Further, components and members not directly related to the present invention will be omitted.

(1) Embodiment 1
The backscratcher with the drug application function includes a handle 1, a scratch claw 2, a leaf spring member 3, a restrained portion 4, a seat 5, and a locking means 6 (FIGS. 1 to 6).
The handle 1 is a rod-shaped body for the backscratcher, and a scratching claw 2 is provided at one end portion 17. The handle 1 has a length that allows the user to hold the other end 161 near which the operation unit 69 is located and direct the scratch claw 2 downward near the waist from above the shoulder to reach the itchy place on the back. be. The handle 1 here has a rectangular cross section as shown in FIG. 3, and one end 17 side is enlarged like a disk in a plan view.

The scratching claw 2 is a pin-shaped body in which one end portion 17 of the handle 1 is greatly expanded in the shape of a disk in a plan view from a rod shape having a rectangular cross section, and is erected and fixed on the inner surface 1b of the disk-shaped portion 17. A plurality of (here, four) scratching claws 2 are erected along the peripheral edge of the disc-shaped portion 17, and the hands of the grandchild who can scratch the back and other places that cannot be reached are used. A plurality of pin-shaped scratching claws 2 stand up on the disc-shaped portion 17 which is the one end portion 17 of the handle 1 so as to surround the receiving seat 5. In this embodiment, a metal pin is erected and fixed to the disk-shaped portion 17 of the wooden handle 1. For example, a pin-shaped scratch made of a bamboo skewer or the like in a hole provided in the disk-shaped portion 17 of the wooden handle 1. The claw 2 may be pierced and the scratch claw 2 and the handle 1 may be adhered and fixed. Further, a resin molded product in which the scratch claw 2 is thickened to be closer to the shape of a hand integrated with the handle 1 may be used.

The leaf spring member 3 is formed so that the base end portion 31 is fixed to the inner surface 1b near one end 171 of the handle 1 and the tip end portion 32 bends toward one end 171 of the handle 1 and separates from the handle 1. It is a part (Fig. 2). The leaf spring member 3 has the property of deforming when a force is applied to this molded shape and returning to the original shape when the force is removed.
This embodiment is a leaf spring member 3 as shown in FIG. 4 (a), which uses one side portion of a so-called snap-on hair clip. It is a leaf spring member 3 in which the tip portions of a pair of strip plates extending in parallel from the base end portion 31 are forcibly brought together and the brought-up portions are fixed by a stopper 34. Reference numeral 30 is a perforated portion formed by fixing the stopper 34. The leaf spring member 3 is fixed to the inner surface 1b of the handle 1 so that the longitudinal direction from the base end portion 31 toward the tip end portion 32 is aligned with the longitudinal direction from the other end portion 16 of the handle 1 toward the one end portion 17.
Specifically, the base end portion 31 of the leaf spring member 3 is fixed to the inner surface 1b of the handle 1 with a screw V, and the tip end portion 32 rises curvedly from the inner surface 1b of the handle 1 toward one end 171 as shown in FIG. Leave. The outer surface 33a of the intermediate plate portion 33 has an inverted C-shaped cross section as shown in FIG. 4 (b) due to the fixing of the stopper 34. Therefore, unlike the case where two intermediate plate portions 33 are simply arranged horizontally, there is a large force to apply a force from above to the tip portion 32 near the stopper 34 in FIG. 4 (a) to deform it. On the other hand, when the back surface 33b of the leaf spring member 3 related to the tip portion 32 approaches the inner surface 1b of the handle 1 from the distance h1 to the distance h2 by applying a force as shown in FIGS. It becomes horizontal and requires less force. In the present invention, the surface of the handle 1 on the side where the scratch claw 2 stands up is referred to as the inner surface 1b of the handle 1, and the surface of the leaf spring member 3 facing the inner surface 1b of the handle 1 is referred to as the back surface 3b.

