The guide groove (26) is a vertical groove extending in the vertical axis direction so as to slide the protrusion (25) when the chair is raised and lowered. (26a) and a lateral groove (26b) that extends in the circumferential direction from the end of the longitudinal groove (26a) that faces the protrusion (25) when the chair is positioned at the highest position (P8) but does not reach the entire circumference. When the chair (2) is positioned lower than the highest position (P8), the protrusion (25) of the locking mechanism (25A) is engaged with the longitudinal groove (26a), thereby the chair ( Hold 2) as a frontal posture toward the main body (3) so that it cannot rotate, When the child (2) is raised to the highest position (P8), the protrusion (25) is allowed to enter the lateral groove (26b) from the end of the vertical groove (26a) so that the chair is in the front posture. It is in the point comprised so that it can rotate to the boarding / alighting attitude | position which faces from the side .
As a result, when the chair is at the highest position where the exerciser's exercise is not scheduled due to the height adjustment mechanism, the exerciser places a burden on the legs and legs because the chair turns to the side of the exercise equipment. And can easily sit on a chair. Then, if the chair is rotated while being seated on the chair and the height is adjusted at a position facing the main body, the user can easily enter an exercise posture. In addition, after the exercise is completed, the chair can be easily raised from the chair by raising the chair to the highest position and rotating the chair left or right.

According to the exercise apparatus of the present invention, since the height adjustment mechanism 20 constituting the gas spring is provided, the support shaft for supporting the bottom 8 of the chair by operating the operation lever 8a to release the lock. The chair 20a can be moved up and down freely between the lowest position P7 and the highest position P8 .

The connecting means 4 is configured to be able to extend and contract so that the distance between the chair 2 and the main body 3 can be adjusted as will be described later. In addition, while supporting the exercise apparatus 1 at the end of the base member 4a, a leg ring 15a for moving the base member 4a relative to the base member 4b is provided, and at the end of the base member 4b, the exercise apparatus 1 is provided. And a grounding seat 15b for fixing the base member 4b.

  The chair 2 has a backrest 5 and a seat portion 6, and on both sides thereof, a handle 7 is provided at a position higher than the seat portion 6 for an exerciser who leans on the backrest 5 to grip during exercise. Yes. A support leg 9 having a height adjusting mechanism, which will be described later, is provided on the bottom 8 of the chair 2 and the lower end of the support leg 9 is fixed to the base member 4a. In addition, although the case where the decorative cover 10 is provided in the lower part of the support leg 9 is shown in the illustrated example, the decorative cover 10 is not essential.

  Further, as shown in FIG. 2, the exercise apparatus 1 is provided with an ear-type pulse sensor 16 that detects the pulse of the athlete, and a sensor connection portion 7 a in which a cable of the pulse sensor 16 is provided at the tip of one handle 7. It is configured to connect to. A pulse detection signal is transmitted to the display panel 14 described later by wireless communication means (not shown) provided in the handle 7. However, the present invention is not limited to this mode, and the cable of the pulse sensor 16 may be directly connected to the display panel 14.

  The main body 3 is provided on the base member 4b, and includes a pedal 11 on a crank extending from the rotating shaft on both the left and right sides, and a load is applied to the rotating motion of the rotating shaft by a magnetic brake mechanism or the like. A loading means is provided. The load means is configured to vary the exercise load on the pedal 11 in three stages, for example, “strong”, “medium”, and “weak”. A support arm 12 that has a plurality of joints 13 and bends toward the chair 2 is provided at the top of the main body 3, and the tip of the support arm 12 supports the back surface of the display panel 14. . In the illustrated embodiment, a bracket 3a is fixed to the top of the main body 3, a bracket 14a is fixed to the back surface of the display panel 14, and the support arm 12 includes at least a first arm 12a and a second arm 12b. The bracket 3a and the first arm 12a of the main body 3 via the first joint 13a, the first arm 12a and the second arm 12b via the second joint 13b, and the second arm 12b. The bracket 14a of the display panel 14 is configured to be refractable by rotating around the horizontal axis via the third joint 13c. The bending angle of each joint 13 of the support arm 12 is easily changed by manual operation, and when the external force is not applied by manual operation, the bending angle is maintained. For this reason, the display panel 14 can be disposed at a position relatively close to the chair 2 by bending the support arm 12 toward the chair 2 by manual operation, and the support arm 12 is arranged in the opposite direction. The display panel 14 can also be moved away from the chair 2 by bending it. That is, the position and posture of the display panel 14 in front of the chair 2 can be adjusted by the bending operation of the support arm 12. In particular, according to the illustrated configuration, the chair 2 of the display panel 14 is selected by selecting the refraction angle of the support arm 12 with respect to the bracket 3 a of the main body 3 and the refraction angles of the plurality of arms 12 a and 12 b constituting the support arm 12. And the height position of the display panel 14 can be arbitrarily set, and the third panel 13c can be set to an optimum angle so that the display panel 14 faces the line of sight of the athlete. In this embodiment, as shown in the figure, the support arm 12 has a plurality of joints 13. However, the support arm 12 may have any structure as long as it can be bent toward the chair. For example, an articulated arm that freely bends at an arbitrary position may be used.

