第2進退部52は、本体部60、上側係止部62、及び2つの第2円環部材63を含む。本体部60のXY平面での断面形状は、第2貫通孔54のXY平面での断面形状よりも僅かに小さく、その断面形状に対応する矩形状になっている。本体部60の下側端部は、高さ方向延在部50の長さに拘わらず第2貫通孔54に収容され、本体部60において第2貫通孔54に収容される部分は、高さ方向延在部50の高さ低くなるにしたがって大きくなる。 The second advancing / retreating portion 52 includes a main body portion 60, an upper locking portion 62, and two second ring members 63. The cross-sectional shape of the main body 60 on the XY plane is slightly smaller than the cross-sectional shape of the second through hole 54 on the XY plane, and has a rectangular shape corresponding to the cross-sectional shape. The lower end of the main body 60 is housed in the second through hole 54 regardless of the length of the extending portion 50 in the height direction, and the portion of the main body 60 housed in the second through hole 54 is high. The height of the directional extending portion 50 increases as the height decreases.

上側係止部62は、本体部60の上側に設けられる。本体部60の上側端部には、Y方向に延在する丸棒状部分68が設けられる。丸棒状部分68の長さは、本体部60の幅(Y方向長さ)よりも長く、丸棒状部分68は、本体部60のY方向両側で本体部60からY方向外方に突出する突出部69を有する。突出部69は、丸棒状部分68における突出部以外の他部分よりも外径が小さい丸棒形状を有し、突出部69の中心軸は、その他部分の中心軸と同一直線上に位置する。 The upper locking portion 62 is provided on the upper side of the main body portion 60. A round bar-shaped portion 68 extending in the Y direction is provided at the upper end portion of the main body portion 60. The length of the round bar-shaped portion 68 is longer than the width of the main body portion 60 (length in the Y direction), and the round bar-shaped portion 68 projects outward from the main body portion 60 on both sides of the main body portion 60 in the Y direction. It has a part 69. The protruding portion 69 has a round bar shape having a smaller outer diameter than other portions other than the protruding portion in the round bar-shaped portion 68, and the central axis of the protruding portion 69 is located on the same straight line as the central axis of the other portion.

第2円環部材63は、例えば、冷やし嵌め、焼き嵌め、又は圧入により突出部69の外周面に取り付けられる。第2円環部材63は、静止摩擦力よりも大きい力が加わると突出部69の中心軸を支点として回動する。突出部69の中心軸は、第2支点を構成する。なお、第2円環部材63を、上記他部分のY方向端面に当接するまで突出部69にY方向に嵌め込み、その後、図示しない止め輪を、突出部69のY方向先端部に取り付けてもよく、この場合、第2円環部材63の離脱を抑制できて好ましい。 The second annular member 63 is attached to the outer peripheral surface of the protrusion 69 by, for example, cold fitting, shrink fitting, or press fitting. When a force larger than the static friction force is applied, the second annular member 63 rotates around the central axis of the protruding portion 69 as a fulcrum. The central axis of the protrusion 69 constitutes the second fulcrum. The second annular member 63 may be fitted into the protruding portion 69 in the Y direction until it abuts on the Y-direction end surface of the other portion, and then a retaining ring (not shown) may be attached to the Y-direction tip portion of the protruding portion 69. Often, in this case, the detachment of the second ring member 63 can be suppressed, which is preferable.

上側係止部62は、板形状を有し、略矩形状の上側係止面70を含む。上側係止部62は、金属又は樹脂製の本体部71と、ゴム製の係止面被覆部72を含む。本体部71は、略直方体の形状を有し、係止面被覆部72は、本体部47の上面に接着剤等で固定される。係止面被覆部72の上面が上側係止面70を構成する。 The upper locking portion 62 has a plate shape and includes a substantially rectangular upper locking surface 70.

The main body 71 has a substantially rectangular parallelepiped shape, and the locking surface covering portion 72 is fixed to the upper surface of the main body 47 with an adhesive or the like. The upper surface of the locking surface covering portion 72 constitutes the upper locking surface 70.

