Abstract
The invention provides an improved brush pad for curling brooms of the push broom type. The pad includes a base plate for connection to the broom, a cushioning pad and a fabric cover, all in waterproof material to avoid the development of moisture in the brush pad.
Description
TITLE OF THE INVENTION
CURLING BRUSH PAD
FIELD OF THE INVENTION
The present invention relates to a brush head pad for curling push brooms. In particular, but not exclusively the invention is for intended for replacement heads for existing push broom models. The invention can also be applied to fixed brush head installations, and future brush head developments.
BACKGROUND OF THE INVENTION
A variety of replacement brush pads are already commercially available for curling push brooms. All of them with a construction consisting of a porous foam pad and a fabric surface to sweep the ice in the game of curling. The objective of sweeping the ice is to polish the surface so the curling rock can travel faster and in a straighter line of direction on the ice.
Typical examples of current brush heads with replaceable brush pads are represented by Canadian patents:
2297466 Curling Broom Ferland, A 2006 2173629 Curling Broom Asham, A. 1997 1275765 Curling Broom Head Lindman, D. Busse, D. 1990 Huxham, W
2279025 Curling Broom Device Kuzych,L 2009 The problem with the current products is that they all will absorb humidity, resulting in a moist surface that will diminish the effect of the sweeping.
By private studies and product development, the invention has been developed over a 2 years period, holding on to the theory that a dry, slightly structured surface will provide the most advantageous method of polishing the ice surface and remove any frost or loose particles off the ice surface.

OBJECTS OF THE INVENTION
An object of the invention is to provide a brush pad that will not get moist or wet during the game of curling, allowing the athletes to use the same brush pad throughout a whole game and maintain the effect of the sweeping without having to increase the level of energy in the sweeping motion.
Another object of the invention is to provide a brush pad that will help keeping the ice pebble (Structure of the curling ice surface) intact and not breaking it down by sweeping with a moist surface.
Yet another object of the invention is to provide a brush pad that is slightly structured allowing a more effective removal of frost and debris from the running path of the curling rock.

SUMMARY OF THE INVENTION
More specifically, in accordance with the present invention, there is provided a brush pad comprising a base plate made of plastic or wood, with a vapour barrier, a structured cushioning layer and a fabric cover.
The cushioning layer is made of two bonded layers of heavy gauge polyethylene bubbles, coated with a strengthening film (total thickness 5/16"), or two layers of ribbed polyethylene film bonded in a cross patterned manner. (total thickness 3/8") The construction over a wood base plate requires a polyethylene film to be bonded to 1o the wood material as a vapour barrier before applying the cushioning layer.
The use of polyethylene and air pockets in the cushioning layer prevents any accumulation of moist in the brush pad, and at the same time creates a slightly structured surface for better efficiency in removal of frost and debris.
The cushioning layer is bonded to the base plate.
The ice engaging brushing surface is an acrylic coated 100% woven polyester fabric in 200 to 800 Denier count, providing a waterproof fabric surface with high polishing capacity. Although waterproof, the fabric is breathable to prevent condensation inside the fabric.
The fabric layer which functions as the brushing surface, engaging the ice surface is attached to the base plate by being stapled to the back side of the base plate.

DETAILED DESCRIPTION OF THE INVENTION
The brush pad comprises a base plate made to fit a standard brush head for push brooms, which configuration and shape may vary, but is generally attached to the sweeping body of a curling broom through threaded holes in the base plate (2.) as shown in all figures.
The base plate might be of a synthetic (plastic) material (1.) or made of a wooden material. If a wooden material is used (6.) as shown in figure 3, a vapour barrier of polyethylene film (7.) will be bonded to the wooden surface on the side facing the 1o cushioning layer.
The Cushioning layer can be made of two bonded layers of heavy gauge polyethylene bubbles, coated with a strengthening film (total thickness 5/16") (3.), or two layers of ribbed polyethylene film bonded in a cross patterned manner (total thickness 3/8") (8.,9.) The cushioning layer will be bonded to the base plate on the ice surface side and up all edges of the base plate to avoid any hard or sharp edges of the brush pad touching the ice. (Fig. 2 and Fig. 4) The ice engaging brushing surface is an acrylic coated 100% woven polyester fabric in 200 to 800 Denier count to ensure a waterproof contact surface to the ice, yet with high polishing capacity. (4.) The fabric is stretched over the cushioning layer and attached to the base plate by the way of staples. (5.) The total construction of the brush pad is made for the purpose of making brushing or sweeping in the sport of curling easier for the athlete by preventing the ice engaging surface of the pad from getting wet, yet being effective in polishing the ice surface and removing debris such as ice particles, hairs and other material inadvertently dropped on the ice surface . This is achieved by using a construction and choice of materials as described and illustrated.

This is achieved by using a construction and choice of materials as described and illustrated.
In operation, the ice engaging surface is scrubbed over the ice surface in a sweeping manner by the athlete. The fabric of the ice engaging surface will polish the ice surface without breaking down its structure as long as the surface of the brush pad is dry. The structure of the cushioning layer will remove any frost or debris effectively, s thanks to the bubbles or cross mounted ribbed pattern in the cushioning layer. The fact that the cushioning layer contains only polyethylene and air prevents the brush pad from heating up, and the fact that the fabric is waterproof but breathable ensures that there is no condensation build-up inside the brush pad. The acrylic coating of the fabric used, ensures that the contact with the ice surface has much less friction io than traditional brush pad covering. This will in turn benefit the athlete as less energy is needed to polish and clean the ice surface.
