Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing moving portion structure of an opening / closing roof for opening and closing an opening formed in a fixed roof by moving a movable roof.

[0002]

2. Description of the Related Art Opening and closing roofs are disclosed, for example, in Japanese Patent Laid-Open No. 10-299.
As disclosed in JP-A-155-155, a movable roof moves and opens and closes an opening formed in a fixed roof. At this time, the movable roof can be moved smoothly by rolling wheels provided on both ends of the movable roof on rails provided on both sides of the opening.

Meanwhile, a movable roof conventionally used has a movable roof 1 curved upward and an arch structure as shown in FIG. 7 (a) or a flat flat structure as shown in FIG. 7 (b). There is a movable roof 2. These movable roofs 1, 2
May be supported by a movable roof support member 4 such as a keel arch or a structural beam of a fixed roof 3 as shown in FIG. 8, or may be supported by columns and beams of a watching stand (not shown). The fixed roof 3 is constructed as a dome roof,
In FIG. 8, the entire opening / closing roof is shown as an elliptical shape, and the opening 5 opened and closed by the movable roofs 1 and 2 is formed in the longitudinal direction of the opening / closing roof.

[0004]

However, in the conventional openable roof, the movable roof 1 having the arch structure has a structure shown in FIG.
As shown in (a), a deformation force acts in the opening direction due to its own weight, an outward thrust force F1 is generated at both ends, and the movable roof 2 having a flat structure is shown in FIG. As described above, a deformation force acts in a direction in which the central portion hangs down, and an inward tensile force F2 is generated at both ends. Therefore, a horizontal force such as the thrust force F1 or the tensile force F2 acts on the movable roof support member 4 that supports both ends of the movable roofs 1 and 2. Further, a similar force acts due to a change in environmental temperature or a blowing force or a blowing force due to wind.

That is, when the thrust force F1 acts on the movable roof support member 4 of the arched movable roof 1, the movable roof support member 4 moves laterally in the direction of increasing the width of the opening 5, and the lateral movement causes the movable roof support member 4 to move. The roof 1 is further greatly deformed in the opening direction. When the movable roof 1 is further opened and deformed in this way, the stress of the structural members constituting the movable roof 1 increases greatly. Further, as shown in FIG. 8, when the plurality of movable roofs 1 move, the thrust force F1 is gathered in a portion P where a plurality of movable roofs 1 are close to each other, as shown in FIG. It becomes large and becomes small in the portion Q where the single sheet is separated. For this reason, when the rigidity of each member is to be minimized in accordance with the demand for the weight reduction of the fixed roof 3 and the movable roof 1, it is necessary to accurately grasp the deformation amount of the movable roof 1 and the stress of the structural members. Becomes significantly more difficult. When the fixed roof 3 and the movable roof 1 are lightened in such a situation, unexpected deformation and excessive stress occur, and the wheels of the movable roof 1 are mounted on the movable roof support member 4 by rails (not shown). There is a risk that the wheel will be removed from the vehicle.

Further, even with the movable roof 2 having a flat structure, the movable roof support member 4 is laterally moved in the direction of narrowing the width of the opening 5 by the tensile force F2 generated at both ends. As in the case of the movable roof 1 described above, there is a problem that it becomes extremely difficult to grasp the deformation amount and the member stress of the movable roof 2 having the flat structure.

In view of the foregoing, the present invention has been made in view of the above-mentioned conventional problems, and absorbs the lateral movement deformation of the movable roof support member to prevent the movable roof from moving at the support point. By keeping the horizontal force acting on the support member constant, the movable roof can be smoothly opened and closed even when the roof is lightened by keeping the deformation and the member stress of the movable roof at a constant value. An object of the present invention is to provide an opening / closing moving structure of an opening / closing roof.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, an opening / closing moving portion structure of an opening / closing roof according to the present invention comprises a movable roof movable between opposing sides of an opening formed in a fixed roof. In the openable / closable roof to be arranged, a support member of the movable roof has a horizontal direction regulating member for preventing the movable roof from moving in the side direction of the opening, and a vertical direction supporting a load of the movable roof. A restricting member, and the horizontal restricting member is provided with a displacement allowable gap allowing relative displacement in the restricting direction, and the displacement allowable gap has a load constant region in which a load variation is substantially constant with respect to a deformation amount. A spring member having the above-mentioned spring characteristics is interposed.

