Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a foldable open / close roof apparatus, and particularly to a foldable open / close roof apparatus suitable for a large-scale building.
[0002]
[Prior art]
In recent years, large-scale buildings with all or part of the roof being openable / closable have become widespread as athletic facilities or multipurpose facilities. For example, movable roofs that do not deform are placed on fixed roof openings and fixed roofs. Alternatively, some roofs can be opened and closed by moving between the lower storage positions.
[0003]
However, in this example, since it is necessary to provide a storage position above or below the fixed roof, there is a problem that the opening ratio of the roof is limited and a large space is required for storing the movable roof.
In view of this, a folding openable roof that can reduce the length of the movable roof when the movable roof is stored to reduce the storage space has been proposed as described in Japanese Patent Application Laid-Open No. 10-102666.
[0004]
This foldable open / close roof has a large number of open / close units arranged in the front-rear direction, which is the extending direction of the travel path, between the travel paths arranged parallel to each other along the left and right edges of the opening of the roof. Become. The open / close unit is formed by pivotally connecting the upper ends of a pair of panel-like open / close frames made of a flat truss that is long in the left-right direction, so that both open / close frames can be opened and closed on the lower side. And the lower part of both opening-and-closing frames is connected with the connecting material which can be extended so that the opening and closing is possible, and the opening-and-closing frame which makes an isosceles side in the cross section and the connecting material which makes the bottom form a triangle. . The front and rear opening / closing units whose cross section is substantially triangular form a foldable opening / closing roof that is continuous at the lower end of the opening / closing frame and continues in a bellows-like manner as a whole.
[0005]
[Problems to be solved by the invention]
In the open / close roof described in the above-mentioned publication, both open / close frames that are pivotally attached to each other are formed in a panel shape that is formed of a flat truss that is long to the left and right between the left and right traveling paths. In other words, it has a rigid structure. For this reason, since the length of the open / close frame becomes large when it becomes a large open / close roof with a wide opening, the open / close frame bends especially during the open / close movement, and the hinge pin pivotally attaches both open / close frames. Excessive shearing force is applied to the. For this reason, if the rigidity of the plane truss of the opening / closing frame is increased in order to prevent the bending, there is a disadvantage that the amount of the steel frame is increased and structurally and economically disadvantageous.
[0006]
In addition, since the bellows type open / close roof has a panel-like open / close frame with high rigidity as described above, the control of the left and right drive devices for moving these along the travel path is as follows: As a result of being required to be precise so as not to cause distortion in each open / close frame, there is also a problem that the control of the driving device becomes complicated.
Accordingly, an object of the present invention is to obtain a folding roof in which excessive force is not applied to the hinge pin for opening and closing even if the member is bent during traveling for opening and closing. An object of the present invention is to obtain a lightweight folding roof with a small amount of steel frame even in a large-scale open / close roof with a large span of left and right traveling paths, and an object of the present invention is to reduce the scale of the left and right drive devices. The object is to obtain a foldable roof that is sufficient and can easily drive the left and right drive devices.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the invention of the folding openable roof apparatus according to claim 1 is characterized in that left and right parallel traveling paths respectively provided along opposing parallel edges of a roof opening and both traveling A large number of beams built between the roads and configured to be movable back and forth, Next to each other Between the beams , Multiple locations in the longitudinal direction of the girder In addition, Built independently of each other, Next to each other Refracted when the space between the beams is closed In a state While structurally independent between the two beams, Next to each other Extends when the space between the large beams opens Next to each other By structurally integrating the beams Next to each other Form a structural frame with the girder plural With a small beam, Next to each other And a foldable or deflectable roof material disposed between the large beams.
[0008]
Here, the structural independence between the large beams means that the transmission of force between the large beams is cut off and the large beams are not restrained from each other, and only support the load that is applied to them, such as their own weight and load capacity. The state to do. Also, structural integration between the large beams means that the adjacent large beams are constrained via small beams, and the adjacent large beams work together to support their own weight, loading load, wind pressure, etc. Say. The structural frame refers to a frame that is formed by adjacent large beams among elements constituting the roof and a small beam between the large beams, and supports its own weight, loading load, wind pressure, and the like.
