As shown in FIG. 4, the hinge parts 5 and 7 join the first main body part 2 and the second main body part 3 so as to be rotatable within a range of about 0 degrees to about 180 degrees. . As shown in FIG. 2, the hinge portion 5 has a receiving groove 10, and the hinge portion 7 has a latch 11. The receiving groove 10 and the latch 11 form a latch structure, and the tip of the latch 11 is The whole is fixed at a predetermined angle by entering the receiving groove 10 and restricting the relative movement between the first main body 2 and the second main body 3.

  The relationship between the latch 11 and the receiving groove 10 as shown by the solid line in FIG. 4 is shown in FIGS. 6 (a) and 6 (b). This is a case where the first main body 2 is intended to be fixed to the second main body 3 at an angle of 90 degrees. Note that the second main body 3 around the latch 11 is omitted because it is complicated. As shown in FIG. 6, the receiving groove 10 is provided with five receiving grooves 10 a to 10 e, and the first main body 2 and the second main body 3 are respectively connected to the receiving groove 10 a by 0 degrees. 10b is fixed at 90 degrees, the receiving groove 10c is fixed at 120 degrees, the receiving groove 10d is fixed at 150 degrees, and the receiving groove 10e is fixed at 180 degrees.

  Therefore, the state shown by the solid line in FIG. 4 is the case where the tip of the latch 11 is in the receiving groove 10b as shown in FIG. 6B. 1 is a case where the tip of the latch 11 is in the receiving groove 10e, and the state of FIG. 2 is a case where the tip of the latch 11 is in the receiving groove 10a.

  As shown in FIG. 2 (b), the latch 11 is partially exposed on the surface of the second main body 3, and a plurality of grooves for preventing slipping are provided on this surface so that a finger can be hung. It has become. 6A, the tip of the latch 11 is retracted from the receiving groove 10 by a finger (not shown), and in this state, the first main body 2 and the second main body 3 have a mutual angle. It freely rotates in the range of about 0 degrees to about 180 degrees. The latch 11 is pressurized by a coil spring. When the finger is released, the latch 11 moves in the direction indicated by the arrow, the tip enters the receiving groove 10b, and the state shown in FIG. The mutual angle of the second main body 3 is fixed.

  The container holding part 6 is provided to hold a chemical container 12 containing a liquid chemical as shown in FIGS. 7A and 7B, and is a male screw for mounting a chemical container cap. The part 14 is held.

The protruding portion 8 protrudes from the second main body portion 3 at a substantially right angle, and the tip of the protruding portion 8 is R2.5- It is a semi-cylindrical surface of about R5. The groove 9 is used to store a rubber band when the protruding portion 8 is fixed with a tissue paper or cotton cloth.

  In addition, although it does not specifically limit about a material, A metal and a synthetic resin can be utilized. Especially for mass production, if synthetic resin is manufactured by injection molding, it can be produced at low cost.

(how to use)
Describe how to use. The initial state is a folded state as shown in FIG. In this state, the positional relationship between the first main body portion 2 and the second main body portion 3 is fixed at 0 degrees due to the latch structure of the receiving groove 10 and the latch 11. Do not open in a bag.

  When used, the latch 11 exposed on the surface of the second main body 3 is slid to the container holding part 6 side with a finger and retracted from the receiving groove 10a to release the fixed state. Then, a hinge will be in a movable state and the 1st main-body part 2 and the 2nd main-body part 3 can be opened. When opened, the latch 11 is inserted into one of the receiving grooves 10 at a predetermined angle and fixed.

  In this embodiment, as shown in FIG. 4, four angles of 90 degrees, 120 degrees, 150 degrees, and 180 degrees can be selected during use. This is due to the positions of the receiving grooves 10b to 10e shown in FIGS. 6A and 6B, and may be at other angles depending on how the receiving grooves 10 are provided.

  When using it as a grandchild's hand, after opening the 1st main-body part 2 and the 2nd main-body part 3 and fixing to a predetermined angle, an arbitrary part, such as the 2nd main-body part 3, is grasped by hand, and the pruritus part 4 is Use it in contact with the part you want to scratch, such as the back.

