Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sunroof unit that is attached to cover an opening provided in the roof of an automobile.

Conventionally, the sunroof of an automobile is made by providing an opening in a pressed roof panel, and fitting a lid thereto.
However, since the conventional sunroof is integrally built into the roof, it has the following problems:

When installing a sunroof, high precision is required for the roof because a flat lid is provided, and standard roof panels that do not require very strict precision cannot be used. Panels must be manufactured separately. In addition, in order to prevent rainwater from entering from around the sunroof, gutters are installed on the underside of the roof along the edge of the opening, and a drain hose is installed behind the interior lining of the passenger compartment to drain rainwater from the gutters to the outside of the vehicle. Piping must be installed, which increases man-hours. Furthermore, the above-mentioned vents, handles for opening and closing the sunroof, etc. protrude inside the vehicle interior, reducing the space above the vehicle interior.

The purpose of the present invention is to solve the above-mentioned problems, and the gist of the present invention to achieve this purpose is to provide a frame body installed along the entire circumference of the upper surface of the peripheral edge of the opening formed in the roof of the vehicle. a sunroof member whose one side edge is supported by the frame body, covers the upper part of the frame body, and is operated to open and close in the vertical direction about the one side edge side, and the frame body is attached to an inner wall of the sunroof member. and a drainage hole that is connected to and provided on the inside of the inner wall and whose bottom surface rests on the upper surface of the roof and that communicates with the outside of the inner wall; The sunroof unit is characterized in that at least a part of the sunroof unit comprises an outer wall forming a gap between the upper surface of the roof and the upper surface of the roof for drainage of rainwater or the like discharged from the drain hole of the trough.

Hereinafter, the present invention will be explained in detail based on an embodiment shown in the drawings.

FIG. 1 shows a schematic appearance of the upper part of an automobile equipped with an embodiment of a sunroof unit according to the present invention, and FIG. 2 shows a schematic cross-section of the sunroof unit. In the drawings, 1 is a sunroof unit, 2 is a roof of an automobile, and 3 is an opening thereof. FIGS. 3 and 4 show details of this sunroof unit in cross section.

The frame 4 of the sunroof unit 1 has a rectangular shape,
It has a double structure of an inner wall 5 and an outer wall 6 all around the circumference, and the front part is higher than the rear part. The outer wall 6a at the front is a downwardly inclined surface facing forward. A glass lid 7 is fitted into the upper part of the frame 4 as a sunroof to cover the opening. An airtight rubber seal 8 is attached to the edge of the glass lid 7 that comes into contact with the inner wall 5. Curved engagement claws 9 are attached to two places on the left and right front sides of the back surface of the glass lid. On the other hand, the front inner wall 5
An auxiliary member 11 having a groove 10 curved with the same curvature as the engaging claw 9 is fitted between the inner wall 5 and the outer wall 6a. It is inserted in 10. When the rear part of the glass lid 7 is raised, its movement is restricted by the engaging claws 9 and the grooves 10, and the glass lid 7 opens as shown by the two-dot chain line in FIGS. 2 and 3. Glass lid 7 and frame 4
A gutter 12 is formed along the entire circumference inside the inner wall 5 to receive rainwater etc. that enter through the contact portion with the inner wall 5. This gutter 12 is also inclined downward from the front part to the rear part. A drain hole 13 is provided at the bottom of the gutter 12 and communicates with the outside of the frame-shaped gutter 12. The height of the inner edge 12a of the gutter 12 is lower than the upper surface of the frame 4, and a seal rubber 14 is attached to the upper edge around the entire circumference for airtightness. When the glass lid 7 is closed, its back surface and the seal rubber 14 are in close contact.
Incidentally, the frame body 4 and the gutter 12 are integrally molded from resin, sheet metal, or the like.

In order to install the sunroof unit 1 having the above structure so as to cover the opening 3 of the roof 2 of an automobile, in this embodiment, an auxiliary frame 15 as a protrusion is attached to the roof 2 to form a peripheral edge of the roof opening. The auxiliary frame 15 includes a front flat part 15a that projects higher than the roof 2, a side slope part 15b that descends toward the rear, and an auxiliary flat plate part 15c that extends like an extension of the roof 2 at the rear. This auxiliary frame 15 may be integral or divided. Sunroof unit 1 attaches the front bottom of groove 12 to auxiliary frame 1
5, the bottom surface of the side part is placed on the sloped side part 15b, and the bottom surface of the rear part is placed on the roof 2, and each is connected with bolts 16. The bolted parts are provided with watertight means.
For example, when the frame 4 and the groove 12 are made of resin,
It is like inserting a reinforcement sheet metal 17 into the bottom of the gutter 12 and tightening it with bolts. When the sunroof unit 1 is attached to the auxiliary frame 15, a small gap is created between the lower end of the outer wall 6 of the frame 4 and the upper surface of the roof 2, and rainwater etc. discharged from the drain hole 13 of the gutter 12 is drained from this gap. It flows out of the frame 4 through the gap. Further, since the front outer wall 6a of the frame body 4 is an inclined surface, it serves as a wind deflector, and since the front part of the frame body 4 is higher than the rear part, the effect is great. In addition, in the drawing, 18
Reference numeral 19 indicates an opening/closing handle mechanism provided on the auxiliary flat plate portion 15c and the glass lid 7 for opening and closing the glass lid, and 19 indicates the interior lining of the passenger compartment.

As explained above based on one embodiment, the sunroof unit of the present invention is attached to a frame body having a grate with a drain hole so that the sunroof can be opened and closed, so that the sunroof unit is mounted on the roof like a conventional one. High precision is not required, standard roof panels can be used, and the work is easy, as it is only necessary to attach the sunroof unit to the roof. The structure is such that the troughs are located above the roof and drain rainwater onto the roof, so there is no need for a drain hose, and if the front part of the frame is made sloped so that it also serves as a deflector, no deflector is required. Therefore, the number of parts can be reduced. Furthermore, since there is no need to provide a grate or the like in the vehicle interior, the upper space of the vehicle interior can also be expanded.
