Description

本発明は、電源回路などの電気機器を収容するのに用いられる電気機器用ケースに関する。 TECHNICAL FIELD The present invention relates to an electrical equipment case used to house electrical equipment such as a power supply circuit.

従来の電気機器用ケースの具体例として、特許文献１に記載のものがある。
同文献に記載の電気機器用ケースは、金属板にプレス加工を施すことにより形成されたベース部材および蓋部材を備え、かつこれらが組み付けられた構成である。ここで、前記ベース部材は、電気機器が載せられる底板部、およびその前後両端部から上向きに立ち上がった前後一対の立上り板部を備えた側面視略コ字状である。前記蓋部材は、ベース部材の底板部および電気機器の上方を覆う天板部、およびこの天板部の左右両端部から下向きに立ち下がった左右一対の立下り板部を備えた正面視略コ字状である。
このような構成によれば、電気機器用ケースの全体構成を簡素かつ頑丈なものとしつつ、その製造コストを比較的廉価にすることが可能である。 A specific example of a conventional electric device case is disclosed in Patent Document 1.
The electric device case described in the same document has a base member and a lid member which are formed by pressing a metal plate, and which are assembled together. Here, the base member has a substantially U-shape in a side view including a bottom plate portion on which an electric device is placed and a pair of front and rear rising plate portions rising upward from both front and rear end portions of the bottom plate portion. The lid member has a bottom plate portion of the base member, a top plate portion covering the upper side of the electric device, and a pair of left and right falling plate portions extending downward from both left and right ends of the top plate portion. It is glyph-shaped.
According to such a configuration, it is possible to make the overall configuration of the electric device case simple and sturdy, and to make the manufacturing cost relatively low.

しかしながら、前記従来技術においては、次に述べるように、未だ改善すべき余地があった。 However, the prior art still has room for improvement as described below.

すなわち、電気機器用ケースを構成するベース部材と蓋部材とは、電気機器の上方や周囲を覆うように組み合わされるものの、それら両部材の合わせ部は、ただ単に両部材どうしが当接しているに過ぎない。より具体的には、たとえばベース部材の各立上り板部と、蓋部材の天板部とは、ただ単にこれらが当接しているに過ぎない。このため、それらの相互間には、ケース外面に向けて開口した隙間が発生して、この隙間から電気機器用ケース内にダスト類が進入し、電気機器に触れる可能性がある。これでは、電気機器がたとえば電気回路である場合に、電気回路がショートするなどの不具合を生じる虞があり、適切ではない。 That is, the base member and the lid member that constitute the electric device case are combined so as to cover the upper side and the periphery of the electric device, but the joining portion of the two members is simply abutting against each other. Not too much. More specifically, for example, each rising plate portion of the base member and the top plate portion of the lid member are simply in contact with each other. Therefore, there is a possibility that a gap opens toward the outer surface of the case between them, and dust enters the electric device case through this gap and comes into contact with the electric device. If the electrical equipment is an electrical circuit, for example, this is not appropriate because there is a risk that the electrical circuit will short-circuit.

なお、前記従来技術においては、ベース部材に蓋部材を組み付けてビス止めしようとする際に、蓋部材がベース部材に対して位置ずれし易いものとなっている。したがって、組み付け作業性が劣る不具合もあった。 In addition, in the conventional technology, when the lid member is attached to the base member and screwed, the lid member tends to be displaced from the base member. Therefore, there was also a problem that the assembling workability was inferior.

このような構成によれば、ベース部材の立上り板部と蓋部材の立下り板部との相互間に、ケース外面に向けて開口した隙間が形成されないようにし、ケース内にダスト類が進入することをより適切に防止または抑制することが可能となる。
一方、ベース部材の立上り板部および屈曲片部は、蓋部材の立下り板部がケース外方側に位置ずれすることを効果的に阻止する。したがって、ベース部材に対する蓋部材の組み付け作業性、および組み付け安定性をより向上させることができる。 According to such a configuration, a gap opening toward the outer surface of the case is not formed between the rising plate portion of the base member and the falling plate portion of the lid member, so that dust enters the case. It is possible to prevent or suppress this more appropriately.
On the other hand, the rising plate portion and the bent piece portion of the base member effectively prevent the falling plate portion of the lid member from being displaced to the outside of the case. Therefore, it is possible to further improve workability and stability in assembling the lid member to the base member.

