The brake can be applied to prevent accidents.

以下、図面について本発明の実施の形態を詳細に説明する。図１は本発明の運搬台車の実施形態を示すブレーキ解除時の側面図、図２は同上平面図、図３はブレーキ時の側面図、図４は同上平面図で、鉄製またはアルミニウム合金製の角パイプによるフレーム６と、このフレーム６の上部に接合される鉄製またはアルミニウム合金製の載置板であるベース７とで構成される台車本体の下側に、台座２ｂに車輪２ａを回転自在に取付けたキャスター２を設けたものである。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view when a brake is released showing an embodiment of a transport carriage of the present invention, FIG. 2 is a plan view of the same, FIG. 3 is a side view of a brake, FIG. 4 is a plan view of the same, and is made of iron or aluminum alloy A wheel 2a is rotatable on a pedestal 2b on the lower side of a cart body composed of a frame 6 made of a square pipe and a base 7 which is a mounting plate made of iron or aluminum alloy joined to the upper portion of the frame 6. An attached caster 2 is provided.

キャスター２は、前記台車本体の裏面の周辺部の少なくとも四隅に取付けたものの他に、少なくとも四隅に取付けた旋回キャスター２をつなぐ輪郭線の内側で、使用時の進行方向と同じ方向の縦列に２輪以上のキャスター２を設けた。   In addition to the casters 2 attached to at least the four corners of the peripheral portion of the rear surface of the bogie body, the casters 2 are arranged in a column in the same direction as the traveling direction at the time of use inside the contour line connecting the swivel casters 2 attached to at least the four corners. A caster 2 having a ring or more was provided.

かかる台車本体の四隅の角部では、フレーム６を構成する縦横の角パイプをアルミニウムなどによる押出し形材で形成、全体形状が平面Ｌ字形であるコーナー部材５で接合する。   At the corners of the four corners of the carriage main body, vertical and horizontal square pipes constituting the frame 6 are formed of extruded shapes made of aluminum or the like, and joined by a corner member 5 whose overall shape is a flat L shape.

コーナー部材５は、その詳細を図８、図９に示すと、手押し棒３が挿着される筒状で外周面が円弧状の挿入孔１２をＬ字形の角部に形成し、この挿入孔１２の箇所から互いに直交する方向にフレーム６の取付部として対向する側壁部材１３ａ，１３ｂをそれぞれ垂直に突設した。   The details of the corner member 5 are shown in FIGS. 8 and 9, and an insertion hole 12 having a cylindrical shape and an arcuate outer peripheral surface is formed in an L-shaped corner portion. Side wall members 13a and 13b that face each other as attachment portions of the frame 6 in a direction orthogonal to each other from 12 locations are vertically projected.

前記側壁部材１３ａ，１３ｂのうち、外側に位置する側壁部材１３ｂは、挿入孔１２の外周部に連成するものであり、挿入孔１２との接続部分では挿入孔１２と同じ高さを備え、端部ではフレーム６とほぼ同じ高さを備えて、底辺が傾斜部１４に形成される。   Of the side wall members 13a and 13b, the side wall member 13b located on the outside is continuous with the outer peripheral portion of the insertion hole 12, and is provided with the same height as the insertion hole 12 at the connection portion with the insertion hole 12, The end portion has substantially the same height as the frame 6, and the bottom is formed in the inclined portion 14.

挿入孔１２の底部には手押し棒３の脱落を防止するための支持板１２ａが設けてある。   At the bottom of the insertion hole 12, a support plate 12a for preventing the push bar 3 from falling off is provided.

以上のようにしてフレーム６にコーナー部材５を取付けるには、対向する側壁部材１３ａ，１３ｂの間の空隙にフレーム６を差込む。この場合、側壁部材１３ａ，１３ｂの間は、上下とも開口に形成されているから、フレーム６をこの側壁部材１３ａ，１３ｂの間に差込んでも、これとは反対にコーナー部分に位置する縦横のフレーム６にコーナー部材５を差込んでもよい。また、差込方向も、上下のいずれからでも行える。   In order to attach the corner member 5 to the frame 6 as described above, the frame 6 is inserted into the gap between the opposing side wall members 13a and 13b. In this case, since the upper and lower sides are formed between the side wall members 13a and 13b, even if the frame 6 is inserted between the side wall members 13a and 13b, the vertical and horizontal positions located at the corners are opposite to this. The corner member 5 may be inserted into the frame 6. Also, the insertion direction can be performed from either the top or bottom.

