Detachable skate frame

Abstract

A skate includes an inverted groove-shaped base secured to a boot and including front and rear pins; an elongated frame including front and rear sets of a transverse inner groove and a transverse open groove communicating with the transverse inner groove, and a threaded hole on the transverse open groove of the front set wherein either pin is disposed in the transverse inner groove and the elongated frame abuts an underside of the base; and a locking device including a spring biased block member disposed in the transverse open groove of the front set and having two projections at two ends respectively, a screw driven through a positioning member into the threaded hole to fasten the positioning member in the transverse open groove of the front set so that the block member abuts the front pin to block same in an assembled state.

Claims

1. A skate, comprising: a boot; an inverted groove-shaped base secured to the boot and including front and rear pins; an elongated frame including front and rear sets of a transverse inner groove and a transverse open groove communicating with the transverse inner groove, and a threaded hole on the transverse open groove of the front set wherein either the front pin or the rear pin is disposed in the transverse inner groove and the elongated frame abuts an underside of the base; ground engaging means secured to the elongated frame; and a locking device including a spring biased block member disposed in the transverse open groove of the front set and having two projections at two ends respectively, the projections extending out of two ends of the transverse open groove of the front set respectively, a positioning member partially disposed on the spring biased block member, and a threaded fastener driven through the positioning member into the threaded hole to fasten the positioning member in the transverse open groove of the front set so that the block member abuts the front pin to block same in an assembled state.

2. The skate of claim 1, wherein the ground engaging means is an ice blade.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Referring to FIGS. 1 to 4, an ice skate in accordance with a first preferred embodiment of the invention comprises a boot 10, a base 20, a frame 30, an ice blade 40 and a locking device 50 as discussed in detail below.

[0013] The inverted groove-shaped base 20 is secured to the boot 10 and includes two pins 21. The frame 30 includes front and rear sets of a transverse inner groove 311 and a transverse open groove 312 communicating with the transverse inner groove 311. Either pin 21 is disposed in the transverse inner groove 311 after disposing through two sides of the base 20 and passing through the transverse open groove 312. Thus, the frame 30 abuts a bottom of a top of the base 20. The ice blade 40 is secured to a bottom of the frame 30.

[0014] The locking device 50 as the subject of the invention is disposed in the transverse open groove 312 of the front set and includes a block member 51 disposed in the transverse open groove 312 of the front set and having two projections 511 at two ends respectively, the projections 511 extending out of two ends of the transverse open groove 312 of the front set respectively, two torsion springs 52 having a bottom urging against a bottom of the transverse open groove 312 of the front set and a top urging against the block member 51, a positioning member 53, and a screw 54 driven through the positioning member 53 into a threaded hole 32 of the frame 30 to fasten the positioning member 53 in the transverse open groove 312 of the front set. Thus, the block member 51 abuts the front pin 21 to block same in an assembled state.

[0015] A wearer may remove the rear pin 21 from the transverse inner groove 311 of the rear set and remove the rear pin 21 from the transverse open groove 312 of the rear set sequentially. Next, the wearer may lift a rear portion of the base 20 by pivoting about the front pin 21 until the block member 51 is sufficiently exposed. Next, the wearer may use the fingers to press the projections 511 with the torsion springs 52 being compressed until the transverse inner groove 311 of the front set is not blocked by the block member 51. Further, the wearer may remove the front pin 21 from the transverse inner groove 311 of the front set and remove the front pin 21 from the transverse open groove 312 of the front set sequentially. As a result, the base 20 and the frame 30 are detached.

[0016] Steps reverse to the above steps can assemble the base 20 and the frame 30.

[0017] Referring to FIG. 5, an inline skate in accordance with a second preferred embodiment of the invention is shown. The characteristics of the second preferred embodiment are substantially the same as that of the first preferred embodiment except the following: the ice blade 40 is replaced by four wheels 41 arranged inline.

[0018] Referring to FIG. 6, a roller skate in accordance with a third preferred embodiment of the invention is shown. The characteristics of the third preferred embodiment are substantially the same as that of the first preferred embodiment except the following: the ice blade 40 is replaced by two front wheels 42 arranged in a front, transverse, straight line and two rear wheels 42 arranged in a rear, transverse, straight line.

[0019] While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
