The contact part 27 is interlocked with the operation of the regulation operation part 26. That is, when the regulation operation part 26 is pushed in, the contact part 27 descends and comes into contact with the ground. When the restricting operation part 26 is pushed again, the restricting operation part 26 projects upward, and the contact part 27 rises and separates from the ground. The movement restricting section 24 is provided with a damper (not shown), and functions properly even if the ground has some irregularities.

  Next, the lifting operation mechanism 13 will be described with reference to the drawings. FIG. 5 shows the lifting operation mechanism 13.

  As shown in FIGS. 3 to 5, the raising/lowering operation mechanism 13 includes a base portion 14 connected to the support portion 4 below the base portion 8 and extends upward from the base portion 14 through the base portion 8. The operation unit 15, the sensors 18 and 19 as detection units for detecting the operation by the operation unit 15, and the operation control unit 20 for controlling the operation of the base unit 14 are provided. The base portion 14 has a cylindrical shape and is coaxially aligned below the support leg portion 3. The base portion 14 is supported by the support portion 4 of the base portion 8 inside the cylinder via a swing shaft portion 22 as a shaft portion. That is, the base portion 14 is freely inclined via the swing shaft portion 22. An operation portion 15 and a detected piece 23 are formed on the outer surface of the base portion 14.

  The operation portion 15 has a connecting portion 16 that extends from the side surface of the base portion 14 and is bent at a substantially right angle to pass through the hole 12b of the base portion 8, and a pedal portion 17 that is connected to the upper end of the connecting portion 16. ing. The connecting portion 16 is arranged so as to pass near the support leg portion 3, and the pedal portion 17 is arranged near the upper surface of the base portion 8. The detected piece 23 has a plate shape and projects outward from the base portion 14 in a substantially horizontal state.

  Each of the sensors 18 and 19 is a contact switch, and is composed of a pair of an ascending detection sensor 18 and a descending detection sensor 19. The sensors 18 and 19 are arranged laterally of the base portion 14 and face each other in the upper and lower sides. The switch parts of the sensors 18 and 19 face each other. The operation control unit 20 is composed of a pair of coil springs 21a and 21b and a stopper (not shown), and is arranged adjacent to each sensor 18 and 19 in the vicinity thereof. The coil springs 21a and 21b are coaxially arranged in series. The detected piece 23 of the base portion 14 is arranged between each sensor 18, 19 and each coil spring 21a, 21b. In other words, the descending detection sensor 19 is arranged above the detected piece 23, the ascending detection sensor 18 is arranged below the detected piece 23, and the coil springs 21a, b are arranged on the upper and lower surfaces of the detected piece 23, respectively. Are in contact. The sensor may be, for example, a magnetic type or an infrared type.

  Next, the operation of the practitioner's chair 1 will be described based on the drawings. 6 to 8 show the operating state of the practitioner's chair 1. 6 shows a state in which the treatment chair 1 is not operating, FIG. 7 shows a state in which the treatment chair 1 is lowered, and FIG. 8 shows a state in which the treatment chair 1 is raised. ing.

  As shown in FIG. 6, when the operation unit 15 is not operated, the base 14 is substantially horizontal and the detected piece 23 is also substantially horizontal. Therefore, the switches of the sensors 18 and 19 are not pressed, and the coil springs 21a and 21b have natural lengths.

  As shown in FIG. 7, for example, when the operating portion 15 is pushed toward the support leg portion 3 by the heel of the practitioner or the like, the base portion 14 rotates the swing shaft portion 22 relative to the support portion 4. And tilts (counterclockwise in FIG. 7). At the same time, the detected piece 23 tilts upward against the elastic force of the coil spring 21a, the switch of the descending detection sensor 19 is pressed, and it is detected that the operating portion 15 (base portion 14) has tilted, and the support leg portion 3 Contract and the seat portion 2 descends. At this time, the detected piece 23 hits the stopper to prevent the base portion 14 from being excessively inclined. While the switch of the descending detection sensor 19 is continuously pressed, the seat portion 2 continues to descend to the lower limit. When the practitioner's foot moves away from the operation section 15, the detected piece 23 is pushed by the restoring force of the coil spring 21b, and the operation section 15 (base 14) returns to its original position (see FIG. 6).

