Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a lid support structure for a retractable roof for a vehicle, which is provided with a removable and tiltable lid.

Generally, this type of retractable roof for a vehicle has a roof panel 1 with a roof closure 2, as shown in FIGS. 1 and 2, for example.
The front edge 3f of the lid 3 is removably attached to the front green section 2f of the roof entrance by means of a symmetrically arranged hinge device that opens and closes the roof opening 2, and the rear edge of the lid 3 3r is attached to the roof opening rear edge 2r by a locking device L' in a tiltable and removable manner, and the lid 3 can be tilted to ventilate the vehicle interior, and the lid 3 can be removed from the roof opening 2. The roof closure 2 can be opened by removing it.

As shown in FIGS. 2 and 3, the front edge of the roof entrance 2f
The hinge housing 5 includes a hinge housing 5 having an insertion recess 4 provided therein, and a hinge tongue piece 6 that is provided on the front green portion 3f of the lid 3 to protrude toward the front of the vehicle body and is inserted into the hinge housing 5. So, the above hinge housing 5 is,
An embossing 9 that bulges out toward the front of the vehicle body is formed on the rising wall 8 of the drip frame 7, and a support panel 10 is fixed to cover the embossing 9.
It is attached by iron to the mounting hole 11 opened at 0 to prevent rainwater etc. from leaking into the vehicle interior from the mating surface of the mounting hole 11 and the hinge housing 5.

A stopper portion ridge 2 is formed at the base end of the hinge tongue piece 6, and this stopper portion turtle 2 comes into contact with a guide portion 13 disposed in front of the entrance of the hinge housing 6. It is designed to restrict the movement of the lid 3 in the longitudinal direction of the vehicle body when the lid 3 is attached, and also to position the front edge cover f of the lid 3 when the lid 3 is tilted. The tortoise 6 is a weather strip that is attached to the periphery of the lid 3 and is attached to the end flange of the seal rubber hole or frame shape that comes into elastic contact with the edge of the roof entrance 2 and is adjacent to the lower surface of the lid 8 when the lid 3 is opened. In the case of the hinge device, when the lid is tilted 3 times, the hinge tongue is simply inserted into the hinge housing flea, and the direction in which it comes out is not restricted in any way. However, when the lid 8 is tilted, the locking device L at the rear edge 3r of the lid 3 is in a half-locked state, and its supporting strength cannot be increased to any great extent.

For this reason, for example, when the vehicle is running with the lid 3 tilted, if a vehicle collides and a large impact load is applied to the lid 3 toward the rear of the vehicle body, the locking device will lock. There was a possibility that the locking state between the rear twill portion 3r of the lid 3 and the rear edge portion 2r of the roof entrance could come off, and the hinge tongue piece 6 could easily come off from inside the hinge housing S, causing the lid 3 to fly off. Therefore, as shown in FIG. 2, there is a known lid supporting lid structure in a secondary structure that is provided with a secondary locking device S, which is different from the hinge device and the locking device described above.

This secondary locking device S is provided approximately at the center of the front green part Sf of the lid, for example, and includes a lock pin attached to the lid 8 side so as to be movable in the left and right direction, and a lock pin attached to the front green part 2f of the roof exit. It is composed of a locking piece G having a locking hole (not shown) into which the lock pin Guntsuru is engaged and detached.For this purpose, this secondary lock device S
When the lid 3 is in the locked state, the front ridge 3f of the lid 3 is always engaged with the roof closing front edge 2f. Even when a load is applied, the lid 8 is effectively prevented from flying off. The front edge 3f of the lid 3 is located inside the hinge 5 provided in the green area 2f in front of the roof entrance.
Since the structure is such that the hinge blue piece 6 provided on the lid 3 is inserted and locked, when the lid 3 is installed, the hinge housing 5
In order to avoid interference with the guide part 13 provided in front of the entrance of the lid 3, the lid 3 is moved toward the front of the vehicle body, with the insertion angle of the hinge tongue piece 6 matching the inclination angle of the insertion recess 4 in the hinge housing. It is necessary to insert the hinge tongue piece 6 by pushing it out, which not only makes it complicated to align the tip of the hinge tongue piece 6 and the inlet of the hinge housing 5, but also requires skill to insert the hinge tongue piece 5. 3, making the installation operation troublesome.

