ボルト回し具係合部１３は、ボルト１１に後付けされたものでもよいが、図示例ではボルト１１と一体的に形成されており、平面形状が６角形のものである。側周面に互いに平行な面部分を有する６角形ボルト頭や６角形ナットなどに係合して回し操作できるスパナ型レンチ、回し対象物を掴む顎の間隔を調節できる所謂モンキーレンチ等のボルト回し具（図示省略）をボルト回し具係合部１３に係合させてボルト１１を回し操作できる。 The bolt turning tool engaging portion 13 may be retrofitted to the bolt 11, but is formed integrally with the bolt 11 in the illustrated example and has a hexagonal planar shape. A bolt wrench such as a hexagonal bolt head or a hexagonal nut having side surfaces parallel to each other on the side peripheral surface, which can be rotated and operated, and a so-called monkey wrench that can adjust the distance between jaws for gripping the object to be rotated. A tool (not shown) can be operated by turning the bolt 11 by engaging the tool (not shown) with the bolt turning tool engaging portion 13.
ボルト台座１２はこの例では平面から見た形状が円形であり、碗を伏せた如き形状、構造のものである。ボルト１１はこの例ではボルト回し具係合部１３の下へも若干突出しており、その突出部１１２がボルト台座１２の頂部貫通孔１２１を貫通して台座１２の下面側凹所１２２へ突出している。 In this example, the bolt pedestal 12 has a circular shape when viewed from the plane, and has a shape and structure as if the heel is turned down. In this example, the bolt 11 protrudes slightly below the bolt turning tool engaging portion 13, and the protruding portion 112 passes through the top through hole 121 of the bolt base 12 and protrudes into the lower surface side recess 122 of the base 12.

The bolt 11 can be rotated by engaging a bolt driver such as a spanner wrench (not shown) with the bolt driver engaging portion 13 as necessary.
以上説明した類の物品支持脚は例えば特許第３０３５４７４号公報や特許第３１２９９０５号公報に記載されている。
これら特許公報に記載された物品支持脚ではボルト回し具係合部とボルト台座との間にスラストベアリングが嵌装されている。
Article support legs of the kind described above are described in, for example, Japanese Patent No. 3035474 and Japanese Patent No. 3129905.
In the article support legs described in these patent publications, a thrust bearing is fitted between the bolt driver engaging portion and the bolt base.
以上説明した物品支持脚１によると、ボルト台座１２は物品支持基体４上に配置されているだけであるから、必ずしもその位置が安定しているとは言い難い。例えば、物品３の傍を他の物品が搬送されるとき、それが衝突して位置ずれしたり、物品３の運転に振動を伴う場合、その振動のために位置ずれしたりする等のおそれがある。 According to the article support leg 1 described above, the bolt pedestal 12 is merely disposed on the article support base 4, so it is not necessarily said that the position is stable. For example, when another article is transported near the article 3, it may cause a position shift due to a collision, or when the operation of the article 3 involves vibration, the position may be shifted due to the vibration. is there.
そのため、図４及び図５に例示するごとき物品支持脚用の脚止め具が提案され、実用に供されている。 Therefore, a leg stopper for an article support leg as exemplified in FIGS. 4 and 5 has been proposed and put into practical use.
図４及び図５に示す脚止め具２’は、前記のボルト回し具係合部１３に脱離可能に外嵌可能の二股部２１’と、物品支持基体４に固定されるべき固定部２２’と、二股部２１’と固定部２２’とに跨がって二股部２１’及び固定部２２’と一体的に形成された中間部２３’とを含んでいる。 The leg stopper 2 ′ shown in FIGS. 4 and 5 includes a bifurcated portion 21 ′ that can be detachably fitted to the bolt driver engaging portion 13 and a fixing portion 22 to be fixed to the article support base 4. And an intermediate portion 23 ′ formed integrally with the bifurcated portion 21 ′ and the fixed portion 22 ′ across the bifurcated portion 21 ′ and the fixed portion 22 ′.
二股部２１’は、内側面が平行な対をなす面２１１’、２１２’と、それらをつなぐ、平面からみると円弧形状の奥側面２１３’とで形成されているものである。 The bifurcated portion 21 ′ is formed by a pair of surfaces 211 ′ and 212 ′ whose inner side surfaces are parallel to each other, and an arcuate rear side surface 213 ′ that connects them, as viewed from the plane.
