  When the coil 50 is loaded on the carrier 12, the band-shaped cushion 35 and the cushioning material 34 are pressed to predetermined positions by the weight of the coil 50. Further, since the weight of the coil 50 also acts on the side supporting and fixing unit 30 via the cushioning material 34, the side supporting and fixing unit 30 is also fixed at a predetermined position.

  As described above, according to the present invention, since the side supporting and fixing unit 30 is provided along both sides of the carrier 12, the coil 50 is provided on the coil 50 via the longitudinal cushioning member 34 in the left-right direction (the width direction of the track). An inward force can be applied. Therefore, the movement of the coil 50 in the left-right direction can be restricted. In addition, since the first supporting and fixing unit 20 is provided at the front portion of the loading platform 12, a rearward (longitudinal direction of the track) force can be applied to the coil 50. Therefore, the forward movement of the coil 50 can be restricted. The side support fixing unit 30 could also be referred to as a lateral stop.

  Since the first support fixing unit 20 and the side support fixing unit 30 are each formed of a steel material, they have sufficient rigidity.

  In the present embodiment, the first supporting and fixing unit 20 and the side supporting and fixing unit 30 are attached to the loading platform 12 by using the stanch holes 15 formed in advance on the loading platform 12 of the truck. For example, the platform of a general cargo truck can be changed to a platform for loading coils.

A cushioning material 59 such as wood is provided between the coil 50a and the second coil 50b. A buffer material 59 such as wood is provided between the second coil 50b and the last coil 50c.

  In the above embodiment, the coil is mounted on the carrier, but the present invention can be applied to a case where something other than the coil is mounted. In addition, the first support / fixing unit 20, the side support / fixing unit 30, and the second support / fixing unit 54 have been described as being made of steel materials. However, if each unit is sufficient to support and fix the load on the loading platform, each unit may be used. There is no limitation on the material. That is, there may be a case where a part or all of each unit may be made of a material other than steel (for example, reinforced plastic).

  Further, the second portion 32 and the cushioning member 34 of the side support fixing unit 30 have been described as separate components, but they may be integrated. If it is not difficult for an operator to transport the second portion 32 and the cushioning material 34 at the same time, both may be integrated. In this case, the cushioning member 34 is composed of a plurality of pieces, and each piece is integrated with each second portion 32.

  The form of engagement between the first portion 31 and the second portion 32 of the side supporting and fixing unit 30 is not limited to that shown in FIG. For example, if there is no problem in strength without the flange 32d, the flange 32d may be omitted. That is, the first portion 31 and the second portion 32 may be connected only by the engagement between the extension portion 31c of the first portion 31 and the engagement portion 32a of the second portion 32. Alternatively, if there is no problem in the connection strength between the first portion and the second portion even if there is no engagement between the extension portion 31c of the first portion 31 and the engagement portion 32a of the second portion 32, the extension portion 31c The engaging portion 32a may be omitted. That is, the first portion 31 and the second portion 32 may be connected only by the engagement between the main body 31a of the first portion 31 and the flange 32d of the second portion 32.

  If it is necessary to strengthen the engagement between the first portion 31 and the second portion 32, for example, a lid member may be provided on the engagement portion 32a of the second portion 32. After the extension portion 31c of the first portion 31 is engaged with the engagement portion 32a of the second portion 32, the lid member is closed, whereby the extension portion 31c of the first portion 31 is engaged with the second portion. Do not leave the joint 32a.

Alternatively, as shown in FIG. 9, the engaging portion of the second portion 32 may be a U-shaped groove 32a ', and the extending portion 31c' of the first portion 31 may be a cylindrical projection that engages therewith.

  In the illustrated embodiment, the stanchion hole 15 is formed in a rectangular cross section. However, the load supporting and fixing device of the present invention can be provided even if the stanchion hole 15 is circular, slit-shaped, or polygonal other than square. Alternatively, it is also possible to attach the first support / fixing unit 20, the side support / fixing unit 30, and the second support / fixing unit 54 using holes or depressions not called stanchion holes.

  In the above embodiment, the coil 50 is supported and fixed on the carrier by the first support and fixing unit 20 and the side support and fixing unit 30 (and the second support and fixing unit). If there is no problem in transferring the coil, the first support fixing unit 20 may be omitted. Alternatively, instead of the first support and fixing unit 20, a cushion member may be simply provided between the front part of the carrier and the coil. Similarly, if there is no problem in coil transfer even without the second supporting and fixing unit, the second supporting and fixing unit may be omitted. Alternatively, instead of the second support and fixing unit, a cushion member may be simply provided between the rear portion of the carrier and the coil.

  The size and shape of the side support fixing unit 30 are appropriately selected according to the size and shape of the load. Similarly, the size and shape of the first support and fixing unit 20 and the second support and fixing unit are appropriately selected according to the size and shape of the load.

  Further, depending on the shape of the load, it may be better to provide the side support fixing unit 30 only on one side of the carrier 12 (for example, only on the right side). That is, the location and number of the side support fixing units 30 are appropriately selected according to the size, weight, shape, and the like of the load. It may not be necessary to use some of the stanchions of the carrier 12.
