Description
BACKGROUND OF THE INVENTION
In the prior art devices such as the patent to Kratt et al., U.S.
Pat. No. 2,700,245, there is disclosed an animated bubble toy in
the form of a pipe or horn carrying at its forward end an open
receptacle for the bubble forming solution. A film forming member
having a plurality of openings therein is moved out of the solution
through the open receptacle when air is blown into the other end of
the horn, and a bubble is formed and ejected through each opening
in the member. The latter returns to the solution by gravity when
the air input is discontinued. The above device must be carefully
hand held when in use to avoid spillage of the solution from the
open receptacle.
SUMMARY OF THE INVENTION
The animated bubble forming device of this invention is mounted on
a cap which is worn on the head and is provided with a flexible
hose reaching to the mouth and having a mouthpiece so that bubbles
may be formed by blowing into the mouthpiece while the hands are
free. As in the above mentioned prior art device, a pair of
telescoping tubular members are provided, one of which may be
integrally formed with and extends from the bottom of the
receptacle and being open at both ends. Air blown into the lower
end will raise the other tubular member which is provided with a
cover. The other tubular member carries the film forming device
which moves into and out of the film forming solution. Another
distinguishing feature over the prior art is that the solution
container or receptacle is of truncated conical shape with the end
of smaller diameter forming the base. The container is provided
with a cover having an opening spaced from the rim thereof and of a
size and shape to just allow passage of the film forming member,
which together with the shape of the container minimizes spillage
of the solution. Further, the telescoping members are provided with
longitudinal spacing means between them to maintain them in
concentric relation with a minimum of frictional surface contact.
The upper end of the movable tubular member is provided with a
freely rotatable propeller which is rotated by air passing through
small openings in the cover of the tubular member when air is blown
into the flexible conduit. The above and other improvements over
the prior art will be pointed out in detail with specific reference
to the drawings.
OBJECTS OF THE INVENTION
It is therefore an object of the invention to provide an animated
bubble forming toy which can be carried on the head.
It is another object of the invention to provide the above toy with
a container for the bubble forming solution which is not easily
spillable.
It is a further object of the invention to provide the above toy
with movable telescoping tubular members which are maintained
concentric and have a minimum of surface contact to avoid
sticking.
It is still a further object of the invention to provide a more
animated toy by the addition of a freely movable blade or propeller
which is rotated by air blown into the same inlet as used for
forming the bubble.
These and other objects will become apparent as the description of
the invention proceeds by reference to the drawings in which:
FIG. 1 is an isometric view of the device worn on a user's head
with the film forming device producing bubbles while air is blown
in by the user.

DESCRIPTION OF THE INVENTION
With particular attention to the drawing, a base 1 for the bubble
forming device is in the form of a hat which may be fastened to a
child's head by means of a chin strap 2. The hat may be of any
preferred material including a rigid plastic. Attached to the hat
is the receptacle or container 4 for the bubble forming solution.
As shown, the container is of frusto-conical shape with the smaller
diameter end forming the base of the container. Rising centrally
upward from the base 5 of the container and formed integral
therewith, are a pair of spaced outer and inner concentric tubular
members 6 and 8. The larger diameter end of the container is
provided with a top wall 10 extending between rim of the container
and the outer wall of the outer tubular member 6. The top wall may
of course, be formed integrally with the container and member 6.
The latter terminates at or just above the top wall 10 of the
liquid resevoir 4, while the fixed tubular member 8 extends further
upwardly and is provided with an opening 13 through its peripheral
wall.
In telescoping relation with the tubular members 6 and 8 and
extending between them with a sliding fit, is a movable
intermediate cylinder or tubular member 12 provided with a cover 14
which may be of any shape, preferrably domed to have the appearance
of a cap and provided with a projecting piece 14 simulating the
visor. The intermediate tubular member is provided with a key 17
slidable in a longitudinally extending keyway 18 in the inner
tubular member 8. The keyway terminates intermediate the ends of
member 8 to prevent the member 12 from escaping when forced
upwardly, as later explained. The outer wall of the inner tubular
member is is provided with longitudinally extending,
circumferentially spaced ribs bearing against the inner wall of the
movable member 12. It was found that splash from bursting bubbles
could wet the surfaces between the tubular members 6 and 12 and the
resulting viscous drag, between them would be so great that the
movable tubular member 12 would stick in its upper position and not
slide down to its lower position. The ribs serve to maintain the
concentricity of the cylindrical or tubular members with a minimum
of surface contact between them to minimize viscous resistance.
