Tent frame has anti-collapse device with elastic cords tensioned between hooked sections of setting devices and positioning members of rotary joint to ensure correct position in event of wind

摘要

The tent frame has an anti-collapse device with setting devices (6) which can each be fitted onto a specific point and each have a hooked section (61). Each of the articulated joints (7) has an upper cone in which an end of a support rod (3) is fitted and which has at the lower section a rotary joint fork with slot to take a protruding positioning member which is associated with a torsion spring. A lower cone has at the top an end section rotatably mounted in the fork. Elastic cords (8) are provided of which each is tensioned between the hooked section of the setting device and the positioning member of the joint so that when the elastic cords are pulled the positioning member rotates clockwise to ensure the correct position.
