Abstract

PURPOSE:To improve the air-stream cutting-off effect by fixing a cutting-off plate having an opening port equipped with a slidable member at the back of a louvre and interlockig the slidable member with the louvre, in a ventilator equipped with louvre for car. CONSTITUTION:When a louvre 6 is turned to the upper side of revolution stroke, a slidable member 29 is slided downward in a slide groove 26 by a connecting rod 27 and set to a storage position. Therefore, an opening port 25 is opened to permit communication through a ventilator duct, housing 5, opening port 25, louvre 6, and car interior. When the louvre 6 is turned downward, the slidable member 29 is slided upward to close the opening port 25, and inflow of air into the car interior is cut-off. Thus, the cutting-off effect can be improved by constituting the louvre and the cutting-off member in interlocked state.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilator shut mechanism, and more particularly to a ventilator shut mechanism having a simple structure and improved airflow blocking effect.

As shown in Figure 1, various vehicles including passenger cars are equipped with ventilators 2 at various locations on the vehicle body panels, such as the instrument panel 1, to blow air taken in from the air conditioner or the outside of the vehicle into the vehicle interior. Conventional examples of such a ventilator 2 include those shown in FIGS. 2 and 3, for example. This ventilator 2 has a box structure 1, forms an air passage 10, has a housing 5 whose front end opens toward the interior of the vehicle, and is rotatable near the front 4 opening in the housing 5. The installed looper 6 and the air 5L blocking member 8 rotatably provided in the air passage 10 behind the looper 6
It consists of The looper 6 is made up of various combinations of rectifying plates 6a and vane members 6b extending in the vertical and horizontal directions, and is rotatably supported on the gA wall of the swivel ring 5 by a support shaft 9 extending in the horizontal direction. A knob I is provided at the front end of the looper 6, so that the flow direction of the air flowing out from the grill opening into the single room can be changed by changing the looper 60. The air flow blocking member 8 is connected to the rotating shaft 1
It consists of a panel member which is rotatably installed on the side wall of the hatching 5 by means of a panel member 5 and has 16 feet of protective covers made of an elastic material attached to both ends. This air flow blocking member 8 includes: - an arm 11 fixed to one end of a rotating shaft 15 on the outside of the housing 5; The rotation operation is performed by an operating mechanism 20 consisting of a link 11 whose operation is ensured by a hole 19. A housing 12 is attached to the tip of the operating mechanism 20, while a slide groove 13 is formed on the front surface of the housing 5.
By moving the knob 12 up and down, the link l1fc
The air passage 10 is opened and closed by rotating the support shaft 14 and rotating the rotation shaft 15 and the air flow blocking member 8 in the direction of arrow S in FIG. 3 via the arm 17tl. In FIG. 1, reference numeral 3 indicates instruments, and reference numeral 4 indicates an operating section of the air conditioner.

However, in such a conventional ventilator 2, the air blowing louver 6 and the air blocking member 8 of the ventilator 2 are configured independently from each other, and the operation for activating each is required. Since the mechanism also has a separate structure, there are problems in that the number of parts increases and the manufacturing cost is high. Furthermore, since the structure is a 4i iron, there is a risk that assembly workability will be poor. Furthermore, since a slide groove 13 is provided on the front surface of the housing 5 of the ventilator 2 in order to attach the operating mechanism 2o of the air flow blocking member 8, all ventilators 2 using this type of housing 5 are equipped with an air flow interrupter. There was some inconvenience in having to install a 4S.

In another type of ventilator, the rectifier plates 6a or 6b' attached to the louver 6 are made rotatable and connected to each other by connecting rods, and by operating the knob 1, the rectifier plates are closed all at once, allowing the air to flow. There is a type of ventilator that uses a R-cut (so-called looper shut method), but this type of ventilator has a problem in that the air flow leaks through the rectifying plate and the rectifying plate.

The present invention was made by focusing on the above-mentioned problems of conventional plums.The purpose of the present invention is to create a new type that has a relatively simple structure and can effectively block air flow. It is an object of the present invention to solve the above-mentioned problems of the prior art by providing a shaft mechanism or airflow blocking mechanism for a ventilator.

In the present invention, an air flow blocking mechanism is provided in the housing circle of the ventilator and behind the wind direction adjustment looper, the louver is operatively connected to the air flow blocking mechanism, and the air flow is blocked by rotating the louver. The main point is that the mechanism is operated to open and close. The air flow blocking mechanism includes a shielding plate having an opening and installed across an air passage formed in the housing, and a sliding member slidably attached to the shielding plate. It is connected to a louver. Therefore, when the louver is rotated up and down or left and right, the slide member slides along the shielding plate in response to the movement of the louver, opening and closing the opening and blocking the flow of air through the ventilator. , I'm going to release it. Therefore, the air blocking mechanism has advantages such as a simpler structure and more efficient power transmission for operating the air blocking mechanism.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 4 to FIG. 6 are diagrams showing one embodiment of the present invention.

