REPLACEABLE HESLS Fox SH01-:s

Filed Nov. 1:5, 1959 INVENTOR `ATTORNEY United relates i te' delantal-51e aiidi replaceable heelsffoi"shoes. n y,

lfhas he'etofebee prp's`ed` 'v heels for replacem'etl't when' excessive t the str tures as heretofore pro`pvts`ef'ill have n rlrduly cnipli "tedfso as toA be'costly fo manufacture;

id not etairiwth'e' heel tread members( in `iiel position' in ycomponent parts and inwhich the. com nentfpartsfare the: -h'el tread member tends to' make the heel `Vtread r'nei'nber` tighter.

: Itis the further object of Athe ip`r =;sent invention to provide na construction having a replaceablegheelgtread .member and an improvedgonrletina retaining meehaaism between the heel treed. and the rertigriivf the lieel secured to the sole of the shoe.

Other objects and advantageous features of the invention will be apparent from the description and claims.

The nature and characteristic features of the invention will be more readily understood from the following description, taken in connection with the accompanying drawings forming part thereof, in which:

Figure 1 is a top plan view of the heel base portion of a shoe removed from the shoe and having the heel tread member attached thereto, parts being broken away to show the details of construction;

Fig. 2 is an underneath plan view of the heel base portion of the shoe, the heel tread member being detached therefrom;

Fig. 3 is a top plan view of the heel tread member removed from the shoe;

Fig. 4 is a vertical sectional view, enlarged, taken approximately on the line 4`4 of Fig. 1;

Fig. 5 is a vertical sectional view, enlarged, taken approximately on the line 5--5 of Fig. 1;

Fig. 6 is a fragmentary sectional View, enlarged, taken approximately on the line 6-6 of Fig. l; and

Fig. 7 is a side elevational view illustrating the mounting of the heel tread member.

It should, of course, be understood that the description and drawings herein are illustrative merely, and that various modications and changes can be made in the structure disclosed without departing from the spirit of the invention.

Like numerals refer to like parts throughout the several vlews.

Referring now more particularly to the drawings, for

extendmsi upward y ICC l I 6 d 'te move' the spring-"reigponiogn iste mdesired position t`oY permitjfof locking, an actuatorpin' 30 is' provided; the inner' eiiidL 31 ef; which is vadapted4 tejien- `The pin has, intermediate .its f itds, ,an easetfprfiiail ing of the spring leg portion 25 in an open or disengaged position.

The pin 30 preferably has a slot 34 in the actuator end thereof for the insertion of a tool (not shown) to press the same inwardly and turn the pin 30 for engagement of the oifset portion 32.

A heel tread member 35 Iis provided which may be made of any desired material but is preferably made of rubber of the desired shape and has a body portion with a plate 36, preferably of sheet metal and formed as a stamping molded or otherwise secured therein. The plate 36 has a pair of spaced hinge projections 37 which are adapted to engage over the rear marginal edge 20 of the plate opening 19 to provide a rear hinge.

The plate 36 at the opposite or forward end is provided with a ledge 38 extending therefrom. The ledge 38 has a slot 39 formed therein with an opening 40 and an upper margin 41 downwardly inclined to provide a wedging action upon engagement by the spring leg portion 25.

The mode of attachment and detachment of the heel pad 35 will now be pointed out.

When -it is desired to initially apply a heel tread member 35 the pin 30 is pressed inwardly with a suitable tool (not shown) engaging in the slot 34 thereof, the otfset portion 32. being engaged at the recess 33 to hold the spring leg portion 25 away from the stop or limit tongue 27. The heel tread member 35 to be mounted is then brought to a position to engage the hinge projections 37 over the rear marginal edge 20 of the plate opening 19 and the ledge 38 is then moved upwardly through the opening 26, the slot opening 40 permitting the ledge 38 Patented July. 19, 196e heel tread member 35 will thus Vbe retained in tight fixed relation with. respect to theY heel base portionil. Y yIf replacement of the heel tread member 35 is` required by reason of wear, a tool, as previously pointed out,is

inserted in the slot 34 of the pin 30. The .pin 30 is pressed inwardly toV disengage the spring leg portion 25 from the margin 41. Upon turning of -.the pin .to engage the offset portion 32 Vat the recess 33, .the-heel' tread member 35 may be swung downwardly about the pivotal axis provided by the engagement ofthe hinge projections 37 with the edge 20fof the plate opening 19. Y

A new heel tread member 35 may then be inserted as previously explained and the pin 30 released so that the pin leg portion 25 can move to its locking position in the slot 3-9. Y

I claim:Y l Y 1. A heel construction comprising a heel base portion and a heel tread portion with interior facing parts, one of said portions haivng a plate secured on its facing part, said plate having spaced openings therethrough at Vopposite ends thereof, ysaid plate having a spring mounted thereon on la side face thereof opposite its facing part, said spring having a leg extending over said side face and in intersecting relation to one of said openings, the other of said portions having members projecting therefrom for pivotal engagement with marginal portions of one of said openings in said plate and a ledge spaced from said members projecting therefrom and insertable through the other of said openings in said plate, said ledge having a Atransverseslot for locking engagement by said spring leg.

2. A heel construction yas defined Vin claim l in which a -controlpin is provided in one of said portions for releasing engagement with Isaid spring leg.

3. A heel construction as defined inrclaim 1 in which a control pin is provided in one of said portions for releasing engagement with said spring leg and said pin has an offset part for holding said leg in'unlocked position.

vsaid plate has a struck up tongue on which said spring is pivotally mounted and said plate has a tongue limiting the movement of said spring leg in one direction.

5. A heel construction comprising a heel base portion and a heel tread portion with interior facing parts, said heel base portion having a plate secured on its facing part, said plate having spaced openings therethrough at opposite vends thereof, said plate having a spring mounted thereon on a side 4face thereof opposite its facing part, said spring having a leg extending'over said side face and in intersecting relation toV one of said openings, said heel tread portion having members projecting therefrom for pivotal engagement with marginalportions of one of said openings in said plate and a ledge spaced from said members projecting therefrom and insertable through the other of said openings in said plate and said ledge having a `transverse slot for lockingengagement by said spring leg.

isaid plate has a struck up tongue on which said spring is Apivotally mounted. Y
