  • Patent number: 4941552
    Abstract: A castor has a two-armed integrally formed spring metal brake member which is pivoted on the castor body for selective movement between a braking position, in which a detent portion on one arm brakingly engages teeth on the castor wheel, to prevent wheel rotation, and a detent portion on the other arm engages teeth on a mounting member on which the body swivels, to prevent swivelling, and a release position in which the detent portions are spaced from the teeth.

  • Patent number: 4677706
    Abstract: A single or twin wheel castor has a body (4,14; 90) journalling the wheel (92) or wheels (2) about a horizontal axis, with the body capable of swivelling on a mounting member (16) about a vertical axis spaced from the wheel axis. An operating member (25) is movable axially but non-rotatably by a cam (30) along the vertical axis between a lower position in which the body is held to the operating member and thus to the mounting member in a predetermined angular orientation, the whole being free to turn, an intermediate position in which the wheels are free to turn and the body is free to swivel and an upper position in which a wheel braking force is applied frictionally or mechanically by a brake lever (44, 105), the engagement of the operating member with the brake lever also holding the body in its angular position when the brake was applied.