側壁部材１３ａ，１３ｂの間にフレーム６が挿入された状態で、リベット１５またはボルトでコーナー部材５をフレーム６に固定する。このフレーム６との結合はリベット１５などを使用するものであるから、アルミニウム製のコーナー部材５に対して、フレーム６が同材質のものである必要はない。   In a state where the frame 6 is inserted between the side wall members 13a and 13b, the corner member 5 is fixed to the frame 6 with rivets 15 or bolts. Since the rivet 15 or the like is used for the connection with the frame 6, the frame 6 does not have to be made of the same material with respect to the aluminum corner member 5.

以上のようにしてコーナー部材５を取付けた運搬台車は、他物に接触しやすい角部に外周部が円弧状のコーナー部材５が取付けられているから、衝撃が吸収され、コーナー部材５が損傷するなどして交換する場合は、リベット１５などを外すだけで取外しでき、新規のコーナー部材５もリベット１５で固定するだけでよいから簡単に交換できる。   As described above, the transport cart with the corner member 5 attached has the corner member 5 having an arcuate outer peripheral portion attached to a corner portion that is likely to come into contact with other objects, so that the impact is absorbed and the corner member 5 is damaged. When exchanging, for example, it can be removed simply by removing the rivet 15 and the like, and the new corner member 5 can be simply exchanged because it is only necessary to fix it with the rivet 15.

また、コーナー部材５には手押し棒３の挿入孔１２が形成され、ここの差込口には手押し棒３からの過重なモーメントがかかる。コーナー部材５が他物との接触だけでなく、このように内側からも変形しやすい部位を備えていることを勘案すると、かかるコーナー部材５の交換を容易に行えるようにしたことは実効的である。   In addition, an insertion hole 12 for the hand bar 3 is formed in the corner member 5, and an excessive moment from the hand bar 3 is applied to the insertion port. Considering that the corner member 5 is not only in contact with other objects but also has a portion that is easily deformed from the inside as described above, it is effective that the corner member 5 can be easily replaced. is there.

ところで、キャスター２には、ブレーキ付きキャスターとブレーキ付きでないキャスターとがあり、ブレーキ付きキャスターは台車本体の四隅のコーナー部のうち、前後のいずれかの左右の双方、もしくは一方に設けられる。   By the way, the caster 2 includes a caster with a brake and a caster without a brake, and the caster with a brake is provided on either one of the front and rear left and right or one of the four corners of the carriage body.

本発明は、前記キャスターを設ける台車本体の四隅のコーナー部のうち、ブレーキ付きキャスターを裏側に設けたコーナー部を着色（例えば、赤や緑）した。   In the present invention, among the corner portions at the four corners of the carriage main body on which the casters are provided, the corner portions on which the casters with brakes are provided on the back side are colored (for example, red or green).

この着色１は、コーナー部がアルミニウム合金素材の場合は焼き付け等で行い、コーナー部を形成するコーナー部材５の前記側壁部材１３ａ，１３ｂのうち、外側に位置する側壁部材１３ｂの全面について施す。   The coloring 1 is performed by baking or the like when the corner portion is made of an aluminum alloy material, and is applied to the entire side wall member 13b located on the outer side among the side wall members 13a and 13b of the corner member 5 forming the corner portion.

ブレーキ付きキャスターは、図５〜図７に示すように、ヨーク（把持体）２ｃと、車輪２ａと、ブレーキシュー１６と、ブレーキペダル１７とからなる。   As shown in FIGS. 5 to 7, the caster with brake includes a yoke (gripping body) 2 c, a wheel 2 a, a brake shoe 16, and a brake pedal 17.

ヨーク（把持体）２ｃは、金属板を曲げ加工してなるものとしており、取付板９の下方に取付けられ、ブレーキシュー１６は、金属板を曲げ加工してなるものとしており、ブレーキライニング（図示せず）を設けたものとしている。   The yoke (gripping body) 2c is formed by bending a metal plate, and is attached below the mounting plate 9. The brake shoe 16 is formed by bending the metal plate, and the brake lining (see FIG. (Not shown).

ブレーキペダル１７は、金属板を曲げ加工してなるものとしており、一端の操作部１８を踏み付けて揺動させることにより、ブレーキシュー１６を車輪２ａに押しつけて車輪２ａを固定するものである。   The brake pedal 17 is formed by bending a metal plate, and presses the brake shoe 16 against the wheel 2a to fix the wheel 2a by stepping on and swinging the operation portion 18 at one end.

ブレーキペダル１７は、前記一端の操作部１８を閉塞端とし、中央に空隙１９を形成したコ字形アームからなり、該アームは緩やかに凹形を描くように湾曲し、かつ前記操作部１８は端を跳ね上げるように形成した。   The brake pedal 17 is composed of a U-shaped arm having the operation portion 18 at one end as a closed end and a gap 19 formed in the center. The arm is gently curved to form a concave shape, and the operation portion 18 has an end. Formed to jump up.

