a base with parts oi the block extended downwardly to a point a comparatively short distance above a surface upon which the skate is positioned and with straps for securing the skate to a foot or shoe extended upwardly from the block.

The purpose of this invention is to provide a roller skate particularly adapted for beginners wherein stationary parts of the skate are comparatively close to the oor whereby a beginner may tilt the skate to bring a side or heel portion of the block or base against the door to provide a brake.

In the conventional type of roller skate the frame of the skate upon which the rollers are mounted is positioned above the rollers so that it is spaced a considerable distance from the floor and with the parts formed in this manner it is diicuit for a child to bring a fixed part of the skate in contact with the floor, when it is desired to stop or retard the progress oi the skates. With this thought in mind this invention contemplates a roller skate having rollers journaled by shafts in the under surface of a base whereby the base extends downwardly over the rollers and wherein the heel portion thereof is comparatively close to the floor.

The object or" this invention is, therefore, to

rovide means for forming a roller skate for beginners wherein Xed parts of the skate may be moved into Contact with a surface upon which the skate is positioned with comparatively sinall tilting action of the skate.

Another object of the invention is to provide a childs roller skate, particularly adapted for beginners in which rollers thereof may readily be removed and replaced.

.A further object of the invention is to provide a roller skate in which xed mounting elements of rollers thereof are comparatively close to a surface upon which the skate is positioned in which the skate is of a simple and economical construction.

With these and other objects and advantages in View the invention embodies a block having cavities in the under surface, providing a base with rollers mounted on pins positioned the cavities in the under surface of the base and journaled in the base with shafts and with straps extended upwardly from the base for securing the skate to a shoe or the like.

skate (Cl. Z-1L23) Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

Figure 1 is a side elevational View illustrating the beginners skate with the skate shown on a foot as it appears in use.

Fig. 2 is a plan view of the skate.

Fig. 3 is a View looking upwardly toward the under side of the skate.

Fig. 5 is a rear end elevational View of the skate, with parts of the straps broken away.

Figure 6 is a cross section through the skate taken on line 5 6 of Fig. 4.

Figure 7 is a side elevational view similar to that shown in Fig. 1 illustrating a modiiication wherein the skate is formed of plastic.

Figure 8 is a plan view of the skate shown in Fig. 7.

Figure 9 is a view looking upwardly toward the under surface of the skate shown in Fig. 7.

Figure l0 is a longitudinal section taken on line ifi-it of Fig. 9 showing the roller mounting of the skate.

Figure 11 is a cross section through the skate taken on line ll-I i of Fig. 9.

Figure l2 is a detail illustrating the crimped end or^ bosses for holding shafts uponwhich the rollers are mounted in a skirt or flange depending from the body of the skate, said section being taken on line i2-i2 of Fig. 9.

Referring now to the drawings wherein like reference characters denote corresponding parts the improved beginners skate or" this invention includes a block iii providing a base, rollers ll and E2 journaled by pins i3 and iii, respectively in the base, straps i5 and it secured to the under surface of the base with screws il, an elastic toe strap i8, and an ankle strap it.

The block or base l@ is provided with an arcuate forward end 26 and recesses 2| and 22 are provided in the under surface for receiving the rollers il and i2 and notches, as indicated by the numeral 23 are provided at the ends of the recesses for receiving the ends of the pins i3 and iii. Washers 2li are provided at the ends of the rollers to retain the rollers with the ends thereof in spaced relation to the ends of the recesses.

The straps I5 and it, which extend from the upper surface 25 of the block it, at the forward end, extend over the ends of the pins i3 and It, retaining the pins in the notches and' thereby securing the rollers in operative positions in the recesses. The straps extend continuously to the 3 rear end of the block and

ends

26 and 21, of the straps are extended downwardly with

Wedges

28 and 29, respectively whereby the ends of the straps are comparatively close to a door, as indicated by the numeral 30 so that with a slight upward movement of the toe or forward end' of a skate the

ends

21 and 28 of the straps will Contact the floor. The wedges are secured in position with screws 3| that extend through the downwardly extended end of the straps and wedges, and into the block.

The elastic band I8 at the forward end of the skate is secured in position with ends thereof clamped between the straps and under surface of the block, as illustrated in Fig. 6, and it will be understood that the ends of the elastic band may be secured in position by other types of fasteners or other suitable means.

The heel or ankle straps i9 are secured to the end of the block at the rear with keepers or other fastening elements 32 and the upwardly extended sections of the straps are Iheld with a cross strap 38, as shown in Fig. 5. The ends of the sections of the strap I9 are provided with a buckle 34.

In the design illustrated in Figs. '7 to 12 the skate is formed with a plastic body 35 having continuous depending

flanges

36 and 31 at the sides with rollers 38 and 439 mounted on a shaft 40 at the forward end of the skate and rollers 4| and 42 mounted on a shaft 43 at the opposite or rear portionA of the skate.

A tubular spacer 44 is positioned on the shaft 40 between the

rollers

38 and 39 and a similar spacer 45 is positioned on the shaft 43' between the rollers 4l and 42.

As illustrated in Fig. 11 the ends of the shaft are positioned in sockets 46 and 41 in bosses 48 and 49 on the inner surfaces of the

flanges

36 and 31, and, with the shafts in position the lower edges, as indicated by the numerals 50 and 5|, in Fig. 12, are peened inwardly locking the shafts in the sockets. The ends of the shaft 43 are held in similar sockets 53 and 54 in bosses also on the inner surfaces of the

flanges

36 and 31.

In this design the rollers are positioned in a cavity 55 in the under surface of the body 35 and the forward end of the body is provided with an arcuate surface 59 whereas the rear edges of the flanges extend downwardly providing a low point 51 at the heel.

The upper surface of the body is provided with a heel flange 58 in which a strap 59 is positioned and lugs 60 and 6I with openings 62 and 63 therein are positioned at the sides of the forward "f end for retaining a toe strap 64. The strap 84 is provided with a buckle and a buckle similar to the buckle 65 may be provided in the strap 59, as indicated by the numeral 66.

With the lower edges of the depending flanges at the sides of the skate extended downwardly as shown in Figs. '1 and 11 the lateral tilting action of the skate is limited.

It will be understood that modifications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

l. In a roller skate, the combination which comprises a substantially rectangular shaped' block having an arcuate forward end, spaced transversely disposed recesses in the under surface and having notches at the ends of said recesses, pins extended through the recesses with the ends positioned in said notches, rollers mounted on said pins, longitudinally disposed straps secured to the arcuate forward end of the block and to the edges of the block and covering the ends of the pins for securing the pins in the notches with the rollers in the recesses, means securing the straps to the block, said straps having downwardly disposed sections at the rear ends, and straps extended upwardly from the block for securing the skate on a shoe or the like.