台車1は、更に、連結部材80と、スプロケット81を備える。連結部材は、例えば、無限軌道(キャタピラー(登録商標))の一部で構成され、非環状のチェーンで構成される。より詳しくは、連結部材80は、例えば、金属製のピース(リンク)88を多数連結した履帯で構成される。連結部材80の一方側端部は、第1進退部22のX方向後側端部に接続され、連結部材80の他方側端部は、第2進退部52の下側端部に接続される。連結部材80は、第1貫通孔24と第2貫通孔54の接続部を跨ぐように、第1貫通孔24の一部と第2貫通孔54の一部に収容される。円弧状延在孔部24bの下側には、摩擦力が小さい材料、例えば樹脂材で構成されたガイド部82が設けられる。連結部材80の延在方向の一部は、そのガイド部82に案内されるように円弧状延在孔部24b内を移動する。 The carriage 1 further includes a connecting member 80 and a sprocket 81. The connecting member is composed of, for example, a part of an endless track (caterpillar (registered trademark)) and is composed of a non-annular chain. More specifically, the connecting member 80 is composed of, for example, a crawler belt in which a large number of metal pieces (links) 88 are connected. One end of the connecting member 80 is connected to the rear end of the first advancing / retreating portion 22 in the X direction, and the other end of the connecting member 80 is connected to the lower end of the second advancing / retreating portion 52. .. The connecting member 80 is housed in a part of the first through hole 24 and a part of the second through hole 54 so as to straddle the connecting portion between the first through hole 24 and the second through hole 54. A guide portion 82 made of a material having a small frictional force, for example, a resin material, is provided below the arc-shaped extending hole portion 24b. A part of the connecting member 80 in the extending direction moves in the arc-shaped extending hole portion 24b so as to be guided by the guide portion 82 thereof.

図1に示すように、連結部材80のピース88における最も厚さが厚い箇所のYZ断面は、第1貫通孔24のX方向延在孔部24aのYZ断面よりも僅かに小さく、当該YZ断面に対応する形状を有する。また、スプロケット81は、その外周面の一部が第1貫通孔24の円弧状延在孔部24bの上側屈曲部に沿うように基部21に回転自在に取り付けられる。スプロケット81は、図示しない複数の突起を有する。複数の突起は、周方向に互いに間隔をおいて配置され、各突起は径方向に延在する。各突起は、例えば、連結部材80の隣り合うピース88間に生成される隙間に係合する。連結部材80は、円弧状延在孔部24bに位置する部分の少なくとも一部がスプロケット81に案内される。その結果、連結部材80の進行方向が、Z方向からX方向、又はX方向からZ方向へ円滑に変動可能になる。 As shown in FIG. 1, the YZ cross section of the thickest portion of the piece 88 of the connecting member 80 is slightly smaller than the YZ cross section of the X-direction extending hole portion 24a of the first through hole 24, and the YZ cross section is concerned. It has a shape corresponding to. Further, the sprocket 81 is rotatably attached to the base portion 21 so that a part of the outer peripheral surface thereof is rotatably attached to the upper bending portion of the arcuate extending hole portion 24b of the first through hole 24. The sprocket 81 has a plurality of protrusions (not shown). The plurality of protrusions are arranged so as to be spaced apart from each other in the circumferential direction, and each protrusion extends in the radial direction. Each protrusion engages, for example, a gap created between adjacent pieces 88 of the connecting member 80. At least a part of the connecting member 80 located in the arcuate extending hole portion 24b is guided by the sprocket 81. As a result, the traveling direction of the connecting member 80 can be smoothly changed from the Z direction to the X direction or from the X direction to the Z direction.

台車1は、更に、ラックピニオン機構90を備える。詳しくは、第2進退部52のX方向後側面には、Z方向に延在するラック91が設けられ、柱部51には、ピニオン92が回動自在にX方向後側に取り付けられる。ピニオン92は、ラック91に噛合する。ピニオン92は、Y方向に延在するピニオン軸94(図2参照)のY方向の両端部に設けられる。 The carriage 1 further includes a rack and pinion mechanism 90. Specifically, a rack 91 extending in the Z direction is provided on the rear side surface of the second advancing / retreating portion 52 in the X direction, and a pinion 92 is rotatably attached to the rear side in the X direction on the pillar portion 51. The pinion 92 meshes with the rack 91. Pinions 92 are provided at both ends of the pinion shaft 94 (see FIG. 2) extending in the Y direction in the Y direction.

