Heretofore, roller skates have been constructed entirely of metal or plastic material and toe and heel straps have been attached thereto. Further, known roller skates have lacked any means to increase or decrease the swivel action of the wheelassemblies. The roller skate illustrated in the accompanying drawings is characterized by having relatively adjustable heel and toe portions and novel molded foot pads integrally attached thereto. The pads each have strap-like elements integrally molded therewith. The toe and foot portions each mount a resilient Wheel assembly which embodies novel means to facilitate adjustment to increase or decrease the swivel action of the wheel assembly. Also carried on the toe portion is a novel resilient frictional toe stop.

It is therefore an object of the invention to provide a roller skate of the character referred to.

Another object is to provide integrally molded heel and toe pad portions with strap-like elements.

Another object is to provide a roller skate with novel manually adjustable mounts for the wheel assemblies for varying the amount of swivel action afforded thereby.

Another object is to provide a roller skate with a novelly constructed toe stop.

Another object is to provide a roller skate of the character referred to which is not difficult or expensive to manufacture, may be adjusted readily to vary the amount of swivel action afforded its wheel mountings and which is very satisfactory in use.

The structure by means of which the above noted and other objects and advantages of the invention are attained will be described in the following specification, taken in conjunction with the accompanying drawings, showing a preferred illustrative embodiment of the invention, in which:

FIG. 1 is a side elevational view of a roller skate embodying the invention.

FIG. 2 is a top plan view of the skate.

FIG. 3 is a longitudinal sectional View of the skate.

FIG. 4 is a bottom plan view of the skate, showing one wheel broken away.

FIG. 5 is a transverse sectional view through the heel portion of the skate, taken substantially on line 5-5 of FIG. 3.

FIG. 6 is a transverse sectional view through the toe portion of the skate, taken substantially on line 6-6 of FIG. 3.

Referring to the exemplary disclosure of the invention shown in the accompanying drawings, and particularly to FIG. 1, the roller skate is comprised of a heel portion 11 and atoe portion 12, each having a wheel mounting assembly 13 on the bottom side thereof.

Referring now to FIGS. 3 to 5 in particular, the heel portion 11, includes a castmetal heel plate 14 having on its forward edge anelongated bar 15 which is inverted U-shape in section. It includes dependingmarginal flanges 16 that also extend along the under side ofplate 14. Theplate 14 also has, formed integral therewith, a tappedboss 17 and a substantially triangular shaped depending olfset 2 18. Arranged to lie flat over the top surface ofheel plate 14 is apad 19 preferably molded from suitable substantially stiff plastic material; This pad includes a dependingperimeter flange 21 which haslugs 22 integral therewith and which engage beneath the side marginsofheel plate 14. The pad is secured firmly to the heel plate as byrivets 23. Aheel strap 24, apertured at 25, (FIG. 1) to receive lacing tie string (not shown) is formed integral withpad 19.

Thetoe portion 12 has, as best shown in FIGS. 3, 4 and 6, a castmetal toe plate 26, also formed on its bottom face with a tappedboss 27 and a substantially triangular shaped offset 28. Theplate 26 has downwardly projecting upwardly opening channels 29 (FIG. 6) which receive slidingly the marginal flanges 1601? the bar ,15 when the heel and toe portions are matingly engaged in the manner best shown in FIG. 3.

In order to retain the heel and toe portions 11-12 in spaced adjustment, the top surface ofbar 15 preferably is serrated, as at 31 (FIG. 3) to receive in tight bearing thereagainst the head of an adjustingscrew 32 which is threaded into a tappedboss 33 on thetoe plate 26.

Arranged to lie flat over the top surface oftoe plate 26 is apad 34 of substantially stiff plastic material. This pad has on its side edges and below its bottom face,side flanges 35 that engage beneath the side margins of thetoe plate 26. In order to facilitate the mounting of thistoe pad 34, on thetoe plate 26, said pad is split longitudinally and each half is formed with overlapping integral eyelets 36 (FIG. 2) through which arivet 37 is passed for securing the pad to the toe plate. The assembled pad halves also each have a semi-circular recess on their mating edges to define a circular aperture 38 (FIG. 2) to permit access to be had to the adjustingscrew 32. Also, the pad has integral with each half, a toe strap-like element 39 having lacing apertures 41 therein.

Atoe stop 42 is carried on the front end of the toe portion. As shown, thisstop 42 is comprised of a circular body of tough wear-resisting material which is secured to the toe portion by abracket 43, abolt 44 being ex-* tended through the bracket and stop so as to facilitate its removal and replacement.

Theboss 17 and offsettriangular portion 18 of the heel plate and theboss 27 and offset triangular portion 28 of the toe portion afford means for mounting the wheel mounting assemblies 13. These assemblies are structurally alike and only one will be described, the description being applicable to each; like numerals being used to identify the components of each.

Referring now to FIG. 3, the wheel mounting assembly includes a substantially Y-shaped metal bracket 45 comprised of an angularly disposedwing 46 and a substantially horizontally disposedwing 47. Said wings merge in a rolledbody portion 48 through which anaxle 49 carryingwheels 51 is extended. The free end ofangle wing 46 is seated loosely in anaperture 52 in one wall of the related dependingtriangular portion 18 or 28. The substantiallyhorizontal wing 47 is apertured to receive amounting bolt 53 freely therethrough. Carried on thebolt 53, and one on each side ofwing 47, areresilient cushions 54 each having ametal cap 55 seated thereon. The head ofbolt 53 is intended to seat against the bottom one of saidcaps 55 and the free end of the bolt is threaded into the related tappedboss 17 or 27. However, prior to threading of said bolt into its related boss, alock nut 56 is threaded on said bolt so as to lie against theupper cushion cap 55. In assembly, the bolt is threaded firmly into its boss and thelock nut 56 is drawn up tightly against said boss. It should be evident that thebolt 53 may be screwed in as firmly as desired so as to permit variation of the amount of compressive force exerted on the cushions. .Variation in the compressive force applied to the cushion varies the amount of swivel imparted to the wheel mounting assembly. When thenut 56 is drawn up tightly against the boss the assembly is locked securely in its adjusted position. I

Although I have described a preferred embodiment of the invention, in considerable detail, it will be understood that the description thereof is intended to be illustrative, rather than restrictive, as many details of the structure may be modified. or changed without departing from the spirit or scope of the invention. Accordingly, I do not desire to be restricted to the exact construction shown and described.

I claim: v 1. In a roller skate having heel and toe portions ad,- justa-ble toward and away from each other, molded pads of shape-retainingmaterial secured firmly one to each portion, strap-like elements integral with each of said pads, said, pads telescopically embracing the respective heel and toe portions and rivets securing them in place. 1 2 In a roller skate having heel and toe portions adjustable toward and away from each other, molded pads of shape-retaining material secured firmly one to each portion, strap-like elements integral with each of said pads, said pads telescopically embracing the respective heel and toe portions and means securing them in place.
