Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to an improvement in a hi-ray sester. This is a hand-held device for throwing and catching small hard balls that can bounce off a three-wall coat.

[Conventional technology and problems]

Hiarai is a super-high-speed variant of a three-wall handball, and the player uses a curved wicker basket with a length of two feet called a Sester. Tie a ball with a very hard momentum that can bounce off the wall, and at almost the same time throw it on the wall in front and let the opponent player catch it and throw it back, so it's tied to the player's hand with a strap. Used sester.

The traditional traditional Hi Arai Sesta is an expensive custom made according to the specifications of each player,
Handcrafted with imported reed strips and wood materials. These sesters have a hand grab part, in which the player's right hand is inserted into this hand grab, the wrists are tied together with a strap for the operation and control of this sester, and the user's right glove is in use while the hand grab is in use. Do not fall out of your arm. Due to the unique shape of the traditional Sester and the position of the hands tied flat with a strap on the surface of the grab at the rear end of the Sesta, the player has a good chance of catching and throwing a hard ball well. It requires very simultaneous arm swings and body movements. Tennis, racket ball, squash, etc.
When a player skilled in other sports using a racket does Hirai for the first time, it feels very difficult to get used to this game, and it is not easy to acquire the technique for controlling and mastering the traditional sesta. Moreover, these people are much more difficult to master the technique of imparting spin to the ball. Spin is one of the new shots in this game. This is because the ridge of the ball runway along the inner surface of the conventional sester is very shallow due to the thin structure of thin reed strips woven into the wood ribs. The height of these ridges is less than 1/64 inch. Considering that the diameter of the hard ball is about 2 inches, this is just insufficient mechanical means to add spin during a beginner's swing. Experienced practitioners have added that by adding a wrist snap to the shot,
A desired spin can be given. But beginners need a lot of time and heavy training to add spin. Also, if the catch fails, the player is at risk of receiving a hard ball flying at a speed of about 150 mph. This is the
This is because the maximum distance from the player's body to the ball receiving portion (scop portion) is only the length of the arm. Consequently, players who are starting to get used to having their correct position in the court, due to such a very small safety margin, will be particularly injured.

The glove method in which the wrist of the player is tied with a strap in comparison with the conventional sester has the following drawbacks.

a) This game has a very fast pace, points are scored in a few seconds and, as a general rule, players alternate from game to game during the competition, so players need to quickly rest their sweaty hands and let them breeze. Yes, and the grab format is very inconvenient. It takes a considerable amount of time to remove and reattach the device.

b) The standard type cester has limited compatibility between right-handed and left-handed players, and is not easily adjusted to accommodate different sizes of hands.

c) Since the position of the hand in the grab part of the standard type Sester is fixed, the variations of the shutter and the catch that the player can use are limited.

d) The strap, tightly wrapped around the player's wrist, exerts a great deal of pressure on the wrist during use of the Sester, impeding blood circulation in the player's arm, causing hand pressure pain,
This produces cramps and paralysis.

e) Due to the lack of ventilation inside the grab, the sweating of the hands is severe.

U.S. Pat. No. 642,628 is an old type of traditional sester that is currently used by Hierai professional players. The inner side surface of this sester is formed by crossing several vertical members constituting the main body and knitting a strip of wickerwork on the side bar. This knitted strip is overlaid on the warp to create a shallow ridge inside the scoop. The natural tendency of "deflecting" when impacted by a catching ball is that the vertical members are struck when impacted by a basketball ball, where several separate vertical members are held together by a wicker strip. By giving space to bend. The manufacturing process of this structure is very laborious, complicated and expensive.

Other similar sesters are disclosed in U.S. Pat. Nos. 4,098,508 and 4,273,339 except that plastic materials are used in place of conventional reed strips and wood materials. The major difference between the structures of these two patents is that the former fixed the lining of elastic material in the ball receiving scoop part in order to absorb the impact of the ball and to properly catch the ball and prevent it from jumping out of the sester. It is in.
The manufacture of a sester of this construction requires several materials, which makes it a complicated, expensive and bulky and heavy sester. The hand-securing means also comprises a finger hole in the grip, in which structure a strap of flexible material forms a loop to secure each finger of the player's hand to the grab portion of the sester. It is organized as follows. This facilitates adapting to different sizes of player's hands. The problem with this structure is that it is very complex, requires a large number of finger holes and slots in the sester itself, requires different materials, and is very expensive to manufacture.

