Description
【０００１】[0001]
本考案は手押し運搬車の方向変換装置に関するものである。 The present invention relates to a direction changing device for a hand cart.
【０００２】[0002]
荷台の前方に一対の自在キャスターを装置し、荷台の後部に立設した操作ハン ドルをこじったり、或いは横方向に押し付けることによって前記自在キャスター を強制的に旋回させて方向変換を図るようにしているものが一般である。 A pair of swivel casters is installed in front of the loading platform, and the operation handle installed at the rear of the loading platform is pryed or pushed laterally to forcefully swivel the swivel casters to change the direction. Those that are present are general.
【０００３】[0003]
しかしながら、従来例においては、積荷が重い場合、操作ハンドルの操作に大 きな力を要し、方向変換が極めて難しい。 However, in the conventional example, when the load is heavy, a large force is required to operate the operation handle, and it is extremely difficult to change the direction.
【０００４】 本考案は斯様な従来例に着目して案出したものである。The present invention has been made by paying attention to such a conventional example.
【０００５】[0005]
荷台に、一対の旋回自在な自在キャスターを装置し、該自在キャスターの旋回 枠に連動杆をわたして互いに回動自在に接続すると共に、荷台に回動自在に立設 した操作ハンドルの下端部に腕杆を突設し、該腕杆の自由端部と前記連動杆を互 いに回動自在に接続した構成とする。 A pair of freely rotatable swivel casters are installed on the loading platform, and interlocking rods are connected to the swivel frame of the swivel casters to rotatably connect them to each other. The arm rod is provided so as to project, and the free end portion of the arm rod and the interlocking rod are rotatably connected to each other.
【０００６】[0006]
図面は本考案に係る手押し運搬車の方向変換装置の一実施例を示し、図１は縦 断面図、図２は底面図、図３は手押し運搬車の正面図、図４は側面図である。 1 is a longitudinal sectional view, FIG. 2 is a bottom view, FIG. 3 is a front view of a hand truck, and FIG. 4 is a side view. .
【０００７】 実施例の手押し運搬車Ａは、荷台１の前部側に一対の固定キャスター２，２を 、後部側に一対の旋回自在な自在キャスター３，３をそれぞれ装置し、後部中央 には操作ハンドル４を回動自在に立設して構成したもので、この運搬車Ａの操作 ハンドル４は、前記荷台１に組付けた支持筒５に主体杆部６を貫通させ、該主体 杆部６の下部側に設けた鍔部片７を前記支持筒５に載置支持させて前記の通り、 荷台１の後部中央に回動自在に立設させ、主体杆部６の上部には把手杆部８を設 けたものである。The hand cart A of the embodiment has a pair of fixed casters 2 and 2 on the front side of the loading platform 1 and a pair of freely rotatable swivel casters 3 and 3 on the rear side thereof. The operating handle 4 of the transport vehicle A is rotatably provided upright. The operating handle 4 of the carrier A has a supporting rod 5 attached to the loading platform 1 and a main rod 6 which penetrates the main operating rod 4. As described above, the collar piece 7 provided on the lower side of the support 6 is placed and supported on the support cylinder 5, and is rotatably erected upright in the center of the rear portion of the loading platform 1 and the handle rod 6 is provided on the upper portion of the main rod portion 6. Part 8 is provided.
【０００８】 前記の自在キャスター３は、荷台１に固定した取付枠９と該取付枠９にベアリ ング装置１０を介して組付けた旋回枠１９とで構成し、旋回枠１９に車輪２２を 転動自在に支持させると共に、この旋回枠１９の上部片１９ａの一側に接続部片 １１を突設したものである。The swivel caster 3 is composed of a mounting frame 9 fixed to the platform 1 and a swivel frame 19 mounted on the mounting frame 9 via a bearing device 10, and wheels 22 are swung on the swivel frame 19. In addition to being movably supported, a connecting piece 11 is provided on one side of an upper piece 19a of the revolving frame 19 so as to project.
【０００９】 自在キャスター３に設けた接続部片１１には連動杆１２をわたして一対の自在 キャスター３，３を互いに回動自在に接続し、連動杆１２は基部片１３の両側に 側部片１４，１４を、中央に中央部片１５をそれぞれ突設したほぼ「山」の字形 で構成し、側部片１４を自在キャスター３の接続部片１１にピン１６で互いに回 動自在に枢着して自在キャスター３，３間にわたしたものである。An interlocking rod 12 is connected to a connecting piece 11 provided on the swivel caster 3 to rotatably connect a pair of swivel casters 3, 3 to each other. The interlocking rod 12 is provided on both sides of a base piece 13 with side pieces. 14 and 14 are formed in a substantially "mountain" shape with a central piece 15 projecting in the center, and the side piece 14 is pivotally attached to the connecting piece 11 of the free caster 3 by a pin 16 so as to be rotatable relative to each other. It is the one between the free casters 3 and 3.
【００１０】 連動杆１２の中央部片１５の自由端部には接続ピン２０を突設し、この接続ピ ン２０を腕杆１７の自由端側に設けた長孔１８に移動自在に係合し、腕杆１７は 基部において操作ハンドル４の前記主体杆部６の下面にねじ２１で止着して操作 ハンドル４の下端部に突設したものである。A connecting pin 20 is projectingly provided at a free end portion of a central portion piece 15 of the interlocking rod 12, and the connecting pin 20 is movably engaged with a long hole 18 provided at a free end side of an arm rod 17. The arm rod 17 is fixed to the lower surface of the main rod portion 6 of the operation handle 4 with a screw 21 at the base portion and protrudes from the lower end portion of the operation handle 4.
【００１１】 しかして、操作ハンドル４を回動させると、操作ハンドル４に支持させた腕杆 １７は同時に回動し、腕杆１７に備えた長孔１８に接続ピン２０を係合してある ので、接続ピン２０は操作ハンドル４の回動方向に押圧され、この結果、連動杆 １２は自在キャスター３，３の旋回枠１９，１９を押圧し、旋回枠１９，１９は 方向を変え、車輪２２，２２の方向が同期して一定方向に向き、手押し運搬車の 方向変換が行われる。Then, when the operation handle 4 is rotated, the arm rod 17 supported by the operation handle 4 is simultaneously rotated, and the connection pin 20 is engaged with the long hole 18 provided in the arm rod 17. Therefore, the connecting pin 20 is pressed in the rotation direction of the operation handle 4, and as a result, the interlocking rod 12 presses the swivel frames 19, 19 of the free casters 3, 3, and the swivel frames 19, 19 change the direction, and The directions of 22, 22 are synchronously directed to a fixed direction, and the direction of the cart is changed.
【００１２】 なお、自在キャスター３，３を荷台１の前部側に配しても良い。The flexible casters 3, 3 may be arranged on the front side of the loading platform 1.
【００１３】[0013]
本考案は前記の通りの構成であるから、操作ハンドルの回動操作によって自在 キャスターの方向を任意に設立することができ、実用的である。 Since the present invention is configured as described above, the direction of the universal caster can be arbitrarily established by rotating the operation handle, which is practical.
