Description

[Technical Field]

[0001] The present invention relates to a stimulating device for stimulating the skin, acupressure points, etc. of humans and animals. [Background technology]

[0002] For example, acupressure tools have been proposed as devices for stimulating acupressure points on the human body (see, for example, Patent Document 1). This acupressure tool is composed of a front half made of an elastic member and a rear half to which the front half is attached, with a tapered pressing part at the tip of the front half. A shaft insertion hole is provided at the rear end of the front half, and an acupressure shaft is provided at the front end of the rear half, and the front half is attached to the rear half by inserting the acupressure shaft into the shaft insertion hole in the front half.

[0003] In this acupressure tool, the front and rear halves are attached to each other and integrated, so it can be easily handled by grasping its outer periphery, and the tip of the front half can be pressed against an acupressure point or the like and kept pressed for a long period of time, making it usable as a pressure tool for acupressure points, etc.

[0004] Also proposed is a scalp massager / shoulder tapper that can stimulate the scalp and can also be used as a shoulder tapper (see, for example, Patent Document 2). This scalp massager / shoulder tapper has multiple protrusions on the outer periphery of the bottom of a container with an opening, and the multiple protrusions on the bottom side of the container function as the shoulder tapper. A base with stake-like protrusions is attached to the opening of the container, and the multiple stake-like protrusions on the surface side of the container function as the scalp massager. A leaf spring operating part extends from the container, and a grip part is provided at the tip of the leaf spring operating part.

[0005] With this scalp massage and shoulder tapping device, by grasping the grip portion and tapping the scalp with the multiple stake-shaped protrusions (the stake-shaped protrusions on the surface side of the container), a moderate stimulation can be given to the scalp, resulting in a massage effect, and by tapping the shoulders with the multiple protrusions (the protrusions on the bottom side of the container), a moderate stimulation can be given to the shoulders, resulting in a shoulder tapping effect.

[0006] [Patent Document 1] Japanese Patent Publication No. 2020-178975 [Patent Document 2] Utility Model Registration No. 3047693 Summary of the Invention [Problem to be solved by the invention]

[0007] However, with this type of acupressure tool, the tip of the front half is pressed against an acupressure point, and so although it is possible to apply a moderate amount of pressure (stimulating force) to the acupressure point, the force that can be applied by this acupressure tool is a continuous pressure force, not an instantaneous impact force, and it is not possible to apply a moderate amount of stimulation like hitting.

[0008] Furthermore, in a scalp massage and shoulder tapping device, by grasping the grip portion and tapping the scalp with the scalp massage portion (multiple stake-shaped protrusions), a moderate impact force (stimulating force) can be applied to the scalp, and by tapping the shoulders with the shoulder tapping portion (multiple protrusions), a moderate impact force (stimulating force) can be applied to the shoulders, but since the impact force applied by the scalp massage portion and shoulder tapping portion is determined by the strength of the person, it is difficult to apply a constant impact force. Also, because this impact force is simply a tap, it is difficult to effectively stimulate acupressure points on the neck and shoulders.

[0009] An object of the present invention is to provide a stimulating device that can impart stimuli that effectively act on the skin, acupressure points, etc. [Means for solving the problem]

[0010] The stimulating device according to claim 1 of the present invention comprises a grip body having a receiving portion on its inner circumferential side, a stimulating member movably disposed on the tip side of the receiving portion within the grip body, an adjusting member disposed between the receiving portion and the stimulating member, a repulsive member disposed on the rear end side of the receiving portion within the grip body, and a repulsive member disposed between the repulsive member and the rear end of the grip body. and elastically biasing the repulsive member toward the receiving portion. a first elastic biasing member disposed between the receiving portion and the adjusting member; The adjusting member is elastically biased toward the stimulating member by the second elastic biasing member, and the elastic biasing force is smaller than the elastic biasing force of the first elastic biasing member. a second elastic biasing member; The receiving portion of the grip body is provided with an insertion opening through which the shaft portion of the adjustment member is inserted, and one end surface of the repulsion member is provided with a Immersion recess the shaft portion of the adjustment member is configured to be able to be inserted into the insertion recess of the repulsion member through the insertion opening of the receiving portion, Further, a contact end is provided on the base side of the stimulation member, and the end face of the contact end expands at an incline based on a plane perpendicular to the axial direction of the stimulation member, and a head is provided on the tip side of the adjustment member, and the tip end of the head is formed in a partially spherical shape, and the head of the adjustment member is configured to be elastically contacted with the end face of the contact end of the stimulation member by the second elastic biasing member, When the stimulating member is pressed down, the adjusting member is centered and the shaft portion is inserted into the insertion recess of the repulsive member. It is characterized by:

