Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding roof device for opening and closing an opening in an automobile roof.

Sliding roof devices that move the entire sliding roof uniformly up and down, fitting it into an opening in the roof to close or open the opening, do not damage the rubber seal attached to the entire periphery of the sliding roof. However, when using a link mechanism as a mechanism to move the link up and down, it is necessary to raise the link at a slight angle from the dead center position to smoothly start the link operation. It takes.

Of course, it is also conceivable for the mechanism to set the link mechanism so that the link is out of the dead center state when it is in the non-operating state, but in that case, when transmitting horizontal motion to the sliding roof, It is necessary to provide a separate means to prevent the links from standing up any further to prevent the link from operating unnecessarily during horizontal movement and causing the sliding roof to rise, and the drawback is that the entire sliding roof becomes thicker. There is.

The present invention is to transmit horizontal movement to the sliding roof through the link mechanism while it is held at the dead center state, and to escape from the dead center state and cause the link to operate (thereby causing the sliding roof to rise In a sliding roof device configured to move, the sliding roof is pulled out horizontally from a door pocket, and then raised and fitted into a roof opening to close the closing stroke on the sliding path of the sliding roof. A second cam mechanism is interposed between the sliding roof and the fixed part of the attic, and the timing of engagement of the cam or cam follower is interposed between the sliding roof and the fixed part of the attic. It is equipped with adjustment means.

As a result, during the horizontal transition, the transmission of horizontal motion to the sliding roof is ensured via the link mechanism in the dead center state, and at the end of the horizontal transition, the link operation is reliably activated to move the sliding roof. In addition to the advantage that the roof opening can be reliably closed by raising the roof opening, and the thickness of the sliding roof can be reduced accordingly, the assembly can sometimes be performed by adjusting the engagement timing of the aforementioned cam and cam follower. It also has the advantage of being able to

In the embodiment described below, the cam and cam follower of the second cam mechanism are fastened to an inclined plate having a cam slope mounted on a guide rail, and to a sliding attic surface, respectively.
Although the present invention has been described as consisting of an adjustment plate that is pivotally connected to the sliding roof, the present invention is not limited to this. This goal can be achieved by intervening.

Assume that the left side of FIG. 1 is the forward direction of the automobile, and the right side is the rear direction.

A rectangular opening 1a is provided in the roof 1, and a sliding roof 2 is fitted into this as shown in the figure to close this 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 rainwater from entering when the roof is closed.

As shown in Figures 4 and 5, there is a reinforcing plate 1 on the back side of the roof 1.
4, and a frame 7 is fixed to the back side of this reinforcing plate 14.

As shown by the dotted line in FIG. 1, the frame 7 has an opening lower a which is slightly smaller than the opening 1a. As can be seen from FIG. 1, the position of the opening lower a is slightly shifted to the rear of the opening 1a.

A space is created between the opening lower door a and the roof 1 to form a door pocket 7c, and the sliding roof 2 is housed in the opening 1.
As shown in FIGS. 4 and 5, the frame 7 that opens a provides a rain gutter 7b on both sides of the opening in the attic.

Guide rails 18 (FIGS. 4 and 5) are provided on the inside of both rain gutters.

The guide rail 18 has a front shoe 3 as shown in FIG.
0 is slidably fitted.

The shoe 30 is located at No. 9 when viewed in the direction of arrow A' in FIG.
As shown in the lower part of the figure, a diagonal cam groove or elongated hole 30
It has two walls 30c with a wall 30c, into which a pin 31 can be slid (inserted).

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

A trochanter 33 is rotatably fitted into the pin 31 between the walls 30c, and the trochanter 33 rolls on the slope 30b (FIG. 8).

The slope angle of the slope 30b is equal to the angle of the long hole 30a, which is 0''.
0 As shown in the upper part of FIG. 9, a rear shoe 40 is further fitted into the guide rail 18 and slides thereon.

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

Both shoes 30 and 40 are connected by a link 42, and the shoes 30 and 40 are integrally moved on the guide rail 18 at a constant interval.
It slides in the left and right directions in the figure.

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.

Although the state in which the arm 43 is fixed to the reinforcing plate is not shown, it is the same as the method for fixing the arm 32 in FIG. 8.

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

The front shoe 30 in the lower part 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 device 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 protrusion 30d of the shoe 30 is fixed to the cable 46 as shown.

Although the cable is flexible, it fits completely inside the guide groove 18a and does not bend, so it can apply force to the shoe 30 in the right direction in FIG. 9.
1 is a drive gear, and 048 (FIG. 1), which meshes with the teeth of the toothed cable 46, is a drive shaft 1 that supports and rotates the gear 47.

1 drive shaft 48 is driven by a drive device 49 (FIG. 1) via a bevel gear mechanism 50.

