Abstract

[Problem] To provide a dolly that is easy to organize and suited to storing and saving, as well as moving, loads. [Solution] The attitude of an operating rod 31 and the position of an operating tool 30 are manipulated so as to dispose a connecting part 33 of a lifter 32 below a connection-receiving part 15 of a carrier part 11. By tiltingly manipulating the operating rod 31, the connecting part 33 of the lifter 32 is locked to the connection-receiving part 15 of the carrier part 11. With first and second wheels 35 serving as a fulcrum, the tilting moment acting on the operating rod 31 due to the manipulation exerts an upward push on the connection-receiving part 15 whereto the connecting part 33 is locked, the first and second wheels 35 move toward a position below the connection-receiving part 15, and as a result, a supporting part 12 of the carrier part 11 lifts off a floor surface FL, thus completing the connection.

台車、これに使用される台車本体および操作具Dolly, dolly main body and operation tool used therefor

　本発明は、重量物等を移動、保持、保管しておくための台車に関する。 The present invention relates to a carriage for moving, holding and storing heavy objects and the like.

　重量物を運搬する従来の台車としては、荷台部の下面に複数の自在キャスタが設けられるとともに、荷台部の一側部に把手（操作具）を設けたものが知られている（例えば、特許文献１）。 As a conventional carriage for carrying heavy objects, there is known one in which a plurality of free casters are provided on the lower surface of a loading platform, and a handle (operating tool) is provided on one side of the loading platform (for example, Literature 1).

　例えば、工作機械で加工される金属材料や加工後のワークは、比較的重量が重く、台車への積載や台車からの積み下ろしが頻繁に必要であると、工数も増大するし、作業者の負担も大きい。
　したがって、可能な限り物品の台車への積載や台車からの積み下ろしを減らす必要がある。一つの方法としては、物品を台車へ積載したのちは、可能な限り当該物品を台車上で保管する方法が考えられる。
　しかしながら、従来の台車は、外力が作用すると容易に移動してしまうため、ストッパ等を設ける必要がある。また、従来の台車では、作業者が操作するための把手を備えているため、多数の台車を整理する際に、把手が邪魔になるという問題もある。 For example, metal materials processed by machine tools and workpieces after machining are relatively heavy, and if loading on a truck and loading and unloading from a truck are frequently required, the number of man-hours increases and the burden on the worker Too big.
Therefore, there is a need to reduce loading and unloading of articles on the cart as much as possible. One possible method is to store the articles on the carriage and then store the articles on the carriage as much as possible.
However, since the conventional truck easily moves when an external force acts, it is necessary to provide a stopper or the like.

　台車１は、台車本体１０と、台車本体１０に取り外し可能に連結される操作具３０とで構成される。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1A to FIG. 3 show the structure of a carriage according to an embodiment of the present invention. In the figure, L1 and L2 indicate the longitudinal direction of the carriage 1 in a horizontal plane parallel to the floor surface FL, and M1 and M2 indicate transverse directions orthogonal to the longitudinal direction L1 and L2 of the carriage 1 in the horizontal plane Indicates
The dolly 1 includes a dolly main body 10 and an operation tool 30 detachably connected to the dolly main body 10.

　台車本体１０は、図２等に示すように、矩形状の外形を有する荷台部１１と、荷台部１１の下面１１ｂの長手方向のＬ１側の端部に設けられた２つの車輪１３Ａ，１３Ｂと、荷台部１１の下面１１ｂの長手方向のＬ２側の端部に設けられた２つの支持部１２Ａ，１２Ｂと、被連結部１５とを有する。
　荷台部１１は、運搬すべき物品が積載されるが、金属材料等で形成された板材であってもよいし、フレーム部材を組み合わせものであってもよい。また、板材やフレーム以外にも、金属製の網かごを荷台部として採用し、その下面に車輪（キャスタ）を設けたものを採用することも可能である。重量物だけでなく、大容量の物品の運搬、保持も可能となる。
　車輪１３Ａ，１３Ｂは、荷台部１１の下面１１ｂの横方向Ｍ１，Ｍ２の両端部に設けられ、軸線Ｋ１を中心に回転自在となっており、車輪１３Ａ，１３Ｂの向きは固定されている。 As shown in FIG. 2 and the like, the bogie main body 10 includes a loading unit 11 having a rectangular outer shape, and two