本発明において、好ましくは、前記底板部の左右両端部から下向きに立ち下がった一対の起立片部を、さらに備えており、前記各立下り板部は、前記各屈曲片部よりも下方に延び、前記各立下り板部の内面側に前記各起立片部が重なっている。 In the present invention, preferably, the bottom plate further includes a pair of standing pieces extending downward from both left and right ends of the bottom plate, and each of the falling plates extends downward from each of the bent pieces. , the respective rising pieces are overlapped on the inner surface side of the respective falling plate portions.

このような構成によれば、蓋部材の各立下り板部は、その外面側には、ベース部材の屈曲片部が重なり、かつその内面側には、ベース部材の起立片部が重なった構成となっている。このため、ベース部材に対する蓋部材の各立下り板部の位置決めをより的確に図り、組み付け安定性を一層向上させることができる。 According to such a configuration, each falling plate portion of the lid member overlaps the bent piece portion of the base member on the outer surface side, and overlaps the upright piece portion of the base member on the inner surface side. It has become. Therefore, it is possible to more accurately position the respective falling plate portions of the lid member with respect to the base member, and further improve the assembly stability.

本発明において、好ましくは、前記各立下り板部の前後方向の幅が、上部側よりも下部側の方が小さくなるように、前記各立下り板部の前側縁部および後側縁部の少なくとも下部寄り領域は、側面視において傾斜している。 In the present invention, preferably, the front and rear edges of each of the falling plate portions are arranged so that the width of each of the falling plate portions in the front-rear direction is smaller on the lower side than on the upper side. At least the lower region is inclined in side view.

このような構成によれば、図５を参照して後述する内容からも理解されるように、蓋部材をベース部材に組み付ける場合において、蓋部材の各立下り板部を、ベース部材の屈曲片部の内側に配置させるような作業を円滑に行なうことが可能となる。 According to such a configuration, as will be understood from the contents described later with reference to FIG. 5, when the lid member is assembled to the base member, each falling plate portion of the lid member It is possible to smoothly perform the work of arranging it inside the part.

本発明において、好ましくは、本発明に係る電気機器用ケースを、前記底板部および前記天板部が上下高さ方向に起立し、かつ前記一対の立下り板部が上下高さ方向に離間する起立姿勢で、取付け対象位置上に載置することを可能とする起立姿勢設定用の支持脚部を
、さらに備えている。 In the present invention, it is preferable that the electric device case according to the present invention is such that the bottom plate portion and the top plate portion stand up in the vertical height direction, and the pair of falling plate portions are spaced apart in the vertical height direction. It further comprises a support leg for setting a standing posture, which allows it to be placed on the installation target position in a standing posture.

このような構成によれば、電気機器用ケースを本発明が意図する姿勢とは異なった所定の起立姿勢に設定することが可能となり、便利である。 According to such a configuration, it is possible to set the electric device case in a predetermined standing posture different from the posture intended by the present invention, which is convenient.

本発明において、好ましくは、前記各立上り板部および前記各下向き片部がネジ部材を用いて締結されるネジ締結部を、さらに備えている。 In the present invention, preferably, each of the rising plate portions and each of the downward pieces is further provided with a screw fastening portion that is fastened using a screw member.

このような構成によれば、前記ネジ締結部は、ベース部材の各立上り板部と、蓋部材の下向き片部とが互いに位置ずれしないようにこれらの部分を効果的に締結する。したがって、ネジ締結部の総数を少なくしつつ、ベース部材に対する蓋部材の固定を適切に図ることができる。 According to such a configuration, the screw fastening portion effectively fastens each rising plate portion of the base member and the downward piece portion of the lid member so that these portions are not displaced from each other. Therefore, it is possible to appropriately fix the lid member to the base member while reducing the total number of screw fastening portions.

It is substantially the same as that and has a substantially rectangular shape that is oblong in a front view.

