DESCRIPTION OP A PREFERRE,D EMBODIMENT OF THE_INYENTION
~ lg. 1 shows a hollo~ lnfl~ted three dlmensional figure 10
comprlsed of a m~ln hollow body 12 and two anlclllary hollow
bodles 14 and 16. The~threc dimenslonal flgure slmulates a
small human belng of doll-like character. Hollow body 12
deflrles a slmulated human torso section 18 and human head
Z~ 8
sectlon 20. Hollow body 14 defines tWQ slmulated human arm
sectlons 22 and 23, whereas hollo~ body 16 deflnes two slmulated
human leg sPctions 2S and 27.
Hollow hody 12 ls formed to lnclude two tubular sleeve walls
30 and 32 extending transversely through the torso sectlon 18.
Hollow body 14 includes a flexlble pipe sectlon 34 extending
through the tube (sleeve) deflned by tubular sleeve wall 32.
Each hollow body 14 or 16 ls formed of two paper-thin
plastlc sheets havlng thelr peripheral edg~ sealed tog~ther to
form a contlnuous edge seam arourld ths resperttve hollow body.
Fig. 3 illustrates the gener~l cross-sectlonal ch~ractar of
hollow body 14, comprising two plastlc sheet~ 37 and 38 having a
¦ co~tlnuous sdge seam connectlo~ 3g ~formed by heat and/or dle
pres~ure).
A co~ventlonal air-lnflatlon tubs 40 (Flg. 1) ls suitably
# l~ affixed to one of the plastlc sh~ets for inflatlng the hollow
i body; a seallng plug ~not shown) 1~ assoclated wlth filler tube
1 40 to seal the pressurlzed alr withln body 1~. Simil~r
I ~lr-flller tube~ are provided for th~ other two hollow bodles 12
~t and 16.
Hollow llmb body 14 may be connected to the torso section
of hollow body 12 before or after body 12 has been lnflated, but
prlor to inflation of body 14. Wlth limb body 1~ in a deflected
condltion, th~ body can be manually passed through the tube
deflned by tubular wall 30, such that flexlble pipe sectlon 3~
is posltloned wlthin tubular wall 30. Hollow body 14 can then
be inflated to caus~ hollow llmbs 22 and 23 to bulge to tha
. --4--
i;
~7~1~8
condl-tion shown ln Fig. 1. The space within plpe sectlon 34 and
llmbs 22 and 23 ls one slngle air chamber; lntroduction of
pressurized air lnto the chamber serves to inflate the plpe
sectlon and both llmbs.
~ s seen in FlgO 1, hollow llmb 22 extends upwardly from axls
13 of tubular plpe sectlon 34. However, the normal unstressed
condltlon of each limb 22 ls downwardly (as per llmb 23). Llmb
22 can be manually swung around axls 13 to assume the upralsed
posltion ef Flg. 1. When limb ~2 ls swung around axl~ 13 th~
flexible pipe sectlon 34 experlences a helical twistlng motionO
The outer surface of pipe sect~on 34 remaln~ ln fric~lon~l
contact wlth the lnner surface of tubular sleeve wall 30.
Therefor~, after the manual force on l~mb 22 is ral0~sed }he
llmb remains in its upralsed position. The limb can be returned
to it~ nonmal lowered posltion, or any lntermedlate posltlon, by
sultable manual manipulation of the llmb. Elther limb 22 or 23
can be swingably manlpulated around pipe axls 13 to assume
varlous ad~usted po~itions.
It should be noted that the space wlthin hollow body 12 ls
pressurized. Therefore tubular sleeve 30 ls pre~surlzed on lts
outer surface, to thus ex~rt a radlal squeezlng actlon on
~lexlble plpe 34. Slmllarly the space wlthln plpe 34 ls
pressurlzed to exert an expanslon force on tha inner surface of
the plpe 34 wall. Thus, the alr pressures wlthln bodle~ 12 and
14 cause plpe 34 to hava a falrly good frlctlonal contact with
the lnner surfac~ of sleeve 30. The len~th of ~leevs 30 ls also
halpful in providlng a fairly large sleeve-plp~3 surf~ce contact
area; irl a typlcal c¢nstructlon sleeve 30 has a length of about
four or five inches. The sleeve ~nd flexlble pipe are ln
4rictional contact along the entire length of the sleeve. All
of these factors cooperate to ensure that limb 22 or 23 ls
capable of being ad~usted and retalned ln any deslred posltlon
of ad~ustment around axis 13.
