Description

本発明は、台車等の下面に取り付けられたキャスターの動きを簡単な操作で調節できる台車固定装置に関する。 The present invention relates to a cart fixing device capable of adjusting the movement of a caster attached to the lower surface of a cart or the like by a simple operation.

従来、台車等の下面に取り付けられたキャスターの動きを簡単な操作で調節できる台車用ストッパーが知られている。 2. Description of the Related Art Conventionally, a cart stopper that can adjust the movement of a caster attached to the lower surface of a cart or the like with a simple operation is known.

以下、図６（ａ）、図６（ｂ）を参照しながら従来の台車用ストッパーの構成について説明する。 Hereinafter, the configuration of a conventional cart stopper will be described with reference to FIGS. 6 (a) and 6 (b).

図６（ａ）は、従来の台車用ストッパーの平面図であり、図６（ｂ）は、同台車用ストッパーの側面図である。 FIG. 6A is a plan view of a conventional cart stopper, and FIG. 6B is a side view of the cart stopper.

図６（ａ）、図６（ｂ）に示す通り、従来の台車用ストッパー１０００は、台車の下面１０１０に取り付けられる天板１０２０と、上端側が固定用リング１０２１により天板１０２０に固定された円筒状部材１０３０と、円筒状部材１０３０の中に移動可能に収納されたシャフト部１０４１とその先端に高さ調節可能にネジ込まれた足部１０４２とを有するアジャスター１０４０と、円筒状部材１０３０の外側面に所定の間隔を隔てて互いに平行に配置され固定された一対の平行支持板１０３１に対して第１連結ピン１０５１により一端部１０５０ａが回動可能に連結され、アジャスター１０４０のシャフト部１０４１に対して第２連結ピン１０５２により連結され、他端部１０５０ｂにおいて作業者が踏み込む際に靴底面に当たる第１プレート１０５３が取り付けられた第１ペダル１０５０と、第１ペダル１０５０の内部空間１０５４に配置され、第１ペダル１０５０にサブ連結ピン１０６１により連結され、一端部１０６０ａが円筒状部材１０３０の外側面に形成された段差部１０３２に対して係合可能なロック用ペダル１０６０とから構成されている。ロック用ペダル１０６０の他端部１０６０ｂにはサブプレート１０６３が取り付けられている。 As shown in FIGS. 6A and 6B, a conventional cart stopper 1000 includes a top plate 1020 attached to the lower surface 1010 of the cart, and a cylinder whose upper end is fixed to the top plate 1020 by a fixing ring 1021. An adjuster 1040 having a shaft-like member 1030, a shaft portion 1041 movably housed in the cylindrical member 1030, and a foot portion 1042 screwed to the tip thereof so as to be adjustable in height, and an outside of the cylindrical member 1030 One end portion 1050a is rotatably connected by a first connecting pin 1051 to a pair of parallel support plates 1031 arranged and fixed in parallel to each other at a predetermined interval on the side surface, and to the shaft portion 1041 of the adjuster 1040. The first connecting pin 1052 that contacts the bottom of the shoe when the operator steps on the other end 1050b. The first pedal 1050 to which the first pedal 1050 is attached and the inner space 1054 of the first pedal 1050 are connected to the first pedal 1050 by the sub-connecting pin 1061, and one end portion 1060 a is formed on the outer surface of the cylindrical member 1030. It is comprised from the locking pedal 1060 which can be engaged with the step part 1032 made. A sub plate 1063 is attached to the other end portion 1060 b of the locking pedal 1060.

また、円筒状部材１０３０の外側面には、第２連結ピン１０５２が上下方向に移動出来るようにするための案内用長孔１０３３が形成されている。また、第１ペダル１０５０は、第１連結ピン１０５１に取り付けられた第１圧縮バネ１０５５により、第１プレート１０５３が常に台車の下面１０１０側に向けて回動する方向に付勢されており、ロック用ペダル１０６０は、サブ連結ピン１０６１に取り付けられたサブ圧縮バネ１０６２により、サブプレート１０６３が常に台車の下面１０１０側に向けて回動する方向に付勢されている。 A long guide hole 1033 is formed on the outer surface of the cylindrical member 1030 so that the second connecting pin 1052 can move in the vertical direction. The first pedal 1050 is urged by a first compression spring 1055 attached to the first connecting pin 1051 in a direction in which the first plate 1053 is always rotated toward the lower surface 1010 side of the carriage. The pedal 1060 is urged by a sub compression spring 1062 attached to the sub connecting pin 1061 in a direction in which the sub plate 1063 is always rotated toward the lower surface 1010 side of the carriage.

