[Prior art]

 In general, a human head model for dental training, as shown in FIG. 8, attaches a cheek mask member 100a made of a flexible synthetic resin to a face head body 100 made of a synthetic resin or aluminum. An articulator equipped with upper and lower jaw dentition models (jaw model) is attached to the inside of the mouth 100c of the cheek mask member 100a. The articulator and the face head 100 to which the cheek mask member 100a is attached are aligned and attached to the support portion.

FIG. 9 and FIG. 10 show a structure for attaching a face head portion having a cheek mask member attached to the main body supporting portion, and FIGS. 11 and 12 show a structure for attaching an articulator to the main body supporting portion. There is. As shown in FIG. 9, on the inner surface of the facial head portion 100, a standing groove is provided on a bottom surface 102a on which a locking groove 101a is provided, and three connecting pins 101 each having a pointed tip are projected. An L-shaped connecting piece 102 formed by raising 102b is fixed, and three connecting pins 101 of this L-shaped connecting piece 102 are formed on a base plate 103a of the main body supporting portion 103 to form three connecting pins. By inserting into the holes 103b and 103b ', the face head 100 is coupled to the main body supporting portion 103 provided with the base plate 103a. Here, as shown in FIG. 10, the base plate 103a has locking holes 105a corresponding to the respective connection holes 103b formed in the portions where the two connection holes 103b are formed, and is projected from the base plate 103a. The slide locking member 105 having the bent portion formed as the operating portion 105b is superposed, and the locking member 105 has elasticity of the spring 104 so that the locking hole 105a comes to a position that partially closes the connecting hole 103b. Energize.

Therefore, according to this structure, when the three connecting pins 101 of the L-shaped connecting piece 102 are inserted into the above-described three connecting holes 103b and 103b ', the base plate 103a of the main body supporting portion 103 is inserted. The two connecting pins 101 inserted into the two connecting holes 103b formed in the above are inserted into the hole portion 105a of the slide locking member 105 through the two connecting holes 103b, and further force is applied to insert the two connecting pins. The pin 101 moves through the hole position of the hole portion 105a against the elastic force of the slide locking member 105, then penetrates and projects, and then the slide locking member 105 is moved to the original position by the elastic force of the spring 104. Since it goes back up to this point, it is pinched by the two connecting holes 103b at this time, and the locked state is maintained. The other one coupling pin 101 is inserted into the other connecting holes 103b and 103b 'of the base plate 103 for alignment.

Further, when the face head 100 is removed from the base plate 103 a of the main body support 103, the slide lock member 105 can be pulled out against the elastic force of the spring 104 to slide lock the slide lock member 105. The hole 105a of the member 105 moves to allow the two connecting pins 101 to be pulled out from the two connecting holes 103b, so that the face head 100 is supported by the main body while maintaining the state in which the operating portion 105b is pulled out. It may be extracted from the portion 103.

On the other hand, the structure of attaching the articulator to the main body supporting portion will be described. As shown in FIG. 11, the articulator 200 with the jaw model 201 attached has a hole 202a formed at the center thereof. The piece 202 is protruded from the upper part, and a pair of connecting rails 203 into which both ends of the connecting piece 202 of the articulator 200 are fitted are attached to the base plate 103a of the main body supporting portion 103 attached to the neck of the body model 300. A hole 206 is formed in the center of the coupling rail 203, and the lock ball 204 and the compression spring 205 shown in FIG. 12 are accommodated in the hole 206, and the lock ball 204 is constantly operated by the elastic force of the spring 205. When biased upward, the hole 206 is formed smaller than the outer diameter of the lock ball 204 so that the lock ball 204 does not fall out of the hole 206. . Therefore, according to such a structure, the coupling piece 202 protruding from above the articulator 200 is directed toward the direction shown by the arrow (dashed line) in FIG. 12 into the connecting rail 203 of the main body supporting portion 103 until the hole 202a is aligned with the hole 206 of the base plate 103a, as shown in the sectional structure view of FIG. The rock ball 204 accommodated in the hole 206 is fitted into the hole 202a formed in the coupling piece 202 of the articulator 200 to be fixedly coupled, and thus the articulator 200 fixedly coupled is moved away from the main body supporting portion 103. By pulling out so as to resist the elastic force of the compression spring 205 as described above, the coupling between the coupling piece 202 of the articulator 200 and the coupling rail 203 is released, and it is possible to remove it.

