Embodiment 1 FIG.
The first embodiment shown in FIGS. 1 to 5 is attached to the tubular body 2 when the tubular body 2 having the protruding structure 1 on a part of the outer periphery is housed and packaged in the cardboard box 3 as shown in FIG. Thus, the present invention relates to a cushioning member for tubular body packaging that protects the tubular body 2 by buffering. Examples of the tubular body 2 include a fireproof damper device in which a damper is incorporated in a straight tubular air passage as shown in FIGS. 1 and 2 and a drive portion of the damper is provided on the outer periphery of the air passage. In addition, the present invention can also be applied to an article in which a motor, a lever, a handle, and the like protrude as the protruding structure 1 on the outer periphery of the circular tubular body. The tubular body 2 according to the first embodiment is provided with attachment brackets 7 having side portions 5 on both sides of the web portion 4 and flanges 6 bent outwardly at the ends of the side portions 5 as accessory parts. It has been.
[0013]
The buffer member is composed of a pair of support legs 8 made of corrugated paper and a buffer material 9 made of corrugated paper. Each support leg 8 has the same shape and dimensions, and a corrugated cardboard sheet 10 punched into a developed shape as shown in FIG. 4 is assembled into a gate shape as shown in FIG. 3 by bending two bent ruled lines 11 at substantially right angles. It is done. The corrugated cardboard sheet 10 has a rectangular shape, and one support surface 12 having the same size is defined near each short side, and an upper surface 13 is defined in the center between the support surfaces 12. On one support surface 12, a round hole 14 having a diameter substantially equal to the outer diameter of the tubular body 2 is formed at the center in the width direction. An accessory storage part 15 is formed in a concave shape in the center of the upper surface 13, and two slit portions 16 are formed so as to protrude into the support surface 12 with the round hole 14. The distance between the edge of the round hole 14 of the support surface 12 and the edge of the upper surface 13 is set to be approximately equal to the protruding amount of the protruding structure 1 of the tubular body 2. The length of the short side of the corrugated cardboard sheet 10 is substantially equal to the length between the ends of the flange 6 of the mounting bracket 7, and the dimension in the short side direction of the accessory storage unit 15 is the side of the mounting bracket 7. It is slightly larger than the dimension between 5.
[0014]
The cushioning material 9 has a long side slightly shorter than the dimension in the center line direction of the tubular body 2, and the short side has a length that is approximately the length of the slit part 16 plus the dimension between the slit parts 16. A rectangular corrugated cardboard sheet 17 as shown in FIG. 2 is assembled into a channel shape as shown in FIG. 2 by bending the two bent ruled lines 11 at substantially right angles.
[0015]
At the time of packaging, the tubular body 2 is fitted with a support leg 8 assembled in a gate shape with the upper surface up using round holes 14 at both ends, and the tubular body 2 is supported so that the protruding structure 1 is on top. It is held horizontally between the legs 8 (see FIG. 2). The mounting bracket 7 is housed in one accessory housing portion 15 so as to be held on the upper surface 13 by the flange 6, and the cushioning material 9 is inserted into the slit portions 16 of the respective support legs 8 on both side surfaces to cover the protruding structure 1. It is mounted horizontally between the support legs 8 so that it crowns. One end of the cushioning material 9 comes into contact with the support surface 12 on the outer side of the support leg 8 on which the mounting bracket 7 is not mounted, and the accessory storage unit 15 is closed on the upper surface 18 of the cushioning material 9. Since the cushioning material 9 is short, it is not closed and the mounting bracket 7 is visible from the outside. The assembly as a whole is placed in close contact with the cardboard box 3 and sealed to complete the packaging. The protruding structure 1 of the tubular body 2 is held on the side surface 19 of the cushioning material 9, thereby restricting the rotation of the tubular body 2.
[0016]
Each support leg 8 of this cushioning member is a portal type, and the lower part is not joined. However, since the end surface of the tubular body 2 is in contact with the outer support surface 12 without the round hole 14, In addition, the stability of the shape is high both in the front-rear direction load and in the side direction load, and a sufficient buffer protection function is achieved. The load applied to the cardboard box 3 from the front-rear direction is primarily borne by the support surface 12 and the end surface of the upper surface 13 of each support leg 8, but the mounting bracket 7 stored in the accessory storage unit 15 for large loads. The corrugated cardboard box 3 is prevented from being crushed by the support function of the receiving and mounting bracket 7, and the stored tubular body 2 is buffer protected.
[0017]
Thus, neither the support leg 8 nor the buffer material 9 has a simple structure with a stepped portion or an adhesive bonding part, and has a simple packaging material. Thus, improvement in manufacturability, discardability, and recyclability can be promoted. Since the support leg 8 is symmetrical, it can be manufactured with the same punching die, and the support leg 8 and the cushioning material 9 can be stored in a flat plate state, so that the storage efficiency is good. Since the mounting bracket 7 that is an accessory is easily visible directly from the outside, it is easy to check whether the mounting bracket 7 has been forgotten when packaging, and the mounting bracket 7 is not discarded when unpacked.
