DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation register provided as a ventilation port or an air supply port, which is manually opened and closed.

[0002]

2. Description of the Related Art A manual ventilation register provided as a ventilation port or an air supply port is used for controlling room temperature, taking in air, and the like, and various types of ventilation registers have been conventionally provided. For example, as shown in FIG. 6, a butterfly type ventilation register that opens and closes a wing body by providing a gear at the center of a cylindrical body, or a screw (screw) rotated by turning a knob at the center of the cylindrical body to form a circular Is a ventilation register that opens and closes and moves forward and backward, and a sliding ventilation register that closes an opening by turning a knob to slide a blade plate.

[0003] However, the ventilation register provided with the rotating mechanism of the gear and the screw has a structure in which the rotating force generated by the rotating mechanism is directly transmitted to the wing body and the circular gallery, so that the cover is provided on the rotating mechanism. Cannot be provided.

When used for many years without a cover, dust and sand, etc., accumulate in the rotating mechanism, and in addition to humidity due to temperature changes inside and outside the room, they may be solidified or clogged. There is a problem that the rotation mechanism cannot be opened and closed.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems, and an object of the present invention is to provide a ventilation register which can smoothly open and close a wing body even when used for many years. I do.

[0006]

In order to achieve the above object, a ventilation register according to the present invention comprises a pair of wings closing a ventilation opening, each of which is rotatably supported in the ventilation opening.
One end of the first connecting arm is locked closer to the center of the ventilation port than the rotation axis of one of the pair of wings, and the other end of the first connection arm is closer to the periphery of the ventilation port than the rotation axis of the other of the pair of wings. And one end of each of the two connecting arms is locked, and the other end of each of the connecting arms is locked to one operating arm, and the pair of wing bodies are moved through the connecting arms by sliding operation of the operating arm. Is rotated to open and close the ventilation port.

In this ventilation register, a hinge axis is provided in the middle of the wing body, and has a two-axis structure in which a pair of wing bodies are independently supported. In this way, by making the pair of wing bodies independent of each other, it is possible to prevent the opening and closing mechanisms from being densely arranged near the center of the ventilation register, and to make it difficult to obstruct the flow of ventilation. That is, most of the conventional ventilation registers have a uniaxial structure such as a hinge in which the rotating mechanism is provided along the diameter of the cylindrical body. What was hindered is solved by the present invention. In addition, since the opening and closing operation of the wing is performed by the operating arm and the connecting arm, there is no gear or screw in which fine particles such as dust and sand are accumulated, and the opening and closing operation can be performed smoothly even after long-term use. The sliding operation of the operating arm may be such that the operating arm slides right and left or a fulcrum may be provided to rotate in accordance with the installation place and the use condition.

In such a ventilation register, a rotatable lever protruding out of the ventilation port is provided, and one end of an operating arm is connected to a rotating shaft of the lever, and each connecting arm is connected to the other end of the operating arm. It is preferable that the other end of the operating lever is slid by rotating the operating arm in accordance with the rotation of the lever. In this way, the lever can be easily opened and closed simply by rotating (pinching and twisting) the lever.

An operating arm is disposed outside the wing by means of an operating arm recess formed on the outer periphery of the ventilation port, and one end and the other end of the operating arm are located on opposite sides of the wing. It is good to do so. By doing so, the operating force can be secured by using the operating arm length in a narrow range, the mechanism can be made compact, and the ventilation register itself can be made compact.

[0010] Furthermore, a fixing projection is provided on the outer peripheral side of the ventilation port of the operating arm, and a locking step for locking the fixing projection at the open position and the closed position of the wing body is provided on the outer peripheral surface of the ventilation port. Good to do. By doing so, the wing body is reliably fixed in the open state or the closed state, and the wing body does not open and close without permission due to the ventilation volume of the ventilation opening. Also,
Since a reliable response, such as a click feeling, can be obtained, the open / closed state can be checked only by the response.

[0011] With respect to the wing body of the ventilation register as described above, it is preferable that an overlapped portion is formed on the contact side of the wing body that contacts each other in the closed state. This is because the sealing portion in the wing body closed state is further improved by the overlapping portion.

It is preferable that a wing, an operating arm, and a connecting arm are incorporated in the cylinder, and the cylinder is attached to a wall as a ventilation port. By doing so, even if the ventilation register is broken, the ventilation register can be replaced for each unit.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the ventilation register according to the present invention will be described below with reference to the accompanying drawings. The ventilation register according to one embodiment of the present invention has various cylindrical shapes as shown in FIG.
Is formed as a general cylindrical body 5 and is inserted and mounted in a through hole formed in a wall surface. Actually, the cover is attached to the through hole to which the ventilation register is attached, and only the lever 1 that opens and closes the wings 4L and 4R is used in a state where it comes out of the cover.

