1. Field of the Invention
This invention is related to a combined sports shoe and roller skate and in particular to one provided at the bottom with a collapsible roller assembly which can be controlled to convert a sports shoe into a roller skate as desired.
2. Description of the Prior Art
Referring to
FIG. 1
, the conventional combined sports shoe and roller skate comprises a body
10
having a bottom formed with a chamber
14
. A bottom plate
11
which has a plurality of holes
12
is arranged inside the body
10
. A roller seat
20
is fitted inside the chamber
14
of the body
10
and fixedly mounted on the bottom of the bottom plate
11
by screws
13
. The roller seat
20
includes a base
21
and a moveable bracket
22
. The base
21
has two lugs each having a hole
211
through which a pin
23
is passed for pivotally coupling the bracket
22
. The bracket
22
includes a rod
221
for fixing an end of a spring
26
. The other end of the spring
26
is fixedly connected with the base
21
. A roller
25
is pivotally connected with the moveable bracket
22
by a bolt
24
, and the roller
25
can be turned out of the chamber
14
to convert the shoe into a roller skate, or turned into the chamber
14
to convert the roller skate into a sports shoe as desired. However, the user must use his or her fingers to turn roller
25
into or out of the chamber
14
of the bottom of the shoe thereby causing much inconvenience in use and making the fingers very dirty.
Therefore, it is an object of the present invention to provide a combined sports shoe and roller skate which can obviate and mitigate the above-mentioned drawbacks.
SUMMARY OF THE INVENTION
This invention is related to an improvement in the structure of a combined sports shoe and roller skate.
It is the primary object of the present invention to provide a combined sports shoe and roller skate which utilizes a control button to control a roller assembly to turn out or into a chamber at the bottom of the shoe so as to convert the sports shoe into a roller skate or convert the roller skate into a sports shoe as desired.
It is another object of the present invention to provide a combined sports shoe and roller skate which utilizes a linking rod to control front arms and rear arms to open or collapse the rollers.
According to a preferred embodiment of the present invention, a combined sports shoe and roller skate includes a sole having a chamber in which is mounted a collapsible roller assembly, wherein the roller assembly has a seat pivotally connected with linking rods, positioning rods, rear arms, front arms, rollers and torsion spring at two sides and a control mechanism is mounted on the seat and composed of a locking bolt, an axle, a pawl, a torsion spring, a tension spring and a pushbutton, whereby the sports shoe can be converted into a roller skate as desired simply by depressing a pushbutton and the roller skate can be also converted into a sports shoe by collapsing the roller assembly into a chamber at the bottom of the sole.
Other objects and merits and advantages of the present invention will become apparent when the following detailed description is read in conjunction with the accompanying drawings.
