Abstract
Description
- The present invention relates generally to improvements for a pocket sized footwear article of manufacture and more particularly to improvements whereby said footwear article of manufacture is placed in a folded condition following pivotal traverses so as to assume a pocket sized ⅓ dimension all as will be better understood as the description proceeds.
- 1. Field of Search
- In the prior art is patent application publication US 2008/0098616 of Leedy for “Roll Up Thong” made up of layers of thin flexible material having the ability to be rolled up for non-use storage. In the rolled up condition there is the tendency to unroll, and the diameter of the roll is not of a desirable minimal size.
- In prior art patent application US 2007/0204483 of Kirsch et al. for “Flexible Shoe and Container” in the specific embodiment of a thong or flip-flop, there is specific reference to being folded as well as rolled, but to be rolled the thong is also of thin flexible material, it thus lacks the ability to withstand the abuse of wear on walking surfaces such as concrete sidewalks and the like.
- Broadly, it is an object of the present invention to overcome the foregoing and other noted shortcomings of the prior art.
- More particularly, it is an object to provide three adjacently spaced apart stiff plastic constituted panels to withstand the abuse of wear positioned lengthwise of the thong, and a top and a bottom elastomeric ply utilized to sandwich the plastic panels therebetween, and at the bridging of each spacing site between the plastic panels, there functionally exists an axis for pivotal traverses. Partaking of the pivotal traverses results in a non-use folded condition of ⅓ the dimension of the thong.
- The description of the invention which follows, together with the accompanying drawing should not be construed as limiting the invention to the example shown and described, because those skilled in the art to which this invention appertains will be able to devise other forms thereof.
-
FIG. 1 is a perspective view of a foldable flip-flop according to the present invention preparatory to its folding mode; -
FIG. 2 is an exploded view of the flip-flop illustrating the construction thereof; -
FIG. 3 is a partial cross-sectional view taken along line 3-3 ofFIG. 1 ; -
FIG. 4 is a similar partial cross-sectional view taken along line 4-4 ofFIG. 1 ; -
FIG. 5 is a perspective view of the flip-flop in its initial folding mode; -
FIG. 6 is-a perspective view of the flip-flop in its final folding mode; and -
FIG. 7 is a perspective view of the flip-flop in circumstances using to advantage the folding mode thereof. - Shown in the drawings is a footwear article of manufacture, generally designated 10, popularly known as a flip-flop (as designated in RANDOMHOUSE WEBSTER'S College Dictionary at page 509 right column) which is sized to fit in a female's 12
pocket 14 or pocketbook when not in wearing use on herfeet 16. - To achieve this desirable downsizing, flip-
flop 10 is constructed of three stiff plastic constituted panels, namely atoe panel 18, an arch or medial panel 20 and aheel panel 22, thus measuring from toe to heel adimension 24 correlated to average sizes of thefeet 16 of thefemale user 12. The plastic construction material of each of thepanels - More particularly, in the flat the
toe panel 18 is located adjacent the middle panel 20 so that toe panel edge 26 and front middle panel edge 28 bound afirst clearance 30 therebetween and located adjacent middle panel 20 isheel panel 22 so that rearmiddle panel edge 32 bounds asecond clearance 34 therebetween withheel panel edge 36. - As noted by the reference arrows, the
dimension 38 oftoe panel 18 is a fraction of and no greater than ⅓ the toe to heeldimension 24, and likewise of thedimension 40 of middle panel 20 and thedimension 42 ofheel panel 22, so thatfolding toe panel 18 as noted byarrow 44 upon the middle panel 20 and then foldingheel panel 22 as noted by thearrow 46 upon the bottom 48 of thetoe panel 18 reduces the size of the folded condition of the flip-flop 10 to a width size dimension 50 of the trouserrear pocket 14 as best noted inFIG. 7 by the position-inserting dot-dash arrows 52. - Continuing with the description of the folding mode, two identical shaped
upper ply 54 andlower ply 56 arc adhesively secured, usingadhesive coats 58, on opposite sides of thetoe panel 18, middle panel 20 andheel panel 22 and over the first andsecond clearances plies pivotal traverses axis clearances - From the foregoing it should be readily understood that preparatory to non-use the downsizing of the flip-
flop 10 is sized to fit in thepocket 14 and preparatory to wearing use it is readily unfolded to the toe to heeldimension 24 to be held bythongs 64 attached, as at attachment sites 66 to the user'sfeet 16. - While the pocket sized footwear article/flip-flop herein shown and disclosed in detail is fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to be understood that it is merely illustrative of the presently preferred embodiment of the invention and that no limitations are intended to the detail of construction or design herein shown other than as defined in the appended claims.
