Then, radial arch beams 5 are arranged on the upper surface of the roof 1 at six equal positions on the roof 1,
The first and second movable elements 3, 2 are supported by one of the two support pins 7 on the support 6 suspended from the center of the arch beam 5.
The top of 4 is rotatably supported. And these first,
The second elements 3 and 4 are moved from the fully closed position shown in FIG. 9 to the fixed element 2 by moving the lower ends of the second elements 3 and 4 in the circumferential direction around the support pin 7 via the carriage 8.
The first movable element 3 and the second movable element 4 can be sequentially overlapped with each other on the inside, and the movable roof elements 3 and 4 can be fully opened.

In the above structure, the carriage 8 at the lower ends of the first and second movable elements 3 and 4 has a vertical load W ₁ and a horizontal outward direction due to the weight of the movable elements 3 and 4, as shown in FIG. Since the load W ₂ is added to the
Is formed into a stepped shape, and the vertical load W ₁ is applied to the main wheel 8a.
It is configured to be received by the horizontal surface 9a via the vehicle and the horizontal load W ₂ on the vertical plane via the side wheels 8b.

According to the invention the problem above conventional configuration you try solving, for receiving a load W ₂ in the horizontal direction, the basis of the side wheels 8b and high strength 9 is required, the movable panel 3 further along the large foundation 9 of irregularities Since a large load is applied to the side wheels 8b when the 4 and 4 are turned, or when the arch beam 5 is bent due to load fluctuations and temperature changes, a complicated mechanism that does not damage the side wheels 8b is required. .

In addition, a structure that can withstand heavy loads due to snow was required in snow areas.

It is an object of the present invention to provide an openable dome type roof that can solve the above problems by eliminating side wheels.

Means for Solving the Problems In order to solve the above problems, a first aspect of the present invention includes a plurality of fan-shaped movable roof elements which are rotatable around a support pin at a central top of a roof, and the movable roof elements are rotated. In a dome-shaped roof that can be moved to open and close the roof, a supporting carriage that supports the lower end of the movable roof element at a plurality of lower ends of the movable roof element is moved along a fixed path along the turning direction of the movable roof element. Arranged freely, a slide member is attached to the lower end of the movable roof element corresponding to the support carriage, and the slide member is attached to the support carriage in a normal direction orthogonal to the turning movement direction of the movable roof element. A slide base that guides slidably is provided, and this slide base absorbs the displacement of the lower end portion due to the bending of the movable roof element. It is composed.

A second aspect of the present invention is a dome-shaped roof that includes a plurality of fan-shaped movable roof elements that can pivot about a support pin at the central top of the roof and that pivots the movable roof elements to open and close the roof. A supporting carriage supporting the lower end of the movable roof element at the lower end portions of the movable roof element is movably arranged on a fixed path along the turning movement direction of the movable roof element, and at the lower end of the movable roof element, A slide member is attached corresponding to the support carriage, and the support carriage is provided with a slide base for slidably supporting the slide member in the normal direction orthogonal to the turning movement direction of the movable roof element. The movable roof element is configured to absorb the displacement of the lower end portion due to the bending, and the movable roof element is fully closed at the fully closed position. It is provided with a support device urges ride member inwardly.

Effect According to the configuration of the first aspect of the invention, when the movable roof element is bent due to snowfall or temperature change and the support position of the lower end portion changes, the support carriage moves in the turning direction and the slid member moves on the slide base. The lower end is not constrained by moving in the direction normal to the turning direction, and stress due to strain is not applied to the support. Further, since the lower end of the movable roof element is slidably supported in the normal direction, no horizontal load is generated, and therefore the supporting carriage only needs to support the vertical load, and the structure can be extremely simple.

According to the configuration of the second invention, in addition to the effect of the first invention, the outward sliding of the lower end of the movable roof element from the support device is restricted at the fully closed position, and the lower end of the movable roof element is further restricted. By urging the portion inward to give pre-compression, it is possible to counter an increase in load due to snow and the like, and increase the strength and rigidity of the movable roof element.

Embodiment One embodiment of the present invention will be described below with reference to FIGS. 1 to 8. The same members as those in the conventional example are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIGS. 4 and 5, at the lower ends of the first and second movable elements 3 and 4, a self-propelled vehicle which can travel freely on a pair of left and right traveling rails 22 laid on a horizontal plane foundation 21. For example, four supporting trolleys 23 are arranged at predetermined intervals. That is, as shown in FIGS. 1 to 3, the lower end portions of the first and second movable segments 3 and 4 are swingably connected to the predetermined positions of the lower ends of the first and second movable segments 3 and 4 through horizontal pins 24 parallel to the traveling rail 22. The upper and lower brackets 25A and 25B are attached, and the slide member 26 is disposed on the bottom of the lower bracket 25B. On the other hand, on a carriage main body 29 in which front wheels 27 and rear wheels 28 are disposed on both left and right sides, a swingable slide base 31 is supported via a horizontal support shaft 30 orthogonal to the traveling rail 22. A slide groove 31a is formed on the surface of the slide base 31 for supporting the slide target member 26 so as to be swingable in the horizontal direction orthogonal to the traveling rail 22. The member to be slid 26 is fitted to the inner surface of the slide groove 31a via the slide plates 26a or bearings attached to the bottom and both sides, and is configured to reduce sliding resistance. Further, a traveling drive device (not shown) having a reduction gear is arranged in the bogie main body 29, and a drive gear 33 attached to an output shaft 32 of the travel drive device 34 is attached to a front wheel 27 and a rear wheel 28. It is meshed with 35 and driven to run.