In addition, in the conventional example described above, the structure required a secondary locking device S in addition to the hinge device and locking device 1 to reliably prevent the lid 3 from flying off. Not only does this result in an increase in the number of parts, but also, when attaching and detaching the heavy JD 3, the locking and locking operations of the secondary locking device S are always required, which increases the number of man-hours required for the attaching and detaching operation. There was a problem.The present invention was made based on the above points of view.
The purpose of this is to rotatably attach a movable hinge piece to a support fixed to the front edge of the roof entrance. A locking protrusion extending vertically is provided protrudingly on either one of the lid that holds the front twill part of the upper lid in the roof opening □ edge or the lid corresponding thereto. By providing a locking part in the lid and engaging the locking protrusion with the locking part at least when the lid is opened and when the lid is chilled or operated, it is possible to improve the operability of attaching the LJ lid and to An object of the present invention is to provide a lid support structure for a retractable roof for a vehicle, which eliminates the need for a locking device and reduces the number of man-hours required for attaching and detaching the lid due to a secondary locking device.

The present invention will also be described in detail below based on embodiments shown in the accompanying drawings.

In the embodiment shown in Figures 1 to 2, the lock device L that supports the rear edge Y of the lid 3 is the same as the conventional one, but the hinge device that supports the front edge 3f of the lid 3 is the same. is different from the conventional one, and this hinge device basically consists of a pair of supports 20, which are provided at symmetrical positions within the frame 7 in the roof exit front twill section 2f, and are fixed to the frame 7; A movable hinge piece 21 is rotatably attached to the holder.

In this embodiment, as shown in FIG. 5, the support body 20 includes a pair of upper and lower metal plates 22, 23, and a pair disposed on both sides of these plates 22, 23 in the longitudinal direction. It is composed of an elastic body 24 which is attached by baking or the like in between.

A locking protrusion 25 is attached to the rear side of the lower plate 23 at an approximately central portion thereof in the longitudinal direction, and the locking protrusion 25 is connected to the upper plate 22.
It extends upward in close proximity to a notch 26 provided on the rear side of the substantially center in the longitudinal direction, and its tip is located slightly below the general surface of the roof panel 1. Further, as shown in FIG. 5, the movable hinge pieces 21' are integrally formed of synthetic resin or the like, and include a flat base plate 27, and a pair of movable hinge pieces 21' provided on both sides of the base end of the base plate 27. A hook portion 28 having a fishing shape bent inward, and a connecting portion 30 provided on the lower surface of the protrusion portion 29 of the hook portion 28 and connected to the upper plate 22.
It is made up of.

The hook portion 28 is set such that the gap between the projecting piece 29 and the base plate 27 approximately corresponds to the thickness of the lid 3. A cutout end 31 formed on the front edge is inserted and locked. Further, the connecting portion 3 consists of a pair of engaging pieces 30a and 30b bent inward from the proximal and distal ends of the protruding piece 29 of the hook portion 28, and these engagement pieces The front and rear edges of the upper plate 22 are tightly held by the pieces 30a and 30b. This movable hinge piece 21 is connected to the connecting portion 30.
By being integrally connected to the support body 201 via the elastic body 24, the elastic body 24 is rotatably attached to the support body 201 with respect to the support body 201 as a virtual center of rotation. Furthermore, near the rear of the notch end 31 formed on the front edge 3f of the lid 3, as shown in FIGS. 4 and 6, the locking protrusion 25 is provided.
A locking portion 32 consisting of a hole into which the tip of the movable hinge piece 21 can be inserted is formed, and a recess 33 is provided on the back surface of the base plate 27 of the movable hinge piece 21 at a location corresponding to the locking portion 32. The protrusion 25 and the movable hinge piece 21 are prevented from interfering with each other. Incidentally, a female screw portion (not shown) is provided approximately at the center of the lower plate 23 and on the lower surface of the locking protrusion 25, so that the support body 20 can be disposed at a predetermined position on the bottom wall of the frame 7, and The support body 20 is positioned and fixed by screwing a bolt 34 through a sealing packing 40 into the female threaded portion through an opened mounting hole (not shown). In addition, a rubber sheet (not shown) is attached to the entire back surface of the movable hinge piece 21 including the inside of the hook portion 28, so that rainwater etc. can be absorbed from the joint part of the movable hinge piece 21 and the lid 3. There are no defects that could leak into the passenger compartment. Therefore, in this embodiment, when attaching the lid 3 to the roof opening 2, as shown in FIG. Hold the lid 3 in a forward position so as not to interfere with the protrusion 25 at the top, move the lid 3 toward the hook portion 28 of the movable hinge piece 21, and insert the cutout end 31 of the lid 3 into the hook portion 28. It is only necessary to lock them against each other.

