Description

  The present invention relates to a wagon suitably used in an office or the like.

  2. Description of the Related Art Conventionally, in offices, various wagons have been proposed for placing and taking out materials and the like by placing them in a lower limb space of a desk or adjacent to a desk. Some of them have been designed to allow users to unload materials quickly and accurately, such as those that have drawers that are opened sideways as well as above so that users can easily see the materials when they are pulled out. It is disclosed (for example, see Patent Document 1).

  By the way, in order for a user working at the desk to access the wagon from the posture seated on the chair and take out the material, the posture is raised, and if necessary, the chair is moved backward if necessary. However, it is common to perform a series of operations such as drawing the drawer and taking out the material after that. In this case, in a wagon in which other materials are also stored or placed on the upper surface of the wagon, the amount of movement that the user moves to the rear inevitably increases. Of course, after the material is taken out, the drawer must be closed, the chair must be moved forward to the position where it was working, and the upper body must be returned to the working position described above.

  In other words, as described above, when using a conventional wagon, the user must go through many procedures regardless of whether or not he / she is conscious of putting in / out materials. Repeatedly, a certain amount of work time has been spent so far.

Japanese Patent No. 40346686

  The present invention focuses on the above-described points, and an object of the present invention is to provide a wagon that contributes to more effective use of office hours by quickly putting in and out materials and the like.
