Description

  The present invention relates to a laying rail device that can be used as a guide rail for a movable rack that is installed to be laterally movable on a floor surface.

A laying rail device used as a guide rail for a moving rack is a belt-like rail body laid on the floor surface, and is disposed on both the left and right sides of the rail body to fill a step between the floor surface. It is comprised from a slope formation part. Thus, as a well-known laying rail device of this type, as shown in Patent Document 1, on the left and right sides of the rail body fixed on the floor surface with anchor bolts, slope forming portions made of resin mortar are constructed on site. As shown in Patent Document 2, a separate slope forming member manufactured separately from the rail body is placed on the floor on both the left and right sides of the rail body fixed with anchor bolts on the floor surface. There are known ones that are fixed on the surface with a fastening tool such as a concrete screw.

  In the type of on-site construction of the slope forming part as shown in Patent Document 1, it is expensive because it requires preparation and construction of resin mortar on site by a plasterer who has acquired mortar construction technology. There are also problems such as the generation of off-flavors and the need for a certain curing period. Moreover, in the type which attaches the slope forming member of another part as shown in patent document 2, the problem in the type which constructs the slope forming part in the field is solved, but the rail main body side of the slope forming member of another part is eliminated. Since it is configured to position the slope forming member with respect to the rail body by bringing the side edge into contact with the side edge of the rail body, when configuring a rail device for supporting and guiding the hooked wheel, By fixing the side of the slope main body side of the slope forming member on the floor surface with a certain distance from the side of the rail main body, the flange of the hooked wheel is provided between the rail main body and the slope forming member. The loose groove part to be loosely fitted must be formed, and not only is it troublesome to position the slope forming member when fixing the slope forming member on the floor surface, It has been difficult to the flange portion of the feeder wheel to ensure precisely the width of the groove portion to be loosely fitted.

  An object of the present invention is to provide a laying rail device that can solve the above-described various problems, and the laying rail device according to claim 1 refers to an embodiment described later. When shown with a reference numeral, it is a rail device laid on the floor surface 3, which is a strip plate-like rail body 7, and is arranged on the floor surface 3 on both the left and right sides of the rail body 7, and the rail body In the laying rail device composed of slope forming members 9A and 9B that fill the step between the floor surface 3 and the floor surface 3, the rail body 7 and the slope forming members 9A and 9B are each composed of separate parts fixed on the floor surface. Further, thin-shaped tongue pieces 8a and 8b that are in contact with the floor surface from either one of the rail body 7 and the slope forming members 9A and 9B, integrally extend to the other side and abut on the other side surface are continuously provided. The thin-walled tongue pieces 8a and 8b Rail body 7 and the slope forming member 9A in the upper, has a configuration in which recessed groove 11 is formed between the 9B.

  In carrying out the present invention according to the first aspect, specifically, as described in the second aspect, the thin-walled tongue pieces 8a and 8b are continuously provided from the slope forming members 9A and 9B. Slits 12 are formed in the rail width direction at appropriate intervals in the rail length direction of the slope forming members 9A, 9B with the tongue-like tongue portions 8a, 8b, and the slits 12 are divided into a plurality of pieces in the rail length direction. Further, each of the sections 13 of the slope forming members 9A, 9B can be connected to each other via the thin-walled connecting portions 8a, 8b.

  Further, as described in claim 3, the thin tongue portions 8a and 8b are connected to the slope forming members 9A and 9B, and the slope forming members 9A and 9B with the thin tongue portions 8a and 8b are connected. It can be molded integrally with a synthetic resin.

  According to the laying rail device according to the first aspect of the present invention, the rail main body and the slope forming members on both the left and right sides thereof are configured as separate parts, and they are only fixed separately on the floor surface. The rail device can be constructed with a rail device with a slope forming member that can be easily and inexpensively laid by a general worker who does not have special technology such as plastering technology. Problems such as divergence and a certain period of curing are also eliminated. In addition, the positional relationship between the rail body and the slope forming member is determined simply by bringing the tip of the thin tongue piece continuous from either of them into contact with the other side. Since the groove portion that matches the width of the thin tongue portion can be automatically secured between the member and the member, the flange portion of the hooked wheel is loosely fitted between the rail body and the slope forming member. A highly accurate rail device having a groove with a constant width can be configured easily and easily.

  In addition, although the said thin-walled tongue piece part can also be continued from the rail main body side, according to the structure of Claim 2, when the width | variety of a slope formation member is enough and the slope formation part of a gentle inclination is comprised Even when the flat surface accuracy of the floor surface is poor, the slope forming member is divided in the rail length direction, so that each divided section of the slope forming member is individually brought into surface contact with the floor surface, A stable rail device without sticking can be obtained. In addition, since the divided sections of the slope forming member are connected and integrated with each other via the thin tongue portion, the entire slope forming member can be easily and easily arranged at a predetermined position on the floor surface. The fixing work of the forming member on the floor surface can be easily performed.

  Furthermore, since the rail body requires high load bearing performance and wear resistance performance, it is preferable that the rail body is made of a metal material. In this case, according to the configuration of claim 3, the thin tongue portion is integrated. Since the slope forming member prepared in the above can be formed of synthetic resin, the thin tongue portion and the slope forming member can be easily formed and can be implemented at low cost.