The restrained portion 4 is a portion located at the tip end portion 32 of the leaf spring member 3 that can be moved toward the inner surface 1b side of the facing handle 1 against the spring elasticity of the leaf spring member 3. The restrained portion 4 may be carried on the portion of the tip portion 32 facing the inner surface 1b of the handle 1, or may be a separate part integrated with the back surface 32b of the tip portion 32.
Here, the restrained portion 4, which is a separate part of a substantially rectangular body formed of a permanent magnet on the back surface 3b side of the leaf spring member of the tip portion 32, is coupled and integrated with the tip portion 32 with a binder j as shown in FIG. .. The permanent magnet of the restrained portion 4 is preferably a rare earth magnet or a rare earth iron magnet containing rare earths such as Nd and Sm having a strong magnetic force, and these permanent magnets are also adopted in this embodiment.

The receiving seat 5 is a receiving portion for an ointment provided with a receiving surface 51 for attaching the ointment M on the outer surface 3a side of the tip end portion of the leaf spring member 3. Here, the ointment M is a drug to be applied to the skin of the affected area, and includes ointments, creams, gels and the like. The receiving seat 5 may be formed by processing the tip portion 32 of the leaf spring member 3, but in the present embodiment, as shown in FIG. 3, a separate disc-shaped seat having the receiving surface 51 on the outer surface 3a of the tip portion 32. 5 is fixed and integrated with the tip portion 32. In the state of FIG. 2 in which no external force is applied to the leaf spring member 3, the receiving seat 5 is fixed to the leaf spring member tip portion 32 with the flat receiving surface 51 facing downward and substantially horizontal.

The locking means 6 holds the restrained portion 4 at the tip end portion 32 of the leaf spring member 3 which has been moved toward the inner surface 1b side of the facing handle 1 against the spring elasticity of the leaf spring member 3. It is a locking device that keeps the restraint and keeps it as it is.
The present embodiment is a locking means 6 including a shaft member 61, a bearing 62, a coil spring 63, and a tip 64. On the outer surface 1a side of the handle 1 opposite to the surface on which the scratching claw 2 is located, the shaft member 61 of the locking means 6 extends along the handle 1 from the other end 16 to the one end 17, and one end. The massive chip 64 of the ferromagnetic material is fixed to the tip region 611 of the shaft member 61 on the portion 17 side. The chip 64 employs a ferromagnet that is strongly attracted to a magnet, such as iron, nickel, cobalt and its alloys.
Bearings serving as the insertion holding portion 62 of the shaft member 61 are provided at two locations near one end 17 from the point where the leaf spring member 3 is fixed to the handle 1 to the point where the disc-shaped portion 17 is formed, as shown in FIG. Further, it is provided at one place near the other end 161 near the operation unit 69. These are provided on the outer surface 1a side of the handle 1, and the shaft member 61 is inserted into the shaft hole of each bearing 62 and is supported by the bearing 62 so as to be movable back and forth in the left-right direction of the paper surface of FIG. As shown in FIG. 1, a coil spring 63 is interposed between the two bearings 62 provided near the one end portion 17, and the flange 619 fixed to the shaft member 61 is moved to the other end 161 side by the spring elastic force of the coil spring 63. The shaft member 3 is held so as to be pressed against the bearing 62 to be arranged. Under this state, the ferromagnetic chip 64 provided at the tip of the shaft member 61 abuts on the central outer surface 1a of the disc-shaped portion 17, and between the operating portion 69 and the bearing 62 provided near the other end 161. In addition, a margin 612 that allows the shaft member 61 to advance to the left in FIG. 1 is secured.

The operation unit 69 is provided on the other end 161 side of the handle 1 and is a part of the locking means 6 for releasing the restraint maintenance of the restrained portion 4. The operation unit 69 of the present embodiment has a shaft diameter of the end portion of the shaft member 61 arranged near the other end portion 16 so that the other end portion 16 of the handle 1 can be easily touched and further operated. Form thicker than.

Thus, under the state of FIG. 2 in which no external force is applied to the leaf spring member 3, when an external force is applied upward to the lower surface of the outer surface 3a of the leaf spring member tip portion 32, the leaf spring member 3 is shown in FIG. The state changes from the state to the state shown in FIG. This external force is a force that moves the restrained portion 4 integrated with the leaf spring member tip portion 32 to a close distance to the tip 64. The restrained portion 4 and the chip 64 shown in FIG. 1 placed on the central outer surface 1a of the disc-shaped portion 17 are in close proximity to each other, and the inner surface 1b on one end side of the handle 1 with which the restrained portion 4 faces is attracted by magnetic force. When it comes into contact with (or is close to) the surface, it is stopped and maintained even if the external force is removed. As described above, the leaf spring member 3 in the state of FIG. 5 does not require strong magnetic force attraction, and the restrained portion 4 can be brought into contact with the inner surface 1b on one end side of the facing handle 1 to be restrained and maintained. Under the restrained state, the tip 21 of the four scratching claws 2 surrounding the four sides of the seat 5 protrudes from the receiving surface 51 by the amount of the reference numeral α in FIG. It will be ready to be used as a backscratcher.

