Description

この発明は、組立式ワゴンに関するものである。とくに、この発明は棚板の位置変更が容易な金属製の組立式ワゴンに関するものである。   The present invention relates to an assembly-type wagon. In particular, the present invention relates to a metal assembly type wagon in which the position of the shelf board can be easily changed.

金属製の組立式ワゴンは公知である。公知の組立式ワゴンは支柱の構造によって2つに大別される。その1つは、支柱を4本に分離できるものであり、他の1つは2本の支柱が一体となった逆U字状又は門型の支柱を用いるものである。   Metal prefabricated wagons are known. Known assembly-type wagons are roughly classified into two types according to the structure of the columns. One of them can separate the struts into four, and the other one uses an inverted U-shaped or gate-shaped strut in which two struts are integrated.

逆U字状の支柱を用いるものは、例えば特開2000−153761号公報に記載されている。この公報は、逆U字状の支柱2個を対抗させて置き、対抗する支柱の下部を連結パイプで連結して四角枠を作り、枠の上部には平皿をさし渡し固定して枠体を構成し、こうして構成した枠体の各支柱の下端にキャスターを付設してワゴンとすることを記載している。この形式のワゴンは、重量の大きい物品を載せるには適していない。   A device using an inverted U-shaped support is described in, for example, Japanese Patent Application Laid-Open No. 2000-153761. In this publication, two inverted U-shaped struts are placed facing each other, a lower part of the opposite struts is connected by a connecting pipe to form a square frame, and a flat plate is inserted and fixed to the upper part of the frame. It is described that a caster is attached to the lower end of each column of the frame body thus configured to form a wagon. This type of wagon is not suitable for carrying heavy items.

分離された4本の支柱を用いる組立ワゴンは、例えば特開2006−122191号公報に記載されている。この公報は、支柱を山形鋼で作り、天板、底板及び棚板を何れも直角四辺形の浅い箱状にして、箱のかどに位置する側壁を山形鋼の内側にボルトで固定して枠体を作り、各支柱の下端にキャスターを付設してワゴンとすることを記載している。この形式のワゴンは重量の大きい物品を載せることができる。   An assembly wagon using four separated struts is described in, for example, Japanese Patent Application Laid-Open No. 2006-122191. This gazette is made of angle steel, and the top plate, bottom plate and shelf plate are all made into a shallow rectangular quadrilateral box, and the side wall located at the corner of the box is fixed to the inside of the angle steel with bolts It describes that the body is made and a caster is attached to the lower end of each column to form a wagon. This type of wagon can carry heavy items.

分離された4本の支柱を用いる形式のワゴンでは、各支柱を専ら山形鋼、すなわちアングル材で作り、棚板を専ら直角四辺形の浅い箱状体としてきた。従って、棚板を支柱に固定するには、天板や底板と同様に、ボルトとナットによる締め付けが行われた。その締め付けは1つの棚板について四隅にある2つの側壁を別々にアングルの各片に固定する必要があり、従って合計8個のボルトを締め付ける必要があった。そのため、棚板の付設には手間と時間がかかった。また棚板の位置変更には、8個のボルトを外し、さらに8個のボルトを締め付けなければならないことになり、従って一層煩瑣となった。そこで、この煩瑣を解消する必要があった。   In the wagon of the type using four separated struts, each strut is made entirely of angle steel, that is, an angle material, and the shelf board has been made into a shallow quadrilateral shallow box. Therefore, in order to fix the shelf board to the column, tightening with bolts and nuts was performed in the same manner as the top board and the bottom board. The tightening required two side walls at the four corners of one shelf to be fixed separately to each piece of the angle, and therefore a total of eight bolts had to be tightened. Therefore, it took time and effort to install the shelf board. Further, changing the position of the shelf board requires removing eight bolts and further tightening eight bolts, which makes it more cumbersome. Therefore, it was necessary to eliminate this annoyance.

