  The article case E described above moves the main body F in the left-right direction by positioning the right straight handle frame portion 51 constituting the medical wagon W between the main body F and the horizontal frame engaging portion G. Is regulated. More specifically, the article case E can position the right straight handle frame portion 51 between the left frame portion f3 in the main body F and the other movement restricting portion g22 in the horizontal frame engagement portion G. Is set to

  Attachment of the article case E to the medical wagon W is performed as follows, for example.

  The user grasps the main body F of the article case E and passes it through the space surrounded by the right handle frame 5 from the outside, and then the horizontal frame engaging portion G from above with respect to the second connecting frame 9. Engage. The inclined frame engaging portion H is engaged with the right straight handle frame portion 51 from the outside substantially simultaneously with the operation of engaging the horizontal frame engaging portion G with the second connecting frame 9.

  In the attachment state where the article case E is attached to the medical wagon W through the above attachment operation, even when the article case E receives a force in the vertical direction, the left-right direction, and the front-rear direction, It is designed not to leave the medical wagon W.

  As described above, the attachment structure of the article case E in the present embodiment is an optional article case for the second connecting frame 9 as a horizontal frame and the straight handle frame part 51 as an inclined frame in the medical wagon W as furniture. E is supported. The article case E is engaged with the main body F having the article accommodation space sp and the second connecting frame 9 provided in the main body F, and the horizontal direction that can restrict the forward and downward movement of the main body F. A frame engaging portion G and an inclined frame engaging portion H that is provided on the main body F and engages with the linear handle frame portion 51 and can regulate the rearward movement of the main body F are provided. For this reason, it is possible to provide an attachment structure that can favorably support the article case E in relation to the linear handle frame portion 51 that is an inclined frame. That is, the horizontal frame engaging portion G is provided with a structure that can restrict at least forward and downward movement, and the inclined frame engaging portion H is provided with a structure that can restrict at least backward movement. The article container E can be suitably supported by the medical wagon W.

  The movement of the main body F in the left-right direction is restricted by positioning the straight handle frame portion 51 as an inclined frame between the main body F and the horizontal frame engaging portion G. For this reason, the linear handle frame part 51 which makes the inclined aspect can comprise the aspect pinched | interposed between the main body F and the horizontal frame engaging part G, and the attachment structure of the article case E excellent in the balance is provided. It has become possible.

  The article case E is formed in a bowl shape using a metal frame member. For this reason, various articles can be accommodated in an aspect that is easily reduced in weight.

  The horizontal frame engaging portion G includes a downward U-shaped portion surrounding the second connecting frame 9 in a side view. For this reason, the movement to the front and rear and the downward direction of the article case E can be suitably controlled.

  The inclined frame engaging portion H includes a U-shaped portion surrounding the straight handle frame portion 51 in a front view. For this reason, in cooperation with the horizontal frame engaging portion G, the movement of the article case E can be suitably restricted.

  The horizontal frame engaging part G and the inclined frame engaging part H are respectively provided on the inner side of the main body F, and the inclined frame engaging part H is more than the horizontal frame engaging part G in the front view. It is arranged below. For this reason, the inclination frame engaging part H is arrange | positioned in the position suitably corresponding to the linear handle frame part 51 arrange | positioned in the inclined aspect.

  One end of the second connecting frame 9 which is a horizontal frame is connected to the inner side of the straight handle frame part 51 which is an inclined frame, and the main body F is located outside the straight handle frame part 51. For this reason, since the main body F can be arrange | positioned on the outer side of the medical wagon W, it becomes easy to take in / out goods.

  The inclined frame engaging portion H is provided with a lower movement restricting member h2 that is engaged with the straight handle frame portion 51 and is a retaining member capable of restricting forward and upward movement of the main body F. For this reason, even when a user unexpectedly contacts the article case E from behind, the lifting of the item case E can be suitably suppressed.

  The present invention is not limited to the embodiment described in detail above.

  Furniture is not limited to medical wagons. That is, the furniture may be anything as long as the option can be supported by the horizontal frame and the inclined frame.

  Of course, the options are not limited to the case.

  In the above-described embodiment, the option is configured to be detachable on the right side in front view of the furniture. However, the option may be configured to be attached on the left side. For example, if the options shown in the above-described embodiments are made symmetrical in the front-rear direction, a configuration that can be attached to the left side can be realized. Or the structure which can be attached to the right side of furniture and the structure which can be attached to the left side may be integrally provided in one option.

  In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
