Description
本発明は、台車に関するものである。 The present invention relates to a carriage.
荷物を載置し、その荷物を運搬するための台車は、荷物を載置する架台と、その下面に固定されたキャスターとから構成されている。従来より、キャスターを架台に固定して取り付ける方法としては、ボルトとナット、ねじを用いて固定する方法や、ボルトやねじを用いずに架台にキャスターを固定する方法等が用いられている。 A cart for placing a load and transporting the load is composed of a gantry on which the load is placed and a caster fixed to the lower surface thereof. Conventionally, as a method of fixing and attaching a caster to a pedestal, a method of fixing using a bolt, a nut and a screw, a method of fixing a caster to a pedestal without using a bolt or screw, and the like are used.
例えば、従来の台車61において、架台が内部にハニカム構造となった中空パネルを採用したものが知られている。この中空パネルは、中空であるゆえ、ボルトによってキャスター66を強固に固定することはできなかった。そのため、中空パネルの両側にある程度の面積を持たせた金属板65などで中空パネルをはさみこみ、ボルトの沈み込みを防いでいた。具体的には、図7に示すように、中空パネル製の架台62と、その上面63の4箇所の角部に備えられた金属板65と、架台の下面64に備えられたキャスター66のキャスター板67とを、ボルト68とナット69で締結していた。ところが、この構造であれば、架台の上面63の4箇所の角部に備えられた金属板65と金属板65が備えられていない架台の上面63とで段差が生じるとともに、両者の間に隙間ができることから、搬送する荷物が段差に引っ掛かり載置された荷物に傷がついたり荷物が台車から落下する恐れがあるほか、台車自体の見栄えもよくない。 For example, a conventional cart 61 that employs a hollow panel in which a gantry has a honeycomb structure is known. Since this hollow panel is hollow, the casters 66 could not be firmly fixed with bolts. For this reason, the hollow panel is sandwiched between metal plates 65 having a certain area on both sides of the hollow panel to prevent the bolt from sinking. Specifically, as shown in FIG. 7, a frame 62 made of a hollow panel, metal plates 65 provided at four corners of the upper surface 63, and casters of casters 66 provided on the lower surface 64 of the frame. The plate 67 was fastened with bolts 68 and nuts 69. However, with this structure, a step is generated between the metal plate 65 provided at the four corners of the upper surface 63 of the gantry and the upper surface 63 of the gantry not provided with the metal plate 65, and there is a gap between the two. As a result, there is a risk that the transported baggage will be caught by a step and the loaded baggage may be damaged or the baggage may fall from the cart, and the cart itself will not look good.
また、ボルトやねじを用いずに架台にキャスターを固定する方法(例えば、特許文献1)を用いる場合には、架台に貫通した孔を設けないため架台の上面に段差が生じないが、構造が複雑となる。 In addition, when using a method for fixing casters to a gantry without using bolts or screws (for example, Patent Document 1), there is no step on the upper surface of the gantry because there is no hole penetrating the gantry. It becomes complicated.
一方、特許文献2に示すように、金属製の部材に金属製のボルトを溶接によって接合して固定するための溶接ボルトなるものがある。 On the other hand, as shown in Patent Document 2, there is a welding bolt for joining and fixing a metal bolt to a metal member by welding.
本願発明はこのことに鑑み、中空パネルなどのボルトによる締結が困難な基体など、種々の基体にねじ部材を取り付け得るようにしたねじ部材の固定構造によって、架台にキャスターが取り付けられた台車を提供することを課題とする。 In view of this, the present invention provides a carriage in which a caster is attached to a gantry by a screw member fixing structure that allows a screw member to be attached to various bases, such as bases that are difficult to fasten with bolts such as hollow panels. The task is to do.