他方、ワゴンではないが、棚板の付設と位置変更を容易にしたスチール棚が知られている。このスチール棚は、例えば実開平7−5442号公報に記載されている。この公報はスチール棚の支柱を横断面がL形の外板と、横断面が船底形の内板で構成している。詳しく言えば、その内板は、帯状板を長手方向に延びる2本の折線に沿って折曲して、中央片と中央片から135度の角度をなして起立する2つの側片で構成している。断面L形の外板は内板の外側から内板を被覆し、内板の側片から食み出した両側縁を内板に沿って折り返し、被覆して一体としたものを支柱としている。   On the other hand, although it is not a wagon, the steel shelf which made easy attachment of a shelf board and position change is known. This steel shelf is described in, for example, Japanese Utility Model Laid-Open No. 7-5442. In this publication, a steel shelf column is composed of an outer plate having an L-shaped cross section and an inner plate having a ship-bottom cross section. More specifically, the inner plate is composed of a central piece and two side pieces that stand at an angle of 135 degrees from the central piece by bending the belt-like plate along two fold lines extending in the longitudinal direction. ing. The outer plate having an L-shaped cross section covers the inner plate from the outside of the inner plate, and both side edges protruding from the side pieces of the inner plate are folded back along the inner plate to cover and form a single column.

この支柱では、内板の中央片に係止孔とビス挿通孔とを穿設し、係止孔に複雑な構造の棚板取付金具を係止し、棚板取付金具上に棚板を載せて棚板を付設することとしている。この構造では棚板取付金具を係止させるだけで棚板を付設することができるので、棚板の付設と位置変更が容易である。   In this support column, a locking hole and a screw insertion hole are formed in the center piece of the inner plate, a shelf mounting bracket having a complicated structure is locked in the locking hole, and the shelf plate is placed on the shelf mounting bracket. A shelf board will be attached. In this structure, since the shelf board can be attached only by locking the shelf board mounting bracket, it is easy to attach and change the position of the shelf board.

実開平7−5442号公報は、支柱の長手方向の端から端まで上述の外板と内板とで構成することとしている。従って、この公報によれば、支柱の端に位置する天板も底板も同じ棚板取付金具で固定することとなる。しかし、こうして作られたスチール棚は、形状が安定しなくて、横方向の力が加えられるとグラグラするものとなる。従って、このスチール棚はこれにキャスターを付設してワゴンとするに適していない。   Japanese Utility Model Laid-Open No. 7-5442 is composed of the above-described outer plate and inner plate from end to end in the longitudinal direction of the column. Therefore, according to this publication, the top plate and the bottom plate located at the end of the column are fixed with the same shelf mounting bracket. However, the steel shelves made in this way are not stable in shape and will become distorted when a lateral force is applied. Therefore, this steel shelf is not suitable for adding a caster to a wagon.

特開2000−153761号公報JP 2000-153761 A 特開2006−122191号公報JP 2006-122191 A 実開平7−5442号公報Japanese Utility Model Publication No. 7-5442

この発明は、上述のように分離された4本の支柱を用いる形式の組立ワゴンにおいて、棚板の付設及び位置変更を容易にしようとしてなされたものである。   The present invention is an assembly wagon of the type using four struts separated as described above, and is intended to facilitate attaching and changing the position of the shelf board.

この発明は、ワゴンにおいて天板と底板とを支柱に固定する手段は、従来通りボルトの締め付けによることとし、天板と底板との間に付設される棚板だけを、実開平7−5442号公報が提案している支柱によって固定することとした。   According to the present invention, in the wagon, the means for fixing the top plate and the bottom plate to the column is by tightening the bolts as before, and only the shelf plate provided between the top plate and the bottom plate is used in Japanese Utility Model Laid-Open No. 7-5442. It was decided to be fixed by the column proposed by the publication.

しかし、実開平7−5442号公報が提案する支柱は、内板から食み出している外板部分を折り返して、折り返し部分が内板内面を被覆するようにしただけで、内板と外板とを一体にしているから、外板内で内板がズレやすいものとなっている。このため、この支柱に棚板取付金具を付設して、棚板上に物品を載せると、棚板が傾いたり、落下したりするおそれがある。
そこで、この発明では、内板の2つの側片にダボ突起を付設し、他方外板の折り返し部分にはダボ孔を設け、ダボ突起をダボ孔に嵌入させて、内板と外板とのズレを防ぐこととした。
However, the strut proposed by Japanese Utility Model Publication No. 7-5442 is merely to fold back the outer plate portion protruding from the inner plate so that the folded portion covers the inner surface of the inner plate. And the inner plate is easily displaced in the outer plate. For this reason, if a shelf mounting bracket is attached to this support and an article is placed on the shelf, the shelf may be tilted or dropped.
Therefore, in the present invention, dowel protrusions are attached to the two side pieces of the inner plate, dowel holes are provided in the folded portion of the other outer plate, the dowel protrusions are fitted into the dowel holes, and the inner plate and the outer plate are connected. It was decided to prevent misalignment.

