Description

【０００１】
【発明の属する技術分野】
本発明は、例えばコンデンサやスイッチ等の被固定物をレールに着脱可能に取付ける際に用いられる取付金具の改良に関する。
【０００２】
【従来の技術】
従来、この種の取付金具としては、例えば実公平７−２４６４３号や実公平７−２４６４５号等に記載された固定フック型のものと、実公平６−４５２１号や実開平５−３３４１８号や実開平５−７３９８６号や実開平５−９０９３１号や特開２００１−１１９１５６号等に記載された可動フック型のものが知られている。
【０００３】
前者のものは、基本的には、レールの上方に位置される本体と、本体の一側に設けられてレールの同側の鍔部に係合可能な長い鉤部と、本体の他側に設けられてレールの同側の鍔部に係合可能な短い鉤部と、本体に設けられてレールに対する本体の移動を阻止する締付具と、から構成されたものであり、長い鉤部をレールの一方の鍔部に係合させた後に、短い鉤部をレールの他方の鍔部に係合させ、締付具に依り両鉤部と両鍔部の係合が保たれる様になっている。
【０００４】
後者のものは、基本的には、レールの上方に位置される本体と、本体の一側に設けられてレールの同側の鍔部に係合可能な固定鉤部と、本体の他側に移動可能に設けられてレールの同側の鍔部に係合可能な可動鉤部と、から構成されたものであり、固定鉤部をレールの一方の鍔部に係合させた後、可動鉤部を移動させる事に依り可動鉤部をレールの他方の鍔部に係合させる様になっている。
【０００５】
【発明が解決しようとする課題】
ところが、何れのものも、両鉤部の形状が異なるので、左右対称形とはならず、製造が容易ではないと共に、レールに対して一方の鉤部を係合させた後に他方の鉤部を係合させる様にしているので、係合順序が一定化されて逆順序では取付ける事が叶わず、取付作業に汎用性がなかった。
本発明は、叙上の問題点に鑑み、これを解消する為に創案されたもので、その課題とする処は、製造が容易であると共に、取付作業に汎用性を持たせる様にした取付金具を提供するにある。
【０００６】
【課題を解決するための手段】
本発明の取付金具は、レールの上方に位置される本体と、本体の両側に左右対称形に形成されてレールの各鍔部に係合可能な左右の鉤部と、レールの上方に位置される取付体と、取付体の下部に左右対称形に形成されてレールに対して取付体を同芯位置に案内する案内溝と、本体と取付体との間に設けられて鉤部と案内溝とでレールの鍔部を挾持させる締付具と、から構成した事に特徴が存する。
【０００７】
本体と取付体との間に設けられる締付具に依り鉤部と案内溝とが大きく離間される様にして置く。そして、一方の鉤部がレールの一方の鍔部に係合された後、他方の鉤部がレールの他方の鍔部に係合される。次いで、締付具が締付けられ、鉤部と案内溝とでレールの鍔部が挾持される。この時、案内溝に依りレールに対して案内体が自動的に同芯位置に案内され、左右の鉤部と左右の鍔部との係合状態が均等化される。
左右の鉤部及び案内溝は、左右対称形に形成されているので、本体及び取付体も左右対称形に作製する事ができ、製造が容易となる。
左右の鉤部及び案内溝は、左右対称形に形成されているので、左右の鉤部のうちどちらからでもレールの鍔部に係合させる事ができ、係合順序を間違って取付不能に陥る惧れがない。つまり、取付作業に汎用性を与える事ができ、熟練者でなくても容易に取付作業が行なえる。
【０００８】
取付体は、断面略逆Ｕ型を呈し、内部には被固定物を取付ける為のボルトが螺合されて左右方向に移動可能で且つ所定位置に保持可能な左右のナット体が設けられていると共に、上壁にはボルトを挿通する左右方向に長い左右の長孔が形成されているのが好ましい。この様にすれば、取付位置が異なる被固定物であっても、ナット体の位置を変えるだけで取付ける事ができ、複数種類の取付金具を用意する必要がない。又、ナット体は、移動可能且つ所定位置に保持可能にしたので、ボルトとの螺合時には、これを保持する必要がなく、ボルトの螺合が容易に行なえる。