[0007]

[Problems to be solved by the device]

 However, such a human head model has a structure in which the articulator is attached by inserting and removing the articulator connecting pieces into and from the pair of connecting rails provided on the main body supporting portion, so workability during attachment and detachment is improved. And is in the opposite relationship to stability at the time of binding. That is, the distance between the pair of connecting rails provided on the main body supporting portion side needs to be adjusted correctly with respect to the connecting piece protruding from the articulator. If the clearance is smaller than the width of the coupling piece 202 or if the elastic force of the compression spring 205 that pushes up the lock ball 204 from below is strong, the articulator 200 is firmly attached and fixed, but it is difficult to remove it. If the clearance between the pair of rail members 203 is large, or if the elastic force of the compression spring 205 that pushes up the lock ball 204 from below is weak, it is easy to remove, but it is easy to remove. there were.

In addition, with such a structure, it is troublesome to adjust the gap between the pair of coupling rails 203 with respect to the coupling piece 202 of the articulator 200, which increases assembly and processing costs. There was a problem. Further, in such a mounting structure, when the articulator 200 is detached from the main body support portion 103, an operation of pulling out the articulator 200 from the main body support portion 103 is necessary. When the insert-fitting connection with 203 is strong, there is a high possibility that the articulator 200 will be carelessly removed at that time, and if the articulator 200 is removed, the jaw model 201 etc. will be destroyed. There was something to do.

The present invention solves the above-mentioned conventional problems and allows the articulator to be attached / detached to / from the main body of the human head model by a simple operation to firmly bond and easily remove the articulator and the human head. It is possible to provide a safe articulator mounting structure that prevents the articulator from accidentally falling and dropping even when the joint of the model is released, and a human head model equipped with this articulator mounting structure.

FIG. 1 shows a human head model as seen from below with the articulator being removed by rotating the face head backward to expose the articulator connection.

The human head model 3 has a main frame 31 that constitutes a main body supporting portion inside the face head 3a to which a mask member 3b is attached, and an auxiliary frame 32 fixedly connected to the main frame 31. The articulator 2 is removably attached to the connecting piece 4 formed by bending the lower part of the articulator, as will be described later. In the articulator 2, as shown in this figure, the upper and lower members 2a and 2b are openably and closably connected by a hinge portion 2c, the jaw model 1 is mounted therein, and the base 21 is mounted on the upper surface of the upper member 2a. . A connecting pin 5 and a hook member 9 are provided on the base 21 in a protruding manner, and a connecting hole is formed in a connecting piece 4 formed by bending the tip of an auxiliary frame 32 fixed to the main frame 31. 4a is formed and the connecting means 7 is incorporated.

FIG. 2 is a diagram for explaining the connecting means. The connecting piece 4 has a hole portion 8 having an opening having a size sufficiently larger than that of the hook member 9 shown in FIG. 1, and a connecting hole 4a is formed above the hole portion 8. The connecting hole 4a has an inner diameter slightly larger than the outer diameter of the connecting pin 5 and has a sufficiently large vertical opening. On the side opposite to the connecting pin 5, the operating piece 71 is provided with a base piece 72. A vertically extending L-shaped locking member 7A is provided by being overlapped. The actuating piece 71 of the locking member 7A is arranged so that the base piece 72 is made rotatable with respect to the connecting piece 4 by the pivot shaft 7a and a part of the vertically long connecting hole 4a, that is, the upper part thereof is closed. The other end of the operating piece 71 exerts a pulling force in the direction of closing the connecting hole 4a by the spring 12 attached between the operating piece 71 and the connecting plate 4. Further, a projecting piece is formed on the side of the operating piece 71 opposite to the side where the spring 12 is provided, and the tip of the projecting piece is bent to form the operating portion 6a of the operating lever constituting the coupling releasing mechanism 6. ing.