On the other hand, the sester of US Pat. No. 4,273,339 consists of an integral part of polystyrene and has outwardly facing flange portions at both ends of its ball-bearing scoping part, which is a slidable U-shaped plastic strip strip reinforcement. Covered by material, this reinforcement serves as a post. The grab member also includes two rectangular cloth layers sewn together to form a finger hole. In this sester,
It is extremely difficult to control the ball path when the ball is thrown and when the catch is performed. This is because its inner surface is smooth and has no ability to give spin to a hard ball. In addition, this structure provides sufficient shock absorption when the ball is scratched, and therefore has poor ball retention properties. Another Sesta is the "Sesta Ball" sold by Brownwick, which is similar to the device disclosed in US Pat. No. 4,273,339.
The dimensions are smaller than this. All of these sesasters have all the drawbacks of the prior sessers mentioned above, because they require a wrist strap to secure the sessa to the player's arm, presenting a great problem to Hi Alai lovers.

A modification of the device with the handle used to throw and catch throwables is described, for example, in U.S. Pat.
No. 186, No. 1,530,573, No. 2570,958, No. 2,710,753
Nos. 3,170,688 and 4,045,026.

There are also some toys that mimic the Hiarai Basketball and Lacrosse Stick. One of such toys is made of molded polyethylene plastic, which has a flat, miniature flat continuous surface bent in an arc shape at the front, and a short cylindrical hollow handle is attached to its lower end. A funnel pocket is provided at the end of the arcuate portion adjacent to the upper end of the handle, the main function of which is to hold and carry the ball taken at the other end for a certain period of time. The other end is open as a starting pad for the light ball used.

Another brand of "high-light" omochi has a Hirai basket, but does not have the long J-shaped tip of the conventional Sesto. This tongue is constructed by knitting a wide knitted material in a very narrow spoon shape. A rectangular member made of the same type of braided material, without the use of grabs to secure it to the hand, the end of which is fixed to the side bar of the basket to cover the surface of the grab part. It forms an arch or bridge.

This is inserted in this arch with your palm facing down,
It is to prevent slipping during use. But,
Insert into the arch because the size of the arches or groove holes in this arch is too loose to adjust and many sharp ends of the knitted braid material project from the seam to the surface. It is easy to hurt your bare hand.

Another of these toys is that the basket is made by bending several rattan ribs to form a spoon-shaped scoop with a short cylindrical handle. However, like the Lacrosse Stick, all of these devices are used for catching and throwing back rubber or very soft plastic balls directly between players with an open field. It is not suitable for playing on such a 3-wall court.

[Objects and effects of the invention]

What is needed to overcome each of the problems and drawbacks described above is a flexible hand with a whip, or finger hole, along the handle without the use of custom grabs and unpleasant wrist straps. It is a high alicestor that can be mass-molded from a quasi-flexible material or plastic with fixing means and an integrally molded catch surface having a high impact absorbing capacity. If a device with these features is manufactured, anyone interested in Hialai can use it in a normal walled court and with a minimum of effort and training in a short time. , A simple, safe, efficient, durable, convenient, and readily available Hi-Arii device that will allow you to learn the swing basics required for various shots using hard balls. This would standardize the sester without the need for a custom sester and would be a universal fit suitable for any player. This would also put the player on the same playing field in terms of equipment, making Hiarai a strict technical contest for the player.
The sester of the present invention provides such a device.

[Outline of Invention]

According to the illustrated embodiment, the present invention provides a ball catch / throw device or a modification thereof that can be used for hierai and similar games. The device includes a handle secured to the scoop for catching and ejecting the ball. This scoop part has a large "C" shape and has a pair of parabola side bars alternately connected by curved slopes, which is a shallow arc at the end of the scoop opposite the handle. Forming a raised edge portion. The other end of the side bar of the scoop part forms a forked extension of the handle part.

