Hereinafter, a second embodiment of the present invention will be described. In addition, the thing similar to 1st embodiment attaches | subjects the same numbering, and abbreviate | omits description.
As shown in FIG. 6, the transport carriage 24 of the second embodiment includes a frame portion 2, a fixing portion 19, an operation portion 20, a lid portion 21, a torsion coil spring 6 and a turning caster 7.

  As shown in FIG. 6, the frame portion 2 has a bowl shape as in the first embodiment, and includes a plurality of frame skeleton members 8, a frame reinforcing member 9, a side surface mounting portion 10, and a back surface mounting portion. 11 and the slide portion 18, the frame reinforcing plate 25 is disposed on the back side and the side surface of the frame portion 2.

  As shown in FIGS. 6 and 7, the fixing portion 19 has a cylindrical shape and is open at both ends in the axial direction. A slit-shaped opening 27 for operation along the axis is provided on the side surface of the fixed portion 19. A fixing opening 28 is formed along the circumferential direction of the fixing portion 19 on the upper end side in the longitudinal direction of the operation opening 27. Specifically, the fixing opening 28 is arranged on the upper side of the operation opening 27 as shown in FIG. The fixing opening 28 is located at a position where the lid portion 21 can be maintained at a predetermined angle by engaging with the operation portion 20.

  As shown in FIGS. 6 and 7, the operation unit 20 includes a tension bar 22 and a grip part 23. The tension rod 22 is a linear rod-shaped member, and the gripping portion 23 is a rod-shaped member that is integrally joined to one end side of the tension rod and arranged perpendicular to the tension rod 22. Further, the tension bar 22 is accommodated in the cylinder of the fixed portion so that it can move relative to the fixed portion 19. Specifically, when the lid portion 21 is in the closed state, most of the tension bar 22 is stored in the cylinder of the fixed portion 19, and when the lid portion 21 is in the open state, most of the tension rod 22 is stored. This part protrudes from the inside of the cylinder of the fixed part 19 in the axial direction of the fixed part 19. The grip portion 23 can be engaged with the fixing opening 28 of the fixing portion 19, and the lid portion 21 can be fixed at a predetermined angle.

The lid 21 can be lightly opened and closed by the repulsive force of the spring. Specifically, the torsion coil spring 6 is connected to the lid portion 21 on one end side and the frame portion 2 on the upper back side to the other end side, and the elastic force works by the torsion action of the coil portion wound in a coil shape. Are biased in opposite directions.

  The operation of the operation unit 20 when the lid 21 is opened and the operation unit 20 is engaged with the fixed unit 19 will be specifically described with reference to the drawings.

  By pushing up the grip portion 23 upward, the operation portion 20 pushes the lid portion 21 around the torsion coil spring 6 and the hinge portion 17 as a fulcrum, and the lid portion 21 opens. When opening, the repulsive force of the torsion coil spring 6 acts in the opening direction, and the force is assisted. When the lid portion 21 is opened to a predetermined opening degree in the opening direction, the base end portion of the grip portion 23 can be engaged with the fixing opening 28 of the fixing portion 19, and the lid portion 21 can be engaged with the predetermined portion by the engagement. It becomes possible to fix with the opening (opening maintaining means). Therefore, the lid is not closed by the weight of the lid during the work, and the work can be performed safely. In addition, the position of the holding | gripping part 23 when the cover part 21 is made into an open state is about 150-170 cm from a floor surface. That is, it is possible for even a worker with a small height to operate, making it easy for anyone to open and close the lid, and providing a technique for quickly and safely performing an action of storing and taking out a product in a cart.

  In the above-described embodiment, the frame portion 2 is shown in a substantially rectangular parallelepiped shape, but the present invention is not limited to this and can be applied to many shapes. For example, the reinforcing plate may be covered on the lower surface and the side surface like a box shape.

  In the above-described embodiment, the configuration in which the torsion coil spring 6 and the hinge portion 17 are independently arranged at the connection portion between the lid portion 5 and the frame portion 2 has been described, but the present invention is not limited to this. Alternatively, the one in which the torsion coil spring 6 and the hinge portion 17 are integrated may be used.

  In the first embodiment described above, the gripping portion 13 is shown in a U-shape, but the present invention is not limited to this, as long as it has a gripping function. For example, a half donut shape may be used.

  In the first embodiment described above, the fixing portion 3 is installed on the frame skeleton member 8 at the upper leftmost stage when viewed from the front in FIG. 1, but the present invention is not limited to this, and the operation portion 4 is operated. Then, it is only necessary that the operation portion 4 and the fixing portion 3 can be engaged and the lid portion 5 can be fixed. For example, the length of the tension rod 12 and the height position of the fixing portion 3 may be arbitrarily changed.

  In the second embodiment described above, the grip portion 23 is shown as a cylindrical shape. However, the present invention is not limited to this, and it is sufficient that the operation portion 20 can be operated along the groove. For example, the grip portion 23 may be a saddle type.

  In the second embodiment described above, it is desirable that the fixing opening 28 of the fixing portion 19 is formed on the upper end side in the vertical direction (FIG. 7). However, the present invention is not limited to this, and positions different in the vertical direction. In addition, a plurality of fixing openings 28 may be formed.

  The material of the frame part 2, the fixing part 3, the operation part 4, the lid part 5 of the above-described first embodiment, the fixing part 19, the operation part 20 and the lid part 21 of the second embodiment is not particularly limited, Any material having the necessary strength may be used. For example, it is possible to use various materials different from metal materials and metals, such as a steel pipe and a steel plate. The torsion coil spring 6 is formed of a metal member having elasticity, and is preferably made of stainless steel. For example, it may be made of steel.
