Description

[Detailed Description of the Invention] (Industrial Application Field) In the present invention, a hatch for opening and closing the roof opening of a vehicle is guided by a rail, and a sealing material that can come into contact with the inner edge of the hatch is attached to the roof opening. The present invention relates to a sliding roof hatch provided around the periphery of an opening.

(Prior Art) Conventionally, when trying to realize a sliding roof hatch, for example, a hatch for opening and closing the roof opening of a vehicle is guided by a rail, and a sealing material that can come into contact with the inner edge of the hatch is used. The hatch is provided around the periphery of the roof opening, and the hatch is guided by a rail approximately parallel to the roof in an approximately horizontal position between the fully closed position and the fully open position. It is conceivable that the entire inner edge of the sealing material is in contact with the sealing material.

However, in such a sliding roof hatch, if the inner edge of the hatch strongly contacts the sealing material in the fully closed position to ensure sufficient sealing performance of the hatch in the fully closed position, Since the hatch moves almost parallel to the roof while remaining in an almost horizontal position, the inside edge of the hatch always comes into strong contact with the sealing material during this movement, as in the case of the fully closed position. The dynamic resistance is large, making it difficult to open and close the hatch, and the sealing material is severely worn.
The durability of the sealing material deteriorates, and conversely, if the inside edge of the hatch is made to lightly touch the sealing material when the hatch is moved in order to improve the operability of opening and closing the hatch, the durability of the sealing material will deteriorate. Since the inner edge of the hatch only lightly contacts the sealing material in the closed position, there has been a problem in that it is not possible to secure a sufficient amount of sealing material for the hatch.

(Problems to be Solved by the Invention) The present invention was developed by focusing on the problems of the conventional technology. The purpose is to provide a sliding roof hatch with good operability.

(Means for solving the problem) The gist of the present invention to achieve this purpose is as follows:
In a sliding roof hatch in which the front and rear ends of the hatch for opening and closing the roof opening of the vehicle body are slidably guided on rails, the hatch is slidably opened and closed. A slide member guided by the rail is installed, the slide member has a triangular shape, one corner is pivotally connected to the slide member, and the above-mentioned slide member is attached to each corner of both ends of the side opposite to the one corner. A fitting portion is formed by pivotally mounting a roller that fits on the rail, and an end portion of the rail that the slide member reaches when the hatch is fully closed is expanded to form an escape portion in which the slide member can rotate. , an engaging portion is provided on one side of the sliding member near the roller that becomes the leading roller when the door is closed, and on the roof side;
An engaging pin is provided on the other side, and when the hatch is fully closed, the engaging portion and the engaging pin are fitted into the sliding member, and the sliding member rotates within the relief portion around the engaging pin to close the hatch. The sliding roof hatch is characterized in that the roof hatch is disposed close to a roof opening and in pressure contact with a sealing material.

(Function) In the sliding roof hatch, when the hatch is moved from the fully open position to the fully closed position in order to close the roof opening that is in the fully open state, the guided portion does not move until the hatch is close to the fully closed position. When the slide member is engaged and guided by the rail, thereby holding the slide member in the running position and lifting the front end of the hatch, and the engagement portion and the engagement pin engage with each other near the fully closed position. The sliding member rotates about the engagement pin from the running position to the low position, thereby pulling down the front end of the hatch until the inner edge of the hatch comes into pressure contact with the sealing material. It's summery.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

1 to 10 show an embodiment of the present invention.

As shown in FIGS. 1 and 2, a sliding roof hatch 2 is attached to a roof 10 of a vehicle 1 to open and close a roof opening 11 provided in the roof 10. As shown in FIGS.

This sliding roof hatch 2 includes a hatch 3 for opening and closing the roof opening 11, inner rails 4, 4 for guiding the hatch 3, and an outer rail 5 for guiding the hatch 3.
5 is provided.

Figures 2, 3 to 6, 9 and 10
As shown in the figure, a sealing material 13 that can come into contact with the inner edge 3a of the hatch 3 is provided around the peripheral edge 12a of the frame 12 that forms the roof opening 11.

