Massager {MASSAGER}

The present invention relates to a massager, and more particularly, to a massager that can be used by switching the sample range when the sample is held and patted massage sample.

In the conventional portable massager, the sample portion may be reciprocally driven by using a driving means such as a solenoid or a motor, and the tapping massage sample may be performed on the sample subject. It is common. In such a general configuration, there is a problem that the sample range and the sample sense become single, and the massage effect is monotonous.

However, in the above proposal, since 1) the driving means is provided with the number of sample portions, the sample portion to be driven can be appropriately selected, but there is a problem that the massager is large and heavy and expensive.

Although the problem of 1) can be solved using only one drive means about 2), in the structure [1], the one-way clutch is provided in order to select the sample part driven according to the rotation direction of a motor, and a structure is complicated. In addition, since the plurality of sample portions are provided on both sides of the massaging machine, it is necessary to move the massaging machine every time the sample portion is switched. In the configuration [3], the monotone of the massage effect is not so much improved because a plurality of (two) sample sections are always driven alternately or simultaneously. In addition, in the configuration [5], it is said that by changing the degree of pressurization to the human body, a wide range of stimuli and a local stimulus can be switched. The difference is not clear, and the structure is complex for the conversion of the range. In addition, in the structure [6], it is a structure which changes the width | variety of a long sample part, Even if the width | variety of a long sample part is narrowed, the length of a sample range remains as it is, and the change of a sample range is not clear.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a massaging device that realizes a configuration that clearly changes a sample range and a sample interval with a small size and light weight suitable for a portable type.

In order to achieve the above object, the massaging machine of the present invention allows the main sampler and the subsampler to perform a sample operation on the head part, the main sampler and the subsampler, which are provided to vary the amount of protrusion from the head part. And a driving means for selectively detaching the bushing member from the bushing member, and the bushing member and the bushing member are arranged side by side in the longitudinal direction of the head portion.

According to this configuration, since the bushing member can be selectively detached from the feeder, and is arranged side by side in the longitudinal direction of the head portion, when the busher is operated in a state in which the bushinger is engaged with the feeder, the sample range is the feeder. When the sample operation is performed in a state where the ruler and the busher are combined and the busher is not engaged with the caregiver, only the caregiver performs the sample motion, and the sample range is larger than the case in which the bushworker is engaged with the caregiver. By reducing, the sample range and the sample interval can be clearly changed.

The busher has a movable range that is larger than the movable range in the sampler's sample operation, and the one end side where the protrusion amount from the head portion is the maximum in this movable range has the largest protrusion amount from the head portion in the operator's movable range. It is suitable to make it correspond to the one side which becomes. As a result, it is possible to change the sample range and the sample interval more clearly without the busher contacting the sample part of the user when the busher is not engaged with the caregiver, that is, only the caregiver performs the sample operation. Can be.

The operator and the bush are pivotally pivotally provided at one end of the head portion, respectively, and the center of rotation is preferably orthogonal to the longitudinal direction of the head portion. As a result, the structure of each sampler can be simplified, and a small size and a light weight suitable for a portable type can be realized.

The engagement means is composed of an engagement portion provided on the bushing member, an engaged portion on the side of the doser installed on the doser, and an engaged portion on the head side, provided on the head portion, and the engagement portion is engaged with an engaged portion on the doser side. In this case, it is suitable that the subject and the subject perform the sample operation integrally, and when the engaged portion is engaged with the engaged portion on the head side, only the subject administers the sample operation. According to this configuration, since only the attendant performs the sample operation, the bushing member does not engage with the head, and thus, unpleasant vibration and noise can be prevented from occurring.

The engaging portion is provided on the bushing member so that the engagement state and the disengagement state of the engaged portion and the disengaged state on the feeder side and the head portion side can be switched, and are pressed in the engagement direction with the engaged portion on the feeder side and the head side. Suitable. As a result, it is possible to easily detach the busher and the chief drinker, and to realize a secure shift to the engaged state.

It is preferable to have release holding means for maintaining the disengagement state when the engaging portion is not engaged in any of the engaged portions on the doser side and the head side. According to this configuration, the engagement portion pressed in the engagement direction to the engagement portion is disengaged from the engagement portion when the transition from the non-engagement of the operator to the engagement portion of the head portion and the head portion to the engagement state is carried out. Operation such as making a state becomes unnecessary.

It is preferable that the engagement between the engaging portion and the engaged portion on the head side is performed at the other end side of the movable range of the bushing member. According to this configuration, the engagement between the bushing material and the head portion can be easily and surely realized.

It is suitable to have a release means for releasing the engagement state between the engagement portion and the engagement portion on the doser side and the head portion side. Further, the release means is provided so as to protrude from the head portion, the operation portion operated in the moving direction when the engagement portion releases engagement with the engaged portion on the doser side and the head portion side, and the engagement portion in the release direction in accordance with the movement of the operation portion. It is suitable to have a release to move to. As a result, the disengagement between the engaging portion and the engaged portion can be easily and surely realized.

