The casters 31 are each attached to the truck body 20 via attachment plates.

手押部材４０は、運搬台車１を走行させるときに使用者が手で押すための部材である。手押部材４０は、長さが１０００ｍｍ前後の長尺状である。手押部材４０は下端をコーナ部材２２の挿入孔２３に挿入することで、台車本体部２０に取り付けられる。本実施形態の運搬台車１は４つの手押部材４０を有し、各コーナ部材２２の挿入孔２３に挿入される。４つの手押部材４０は、何れも同一の構成である。だだし、４つの手押部材４０を取り付ける場合に限られず、１つ、２つまたは３つの手押部材４０を取り付けてもよい。 The hand pushing member 40 is a member that is pushed by the user's hand when moving the transport trolley 1. The hand pushing member 40 has an elongated shape with a length of about 1000 mm. The hand push member 40 is attached to the truck body 20 by inserting its lower end into the insertion hole 23 of the corner member 22. The transportation cart 1 of this embodiment has four push members 40, which are inserted into the insertion holes 23 of each corner member 22. All four hand-push members 40 have the same configuration. However, the present invention is not limited to the case where four hand press members 40 are attached, and one, two or three hand press members 40 may be attached.

手押部材４０は、本体部としての本体部材４１と、保護部材４２とを有する。
本体部材４１は、長尺状かつパイプ状の部材である。本体部材４１は、例えば単管（単管パイプ）を適用することができる。単管は、ＪＩＳ Ｇ ３４４４に規定されている一般構造用炭素鋼鋼管をいい、外径が４８．６ｍｍの円管である。ただし、本体部材４１は、上述した寸法の単管に限定されるものではなく、各種の棒状や管状の部材が適用できる。 The hand-pushing member 40 has a main body member 41 as a main body portion and a protection member 42 .
The main body member 41 is an elongated and pipe-shaped member. For the main body member 41, for example, a single pipe (single pipe) can be applied. A single tube refers to a general structural carbon steel tube specified in JIS G 3444, and is a circular tube with an outer diameter of 48.6 mm. However, the main body member 41 is not limited to a single tube having the dimensions described above, and various rod-shaped or tubular members can be used.

保護部材４２は、使用者の手を保護する。保護部材４２は、本体部材４１の上端部に着脱可能に装着される。使用者（建設作業者等）は、本体部材４１に装着された保護部材４２を掴んで運搬台車１を移動させることができる。 The protective member 42 protects the user's hands.

図２と図３に示すように、保護部材４２は、グリップ部４３と、第１の保護部４４と、第２の保護部４５とを有しており、これらが一体に形成されている。また、保護部材４２には、内部に本体部材４１の上端部を挿入可能で下側（上下方向において第１の保護部４４とは反対側）に開口する取付穴４６が形成されている。保護部材４２は、例えばポリエチレン等の樹脂材料からなり、射出成形によって一体に形成される。 FIG. 2 is an external perspective view schematically showing a configuration example of the protection member 42, in which (a) is a view seen diagonally from above, and (b) is a view seen diagonally from below. FIG. 3 is a cross-sectional view schematically showing a configuration example of the protection member 42. As shown in FIG.
As shown in FIGS. 2 and 3, the protection member 42 includes a grip portion 43, a first protection portion 44, and a second protection portion 45, which are integrally formed. Further, the protection member 42 is formed with a mounting hole 46 that opens on the lower side (the side opposite to the first protection part 44 in the vertical direction) into which the upper end portion of the main body member 41 can be inserted. The protection member 42 is made of a resin material such as polyethylene, and is integrally formed by injection molding.

グリップ部４３は、略円筒状であり、使用者が片手で掴むことができる（握ることができる）寸法を有する。使用者が片手で掴めるように、例えば、長さ（上下方向寸法）は１００～２００ｍｍの範囲が好適であり、更には１２０～１８０ｍｍの範囲が好適である。また、本体部材４１に単管を用いる場合には、例えば、外径は５０～６０ｍｍの範囲が好適である。ただし、具体的な寸法は特に限定されるものではない。また、グリップ部４３の表面には、滑り止めのための凹凸パターンが設けられていてもよい。 The grip portion 43 has a substantially cylindrical shape and has dimensions that allow the user to grasp (grasp) it with one hand. For example, the length (vertical dimension) is preferably in the range of 100 to 200 mm, more preferably in the range of 120 to 180 mm, so that the user can grasp it with one hand. Further, when a single tube is used for the main body member 41, the outer diameter is preferably in the range of 50 to 60 mm, for example. However, the specific dimensions are not particularly limited. Further, the surface of the grip portion 43 may be provided with an uneven pattern to prevent slipping.

第１の保護部４４および第２の保護部４５は、グリップ部４３に近接して設けられている。具体的には、第１の保護部４４はグリップ部４３の上下方向（本体部材４１の軸線方向）の一方の端部（上側）に設けられ、第２の保護部４５はグリップ部４３の上下方向の他方の端部（下側）に設けられる。
第１の保護部４４および第２の保護部４５は、何れもグリップ部４３の外周面よりも外側に突出しており、グリップ部４３よりも大きい外径を有する。特に、第１の保護部４４および第２の保護部４５の外径は、平面視において、グリップ部４３を掴んでいる使用者の手Ｈ（指）が第１の保護部４４と第２の保護部４５に重畳してはみ出さない（平面視において外形線の内側に収まる）寸法に設定される。具体的には例えば、第１の保護部４４および第２の保護部４５の外径は、１００～１４０ｍｍの範囲が好適であり、更には１１０～１３０ｍｍの範囲が好適である。ただし、具体的な寸法は特に限定されるものではない。 The first protection part 44 and the second protection part 45 are provided close to the grip part 43. Specifically, the first protection part 44 is provided at one end (upper side) of the grip part 43 in the vertical direction (the axial direction of the main body member 41), and the second protection part 45 is provided at the top and bottom of the grip part 43. provided at the other end (lower side) of the direction.
The first protection part 44 and the second protection part 45 both protrude outward from the outer peripheral surface of the grip part 43 and have a larger outer diameter than the grip part 43. In particular, the outer diameters of the first protection part 44 and the second protection part 45 are such that, in plan view, the hand H (finger) of the user grasping the grip part 43 is The dimensions are set such that it does not overlap and protrude from the protection part 45 (it fits inside the outline in plan view). Specifically, for example, the outer diameters of the first protection part 44 and the second protection part 45 are preferably in the range of 100 to 140 mm, and more preferably in the range of 110 to 130 mm. However, the specific dimensions are not particularly limited.

第１の保護部４４は、平面視において略円形で、上側（グリップ部４３とは反対側）に向かうにしたがって外径が小さくなる先細り形状を有する。そして、第１の保護部４４の側面４７（半径方向外側の面）は、側面視において、半径方向外側かつ斜め上側に向かって膨出する曲面に形成されている。第１の保護部４４の上面４８（グリップ部４３とは反対側の面）は、上側に向かって膨出するドーム状の曲面に形成されている。第１の保護部４４の側面４７と上面４８とは、曲面によって滑らかにつながっている。なお、第１の保護部４４の下面４９は平面でよい。但し、第１の保護部４４の側面４７と下面４９とは、曲面によって滑らかにつながっている構成であることが好ましい。このように、側面視において、第１の保護部４４の側面４７および上面４８の輪郭線は曲線で形成される。
ただし、第１の保護部４４の形状は、上述した形状に限定されない。例えば、第１の保護部４４の形状は、円板状であってもよく、上側に向かって膨出する略半球形状であってもよい。 The first protection part 44 has a substantially circular shape in a plan view, and has a tapered shape in which the outer diameter becomes smaller toward the upper side (the side opposite to the grip part 43). The side surface 47 (radially outer surface) of the first protection part 44 is formed into a curved surface that bulges radially outward and obliquely upward in side view. The upper surface 48 (the surface opposite to the grip section 43) of the first protection section 44 is formed into a dome-shaped curved surface that bulges upward. The side surface 47 and the top surface 48 of the first protection part 44 are smoothly connected by a curved surface. Note that the lower surface 49 of the first protection part 44 may be a flat surface. However, it is preferable that the side surface 47 and the lower surface 49 of the first protection part 44 are smoothly connected by a curved surface. Thus, in side view, the contour lines of the side surface 47 and the top surface 48 of the first protection part 44 are formed in curved lines.
However, the shape of the first protection part 44 is not limited to the shape described above. For example, the shape of the first protection part 44 may be a disk shape, or may be a substantially hemispherical shape that bulges upward.

第２の保護部４５は、第１の保護部４４を上下方向に反転させた形状である。ただし、第２の保護部４５の形状は、上述した形状に限定されない。例えば、第２の保護部４５の形状は、円板状であってもよく、下側に向かって膨出する略半球形状であってもよい。
取付穴４６は、本体部材４１を挿入可能な穴（凹部）であり、下側（第２の保護部４５の側）が開口する。取付穴４６の内径は、本体部材４１の外径に応じて設定される。例えば、本体部材４１を取付穴４６に挿入したときに、保護部材４２が本体部材４１に対して容易に離脱しないような寸法に設定される。また、取付穴４６の深さは特に限定されないが、少なくとも使用時に横方向に力を掛けた場合に外れないような深さに設定される。 The second protection part 45 has a shape obtained by inverting the first protection part 44 in the vertical direction. However, the shape of the second protection part 45 is not limited to the shape described above. For example, the shape of the second protection part 45 may be a disk shape, or may be a substantially hemispherical shape that bulges downward.
The attachment hole 46 is a hole (recess) into which the main body member 41 can be inserted, and is open on the lower side (the side of the second protection part 45). The inner diameter of the attachment hole 46 is set according to the outer diameter of the main body member 41. For example, when the main body member 41 is inserted into the mounting hole 46, the protective member 42 is dimensioned so that it does not easily separate from the main body member 41. Further, the depth of the mounting hole 46 is not particularly limited, but is set to a depth that will not come off at least when a force is applied in the lateral direction during use.