[0009]
According to the first aspect of the present invention, by moving the girder back and forth, the interval between the girder beams connected in the front and rear direction is gradually increased, and the roof is closed while the girder is extended, or the interval is gradually reduced to reduce the girder. The roof is folded and opened while being bent.
In this case, when the roof is closed, the girder moves sequentially from the front end in the moving direction, and the girder is extended by increasing the distance from the girder in the next row. On the contrary, when the roof is opened, the trailing beam is refracted by the approaching approaching beam on the front side in the moving direction. In addition, the order of movement of each large beam in the front-rear direction is not limited to the above, and it may be one that sequentially moves from the rear end in the moving direction and finally closes the roof, or sequentially moves from the front end in the moving direction. Then, the roof may be opened.
[0010]
Here, when traveling drive devices are provided on the left and right sides of each large beam to make each large beam self-propelled, each traveling device is sequentially controlled so that the front and rear large beams perform the above-described operation. Thus, when the traveling drive device is individually provided for each large beam, the individual travel drive devices are small and sufficient, and those loads are distributed and loaded on the travel path. Therefore, a member such as a keel truss that supports the travel path. The burden of is small.
[0011]
In addition, when the travel drive device is connected to the large beam that forms one of the front and rear ends and the travel drive device is not connected to the other large beams, the movement of each large beam is caused by the movement of the driven large beam through the small beam. Then, the next large beam is moved, and the moving force is sequentially transmitted toward the large beam at the other end. In this case, since the number of travel drive devices is small, the control becomes easy.
[0012]
One opening of the roof can be installed with a pair of foldable open / close roofs, so that the entire opening can be opened and closed, and each foldable open / close roof can be installed in the longitudinal direction of the runway. By providing a pair in the front-rear direction, a double-opening open / close roof can be provided.
Here, when the folding roof is open, the small beams are refracted to structurally make the front and rear large beams independent. For this reason, the transmission of force between the large beams is interrupted and the large beams are not restrained from each other, and only the load applied to itself such as its own weight and the load load is individually transmitted to the traveling path. For this reason, the length of the large beam is increased due to a large open / close roof having a large width of the opening, and even if the large beam is bent during the opening / closing movement, the other large beams are not affected by the bending. In addition, since the small beams are erected independently from each other at a plurality of locations in the longitudinal direction of the large beams, the amount of bending and distortion of the large beams at the hinges in each small beam is negligibly small. The shear force applied to the hinge pin is small. For this reason, since the large beams are allowed to bend and distort, even with an open / close roof with a large span between the left and right travel paths, it is possible to reduce the weight of the steel frame and reduce the weight. The non-synchronization of the traveling body is allowed, and the control of the driving device for the beam is facilitated.
[0013]
Further, when the folding roof is closed, the small beams are extended to structurally integrate the front and rear large beams, and a structural frame is formed by the adjacent large beams and a plurality of small beams therebetween. For this reason, since the adjacent large beams are constrained via the small beams to form a structural frame, the structural frame supports its own weight, loading load, wind pressure, and the like and transmits them to both travel paths. For this reason, in the closed state, the strength of the folding roof increases.
[0014]
Here, in order to extend the small beam and structurally integrate the front and rear large beams, the distance between the large beams may be increased by the travel drive device. However, in the final process of extending the small beams, To extend completely, a heavy load may be imposed on the travel drive device. Therefore, in this final process, a telescopic drive member such as a hydraulic or pneumatic cylinder device is stretched across the refraction part of the small beam, and finally the small beam is supported with the assistance of its power. When it is extended, the burden on the travel drive device is reduced, so that it is not necessary to increase the scale. In addition, since the extension state of the small beam can be maintained by such a telescopic drive member, even if there is an input in a direction in which the distance between the front and rear large beams is narrowed with respect to the large beam, the small beam maintains the extended state and the front and rear The structural integration between the beams can be strengthened.