Obviously, the ribs may be formed on the movable member instead. In
the same way, ribs may be provided between the inner and outer
walls of fixed tubular member 6 and movable tubular member 12
respectively, if so desired.
Fixed to the outer wall of the movable member 12, centrally of and
below the visor 16, is the film forming device 20 similar to that
disclosed in the aforementioned patent. The device is of flat
material having an attaching portion 22 which is fixed to the outer
wall of member 12 and a dipring portion 24 offset by an amount
equal to the thickness of member 6 and extending parallel to the
outer wall. The dip-ring is provided with a bubble forming opening
26 centrally below the visor. The device 20 is curved to conform to
the curvature of the tubular member 6 which it overlies when in
lowered position. The top wall 10 of the container, is provided
with a slot 28 through which the offset film-forming device 24 can
move into or out of the container. The slot 28 is spaced radially
inward of the outer periphery of the container and close to the
tubular member 6 so that spillage of the contents will not take
place even when tipped as much as 45 degrees in any direction, as
shown in FIG. 6. The peripheral wall of the movable tubular member
12 is provided with an opening 30 therethrough which is in
alinement with opening 26 in the film-forming device 20, the axes
of openings 13, 26 and 30 being in a common vertical plane. The
bottom wall 5 of the container has an inlet opening 32 registering
with the outlet of a rigid conduit 34, to the inlet of which a
flexible conduit 36 is attached. The flexible conduit is of a
length to reach the mouth of the wearer of the bubble making toy
and may be provided with a mouthpiece, if so desired. The domed cap
14 is provided centrally thereof with an elongated bearing 38
extending inwardly from the outer periphery of the cap. A propeller
blade 40 is fixed on a shaft 42 wich is journaled in the bearing 38
for free rotation therein, the shaft extending through the bearing
at its inner end and being retained therein by any desired manner
such as by a washer 44 clamped on the inner end of the shaft. The
domed cap is provided with one or more openings 44 through its
upper wall to form a passageway for a stream of air from within the
dome to impinge upon the blade to cause rotation thereof.
Air exiting from the opening 44 may also be utilized to create
whistles, sirens or other sounds, as is known in the art. As can be
seen from the drawing, the film forming member 20 may be shaped to
have face-like features and the dip-ring 24 may have the appearance
of a mouth.
By blowing air into the flexible conduit, the pressure created
within the tubular member 12 will force it upwardly, raising the
dip-ring out of the bubble forming solution with a film of such
solution adhering thereto. When the tubular member 12 is raised to
such a height that the key 17 is at the upper end of slot 18,
openings 26 and 30 in the dip-ring and movable member 12
respectively, are in alinement with opening 13 in fixed member 8,
the air passes through such openings to direct air from within
against bubble forming opening 26. The openings 44 in the cap 14
are of such small size that the slow leakage of air therethrough
does not prevent the lifting of the movable member 12 and forming
and ejecting of the bubbles from opening 26. When the air pressure
is lowered or discontinued, the movable tubular member will descend
to lower the film forming member into the solution.
The toy thus described is attractive, is animated and performs the
function of blowing bubbles while leaving the hands free for other
activities and is practically spillproof, permitting the wearer to
move about in unrestricted fashion. The receptacle 14 may be formed
integral with the cap 1 or secured directly thereto making
provision for accommodating the conduit 34. The receptacle may also
be formed with or have a clamp attached thereto for mounting on the
handle bars of a bicycle, or to a rod or wand for holding it in the
hand.
Having thus described the preferred form of the invention with the
particularity required by the statutes, it should be understood
that obvious changes by those skilled in the art may be made
without departing from the spirit and scope of this invention.
