Description

  The present invention relates to a transport cart used for transporting articles.

  Conventionally, when carrying an article such as a cardboard packed with a package, a carrier as disclosed in Patent Document 1 below is used.

Japanese Patent Laid-Open No. 2015-24822

  However, when an article such as cardboard is loaded on the loading platform of the carrier, it is necessary for the operator to manually lift the cardboard or the like and load it on the loading platform, so that the burden on the worker is large.

  Therefore, in the transport cart used for transporting the article, there is a problem that the operator is not burdened when the article is loaded on the transport cart.

  The present invention for solving the above-mentioned problems is a transport cart for transporting an article, comprising two wheels, a horizontal axis unit that extends horizontally and is fixed to the wheel, and the horizontal axis unit A gripping unit extending in the vertical direction from the center of the gripping unit, and a ring-shaped suspension band unit that is fixed to the gripping unit and suspended from the article. It is a transport cart that is in contact with each other and suspends the suspension band unit on a side surface opposite to the one side surface of the article and makes the article tiltable and transportable with the wheel as a fulcrum.

  It is preferable that an anti-slip portion is disposed on at least one of the back surface of the gripping unit and the suspension band unit.

  The gripping unit is preferably extendable and retractable.

  The transport cart according to the present invention includes two wheels, a horizontal axis unit that extends in the horizontal direction and is fixed to the wheel, a gripping unit that extends in the vertical direction from the center of the horizontal axis unit, and a gripping unit. Since it has a ring-shaped suspension band unit that is fixed and suspended on the article, one side of the article is brought into contact with the back surface of the gripping unit, and the suspension unit is suspended on the side opposite to the one side of the article. However, since the article can be tilted according to the lever principle with the wheel as a fulcrum and the article can be lifted and transported easily, it is necessary for the operator to lift the article by human power and load it on the carriage. Therefore, the burden on the worker can be reduced.

  In addition, an anti-slip portion is disposed on at least one of the back surface of the gripping unit and the suspension band unit, so that the suspension band unit is suspended on one side opposite to one side of the article and the wheel is a fulcrum. Thus, when the article is tilted and the article is lifted to be transportable, the suspension unit can be prevented from slipping off the article by the anti-slip portion.

  In addition, since the gripping unit can be expanded and contracted in the extending direction, the length of the gripping unit can be adjusted according to the physique of the worker, so that the gripper can be adjusted to an appropriate length by the worker. By gripping the unit and tilting the article with the wheel as a fulcrum, the article can be lifted more easily and transported.

It is a perspective view which shows an example of the transport cart. It is a side view which shows the state which inclined the article | item with the wheel of the carrier cart as a fulcrum, and lifted the article | item and is in the state which can be conveyed.

  An article 9 shown in FIG. 1 is, for example, a cardboard box sealed with gum tape or the like in a state in which a predetermined amount of luggage is packed therein, and has a substantially rectangular parallelepiped outer shape. The article 9 is not limited to a cardboard box.

  A transport cart 1 for transporting an article 9 shown in FIG. 1 includes two wheels 10, a horizontal axis unit 11 extending in the horizontal direction and fixing the wheels 10, and a vertical direction from the center of the horizontal axis unit 11. At least, and a ring-shaped suspension band unit 13 that is fixed to the holding unit 12 and is suspended from the article 9.

  The horizontal axis unit 11 includes a pedestal 110 in which, for example, an aluminum alloy or the like is formed in a flat plate shape having a rectangular thickness in plan view. The longitudinal direction of the pedestal 110 is the Y-axis direction perpendicular to the horizontal direction in the traveling direction of the transport cart 1 (X-axis direction in FIG. 1). For example, the longitudinal direction length is the longitudinal direction of the article 9. It is preferable that it is longer than the length.

On both sides in the Y-axis direction of the upper surface 110a of the pedestal 110, end-side support portions 111 having a substantially rectangular parallelepiped shape are erected toward the + Z direction side. In addition, at the center of the upper surface 110a of the pedestal 110, two substantially rectangular parallelepiped gripping unit fixing portions 112 are erected toward the + Z direction side. A predetermined gap is provided between the two gripping unit fixing portions 112, and the gripping unit 12 is fixed on the horizontal axis unit 11 while being inserted into the gap. For example, the pedestal 110, the end-side support part 111, and the gripping unit fixing part 112 may be reduced in weight by providing a cavity therein.

  For example, the wheel receiver 101 including the axle 101a is fixed to the front surface 111b of each end-side support portion 111 by a bolt or the like (not shown). The axle 101a has an axis in the Y-axis direction, and the wheel 10 is rotatably mounted on the axle 101a. For example, since the lowermost position of the wheel 10 shown in FIG. 1 and the height position of the bottom surface 110c of the pedestal 110 are substantially the same position, the pedestal 110 can be placed in a state where the transport cart 1 is erected as shown in FIG. When the entire bottom surface 110c comes into contact with a floor surface (not shown), the transport cart 1 can continue stably without falling down.