上記構成のもとで、次に、従来の台車用ストッパー１０００の動作について説明する。 Next, the operation of the conventional cart stopper 1000 will be described.

作業者が第１ペダル１０５０の第１プレート１０５３を靴底面で踏み込むことにより、ロック用ペダル１０６０は第１ペダル１０５０の内部空間１０５４に位置したまま矢印Ｄ方向に回動する（図６（ｂ）参照）。 When the operator steps on the first plate 1053 of the first pedal 1050 with the bottom of the shoe, the locking pedal 1060 rotates in the arrow D direction while being positioned in the internal space 1054 of the first pedal 1050 (FIG. 6B). reference).

具体的には、第１ペダル１０５０の矢印Ｄ方向への回動に伴って、ロック用ペダル１０６０の一端部１０６０ａは、サブ圧縮バネ１０６２による付勢力により円筒状部材１０３０の外側面に当接しながら下方にスライドして行き、最終的に段差部１０３２に対して係合する。この時、サブプレート１０６３は、側面視で、第１ペダル１０５０の内部空間１０５４から少し上方に飛び出した状態になる。 Specifically, as the first pedal 1050 rotates in the direction of arrow D, the one end portion 1060a of the locking pedal 1060 is in contact with the outer surface of the cylindrical member 1030 by the urging force of the sub compression spring 1062. It slides downward and finally engages with the stepped portion 1032. At this time, the sub plate 1063 protrudes slightly upward from the internal space 1054 of the first pedal 1050 in a side view.

上記動作に伴って、シャフト部１０４１が円筒状部材１０３０の内部を下方に移動し、円筒状部材１０３０から最も出た状態となり（図６（ｂ）のＨｍａｘ参照）、台車の下面１０１０に設けられたキャスター（図示省略）が床面１０７０から浮いた状態となるので、台車はキャスターによる移動が出来なくなり、床面１０７０に固定された状態となる。 Along with the above operation, the shaft portion 1041 moves downward inside the cylindrical member 1030 and comes out of the cylindrical member 1030 (see Hmax in FIG. 6B), and is provided on the lower surface 1010 of the carriage. Since the caster (not shown) floats from the floor surface 1070, the carriage cannot be moved by the caster and is fixed to the floor surface 1070.

一方、台車の床面１０７０への上記固定状態を解除するためには、側面視で、第１ペダル１０５０の内部空間１０５４から少し上方に飛び出した状態にあるサブプレート１０６３を靴底面で踏み込むことにより、ロック用ペダル１０６０の一端部１０６０ａが、図６（ｂ）の図中において反時計方向に回動して、段差部１０３２との係合が外れるので、第１ペダル１０５０は、第１圧縮バネ１０５５の付勢力により図６（ｂ）の図中において時計方向に回動し、それに伴って上方へ移動するロック用ペダル１０６０の一端部１０６０ａが円筒状部材１０３０を天板１０２０に固定するための固定用リング１０２１の下面に当接した位置で、時計方向への上記回動が停止される。 On the other hand, in order to release the above-described fixed state to the floor surface 1070 of the carriage, the sub-plate 1063 in a state of protruding slightly upward from the internal space 1054 of the first pedal 1050 in a side view is stepped on the shoe bottom surface. Since the one end portion 1060a of the locking pedal 1060 rotates counterclockwise in the drawing of FIG. 6B and disengages from the step portion 1032, the first pedal 1050 is a first compression spring. The one end portion 1060a of the locking pedal 1060 that rotates in the clockwise direction in the drawing of FIG. 6B by the urging force of 1055 and moves upward in accordance therewith is for fixing the cylindrical member 1030 to the top plate 1020. The rotation in the clockwise direction is stopped at the position in contact with the lower surface of the fixing ring 1021.

上記動作に伴って、シャフト部１０４１が円筒状部材１０３０の内部を上方に移動し、円筒状部材１０３０の中に最も入った状態となり（図６（ｂ）のＨｍｉｎ参照）、台車の下面１０１０に設けられたキャスター（図示省略）が床面１０７０に接触した状態となるので、台車はキャスターによる移動が可能となる。ここで、キャスターの接地面と台車の下面１０１０との距離は、Ｈｍｉｎより大きく、且つ、Ｈｍａｘより小さいものとする。 Along with the above operation, the shaft portion 1041 moves upward in the cylindrical member 1030 and enters the cylindrical member 1030 most (see Hmin in FIG. 6B). Since the casters (not shown) provided are in contact with the floor surface 1070, the carriage can be moved by the casters. Here, it is assumed that the distance between the contact surface of the caster and the lower surface 1010 of the carriage is larger than Hmin and smaller than Hmax.