wheels

13A and 13B provided at an end of the lower surface 11b of the loading unit 11 in the longitudinal direction L1. The support portion 12 has two

support portions

12A and 12B provided at an end portion on the L2 side in the longitudinal direction of the lower surface 11b of the loading platform 11, and a connected portion 15.
Although the loading part 11 is loaded with articles to be transported, it may be a plate made of a metal material or the like, or may be a combination of frame members. Moreover, it is also possible to employ | adopt what employ | adopted the metal mesh cage as a loading platform part and provided the wheel (caster) in the lower surface besides a board | plate material and a flame | frame. Not only heavy items but also large-volume articles can be transported and held.
The

wheels

13A and 13B are provided at both ends in the lateral direction M1 and M2 of the lower surface 11b of the loading section 11, are rotatable around the axis K1, and the directions of the

wheels

13A and 13B are fixed.

　支持部１２Ａ，１２Ｂは、鋼材等で形成され、荷台部１１の下面１１ｂの車輪１３Ａ，１３Ｂ側とは反対側の端部であって、横方向Ｍ１，Ｍ２の両端部に設けられている。支持部１２Ａ，１２Ｂは、下端面１２ｂが床面ＦＬに接触する。支持部１２Ａ，１２Ｂが床面ＦＬに接触した状態では、２つの支持部１２Ａ，１２Ｂと２つの車輪１３Ａ，１３Ｂとは協働して荷台部１１をほぼ水平に保持するとともに、荷台１１からの荷重を支える。支持部１２Ａ，１２Ｂの下端面１２ｂが床面ＦＬに接触していることにより、荷台部１１に積載される物の重量が大きいほど、下端面１２ｂと床面ＦＬとの摩擦力が大きくなり、台車本体１０が床面ＦＬ上を移動しにくくなる。 The

support portions

12A and 12B are made of steel or the like, and are end portions of the lower surface 11b of the bed portion 11 opposite to the

wheels

13A and 13B, and are provided at both end portions in the lateral direction M1 and M2. The lower end surface 12b of the

support portions

12A and 12B contacts the floor surface FL. In a state in which the

support portions

12A and 12B are in contact with the floor surface FL, the two

support portions

12A and 12B and the two

wheels

13A and 13B cooperate to hold the bed portion 11 substantially horizontally, and from the bed 11 Support the load. As the lower end surface 12b of the

support portions

12A and 12B is in contact with the floor surface FL, the friction force between the lower end surface 12b and the floor surface FL increases as the weight of the object loaded on the bed portion 11 increases. It becomes difficult for the dolly body 10 to move on the floor surface FL.

　被連結部１５は、２つの支持部１２Ａ，１２Ｂの間の略中間位置に設けられ、金属製の円筒部材からなり、貫通孔１５ａを有するとともに、円環状の下端面１５ｂが後述する操作具３０の連結部３３と係合する。被連結部１５は、溶接により、荷台１１の下面１１ｂに固定されている。 The connected portion 15 is provided at a substantially intermediate position between the two

support portions

12A and 12B, is formed of a metal cylindrical member, has a through hole 15a, and has an operation tool 30 whose annular lower end surface 15b will be described later. Engage with the connector 33 of the The connected portion 15 is fixed to the lower surface 11 b of the loading platform 11 by welding.

　操作具３０は、図３に示すように、直線状に延びる操作竿部３１と、操作竿部３１の下端部側に設けられたリフター部３２とを有する。
　操作竿部３１の上端部には、台車１を操作する作業者が把持するための把手部３１ａが操作竿部３１に直交する向きに水平に延びるように設けられている。 As shown in FIG. 3, the operating tool 30 has an operating rod portion 31 extending linearly and a lifter portion 32 provided on the lower end side of the operating rod portion 31.
At an upper end portion of the operation collar portion 31, a grip portion 31a for a worker who operates the carriage 1 to grip is provided so as to extend horizontally in a direction perpendicular to the operation collar portion 31.

