When the second receiving surface (56) and the second contact surface (65) are omitted or the handle post (60) is stored together with the second receiving surface (56) and the second contact surface (65). Further, the footboards (33) (34) and the handle post (60) may be in direct contact with each other. In this case, since the cushions (35) and (35) of the footboards (33) and (34) receive the handle post (60), the handle post (60) is not damaged.

  A handle (70) is attached to the upper end of the handle post (60) as shown in FIG. The handle (70) is rotatably supported by the handle post (60) by a handle shaft portion (71) penetrating the handle post (60) from side to side. As shown in FIGS. 1 to 4, the handle (70) has a handle shaft portion (71) protruding from the handle post (60) to the left and right, and an upwardly bent arm portion (72) (72). And the distal ends of the arm portions (72) and (72) are bent inward to form the grip portion (73). The grip portions (73) and (73) face each other with a predetermined interval. The grip part (73) is a part where the user holds or places the elbow. The reason why the gap is provided between the grip portions 73 and 73 is to make it easier for the user to visually recognize the operation display portion 90 during use, as shown in FIG.

It is desirable that the handle (70) has a structure that can be fixed so that it does not wobble or rotate during use. 17 and 18 show an example.
As shown in FIG. 18, a U-shaped handle support fitting (76) having an open bottom is fixed to the upper end of the support post frame (60a) of the handle post (60). The support fitting (76) has an opening (76a) for inserting the handle shaft portion (71) from above from the upper surface to the left and right side surfaces (76b). The shape of the lower ends on both the left and right sides of the opening (76a) is a shape that matches the shape of the shaft portion (71) so as to receive the handle shaft portion (71) from below, thereby forming the bearing portion (76c). The handle spacer (74) (74) is turned around the handle shaft (71), and the shaft (71) is inserted into the opening (76a) of the handle support bracket (76) from above, so that the handle shaft (71) Is supported by the bearing portion (76c) through the handle spacers (74) (74).

  Further, from the direction of arrow A in FIG. 17, the U-shaped handle holding metal fitting (77) whose bottom is opened is inserted into the U-shaped handle support metal fitting (76). The left and right side surfaces (77a) of the handle pressing metal fitting (77) are shaped to match the shape of the shaft portion (71) so that the handle shaft portion (71) is pressed from the direction of arrow A, and the holding portion ( 77b) is formed. The handle shaft part (71) is clamped between the bearing part (76c) and the holding part (77b) via the handle spacer (74), and finally the handle holding part (77) is fixed to the handle support part (76). .

A fixed plate (71a) is fixed to the handle shaft portion (71) below. A nut mounting plate (75b) to which a nut (75a) is fixed is fixed to the support post frame (60a) of the handle post (60). With the fixing plate (71a) in contact with the nut mounting plate (75), the handle fixing screw (75) is tightened to the nut (75a) from the rear of the handle post (60), so that the handle (70) The grip portion (73) can be fixed without shaking at a predetermined position.
The handle (70) can be rotated by loosening the handle fixing screw (75).

  In the retracted state, as shown in FIGS. 5 to 9, the handle (70) is rotated to a position where the grip portions (73) (73) approach the handle post (60), so that the handle (70) is obstructed. The handle post (60) can be stored without becoming. Here, before the grip portion (73) hits the handle post (60), the fixing plate (71a) hits the handle presser fitting (77) and its rotation is restricted.

  The operation display section (90) is formed at the upper end of the handle post (60). The operation display section (90) displays various buttons (not shown) operated by the user, the state of the passive exerciser (10), exercise time, calories consumed, METs (metabolic equivalents), etc. (92) with. In addition, METs are the exercise | movement intensity | strength which converts and shows how many times the user's metabolic rate in passive exercise is equivalent to the metabolic rate at rest.

  In the passive exerciser (10) having the above-described configuration, the handle post (60) or the handle (70) is grasped from the retracted state shown in FIGS. 5 to 9 so as to be in the use state shown in FIGS. Raise the handle post (60). When the handle post (60) stands up to a substantially vertical position, the first contact surface (63) of the handle post (60) comes into contact with the first receiving surface (54) of the handle base (51) and is positioned. In this state, the handle post (60) is fixed to the handle base (51) by screwing the post fixing screw (64) into the nut (55). The first contact surface (63) of the handle post (60) presses the button (41) provided on the handle base (51) when the handle post (60) is raised, and the switch (40) is activated. In this state, the power can be turned on.