これにより、足で台車用ストッパー１０００の第１ペダル１０５０を踏み込むという簡単な操作により、キャスターを床面１０７０から浮かすことが出来て台車を床面１０７０に固定可能とし、また、サブペダル１０６０を踏み込むという簡単な操作により、キャスターを床面１０７０に接地させて台車を移動可能とするものである。 Accordingly, the caster can be lifted from the floor surface 1070 by a simple operation of depressing the first pedal 1050 of the cart stopper 1000 with the foot, the cart can be fixed to the floor surface 1070, and the sub pedal 1060 is depressed. By simple operation, the caster is brought into contact with the floor surface 1070 so that the carriage can be moved.

尚、上述した従来の台車用ストッパー１０００の足部１０４２の台車の下面１０１０からの距離の一例としては、Ｈｍａｘ＝１５０ｍｍ、Ｈｍｉｎ＝１２０ｍｍである。 In addition, as an example of the distance from the lower surface 1010 of the trolley of the foot 1042 of the conventional trolley stopper 1000 described above, Hmax = 150 mm and Hmin = 120 mm.

しかしながら、この様な従来の台車用ストッパー１０００の構成では、台車をキャスターで移動させるときに、台車の下面１０１０から下方に向けて突き出た足部１０４２が、床面１０７０の段差や凹凸部に引っかかるという問題があった。 However, in such a configuration of the conventional cart stopper 1000, when the cart is moved by a caster, the foot portion 1042 protruding downward from the bottom surface 1010 of the cart is caught by the step or uneven portion of the floor surface 1070. There was a problem.

本発明の目的は、従来のこの様な台車用ストッパーの課題に鑑みて、台車の下面からの出っ張り部分の寸法を従来に比べて小さくした台車固定装置を提供することを目的とする。 An object of the present invention is to provide a cart fixing device in which the size of the protruding portion from the lower surface of the cart is smaller than that of the conventional cart in view of the problem of the conventional cart stopper.

And a locking pedal 160 that can be engaged with the first stepped portion 132 formed on the outer surface of the cylindrical holding member 130. It has been. A sub plate 163 is attached to the other end 160 b of the locking pedal 160.

尚、図１（ｂ）では、踏み込まれた状態における第１ペダル１５０及びそれに連動して下方に移動したロック用ペダル１６０を実線で描いたが、図面を見易くするために、第１ペダル１５０を構成する一対の平行な板状部材の内、図１（ａ）中において上側に配置されている板状部材を実線で描いた。これにより、第１ペダル１５０を構成する一対の平行な板状部材の間に挟まれたロック用ペダル１６０等の外形は実線で描いた。 In FIG. 1 (b), the first pedal 150 in the depressed state and the locking pedal 160 that moves downward in conjunction with the first pedal 150 are drawn with solid lines. Of the pair of parallel plate-like members to be configured, the plate-like member arranged on the upper side in FIG. 1A is drawn with a solid line. Thus, the outer shape of the locking pedal 160 and the like sandwiched between a pair of parallel plate-like members constituting the first pedal 150 is drawn with a solid line.

ここで、円筒状保持部材１３０は、その上端に固定された一対の連結板１３４が保持部材連結ピン１３６により第１支持板１２１に回動可能に連結されており、且つ、その上端に固定された第１係合部１３５の先端部１３５ａが第１ロック部材１２２の第２段差部１２２ａと係合して、通常は、図１（ａ）、図１（ｂ）に示す通り、その上端側が天板１２０に接触した状態が保持される構成である。尚、第１ロック部材１２２は、第１ロック部材用連結ピン１２３を回動中心として、第１ロック部材用圧縮バネ１２４により、図１（ｂ）中において時計方向に回動する様に常に付勢されている。 Here, the cylindrical holding member 130 has a pair of connecting plates 134 fixed to its upper end rotatably connected to the first support plate 121 by holding member connecting pins 136, and is fixed to its upper end. The front end portion 135a of the first engaging portion 135 is engaged with the second stepped portion 122a of the first locking member 122, and usually the upper end side thereof is as shown in FIGS. 1 (a) and 1 (b). In this configuration, the state in contact with the top plate 120 is maintained. The first lock member 122 is always attached so as to rotate clockwise in FIG. 1B by the first lock member compression spring 124 with the first lock member connecting pin 123 as the rotation center. It is energized.

