Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a collapsible container device used for transporting powder or liquid.

Recently, flexible containers made of tarpaulin sheets, etc. have become popular, and although flexible containers can be folded and are convenient for storage, they are not self-supporting, so they are not suitable for liquids. It has the disadvantages that it cannot be used, is unstable, has low stability even when containing powder and granules, and is prone to tipping over.

In addition, the bottom of the container is often placed in direct contact with the ground or floor, which causes the problem of being easily soiled and unhygienic.

Therefore, the present invention has been made to solve the above problem, and its purpose is to provide a folding 1110 mounted on a frame.
To provide a container device in which a flexible bag body is hung between freely adjustable support columns and the bag body can be easily folded in an attractive manner by following the operation of folding the support columns onto a stand. That is, the above-mentioned object of the present invention is to provide a container device body in which supports are erected at each of the four corners of a pedestal, and a flexible bag is suspended on the pedestal via the above-mentioned supports, and the above-mentioned supports are articulated. It is formed by joining the upper, middle, and lower pillars that can be bent to each other at the lower ends, and the lower end of the lower pillar is attached to the joints fixed to the four corners of the frame so that it can be bent freely. Adjacent upper columns are connected to each other by upper horizontal rods, and adjacent joints of the bent middle column and lower column are connected to each other by lower horizontal rods. The upper sides of the bag bodies are respectively attached to the rods, and a pair of opposing lower cross rods of the lower cross rods are removably attached to the joint where the lower cross rods are suspended. This is achieved by means of a collapsible container device, an embodiment of which will be described in detail below with reference to the accompanying drawings.

The pedestal 1 is formed into a pallet shape into which the claws of a forklift can be inserted, and pillars 2 are erected at the four corners of the pedestal 1 so as to be able to rise and fall freely.

These columns 2 are an upper column 2a and a middle column 2b1, respectively.
Consisting of three lower columns 2C, each column 2a, 2b, 2
c are bendably connected to each other by joints 3, 4.5, which will be described later. Adjacent upper columns 2a are connected to each other by upper horizontal rods 6, and from these upper horizontal rods 6, a bag body 7 made of flexible sorting such as a tarpaulin notebook is suspended. That is, the bag body 7 is suspended by adhering sleeve-shaped hanging parts 8 to the upper sides of the four sides of the bag body 7, and inserting these hanging parts 8 into the upper horizontal rods 6, respectively. On one set of the two opposing sides of the bag body 7 are provided pressing rods 9 bent into a substantially U-shape, and these pressing rods 9 are It is horizontally suspended between the left and right upper pillars 2a while being positioned below 9a.
is its supporting end.

On the other hand, the joint parts 4 of the middle column 2b and the lower column 2c are connected to each other by a lower horizontal rod 1, and a horizontal frame is mounted on the pressing rod 9 side of the lower horizontal rod 11. The lower horizontal rod 11 is detachably attached to the joint portion 4. The upper horizontal rod 6 and the lower horizontal rod 11 function as struts that hold the four columns 2 so that they can be raised and lowered. Note that hanging parts 8' similar to the hanging parts 8 are adhered to the upper sides of the four sides of the bag body 7, if necessary, and these hanging parts 8' are inserted into the lower transverse rods 11.

Next, the configurations of each joint portion 3+'+5 and the pressing rod 9 will be explained in sequence.

