The flexible central loop is attached in front of the animal's chest to a standard martingale chest strap and a leather loop around the neck, both adjustable to the horse's size and conformation. Standard reins run through the sliding rein rings, which can change their position on the central loop depending upon which way the rider pulls the reins. The flexible central loop can deform to the pull pressure of the reins, which will mitigate the pressure applied to horse's head, to prevent sudden and forceful pressure that could potentially startle or harm the horse. ## Claims ### Claim 1 A flexible martingale with sliding rein rings for controlling the movement of a horse and used in conjunction with standard horse tack including (1) headgear attached to the horse's head, (2) a breastplate attached to the horse's chest, and (3) reins attached to the headgear and running to the rider, said flexible martingale comprising: a flexible central loop that retains it's shape, said flexible central loop located below the horse's head and attached to the breastplate; two sliding rein rings slidably attached to the flexible central loop and configured to set below the horse's head; wherein said reins run through said sliding rein rings; and wherein when the the reins are pulled the flexible central loop deforms to create a gradual pressure on the horse's head; and wherein when the reins are pulled directly back, due to the location of the flexible central loop and rein rings below the horse's head, the reins will pull downwardly on the headgear and apply downward pressure on the horse's head to induce the horse to lower it's head, and wherein, due to the flexibility of the flexible central loop, the downward pressure on the horse will be gradual and proportional to the natural resistance presented by the horse. ### Claim 2 (depends on 1) The flexible martingale with sliding rein rings of claim 1, wherein said flexible central loop is attached to an adjustable attachment strap, and said adjustable attachment strap attached to the breastplate, which allows the orientation between the rein rings and the horse's head to be adjusted to the rider's requirements. ### Claim 3 (depends on 1) The flexible martingale with sliding rein rings of claim 1, wherein said headgear is a standard bridle with bit placed in the horse's mouth. ### Claim 4 (depends on 1) The flexible martingale with sliding rein rings of claim 1, wherein said headgear is a hackamore with a noseband. ### Claim 5 (depends on 1) The flexible martingale with sliding rein rings of claim 1, wherein the reins comprise a right rein and a left rein, and the two sliding rein rings comprise a right rein ring and a left rein ring, and wherein further the right rein runs through the right rein ring and the left rein runs through the left rein ring. ### Claim 6 (depends on 5) The flexible martingale with sliding rein rings of claim 5, wherein when the reins are pulled to one side it deflects the flexible central loop to that side, and the sliding rein rings slide to that side to create a gradual variable pressure on the headgear and the horse, and allow a rider to control the horse with minimal rein movement. ### Claim 7 (depends on 5) The flexible martingale with sliding rein rings of claim 5, wherein when one rein is pulled it deflects the flexible central loop to that side, and the sliding rein rings slide to that side to create a triangle which lowers the rein rings further below the horse's head, increasing the downward tension on the headgear and urging the horse's head lower in the turn. ### Claim 8 (depends on 1) The flexible martingale with sliding rein rings of claim 1 wherein the flexible central loop can be made of a flexible material to allow deformation of the loop when pressure is applied by the reins on the rein rings. ### Claim 9 A flexible martingale with sliding rein rings for training and controlling the posture of a horse and used in conjunction with standard horse tack including (1) headgear attached to the horse's head, (2) a breastplate attached to the horse's chest, and (3) reins attached to the headgear and running to the rider, said flexible martingale comprising: a flexible central loop, said flexible central loop located below the horse's head and attached to the breastplate; two sliding rein rings slidably attached to the flexible central loop and configured to set below the horse's head; wherein said reins run through said sliding rein rings; and wherein when the reins are held taut there is no slack between a rider's hands and the headgear, and wherein the flexible central loop can deform to allow some head movement by the horse but with continued light pressure on the headgear, and wherein further the flexible central loop can flex and provide additional give, so that light pressure can always be maintained with no slack on the reins, and wherein further the position of the martingale below the horse's head keeps the reins pulling down to keep the horse's head down and neck convex. ### Claim 10 (depends on 9) The flexible martingale with sliding rein rings of claim 9, wherein said headgear is a standard bridle with bit placed in the horse's mouth. ### Claim 11 (depends on 9) The flexible martingale with sliding rein rings of claim 9, wherein said headgear is a hackamore with a noseband. ### Claim 12 (depends on 9) The flexible martingale with sliding rein rings of claim 9, wherein further, when the reins are pulled directly back, due to the location of the flexible central loop and rein rings below the horse's head, the reins will pull downwardly on the headgear and will apply downward pressure on the horse's head to induce the horse to lower it's head, and wherein, due to the flexibility of the flexible central loop, the downward pressure will deflect the flexible central loop to reduce so that the downward pressure on the horse will be gradual. ### Claim 13 (depends on 9) The flexible martingale with sliding rein rings of claim 9, wherein said flexible central loop is attached to an adjustable attachment strap, and said adjustable attachment strap attached to the breastplate, which allows the orientation between the rein rings and the horse's head to be adjusted. ### Claim 14 (depends on 9) The flexible martingale with sliding rein rings of claim 9, wherein the reins comprise a right rein and a left rein, and the two sliding rein rings comprise a right rein ring and a left rein ring, and wherein further the right rein runs through the right rein ring and the left rein runs through the left rein ring. ### Claim 15 (depends on 14) The flexible martingale with sliding rein rings of claim 14, wherein when the right rein is pulled, it pulls the right rein ring and deflects the flexible central loop to create a triangle that lowers the rein rings in relation to the horse's head, further urging the horse to lower it's head during the turn. ### Claim 16 (depends on 14) The flexible martingale with sliding rein rings of claim 14 where the deformable material allows the flexible central loop to deform in shape to left or right as a rein is pulled to that side, and allows constant tension on both the left and right rein regardless of which direction the horse is being turned.