上記の課題を解決するため、本願発明は、荷物の載置する架台と、前記架台の下面に固定されたキャスターとを備え、前記架台を基体とし、前記架台の下面を基体側接合面とし、雄ねじ又は雌ねじを有するねじ部材によって、前記基体側接合面である前記架台の下面に前記キャスターが固定された台車を提供する。 In order to solve the above problems, the present invention comprises a gantry on which a load is placed, and a caster fixed to the lower surface of the gantry, the gantry as a base, and the lower surface of the gantry as a base-side joining surface, A cart in which the casters are fixed to the lower surface of the pedestal, which is the base-side joint surface, is provided by a screw member having a male screw or a female screw.
この台車にあっては、補助部材に前記ねじ部材が装着されており、前記補助部材は、補助側接合面と、前記補助側接合面と反対側の面である補助側表面と、前記補助側接合面と前記補助側表面とを貫通した貫通孔を備え、前記貫通孔に前記ねじ部材が配置されており、前記ねじ部材の中心軸が前記貫通孔の軸方向と実質的に同一方向に伸びるものであり、前記補助部材は、前記補助側接合面を前記基体の基体側接合面に接合されたものであり、前記補助側接合面と前記基体側接合面は、共に、合成樹脂製であり融着されることによって、前記接合がなされたものである。 In this cart, the screw member is mounted on an auxiliary member, and the auxiliary member includes an auxiliary side joining surface, an auxiliary side surface that is a surface opposite to the auxiliary side joining surface, and the auxiliary side. A through-hole penetrating the joint surface and the auxiliary-side surface, the screw member being disposed in the through-hole, and a central axis of the screw member extending in substantially the same direction as the axial direction of the through-hole The auxiliary member is formed by bonding the auxiliary side bonding surface to the substrate side bonding surface of the base body, and both the auxiliary side bonding surface and the base side bonding surface are made of a synthetic resin. The bonding is achieved by fusing.
前記の架台、即ち、前記の基体は、前記基体側接合面が合成樹脂製であれば特その構造や材質は自由であるが、中空パネルなどの、通常はねじを強固に設けることが困難なものである場合に、本願発明は特に有利に作用する。 If the base-side joining surface is made of a synthetic resin, the structure and material of the base, that is, the base, is free. However, it is usually difficult to provide a solid screw such as a hollow panel. In this case, the present invention works particularly advantageously.
より具体的には、前記ねじ部材が、軸部に雄ねじを備えたものである場合、前記軸部の一端に、前記軸部の径よりも大きな径を有する頭部を備えたものとすることが好ましく、前記補助側接合面と前記基体側接合面との少なくとも何れか一方に、前記頭部を収容するための収容空間が設けられ、前記ねじ部材が前記補助側接合面から前記貫通孔に挿入されて、前記軸部の少なくとも雄ねじの一部が前記補助側表面に突出しているものとすることができる。 More specifically, when the screw member is provided with a male screw at the shaft portion, a head portion having a diameter larger than the diameter of the shaft portion is provided at one end of the shaft portion. Preferably, an accommodation space for accommodating the head is provided in at least one of the auxiliary side joining surface and the base body side joining surface, and the screw member extends from the auxiliary side joining surface to the through hole. It is inserted, and at least a part of the male screw of the shaft portion may protrude from the auxiliary side surface.
前記ねじ部材は、雌ねじを有するナットとして実施することもできる。この場合、前記補助側接合面と前記基体側接合面との少なくとも何れか一方に、前記ナットを収容するための収容空間が設けられる。このナットは、前記補助側接合面と前記基体側接合面とが融着又は接着されることによって、両者間に挟まれた状態となる。このナットに対して、螺合するボルトが、前記貫通孔から挿入され、ナットに螺合される。 The screw member may be implemented as a nut having an internal thread. In this case, an accommodation space for accommodating the nut is provided in at least one of the auxiliary side joining surface and the base body side joining surface. The nut is sandwiched between the auxiliary side joining surface and the base side joining surface by fusing or bonding. A bolt to be screwed into the nut is inserted from the through hole and screwed into the nut.
さらに、前記ねじ部材は、前記補助側接合面と面一若しくは前記補助側接合面から前記基体側に突出していないこととすることによって、融着のための基体側での加工が不要となる。 Further, since the screw member is flush with the auxiliary side joining surface or does not protrude to the base side from the auxiliary side joining surface, processing on the base side for fusion is not necessary.
