The longitudinal guide has two long, relatively displaceable rails, guided inside each other. The rails are connected via two rows of roller bodies, and engage on each other pre-tensioned, one rail enclosing the other. Each rail consists of an angled profile, with arm extensions carrying guide flanges for the roller bodies. The two guide flanges (44,46) of the enclosed rail (24) extends inwards from the arm ends (38,36). The enclosing rail (22) has a stop (56), esp. near pref. one guide flange (44), which freely engages over the flange on the inside, and limits the inwards springing of the flange, and an outward springing of the arm (34). |
