Description

本考案は、金属管製の脚部を有するハンガーラックに関する。 The present invention relates to a hanger rack having legs made of a metal tube.

図１及び図２に、従来のハンガーラックを示す。
ハンガーラックの下端両側には、弓形に湾曲した金属管２１と、その両端部に装着された一対のキャスタ２３とから成る脚部２０を設ける。
金属管２１の両端寄りの下面にはそれぞれ係止孔２１１を形成し、係止孔２１１にＴナット２２を埋め込む。Ｔナット２２の一端外周にはフランジ２２２が形成され、このフランジ２２２を金属管２１の下面に溶接してある。
また、Ｔナットには中心軸に沿ってネジ孔２２１を形成し、キャスタ２３の上方へ突出するネジ軸２３１をＴナット２２のネジ孔２２１へ螺合して、キャスタ２３を金属管２１へ取りつけてある。 1 and 2 show a conventional hanger rack.
On both sides of the lower end of the hanger rack, there are provided legs 20 each comprising a metal tube 21 curved in an arc shape and a pair of casters 23 attached to both ends thereof.
Lock holes 211 are formed in the lower surface near both ends of the metal tube 21, and the T nut 22 is embedded in the lock holes 211. A flange 222 is formed on the outer periphery of one end of the T nut 22, and the flange 222 is welded to the lower surface of the metal tube 21.
A screw hole 221 is formed in the T nut along the central axis, and a screw shaft 231 projecting upward from the caster 23 is screwed into a screw hole 221 of the T nut 22, and the caster 23 is attached to the metal tube 21. It is.

ところが、キャスタ２３のネジ軸２３１は垂直に設置しなければならないので、弓形に湾曲した金属管２１とＴナット２２のフランジ２２２とは、内側（金属管２１の頂部側）が広くなるような角度を持って交差することになる。
このため、溶接作業が困難で、Ｔナット２２が傾き易いばかりでなく、溶接の大部分がＴナット２２の内側に偏るので、内側に大きな溶接痕Ａが形成され、Ｔナット２２と金属管２１の接触面が不均等になり、外力が加わると、キャスタ２３が容易に湾曲してしまう。 However, since the screw shaft 231 of the caster 23 has to be installed vertically, the metal tube 21 curved in an arc shape and the flange 222 of the T-nut 22 have an angle such that the inside (top side of the metal tube 21) is widened. Will have to cross.
For this reason, the welding operation is difficult, and not only is the T-nut 22 easily tilted, but also most of the welding is biased inside the T-nut 22, so that a large welding mark A is formed inside, and the T-nut 22 and the metal pipe 21 When the contact surface becomes uneven and an external force is applied, the casters 23 are easily bent.

本考案が解決しようとする課題は、金属管の両端寄り下面に装着されたキャスタに加わる力を平均化し、キャスタを支持するＴナットを金属管に溶接しやすいハンガーラックを提供することにある。 A problem to be solved by the present invention is to provide a hanger rack in which a force applied to a caster mounted on a lower surface near both ends of a metal tube is averaged, and a T-nut supporting the caster is easily welded to the metal tube.

本考案のハンガーラックは、上方へ凸に湾曲した略弓形の金属管と、その両端部に装着された一対のキャスタとから成る脚部を有し、前記金属管の両端部下面に、水平下面を有する溶接座部を形成すると共に、該溶接座部の水平下面に係止孔を形成し、Ｔ形ナットを前記係止孔に挿入すると共に、該Ｔ形ナットの下端外周に水平に張りだしたフランジを前記溶接座部の水平下面に溶接し、前記キャスタの上方に突出したネジ軸を、前記Ｔ形ナットの中心軸に沿って形成されたネジ孔に螺合してある。 The hanger rack of the present invention has legs formed of a substantially arcuate metal tube curved convexly upward and a pair of casters mounted on both ends of the hanger rack. And a locking hole is formed in the horizontal lower surface of the welding seat, a T-shaped nut is inserted into the locking hole, and the T-shaped nut is horizontally stretched around the lower end of the T-shaped nut. The welded flange is welded to the horizontal lower surface of the welding seat, and a screw shaft protruding above the caster is screwed into a screw hole formed along a central axis of the T-shaped nut.