[0011] In addition, in the stimulating device according to claim 2 of the present invention, the stimulating member The end surface of the abutting end portion is The stimulating member is tilted at an angle of 3 to 10 degrees relative to a plane perpendicular to the axial direction of the stimulating member. It's spreading It is characterized by:

[0012] Furthermore, in the stimulating device according to claim 3 of the present invention, a tapered portion in which the outer diameter gradually decreases is provided in the middle of the shaft portion of the adjusting member, and a small diameter portion with a small outer diameter is provided from the tapered portion to the end, and the receiving portion of the grip body is provided with a concave surface, and in a normal state in which the adjusting member is pressed against the abutting end of the stimulating member by the second elastic biasing member, the small diameter portion of the adjusting member is abutted and supported by the receiving portion of the grip body, and when the stimulating member is pressed inward from this normal state, When lowered, the small diameter portion of the adjustment member moves radially inward along the concave surface of the receiving portion and then abuts against the end face of the repulsive member through the insertion opening of the receiving portion, and when the stimulation member is pressed down further, the repulsive member is pressed down via the adjustment member, and when the reduced diameter portion of the adjustment member moves to the insertion opening of the receiving portion, the reduced diameter portion is centered by the insertion opening of the receiving portion and the small diameter portion of the adjustment member is immersed in the immersion recess of the repulsive member. [Effects of the Invention]

[0013] According to the stimulating device of claim 1 of the present invention, a stimulating member and an adjusting member are disposed on the tip side of the receiving portion of the grip body, a repulsive member is disposed on the rear end side of the receiving portion of the grip body, a first elastic biasing member is disposed between the repulsive member and the rear end of the grip body, a second elastic biasing member is disposed between the receiving portion of the grip body and the adjusting member, and an insertion opening is provided in the receiving portion and a recess is provided in one end face of the repulsive member. With this configuration, in a normal state, the repulsive member is elastically held in contact with the receiving portion of the grip body by the action of the first elastic biasing member, and the adjusting member is held in contact with the stimulating member by the action of the second elastic biasing member. Then, from this state, when the stimulating member is pushed axially inward against the action of the first and second elastic biasing members and the shaft portion of the adjusting member is inserted into the recess of the repulsive member through the insertion opening of the receiving portion, the elastic biasing force of the first elastic biasing member is greater than that of the second elastic biasing member, so that the elastic biasing force of the first elastic biasing member is first transmitted to the stimulating member via the repulsive member and adjusting member, thereby initially providing a moderately large stimulus. Subsequently, the elastic biasing force of the second elastic biasing member is transmitted to the stimulating member, thereby providing a small stimulus. Thus, an initial relatively large stimulus and a subsequent relatively small stimulus can be continuously applied, thereby providing effective stimulation to the skin, acupressure points, etc. Furthermore, since the end face of the contact end of the stimulating member expands and inclines relative to a plane perpendicular to the axial direction of the stimulating member, the adjusting member that abuts against it is also inclined relative to the axial direction and is held in a state of abutting against the receiving portion of the grip body in a normal state. When the stimulating member is pushed inward from this normal state, the shaft of the adjusting member moves radially inward along the receiving portion of the grip body and is centered, so that it protrudes toward the repulsive member through the insertion opening.

[0014] Furthermore, according to the stimulating device of the present invention, the end face of the contact end of the stimulating member is inclined at an angle of 3 to 10 degrees relative to a plane perpendicular to the axial direction of the stimulating member, and is expanded and inserted. Therefore, in the normal state, the adjusting member that contacts this is also inclined at an angle of 3 to 10 degrees relative to the axial direction and is maintained in a state in which it contacts the receiving part of the gripping body. will be done.

