Description

  The present invention relates to an arm exercise apparatus for performing an arm exercise mainly for the purpose of reducing shoulder and arm fatigue.

  In general, when the muscles of the shoulders and arms are fatigued due to intense exercise, etc., muscle fatigue can be reduced by performing multiple patterns of stretching exercises such as torsional exercises that twist the arms and rotational exercises that rotate the forearm part. It is more effective if the stretching exercise is performed by a sports trainer or the like.

  However, in that case, a sports trainer or the like has a drawback of requiring a great amount of labor because it has to keep twisting and turning with the arm of the patient. In addition, sports trainers and the like are attached to one patient and cannot cope with a plurality of patients at the same time, so that there is a problem that inefficient treatment is forced.

  On the other hand, Patent Literature 1 describes an exercise device that can automatically perform rehabilitation of a patient with a joint disorder. In the exercise apparatus described in Patent Document 1, the patient's forearm swings around the elbow by fixing the patient's forearm to an arm that swings within a certain angle range. As a result, the arm is bent and stretched effectively for the rehabilitation of the elbow joint.

  That is, it is considered that by performing an arm stretching exercise using the exercise device described in Patent Document 1, it is possible to reduce muscle fatigue of the arm depending on the case. Conventionally, a sport trainer or the like has been used. It is thought that a small part of the stretch exercise can be automatically performed using the apparatus.

JP-A-8-71113

  However, since the exercise device of Patent Document 1 has only a single function of swinging the arm within a predetermined angle range, the stretch exercise as described above is automated by using this device temporarily. However, the movement pattern is limited to only one type, and the stretch effect is reduced. That is, even if the apparatus of Patent Document 1 is used, it is impossible to effectively reduce muscle fatigue of the shoulders and arms, and it is impossible to perform torsional motion and rotational motion effective for stretching.

  Accordingly, the present invention provides an arm exercise device that can efficiently and effectively perform arm exercises for the purpose of reducing muscle fatigue of shoulders and arms, etc., by solving the above-described problems. The purpose is to provide.

  In order to solve the above-described problems, an arm exercise device according to the present invention includes a holding portion that holds a human hand or wrist, and the holding portion is positioned on a drive shaft axis of a drive mechanism so as to have a predetermined angle. The torsion function that allows the torsion of the arm connected to the holding part in the range, and the forearm that is connected to the holding part, with the holding part located at a position eccentric from the drive shaft axis, are the same with the elbow joint as the center A rotation function that continuously circulates in the direction, and a swing that moves the forearm reciprocally rotated within a predetermined angular range around the elbow joint by positioning the holding part at a position eccentric from the drive shaft axis. It is characterized in that it has at least two of the dynamic functions and can be used by switching between these functions.

  Specifically, it has three functions of the torsion function, the rotation function, and the swing function, and can be used by switching between these functions.

  In addition, the swing operation in the swing function is performed in a plane substantially perpendicular to the rotation operation in the rotation function.

  Furthermore, a rotation arm attached to the drive shaft and rotating about the drive shaft is provided, and within a predetermined range between the drive shaft axis position on the rotation arm and a position eccentric from the axis by a predetermined distance, The holding part is attached to the rotary arm so that the position of the holding part can be changed.

  Furthermore, a universal joint that allows free rotation of the holding portion with respect to the rotating arm in a predetermined angle range is interposed at the connecting portion between the holding portion and the rotating arm.

  The rotating arm is a rotating disk.

  Further, the rotation operation of the rotation function is performed with the drive shaft facing downward, and the torsion operation of the torsion function and the swing operation of the swing function are performed with the drive shaft turned sideways. In these two states, the direction of the drive shaft can be switched.

  Furthermore, the drive shaft and the prime mover that drives the drive shaft are attached to the tip of a support frame that can swing up and down so as to be rotatable in a vertical plane.

  In addition, a cuff for preventing the hand or wrist from coming off by squeezing from the outside in a state where the hand or wrist of the person is wrapped or sandwiched is provided in the holding portion.

  In addition, a pressurizing device for sending air into the cuff is attached to the holding portion so as to be driven integrally with the holding portion.