  FIG. 3 is a front view of the display panel 14. The display panel 14 includes an annular operation unit 17 and an exercise information display unit 18 disposed inside the annular operation unit 17. The annular operation unit 17 is provided with selection buttons 17a, 17b, and 17c for selecting a desired exercise load from among three stages of exercise loads, and a reset button 17d for resetting the display state of exercise information. The exercise information display unit 18 also displays various information such as the selected exercise load, the exercise time, the heart rate detected by the pulse sensor 16, the speed obtained from the rotational speed of the crank when pedaling, the distance, and the calories consumed by the exercise. It is configured to be able to display exercise information. In the lower part of the display panel 14, an opening is provided so that a hand can be inserted between the annular operation unit 17 and the exercise information display unit 18, and the annular operation unit 17 corresponding to the opening edge of the display panel 14 is positioned or oriented. The grip part 19 at the time of operating is comprised.

  FIG. 4 is a diagram for explaining an operation for changing the position and orientation of the display panel 14. As shown in FIG. 4, when the joint 13a is rotated, the support arm 12 swings in the arc direction indicated by the arrow A1, and when the joint 13b is rotated, the support arm 12 swings in the arc direction indicated by the arrow A2. The pivoting action of the joints 13a and 13b is combined, and the support arm 12 can move the display panel 14 in a wide range and various ways on the front side of the chair 2. For example, the display panel 14 is moved to a relatively high position (position P1). ) Or at low positions (positions P2 and P3). In other words, since it is possible to move in the front-rear direction at a predetermined height position or in the up-down direction at a predetermined front-rear position, the height position of the display panel 14 and the distance from the chair 2 can be determined by the athlete. It can be set to an appropriate state. When the joint 13c is rotated, the display panel 14 swings in the direction indicated by the arrow A3. Therefore, the angle of the display panel 14 positioned by adjusting the support arm 12 can be adjusted (attitudes of P2 and P3). In this configuration, the display panel 14 can be directed to the athlete sitting on the chair 2 from any position. Therefore, the athlete sitting on the chair 2 can arrange the display panel 14 in a state that is easily visible during exercise by grasping the grip portion 19 of the display panel 14 and adjusting the position and posture appropriately. The visibility of 14 is improved.

  In the case of the illustrated example, two joints 13a and 13b are provided to bend the support arm 12 toward the chair 2, but one joint may be provided. However, in order to position the display panel 14 in a wide range, it is preferable that there are many joints that bend the support arm 12, and it is preferable to configure the support arm 12 having at least two joints. In the present embodiment, two joints 13a and 13b are provided to bend the support arm 12 toward the chair 2, and one joint 13c is provided to adjust the angle of the display panel 14 separately from this. If the number of joints of the support arm 12 is increased, the angle of the display panel 14 can be adjusted by the combined operation of these joints, so that it is not necessary to provide a dedicated joint for adjusting the angle of the display panel 14.

  FIG. 5 is a diagram for explaining an operation for adjusting the distance between the chair 2 and the main body 3. For example, the chair 2 can be moved closer to or away from the main body 3 by moving the base member 4a in the direction of the arrow B1. That is, the mutual interval between the chair 2 and the main body 3 can be adjusted within the range of the maximum interval (P4 state) and the minimum interval (P5 state), and an appropriate interval (for example, P6) according to the physique of the athlete. It is possible to set to (state). The connecting portion between the base members 4a and 4b is provided with a locking means 4c such as a spring knob, and after positioning the space between the chair 2 and the main body 3, the base members 4a and 4b are fixed to each other by the locking means 4c. This prevents the distance between the chair 2 and the main body 3 from changing during exercise. In addition, although the case where the chair side base member 4a is advanced and retracted toward the main body side base member 4b is shown in the illustrated example, the present invention is not limited to this, and the main body side base member 4b is advanced and retracted toward the chair side base member 4a. You may let them.

