"Folding cart" according to Japanese Patent Application Laid-Open No. 2002-1778928 "Hand cart" according to JP 2001-287654 A

このように折畳み式台車にも色々な形態があるが、折畳むことでコンパクト化するだけでなく、折畳み操作が簡単であることが必要となる。本発明が解決しようとする課題はこれら問題点であり、持ち上げることなく荷台を折畳むことが出来ると共に、折畳まれた状態でもキャスタにて移動でき、しかもハンドルを縮めることが可能な折畳み式台車を提供する。   As described above, there are various types of folding carts, but it is necessary not only to make them compact by folding them but also to make the folding operation simple. The problems to be solved by the present invention are these problems, and a folding cart that can be folded without being lifted, can be moved by a caster even in a folded state, and the handle can be shortened. I will provide a.

本発明に係る折畳み式台車は荷台と門形ハンドル、及び4個のキャスタを有しており、上記荷台は2つ折りされる。そして、門形ハンドルも中立軸を中心として2つ折りすることが出来る。上記荷台は継手を介して折畳まれる左右の荷台板を有し、各荷台板の両側端は軸を介して基台と連結している。基台の下側前後端部には上記キャスタが取付けられている。   The folding cart according to the present invention has a loading platform, a gate handle, and four casters, and the loading platform is folded in two. The portal handle can be folded in two with the neutral axis as the center. The loading platform has left and right loading platform plates that are folded via joints, and both ends of each loading platform plate are connected to the base via a shaft. The casters are attached to the lower front and rear ends of the base.

そして、両基台の手前側後方端には上記ハンドルの両脚が取付けられる。又、基台から起立する支柱に脚が嵌って取付けられる。キャスタは基台に取付けられる為に、荷台板の折畳み動作に伴って転倒することはない。ハンドルは中立軸を中心として2つ折りされるが、両基台はハンドルの両脚と共に距離が縮小して折畳まれる。ハンドルには折畳み防止機構が備わり、折畳み防止機構を解除しない限り、ハンドル及び荷台板が折畳まれないように成っている。   And the both legs of the said handle | steering-wheel are attached to the near rear end of both bases. In addition, the legs are fitted and attached to a support column standing up from the base. Since the caster is attached to the base, the caster does not fall over with the folding operation of the carrier plate. The handle is folded in two with the neutral axis as the center, but both bases are folded at a reduced distance with the legs of the handle. The handle is provided with a folding prevention mechanism so that the handle and the carrier plate are not folded unless the folding prevention mechanism is released.

そして、門形ハンドルは上記基台に固定されて該基台から起立する支柱に嵌って取付けすることが出来るが、ハンドル脚は該支柱に嵌ってスライド可能となっている。従って、ハンドルの高さは縮小される。しかも、このハンドル脚にもロック機構が設けられて通常は縮小しないようにロックされる。   The portal handle is fixed to the base and can be fitted to and attached to a column that stands up from the base, but the handle leg is slidable by fitting to the column. Therefore, the height of the handle is reduced. Moreover, this handle leg is also provided with a lock mechanism and is normally locked so as not to shrink.

本発明に係る台車はその荷台に荷物を載せて運ぶことが出来る。これは従来の台車と同じであるが、本発明の折畳み式台車は荷台及びハンドルを2つ折りすることが出来、使用しないときにはコンパクトに折畳んで収納できる。この場合、台車を持ち上げることなく4個のキャスタが床面(地面)に着いたままの状態で折畳まれ、同時にハンドルも荷台の折畳み動作に伴って2つ折りされる。そしてハンドルはその高さを縮小することが出来る。本発明の台車はその折畳み操作が簡単であり、容易である。   The cart according to the present invention can carry a load on the loading platform. This is the same as the conventional cart, but the folding cart of the present invention can fold the loading platform and the handle in two, and can be folded and stored compactly when not in use. In this case, the four casters are folded while they are on the floor (ground) without lifting the carriage, and at the same time, the handle is folded in two with the folding operation of the loading platform. And the handle can reduce its height. The cart of the present invention is simple and easy to fold.

