Description

DETAILED DESCRIPTION OF THE PRESENT EMBODIMENT The present invention relates to a sliding roof device for opening and closing a skylight-like opening in a roof of an automobile.

A sliding roof device in which the entire sliding roof moves up and down uniformly to fit into or out of a roof opening is advantageous because it can obtain a strong seal without damaging the seal attached to the periphery of the sliding roof. However, in order to achieve this, when closing the roof opening, the sliding roof must first be positioned correctly directly below the opening, and then it must perform an upward movement to fit into the opening.

Therefore, a stopper mechanism that accurately stops the lateral movement of the sliding roof at a predetermined position when the sliding roof moves laterally for closing is of primary importance.

In the present invention, a stopper means is provided between the sliding roof and the attic fixing point so that the engagement timing can be adjusted by swinging in the longitudinal direction of the automobile.

This allows the sliding roof to be positioned correctly directly below the roof opening at the end of its horizontal stroke, and then to rise and fit into the roof opening to reliably close it.It also has the advantage that the retention timing of the stopper means can be adjusted while it is in the assembled state during assembly.

In the embodiment described below, the stopper means is composed of an adjustment plate pivotally attached to the underside of the sliding roof so that it can be tightened and loosened, and a stopper attached to the attic fixing point, but the present invention is not limited to this, and the same purpose can be achieved even if only the stopper is attached so that its position can be adjusted.

The left side of FIG. 1 is the forward direction of the car, and the right side is the rear.

A rectangular opening 1a is provided in the roof 1, and a sliding roof 2 fits into this opening as shown in the figure to close the opening.

The seal 3 (FIGS. 8 and 1) is attached around the periphery of the sliding roof 2, filling the gap with the opening 1a and preventing the intrusion of rainwater etc. when the roof is closed.

As shown in Figs. 4 and 5, the underside of the roof 1 is provided with a reinforcing plate 1.
4, and the frame 1 is fixed to the rear side of the reinforcing plate 14.

As shown by the dotted line in FIG. 1, the frame 7 has an opening 1a that is slightly smaller than the opening 1a.

As can be seen from FIG. 1, the position of the opening lower portion a is shifted slightly rearward from the opening 1a.

The right part of the opening floor a is spaced from the roof 1 to form a door pocket IC, in which the sliding roof 2 is housed to accommodate the opening 1.
Open a.

As shown in Figs. 4 and 5, the frame 7 provides gutters 1b on both sides of the opening in the attic.

On the inside of both gutters, there are guide rails 18 (Figs. 4 and 5).
This is the setup.

As shown in FIG. 8, the guide rail 18 is fitted with a front shoe 3.
0 fits slidably.

The shoe 30 is the ninth one when viewed in the direction of the arrows A' and J in FIG.
As shown in the lower part of the figure, a diagonal cam groove, i.e., a long hole 30
a, into which a pin 31 is slidably fitted.

Both ends of the pin 31 are supported by a forked arm 32 (FIG. 8), and the arm 32 is fixed to the back side of the sliding roof 2 via a reinforcing plate 13.

A roller 33 is rotatably fitted on the pin 31 between the two walls 30c, and the roller 33 rolls on the inclined surface 30b (FIG. 8).

The inclination angle of the inclined surface 30b is equal to the angle of the slot 30a.

As shown in the upper part of FIG. 9, a rear shoe 40 is further fitted on the guide rail 18 and slides thereon.

The fitting method is exactly the same as that of the front shoe 30 shown in the lower part of the figure.

The two shoes 30 and 40 are connected by a link 42 and slide integrally on the guy and trail 18 at a fixed interval in the left-right direction in FIG.

The shoe 40 is rotatably connected to an arm 43 via a small link 41 , and the arm 43 is fixed to the reinforcing plate 13 .

The manner in which the arm 43 is fixed to the reinforcing plate is not shown, but is similar to the method of fixing the arm 32 in FIG.

