Description
本発明は、基礎床面上に支持脚で支持される床パネルを支持脚に固定するパネル押えに関するものである。 The present invention relates to a panel presser for fixing the floor panels supported by the support legs on a foundation floor to support legs.
近年、オフィスビル等では、配線空間を確保するために、床パネルを基礎床面上に浮かして敷設する二重床が多く採用されている。床パネルを二重床方式で敷くには、基礎床面上に支持脚を立て、この支持脚で床パネルを支持して床パネルの上方からパネル押えを支持脚にネジ込んで固定している。この場合、パネル押えの上面には工具を係合できる工具係合形状が形成されており、メンテナンスやレイアウト変更のときには、この係合形状に工具を係合してパネル押えを操作して床パネルを外したり、取り付けたりしている。 In recent years, in an office building or the like, in order to secure a wiring space, a double floor in which a floor panel is floated and laid on a basic floor surface is often employed. To lay the floor panel in a double floor system, support legs are set up on the foundation floor, and the floor panel is supported by these support legs, and the panel presser is screwed into the support legs from above the floor panel and fixed. . In this case, a tool engagement shape that can engage the tool is formed on the upper surface of the panel presser. When maintenance or layout change is performed, the tool is engaged with this engagement shape and the panel presser is operated to operate the floor panel. Is removed or attached.
ところが、最近では、セキュリティーが叫ばれており、入口に鍵がかかる居室等の専用部分では、マイナス（プラス）ドライバーや六角レンチといった汎用工具での操作で問題はないが、誰もが侵入できる廊下等の共通部分では、これら汎用工具では操作できないような工夫がなされている。具体的には、パネル押えの工具係合形状を特殊形状（構造）としてこの特殊形状に係合できる専用工具を用いて操作している。すなわち、パネル押えをセキュリティー仕様と通常仕様とに分け、場所によって使い分ける方法をとっていた。 However, recently, security has been screamed, and there are no problems with operations with general tools such as a flat-blade screwdriver or hexagon wrench in a dedicated part such as a living room where the entrance is locked, but a corridor where anyone can enter In common parts such as these, a device that cannot be operated by these general-purpose tools is devised. Specifically, the tool engagement shape of the panel presser is operated as a special shape (structure) using a dedicated tool that can be engaged with the special shape. In other words, the panel presser was divided into security specifications and normal specifications, and a method was used depending on the location.
パネル押えの工具係合形状に特殊形状を施したものとして下記特許文献１及び２に示されるものがある。このうち、特許文献１のものは、パネル押えをピンを有する上部構造体とピンに係合して支持脚に螺合する下部構成体とで構成し、専用工具でピンを押し下げて下部構成体に係合させないと下部構成体を回せないようにしたものである。これに対して、特許文献２のものは、パネル押えの上面に複数の穴を形成し、裏面にこの穴に係合する突起を設けた工具によって操作するようにしている。 Patent Documents 1 and 2 listed below are examples in which a special shape is applied to the tool engagement shape of the panel presser. Among these, in Patent Document 1, the panel presser is composed of an upper structure having a pin and a lower structure that engages with the pin and is screwed to a support leg, and the pin is pushed down by a dedicated tool to lower the structure. The lower structure cannot be turned unless it is engaged with. On the other hand, in Patent Document 2, a plurality of holes are formed on the upper surface of the panel presser, and the rear surface is operated by a tool provided with a protrusion that engages with the holes.
いずれも、専用工具がなければ操作できないことは共通しており、この専用工具では、共通部分等に敷設してある通常仕様のパネル押えは操作できない。したがって、これら両仕様のパネル押えを操作する必要があるときには、両方の工具を所持していなければならず、面倒で負担のかかる作業を強いられていた。また、セキュリティー仕様と通常仕様のパネル押えが混ざって使用されていた場合も同様である。
本発明が解決しようとする課題は、通常仕様とセキュリティー仕様のパネル押えが専用部分と共通部分で分けて使用されていても、これを一本の専用工具で操作できるようにしたものである。 The problem to be solved by the present invention is that even if the panel presser of the normal specification and the security specification is used separately for the dedicated portion and the common portion, it can be operated with a single dedicated tool.
