Abstract: A roller skating device combining advantages of conventional roller and in-line skates, and skateboards is presented. A “boot” (as defined herein) for snugly encasing a selected foot of a user has an undercarriage, i.e. a frame, connected to it in fixed relation. A rigid member having a planar top is affixed to the undercarriage, preferably behind the heel of the boot, for engaging the free foot of the user, i.e., the foot not wearing this invention. A plurality of rollers, connected to the undercarriage, rollingly support the undercarriage, and all connected to it, on a skatable surface. The free foot engages the planar top by resting on and, at selected times, pressing forcefully against the planar top to help control the device during operation. Two exemplary embodiments are described herein: an embodiment having a rectangular pattern of rollers and an embodiment having a single line of rollers.

Abstract: A frame for a sports article, especially a frame for a roller skate, including a front upper portion provided to receive the front portion of a boot, and a rear upper portion provided to receive the rear portion of a boot. The front upper portion and the rear upper portion are part of the same planar upper surface. The frame further includes two cylindrical holes provided to receive two fixing elements, the holes extending in the longitudinal plane of the frame and their respective axes being spaced from one another by a value E of between about 164 mm and 170 mm, more particularly equal to about 167 mm. Moreover, a substantially cylindrical cavity centered on the axis of the cylindrical hole is provided in the upper surface. The invention is also directed to a line of boots for a roller skate and to a line of frames therefor.

Abstract: A skate includes a base, an adjusting member, and a boot including a front portion and a rear portion. The front portion is provided on a front portion of an upper side of the base.

When the adjusting member is pushed, the rear portion is adjustable along a longitudinal direction of the base.

Abstract: An easily adjusted skateboard shoe comprises a front seat, a rear seat and a buckle structure for connecting the front seat and the rear seat. The buckle structure is formed by a round lower cover, a buckle, and a teeth bank. An upper side of the lower cover has a confining seat and the confining seat has guide grooves at two sides thereof. Thereby, the buckle moves straightly along the guide grooves of the lower cover. One inner end of the buckle has an engaging teeth which protrudes downwards and extends inwards so that the engaging teeth is exactly engaged to the teeth bank at a lower end of the front seat. The user can press the buckle from a lateral side of the skateboard shoe so that the engaging teeth of the buckle separates from the teeth bank; and thus the size of the skateboard shoe is adjusted.
