Drawing shows the Example of the cart for storage and conveyance which can take in and out the back of articles | goods based on the invention described in Claims 1-4. In addition, although the Example shown in figure is the structure assembled using the resin-coated adhesive steel pipe and the joint made from a synthetic resin or metal as main materials, it is not this limitation. It can be assembled in the same way with existing metal materials.
As shown in FIGS. 1 to 5, this cart has a plan view surrounded by a back frame 1 and left and right side frames 4 and 5 connected to left and right sides of the back frame 1 by hinge joints 3. A bottom frame 2 is installed on the bottom of the frame that forms a letter shape. The bottom frame 2 is rotatably connected at its left end in the figure to a leg base 11 at the lower end of the left side frame 4 by a rotary joint 10. A hook joint 12 is attached to the right end portion of the bottom frame 2 and is positioned by being attached to a corresponding protrusion of the leg base 13 of the right side frame 5. Therefore, the bottom frame 2 can be raised in a substantially vertical posture along the inner surface of the right side frame 4 as shown in FIGS.

  Wheels 6 made of free casters are attached to the bottom corners 11 and 13 of the left and right side frames 4 and 5 at positions corresponding to the four corners of the heel in plan view, so that they can move on the floor surface. It is configured as a trolley. Further, the left end of the reinforcing bar 7 is connected to the open surface portion between the front ends of the left and right side frames 4 and 5 by a rotary joint 14 attached to the vertical pipe of the left side frame 4 so as to freely rotate in the vertical direction. Has been. The right end is detachably installed with a pin 16 inserted into a joint 15 attached to a vertical pipe of the right side frame 5 to complete the carriage. The reinforcing bar 7 can be removed from between the front ends of the right side frame 5 as shown in FIG.

In addition, as shown in FIG. 3, a rotary joint 19 on the right side of the intermediate shelf 20 in the drawing of the intermediate shelf 20 is rotatable on the horizontal pipe 18 provided at the intermediate position in the height direction of the side frame 5 on the right side. It is connected. The bracket 21 at the left end of the intermediate shelf 20 is hooked to a horizontal pipe 17 provided at an intermediate position in the height direction of the side frame 4 on the left side, and the intermediate shelf 20 is installed in a substantially horizontal posture. (Invention of claim 4).
The intermediate shelf 20 is also rotated downward about the right rotary joint 19 as shown in FIG. 4 by removing the bracket 21 from the horizontal pipe 17 of the side frame 4 as necessary. It can hang along the inner surface of the right side frame 5.

  Thus, as shown in FIG. 4, when the bottom frame 2, the reinforcing bar 7, and the intermediate frame 20 are respectively suspended, the carriage has the right side frame 5 approximately inward as shown in FIG. Rotation by 90 ° and juxtaposition along the inner surface of the back frame 1 complete the folding into a form that allows L-shaped nesting.

Next, the configuration of the back frame 1, particularly the configuration that enables the back and forth of articles to be put in and out will be described. FIG. 6 shows a rear view of the carriage, and FIGS. 7 and 8 show an operation state in which the rear of the article can be taken in and out.
As shown in FIG. 6 and subsequent figures, the rear frame 1 is composed of rear vertical pipes 30 and 30 that stand upright in parallel to both outer sides, a bottom pipe 31 connected between lower ends of the rear vertical pipe 30, and the same rear vertical pipe. An outer peripheral frame is formed between the upper end portions of 30 and an upper side pipe 32 connected to a position that is slightly larger than the outer surface of the upper horizontal frame described later and biased outward.

The upper movable horizontal frame 34 connected substantially horizontally between the rear vertical pipes 30 and 30 by the slide joints 33 and 33 slidable up and down along the rear vertical pipes 30 and 30 standing upright in parallel with the outer sides. The upper horizontal frame 35 is configured such that the lower end is fixed to the upper movable horizontal frame 34 in the horizontal direction with the lower end fixed, and the upper end vertically upright is detachably attached to the rear vertical pipe 30 at both ends. In the illustrated example, the upper lattice frame A (see FIG. 6) is assembled to the upper portion of the outer peripheral frame by four vertical lattice pipes 36 connected to each other.
In addition, in order to make an understanding of drawing easy, in FIG. 6-8, since each slide joint is painted black and the distinguishability with another joint is improved, please refer.

