BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retractable roof device capable of opening and closing a part of a large roof such as a gymnasium.

[0002]

2. Description of the Related Art Conventionally, a gymnasium such as a school is a large building, and there are various roof devices in which a part of the roof can be opened and closed. For example, fixed roofs 2 and 2 are provided at both ends of the roof 1 of a large building shown in FIG. 1, and a movable roof 4 that can be opened and closed is provided above a large opening space 3 formed in the central portion of the large building. It is covered with No. 4 and is formed into a curved surface of a kamaboko shape. In addition, as shown in FIG. 2, when the roof is viewed from the front, it is formed into a bow shape, and is formed into a curved surface having a larger diameter than the fixed roof 2 located inside, and further, the movable roof 4 located outside. Horizontal beams 5 made of H-shaped steel or the like are provided at both end portions of the horizontal beam, and wheels 6, 6 for traveling are attached to both end portions of the horizontal beam, respectively (FIG. 3).

However, in the conventional movable roof 4 to which a heavy motor is attached, the middle portion of the long cross beam 5 is bent due to its own weight, and there are some which are provided with an intermediate wheel 7 to prevent it. There was a risk of derailing. In order to prevent the bending of the cross beam 5, the weight of the movable roof may be reduced, or the cross beam 5 may be made larger to increase the strength. Then, the weight of the movable roof 4 is further increased, and inevitably. There was a drawback that the noise during driving became loud.

In FIG. 4, wheels 6 are mounted on rails 10 mounted on beam members 9 installed on both sides of an upper part of a large building 8 and horizontal beams 5 located on both end portions of a movable roof 4. As shown in FIG. 5, among the wheels respectively attached to both ends of the wheel, at least one wheel 6 has a gear 6a attached thereto, and a geared motor 12 with a brake mounted on the movable roof 4 is driven. Gear 1
The movable roof 4 is made to travel in tandem with 1.

As shown in FIG. 6, the rail 10 on which the wheels 6 travel is fixed on the beam 9, but the movable roof 4 is levitated from the rail 10 by a typhoon or a sudden strong wind. There is a risk of derailing and being blown away. for that reason,
One or more latching claws 13 for preventing derailment are attached to the lower portion of the cross beam 5 on which the wheel 6 is attached, and the cross beam 5 on which the upper portion or the rail 10 of the beam member 9 and the wheel 6 are attached. Has been suspended. In this case, the beam members 9 and the rails 10 are located on the extension of the curb-shaped curve of the movable roof 4 as shown in FIG. 4, and are mounted in the direction in which the movable roof 4 can move back and forth.

[0006]

As described above, the weight of the movable roof 4 which is large and is formed in a bow shape is perpendicular to the wheels 6 and the rails 10 arranged on the extension of the curve of the bow shape. In order to prevent the wheel 6 from coming off due to a load applied in the direction, a collar portion is provided on one side or both sides of the wheel. However, since an unbalanced load is applied, the contact portion between the wheel 6 and the rail 10 is It was easy to wear unevenly. In order to prevent uneven wear, maintenance and inspection such as lubrication at short intervals is required, or the wheels and rails have to be replaced in a relatively short period of time. Further, the movable roof 4 having the wheels 6 has drawbacks that it is difficult to open and close in a short period of time, and the weight of the movable roof 4 increases because the driving motor 12 is mounted on the movable roof 4.

A motor 12 mounted on a conventional movable roof 4.
Since it is necessary to make an electrical connection between the
The movable roof moves while dragging a heavy cable, a trolley 14 or the like. Therefore, the traveling speed of the movable roof is inevitably limited, and the cable is always dragged, so it is easily damaged and must be replaced regularly at short intervals. There were various problems such as the need to pay attention to an electric leakage accident during rainfall.
The present invention has been made in view of the above problems, and it is an object of the present invention to reduce the weight of a movable roof and to provide a traveling means for preventing an unbalanced load on a rail so that the rail can be easily opened and closed.