図2に示すように、台車1は、更にギアボックス96を備える。ピニオン軸94は、ギアボックス96を通過し、例えば転がり軸受を介してギアボックスのケースに回転自在に固定される。ピニオン軸94は、ギアボックス96内に位置する部分に傘歯車(図示せず)を有する。ピニオン軸94の傘歯車は、X方向に延在する軸部材(図示せず)の一方側端部に設けられた傘歯車に噛合する。その軸部材の他方側端部には、ハンドル97が取り付けられる。ラックピニオン機構90及びハンドル97は、寸法調整機構を構成する。 As shown in FIG. 2, the carriage 1 further includes a gearbox 96. The pinion shaft 94 passes through the gearbox 96 and is rotatably fixed to the case of the gearbox via, for example, a rolling bearing. The pinion shaft 94 has a bevel gear (not shown) at a portion located in the gearbox 96. The bevel gear of the pinion shaft 94 meshes with a bevel gear provided at one end of a shaft member (not shown) extending in the X direction. A handle 97 is attached to the other end of the shaft member. The rack and pinion mechanism 90 and the handle 97 constitute a dimensional adjustment mechanism.

上記構成において、ユーザがハンドル97を時計回りに回転させると、上記軸部材がハンドル97側から見たとき時計回りに回転し、軸部材の回転動力が互いに噛合する2つの傘歯車によってピニオン軸94の回転動力に変換される。この回転動力の変換によって、ピニオン軸94が、ピニオン92側から見たとき時計回りに回転し、ピニオン92(図1参照)が時計回りに回転する。その結果、ピニオン92に対して第2進退部52がZ方向上側に移動し、高さ方向延在部50の高さが高くなり、上側係止部62がZ方向上方に移動する。 In the above configuration, when the user rotates the handle 97 clockwise, the shaft member rotates clockwise when viewed from the handle 97 side, and the rotational power of the shaft member meshes with each other. It is converted into the rotational power of. Due to this conversion of rotational power, the pinion shaft 94 rotates clockwise when viewed from the pinion 92 side, and the pinion 92 (see FIG. 1) rotates clockwise. As a result, the second advancing / retreating portion 52 moves upward in the Z direction with respect to the pinion 92, the height of the extending portion 50 in the height direction increases, and the upper locking portion 62 moves upward in the Z direction.

また、第2進退部52がZ方向上側に移動すると、第2進退部52に連結部材80を介してつながっている第1進退部22が、連結部材80に引っ張られてX方向後側に移動し、第1貫通孔24内に移動する。すなわち、第1進退部22が、第2進退部52のX方向上方の動きに連動してX方向後側に移動し、土台部20のX方向長さが短くなる。 When the second reciprocating unit 52 is moved in the Z direction upward, the first forward and reverse part 22 has tuna wants via a connecting member 80 to the second reciprocating unit 52, pulled by the connecting member 80 after the X direction It moves to the side and moves into the first through hole 24. That is, the first advancing / retreating portion 22 moves to the rear side in the X direction in conjunction with the upward movement of the second advancing / retreating portion 52 in the X direction, and the length of the base portion 20 in the X direction becomes shorter.

このようにして、高さ方向延在部50が、図2に示す状態から図4に示す柱部51から第2進退部52がよりZ方向上方に突出した状態に移行すると共に、土台部20が図3に示す状態から図5に示す第1進退部22がより第1貫通孔24に収容された状態に移行する。よって、上側係止部62の上側係止面70と下側係止部32の下側係止面40に係止されたカゴ天井98がよりX方向に近い寝そべった状態になり、その結果、台車1が高さが低い箇所を容易に通過できる。 In this way, the height extending portion 50 shifts from the state shown in FIG. 2 to the state in which the second advancing / retreating portion 52 protrudes upward in the Z direction from the pillar portion 51 shown in FIG. 4, and the base portion 20. Shifts from the state shown in FIG. 3 to the state in which the first advancing / retreating portion 22 shown in FIG. 5 is further accommodated in the first through hole 24. Therefore, the basket ceiling 98 locked to the upper locking surface 70 of the upper locking portion 62 and the lower locking surface 40 of the lower locking portion 32 is in a state of lying closer to the X direction, and as a result, The trolley 1 can easily pass through a place where the height is low.

