TECHNICAL FIELD OF THE INVENTION
The present invention relates to an improvement in a transportable foldable container that accommodates various components, trays and cases containing the components, transports the components by a forklift or the like, and is foldable when not in use.
[0002]
[Prior art]
Hitherto, a foldable transportable foldable container formed by a metal grid is generally well known, for example, the invention disclosed in JP-A-6-56190, that is, on It has a pair of left and right side frames and front and rear frames that are freely foldable, and forms a right-angled bent part on one of the adjacent edges of the front and rear frames and the side frame to avoid corners during assembly A foldable container (hereinafter referred to as Prior Art 1) configured to connect the front and rear frames and the side frames, and the invention disclosed in Japanese Utility Model Laid-Open No. 5-19193, that is, the underframe and the underframe A container having a lattice-shaped bottom plate attached to the upper surface of the bottom plate, two lattice-shaped front and rear walls and two lattice-shaped left and right side walls erected on the periphery of the bottom plate, wherein at least one of the wall members is provided. The lower half of the wall from the middle position in the height direction of the wall to the bottom plate And forming an opening that opens. At an upper end of the opening, a lock means for rotatably supporting a door for opening and closing the opening and for locking and unlocking the door at a closed position of the opening is provided. 2. Description of the Related Art Foldable containers for transportation (hereinafter, referred to as prior art 2) are known.
[0003]
[Problems to be solved by the invention]
The transportable foldable container according to the prior art 1 is intended to prevent the container loaded in the upper stage from being shifted with respect to the container in the lower tier when the container is loaded in a folded state. It is not intended to prevent displacement of the container, but is performed only in the left-right direction. On the other hand, the displacement of the container that actually occurs is caused by external forces from various directions. It was almost impossible to prevent.
[0004]
On the other hand, in the folding container for transport according to Prior Art 2, the left lattice plate and the right lattice plate (4) have a configuration in which a U-shaped ring provided at a lower end thereof is inserted into an engagement hole. Since the U-shaped ring is always subjected to a load in the direction of pulling out due to gravity, if it becomes necessary to tilt the transportable folding container during use of the transportable folding container, In some cases, the left or right lattice plate was lifted off the bottom lattice plate due to the above operation, and the contents were spilled or damaged.
[0005]
The present invention has been made in view of the above circumstances, and the container stacked in the upper stage and the container in the lower stage during folding and stacking do not relatively shift in the entire horizontal direction, and the stacking is stably performed. An excellent transport fold that is easy to fold, does not inadvertently come off the grid plate during use, and is extremely easy to assemble when folded from use. The challenge is to provide containers.
[0006]
[Means for Solving the Problems]
A base frame having legs at four corners, a bottom grid plate attached to the upper surface of the base frame, a front grid plate and a rear grid plate connected with the front and rear ends of the bottom grid plate as pivot axes, and the rear grid A left lattice plate and a right lattice plate that are connected with the left and right ends of the plate as pivot axes, and the free ends of the left lattice plate and the right lattice plate are aligned with both side edges of the front lattice plate to form a box. At the lower end of the left lattice plate and the right lattice plate, a hook portion formed by extending claws forward or backward is provided at the lower end of the left lattice plate and the right lattice plate. The left lattice plate and the right lattice plate move in the front-rear direction while being connected to the metal member forming the bottom lattice plate, and the hooks are engaged with each other. Left grid plate and right grid plate (removably locked to prevent lifting) Containers, and means for solving the problems.
[0007]
In addition to the above configuration, the lower ends of the front lattice plate and the rear lattice plate are bent or curved inward to form curved bottoms (20) and (50), respectively, and the maximum width of the leg is set to the unit of the lattice. By making the width smaller than the width, each leg fits in the lattice of the front lattice plate or the rear lattice plate when folded and loaded, thereby preventing displacement in all horizontal directions. Tatami containers are the means to be solved.
[0008]
【The invention's effect】
According to the folding container for transport according to the present invention, a hook portion extending forward or rearward is provided at the lower end of the left lattice plate and the right lattice plate, and the left lattice plate and the right lattice plate are upward and By moving in the front-rear direction, the lattice of the bottom lattice plate and the hooks are releasably locked, and the left lattice plate and the right lattice plate can be prevented from being lifted. The grid plate can be prevented from accidentally coming off.