以上の課題の下、本発明は、請求項１に記載した、床パネルを支持脚に固定するパネル押えであり、専用工具に形成される専用係合部のみに係合する専用係合形状と、汎用工具及び専用工具に形成される汎用係合部には非係合とする汎用非係合形状とが形成されていることを特徴とするパネル押えを提供するとともに、これにおいて、請求項２の、パネル押えが、床パネルを上から押える頭部と、頭部の下方に突出し、支持脚を構成するネジ支柱に螺合するネジ穴が形成された胴部を有するものであり、この頭部及び／又は胴部に専用係合形状と汎用非係合形状が形成される手段を提供する。 Under the above-mentioned problems, the present invention is a panel presser for fixing a floor panel to a support leg according to claim 1, and has a dedicated engagement shape that engages only with a dedicated engagement portion formed on a dedicated tool. A general-purpose tool and a general-purpose non-engagement shape formed so as to be non-engaged are formed in a general-purpose tool and a general-purpose engaging portion formed in the special-purpose tool. The panel presser has a head that presses the floor panel from above, and a body that protrudes below the head and has a screw hole that is screwed into a screw support that constitutes the support leg. A means for forming a dedicated engagement shape and a general-purpose non-engagement shape in the body and / or the body is provided.
また、以上のパネル押えとして、請求項３の、専用係合形状が、頭部の上面に形成された多角形穴であり、汎用非係合形状が多角形穴の底部からネジ穴に貫通する逃がし孔である手段、請求項４の、多角形穴と逃がし孔が同一形状に形成されて兼用される手段を提供する。 Further, as the above panel presser, the exclusive engagement shape of claim 3 is a polygonal hole formed on the upper surface of the head, and the general-purpose non-engagement shape penetrates from the bottom of the polygonal hole to the screw hole. Means which is an escape hole, the means according to claim 4, wherein the polygonal hole and the escape hole are formed in the same shape and used together.
請求項１〜４のパネル押えによると、汎用工具では操作できず、専用工具のみでしか操作できないことから、セキュリティーが確保できる。 According to the panel pressing of claims 1 to 4, can not be operated in the ordinary tool, since it can not only operate the special tool, security Ru secured.
以下、本発明の実施の形態を図面を参照して説明する。図１は本発明の一例を示すパネル押えと専用工具の使用状態を示す説明図、図２はパネル押えを取り付けた状態の平面図，図３は図２のＡーＡ断面図であるが、この床パネルの敷設構造は、床パネル１のコーナーの位置で基礎床面２上に置かれる支持脚３と、支持脚３で支持された床パネル１を支持脚２に固定するパネル押え４とからなる。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view showing a use state of a panel presser and a dedicated tool showing an example of the present invention, FIG. 2 is a plan view of a state in which the panel presser is attached, and FIG. 3 is a cross-sectional view taken along line AA in FIG. The floor panel laying structure includes a support leg 3 placed on the foundation floor 2 at the corner of the floor panel 1, and a panel presser 4 for fixing the floor panel 1 supported by the support leg 3 to the support leg 2. Consists of.
このうち、支持脚３は、基礎床面２上に適宜固着されて置かれる接地板５から倒れに対して十分な剛性を有するネジ支柱６が上起しているものであり、ネジ支柱６に螺合したナット７に受け盤８を止め付け、受け盤８で床パネル１を載せる載せ盤９を支持したものである。この場合において、載せ盤９は、その外周端が下方に屈曲して受け盤８の外周を包み込んで位置ずれを規制している。 Among them, the support leg 3 is a structure in which a screw support 6 having sufficient rigidity against falling is raised from a ground plate 5 that is fixed and appropriately fixed on the foundation floor 2. The receiving board 8 is fixed to the screwed nut 7 and the receiving board 8 supports the mounting board 9 on which the floor panel 1 is placed. In this case, the mounting board 9 is bent downward at its outer peripheral edge so as to wrap around the outer periphery of the receiving board 8 to regulate the positional deviation.
