~0 Best Mode For Carrying Out the invention Referring to Fig.l of the drawings, the tire puncture repair device of the present invention comprises a~shank member 20 attached on a rear end to a handle 10 adapted for torque application, a generally conical penetrater 30 attachable to the fore end of the shank member, and a c,ombined bolt/cover assembly 40.
The conical penetrater 30 has a helical cutting thread 31 formed Ih~ G.Uu.. ~ for boring through a tire puncture. Al the base of the penetrater is a cylindrical plug 32 . , .
~1 8844 having a pair of axially aligned radial protrusions 321 thereon. An eyelet lug 33 having a ~GI~fl~ UUI~l aperture is fixed to the circular base of the plug.
The repair device is used in conjunction with an elongate obturater strip 50 of a resilient material such as natural rubber of suitable synthetic. As shown in Fig.3, the 5 obturater strip has a generally ~c~ ,ul~l section taken along a near diametrical chord, with one end 51 thereof having a tapering i During; ~ . the obturater strip is inserted tapered end first through the aperture of the eyelet lug 33 to a centrai position thereon and folded lengthwise about the eyelet. The folded member 50 which now assumes a nearly circular section is theninserted into a bore 22a in the fore end of shank member 20 which preferably has been pre-lubricated.
The fore end of the shank member is of cylindrical form for optimal insertion through a tire wall, and has an opening 23 in with the bore therein defined by an elongate cut out portion having the form of a cylindrical arc segment. The folded strip 30 extends through the area of the opening after insertion through the bore of the shank member wherein the protrusions 321 slide into cooperating notches 21 formed around the periphery of the terminal end of the shank member. The penetrater is thus rotatingly coupled with the shank member so as to tum therewith.
Between handle 10 and the cylindrical fore end of shank 20 is an adjoining medial portion having opposed laterally extending anchor plates 24 to which the ends of the folded obturater strip can be releasable secured. Between the anchor plates is a block 28 having a central recessed channel 27 axially aligned with the shank member. Narrow incised securing slots 25 extend inward from the rear periphery of each anchor plate.
After insertion through the bore and opening of the shank member the ends of an obturater strip 50 are manually extended under tension through respective guide ducts 26 defined between the peripheral walls of the anchor plates and the sides of block 28, and wedged in place within respective slots 25, as shown in Fig.4.
The cover/bolt assembly 40 compnses a bolt member 41 and an attached cover plate45. The elongate bolt member which is of ~ l ' length has a dorsal protruding lug 42 proximate a rear end thereof The lug 42 extends through an axially aligned slot 46 of ~1 c;d~,L~I IlI;..~,;i length on the cover plate. A top piece 48 is fixed over the lug to secure the bolt member to the cover, as shown in Fig.5. A pair of lateral slats 43 at the base of the iug are in abutment against the bottom of the cover plate. The coverlbolt assembly is positioned on the medial portion of the shank member by first placing a rear end portion of cover plate 42 in a recess 281 at the rear of block 28, and cllhcP~lllPntly sliding the plate forward until the forward end of the cover plate is in abutment with the rim of opening 2~ .
~ 1 ~8~4 WO 95130535 F~ w~,.,.'~ 3?
An arcuate slot 44 protruding ~ y from the forward end of plate 45 y inserts into bore 22a and is in abutment with the sL~..Uu.~ wall.
Referring also to Fig.2, plate 45 covers opening 23 and any obturater strip therein, and is ,,. ",r. " ~ y shaped such that the portion of shank member 20 forward plates 24 has a 5 cyiindricai form, facilitating insertion through a tire. Laterai notches 47 on either side of the cover plate are in registry with ducts 26, providing openings of suffcient height for the passage of the end of portions of an obturater trip. The rear of bolt member 41 is slidingly positioned within an axially aiigned channel 27 in block 28 with a ~
recess 28a ~ slats 43, whjle the front portion thereof is positioned between lO folded haives of any obturater strip disposed in the shank member. The bolt member extends through bore 22a upon a forward ~ ",. ..l to a stop position defined by slot 46 on the cover plate. Initially, bolt member 41 is at a rear stop position within channel 27, whereat the coverlbolt assembly is releasably secured to the shank member by rotating a hingedly connected hasp 29 disposed to the rear of recess 281 so as to engage a catch 15 recess 49 on the top piece.
In operation, an obturater strip 50 is inserted through the eyelet 33 of the penetrater member, folded in haif and inserted into the bore in shank member 20, and secured to anchor plates 24 as ~"cd~ ,i. After the cover/bolt member assembly is secured inplace, the penetrater member is directed into a puncture on a tire and rotated ~h~,. CLI,I uu~;l.
20 by turning the handle member I û. Preferably, the punctures should have been widened by augering with a suitable hand tool such as a square section awl, and lubricated so as to facilitate entry of the penetrater member and the fore end portion of the shank member .
Fig.6 shows the tire puncture repair device after the penetrater member has traversed the thickness of the tire. After traversal of the tire wall, the ends of the obturater strip 50 are 25 released from the securing slots 25, and the hasp 29 disengaged from the top piece. The top piece and bolt member are then manually slid forward to the stop position, wherein the front end of the bolt member abuts the eyeiet 33 and displaces it forward away from the terminal end of the shank member by a predetermined distance, as shown in Fig.7. The eyelet of the penetrater member carries a bight of the obturater strip out from the bore of 3(~ the shank member The fore end of the shank member is ~ub~cu,u~ ly extracted from the tire wall, preferably by a series of slow twists and pulls. The obturater strip is grasped and retained by the tire wall due to the greater width of the bight of elastic strip and the uulll~J~ca~;ull ofthe tire wall thereon. As shown in Fig.8, the penetrater member remains within the tire and a substantial length of obturater strip extends outside of the tire wall, 35 which is sui~ u~ ly cut off with a suitable hand tool. More ~,u~ tio~al repair implements utilize a far thicker obturating strip which is harder and far more difficult to WO 95130s3s cut. Note that the rotation insertion of the penetrater member 30 through the tire ~ub~ lly scores the sides of the puncture aperture due to the cutting threads thereon which aids in providing a reliable seal around the obturater strip. Also the presence of the attached penetrater head prevents any possible egress of the obturater strip to the outside 5 of the tire.
The foregoing description should not be construed in a limitative sense but rather as being exemplary of the concepts embodied by the present invention, with the actual spirit and scope thereof being determined by the appended claims and their legal equivalents.
