Description

  The present invention relates to exercise equipment, and more particularly to exercise equipment for squats.

  In recent years, training equipment for the elderly has been sold, because even elderly people can have a healthy life if they have a certain level of muscle strength. Such training equipment is the same as training equipment for general gymnasiums, and when installed in an elderly facility, it is not used under high load conditions, so the maximum weight is reduced. It is often said.

  In various types of exercise, the muscles of the foot are particularly important, and training equipment such as a so-called leg press and leg extension is often used.

  As a method for strengthening leg muscle strength, a squat exercise may be simply performed, and a device for assisting the squat exercise has also been proposed (for example, see Patent Document 1).

JP2012-095996A

  However, when the elderly perform squat exercise, it is difficult to exercise with correct motion due to joint pains such as knees and hips before strengthening the muscle strength of the legs, or because the trunk muscle is insufficient, the posture is maintained. In some cases, it was difficult to use with existing exercise equipment.

  In view of such a current situation, the present inventor has developed an exercise apparatus that enables an elderly person to perform a squat exercise with peace of mind, and has achieved the present invention.

  In the exercise equipment for squat exercise according to the present invention, a base including a step plate on which a user's foot is placed, a support column standing on the base, and a seat plate swingable in the vertical direction by an elastic body, A state in which the upper body of the user seated on the seat plate is pulled upward by the traction means by attaching the end portion of the traction means to the column. It is what makes a user perform a squat exercise.

Furthermore, the exercise device of the present invention is also characterized by the following points.
(1) The pulling means has a sheet body to be applied to the user's back, and a longitudinal stretch body that pulls the sheet body by connecting one end to the sheet body, and the other end of the stretch body Is attached to the column.
(2) The seat plate is provided at the distal end of a seat plate arm whose base end is rotatably mounted on a support column, and a guide rod that penetrates a coil spring as an elastic body that swings the seat plate in the vertical direction is provided. The guide plate is urged upward by pivoting one end of the guide rod to the middle of the seat plate arm and pivoting the other end to the base.
(3) The support column is provided with a rod-like handle that protrudes in parallel with the direction of the rotation axis of the arm for the seat plate that is rotatably mounted on the support column. The support column is parallel to the handle and above the handle. A rotating rod mounted rotatably, and a telescopic body of the traction means is hung on the rotating rod, and an end of the telescopic body is mounted on the connecting portion of the handle and the column.

  With the exercise device of the present invention, an elderly person can exercise squat with peace of mind.

It is a perspective view of the exercise device concerning the present invention. It is explanatory drawing of the use condition of the exercise device which concerns on this invention. It is explanatory drawing of the use condition of the exercise device which concerns on this invention.

  The exercise device for squat exercise according to the present invention includes a means for supporting the upper body of the user and a seat plate that can swing in the vertical direction to compensate for insufficient leg force.

  Specifically, as shown in FIG. 1, the exercise device of the present invention includes a base 10 provided with a step plate 11 on which a user's foot is placed, a column 20 erected on the base 10, and an elastic body. Thus, the seat plate 30 that can swing in the vertical direction is provided, and the traction means 40 that pulls the upper body of the user upward.

  In this embodiment, the base 10 includes a central base 12 that extends in the front-rear direction, a front base 13 that is provided at the front end of the central base 12 so as to be orthogonal to the central base 12, and a rear end of the central base 12. The rear base 14 provided perpendicularly to the central base 12 has a vertically long “e” shape.

  The central base 12 is made of a metal prism, and an opening is formed through each of the front base 13 and the rear base 14 made of a metal cylindrical member, and a cylindrical member having a predetermined length is inserted through the opening. A front base 13 and a rear base 14 are provided. The center base body 12, the front base body 13, and the rear base body 14 are welded to each other. Rubber caps 15 are respectively attached to both ends of the front base 13 and the rear base 14 to prevent slipping.

  An opening through which the flat plate-like step plate 11 is inserted is provided in the central portion of the central substrate 12 between the front substrate 13 and the rear substrate 14, and the step plate 11 is inserted into the opening and screwed. Thus, the step plate 11 is mounted on the central base body 12. The step plate 11 is a wooden flat plate so that the user's feet standing on the step plate 11 do not slip.

  The support column 20 is a metal prismatic material, and is provided to stand upward from the front end portion of the central base 12. The lower end portion of the support column 20 is welded to the upper surface of the front end portion of the central base body 12, and further, the lower end portion of the support column 20 and the left and right side surfaces of the front end portion of the central base body 12 are each composed of a metal flat plate. The reinforcing plate 21 is welded to firmly integrate the support column 20 and the central base 12.

  The column 20 is provided with a bar-shaped handle 22 protruding from the column 20 in a horizontal direction at a predetermined height. That is, the handle 22 is parallel to the front base 13 and is provided so as to protrude from the left and right side surfaces of the support column 20. An appropriate elastic material such as urethane is attached to the surface of the handle for easy gripping.

  Further, the support rod 20 is provided with a rotation rod 23 in parallel with the handle 22 at the upper end portion above the handle 22. The rotation rod 23 is rotatable by being attached to the column 20 via a bearing (not shown) provided at the upper end portion of the column 20. The rotating rod 23 is also provided so as to protrude from the left and right side surfaces of the column 20.

  Further, a rod-shaped protection bar 24 is mounted on the support column 20 at a predetermined interval from the rotation rod 23 so as to be parallel to the rotation rod 23. The protection bar 24 is provided to prevent the pulling means 40 described later from coming off the rotating rod 23, and both ends of the protection bar 24 are directed toward the end of the rotating rod 23. The traction means 40 is prevented from being detached from the end of the rotating rod 23 by bending.