蓋部材３は、ベース部材２に組み付けられているが、この組み付け状態においては、蓋部材３の天板部３０の前後両端部付近が、ベース部材２の一対の立上り板部２１の上側に位置し、かつ一対の下向き片部３２が、一対の立上り板部２１の上部の外面側に重なっている。ネジ締結部４は、下向き片部３２および立上り板部２１を締結すべく、それらに設けられている孔部３２ａ，２１ａにビス４０（ネジ部材）が挿通して締め付けられた部位であり、本実施形態においては、合計２箇所のみ設けられ、ベース部材２に対する蓋部材３の取付け・取り外し作業の容易化が図られている。 The lid member 3 is assembled to the base member 2 . In this assembled state, the vicinity of the front and rear end portions of the top plate portion 30 of the lid member 3 is positioned above the pair of rising plate portions 21 of the base member 2 . Moreover, the pair of downward piece portions 32 overlaps the upper outer surface side of the pair of rising plate portions 21 . The screw fastening portion 4 is a portion in which a screw 40 (screw member) is inserted and tightened through holes 32a and 21a provided in the downward piece portion 32 and the rising plate portion 21 in order to fasten them. In the embodiment, only a total of two locations are provided to facilitate attachment/detachment work of the lid member 3 to/from the base member 2 .

蓋部材３の各立下り板部３１は、前後に間隔を隔てた一対の屈曲片部２２の相互間に形成されている開口領域Ｓａを塞ぐように、それら一対の屈曲片部２２の内側に位置している。ここで、開口領域Ｓａは、電気機器１の配置箇所の左右両側方の領域に相当する。したがって、電気機器１の配置箇所の左右両側方は、立下り板部３１によって覆われており、また前記配置箇所の前方および後方は、立上り板部２１によって覆われている。 Each of the falling plate portions 31 of the lid member 3 extends inside the pair of bending piece portions 22 so as to close the opening region Sa formed between the pair of bending piece portions 22 spaced in the front-rear direction. positioned. Here, the opening area Sa corresponds to areas on both the left and right sides of the location where the electric device 1 is arranged. Therefore, the left and right sides of the location where the electrical device 1 is placed are covered with the falling plate portions 31 , and the front and rear of the location are covered with the rising plate portions 21 .

図４（ａ）によく表れているように、各立下り板部３１の下端先端寄り部分は、各屈曲片部２２よりも下方に延び、起立片部２３ａの外面側に重なっている。屈曲片部２２の下端部と起立片部２３ａの上端部との間には、立下り板部３１の厚みと同程度の幅の隙間ｃ１が形成されており、立下り板部３１は、その隙間ｃ１に挿通されていることにより、前記構成が得られている。 As shown in FIG. 4(a), the lower tip portion of each falling plate portion 31 extends downward from each bending piece portion 22 and overlaps the outer surface side of the standing piece portion 23a. Between the lower end portion of the bending piece portion 22 and the upper end portion of the standing piece portion 23a, a gap c1 having a width approximately equal to the thickness of the falling plate portion 31 is formed. The above configuration is obtained by being inserted in the gap c1.

図４（ｂ）に示すように、蓋部材３がベース部材２に未だ組み付けられていない自然状態において、一対の立下り板部３１は、好ましくは、同図仮想線で示すように、下部側が上部側よりも左右幅方向の相互間隔が広くなる傾斜状とされ、弾発力をもって同図の矢印Ｎａ方向に振れるように変形可能である。このような構成によれば、蓋部材３を下降させてベース部材２に組み付ける際に、一対の立下り板部３１の下端部を、前記弾発力を利用
して屈曲片部２２の内面部に当接させ、かつこの屈曲片部２２の内面部に沿わせて下降させることができる。このことにより、図４（ｃ）に示すように、各立下り板部３１の下端部を前記した隙間ｃ１に挿通させる作業が容易化される。 As shown in FIG. 4(b), in the natural state where the lid member 3 is not yet assembled to the base member 2, the pair of falling plate portions 31 preferably have lower sides as indicated by phantom lines in the figure. It is inclined so that the mutual interval in the lateral width direction is wider than that on the upper side, and can be deformed so as to swing in the direction of the arrow Na in the figure with elastic force. According to such a configuration, when the cover member 3 is lowered and assembled to the base member 2, the lower end portions of the pair of falling plate portions 31 are moved to the inner surface portion of the bending piece portion 22 by utilizing the elastic force. , and can be lowered along the inner surface of the bent piece 22 . As a result, as shown in FIG. 4(c), the operation of inserting the lower end portion of each of the falling plate portions 31 into the gap c1 is facilitated.

