A pin unit 8 comprising the above is provided.
As shown in FIGS. 3 and 4, the pallet base 1 has a locking hole 9 in which the pin 11 cannot be pulled out when the head portion 11b at the lower end of the upper and lower headed pins 11 is inserted and slid. The front plate 2 and the back plate 3 (and / or the left and right side plates 4, 5) are provided in a state where the head portion 11b at the lower end of the upper and lower headed pins 11 is inserted into the locking hole 9. It is connected to the pallet base 1 so as not to be pulled out upward.

In this embodiment, the so-called slide-type non-pullable mechanism described above is implemented for the front plate 2 and the back plate 3, but the present invention is not limited to this. For example, it can be applied only to the left and right side plates 4 and 5, or it can be applied to all four face plates 2 to 5. By the way, as for the face plates on which the slide-type non-pullable mechanism is not implemented, such as the left and right side plates 4 and 5 according to the present embodiment, for example, the face plates are substantially channel steel 1b according to a conventionally known method. It is inserted diagonally into the groove of the steel (upright), and then placed vertically.

Hereinafter, in explaining an embodiment of the assembling pallet 10 according to the present invention, first, the overall configuration of the assembling pallet 10 to which the present invention is applied will be described, and then the slide-type non-pullable mechanism will be described. Further, an assembling method of the assembling type pallet 10 using the slide type non-pullable mechanism will be described.

(Explanation of Overall Configuration of Assembled Pallet 10 to which the Present Invention Applies)
The assembled pallet 10 is mainly composed of a pallet base 1, four face plates 2 to 5, and handle-type connecting devices 6 and 7.

The pallet base 1 has a substantially groove shape on all four sides of a frame frame provided with fork insertion holes for a forklift by appropriately combining a vertical member 13, a horizontal member 14, and a bundle member 15 so that FIG. 3 can be easily understood. The steel 1a (see FIG. 4B) and 1b are integrally arranged, and the bottom plate 16 is integrally arranged on the upper portion.
The bottom surface of the substantially channel steel 1a is provided with locking holes 9 at two locations in a well-balanced manner with a required interval at the center in the axial (longitudinal) direction.
The substantially channel steels 1a and 1b are provided for erecting the four face plates 2 to 5 in a stable state, and for example, an angle member (angle steel) can be used as a substitute. In short, the four side portions of the pallet base 1 are so-called fittings provided with rail portions that come into contact with the lower surfaces of the face plates 2 to 5 and side wall portions that satisfactorily restrain the sliding movement of the face plates 2 to 5 in the out-of-plane direction. Any structure may be used as long as it has a groove portion.
Further, although it depends on the transported object (stored object) of the assembly type pallet 10, it is also possible to carry out a configuration in which a thin plate material is arranged in a slatted shape instead of the bottom plate 16.

Of the four face plates 2 to 5, the front plate 2 and the back plate 3 use face plates having the same configuration in this embodiment. Therefore, when the front plate 2 is used as an example, the left and right sides are shown so that FIG. 5 can be easily understood. A steel plate 2a (four sides are indicated by dotted lines) is welded to the back side of a frame composed of side edge members 2d on both sides, two intermediate vertical members 2e, a lower edge member 2c, and an upper edge member 2b. It is implemented in a configuration that is attached by joining means.
In this embodiment, as an example, the side edge member 2d, the vertical member 2e, and the lower edge member 2c use a square steel pipe (square pipe) having the same cross-sectional shape (length 20 mm × width 20 mm × plate thickness 1 mm) and have an upper edge. The member 2b uses a square steel pipe having a cross-sectional shape (length 40 mm × width 20 mm × plate thickness 2 mm) having a larger height and plate thickness.
A pin unit 8 composed of a pin 11 with an upper and lower head and a pin support 12 is provided at two locations corresponding to the locking holes 9 and 9 in the central portion of the square steel pipe used as the lower edge member 2c in the pipe axial direction. , 8 are provided.

