Description

  The present invention relates to a muscle function recovery training device for performing recovery or training of muscle function by pulling an arm.

Various devices for recovering or training muscle functions have been proposed. Some of them are called a rowing machine, and are generated when the arm is pulled by holding the operation unit with fingers. There are those that use resistance to recover and train mainly the functions of rhomboid and latissimus dorsi muscles. In a rowing machine that restores and trains the muscle functions of the rhomboid muscles and latissimus dorsi muscles, it usually extends in the vertical direction and is swung back and forth with one end (upper end or lower end) as a swing fulcrum. When an operation bar is provided and an operation unit provided at the other end of the operation bar is pulled toward the front side, a resistance force is generated (see, for example, Patent Document 1 and Patent Document 2). ).
JP-A-11-164909 Japanese Patent Laid-Open No. 7-308352

  By the way, in order to ideally recover and train the muscle functions of the rhomboid muscles and latissimus dorsi muscles, it is desirable that the movement locus of the operation unit be in a straight line when the operation unit is pulled forward. ing. However, in the conventional apparatus, since the pulling operation using the swing of the operation bar is performed, the movement trajectory of the operation unit inevitably becomes an arc shape, and the movement is inevitably deviated from the ideal movement. Did not get.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a muscle function recovery training apparatus that can ideally recover and train muscle functions of the rhomboid muscles and latissimus dorsi muscles. is there.

In order to achieve the above object, the following solution is adopted in the present invention. That is, as described in claim 1 in the claims,
A frame installed on the floor;
A guide bar held in the frame and extending in a horizontal direction;
A slider slidably held on the guide bar;
An operation unit provided on the slider and gripped by a finger of a user;
A breast pad provided on the frame and in contact with the chest of the user in a state of gripping the operation unit;
Resistance applying means for applying resistance to the slider in the pulling direction of the operation portion;
As provided. In the above-described apparatus, the user holds the operation part with his / her finger in a state where the chest part is in contact with the chest pad part, and the arm part resists the resistance force of the resistance applying unit. Just pull it. At the time of this pulling operation, the chest part is in contact with the breast pad part, so that the upper body does not turn forward or turn over backwards, and the pulling operation with the arm is performed exclusively, The muscle functions of the rhomboid and latissimus dorsi muscles are restored and trained. And since the operation part moves in a straight line in the horizontal direction along the guide bar, the muscle functions of the rhomboid muscles and latissimus dorsi muscles are ideally recovered and trained.

A preferred mode based on the above solution is as described in claim 2 and the following claims. That is,
A pair of left and right operating portions are provided in a positional relationship such that the breast pad portion is positioned between them,
One slider is provided for common use with the pair of left and right operation units.
(Corresponding to claim 2). In this case, only one slider needs to be provided for common use with the pair of left and right operation units, which is preferable in terms of simplification of the structure. In addition, the pulling operation is performed with both the left and right arms, so that the muscle functions of the left and right rhombus and latissimus dorsi muscles can be recovered and trained simultaneously.

A pair of left and right operating portions are provided in a positional relationship such that the breast pad portion is positioned between them,
A pair of left and right sliders are provided so that they can slide independently,
The left operation portion is provided on the left slider, and the right operation portion is provided on the right slider.
(Corresponding to claim 3). In this case, recovery and training of the rhomboid muscles and latissimus dorsi muscles can be performed independently and separately on the left and right sides by pulling only the left and right operation sections. Also, by simultaneously pulling and operating the pair of left and right operation units, the muscle functions of the rhomboid muscles and latissimus dorsi muscles on both the left and right sides can be simultaneously recovered and trained.

  The resistance when only the left slider is pulled and the resistance when only the right slider is pulled are set to be the same resistance, and the pair of left and right sliders are simultaneously When the pulling operation is performed, the size is set to be twice as large as the resistance force when only one of the sliders is pulled (corresponding to claim 4). In this case, the resistance when recovering and training the muscle function on only one of the left and right sides and the resistance when recovering and training the muscle function on both the left and right sides can be made to be ideally distributed sizes.

The slider is integrally provided with an extending portion that extends in parallel with the guide bar toward the breastplate portion,
The operation portion is provided at a distal end portion of the extending portion,
(Corresponding to claim 5). In this case, by interposing the extending portion, it is possible to set the position setting of the operation portion and the position setting of the slider to the optimum positions according to the function in the axial direction of the guide bar.

