Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a register that covers the indoor end of a ventilation hole penetrating a wall surface or the like so as to be openable and closable.

(Prior Art) As a conventional register, for example, there is one described in "Kansai Branch Type Detail Sheet Collection e-206-3-1" published by the Kansai Branch of Housing and Urban Development Corporation. FIG. 6 is a sectional view showing the above-mentioned conventional example, in which a flange 3 is provided at the indoor opening end of the ventilation hole 2 penetrating the wall surface 1 of the building, and a plurality of rings are concentrically arranged inside the flange 3. The arranged covers 4 are screwed on to cover the opening ends of the ventilation holes 2 on the indoor side. Further, a shutter 5 is provided with a plurality of diagonal rings whose inner circumferential ends are in sliding contact with the inner rings and whose outer circumferential ends are in contact with the outer rings from the indoor side, and is movable in the axial direction toward the cover 4. It is inserted into. A handle 6 protruding from the center of the indoor side of the shutter 5 is used to move the shutter 5 in and out to open and close the gap formed between the rings of the cover 4, thereby opening and closing the ventilation hole 2.

8 is a sleeve inserted into the wall surface 1 to form the ventilation hole 2, and 9 is a louver attached to the open end of the ventilation hole 2 on the outdoor side.By providing this louver 9, rainwater etc. can be prevented from entering the ventilation hole 2. We are trying to prevent it from entering.

Usually, the above-mentioned ventilation holes are provided at a high position, such as near the ceiling surface, so there is a problem in that operability is poor if the handle located on the front of the cover is directly operated.

(Problem to be solved by the invention) The present invention was made to solve the problems of the conventional technology, and even if the ventilation hole is located at a high position, it can be opened and closed very easily. Our objective is to provide a register for ventilation holes that allows for ventilation.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a cylindrical body to be attached to a ventilation hole penetrating a wall surface, a cover coupled to an open end of the cylindrical body, and a central part of the back surface of the cover. a protruding hollow shaft; a disk rotatably and slidably mounted outside the hollow shaft on the back surface of the cover; a plurality of slits formed radially in the cover and the disk; A first operation string hangs down from the front of the cover through the inside of the shaft, and a second operation string hangs down from the front of the cover after passing through the inside of the hollow shaft after being tied to the disk and bypassing the rear end opening of the hollow shaft. An operation string, a protrusion provided on the inside of the cylindrical portion formed on the cover at an angle with respect to the axis, and a notch provided on the periphery of the disk for engagement with the protrusion. It is said that

(Function) When the first operation string is pulled and the disk is joined to the back of the cover, the slit in the cover and the slit in the disk are in opposite phases, so the slit in the cover is closed. Ventilation holes are closed. Furthermore, when the second operating string is pulled to separate the disk from the cover, the disk rotates due to the guiding action of the notch in the disk and the protrusion on the cylindrical part of the cover, thereby aligning the slit in the disk with the slit in the cover. The phases match and the ventilation holes are opened.

Therefore, the ventilation hole can be opened and closed simply by pulling the operating string hanging down from the front of the cover and moving the disk.

(Example) Examples are described in FIGS. 1 to 5,
Fig. 1 is an exploded perspective view of the main parts of the ventilation hole register according to the present invention, Fig. 2 is a front view of the same assembled state, Fig. 3 is a cross-sectional view taken from Fig. 2, and Fig. 4 is a guide means. FIG. 5 is a front view of a certain protrusion, and FIG. 5 is an exploded perspective view of the supporting portion of the disk.

In these figures, a flange 11 is provided on a cylindrical body 10 that is attached to a ventilation hole penetrating a wall surface,
A cover 12 is screwed to the inside of this cylindrical body 10. The cover 12 has eight slits 1.
3 and 13 are formed radially with equally spaced pitches, and the inside of the ventilation hole is communicated with the room through these slits 13 and 13.

A hollow shaft 1 is provided at the center of the back of the cover 12.
A disk 15 is inserted into the shaft 14 so as to be rotatable and slidable in the axial direction. The disk 15 has eight slits 16, 1 at the same intervals as the slits 13 of the cover 12.
6 is formed radially, and by rotating this disk 15 on the back side of the cover 12,
Slits 13, 13 formed in the cover 12
In other words, the ventilation holes can be opened and closed.