6 and 7, the upper horizontal frame 35 is configured such that the hooks 35a at both ends are detachable from the pins of the positioning joint 37 fixed to the upper portion of the rear vertical pipe 30. The upper lattice frame A can be moved upward along the rear vertical pipes 30 and 30 by pulling off the hooks 35a at both ends from the pins of the positioning joint 37. At this time, the upper side pipe 32 constituting the outer peripheral frame of the back frame is connected to a position that is biased outward from the outer surface of the upper horizontal frame 35 of the upper lattice frame A. There will be no hindrance to the lifting movement.
The upper lattice frame A can also be moved downwardly as shown in FIG. 8 by avoiding the hooks 35 a at both ends from the pins of the positioning joint 37.

  Next, a lower movable horizontal frame 41 connected substantially horizontally between the rear vertical pipes 30 and 30 by a slide joint 40 which can slide up and down along the vertical rear vertical pipes 30 and 30 on both outer sides, More specifically, the movable horizontal frame 41 is spaced apart in the horizontal direction. More specifically, the lower end portion of the movable lateral frame 41 is spaced apart from the vertical lattice pipe 36 constituting the upper lattice frame A with the lower end thereof being spaced apart. It is fixed to the lower movable horizontal frame 41 and penetrates vertically upward through a slide joint 42 constituting the upper movable horizontal frame 34, and its upper end slides up and down with each vertical lattice pipe 36 of the upper lattice frame A. In the illustrated example, three vertical lattice pipes 46 are connected to the intermediate horizontal frames 45 connected by the possible slide joints 43, and the lower lattice frame B ( 6 reference) are assembled.

This lower lattice frame B can also be independently lifted and moved upward by sliding the slide joint 40 of the lower movable horizontal frame 41 along the rear vertical pipes 30 and 30 as shown in FIG.
When the lower lattice frame B is moved upward as shown in FIG. 7, the one side end portion is located on the side surface at the lower end position of the slide joint 40 that connects both ends of the lower lower horizontal frame 41 and the rear vertical pipe 30. A stopper member 50, which is connected to the outer peripheral vertical pipes 4a, 5a of the frames 4, 5 and whose other end is connected to the rear vertical pipe 30, is installed and positioned (invention of claim 3). This is to avoid the danger that the upper lattice frame A and the lower lattice frame B moved upward will inadvertently fall and cause injury to the operator.
For the above purpose of use, the stopper member 50 is rotatably fitted to the outer peripheral vertical pipes 4a and 5a of the side frames 4 and 5 at one end as shown in FIG. A socket part 50a is provided, and the other side end part is provided with a substantially U-shaped fitting part 50b that is detachably bitten or attached to the rear vertical pipe 30 of the rear frame 1 to be connected.

Because of the above configuration, the cart of the present invention is configured so that both the upper lattice frame A and the lower lattice frame B constituting the rear frame 1 are connected to the rear vertical pipe 30 as shown in FIG. The opening C that can be slid upward along the line 30 and moved into and out of the back frame 1 can be formed sufficiently large. However, without moving the upper lattice frame A, only the lower lattice frame B is raised to the upper limit where the intermediate horizontal frame 45 abuts against the upper horizontal frame 35 of the upper lattice frame A, and the size necessary for taking in and out the stored articles. The opening C can be formed alone. Also in this case, the stopper member 50 is installed at the lower end position of the slide joint 40 of the lower lattice frame B.
Alternatively, as shown in FIG. 8, only the upper lattice frame A can be pushed down and moved alone to form a sufficiently large opening D through which the stored articles can be taken in and out of the upper portion of the back frame 1.

  In any moving operation, the upper lattice frame A and the lower lattice frame B of the back frame 1 are always slid and moved along the back vertical pipes 30 and 30 of the back frame 1. In other words, it is a movement in the vertical direction within the frame surface of the back frame 1, and there is no need for a dead space for opening and closing like a double door or a sliding door. Therefore, it is convenient that the back and forth of the stored articles can be freely put in and out as needed even in a narrow warehouse where cargoes are densely packed.