The actuating piece 71 has a thickness corresponding to the small-diameter locking groove 5a provided on the outer circumference of the connecting pin 5 inserted into the connecting hole 4a when the articulator 2 is connected. When the connecting pin 5 provided on the articulator 2 side is inserted into the connecting hole 4a, the cut arc 7b is formed so as to extend from the connecting hole 4a. The pin 5a is engaged with a locking groove 5a formed on the outer periphery of the pin 5a so that the pin 5a can be pinched.

In this embodiment, the connecting means 7 is composed of a combination of the locking member 7A and the connecting hole 4a. As shown in FIG. 3, a pivot pin 11 is provided at the bent end of the auxiliary frame 32 fixed to the main frame 31, and is fixed inside the facial head 3a at the tip thereof to support the facial head 3a. A head support frame 33 is rotatably mounted, and a mounting portion 34 having a bolt insertion hole is provided at a lower portion of the main frame 31, and the mounting portion 34 is mounted on a neck of a human body model or a training table. It can be attached by bolting to.

The retaining hole 8 formed below the connecting hole 4a of the connecting piece 4 is provided when the connecting pin 5 of the articulator 2 is inserted into the connecting hole 4a and is clamped by the locking member 7A. As shown in FIG. 3, the entire hook member 9 protruding from the articulator 2 is inserted and the articulator 2 and the connecting piece 4 are tightly coupled together without a gap. The hook member 9 protruding from the articulator 2 is composed of a rail strip member having a groove formed to form a locking claw 9a. When the articulator 2 is disengaged from the connecting hole 4a, as shown in FIG. 4, the articulator 2 is hooked and held on the edge of the retaining hole 8.

When forming the locking claw 9 a on such a hook member 9, if it is formed on the side away from the connecting pin 5, that is, below the connecting pin 5 in FIGS. It is possible to insert the connecting pin 5 into the connecting hole 4a after the locking claw 9a is hooked on the lower end of the opening edge 8a of the hole 8, and when the connecting pin 5 is removed from the connecting hole 4a, Since the locking claw 9a of the hook member 9 can be hooked and held on the opening edge 8a of the punched-out portion 8, it is possible to prevent accidental disengagement. Such a locking claw 9a of the hook member 9 is particularly useful when the weight of the articulator 2 is large, or when the articulator 2 is attached or detached at a position or state where workability is poor.

In the example of FIGS. 3 and 4, the connecting pin 5 projecting from the base 21 of the articulator 2 has a locking groove 5a formed on the entire outer periphery, and the tip thereof is tapered. Although it has a head portion 5b, as shown in FIG. 6, the head portion 5b is sharpened like a hook to form a locking groove 5a, but as shown in FIG. What has a spherical shape and has a locking groove 5a formed by constricting the base is used. If the type of these connecting pins is different, a connecting means having a differently shaped locking member is adopted. To be done.

In the example shown in FIG. 2, the decoupling mechanism 6 of the one connecting means 7 is configured by providing an operating lever 6 integrally formed at the end of the operating piece 71 of the above-mentioned locking member 7A. However, it is not limited to such an operation lever 6 and an operation button may be provided. Such a human head model 3 has a structure in which the face head 3a is rotatably pivotally attached to the main body supporting portion 31 by the pivot pin 11, so that it can be used during the training shown by the solid line in FIG. As shown by the imaginary line (two-dot chain line) from the state, if the face head 3a is rotated backward, the face head 3a is rolled backward together with the cheek mask portion 3b attached to it. Since the entire part of the articulator 2 that has been lifted up and installed inside can be exposed, it is convenient to replace the articulator 2 as it is.

Next, a description will be given of how to use the articulator mounting structure having such a structure. The articulator 2 is directly opposed to the connecting piece 4 of the main body supporting portion 31, and the connecting pin 5 of the articulator 2 is inserted into the connecting hole 4a. At this time, since the hook member 9 protruding from the articulator 2 needs to be fitted into the hole 8 of the connecting plate 4, it functions as a positioning member. At this time, if the engaging claw 9a of the hook member 9 is hooked to the lower edge of the hole 8 as shown in FIG. 4, the articulator 2 can be temporarily fixed to the connecting piece 4, so that the connecting work can be performed. There is no risk of the articulator 2 being accidentally dropped.