　リフター部３２は、操作竿部３１の下端部に設けられており、操作竿部３１の下端部に形成された連結部３３と、この連結部３３から操作竿部３１の軸線Ｓ１に略直交する軸線Ｔ１方向に延びる車軸３７に回転自在に支持された車輪３５Ａ，３５Ｂと、連結部３３から突出して形成される２つのアーム部３６Ａ，３６Ｂ（以下、アーム部３６とも言う。）と、を有する。
　連結部３３の上端面３３ａに、円柱状の突出部３４が設けられている。突出部３４は、台車本体１０の被連結部１５を構成する円筒部材の貫通孔１５ａに挿入可能に形成されている。 The lifter portion 32 is provided at the lower end portion of the operating rod portion 31, and the connecting portion 33 formed at the lower end portion of the operating rod portion 31 and the connecting portion 33 are substantially orthogonal to the axis S1 of the operating rod portion 31 It has

wheels

35A, 35B rotatably supported by an axle 37 extending in the direction of the axis T1, and two

arm portions

36A, 36B (hereinafter also referred to as arm portions 36) formed to project from the connecting portion 33. .
A cylindrical projecting portion 34 is provided on the upper end surface 33 a of the connecting portion 33. The projecting portion 34 is formed so as to be insertable into the through hole 15 a of the cylindrical member that constitutes the coupled portion 15 of the carriage body 10.

　操作具３０の操作竿３１は、車輪３５Ａ，３５Ｂが回転自在に設けられていることから、支持がなければ起立した状態を維持することができない。しかしながら、図４等に示すように、アーム部３６が床面ＦＬに接触して操作竿３１の傾動を規制することで、操作竿３１は、若干傾斜した状態で起立状態が維持されている。 Since the

wheels

35A and 35B are rotatably provided, the operating rod 31 of the operating tool 30 can not maintain the standing state if there is no support. However, as shown in FIG. 4 and the like, the arm portion 36 contacts the floor surface FL to restrict the tilting of the operating rod 31, whereby the operating rod 31 is maintained in the upright state in a slightly inclined state.

　次に、台車本体１０と操作具３０との連結動作について説明する。
　台車本体１０と操作具３０とを連結するには、先ず、図４に示すように、操作具３０を
リフター部３２の連結部３３が荷台部１０の被連結部１５の下方に位置するように操作竿部３１の姿勢（傾斜）および操作具３０の位置を調整する。
　具体的には、床面ＦＬに設置された荷台部１１に対して、図５Ａに示すように、操作具３０を接近させていく。この時、連結部３３の突出部３４が被係合部１５の下端面１５よりも下方に位置するように、操作竿３１の傾斜を調整する。なお、図４に示したように、操作竿３１が車輪３５とアーム３６により支えられた状態では、連結部３３の突出部３４が被係合部１５の下端面１５よりも下方に配置されるように設計されている。 Next, the connecting operation of the carriage body 10 and the operation tool 30 will be described.
In order to connect the bogie main body 10 and the operation tool 30, first, as shown in FIG. 4, the connection portion 33 of the lifter portion 32 of the operation tool 30 is positioned below the connected portion 15 of the loading portion 10. The attitude (tilt) of the operating rod 31 and the position of the operating tool 30 are adjusted.
Specifically, as shown in FIG. 5A, the operation tool 30 is made to approach the loading section 11 installed on the floor surface FL. At this time, the inclination of the operating rod 31 is adjusted so that the projecting portion 34 of the connecting portion 33 is positioned lower than the lower end surface 15 of the engaged portion 15. As shown in FIG. 4, when the operating rod 31 is supported by the wheel 35 and the arm 36, the projecting portion 34 of the connecting portion 33 is disposed below the lower end surface 15 of the engaged portion 15. It is designed as.

　次いで、図５Ｂに示すように、操作具３０を台車本体１０に近づけて、連結部３３の突出部３４が被係合部１５の貫通孔１５ａの直下に来るように操作する。そして、図５Ｃに示すように、操作竿３１を傾動方向Ａ１に傾斜させていく。傾動方向Ａ１は、図４や図５Ａに示した操作竿３１の傾いた向きとは逆向きである。操作竿３１を傾動方向Ａ１に傾斜させると、連結部３３の突出部３４の位置が上方に移動し、突出部３４の一部が被係合部１５の貫通孔１５ａ内に入り込み、突出部３４が貫通孔１５ａの内周面に当接するとともに連結部３３の上端面３３ａが被係合部１５の下端面１５ｂに当接する。すなわち、連結部３３が被係合部１５に係止する。 Next, as shown in FIG. 5B, the operation tool 30 is brought close to the carriage main body 10, and the projecting portion 34 of the connecting portion 33 is operated to be directly below the through hole 15a of the engaged portion 15. Then, as shown in FIG. 5C, the operating rod 31 is inclined in the tilting direction A1. The tilting direction A1 is opposite to the inclined direction of the operating rod 31 shown in FIGS. 4 and 5A. When the operating rod 31 is inclined in the tilting direction A1, the position of the projecting portion 34 of the connecting portion 33 moves upward, and a part of the projecting portion 34 gets into the through hole 15 a of the engaged portion 15 and the projecting portion 34 Is in contact with the inner peripheral surface of the through hole 15 a and the upper end surface 33 a of the connecting portion 33 is in contact with the lower end surface 15 b of the engaged portion 15. That is, the connecting portion 33 is engaged with the engaged portion 15.