  The seat plate 30 is an oval plate in plan view, and an elastic sheet as a cushion is mounted on the upper surface.

  The seat plate 30 is provided at the distal end of a seat plate arm 31 having a base end rotatably attached to the middle portion of the support column 20. The base end of the seat plate arm 31 is swingable in the vertical direction by being attached to the column 20 via a pivot 32 provided in parallel with the handle 22. In particular, by making the pivot 32 and the handle 22 parallel, the ascending / descending direction of the seat plate 30 is orthogonal to the extending direction of the handle 22 made into a rod shape, and the user sitting on the seat plate 30 has the arm in front. The squat motion can be performed with the handle 22 held out.

  One end of a guide rod 33 is pivotally attached to the middle part of the seat plate arm 31, the other end of the guide rod 33 is pivotally attached to a base, and a coil spring 34 is attached to the guide rod 33. 34, the seat plate arm 31 is urged upward.

  By adjusting the length of the coil spring 34, as shown in FIG. 1, when the user is not seated on the seat plate 30, the seat plate 30 is mounted more than the base end side of the seat plate arm 31. The tip side is raised. By tilting the seat plate arm 31 in this way, when the user sits on the seat plate 30, the seat plate arm 31 can be hardly recognized as an obstacle, and the seating operation is performed. It can be made easier.

  The guide rod 33 is composed of a metal pipe, and in particular, is composed of a first pipe and a second pipe, and the outer diameter of the first pipe should be smaller than the inner diameter of the second pipe. Thus, the first pipe can be inserted into the second pipe and can be expanded and contracted. In the present embodiment, the upper end of the first pipe is pivotally attached to the middle part of the seat plate arm 31 via the upper pivot 35, and the lower end of the second pipe is pivoted to the center of the base via the lower pivot (not shown). It is pivotally attached to the base 12. In particular, the lower end of the second pipe is pivotally attached to the front end portion of the central base 12 using the reinforcing plate 21 so that the guide rod 33 can be rotated about the lower pivot.

  In the present embodiment, a coil spring 34 and a guide rod 33 for supporting the coil spring 34 are used as an elastic body for swinging the seat plate 30 in the vertical direction. However, a hydraulic damper having a function equivalent to that of the coil spring 34 is used. An appropriate biasing means such as the above may be used.

  As shown in FIGS. 2 and 3, the traction means 40 has a sheet body 41 to be applied to the user's back, and a longitudinal expansion / contraction that pulls the sheet body 41 by connecting one end to the sheet body 41. It is comprised with the body 42. FIG.

  The sheet body 41 has a belt-like shape extending from one armpit to the other armpit. The sheet body 41 is made thick by wrapping an appropriate elastic material such as urethane with an artificial leather sheet, and is placed on the back of the user. It is easy to fit.

  The stretchable body 42 is a rubber string in this embodiment. In particular, a rubber cord used in training using a rubber cord such as tube training is preferable. As shown in FIG. 1, one end of the rubber cord is attached to one end of a belt-like sheet body 41, and the other end is hung on the rotating rod 23 with the middle portion of the rubber cord suspended from the handle 22 and the support column 20. It is attached to the column 20 by being attached to the connecting portion. In the present embodiment, the rubber string is attached to the connecting portion between the handle 22 and the support column 20 by hanging the rubber string. Further, in the present embodiment, one rubber cord is substantially attached to both ends of the sheet body 41, but a plurality of rubber cords may be attached if necessary, or equivalent to the rubber cord. You may use the elastic material which has the elasticity of these.

  When using the exercise device of the present invention, as shown in FIG. 2, the user stands on the step plate 11 across the seat plate arm 31, and the seat body 41 and the elastic body 42 form a ring shape. The traction means 40 is inserted from the head so that the sheet body 41 is placed on the back, and both ends of the sheet body 41 are pulled out forward from the armpits.

  Then, the user puts the buttocks against the seat plate 30 by pushing out the arm 22 and gripping the handle 22 and bending down slightly. At this time, the upper body of the user is slightly pulled upward by the pulling means 40.

  Next, as shown in FIG. 3, when the user crouches, the action of the biasing force by the coil spring 34 and the biasing force of the expansion / contraction body 42 is received at a stage exceeding a certain level, and the operation in the rising direction is smoothly performed. Can be migrated. In particular, since the burden on the knees and hips for maintaining the posture can be reduced at the start of the standing-up motion, it is possible to make it difficult to cause pain in the knees and hips, and the squat exercise can be easily performed.

  Also, as shown in FIG. 3, when the user is in a squatting position, the hanging position of the rotating rod 23 of the rubber cord as the stretchable body 42 is almost the same as shown in FIG. The position is farther from the support column 20 than the hanging position in the standing state. That is, with the squat motion, the hanging position of the rotating rod 23 of the rubber string moves, but the rotating rod 23 rotates to enable smooth movement.

  If the rotating rod 23 does not rotate, the rubber string has a high coefficient of friction, so that the position of the hanging position does not move. This is the same as mounting at position 23. In this case, when the user is in a squatting position, both ends of the sheet body 41 of the traction means 40 enter the inside, so that the chest is tightened against the user, and the user is not breathing. There is a risk of feeling it.

  On the other hand, when the hanging position of the rotating rod 23 of the rubber cord is moved, the chest is not tightened by the sheet body 41 of the traction means 40, and the user concentrates on the squat motion. It can be performed.
