Therefore, in consideration of Japanese Utility Model Publication No. 58-8853 (Japanese Patent Application No. 52-160930), the present applicant has proposed a folding type gate device, and Japanese Utility Model Publication No. 55-33038 (Japanese Patent Application No. 54-123399). ) And Japanese Utility Model Publication No. 54-5554 (Japanese Patent Application No. 49-50735), which is composed of a main door and a plurality of sub-doors, and these doors can be overlapped by traveling on the same rail. I proposed the gate device which was made.

[0003]

[Problems to be solved by the device]

 However, in the case of such a conventional gate device, since the respective doors are configured to be overlapped with each other, a step is generated between the sub doors and a large step is generated between the main door and the most advanced sub door. However, in terms of appearance, the frontage could not be closed in a row in a row, and it was not sufficient in terms of strength. Therefore, unlike the conventional device, the present invention does not cause the doors to overlap each other even when they are retracted, and there is no step between the doors. Therefore, the door can be easily opened and closed, and the retracting place is defined as the frontage. Allows the two sides to be used, for example, in a corner, by pulling them into different places, that is, at positions that intersect with the frontage. Furthermore, it aims at providing what is excellent also in intensity | strength than the conventional thing.

[0004]

Means for Solving the Problems That is, the present invention provides a gate main body in which a plurality of doors are pivotally mounted so as to swing horizontally with respect to each other, and below the pivot shaft of the door or both ends of the gate main body. A bogie frame pivotally attached to the lower end of the door located at, and a guide rail having a recessed groove embedded in the ground surface, and the bogie frame in which the bogie is pivotally attached vertically to the door, Floating wheels attached to both ends of the frame, and two horizontally rotating guides pivoted in the direction from the center of the bogie frame below the idler wheels through a fixture in a direction intersecting the longitudinal direction of the bogie. The guide rail is formed in an arc shape so that one end of the guide rail is positioned perpendicular to the frontage, and the two guide rollers of each of the carriages are fitted in the groove of the guide rail. Achieve this objective with the inserted gate device . According to a second aspect of the present invention, the opening width is narrowed by locking pieces that are provided in the guide rail so as to connect all or part of the recessed groove opening portion from both peripheral edges toward the center. According to a third aspect of the present invention, a fitting for connecting the bogie frame and the guide roller is fixed to the lower center of each bogie in a direction intersecting the longitudinal direction of the bogie, and both ends of the bearing fitting. It is composed of two shafts that are vertically lowered from According to a fourth aspect of the present invention, rails having a brim portion parallel to the guide rail are embedded in both sides of the mounting guide rail in the bogie frame, and the brim portion and a cross section fixed to both sides of the bogie are provided. It is configured to slide with the L-shaped locking piece. According to the invention of claim 5, since the doors are pivotally attached to each other so that when the doors move on the linear guide rails, one end of one door is formed so that the doors are linear. A reinforcing plate is fixedly attached to the part so that it comes into contact with the adjacent door.

[0005]

[Action]

 In the gate device according to the present invention, the gates made up of a plurality of doors are arranged in a line to open and close the frontage. Wheels are provided and two guide rollers are fitted into the groove of the guide rail. As a result, since the carriage and the door are guided by the two guide rollers and the angle of the carriage with respect to the door of the carriage is changed by the position of the guide roller, the carriage is always perpendicular to the tangential direction of the guide rail. It will be in a state of intersecting. Also, although part of the guide rail is formed in an arc shape, the guide roller mounted below the carriage slides along the groove of the guide rail, and the guide wheel rotates parallel to the tangential direction of the guide rail. As a result, the gate can be moved smoothly. Furthermore, since one end of the guide rail is configured to be perpendicular to the frontage, it is possible to find the door's retracted part in the depth direction even in a house with a narrow frontage, and On the other hand, even if the frontage is less than 1.5 times, it corresponds. If the guide rail is provided with a locking piece in the groove, the diameter will be smaller than the diameter of the guide roller installed in the fixture, so the carriage will not come off the guide rail and the Since the locking piece and the guide roller are in sliding contact with each other, the force of falling is suppressed. Further, in the invention in which the reinforcing plate is fixed, when the arc-shaped guide rail is moved, the fixed reinforcing plate does not come into contact with the door, and only when the linear guide rail is moved, the adjacent door and the reinforcing plate are Abut. Therefore, when an external force is applied to one of the doors in front of the gate without affecting the opening and closing of the gate, the force applied to that door is dispersed to the adjacent doors, and the strength of the entire gate is reinforced. You will be competing.