本願の発明では、架台が上記の基体からなり、上記のねじ部材の固定構造によって、架台にキャスターが取り付けられた台車を形成することにより、キャスターの取付構造が単純で、部品点数も少ないものを提供することができたものである。 In the invention of the present application, the gantry is composed of the above-mentioned base, and the above-described screw member fixing structure forms a cart with casters attached to the gantry, so that the caster mounting structure is simple and the number of parts is small. It was possible to provide.
本願発明は、架台の上面の形状は特に限定されるものではないが、架台の上面に段差がないものとして実施することもでき、見栄えの良い台車を提供することができる。 In the present invention, the shape of the top surface of the gantry is not particularly limited, but the top surface of the gantry can be implemented without any step, and a good-looking trolley can be provided.
以下、図面に基づき本願発明の実施の形態の一例をとりあげて説明する。なお、本願の各請求項及び明細書の記載における上下前後左右の表現は、相対的な位置関係を示すに止まり、絶対的な位置を特定するものではない。
本願発明に係るねじ部材の固定構造10は、図1に示すように、ねじ部材11と、基体21と、補助部材31とから構成される。
Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. It should be noted that the expressions of the top, bottom, front, rear, left and right in the claims and the description of the present application only indicate a relative positional relationship and do not specify an absolute position.

ねじ部材11は、その軸部12に雄ねじ13を有するものであれば、特に限定されない。市販のねじ部材を用いることができる。一例としては、六角ボルトや六角穴付きボルト、皿キャップボルト、スタッドボルト等が挙げられる。その軸部12の一端に頭部14を備える場合には、頭部14はその軸部12の径よりも大きな径を有するものとする。また、ねじ部材11の軸部12の全てが雄ねじ13を有していてもよいし、軸部12の一端から他端に向けてその一部に雄ねじ13を有していてもよく、ねじ部材11の軸部12の一端及び他端からその軸部12の中央に向けてその一部に雄ねじ13を有するものであってもよい。本実施形態においては、ねじ部材11として、皿型の頭部14を有する皿キャップボルトを用いる。皿キャップボルトの頭部14は、軸部12の一端に設けられ、その軸部12の径よりも大きな径を有し、軸部12の他端から軸部12の一端に向けてその全てに雄ねじを有する。 If the screw member 11 has the external thread 13 in the axial part 12, it will not be specifically limited. A commercially available screw member can be used. Examples include hexagon bolts, hexagon socket head cap screws, countersunk cap bolts, stud bolts, and the like. When the head portion 14 is provided with one end of the shaft portion 12, the head portion 14 has a diameter larger than the diameter of the shaft portion 12. Further, all of the shaft portion 12 of the screw member 11 may have the male screw 13, or may have the male screw 13 in a part from one end of the shaft portion 12 to the other end. 11 may have a male screw 13 at a part thereof from one end and the other end of the shaft portion 12 toward the center of the shaft portion 12. In this embodiment, a countersunk cap bolt having a countersunk head 14 is used as the screw member 11. The head portion 14 of the countersunk cap bolt is provided at one end of the shaft portion 12, has a diameter larger than the diameter of the shaft portion 12, and extends from the other end of the shaft portion 12 toward one end of the shaft portion 12. Has a male thread.
基体21は、本実施形態においては、板状部材から形成され、より詳しくは、板状部材の上面22と下面とを構成する合成樹脂製の2枚の矩形の薄板部材24の間に合成樹脂製のハニカム構造の芯材25を挟んだハニカム構造板を用いており、上記2枚の薄板部材のうちの一方が基体側接合面23となる。本実施形態においては、基体21の下面が基体側接合面23となっている。 In the present embodiment, the base 21 is formed of a plate-like member, and more specifically, a synthetic resin between two rectangular thin plate members 24 made of synthetic resin that constitute the upper surface 22 and the lower surface of the plate-like member. A honeycomb structure plate sandwiching a core material 25 having a honeycomb structure is used, and one of the two thin plate members serves as the substrate-side bonding surface 23. In the present embodiment, the lower surface of the substrate 21 is the substrate-side bonding surface 23.