On the other hand, from the state of FIG. 1, the magnetic force attraction between the restrained portion 4 and the chip 64 is weakened by advancing the chip 64 by the operation unit 69 and separating it from the restrained portion 4. This weakening of the magnetic force attracting force releases the restraint maintenance, and the leaf spring member 3 is restored by the elastic restoring force. As shown in FIG. 2, the receiving surface 51 is in a state of protruding from the tip 21 of the scratch claw 2 by the amount of the reference numeral β.
Specifically, the finger of the hand holding the handle 1 pushes the operation portion 69 to the left in FIG. 1 against the elasticity of the coil spring 63. Then, the tip 64 placed on the central outer surface 1a of the disc-shaped portion 17 advances to one end 171 of the handle 1 as shown in FIG. 2 via the shaft member 61, and the tip 64 and the restrained portion 4 are combined with each other. The distance is far. When they are separated, the magnetic attraction between them weakens. With the release of this restraint maintenance, the leaf spring member 3 returns from the state of FIG. 5 to the state of FIG. 4 due to the elastic restoring force, and in FIG. 2, the substantially horizontal receiving surface 51 is the tip 21 of the scratch claw 2. Protruding more than.
Apply an anti-itching agent M to the receiving surface 51 in FIG. 1, then grasp the other end 161 of the handle 1, insert the tip 32 between the underwear and the neck from above the shoulder, and put on the clothes by yourself. You can apply the medicine M to the part of your back that you cannot reach while wearing it.

Here, the collar 619 fixed to the shaft member 61 was pressed against the bearing 62 arranged on the other end 161 side by the elastic force of the coil spring 63, but the collar 619 fixed to the shaft member 61 was pressed to one end 171 by the elastic force of the coil spring 63. It may be pressed against the bearing 62 arranged on the side (see FIG. 9). In such a case, the tip 64 is retracted to the right in FIG. 1 by the operation unit 69 to release the restraint maintenance that weakens the magnetic force attraction.
Further, as described above, the chip 64 of the ferromagnetic material is fixed and the restrained portion 4 is formed of a permanent magnet, but the chip 64 of the permanent magnet is fixed and the restrained portion 4 is formed of a ferromagnetic material. It may be.

Further, the handle 1 is divided into one end side handle portion 1A and the other end side handle portion 1B in the middle of the longitudinal direction thereof, and the other end side handle portion 1B is tiltably connected to the one end side handle portion 1A. It can be a backscratcher with a coating function.
For example, a handle divided into one end side handle portion 1A and the other end side handle portion 1B is connected to the one end side handle portion 1A so that the other end side handle portion 1B can be moved downward by using the bending adjusting portion 19. It is 1. As shown in FIG. 6, the end portion of the one end side handle portion 1A and the end portion of the other end side handle portion 1B are sandwiched and held by a pair of bending adjusting portion plate pieces 191 on the front side of the paper surface and the back side of the paper surface. The one-sided handle portion 1A is fixed to the plate piece 191 while the other end side handle portion 1B is provided with a guide pin 192 protruding from the arcuate hole 1910 provided in the plate piece 191. The guide pin 192 integrated with the other end side handle portion 1B gets over the convex portion 1911 swelling in the hole of the arcuate hole 1910, stops moving from the chain line position to the solid line position, and stops moving from the chain line position to the solid line position, and is on the other end side with respect to the one end side handle portion 1A. The lower movement angle of the handle 1B can be switched from the chain line position in FIG. 6 to the solid line position. The shaft member 61 is also divided into two so that the angle of the handle portion 1B on the other end side can be changed with respect to the handle portion 1A on one end side, and both are connected by a flexible rubber connecting member 614 or the like.

