| 摘要 |
The invention relates to a board-type runner device (1), consisting of at least a top layer (2) with a top surface (4) and a running layer (3) with a running surface (5) lying opposite it and optionally having edging elements (6) extending in the longitudinal direction of the runner device (1), and the top surface (4) of the top layer (2) and/or the running surface (5) of the running layer (3) has at least one recess (13, 14). The at least one recess (13; 14) is provided with a device (21) for increasing slipping and friction resistance at the running surface (5) and/or top surface (4) if necessary, at least in the region of the recess (13; 14).
