The acupressure rod moving treatment device comprising an acupressure rod (7) that can be inserted into the acupuncture rod insertion hole (3). ”, The acupressure rod is inserted and attached to the acupressure rod insertion hole. Fine adjustment of the mounting position was difficult. In addition, since there is only one acupressure rod in the horizontal and lateral directions, it is difficult to apply them simultaneously to the inside of a pair of scapulas present in the shoulder width direction, for example. Furthermore, the acupressure rod is simply configured to be inserted and attached to the acupressure rod insertion hole, and the acupressure rod is only supported by the plate thickness portion of the treatment device body forming the acupressure rod insertion hole, and is unstable. there were.
Patent Document 2 states that, as described in the claims, “... the base is composed of a main body and a movable portion that is slidable along the upper surface of the main body, and is orthogonal to the sliding direction of the movable portion on the upper surface of the movable portion. A tweezer characterized in that two protrusions lined up at predetermined intervals in the direction to be attached are detachably attached, and a plurality of protrusions having different heights are prepared. " However, it is difficult to stably fix the protrusions. There was a possibility that the protruding portion was displaced during use. In addition, since the slidable movable part can only be moved and adjusted in one direction, it is impossible to adjust the position in the height direction (height direction) of the user even if the movement of the protrusion can be adjusted in one direction in the shoulder width direction. It was. Furthermore, the acupressure device of Patent Document 2 is a type that the user lays on his back on the floor after placing it on the floor or the like, and for example, it is difficult to use it while standing on the back in a sitting position. .

  The present invention solves the above-described problem, and can press the position of the pressing protrusion not only in the user's shoulder width direction but also in the height direction, and can hold the finely adjusted protrusion firmly at that position.

FIG. 9 shows a perspective view of a chair incorporating the pressing device of FIG. 8 as a back plate. Each drawing is simplified for easy understanding of the drawings, and the components not directly related to the present invention are omitted. The protrusion 6 in FIG.

The pressing device 1 includes a substrate 2 and a protrusion 5 as shown in FIGS. The substrate 2 is provided with a plurality of holes 4 penetrating or recessed from one plate surface 3a to the other plate surface 3b with the same shape and spaced apart from each other.
The protrusion 5 has a pressing protrusion 6 formed on the distal end side, and a protrusion 7 that fits into the hole 4 on the proximal end side and is detachably inserted into the hole 4. The bottom surface 60 of the pressing projection 6 is set larger than the opening 40 of the hole 4 (FIG. 2). Here, the protrusion 6 has a three-dimensional shape in which a conical tip portion 62 having a round top is extended on the upper surface of the cylindrical body as the main portion 61, and the top of the protrusion 6 is easily pressed against the trigger point. . The trigger point is a hardened part of the muscle that is hardened. Most of the symptoms such as stiff shoulders and pain are attributed to this trigger point. A pair of protrusions 5 is a presser 1 in which at least one set is prepared.

A plurality of holes 4 are provided in the shape of a regular polygon in plan view, and are provided vertically and horizontally on one plate surface 3 a of the plate body 3 related to the substrate 2. Let the convex part 7 fitted to the hole 4 be a regular polygonal column part. A regular polygon is a polygon whose sides are all equal and whose inner angles are all equal. It is preferable that a plurality of rows of holes 4 are provided symmetrically in the left-right direction and a plurality of stages are provided in the vertical direction while the substrate 2 is standing. There are many trigger points in the human body. The human body is almost symmetrical, but the shoulder width is different and the height is also different. Therefore, in the substantially square plate-like substrate 2 of FIG. 1, holes 4 are provided in the lateral direction of the plate surface in three rows symmetrically about the central vertical center, and the vertical direction is inside the vertical center. There are 3 steps near the upper edge 37, 5 steps on the outer side, and 6 steps on the outermost side along both side edges 39 from the upper edge 37 to the lower edge 39. For people with different body sizes and body shapes I am trying to respond.
Further, the central axis 7 c of the convex portion 7 passes through a point decentered from the center 60 c of the bottom surface of the pressing projection 6 toward the peripheral edge, and the convex portion 7 is formed to project from a part of the bottom surface 60. Therefore, the side surface 75 related to the convex portion 7 of the regular polygonal column portion can be changed and fitted into the hole 4 having a polygonal shape in plan view by the number of sides thereof. When the side surface 75 of the convex portion 7 is sequentially changed and fitted to one specified side of the hole 4, the central axis 7 c of the convex portion 7 forms a point 60 p that is decentered from the center 60 c of the bottom surface of the protruding portion 6. Since it passes (FIG. 3), the location of the projection 6 on the substrate 2 can be changed to a predetermined position finely adjusted. In addition, the plan view polygon referred to in the present invention allows the corner 4 to be rounded as shown in FIG. Similarly, the regular polygonal column portion also allows the corner portion to be rounded as shown in FIG.