According to this structure, the movable roof is opened and closed along opposing sides of the opening while being restricted in position by the horizontal direction regulating member and the vertical direction regulating member. When a horizontal force acts on the supporting portion in the side direction of the opening, and both sides of the opening laterally move, the lateral movement of both sides is absorbed by deformation of the spring member interposed in the displacement allowable gap. In addition, the support point of the movable roof can be prevented from moving. Further, since the spring member has a spring characteristic in a constant load area, the horizontal force exerted on the fixed roof from the movable roof is kept constant, and the relative position between the horizontal regulation member and the vertical regulation member and the fixed roof changes. Can be prevented. Therefore, even when the deformation and the member stress of the movable roof are applied according to the originally designed values in order to reduce the weight of the roof, the movable roof is smoothly opened and closed without falling off or falling off.

The basic structure of the opening / closing moving portion structure of the opening / closing roof according to the present invention is such that movable roofs 12 and 14 are movably arranged across opposing sides of an opening 18 formed in a fixed roof 16. In the opening and closing roof 10, the movable roofs 12, 1
A supporting member 26 for preventing the movable roofs 12 and 14 from moving toward the side of the opening 18 and a vertical direction supporting the load on the movable roofs 12 and 14. In addition to the restriction member 34, the horizontal restriction member 32 is provided with a displacement allowable gap δ that allows relative displacement in the restricting direction. The spring member 52 having the spring characteristic S of the constant load region R is interposed, and the relative displacement portion of the displacement allowable gap δ is elastically supported by the constant load region R of the spring member 52.

That is, as shown in FIG. 1, the openable roof 10 having the openable / closed moving section structure of the present embodiment has movable roofs 12, 1 as shown in FIG.
4 shows a case where four movable roofs 1 are arranged in upper and lower stages.
The fixed roofs 2 and 14 have the same structure and are supported on the fixed roof 16 side, and open and close an opening 18 formed in the fixed roof 16. The fixed roof 16 is provided with vertical walls 20 along both sides of the opening 18. On the inner surface of the vertical wall 20, shelves 22 and 24 are horizontally provided in two vertical stages. The combination of 22, 24 is the opening 1
8 are arranged. Each shelf 22,2
The movable roofs 12 and 14 are movably supported on the upper surface of the support 4 via support portions 26, respectively.

Each of the support portions 26 of the movable roofs 12 and 14 has the same configuration, one of which is shown in FIGS. The support portion 26 includes a support portion main body 30 for attaching an end portion of the roof main body 28 configured as a truss structure shown in FIG. And a vertical wheel 34 as a vertical restriction member provided below the support body 30. The horizontal wheel 32 and the vertical wheel 34 are each a set of two, and each is rotatably attached to the wheel support members 36 and 38. The central portions of the wheel support members 36, 38 are respectively attached to pins 44, 46 by brackets 40, 42 projecting from the side and below the support portion main body 30, respectively.
It is attached rotatably via.

Here, the bracket 40 to which the horizontal wheels 32 are attached is attached to the support body 30 by bolts 48.
Attached so as to be relatively movable through. That is, the bracket 40 has a bolt 48 slidably inserted into the center of the bracket 40 and locked to the head 48a thereof, and a displacement allowable gap δ is provided between the bracket 40 and the support body 30. The screw portion 48 b of the bolt 48 is fixed to the support portion main body 30 with a nut 50. This allows the bracket 40 to move relative to the support portion main body 30 together with the horizontal wheel 32 within the range of the displacement allowable gap δ.

A disc spring 52 as a spring member is inserted through the bolt 48 in the displacement allowable gap δ.
The disc spring 52 allows the bracket 40 to move the support body 3
It is pressed in a direction away from 0 and is resiliently supported. In the present embodiment, four disc springs 52 are used, and these disc springs 52 are alternately arranged on the front and back sides between adjacent ones. The disc spring 52 has a non-linear spring characteristic S shown in FIG. 6, has a constant load region R where the variation of the load P is substantially constant with respect to the deformation amount x, and is interposed in the displacement allowable gap δ. In this state, the disc spring 52 is set in the constant load region R.