したがって、取付穴４６に本体部材４１の上端部を挿入することにより、保護部材４２を本体部材４１に装着することができる（図１参照）。使用者は、保護部材４２を本体部材４１に装着した手押部材４０を、各コーナ部材２２の挿入孔２３に挿入することで、手押部材４０を台車本体部２０に取り付けることができ、使用者は手で手押部材４０のグリップ部４３を掴んで運搬台車１を移動させることができる。 Therefore, the protective member 42 can be attached to the main body member 41 by inserting the upper end portion of the main body member 41 into the attachment hole 46 (see FIG. 1). The user can attach the hand push member 40 to the trolley main body 20 by inserting the hand push member 40 with the protection member 42 attached to the main body member 41 into the insertion hole 23 of each corner member 22, and then use the hand push member 40. A person can move the transport cart 1 by grasping the grip portion 43 of the hand-pushing member 40 with his/her hand.

ここで、第１の実施形態に係る手押部材４０の効果について、図４と図５を参照して説明する。図４と図５は、手押部材４０の効果を説明する図である。具体的には、図４は、運搬台車１の移動中において、手押部材４０の上端部が壁等の物体Ｗに接近した状態を模式的に示す図である。図５は、運搬台車１の運搬物Ｂである板材が手押部材４０の上端部に寄り掛かった状態を模式的に示す図である。 Here, the effects of the hand press member 40 according to the first embodiment will be explained with reference to FIGS. 4 and 5. 4 and 5 are diagrams illustrating the effects of the hand-pushing member 40. Specifically, FIG. 4 is a diagram schematically showing a state in which the upper end of the hand-pushing member 40 approaches an object W such as a wall while the transport vehicle 1 is moving. FIG. 5 is a diagram schematically showing a state in which the plate material, which is the object B of the transport vehicle 1, is leaning against the upper end of the hand-pushing member 40.

図４に示すように、運搬台車１の移動中において、手押部材４０の上端部が壁等の物体Ｗに接近することがある。この際、本体部材４１の上端部に保護部材４２が装着されておらず、使用者が単に本体部材４１の上端部を直接的に掴んでいると、使用者の手Ｈ（指や手の甲）が物体Ｗに接触したり、本体部材４１と物体Ｗとに挟まれたりすることがある。これに対して、図４に示すように、本体部材４１の上端部に保護部材４２を装着し、保護部材４２のグリップ部４３を掴んでいると（握っていると）、手押部材４０の上端部が物体Ｗに接近した際に、第１の保護部４４や第２の保護部４５が物体Ｗに接触するため、グリップ部４３を掴んでいる使用者の手Ｈが物体Ｗに接触することが防止または抑制される。 As shown in FIG. 4, while the transport cart 1 is moving, the upper end of the hand-pushing member 40 may approach an object W such as a wall. At this time, if the protection member 42 is not attached to the upper end of the main body member 41 and the user simply grasps the upper end of the main body member 41 directly, the user's hand H (fingers and back of the hand) may It may come into contact with the object W or be sandwiched between the main body member 41 and the object W. On the other hand, as shown in FIG. When the upper end approaches the object W, the first protection part 44 and the second protection part 45 come into contact with the object W, so the user's hand H holding the grip part 43 comes into contact with the object W. is prevented or suppressed.

図５に示すように、板状の資材を運搬台車１で運搬する際には、板状の資材を手押部材４０の上端部に寄り掛けておくことがある。この際、運搬物Ｂである板状の資材を保護部材４２の第１の保護部４４に寄り掛けることによって、使用者が手押部材４０を掴むスペースを確保でき、かつ、使用者の手Ｈ（特に指）が運搬物Ｂに接触することを防止または抑制できる。ここで、第１の保護部４４の側面４７は斜め上側に向かって膨出する曲面であり、上面４８は上側に向かって膨出する曲面であり、側面４７と上面４８とは曲面によって滑らかにつながっている。このため、第１の保護部４４の斜め上方に運搬物Ｂが寄り掛かった場合には、曲面で運搬物Ｂを受けることになる。したがって、運搬物Ｂに接触痕が形成されることが防止または抑制される。 As shown in FIG. 5, when a plate-shaped material is transported by the transport cart 1, the plate-shaped material may be placed against the upper end of the hand-pushing member 40. At this time, by leaning the plate-shaped material that is the transported object B against the first protection part 44 of the protection member 42, a space for the user to grasp the hand-pushing member 40 can be secured, and the user's hand H (Especially fingers) can be prevented or suppressed from coming into contact with the transported object B. Here, the side surface 47 of the first protection part 44 is a curved surface that bulges diagonally upward, and the top surface 48 is a curved surface that bulges upward. linked. Therefore, when the object B leans diagonally above the first protection part 44, the object B will be received by the curved surface. Therefore, formation of contact marks on the transported object B is prevented or suppressed.

なお、運搬台車１の運搬物Ｂが運搬の際に移動して、手押部材４０の上端部に接近することがある。この場合にも、移動した運搬物Ｂが第１の保護部４４や第２の保護部４５に接触することにより、グリップ部４３を掴んでいる使用者の手Ｈに運搬物Ｂが接触することが防止または抑制される。この際、第１の保護部４４および第２の保護部４５には、半径方向外側に向かって尖った部分が設けられないから、第１の保護部４４や第２の保護部４５に接触した運搬物Ｂに接触痕が形成されることが防止または抑制される。 Note that the transported object B of the transport trolley 1 may move during transportation and approach the upper end of the hand-pushing member 40 . Also in this case, the transported object B comes into contact with the hand H of the user who is gripping the grip section 43 due to the moved object B coming into contact with the first protection part 44 and the second protection part 45. is prevented or suppressed. At this time, since the first protection part 44 and the second protection part 45 are not provided with a pointed part toward the outside in the radial direction, the first protection part 44 and the second protection part 45 are not provided with a pointed part. Formation of contact marks on the transported object B is prevented or suppressed.

このように、第１の実施形態に係る手押部材４０によれば、運搬台車１の手押部材４０を掴んでいる使用者の手Ｈに、運搬台車１の周辺の物体Ｗや運搬台車１の運搬物Ｂが接触することが防止または抑制される。更に、運搬物Ｂが保護部材４２に接触した場合であっても、運搬物Ｂに接触痕が形成されることが防止または抑制される。 As described above, according to the hand push member 40 according to the first embodiment, the hand H of the user who is grasping the hand push member 40 of the transport trolley 1 can be used to hold the object W around the transport trolley 1 or the hand push member 40 of the transport trolley 1. The conveyed object B is prevented or suppressed from coming into contact with it. Furthermore, even if the transported object B comes into contact with the protection member 42, contact marks are prevented or suppressed from being formed on the transported object B.

＜第２の実施形態＞
次に、第２の実施形態に係る手押部材の構成について図６を参照して説明する。
図６は、第２の実施形態に係る手押部材のうち保護部材５２の構成例を模式的に示す図であり、（ａ）は上側から見た図、（ｂ）は下側から見た図である。なお、第１の実施形態と同様の構成は同一符号を付して、その説明を省略する。 <Second embodiment>
Next, the configuration of the hand-pushing member according to the second embodiment will be described with reference to FIG. 6.
FIG. 6 is a diagram schematically showing a configuration example of the protection member 52 of the hand-held member according to the second embodiment, in which (a) is a view seen from above, and (b) is a view from below. It is a diagram. Note that the same configurations as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted.

図６に示すように、保護部材５２は、挿入部５３と、保護部５４とを有しており、これらが一体に形成されている。保護部材５２は、例えばポリエチレン等の樹脂材料からなり、射出成形によって一体に形成される。 As shown in FIG. 6, the protection member 52 has an insertion portion 53 and a protection portion 54, which are integrally formed. The protection member 52 is made of a resin material such as polyethylene, and is integrally formed by injection molding.

挿入部５３は、円筒状や円柱状の構成を有する部分であり、本体部材４１の上端部の内部に挿入される部分である。挿入部５３の外径は、適用対象である本体部材４１の内径に応じて設定される。例えば、挿入部５３を本体部材４１に挿入したときに、保護部材５２が本体部材４１に対して容易に離脱しないような寸法に設定される。 The insertion portion 53 is a portion having a cylindrical or columnar configuration, and is a portion inserted into the upper end portion of the main body member 41. The outer diameter of the insertion portion 53 is set according to the inner diameter of the main body member 41 to which it is applied. For example, the dimensions are set such that the protection member 52 does not easily separate from the main body member 41 when the insertion portion 53 is inserted into the main body member 41 .

保護部５４は、挿入部５３の上側に設けられる部分である。保護部５４は、適用対象である本体部材４１の外周面よりも外側に突出している。保護部５４は、例えば平面視で略円形である。保護部５４の外径は、平面視において、本体部材４１の上端部を掴んでいる使用者の指が、保護部５４からはみ出さない（平面視において保護部５４の外形線の内側に収まる）寸法に設定される。具体的には、保護部５４の外径は、１００～１４０ｍｍの範囲が好適であり、更には１１０～１３０ｍｍの範囲が好適である。ただし、具体的な寸法は特に限定されるものではない。 The protection part 54 is a part provided above the insertion part 53. The protection portion 54 protrudes outward from the outer peripheral surface of the main body member 41 to which it is applied. The protection portion 54 is, for example, approximately circular in plan view. The outer diameter of the protective part 54 is such that the user's fingers grasping the upper end of the main body member 41 do not protrude from the protective part 54 when viewed from above (the outer diameter falls within the outline of the protective part 54 when viewed from above). Set to dimensions. Specifically, the outer diameter of the protective portion 54 is preferably in the range of 100 to 140 mm, more preferably in the range of 110 to 130 mm. However, the specific dimensions are not particularly limited.

