Each element ψ) is moved to close the roof surface with each element (b).

(Problems to be Solved by the Invention) In the conventional retractable roof structure described above, each roof element is configured so that only the supporting points at both ends move independently, and each element is a heavy structure. becomes. Furthermore, since a plurality of running rails are laid across the lower bridge in the lateral direction, a large rail space is required.

The present invention has been proposed in view of the problems of the prior art, and allows for easy storage of roof elements when the roof surface is open, a large opening ratio of the roof surface, and space for the driving device of the element including the rail. The object of the present invention is to provide a retractable roof structure that can minimize the amount of damage.

(Means for Solving the Problems) In order to achieve the above object, the retractable roof structure according to the present invention includes a top panel, a vertical structural panel connected to the front edge of the top panel, and both panels. The roof consists of a plurality of roof elements arranged successively in the front and back direction formed in the cross section of the mold, and each of the same elements A top guide rail extending in the front-rear direction and a guide roller running on the guide rail on the top panel of the adjacent element are mounted on the top panel, and a unit disposed on the lower frame is mounted on the vertical panel. It is constructed by mounting wheels that run on one running rail and a drive device for the wheels.

(Function) Since the present invention is configured as described above, each of the above-mentioned "
A drive device drives wheels mounted on the vertical panel of the roof element having a shaped cross section, and moves the wheels along the running rails laid on the lower frame, and also drives the guide rollers mounted on the upper panel. , by moving the adjacent roof elements along the top guide rails mounted on the top panels of the adjacent roof elements, the roof elements are sequentially overlapped with the adjacent roof elements, and the roof elements are stored on the support frame side and the roof surface of the structure is moved. to open.

Further, the roof surface is closed by sequentially moving each of the roof elements in the stored state on the traveling rail in a direction opposite to the previous direction.

The side portions of the element are stiffened by the stiffening surface panels disposed across the left and right end portions of the top panel and vertical surface panel of the roof element, and the running force of the driving wheels is is transmitted to the top surface of the panel in the mold section,
This prevents the panel from twisting when running.

Also, out-of-plane forces on the longitudinal panels of the roof element are resisted by the top panel.

Furthermore, when the roof element is opened and closed, the guide roller mounted on the top panel slides along the top guide rail of the top panel of the adjacent roof element.
The load on the top panel of each roof element can be transferred to the vertical panel of the adjacent element through the vertical panel of that element and the top panel of the adjacent roof element, such that said top panel is This will reduce stress and deflection.

(Example) The present invention will be described below with reference to the illustrated embodiments.

(2) is a main roof composed of a curved roof, around which a support frame (81IO) is arranged, so that the curved roof composed of a plurality of roof elements can be opened and closed in both directions, centering on the top of the roof. (See Figures 12 to 14) (a) is a roof element in which a vertical structural panel (2) is connected from the front edge of the top panel (1), and each panel (1)
A stiffening surface panel (3) is integrally provided over the left and right end portions of (2).

At the lower end of the vertical panel (2), there are running wheels (5) running on a single arch-shaped running rail (4) laid in the arena and extending in the front-rear direction;
The drive device (6) of 5) is installed.

A top guide rail (7) extending in the longitudinal direction is mounted on the top panel (1), and a top guide rail (7) on the top panel (1) of the adjacent roof element (a) is mounted on the rear end. A guide roller (8) is mounted on the top.

The above-mentioned roof tiles (a) are arranged in succession in the front-rear direction so as to be movable on a common running rail (4) for the left and right cars.

When the roof surface is opened, as shown in FIG. If the roof surface is to be closed due to the condition, first drive the running wheels (5) of the leading roof element (a+) through the drive device (6 wheels), and move the same element (a,) onto the running rail (4). The guide roller (8) mounted on the top panel (1) of the roof element (a) moves along the top panel (a2) of the next roof element (a2). 1) Rolling along on the upper top guide rail (7), said element (al) moves smoothly.

(See Figure 9) Next, roof elements (a,) (a2
) along the traveling rail (4) (see Figure 10), and finally the trailing roof element (a=) is moved together with each of the roof elements (a, ) (at);
The roof surface is closed together with each roof element (not shown) on the opposite side. (Refer to Fig. 11) Next, when opening the roof surface, each roof element (a,) (a-) (as) is moved from Fig. 11 to Fig. 10 and Fig. 9 by reversing the previous operation. After passing through the state shown in Fig. 8, it is stored in the support frame (O side) as shown in Fig. 8.

According to the embodiment, a roof element with a shaped cross-section (a
), which form the main body of the top panel (1) and the vertical panel (2).
The stiffening surface panels (3
), when the roof is opened and closed, the vertical panel (2)
The driving force from the driving wheels (5) mounted on the roof is transmitted to the top surface of the "shaped cross-sectional roof elmmen" (a),
``This prevents the panels in the mold cross section from twisting during travel.

Therefore, even when the roof element (a) runs on the arc-shaped running rail (4), the stiffening surface panel (3 ). (See Figure 1) In addition, the horizontal force generated when opening and closing the vertical panel (2), the wind, and the component force in the tangential direction of the running rail due to its own weight when traveling on the arc-shaped running rail (4), etc. Out-of-plane forces are resisted by the top panel (1) of said element (a).

In addition, a guide roller (8) is mounted on the top panel (1) so that it slides on the top guide rail (7) on the top panel (1) of the next roof element. As shown by arrows X and Y in the figure, the load on the top panel (1) of the roof element (al) is
Vertical panel (2) of a) and the next roof elm) (
az) through the top panel (1) of the same element (a2
) can be flowed onto the vertical structure panel (2). This allows the top panel (1) of said element (a,) to be supported by both ends, reducing stress and deflection.

Furthermore, the roof elm) (a,) (a-) (as
) is configured to move on a single running rail (4), so a running rail is provided for each element, and compared to the conventional example in which the same rails are arranged side by side, it is possible to move on a single running rail (4). The drive space does not overlap in the lateral direction, and the minimum space is required.

Furthermore, by adopting the roof element (a) of the shaped section type panel, the thickness of the storage space (Sl) when the element (a) overlaps is considerably reduced compared to the conventional example. (Fig. 15 and (See FIG. 18) (Effects of the Invention) According to the present invention, as described above, the roof elements, which are successively arranged so as to be movable in the roof opening direction along the running rail, are connected to the top panel. By creating a panel with a shaped cross-section, consisting of a vertical structural panel and a stiffening panel placed across the left and right edges of both panels, storage space can be expanded both horizontally and vertically. It is possible to reduce the roof surface and increase the volume ratio of the roof surface.Also, the roof element can be
By using a frame with a shaped cross section, unnecessary space is not created, the volume occupied by the space can be minimized, and the frame etc. do not remain in the space when the roof surface is open.

Further, the vertical structure panel is equipped with running wheels, and the top panel is provided with a top guide rail and a guide roller, so that when the roof element is opened/closed, the guide roller of the top panel moves over the top panel of the adjacent roof element. The sliding arrangement on the top guide rail reduces stress on the top panel and reduces the weight of the roof element.

Furthermore, by arranging stiffening surface panels across the left and right ends of the top panel and vertical surface panel of the roof element with a shaped cross section to stiffen the roof element, the element can travel in an arc shape. Even when running on rails, running force can be effectively transmitted to the upper part of the element.

Furthermore, according to the invention, since each of the roof elements runs on a single common running rail, the space requirements for the drive devices including the rails do not overlap laterally and are kept to a minimum.