  By using the arm exercise device according to the present invention, the arm can be exercised more efficiently than when a sport trainer or the like is used. In addition, since the exercise device of the present invention can be used by switching between the torsion function, the rotation function, and the swing function, the muscle fatigue of the shoulders and arms can be achieved by appropriately switching between these functions. It is possible to effectively exercise the arm for the purpose of reducing the above.

  In addition, since the oscillating operation in the oscillating function is performed in a plane substantially perpendicular to the rotational operation in the rotating function, for example, the oscillating operation is performed in the vertical plane, and the horizontal plane Each movement can be performed in a plane in a suitable angular direction, for example, by performing a rotation movement within the arm, and a more effective arm movement can be performed.

  Furthermore, since the holding part that holds the hand or wrist is attached to the rotating arm that rotates about the drive shaft so that the position can be changed within a predetermined range, the above-described switching of each function is performed. The holding unit can be positioned at an appropriate position of the rotary arm, and the position of the holding unit can be adjusted according to the body shape of the user.

  Furthermore, since a universal joint that allows free rotation of the holding portion with respect to the rotating arm within a predetermined angle range is interposed in the connecting portion between the holding portion and the rotating arm, the rotating function and the swinging function are particularly preferable. During the movement of the wrist, it is possible to prevent the wrist from being bent unnaturally, and extra force is not applied to the wrist and the arm, and the stretching exercise can be performed in a sufficiently relaxed state.

  In addition, because the rotating arm consists of a rotating disk, people and objects can be prevented from getting caught in the rotating arm that is in operation, and people near the device can avoid being injured by hitting the rotating arm, The safety of the device can be increased.

  Further, the direction of the drive shaft can be switched so that the drive shaft is in a downward state when performing a rotational operation, and the drive shaft is in a lateral state when performing a twisting operation or a swinging operation. Therefore, when used in a state where the upper arm is laid on a bed or the like with the upper arm substantially perpendicular to the torso, an effective stretching exercise can be performed by each operation.

  Furthermore, the height of the drive shaft and the prime mover can be adjusted by swinging the support frame up and down, and the drive shaft and the prime mover can be adjusted in the vertical direction with respect to the tip of the support frame. By rotating, the direction of the drive shaft can be switched. Therefore, the height and direction in which each of the above operations is performed can be easily switched as necessary.

  Further, since the holding part is provided with a cuff for preventing the hand or wrist from coming off, the user himself / herself grasps the holding part by pressing the user's hand or wrist with the cuff from the outside. Without it, the user's hand or wrist can be held. That is, since each operation is performed in a state where the user is relaxed without putting any force on the hand or arm, the effect of the stretch exercise can be sufficiently exhibited.

  In addition, since the pressurizing device for sending air to the cuff is attached to the holding unit so as to be driven integrally with the holding unit, the pressure feeding hose connecting the pressurizing device and the cuff is held. It is possible to prevent twisting or entanglement during driving of the part.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an arm exercise device (1) according to an embodiment of the present invention. The exercise device (1) includes a drive mechanism (2) having a drive shaft (4) that can be driven to rotate. , A rotating disk (7) as a rotating arm attached to the driving shaft (4) and rotating around the driving shaft (4), and a holding part (8) attached to the rotating disk (7) so that the position can be changed. ).

   The drive shaft (4) of the drive mechanism (2) is connected to a motor (3) with a speed reducer as a prime mover, and is continuously rotated in the same direction by this motor (3) or at a predetermined angle. It is driven to rotate so as to reciprocate within the range. Note that the rotational speed of the motor (3) and the angular range in which the motor (3) is reciprocally rotated can be controlled by a control unit (not shown). The rotation direction when the drive shaft (4) is reciprocally rotated is switched by electrical control using, for example, a relay.

  The drive shaft (4) and the motor (3) are accommodated in, for example, a cylindrical storage case (5). The storage case (5) is connected to a support body (11) erected from a support base (12) through, for example, a pair of support frames (15) and (15). ).