The hole 4 is a concave hole 41 that is recessed from one plate surface 3a to another plate surface 3b as shown in FIG. 2 (b), and from one plate surface 3a to another plate as shown in FIG. 2 (b). It may be a through hole 42 penetrating toward the surface 3b. However, the ease of making the through hole 42 and the contact height of the inner wall portion 31 when the convex portion 7 is inserted into the concave hole 41 even if the plate body 3 of the substrate 2 has the same thickness 3t. However, as compared with the inner wall portion 32 in the case of the through hole 42, it becomes shorter by the formation of the bottom of the concave hole, and the insertion integration is somewhat weakened. Therefore, the through hole 42 is more preferable.
In the present embodiment, the hole 4 is a square through hole 42a that is easier to produce, and the convex part 7 is a regular square column part 72a that is easier to produce as shown in FIGS. The height 7h of the regular quadrangular column 72a is substantially matched to the thickness 3t of the board body 3 of the substrate, in other words, the depth of the through hole 42. By inserting the projection 7 into the through hole 42, the bottom surface 60 of the projection 6 around the projection 7 comes into contact with the plate surface 3 a of the substrate 2, and the projection 6 is stably placed on the substrate 2. The
In addition, a hook-shaped small protrusion 8 is formed to protrude from one side wall surface 75 of the convex portion 7. By inserting the convex portion 7 into the through hole 42, the small protrusion 8 is crimped to the inner wall portion 32 that forms the through hole 42. When the convex portion 7 is inserted into the through hole 42, the small protrusion 8 is pressed against the inner wall portion 32, thereby preventing the protrusion 5 from falling off the substrate 2.

  FIGS. 4A to 4D show the movement of the bottom surface 60 of the protrusion 6 according to the protrusion 5 in which the protrusion 7 is inserted into the through hole 42. The center axis 7c of the convex portion 7 is eccentric as described above from the center 60c of the bottom surface of the protruding portion 6. When the substrate 2 having the square-shaped through holes 42a and the protrusions 5 having the convex portions 7 of the regular quadrangular prism portions 72a are formed, one of the plurality of through holes 42 formed in the substrate 2 is used. Even if it exists, the position of the projection part 6 can be slightly moved to four directions like FIG. 4 by changing and inserting the side surface 75 of the convex part 7 into the inner wall part 32 one by one. 4 shows the peripheral edge 69 of the bottom surface 60 so that the movement of the bottom surface position of the protrusion 6 can be easily understood, FIG. 4 (a) is a solid line, FIG. 4 (b) is a dotted line, FIG. FIG. 4D is drawn with a two-dot chain line.

  Specifically, in FIG. 4 (a), the bottom surface 60 of the projecting portion, in which the projection 7 is inserted with the small projection 8 on the top of the figure, is arranged so as to be entirely shifted to the upper right side of the drawing with respect to the through hole 42. 4B, the projection bottom surface 60 with the projections 7 inserted with the small projections 8 on the left in FIG. 4A is arranged so as to be entirely shifted to the lower left side of the drawing with respect to the through holes 42. Similarly, in FIG. 4C, the projections bottom surface 60 is arranged so as to be shifted obliquely downward to the right of the drawing with respect to the through-hole 42 with the small projections 8 at the bottom, and FIG. 8 is set to the right in the figure, and the protrusion bottom surface 60 is arranged so as to be shifted obliquely upward to the right of the drawing with respect to the through hole 42. Thus, even if one convex portion 7 is inserted into the same through hole 42 in the substrate 2, the projection 75 can be formed by changing the side surface 75 of the convex portion 7 facing the one inner wall portion 32 that forms the through hole 42. The arrangement of the portion 6 is a pressing device 1 that slightly changes in the vertical and horizontal directions on the paper surface on the substrate 2 in FIG. Solid lines, dotted lines, alternate long and short dash lines, and alternate long and two short dashes lines in the bottom edge 69 in FIG. 5 correspond to (a), (b), (c), and (d) in FIG.

