DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holding frame used for a transport pallet used to prevent cargoes stacked on a transport pallet, such as bottles and cans, from collapsing. .

[0002]

2. Description of the Related Art Conventionally, bottles and cans of beer, soft drinks and the like are transported, especially in the case of one-way bottles, which are transported in a stack on a transport pallet. An example of transporting a one-way bottle will be described with reference to FIG. 8. A large number of one-way bottles are arranged on the bottle 4, and the bottles 3 are alternately stacked in a multi-stage manner via the cardboard 4. And the top cardboard 4
A holding frame 5 having substantially the same size as the transport pallet is placed on the pallet, and a band 6 is hung over the holding frame 5 and fixed.
Finally, a heat-shrinkable film 7 such as a polyethylene film is put on while being fixed with the band 6, and wrapped. In this way, the bottles are transported by stacking the bottles on a transport pallet and packing the entire bottle.

[0003] The position where the band 6 is passed over the holding frame 5 is
Usually, there are three places near the center and both ends of the holding frame or two places at both ends on the side surface. Then, the bands 6 are laid so as to be orthogonal to each other on a plane, and are tightened with a strong force to prevent collapse of the load. For this reason, the holding frame 5 must have compression resistance enough to withstand tightening, and have permanent distortion resistance that does not deform even when tightened for a long time.

As a known example of such a holding frame, there is a holding frame for pallets described in Japanese Utility Model Laid-Open No. 5-3131. The holding frame is composed of an annular rectangular main frame 6 forming a peripheral portion and a cross-shaped auxiliary frame 7 located inside the main frame 6.
Are provided in a state in which an auxiliary core material 8 using a steel pipe such as carbon steel for machine structure is embedded, and around the four corner-shaped spaces S formed by being surrounded by the frames 6 and 7, respectively. , A mesh-shaped portion 9 having a hole V penetrating vertically. Further, "the protrusions 10 are provided over the entire circumference at the center position in the vertical width direction on the lateral outer surface of the main frame 6, and auxiliary ribs 11 for the protrusions 10 are provided at appropriate intervals in the protrusion longitudinal direction. . "

[0005]

In the above known holding frame, the auxiliary core material 8 is embedded to prevent deformation due to band tightening, so that the main frame 6 is not pressed by tightening. Will not be crushed or destroyed. However, since the auxiliary core material 8 is a steel pipe,
The band portion is bent by the long-time tightening, and the entire side is deformed into a wavy shape. If it is deformed in a wavy manner, the auxiliary core material 8 is a steel pipe, so that not only does it not return to its original state but also makes it difficult to forcibly restore it even if the tightening is released. Then, the presser frame deformed in a wavy manner is not suitable for reuse. Also, since the auxiliary core 8 is insert-molded, it takes time and labor to attach the auxiliary core to the mold together with the material cost, and the cost of the product is increased as a whole. Furthermore, since the auxiliary core material, which is a steel pipe, is embedded, there is a problem that the entire weight increases and it is difficult to handle.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is not only lightweight and easy to handle, but also has compression resistance,

Since the band is orthogonal to the band to be tightened, the band has sufficient strength against the band tightening force. In addition, since drain holes are formed in each chamber surrounded by the ribs, rainwater and the like can be quickly discharged. Further, since the outer side surface and the upper surface of the outer peripheral rib are continuous with each other by the tapered surface, the familiarity of the band is improved, the tightening is easy, and the band is prevented from shifting. Reinforcement ribs connecting the corners are provided on the inside of the four corners of the peripheral frame and the connection part between the peripheral frame and the cross-shaped reinforcing plate to form an octagonal through hole, so the four corners and the connection part are reinforced and high rigidity as a whole It can be a holding frame.

Further, by reducing the interval between the orthogonal ribs provided between the outer peripheral rib and the inner peripheral rib at the center and the end of each side, the bending can be further prevented. Further, the small ribs connecting between the outer rib and the inner rib adjacent to the outer rib serve to improve the strength of the peripheral portion.