図５に示すように、蓋部材３の立下り板部３１のうち、下向き片部３２に対応した領域Ｈａよりも下側の領域Ｈｂにおいては、立下り板部３１の前側縁部３１ａおよび後側縁部３１ｂは、上部から下部に進むほど立下り板部３１の前後方向中央側に位置するように傾斜している。このことにより、立下り板部３１の前後方向の幅Ｌは、上部側から下部側に進むほど減少している。なお、前側縁部３１ａおよび後側縁部３１ｂの傾斜角は小さめであり、立下り板部３１の最下部の前後方向の幅Ｌａが、前後一対の屈曲片部２２の相互間寸法Ｌｂよりも小さくならず、前側縁部３１ａおよび後側縁部３１ｂが各屈曲片部２２の内側に適切に重なった配置となるように配慮されている。
このような構成によれば、蓋部材３をベース部材２に組み付ける場合において、立下り板部３１を前後一対の立上り板部２１の相互間にその上方から下降させていくときに、その作業を容易かつ円滑に行なうことが可能となる。
なお、下向き片部３２については、図５の一部拡大図の仮想線で示すような傾斜状となるように形成すれば、この下向き片部３２を各立上り板部２１の外面側に配置させることが容易となり、そのような構成とすることも可能である。 As shown in FIG. 5, in the falling plate portion 31 of the lid member 3, in the region Hb below the region Ha corresponding to the downward piece portion 32, the front side edge portion 31a and the rear side edge portion 31a of the falling plate portion 31 The side edge portion 31b is inclined so as to be positioned toward the front-rear direction center side of the falling plate portion 31 as it progresses from the upper portion to the lower portion. As a result, the width L of the trailing plate portion 31 in the front-rear direction decreases from the upper portion toward the lower portion. The inclination angle of the front side edge portion 31a and the rear side edge portion 31b is small, and the width La of the lowermost portion of the falling plate portion 31 in the front-rear direction is larger than the mutual dimension Lb between the pair of front and rear bending pieces 22. Consideration is given so that the front side edge portion 31a and the rear side edge portion 31b are appropriately overlapped on the inner side of each bending piece portion 22 without becoming smaller.
According to such a configuration, when the lid member 3 is assembled to the base member 2, when the falling plate portion 31 is lowered between the pair of front and rear rising plate portions 21 from above, the operation is reduced. This can be done easily and smoothly.
If the downward piece 32 is formed to be inclined as indicated by the imaginary line in the partially enlarged view of FIG. It becomes easy to do so, and such a configuration is also possible.

次に、前記した電気機器用ケースＣの作用について説明する。 Next, the operation of the electric device case C will be described.

まず、ベース部材２と蓋部材３との合わせ部に、電気機器用ケースＣ内にダスト類を進入させ易い上向きや横向き開口状の隙間が形成されないようにすることが可能である。具体的には、ベース部材２の前後一対の立上り板部２１の上端部は、蓋部材３の天板部３０と下向き片部３２とが繋がった側面断面視略Ｌ字状の角部の内側に位置している。このため、立上り板部２１の上端部と天板部３０との合わせ部に、上向きや横向きに開口した隙間は形成されていない。また、ベース部材２の各立上り板部２１の左右両端部には屈曲片部２２が連設されており、この部分は平面断面視略Ｌ字状の角部となっているが、その内側に蓋部材３の立下り板部３１の前側縁部３１ａおよび後側縁部３１ｂが位置している。このため、立上り板部２１の左右両端部と蓋部材３の立下り板部３１との合わせ部にも、上向きや横向きに開口した隙間は形成されていない。 First, it is possible to prevent formation of upward or sideways opening-like gaps that facilitate the entry of dust into the electric device case C at the mating portion of the base member 2 and the lid member 3 . Specifically, the upper end portion of the pair of front and rear rising plate portions 21 of the base member 2 is located inside the corner portion of the approximately L-shaped cross section where the top plate portion 30 and the downward piece portion 32 of the lid member 3 are connected. located in For this reason, a gap opening upward or sideways is not formed in the joining portion between the upper end portion of the rising plate portion 21 and the top plate portion 30 . Further, bent pieces 22 are continuously provided at both left and right end portions of each of the rising plate portions 21 of the base member 2, and these portions form corners of a substantially L-shaped plane cross section. A front edge portion 31a and a rear edge portion 31b of the falling plate portion 31 of the lid member 3 are located. For this reason, no upward or sideways opening gap is formed in the mating portion between the right and left end portions of the rising plate portion 21 and the falling plate portion 31 of the lid member 3 .

