ADJUSTABLE TOE FASTENER FOR ROLLER SKATES Filed Jan. 10, 1964 2 Sheets-Sheet 2 INVENTORS ALLN L. BROWNLEE SIDNEY K. SMART BY MW wind Mmny-S United States Patent 3,279,808 ADJUSTABLE TOE FASTENER FOR ROLLER SKATES Allen L. Brownlee, Westfield, and Sidney K. Smart, Blandford, Mass., assignors to Globe Skate Corporation,

Manitowoc, Wis., a corporation of Wisconsin Filed Jan. 10, 1964, Ser. No. 336,965 9 Claims. (Cl. 280-1131) This invention relates to roller skates and the like and more particularly to an adjustable shoe fastener assembly for the front sole plate of such skates.

An object of the invention is to provide a quickly adjustable shoe or toe plate assembly for fastening the toe of a users shoe on the skate. The fastener assembly is adapted to fit and accommodate a wide range of shoe sizes and to be easily fastened and unfastened without the use of separate tools such as a conventional skate key.

The fastener assembly of this invention utilizes a spring action for locking the shoe holding members in a desired gripping position, the users shoe tending normally to wedge the holding members toward a locked condition so that under ordinary circumstances only deliberate manipulation of the holders against the spring will result in releasing the fasteners for readjustment of the holding members.

A more specific object of the invention is to provide a fastener construction in which a simple inwardly directed push on the holding members at each side of the sole plate will cause the members to automatically shift into holding position against the shoe without elaborate adjustment. In releasing the members a simple rearwardly directed push and outward pulling action only is required.

Insofar as is known the nearest prior art is that shown by 1863 Patent No. 37,305. In this prior construction a pair of holding members are held in place by spring means but these members are released to fasten or unfasten the skate only by manually holding the spring out of contact with the shoe engaging members so that the latter can be moved as desired.

The above and other structural and functional advantages of the present invention will be apparent from the following disclosure of invention as shown by the accompanying drawings in which:

FIG. 1 is a perspective view of a roller skate embody ing the invention;

FIG. 2 is a view of the underside of the sole or toe plate of FIG. 1 showing a bracket for holding the inner ends of the fastener members and the spring means associated therewith;

FIG. 3 is an enlarged fragmentary view of the assembly of FIG. 2 with portions cut away to illustrate details of construction;

FIG. 4 is a view similar to FIG. 3 to illustrate the operation of the device;

FIG. 5 is a view similar to FIGS. 2 and 3 showing a fastener at its outermost position;

FIG. 6 is a section on line 66 of FIG. 2; and

FIG. 7 is a section on line 7-7 of FIG. 2.

In FIG. 1 a roller skate is shown which may be generally of conventional construction having a rear or heel plate 2 with guard 4, ankle strap 6, wheel frame 8, and wheels 10. A front or sole plate is indicated at 12 supported on a wheel frame 14 with wheels 16. The heel plate 2 is part of a rear skate frame which extends forwardly in the form of a tongue 18 (FIG. 2) underlying a front skate frame 19 of which the toe plate 12 is a part. A longitudinal slot 21 is formed in tongue 18 through which a fastener bolt 23 (FIG. 1) on frame 19 passes so that the front and rear frames are telescopically joined and the length of the platform is adjustable to accommodate various shoe lengths as will be readily understood.

The fastener assembly for embracing the front part of the wearers shoe is preferably at the forward portion of the sole plate 12 where the flanged sides of the Plate converge toward the tip end thereof as shown by FIG. 2. As seen from FIG. 1 and FIG. 2 the outer part of each fastener member, generally indicated by the numeral 20, is provided by an upwardly and inwardly angled arched shoe engaging portion 22 which is adapted to snugly embrace the toe of the shoe at each side. The inner part of the fasteners support the portion 22 in any position of adjustment and as shown in the drawings this inner part is an inwardly directed flat bar or blade 24 passing through a slotted portion of the plate flange and slidably fitted in a bracket 26 fixed to the underside of the sole plate 12.

Each blade 24 is formed with a rack or series of teeth 28 projecting forwardly of the front edge of the blade along an inner end portion thereof, the teeth being adapted to engage the forward edge of the slot in the flange to retain the fastener against transverse movement. The bracket 26 together with a spring 30 mounted on the bracket and engaging the blade serves to yieldably maintain an operative holding blade position as will be described.