The vertical wall 20 and the shelves 22, 24
The first rails 54 and the second rails 56 are continuously arranged along both sides of the opening 18 at positions corresponding to the horizontal wheels 32 and the vertical wheels 34, and the horizontal wheels 32 contact the first rails 54. While rolling in contact with the second rail 5
The vertical wheel 34 comes into contact with 6 and rolls. When the horizontal wheels 32 abut on the first rails 54, both sides of the opening 18 of the movable roofs 12 and 14 (left and right directions in FIG. 1).
And the vertical wheels 34 contact the second rail 56 to support the loads on the movable roofs 12 and 14.

The wheel support member 36 is provided with a flange 58 at a central portion on the side facing the vertical wall 20, while the vertical wall 20 has a pair of L-shaped engagement with the flange 58. The stopper 60 is fixed so as to sandwich the wheel support member 36 from both sides, thereby preventing the horizontal wheel 32 from moving away from the first rail 54. Similarly, a flange portion 62 is provided at the center of the wheel supporting member 38 on the side of the shelf plates 22 and 24, and a pair of Ls engaged with the flange portions 62 on the shelf plates 22 and 24.
The character-shaped stopper 64 is fixed to prevent the vertical wheel 34 from floating.

With the above construction, in the opening / closing moving section structure of the opening / closing roof of the present embodiment, the movable roofs 12, 14 move by connecting driving means (not shown), for example, a rope wound around a winch. Thus, the opening 18 can be opened and closed. When the movable roofs 12 and 14 move, the horizontal wheels 32 abut on the first rails 54 and roll, thereby restricting the position of the opening 18 on both sides, and the vertical wheels 34 move the movable roofs 12 and 14. The second rail 56 rolls while supporting the load.

Accordingly, when a horizontal force such as a thrust force or a tensile force acts on both ends of the movable roofs 12 and 14, the horizontal force acts in a direction in which the horizontal wheels 32 press the first rail 54 or in a direction in which the first wheels 54 are separated. I do. At this time, in the present embodiment, since the disc spring 52 is interposed with the displacement allowable gap δ provided, the horizontal force for laterally moving the first rail 54 is such that the displacement allowable gap δ is relatively large while the disc spring 52 is deformed. It is absorbed by the displacement (change in interval of δ). Further, since the spring characteristic of the disc spring 52 is set in the constant load region R, it is possible to maintain a constant horizontal force acting on both sides of the opening 18 from the movable roofs 12 and 14, that is, the vertical wall 20. it can.
Therefore, even when the deformation and the member stress of the movable roofs 12 and 14 are performed while maintaining the initial design values, the vertical wheels 34 do not change their positions in both side directions of the opening 18.
The vertical wheel 34 keeps rolling on the second rail 56 without derailing, and moves the movable roofs 12 and 14 smoothly.

Further, the provision of the disc spring 52 makes it possible to effectively absorb horizontal vibrations caused by an earthquake. At this time, as shown in FIG.
And a viscous damping member 7 such as an oil damper
By setting 0, seismic vibration can be attenuated by the viscous damping member 70.

In this embodiment, the movable roof 12,
Although 14 is configured in two steps, the present invention is not limited to this, and it is needless to say that the present invention can be applied to a movable roof having one or three or more steps.

Further, although the case where four disc springs 52 are used is shown, the number of disc springs 52 can be arbitrarily determined according to the allowable supporting force of the disc springs 52 without being limited to this number.
At this time, the spring member is not limited to the disc spring 52, and any type of spring, such as a coil spring or a leaf spring, may be used as long as the constant load region R is provided.

Further, the case where the horizontal wheel 32 and the vertical wheel 34 are used as the horizontal direction restricting member and the vertical direction restricting member has been shown. However, instead of these wheels, a sliding member or a roller member using a bearing is used. Can also be configured.

[0024]

As described above, in the opening / closing moving portion structure of the opening / closing roof according to the present invention, the spring member having the constant load area is interposed in the displacement allowable gap provided in the horizontal direction regulating member. The horizontal forces acting on the opposite sides of the part are absorbed by the deformation of the spring members, which can prevent the support points of the movable roof from moving. Further, since the spring member uses a spring characteristic in a constant load area, the horizontal force exerted on the fixed roof from the movable roof is kept constant, and the relative position between the horizontal direction regulating member and the vertical direction regulating member and the fixed roof changes. Can be prevented. Therefore, even if the deformation and the member stress of the movable roof are applied as originally designed to reduce the weight of the roof, the movable roof can be prevented from falling off and falling, and can be smoothly opened and closed. It has an excellent effect that it can be done.