保護部５４は、第１の実施形態に係る保護部材４２の第１の保護部４４と同じ形状が適用できる。すなわち、保護部５４は、上側（挿入部５３とは反対側）に向かうにしたがって外径が小さくなる先細り形状を有する。そして、保護部５４の側面５７は、側面視において、半径方向外側でかつ斜め上側に向かって膨出する曲面に形成されている。保護部５４の上面５８（挿入部５３とは反対側の面）は、上側に向かって膨出するドーム状の曲面に形成されている。保護部５４の側面５７と上面５８とは、曲面によって滑らかにつながっている。このように、側面視において、保護部５４の側面５７および上面５８の輪郭線は曲線からなる。また、保護部５４の下面５９（挿入部５３の側を向く面）は、略平面でよい。そして、保護部５４の側面５７と下面５９とは曲面によって滑らかにつながっている。 The same shape as the first protection part 44 of the protection member 42 according to the first embodiment can be applied to the protection part 54. That is, the protection part 54 has a tapered shape whose outer diameter decreases toward the upper side (the side opposite to the insertion part 53). The side surface 57 of the protective portion 54 is formed into a curved surface that bulges outward in the radial direction and obliquely upward in a side view. The upper surface 58 (the surface opposite to the insertion section 53) of the protection section 54 is formed into a dome-shaped curved surface that bulges upward. The side surface 57 and the top surface 58 of the protection part 54 are smoothly connected by a curved surface. Thus, in side view, the contour lines of the side surface 57 and the top surface 58 of the protection part 54 are curved. Further, the lower surface 59 of the protective portion 54 (the surface facing the insertion portion 53 side) may be substantially flat. The side surface 57 and the lower surface 59 of the protection part 54 are smoothly connected by a curved surface.

したがって、本体部材４１の上端部に挿入部５３を挿入することにより、保護部材５２を本体部材４１に装着することができる。使用者は、保護部材５２を本体部材４１に装着した手押部材を、コーナ部材２２の挿入孔２３に挿入することで、手押部材を台車本体部２０に取り付けることができ、使用者は手で保護部５４に近接する本体部材４１をグリップ部として掴んで運搬台車を移動させることができる。第２の実施形態によれば、第１の実施形態と同様の効果を奏することができる。 Therefore, by inserting the insertion portion 53 into the upper end portion of the main body member 41, the protective member 52 can be attached to the main body member 41. The user can attach the hand-held member to the trolley main body 20 by inserting the hand-held member with the protection member 52 attached to the main body member 41 into the insertion hole 23 of the corner member 22, and the user The transport cart can be moved by gripping the main body member 41 close to the protection part 54 as a grip part. According to the second embodiment, the same effects as the first embodiment can be achieved.

＜第３の実施形態＞
次に、第３の実施形態に係る運搬台車および手押部材の構成について説明する。
図７は、第３の実施形態に係る運搬台車および手押部材の構成例を示す図である。なお、第１の実施形態と同様の構成は同一符号を付して、その説明を省略する。
運搬台車２は、台車本体部２０、走行部３０、手押部材６０を備えている。 <Third embodiment>
Next, a description will be given of the configurations of a transport cart and a hand-pushing member according to the third embodiment.
FIG. 7 is a diagram illustrating a configuration example of a transport cart and a hand-pushing member according to the third embodiment. Note that the same configurations as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted.
The transport truck 2 includes a truck main body 20, a running section 30, and a hand pushing member 60.

手押部材６０は、本体部としての本体部材６１と、保護部材６３と、補強部材７０とを有する。
本体部材６１は、長尺状かつパイプ状の部材である。本実施形態の本体部材６１は、第１の実施形態と異なり、軽量化を図るためにアルミニウム合金製であって、押し出し成形により形成されている。また、本実施形態の本体部材６１は、視認性を向上させるために台車本体部２０、具体的には前側フレーム部２１ａ、後側フレーム部２１ｂ、右側フレーム部２１ｃ、左側フレーム部２１ｄと異なる色が付されている。例えば、前側フレーム部２１ａ、後側フレーム部２１ｂ、右側フレーム部２１ｃ、左側フレーム部２１ｄが、シルバー等の金属色の場合には金属色とは異なる色、例えば赤、緑、青等、色の三原色であってもよく、オレンジ色等であってもよい。
また、本実施形態の本体部材６１は、使用者が掴みやすいように、外径が例えば４２～４５ｍｍ（ここでは４４ｍｍ）であり、第１の実施形態よりも小径の円管である。また、本実施形態の本体部材６１は、強度を向上させるために内部が十字状に補強されている。ただし、本体部材６１は、上述した寸法に限定されるものではなく、各種の棒状や管状の部材、上述した単管等が適用できる。 The hand-pushing member 60 includes a main body member 61 as a main body, a protection member 63, and a reinforcing member 70.
The main body member 61 is an elongated and pipe-shaped member. Unlike the first embodiment, the main body member 61 of this embodiment is made of an aluminum alloy and is formed by extrusion molding in order to reduce the weight. Furthermore, in order to improve visibility, the main body member 61 of this embodiment has a color different from that of the truck main body 20, specifically, the front frame part 21a, the rear frame part 21b, the right frame part 21c, and the left frame part 21d. is attached. For example, if the front frame part 21a, the rear frame part 21b, the right frame part 21c, and the left frame part 21d are made of a metal color such as silver, a color different from the metal color, such as red, green, or blue, may be used. The three primary colors may be used, or the color may be orange or the like.
Further, the main body member 61 of this embodiment is a circular tube having an outer diameter of, for example, 42 to 45 mm (here, 44 mm), which is smaller in diameter than that of the first embodiment, so that the user can easily grasp it. Further, the main body member 61 of this embodiment is internally reinforced in a cross shape to improve strength. However, the main body member 61 is not limited to the above-mentioned dimensions, and various rod-shaped or tubular members, the above-mentioned single tube, etc. can be applied.

図８は、手押部材６０および保護部材６３の構成例を示す図であり、（ａ）は手押部材６０の側面図、（ｂ）はＩ－Ｉ線断面図である。
保護部材６３は、使用者の手を保護すると共に、運搬物を積載するときの最大積載高さを示す指標となる。保護部材６３は、本体部材６１の上側であって、上端から所定の距離離れた位置にボルトやリベット等で固定される。本実施形態の保護部材６３は、本体部材６１の上端から１００～２００ｍｍ離れた位置に固定されるのが好適であり、更には１２０～１８０ｍｍ離れた位置に固定されるのが好適である。本体部材６１のうち、本体部材６１の上端から保護部材６３の上端までの範囲がグリップ部６２として機能する。
保護部材６３は、保護部６４と、取付部６５とを有しており、これらが一体で形成されている。また、保護部材６３は、内部に本体部材６１を挿入するために上下に開口する取付穴６６を有する。保護部材６３は、例えばポリエチレン等の樹脂材料からなり、射出成形によって一体に形成される。保護部材６３は視認性を向上させるために台車本体部２０、具体的には前側フレーム部２１ａ、後側フレーム部２１ｂ、右側フレーム部２１ｃ、左側フレーム部２１ｄと異なる色が付されている。例えば、前側フレーム部２１ａ、後側フレーム部２１ｂ、右側フレーム部２１ｃ、左側フレーム部２１ｄが、シルバー等の金属色の場合には金属色とは異なる色、例えば赤、緑、青等、色の三原色であってもよく、オレンジ色等であってもよい。なお、保護部材６３は、本体部材６１と異なる色とするが、同じ色であってもよい。 FIG. 8 is a diagram showing an example of the configuration of the hand-pushing member 60 and the protection member 63, in which (a) is a side view of the hand-pushing member 60, and (b) is a sectional view taken along the line II.
The protective member 63 protects the user's hands and serves as an index indicating the maximum loading height when loading objects. The protection member 63 is fixed to the upper side of the main body member 61 at a predetermined distance from the upper end with bolts, rivets, or the like. The protection member 63 of this embodiment is preferably fixed at a position 100 to 200 mm away from the upper end of the main body member 61, and more preferably 120 to 180 mm away. A range of the main body member 61 from the upper end of the main body member 61 to the upper end of the protective member 63 functions as a grip portion 62 .
The protection member 63 has a protection part 64 and a mounting part 65, which are integrally formed. Furthermore, the protection member 63 has a mounting hole 66 that opens upward and downward in order to insert the main body member 61 therein. The protection member 63 is made of a resin material such as polyethylene, and is integrally formed by injection molding. In order to improve visibility, the protective member 63 is colored differently from the truck main body 20, specifically, the front frame 21a, the rear frame 21b, the right frame 21c, and the left frame 21d. For example, if the front frame part 21a, the rear frame part 21b, the right frame part 21c, and the left frame part 21d are made of a metal color such as silver, a color different from the metal color, such as red, green, or blue, may be used. The three primary colors may be used, or the color may be orange or the like. Note that the protective member 63 has a different color from the main body member 61, but may have the same color.

保護部６４は、グリップ部６２の外周面よりも外側に突出する円板状であり、グリップ部６２よりも大きい外径を有する。特に、保護部６４の外径は、平面視において、グリップ部６２を掴んでいる使用者の手が保護部６４に重畳してはみ出さない（平面視において外形線の内側に収まる）寸法に設定される。具体的には、保護部６４の外径は、１００～１４０ｍｍの範囲が好適であり、更には１１０～１３０ｍｍの範囲が好適である。ただし、具体的な寸法は特に限定されるものではない。
取付部６５は、保護部６４の下端から下側に延出する円筒状であり、本体部材６１よりも大きく、保護部６４よりも小さい外径を有する。取付部６５の長さ（上下方向寸法）は、特に限定されないが、取付部６５をボルトやリベット等で本体部材６１に固定できる長さに設定される。 The protective portion 64 has a disk shape that protrudes outward from the outer circumferential surface of the grip portion 62 and has a larger outer diameter than the grip portion 62. In particular, the outer diameter of the protection part 64 is set to a size that prevents the hand of the user who is gripping the grip part 62 from overlapping and protruding from the protection part 64 when viewed from above (it fits inside the outline line when viewed from above). be done. Specifically, the outer diameter of the protective portion 64 is preferably in the range of 100 to 140 mm, more preferably in the range of 110 to 130 mm. However, the specific dimensions are not particularly limited.
The attachment part 65 has a cylindrical shape extending downward from the lower end of the protection part 64 and has an outer diameter larger than the main body member 61 and smaller than the protection part 64. The length (vertical dimension) of the attachment portion 65 is not particularly limited, but is set to a length that allows the attachment portion 65 to be fixed to the main body member 61 with bolts, rivets, or the like.