こうして、この発明では実開平7−5442号公報が提案するように、外板と内板とで支柱を構成することとするが、その間にダボ突起とダボ孔とを設け、それらの嵌合によって内板と外板との間のズレを防ぐとともに、支柱が天板及び底板と接続する部分では内板を無くし、外板を直接天板及び底板にボルトで締め付けてワゴンの枠体を構成することとした。このようにすると、堅固なワゴンが作れるとともに、棚板の付設及び位置変更が容易となることが確認された。この発明はこのような知見に基づいて完成されたものである。   Thus, in this invention, as proposed in Japanese Utility Model Publication No. 7-5442, the outer plate and the inner plate form a support column. However, a dowel protrusion and a dowel hole are provided between them, and by fitting them, In addition to preventing misalignment between the inner and outer plates, the inner plate is eliminated where the column connects to the top and bottom plates, and the outer plate is directly tightened to the top and bottom plates with bolts to form the wagon frame. It was decided. In this way, it was confirmed that a solid wagon could be produced and that the shelf board could be easily attached and changed in position. The present invention has been completed based on such knowledge.

この発明は、金属製の支柱、天板、底板、棚板、係止具及びキャスターからなる組立式ワゴンを提供するものであって、天板と底板と棚板は何れも同形同大の直角四辺形の浅い箱状体で構成し、そのうち棚板だけは箱状体の四隅を斜めに切り落とした構造とし、支柱は横断面L形の外板と横断面が船底形の内板とで構成し、船底形の内板は平らな中央片とこれから135度の角度をなして両側に起立する側片とからなり、中央片には係止具係止用の係止孔が穿設され、両側片にはダボ突起が付設されており、外板は内板の外面を覆って幅方向でも長手方向でも内板より食み出しており、幅方向の食み出し部はダボ孔を備えていて折り返されてダボ孔内に内板のダボ突起を嵌入させて内板と一体となっており、長手方向の食み出し部には天板と底板とに連結するためのボルト孔を備えて支柱が構成され、底板にはキャスターが固定可能とされていることを特徴とするものである。   The present invention provides an assembly-type wagon comprising a metal support, a top plate, a bottom plate, a shelf plate, a locking tool, and a caster, and the top plate, the bottom plate, and the shelf plate are all the same shape and size. It is composed of a shallow box-shaped body with a right-angled quadrilateral, of which only the shelf plate has a structure in which the four corners of the box-like body are cut off obliquely, and the column is an outer plate with an L-shaped cross section and an inner plate with a cross-sectional shape at the bottom of the ship. The bottom plate is composed of a flat central piece and side pieces standing at both sides at an angle of 135 degrees, and the central piece has a locking hole for locking the locking tool. The dowel protrusions are attached to both side pieces, and the outer plate covers the outer surface of the inner plate and protrudes from the inner plate in both the width direction and the longitudinal direction, and the protruding portion in the width direction has dowel holes. The dowel projections of the inner plate are inserted into the dowel holes and integrated with the inner plate, and the protruding portion in the longitudinal direction is Post is configured with a bolt hole for coupling to the plate, the bottom plate is characterized in that the casters and can be fixed.

一般にワゴンは嵩張るものであるところ、この発明ではワゴンを組立式としたので、不使用時には分解しておくことができ、使用時に組み立てて使用することができるので、収納に便利である。とくに、このワゴンは4本の支柱、天板、底板、棚板、係止具、及びキャスターに分解できるので、嵩を小さくすることができ、従ってとくに収納に便利である。また、天板、底板及び棚板を同形同大の浅い箱状体としたから、これらは軽量で強度が大きく、また経済的に製造することができる。   In general, the wagon is bulky. In the present invention, since the wagon is an assembly type, it can be disassembled when not in use, and can be assembled and used when in use, which is convenient for storage. In particular, this wagon can be disassembled into four struts, a top plate, a bottom plate, a shelf plate, a locking tool, and a caster, so that the bulk can be reduced, and therefore it is particularly convenient for storage. In addition, since the top plate, the bottom plate, and the shelf plate are formed into shallow boxes having the same shape and the same size, they are lightweight, have high strength, and can be manufactured economically.