The air blocking mechanism 21 according to this implementation row includes a ventilator 2
a shielding plate 24 attached to the rear position of the louver 6 in the air passage 10V:J formed in the housing 5;
It consists of a slide member 29 disposed within this shielding plate 24. The shielding plate 24 is made of a material that is relatively easy to mold, such as sweet acid resin, and has an overall curved cross-sectional structure, with a gate 25 formed at one end and a portion Q on the other side.
This forms a storage section 31, and both mlc of the opening 25 have slide grooves 26 made of cedar that extend up to the storage section 31. This shielding plate 24 is mounted and fixed by mounting members 30 provided correspondingly to the upper and lower lids of the housing 5 so that the opening 25 faces toward the air passage 10. This mounting member 3
0 is provided with a claw 3z or a bottle that protrudes outward, and the shielding plate 24 is attached by one-touch engagement of the claw 32 into a locking hole 33 provided in the housing 5. Although it is designed to come with a fixed bath, you can also attach and fix it using the method of boiling bath Mata a bath No. N.

The slide member 29 is molded with the shielding plate 24 and materials such as Kaisei Kimono Co., Ltd., all of the above-mentioned shielding plate 240 bay L shape Vc,
It engages with a slide 426 provided on the shielding plate 24 and loads the sliding layer from the opening 25 to the storage section 31. A connecting member 42γ having a joint member 28 at its tip is protruded from the edge portion of the slide member 29.

- 10,000, the looper 6 is a looper box 35 formed by molding a single piece of fluorescent plate 6a that opens in the front and back direction and extends laterally in the middle part, and is also installed at a predetermined interval in this looper box 35 yen. It consists of a plurality of vane members 6b. The vane member 6b has a support @37t- at each upper and lower end.
The support shaft 31 is rotatably mounted by inserting it into a mounting hole 36 provided in the upper and lower walls of the louver box 35. In addition, a knob 7 protruding forward is attached to one of the vane members 6b, while each vane member 6
b is integrally connected by the operating rod 23 connected via a thin resin hinge 38 at the rear edge. Therefore, by moving the knob 1 up and down, the looper 6 can
The entire looper box 35 can be rotated vertically around the support 9, and the knob? e By moving it left and right, the entire vane member 6i) can be rotated in the left and right direction.

The looper 6 and the slide member 29 of the upper air #r and release ffr mechanism 21 are operated by fitting a joint member 28 provided at the tip of the joint member 21 into the operating rod 23. has been successful. As shown in FIGS. 4 to 6, for example, the joint member 28 is composed of a gripping and connecting type joint member, and is integrally fixed with the operating rod 23 against vertical movement. For the same movement in the left and right directions, the joint member 28 engages movably along the operating rod 23 so as to absorb the angular displacement between the operating rod 23 and the connecting rod 27 in the left and right direction. It's happening. Therefore, the slide member 29ri, the looper 6
The opening 25 of the shielding plate 24 can be opened and closed by sliding along the slide groove 26 in conjunction with the vertical rotational movement of the shielding plate 24 . Further, when the vane member 6b is rotated, the slide section 29 does not operate at all and remains in a stopped state.

Because of this configuration, the air flow blocking mechanism 21 according to the present embodiment slides in conjunction with this rotational movement when the loop/<-6 is rotated to a position near the upper side of its rotational stroke. The member 29 is slid downwardly into the retracted position shown in FIG. Therefore, the opening 25 is in an open state, and the air flowing through the ventilator duct 9 and into the housing 5 passes through the opening 25t, and after being rectified by the looper 6, exits from the outlet opening of the ventilator 2. I send it to the inside of the car. In order to change the muddy direction of the blowing air, when the knob T is rotated in the vertical direction by -/<-6k, the slide member 29 slides in conjunction with this, so the opening 25
Although the opening degree of the looper 6 changes, the rotational position of the looper 6 and the corresponding sliding position of the slide member 29 are set so that a sufficient amount of air can be blown out under normal usage conditions. Furthermore, as shown in FIG. 5, the bottom part 24a of the shielding plate 24 has a linear structure that smoothly continues to the curved part provided with the opening 25 in order to contact the bottom surface of the housing 5. Since the shielding plate 24 and the slide member 29 are made of a somewhat elastic material such as sweet acid resin, the slide member 29 warps to the extent that it does not fit in the housing portion 31F3.
It can be stored without any resistance.

Next, when the louver 6 is rotated to the lower position in order to cut off the air from the ventilator 2, the slide member 29 moves upward in the figure along the guide groove 26. 6, and closes the opening 25, blocking air flow i10, as shown in FIG. Therefore, the wind from the ventilator duct is blocked by the airflow blocking mechanism 21 and does not flow to the outlet opening of the ventilator 2.

By rotating the looper 6 in this way, it is possible to block the next flow of air from the ventilator 2, so depending on the type of car or the preference of the user! If the airflow blocking mechanism is no longer needed, the operating rod 23 and connecting rod 2
By removing the tie between 7 and 1, or by not installing the air flow blocking mechanism 21 at all during the manufacturing stage,
It is interesting to look at the ventilator 2 of the air/mud blocking type or the non-blocking type without changing its appearance at all.

As explained above, according to the present invention, the ventilator housing includes a shielding plate and a slide member which is slidably disposed on the instep of the shielding plate and is operatively connected to the looper. Since the ventilator is equipped with a shutoff mechanism, the ventilator has fewer components and is easier to manufacture than a ventilator, which helps reduce manufacturing costs.

Furthermore, since the air blocking mechanism can be operated by being operatively connected to the looper within the housing of the ventilator, the exterior structure of the ventilator should be exactly the same whether or not the air blocking mechanism is installed. I can do it.

Therefore, one type of ventilator curing can be used to configure ventilators with and without an air flow blocking mechanism, improving the versatility of parts and helping to reduce parts costs. Various effects can be obtained, such as being able to