図４に例示するように被支持物品３を物品支持基体４の定位置に支持している物品支持脚１は、脚止め具２’の二股部２１’をボルト回し具係合部１３に外嵌係合する一方、脚止め具２’の固定部２２’をその孔２２ｈ’に通したアンカーボルト５で基体４に固定することで、前記定位置により安定的に固定されるとともにボルト回し具係合部１３の不測の回動が防止され、それだけ安定的に物品３を支持することができる。 As shown in FIG. 4, the article support leg 1 supporting the article 3 to be supported at a fixed position on the article support base 4 has the bifurcated portion 21 ′ of the leg stopper 2 ′ outside the bolt driver engaging portion 13. On the other hand, the fixing portion 22 ′ of the leg stopper 2 ′ is fixed to the base body 4 with the anchor bolt 5 passed through the hole 22h ′, so that it is stably fixed at the fixed position and the bolt driver. The unexpected rotation of the engaging portion 13 is prevented, and the article 3 can be supported stably as much.
前記した従来タイプの脚止め具２’は、その二股部２１’を物品支持脚１のボルト回し具係合部１３に嵌合させる操作を容易化するため、例えば、ボルト回し具係合部１３が図４、図５の係合部１３のように、二股部２１’が外嵌係合できる互いに平行な面部分１３１、１３１（図４参照）を有するものである場合、二股部２１’の対向平行面２１１’、２１２’間の間隔Ａは、係合部１３の平行面部分１３１、１３１の間隔ｄより若干大きくしてある。例えば、間隔ｄが２４ｍｍとすると、間隔Ａは２４．５ｍｍ〜２５ｍｍ程度である。 In order to facilitate the operation of fitting the bifurcated portion 21 ′ into the bolt driver engaging portion 13 of the article support leg 1, the conventional type of leg stopper 2 ′ described above is, for example, a bolt driver engaging portion 13. 4 and 5, when the bifurcated portion 21 ′ has parallel surface portions 131 and 131 (see FIG. 4) that can be fitted and engaged, the bifurcated portion 21 ′ An interval A between the opposed parallel surfaces 211 ′ and 212 ′ is slightly larger than an interval d between the parallel surface portions 131 and 131 of the engaging portion 13. For example, when the distance d is 24 mm, the distance A is about 24.5 mm to 25 mm.
そのため、脚止め具２’の二股部２１’と物品支持脚１のボルト回し具係合部１３との間に隙間があり、それにより二股部２１’が係合部１３に対してガタつくおそれがある。しかしそのようなガタツキは抑制して物品支持脚１をより定位置に安定化させることが好ましい。 Therefore, there is a gap between the bifurcated portion 21 ′ of the leg stopper 2 ′ and the bolt driver engaging portion 13 of the article support leg 1, which may cause the bifurcated portion 21 ′ to rattle with respect to the engaging portion 13. There is. However, it is preferable to suppress such rattling and stabilize the article support leg 1 in a more fixed position.
そこで本発明は、雄ねじを形成したボルトがボルト台座に回転自在に立設されており、該ボルトの雄ねじ部分を被支持物品のボルト螺合部位に螺合させ、該ボルト螺合部位からのボルト突出量を調整するとともに該ボルト台座を物品支持基体上に配置することで該物品を該物品支持基体上に支持することができ、前記ボルトの前記ボルト台座に隣り合う部位にボルト回し具係合部が設けられている物品支持脚のための脚止め具であり、前記ボルト回し具係合部に脱離可能に外嵌可能の二股部と、前記物品支持基体に固定されるべき固定部と、前記二股部と前記固定部とにわたって該二股部及び固定部と一体的に形成された中間部とを含んでいる脚止め具であって、次の利点を有する脚止め具を提供することを課題とする。
すなわち、従来の同種の脚止め具と比較すると、二股部をガタツキが抑制される状態で物品支持脚のボルト回し具係合部に嵌めることができ、それにより物品支持脚を物品支持基体の定位置に安定化させることができるとともにボルト回し具係合部の不測の回動をより確実に阻止でき、それらにより全体として安定的に物品支持脚に被支持物品を支持させておくことができる脚止め具である。

バネ部分２４１、２４２のそれぞれは二股部本体２１０の対をなしている部分２１１、２１２のそれぞれの先端外面上へ回り込んだ部分２４１ａ、２４２ａを含んでいる。それら部分２４１ａ、２４２ａで二股部本体部分２１１、２１２のそれぞれの先端外面に連結されているとともにバネ部分２４３の中央部分で二股部本体の奥部分２１３に連結されている。この例ではこのように合計３箇所で二股部本体に連結されている。 Each of the spring portions 241 and 242 includes portions 241a and 242a that wrap around the outer surfaces of the respective tips of the portions 211 and 212 forming a pair of the bifurcated body 210. These portions 241a and 242a are connected to the outer front surfaces of the bifurcated body portions 211 and 212, and are connected to the back portion 213 of the bifurcated body at the central portion of the spring portion 243. In this example, it is thus connected to the bifurcated body at three places in total.
バネ２４の前記各箇所での連結は螺子止め等の止め部材を用いて行われてもよいが、本例では溶接にて連結されている。
なお、図示はしていないが、バネ部分２４３の二股部本体奥部分２１３への連結を省略して残りの２箇所だけで連結してもよいが、図示例ではバネ２４を二股部本体２１０により安定的に配置するために前記のように３箇所で連結している。
The connection of the spring 24 at each of the above locations may be performed using a stopper member such as a screw, but in this example, the connection is made by welding.
