2. Description of the Related Art Conventionally, as a frame structure of a sunroof device for an automobile or the like, there is one disclosed in Japanese Utility Model Publication No. 7-46569. This conventional frame structure is composed of a vertical frame made of extruded aluminum material, a horizontal frame made of hard thin metal pirate, and a corner drip made of resin material. Can be contributed to.

The frame structure disclosed in Japanese Patent Application Laid-Open No. 7-149153 is composed of a vertical frame made of an aluminum material, a horizontal frame made of a resin material and having a corner portion extending to the side, and a lower surface of the horizontal frame. In addition, a guide plate made of a metal material is fixed, so that the thickness of the device itself can be reduced and the device can be made relatively inexpensive.

[0004]

In the prior art, since the connection between the horizontal frame and the vertical frame is made only by the corner drip made of resin, the object is achieved if the frame structure is made flexible. However, when a rigid structure is used, the strength is insufficient if only the resin corner drip is connected.

It is conceivable to form the corner drip with a metal such as an aluminum alloy with high strength. However, since the shape is complicated, molding costs are higher than those made of resin. Not suitable. Also, the cable is inserted from the drive mechanism provided in the horizontal frame to the vertical frame, but since the corner drip is in the middle of insertion and does not guide the cable, a cable tube must be separately provided, and the structure is It is complicated and cumbersome to assemble.

In the prior art described later, the cable can be inserted from the horizontal frame to the vertical frame. However, since the horizontal frame member is formed of resin, the corner drip can be provided integrally, but the strength is reduced. In order to maintain it, a plate member made of a metal material that is fixed to the lower surface of the horizontal frame across the two vertical frames is required, and the large-sized member has a double structure.

[0007] Therefore, a mold must be made for each vehicle type, and the size is large, so that the cost is extremely high and the structure is not suitable for carryover. An important object of the present invention is to provide a frame structure of a sunroof device which can have a high rigidity frame structure and can be adapted to each vehicle model at a low cost while having a structure in which a cable is inserted from a horizontal frame to a vertical frame. To provide.

Another object of the present invention is to provide a frame structure of a sunroof device which can smoothly slide while suppressing abrasion of a cable at a corner drip. Another object of the present invention is to provide a frame structure of a sunroof device that can prevent water scattering at a corner drip by a cover member. Another object of the present invention is to provide a frame structure of a sunroof device that can prevent water from flowing from a vertical frame to a horizontal frame.

The left and right ends of the horizontal frame 6 and the ends of the left and right vertical frames 7 are arranged in a non-overlapped state close to each other with the extruded material being substantially linear. A corner drip 9 made of an injection-moldable material having a cable insertion portion 40 for draining water flowing from the inside, and at least more rigid than the corner drip 9 Is that linked by being sandwiched between the bar member 10.

As a result, the rigidity of the frame 5 is increased while the cable 13 is continuously inserted from the horizontal frame 6 to the vertical frame 7, so that the structure can be adapted to each vehicle type at low cost. Second solution for solving the problem in the present invention
The concrete means of the present invention is such that, in addition to the first concrete means, a cable insertion portion 41 is formed in the cover member 10, and the cable insertion portion 41 is connected to the cable insertion portion 40 of the corner drip 9.
The cover member 10 is joined to the corner drip 9 so that the cover member 10 has a substantially circular shape.

As a result, the insertion of the cable 13 through the corner drip 9 ensures smooth sliding of the cable 13 with less wear. A third specific means for solving the problem in the present invention is that, in addition to the first or second specific means, the cover member 10 is provided on a water receiving portion 34 formed on a corner drip 9 for receiving inflow water. And it is possible to prevent water scattering.

As a result, water scattering at the corner drip 9 is prevented by the cover member 10. A fourth specific means for solving the problem in the present invention is that, in addition to any one of the first to third specific means, a horizontal frame 6 is provided at an inner surface of the corner drip 9 at a position where the flowing water of the vertical frame 7 extends. That is, a flow restricting unit 30 for preventing the flow of water into the water is provided.

The left and right ends of the horizontal frame 6 of the frame 5 and the ends of the left and right vertical frames 7 are arranged in a non-overlapped state and are close to each other, and the two adjacent ends are covered with the corner drip 9 and the corner drip 9. It is connected with the cover member 10. The corner drip 9 and the cover member 10 can be formed of a synthetic resin or metal or the like. Here, the corner drip 9 is formed by injection molding of a resin, and the cover member 10 is formed by pressing or casting a metal plate. Thus, the cover member 10 is formed of a material that is more rigid than at least the corner drip 9.

The corner drip 9 is fixed by applying the end of the horizontal frame 6 to the upper end of the joint 32 at one end thereof via a joining material 31, and fixing the vertical frame 7 to the upper end of the joint 33 at the other end. Is fixed by applying a front end portion of the cover member 10 via a bonding material 31, and a cover member 10 is applied and fixed to the upper side of the front end portion by using bolts or rivets other than screws. .