[0008]

According to the present invention, an opening is provided between fixed roofs installed at both upper ends of a building, and a movable roof for opening and closing the opening is movably mounted outside the fixed roof. In this roof device, mounting plates are attached to the lower portions of the frame receiving steels provided at both ends of the movable roof, and traveling wheels are attached at regular intervals in pairs on both sides of the mounting plate. A traveling means is provided in which a guide wheel is provided in a notch provided in the mounting plate located between and different from the rotation axis of the traveling wheel by 90 degrees, and a road surface on which the traveling wheel travels is formed on the inner surface of the bottom portion. And a narrow groove portion for moving the mounting plates connected to both ends of the movable roof in the longitudinal direction of the central portion of the ceiling surface located above the road surface, and guide surfaces on which the guide wheels travel are formed on both inner sides. A box rail with a substantially U-shaped cross section At both ends of the upper part of the building, mounting members are obliquely installed at regular intervals along both ends of a movable roof that is movably mounted outside the fixed roof. And the bottom of the box rail with the road surface positioned at an angle such that it is flush with the surface on which the running wheels travel, and the bottom of the box rail is attached to the attachment member, and both ends of the movable roof are attached. By engaging the rack gears installed downwardly downward with the pinion gears that mesh with the brake motor-equipped guard motors installed on the buildings located near the rear of the movable roof, respectively, by operating the motors. The movable roof is moved back and forth to open and close the opening. In addition, the movable roof may be formed in a curved curved shape and installed horizontally or obliquely on the upper part of the building, or may be formed in a flat shape and installed horizontally or obliquely on the upper part of the building. And may be installed horizontally or obliquely on the upper part of the building.

Since the heavy motor is installed on the building without being attached to the movable roof, the weight of the movable roof is reduced and the noise during running is reduced. Further, since the rail is a box rail, the traveling means consisting of traveling wheels and guide wheels traveling inside the rail has a guiding function when traveling on the movable roof and must be derailed. There is no. In addition, the box rail, the traveling wheels and the guide wheels travel while contacting either the road surface or the ceiling surface in the rail and the left or right guide surface, and the traveling surface of the traveling wheels. In addition, since the mounting angle of the mounting member for mounting the bottom of the box rail is adjusted to mount the box rail on the building, an eccentric load is not applied to the contact portion between the traveling wheel and the box rail.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described. In FIG. 7, a roof device 20 of a building 19 such as a gymnasium has an arbitrary cross section. For example, as shown in FIG. 2, it is formed in an arcuate curved surface, and a large opening 22 is formed in the middle portion of the fixed roofs 21, 21 provided at both ends of the roof device. Fixed roof 21 with bow-shaped curved surface
A pair of movable roofs 23, 23 having the same radius and larger radius than that of the fixed roof are mounted on the outer side of the above so as to be openable and closable so that the opening 22 can be covered and opened and closed. The movable roof may be configured as one unit or may be configured as a plurality of units. In the latter case, when the opening 22 is opened, a plurality of movable roofs can be stacked on top of each other to be compactly stored, which is convenient. Is.

In FIG. 8, frame receiving steels 24 are attached to both end portions of the movable roof, and a plurality of running wheels 27 are mounted on a mounting plate 25 provided under the frame receiving steels 24 at regular intervals. I'm wearing it. Since the traveling wheels 27 are not attached to the mounting plate 25 in a cantilever manner and the traveling wheels 27 are attached in pairs on both sides, good balance is achieved. Further, guide wheels 29 each having a rotation axis different from the rotation axis of the traveling wheel 27 by 90 degrees can be rotated in the notches 26 provided between the traveling wheels 27 and provided in the mounting plate 25. The frame receiving steel 24 is prevented from bending by being attached to each of the traveling wheels 27, and being mounted between the traveling wheels 27, 27, respectively. In this case, the difference between the rotational axes of the traveling wheel 27 and the guide wheel 29 is preferably 90 degrees, but it is not necessarily limited to 90 degrees, and the traveling wheel 27 and the guide wheel 29 constitute the traveling means 28.

In FIGS. 9 and 10, reference numeral 30 denotes a box rail for traveling a wheel, which has a substantially U-shaped cross section, and a central portion of a ceiling surface 32, which is located above a road surface 31 on the inner surface of the bottom, extends in the longitudinal direction. A narrow groove portion 33 is formed, and guide surfaces 34, 34 are formed on the inner surfaces on both the left and right sides, respectively. Mounting plate 25 located between the traveling wheels 27, 27 mounted close to each other
In addition, the guide wheel 29, which is horizontally installed in the notch portion 26 provided at a constant or arbitrary arbitrary interval, is provided in the box rail.
It is guided by either of the two guide surfaces 34, 34 of the guide.

