Device and method for properly locating the YardLine numbers of a football field
A template for properly determining the positions for the yardline numbers of an American-style football field includes a generally rectangular frame having an external perimeter and an internal opening defined by an internal perimeter. The shape of the internal opening, and the corresponding shape of the internal perimeter, is such that for each of the yardline numbers, i.e. 5, 4, 3, 2, 1, and 0, the internal perimeter defines a plurality of locations for abutting a corresponding plurality of outer edge portions of the yardline number. With the external perimeter appropriately aligned along one or more lines of the field, the frame can be used to properly locate any one of the six yardline numbers that are needed to properly locate all of the yardline numbers on an American-style football field. This frame reduces the number of templates needed to locate the yardline numbers of a football field, and also simplifies the process of properly locating the yardline numbers.
SHUTTLECOCK LAUNCHING APPARATUS
A shuttlecock loading mechanism with a grabbing mechanism and a pair of ejecting wheels defining a wheel plane. The grabbing mechanism receives a shuttlecock entering the loading mechanism in a vertical position and ejects the shuttlecock from the loading mechanism in an orientation parallel to the wheel plane wherein the pitch of the wheel plane about a wheel horizontal axis is selectively indexed about the wheel's horizontal axis.

Game of skill for propelling and receiving a projectile
The invention concerns a gaming device (1) to throw and catch a ball or a shuttlecock comprising a basket (20) structured around two rigid walls (21, 23) and elastic means (22, 24) for throwing the ball or the shuttlecock with a certain velocity by stretching the gaming device (1), while making it easier to catch the projectile in the structured basket (20) when the gaming device (1) is in resting position.

Shuttlecock and artificial feather thereof
A plurality of artificial feathers connects to a plurality of stems and a base portion to form a shuttlecock. Each of the artificial feathers includes a connecting portion and a resistance portion. The connecting portion connects to one of the stems. The resistance portion connects to the connecting portion, and the resistance portion includes a plurality of low-wind-resistance areas and a high-wind-resistance area. The low-wind-resistance areas are surrounded by the high-wind-resistance area.
