These vibration devices do not require a large amount of energy because the vibration in the downward direction is along the direction of action of the weight of the user or the weight of the device such as a wheelchair when the vibration of the vibrator is up and down. Since it is in the opposite direction (vibration load direction) to these gravitational forces, much of the output energy of the vibrator is consumed by upward vibration energy that is the vibration load direction.
In consideration of the above fact, the present invention assists the elastic actuator in the vibration load direction by assisting the elastic body with the elastic force in the same direction as that of the vibration load direction. It is intended to realize downsizing, downsizing and cost reduction.

  The apparatus of the present invention for solving the above-mentioned problems is as follows. First, the vibrator 1 that vibrates in small increments in the vertical direction and the body of the user mounted on the upper portion while being supported by the vibrator 1 are vibrated. A vibration imparting device comprising a diaphragm 2 for giving a vibration to the support portion 4 that supports the vibrator 1 in a vibration load direction that is a direction in which a load during vibration is large and elastically assisting. It is characterized in that a support device 12 including an elastic body 11 is provided.

  Second, the elastic body 11 is characterized by being made of elastic rubber or plastic material or foamed material thereof.

  Third, the elastic body 11 is a spring.

  Fourth, the elastic body 11 is an air cushion formed by enclosing air.

  Fifth, the support device 12 includes an adjustment mechanism 13 that adjusts the vertical height of the support device 12.

  Sixth, the grounding base 3 is provided on one of the upper and lower surfaces of the vibrator 1, and the diaphragm 2 is attached to the other surface of the vibrator 1, and the support device 12 is interposed between the grounding base 3 and the diaphragm 2. It is characterized by interposing.

  Seventh, the vibrator 1 and the diaphragm 2 are separated and molded separately, the support device 12 is grounded on the floor surface 4 as a support portion, and the vibrator 1 is installed. The vibration plate 2 is arranged in a manner such that the vibration plate 2 is placed in contact with and placed on the vibration device 1 in a state where at least a user is on board.

  Eighth, a user who has installed the vibrator 1 on a suspension device 18 that is lifted on the ceiling side in the building and has a mechanism for moving and / or changing the position of the place, and boarded on the suspension device 18 It is characterized by imparting vibration to the body.

The present invention configured as described above has specific effects as described below.
(1) Since the vibration plate is elastically assisted in a vibration load direction in which the vibration load is always large due to the elastic body, when the user gets on the board and receives vibration, the vibrator is weighted by the user, wheelchair, etc. Since the load on the vibrator is reduced by receiving a negative load in the direction of reducing the weight load, there is an advantage that power saving and downsizing of the vibration actuator can be realized.
When the user rides on the diaphragm, the diaphragm is always assisted in the direction of vibration load by the elastic body, so there is no tilting or shock due to uneven load at the time of riding, or even if there is tilting, it is buffered by the elastic body There are advantages to being.
(2) Further, by using elastic or elastic rubber or plastic material, the structure and assembly of the support part can be simplified and the cost can be reduced. On the other hand, when a spring such as a coil spring is used as the elastic body, the durability is improved.
Furthermore, by providing an adjustment mechanism that adjusts the vertical height of the support part, the elasticity of the elastic body can be adjusted according to the weight load, and the vibrator and diaphragm are separated and separated. Then, the distance between the diaphragm and the upper surface of the vibrator can be adjusted.
(3) In the case where a diaphragm and a grounding base are attached to the top and bottom of the vibrator, and a support device is interposed between the two, the entire device is integrally configured, so handling and installation are easy. It is. Moreover, what comprised the vibrator and the diaphragm separately has the advantage that a diaphragm with a different size and height can be selected and used in accordance with the place of use and conditions of use. Furthermore, if the suspension device is provided with a vibrator, it can also be used for bathing or other nursing care for the handicapped.

It is a front view which shows this invention apparatus and its use condition. It is a side view of this invention apparatus. It is a side view of 2nd Example which applied this invention apparatus using a spring as an elastic body to the hanging type | mold for care. It is a side view which shows 3rd Example of this invention.

