[0013] Hereinafter, embodiments of a reformer exercise device according to the present invention will be described with reference to FIGS. 1 to 5.

[0014] FIG. 1 is a perspective view showing an embodiment of a reformer exercise apparatus according to the present invention, FIG. 2 is a side view of a carriage, and FIG. 3 is a cross-sectional view taken along line A-A in FIG. 2. Further, FIG. 4 is an enlarged view of a portion surrounded by an imaginary line B in FIG. 3, and FIG. 5 is a view showing a state in which a position adjusting fitting is moved in the direction indicated by arrow C. Note that the arrows in the figures indicate the vertical direction (the direction of the arrows is an example).

[0015] In FIG. 1, reference numeral 1 indicates an embodiment of a reformer exercise apparatus according to the present invention. This reformer exercise apparatus 1 includes a frame 2 having a rectangular (rectangular) shape in plan view, a carriage 3 disposed on the frame 2 and movable between one end 5 and the other end 6 in the longitudinal direction of the frame 2, and a plurality of elastic members, i.e., springs (not shown) connecting the other end 6 of the frame 2 and the carriage 3. Hereinafter, each component of the reformer exercise apparatus 1 will be described.

[0016] First, the frame 2 will be described. The frame 2 shown in FIG. 1 includes rail members 8 provided inside each of the long side portions 7 of the frame 2. The pair of rail members 8 extend from the vicinity of one end 5 to the vicinity of the other end 6 of the frame 2 and are arranged to face each other. In this embodiment, the one end 5 side of the frame 2 is mainly the side where the user's head is located. A pair of pulley assemblies 9 are arranged on the one end 5 side of the frame 2. The pulley assembly 9 includes a rod-shaped arm member 10 and a pulley 11 provided at the tip of the arm member 10. A rope 44 connected to one end 22 of the carriage 3 described later is attached to the pulley 11. The arm member 10 is provided so that its height can be adjusted, although a detailed description thereof is omitted.

[0017] On the other end 6 side of the frame 2, in this embodiment, it is mainly the side where the user's leg side is located. A foot bar 12 is arranged on the other end 6 side of the frame 2. The foot bar 12 is a member for the user to move the carriage 3 along the rail member 8 by pressing with the foot. The foot bar 12 is attached to the long side portion 7 of the frame 2 so that the inclination angle with respect to the frame 2 can be adjusted. By adjusting the front-rear position and height of the foot bar 12, it becomes possible to perform exercises according to the user's physique.

[0018] Next, the carriage 3 will be described. The carriage 3 shown in FIGS. 1 and 2 includes a carriage body 13, a carriage frame 14, a support roller 15, a roller position adjustment mechanism 16, and a guide roller 17. The other end 23 side of the carriage 3 is connected to the other end 6 of the frame 2 via a plurality of springs (not shown). It is assumed that the user can arbitrarily change the number of springs.

[0019] The carriage body 13 shown in FIG. 1 is formed in a rectangle, and a rectangular cushion pad 18 is arranged on the upper surface. On one end 22 side of the carriage body 13, a pair of shoulder rests 19, a headrest 20, and a pair of rope brackets 21 are provided. The shoulder rest 19 is provided as a portion where the user's shoulder abuts when the user lies on their back on the carriage 3 during exercise. The headrest 20 is fixed between the shoulder rests 19 by a hinge (not shown) at the base end of the headrest 20. The rope bracket 21 is provided to be able to fix one end of the rope 44. One end of the rope 44 is fixed to the rope bracket 21, passes through the pulley 11 of the pulley assembly 9, and a holder 45 is attached to the other end. The user performs exercises with the holder 45 attached to, for example, the user's foot or the shoulder rest 19 of the carriage body 13.

[0020] The carriage frames 14 shown in FIGS. 2 and 3 are provided in a pair on the lower surface of the carriage body 13. The pair of carriage frames 14 extend from one end 22 side in the longitudinal direction of the carriage body 13 to the other end 23 side and are arranged parallel to the rail member 8.

[0021] The support rollers 15 shown in FIGS. 2 and 3 are arranged in a pair on each of one end 22 side and the other end 23 side of the carriage body 13. The support rollers 15 are pivotally supported on the outer surface 37 of the carriage frame 14 via the rotating shafts 26. As shown in FIGS. 2 and 4, the support rollers 15 are pivotally supported so as to contact the horizontal surface 24 of the rail member 8 and be able to roll on the horizontal surface 24. The support rollers 15 are formed of a material having rigidity and a low coefficient of friction.

[0022] The roller position adjusting mechanisms 16 shown in FIGS. 2 to 5 are arranged in a pair on each of one end 22 side and the other end 23 side of the carriage body 13. The roller position adjusting mechanisms 16 are connected to the carriage frame 14 so as to be able to be separated from and approach the vertical surface 25 of the rail member 8. The guide rollers 17 are pivotally supported on the roller position adjusting mechanisms 16 via the rotating shafts 27. As shown in FIG. 4, the guide rollers 17 are pivotally supported so as to contact the vertical surface 25 of the rail member 8 and be able to roll on the vertical surface 25. The guide rollers 17 are formed of an elastic material.