また、円筒状保持部材１３０の外側面には、円筒状保持部材１３０を貫通するアジャスター連結ピン１５２が上下方向に移動出来るようにするための案内用長孔１３３が形成されている。また、第１ペダル１５０は、第１連結ピン１５１に取り付けられた第１圧縮バネ１５５により、第１プレート１５３が常に台車の下面１１０側に向けて回動する方向に付勢されており、ロック用ペダル１６０は、サブ連結ピン１６１に取り付けられたサブ圧縮バネ１６２により、サブプレート１６３が常に台車の下面１１０側に向けて回動する方向に付勢されている。 In addition, an elongated guide hole 133 is formed on the outer surface of the cylindrical holding member 130 so that the adjuster connecting pin 152 penetrating the cylindrical holding member 130 can move in the vertical direction. The first pedal 150 is urged by a first compression spring 155 attached to the first connecting pin 151 in a direction in which the first plate 153 is always rotated toward the lower surface 110 side of the carriage. The pedal 160 is urged by a sub compression spring 162 attached to the sub connection pin 161 in a direction in which the sub plate 163 is always rotated toward the lower surface 110 side of the carriage.

更に、台車固定装置１００は、第２ペダル１７０を備え、その第２ペダル１７０は、第１支持板１２１に対して第２連結ピン１７１を回動中心として回動可能に連結された上面視で略「コ」の字状（図１（ａ）参照）の一方端１７０ａに側面視で略「ヘ」の字状（図１（ｂ）参照）の第２プレート１７２を有し、その第２プレート１７２が踏み込まれることで他方端１７０ｂ（上面視で略「コ」の字状の中央の一辺に相当する部分）が第１ロック部材１２２に当たり矢印Ａ方向（図１（ｂ）参照）に回動させることで第１係合部１３５の先端部１３５ａと第１ロック部材１２２の第２段差部１２２ａとの係合を解除する様に構成されている。 Further, the cart fixing device 100 includes a second pedal 170, and the second pedal 170 is connected to the first support plate 121 so as to be rotatable about the second connecting pin 171 as a center of rotation. A second plate 172 having a substantially “f” shape (see FIG. 1B) in a side view is provided at one end 170a of a substantially “U” shape (see FIG. 1A). When the plate 172 is stepped on, the other end 170b (a portion corresponding to one side of the center of the substantially “U” shape in a top view) hits the first lock member 122 and rotates in the direction of arrow A (see FIG. 1B). By being moved, the engagement between the distal end portion 135a of the first engaging portion 135 and the second stepped portion 122a of the first locking member 122 is configured to be released.

尚、図１（ｂ）では、第２ペダル１７０の外形線は、本来ならば実線で描くべきであるが、ここでは、図面を見易くするために、第２ペダル１７０の第２プレート１７２及びその近傍のみを実線で描き、それ以外の部分は二点鎖線で描いた。 In FIG. 1B, the outline of the second pedal 170 should be drawn with a solid line, but here, in order to make the drawing easier to see, the second plate 172 of the second pedal 170 and its Only the vicinity is drawn with a solid line, and the other parts are drawn with a two-dot chain line.

また、台車固定装置１００は、一対の保持部材跳ね上げ用引っ張りバネ１８０を備え、その一対の保持部材跳ね上げ用引っ張りバネ１８０の各一端１８０ａは、円筒状保持部材１３０の下端側の両側面にそれぞれ立設された一対の第１立設ピン１３７にそれぞれ連結され、各他端１８０ｂは、第２ペダル１７０の上端側の両側面にそれぞれ立設された一対の第２立設ピン１７３にそれぞれ連結されている。 Further, the cart fixing device 100 includes a pair of holding member jumping tension springs 180, and one ends 180 a of the pair of holding member jumping tension springs 180 are provided on both side surfaces on the lower end side of the cylindrical holding member 130. Each of the other ends 180b is connected to a pair of second standing pins 173 respectively standing on both side surfaces on the upper end side of the second pedal 170. It is connected.

また、図１（ｂ）に示す通り、第１ペダル１５０が二点鎖線で示された位置にある状態において、第２プレート１７２が下方に踏み込まれる前の時点では、保持部材跳ね上げ用引っ張りバネ１８０の一端１８０ａが連結された第１立設ピン１３７の中心軸と保持部材連結ピン１３６の中心軸とを結ぶ仮想ラインＶＬを基準として、保持部材跳ね上げ用引っ張りバネ１８０の他端１８０ｂが連結された第２立設ピン１７３は、図１（ｂ）中において右側に存在する様に構成されている。 In addition, as shown in FIG. 1B, in the state where the first pedal 150 is in the position indicated by the two-dot chain line, the holding member spring-up tension spring before the second plate 172 is stepped down. The other end 180b of the holding member spring-up tension spring 180 is connected with reference to a virtual line VL connecting the center axis of the first standing pin 137 to which the one end 180a of 180 is connected and the center axis of the holding member connecting pin 136. The second upright pins 173 thus formed are configured to exist on the right side in FIG.