  The pruritus part 4 has a triple structure as described above. Since the skin is soft and elastic, not only the upper protrusion 4c shown in FIG. 5 but also the lower protrusion 4b contacts the skin even when pressed with a weak force. For this reason, even if itching is not resolved and the grandchild's hand 1 is brought into contact with the skin with a stronger force, only the tip of the upper protrusion 4c does not penetrate deeply into the skin by the lower protrusion 4b. An excessive force is prevented from being applied to the upper protrusion 4c having the tip formed with a smaller radius.

  Therefore, the lower protrusion 4b prevents the skin from being damaged by the upper protrusion 4c. When itching is difficult to remove as seen with the hands of conventional grandchildren, it is possible to avoid rubbing with strong force and damaging the skin. It is important to take care not to damage the elderly because the skin is weak in the elderly and easily damaged, and in the elderly, the wound is difficult to heal. Further, the presence of the upper protrusion 4c can give an appropriate stimulus to the skin even if it is a weak force of an elderly person whose muscle strength has decreased, and itching can be surely eliminated.

  The convex spherical surface 4a has an effect that when the pruritus portion 4 moves on the surface of the skin, the force applied to the skin gently increases and decreases, so that it is difficult to catch and the skin is not damaged. Further, if the lower protrusion 4b and the upper protrusion 4c are arranged on a plane, when the pruritus part 4 and the skin come into contact with each other at an angle, the protrusions at the end may come into contact with each other and force may be concentrated to damage the skin. Although it is conceivable, the lower protrusion 4b and the upper protrusion 4c are arranged on the convex spherical surface 4a, so that even if the pruritus part 4 and the skin are tilted and in contact with each other, the end part may hit one side and damage the skin. There is no. As described above, the pruritus part 4 has a triple structure, so that itching can be easily eliminated without damaging the skin.

  As described above, in the present embodiment, by operating the latch 11 and selecting the receiving groove 10, an easy-to-use angle can be selected and used from the four angles. When the angle is 180 degrees, the entire length is about 600 [mm]. Therefore, even a person whose range of movement of a joint such as a shoulder becomes narrow due to aging can scratch the lower part of the back and the waist. When the angle is 90 degrees, the portion below the shoulder is only the first main body 2 and the length is about 300 [mm], but the upper part of the back can be scratched sufficiently.

  In addition, for a person whose joint movable range is further narrowed due to aging, the arm is difficult to lift, so when the angle between the first main body 2 and the second main body 3 is 180 degrees, the back may be scratched. Although it may be difficult or painful, if you select an angle such as 150 degrees, 120 degrees, or 90 degrees, for example, you can scratch your back even if your arms are only raised up to the chest. The pain of raising it greatly is reduced.

  Further, it has been found that there is another effect particularly when the angle between the first main body portion 2 and the second main body portion 3 is 90 ° to 150 ° and fixed. In the conventional grandchild's hand in which the main body is configured in a straight line, the grandchild's hand is moved up and down to scratch the skin. However, when the angle is set to 90 ° to 150 °, the second main body 3 is attached to the body. By pulling in the forward direction, the itching part 4 of the first main body part 2 can be pressed in the forward direction of the body perpendicularly to the skin surface of the back.

  If the skin is itchy, itching may be eliminated by simply pressing the skin without rubbing it. In this case, there is no damage to the skin. Further, the back massage can be performed by performing a reciprocating motion or a circumferential motion in the horizontal direction with respect to the skin without rubbing while maintaining the positional relationship between the skin and the pruritus portion 4. In this case, the skin is not damaged. Furthermore, by simply pressing, the back muscles can be acupressured by themselves. When the angle formed between the first main body 2 and the second main body 3 is 90 degrees to 150 degrees, the force is easily applied, and thus the above effects are obtained.

(Usage method 1 as chemical applicator)
The grandchild's hand 1 according to the present embodiment can be used for scratching an itchy part such as the back, and for applying medicine to the back while holding a chemical container by utilizing the portability and angle described above. it can. A usage method in this case will be described.

