Description

Detailed description of the invention

This invention relates to a thick grip jump rope that contributes to grip strength, strengthening of the back and neck, and fixing of the wrist.

In conventional rope jumping, the grip (handle) is made of plastic or wood, and the rope is made of plastic rope, rubber cord, cloth cord, etc. The grip thickness is around 20φ, and the weight is about 100g There are many.
They are used for health promotion, endurance enhancement, and diet. On the other hand, a heavy jump rope having a weight of about 500 g to 1 kg is commercially available for training aimed at athletes. This type of skipping rope is interested in the thickness of the rope, and a rope with a thickness of 7.6φ is used. This increases the weight of the rope, which makes it easier for the rope to rotate. However, the increased centrifugal force is intended to further strengthen the muscular strength. On the other hand, a jump rope with a thick grip of about 30φ is used for a long jump rope where multiple people jump at the same time. . As described above, the conventional skipping rope is beneficial for partial strengthening of muscle strength, but its effect is limited.
In tennis competition, a thick grip racket is known to be effective because it can return a strong hit ball and stabilize the stroke. However, when a thick racket is used, the fatigue of the arm strength becomes intense, so a thin grip racket that is easy to grip and can be gripped strongly is used. In order to use a thick racket, it is necessary to strengthen the strength of the entire body including the back strength and the neck muscles in addition to strengthening the grip strength, but there are few effective instruments for strengthening this strength, and jumping rope is useful Although it was a strengthening device, there was no effective skipping device.
In tennis competition, it has been found that jumping rope with a thick grip has a useful effect not only for the above-mentioned strength enhancement but also for the tennis hitting method. Badminton uses a thin grip racket. This is because the striking method in which the wrist is used and the high-speed shuttle is driven at a steep angle by the snap force is a very powerful attack method. From a grip perspective, tennis and badminton are the opposite thickness of grip. This is because in tennis, the ball is heavy, so a heavy racket is used, and the snap hitting method cannot be used, and the opponent is far away from badminton, so a sharp hitting method is necessary. This is because it is important to return a powerful ball stably. In tennis, the batting method that makes use of the badminton wrist is the one that should be avoided the most. That is, in tennis competition, the most basic technique is to stroke with the wrist fixed. If the grip is made thicker, it is possible to suppress the snap action of freely returning the wrist, which is effective for fixing the wrist. It has been found that jumping rope with a thick grip is very effective in strengthening wrist fixation. I came. These new jump ropes for athletes have mechanical strength, wear resistance and durability, as well as rope turning and twisting resistance, as well as preventing the rope from contacting the grip edges. It is required to ensure the functionality, to fix the rope, to prevent the grip vibration during jumping rope, to optimize the construction materials used and the construction methods such as weight balance.

Problems that the device tries to solve

The key is to develop a jump rope that is much thicker than the limit of gripping force and has excellent functionality. Since it is intended for athletes' skipping ropes, it is necessary to select grip materials that are relatively lightweight and strong in strength. When the grip becomes thicker, the turning speed becomes lower than that of the conventional jump rope, and it becomes easy to be affected by the air resistance. Therefore, a weight capable of ignoring the air resistance is required. When the rope becomes thick, it becomes impossible to adopt a method of making a knot at both ends of the rope so as not to fall off the grip, and an attachment method other than the method of tying is required. Further, when the grip becomes thick, the rope comes into contact with the end of the thick grip portion, which causes unstable turning, so that a structure that does not contact is required. Further, since the increase in the weight of the rope lacks a weight balance with respect to the lightweight grip, a weight for balancing is indispensable at the other end of the rope fixing cap. This weight mounting method is also important. The combination of the mechanism and material of the connecting part that suppresses friction and wear at the connecting part of the rope and grip is also an important issue.

The present invention has a thick grip exceeding 30φ in diameter, good turning stability, no twisting of the rope, the rope and the grip can be connected in a simple and reliable way, and has excellent wear resistance and durability. The purpose is to provide a thick grip jump rope that is effective in strengthening muscle strength and fixing the wrist.

Means for solving the problem

In the present invention, a plastic material is used for the grip and the rope, and a metal is used for the connecting portion to achieve the above object. A plastic tube having various thicknesses is used for the grip, and a plastic cap (grip cap) that fits the tube is fitted to both ends of the tube. For the rope, use a flexible plastic rubber rope or a rope through a metal wire. Pass the rope through the center of the grip cap, but if you pass the rope directly, the rope will come into contact with the end of the thick cap when turning, and smooth rotation will not be obtained. For this purpose, a cap with a small diameter is fitted, a hole is made in this sub cap, and the rope is passed. In order to suppress friction and wear between the hole of the sub cap and the rope, a metal eyelet was attached to the hole of the sub cap. The rope was passed through the sub cap hole, and after the washer was loaded, it was fixed so that the rope would not fall out. A plastic rope having a density higher than that of the cloth rope is used, but by making the diameter 7-8φ thick, the centrifugal force of the rope is increased and the turning performance is improved. A metal wire rope is also used in place of this plastic rope, but since the metal wire is included, the density is increased, and good turning performance can be obtained even with a thickness of around 6φ. As a method for preventing the rope from falling off the cap, the clasp method, or the melt bonding method and adhesive bonding method using the characteristics of plastic materials can be adopted, but the melting bonding method is a heating device, and the adhesive bonding method is an adhesive. Is required. There are various methods for the clasp method, but it is simple and requires a device for completely fixing the rope to the metal fitting. A metal fitting that integrates a pipe and a plate having a hole perpendicular to the pipe direction is used as a stopper for the rope. After passing the rope through the pipe of the clamp, the rope is attached by inserting the tip of the rope into a hole drilled at a right angle to the pipe. This fixing method is simple and is completely fixed by the elastic force of the rope and the frictional force with the metal fittings.

