Description

  The present invention relates to a hand cart that transports a transported item such as a gaming machine by hand.

  Game machines and mandarin orange boxes that are heavy and bulky are generally carried on a carriage. For example, there are roughly two types of gaming machines, a pachinko gaming machine and a pachislot gaming machine (rotating-type gaming machine). These gaming machines are 810 cm high and weigh several tens of kilograms per unit. (Pachislot machines are heavier than pachinko machines), and when they are installed in amusement halls for replacement or maintenance, they are transported using a four-wheeled carriage due to their weight.

  In recent years, these gaming machines are equipped with electronic devices such as large-sized liquid crystal display devices, and many decorated ones have gained popularity, and accordingly, the weight of gaming machines is heavier than before. It is becoming. However, when a gaming machine is transported by a carriage as in the past, the gaming machine must be lifted and placed on a mounting table, and the lifting work requires a lot of labor and the workability is poor. There is a point. In particular, those who are weak, such as women and the elderly, will be forced to do harsh work, especially.

  Therefore, in Patent Document 1, in order to improve the workability of placing the gaming machine on the mounting table, a concave long groove is provided on the upper surface of the mounting table so that the lower part of the gaming machine fits in a standing state, and a roller is provided in the concave long groove. After a game machine is lifted up and placed on a roller, a transport cart has been proposed in which the other side of the game machine is lifted off the floor surface and the game machine is pulled directly into the concave groove.

The hand cart 1 of the present invention is for carrying a transported item such as a gaming machine by hand. In the following description, the transported material is described as a gaming machine (pachinko gaming machine, pachislot gaming machine), but the transported material is not limited to this.

  As shown in FIGS. 1 and 2, the hand cart 1 has a cart body 2 having a rectangular frame shape, and a lower unit 3 is attached to the lower part of the cart body 2 and a handle 4 is attached to the upper part. The cart body 2 has a cylindrical horizontal pipe 5 that is horizontally provided on the upper end and a cylindrical vertical pipe 6 that is vertically extended downward from both left and right ends of the horizontal pipe 5. A rectangular upper horizontal plate 7 and a middle horizontal plate 8 are installed between the two vertical pipes 6 and 6.

  A handle 4 is provided at both left and right ends of the horizontal pipe 5 so as to extend upward from the vertical pipe 6, and an upper portion of the handle 4 is formed to be bent substantially rearward to the left and right so that it can be easily grasped by a human hand. The lower end of the vertical pipe 6 is connected to the upper plate 10 of the lower unit 3. The lower unit 3 has a horizontal upper plate 10 and a front plate 11 that is suspended downward from the front end of the upper plate 10, and the upper plate 10 and the front plate 11 form a substantially inverted L shape. . The front plate 11 has a substantially semi-circular window 12 formed in an upper portion thereof, and a support plate 13 that supports a side surface of a transported object (game machine) projects forward of the front plate 11 below the window 12. It is provided to do. The support plate 13 is formed in a rectangular plate shape and is connected to the front plate 11 by a connecting rod 14. A rubber 15 formed in a rectangular plate shape as a buffer material is attached to the surface of the support plate 13. Further, a pair of substantially triangular support plates 16 extending downward are provided at both left and right ends of the upper plate 10, and wheels 17 are rotatably supported on the support plate 16. A storage member 18 (see FIG. 1) for storing an auxiliary wheel unit 70 (described later) vertically is provided at the center of the front plate 11 and on the back side above the window 12. The housing member 18 has a magnet portion (not shown), and adsorbs an iron unit main body 71 provided in the auxiliary wheel unit 70.

  The upper horizontal plate 7 is suspended by a spring 20 and is slidable up and down along the vertical pipe 6 (see arrow C in FIG. 3 described later). The upper horizontal plate 7 is engaged with an arm 50 (main body side arm 51) described later and has a function of restricting the rotational movement of the arm 50. 2 shown in FIG. 2 is a protective material formed of rubber or the like, and this protective material 21 is a member that protects the upper horizontal plate 7 when the arm 50 (main body side arm 51) is engaged. The horizontal plate 7 is affixed to the substantially central peripheral surface. Moreover, 22 shown in FIG. 2 is a handle, and this handle 22 is provided in the center of the lower side of the rear surface of the upper horizontal plate 7 so as to protrude in a U-shape. The handle 22 is used when sliding the upper horizontal plate 7 up and down, and can also be used with one hand when moving the hand cart 1 rearward.

  As shown in FIG. 2, the middle horizontal plate 8 is provided with a cushioning material 23 formed of rubber or the like for protecting the middle horizontal plate 8 when it comes into contact with the arm 50 at the front center. A pair of substantially trapezoidal support plates 24 for attaching an auxiliary wheel unit 70, which will be described later, project from the rear side approximately at the rear side. The auxiliary wheel unit 70 is pivotally supported by the support plate 24 on the rear side so as to be able to rotate a predetermined section.

  As shown by an arrow A in FIG. 3, the arm 50 is attached to the cart main body 2 so as to be rotatable in a predetermined section vertically on the front side. FIG. 3 is an explanatory diagram (right side view) showing how the arm 50 rotates. The arm 50 is roughly divided into a main body side arm 51 and a front end side arm 52. As shown by an arrow B, the front end side arm 52 is disposed movably back and forth on the front end side of the main body side arm 51. ing. The main body side arm 51 and the front end side arm 52 are formed in a substantially quadrangular prism shape having a hollow inside, and the front end side arm 52 is inserted into the main body side arm 51 so as to be movable. The arm 50 (main body side arm 51) is located at the position indicated by the two-dot chain line in the center of the front side of the cart main body 2 shown in FIGS. 2 and approximately 120 degrees with respect to 2).