取付穴６６は、本体部材６１を挿入可能な穴である。取付穴６６の内径は、本体部材６１の外形に応じて設定される。
したがって、取付穴６６に本体部材６１を挿入して、本体部材６１の上端から所定の位置で取付部６５をボルトやリベット等で本体部材６１に固定することで、保護部材６３を本体部材６１に固定することができる。 The attachment hole 66 is a hole into which the main body member 61 can be inserted. The inner diameter of the attachment hole 66 is set according to the outer shape of the main body member 61.
Therefore, by inserting the main body member 61 into the mounting hole 66 and fixing the mounting portion 65 to the main body member 61 at a predetermined position from the upper end of the main body member 61 with bolts, rivets, etc., the protective member 63 can be attached to the main body member 61. Can be fixed.

補強部材７０は、本体部材６１の下端、具体的には下端の近接した位置にボルトやリベット等で固定される。補強部材７０は、本体部材６１の強度を補強すると共に、本体部材６１をコーナ部材２２の挿入孔２３に挿入したときに挿入孔２３との間でガタ付きを抑制する。補強部材７０は、例えばアルミニウム合金製等である。
図９は、補強部材７０の構成例を示す図であり、（ａ）は図８（ａ）に示すＩＩ－ＩＩ線断面図であり、（ｂ）はコーナ部材２２の挿入孔２３を示す図である。 The reinforcing member 70 is fixed to the lower end of the main body member 61, specifically, at a position close to the lower end with bolts, rivets, or the like. The reinforcing member 70 reinforces the strength of the main body member 61 and suppresses rattling between the main body member 61 and the insertion hole 23 when the main body member 61 is inserted into the insertion hole 23 of the corner member 22. The reinforcing member 70 is made of, for example, an aluminum alloy.
9A and 9B are diagrams showing a configuration example of the reinforcing member 70, (a) is a cross-sectional view taken along the line II-II shown in FIG. 8(a), and (b) is a diagram showing the insertion hole 23 of the corner member 22. It is.

図９（ａ）に示すように、補強部材７０は、円筒状であって、本体部材６１の外径よりも大きい外径を有する。補強部材７０は、外周面のうち一部が径方向に向かって膨らむ複数（ここでは２つ）の膨出部７１ａ、７１ｂを有する。膨出部７１ａ、７１ｂは緩やかな傾斜部７２を経て径方向に突出する。また、補強部材７０の下端は、下側に向かうにしたがって外径が小さくなる先細り形状を有する。補強部材７０の長さ（上下方向寸法）は、特に限定されないが、コーナ部材２２の挿入孔２３の深さと略同程度の長さに設定される。また、補強部材７０は、内部に本体部材６１を挿入するために上下に開口する取付穴７３を有する。
したがって、取付穴７３に本体部材６１を挿入して、本体部材６１の下端から所定の位置で補強部材７０をボルトやリベット等で本体部材６１に固定することで、補強部材７０を本体部材６１に固定することができる。 As shown in FIG. 9A, the reinforcing member 70 has a cylindrical shape and has an outer diameter larger than the outer diameter of the main body member 61. As shown in FIG. The reinforcing member 70 has a plurality of (two in this case) bulging portions 71a and 71b in which a portion of the outer circumferential surface bulges in the radial direction. The bulging portions 71a and 71b protrude in the radial direction via a gentle slope portion 72. Further, the lower end of the reinforcing member 70 has a tapered shape in which the outer diameter becomes smaller toward the lower side. The length (vertical dimension) of the reinforcing member 70 is not particularly limited, but is set to be approximately the same length as the depth of the insertion hole 23 of the corner member 22. Further, the reinforcing member 70 has a mounting hole 73 that opens upward and downward in order to insert the main body member 61 therein.
Therefore, by inserting the main body member 61 into the mounting hole 73 and fixing the reinforcing member 70 to the main body member 61 at a predetermined position from the lower end of the main body member 61 with bolts, rivets, etc., the reinforcing member 70 can be attached to the main body member 61. Can be fixed.

一方、図９（ｂ）に示すように、補強部材７０が挿入される挿入孔２３は、平面７５ａ、７５ｂ、７５ｃと、補強部材７０の円形の曲率半径と略同一の円弧面７５ｄとにより囲まれている。また、挿入孔２３には、補強部材７０の膨出部７１ａ、７１ｂの挿入を許容する凹部としての空間７６ａ、７６ｂを有する。したがって、膨出部７１ａ、７１ｂを空間７６ａ、７６ｂに合わせて、本体部材６１に固定された補強部材７０を挿入孔２３に挿入することで、手押部材６０が所定の位置に位置決めされる。 On the other hand, as shown in FIG. 9(b), the insertion hole 23 into which the reinforcing member 70 is inserted is surrounded by flat surfaces 75a, 75b, and 75c, and an arcuate surface 75d that is approximately the same radius of curvature of the reinforcing member 70. It is. Furthermore, the insertion hole 23 has spaces 76a and 76b as recesses into which the bulges 71a and 71b of the reinforcing member 70 are inserted. Therefore, by aligning the bulges 71a and 71b with the spaces 76a and 76b and inserting the reinforcing member 70 fixed to the main body member 61 into the insertion hole 23, the hand push member 60 is positioned at a predetermined position.

使用者は、保護部材６３および補強部材７０を本体部材６１に固定した手押部材６０を、コーナ部材２２の各挿入孔２３に挿入することで、手押部材６０を台車本体部２０に取り付けることができる。使用者は手で手押部材６０のグリップ部６２を掴んで運搬台車２を移動させることができる。第３の実施形態によれば、第１の実施形態と同様の効果を奏することができる。 The user attaches the hand push member 60 to the trolley main body 20 by inserting the hand push member 60 with the protection member 63 and reinforcing member 70 fixed to the main body member 61 into each insertion hole 23 of the corner member 22. Can be done. The user can move the transport cart 2 by grasping the grip portion 62 of the hand-pushing member 60 with his/her hand. According to the third embodiment, the same effects as the first embodiment can be achieved.

また、本実施形態では、単管よりも小径な本体部材６１を使用しているために、使用者は本体部材６１のグリップ部６２を容易に掴むことができる。一方、小径にしたことによる強度の低下を補強するために、本体部材６１の下端には補強部材７０を固定している。したがって、手押部材６０の強度を向上させることができる。ただし、本体部材６１に単管あるいは単管以外の部材を用いる場合であっても本体部材６１の下端に補強部材７０を固定してもよい。
また、本実施形態では、補強部材７０が挿入孔２３に挿入された状態では、補強部材７０の傾斜部７２が平面７５ｂ、７５ｃおよび円弧面７５ｄに接する。したがって、単に円形の本体部材６１を挿入する場合に比べて補強部材７０を介在させることで挿入孔２３との間の接触面積が増えるために、コーナ部材２２の挿入孔２３との間でガタ付きをより少なくすることができる。 Further, in this embodiment, since the main body member 61 is used which has a smaller diameter than a single tube, the user can easily grasp the grip portion 62 of the main body member 61. On the other hand, a reinforcing member 70 is fixed to the lower end of the main body member 61 in order to compensate for the decrease in strength due to the small diameter. Therefore, the strength of the hand-pushing member 60 can be improved. However, even if a single tube or a member other than a single tube is used for the main body member 61, the reinforcing member 70 may be fixed to the lower end of the main body member 61.
Furthermore, in this embodiment, when the reinforcing member 70 is inserted into the insertion hole 23, the inclined portion 72 of the reinforcing member 70 is in contact with the flat surfaces 75b, 75c and the circular arc surface 75d. Therefore, compared to simply inserting the circular main body member 61, the interposition of the reinforcing member 70 increases the contact area between the corner member 22 and the insertion hole 23. can be made smaller.

また、図８（ｂ）に示す平面視において、保護部６４の一部は台車本体部２０（二点鎖線を参照）と重畳する。したがって、台車本体部２０に運搬物を積載するときに運搬物と保護部６４とが干渉するために、運搬物を保護部６４よりも高く積載されることを防止できる。すなわち、保護部６４は最大積載高さを示す指標となる。したがって、使用者は運搬物を積載した運搬台車２の重心位置が高くなることが抑制でき、使用者は運搬台車２を安定して走行させることができる。なお、使用者に保護部６４が最大積載高さを示す指標であることを報知するために、保護部６４を超えて運搬物を積載してはいけない旨がシール等で手押部材６０あるいは台車本体部２０等に付されている。
なお、保護部材６３は本体部材６１の上端から所定の距離離れた位置で、取付穴６６の軸線を中心にして本体部材６１に対して回動自在に配置してもよい。この場合、保護部材６３の保護部６４が壁等の物体Ｗに接触したときに保護部材６３が回動して、接触したときの衝撃を抑制することができる。 Further, in a plan view shown in FIG. 8(b), a portion of the protection portion 64 overlaps with the truck main body portion 20 (see the two-dot chain line). Therefore, since the object to be transported and the protection part 64 interfere with each other when the object is loaded onto the trolley body 20, it is possible to prevent the object from being loaded higher than the protection part 64. In other words, the protection portion 64 serves as an index indicating the maximum loading height. Therefore, the user can prevent the center of gravity of the transport trolley 2 loaded with objects from becoming high, and the user can run the transport trolley 2 stably. In addition, in order to inform the user that the protection part 64 is an indicator indicating the maximum loading height, a sticker or the like is placed on the hand push member 60 or the trolley to the effect that objects must not be loaded beyond the protection part 64. It is attached to the main body part 20 and the like.
Note that the protection member 63 may be arranged at a position a predetermined distance away from the upper end of the main body member 61 so as to be rotatable with respect to the main body member 61 about the axis of the attachment hole 66 . In this case, when the protection part 64 of the protection member 63 comes into contact with the object W such as a wall, the protection member 63 rotates, and the impact upon contact can be suppressed.

