apparent in the following detailed description, the present
invention will be clearly understood in connection with
the accompanying drawing, in which:
FIG. 1 is a perspective view of a toy partly exploded 45
and provided with a joint coupling device of the present
invention;
FIG. 2 is a longitudinal section of the joints; and
FIG. 3 is a cross-section of the joints.
Referring now to the drawing, the hollow pneumatic
toy body 1 has an air inlet pipe 3 attached thereto and a
small hole 4 is provided on each of the respective joint
faces of the body 1. Hollow toy parts 2 are provided
with joint faces having a small hole 4’, so located as to
be connected with the small hole 4 on the toy body 1. 55
The small holes 4- and 4' are connected at the joint faces
of the toy body 1 and rotatably, as well as air-tightly, ?tted
to each other.

said hollow body,
each of said joint faces of said hollow body and of
said parts having two concentric annular projections
and grooves, respectively, which complement each
other, thereby ?tting tightly and resiliently said parts
to said hollow body,
said projections having opposite sides and each of said
concentric annular projections ?tting into and being
frictionally held by the opposite sides of the com
plementary groove of the other of said joint faces.