[0009]
In addition, by the same configuration, when folding, the left and right lattice plates are moved forward or backward and lifted up, so that the left and right lattice plates are easily removed from the bottom lattice plate. Since the left lattice plate and the right lattice plate can be folded in a state in which the hooks do not contact the bottom lattice plate, the transport folding container can be easily folded without turning the rear lattice plate backward. Can be folded.
[0010]
Further, by bending the lower end portion of the rear lattice plate to provide a curved bottom portion and not forming a lattice cell at the rear lowermost ends of the left lattice plate and the right lattice plate, the rear lattice plate can be folded at the time of folding operation. It is possible to prevent the bent bottom standing vertically with respect to the lattice plate from contacting with the left lattice plate and the right lattice plate, and to perform the folding operation more smoothly.
[0011]
In addition, the lower ends of the front lattice plate and the rear lattice plate are bent or curved inward to form curved bottoms, respectively, and the maximum width of the legs is made smaller than the unit width size of the lattice, so that when folded and loaded. In the case where each leg of the stacked upper container is fitted into the curved bottom portion of the lower container at the time of loading, the inner one of the front-rear direction and the left and right with respect to the leg is Metal wires constituting the lattice are arranged in a total of three directions, function as stoppers to prevent displacement, and in the outer direction of the left and right, the metal wires in the inner direction of the other legs function as stoppers In addition, the containers stacked in the upper stage and the containers in the lower stage during loading can be stably stacked without being relatively shifted in the entire horizontal direction.

[0013]
As shown in FIGS. 1 to 6, the transportable foldable container according to the first embodiment of the present invention includes two outer frames 61 each having a longitudinally continuous groove 64 arranged in parallel on the left and right sides. A base frame 6 formed by bridging three mutually parallel inner frames 62 between two outer frames 61 and further providing a leg 60 on a lower surface near an end of the outer frame 61; A bottom lattice plate 1 welded to the upper part of the frame 6, a front lattice plate 2 and a rear lattice plate 2 connected by connecting metal members 8a each formed by winding a thin metal plate around the front and rear ends of the bottom lattice plate 1 as rotation axes. It is composed of a lattice plate 5 and a left lattice plate 3 and a right lattice plate 4 which are connected by connecting metal fittings 8b around the left and right ends of the rear lattice plate 5 as pivot axes.
[0014]
At the time of manufacturing, as shown in FIG. 4, the connected left lattice plate 3, rear lattice plate 5, and right lattice plate 4 are sequentially attached to the bottom lattice plate 1, and as shown in FIG. And the free end of the right lattice plate 4 is made to match the both ends of the front lattice plate 2 to form a box-like body. As shown in FIG. At the lower four corners of the bottom lattice plate 1, the guide frame 7 is fixed to the end of the base frame 6 and the metal wire of the bottom lattice plate 1 so as to cross diagonally. The legs 60 are fixed to the lower corners of the four corners. Each of the bottom lattice plate 1, the front lattice plate 2, the rear lattice plate 5, the right lattice plate 4, and the left lattice plate 3 is a plate-like body formed of a lattice of metal wires.
[0015]
The front lattice plate 2 connects the lower end of the upper lattice plate 24 and the upper end of the lower lattice plate 25 with a coil spring 21 and a connection fitting 8c, and the upper lattice plate 24 rotates about the coil spring 21 with respect to the lower lattice plate 25. On the left and right sides of the upper lattice plate 24 and the lower lattice plate 25, the front lattices are provided together with U-shaped rings 31a and 41a provided at the center and upper portions of the front side edges of the left lattice plate 3 and the right lattice plate 4. A locking device 22 for fixing the plate 2 is mounted. The lock device 22 is generally used in a transportable foldable container including a lattice, and includes a lock rod 23 for fixing the front lattice plate 2 and a grip unit integrally attached to the lock rod 23. After the U-shaped rings 31a and 41a of the left lattice plate 3 and the right lattice plate 4 are passed through the lattice of the front lattice plate 2, the locking rod 23 of the lock device 22 is provided. Are passed through the U-shaped rings 31a, 41a, and the gripping portion of the lock rod 23 is fixed by fixing means, thereby holding the front lattice plate 2 in a connected state with the left lattice plate 3 and the right lattice plate 4. . When the U-shaped rings 31a and 41a are passed through the lattice of the front lattice plate 2, the side surfaces of the metal wires constituting the U-shaped rings 31a and 41a and the side surfaces of the metal wires constituting the lattice of the front lattice plate 2 The U-shaped rings 31a, 41a and the lattice of the front lattice plate 2 are fixed by the repulsive elasticity and frictional resistance of the metal wires when the metal wires come into contact with each other.