As shown in FIGS. 2 to 7, each inner rail 4 extends along both inner side surfaces 12b of the fitting frame 1 and is fixed to the frame 12. As shown in FIGS.

As shown in FIGS. 1, 2, and 3, each outer rail 5 is parallel to each inner rail 4, is arranged rearwardly outward from each inner rail 4, and is fixed on the roof 10.

As shown in FIGS. 3 to 7, reinforcing plates 30 are fixed to both sides 3b of the front end of the hatch 3.
Each reinforcing plate 30 has a standing running posture (fourth
A slide member 6 is pivotally supported so as to be able to roll from a position shown in FIGS.

This slide member 6 is attached to the reinforcing plate 30 with bolts 3.
A triangular slide plate 60 pivoted by 1
As shown in FIG. 5, the guided portion 61 that engages and guides the inner rail 4 and holds the slide plate 60 in the running position until the fully closed position is reached, and the slide plate 6
Return spring 6 that biases 0 toward the running posture
It consists of 2.

As shown in FIGS. 3 to 6, this guided portion 61 includes a first roller 63 pivotally supported on one end of the bottom portion 60a of the slide plate 60, and a first roller 63 attached to the other end of the bottom portion 60a. It consists of two roller parts 64.

As shown in FIGS. 3 to 5 and 7, the second roller portion 64 includes a holder 65 that is fitted through the slide plate 60, and a holder 65 that is pivotally supported at one end of the holder 65. It consists of a second roller 66. At the other end of the holding body 65, a notch 65a is formed as an engaging portion that opens toward the front (leftward in FIGS. 3 to 5).

As shown in FIGS. 3, 4, and 7, the engagement pin 14, which engages with the notch 65a near the fully closed position and serves as the rotation center of the slide plate 60, is located at the bottom of the frame 12. Bracket 1 fixed to reinforcing member
It is protruding from 5.

As shown in Figures 3 to 5, the inner rail 4
, the first roller 63 and the second roller 6 of the guided portion 61 move from the fully open position to the vicinity of the fully closed position.
When the slide plate 60 rotates around the engagement pin 14 from a running position to a low position due to the engagement between the rail part 41 that guides the slider 6, the notch part 65a, and the engagement pin 14, the first roller 63 is interfered with. It is comprised of an escape part 42 that expands from the rail part 41 to prevent the rail part 41 from moving, and a stopper 43 that biases and holds the first roller 63 against the fully open side end 41a of the rail part 41 in the fully open position. As shown in FIG. 9, this stopper 43 includes a receiving portion 43a that receives the first roller 63 and absorbs the impact immediately before the fully open position, and a receiving portion 43a that absorbs the impact by receiving the first roller 63 at the fully open position, and a receiving portion 43a that supports the first roller 63 at the fully open position.
It is formed of an elastic member having a holding portion 43b that is biased and held.

As shown in FIGS. 1, 2, and 8, the roller 32 that is engaged and guided by the outer rail 5 is
It is pivotally supported by brackets 33 fixed to both rear ends 3c of the hatch 3.

1, 2, and 10, a striker S is provided at the center of the front end surface 12c of the frame 12.
A locking device R is attached to a mounting portion 34 formed inside the front end of the hatch 3, which engages the striker S in the fully closed position. An operating handle 35 for opening and closing the hatch 3 is pivotally supported at the bottom of the mounting portion 34 .
When grasping the operating handle 35 in the fully closed position and moving the hatch 3 to the fully open position, the operating handle 35
The operating handle 35 is connected to the locking device R via a connecting member 36 so that the locking device R is rotated from the solid line position to the chain line position in FIG. 10, and the locking device R and the striker S are disengaged.