That is, the so-called slide-type non-pullable mechanism according to this embodiment is implemented at two locations for each of the front plate 2 and the back plate 3, but the number is not particularly limited and the design can be changed as appropriate. However, in consideration of economy, efficiency, and rationality, the arrangement and the number correspond to two places in the central part in the longitudinal direction as in this embodiment, in other words, substantially the division points when the parts are divided into three equal parts in the longitudinal direction. It is preferable to provide it in the part to be used.
The reason is that, in general, assembling pallets often carry and store heavy objects (for example, about 1 ton), and by repeatedly using them, any assembling pallet can be used in the longitudinal direction of the pallet base. There is an inherent problem that the central part bends and deforms over time, which hinders the assembly and disassembly work of the assembly type pallet, and the raw material (container) leaks from the gap between the pallet base and the face plate. However, this is because such problems can be prevented most effectively.

Next, of the four face plates 2 to 5, the left and right side plates 4 and 5 use face plates having the same configuration in this embodiment. Therefore, the right side plate 5 will be described as an example. As shown, a joining means such as welding a steel plate 5a to the back side of a frame composed of side edge members 5d on both left and right sides, one vertical member 5e in the middle, a lower edge member 5c, and an upper edge member 5b. It is carried out with the configuration pasted in.
The side edge member 5d uses an angle material (length 30 mm × width 40 mm × plate thickness 2 mm), and as shown in FIG. 2, the flange portion 5d'(projection size 30 mm) in the vertical direction thereof is the front plate. It is implemented in a configuration that abuts on the outer surface of 2.
In this embodiment, as an example, the vertical member 5e and the lower edge member 5c use a square steel pipe having the same cross-sectional shape (length 20 mm × width 20 mm × plate thickness 1 mm), and the upper edge member 5b has a height and a plate thickness higher than that. A square steel pipe having a large cross-sectional shape (length 30 mm × width 20 mm × plate thickness 1.2 mm) is used. Further, the top end of the front plate 2 (upper edge member 2b) and the top end of the right side plate 5 (upper edge member 5b) have a structure in which the upper surfaces are substantially flush with each other when the assembly type pallet 10 is assembled. It is implemented by design (see Figure 2).

As an example, the size of the assembled pallet 10 is such that the width dimension of the front plate 2 and the back plate 3 in the left-right direction is about 1400 mm, the width dimension of the side plates 4 and 5 in the left-right direction is about 1100 mm, and the height from the floor surface. The pallet size is about 1000 mm. Further, the thickness of the four face plates 2 to 5 is implemented as a thin plate of about 0.35 to 0.40 mm in order to reduce the weight burden during transportation.

The handle-type connecting devices 6 and 7 are provided at the left and right upper corners of the front plate 2 and the back plate 3, and adjacent face plates 2, 5 (see FIG. 2) and the like are connected to each other by manual operation. , Provided to be assembled into a box shape with an open top surface, as shown in FIG.
Since the handle type connecting devices 6 and 7 have a common configuration (left-right symmetrical structure), the handle type connecting device 7 on the right side will be described as an example. As shown in FIG. 2, the steel plate is U-shaped in a plan view. The handle receiver 7d, which supports the latch rod 7b by the bearing member 7a formed by bending the latch rod 7b and restricts the positioning of the handle 7c extended to the latch rod 7b, is integrally formed with the bearing member 7a by a series of bending moldings. Has been done. Incidentally, reference numeral 7b'in the drawing indicates a hook portion formed at the tip end portion of the latch rod 7b, and reference numeral 7e indicates a reinforcing member (angle member).

