7 Claims. (Cl. 36-8.3`)

MY invention pertains to a quick mountable and demountable attachment device which may be conveniently applied to the ordinary shoes of children and adults, as well as to the shoes of amateur or professional dancers to enable them to easily do various fancy turns and spins.

It is an object of my invention to provide a shoe spinner attachment device which can be attached to or removed from the ordinary shoes of children or adults quickly after the fashion of ordinary roller skates, and which will enable the wearer to easily perform various turns and fancy spins.`

It is also an object of `my invention to provide a shoe spinner attachment device which is of a simple sturdy construction requiring but few parts.

It is a further object of my invention to provide' a shoe spinner attachment which in a simple construction of few parts provides for a safe frictional tread and holds the shoe of the wearer well above the floor surface.

My invention will be more readily understood and additional objects and advantages thereof will become apparent from reading the following specification in conjunction with the appended drawing, in which:

Fig. 1 is a plan view showing one of my shoe spinner attachment devices;

Fig. 2 is a bottom view thereof;

Fig. 3 is a sectional view taken on line 3-3 on Fig. 1;

Fig. 4 is an enlarged fragmentary sectional view showing how a strap may be attached to the spinner device for attaching the spinner device quickly to the shoe of a wearer; and

Fig. 5 is an enlarged fragmentary sectional view similar to Fig. 4 and showing a different strap attaching arrangement.

Referring more specifically to Figs. 1 through 4, I have illustratively disclosed an embodiment of my improved attachable shoe spinner comprising a shoe plate Il which is adapted to be secured to the sole of a shoe and a iioor plate i3 which supports the wearer upon the floor` surface while turning or spinning. As shown, the shoe plate may be made substantially of a disc shape and of a diameter which is suitable for attachment upon the sole of the wearers shoe. It is to be understood that a pair of these spinner devices is provided, one for each foot. The floor plate I3 may also preferably be of a disc shape and the pivot shaft or pin I5 which pivotally unites these two members is passed centrally therethrough for holding the shoe disc in a con- 2 centrically aligned relation upon the floor disc as the wearer spins thereon.

As may be seen more clearly in Fig. 3, the upper end of the pivot pin or shaft l5 is in the shape of a flat head for holding the shoe plate rotatively upon the floor plate, and the bottom end of this pivot is flared outwardly in a corresponding flared hole in the floor disc, as by peening or riveting it therein, to join these parts in a strong rigidly united structure.

As Figs. 1 and 3 show, the central portion of the shoe disc is conformed to provide a depressed recess il surrounding the upper end of the pivot l5 so that the holding head thereof does not engage the shoe of the wearer. Also this depressed area' il' serves further to hold the shoe disc, and the shoe of the wearer, higher above the surface 22 of the iioor. An annular spacer ring I9 is disposed surrounding the pivot pin I5 and between the shoe disc and the iioor disc to minimize the friction drag therebetween as well as to hold the shoe disc higher above the floor. The spacer ring I9 is preferably made of bronze or other friction reducing material. This provides for freer movement of the person wearing the spinner as well as serving to also reduce the amount of drag or friction between these relatively rotating parts.

Secured to the bottom surface of the floor disc I3 is a fiat pad of yieldable high coeicient of friction material 2| which may be secured thereon as by cementing it to this surface. For this purpose, rubber, synthetic rubber, or various plastic materials are suitable. In addition to providing the wearer with a high friction non-skid tread upon the floor surface, this pad 2| also serves to cushion his movements and serves still further to space the shoe disc higher above the floor surface thereby avoiding frictional engagement between the shoe and the floor.

For convenient attachment to the shoe of the wearer the shoe discs are provided with a strap 23 which may be drawn up from the opposite edges of the disc and buckled over the toes of the shoes to secure the spinner devices upon the sole between the heel and the toe of each shoe, in a manner similar to the attachment of skates for example. Such straps may be attached to the shoe discs Il by providing strap securing apertures 25 therein, as shown in Figs. 1 through 4. Such an attaching strap 23 may be passed over the top of the shoe disc and then threaded down through the strap apertures. Then the ends of the strap are secured together up over the shoe of the wearer. Rubber pads 25 are provided on opposite .sides of the strap on top of the shoe disc to form a fiat surface under the shoe sole. Or the straps may be secured under the edges of the shoe discs, as by a rivet 27 passed through a suitable aperture therein and having a counter-sunk head flush with the upper surface of the disc, as shown in enlarged detail in Fig. 5, pads 26 being omitted.

It is apparent that within the scope of the invention modifications and different arrangements may be made other than herein disclosed, and the present disclosure is illustrative merely, the invention comprehending variations thereof.

What I claim as my invention and desire to secure by Letters Patent of the United States is:

1. A shoe spinner attachment device comprising, a shoe plate, a floor plate, pivot means pivotally mounting said shoe plate upon said floor plate, said shoe plate being conformed to provide a pair of strap securing apertures adjacent opposite edges of the shoe plate, and a spacer ring disposed surrounding said pivot means and between said shoe plate and said floor plate to space these two plates apart and to reduce the friction of said shoe plate rotating upon said iioor plate.

2. A shoe spinner attachment device in accordance with claim 1 and further characterized by said shoe plate being conformed to provide a depressed recess surrounding the upper end of said pivot means, and the upper end of said pivot means being shaped as a at headed shoe plate holding means.

3. A shoe spinner attachment device in accordance with claim l and further characterized by having a pad of yieldable material secured to the bottom of said floor plate for frictional engagement upon a floor surface while also serving to support the shoe plate further above a floor surface.

4. In a shoe spinner attachment device the combination of, a shoe disc adapted to be attached upon the sole of a shoe, said shoe disc being conformed to provide two strap attachment apertures at diametrically spaced points adjacent the periphery of the disc, a fioor disc of a diameter smaller than the distance between said two strap attachment apertures, and centrally disposed pivot means pivotally mounting said shoe disc in a concentrically aligned relation upon said oor disc.

5. A shoe spinner attachment device in accordance with claim l and further characterized by said shoe disc being conformed to provide a depressed recess in the central portion surrounding the upper end of said centrally disposed pivot means, and the upper end of said pivot means being conformed as a at head for holding the shoe'disc upon the iioor disc.

6. A shoe spinner attachment device in accordance with claim 4 and further characterized by having a pad of yieldable high coefficient of friction material on the bottom of said floor disc for engaging upon a fioor surface and serving as a frictional holding means as well as a spacer to support the shoe disc further above the floor surface.

7. A shoe spinner attachment device in accordance with claim 6 and further characterized by having a friction reducing spacer ring disposed surrounding said pivot means between said shoe disc and said iioor disc to minimize the friction of rotation therebetween while also serving to hold the shoe disc higher above a oor surface whereupon said floor disc is supported.