＜第４の実施形態＞
次に、第４の実施形態に係る運搬台車および手押部材の構成について説明する。
図１０は、第４の実施形態に係る運搬台車および手押部材の構成例を示す図である。なお、第３の実施形態と同様の構成は同一符号を付して、その説明を省略する。
運搬台車３は、台車本体部２０、走行部３０、手押部材８０（８０ａ～８０ｄ）を備えている。 <Fourth embodiment>
Next, a description will be given of the configurations of a transport cart and a hand-pushing member according to the fourth embodiment.
FIG. 10 is a diagram illustrating an example of the configuration of a transport cart and a hand-pushing member according to the fourth embodiment. Note that configurations similar to those in the third embodiment are denoted by the same reference numerals, and description thereof will be omitted.
The transport truck 3 includes a truck body 20, a running section 30, and a hand push member 80 (80a to 80d).

手押部材８０は、本体部としての本体部材６１と、保護部材８３と、補強部材７０とを有する。なお、本体部材６１と補強部材７０とは、第３の実施形態と同一の部材を用いることができる。
図１１は、手押部材８０および保護部材８３の構成例を示す図であり、（ａ）は手押部材８０の側面図、（ｂ）はＩＩＩ－ＩＩＩ線断面図である。
保護部材８３は、使用者の手を保護すると共に、側壁を取り付けるための側壁取付部として機能する。保護部材８３は、本体部材６１の上下に離れた複数（ここでは、２箇所）の位置にボルトやリベット等で固定される。具体的には、一つ目の保護部材８３は、上側であって、上端から所定の距離、離れた位置にボルトやリベット等で固定される。この位置は、グリップ部６２に近接した位置である。一方、二つ目の保護部材８３は、下側であって、下端から所定の距離、離れた位置にボルトやリベット等で固定される。この位置は、補強部材７０に近接した位置である。 The hand-pushing member 80 includes a main body member 61 as a main body, a protection member 83, and a reinforcing member 70. Note that the same members as in the third embodiment can be used for the main body member 61 and the reinforcing member 70.
FIG. 11 is a diagram showing an example of the configuration of the hand-holding member 80 and the protection member 83, in which (a) is a side view of the hand-holding member 80, and (b) is a sectional view taken along the line III-III.
The protection member 83 protects the user's hands and functions as a side wall attachment portion for attaching the side wall. The protection member 83 is fixed to the main body member 61 at a plurality of vertically separated positions (in this case, two positions) with bolts, rivets, or the like. Specifically, the first protection member 83 is fixed on the upper side at a predetermined distance from the upper end with bolts, rivets, or the like. This position is close to the grip portion 62. On the other hand, the second protection member 83 is fixed on the lower side at a predetermined distance from the lower end with bolts, rivets, or the like. This position is close to the reinforcing member 70.

保護部材８３は、保護部８４と、取付部６５とを有しており、これらが一体で形成されている。また、保護部材８３は、内部に本体部材６１を挿入するために上下に開口する取付穴６６を有する。保護部材８３は、例えばポリエチレン等の樹脂材料からなり、射出成形によって一体に形成される。保護部材８３は視認性を向上させるために、第３の実施形態の保護部材６３と同様な色が付されている。 The protection member 83 has a protection portion 84 and a mounting portion 65, which are integrally formed. Furthermore, the protection member 83 has a mounting hole 66 that opens upward and downward in order to insert the main body member 61 therein. The protection member 83 is made of a resin material such as polyethylene, and is integrally formed by injection molding. The protective member 83 is colored similarly to the protective member 63 of the third embodiment in order to improve visibility.

保護部８４は、グリップ部６２の外周面よりも外側に突出する複数（ここでは４つ）の突出部８５ａ～８５ｄを有する。突出部８５ａ～８５ｄは、取付穴６６の上下方向に沿った軸線（中心軸線）を中心として９０°の等間隔であって、取付穴６６の軸線側から径方向に放射状に延びている。また、突出部８５ａ～８５ｄは、外側の外形線が略円形（以下、突出部８５ａ～８５ｄの円形という）の一部をなしている。突出部８５ａ～８５ｄの円形は、グリップ部６２よりも大きい外径を有する。特に、突出部８５ａ～８５ｄの外径は、平面視において、グリップ部６２を掴んでいる使用者の手が保護部８４に重畳してはみ出さない（平面視において外形線の内側に収まる）寸法に設定される。具体的には、突出部８５ａ～８５ｄの円形の外径は、１００～１４０ｍｍの範囲が好適であり、更には１１０～１３０ｍｍの範囲が好適である。ただし、具体的な寸法は特に限定されるものではない。 The protective portion 84 has a plurality of (here, four) protrusions 85a to 85d that protrude outward from the outer peripheral surface of the grip portion 62. The protrusions 85a to 85d extend radially from the axis of the mounting hole 66 at equal intervals of 90° about the vertical axis (center axis) of the mounting hole 66. Further, the outer outline of the protrusions 85a to 85d forms part of a substantially circular shape (hereinafter referred to as the circular shape of the protrusions 85a to 85d). The circular shapes of the protruding parts 85a to 85d have a larger outer diameter than the grip part 62. In particular, the outer diameters of the protruding portions 85a to 85d are such that the user's hand holding the grip portion 62 does not overlap and protrude from the protective portion 84 when viewed from above (the outer diameter is within the outer contour line when viewed from above). is set to Specifically, the circular outer diameter of the protrusions 85a to 85d is preferably in the range of 100 to 140 mm, more preferably in the range of 110 to 130 mm. However, the specific dimensions are not particularly limited.

また、保護部８４は、隣接する突出部８５ａ～８５ｄの間に、外側から保護部８４の中心側、すなわち内側に向かって凹む溝部８６ａ～８６ｄを有する。溝部８６ａ～８６ｄは、取付穴６６の軸線（中心軸線）を中心として９０°の等間隔に形成される。溝部８６ａ～８６ｄは保護部８４を上下に貫通する。また、溝部８６ａ～８６ｄの溝幅（図１１（ｂ）に示すＷ）は、後述する側壁を嵌め込むことができる寸法に設定される。更に、溝部８６ａ～８６ｄには、外側に向かうほど溝幅が広がるように開拡する傾斜状あるいは円弧状の支持部８７ａ～８７ｄを有する。 Furthermore, the protective portion 84 has groove portions 86a to 86d that are recessed from the outside toward the center of the protective portion 84, that is, toward the inside, between the adjacent protrusions 85a to 85d. The grooves 86a to 86d are formed at equal intervals of 90° around the axis (center axis) of the mounting hole 66. The groove portions 86a to 86d vertically penetrate the protective portion 84. Further, the width of the grooves 86a to 86d (W shown in FIG. 11(b)) is set to a size in which a side wall, which will be described later, can be fitted therein. Further, the groove portions 86a to 86d have inclined or arcuate support portions 87a to 87d that widen and widen so that the groove width increases toward the outside.

ここで、一つ目の保護部材８３および二つ目の保護部材８３の各取付穴６６に本体部材６１を挿入して、本体部材６１の上端から所定の位置および下端から所定の位置で各取付部６５をボルトやリベット等で本体部材６１に固定することで、２つの保護部材８３を本体部材６１に固定することができる。このとき、手押部材８０の平面視において、２つの保護部材８３はそれぞれの溝部８６ａ～８６ｄが重畳する状態で本体部材６１に固定される。 Here, the main body member 61 is inserted into each mounting hole 66 of the first protection member 83 and the second protection member 83, and each mounting is performed at a predetermined position from the upper end of the main body member 61 and from a predetermined position from the lower end. The two protection members 83 can be fixed to the main body member 61 by fixing the portions 65 to the main body member 61 with bolts, rivets, or the like. At this time, the two protection members 83 are fixed to the main body member 61 in a state in which the respective grooves 86a to 86d overlap with each other in a plan view of the pusher member 80.

使用者は、保護部材８３および補強部材７０を本体部材６１に固定した手押部材８０を、コーナ部材２２の各挿入孔２３に挿入することで、手押部材８０を台車本体部２０に取り付けることができる。このとき、各手押部材８０における溝部８６ａ～８６ｄがそれぞれ運搬台車３の前後方向および左右方向を指向するように、補強部材７０によって位置決めされる。また、図１１（ｂ）に示す平面視において、手押部材８０ｂを一例にすると、溝部８６ａ～８６ｄのうち溝部８６ａ、８６ｂが台車本体部２０（二点鎖線を参照）と重畳する。 The user attaches the hand push member 80 to the trolley main body 20 by inserting the hand push member 80 with the protection member 83 and the reinforcing member 70 fixed to the main body member 61 into each insertion hole 23 of the corner member 22. Can be done. At this time, the reinforcing member 70 positions the grooves 86a to 86d in each hand pushing member 80 so that they are oriented in the front-rear direction and left-right direction of the transport vehicle 3, respectively. Further, in a plan view shown in FIG. 11(b), taking the hand push member 80b as an example, grooves 86a and 86b of the grooves 86a to 86d overlap with the truck main body 20 (see the two-dot chain line).

図１２は、側壁９０Ａ～９０Ｄを取り付けた運搬台車３の構成例を示す斜視図である。
側壁９０Ａ～９０Ｄは、矩形の板状であって、それぞれ前後左右から運搬台車３の側方を覆う。側壁９０Ａ～９０Ｄは、例えばプラスチックダンボールが用いられる。プラスチックダンボールは、プラスチックを素材とし、中空の領域を備える板状の部材であり、軽量であって剛性に優れている。ただし、側壁９０Ａ～９０Ｄは、木材の合板や単板等を用いてもよい。 FIG. 12 is a perspective view showing an example of the configuration of the transport vehicle 3 to which side walls 90A to 90D are attached.
The side walls 90A to 90D have a rectangular plate shape, and cover the sides of the transport vehicle 3 from the front, rear, left and right sides, respectively. For example, plastic cardboard is used for the side walls 90A to 90D. Plastic cardboard is a plate-shaped member that is made of plastic and has a hollow area, and is lightweight and has excellent rigidity. However, the side walls 90A to 90D may be made of plywood, veneer, or the like.