他方、ユーザがハンドル97を反時計回りに回転させると、上記軸部材がハンドル97側から見たとき反時計回りに回転し、軸部材の回転動力が互いに噛合する2つの傘歯車によってピニオン軸94の回転動力に変換される。この回転動力の変換によって、ピニオン軸94が、ピニオン92側から見たとき反時計回りに回転し、ピニオン92(図1参照)が反時計回りに回転する。その結果、ピニオン92に対して第2進退部52がZ方向下側に移動し、高さ方向延在部50の高さが低くなり、上側係止部62がZ方向下方に移動する。 On the other hand, when the user rotates the handle 97 counterclockwise, the shaft member rotates counterclockwise when viewed from the handle 97 side, and the rotational power of the shaft member meshes with each other. It is converted into the rotational power of. Due to this conversion of rotational power, the pinion shaft 94 rotates counterclockwise when viewed from the pinion 92 side, and the pinion 92 (see FIG. 1) rotates counterclockwise. As a result, the second advancing / retreating portion 52 moves downward in the Z direction with respect to the pinion 92, the height of the extending portion 50 in the height direction becomes low, and the upper locking portion 62 moves downward in the Z direction.

また、第2進退部52がZ方向下側に移動すると、第2進退部52に連結部材80を介してつながっている第1進退部22が、連結部材80に押し出されてX方向前側に移動する。すなわち、第1進退部22が、第2進退部52のX方向下方の動きに連動してX方向前側に移動し、土台部20のX方向長さが長くなる。上述のように、連結部材80のピース88における最も厚さが厚い箇所のYZ断面が、第1貫通孔24のX方向延在孔部24aのYZ断面よりも僅かに小さく、当該YZ断面に対応する形状を有する。したがって、連結部材80が、移動中に上側に屈曲する等の変形を起こしにくく、第1進退部22は連結部材80に円滑な動作で押し出される。 When the second reciprocating unit 52 is moved in the Z-direction lower side, the first forward and reverse part 22 has tuna wants via a connecting member 80 to the second reciprocating unit 52, X-direction are pushed out to the connecting member 80 Move to the front side. That is, the first advancing / retreating portion 22 moves forward in the X direction in conjunction with the downward movement of the second advancing / retreating portion 52 in the X direction, and the length of the base portion 20 in the X direction becomes longer. As described above, the YZ cross section of the thickest portion of the piece 88 of the connecting member 80 is slightly smaller than the YZ cross section of the X-direction extending hole portion 24a of the first through hole 24, and corresponds to the YZ cross section. Has a shape to be used. Therefore, the connecting member 80 is unlikely to be deformed such as bending upward during movement, and the first advancing / retreating portion 22 is pushed out to the connecting member 80 in a smooth operation.

このようにして、高さ方向延在部50が、図4に示す状態から図2に示す第2進退部52がより柱部51の第2貫通孔54に収容された状態に移行すると共に、土台部20が図5に示す状態から図3に示す第1進退部22がより第1貫通孔24からX方向前側に突出した状態に移行する。よって、上側係止部62の上側係止面70と下側係止部32の下側係止面40に係止されたカゴ天井98がよりZ方向に近い立った状態になり、その結果、台車1が幅が低い箇所を容易に通過できる。 In this way, the height extending portion 50 shifts from the state shown in FIG. 4 to the state in which the second advancing / retreating portion 52 shown in FIG. 2 is housed in the second through hole 54 of the pillar portion 51. The base portion 20 shifts from the state shown in FIG. 5 to the state in which the first advancing / retreating portion 22 shown in FIG. 3 protrudes forward from the first through hole 24 in the X direction. Therefore, the basket ceiling 98 locked to the upper locking surface 70 of the upper locking portion 62 and the lower locking surface 40 of the lower locking portion 32 is in a standing state closer to the Z direction, and as a result, The trolley 1 can easily pass through a narrow portion.