床パネル１は、底面部１５と側面部１１と側面部１１の上端外側に折り曲げ形成した水平フランジとを有する縁付容器状をした下面板に、平板状の上面板を被せて外周を巻き込んで接合した構造の鋼板製のもので、全周に上面板と下面板との重合フランジを有している。コーナー先端の重合フランジには四半径円状の切欠部を有する低段部１０が四半径円状に段押し形成されており、対角線方向には低段部１０の起立壁から所定間隔隔てて側面部１１が降りている。したがって、起立壁と側面部１１との間は逆Ｕ字形の突出部を形成することになるが、これを首部１２とする。側面部１１は、辺に沿って延びて床パネル１の底面を周回しているが、コーナーは対角線方向に対する直交面を形成するよう４５°に面取りされている。 The floor panel 1 is formed by covering a lower surface plate having an edged container shape having a bottom surface portion 15, a side surface portion 11, and a horizontal flange formed by bending outside the upper end of the side surface portion 11, and covering the outer periphery with a flat upper surface plate. It is made of steel plates with a joined structure, and has a superposed flange of upper and lower plates on the entire circumference. A low step portion 10 having a four-radius circular cutout is stepped and formed on the overlapping flange at the corner tip in a four-radius circle shape, and in a diagonal direction, the side surface is spaced from the standing wall of the low step portion 10 by a predetermined distance. Part 11 is down. Therefore, an inverted U-shaped projecting portion is formed between the standing wall and the side surface portion 11. The side surface portion 11 extends along the side and circulates around the bottom surface of the floor panel 1, but the corner is chamfered at 45 ° so as to form an orthogonal surface with respect to the diagonal direction.
低段部１０に続く辺方向には、辺部に沿って下方へ突出する厚肉縁部１３が側面部１１近くまで延びて形成されている。厚肉縁部１３は、上面板の外周による下面板の水平フランジの巻き込みによって得られるので、特別な加工の必要がなく、下面側へ巻き込んだ上面板の板厚分だけ重合フランジから下方へ突出した厚肉状となっている。この他、低段部１０の起立壁の上端からは平坦な上面部１４に形成され、側面部１１の下端からは底面部１５に形成されている。 In the side direction following the low step portion 10, a thick edge portion 13 that protrudes downward along the side portion is formed extending to the vicinity of the side surface portion 11. Since the thick edge portion 13 is obtained by the winding of the horizontal flange of the lower surface plate around the outer periphery of the upper surface plate, there is no need for special processing, and it protrudes downward from the overlapping flange by the thickness of the upper surface plate wound to the lower surface side. It has become thick. In addition, a flat upper surface portion 14 is formed from the upper end of the standing wall of the low step portion 10, and a bottom surface portion 15 is formed from the lower end of the side surface portion 11.
パネル押え４は、円板状の頭部１６と、頭部１６よりも径の小さな胴部１７とからなるものである。この頭部１６は、四枚の床パネル１のコーナーが集合状態で円状となる低段部１０の中に入り込む径を有しており、胴部１７は、上記した載せ盤９の中央部に形成された案内筒９ａの中に入り込む径を有しており、その上部と下部において外周が案内筒９ａの内周に摺接させられるものであり、その中心には、ネジ支柱６に螺合できるネジ穴１７ａが形成されている。なお、パネル押え４のこの他の構造については後述する。 The panel retainer 4 includes a disc-shaped head 16 and a body portion 17 having a diameter smaller than that of the head 16. The head 16 has a diameter that allows the corners of the four floor panels 1 to enter the lower step portion 10 that is circular in the assembled state, and the trunk portion 17 is a central portion of the above-described platform 9. The guide cylinder 9a has a diameter that enters the guide cylinder 9a. The outer periphery of the guide cylinder 9a is in sliding contact with the inner periphery of the guide cylinder 9a. A screw hole 17a that can be mated is formed. The other structure of the panel retainer 4 will be described later.