  A support arm 53 rotatably supported by the horizontal pipe 5 is connected to the rear end portion of the main body side arm 51, and the main body side arm 51 and the support arm 53 are formed in a substantially L shape. That is, the arm 50 is rotated by the support arm 53 rotating about the horizontal pipe 5 as an axis. Further, as shown in FIG. 2, an engagement plate 54 protrudes from the support arm 53, and the engagement plate 54 is configured such that the arm 50 rotates about 90 degrees with respect to the cart body 2 and the upper horizontal plate 7. It engages with (protective material 21).

  That is, when the arm 50 is rotated from the origin position, the upper horizontal plate 7 is moved downward against the urging force of the spring 20 from the origin position so as not to collide with the support arm 53 so that the arm 50 is substantially horizontal or higher. After the rotation, the upper horizontal plate 7 is returned to the original position by the urging of the spring 20, and the engagement plate 54 is engaged with the upper horizontal plate 7 (protective member 21). Thereby, the arm 50 is maintained in a state of being substantially perpendicular to the cart body 2. That is, the engagement plate 54 functions as a rotation restricting portion that restricts the rotation of the arm 50 from the horizontal state to the downward direction.

  The main body side arm 51 is attached with a sandwiching portion 55 for sandwiching a transported object by an L-shaped bar 56. The L-shaped bar 56 is attached to both side surfaces of the main body side arm 51 so as to be rotatable up and down by a support shaft 57. Therefore, the sandwiching portion 55 can also be rotated up and down in conjunction with the L-shaped bar 56. On the other hand, a holding part 58 for holding and holding a transported object is attached to the distal arm 52 by an L-shaped bar 59. That is, the sandwiching portion 55 and the sandwiching portion 58 form a pair, and the sandwiched portion 55 and the sandwiching portion 58 sandwich and sandwich the transported material. A rubber 55a and a rubber 58a are attached to the surfaces of the sandwiching portion 55 and the sandwiching portion 58 to protect the transported material and increase the sandwiching force (friction force). The L-shaped rod 59 passes through the inside of the distal end side arm 52 and is attached so as to be rotatable up and down by a support shaft 60 inserted through the hole 61. Therefore, the clamping part 58 can also be rotated up and down in conjunction with the L-shaped bar 59.

  In the figure, 62 is a hole for changing the mounting position of the support shaft 60. There are roughly two types of gaming machines, pachinko gaming machines and pachislot gaming machines (rotating-type gaming machines). These gaming machines have a uniform height (810 cm), but the width is Pachinko machines are longer than pachislot machines (pachinko machines are 520 cm and pachislot machines are 480 cm). That is, the attachment position of the clamping part 58 can be changed, and thereby the distance between the clamping part 55 and the clamping part 58 can be changed according to the transported goods (type of gaming machine). When the transported object is a pachislot machine, the support shaft 60 is attached to the hole 61, and when the transported object is a pachinko game machine, the support shaft 60 is attached to the hole 62. In the figure, reference numeral 63 denotes a fixing pin for fixing the support shaft 60 to the hole 62. Reference numeral 64 in the drawing is a knob for rotating the arm 50. Note that the holes 61 and 62 may be replaced with one long hole. Moreover, you may make it provide three or more holes according to the number of classifications of a conveyed product.

The distance between the sandwiching portion 55 and the sandwiching portion 58 is set longer than the width of the transported object by a predetermined length (for example, about 40 cm) so that the transported object can be easily sandwiched. (Hereinafter, this set length is also referred to as “excess length”). Therefore, when the transported object is sandwiched between the sandwiching section 55 and the sandwiching section 58, the leading end side arm 52 to which the sandwiching section 58 is attached can be moved backward by an excessive length.
An urging means 68 shown in FIG. 3 is provided inside the main body side arm 51, and this urging means 68 urges the distal end side arm 52 in the forward direction as indicated by an arrow D. . Therefore, the distal arm 52 is always in the most extended state (hereinafter also referred to as the longest state) as shown in FIG. A rod member 66 is connected to the rear side of the distal arm 52, and the backward movement of the distal arm 52 operates a link mechanism portion 35 described later to urge the rod member 66. This can be done by moving backward against the bias of the means 68.

  Here, reference numeral 65 in the figure denotes a reference portion. That is, when the transported object is held between the holding portion 55 and the holding portion 58, the distal arm 52 is moved backward until the reference portion 65 disappears. (See FIG. 7 described later). That is, the length of the reference portion 65 is equivalent to the surplus length. The surplus length is set so that the distance between the sandwiching portion 55 and the sandwiching portion 58 is slightly shorter than the transported object (about 2 to 3 mm) when the distal arm 52 is moved backward by the surplus length. May be. Even if the surplus length is set in this way, the rubber 55a, 58a bends so that the transported object can be clamped between the clamping unit 55 and the clamping unit 58 more strongly.

  A stopper control unit 25 and a link mechanism unit 35 are provided at the rear part of the main body side arm 51. The stopper control unit 25 has a function of controlling the movement of the front end side arm 52 in the front-rear direction by controlling the operation of a stopper mechanism unit 45 built in the main body side arm 51 described later. The link mechanism unit 35 has a function of pulling the tip side arm 52 (moving it backward) by converting the rotational motion of the operation unit 36 to be described later into a linear motion when holding a transported object.

FIG. 4 is an explanatory diagram illustrating the configuration of the stopper control unit 25, and FIG. 5 is an explanatory diagram illustrating operating states of the stopper control unit 25 and the stopper mechanism unit 45.
The stopper control unit 25 includes a substantially box-shaped housing 26 attached to the upper surface of the main body side arm 51, and a reciprocating plunger 27 inserted through the housing 26. The housing 26 has a U-shaped groove 28 surrounded by an upper surface 26a, a front surface 26b, a rear surface 26c, and two side surfaces 26d, and a leaf spring 29 is provided in the groove 28. The leaf spring 29 includes a fixing plate 29a fixed to the front surface 26b, which is the tip side of the arm 50 (hereinafter also simply referred to as the tip side or the front side), and the main body side of the arm 50 (hereinafter simply referred to as the main body). And an L-shaped plate 29b as a free end extending to the rear surface 26c side. The L-shaped plate 29b is formed in an L shape by a horizontal plate portion 29e substantially parallel to the upper surface 26a, and a vertical plate portion 29f substantially parallel to the fixed plate 29a (and the front surface 26b), and is always on the upper surface 26a side (hereinafter referred to as “the upper plate 26a”). (Also simply referred to as the upper side). Holes 29c and 29d and holes 26e and 26f for inserting the plunger 27 are formed in the fixing plate 29a and the vertical plate portion 29f, and the front surface 26b and the rear surface 26c, respectively. A first button 30 is attached to the tip of the plunger 27 on the main body side, and a second button 31 is attached to the upper surface 26a side of the L-shaped plate 29b.

