[Industrial applications]

 The present invention relates to a winding device for a film body such as a light-shielding film.

[0002]

[Prior art]

 As a wind-up device that opens and closes the light-shielding film inside the glass window of the building, one end of the light-shielding film is connected to the outside of the winding shaft to which a rotating force is applied in the winding direction by a coil spring. The applicant of the present application has applied a tension in the width direction to the light-shielding film pulled out from the winding shaft so that the light-shielding film can be stopped and held at an arbitrary position pulled out from the winding shaft. I have already proposed.

In the above winding device, a pair of square tubular side frames are connected to both ends of a roll storage case that stores a winding shaft for applying tension to the light-shielding film, and are guided to the inner surfaces of the side frames facing each other. A groove is formed, and a guide groove for guiding the movement of both side edges of the light-shielding film is formed on the inner rail of the rectangular tube incorporated inside the side frame, and flanges provided on both sides of the inner rail are made of elastic material. Then, the bent pieces on both sides of the guide groove are engaged with the engaging ridges provided on both sides of the light shielding film to stretch the light shielding film in the width direction.

In the winding device having the above structure, the light shielding film to which a pulling force in the winding direction is constantly applied by the frictional force acting on the inner rail and the engaging portion of the engaging protrusion is held. Therefore, there is an advantage that the light-shielding film can be opened and closed very easily and can be opened and closed with a light force.

[Problems to be solved by the device]

 In recent years, it has been attempted to improve the comfort of a tourist bus by providing an opening on the curved ceiling surface, and attaching a curved glass plate that is fitted to the opening to improve the lighting inside the vehicle. There is.

Further, even in the case of a Shinkansen vehicle, there is an idea that the window glass on the side surface is extended to both corners of the ceiling to widen the field of view and improve the view in order to improve comfort.

In the vehicle as described above, sunlight incident from the curved glass plate may cause discomfort and adversely affect comfort.

Therefore, if the curved glass plate is opened and closed from the inside by the light-shielding film of the winding device, the inconvenience as described above can be solved. In this case, however, the side frame of the winding device is removed. It is necessary to make each of the inner rail and the inner rail curved along the curved surface of the glass plate, which causes a problem of high manufacturing cost.

In order to solve the problem, only the side frame is curved along the curved surface of the glass plate, the inner rail is extruded from a flexible synthetic resin material, and the inner rail is assembled inside the side frame. By following the shape of the side frame with, it is possible to reduce the cost.However, the inner rail has flanges on both sides, so it cannot be easily deformed. However, there is a problem that the light-shielding film cannot be opened and closed smoothly.

The present invention has a technical object to provide a low-cost winding device capable of smoothly opening and closing a film body such as a light-shielding film along a curved surface.

[0011]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, a winding shaft is provided inside a roll storage case having a film body outlet, and both side edges of the film body wound on the winding shaft are wound. Providing engaging ridges that can be wound in a winding shape, guide grooves are formed on the inner facing surfaces of a pair of rectangular tubular side frames connected to both ends of the film body outlet of the roll storage case. On the inner side of the square tubular inner rail, guide grooves are formed to guide the movement of both side edges of the film body, and a pair of flanges are provided on both sides of the inner rail. The elastic body for pressing the bent pieces on both sides of the guide groove to the engaging ridges of the film body is installed inside the side frame, and both ends of the film body are guided by the guide groove. In a winding device with a guided operation frame attached, a curved surface to which the winding device is attached to the side frame. The inner rail built into the side frame is made of a flexible material, and is attached to the inner rail in the length direction of the inner rail with respect to the length direction of the inner rail. We adopted a structure in which intersecting slits were formed at the required intervals.

[0012]

[Action]

 As described above, by forming the slits on the flange of the inner rail at the required intervals, the inner rail is easily bent, and when inserted inside the side frame, the inner rail follows the shape of the side frame. The guide groove is extremely small and the movement of the membrane is smoothly guided.

A pair of flanges 11 are provided on both sides of the inner rail 9. As shown in FIG. 3, the flange 11 is pushed outward by the elastic body 12, and the bent pieces 13 on both sides of the guide groove 10 are engaged with the engaging ridges 7 of the film body 6 to cause the film body 6 to move. The tension in the width direction is applied to.

The inner rail 9 is made of a synthetic resin extruded product and has flexibility. As shown in FIG. 6, the inner rail 9 has a length in the longitudinal direction of the flanges 11 on both sides. Slits 14 intersecting with each other are formed at a required interval.

The formation of the slits 14 facilitates the inner rail 9 to be deformed in the width direction as shown in FIG. 8, and the inner rail 9 is shaped into the side frame 2 at the time of assembly for insertion into the curved side frame 2. Deforms easily along. At this time, the deformation of the guide groove 10 is extremely small and does not hinder the movement of the film body 6.

An operation frame 15 is attached to the tip of the film body 6, and both ends of the operation frame 15 are slidably inserted into the guide grooves 8 of the side frame 2.