The release portion is preferably formed in an arc shape according to the rotational trajectory of the engaging portion following the rotation of the bushing material. As a result, there is no difference in the amount of movement of the operation portion and the force required for the operation when releasing the engagement between the engagement portion and the engaged portion in the case where the bushing member is engaged with the feeder and the head portion. .

It is preferable that the busher is pressed in the direction exiting from the head portion. As a result, even when the engaging portion is not engaged with any of the subject and the head, the bushing member automatically shifts to the engaged state with the subject, so that the sample range and the sample interval can be easily and reliably realized.

The hook receiver 70 and the fixed hook 90 constitute a coupling means.

The bushing element 80 (FIG. 8) is located between the pair of arms 62 of the feeding ruler 60, and has a rubber (not shown) covered on the outside and an arm 81. As shown in FIG.

The through hole 82 formed in the proximal end of the arm 81 of the bushing member 80 and the through hole 64 formed in each proximal end of the pair of arms 62 of the supervisor 60 have a shaft 65. ) Is inserted through, and both ends of the shaft 65 are inserted into the boss 26 provided on the proximal side of the inner left housing 21 and the inner right housing 22, whereby the feeder 60 and the busher ( 80 is pivotably pivoted about the inner left housing 21 and the inner right housing 22 ((the outer left housing 11 and the outer right housing 12). The bushing member 80 can be rotated individually about the axis orthogonal to the longitudinal direction of the head part 3, respectively.

Moreover, in the shaft 65, the spring 66 is inserted inside the arm 81 of the bushing element 80, and this spring 66 looks at the bushing element 80. ) Is always pressed in the direction (outward from the head portion 3) to be sent outward between the pair of arms 62. In addition, the spring 66 is shown in FIG. 7 as being inside the pair of arms 62 of the operator 60. In addition, in the shaft 65, the portion between the arm 62 of the bottle holder 60 and the arm 81 of the busher 80 is placed between the holder 60 and the busher 80. The washer 67 is interposed so that each may rotate smoothly individually.

The bushing member 80 is attached with a fixing hook 90 made of a component as shown in FIG. Fig. 9 shows these perspective views, Fig. 10 is a front view, Fig. 11 is a plan view (top view), and Fig. 12 is a sectional view along the line A-A of Fig. 11. However, although the shape is slightly different in what is shown in FIG. 8 and FIG. 9-12, the basic structure is the same.

The fixed hook 90 has a bar 91 and a two-pronged pivot leg 92 having a through hole 93 formed therein. The shaft 94 is inserted through the through hole 93 of the pivot leg 92 of the fixing hook 90 so that the shaft 94 is supported by the shaft case 95. The shaft case 95 is coupled to the inside of the bushing member 80 and fixed by the screw 96. Accordingly, the fixed hook 90 protrudes from the bushing member 80 and is rotatable around the shaft 94 within the movable range, so that the hook receiver 70 and the inner right housing 22 described later are provided. It is possible to switch between the engaged state and the disengaged state with respect to the engaging groove 34 on the inner side of the. A portion of the shaft 94 between the bushing member 80 and the pivot leg 92 of the fixing hook 90 is provided with a washer 97 for smoothly rotating the fixing hook 90.

Is always pressed in the direction of the hook receiver 70.

On the other hand, Figs. 7 and 13 (front view of the inner right housing 22 viewed from the inside with the subsampler 80 fixed to the feeder 60) and Fig. 14 (in the state of Fig. 13). Enlarged perspective view of the main part of FIG. 15, FIG. 15 (front view of a part of fracture in a normal state when the subsampler 80 is fixed to the feeder 60), and FIG. Partial broken front view in a state where the ruler 60 is inserted most], FIG. 17 (partial broken front view in a normal state when the subsampler 80 is fixed to the inner right housing 22) 18 (partial broken front view in the state where the feeder 60 was inserted most in the case of FIG. 17), FIG. 19 (the subsampler 80 was fixed to the feeder 60). Enlarged side view of the main part at the time of], and FIG. 20 (expanded side view of the main part when the subsampler 80 is fixed to the inner right housing 22); Likewise, the release lever link 110 for pressing the fixing hook 90 includes an arc-shaped lever 111 (release portion) and an attachment piece 112.

This release lever link 110 has its attachment piece 112 coupled to the engaging portion 30 provided inside the inner right housing 22, while its one end 110a is inside the inner left housing 21. Is inserted into the boss 31, and the other end 110b is inserted into the through hole 32 of the inner right housing 22. The other end 110b protrudes from the through hole 32 of the inner right housing 22 (FIG. 5), and the release operation button 115 (operation part) shown in FIGS. 1 to 4 is attached to this protruding portion. do. The release lever link 110 and the release operation button 115 constitute a release means.