In addition, the present embodiment includes a cap 8 and an auxiliary tool 9 for scratching nails.
The cap 8 is a covered tubular body in which the top surface 811 of the lid portion 81 is recessed or swells toward the center of the lid, and has the shape of a bottle lid as shown in FIG. It is a cap 8 used as needed, and the lid portion 81 covers the receiving surface 51 of the seat 5, and the side peripheral portion 82 is attached to the receiving peripheral side surface 52 and is detachably attached to the receiving seat 5. Be done.
The scratching tool 9 is a sack-shaped product having a tubular portion 92 having a tubular inner diameter that is equal to or larger than the shaft diameter of the scratching claw 2. It is an auxiliary tool 9 for scratching claws that covers the tip of the scratching claw 2 from the tube mouth side and is detachably attached to the scratching claw 2 as needed. Here, small items 93 such as a foamed resin material (or pig hair aggregate) having lower thermal conductivity than metals are fixed and integrated on the outer surface of the bottom portion 91 of the vertically long bottomed cylindrical body as shown in FIG. It is referred to as a scratching aid 9 that has been made.

Next, one usage of the backscratcher with pomalidomide application function will be described.
First, the normal locking means 6 is in the state shown in FIG. The flange 619 abuts on the bearing 62 and is locked by the urging of the coil spring 63, and the operating portion 69 arranged at the right end of the shaft member 61 is on the right side of the right end bearing 62 in FIG. In FIG. 1, the chip 64 arranged at the left end of the shaft member 61 abuts on the substantially central outer surface 1a of the disk-shaped portion 17.
Then, when the leaf spring member 3 is located at a position away from the inner surface 1b of the handle 1 in the state as shown in FIG. 2 in which no external force is applied to the leaf spring member 3, the spring elasticity of the leaf spring member 3 is resisted. Then, an external force by hand is applied upward to the receiving surface 51 from below the paper surface, and the restrained portion 4 is applied to the inner surface 1b of the handle 1 as shown in FIG. After that, the magnetic force attraction between the restrained portion 4 and the chip 64 keeps the restrained portion 4 restrained and maintained even if no external force is applied. Under such a state, the scratching claw 2 has its tip 21 protruding from the receiving surface 51 as shown in FIG. 1, and can be used as a backscratcher.

Further, when trying to apply the anti-itching agent M to a predetermined place on the back, the application M is applied to the receiving surface 51 in the state of FIG. Then, holding the other end 161 side of the backscratcher with the application function in the hand, insert the one end 17 side of the handle 1 into the back so that the receiving surface 51 faces the body side from between the underwear and the neck. .. Subsequently, after confirming the itchy portion with the scratch claw 2, the operation portion 69 is manually pushed toward the tip 64 side against the spring elasticity of the coil spring 63. Then, the tip 64 is separated from the restrained portion 4, and the magnetic force attraction with the restrained portion 4 is weakened. As a result, the elastic restoring force of the leaf spring member 3 brings about the state of FIG. The receiving surface 51, which is surrounded by the scratching claw 2 and retracted, pops out and becomes a backscratcher with a desired drug applying function capable of applying the drug M on the receiving surface 51 to the itchy portion.
If the operation unit 69 is stopped to be pushed by hand, the restoring force of the coil spring 63 returns to the original state shown in FIG.

(2) Embodiment 2
This embodiment is a backscratcher with a drug application function as shown in FIGS. 7 and 8. 7 corresponds to FIG. 1 and FIG. 8 corresponds to FIG.
The locking means 6 uses a flexible string-shaped body 65 instead of the shaft member 61 of the first embodiment. The string-shaped body 65 of the locking means 6 having one end 652 attached to the operation portion 69 extends from the other end 16 to the one end 17 of the handle 1 along the outer surface 1a of the handle 1, and further extends the handle 1. The other end portion 651 of the string-like body 65 is attached to the restrained portion 4 through the through hole 10 provided near one end 171 of 1. The through hole 10 is formed substantially in the center of the disc-shaped portion 17.

