Abstract
Gallows for rings, intended to be used in sport gymnastics, wherein the cross beam is more flexible than conventionally known models. The cross beam is hinged to the uprights of the gallows with a silentblock or rubber piece. The rings of the gallows are connected to the cross beam using rigid rods made of a composite material or other rigid material, with the rigid rods being connected at their tops by a self-locking trunnion provided with a universal joint and fixed to the rings by a short link of textile material. Also, the bottom of the uprights of the gallows are connected by a cable.