In the sliding roof hatch 2 having the above configuration, when the hatch 3 is in the fully closed position as shown in FIG. 1, the sliding plate 60 resists the biasing force of the return spring 62 as shown in FIG. As a result, the front end 3d of the hatch 3 is lowered until the entire inner edge 3a of the hatch 3 comes into pressure contact with the sealing material 13, and as shown in FIG. By meshing R with the striker S, the hatch 3 is locked in the fully closed position.

When moving the hatch 3 from the fully closed position to the fully open position, grasp the operating handle 35 and move the hatch 3 toward the fully open position. First, the operating handle 35 moves from the solid line position to the chain line position in FIG. The locking device R and the striker S are disengaged from each other, and the hatch 3 is unlocked.

When the hatch 3 is unlocked, the slide plate 60 rotates about the engagement pin from the low position shown in FIG. 3 to the running position shown in FIG. The inner edge 3a separates from the sealing material 13.

When the operating handle 35 is grasped in this state (the state shown in FIG. 4) and the hatch 3 is moved to the fully open position, the first roller 63 of the slide member 6 begins to engage with the rail portion 41 of the inner rail 4. As shown in FIG. 5, the first roller 63 and the second roller 66 are engaged and guided by the rail portion 41, and the hatch 3 moves toward the fully open position (to the right in FIG. 5). At this time, the roller 32 is guided by the outer rail 5.

In this manner, when the hatch 3 moves toward the fully open position, the first roller 63 and the second roller 66 fit into the rail portion 41, and the slide plate 60 stands up stably so as not to fall. Since the hatch 3 is held in the running position, the front end 3d of the hatch 3 is lifted using the roller 32 as a fulcrum.
The inner edge 3a of the hatch 3 is separated from the sealing material 13.

When the hatch 3 moves to just before the fully open position, the first roller 63 moves to the receiving part 4 of the stopper 43.
3a, the first roller 63 hits the holding part 43 of the stopper 43 at the fully open position as shown in FIG.
b, it is biased and held in a position where it abuts against the fully open side end 41a. As a result, the hatch 3 is held in the fully open position shown in FIG. 2 by the stopper 43.

Conversely, in order to move the hatch 3 from the fully open position to the fully closed position, when the operating handle 35 is grasped and the hatch 3 is moved to the fully closed position, the first roller 63 comes off from the stopper 43 and the first roller 63 disengages from the stopper 43. The first roller 63 and the second roller 66 move leftward within the rail section 41 from the position shown in FIG.

When the hatch 3 reaches near the fully closed position, the first roller 63 and the second roller 66 move to the rail portion 4.
1, the notch 65a engages with the engagement pin 14, and the inertial force of the hatch 3 causes the slide plate 60 to rotate around the engagement pin 14 from the running position to the low position. This rotation causes the inner edge 3a of the hatch 3 to
The front end 3d of the hatch 3 is pushed down until it comes into pressure contact with the sealing material 13, the locking device R engages the striker S, and the hatch 3 is locked in the fully closed position.

Note that, contrary to the above embodiment, the positions of the inner rail 4 and the outer rail 5 in the direction of movement of the hatch 3 are reversed, the slide member 6 is engaged with the outer rail, and the roller 32 is engaged with the inner rail. It may be made to match.

Note that, contrary to the above embodiment, the notch 65a serving as the engaging portion may be provided on the roof 10 side, and the engaging pin 14 may be provided on the sliding member 6 side.

(Effect of the invention) According to the sliding roof hatch according to the invention, from the fully open position to the vicinity of the fully closed position, the sliding member is held in an upright running position, and the front end of the hatch is lifted, Since the inner edge moves away from the sealing material, the sliding resistance of the hatch is small, making it easy to open and close the hatch, and the slide member rotates from a running position to a low position near the fully closed position. This rotation pushes down the front end of the hatch until the entire inner edge of the hatch comes into pressure contact with the sealing material, and the hatch reaches the fully closed position, ensuring sufficient sealing performance of the hatch in the fully closed position. can. The slide member is equipped with a roller that fits into the rail, and the slide member only needs to be pivoted to the side of the front end of the hatch, so the structure is simple, the operation is smooth, and it is durable.
