Abstract

PURPOSE:To reduce the number of component parts and man-hours for assembling by a structure wherein an operating knob to operate the louver of the grill and a connecting element are integrally molded through a thin hinge. CONSTITUTION:The operating knob 21 and a chain ring 23 serving as the connecting element are integrally molded through the thin hinge 24. When the operating knob 21 is rotated directly about pivots 30 in the direction indicated by the arrow G, horizontal louvers 200-204 are rotated cooperatively, resulting in performing the vertical adjustment of wind direction B. Furthermore, the innermost side of the horizontal louver 200 is vertically moved together with the innermost side of the operating knob 21 so as to rotate a vertical louver 310 through the chain ring 23 and the chain ring 32 of the vertical louver 31 with rotating center at pivots 10 in the direction F, which intersects the direction G of movement of the horizontal louver 20, resulting in performing the horizontal adjustment of wind direction E.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilator grill, and particularly to an improvement in a ventilator grill whose blowing direction can be changed horizontally, vertically, and horizontally.

Examples of conventional ventilator grills are shown in Figures 1 to 4.
There is something like the one shown in the figure. 1 is the ventilator grill,
2 is a housing, 3 is a horizontal louver (first louver), 4 is a vertical louver (second louver), and 5 is an operation knob. Front side (
The horizontal louver 3 at arrow A) is used to adjust the wind direction in the downward direction (arrow B). It is rotated about the pivot 6 in the direction of arrow C, and this movement causes the other horizontal louvers 31 . . . 3÷ to rotate together via the link 7. On the other hand, the vertical louver 4 on the back side (arrow D) is for adjusting the wind direction in the left and right direction (arrow E), and the operation knob 5
By sliding in the direction of arrow E, the rack [connecting element] 8
and the pinion 9 mesh with each other, and first, one operating vertical looper 4o of the vertical louver 4 rotates about the pivot 1° in a direction (arrow F) intersecting the transfer louver 3, and then the other vertical louver 41
... 44 follows via the link 11. The operating knob 5 is composed of an operating knob upper 5a and an operating knob lower 5b (FIG. 4), and bearing bodies 12 are formed on the operating knob upper 5a and the operating knob lower 5b, respectively. ,1
21), the rack 8, which is a connecting element, is rotatably supported. Reference numeral 13 denotes an engaging pawl, which is engaged between the pawl 14 at the bottom of the binion 9 and the operating vertical louver 4o, and keeps the rack 8 horizontal no matter what angle the operating right louver 3o is in. It functions to ensure reliable engagement. Note that 15 is a grill outlet.

However, in such a conventional ventilator grill 1, the operating knob 5 and the connecting element rank 8 are each made of separate parts, so the number of parts is correspondingly large. The assembly was also relatively troublesome. Furthermore, a pair of pencils for adjusting the wind direction vertically, horizontally, and horizontally; in the case of the Taglil 1, the vertical, horizontal louvers 3, Conventionally, it has been thought that it is essential to set the rotation center 6 of the horizontal louver 3 at the innermost position of the horizontal louver 3 in order to perform the operation 4, and for this reason, the horizontal louver 3 inevitably flutters at the closest side. In particular, problems have arisen in terms of appearance quality or operability.

This invention was made by focusing on such conventional problems, and it is possible to set the rotation center of the first louver at the frontmost side of the grill outlet, and the overall structure is streamlined. The purpose of this is to eliminate the above-mentioned problems.

With this intention in mind, the present invention aims to reduce the number of parts by integrally molding the operating knob and the connecting element via a thin hinge, and also sets the rotation center of the first louver at the frontmost side of the grill outlet. , and therefore, in order to be able to convert the slide of the operation knob into rotation of the second louver while absorbing the movement of the rear side of the first louver that moves up and down, the connecting element and the second louver are connected to each other in the first direction. The louver is characterized by a chain connection that absorbs the rotation of the louver.

The present invention will be explained below based on illustrated embodiments. still,
Parts that are the same as those in the past are designated by the same reference numerals in the figure, and repeated explanations are omitted.