図1は本発明に係る折畳み式台車を表している外観図である。同図の1は荷台、2はハンドル、3は前方キャスタ、4は後方キャスタ、5は支柱をそれぞれ示している。台車としての基本構造は従来と同じであり、上記荷台1には荷物を載せ、ハンドル2を握って移動することが出来る。荷台1の下側に取付けた前方キャスタ3,3はその向きを変えることが出来る為に、台車は任意の方向へ自由に動くことが出来る。   FIG. 1 is an external view showing a folding cart according to the present invention. In the figure, 1 is a loading platform, 2 is a handle, 3 is a front caster, 4 is a rear caster, and 5 is a support column. The basic structure as a cart is the same as the conventional one, and a load can be placed on the loading platform 1 and the handle 2 can be held and moved. Since the front casters 3 and 3 attached to the lower side of the loading platform 1 can change their directions, the cart can freely move in any direction.

ところで、本発明に係る台車は折畳み式であり、荷台1は2枚の荷台板6a,6bから成り、両荷台板6a,6bは蝶番などの継手を介して折畳みすることが出来るように連結されている。しかも、荷台1はその中央部が上昇して2つ折り出来る継手構造となっている。この場合、前方キャスタ3,3、及び後方キャスタ4,4は倒れないような構造としている。   By the way, the cart according to the present invention is a folding type, and the loading platform 1 is composed of two loading platform plates 6a and 6b, and both loading platform plates 6a and 6b are connected so as to be folded via a joint such as a hinge. ing. In addition, the loading platform 1 has a joint structure that can be folded in two by raising its central portion. In this case, the front casters 3 and 3 and the rear casters 4 and 4 are configured not to fall down.

上記荷台1は蝶番などの継手を介して折畳み出来るように成っている2枚の荷台板6a,6bを有しているが、前方キャスタ3,3、及び後方キャスタ4,4は荷台板6a,6bに直接取着されず、基台7a,7bに取付けられている。基台7aの前後端には支持部8a,8aが固定され、この支持部8a,8aに設けた軸9a,9aを介して荷台板6aが回転可能に軸支されている。同じく、基台7bの前後端には支持部8b,8bが固定され、この支持部8b,8bに設けた軸9b,9bを介して荷台板6bが回転可能に軸支されている。   The loading platform 1 has two loading platform plates 6a and 6b which can be folded via a joint such as a hinge, but the front casters 3 and 3 and the rear casters 4 and 4 are loaded with the loading platform plate 6a, It is not directly attached to 6b but is attached to the bases 7a and 7b. Support portions 8a and 8a are fixed to the front and rear ends of the base 7a, and a cargo bed plate 6a is rotatably supported via shafts 9a and 9a provided on the support portions 8a and 8a. Similarly, support portions 8b and 8b are fixed to the front and rear ends of the base 7b, and the loading plate 6b is rotatably supported via shafts 9b and 9b provided on the support portions 8b and 8b.

そして、基台7aの後方端には上記支柱5aが起立し、基台7bの後方端にも支柱5bが起立している。この支柱5a,5bは中空パイプで構成されて、上記ハンドル2の両脚10a,10bが嵌っている。ハンドル2は両脚10a,10bと持ち手部11a,11bを有した概略門形をしている。両持ち手部11a,11bは中立に設けた軸を介して互いに連結し、2つ折りすることが出来る。   The support column 5a stands on the rear end of the base 7a, and the support column 5b stands on the rear end of the base 7b. These struts 5a and 5b are formed of hollow pipes, and both legs 10a and 10b of the handle 2 are fitted therein. The handle 2 has a substantially portal shape having both legs 10a and 10b and handle portions 11a and 11b. Both the handle portions 11a and 11b can be connected to each other via a neutral shaft and can be folded in two.

ところで、図1に示す台車は荷台1とハンドル2が2つ折りされて図2のように折畳まれる。荷台1の中央が上昇して両荷台板6a,6bは垂直に起立し、両基台7a,7bの間隔は縮小される。基台7a,7bは折畳み操作に際してその向きを変えることなく、間隔が縮小するだけとなり、その為に前方キャスタ3,3、及び後方キャスタ4,4はそのまま地面上を転動することが出来る。   By the way, the cart shown in FIG. 1 is folded as shown in FIG. As the center of the loading platform 1 rises, both loading platform plates 6a and 6b stand vertically, and the distance between the both platforms 7a and 7b is reduced. The bases 7a and 7b do not change their orientation during the folding operation, but only the distance is reduced. Therefore, the front casters 3 and 3 and the rear casters 4 and 4 can roll on the ground as they are.

