Side handle

A rail 18 has a guide surface 24 on which the locking block is guided in a bearing manner between a position locking the bar 10, in which the toothed side 16 engages in the toothed long side 13, and an unlocked position, in which the toothed side 16 is not engaged with the toothed long side 13. A spring 22 pretensions the locking block 15 into the locking position. The guided side 23 and/or the guide surface 24 have a flank 25 that is inclined with respect to the bar axis such that the locking block 15 is forced in the direction of the bar 10 in the event of a movement along the bar axis 12. 轨道18具有引导面24，锁块贴靠着该引导面在将杆条10锁定的位置与解锁的位置之间引导，在所述锁定的位置中带齿侧部16嵌入到带齿纵侧13中，而在所述解锁的位置中带齿侧部16与带齿纵侧13脱开嵌接。弹簧22将锁块15向所述锁定的位置中预紧。被引导的侧部23和/或引导面24具有相对杆条轴线倾斜的型面25，使得锁块15在沿着杆条轴线12运动时被迫靠向杆条10。