  FIGS. 7A and 7B show the chemical container 12 assumed in this embodiment. Here, a liquid type external analgesic / anti-inflammatory agent that can be applied directly to the skin from a container or a medicine sold for insect bite is used.

  The chemical container 12 is made of a material such as polypropylene (PP), and is provided with a male thread portion 14 for attaching a cap (not shown) integrally on the upper portion, and a sponge-like application surface 13 made of another member at the upper end. There is. There is a valve (not shown) inside the application surface 13, and the valve opens when the application surface is pressed against the skin. At this time, the container is tilted so that the valve is below the liquid level of the chemical inside the container. In some cases, the drug reaches the application surface and can be applied to the skin.

  FIG. 7 (a) is a type in which the male screw portion and the application surface are provided so as to be substantially coaxial with the bottom surface of the container, and FIG. 7 (b) is easy even if the arm is not raised so much when applying to the shoulder or the like. This is a type in which the male screw portion and the axis of the application surface are inclined with respect to the axis of the bottom surface of the container.

  As shown in FIGS. 1 to 3, a part of the fixing member 6 b is exposed on the surface of the second main body portion 3, and a plurality of grooves for preventing slipping are provided on this surface so that a finger can be hung. It has become. A part of the hole 6a retreats into the hole 6a. Since the fixing member 6b is urged toward the center of the hole 6a by the coil spring 6c, a force is applied in the direction of the hinge portion 7 with a finger to retract the hole 6a, and the male screw portion 14 of the chemical container 12 is moved to the hole 6a. Insert. When the finger is released, the male screw portion 14 is fixed in the hole 6a by the fixing member 6b, and the chemical container 12 is held, and the state shown in FIG. 8 is obtained.

  When used as a liquid-type chemical applicator, the first main body 2 and the second main body 3 are opened and fixed at a predetermined angle, and then the container holding portion of the second main body 3 as described above. 6, the medicine container 12 is held, an arbitrary part such as the first main body 2 is grasped by hand, and the application surface 13 of the medicine container 12 is brought into contact with a site to be applied such as the back.

  As in the case of use for scratching the back, by operating the latch 11 and selecting the receiving groove 10, an easy-to-use angle can be selected and used from the four angles. When the angle is set to 180 degrees, even a person whose joint movable range such as a shoulder becomes narrow due to aging can apply the medicine to the lower part of the back and the waist. For a person whose range of movement of the joint is further narrowed due to aging or the like, the medicine can be applied to the back by selecting an angle such as 150 degrees, 120 degrees, or 90 degrees.

  In addition, since the place where the chemical container 12 is held is the male screw portion 14 for attaching the cap in the vicinity of the application surface 13, the movement is stable even when applied to the back where visual confirmation is not possible. The operation to apply the becomes easy. In the case where the medicine container 12 is held at the body or bottom, the holding place is away from the application surface 13 that receives the force from the skin during application, so that the muscle strength is particularly low or the handling is not familiar. In such a case, a movement such that the medicine container 12 falls over the skin is likely to occur, and skill is required for the operation. In this embodiment, since it hold | maintains in the vicinity of the application | coating surface 13, it can be set as a coating thing without such a thing.

  Moreover, since the place to hold | maintain was made into the external thread part 14, since the 2nd main-body part 3 can be close | similar to a back and parallel at the time of application | coating, it can be made easy to handle. In the case where the body portion or the bottom portion of the chemical container 12 is held at a right angle to the second main body portion 3, the second main body portion 3 is parallel to the back due to the influence of the vertical dimension of the chemical container 12. It becomes difficult to maintain and it becomes difficult to operate sensuously. As a result, the chemical container does not become perpendicular to the back, and depending on the degree, the application surface 13 may come into contact with one another and may feel uncomfortable.

  Further, by using the male screw portion 14 as the holding place, use a container of a type in which the axis of the male screw portion and the application surface is inclined with respect to the axis of the container bottom surface as shown in FIG. There is an advantage that can be.

