The invention relates to a form-fit locking device (14) for a roller (1), comprising a rotating wheel (2), a fork (3) and a rotary locking engagement (43), the rotating wheel (2) of the roller (1) being rotationally lockable with respect to the geometric axis (y) of the rotating wheel by means of the form-fit locking device (14), and a first spring (58) acting on the rotary locking engagement (43), in this way, the rotary locking meshing piece (43) is moved from the initial position to the meshing position. In order to further improve the design of a form-fitting locking device of the type, it is proposed that the first spring (58) forms a lever arm (68) of the lever part (41), the second spring (59) can be tensioned in order to be moved back to the initial position as the rotary locking engagement part (43) is moved into the engagement position, and the strength of the first spring (58) is greater than that of the second spring (59). Furthermore, the pushrod piece (33) can be formed in a fork shape and has a plurality of pushrod extensions (35, 36) of different lengths, only one pushrod extension (35, 36) being arranged to act on the lever piece (41).

    本发明涉及一种用于滚轮(1)的形状配合锁定装置(14),滚轮具有转动轮(2)、叉件(3)和旋转锁止啮合件(43),其中,滚轮(1)的转动轮(2)能够通过形状配合锁定装置(14)相对于转动轮几何轴线(y)被旋转锁定,此外其中,第一弹簧(58)作用于旋转锁止啮合件(43),以便使旋转锁止啮合件(43)从初始位置移至啮合位置。为了进一步改进地设计所述类型的形状配合锁定装置,在此建议,第一弹簧(58)构成杠杆件(41)的杠杆臂(68),随着旋转锁止啮合件(43)移动到啮合位置中,为了移回到初始位置,第二弹簧(59)能够被张紧,并且第一弹簧(58)的强度大于第二弹簧(59)。此外,推杆件(33)可以构造为叉形并且具有多个不同长度的推杆延伸部(35、36),其中,仅一个推杆延伸部(35、36)布置用于对杠杆件(41)施加作用。
