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.

For example, as a conventional ventilator grill,
There are some as shown in Figs. 1 is a ventilator grille, 2 is a housing, 3 is a horizontal louver [first louver], 4 is a vertical louver [second louver], 5
is the operating knob. The horizontal louver 3 on the front side (arrow A) adjusts the wind direction in the vertical direction (arrow B) _.
The operating knob 5 attached to the louvers is rotated in the direction of arrow C about the pivot 6, and this movement causes the other horizontal louvers ₃₁ ... ₃₄ to rotate together through the links 7. On the other hand, the vertical louver 4 on the back side (arrow D) is used to adjust the wind direction in the left-right direction (arrow E). 9 mesh with each other, and first operate one of the vertical louvers 4 ₀
rotates around the pivot 10 in a direction (arrow F) intersecting the horizontal louver 3, and the other vertical louvers ₄₁
......4 ₄ follows via link 11. The operating knob 5 consists of an operating knob upper 5 _a and an operating knob lower 5 _b (Fig. 4), and serves as a connecting element by bearing bodies 12 _a and 12 _b formed on the operating knob upper 5 _a and the operating knob lower 5 _b , respectively. A rack 8 is rotatably supported.
13 is an engaging pawl, which is a pawl 14 at the bottom of the pinion 9.
and the operating vertical louver ₄₀ , and functions to always keep the rack 8 horizontal no matter what angle the operating horizontal louver ₃₀ is in, and to ensure reliable engagement with the pinion 9. be. Note that 15 is a grill outlet.

However, in the case of such a conventional ventilator grille 1, since the operation knob 5 and the rack 8, which is a connecting element, are each made of separate parts, the number of parts is correspondingly large.
The assembly of the pinion 9 and the pinion 9 was also relatively troublesome. Furthermore, in the case of the ventilator grille 1 that adjusts the wind direction vertically and _horizontally , both the vertical and 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 part of the horizontal louver 3 in order to perform the operation 4.
The lateral louver 3 inevitably flutters at the frontmost side, causing problems in appearance quality or operability.

This invention has been 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,
Moreover, the purpose is to eliminate the above-mentioned problems by making the overall structure rational.

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. It should be noted that portions similar to those of the prior art are designated by the same reference numerals in the drawings, and redundant explanation will be omitted.

FIGS. 5 to 7 are diagrams showing an embodiment of the present invention. Incidentally, although this invention does not specifically ask about the engagement structure between the operating knob and the first louver,
In this embodiment, this fastening structure is also streamlined with the intention of further reducing the number of parts. First, the configuration will be explained. A through hole 22 for passing and sliding the operating knob 21 is formed in the operation horizontal louver ₂₀₀ of the horizontal louver (first louver) 20 on the front side (arrow A). The operating nozzle 21 and the chain ring 23 as a connecting element are integrally molded via a thin hinge 24, and the operating nozzle 21 can freely slide in the longitudinal direction (arrow E) of the operating lateral louver ₂₀₀ within the through hole 22. Attaching claw 25
_a and 25 _b are provided. And this locking claw 25
_a , 25 _b together with the step 27 provided on the knob 26 of the operation knob 21, the opening end surfaces 2 of the through hole 22
8 and 29. Each horizontal louver 21 including the operation horizontal louver _200
1 ......20 The rotation center 30 of ₄ is the grill outlet 1
It is set to the nearest side of 5. Also, the chain ring [connecting element] 23 and the vertical louver [second louver] 31, specifically the chain ring 32 of the operation vertical louver ₃₁₀ ,
and are chained together so that they can move vertically (arrow B) freely,
This is to convert the sliding of the operating knob ₂₁ in the direction of arrow E into the rotation of the vertical operating louver ₃₁₀ in the direction of arrow F while absorbing the vertical movement of the rear side of the horizontal operating louver 200.
The horizontal louvers 20 ₀ . _. . _{20 4} and the vertical louvers 31 0 .

Next, the action will be explained.

The operation horizontal louver ₂₀₀ and the operation knob 21 are indicated by arrow G.
Since the rotation of the operation knob 2 is integral, the operation knob 2
When 1 is directly rotated in the direction of arrow G about the pivot 30, each horizontal louver ₂₀₀ ...
... ₂₀₄ 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 the center of rotation at the frontmost side of the grill outlet 15, the horizontal louver 20
The front side of 0 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 rear side of the operation horizontal louver ₂₀₀ moves up and down together with the rear side of the operation knob 21. This vertical movement is achieved by the fact that the chain ring 23 as a connecting element and the operation knob 21 are integrally molded with a thin hinge 24, and the chain ring 32 of the vertical operation louver ₃₁₀ and the chain ring 23 as a connecting element
It is absorbed at the bond (chain bond) with. On the other hand, the operation knob 21 is located inside the through hole 22 and the horizontal louver 20
Since it is slidable in the longitudinal direction (arrow E), this movement is transmitted to the chain ring 23, which is a connecting element that slides integrally, and the operation vertical louver ₃₁₀ is operated via the chain ring 32 that is chain-coupled with this. It rotates around the pivot 10 in a direction intersecting the horizontal louver 20 (arrow F), and adjusts the wind direction in the left-right direction (arrow E).

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. Of course, it is free to provide a horizontal louver as a side louver, and this can be easily realized by tilting the above structure and rotating it 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.
Since the front side of the first louver does not flap at all under any condition, the appearance quality is always maintained at a high level, and the operability is also good.

In addition, by devising the engagement between the operation side louver and the operation knob 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.