[0015]
Further, when the small beam is extended only by the movement of the large beam by the traveling drive device without using the expansion / contraction driving member, a lock mechanism for maintaining the extended state of the small beam is provided instead of the expansion / contraction driving member. That's fine. When the locking mechanism is in an activated state, the structural frame is formed by structurally integrating the front and rear large beams. On the contrary, if the operation of the lock mechanism is released, the small beam can be refracted and the front and rear large beams can be structurally independent.
[0016]
The invention of the folding open / close roof apparatus according to claim 2 makes the posture of the large beam variable according to the gradient of the traveling path by supporting the large beam on the traveling path at at least two front and rear positions. That is, for example, the large beam is supported on the traveling road by two front and rear wheels at both left and right ends.
According to the invention of claim 2, since the girder is supported at two front and rear positions, the posture is changed according to the inclination of the traveling road. For this reason, in a foldable roof with a sloping roof, the angle between the large beam and the small beam installed between the large beams in the vertical plane, that is, the large beam when viewing the direction from one traveling path to the other traveling path The angle between the beam and the small beam is substantially the same at each position in the traveling direction. For this reason, the intensity | strength of the said structure frame in each position when a folding roof is closed can be set comparable. In addition, the relative accommodation of large beams, small beams, roofing materials, and rain related to them is almost the same in the front-rear direction, making it possible to make an open / close roof economically with little variation in performance. .
[0017]
The invention of the foldable open / close roof apparatus according to claim 3, In side view, It is formed in a triangular cross section with a wide front and back width and a narrow bottom surface and the lower beam is refracted downward at the front and rear intermediate parts. Make the structure possible Both In side view, The thickness of the part close to this refracted part Relatively Large and pivotal parts to the front and rear beams As we head for Reduce thickness Shape The front and rear width of the upper surface is narrow and the front and rear width of the lower surface is wide at the time of refraction downward.
[0018]
According to the invention of claim 3, when the opening and closing roof is opened and the interval between the large beams is narrowed, a space is formed between the front and rear large beams, the upper portion being narrow and the lower portion being wide. Since the front and back width of the upper surface is narrow and the front and back width of the lower surface is wide, the small beams can be accommodated in the space between the large beams, so the folding length of the opening and closing roof when the opening and closing roof is opened Can be reduced.
[0019]
The invention of the folding open / close roof apparatus according to claim 4 uses a membrane material as the roof material, and a tension is applied to the membrane material by applying tension to the membrane material when the space between the front and rear of the beam is opened. An imparting mechanism is provided.
As a result, tension is given to the membrane material, so that the shape as a roof material is stabilized, flapping by wind is prevented, and the flow of rainwater is also smooth.
[0020]
The invention of the folding type openable / closable roof apparatus according to claim 5 uses a double membrane material as the roof material, and supplies air pressure between the double membrane materials when the space between the front and back of the girder is opened. A tensioning mechanism is also provided to apply tension to these membrane materials. This also provides tension to the membrane materials, which stabilizes the shape of the roof material and prevents fluttering by the wind, and the flow of rainwater is also smooth. become.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows an embodiment of the present invention, and FIG. 1 is a perspective explanatory view of a foldable open / close roof apparatus. Here, for the convenience of explanation, a state in which the open / close roof 15 is closed in the right half is shown, and the open / close roof is shown in the left half. 15 shows a state in which 15 is opened from the opened state to the right.
[0022]
In FIG. 2, one open / close roof 15 is installed on the left and right traveling rails 11. For convenience of explanation, the left half of the figure is opened by moving the entire open / close roof 15 to the left. The entire roof in the state is shown, and the right half of the figure shows about half of the roof in the state in which the open / close roof 15 is closed. Although the present invention includes both open / close roofs 15 of single-opening and double-opening, the following description will be based on a single-opening embodiment in which one open / close roof 15 is installed on the traveling rail 11.
