Description

本発明は、装置筐体に関するものである。 The present invention relates to an apparatus housing.

設置床面からの設置高さを可変にするために、底壁にレベルフットを装着した装置筐体としては、特許文献１に記載のものが知られている。この従来例において、レベルフットを構成する軸部には調整ネジが形成され、装置フレーム（筐体本体部）にねじ込まれる。軸部を水平回転させると、軸部は筐体本体部から進退し、筐体本体部の設置高さが調整される。
特開平６-２７３８号公報 As an apparatus housing in which a level foot is attached to the bottom wall in order to make the installation height from the installation floor surface variable, the apparatus described in Patent Document 1 is known. In this conventional example, an adjustment screw is formed on the shaft portion constituting the level foot and is screwed into the apparatus frame (housing body portion). When the shaft portion is rotated horizontally, the shaft portion moves forward and backward from the housing body portion, and the installation height of the housing body portion is adjusted.
JP-A-6-2738

しかし、上述した従来例において、軸部の上端は筐体本体部内に飛び出しているために、筐体本体部の製造時に発生し、製造後の清掃で取りきれなかった溶接スパッタ等が搬送時等に移動し、筐体本体部と調整ネジとの隙間に落ち込むことがある。 However, in the above-described conventional example, since the upper end of the shaft portion protrudes into the housing main body, welding spatter that occurs during the manufacturing of the housing main body and cannot be removed by cleaning after the manufacturing is conveyed. May fall into the gap between the housing body and the adjustment screw.

落ち込んだスパッタ等は、調整ネジの調整操作に伴ってネジ山間に挟まるために、以後、調整ネジへの螺合操作が不可能となり、設置高さ調整が全くできなくなる。 The spatter that has fallen is sandwiched between the screw threads in accordance with the adjusting operation of the adjusting screw, so that the screwing operation to the adjusting screw becomes impossible and the installation height cannot be adjusted at all.

本発明は、以上の欠点を解消すべくなされたものであって、スパッタ等の噛み込みを完全に防止できる装置筐体の提供を目的とする。 The present invention has been made to solve the above-described drawbacks, and an object of the present invention is to provide an apparatus housing that can completely prevent spattering and the like.

装置筐体は、筐体本体部１の底壁にレベルフット３を装着して形成される。レベルフット３の筐体本体部１からの飛び出し寸法を調整可能とするために、レベルフット３には雄ネジ部２が形成されており、筐体本体部１にねじ込まれる。 The device housing is formed by attaching the level foot 3 to the bottom wall of the housing body 1. In order to be able to adjust the projecting dimension of the level foot 3 from the housing body 1, the level foot 3 is formed with a male screw portion 2 and screwed into the housing body 1.

薄板体５は全体として可撓性を有するように板厚、材質が決定され、中央部にネジ挿通孔４が開設される。この薄板体５は、筐体本体部１の底壁面、すなわち、レベルフット３の筐体本体部１への進入基端に固定され、レベルフット３は、薄板体５のネジ挿通孔４を貫通して筐体本体部１外に突出する。 The thickness and material of the thin plate member 5 are determined so as to be flexible as a whole, and a screw insertion hole 4 is opened at the center. The thin plate member 5 is fixed to the bottom wall surface of the housing body 1, that is, the proximal end of the level foot 3 entering the housing body 1, and the level foot 3 passes through the screw insertion hole 4 of the thin plate member 5. Then, it protrudes out of the housing body 1.

上記ネジ挿通孔４は、雄ネジ部２の呼び径より小径に形成されており、レベルフット３の雄ネジ部２がねじ込まれると、ネジ挿通孔４の内周縁は雌ネジ部７ａとの噛合領域に侵入してネジ山面に圧接する。ネジ挿通孔４の内周縁がネジ山面に圧接する結果、筐体本体部１側の雌ネジ部７ａとレベルフット３の雄ネジ部２との間の隙間は、筐体本体部１内側から完全に閉塞されることとなり、筐体本体部１内に溶接スパッタ等が残留していても、ネジに噛み込むことがなくなる。 The screw insertion hole 4 is formed to have a smaller diameter than the nominal diameter of the male screw portion 2, and when the male screw portion 2 of the level foot 3 is screwed, the inner peripheral edge of the screw insertion hole 4 is engaged with the female screw portion 7a. Enter the area and press into contact with the thread surface. As a result of the inner peripheral edge of the screw insertion hole 4 being in pressure contact with the screw thread surface, the gap between the female screw portion 7a on the housing body 1 side and the male screw portion 2 of the level foot 3 is from the inside of the housing body 1. Even if welding spatter or the like remains in the housing body 1, the screw is not caught in the screw.