With the structure explained above, the sliding roof 2 slides on the guide rail 18 in the left-right direction in FIG. If it is not raised, it will not fit properly into the opening 1a.

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

As shown by reference numeral 4 in FIG. 1, stop adjustment plates 4 for adjusting the stop position are installed on both sides of the back surface of the sliding roof 2, and the sliding roof 2 is stopped from moving laterally to the left by colliding with this plate. Stopper 8
is fixed to frame 7.

This structure is best illustrated in cross section in FIGS. 2 and 3.

The stop adjustment plate 4 is swingably attached to the reinforcing plate 13 with a pin 12 through a long hole 4a at one end, a bolt 10, and a nut 11.
It is tightened to the reinforcing plate 13 so that it can be loosened.

It swings around the pin 12 as shown by the chain line in Figure 3,
Adjust and tighten the stopper 8.

The outer surface of the stopper 8 is covered with a cushioning elastic material.

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

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 guide it to rain gutters 7 on both sides of the roof by utilizing its arcuate curvature.

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

The mounting position is shown by dotted lines in Figure 1. The rain catch of the adjusting plate 5 is pivotally connected to the plate 6 by a pin 17 (FIGS. 4 to 6), and the rain catch is relatably tightened to the plate 6 by a long hole 5a at one end, a bolt 15, and a nut 16.

The adjustment plate 5 is swung as shown by the two-dot chain line in FIG. 6 to tighten the nut 16 and 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, and as shown in FIGS.
As shown in the figure, it has a cam surface, which engages with the contact end 5b of the adjustment plate 5 moving in the direction of arrow A, and by 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 beginning, and both shoes were now 30.40.
As a result, the sliding roof 2 is raised in the direction of the arrow B, and is fitted into the edge of the upper opening 1a and closed.

In order to raise the sliding roof 2 in the direction of arrow B and close the opening, the sliding roof 2 must be correctly positioned directly below the opening 1a.

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

The sliding roof 2 that was housed in the right door pocket 7c in Fig.
When the adjusting plate 4 hits the stopper 8 and stops when it is pulled out to the left to close the opening 1a, the contact end 5b of the other adjusting plate 5 is discarded as shown in FIG. niP
Immediately after reaching the OQ position, which must be reached after passing through the OQ position, the contact end 5b is slightly raised to the H position by the cam action of the inclined plate 9.

Due to this rise, the pins 60 and 61 of the link 41, which had been in a dead center relationship as shown in the upper part of FIG. 10, change their dead center relationship and can now perform a link action.

In short, the stop adjustment plate 4 correctly stops the sliding roof immediately below the opening 1a, and at the same time, the other adjustment plate 5 creates a starting point for the sliding roof to rise.

To summarize the operation of the sliding roof device of the present invention as described above, the sliding roof 2 moves horizontally from the open position to the closed position, and then maintains its horizontal state.
The sliding roof 2 moves vertically upward and fits into the opening 1a of the roof to close the opening 1a, and moves in the opposite direction to the sliding roof 2.
open.

A sliding roof 2 is bowed to the left from the door pocket 7c (Fig. 1),
The state shown in FIG. 10 is when the robot is stopped directly below the opening 1a.

Until reaching this S, the cable 4 is connected to the drive device 49.
The indexing force transmitted to shoe 30 via link 42 is also transmitted to the other shoe 40 via link 42, and both shoes move in the direction of arrow A in FIG. 10 as a unit.

This indexing force causes the link 41 of the shoe 40 to move to the dead center position (
10: and the side thrust of the cam slope 30b (FIG. 8) of the other shoe 30 against the cam follower, the transmission is reliably transmitted to the sliding roof 2. The sliding roof 2 does not rise unnecessarily until it reaches the position.

A spring 44 (Fig. 9) performs an auxiliary action to maintain this dead center state.

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

At this stop position, the rear adjustment plate 5 assumes the Q position shown in FIG. 7, and is actuated by the inclined plate 9 to rise slightly, releasing the dead center position of the link 41 as shown in FIG. 10.

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.

Due to this rising and the cam action of the shoe 30, the sliding roof 2 is finally closed to the state shown in FIG. 9.

Next, when opening the sliding roof 2, the movement of the cable 46 immediately after starting is such that the link 41, which is standing up as shown in FIG. 9, is tilted to the left as shown in FIG. 30 pins 31 are first spent lowering from the state of FIG. 9 to the state of FIG. 10.

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

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

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

Although not shown, since 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, the vertical distance between them is as shown in FIGS. 4 and 5. It can change to

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

Therefore, when assembling, all the bolts are loosened, and the sliding roof 2 is placed in the correct position directly below the opening 1a. In this state, the adjustment plate 4 is brought into contact with the stopper 8, and is brought into contact with the inclined plate 9. By placing the portion 5b in the Q position and tightening each bolt, correct operating conditions can be set.