[0023]
In this embodiment, the main body of the building is omitted, and the fixed roof 16 is only shown in FIG. 3, but the building is a large building such as a sports facility, a concert hall, or a multipurpose hall. It can be applied to various types if there is.
A flat rectangular opening 26 is opened at the center of the fixed roof 16, and the keel truss 10 is installed under the fixed roof 16 along the edge of the long side of the opening 26. Both ends of the keel truss 10 are supported by load-bearing portions such as pillars in the building, and the load-bearing portions support the loads of the folding openable roof 15 and the fixed roof 16 via the keel truss 10.
[0024]
On the upper side of the keel truss 10, a traveling rail 11 serving as a traveling path is provided on the edge of the fixed roof 16. The traveling rail 11 is parallel in plan view along the edges of the left and right long sides of the opening 26, and the fixed roof 16 has a shape in which the central portion is high and the peripheral portion is low. Following that, it has the same arch shape in side view.
[0025]
A traveling body 17 composed of wheels or the like is engaged with each traveling rail 11 so as to travel along the traveling rail 11. A large beam 12 to be described later is installed between the left and right traveling rails 11 via the traveling body 17, and two traveling bodies 17 are attached to each large beam 12 at the left and right ends of the large beam 12. . Although not shown, at both left and right ends of each large beam 12, a driving device for driving the large beam 12 is provided on at least one of the front and rear traveling bodies 17. Accordingly, each large beam 12 is provided with a traveling drive device on the left and right. As the driving device, various devices can be adopted as long as the device can apply a force for reciprocating the large beam 12. For example, an electric or hydraulic motor that uses the traveling body 17 as a wheel and is connected to the wheel axle directly or through a gear is one of them. As the traveling body 17, any one that can move along the traveling rail 11 while being engaged with the traveling rail 11 such as a mechanism that slides along the traveling rail 11 can be applied.
[0026]
As the large beam 12 constructed between the left and right traveling rails 11 via the traveling bodies 17 and traveling on the traveling rails 11, a truss composed of an upper chord material 12a, a lower chord material 12b, a lattice bar 12c, and a web material 12d. A beam is used. The upper chord member 12a of the girder 12 has a wide front-rear width, and the lower chord member 12b has a narrow front-rear width, and the cross section has a wide upper portion. Further, the upper chord material 12a has the same height from side to side, but the lower chord material 12b is higher at the left and right and lower at the center, so that the large beam 12 has a larger vertical dimension at the center than at the left and right.
[0027]
At the left and right ends of the large beam 12, the traveling body 17 is attached to the lower surface of the upper chord member 12a via a bracket 18, so that the large beam 12 is installed between the left and right traveling rails 11 so as to be movable back and forth. A number of large beams 12 are disposed in the same manner in the front-rear direction. Further, since a plurality of the traveling bodies 17 are attached at the left and right ends of each large beam 12, the large beams 12 are inclined forward and backward in accordance with the inclination of the traveling rail 11 in the front-rear direction. Accordingly, the longitudinal inclination angle of each large beam 12 changes according to the position of each large beam 12 on the traveling rail 11 having an arch shape in side view as a whole. In FIG. 6, the left end portion of the large beam 12 is shown, but the right end portion appears symmetrically.
[0028]
A small beam 13 is provided between the front and rear large beams 12 arranged on the traveling rail 11, and a roof material 14 made of a film material is stretched between the large beams 12 above each small beam 13. ing. The small beams 13 are provided between the large beams 12 independently of each other at a plurality of positions in the longitudinal direction of the beams 12.
