Description

[Detailed description of the invention] The present invention relates to a device that reliably prevents the movable roof from being pulled out in the opening/closing roof portion of the roof of a vehicle such as an automobile, which has an opening structure that can be freely opened and closed by the movable roof. .

A retractable roof device that provides an opening above the driver's cab on the roof of a vehicle such as a passenger car and covers the opening with a movable roof that can be freely opened and closed is known as a so-called sunroof yo. be.

The movable roof generally slides horizontally or
Alternatively, a sliding roof type is used in which one end is tilted and then slid horizontally.

At this time, the movable roof is slid on both symmetrical sides along guides provided on the roof. For this purpose, sliding edges formed on both symmetrical sides are slidably engaged in the guides to ensure smooth movement. However, on a relatively narrow automobile roof, the amount of engagement between the guide and the sliding edge is relatively shallow due to manufacturing and assembly reasons. When an upward external force is applied, the roof easily bends and deforms due to the fact that most movable roofs are hollow and are designed to be lightweight, which often causes problems such as the slide edge separating from the guide. There is a problem.

In order to solve these problems, the present invention is designed to provide a pull-out stop to reliably prevent the movable roof from coming off.The main feature of this invention is that the movable roof is provided with a stopper on both the left and right sides of the opening in the vehicle roof. A pair of left and right guides are provided on the vehicle roof in the front and back direction, and a movable roof is provided at both left and right ends so as to be slidable back and forth by the pair of left and right guides, and which covers an opening so as to be openable and closable. In a retractable roof for a vehicle in which an opening/closing lock mechanism is provided on the side of the movable roof to lock the movable roof open/close by releasably engaging with a locking hole on the roof side, the upper end side of the inner periphery of the left and right sides of the opening. A pull-out locking groove that opens downward is provided in the front-rear direction, and a pull-out locking part that can be engaged with the locking groove from below is provided in order to prevent the movable roof from coming off upward. It is provided on the opening/closing locking mechanism side with a gap between it and the locking groove, and the locking part is provided to protrude laterally from the opening/closing locking mechanism in correspondence with the lock bar of the opening/closing locking mechanism vertically. be.

The present invention will be described in detail below with reference to the embodiments shown in the drawings. Figure 1 shows the appearance of the main part of an example of a retractable roof equipped with a movable roof embodying the present invention, and Figure 2 shows the appearance of the main part of an example of a retractable roof equipped with a movable roof that implements the present invention. 3 shows an enlarged cross section of the main parts of each roof and roof-related structure side along line B, and FIG. 3 shows the main parts of the cross section taken along line C-C in FIG. 2 is a roof of a vehicle such as an automobile, and 2 indicates a guide for a sliding roof 3, which is an example of a movable roof formed integrally with or separately from the roof 1, and is approximately U-shaped in the illustrated example. The sliding roof 3 can be opened and closed along the guided guide 2, and the roof 3 is shown to be openable and closed. In the case of an automobile, the opening 4 is generally provided in a portion of the roof above the driver's cabin of the vehicle. The purpose of this invention is to prevent the roof 3 from being pulled out at the roof opening 4, and since the present invention is not concerned with the detailed structure of the sliding roof 3 or the opening 4, these points will not be covered in its general form. Although only an example is shown schematically, Fig. 2 (I
), (II), the sliding roof 3 that covers the approximately square opening 4 in a freely openable and closable manner has a hollow 2 It is a heavy structure and has reinforcing ribs 3as on the lower surface facing the opening 4.
A sliding edge 6, which is provided with a lining material 16 and the like and is formed in an overhanging manner on the entire periphery of the roof 3, is placed on two symmetrical sides of the guide 2 provided on the roof 1, and its two corresponding sides are connected to the weather strip 5. The opening 4 is surrounded by an opening periphery 14 formed by appropriately bending the opening end of the roof 1 inward, and is fixed to the opening periphery 14 with bolts 12 nuts 13 or the like. A reinforcing roof frame 10 is provided in parallel on the back side of the roof 1, and a roof lining material 11 is stretched over the roof frame 10.
A sealing material 15 having a flocked surface or the like is attached to the top surface corresponding to the lower surface of the sliding roof 3 of No. 4.

At this time, the amount of engagement between the guide 2 and the sliding edge 6 is generally only relatively shallow, which is unavoidable from the standpoint of manufacturing and assembly. When an external force is applied, the roof 3 is likely to bend and deform upward, and therefore there is a strong possibility that the engaged edges 6.6 on both sides will come out from within the guide 2.