Thereby, the front edge portion 3f of the lid 3 is held within the hook portion 28, and the front twill portion 3f of the lid 3 is positioned. Next, the lid 3 is tilted forward and rotated downward in the direction of arrow A in FIG. At this time, the sub-retention projection 2 provided on the front edge 2f of the roof entrance
As shown in FIG. 7, the lid 3 is locked to the locking portion 32 of the lid 3, and the movement of the lid 3 in the left-right and front-back directions is automatically restricted. Furthermore, the shaft pin 36 of the locking device L provided on the front twill portion 3r of the lid 3 shown in FIG.
When the lid 3 is pushed into the receiving part 36 provided on the rear edge 3r of the roof opening, and then the handle 37 is rotated toward the rear of the vehicle, the locking device L is locked. When the lid 3 is completely engaged with the rear green part 2r of the roof entrance, the installation work of the lid 3 is completed.On the other hand, when the lid 3 is removed from the roof opening 2, as shown in FIG. Part 3r
After unlocking the locking device L installed in the lid 3 and rotating the lid 3 upward to a predetermined position, the lid 3 is raised upward to the rear of the vehicle body and released from the hook portion 28 of the movable hinge piece 21. good.

That is, when the lid 3 is rotated upward to a predetermined position,
Since the engagement state between the locking protrusion 25 and the locking portion 32 is automatically released, and there is no restriction on the direction in which the lid 3 comes off, the lid 3 can be easily removed. Also L
In this embodiment, as shown by the two-dot chain line in Fig.
When the lid 3 is fully tilted, the locking protrusion 2 is engaged with the locking protrusion 2.

For example, even if a vehicle collides and an impact vehicle hits the lid 3 toward the rear of the vehicle, the front green part of the lid 3 will remain fully engaged. There is no dust caused by the lid 3 coming off and scattering.Furthermore, in the above embodiment, in order to rotatably support the movable hinge piece 21, there is no elastic body 2 between the pair of upper and lower plates 22 and 28. A support body 28 made of a turtle ball is used.
Since the elastic body 24 is the virtual center of rotation, there is no need to pivot the movable hinge piece 28, and the movable hinge can be smoothly rotated without worrying about looseness between the rut pin and its receiving part. It is possible to operate it in rotation. Therefore, the tilting of the lid 8 becomes extremely stable.Also, in the above embodiment, a pair of movable hinges are provided at symmetrical positions, but the front edge of the roof entrance 2 is Install one roughly in the center ~ or open the roof □
It may be provided over the entire front Ayabe Takaf area.

Also, in the above embodiment, two movable hinge pieces are supported by two supports using an elastic body 4, but they are not necessarily limited to this. Also, the support body can be constructed with just a fixed bracket.
The movable hinge piece 2 may be rotatably attached via the fixed bracket 881 and the hinge pin. In addition~
In this case as well, it is desirable to bias the movable hinge with a spring or the like so that the single fin arm of the movable hinge is free and stands up as shown in the diagram. Furthermore, in the above embodiment, the locking protrusion 2
Although the box is provided integrally with the support 2, it may be placed in a desired location away from the support 2, such as in the 2nd year of the crab line in front of Sekiguchi or on the side line of the roof opening. In this case, the locking part 8 on the lid 3 side may be provided at a position corresponding to the locking protrusion 2. Also, the locking part 32 does not necessarily have to be a hole, but may be a recess or a projection. In addition, ``in the above embodiment, the locking protrusion is provided on the vehicle body side, and the locking portion 32 is provided on the T-lid 3 side.'' Even if these positional relationships are reversed, Of course it's a good thing. As explained above, according to the lid support horizontal structure of the retractable roof for vehicles according to the present invention, the movable hinge piece can be rotatably attached to the support fixed to the green part in front of the opening of the roof. A hook-shaped hook part that holds the front twill part of the iJ lid is formed at the base end of the piece, so when the lid is installed, the front edge of the lid can be held in the hook part with the lid in the front position. By doing so, the troublesome mounting operation of inserting and locking the hinge blue piece into the hinge housing as in the conventional case is eliminated, and the operability of mounting the lid is greatly improved.

Furthermore, either the roof opening green portion or the lid corresponding thereto is provided with a locking protrusion extending in the vertical direction, and the other side is provided with a locking portion that is fixed at least when the lid is opened. When the lid is tilted, the locking protrusion is aligned with the locking part, so when the lid is opened or tilted, the position of the lid is reliably regulated in the longitudinal direction of the vehicle body. Even if a vehicle collides while the lid is tilted, or if an impact load is applied to the lid, there will be no chance of the lid flying off.Therefore, there is no need to provide a separate secondary locking device as in the past. Not only can the number of parts be reduced by that amount, but also the number of man-hours required for attaching and detaching the L-lid can be reduced since it is no longer necessary to unlock and lock the secondary lock device when attaching and detaching the L-lid.
