Description
CUSHION FOR IN-LINE SKATE
4 1. FIELD OF INVENTION
The present invention relates to an in-line skate and, more 6 particularly, to a cushion for an in-line skate.
8 2. RELATED PRIOR ART
9 Disclosed in Taiwanese Patent Publication No. 331745 is an in-line skate including a frame 1 and two rolling gears 2. The frame 1 includes 11 two walls 11 each including two pairs of apertures 111. Each of the 12 rolling gears 2 includes two levers 21 and 24, two casters 22 and 25 and a 13 spring 23. Each of the levers 21 and 24 includes an upper section, a 14 lower section and a middle section. A pin 27 is driven into the middle section of the lever 21 through related apertures 111 of the walls 11. A
16 pin 26 is driven in the middle section of the lever 24 through related 17 apertures 111 of the walls 11. The spring 23 is compressed between the 18 upper sections of the levers 21 and 24. The upper sections of the levers 19 21 and 24 can abut the bottom of the frame 1, thus limiting the maximum distance between the levers 21 and 24 and avoiding the escape of the 21 spring 23. However, the lever 21 transfers impact to the frame 1 when 22 the upper section of the former abuts the latter, particularly when the 23 caster 22 bumps a rock. This means poor cushioning.
24 Therefore, the present invention is intended to obviate or at least alleviate the problems encountered in prior art.
2 According to the present invention, an in-line skate includes a frame 3 and two rolling gears. Each of the rolling gears includes two levers 4 pivotally connected to the frame, two casters each attached to related one of the levers, at least one first cushion provided between the levers and 6 two second cushions each provided between related one of the levers and 7 the frame.
8 An advantage of the in-line skate of the present invention is that the 9 second cushions provide excellent cushioning.
Another advantage of the in-line skate of the present invention is that 11 the first cushions prevent the casters from contacting each other, i.e., they 12 prevent the casters from jamming each other.
13 Other advantages and features of the present invention will become 14 apparent from the following description referring to the drawings.
17 The present invention will be described via detailed illustration of 18 embodiments referring to the drawings.