The guide wheel 29 has left and right guide surfaces 34, 34.
Since it cannot rotate when it comes into contact with at the same time, the vehicle travels while being in contact with either one of the left and right guide surfaces 34, 34, that is, the guide surface 34a located on the lower side where the weight of the movable roof 23 is added. Both the traveling wheel 27 and the guide wheel 29 are engaged with play in the box rail 30.

In FIGS. 11 and 12, fixed roofs 21 and 21 are attached to both ends of the roof device 20 above the building 19, and movable roofs 23 and 23 located outside the fixed roofs.
Is mounted so that it can run. Therefore, the opening 22
When the roof is opened, the fixed roof 21 and the movable roof 23 can be overlapped with each other to be compact. That is, the bottoms of the box rails 30 are attached to both ends of the roof device by attaching members 35 installed diagonally so as to intersect the arch-shaped curve extension of the movable roof 23. By adjusting the mounting angle of the mounting plate member 35, whether the movable roof is bow-shaped, flat-shaped or mountain-shaped, the box rail 30 and the traveling means 28 can be smoothly moved back and forth without causing an unbalanced load. Can be moved.

A large-sized building 19 having a roof device 20 is equipped with a braked motor 37.
A pinion gear 38 is mounted on the motor shaft of the motor. 39
Is a long rack gear that meshes with the pinion gear 38,
The rack gear 39 is horizontally attached to a lower portion of a connecting plate 40 attached below the frame receiving steels 24 provided on both ends of the movable roof 23. In this case, the tooth groove of the rack gear 39 may be attached upward, but it is preferable to attach the tooth groove of the rack gear downward so that dust and the like are less likely to accumulate in the tooth groove. In this case, the motor is fixed on the building, rotates at a fixed position, and is mounted so as not to move with the movable roof 20. In this embodiment, the rack gear and the pinion gear are used for interlocking with each other, but if the movable roof has a slope or a spherical surface, the wire-drum system can be used.

When the movable roof is formed in one piece, the shape becomes large and the weight increases. Therefore, by forming the movable roof in two pieces, the size per one piece can be reduced to reduce the weight. The shape of the movable roof may be openably and closably provided on a part of the roof 23a formed in a large bow-shaped curved surface as shown in FIG. In addition, as shown in FIG. 2, box rails may be installed on both ends of the movable roof so as to be paired on the same plane. Alternatively, as shown in FIG. 13, both sides of the movable roof 23b may be installed. It is also possible to mount the movable roof 23b at an angle by varying the heights of the box rails 30a to be guided. Even in that case, the traveling wheel 27 and the guide wheel 29
The traveling means 28 composed of is capable of traveling smoothly without an unbalanced load with respect to the box rail 30.

As shown in FIGS. 14 and 15, roofs 23c and 2
Movable roofs 23d and 23f formed in a flat surface on a part of 3e
May be provided horizontally or obliquely. In this case, the movable roof 2
Movable roofs 23d and 23f located on both sides of 3d and 23f
The box rails 30b and 30c for guiding the guides may be attached horizontally or obliquely.

As shown in FIG. 16, a mountain-shaped movable roof 23h may be provided on the top of the roof 23g. In this case, it is also possible to dispose box rails 30d and 30d, which are located on both sides of the movable roof 23h and guide the movable roof, respectively.

The traveling means 28 may be constituted by two traveling wheels 27 and one guide wheel 29 supported at three points, or,
It may be composed of one traveling wheel 27 and one guide wheel 29. Since the traveling wheels 27 and the guide wheels 29 are configured to travel in the box rail 30 with their respective rotational axes different from each other, an unbalanced load is not applied to only one of the wheels and the vehicle smoothly travels. There is no uneven wear.

Next, the operation of the present embodiment will be described. The brake motor 37 installed on the building 19 is fixed at a fixed position, and the motor shaft of the motor is fixed. The pinion gear 38 axially mounted on the gear is engaged with a rack gear 39 which is located below both ends of the movable roof 23 and is attached downward. Therefore, when the motor 37 is driven, the movable roofs 23, 23 having the rack gears 39 are moved forward and backward by the traveling means 28 engaged in the box rail 30 to open the opening 22 as needed. Can be opened and closed quickly.
In this case, since the motor is a brake-equipped guard motor, it stops immediately when the rotation is stopped, and the movable roof does not move too much.

