Filed Oct. 19, 1956, Ser. No. 617,043

1 Claim. 01. 36- 42) The present invention relates to a heel construction and particularly to a heel shoes;

It is desirable for style and dress to change the heel of a womans shoe either to change the overall decorative appearance thereof or to modify the same to cause it to conform with different styles or appearances of other garments.

However, considerable difficulty has been experienced in that while heels are replaceable the changed heel is not firmly secured in position and furthermore there is considerable difiiculty in replacing the heel, requiring the use of toolsor diflicult manipulative operations.

It is therefore among the objects of the present invention to provide a novel, replaceable heel construction and particularly a metal finding, useful in association therewith which will permit the heel to be readily replaced and removed and which may be readily operated by the wearer thereof without tools or manipulative d-ifliculty.

Another object is to provide a novel replaceable heel construction and a novel metal finding to be associated therewith which upon simple operation may permit detachment of one heel and replacement by another heel with assurance that the heel will be firmly and definitely secured in position and with the further assurance that once secured in position it will not tend to loosen upon wear, walking of normal usage.

Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this rnore detailed description is given by'way of illustration and explanation only and not by way of limitation, since various changes therein maybe made by those skilled in the art without departing from the scope and spirit of the present invention.

.,In accomplishing the above objects, it has been found most suitable to provide a plate structure attached to the upper rear portion of the shoe and particularly the portion thereof directly above the heel with another plate positioned on the top of a replaceable heel. The upper plate is desirably associated with the rear portion of the metal shank and conforms thereto and is locked in position with respect thereto. The upper plate attached to the rear portion of the base of the shoe upper above the heel will carry a pivotal arrangement with a rotatable cam element while the lower plate on the top of the re movable heel will have a recess to engage and cooperate with the cam portion which is reciprocably and rotatably mounted upon the upper plate.

The rotatable cam element is desirably provided with a swinging tab mounted upon an upper element which is readily accessible on the interior of the shoe at the heel thereof and which when lifted up will enable rotation of the cam or vertical reciprocal movement of the cam, thus enabling locking and unlocking of the heel from its connection at the rear of the shoe. The lower plate on the top of the removable heel is desirably provided with a'half moon or oif-round-shape opening which will engage the cam, locking the cam in one position, and

Figure 7 is a top plan view of the top of the heel, looking downwardly from line 7--7 of Fig. 3, showing the locking cam arrangement when removed from the heel; Q

Figure 8 is a perspective separated view showing the various elements of the locking arrangement before assembly in the construction of Figures 1-6; and

Figure 9 is a perspective view upon a small scale of the steel shank used in conjunction with the heel locking arrangement of the present invention.

Referring to Figs. 1 to 3, there is shown a shoe A having a detachable heel B. The shank C is mounted in the shoe structure A between the insole lining D and the sole E. g

The heel locking means to which the present invention is particularly directed has an upper plate F which con forms inshape, size and rivet or nail openings to the rear plate G of the shank C. The plate F carries the cam H which in turn is mounted within or on the upper collar J. The upper collar J carries the handle member K. The lower plate L has an off-center opening M and a stop member N to cooperate with the cam H,

Referring specifically to the construction shown in Fig. 8 the cam H has a half-circular cylindrical portion 10 ofslightly less diameter than the periphery 11 of the opening M and the fiat face 12 of which will pass inside of the edge 13 of the opening M of Fig. 7. It will be noted that the opening M (Fig. 7) also has a semicircular enlargement 14.

The upwardly extending stud portion 15 will pass up through the opening M, the central large opening 16, the large opening'17 in the rear plate portion G of the shank C (see Fig. 9) and the central opening 18 in the element J to the upper portion of which it will be pinned in position as indicated at 23. The element I will have four openings 19 to receive the lock pin 20 and the limit pin 21. There will be two diametrically opposite lock pins 20 and two diametrically opposite limit pins 21. The reciprocating handle portion K has a liftable tip 22 which can be rotated upon the hinge pin 24 so that it is accessible from the interior upper portion of the shoe, as shown in Figs. 1 and 2. By means of the

pins

20 and 21 sliding vertically in the holes 19 it is possible to elevate or depress the upper member K in either the elevated tion G of the shank C conforms to the plate F and is held in position above the plate F as shown in Figs. 2, 3 and 5 by pins, screws or rivets extending through the front trio 4 of holes 36 and the rear trio of holes 37 in the plate G and the front trio of holes 38 and the rear trio of holes 39 in the plate F.

The plate F will also have two forward downwardly projecting pins or studs 40 and two rear downwardly projecting pins or studs 41. These

studs

40 and 41, respectively, are inserted and located in the holes 42 and 43 at the front and rear of the plate L in the heel, as shown in Fig. 7. The plate 7 will be held in position by the screws 44 which pass through the openings 45 in the bottom plate L.

Referring to Figure 6, the locking pins will be in the positions indicated at 48 which is 90 removed from the locking position.

The limit pins 21 will limit the movement of the element K to 90 upon locking or unlocking of the cam H. The rivets which extend through the

holes

36, 37, 38 and 39 are shown at 49 in Fig. 5.

