Description

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The invention relates to an in-skate having a pliable boot and a base frame, and more particularly, to an in-line skate having a pliable boot and a base frame, in which flanges disposed with corresponding through holes and lugs are provided for fitting the tracking system and the shoe body thereof into a lower protection base thereof so as to form a flexible body capable of dispersing the stress produced by bouncing or turning at high speeds.

(b) Description of the Prior Art

FIG. 1 shows a conventional elevational view of a prior art. Because of the flourishing of in-line skates during the recent years, various brands of in-line skates have become available successively. However, there are no significant differences apart from the styles thereof with respect to the prior in-line skates. Referring to FIG. 1, the structure of a conventional in-line skate comprises a

shoe body

1 consisted of a boot 12 fitted into an attachment frame 17, a tracking system 15 attached to the bottom of the attachment frame 17 by means of two attachment members 18 using rivets 16, and a plurality of wheels 153 pivotally disposed at the bottom of the tracking system 15 for sliding movements. Nevertheless, the design of such prior art has not taken in the consideration that the third wheel (A) and the fourth wheel (B) thereof bear the largest stress from withstanding most of the body weight. As a result, during turning or braking at a high speed or even sudden landing after jumping, the attachment members 18 connecting the attachment frame 17 and the tracking system 15 often break on the spot (as indicated by symbol C in FIG. 1), further causing damages and irreversible body injuries. Such shortcomings have long since bothered and perplexed industrialists as well as consumers. Therefore, it is a vital task to provide an in-skate having a pliable boot and a base frame having enhanced practical values.

SUMMARY OF THE INVENTION

Therefore, an object of the invention is to provide an in-line skate whose tracking system and attachment frame are free from breakage caused stress produced during turning or braking at a high speed or sudden landing by dispersing the produced stress thereof to the various members of the invention, thereby obtaining an-line skate having more durable members as well as better safety.

In order to accomplish the aforesaid object of the invention, the structure in accordance with the invention comprises a lower seat having a flange provided at the bottom of a shoe body, a base frame provided below the lower seat for fitting the shoe body and having lugs formed by downwardly extending the front through holes with corresponding through holes for the flanges to penetrate through, a lower protective seat provided at the two sides of the rear through holes of the base frame for fitting the shoe body and attaching to a protective boot above. The aforesaid members are then combined into a flexible body using rivets so that stress produced is immediately dispersed, thus avoiding breakage of the members thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The structure in accordance to the invention shall be described with the accompanying drawings hereunder. [0012]
Referring to FIGS. 2, 3 and [0013] 4 showing an elevational view, an exploded elevational view and a side view according to the invention, respectively, the invention comprises a shoe body, a base frame, a tracking system, a lower protection seat and a protective boot. Wherein, below the shoe body 12 is provided with a lower seat 121 further provided with U-shaped flanges 122 that are wider at the top and narrower at the bottom at both the front and rear sides thereof for rivets 16 to penetrate through, and at the flanges 122 provided at the front and rear sides are disposed with through holes 121. The two U-shaped flanges 122 above serve as illustrative purposes of the embodiment according to the invention, and the number of the flanges 122 is not limited but may be two or more. At the bottom of the lower seat 121 is provided with a base frame 13 for fitting the shoe body 12 and a tracking system 15. The base frame 13 is provided with through holes 132 at corresponding positions thereof for penetrating through the flanges 122 of the aforesaid lower seat 121. The front through holes 132 extended downward are further disposed with lugs 131 having through holes 1311. Referring to section B in FIG. 3 showing a partial enlarged view, the base frame 13 is for fitting the tracking system 15, and a tracking frame 151 is provided with wheels 153 for sliding movements. In order to fasten the lugs 131 at the sides to the tracking system 15 by inserting through the through holes 132 at the front of the base frame 13, and to fasten the flanges 122 at the rear of the lower seat 121 of the shoe body 12 and a protection seat 14 below the shoe body 12, at positions of the tracking frame 151 of the tracking system 15 corresponding to the lugs 131 are provided with rivets 16 and through holes 152 for inserting screws.
FIGS. 4 and 5 show a side view in accordance with the invention and a sectional view of FIG. 4 along [0014] 5-5, respectively. During the assembly thereof, the base frame 13 is fitted into the lower seat 121 of the shoe body 12. For that the base frame 13 is provided with through holes 132 at the front and rear thereof, respectively, and the through holes 132 at the sides of the base frame 13 then enable the flanges 122 of the lower seat 121 to extend downward. In addition, also because the rear of the base frame 13 resembles the design of an inverted hood, the heel of the shoe body 12 is accommodated therein. In the meantime, the lugs 131 extended at the sides of the front through holes 132 enclose the outer edge of the tracking frame 151 of the tracking system 15, and therefore the front flanges 122 are fitted into the interior of the tracking frame 151 provided with through holes 152 of the tracking system 15, and further form a flexible body by inserting and fastening with rivets 16 or screws. Moreover, the flanges 122 at the lower seat 121 protruing through the rear through holes 132 of the base frame 13 are fitted into the through holes 152 of the tracking frame 151. In order to have the lower protection seat 14 provided with through holes 141 enclose the outer edge of the tracking frame 151 simultaneously, openings 142 are disposed at the center of the lower protection seat 14, so as to further directly fasten the flanges 122 at the rear of the lower seat 121 to the rear through holes 152 of the tracking frame 151 of the tracking system 15 via the base frame 13 and the lower protection seat 14, thus forming a flexible body. In addition, the upper portion of the invention is provided with a protective boot 11 for protection purposes. It is illustrated from the above that, in accordance with the invention, the shoe body 12 is fastened to the lower seat 121, and the lower seat 121 is further combined with the base frame 13 through the flanges 122 and the front lugs 131, and the tracking system 15 through the front through holes 152. Not only the heel of shoe body 12 is enclosed by the rear base frame 13, the lower protection seat 14 is also fastened to the tracking frame 151 using the flanges 122 through the openings 142 and the rear through holes 152. The through holes 152 at the sides of the tracking system 15 are enclosed at the lower sides of the lower protection seat 14, so as to form two flexible bodies using rivets 16 or screws. As a result, stress produced from progressing, turning or braking at high speeds, or even sudden landing, is effectively dispersed to the various members of the invention, thereby preventing breakage causing dangers and accidents as well as lengthening the lifespan of the members.
It is of course to be understood that the embodiment described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
