FIG. 1 is a perspective view showing the entire structure of a lumbar strength training apparatus according to the present invention, and FIG. 2 is a front view showing a partially broken lumbar strength training apparatus. 3 and 4 are schematic side views showing how the lumbar strength training apparatus is used. This lumbar strength training device (hereinafter simply referred to as a training device) 1 includes a horizontal base portion 3 placed on an installation surface 2 such as a chair or a floor, and a base portion 3 disposed above the base portion 3. On the other hand, the upper surface is composed of a seating portion 4 and the like that can change elastically, and muscle strength training around the waist is performed by the user (user) placing the waist on the upper surface of the seating portion 4 and exercising.

  In the training apparatus 1, the base portion 3 and the seating portion 4 are formed in a disk shape in plan view, and the seating portion 3 is provided so as to be horizontally rotatable with respect to the base portion 3. On the upper surface side of the base portion 3, a movable portion 7 which is formed in a disk shape having the same diameter as the base portion 3 in plan view and is arranged on the same axis as the base portion 3 is placed and supported so as to be horizontally rotatable. .

  The base portion 3 and the movable portion 7 are connected to each other in a rotatable manner via a connecting shaft (rotating shaft) 6 extending in the vertical direction at the center of each other. In addition, a ring-shaped slide member 8 made of a synthetic resin material, a bearing or the like that is slippery and waterproof is provided on the outer peripheral side between the opposing surfaces of the base portion 3 and the movable portion 7. The slide member 8 receives a downward load applied to the seat portion 4 and smoothly rotates the movable portion 7 horizontally with respect to the base portion 3.

  The seat portion 4 is a bag-like member capable of press-fitting air (gas) made of elastically deformable rubber or synthetic resin material, and has a slightly larger diameter than the movable portion 7 in a state where the air is press-fitted and inflated. It is shaped to be a disk. On the upper surface of the seating portion 4, there is provided an airframe supply portion 9 having a check valve structure for injecting and discharging air in a sealable state, while the lower surface of the seating portion 4 is in a state of being in contact with the surface. Thus, it is attached and fixed to the upper surface of the movable part 7 with an adhesive or the like.

  In addition, you may attach and fix the seating part 4 to the upper surface of the movable part 7 so that attachment or detachment is possible. Specifically, the seating intention part 4 is detachably attached and fixed to the movable part 7 by providing a velvet fastener and a concave-convex fitting part on the lower surface of the seating part 4 and the upper surface of the movable part 7.

  As a result, the seating part 4 can be easily injected with air from the gas supply part 9 even with a simple pump such as an air pump for toys, and swells so as to be elastically deformable when the gas is press-fitted and sealed. The upper surface of the seating part 4 can be made elastically variable with respect to the base part 3.

  Moreover, since the seating part 4 can adjust gas pressure easily via the gas supply part 9, according to the purpose of training, it uses the cushion-like use mode shown by the solid line in FIG. In addition to being able to be used, it can be used in a sitting posture and a supine posture in any case. In the ball-shaped usage mode, it is possible to effectively perform training performed while supporting the lower back portion to be placed more unstable, training with a person standing on the ball-shaped upper surface, and the like.

  In addition, by detachably attaching the seating part 4 to the movable part 7, when the seating part 4 is replaced with another seating part 4 having a different size or shape according to the training purpose, the seating part 4 is repaired. This makes it possible to respond quickly.

  Further, since the upper surface of the seating portion 4 is configured to be elastically changed by the gas pressure with respect to the base portion 3, the base portion 3 and the seating portion 4 are connected by a compression spring or the like, and the upper surface of the seating portion 4 is connected to the base portion 3. Compared with the conventional one that is elastically changed, the number of parts is small, and a simple and low-cost structure can be achieved, and the manufacture can be facilitated.

  Further, the seating portion 4 and the base portion 3 are waterproofed to enhance the waterproofness of the training device 1. Accordingly, the bathtub 11 and various facilities shown in FIG. 4 can be installed and used in water, and exercise using buoyancy can be promoted in water to further improve the training effect. In addition, the training apparatus 1 used underwater performs waterproofing on the whole parts and makes the connection part of the base part 3 and the movable part 7 waterproof as shown in the illustrated example. You may make it the structure which provides the drain hole which takes in / out water.

  The training device 1 configured as described above is placed on the installation surface 2 such as a floor or a chair when used in a sitting position, or on the installation surface 2 such as a floor or a bed when in a supine posture in FIG. It can be used with the device placed on its back and the device placed on the lower back, and the body can be moved back and forth, left and right and the center of gravity can be moved, or one leg can be raised and lowered alternately. As shown in FIG. 4, it is placed on the installation surface 2 of the bathtub 11, and the upper body or waist is moved back and forth, left and right, and the arms and legs are alternately raised and lowered while the user is sitting on the waist. Training can be done easily.

  In such a use, the training device 1 has the seat portion 4, the base portion 3 and the movable portion 7 arranged on the same axis, so that the posture determination when placing on the installation surface 2 is always the same posture. Therefore, convenience during use is improved. In addition, the seating portion 4 can move the upper surface up and down in response to a change in the load within the range of the limit compression amount in accordance with the compression amount of the internal air due to the load variation of the weight applied to the upper surface. In addition, the seat 4 is elastically deformed in the direction of movement of the lower back according to the degree of unbalance of the posture in the sitting posture or the supine posture of the user, so that it has a restoring force and repeatedly moves up and down or swings in the entire circumference. In addition, the lower back can be supported in an unstable manner.

  In addition, the disc-shaped seat 4 rotates horizontally with respect to the base 3 so that it can smoothly turn left and right without causing excessive stress in the waist, and the upper body and pelvis can be moved. Stretching exercises that are twisted can be performed more freely. Accordingly, the user can effectively turn the trunk in a sitting position, a supine position, a standing position, etc., and thus can stimulate muscles deep in the body and activate their functions.

  In addition, the training device 1 configured as described above is a soft cushion that is elastically deformed by press-fitting and sealing a gas, compared to a conventional structure in which the seat 4 is supported by a mechanical spring material on a flat movable plate. Can be contacted. This makes it easier to move the pelvis and the like in a direction that is conscious and causes instability due to the movement in the tilt direction, making the muscle stimulation more complex and further enhancing the training effect.

  Moreover, since the training instrument 1 can adjust the gas pressure of the seating part 4 easily and can attach or detach the seating part 4 with respect to the base part 3, the seating part 4 according to the objective of various training and a user's liking. It can be used with increased convenience and the versatility of the instrument can be improved.

  Further, as shown by a dotted line in FIG. 2, the seat portion 4 can be provided with a plurality of protrusions 12 on the upper surface. In this case, the protrusion 12 can prevent the waist from slipping, and the waist pressure can be reduced. An effect can also be obtained. In the illustrated example, the seating portion 4 has a separate part structure from the movable portion 7. However, for example, the seating portion 4 and the movable portion 7 are integrally formed by a processing means for molding a silicon rubber material or the like. If it is made to support so that rotation with respect to 3 is possible, a structure can be simplified.