ここで、側壁９０Ａ～９０Ｄの板厚は、溝部８６ａ～８６ｄに嵌め込むことができる寸法に設定される。また、側壁９０Ａ～９０Ｄの高さは、載置板２６から上側に位置する保護部材８３の保護部８４までの距離と略同一である。また、側壁９０Ａ，９０Ｂの長さ（左右方向の長さ）は、前側フレーム部２１ａあるいは後側フレーム部２１ｂの長さと略同一である。また、側壁９０Ｃ，９０Ｄの長さ（前後方向の長さ）は、右側フレーム部２１ｃあるいは左側フレーム部２１ｄの長さと略同一である。 Here, the thickness of the side walls 90A to 90D is set to a size that allows them to be fitted into the grooves 86a to 86d. Further, the heights of the side walls 90A to 90D are approximately the same as the distance from the mounting plate 26 to the protection portion 84 of the protection member 83 located above. Further, the length of the side walls 90A and 90B (length in the left-right direction) is approximately the same as the length of the front frame portion 21a or the rear frame portion 21b. Further, the lengths of the side walls 90C and 90D (length in the front-rear direction) are approximately the same as the lengths of the right frame portion 21c or the left frame portion 21d.

次に、側壁９０Ａ～９０Ｄを運搬台車３に取り付ける場合について説明する。説明の便宜上、側壁９０Ａ～９０Ｄが運搬台車３に取り付けられた状態において、側壁９０Ａ～９０Ｄの矩形の４辺のうち上側に位置する辺を上辺、下側に位置する辺を底辺、鉛直方向の２つの辺を側辺という。
まず、使用者は側壁９０Ａ～９０Ｄの面がそれぞれ鉛直になるように維持する。次に、使用者は、手押部材８０ｄと手押部材８０ａとの間、手押部材８０ａと手押部材８０ｂとの間、手押部材８０ｂと手押部材８０ｃとの間、および、手押部材８０ｃと手押部材８０ｄとの間に、上側から各側壁９０Ａ～９０Ｄを挿入する。このとき、側壁９０Ａ～９０Ｄの両側の側辺を手押部材８０ａ～８０ｄの溝部８６ａ～８６ｄに嵌め込みながら挿入する。側壁９０Ａ～９０Ｄを挿入することで、側壁９０Ａ～９０Ｄの各底辺が載置板２６（あるいはフレーム部）の上面によって支持される。 Next, the case where the side walls 90A to 90D are attached to the transport vehicle 3 will be described. For convenience of explanation, when the side walls 90A to 90D are attached to the transport trolley 3, the upper side of the four rectangular sides of the side walls 90A to 90D is referred to as the upper side, the lower side is referred to as the bottom side, and the vertical side is referred to as the bottom side. The two sides are called sides.
First, the user maintains the sides of the side walls 90A to 90D so that they are vertical. Next, the user moves between the hand push member 80d and the hand push member 80a, between the hand push member 80a and the hand push member 80b, between the hand push member 80b and the hand push member 80c, and between the hand push member 80b and the hand push member 80c. Each of the side walls 90A to 90D is inserted from above between the member 80c and the pusher member 80d. At this time, the side walls 90A to 90D are inserted while being fitted into the grooves 86a to 86d of the hand pushing members 80a to 80d. By inserting the side walls 90A to 90D, the bottom sides of the side walls 90A to 90D are supported by the upper surface of the mounting plate 26 (or the frame portion).

側壁９０Ａ～９０Ｄが載置板２６上に支持された状態では、側壁９０Ａ～９０Ｄの各側辺は手押部材８０ａ～８０ｄの上側に位置する保護部材８３の溝部８６ａ～８６ｄ、および、下側に位置する保護部材８３の溝部８６ａ～８６ｄに嵌め込まれる。
図１１（ｂ）に示すように手押部材８０ｂを一例にすると、上側および下側の保護部材８３の何れについても、保護部８４の溝部８６ａに側壁９０Ｄの一方側の側辺が嵌め込まれ、保護部８４の溝部８６ｄに側壁９０Ｂの一方側の側辺が嵌め込まれる。同様に、手押部材８０ａ、８０ｂ、８０ｄについても、上下の位置で側辺がそれぞれ２つの溝部８６ａ～８６ｄに嵌め込まれる。したがって、側壁９０Ａ～９０Ｄは、手押部材８０ａ～８０ｄの保護部８４によって運搬台車３に取り付けられる。 In a state where the side walls 90A to 90D are supported on the mounting plate 26, each side of the side walls 90A to 90D is connected to the grooves 86a to 86d of the protection member 83 located above the push members 80a to 80d, and the lower side of the side walls 90A to 90D. It is fitted into the grooves 86a to 86d of the protection member 83 located at.
As shown in FIG. 11(b), taking the hand push member 80b as an example, one side of the side wall 90D is fitted into the groove 86a of the protection part 84 for both the upper and lower protection members 83, One side of the side wall 90B is fitted into the groove 86d of the protection portion 84. Similarly, the side edges of the push members 80a, 80b, and 80d are fitted into the two grooves 86a to 86d, respectively, at the upper and lower positions. Therefore, the side walls 90A to 90D are attached to the transport carriage 3 by the protection portions 84 of the push members 80a to 80d.

側壁９０Ａ～９０Ｄが取り付けられた運搬台車３は、側壁９０Ａ～９０Ｄによって囲まれた空間内に運搬物を収容することができる。運搬台車３の側方を覆うように側壁９０Ａ～９０Ｄを取り付けることで、運搬物を落下させることなく運搬台車３を走行させることができる。すなわち、使用者は手で手押部材８０のグリップ部６２を掴んで運搬台車３を移動させることができる。このとき、運搬台車３の手押部材４０を掴んでいる使用者の手Ｈに物体Ｗに接近した場合であっても、上側の保護部材８３の保護部８４が物体Ｗに接触するため、グリップ部６２を掴んでいる使用者の手Ｈが物体Ｗに接触することが防止または抑制される。 The transport cart 3 to which the side walls 90A to 90D are attached can accommodate objects to be transported within a space surrounded by the side walls 90A to 90D. By attaching the side walls 90A to 90D so as to cover the sides of the transport vehicle 3, the transport vehicle 3 can be run without dropping the objects to be transported. That is, the user can move the transport cart 3 by grasping the grip portion 62 of the hand-pushing member 80 with his or her hand. At this time, even if the user's hand H, which is gripping the hand push member 40 of the transport vehicle 3, approaches the object W, the protection part 84 of the upper protection member 83 comes into contact with the object W, so the grip The user's hand H holding the portion 62 is prevented or suppressed from coming into contact with the object W.

また、本実施形態の手押部材８０は、手押部材８０を保管したり搬送したりする場合に、複数の手押部材８０を積み重ねた状態に支持することができる。
図１３は手押部材８０を積み重ねた状態を示す図であり、（ａ）は側面図、（ｂ）は（ａ）に示す矢印Ａ方向から見た図である。
図１３（ａ）に示すように、手押部材８０を積み重ねるには、各手押部材８０の長手方向を水平にした状態で並列になるように複数段に重ねる。このとき、並列で隣り合う手押部材８０同士は、保護部材８３が鉛直方向に重ならないように手押部材８０の長手方向に互い違いにずらして重ねる。 Further, the hand-pushing member 80 of this embodiment can support a plurality of hand-pushing members 80 in a stacked state when storing or transporting the hand-pushing members 80.
13A and 13B are diagrams showing a stacked state of the hand press members 80, in which (a) is a side view and (b) is a view seen from the direction of arrow A shown in (a).
As shown in FIG. 13(a), in order to stack the hand-push members 80, they are stacked in multiple stages so that they are parallel to each other with the longitudinal direction of each hand-push member 80 being horizontal. At this time, the hand press members 80 that are adjacent to each other in parallel are overlapped with each other in a staggered manner in the longitudinal direction of the hand press members 80 so that the protection members 83 do not overlap in the vertical direction.

図１３（ｂ）に示すように、１段目の手押部材８０は、保護部材８３の保護部８４の２つの突出部（ここでは、突出部８５ｂ、８５ｃ）が床面に接地する。したがって、１段目の手押部材８０は床面に安定した状態で接地される。次に、積み重ねた２段目の手押部材８０は、保護部８４の２つの突出部（ここでは、突出部８５ｂ、８５ｃ）の間に形成されている支持部（ここでは、支持部８７ｃ）が、１段目の手押部材８０の本体部材６１の外周面に接する。また、１段目の手押部材８０は、保護部８４の２つの突出部（ここでは、突出部８５ａ、８５ｄ）の間に形成されている支持部（ここでは、支持部８７ａ）が、２段目の手押部材８０の本体部材６１の外周面、正確には取付部６５の外周面に接する。このように、複数の手押部材８０を積み重ねるときに、手押部材８０の保護部８４は、並列で隣り合う手押部材８０を支持するための支持部８７ａ～８７ｄを有する。したがって、複数の手押部材８０を安定して積み重ねることができる。 As shown in FIG. 13(b), in the first stage hand-pushing member 80, two protrusions (here, protrusions 85b and 85c) of the protection portion 84 of the protection member 83 are in contact with the floor surface. Therefore, the first stage hand push member 80 is stably grounded on the floor surface. Next, the stacked second hand member 80 has a support part (here, the support part 87c) formed between the two protrusions (here, the protrusions 85b and 85c) of the protection part 84. is in contact with the outer circumferential surface of the main body member 61 of the first stage pusher member 80. In addition, the first-stage hand-pushing member 80 has a support portion (here, the support portion 87a) formed between the two protrusions (here, the protrusions 85a and 85d) of the protection portion 84; It contacts the outer circumferential surface of the main body member 61 of the hand push member 80 in the step, more precisely, the outer circumferential surface of the attachment portion 65 . In this way, when stacking a plurality of hand-push members 80, the protection portion 84 of the hand-push member 80 has support portions 87a to 87d for supporting hand-push members 80 adjacent to each other in parallel. Therefore, a plurality of push members 80 can be stacked stably.