   The support frame (15) (15) is rotatably connected to the upper end portion of the support body (11) on one end side via the first connecting shaft (16), and on the other end side, the housing case. It is rotatably connected to (5) via the second connecting shaft (17).

It has become. Further, when the storage case (5) rotates around the axis of the second connecting shaft (17) with respect to the front ends of the support frames (15) and (15) that can swing up and down, the storage case (5) At the same time, the drive shaft (4) and the motor (3) in the housing case (5) rotate in a vertical plane.

   Thus, the rotation of the drive shaft (4) and the motor (3) is attached to the front ends of the support frames (15) and (15) so as to be rotatable in the vertical plane. The direction of the drive shaft (4) can be switched between the state in which 4) is directed downward and the state in which it is directed horizontally.

   The rotating disk (7) is fixed to the tip of the drive shaft (4) at substantially the center thereof, and when the drive shaft (4) is driven to rotate, it is rotated together with the drive shaft (4). Yes. As shown in FIGS. 5 and 6, the rotary disk (7) has a drive shaft (4) axis position P and its axis P on the surface opposite to the surface on the drive shaft (4) side. A linear guide groove (20) is provided between the center and a position eccentric from the center by a predetermined distance. As shown in FIGS. 2 and 3, the guide groove (20) has, for example, a substantially T-shaped cross section.

   The holding portion (8) is for holding the hand (64) or wrist (65) of the user (59). For example, a cylindrical tube portion (25) and one of the tube portions (25) are provided. And a lid portion (26) for closing the opening. As this holding portion (8), for example, a synthetic resin-made one is used, but is not particularly limited thereto.

  In the holding part (8), a cuff (27) for preventing the user (59) from removing the hand (64) or the wrist (65) is provided. The cuff (27) is attached in the cylinder part (25) so as to be along the inner peripheral surface of the cylinder part (25) in the holding part (8).

  A pressurizing device (29) is connected to the cuff (27) via a pressure feeding hose (28). Then, when the pressurizing device (29) is pressed with the user's (59) hand (64) inserted into the holding portion (8), the cuff (27) is blown by the air fed from the pressurizing device (29). The cuff (27) squeezes the hand (64) or the wrist (65) of the user (59) and presses it from the outside to wrap the hand (64) from the holding part (8). ) Can be prevented from coming off.

  In this way, when the user (59) grasps the device (1) by holding the user (59) hand (64) or wrist (65) by cuff (27) compression In comparison, the user (59) can perform an effective stretching exercise in a relaxed state without putting extra force on the hand (64) or the arm (60). Also, if it is necessary to pull the hand (64) away from the holding part (8) in the event that a failure occurs while using the device (1), the hand (64) should be vigorously pulled from the holding part (8). If it is going to be pulled out, it can be pulled out relatively easily, ensuring safety.

  Further, the pressurizing device (29) is attached to the holding portion (8) at a position close to the holding portion (8) via the cuff (27). That is, the pressurizing device (29) is attached to the holding portion (8) so as to be driven integrally with the holding portion (8), and therefore, the holding portion ( Even if 8) is driven, the pressure feeding hose (28) can be prevented from being tangled or twisted.

  As the pressurizing device (29), a manual pump is used, but the present invention is not particularly limited to this, and for example, an electric pump may be used.

  The holding part (8) is connected to the rotating disk (7) through a first connecting part (35) slidably attached to the guide groove (20) of the rotating disk (7). The first connecting part (35) is slidably fitted in the guide groove (20), and protrudes from the sliding plate (36) toward the holding part (8). And a universal joint (40) connected to the tip of the bolt (38), and a nut (39) screwed to the bolt (38).

  The universal joint (40) is composed of a convex side connecting member (41) and a concave side connecting member (42) that are rotatably engaged with each other. The convex-side connecting member (41) includes a shaft portion (43) connected to the holding portion (8) and a ball-shaped convex portion (44) provided at the tip of the shaft portion (43). . The shaft portion (43) of the convex coupling member (41) is provided so as to protrude from the surface of the lid portion (26) at the approximate center of the surface of the lid portion (26) in the holding portion (8). The concave side connecting member (42) is connected to the tip of the bolt (38) on the rotating disk (7) side, and the convex portion (44) of the convex side connecting member (41) on the holding portion (8) side. ) And a recess (45) that is rotatably engaged.

