Abstract

A guide rail that is provided in a track and is brought into contact with a guide wheel of a vehicle to restrict a rolling direction of a running wheel of the vehicle, to thereby guide the vehicle along the track, includes: a rail that comprises a guide portion formed with a guide rail surface with which the guide wheel is brought into contact; and a vibration-isolating member that is provided so as to be in contact with a back surface of the guide rail surface of the guide portion.

Claims (35)

1. A guide rail that is provided in a track and is brought into contact with a guide wheel of a vehicle to restrict a rolling direction of a running wheel of the vehicle, to thereby guide the vehicle along the track, comprising:

a rail that includes a guide portion formed with a guide rail surface with which the guide wheel is brought into contact and formed with a back surface on an opposite side thereof;

a vibration-isolating member that is provided so as to be in contact with the back surface of the guide portion; and

a fixation unit that fixes the vibration-isolating member by pressing against the back surface,

wherein the fixation unit comprises a bolt and a nut,

wherein the bolt is fixed to the back surface and runs through the vibration-isolating member in a direction normal to the back surface,

wherein the nut is screwed on the bolt so as to tighten the vibration-isolating member onto the back surface,

wherein a through-hole through which the bolt is inserted penetrates the vibration-isolating member, and

wherein a small-diameter hole with a diameter larger than that of the through-hole is formed at a base on a back surface side of the through-hole end facing the back surface of the guide portion, wherein the small-diameter hole accommodates a swell-out portion by deformation of the vibration isolating member.

2. The guide rail according to claim 1 ,

wherein the rail further comprises a support portion that supports the guide portion, and

wherein the vibration-isolating member is provided so as to be in contact with a side surface of the support portion.

3. The guide rail according to claim 2 , wherein an angle portion of the vibration-isolating member that faces an intersection portion between the back surface and the side surface is chamfered.

4. The guide rail according to claim 2 , wherein the vibration-isolating member includes a chamfered surface, and the chamfered surface is spaced apart from an intersection portion between the back surface and the side surface to form a space therebetween so that the space is defined by the chamfered surface, the back surface and the side surface.

5. The guide rail according to claim 1 , further comprising

a plate that is provided so as to sandwich the vibration-isolating member between the guide portion of the rail and the plate,

wherein the nut presses the vibration-isolating member against the rail via the plate.

6. The guide rail according to claim 1 ,

wherein the vibration-isolating member is provided so as to run along a longitudinal direction of the rail, and

wherein a plurality of the fixation units are disposed in a staggered arrangement so as to be displaced in a direction orthogonal to the longitudinal direction.

7. The guide rail according to claim 1 ,

wherein an adhesion layer made from an adhesive material is formed between the vibration-isolating member and the rail.

8. A new transit system comprising the guide rail according to claim 1 .

9. The guide rail according to claim 1 , wherein the vibration-isolating member has said swell-out portion entering in the small-diameter hole when the vibration-isolating member is pressed and deformed by the fixation unit.

10. The guide rail according to claim 9 , wherein the vibration-isolating member has a large-diameter hole with a diameter larger than that of the small-diameter hole formed at a terminal end opposite to the base end of the through-hole.

11. A guide rail that is provided in a track and is brought into contact with a guide wheel of a vehicle to restrict a rolling direction of a running wheel of the vehicle, to thereby guide the vehicle along the track, comprising:

a rail that comprises a guide portion formed with a guide rail surface with which the guide wheel is brought into contact and formed with a back surface on an opposite side thereof, and a support portion for supporting the guide portion;

a vibration-isolating member that is provided so as to be in contact with the back surface of the guide portion and with a side surface of the support portion; and

a fixation unit that fixes the vibration-isolating member by pressing against the side surface,

wherein the fixation unit comprises a bolt and a nut,

wherein the bolt is fixed to the side surface and runs through the vibration-isolating member in a direction normal to the side surface,

wherein the nut is screwed on the bolt so as to tighten the vibration-isolating member onto the side surface,

wherein a through-hole through which the bolt is inserted penetrates the vibration-isolating member, and

wherein a small-diameter hole with a diameter larger than that of the through-hole is formed at a base on a back surface side of the through-hole end facing the back surface of the guide portion, wherein the small-diameter hole accommodates a swell-out portion by deformation of the vibration isolating member.

12. The guide rail according to claim 11 , wherein the vibration-isolating member has said swell-out portion entering in the small-diameter hole when the vibration-isolating member is pressed and deformed by the fixation unit.