As shown in FIGS. 5 and 6, the beam 13 includes a front portion 13a, a rear portion 13b, and a middle portion 13c therebetween. The front portion 13a is composed of an upper chord member 19a, a lower chord member 19b, and a vertical member 19c. The upper chord member 19a has a plurality of steel members arranged in the width direction and extending in the front-rear direction at a plurality of positions in the width direction. The lower chord material 19b is slightly shorter than the upper chord material 19a but has the same structure as the upper chord material 19a, and the front end of the lower chord material 19b is fixed near the front end of the upper chord material 19a. At the same time, the rear ends of the upper chord member 19a and the lower chord member 19b are rigidly connected via a vertical member 19c, so that the front portion 13a of the beam 13 has a triangular shape with a large vertical thickness at the rear end portion in a side view. . The rear portion 13b is formed symmetrically with the front portion 13a and has the same structure. Further, the middle portion 13c is formed in a rectangular parallelepiped having the same thickness as the rear end portion of the front portion 13a by rigidly coupling a steel material shorter than the front portion 13a and the rear portion 13b.
[0029]
The rear end of the front portion 13a and the front end of the middle portion 13c have the same height and are pivotally attached to the upper end via the hinge 21, and the front end of the rear portion 13b and the rear end of the middle portion 13c are also the same height. The front portion 13a, the middle portion 13c, and the rear portion 13b constitute a small beam 13 that is pivotally attached to the upper end via a hinge 21. The small beam 13 is pivotally attached to the front and rear large beams 12 via the hinges 22 at the front and rear ends. Therefore, when the distance between the front and rear large beams 12 is narrowed, it is refracted downward and the middle portion 13c is lowered. It is like that. FIG. 5 shows a state in which the right beam 13 extends and the beam 13 on the left side is refracted.
[0030]
Since the small beam 13 has the above-described structure, the lower beam 13 is configured such that the front-rear width on the upper surface is narrow and the front-rear width on the lower surface is wide at the time of downward refraction, like the left beam 13 in FIG. Therefore, it adapts to the space between the two large beams 12 when the front and rear large beams 12 having a wide upper and lower width on the upper surface and a narrow lower width on the lower surface approach each other. For this reason, since the folding length of the open / close roof 15 is shortened when the open / close roof 15 is opened, and the space occupied by the open / close roof 15 is narrowed, the opening 26 can be largely opened.
[0031]
Further, since the small beam 13 has the middle portion 13c between the front portion 13a and the rear portion 13b, a space is formed between the front portion 13a and the rear portion 13b in the refraction state. It becomes a space for storing a roof material 14 described later made of a membrane material. For this reason, since the roof material 14 is sandwiched between the front portion 13a and the rear portion 13b and is not compressed, the roof material 14 can be prevented from being deteriorated.
[0032]
The hinge 22 that pivotally attaches the small beam 13 and the front and rear large beams 12 and the hinge 21 that pivotally attaches the middle portion 13c of the small beam 13 and the front and rear portions 13a and 13b have sufficient strength. Of the plurality of small beams 13 between the front and rear large beams 12, in the small beams 13 near the left and right ends of the large beam 12, between the front portion 13a and the middle portion 13c, and between the rear portion 13b and the middle portion 13c. Between them, a hydraulic jack 20 comprising a cylinder device is provided between them. However, a pneumatic jack can be used instead of the hydraulic jack 20. One hydraulic jack 20 has a cylinder tube pivotally attached to the front portion 13a, and the piston rod tip is pivotally attached to the middle portion 13c, and the other hydraulic jack 20 pivotally attaches the cylinder tube to the rear portion 13b. The piston rod tip is pivotally attached to the central portion 13c.
[0033]
The reason why the hydraulic jack 20 is provided on the small beam 13 near the left and right ends of the large beam 12 is to avoid interference between the hydraulic jack 20 and the large beam 12 when the open / close roof 15 is opened. In the portion of the small beam 13, the lower chord member 12 b of the large beam 12 is located higher than the hydraulic jack 20, so that there is no possibility of the interference when the open / close roof 15 is opened. If there is no possibility of such interference, the hydraulic jacks 20 can be provided on all the small beams 13 in the left-right direction. Further, when there is a possibility that the hydraulic jacks 20 interfere with each other between the small beams 13 before and after the large beam 12, the mounting position of the hydraulic jack 20 on the small beams 13 may be biased left and right. FIG. 6 shows a state in which the hydraulic jacks 20 on the front portion 13a side and the rear portion 13b side of the small beam 13 are offset to the left and right. The arrangement is similar.