As shown in FIG. 1, when the lever 1 is moved in the direction of the arrow, the wings 4L and 4R open and close. The lever 1 is connected to the operation arm 2, and the operation arm 2 is turned right and left in conjunction with the movement of the lever 1 with the connection 2a as a fulcrum (FIGS. 2 and 3). One end of the connecting arm 3L is locked to the wing body 4L, and one end of the connecting arm 3R is locked to the wing body 4R, and the connecting arm locking portion 2b of the operating arm 2 is connected to the connecting arm 3L, The other ends of the 3Rs are respectively locked.

As shown in FIG. 1, the operating arm 2 has a connecting portion 2a and a connecting arm locking portion 2b, and a fixed convex portion 2c for fixing the open or closed state of the wing body. The arm portion from the connecting portion 2a to the fixed convex portion 2c extends along the concave portion 5a for the operating arm of the cylindrical body 5 (FIG. 4).
In the closed state of the wing, the connecting arms 3L and 3R are locked at the rear surface of the wing through the outside of the wings 4L and 4R.
As shown in FIG. 4, a locking step 5b is provided in the concave portion 5a of the cylindrical body 5 to lock the fixed convex portion 2c, and the fixed convex portion 2c is opened by moving the lever 1 in the left and right directions of the arrow. The locking step 5b in the state or the locking step 5b in the closed state is locked.

When the operating arm 2 is rotated from the open state to the closed state or from the closed state to the open state, the fixed convex portion 2c slides on the concave portion 5a after releasing the locking step 5b. Also,
When the fixed convex portion 2c slides on the concave portion 5a, the operating arm 2 itself is pressed upward.
L and 4R can be fixed. The wing 4
The ventilation volume can be easily adjusted by finely adjusting the open / closed state of the L and 4R.

The connecting arms 3L and 3R shift from the closed state in FIG. 2 to the open state in FIG. 3 while maintaining the positional relationship as if the left and right arms were extended horizontally. As shown in FIG. 2, the connecting arm 3L has a curved shape so that the connecting arm 3L does not hit the wings 4L and 4R when the ventilation register is closed.
As shown in FIG. 3, a concave portion 6L is provided in accordance with the curved shape so that the connecting arm 3L does not hit the wing body 4L when the ventilation register is open. A locking hole 6a for locking the other end of the connecting arm 3L is provided in the recess 6L.

On the other hand, since the other end of the connecting arm 3R is locked by the locking portion 6b projecting from the wing 4R, it does not interfere with the wing 4R. The wing body 4R has a locking portion 6b.
In addition, in the closed state of the wing body shown in FIG.
The recess 6R is provided so as not to hit.

As shown in FIG. 5, the wings 4L and 4R are formed in a pair of squirrels, and have upper and lower horizontal upper portions 4c and lower horizontal portions 4d on the periphery 4a. A hinge shaft 7 is provided on the upper and lower horizontal portions 4c and 4d at a predetermined interval from 4b. That is, in the present embodiment, the hinge shaft 7 has a shape in which the hinge shaft 7 protrudes in the middle of the periphery of the wings 4L, 4R with a space left and right from the diameter line of the cylindrical body 5. The hinge shaft 7 is axially supported by the shaft hole of the cylindrical body 5, and the wing body 4L,
The opening and closing operation of 4R becomes possible. Also, on the contact side 4b,
In order to improve the airtightness when the ventilation register is closed, the overlapping portion 8 is provided so that the contact sides 4b of the wing body 4L and the wing body 4R overlap each other.

Similarly to the overlapping section 8, a sealing plate 9 is provided at the lower horizontal portion 4d of the wing body 4L in order to improve the airtightness when the ventilation register is closed. 9 abuts against the side wall of the recess 5a to prevent the wing body 4 from being excessively opened.

The opening / closing operation of the ventilation register is as follows. When the lever 1 is moved rightward in the closed state shown in FIG.
The operating arm 2 rotates to the left with the fulcrum as a fulcrum, and the connecting arms 3L and 3R locked to the connecting arm locking portion 2b of the operating arm 2 move left while maintaining the positions shown in FIGS. Shift in the direction. Then, in conjunction with this movement, the wing body 4 locked to the connecting arms 3L, 3R.
L and 4R operate independently and simultaneously with the hinge shaft 7 as a fulcrum, and become the open state shown in FIG. In the operation from the open state to the closed state, the operation opposite to the above-described operation is performed by moving the lever 1 to the left, and the state is opened.

[0022]

As described above, according to the present invention, the opening / closing operation can be performed smoothly even after many years of use by using a simple mechanism that eliminates a rotating mechanism portion that easily accumulates fine particles such as gears and screws. While being able to
Since the structure is such that the flow of ventilation of the ventilation opening is not easily obstructed, the functionality of the ventilation register can be further enhanced without impairing the original ventilation function of the ventilation opening. In addition, since the open / close state of the ventilation register can be reliably fixed together with a click feeling, ventilation or airtightness can be improved.