Reference numeral 44 shown in the upper part of FIG. 9 denotes an auxiliary spring, the right end of which is fixed to the shoe 40 and the other end of which is hooked on a lug 45 of the reinforcing plate 13, and which constantly urges the sliding roof 2 downward.

The front shoe 30 at the bottom of FIG. 9 is connected to a cable 46 and is slid along the guide rail 18 in the left-right direction in the figure by a separately provided drive unit 49 (FIG. 1).

As shown in FIG. 8, the guide rail 18 has a guide groove 18a into which the cable 46 is slidably inserted.

The protruding portion 30d of the shoe 30 is fixed to a cable 46 as shown in the figure.

Although the cable is flexible, it fits snugly within the guide groove 18a and is not curved, so that a force can be applied to the shoe 30 in the right direction in FIG.

A ninth driving gear 41 shown below is engaged with the teeth of the toothed cable 46.

48 (FIG. 1) is a drive shaft which supports and rotates the gear 47.

The drive shaft 48 is driven by a drive unit 49 (FIG. 1) through a bevel gear mechanism 50 .

With the structure described above, the sliding roof 2 slides on the guide rails 18 in the left-right direction in Figure 1 to open and close the opening 1a, but when closing it, it will not fit properly into the opening 1a unless it is correctly positioned directly below the opening 1a and then raised vertically.

The structure described below is a stopper structure for correctly stopping the sliding roof 2 directly below the opening 1a.

As shown by the reference numeral 4 in FIG. 1, stop adjustment plates 4 for adjusting the stop position are attached to both sides of the back surface of the sliding roof 2, and a stopper 8 is provided to stop the lateral movement of the sliding roof 2 to the left by hitting the stop adjustment plates 4.
is fixed to the frame 7.

This structure is best illustrated in cross section in FIGS.

The stop adjustment plate 4 is pivotally attached to the reinforcing plate 13 by a pin 12 and is loosely fastened to the reinforcing plate 13 by a long hole 4a at one end, a bolt 10 and a nut 11.

As shown by the dashed lines in FIG. 3, it swings around the pin 12 to adjust and tighten the stopper 8.

The outer surface of the stopper 8 is covered with a shock-absorbing elastic material.

Returning to FIG. 1, a long and narrow rain receiving plate 6 is attached to a reinforcing plate 13 at the rear end of the back surface of the sliding roof 2 .

Both receiving plates 6 have a cross-sectional shape as shown in FIG. 9, and receive rainwater leaking or dripping from the seal 3, and utilize their arcuate curvature to guide it to the rain gutters 1 on both sides of the roof.

As shown in Figs. 4 to 6, 9 and 10, the raised position adjustment plate 5 is attached to both ends of the rain catch plate 6.

The mounting position is shown by the dotted line in Fig. 1. The rain catcher of the adjusting plate 5 is pivotally attached to the plate 6 by a pin 11 (Figs. 4 to 6), and the rain catcher is loosely fastened to the plate 6 by a long hole 5a at one end, a bolt 15, and a nut 16.

As shown by the two-dot chain line in FIG. 6, the adjustment plate 5 is swung and the nut 16 is tightened to adjust the contact position with respect to the inclined plate 9.

The inclined plate 9 is fixed to the rain gutter 7b of the frame 7.
As shown in the figure, the cam surface engages with the contact end 5b of the adjustment plate 5 moving in the direction of the arrow A, and the cam action
The contact end 5b is slightly raised from the state shown in FIG. 10 to the state shown in FIG.

This slight increase was the starting point, and both shoes were 30.40.
As a result, the sliding roof 2 is raised in the direction of arrow B and fitted onto the edge of the upper opening 1a, thereby closing it.

In order to raise the sliding roof 2 in the direction of arrow B to close the opening, it is necessary that the sliding roof 2 is correctly positioned directly below the opening 1a by that point.

The stop 8 cooperates with the stop adjustment plate 4 to determine this correct stop position.

