Document Type and Number:
Japanese Patent JPH0138039
Kind Code:
B2
Abstract:
A device for connecting a sailmast 1 to a sailboard 2 comprises a mast- connecting universal joint 3, which is connected at one end to the mast and is permanently fixed thereto or can be only arbitrarily separated therefrom and is connected at its other end to a supporting member 4, which when the device is in position for use is received at least in part by a recess in the upper surface of the sailboard so as to be positively connected thereto. To provide for an overload coupling, preferably in combination with an easily operable device for shifting the mast in the longitudinal direction of the sailboard, the supporting member is constantly biased by a spring 6 so that the positive connection can be eliminated only in that the spring force is overcome.