Then, when connecting the front plate 2 and the right side plate 5, first, the front plate 2 stands on one side of the pallet base 1 by using a so-called slide-type non-pullable mechanism. Set up.
Next, the handle 7c of the handle type connecting device 7 provided on the right side of the front plate 2 is pulled by rotating it 90 degrees toward the front side from the state shown in FIG. 2, and the hook portion 7b formed at the tip of the latch rod 7b is formed. 'Position vertically.
After that, when the right side plate 5 is obliquely erected in the groove of the substantially channel steel 1b and vertically erected, the vertical direction is formed in the vertically elongated hole 5f formed in the side edge member 5d of the side plate 5. The hook portion 7b'of the steel is inserted, and the hook portion 7b' is projected out of the right side plate 5.
Next, the handle 7c is rotated 90 degrees, the vertical side portion of the handle 7c is housed in the handle receiver 7d, and the front plate 4 and the right side plate 5 are connected to each other (FIG. FIG. 2).
To release the connection between the front plate 2 and the right side plate 5, the handle 7c is rotated 90 degrees toward you from the state shown in FIG. 2 and pulled, and the hook portion 7b'is the same as the vertically elongated hole 5f. Orientation. Then, the right side plate is separated from the front plate 2 to release the mutual connection between the front plate 2 and the side plate 5.

The configuration of the assembly type box pallet 10 including the handle base 1 and the four face plates 2 to 5 is merely an example, and the present invention has a substantially box shape with an open upper surface and has a required strength. Any form can be used as long as it is a rigid assembly type box pallet. Further, the configurations of the handle-type connecting devices 4 and 5 according to the illustrated example are merely examples, and the pallet base 1 as disclosed in Japanese Patent Application No. 2015-515340, for example, which the applicant has previously applied for. Any form is acceptable as long as the adjacent face plates erected along the four sides of the above can be firmly connected or disconnected from each other.

(Explanation of the so-called slide-type non-pullable mechanism)
This slide-type non-pullable mechanism is realized by the locking hole 9 provided on the pallet base 1 side and the pin unit 8 provided on the front plate 2 (or back plate 3) side.

The locking hole 9 has a substantially keyhole shape as shown in FIG. 4, and more specifically, is wider (about 15 mm) than the outer diameter (about 13 mm) of the head portion 11b at the lower end of the upper and lower headed pins 11. It is carried out in a shape in which the portion 9a and the narrow portion 9b narrower (about 9 mm) than the diameter of the head 11b are communicated with each other. The shape of the locking hole 9 is not limited to a substantially keyhole shape, and the head portion 11b at the lower end of the upper and lower headed pins 11 such as a substantially Dharma shape (gourd shape) can be inserted and slid. The shape of the head 11b may be such that it cannot be pulled out upward.

On the other hand, the pin unit 8 provided at the portion corresponding to the locking hole 9 is composed of a pin 11 with an upper and lower head and a tubular pin support 12 so that FIGS. 7 and 8 can be easily understood.
The pin 11 with an upper and lower head has a head portion 11b (outer diameter of about 12 mm, length of about 7 mm) at the lower end, and the upper end of a pin shaft (outer diameter of about 8 mm, length of about 30 mm) is supported by the tubular pin. The head 11a (outer diameter of about 12 mm, length of about 7 mm) is screwed into the protruding upper end portion of the body 12 so as to penetrate the body 12. Further, male threads are formed on the outer periphery of the bases of the heads 11a and 11b over a length of about 3 mm.
The heads 11a and 11b are formed in a substantially hemispherical shape (convex spherical surface) having the same shape and size, but are not limited to the same shape and size. Further, the shapes of the heads 11a and 11b are not limited to a substantially hemispherical shape, but the head 11b at the lower end may be exposed (exposed) to the outside and come into contact with other members. A smooth substantially hemispherical shape suitable for avoiding damage to each other (head 11b and other members) is preferable.

The tubular pin support 12 is connected to a tubular portion 12b (with an inner diameter of about 8.2 mm) into which the pin shaft of the pin 11 with an upper and lower head can be inserted, and the upper and lower heads 12b. A diameter-expanded portion (accommodating portion) 12a capable of accommodating the lower end head 11b of the attached pin 11 and a head 11a at the upper end of the upper and lower headed pins 11 which are connected to the upper portion of the tubular portion 12b can be installed. It is provided with an enlarged diameter portion (female screw portion) 12c. Incidentally, the diameter-expanded portion (accommodating portion) 12a according to the present embodiment is implemented with a height of about 8 mm and an inner diameter of about 12.6 mm, and the diameter-expanded portion (female screw portion) 12c has a height of about 3 mm and an inner diameter of 12 It is carried out at about 0.6 mm.