Assuming that the through hole 42a has a square shape in plan view and the convex portion 72a of the regular quadrangular column portion, even when the one through hole 42 is a fixed point on the substrate 2, the protruding portion 6 when the convex portion 7 is attached thereto. Can be moved to four locations as shown in FIGS. Therefore, the user of the present pressing device 1 can finely adjust the arrangement of the protrusions 6 in the through holes 42 in the substrate 2 as appropriate.
Similarly, when the front view is a regular triangular, regular pentagonal, regular hexagonal,... Through-hole 42 and the convex part 7 is a regular triangular prism part, regular pentagonal column part, regular hexagonal column part,. The protrusion 6 when the convex part 7 is inserted at the fixed point can be set by moving it to three, five, six,. However, from the viewpoint of ease of production, cost, and the like, it is more preferable that the through hole 42a has a square shape in plan view and the convex portion 72a has a regular quadrangular prism portion.
Moreover, although the board | substrate 2 and the protrusion 5 which comprise the presser 1 may be plastics etc., a wooden thing is more preferable. By using the wooden substrate 2 and the wooden projection 5, the warmth and fragrance of wood and the elasticity and flexibility peculiar to wood are provided. When the projection 7 is inserted into the through hole 42, the small projection 8 is formed. This is because the protrusion 5 can be held on the substrate 2 by moderate pressure bonding to the inner wall portion where the through hole 42 is formed.

On the other hand, the protrusion 5 in which the protrusion 7 is inserted into the through hole 42 of the substrate 2 may be pulled out by holding the protrusion 6 in the hand, but for example, the front end surface of the protrusion 7 inserted into the through hole 42. The protrusion 5 can be easily removed from the through-hole 42 by pressing 76 with the force exceeding the force by which the small protrusion 8 is crimped to the inner wall surface of the through-hole 42. And the convex part 7 can be inserted in the through-hole 42 of the new position of the board | substrate 2, and the projection body 5 can be set to the location of the board | substrate 2 suitable for each user.
The pusher 1 has a size that can be easily carried as shown in FIGS. 1 and 5, and can be used by one person according to his / her own pace regardless of place or time.

FIGS. 6 and 7 show another embodiment of the protrusion 5 in place of the protrusion 5 shown in FIGS. The pair of protrusions 5 in FIG. 6 have the same protrusions 7 as the protrusions 7 of the protrusions 5 in FIGS. 1 to 5, but the protrusions 6 are semicircular as shown. It has a shape suitable for pressing the projection 6 on the inside of both shoulder blades. Each of the pair of protrusions 5 in FIG. 7 has a shape in which the protrusion 7 is matched with the protrusion 7 of the protrusion 5 in FIGS. 1 to 5, and the protrusion 6 is a semi-cylindrical body as illustrated. The shape is suitable for pressing around the waist. In addition to the pair of protrusions 5 shown in FIGS. 1 to 5, the pressing device 1 having the pair of protrusions 5 shown in FIGS. 6 and 7 is suitable and effective for the trigger point of each part in the body. It becomes possible to press it automatically.
FIG. 8 shows the pressing device 1 in which the protrusions 5 of FIG. 6 are inserted into the through holes 42 of the substrate 2 of another embodiment instead of the substrate 2 of FIGS. People are different in height and body shape. As shown in the drawing, when the vertically long substrate 2 is in the standing state, the through holes 42 are provided in a plurality of rows symmetrically in the left-right direction and in a plurality of stages in the vertical direction, so that a plurality of trigger points suitable for each person can be provided throughout the whole body. The part can be pressed simultaneously.
The other structure is the same as that of the presser 1 of FIGS. 1-5, and the description is omitted. 6 to 8, the same reference numerals as those in FIGS. 1 to 5 denote the same or corresponding parts.

