I EXCHANGEABLE HEEL FOR BOOTS AND SHOES Filed May 24, 1930 awuentoz Patented Nov. 17, 1931 UNITED STATES PATENT OFFICE EXCHANGEABLE HEEL FOR BOOTS AND SHOES Application filed. May 24, 1930, Serial No. 455,175, and in Czechoslovakia August 30, 1927.
The present invention relatest'o a heel for boots and shoes of which the lower part or pad can be exchanged. By means of the present invention there is obtained both a I readily detachable connection between the pad and the remainder of the heel and a low cost of production of the separate parts.
The previously known detachable heels are inconvenient in use by reason of the numerous mechanical connecuing parts and more expensive to produce so that they have not been used to any considerable extent in practice. The heel produced'according to the present invention, however, can be applied and detached readily, while the parts thereof are cheap to produce.
The detachable heel part or pad is previously provided with a suitable number of projecting sleeves which are secured to the pad in a particular manner and when applying the pad are forced into corresponding sleeves which are fitted and secured in the material of the heel whenthe latter is being manufactured. Into the centre of the heel is fitted a screwed sleeve in which is adapted to move a screw of which the head bears against the pad. "When the latter is to be removed the screw is moved slightly outwardly by means of a suitable tool so, that its head presses the pad outwardly to such an extent away from the remainder of the heel that the pad canloe easily removed by hand and replaced by another pad.
One form of construction of the invention is illustrated in the accompanying drawings wherein:
Fig. 1 shows a vertical section of the detachable pad on the line B-B of Fig. 2, V
Fig. 2 is a cross section on the line AA of Fig. 1,
Fig. 3 shows an underside vi w of a pad in position,
Figs. 4-8 show altered forms of execution of the fastening of the sleeves or taps in the pad,
Fig. 4 showing a form to be used for leather pads in section on the line E-E of Fig. 5,
Fi 5 the pad seen from the underside,
Figs. 6 and 7 showing in a similar way one form for pads of caoutchouc, Fig. 6 being a section on the line GG of Fig. 7,
Fig. 8 shows in section another form for caoutchouc pads.
In Fig. 1, 1 indicates the heel itself of leather or wood, 2 the leather pad applied thereto. The latter when being manufactured or in every case before use is provided with three or more projecting sleeves 3, eX- tending towards the heel, each of which, at its end adjacent the pad 2, is provided with a flange 3. These sleeves are preferably secured to the pad by passing tapered pins or pegs through suitable holes in the pad and forcing them into the sleeves 3 so that they are firmly connected to the sleeves and the pat material thus forming a secure connection between the pad 2 and the sleeve 3. In this form the pad is ready for application and is placed on the market in this form.
For the reception of the sleeves 3 the heel 1 is provided with a corresponding number of bushes 5 of which the internal diameter is a close fit on the outer diameter of the sleeves so that the clamping action or rriction between these two members is sufficient to retain the pad on the heel. To apply the pad it is therefore sufiicient to force the sleeves 3 into the bushes 5.
in order to secure the bushes 5 in the wood or leather heel 1 tlieir forward cylindrical end, before driving them into the heel, may partly have fitted therein tapered plugs 6 of metal. I
WVhen driving in the bush the tapered plug is forced completely or almost completely into the bush thus enlarging the front end thereof, as shown in Fig.- 1 so that it is impossible for the bu sh to become disengaged from the heel.
V In order to facilitate the removal of the detachable heel part or pad from the remainder of the heel the following arrangement is illustrated,projects beyond the surface of the heel and bearsagainst the inner sur- .cc of the pad 2. The-screw is provided with-a cen tral hole 10 while opposite thereto the pad 2 is provided with a hole, gradually reduced towards the outside of the pad and normally closed by a plug 11 of rubber, inserted from the ii. so as to prevent the entrance of moisture. By means of a pointed object, for example a prong formed on a key or spanner adapted to be litter into the hole 10, the plug Y and the key can 11 can he removed. eas" be fitted into the hole 10 of the screw 8. vVhen unscrewing the screw 8 its head 9 forces the pad 2 away from. the heel so that the pad can be easily removed by hand and replaced by another pad.
The pad may he provided with a celluloid so 1:2 on its side turned towards the heel to event the entrance of moisture.
In the example shown the disc surrounds both the sleeves 8 and the head 9 of the screw. The head 9 may however tit into a recess in the material ofthe hee 1 in which case the disc 12 only serves to rround the sleeves 3 and a. central hole serving for the passage of the key.
'1 he flanges 3* may also he provided with teeth. grooves or the like on the side turned towards the pad so as to enga more iir sly with the niatci'al of the pad.
In the use of wide heels a larger number of connecting members 3 and 5 is used, for example live to eight.
According to Figs. 41 and 5 screwthreaded taps 3 are inserted into the fixed heel portion bv means of corresponding holes arranged in the leather pad the said taps are provided with conical flanges at the upper ends of their scrcwthreaded portions to serve as siu'iporting mean for th pad.
According to 6 and 7 the taps 3 have inside the caoutchouc pad 2 a conical circular flange 14, and in their lower end a head 15. For these taps holes 16 are formed from outside in the caoutchoue pad, these being provided with an exterior enlarged part for taking up the head 15, and an inner, narrow part for taking up the neck of the tap lying between the flange and the head 15. These taps are from outside pressed through the holes in the caoutchouc, the conical flange 1% extending through the narrow part of the hole, which thereupon is drawn tight together about the neck of the tap, so that the tap gets an exceedingly solid position, being at one end supported by the flange 14 and at the other end by the head 15. After the fastgning of the pad the outward part of the holes 16 are tilled out with a caoutchouc plug corresponding to the plug 11 in the central hole of the pad. According to Fig. 8 the taps 3, being provided with a relatively broad head 17, are molded into the caoutchouc pad by the making of this. Each of these taps is made in one piece by pressing or the like, so that the tap stalk itself cannot be detached by the use of it from the head, and the pad thus be lost.
The disc of celluloid 12 is suitably made use of by the form of execution shown in Figs. t and 5, while it is not thought to be used by the pads of caoutchouc. The forms of execution shown in Figs. 4-8 make pos sible a still cheaper making of the metal parts than the one shown in Figs. 1-3. Besides it will be understood that all the parts of the device may be easily produced mechanically at a low cost.
The arrangement can also be used easily in that when applying the detachable part it is only necessary to press it firmly against the heel and for the purpose of removal the screw 8 is turned a few times thus releasing the pad and enabling it to be readily removed by hand.
It is also of advantage in connection with the invention not to effect the connection of the parts by springs as these are weakened in use thus rendering the heel part or pad liable to be lost.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. A heel for boots and shoes with a detachable wearing pert or pad adapted to be brought into engagement with the rigid heel part by pressure, characterized in that in the rigid heel part are provided smooth bushes 5 for the reception of projecting sleeves 3, previously secured to the detachable heel part or pad 2, and an internally screwed centrally disposed bush 7 for the reception of a screw 8 adapted to be actuated from the outer side of the heel part or pad 2 when in position and when unscrewed serves to separate the part 2 from the rigid part 1.
2. A heel for boots and shoes according to claim 1, characterized in that the bushes 5 are secured in the heel 1 by means of tapered metal plugs 6 which are first partly fitted into the forward ends of the bushes and when driving the bushes into the heel are forced into the bushes and expand these.