  The extending portion is positioned above the guide bar (corresponding to claim 6). In this case, a guide bar that tends to be unsightly is positioned below the extended portion, which is preferable in terms of improving appearance. In addition, the extended portion that is positioned above and is easily visible to the user as a whole extends in parallel with the guide bar. Become.

  The operation portion is connected to the slider via a universal joint (corresponding to claim 7). In this case, when pulling the operating portion, it is preferable in terms of not applying an excessive bending force to the user's wrist.

  The slider is configured to be movable only in the axial direction of the guide bar and not to be relatively rotatable around the axis of the guide bar (corresponding to claim 8). In this case, it is preferable to prevent the slider, that is, the operation unit from inadvertently rotating around the axis of the guide bar, and to perform only the pulling operation of the operation unit exclusively linearly.

  The resistance applying means is a weight connected to the slider through a wire such as a wire (corresponding to claim 9). In this case, a weight that is generally used can be used for imparting resistance, which is preferable in terms of cost reduction and the ability to easily change the magnitude of the resistance.

  The breast pad portion is configured such that the position of the guide bar in the axial direction can be adjusted (corresponding to claim 10). In this case, it is preferable to allow the operation unit to be pulled with an appropriate posture in accordance with the difference in the physique of the user, particularly the length of the arm.

  The frame is provided with a seat part whose height position can be adjusted at a position closer to the pulling direction side of the operation part than the breast pad part (corresponding to claim 11). In this case, the user can recover and train in an easy posture while sitting on the seat. Further, since the seat portion is provided on the frame, it is possible to prevent a situation where the seat portion is inadvertently moved in the front-rear direction by a force when pulling the operation portion. Of course, since the height of the seat portion can be adjusted, the optimum height position can be selected in accordance with the user's physique, particularly the height difference.

  According to the present invention, the functions of rhombus and latissimus dorsi muscles can be ideally recovered and trained.

  In FIG. 1, F is a frame, which is configured by combining metal (for example, iron) angle members and combining them by welding or the like. The frame F has a lower frame 1 seated on the floor surface. The lower frame 1 has a central portion 1a that extends in the front-rear direction, a rear portion 1b that extends in the left-right direction at the rear end portion of the central portion 1a, and a front portion 1c that extends in the left-right direction at the front end portion of the central portion 1a. . The lower frame 1 extends from the middle part of the central part 1a to the side, then extends forward along the central part 1a, and finally extends so as to be positioned further forward than the front part 1c. It has the extended part 1d provided.

  In the lower frame 1, a rear frame 2 is extended on the rear portion 1b. The rear frame 2 has a pair of left and right legs 2a extending in the vertical direction and a connecting portion 2b that connects the upper ends of the pair of left and right legs 2a, and has a substantially arch shape as a whole. . A front frame 3 is extended on the front portion 1 c of the lower frame 1. The front frame 3 extends slenderly forward and then extends obliquely rearward from the middle. A holding portion 3a extending short in the left-right direction is formed in the bent portion formed in the vertical middle portion of the front frame 3, and a cylindrical holding portion extending in the front-rear direction is formed in the upper end portion of the front frame 3. 3b is formed.

  A pair of left and right guide bars 4 are installed and held between the front and rear frames 2 and 3. That is, the front end portions of the pair of left and right guide bars 4 are held by the holding portion 3 a in the front frame 3, and the rear end portions of the pair of left and right guide bars 4 are held by the connecting portion 2 b of the rear frame 2. The pair of left and right guide bars 4 are parallel to the floor surface and have a positional relationship such that the central portion 1a of the lower frame 1 is sandwiched from the left and right.

  One slider 5 is slidably held on the pair of left and right guide bars 4. Since the slider 5 is slidably fitted to the pair of left and right guide bars 4, the slider 5 can move in the axial direction of the guide bar 4, but cannot move around the axis of the guide bar 4. Yes. In addition, the slider 5 is configured to be able to move smoothly in the axial direction of the guide bar 4 with a bearing interposed in a fitting portion with the guide bar 4. The slider 5 has a vertically divided structure, for example, and is attached to the guide bar 4 so as to sandwich the guide bar 4 from above and below, and then integrated in the vertical direction by bolts or the like. . Further, when assembling the slider 5 to the guide bar 4, the slider 5 is fitted from the one end side to the guide bar 4 in a state before being attached to the frame F without the slider 5 being divided. In combination, the guide bar 4 after the slider 5 is fitted may be attached to the frame F.