  1 and 2 show a vibration imparting device according to a first embodiment of the present invention. A top or bottom of a vibrator 1 is made of a wooden board or the like, and has a square or rectangular shape protruding from front, rear, left and right of a rectangular vibrator 1 in plan view. A diaphragm (top plate) 2 and a grounding base 3 are attached, and the grounding base 3 is disposed on a floor surface 4 as a support portion.

  The vibrator 1 is, for example, a small one having a longitudinal length of 23 cm, a lateral width of 18 cm, and a height (thickness) of about 11 cm. The vibrator 1 operates with a normal household power source and has a remote controller (not shown). . The frequency and time are set according to the purpose and conditions by the remote controller. The driving source of vibration is not limited, but for example, a power supply of 100 V, an output of 50 W is rated, and a rhythm (fine vibration) with an amplitude of about 2 mm in the vertical direction at 5.6 to 13 Hz is used. It is a well-known product that is already on the market and can be subjected to vibration therapy by being placed on a part of the body of a healthy person or the whole body and receiving vibration treatment.

  The diaphragm 2 has a structure in which vibration can be imparted to the entire human body via the diaphragm 2 and the wheelchair 6 by mounting the wheelchair 6 on which the person is riding by the front and rear wheels 7 and 8. The front and rear ends (entrance / exit ends) of the diaphragm 2 have rising slopes toward the ends, and are smooth with respect to the upper surface by the wheels 7 and 8 by the operation of the user (subject, subject of treatment). A road plate-like guide member 9 that enables getting on and off is disposed.

  The diaphragm 2 has a strength and a large size (550 × 800) that allow the wheelchair 6 to be mounted on the small vibrator 1, and the vibrator 1 is attached to the center portion by the mounting flange 10 and the screw. The grounding base 3 is fixed in size and is the same size as the diaphragm 2 in this example.

  However, the diaphragm 2 and the grounding base 3 do not have to be plate materials, and the device itself can be placed or mounted on a support portion such as a floor surface, and if a person or a wheelchair can be mounted on the upper surface side, the shape structure, etc. There is no need to stick to it.

  Between the four corners of the diaphragm 2 and the grounding base 3, a support device 12 including an elastic body 11 that assists vibration in the upward direction of the diaphragm 2 is inserted, and the elastic body 11 can be adjusted in vertical height. The adjusting mechanism 13 made of a jack or the like is accommodated and supported in a spherical concave portion at the top, and is elastically pressed against the lower surface of the diaphragm 2.

  In this example, the support device 12 has the elastic body 11 pressed against the diaphragm 2. However, the support device 12 may be turned upside down, and can be detachably attached to either the upper or lower side as shown in the figure. It may be done.

  Further, since the elastic body 11 is a tennis ball and is formed into a ball shape having elasticity such as rubber or plastic, it can be easily inserted between the diaphragm 2 and the grounding base 3. The shape is not limited, and a spring such as a coil spring having excellent durability as shown in FIG. 3 may be used, and the elasticity adjustment by the adjustment mechanism 13 can be performed accurately.

  In the above mechanism, by operating the vibrator 1 in the state of FIG. 1, vibration is applied to the whole body of the user via the diaphragm 2 and the wheelchair 6. At this time, due to the upward elasticity of the elastic body 11, Vibration in the upward direction is assisted, and the load on the vibrator 1 is reduced by the assisted energy (electric power).

According to the inventor's experiment, when the support device 12 is removed using the rated vibrator 1, when a person with a weight of about 64 kg is placed, 30 W of power is required. When inserted in the four corners, an output of 23 W is sufficient, and a power saving effect of about 23% was obtained.
From this, it is clear that a significant power saving effect can be obtained by the support device 12 in the device of the present invention.