In the plunger 27, a circular groove 32 is formed at a substantially central location, and a flange 19 is fixed along the outer periphery at a location near the main body near the groove 32. The flange 19 is a member that contacts the rear surface 26c of the housing 26 and restricts the movement of the plunger 27 toward the main body. A spring 33 is inserted into the plunger 27. The plunger 27 is formed with a larger diameter on the main body side than on the distal end side, and has a stepped portion 34 at the boundary thereof. The spring 33 is inserted into the distal end side, which is the small diameter side of the plunger 27, and is provided so as to be interposed between the stepped portion 34 and the fixing plate 29a.
In addition, a hole 26e through which the second button 31 can be projected and retracted is formed in the approximate center of the upper surface 26a of the housing 26.

It is the side view and bottom view of the control part 25. In the first position, the plunger 27 has the first button 30 located closest to the main body, and the second button 31 is located at substantially the same height as the upper surface 26a of the housing 26 (the second button 31 is Slightly peeking from the side). In the second position, the plunger 27 is located on the most distal end side, and the second button 31 protrudes from the upper surface 26 a of the housing 26.

In the first position shown in FIG. 4A, the L-shaped plate 29 b of the leaf spring 29 has the vertical plate portion 29 f engaged with the large-diameter plunger 27 in the vicinity of the step portion 34. Further, the flange 19 is in contact with the rear surface 26c of the housing 26 and restricts the movement of the plunger 27 toward the main body. From this state, the first button 30 is pressed forward against the bias of the spring 33 as indicated by an arrow P1. Then, as shown in FIG. 4B, the vertical plate portion 29f is fitted into the groove 32 by the upward bias of the L-shaped plate 29b itself, and the plunger 27 moves from the first position to the second position. Then stop. At this time, the L-shaped plate 29 b moves (rotates) upward, and the second button 31 protrudes from the upper surface 26 a of the housing 26. Further, when the second button 31 is pressed downward against the bias of the leaf spring 29 as shown by an arrow P2 in the state of the second position shown in FIG. The fitting with the groove 32 is released, the plunger 27 is moved to the rear side by the biasing of the spring 33 toward the main body side, and the rod 19 comes into contact with the rear surface 26c of the housing 26 to stop at the first position.
That is, the stopper control unit 25 can move the plunger 27 from the first position to the second position with a one-touch operation that only presses the first button 30, and only presses the second button 31. The one-touch operation can move from the second position to the first position.

  The configuration of the stopper mechanism unit 45 will be described with reference to FIG. The stopper mechanism 45 is provided inside the rear end of the main body side arm 51 and substantially above the connection portion with the support arm 53. The stopper mechanism portion 45 includes a stopper plate 46, a position restricting portion 47, and a spring 48. The stopper plate 46 is formed by connecting a circular rod portion 46 a to an upper portion of a rectangular plate portion 46 b, and the rod portion 46 a has a tip portion slightly protruding from the upper surface of the main body side arm 51. The plate portion 46 b is provided such that its lower end portion engages with the position restricting portion 47. The plate portion 46b has a circular hole 46c formed at the center thereof, and a rod member 66 connected to the distal arm 52 is inserted through the hole 46c. The bar member 66 passes through the main body side arm 51 in a horizontal manner, and its rear end protrudes from the main body side arm 51 and is connected to a link mechanism portion 35 described later.

  A spring 48 is inserted into the bar member 66 between the plate portion 46 b of the stopper plate 46 and the rear end cover 67 of the main body side arm 51. The spring 48 always functions as a biasing means that biases the vicinity of the center of the plate portion 46b in the forward direction. The position restricting portion 47 includes a circular front bar 47 a and a rear bar 47 b that are horizontally stretched on the lower side of both side surfaces of the main body side arm 51. The front bar 47a and the rear bar 47b are provided in parallel and with a gap at the same height, and the lower portion of the plate portion 46b is loosely fitted in this gap. That is, the position restricting portion 47 functions as a restricting member that restricts the forward movement of the lower portion of the stopper plate 46.

  FIG. 5A is an explanatory view showing a case where the stopper plate 46 is in the first state, and FIG. 5B is an explanatory view showing a case where the stopper plate 46 is in the second state. In the first state, the plunger 27 is in the first position, and the first button 30 engages with the rod portion 46a of the stopper plate 46 against the bias of the spring 48 to press the rod portion 46a toward the main body. To do. Thereby, the attitude | position of the stopper board 46 is hold | maintained substantially perpendicularly, and the hole 46c provided in the board part 46b and the bar member 66 are spaced apart, without contacting. As a result, the bar member 66, that is, the distal arm 52 can be moved in the front-rear direction as indicated by the arrow FB. In this first state, the distal arm 52 is in the longest state (see FIG. 3) due to the biasing force of the biasing means 68. In the figure, reference numerals 38 and 39 denote sliders and springs constituting the link mechanism portion 35, which will be described later.