  As shown in FIG. 8, for example, when the operating portion 15 is pushed downward by the practitioner's heel or the like, the base portion 14 tilts with respect to the support portion 4 about the swing shaft portion 22 (in FIG. 8). turn right.). At the same time, the detected piece 23 inclines downward against the elastic force of the coil spring 21b, the switch of the ascending detection sensor 18 is pressed, and it is detected that the operation portion 15 (base portion 14) inclines. And the seat portion 2 rises. At this time, the detected piece 23 hits the stopper to prevent the base portion 14 from being excessively inclined. While the switch of the ascending detection sensor 18 is continuously pressed, the seat portion 2 continues to ascend to the upper limit. When the practitioner's foot separates from the operating section 15, the detected piece 23 is pushed by the restoring force of the coil spring 21a, and the operating section 15 (base 14) returns to its original position (see FIG. 6).

  As described above, the practitioner's chair 1 is configured. Next, the effect of the practitioner's chair 1 will be described.

  As described above, the practitioner's chair 1 has the lifting/lowering operation mechanism 13, and the lifting/lowering operation mechanism 13 includes the base portion 14 connected to the support portion 4 below the base portion 8 and the base portion 14 to the base portion 8. It has an operating portion 15 extending upward through the hole 12b and sensors 18 and 19 as detecting portions for detecting an operation by the operating portion 15 (see FIG. 5). When the operation portion 15 is pushed in a direction approaching the support leg portion 3, the base portion 14 is tilted about the swing shaft portion 22, and the switch of the lowering detection sensor 19 is pushed by the detected piece 23 and the operation portion 15 (base portion) is pushed. It is detected that 14) has tilted, the support leg 3 contracts, and the seat 2 descends (see FIG. 7 ). That is, when the seat portion 2 is lowered, the practitioner pushes the operating portion 15 toward the support leg portion 3, so that the practitioner's foot does not rest on the pedal portion 17 of the operating portion 15. If so, the foot is not caught between the seat portion 2 and the operation portion 15. Therefore, it is possible to safely and appropriately operate the lifting.

  When the operating portion 15 is pushed downward, the base portion 14 tilts about the swing shaft portion 22 and the detected piece 23 tilts downward, and the detected piece 23 pushes the switch of the rising detection sensor 18. It is detected that the operation portion 15 (base portion 14) is tilted, the support leg portion 3 extends, and the seat portion 2 rises (see FIG. 8 ). That is, since the raising of the seat portion 2 is realized by pushing the operating portion 15 downward, the manner of operation differs between the upward movement and the downward movement. Therefore, it is possible to prevent the practitioner from mistakenly performing the raising/lowering operation, and to perform the raising/lowering operation safely and appropriately. Further, since the single operation unit 15 is provided, visual identification is not required as compared with the case where the operation unit is different for raising and lowering.

  Further, it has a pair of ascending detection sensor 18 and descending detection sensor 19, and the detected piece 23 of the base portion 14 is arranged between the sensors 18, 19. By tilting the base 14, either of the sensors 18 and 19 reacts. Therefore, the single operation unit 15 can realize different operation methods for ascending and descending.

  Further, the base portion 14 and a part of the connecting portion 16 are hidden by being arranged below the base portion 8. Therefore, the chemical solution, blood, and the like scattered during the treatment are shielded by the base portion 8, and the base portion 14 and the connecting portion 16 are less likely to be contaminated.

  The connecting portion 16 of the operating portion 15 of the practitioner's chair 1 is arranged passing through the vicinity of the support leg portion 3. That is, it is possible to prevent the practitioner's foot from accidentally hitting the operation portion 15 around the base portion 8. Therefore, it is possible to safely and appropriately operate the lifting.

  The front side portion of the practitioner's chair 1 extends along the outer contour of the base portion 8 extending from the support leg portion 3 side toward the front and the front end of the base front frame portion 10 to the left and right. Holes 12a and 12b are formed between the base edge frame portion 11 and the base edge frame portion 11. The holes 12a and 12b are formed on the left and right of the front frame portion 10 of the base, and have a size that occupies most of the projected area of the front side portion excluding the frame portions 10 and 11, and, for example, the practitioner can put the tip of the foot The size is such that the heel fits into the base edge frame portion 11. That is, since the holes 12a and 12b formed over a wide range between the frame portions 10 and 11 are formed, the foot can be placed on the base edge frame portion 11, and a stable posture that is easy to perform can be taken. You can Further, since the scattered chemical liquid, blood, etc. pass through the holes, it is hard to adhere to the base portion 8 and the base portion 8 is hard to be soiled. Further, since the weight corresponding to the holes 12a and 12b is removed from the base portion 8, the weight is reduced.

