| 摘要 |
The invention relates to a braking and immobilizing brake device for a wheeled chair frame (10) such as a children's pushchair, comprising a drum brake (26) and a brake actuation handle (20) for moving a control element (60) of said drum brake (26). The brake shoe (44) of the drum brake (26) can be moved in a radially outward-pointing first direction proceeding from a central position, until a braking position is reached where a frictional surface (54) frictionally engages with the inner circumferential surface (50) of the drum wall (40), and can be moved in a second direction counter to said first direction, until an immobilizing position is reached in which a brake shoe inner toothing (76) that may be brought into engagement with the outer toothing (80) of a blocking element (42) in order to stop said blocking element (42) causes immobilization. |