[0034]
The hydraulic jack 20 has two usage patterns. The first is to assist the extension of the small beam 13 by the movement of the large beam 12 in the final process when the small beam 13 is extended. Therefore, the small beam 13 is finally extended by using the contraction force of the hydraulic jack 20 as an auxiliary force. To maintain this state. Further, when the small beam 13 is refracted, the hydraulic jack 20 is extended while the front and rear large beams 12 are brought close to each other to assist refraction. As a result, the small beam 13 starts refraction, but thereafter, the refraction proceeds only by the movement of the large beam 12. Thus, the hydraulic jack 20 assists the bending of the small beam 13 and maintains the extended state of the small beam 13 in the final process when the small beam 13 is extended and the initial process when the beam is refracted. In this case, the hydraulic jack 20 is free in other processes in bending and stretching of the small beam 13 and is configured to expand and contract with the bending and stretching of the small beam 13. Therefore, the hydraulic jack 20 in this case has a function as a lock mechanism that locks the extended state of the small beam 13 in addition to the function of the telescopic drive member.
[0035]
A second usage pattern of the hydraulic jack 20 is a usage pattern as a locking mechanism that performs expansion / contraction of the small beam 13 only by movement of the large beam 12 and locks the state when the small beam 13 is extended. In this case, it is only necessary to switch between the locking operation and unlocking. Therefore, in this mode of use, it is not always necessary to use a cylinder device such as a hydraulic jack, as long as it is a member or device that can be switched between lock and unlock.
[0036]
When the extended state of the small beam 13 is locked and the two large beams 12 are structurally integrated, the entire small beam 13 functions as a single beam, and thus forms a structural frame together with the two large beams 12. When the small beam 13 is refracted, the two large beams 12 are structurally independent.
Between the rear edge of the front large beam 12 and the front edge of the rear large beam 12, a roof material 14 made of a film material passing over the upper side of the small beam 13 is suspended. Reference numeral 24 a is a fixing portion of the roof material 14 in the large beam 12. In addition, a fixing portion 24b for fixing the intermediate portion in the front-rear direction of the roofing material 14 is also provided at the upper end of the vertical bar erected on the upper surface of the middle portion 13c of the beam 13. These fixing portions 24a and 24b are each made of a bar material extending in the left-right direction.
[0037]
By appropriately setting the length of the vertical bar that supports the fixing portion 24b on the middle portion 13c of the small beam 13, in the extended state of the small beam 13, a tension is applied to the roof material 14 so that the roof material 14 has a predetermined length. Therefore, the fixing portion 24b and the vertical bar constitute a tension applying mechanism for the roofing material 14.
Further, the upper chord material 12a of each girder 12 is provided with a flat plate over the entire upper surface of the girder 12, and this also forms a part of the roofing material, and the whole roofing material includes the membrane material 14 and the upper surface of the girder 12 in the longitudinal direction. Are continuously formed alternately, and in the fixing portion 24a, the rain between the film material 14 and the upper surface of the large beam 12 is sufficiently performed. It goes without saying that each rain between the left and right ends of the membrane material 14 and the fixed roof 16 is sufficiently performed by means not shown.
[0038]
In this embodiment, a film material is used as the roofing material 14, but the roofing material 14 may be formed of a plate material that can be refracted in the fixing portion 24 b. In this case, the height of the fixing unit 24b is set so that the distance between the front fixing units 24a and 24b and the distance between the rear fixing units 24a and 24b are always the same when the beam is extended and refracted. You just have to. In addition, at the end on the closed side that forms the open / close roof 15, the roof material 14 is stretched between the last beam 12 and the fixed roof 16 or the building body.