  Further, the shapes of the front side portion and the rear side portion are obviously different, and the practitioner can easily recognize the difference between the front side portion and the rear side portion. Further, by using the holes 12a and 12b as markers, the front side and the rear side of the base portion 8 can be distinguished from each other, and the front side having the holes 12a and 12b can be easily recognized. Therefore, the orientation can be easily identified, and the operation unit 15 and the movement restricting unit 24 can be comfortably operated.

In the practitioner's chair 1, the casters 9 and the movement restricting portion 24 are attached to the base portion 8, and the movement restricting portion 24 of the base portion 8 is located at a distance from the support leg portion 3 to the outer contour of the base portion 8. The distance X _{1 on the} front side, which is the side to which is attached, is formed to be shorter than the distance X ₂ on the rear side, which is the side opposite to the movement restricting portion 24 with respect to the support leg 3. That is, since the front side portion is shorter than the rear side portion with respect to the support leg portion 3, the practitioner can easily recognize that the front side portion is the front side. When the practitioner sits on the seat portion 2 with the front side facing the front of the operator, the movement restricting portion 24 is naturally arranged at the foot directly below the front.

  Further, since the front part is shorter than the rear part, it is difficult for the base part 8 to come into contact with surrounding devices even when the base part 8 approaches the chair or bed of the subject.

  Further, if the movement restricting portion 24 is present in the front part of the base front frame portion 10 in the base portion 8, the practitioner will be at the feet as compared with the case where the movement restricting portion 24 is arranged on the center side in the base portion 8. The movement restriction unit 24 can be easily searched and can be operated comfortably. If the axis of rotation generated by the movement restricting portion 24 coming into contact with the ground exists in the front portion of the base front frame portion 10, the degree of rotation to the left and right is large, and the center side of the base portion 8 is the axis. Compared to the case of, it is easier to control the orientation and unintentional rotation is suppressed.

  Further, since the movement restricting portion 24 is attached to the front portion of the base front frame portion 10 that is arranged in the center in the left-right direction that is orthogonal to the front-rear direction in the front side portion, the movement restricting portion 24 is left and right in the front side portion. It exists in the center and in the front. With this configuration, since the movement restricting portion 24 comes into contact with the ground just below the front of the practitioner, the practitioner rotates the practitioner's chair 1 to the left and right with the front of the practitioner as an axis to perform the treatment in an appropriate posture. It can be performed. Furthermore, if the front of the practitioner is the axis of rotation, the shaft is placed between both legs of the practitioner, so compared to the case where the position is offset from the practitioner's side, rear, or center. , Easy to control the orientation.

  Since the base portion 8 of the practitioner's chair 1 has a polygonal shape of a triangle or more when viewed from above, the practitioner can easily recognize the difference between the front side portion and the rear side portion and is excellent in design. ing.

  In the practitioner's chair 1, the movement restricting portion has a tubular portion 25 that vertically penetrates the base portion 8, a restricting operation portion 26 that is passed through the inside of the tubular portion 25 and is partially exposed at the top, and a tubular portion. 25 and a contact portion 27 that is partially exposed at the bottom. When the regulation operation part 26 is pushed in, the contact part 27 descends and comes into contact with the ground. When the restricting operation part 26 is pushed again, the restricting operation part 26 projects upward, and the contact part 27 rises and separates from the ground. Therefore, the movement restricting section 24 is realized with a simple structure without requiring a complicated link mechanism.

  Note that, as another embodiment of the present invention, the size of the hole 12b of the base portion 8 may be such that it does not hinder the movable range of the operation portion 15. Further, the hole 12a of the base portion 8 may be omitted. Further, the operation portion 15 may be attached to the support leg portion 3. Further, the operation portion 15 may extend upward through the hole 12a of the base portion 8. Further, the operation portion 15 may be arranged at a position apart from the support leg portion 3. Further, it may have only the lifting operation mechanism 13 and not the movement restricting portion 24. Further, the caster 9 as the movable part may not be provided.

  Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments. The present invention can be modified in various ways without departing from the matters described in the claims.