　操作竿３１を傾動方向Ａ１に傾斜させると、図５Ｄに示すように、作業者の操作による操作竿部３１に作用する傾動モーメントが車輪３７を支点として連結部３３の上端面３３ａが係止する被連結部１５の下端面１５ｂを上方へ押し上げる力として作用する。これと同時に、支点としての車輪３５は、貫通孔１５ａの下方位置に向かう方向Ｂ１に移動していく。この「梃作用」により、台車本体１０の支持部１２の下端面１２ｂは、床面ＦＬから上昇し、床面ＦＬと支持部１２の下端面１２ｂとの間にわずかな間隙が形成される。
　操作竿３１を傾動方向Ａ１にさらに傾斜させていくと、図５Ｅに示すように、車輪３５が貫通孔１５ａの下方位置にさらに近づき、車輪３５の支える荷台部１１の荷重が増大していく。操作竿３１に作用する傾動方向Ａ１とは逆向きのモーメントも急激に減少していき、操作者は操作竿３１から反力をほとんど感じなくなる。
　図５Ｆに示すように、車輪３５が貫通孔１５ａの下方位置に到達すると、連結部３３の上端面３３ａに被連結部１５の下端面１５ｂが全面的に接触し、車輪３５が車輪１３と協働して荷台部１１の荷重を支える。これにより、操作竿３１には、傾動方向Ａ１とは逆向きのモーメントが作用しなくなる。このとき、アーム部２６が荷台部１１の底面１１ｂに当接し、操作竿３１の傾動方向Ａ１へのさらなる傾斜が規制される。この結果、台車１は、図１Ａに示した状態となる。この状態においては、連結部３３は、被連結部１５に対して回転可能な状態となる。また、支持部１２の下端面１２ｂと床面ＦＬとの間にはわずかな隙間が形成され、荷台部１１もわずかに傾斜するが、この傾斜は、積載された荷物に影響ない範囲の傾斜である。 When the operating rod 31 is inclined in the tilting direction A1, as shown in FIG. 5D, the tilting moment acting on the operating rod portion 31 by the operation of the operator locks the upper end surface 33a of the connecting portion 33 with the wheel 37 as a fulcrum It acts as a force that pushes up the lower end surface 15b of the coupled portion 15 upward. At the same time, the wheel 35 as a fulcrum moves in the direction B1 toward the lower position of the through hole 15a. By this “wrinkle action”, the lower end surface 12 b of the support portion 12 of the carriage body 10 rises from the floor surface FL, and a slight gap is formed between the floor surface FL and the lower end surface 12 b of the support portion 12.
As the operating rod 31 is further inclined in the tilting direction A1, as shown in FIG. 5E, the wheel 35 further approaches the lower position of the through hole 15a, and the load of the loading platform 11 supported by the wheel 35 increases. The moment in the direction opposite to the tilting direction A1 acting on the operating rod 31 also decreases sharply, and the operator hardly feels any reaction force from the operating rod 31.
As shown in FIG. 5F, when the wheel 35 reaches the lower position of the through hole 15a, the lower end surface 15b of the connected portion 15 is in full contact with the upper end surface 33a of the connecting portion 33, and the wheel 35 cooperates with the wheel 13. Work to support the load of the loading platform 11. As a result, a moment in the reverse direction to the tilting direction A1 does not act on the operating rod 31. At this time, the arm portion 26 abuts on the bottom surface 11 b of the loading portion 11, and the further inclination of the operating rod 31 in the tilting direction A1 is restricted. As a result, the dolly 1 is in the state shown in FIG. 1A. In this state, the connecting portion 33 is rotatable with respect to the connected portion 15. In addition, although a slight gap is formed between the lower end surface 12b of the support portion 12 and the floor surface FL, and the loading portion 11 is slightly inclined, this inclination is an inclination that does not affect the loaded luggage. is there.
