Claims. (Cl. 36-36) 4 The present invention relates to a readily replaceable heel for shoes and more particularly to a mechanical connection between the portion of the heel which engages the ground and the base of the heel so that when the heel tap becomes worn it can be readily replaced without requiring the services of a professional.
' Heretofore, various means have been provided to secure a heel to a shoe and some have included mechanical connections by which the wearer of the shoe may replace the heel tap without the services of a professional, but the structures heretofore used have been inefficient for the purpose of ease of replacement.
It is an object of the present invention to provide a releasable connection between the heel tap and the base of the heel which can be readily operated by the wearer of the shoe without the necessity of loss of time and the expense of having professional services.
Another object is to provide a releasable connection for attaching two elements which securely retain the two elements in connected relation and also provides for selective separation when desired.
Other and further objects will be apparent as the description proceeds and upon reference to the accompanying drawing wherein: I
FIG. "1 is a perspective of a portion of the shoe with the present invention applied to the base of the heel and to the heel tap, showing the parts in separated position with the detent operating slide in position to release the detent; 0
FIG. 2 is a perspective of a fragment of a shoe, showing the heel secured to the shoe in its operative relation;
FIG. 3 is a longitudinal section taken substantially on line 3--3 of FIG. 2, showing the detent in its operative position and the detent release in its operative position and illustrating one of the struck out portions connecting the attachment plate to the heel tap;
'FIG. 4 is a section similar to FIG. 3, showing the detent release in its detent releasing position and showing the heel in its semiattached condition, illustrating the stop action of the detent on the detent operating slide which prevents unintentional complete removal of the heel tap;
FIG. 5 is a section taken substantially on line 55 of FIG. 2, showing the channel connection of the attaching plate to the base plate and showing the detent in the channel and in the slot in the detent'operating slide; and
FIG. 6 is a section taken substantially on line 6 -6 of FIG. 3, showing the channel which maintains the slide .in its proper operating position with the slide in its inoperative position and the detent in its operative position.
Briefly stated, the present invention in a detachable heel structure for a shoe includes a base plate mounted on the base of a heel by means Qfstruck out portions with such plate having its back and side margins spaced from the corresponding margins of the base of the heel and being spaced from the base of the heel at least the thickness of the base plate. Cooperating with the base plate is an attaching plate secured to the heel tap within a recess in the heel tap by means of struck out portions of the attaching plate and such attaching plate carries a detent releasing slide which cooperates with a detent on the base plate for releasing the detent on the base plate to permit removal of the heel tap, the heel tap attaching plate having a channel-shaped margin which slideably engages the sides and back of the base plate, thereby pro- 3,077,680 Patented Feb. 19, 1963 2 viding for ease of attachment and detachment of a heel plate and permitting easy replacement without professional assistance.
More specifically, on a shoe 10 the usual heel base 11 is secured in the usual manner by nails or the like and mounted on the outer surface of such base 11 is a base plate 12 of a shape generally corresponding to the shape of the base of the heel with the front margin thereof substantially flush with the front of the heel and having a downwardly extending flange 13 for engagement with the front edge of a heel tap 14. The base plate 12 has its margins along the sides and back spaced from the heel base 11 by an amount substantially the thickness of the base plate 12 for receiving the inwardly turned channel of an attaching plate hereinafter described.
The base plate 12 is provided with struck out fingers 15 formed from the material struck out which leaves openings 16 with such fingers forced into the heel base 11 securing the base plate 12 to the heel base. It will be apparent that nails can be used in place of the struck out elements 15. Cut-outs 17 are provided to reduce weight and a detent 18 is formed by slitting the base plate along longitudinal lines which diverge toward the front edge and such detent is substantially rectangular and provided with flanges 19 adjacent the front end thereof. To increase the resiliency of the detent 18 a leaf spring 20 is mounted in contact with the detent 18 and held in position by a nail 21 passing through the base plate and the spring 20, the spring 20 being held in position to provide the desired resiliency in the detent, it being apparent that a recess 22 is provided in the heel base to permit retraction of the detent and a leaf spring seat recess 23 provides for the proper reception of the leaf spring 20 so that the desired resiliency is maintained. The front end of the spring 20 is held by tabs 19A struck out of the flanges 19.
The heel tap 14 is provided with a recess for receiving the tap attaching plate 24, which plate is generally the shape ,of the heel tap with its front .edge extending substantially flush with the front edge of the heel tap and its side and rear margins being of channel shape formed by a laterally extending channel including a top flange 25 around the sides and back of the attaching plate, which flange 25 is received between the heel base 11 and the corresponding side and back of the 'base plate 12 as clearly shown in FIGS. 3 and 5, whereby the attaching plate 24 can he slid onto the base plate 12 by a sliding movement of the attaching plate from the rear of the shoe toward the front of the shoe.
The attaching plate 24 is received within the .opening in the upper surface of the heel tap 14 as described above and is retained therein by struck out elements 26 which m1 around and clinch in the material of the heel tap 14.
Cut-outs 27 are formed in the attaching plate 24 and a portion of the material from the cut-outs forms flanges 28 which extend downwardly into a slide receiving recess 29 in the heel tap 14 and provide guiding action for a detent releasing slide 30. A longitudinally extending opening 61 extends from approximately the center of the attaching plate 24 to adjacent thefront of vsuch attaching plate terminating in a forward edge 32 providing a keeper which is adapted to be engaged by the fianges 19 of the detent 18. The'slide 30- includes a downwardly extending operating flange 33 which normally is received in a recess 34 in the front of the heel providing a smooth front edge as shown in FIG. 3, but the handle 33 can be operated by the insertion of a sharp instrument or a finger nail to cause the slide 30 to move to its operative position as shown in dotted lines in FIG. 3 pushing the detent 18 to its dotted line position, permitting the heel tap 14 to be slid rearwardly to the position of FIG. 4.
The slide 30 is provided with a detent receiving opening 35 which is adapted to register with'the opening 31 and the detent releasing slide includes an upwardly extending lug 36 at its rear end which is adapted to engage the adjacent surface of the detent 18 causing the detent to move to its inoperative position shown in dotted lines in FIG. 3. It will be noted that the front end of the opening 35 of the slide 30 is provided with a notch 37 leaving end portions adjacent the notch for engagement with the detent 18 and flanges 19 as shown in FIG. 4 so that the heel tap 14 cannot be completely removed as thedetent 18 abuts the front end of the opening 35 as clearly shown in FIG. 4 and to completely release the heel the detent must be pushed upwardly so that it is released from the front end of opening 35 and the heel tap can then be removed.
From the above descritpion it will be apparent that the invention is particularly efficient for ready replacement of the heel so that a person may maintain his shoes in a condition free of the down at the heels appearance.
It will be obvious to those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is illustrated in the drawing and described in the specification, but only as indicated in the accompanying claims. i
