Abstract
Abstract A leg guard comprises a first, shell-like section (1) and second shell-like section (2). The first section (1) is connected to the second section (2) by means of two coaxial pivot pins (4) arranged on each side of the leg guard. A cupped part (3) is pivotally connected to the second section (2) by means of two coaxial pivot pins (5) spaced from the first pivot pins. Two coaxial guide pins (8) connected to the first section are each arranged to slide in a groove or slot in the cupped part (3). The arrangement is such that when the leg guard is bent, the second pivot pins (5) cause the cupped part (3) to move in the longitudinal direction of the leg guard, and the guide means formed by the guide pins (8) and the slot or groove guide the pivotal movement of the cupped part around the second pivot pins.

Claim 1
Independent Claim
219 words
Pivot means for a leg guard of the kind comprising a first shell-like section (1) and second shell-like section (2) arranged so as to overlap each other at least partially and pivotally connected together by pivot means; and a cupped part arranged to overlap the first section and the second section and intended to protect the knee of the wearer, characterized in that the first section (1) is pivotally connected to the second section (2) by means of two mutually coaxial first pivot pins (4) arranged on each side of the leg guard; that the cupped part (3) is pivotally connected to the second section (2) by means of two mutually coaxial pivot pins (5) arranged on both sides of the leg guard at a distance from the first pivot pins; and that each of two coaxial guide pins (8) joined to the first section (1) is arranged to slide in hole means (10) in the cupped part (3), the arrangement being such that when the leg guard is bent said second pivot pins (5) cause the cupped part (3) to move in the longitudinal direction of the leg guard and pivoting movement of the cupped part around the second pivot pins (5) is guided by guide means formed by the guide pins (8) and associated hole means (10).
