Toy building blocks with multiple pivoting interconnections

A toy building block construction, comprising;

• a lower body portion having a generally rectangular conformation, an upper body portion integrally formed therewith and having a generally oblate conformation, first and second pairs of detent arms extending from said lower body portion in parallel opposition, a third pair of detent arms extending from said upper body portion in parallel opposition, each of said detent arms including a detent knob formed on an interior surface thereof in confronting relationship with the respective paired detent arm, wherein said first and second pairs of detent arms are arrayed as the limbs of a quadruped animal, and said third pair of detent arms is disposed as the ears of the animal.

A toy building block construction, comprising;

• a block body, a plurality of pairs of detent arms extending from said body, a plurality of pairs of detent recesses formed in said body, each pair of detent recesses disposed to receive one of said pairs of detent arms of a like-formed block in complementary fit fashion, and snap-engaging means for joining said detent arms and said detent recesses in snap-engaging, releasable fashion, said block body including surface conformation means having features of an animal, futher including an upper body portion joined to said block body, said surface conformation means including head and face features on said upper body portion, said plurality of pairs of detent arms include at least two pair of detent arms extending from said block body in parallel opposition and disposed as the limbs of a quadruped animal, and said plurality of pairs of detent arms includes one pair of detent arms extending from said upper body portion and disposed as the ears of an animal.

A toy building block construction, comprising;

• a block body including at least a front surface and a top surface and opposed sides, a plurality of pairs of detent arms extending from said body, including at least one pair of detent arms extending outwardly from said front surface at opposed sides thereof, and one pair of detent arms extending outwardly from said top surface at opposed sides thereof, said front surface and said top surface being non-parallel and non-intersecting, a plurality of pairs of detent recesses formed in said body, each pair of detent recesses disposed to receive one of said pairs of detent arms of a like-formed block in complementary fit fashion, and snap-engaging means for joining said detent arms and said detent recesses in snap-engaging, releasable fashion.

A toy building block construction, comprising;

• a block body, said block body including a main body portion, an upper body portion, and a neck portion joining said upper body portion and said main body portion, said neck portion being relatively narrower than said upper body and main body portions, a plurality of pairs of detent arms extending from said block body, including a first pair of detent arms extending from said main body portion, a second pair of detent arms extending from said upper body portion and disposed non-parallel to said first pair of detent arms, a plurality of pairs of detent recesses formed in said main body portion, each pair of detent recesses disposed to receive one of said pairs of detent arms of a like-formed block in complementary fit fashion, and snap-engaging means for joining said detent arms and said detent recesses in snap-engaging, releasable fashion.