The lever 111 of the release lever link 110 is inserted into the space 99 (FIG. 9) formed by the fixing hook 90 and the bar 91. Thus, when the button 115 emerging from the outer right housing 12 is pressed, the fixing hook 90 is moved by the lever 111 to the opposite side of the hook receiver 70 against the pressing force of the spring 98.

On the other hand, when the bar 91 of the fixing hook 90 is engaged with the engaging groove 70a of the hook receiver 70 (FIGS. 13 to 16 and 19), the bushing member 80 receives the feeder 60. ) Is fixed to the coupling groove 34 (the engaging portion on the head side) and the coupling groove 35a of the later guide rail 35 formed in the inner side of the inner right housing 22. 17, 18, and 20, the bushing element 80 is fixed to the inner right housing 22. As shown in FIG.

The bushing member 80 has the upper limit fixed position where the bar 91 couples with the coupling groove 34, and the position where the bar 91 couples with the hook receiver 70 as the lower fixed position. It becomes rotatable in between. In the vicinity of the lower limit fixed position, the bar 91 and the hook receiver 70 are engaged, and the bushing member 80 meshes with the feeder 60 to operate integrally. Therefore, the lower limit fixed position of the busher 80 corresponds to a position where the amount of protrusion from the head portion of the movable range in the sample motion of the monitor 60 is maximized. In addition, the upper limit fixed position of the busher 80 is set above the upper limit position of the movable range in the sample operation of the supervisor 60, and the busher 80 is the supervisor 60 It has a larger operating range than that of. In addition, when the button 115 is pressed while the bar 91 is engaged with the engaging groove 34 or the hook receiver 70, the engagement is released.

In addition, when the button 91 is pressed while the bar 91 is coupled to the hook receiver 70, the bushing member 80 tries to move out of the head portion 3 by the pressure of the spring 66. In the state where the bar 91 is separated from the hook receiver 70, the fixing hook 90 contacts the stopper 68 (FIG. 7) provided on one arm 62 of the feeder 60. The sample ruler 80 does not rotate beyond the lower limit fixed position.

Specifically, when the button 91 is pressed in the state in which the bar 91 is engaged with the hook receiver 70 and the bushing member 80 is pushed into the head portion 3 against the pressing force of the spring 66, The bar 91 engages in the engaging groove 34 of the inner right housing 22. Accordingly, the bushing element 80 is fixed to the inner right housing 22 so that the bushing element 80 is locked in the most retracted state in the head portion 3. In this state, only the attendant 60 performs the floating sample operation. On the contrary, when the button 115 is pressed while the bar 91 is engaged with the engaging groove 34 of the inner right housing 22, the bushing member 80 is pressed by the spring 66 to the head 3. Rotating in the direction of protruding from the bar 91 is coupled to the hook receiver 70. Thereby, the bushing element 80 is fixed to the feeder 60, and the bushing element 80 is locked in the state which protrudes from the head part 3 most. In this state, the supervisor 60 and the subordinate 80 perform a sample operation.

Further, when the bushing member 80 moves within the movable range, a guide rail 35 is provided inside the inner right housing 22 so as to reliably lock to either the upper limit fixing position or the lower limit fixing position. The guide rail 35 is a hook receiver with the bar 91 of the fixing hook 90 against the pressing force of the spring 98, with the bushing member 80 between the upper and lower fixing positions. In order to maintain the state (unengaged state) rotated to the opposite side of 70, it is formed so that it may contact with the front-end | tip extended in the horizontal direction of the bar 91 of the fixing hook 90, and the guide rail 35 will hold | maintain release | release. Configure the means.

Accordingly, when the button 115 is pressed and the bar 91 is released from the engaging portion 34 of the hook receiver 70 or the engaging groove 34 of the inner right housing 22, the bushing member 80 has an upper limit. It is maintained until either one of a fixed position or a lower limit fixed position is reached, and the bushing member 80 is reliably locked to either an upper limit fixed position or a lower limit fixed position. The guide rail 35 has a coupling groove 35a to which the tip of the bar 91 engages in the upper limit fixing position of the bushing member 80, and at the same time as the coupling groove 34, the bar 91, i.e. It plays a role of fixing the bushing material 80 to an upper limit fixed position.