ブレーキ時には、車輪２ａはこのブレーキペダル１７の空隙１９に入り込むように位置付ける。   During braking, the wheel 2a is positioned so as to enter the gap 19 of the brake pedal 17.

また、前記跳ね上げるように形成した操作部１８には、足踏片２０を前方に突き出させて設けた。   Further, the operation piece 18 formed so as to be flipped up is provided with a foot piece 20 protruding forward.

そして、ブレーキペダル１７は、図１、図２に示すように、ブレーキ解除時に車輪２ａが前後方向に向いた場合に、平面視して、前記操作部１８が台車本体の周囲から顕出するものとした。   As shown in FIGS. 1 and 2, the brake pedal 17 is the one in which the operation unit 18 is exposed from the periphery of the main body of the carriage in a plan view when the wheel 2 a is directed in the front-rear direction when the brake is released. It was.

ブレーキ操作は、ブレーキペダル１７を足で踏みこむと、ブレーキペダル１７が押し下がり、ブレーキシュー１６が車輪２ａに押しつけてられて車輪２ａを固定し、ブレーキ解除にはブレーキペダル１７を足で押し上げると、ブレーキシュー１６の車輪２ａへの係合が解かれるものである。   When the brake pedal 17 is depressed with the foot, the brake pedal 17 is depressed, the brake shoe 16 is pressed against the wheel 2a to fix the wheel 2a, and the brake pedal 17 is lifted with the foot to release the brake. The engagement of the brake shoe 16 with the wheel 2a is released.

ブレーキ付きキャスターは、台車本体の裏面の周辺部の少なくとも四隅のいずれかに取付ける場合に、四隅には手押し棒３を挿着するためのコーナー部材５が取付けられることから、手押し棒３、コーナー部材５を避けて回転できるように「旋回偏心半径＋キャスター半径」の分だけ垂下部分から台車本体の内側に入った箇所に取付けられる。   When the caster with a brake is attached to at least one of the four corners of the back surface of the carriage body, the corner member 5 for inserting the hand bar 3 is attached to the four corners. In order to be able to rotate while avoiding 5, it is attached to a place that enters the inside of the cart body from the hanging part by the amount of “swivel eccentric radius + caster radius”.

その結果、車輪２ａの向きやブレーキ状態では、台車本体の裏面に隠れてブレーキペダルの位置がわからない。   As a result, in the direction of the wheel 2a and the brake state, the position of the brake pedal is not known because it is hidden behind the back surface of the carriage body.

そこで、着色１により、キャスターを設ける台車本体の四隅のコーナー部のうち、ブレーキ付きキャスターを裏側に設けたコーナー部を把握でき、これによりブレーキ付きキャスターの存在を認識できるとともに、ブレーキ解除時に車輪２ａが前後方向に向いた場合に、ブレーキペダル１７が台車本体の周囲から顕出するので、確実にブレーキを掛けることができる。   Therefore, by coloring 1, among the four corners of the main body of the carriage on which the casters are provided, the corner provided with the casters with brakes can be grasped, whereby the presence of the casters with brakes can be recognized, and the wheels 2a are released when the brake is released. Since the brake pedal 17 is exposed from the periphery of the bogie body when is directed in the front-rear direction, the brake can be reliably applied.

なお、前記運搬台車は、前記台車本体の裏面の周辺部の少なくとも四隅に取付けたものの他に、少なくとも四隅に取付けた旋回キャスター２をつなぐ輪郭線の内側で、使用時の進行方向と同じ方向の縦列に２輪以上のキャスターを設けたものとしたが、これに限定されるものでなく、例えば、特開２００９−２２７０４２号公報にあるように、平面長方形の台車本体の、長手方向の左右両側にそれぞれ縦列に３輪ずつ旋回キャスター２を軸着した運搬台車において、前記３輪のキャスターのうちの真中のキャスターを前後の２輪の旋回キャスターよりも外側に配置させたものや、台車本体の裏面の周辺部の少なくとも四隅にのみキャスターを設けたものなど、種々のタイプのものに適用できる。   In addition to the one attached to at least the four corners of the peripheral portion of the back surface of the carriage body, the transporting carriage is located at the inner side of the contour line connecting the swiveling casters 2 attached to at least the four corners, and has the same direction as the traveling direction during use. Although two or more casters are provided in the column, the present invention is not limited to this. For example, as disclosed in Japanese Patent Application Laid-Open No. 2009-227042, the left and right sides in the longitudinal direction of a flat rectangular cart body In each of the transport carts in which the three swivel casters 2 are axially mounted, the middle caster of the three-wheel casters is arranged outside the front and rear two swivel casters, The present invention can be applied to various types such as those provided with casters only at least at the four corners of the peripheral portion of the back surface.
