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.

  Conventionally, the top plate is provided with a handle on one side of a substantially rectangular plate-like member. If there is a handle on only one side of the top plate, there is no problem when moving it forward, but it is inconvenient when moving it horizontally or rotating it. That is, the direction of access to the skirt is limited.

  In this regard, a nurse skirt in which a handle is installed all around the top plate has been proposed (for example, Patent Document 1). According to this technique, the handle can be grasped in any direction. A nurse skirt to which this technology is applied can be accessed and moved from any direction.

  However, the skirt may be used with other equipment such as a table. When a skirt is used with a table, the skirt is placed near the table or placed close together so that a portion of the top lies on the top of the table.

  When such a method of use is performed, if there is a handle on the entire circumference of the top plate of the nurse skirt, the handle may get in the way.

  Hereinafter, a skirt 1 according to an example of an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a skirt 1 of the present embodiment. As shown in FIG. 1, the nurse skirt 1 includes a base portion 13, a single column portion 11, a tray 12, and a top plate 10.

  The base portion 13 includes two parallel vertical members 13A and a horizontal member 13B that connects the vertical members 13A to each other. The vertical member 13A is a bar-shaped member extending in the horizontal direction and having a rectangular cross section. The vertical member 13A is longer than the horizontal member 13B. Here, the longitudinal direction of the vertical member 13A is referred to as the front-rear direction, and the direction perpendicular to the horizontal direction with respect to the front-rear direction is referred to as the left-right direction. Casters 15 are respectively installed at the longitudinal ends of the vertical member 13A.

  The horizontal member 13B is disposed closer to the rear side than the intermediate position in the direction in which the vertical member 13A extends. A support column 11 is provided upright at the center of the upper surface of the horizontal member 13B. Moreover, the stopper 14 is provided in the lower surface side of the position in which the support | pillar part 11 of the horizontal member 13B is provided.

  The stopper 14 includes a pedal, a vertically extending portion, and a rotating portion. When the pedal is stepped on, the vertically extending part extends so that the skirt 1 floats several centimeters toward the floor. A rotation part is installed in the lower end of an up-and-down extension part, and rotates in a horizontal direction. Therefore, when the top plate 10 is rotated in a state where the vertically extending portion is extended, the nurse skirt 1 rotates on the spot around the rotating portion.

  The tray 12 is attached to the support column 11 by a support plate 12A and a coupler 12B. The support plate 12 </ b> A includes a plate-like member that is slightly smaller than the bottom surface of the tray 12, and a first engagement claw portion that is installed at the rear end of the plate-like member. The coupler 12B includes a lower claw portion that extends downward and a second engagement claw portion that is disposed on the opposite side of the lower claw portion. The tray 12 has a semi-cylindrical concave portion on the support column side, and includes an upper claw portion extending upward in the concave portion. The tray 12 has a gripping claw for gripping the plate-like member on the bottom surface. The support column 11 has a plurality of engagement holes arranged in two rows on the front side and the rear side, respectively.

  The support plate 12 </ b> A is attached to the support column 11 by engaging the first engagement claw with the engagement hole of the support column 11. The tray 12 is attached to the column portion 11 via the support plate 12A by causing the holding claws of the support plate 12A to hold the plate-like member. Thereafter, the coupler 12B engages the second engagement claw with the engagement hole and inserts the lower claw portion into the upper claw portion, thereby locking the tray 12 to the support column portion 11 from above.

  The tray 12 can be extended to the front long because the column portion 11 is installed on the base portion 13 in accordance with the publication. Therefore, the size of the tray 12 becomes larger and more objects can be placed than the column portion 11 is installed at the center position in the front-rear direction of the vertical member 13A.

  The top plate 10 is installed at the upper end of the support column 11. The top plate 10 is supported by the support column 11 at a position closer to the rear side than the center position of the top plate 10. The top plate 10 is disposed above the tray 12. Therefore, the top plate 10 does not protrude outward from the end portion of the base portion 13 in the front-rear direction, and the appearance and usability are improved.

  FIG. 2 is a plan view of the top plate 10. As shown in FIG. 2, the top plate 10 has a substantially rectangular shape with rounded corners. The top plate 10 has a length W1 in the front-rear direction that is longer than a length W4 in the left-right direction.

  The top plate 10 includes a placement portion 10C for placing an article and a gripping portion 10H formed on the entire circumference of the horizontal end of the placement portion 10C.

