Description

  The present invention relates to a cart that has a movable leg base and a top plate disposed above the leg base, and is preferably used mainly in a medical field.

  Conventionally, in a medical field such as a hospital, in order to suitably carry the equipment required by the user, it has a movable leg base and a top plate disposed above the leg base, Various carts called so-called ner skirts have been proposed that can accommodate various equipment in the space below the top board and can be equipped with equipment that contributes to the work of workers such as personal computers on the top board (for example, , See Patent Document 1).

  The thing of this patent document 1 is in the position covering the whole circumference in the area below the top plate surface and outside the top plate so that the handle does not interfere with the object placed on the top plate surface. A handle is provided. As a result, the user can grip the handle from any direction.

  However, if the knurled skirt can be easily routed from any direction in this way, when the knurled skirt is moved in various directions more than ever before, there is no place on the top plate ever. Will be moved to. For this reason, even when the user moves the nurser skirt so that the handle is normally operated, the object placed on the top plate is shaken in an unprecedented direction and protrudes unexpectedly from the top plate. In some cases, this causes a problem that the mounted object falls.

JP 2010-105540 A

  The present invention pays attention to such problems, and an object thereof is to provide a knurled skirt capable of achieving both a high degree of freedom in handling a cart by a handle and a stable placement of an object on a top plate. It is said.

  In order to achieve such an object, the present invention takes the following measures.

  In other words, the nurse skirt according to the present invention includes a movable leg base, a top plate disposed above the leg base, and a peripheral edge of the top plate that is spaced along the top plate and below the top surface of the top plate. And a substantially annular handle having a low-order portion disposed on the top and a high-order portion disposed above the top surface of the top plate.

  The handle may be anything that can be used from any direction of 360 degrees, and is not limited to one in which the constituent members are connected in a complete ring shape. Even if it is interrupted at one or a plurality of locations, it may be in any form that can be accessed from all the surrounding directions.

  If this is the case, the operator can easily move from either direction by providing a substantially annular handle, and the one placed on the top surface of the top plate by providing a high-order part. It is possible to effectively avoid the problem of falling as the skirt moves. That is, it is possible to provide a knurled skirt that can achieve both a high degree of freedom in handling by the handle and a stable placement of the placed object on the top plate.

  Further, in most cases, considering that the operator moves the nurser skirt while being positioned on the use end side of the top plate, the handle includes a low-order part positioned on the use end side of the top plate, It is preferable to set it as the aspect provided with the high-order part located in the counter-use end side of a top plate. Thereby, it can prevent effectively that the mounting object on a top plate falls to the side located far from an operator.

  In addition, when the user grips the high level part, it is conceivable that the object placed on the top plate approaches the high level part and the space for inserting a hand is limited. When the guard member for preventing the gripping operation on the high-order portion from being hindered by the article placed on the plate is provided, the restriction on the space can be effectively avoided.

  When placing electronic devices such as a personal computer on the top plate, it is conceivable to place a power cord or communication cord below the top plate. If the hook is provided, it is possible to effectively avoid hooking these cords outside the nurser skirt.

  In order to effectively avoid that the impact concentrates on places where loads are easily applied, such as where the top plate is attached, even if the skirt is frequently turned by the handle, the top plate is attached to the leg base. It is preferable that it is attached to the upper surface of the support structure rigidly connected to the upper end of the upright support column, and the handle is supported by the support structure.

  According to the present invention, it is possible to provide a knurled skirt that can achieve both a high degree of freedom in handling by a handle and a stable placement of a placement object on a top plate.
