The upstanding ear l8 of such plate may be apertured at IQ for the reception of a conventional tie strap (not 4 The present improvements relate to a compact, allfmetal skate of simple design particularly in tended for juvenile use, and one which may readily be ‘converted into either an ice skate or a roller skate and be pro?tably marketedat a shown). ‘ ‘V ‘ Intermediate its ends, the. runner Iiipmay be equipped with a substantially flat sole plate 20 as mounted upon the toe cup 2| having its base ?xedly riveted to the ‘runner at 22. Said sole moderate retail price. The novel structural fea tures herein embodied afford a rigid cross~sec tionally bifurcated-runner blade for ice skating and detachablyl centeredin the mouthed crotch thereof, is a unitary roller mounting chassis of the underslung type. ofthese components is such as. to provide for a plate may be provided with one or more sunken strap receiving‘ lugs such as 23 or with equivalent shoe engaging means. ‘ The forward end of such sole platemay ‘have a stabilizing strut 2d struck therefrom and cleated to the runner crown as in Fig.3. Both of my sole and heelplates‘are a trim appearance and require comparatively few 15 purposely elevated above the level of the runner socket and arranged to present a substantially principal partsv ‘adapted to‘ be economically flat foot rest devoid ofupstanding ridges.

When detached, my unused chassis may several structural, elements; that collectively be independently stowed without chassis dis sturdy roller skatehassembly that shall present 20 . memberment.‘ The object of my invention is to devise a re constitute the ice skate component ofmy assem bly and as such may" be independently utilized fined convertible skate of the indicatedcharacter in ‘a conventional manner. In order‘ toprovide in which a cross-sectionally socketed runner for a multipurposeskatdqmy improved chassis blade may be demountably seated upon a unitary has been adapted; to be securely coupled to the aforesaid component. To this end, I provide for roller-mounting chassis and permitting the 25 a stamped sheet metal understructure or unitary bodily detachment of such chassisas an assem roller‘ chassis 30 having an inverted troughlike blediiunit. Embodied herein are also structural cross-sectional pro?le. Such framework prefer re?nementspertinent to a roller skate assembly ably‘comprises a stepped region de?ned by the of the non-separable‘chassis. type. ‘ I Reference is ‘had to the accompanying one 30 parallelly aligned flat flank ?anges 3| and‘ 32 sheet of drawings which exempli?es alpreferred embodiment of my skate, and in whichr Fig. 1 represents a top view of;such convertible skate assembly; and Fig. 2 is an elevational side view thereof with my chassis attached for roller 35 skating purposes.

Referring more explicitly‘to these disclosures, theice' skate component thereof may comprise a semitubular, . cross-sectionally dished or socketed runner iii of sheet metal shaped to pro vide for divergent double blades H ‘and I2 that respectively provide for the sharpened runner edges HA and 12A as indicated in Fig. 5. The apex or crown region of. such U-shaped runner which may be integrally spanned by the saddle ridge 33 extending longitudinally of the chassis length as shown. Said centralized ridge maybe shaped to snugly nest interiorly beneath the socketed runner in the underslung fashion cross sectionally depicted in Fig. 5. As will be obvious, the dished runner l0 and the nested saddle ridge 33 may in certain instances be integrally affixed to support the heel and sole plates l6 and 2D thereon. } i p ‘The rear ridge region may be slotted in registry with the runner slot l5, the bolt ‘I? being kept sufficiently long to clampingly enter therethrough. Similar supplement ry bolts or‘dowels such as "A and NB serve‘ to‘ additionally retain the saddle ridge 33 against displacement when‘assem bled in place as a convertible skate.

The. rear end region of the runner purposely disposed to leave a protectiveclearance crown may be slotted at l5 and have a heel plate It that is propped bythe cup 25 and adjustably 5.5 gap 34 between the straddling sharpened edges ‘ erected along‘ said crown by’ the clamping bolt 2,410,609 i i and 3|I2and and32.their respective underlying ?ank ?anges Each outer edge of such ?ank 10 W 20 ?anges 3i and 32~as shown; ‘ _ > As a further re?nement, the ‘toe end Qf my 30 35 41 roller skate ‘to impart a assembly; assembly ‘ Comprising 'a' stamped elongated ‘sheet metal chassis frame ) Work forégéihg preferred exempli?‘c‘a'tibn ‘will, it ‘ ' inverted éross-s'ectionally trough-like pro?le shaped to provide for cornplei 'eved, v'Inake ‘evident ‘to those skilled this art, further advantages inherent in my skate im t'ofo'z‘e described and more partie1'11ar-Iybha'racter~ 60 65 said bib portiqn and 'rid'ge. ‘ 7.
