Embodiments for Carrying Out the Invention

[0016] [Embodiment] Hereinafter, a training device 1 according to an embodiment of the present invention will be described. FIG. 1 is a diagram showing the appearance of the training device 1. The training device 1 includes a weight 11 (an example of a load generation unit) that generates a load by its own weight, a rail 12, a sliding unit 13 slidably attached to the rail 12 on the rail 12, a load transmission member 14 having one end connected to the weight 11 and the other end connected to the sliding unit 13, and a seat 15 that supports the buttocks and back of a user who uses the training device 1.

[0017] In the present application, the "rail" means a member that guides an object (the sliding unit in the present application) to move on a predetermined movement path that draws a straight line or a curve.

[0018] The user sits on the seat 15, bends the right foot (or left foot), presses the sole of the right foot (or left foot) against the rotating part 1301 of the sliding unit 13, and extends the right foot (or left foot) so as to push up the sliding unit 13 biased in the lower right direction of FIG. 1 by the weight 11 via the load transmission member 14 in the upper left direction of FIG. 1. At this time, a load is applied to the right foot (or left foot).

[0019] The user can strengthen the muscle strength of the right foot (or left foot) by repeating the flexion and extension of the right foot (or left foot).

[0020] As the user flexes and extends the right foot (or left foot), the right foot (or left foot) rotates around an axis along the direction of flexion and extension of the right foot (or left foot). In order not to limit the rotation of the right foot (or left foot), the rotating part 1301 is rotatably attached to the housing of the sliding unit 13.

[0021] The rotating part 1301 is configured such that, as it rotates clockwise or counterclockwise from its reference position, a load of the weight 11 is applied in the rotational direction to return to the reference position via the load transmission member 14 and a load transmission mechanism (described later) provided in the sliding unit 13.

[0022] Therefore, a load is also applied to the rotation of the right foot (or left foot) accompanying the flexion and extension of the right foot (or left foot) by the user. This load improves the effect of training for the right foot (or left foot).

[0023] The load transmission mechanism provided in the sliding unit 13 will be described below.

[0024] (First Embodiment) FIG. 2 is a diagram showing the configuration of the first embodiment of the sliding unit 13. Hereinafter, the sliding unit 13 of the first embodiment is referred to as the sliding unit 13(1).

[0025] The sliding unit 13(1) is detachably attached to the rail 12 so as to be slidable on the rail 12, and includes a housing 1300 that slides on the rail 12 as the user trains, a rotating part 1301 that is rotatably attached to the housing 1300 and receives force from the user's body during training, a bevel gear 1302 (an example of a first bevel gear) attached to the rotation axis of the rotating part 1301, a bevel gear 1303 (an example of a second bevel gear) that meshes with the bevel gear 1302, a crank 1304 attached to the rotation axis of the bevel gear 1303 and that rotates as the bevel gear 1303 rotates, and a connecting member 1305 that connects the crank 1304 and the load transmission member 14.

[0026] Note that the crank 1304 of the sliding unit (1) is provided with a slit that penetrates in the Y direction so as to draw an arc when viewed in the Y direction, and the crank 1304 and the connecting member 1305 are connected by a pin that penetrates the slit. Therefore, as the crank 1304 rotates around the axis in the Y direction, the pin moves freely within the slit, and the crank 1304 moves the load transmission member 14 in the Z direction via the connecting member 1305.

[0027] Figure 2 shows the state where the rotating part 1301 is in the reference position. In this state, no load is applied to the rotating part 1301.

[0028] Figure 3 is a diagram showing the state where the rotating part 1301 has rotated clockwise as viewed by the user. In this state, since the crank 1304 pulls the load transmission member 14 in a direction against the biasing force via the connecting member 1305, a load is applied to the rotating part 1301 in the counterclockwise direction, that is, in the rotational direction to return the rotating part 1301 to the reference position.

[0029] Figure 4 is a diagram showing the state where the rotating part 1301 has rotated counterclockwise as viewed by the user. Also in this state, since the crank 1304 pulls the load transmission member 14 in a direction against the biasing force via the connecting member 1305, a load is applied to the rotating part 1301 in the clockwise direction, that is, in the rotational direction to return the rotating part 1301 to the reference position.

[0030] (Second Embodiment) Figure 5 is a diagram showing the configuration of the second embodiment of the sliding unit 13. Hereinafter, the sliding unit 13 of the second embodiment is referred to as the sliding unit 13(2).

[0031] In Figure 5, with respect to the components provided in the sliding unit 13(2) that are common or corresponding to the components provided in the sliding unit 13(1), the same reference numerals as those used in the sliding unit 13(1) are used.

[0032] The sliding unit 13(2) has different shapes of the crank 1304 and the connecting member 1305 compared to the sliding unit 13(1).

[0033] A member (hereinafter referred to as "slit member") provided with a slit penetrating in the Y direction so as to draw an arc when viewed in the Y direction is connected to the connecting member 1035 of the sliding unit 13(2). The crank 1304 is connected to the slit member such that a pin extending in the Y direction of the crank 1304 penetrates through the slit of the slit member. Therefore, as the crank 1304 rotates about the axis in the Y direction, the pin moves freely within the slit, and the crank 1304 moves the load transmission member 14 in the Z direction via the slit member and the connecting member 1305.

[0034] FIG. 6 is a diagram showing a state in which the rotating portion 1301 rotates clockwise as viewed from the user. FIG. 7 is a diagram showing a state in which the rotating portion 1301 rotates counterclockwise as viewed from the user.

[0035] (Third Embodiment) FIG. 8 is a diagram showing the configuration of the third embodiment of the sliding unit 13. Hereinafter, the sliding unit 13 of the third embodiment is referred to as the sliding unit 13(3).