また、この発明では、支柱を断面L字形の外板と、断面船底形の内板とで構成し、外板を内板から食み出させて、幅方向の食み出し部にダボ孔を設け、他方、内板の側片にダボ突起を設けたから、食み出し部を折り返して内板に重ねたとき、ダボ突起をダボ孔内に嵌入させることができ、これによって、内板が外板内でズレるのを防ぐことができる。従って、内板の係止孔に係止具を係止させて、係止具上に棚板を載せた時、棚板上に重量の大きい物品を載せても、棚板が傾いたり落下したりすることがない。   Further, in the present invention, the support column is composed of an outer plate having an L-shaped cross section and an inner plate having a cross-section ship bottom, and the outer plate is protruded from the inner plate, and the dowel hole is formed in the protruding portion in the width direction. On the other hand, since the dowel protrusion is provided on the side piece of the inner plate, the dowel protrusion can be fitted into the dowel hole when the protruding portion is folded and overlapped with the inner plate. It is possible to prevent displacement in the board. Therefore, when the locking tool is locked in the locking hole of the inner plate and the shelf board is placed on the locking tool, even if a heavy article is placed on the shelf board, the shelf board tilts or falls. There is nothing to do.

また、支柱は外板と内板との一体により構成されているため、強度が大きく、外板が内板の外面を覆っているため、外部からは外板だけが見えることとなり、従って見栄えがよい。また、支柱の上端と下端には内板を無くしたので、天板と底板とを直接ボルトで外板に連結させることができ、従って、組み立てたときワゴンの枠体を強固にすることができる。   In addition, since the strut is constructed by integrating the outer plate and the inner plate, the strength is high, and since the outer plate covers the outer surface of the inner plate, only the outer plate can be seen from the outside, and therefore the appearance is good. Good. Moreover, since the inner plate is eliminated from the upper and lower ends of the support column, the top plate and the bottom plate can be directly connected to the outer plate with bolts, and therefore the wagon frame can be strengthened when assembled. .

また、支柱の長手方向の中央部にだけ内板を設けることとし、内板の中央片に係止孔を穿設したので、係止孔に係止具を差し込むだけで棚受けを付設することができる。他方、棚板は直角四辺形の浅い箱状体の四隅を斜めに切り落とした形状にしたから、四隅に付設した棚受けの棚板を容易に且つ確実に載せることができ、また載せただけで棚板を安定な状態に維持することができる。従って、棚板の設置と、位置の変更が容易である。
この発明はこのような利点をもたらす。
Also, the inner plate is provided only at the center in the longitudinal direction of the support column, and since the locking hole is drilled in the central piece of the inner plate, the shelf holder can be attached simply by inserting the locking tool into the locking hole. Can do. On the other hand, since the shelf board is formed by obliquely cutting off the four corners of a right-angled quadrilateral shallow box-like body, the shelf board attached to the four corners can be easily and securely placed, and only by placing it The shelf board can be maintained in a stable state. Therefore, it is easy to install the shelf board and change the position.
The present invention provides such advantages.

この発明に係る組立ワゴンは、支柱、天板、底板、棚板、係止具及びキャスターの6種のもので構成される。そのうち最大の特徴を持つものは支柱であるから、まず支柱の構造から説明する。支柱は横断面がL形の外板と、横断面が船底形の内板とで構成される。   The assembly wagon according to the present invention is composed of six types of support columns, top plate, bottom plate, shelf plate, locking tool, and caster. Since the one with the greatest feature is the support, the structure of the support will be described first. The support column is composed of an outer plate having an L-shaped cross section and an inner plate having a ship-bottom cross section.