この場合、図３に示す通り、第１立設ピン１３７には、保持部材跳ね上げ用引っ張りバネ１８０による引っ張り力Ｆが作用している。ここで、仮想ラインＶＬをＹ軸とし、それに直交する軸をＸ軸として、その引っ張り力Ｆをベクトル成分に分解して考えると、Ｘ軸の正方向に向かう成分の力Ｆｘと、Ｙ軸の正方向に向かう成分の力Ｆｙに分解できる。そして、Ｘ軸方向成分の力Ｆｘは、円筒状保持部材１３０に対して保持部材連結ピン１３６を回動中心としてＸ軸の正方向に回動させようと作用するが、円筒状保持部材１３０の上端縁部１３０ａが天板１２０に接触しているので、円筒状保持部材１３０は天板１２０に直交した状態を維持したまま動かない。また、この場合、第２ペダル１７０の他方端１７０ｂは第１ロック部材１２２から下方に離れて位置している。 In this case, as shown in FIG. 3, a tensile force F is applied to the first standing pin 137 by the holding member spring-up tension spring 180. Here, assuming that the virtual line VL is the Y axis and the axis orthogonal to the X axis is the X axis, and the tensile force F is decomposed into vector components, the component force Fx toward the positive direction of the X axis and the Y axis It can be decomposed into a component force Fy that goes in the positive direction. The force Fx of the X-axis direction component acts to rotate the cylindrical holding member 130 in the positive direction of the X axis around the holding member connecting pin 136 as a rotation center. Since the upper edge 130 a is in contact with the top plate 120, the cylindrical holding member 130 does not move while maintaining a state orthogonal to the top plate 120. In this case, the other end 170 b of the second pedal 170 is positioned away from the first lock member 122.

ここで、図３は、保持部材跳ね上げ用引っ張りバネ１８０による引っ張り力Ｆをベクトル成分に分解した説明図である。 Here, FIG. 3 is an explanatory diagram in which the tensile force F generated by the holding member spring-up tension spring 180 is decomposed into vector components.

これに対して、第１ペダル１５０が二点鎖線で示された位置にある状態において（図１（ｂ）参照）、第２プレート１７２が下方に踏み込まれると、図２に示す通り、他方端１７０ｂが第２連結ピン１７１を回動中心として矢印Ｂ方向に上昇して、第１ロック部材１２２の下面に当たることで第１ロック部材１２２を矢印Ａ方向に回動させるので、第１係合部１３５の先端部１３５ａとの係合が外れる構成である。 On the other hand, when the second plate 172 is stepped downward in the state where the first pedal 150 is in the position indicated by the two-dot chain line (see FIG. 1B), the other end as shown in FIG. Since the first locking member 122 is rotated in the direction of arrow A by 170b ascending about the second connecting pin 171 in the direction of arrow B and hitting the lower surface of the first locking member 122, the first engaging portion This is a configuration in which the engagement with the front end portion 135a of 135 is disengaged.

ここで、図２は、第２プレート１７２が下方に踏み込まれた場合の状態を説明するための、一部断面を含む側面図である。 Here, FIG. 2 is a side view including a partial cross-section for explaining a state when the second plate 172 is stepped down.

一方、第２プレート１７２が下方に踏み込まれるにつれて、保持部材跳ね上げ用引っ張りバネ１８０の他端１８０ｂが連結された第２立設ピン１７３は、第２連結ピン１７１を回動中心として、図１（ｂ）中において反時計方向に回動し、仮想ラインＶＬを基準として図３に示すＸ軸の負方向の領域（図３において、仮想ラインＶＬを基準として第２立設ピン１７３が存在する領域と反対側の領域）に移動する様に構成されている。 On the other hand, as the second plate 172 is stepped downward, the second standing pin 173 to which the other end 180b of the holding member spring-up tension spring 180 is connected is centered on the second connecting pin 171 as shown in FIG. 3B, the X-axis negative direction region shown in FIG. 3 is rotated with reference to the virtual line VL (the second upright pin 173 is present with reference to the virtual line VL in FIG. 3). It is configured to move to a region opposite to the region.

