BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail used for expansion gates, sliding doors and the like.

[0002]

2. Description of the Related Art Two rails having an I-shaped cross section are embedded in a road surface so as to be parallel to the road surface and the top surface of the rail and the road surface are substantially flush with each other, and further inserted from the head of the rail and the gate side. Japanese Patent Publication No. Sho 55-6959 discloses a device for preventing a gate from falling over by engaging a locking claw of a locking plate.

Further, two rails are arranged in parallel with the road surface, and a plurality of rollers are attached in two rows at the lower part of the gate which is movably arranged on the horizontal rail. The structure of mounting the guide rail rising up and engaging the guide rails with the engaging portions respectively attached to the lower portions of the gate is a structure for mounting the gate on the rail.
No. 096.

However, according to the rail structure for the gate of Japanese Utility Model Publication No. 55-6959, the rail is buried in the road surface so that it does not hinder the passage of the vehicle, but the groove has the same material as the road surface. Since it is composed of, the shoulder portion of the groove is gradually worn, and it is not possible to efficiently discharge foreign matter such as earth and sand and dust accumulated inside the groove, and there is a problem that the groove is damaged and the appearance is deteriorated. there were.

On the other hand, in Japanese Utility Model Laid-Open No. 59-126096, the vicinity of the guide rail portion is formed by a rail surface, which improves foreign matter dischargeability, but the guide rail projects upward from the road surface, so that a person or a vehicle Will obstruct traffic.

DISCLOSURE OF THE INVENTION In view of the above-mentioned problems, the present invention is composed of a plate-shaped body having a groove-shaped cross section, and an inclined surface that rises obliquely upward from one side of its central bottom surface to the outside.
A parting edge projecting outward from the upper end of the inclined surface is integrally formed, and an upright surface that rises upward from the other side of the central bottom surface and a projecting edge from the upper end of the upright surface toward the groove side. The engaged surface that engages with the engaging fitting that is inserted from the gate side and the roller running surface that rolls the roller that is attached to the lower part of the gate and that projects outward from the engaged surface are integrally formed. By making the positions of the parting edge and the roller traveling surface substantially the same, the intended purpose is achieved.

[0007]

According to the present invention, the rail for the gate is constituted by the groove-shaped plate, and the gate is prevented from falling down by the engagement of the engaging metal and the engaged surface. Since the inclined surface that rises toward the side is formed integrally with the rail,
Foreign matter in the rail groove can be easily discharged, and since the rail's parting edge and the roller running surface are located at the same height, it does not hinder the passage of people and vehicles.

1 to 4 show an embodiment of a rail for a gate of the present invention, in which 1 is a gate, 2 is a roller, 3 is a rail, and the gate 1 can be of various forms. The present embodiment is applied to a stretchable gate having a pantograph mechanism. Two rails 3 are laid parallel to the road surface 17, and rollers 2 mounted in two rows below the gate 1 roll on the rails 3.

On both lower sides of the trapezoidal frame body 4 constituting the gate 1, pedestals 5 for correcting the mounting angle of the rollers 2 to be parallel to the gate are attached.
A roller support bracket 6 is attached to the outer lower part of the. And the roller 2 has a bush 7 and a bearing 8.
Is rotatably supported by the support shaft 9 via a threaded portion formed at both ends of the support shaft 9, and the middle portion of the support shaft 9 penetrates through the support shaft insertion holes of the frame 4 and the pedestal 5 to The nuts 10 are fastened and fixed to the support bracket 6 at both ends.
Reference numeral 11 in the drawing is a cover made of resin or the like for covering the roller supporting portion.

The rail 3 is formed by integrally bending a plate-shaped stainless steel plate or the like, has a groove shape in cross section, and forms a groove portion 12. An inclined surface 32 is formed which rises obliquely upward from one side of the central bottom surface 31 so that foreign matters accumulated in the groove portion 12 of the rail 3 can be easily discharged. As a result, a parting edge 33, which serves as a guide for the cement mortar finished surface, is formed, and its tip is bent downward.

On the other hand, a central bottom surface 31 is formed with an upright surface 34 that rises vertically from the other side, and an engaged surface 35 is formed horizontally from the upper end thereof toward the inside of the groove 12, and is fixed to the lower portion of the support bracket 6. Engagement fitting 13 having a substantially L-shaped cross section
By locking with the engaging claw 131, the fall of the gate 1 is prevented. A guide surface 36 that rises vertically upward again from the tip of the engaged surface 35 is formed, and the side surface of the large diameter portion 21 formed on one side of the roller 2 is in sliding contact with the side surface of the gate 1 in the width direction. It regulates movement. Guide surface 3
6 A roller running surface 37 is formed which horizontally projects outward from the upper end, and the small diameter portion 22 of the roller 2 rolls. A vertical surface 38 descending from the tip is provided. The parting edge 33 at the upper end of the rail 3 and the roller traveling surface 37 are provided at the same height position.

Explaining the construction mode of the gate rails 3, the two gate rails 3 are joined to the connecting rod 14 by welding or the like on the back surface of the central bottom surface 31 of the two rails 3 at appropriate positions in the longitudinal direction of the rail 3. They are connected to each other in parallel. And the parting edge 33 which is the upper end of the rail 3
The roller rod running surface 37 and the roller running surface 37 are substantially flush with the road surface 17. The connecting rod 14 is fixed to the anchor bolt 15 fixed in the ground, which is set in advance, by the nut 16, so that the parting edge 33 and the roller running surface 37 are substantially flush with the road surface. Cement mortar finish is performed so as to be flush. Next, the roller 2 of the gate 1 is placed on the roller traveling surface 37 so as to be aligned with the guide surface 36, and the engaging claw 131 of the engaging metal fitting 13 is engaged with the roller supporting bracket 6 so as to engage with the engaged surface 35. The fitting 13 is fixed with bolts or the like.

[0013]

[Effect of the Invention] According to this invention, the rail 3 is prevented from falling, and the rail 3 is integrally formed by a plate-like member.
Since the inclined surface 32 that rises outward from one side of the central bottom surface 31 is provided, foreign matter such as earth and sand and dust accumulated in the groove portion 12 of the rail 3 can be easily discharged, and the parting edge 33 and the roller running. The surface 37 is buried in the road surface so as to be substantially flush with the road surface to avoid obstacles for people and vehicles to pass through and to endure long-term use.