本考案によれば、金属管の下面に、水平下面を有する溶接座部を形成し、キャスタを取りつけるためのＴ形ナットのフランジを溶接座部の水平下面に溶接してあるので、Ｔ形ナットを簡単に、且つ、正確な角度に溶接することができ、また、キャスタに加わる外力が平均して分散され、このため、キャスタの破損や変形を防ぐことができて、耐久性が向上する。 According to the present invention, a welding seat having a horizontal lower surface is formed on the lower surface of the metal pipe, and the flange of the T-shaped nut for mounting the caster is welded to the horizontal lower surface of the welding seat. Can be welded easily and at an accurate angle, and the external force applied to the casters is dispersed evenly, so that the casters can be prevented from being damaged or deformed, and the durability is improved.

以下、本考案の実施例を、図面に基づいて詳細に説明する。なお、ハンガーラックはほぼ左右対称なので、図面にはハンガーラックの一側下部のみを示す。
図３及び図４に示すように、ハンガーラックの下端両側には、上方へ凸に湾曲した略弓形の金属管１１と、その両端部に装着された一対のキャスタ１３とから成る脚部をそれぞれ設ける。
金属管１１の両端部下面をプレス成形により下方へ突出させて、水平下面１１０１を有する溶接座部１１０を形成する。溶接座部１１０の水平下面１１０１には、係止孔１１０２を形成してある。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Since the hanger rack is almost symmetrical, only one lower portion of the hanger rack is shown in the drawing.
As shown in FIG. 3 and FIG. 4, on both sides of the lower end of the hanger rack, a substantially arc-shaped metal tube 11 curved upward and convex and a pair of casters 13 attached to both ends thereof are provided with legs, respectively. Provide.
The lower surfaces of both ends of the metal tube 11 are projected downward by press molding to form a welding seat 110 having a horizontal lower surface 1101. A locking hole 1102 is formed in the horizontal lower surface 1101 of the welding seat 110.

金属管１１の係止孔１１０２には、金属製のＴ形ナット１２を下方から挿入する。
Ｔ形ナット１２は、その中心軸に沿ってネジ孔１２２を有すると共に、Ｔ形ナット１２の下端外周には、係止孔１１０２よりも径大のフランジ１２１を水平方向に張りだしてあり、このフランジ１２１を溶接座部１１０の水平下面１１０１に密着させて溶接することにより、Ｔ形ナット１２を金属管１１に取りつける。
キャスタ１３は、断面半円状に湾曲した支持具１３２の下方に回動自在に支持され、支持具１３２の頂部上面にはネジ軸１３１を突設する。
そして、ネジ軸１３１をＴ形ナット１２のネジ孔１２２に螺じ込んで、キャスタ１３を金属管２１に取りつける。 A metal T-shaped nut 12 is inserted into the locking hole 1102 of the metal tube 11 from below.
The T-shaped nut 12 has a screw hole 122 along the center axis thereof, and a flange 121 having a diameter larger than that of the locking hole 1102 is protruded horizontally around the lower end of the T-shaped nut 12. The T-shaped nut 12 is attached to the metal pipe 11 by welding the flange 121 in close contact with the horizontal lower surface 1101 of the welding seat 110.
The caster 13 is rotatably supported below a support 132 that is curved in a semicircular cross section, and a screw shaft 131 protrudes from the top surface of the support 132.
Then, the screw shaft 131 is screwed into the screw hole 122 of the T-shaped nut 12, and the caster 13 is attached to the metal tube 21.

金属管１１の溶接座部１１０の水平下面１１０１に、Ｔ形ナット１２のフランジ１２１を溶接し、Ｔ形ナット１２のネジ孔１２２にネジ軸１３１を螺合して、キャスタ１３を取りつけてあるので、キャスタ１３のネジ軸１３１を垂直に起立させ易く、金属管１１とＴ形ナット１２との溶接作業も容易となる。
また、溶接部は溶接座部１１０の水平下面１１０１とＴ形ナット１２のフランジ１２１との間にほぼ均一に形成されるので、体裁も良く、キャスタ１３に加わる外力が分散されて、キャスタ１３の変形や破損を防ぐことができ、耐久性が向上する。 Since the flange 121 of the T-shaped nut 12 is welded to the horizontal lower surface 1101 of the welding seat 110 of the metal tube 11, the screw shaft 131 is screwed into the screw hole 122 of the T-shaped nut 12, and the caster 13 is attached. In addition, the screw shaft 131 of the caster 13 can be easily erected vertically, and the welding operation of the metal tube 11 and the T-shaped nut 12 can be easily performed.
Further, since the welded portion is formed substantially uniformly between the horizontal lower surface 1101 of the welding seat 110 and the flange 121 of the T-shaped nut 12, the appearance is good, and the external force applied to the caster 13 is dispersed, Deformation and breakage can be prevented, and durability is improved.