The present invention provides such a retractable roof, as shown in FIG. 3, although the sliding roof 3 is omitted in the illustration, as is known, the bottom side of the roof 3 shown in the second diagram has a lining material 16. On one side of the opening/closing lock mechanism 18 installed,
An upward locking pawl or a wall-shaped pullout locking part 31 is attached in a protruding manner, and this locking part 31 is split into the top inner surface of the opening periphery 14 surrounding the opening 4 in the roof 1. Stop groove 3
2 is provided with a slight gap so that it can be locked from below to prevent the roof 3 from coming off upwards, and 33 is a lock bar in the lock mechanism 18, which locks the locking portion 3.
The bar 33 protrudes laterally from the locking mechanism 18 corresponding to the upper and lower sides of the bar 1, and in the illustrated example, the same bar 33 is also removably engaged with a locking hole (elongated hole such as a square hole) 34 provided in the opening periphery 14. has been done.

In this example, the opening periphery 14 is formed as an independent member separate from the roof 1, and is fixed with bolts 12 nuts 13 to the reinforcing roof frame 10 on which the lining material on the roof 1 side is stretched. may be of an integral structure in which one end facing the opening 4 of the roof 1 is bent, and of course the opening periphery 1
The cross-sectional shape of 4 itself can be freely designed except for the locking groove 32.

An example of the details of the opening/closing lock mechanism 18 is shown in FIG.
As is clear from the side views of I) to (I[[), the mechanism 18 includes a box 35 attached to the bottom of the sliding roof 3, and is slidably housed within the box 35, with one end protruding outside the box. a cam 39 whose one end is pivotally supported in a box 35 via a pivot 36 and a spring 37, and which can be connected to the middle of the lock par 33 by a connecting shaft 38; The end of the operating lever 42 is connected to the pivot 40 by the elongated hole 41, so that the operating lever 42 is connected to the box 35.
By pushing the cam 39 to the side, the cam 39 rotates counterclockwise through the engagement of the pivot shaft 41 with the pivot shaft 36 as a fulcrum against the spring 37, and the locking member 33 is moved back along with it via the connecting shaft 38. , the bar 33 is disengaged from the locking hole 34 of the opening periphery 14 to enable the sliding roof 3 to slide open and close, and is normally locked to prevent the roof 3 from moving. The upward locking portion 31 is integrally protruded from one side of the box 35, or a separate locking portion 31 is attached, and the box 35 has a generally oval shape.

The locking groove 32 in the opening periphery 14 can be formed into a downward opening shape by horizontally bending the upper end of the opening periphery as shown in the figure, but this can be done by attaching an inverted U-shaped locking groove. Good too.

According to the removal prevention mechanism of the present invention, the removal prevention locking part 31 engages from below with the removal prevention locking groove 32 provided in the front and back direction on the upper end side of the inner periphery of the left and right sides of the opening 4. , movable roof 3
Since it is designed to prevent the movable roof 3 from coming off upward, even if an upward external force (direction X in Figure 2) is applied to the movable roof 3,
The movable roof 3 does not come off the guide 2, and it is possible to prevent the movable roof 3 from coming off due to bending deformation or the like.

Also, although the guide 2 is installed on the vehicle roof 1,
Separately, a locking groove 32 is provided on the upper end side of the inner circumference of the opening 4 to separate the guide 2 and the locking groove 32, and a locking portion 31 is provided in the opening/closing lock mechanism 18 provided on the movable roof 3. Because of this, there is no need to make the vehicle roof 1 unnecessarily thick, and it can be made compact and can be incorporated even in a narrow space.

The locking part 31 is provided with a gap below the locking groove 32, and is designed to engage with the movable roof 3 to prevent it from coming off when it is lifted, so that when the movable roof 3 is opened or closed, However, the movable roof 3 can be opened and closed smoothly without the locking portion 31 acting as resistance.

The locking portion 31 projects laterally in vertical correspondence with the locking hole 33 of the locking mechanism 18, and is engaged by the locking hole 34 of the locking hole 34 and the locking groove 32 of the locking portion 31. The movable roof 3 can be prevented from being pulled out in a double manner, and is excellent in preventing the movable roof 3 from being pulled out from the guide 2.