Although not shown, the connection of the spring portion 243 to the back portion 213 of the bifurcated body may be omitted and the two portions may be connected at the remaining two locations. In order to arrange stably, it connects with three places as mentioned above.
以上説明した脚止め具２によると、従来の脚止め具と同様に例えば図３に示されるように被支持物品３を物品支持基体（床等）４の定位置に支持している物品支持脚１のボルト回し具係合部１３に、従来の脚止め具２’の場合と同様に二股部２１を外嵌係合させる一方、固定部２２をそのアンカーボルト通し孔２２ｈに通したアンカーボルト５で物品支持基体４に固定することができる。 According to the leg stopper 2 described above, as in the conventional leg stopper, as shown in FIG. 3, for example, the article support leg that supports the supported article 3 at a fixed position on the article support base (floor or the like) 4. As with the conventional leg stopper 2 ′, the two forks 21 are fitted and engaged with the bolt turner engaging portion 1, while the fixing bolt 22 is passed through the anchor bolt through hole 22 h. Can be fixed to the article support substrate 4.
しかし脚止め具２によると、その二股部本体２１０の内側面にそって上記のとおり屈曲帯状板バネ２４を配置してあるから、二股部２１を物品支持脚１のボルト回し具係合部１３に外嵌係合させるとき、板バネ２４をその弾力に抗して変形させつつ外嵌係合させることになる。二股部２１がボルト回し具係合部１３に外嵌係合した状態では、弾性変形した板バネ２４の部分２４１、２４２（二股部本体２１０の対部分２１１、２１２にそった部分２４１、２４２）が、板バネ２４の弾性復元力のもとにボルト回し具係合部１３をしっかりと挟着する。 However, according to the leg stopper 2, since the bent belt spring 24 is arranged along the inner surface of the bifurcated main body 210, the bifurcated portion 21 is connected to the bolt driver engaging portion 13 of the article support leg 1. When externally engaging with each other, the leaf spring 24 is externally engaged while being deformed against its elasticity. In a state where the bifurcated portion 21 is externally engaged with the bolt driver engaging portion 13, the elastically deformed portions 241 and 242 of the leaf spring 24 (portions 241 and 242 along the paired portions 211 and 212 of the bifurcated main body 210). However, the bolt driver engaging portion 13 is firmly clamped under the elastic restoring force of the leaf spring 24.
このように、脚止め具２は、従来の同種の脚止め具２’と比較すると、二股部本体２１０の内側面にそって配置された屈曲帯状板バネ２４により二股部２１がガタツキが抑制される状態で物品支持脚１のボルト回し具係合部１３にしっかりと外嵌係合することができ、それにより従来の脚止め具２’より物品支持脚１を物品支持基体４の定位置に安定化させることができるとともにボルト回し具係合部１３の不測の回動をより確実に阻止でき、それらにより全体として安定的に物品支持脚１に被支持物品３を支持させておくことができる。 As described above, the leg stopper 2 is less likely to rattle the bifurcated portion 21 by the bent belt spring 24 arranged along the inner surface of the bifurcated main body 210 as compared with the conventional leg stopper 2 'of the same type. In this state, it is possible to firmly fit and engage with the bolt turning tool engaging portion 13 of the article support leg 1 so that the article support leg 1 is positioned at a fixed position of the article support base 4 from the conventional leg stopper 2 '. As well as being able to stabilize, the unexpected rotation of the bolt driver engaging portion 13 can be more reliably prevented, and the supported article 3 can be supported stably on the article support leg 1 as a whole. .
本発明は、雄ねじを形成したボルトがボルト台座に回転自在に立設されており、該ボルトの雄ねじ部分を被支持物品のボルト螺合部位に螺合させ、該ボルト螺合部位からのボルト突出量を調整するとともに該ボルト台座を物品支持基体上に配置することで該物品を該物品支持基体上に支持することができ、前記ボルトの前記ボルト台座に隣り合う部位にボルト回し具係合部が設けられている物品支持脚のための、該ボルト回し具係合部に外嵌係合する脚止め具を提供することに利用できる。According to the present invention, a bolt having a male screw is erected on a bolt base so as to be rotatable, and a male screw portion of the bolt is screwed into a bolt screwing portion of a supported article so that the bolt protrudes from the bolt screwing portion. By adjusting the amount and disposing the bolt pedestal on the article support base, the article can be supported on the article support base, and a bolt driver engaging portion is provided at a portion of the bolt adjacent to the bolt pedestal. Can be used to provide a leg stopper that is externally engaged with the bolt driver engaging portion for an article support leg provided with a bolt.
