Description

  The present invention relates to a vibratory massager that massages by propagating vibrations to the human body, and is suitable for massaging the back, shoulders, buttocks, soles, calves and the like of the human body.

  As shown in Patent Document 1 and the like, the conventional vibratory massager has a motor 11 ′ and an eccentric plate 12 ′ that function as vibration generating means 10 ′ and vibration generated by the vibration generating means 10 ′. (See FIG. 11).

  And although the diaphragm 30 of patent document 1 has many small protrusions 31 on the surface, the shape of the diaphragm 30 whole is a plate shape. Therefore, although there is no specific description in Patent Document 1, it is general to adopt a solid (solid) resin injection molded product that does not have a gap inside the material for the conventional vibration propagation means.

Utility Model Registration No. 3102701

  However, in the conventional vibration propagation means 30 in which the solid resin injection molded product is adopted in this way, as illustrated in FIG. 4A, the vibration from the vibration generation means 10 ′ is applied to the body massage surface ( Since it is not so diffused in the direction (left and right direction in FIG. 4) along the contact surface with the vibration propagation means of the human body (the back surface of the foot in the example of FIG. 4), the portion close to the vibration generating means 10 ′ in the massage surface (FIG. 4), the vibration was propagated locally. Therefore, the local stimulation is too strong for the massage surface of the body, and in some cases, the body may become locally painful. And simply, if the vibration generated by the vibration generating means 10 'is weakened, the pain can be avoided, but the comfort due to the massage effect is lost.

  In view of the above points, the present invention aims to achieve both the suppression of locally damaging the massage surface of the body and the reduction of the massage effect, and the creation of an unprecedented new feeling of comfort. The purpose is to provide a new massager.

  In order to achieve the above object, according to the first aspect of the present invention, there is provided a vibration generating means for generating vibration and a vibration propagation means for propagating the vibration generated by the vibration generating means to a human body, wherein the vibration propagation means is random. It is characterized in that it is a network structure having a predetermined bulk density of voids formed by contact-entangled assembly of a plurality of resin continuous filament elastic bodies formed in a loop or curl.

  In the invention according to claim 2, the vibration propagation means has a laminated structure including an inner layer in which the bulk density of the network structure is set low and a surface layer in which the bulk density is set higher than the inner layer. The vibration propagation means is arranged so that the lamination direction of the laminated structure is parallel to a direction from the vibration generation means toward the human body. Furthermore, the invention according to claim 3 is characterized in that the surface layer is disposed on both front and back surfaces of the inner layer.

The bulk density of the surface layer is preferably 0.2 to 0.5 g / cm ³ (more preferably 0.3 to 0.4 g / cm ³ ). The porosity of the surface layer is preferably 44 to 77% (more preferably 56 to 67%). The inner layer preferably has a bulk density of 0.01 to 0.15 g / cm ³ (more preferably 0.03 to 0.05 g / cm ³ ). The porosity of the inner layer is preferably 83 to 99% (more preferably 94 to 97%).

  According to the first aspect of the present invention, the vibration from the vibration generating means is effectively diffused in the direction along the body massage surface by the vibration propagation means, and as illustrated in FIG. The vibration is propagated uniformly. Therefore, it can suppress that the massage surface of a body becomes locally painful without causing the massage effect reduction by weakening the vibration by a vibration generation means.

  By the way, the feeling of feeling experienced by massage is not a property that can be measured by physical quantities such as vibration frequency, amplitude, vibration intensity, blood pressure, and body temperature that can be measured on the massage surface. That is, in addition to these physical quantities, the degree of comfort and the kind of comfort that humans feel can be felt differently depending on the form of massage.

  The present invention has been made in view of such a “feeling of comfort by massage”, and that the vibration propagation means has the network structure according to claim 1 is an extension of the development of the conventional vibratory massager. It is not something that exists, but its massage form is completely different. Therefore, the vibratory massager according to the present invention creates an unprecedented new feeling (feeling like being worn), and in fact, many of the vibratory massagers according to the present invention have been experienced. The effects of the present invention have been proven by the test subjects who talked about their comfort.

  The key to the present invention is a vibration propagation means having a net-like structure. For example, it can be easily manufactured by extruding a thermoplastic resin such as polyethylene or polypropylene and performing thermal fusion while looping or curling. . Further, when the extrusion process is performed in the extrusion process, the effect of the present invention is further enhanced. Further, the vibration propagation means according to the present invention is required to have resistance to repeated stress (no sag) and an elastic force greater than a predetermined value. According to the vibration propagation means according to the above manufacturing method, the above-mentioned requirement can be sufficiently satisfied as compared with, for example, urethane foam or the like.

  According to invention of Claim 2, the function of the vibration propagation means, such as diffusing vibration in the direction along the massage surface, is more effectively exhibited, and the above-described effect that vibration is uniformly propagated to the massage surface. Will improve. And according to invention of Claim 3, the said effect improves further.

For this purpose, a hole 20b is formed.

  The hole 20b is formed by a male mold having a press surface having the same shape as the outer shape of the contact portion 13, and is formed by hot pressing the surface of the mesh spring structure 20 at an arbitrary angle. The angle is not necessarily perpendicular to the mesh spring structure 20, the angle may be changed according to the application, and the number of installations is arbitrary.

  In the pressing step, the surface layers 23 and 24 having a high bulk density are maintained as they are on the bottom surface in the pressing direction of the hole 20b, and the side surface of the hole 20b is pressed by the linear elastic body 21 of the mesh spring structure 20 by pressing.