  In the above-described interval adjustment operation, the locking means 4c provided at an intermediate position between the chair 2 and the main body 3 is operated. Therefore, when the display panel 14 is positioned between the chair 2 and the main body 3, the operation is hindered. there is a possibility. Therefore, for example, as shown in FIG. 5, if the support arm 12 is lifted so that the display panel 14 is retracted from the front position of the chair 2, the display panel 14 does not hinder the operation and the adjustment operation is smoothly performed. It can be performed.

  The extendable base members 4a and 4b constituting the connecting means 4 can bring the chair 2 close to the main body 3 up to the position indicated by P5 in FIG. 5, and the support arm 12 of the display panel 14 is shown by a chain line in FIG. Since it can be folded as shown, the exercise apparatus 1 can be packed or stored in a compact state.

  FIG. 6 is a diagram for explaining an operation for adjusting the height of the chair 2. The support leg 9 of the chair 2 is provided with a height adjusting mechanism. For example, the locked state is released by pulling up the operation lever 8a provided on the bottom 8 of the chair 2, and the height position of the chair 2 is set to the highest position (P8). Can be adjusted freely within the range of the lowest position (position P7) and can be set to an appropriate height position (for example, the position P9) according to the physique of the athlete. When the operation lever 8a is returned in a state where the height is appropriate, the height adjustment mechanism is again locked.

  In the above height adjustment operation, the exerciser may be slightly bent forward. In that case, if the display panel 14 is positioned between the chair 2 and the main body 3, there is a possibility that the operation may be hindered. For example, as shown in FIG. 6, as shown in FIG. If the display panel 14 is retracted from the position, the display panel 14 does not hinder the operation, and the adjustment operation can be performed smoothly.

  FIG. 7 is a cross-sectional view showing a detailed configuration of the support leg 9 and is a view of the chair 2 as viewed from the front. The support leg 9 includes a height adjusting mechanism 20 configured by a known gas spring, and a support shaft 20 a of the height adjusting mechanism 20 supports the bottom portion 8 of the chair 2. When the operation lever 8a is operated, the lock is released and the support shaft 20a slides in the vertical direction to move the chair 2 in the vertical direction. Outside the height adjusting mechanism 20, a slide tube 21 fixed to the bottom 8 of the chair 2 and a base tube 22 fixed to the base member 4a on the chair side are provided. The slide tube 21 is housed inside the base tube 22, and slides up and down inside the base tube 22 as the chair 2 is moved up and down by the height adjusting mechanism 20. Configure.

  FIG. 8 is a diagram showing the configuration of the slide tube 21 and the base tube 22. The side surface of the slide tube 21 is provided with a guide groove 26 including a vertical groove 26a extending in the vertical direction and a horizontal groove 26b formed in the circumferential direction from the lowest point of the vertical groove 26a. The lateral groove 26b is formed by cutting the side surface of the slide tube 21 by about ½ round, and constitutes a junction that is connected to the vertical groove 26a at the center position of the circumferential length. On the other hand, the base tube 22 is provided with a mounting portion 23 with a female screw for mounting a spring knob 24 having a projection 25 at the tip. Then, the slide tube 21 is housed inside the base tube 22, and the male screw member of the spring knob 24 is screwed to the mounting portion 23 so that the protrusion 25 is inserted into the guide groove 26, thereby guiding the slide tube 21. The protrusion 25 is engaged with the groove 26. Since the upper end of the slide tube 21 is fixed to the bottom portion 8 of the chair 2 and the lower end of the base tube 22 is fixed to the base member 4a, the chair 2 in the exercise apparatus 1 is engaged by the engaging action of the protrusion 25 and the guide groove 26. Direction is regulated. Note that the spring knob 24 retracts the protrusion 25 from the guide groove 26 by pulling the spring knob 24 against the internal spring in a state where the male screw member is screwed to the mounting portion 23, and the slide tube 21. The base tube 22 can be rotated or inserted / removed.

