SE544791C2 - Multi-purpose constructional elements, arrangements and assembly methods - Google Patents

Abstract

A multi-purpose constructional element (1, 2), an arrangement (100, 200) comprising a plurality of such elements (1, 2) and a method for assembling such an arrangement (100, 200) are provided. The multi-purpose constructional element (1, 2) is configured to be connected to other constructional elements (1, 2) to form an elongated body with a rotational axis A. The constructional element (1, 2) is a form-locking element and comprises a centre portion (11, 21), at least one protrusion (12, 13, 22, 23) extending from the centre portion (11, 21), and at least one recess (14, 24, 27). The at least one protrusion (12, 13, 22, 23) is configured to interact with the at least one recess (14, 24, 27) of another constructional element (1, 2). The constructional element (1, 2) is configured so that, when connected to other constructional elements (1, 2), only the last connected constructional element (1, 2) can be disconnected from the others.
