## Abstract

A passenger conveyor includes a main frame, a support angle at an end in a longitudinal direction of the main frame and which is to be disposed on a building structure; and a support reinforcement part. The support reinforcement part includes a connection portion which is fixed to the support angle, a building-side extension portion which is extended from the connection portion along a floor face of the building structure, and a main-frame-side extension portion which is extended from the connection portion along an upper face of the main frame. In a case where the building-side extension portion of the support reinforcement part is in contact with the building structure, and the support angle is not in contact with the building structure, at least one portion of the main-frame-side extension portion is able to touch the upper face of the main frame.

## Claims

### Claim 1

A passenger conveyor comprising:
a main frame;
a support angle which is provided at an end in a longitudinal direction of the main frame and which is to be disposed on a building structure;
a support reinforcement part comprising
a connection portion which is fixed to the support angle,
a building-side extension portion which is extended from the connection portion along a floor face of the building structure, and
a main-frame-side extension portion which is extended from the connection portion along an upper face of the main frame,
wherein the main-frame-side extension portion is not fixed to the upper face of the main frame, and
wherein in a case where the building-side extension portion of the support reinforcement part is in contact with the building structure, and the support angle is not in contact with the building structure, at least one portion of the main-frame-side extension portion is able to touch the upper face of the main frame.

### Claim 2 (depends on 1)

The passenger conveyor according to claim 1, wherein in a case where only an end of a lower face of the building-side extension portion of the support reinforcement part is in contact with an end of a floor of the building structure, at least one portion of the main-frame-side extension portion is able to touch the upper face of the main frame.

### Claim 3 (depends on 1)

The passenger conveyor according to claim 1, wherein, while the building structure is shaken, a stress which is to be generated by a support reaction force received by the building-side extension portion from the building structure and which is to be transmitted to the support angle, is smaller than a breaking stress of the support angle.

### Claim 4 (depends on 3)

The passenger conveyor according to claim 3, wherein the stress is smaller than a yield stress of the support angle.

### Claim 5 (depends on 1)

The passenger conveyor according to claim 1, wherein when the support angle is in contact with the building structure, the main-frame-side extension portion of the support reinforcement part is not in contact with the upper face of the main frame.

### Claim 6 (depends on 1)

The passenger conveyor according to claim 1, wherein when the support angle is in contact with the building structure, at least one portion of the main-frame-side extension portion of the support reinforcement part is in contact with the upper face of the main frame.

### Claim 7 (depends on 1)

The passenger conveyor according to claim 1, wherein the main-frame-side extension portion includes a gap adjustment part to adjust a gap between the main-frame-side extension portion and the upper face of the main frame.

### Claim 8 (depends on 1)

The passenger conveyor according to claim 1, wherein an end of a lower face of the main-frame-side extension portion is in a convex rounded shape.

### Claim 9 (depends on 1)

The passenger conveyor according to claim 1, wherein the main-frame-side extension portion includes, at an end of its lower face, a buffer part whose elastic modulus is smaller than that of the main-frame-side extension portion.

### Claim 10 (depends on 1)

The passenger conveyor according to claim 1, wherein the main frame includes, at a portion thereof with which an end of a lower face of the main-frame-side extension portion is to get contact, a buffer part whose elastic modulus is smaller than that of the main-frame-side extension portion.

### Claim 11

A passenger conveyor comprising:
a main frame;
a support angle which is provided at an end in a longitudinal direction of the main frame and which is to be disposed on a building structure;
a support reinforcement part comprising
a connection portion which is fixed to the support angle,
a building-side extension portion which is extended from the connection portion along a floor face of the building structure, and
a main-frame-side extension portion which is extended from the connection portion along an upper face of the main frame,
wherein the main-frame-side extension portion is not fixed to the upper face of the main frame, and
wherein when
a support reaction force received by the building-side extension portion from the building structure is denoted by F [N];
a cross-sectional secondary moment of the support angle on which the support reaction force acts is denoted by I [mm4];
a distance from a base corner of the support angle to an end thereof is denoted by L1 [mm];
a length from the end of the support angle to an end of the building-side extension portion is denoted by L2 [mm];
a length from the base corner of the support angle to an end of the main-frame-side extension portion is denoted by L3 [mm]; and
a longitudinal elastic modulus of the support angle is denoted by E [Pa], a gap between the main-frame-side extension portion and the upper face of the main frame is equal to or less than d2 [mm] which is calculated by a formula of

### Claim 12

A passenger conveyor comprising:
a main frame;
a support angle which is provided at an end in a longitudinal direction of the main frame and which is to be disposed on a building structure;
a support reinforcement part comprising
a connection portion which is fixed to the support angle,
a building-side extension portion which is extended from the connection portion along a floor face of the building structure, and
a main-frame-side extension portion which is extended from the connection portion along an upper face of the main frame,
wherein the main-frame-side extension portion is not fixed to the upper face of the main frame, and
