Description

本発明は、電気錠用錠箱の防水構造に関する。 The present invention relates to a waterproof structure for an electric lock box.

特許文献１には、「前面を開口部６とした角形の収納用箱体１と、この収納用箱体１の前面を覆う前板部１２ａに屋根板部１２ｂを続かせた断面逆Ｌ形の主カバー部１２を有する覆蓋体１１から成り、前記覆蓋体１１を収納用箱体１に対して前記主カバー部１２で収納用箱体１の上面から前面にわたる部分が覆われるように被せて施蓋するようにした電気機器収納用箱」が開示されている（符号は特許文献１のもの）。 Patent Document 1 states that “a square storage box 1 having an opening 6 on the front surface, and a front plate portion 12 a covering the front surface of the storage box 1 with a roof plate portion 12 b connected to an inverted L-shaped cross section. The cover 11 is covered with the main cover 12 so that the main cover 12 covers the portion from the upper surface to the front of the storage box 1. An electric device storage box that is covered is disclosed (the reference numeral is that of Patent Document 1).

そして、この特許文献１には、さらに、覆蓋体１１の主カバーの上壁１２ｂの下面と箱体１の天板部４の上面との間に間隙Ｓができるように、前記天板部４を屋根の如くやや傾斜状に形成する旨が図面（例えば図３）と共に記載されている（段落０００８）。 And in this patent document 1, the said top-plate part 4 is further provided so that the clearance gap S may be formed between the lower surface of the upper wall 12b of the main cover of the cover body 11, and the upper surface of the top-plate part 4 of the box 1. FIG. Is described with a drawing (for example, FIG. 3) (paragraph 0008).

したがって、特許文献１の電気機器収納用箱は、接合部を全溶接する必要もなく、また、特殊なシール処理を天板部４に施す必要もないという利点がある。 Therefore, the electric equipment storage box of Patent Document 1 has an advantage that it is not necessary to weld all the joint portions and it is not necessary to apply a special sealing process to the top plate portion 4.

しかしながら、特許文献１には、箱体の防水構造を電気錠用錠箱に適用できる旨の記載や示唆がなく、また、特許文献１の防水構造では、覆蓋体１１が断面逆Ｌ形に形成されており、かつ一側開口の箱体の上面から前面にわたる部分を全て覆う構造体であることから、扉に対する錠箱の取付け面、コスト面、体裁面、覆蓋体１１の装着面等を考慮すると、そのまま電気錠用錠箱に適用するには不向きであるという問題点がある。
特開平１０−１９０２４８号公報 However, Patent Document 1 does not have any description or suggestion that the waterproof structure of the box can be applied to the lock box for an electric lock. In the waterproof structure of Patent Document 1, the cover 11 is formed in an inverted L-shaped cross section. Since it is a structure that covers the entire area from the top surface to the front surface of the box with one side opening, the mounting surface of the lock box with respect to the door, the cost surface, the appearance surface, the mounting surface of the cover body 11 and the like are considered. Then, there exists a problem that it is unsuitable for applying to an electric lock box as it is.

そこで、まず、図１乃至図３を参照にして、電気錠用錠箱Ｘ（以下、「錠箱Ｘ」という。）の構成を簡単に説明する。１はケース身、２はケース蓋、３はフロント用の前板、４はフロントである。ケース身１又はケース蓋２の形状は任意に設計することができるが、普通一般に、ケース身１は、図１で示すように、手前側の幅広側面が矩形状に開口５した角型ケース枠体となっており、ケース蓋２はこの開口５を閉鎖する。 First, the configuration of the electric lock box X (hereinafter referred to as “lock box X”) will be briefly described with reference to FIGS. 1 to 3. Reference numeral 1 denotes a case body, 2 a case lid, 3 a front plate for the front, and 4 a front. Although the shape of the case body 1 or the case lid 2 can be designed arbitrarily, generally, the case body 1 generally has a rectangular case frame with a wide open side 5 on the front side as shown in FIG. The case lid 2 closes the opening 5.

