Description

  The present invention relates to a training machine mainly for aerobic exercise.

  Currently, aerobic exercise such as step exercise and running exercise is expected to promote health. Many of these aerobic exercises are difficult to perform regularly for reasons such as time constraints and weather, so various training machines have been proposed.

  If the machine of patent document 1 is demonstrated to an example, as shown in FIG. 8, the basic frame 1 of a basic skeleton, the support frame 2 standingly arranged in the front-end part of the basic frame 1, and the support frame 2 will be movable. A supported left and right pendulum system 3, a left and right vertical resistance system 4 that applies a load to the vertical operation of each pendulum system 3, and a horizontal resistance system 5 that applies a load to the horizontal operation of each pendulum system 3 Have.

  Each pendulum system 3 includes a pivot shaft 6 supported by the support frame 2 and upper and lower horizontal links 8. It consists of front and rear vertical links 9, and a substantially central portion of the upper horizontal link 8 and an upper end portion of the front vertical link 9 are rotatably connected to the pivot shaft 6, and from the upper end portion of the front vertical link 9 An L-shaped handle 10 is extended.

  A rear vertical link 9 is pivotally supported at the rear end of the upper horizontal link 8, and both ends of the lower horizontal link 8 are at the lower ends of the vertical links 9. The shaft is pivotally supported. A foot pad 11 for placing the soles of the trainees is fixed to the rear end of the lower horizontal link 8.

  Each vertical resistance system 4 includes a vertical resistance link 12 rotatably connected to a front end portion of an upper horizontal link 8, a crank member 13 rotatably connected to a lower end portion of the vertical resistance link 12, and a basic structure. Comprising a pulley system 14 having an electronically controlled generator attached to the frame 1, the crank member 13 is connected to the pulley system 14, and the braking force and the deceleration force against the vertical movement in the upper horizontal link 8. Giving resistance.

  The horizontal resistance system 5 includes a swing link 15 extending forward from the left and right pivot shafts 6, and an auxiliary resistance link 16 pivotally connected to the pivot shaft 6 via the swing links 15. A horizontal resistance pulley 17 rotatably connected to each auxiliary resistance link 16, and a speed-up pulley and a flywheel 18 (not shown) connected to the horizontal resistance pulley 17 via a belt 19, The link 15 rotates in conjunction with the front vertical link 9. Therefore, a resistance force is applied as an eddy current brake by the flywheel 18 to the horizontal movement of the front vertical link 9.

  When the user puts the soles on the left and right foot pads 11 and performs the running motion by operating the left and right handles 10 back and forth, the upper horizontal link 8 rotates and the pendulum system 3 starts the pendulum motion. At this time, the resistances of the vertical resistance system 4 and the horizontal resistance system 5 are added to the pendulum system 3.

JP2008-161685

  However, although the machine of Patent Document 1 is an improved fitness apparatus with user-defined motion, basically, the foot pad 11 is circulated by the pendulum movement around the pivot shaft 6 of the pendulum system 3. The running trajectory is not an ideal elliptical trajectory as in actual running, and may give the user a feeling of strangeness.

  In addition, the horizontal motion is also a pendulum motion, so it is not suitable for the “slip motion” which is said to be effective for deep muscles and hip range of motion. In addition, since the vertical link employs a crank mechanism, it requires a large amount of force and knack for starting, and is difficult to use for beginners and care prevention purposes.

  The present invention has been made to solve the above-described problems of the prior art, and an object of the present invention is to provide a training machine that can perform aerobic exercise efficiently without a sense of incongruity.

  Therefore, the present invention includes a pair of left and right steps movably supported by a base frame, and a load loading device that applies a load to the operation of each step, and a leg portion with a user's sole placed on each step. A training machine that performs the above-described exercise, wherein each step is supported by the base frame with a left and right link mechanism that is vertically expandable and contractible, and each link mechanism is provided slidably in the horizontal direction of the base frame, Each of the steps described above is characterized in that it can operate in a reciprocal manner by drawing one of an elliptical trajectory, a vertical trajectory, and a horizontal trajectory.

