ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a transfer register that is located in an instrument panel of a vehicle such as an automobile, a vessel or an airplane and is connected to an air conditioner the vehicle.
Japanese Unexamined Utility Model Publication No. 3-87155 discloses a transfer register
100
, which is illustrated in FIG.
10
. The transfer register
100
includes a duct
101
. Horizontal front deflector plates
102
are pivotally supported in the duct
101
. The front deflector plates
102
are connected by a front connector rod
103
, which is located at a side of the front deflector plates
102
. The front connector rod
103
permits the front deflector plates
102
to pivot vertically in a synchronized manner.
Vertical rear deflector plates
104
are pivotally supported in the duct
101
. The rear deflector plates
104
are connected by a rear connector rod
105
. The rear connector rod
105
permits the rear deflector plates
104
to pivot horizontally in a synchronized manner.
A knob
106
is located on the center one of the front deflector plates
102
. The knob
106
slides horizontally on the associated front deflector plate
102
. One end of the knob
106
is coupled to the center one of the rear deflector plates
104
. The one end moves along the associated plate
104
. When the knob
106
is pivoted vertically, the front deflector plates
102
are synchronously pivoted by the front connector rod
103
, which vertically changes the direction of air exiting the opening
101
a
of the duct. When the knob
106
is slid horizontally, the rear deflector plates
104
are synchronously pivoted by the rear connector rod
105
, which horizontally changes the direction of the air exiting the opening
101
a.
The duct
101
, the front and rear deflector plates
102
,
104
, the front and rear connector rods
103
,
105
and the knob
106
are separately formed with resin. When assembling the transfer register
100
, the front deflector plates
102
are pivotally installed in the duct
101
. Then, the front connector rod
103
is attached to the front deflector plates
102
. Thereafter, the rear deflector plates
104
are installed in the duct
101
, and the rear connector rod
105
is attached to the rear deflector plates
104
. Subsequently, the knob
106
is attached to the center one of the front deflector plates
103
. One end of the knob
106
is engaged with the center one of the rear deflector plates
104
. The transfer register
100
has a relatively large number of parts and the assembly is complicated. Accordingly, the cost is relatively high and the manufacture is troublesome.
SUMMARY OF THE INVENTION
Accordingly, it is an objective of the present invention to provide a transfer register that reduces the number of parts and is easy to assemble.
To attain the above-mentioned object, the present invention provides a method including molding a set of deflector plates in a first mold with a first material, removing the deflector plates from the mold, placing the deflector plates in a second mold, molding a duct to the deflector plates in the second mold using a second material. The first material does not adhere to the second material. The molding includes forming an engaging rim in the duct for connecting the duct to another duct, and removing the deflector plates and the duct from the second mold. The deflector plates pivot with respect to the duct when the molding of the duct is finished.
The present invention also provides a register. The register has a first deflector plate and a second deflector plate. A first duct supports the first deflector plate such that the first deflector plate pivots with respect to the first duct about an axis. A second duct, which is separate from the first duct, supports the second deflector plate such that the second deflector plate pivots with respect to the second duct about an axis. The axis about which the first deflector plate pivots is perpendicular to the axis about which the second deflector plate pivots. The first duct is connected to the second duct such that the register is unitary.
Other aspects and advantages of the invention will become apparent from the following description, taken in conjunction with the accompanying drawings, illustrating by way of example the principles of the invention.
