  The present invention relates to a teaching tool relating to cosmetic trimming, and more particularly to a support structure for fixing a teaching limb model for teaching of cosmetic trimming technology.

  When teaching beauty styling techniques, there are cases where hands-on models and foot models are used to demonstrate massage techniques and techniques for applying manicure to nails, and to perform these trainings. The structure that supports the limb model that has been commonly used in the past has a vacuum suction disk for fixing the support to the table at the bottom of the support and swings within a certain angle at the tip of the support. One connecting rod that can be positioned is provided, a ring with a screw hole is fixed to the connecting rod, and the bolt provided on the bottom of the limb model is fitted into the screw hole, so that the limb model is It has a structure that can be fixed to the support structure. When the limb model is supported by such a support structure, the ring fitted to the connecting rod is easily detached from the connecting rod, so that the limb model is easily detached from the support, while the connecting rod is limited within a limited range. However, it was inconvenient to use because it could not be adjusted.

  A main object of the present invention is to provide a support structure for a limb model that is firmly connected to the limb model and is easy to attach and detach.

  Another object of the present invention is to provide support for a limb model that can be adjusted in height and multi-direction.

In order to achieve the main object, the present invention provides a support structure including a fixing mechanism for fixing the support structure to the table, a base connected to the fixing mechanism, and a joint member for fixing the limb model.
The tip of the base has a pipe shape, and a plurality of radial through holes are arranged in a ring shape on the pipe wall. The diameter of the radial through holes is larger than the thickness of the pipe wall and the radial direction of the pipe wall. A ball that is movable along the base is built in, and an inner spring that elastically expands and contracts in the base axial direction is provided inside the base pipe, and an outer spring is connected to the outer side of the base pipe. A movable ring that is movable in the axial direction and is provided with a convex ring on the inner wall is fitted, and in the state where the outer spring is extended, the convex ring provided on the inner wall of the movable ring Push each ball inward of the pipe wall so that each ball does not protrude from the outer surface of the pipe wall of the base, and there is a ring-shaped concave groove on the outer periphery of the joint member so that the joint member and the base are connected The joint member has a distal end extending outward from the base pipe, a distal end of the joint member is inserted into the base pipe, an inner spring is compressed by the joint member, and a part of each ball is a ring-shaped concave groove. It is the support structure characterized by having fitted in.

  Furthermore, the present invention is characterized in that the axial cross-sectional shape of the ring-shaped concave groove is an arc shape or a trapezoidal shape.

  A screw hole or bolt for connecting to a bolt or screw hole provided at the bottom of the limb model is provided on the distal end side of the joint member. Needless to say, the joint portion and the limb model may be integrally fixed.

  The fixing mechanism may be a “U” -shaped fixing frame with fixing bolts.

  The fixing mechanism and the base may be connected by a flexible metal pipe so that the height and direction of the support structure can be freely adjusted.

  In order to facilitate the insertion of the joint member into the pipe of the base, a movable member having a cup-like opening is provided inside the pipe of the base, and when the joint member and the base are connected, the end side of the joint member is connected to the movable member. The movable member is inserted into a cavity having a cup-shaped opening, and the ring-shaped concave groove is outside the cavity having the cup-shaped opening of the movable member, and the movable member is separated from the base when the joint member is separated from the base. An outer wall of the cup-shaped opening is located inside each of the balls, and pushes each ball to the outside of the pipe wall of the base.

  In the present invention, the support structure is fixed by holding the table with a "U" -shaped fixing frame and tightening the fixing bolt. The front end of the joint member and the bottom of the limb model are fixedly connected by screwed screw holes and bolts.

  The end side of the joint member is inserted into the pipe of the base, a part of each ball provided on the pipe wall of the base is fitted into the ring-shaped concave groove of the joint member, and each ball is formed by the convex ring on the inner wall of the movable ring. The joint member and the base are fixed by being restricted so as not to move outward. At this time, the inner spring provided in the base pipe is compressed by the joint member. By bending a flexible metal pipe, the height and direction of the limb model can be arbitrarily adjusted and positioned. When removing the joint member after use, the movable ring is moved, the convex ring is removed from each ball, the inner spring in the base pipe is restored by elastic force, and the joint member is pushed out. The model can be removed.

  Unlike the prior art, the support structure of the present invention fixes the joint member and the base by fitting the ball into the concave groove, so that the limb model and the support structure can be firmly connected. Also, when removing this, simply pressing the movable block will release the contact between the convex ring and the ball, and the joint member will be pushed out of the base, making it easy to operate and convenient to use. is there. By providing a movable member having a cup-shaped opening in the base, when the joint member is separated from the base, each ball is pushed to the outside of the pipe wall of the base. When connecting, there is no need to move the movable ring, and the joint member may be pushed into the pipe of the base until each ball is fitted into the ring-shaped concave groove, which can be operated quickly and easily. Since the fixing mechanism and the base are connected by a flexible metal pipe, the model can be adjusted to an arbitrary direction and an arbitrary height, and can be positioned freely. Therefore, there is an effect that it becomes more convenient to use the model.