内板1は、図1に示したように、帯板を長手方向に延びる2本の折曲線に沿って折曲して、平らな中央片1aと、これから135度の角度をなして起立する2つの側片1bとで構成される。中央片1aには係止孔1cが多数一列に並び一様な間隔をおいて穿設されている。係止孔1cは後に述べる係止具を係止させるためのものである。また、中央片1aには係止孔1cに近接してビス孔1dが穿設されている。ビス孔1dは係止具が係止孔から外れるのを防ぐためのものである。   As shown in FIG. 1, the inner plate 1 is bent along two folding lines extending in the longitudinal direction of the band plate, and stands up at an angle of 135 degrees from the flat central piece 1a. It consists of two side pieces 1b. A large number of locking holes 1c are arranged in a row in the central piece 1a at regular intervals. The locking hole 1c is for locking a locking tool described later. A screw hole 1d is formed in the central piece 1a adjacent to the locking hole 1c. The screw hole 1d is for preventing the locking tool from coming off the locking hole.

また、内板1の2つの側片1bにはダボ突起1eが複数個適当な間隔を置いて突設される。2つの側片1bは、中央片1aに対して左右対称の形状となっている。従って、ダボ突起も左右対称に設けられる。複数のダボ突起のうち、長手方向の端に位置するダボ突起1eは、中央片1aの長手方向の端に位置するビス孔1dと、長手方向の端から等しい距離のところに設けられることが好ましい。なぜならば、このようにすると、内板1を外板2内に挿入し、外板2の食み出し部2cを内板に向かって折り返すとき、内板のビス孔1dが外板2のダボ孔2dと1つの直線上に並ぶようにして折り返せば、ダボ突起1eをダボ孔2d内に確実に嵌入させることができるからである。   A plurality of dowel projections 1e are provided on the two side pieces 1b of the inner plate 1 at an appropriate interval. The two side pieces 1b are symmetrical with respect to the central piece 1a. Therefore, dowel protrusions are also provided symmetrically. Of the plurality of dowel projections, the dowel projection 1e located at the longitudinal end is preferably provided at a distance equal to the screw hole 1d located at the longitudinal end of the central piece 1a from the longitudinal end. . This is because when the inner plate 1 is inserted into the outer plate 2 and the protruding portion 2c of the outer plate 2 is turned back toward the inner plate, the screw hole 1d of the inner plate is formed in the dowel of the outer plate 2. This is because the dowel protrusion 1e can be surely fitted into the dowel hole 2d if the dowel protrusion 1e is folded back in line with the hole 2d.

外板2は図2に示したように、横断面がL字状の長尺体であって、一般にアングル材と呼ばれるものである。外板2は長手方向の両端近くに天板と底板を固定するためのボルト2aと2bとを備えている。また、外板2は長手方向の両端を除く中央部分の両側に食み出し部分2cを備えている。なお、2eは取手をつけるためのボルト孔である。   As shown in FIG. 2, the outer plate 2 is a long body having an L-shaped cross section, and is generally called an angle member. The outer plate 2 includes bolts 2a and 2b for fixing the top plate and the bottom plate near both ends in the longitudinal direction. In addition, the outer plate 2 includes protruding portions 2c on both sides of the central portion excluding both ends in the longitudinal direction. Reference numeral 2e denotes a bolt hole for attaching a handle.

食み出し部分2cが存在する領域に、内板1を置き、食み出し部分2cを内側へ折り曲げて、内板の側片1b上に重ねる。このとき一般に外板2に対する内板1の位置関係を調整して、食み出し部分2cに設けたダボ孔2dが内板に設けダボ突起1eを嵌入させるようにする。こうして、図3に示したような支柱が作られる。   The inner plate 1 is placed in a region where the protruding portion 2c exists, the protruding portion 2c is bent inward, and overlapped on the side piece 1b of the inner plate. At this time, generally, the positional relationship of the inner plate 1 with respect to the outer plate 2 is adjusted so that the dowel hole 2d provided in the protruding portion 2c is provided in the inner plate and the dowel protrusion 1e is inserted. In this way, a support column as shown in FIG. 3 is formed.

この支柱では、複数個のダボ突起1eがダボ孔2d内に嵌入しているので、内板1と外板2との結合が強固である。従って、内板1が外板2内でズレることは全くなくなっている。なお、図3では係止孔1cの1つに係止具4が係止されている。   In this support column, since the plurality of dowel projections 1e are fitted into the dowel holes 2d, the coupling between the inner plate 1 and the outer plate 2 is strong. Therefore, the inner plate 1 is not displaced in the outer plate 2 at all. In FIG. 3, the locking tool 4 is locked to one of the locking holes 1c.

