Abstract

<P>PROBLEM TO BE SOLVED: To provide a chair for dental treatment on which an aged person and a physically challenging patient can easily sit. <P>SOLUTION: In a base 1, a mechanism capable of adjusting the vertical movement of a backrest 3, a contour seat 4 and a legrest 5 or an inclination angle, or the like, is incorporated. A step (footrest) 6 for mounting the feet of the patient is provided below the legrest 5. The legrest 5 is provided so as to be folded to the inner side in relation to the contour seat 4. By folding the legrest 5 to the inner side, the step 6 is moved back by being slid on a floor surface by a caster 7. In the state that the step 6 is moved back, the step 6 does not become an obstacle for the patient to sit on the contour seat 4. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a dental treatment chair suitable for getting on and off an elderly person or a physically handicapped person.

  FIG. 3 is an external view for explaining an outline of an example of a conventional dental treatment chair, in which 1 is a base, 2 is a headrest, 3 is a backrest, 4 is a contour seat, 5 is a legrest, 6 is a footrest (step). For the patient to sit on the dental treatment chair, turn the back to the contour seat 4, that is, take the step 6 backward and sit on the contour seat 4 as it is. It is normal to take a step 6 and then sit on the contour seat 4 while changing the direction.

  However, as described above, in the method in which the patient sits after stepping on the step (footrest) 6, the step 6 is narrow for the elderly or the physically handicapped person, so that the posture becomes unstable when riding on the step 6. There is a problem that it is not easy to sit on a dental treatment chair. There is a method of sitting on the contour seat 4 directly from the front of Step 6 without riding on Step 6, but since Step 6 protrudes forward from the legrest 5, it is still easy for elderly people and people with physical disabilities. is not.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a dental treatment chair that can be easily seated for an elderly person or a physically handicapped patient.

  The present invention relates to a dental treatment chair having a contour seat, a legrest pivotally provided at the front portion of the contour seat, and a footrest pivotally attached to a lower portion of the legrest. While providing a rest so that folding is possible inside a vertical position, it has a drive means for making the said leg rest fold inside the lower part of the said contour seat, It is characterized by the above-mentioned.

  According to the present invention, since the step (footrest) is retracted to the lower side of the contour seat when getting on and off the chair, a dental treatment chair that can be easily seated even by an elderly person or a physically handicapped patient is provided. realizable.

  In the present invention, the step (footrest) can be retracted to the lower part of the contour seat by folding the legrest inward with respect to the contour seat, and the step becomes an obstacle even for elderly people and physically handicapped patients. It is possible to safely and easily sit on a dental treatment chair.

  FIG. 1 is a perspective view of an essential part for explaining an embodiment of a dental treatment chair according to the present invention. In the figure, 1 is a base, 2 is a headrest, 3 is a backrest, 4 is a contour seat, Legrest 6 indicates a step (footrest), and the base 1 has a built-in mechanism for adjusting the backrest 3, contour seat 4, legrest 5 ascending / descending or tilting angle, etc. In the treatment, the surgeon performs the treatment from the back side or the side of the patient's head after making the entire chair easy to treat by vertically moving and tilting. A headrest 2 for supporting the patient's head is provided at the upper center of the backrest 3, and a footrest (step) 6 for placing the patient's feet is provided below the legrest 5.

  The legrest 5 is provided so as to be able to be folded inward with respect to the contour seat 4 and can be folded by any desired drive means such as an air cylinder, a hydraulic cylinder, or a motor. The drive means may be anything that can be driven to adjust the angle (rotation) of the leg rest 5 with respect to the contour seat 4. In the case of the illustrated example, as a driving means, the air cylinder 10 is attached to the contour seat 4 side, and the piston is attached to the legrest 5 side by the connecting portion 11. By actuating the air cylinder 10, the legrest 5 can be bent inward and the step 6 can be moved backward. The step (footrest) 6 is rotatably supported at the lower part of the legrest 5 so that the rear part thereof serves as a rotation axis, and the surface on which the foot is placed when the legrest 5 is vertical. The rotation is restricted so as to take a horizontal position (see the dotted line position), and this substantially horizontal position is set as a lower limit, and a healthy person gets on and off in this state. In this state (dotted line position), since the step (footrest) 6 protrudes forward from the front part of the contour seat 4, this step 6 becomes an obstacle for an elderly person or a handicapped person. In the present invention, the leg rest 5 is further folded below the contour seat 4 from the vertical state (see the solid line position) so that the step 6 does not protrude forward from the contour seat 4.

  In a preferred embodiment, the caster 7 is attached to the lower surface of the step 6, and when the legrest 5 is folded inward, the floor surface can be slid by the caster 7 to retract the step 6. In the state where Step 6 is retracted, Step 6 does not protrude forward from the front part of the contour seat 4, and Step 6 does not get in the way when the patient sits on the contour seat 4. After the patient sits, step 6 is pulled forward by returning the legrest 5 to a predetermined position, and the foot can be put on step 6.

FIG. 2 is an explanatory view of an example of the usage state of the dental treatment chair described in FIG. 1, in which 8 is a floor surface, 9 is a raised surface, and in this embodiment, the dental treatment chair is installed. The floor 8 is lower, and the other parts similar to those in FIG. When the patient rides on the treatment chair, the floor surface (the raised surface) 9 is higher than the floor surface 8, and the patient can ride on the dental treatment chair from the raised surface 9. In other words, if there is no raised surface 9, the patient must sit in a chair with a height H _{1 above} the floor 8, but if there is a raised surface 9, this raised surface H ₂ (H ₂ <H ₁ ) Can sit on a chair of height. Furthermore, an inclined surface S is formed between the raised surface 9 and the floor surface 8, and the step 6 can be drawn to the lower side of the contour sheet 4 by using the inclined surface S.

  If a person with a physical disability is not easy to sit on the dental treatment chair at the height of H shown in FIG. 1, the leg rest 5 is folded inward as shown in FIG. The seat 4 is lowered. Thereby, the step 6 slides back on the slope with the caster 7. Not only does Step 6 not get in the way, but the seating surface is lowered so that the patient can easily sit on the raised surface 9.

It is a principal part perspective view for demonstrating one Example of the chair for dental treatment of this invention. It is a figure for demonstrating an example of the use condition of the dental treatment chair of this invention. It is an external view for demonstrating the outline of an example of the conventional chair for dental treatment.