[0016]
Further, the lower end of the lower lattice plate 25 in the front lattice plate 2 forms a bent bottom portion 20 which is bent at a right angle in the rearward direction. It should be easy to stand upright. As shown in FIG. 6, the front lattice plate 2 is configured such that the metal wire 94 at the lowermost end is not the metal wire 10 which is the frontmost edge position in the bottom lattice plate 1, but is located at a position closer to the edge position. It is rotatably connected to the metal wire 11 on the inside by using a connection fitting 8a.
[0017]
Although not shown in detail, the rear lattice plate 5 also has a configuration in which, as in the case of the front lattice plate 2, the lower end is bent at a right angle to the front side to form a curved bottom portion 50, and the lowermost end is formed. The metal wire of the above is rotated not by the metal wire at the rearmost edge position of the bottom lattice plate 1 but by the metal fittings inside the edge position using the connecting metal fitting 8a. Connected as possible.
[0018]
By attaching the front lattice plate 2 and the rear lattice plate 5 to the metal wire rod inside the edge of the bottom lattice plate 1 as described above, it is possible to prevent the curved bottom portion 20 from abutting on the bottom lattice plate 1. The lattice plate 2 and the back lattice plate 5 can be in a state of standing vertically.
[0019]
As described above, the left lattice plate 3 and the right lattice plate 4 are provided at the center and upper portions of the front side edges of the left lattice plate 3 and the right lattice plate 4 for the purpose of connecting with the front lattice plate 2 for the purpose of U-ring. 31a, 41a are provided, and hooks 30, 40 are formed at the lower ends of the left grid plate (3) and the right grid plate (4) with hooks 30, 40 formed with metal wires in the rearward direction. The bases of the base plates 30 and 40 are fixed to the left grid plate 3 and the right grid plate 4.
[0020]
That is, as the connecting means provided at the lower ends of the left lattice plate 3 and the right lattice plate 4, the U-shaped rings 31a and 41a are always loaded in the direction of pulling out by gravity, and are applied to the U-shaped rings 31a and 41a. The metal wire rod that comes into contact with the metal wire cannot be sufficiently fixed by the elastic repulsive force and the locking force due to frictional resistance. The right grid plate 4 is lifted off the bottom grid plate 1 and may come off and overflow the contents or may be damaged. This is excluded. In the present invention, the left grid plate 3 and the right grid plate 4 are removed. Hooks 30 and 40 fixed to the lower end of the bottom grid plate and capable of being locked to the metal wire rod of the bottom grid plate 1, and a left grid plate 3 and a right grid plate 4 for engaging and disengaging the hook portions 30 and 40. By providing a moving mechanism, the folding container for transportation Left grid plate 3 or the right grid plate 4 is assumed without departing inadvertently from the bottom grid plate 1 during use.
[0021]
The movement mechanism of the left lattice plate 3 and the right lattice plate 4 is such that the rear lattice plate 5 pivots so as to slightly fall forward with its lower end as an axis. And the right lattice plate 4 slides upward.
[0022]
The sliding of the left lattice plate 3 and the right lattice plate 4 in the up-down direction is enabled by using the connection fitting 8b having a length smaller than the unit lattice dimension. Is located at a position where the lower end thereof is in contact with the upper side surface of the metal wire which becomes the weft, and the upper end of the connection fitting 8b is not in contact with the metal wire. The left lattice plate 3 or the right lattice plate 4 can be lifted up to a position where the left lattice plate 3 or the right lattice plate 4 is brought into contact with the metal wire rod. 3 and the hooks 30 and 40 of the right lattice plate 4 can be moved. In this manner, the hook portions 30 and 40 are inserted into the grooves 64 of the outer frame 61 and at positions between the lattices of the bottom lattice plate 1, and the curved bottom portion 50 of the rear lattice plate 5 is placed on the bottom lattice plate 1. When the rotation operation is returned to the original state, the rear lattice plate 5 becomes perpendicular to the bottom lattice plate 1 and the left lattice plate 3 and the right lattice plate 4 are moved, as shown in FIG. The hook portions 30 and 40 are configured to be engaged with metal wires provided in the left and right direction of the bottom lattice plate 1.