The insertion holding portion 62 of the string-shaped body 65 corresponding to the bearing 62 of the first embodiment is provided on the outer surface 1a of the handle 1 at two locations, near the disc-shaped portion 17 and near the other end 161 as shown in FIG. The string-shaped body 65 is inserted into the holes of both insertion holding portions 62 and is held so as to be able to move forward and backward. By pulling the string-shaped body 65 from one end 17 to the other end 16 of the handle 1 at the operation portion 69, the restraint at the tip portion 32 is resisted against the spring elasticity of the leaf spring member 3. The portion 4 can be moved toward the inner surface 1b side of the handle 1 facing each other, and the state can be restrained and maintained.
Specifically, a plate piece-shaped hook portion 66 having a U-shaped groove 660 shown in FIG. 7 is provided near the other end 161. The string-shaped body 65, which is moved by pulling the restrained portion 4 at the tip portion 32 toward the inner surface 1b side of the facing handle 1 against the spring elasticity of the leaf spring member 3, exceeds the hook portion 66. A stopper piece 659 is attached and fixed at the point. While maintaining the state where the stopper piece 659 is arranged on the other end 161 side of the handle 1 with respect to the hook portion 66, the string-shaped body 65 is inserted into the U-shaped groove 660 from the groove opening to restore the leaf spring member 3. Even if a force is applied, the stopper piece 659 is set to be locked to the hooking portion 66 as shown in FIG. 7 (b). In this way, the state as shown in FIG. 7 in which the restrained portion 4 is moved toward the inner surface 1b side of the facing handle 1 is restrained and maintained.

On the other hand, when the tip portion 32 is separated from the handle 1 by the elastic restoring force of the leaf spring member 3 due to the release of the restraint maintenance, the receiving surface 51 protrudes outward from the tip 21 of the scratch claw 2 in FIG. become. The restraint maintenance can be released by, for example, lifting the operation unit 69 of FIG. 7 upward and removing the stopper piece 659 from the U-shaped groove 660. When the stopper piece 659 is removed from the U-shaped groove 660, the leaf spring member 3 returns to the state shown in FIG. 8 by the elastic restoring force. The stopper piece 659 detached from the U-shaped groove 660 moves closer to the insertion holding portion 62 as the string-shaped body 65 moves to the left side in FIG.
By the way, when moving from the state of FIG. 8 to the state of FIG. 7, the operation portion 69 is used, and the stopper piece 659 is simply locked to the hook portion 66 against the spring elasticity of the leaf spring member 3. .. In this embodiment, only the spring elasticity of the leaf spring member 3 is used to enable the shape change of FIGS. 7 and 8. It is not enough to form the chip 64 and the restrained portion 4 in the first embodiment with a ferromagnetic material or a permanent magnet. The coil spring 63 is also unnecessary.
The other configurations are the same as those in the first embodiment, and the description thereof will be omitted. The same reference numerals as those in the first embodiment indicate the same or equivalent portions.

(3) Embodiment 3
This embodiment is a backscratcher with a drug application function as shown in FIGS. 9 and 10. 9 corresponds to FIG. 2 and FIG. 10 corresponds to FIG.
As shown in the figure, the restrained portion 4 of the inverted L-shaped hook 41 is fixed to the back surface 3b side of the spring member of the tip portion 32. Here, although the hook 41 is fixed to the receiving seat 5, it is considered that the hook 41 is fixed to the tip portion 32 of the present invention.
Then, the same bearing 62 as in the first embodiment is provided at the same position on the outer surface 1a of the handle 1, and is inserted into each bearing 62 on the outer surface 1a side of the handle 1 which is opposite to the surface where the scratching claw 2 is located. The bearing 61 extends along the handle 1 from the other end 16 to the one end 17. Further, the L-shaped locking tool 68 as shown in FIG. 9 is fixed to the tip region 611 of the shaft member 61 on the one end 17 side in place of the tip 64. Further, a coil spring 63 similar to that in the first embodiment is inserted between the two bearings 62 provided near the one end portion 17, but the flange 619 fixed to the shaft member 61 is inserted into the one end portion by the elastic force of the coil spring 63. It is pressed against the bearing 62 arranged on the 17 side. Under this state, the locking tool 68 provided in the tip region 611 of the shaft member 61 is arranged substantially in the center of the disc-shaped portion 17. A through hole 10 larger than the through hole 10 of the second embodiment is provided in the center.