.The sole plate 12 as shown is provided with the downwardly extending flanged skirt at 32. At opposite sides of the plate the flange portions are provided with the oppositely positioned slots 34 through which the blade supports 24 pass. Bracket 26 is transversely positioned between slots 34, being U-shaped (FIG. 7) with flanged front and rear walls 36 and a connecting wall 38. The walls 36 are flanged for attachment to the underside of the sole plate as by spot welding. Thus an open ended channel bracket to receive the ends of the blades is formed with its ends being spaced from the side flanges 32 as shown. It will be noted (FIG. 6) that the slots 34 are vertically offset so that the blades will be horizontally disposed and in overlapping relation to each other within the bracket.

As best shown by FIG. 3 the teeth 28 of each blade lie along an inner end portion only, the crown of the teeth thus being forwardly offset from the front edge of the outer end portion of the blade. Along the back edge of the blade, an inner end portion is recessed with relation to an outer end portion, the recess indicated at 40 being in substantially coextensive opposed relation to the toothed rack portion. The outer end of the recess terminates in an abutment 42 and thus the inner portion is forward-1y oflset relative to the outer back edge.

The spring means of the assembly is conveniently mounted on bracket 26 and is formed as a spring wire element 30 retained by eared tabs or hooks struck from the metal of the connecting wall 38 of the bracket. A central tab or ear 46 faces forwardly and end tabs 43 are faced rearwardly (FIG. 7). The wire 30 has a central loop (FIG. 2) caught under tab 46 and at each side the wire extends under a rearwardly facing tab 48 adjacent each open end of the bracket. The wire is bent upwardly at each tip end 50 to engage the back edge of the blade at its recessed portion 40 adjacent the edge of the toe plate. The tip end of the wire is thus substantially in a rearwardly aligned position relative to the forward edge of slot 34 of the flange. Each side of the wire spring is stressed forwardly and the tip engaged against the recessed back side of the blade.

Accordingly the spring urges the blades forwardly for engaging one of the teeth against the inner wall of the flange at the forward edge of a slot 34 as seen in FIG. 3. In this position it will also be noted that the blade is swung against the rear wall 36 of the bracket to lock the fastener in this position of adjustment. Furthermore it will be appreciated that when a wearers shoe is embraced by the outer arched portion of the fastener the tendency of the wearer is to exert a forward thrust against the arched portion and thus maintain the fastener in the desired position of engagement.

From FIG. 4 it will be seen that the fastener is released by -a rearwardly directed push and an outward pulling action so that the blade can be slidably moved to any of the several positions of adjustment afforded by the teeth. As shown the rearward push against the spring tip 50 carries the crown of the teeth away from the forward edge of slot 34 and the blade will pivotally move to carry its outer end forwardly against the front wall 36 of the bracket. The walls 36 thus serve as a guide and to limit pivotal motion of the blade-s.

In FIG. 5 the fastener is shown in its. outermost position of adjustment. Here the top of the spring catches the abutment 42 of the recessed inner portion to prevent further outward movement. By manually pressing the spring clear of the abutment, the blade can be separated from the assembly if desired. The extreme outer end of the blade is angled at its rear corner edge for easy assembly of the blade by simply pushing inwardly to deflect the spring tip 50 when the blade is to be inserted. This is shown by the dotted line representation in FIG. 5.

It is also to be noted that the edge of each tooth at its inboard side is formed with a less acute angle than at the outboard side. The sharper angle of the latter is to insure a firm holding pressure against the inner forward edge portion of the slot 34 while the inclined inboard edge enables the blade to slide past the edge easily when being pushed inwardly. Thus the blade merely clicks past the edge by applying simple inward pressure until the outer arched portion is snug against the shoe in which position the fastener will automatically be locked in operative holding condition.

Having thus described the invention, what is claimed as novel and desired to be secured by Letters Patent of the United States is:

1. In combination a sole plate and adjustable shoe fastener assembly for roller skates and the like comprising a sole plate having downwardly extending flanges with portions providing slots at opposite sides of the plate, a fastener member mounted on each side of the plate having an outer upwardly and inwardly angled shoe engaging portion and an inwardly directed adjustable blade support passing through the slot of the flange and under the plate, each blade support having a front edge with an inner end portion of said edge provided with a rack of teeth projecting therefrom in forwardly offset relation to the outer end portion of the front edge, and a back edge with an inner end portion recessed in forwardly offset relation to the back edge of the outer end portion, the said recessed portion forming an abutment at the end of the inner portion, blade guide means at the underside of said sole plate inwardly spaced at each end from said flanges and including front and back wall members receiving said blade supports, said wall members limiting pivotal motion of said supports, spring means slidably engaging the recessed back edge portion of each said blade support in substantially rearwardly aligned position relative to the forward edge of each said flange slot and yieldably engaging teeth of said rack with said slotted flanged portion, said supports when swung against said spring means disengaging said teeth, and when in said latter position being movable transversely of said sole plate for adjusting said 'shoe engaging portions.