基体21は、本実施形態のように、芯材25を有する板状部材に限らず、例えば、合成樹脂製の単層構造のものや、上面又は下面のうちの少なくとも何れか一方が合成樹脂製の層を有する2層以上の積層構造のものなどであってもよい。また、基体21は、板状部材に限らず、箱状やブロック状のものであってもよく、その形状は問わない。基体21の形状は、本願に係るねじ部材の固定構造10の用途に応じて適宜設定すればよい。後述する補助部材31と融着して接合させるためには、少なくとも基体21の一面に合成樹脂製の基体側接合面23を設ければよく、基体側接合面23以外の材質については、特に限定されない。基体21の複数の面に合成樹脂製の基体側接合面を設けてもよい。さらに、融着強度を増すために、基体側接合面23に凹凸を設けてもよい。本実施形態のように、基体21を、上記ハニカム構造板とした場合、ハニカム構造板は軽量でありながら強度を備えることができるという長所がある反面、ハニカム構造に対しては、ねじを強固に螺合させことが困難であるという短所があったが、本願発明に係る構造を用いることによって、強固にねじを固定させることができるという効果が発揮される。 The base body 21 is not limited to the plate-like member having the core member 25 as in the present embodiment. For example, the base member 21 has a single-layer structure made of synthetic resin, or at least one of the upper surface and the lower surface is made of synthetic resin. It may be a laminate structure of two or more layers having these layers. Moreover, the base | substrate 21 may be not only a plate-shaped member but a box shape or a block shape, and the shape is not ask | required. The shape of the base 21 may be appropriately set according to the use of the screw member fixing structure 10 according to the present application. In order to be fused and bonded to an auxiliary member 31 described later, it is only necessary to provide a base-side bonding surface 23 made of synthetic resin on at least one surface of the base 21. Materials other than the base-side bonding surface 23 are particularly limited. Not. A plurality of surfaces of the substrate 21 may be provided with a substrate-side bonding surface made of synthetic resin. Further, in order to increase the fusion strength, the substrate-side bonding surface 23 may be provided with unevenness. As in the present embodiment, when the substrate 21 is made of the above-described honeycomb structure plate, the honeycomb structure plate has an advantage that it can be provided with strength while being lightweight. Although there is a disadvantage that it is difficult to screw together, the use of the structure according to the present invention provides an effect that the screw can be firmly fixed.
補助部材31は、本実施形態においては、合成樹脂製の矩形の板状部材を用いており、その上面を補助側接合面32とし、補助側接合面32と反対側の面、つまりその上面と対向する下面を補助側表面33としている。補助部材31は、本実施形態のように、単層構造のものに限らず、例えば、上面又は下面のうちの少なくとも何れか一方が合成樹脂製の層を有する2層以上の積層構造のものや、芯材を有するものなどであってもよい。また、補助部材31は、板状部材に限らず、箱状やブロック状のものであってもよく、その形状は問わない。補助部材31の形状は、本願に係るねじ部材の固定構造10の用途に応じて適宜設定すればよい。上述の基体21と融着して接合させるために、少なくとも補助部材31の一面に合成樹脂製の補助側接合面32と、その補助側接合面32と対向する面に補助側表面33とを設ければよく、また、補助側接合面32以外の材質については特に限定されない。さらに、融着強度を増すために、補助側接合面32に凹凸を設けてもよい。融着による接合の場合には、前述の溶融性のある基体側接合面23と補助側接合面32との少なくとも何れか一方が溶融性のある素材によって構成されるが、接着剤による接着の場合には、このような制限がなく、素材の自由度が増す。 In the present embodiment, the auxiliary member 31 is a rectangular plate-shaped member made of synthetic resin, the upper surface of which is the auxiliary side bonding surface 32, and the surface opposite to the auxiliary side bonding surface 32, that is, the upper surface thereof. The opposing lower surface is an auxiliary side surface 33. The auxiliary member 31 is not limited to a single-layer structure as in the present embodiment, and for example, has a laminated structure of two or more layers in which at least one of the upper surface and the lower surface has a synthetic resin layer. It may be one having a core material. The auxiliary member 31 is not limited to a plate-like member, and may be a box