[0023] The roller position adjusting mechanism 16 shown in FIGS. 4 and 5 includes a position adjusting fitting 28, a connecting member 29, and a biasing member 30. The position adjusting fitting 28 is a member composed of a first fitting 31 and a second fitting 32. The first fitting 31 is formed in an L shape and has a vertical portion 33 and a horizontal portion 34 continuous with the vertical portion 33. The second fitting 32 is also formed in an L shape and has a vertical portion 35 and a horizontal portion 36 continuous with the vertical portion 35. As shown in FIG. 4, the vertical portion 35 of the second fitting 32 is formed to be longer in the vertical direction than the vertical portion 33 of the first fitting 31.

[0024] The position adjusting fitting 28 shown in FIGS. 4 and 5 has one end side (the vertical portions 33, 35 side) connected to the carriage frame 14 and guide rollers 17 arranged on the other end side (the horizontal portions 34, 36 side). The position adjusting fitting 28 is connected to the carriage frame 14 so that the position adjusting fitting 28 can be separated from and approximated to the carriage frame 14 and the vertical surface 25 of the rail member 8.

[0025] The rotating shafts 27 of the guide rollers 17 shown in FIGS. 4 and 5 are provided across the horizontal portions 34, 36. One end of the rotating shaft 27 is inserted into a long hole (not shown) formed through the lower surface 39 of the carriage frame 14, and the other end is fixed with a nut on the horizontal portion 36 side. Although not particularly shown, the long hole is formed to extend in the width direction of the carriage 3.

[0026] The connecting member 29 shown in FIGS. 4 and 5 is a member that connects the position adjusting fitting 28 and the carriage frame 14 so that the position adjusting fitting 28 can be separated from and approximated to the carriage frame 14 and the vertical surface 25 of the rail member 8. The connecting member 29 consists of a bolt 40 having a shaft portion 42 and a head portion 43, and a nut 41 screwed onto the tip of the shaft portion 42. The shaft portion 42 is formed to be insertable into holes (not shown) formed through the vertical portions 33, 35 and the inner side surface 38 of the carriage frame 14 respectively.

[0027] The biasing member 30 shown in FIGS. 4 and 5 is a "spring" having elasticity to return in the longitudinal direction when compressed, and is formed to be insertable into the shaft portion 42 of the bolt 40 constituting the connecting member 29. The biasing member 30 is arranged so as to be able to bias the position adjusting fitting 28 closer to the carriage frame 14 and the vertical surface 25 of the rail member 8 via the connecting member 29. More specifically, the biasing member 30 is inserted into the shaft portion 42 of the bolt 40 and arranged in a compressed state between the head portion 43 of the bolt 40 and the carriage frame 14.

[0028] Here, the operation of the roller position adjusting mechanism 16 will be described. As shown in FIG. 4, by disposing the biasing member 30 in a compressed state between the head 43 of the bolt 40 and the carriage frame 14, the biasing member 30 tends to return in the longitudinal direction. As the biasing member 30 attempts to return, a force acts on the position adjusting fitting 28 to approach the carriage frame 14 and the vertical surface 25 side of the rail member 8.

[0029] As shown in FIG. 5, when the position adjusting fitting 28 is moved in a direction away from the carriage frame 14 and the vertical surface 25 of the rail member 8 (see the arrow C shown in FIG. 5), the guide roller 17 moves away from the vertical surface 25, but the biasing member 30 compressed more than in the state of FIG. 4 tends to return in the longitudinal direction (see the arrow D shown in FIG. 5). For this reason, the position adjusting fitting 28 is biased toward the carriage frame 14 and the vertical surface 25 side via the connecting member 29.

[0030] As described above, according to the present embodiment, the position adjusting fitting 28 is biased in a direction approaching the carriage frame 14 and the vertical surface 25 by the biasing member 30. For this reason, even when the position adjusting fitting 28 is separated from the carriage frame 14 and the vertical surface 25, the guide roller 17 pivotally supported by the position adjusting fitting 28 abuts against the vertical surface 25 due to the above biasing.

[0031] Further, according to the present embodiment, since the guide roller 17 is formed of an elastic material, the guide roller 17 easily adheres to the vertical surface 25. Since the guide roller 17 rolls on the vertical surface 25 while adhering to the vertical surface 25, good guiding by the guide roller 17 during the movement of the carriage 3 can be performed.

[0032] Next, the effects of this embodiment will be described. As described above with reference to FIGS. 1 to 5, according to the present embodiment, even if the movement of the carriage 3 between one end 5 and the other end 6 of the frame 2 continues, the displacement of the guide roller 17 hardly occurs, and the guide roller 17 always rolls on the vertical surface 25 of the rail member 8, so that the guide by the guide roller 17 during the movement of the carriage 3 can be performed better than in the prior art.

[0033] In addition, it goes without saying that the present invention can be variously modified without departing from the gist of the present invention.
