Description

  The present invention relates to a training device for enhancing the mobility of the entire arm.

  As a training device, a training device that can easily perform training of the entire arm is known (for example, see Patent Document 1).

This is generally composed of a sphere. A pair of palm-sized rotating plates (massage plates) are provided on the surface at symmetrical positions with respect to the center of the sphere. The user rotates the rotating plates alternately in the right direction and the left direction with the left palm applied to one rotating plate and the right palm applied to the other rotating plate. As a result, the left and right wrists rotate and move with reference to the rotation center of the rotating plate, and accordingly, the entire arm from the wrist to the shoulder is moved, thereby training the entire arm.
Registered Utility Model No. 3096582

  However, since the above-mentioned Patent Document 1 is a multi-function machine capable of performing other training, there is a problem that the operability is inferior because the configuration is complicated and the weight is heavy.

  In addition, there is a problem that training of the entire arm from the wrist to the shoulder is not always sufficient. That is, the thing of patent document 1 is formed in the substantially spherical body as a whole, and the two rotary plates are arrange | positioned by the distance corresponding to the diameter of a spherical body. For this reason, when the left and right palms are respectively applied to the two rotating plates, there is little difference between the distance between the left and right palms and the shoulder width, so the wrist is less bent with respect to the forearm and the palm is against the forearm. Line up on a straight line. In this state, when the two rotating plates are rotated by the left and right palms, the forearm and the entire arm movement is small relative to the palm movement. For this reason, the training of the whole arm becomes insufficient.

  Accordingly, an object of the present invention is to provide a training device that has a simple configuration and is excellent in operability during training and that can sufficiently train the entire arm.

  According to a first aspect of the present invention, in the training device, a pair of plates opposed to each other via a gap, and a holder that is interposed between the pair of plates and rotatably supports the pair of plates. The pair of plates has an inner surface facing each other through a gap and an outer surface on which a user's palm is placed.

  According to a second aspect of the present invention, in the training device according to the first aspect, the inner side surface is formed in a flat shape, and the outer side surface is formed in a spherical shape.

  According to a third aspect of the present invention, in the training device according to the first or second aspect, the holder is constituted by a rolling bearing.

  According to a fourth aspect of the present invention, in the training device according to any one of the first to third aspects, an anti-slip is formed on the outer surface.

  According to a fifth aspect of the present invention, in the training device according to any one of the first to fourth aspects, the plate has a hollow portion.

  According to a sixth aspect of the present invention, in the training device according to the fifth aspect, a fluid is injected into the hollow portion.

  According to the first aspect of the invention, the distance between the left palm applied to the outer surface of one plate and the right palm applied to the outer surface of the other plate can be reduced, so that both plates are rotated. Thus, the wrist can be bent or stretched, or the arm can be rotated around the elbow or shoulder to make a large three-dimensional movement. Therefore, the movement of the entire arm can be increased. In addition, unlike a multifunction machine, no extra parts or the like are incorporated, so that it is possible to provide a simple configuration and excellent operability.

  According to the invention of claim 2, since the inner side surface of the plate is formed in a flat shape, the distance between the pair of plates can be made closer, so that the user can move the left side to the outer side surface of one plate. When training with the right palm on the outer surface of the other plate, the distance between the left and right palms can be made closer. As a result, the same effect as in the first aspect can be obtained. Moreover, since the shape of the outer surface of the plate is formed in a spherical shape close to the natural shape of the palm in a state where the force is removed, operability can be improved.

  According to invention of Claim 3, since the holder is comprised by the rolling bearing, the relative rotation operation | movement of a pair of plate can be made very smooth.

  According to the fourth aspect of the present invention, the slipping of the palm with respect to the outer surface of the plate can be suppressed by the anti-slip, so that the operability during training can be improved.

  According to the invention of claim 5, by providing the hollow portion, the weight of the plate can be reduced, and the operability can be improved accordingly.

  According to the invention of claim 6, by injecting the fluid into the hollow portion, the user can experience an unexpected force as compared with the case where the fluid is not injected. Further, since the weight can be adjusted by adjusting the type and injection amount of the fluid, an appropriate load can be easily set according to the user.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, what attached | subjected the same code | symbol in each drawing has the same structure or effect | action, The duplication description about these was abbreviate | omitted suitably.
<Embodiment 1>

  A training device 1 to which the present invention can be applied will be described with reference to FIG. Here, this figure is a front view of the training device 1, and one (left) plate 11 is shown in cross section. In addition, a two-dot chain line in the figure indicates the right hand H of the user at the time of training, and shows a state where the user touches the outer surface 12b of the plate 12. Note that the left hand is applied to the outer surface 11b of the plate 11 as in the case of the right hand H described above, but this is not shown.

  As shown in the figure, the training device 1 includes a pair of plates 11 and 12 and a holder 15 that rotatably supports the plates 11 and 12 as main components.

  For example, the plate 11 is formed in a shape obtained by cutting a part of a sphere in a plane. That is, it is configured in a three-dimensional shape surrounded by a flat inner surface 11a and a spherical outer surface 11b. Therefore, the plate 11 looks circular when viewed from the left in FIG. At the center C of the plate 11, a cylindrical recess 11c is formed on the inner side, a spot facing portion 11d is formed on the outer side, and a through hole 12g that connects the recess 11c and the spot facing portion 11d is formed.

