ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a wheel seat assembly for a roller skate, and more particularly to a wheel seat assembly for a roller skate having a roller seat that can be folded or pulled out.
2. Description of the Related Prior Art
The closest prior art of which the applicant is aware is disclosed in his U.S. patent application Ser. No. 09/325,379, filed on Jun. 4, 1999, entitled “Wheel Assembly for a Roller Skate”.
In this application, the pivotal seat
340
is fixed to a bottom plate
412
which is a single plate with a proper hardness and is fixed to a sole
403
. Therefore, for satisfying the requirements of shoes of various types and sizes, the manufacturing factory needs to produce bottom plates
412
of different sizes. In addition, when the roller skate is put on to function as one of a pair of walking shoes, the bottom plate
412
is a hard plate and cannot be bent so that the wearer easily feels uncomfortable during walking. Further, the pivotal seat
340
is fixed to the bottom plate by bolts
415
, thereby causing inconvenience and difficulty and also consuming a lot of time during the assembling and dismantling process. Further, when the wheel seat
330
is pivoted through a determined angle, the stop
351
of the stop means
350
is rested on the wall of the pivotal seat
340
, thereby preventing the wheel seat
330
from proceeding its pivotal action continuously so as to prevent the wheel seat
330
from being folded, thereby preventing causing danger due to a folding action. However, the stop
351
is only pressed by the elastic member
352
without providing the positioning and fixing effects on the stop
351
so that the stop
351
tends to slide to fold the wheel seat
330
during operation of the roller skate, thereby causing danger to the skater.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a wheel seat assembly of a roller skate, wherein the roller seat of the roller skate, according to the practice requirements in use, can be adapted to pull out the rollers to function as a roller skate, or fold the rollers when not in use, and the roller seat can be actually positioned when in use or not in use.
The secondary objective of the present invention is to provide a wheel seat assembly of a roller skate, wherein the roller seat of the roller skate can be conveniently fixed on the casing of the sole body so that the roller skate is easily worked, and the roller skate can be adapted to provide a comfortable sensation to the wearer during travel.
The wheel seat assembly of a roller skate of the present invention includes a sole body fixed on the bottom of a shoe. The sole body is provided with receiving chambers for securing casings therein. The casing defines an axial hole and at least two positioning holes. A roller seat is pivotally mounted in the casing by a pivot member. The pivot member is fitted with a catch member and an elastic member. The catch member may be selectively locked into one of the positioning holes of the casing by an urging action of the elastic member. The roller seat has a roller rotatably mounted therein by a rotation shaft.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
