  As shown in FIGS. 2 and 3, the dental table 1 having the holder moving mechanism according to the present invention accommodates or stores a dental instrument (hereinafter referred to as “handpiece”) 2 as a rod-like instrument. A configuration is provided in which the angle of the holder 3 to be suspended can be adjusted while the head 21 of the handpiece 2 is fixed. With this configuration, the dental table 1 can be provided as a dental table 1 that is easy to grasp when a dentist or the like uses the handpiece 2. Furthermore, the problem that the head 21 protrudes too much from the dental table 1 and faces the dentist or the like is solved. Hereinafter, a specific configuration will be described in detail.

  As shown in FIG. 1, the dental table 1 includes a holder 3 having a sleeve 31 as a holding portion that can hold a handpiece 2 composed of a head 21 and a body 22, and the holder 3 connected to form a circular arc. The arm 11 has an arcuate portion A that expands and contracts, and a table body 10 to which the arm 11 is attached. A handle 12 for facilitating movement of the dental table 1 by a dentist or the like is provided on the side of the table body 10 on the side where the holder 3 is located. In addition, the description of the leg part of the dental table 1 is omitted in FIGS.

  As shown in FIG. 1, the sleeve 31 provided in the holder 3 is detachably provided and has a hole 31 a having a diameter capable of inserting and holding the handpiece 2. In particular, the hole 31a has a wide entrance and a constricted shape so that the handpiece 2 can be held inside so that a dentist or the like can easily use the handpiece 2 by pulling it out of the holder 3. Further, when the holder 3 is viewed from the side, it can be confirmed that the hole 31a has a shape communicating with the outside in a part of the depth direction (see also FIG. 4).

  The holder 3 includes a plurality of detachable sleeves 31 as described above, thereby forming a substantially rectangular parallelepiped structure having a plurality of holes 31a. The material of the holder 3 and the sleeve 31 may be made of metal or synthetic resin. The holder 3 has a substantially rectangular parallelepiped-shaped central portion in the longitudinal direction, and is connected to an arm 11, specifically, an open end of a slide arm portion 112 described later. By connecting to the slide arm part 112 at the longitudinal center part of the substantially rectangular parallelepiped shape, it is possible to prevent the left and right end parts of the holder 3 from being bent.

  Further, the shape of the sleeve 31, particularly the shape of the hole 31 a formed in the sleeve 31, is configured as a shape corresponding to the type of the handpiece 2 to be held such as an air turbine, a micromotor, or a multi-syringe. For this reason, when attaching to the holder 3, the sleeve 31 corresponding to the kind of handpiece 2 required for treatment can be prepared, and the sleeves 31 having different shapes can be exchanged on the holder 3. . The sleeve 31 removed from the holder 3 can be easily cleaned.

  The arm 11 has an attachment arm portion 111 attached to the lower surface of the table body 10. Further, the mounting arm portion 111 includes a slide arm portion 112 that is slidable in an arc shape outward from the table body 10 and forms an arcuate portion A with a part of the mounting arm portion 111. Yes. The holder 3 is connected to the open end of the slide arm 112 that is opposite to the connecting portion with the mounting arm 111.

  As shown in FIG. 2, the arc-shaped portion A is a part of the mounting arm portion 111, and is formed along the arc-shaped portion 111 a formed toward the outside where the handle 12 is located, and along the arc-shaped portion 111 a. The slide arm portion 112 is formed by sliding and is formed in an arc shape similar to the arc-shaped portion 111a. In particular, the arc-shaped portion A has a structure in which the arc-shaped portion 111a of the mounting arm portion 111 is cylindrical and the slide arm portion 112 is accommodated inside the cylinder.

  As a result, as shown in FIG. 3, in other words, by the expansion and contraction of the arc-shaped portion A (in FIG. 3, the arc-shaped portion A is in an extended state), in other words, from the inside of the mounting arm portion 111 to the slide arm portion 112. The holder 3 moves in an arc shape by a sliding operation in which is pulled out or accommodated. Then, as can be understood from the comparison between FIG. 2 and FIG. 3, the holder 3 changes the angle of the side view, but the fixed point that is the center of the virtual circle formed by the arcuate locus on which the holder 3 moves is It is formed. This fixed point is located above the holder 3 and in front of the handle 12 of the table body 10. In particular, when the handpiece 2 is held by the sleeve 31 of the holder 3, the fixed point that is the center of the virtual circle is located at the head 21 of the handpiece 2. That is, even if the holder 3 moves in an arc shape and changes its angle, the head 21 of the handpiece 2 remains stationary.

  Therefore, in the present invention, the holder 3 can be moved in an arc shape by the sliding operation of the slide arm portion 112, and the angle of the holder 3 in a side view can be changed. In particular, even if the angle of the holder 3 in a side view is changed and the body 22 of the handpiece 2 is raised or tilted, the position of the head 21 of the handpiece 2 can be fixed. With such a configuration, a dentist or the like can determine the holder 3 at an angle determined as an easy-to-operate position and can handle the handpiece 2 held on the holder 3 at an angle that is easy to grasp. It is possible to prevent the head 21 from protruding too far from the dental table 10 toward the dentist or the like. In particular, by configuring the sleeve 31 to have a shape corresponding to the type of the handpiece 2, the head 21 is always positioned at the center of the virtual circle regardless of the size and shape of the handpiece 2 depending on the type. It is possible to make it immobile.

  Further, since the arc-shaped portion A has a structure in which the arc-shaped portion 111a of the mounting arm portion 111 is cylindrical and the slide arm portion 112 is accommodated inside the cylinder, the holder 3 can be taken in a side view. An angle is restrict | limited only to the angle which makes it the state (refer FIG. 3) which raised from the state (refer FIG. 2) which fell the body 22 of the handpiece 2. FIG. The arm 11 is provided with a fixing means capable of fixing a slide operation in which the slide arm part 112 is pulled out or housed from the inside of the mounting arm part 111 at an arbitrary position.