[0015] Furthermore, according to the stimulating device of claim 3 of the present invention, a concave surface is provided in the receiving portion of the grip body, and a reduced-diameter portion is provided in the intermediate portion of the shaft portion of the adjusting member, so that when the stimulating member is pushed toward the tip side of the grip body by the action of the second elastic biasing member, the small-diameter portion of the adjusting member abuts and is supported by the receiving portion of the grip body, but when the stimulating member is pushed inward, the small-diameter portion of the adjusting member moves smoothly radially inward along the concave surface of the receiving portion and then abuts against the end face of the repulsive member through the insertion opening of the receiving member. When the stimulating member is pushed further downward, the repulsive member is pushed downward via the adjusting member, and when the reduced-diameter portion of the adjusting member is pushed down to the insertion opening of the receiving member, the reduced-diameter portion is centered by the opening of the insertion opening of the receiving member and the small-diameter portion of the adjusting member is retracted into the retracting recess of the repulsive member, and thus the adjusting member can be centered by pushing down the stimulating member and retracted as required into the retracting recess of the repulsive member.

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, one embodiment of a stimulating device according to the present invention will be described with reference to the accompanying drawings. In Figs. 1 to 3, the illustrated stimulating device 2 includes an elongated gripping body 4. In this embodiment, the gripping body 4 is composed of a front section 6 located at the tip end in the longitudinal direction (also referred to as the "axial direction"), a rear section 8 located at the rear end, and an intermediate section 10 disposed between the front section 6 and the rear section 8. The front section 6 and the intermediate section 10 are threadedly connected, for example, by a female threaded section on the front section 6 side and a male threaded section on the intermediate section 10 side, and the intermediate section 10 and the rear section 8 are threadedly connected, for example, by a male threaded section on the intermediate section 10 side and a female threaded section on the rear section 8 side. In this embodiment, the gripping body 4 is composed of three members (the front section 6, the rear section 8, and the intermediate section 10), but it may be composed of four or more members.

[0018] A stimulating member 12 that applies a stimulus, an adjusting member 14, and a repulsive member 16 are arranged in this order from the tip side inside the grip body 4. An annular receiving portion 18 is integrally provided on the inner peripheral surface of the grip body 4 (specifically, the intermediate portion 10), and the stimulating member 12 and the adjusting member 14 are arranged on the tip side of the grip body 4 across this receiving portion 18, and the repulsive member 16 is arranged on the rear end side.

[0019] In this embodiment, the stimulating member 12 has an elongated shaft 20 that protrudes outward through a distal opening 21 in the front part 6, and a head 22 is attached to the distal end of the shaft 20 that protrudes through the distal opening 21, with a contact end 24 provided on the base side. The head 22 is formed from, for example, an elastic material (such as synthetic rubber), and acts on acupressure points on the neck and shoulders of the human body, or on the skin of the face, to provide stimulation.

[0020] It is preferable that the head portion 22 is configured to be replaceable with the shaft portion 20 (for example, configured to be screwable), and it can be replaced and used depending on the purpose, such as a stimulation type with a tapered tip or a massage type with a rounded tip, and the degree of stimulation can also be adjusted by changing the hardness.

[0021] The contact end 24 of the stimulating member 12 projects radially outward from the shaft 20 in an annular shape, and its end face 26 is inclined by 3 to 10 degrees (inclination angle α: 3 to 10 degrees) from a plane 30 perpendicular to the axial direction 28 of the shaft 20, as shown in Fig. 3, with the inclination angle α preferably being 5 to 8 degrees. By inclining the end face 26 in this manner, the adjustment member 14 is positioned at an incline with respect to the axial direction of the grip body 4, as will be described later. The outer diameter of the contact end 24 is larger than the inner diameter of the tip opening 21 of the front part 6, as shown in Fig. 2, and therefore the stimulating member 12 will not slip out of the grip body 4.

[0022] Next, the adjustment member 14 will be described. The adjustment member 14 has an elongated shaft portion 32 and a head portion 34 provided at one end of the shaft portion 32. A reduced diameter portion 36 whose outer diameter gradually decreases is provided in the middle of the shaft portion 32, and the portion from the reduced diameter portion 36 to the head portion 34 forms a large diameter portion 38 with a large outer diameter, and the portion from the reduced diameter portion 36 to the other end forms a small diameter portion 40 with a small outer diameter.

[0023] The head 34 of the adjustment member 14 is formed in a partially spherical shape, and the spherical surface of the head 34 is configured to abut against the end face 26 of the abutting end 24 of the stimulating member 12. Because of this configuration, the abutting end 24 of the stimulating member 12 and the head 34 of the adjustment member 14 are in point contact, and the adjustment member 14 is positioned so as to extend from this contact point in a direction perpendicular to the end face 26 of the abutting end 24, as shown in Figure 3 (see Figure 3).