すなわち、荷台板6aは基台7aの前後端に固定した支持板8a,8aに軸9a,9aを介して軸支され、荷台板6bは基台7bの前後端に固定した支持板8b,8bに軸9b,9bを介して軸支されている。そして、荷台板6aの底の前後端部には底梁12a,12aが取着され、同じく荷台板6bの底の前後端部には底梁12b,12bが取着されている。該底梁12a,12bはその中央側に形成した継手部13aと13bが軸14を介して連結している。   That is, the cargo bed plate 6a is pivotally supported on the support plates 8a and 8a fixed to the front and rear ends of the base 7a via the shafts 9a and 9a, and the load bed plate 6b is supported on the front and rear ends of the base 7b. Are supported by shafts 9b and 9b. The bottom beams 12a and 12a are attached to the front and rear end portions of the bottom of the loading plate 6a, and the bottom beams 12b and 12b are attached to the front and rear ends of the bottom of the loading plate 6b. The bottom beams 12 a and 12 b are connected to each other through joints 13 a and 13 b formed on the center side thereof.

図3は本発明に係る折畳み式台車の正面図であり、(a)は荷台板6a,6bが水平に開いた状態、(b)は荷台板6a,6bが垂直折畳まれた状態を表している。荷台板6aの底には底梁12aが固定され、荷台板6bの底には底梁12bが固定されている。そして、両底梁12a,12bは中央側にて軸14を介して連結されていて、(b)に示すように折畳むことが出来る。荷台板6a,6bの折畳み動作に際して、荷台板6aは軸9aに軸支されて回転し、荷台板6bは軸9bに軸支されて回転することが出来る。   3A and 3B are front views of the folding cart according to the present invention, in which FIG. 3A shows a state in which the carrier plates 6a and 6b are opened horizontally, and FIG. 3B shows a state in which the carrier plates 6a and 6b are folded vertically. ing. A bottom beam 12a is fixed to the bottom of the loading plate 6a, and a bottom beam 12b is fixed to the bottom of the loading plate 6b. The bottom beams 12a and 12b are connected to each other via a shaft 14 on the center side, and can be folded as shown in FIG. In the folding operation of the loading platform plates 6a and 6b, the loading platform plate 6a can be pivotally supported by the shaft 9a, and the loading platform plate 6b can be supported by the shaft 9b and can be rotated.

両荷台板6a,6bは図3(b)のように中央側が上昇して折畳まれるが、(a)
の水平状態から中央側が降下することはない。すなわち、重い荷物を載せることが出来るようになっている。荷台板6aの中央側には当接部15aが設けられ、荷台板6bの中央側には当接部15bが設けられていて、荷台板6a,6bが水平状態に開いた状態で両当接部15a,15bは互いに当接している。
Both loading platform plates 6a and 6b are folded with the central side rising as shown in FIG. 3 (b).
The center side does not descend from the horizontal state. In other words, heavy loads can be loaded. An abutment portion 15a is provided on the center side of the carrier plate 6a, and an abutment portion 15b is provided on the center side of the cargo plate 6b, so that the abutment plates 6a and 6b are both in contact with each other in the horizontal state. The parts 15a and 15b are in contact with each other.

図3から明らかなように、本発明に係る折畳み台車は、荷台板6a,6bが折畳まれても基台7a,7bが折畳まれることはなく、その為に該基台7a,7bに取着されている前方キャスタ3,3、及び後方キャスタ4,4はそのままの状態で起立している。そして、ハンドル2も荷台板6a,6bと共に2つ折りされる。   As is apparent from FIG. 3, the folding cart according to the present invention does not fold the bases 7a and 7b even when the carrier plates 6a and 6b are folded. Therefore, the bases 7a and 7b are not folded. The front casters 3 and 3 and the rear casters 4 and 4 attached to the rear stand upright as they are. And the handle | steering-wheel 2 is also folded in two with the carrier board 6a, 6b.

ハンドル2はその構造が左右に2分割されて2つ折りされるが、脚10aの上部に形成している持ち手部11aと脚10bの上部に形成している持ち手部11bが互いに連結されている。左側の持ち手部11aには上継手片16aと下継手片17aが固定され、右側の持ち手部11bには上継手片16aと下継手片17bが固定されている。そして上継手片16a,16b、及び下継手片17a,17bは軸を介して互いに連結され、ハンドル2は該軸を中心として折畳まれる。   The handle 2 is divided into two parts, right and left, and is folded in two. The handle portion 11a formed on the upper portion of the leg 10a and the handle portion 11b formed on the upper portion of the leg 10b are connected to each other. Yes. An upper joint piece 16a and a lower joint piece 17a are fixed to the left handle portion 11a, and an upper joint piece 16a and a lower joint piece 17b are fixed to the right handle portion 11b. The upper joint pieces 16a and 16b and the lower joint pieces 17a and 17b are connected to each other via a shaft, and the handle 2 is folded around the shaft.

