Description

Masseur

The present invention relates generally to masseur, more specifically relates to hand-held masseur, and it is suitable for continuously and repeatedly back and forth movement is applied on a plurality of adnexaes, so that repeatedly pat skin surface by the elasticity of spring.

By repeatedly pat skin surface chafe or muscle as health care and keep body configuration's masseur be public as.Existing most of masseur has an adnexa, this adnexa by when stretching, discharge be stored in that spring or other intravital energy of elasticity that constitutes adnexa can come and go repeat to pat skin surface.Therefore, existing masseur must move they oneself, and thus, to avoid repeatedly patting the same area of skin, when frequency was patted in minimizing, they were subjected to structural restriction again.

In order to overcome above-mentioned shortcoming, can install to a plurality of adnexaes on the masseur.Yet, with regard to existing structure, being necessary for each adnexa of driving and being equipped with independent driver element, this just causes the masseur increased in size, and therefore is not easy to hand.Therefore, existing masseur with this structure, be stored in promptly that spring or the intravital energy of other elasticity discharge when stretching, tend to give the too strong action of patting, give discomfort user to skin of head or other position of human body with subcutaneous Musclar layer of relative thin.

In order to overcome above-mentioned shortcoming, the applicant once proposed a kind of small and exquisite portable masseur, and it can softly pat skin massaging (the Japan Patent JP-1 of skin surface to wider range by a plurality of adnexaes that driven by a single driver, 745,268 and U.S. Pat-5,088,474).

The part of an embodiment of above-mentioned improvement invention that illustrated in figures 1 and 2 is is cutd open side view and the front view that shows.In Fig. 1 and Fig. 2, label 1 is to be used for installation of driver 2 and the housing of the adnexa 3 that driven by driver 2.Label 4 is the hollow cylindrical adnexa isolators that removably install on the housing 1.Label 5 is the switches that are contained on the housing 1, so that start or close the motor 6 of formation driver 2.

Adnexa 3 comprises an accessory drive axle 7, this power transmission shaft passes driver 2 in the axial direction, so as can before and after back and forth movement, at the head of accessory drive axle 7 preface successively connector 8 is housed, bolster 9 and pat part 10, lift arm 11 is contained in the rear end of accessory drive axle 7 regularly.Three adnexaes 3 are contained on the same circumference at interval with equal circumference.

Label 12 is safetied pins outstanding on the front surface of driver 2, with prevent adnexa 3 by with connector 8 on rotate being connected of hole 8a.Label 13 is to be contained in compression helical spring on the accessory drive axle 7 regularly on the accessory drive axle 7 that is contained in the spring container that provides on the driver 2 14 and by fixing pin 15.

Label 16 is the end cams that install on the final drive shaft 17, and this final drive shaft is the output shaft of driver 2, presses a kind of like this mode so that can rotate.Adnexa 3 can move when the end face of the end cams 16 of lift arm 11 edge shapings slides vertically.That is end cams 16 is to form by this way, and promptly the axial length from its axis of its planar quadrature to its end face is according to the angle change in location of rotating, and thus, the two-way time of adnexa 3, the position, angle according to its rotation changed continuously.

Press said structure, when the motor 6 of driver 2 drove by connecting switch 5, the rotation of motor 6 was transferred to final drive shaft 17 by the reduction box (not shown) in driver 2, makes end cams 16 rotate.Consequently, the lift arm 11 that accessory drive axle 7 slides by the end face along end cams 16 is back and forth movement in the axial direction, thereby makes adnexa 3 back and forth movements.The adnexa 3 that shown in Figure 1 is on top moves most advanced position, and the adnexa 3 of lower part is withdrawal backward then.

The part 10 of patting on adnexa 3 heads is suitable for protruding slightly from the end face of adnexa isolator 4.When three adnexaes 3 are driven by driver 2 in regular turn, pat part 10 and repeatedly pat skin surface successively, to massage.Because three adnexaes 3 are by consistent stroke back and forth movement, and massage is to carry out under the situation that end face keeps with skin surface contacts of adnexa isolator 4, so each is patted part 10 and pats skin surface equably.That is, because patting part 10, each always keeps constant from the protrusion length of adnexa isolator 4, therefore, pat to try hard to keep and hold uniformity, as long as masseur is to carry out under the end face of adnexa isolator 4 and situation that skin surface contacts by what each patted that part 10 applies.With regard to above-mentioned improved invention, soft massage can be finished in bigger skin scope, but finds that also some problem still exists.

In the structure of above-mentioned improvement invention, still be contained on the accessory drive axle 17 in the spring container 14 that provides on the driver 2 and fix as the compression helical spring 13 of energy storing device with fixing pinning 15, this just brings some difficulties to assembly manipulation.When assembly manipulation, compression helical spring 13 is through earlier on the accessory drive axle 7, and in this case, spring 13 temporarily places in the spring container 14.Yet in this case, compression helical spring 13 is allowed in spring container 14 freely to move, and making it is accessory drive axle 7 difficulty very that is passed in the spring 13.

Therefore, rotate, by the hole 8a engagement on driver 2 front surfaces safetied pin 12 that protrudes and the connector 8 that constitutes adnexa 3 for preventing adnexa 3.When carrying out simultaneously, make the two operation very difficult when this operation and adnexa rotating shaft 7 insertion compression helical springs 13.

When lift arm 11 bump end cams 16, be used to make the end face of the end cams 16 of adnexa 3 back and forth movements to constitute the profile that a gradient ground tilts, to avoid lift arm 11 to produce bigger mechanicalness noise, at this moment adnexa 3 moves to top position from retracted position, discharges the energy of being stored with the elasticity that stops compression helical spring 13 instantaneously.By formed the end face of end cams by this appearance profile, partly the energy of storage has been lost, and is transferred to the energy of patting on the part 10 so that reduce.

The present invention is intended to overcome the problem that exists in the aforementioned improved invention, the object of the present invention is to provide a kind of masseur that is easy to assemble and be suitable for using effectively the energy of being stored.

In order to realize these purposes, comprise a plurality of adnexaes of patting skin according to masseur provided by the present invention, these adnexaes are by driver and the energy storing device energy back and forth movement with spring, wherein, energy storing device is the front in driver, and buffer unit is in its back; Two devices all are made of compression helical spring, be used to make the cylinder-shaped end cam and the lift arm engagement that is fixed to the adnexa rearward end of adnexa back and forth movement, the safetied pin that provides on the driver rear side is used to prevent the adnexa rotation and is connected with lift arm, thus, adnexa is driven by driver successively by the rotation of end cams.
