Description

[Detailed Description of the Invention] This invention relates to a sports and health equipment for maintaining health and relieving stress through moderate exercise, mainly in daily life.

Conventionally, this type of sports health equipment has been designed in such a way that a swinging coil spring is fixed to a fixing bolt erected above the center of a fixed suction cup, and a punching ball is attached to the upper end of the coil spring. was.

However, when in use, the fixed suction cup is fixed to a horizontal surface such as a desk or table, and the ball can only be hit from the front with a raised bone to relieve some stress. Since adjustment is not possible, it is extremely difficult to select the suction and fixing position of the fixed suction cup so that the ball is at the ideal height, that is, the ball and the user's arm are in the same horizontal position. This resulted in players hitting the ball in an awkward position, which halved the effectiveness of the exercise.

This idea was devised to eliminate the above-mentioned drawbacks. A swinging coil spring with a punching ball removably attached to the upper end is mounted on a fixed base for height adjustment. By removably fixing the ball through the support rod and lower support rod, the ball can be freely adjusted to the ideal height, allowing you to always hit the ball in the correct posture, thereby increasing the effectiveness of your exercise. To provide a sports and health equipment that not only doubles the number of exercisers, but also allows various types of exercise to be carried out moderately, and that can reliably maintain health and relieve stress.

An embodiment of this invention will be described below with reference to the drawings.

As shown in the figure, the sports health equipment of this invention consists of a fixed base A, a lower support rod B for adjusting the first height, an upper support rod C for the second height adjustment, a coil spring D for swinging, and a ball for punching. It is composed of five members: E.

As shown in FIGS. 1 to 3, the fixing base A is made by bending a round pipe into a planar rectangular shape, and installing a slightly wider reinforcing plate 2 at one end on the bottom surface of the outer frame 1. A reinforcing plate 3 having a width about the width of the reinforcing plate 2 is installed slightly on the other end side of the center, and triangular reinforcing plates 4 are provided at each corner of the other end.

In addition, on the upper surface of the longitudinal center portion of the reinforcing plate 2 of the outer frame 1,
A cylindrical fixing part 6 to which a tightening bolt 5 (for example, a knob bolt made of plastic or the like) is loosely screwed is provided at the upper end, and the entire inside of the outer frame 1 except for this fixing part 6 is provided with a cylindrical fixing part 6. is a treadboard 8 made of wood or the like with a carpet 7 or other fabric affixed to the top surface.
are provided to be placed on each of the reinforcing plates 2, 3.4,
The footboard 8 is screwed to each of the reinforcing plates 2 and 4 together with rubber non-slip devices 9 placed on the bottom surface of each of the four corners of the outer frame 1.

As shown in FIGS. 1, 2, and 4, the lower support rod B is attached to the upper end of a tubular body 10 whose diameter is slightly smaller than that of the fixing part 6 of the fixing base A. A mounting part 12 is formed with a small diameter and a dividing groove 11 is provided on each of the opposing circumferential walls, and a tightening fixture 13 is attached to this mounting part 12 to tighten and fix the upper support rod C in an appropriate position. It is being

This tightening fixture 13 fixes a substantially U-shaped tightening ring 15 having a through hole 14 bored at each open end, and inserts a tightening bolt 16 into each through hole 14 of this tightening ring 15. A long nut 18 with an operating lever 17 is loosely screwed onto the threaded side of the insert.

In this case, a rotation preventing protrusion 19 protruding from the shaft portion of the tightening bolt 16 near the bolt head is fitted into a notch 20 provided in one of the through holes 14 of the tightening ring 15, so that the locking bolt 16 can be loosened. Care is taken to prevent the tightening bolt 16 from idling during tightening.

As shown in FIGS. 1, 2, and 4, the upper support rod C has a threaded rod 22 forced inside the upper end of a tubular body 21 whose diameter is slightly smaller than that of the attachment portion 12 of the lower support rod C. is attached to.

As shown in FIGS. 1 and 2, the coil spring D has a coil wire 23 having a wire diameter of about 4.5 m/m, and the diameter of the coil wire 23 is gradually increased from the lower end to the upper end to form a substantially long inverted cone. A locking protrusion 24 is provided at the upper end portion of the coil wire 23 so that the upper end of the coil wire 23 projects upwardly and extends in a crosswise manner toward the cylindrical core.

