An article carrier.

  According to the article transport machine of the present invention, in a state where the article is placed on the article placement table, the moving belt body is placed along the corner edges of each step of the stairs, with the operation part for stair movement upward. When the drive unit is operated, the moving belt body is moved in a state of being bitten by the corner edge of each step, and the article transport machine moves up and down along the stairs to transport the articles.

  The configuration in which the article placement table and the moving belt body are folded in an overlapping manner on the base body provides a compact form when not in use, which facilitates handling and does not take up space for storage.

  The moving belt body is configured such that the driving portion is composed of an electric motor and a battery serving as its power source, and a heavy battery is provided on the front side of the lower end of the vertical portion of the base body on the lower surface of the article conveying machine. Even in a structure in which the upper part of the is inclined backward, it is stably installed and used without falling back.

  By using the article transport device of the present invention, it is possible to easily and safely transport articles on the stairs.

Embodiments of the invention

  FIG. 1 is a front side perspective view of an article conveying machine according to the present invention, and FIG. 2 is a rear side perspective view thereof. The article transfer machine 1 has a rectangular frame shaped vertically arranged base body 2 having casters 3 at both ends in the lower portion, an arch shaped stair movement operation unit 5 provided on the upper portion of the base body 2, and a base body 2 The lower end of the lower body is provided with casters 7 at both ends on the front side of the lower surface, and the lower portion is rotatably supported at the rear lower portion of the base body 2 and the upper portion is mounted rearward It comprises a pair of moving belt bodies 11 provided in an inclined manner, an electric motor 13 for driving the moving belt body 11, and a battery 60 serving as the power source for the electric motor 13.

  The article transport machine 1 is horizontally moved in a state where the caster 3 and the caster 7 are in contact with the ground, and the article is transported on a flat surface. As for the conveyance in the stairs, the belt body 11 for movement is made into the state along the corner edge of each step of stairs with the operation part 5 for step movement as the upper side, and the movement belt body 11 is Working displacement is carried out while biting at the corner edge of the step, whereby the article transport machine 1 is moved up and down along the stairs.

  FIG. 3 shows a state in which the article transport machine 1 is not in use. The article placing table 9, the moving belt 11, and the handle 19 are folded in an overlapping manner on the base 2, and the moving operation unit 5 is in a contracted state, so that the whole is in a compact form While handling at the time of use is made easy, the storage space can be made small.

  As shown in FIG. 4, the article mounting table 9 is provided with a connection fixing pin 15 attached to the connection block 14 at the back end of the lower surface thereof by being biased rearward by a spring to the connection block 14. Are connected to one another on the proximal end side by an operating rod 17. When the operation rod 17 is pulled forward (in the direction of arrow A) and each of the connection fixing pins 15 is separated from the base 19 of the base body 1, the article mounting table 9 is folded in the side of the base body 2 (in the direction of arrow B). .

  As shown in FIG. 5, at the upper part of the longitudinal bars 16 on both sides of the base body 2, each of the handle parts 19 used when being moved horizontally is provided so as to protrude rearward by the attachment member 21. . The handle 19 is mounted on the mounting member 21 fixed to the longitudinal bar 16 so as to be pivoted upward by a spring force and maintained in the horizontal state, and the lever 23 is pushed down to release the internal lock. It is pivoted in the direction of arrow C to be in a folded state, and is further locked upward by being pivoted back to the upper side, and is in a horizontal state.

  An operating lever 27 is rotatably attached to the inner side surface of each mounting member 21, and the lower ends of the operating levers 27 of the opposing mounting members 21 are connected by an operating bar 29. The actuating lever 27 is attached by being biased by a spring in a direction in which the upper end is pivoted in the forward direction (arrow D), and a lock pin 31 projecting from the inside of the mounting member 21 is attached to the upper end member 26. The lock pin 31 is inserted into the lock holes 37 provided at two heights of the pipe 35 of the operation portion 5 for movement located in the vertical beam 16 of the base body 2 by biasing of the spring, thereby moving The operation unit 5 is fixed at two positions that expand and contract. When the operation lever 29 is pushed in (in the direction of arrow E) and the operation lever 27 is rotated, the lock pin 31 is disengaged from the lock hole 37, and the extension operation of the movement operation unit 5 becomes possible.

    As shown in FIG. 2, the pair of moving belt bodies 11 are connected and fixed to each other by the fixing rod 41 at the upper and lower positions, and guide grooves 43 are provided halfway from the lower part of the respective opposite inner surfaces. The guide rod 45 is provided with its both ends locked in the guide groove 43 of FIG. Link members 47 are attached by being pivotally supported on the vicinity of the end portion of the guide rod 45 and on the side surface of the longitudinal bar 39 of the base body 2 respectively. As shown in FIG. 6, a locking piece 48 provided with a locking projection 46 is provided at the lower end of the link member 47 on one of the moving belt members 11 side.

  An air cylinder 51 is provided in the lower portion in one of the transfer belts 11, and one end of a guide rod 45 is connected to an end of an operation piece projecting from the upper portion of the air cylinder 51. In addition, a locking member 56 is attached to the side closer to the one moving belt body 11 of the lower fixed rod 41. The locking member 56 is composed of a horizontal portion 55 and a vertical portion 57. The bent portion is pivotally supported to be spring-biased (in the direction of the arrow F). The vertical portion 57 is provided with a locking hole 59. It is done.

  In the state in which the transfer belt body 11 shown in FIG. 3 is folded, as shown in FIG. 6, the locking projection 46 of the locking piece 48 is fitted into the locking hole 59 of the locking member 47 and locked. In this state, the folded state of the moving belt body 11 is maintained. By pushing the horizontal portion 55 of the locking member 56 downward against the spring force, the vertical portion 57 is displaced inward, and when the locking projection 46 is released from the locking hole 59, the moving belt body 11 is at the top Is inclined and displaced by its own weight, and the state shown in FIGS. 1 and 2 is obtained, and the state is fixed and maintained by the guide rod 45 and the link member 47. The inclination displacement of the moving belt body 11 described above is gently performed by connecting one end of the guide rod 45 to the end of the actuating piece of the air cylinder 51. In the state shown in FIG. 2, the moving belt 11 is closed by stepping on the guide rod 45 (in the direction of the arrow G), and the locking projection 46 is automatically fitted and locked in the locking hole 59.

  The motor 13 is attached to the lower portion between the pair of moving belts 11, and the drive shaft and the lower pulley in the moving belt 11 are geared to move the moving belt 11. Reference numeral 60 denotes a battery for driving, which is attached to the lower surface of a mounting bar 61 provided to project forward from the lower end of the vertical portion of the base body 2. By providing the heavy battery 60 at this position, the article transport machine 1 can be stably installed without being tilted backward in the state of FIGS. 1 and 2 in which the moving belt 11 is inclined.