  When the first button 30 is pressed toward the distal end side in the state where the stopper plate 46 shown in FIG. 5A is in the first state, the plunger 27 is moved from the first position as shown in FIG. 5B. The first button 30 and the bar portion 46a of the stopper plate 46 are moved away from each other, and the first button 30 is disengaged from the bar portion 46a. Then, since the lower portion of the plate portion 46b comes into contact with the front rod 47a of the position restricting portion 47 due to the bias of the spring 48, the movement of the stopper plate 46 in the forward direction is restricted. 46a and the plate portion 46b) are inclined forward, and the plate portion 46b and the rod member 66 abut at a point A and a point B shown in FIG. That is, the hole 46c of the stopper plate 46 contacts the upper surface (point A) and the lower surface (point B) of the rod member 66, and the stopper plate 46 is inclined forward from the substantially vertical posture (first state) ( The second state is maintained. As a result, as shown by the arrow B, the bar member 66, that is, the distal end side arm 52 is allowed to move in the backward direction and is restricted from moving in the forward direction. The backward movement is possible because the backward movement acts in a direction in which the stopper plate 46 returns to the substantially vertical posture (first state), and the forward movement is restricted. This is because the forward movement acts in a direction in which the stopper plate 46 tends to tilt further forward.

In the second state shown in FIG. 5B, when the second button 31 is pressed downward (see arrow P2 in FIG. 4B), the plunger 27 moves from the second position to the first position. Since the stopper plate 46 changes from the second state to the first state, the distal end side arm 52 immediately returns to the longest state shown in FIG. Thereby, the transported goods (game machine) clamped can be easily removed from the hand cart 1.
That is, the stopper mechanism 45 can change the stopper plate 46 from the first state to the second state with a one-touch operation that only presses the first button 30 and only presses the second button 31. The one state can be changed from the second state to the first state. Thereby, a conveyed product (game machine) can be attached to or removed from the hand cart 1 very easily.

  FIG. 6 is an explanatory diagram showing the configuration of the link mechanism unit 35. The link mechanism unit 35 includes a first link member 40, a second link 41, a third link 42, and a slider 38. FIG. 6B is a perspective view of the first link member 40 viewed from the front side, and FIG. 6C is a perspective view of the first link member 40 viewed from the back side. As shown in FIGS. 6B and 6C, the first link member 40 has a pair of parallel first links 40a, and a connecting plate is provided between the front end portions of the first links 40a and 40a. 40b is stretched over. Further, a substantially triangular projection 40c is provided on the back side of the connecting plate 40b. As will be described in detail later, the protrusion 40c is engaged with the rod member 66.

  FIG. 6A is a partially enlarged plan view of FIG. 3 and shows a state in which the link mechanism portion 35 is attached to the main body side arm 51. The first link member 40 is provided such that one end side of the first link 40a is pivotally supported on both side surfaces of the main body side arm 51 by the first pivotal support portion 43 and is rotatable up and down. One end side of the second link 41 provided in a pair of parallel shapes and the other end side of the first link 40a are provided so as to be rotatable up and down by the first joint 44. One end side of the third link 42 provided in a pair of parallel shapes and the other end side of the second link 41 are provided so as to be rotatable up and down by a second joint 49. The positional relationship between these links is such that the first link 40 a is provided outside the second link 41, and the second link 41 is provided outside the third link 42.

  Further, the slider 38 is loosely inserted in the rod member 66 so as to be slidable in the front-rear direction, and a nut 80 is attached to the rear end thereof. Further, a spring 39 is inserted into the rod member 66 so as to be interposed between the slider 38 and the nut 80. Here, as shown in FIG. 6A, the second link 41 and the third link 42 are attached so as to sandwich the slider 38 with the second joint 49. Therefore, the second link 41 and the third link 42 can move in the front-rear direction along the bar member 66 together with the slider 38 in addition to the vertical rotation. Further, as shown in FIGS. 6D and 6E, the other end side of the third link 42 is a free end, and a grip 37 is provided there. The grip 37 and the third link 42 make up the operation unit 36. That is, the operation unit 36 rotates up and down and is movable in the front-rear and horizontal directions.

  FIGS. 6D and 6E show a state when the operation unit 36 is operated to move the bar member 66 (front end side arm 52) in the backward direction by the link mechanism unit 35 so as to clamp the conveyed product. ing. When sandwiching a transported item, the grip 37 is operated to rotate the operation unit 36 (third link 42) upward, and the link mechanism unit 35 is moved from the state shown in FIG. 3 to FIG. 6D. 6 (e) in order (see arrow D in FIG. 7 described later). The link mechanism unit 35 is moved only by the operation unit 36 until the transition from the position (origin position) shown in FIG. 3 to the position shown in FIG. 6D, and other members are not displaced. And when the operation part 36 rotates to the position shown in FIG.6 (d), the predetermined site | part of the one side 42a shown in FIG.6 (d) of the 3rd link 42 will be shown to Fig.6 (a) of the 1st joint 44. FIG. It contacts the circular engagement portion 44a.

  When the operation portion 36 is further rotated upward from the state of FIG. 6D, the one side surface 42a of the third link 42 slides on the outer periphery while pushing up the circular engagement portion 44a of the first joint 44. Rotate to. As a result, the first link 40a rotates upward about the first shaft support portion 43, the second link 41 moves rearward together with the slider 38 while rotating backward about the first joint 44, and the third link The link 42 moves rearward together with the slider 38 while rotating upward about the second joint 49. When the slider 38 moves rearward, the spring 39 moves the bar member 66 backward while contracting between the slider 38 and the nut 80. That is, the front end side arm 52 moves rearward and is drawn into the main body side arm 51.