At the ends of the frame receiving steels 24 installed at both ends of the movable roof 23, traveling means 28 consisting of traveling wheels 27 and guide wheels 29 alternately provided with different rotational axes are provided.
Box rails 30 placed on both sides of the upper part of the building 19
It runs while engaging with play inside. Box tray
On the mounting plate 25 that moves in the narrow groove portion 33 provided in the center of the ceiling surface 32 of the rail, the road surface 31 of the box rail is
The guide wheels 29 are mounted in the box rail 30 such that the guide wheels 29 are mounted on the guide rails 29, the guide wheels 29 having the rotation axes centered at, for example, 90 degrees different from each other. Among the left and right side surfaces 34, the traveling wheel 27 smoothly travels while contacting a guide surface 34a located below and traveling while guiding.

On both sides of the upper portion of the building 19, a box rail 30 is provided with road surfaces 31 positioned at angles such that the traveling wheels 27 attached to both ends of the movable roof 23 are flush with the traveling surfaces. The mounting members 35, 35 are mounted at regular intervals along the extension lines of both ends of the movable roof 23 so as to mount.

Since the weight of the movable roof 23 is constantly applied in the vertical direction, the traveling wheel 27 tries to move downward due to its own weight, but the guide wheel 29 is provided 90 degrees away from the rotational axis of the traveling wheel 27. Guide travels while contacting a guide surface 34a located below the box rail. Therefore, the traveling wheels 27 attached to the attachment plate 25 are prevented from moving downward,
Fine groove 3 provided in the middle of the ceiling surface 32 of the box rail
Since the mounting plate 25 does not come into contact with the end of 3, the traveling means 28 travels quietly without producing noise.

Even if a typhoon, a gust of wind or the like is generated and an external force is applied to the movable roof 23 to lift it up, the traveling means 28 including the traveling wheel 27 and the guide wheel 29 inside the box rail 30. Are different from each other in the angle of the rotation axis, and the ceiling surface 32 and the other guide surface 34b in the box rail 30.
A safety device is constructed by having a play and hooking. Therefore, the movable roof 23 is a box rail 30.
You can safely move back and forth without taking off from the car.

A facility for supplying electric power to a movable roof that moves forward and backward through a rack gear that meshes with pinion gears mounted on the motors installed on both sides of the upper part of the building becomes unnecessary, and the weight reduction of the movable roof is promoted for traveling. Prevent the noise inside. Further, the rail is not an ordinary rail but a box rail, and the traveling wheels and the guide wheels in the box rail have different rotational axes from each other by 90 degrees. Since the vehicle travels while being guided by the guide wheels even when an external force is applied to the wheels, the wheels are prevented from falling off and the movable roof is prevented from falling. Further, since the box rail and the traveling means composed of the traveling wheel and the guide wheel are in contact with each other in the vertical direction, an unbalanced load is not applied to the contact portion between the traveling wheel and the rail,
Moreover, since it is not necessary to frequently lubricate each contact surface, maintenance and inspection is easy. In addition, the movable roof can be mounted horizontally because the unbalanced load is not applied to the contact point between the traveling means and the box rail.

[0026]

The present invention eliminates the need for a facility for supplying electric power to a movable roof that moves forward and backward through a rack gear that meshes with a pinion gear mounted on a geared motor with a brake installed on both sides of the upper part of a building. Since the cable does not move while being dragged, the weight reduction of the movable roof can be promoted, the noise during traveling can be prevented, and the rotation of the motor can be immediately stopped. In addition, the traveling means including the traveling wheels and the guide wheels, which are provided with the rotational axes different from each other by 90 degrees, provide play on the road surface and the ceiling surface in the box rail and the guide surfaces to make them contact in the vertical direction. Therefore, even if the movable roof has a bow shape, a flat plate shape, or a mountain shape, the bottom of the box rail is attached to a mounting member that is installed diagonally above the building, so that the running wheels and rails are vertical. Since they contact each other in the direction, the movable roof can be run without applying an unbalanced load to the contact portion.