以上の床パネル１は、支持脚３で支持される載せ盤９の上に載せられるが、この場合の載せ盤９は、最内周に低段部１０を受ける受面部１８が中央にパネル押え４の胴部１７が入り込む貫通孔を有して案内筒９ａがドーナツ円状に形成されている。そして、受面部１８に続く対角線方向には受面部１８より高い床パネル１の首部１２に入り込む高堰部１９と、これよりもかなり低い載せ部２０とが連続して形成され、辺方向には高堰部１９よりは低い低堰部２１と、低堰部２１よりは更に低い仕切り部２２とが連続して形成されている。 The above-mentioned floor panel 1 is placed on the platform 9 supported by the support legs 3. In this case, the platform 9 has a receiving surface portion 18 that receives the low step portion 10 at the innermost periphery in the center. The guide cylinder 9a is formed in a donut shape with a through-hole into which the four body parts 17 enter. In the diagonal direction following the receiving surface portion 18, a high weir portion 19 that enters the neck portion 12 of the floor panel 1 higher than the receiving surface portion 18 and a mounting portion 20 that is considerably lower than this are continuously formed. A low dam part 21 lower than the high dam part 19 and a partition part 22 lower than the low dam part 21 are continuously formed.
この場合、受面部１８の載せ部２０上面からの高さを、床パネル１の底面部１５から低段部１０の下面までの高さよりも若干低く設定している他、高堰部１９の高さも、同様に首部１２の下面までの高さよりも若干低く設定している。また、高堰部１９の低段部１０側の面は起立壁に沿う形状にし、側面部１２側の面は側面部１２に沿う形状にしている。そして、低堰部２１の幅は、隣接する床パネル１の両方の厚肉縁部１３を収容して位置規制を行うために、厚肉縁部１３の幅の倍を有しており、仕切り部２２の幅は、隣接する床パネル１の側面部１１間に入り込んで位置規制を行うために、床パネル１の辺部と側面部１１までの長さの倍を有している。 In this case, the height of the receiving surface portion 18 from the upper surface of the mounting portion 20 is set slightly lower than the height from the bottom surface portion 15 of the floor panel 1 to the lower surface of the low step portion 10, and the height of the high weir portion 19 is set. Similarly, the height to the lower surface of the neck portion 12 is set slightly lower. Further, the surface of the high weir portion 19 on the low step portion 10 side is shaped along the upright wall, and the surface on the side surface portion 12 side is shaped along the side surface portion 12. And the width of the low dam part 21 has twice the width of the thick edge part 13 in order to accommodate both the thick edge parts 13 of the adjacent floor panel 1, and to perform position control, The width of the portion 22 is double the length from the side portion of the floor panel 1 to the side portion 11 in order to enter the space between the side portions 11 of the adjacent floor panels 1 and perform position regulation.
次に、床パネル１の支持脚３への載せ方であるが、ナット７を上下して載せ盤９を所定の高さに調整したなら、低段部１０が載せ盤９の受面部１８に載り、コーナー両辺の側面部１１が隣接する二つの仕切り部２２の間に嵌まり込む状態にしてその底面部１５を載せ部２０上に置く。すると、対角線方向には首部１２が高堰部１９を内外から挟み込み、辺方向には厚肉縁部１３が低堰部２１に嵌まり込む状態になる。このとき、高堰部１９の厚みを首部１２の幅に合わせておくと、首部１２が高堰部１９を挟圧することになり、位置ずれは一層抑制される。このような操作を四枚の床パネル１について行う。 Next, as to how to place the floor panel 1 on the support leg 3, if the nut 7 is moved up and down to adjust the platform 9 to a predetermined height, the low step portion 10 becomes the receiving surface portion 18 of the platform 9. The bottom surface portion 15 is placed on the mounting portion 20 in such a manner that the side surface portions 11 on both sides of the corner are fitted between the two adjacent partition portions 22. Then, the neck portion 12 sandwiches the high dam portion 19 from inside and outside in the diagonal direction, and the thick edge portion 13 fits into the low dam portion 21 in the side direction. At this time, if the thickness of the high dam portion 19 is matched with the width of the neck portion 12, the neck portion 12 sandwiches the high dam portion 19, and the displacement is further suppressed. Such an operation is performed on the four floor panels 1.