  An extension member 7 is integrated with the upper end portion of the slider 5 via an attachment member 6. The extending member 7 includes a pair of left and right extending portions 7a extending in parallel with the guide bar 4 and a connecting portion 7b that connects the rear ends of the pair of left and right extending portions 7a. Thus, the slider 5 is integrated with the mounting member 6. Such an extending member 7 is configured by bending a cylindrical metal material, for example.

  An operation portion 8 is attached to the front end portions of the pair of left and right extending portions 7a via universal joints 9 (joints that can rotate 360 degrees in the embodiment). The operation unit 8 has a shape that can be gripped by the finger of the user Y. The slider 5 is moved in the horizontal direction along the guide bar 4 by gripping the operation unit 8 and moving in the front-rear direction. The slider 5 is placed on the front surface of the coupling unit 2 b in the rear frame 2. A stopper 10 made of an elastic member (buffer member) that is in contact with the rear end is fixed.

  A weight box B extending in the vertical direction is attached to the extension 1d in the lower frame 1. In the weight box B, as will be described later, a large number of flat weights are stored in a stacked state in the vertical direction. The weight in the weight box B is connected to the slider 5 via a rope 11 such as a wire, rope, or chain. That is, the rope 5 has one end fixed to the lower end of the slider 5 and the other end connected to the weight in the weight box B as described later. The intermediate portion of the rope 5 is guided by a guide pulley 12 held by the frame F. The cord 5 is set so as to extend rearward from the slider 5, and a tensile force in the rearward direction, that is, a resistance force corresponding to the weight of the weight is always applied to the slider 5.

  A breast pad portion 21 is held by a holding portion 3 b provided at the upper end portion of the front frame 3. That is, an elongated extension portion 21a extending horizontally rearward from the rear surface of the breast pad portion 21 made of an elastic member is projected, and the extension portion 21a is slidably fitted into the holding portion 3b. . A plurality of locking holes 21b are formed in the extension portion 21a with a space in the longitudinal direction (guide bar 4 (axis direction thereof)) On the other hand, on the side surface of the holding portion 3d, the locking holes are formed. A stopper member 22 capable of entering into 21b is screwed in. By changing the locking hole 21b into which the stopper member 22 enters, the position in the front-rear direction of the breast pad 21 is changed. The change of the position of the chest pad 21 in the front-rear direction is a stepped type, but it may be a stepless type, and the chest pad 21 as described above is disposed between the pair of left and right extending portions 7a in the left-right direction. It is set to be located.

  A seat 30 that can be adjusted in height is provided at the tip of the extension 1d in the lower frame 1. The seat portion 30 is set so as to be positioned behind the breast pad portion 21 on the front extension line of the central portion 1 a in the lower frame 1. In order to adjust the height of the seat portion 30, a holding cylinder portion 31 extending in the vertical direction is integrated with the extension portion 1 d of the lower frame 1, and extends downward from the lower surface of the seat portion 30 in the holding cylinder portion 31. The extension 30a is slidably fitted. By adjusting the fitting depth of the extended portion 30a into the holding cylinder portion 31 in accordance with the user's physique (stepless adjustment), the lock member 32 screwed to the side surface of the holding cylinder portion 31 is tightened. The height of the seat 30 is fixed. As the height adjustment method, for example, an appropriate structure such as one using a gas spring can be adopted, and the height adjustment can be performed stepwise.

  Next, an example of the connection relationship between the slider 5 and the weight will be described with reference to FIG. First, a moving pulley (moving pulley) 41 is disposed in the weight box B above the stacked weights 40, and a guide pulley 42 is held at a position higher than the moving pulley 41. The strip 11 extending from the slider 5 passes through the guide pulley 42 in the weight box B, then extends downward, passes through the moving pulley 41, then extends upward, and finally is above the moving pulley 41. It is fixed to the fixing part 42. That is, one end portion of the rope 11 is fixed to the slider 5 and the other end portion is fixed to the fixing portion 42. The movable pulley 41 can be moved only in the vertical direction by a guide (not shown).

  A connecting member 44 that extends downward extends from the moving pulley 41. A plurality of locking holes 45 are formed in the connecting member 44 at intervals in the vertical direction. A through hole 40a through which the connecting member 44 is inserted is formed at the center of each weight 40, and an opening 40b corresponding to the locking hole 45 is formed. By inserting the connecting pin 46 into the locking hole 45 through the opening 40 b, only the weight 40 positioned above the connecting pin 46 is interlocked with the moving pulley 41. By changing the connecting position by the connecting pin 46, the number of weights 40 acting as a load on the moving pulley 41 is changed. Although not shown in FIG. 4, a larger number of weights 40 exist below the displayed weight 40.

