Abstract

PROBLEM TO BE SOLVED: To provide an insert member for shaft packing that can be changed into a compact form while being unused. SOLUTION: In an insert member for shaft packing made up by providing shaft supporting sleepers 2 and 13 at the upside of a base board 3, the sleeper 2 is made up of a pair of rise walls 15 each formed by combining an inner rise board 8 and an outer rise board 10, and both of the rise walls 15 are joined together with the inner rise boards 8 butted against each other at their tail ends so that the rise walls can be risen and fallen freely while attachment pieces 11 are provided at the edges on tail ends of the outer rise boards 10 and fixation is made with the attachment pieces 11 fixed to the base board 3. The insert member can be changed into a flat form by falling the sleepers 13 and the rise walls 15 of the sleepers 2 toward the outside, and thereby piling-up in a compact form can be made for storage.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insert for packing a shaft having a constant velocity joint or the like interposed therebetween.

[0002]

2. Description of the Related Art An example of a conventional insertion material of this type will be described with reference to FIGS. As shown in FIG. 8, the insert includes a base 50 made of cardboard, a middle pillow outer frame 51, and insertion pads 52 and 53.

The base 50 has end pillow outer frames 55 connected to both end edges of a substrate 54. The end pillow outer frames 55 have an end plate 56, a top plate 57 and an upright plate 58 arranged in order from the substrate 54 side. At the same time, the winding piece 59 and the sticking piece 6 are attached to the outer edge of the upright plate 58.
0 are continuously provided, and a plurality of cuts 61 are provided so as to straddle the top plate 57 and the upright plate 58.

[0004] A middle pillow outer frame 51 is provided with a pair of upright plates 6.
2 and 62 are continuously provided via a top plate 63, and a bottom plate 64 and a folding piece 65 are sequentially provided on the outer edge of one of the upright plates 62 so as to straddle both the upright plates 62, 62 and the top plate 63. The insertion pad 52 has a configuration in which a pair of upright plates 67, 67 are connected to each other, and the insertion pad 52 is provided with a notch 68 over both the upright plates 67, 67. ing.

In order to assemble the insert shown in FIGS. 9 and 10 from the above members, the end plate 5
6 is erected, and the top plate 57, the erected plate 58, and the winding piece 59 are rolled up, and the three insertion pads 52 and one insertion pad 53 are inserted into each of the cylindrical end pillow outer frames 55. . At this time, each insertion pad 52 is folded in two, and
The receiving grooves 69 are formed by overlapping the cuts 7 and 67 with the cuts 61 and 68. Further, the insertion pad 53 is formed along the inner surface of the end plate 56. Then, the end pillow outer frame 55 and the insertion pad 5
The pillows 70 are formed by bonding the substrates 2 and 53 together, and the bonding pieces 60 are bonded to the substrate 54.

In the inner pillow outer frame 51, a pair of upright plates 62, 62 are bent downward with respect to the top plate 63, and the bottom plate 64 is bent in the horizontal direction. The insertion pads 52 are inserted. At this time, each insertion pad 52 is folded in two, the upright plates 67, 67 are overlapped, and the cuts 66, 68 are aligned to form the receiving groove 71. Then, the middle pillow outer frame 51 and the insertion pad 52 are attached to each other, the folding piece 65 is attached to the upright plate 62 on the opposite side to form a pillow body 72, and the bottom plate 64 is attached to the substrate 54.

In the insert thus constructed, the end and the middle of the shaft are supported by receiving grooves 69 and 71, respectively.

[0008]

However, in the above insert material, each pillow has a structure in which a pad is inserted into a cylindrical outer frame and both base ends of the outer frame are fixed to a substrate. Therefore, there is a problem that the pillow body cannot be turned down and becomes bulky when stored when not needed.

Accordingly, an object of the present invention is to provide an insert for shaft packing that can be compactly deformed when unnecessary.

[0010]

In order to solve the above-mentioned problems, the present invention relates to an insert for packing a shaft provided with a pillow for receiving a shaft on a substrate. And the outer standing plate are connected in series to form a pair of rising walls, and the both standing walls are joined to the base plate of the inner standing plate so that they can be raised and lowered freely, and attached to the base edge of each outer standing plate. A piece is provided, and each mounting piece is fixed to the substrate.

The insert thus constructed can be deformed into a flat shape by turning the rising wall of the pillow outward, so that it can be compactly stacked and stored.

In addition, the undulating operation of the rising wall is automatically performed from the middle by the repulsive force against the distortion of the inner standing plate, so that the deformation and restoration can be performed quickly and easily.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 and FIG. 2 show the expanded state of the base 1 and the pillow body 2 which form the insert. FIG.
In the base 1, four upright plates 5 are sequentially connected to both end edges of the substrate 3 via end plates 4, a plurality of cuts 6 are provided in each of the upright plates 5, and a central portion of the substrate 3 is provided. It is configured to have a pair of insertion holes 7.

In FIG. 2, the pillow body 2 comprises a pair of standing plates 8, 8 which are provided with two tongue pieces 9 extending from the opposite edges thereof.
The outer standing plate 10 is continuously provided at the outer edge of each inner standing plate 8, and the mounting piece 11 is provided at the open end of each outer standing plate. 10 and a plurality of cuts 12
Is formed.

To assemble the insert from the above members,
As shown in FIGS. 3 to 5, in the base 1, the upright plates 5 are folded inward, and the end plate 4, the upright plate 5, and the adjacent upright plates 5 are attached to each other to form a pillow body 13. . At this time, the notches 6 of the upright plates 5 are aligned with each other,
Is formed.

Further, in the pillow 2, a pair of rising walls 15 are formed by folding both the inner standing plates 8 and 8 into a mountain and folding the inner standing plate 8 and the outer standing plate 10 into a valley. And
The mounting piece 11 is attached to the substrate 3. Here, each rising wall 15
The receiving groove 16 is formed by the corresponding cut 12.

The insert material assembled as described above is used in a state where the pillows 2 and 13 are upright as shown in FIGS. Then, as shown in FIG. 5, when packing the shaft 17, the joint portion 18 is located between the pillows 2 and 13, and the end portion and the intermediate portion of the shaft 17 are supported by the receiving grooves 14 and 16, respectively. . Next, the inserts on which the shafts 17 are set are stacked in multiple stages and stored in an outer box.

When unnecessary, as shown in FIG. 6, the pillow body 13 and the rising wall 15 of the pillow body 2 are turned outward.
When it is deformed into a flat shape in this way, it can be compactly stacked and stored.

The undulating operation of the rising wall 15 is shown in FIG.
In the transition process between the falling state shown in FIG. 7A and the standing state shown in FIG. 7C, the inner standing plate 8 is compressed and distorted as shown in FIG. Automatically from the middle. Here, when the rising wall 15 rises, the tongue piece 9 is inserted into the insertion hole 7 as shown in FIG. 4C, so that the rising wall 15 is prevented from wobbling.

[0020]

As described above, the insert according to the present invention is obtained by causing the rising wall of the pillow to fall outward.
Because it can be deformed into a flat shape, it can be compactly stacked and stored.

In addition, the undulating operation of the rising wall is automatically performed from the middle by the repulsive force against the distortion of the inner standing plate, so that the deformation and restoration can be performed quickly and easily.