[0024] In relation to the above-mentioned configuration, a circular insertion opening 42 is provided in the center of the receiving portion 18 of the gripping body 4, and the inner diameter of this insertion opening 42 is larger than the outer diameter of the small diameter portion 40 of the adjustment member 14 and smaller than the outer diameter of its large diameter portion 38.By configuring in this manner, the small diameter portion 40 of the adjustment member 14 protrudes toward the repulsive member 16 through this insertion opening 42, but the large diameter portion 38 does not protrude toward the repulsive member 16 through this insertion opening 42.

[0025] The receiving surface 44 of the receiving portion 18 (the surface on the adjustment member 14 side) is a partially spherical concave surface, and an insertion opening 42 is provided at the bottom of this concave surface. Therefore, as will be described later, when the stimulating member 12 is moved so as to be pushed inward, the tip of the small diameter portion 40 of the adjustment member 14 moves smoothly radially inward along the receiving surface 44 of the receiving portion 18 toward the insertion opening 42, and then protrudes through the insertion opening 42 toward the repulsion member 16 side.

[0026] The repulsive member 16 is made of a cylindrical member, and one end face thereof (the end face facing the insertion opening 42 of the receiving portion 18) is provided with a recessed recess 46 that corresponds to the insertion opening 42 of the receiving portion 18 of the grip body 4. The recessed recess 46 has a circular cross section that corresponds to the shape of the small diameter portion 40 of the adjustment member 14, and its inner diameter is slightly larger than the outer diameter of the small diameter portion 40 of the adjustment member 14.

[0027] The recessed recess 46 of the repulsive member 16 extends in the axial direction, and the tip side of the small diameter portion 40 of the adjustment member 14, as will be described later, is recessed into the recessed recess 46 of the repulsive member 16 through an insertion opening 42 of the grip body 4 and abuts against the bottom thereof. The inner diameter of the recessed recess 46 is smaller than the inner diameter of the insertion opening 42 of the receiving portion 18 of the grip body 4, and the recessed recess 46 of the repulsive member 16 and its surrounding area are exposed to the adjustment member 14 side through the insertion opening 42.

[0028] In this embodiment, a first elastic biasing member 50 formed of, for example, a coil spring is disposed between the repulsive member 16 and the base end portion 48 of the grip body 4 (in this embodiment, the rear end wall portion of the rear portion 8). This first elastic biasing member 50 elastically biases the repulsive member 16 toward the receiving portion 18 of the grip body 4, and in a normal state, the repulsive member 16 is elastically held in contact with this receiving portion 18.

[0029] In addition, a second elastic biasing member 52, which is formed of, for example, a coil spring, is disposed between the receiving portion 18 of the grip body 4 and the head 34 of the adjustment member 14. This second elastic biasing member 52 is disposed so as to fit over the shaft portion 32 of the adjustment member 14, and elastically biases the adjustment member 14 toward the stimulating member 12. In a normal state, the adjustment member 14 is elastically held in a state in which its small diameter portion 40 is out of the insertion opening 42 of the grip body 4 and its head 34 is in contact with the contact end portion 24 of the stimulating member 12.

[0030] In this embodiment, the elastic biasing force of the first elastic biasing member 50 is configured to be greater than the elastic biasing force of the second elastic biasing member 52. With this configuration, when the pressing state of the first and second biasing members 50, 52 is released as described below, the elastic biasing force from the first elastic biasing member 50 is first transmitted to the stimulus applying member 12, followed by the elastic biasing force from the second elastic displacement member 52. As a result, the stimulus applying member 12 first applies a large stimulus, followed by a small stimulus, thereby enabling the stimulus applying member 12 to apply a two-stage stimulus that acts effectively on the human body, etc.

[0031] Next, the stimulating action of the stimulating device 2 described above will be described mainly with reference to Figures 4 to 7. To apply a stimulus using this stimulating device 2, the gripping main body 4 is gripped and the head portion 22 of the stimulating member 12 is placed against the area to be stimulated (for example, an acupressure point on the neck, shoulder, etc.), and in this state, the gripping main body 4 is pressed down to gently push the stimulating member 12 inward.

[0032] When the stimulating member 12 is lowered slightly inward in this manner, with the abutting end 24 of the stimulating member 12 and the head 24 of the adjusting member 14 in contact, the tip of the small diameter portion 40 of the adjusting member 14 moves radially inward along the receiving surface 44 of the receiving portion 18 of the gripping body 4, changing from the state shown in Figure 2 to the state shown in Figure 4.