  When the operation unit 36 is further rotated to the position shown in FIG. 6 (e), the first link 40a and the second link 41 become substantially straight as shown in FIG. 6 (e) immediately after becoming straight. Bends in a reverse shape. The rod member 66 (front end side arm 52) is moved to the most rearward direction when the first link 40a and the second link 41 are linear, and this state is held by the stopper mechanism 45. That is, since the forward movement of the bar member 66 is restricted, the sandwiching of the transported object by the sandwiching portion 55 and the sandwiching portion 58 is thus completed in this state. The first link 40a and the second link 41 are bent from a straight shape to a substantially reverse shape because the rotation of the operation unit 36 is a position where the first link 40a and the second link 41 are linear. At this time, the reaction of the first link 40a and the second link 41 is also added, and the protrusion 40c provided on the first link member 40 collides with the upper surface of the rod member 66 with a high force. As a result, further downward rotation of the first link 40a is restricted, and the operation unit 36 can no longer rotate. Thus, the operator finishes the operation of sandwiching the transported goods by the operation unit 36. Recognize that

  That is, in the case of performing the sandwiching operation of the transported object, it can be achieved by an extremely simple operation of simply operating the operation unit 36 until it cannot be rotated. Since the collision sound is generated when the projection 40c collides with the upper surface of the bar member 66, the operator recognizes that the operation for pinching the transported object has been completed by this collision sound (hereinafter also referred to as an end sound). can do. That is, the protrusion 40c functions as a positioning member of the link mechanism portion at the end of the transporting object sandwiching operation, and also has a function as a notification unit that notifies that the transporting object sandwiching operation has been completed.

  FIG. 7 is an explanatory view showing a state where the pachislot machine S as a transported object is sandwiched between the hand cart 1. The procedure for pinching the pachislot machine S to the hand cart 1 is performed as follows. First, the upper horizontal plate 7 is moved downward from the origin position, and the arm 50 is rotated by the knob 64 to a position higher than the pachislot machine S as shown by a two-dot chain line in FIG. Next, the arm 50 is rotated downward until the engagement plate 54 comes into contact with the upper horizontal plate 7 (protective member 21) returned to the origin position. In this state, the arm 50 is in a substantially horizontal state as shown in the solid line of FIG. 3 and FIG. 7, and the arm 50 is placed on the upper surface S4 of the pachislot machine S placed on the floor surface F. It becomes a state. That is, the arm 50 is set so that the height from the floor surface F is substantially equal to the height of the pachislot gaming machine S when in the horizontal state.

  Next, the first button 30 of the stopper controller 25 is pushed forward to bring the stopper mechanism 45 into the state shown in FIG. 5B where the stopper plate 46 is in the second state. That is, the front end side arm 52 that can move in the front-rear direction is restricted so that it can move only in the rear direction. Then, as shown by an arrow D in FIG. 7, the grip 37 is operated to rotate the operation unit 36 until it cannot be rotated upward. Then, as shown by an arrow B, the front end side arm 52 is drawn into the main body side arm 51 (moves backward) until the reference portion 65 shown in FIG. 3 is not visible, and thereby both sides of the pachislot machine S The surfaces S1 and S2 are sandwiched between the sandwiching portion 55 and the sandwiching portion 58, and the pachislot gaming machine S is securely sandwiched. Note that whether or not the pinching operation of the pachislot machine S has been completed can be confirmed by the fact that the reference portion 65 is not visible and the end sound is emitted. Further, in the state where the pachislot gaming machine S is sandwiched, the lower surface of the side surface S2 on the main body side of the pachislot gaming machine S abuts on the rubber 15 of the support plate 13, thereby the rubber 55 a of the clamping unit 55 and the clamping unit 58. , 58a and the rubber 15 of the support plate 13 protect the conveyed product and increase the frictional force with the conveyed item.

  In order to remove the pachislot gaming machine S from the hand cart 1, the second button 31 of the stopper control unit 25 may be pushed down with the pachislot gaming machine S shown in FIG. In this way, the stopper plate 46 is in the first state, the restriction of the forward movement of the distal arm 52 is released, and the distal arm 52 is moved forward by the urging means 68 shown in FIG. To the most extended state (longest state). As a result, the pinching portion 58 moves in the forward direction and is separated from the pachislot gaming machine S, so that the pachislot gaming machine S can be detached from the hand cart 1. That is, the pachislot machine S can be removed from the hand cart 1 with a one-touch operation very easily.

Here, when the arm 50 is placed on the upper surface S4 of the pachislot machine S (positioned above), the arm 50 is inclined and parallel to the pachislot machine S as shown in FIG. It may not be possible. If the pachislot gaming machine S is sandwiched while the arm 50 is inclined, a gap or the like is formed between the pachislot gaming machine S and the sandwiching unit 55 and the sandwiching unit 58, and cannot be properly sandwiched. As a result, the clamping force is weakened, which is not preferable. Therefore, in order to solve such a problem, the following measures are taken in the hand cart 1 of the present invention.
FIG. 8 is an explanatory diagram showing the configuration of the clamping unit 58 attached to the distal arm 52 and the state when the pachislot gaming machine S is clamped when the arm 50 is inclined. First, the structure of the clamping part 58 is demonstrated with reference to Fig.8 (a). FIG. 8A is an explanatory diagram showing the configuration of the clamping unit 58 and the state of attachment of the clamping unit 58 to the L-shaped bar 59. In the following description, please refer to FIGS.

  As described above, the sandwiching portion 58 is attached to the distal arm 52 by the L-shaped bar 59. On the opposite side of the clamping surface (rubber 58a) of the clamping part 58, a substantially trapezoidal support plate 58b extending in the forward direction from both left and right ends is erected, and a support shaft 58c is provided at the approximate center of the support plates 58b and 58b. Are fixed to the support plates 58b and 58b so as to be bridged. On the other hand, a cylindrical portion 59a is provided at the tip of the L-shaped rod 59, and a support shaft 58c is loosely inserted into the cylindrical portion 59a. With this configuration, the sandwiching portion 58 can be rotated up and down around the support shaft 58c, and can be moved to the left and right with respect to the L-shaped bar 59 as indicated by an arrow LR in FIG. Yes. In the figure, 58d is a spring, which will be described later.