In this way, when the leaf spring member tip portion 32 is located at a position away from the inner surface 1b of the handle 1 in the state as shown in FIG. 9 in which no external force is applied to the leaf spring member 3, the leaf spring member Against the spring elasticity of 3, the external force is applied upward to the receiving surface 51 from below the paper surface of FIG. Then, the hook 41 hits the inclined portion of the lower surface of the locking tool 68 as shown by the chain line, and the locking tool 68 moves the shaft member 61 to the right of FIG. 9 against the elasticity of the coil spring 63, and finally. As shown in FIG. 10, the hook 41 is placed on the locking tool 68 and is in the locked state. In this state, the restrained portion 4 is maintained in a restrained state even if no external force is applied. The restrained portion 4 as the hook 41 approaches (or abuts) the inner surface 1b on the 171 side at one end of the handle 1 by proceeding from the initial FIG. 9 to FIG. Under such a state, the scratching claw 2 has its tip 21 protruding from the receiving surface 51 as shown in FIG. 10, and can be used as a backscratcher.
The user may pull the operation unit 69 to the right in order to move the shaft member 61 to the right in FIG. 9 described above. By the way, after the hook 41 is placed on the locking tool 68 in the locked state, if the external force due to the pulling to the right of the operation unit 69 or the hand is removed, the locking tool 68 is shown by the restoring force of the coil spring 63. It returns to the original state shown in 9.

Further, when it is desired to apply the anti-itching agent M to a predetermined place on the back, the application M is applied to the receiving surface 51 in the state of FIG. Hold the other end 161 side of the backscratcher with application function in this state, and insert the one end 17 side of the handle 1 into the back so that the receiving surface 51 faces the body side from between the underwear and the neck. To go. Then, after confirming the itchy portion with the scratch claw 2, when the operation portion 69 is pulled to the right in FIG. 10 against the spring elasticity of the coil spring 63, the locking tool 68 moves to the right in the figure. The hook 41 comes off from the locking tool 68, and the elastic restoring force of the leaf spring member 3 brings about the state shown in FIG. The receiving surface 51, which was surrounded by the scratching claw 2 and retracted, pops out and becomes a backscratcher with a drug applying function that can apply the drug M on the receiving surface 51 to the itchy portion.
The other configurations are the same as those in the first embodiment, and the description thereof will be omitted. The same reference numerals as those in the first embodiment indicate the same or equivalent portions.

(4) Effect The backscratcher with the drug application function configured as described above includes the leaf spring member 3, the receiving seat 5, the restrained portion 4, the locking means 6, the scratching claw 2, and the operating portion 69, and the locking means 6 is provided. Therefore, the restrained portion 4 at the tip portion 32 of the leaf spring member, which has been moved toward the inner surface 1b side of the facing handle 1 against the spring elasticity of the leaf spring member 3, can be restrained and maintained in that state. Since the tip 21 of the scratching claw 2 protrudes from the receiving surface 51 in the state of maintaining the restraint, it can be used as a backscratcher (FIGS. 1, 7, and 10). When used as a backscratcher, the seat 5 is retracted more than the scratch claw 2 so it does not get in the way.

In addition, if the state of FIGS. 1, 7, and 10 is maintained and the backscratcher has a medicine application function in which the receiving surface 51 is covered with an anti-itching agent M, the medicine M can be applied to the itchy part of the back by itself. Can be easily applied. Moreover, unlike Patent Document 2, the drug M can be applied to a necessary place without getting dirty even while wearing clothes.
For example, in FIGS. 1 and 7, after applying an anti-itching agent M to the receiving surface 51, grasp the other end 161 side of the handle 1 and hold the tip portion 32 between the underwear and the neck from above the shoulder. To insert. Then, the scratched nail 2 is used to find out where the itch is. In this process, the coating agent M applied to the receiving surface 51 is protected by the scratching claws 2 surrounding the coating agent M, so that the body, underwear, and the like are not unnecessarily soiled.
Next, after confirming the itchy portion with the scratching claw 2, in the case of FIG. 1, the operation portion 69 is pushed toward the one end portion 17 side. In the case of FIG. 7, the stopper piece 659 is removed from the hook using the operation unit 69. Then, the leaf spring member 3 recovers from the state of FIGS. 1 and 7 by the elastic restoring force, and the receiving surface 51 protrudes from the tip 21 of the scratch claw 2 as shown in FIGS. 2 and 8. Then, the ointment M attached to the receiving surface 51 adheres to the skin surface of the back of the itchy portion, and the medicine M can be applied to all the necessary portions by slightly moving the hand holding the other end 161.
Moreover, it is only necessary to apply the drug M to the receiving surface 51 as much as it is used in advance, and unlike Patent Document 1, there is no waste.