  The gripping unit 12 includes, for example, a gripping part 120 gripped by an operator when moving the transport cart 1 loaded with an article 9, and a suspension band holding part 121 removably attached to the front surface 120b of the gripping part 120. A grip part auxiliary extension part 122 is provided on the upper side of the grip part 120 so as to be detachably attached.

  For example, the grip portion 120 is formed of an aluminum alloy or the like in a rectangular column shape having a predetermined length, and in the illustrated example, a single groove 120m is formed from the front surface 120b to the upper surface 120a. In addition, the holding part 120 may not be formed with the groove 120m. The grip portion 120 is fixed to the horizontal axis unit 11 so as to extend in the vertical direction from the central portion of the horizontal axis unit 11 with the front surface 120b facing the wheel 10 side (the −X direction side in FIG. 1). The Specifically, for example, a bolt insertion hole (not shown) penetrating from the + Y direction side to the −Y direction side is formed in the lower portion of the grip portion 120. Also, in one gripping unit fixing portion 112, a bolt insertion hole 112g is provided in the Y-axis direction at a position corresponding to a bolt insertion hole (not shown) of the gripping portion 120 in a state of being inserted into a gap between the two gripping unit fixing portions 112. A female screw hole (not shown) is formed in the other gripping unit fixing portion 112 so as to penetrate therethrough. The gripping part 120 is inserted into the gap between the two gripping unit fixing parts 112, and the bolt insertion holes 112g and female screw holes of the gripping unit fixing part 112 and the bolt insertion holes (not shown) of the gripping part 120 are overlapped with each other via a washer or the like. Then, the bolts 112j are threaded into the female screw holes through the bolt insertion holes 112g, so that the grip 120 is laterally extended from the central portion of the horizontal axis unit 11 as shown in FIG. It can be fixed on the shaft unit 11. The fixing of the grip part 120 to the horizontal axis unit 11 is not limited to the present embodiment, and the grip unit 120 may not be provided, and the grip part 120 may be fixed to the upper surface 110a of the pedestal 110 with a bolt or the like. Good.

  For example, in FIG. 1, the front surface 110 b of the pedestal 110 facing the −X direction side, the front surface 111 b of each end-side support portion 111, the front surface 112 b of each gripping unit fixing portion 112, and the front surface 120 b of the gripping portion 120 Is, for example, flush.

  On the groove 120m formed on the front surface 120b of the grip portion 120, there are a plurality (for example, three in the example shown in the figure, with a certain interval in the extending direction (Z-axis direction) of the groove 120m. A suspension band attachment hole 120f (not shown) is formed so as to pierce toward the inside of the grip part 120.

  The suspension band holding part 121 having a rod-like outer shape is a mounting pin that fits into the suspension band holding part mounting hole 120f if the suspension band holding part mounting hole 120f formed on the front surface 120b of the grip part 120 is a fitting hole. In the case where the suspension band holding portion mounting hole 120f is a screw hole, the screw is provided with a screw groove on the side surface of the lower end portion and screwed into the suspension band holding portion mounting hole 120f. In the illustrated example, the suspension band holding part 121 is attached so as to be orthogonal to the grip part 120 only in one of the three suspension band holding part attachment holes 120f. The suspension band holding part 121 may be attached to all of the holes 120f. At the upper end side (the −X direction side end in FIG. 1) of the suspension band holding part 121, for example, a flange-like dropout prevention part 121 a that extends toward the radial outside of the suspension band holding part 121 is formed. The prevention unit 121 a prevents the suspension band unit 13 fixed to the suspension band holding unit 121 from falling off the suspension band holding unit 121.

  On the lower side of the back surface 120d of the grip portion 120 of the grip unit 12, for example, a non-slip seal (not shown) made of a base resin or a rubber resin into which fine particles are kneaded to provide friction resistance is provided. It may be stuck as a part. The anti-slip seal may be attached to the back surface 112d of each gripping unit fixing portion 112 and the back surface 111d of the end-side support portion 111.

  In this embodiment, the gripping part auxiliary extension part 122 is formed in a rectangular columnar frame shape, and has a rectangular cross section corresponding to the square columnar outer shape of the gripping part 120 in order to insert the gripping part 120. A hole 122g is formed. The cross-sectional width of the insertion hole 122g is slightly larger than the cross-sectional width of the grip portion 120. Further, a stopper insertion hole 122h is formed through the lower portion of the side surface 122c (the surface on the Y-axis direction side in FIG. 1) of the grip portion auxiliary extension portion 122 from the side surface 122c to the side surface opposite to the side surface 122c. .