  FIG. 8B is an explanatory diagram showing a state where the pachislot gaming machine S is sandwiched in a state where the arm 50 is inclined. When the arm 50 is inclined (tilted to the right in the drawing) and the operating portion 36 is operated as described above to move the distal arm 52 in the backward direction, the pinching portion 58 is also in a pachislot game. It abuts on the side surface S1 on the front end side of the machine S in a state inclined to the right side. Then, as shown in FIG. 8B, the right side of the sandwiching portion 58 is in a state of floating from the side surface S1, and when the distal arm 52 is further moved rearward in this state, the sandwiching portion 58 is The hand cart 1 moves to the left as shown by the arrow L, and at the same time, the hand cart 1 rotates to the left as shown by the arrow C (counterclockwise in FIG. 8). As a result, as shown in FIG. 8C, the arm 50 is in parallel with the pachislot gaming machine S, that is, the clamping surface (rubber 58a) of the clamping part 58 is in contact with the side surface S1 without a gap. In the state, the pachislot machine S is held. In this way, by providing the holding portion 58 so as to be movable in a predetermined direction in the left-right direction, a function of preventing the lateral displacement of the transported material is provided, and even when the pachislot gaming machine S is to be held in a state where the arm 50 is inclined. Even in such a case, the arm 50 can be automatically held in parallel with the pachislot machine S and properly held as shown in FIG.

  In order to transport the pachislot gaming machine S after pinching the pachislot gaming machine S, the hand cart 1 (cart body 2) is operated by rotating the handle 4 downward as shown by an arrow D in FIG. Tilt to the rear side. Then, the pachislot machine S is lifted from the floor surface F while being sandwiched between the hand carts 1. That is, the state shown in FIG. 7 is changed to the state shown in FIG. In this state, the hand cart 1 can be moved in a desired direction by operating the handle 4 to push, pull or rotate the hand cart 1. That is, the pachislot machine S having a large weight and volume can be transported very easily even by a weak person such as a woman or an elderly person. FIG. 9 is an explanatory diagram showing a state in which the pachislot machine S sandwiched between the hand carts 1 is lifted from the floor surface F. 9 shows a state in which the link mechanism unit 35 and the operation unit 36 have returned to the state before the pachislot gaming machine S is held (the state shown in FIG. 3) by the bias of the spring 39.

Next, the detail of the attachment state of the clamping part 55 and the clamping part 58 is demonstrated. As described above, the sandwiching portion 55 is attached to the main body side arm 51 by the L-shaped rod 56, and the sandwiching portion 58 is attached to the distal end side arm 52 by the L-shaped rod 59. FIG. 10 is an explanatory view showing the attachment state of the sandwiching portion 55 and the sandwiching portion 58, FIG. 10 (a) shows the attachment state of the sandwiching portion 58 viewed from the front end side, and FIG. 10 (b) shows the main body. The attachment state of the clamping part 55 seen from the side is shown.
With reference to FIG. 10 (a), the structure of the clamping part 58 is as having shown in FIG. 8 mentioned above, and the spring 58d is stretched between the support plates 58b and 58b. The spring 58d is disposed on the distal end side of the L-shaped rod 59 and slightly above the support shaft 58c and the cylindrical portion 59a. The spring 58d is supported by the L-shaped bar 59 when the pachislot machine S is not being clamped, and reduces the rotation of the clamp 58 with its own weight and the rubber 58a facing downward. As a result, as shown in FIG. 3, the sandwiching portion 58 is maintained in a state slightly inclined inward.

Two rod members 81 are provided vertically inside the distal arm 52, and two springs 82 and one plate-like swing member 83 are loosely fitted to each of the rod members 81. ing. The swing member 83 is provided in contact with the upper end of the spring 82 and resting on the spring 82.
As described above, the L-shaped bar 59 passes through the inside of the distal arm 52 and is attached to the support shaft 60 so as to be rotatable up and down. Therefore, the holding portion 58 can also be rotated up and down in conjunction with the L-shaped bar 59. (See FIGS. 3 and 7). Here, as shown in FIG. 10A, the L-shaped bar 59 extends upward from the tubular portion 59 a, bends after passing through the distal end side of the swinging member 83, and moves upward on the swinging member 83. It is supposed to pass. Accordingly, as shown by an arrow A in FIG. 11 described later, when the L-shaped bar 59 rotates downward, the swing member 83 moves downward along the bar member 81 and the spring 82 contracts. .

Referring to FIG. 10B, the sandwiching portion 55 is provided with a substantially trapezoidal support plate 55b extending in the rearward direction from the left and right on the opposite side of the sandwiching surface (rubber 55a) of the sandwiching portion 55. A support shaft 55c is fixed to the support plates 55b and 55b so as to be bridged over substantially lower portions of the support plates 55b and 55b. The L-shaped rod 56 has a cylindrical portion 56a at the tip and two L-shaped portions 56b extending upward from the cylindrical portion 56a, and a support shaft 55c is loosely inserted into the cylindrical portion 56a. With this configuration, the sandwiching portion 55 can be rotated up and down around the support shaft 55c.
Further, a latching portion 55d for latching one end of the spring 84 is provided at a position slightly above the cylindrical portion 56a and on the opposite side of the clamping surface of the clamping portion 55, and the other end of the spring 84 is It is latched by the latching | locking part 53a of the support arm 53 (refer FIG. 3). When the pachislot gaming machine S is not clamped, the spring 84 reduces the rotation of the clamping portion 55 in its own weight with the rubber 55a facing downward. As a result, as shown in FIG. 3, the clamping part 55 is maintained in a state slightly inclined inward.

  That is, the sandwiching unit 55 and the sandwiching unit 5 are both maintained in a slightly inclined state when the pachislot machine S is not sandwiched, and therefore the distance between the sandwiching unit 55 and the sandwiching unit 58 is The distance between the lower end sides is the longest. Accordingly, when the pachislot gaming machine S is sandwiched, the arm 50 can be easily set above the pachislot gaming machine S so that the pachislot gaming machine S is positioned between the sandwiching part 55 and the sandwiching part 58. That is, when the pachislot gaming machine S is sandwiched, the clamping surfaces (rubbers 55a and 58a) of the clamping unit 55 and the clamping unit 58 are provided so as to be laterally viewed until contacting the pachislot gaming machine S. After coming into contact with the pachislot machine S, a transition is made so as to be parallel in a side view as the distal arm 52 moves rearward. According to this configuration, the arm 50 can be set so that the pachislot gaming machine S is positioned between the clamping unit 55 and the clamping unit 58 very easily, and the pachislot gaming machine can be firmly secured between the clamping unit 55 and the clamping unit 58. S can be held.