First, the cross-sectional shape of the joint 3H between the upper column 2a and the middle column 2b is a U-shape that opens inward (the open surface is 3a
, ), and the lower end of the upper column 2a and the upper end of the middle column fit into this joint 3 so that they can rotate relative to the upper column 2a fixed to the joint 3. middle column 2
b is attached with 12 shafts (using bolts, etc.). The joint 4 between the middle column 2b and the lower column 2C is a metal fitting with a U-shaped cross section that opens outward (the open surface is 4 a'). The lower end of the middle column 2b and the upper end of the lower column 2C are fitted together, and the lower column 2C is attached to a shaft (using a bolt, etc.) so that it can rotate relative to the middle column 2b fixed to the joint 4. ) He finished 13th. However,
The joints 5 for the lower end of the lower column 2C are metal fittings each fixed to the four corners of the pedestal 1 and have a substantially U-shaped cross-section opening inward (the open surface is 5a). The lower end of the lower column 2C is fitted into the joint 5 and rotatably attached to the shaft 14 (using a bolt or the like). In addition, several push-up elements 15 are provided in the joint portion 5 so as to be able to rise and fall freely.
The support shaft 17 attached to the joint part 5 is inserted into the frame 1.
When the frame 1 is suspended, the pusher 15 slightly protrudes from the lower surface of the frame 1. Therefore, when the pedestal 1 touches the ground, the pusher 15 rises by a distance corresponding to the protruding portion, and its slanted upper end surface 15a
The mechanism is such that a moment can be generated that pushes up C and rotates the lower column 2C inward. In addition, each of the above-mentioned +1Ill+ 12, +:U, 111 corresponds to the upper and lower axes 12. when the partial column 2a, middle column 21] and lower column 2c extend straight as shown in FIG. II
Although it is located on the J-knee straight line, the intermediate shaft 13 is located at a position offset to the north right in the figure, and when the pedestal 1 is suspended with the removable lower crossbar mentioned above removed. -, each axis 12.13. lll are located on a straight line.

That is, when the respective axes 12, 13, and 14 are located on a straight line, the middle column 2b and the lower column 2C are slightly bent inward by their own weight (state of imaginary lines).

As shown in FIG. 4, the pressing rod 9 has both supporting ends 9
af: Supported by being rotatably inserted into support tubes 18 protruding from the left and right upper columns 2a, and a coil spring 1 is inserted between the support tubes 18 and the support end 9a.
9 is attached, the pressing rod 9 is placed under the action of a spring that constantly heats the bag body 7 side, and the bag body 7 is constantly pressed from two sides. The tip ViF1 of the support end 9a has a rectangular cross-sectional shape, and the narrow diameter portion 49a of the coil/neck 19 fits into this tip, and the other end 19b of the coil/neck 19 fits into this tip. The support tube 18 is hooked.

According to the configuration described above, the four upper horizontal bars 6 are mounted on the pedestal 1.
When the bag body 7 is suspended under the load, the bag body 7 is prevented from swinging by at least the lower cross member 11, and is kept in an extremely stable suspended state. , it is possible to ensure safety during transportation and storage work, and it is
Since the bottom (discharge port side) of the bag body 7 is not grounded, there is no need to worry about it getting dirty, and it can be used hygienically even in the case of powder or liquid.

On the other hand, when the load is empty, the mount 1 is moved to the forklift 1. A
When a pair of lower horizontal rods 11 facing each other are removed from the joint portion 4 while suspended by fp, each column 2a, as described above, appears:
The respective axes 12°13.111 serving as fulcrums of the shafts 2b and 2c are located on a straight line, and the middle pillar 2b and the lower pillar 2c are automatically held in a slightly bent state. Therefore, when the pedestal 1 touches the ground in this state, as described above, the lower column 2C receives a lateral force that causes it to rotate further in the bending direction by the two pins 15, and at that point the pedestal cannot be suspended. When unraveled, this container device can finally be folded one by one into the form shown in FIG. 2 by its own weight. in this case,
The pressing rod 9 uses a spring action to press the two opposing faces of the bag 7 toward each other, so that when the bag 7 is folded, the bag 7 is held up by the support 2. It eliminates any problems when pinching the bag and allows it to be neatly folded onto the rack/stand 1, completely eliminating the risk of damaging the bag 7 during transport or storage. can.

In addition, in the figure, 21 and 22 are horizontal rods protruding from the upper column 2a and the joint 4, respectively, and 2=l(d) are the hanging pestles horizontally suspended between the upper column 2a. The hanging hook provided on the top, 25 is an input port, and 2G is a discharge port.

The present invention is as described above, and not only can the bag be maintained in a stable upright state at all times, but the bottom part of the bag does not have to be dragged directly onto the ground or floor, so it is protected from dirt and damage. It can be protected and used hygienically, and the folding operation can be easily performed by simply removing a pair of opposing lower transverse rods.In addition, it has operational advantages. Its practical value is extremely great, as the bag has an excellent retention function and can be used economically for a long period of time.