このとき、基礎床面２の不陸によって支持脚３が傾斜していたり、床パネル１の製造誤差によって低段部１０の高さが揃わない場合があるが、受面部１８の高さを低段部１０の高さに対し、及び高堰部１９の高さを首部１２の高さに対しそれぞれ若干低く設定することで、それらを吸収した状態でのパネル押え４の締め付けを可能にしている。また、低段部１０を弾性変形させた状態で挟圧すれば、パネル押え４の緩み止め効果も発揮する。 At this time, the support legs 3 may be inclined due to unevenness of the foundation floor surface 2 or the height of the low step portion 10 may not be uniform due to manufacturing errors of the floor panel 1, but the height of the receiving surface portion 18 is reduced. By setting the height of the step portion 10 and the height of the high dam portion 19 slightly lower than the height of the neck portion 12, the panel presser 4 can be tightened in a state in which they are absorbed. . Moreover, if the low step part 10 is clamped in an elastically deformed state, the effect of preventing the panel retainer 4 from loosening is also exhibited.
この状態で、パネル押え４を適宜な工具を用いてネジ支柱６に螺合して行くと、その胴部１７の外周が載せ盤９の案内筒９ａの内周に摺接しながら下降して互いに位置ずれ及び変形を規制し合い、頭部１６は、低段部１０の中に入り込んで受面部１８とで低段部１０を直接上下から挟圧する。このとき、頭部１６の外形を低段部１０の内径に合わせておくと、低段部１０の起立壁を高堰部１９とで挟圧することになり、首部１２による高堰部１９の挟圧とで二重の位置ずれ規制構造となる。また、胴部１７の外周を低段部１０の内周に摺接するようにしておくことで、低段部１０を高堰部１９とで挟圧することになり、更なる位置ずれ規制構造となる。 In this state, when the panel retainer 4 is screwed into the screw strut 6 using an appropriate tool, the outer periphery of the trunk portion 17 descends while sliding on the inner periphery of the guide tube 9a of the platform 9 and moves to each other. The positional deviation and deformation are regulated, and the head 16 enters the low step portion 10 and directly clamps the low step portion 10 from above and below with the receiving surface portion 18. At this time, if the outer shape of the head portion 16 is matched with the inner diameter of the low step portion 10, the standing wall of the low step portion 10 is pinched by the high dam portion 19, and the high dam portion 19 is sandwiched by the neck portion 12. It becomes a double displacement control structure with pressure. Further, by allowing the outer periphery of the body portion 17 to be in sliding contact with the inner periphery of the low step portion 10, the low step portion 10 is pinched by the high dam portion 19, and a further positional deviation restricting structure is obtained. .
以上により、床パネル１が対角線方向にずれようとすると、床パネル１の首部１２による高堰部１９の挟み付けを始めとする上述した位置ずれ規制構造が協働的に働き、その位置ずれを確実に規制する。また、辺方向にずれようとしても、上述した位置ずれ規制構造が対角線方向に広がりを有して放射状に形成されているため、その位置ずれを規制するが、床パネル１の厚肉縁部１３の低堰部２０への嵌まり込み及び側面部１２の仕切り部２２間への嵌まり込みにより、その位置ずれを一層確実に規制する。このようにして、床パネル１は、対角線方向にも辺方向にも、位置ずれが二重、三重に規制される。 As described above, when the floor panel 1 tries to shift in the diagonal direction, the above-described displacement control structure including the sandwiching of the high weir portion 19 by the neck portion 12 of the floor panel 1 works cooperatively, Be sure to regulate. In addition, even when trying to shift in the side direction, the above-described positional shift restricting structure is radially formed with a spread in the diagonal direction, so that the positional shift is controlled, but the thick edge portion 13 of the floor panel 1 is controlled. The position shift is more reliably regulated by fitting into the low dam part 20 and fitting between the partition parts 22 of the side face part 12. In this way, the floor panel 1 is regulated to be double or triple in positional deviation both in the diagonal direction and in the side direction.