さらに、蓋部材３の立下り板部３１の下端部は、ベース部材２の起立片部２３ａに重なっている。このため、これらの両者間には、下向き開口の微小な隙間が形成される可能性はあるものの、このような部位から電気機器用ケースＣ内にダスト類が進入する虞は殆どない。立下り板部３１の外面側には、屈曲片部２２が重なっており、立下り板部３１の下端部が起立片部２３ａから離間する方向に変形または変位することは阻止されている。したがって、立下り板部３１の下端部と起立片部２３ａとの相互間に形成される下向き開口の隙間は、殆どゼロにすることができ、この部分から電気機器用ケースＣ内にダスト類が進入することは、より確実に防止される。
このように、本実施形態の電気機器用ケースＣによれば、ベース部材２と蓋部材３との合わせ部に、電気機器用ケースＣ内にダスト類を進入させ易い隙間が形成されないようにすることができる。したがって、電気機器１を適切に保護し、たとえば電気機器１がダスト類と接触することによってショートするといった不具合を適切に防止することができる。 Furthermore, the lower end portion of the falling plate portion 31 of the lid member 3 overlaps the upright piece portion 23a of the base member 2 . For this reason, although there is a possibility that a minute gap with a downward opening may be formed between these two, there is almost no possibility that dust or the like will enter the electric device case C from such a portion. The bending piece portion 22 overlaps the outer surface side of the trailing plate portion 31 to prevent the lower end portion of the trailing plate portion 31 from being deformed or displaced in the direction away from the standing piece portion 23a. Therefore, the gap of the downward opening formed between the lower end portion of the falling plate portion 31 and the rising piece portion 23a can be made almost zero, and dust and the like can enter the electrical equipment case C from this portion. Entry is more reliably prevented.
As described above, according to the electrical device case C of the present embodiment, a gap that facilitates entry of dust into the electrical device case C is prevented from being formed at the joint between the base member 2 and the lid member 3. be able to. Therefore, it is possible to appropriately protect the electrical device 1 and appropriately prevent problems such as short-circuiting due to contact of the electrical device 1 with dust, for example.

一方、ベース部材２に蓋部材３を組み付ける場合には、図４を参照して説明したように、蓋部材３の左右一対の立下り板部３１を、一対の屈曲片部２２の相互間に配置させつつ、蓋部材３をベース部材２の上方から下降させ、かつ各立下り板部３１の下端部を隙間ｃ１に挿通させる。また、蓋部材３の天板部３０については、ベース部材２の立上り板部２
１の上側に載せる。このような作業の後に、一対のネジ締結部４を利用し、下向き片部３２を立上り板部２１にビス止め締結すればよい。このような一連の作業は容易であり、組み付け作業性がよい。 On the other hand, when the lid member 3 is assembled to the base member 2, the pair of left and right falling plate portions 31 of the lid member 3 are placed between the pair of bent pieces 22 as described with reference to FIG. While being arranged, the lid member 3 is lowered from above the base member 2, and the lower ends of the respective falling plate portions 31 are inserted into the gaps c1. Further, the top plate portion 30 of the lid member 3 is the rising plate portion 2 of the base member 2 .
Place on top of 1. After such work, the pair of screw fastening portions 4 may be used to fasten the downward piece 32 to the rising plate portion 21 with screws. Such a series of operations is easy, and assembly workability is good.