shape or a block shape, and the shape thereof is not limited. What is necessary is just to set the shape of the auxiliary member 31 suitably according to the use of the fixing structure 10 of the screw member which concerns on this application. In order to fuse and bond to the base body 21, at least one auxiliary member 31 is provided with a synthetic resin auxiliary side bonding surface 32, and an auxiliary side surface 33 is provided on the surface facing the auxiliary side bonding surface 32. The material other than the auxiliary side joining surface 32 is not particularly limited. Further, in order to increase the fusion strength, the auxiliary side joining surface 32 may be provided with irregularities. In the case of bonding by fusion, at least one of the aforementioned meltable substrate side bonding surface 23 and auxiliary side bonding surface 32 is made of a meltable material. There is no such restriction, and the degree of freedom of material increases.
ねじ部材11は、補助部材31に装着されている。本実施形態においては、補助部材31の4箇所の角部付近に、補助側接合面32と補助側表面33とを貫通した4つの貫通孔34を備え、これらの貫通孔34は、ネジ部材11の頭部14を収容するための収容空間35と、ねじ部材11の軸部12を挿入するための挿入穴36とから構成され、これらの挿入穴36にねじ部材11を挿入することによって、ねじ部材11は補助部材31に装着されている。補助部材31に備える貫通孔34の位置や数も、特に限定されない。 The screw member 11 is attached to the auxiliary member 31. In the present embodiment, four through holes 34 penetrating the auxiliary side joining surface 32 and the auxiliary side surface 33 are provided in the vicinity of the four corners of the auxiliary member 31, and these through holes 34 are formed in the screw member 11. A housing space 35 for housing the head portion 14 of the screw member 11 and an insertion hole 36 for inserting the shaft portion 12 of the screw member 11. By inserting the screw member 11 into these insertion holes 36, the screw The member 11 is attached to the auxiliary member 31. The position and number of the through holes 34 provided in the auxiliary member 31 are not particularly limited.
収容空間35は、補助部材31の補助側接合面32から補助側表面33に向かって形成され、その深さは、ねじ部材11の頭部14が収容できれば特に限定されない。上記の貫通孔34において、収容空間35以外の部分が軸部の挿入穴36となる。よって、収容空間35を備える面が補助側接合面32となり、挿入穴36を備える面が補助側表面33となる。そして、ねじ部材11の軸部12の少なくとも雄ねじ13の一部が、補助部材31の補助側表面33から突出するよう、ねじ部材11を補助部材31に装着する。 The accommodation space 35 is formed from the auxiliary side joining surface 32 of the auxiliary member 31 toward the auxiliary side surface 33, and the depth thereof is not particularly limited as long as the head portion 14 of the screw member 11 can be accommodated. In the above-described through hole 34, a portion other than the accommodation space 35 becomes an insertion hole 36 of the shaft portion. Therefore, the surface provided with the accommodation space 35 becomes the auxiliary side joining surface 32, and the surface provided with the insertion hole 36 becomes the auxiliary side surface 33. Then, the screw member 11 is attached to the auxiliary member 31 so that at least a part of the male screw 13 of the shaft portion 12 of the screw member 11 protrudes from the auxiliary side surface 33 of the auxiliary member 31.
この実施の形態にあっては、軸部挿入孔36には、雌ねじが形成されておらず、軸部12に設けられた雄ねじ13とは螺合しないものであり、軸部挿入孔36の径は雄ねじの外径と略等しいかそれよりも大きい。 In this embodiment, the shaft portion insertion hole 36 is not formed with a female screw and does not screw with the male screw 13 provided in the shaft portion 12. Is approximately equal to or greater than the outer diameter of the male thread.