  By the way, according to the massage device of the conventional structure, the vibration propagated to the massage surface of the human body vibrates in the same direction as the main vibration direction by the vibration source (the direction indicated by the arrow R in the example of FIG. 4A). Therefore, the bodily sensation of massage becomes a uniform feeling. On the other hand, according to the vibration type massage device 1 of the present embodiment, the direction of the vibration becomes irregular in the process in which the vibration is propagated in the reticulated spring structure 20, so that the conventional uniform feeling It is possible to create a new feeling that is different from that of the past.

In the reticulated spring structure 20, the linear elastic body 21 of the linear aggregate 113 is randomly formed in a loop shape, the loops are partially intertwined and welded to be solidified in water, and the winding roll 129. , 129 is taken out as a reticulated spring structure 20.

  As shown in FIG. 6, when it is difficult to bend the reticulated spring structure 20 that is a three-dimensional structure with the take-up rolls 125, 125 at the time of take-up, it is bent at that portion by forming a portion with a coarse bulk density. It can also be raised from. The cutting device 130 cuts the extracted reticulated spring structure 20 to an appropriate length. The loop forming apparatus 150 narrows down the thickness of the continuous continuous line elastic body 21 discharged from the mold 122 before the continuous line on the outer peripheral side surface touches the water surface of the water tank 126 to reticulate the spring structure 20. In addition to increasing the density of the surface layer of the belt, the loops are formed smoothly so that the fusion between the loops is made uniform. Further, before the endless belt 128 of the conveyor is touched, the surface is cooled and solidified to engage the belt 128. It prevents the marks from sticking to the product.

[Method for Manufacturing Reticulated Spring Structure 20]
Next, an example of a method for manufacturing the mesh spring structure 20 will be described.

  As shown in the schematic diagram of FIG. 8, in the method for manufacturing the reticulated spring structure 20 in the present embodiment, preferably, a polyolefin resin such as PE or PP and a raw material resin such as VAC, EVA or SBS are described later. The mixture is dry-blended via a tumbler or a fixed-volume feeder, or mixed or melt-mixed to be pelletized, and sent to the hopper 121 of the extruder 120.

  Specifically, a raw material resin, for example, PP and SBS are mixed with a tumbler (KR mixer manufactured by Kato Riki Seisakusho) at 40 rpm for 15 minutes.

  Next, as shown in the explanatory diagram of FIG. 5, the mixture made of the raw material resin is introduced from the hopper 121 (see FIG. 6) of the φ65 mm single screw extruder 120 and melted at a predetermined temperature (200 ° C. to 260 ° C.). The mixture is kneaded and melt-extruded from a large number of nozzles having a predetermined diameter provided on the forming die 122 at a predetermined extrusion speed, and taken out by a take-out device 124, whereby a predetermined wire diameter (for example, 600 to 90,000 denier, preferably 3,000 to 30,000 denier, more preferably 6,000 to 10,000 denier), and the melted filament elastic bodies 21 are joined together by the loop forming device 150. Random loops, for example, loops having a diameter of 1 to 10 mm, preferably a diameter of 1 to 5 mm, are formed by tangling the adjacent linear elastic bodies 21 with each other. At this time, at least a part of the contact entanglement site is melt-bonded to each other and cooled. Further, dense surface layers 23 and 24 and a sparse inner layer 22 are formed. As for the linear elastic body 21, a hollow thing and a solid thing may be mixed by the predetermined ratio.

  The thickness and bulk density of the three-dimensional structure which is a set of random loops are set between the take-up rolls 125 and 125 of the take-up machine 124 in the water tank 126. This three-dimensional structure (for example, a thickness of 10 to 200 mm and a width of 2,000 mm) is randomly formed into a curl or loop shape, solidified in water, and taken out as a reticulated spring structure 20 by winding rolls 129 and 129. .

When the linear elastic body 21 in which this loop is formed in water is pulled by the puller 124, the three-dimensional network characteristics may be changed by changing the speed of the puller 124. The bulk density of the reticulated spring structure 20 is 0.001 to 0.20 g / cm ³ , preferably 0.08 to 0.20 g / cm ³ , particularly 0.10 to 0.18 g / cm ³ , and the porosity 78 -91%, preferably 80-88%. Bulk density 0.2-0.5 g / cm ³ of the surface layers 23 and 24, preferably, 0.3~0.4g / cm ^3, the porosity is 44-77%, preferably 56-67%, The bulk density of the inner layer 22 is 0.01 to 0.15 g / cm ³ , preferably 0.03 to 0.05 g / cm ³ , and the porosity is 83 to 99%, preferably 94 to 97%.

  For example, the take-up speed of the take-up rolls 124 is adjusted to a low speed at a predetermined interval (for example, 3 to 5 m), for example, the take-up speed of the take-up rolls 125, 125 is set to a low speed within a set time every set time by a timer. Thus, in the longitudinal direction of the reticulated spring structure 20, a portion having a large bulk density formed at low speed take-up at every predetermined interval (for example, 30 to 50 cm) and a portion other than that, that is, a density is continuously formed. Also good.

  As shown in the front view of FIG. 6, when it is difficult to bend the reticulated spring structure 20, which is a three-dimensional structure, with the take-up rolls 125, 125 at the time of take-up, the part with a coarse bulk density is formed at that part. Can be bent and pulled up from the water. The reticulated spring structure 20 taken out through the above steps is appropriately cut to a length by the cutting device 130.

As an example, a reticulated spring structure 20 having a bulk density of 0.03 g / cm ³ and a thickness of 50 mm was obtained by the above manufacturing method. In addition, a three-dimensional structure can also be manufactured using what consists of a combination of 1 type or several types of different materials, respectively.

  A method for forming the hole 20b will be described. The hole 20b may be formed by mechanical deletion with a cutter or the like. However, since chatter noise may occur, in order to prevent this, the mesh body may be melted and solidified by pressing the mesh body downward from above with a hot press (for example, 100 ° C.).
