Description

  This device stimulates the body by hitting the body, improves blood circulation, removes fatigue, enhances muscle function, massages to relieve tension, etc. With regard to instruments and control panels applicable to skeletal correction using muscle slacking to vibrate, mechanically vibrates mainly in the front-rear direction on the surface of the body part requiring massage, instead of using the manual tapping method. The present invention relates to an electric massager that strikes and massages the body by pressing the tip of a vibrating head and a control panel thereof.

  Traditionally, massage is a type of treatment that is performed in Western medicine, mainly by applying mechanical stimulation to the skin, such as touching, rubbing, hitting, or pushing the skin with fingers or palms. This massage usually requires specialized knowledge and skill, but in order to loosen the stiffness at home, hitting and kneading the elaborate portion, such as stroking the shoulder, is generally performed. It is a deceiving act.

  By the way, instead of such an artificial action, a massage chair or foot, which is a large instrument that strikes and massages a necessary part using a roller-like instrument or a tapping instrument made by machine operation, massages the entire body, or the like. Various small appliances have been developed that massage only the upper and lower back.

  On the other hand, chiropractic was founded in the United States as one of the spine correction techniques. In this chiropractic, based on the idea that the disease is caused by a nervous system dysfunction, the vertebrae between the narrowed vertebrae are conditioned by “hand surgery” by manually impacting the spinal abnormalities and adjusting the abnormalities. A treatment to restore normal function of the foramenum, restore nerve function by eliminating nerve pressure, and correct abnormalities in the function of the tissues and organs under control. It is a way to try to recover.

  Conventionally, an electric chiropractic correction instrument composed of a handy type used to correct a joint disorder by hitting like this has been devised and disclosed (for example, see Patent Document 1). As a correction method for joint disorders, the patient's neck and body should not be anxious when the patient's neck or body is bent or twisted, and a chiropractic effect can be obtained even if the patient is not a skilled practitioner. This is a handy type electric chiropractic instrument that is described as having been made. However, this chiropractic instrument is composed of a lower cylinder in the first half and an upper cylinder in the second half, and the elastic rubber body at the tip of the striking rod protruding partly outside from the tip of the lower cylinder is used as an affected part to be treated by the patient. Push down. Next, the hitting rod, which is a movable body, is pushed into the small pipe in the lower cylinder by this depression, and the spring on the rear end side in the small pipe is compressed against its resilience, and the rear end of the pushed hitting rod Is brought into contact with the front end of a rod-shaped iron core extending from the latter half of the solenoid housed in the latter half of the lower cylinder to the upper cylinder. In this case, the rear end of the striking rod that is in contact with the front end of the rod-shaped iron core that is magnetized by energization of the solenoid to become an electromagnet is attracted and fixed. In this state, by pressing the switch to cut off the current supply to the solenoid, the striking rod is released from the rod-shaped iron core, and the rod-shaped iron core is compressed by the spring that is compressed to the rear end side in the small pipe. Is energized at once, and the rubber elastic body at the tip gives the patient a single hit. However, this one has a spring further in front of the above-mentioned spring in the small pipe so as to relieve compression, but the pushing force to the affected part of the rubber elastic body at the tip is too strong and it is fragile. There is.

  In addition to the above-mentioned electric chiropractic orthodontic appliance, the movable body is vibrated back and forth by the magnetic force of the solenoid and the biasing force of the spring, and the operation for massage is smooth when hitting the human body with the interlocking contactor The movable body is contained in a housing whose axial center extends in the front-rear direction and is movable in the front-rear direction, and the movable body is contained in the housing. A solenoid that can be attracted toward the side, a spring that urges the movable body toward the front end of the housing against the suction force of the solenoid, and a human body that can be attached to the front end of the movable body and contact the human body In a massager equipped with a contactor to be vibrated back and forth, a grip is attached to the end surface of the rear end of the housing and can be gripped by the operator. Was massager has been proposed (e.g., see Patent Document 2.). By the way, according to the above, this device is “a solenoid that can attract the movable body toward the rear end side of the housing by magnetic force” and is movable with the solenoid in the positional relationship shown in the drawing of Patent Document 2. In the body, the movable body having the iron cylindrical body is arranged to be shifted rearward from the solenoid. Then, the movable body is attracted toward the rear end side of the housing by the magnetic force of the solenoid, and when the energization of the solenoid is stopped, the movable body is biased by the spring at the rear end and the iron cylinder moves to the front stopper. It is what. However, in order to prevent the grip from becoming too hot due to heat generation due to energization of the solenoid, a grip is separately attached to the rear end of the housing having the solenoid. The length of the cavity in the direction is shown in the drawing as being longer than the length of the solenoid present in the interior space of the housing housing the solenoid, and as such, as described in paragraph 0045 of the specification. In addition, heat transfer is suppressed. However, for this reason, the length of the grip in the solenoid direction is long, and it is long and difficult to handle.
