In addition, the user of the cart sits on the chair 50 with the legs on both sides of the slide bar 54 to measure or record the patient's condition in a comfortable position. At this time, if you adjust the height of the chair according to the height and physique of the user using the height adjustment device of the chair can work in a more comfortable posture.

In addition, when the cart user completes the work in one place, grab the handle 58 of the chair 50, push the cart 100 to the chair storage unit 40, the chair 50 is easily stored in the cart 100 do.

In addition, the measuring equipment or notebook used on the table 62 is closed or organized and the table 62 is pushed to the table storage unit 60, the notebook and the table 62 is easily stored in the cart 100.

Hereinafter, with reference to FIGS. 4 to 7 will be described the operation and effects in connection with the second embodiment according to the present invention.

As shown in FIG. 7, when the chair upper plate 70 is used in the state in which the chair upper plate 70 is accommodated in the cart 100 chair storage unit (see 76 of FIG. 6), the support upper plate 75 may be grasped and pulled up. ) Will be withdrawn. At this time, as shown in FIG. 6, the chair bar plate 70 is pulled out of the storage unit 76 while the connecting bar 74 hinged by the hinge member 71 provided in the lower plate 20 is rotated. The pair of support legs 75, which are folded in the state where the connecting bar 74 is level with the ground, are rotated and folded.

Next, the chair upper plate 70 which is rotatably mounted by the hinge member 71 on the chair support rod 73 installed on the chair support plate 72 is laid horizontally with the ground. In this state, as described in the first embodiment, the cart user pulls out the table 62 from the table storing unit 60, places a measuring instrument or a laptop on the table 62, and sits on a chair to perform a necessary task. .

After the work is finished, the table 62 and the used measuring equipment are stored in the cart 100, and as shown in FIG. 6, the chair upper plate 70 is rotated so as to be perpendicular to the ground, and a pair of supports are supported. Leg 75 is also folded to the center of the chair support plate (72). In this state, when the chair support plate 72 is lifted upward, the chair upper plate 70 is accommodated in the chair storage unit 76 by rotating in the direction of the cart 100 by the hinge member 71 of the connecting bar 74. .

8 to 11, the operational effects will be described with reference to the third embodiment of the present invention.

Referring to FIG. 10, when the chair 80 needs to be used in the state in which the chair 80 is accommodated in the cart storage unit 86 of the cart 100, the chair 80 is pulled out to the front of the cart 100. At this time, the connecting plate 84 coupled by the hinge member 81 to the fixing portion 82 installed on the lower plate 20 is rotated downward to operate horizontally. At this time, while the connecting plate 84 of the first member and the second member coupled by the hinge member 81 is released in the folded state, the chair 80 fastened to the second member connecting plate 84 is expanded. It is withdrawn from the chair storage unit (86). The pair of support legs 85, which are folded in the state where the connecting plate 84 is completely horizontal to the ground, are rotated to the outside of the chair 80.

Next, in this state, as described in the first embodiment, the cart user sits on the chair 80 and performs the necessary work in a comfortable posture.

After the work is finished, the table 62 and the measuring equipment used, etc. are stored in the cart 100, and when the chair 80 is pushed toward the chair storage unit 86 in the state shown in FIG. Since the first member and the second member connecting plate 84 are pivoted upward, the connecting plate 84 is folded so that the chair 80 can be accommodated in the chair storing unit 86.

According to the present invention of the configuration described above, it is very convenient to maximize the space utilization and can easily reduce the working intensity of the cart user because there is no need to move the work chair separately with a chair configuration that can be pulled out of the cart when needed There is an advantage to this.

The present invention described above is not limited to the above-described embodiments and drawings, and various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have In particular, the medical cart has been described above, but the present invention may be applied to a cart used in various other fields.

As described above, since the multi-purpose cart according to the present invention has a built-in chair that can be pulled out, there is no need to move with a separate working chair, and the effect of maximizing space utilization can be achieved.

In addition, according to the present invention can work in a comfortable posture by placing the measuring equipment on the table while sitting in a chair can also reduce the working intensity of the cart user.
