FIG. 2 is a front view showing a state in which pinion gears 4, shutter plates 5 and 5 are attached to a flanged cylinder 2 of the ventilation register R. FIG. 3 shows a cross-sectional view taken along the line XX of FIG.
(About the basic structure of this ventilation register R)
As shown in FIGS. 1 to 3, the ventilation register R is composed of a front plate 1 that can be mostly ventilated and a flanged cylinder 2 that is attached to the front plate 1. A pinion gear 4 is connected to the operation portion 3 projecting from the front plate 1 and a pair of shutter plates 5 and 5 are provided between the front plate 1 and the flange portion 21 of the flanged cylinder 2. A rack 50 that meshes with the pinion gear 4 is provided, and the pair of shutter plates 5 and 5 approach and separate from each other via the pinion gear 4 and the rack 50 by forward and reverse rotation of the operation unit 3.
[0011]
The main components of the ventilation register R will be described below.
(About the configuration of the front plate 1)
As shown in FIGS. 1 and 3, the front plate 1 is formed in a shallow dish shape having a square shape when viewed from the front, and includes a frame body 10, fins 11 extending in the left-right direction in the frame body 10, and a frame body 10 includes a middle rail 12 extending in the vertical direction, an insertion hole 13 disposed in the center of the frame body 10, and a protrusion 14 that maintains an integrated state with the flanged cylinder 2. Here, as shown in FIG. 1 and FIG. 3, the front plate 1 has a large area in which the fins 11 are provided, so that most of the front plate 1 can be ventilated.
(About the configuration of the flanged cylinder 2)
As shown in FIGS. 2 and 3, the flanged cylinder 2 is configured by providing a flange portion 21 that is fixed to the back side of the front plate 1 on one end side of a cylindrical ventilation cylinder 20.
[0012]
As shown in FIGS. 2 and 3, the shutter plates 5 and 5 are fitted into the flange portion 21 so as to approach and separate by a certain range (a range from the position of the two-dot chain line in FIG. 2 to the position of the solid line). A shallow recess 24 that can be moved is provided, and a guide 23 that prevents the shutter plates 5 and 5 from slipping out of the recess 24 and guides the shutter plate 5 when moving is provided.
[0013]
Further, as shown in FIG. 2 and FIG. 3, four side guides 22 for guiding each rack 50 (described later) provided on the shutter plates 5 and 5 are provided on the front surface of the flanged cylinder 2. One vertical guide 27 is provided.
[0014]
Further, as shown in FIGS. 2 and 4, the flanged cylinder 2 includes an outer stopper 25 that restricts the movement of the shutter plates 5 and 5 to the outside by the contact with the end 50 a of the rack 50, and a shutter. An inner stopper 26 is provided for restricting movement of the plates 5 and 5 to the inside by contact with the inner edge of the shutter plate 5.
(About the configuration of the operation unit 3 and the pinion gear 4)
As shown in FIG. 3, the operation unit 3 and the pinion gear 4 are connected via an insertion hole 13, and both are integrated by a set screw 7 so as not to be relatively rotatable.
[0015]
In the attached state shown in FIG. 3, the operation unit 3 is slightly protruded from the front plate 1, and the operator picks up the protruding part and rotates forward and backward.
[0016]
As shown in FIG. 3, the pinion gear 4 is provided with a flange portion 41 on one end surface side of the gear portion 40. In the assembled state as shown in FIG. In a state where it is pressed against the vertical guide 27, it is guided by the horizontal guides 22 and 22 to move.
(About the configuration of the shutter plate 5)
As shown in FIG. 5, the shutter plate 5 has a thin plate shape and is provided with a rack 50 in the vicinity of the inner edge thereof.
[0017]
Here, as shown in FIGS. 6 and 7, the shutter plates 5 and 5 have the rack 50 meshed with the pinion gear 4 at a position that is the same distance from the rotation center of the pinion gear 4. Therefore, the left and right shutter plates 5 and 5 are moved toward and away from each other via the pinion gear 4 by the forward and reverse rotation of the operation unit 3, but the left and right shutter plates 5 and 5 are both at the time of approach and the time of separation. And the distance L to the center of the pinion gear 4 is equal.
[0018]
Further, as shown in FIGS. 4 and 5, ribs 51, 51 are provided on the upper and lower surfaces of the rack 50 in the vicinity of the base end, and these ribs 51, 51 are provided with the lateral guides 22, 22 as shown in FIG. The backlash in the front-rear direction is prevented by abutting against the front and rear.
(Regarding the configuration of the filter 6)
The filter 6 is formed of a resin fiber in a plate shape, and is provided between the rear surface portion of the front plate 1 and the front surface portion of the flanged cylinder 2 as shown in FIG.
(About the excellent action and effect of this ventilation resistor R)
(1). In this ventilation register R, when the operation part 3 protruding from the front plate 1 is picked and rotated, for example, forwardly, the shutter plates 5 and 5 are opened (separated), and the operation part 3 is picked and reversed. When it is rotated, the shutter plates 5 and 5 are closed (approaching). That is, it is not necessary to rotate and adjust the operation unit while paying attention to the eyes as described in the prior art. Further, as described above, the operation unit 3 protruding from the front plate 1 is simply picked and rotated forward and backward.
[0019]
Therefore, in this ventilation register R, the shutter can be fully opened and closed easily from the outside without visual attention.
(2). Most of the front plate 1 can be ventilated, and when the shutter plates 5 and 5 are fully opened, the opening area between them is almost the same as that of the ventilating cylinder 20, so that compared with the conventional one, Ventilation opening area becomes much larger.
(3). An outer stopper 25 for restricting the movement of the shutter plates 5 and 5 to the outside by the contact with the end of the rack 50 is provided, and the movement of the shutter plates 5 and 5 to the inner edge of the shutter plate 5 is further hit. Since the inner stopper 26 that is regulated by the above is provided, it is possible to know whether the shutter plates 50 and 50 are fully opened or completely closed because the operation portion 3 cannot be rotated forward or backward.
[Other Embodiments]
As shown in FIGS. 1 to 3, the ventilation register R of the above embodiment includes a front plate 1 that can be mostly ventilated and a flanged cylinder 2 that is attached to the front plate 1. A pinion gear 4 is connected to an operation portion 3 that protrudes forward from 1, and a pair of shutter plates 5 and 5 are provided between the front plate 1 and the flange portion 21 of the flanged cylinder 2. 5 is provided with a rack 50 that meshes with the pinion gear 4, and the pair of shutter plates 5 and 5 are moved toward and away from each other via the pinion gear 4 and the rack 50 by forward and reverse rotation of the operation unit 3. However, the opening / closing mechanism of the shutter plates 5 and 5 may be as follows.
[0020]
In other words, the opening / closing mechanism of the shutter plates 5 and 5 is configured such that the racks 50 and 50 of the shutter plates 5 and 5 are engaged with the pinion gear 4 connected to the operation unit 3, and the shutter plate is rotated by forward and reverse rotation of the operation unit 3. Any structure may be used as long as 5 and 5 can approach and separate from each other (see FIGS. 6 and 7).
[0021]
【The invention's effect】
Since the present invention is configured as described above, it has the following effects.
[0022]
As is apparent from the contents of the embodiment of the invention, (1) the shutter can be fully opened and closed easily from the outside without visual attention, and (2) the ventilation opening area when the shutter is fully opened. A large ventilation register could be provided.
