Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a sliding member in which a guide rail is fitted to one of a vehicle body and a slide door, and the other is slidably fitted to the guide rail. And a sliding member sliding along a guide rail so that the sliding door opens and closes with respect to the vehicle body.

[Conventional technology]

An example of such a guide device for a slide door is disclosed in Japanese Utility Model Laid-Open No. 57-45424.

In this conventional device, in order to make the sliding member slide smoothly with respect to the guide rail, an upper piece provided with V-shaped grooves facing each other at the upper and lower edges of the base piece that faces the guide rail in the vertical direction. Also, the lower piece is connected in series, and the sliding member is provided with a guide roller adapted to roll in each V-shaped groove of the guide rail.

[Problems to be solved by the invention]

In the conventional device as described above, in order to allow each guide roller to smoothly roll in the V-shaped groove, in order to smoothly roll each guide roller, a slight dimensional error of the guide rail, the guide roller, or the like and an influence of thermal expansion are caused. In consideration of the above, the dimension between the upper and lower guide rollers on the sliding member side should be made slightly smaller than the dimension between the upper and lower V-shaped grooves in the guide rail to allow a certain amount of allowance for their engagement. I have to keep it.

However, if there is such an allowance for the engagement between the guide rail and the guide roller, the sliding member rattles in the guide rail when the sliding door is opened and closed, and abnormal noise is generated, or the sliding member guides. There is a problem that the slide door is slightly tilted laterally with respect to the vehicle body by tilting laterally in the rail.

In addition, the margin allowance on the engagement between the guide rail and the guide roller is not always constant because it varies due to dimensional error, outside temperature, etc., and once manufactured, the margin allowance cannot be adjusted. There is a problem.

An object of the present invention is to provide a vehicle slide door guide device that solves such problems.

[Means for solving problems]

In the guide device for a sliding door for a vehicle according to the present invention, a guide rail is provided with an upper piece and a lower piece having V-shaped grooves on the surfaces facing each other, which are connected to upper and lower edges of a base piece which faces the vertical direction. And a guide roller adapted to roll along each surface of each V-shaped groove in the guide rail, the base member being oriented in the vertical direction on the guide rail. It is characterized in that a sub roller adapted to roll along is provided so that the mounting position can be adjusted in a direction orthogonal to the surface of the base piece.

[Action]

According to the vehicle slide door guide device of the present invention, by adjusting the mounting position of the sub-roller, it is possible to adjust the allowance of the engagement of the guide roller with the guide rail even after manufacturing.

Secured with bolts (30).

On the inner surface of the base piece (22c) at the rear end of the guide rail (22), when the sliding door (3) reaches the front end position with respect to the sliding member (11), the sliding member (11) A stopper (31), which comes into contact with the rear end and prevents the sliding door (3) from moving further forward with respect to the sliding member (11), is fixed with a bolt (32).

The base piece (22
A pin-shaped striker (33) is fixed to the inner surface of c) so as to project inward.

A notch (34) is formed in an intermediate portion of the sliding member (11) so that the striker (33) can enter when the sliding door (3) advances to the above-mentioned front end position.

(35) is a switching lever pivotally mounted in the sliding member (11) with a shaft (36) directed in the up-down direction, and through the notch (34),
First arm part (35a) plunging into the movement path of the striker (33)
And the second arm portion (35b) that projects rearward at an included angle of approximately 90 ° with the first arm portion (35a) and the first arm portion (35a) has a relationship of approximately 180 °. Third arm that protrudes inward
(35c) and the second arm (35b) above the second arm (35b)
And a fourth arm portion (35d) having the same shape and pointing in the same direction.

Each end of the tension spring (38) is locked to the third arm (35c) and the pin (37) protruding from the inner surface of the sliding member (11) in front of the third arm (35c). Switch lever by (38)
(35) is always urged counterclockwise in FIG.

A fan-shaped cam portion (39) having an opening angle of approximately 90 ° is continuously provided on the peripheral edge around the shaft (13) at the tip of the rear rotating arm (8). On the outer periphery of the switch lever (3
The fourth arm portion (35d) of 5) slides or the tip of the fourth arm portion (35d) engages with the engaging portion (40) formed by the front edge of the cam portion (39). I'm supposed to get it.

