Description

  According to the present invention, it is possible to accurately and quickly set an optimum load amount for a training machine user based on the improvement of the training machine, more specifically, based on a prescription by a doctor or the like. The present invention relates to a personalized automatic adjustment system in a training machine capable of automatically adjusting the position of a seat or the like of the training machine so as to suit the physique, and a stepless load adjustment mechanism used therefor.

  In recent years, when various types of training are performed at fitness clubs, specialists such as doctors, dietitians and trainers individually diagnose the health status of the target person and the type of exercise and load value required. Prescribing the amount of exercise, etc., a detailed exercise menu is set, for example, the amount of load to be applied to increase muscle strength is set.

  By the way, a training machine is used for such strength-strengthening training, and generally, a method of applying a load to muscles by lifting a heavy weight is often employed.

  Specifically, the weight is slid in the vertical direction against gravity and lifted and lowered. For example, a plurality of weights having a predetermined weight such as “5 kg” and “10 kg” are arranged to obtain a target weight. In this way, a latch or the like such as a pin is inserted, and the load is changed depending on the number of weights that are hooked, and the load is adjusted when lifting (for example, see Patent Document 1).

  However, in such a weight adjustment structure, there is a complaint that the load can be set and changed only in stages in units of weight of each weight, and the load corresponding to the intermediate weight cannot be finely adjusted.

  Therefore, in order to widen the range of load weights that can be set, there is a problem that a large number of weights are inevitably required, and furthermore, since each weight is separated and independent, it is mistaken when operating. There was also a risk of pinching fingers.

In addition, training machines are often shared by multiple people, and the physiques differ from user to user.Therefore, before training, users of the machine's seatboard, backboard, handle, bar, grip, etc. The position of the member in contact with the body had to be matched to the sitting height, arm length, leg length, etc., and this work was time consuming and laborious and was very troublesome.

  Next, an embodiment of a load adjustment mechanism used in the automatic adjustment system of the present invention will be described below.

[First embodiment of load adjustment mechanism]
A first embodiment of a load adjusting mechanism for a training machine used in the system of the present invention will be described with reference to FIGS. As shown in FIG. 1, the load adjusting mechanism of the present invention is employed in a training machine that can apply a load to muscles by reciprocating a weight 1.

  In configuring the load adjusting mechanism in the present embodiment, first, a threaded hole 11 is formed through the weight 1, and the long pendulum frame 8 is inserted into the threaded hole 11 with the screw shaft 6A screwed therein. Store.

  Further, a pivot 81 protrudes from one end (right side in FIG. 2) of the pendulum frame 8 in a direction perpendicular to the screw shaft 6A, and the pendulum frame 8 is mounted on the pivot 81 as a swing axis. It is configured to be swingable. Accordingly, the weight 1 performs a seesaw motion along a circular orbit about the pivot 81.

  Then, the weight 1 is slid in the longitudinal direction of the pendulum frame 8 by rotating the screw shaft 6A forward and backward using the weight mover 3 to increase or decrease the span between the center of gravity of the weight 1 and the pivot 81. it can.

  As shown in FIG. 3, a screw nut member 6B screwed to the screw shaft 6A is attached to the weight 1, and the weight 1 is slid in the longitudinal direction of the pendulum frame 8 by forward and reverse rotation of the screw nut member 6B. Thus, the span between the center of gravity of the weight 1 and the pivot 81 can be increased or decreased.

  In this way, the amount of moment when the weight 1 swings can be changed. In other words, if the span is increased to make the weight 1 a distance away from the pivot 81, the amount of moment on the pivot 81 can be increased. Therefore, the rotational drag of the pivot 81 can be increased or decreased in proportion to this moment amount.

  As a result, it is possible to adjust the tensile resistance of the belt member 9 that is wound around the outer periphery of the pivot 81. Therefore, the load can be freely changed according to the desire of the training machine user. With such a configuration, it is not necessary to replace the weights 1 one by one, the load can be adjusted only by adjusting the moment amount, and the load can be finely adjusted.

