Abstract: A toy brick comprising: a body part with one or more sidewalls extending around the outer periphery of the toy brick which at least partially define an interior of the toy brick and extend from a bottom face to a top portion of the body part, and an elongated rib arranged interiorly on one of the one or more sidewalls. The elongated rib extends at least partially between the bottom face towards the top portion of the body part and the elongated rib is, upon interconnection with another toy brick, configured to be in abutment on coupling means with the other toy brick, the width of the elongated rib, in a central portion in-between the bottom face and the top portion and parallel to the sidewall accommodating the elongated rib, is greater than the width of the elongated rib near its ends parallel to the sidewall accommodating the elongated rib.

Abstract: A toy brick (1), a method of manufacturing a toy brick (1) as well as a mould for the manufacture of a toy brick (1). The toy brick (1) comprising: a body part (3) with one or more sidewalls (5) extending around the outer periphery of the toy brick (1). The one or more sidewalls (5) at least partially define an interior (25) of the toy brick (1) and said sidewalls (5) extend from a bottom face (10) to a top portion (20) of the body part (3), an elongated rib (100) arranged interiorly (25) on one of the one or more sidewalls (5).
