本発明は、取付ネジをネジ穴に螺合させることにより、蓋体及びパッキンをケース本体に固定させ得る防水ケースに関するものである。   The present invention relates to a waterproof case in which a cover body and a packing can be fixed to a case body by screwing attachment screws into screw holes.

一般に、ＡＴＶやバギーなど悪路走行を行う車両においては、ハンドルバーの先端側における把持グリップ近傍にスロットルケースが取り付けられており、該スロットルケースから突出形成されたスロットルを揺動操作することによりエンジンの駆動制御を行うよう構成されている。かかるスロットルケースからは、スロットルと接続されたワイヤケーブルが延設されており、該ワイヤーケーブルの他端をエンジン側に接続して、当該スロットルの揺動操作がエンジン側に伝達され得るようになっていた。   In general, in a vehicle that travels on a rough road such as ATV or buggy, a throttle case is attached in the vicinity of the grip grip on the front end side of the handlebar, and an engine is operated by swinging a throttle that is formed protruding from the throttle case. It is comprised so that drive control may be performed. A wire cable connected to the throttle extends from the throttle case, and the other end of the wire cable is connected to the engine side so that the swing operation of the throttle can be transmitted to the engine side. It was.

また、スロットルケースは、内部に収容空間を有するケース本体と、該ケース本体の開口を塞ぐ蓋体と、該蓋体とケース本体との間に介在して防水を図るパッキンとを有した防水ケースから成り、そこから突出形成されたスロットルの作動部が収容空間内に収容されている。パッキンは、ケース本体の開口縁部に倣った形状とされ、取付ネジにより蓋体をケース本体に取り付けた際、内部の収容空間を密閉して雨水等が内部に浸入しないようになっている。   The throttle case also includes a case main body having a housing space therein, a lid that closes the opening of the case main body, and a packing that is interposed between the lid and the case main body for waterproofing. And a throttle operating portion projecting therefrom is housed in the housing space. The packing has a shape that follows the opening edge of the case main body, and when the lid is attached to the case main body with an attaching screw, the internal accommodation space is sealed so that rainwater or the like does not enter the inside.

上記の如きスロットルケース（防水ケース）を車両に組み付けるには、ケース本体、蓋体及びパッキンを仮止めした取付ネジを一旦緩めて蓋体を取り外し、内部の作動部にエンジンまで延びるワイヤケーブルを接続した後、再び取付ネジを締める作業が行われていた。同スロットルケースによれば、ケース本体と蓋体との間にパッキンが介在するので、内部に雨水等が浸入し、ワイヤケーブルを介してエンジンに至ってしまう不具合を回避することができる。尚、かかる先行技術は、文献公知発明に係るものでないため、記載すべき先行技術文献情報はない。   To attach the throttle case (waterproof case) to the vehicle as described above, loosen the mounting screws that temporarily hold the case body, lid, and packing, remove the lid, and connect the wire cable that extends to the engine to the internal working part. After that, the work of tightening the mounting screw was performed again. According to the throttle case, since the packing is interposed between the case main body and the lid body, it is possible to avoid a problem that rainwater or the like enters the inside and reaches the engine via the wire cable. In addition, since this prior art does not relate to the literature known invention, there is no prior art document information to be described.

以下、本発明の実施形態について図面を参照しながら具体的に説明する。
本実施形態に係る防水ケースは、ＡＴＶなどのハンドルバーに取り付けられたスロットルケースから成り、図１乃至図３に示すように、スロットル３が突出形成されたケース本体１と、ケース本体１に固定される蓋体２と、ケース本体１と蓋体２との間に介在したシール部材としてのパッキン９とから主に構成されている。 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The waterproof case according to the present embodiment is composed of a throttle case attached to a handlebar such as ATV. As shown in FIGS. 1 to 3, the case main body 1 is formed with a throttle 3 protruding, and is fixed to the case main body 1. The main body is mainly composed of a lid body 2 and a packing 9 as a seal member interposed between the case main body 1 and the lid body 2.