そうすると、保持部材跳ね上げ用引っ張りバネ１８０による引っ張り力Ｆは、Ｘ軸の負方向に向かう成分を有することになり、そのＸ軸の負方向に向かう成分の力が、円筒状保持部材１３０に対して保持部材連結ピン１３６を回動中心としてＸ軸の負方向に回動させようと作用する。 Then, the tensile force F generated by the holding member spring-up tension spring 180 has a component in the negative direction of the X axis, and the force of the component in the negative direction of the X axis is applied to the cylindrical holding member 130. Thus, the holding member connecting pin 136 acts as a rotation center to rotate in the negative direction of the X axis.

この場合、上述した通り、既に、第１係合部１３５の先端部１３５ａと第１ロック部材１２２との係合は外れているので、図２に示す通り、上記Ｘ軸の負方向への回動作用によって、円筒状保持部材１３０は、保持部材連結ピン１３６を回動中心として、矢印Ｃ方向に回動する構成である。 In this case, as described above, since the engagement between the distal end portion 135a of the first engagement portion 135 and the first lock member 122 has already been released, as shown in FIG. 2, the rotation of the X axis in the negative direction is performed. For operation, the cylindrical holding member 130 is configured to rotate in the direction of the arrow C with the holding member connecting pin 136 as a rotation center.

上記構成により、図２に示す通り、台車固定部材１００の一端部１５０ａ側の最下端部１５６と台車の下面１１０との距離Ｈｓ（具体的には、一例として１００ｍｍ）は、図１（ｂ）に示した、シャフト部１４１が円筒状保持部材１３０の内部に最も挿入された状態における台車の下面１１０からの足部１４２の出っ張り距離Ｈｍｉｎ（具体的には、一例として１２０ｍｍ）より更に小さくなる。これにより、台車固定装置１００の台車の下面１１０からの床面１０７０方向への出っ張り部分の寸法を従来に比べて小さく出来る。 With the above configuration, as shown in FIG. 2, the distance Hs (specifically, 100 mm as an example) between the lowermost end 156 on the one end 150a side of the carriage fixing member 100 and the lower surface 110 of the carriage is shown in FIG. The protruding distance Hmin (specifically, 120 mm as an example) of the foot 142 from the lower surface 110 of the carriage in the state where the shaft portion 141 is inserted into the cylindrical holding member 130 as shown in FIG. Thereby, the dimension of the protrusion part from the lower surface 110 of the trolley | bogie of the trolley | bogie fixing device 100 to the floor surface 1070 direction can be made small compared with the past.

This corresponds to that indicated by the two-dot chain line in b). 5 is a perspective view showing the cart fixing device 100 in a state where the cylindrical holding member 130 is flipped up in a state where a caster (not shown) of the cart is in contact with the floor surface 1070. Corresponds to

尚、図５では、ロック用ペダル１６０のサブプレート１６３が、第１ペダル１５０の内部空間１５４から上方に突き出している点で、図１（ｂ）に示した、サブプレート１６３が第１ペダル１５０の内部空間１５４内に納まっている構成と相違するが、何れの構成も本発明の一実施の形態に含まれる。 In FIG. 5, the sub plate 163 of the locking pedal 160 protrudes upward from the internal space 154 of the first pedal 150, so that the sub plate 163 shown in FIG. Although the configuration is different from the configuration stored in the internal space 154, any configuration is included in one embodiment of the present invention.

１）台車を床面に固定する動作：
作業者は、台車を床面１０７０に固定するために、図４に示す状態にある台車固定装置１００の第１ペダル１５０の第１プレート１５３を下方に向けて踏み込む。 1) Operation to fix the cart to the floor:
The operator steps down the first plate 153 of the first pedal 150 of the carriage fixing device 100 in the state shown in FIG. 4 in order to fix the carriage to the floor surface 1070.

これにより、図１（ｂ）に示す通り、矢印Ｄ方向に第１ペダル１５０が回動するとともに、ロック用ペダル１６０の一端部１６０ａが円筒状保持部材１３０の外側面に沿って下降し、第１段差部１３２と係合することで、作業者が第１ペダル１５０から足を離しても、第１ペダル１５０は下降した状態でロックされる。この下降動作と同時に、アジャスター１４０が円筒状保持部材１３０の中を下方にスライド移動して最も出っ張った状態（図１（ｂ）のＨｍａｘ参照）となって、第１ペダル１５０がロックされるので、キャスター（図示省略）は床面１０７０から浮いた状態となり、台車はキャスターによる移動が出来なくなり、床面１０７０に固定された状態となる。ここで、キャスターの接地面と台車の下面１１０との距離は、Ｈｍｉｎより大きく、且つ、Ｈｍａｘより小さいものとする。 As a result, as shown in FIG. 1B, the first pedal 150 rotates in the direction of the arrow D, and the one end 160a of the locking pedal 160 descends along the outer surface of the cylindrical holding member 130. By engaging with the one step portion 132, even if the operator removes his / her foot from the first pedal 150, the first pedal 150 is locked in a lowered state. At the same time as the lowering operation, the adjuster 140 slides downward in the cylindrical holding member 130 to the most protruding state (see Hmax in FIG. 1B), and the first pedal 150 is locked. The caster (not shown) floats from the floor surface 1070, and the carriage cannot move by the caster and is fixed to the floor surface 1070. Here, it is assumed that the distance between the contact surface of the caster and the lower surface 110 of the carriage is larger than Hmin and smaller than Hmax.