As shown in FIG. 7, a predetermined portion (two locations in this embodiment) of the lower edge member 2c of the front plate 2 (or the back plate 3) on which the tubular pin support 12 is fixed is provided. Round holes into which the pin support 12 can be inserted in a vertical position are provided on the upper surface portion and the lower surface portion, respectively. The pin support 12 is fitted into the round hole, and the bottom surface of the lower edge member 2c and the annular bottom surface of the pin support 12 are aligned flush with each other (see FIG. 7 and the like) for all-around welding and the like. The pin unit 8 including the upper and lower headed pins 11 and the pin support 12 is integrally fixed to the lower edge member 2c of the front plate 2.
Thus, it is possible to realize a structure in which the pin units 8 are integrally fixed at two locations in a well-balanced manner by opening a required interval in the central portion of the lower edge member 2c of the front plate 2 in the pipe axial direction.

The pin unit 8 having the above configuration is shown when the head portion 11a at the upper end of the pin 11 with upper and lower heads is screwed into and fixed to the enlarged diameter portion (female screw portion) 12c formed on the upper portion of the pin support 12 (during use). As shown in 7B, the head portion 11b at the lower end can be maintained in a state of protruding downward from the bottom surface of the lower edge member 2c of the front plate 2. Further, when the head 11b at the lower end is screwed into the enlarged diameter portion (accommodating portion) 12a formed at the lower part of the pin support 12 and fixed (when not in use), the head at the lower end is as shown in FIG. 7A. The state in which 11b is housed inside the housing portion 12a of the pin support 12, and by extension, the lower edge member 2c of the front plate 2 can be maintained.
By the way, the screwing work related to this use and when not in use can be easily carried out by the worker simply rotating the upper end head 11a or the lower end head 11b of the upper and lower headed pins 11 clockwise or counterclockwise. it can. In this screwing operation, the worker can rotate the head 11a or the head 11b by fingers, and as illustrated by the broken line in FIG. 8B, the head 11a or the head 11b is added to the crown. Of course, it is also possible to form a recess (dent) such as a (+) hole, a minus (-) hole, a hexagonal hole, or a hexagonal star-shaped hole, and rotate it using a tool such as a screwdriver or a hexagon wrench. it can.

Therefore, according to the assembled pallet 10 according to the present invention, the head portion 11b holding the downwardly protruding state as shown in FIG. 7B is formed on the substantially channel steel 1a of the pallet base 1. When engaging with the stop hole 9, the head 11b is inserted into the wide portion 9a of the locking hole 9, and then slid to the narrow portion 9b, so that the head 11b and thus the front plate 2 (or the back plate 3) are slid. Can be erected in the locking hole 9 in a structure that cannot be pulled out (see FIGS. 7C and 7D).

(Explanation of Assembling Method of Assembled Pallet 10 According to the Present Invention)
Next, an example of an assembling method of the assembled pallet 10 having the above configuration will be described.
It should be noted that this assembly work can be sufficiently performed by one worker. Further, the procedure for attaching the face plates 2 to 5 described below is merely an example.

