Description

  The present invention relates to a rack in which a door is attached to a box so that the door can be opened and closed, and a method of using the rack that facilitates access to the upper portion of the rack.

  A rack that houses a plurality of devices such as a server unit and a network unit generally has a structure in which a door is attached to a box (housing) so as to be freely opened and closed. In such a rack, equipment may be stored at a high position that is out of the reach of workers. When repairing, exchanging, adjusting, or mounting the equipment on the upper part of the rack at such a high position, an operator has accessed the upper part of the rack on a work table such as a stepladder or a ladder.

Japanese Utility Model Publication No. 3-2681

  The following analysis is given by the inventor.

  If you work with a contractor during the work period such as on-site adjustment, the contractor may have a platform such as a stepladder or ladder, and borrow a platform such as a stepladder or ladder on the spot. Although it was possible to carry out the work, it was not always working with the contractor, and the contractor sometimes did not have a platform such as a stepladder or ladder. Therefore, the operator has to prepare and bring a stepladder or the like in advance.

  In many cases, a plurality of signal cables exist at the top of the rack. If there is no work platform such as a stepladder or ladder, or if a work platform such as a stepladder or ladder cannot be borrowed from a contractor, etc., or if there is no work platform such as a stepladder or ladder, or a substitute for it, the condition at the top of the rack However, it took more time than normal work to check the condition of the upper part of the rack, and the work efficiency was poor. Further, if the work on the upper part of the rack is performed in a state where the upper part of the rack is not clearly visible, the working posture is deteriorated, so that there is a possibility that the work is erroneously performed.

  In addition, when there is no work platform such as a stepladder or ladder, the unit cannot be repaired, exchanged, adjusted, or attached due to the lack of access to the equipment above the rack.

  In addition, if there is no work platform such as a stepladder or ladder, a substitute (for example, a chair) can be used instead, but it is made more suitable for the work than a work platform such as a stepladder or ladder. Not. For this reason, substitutes may lack stability, require careful caution not to use the original platform such as a stepladder, ladder, etc. to prevent toppling, and require more work and concentrate on the work. There was something I couldn't do. In addition, in order to ensure the stability of the substitute, an additional worker (one or more) may be required to hold down the substitute. Furthermore, there may be a problem that there is no substitute for the required height, and the number of substitutes is insufficient.

  In addition, when a network device is mounted on the rack, a communication cable is often laid on the front side of the rack. In such a case, when changing or replacing the cable laid on the upper side of the rack, not only the rear side but also the front side may require a work table such as a stepladder or ladder, or a substitute for it. there were.

  In many cases, a plurality of server racks and network racks are arranged in the machine room. When it is necessary to carry out the work on the upper part of the rack at the same time, since there is only one work table such as a stepladder and a ladder, the work is carried out in turn, resulting in poor work efficiency.

  In addition, depending on the work place, when bringing in a work platform such as a stepladder or ladder, it may be necessary to make an application.

  Furthermore, when a work platform such as a stepladder or ladder is prepared in advance in a rack or the like, or when a work platform such as a stepladder or ladder is incorporated in the rack (for example, see Patent Document 1 assuming that a ladder is detachably provided in a housing) ), There is a problem that the cost of the work table such as a stepladder and a ladder is added as it is, resulting in an expensive rack.

  The main subject of this invention is providing the low-cost rack which can perform the work of rack upper part easily, without preparing work platforms, such as a stepladder and a ladder, and its usage method.

  In a first aspect of the present invention, the rack includes a box having an opening and a door that can be detachably attached to the opening of the box, and the door is attached to the box. And a structure that can be fixed by leaning diagonally, and a structure that can be deformed as a work table while leaning diagonally.

  In a second aspect of the present invention, in the method of using the rack, the step of removing the door from the rack having a door that can be detachably attached to the opening of the box, and the removed door with respect to the box And a step of fixing the door leaning diagonally as a work table.

  According to the present invention, when working on the front and back of the upper part of the rack, the work on the upper part of the rack can be easily performed without separately procuring or borrowing work tables such as stepladders and ladders or substitutes thereof. Can do. In addition, the cost is lower than when a work table such as a stepladder or ladder is assembled to the rack or prepared separately.