[0010]
The mounting bracket 1 is composed of a main body 2, a flange portion 3, a mounting body 4, a guide groove 5, and a fastening tool 6, and its main portion is used when fixing an object 8 to be fixed to the rail 7.
[0011]
In this example, the rail 7 is a DIN rail and is made of a metal such as an aluminum alloy. The rail 9 has a substantially U-shaped base 9 and left and right sides extending from the upper end thereof (FIG. 2). The right and left collars 10 and the base 9 are provided with a long hole 11 formed in the same direction at a predetermined interval with a predetermined interval.
That is, the rail 7 forms a base portion 9 with a bottom wall and left and right side walls extending upward from both left and right ends thereof, and also forms a flange portion 10 with left and right upper walls extending outward from the upper end of each side wall. There is a long hole 11 in the bottom wall.
The long hole 11 is for inserting a fixing tool (not shown) such as a screw or a bolt when the rail 7 is fixed to a predetermined mounting location.
[0012]
The fixed object 8 is a capacitor in this example, and includes mounting pieces 12 for vertical installation (three) and horizontal installation (two), which include bolts (spring washers and flat washers). Is provided with a mounting hole 14 for inserting a hexagonal bolt 13 fitted in advance.
[0013]
The main body 2 is positioned above the rail 7, and in this example, is made of a metal such as steel, has a substantially inverted U-shaped cross section, and is suspended from the upper wall 15 and both ends thereof. Side wall 16.
[0014]
The flange part 3 is formed on both sides of the main body 2 so as to be symmetric, and can be engaged with the flange parts 10 of the rail 7. In this example, the lower half center of the front and rear side walls 16 of the main body 2 is formed. It is formed by cutting in a substantially T shape, and a groove 17 is formed by each flange 3.
[0015]
The attachment body 4 is positioned above the rail 7 and is made of a metal such as an aluminum alloy in this example, has a substantially inverted U-shaped cross section, and is suspended from the upper wall 18 and both ends thereof. And front and rear side walls 19.

And a screw (dish screw) 24 to be joined.
[0018]
Thus, the distance between the outer ends of the flanges 10 of the rail 7 is A, the distance between the inner ends of the flanges 3 of the body 2 is B, and the distance between the flanges 17 of the body 2 is C. When the maximum distance of the guide groove 5 of the body 4 is D and the minimum distance of the guide groove 5 of the mounting body 4 is E, A <C, A> B, A <B + (C−B) / 2, C <D, A = E, and in practice, A = 35 mm, B = 32 mm, C = 39 mm, D = 40 mm, and E = 35 mm.
[0019]
Next, the operation will be described based on such a configuration.
The mounting body 4 is covered with the left and right nut bodies 20 from above the body 2 after the left and right nut bodies 20 are moved to a predetermined position in accordance with the interval between the mounting holes 14 of the fixed object 8 and held in the same state. And the screw 24 of the fastener 6 is inserted into the through-hole 23 and then screwed into the screw hole 22 so that the flange 3 of the main body 2 and the guide groove 5 of the mounting body 4 are greatly separated. It is made like.
From this state, as shown in FIG. 5, after one hook 3 is engaged with one hook 10 of the rail 7, the other hook 3 is connected to the rail 7 as shown in FIG. 4 through FIG. 6. The other hook 10 is engaged. At this time, since each dimension is set as described above, it is easily engaged.
Next, the screw 24 of the fastener 6 is tightened, and the flange portion 10 of the rail 7 is held between the flange portion 3 and the guide groove 5 as shown in FIG. At this time, the attachment body 4 is automatically guided to the concentric position with respect to the rail 7 by the guide groove 5, and the engagement state between the left and right flange portions 3 and the left and right flange portions 10 is equalized.
