ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a buckle device that has a protrusion extending from a bottom of a lever member and a base on boots has a recess to receive the protrusion when the buckle device is in secure position.
BACKGROUND OF THE INVENTION
A conventional buckle device for skates is disclosed in FIG.
1
and generally includes a base
13
fixedly connected on a boot
101
and the base
13
has two lugs
130
extending from two sides thereof. A U-shaped lever member
12
is pivotably connected between the two lugs
130
by its two legs by a pin
120
. A strap head
10
is pivotably connected between the two legs of the lever member
12
by another pin
111
. A strap
11
with teeth extends from the strap head
10
and is able to be engaged with an engaging means
30
on the other side of the boot
100
. When unfasten the buckle device, the user pulls the lever member
12
about the pin
120
and the strap head
10
will be also pivoted about the pin
111
so as to loosen the strap
11
. There is a potential risk that when the lever member
12
is unintentionally impacted, the strap
11
is loosened. In a hockey game, impact between players is so frequent that the lever members are likely lifted during playing the game. Although a locking means
121
is employed to secure the lever member
12
, the locking means
121
is located on a distal end of the lever member
12
so that it will be pushed unintentionally.
The present invention intends to provide a buckle device that has a protrusion extending from a bottom of the lever member and the base has a recess on a top thereof so that the protrusion can be securely engaged with the recess in the base to prevent from unexpectable lift.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a buckle device for skates and comprising a base having two lugs and a tubular member extending from a top of the base. The tubular member has a recess defined in a top of the tubular member. A lever member has two legs and the two legs are pivotally connected to the two lugs. A protrusion extends from a bottom of the lever member and is disengagably engaged with the recess in the tubular member. A strap head is pivotably connected between the two legs of the lever member and a toothed strap extends from the strap head and is disengagably connected to an engaging means.
The object of the present invention is to provide a buckle device that has a protrusion on the lever member and the protrusion is engaged with a recess in the to base so as to secure the lever member in position.
These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.