[0039]
A lid 23 projects from the front and rear edges of the upper chord member 12a in the large beam 12 toward the edge of the upper chord member 12a in the adjacent large beam 12. This lid 23 is continuous over the length direction of the girder 12, and when the open / close roof 15 is opened and the front and rear girder 12 approach each other, it is spanned between the two girders 12 and the rain finish between them. It is designed to be covered. The opening and closing of the lid 23 may be operated by a driving device such as a cylinder device, or may be operated using the moving force of the adjacent large beam 12.
[0040]
Thus, when the large beam 12 of the open / close roof 15 is moved either forward or backward by driving the traveling drive device provided on the traveling body 17 of the large beam 12, the distance between the large and small large beams 12 is sequentially expanded. 13, the roof 15 is closed while extending, or the interval is sequentially reduced, and the roof 15 is folded and opened while the beam 13 is refracted.
In this case, when the open / close roof 15 is closed, as shown in the left half of FIG. 1, the small beams 13 are extended by the large beams 12 sequentially traveling in the direction of the thick arrows (the right beams 13 in FIG. 5). Status). On the contrary, when the open / close roof 15 is opened, the power of the traveling drive device of each large beam 12 travels in the opposite direction when each large beam 12 is closed, and the adjacent large beams 12 approach each other, whereby the small beam 13 is refracted. (The state of the left beam 13 in FIG. 5), the open / close roof 15 is sequentially folded to the storage position. Thus, the opening and closing of the open / close roof 15 is performed by sequentially moving the large beams 12 from the large beam 12 at one end toward the large beam 12 at the other end.
[0041]
At this time, when the slope of the traveling rail 11 is a sloping road that varies depending on the position as in this embodiment, the girder 12 changes its posture in response to a change in the slope of the traveling rail 11. That is, the center line facing the vertical direction of the large beam 12 is perpendicular to the portion of the traveling rail 11 where the traveling body 17 of the large beam 12 is engaged. The traveling rail 11 having a side arch shape as a whole is also in a state close to a straight line between the two large beams 12 in the longitudinal direction, that is, the posture of the two large beams 12 is between the front and rear large beams 12. Almost the same.
[0042]
For this reason, in the state in which the open / close roof 15 is closed and the small beam 13 is extended, the angle in the vertical plane between the front and rear large beams 12 and the small beams 13 therebetween is approximately at each position in the front and rear direction of the traveling rail 11. It becomes the same angle. Therefore, the strength of the structural frame constituted by the front and rear large beams 12 and the small beams 13 between them at each position when the open / close roof 15 is closed is the same in the front-rear direction of the open / close roof 15. In addition, since the relative accommodation of the large beam 12, the small beam 13, the roofing material 14, the rain, etc. is substantially the same, there is little variation in the performance of each part, and it is also economical.
[0043]
Further, a plurality of the small beams 13 are arranged between the front and rear large beams 12, and these are arranged between the large beams 12 at a predetermined interval and independently from each other on the left and right. The amount of bending and distortion of the large beam 12 in the portion is so small as to be negligible, and therefore the shearing force applied to the pin of each hinge 22 is small.
Since the large beam 12 is allowed to be bent and distorted in this way, even the open / close roof 15 having a large span between the left and right traveling rails 11 can be reduced in weight by suppressing the amount of steel frames. In addition, since the left and right traveling bodies 17 are not required to be tuned with high precision, the control of the driving devices of the respective beams 12 is facilitated. Further, since an unreasonable force is not applied to the pin of the hinge 22, the refraction and extension operation of the small beam 13 is also smooth in this respect.
[0044]
In the above embodiment, an example in which a single membrane material is used as the roofing material 14 has been described. However, as shown in FIG. 7, a double membrane can be used as the roofing material 14. This roofing material 14 is configured so that air does not enter between the double membranes at a portion corresponding to the upper surface of the small beam 13, and air is injected between the left and right small beams 13, and the portion is vertically It is supposed to swell. When the open / close roof 15 is closed, air is injected into the double membrane, while when the open / close roof 15 is opened, the air in the double membrane is discharged. Thereby, when the openable / closable roof 15 is closed, it can be set as a roof with high heat insulation.
