Abstract

PROBLEM TO BE SOLVED: To easily hold an instrument holder which can be rotated with respect to a horizontal direction of a doctor table or an assistant table at a desired angle position of a dentist easily and vertically with respect to the table. Provided is a dental instrument holder that prevents the holder from loosening as easily as possible. An instrument holder 4 is provided that is pivotable in the vertical direction with respect to an instrument holder mounting base 8 that is pivotably mounted in a horizontal direction with respect to a table 1 used by a dentist or an assistant. A lock lever 9 having a locking piece 9a for engaging with a locking groove 8e provided in the mounting support plate 8b of the instrument holder mounting base 8 is provided rotatably with respect to the instrument holder 4. Thus, the instrument holder 4 is freely rotated or locked by the lock lever 9. [Selection] Figure 2

Description

The present invention relates to a mechanism for adjusting the standing angle of an instrument holder provided on a table on which a treatment instrument used by a dentist or assistant is placed.

  When the dentist or assistant uses the instrument A such as a handpiece, the dentist or assistant treats the patient in consideration of the arrangement of treatment instruments that are easy to treat, depending on the treatment position on the patient. Therefore, treatment is performed by adjusting the take-off angle of the instrument A or the like to be used.

As a conventional instrument holder used in such a case, for example, there is an invention disclosed in Japanese Patent Application Laid-Open No. 2008-178504. In the present invention, the holder 3 can rotate in the horizontal direction with respect to the table 1 at the portion of the rotary shaft 311 with respect to the table 1, and the instrument receiver 313 can rotate with respect to the rotary shaft 311. Therefore, it can be rotated in the vertical direction. The instrument 2 is placed on the attachment 32, and the instrument 2 inserted into the instrument receiver 313 can be displaced left and right and up and down, so that it is suitable for dentists and assistants. It is possible to direct the instrument 2 to the side.

The instrument receiver 313 is brought into contact with a sliding contact surface 313h of the instrument receiver 313 with a brake shoe 312d attached to the holder arm 312 (see FIGS. 6 to 8). It is rotatable with respect to the bearing portion 312c of the holder arm 312 and is held at a position where the rotation is stopped by the frictional resistance of the brake shoe 312d even if the holder arm 312 is rotated. An angle is secured.

JP 2008-178504 A

By the way, in the conventional dental instrument holder as in Patent Document 1, if the adjustment of the standing angle of the instrument holder is to be performed with a light force, it is necessary to weaken the frictional force due to tightening and pressing. In such a case, when the dentist or the like returns the instrument to the instrument holder, the instrument tilts downward with respect to the weight of the instrument.
Further, when a dentist or the like takes out the instrument from the instrument holder, there is a problem to be solved such that when the instrument hose is lifted, the holder itself moves upward.

Furthermore, when touching the body of the person to be treated, there has been an urgent need to solve problems such as the angular position of the holder itself moving.
As a method for solving the above problems, it is necessary to increase the frictional force by tightening or pressing on the holder, but the frictional force must be increased to make it difficult to adjust the standing angle. It was difficult.
In order to perform further tightening and pressing, tightening with a screw or the like is conceivable, but in this case, there is a problem that even if tightening with a constant force, it gradually loosens with time.

The present invention is intended to solve the above-described problems, and an object of the present invention is to easily provide an instrument holder that is rotatable with respect to the horizontal direction of a dentist table or an assistant table with respect to the table. It is an object of the present invention to provide a dental instrument holder that can be freely rotated in the vertical direction and that can be securely held at a desired angle position of a dentist and that the holder is not easily loosened.

The dental instrument holder of the present invention is intended to achieve the above-mentioned purpose, and its means is provided on a table used by a dentist or an assistant and can be rotated in a horizontal direction with respect to the table. An instrument holder mounting base to be mounted, and a mounting support plate attached to the instrument holder mounting base and having a locking groove;
An instrument holder provided so as to be rotatable in the vertical direction with respect to the instrument holder mounting base, and a locking groove provided in the mounting support plate so as to be rotatable with respect to the instrument holder. A locking lever having a locking piece to be engaged with the locking lever, releasing the locking piece by pressing the locking lever and removing the locking piece from the locking groove provided in the mounting support plate, and making the instrument holder rotatable, The instrument holder can be locked by releasing the lock lever so that the lock piece is locked in a locking groove provided in the mounting support plate.

  The dental instrument holder of the present invention is tightened like the conventional dental instrument holder and does not hold the instrument holder by frictional force by pressing, but securely holds the instrument holder. Therefore, when the dentist returns the instrument to the instrument holder, the instrument does not tilt downward with respect to the weight of the instrument. When the instrument hose is removed, the holder itself does not move upward when the instrument hose is lifted.

Furthermore, since the instrument holder is securely locked, the angular position of the holder itself does not move even if the body of the patient is touched.
From the above, the dentist or assistant can operate the instrument at a desired appropriate angular position without adjusting the frictional force by tightening or pressing on the holder.

It is a perspective view in the state where the dental instrument holder concerning the present invention was attached to the table for dentists or assistants. It is sectional drawing of the state which locked the instrument holder main body. It is sectional drawing of the state which unlocked the instrument holder main body.

Hereinafter, an embodiment of a dental instrument holder according to the present invention will be described with reference to the drawings.