[0036] In FIG. 8, with respect to the components provided in the sliding unit 13(3) that are common or corresponding to the components provided in the sliding unit 13(1), the same reference numerals as those used in the sliding unit 13(1) are used.

[0037] Similar to the sliding unit 13(2), the sliding unit 13(3) also has different shapes of the crank 1304 and the connecting member 1305 compared to the sliding unit 13(1).

[0038] In the sliding unit 13(3), the crank 1304 and the connecting member 1305 are connected via a member (hereinafter referred to as "intermediate member"). The crank 1304 and the intermediate member are rotatably connected about the axis in the Y direction. Also, the connecting member 1305 and the intermediate member are rotatably connected about the axis in the Y direction.

That is, the rotation axes of the bevel gear 1303, the crank 1304, and the pinion 1307 are inclined with respect to both the X direction and the Y direction when viewed in the Z direction. In this way, by inclining the rotation axes of the crank 1304 etc. in the Z direction with respect to the Y direction and the X direction, the longitudinal direction of the rotating part 1301 in the Z direction at the reference position becomes the Y direction, and when the rotating part 1301 rotates clockwise or counterclockwise from the reference position, a load corresponding to the rotation angle from the reference position is applied to the rotating part 1301.

[0045] FIG. 12 is a diagram showing a state in which the rotating portion 1301 rotates clockwise as viewed from the user. Further, FIG. 13 is a diagram showing a state in which the rotating portion 1301 rotates counterclockwise as viewed from the user.

[0049] A roller chain may be used instead of the drive belt 1310.

[0050] The crank 1304 of the sliding unit 13(1) rotates around the axis in the Y direction, while the crank 1304 of the sliding unit 13(5) rotates around the axis in the X direction.

[0051] The sliding unit 13(5) does not include the connecting member 1305, and the load transmission member 14 is directly connected to the crank 1304. Note that, not limited to this embodiment, the power transmission mechanism of the sliding unit 13 according to the present invention may be connected via the load transmission member 14 and the connecting member 1305, or may be connected without passing through the connecting member 1305.

[0052] In the sliding unit (5), a portion formed in a ring shape at the tip of the load transmission member 14 is hooked onto a pin protruding in the X direction from a crank 1304 that rotates about an axis in the X direction.

[0097] [Modification Example] The above-described first embodiment is one embodiment of the present invention, and can be variously modified within the scope of the technical idea of the present invention. Examples of such modifications are shown below. Note that two or more of the following modification examples may be appropriately combined.

[0098] (1) The type of the training device according to the present invention is not limited to that shown in FIG. 1. That is, the training device according to the present invention is any type of training device as long as it includes a load generation unit that generates a load, a rail, a sliding unit slidably attached to the rail, and a load transmission member having one end connected to the load generation unit and the other end connected to the sliding unit, and transmitting the load generated by the load generation unit to the sliding unit.

[0099] These training devices include, for example, a training device that applies a load to the left or right arm when the user flexes and extends the left or right arm, a training device that applies a load to each of the left and right arms when the user flexes and extends both the left and right arms simultaneously, a training device that applies a load to the left or right leg when the user flexes and extends the left or right leg, a training device that applies a load to each of the left and right legs when the user flexes and extends both the left and right legs simultaneously, and the like.

[0100] (2) The shape, size, arrangement, etc. of the members constituting the training device 1 or the sliding unit 13 shown in the figure are examples and may be variously changed.

[0101] (3) A speed changer may be provided to change the amount of movement of the load transmission member 14 when the rotating part 1301 rotates by a predetermined angle clockwise and counterclockwise from the reference position. In that case, the type of speed changer provided in the sliding unit 13 may be any type. For example, the speed changer provided in the sliding unit 13 may be a stepped speed changer or a continuously variable speed changer. Also, the speed changer provided in the sliding unit 13 may be mechanical, fluidic, electric, or the like.

[0102] FIG. 44 is a diagram showing an example of the speed changer according to this modification. The speed changer 131 shown in FIG. 44 is adopted, for example, in place of the pinions 1309 provided in the sliding units 13(5), 13(6), and 13(7) shown in FIGS. 14, 17, and 20.

[0103] The speed changer 131 includes three pinions with different numbers of teeth, that is, pinions 1309(1), 1309(2), and 1309(3), and a derailleur 1324 that changes the pinion with which the drive belt 1310 meshes among these three pinions. Note that the number of pinions provided in the speed changer 131 is not limited to three.

[0104] The delay lever 1324 includes a main body 13241 that expands and contracts in the left - right direction of the figure according to a user's operation, and a guide plate 13242 that moves the drive belt 1310 in the left - right direction of FIG. 44 as the main body 13241 expands and contracts.

[0105] FIG. 44(A) shows a state where the drive belt 1310 is engaged with the pinion 1309(1), and FIG. 44(B) shows a state where the drive belt 1310 is engaged with the pinion 1309(3).

[0106] When the rotating part 1301 rotates clockwise or counterclockwise from the reference position by a predetermined angle, and the drive belt 1310 moves by a predetermined distance accordingly, the rotation speeds of the pinions 1309(1) - 1309(3) driven by the drive belt 1310 are inversely proportional to the number of teeth of those pinions. That is, when the drive belt 1310 moves by a predetermined distance, the rotation speed of the pinion 1309(1) with the fewest teeth is the highest, and the rotation speed of the pinion 1309(3) with the most teeth is the lowest. Therefore, when the rotating part 1301 is rotated by a predetermined angle from the reference position, the load applied to the rotating part 1301 is the maximum when the drive belt 1310 is engaged with the pinion 1309(1) (FIG. 44(A)), and the minimum when the drive belt 1310 is engaged with the pinion 1309(3) (FIG. 44(B)).
