- an upper part disposed substantially horizontal in a closed position of said guard and connecting said upper end portion of said side part and said upper end portion of said additional side part;
- a frame disposed substantially horizontal in a closed position of said guard, and adjacent said upper part in a closed position of said guard;
- said frame having a first end portion and a second end portion disposed substantially opposite one another, said first end portion being disposed adjacent said side part and said second end portion being disposed adjacent said additional side part;
- said upper part having a first length;
- said frame having a second length;
- said first length and said second length being substantially equal to one another;
- at least one pin configured for pivotally mounting said upper part to said first end portion of said frame;
