Frame comprising profile connectors with a rotational joint

A frame for a protection device for use with a building opening, comprising

• at least two vertical frame struts (1.1, 1.2) which in each case have at least one outer profile strip (3) and at least one inner profile strip (4) which is inserted in a telescopic manner into the outer profile strip(s) (3) to an insertion depth,
• at least two horizontal frame struts (2.1, 2.2) which in each case have at least one outer profile strip (3) and at least one inner profile strip (4) which is inserted in a telescopic manner into the outer profile strip (s) (3) to an insertion depth, and
• profile connectors (5.1, 5.2, 6.1, 6.2) in each case comprising at least one first connecting arm (7) and one second connecting arm (8), wherein the first connecting arm (7) is at least partially inserted into a profile strip (3, 4) of a vertical frame strut (1.1, 1.2) and the second connecting arm (8) is at least partially inserted into a profile strip (3, 4) of a horizontal frame strut (2.1, 2.2), characterised in that
• each profile connector (5.1, 5.2, 6.1, 6.2) has a rotational joint (11) between the connecting arms (7, 8) having at least one axis of rotation (9, 10), such that in an initial position the vertical frame struts (1.1, 1.2) and the horizontal frame struts (2.1, 2.2) are oriented parallel to one another and that, by pivoting the frame struts (1.1, 1.2, 2.1, 2.2) relative to one another about the axes of rotation (9, 10) of the rotational joints (11) of the profile connectors (5.1, 5.2, 6.1, 6.2) connecting together two respective frame struts, the frame is able to be transferred into an assembly position in which the horizontal frame struts (2.1, 2.2) and the vertical frame struts (1.1, 1.2) are arranged in a frame plane at a right angle to one another.