  FIG. 9 shows a chair CR in which a back plate R1 is formed on the substrate 2 of the presser 1 of FIG. When the back plate R1 of the chair CR is formed by the substrate 2 of the presser 1 according to the present invention as shown in the figure, when the protrusion 5 is inserted and fixed at a desired position and sitting on the chair CR in daily life, By simply putting the weight on the back plate R1, it is possible to press the trigger point and the associated pain site. During work or a break while sitting on the chair CR, if you keep pressing for a few minutes in a comfortable posture, you can relax muscle stiffness. The chair CR of FIG. 9 forms a plurality of square through holes 42a having a square shape in plan view in which the convex portions 7 including the regular quadrangular column portions 72a of the protrusions 5 can be inserted not only in the back plate R1 but also in the seat portion R3 and the armrest R4. . The protrusions 5 can be used to press not only the region from the back to the waist but also the trigger points around the buttocks, the arms, and related pain regions. In FIG. 9, reference symbol R2 is a leg, reference symbols R5 and R6 are horizontal members, reference symbol R7 is a seat receiving member, R8 is a locking tool, and R9 is a locking member for horizontal members R5 and R6 that also serve as a through hole 42. Indicates a hole.

Since the pressing device 1 configured in this manner can accurately press the protrusion 6 on the trigger point or the related pain site, the pressure is pressed for 10 seconds with a strength that feels comfortable pain at the trigger point, and then 5 seconds. Excellent effect for relaxing muscle stiffness in self-treatment methods such as "Ischemic compression method" that repeats opening and "Counter strain method" that maintains the appropriate relaxed state of muscle for 90 seconds by pressing Demonstrate.
Muscle stiffness is attributed to the stagnation of lymph containing waste products such as lactic acid and fat accumulated in the muscles, joints and surrounding parts. Originally, by using muscles by themselves, the lymph fluid containing waste products is sent to the lymph nodes at each site in the direction of the heart, and the lymph fluid filtered in the lymph nodes to the junction with the vein near the clavicle, The remaining waste is sent to the kidneys. And waste products are discharged out of the body as urine.
However, if you do not move the muscles, or if you keep them stretched or stretched, you will not be able to use the muscles as described above, so there are proteins and capillaries between your muscles, joints, and surrounding parts such as capillaries. Lymph containing fat stays. It expands in the direction of muscle contraction and relaxation, restricting the movement of muscles and joints, and eventually causes pain and chronic pain.
In the pressing device 1 of the present invention, a regular polygonal hole 4 in plan view is provided in the substrate 2, while a convex portion 7 of a regular polygonal column part that fits into the hole 4 is formed in the protrusion 5, and the bottom surface 60 of the protrusion is formed. Since the central axis 7c of the convex portion 7 passes through the point 60p that is decentered from the center 60c to the peripheral edge 69 side, the convex portion 7 can be inserted even if the convex portion 7 is inserted into one hole 4 in the substrate 2. The arrangement of the protrusions 6 on the substrate 2 can be moved as shown in FIGS.
If the holes 4 are simply a regular polygon in plan view, even if a plurality of holes 4 are provided vertically and horizontally on the substrate plate surface 3a, there is a problem in the case where it is desired to install the protrusions 6 between the holes 4 that are separated from each other. However, in the pressing device 1 of the present invention, when the protrusions 6 are close to each other in the hole 4, the side surface 75 of the convex portion 7 is sequentially replaced and fitted to the one specified side as shown in FIG. (B) Since the arrangement of the projections 6 on the substrate 2 can be finely adjusted as in (d) to (d), unlike the invention of Patent Document 1, the target point such as a trigger point or a related pain site is excluded. The protrusions 6 can be pressed together.
A plurality of holes 4 are provided vertically and horizontally on one plate surface 3a of the substrate 2, and the center axis 7c of the convex portion 7 passes through a point 60p that is decentered from the bottom surface center 60c of the protrusion 6 toward the peripheral edge 69. Thus, even if the convex portion 7 is inserted into one hole 4 as described above, the arrangement of the protrusions 6 can be slightly changed around the hole 4 (FIGS. 4 and 5). Furthermore, although Patent Document 2 could not be adjusted in the height direction even if it can be adjusted in the user's shoulder width direction, the pressing protrusion 6 can be finely adjusted not only in the user's shoulder width direction but also in the height direction, It is excellent in that the projection 6 can be reliably applied to the necessary trigger points required by each user.