As shown by the phantom line in FIG. 3, the switching lever (35) has both pivot arms (7) and (8) facing the front of the vehicle body (1), and the slide door (3) in the fully closed position. Both rotating arms from the position
(7) (8) pivots outwards and rear pivot arm (8)
However, until the state immediately before contacting the stopper (41) provided on the base member (6), the tip end of the fourth arm portion (35d) remains at the cam portion (3
9) is in contact with the outer periphery of the first arm portion (35a) and the second arm portion (35b)
By pushing the striker (33) from the front and back, the striker (33) and the slide door (3) integrally formed with the striker (33) are located at the slide prevention position that prevents the slide door (3) from sliding in the front-rear direction, and the rearward rotation is prevented. When the arm (8) reaches the position immediately before contacting the stopper (41), as shown by the solid line in FIG. 3, the fourth arm portion (35d)
Is engaged with the engaging portion (40) to rotate the arm relative to the sliding member (11).
The clockwise rotation of (8) is blocked, and the second arm portion (35b) deviates inward from the movement track of the striker (33), and the striker
(33) and the slide door (3) are located at a rotation-preventing position that allows sliding of the entire slide door (3) to the rear.

Next, the operation of this embodiment will be described.

As shown by the phantom line in FIG. 3, when the slide door (3) is in the fully closed position, both pivot arms (7) (8) face forward and the switching lever (35) slides. Located at the motion blocking position, the striker (33) is connected to the first arm (35a) of the switching lever (35) and the second arm (35a).
It is pinched and constrained by the arm (35b),
The sliding door (3) is locked with respect to the sliding member (11).

From this state, when the door lock (not shown) is released and the slide door (3) is opened, both rotating arms (7) and (8) move counterclockwise in FIG. 3 with respect to the vehicle body (1). Rotate toward.

At this time, since the switching lever (35) is maintained at the sliding prevention position, the sliding door (3) does not slide in the front-rear direction with respect to the sliding member (11).

When both rotating arms (7) and (8) rotate to a direction substantially orthogonal to the side surface of the vehicle body (1), the cam portion (39) causes the switching lever (35).
It comes off from the tip of the 4th arm part (35d), and the switching lever (35)
Is rotated to the rotation blocking position by the urging force of the tension spring (38).

Then, the tip end of the fourth arm portion (35d) of the switching lever (35) engages with the engaging portion (40) to prevent the turning arm (8) from returning clockwise in FIG. And the second arm (35
b) deviates from the trajectory of the striker (33), and the striker (3
Sliding of 3) and the sliding door (3) to the rear is allowed.

Immediately after the switching lever (35) is switched to the rotation blocking position side, the rotation arm (8) contacts the stopper (41), and the third arm
Further rotation in the counterclockwise direction in the figure is prevented, so that both rotation arms (7), (8) and the sliding member (11) are completely restrained at the position shown by the solid line in FIG. It

From this state, push the slide door (3) backward and the guide rollers (14) (15) and the sub roller (20) will move to the guide rail (2
By rolling relatively along the inner surface of (2), the guide rail (22) and the slide door (3) move backward relative to the sliding member (11) in parallel with the side surface of the vehicle body (1). It can be moved smoothly toward.

Immediately before the rotation arm (8) contacts the stopper (41), the switching lever (35) is switched to the rotation blocking position side and the striker (33) is released from the restraint.
Due to its inertia, (3) smoothly shifts from the outward swinging movement of the vehicle body (1) to the backward linear movement.

When the sliding door (3) reaches the end position, the stopper (27)
Comes into contact with the front end of the sliding member (11), and the chevron bend (29a) of the leaf spring (29) engages with the recess (28), and the slide door (3) stops at the fully open position, and It is held by a moderate elastic restraint force.

To close the sliding door (3) from the fully open position to the fully closed position, pull the sliding door (3) forward with a strong force due to the restraining force of the leaf spring (29).