  FIGS. 9A and 9B are views showing the operation of the slide tube 21 and the base tube 22, wherein FIG. 9A shows a state in which the protrusion 25 is engaged with the vertical groove 26a, and FIG. 9B shows that the protrusion 25 is in the horizontal groove 26b. The engaged state is shown. First, as shown in FIG. 9A, in the state in which the protrusion 25 is engaged with the longitudinal groove 26a, the slide tube 21 is completely restricted from rotating around the vertical axis, as indicated by an arrow C1. Movement is allowed only in the vertical direction in which the vertical groove 26a is formed. When the operation lever 8a is operated as described above and the chair 2 is positioned at the lowest position (P7) in FIG. 6 by the height adjusting mechanism 20, the slide tube 21 is in the lowest position, and the projection 25 is formed in the longitudinal groove 26a. Engage in the vicinity of the upper end of the. When the operation lever 8a is operated from this state and the chair 2 is raised to the highest position (P8) in FIG. 6 by the height adjusting mechanism 20, the slide tube 21 is in the highest position, and the protrusion 25 is the highest in the vertical groove 26a. It is located at the lower point and faces the lateral groove 26b. The chair 2 is configured to face the main body 3 in a state in which the protrusion 25 is engaged with the vertical groove 26a. Therefore, in this state, even if the height of the chair 2 is adjusted, the chair 2 is held in a posture (motion posture) facing the main body 3 and does not rotate.

  As described above, when the protrusion 25 is engaged with the lowest point of the vertical groove 26a connected to the horizontal groove 26b, the slide tube 21 is allowed to rotate around the vertical axis along the horizontal groove 26b. Accordingly, the slide tube 21 can be rotated in any direction around the left and right as indicated by an arrow C2 in FIG. 9B. At this time, when the slide tube 21 is rotated by a certain angle or more, the protrusion 25 is separated from the joining point of the vertical groove 26a and the horizontal groove 26b and is engaged only with the horizontal groove 26b. Is completely regulated, and the chair 2 does not descend even when the operation lever 8a is operated. In a state in which the slide tube 21 cannot move up and down, the slide tube 21 can be turned about 90 degrees in the left-right direction, and the chair 2 can be turned to a posture facing the side of the exercise equipment 1 (a boarding / alighting posture). Therefore, only when the chair 2 is at the highest position by the height adjustment mechanism 20, a boarding / alighting support mechanism that is rotatable between the exercise posture and the boarding / alighting posture is configured.

  FIG. 10 is a diagram illustrating an example of the state in which the chair 2 is rotated about 90 degrees at the highest position in the exercise apparatus 1. In the exercise apparatus 1, the highest position of the chair 2 is a position where the exerciser does not plan to exercise, and is a position for assisting the exerciser's sitting or standing movement, and the chair 2 is about the highest position. By turning 90 degrees, as shown in FIG. 10, the chair 2 faces the side of the exercise apparatus 1 at a relatively high position, and at this time, the chair 2 is in a state in which it cannot be lowered. Even if the legs and legs are weak, it is possible to sit on the chair 2 relatively easily without imposing a burden on the legs, and further, the chair 2 is rotated as it is to face the main body 3. If you adjust the height, you can easily get into the exercise posture. Further, after the exercise is finished, the chair 2 is raised to the highest position and the chair 2 is turned to the left or right, so that the user can easily stand up from the chair 2. At this time, since the handle 7 is provided on both sides of the chair 2, there is no risk that the athlete falls when the chair 2 rotates, and it is safe. On the other hand, when an exerciser sits in a state where the chair 2 is in the getting-on / off posture toward the side of the exercise equipment 1, the chair 2 is turned toward the main body 3 to start pedaling exercise. When the chair 2 is lowered from the highest position by the height adjusting mechanism 20 and set to a predetermined height, the chair 2 is held unrotatable as described above.

  When the display panel 14 is positioned between the chair 2 and the main body 3 when the chair 2 is rotated as described above, the operation may be hindered. For example, as shown in FIG. By lifting the support arm 12 and keeping the display panel 14 retracted from the front position of the chair 2, the display panel 14 does not hinder the chair 2 from rotating, and the chair 2 can be smoothly rotated. Can be moved.

