Hockey-goalkeeper pads wearable on body parts (e.g., legs) of a hockey goalkeeper to protect these body parts against impacts from a projectile (i.e., puck or ball) while playing hockey, in which the hockey-goalkeeper pads may be configured to enhance performance, use, and/or other aspects of goalkeeping by the hockey goalkeeper, such as by being more durable (e.g., reducing crushing of padding material), improving rebounding of the projectile (e.g., increasing a rebound speed of the projectile and/or a coefficient of restitution), and/or facilitating their donning and securing by the hockey goalkeeper (e.g., connecting to skates).

The present invention concerns a hit detection equipment, usable by a fighter and an opponent for martial arts such as taekwondo, karate or boxing, comprising a central device, a valid surface, for example a jersey and/or a helmet, and at least one authorized surface, for example a glove and/or a shoe. Said valid surface comprises at least one conductive surface and said authorized surface comprises two conductive structures insulated from each other, intertwined with each other over the entire said authorized surface, and each connected to an electrical terminal, and configured so that a contact of said authorized surface on a conductive surface creates a short circuit between the two conductive structures. The present invention also concerns a method for detecting a hit struck by a fighter on an opponent, for martial arts such as taekwondo, karate or boxing, each equipped with an equipment according to the invention.

The present disclosure provides a joint protection device, comprising a joint protection body that matches a shape of a joint. The joint protection body is a hollow housing having an opened bottom and comprises a front supporting portion and side supporting portions providing supports for the joint. A notch is provided in a portion of the joint protection body, which is close to a joint movement area. The notch divides the joint protection body into a plurality of joint pieces, adjacent joint pieces are connected by two local junctions respectively provided at appropriate positions on two sides of the joint protection body and can rotate with the local junctions as rotation fulcrums. Meanwhile, the present disclosure further provides other joint protection devices similar to the above, where an upper end of a joint protection body is provided with a clearance structure to ensure forward and backward movement of the joint.
