TECHNICAL FIELD OF THE INVENTION
The present invention relates to a dental treatment unit, more specifically, a handrail that can safely support the body when a disabled person, an elderly person, etc., gets on and off a dental treatment chair, and when mouthwashing (gargle) during treatment. The present invention relates to a dental treatment unit including a member.
[0002]
[Prior art]
FIG. 4 is an overall configuration diagram showing an example of a dental treatment unit to which the present invention is applied. In the drawing, reference numeral 10 denotes a dental treatment unit, and the unit 10 includes a treatment chair 1, a work table 2, a spitton 3, It comprises an operating light 4, an instrument holder 5, a foot switch 6, an instrument holder 7 for assistants, etc. The instrument holder 5 accommodates various instruments 8 used in dental treatment. As is well known, in performing dental treatment, a patient sits on a chair and fixes his / her head on an abutment 9 to receive treatment. During the treatment, the surgeon moves the treatment chair 1 up and down, tilts, tilts, etc., so that the patient is in a posture that facilitates treatment, and performs the treatment.
[0003]
[Problems to be solved by the invention]
In the dental treatment unit as described above, the patient has to get on and off the treatment chair 1 by himself. At that time, the disabled person, the elderly person, etc. are very unstable because there is nothing to support the body around them. It was dangerous. Similarly, the mouthwash (gargle), which is sometimes performed during the treatment, was very unstable and dangerous because there was no support for the body.
[0004]
The present invention has been made in view of the above circumstances, and particularly provides a dental treatment unit that enables a disabled person or an elderly person to get on and off stably and gargle with peace of mind (in a stable state). It was done for the purpose of doing.
[0005]
[Means for Solving the Problems]
The invention according to claim 1 is a dental treatment unit including a dental treatment chair that can be raised and lowered and a spitton disposed on one side of the treatment chair. An L-shaped handrail member having a vertical portion rotatably erected on the side on which the spittons are disposed and a horizontal portion extending horizontally above the vertical portion, wherein the handrail member is Between a first position in which the horizontal portion extends above the leg rest of the treatment chair in a direction substantially perpendicular to the treatment chair, and a second position in which the treatment portion extends parallel to the side of the treatment chair. in lockable der pivotable in and in the first position and the second position is, the vertical section the lower end of the handrail member of the L-shaped, is pressed downward by the spring member, and the first And the second position is locked so that it cannot rotate. The lock by pulling the section is released is obtained and characterized in that rotatable.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a schematic diagram showing a main part of a dental treatment unit according to an embodiment of the present invention. In FIG. 1, 1 is a dental treatment chair, 3 is a spitton, and these are as described in FIG. In addition, the spittons 3 are well known in the related art, and the spittons 3 may be integrated with the treatment chair 1 (chair mount) or may be separate bodies. 20 is a handrail members added by the present invention,該手sliding member 20 includes a vertical portion 20 ₁ and the horizontal portion 20 ₂ is formed in an L-shape, the vertical portion 20 _1, either one of the treatment chair 1 It is rotatably installed by a chair mount on the side of (the side where the spittons are arranged).
[0009]
Handrail member 20 is in its first position shown by a solid line in FIG. 1, i.e., in the horizontal portion 20 ₂ is the leg rest 1 _part above the treatment chair 1 of the handrail member 20, substantially in a direction transverse to said treatment chair 1 a position a which extend at right angles, a second position indicated by a broken line in FIG. 1, i.e., the position B the horizontal portion 20 ₂ of the handrail member 20 to extend parallel to the said treatment chair 1 in the side of the treatment chair 1 , And is locked so as not to rotate in the first and second positions.
[0010]
Thus, the patient, when getting on and off the treating chair 1, treating the leg rest 1 ₁ of the chair 1, as shown by chain line in FIG. 1, the beat state, in this state, horizontal handrail member 20 the part 20 ₂ is fixed to the solid line position of FIG. 1 (the first position). Patients in this state, grab the horizontal portion 20 ₂ of the handrail member 20, inserting the legs into the space between the horizontal portion 20 ₂ and the chair 1, then, the proper position of the center by shifting the body Moving. Thereafter, since the patient is lying on the treatment chair 1, the operator or assistant pulls up the handrail member 20 to unlock the handrail member 20, turns the handrail member 20 by approximately 90 ° in the direction of the arrow, and moves the chain line position (second line position). When the hand is released in this state, the handrail member 20 is automatically locked at that position as described later.
[0011]
As described above, the horizontal portion 20 ₂ of the handrail member 20, in the state and to a second position indicated by chain line in the figure, and, while the state sleeping patients, performing dental treatment, dental treatment in the middle of, sometimes, by the treatment chair 1 in raised condition, performs the mouthwash (gargle) and the like, this time, the horizontal portion 20 ₂ of the handrail member 20, as described above, shown in chain line in FIG. because the position, the patient, gargle can the be caught on the horizontal portion 20 _2, in a stable state, it is possible to gargle with confidence.
[0012]
FIG. 2 is a view for explaining an attachment mechanism of the handrail member 20. In the figure, reference numeral 30 denotes a cylindrical body fixed to the treatment chair 1, and the lower end of the vertical portion of the handrail member 20 is inserted into the cylindrical body 30. It is supposed to be. 31 is a spring member disposed in the cylindrical body 30 by the spring member 31, the該手sliding member 20 has given gel strength under press down direction to the handrail member 20. 32 rotatably guided by and said first location between the該手sliding member 20 to the first and second positions in cooperation with the guide groove 21 provided in the vertical portion 20 ₁ of the handrail member 20 And a pin fixed to the second position so as not to rotate.
[0013]
FIG. 3 is an enlarged view showing the guide groove 21 of the handrail member 20 shown in FIG. 2 in detail. As shown in FIG. 3, the guide groove 21 has vertical guide groove portions 21 ₁ and 21 ₂ , consists horizontal guide groove 21 ₃ which connects the guide groove ₂₁ 1, 21 ₂ of the lower end, between the vertical guide groove 21 ₁ and 21 ₂ are substantially 90 ° apart. Therefore, when the pin 32 is engaged with the vertical guide groove 21 _1, the horizontal portion 20 ₂ of the handrail member 20 is in a first position shown by a solid line in FIG. 1, the vertical guide groove 21 ₂ is in the second position shown by the dashed line in FIG. 1 and is fixed (locked) so as not to be rotatable at both positions. In this locked state, increasing your handrail member 20, the pin 32 engages the horizontal groove 21 _3, in this state, it is possible to rotate the該手sliding member 20 to the other locking position.
[0014]
【The invention's effect】
As is clear from the above description, according to the present invention, it is possible to provide a treatment chair that enables a patient with a physical disability, such as a disabled person or an elderly person, to get on and off with peace of mind and to gargle with peace of mind. Further, since the handrail member is configured to be lifted upward and pivoted, even when a force is applied to push down the handrail member when the handrail member is grasped, the handrail member does not move at all. Therefore, it can be grasped by the handrail member with ease.