  A half of the load applied to the moving pulley 41 via the connecting member 44 acts as a resistance force that pulls the slider 5 backward. More specifically, when the weight of one weight 40 is 5 kg, for example, in the case shown in FIG. 4, a total of four weights 40 act on the connecting member 44, so that the moving pulley 41 A total load of 20 kg is applied to. And the resistance force which pulls the slider 5 backward is 10 kg which is half the weight of 20 kg. Note that the rope 11 is drawn out from the lower end of the weight box B, and the height of the slider 5 and the like is drawn at a position higher than the actual height.

  5 and 6 show another embodiment of the present invention. The same components as those in the above-described embodiment are given the same reference numerals, and redundant description thereof is omitted. In this embodiment, a pair of left and right sliders 5 to which the operation unit 8 is attached are provided independently. Accordingly, two guide bars 4 are provided for each slider 5. The rope 11 has one end connected to one slider 4 and the other end connected to the other slider 5. And the rope 11 passes through the moving pulley 41 in the weight box B similarly to the case of the said embodiment.

  In the present embodiment, the load, that is, the resistance force when the other slider 5 (the operation portion 8) is pulled in the state where the one slider 5 is positioned at the rearmost end in contact with the stopper 10, is the moving pulley 41. The weight is half the weight of the weight 40 acting on. Further, the total right and left resistance when both sliders 5 (the operation unit 8) are pulled simultaneously is the same as the weight of the weight 40 acting on the movable pulley 41. Thus, the magnitude of the resistance force when pulling both sliders 5 (operation unit 8) simultaneously is double the resistance force when pulling only one slider 5 (operation unit 8). The The rope 11 is drawn out from the lower end of the weight box B to the outside. In FIG. 6, the height of the slider 5 or the like is depicted at a position higher than the actual height, and the height positions of the pair of left and right sliders 5 or the like are depicted differently, but the actual height is the same. It is.

  In this apparatus, as shown in FIG. 3, the user Y sits on the seat portion 30 and holds the chest portion 21 in contact with the chest portion 21 and pulls the operation portion 8. That's fine. Since the slider 5 can move only in the horizontal direction, muscles near the shoulder, particularly the rhomboid muscles and latissimus vertebrae muscles are ideally recovered and trained. In addition, according to the user's Y physique, the height of the seat part 30 is adjusted and the front-back direction position of the breast pad part 21 is adjusted.

  Although the embodiment has been described above, the present invention is not limited to the embodiment, and can be appropriately changed within the scope described in the scope of claims. For example, the invention includes the following cases. . The seat portion 30 may not be provided, and the seat portion 30 may not be provided integrally with the frame F, and the function of the seat portion 30 may be obtained using an existing seat chair. it can. Further, when performing recovery and training in a standing posture, the seat portion 30 is not required at all. In order to prevent the slider 5 from relatively rotating around the axis of the guide bar 4, an appropriate method can be adopted. For example, the cross-sectional shape of the fitting portion between the guide bar 4 and the slider 5 is different from a circular shape. The rotation of the apparatus may be restricted by adopting the shape. In this case, the number of guide bars 4 provided for one slider 5 can be limited to one. The slider 5 and the guide bar 4 can be fitted into each other by, for example, engaging an engagement protrusion formed on the slider 5 in a long groove formed in the guide bar 4 extending in the axial direction. In this case, relative rotation of the slider 5 with respect to the guide bar 4 can be regulated together. It is also possible to provide the operation unit 8 directly on the slider 5 without using the extending portion 7a.

  The position adjustment of the guide bar 4 in the axial direction between the chest rest part 21 and the operation part 8 may be performed on the operation part 8 side instead of on the chest support part 21 side (for example, the length of the extending part 7a is set). Can be changed). In order to apply the resistance force to the slider 5, not only when the weight 40 is used, but an appropriate one such as an air spring may be adopted. The resistance force applied to the slider 5 is not limited to a constant value at all times, and can be appropriately set such that the resistance force gradually increases as the pulling operation amount with respect to the slider 5 increases. The weight box B can be provided separately from the frame F without being integrated with the frame F. The weight box B portion is shown in principle in FIGS. 4 and 6, but an existing weight box can be used as it is. Of course, the object of the present invention is not limited to what is explicitly stated, but also implicitly includes providing what is substantially preferred or expressed as an advantage.