ところで、以上のようにして支持脚２に固定した床パネル１は、メンテナンスやレイアウト変更に際して取り外さなければならないのは上述したとおりである。この取外しや取付けには工具を使うが、本発明では、パネル押え４を次のような構成にし、これを操作するに好ましい工具として次のような専用工具を提案する。まず、パネル押え４であるが、図４の説明図で示されるように、本発明では、ドライバーや六角レンチといった汎用工具に形成される汎用係合部には非係合であって、後述する専用工具２３に形成される専用係合部２３ｃには係合する専用係合形状４ａが形成されるとともに、その間に汎用係合部を非係合とする汎用非係合形状４ｂが形成されたものである。 By the way, as described above, the floor panel 1 fixed to the support leg 2 as described above must be removed for maintenance or layout change. Although a tool is used for this removal and attachment, in the present invention, the panel retainer 4 is configured as follows, and the following dedicated tool is proposed as a preferable tool for operating this. First, as shown in the explanatory view of FIG. 4, the panel presser 4 is not engaged with a general-purpose engaging portion formed on a general-purpose tool such as a screwdriver or a hexagon wrench, as will be described later. The dedicated engagement portion 23c formed in the dedicated tool 23 is formed with a dedicated engagement shape 4a to be engaged, and a general-purpose non-engagement shape 4b in which the general-purpose engagement portion is disengaged is formed therebetween. Is.
専用係合形状４ａとしては、頭部１６の上面に汎用係合部よりも大形の多角形穴が形成されるのが一般的であるが、本例では、正三角形の各頂点を中心に他の二点を結ぶ外膨した円弧状の辺部で囲まれた平面視おむすび形の三角穴４ａａとしている（この形状は一例であり、これに限定されるものではない）。一方、汎用非係合形状４ｂとしては、孔のようなものが一般的であるが、本例では、三角穴４ａａの底部からネジ穴１７ａに貫通する円筒形の逃がし孔４ｂａとしている。この場合の汎用係合部は、以下に述べる専用工具２３の汎用係合部２３ｄに限らず、一般的な汎用工具に形成された汎用係合部をも含むものである。 As the exclusive engagement shape 4a, a polygonal hole that is larger than the general-purpose engagement portion is generally formed on the upper surface of the head 16, but in this example, each vertex of the equilateral triangle is the center. A plan view rice ball-shaped triangular hole 4aa surrounded by an outwardly expanded arc-shaped side portion connecting the other two points (this shape is an example, and is not limited thereto). On the other hand, the general-purpose non-engaging shape 4b is generally a hole, but in this example, it is a cylindrical relief hole 4ba penetrating from the bottom of the triangular hole 4aa to the screw hole 17a. The general-purpose engaging portion in this case is not limited to the general-purpose engaging portion 23d of the dedicated tool 23 described below, but also includes a general-purpose engaging portion formed on a general general-purpose tool.
以上のパネル押え４は、その専用係合形状４ａには汎用係合部が非係合ではあるものの、専用係合部２３ｃが係合できるのであるが、これに加えてその汎用非係合形状４ｂにも汎用係合部２３ｄが非係合であるから、前者が後者より上方にあって、かつ汎用係合部２３ｄが係合できない大形のものが一般的である。このように、本発明におけるパネル押え４には、汎用非係合部４ｂが汎用係合部２３ｄが係合できない意図をもって、しかも積極的に形成されているのが特徴である。 The above-mentioned panel presser 4 can be engaged with the dedicated engaging portion 23c, although the general-purpose engaging portion is not engaged with the dedicated engaging shape 4a. Since the general-purpose engaging portion 23d is also non-engaged in 4b, a large size is generally available in which the former is above the latter and the general-purpose engaging portion 23d cannot be engaged. As described above, the panel retainer 4 according to the present invention is characterized in that the general-purpose non-engaging portion 4b is actively formed with the intention that the general-purpose engaging portion 23d cannot be engaged.