[0033] If the stimulation member 12 is lowered slightly further inward from this state shown in Figure 4, it will reach the state shown in Figure 5, and when the abutment end 24 of the stimulation member 12 and the head 24 of the adjustment member 14 are in abutment, the tip of the small diameter portion 40 of the adjustment member 14 protrudes toward the repulsion member 16 through the insertion opening 42 of the receiving portion 18 and abuts against the end face of the repulsion member 16 (specifically, the area surrounding the immersion recess 46).

[0034] If the stimulation member 12 is lowered further inward from this state shown in Figure 5, it will reach the state shown in Figure 6, where, with the abutment end 24 of the stimulation member 12 and the head 24 of the adjustment member 14 in contact, the stimulation member 12 presses down on the adjustment member 14 against the elastic biasing force of the first elastic biasing member 52, and the adjustment member 14 presses down on the repulsion member 16 against the elastic biasing force of the first elastic biasing member 50.

[0035] If the stimulating member 12 is lowered further inward from this state shown in Figure 6, when the abutting end 24 of the stimulating member 12 and the head 24 of the adjusting member 14 are in contact, the reduced diameter portion 36 of the adjusting member 14 will lower to the insertion opening 42 of the receiving portion 18 of the gripping body 4, and this reduced diameter portion 36 will come into contact with the opening of the insertion opening 42 of the receiving portion 18, thereby centering the adjusting member 14 relative to the gripping body 4, and the tip side of the small diameter portion 40 of the adjusting member 14 will be aligned with the recessed portion 46 of the rebound member 16.

[0036] 7, the compressed state of the first and second elastic biasing members 50, 52 is released, but because the elastic biasing force of the first elastic biasing member 50 is greater than the elastic biasing force of the second elastic biasing member 52, the compressed state of the first elastic biasing member 50 is released first, and the elastic biasing force of this first elastic biasing member 50 causes the repulsive movement of the repulsive member 16 until it abuts against the receiving portion 18 of the grip main body 4. Then, during this repulsive movement, the small diameter portion 40 of the adjusting member 14 is immersed in the immersion recess 46 of the repulsive member 16 and abuts against the bottom thereof, and after this abutment, the stimulating member 14 also repulsively moves via the adjusting member 14 along with the repulsive movement of the repulsive member 16. Thus, the repulsive force from the first elastic biasing member 50 is transmitted to the stimulating member 12 via the repulsive member 16 and the adjusting member 14, and is transmitted from the head portion 22 of this stimulating member 12 to the human body (e.g., acupressure points on the neck, shoulders, etc.), and a relatively large stimulus is imparted by this stimulating member 12.

[0037] Subsequently, the second elastic biasing member 52 is released from its compressed state, and the repulsive force from the second elastic biasing member 52 is transmitted to the stimulating member 12, and then transmitted from the head portion 22 of the stimulating member 12 to the human body (e.g., acupressure points on the neck, shoulders, etc.), and the stimulating member 12 applies a relatively large stimulus followed by a relatively small stimulus.

[0038] In this way, the head portion 22 of the stimulation member 12 applies a relatively large stimulation transmitted by the release of the compressed state of the first elastic biasing member 50, followed by a relatively small stimulation transmitted by the release of the compressed state of the second elastic biasing member 52. In this way, two levels of stimulation, large and small, are applied successively, thereby making it possible to provide effective stimulation to the human body (for example, acupressure points on the neck and shoulders, or facial skin, etc.).

[0039] As can be understood from the above-described embodiment, for example, by adjusting the elastic biasing force (its spring constant) of the first elastic biasing member 50, the magnitude of the initial relatively large stimulus can be adjusted, and by adjusting the elastic biasing force (its spring constant) of the second elastic biasing member 52, the magnitude of the relatively small stimulus that follows the initial relatively large stimulus can be adjusted.

[0040] Although one embodiment of the stimulating device according to the present invention has been described above, the present invention is not limited to this embodiment, and various modifications and alterations are possible without departing from the scope of the present invention.

[0041] For example, in the above-described embodiment, the stimulating device is applied to the human body to provide effective stimulation to the acupressure points, skin, etc., but it is not limited to such use and can also be applied to provide stimulation to animals such as dogs and cats.