The sliding roof 2 that was stored in the right door pocket 7c in FIG.
When the adjustment plate 4 is pulled out to the left to close the opening 1a, the adjustment plate 4 hits the stopper 8 and stops at that position. At that position, the contact end 5b of the other adjustment plate 5 is already in the P position as shown in FIG.
The position must have been passed and the Q position must have been reached.

Immediately after reaching position Q, the contact end 5b rises slightly to position R due to the cam action of the inclined plate 9.

This rise causes the pins 60, 61 of the link 41, which had been in a dead center relationship as shown in the upper part of FIG. 10, to change this dead center relationship and become able to perform a linking action.

In short, the stop adjusting plate 4 stops the sliding roof exactly below the opening 1a, and at the same time, the other adjusting plate 5 creates the starting point for the lifting of the sliding roof.

To summarize the operation of the sliding roof device of the present invention described above, the sliding roof 2 moves horizontally from the open position to the closed position, then moves vertically while maintaining the horizontal state to fit into the roof opening 1a, closing the opening 1a, and then moves in the exact opposite direction to close the sliding roof 2.
Open.

The sliding roof 2 is pulled to the left from the door pocket 7C (Fig. 1).
The state in which the nozzle stops exactly below the opening 1a is shown in FIG.

Until this point is reached, the cable 4 is driven by the drive unit 49.
The pulling force transmitted to the shoe 30 via the link 6 is also transmitted to the other shoe 40 via the link 42, and both shoes move integrally in the direction of the arrow A in FIG.

This pulling force occurs when the link 41 of the shoe 40 is in the dead center position (
10) and the side thrust of the cam inclined surface 30b (FIG. 8) of the other shoe 30 against the cam follower is reliably transmitted to the sliding roof 2, so that the sliding roof 2 does not rise uncontrollably until it reaches the position shown in FIG. 10.

A spring 44 (FIG. 9) acts to assist in maintaining this dead center condition.

The position of FIG. 10 is secured by the action of the stopper 8 and the adjustment plate 4.

At this stop position, the rear adjusting plate 5 takes the Q position in FIG. 7, and the inclined plate 9 is actuated to rise slightly, releasing the dead center position of the link 41 as shown in FIG.

The subsequent pulling force of the cable 46 is used to raise the link 41 as shown in FIG. 9 and to raise the pin 31 of the front shoe 30 by the cam action of the shoe.

By this raising and the cam action of the shoe 30, the sliding roof 2 is finally closed in the state shown in FIG.

Next, when the sliding roof 2 is opened, the movement of the cable 46 immediately after it is started is first used to tilt the link 41, which is standing as in Figure 9, to the left as shown in Figure 10, and at the same time to lower the pin 31 of the front shoe 30 from the state shown in Figure 9 (7) to the state shown in Figure 10.

As a result, the sliding roof 2 is lowered as shown in FIG. 10, and the subsequent rightward movement of both shoes 30, 40 causes the sliding roof 2 to be pushed into the door pocket 7c on the rear side of the roof 1.

When the sliding roof 2 moves vertically as described above, the interior plate 19 (
The vertical distance between the plate and the plate (Figures 4 and 5) increases or decreases.

This is because the interior plate 19 cannot move up and down as its side edges are guided by the guide rails 18 .

Although not shown, the sliding roof 2 and the interior panel 19 maintain an integral relationship only in the horizontal direction, and have a floating relationship in the vertical direction, so that the vertical distance between them can change as shown in Figs.

As explained above, the angles of the image adjustment plates 4 and 5 can be adjusted by loosening the bolts 10 and 15, respectively.

Therefore, when assembling, all bolts are loosened and the sliding roof 2 is correctly positioned directly below the opening 1a. In this state, the adjustment plate 4 is abutted against the stopper 8, and the contact part 5b with respect to the inclined plate 9 is placed in position Q, and then the bolts are tightened, thereby setting the correct operating conditions.