ベース部材２および蓋部材３のビス止めは、一対のネジ締結部４においてなされているに過ぎないものの、ベース部材２と蓋部材３とは、次に述べるように、ネジ締結部４以外の箇所において位置ずれが防止された状態に組み付けられている。
すなわち、蓋部材３の前後一対の下向き片部３２は、ベース部材２の一対の立上り板部２１を前後方向において挟んだ配置にある。このため、下向き片部３２が連設された天板部３０と立上り板部２１との前後方向の位置ずれは適切に防止される。また、蓋部材３の左右一対の立下り板部３１は、その外面側にベース部材２の屈曲片部２２が重なり、かつ内面側にベース部材２の起立片部２３ａが重なった配置にある。このため、各立下り板部３１とベース部材２との左右幅方向の位置ずれも適切に防止される。このようなことから、ベース部材２と蓋部材３との組み付け状態を安定したものとすることができる。 Although the base member 2 and the lid member 3 are screwed together only at a pair of screw fastening portions 4, the base member 2 and the lid member 3 are connected at locations other than the screw fastening portions 4 as described below. is assembled in a state in which positional deviation is prevented.
That is, the pair of front and rear downward piece portions 32 of the lid member 3 are arranged to sandwich the pair of rising plate portions 21 of the base member 2 in the front and rear direction. Therefore, the positional deviation in the front-rear direction between the top plate portion 30 and the rising plate portion 21, to which the downward piece portion 32 is continuously provided, is appropriately prevented. The pair of left and right falling plate portions 31 of the lid member 3 are arranged such that the bending piece portion 22 of the base member 2 overlaps on the outer surface side thereof, and the rising piece portion 23a of the base member 2 overlaps on the inner surface side thereof. Therefore, positional deviation in the lateral width direction between each of the trailing plate portions 31 and the base member 2 is also appropriately prevented. As a result, the state of assembly between the base member 2 and the lid member 3 can be stabilized.

図６ないし図８は、本発明の他の実施形態を示している。これらの図において、前記実施形態と同一または類似の要素には、前記実施形態と同一の符号を付すこととし、重複説明は省略する。 Figures 6-8 show another embodiment of the invention. In these figures, elements that are the same as or similar to those in the above embodiment are denoted by the same reference numerals as those in the above embodiment, and repeated explanations are omitted.

図６に示す電気機器用ケースＣａは、ベース部材２に設けられる一対の支持脚部２３，２３Ａを備えているが、これらのうち、一方の支持脚部２３Ａは、起立姿勢設定用の支持脚部であり、上下高さ方向に延びた起立片部２３ａは有するものの、この起立片部２３ａに屈曲状の水平板部２３ｂが連設された構成とはされていない。これに対し、他方の支持脚部２３は、前記実施形態の電気機器用ケースＣと同様に、起立片部２３ａおよび水平板部２３ｂを有している。ただし、起立片部２３ａの上下幅は、やや小さくされている。 The electric device case Ca shown in FIG. 6 includes a pair of support legs 23 and 23A provided on the base member 2. One of these support legs 23A is a support leg for setting a standing posture. Although it has an upright piece 23a extending in the vertical direction, it does not have a bent horizontal plate portion 23b connected to the upright piece 23a. On the other hand, the other support leg portion 23 has an upright piece portion 23a and a horizontal plate portion 23b, as in the electric device case C of the above-described embodiment. However, the vertical width of the standing piece 23a is slightly reduced.

図７および図８に示すように、電気機器用ケースＣａは、起立姿勢設定用の支持脚部２３Ａが、最下部に位置した起立姿勢とする。この起立姿勢においては、底板部２０および天板部３０が上下高さ方向に起立し、かつ一対の立下り板部３１が上下高さ方向に離間している。支持脚部２３Ａは、フラットであるため、電気機器用ケースＣａを傾かせることなく、所望の設置対象場所に安定した状態に設置することが可能である。このような設置状態においては、図８に示すように、蓋部材３を水平方向にスライドさせることにより、この蓋部材３をベース部材２に対して着脱することが可能である。電気機器１のメンテナンス作業を行なう際に、蓋部材３をベース部材２の上方に取り外すことが困難な状況下に電気機器用ケースＣａを設置する場合、図７および図８に示した起立姿勢に設置して対応すればよく、便利である。 As shown in FIGS. 7 and 8, the electric device case Ca is in a standing posture in which the support legs 23A for setting the standing posture are positioned at the lowest position. In this standing posture, the bottom plate portion 20 and the top plate portion 30 stand up in the vertical height direction, and the pair of falling plate portions 31 are spaced apart in the vertical height direction. Since the support leg portion 23A is flat, it is possible to stably install the electric device case Ca at a desired installation location without tilting the electric device case Ca. In such an installed state, as shown in FIG. 8, the lid member 3 can be attached to and detached from the base member 2 by sliding the lid member 3 in the horizontal direction. When the electrical equipment case Ca is installed in a situation in which it is difficult to remove the lid member 3 above the base member 2 when performing maintenance work on the electrical equipment 1, the upright position shown in FIGS. It is convenient to install and respond.