ここで説明の便宜上、電気錠の各構成部材を収納するケース身１の各壁に符号を付す。なお、底壁、前板の下部、後壁の下部等の細部的事項は省略してある。
符号６はケース身１の幅広側壁で、この幅広側壁６は矩形板状のケース蓋２と対向する。７はケース身１の後壁で、この後壁７は幅広側壁６の端部を直角に折り曲げて形成されている。そして、８がケース身１の上壁である。 Here, for convenience of explanation, reference numerals are given to the respective walls of the case body 1 for housing the constituent members of the electric lock. Detailed items such as the bottom wall, the lower part of the front plate, and the lower part of the rear wall are omitted.
Reference numeral 6 denotes a wide side wall of the case body 1, and the wide side wall 6 faces the case lid 2 having a rectangular plate shape. Reference numeral 7 denotes a rear wall of the case body 1, and the rear wall 7 is formed by bending the end of the wide side wall 6 at a right angle. Reference numeral 8 denotes an upper wall of the case body 1.

本実施例では、この上壁８の先端部に前板３の内壁面３ａに至る切欠状の開口部分９を形成し、この開口部分９に屋根部分を有する弾性防水片Ｙが密閉状態に嵌め込まれる。 In this embodiment, a notch-shaped opening portion 9 reaching the inner wall surface 3a of the front plate 3 is formed at the tip of the upper wall 8, and an elastic waterproof piece Y having a roof portion is fitted into the opening portion 9 in a sealed state. It is.

ところで、前記開口部分９の形状は、図２及び図３で示すように、実施例ではケース身１の幅広側壁６の内側縁６ａ、ケース身２の内側縁２ａ、前板３の内壁面３ａ及び該内壁面３ａと対向する開口部分９の切欠端面９ａにより平面視矩形状に画定されているが、上壁８の切欠態様によっては、その大きさや形状は任意に変わる。したがって、開口部分９の形成部位（上壁８）は別として、その大きさや形状は、発明の本質的事項ではない。 By the way, as shown in FIGS. 2 and 3, the shape of the opening portion 9 is, in the embodiment, the inner edge 6 a of the wide side wall 6 of the case body 1, the inner edge 2 a of the case body 2, and the inner wall surface 3 a of the front plate 3. In addition, it is defined in a rectangular shape in plan view by the cut-out end face 9a of the opening portion 9 facing the inner wall surface 3a. However, depending on the cut-out mode of the upper wall 8, the size and shape are arbitrarily changed. Therefore, apart from the site where the opening 9 is formed (upper wall 8), its size and shape are not essential matters of the invention.

（３）電気錠の構成部材
電気錠の構成部材の詳細は割愛している。図１を参照にして主な部材を説明すると、１１は電装部品、例えばマイクロスイッチで、この電装部品１１は上壁８の先端部の開口部分９の真下に所要空間を有して固定的に配設されている。電装部品１１の詳細説明も割愛するが、電装部品１１は、例えば前板３の内壁面３ａに固定した断面ハット型形状の下部支持部材１２及び幅広側壁６の内壁上部に横設したピン状の上部支持部材１３に支持されている。 (3) Components of the electric lock The details of the components of the electric lock are omitted.

図２は弾性防水片Ｙの斜視図、図１及び図３は弾性防水片Ｙを錠箱Ｘの開口部分９に圧入固定した状態の各概略説明図である。その他の図は、弾性防水片Ｙの平面視、右側面図等である。 (4) Elastic waterproof piece Y
2 is a perspective view of the elastic waterproof piece Y, and FIGS. 1 and 3 are schematic explanatory views showing a state in which the elastic waterproof piece Y is press-fitted and fixed to the opening 9 of the lock box X. FIG. Other figures are a plan view, a right side view, and the like of the elastic waterproof piece Y.

