<p>A joint device for a leg guard, particularly for a leg guard used by ice- hockey players, comprises a first part that covers the wearer's lower leg, a nd a second part (2) that covers a part of the wearer's thigh above the knee an d that is pivotally connected to the first part (1) via a joint element (4). A cup-shaped third part (3) bridges the gap between the first and the second parts (1, 2) and is pivotally mounted (5) on the second part (2). The joint element (4) includes pins which engage in a slot or groove (11) on the sides of the third part (3), so that the third part (3) will be dogged by the seco nd part (2) when the angle between the first and the second parts is smaller th an a limit angle. The first part (1) includes pins (8) which engage in a second slot (10) in the third part (3). The second slots include a first circular section whose center lies in the first joint element (4) when the guard is a t a more pronounced angle than the limit angle. The second slot (10) has a second section (10b) that extends form the lower end of the first section (10a) in a direction radially away from the second joint elements. When the first and the second parts (1, 2) define an angle that is smaller than the limit angle,the third part (3) and the portions (21, 32) of respective first and second parts overlapped by said third part (3) have generally the same radius of curvature and common centre of curvature in the first joint elemen t (4).</p> |