２）台車のキャスターを床面に接地させる動作：
次に、作業者は、台車のキャスター（図示省略）を床面１０７０に接地させるために、第１ペダル１５０の内部空間１５４から側面視で上方に飛び出した状態にあるロック用ペダル１６０のサブプレート１６３を踏み込む。 2) Action to ground the dolly caster to the floor:
Next, in order to ground the caster caster (not shown) to the floor surface 1070, the operator projects the sub plate of the locking pedal 160 in a state of protruding upward from the inner space 154 of the first pedal 150 in a side view. Step 163.

これにより、ロック用ペダル１６０の一端部１６０ａが、図１（ｂ）に示す通り、矢印Ｅ方向に回動して、円筒状保持部材１３０の第１段差部１３２との係合が外れロックが解除されるので、第１ペダル１５０と共にアジャスター１４０が円筒状保持部材１３０の中を上方に向けてスライド移動して、最も入り込んだ状態となる（図１（ｂ）のＨｍｉｎ参照）。 As a result, the one end 160a of the locking pedal 160 is rotated in the direction of arrow E as shown in FIG. 1B, and the engagement with the first step portion 132 of the cylindrical holding member 130 is released and the lock is released. Since the release is released, the adjuster 140 slides upward in the cylindrical holding member 130 together with the first pedal 150, and is in the most inserted state (see Hmin in FIG. 1B).

これにより、台車の下面１０１０に設けられたキャスター（図示省略）が床面１０７０に接触した状態となるので、台車はキャスターによる移動が可能となる。 As a result, since the casters (not shown) provided on the lower surface 1010 of the cart are in contact with the floor surface 1070, the cart can be moved by the casters.

３）円筒状保持部材１３０を跳ね上げる動作：
次に、作業者は、本実施の形態の台車固定装置１００の台車の下面１１０からの出っ張り寸法を更に小さくするために、第２ペダル１７０の第２プレート１７２を踏み込む。 3) The operation of jumping up the cylindrical holding member 130:
Next, the operator steps on the second plate 172 of the second pedal 170 in order to further reduce the protruding dimension from the lower surface 110 of the cart of the cart fixing device 100 of the present embodiment.

これにより、図２に示す通り、他方端１７０ｂが第２連結ピン１７１を回動中心として矢印Ｂ方向に上昇して、第１ロック部材１２２の下面に当たることで第１ロック部材１２２を矢印Ａ方向に回動させるので、第１係合部１３５の先端部１３５ａとの係合が外れる。 As a result, as shown in FIG. 2, the other end 170 b rises in the arrow B direction with the second connecting pin 171 as the center of rotation and hits the lower surface of the first lock member 122, so Therefore, the engagement of the first engagement portion 135 with the distal end portion 135a is released.

一方、上記踏み込み動作に伴って、保持部材跳ね上げ用引っ張りバネ１８０の他端１８０ｂが連結された第２立設ピン１７３は、第２連結ピン１７１を回動中心として、図１（ｂ）中において反時計方向に回動し、仮想ラインＶＬを基準として図３に示すＸ軸の負方向の領域に移動する。そのため、保持部材跳ね上げ用引っ張りバネ１８０による引っ張り力Ｆは、Ｘ軸の負方向に向かう成分を有することになり、そのＸ軸の負方向に向かう成分の力が、第１係合部１３５の先端部１３５ａでの係合が外れて回動可能になっている円筒状保持部材１３０に対して保持部材連結ピン１３６を回動中心として作用し、円筒状保持部材１３０は矢印Ｃ方向に大きく回動し、図２に示す通り、連結板１３４の切欠部１３４ａが、天板１２０の角部１２０ａに当たって、その回動は停止する（図５参照）。 On the other hand, the second standing pin 173 to which the other end 180b of the holding member spring-up tension spring 180 is connected in accordance with the stepping-in operation is shown in FIG. 1B with the second connection pin 171 as the rotation center. 3 to the counterclockwise direction and move to the negative X-axis region shown in FIG. 3 with reference to the virtual line VL. For this reason, the pulling force F by the holding member spring-up tension spring 180 has a component toward the negative direction of the X axis, and the force of the component toward the negative direction of the X axis is the force of the first engaging portion 135. The holding member coupling pin 136 acts on the cylindrical holding member 130 which is disengaged at the distal end portion 135a and is rotatable, and the cylindrical holding member 130 is rotated in the direction of arrow C. As shown in FIG. 2, the notch part 134a of the connecting plate 134 hits the corner part 120a of the top plate 120, and the rotation stops (see FIG. 5).