Referring to Fig. 4, the stop plate may be welded or otherwise permanently mounted on the underside of the plate L. The cam will be stopped at one side .by contact of its corner 50 against the edge 51 of the stop plate. In the other direction, the corner 52 will be received in the annular recess 53 and act as an opposite stop which will give the camming swing of about 90 from locking to unlocking position. In unlocked position the corner 52 will be in the recess 53 and the cam may be thrown out of opening or hole M. In the other position, the shoulder 54 on the top of the cam, as shown in Fig. 8, will fit under the edge of the hole M and lock the heel securely in position.

In assembly, the shank portion G and the plate F are riveted in position through the

rivet holes

36, 37, 38 and 39 by the rivets 49 as shown in Figs. 2 and 3.

The plate F will have been previously assembled with the cam H, the collar I and the handle element K by the peaned-over connection 24. The rear of the shoe will have been previously provided with an opening as indicated at 62 to receive the assembly of K-J. The sock lining D may be readily lifted to give access to the unit K-I and to rivet the handle member 22 upon the hinge pin 23.

Normally, the handle 23 will be pushed downwardly as shown in Figs. 1 and 2 and will be elevated, as shown in Figs. 3 and 8, when the cam H is to be moved from locked to unlocked position and when the heel B is to be removed or replaced.

The assembly of the heel plate L will take place by inserting the screws 44 in the openings 45. The heel will be recessed as indicated at 35 and also as indicated at 63 to receive the cam H, as well as the plates F and stop N.

When the heel is locked in position the shoulder 54 will be under the edge of the opening M with the corner 50 abutting the edge 51 of the stop plate N. This locked position is shown in Figs. 2, 4 and 5 At the same time the studs '40 and 41 of the plate B will project into the openings 42 and 43, as shown in.

Fig. 4, latching the plates F and L together so that they cannot swing in respect to one another with the plate F already being held fixedly in position by rivets 49 in respect to the shank portion G.

In this locked position the handle element K will be down against the collar J and the cam H will be down in the recess 35, as indicated in Figs. 2 and 5.

Now, to remove the heel, the lining-D will be lifted as well as the handle 22. V l

With the handle 22 in the position as shown in Figs. 3 and 8, the upper element K is lifted or elevated from the element I which will lift the lock pins 20 out of the holes 47 and the structure K-J-H will be free to turn on the shaft 15 which extends through the fixed openings 16 in the plates F and 17 in the shank portion G.

This cam will then turn from the locked position of Fig. 4 until its nose 52 fits into the recess 53 of Fig. 4 whereupon its

edges

10 and 12 will match the edges 11 and 13 of the hole M.

In this position the cam H may be lifted out of the hole M, releasing the heel B from the upper A with the

studs

40 and 41 disengaging from the holes 42 and 43.

The separation will take place as shown in Fig. 3.

To reassemble a new heel, the new heel as shown in Fig. 3 is moved upwardly against the cam H so that the cam II will move into the hole M. At this moment the element K is lifted from the element 1, as shown in Fig. 3. Then the element K is pressed down against the element J, causing the lock pins 20 to be ready upon turning 90 to fit into the holes 47 with the

studs

40 and 41 fitting into the holes 42 and 43. When the cam H is turned so that its nose 50 hits the edge 51 of the lock plate A the new heel will be firmly locked in posi- It will be noted that the device is shown as below the sock lining D, but the sock lining may be lifted up or a hole may be cut therein to give access to turntable flap 22.

Of the four

pins

20 and 21 arranged in diametrically opposite pairs, the two pins 20 which are smaller in diameter but longer will act as lock pins fitting into the holes 47 to lock the device into position (see Figs. 6 and 8).

The edge 14 is a bearing for the shaft 15. Instead of the peaned-over portion 24, a taper pin may be driven through the shaft 15 and the collar J to hold the assembly together.

The insole R will carry the elements I and K as shown in Figs. 2 and 3 in the opening 62 in the insole R.

The steel shank C is attached to the insole R by cement and tacking at 61. The rear portion of the steel shank is mounted in position when the rivets are driven through the

holes

38 and 39 of the upper plate F and 36 and 37 of the rear steel shank portion 36.

The filler portion S is applied above the outsole E over the shank, but may be omitted if the upper part is cut down or routed out sufiiciently as indicated at 63 in Fig. 3.

The plate L must always be recessed below the plane of the top of the heel to a depth equal to the combined thickness of the three metal elements. In the preferred construction the three plates G, F and L will all be received in the recessed upper portion of the heel.

It is thus apparent that the applicant has provided a simple replaceable heel construction and the particular assembly thereof which may be readily associated with womens shoes and which will permit ready replacement of the heels without special tools or without any special,

permanently nailed or screwed to the rear of the upper;

The amount of turning from unlocked to locked position as shown in Figs. l-9 is between and but this amount of turn may be varied without changing the essential features of the present invention.

What is claimed is:

In a shoe having an upper and a replaceable heel,

means for removably mounting said heel on said upper,

5 said means including a shank in said shoe upper, a plate fixed to said shank, said shank and said plate each having an opening aligned with each other, a rotatable cam, having a locking shoulder, extending through said aligned openings, means on said plate for holding said cam in operative position, said cam holding means including a handle, a second plate mounted in said heel, said heel plate having an opening therein, adapted to be aligned with the openings in said first-mentioned plate and said shank, adapted to receive said cam, and a locking memher in said heel adapted to cooperate with said shoulder of said cam to hold said cam in locked position, said shoulder adapted to be moved into and out of contact with said locking member to hold said heel in position on the shoe or to permit the removal thereof, respectively, by turning said handle of said cam holding means.