  Next, the handle (70) is rotated and aligned so that the grip part (73) is at a predetermined height.In this state, the handle fixing screw (75) is tightened to bring the handle (70) into the handle. Fixed to post (60).

When the user grabs the handle (70), puts the left and right feet on the footboards (33) and (34), and sets the desired speed, time, and other programs by operating the operation display unit (90), The motor (82) rotates at the set speed, the rotating plate (31) of the unit section (30) rotates left and right by a predetermined angle, and the footboards (33) (34) alternately tilt up and down.

By the above, the user can receive a stepping exercise and a waist twisting exercise.

  When storing after completion of the exercise (including the initial shipping packaging), loosen the handle fixing screw (75) and rotate the handle (70) to the position shown in FIGS. 70) is stored. Next, the post fixing screw (64) is loosened, and the handle post (60) is tilted backward as shown in FIGS. When the handle post (60) is tilted backward, the first contact surface (63) of the handle post (60) is separated from the button (41) provided on the handle base (51). By force, the button (41) returns the switch (40) and controls the passive exerciser (10) so that it is not turned on. Therefore, except for the case where the handle post (60) is correctly fixed, the passive exercising device (10) is not turned on, so that an erroneous operation can be prevented.

  When the handle post (60) is tilted backward to the position shown in FIGS. 5 to 9, the second contact surface (65) of the handle post (60) is brought into contact with the second receiving surface (56) of the handle base (51). The storage is completed. When storing, the handle post (60) does not contact the handle base (51) but the handle post (60) hits the treads (33) (34), so that the storage can be completed. In this case, in order to increase the stability when the handle post (60) is retracted, the rotating plate (31) of the unit part (30) has the tread plates (33) (34) left and right relative to the handle post (60). It is desirable to perform control so that the treads (33) and (34) are stopped at the same height in a symmetrical position. The handle post (60) is stably stored as the handle post (60) contacts the treads (33) and (34) simultaneously. Further, since the handle post (60) hits the cushions (35) and (35) provided on the footboards (33) and (34), the handle post (60) is not damaged.

  As described above and shown in FIGS. 5 to 9, the passive exerciser (10) can be made compact by folding the handle post (60), so that space saving during storage can be achieved.

  There is a gap between the opening (37) of the rotating plate (31) and the stepping plate (33) (34) .If foreign matter enters the gap, the stepping plate (33) is prevented from tilting. As shown in FIG. 19, in the gap between the opening (37) and the tread plate (33) of the rotating plate (31), protection along the periphery of the opening (37) is caused. It is desirable to provide a wall (38). The protective wall (38) can be formed from, for example, an air laster or a rubber-based soft material.

The protective wall (38) is preferably fitted around the periphery of the opening (37), and a narrow gap is preferably provided between the protective wall (38) and the footboard (33). This is because if the tread plate (33) is tilted in a state where the protective wall (38) and the tread plate (33) are in contact with each other, the protective wall (38) is likely to deteriorate due to friction or the like, and durability is difficult. On the other hand, the provision of this gap makes it easier for foreign matter to enter, but as shown in FIG. 19, the protective wall (38) is formed into a substantially triangular shape protruding upward from the periphery of the opening (37), and the protective wall ( Grooves (39) and (39) that circulate the protective wall (38) are provided on the slope of 38) so that the protective wall (38) increases flexibility. In the illustrated embodiment, two grooves (39) (39) that circulate around the protective wall (38) are formed on the inner side surface and the outer side surface of the protective wall (38), respectively. Thereby, the protective wall (38) has high flexibility.For example, when the protective wall (38) is pushed from the upper side, the protective wall (38) bends toward the tread plate (33), and the gap Is buried. Accordingly, it is possible to prevent foreign substances and the like from being mixed.
In addition, although it is desirable to form a groove | channel in both the inner surface and outer surface of a protective wall (38), you may provide it in any one. Moreover, it can replace with a groove | channel and can also be set as the structure which makes thickness thin.
