  Below, one Embodiment of the conveying method which concerns on this invention using the said raising / lowering apparatus 1 is described, referring FIGS. 5-8. FIG. 5 is a flowchart showing a transportation method according to an embodiment of the present invention. FIG. 6 is a partial cross-sectional schematic view of the lifting device 1 that has undergone the placement process and the first movement process. FIG. 7 is a partial cross-sectional schematic view of the lifting device 1 that has undergone the support process. FIG. 8 is a partial cross-sectional schematic view of the lifting device 1 that has undergone the second movement step.

  First, as shown in FIG. 5, the transport method according to the present invention includes a placing step S1, a first moving step S2, a supporting step S3, and a second moving step S4.

  As shown in FIG. 6, the lifting device 1 that has undergone the placing step S <b> 1 and the first moving step S <b> 2 has the housing case 9 placed on the placing portion 5 and the engaging portion 11 engaged with the engaged portion 17. Combined state.

  The placement step S <b> 1 is a step of placing the housing case 9 on the placement unit 5. When performing the mounting step S1, for example, the locking member 15 that is an attachment portion of the mounting unit 5 and the slider unit 3 is mounted in a state where the mounting unit 5 is bottomed on a truck bed or a stabilizer 7 or the like. The slider part 3 is lowered by the elevating mechanism part 4 until it is located at the lower end position of the long hole 14 (hereinafter referred to as “first position”). Even if the housing case 9 is placed on the placement portion 5 in a state where the locking member 15 is lowered relative to the placement portion 5 and is positioned at the first position, the engagement portion 11 remains engaged. The engagement portion 17 is not engaged.

Subsequently, the first moving step S <b> 2 is a step in which the slider portion 3 is raised by the elevating mechanism portion 4 to engage the engaging portion 11 and the engaged portion 17. In the first moving step S2, the slider portion is moved until the locking member 15 arranged at the first position by the placing step S1 is located at the upper end position of the elongated hole 14 (hereinafter referred to as “second position”). 3 is raised by the lifting mechanism 4. The engaging member 11 and the engaged portion 17 are brought into the engaged state by raising the locking member 15 relative to the placement portion 5 to be positioned at the second position, so that the housing case 9 Is in a substantially fixed state with respect to the slider portion 3 while being placed on the placement portion 5.
As described above, as shown in FIG. 6, the locking member 15 is located at the second position, which is the upper end position of the long hole 14, and the engaging portion 11 is inserted into the engaged portion 17.

  Since the elevating device 1 that has gone through the first moving step S2 is in a state where the housing case 9 is substantially fixed, further elevating operation using the elevating mechanism unit 4, elevating using the grip unit 8 and the wheels T The tilting operation and movement of the device 1 can be easily performed as compared with the case where the user carries the storage case 9 directly. In addition, mounting process S1 and 1st movement process S2 are processes which load the storage case 9 in the raising / lowering apparatus 1. FIG.

  As shown in FIG. 7, the lifting device 1 that has passed through the support step S <b> 3 is in a state in which the placement unit 5 is in contact with a loading platform L such as a truck.

  The supporting step S3 is a step of supporting the placement unit 5 from below after performing the first moving step S2. Specifically, by bringing a truck bed L or the like into contact with the lower surface portion of the placement portion 5, a load directed from below to above is applied to the placement portion 5, so that the placement portion 5 is moved from below. The support state. At this time, the weight of each of the placement unit 5, the storage case 9, and the object stored in the storage case 9 is supported from below.

  Next, as shown in FIG. 8, the lifting device 1 that has undergone the second movement step S <b> 4 is in a state in which the engagement between the engaging portion 11 and the engaged portion 17 is released.

  The second moving step S4 is a step of releasing the engagement state between the engaging portion 11 and the engaged portion 17 by lowering the slider portion 3 by the elevating mechanism portion 4. In the second moving step S4, the slider unit 3 is lowered by the elevating mechanism unit 4 until the locking member 15 arranged at the second position in the first moving step S2 is positioned at the first position. By lowering the locking member 15 relative to the placement portion 5 and positioning it at the first position, the engagement between the engagement portion 11 and the engaged portion 17 is released, The substantially fixed state to the slider portion 3 is released in a state where the housing case 9 is placed on the placement portion 5.

  In addition, since the raising / lowering device 1 is in the state in which the placement portion 5 is supported from below by the support step S3, when the slider portion 3 is further lowered from the state shown in FIG. The case 9 is supported by the loading platform L and does not move, and only the slider portion 3 is lowered relative to the placement portion 5. Thereby, the engagement state can be released.

As described above, as shown in FIG. 8, the locking member 15 is located at the first position which is the lower end position of the long hole 14, and the engaging portion 11 is removed from the engaged portion 17.
Since the storage case 9 is not fixed to the lifting device 1 by performing the second moving step S4, the storage case 9 is slid in a substantially horizontal direction on the loading platform L of the truck, for example. The loading operation of the object on the loading platform L is completed. In addition, support process S3 and 2nd movement process S4 are processes which lower the storage case 9 from the raising / lowering apparatus 1. FIG.

