ABSTRACT:

The invention relates to a toy building set having interconnectible building elements with coupling studs and coupling cavities which are capable of receiving coupling studs on other toy building elements of the toy building set.
Such toy building sets are known and marketed under the trade marks LEGO or DUPLO and are used by young and older children for the building of imaginative structures where only the imagination sets the limits.
DK 115 237 discloses a toy building set for the building of a ball track. The building set has interconnectible pipe members having a ball-shaped part in the centre and building elements having a ball-cup-shaped opening to receive and hold the ball-shaped part of a pipe member. The pipe member is hereby mounted in a ball joint in the building element.
U.S. Pat. No. 5,451,177 discloses a toy building set having interconnectible building elements and pipe members which per se cannot be built together. Some of the building elements have a semi-cylindrical recess in the top side or in the underside, whereby two building elements together can surround the ends of two pipe members. The ends of the pipe members have a flange which hereby engages a corresponding groove in the semi-cylindrical recesses. Thus, two building elements have to be used in order to assemble two pipe members.
U.S. Pat. No. 4,080,752 discloses a toy building set having pipe members and building blocks which can be assembled in a fluid tight manner by means of O-rings.
The object of the invention is to provide a toy building set having interconnectible building blocks and interconnectible pipe members by means of which even small children, who have no great deftness as yet, can easily build structures having a great play value.
This object is achieved according to the invention in that a building block of the building set has a pipe member firmly integrated in the building block. The pipe member is thus in a fixed position with respect to the building block, which is a help to the child in its play, and with curved pipe members it is possible to assemble longer pipes with curves. The lengths and curves of the pipe members may thus be adapted to the dimensions of the building elements, thereby allowing a flexible and modular system to be created.