  According to the present invention, the above-described operations of the left and right steps are realized not by the pendulum movement as in Patent Document 1, but by the expansion / contraction operation and slide movement of the link mechanism. Therefore, the user can reasonably perform an ideal running motion operation such as actual running, a step motion operation such as stepping up and down, and a pedestrian walking motion operation.

  In one aspect of the present invention, the rails formed on the left and right side frames of the base frame are provided with slide members that are slidable in the horizontal direction, and each link mechanism is rotated by one of the slide members. A pair of links whose base end portions are freely supported, and arms whose base end portions are rotatably supported by the other slide member and generate a load of the load load device according to each operation of the step The tip of one link is pivotally supported on the outer periphery of the arm, and the step is rotatably supported by the tip of the other link and the arm. However, it is characterized in that it operates by drawing each of the trajectories in accordance with the rotation operation and the slide movement in the both links and the arm.

  Further, another aspect includes a support frame that supports the load applying device and a pair of left and right handles that are rotatably supported by the support frame, and the sliding movement of the other slide member and each of the handles. It is characterized in that the rotation is linked.

  According to this aspect, if the operation of pushing the leg forward while grasping the handle and pulling it forward is repeated alternately, the arm and back muscles can be trained in addition to the legs.

  According to the present invention, it is possible to provide a training machine that can efficiently perform aerobic exercise without a sense of incongruity.

<Base frame 24 / support frame 27>
As shown in FIGS. 3A and 3C, the base frame 24 is connected between the front and rear side frames 25 with a connecting pipe 30, and a driving gear is connected to the front and rear side frames 25 of the connecting pipe 30. A slide rail 34 having a T-shaped cross section is formed on the inner surfaces of the left and right side frames 28. A pair of front and rear slide members 36 each having a T-shaped groove portion are slidably attached to each slide rail 34, and as shown in FIGS. 3B and 3D, the front and rear slide members 36 are attached to the front and rear slide members 36, respectively. Each link mechanism 21 is supported.

  Here, as shown in FIGS. 3A and 3D, the left and right slide members 36 arranged on the rear side are connected to the end portions of the chain 37.38 before and after each drive gear 32 is wound. Therefore, the left and right link mechanisms 21 slide in opposite directions. A pair of bearings 39 are formed on the front slide member 36. On the other hand, as shown in FIG. 4, the rear slide member 36 has a support shaft 41 that pivotally supports the base end portion of the drive arm 40, and a support disposed in the opposite direction to the support shaft 41. The piece 42 is welded. A shaft member 43 is welded to the outer periphery of the base end portion of the drive arm 40, while one end portion of the connecting arm 44 is pivotally supported at the other end portion as shown in FIGS. Has been.

  The support frame 27 has a substantially gate-shaped gate frame 45 erected on the front side frame 25 of the base frame 24, and a connection (not shown) that connects the front side frame 25 and the gate frame upper frame 46. A beam, an I-shaped frame 48 erected on the auxiliary frame 26, and a connecting plate 49 on which the load-loading device 22 is arranged by connecting the connecting beam, and a base end portion supported on the upper end of the I-shaped frame 48. A U-shaped U-shaped frame 50, a handrail pad 53 disposed rearward from both ends of the U-shaped frame 50, a connecting bar 54 that connects both ends of the U-shaped frame 50, a connecting bar 54, and a connecting beam And a beam 52 between them.

  Both end portions of a rotating shaft (not shown) disposed in the connection bar 54 are exposed from the connection bar 54, and a cylindrical portion 55 is attached. The lower end portion of the handle 56 is welded to the upper and outer periphery of the cylindrical portion 55, while the other end portion of the connecting arm 44 is welded to the lower and outer periphery of the cylindrical portion 55. It is made slidable. A pair of drive gears 57 are rotatably supported on the inner surface of the central portion of the I-shaped frame 48, and four bearings 58 are formed on the portal frame upper frame 46. Each bearing 58 is supported by a rotatable pulley 59 and a pair of drive gears 60 that always rotate the pulley 59 in a fixed direction by a one-way clutch 47, and when one of the drive gears 60 rotates synchronously with the pulley 59. The other drive gear 60 reverses with the pulley 59. The chain 61 is wound around the drive gears 57.60, and one end portion of the connecting member 62 is connected to the end portion of the chain 61.

