取付構造に関する。[Detailed Description of the Invention] This invention relates to a mounting structure for an opening/closing plate in which the opening/closing plate is rotatably attached via a mounting shaft in an opening such as a ventilation hole.
以下、換気箱を例に採つて説明するが、これに
限られるものではない。 The following explanation uses a ventilation box as an example, but the invention is not limited to this.
従来、換気箱における開閉板の取付構造は、例
えば、第４図に示すようなものであつた。 Conventionally, the mounting structure of the opening/closing plate in a ventilation box has been as shown in FIG. 4, for example.
換気箱（開口部）１の両側に設けられた一対の

外側で図例のような金属製の止め輪６を取付軸の
リング溝３ａに嵌着する必要があつた。 Via a mounting shaft 3 that is inserted from one side into a pair of bearings 2 (only one in the example shown) provided on both sides of the ventilation box (opening) 1 and is mounted while being prevented from moving in the insertion direction. An opening/closing plate 5 is attached to the ventilation box 1. At this time, in order to prevent the mounting shaft 3 from moving in the direction opposite to the insertion direction, a metal retaining ring 6 as shown in the illustration is fitted into the ring groove 3a of the mounting shaft outside the ventilation box 1. The need arose.
この取付構造の場合、止め輪６を余分に必要と
するとともに、その嵌着作業も面倒である。 In the case of this mounting structure, an extra retaining ring 6 is required, and the fitting operation thereof is also troublesome.
この考案は、上記にかんがみて、開閉板の取付
作業性が向上し、しかも、部品点数も少なくてす
む開閉板の取付構造を提供することを目的とす
る。 In view of the above, it is an object of this invention to provide an opening/closing plate mounting structure that improves the workability of installing the opening/closing plate and requires fewer parts.

板の取付構造を要旨とする。 This idea allows the opening/closing plate to be installed via a single mounting shaft that is inserted from one side into a pair of bearings provided on both sides of an opening such as a ventilation hole, and is installed with movement in the shaft insertion direction. In the structure in which the mounting shaft is rotatably mounted, the middle part of the mounting shaft is made non-circular in cross section, and the opening/closing plate is held rotatably through the shaft holding part,
The gist of the present invention is a mounting structure for an opening/closing plate in which a detent claw protrudes from a mounting shaft and the claw is engaged with a locking portion formed on the opening/closing plate.
以下、この考案の実施例を、図例に基づいて説
明する。 Hereinafter, embodiments of this invention will be described based on illustrated examples.
第１〜２図に示すように、換気箱１１の開口部
両側には、一対の大径・小径軸受部１２，１３が
形成されている。 As shown in FIGS. 1 and 2, a pair of large-diameter and small-diameter bearing portions 12 and 13 are formed on both sides of the opening of the ventilation box 11.

軸１４は、ABC、PP、ポリアセタール等の剛弾
性を有する合成樹脂材料で一体成形することが望
ましいが、爪１９のみを金属製としてもよい。 The mounting shaft 14 has the above-mentioned pair of large diameter and small diameter bearing parts 1.
2, 13 from one side, the distal end has a small diameter journal 15, the base end has a large diameter journal 16, and an intermediate portion 17 has a non-circular cross section, in the illustrated example, a rectangular cross section. Note that an operating lever 18 is integrally formed on the large diameter journal 16 side. This mounting shaft 14
When assembled into the ventilation box 11, movement in the insertion direction is restrained by a stepped surface formed between the small-diameter journal 15 and the intermediate portion 17. Further, a claw 1 having spring elasticity is provided from the intermediate portion 17.
9 protrudes toward the large-diameter journal 16 side, that is, facing the insertion direction of the mounting shaft. It is preferable that the mounting shaft 14 be integrally molded from a synthetic resin material having rigid elasticity such as ABC, PP, polyacetal, etc., but only the claw 19 may be made of metal.
開閉板２０は、その回転軸線上の両端部に軸保
持部２１，２１が形成されている。軸保持部２１

