## Abstract

The present invention provides a sidewall system and a collapsible building using the system thereof. The sidewall system has a fixed wall, a sidewall, and a single-side eave system that has an eave panel that can be unfolded and folded along with the movement of the sidewall automatically. A collapsible building with two sidewall systems and a sliding, retractable roof is also provided. The collapsible building can create an enclosed space easily and quickly.

## Claims

### Claim 1

A sidewall system, comprising:
a fixed wall;
a sidewall pivoted to the fixed wall, the sidewall rotates around the fixed wall about a pivoting axis; and
a single-side eave system attached to the sidewall comprises:
a gear rod, the gear rod is mounted and fixed to the fixed wall, the gear rod is coaxial with pivoting axis of the sidewall;
an eave panel hinged to the sidewall, the eave panel rotates around hinge axis correspondingly;
a gear, teeth of the gear and the gear rod engage with each other, the gear is attached to and coaxial with a drive shaft; wherein the drive shaft is rotatably mounted on the sidewall; and
at least one support rod, one end of the support rod is slidably pivoted on the eave panel and another end is securely coupled to the drive shaft, the drive shaft rotates the support rod.

### Claim 2 (depends on 1)

The sidewall system of claim 1, wherein the amount of the support rods is 2 or more.

### Claim 3 (depends on 1)

The sidewall system of claim 1, wherein the single-side eave system comprises:
an outer cylindrical gear rod shell, the outer cylindrical gear rod shell is arranged on the fixed wall along the gear rod;
an inner cylindrical gear rod shell, the inner cylindrical gear rod shell is arranged on the sidewall along the gear rod; and
wherein, the inner cylindrical gear rod shell is shorter than the outer cylindrical gear rod shell in radius; the outer cylindrical gear rod shell, and the inner cylindrical gear rod shell jointly cover the gear rod.

### Claim 4 (depends on 1)

The sidewall system of claim 1, wherein the single-side eave system includes a ring gear shell; and the ring gear shell is mounted on the fixed wall, space inside the ring gear shell accommodates the gear when the gear is close to the fixed wall.

### Claim 5 (depends on 1)

The sidewall system of claim 1, wherein the single-side eave system includes at least one sleeve for the drive shaft, the sleeve is fixed to the sidewall, the sleeve is coaxial with the drive shaft, and the sleeve defines a rotation space for the drive shaft therein.

### Claim 6 (depends on 5)

The sidewall system of claim 5, wherein the single-side eave system comprises 2 or more sleeves, the sleeves are fixed to the sidewall at equally spaced distances along drive shaft axis.

### Claim 7

A collapsible building comprising:
a first fixed wall;
a first sidewall pivoted to the first fixed wall, the first sidewall rotates around the first fixed wall about a first pivoting axis;
a first single-side eave system comprises a first eave panel hinged to the first sidewall, the first eave panel rotates around a first hinge axis correspondingly;
a second fixed wall;
a second sidewall pivoted to the second fixed wall, the second sidewall rotates around the second fixed wall about a second pivoting axis;
a second single-side eave system comprises a second eave panel hinged to the second sidewall, the second eave panel rotates about a second hinge axis correspondingly;
the first fixed wall, the first sidewall, and the first single-side eave system form a first sidewall system in open state, at which state angle between the first sidewall and the first fixed wall is 180°;
the second fixed wall, the second sidewall, and the second single-side eave system form a second sidewall system in open state, at which state angle between the second sidewall and the second fixed wall is 180°;
the first sidewall system and the second sidewall system in the open state are facing each other;
a retractable roof includes a plurality of roof sections that each span width of the first sidewall system and the second sidewall system facing each other; some of the roof sections are fixed, and some of the roof sections are movable roof sections; and
wherein some movable sections are slidably mounted on top surface of the first and second sidewall, the movable roof sections being moveable in a direction along length of the wall set to convert the retractable roof between an open configuration and a closed configuration, some of the roof sections overlapping one another when the retractable roof is in the open configuration, region between the first sidewall system and the second sidewall system is covered by the roof sections when the retractable roof is in the closed configuration.

### Claim 8 (depends on 7)

The collapsible building of claim 7, wherein the first fixed wall and the second fixed wall are connected by a base plate as one piece.

### Claim 9 (depends on 7)

The collapsible building of claim 7, wherein the first sidewall includes first roof tracks mounted on top, the movable roof sections move along the first roof tracks to convert the retractable roof between the open configuration and the closed configuration; and the second sidewall includes second roof tracks respectively.

### Claim 10 (depends on 7)

The collapsible building of claim 7, further includes:
a first exterior wall firmly attached to the first fixed wall and the second fixed wall respectively; and,
a second exterior wall detachably connected to the first sidewall and the second sidewall respectively.
