Cuff pivoting of in-line roller skate
Abstract
An improved cuff hinging structure of an in-line roller skate
includes a plurality of wheels set straight under a chassis, a base
portion mounted on the chassis, and a cuff connected to the boot of
the base portion through pivots on an ankle support cuff, providing
excellent resilience for the cuff and thus enhancing the durability
of the skate.

Claims
What is claimed is:
1. A cuff hinging of an in-line roller skate comprising a plurality
of wheels set straight under a chassis, a base portion with a boot
thereon mounted on said chassis, and a cuff connected to said boot
of said base portion, an ankle support cuff; wherein the
improvement is characterized by said ankle support cuff connects
said cuff with said boot of said base portion whereby providing
excellent resilience for said cuff.
Description
BACKGROUND OF THE INVENTION
[0001] I. Field of the Invention
[0002] This invention relates generally to an improved cuff
pivoting structure of an in-line roller skate and, more
specifically, to an in-line roller skate which has an ankle support
cuff that connects the cuff with the boot of the base portion and
thus provides excellent resilience for the cuff as well as enhances
the durability of the skate.
[0003] II. Description of the Prior Art
[0004] Heretofore, it is known to construct an in-line roller skate
having a base portion mounted upon the chassis and a plurality of
wheels set along a straight line under the chassis.
[0005] An in-line roller skate of such construction typically has a
base portion made of hard materials and enables the ankle to flex
his ankle forward and rearward. As can be seen in FIG. 3, an
in-line roller skate of this kind typically has a plurality of
wheels (b) set straight in a line under a chassis (a), a base
portion (c) mounted on the chassis (a), and a cuff (d) pivotally
connected to the boot of the base portion (c). To put on the skate,
a skater puts his foot into the base portion (c) and ties the cuff
(d) on his lower leg so that his ankle can flex during skating.
[0006] The heretofore known in-line roller skate provides limited
flexibility for the ankle with only one piece of cuff (d) pivotally
attached to the base portion (c). The pivotally structure of this
kind does not allow the skater to flex his ankle forward and
rearward with ease and thus is more likely to result in injuries at
the ankle during skate.
[0007] Further, the base portion (c) and the cuff (d) are connected
with only one pair of trims (e) at the lateral sides that does
provide sufficient rigidity in the lateral direction to endure all
the pressure caused during skating and is to be worn out
easily.
[0008] The present invention improves on the heretofore known
in-line roller skate by providing a cuff hinging structure that
connects the cuff with the base portion. A plurality of wheels is
set in a straight line under the chassis. A base portion is put
upon the chassis. A cuff is connected to the boot of the base
portion through an ankle support cuff. The cuff hinging structure
provides the skate with better resilience and adds durability for
the roller skate.
SUMMARY OF THE INVENTION
[0009] It is therefore a primary object of the invention to provide
an ankle support cuff that forms pivotal connections to the cuff
and the boot of the base portion so as to enhance the resilience of
the cuff and offers durability for the skate.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] The accomplishment of the above-mentioned object of the
present invention will become apparent from the following
description and its accompanying drawings which disclose
illustrative an embodiment of the present invention, and are as
follows:
[0011] FIG. 1 is a lateral view of an in-line roller skate
according to the present invention;
[0012] FIG. 2 is an explosive side view of an in-line roller skate
constructed in accordance with the present invention;
[0013] FIG. 3 is a lateral view of a prior art.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0014] Referring to FIG. 1 and FIG. 2, the present invention
comprises a plurality of wheels 2 set straight in a line under a
chassis 1, a base portion 3 mounted on the chassis 1, and a cuff 4
pivotally connected to the boot 31 of the base portion 3. The cuff
4 and the boot 31 of the base portion 3 are connected through an
ankle support cuff 5, which provides better resilience for the cuff
4.
[0015] Based on the structure mentioned above, the cuff 4 is
indirectly connected to the boot 31 of the base portion 3 through
the ankle support cuff 5, which allows the cuff 4 to flex forward
for about 30 degrees and rearward for about 10 degrees. With this
cuff hinging structure, the skater is able to move his ankle around
freely and with comfort during intensive skating while lowering the
risk of injury of the ankle.
[0016] Furthermore, trims 6a are set on lateral sides of the boot
31 of the base portion 3 and the ankle support cuff 5 for pivotal
connection. Trims 6b are set on both sides of the ankle support
cuff 5 and the cuff 4 for pivotal connection. Four pivots
altogether enhance the strength of the cuff structure to endure the
pressure produced during skating and thus provide the trims 6a, 6b
with considerable rigidity in the lateral direction.
[0017] While only one embodiment of the present invention has been
shown and described, it will be understood that various
modifications and changes could be made thereunto without departing
from the spirit and scope of the invention disclosed.