Then, the mountain-shaped bent portion (29a) of the leaf spring (29) comes out of the recess (28), the guide rail (22) is guided by the guide rollers (14) (15) and the sub-roller (20), and the sliding member ( Sliding forward against 11).

Immediately before the guide rail (22) reaches the limit position, the striker (33) contacts the first arm portion (35a) of the switching lever (35), and the switching lever (35) causes the tension spring (38) to move. The striker (33) is rotated against the biasing force of the
Is the first arm portion (35a) and the second arm portion (35b) of the switching lever (35).
Sandwiched between and.

Almost at the same time or immediately after that, when the stopper (31) contacts the rear end of the sliding member (11), the inertia force of the sliding door (3) pushes the sliding member (11) forward. As a result, both pivot arms (7) and (8) try to pivot clockwise in FIG.

At this time, the switching lever (35) has already been rotated to the sliding prevention position as described above, and the fourth arm portion (35
Since d) is disengaged from the engaging portion (40), the rotation of both rotating arms (7) and (8) at this time is allowed.

When the rotating arm (8) slightly rotates clockwise from the position shown by the solid line in FIG. 3, the fourth arm portion (35) of the switching lever (35) is moved.
The cam portion (39) enters between the tip of d) and the shaft (13), and thereafter, the tip of the fourth arm portion (35d) abuts on the outer circumference of the cam portion (39) to switch. The return rotation of the lever (35) to the rotation blocking position side is blocked, and the striker (33) moves to the first arm (3
The slide door (3) is restrained in a state of being sandwiched by the 5a) and the second arm portion (35b), and the relative movement of the slide door (3) with respect to the sliding member (11) is prevented.

In this way, the sliding door (3) smoothly shifts from the forward linear motion to the sliding motion toward the side surface of the vehicle body (1), and when the fully closed position is reached, the door lock is engaged, Held in that position.

At this time, both the rotating arms (7) and (8), the switching lever (35) and the like are maintained in the original state.

When the sliding member (11) rattles in the guide rail (22), loosen the bolt (19) and move the sub roller (20) to the base piece (22).
Push the support plate (17) outward until it is in close contact with (c), and then tighten the bolt (19) again in this state to allow for the allowance for the engagement between the guide rail (22) and the guide rollers (14) (15). Can be made small to eliminate rattling of the sliding member (11).

Also, while opening and closing the slide door (3), the guide roller (14)
(15) causes so-called biting on the guide rail (22),
If the sliding member (11) causes sliding failure, bolts
It suffices to loosen (19), slightly move the support plate (17) in the opposite direction to the above case, and retighten the bolt (19) again.

[Modification]

In the above embodiment, the sub roller (20) is a sliding member.
The (11) is provided with its position adjustable through the long hole (18), but the sub roller (20) is provided on the sliding member (11) so as to be movable in the vehicle width direction, and an elastic body is used. Always urged to the outside of the car,
The tip may be pressed against the base piece (22c) of the guide rail (22).

In this case, rattling between the sub roller (20) and the guide rail (22) can be automatically absorbed.

Further, in the above-mentioned embodiment, the sliding member is provided on the vehicle body (1) side.
(11) and guide rails (2
Although 2) is provided, conversely, the present invention can be implemented by providing a guide rail on the vehicle body side and a sliding member on the slide door (3) side.

[Effect of device]

As is apparent from the above, in the present invention, in addition to the guide rollers that roll in the V-shaped grooves formed on the upper piece and the lower piece of the guide rail, the guide roller is oriented in the vertical direction. The sub-roller, which is adapted to roll along the base piece, is provided on the sliding member so that the mounting position can be adjusted in the direction orthogonal to the surface of the base piece. The allowance of the engagement of each guide roller with the rail can be adjusted individually even after manufacturing. The allowance is always kept at the optimum value and the sliding member always slides smoothly along the guide rail. There is an advantage that can be done.

In addition, since the sub-roller is disposed in the guide rail in a well-balanced manner together with the guide roller, the sub-roller is efficiently absorbed, and the guide rail is not increased in size, which is very practical.