上述のように、補助部材31に収容空間35を設け、ネジ部材11の頭部14を収容することによって、ねじ部材11は、補助側接合面32と面一若しくは補助側接合面32から基体21側に突出しないことから、融着又は接着のための基体21側での加工が不要となる。 As described above, by providing the auxiliary member 31 with the accommodating space 35 and accommodating the head portion 14 of the screw member 11, the screw member 11 is flush with the auxiliary-side joining surface 32 or from the auxiliary-side joining surface 32. Since it does not protrude to the side, processing on the base 21 side for fusing or bonding becomes unnecessary.
本実施形態においては、補助部材31に軸部12の雄ねじ13に螺合しない無ねじの貫通孔34を備えたが、このような貫通孔34を備えることなく、ねじ部材11を補助部材31に装着してもよい。例えば、図示はしないが、貫通孔34と軸部12とを螺合させてもよい。具体的には、貫通孔34に雌ねじを形成しておき、これに軸部12を螺合させてもよく、或いは、ねじ部材11にタッピングネジなどのねじ加工機能のあるものを用いて、貫通孔34には当初は雌ねじを形成せずに、ねじ部材11によって、雌ねじを形成するようにしてもよい。さらに、ねじ部材11にドリリング・アンド・タッピングネジなどのドリル機能とねじ加工機能とを備えたものを用いて、貫通孔34自体をねじ部材11によって形成するようにしてもよい。また、貫通孔34を、雌ねじを形成した部分と無ねじ部分との双方から構成してもよい。貫通孔34には、必ずしも収容空間35を設ける必要はない。 In the present embodiment, the auxiliary member 31 is provided with the screwless through hole 34 that is not screwed into the male screw 13 of the shaft portion 12, but the screw member 11 is attached to the auxiliary member 31 without such a through hole 34. You may wear it. For example, although not shown, the through hole 34 and the shaft portion 12 may be screwed together. Specifically, a female screw may be formed in the through hole 34, and the shaft portion 12 may be screwed into the through hole 34. Alternatively, a screw member 11 having a threading function such as a tapping screw may be used for penetration. The hole 34 may be formed with the screw member 11 without initially forming a female thread in the hole 34. Further, the through hole 34 itself may be formed by the screw member 11 using a screw member 11 having a drill function and a screw machining function such as a drilling and tapping screw. Moreover, you may comprise the through-hole 34 from both the part in which the internal thread was formed, and a non-screw part. It is not always necessary to provide the accommodation space 35 in the through hole 34.
いずれにせよ、装着されたねじ部材11の軸部12の少なくとも雄ねじ13の一部が、補助部材31の補助側表面33から突出するよう、ねじ部材11を補助部材31に装着する。 In any case, the screw member 11 is attached to the auxiliary member 31 so that at least a part of the male screw 13 of the shaft portion 12 of the attached screw member 11 protrudes from the auxiliary side surface 33 of the auxiliary member 31.
本実施形態においては、収容空間35を補助部材31に備えたが、収容空間35は、基体21もしくは補助部材31の少なくとも何れか一方に備えればよく、両者に備えてもよい。また、頭部の有しないねじ部材11を本願発明に係るねじ部材の固定構造10に用いる場合等には、基体21にも補助部材31にも収容空間35を備えなくてもよい。基体21に収容空間を備える場合は、収容空間は、基体21の基体側接合面23からその対向面に向かって形成されるものとして実施することができる。 In the present embodiment, the accommodation space 35 is provided in the auxiliary member 31, but the accommodation space 35 may be provided in at least one of the base body 21 and the auxiliary member 31, and may be provided in both. Further, when the screw member 11 having no head is used for the screw member fixing structure 10 according to the present invention, neither the base body 21 nor the auxiliary member 31 need be provided with the accommodating space 35. When the base 21 is provided with a storage space, the storage space can be implemented as being formed from the base-side joining surface 23 of the base 21 toward the facing surface.