ケース本体１は、内部にスロットル３の作動部７を収容するとともに、当該作動部７を取り付けるべく図１中上方に開口したものである。また、ケース本体１に形成されたスロットル３は、その先端側（不図示）が運転者による押圧操作を可能とした形状とされるとともに、押圧操作により回動軸６を中心として回転可能とされている。然るに、ケース本体１の開口縁部１ａは、図２で示すような形状とされ、その所定箇所にはネジ穴ｎｃが形成されている。かかるネジ穴ｎｃは、後述する取付ネジＮと螺合する雌ネジ形状が内周面に形成されている。   The case body 1 accommodates the operating portion 7 of the throttle 3 therein, and is opened upward in FIG. 1 to attach the operating portion 7. The throttle 3 formed in the case body 1 has a tip end (not shown) having a shape that can be pressed by the driver, and can be rotated around the rotation shaft 6 by the pressing operation. ing. However, the opening edge 1a of the case body 1 has a shape as shown in FIG. 2, and a screw hole nc is formed at a predetermined position. The screw hole nc is formed on the inner peripheral surface with a female screw shape to be screwed with a mounting screw N described later.

尚、ケース本体１には、車両のハンドルバーＨの外周形状に略合致した円弧形状を有した取付部４が配設されており、該取付部４にてハンドルバーＨを挟み込みつつ締付ネジ５を締め付けることにより、ケース本体１をハンドルバーＨに固定させ得るよう構成されている。   The case body 1 is provided with a mounting portion 4 having an arc shape that substantially matches the outer peripheral shape of the handlebar H of the vehicle, and a tightening screw while sandwiching the handlebar H at the mounting portion 4. The case body 1 is configured to be fixed to the handle bar H by tightening 5.

作動部７は、回動軸６に固定されスロットル３の操作に応じて回動し得るものであり、その先端側には車両側から延設されたワイヤケーブルＫ（図２及び図３参照）のワイヤ（不図示のプッシュプルワイヤ）と接続し得る接続部７ａが形成されている。これにより、スロットル３の操作に伴って作動部７が回動する（図２中２点鎖線で示した状態になる）と、ワイヤケーブルＫ内のワイヤを引っ張り、車両のエンジンを制御（スロットル弁の開閉）することが可能となっている。   The actuating portion 7 is fixed to the rotating shaft 6 and can be rotated in accordance with the operation of the throttle 3, and a wire cable K extending from the vehicle side at the distal end thereof (see FIGS. 2 and 3). A connecting portion 7a that can be connected to the other wire (not shown push-pull wire) is formed. As a result, when the operating portion 7 is rotated in accordance with the operation of the throttle 3 (a state indicated by a two-dot chain line in FIG. 2), the wire in the wire cable K is pulled to control the vehicle engine (throttle valve). Can be opened and closed).

尚、ケース本体１の所定部位には、ワイヤケーブルＫ先端に形成された防水部材（不図示）を嵌め込むための挿通孔２ｂが形成されている。しかして、挿通孔２ｂは、不図示の防水部材により塞がれ、内部の収容空間Ｓにおける密閉が保たれた状態とされている。また、作動部７には、ねじりコイルバネ８の一端が接続されており、当該作動部７を常時初期状態とする方向に付勢している。   An insertion hole 2b for fitting a waterproof member (not shown) formed at the tip of the wire cable K is formed at a predetermined portion of the case body 1. Therefore, the insertion hole 2b is closed by a waterproof member (not shown) and is kept in a sealed state in the internal storage space S. In addition, one end of a torsion coil spring 8 is connected to the operating portion 7 and biases the operating portion 7 in a direction that always sets the operating portion 7 in an initial state.