  In the above description, the lateral groove 26b of the slide tube 21 is formed about 1/2 of the circumferential side surface so that the chair 2 can rotate about 90 degrees in the left and right directions from the state where the chair 2 is opposed to the main body 3. Although the case where it is formed by cutting to a certain extent is illustrated, it may be configured to be able to rotate about 90 degrees only in one of the left and right directions. In this case, the lateral groove 26b of the slide tube 21 is about 1 / What is necessary is just to make it the structure which cut and formed about 4 rounds and connected the vertical groove 26a to the edge part of the horizontal groove 26b. The rotation angle of the chair 2 can be arbitrarily adjusted by changing the design of the length of the lateral groove 26b.

  In the above description, the guide groove 26 is provided in the slide tube 21 and the protrusion 25 is provided in the base tube 22. However, the guide tube is provided in the base tube 22 and the slide tube 21 is associated with the guide groove. A mating protrusion may be provided. However, in that case, the horizontal groove is formed in a mode of being connected to the upper end of the vertical groove.

  As described above, in the exercise device 1 according to the present embodiment, the chair 2 includes the height adjustment mechanism 20, and when the chair 2 is at the highest position by the height adjustment mechanism 20, the chair 2 moves left and right around the vertical axis. Therefore, the chair 2 can be turned to the side of the exercise apparatus 1 at the highest position. Therefore, when an exerciser sits on the chair 2 and enters an exercise posture, the exerciser is narrow between the chair 2 and the main body 3 if the chair 2 is set to the highest position and is directed to the side of the exercise apparatus 1. There is no need to put a body into the space, and the chair 2 is in the highest position, so it can be seated comfortably without placing a burden on the legs. Then, if the chair 2 is rotated to the position facing the main body 3 with the sitting posture, and the height is adjusted, there is no risk of falling over the connecting means 4 and entering the exercise posture safely. I can go. Further, after the exercise is finished, the chair 2 is raised to the highest position and turned so that the chair 2 is directed to the side of the exercise apparatus 1, so that there is no possibility of falling over the connecting means 4, and from the exercise posture easily. You can stand up safely and leave your seat.

  In the above-described embodiment, the chair 2 is raised to the highest position and the chair 2 is rotated so as to be directed to the side of the exercise apparatus 1. However, the spring knob 24 attached to the base tube 22 is as described above. Since the protrusion 25 can be retracted from the guide groove 26, the chair 2 can be rotated at an arbitrary height position by using the function of the spring knob 24. Hereinafter, this aspect will be described in detail.

  FIG. 11 is a cross-sectional view showing a detailed configuration of the spring knob 24 provided on the support leg 9 of the chair 2, and the function of the spring knob 24 allows the chair 2 to be rotated between an exercise posture and a getting-on / off posture at an arbitrary height position. It is a figure explaining the structural example of the boarding / alighting support mechanism made free. As described above, the slide tube 21 is fixed to the chair 2 side, and the base tube 22 is fixed to the base member 4a. The slide tube 21 is inserted inside the base tube 22, and the chair 2 by the height adjustment mechanism. The inner tube 21a that slides with respect to the base tube 22 is formed as the tube moves up and down, and the base tube 22 forms the outer tube 22a with respect to the inner tube 21a. Further, the spring knob 24 constitutes a locking mechanism 25A for engaging the projection 25 provided at the tip with the guide groove 26 of the slide tube 21, and a fixing member 23a fixed to the mounting portion 23 of the base tube 22, A locking shaft 25a provided at the tip with a projection 25 inserted through the longitudinal groove 26a of the guide groove 26 provided in the slide tube 21a through the fixing member 23a and the base tube 22a, and the projection 25 is always the guide groove 26. A spring 25b that urges the locking shaft 25a toward the inside of the slide tube 21 and a knob 24a provided at the tail end of the locking shaft 25a are provided. With this configuration, as shown by an arrow C3 in FIG. 12, the locking shaft 25a is moved in the axial direction against the urging force of the spring 25b via the knob 24a, and the protrusion 25 is retracted from the vertical groove 26a. The slide tube 21 can be rotated in the circumferential direction with respect to the base tube 22 as shown by an arrow C4 in FIG. 12, and the chair 2 is rotated at an arbitrary height position from the exercise posture to the side of the exercise apparatus 1. It is possible to turn to the boarding / alighting posture facing the.
