Description

  [Technical Field] The present invention relates to a movable seat strength training machine for strengthening lower limbs and other muscle strengths in a strength training machine in which an elderly person or the like (hereinafter referred to as a patient) whose muscle strength has declined increases power.

  The conventional apparatus discloses a multi-exercise machine including a frame, a backrest, a seat, a frame body, a locking portion, a protruding member, a V-shaped arm, a base, a front arm, a weight portion, a footrest pad portion, a rear arm, and the like. .

In the conventional apparatus, the seat is turned upward by about 20 degrees, and the V-shaped arm is opened 45 degrees. Therefore, when the knee flexion angle is 65 degrees, the arm with the weight is 90 degrees. The load torque is maximized, and there is an effect that sufficient strength training is possible even when training with a small knee flexion angle.
However, the conventional device does not have a structure in which the seat is tilted forward in order to easily get on and off, and the height of the seating surface is high so that the toes do not touch the floor during training. It was difficult.

When the latch 32 is inserted into one of the plurality of small holes 36, the arm upper portion 29a is fixed at an appropriate position, and the starting position of the pad 15 is adjusted.
The pad position adjuster 28 adjusts and determines the start angle of the arm 29 and the start position of the pad 15 when the pad 15 is mounted on the patient's lower leg. The pad 15 is moved to a position away from the seat portion 5c so as not to become a problem, and is hooked at that position.

The load mechanism 2 is connected to the input mechanism 1 and provided.
The load mechanism 2 includes a weight frame 42, a weight 16 made of an iron plate such as 1 Kg and 2 Kg, a holding rod 37 that holds the weight 16 so as to be movable up and down, a rope 17 whose base end is connected to a weight hanging rod 38, A weight retaining bar 38 penetrating vertically in the center of the weight 16, a weight adjusting pin 39 for retaining the weight 16 on the weight retaining bar 38, a pulley 40 for hanging the rope 17, and the rope 17 between the rollers And a pair of rollers 41 for controlling the direction of forward and backward movement of the rope.

  The input mechanism 1 is connected to the weight frame 42, the tip of the rope 17 is fixed to the pad position adjuster 28 of the input mechanism 1, and the rope 17 is supported by the pulley 40 and the pair of pulleys 41 while the rope 17 is being stretched. Is done.

The rope 17 sandwiched between two paired pair rollers 41 is stretched around the paired rollers 41 to the pulley 40, and the pad position adjuster 28 is moved together with the movement of the pad 15 in the front upward direction or the downward direction. Pulls the rope 17 sandwiched between the pair of rollers 41 and lifts the weight 16, so that the weight 16 becomes a load regardless of which direction the pad 15 moves.
While the weight 16 is being lifted, the weight of the weight 16 is applied to the pad 15 and becomes a load of leg extension movement.

When using the first embodiment, first, the pad 15 is lifted upward and moved to a position away from the seat 5, and is hooked at that position by the pad position adjuster 28. The pad 15 is transferred to the patient. Make sure that it does not interfere with operation
Next, when the direction of the seat 5 is set to the boarding / alighting position, the knob 23d is pulled, and the seat 5 facing the front is turned to the boarding / alighting position, so that it is automatically fixed by the rotation fixing unit 13. .

The seat 5 is set to a predetermined tilt angle by the tilt support mechanism 6.
That is, the handle 11 provided on the telescopic member 10 is operated to adjust the length of the telescopic member 10 so that the seat 5 is tilted forward.

The gas spring 12 urges the seat 5 in the forward tilt direction, and brakes a sudden tilting movement of the seat 5 to slowly tilt the seat 5.
The patient sits on the seat 5c tilted forward. After sitting down, the fixing belt 20 is hung on the thigh and the thigh is fixed to the seat 5.
Next, the handle 11 is operated, the length of the telescopic member 10 is reduced and adjusted, and the seat 5 is tilted backward. The seat 5 is changed to a rearward tilting posture while being slowly rotated by the braking action of the telescopic member 10.

  Subsequently, the seat 5 is rotated in the front direction and is automatically fixed in the front direction by the hand operation positioning plunger 23.

  Next, when changing and adjusting the starting position of the pad 15 according to different physiques for each patient, the pad 15 is lowered and brought close to the front part of the lower leg, and the upper position 29a and the flat plate 35 are positioned with the pad position adjusting tool 28. The relationship is adjusted and latched, and the starting position of the pad 15 is set.

  The patient puts the front of the lower leg on the pad 15 in a horizontal state, and the patient applies force to the leg so that the leg extends from the bottom to the top, raises the pad 15 (= forward movement), and performs the leg extension movement. Start.

The weight 16 is lifted according to the distance that the pad 15 has moved forward, and the weight of the weight 16 becomes a load on the patient.
A plurality of weights 16 are stacked and pulled up as the pad 15 is lifted. The number of rising weights 16 is adjusted by appropriately selecting the position of the insertion hole 43 of the weight adjusting pin 39. If the weight adjustment pin 39 is inserted into the lower insertion hole 43 and the number of weights 16 is increased, the training load increases. If the weight adjustment pin 39 is inserted into the upper insertion hole 38 and the number of weights 16 is decreased, training is performed. The load of becomes smaller.
Next, remove the force of the leg and return the leg from the extended position to the bent position (= reverse movement). At this time, the weight 16 is lowered, returned to the original position, and stacked, and the load becomes zero.

  Next, the leg is extended again, and the pad 15 is pushed forward and upward. The forward and backward movements described above are performed a predetermined number of times or repeatedly for a predetermined time, and exercise for strengthening the strength of the quadriceps and other muscles is performed by extending the legs.

  When the leg is bent, the pad position adjuster 28 is released and the pad 15 is released from the lower leg. Next, the pad 15 is rotated downward. The patient places the back of the lower leg on the front upper side of the pad 15 located below.

Next, the assistant lifts the pad 15 forward and upward together with the lower leg applied to the front of the pad 15 to lock the pad position adjuster 28.
After the above setting, the patient moves the lower leg from the upper side to flex the leg and moves the pad 15 downward. When the pad 15 moves downward, the weight 16 is lifted, and the weight of the weight 16 becomes a load on the patient.

When the bending motion is finished, the pad position adjuster 28 is released, the pad 15 is rotated downward, and the lower leg is removed from the front upper side of the pad 15.
Next, the pad 15 is moved upward, separated from the seat 5 and hooked.
Next, the handle 11 is operated, the length of the telescopic member 10 is adjusted to extend, and the seat 5 is returned to the horizontal posture.
The seat 5 is rotated and fixed to the right boarding / alighting position, then the seat 5 is tilted forward, the patient is lowered from the chair 3, and the training is completed.

In the second embodiment shown in FIG. 6, a biasing tool 45 is additionally installed on the support 9 of the first embodiment.
A winding portion of the urging tool 45 is fitted on the seat shaft 44, one end is applied to the seat frame 14, and the other end is applied to the support tool 9. The biasing tool 45 has a biasing force in a direction in which the seat 5 is tilted forward, and is a torsion spring in a specific example.

  The tilt support mechanism 6 and the rotation fixing unit 13 are provided, and the present invention can be applied to a movable seat strength training machine 19 that is easy to get on and off the seat 5 and has a simple configuration.

It is the right view which leaned forward the seat which concerns on Example 1 of this invention.