The fixing of the cover member 10 is preferably performed in a state where the horizontal frame 6 and the vertical frame 7 are connected to the corner drip 9, but the horizontal frame 6 is sandwiched between the corner drip 9 and the cover member 10. In this state, they may be fastened together with screws, and then they may be fastened together with the vertical frame 7 sandwiched therebetween. Joints 32, 3 at both ends of the corner drip 9
3, one or more grooves intersecting with each longitudinal direction of the horizontal frame 6 and the vertical frame 7 are formed and have an uneven shape, and the bonding material 31 is injected into the grooves more than the groove volume. The horizontal frame 6 and the vertical frame 7 are applied, and over the entire area of the mating surface between them and the joints 32 and 33,
The joining material 31 is interposed.

The sealing material 31 is preferably a sealing material such as butyl, but other sealing materials or adhesives can be used, and the sealing between the corner drip 9 and the horizontal frame 6 and the vertical frame 7 is ensured. It is good if you can. The cable 13 pushed and pulled by the drive mechanism 14 extends from the cable insertion portion 6B of the horizontal frame 6 to the cable insertion portion 7C of the vertical frame 7, so that the cable 13 is also inserted into the corner drip 9 and the cover member 10. The cable 13 in which the corner insertion portions 40 and 41 are formed and
Even so, it can be guided smoothly with low resistance.

Each of the cable corner insertion portions 40 and 41 has a semicircular cross section, and has a corner drip 9 and a cover member 10.
Are formed on each other, and when they are joined to each other, the cross-sectional shape of the insertion portion is substantially circular. As shown in FIGS. 1 and 9, the left and right sides of the horizontal frame 6 have a state in which the cables 13 are inserted in parallel and a state in which the cables 13 intersect with each other. Have different shapes.

The corner drip 9 has a concave water receiving portion 34 for receiving water flowing from the front gutter portion 6A of the horizontal frame 6 and the vertical gutter portion 7A of the vertical frame 7, and the water receiving portion 34 has A drain port 39 is formed so as to be communicated, and can be drained to the outside via a drain hose. The drain port 39 is located inside the outer surface of the corner drip 9 and is protected by the outer peripheral portion of the cover member 10 so as to be hardly damaged.

A tongue-shaped flow restricting portion 30 is formed on the inner surface of the water receiving portion 34 of the corner drip 9 at a position where the flowing water of the vertical frame 7 extends. The flow restricting portion 30 is configured such that the water flowing from the vertical gutter portion 7A of the vertical frame 7 into the water receiving portion 34 flows along the arc-shaped outer wall 34B of the water receiving portion 34, and the front gutter portion of the horizontal frame 6 This is for preventing an attempt to go around 6A.

The rapid flowing water into the water receiving portion 34 is large when the vehicle is suddenly braked. Therefore, the flowing regulating portion 30 is formed at the flowing water extending position of the vertical frame 7. It may be formed at the extended position, or both may be formed, or one may be formed at a position that combines both. The cover member 10 is formed in an arc shape in a plan view, covers a substantially outer half of the corner drip 9, and connects the ends of the horizontal frame 6 and the vertical frame 7 with the corner drip 9 at both ends.

As shown in FIGS. 1 and 7, the cover member 10 protrudes and covers the water receiving portion 34 of the corner drip 9 so that the water flowing into the water receiving portion 34 is scattered. Is prevented from doing so. The cover member 10 can be formed in a shape that covers the entire surface of the corner drip 9. However, even if the cover member 10 does not cover the water receiving portion 34, the corner drip 9 can be reinforced.

The joining end of the vertical gutter 7A of the vertical frame 7 projects from the inner surface of the wall 34A of the water receiving portion 34 of the corner drip 9 into the water receiving portion 34 to form a projecting end 35. I have. The protruding end 35 forms a pocket 36 between the lower surface and the inner surface of the wall 34A of the water receiving portion 34 by the amount of the protrusion. Due to the presence of the pocket portion 36, even if the joining material 31 joining the front end of the vertical frame 7 and the joining portion 33 of the corner drip 9 leaks to the water receiving portion 34 side, the joining material 31 goes out to the pocket portion 36. This can prevent the protrusion from protruding above the protruding end 35. Further, a larger amount of the bonding material 31 can be filled than before, and the sealing effect can be enhanced.

The protruding end portion 35 is inclined downward into the water receiving portion 34 to prevent water from accumulating on the joint side end portion of the vertical frame 7 due to surface tension. The protruding end 35 may be bent in an arc shape and inclined downward.
Further, the lower end edge of the protruding end 35 is inclined in the left-right direction (the left and right ends are inclined so as to be more forward than the other end), so that water easily gathers at one end. The lower end edge of the protruding end 35 can be three-dimensionally inclined from the left and right ends to the other end from the lower front to the upper rear.

Further, one or more (two in this embodiment) notches 37 are formed in the protruding end portion 35 at an intermediate position in the left-right direction, so that surface tension is prevented to cut water in the left-right direction. Well done. These shapes of the projecting end 35 collectively make the drainage at the joint-side end of the vertical frame 7 good. Note that the present invention is not limited to the above embodiment, and can be variously modified. For example, the cover member 10 may have a shape that covers the entire upper surface of the water receiving portion 34, or may form the flow restricting portion 30. Further, the joining side end of the vertical gutter portion 6A of the horizontal frame 6 may be formed in the same shape as the protruding end portion 35 so as to improve drainage.