As shown in FIGS. 3 to 5, the gripping part 10H is formed to be thicker than the thickness H2 in the vertical direction of the mounting part 10C over the entire circumference.

  As shown in FIG. 5, the thickness H3 in the vertical direction of the main gripping portion 10A is thicker than the thickness H1 in the vertical direction of the sub gripping portion 10B. The sub-gripping portion 10B is formed to protrude upward by a thickness H4 from the upper end surface of the placement portion 10C. The sub-gripping portion 10B is formed to protrude downward by a thickness H5 from the lower end surface of the placement portion 10C. The thickness H4 is thinner than the thickness H5. Accordingly, the auxiliary gripping portion 10B protrudes more downward.

  The sub-gripping portion 10B draws a smooth curve upward from the end in the left-right direction, falls downward from the end in the left-right direction at a position C2 having a length W6, and forms an arc C1 having a center above the placement portion 10C. And smoothly connected to the upper end surface of the mounting portion 10C.

  The sub-gripping portion 10B draws a smooth curve downward from the left and right ends, climbs upward from the left and right ends at a position C3 having a length W7, and forms a circular arc C4 having a center below the placement portion 10C. And smoothly connected to the lower end surface of the mounting portion 10C.

  The sub gripping portion 10B bends with a smaller radius of curvature at the position C2 than at the position C3. The length W6 is substantially equal to or slightly shorter than the length W7.

Are smoothly connected to the upper end surface of the mounting portion 10C via an arc C5 having a center at the center.

  The main gripping portion 10A draws a smooth curve downward from the front and rear end, climbs upward from the front and rear end at a position C7 having a length W8, and forms a circular arc C8 having a center below the placement portion 10C. And smoothly connected to the lower end surface of the mounting portion 10C.

  The main gripping portion 10A bends at a position C6 with a smaller radius of curvature than at the position C7. The radius of curvature of the arc C5 is larger than the radius of curvature of the arc C8. The length W2 is substantially equal to or slightly shorter than the length W8.

  When the main gripping portion 10A is formed as described above, when the operator grips the main gripping portion 10A from the front-rear direction, the thumb is easily caught by the arc C5, and the palm is in close contact with the front-rear end portions of the main gripping portion 10A. Fingers other than the thumb are easily caught on the arc C8.

  Even when the operator puts his hand on the main gripping portion 10A, the thumb is easily caught on the arc C8, the front and rear ends of the main gripping portion 10A are in close contact with the palm, and the fingers other than the thumb are caught on the arc C5. It becomes easy.

  Therefore, the above-mentioned shape of the main gripping portion 10A can be easily moved by holding the gripping portion 10H of the top plate 10 regardless of whether it is gripped from the top or the bottom when gripped by hand. It is a shape that can be. And the holding part 10H is provided over the perimeter of the horizontal direction edge part of the top plate 10. FIG. Therefore, according to the nurse skirt 1 of the present embodiment, it is possible to easily move without grasping the directionality by grasping the grasping portion 10H without providing a handle.

  In addition, when using a synthetic resin for the material, the top plate 10 can be integrally molded by, for example, blow molding, but the molding method may be a molding method other than blow molding.

  The top plate 10 may be made of wood or metal. Furthermore, the top plate 10 can also be formed of a material different from the mounting portion 10C for the grip portion 10H.

  As described above, the knurled skirt 1 of the present embodiment has the gripping portion 10H disposed on the entire periphery of the top plate 10 and does not have a handle.

  Therefore, it is possible to hold the grip anywhere on the entire periphery of the top plate 10, and the operator can move the skirt 1 without worrying about the directionality, and the handle is not disturbed. .

  Further, the auxiliary gripping portion 10B has a smaller diameter than the main gripping portion 10A. The sub-gripping portion 10B has a thickness that allows easy gripping, and the main gripping portion has a thickness that allows a finger to be easily caught. And the connection part of 10 A of main grip parts and the sub grip part 10B is connected smoothly.

  Therefore, when the corner connecting portion of the main gripping portion 10A and the sub gripping portion 10B is gripped, it is possible to grip the sub gripping portion 10B having a small diameter and easy gripping, and the finger of the gripped hand becomes the main gripping portion 10A having a large diameter. There is an effect that the operator can easily and firmly grasp and move the nurse skirt 1 by being caught.