これにより、図２に示す通り、台車固定部材１００の一端部１５０ａ側の最下端部１５６と台車の下面１１０との距離Ｈｓ（具体的には、一例として１００ｍｍ）は、図１（ｂ）に示した、シャフト部１４１が円筒状保持部材１３０の内部に最も挿入された状態における台車の下面１１０からの足部１４２の出っ張り距離Ｈｍｉｎ（具体的には、一例として１２０ｍｍ）より更に小さくなる。 Thereby, as shown in FIG. 2, the distance Hs (specifically, 100 mm as an example) between the lowermost end 156 on the one end 150a side of the carriage fixing member 100 and the lower surface 110 of the carriage is shown in FIG. The protruding distance Hmin (specifically, 120 mm as an example) of the foot portion 142 from the lower surface 110 of the carriage in the state where the shaft portion 141 is most inserted into the cylindrical holding member 130 is shown.

よって、台車をキャスターで移動させるときに、台車の下面１１０から下方に向けて最も突き出た部分（図２の最下端部１５６参照）が、床面１０７０の段差や凹凸部に引っかかることが従来に比べて低減される。 Therefore, when the carriage is moved by a caster, the portion that protrudes most downward from the lower surface 110 of the carriage (see the lowest end portion 156 in FIG. 2) has hitherto been caught by a step or uneven portion of the floor surface 1070. It is reduced compared.

４）円筒状保持部材１３０を跳ね上げた状態からものと状態に戻す動作：
次に、作業者は、円筒状保持部材１３０を跳ね上げた状態からものと状態に戻すために、第２ペダル１７０の第２プレート１７２を矢印Ｇ方向（図２参照）に回動させる。 4) Operation to return the cylindrical holding member 130 from the state in which it is flipped up to the state:
Next, the operator rotates the second plate 172 of the second pedal 170 in the direction of arrow G (see FIG. 2) in order to return the cylindrical holding member 130 from the state of being flipped up.

これにより、第２立設ピン１７３は、第２連結ピン１７１を回動中心として、図２中において時計方向に回動し、第１立設ピン１３７の中心軸と保持部材連結ピン１３６の中心軸とを結ぶ仮想ラインＶＬ（図２参照）を基準としてＸ軸の正方向の領域に移動する。そのため、保持部材跳ね上げ用引っ張りバネ１８０による引っ張り力Ｆは、Ｘ軸の正方向に向かう成分を有することになり、そのＸ軸の正方向に向かう成分の力が、円筒状保持部材１３０に対して保持部材連結ピン１３６を回動中心として作用し、円筒状保持部材１３０は矢印Ｃ方向と反対方向に大きく回動し、図１（ｂ）に示す通り、円筒状保持部材１３０の上端縁部１３０ａが、天板１２０に当たって、その回動は停止する。それと同時に、第１係合部１３５の先端部１３５ａが第１ロック部材１２２の第２段差部１２２ａと係合することにより、円筒状保持部材１３０は天板１２０に対して立設した状態で固定される（図４参照）。 As a result, the second upright pin 173 rotates around the second connecting pin 171 in the clockwise direction in FIG. 2, and the central axis of the first upright pin 137 and the center of the holding member connecting pin 136 are rotated. It moves to the area | region of the positive direction of an X-axis on the basis of the virtual line VL (refer FIG. 2) which connects an axis | shaft. Therefore, the tensile force F generated by the holding member spring-up tension spring 180 has a component in the positive direction of the X axis, and the force of the component in the positive direction of the X axis is applied to the cylindrical holding member 130. The holding member connecting pin 136 acts as a rotation center, and the cylindrical holding member 130 rotates greatly in the direction opposite to the arrow C direction, and as shown in FIG. 1B, the upper end edge of the cylindrical holding member 130 When 130a hits the top plate 120, the rotation stops. At the same time, the distal end portion 135a of the first engaging portion 135 engages with the second stepped portion 122a of the first locking member 122, so that the cylindrical holding member 130 is fixed in a standing state with respect to the top plate 120. (See FIG. 4).
