Description

  The present invention relates to a skirt.

  In the medical field such as a hospital, a nurse skirt has been used to carry various materials such as laptop computers, drugs, and instruments. The nurse skirt includes a base portion having casters, a column portion provided upright on the base portion, a tray supported by the column portion, and a top plate provided at an upper end portion of the column portion.

  Since it is necessary to frequently clean and disinfect the tray, it is desirable that the tray be removable.

  In this regard, a plurality of locking holes are provided in the column, a ring having a locking projection that engages with the locking hole is coupled to a ring that fits the outer periphery of the tray, and the bracket is fitted into the locking hole. There has been proposed a skirt which is locked so as to be stuck and a tray is fitted into a ring (for example, Patent Document 1).

  However, according to this technique, when a large vibration is applied, for example, when the knurled skirt is moved, the tray or the bracket itself may come off.

  On the other hand, the looseness prevention mechanism that is screwed to the tray and restricts the vibration of the bracket is inserted in accordance with the locking hole while the locking projection is in the locking hole, thereby suppressing the rattling of the bracket. Furthermore, a technique for preventing the tray from coming off by screwing the tray to the bracket has been proposed (for example, Patent Document 2).

  However, this time, it is necessary to close and loosen the screws one by one when attaching and detaching the tray, which is troublesome.
