Description

  The present invention relates to stretching and health equipment for daily use or exercise.

  Traditionally, many exercise field devices are aimed at strengthening the abdominal muscles, while the reverse vector stretching exercise, such as a fight where two people fold their arms back to back, are also used for posture correction purposes, neck and shoulders, It is effective to relieve the stiffness of the back and increase the flexibility, and such purposes include stretching the back on a foam roller placed on the floor and rolling it with a roll.

Such a stretch device is mainly used by the user to bend back from the back to the convex bench bed, and is required to move and vigor during use, and the bench bed is generally fixed. There is not much flexibility in the form of stretch itself.

The present invention has been made paying attention to such a current situation, and the user can perform limb-free dorsal lumbar muscle extension like the above-mentioned support that suits individual needs without any concern from the usual standing posture. In addition to being able to be performed safely in a natural and compact manner, it provides easy and multifunctional stretching and exercise equipment by adding massage and bending / extending functions of the upper limbs.

  In order to achieve the above object, the device of the present invention has an appropriately shaped cushion holder 2 with the receiving surface holding the back and waist, facing the back and back, and the user's waist side horizontally and horizontally in the frame 1 standing on the left and right. The shaft 3 is supported so as to be able to recline A.

  The frame 1 is provided with support grips 4 on the sides of the forearms of the user 10 who are seated on the holder 2 in a standing position, and a gas spring 5 is interposed between the frame 1 and the holder 2 structure. The operating state of the gas spring 5 is applied to the stand-by side of the holder (FIG. 1) when the gas spring 5 is in the fully extended state, and the user springs the upper body against the holder 2 to deepen the reclining angle A. 5 is shortened, and the reaction force, that is, the restoring force B to the normal position of the back holder 2 is gradually increased.

  The reclining A angle of the back holder 2 can be appropriately adjusted, and a headrest 6 and the like are arbitrarily provided.

   A rope jumping rope 8 and a belt that can support and support the hips from the back when the gripping part 7 is provided on the back holder 2 and facing the holder 2 are adjusted between the side frames 1 and detachable. Set.

  According to the above configuration, the user 10 naturally faces the back holder 2 (FIG. 1), grips the grip 4 and stretches the arm and leans against the back holder 2 so that the back holder 2 is centered on the horizontal side axis 3 of the waist. Turns reclining A. In other words, an office worker can control the lower back of the body easily and safely while maintaining a normal posture or with a low-centered compact warp (Fig. 3) while supporting the grip even for users of physically weak people such as women and the elderly. Yes.

  Due to the return device, the back holder 2 is almost upright in a free normal state before use (FIG. 1), and its repulsive force is small, so that the initial reclining operation for depositing the upper body is easy. Also, each time reclining A is deepened, the restoration, that is, the repulsive force B gradually increases and is proportional to the increase in the load that the user entrusts to the body. Easy and smooth.

Various selections and adjustments are possible, such as the material and shape of the back holder 2, the attachment of the headrest 6, the reclining A angle and the return force, and the body strength and safety of the user 10 according to the user's needs can be free. Can stretch.

A massage function such as vibration and rolling can be arbitrarily and effectively applied to the holder 2 by any means such as manual or electric operation.

  Various exercise applications are possible by using the structure and restoration form of the device. For example, by supporting the back and lower back with a belt or rope 8 (Fig. 6), the holder 2 can be stimulated by the holder 2 or the optional handle 7 etc. Closed left, right or both arms flexing and stretching movement C is possible. The rope 8A can be wound around the head pins 16, 16A and the like to have an appropriate length and used as a rope for jumping rope. FIG. 9 shows an example of upper and lower side shoulder arm movement D using a convex handle 7A.

  Also, the arm is extended on the frame 1 or the grip 9 whose shape is changed and the body is supported to extend the trunk released from gravity (Fig. 8), the upper arm is bent and extended (Fig. 7), and the grip 4A. The prone movement (FIG. 10) etc. which hold | gripped can be performed.

  The instrument height is changed (not shown) according to the user's body, and a variable height base, a block 18 and the like are arranged. The block 18 can also be applied to lifting and lowering movements as shown in FIG.

  An example of an embodiment of the present invention will be described with reference to the drawings that are simply illustrated. There is a seat back-shaped holder 2 that receives the back and back of the user 10, and the reclining A operation is not hindered on both sides of the user. The wooden frame 1 is erected, and the rotation axis 3 between the two is placed around the waist center of the user 10 backed by the holder 2 (FIG. 1), and is arranged horizontally and horizontally and on each of the frames on both sides. A grip 4 is provided.

  A gas spring 5 is interposed between the back surface 11 of the back of the holder and the rear lower part 12 structure of the frame. When the instrument is in a free normal state, the gas spring 5 is extended normally or optionally with a stopper (not shown) to hold the backrest surface upright (FIG. 1), and the gas spring 5 is shortened as the reclining degree is deepened (FIG. 3). The attachment positions 11 and 12 of the gas spring 5 to the holder 2 and the frame 1 can be arbitrarily adjusted.

  Reference numeral 13 denotes a stopper for adjusting the reclining angle as needed, and the position can be changed up and down behind the frame. 14 is a damper for reducing the impact.

The holder 2 is composed of a frame material with flexibility, a pad resin having a suitable cushioning property, a hollow material, a mesh material, and the like so as to hold the back and back of the surface. A side seat is optionally attached (not shown).

A plurality of head pins 16 are arbitrarily provided on the front outer surfaces of the left and right frames 1 at the high side between the hips, and a rope 8 having a ring shape 17 on both ends is hung on the left and right sides so that the stretch can be freely attached between the left and right sides (FIG. 6).

The holder 2 is provided with a relaxing effect by adding vibration and a rolling function to an arbitrary position by hand and electric power as seen in a general massage chair. 5 and FIG. 4-C, the holder 2 is stretched by contacting the holder 2 with a polygonal shaft 16 provided on the frame 1 during reclining, and can be easily swung by the front / rear operation E of the lever 17. This is an example to enjoy. Various vibrations can also be obtained by interposing a speed change mechanism such as a gear or a toothed belt.

At the center of the upper end of the holder 2, a detachable and angleable headrest 6 is detachable.

FIG. 7 shows an example in which a metal pipe 1A is used as a frame material. The gas spring 5 is used for reclining restoration, but a leaf spring or a torsion coil spring may be used. In addition, for example, a height adjustment function suitable for each user is added such as a warp where the foot is always grounded. A variety of useful applications may be considered based on the gist without limiting the scope of the attachment / detachment, holding structure, and the like to this example.
