3 Claims. (Cl. 280-11.31)

This application constitutes a division of our application Serial No. 157,928, filed April 25,1950.

Our invention -relates to a new and useful improvement in a roller skate clamping device adapted for use in clamping against the side edges of the shoe sole of the user of the roller skate. V

It is an object of the present invention to provide in a roller skate, shoe clamping members for clamping against opposite sides of the sole of a shoe and so arranged and constructed that they may be easily spread apart and easily and quickly moved into engagement with the opposite sides of the shoe sole and locked in such engaging position without the use of a key or any other type of a tool.

Another object of the invention is the provision of a clamping mechanism of this class having at opposite sides clamping members movable inwardly and outwardly relatively to each other and provided with a mechanism whereby a proper alignment of these members will always be retained.

Other objects will appear hereinafter.

It is recognized that various modifications and changes may be made in the detail of structure illustrated without departing from the invention and it is intended that the present disclosure shall be considered but the preferred embodiment.

Forming a part of this specification are drawings in which:

Fig. 1 is a fragmentary top plan view of the forward end of a roller skate showing the invention applied,

Fig. 2 is a fragmentary sectional view taken on line 2 2 of Fig. l,

Fig. 3 is a fragmentary sectional view taken on line 3 3 of Fig. 2,

Fig. 4 is a sectional view taken on line 4-4 of Fig. 2,

Fig. 5 is a fragmentary top plan view of the forward end of the invention with parts broken away, parts shown in section and parts removed.

As shown in the drawings the invention comprises a forward or sole supporting plate 21 secured to the bottom of which and depending therefrom is a U-shaped structure 22 which forms a channel member or trough with the opening directed to the bottom of the plate 21. At the forward end of this member 21 is a cross head 23 which is also U-shaped to form a channel or troughlike part and which engages at its open upper edges and is secured to the under surface of the forward end of the plate 21 so as to provide therewith a housing. Slidable in this housing, transversely of the plate 21, are a pair of arms 24 and 25 provided with the upwardly turned sole engaging portions 26, to each of which is secured a strap 28 adapted to be fastened over the toe of the shoe resting upon the plate 21. Formed in the plate or arm 25 is a slot 29 having teeth 30 on one side or edge meshing with the gear 31 which is rotatably mounted in the channel 23 or housing formed thereby. As shown in Fig. 4, this gear 31 is integral with a larger pinion 32 from which projects a stud 33 engaging in the opening 34 formed in the member 23.

A stud 35 projects from the gear 31 and engages in an opening 36 formed in the plate 21. A slot 37 is formed inthe plate or arm 24 and has teeth 38 on one side meshing with the gear 31. The construction is such that the arms 24 and 25 may be moved outwardly or inwardly of the edges of the plate 21. As one of the members 24 or 25 is pulled outwardly, the gear 31 will rotate to force the other outwardly and likewise when one of the plates 24 ori 25 is moved inwardly, the other one will also move inwardly because of this pinion rack bar construction.

Swingably mounted in the housing in which the gears are mounted is a pawl 39 normally held by a spring 40 in engagement with the ratchet teeth formed on the gear 32 so as to prevent a rotation of the gear 32 in one direction. Extending into the housing in which the gears are mounted and accessible from the exterior thereof is a lever 41 having a nose 42 and provided with a boss 43. This lever 41 extends through a slot 44 formed in the wall 45 of the housing. The arrangement is such that when the lever 41 is rocked in one direction it will force the pawl 39 out of engagement with the ratchet teeth of the gear 32 so that the gear 32 may freely rotate. When the nose 42 is in this position the sole engaging clips or angularly turned portions 26 may be spread apart so that the shoe of the user of the skate may be placed therebetween. When this has been accomplished the lever 41 would be rocked to permit the pawl 39 to engage the ratchet teeth and the members 26 may then be moved inwardly into close engagement with the opposite sides of a sole of a shoe. In this movement the gear 32 would be rotating and the pawl 39 would be riding over the ratchet teeth of the gear 32 so that the members 26 are automatically secured in their inwardly moved positions and prevented from sliding apart. In this way these members 26 may be moved into tightly clamping relation to the edge of the sole and the use of keys or the like is avoided.

What we claim is:

l. In a roller skate of the class described, a supporting body for supporting the shoe of the user with the sole of the shoe directed toward the forward end of the body; a pair of arms extending transversely of said body, and moveable inwardly and outwardly of the opposite edges thereof adjacent the forward end thereof; an engagement portion carried by each of said arms on its outer end, for, upon inward movement of said arms relatively to said body, engaging the sole of the shoe adjacent the forward Iend thereof; teeth formed on each of said arms adjacent the inner end thereof; a pinion rotatably mounted on said body for meshing with the teeth on said arms, the teeth on one of said arms meshing with said pinion at one side and the teeth on the other of said arms meshing with the pinion at the diametrically opposite side; a gear fxedly mounted on said pinion in axial alignment therewith; a rockable pawl on said body and engageable at its free end with the teeth of said gear; a spring for normally maintaining said pawl in engagement with the teeth of this gear; and a rockable cam on said body rockable into a position for moving said pawl out of engagement with the teeth of said gear and retaining said pawl in such moved position.

2. In a roller skate of the class described, a supporting body for supporting the shoe of the user with the sole of the shoe directed toward the forward end of the body; a housing mounted on the under surface of said body; a pair of arms extended transversely of said body and extending at one of their ends into said housing and movable inwardly and outwardly of opposite edges of said body adjacent the forward end thereof; an engagement portion carried by each of said arms for, upon inward movement of said arms relatively to said body, engaging the sole of the shoe adjacent the forward end thereof; teeth formed on said arms adjacent the inner end thereof; a pinion rotatably mounted in said housing for meshing with the teeth of said arms, the teeth on one of said arms meshing with said pinion at one side and the teeth on the other of said arms meshing with the pinion at the diametrically opposite side; a gear fixedly mounted on said pinion in axial alignment therewith; a pawl rockably mounted at one of its ends in said housing and engageable at its opposite end with the teeth of said gear;` a spring normally urging said opposite end of said pawl into engagement with the teeth of said gear; a rockable cam projected into said housing and engageable with said pawl for, upon rocking in one direction, moving said pawl and retaining the same out of engagement with the teeth of said gear.
