Abstract

A canopy shelter link point for increased structural integrity particularly when subject to bending forces about the link point. The canopy shelter link point can include an increased overlap distance between two cross members, reduced spacing between adjacent cross members, and/or extension features located about an end of the cross members to reduce the misalignment angle between two cross members. Such features can be provided using spacers, inserts to be inserted into a cross member and/or sleeves to be placed around the cross member. A reduction in the misalignment angle can reduce the amount of bending forces about the link point.

Claims

1. A cross member insert system for a canopy frame having first and second cross members pivotally coupled about a link point axis, the cross member insert system comprising:

a spacer configured to be positioned in a gap between outer surfaces of the first and second cross members and about the link point axis, the spacer comprising a first surface oriented towards the first cross member and a second surface oriented towards the second cross member; and

a cross member insert comprising;

a body portion comprising two long sides and two short sides, the body portion being configured to fit within the first cross member; and

a head portion comprising two long sides, two short sides and an extension extending from at least one of the long sides of the head portion, the head portion being configured to abut an end of the first cross member and the extension extending past the first surface of the spacer, the extension configured to bridge a gap between the first and second cross members, the extension spaced from the link point axis.

2. The system of claim 1, wherein the body portion of the cross member insert extends to the link point axis.

3. The system of claim 2, wherein the body portion comprises a hole about the link point axis for allowing a fastener to pass therethrough.

4. The system of claim 1, wherein a distance between the link point axis and the end of the first cross member is 2 to 5 times a radius of the spacer.

5. The system of claim 1, wherein the extension does not extend to the link point axis.

6. A cross member sleeve system for a canopy frame having first and second cross members pivotally coupled about a link point axis, the cross member sleeve system comprising:

a spacer configured to be positioned between outer surfaces of the first and second cross members and about the link point axis, the spacer comprising a first surface oriented towards the first cross member and a second surface oriented towards the second cross member; and

a cross member sleeve comprising;

a shell portion configured to slide over the outer surface of the first cross member, the shell portion comprising two long sides, two short sides, a first end having an opening sized to receive an end of the first cross member and a second end;

a cap portion comprising a surface extending radially inwardly to abut an end of the first cross member, the cap portion being positioned at the second end of the shell portion; and

a projection extending radially outwardly from at least one of the two long sides of the shell portion, the projection extending toward the second cross member and past the first surface of the spacer, the projection configured to bridge a gap between the first and second cross members, the projection spaced from the link point axis.

7. The system of claim 6, wherein the shell portion of the cross member sleeve extends to the link point axis.

8. The system of claim 7, wherein the shell portion comprises a hole about the link point axis for allowing a fastener to pass therethrough.

9. The system of claim 6, wherein a distance between the link point axis and the end of the first cross member is 2 to 5 times a radius of the spacer.

10. The system of claim 6, wherein the projection does not extend to the link point axis.

11. The cross member sleeve system of claim 6, wherein the projection spans partially across said long side of said shell portion in a direction between the two short sides.

12. The cross member sleeve system of claim 11, wherein:

the first and second cross members form a link point angle;

the first and second cross members have a collapsed position and an expanded position, the collapsed position having a collapsed link point angle that is less than the link point angle in the expanded position; and

wherein the projection is configured to interact with another cross member sleeve to inhibit rotation to a link point angle less than the collapsed link point angle.

13. The cross member sleeve system of claim 6, wherein the cross member sleeve further comprises a receiver portion extending out from an outer surface of the shell portion configured to accept a retaining member.