上記実施形態によれば、下側係止部32が土台部20の上側であって前側に配置され、上側係止部62が土台部20の後側からZ方向に延在する高さ方向延在部50の上側に配置される。また、ラックピニオン機構90で高さ方向延在部50の高さと土台部20の長さを変更できる。したがって、上側が上側係止部62に係止され、下側が下側係止部32に係止されるカゴ天井98のX方向に対する傾斜角度を適切に調整できる。よって、カゴ天井98の載置状態での高さ及び長さを容易に変更でき、搬入経路の構造に因らず重量物であるカゴ天井98を容易かつ安全に運搬できる。 According to the above embodiment, the lower locking portion 32 is located above the base portion 20 and is arranged on the front side, and the upper locking portion 62 extends in the height direction extending from the rear side of the base portion 20 in the Z direction. It is arranged above the existing portion 50. Further, the rack and pinion mechanism 90 can change the height of the extending portion 50 in the height direction and the length of the base portion 20. Therefore, the inclination angle of the basket ceiling 98 with respect to the X direction, in which the upper side is locked to the upper locking portion 62 and the lower side is locked to the lower locking portion 32, can be appropriately adjusted. Therefore, the height and length of the basket ceiling 98 in the mounted state can be easily changed, and the heavy basket ceiling 98 can be easily and safely transported regardless of the structure of the carry-in route.

また、第1進退部22と第2進退部52が連結部材80を介してつながっている。よって、柱部51からの第2進退部52の突出長さを、ハンドル97で調整するだけで、高さ方向延在部50の高さと土台部20の長さを同時に調整できる。より詳しくは、高さ方向延在部50の高さを高く変更するだけで、それに連動する土台部20の長さを短くでき、高さ方向延在部50の高さを低く変更するだけで、それに連動する土台部20の長さを長くできる。よって、X方向に対するカゴ天井98の傾きを簡単な操作で容易に調整できる。 Further, the first forward and reverse part 22 and the second reciprocating unit 52 are tuna wants via a connecting member 80. Therefore, the height of the extending portion 50 in the height direction and the length of the base portion 20 can be adjusted at the same time only by adjusting the protruding length of the second advancing / retreating portion 52 from the pillar portion 51 with the handle 97. More specifically, the length of the base portion 20 linked to the height can be shortened by simply changing the height of the extending portion 50 in the height direction to a higher height, and the height of the extending portion 50 in the height direction can be changed to a lower height. , The length of the base portion 20 linked to it can be increased. Therefore, the inclination of the basket ceiling 98 with respect to the X direction can be easily adjusted by a simple operation.

また、寸法調整機構が、第2進退部52の後側端部にZ方向に延在するように設けられたラック91と、ラック91に噛合するピニオン92と、ピニオン92を回動させるためのハンドル97と、を有する。よって、ハンドル97を操作するだけで、Z方向に対するカゴ天井98の傾きを簡単な操作で容易に調整できる。 Further, a dimensional adjustment mechanism is provided at the rear end of the second advancing / retreating portion 52 so as to extend in the Z direction, a pinion 92 that meshes with the rack 91, and a pinion 92 for rotating the pinion 92. It has a handle 97 and. Therefore, the inclination of the basket ceiling 98 with respect to the Z direction can be easily adjusted by simply operating the handle 97.

また、連結部材80の少なくとも一部分が、鋼製のチェーンで構成され、台車1が、チェーンを案内するスプロケット81と、チェーンの下側を案内するガイド部82を備える。よって、連結部材80の一部をZ方向からX方向に円滑に屈曲させることができ、連結部材80を介した第1進退部22と第2進退部52の連動動作を円滑なものとできる。 Further, at least a part of the connecting member 80 is composed of a steel chain, and the carriage 1 includes a sprocket 81 for guiding the chain and a guide portion 82 for guiding the lower side of the chain. Therefore, a part of the connecting member 80 can be smoothly bent from the Z direction to the X direction, and the interlocking operation of the first advancing / retreating portion 22 and the second advancing / retreating portion 52 via the connecting member 80 can be made smooth.