  In general, clamping and fixing the male screw portion is avoided because the screw thread is crushed and a fastening failure with the female screw occurs. However, in a container such as the chemical container 12, the male screw part is formed by injection molding a synthetic resin into a mold, and the tip of the screw thread has a convex R shape, so that a metal screw It is not as sharp as it is, and it is hard to collapse. Experiments with the container holder 6 of the present embodiment revealed that the thread of the chemical container 12 does not suffer from inconveniences such as deformation and crushing.

(Usage method 2 as a chemical applicator)
The grandchild's hand 1 of the present embodiment can apply an ointment-type medicine provided in a tube or bottle in addition to a liquid medicine. As shown in FIG. 9, the protruding portion 8 provided on one end side of the second main body 3 is covered with a fiber sheet member such as tissue paper or cotton cloth, and fastened with a rubber band or rubber band from above the groove 9 and does not move. Like that. As shown in FIG. 9, an ointment or gel-like chemical is applied to a portion corresponding to the outside of the protruding portion 8 so as to be applied to the affected area.

  When used as an ointment type chemical applicator, the first main body 2 and the second main body 3 are first opened and fixed at a predetermined angle, as in the case of liquid medicine. After that, an ointment-type chemical was applied to the tissue paper or the like fixed to the protruding portion 8 of the second main body portion 3 as described above, and an arbitrary part of the first main body portion 2 or the like was applied by hand. Use with the part in contact with the part you want to apply, such as the back.

  Tissue paper and cotton can be easily replaced with new ones and are hygienic. In addition, since it can be easily exchanged, it can be used without resistance when renting to others or sharing with others. In this case, as in the case of using it for scratching an itchy part such as the back, an angle that can be most easily used can be selected from predetermined angles.

(Modification)
Note that the present invention is not limited to the above-described embodiments and modifications, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.

  In the embodiment, the first main body 2 and the second main body 3 are used. However, an integrated main body may be used. In this case, it is not possible to fold or select an angle at the time of use, but if the total length is shortened, portability is not sacrificed, and there are times when it is sufficient for small people. In this case, the main body may be bent or bent at a predetermined angle.

  Even when it is integrated, it can be used to apply the medicine container to the back while holding the chemical container. The effect that a container of a type in which the axis of the surface is inclined with respect to the axis of the bottom surface of the container can be used is the same.

  In the embodiment, the container holding unit 6 holds the container by the hole 6a and the fixing member 6b so as to be compatible with products of various pharmaceutical companies. However, when the product is limited, the inner periphery of the hole 6a is used. In addition, a female screw corresponding to the male screw of the container may be formed, and the male screw part 14 of the chemical container 12 may be screwed and held.

  In the embodiment, the container holding portion 6 is provided with the hole 6a. However, as shown in FIG. 10, instead of the hole 6a, a notch is provided and the male screw portion 14 of the chemical container 12 is inserted. You may make it hold | maintain. Alternatively, the male screw portion 14 may be inserted and held by a spring force with a structure like a so-called clothespin.

Further, the fixing member 6b is pressed by the coil spring, but another elastic member may be used. Alternatively, the elastic member is eliminated and the second threaded portion 14 of the chemical container 12 is inserted and then the second main body portion 3 is inserted. The fixing member 6b may be fixed and used with a screw provided in.
In the embodiment, four angles can be selected at the time of use, but only two angles such as 180 degrees and 90 degrees may be used. In this case, the structure of the hinge part can be simplified.

  Further, the fiber sheet member is fastened with a rubber band or the like, but as shown in FIG. 11, the protruding portion 8 is on one end side of the second main body portion 3 (the other end side when viewed from the grandchild's hand 1 as a whole). If the fiber sheet member is folded and moved in the direction of the hinge portion 7 as indicated by the arrow, it is sandwiched between the protruding portion 8 and the second main body portion 3 and fixed. The rubber band can be made unnecessary. As the structure for fixing the protruding portion 8, a structure such as a click by a notch (V groove) and a leaf spring or other known structures can be used.
