• a plurality of legs, each having an end fixedly connected with the first or second lateral bar;
• a plurality of oblique bars, each having a first end and a second end, wherein the first end of each respective oblique bar in the plurality of oblique bars is pivotally connected with a corresponding leg in the plurality of legs;
• and
• a plurality of sliders, each comprising:
• a sleeve slidably coupled with the first or second longitudinal bar, wherein a first hole and a pillar are formed at a first side wall of the sleeve;
• a pivoting portion integrally formed with the first side wall of the sleeve, and pivotally coupled with the second end of an oblique bar in the plurality of oblique bars, wherein the pivoting portion is protruded from the first side wall of the sleeve and has a pivoting axis substantially perpendicular to the first side wall of the sleeve;
• and
• a controller disposed side by side with the pivoting portion along a longitudinal direction of the sleeve, and configured to control movement of the sleeve along the first or second longitudinal bar, wherein the controller comprises:
• a casing integrally formed or coupled with the first side wall of the sleeve and surrounding the first hole and the pillar formed at the first side wall of the sleeve;
• a lever comprising a first end portion aligned with the first hole formed at the first side wall of the sleeve, a second end portion aligned with the pillar formed at the first side wall of the sleeve, and a middle portion between the first and second portions and pivotally connected with the casing;
• a pin integrally formed or coupled with the first end portion of the lever, wherein the pin has a free end toward the first hole formed at the first side wall of the sleeve;
• and
• an elastic member engaged with the pillar formed at the first side wall of the sleeve, the elastic member having a first end abutting the first side wall of the sleeve and a second end abutting the second portion of the lever, wherein when the first hole formed at the first side wall of the sleeve aligns with a hole of the first or second longitudinal bar, the elastic member pushes the pin into the first hole formed at the first side wall of the sleeve and the hole of the first or second longitudinal bar, thereby restricting movement of the sleeve with respect to the first or second longitudinal bar.

A frame comprising:

• a first longitudinal bar disposed at a first side of the frame;
• a second longitudinal bar disposed at a second side of the frame and substantially parallel to the first longitudinal bar;
• a first lateral bar disposed at a third side of the frame and having a first end pivotally connected with the first longitudinal bar and a second end pivotally connected with the second longitudinal bar;
• a second lateral bar disposed at a fourth side of the frame and having a first end pivotally connected with the first longitudinal bar and a second end pivotally connected with the second longitudinal bar;
• a plurality of legs, each having an end fixedly connected with the first or second lateral bar;
• a plurality of oblique bars, each having a first end and a second end, wherein the first end of each respective oblique bar in the plurality of oblique bars is pivotally connected with a corresponding leg in the plurality of legs;
• a plurality of sliders, each comprising:
• a sleeve slidably coupled with the first or second longitudinal bar, wherein a first hole and a pillar are formed at a first side wall of the sleeve;
• a pivoting portion integrally formed or coupled with the first side wall of the sleeve, and pivotally coupled with the second end of an oblique bar in the plurality of oblique bars;
• and
• a controller disposed side by side with the pivoting portion along a longitudinal direction of the sleeve, and configured to control movement of the sleeve along the first or second longitudinal bar, wherein the controller comprises:
• a casing integrally formed or coupled with the first side wall of the sleeve and surrounding the first hole and the pillar formed at the first side wall of the sleeve;
• a lever comprising a first end portion aligned with the first hole formed at the first side wall of the sleeve, a second end portion aligned with the pillar formed at the first side wall of the sleeve, and a middle portion between the first and second portions and pivotally connected with the casing;
• a pin integrally formed or coupled with the first end portion of the lever, wherein the pin has a free end toward the first hole formed at the first side wall of the sleeve;
• and
• an elastic member engaged with the pillar formed at the first side wall of the sleeve, the elastic member having a first end abutting the first side wall of the sleeve and a second end abutting the second portion of the lever, wherein when the first hole formed at the first side wall of the sleeve aligns with a hole of the first or second longitudinal bar, the elastic member pushes the pin into the first hole formed at the first side wall of the sleeve and the hole of the first or second longitudinal bar, thereby restricting movement of the sleeve with respect to the first or second longitudinal bar;
• and
• a plurality of stoppers, each fixedly coupled with a longitudinal bar in the first the second longitudinal bars at a position between a lateral bar in the first and second lateral bars and a corresponding slider in the plurality of sliders, thereby preventing the corresponding slider from moving further toward the lateral bar and thus preventing the plurality of legs from rotating beyond its unfolded state, wherein each respective stopper in the plurality of stoppers comprises an protrusion;
• and