  As the fixing means, for example, as shown in FIGS. 2 and 3, a protrusion 1121 is provided on the slide arm 112, and a hole 1111 that fits or engages with the slide arm 112 is provided on the mounting arm 111 so as to have an appropriate length. An example in which the arcuate part A is expanded and contracted and then fixed by fitting or engaging between them can be given. In addition, for example, an example in which the mounting arm portion 111 and the slide arm portion 112 are screwed after the arc-shaped portion A is expanded and contracted to an appropriate length can be given. Through these, a dentist or the like can determine the angle of the side view of the holder 3 (the degree of tilting of the handpiece 2) by himself / herself at a position where treatment is easy.

  Here, in the present invention, as shown in FIG. 4, on the lower surface of the table main body 10, a rotating portion 41 that rotates along the surface and a screw that can attach the arm 11 (particularly, the mounting arm portion 111) or the like. It is preferable that a rotation means 4 comprising an attachment portion 42 provided with In the present embodiment, the rotating means 4 is disposed at a substantially central portion of the lower surface of the table body 10 on the handle 12 side. When the arm 11 is attached to the rotation means 4, the arm 11 can be rotated with respect to the table body 10 by the rotation unit 41. Specifically, as shown in FIG. 4, the rotation part 41 is sandwiched between the table body 10 and the attachment part 42 and is freely rotatable. Moreover, the rotation part 41 and the attachment arm part 111 are integrally formed.

  Thereby, the holder 3 can be positioned at an arbitrary angle in a plan view with respect to one side of the table body 10, for example, the side where the handle 12 is provided. Accordingly, the dentist or the like can adjust the position of the holder 3 to the position where the holder 3 is easy to operate, even in the angle in plan view. For example, when a dentist with a different handedness or the like uses it after using it by a certain dentist, the holder 3 can be changed to a position at which the user can easily perform the treatment even at an angle in plan view.

  In the above-described embodiment, the configuration in which the sleeve 31 is detachably attached to the holder 3 has been described. However, the present invention can also be configured by providing a holder having a hole directly formed in the holder. In this case, the holding portion and the shape of the hole may be provided differently for each type of instrument. Thereby, regardless of the types of instruments having different sizes and shapes such as an air turbine, a micromotor, and a multi-syringe, the head can always be positioned at the center of the virtual circle and can be fixed.

  Therefore, in the dental table 1 provided with the holder moving mechanism according to the present invention, the holder 3 is moved by the expansion and contraction of the arc-shaped portion A of the arm 11, the angle is changed, and the body 22 of the handpiece 2 is raised. And can be in a defeated state. At that time, since the head 21 can be fixed around the center of the virtual circle, the handpiece 2 can be easily grasped and the direction of the head 21 can be maintained appropriately.

  The configuration of the arm 11 includes an attachment arm portion 111 attached to the lower surface of the table main body 10 and a slide arm portion 112 that slides relative to the attachment arm portion 111. And the support function of the holder 3 can be borne. The expansion / contraction function of the arc-shaped portion A can be achieved by a simple mechanism of sliding the slide arm portion 112 with respect to the mounting arm portion 111. Since the mounting arm portion 111 is rotatable with respect to the table body 10, the holder 3 can be positioned at an arbitrary angle even when the table body 10 is viewed in plan.

  From the above, it can be understood that according to the present invention, it is possible to provide the dental table 1 that makes it easy to grasp the handpiece 2 and allows a dentist or the like to perform various treatments at an appropriate position.

  Here, the present invention can adjust the mounting position of the arm on the lower surface of the table body. That is, the table body after considering how far the center of the virtual circle that does not move even if the angle of the holder changes is positioned away from the table body and how high the table body is The mounting position of the lower arm can be determined.

  The connection position of the holder to the arm is not limited to the open end on the opposite side of the table body, and may be connected in the middle of the arm, for example. The connection position of the holder to the arm can be determined in consideration of the position of the center of the virtual circle that does not move even if the angle of the holder changes. In addition, for example, by providing holes in various portions of the mounting arm part and the slide arm part, and screwing the connection part of the holder into the hole, the holder can be connected to a position in the middle of the arm.

  Furthermore, the shape of the holder is not limited to the substantially rectangular parallelepiped shape described above. Moreover, when a holder is a substantially rectangular parallelepiped shape or another shape, it is not limited to the structure connected with an arm in the center part, You may be the structure connected with an arm at the edge part of a holder. Also in this case, the holder can be provided with sufficient strength by selecting a material or the like.

  Further, by color-coding the holder and the holding portion (sleeve), effects such as position recognition of the sleeve itself and easy understanding of the inner diameter shape can be obtained, and visibility of a place where the instrument should be held can be improved. Further, by color-coding the sleeves for each type of instrument to be held, it is possible to contribute to an improvement in visibility such as which instrument should be held by which sleeve. Color coding should be distinguished by brightness and color. It can also be color-coded by monotone, gradation, pattern, etc. You may color-code using LED etc.

  Although one embodiment of the present invention has been described above as an example, the present invention can be modified in various ways without departing from the scope of the claims. For example, in the above-described embodiment, an example in which the holder moving mechanism according to the present invention is applied to a dental table has been described. However, a table or the like provided with a holder moving mechanism for holding a rod-like instrument used for treatment by giving some function to the head is not limited to dentistry, and may be applicable in other medical departments. Furthermore, a table or the like provided with a holder moving mechanism for holding a rod-like instrument used for the treatment by giving a certain function to the head can also be used as a table used in esthetic or other whole body cosmetic procedures.
