Spacer device for vine support wires, methods for its operation and vine support assemblies comprising the same

A method for operating a spacer device for vine support wires which is adapted to be fixed to a vine post, and made of metal wire and comprising:

• a first ring adapted to encircle the post in a substantially horizontal position and to co-operate with recesses of the post;
• a first and a second arm which extend from the first ring and are respectively equipped with a second and a third ring which are adapted to receive and support vine support wires;
• wherein the first arm has at one end a hook adapted to hook on to the post in the region of an attachment seat of the post in order to couple the first arm directly to the post, and wherein the second arm has at one end a hook adapted to couple the second arm directly or indirectly to the post,
• the method comprising the operations of:
• arranging on a vine post at least one spacer device adapted to support a pair of support wires in an open position, wherein the first and second arms are unhooked from the post;
• causing the spacer device to assume a first closure position, in which at least one of the hook of the first arm and the hook of the second arm is hooked on to an attachment seat of the post placed on the side of the post closest to the arm;
• causing the spacer device to assume a second, tighter closure position, in which at least one of the hook of the first arm and the hook of the second arm is hooked on to an attachment seat of the post placed on the side of the post furthest from the arm.

• a first and a second arm which extend from the first ring and are respectively equipped with a second and a third ring which are adapted to receive and support vine support wires;
• wherein the first arm has at one end a hook portion shaped in such a way as to encircle a section of post, according to the profile of the latter or a line of envelopment of the profile in order to couple the first arm directly to the post, and a plurality of loops adapted to receive and retain in position a hook of the opposite arm, and
• wherein the second arm has at one end a hook adapted to couple the second arm directly to the first arm,
• the method comprising the operations of:
• arranging on a vine post at least one spacer device adapted to support a pair of support wires in an open position, in which the first and second arms are unhooked from the post;
• causing the spacer device to a assume a first closure position, in which the first arm is coupled to the post and the hook of the second arm is hooked on to a first loop of the first arm;
• causing the spacer device to assume a second, tighter closure position, in which the first arm is coupled to the post and the hook of the second arm is hooked on to a second loop of the first arm.