Specific embodiments of the present invention will be described in detail with reference to the drawings.

Example 1
As shown in FIG. 1, the support structure of the present invention includes a “U” -shaped fixing frame (that is, a fixing mechanism) 1, a flexible metal pipe 2, a base 3, and a joint member 4. The fixing bolt 11 provided on the “U” -shaped fixing frame is tightened to fix the entire support structure to the table 6. When the screw hole 41 provided on the distal end side of the joint member 4 is screwed with the screw 51 at the bottom of the limb model 5, the limb model 5 is connected to the support structure. When the limb model 5 is used, the flexible metal pipe 2 is arbitrarily curved as necessary in order to adjust the direction and height of the limb model 5. In order to improve the appearance and durability of the support structure, a plastic flexible pipe may be used instead of the flexible metal pipe 2.

  As shown in FIG. 2, the tip side of the base 3 has a pipe shape, and a movable ring 31 and an outer spring 32 are fitted to the outside of the pipe. Due to the elastic support by the outer spring 32, the movable ring 31 can move up and down along the base axis within a certain range. A convex ring 35 is provided on the inner wall of the movable ring 31. The inner diameter of the convex ring 35 is set slightly larger than the outer diameter of the base 3 so that the movable ring 31 can move up and down smoothly.

  A plurality of radial through holes 38 are arranged in a ring shape on the pipe wall of the base 3, and one ball 34 is installed in each through hole 38. The ball 34 can move in the radial direction in the through hole 38, and a part of the ball 34 protrudes toward the inside and the outside of the pipe wall of the base 3 by a certain size, and penetrates the ball 34. The diameter of the ball 34 is set smaller than the through hole 38 and larger than the plate wall thickness so that the ball 34 does not fall out of the hole 38.

  When the outer spring 32 is in the extended state, the convex ring 35 is on the outside of each ball 34, so that a part of each ball 34 protrudes inward from the inner wall of the pipe of the base 3. A movable member 36 having a cup-shaped opening and an inner spring 33 are arranged in the base 3, and the bottom of the movable member 36 is connected to the tip side of the inner spring 33, and the bottom of the inner spring 33 is the inner side of the base 3. It is connected to the shoulder of the wall.

  In a state where the joint member 4 is connected to the limb model, the joint member 4 is inserted inside the movable member 36 having a cup-shaped opening, and the joint member 4 connected to the limb model 5 by the screw hole 41 is located outside the base 3. Is stretched. Each ball 34 pressed by the convex ring 35 is fitted into a ring-shaped concave groove 42 provided on the outer periphery of the intermediate portion of the joint member 4, so that the joint member 4 is firmly connected to the base 3. At this time, the inner spring 33 is in a compressed state.

  When removing the limb model 5 from the support structure, the joint member 4 is first separated from the base. As shown in FIG. 3, when the movable ring 31 is pushed down by hand, the outer spring 32 is compressed and the convex ring 35 is detached from each ball 34. The compressed inner spring 33 moves upward by an elastic restoring force, pushes up the movable member 36 having a cup-shaped opening shape, and the joint member 4 is pushed out of the base 3. At this time, the cup-shaped opening of the movable member 36 is just inside each ball 34, and each ball 34 is pressed against the outside of the pipe wall of the base 3, so that the movable ring 31 with the convex ring 35 moves upward. To stop doing.

  After separating the joint member 4 from the base 3 in this way, the screw that has fixed the limb model 5 and the joint member 4 is loosened, and the limb model 5 is removed.

  Needless to say, the joint member 4 and the limb model 5 can be integrally processed.

  When attaching the limb model again, after fixing the joint member 4 and the limb model 5, the joint member 4 is pushed into the pipe of the base 3 together with the movable member 36 having a cup-like opening shape, When the concave groove 42 reaches the inside of each ball 34, each ball 34 is pushed from the outside to the inside by the convex ring 35 by the elastic restoring force of the outer spring 32, so that each ball 34 is formed in the ring-shaped concave groove 42. Push it in again and it will be in the state shown in Fig. 2 again.

  In order to allow the joint member 4 to be smoothly pushed out by the inner spring 33, the shape of the ring-shaped concave groove 42 provided on the outer periphery of the joint member 4 in the axial section may be an arc shape or a trapezoidal shape. In order to alleviate the collision between the movable member 36 and the joint member 4, a rubber cushion 37 may be provided on the contact surfaces thereof.

Example 2
As shown in FIGS. 4 and 5, the difference between the second embodiment and the first embodiment is that the movable member 36 located in the base 3 has a cup-shaped opening shape in the first embodiment. Thus, the second embodiment has a block shape.

  The configuration other than the movable member 36 of the second embodiment is almost the same as the configuration of the first embodiment. By adopting such a configuration, there is an advantage that the structure is simple, easy to process, and the manufacturing cost can be reduced. However, before the joint member 4 is inserted, it is necessary to move the movable ring 31 downward by hand to separate the convex ring 35 from each ball.