さて、弾性防水片Ｙは、弾性ゴム或いは弾性の合成樹脂材で外観上家型形態に形成されている。図２で示す弾性防水片Ｙの形態は家型形状の一例であり、もちろん、この形状に限定されるものではない。要は、弾性防水片Ｙは、その機能の面から考察すると、（ａ）錠箱Ｘの開口部分９の縁部に密着する密着性、（ｂ）上面或いは頭部の形状が水はけに優れている形状適合性、（ｃ）開口部分９に対する取付けが簡単な装着容易性、（ｄ）そして、安価性等が望まれる。 Now, the elastic waterproofing piece Y is formed in a house-like form from the outside with an elastic rubber or an elastic synthetic resin material. The form of the elastic waterproofing piece Y shown in FIG. 2 is an example of a house shape, and of course is not limited to this shape. In short, considering the function of the elastic waterproofing piece Y, (a) the close contact with the edge of the opening 9 of the lock box X, (b) the shape of the upper surface or head is excellent in draining. Desirable shape conformity, (c) easy attachment to the opening portion 9, (d) and low cost are desired.

（５）弾性防水片Ｙの具体的構成
弾性防水片Ｙは、例えば弾性ゴムで、かつ家型ブロック状に形成され、上壁８の開口部分９に栓的に圧入される。しかして、２１は少なくとも開口部分９の一部と、該開口部分９を形成するケース身１の幅広側壁６の上辺の内側縁６ａを含む開口上辺一部と、ケース蓋２の内側縁２ａを含む開口上辺一部をそれぞれカバーする屋根部分である。この屋根部分２１の上面は、例えば図５の縦断面を参照にすると、中央頂部ａを基準にして鈍角状態で左右均等に傾斜する傾斜面となっている。もちろん、屋根部分２１の傾斜面は、特に図示しないが、「へ」の字形状、蒲鉾形状或いはアール形状等であっても良い。 (5) Specific configuration of the elastic waterproof piece Y The elastic waterproof piece Y is made of, for example, elastic rubber and is shaped like a house block, and is press-fitted into the opening 9 of the upper wall 8. Thus, 21 includes at least a part of the opening part 9, a part of the opening upper side including the inner edge 6 a of the upper side of the wide side wall 6 of the case body 1 forming the opening part 9, and the inner edge 2 a of the case lid 2. It is the roof part which covers each opening upper side part to include. For example, referring to the longitudinal section of FIG. 5, the upper surface of the roof portion 21 is an inclined surface that is inclined evenly on the left and right in an obtuse angle state with respect to the central apex a. Of course, the inclined surface of the roof portion 21 is not particularly illustrated, but may have a “h” shape, a saddle shape, a round shape, or the like.

また、屋根部分２１の左右の鍔状端部ｂ、ｂは、屋根部分２１に連設する角型圧入部２２の左右の側壁２２ａからそれぞれ突出している。これら鍔状端部ｂ、ｂは、図３で示すように、弾性防水片Ｙを上壁８の開口部分９に圧入すると、前述したケース身１及びケース蓋２の上辺に支持される。 Further, the left and right bowl-shaped end portions b, b of the roof portion 21 protrude from left and right side walls 22 a of the square press-fit portion 22 provided continuously with the roof portion 21. As shown in FIG. 3, these hook-shaped ends b and b are supported on the upper sides of the case body 1 and the case lid 2 when the elastic waterproof piece Y is press-fitted into the opening 9 of the upper wall 8.