なお、手押部材８０を２段で積み重ねる場合に限られず、図１３の二点鎖線で示すように３段で積み重ねてもよく、４段以上に積み重ねてもよい。また、支持部８７ａ～８７ｄは、外側に向かうほど溝幅が広がるように開拡する傾斜状あるいは円弧状である場合に限られず、隣り合う手押部材８０の本体部材６１を支持可能な形状であればよい。 Note that the hand push members 80 are not limited to being stacked in two stages, but may be stacked in three stages as shown by the two-dot chain line in FIG. 13, or may be stacked in four or more stages. Further, the support portions 87a to 87d are not limited to an inclined shape or an arc shape that expands so that the groove width increases toward the outside, but may have a shape that can support the main body member 61 of the adjacent hand push member 80. Good to have.

＜第５の実施形態＞
次に、第５の実施形態に係る手押部材の構成について説明する。
図１４は、第５の実施形態に係る手押部材の構成例を示す図である。本実施形態の手押部材１００は、第３の実施形態で説明した手押部材６０を改良したものであり、手押部材６０と同様の構成は同一符号を付して、その説明を省略する。 <Fifth embodiment>
Next, the configuration of the hand-pushing member according to the fifth embodiment will be described.
FIG. 14 is a diagram showing a configuration example of a hand-pushing member according to the fifth embodiment. The hand-pushing member 100 of this embodiment is an improved version of the hand-pushing member 60 described in the third embodiment, and the same components as the hand-pushing member 60 are given the same reference numerals, and the explanation thereof will be omitted. .

手押部材１００は、本体部材１１０と、保護部材６３と、補強部材７０とを有し、長手方向に伸縮可能である。
本体部材１１０は、第１の本体部１１１ａと、第２の本体部１１１ｂとを有する。第１の本体部１１１ａおよび第２の本体部１１１ｂは、長尺状かつパイプ状の部材であり、例えばアルミニウム合金製である。第１の本体部１１１ａは本体部材１１０の上側を構成し、第２の本体部１１１ｂは本体部材１１０の下側を構成する。 The hand-pushing member 100 includes a main body member 110, a protection member 63, and a reinforcing member 70, and is expandable and contractible in the longitudinal direction.
The main body member 110 has a first main body portion 111a and a second main body portion 111b. The first main body portion 111a and the second main body portion 111b are elongated and pipe-shaped members, and are made of, for example, an aluminum alloy. The first body portion 111a constitutes the upper side of the body member 110, and the second body portion 111b constitutes the lower side of the body member 110.

第１の本体部１１１ａは、上端から所定の位置に保護部材６３が固定される。また、第１の本体部１１１ａの上端から保護部材６３の上端までの範囲がグリップ部６２として機能する。一方、第２の本体部１１１ｂは、下端の近接した位置にボルトやリベット等で補強部材７０が固定される。
ここで、第１の本体部１１１ａは第２の本体部１１１ｂの内径よりも小さい外径を有し、第２の本体部１１１ｂは第１の本体部１１１ａの外径よりも大きい内径を有する。すなわち、第１の本体部１１１ａの下端は、第２の本体部１１１ｂの上端側から第２の本体部１１１ｂ内に挿入可能である。したがって、第２の本体部１１１ｂに対して第１の本体部１１１ａを挿入する長さ、すなわち重なり合う長さを変えることで本体部材１１０の長手方向の長さを伸縮できる。 A protection member 63 is fixed at a predetermined position from the upper end of the first main body portion 111a. Further, the range from the upper end of the first main body portion 111a to the upper end of the protective member 63 functions as the grip portion 62. On the other hand, a reinforcing member 70 is fixed to the second main body portion 111b at a position close to the lower end with bolts, rivets, or the like.
Here, the first main body part 111a has an outer diameter smaller than the inner diameter of the second main body part 111b, and the second main body part 111b has an inner diameter larger than the outer diameter of the first main body part 111a. That is, the lower end of the first body part 111a can be inserted into the second body part 111b from the upper end side of the second body part 111b. Therefore, by changing the insertion length of the first body part 111a into the second body part 111b, that is, the overlapping length, the length in the longitudinal direction of the body member 110 can be expanded or contracted.

また、本体部材１１０は、第１の本体部１１１ａと第２の本体部１１１ｂとが重なり合う位置に、本体部材１１０を伸縮した長さに保持する保持機構１１２を有する。保持機構１１２は、第１の本体部１１１ａの外周面に形成された複数の調整孔１１３と、第２の本体部１１１ｂの外周面に形成された一つの挿通孔１１４と、調整孔１１３および挿通孔１１４に挿通させる挿通ピン１１５とを有する。本体部材１１０を所望の長さで保持する場合には、本体部材１１０を伸縮した上で、挿通ピン１１５を挿通孔１１４と調整孔１１３に挿通させることで、本体部材１１０を伸縮した長さに保持することができる。 Further, the main body member 110 includes a holding mechanism 112 that holds the main body member 110 at an expanded and contracted length at a position where the first main body portion 111a and the second main body portion 111b overlap. The holding mechanism 112 includes a plurality of adjustment holes 113 formed on the outer peripheral surface of the first main body part 111a, one insertion hole 114 formed on the outer peripheral surface of the second main body part 111b, and a plurality of adjustment holes 113 and the insertion hole 114 formed on the outer peripheral surface of the second main body part 111b. It has an insertion pin 115 that is inserted into the hole 114. When holding the main body member 110 at a desired length, the main body member 110 is expanded and contracted, and then the insertion pin 115 is inserted through the insertion hole 114 and the adjustment hole 113, thereby holding the main body member 110 at the expanded and contracted length. can be retained.

このように、手押部材１００は、本体部材１１０によって長手方向の長さが伸縮可能である。本体部材１１０の長さを伸縮させることで、保護部材６３の保護部６４の位置を上下方向に調整することができる。したがって、保護部６４を最大積載高さの指標として用いる場合には、必要に応じて保護部６４の位置を上下に調整することができる。例えば、台車本体部２０のサイズに応じて安定して走行できる最大積載高さが異なるために、取り付ける台車本体部２０のサイズに応じて、手押部材１００を伸縮させて最大積載高さの指標である保護部６４を上下に変更することができる。また、例えば、使用者が属する団体（あるいは建設現場）毎に最大積載高さの基準が異なる場合があることから、製造者は団体（あるいは建設現場）毎に最大積載高さの指標である保護部６４を上下に変更して手押部材１００を製造することができる。 In this way, the hand-push member 100 can be expanded and contracted in length in the longitudinal direction by the main body member 110. By expanding and contracting the length of the main body member 110, the position of the protective portion 64 of the protective member 63 can be adjusted in the vertical direction. Therefore, when using the protection part 64 as an indicator of the maximum loading height, the position of the protection part 64 can be adjusted up or down as necessary. For example, since the maximum loading height that can be stably traveled differs depending on the size of the truck body 20, the hand push member 100 is expanded or contracted depending on the size of the truck body 20 to be attached, and the maximum loading height is determined as an index. The protective portion 64 can be changed vertically. In addition, for example, since standards for the maximum loading height may differ depending on the organization (or construction site) to which the user belongs, manufacturers may also The hand push member 100 can be manufactured by changing the portion 64 up and down.

なお、本実施形態では、保持機構１１２が、挿通ピン１１５を挿通孔１１４と調整孔１１３に挿通させることで、本体部材１１０を伸縮した長さに保持する場合について説明したが、この場合に限られず、不用意に長さが変更されないように保持できれば、どのような保持機構であってもよい。
また、本実施形態では、第３の実施形態で説明した手押部材６０を伸縮可能にした手押部材１００について説明したが、この場合に限られず、他の実施形態の手押部材を伸縮可能にしてもよい。第１の実施形態の手押部材４０を伸縮可能にした場合には、グリップ部４３の高さを調整することができる。また、第４の実施形態の手押部材８０を伸縮可能にした場合には、上述した側壁９０Ａ～９０Ｄの高さとは異なる高さの側壁を取り付けることができる。 In this embodiment, a case has been described in which the holding mechanism 112 holds the main body member 110 at the expanded and contracted length by inserting the insertion pin 115 into the insertion hole 114 and the adjustment hole 113. However, this is not limited to this case. Any holding mechanism may be used as long as it can be held so that the length is not changed inadvertently.
Further, in this embodiment, the hand push member 100 that is made expandable and retractable is the hand push member 60 described in the third embodiment, but this is not limited to this case, and hand push members of other embodiments can be extended and contracted. You can also do this. When the hand press member 40 of the first embodiment is made expandable and retractable, the height of the grip portion 43 can be adjusted. Further, when the hand push member 80 of the fourth embodiment is made expandable and retractable, side walls having a height different from the heights of the above-mentioned side walls 90A to 90D can be attached.

＜第６の実施形態＞
次に、第６の実施形態に係る手押部材の構成について説明する。
本実施形態の手押部材１２０は、第４の実施形態で説明した手押部材８０を改良したものである。ここでは、改良した点を中心に説明し、手押部材８０と同様の構成は同一符号を付す等して説明を適宜、省略する。 <Sixth embodiment>
Next, the configuration of the hand-pushing member according to the sixth embodiment will be described.
The hand-push member 120 of this embodiment is an improved version of the hand-push member 80 described in the fourth embodiment. Here, the explanation will focus on the improved points, and the same components as the hand-pushing member 80 will be given the same reference numerals, and the explanation will be omitted as appropriate.

手押部材１２０は、本体部としての本体部材６１と、保護部材１２３と、補強部材７０とを有する。なお、本体部材６１と補強部材７０とは、第３の実施形態と同一の部材を用いることができる。
図１５は、保護部材１２３の構成例を示す斜視図である。
保護部材１２３は、使用者の手を保護すると共に、側壁を取り付けるための側壁取付部として機能する。保護部材１２３は、保護部１２４を有している。 The hand-pushing member 120 includes a main body member 61 as a main body, a protection member 123, and a reinforcing member 70. Note that the same members as in the third embodiment can be used for the main body member 61 and the reinforcing member 70.
FIG. 15 is a perspective view showing a configuration example of the protection member 123.
The protective member 123 protects the user's hands and functions as a side wall attachment portion for attaching the side wall. The protection member 123 has a protection part 124.