[0045]
In this case, the fixing unit 24b described in the embodiment of FIG. 5 and the vertical bar that supports the fixing unit 24b do not exist. 7 is the same as that of the above-described embodiment shown in FIGS. 1 to 6.
In the case of this double membrane structure, a tension applying mechanism that tensions the membrane material is configured by the point where the membrane material is doubled and the configuration in which the membrane material is expanded by air pressure. The shape of the roofing material 14 is maintained by this tension.
[0046]
In the above embodiment, a pair of folding open / close roofs 15 is installed in one opening 26 of the fixed roof 16 so as to be opened as a single opening, whereby the entire opening 26 can be opened and closed. When a pair of open / close roofs 15 are provided in the front-rear direction so as to be double-opened, when the roofs are closed, the large beams 12 forming the moving tips of the both open-close roofs 15 are joined together. For this reason, between the large beams 12 to be bonded, one beam 12 is provided with a ridge reaching the upper surface of the other beam 12, or at least one of the large beams 12 has a rubber weather strip (sealing material). ), The rain between the two beams 12 will be provided.
[0047]
In addition, a lock mechanism is provided so that the connection between the large beams 12 can be maintained until the opening operation of both the open / close roofs 15 is started, and this lock mechanism is interlocked with the driving device of the traveling body 17, It is preferable to release the locking mechanism when the driving device starts driving to open the open / close roof 15.
[0048]
【The invention's effect】
As described above, according to the first aspect of the present invention, when the folding roof is open, the front and rear large beams are structurally independent. Since the length of the large beam increases and the main beam is bent during opening and closing movement, the other large beams are not affected by the bending. In addition, since the small beams are erected independently from each other at a plurality of locations in the longitudinal direction of the large beams, the amount of bending and distortion of the large beams at the hinges in each small beam is negligibly small. The shear force applied to the hinge pin is small. For this reason, since the large beams are allowed to bend and distort, even with an open / close roof with a large span between the left and right travel paths, it is possible to reduce the weight of the steel frame and reduce the weight. There is an effect that the non-tuning of the traveling body is allowed and the control of the driving device of the large beam becomes easy.
[0049]
When the folding roof is closed, the beam is extended to structurally integrate the front and rear beams, and a structural frame is formed by the adjacent beam and a plurality of beams between them. Since the structural frame is formed by restraining the two large beams through the small beams, the structural frame supports the own weight, loading load, wind pressure, etc., and is transmitted to both travel paths, so it is closed. There is also an effect of increasing the strength of the folding roof in the state.
[0050]
Further, according to the invention of claim 2, in addition to the effect of the invention of claim 1, since the girder changes the posture in accordance with the inclination of the traveling road, the folding of the type in which the roof is inclined is provided. When the roof is closed, the angle in the vertical plane between the girder and the girder built between the girder is roughly the same at each position in the running direction, so the structural frame at each position in the front-rear direction The strength can be set to the same level, and the strength of the entire openable roof can be made uniform.
[0051]
Furthermore, according to the invention of claim 3, in addition to the effect of the invention of claim 1, when the opening and closing roof is opened and the interval between the large beams is narrowed, the top is narrowed between the front and rear large beams. On the other hand, the refracted beam has a narrow top and bottom width and a bottom surface and wide bottom surface, so that it can be accommodated in the space between the large beams. Since there is no useless space between the beams, the folding length of the open / close roof can be reduced when the open / close roof is opened.
[0052]
Furthermore, according to invention of Claim 4 and Claim 5, by the tension | tensile_strength provision mechanism of a roof material, tension | tensile_strength is given to the film | membrane material as a roof material, and the shape as a roof material stabilizes by a wind. Flapping is prevented and the flow of rainwater is smooth.
