Collapsible canopy frame and locking pin assembly for the same

A locking pin assembly comprising:

• a button movable in a first direction from a first position to a second position;
• a first biasing member for biasing the button to be normally in the first position;
• a locking pin member engaging the button and movable in a second direction, which is substantially perpendicular to the first direction, from a third position to a fourth position when the button is moved from the first position to the second position;
• a second biasing member for biasing the locking pin member to be normally in the third position, and
• a housing for holding the first biasing member, the second biasing member, at least a portion of the button, and at least a portion of the locking pin member,
• wherein the button comprises:
• a pressing member having a first end and a second end, the first end protruding out of the housing through a first opening on the housing when the button is in the first position;
• an engagement member having a first end and a second end, said first end having a tapered tip for engaging the locking pin member;
• and
• a connecting portion disposed between the pressing member and the engagement member, said connecting portion forming a flange between the pressing member and the engagement member,
• wherein a radius of the flange is larger than that of the first opening such that the flange prevents the engagement member from exiting the housing when the first biasing member biases the button towards the first position.

A height adjustment bracket for a collapsible canopy comprising a plurality of telescoping side poles, each having upper and lower telescoping sections, and a plurality of edge scissor assemblies that interconnect the side poles, the height adjustment bracket being for fixing the upper and lower telescoping sections together and comprising:

• a fixing section for engaging a corresponding said upper telescoping section;
• and
• a locking pin assembly attached to the fixing section, comprising:
• a button movable in a first direction from a first position to a second position;
• a first biasing member for biasing the button to be normally in the first position;
• a locking pin member engaging the button and movable in a second direction, which is substantially perpendicular to the first direction, from a third position for fixing corresponding said upper and lower telescoping sections together to a fourth position for disengaging the lower telescoping section from the upper telescoping section when the button is moved from the first position to the second position;
• and
• a second biasing member for biasing the locking pin member to be normally in the third position.

A sliding mounting bracket for a collapsible canopy comprising a plurality of side poles, and a plurality of edge scissor assemblies that interconnect the side poles, the sliding mounting bracket being for coupling the edge scissor assemblies to the side poles and comprising:

• a sliding section for slidably engaging a corresponding said side pole;
• and
• a locking pin assembly attached to the sliding section, comprising:
• a button movable in a first direction from a first position to a second position;
• a first biasing member for biasing the button to be normally in the first position;
• a locking pin member engaging the button and movable in a second direction, which is substantially perpendicular to the first direction, from a third position for fixing the sliding mounting bracket to the side pole to a fourth position for disengaging the sliding mounting bracket from the side pole when the button is moved from the first position to the second position;
• and
• a second biasing member for biasing the locking pin member to be normally in the third position.

A collapsible canopy frame comprising:

• a plurality of telescoping side poles, each telescoping side pole having an upper section and a lower section;
• a height adjustment bracket mounted on each telescoping side pole, comprising:
• a fixing section for engaging the upper section;
• and
• a first locking pin assembly connected to the fixing section, comprising:
• a first button movable in a first direction from a first position to a second position;
• a first biasing member for biasing the button to be normally in the first position;
• a first locking pin member engaging the first button and movable in a second direction, which is substantially perpendicular to the first direction, from a third position for fixing the upper and lower sections together to a fourth position for disengaging the lower section from the upper section when the first button is moved from the first position to the second position;
• and
• a second biasing member for biasing the first locking pin member to be normally in the third position;
• a set of edge scissor assemblies that are pivotably coupled between each of pairs of the side poles, each of said edge scissor assemblies having relatively rotatable ribs;
• a stationary mounting bracket fixedly mounted at top of each telescoping side pole, said stationary mounting bracket being pivotably coupled with upper outer ends of two respective edge scissor assemblies;
• and
• a sliding mounting bracket slidably mounted between the stationary mounting bracket and the height adjustment bracket on each of the telescoping side poles, said sliding mounting bracket being pivotably coupled with lower outer ends of two respective edge scissor assemblies.

A collapsible canopy frame comprising:

• a plurality of side poles;
• a set of edge scissor assemblies that are pivotably coupled between each of pairs of the side poles, each of said edge scissor assemblies having relatively rotatable ribs;
• a stationary mounting bracket fixedly mounted at top of each side pole, said stationary mounting bracket being pivotably coupled with upper outer ends of two respective edge scissor assemblies;
• and
• a sliding mounting bracket slidably mounted below the stationary mounting bracket on each of the side poles, said sliding mounting bracket being pivotably coupled with lower outer ends of two respective edge scissor assemblies, the sliding mounting bracket comprising:
• means for slidably engaging the side pole;
• and
• a locking pin assembly connected to the slidably engaging means, comprising:
• a first button movable in a first direction from a first position to a second position;
• first biasing means for biasing the first button to be normally in the first position;
• a first locking pin member engaging the first button and movable in a second direction, which is substantially perpendicular to the first direction, from a third position for fixing the sliding mounting bracket to the side pole to a fourth position for disengaging the sliding mounting bracket from the side pole when the first button is moved from the first position to the second position;
• and
• second biasing means for biasing the first locking pin member to be normally in the third position.