[0009]

Next, an embodiment of the present invention will be described in detail with reference to the drawings. 1 is an overall plan view, FIG. 2 is a bottom view of the entirety, FIG. 3 is a front view, FIG. 4 is an enlarged view at four corners of FIG. 1, and FIG. FIG. 6 is an enlarged sectional view of the peripheral frame, and FIG.
It is an enlarged view in a line sectional view. The holding frame 10 is formed by integrally connecting a cruciform reinforcing plate 13 inside an annular rectangular plate-like peripheral frame 11 constituting a peripheral portion.
Are connected at substantially the center of each side of the peripheral frame 11. A reinforcing rib 16 connecting the corners of the connecting portion of the reinforcing plate 13 and the reinforcing ribs 14 connecting the insides of the four corners and a reinforcing rib 18 of an intersection connecting the corners of the reinforcing plate 13 are provided to reinforce the connecting portion. In addition, four substantially octagonal through holes 15 are provided inside.

The peripheral frame 11 has an outer peripheral rib 17 and an inner peripheral rib 19 provided on one surface of an annular plate body 12.
A parallel inner rib 20 is provided between the inner rib 7 and the inner peripheral rib 19. The parallel inner ribs 20 are connected to the oblique ribs 21 which cross the outer peripheral ribs 17 at approximately 45 degrees at four corners. The outer peripheral rib 17, the inner peripheral rib 19, the inner rib 20, and the oblique rib 21 are formed at substantially the same height in the vertical direction. Since the outer rib 17, the inner rib 19, and the inner rib 20 are orthogonal to the band to be tightened, they are sufficiently reinforced for the pressing force to be tightened and prevent deformation due to bending.

Further, on one surface of the peripheral frame 11, there are provided orthogonal ribs 23 orthogonal to the outer peripheral ribs 17, the inner peripheral ribs 19 and the inner ribs 20. The orthogonal ribs 23 are provided with a narrow interval at a center portion and an end portion of the peripheral frame 11 where the peripheral frame 11 is hooked. That is, in the range of the connecting portion B between the adjacent portion A of the four corners and the reinforcing portion 13, the interval is provided to be narrow. Thus, the strength against the tightening force is further improved by reducing the interval between the orthogonal ribs 23. A small hole 27 for draining water is formed in each of the chambers 25 which are surrounded by the ribs and have an open top surface. The size of the drainage hole can be determined as appropriate, and if drainage is possible, the smaller the strength, the better. As is clear from the above description, the peripheral frame 11 is provided with ribs vertically and horizontally on the upper surface of the plate body to form the chamber 25 opened on the upper surface, and the chamber in the banding portion is formed small, so that the peripheral frame 11 has high rigidity. There is no deformation due to the tightening force.

As shown in FIGS. 5 and 6, the corners between the outer surface 29 of the outer peripheral rib 17 and the upper surface 30 and the lower surface 31 are tapered surfaces 33 and 35. In particular, since the upper surface 30 and the outer surface 29 that are in contact with the band are made continuous by the tapered surface 33, the familiarity of the band is improved.
It is easy to tighten, and retains the tightening force to prevent the band from shifting. The tapered surfaces 33 and 35 include not only a completely straight surface but also a slightly curved surface.

Small ribs 56 are provided between the orthogonal ribs 23 to connect the outer ribs 17 and the inner ribs 20 adjacent to the outer ribs 17. Each of the small chambers having an open upper surface surrounded by the orthogonal ribs 23, the outer peripheral ribs 17, the inner ribs 20, and the small ribs 56 is provided with small holes for draining vertically therethrough. By providing the small rib 56, the strength of the peripheral portion can be further improved. Note that a plurality of small ribs 56 may be provided between each of the orthogonal ribs 23, and the small ribs 56 are not necessarily required to be parallel to the orthogonal ribs 23.

A part of the outer surface 29 of the outer peripheral rib 17 is provided with a recess 36 which is slightly cut out. The concave portion 36 is provided between the banded portions A and B, and one concave portion 36 is provided on at least two outer surfaces 29 facing each other. By coating the concave portion 36 with an appropriate color, the concave portion 36 can be used as a mark indicating the owner, or as a mark of the number of stages in the case of stacking in multiple stages. By being recessed from the outer side surface 29 and being provided at a position deviated from the band hanging portion, it is possible to prevent rubbing.

