Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a treatment chair, and more particularly, to a treatment chair that enables an elderly person and a child to get on and off the bicycle stably and easily in dental treatment.

[0002]

2. Description of the Related Art FIG. 3 is a schematic structural view for explaining an example of a conventional dental treatment chair. In the figure, 1 is a contour seat, 2 is a leg rest, 3 is a backrest, and 4 is a headrest. 5 is a back seat, 6 is a pedestal, 7 is an elbow support, and as is well known, the back rest 3 can be turned up and down in the direction of arrow A. (Or tilted down further horizontally) to perform a prescribed treatment, wake up when gargling, etc., and perform gargling in the II position. The head 4 can be adjusted in the vertical direction (the direction of the arrow B) with respect to the backrest 3 so that the head of the patient fits the head 4 according to the height of the patient. Is done. Further, the position of the back seat 5 can also be adjusted in the up-down direction (the direction of arrow C) with respect to the back rest 3, so that the back of the patient can be adjusted according to the height of the patient or when the back rest is lowered. The adjustment is made so as to fit the back sheet 5.

[0003]

In the dental treatment chair as described above, the contour sheet 1 is normally movable up and down with respect to the pedestal 6, but inside the pedestal 6, for example, when gargling, A vacuum device or the like for sucking and discharging dirt or saliva or the like generated in the patient's cavity during dental treatment or dental treatment discharged from the patient's mouth into a spiton (not shown) is provided. The height of the contour sheet 1 cannot be reduced below the height of the pedestal 6, and therefore, the contour sheet 1 has a height that is equal to or greater than the height of the pedestal 6, even when the contour sheet 1 is at the lowest position. For elderly people and children, getting on and off the treatment chair was difficult and dangerous.

The present invention has been made in view of the above-mentioned circumstances, and has as its object to provide a treatment chair that can safely and easily get on and off the elderly and children.

[0005]

According to a first aspect of the present invention, there is provided a treatment chair having a backless and a contour seat, wherein the backrest is turned upside down with respect to the contour seat.
At the time of starting the backrest, the contour sheet can be inclined at a predetermined angle so that the front is lower than the horizontal position, so that when getting on and off the treatment chair, the elderly and children can get on and off safely and easily. It is.

According to a second aspect of the present invention, in the first aspect of the present invention, a fixed chassis is provided below the contour sheet.
The front of the contour seat moves up and down with respect to the fixed chassis about the rear as a center of rotation.

According to a third aspect of the present invention, in the first aspect of the present invention, an elbow support is fixed to the fixed chassis, and the elbow support is maintained at a predetermined position regardless of the inclination of the contour sheet. Thus, the patient's body is prevented from slipping off the treatment chair, especially when descending.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a view for explaining one mode of use of a treatment chair according to the present invention. In the drawing, parts having the same functions as those of the prior art shown in FIG. The same reference numerals as in the case of (1) are given. Thus, in the present invention, the contour sheet 1 is configured so as to be inclined forward by an angle α degrees from the horizontal position as shown in the figure, and particularly when the elderly and children get on and off the treatment chair. In addition, the contour sheet 1 is inclined forward so that when an elderly person or a child gets on or off, the feet are firmly attached to the floor surface 8, in other words, when the rider gets on the floor, the feet are completely on the floor surface. In this state, the user can sit down on the chair, and when he gets down, the feet can completely get off the chair from the floor, so that he can get on and off the treatment chair completely and easily.

Further, in the present invention, the elbow support 7 is always irrespective of the inclination of the contour sheet as described above.
It is kept in a horizontal position, especially when descending,
Make sure that the elbow rest does not tilt forward and contour sheet 1
As described above, when the patient is tilted forward, the body of the patient is prevented from slipping down. For example, if the elbow support 7 is tilted forward with the tilt of the contour seat, the elderly and children in particular do not have enough force to support the body, so that the hand on the elbow support slips and the body becomes slippery. There is a risk of slipping forward.

FIG. 2 is a main part configuration diagram for explaining an example of a mechanism for operating the contour sheet 1 as described above.
In the drawing, reference numeral 10 denotes, for example, a fixing sheet attached to a fixing portion of the treatment chair main body, and reference numeral 11 denotes a motor attached to the lower surface of the contour sheet 1, and the lot screw 12 is rotated by the motor 11. . Fixed sheet 1
A nut 13 screwed with the lot screw 12 is integrally attached to the leading end of the contour sheet 0, and the contour sheet 1 is moved up and down in the direction of arrow D by rotating the motor 11. At that time, the elbow support 7 is attached to the fixed sheet 10, and as described above, the contour sheet 1
When the arm tilts forward, the elbow rest maintains its original horizontal position, so that even when an elderly person or a child is gripped by the elbow rest 7, the hand can slip and the whole body can slip off the chair. I try not to.

In the above description, a treatment chair in which the contour seat 1 is kept horizontal and the leg rest 2 and the back rest 3 are tilted has been described as an example. It is also possible to apply the present invention to a treatment chair that tilts integrally. In this case, the contour sheet 1 tilts in conjunction with the backrest 3, so that the contour sheet 1 also tilts. What is necessary is just to keep the elbow support 7 in a horizontal state.

[0012]

As is apparent from the above description, according to the present invention, in a dental treatment or the like, a treatment chair which is gentle to both the elderly and children, particularly, the contour sheet tilts forward and backward when getting on and off. Can get on and off with the floor attached to the floor, and the elbow support, which supports the body, is kept horizontal regardless of the forward inclination of the contour seat. It is possible to provide a treatment chair that is safe for the elderly and children and that is easy to get on and off without slipping forward.