On the other hand, the lever 111 of the release lever link 110 for releasing the locking of the fixing hook 90 has an arc shape as shown in Figs. 13 to 18, which is fixed hook 90 in order to suppress the generation of unnecessary moments. It is for contacting the lever 111 to almost the center part of the left-right direction of the lever base 90a of the fixing hook 90 as much as possible without depending on the position of (). That is, as the bushing material 80 rotates between the upper limit fixing position and the lower limit fixing position, the fixing hook 90 draws an arc-shaped trajectory around the through hole 82 of the bushing material 80. The lever 111 is extended to follow the arc of the arc. Accordingly, the lever 111 contacts almost the center portion of the left and right directions of the lever base 90a of the fixing hook 90 regardless of the position of the fixing hook 90, so that the lever 111 is not twisted. The same unnecessary moment does not occur. Moreover, the displacement amount of the lever 111 at the time of moving or stopping the bushing material 80 with respect to the position of the fixing hook 90 (the position of the sub-sample material 80) is not changed, and the button 115 is not changed. May be a constant force and a constant amount. As a result of these, the response of the fixing and unlocking of the user 80 to the operation of the button 115 becomes good.

In the massage device 1 configured as described above, in order to contribute to the sample operation together with the subject 60 and the bush 80, the fixed hook 90 is engaged with the hook receiver 70, and the bush 80 ) Is fixed to the caregiver 60. At this time, when the fixing hook 90 is engaged with the engaging groove 34 of the inner right housing 22, pressing the button 115 releases the locking, and thus the spring 66 along the bushing 80 By the pressing force, the bushing member 80 rotates in the direction which protrudes from the head part 3, and the fixed hook 90 engages with the hook receiver 70. As shown in FIG. In the normal state when the busher 80 is fixed to the feeder 60 integrally, the feeder 60 and the busher 80 are driven by the spring 49 of the solenoid assembly 40. It protrudes from the head part 3 (FIG. 15).

Here, when the power switch 7 is turned ON, as the plunger 43 of the solenoid assembly 40 is pulled against the pressing force of the spring 49, the operator 60 and the operator 80 will It moves in the direction into the head part 3 (FIG. 16). As the plunger 43 reciprocates, the doser 60 and the busher 80 repeatedly move in and out, and a sample (tap operation) is applied to the sample site (for example, the shoulder). In this sample operation, since the dose meter 60 and the bushing element 80 are arranged in a straight line in the longitudinal direction of the head portion 3, the sample operation is performed over a long linear range.

When only the feeding ruler 60 is to be used, the button 115 may be pressed, and the bushing ruler 80 may be pushed into the head portion 3. Then, the fixed hook 90 shifts from the engagement state with the hook receiver 70 to the engagement state with the engagement groove 34 of the inner right housing 22, so that the bushing member 80 moves to the inner right housing 22. It is fixed to). In the normal state when the bushing member 80 is integrally fixed to the inner right housing 22, the feeding ruler 60 protrudes from the head portion 3 by the spring 49 of the solenoid assembly 40. However, the busher 80 remains as it is drawn into the head portion 3 (FIG. 17).

In the case where the massage device 1 is brought into contact with an object to be treated such as a shoulder from above, the sampler 80 is pushed into the head portion 3 only by pressing the release operation button 115. This is because the locking between the fixed hook 90 and the hook receiver 70 is released by pressing the release operation button 115 so that the bushing member 80 and the head portion 3 become relatively rotatable. This is because the head 3 is relatively rotated so that the lower surface is lowered by its own weight with respect to the bush 80 supported by the sample site such as the shoulder. At this time, the bar 91 of the fixing hook 90 is engaged with the hook receiver 70 or the inner right housing 22 until the bushing member 80 reaches the upper limit fixing position by the guide rail 35. The state released from engagement with the groove 34 is maintained. Therefore, after the engagement with the hook receiver 70 is released, the fixed hook 90 can transition to the engagement state with the engagement groove 34 of the inner right housing 22 reliably.

Here, when the power switch 7 is turned ON, the plunger 43 of the solenoid assembly 40 is pulled in against the pressing force of the spring 49, so that only the feeder 60 enters the head portion 3. (Fig. 18). Only the examiner 60 repeats the entry and exit operation, so that the sample (tap operation) is performed on the sample portion (for example, the shoulder portion). In this case, since only the attendant 60 contributes to the sample operation, the sample operation is performed only in a linear short range.

As described above, according to the massager 1, when the button 115 is pushed out of the head portion 3, the busher 80 can be changed to a wide range of sample operations, and the button 115 is pressed down. When 80 is pushed into the head part 3, it can change into a narrow range of sample motions, and the sample part extended in the longitudinal direction of the head part 3 (main sampler 60 and the bushing part 80). The length of can be made variable. Moreover, a configuration that clearly changes the sample range and sample interval can be realized with a small size and light weight suitable for a portable type.

According to the present invention, it is possible to clearly change the sample range and the sample spacing because the subject and the subject can select and carry out the sample in the state in which the head part extends in the longitudinal direction and the sample only by the subject. Moreover, such a configuration can be realized in a small size and light weight suitable for a portable type.