In addition, in the leaf spring member 3 used in the present embodiment, the intermediate plate portion 33 has an inverted C shape as shown in FIG. 4 (b) in the operation process of applying the drug M to the skin, and the spring pressure is strong. Therefore, the medicine M can be smoothly applied to the skin surface. On the other hand, in the leaf spring member 3 in the state of FIG. 1 from the upper part of the shoulder to the itching part until the receiving seat 5 with the medicine M is carried, the intermediate plate portion 33 is horizontal and the spring elasticity is as shown in FIG. 5 (b). Is weakened, so that the state shown in FIG. 1 can be maintained even with a small magnetic force attraction. It is a leaf spring member 3 that makes a very reasonable sense for the present invention.

In this way, the backscratcher with the romiplostim application function can smoothly apply the drug M such as anti-itch to the back part that cannot be reached by oneself, which is extremely excellent for people living alone. Further, since the itching place is specified in advance by the scratching nail 2 of the backscratcher and then the receiving surface 51 is projected from the tip 21 of the scratching nail 2, the medicine M can be reliably applied to the itching place.
Moreover, unlike Patent Document 2, the drug M can be easily applied only to the necessary parts of the back while wearing clothes, so it is not necessary to take off the clothes and underwear especially in the cold season, and the drug application is excellent in usability. It is in the hands of a functional grandson.

The change from the state of FIGS. 1 and 7 to the state of FIGS. 2 and 8 does not require a new power source because the elastic restoring force of the leaf spring member 3 is used.
Further, since the operation unit 69 is provided on the other end 161 side of the handle 1, after checking the itchy part such as the back, it is only necessary to slightly move the finger of the hand holding the other end 161 to operate FIGS. 1 and 7. The state of the receiving surface 51 of FIGS. 2 and 8 can be easily changed from the state of.

Further, in the second embodiment, when the other end portion 651 of the string-shaped body 65 is attached to the restrained portion 4, the string-shaped body 65 is moved from one end portion 17 to the other end portion of the handle 1 by the operation portion 69. By pulling in the direction of 16, the restrained portion 4 at the tip portion 32 can be moved toward the inner surface 1b side of the facing handle 1 against the spring elasticity of the leaf spring member 3, and the state can be restrained and maintained. .. Further, if the stopper piece 659 is removed from the hook portion 66, the restraint maintenance is released, the tip portion 32 is separated from the handle 1 by the elastic restoring force of the leaf spring member 3, and the receiving surface 51 is separated from the tip 21 of the scratch claw 2. Can also be projected outward. As in the first embodiment, the restrained portion 4 and the chip 64 are not as good as permanent magnets or ferromagnets. The coil spring 63 is also unnecessary, and the backscratcher with a drug application function can be simplified in configuration and cost can be reduced.

Further, the handle 1 is divided into one end side handle portion 1A and the other end side handle portion 1B in the middle of the longitudinal direction thereof, and the other end side handle portion 1B is tiltably connected to the one end side handle portion 1A. Then, for example, as shown in FIG. 6, one portion of the other end 161 side handle can be refracted so that the shoulder blade or the like on the back can be successfully overcome.
Further, when the right side cap 8 of FIG. 2 in which the top surface 51 is recessed is attached to the receiving seat 5, the coating agent M attached to the top surface 51 can be successfully applied by concentrating it only on the necessary portion of the back. Further, when the left side cap 8 of FIG. 2 in which the top surface 51 swells is attached to the receiving seat 5, the coating agent M attached to the top surface 51 can be smoothly spread on the required portion of the back.
In addition, if the scratching tool 9 shown in FIG. 1 is attached to the scratching nail 2, the height of the scratching tool 9 is added to the scratching nail 2, and the height can be adjusted higher than that of the scratching nail 2. .. Further, since the small item 93 having low thermal conductivity hits the back or the like instead of the scratched nail 2, it is possible to avoid feeling the skin cold when used in winter or the like.
As described above, the backscratcher with the romiplostim application function exerts the various excellent effects described above and is extremely beneficial.