Section 5 1 to Section 7M are diagrams showing one embodiment of the present invention. Although this invention does not particularly concern the engagement structure between the operation knob and the first louver, in this embodiment, this engagement structure has been designed with the intention of further reducing the number of parts. We are also trying to streamline the process. First, the configuration will be explained.

Horizontal louver [・first louver] 20 on the front side (arrow A)
The operating right louver 20o is provided with a through hole 22 for passing the operating knob 210 and for sliding. The operation knob 21 and the chain @ 23 as a connecting element are integrally molded via a thin hinge 24, and the operation knob 21 can be freely operated within the through hole 22 by sliding in the longitudinal direction (arrow E) of the louver 20o. The locking molds 25a and 25b are provided so that the locking molds 25a and 25b can be used together with the step 27 provided on the knob portion 26 of the operating knob 21 to open the through hole 3i.
It extends so as to engage with both opening end surfaces 2B and 29 of the η hole 22.

Each horizontal louver 201...2 including the operation right louver 20o
04's rotation center 301d is set at the frontmost side of the grill outlet 15. Also, the hammer ring [connecting element] 23 and the vertical louver [
The second louver] 31, specifically, the silver ring 32 of the operating vertical louver 31o, are chained to each other so that they can move vertically (as indicated by arrow B), and can be operated while absorbing the vertical movement of the east side of the operating right louver 20o. The slide of the knob 21 as indicated by the arrow E is converted into the rotation of the vertical operating louver 31o as indicated by the arrow F. In addition, each horizontal louver 20o...20 rows, and each vertical looper 31g.
...314 is a link 3 connected by a resin hinge etc.
3 and 34, they are jointly freely available.

Next, the action will be explained.

Since the operation right louver 20o and the operation knob 21 are integral when rotating in the direction of the arrow G, when the operation knob 21 is directly rotated in the direction of the arrow G about the pivot 30, each side is rotated through the link 33. The louvers 20o...20♦ rotate together to adjust the wind direction in the vertical direction (arrow B).

At this time, since the horizontal louver 20 is provided with a pivot 30 serving as a rotation center at the frontmost side of the grill outlet 15, the front side of the horizontal louver 20 does not move at all. This is one of the major features of the operation of this invention. By the way, due to this rotation, the operation knob 21 is on the back side of the operation horizontal louver 20°.
The entire back side moves up and down. This vertical movement is achieved by the fact that the connecting element, the silver ring, and the operating knob 21 are integrally molded with a thin hinge, and the connection between the button ring 32 of the operating vertical louver 31o and the connecting element, the silver ring 23 [chain connection]. ] is absorbed. On the other hand, since the operating knob 21 is located in the through hole 22 and can slide freely in the longitudinal direction (arrow E) of the horizontal louver 20, this movement is transmitted to the silver ring n, which is a connecting element that slides integrally, and is connected to the silver ring n. Operation vertical lever through the combined silver ring 32 ~
The horizontal louver 20 rotates around the pivot 10.
rotate in the direction intersecting (arrow F), and rotate in the left-right direction (arrow E
) wind direction adjustment is performed.

In the above explanation, a horizontal louver was used as the first louver on the front side, and a vertical louver was used as the second louver on the back side. It is theoretically possible to provide a horizontal louver as a secondary structure, and it can be easily realized by rotating the above structure completely by 90 degrees, and the same effect can be obtained.

As explained above, according to the present invention, since the structure is as described above, the number of parts and the number of assembly steps can be reduced, management of parts becomes easier, and manufacturing costs can be reduced. With this configuration, the center of rotation of the first louver on the front side can be set at the frontmost side of the grill outlet, so the front side of the first louver will not flap at all no matter what condition it is in, so the appearance The quality is always maintained high and the operability is also good.

In addition, if the engagement between the operating device louver and the operating knob is modified as in the embodiment, in addition to the above effects, the number of parts and assembly man-hours can be further reduced. Another advantage is that links connecting the horizontal louvers, which had to be separately molded and assembled, can now be molded integrally via resin hinges.