  In this embodiment, since the weight 1 performs a seesaw exercise along a circular trajectory, the load decreases as it is lifted upward, so that it matches the physical condition, training location, and training content of the training machine user. Suitable for those that should gradually reduce the strain on the muscles.

  At this time, as shown in FIG. 4, the cam shaft is used by swinging the trajectory of the weight 1 from the horizontal level in a vertically symmetrical manner (a range of about 45 degrees in the vertical direction in this figure). The transmission load can be made substantially uniform.

  In this embodiment, the control motor 31 can also be employed as the weight mover 3 that automatically rotates the screw shaft 6A. The weight 1 is moved by rotating the screw shaft 6A at high speed, and the load is quickly adjusted. Can do.

  Furthermore, in this embodiment, the guide groove 13 can be formed in the weight 1 so as to be slidable along the guide rail 84 of the pendulum frame 8, and the weight 1 rotates in the frame and falls off accidentally. Can be prevented and safety can be improved.

  Furthermore, in this embodiment, the screw shaft 6A can be a ball screw, and the movement can be performed smoothly by reducing the frictional resistance.

[Second embodiment of load adjustment mechanism]
Next, a second embodiment of the present invention will be described with reference to FIGS. In this embodiment, an insertion hole 12 is provided through the weight 1, and the guide shaft 82 is inserted into the insertion hole 12 and is stored in the long pendulum frame 8 (see FIG. 5).

  A support shaft 83 is formed on the outer surface near the upper end of the pendulum frame 8 in a direction orthogonal to the guide shaft 82, and the pendulum frame 8 is configured to be swingable about the support shaft 83 as a rotation axis. To do.

  Further, a screw nut member 6B is pivotally provided on the outer surface of the pendulum frame 8 so as to swing freely, and the screw shaft 6A is screwed into the screw nut member 6B.

  Next, as shown in FIGS. 6 and 7, the tilt angle of the pendulum frame 8 can be changed via the screw nut member 6B by forward and reverse rotation of the screw shaft 6A or the screw nut member 6B. At this time, although the screwing position fluctuates in an arc shape, the mounting base end portion of the screw nut member 6B is rotatable, and the screw shaft 6A is also supported by the rotatable fulcrum 51. Can be linked smoothly.

  Therefore, the load component of the vertical component of the weight 1 can be increased or decreased in proportion to the inclination angle of the pendulum frame 8. That is, in the case of FIG. 6, since the vertical component becomes large, the load becomes large. In the case of FIG. 7, since the vertical component becomes small, the load can be made small.

  By changing the inclination angle in this way, the tensile resistance of the belt member 9 fixed to the weight 1 can be adjusted. Unlike the first embodiment, the training machine of this embodiment can obtain a constant load because the weight 1 reciprocates along a straight track.

  Also in this embodiment, similarly to the first embodiment, the guide groove 13 is formed in the weight 1 so as to be slidable along the guide rail 84 of the pendulum frame 8, and the screw shaft 6A is used as a ball screw. Of course, it is naturally possible to employ a control motor 31 that automatically rotates the screw shaft 6A.

[Training machine example 1]
The stepless load adjustment mechanism configured as described above can be applied to, for example, a training machine (rear Delt etc.) for strengthening the pectoral muscles and upper arm muscles as shown in FIG. A tensile drag can be applied through the belt member 9 when the bars are brought inward.

  The training machine can be configured so that the position of the back plate and the sitting height can be adjusted as appropriate, and the reader means 2 is installed as a control panel so that the optimal load amount and / or the training machine user can be set. By holding the memory medium M on which the physique data is recorded, it is possible to automatically adjust to an appropriate load and position. The control panel can also be provided with a manual position adjustment switch, load display means, and the like.

Further, the adjustment system and the adjustment mechanism can be applied to a training machine (abcrunch etc.) for strengthening the abdominal muscles and pectoral muscles as shown in FIG. In addition, a tensile drag can be applied via the belt member 9. In this training machine, the back plate position and the sitting height position can be appropriately adjusted as described above.
