DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hinge structure for a retractable roof for a vehicle, in particular, a hinge structure in which a removable and tiltable lid is operably attached to a leaf panel, and a locking mechanism is incorporated to prevent it from coming off when attached. This invention relates to a hinge device for a retractable roof for a vehicle with a built-in vehicle.

Some vehicles are equipped with a retractable roof to ventilate the interior of the vehicle while increasing the sense of freedom for the occupants. An example of such a retractable roof is shown in FIG. This involves opening a roof opening 2 in the roof panel 1, engaging the front edge 2f of the roof opening 2 with the front edge of the lid 3 in a detachable manner, and locking the rear edge of the lid 3 with a locking device L. The lid 3 is mounted so that it can be tilted to ventilate the vehicle interior.
can be removed from the roof opening 2 to open the roof opening 2. A hinge device is used to engage the front edge of the lid 3 with the front edge 2f of the roof opening 2. Conventional examples of such a hinge device include those shown in FIGS. 2 and 3, for example. There is.

This hinge device H is provided in a pair at symmetrical positions at the junction between the front edge 2f of the roof opening 2 and the front edge of the lid 3, and includes a hinge house 4 formed at the front edge 2f of the roof opening 2, It consists of a hinge tongue piece 5 provided on the front edge of a lid 3 corresponding to the hinge housing 4 and fitted into the hinge house 4. The hinge housing 4 has a roof opening front edge 2f.
A part of the frame 7 is formed with an embossment 8 toward the front side of the vehicle body, and a support panel 9 is attached between the embossment 8 and the roof panel 1. This support panel 9 forms a storage space and
A housing body 12 made of synthetic resin and having an insertion recess 11 is fitted into the mounting hole 10. This causes frame 7
Since the mounting hole 10 is no longer provided in the mounting hole 10, it is possible to prevent rainwater from entering the vehicle interior through the mounting hole 10. The other hinge tongue piece 5
has a base end fixed to the front edge of the lid 3 with a screw 13, and a stopper part 14 extending from the base end toward the front side of the vehicle body, and a stopper part 14 extending forward from the stopper part 14. It has a fitting part 15. The fitting portion 15 can be fitted into the insertion recess 11 of the hinge housing 4.
When this insertion is performed, it is possible to rotate a predetermined amount in the vertical direction around the spherical tip portion 16;
The stopper part 14 corresponds to a guide part 17 disposed in front of the entrance of the hinge housing 4, and restricts the movement of the lid 3 in the longitudinal direction of the vehicle body when the lid 3 is installed. In addition to preventing vibration between the lid 3 and the hinge tongue 5, the guide portion 17
The front edge of the lid 3 is positioned by sliding on the top.

Further, as is clear from FIG. 2, an auxiliary secondary lock device S is installed between the pair of hinge devices H, separate from the lock device L. This secondary locking device consists of a locking pin 18 provided approximately at the center of the front edge of the lid 3, and an engaging member provided at a position corresponding to the locking pin 18 on the front edge 2f of the roof opening. After fitting into the roof opening 2, the lid 3 is fixed to the vehicle body in the same way as the lock device L by locking the lock pin 18 with the engaging member. In the figure, reference numeral 19 is a seal rubber that maintains a seal between the lid 3 and the front edge 2f of the roof opening, and 20 is a weather strip that seals between the frame 7 and the lid 3.

However, in the case of such a conventional hinge device for a retractable roof for a vehicle, the front edge of the roof opening 2
Since the hinge tongue piece 5 provided at the front edge of the lid 3 is inserted and locked into the hinge housing 4 provided at the front edge of the lid 3, when trying to attach the lid 3,
After aligning the tip of the hinge tongue piece 5 with the entrance of the hinge housing 4 while avoiding interference between the guide portion 17 provided in front of the entrance of the hinge housing 4 and the hinge tongue piece 5, the insertion angle of the hinge tongue piece 5 is adjusted. It was necessary to match the angle of inclination of the insertion recess 11 in the hinge housing 4 and insert the hinge tongue piece 5 into the hinge housing 4 in this state. Therefore, alignment between the tip of the hinge tongue piece 5 and the entrance of the hinge housing 4 becomes complicated, and the hinge tongue piece 5
The insertion work required skill and made the operation of attaching the lid 3 troublesome. In addition, in the above conventional example, when the lid 3 is chilled, the hinge tongue piece 5 is simply inserted into the hinge housing 4, and an impact load is applied to the lid 3 in the event of a vehicle collision, for example. When the lid 3 falls off, the hinge tongue piece 5 is designed to be relatively easily detached from the inside of the hinge housing 4. Therefore, in order to reliably prevent the lid 3 from falling off, it is necessary to install the hinge tongue piece 5 separately from the hinge device H. A secondary locking device S is always required, which not only increases the number of parts, but also requires releasing and locking the secondary locking device S when attaching and detaching the lid 3, resulting in the problem of increasing the number of operating means. .

The present invention has been made in view of the above problems, and its purpose is to connect a hinge device to a movable piece attached to the front edge of the lid and a hinge device attached to the front edge of the roof opening corresponding to the movable piece. Either the movable piece or the fixed piece consists of a base plate and a hinge pin that is attached to the base plate so that it can move forward and backward, and a hinge pin that bulges out along the axial direction of the hinge pin on the vertical wall of the base plate. The other has a protrusion that extends perpendicularly to the axis of the hinge pin, a pin insertion hole formed in the protrusion into which the hinge pin is inserted, and a side wall of the protrusion. A guide member is provided on the lid and guides the bulge to align the hinge pin with the pin insertion hole, thereby improving operability of attaching the lid and serving both as a hinge device and a secondary lock device. An object of the present invention is to provide a hinge device for a retractable roof for a vehicle, which enables a reduction in the number of parts.