  As described above, the L-shaped bar 56 is attached to both side surfaces of the main body side arm 51 so as to be rotatable up and down by the support shaft 57 (see FIGS. 3 and 7). That is, L-shaped portions 56 b extend on both side surfaces of the main body side arm 51, and the L-shaped portions 56 b are attached to the support shaft 57 so as to be vertically rotatable. Accordingly, the sandwiching portion 55 can also be rotated up and down in conjunction with the L-shaped bar 56. As a result, as shown by an arrow B in FIG. 11 described later, when the L-shaped rod 56 rotates downward, the spring 84 extends downward.

FIG. 11 is an explanatory diagram showing the operation state of the clamping unit 55 and the L-shaped bar 56 and the clamping unit 58 and the L-shaped bar 59 when the pachislot gaming machine S is clamped. When the pachislot gaming machine S is sandwiched and the pachislot gaming machine S is lifted from the floor surface F as shown in FIG. 9 described above, the L-shaped bar 59 is slightly lifted by the weight of the pachislot gaming machine S. The L-shaped rod 56 rotates downward about the support shaft 60 as shown by the arrow A against the urging of the spring 82, and the L-shaped rod 56 supports the support shaft as shown by the arrow B against the urging of the spring 84. Rotate downward at 57. Then, as indicated by a two-dot chain line in FIG. 11, the distance between the rubber 55a of the clamping unit 55 and the rubber 58a of the clamping unit 58 becomes short.
That is, the sandwiching portion 55 and the sandwiching portion 58 are pivotally supported by the main body side arm 51 and the distal end side arm 52 so as to be able to rotate downward so that the distance between them is shortened while the pachislot gaming machine S is sandwiched. Thereby, the rubber 55a, 58a is bent and the pachislot machine S in a state of being floated during transportation can be more strongly held between the holding portion 55 and the holding portion 58. In this case, the clamping force of the clamping parts 55 and 58 becomes stronger as the L-shaped bars 56 and 59 rotate downward. Note that the pachislot machine S is sandwiched between the rubbers 55a and 58a and is in contact with the rubber 15 of the support plate 13 so that the pachislot game is caused by friction with the rubbers 55a, 58a and 15. Only the machine S is hardly displaced downward. Further, when the pachislot gaming machine S is detached from the hand cart 1, the L-shaped bars 56 and 59 are automatically returned to the positions before the pachislot gaming machine S is clamped by the urging of the springs 82 and 84.

Next, the auxiliary wheel unit 70 will be described with reference to FIG. FIG. 12 is an explanatory diagram showing a usage state of the auxiliary wheel unit 70. The auxiliary wheel unit 70 is a member used when it is desired to stably transport the pachislot gaming machine S with three wheels. When not in use, as described above, the storage member 18 (see FIG. 1) is stored in parallel with the vertical pipe 6 of the cart body 2 and protruded from the middle horizontal plate 8 as shown in FIG. The support plate 24 is pivotally supported so as to be able to rotate a predetermined section from the origin position up and down on the rear side. That is, the auxiliary wheel unit 70 extends from an unused state folded at the origin position (also referred to as a storage position) at the rear center of the cart body 2 shown in FIGS. 1 and 2 to a use position indicated by an arrow E in FIG. The rear side is rotatable upward.
That is, in the hand cart 1, when not in use, the arm 50 and the auxiliary wheel unit 70 can be folded vertically and stored along the cart body 2 as shown in FIG. Thereby, the width | variety of the hand cart 1 becomes small and does not take space when the hand cart 1 is stored. As a result, the space for storing the hand cart 1 can be reduced.

In FIG. 12, reference numeral 71 denotes a unit main body as a cylindrical column, and an auxiliary wheel 73 is rotatably attached to the lower portion of the unit main body 71 via an L-shaped support plate 72. On the other hand, a fixing bolt 74 is attached to the upper portion of the unit main body 71. The fixing bolt 74 has a function of fixing the auxiliary wheel unit 70 in use.
The auxiliary wheel unit 70 rotates to the upper side of the rear side as much as possible to rotate to the use position indicated by the arrow E in FIG. That is, when the auxiliary wheel unit 70 is rotated to the use position, the engaging portion 75 formed at the upper end of the unit main body 71 engages with the middle horizontal plate 8 of the cart main body 2 and further upwards to the rear side. Rotation is regulated. Thereby, the position of the auxiliary wheel unit 70 is fixed. Then, with the position of the auxiliary wheel unit 70 fixed, the fixing bolt 74 is rotated clockwise as indicated by an arrow T in FIG. Then, the fixing bolt 74 protrudes from the tip of the unit main body 71 and is screwed into a screw hole provided in the middle horizontal plate 8, whereby the auxiliary wheel unit 70 is restricted from moving from the use position. In addition, the holding part 74a is provided in the head of the fixing bolt 74, and the fixing bolt 74 can be easily screwed to the middle horizontal plate 8 by rotating the holding part 74a.

Here, after pinching the pachislot machine S, the hand cart 1 (cart main body 2) is tilted rearward, and the auxiliary wheel unit 70 (unit main body 71) is rotated to the maximum at the rear side to assist auxiliary wheels. In a state in which 73 is in contact with the floor F, the diagonal line (shown by the alternate long and short dash line) passing through the uppermost point P1 and the lowermost point P2 of the pachislot machine S becomes almost vertical as shown in FIG. ing. In other words, the maximum rotation angle at which the auxiliary wheel unit 70 is used is preset to an angle at which the diagonal line passing through the uppermost point P1 and the lowermost point P2 of the pachislot machine S is substantially vertical. When the diagonal line passing through the uppermost point P1 and the lowermost point P2 of the pachislot machine S becomes almost vertical, the diagonal line overlaps the center of gravity line of the pachislot machine S indicated by the arrow G. Thereby, the pachislot machine S is in a state where the balance in the front-rear direction is most stable, and as a result, the pachislot machine S is transported by the hand cart 1 in an extremely safe state in which troubles such as a fall are suppressed. Can do.
In addition, although the transport by the hand cart 1 is normally performed by operating the handle 4, when the handle 4 is used even when the handle 22 is used when the auxiliary wheel 73 is used for three wheels, the handle 4 is used. And can be done without inferiority. In particular, when the handle 22 is used, since it can be operated with one hand, two hand carts 1 can be used together.