蓋体２は、ケース本体１の開口を塞ぎ、内部に作動部７等の部品を収容する収容空間Ｓを形成するためのもので、図３に示すように、前述したネジ穴ｎｃと対応した位置には取付ネジＮを挿通するためのネジ挿通孔ｎａが形成されている。この取付ネジＮは、図６に示すように、そのネジ山部Ｎａの外径（ネジ山頂部までの寸法）が寸法Ｄとされたもので、ネジ挿通孔ｎａの内径寸法ｄ１（図５参照）は、寸法Ｄより若干大きく形成されている。   The lid 2 is for closing the opening of the case main body 1 and forming an accommodating space S for accommodating components such as the operating portion 7 therein, and corresponds to the screw hole nc described above as shown in FIG. A screw insertion hole na for inserting the attachment screw N is formed at the position. As shown in FIG. 6, the mounting screw N has an outer diameter (dimension to the top of the screw thread) of the screw thread portion Na as a dimension D, and an inner diameter dimension d1 of the screw insertion hole na (see FIG. 5). ) Is formed slightly larger than the dimension D.

パッキン９は、図４に示すように、ケース本体１の開口縁部１ａの形状に倣って形成され、蓋体２とケース本体１との間に介在して収容空間Ｓを密閉するためのもので、前述したネジ穴ｎｃ及びネジ挿通孔ｎａと対応した位置にはネジ挿通孔ｎｂが形成されている。これにより、取付ネジＮをネジ挿通孔ｎａ及びｎｂに挿通させつつネジ穴ｎｃに螺合させれば、蓋体２及びパッキン９をケース本体１に固定させることができる。   As shown in FIG. 4, the packing 9 is formed following the shape of the opening edge 1 a of the case body 1, and is interposed between the lid 2 and the case body 1 to seal the accommodation space S. Thus, screw insertion holes nb are formed at positions corresponding to the screw holes nc and screw insertion holes na described above. Accordingly, the lid body 2 and the packing 9 can be fixed to the case body 1 by inserting the attachment screw N through the screw insertion holes na and nb and screwing them into the screw holes nc.

ここで、本実施形態に係るパッキン９のネジ挿通孔ｎｂは、その内径寸法ｄ２（図５参照）が取付ネジＮにおけるネジ山部Ｎａの外径Ｄより若干小さく（谷径よりは大きい）設定され、挿通した取付ネジＮのネジ山と嵌合し得るようになっている。これにより、図７に示すように、取付ネジＮを緩め、蓋体２及びパッキン９をケース本体１から取り外した際、パッキン９のネジ挿通孔ｎｂが取付ネジＮのネジ山と嵌合した状態が維持されるようになっている。   Here, the screw insertion hole nb of the packing 9 according to the present embodiment is set such that the inner diameter dimension d2 (see FIG. 5) is slightly smaller than the outer diameter D of the threaded portion Na of the mounting screw N (larger than the valley diameter). Thus, it can be fitted to the thread of the inserted mounting screw N. Accordingly, as shown in FIG. 7, when the mounting screw N is loosened and the lid 2 and the packing 9 are removed from the case body 1, the screw insertion hole nb of the packing 9 is fitted to the thread of the mounting screw N. Is to be maintained.

即ち、本スロットルケースをＡＴＶなどの車両に組み付けるべく、取付ネジＮを緩め、蓋体２及びパッキン９を一時的に取り外して作動部７の接続部７ａにワイヤを接続する作業を行う際、ネジ穴ｎｃとの螺合が解除された取付ネジＮはネジ挿通孔ｎｂとの嵌合が維持される（図７の状態となる）ため、蓋体２からの離脱が回避され、組み付け時の作業性を向上することができるのである。   That is, in order to assemble the throttle case to a vehicle such as an ATV, the screw N is loosened, the lid 2 and the packing 9 are temporarily removed, and the wire is connected to the connecting portion 7a of the operating portion 7 when performing the work. Since the mounting screw N, which has been unscrewed from the hole nc, is kept in engagement with the screw insertion hole nb (becomes the state shown in FIG. 7), detachment from the lid 2 is avoided, and assembly work is performed. It is possible to improve the property.

