Abstract
Disclosed herein is a device for jointing poles of a tent. The device has a housing and a rotor body. In this case, the housing consists of a first pole insert hole for receiving a pole, a seat slit in which the rotor body is seated, and a locking recess formed on each sidewall of the seat slit. The rotor body consists of a longitudinal hinge hole receiving a hinge pin therein such that the rotor body seated in the seat slit of the housing is rotatably jointed to the housing. A locking lug is inserted into an associated locking recess of the housing to limit rotation of the rotor body. A second pole insert hole receives another pole. Furthermore, the device includes a unit for automatically releasing the rotor body from the housing. The automatic releasing unit consists of an elastic member mounted by a locking member to an end wall provided at the inside end of the seat slit. The elastic member allows the locking lugs of the rotor body to be automatically removed from the locking recesses of the housing when collapsing the tent.
