 21, so that the engagement positions 30, 31, 32 for applying a rotational force to the engagement hole 21 are It does not deviate from the arc-shaped rotation locus of a circle centered on the rotation center 10. Therefore, the distance from the rotation center 10 of the first lever 1 to the engagement positions 30, 31, 32 between the engagement protrusions 11 and the engagement holes 21 does not change.

On the other hand, the engagement positions 30, 31, and 32 of the engagement holes 21 with the engagement protrusions 11 of the second lever 2 deviate from the rotation trajectory of the second lever 2, and the rotation center 2 of the second lever 2
The distance from 0 to the respective engagement positions 30, 31, 32 varies. That is, the distance b ′ from the rotation center 20 of the second lever 2 to the engagement position 31 corresponding to the maximum open position is longer than the distance b between the engagement positions 30 at the start of the operation of starting to pull the inside handle. Become.

Therefore, at the start of the operation of pulling the inside handle to open the closed slide door, the operation load F1 of the first lever 1 due to the movement of the inside handle and the second lever for releasing the door lock. The relational expression of the operation load F2 of No. 2 is as follows. F1 / a
= F2 / b (a is the distance from the rotation center 10 of the first lever 1 to the engagement positions 30, 31, 32, and b is the distance from the rotation center 20 of the second lever to the engagement position 30.)

Furthermore, a state F1 'in which the inside handle of the sliding door is pulled to the maximum in the door unlocking direction OP.
In this case, the distance b ′ from the rotation center 20 of the second lever 2 to the engagement position 31 in the engagement hole 21 of the second lever 2 is longer than the distance b from the engagement position 30 at the start of operation. The relational expression of the state F1 ′ in which the inside handle is fully pulled in the door unlocking direction OP is F1 ′ / a = F2 /
b ′ (b ′ is the distance from the rotation center 20 of the second lever 2 to the engagement position 31 corresponding to the maximum open position). Here, assuming that F2 / b 'is a constant output, F1' is smaller than F1 by b
The distance is longer than the distance of b '. Therefore, the operation load is gradually reduced in the state F1 ′ in which the inside handle is pulled to the maximum in the door unlocking direction OP from the operation start time F1 when the inside handle is started to be pulled, and the operation is possible even if the operation force is smaller. Therefore, operability is improved.

[0019]

The operation force at the end of operation of the inside handle of the sliding door is smaller than that at the start of operation, so that the operation feeling is improved and the operability is improved.

The operability can be improved without increasing the number of manufactured parts.