[0023]
Further, in order to engage the hook portions 30 and 40 of the left lattice plate 3 and the right lattice plate 4 with the metal wires of the bottom lattice plate 1, the left lattice plate and the right lattice plate are slid in the front-rear direction. In the state where the metal wire of the rear lattice plate and the metal wire of the right lattice plate or the left lattice plate are connected, a gap (so-called "play") is formed in the connection fitting as shown in FIG. When the left lattice plate 3 and the right lattice plate 4 are slid forward, as shown in FIG. 21, the metal wire of the rear lattice plate and the metal wire of the right lattice plate or the right lattice plate are separated by the gap. The sliding distance can be obtained only by the distance approaching.
[0024]
In the first embodiment, in addition, U-shaped rings 31b and 41b are provided at the lower ends of the left lattice plate 3 and the right lattice plate 4 for the purpose of connection with the bottom lattice plate 1.
[0025]
Further, in each of the left lattice plate 3 and the right lattice plate 4, a mesh formed by a metal wire is not formed at the rearmost lowermost portion. With this configuration, it is possible to prevent the bending operation from being performed smoothly due to the contact between the curved bottom portion 50 of the rear lattice plate 5 and the left lattice plate 3 and the right lattice plate 4 due to the deflection of each lattice plate. To do that.
[0026]
FIGS. 11 to 18 are simplified diagrams showing only the mutual relationship between the lattice plates, and explanatory diagrams showing the relationship between the hook portions 40 and the bottom lattice plate in Embodiment 1 of the present invention having the above configuration. The assembly of the transportable foldable container from the folded state during use will be described with reference to FIG.
[0027]
First, the front lattice plate 2 is raised in a state where the upper lattice plate 24 of the front lattice plate 2 in the folded transportation folding container shown in FIG. As shown in FIG. 12, the front lattice plate 2 has the curved bottom portion 20 formed at the lower end, so that the front lattice plate 2 is maintained upright on the bottom lattice plate 1.
[0028]
Then, the rear lattice plate 5, the left lattice plate 3, and the right lattice plate 4, which are connected to each other, are raised as shown in FIG. 13, and from that state, as shown in FIG. Slide up.
[0029]
Here, as shown in FIG. 19, the relationship between the hook portion 40 and the bottom grid plate in the right grid plate, U-shaped rings 31b and 41b provided at the lower ends of the left grid plate 3 and the right grid plate 4 and the hook portion 30, As shown in FIG. 15, the left lattice plate 3 and the right lattice plate 40 are inserted downward into the grooves through the lattices on the left and right ends of the bottom lattice plate 1 located on the grooves 64 of the outer frame 61, as shown in FIG. Then, the hooks 30 and 40 are engaged with the metal wire of the bottom lattice plate 1 while sliding the left lattice plate 3 and the right lattice plate 4 backward as shown in FIG.
[0030]
Finally, the upper lattice plate 24 of the front lattice plate 2 is raised, and the locking devices 22 provided on the left and right edges of the front lattice plate 2 and the center part and the upper part of the front end of the left lattice plate 3 and the right lattice plate 4 are provided. The provided U-shaped rings 31a and 41a are connected.
[0031]
The folding operation of the assembled transportable foldable container can be performed by reversing the above procedure. That is, the work of folding the assembled transportable foldable container firstly includes the locking devices 22 provided on the left and right edges of the front lattice plate 2, the central portions of the front ends of the left lattice plate 3 and the right lattice plate 4, and the like. The U-shaped rings 31a, 41a provided at the upper part are removed, the upper lattice plate is folded forward, and then the left lattice plate 3 and the right lattice plate 4 are slid forward to form the metal wire and the hook portions 30, 40. Then, the left lattice plate 3 and the right lattice plate 4 are removed from the bottom lattice plate 1 by lifting the left lattice plate 3 and the right lattice plate 4 upward.