  From the middle part to the upper part of the side surface 120c (the surface on the Y-axis direction side in FIG. 1) of the grip portion 120, a fitting hole 120h is formed penetrating from the side surface 120c to the side surface opposite to the side surface 120c. In the illustrated example, for example, the fitting holes 120h are formed in a plurality (for example, five in the illustrated example) at regular intervals in the Z-axis direction. The grip portion 120 is inserted into the insertion hole 122g of the grip portion auxiliary extension portion 122, and one of the five fitting holes 120h of the grip portion 120 and the stopper insertion hole 122h of the grip portion auxiliary extension portion 122 are overlapped. By inserting the pin-shaped stopper 122j into the stopper 122h and the fitting hole 120h, the grip portion auxiliary extension portion 122 can be connected to the grip portion 120. The through-hole 122f formed in the front surface 122b of the grip portion auxiliary extension portion 122 allows the suspension band holding portion 121 to be inserted into the grip portion auxiliary extension portion 122 when the grip portion auxiliary extension portion 122 is attached to the grip portion 120. It is an insertion hole for.

  Note that the mounting of the grip portion auxiliary extension portion 122 to the grip portion 120 is not limited to that performed by the pin-shaped stopper 122j. For example, the fitting hole 120h is a screw hole, the stopper 122j is a bolt, and the bolt is It is good also as what is made by screwing in the fitting hole 120h. Alternatively, instead of the fitting hole 120h, a push-type movable rivet including a spring or the like is disposed at a predetermined height position corresponding to each fitting hole 120h on the side surface 120c of the holding part 120, so that the holding part 120 is When the gripping part auxiliary extension part 122 is inserted into the gripping part auxiliary extension part 122, the gripping part auxiliary extension part 122 is attached to the gripping part 120 by fitting the movable rivet into the stopper insertion hole 122h of the gripping part auxiliary extension part 122 from the inside of the insertion hole 122g. It is good also as what is done.

  The suspension band unit 13 is formed of a high-strength polyester fiber, nylon fiber or the like, for example, a suspension band 130 that is a long band having a uniform lateral width, and the suspension band 130 is inserted into the suspension band 130 to form a ring shape. The suspension part 130b is formed, and an adjuster 131 capable of adjusting the size of the ring-like suspension part 130b, and a non-slip portion 132 attached to the suspension part 130b are provided.

  As shown in FIG. 1, the suspension band 130 is inserted through an adjuster 131 having a drawer shaft and the like, and adjusts the size of the annular suspension part 130 b suspended from the article 9 and the annular suspension part 130 b. In this case, it is divided into a long size adjusting portion 130c that is pulled out from the adjuster 131. The anti-slip portion 132 has, for example, a belt-like outer shape wider than the suspension belt 130, and is made of a synthetic resin such as polyvinyl chloride or a synthetic rubber. The back surface 132 b of the anti-slip portion 132 is a surface that comes into contact with the article 9. Further, an insertion hole 132 c through which the suspension band 130 is inserted is formed on the surface 132 a of the anti-slip part 132 in the extending direction of the anti-slip part 132.

  For example, a hook member 133 that can be hooked to the suspension band holding portion 121 is attached to the ring-shaped suspension portion 130b, and the hook unit 133 is hooked to the suspension band holding portion 121, so The unit 13 can be fixed. The hook unit 133 is sandwiched between the brim-shaped drop-off preventing part 121a of the suspension band holding part 121 and the front surface 120b of the gripping part 120 so that the suspension band unit 13 is more firmly fixed to the gripping unit 12. Also good. Alternatively, the hook member 133 may not be provided, and the suspension band unit 13 may be fixed to the gripping unit 12 by directly hooking a part of the ring-shaped suspension portion 130 b to the suspension band holding portion 121.

  Below, the usage method of the transport cart 1 in the case of transporting the article 9 by the transport cart 1 shown in FIG. 1 will be described. First, the worker brings the transport cart 1 close to the article 9 and makes one side 9b (the side on the + X direction side in FIG. 1) of the article 9 abut on the lower part of the back surface 120d of the holding unit 120 of the holding unit 12. In the present embodiment, at the same time, one side surface 9 b of the article 9 is also in contact with the back surface 112 d of the gripping unit fixing portion 112 and the back surface 111 d of the end-side support portion 111.

  For example, when the height of the worker who uses the transport cart 1 is high, the entire length of the gripping unit 12 is maximized. That is, the fitting hole 120h located at the top of the grip part 120 and the stopper insertion hole 122h of the grip part auxiliary extension part 122 are overlapped to make the pin-shaped stopper 122j into the stopper insertion hole 122h and the fitting hole 120h. Insert it. By doing so, the length of the grip portion auxiliary extension portion 122 is added to the length of the grip portion 120 of the grip unit 12, and the grip portion 120 is extended to a length that is easy for the operator to work. it can.