Next, the cross reinforcing plate 13 will be described. Similar to the peripheral frame 11, the cross-shaped reinforcing plate 13 has an edge rib 37 on the upper surface of the cross-shaped plate body 38 and the edge rib 37.
Inner rib 39 parallel to the end rib 37 and the inner rib 3
Each of the chambers 41 has orthogonal ribs 40 orthogonal to 9 and is surrounded by the ribs and has an open upper surface. And the peripheral frame 1
Reinforcing ribs 16 are provided at the corners of the connecting portion with the reinforcing member 1, and reinforcing ribs 18 are provided at the corners of the intersections at the center to reinforce each. As described above, the strength of the connecting portion can be increased by the reinforcing ribs 16 and the reinforcing ribs 18 together with the reinforcing ribs 14 inside the four corners. The reinforcing ribs 16 and the reinforcing ribs 18 are desirably provided on the upper surface of a triangular plate body 45 which is flush with the plate bodies 12 and 36, and a small hole 47 for draining water is desirably formed.

Further, the positioning structure of the four corners when the holding frames 10 are stacked will be described with reference to FIGS. 1, 2 and 7. FIG. At the four corners of the inner peripheral rib 19 of the peripheral frame 11,

0, the upper surface of the triangular plate 50, that is, the inner circumferential rib 1
A fitting rib 51, which is slightly higher than the height of the inner peripheral rib 19, protrudes from the 9 side. The fitting rib 51 is inclined with respect to the inner circumferential rib 19 similarly to the oblique rib 21,
In the embodiment, a plurality of projections are provided at an appropriate interval of approximately 45 degrees. In the embodiment, five fitting ribs are formed.
And since it protrudes in the range of the triangular plate body 50, the central part is long and it is formed short gradually toward both sides. A small hole 53 for drainage is provided between each fitting rib 51.
Are drilled.

On the opposite surface corresponding to the fitting rib 51, a fitting groove 55 is provided as is clear from FIGS. The fitting groove 55 is larger than the fitting rib 51 and is formed in a large number. That is, if the width of the fitting groove and the thickness of the connection rib 51 and _{T 1} and _{T 2} is _T 1 _{<T 2, 4~6mm} the _{T 1,} the _{T 2} and 8 to 12 mm, preferably _{T 2} Is about twice T ₁ . The length of the fitting groove 55 is longer than the length of the fitting rib 51 and is 1.1 to 1.3 times as long. That is, as shown by a dashed line in FIG. 2, the fitting groove 55 is formed so as to protrude from the triangular plate body 50 and reach the plate body 12, and the end face is open on the side of the reinforcing ribs 14 and is formed with water. The small holes 53 communicate with each other. The protruding height of the fitting rib 51 and the depth dimension of the fitting groove 55 are substantially the same, each being 0.5
To 1.5 mm, preferably 0.8 to 1.2 mm.

In the case where the positioning structure according to the above configuration is provided, when the holding frames are stacked, the upper fitting ribs 51 are fitted into the lower fitting grooves 55 and positioned, so that the stacking can be performed neatly. At the same time, they can be stacked safely without slipping off easily. In addition, there is an initial movement in the fitting groove 55 between the fitting rib 51 and the fitting groove 55 by the amount of the clearance, and the engaging force acts in an oblique direction. Can be taken out. The fitting rib 51 and the fitting groove 55
Is formed at approximately 45 degrees with respect to the inner circumferential rib 19,
A shift in any direction can be prevented.

[0019]

As is clear from the above, according to the present invention, the following specific effects can be obtained. That is, since the ribs running vertically and horizontally are provided on one side of the plate, a lightweight and robust holding frame can be obtained. Further, since a drain hole is formed in a chamber surrounded by each rib, rainwater or the like is immediately discharged to prevent dirt. In addition, since the outer side surface and the upper surface of the outer peripheral rib are continuous by the tapered surface, the adaptation of the band to be tightened can be improved, and the band can be prevented from being displaced in combination with the fact that the tightening force can be increased. In addition, by forming the inside with an octagonal through-hole, the four corners and the connecting portion are reinforced, so that a highly rigid holding frame as a whole can be obtained. The strength can be improved by reducing the interval between the orthogonal ribs at the center and the end of each side where the band abuts. In addition, by providing a concave portion on the side surface, it is possible to prevent the mark from being rubbed, for example, by painting. Further, by providing small ribs between the orthogonal ribs for connecting between the outer peripheral rib and the inner rib adjacent to the outer peripheral rib, the strength of the peripheral edge portion is further improved.
