BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an outlet vent controller of air conditioner, and more particularly to an outlet vent controller that can adjust rate of discharge.
2. Description of Prior Art
So far, in the home or the office, the uniform chill or heat system is employed cooperating to each outlet vent located on every room, therein a grid window used for controlling the rate of discharge is built upon the outlet vent, as shown in FIG. 1, located on the wall, which is consisted of a panel 1, a set of swing blades 2 and an actuating device 3′, wherein said panel 1 has vertical or horizontal grid 11 arranged in, and a set of shoe plates 12 built upon the back side holding all the swing blades 2 with both ends of one side in pivot connection, and a set of pitman arms 4 set upon the both sides of the swing blade 2 linking the set of swing blades 2 into together in pivot connection; said actuating device 3′ is a dolly bar 31′ passing through a through-slot 13 built upon one side of the grid 11 on the panel 1 links with said pitman arm 4, and approaching middle position of it is pivoted on the shoe plate 12 working as a lever for adjusting the open angle of the swing blades 2 as an actuating device 3′.
With reference to FIG. 1 and FIG. 2, when the grid 11 is in close state, the swing blades 2 is set into covering the back of the panel so that the all grid 11 is shaded completely to carry out closing outlet function, in this case, said dolly bar 31′ of the actuating device 3′ is shifted on the top end of the through-slot 13, and as tenting to adjust the rate of discharge, as shown in FIG. 3, by shifting the dolly bar 31′ of the actuating device 3′ downward in front of the panel 1, under the action of leverage, the pitman arm 4 located on the another end of the actuating device 3′ is left up to bring all the blades 2 in the set to raising one side up synchronously so as to open the outlet, along with the dolly bar 31′ moving down, the open angle of every blades 2 is changed to determine the rate of discharge.
But after studying the detail of the above-mentioned grid controller, there are following shortcomings existed:
- 1. because said actuating device is a dolly bar, as shifting it, the contacting area with the fingers is so small that bigger pressure exerts on the tips of fingers to make hand uncomfortable;
- 2. because the dolly arm is pivoted on the shoe plate, as shifting it downward or upward around the pivot point in the middle range, the outer tip end of the dolly bar will stretch out from the panel reaching longest, not only so as to affect exterior, but also easily to scratch human's body or face especially to children, because the panel is usually located on the wall about one meter above the ground.
OBJECTS AND SUMMARY OF THE INVENTION
It is therefore a main object of the present invention to provide an outlet vent controller operated easily without any danger of scratching occurred by the dolly bar.
For achieving the object, the present invention provides technique project is to set a grid controller on the through-slot at one side of the grid window on the panel, therein said grid controller includes a sliding button and a shifting lever gearing together replace of the conventional dolly bar, said sliding button is set upon the through-slot, and said shifting lever is pivoted on the shoe plate, one end of the shifting lever is in a gear section for gearing with the inner rack bar end of the sliding button, the another end is pivoted to the pitman arm linking with the blades.
Said sliding button has a pushing portion formed on the top end with a concave for facilitating to finger contacting.
Said concave of the sliding button is checked crossly into rose work for antiskid.
The back side of the sliding button is built upon with one or more meshing gears to from a rack bar.
Said sliding button has a couple of barbed catching dogs built upon the one side of the back side, thereby crossing the side of the through-slot for locating.
Said panel, coordinating to the barbed catching dogs, has a groove built upon the back side of the through-slot.
Said barbed catching dog has a step built upon the tip end for launching into the through-slot.
Said shifting lever has a circular head in one end for matching to the sliding button, on which meshing gear section is built on.
Said shifting lever has a pivoting slot built upon for pivoting to the shoe plate.
By means of the above-mentioned technique project, the gearing meshing structure of the sliding button and the shifting lever, the contacting area of the finger and the sliding button is increased, additionally cooperating to the checkered concave surface to make the finger feel more comfortable as operating on the sliding button; as sliding the sliding button in see-saw motion for adjusting the open angle of the blades, the sliding button will not stretch out from the through-slot any more, so as to overcome the shortcomings of the conventional products, meanwhile improve the effect of outward appearance and safety.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to FIG. 4 and FIG. 5, the present invention provides an outlet vent controller, which is comprised of a panel 1, a set of swing blades 2 and a grid controller 3.
Said panel 1 has a vertical or horizontal grid 11 arranged and a through-slot 13 built upon beside the parallel side of the grid 11, and four shoe plates 12 built on the back side surrounding said grid 11, and a proper number of swing blades 2 pivoted on a pair of opposite shoe plates 12 with both ends of one side respectively, and a couple of pitman arms 4 separately linking the both ends of another side of every swing blade 2 to form a set;
The feather of the present invention is that the grid controller 3 is constituted of a sliding button 31 and a shifting lever 32;
Said sliding button 31, as shown in FIG. 5 and FIG. 7, has a concave 311 built on the top side cooperating to the tip end of finger, for antiskid the concave 311 is checkered crossly into rose work 312; and it also has a block extended out on the back side with one or more meshing gears to form a rack bar 313 built upon the back surface; and said sliding button 31 also has a pair of barbed catching dogs 314 built on the one side of the block at the back side, meanwhile the barbed catching dog 314 has a step 315 extended out on the tip end;
Said shifting lever 32 has both circular heads, in which one matching to the rack bar 313 of said sliding button 31 is cut into meshing gear section 321 such as a gear; the another end is pivoted on the pitman arm 4 with a rivet 5 fitting into a pivot slot 322, meanwhile the shifting lever 32 is pivoted on the shoe plate 12.
In combination, as shown in FIG. 5, the sliding button 31 is stretched through the through-slot 13 of the panel 1 with the back block, and located on the slot 13 by the couple of barbed catching dogs 314 catching on the back side, as shown in FIG. 6, so that the catching dogs 314 catch into the groove 131 on the back side of the through-slot 13 for preventing the barbed catching dogs 314 from loosing off occurred by long term fatigue, meanwhile the top side contacting concave 311 of the sliding button 31 is located on the front side of the panel 1; said shifting lever 32 meshes to the rack bar 313 of the sliding button 31 with the meshing gear section end 321, when the swing blades 2 are in close state, the sliding button 31 is just shifted on the top end of the through-slot 13.
When tenting to open the grid, as shown in FIG. 7, the finger presses and pushes the contacting concave 311 the sliding button 31 downward along the through-slot 13, due to the increased contacting area, the hand will feel more comfortable, meanwhile the rack bar 313 on the back side drives the meshed gear section end 321 of the shifting lever 32 to turn around the pivot point set on the shoe plate 12, synchronously the another end of the shifting lever 32 lefts the pitman arm 4 to raise all the swing blades in the set to open the outlet vent; as turning the shifting lever 32, the pivoting rivet 5 can slide in the through-slot 13 so that the sliding button 31 may be not pushed out from the front side of the through-slot 13, therefore overcoming the shortcomings of the prior art, meanwhile improve the effect of outward appearance and safety.
Conversely, pushing the sliding button upward along the through-slot 13, the swing blades 2 will be closed, so the outlet vent is shut down too.