  Next, the ring-shaped suspension part 130b of the suspension band 130 of the suspension band unit 13 is suspended from the one side surface 9b of the article 9 and the side surface 9d opposite to the side surface 9d. That is, for example, first, the suspension band 130 is pulled from the adjuster 131 toward the suspension portion 130 b by a predetermined length, and the ring-shaped suspension portion 130 b is set to be slightly larger than the entire size of the article 9. Then, the ring-shaped suspension portion 130b of the suspension band 130 is suspended from the side surface 9d of the article 9, and the ring-shaped suspension of the suspension band 130 is also performed on both side surfaces 9c in the Y-axis direction of the article 9 shown in FIG. The suspension band 130 is aligned with the article 9 so that the portion 130b abuts. Next, the size adjusting portion 130c is pulled from the adjuster 131 by a predetermined length, the diameter of the annular suspension portion 130b is reduced, and the article 9 is supported from the three directions of the side surfaces 9d and 9c by the suspension portion 130b of the suspension band 130. . And the suspension part 130b will be in the tension | tensile state without slack.

  When the suspended portion 130b suspended from the article 9 is stretched, the back surface 132b of the anti-slip portion 132 comes into contact with, for example, the side surfaces 9d and 9c of the article 9. As a result, it is possible to generate a frictional force that prevents the suspension band 130 from being displaced between the back surface 132b of the anti-slip portion 132 and the side surfaces 9d and 9c of the article 9.

  Next, the operator grips the grip part 120 or the grip part auxiliary extension part 122 and pulls down the grip unit 12 in the direction of the arrow R as shown in FIG. As a result, the article 9 can be tilted according to the lever principle with the wheel 10 in contact with the ground G as a fulcrum, and the article 9 can be easily lifted and transported. Then, when the operator pulls the grip part 120 or the grip part auxiliary extension part 122 in the −X direction, it is carried by the back surface 120d of the grip part 120, the back surface 111d of the end support part 111, and the suspension band. The article 9 in which the side surfaces 9 d and 9 c are supported by the suspended portion 130 b of 130 can be transported by the transport cart 1. When a non-slip seal (not shown) is attached as a non-slip part to the lower part of the back surface 120d of the grip unit 120 of the grip unit 12, slipping occurs due to gravity from the article 9 to the back surface 120d of the grip part 120. A frictional force sufficient to prevent the suspension band 130 from being displaced can be generated between the stop seal and the one side surface 9 b of the article 9.

  The transport cart 1 according to the present invention includes two wheels 10, a horizontal axis unit 11 that extends in the horizontal direction and to which the wheels 10 are fixed, and a gripping unit that extends in the vertical direction from the center of the horizontal axis unit 11. 12 and a ring-shaped suspension band unit 13 fixed to the gripping unit 12 and suspended on the article 9, one side surface 9 b of the article 9 is brought into contact with the back surface 120 d of the gripping unit 12, and the suspension band unit 13 is suspended on one side 9d opposite to the side 9b of the article 9, and the article 9 can be lifted and transported easily by tilting the article 9 according to the lever principle with the wheel 10 in contact with the ground G as a fulcrum. Therefore, it is not necessary for the operator to lift up the article with only human power and load it on the transport carriage, and the burden on the operator can be reduced. Further, since the transport cart 1 can be stored in a storage place in a self-supporting state, the storage space is not occupied widely.

  Further, an anti-slip portion (in this embodiment, an anti-slip portion 132 attached to the suspension band unit 13) is disposed on at least one of the back surface 120d of the gripping unit 12 and the suspension band unit 13. Then, when the suspension band unit 13 is suspended on the side surface 9d opposite to the one side surface 9b of the article 9, and the article 9 is inclined with the wheel 10 as a fulcrum, the article 9 is lifted to be transportable. It is possible to prevent the suspension band unit 13 from sliding off the article 9 by the anti-slip portion 132.

  Further, by providing the gripping unit 12 with, for example, a gripping portion auxiliary extending portion 122, the length of the gripping unit 12 can be adjusted according to the physique of the operator, etc. Therefore, the operator can hold the grip unit 12 adjusted to an appropriate length, tilt the article 9 with the wheel 10 as a fulcrum, and lift the article 9 more easily into a transportable state.

  The transport cart 1 according to the present invention is not limited to the present embodiment, and the configuration and shape of the transport cart 1 illustrated in the accompanying drawings are not limited thereto. Modifications can be made as appropriate within a range where the effects of the present invention can be exhibited.
