Abstract

PURPOSE:To securely prevent an air flow from leaking and prevent a sealing member from being delaminated, by a construction wherein a flange part making contact with the rear surface of a sealing member is provided on the outside of a slant press contact part. CONSTITUTION:With an operating body 22 turned from the front side, a shutter 18 is turned together with a shaft 17 through an interlocking rod 23 and an operating rod 24, whereby an air passage in a main body 11 of the ventilator is opened or closed. Where the shutter 18 is located at a fully opened position or a closed position, a positioning projected part 26 of a slit 25 is engaged with a stopper pin 27 to maintain the shutter 18 at the opened position or the closed position. Where the shutter 18 is located at the closed position, the slant press contact part 19 thereof makes contact with corner parts of the inner periphery of the sealing member 16, and the flange part 20 makes contact with the rear surface of the sealing member 16, whereby the air flow is cut off.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] Water (1) relates to a ventilator for use in an air vent of an automobile.

[Technical background of the invention and its problems]

Conventionally, a ventilator used in an air outlet of a car, etc., has a shutter 3 at the rear part of a ventilator main body 1 in the shape of a rectangular tube to rotate a shutter 3 at a lower part @2, as shown in FIGS. 4 to 6, for example. A sealing material 4, which is slightly larger than the shack 3, is glued to the upper, lower, inner and outer sides of the shutter 3, which is movable, and is larger than the shack 3. The shaft 2 of the shack 3 is connected via the link interlocking mechanism 6, and the shack 3 is rotated by rotating the operating body 50 times to open and close the ventilation passage of the ventilator body 10, as shown in FIGS. 5 and 6. I'm trying to keep up with it.

However, in such a device, a sealing material 4 that is slightly larger than the shack 3 is adhered to the shutter 3 to prevent air leakage, so that the sealing material 4 is applied to the ventilator body 1 each time the shutter 3 is opened or closed. It is easy for the sealing material 4 to rub against the other hand, causing it to peel off and generate abnormal noise.

(Objective of the Invention) The present invention is intended to solve the above-mentioned point 4, and aims to reliably prevent river leakage and prevent peeling of the sealing material. It is something.

(Summary of the Invention) The pendilator of the present invention has a shutter rotatably provided at the rear of the ventilator main body in the form of a ventilation cylinder, and a shutter is provided at the front of the ventilator main body [connected to the operating body]. In a pendilator in which the shutter is opened and closed by operating an operating body, a frame-shaped rib is provided in an inclined manner on the inner rear side of the ventilator body, a sealing material is adhered to the rear surface of this rib, and the above-mentioned An inclined pressure contact portion is formed on the outer periphery of the shutter to contact a corner portion of the inner periphery of the sealing material, and a flange portion that contacts the rear surface of the seal shrine is formed on the outside of the inclined pressure contact portion. It is characterized by this.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 3.

Reference numeral 11 designates a rectangular cylindrical vent rake main body, which has an air outlet 13 with a front grill 12 formed at its front end, and a nozzle mounting port 14 at its rear end. Further, a frame-shaped rib 15 is integrally provided along the inner circumferential side of the inner side of the nozzle mounting port 14 in an inclined shape with the upper part facing backward, and a corresponding frame-shaped rib 15 is provided on the rear surface of this rib 15. A sealing material 16 is adhered.

A shutter 18 is rotatably mounted on the lower shaft 11 inside the nozzle mounting port 14 of the bench rake main body 11. The shutter 18 has an inclined pressure contact portion 19 formed on its outer circumference that contacts a corner of the inner circumference of the sealing material 16, and a rear surface of the sealing material 16 on the outside of this inclined pressure contact portion 19. An abutting flange portion 20 is formed.

A substantially circular operating body 22 is rotatably provided on one side of the front part of the ventilator main body 11 with a support shaft 21, and one end of an interlocking rod 23 is rotatably connected to this operating body 22. One end of an operating rod 24 is rotatably connected to the other end of the rod 23, and the other end of the operating rod 24 is connected to the shaft 17 of the shutter 18.
is fixed to. Also, on the inside of the operating body 22.
A groove 25 is formed in the arc-shaped sleeve 1 around the two-part support shaft 21, and positioning protrusions 26 protrude from the slit 25 near both ends. A retaining pin 27 protruding from the side surface of the bench rake body 11 is inserted.

), and by rotating the control lever 22 from the front side, the shutter 18 is rotated to @17 through the interlocking rod 23 and the operating rod 24 (), as shown in FIGS. 2 and 3. As shown in the figure, the communication passage of the ventilator main body 11 is opened and closed. 1
At this time, when the shutter 18 is in the most open position and the closed position, the positioning protrusion 26 of the sleeve 1-25 engages with the 11th pin 27, and the shutter 18 is held in the open/closed position. .

When the shutter 18 is in the closed position, the contact pressure part 19 contacts the corner of the inner circumference of the sealing material 16, and the flange part 20 contacts the rear surface of the sealing material 16. close to each other and block ventilation.

[Efficacy of invention]

According to the present invention, when the IT ivy is in a closed base state,
At the same time that the inclined contact pressure part of the Shitotsuta comes into pressure contact with the corner of the inner circumference of the seal H adhered to the rear surface of the glue J in the Henbrake body, the flange part of the shutter comes into contact with the rear surface of the seal material.
It can reliably block ventilation and prevent air leaks.
It tends to be used repeatedly over a long period of time, and the temperature is the same as before.
There is no chance that the sealing material will rub or peel off.

[BRIEF DESCRIPTION OF THE DRAWINGS] Fig. 1 is a perspective view showing one embodiment of the penbrator of the present invention, Figs. FIG. 4 is a perspective view of a conventional hendilator, and FIG. 5 d5 and FIG. 6 are sectional views showing its open and closed states.