する。 The opening/closing plate 20 has shaft holding parts 21, 21 formed at both ends thereof on the axis of rotation. Shaft holding part 21
is provided with a non-perfect circular, ie, rectangular, hole into which the intermediate portion 17 of the mounting shaft can be inserted. Further, in the holding part 21a on the side into which the mounting shaft is inserted, when the distal end journal 15 of the mounting shaft is completely inserted into the small diameter bearing part 13, the pawl 19 passes through the holding part 21 while being bent and returns to the inner stage. The size is such that it can be secured to the portion 21a.
上記開閉板２０を換気箱１１に取り付けるに
は、開閉板の軸保持部２１，２１と換気箱の軸受
部１２，１３との軸線が一致するように、開閉板
２０を換気箱１１内に挿入し、続いて、取付軸１
４を換気箱１１の大径軸受部１２側から挿入し、
取付軸の小径ジヤーナル１５を小径軸受部１３を
完全に挿入する。 To attach the opening/closing plate 20 to the ventilation box 11, insert the opening/closing plate 20 into the ventilation box 11 so that the axes of the shaft holding parts 21, 21 of the opening/closing plate and the bearing parts 12, 13 of the ventilation box coincide. Then, install the mounting shaft 1
4 from the large diameter bearing part 12 side of the ventilation box 11,
Completely insert the small diameter bearing part 13 into the small diameter journal 15 of the mounting shaft.

付軸の中間部１７が非真円なので、開閉板２０は
取付軸２１に一体回転可能に保持される。 At this time, the claw 19 of the mounting shaft bends when passing through the holding part 21, but returns to its original state after passing through, and locks on the inner step part 21a of the holding part 21, and also connects the small diameter journal 15 and the intermediate part 17. A locking stepped portion between the two locks the small diameter bearing portion. For this reason, the mounting shaft 21
is prevented from moving in both the insertion direction and the opposite direction, and is fixed to the ventilation box so that it cannot be removed. Further, since the intermediate portion 17 of the mounting shaft is not a perfect circle, the opening/closing plate 20 is held by the mounting shaft 21 so as to be able to rotate integrally therewith.
第３図はこの考案の別の実施例を示し、回転軸
線を開閉板２３の上端にもつていき、かつ、軸保
持部２４を開閉板全長にわたつて形成し、さら

る。なお、２５は換気箱、２６は取付軸である。 FIG. 3 shows another embodiment of this invention, in which the axis of rotation is extended to the upper end of the opening/closing plate 23, the shaft holder 24 is formed over the entire length of the opening/closing plate, and a locking step is provided. This is a locking hole portion 24a. Note that 25 is a ventilation box, and 26 is a mounting shaft.
作用は上記実施例と同様である。 The operation is similar to the above embodiment.
この考案の開閉板の取付構造は、上記のような
構成なので、ワンタツチで取付け可能となり、し
かも止め輪のような余分な部品を必要としない。
従つて、開閉板の取付作業性が向上し、しかも、
部品点数も少なくてすむ等の効果を奏する。 Since the opening/closing plate mounting structure of this invention has the above-described configuration, it can be mounted with one touch, and additional parts such as a retaining ring are not required.
Therefore, the workability of installing the opening/closing plate is improved, and
This has the advantage that the number of parts can be reduced.

A device with a claw (engaging protrusion) is described, but
This engagement protrusion is not engaged with a engagement portion formed on the opening/closing plate as in the present invention, but is engaged directly with the inner wall on one side of the opening. Therefore,
When the opening/closing plate rotates, the pawl of the present invention does not come into sliding contact with the inner wall on one side of the opening, as in the above-mentioned known example, so there is little risk of wear or damage during use, resulting in increased durability. Are better. In addition, in the case of the structure of the present invention, there is no need to provide a gap between the opening/closing plate and the inner walls on both sides of the opening to allow the claws to escape, as in the known example, so the gap between the opening/closing plate and the inner walls on both sides of the opening when closed. can be made as small as possible, and compared to known examples, the opening/closing plate has better sealing performance and less rattling.
