    • This invention relates to metal door frames and is concerned with the problem of simplifying the manufacture of such door frames and, therefore, rendering them less costly to produce. According to the invention metal door jambs and wing frames are constructed in the form of special hollow profiles capable of being combined with one another to form boxlike posts so that many different kinds of metal doors can be manufactured using a relatively small number of profiles. In each case a jamb profile and a wing profile has a groove on the sides facing away from each other and, on their adjacent sides, other grooves the width of which increases with the depth of the grooves, which other grooves receive draught excluding sealing strips.
    • 本发明涉及金属门框,并且涉及简化这种门框的制造的问题,因此使得它们的制造成本更低。 根据本发明,金属门边框和翼框架以特殊的中空型材的形式构造,能够彼此组合以形成箱形柱,使得可以使用相对较少数量的型材来制造许多不同种类的金属门。 在每种情况下,侧面轮廓和翼形轮廓在相对于彼此的侧面上具有凹槽,并且在其相邻的侧面上具有宽度随着凹槽的深度而增加的其它凹槽,其它凹槽接收除去密封条 。