  Therefore, with respect to the concave coupling member (42) on the rotating disk (7) side, the convex coupling member (41) and the holding portion (8) coupled to the convex coupling member (41) 8) and the concave side connecting member (42) are rotated within a predetermined angle range in which they do not interfere with each other. That is, the universal joint (40) is interposed in the first coupling part (35), so that the holder (8) can freely rotate within a predetermined angle range with respect to the rotating disk (7). It has become. Therefore, while using the device (1), the wrist (65) of the user (59) is prevented from bending unnaturally, and the wrist (65) and arm of the user (59) are prevented. Since extra force can be prevented from entering (60), muscle fatigue can be effectively reduced by performing a stretching exercise using this device (1).

  In addition, since the cover material (46) which covers a part or all of the surface is externally fitted to the concave side coupling material (42), the holding portion (8) is provided with respect to the concave side coupling material (42). Are not in direct contact with each other, and the impact is mitigated by the cover material (46). The cover material (46) is made of, for example, rubber, but is not particularly limited thereto.

  The universal joint (40) is not particularly limited to the above-described configuration. For example, the concave coupling member (42) is provided on the holding portion (8) side, and the convex coupling member (41) is provided. May be provided on the rotating disk (7) side.

  The first connecting portion (35) having the above-described configuration is slidable along the guide groove (20) in a state where the nut (39) is loosened, and the nut (39) is slidable along the sliding plate (36). It is fixed to the rotating disk (7) by being screwed and tightened toward the side. Thus, the 1st connection part (35) can be attached to the arbitrary positions along a guide groove (20) with respect to a rotary disk (7). That is, the holding portion (8) connected to the first connecting portion (35) is between the drive shaft (4) axis position P and the position eccentric from the axis P by a predetermined distance on the rotating disk (7). It is attached to the rotating disk (7) so that the position can be changed within a predetermined range.

  In addition, the device (1) includes a second connecting portion (50) separately from the first connecting portion (35). The second connecting part (50) has a nut (51) with a nut (53) screwed in an intermediate part of the bolt shaft part (52) so that the nut (53) can not advance and retreat, and one end of the bolt (51) can advance and retreat. And a screw hole (54) of the rotating disk (7) into which the other end side of the bolt (51) is detachably screwed.

  The screw hole (54) of the holding part (8) is formed in the thickness part (56) provided on the surface of the lid part (26), and the screw hole (55) of the rotating disk (7) is formed on the rotating disk (7 ) Of the holding portion (8) attached to the drive shaft (4) axis position P of the drive shaft (4) at a position corresponding to the screw hole (54) of the holding portion (8) in that state.

  Then, in the state where the holding portion (8) is attached to the drive shaft (4) axis position P of the rotary disk (7), as shown in FIG. 2, the nut-attached bolt (51) is attached to the holding portion (8). When the screw hole (54) is completely screwed, the nut-attached bolt (51) is removed from the screw hole (55) of the rotary disk (7). That is, in this state, the holding portion (8) is connected to the rotating disk (7) only by the first connecting portion (35) in which the universal joint (40) is interposed, and the drive shaft (4) is rotationally driven. Even so, the driving force is not transmitted to the holding portion (8).

  On the other hand, as shown in FIG. 3, when the bolt (51) with a nut is completely screwed into the screw hole (55) of the rotating disk (7), the bolt (51) is screwed on the rotating disk (7). It will be in the state screwed in both the hole (55) and the screw hole (54) of a holding | maintenance part (8). That is, in this state, the holding part (8) is connected to the rotating disk (7) not only by the first connecting part (35) but also by the second connecting part (50). The driving force on the disk (7) side is transmitted to the holding part (8) side, so that the rotating disk (7) and the holding part (8) are driven integrally.

  However, the configuration of the second connecting portion (50) is that the rotating disc (7) and the holding portion (8) are connected so that the rotating disc (7) and the holding portion (8) are integrally driven. The invention is not particularly limited to this.