また、下側係止部32の下側端部は、第1支点を中心として回転可能な第1円環部材33の外周側に取り付けられ、上側係止部62の上側端部は、第2支点を中心として回転可能な第2円環部材63の外周側に取り付けられる。よって、下側及び上側係止面40,70のX方向に対する傾斜角度を容易に調整できる。 Further, the lower end portion of the lower locking portion 32 is attached to the outer peripheral side of the first annular member 33 that can rotate around the first fulcrum, and the upper end portion of the upper locking portion 62 is the second. It is attached to the outer peripheral side of the second ring member 63 that can rotate around the fulcrum. Therefore, the inclination angles of the lower and upper locking surfaces 40 and 70 with respect to the X direction can be easily adjusted.

更には、下側及び上側係止面40,70が、ゴムで構成されるので、下側及び上側係止面40,70とカゴ天井98との間に大きな摩擦力を生成させることができ、カゴ天井98を下側及び上側係止面40,70で確実に係止できる。また、下側及び上側係止面40,70との接触でカゴ天井98に傷が付くことも抑制できる。 Furthermore, since the lower and upper locking surfaces 40,70 are made of rubber, a large frictional force can be generated between the lower and upper locking surfaces 40,70 and the basket ceiling 98. The basket ceiling 98 can be securely locked by the lower and upper locking surfaces 40 and 70. Further, it is possible to prevent the basket ceiling 98 from being scratched by contact with the lower and upper locking surfaces 40 and 70.

尚、本発明は、上記実施形態およびその変形例に限定されるものではなく、本願の特許請求の範囲に記載された事項およびその均等な範囲において種々の改良や変更が可能である。 The present invention is not limited to the above-described embodiment and its modifications, and various improvements and modifications can be made within the scope of the claims of the present application and the equivalent scope thereof.

例えば、上記実施形態では、寸法調整機構が1つのラックピニオン機構90を含み、ラックピニオン機構90で高さ方向延在部50のZ方向高さと土台部20のX方向長さを同時に調整する場合について説明した。しかし、寸法調整機構は、長孔と締結部材(例えば、ボルトとナット)とを含んでもよく、長孔と締結部材を用いて柱部に対する第2進退部の固定箇所を変えることで、柱部に対する第2進退部の突出量を変動させてもよい。そして、上記突出量を変動させることで、第2進退部に連結部材を介して接続された第1進退部をX方向に移動させて、高さ方向延在部のZ方向高さと土台部のX方向長さを同時に調整してもよい。 For example, in the above embodiment, the dimension adjusting mechanism includes one rack and pinion mechanism 90, and the rack and pinion mechanism 90 simultaneously adjusts the height of the extending portion 50 in the height direction in the Z direction and the length of the base portion 20 in the X direction. Was explained. However, the dimension adjusting mechanism may include an elongated hole and a fastening member (for example, a bolt and a nut), and by using the elongated hole and the fastening member to change the fixing position of the second advancing / retreating portion to the column portion, the column portion The amount of protrusion of the second advancing / retreating portion with respect to the relative may be varied. Then, by varying the amount of protrusion, the first advancing / retreating portion connected to the second advancing / retreating portion via the connecting member is moved in the X direction, and the height of the extending portion in the height direction in the Z direction and the base portion are moved. The length in the X direction may be adjusted at the same time.