<Link mechanism 21>
Each link mechanism 21 is configured to be vertically extendable on each side frame 28 of the base frame 24, and as shown in FIGS. 3 (b) and 4, an outer side formed on a front slide member 36 is provided. A short link 63 whose base end is rotatably connected to the bearing 39, a long link 64 whose base end is rotatably connected to the inner bearing 39, and a shaft member 43 welded to the drive arm 40. And a stopper 66 for restricting the rotation range of the long link 64. The stopper 66 is rotated around the support piece 42 and the vicinity of the upper end of the long link 64. It is pivotally supported.

  Specifically, the distal end portion of the short link 63 is pivotally supported by a shaft 67 fixed to the upper and outer periphery of the rotational arm 65, while the distal end portion of the long link 64 is the rear portion of the step 68. It is rotatably supported with respect to a cylindrical portion 70 formed on the bottom surface. The front end portion of the rotating arm 65 is bent in an L shape, and the other end portion of the connecting member 62 is rotatably connected as shown in FIGS. Further, the front end portion of the step 68 is pivotally supported by a bearing 71 at a substantially central outer periphery of the rotation arm 65, and the front and rear of the step 68 are supported by the long link 64 and the rotation arm 65. In this step 68, as shown in FIG. 6, a foot pad 72 for placing the sole of the user can be attached.

  Such expansion and contraction of the link mechanism 21 will be described. First, when step 68 on one side is stepped on, each link 63.64 and rotating arm 65 are folded as shown in FIGS. That is, when step 68 is stepped on in the state of FIG. 5 (a), as shown in FIGS. 5 (b) and 5 (c), the turning arm 65 and both links 63.64 are turned downward, and the front and rear slides are moved. The member 36 is indicated by an arrow P.D. in FIG. It slides in the Q direction and shifts to the folded state of FIG. At this time, since the rotation arm 65 rotates downward, the chain 61 is pulled, and one drive gear 60 rotates in the direction C in FIG.

  Next, when step 68 on the opposite side is stepped on in the state of FIG. 5D, the drive gear 60 on that side (the other side) rotates in the C direction, so that one drive gear 60 moves in the D direction in FIG. The rotating arm 65 on one side is lifted upward through the chain 61. At this time, since the front end portion of the short link 63 is rotatably supported by the shaft 67 fixed to the upper and outer circumferences of the rotation arm 65, the front and rear slide members 36 are indicated by arrows R.P. By sliding in the S direction, both links 63.64 rise to restore the state shown in FIG.

  One end portion of an elastic member (spring member) 73 is also connected to the tip end portion of the rotating arm 65, and the other end portion of the elastic member 73 is both end portions of the bar 74 disposed at the front end portion of the auxiliary frame 26. It is connected to. As a result, the pivot arm 65 is restrained from excessive movement by the engagement force due to the elastic deformation of the elastic member 73 with respect to the movement in the direction of arrow G in FIG. The elastic member 73 also serves as a tensioner for the chain 61.

<Load loading device 22>
The load loading device 22 is configured as an eddy current brake, and as shown in FIGS. 1 and 2, a pair of left and right support plates 75 screwed to a connecting plate 49 and a shaft that is rotatable between the support plates 75. A brake disc 76 made of a supported copper plate and a brake driver 77 that excites an electromagnet (not shown) to give resistance to the rotation of the brake disc 76, and includes control means (not shown) that transmits a voltage signal to the brake driver 77. Built-in.

  In other words, the brake driver 77 energizes and energizes the electromagnet with a current amount corresponding to the voltage signal transmitted from the control means, and gives resistance to the rotation of the brake disk 76. At this time, the pulley (not shown) that rotates synchronously with the brake disk 76 and the pulley 59 of the portal frame upper frame 46 are wound with the belt 78 as shown in FIG. Resistance is given to the rotation in the direction of arrow C. Therefore, the rotation of the rotation arm 65 in the vertical direction and the arrow G. Rotational resistance of the brake disc 76 is added to the movement in the H direction, which causes a load on the operation in the same direction of both steps 68. This load amount is adjusted by changing the voltage value transmitted by the control means by operating the panel 79 in FIG.