図4はハンドル2の持ち手部11a,11bの連結構造を示している具体例であり、上継手片16a,16bと下継手片17a,17bは軸18にて連結されている。そして、持ち手部11aに取着した支持部20にはストッパーピン19が取付けられ、該ストッパーピン19の上端は上継手片16aに設けた穴を貫通し、さらに上継手片16bに設けた穴に嵌っている。ストッパーピン19にはコイルバネ21が取付けられ、このコイルバネ21のバネ力が付勢されて上方へ突出し、上継手片16a,16bに設けた穴から外れないようにしている。   FIG. 4 is a specific example showing the connection structure of the handle portions 11 a and 11 b of the handle 2, and the upper joint pieces 16 a and 16 b and the lower joint pieces 17 a and 17 b are connected by a shaft 18. A stopper pin 19 is attached to the support portion 20 attached to the handle portion 11a, and the upper end of the stopper pin 19 passes through a hole provided in the upper joint piece 16a, and further, a hole provided in the upper joint piece 16b. It fits in. A coil spring 21 is attached to the stopper pin 19, and the spring force of the coil spring 21 is urged to protrude upward so as not to be removed from the holes provided in the upper joint pieces 16 a and 16 b.

左右の持ち手部11a,11bは軸18を中心として回転して2つ折りされるが、該軸18から離れた位置に設けた穴にストッパーピン19が嵌ることでハンドル2の折畳み動作は防止される。ハンドル2を折畳む場合にはストッパーピン19を上方から押圧して上継手片16bの穴から外した状態で行うことが出来る。そして、折畳まれているハンドル2を元の状態に開く際には、上継手片16bが回転して所定の位置に来たところでストッパーピン19の先端は穴に嵌ることが出来る。すなわち、コイルバネ21のバネ力が常に作用してストッパーピン19を押し上げている。   The left and right handle parts 11a and 11b rotate about the shaft 18 and are folded in two. However, the stopper pin 19 is fitted in a hole provided at a position away from the shaft 18, and the folding operation of the handle 2 is prevented. The When the handle 2 is folded, the stopper pin 19 can be pressed from above and removed from the hole of the upper joint piece 16b. When the folded handle 2 is opened to the original state, the tip of the stopper pin 19 can be fitted into the hole when the upper joint piece 16b rotates and reaches a predetermined position. That is, the spring force of the coil spring 21 always acts to push up the stopper pin 19.

図5はハンドル2の脚10のロック機構を表している具体例である。支柱5には脚10が嵌っていて、持ち手部11を押し下げる為に脚10は下方向にスライドすることが出来、しかもハンドル2を2つ折りする為に回転することが出来る構造としている。しかし、スライド及び回転が常に自由に出来たのではハンドル2が安定しない為に、ロック機構が備わっている。   FIG. 5 is a specific example showing a locking mechanism of the leg 10 of the handle 2. A leg 10 is fitted to the column 5, and the leg 10 can be slid downward to push down the handle 11, and can be rotated to fold the handle 2 in half. However, since the handle 2 is not stable if the slide and rotation are always free, a lock mechanism is provided.

脚10の下端には内芯22が嵌っていて、この内芯22の上端部には水平方向に設けた収容穴23が貫通して設けられ、該収容穴23にはコイルバネ24を収容している。そして支柱5の上端には外輪26が嵌って取付けられ、この外輪26の穴30には脚10が嵌っている。すなわち、外輪26は支柱5と脚10の境界部位に取付けられている。   An inner core 22 is fitted to the lower end of the leg 10, and a receiving hole 23 provided in a horizontal direction is provided through the upper end portion of the inner core 22, and a coil spring 24 is received in the receiving hole 23. Yes. An outer ring 26 is fitted and attached to the upper end of the column 5, and a leg 10 is fitted in a hole 30 of the outer ring 26. That is, the outer ring 26 is attached to the boundary portion between the support column 5 and the leg 10.