  As described above, in the transporting method according to the present invention, the user does not need to lift the storage case 9 that stores a heavy object and moves it up and down.

  The transportation method using the lifting / lowering device 1 can be used for harvesting and transporting crops, for example. In this case, the storage case 9 for storing the harvested product is first subjected to the placing step S1 and the first moving step S2 in an empty state. Here, when the user goes up on the stepladder and stores the harvest in a harvesting basket prepared in advance, the user descends from the stepladder when an arbitrary amount of harvested product is stored in the harvesting basket. A harvesting operation including an operation of transferring the harvested product to the storage case 9 is assumed.

  After the empty storage case 9 is substantially fixed to the lifting device 1, the lifting device 1 is moved to a crop harvesting region, for example, near a stepladder for performing a harvesting operation. Furthermore, the height of the slider part 3, the mounting part 5, and the storage case 9 is adjusted according to the height at which the crop transfer operation set for each user can be easily performed, so that the storage case can be at any height. 9 is held. As a result, it is less likely that the user takes an unnecessary waist bending posture when the user descends from the stepladder after the harvesting operation and transfers the harvested product from the harvesting basket full of harvested products to the storage case 9. It is preferable because it can contribute to the reduction and prevention of back pain.

By using a container or the like for storing agricultural products as the storage case 9, the storage case 9 has a so-called stackable structure. That is, when the storage case 9 that is placed on the mounting unit 5 and is in a substantially fixed state directly to the lifting device 1 is filled with crops or the like, the slider unit 3, the mounting unit 5, and the storage case are moved by the lifting mechanism unit 4. 9, the empty storage case 9 can be stacked on the first-stage storage case 9, and the transfer work of the harvest can be continued. The first-stage storage case 9 is lowered, and the second-stage storage case 9 is held in accordance with the height of the harvest transfer operation, thereby transferring the harvest to the first-stage storage case 9. Similar to the replacement work, useless waist bending posture when transferring the harvested product of the user is reduced.
Further, the third stage storage case 9 can be stacked on the second stage storage case 9 to continue the harvest transfer operation.
Note that the engaged portion 17 may be provided only in at least the first-stage storage case 9 as long as the storage cases 9 can be stacked together.

The transport method using the elevating device 1 can also be applied when unloading the storage case 9 that is a heavy object and stores an object from the loading platform L of the truck. That is, the lower surface portion of the placement portion 5 on which the housing case 9 is not yet placed is brought into contact with the loading platform L, and the slider portion 3 is lowered with respect to the placement portion 5, and the support step S3 and the second movement step S4. By performing the same operation as, preparation for performing the mounting step S1 is completed. Thereafter, the placing step S <b> 1 is completed by sliding the housing case 9 horizontally onto the placing portion 5 on the loading platform L.
Even in this unloading operation, the user need not lift the container case 9 when it is moved up and down and transported.

  In addition, although embodiment which has arrange | positioned the locking member 15 in the 1st position was shown in mounting process S1 mentioned above, in the mounting process in this invention, a locking member is located in positions other than a 1st position, for example, 2nd. It is good also as engaging also when a user mounts a storage case in a mounting part after arrange | positioning in this position. Thereby, not only the placing process but also the first moving process is completed.

  Further, when the second moving step S4 is performed, if there is friction (resistance) between the elongated hole 14 and the locking member 15, the locking member 15 does not descend to the first position due to the weight of the slider portion 3. Sometimes. In this case, it is also possible to complete the second moving step S4 by manually pressing down the lever portion 12 shown in FIG.

Since the sliding contact portion 19 of the engaging portion 11 and the left-right width of the engaged portion 17 are formed to be substantially the same and slidably contact the opposing surface 18 of the reinforcing wall portion 16, the housing case 9 is left and right with respect to the slider portion 3. The backlash in the direction can be prevented.
Furthermore, since the two long holes 14 that are long holes in the vertical direction are arranged in the vertical direction and the locking member 15 is inserted through each of the long holes 14, the mounting portion 5 rattles the slider portion 3 in the horizontal direction. Can be prevented.
Therefore, the lifting device 1 according to the present embodiment can stably hold the housing case 9.

(Modification)
The present invention can take various forms other than the above-described embodiments as long as the object of the invention is achieved.

For example, instead of the above-described embodiment in which two long holes 14 and two locking members 15 which are long holes are provided, one long hole and a vertically long locking member may be used. Even in this configuration, it is possible to prevent the mounting portion from rattling in the left-right direction with respect to the slider portion.
Furthermore, instead of the lifting mechanism unit 4 combining a wire and a winch mechanism, a lifting mechanism unit using a ball screw may be used.
The lifting mechanism unit replaces the winding and feeding form of the wire W by manual rotation of the handle unit H described above, and attaches a rotary drive device such as an electric drill to the mounting portion of the handle unit H to wind the wire W electrically. Further, feeding may be performed.