[Embodiment of device]

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. 1 to 4, 1 is a gate main body, 2 is a trolley, 3 is a guide rail, and the gate main body 1 has a plurality of doors 1a, 1b, 1c ... They are pivotally attached to each other. Various structures can be adopted for the pivotal attachment means of the door, but in this embodiment, bearings 4, 4 having a U-shaped cross section are fixed above and below the side end portions of the doors 1a, 1b ... 1n, respectively. Each door is pivotally attached by a shaft 5 penetrating the overlapping part of the doors. In this embodiment, the carriage 2 is pivotally mounted on the bearing 4 below the door (eg, 1a) on the left side of the figure so as to be orthogonal to the surface of the door. As shown in FIG. 3, the dolly 2 includes a dolly frame 2a, idler wheels 6 and 6 mounted on the lower ends of both ends of the dolly frame 2a, and a lower portion of the dolly frame 2a from a center of the dolly frame 2a through a fixture 8 below the wheels. It is composed of a guide roller 7 pivotally attached to the. In this embodiment, as shown in FIG. 4 and FIG. 5, the fixture 8 is fixed in the direction perpendicular to the carriage 2 from the center of the bottom of the carriage frame 2a, and is bent vertically in the middle of the end. And a shaft 8b, 8b pivotally attached to the horizontal parts of both ends of the bearing metal 8a. The disk-shaped guide rollers 7, 7 are attached to the shaft 8b, 8b. It is installed. The diameter of the guide roller 7 is smaller than the inner diameter of the opening groove of the guide rail 3, and the clearance allows the guide roller 7 to smoothly slide on the arc-shaped guide rail 3. Guide the movement of the gate along the rail 3.

The guide rail 3 has a recessed groove that is embedded in the surface of the earth and opens upward, and the guide rollers 7 and 7 are fitted into the recessed grooves of the guide rail 3 and along the groove. And travels as the gate body 1 moves. In the figure, 9 is a locking piece that is continuously provided from both edges of the upper opening groove of the guide rail 3 toward the center, and the locking piece 9 narrows the width of the groove. Prevent 7 from rising. These locking pieces 9 can be continuously provided on the periphery of the guide rail 3 or can be intermittently provided at a predetermined interval (narrower than the diameter of the guide roller).

In another embodiment shown in FIG. 6, rails 11 each having a flange portion 10 parallel to the guide rail 3 are buried on both sides of the guide rail 3, and the rail 11 is embedded in the rail 11. The collar 10 and the locking pieces 12 having an L-shaped cross section provided on both sides of the carriage 2 are engaged with each other and slide. FIG. 7 shows another embodiment of the structure of the gate, in which one end of the reinforcing plate 14 is fixed to the upper end portion of the door 1b by welding or the like, and the other end is the frame of the adjacent door (for example, 1a). When the reinforcing plate 14 is joined to the front side of the gate, the reinforcing plate 14 is in contact with an adjacent door in a straight state, and the guide rail 3 is not adjacent to a curved door. It is configured to be in a separated state. Therefore, in the gate door of the present embodiment, all the reinforcing plates 14 contact the adjacent doors in the straight state with the frontage closed, so that the external force applied to some doors can be dispersed to the adjacent doors.

The gate body 1 of the present invention can be moved by traveling on the surface of the ground by the wheels 6 of the carriage 2, and at the time of the movement, even if the guide rail 3 forms a curve, the doors 1a, 1b ... 1n are pivotally mounted so as to swing horizontally, and guide rollers 7 and 7 running in the guide rail 3 are present in the lower part of the carriage 2 and the carriage 2 is located below. By being pivotally mounted below the bearing or the door, it is possible to move along the guide rail. At this time, the carriage 2 is pivotally mounted so as to rotate in the horizontal direction independently of the swing of the doors 1a, 1b ... 1n, but the carriage 8 is fixed to the fixture 8 fixed below the carriage 2. Since the inner rollers 7, 7 are pivotally attached, the carriage 2 is always located in a direction intersecting with the line connecting the pair of guide rollers 7, 7 (tangential line of the guide rail 3). The wheels 6 mounted below the carriage 2 rotate in the tangential direction of the guide rails, so that the sliding friction resistance of the wheels 6 and 6 is suppressed as much as possible.

[Effect of device]

 As described above, according to the present invention, one end of the guide rail is configured to be perpendicular to the frontage, and it is possible to install a gate of a type that does not overlap even on a land with a narrow frontage. In addition, a wheel provided below the bogie that horizontally swings independently of the door, and two guide rollers pivotally attached to both ends of a fixture fixed to the bogie, follow the guide rail. Since the vehicle is configured to travel (parallelly), even if the guide rail has an arc-shaped curve, the wheels can be rotated without resistance and the gate can be opened and closed smoothly. Further, in the structure in which the locking plate for narrowing the gap between the opening grooves is continuously provided on the guide rail, the force of the door falling can be resisted by the sliding contact between the locking plate and the guide roller. . Furthermore, if a reinforcing plate is attached to one end of the door, it will not be an obstacle when traveling on an arcuate rail, and when the doors are arranged in a straight line on a linear guide rail, the reinforcing plate will be adjacent to the adjacent door. Since it abuts and acts so as to maintain a straight state, it is possible to disperse the force applied from the front direction to a part of the gate, and it is possible to provide an excellent strength.