次に専用工具２３であるが、この専用工具２３は、上記した専用係合形状４ａが形成されたセキュリティー仕様のものと、汎用係合形状のみが形成された通常仕様のものの両方が操作できるものになっている。図１等にそれが示されるが、この専用工具２３には、上部から握り部２３ａ、本体部２３ｂ、専用係合部２３ｃ、汎用係合部２３ｄが形成されている。このうち、握り部２３ａは操作するときに握ったり、レンチを嵌合する部分で、本体部２３ｂは主体をなす部分である。 Next, the dedicated tool 23, which can be operated by both the security specification in which the exclusive engagement shape 4a is formed and the normal specification in which only the general-purpose engagement shape is formed. It has become. As shown in FIG. 1 and the like, the dedicated tool 23 is formed with a grip portion 23a, a main body portion 23b, a dedicated engagement portion 23c, and a general-purpose engagement portion 23d from above. Of these, the grip portion 23a is a portion where a grip or a wrench is fitted when operating, and the main body portion 23b is a main portion.
また、専用係合部２３ｃは、上記したセキュリティー仕様のパネル押え４に形成された三角穴（専用係合形状）４ａａに係合する部分であり、これと同じ形状をしているものである。これに対して、汎用係合部２３ｄは、マイナス（プラス）溝や六角穴といった汎用係合形状に係合する部分で、本例では、マイナスドライバー２３ｄとなっている。図５は通常仕様のパネル押え４に対する専用工具２３の作用を示す説明図であるが、このマイナスドライバー（汎用係合部）２３ｄは、パネル押え４に形成されたマイナス溝（汎用係合形状）にも係合できてこれを操作できる。 The exclusive engagement portion 23c is a portion that engages with a triangular hole (dedicated engagement shape) 4aa formed in the panel presser 4 of the security specification described above, and has the same shape as this. On the other hand, the general-purpose engaging portion 23d is a portion that engages with a general-purpose engaging shape such as a minus (plus) groove or a hexagonal hole, and is a minus driver 23d in this example. FIG. 5 is an explanatory view showing the operation of the dedicated tool 23 for the panel presser 4 of the normal specification. The flat screwdriver (general-purpose engaging portion) 23d is a negative groove (general-purpose engaging shape) formed in the panel presser 4. Can be engaged and operated.
したがって、これ一本で、セキュリティー仕様と通常仕様のパネル押え４の両方を操作できるものとなる。もちろん、一般的な汎用工具としても利用できる。このようにセキュリティー仕様と通常仕様のパネル押え４に対して支持脚３は共通のものが使用できるため、将来、レイアウト変更等により専用部分と共通部分の区画に変更があった場合でも、パネル押え４を別の仕様のものに取り換えるだけでセキュリティーを付加したり、解除したりできる。 Therefore, with this one, both the security specification and the normal specification panel presser 4 can be operated. Of course, it can also be used as a general-purpose tool. As described above, since the support leg 3 can be used in common with the panel presser 4 of the security specification and the normal specification, the panel presser can be used even if the section between the dedicated part and the common part is changed due to a layout change or the like in the future. Security can be added or removed simply by replacing 4 with a different one.
ところで、以上の専用係合形状４ａ、汎用係合形状、専用係合部２３ｃ及び汎用係合部２３ｄとには次のような関係がある。まず、専用工具２３には専用係合部２３ｃと汎用係合部２３ｄの両方が形成されていることから、セキュリティー仕様のパネル押え４に形成される専用係合形状４ａに対しては汎用係合部２３ｄでは係合できないことになる。この場合の汎用係合部２３ｄはこの専用工具２３に形成されたものに限らず、一般的な汎用工具に形成された汎用係合部をも含むものである。次に、この汎用係合部２３ｄを非係合とする汎用非係合形状４ｂが形成されていることであり、この汎用非係合形状４ｂは、上記の例でいえば、三角穴４ａａの底部に汎用係合部２３ｄの働きをスポイルするネジ穴１７ａに貫通する逃がし孔４ｂａということになる。 By the way, the above-mentioned exclusive engagement shape 4a, general-purpose engagement shape, exclusive-engagement portion 23c, and general-purpose engagement portion 23d have the following relationship. First, since the dedicated tool 23 is formed with both the dedicated engagement portion 23c and the general-purpose engagement portion 23d, the general-purpose engagement is performed on the dedicated engagement shape 4a formed on the panel presser 4 of the security specification. The portion 23d cannot be engaged. The general-purpose engaging portion 23d in this case is not limited to the one formed on the dedicated tool 23, but also includes a general-purpose engaging portion formed on a general general-purpose tool. Next, the general-purpose non-engaging shape 4b that disengages the general-purpose engaging portion 23d is formed, and the general-purpose non-engaging shape 4b is, for example, the triangular hole 4aa. This is the relief hole 4ba penetrating through the screw hole 17a that spoils the function of the general-purpose engaging portion 23d at the bottom.