更に、図５に示すように、パッキン９のネジ挿通孔ｎｂの周縁部９ａは、他の部位より薄肉とされ、当該周縁部９ａとケース本体１との間にクリアランスＣＬが形成されている。これにより、一時的に取り外した蓋体２及びパッキン９を再びケース本体１に取り付けるべく、取付ネジＮを蓋体２及びパッキン９のネジ挿通孔ｎａ、ｎｂに挿通させてケース本体１のネジ穴ｎｃに螺合させる際、図８に示すように、当該取付ネジＮのネジ山に嵌合したパッキン９のネジ挿通孔ｎｂ周縁部９ａがケース本体１との間のクリアランスＣＬ内で変形され得るので、当該周縁部９ａがネジ穴ｎｃ内に巻き込まれてしまうのを回避することができる。   Further, as shown in FIG. 5, the peripheral portion 9 a of the screw insertion hole nb of the packing 9 is thinner than other portions, and a clearance CL is formed between the peripheral portion 9 a and the case body 1. As a result, in order to reattach the lid 2 and the packing 9 temporarily removed to the case body 1, the mounting screws N are inserted into the screw insertion holes na and nb of the lid 2 and the packing 9 and screw holes in the case body 1. When screwing into the nc, as shown in FIG. 8, the screw insertion hole nb peripheral portion 9 a of the packing 9 fitted to the thread of the mounting screw N can be deformed within the clearance CL between the case body 1 and the screw 9. Therefore, it is possible to avoid the peripheral edge 9a from being caught in the screw hole nc.

上記スロットルケースによれば、蓋体２とケース本体１との間に介在するパッキン９により防水が図られているので、内部に雨水等が浸入し、ワイヤケーブルＫを介してエンジンに至ってしまう不具合を回避することができる。また、上述の如く、一時的に緩めた取付ネジＮが蓋体２から離脱してしまうのを回避でき、組み付け時の作業性を向上することができるとともに、取付ネジＮのネジ山にネジ挿通孔ｎｂが嵌合しているので、両者の密着性を高めることとなり、防水性能を更に向上させることができる。   According to the throttle case, since waterproofing is achieved by the packing 9 interposed between the lid body 2 and the case body 1, rainwater or the like enters the inside and reaches the engine via the wire cable K. Can be avoided. Further, as described above, the temporarily loosened mounting screw N can be prevented from being detached from the lid 2, and the workability at the time of assembly can be improved, and the screw thread of the mounting screw N can be inserted. Since the hole nb is fitted, the adhesion between the two is enhanced, and the waterproof performance can be further improved.

尚、上記本実施形態によれば、ＡＴＶなどの車両への組み付け時にワイヤケーブルＫとの接続作業が必要なスロットルケースに適用しているので、当該スロットルケースの防水性を確実に確保しつつ車両への組み付け作業における作業性を向上させることができる。   Incidentally, according to the present embodiment, since the present invention is applied to a throttle case that requires connection work with the wire cable K at the time of assembling the ATV or the like to the vehicle, the vehicle is secured while ensuring the waterproofness of the throttle case. Workability in the assembly work can be improved.

以上、本実施形態について説明したが、本発明はこれに限定されるものではなく、例えばケース本体の内部に種々部品を収容し、蓋体及びパッキンにて開口を塞いで収容空間を密閉し得る防水ケースであれば、他のもの（内部に電子部品等を収容した防水ケース等）にも適用することができる。即ち、内部への雨水等の浸入を防止するためのパッキンが介在し、当該パッキンのネジ挿通孔が取付ネジのネジ山と嵌合し得る構成であれば、ＡＴＶ等のスロットルケースに限らず、広く適用することができるのである。   As mentioned above, although this embodiment was described, this invention is not limited to this, For example, various components are accommodated in the inside of a case main body, and an opening can be closed with a cover body and packing, and an accommodation space can be sealed. As long as it is a waterproof case, it can also be applied to other cases (such as a waterproof case in which an electronic component or the like is accommodated). That is, as long as a packing for preventing intrusion of rainwater or the like inside is interposed and the screw insertion hole of the packing can be fitted to the thread of the mounting screw, it is not limited to a throttle case such as ATV, It can be widely applied.

パッキンに形成されたネジ挿通孔が、挿通された取付ネジのネジ山と嵌合し得る防水ケースであれば、外観形状が異なるもの或いは他の機能が付加されたものにも適用することができる。   If the screw insertion hole formed in the packing is a waterproof case that can be fitted with the thread of the inserted mounting screw, it can be applied to a case with a different external shape or with other functions added. .