保護部１２４は、グリップ部６２の外周面よりも外側に突出する複数（ここでは４つ）の突出部８５ａ～８５ｄを有する。
また、保護部１２４は、隣接する突出部８５ａ～８５ｄの間に、外側から保護部８４の中心側、すなわち内側に向かって凹む溝部１２６ａ～１２６ｄを有する。溝部１２６ａ～１２６ｄは、取付穴６６の軸線（中心軸線）を中心にして略９０°の間隔に形成される。溝部１２６ａ～１２６ｄは保護部１２４を上下に貫通する。 The protective portion 124 has a plurality of (here, four) protrusions 85a to 85d that protrude outward from the outer peripheral surface of the grip portion 62.
Furthermore, the protective portion 124 has groove portions 126a to 126d that are recessed from the outside toward the center of the protective portion 84, that is, toward the inside, between the adjacent protrusions 85a to 85d. The grooves 126a to 126d are formed at intervals of approximately 90° about the axis (center axis) of the mounting hole 66. The groove portions 126a to 126d vertically penetrate the protective portion 124.

本実施形態の溝部１２６ａ～１２６ｄは、板厚の異なる２種類の側壁を取り付けることができるように設定される。具体的には、溝部１２６ａ、１２６ｂの溝幅は板厚の厚い側壁を嵌め込むことができる寸法Ｗ１に設定される。また、溝部１２６ｃ、１２６ｄの溝幅は板厚の薄い側壁を嵌め込むことができる寸法Ｗ２に設定される。寸法Ｗ１と寸法Ｗ２との関係は、Ｗ１＞Ｗ２である。ここで、一つの溝部に注目したとき、注目した溝部の溝幅は、隣り合う溝部のうち一方の溝部の溝幅と略同一であり、他方の溝部の溝幅とは異なる。
なお、各溝部１２６ａ～１２６ｄと保護部１２４の上面との境界には、側壁を上側から容易に嵌め込むことができるように、上側に向かうほど溝幅が広がるように傾斜部１２７を有する。 The grooves 126a to 126d of this embodiment are set so that two types of side walls having different thicknesses can be attached. Specifically, the groove width of the groove portions 126a and 126b is set to a dimension W1 in which a thick side wall can be fitted. Further, the width of the groove portions 126c and 126d is set to a dimension W2 in which a thin side wall can be fitted. The relationship between the dimension W1 and the dimension W2 is W1>W2. Here, when focusing on one groove, the groove width of the focused groove is approximately the same as the groove width of one of the adjacent grooves, and different from the groove width of the other groove.
Incidentally, the boundary between each of the grooves 126a to 126d and the upper surface of the protection portion 124 has an inclined portion 127 such that the groove width increases toward the top so that the side wall can be easily fitted from above.

ここで、２つの保護部材１２３を本体部材６１に固定する場合、手押部材１２０の平面視において、それぞれの溝部１２６ａ～１２６ｄが重畳する状態で本体部材６１に固定される。
使用者は、保護部材１２３および補強部材７０を本体部材６１に固定した手押部材１２０を、コーナ部材２２の各挿入孔２３に挿入することで、手押部材１２０を台車本体部２０に取り付けることができる。このとき、運搬台車３に取り付ける側壁の板厚に応じて、各手押部材１２０における溝部１２６ａ～１２６ｄがそれぞれ運搬台車３の前後方向および左右方向を指向するように、補強部材７０によって位置決めされる。 Here, when the two protection members 123 are fixed to the main body member 61, they are fixed to the main body member 61 in a state in which the respective grooves 126a to 126d overlap in a plan view of the pusher member 120.
The user attaches the hand push member 120 to the trolley main body 20 by inserting the hand push member 120 with the protection member 123 and the reinforcing member 70 fixed to the main body member 61 into each insertion hole 23 of the corner member 22. Can be done. At this time, the reinforcing member 70 positions the grooves 126a to 126d of each hand-pushing member 120 in accordance with the thickness of the side wall attached to the carrier 3 so that they are oriented in the front-rear direction and the left-right direction of the carrier 3, respectively. .

図１６は、運搬台車３に板厚が厚い側壁９１Ａ～９１Ｄを取り付ける場合に、手押部材１２０を位置決めする向きを説明するための平面図である。ここで、板厚が厚い側壁９１Ａ～９１Ｄとして、例えばプラスチックダンボール等が用いられる。
板厚が厚い側壁９１Ａ～９１Ｄを取り付ける場合には、保護部１２４の溝部１２６ａ、１２６ｂが台車本体部２０と重畳するように手押部材１２０をそれぞれコーナ部材２２に位置決めする。したがって、平面視において４隅に位置する保護部１２４のうち、隣り合う保護部１２４同士では、溝幅が寸法Ｗ１である溝部１２６ａと溝幅が寸法Ｗ１である溝部１２６ｂとが対向する。
使用者は、手押部材１２０ｄの溝部１２６ａと手押部材１２０ａの溝部１２６ｂとの間、手押部材１２０ａの溝部１２６ａと手押部材１２０ｂの溝部１２６ｂとの間、手押部材１２０ｂの溝部１２６ａと手押部材１２０ｃの溝部１２６ｂとの間、および、手押部材１２０ｃの溝部１２６ａと手押部材１２０ｄの溝部１２６ｂとの間に、上側から各側壁９１Ａ～９１Ｄを挿入する。したがって、板厚の厚い側壁９１Ａ～９１Ｄは、手押部材１２０ａ～１２０ｄの保護部１２３によって運搬台車３に取り付けられる。 FIG. 16 is a plan view for explaining the direction in which the hand push member 120 is positioned when attaching the thick side walls 91A to 91D to the transport cart 3. As shown in FIG. Here, for example, plastic cardboard or the like is used as the thick side walls 91A to 91D.
When attaching thicker side walls 91A to 91D, the pusher members 120 are positioned on the corner members 22 so that the grooves 126a and 126b of the protection portion 124 overlap the truck body 20. Therefore, among the protective parts 124 located at the four corners in a plan view, in the adjacent protective parts 124, the groove part 126a whose groove width is the dimension W1 and the groove part 126b whose groove width is the dimension W1 face each other.
The user can move between the groove 126a of the hand push member 120d and the groove 126b of the hand push member 120a, between the groove 126a of the hand push member 120a and the groove 126b of the hand push member 120b, and between the groove 126a of the hand push member 120b. Each of the side walls 91A to 91D is inserted from above between the groove 126b of the hand push member 120c and between the groove 126a of the hand push member 120c and the groove 126b of the hand push member 120d. Therefore, the thick side walls 91A to 91D are attached to the transport cart 3 by the protective portions 123 of the hand pushing members 120a to 120d.

図１７は、運搬台車３に板厚が薄い側壁９２Ａ～９２Ｄを取り付ける場合に、手押部材１２０を位置決めする向きを説明するための平面図である。ここで、板厚が薄い側壁９２Ａ～９２Ｄとして、例えば木材の合板や単板等が用いられる。
板厚が薄い側壁９２Ａ～９２Ｄを取り付ける場合には、保護部１２４の溝部１２６ｃ、１２６ｄが台車本体部２０と重畳するように手押部材１２０をそれぞれコーナ部材２２に位置決めする。したがって、平面視において４隅に位置する保護部１２４のうち、隣り合う保護部１２４同士では、溝幅が寸法Ｗ２である溝部１２６ｃと溝幅が寸法Ｗ２である溝部１２６ｄとが対向する。
使用者は、手押部材１２０ｄの溝部１２６ｃと手押部材１２０ａの溝部１２６ｄとの間、手押部材１２０ａの溝部１２６ｃと手押部材１２０ｂの溝部１２６ｄとの間、手押部材１２０ｂの溝部１２６ｃと手押部材１２０ｃの溝部１２６ｄとの間、および、手押部材１２０ｃの溝部１２６ｃと手押部材１２０ｄの溝部１２６ｄとの間に、上側から各側壁９２Ａ～９２Ｄを挿入する。したがって、板厚の薄い側壁９２Ａ～９２Ｄは、手押部材１２０ａ～１２０ｄの保護部１２３によって運搬台車３に取り付けられる。 FIG. 17 is a plan view for explaining the direction in which the hand push member 120 is positioned when attaching thin side walls 92A to 92D to the transport cart 3. As shown in FIG. Here, as the thin side walls 92A to 92D, for example, plywood or veneer of wood is used.
When attaching the thin side walls 92A to 92D, the push members 120 are positioned on the corner members 22 so that the grooves 126c and 126d of the protection portion 124 overlap the truck body 20. Therefore, among the protection parts 124 located at the four corners in a plan view, in the adjacent protection parts 124, the groove part 126c whose groove width is the dimension W2 and the groove part 126d whose groove width is the dimension W2 face each other.
The user can move between the groove 126c of the hand push member 120d and the groove 126d of the hand push member 120a, between the groove 126c of the hand push member 120a and the groove 126d of the hand push member 120b, and between the groove 126c of the hand push member 120b. Each side wall 92A to 92D is inserted from above between the groove 126d of the hand push member 120c and between the groove 126c of the hand push member 120c and the groove 126d of the hand push member 120d. Therefore, the thin side walls 92A to 92D are attached to the transport cart 3 by the protective portions 123 of the hand pushing members 120a to 120d.

このように、手押部材１２０の保護部材１２３の溝部１２６ａ～１２６ｄは板厚の異なる側壁を取り付けることができるので、側壁の板厚に合った溝部１２６ａ～１２６ｄに側壁を嵌め込むことで、側壁と溝部１２６ａ～１２６ｄのガタツキを抑制することができる。 In this way, side walls of different thicknesses can be attached to the grooves 126a to 126d of the protection member 123 of the hand push member 120, so by fitting the side walls into the grooves 126a to 126d that match the thickness of the side wall, the side walls can be fixed. This makes it possible to suppress wobbling of the grooves 126a to 126d.
