Description

  The present invention relates to a knurled skirt, and more particularly to a knurled skirt that can change its direction on the spot while restricting movement.

As a nurse skirt used by a nurse or the like in a medical facility such as a hospital, for example, a patent document 1 is known.
In this skirt, a vertically long rectangular parallelepiped space is vertically divided into a plurality of spaces, a top plate is provided at the top, and a plurality of trays are provided below the top plate.
In addition, casters are provided at the four corners of the lower end of the skirt to enable the skirt to move in the horizontal direction.

  By the way, the conventional nur skirt as described above is generally provided with stoppers on casters at the lower corners of the nur skirt. By stopping the rotation of the caster by this stopper, the movement of the nurse skirt is restricted.

In conducting the recent years of medical practice, there is if you want to place the electronic device such as a personal computer or a tablet computer on the top plate of the nurse cart. In this case, it is convenient if the orientation of the nurse skirt can be changed on the spot to show the screen of the electronic device.
Similarly, when working in a narrow place, it has been required to change the direction of the nurse skirt on the spot.

  However, the conventional knurled skirt is only provided with casters for movement, and there is a problem that it is difficult to change only the direction in which a heavy object is placed. Also, in the situation where the caster stopper is used so that the knurled skirt does not move, the direction of the knurled skirt cannot be changed if two or more casters are stopped. There was a problem that the nurse skirt moved greatly with the fulcrum as the fulcrum.

The upper end of the opening of the tray 4 has a shape that is folded back toward the outside of the tray 4, and the tray 4 is placed on the nurse skirt 1 by placing the folded portion on the upper end of the slide rail. The The tray 4 can slide in the front-rear direction of the skirt 1 by sliding on the slide rail.
Further, since the slide rail is covered by the folded portion of the tray 4, the slide rail is not conspicuous and the aesthetic appearance is not impaired.

As shown in FIGS. 1 and 4, the base frame 5 includes a horizontal frame portion 5a extending in the horizontal direction so as to connect the lower ends of the left and right support columns 3, and a vertical frame 5b extending from the left and right ends of the horizontal frame portion 5a to the front and rear. And is formed in a substantially H shape in a plan view.
The base frame 5 has the above-mentioned shape by combining a plurality of bent metal plates. Arbitrary materials can be used for the material, thickness, processing method, etc. of the metal plate, and it may be integrally formed by casting or the like without combining plate-like members. Any material other than metal may be used as long as it can support the weight.

As shown in FIG. 3, the vertical frame portion 5 b is provided with a gentle inclination so as to descend from the center toward the front and rear ends with the connection position with the horizontal frame 5 a, that is, the vicinity of the lower end of the support column 3 as the top. . Thereby, the vertical frame portion 5b is a member having a substantially arch shape upward in a side view.
By making the vertical frame portion 5b have an upward substantially arch shape with the vicinity of the lower end of the column 3 at the top, it is possible to receive the load of the skirt 1 and the load and to prevent the vertical frame portion 5b from being bent.
As will be described later, in this embodiment, the stopper 9 is provided on the base frame 5 and the protruding amount when the stopper 9 is lowered is 0.5 to 1 mm. However, if the base frame 5 is easily bent, the protruding amount is large. It will change. In the present embodiment, the vertical frame portion 5b is formed in a substantially arch shape, so that bending can be prevented, and changes in the protruding amount of the stopper 9 due to the weight of the knurled skirt 1 and the load can be prevented.
Furthermore, a space for placing a stopper 9 described later can be provided between the horizontal frame portion 5a located on the top of the arch and the floor surface. Further, since the vertical frame portion 5b is inclined before and after the lower side of the nurse skirt 1, the vertical frame 5b can be used in place of the footrest when sitting on a separately prepared chair or the like. Thereby, a comfortable working environment can be provided to the user.

As shown in FIGS. 1 to 3, casters 8 for moving the nurse skirt 1 are provided on the lower surface of the vertical frame 5 b at the front and rear ends, respectively.

As shown in FIGS. 2 to 4, a bottom surface (lower surface) of the horizontal frame 5a is formed with a stopper fixing base 5c having a central portion protruding downward in a substantially quadrangular prism shape. The stopper fixing base 5c functions as a pedestal for fixing a stopper 9 described later, and installs the stopper 9 at a predetermined height.
In this embodiment, the stopper 9 is directly fixed to the stopper fixing base 5c. However, a bracket, a spacer or the like may be provided between the stopper 9 and the stopper fixing base 5c in accordance with the overall length of the stopper 9 or the shape of the upper end. good. In the case of such a configuration, stoppers 9 having various shapes can be used for the nurse skirt 1. Even when the base frame 5 is bent due to deterioration over time and the clearance between the stopper 9 and the floor surface is changed, the clearance can be adjusted by exchanging brackets and spacers.
Further, the stopper fixing base 5c may be formed as a separate member without being integrally formed with the base frame 5. In this case, the function of the bracket can be exhibited by the stopper fixing base 5c itself.

A stopper 9 is attached to the lower surface of the horizontal frame 5a of the base frame 5 as shown in FIGS.
As shown in FIGS. 5A and 5B, this stopper mainly includes a stopper main body 9a, a piston 9b, a stopper abutting portion 9c, and elevating pedals 9e and 9f.