本発明によれば、スパッタ等の噛み込みを完全に防止することができる。 According to the present invention, it is possible to completely prevent biting such as sputtering.

図１に現金取引装置として構成された本発明の実施の形態を示す。現金取引装置は、必要な処理系を収容する筐体本体部１内の底壁からレベルフット３を突設して形成される。 FIG. 1 shows an embodiment of the present invention configured as a cash transaction apparatus. The cash transaction apparatus is formed by projecting a level foot 3 from a bottom wall in a housing body 1 that accommodates a necessary processing system.

筐体本体部１は底壁に接合されるチャンネル材８により補強され、このチャンネル材８の裏面にナット７が溶着される。チャンネル材８には、ナット７の雌ネジ部７ａに連通する透孔８ａが穿孔されるとともに（図３（ｂ）参照）、透孔８ａの上方で、筐体本体部１の底壁面には円形の開口１ａが開設される。 The housing body 1 is reinforced by a channel material 8 joined to the bottom wall, and a nut 7 is welded to the back surface of the channel material 8. The channel member 8 is perforated with a through hole 8a communicating with the female screw portion 7a of the nut 7 (see FIG. 3B), and above the through hole 8a, on the bottom wall surface of the housing body 1 A circular opening 1a is opened.

図２に示すように、レベルフット３は、下端に接地フランジ３ａを備えた杆体であり、上部に形成される雄ネジ部２を上記ナット７にねじ込んで筐体本体部１に装着される。接地フランジ３ａの上部には、レベルフット３に回転操作力を与えるためのナット３ｂが一体形成される。 As shown in FIG. 2, the level foot 3 is a housing having a grounding flange 3 a at the lower end, and is attached to the housing main body 1 by screwing a male screw portion 2 formed at the upper portion into the nut 7. A nut 3b for applying a rotational operation force to the level foot 3 is integrally formed on the upper portion of the ground flange 3a.

雄ネジ部２をナット部７ａにねじ込んだ状態でレベルフット３を水平回転させると、図２（ａ）、（ｄ）に示すように筐体本体部１からの突出距離が変化し、設置床面９からの筐体本体部１の設置高さが調整される。図２（ｄ）に示すように、突出距離を小さくした場合には、レベルフット３の上端部は上記円形の開口１ａから筐体本体部１内に収容される。 When the level foot 3 is rotated horizontally with the male screw portion 2 screwed into the nut portion 7a, the protruding distance from the housing body portion 1 changes as shown in FIGS. The installation height of the housing body 1 from the surface 9 is adjusted. As shown in FIG. 2D, when the protruding distance is reduced, the upper end portion of the level foot 3 is accommodated in the housing main body portion 1 through the circular opening 1a.

５は合成樹脂材をシート状に成形した薄板体を示す。この薄板体５は、図２に示すように、チャンネル材８の上面、すなわち、筐体本体部１内方側の壁面に固定される。固定方法は、適宜の周知手段によることができるが、この実施の形態においては、図３（ａ）に示すように、裏面周縁に貼り付けた粘着テープ５ａが使用される。 Reference numeral 5 denotes a thin plate body obtained by molding a synthetic resin material into a sheet shape. As shown in FIG. 2, the thin plate member 5 is fixed to the upper surface of the channel member 8, that is, the wall surface on the inner side of the housing body 1. The fixing method can be performed by any known means. In this embodiment, as shown in FIG. 3A, an adhesive tape 5a attached to the periphery of the back surface is used.