次に、本実施例の弾性防水片Ｙは、例えば屋根部分２１及び角型圧入部２２の前面に連設する（続く）垂直状態の前板部分２３を有している。この前板部分２３の下部側（鍔状端部ｂの下面を基準）は、開口部分９の前方側を塞ぐ、一方、前板部分２３の上部側（屋根部分２１に続く部分）は、開口部分９或いは錠箱Ｘの上壁８から突出する。 Next, the elastic waterproofing piece Y of the present embodiment has a front plate portion 23 in a vertical state that is continuously provided on the front surface of the roof portion 21 and the square press-fit portion 22, for example. The lower side of the front plate portion 23 (based on the lower surface of the bowl-shaped end b) closes the front side of the opening portion 9, while the upper side of the front plate portion 23 (the portion following the roof portion 21) is open. It protrudes from the upper wall 8 of the part 9 or the lock box X.

しかして、弾性防水片Ｙを開口部分９に強制的に嵌め込むと、圧入部２２の左右の側壁２２ａは、図３で示すように開口部分９に嵌入すると同時に錠箱Ｘの内面に密着状態に圧接する。そして、圧入部２２が所定位置まで入り込むと、傾斜状の屋根部分２１は、その左右の鍔部ｂがケース身１及びケース蓋２の開口縁の上辺に支持されることから、錠箱Ｘの開口部分９或いは上壁８から突出する。また、図１で示すように、前板部分２３の前面２３ａは、錠箱Ｘの前板３の内面３ａに面接触状態に密着する。 Thus, when the elastic waterproof piece Y is forcibly fitted into the opening portion 9, the left and right side walls 22a of the press-fit portion 22 are fitted into the opening portion 9 as shown in FIG. Press contact. Then, when the press-fit portion 22 enters to a predetermined position, the inclined roof portion 21 is supported by the upper side of the opening edge of the case body 1 and the case lid 2 of the right and left collar portions b. It protrudes from the opening portion 9 or the upper wall 8. Further, as shown in FIG. 1, the front surface 23 a of the front plate portion 23 is in close contact with the inner surface 3 a of the front plate 3 of the lock box X in a surface contact state.

ところで、本実施例の弾性防水片Ｙは、圧入される下端部（例えば角型圧入部２２）にケース身１の幅広側壁６と直交する上部支持部材１３用の下向切欠２４を有している。また、配線手段１４が嵌り合う第２の下向切欠２５が錠箱Ｘの前板３と交差する方向に有している。これらの下向切欠２４、２５は、電装部品１１の配設位置を考慮したものであるから、本発明の所期の目的との関係では、発明の本質的事項ではない。 By the way, the elastic waterproofing piece Y of the present embodiment has a downward notch 24 for the upper support member 13 orthogonal to the wide side wall 6 of the case body 1 at the lower end portion (for example, the square press-fit portion 22) to be press-fitted. Yes. Further, a second downward notch 25 in which the wiring means 14 is fitted has a direction intersecting the front plate 3 of the lock box X. Since these downward cutouts 24 and 25 take into consideration the arrangement position of the electrical component 11, they are not essential matters of the invention in relation to the intended purpose of the present invention.

発明の実施の形態で示した第１実施例の弾性防水片Ｙは、ケース身１とケース蓋２とを複数個の固着具を介して一体的に結合した後に、上壁８の先端部側の開口部分９に圧入するものである。 The elastic waterproofing piece Y of the first example shown in the embodiment of the invention is formed by integrally connecting the case body 1 and the case lid 2 via a plurality of fixing tools, and then the front end side of the upper wall 8. It press-fits into the opening part 9 of this.

しかしながら、第２実施例に相当する図７及び図８で示すように、ケース身１Ａとケース蓋２Ｂとを複数個の固着具を介して一体的に結合する際、家型形状の弾性防水片Ｙ１を、該ケース身１Ａとケース蓋２Ｂとの結合によって形成される切欠状の開口部分９Ａの開口縁６ａ、２ａ、９ａ内に、左右の側壁２２ａ等に水平嵌合溝２７を有する圧入部２２Ａを位置付けた上で、該圧入部２２Ａをケース身１Ａとケース蓋２Ｂの前記開口縁６ａ、２ａ、９ａで挟み付けるようにしても良い。 However, as shown in FIG. 7 and FIG. 8 corresponding to the second embodiment, when the case body 1A and the case lid 2B are integrally coupled through a plurality of fasteners, a house-shaped elastic waterproof piece Y1 is a press-fit portion having horizontal fitting grooves 27 on the left and right side walls 22a, etc. in the opening edges 6a, 2a, 9a of the notch-shaped opening portion 9A formed by coupling the case body 1A and the case lid 2B. After positioning 22A, the press-fit portion 22A may be sandwiched between the opening edges 6a, 2a, and 9a of the case body 1A and the case lid 2B.

