Band flap of a band

Abstract

The invention relates to a band flap (100) of a band for a hinge-articulated connection of a wing to a frame about a hinge axis (S), comprising a longitudinal recess (3), a bearing bushing (4) arranged in the longitudinal recess (D), which is rotatable, by means of an optionally attachable auxiliary rotation aid (12), about a laterally offset axis of rotation (D) that is parallel to the hinge axis(S). Said bearing bushing comprises a bearing bushing recess (5) for accommodating a band pin, having at least one inner thread (35) provided in an end region of the longitudinal recess (3), and a lifting spindle (7, 7') having an outer thread (8) that can be screwed into the inner thread (35). Said lifting spindle has a support side (9) for directly or indirectly supporting the bearing bushing (4) and/or the band pin and is configured as an optionally attachable rotation aid (12). For the purpose of transmitting torques, a key surface (13) is provided on the bearing bushing (4) between the lifting spindle (7, 7') and the bearing bushing (4), and on the lifting spindle (7, 7'), a counter key surface (14) is provided, which can be operatively connected to the key surface (13). According tothe invention, the key surface (13) is arranged on at least one cavity (21a, 21b, 21c, 21d) formed on a circumferential front face surface (6), and the counter key surface (14) is arranged on at least one projection (22a, 22b, 22c, 22d) that is formed so as to correspond with the cavity (21a, 21b, 21c, 21d).

Description

technical field [0001] The invention relates to a hinge leaf for hingedly connecting a leaf to a frame around a hinge axis, said hinge leaf comprising: a longitudinal gap; A pivot axis parallel to the hinge axis, laterally offset, by means of a selectively attachable rotation assist mechanism rotatable support sleeve, said support sleeve comprising a support sleeve recess for receiving a hinge pin; at least provided on said An internal thread in the end region of the longitudinal recess; and a lifting spindle with an external thread that can be screwed into the internal thread, the lifting spindle has a function for indirectly or directly supporting the bearing sleeve and / or In particular, the support side of the hinge pin is facing the first end-side end of the lifting spindle and the lifting spindle is designed as a selectively attachable rotation aid, wherein, in order to connect the lifting spindle with the Torque is transmitted between the bearing sleeves, on which a loc...

Problems solved by technology

[0005] It has been shown that due to the particular shape and the precision required, the cost of producing the locking surfaces and the corresponding locking surfaces in a hexagonal manner is relatively high

In addition, due to the relatively precise fit of the outer hexagon relative to the inner hexagon, the mounting of the corresponding locking surface on the locking surface or the mounting of the lifting spindle used as a rotation aid on the support must be carried out relatively precisely during assembly. put on, but this makes such a work step relatively time-consuming
