ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a hat device. More particularly, the present invention relates to a hat device which has an extensible visor.
Referring to
FIG. 7
, a conventional hat device has a main body
30
, a fixed peak
31
disposed on a front portion of the main body
30
, and an extensible visor
40
engaged with the fixed peak
31
. An insertion block
41
is disposed on the extensible visor
40
. The insertion block
41
has two opposite lateral teeth
42
. A pair of L-shaped racks
32
are disposed on the fixed peak
31
. Each L-shaped rack
32
has a front block
34
and a plurality of serrations
33
. Each lateral teeth
42
engages with the respective serrations
33
. The extensible visor
40
can be extended. Each insertion block
41
moves along the respective serrations
33
of the L-shaped rack
32
. However, the frictional engagement between the serrations
33
and the lateral teeth
42
is very rigid without any elasticity so that it is very difficult to retract the extensible visor
40
or extend the extensible visor
40
while the user does not exert force along the direction of the L-shaped rack
32
. This structure is disclosed by U.S. Pat. No. 5,839,125.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a hat which has an extensible visor to be extended.
In accordance with a first preferred embodiment of the present invention, a hat device comprises a main body, a fixed peak disposed on a front portion of the main body, and an extensible visor engaging with the fixed peak. A blocking flange is disposed on an edge of the extensible visor. The extensible visor has two lateral elastic plates and two grooves. The fixed peak has a slot and a periphery flange. The extensible visor is inserted in the slot of the fixed peak.
In accordance with a second preferred embodiment of the present invention, a hat device comprises a main body, a fixed peak disposed on a front portion of the main body, and an extensible visor engaging with the fixed peak. A blocking flange is disposed on an edge of the extensible visor. The fixed peak has a slot, a periphery flange, and two rows of corrugated serrations. The extensible visor has two lateral elastic plates, two grooves, and two rows of lateral teeth engaging with the corrugated serrations. The extensible visor is inserted in the slot of the fixed peak. When the extensible visor is retracted to the utmost, the blocking flange of the extensible visor and the periphery flange of the fixed peak block each other.