この第２実施例の錠箱Ｘ１は、少なくとも該ケース身１Ａの上壁８Ａ側の開口縁６ａと、ケース蓋２Ｂの上壁８Ｂ側の開口縁２ａとを弾性防水片Ｙ１の圧入部２２Ａの嵌合溝２７に嵌め込んで密着状態に挟持する必要があることから、錠箱Ｘ１の前記上壁８Ａ、８Ｂは二分割状態となっている。 In the lock box X1 of the second embodiment, at least the opening edge 6a on the upper wall 8A side of the case body 1A and the opening edge 2a on the upper wall 8B side of the case lid 2B are connected to the press-fit portion 22A of the elastic waterproof piece Y1. The upper walls 8A and 8B of the lock box X1 are in a two-divided state because they need to be fitted in the fitting grooves 27 and held in close contact.

したがって、第２実施例の電気錠用錠箱の防水構造は、電装部品１１の少なくとも真上に相当する錠箱Ｘ１の左右の上壁８Ａ、８Ｂに切欠状の開口部分９Ａを形成し、この開口部分を形成する前記上壁８Ａ、８Ｂの対向開口縁６ａ、２ａは、弾性防水片Ｙ１の圧入部２２Ａの左右側壁２２ａの水平嵌合溝２７にそれぞれ密着状態に嵌まり込み、また、該圧入部２２Ａに連設すると共に、前記開口部分の上辺に支持される鍔部ｂを有し、かつその上面が傾斜状或いはアール形状の屋根部分２１は、前記上壁８Ａ、８Ｂから突出していることを特徴とする。 Therefore, the waterproof structure of the lock box for the electric lock according to the second embodiment forms the notch-shaped opening portion 9A on the left and right upper walls 8A and 8B of the lock box X1 corresponding to at least right above the electrical component 11, The opposing opening edges 6a, 2a of the upper walls 8A, 8B forming the opening portions are fitted in close contact with the horizontal fitting grooves 27 of the left and right side walls 22a of the press-fit portion 22A of the elastic waterproof piece Y1, respectively, The roof portion 21 that is provided continuously with the press-fit portion 22A, has a flange portion b supported on the upper side of the opening portion, and has an inclined or rounded upper surface protrudes from the upper walls 8A and 8B. It is characterized by that.

このように構成しても第１実施例と同様に効果がある。なお、この第２実施例に於いて、第１実施例の構成と同一の部分には同一の符号を付して重複する説明を省略する。また、本実施例に於いて、弾性防水片Ｙ、Ｙ１は、錠箱Ｘ、Ｘ１の上壁の一部の開口部分９、９Ａに圧入固定又は挟持固定されているが、もちろん、錠箱Ｘ、Ｘ１内に配設された電装部品１１の位置に対応して上壁の適宜部位に形成された開口部分９、９Ａの一部又は全部に対して栓体として装着される。 Even if comprised in this way, there exists an effect similarly to 1st Example. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted. In this embodiment, the elastic waterproofing pieces Y and Y1 are press-fitted or clamped to a part of the opening portions 9 and 9A of the upper wall of the lock box X and X1, but of course the lock box X , X1 is attached as a plug to a part or all of the opening portions 9 and 9A formed at appropriate portions of the upper wall corresponding to the position of the electrical component 11 disposed in X1.