[0032]
Then, after the left lattice plate 3 and the right lattice plate 4 are superimposed on the rear lattice plate 5 from the front, the rear lattice plate, the left lattice plate, and the right lattice plate are folded forward to be folded. It is folded down. Therefore, the rear lattice plate can be easily folded without inclining backward.
[0033]
When the tip of the forklift is inserted between the legs 60 of the folding container for transport, the tip of the forklift does not directly hit the legs, and the guide frame 7 provided at the lower portion of the bottom lattice plate 1 does not directly contact the legs. By guiding between the legs 60, the legs 60 are prevented from being deformed.
[0034]
Further, the lower ends of the front lattice plate 2 and the rear lattice plate 5 are bent inward to form curved bottoms 20 and 50, respectively, and the maximum width of the leg 60 is made smaller than the unit width of the lattice.
[0035]
As shown in FIG. 10, the leg portion 60 has a flat heel portion 65 suitable for ground contact and a hook portion 66 that is recessed continuously from the heel portion 65, as shown in FIG. 10. As shown in FIGS. 8 and 9, when folded and loaded, the heel portion 65 of each leg 60 of the stacked upper container fits into the curved bottom portions 20 and 50 of the lower container during loading. In this case, the metal wires 90, 91, 92 of the front lattice plate 2 or the rear lattice plate 3 forming a lattice with respect to the leg portion 60 in one of the inner directions of the left-right direction and the front-rear direction. Is arranged, and functions as a stopper for preventing displacement.
[0036]
Note that, in the outward direction in which the lattice is not arranged with respect to the leg portion 60, the metal wire 90 in the inward direction of the other leg portion 60 functions as a stopper, and is eventually stacked on the upper stage at the time of loading. Thus, the stacked containers can be stably stacked without any relative displacement between the container and the lower container in the entire horizontal direction.
[0037]
In the first embodiment, the curved bottom portion 50 of the rear lattice plate 5 is placed on the left lattice plate 3 and the right lattice plate 4 at the time of folding. When the rear lattice plate 5 is placed on the left lattice plate 3 and the right lattice plate 4, the rear lattice plate 5 can be made horizontal with respect to the ground plane by placing the rear lattice plate 5 on the left lattice plate 3. The folding containers for transportation in a tatami state can be stably stacked with the front, rear, left and right directions aligned in the same direction.
[0038]
In the present invention, the hooks 30, 40 in the first embodiment may be replaced with U-shaped rings 31b, 41b, and the U-shaped rings 31b, 41b may be replaced with the hooks 30, 40.
[0039]
Next, as shown in FIGS. 22 and 23, the transportable foldable container according to the second embodiment of the present invention has the same basic configuration, assembling, and usage method as in the first embodiment, and includes a left lattice plate. 3 is different from the lower lattice plate 4 in the configuration of the lower end. That is, as shown in FIG. 23, the transportable foldable container according to the second embodiment replaces the U-shaped rings 31b and 41b provided at the lower ends of the left lattice plate 3 and the right lattice plate 4 in the first embodiment. The configuration is such that the hook portions 30 and 40 are attached.
[0040]
Further, as shown in FIGS. 22 and 23, the front lattice plate 2 and the rear lattice plate 5 are provided on the curved bottom portions 20 and 50 of the front lattice plate 2 and the rear lattice plate 5 of the folding container for transport according to the second embodiment. The reinforcing wires 26 and 51 for preventing the twisting of the wire are welded.
[0041]
The folding container for transport according to the second embodiment locks the hooks 30 and 40 to the metal wires of the bottom lattice plate 1 at a total of four places by the configuration. In addition to the various effects of 1, the lifting prevention function of the left lattice plate 3 and the right lattice plate 4 can be further improved, and a more excellent folding container for transportation can be obtained.
[0042]
In addition, as the connecting body in the present invention, in addition to the connecting fittings 8a, 8b, 8c formed by the metal members disclosed in the first and second embodiments, an annular body made of a synthetic resin can also be used.
[0043]
The curved bottom portions 20 and 50 may be formed by bending the front lattice plate 2 or the rear lattice plate 5 or may be provided in a curved shape. In the case where the bent bottom portions 20 and 50 are formed by bending as in the first and second embodiments, the front lattice plate 2 or the rear lattice plate 5 standing upright with respect to the bottom lattice plate 1 is difficult to fall down carelessly. , Can be excellent.