And since the convex part 7 of the regular polygonal column part is fitted and inserted into the hole 4 having the same shape of the regular polygon in plan view, even if the body is moved or twisted, the protruding part 6 is inadvertently placed sideways. Does not shift. Unlike inserting the cylindrical part into the circular hole, there is no problem that the protruding part 6 rotates. The protrusion 6 after being attached to the through hole 42 of the substrate 2 is securely held by the substrate 2 without being displaced, and moreover, in addition to the supine state, if the small protrusion 8 is provided, it can be used in the sitting position. Yes.
Muscle stiffness is said to relax by continuing to press the trigger point or associated pain site for 90 seconds. Since the convex portion 7 of the regular polygonal column portion is fitted into the hole 4 having the same shape of the regular polygon in plan view, the position of the convex portion 7, that is, the protruding portion, even if the body is shaken when pressed. The position of 6 does not change, and it can be surely kept pressed for 90 seconds or more on the trigger point or related pain site.

  Further, when the hole 4 is the through hole 42, the manufacture is facilitated. Further, even in the protrusion 5 in which the small protrusion 8 is provided on the convex portion 7, the small protrusion 8 faces the convex portion 7 inserted into the through hole 42 with the tip surface 76 facing the protrusion 6. The protrusion 5 can be easily removed from the through-hole 42 by pushing beyond the pressure-bonding force to the inner wall. The protrusion 5 can be easily attached to and removed from the substrate 2 by a human hand.

Further, when the convex portion 7 of the regular polygonal column portion is inserted into the regular polygonal through hole 42, each corner portion of the regular polygonal column portion is fitted to each inner corner of the regular polygon. The movement of the part 7 is stopped, and the fitting and integration of the two is ensured. In particular, it has a structure suitable for hitting the pressing device 1 which must continue to press firmly to the trigger point. The pressing device 1 can hold the finely adjusted protrusion 6 firmly at a predetermined position on the substrate 2.
Further, if the hole 4 is a square through hole 42a that penetrates from one plate surface 3a to the other plate surface 3b, and the convex portion 7 is a regular quadrangular prism portion 72a, the manufacturing is further facilitated. The cost can be reduced.

In addition to the protrusions 5 shown in FIG. 1, when a plurality of sets of protrusions 5 having different shapes of the protrusions 6 shown in FIGS. The body 5 can be selected. The selected protrusion 5 can be easily inserted and set to a desired position on the substrate 2 while being finely adjusted by one user. After that, only the body weight is applied, and the desired pressing device 1 that exhibits a pressing effect in a short time from the back of the head to the sole of the foot is obtained.
As described above, a suitable pressing projection 6 can be disposed at the set position of the substrate 2 required by the user, and the position of the pressing projection 6 can be finely adjusted not only in the shoulder width direction of the user but also in the height direction. It is extremely useful that it can be adjusted and arranged well, and the projection 6 set at the optimum position of the finely adjusted substrate can be firmly held.

  The present invention is not limited to those shown in the above-described embodiment, and various modifications can be made within the scope of the present invention depending on the purpose and application. The shape, size, number, material, material, etc. of the substrate 2, the hole 4, the through-hole 42, the protrusion 5, the protrusion 6, the protrusion 7, and the small protrusion 8 can be appropriately selected according to the application. For example, the substrate 1 illustrated in the embodiment and the protrusions 6 illustrated in FIGS. 1 to 7 are examples, and other substrates and protrusions can be employed.
