Rebound Tapered Frame Pads
The most impressive frame pads on the market. They are both thicker and tapered. This taper is an exclusive feature which allows for a small bed side thickness where frame pads should move with the springs on impact, yet the maximum thickness where it is most needed, over the metal frame.
Rebound Products has been pioneering the use of both thicker and tapered frame pads for years. We have been instrumental in improving international standards. Before we intervened the minimum required thickness of a frame pad was ZERO! Common pads had a 1 cm thick flap at the hinge and otherwise were about 2.5cm. Now the maximum allowed over the frame is 10 cm, and the minimum 5cm, but a thickness of more than 5cm is rarely made by others.
Our frame pads are the most securely attached to the frame on the market today. Rebound introduced attaching frame pads with Velcro. Imitation is the highest form of flattery.
Other manufacturers resist tapering their frame pads due to additional costs.
The worst situation for athlete safety is a step edge. Imagine landing on your back from height at the end of a trampoline which is above the ground and without end decks. You arrive with your waist on the bed, your shoulders over the frame pads above the frame, and your head over empty space. Not a pretty picture. This is why end decks were invented and are now required at competitions.
Now back to the frame pads along the sides of a trampoline. Let us look at possible depressions at high velocity. At the middle of the bed it could go down close to the floor. At the edges of the bed it can go down over half that far. Yet with a thick un-tapered frame pad over the springs depression might be under 20cm. Then as you go along the frame pad outward, depression will be reduced to only about 2 cm right over the frame.
In a perfect world the depression would go down uniformly from the centre of the bed to above the frame. It cannot, but the closer to that, the better.
There are 3 areas of major concern. First at the bed frame pad interface, the more the frame pad can move down the smaller the step edge. This is the main reason for having a tapered frame pad. Thinner frame padding at the bed edge puts the frame pad top at a level closer to the bed when pressed down, and allows the pads to better follow the springs as they move down under impact. In addition, if an athlete is moving sideways to hit the inside edge of a frame pad, a tapered pad will be thinner at this point and allow more movement before the athlete is stopped. The second area of concern is what happens to an athlete’s ankle if their foot lands just inside the frame? If the frame pad is thin at this point, the spring and the frame pad are quite soft, yet inches away over the frame there is a very hard place. This results in a huge angle inwards and a hazard for ankle injury. If the padding is thick over this area, that risk is reduced. The third area of concern is landing right over the frame where impact absorption distance is dependent only on frame pad thickness and frame pad composition. At this point you also want a thicker frame pad.
So in conclusion, for safety, tapered frame pads are superior.
Now that frame pads are allowed to be up to 10 cm thick at the frame, the composition of the frame pads comes into play. Years of research by gymnastics apparatus manufacturers showed that a 10 cm gymnastics mat (which used to be a standard) was best made with 2 foam layers. The top harder layer was made of a closed cell foam to spread out the impact and give a stable landing surface, the bottom layer was a softer open cell foam which would do most of the energy absorption. Rebound Products did a number of tests which confirmed that such a composition is superior to the one firm layer of foam now required by international rules.
We are hoping to offer a Velcro on under-layer of vinyl covered soft foam which will fit under our frame pads (to become a construction which no longer meets the international standards), so clubs can have something safer during training.
Thickness of our side pads over the metal frame is usually 3”. (4” for ST) The bed side thickness and the end pad thickness is 1.25”. Frame pads also can be custom made to any size.