The stopper main body 9a is a member for accommodating the piston 9b so as to be movable up and down and for installing the stopper 9 on the stopper fixing base 5c. The stopper main body 9a is entirely made of nylon resin. A cylinder (not shown) for accommodating the piston 9b is provided on the lower end side, and the upper end side is formed in a plate-like portion having a substantially rectangular shape in plan view. ing.
In the plate-like portion at the upper end of the stopper main body 9a, holes with a diameter of about 8.5 mm are provided in the vertical direction at intervals of 80 mm in the front, rear, left and right sides. The stopper fixing base 5c is also provided with a bolt hole at a position corresponding to this, and the stopper 9 is installed in the base frame 5 by inserting a bolt into the hole and screwing it into the stopper fixing base 5c.

A piston 9b is attached to the stopper body 9a so as to be movable up and down, and a stopper abutting portion 9c for abutting against the floor surface is provided at the lower end of the piston 9b to prevent the movement of the skirt 1. Yes.
The stopper contact portion 9c is a substantially disk-shaped member having a diameter of about 66 mm, and a rubber cushioning material 9d is provided at the lower end.

Further, on the upper side of the stopper path body portion 9a, side view L-shaped downward pedal 9e in order to lower the piston 9b are rotatably supported, increasing the piston on the upper end side of the piston For this purpose, a lift pedal 9f that is substantially L-shaped in side view is rotatably supported. Further, the elevating pedals 9e and 9f are connected to each other by a connecting pin at an intermediate portion so as to be rotatable.
As shown in FIG. 5A, when the stopper is raised, the lowering pedal 9e is positioned above the raising pedal 9f. Here, when the lowering pedal 9e is depressed, as shown in FIG. 5B, the piston 9b is lowered and the raising pedal 9f is raised. Thereby, the piston 9b, the stopper contact portion 9c, and the cushioning material 9d can be moved up and down by operating the lifting pedals 9e and 9f.

The stopper 9 has an up / down stroke set to 25 mm, and the total length can be changed from 148 mm when ascending to 173 mm when descending.
In a state where the stopper 9 is installed on the skirt 1, the lowermost end of the stopper 9, that is, the cushioning material 9d of the stopper abutting portion 9c is positioned at a distance of 24 to 24.5 mm from the floor surface when the stopper 9 is raised. When the stopper 9 is lowered, it protrudes 0.5 to 1 mm downward from the floor surface. If the amount of protrusion of the cushioning material 9d of the stopper abutting portion 9c is too small, the stopper abutting portion 9c and the cushioning material 9d cannot be sufficiently pressed against the floor surface, and if too large, the skirt 1 is lifted and the posture becomes unstable. Therefore, about 0.5 mm to 1 mm is desirable. However, when a stopper provided with an elastic member such as a spring is used for the piston 9b, the protruding amount may be 1 mm or more.
When the stopper 9 is lowered, the buffer material 9d of the stopper contact portion 9c is pressed against the floor surface, and the movement of the skirt 1 in the horizontal direction is restricted by the friction between the buffer material 9d and the floor surface.
Not any wheel casters 8 is restricted rotation in this state, around the stopper 9 can be changed only orientation of the nurse cart 1. At this time, the buffer material 9d of the stopper abutting portion 9c slides on the floor surface. However, by setting the amount of protrusion of the stopper 9 to 0.5 mm to 1 mm, excessive resistance against the change of direction is obtained. It will not be.
Since the stopper 9 is located at the center of the horizontal frame 5a of the base frame 5, it is located near the center in the bottom view of the skirt 1, and the direction of the skirt 1 is easy even when there are obstacles on the front, rear, left and right. Can be changed to
Further, by providing the cushioning material 9d on the lower surface of the stopper abutting portion 9c, it is possible to suppress noise during contact with the floor surface and to exert a frictional force necessary for restricting the movement of the knurled skirt 1. .

Further, on the back side of the top plate 2 of the skirt 1, a handle 6 having a grip at a position substantially the same as the top plate 2 is provided.
The handle 6 can be used as an armrest when a personal computer or the like is placed on the top board 2, but the direction of the armrest can be easily adjusted by changing the direction of the nurse skirt 1. When a single personal computer or the like is used by a plurality of persons, the orientation of the personal computer or the armrest can be adjusted simultaneously by changing the orientation of the nurse skirt 1 each time the person in charge of the operation changes. .

The specific configuration of the present embodiment is as described above, but the configuration of the present invention is not limited to the above embodiment.
For example, in this embodiment, the protruding amount of the stopper 9 is defined by the height of the stopper fixing base 5c, but as described above, it can be adjusted between the stopper 9 and the stopper fixing base 5c via a bracket, a spacer, or the like. It may be.
Moreover, in order to change the direction of the skirt 1 more easily, the stopper contact portion 9c and the cushioning material 9d may be rotatable with respect to the stopper main body portion.
Moreover, the top plate 2 may be made of metal or resin instead of wood.
Other specific configurations are not limited to the embodiment described above, and various modifications can be made without departing from the spirit of the present invention.