また、土台部20の第1進退部22と高さ方向延在部50の第2進退部52とを連結部材80で繋ぎ、1つのラックピニオン機構90で高さ方向延在部の高さのみを調整することで、高さ方向延在部50のZ方向高さと土台部20のX方向長さを同時に調整する場合について説明した。しかし、高さ方向延在部のZ方向高さと、土台部のX方向長さを、互いに独立に調整する構成でもよく、例えば、寸法調整機構は、高さ方向延在部のZ方向高さを調整するためのラックピニオン機構又は長孔及び締結部材と、土台部のX方向長さを調整するためのラックピニオン機構又は長孔及び締結部材と、を含んでもよい。このようにして、連結部材、スプロケット、及びガイド部を省略してもよい。 Further, the first advancing / retreating portion 22 of the base portion 20 and the second advancing / retreating portion 52 of the extending portion 50 in the height direction are connected by a connecting member 80, and only the height of the extending portion in the height direction is provided by one rack pinion mechanism 90. The case where the height of the extending portion 50 in the height direction in the Z direction and the length of the base portion 20 in the X direction are adjusted at the same time has been described. However, the height of the extending portion in the height direction in the Z direction and the length of the base portion in the X direction may be adjusted independently of each other. For example, the dimension adjusting mechanism is the height of the extending portion in the height direction in the Z direction. A rack and pinion mechanism or a long hole and a fastening member for adjusting the height of the base portion and a rack and pinion mechanism or a long hole and a fastening member for adjusting the length of the base portion in the X direction may be included. In this way, the connecting member, the sprocket, and the guide portion may be omitted.

また、土台部20の長さと、高さ方向延在部50の高さを、ラックピニオン機構90で調整する場合について説明した。しかし、土台部の長さの調整と高さ方向延在部の高さの調整のうちの少なくとも一方を、電動シリンダ又は油圧ジャッキを用いて行ってもよい。 Further, a case where the length of the base portion 20 and the height of the extending portion 50 in the height direction are adjusted by the rack and pinion mechanism 90 has been described. However, at least one of the adjustment of the length of the base portion and the adjustment of the height of the extending portion in the height direction may be performed by using an electric cylinder or a hydraulic jack.

また、第1円環部材33が、静止摩擦力よりも大きい力が加わると突出部39の中心軸を支点として回動し、第2円環部材63が、静止摩擦力よりも大きい力が加わると突出部69の中心軸を支点として回動する場合について説明した。しかし、第1及び第2円環部材のうちの少なくとも一方と、突出部との間に転がり軸受を配置してもよく、当該少なくとも一方が突出部に対して自在に回転可能としてもよい。なお、この場合、第1及び第2円環部材のうちの少なくとも一方の回転角度を適切に調整した後に、該少なくとも一方の回転をできなくするストッパ機構が設けられると好ましい。係るストッパ機構は、例えば、車イスにおいて停止時に車輪を移動できなくするストッパ等の公知の機構で容易に実現できる。 Further, when a force larger than the static friction force is applied to the first annular member 33, the first annular member 33 rotates about the central axis of the protruding portion 39 as a fulcrum, and a force larger than the static friction force is applied to the second annular member 63. The case of rotating with the central axis of the protruding portion 69 as a fulcrum has been described. However, a rolling bearing may be arranged between at least one of the first and second annular members and the protrusion, and at least one of them may be freely rotatable with respect to the protrusion. In this case, it is preferable to provide a stopper mechanism that prevents the rotation of at least one of the first and second ring members after appropriately adjusting the rotation angle. Such a stopper mechanism can be easily realized by, for example, a known mechanism such as a stopper that prevents the wheel from moving when stopped in a wheelchair.

また、下側及び上側係止部32,62が、第1及び第2円環部材33,63に固定されて回転可能である場合について説明したが、下側及び上側係止部のうちの少なくとも一方は、回転不可能であってもよい。また、下側及び上側係止面40,70がゴムで構成される場合について説明したが、下側及び上側係止面のうちの少なくとも一方は、ゴム以外の材料で構成されてもよい。また、板状材が、エレベーターのカゴのカゴ天井である場合について説明したが、板状材は、板形状を有する如何なる材であってもよく、例えばガラス板等であってもよい。 Further, the case where the lower and upper locking portions 32 and 62 are fixed to the first and second annular members 33 and 63 and can rotate has been described, but at least one of the lower and upper locking portions has been described. One may be non-rotatable. Further, although the case where the lower and upper locking surfaces 40 and 70 are made of rubber has been described, at least one of the lower and upper locking surfaces may be made of a material other than rubber. Further, although the case where the plate-shaped material is the basket ceiling of the elevator basket has been described, the plate-shaped material may be any material having a plate shape, for example, a glass plate or the like.