上記薄板体５の中央部には、雄ネジ部２を貫通させるためのネジ挿通孔４が設けられる。ネジ挿通孔４は雄ネジ部２の呼び径より小径に形成されており、雄ネジ部２を押し込むと、ネジ挿通孔４の周囲が一旦弾性的に変形し、雄ネジ部２を受容する。この状態からレベルフット３を回転させると、薄板体５のネジ挿通孔４の周縁は雄ネジ部２のネジ山の上下動に追随する。 A screw insertion hole 4 for allowing the male screw portion 2 to pass therethrough is provided at the center of the thin plate member 5. The screw insertion hole 4 is formed to have a smaller diameter than the nominal diameter of the male screw portion 2, and when the male screw portion 2 is pushed in, the periphery of the screw insertion hole 4 is once elastically deformed and receives the male screw portion 2. When the level foot 3 is rotated from this state, the peripheral edge of the screw insertion hole 4 of the thin plate member 5 follows the vertical movement of the thread of the male screw portion 2.

図３（ｂ）にレベルフット３引き込み方向の回転に対して薄板体５のネジ挿通孔４の周縁が上方に反り返った状態を、図３（ｃ）にレベルフット３飛び出し方向の操作に対し下方に屈曲した状態を各々示す。これら薄板体５の変形は、弾性変形域内で行われているために、ネジ挿通孔４の周縁部には弾性復元力が発生し、結果、ネジ山面に圧接する。 3B shows a state in which the peripheral edge of the screw insertion hole 4 of the thin plate member 5 is warped upward with respect to the rotation in the level foot 3 pulling direction, and FIG. Each shows the bent state. Since the thin plate member 5 is deformed in the elastic deformation region, an elastic restoring force is generated at the peripheral portion of the screw insertion hole 4, and as a result, the thin plate member 5 is pressed against the thread surface.

図示の状態からさらに雄ネジ部２をねじ込むと、やがてネジ挿通孔４の周縁部は対応するネジ山との当接状態から離脱し、弾性復元力により隣接するネジ山に落ち込み、あるいは跳ね上げられ、再びネジ山面との圧接状態が維持される。 When the male screw portion 2 is further screwed in from the state shown in the drawing, the peripheral portion of the screw insertion hole 4 is eventually released from the contact state with the corresponding screw thread, and falls or jumps up to the adjacent screw thread due to the elastic restoring force. Again, the pressure contact state with the thread surface is maintained.

したがってこの実施の形態において、薄板体５のネジ挿通孔４周縁が、常に雄ネジ部２のネジ山面に圧接しているために、ナット７の雌ネジ部７ａと、レベルフット３の雄ネジ部２との間の隙間は筐体本体部１の内側から完全に閉塞される。このため、筐体本体部１内に溶接スパッタ等が残っていても、上記隙間に落ち込むことがなく、ネジ噛み込みによる作動不良を防止できる。 Therefore, in this embodiment, since the periphery of the screw insertion hole 4 of the thin plate member 5 is always in pressure contact with the thread surface of the male screw portion 2, the female screw portion 7a of the nut 7 and the male screw of the level foot 3 are used. The gap between the parts 2 is completely closed from the inside of the housing body 1. For this reason, even if welding spatter or the like remains in the casing body 1, it does not fall into the gap, and malfunction due to screwing can be prevented.

なお、以上において薄板体５は、合成樹脂製のシートにより形成される場合を示したが、板金等の薄板材により形成することができる。材料自体の延び変形能が劣る場合には、図３（ｄ）に示すように、ネジ挿通孔４の周縁に適数の切り込み６が設けられる。この薄板体５に雄ネジ部２を通過させると、切り込み６間に形成される各片５ｂ、５ｂ・・が片持梁状に弾性変形し、ネジ山に追随する。 In addition, although the thin plate body 5 showed the case where it forms with the sheet | seat made from a synthetic resin in the above, it can form with thin plate materials, such as a sheet metal. When the material itself is inferior in deformability, an appropriate number of cuts 6 are provided on the periphery of the screw insertion hole 4 as shown in FIG. When the male screw portion 2 is passed through the thin plate member 5, the pieces 5b, 5b,... Formed between the cuts 6 are elastically deformed into a cantilever shape and follow the thread.

このように、薄板体５を板金で製する場合には、チャンネル材８への固定は、スポット溶接によることが可能であり、製造が容易で、固定強度も高くなる。 As described above, when the thin plate member 5 is made of sheet metal, the fixing to the channel member 8 can be performed by spot welding, which is easy to manufacture and has a high fixing strength.