図3に示した係止具4は、これを拡大して示すと図4に示したような構造のものである。係止具4は、金属板の小片において、一端を表面がわに垂直に折曲して棚受部41とし、裏面がわに断面L字状の引掛部42を突設し、その際、引掛部42におけるLの折曲線44を、棚受部41の折曲線43と平行に向わせて作られている。なお、図4では引掛部42を突設するのに、金属板にコの字状の切れ目を入れて、内部を裏面がわに押し出すことによって引掛部42を作っている。   When the locking tool 4 shown in FIG. 3 is enlarged, it has a structure as shown in FIG. In the small piece of the metal plate, the locking tool 4 is bent at one end perpendicularly to the front surface to form a shelf receiving portion 41, and the rear surface protrudes from the hook portion 42 having an L-shaped cross section on the side. The folding line 44 of L in the hooking part 42 is made to face the folding line 43 of the shelf receiving part 41 in parallel. In FIG. 4, in order to project the hooking portion 42, the hooking portion 42 is made by making a U-shaped cut in the metal plate and pushing the inside back to the side.

係止具42は、図5に示したように、棚受部41を下にして引掛部42を支柱の係止孔1c内に通してのち、降下させて支柱3に取り付けられている。こうして取り付けただけでは、係止具4はこれを上昇させると支柱から外れる。そこで、これを防ぐためにビス孔45にビスを挿入し、そのビスを支柱のビス孔1dに固定して係止具4の外れるのを防ぐ。このために、支柱3のビス孔1dには雌ねじが付設されている。   As shown in FIG. 5, the locking tool 42 is attached to the column 3 by being lowered after passing the hooking portion 42 into the column locking hole 1 c with the shelf receiving portion 41 facing down. By simply attaching it in this way, the locking tool 4 is detached from the support column when it is raised. Therefore, in order to prevent this, a screw is inserted into the screw hole 45 and the screw is fixed to the screw hole 1d of the support to prevent the locking tool 4 from coming off. For this purpose, a female screw is attached to the screw hole 1 d of the support column 3.

この発明で用いられる天板と底板及び棚板は、何れも同形同大の直角四辺形の浅い箱状体で作られている。その箱状体は図6に示したようなものである。図6に示した箱状体5は、底51に高さの等しい4個の側壁52、53等を立設しただけのものである。箱状体5の四隅には支柱への固定のためのボルト孔50が付設されている。   The top plate, the bottom plate, and the shelf plate used in the present invention are all made of a shallow rectangular box having the same shape and the same right-angled quadrilateral. The box-like body is as shown in FIG. The box-shaped body 5 shown in FIG. 6 has a structure in which four side walls 52, 53 and the like having the same height are erected on the bottom 51. Bolt holes 50 are attached to the four corners of the box-like body 5 for fixing to the column.

天板と底板とに用いるには、図6に示した形状のものでもよいが、特開2006−122191号公報が教えるように、箱状体の側壁外面に補強片を付設することが好ましい。すなわち、図7に示したように、各側壁の支柱に接する部分に補強片56を付設し、補強片の端面57を支柱の側面31に密接させるとともに、補強片56の外面を支柱外面と面一にすることが好ましい。このようにすると見栄えがよいだけでなく、枠のゆがみを確実に防止できる。なお、補強片56は側壁の長手方向全体に延びていなくて、支柱の側面に近いところだけに付設されていてもよい。   Although the shape shown in FIG. 6 may be used for the top plate and the bottom plate, it is preferable to attach a reinforcing piece to the outer surface of the side wall of the box-shaped body as taught in JP-A-2006-122191. That is, as shown in FIG. 7, the reinforcing piece 56 is attached to the portion of each side wall that is in contact with the column, the end surface 57 of the reinforcing piece is brought into close contact with the side surface 31 of the column, and the outer surface of the reinforcing piece 56 faces the column outer surface. It is preferable to make it one. In this way, not only the appearance is good, but also distortion of the frame can be reliably prevented. Note that the reinforcing piece 56 does not extend in the entire longitudinal direction of the side wall, and may be provided only at a location near the side surface of the support column.

