Abstract
A structure of a low to high heel shoe wherein a sole (figure 1) having two demicircular ~D~ shaped punched holes on either side of the shank it formed in the rear of the shoe area, to receive a bolt fitting (figure 2) having a bight slot (A) and two opposing distal members, fitting through the punched holes and over the shoe shank thereby adjoining to the heel.
Description
TITLE OF INVENTION
Rotationally Detachable~low to high heel shoes Inventor: Lisa Walker FIELD OF I~iVENTION
The Rotationally Detachable low to high heel shoe facilitates a means to create individual style~regarding footwear, using a mode that is interchangeable and detachable. Providing a necessary means for change by the consumer in its unyielding desire to create inclividual style of shoes or boots in relation to clothing.
BACKGROUND OR RELATED ART
The following listed prior art has come to the attention of applicant. The prior art is believed relevant to, but patentably distinguishable from, the present invention and is being cited pursuant to Rule 91. A copy of each prior art publication is enclosed and its relevance ,is discussed below. .
# 4,219,946 Shoe w/ an interchangeable heel, ~Uwe Baum, Sept. 2,1980 # 4,363,177 . Style convertible footwear, Leslie Boros, Dec. 14,1982 # 4,400,893 Shoe w/ removably mounted heel, Nicola Musei, Aug. 30, # 5,477,625 Interchangeable shoe, Michael Goldsmith, Dec. 26,1995 Baum creates his design with a rigid plate in the sole of the heel. This could potentially come away from the shoe because,of the dissimilar materials, one of rigidity and one of flexibility. Also, much work and excess manufacture would constitute this design, leaving the cost of the product exorbitant. My invention solves this problem due to the use of conventional materials in making the shoe, there are no pieces, which could come away from the shoe, and the easy motion of rotating the heel on and off serves the .
consumer with a very low change-over time.
Boros creates a similar design to that of Baum having the added cutout and insertion of a square like notch and indention mounted ~to the heel and shoe respectively. There is a notch like protrusion, which could break off during normal wear. This leaves the desigwunfavorable. The addition of an extra pin like feature leaves the design unsightly with multiple parts to keep inventory of. And also creates a time consuming style changeover. My invention uses no protrusions, which could break off during normal, wear and have no extra pieces which could become lost, and the easy motion of rotating the heel on and off serves the consumer with a very low change-over time:
Musei uses a small, slim screw that one must insert down through the sole and into the heel with an additional tool. This design is also flawed dtie to the small screw, which will split fibm the heel because of direct pressure by wearer, during normal wear. The design is mostly time consuming for consumer. In addition, he uses a simi-rigid plastic sole that is unmanageable for lowering the heel. My invention uses a very thick bolt-fitting that could not potentially break, there are no tools needed to change heels, and the easy motion of rotating the heel on and off serves the consumer with a very low change-over time.
Goldsmith created a design totally unstable and unsightly. This design uses rubber which is extremely flexible lending no support to the wearer. An added inconvenience is the nuisance of a strap that purportedly secures the heel. This strap is objectionable due to the apparent volatility of movement from normal wear. The snap provides easy disengagement of the wearer from the shoe during normal wear. My invenfion solves these prpblems by creating a conventional to~king shoe using the conventional shoemaking materials, ah~eady in use and the easy motion of rotating the heel on and off serves the consumer with a very low changeover time.
Rotationally Detachable Low to Hi»h Heel Shoe DETAILED DESCRIPTION OF THE INVENTION
i Referring to the drawings for a skilled artisan to manufacture and give 3 , a layperson a definitive narrative, FIG 1 shows a view of the shoe sole area 4 and punched "D" shaped holes B and Bl near the back of the shoe where the .
heel of the wearer will rest. FIG 3 and FIG 4 shows a view of the back of a completely constructed rotationally detachable low to high heel show with the bolt fitting 2 bonded to the. shoe sole FIG 1, and a view of the injection g molded shoe heel which will adjoin with the bolt fitting 2 by a simple rotation, connection the two.
11 ~e ~~ ale FIG 1 is made of conventional materials; preferably leather. By reference, the shoe sole comprises two "D" shaped punched B
14 wd B1 in juxtaposition forming a backward "D" shape and a forward "D"
shaped at either side of the shoe's shank A, nearing the back of the sole area.
16 It is possible for the punched holes to be rounded or squared; however for the 17 ~ aesthetic appeal of a finished product the "D" shape is preferred due to its 19 co~slmnding shape to the bolt fitting's opposing distal ends C and C1.
_ To form a complete shoe sole FIG 3 a~male threaded bolt fitting FIG
21 2 must pass through the two "D" shaped punched holes B and Bl. A bolt fitting in FIG 2 shows a bight slot D. and two opposing distal ends C and Cl.
Bolt fitting FIG 2 is straddled over the shank A and through the two "D"
~ shaped punched holes B and B1 which is permanently bonded using glue or 26 other fastening options. It is preferable for the bolt-fitting FIG 2 to be 2~ manufactured of rigid plastic or polymer.

29 The embodiment of a complete shoe sole FIG 3 with the shoe heel FIG 4, includes an injection molded shoe heel having female threads to 31 apt ~e bolt-fitting FIG 2 and its two opposing distal ends C and Cl. The 32 shoe heel FIG 4 will be tapped having female threading with a downward 34 chc~m' fashion or countersunk depression so that the bolt fitting FIG 2 and 3'7 3g its opposing distal ends C and Cl are oriented inside the shoe heel joining 39 thereto. Preferably, this threading will remain at a static measurement after 40 ~e'~j~on mold has been obtained. Finding the longitudinal axis extending 41 ~~ ~e ale where the "D" shaped holes B and Bl will remain static 42 ~o~g ~e connection of a bolt fitting FIG 2 and shoe heel FIG 5. One 43 ~~ ~ m~ematics or engineering will be able to obtain such measurement without difficulty.
45 FIG 6 shows a top sand side view of the thin flat horizontally founded 46 h~ of the bolt-fitting FIG 2, which will cover a generous area. of the shoe 4~ sole FIG 1, after the bolt fitting FIG 2 is permanently aced to shoe sole 4g FIG 1. The rounded head FIG 6 is preferred as opposed to squared or other 49 g~m~c shape. By rotating the shoe heel FIG 6 clockwise onto the bolt 50 fig FIG 2 until rotation is stopped, a complete shoe is read for wear.
51 Conversely, by rotating the shoe heel FIG 4 counter clockwise until the shoe 52 ~ heel is disjoined from the shoe sole FIG 3 and exposing the bolt fitting 53 will provide the wearer with a new option for joining a second differently .54 styled shoe heel FIG 4.
55 Figures 2- bolt fitting and 4- heel, may be formed of a rigid plastic or .56 s~~~.
It is understood that for adjoining and disjoining, only the heel needs rotation.