FIG. 3 is a front view of a second embodiment shown as an apparatus for nursing care that uses a coil spring as the elastic body 11 and performs bathing and other assistance for a person who has difficulty walking such as a handicapped person.
In this example, the vibrator 1 is disposed on a suspension device 18 that is suspended on a rail 15 disposed on a ceiling 14 in a building via a suspension unit 16 and a pulley 17 so as to be movable.

  An upper end of a U-shaped frame 19 is pivotally supported by a lower end of the hanging portion 16 by a fulcrum shaft 21, and a platform 22 supported horizontally in a suspended state at the lower end of the frame 19. Is provided.

  The grounding base 3, the vibrator 1, and the diaphragm 2 are sequentially stacked or mounted and fixed on the mounting base 22, and the support devices 12 are provided at the four corners between the diaphragm 2 and the grounding base 3. Is provided. In this example, the vibrator 1 can be directly attached to the mounting base 22 and can also be used as a grounding base.

  In this embodiment, a user who is difficult to walk can be seated on the diaphragm 2 or can be laid down with a bed (not shown) placed thereon, and vibration can be applied. It is possible to use such as bathing in a tilted state. The operation as the vibration applying device is the same as the above example.

  In the above embodiment, the vibrator 1 is provided on the mount 22 of the frame 19 for suspension. However, the vibrator 1 is interposed between the frame 19 and the ceiling 14 to impart vibration to the entire frame 19. It is also possible to adopt a configuration. In this case, a structure in which the suspension load of the frame 19 is applied to the diaphragm 2 side, and an upward elastic assist is given to the diaphragm 2, and the lower side of the vibrator 1 in FIGS. For example, it is necessary to suspend and support the grounding base 3) of FIGS. 1 and 2 on the ceiling 14 side, and the user places it on the platform 22. In this case, the ceiling 14 side serves as a support portion, and the vibration load direction varies depending on the vertical direction of the vibrator 1, so that the direction of action of the elastic body 11 such as a spring may be upside down.

  FIG. 4 shows a third embodiment of the present invention. In this example, the diaphragm 2 is separated from the vibrator 1, and the vibrator 1 arranged on the floor surface 4 is straddled across or above the vibrator 1. It arrange | positions in the state which earth | grounded the support apparatus 12 so that it might cover. The support device 12 is attached to the bottom surface of the four corners of the diaphragm 2 so as to project the adjustment mechanism 13 downward, and the elastic member 11 made of rubber or foamed plastic is attached to the lower end of the adjustment mechanism 13. Grounded.

  In the above arrangement, the bottom surface of the diaphragm 2 and the top surface of the vibrator 1 are not in contact with each other in an unloaded state, leaving a gap ΔH, and when the user rests on the diaphragm 2, the elastic body 11 is elastically deformed by compression. The diaphragm 2 comes into contact with the upper surface of the vibrator 1, and the diaphragm 2 vibrates by the vibrator 1.

Since it is configured as described above, in this example, the vibrator 1 and the diaphragm 2 can be stored and carried separately, and the size and the like of the diaphragm 2 can be appropriately selected according to the use and purpose. There is an advantage that, when a person or a wheelchair gets on and off the plate 2, or when only a foot is placed on the plate 2 to receive vibrations, the vibration due to tilting does not occur even when a biased load is applied to the diaphragm 2.
In this example as well, in the same way as in the first and second embodiments, the load on the vibrator can be reduced by the upward elastic force acting by the elastic body 11 when the vibration is applied.

  In any of the above embodiments, it is possible to use a rubber-male-like hollow body or an air cushion (not shown) having a structure in which air is enclosed in a cylinder and the piston is moved up and down as the elastic body 11.

  As described above, in the present invention, the elastic body 11 may act in the pushing-opening direction in the apparatus used by being placed on the floor surface shown in FIGS. However, in the case of a suspension type device, the elastic body 11 when suspended via the vibrator 1 is elastic in the tension direction, and therefore, when using a spring, a tension spring may be used. Further, when rubber or plastic material is used as the elastic body 11 in this case, it is assumed that a stretchable string, rope or belt shape is used.