  The plate 12 is formed in the same manner as the plate 11 described above. That is, it is configured in a three-dimensional shape surrounded by a flat inner surface 12a and a spherical outer surface 12b. Further, in the center C, a recess, a spot facing portion, and a through hole (all not shown) similar to the plate 11 are formed.

  The plates 11 and 12 are arranged such that the inner surfaces 11a and 12a face each other with a gap in a state where the respective centers C are coaxially arranged.

  A thrust bearing (rolling bearing) 15 is interposed between the plates 11 and 12 as a holder. As the thrust bearing 15, a general one, for example, a single-type thrust ball bearing can be used. That is, the thrust bearing 15 has a plurality of balls 15c held by a ball cage (not shown) and a pair of washer disks 15a, 15b having grooves in which these balls 15c roll. The thrust bearing 15 is fixed to the inner side surfaces 11 a and 12 a of the above-described plates 11 and 12 via the fixtures 13 and 14.

  The fixture 13 includes a thin plate-like plate portion 13a and a nut portion 13b that protrudes outward from the center of the plate portion 13a. The attachment 13 has a plate portion 13a fixed to the raceway 15a of the thrust bearing 15 by a fastener (not shown) such as a screw, and the nut portion 13b is disposed in the recess 11c of the plate 11 described above. Has been inserted. The plate 11 is fixed to the fixture 13 by bolts 16. The bolt 16 penetrates the through hole 12g from the outside to the inside, and the tip portion is screwed into the nut portion 13b of the fixture 13 described above. Thereby, the plate 11 is fixed to the fixture 13 so as to sandwich the plate 11 between the fixture 13 and the head of the bolt 16. In addition, since the head of the bolt 16 is configured to be embedded in the spot facing portion 11d of the plate 11, the head protrudes from the outer surface 11b of the plate 11 and is caught on the palm of the user. Absent.

  Since the fixture 14 is the same as the fixture 13 described above, a description thereof will be omitted. Moreover, the attachment method of the plate 12 with respect to this attachment 14 is performed with the volt | bolt (not shown) similarly to the attachment method of the plate 11 with respect to the above-mentioned attachment 13. FIG.

  As described above, the plate 11 and the plate 12 are lightly relative to each other in one direction and the other direction with respect to the other by the thrust bearing 15 as a holder interposed therebetween. Can rotate. Therefore, the user relatively rotates the plates 11 and 12 in opposite directions with the left palm applied to the outer surface 11b of the plate 11 and the right palm applied to the outer surface 12b of the plate 12. Thereby, it can contribute to the training of the whole arm from a wrist to a collarbone. Further, the operability of the entire arm and the whole body (particularly the operability of the upper body) can be improved. Moreover, as a general effect, there exist effects, such as a wrist and a shoulder becoming soft, and the ability to eliminate or prevent a stiff shoulder.

  In addition, according to the present embodiment, the distance between the left palm applied to the outer surface 11b of one plate 11 and the right palm applied to the outer surface 12b of the other plate 12 can be reduced, so both plates By rotating 11 and 12 alternately in one direction and the other direction, the wrist is bent or stretched, and the arm is rotated around the elbow or shoulder to make a large three-dimensional movement. Can do. Therefore, the movement of the entire arm during training can be increased. Unlike the multi-function machine, since no extra parts are incorporated, the structure can be easily operated with a simple structure. Therefore, the plates 11 and 12 are rotated alternately in one direction and the other direction. Can be performed quickly, and this can further enhance the training effect.

As described above, according to the present embodiment, the above-described excellent effects can be obtained with a very simple configuration in which the pair of plates 11 and 12 are rotatably connected via the thrust bearing 15. Can do.
<Embodiment 2>

  The second embodiment will be described with reference to FIG. Here, Fig.2 (a) has shown the front view of the training device 1, and (b) has shown the right view. However, in FIG. 12A, the plate 12 is shown in cross section.

  As described with reference to FIG. 1 of the first embodiment, the plates 11 and 12 are fastened (fixed) to the fixtures 13 and 14 integral with the thrust bearing 15 by bolts 16. That is, it is possible to easily attach and remove the plates 11 and 12 by fastening and releasing the bolts 16.

Therefore, in the present embodiment, plates 12A and 12B that are different from the plate 12 are prepared, and are exchanged as necessary and as required by the user. For example, the plate 12A is thicker than the plate 12, so that the load during training can be increased. The plate 12B has a large number of protrusions 12e on the outer surface. Thereby, the user's palm pot during training can be stimulated. The case where one plate 12 is replaced has been described above as an example, but the other plate 11 can be easily replaced in the same manner. The plates 11 and 12 may have the same shape or different shapes. For example, the plate 11 shown in FIG. 2A may be used, and the other plate may be the plate 12B. A combination of these pair of plates can be arbitrarily selected.
<Embodiment 3>

  The third embodiment will be described with reference to FIGS. These drawings are front views schematically showing the characteristic portions, and both the plates 11 and 12 are shown in cross section. In the present invention, as the holder for rotatably supporting the plates 11 and 12, other than the above-described thrust bearing 15 can be used.