In addition, in FIG. 12 described above, the case where the transported item is a pachislot machine S is illustrated, but when the transported item is a pachinko gaming machine, the pachinko gaming machine is wider than the pachislot machine S. Similarly, in order to make the diagonal line of the pachinko gaming machine set in the hand cart 1 substantially vertical, the maximum rotation angle at which the auxiliary wheel unit 70 is used may be increased accordingly.
If the pachislot machine S is set in the hand cart 1 in which the use position of the auxiliary wheel unit 70 is matched to the pachinko gaming machine, the center of gravity line comes to the rear side of the diagonal line. The load is greater on the rear side than on the front side. However, since the rear side of the hand cart 1 is supported by the wheels 17 and the auxiliary wheels 73, the hand cart 1 can be transported with almost no trouble. On the other hand, when the pachinko gaming machine is set in the hand cart 1 in which the use position of the auxiliary wheel unit 70 is matched to the pachislot machine S, the center of gravity line is more forward than the diagonal line. 1, the load is greater on the front side than on the rear side. In this case, since there is nothing on the front side of the hand cart 1, the hand cart 1 is likely to fall over to the front side.
That is, the hand cart 1 (cart body 2) is tilted rearward after the transported object is sandwiched, and the auxiliary wheel unit 70 (unit main body 71) is rotated to the maximum at the rear side to bring the auxiliary wheel 73 into the floor. In a state where it is in contact with the surface F, the diagonal line passing through the uppermost point and the lowermost point of the transported object should be almost vertical (overlapping the barycentric line), or the barycentric line should be on the rear side of the diagonal line It is desirable to do.

<Other embodiments>
Next, another embodiment will be described with reference to FIGS. FIG. 13 is an explanatory view showing a configuration of a downshift prevention plate 90 according to another embodiment. FIG. 13A is a front view of the hand cart 1 according to another embodiment, and FIG. These are the perspective views of the downward slip prevention plate 90 concerning other embodiment.
As described above, the lower unit 3 of the hand cart 1 includes the front plate 11 that is suspended downward from the front end of the upper plate 10 and the support plate 13 to which the rubber 15 that protrudes forward of the front plate 11 is attached. The lower slip prevention plate 90 is provided at the center of the lower end of the front plate 11 and below the support plate 13.

The lower slip prevention plate 90 includes a receiving plate 91 projecting forward and a trapezoidal mounting plate 92 extending upward from the rear end of the receiving plate 91, as shown in FIG. It is formed in the substantially L-shaped plate shape. The receiving plate 91 has a receiving portion 91a formed in a substantially rectangular shape and a tapered tip end portion 91b provided in a pair on the left and right sides of the receiving end portion 91a. In addition, a pair of holes 92 a are formed on the left and right of the lower portion of the mounting plate 92.
The lower slip prevention plate 90 configured in this manner is detachably provided on the hand cart 1 by screwing a bolt 95 shown in FIG. 13B to the back surface of the front plate 11 through a hole 92a. Yes. In order to attach the lower slip prevention plate 90 to the hand cart 1, the lower slip prevention plate 90 is fitted so that the upper surface of the rear end of the receiving portion 91a contacts the notch portion 11a provided at the center of the lower end of the front plate 11. Then, since the back surface of the front plate 11 and the front surface of the mounting plate 92 are in close contact with each other, the bolt 95 may be screwed to the back surface of the front plate 11 through the hole 92a in this state. Thereby, the downward slip prevention plate 90 can be attached to the hand cart 1 very easily.

  FIG. 14 is an explanatory diagram showing a state in which the pachislot machine S sandwiched between the hand carts 1 according to another embodiment is lifted from the floor surface F. Here, in another embodiment, when the pachislot gaming machine S is set in the hand cart 1, it is necessary to place the pachislot gaming machine S on the lower slip prevention plate 90. However, the lower slip prevention plate 90 has the tapered tip 91b as described above, and the tip of the tip 91b has almost no thickness as shown in FIGS. Therefore, in order to place the pachislot gaming machine S on the anti-slip board 90, simply slide the pachislot gaming machine S placed on the floor surface F toward the tip 91b until it contacts the rubber 15, and the pachislot gaming machine S S can be placed on the lower slip prevention plate 90 very easily. That is, when the pachislot gaming machine S is placed on the downshift prevention plate 90, it is not necessary to lift the heavy pachislot gaming machine S. Further, in a state where the pachislot gaming machine S is placed on the downshift prevention plate 90, the rear end side of the pachislot gaming machine S is increased by the thickness of the receiving portion 91a, but the thickness of the receiving portion 91a is extremely thin (1 to 1). After that, the work of holding the pachislot machine S by the arm 50 is not hindered.

  Then, as shown in FIG. 14, with the pachislot machine S placed on the downshift prevention plate 90, the hand cart 1 (the cart body 2) is tilted rearward and lifted from the floor surface F, When transporting the gaming machine S, the downward slip prevention plate 90 can prevent the pachislot gaming machine S from shifting downward. As a result, troubles such as the pachislot machine S falling during transportation can be avoided as much as possible. Note that the down-slip prevention plate 90 is provided for the preparation of a Manga-ichi problem, and of course, if the work of placing the pachislot machine S on the down-slip prevention plate 90 is troublesome, of course, the down-slip prevention plate 90 is used. What is necessary is just to use the hand cart 1 without attaching.