図６はセキュリティー仕様のパネル押え４に対する汎用工具の作用を示す説明図であるが、逃がし孔４ｂａには挿入できないが、三角穴４ａａには差し込める最大幅のマイナスドライバー形状の汎用係合部２４を備えた汎用工具を使用してパネル押え４を図中矢印方向に回転させて取り外そうとすることが考えられる（図６（ａ）の状態）。しかし、汎用係合部２４は図６（ｂ）や（ｃ）に示すように、三角穴４ａａの辺に沿って滑るだけで、係合させることはできないから、三角穴４ａａはセキュリティーを確保していることになる。 FIG. 6 is an explanatory view showing the action of the general-purpose tool on the panel presser 4 of the security specification, but it cannot be inserted into the escape hole 4ba, but the maximum-width minus driver-shaped general-purpose engaging portion 24 that can be inserted into the triangular hole 4aa. It is conceivable that the panel presser 4 is rotated in the direction of the arrow in the drawing using a general-purpose tool provided with a (FIG. 6 (a) state). However, as shown in FIGS. 6B and 6C, the general-purpose engaging portion 24 simply slides along the side of the triangular hole 4aa and cannot be engaged, so the triangular hole 4aa ensures security. Will be.
図７はパネル押え４の他の例を示す説明図であるが、本例のものは、三角穴（専用係合形状）４ａａがそのままネジ穴１７ａに貫通しているもので、専用係合形状４ａと汎用非係合形状４ｂとが兼用されたものである。成形が簡単になって製作コストが安くなるのが利点である。これによると、専用工具２３の専用係合部２３ｃは三角穴４ａａには係合するが、汎用工具の汎用係合部は係合できない上に、ネジ穴（汎用非係合形状）１７ａによってその働きがスポイルされる。 FIG. 7 is an explanatory view showing another example of the panel retainer 4, but in this example, the triangular hole (dedicated engagement shape) 4aa passes through the screw hole 17a as it is. 4a and the general-purpose non-engaging shape 4b are combined. The advantage is that molding is simplified and manufacturing costs are reduced. According to this, the dedicated engaging portion 23c of the dedicated tool 23 engages with the triangular hole 4aa, but the general-purpose engaging portion of the general-purpose tool cannot be engaged, and the screw hole (general-purpose non-engaging shape) 17a The work is spoiled.
図８はパネル押え４と専用工具２３の更に他の例を示す説明図であるが、本例のパネル押え４の専用係合形状４ａは、頭部１６の上面に中心から等距離に複数（本例では二個）の係合穴４ａｂが形成されたものであり、汎用非係合形状４ｂは、中心にネジ穴に貫通する逃がし穴４ｂａが形成されたものである。したがって、専用工具２３は、本体部２３ｂが円板体であり、その下面に係合穴４ａｂに嵌合するピン２３ｃａが突設されたものである。これによっても、汎用工具の汎用係合部はピン２３ｃａには係合できず、しかも逃がし穴４ｂａに嵌まり込んで機能を果たせない。 FIG. 8 is an explanatory view showing still another example of the panel retainer 4 and the dedicated tool 23, but there are a plurality of dedicated engagement shapes 4a of the panel retainer 4 of this example at an equal distance from the center on the upper surface of the head 16. In this example, two engagement holes 4ab are formed, and the general-purpose non-engagement shape 4b is formed with a relief hole 4ba penetrating the screw hole at the center. Therefore, the dedicated tool 23 has a main body 23b that is a disc body, and a pin 23ca that fits into the engagement hole 4ab is provided on the lower surface thereof. Also by this, the general-purpose engaging portion of the general-purpose tool cannot be engaged with the pin 23ca, and furthermore, it cannot be fitted into the escape hole 4ba and perform its function.