Further, since the tip of the connecting pin 5 is a pointed tip, it can be smoothly inserted into the connecting hole 4a formed on the side of the connecting means 7, and the locking member 7 is spouted at the tip of the connecting pin 5. When the connecting pin 5 is pushed into the connecting hole 4a and protrudes through the connecting hole 4a while being moved upward against the elastic force of the ring 12, the locking member 7 is moved by the elastic force of the spring 12. In order to return to the original state, the locking member 7 is fitted into the locking groove 5a of the connecting pin 5 protruding from the connecting hole 4a from above, and as a result, the connecting pin 5 is locked as shown in FIG. The stopper member 7 and the lower edge of the connecting hole 4a are clamped from above and below and locked.

When the articulator 2 connected to the connecting piece 4 in this way is removed, the releasing mechanism 6 of the connecting means 7 is operated to move the locking member 7 against the pulling force of the spring 12. The locking member 7 engaged in the locking groove 5a of the connecting pin 5 can then come out of the locking groove 5a, so that this state is maintained and the articulator 2 is held. If the articulator 2 is separated from the connecting piece 4, the articulator 2 can be easily removed. At this time, even if the articulator 2 is released, the locking claw 9a of the hook member 9 is retained by the opening edge 8a of the hole 8 as shown in FIG. The articulator 2 will not accidentally fall off and fall.

[0029]

As described above, according to the articulator mounting structure of the first aspect, the articulator can be attached / detached to / from the main body of the human head model with one touch. That is, when the articulator and the connecting portion of the main body are faced to each other and the connecting pin of the articulator is inserted into the connecting hole, the connecting means holds the connecting pin and locks it. Further, at this time, since the hook member is inserted into the hole, the articulator is aligned with the connecting portion of the main body and can be firmly connected with one touch.

When the articulator is to be removed from the connecting portion of the main body supporting portion, operating the operating portion of the decoupling mechanism provided in the connecting means releases the interlocking of the connecting pin. You can remove it as it is. In addition, at this time, even if the articulator is released from the hand, the hook member of the articulator is hooked on the lower edge of the hole of the main body, so that accidental drop and drop can be prevented.

Further, according to the articulator mounting structure of claim 2, since the entire articulator attached to the main body is exposed only by rotating the face head backward, the articulator can be replaced, This is convenient because it is not necessary to remove the mask member attached to the head of the face when replacing the jaw model attached to the device. According to the articulator mounting structure of claims 3, 6, and 7, since the head of the connecting pin has a sharp tip, the locking member that applies the elastic force to bring the connecting hole into the semi-closed state is pushed back. The connecting member can be easily inserted into the connecting hole, and after the connecting pin is inserted into the connecting hole, the locking member is urged by the elastic force in the direction of closing the connecting hole and enters the connecting groove of the connecting pin. In cooperation with the connecting hole, the connecting pin can be pinched and fixed.

Further, when releasing the connection of the connecting pin, the pinching of the connecting pin is released and the connection is released by operating the release mechanism provided in the locking member. Therefore, the release operation is easy. It can be carried out. According to the articulator mounting structure of claim 4, the engaging claws of the hook member are hooked on the side of the opening edge of the punched hole away from the connecting pin, so that the interlocking can be performed temporarily and the disengagement can be performed by engaging the bite. The device can be prevented from falling off, and the hook member serves as a position means at the time of connection, so that the articulator and the main body can be closely aligned and connected without creating a gap.

According to the articulator mounting structure of the fifth aspect, the connected state by the connecting pin, the connecting hole and the locking member can be easily released by operating the operation lever or the operation button of the connection releasing mechanism. According to the human head model provided with the articulator mounting structure according to claim 8, the articulator can be attached and detached by one-touch, and further, the articulator can be prevented from falling and dropping when detaching, and further, the human body The entire articulator can be easily exposed from the head model, and the articulator can be easily replaced.