  (A) uses the thrust bearing 15 as a holder which rotatably supports the plates 11 and 12.

  On the other hand, the thing of (b) uses the two radial bearings (rolling bearing) 18 as a holder. As the radial bearing 18, a general bearing, that is, a bearing having an inner race, an outer race, a plurality of balls, and a ball cage can be used. The inner races of the two radial bearings 18 are press-fitted into the left step portion and the right step portion of the large-diameter portion of the shaft having the large-diameter portion at the center, respectively, and the plates 11, 12 is press-fitted.

  Moreover, what is shown to (c) uses the sliding plate pair 19 as a holder. The sliding plate pair 19 is composed of two thin plate-like sliding plates 20 and 21 that rotate relative to each other while sliding. Plates 11 and 12 are fixed to these sliding plates 20 and 21, respectively. The sliding plates 20 and 21 are provided with engaging portions (not shown) that engage with each other. The sliding plates 20 and 21 are relatively rotatable by the engaging portions, and It shall be supported so that it cannot be separated.

  Those shown in (b) and (c) can achieve substantially the same effects as those shown in (a).

Furthermore, what is shown in (d) uses a torque damper 22 as a holder. The plates 11 and 12 are fixed to both ends of the torque damper 22 in the axial direction, respectively. By selecting the torque damper 22 with an appropriate load, the load on the user during training can be made suitable. According to this, substantially the same effects as those of (a) to (c) can be obtained, and also the strength of the arm can be trained. 3 (a) to 3 (b), the fixtures (not shown) corresponding to the fixtures 13 and 14 of the first embodiment are fixed to each holder, and this attachment is performed. You may make it fix the plates 11 and 12 to each holding tool by screwing a volt | bolt in a part of tool. In this case, as in the first embodiment, the plates 11 and 12 can be easily attached and detached.
<Embodiment 4>

  A fourth embodiment will be described with reference to FIGS. 4 (a) and 4 (b). In addition, these figures have shown the cross section of the plates 12 and 12C. Further, the illustration of the plates and holders that are paired with these is omitted.

  The plate 12 shown in (a) has a solid configuration as a whole.

  On the other hand, the plate 12C shown in (b) has an annular hollow portion 12f. By providing the hollow portion 12f in the plate 12C in this way, the weight of the plate 12C itself can be reduced, so that the operation during training can be made smoother as the weight is reduced. Note that water or a liquid having higher viscosity than water may be injected into the hollow portion 12f. In this case, since the movement of the plate 12C and the movement of the liquid inside do not necessarily match, a frictional force acting between the plate 12C and the liquid generates an unexpected force for the user. In addition, the weight of the entire training device and the behavior of the liquid in the hollow portion 12f can be changed by appropriately selecting the viscosity, specific gravity, and viscosity of the liquid to be injected or by adjusting the injection amount. Therefore, a training device suitable for the user can be configured.

Although one plate has been described above, the same applies to the other plate.
<Embodiment 5>

The fifth embodiment will be described with reference to FIGS. In the above-described first to fourth embodiments and FIG. 5A, the side surface shape of the plate 12 is circular. Instead of this, an ellipse may be used as shown in (b), or a complex curve may be used as shown in (c). As described above, the side surface shape of the plate 12 may be set as appropriate according to the convenience of the user. The same applies to the size of each shape. The same applies to the plate 11 (not shown) paired with the plate 12.
<Embodiment 6>

The sixth embodiment will be described with reference to FIGS. These are obtained by changing the front shape of the plate 12. As shown to (a), the inner surface 12a and the outer surface 12b are formed in a parallel plane, and the whole is comprised in disk shape. In the plates 12 of (b) to (d), the inner surface 12a is formed in a flat shape, and the outer surface 12b is formed in a spherical shape. However, the thickness increases in the order of (b), (c), and (d). Thus, the front shape and thickness of the plate 12 are not particularly limited. The same applies to the plate 11 (not shown) paired with the plate 12.
<Embodiment 7>

  A seventh embodiment will be described with reference to FIGS. These show variations in the surface shape of the outer surface 12b of the plate 12.

  In (a), the outer surface 12b is formed smoothly. In (b), annular grooves a, b, and c are provided on the outer surface 12b as slip stoppers. Further, the shape of the groove may be, for example, an oblique V shape as shown in the groove a, an oblique V shape in the reverse direction as shown in the groove b, a V shape as shown in the groove c, and the like. In (c), the outer surface 12b of the plate 12 is roughened to prevent slippage. In (d), a large number of protrusions 12e are provided on the outer surface 12b as a slip stopper. In addition to acting as a slip stopper, the protrusion 12e also acts as a stimulator for the palm as described above. The surface shape of the outer surface 12b of one plate 12 has been described above, but the same applies to the surface shape of the outer surface of the other plate 11 (not shown).

  As described above, the surface shape of the outer surface 12b of the plate 12 can be arbitrarily determined.