  Note that the load load device 22 is not limited to the eddy current brake. For example, a similar load can be obtained even with a power generation brake, and power supply from the outside can be made unnecessary. Moreover, these compound load apparatuses may be sufficient.

<Training operation example>
Hereinafter, a training operation example using the machine 20 will be described. Here, as shown in FIG. 6, a cover is attached to the support frame 27 of the machine 20, a foot pad 72 is attached to the step 68, and a control means for transmitting a voltage signal is incorporated in the cover. To do. FIG. 6 shows an operation example of a running exercise (jogging exercise) among the training operation examples.

  During training, the user sets a desired load amount by operating the panel 79 after placing the soles on the left and right foot pads 72. First, the step movement will be described. The left and right foot pads 72 are alternately stepped on by grasping the handrail pad 53 and stepping on. According to this operation, the left and right link mechanisms 21 are alternately expanded and contracted in FIGS. 5A to 5D, that is, the rotating arm 65 and both links 63.64 are alternately rotated in the vertical direction. The left and right steps 68 reciprocally reciprocate on the vertical trajectory of 7 (a). At this time, a load of rotation resistance of the brake disc 76 is applied, so that the same training as the step up / down can be performed by repeating the stepping motion. Therefore, it is possible to perform step exercise without preparing a platform, and to burn body fat by aerobic exercise and muscles of the legs and hips.

  Next, the cross-country pedestrian walking will be described. The operation of pushing the leg forward while holding the handle 56 and pulling it forward (horizontal sliding) is repeated alternately. At this time, the left and right pivot arms 65 are moved to the arrows G. In order to slide in the H direction, the left and right steps 68 reciprocate reciprocally on the horizontal trajectory in FIG. Since the load of the rotational resistance of the brake disk 76 is also applied to this sliding movement, by repeating the steering operation and the leg movement, a pedestrian walking movement similar to running on a snowy field with a ski can be performed, and aerobic In addition to burning body fat due to exercise, you can also train deep muscles, greater gluteal muscles, and hip range of motion. You can also train your arm and back muscles by pulling the handle.

  Lastly, the running exercise (jogging exercise) will be described. As shown in FIG. 6, the user performs the running leg operation while holding the handle 56 and placing both legs on the foot pad 72. Here, when one foot pad 72 is stepped forward with a leg so that the link mechanism 21 is folded, the link mechanism 21 naturally slides in the direction of arrow G, and the link mechanism 21 of the opposite foot pad 72 is moved. Slides in the direction of arrow H while standing up. Next, when the opposite foot pad 72 is stepped on in the same manner, the link mechanism 21 slides in the direction of arrow G, and the link mechanism 21 of the opposite foot pad 72 slides in the direction of arrow H while standing up.

  At this time, as shown in FIG. 7 (c), the left and right steps 68 reciprocally circulate on the same elliptical orbit as the actual running orbit. If it is repeated while resisting the load of resistance, an ideal running exercise operation becomes possible, and the efficiency of aerobic exercise and the like can be improved. Such a running motion operation is not a pendulum motion as in Patent Document 1, but the running motion is reproduced by the expansion and contraction motion and the slide movement of the link mechanism 21, so that even if the handle 56 is not pushed and the momentum is not applied, the step is performed. Orbits an elliptical orbit. Therefore, the user only has to swing his / her arms in accordance with the movement of the handle 56, and even a beginner can train without difficulty, which is suitable for the purpose of preventing care.

  As a result, the machine 20 can freely perform step exercise, cross-country gait walking, and running exercise, and the combined exercise allows various muscles such as arms, back, legs, and waist at the same time as aerobic exercise. Can train. In addition, by switching exercise motion continuously without interrupting exercise, it is possible to eliminate the repetition of monotonous motion motion, and the user can continue without getting tired of training, and this can also contribute to improving training efficiency. .

  The present invention is not limited to the above-described embodiment. For example, the rotation speed of the brake disc 76, the slide range of the slide member 36, and the like are detected by the detection means, and the load resistance is adjusted based on the detected value. You can also. As an example of the application, if the speed and the movable range are limited, it is possible to perform training with increased safety so that an excessive load is not applied to the body. Further, in each of the motion operations, an example of an operation in which the handle is gripped has been described, but it is also possible to perform a motion motion without gripping the handle.