この発明では、棚板は図6及び図7に示した形状そのままで用いるのではなくて、箱状体の四隅のかどを切り落とした形状にして用いる必要がある。すなわち、かどを底51に垂直で側壁52と53とに45度の角度で交わる平面で切断し、かどを切り落として、図5に符号6で示した構造のものとして用いる必要がある。このようにすると、棚板のかどは支柱3の内板1の内面に合う形となるので、支柱3に付設された係止具4の棚受部44に容易に載せることができる。
底板の底には、四隅に自在キャスターを付設するためのボルト孔が穿設されている。底板は天板と同様にかど部がボルトで支柱の外板に固定される。
In the present invention, the shelf plate is not used as it is in the shape shown in FIGS. 6 and 7, but it is necessary to use the shelf plate by cutting off the corners of the four corners. That is, it is necessary to cut the corner at a plane perpendicular to the bottom 51 and intersect with the side walls 52 and 53 at an angle of 45 degrees, cut off the corner, and use the structure shown by reference numeral 6 in FIG. If it does in this way, since the corner of a shelf board will become the shape which fits the inner surface of the inner board 1 of the support | pillar 3, it can mount easily in the shelf receiving part 44 of the latching tool 4 attached to the support | pillar 3.
Bolt holes are provided in the bottom of the bottom plate for attaching free casters at four corners. The bottom plate is fixed to the outer plate of the column with bolts in the same manner as the top plate.

この発明に係るワゴンを組み立てるには次のようにする。支柱3としては、図3に示したように、内板1が外板2と既に一体にされたものを使用する。このような支柱3を4本用いて、図8に示したように底板7の四隅にボルト8で固定する。次いで支柱3の上端に天板9を同様にボルト8で固定する。こうしてワゴンの枠体を作る。   The wagon according to the present invention is assembled as follows. As the support 3, as shown in FIG. 3, an inner plate 1 already integrated with an outer plate 2 is used. Four such columns 3 are used and fixed with bolts 8 at the four corners of the bottom plate 7 as shown in FIG. Next, the top plate 9 is similarly fixed to the upper end of the column 3 with bolts 8. This creates a wagon frame.

次いで底板7にキャスターを付設し、支柱3の1つの係止孔1cに係止具4の引掛部42を挿入して係止具4を支柱3に係止し、さらに係止具4のビス孔45にビスを通して、係止具4を支柱3に固定する。こうして4個の係止具4が支柱3に固定されたあとで、4個の係止具4の各棚受部41上に棚板6を載せてワゴンとする。   Next, a caster is attached to the bottom plate 7, a hooking portion 42 of the locking tool 4 is inserted into one locking hole 1 c of the support column 3 to lock the locking tool 4 to the support column 3, and a screw of the locking tool 4. The locking tool 4 is fixed to the support column 3 through a screw through the hole 45. After the four locking tools 4 are fixed to the column 3 in this way, the shelf board 6 is placed on each shelf receiving portion 41 of the four locking tools 4 to form a wagon.

このワゴンの組み立ては容易である。こうして組み立てたワゴンにおいて、棚板の位置を変えるには、棚板を外し、ビスを抜いて係止具を外し、別の位置へ移動させてのちビス止めし、あとは係止具に棚板を載せるだけで足りるから、棚板の位置変更は容易である。逆に、組み立てたワゴンを分解するには、上述の組み立てと全く逆の順序で容易に行うことができる。従って、この発明に係るワゴンは、組み立ても分解も容易である。
なお、ワゴンに取手を付設する必要があるときは、支柱3に設けたボルト孔2eによって容易に取手を付設することができる。
The assembly of this wagon is easy. To change the position of the shelf board in the wagon assembled in this way, remove the shelf board, pull out the screw, remove the locking tool, move it to another position, and then fix it with the screw. Since it is sufficient to mount the rack, it is easy to change the position of the shelf board. Conversely, disassembling the assembled wagon can be easily performed in the exact reverse order of the assembly described above. Therefore, the wagon according to the present invention is easy to assemble and disassemble.
In addition, when it is necessary to attach a handle to a wagon, a handle can be easily attached by the bolt hole 2e provided in the support | pillar 3.