~ ollow body 16 15 structurally slmilar to hollow body 14.
Body 16 comprlses two plastlc sheets 4~ and 45 havlng æ
continuous edge seam connection 47. Flexlble plpe sectlon 36 of
body 16 is posltionable within the associated sleav~ 32 o~
hollow body 12, such that either llmb 25 or ~7 can be ~wlngably
ad~usted around pi~e axis 48, to assume different ad~usted
po~itlons ext~ndlng forwardly from, or rearwardly from, tor50
18. Durlng such ad~usting actlons flexlble plp~ wall 36 13
sub~ected to a twlsting force, or an untwlstlng force, dependlng
on the directlon of ad~ustment.
Each sleeve 30 or 32 is preferably formed as an integral
part of the wall structure that defines the outllne shapa of
body 12. Figs. ~ through lO illustrate the body 1~ sh~et i~
mat~rlal ln a partlally assembled ~:Eabrlc~ted1 stags. Two
paper thin plastlc sheets 50 and 52 are cut to th~ outline shape
shown ln Flg. 60 The sheet thlcknes~ 1 exagyerated ln the
drawlngs.
Each sheet 50 or 52 has a longltudinal axls 53 and ~ ;
transver~e axls 54. The lndlvldual sheets comprlse two
longitudlnally extending ma~or sheet se~tlons 55 and 58, each
havlng a first inner curved longitudlnal ~dge 56 and ~ second . .
fi
~1~107~88
outer curved longitudinal edge 57. Two integral connector
strips 59 and 60 extend transvers~ly between ma~or sheet
sectlons 55 and 58.
Sheets 50 and 52 are shown superimposed, one of the other,
after which the opposed lnner curved edges 56 are stamp-welded
together, as at ~2. The stamp-weld process ls contlnued along
slde edge areas of connector strips 59 and 60, as at 64. Figs.
7 and 9 are cross-sectlonal views of the two sheets and the
references stamp welds ~ and 64. The face areas of th~ sheets
are shown spaced ~llghtly apart to bett~r illustrato the ~tamp
weld seam ~olnts between tha she~ts.
Wlth sheet~ 50 ~nd 52 stamp-welded at thelr inner ed~es, the
longitudinal sheet-sectlons 55 and 5~ ar~ turned lnsldQ out
(around longltudinal axis 53) to the condltlon shown ln Fig.
10. Thi~ brlng~ the outer longltudlnal edges 57 of the she~t -
sectlon~ together. The confront.lng ed~es 57 are ~tamp-w~lded
tegether, as at 66, to form the hollow balloon body 12 ~Flg.
1). The stamp-weld process is yerformed along the entire length
of the seam defined by curved edge~ 57.
The confrontlng connector strlps 59 form the aforementloned
tubular sleeve 30 tFlg. 1). The confrontlng connector strips 60
~Fig. 6) form the aforementloned tubular sleev~ 32 (Flg. 1).
The two sleeves 30 and 3~ extend transversely through hollow
body 12~ . parallel to transverse axls S4 ~Fig. 6). When
body 12 and tha assoc~ated hollow bodle~ lA and 16 are lnflated
the assembly assum~s the three dlmensional confl~uration shown
ln Fig. 1~ Air pressure forces cau~e the concentric sleeve 30,
8~3
32 and flexlble pipes 34, and 36 to have the clrcular cross
sectlonal shapes shown ln Flg. d.
A prlmary feature of the inventlon is the frictional
interengagement between sleeves 30, 32 and flexlble pi~es 34,
36, whereby the various simulated llmbs 22, 23, 25 and 27 can be
selectively ~wlngably ad~usted tha dlfferent positlons.
The drawlngs show one conflguration and structural
arrangement that can be used ln practlcing the lnventlon. Other
forms and arrangements can be utllized.