This openable dome type roof is provided with a support device 41 that can more firmly fix the movable panels 3 and 4 during snow or strong wind. That is, as shown in FIG. 6, a lock base 42 is erected on the foundation 21 outside each support carriage 23 in the fully closed position, and a slide member is slid inward on the lock base 42. A locking jack 43 that supports the upper bracket 25A so that the upper bracket 25A can be biased in the direction. As shown in FIG. 7, a pressing plate 44 having a horizontal engaging groove 44a is attached to the tip end of the operating rod 43a of the locking jack 43, and the engaging groove is formed on the outer surface of the upper bracket 25A. A receiving plate 45 having an engaging projection 45a into which 44a can be fitted is attached. Therefore, the operating rod 43a of the locking jack 43
By pushing the pressing plate 44 against the pressure receiving plate 45, and by engaging the engaging groove 44a of the pressing plate 44 with the engaging projection 45a, the movable elements 3 and 4 are pressed according to the swing of the lower ends. The force can be reliably transmitted to the upper bracket 25A. The back plate 4
5 may be attached to the lower end of each movable panel 3, 4.

Here, the fulcrum reaction force when the arch-shaped beam is supported by a pin or slid in a horizontal direction will be described with reference to FIGS.

As shown in FIG. 8 (a), when the arched beam A is supported by the lower fulcrum a and the upper fulcrum b by pins and hinges, the fulcrum reaction force is almost the same as that of the conventional movable elements 3 and 4. Equivalent to power. That is, the vertical reaction forces Ra and Rb of the lower fulcrum a and the upper fulcrum b are Ra> Rb, and the horizontal reaction force H
a and Hb are Ha = Hb. The bending moment applied to the beam A at this time is MA. Further, as shown in FIG. 8B, when the arched beam B is supported at the lower fulcrum c so as to be slidable in the horizontal direction and is supported by the pin and the hinge at the upper fulcrum d, it is almost the same as this embodiment. Will be the same. That is, the vertical reaction forces Rc and Rd of the lower fulcrum c and the upper fulcrum d are Rc = Rd
In addition, Ra <Rc, Rb> Rd, and the fulcrum reaction force in the horizontal direction does not occur. However, the bending moment MB applied to the beam B at this time is large, and MA <MB. Therefore, the one shown in FIG. 8 (a) requires a large supporting force at the lower fulcrum a, and the one shown in FIG. 8 (b) requires a beam B having high rigidity capable of resisting the bending moment MB.

According to the above configuration, the arch beams 5 are bent due to load fluctuations and temperature changes, and the positions of the support pins 7 are displaced. Accordingly, even if the lower ends of the movable elements 3 and 4 move, the support carriage 23 moves. Since it can be absorbed by the movement along the traveling rail 22 and the slide along the slide groove 31a of the slide target member 26, a horizontal load is not applied to the support carriage 23 portion. Further, even when the movable elements 3 and 4 are bent due to load fluctuations or temperature changes, they can be absorbed by the movement of the support carriage 23 and the sliding member 26 sliding in the same manner. Therefore, it is not necessary to use a stepped foundation or side wheels for supporting a load in the horizontal direction as in the conventional case, and further, the bending of the movable elements 3 and 4 adds a horizontal force to the support 6 at the top of the arch beam 5. There is no directional load, and therefore no strength is required.

Also, before the snowfall season or before the arrival of a typhoon, the jacks for locking 43
And pushes the pressing plate 44 into contact with the receiving plate 42 of the upper bracket 25A to restrain the lower ends of the movable elements 3 and 4 from sliding outward, and further lock the jack 43.
A predetermined amount to slide the slide target member 26 inward along the slide groove 31a, and by pre-compressing the movable elements 3 and 4, the repulsive force is used to apply a load such as snow. The rigidity against it can be further improved. In this way, since the rigidity of the movable elements 3 and 4 with respect to the load can be increased by the support device 41, it is also necessary to increase the strength and rigidity of the movable elements 3 and 4 themselves so that they can handle the maximum load such as snow. Without
It is possible to reduce the weight of each movable element 3, 4.

EFFECTS OF THE INVENTION As described above, according to the first invention, the lower part of the movable roof element is slidably supported on the supporting carriage in the direction normal to the turning movement direction of the supporting carriage. Even if bending occurs due to load fluctuation or temperature change, it can be easily absorbed, and it is not necessary to support the horizontal load by the supporting carriage portion, so that the foundation and the supporting carriage can have a simple structure.

According to the second invention, in addition to the effect of the first invention,
By supporting the lower end of the movable roof element with a support device during a snowfall season to receive a horizontal reaction force, and by pre-pressurizing the movable roof element in advance to give it a pre-compression, it is possible to cover snow and strong winds. The maximum load can be counteracted, and the strength and rigidity of the movable roof element itself can be reduced by the amount of strength and increase, and the weight can be reduced.