First, the front plate 2 is erected on one side (long side) of the pallet base 1.
In this case, as shown in FIG. 7B in advance, the head portion 11a of the upper end of the pin 11 with upper and lower heads is screwed and fixed to the enlarged diameter portion (female screw portion) 12c formed on the upper portion of the pin support 12, and the lower end is fixed. The head portion 11b of the head portion 11b is kept protruding downward from the bottom surface of the lower edge member 2c of the front plate 2 (the size of the protruding pin shaft is about 6 mm). Incidentally, in FIG. 7, the face plate 2a (the plate thickness is less than 0.5 mm) of the front plate 2 is omitted for convenience of illustration.
Then, as shown in FIG. 7C, the front plate 2 is provided with a locking hole in which the head portion 11b protruding from the lower end thereof is provided in the substantially channel steel 1a (plate thickness is about 2 to 4 mm) of the pallet base 1. It stands vertically while being inserted into the wide portion 9a of 9, and then slides toward the narrow portion 9b. By this slide operation, the head portion 11b and, by extension, the front plate 2 cannot be pulled out (retaining).

Next, the back plate 3 is erected on the pallet base 1 in a structure that cannot be pulled out by the same method as described above. As shown in FIG. 3A, the directions of the locking holes 9 formed in the corresponding substantially channel steels 1a and 1a are different. This is because it was carried out with one type of substantially channel steel 1a in consideration of economy and workability, and it is of course possible to carry out with a configuration in which the directions of the locking holes 9 are aligned.

Next, from the state in which the front plate 2 and the back plate 3 are erected in a face-to-face arrangement, the flange portion 5d'protruding the right side plate 5 in front of both ends thereof is the front plate 2 and the back. The handle-type connecting device 7 on the right side of the front plate 2 and the spine when the steel 1b is slanted in the groove of the substantially channel steel 1b and then vertically erected, taking care not to contact the face plate 3. Each handle operation of the handle type connecting device 6 on the left side of the face plate 3 (see the paragraph [0025] for details) is performed, and the flanges 5d'on both sides come into contact with the outer surfaces of the front plate 2 and the back plate 3. With a configuration that restrains the sliding movement in the out-of-plane direction, the right side plate 5 is positioned and fixed in a vertically standing state.

Subsequently, the left side plate 4 is positioned and fixed in the same manner as the right side plate 5, and as shown in FIG. 1, adjacent face plates 2 and 5 standing upright in a stable state (FIG. 1). 2) and the like are connected to each other, and a box-shaped assembling pallet having an open upper surface and a height of about 1000 mm is assembled.
As an example, the positioning of the side plates 4 and 5 and the substantially channel steel 1b of the pallet base 1 follows a conventionally known method in this embodiment and is horizontal to both ends of the substantially channel steel 1b. The dowel holes provided at both ends of the side plates 4 and 5 are fitted into the dowels (protruding portions) protruding from the surface.

Although the examples have been described above, the present invention is not limited to this, and it should be noted that the present invention includes a range of design changes and application variations normally performed by those skilled in the art without departing from the technical idea. Mention.

For example, the pin unit 8 according to the present embodiment is implemented by a screw mechanism (fixed type) in which the pin 11 with an upper and lower head is fixed to the pin support 12 with a screw, but the pin unit 8 is not limited to the fixed type. The same can be applied to a free configuration in which the head portion 11b can be taken in and out of the pin support 12 (front plate 2, etc.) without using a fixing means such as a screw mechanism.
Further, as shown in FIGS. 9A to 9D, the depth of the accommodating portion a of the pin support 12 is formed to be slightly deeper, and the head portion 11b can be freely inserted and removed from the pin support 12 (front plate 2, etc.). It can be implemented in a configuration (see FIG. 9A), and if it is desired to be fixed, it is fixed using a screw mechanism (see FIG. 9B), and a so-called two-stage configuration can also be implemented in the same manner.
Further, in the present embodiment, the so-called slide-type non-pullable mechanism is applied to the two facing face plates (front plate 2 and back plate 4) among the four face plates, but the four face plates 2 to It can also be applied to all of 5. In this case, in this embodiment, the flange portion 5d'of the side edge member (angle member) 5d provided at both left and right ends of the right side plate 5 (or the left side plate 4) interferes with the sliding operation. Therefore, for example, it is conceivable that one of the side edge members 5d is detachably mounted, or one of the flange portions 5d'is bent by using a hinge mechanism or the like.