そして、外輪26の穴30には降下部位27,27が対称位置に設けられ、両降下部位27,27は同じ高さに形成されるリング溝28,28にて連続している。ところで、該降下部位27,27にはピン25,25が嵌り、収容穴23に収容されているコイルバネ24のバネ力が付勢されて両ピン25,25を外方向へ押圧して降下部位27,27に位置している。ここで、該ピン25,25は脚10に設けた穴に嵌合した状態で降下部位27,27に係合している。   The lowering portions 27 and 27 are provided at symmetrical positions in the hole 30 of the outer ring 26, and both the lowering portions 27 and 27 are continuous with ring grooves 28 and 28 formed at the same height. By the way, the pins 25 and 25 are fitted into the descending portions 27 and 27, and the spring force of the coil spring 24 accommodated in the accommodating hole 23 is urged to press both the pins 25 and 25 outwardly to thereby descend the descending portion 27. , 27. Here, the pins 25, 25 are engaged with the descending portions 27, 27 in a state of being fitted into holes provided in the legs 10.

該降下部位27,27には傾斜面29,29を設けて穴30に嵌っている支柱5の内面と連続している。従って、同図に示す状態で脚10を下方へ押圧するならば、ピン25,25は降下部位27,27から外れて傾斜面29,29を通り、支柱5へ導かれる。すなわち、同図に示す脚10の位置はハンドル2を2つ折りした場合であり、ハンドル2の持ち手部11を押し下げることが出来る。   The descending portions 27 and 27 are provided with inclined surfaces 29 and 29 so as to be continuous with the inner surface of the column 5 fitted in the hole 30. Therefore, if the leg 10 is pressed downward in the state shown in the figure, the pins 25, 25 are removed from the descending portions 27, 27 and are guided to the column 5 through the inclined surfaces 29, 29. That is, the position of the leg 10 shown in the figure is the case where the handle 2 is folded in half, and the handle portion 11 of the handle 2 can be pushed down.

ハンドル2が開いている状態、すなわち図3(a)の状態では持ち手部11が降下してはならない訳で、ピン25,25は降下部位27,27でないリング溝28,28に係合している。このリング溝28,28には上記傾斜面29,29を設けていない為に、持ち手部11を下方へ押圧しても脚10がスライドして降下することはない。すなわち、ピン25,25は外輪26のリング溝28,28に係合していると共に、脚10の穴に嵌っているために、該ピン25,25がリング溝28,28から外れない限り脚10は降下できない。   In the state where the handle 2 is open, that is, in the state shown in FIG. 3A, the handle portion 11 should not be lowered, so that the pins 25 and 25 are engaged with the ring grooves 28 and 28 which are not the lowered portions 27 and 27. ing. Since the inclined surfaces 29, 29 are not provided in the ring grooves 28, 28, the leg 10 does not slide down even if the handle portion 11 is pressed downward. That is, since the pins 25 and 25 are engaged with the ring grooves 28 and 28 of the outer ring 26 and are fitted in the holes of the legs 10, the pins 25 and 25 are not legged unless the pins 25 and 25 are removed from the ring grooves 28 and 28. 10 cannot descend.

ハンドル2が2つ折りされる場合には、脚10の回転と共にピン25,25はリング溝28,28に沿って移動し、降下部位27,27に位置する。降下部位27,27にはその下側に上記傾斜面29,29を形成している為に、持ち手部11を下方へ押圧するならばピン25,25はリング溝28,28から外れて降下し、脚10は下方へスライドする。   When the handle 2 is folded in half, the pins 25, 25 move along the ring grooves 28, 28 along with the rotation of the leg 10, and are positioned at the lowered portions 27, 27. Since the inclined portions 29, 29 are formed on the lower portions 27, 27, the pins 25, 25 are lowered from the ring grooves 28, 28 if the handle portion 11 is pressed downward. The leg 10 slides downward.

ところで、台車を折畳む場合、ハンドル2の持ち手部11に設けたロック機構を解除して2つ折りすることで、基台7a,7bが内側へ移動して荷台板6a,6bが折畳まれる。本発明では荷台板6a,6bが折畳まれ易いように、該荷台板6a,6bを持ち上げるペダルを取付けている。該ペダルは基台7の後端に取着されて足を掛けて押すことで、テコの原理を利用して荷台板6a,6bが持ち上がって折畳まれる構造としている。   By the way, when folding the carriage, by releasing the lock mechanism provided on the handle 11 of the handle 2 and folding it in two, the bases 7a and 7b move inward and the carrier plates 6a and 6b are folded. It is. In the present invention, pedals for lifting the carrier plates 6a and 6b are attached so that the carrier plates 6a and 6b can be easily folded. The pedal is attached to the rear end of the base 7 and has a structure in which the cargo bed plates 6a and 6b are lifted and folded by utilizing the lever principle by pushing and placing the foot.