This locking protrusion 24 is provided with a curved locking portion 25 substantially on the cylindrical center for reliably locking the locking rod (described later) of the ball E, and this locking portion 25 is A rising piece 26 is provided at the tip to facilitate the locking operation to the locking rod.

As shown in FIGS. 1 and 5, the ball E has an approximately S-shaped or approximately S-shaped recess 27 recessed downward in a planar approximately keyhole shape from a circular portion and a rectangular portion on the lower inner surface. A substantially Z-shaped steel locking rod 28 fixes a horizontally buried rubber fixture 29, and an air vent hole (not shown) for inflating and deflating is provided in the upper part. There is.

In this way, the lower support rod B is moved up and down within the fixed part 6 of the fixed table A by using five members such as the fixed base A, the lower support rod B, the upper support rod C, the coil spring D, and the ball E. Insert freely,
Further, the upper support rod C is similarly inserted into the lower support rod B so as to be vertically movable, and the coil spring D is removably fixed to the upper end threaded rod 22 of the upper support rod C by means of screwing means. A locking rod 28 of a mounting tool 29 for the ball E is detachably attached to the upper end locking protrusion 24 of the ball E.

Since this device is constructed as described above, when in use, the tightening bolt 5 of the fixing base A and the tightening fixture 13 of the lower support rod B are operated to tighten the lower support rod B and the upper support rod. By moving C up and down to match the ball E to the height of the user's arm, the user can perform arm bending and stretching movements as if hitting the ball E from the front with a raised bone while resting on the fixed table A.

Similarly, by aligning the ball E with the height of the user's waist, the user lifts the knee of the foot forward and kicks the ball E, thereby performing a knee-kick exercise that strengthens muscles such as the thighs and abdomen. Not only can you do this, but you can also turn your back to ball E and hit ball E with both hands at the same time, causing ball E to bounce back.
You can rotate both arms backwards to straighten your spine and hit your hips by touching your lower back.

Furthermore, various foot movements can be easily performed while holding the lower support rod B or the upper support rod C with both hands.

By doing these kinds of exercises in moderation, you can reliably maintain your health.

In addition to being able to perform various types of exercise in moderation, when you are mentally fatigued or mentally unstable, by hitting the ball E with all your might, you are sure to relieve the mental stress that has built up in your body. can be achieved.

Moreover, by inserting the lower support rod B into the fixed part 6 of the fixed base A so that it can move up and down, and by inserting the upper support rod C into the lower support rod B so that it can move up and down, the ball E and the user can Ball E can be adjusted to the ideal height in two stages so that the user's arm is in the same horizontal position, so regardless of the height of the user, the ball E can always be struck in the correct posture. This can double the effects of various types of exercise.

In addition, since the outer frame 1 of the fixed base A is made of round pipe,
By placing the arch of your bare foot on the outer circumferential surface of the outer frame 1 and stepping on it many times, not only will your internal organs and blood circulation be significantly improved, but you will also be able to easily relieve fatigue and further maintain your health. .

Furthermore, the fixed base A and the lower support rod B, which are structural members of this invention,
, upper support rod C, coil spring D, ball E, etc. are assembled so that they can be disassembled from each other, making it extremely convenient for packing, transporting, storing, etc. Moreover, coil spring D with ball E attached can be used as a shoulder hitter. This is possible, and if only the ball E is used, it can also be used as a ball for normal games or sports.

In addition, as a tightening fixture 13, a tightening bolt 16 is provided through the open end of a substantially U-shaped tightening ring 15, and a long nut 18 with an operating lever 17 is loosely tightened on the threaded side of the bolt 16. If the control lever 17 is rotated to tighten the tightening ring 15, not only can the height of the ball E be easily adjusted, but also the upper support rod C can be securely fixed.

As explained above, with this invention, you can always hit the ball with the correct posture, which not only doubles the effect of exercise, but also allows you to do various exercises in moderation and maintain your health. At the same time, it has great practical effects, such as being able to reliably relieve the mental stress built up in the body, being disassembleable, convenient for packaging, transporting, and storing, and having a wide range of uses. .