The form of this invention is demonstrated based on drawing. FIG. 1 is an overall view, and FIG. 2 is a cross-sectional view of a grip and a rope-attaching cross-sectional view using a stopper. In the figure, 1 is a grip, 2 is a grip cap to which a rope is attached, 2 'is a grip cap to which no rope is attached, 3 is a rope, 4 is a sub-cap, 5 is a reinforcing pipe, 6 is a metal eyelet, 7 is a washer, 8 is The stopper metal 9 is a balance weight.

The grip cap 2 and the sub cap 4 are fixed with an adhesive, but the grip cap 2 is bonded to the outer peripheral surface of the reinforcing pipe 5 bonded to the sub cap 4 and the end surface of the sub cap 4 in order to complete the bonding. The After the grip cap 2 and the sub cap 4 are bonded, the grip and the cap 2 are bonded. In this jump rope, each part is adhered, but it is necessary to ensure strong adhesion that can withstand repeated vibration and impact, but as a material to respond to this, PVC material and adhesive are excellent materials, If the cap, reinforced pipe, grip, and balance weight are all made of PVC material, the above requirements are easily met. The adhesive used was an adhesive for vinyl chloride, and strong adhesive strength was confirmed. In order to prevent the rope 3 through the hole of the subcap 4 from falling off the subcap 4, it is necessary to enlarge the tip of the rope 3 so that it is caught by the washer 7. For ropes with a diameter of 5φ or less, it is possible to prevent the rope from falling off by making a knot, but this method cannot be adopted if the rope becomes thick. Further, since the rope 3 has a rubber property in addition to the thickness, an attachment method in consideration of this rubber elasticity is required. Therefore, a compact fastener 8 in which a pipe and a plate with a hole are integrated is used. First, after passing the rope 3 through the pipe, the tip of the rope 3 is bent and fixed by being inserted into a hole in the plate. Since this fixing method can be detached by a non-destructive mounting method, the length of the rope can be adjusted. It is possible to fix the pipe by caulking, but the rope length cannot be arbitrarily changed, and the fastening method is an excellent fixing method than the caulking fixing method. In the case of the plastic rope 3, a method of preventing it from coming off with an adhesive can be employed, but not in the case of a metal wire rope. As a mechanical caulking method, there is a method using a wire clip. However, since this clip is relatively heavy and an irritating contact sound is likely to occur during use of a jump rope, the fastener is a useful fixing method.

Effect of device

The present invention uses a plastic tube (cylindrical tube) as a grip to produce a thick grip jump rope that is relatively light and mechanically strong. When the grip becomes thicker, the movement of the wrist is restricted, so the rotational speed of the rope becomes slower than the skipping of the thin grip, and the muscles of the entire body are used to maintain smooth rotation. For these reasons, the use of a thick grip jump rope is beneficial not only for strengthening grip strength but also for strengthening muscle strength of the back muscles, neck, calf, abdominal muscles and the like. Since it is a skipping rope for athletes, the rope must be wearable and durable, hardly twisted, and good in turning ability is also important. From this request, a plastic rope with good wear resistance is used, but the thickness of the rope is also an important factor from the viewpoint of securing the centrifugal force, and a rope with a thickness of 7-8φ is used. Since the rope is thick, it is best to attach the rope with the proposed fastener to prevent it from falling off the grip cap. New adhesion methods and caulking methods such as plastic-specific melt bonding and adhesive bonding can also be used. Inserting washers and eyelets has the effect of reducing friction and wear between the sub cap and the rope, and obtaining good turning performance.

A plastic tube with a thickness of 48φ and a length of 15cm is used as a grip, and a 9.5φ drilled sub cap is bonded to the grip cap with a 25φ x 20 reinforced pipe interposed, and this grip cap is bonded to the grip. Also, a grip cap with a 40 g balance weight (25φx38) bonded thereto was fitted into the grip to produce a jump rope grip. A plastic rope with a thickness of 7φ and a length of 280cm is passed through the processing hole of the sub cap, passed through the pipe of the fastener through a washer, the tip of the rope is inserted into the hole of the fastener, and the rope is attached to create a jump rope. did. Rope jumping was performed in this state, but the thickness of the rope was sufficient, the turning ability was good and the jumping rope function was shown. It was confirmed that the rope was firmly attached. In the absence of eyelets, surface flaws were observed on the surface of the rope in contact with the cap hole, but in the presence of eyelets, surface flaws were not observed, confirming the effectiveness of the eyelets. The weight of one grip of the produced thick grip jump rope was 160 g, and the total weight was 450 g. When using a commercially available thin-jump rope skipper, there is almost no fatigue on the arms and back muscles, but when using a thick-flip rope jumper that has been prepared, the forearm muscles immediately feel a heavy load, and the back, neck, calf Besides, I felt a load on the ankle. This proves that the effect of increasing the grip is greater than the effect of increasing the weight compared to a commercially available jump rope, and is effective not only in strengthening arm strength but also in strengthening muscle strength of the entire trunk. Also, when turning the rope, it is very beneficial to strengthen the muscle strength to fix the wrist, because it is easier to maintain the rotation of the rope by fixing the wrist and rotating with muscle strength including the spine. Also turned out.
