along the length of the groove 24 and the connector tongue 28
of a panel in addition to the positive snap-fit locking of the
panel therein by the tensioned engagement of the locking
detents 40 with the lock grooves 24 provided by the stiffly
resilient arm
members. Accordingly, with a panel 10 and a connector member
30 thus engaged, unintended relative pivotal, axial and
separational movement therebetween is virtually eliminated,

the toy includes a floor 2 with perforations 3, four corner
pillars 4, a ceiling 5 with perforations (not shown), and a
plurality of side walls 6 with perforations 8. Heilig teaches
(translation, p. 2) that suitable pieces of furnishings 9 are
provided with pins 10 to be placed in the perforations "on the
bottom." Heilig further teaches (translation, p. 2) that the
perforations 8 in the side walls "accommodate transverse beams
or the like."
