Patented Oct. 28, 1930 TENT OFFICE J'OHANN. EILERS, F NEUSUDENDE POST RASTEDE, GERMANY WEB FOR SWIMMING Application filed J'anuary3, 1930. Serial m. 418,347.
This invention relates'to a web attached in a suitable manner above the ankles adapted to spread after the manner of an umbrella as soon-as the legs are extended and to-collapse when the legs are being bent. It is evident that by this device a considerably greater swimming speed is obtained without substantially increasing the exertion of energy, as the comparatively small pressure surface which the sole of the foot together with the leg can oppose to the water is enlarged or completed in a certain measure by the stretched web. The device does not impede walking on the land, the stretching stays of the web then hanging down. Be-
sides the stretching stays no other stays are necessary, as the Web is maintained in the stretched position by the pressure exerted upon the water when swimming. Guide stays, strap connections or other auxiliary means, which might interfere with the free movability of the web, designed for preventing the device from turning over, are not required, as thelatter function is carried out by the stretching stays which find support on the holding ring of the device. i
An embodiment of the invention is illustrated by way of example in the accompanying drawing in which; I
Fig. 1 shows the web in top plan view spread out.
Fig. 2 shows the device in inoperative position, the operative position of one stretching lines.
Fig. 3 is a side elevation and Fig. 4 a front elevation, illustrating the fastening of a stretching stay directly to the steel band placed over the leather strap, the operative position of the stretching stay being indicated in Fig. 3 in dash lines. The device consists "of a leather strap 2 designed'to be placed around the leg and having flaps 3 covering the joint closed by lacing 4:, said strap being preferably lined the stretching stays.
elevation in the stay being indicated in dash with soft leather, of a thin resilient steel i band 5 placed on the strap 2, of vertical plates 6 fixed by rivets 9 on said steel band, and of stretching stays Thingedly mounted at 8 one on the lower end of each vertical plate A piece of fabric 10, forming the web proper, is held at its upper edge between the leather strap 2 and its lining. This piece of fabric 10 is slit between the stretching stays 7 at the right and left of the joint of the leather strap 2, the two edges of the slit being preferably connected by a lace 13 located in hollow seams 12 on the outer edge of the piece of fabric 10. The upper end of each stretching stay 7 has a nose 14;,
designed to prevent the stay from being lifted to above thehorizontal plane. The outer ends 15 of the stretching stays are connected to the web proper 10 by sewing or in any other suitable manner.
The steel band 5 may have on its lower edge downwardly extending tongues 16 forming hinge sleeve for the hinge pins of In this form of construction shown in Figs. 3 and 4 the verticalplates 6 are omitted.
A device designed to facilitate swimming is attached on each leg of the swimmer above the ankle. Owing to the lacing the device can be adapted to the thickness of the leg.
The stretching stays are preferably loosely mounted in their hinges, i. c. with slight lateral play, so that the web proper, i. e. the piece of fabric 10, can be re-stretched.
1. A device (web) designed to facilitate swimming attached above the ankle so that at the extending of the leg the web is spread but collapses at the bending of the leg, comprisingin combination a leather strap closed by lacing, a piece of fabric forming the web proper attached at the upper edge on the inner side of said leather strap, a'thinsteel I hand on said leather strap, stretching stays hingedly mounted on said steel band and at- JOHANN EILERS.
