ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a base assembly for a windshield sunshade of an automobile, particularly having a sunshade holder being manually pulled outwardly from a coupling rod of a pivot coupler, by which an insertion block of sunshade holder can compress a spring so that the sunshade holder can be separated from engagement recesses of a base unit and is adapted to be adjusted with various angles under the rotation of the pivot coupler, which the base assembly in the present invention is assembled easily and quickly and is more convenient for a user to operate in practical use.
2. Description of the Prior Art
A known conventional windshield sunshade of an automobile as shown in
FIGS. 1 and 2
includes a support base
10
, a shade curtain
11
, a circular rod
12
, an upper position block
13
, and a support rod
14
combined together.
The support base
10
has a plurality of threaded holes
100
in a bottom plate for screws
101
to fix the support base
10
on a flat surface
15
in front of a rear windshield sunshade of an automobile, a lengthwise curved-up portion
102
at a rear end for receiving the sunshade curtain
11
and the circular rod
12
therein, and an insertion recess
103
in a center of the top surface.
The shade curtain
11
has a pull grip
110
on an upper center end, which can be hung on a hook
130
of the position block
13
. The position block
13
also has a hole base
131
formed in a lower portion, and a curved-down portion
132
in a top to be fitted firmly with a lateral strip at a roof connect line
16
between a rear windshield and the roof of an automobile. Then the support rod
14
has an upper end inserted in the an insertion recess
103
of the support base
10
and a lower end inserted in the hole base
131
of the position block
13
. In case of need, the shade curtain
11
is pulled outwardly from the lengthwise curved-up portion
102
with the pull grip
110
being manually moved up to hang on the hook
130
of the position block
13
for shading the rear windshield.
However, the support base
10
of the known conventional windshield sunshade of an automobile is fixed in a definite preset direction, unable to adapt to various angles of different rear windshields of many styles of automobiles, which becomes a limit and disadvantage in practical use.
SUMMARY OF THE INVENTION
The main purpose of the invention is to offer a base assembly for a windshield sunshade of an automobile with a sunshade holder adapted to be adjusted with various angles, which can be assembled easily and quickly and is more convenient for a user to operate in practical use.
The main feature of the invention is to have a base unit with a plurality of engagement recesses each two respectively disposed in two opposite sidewalls of an engagement portion therein; a pivot coupler including a pivot base with a coupling rod disposed at one sidewall, a cavity located in an interior of the pivot base and passing through a central through hole of the pivot base and extending to a middle portion of the coupling rod, two opposite grooves respectively disposed in two opposite sidewalls of the coupling rod, and a spring placed in the cavity; a sunshade holder including a curved-up plate with a coupling housing disposed at one sidewall, a chamber located in an interior of the coupling housing for housing the coupling rod, two projecting ridges respectively positioned at two opposite sidewalls of the coupling housing and extending to the curved-up plate and engaged with the engagement recesses of the base, two insertion holes respectively disposed at the two opposite sidewalls of the coupling housing and communicating with the chamber, and an insertion block adapted to be inserted through the two insertion holes of the coupling housing and the two opposite grooves of the coupling rod so as to limit against the spring within said cavity of the coupling rod of said pivot coupler.
