DEVICE FOR TYING-UP AN ANIMAL

摘要

There is described a device for tethering an animal which includes a suspension element having a base to be hung from a fixed structure, two arms having upper ends fixed to the base and lower ends, the base and the arms definine a plane, a bottom piece for connection to the fixed structure, first pins supported by the arms adjacent to the lower ends and at right angle to the plane and two legs forming together with the bottom piece a yoke. Each of the legs comprises a top part, a lower part, a first hinge connecting the top part to the lower part and a second hinge connecting the lower part to the bottom piece. Each of the top parts is hinged about one of the first pins and has a portion projecting above the first pin and a portion projecting under the first pin, the first hinges and the second hinges allowing movement of the lower parts both in the plane and outside the plane defined by the base and the arms. Each of the legs also includes second pins supported by the arms parallel to the plane. The present tethering device further comprises a control member having a base and two arms. The arms of the control member have ends fixed to the base of the control member and ends hinging about the second pins, the control member thus hinging about the second pins with respect to the suspension element between a first position in which the base of the control member is lower than the second pins and a second position in which the base of the control member is higher than the second pins. The control member acts on the portions of the top parts projecting above the first pins and retaining in its first position the portions projecting above the first pins in a converging position and retaining in its second position the portions projecting above the first pins in a parallel position. The control member further includes a spring having two ends, one of the ends being connected to the control member and the other of the ends being connected to the suspension element. The spring passes through a dead position when the control member moves from its first position to its second position. On one side of the dead position, the spring pulls the control member to the first position and on the other side of the dead position, pulls the control member to the second position.