Further, as shown in FIG. 5, the hollow shaft 14
A slot 17 is provided along the axial direction. Further, a guide rod 19 is provided on the boss portion 18 of the disk 15 along the diameter direction, and the width of this guide rod 19 is made smaller than the interval between the slots 17. The disk 15 is inserted into the outer surface of the hollow shaft 14 by inserting the guide rod 19 of the boss portion 18 into the slot 17. The guide rod 19 inserted into the slot 17 is formed to have a width that allows the disk 15 to rotate within a predetermined range.
The disk 15 (boss portion 18) is allowed to rotate relative to the cover 12 (hollow shaft 14) by the angle at which the disk 9 rotates.

A first operating string 20 is tied to the guide rod 19, and is suspended from the center of the front surface of the cover 12 through the inside of the hollow shaft 14, and is attached to the boss portion 18. In the case of the first operation string 20, the fixed second string 21 is introduced inside the hollow shaft 14 after bypassing the groove 22 provided at the rear end opening of the hollow shaft 14. Similarly, it hangs down from the center of the front of the cover 12. In addition, 23, 24
is a handle provided at the tip of the operating strings 20, 21.

On the other hand, protrusions 26, 26 are provided on the inside of the cylindrical portion 25 formed on the back surface of the cover 12, and these protrusions 26, 26 and notches 27, 27 provided on the outer peripheral edge of the disk 15 are slidable. It can be freely engaged. Here, as shown in FIG. 4, the protrusions 26, 26 are inclined with respect to the axis of the cylindrical portion 25, and their starting and terminal ends are respectively formed parallel to the axial direction. There is. Therefore, disk 1
When the disk 15 is moved along the hollow shaft 14, the disk 15 initially moves without rotating.
When it reaches the sloped portion, it rotates as the protrusion 26 slopes, and when it reaches the end of the sloped portion, it moves without rotating again.

The maximum rotation angle of the disk 15 is determined by the slit 1.
When the disc 15 collides with the stopper 28 fixed to the rear end of the hollow shaft 14, the slit 1 of the disc 15
The phases of 6 and 16 correspond to the slit 1 of the cover 12.
The phase is made to match the phase of 3 and 13.

In the register configured as described above, by pulling the first operation string 20, the disk 15
is attached to the back surface of the cover 12, the phase of the slits 16, 16 of the disk 15 is the same as that of the cover 12.
Since the phase of the slits 13, 13 is opposite to that of the slits 13, 13 of the cover 12, the slits 13, 13 of the cover 12 are closed, thereby cutting off communication between the room and the ventilation hole.

On the other hand, when the second operating string 21 is pulled, the guide rod 19 connected to the second operating string 21 is pulled to the right in the figure, and the disk 15 is separated from the cover 12. A notch 27 provided on the outer periphery of the disk 15,
27 is a protrusion 2 provided on the cylindrical portion 25 of the cover 12
6 and 26, the disk 15 rotates as it moves away from the cover 12, and finally the slits 16 and 16 of the disk 15 rotate.
The phase of the cover 12 is made to match the slits 13, 13 of the cover 12, so that the interior of the room and the ventilation hole are communicated with each other.

In this way, when the second operating string 21 is pulled, the slits 13, 13 of the cover 12 are opened, and the ventilation hole and the room are communicated through the slits 13, 13, so that the desired ventilation effect is performed. . When the ventilation function is to be stopped, the first operation string 20 is pulled and the disk 15 is slid to the left in the figure via the guide rod 19 and the boss portion 18 and joined to the back surface of the cover 12. For example, the first and second operation strings 20 and 21 are closed so that the slits 13 and 13 of the cover 12 are closed by the disk 15.
By selectively operating the ventilation holes, the ventilation holes can be opened and closed.

In the embodiment, portions parallel to the axial direction of the shaft 14 are provided at the ends of the protrusions 26, 26, respectively, and these function as stoppers to prevent deterioration of operability due to the disk 15 being caught or the like. However, the specific configuration of the rotation guide means for the disk 15 is not limited to the embodiment.

In addition, in the embodiment, two independent operation strings 20, 2
1 is provided for selection operation, but the tips (hanging ends) of these operation strings may be connected in a loop shape.

(Effect of the invention) As explained above, according to the invention, the slit forming the cover can be opened and closed by pulling the operating string hanging down from the front of the cover that covers the opening of the ventilation hole. Since the ventilation hole can be opened and closed, the ventilation hole can be opened and closed very easily no matter where the ventilation hole is provided.