In other words, the device comprises a handle fixed to the scoop, the scoop comprising a basket with a narrow slender slope, the slope starting at the shank and forming a sharply curved bottom. The bottom is the deepest point. From this deepest point, the radius of the arc of inclination gradually increases to form a slightly arcuate upper part, the inclined surface of which is substantially perpendicular to the longitudinal axis of the handle.

Whips are attached to both ends of the handle to help the user grip the handle of the device. The whip consists of two straps, one strap with a permanent rope at one end and the other strap knitted through slits on either side of the rope to form adjustable sized finger holes.

The inside of the scoop is made of a single piece of elastic material shaped to have a series of accordion-like depressions that run along this surface to absorb the impact of the catched ball and impart spin to the ball being thrown. Composed of parts.

〔Example〕

Figures 1 to 4 show a tester injection molded from a high impact resistance and semi-flexible material such as plastic. This sester features a long handle 22 in place of the standard flat grab portion of a conventional sester. Also shown are the ball receiving scoop portion 8 and the whip 25, a flexible hand securing means for use with the handle. One end of the whip 25 is fixed or riveted to the upper end 20 of the handle 22, and a finger hole 23 is formed near the lower end of the handle for the convenience of fixing the hand and grip. A cross-sectional view of the deepest part of the ball receiving scoop portion 8 along line 5-5 is shown in FIG. 5, which comprises side portions 10 and 14 interconnected by an inner curved portion 12. It has a contour close to a parabola, and the inner curved portion 12 has its tip portion.
As it approaches 13, it has transformed into a very slightly curved surface. Also shown in FIG. 5 is a cross-section of the thick sidebars 16 and 18 of the ball receiving scoop portion 8 which surround the entire scoop portion and are connected to the handle 22. Cross-sections and perspective views of the inner side surface of the ball receiving scoop portion 8 are shown in FIGS. 5 to 8, and the inner side surface is formed by several rows of fine concave shapes juxtaposed from the base portion 21 to the tip portion 13. It consists of an oval shaped depression. These depressions consist of a series of semi-circular arcuate portions 10b and raised ridges 10a projecting along the inner surface of the scoop portion as shown in FIG. Optionally, vents or slots may be provided in the center or sides of these rows of depressions forming the main ramp to reduce air resistance to movement of the scoop 8.

The ball receiving scoop portion 8 forms a narrow elongated shout extending from the uppermost end portion of the handle portion 22 and reaches a deep cross-section portion 5-5 from a very steep base portion, and from there, a slightly arcuate tip portion. Up to 13, the degree of curvature gradually decreases, and the inclined surface of this tip is almost perpendicular to the vertical axis of the handle, forming a crescent-shaped narrow basket as shown in FIG. . The handle 22 is elongated and has an oval cross section and is provided with a rivet or bottle 28 at the end opposite the end to which the scoop portion 8 is attached. One end 26a of the whip 24 is fixed to the pin 28. The other end 24 of the whip 24 is attached to the upper end of the handle 22, that is, the lower end of the ball receiving scoop 8.
A is fixed by a rivet 20 as shown in FIG. The handle 22 has a buttocks 27 to make it easier to handle, and narrows toward the neck, and the back of this neck is the base of the scoop 8 as shown in FIGS. 2 to 4. It follows a sharp curved shape. The edge of the scoop portion 8 branches from the top of the handle portion into a branch of a tuning fork, and in the central portion, it is curved forward by an arc of 98 ° to form the outline of the ball receiving scoop portion 8. Sidebar on the scoop part 16
And 18 serve primarily to surround and reinforce the scoop portion 8 as shown in FIG. Whip 25 is generally leather,
Or made of other flexible, elastic material and including two narrow straps 24 and 26, which are joined to have a length of about 26 inches. Main strap 24
Has a width of about 1/2 inch over about 15 inches of its length and expands to about 1 inch across the remaining 11 inches of its length. The other strap 26 is relatively flexible and narrow,
It is used as a partition for manufacturing the finger hole 23 and has a uniform width over its entire length. The wide portion of the main strap 24 is folded back and its ends are sewn or riveted to itself at point 24b, where the wide portion ends. Narrow strap 26 is the main strap
It is inserted in a rectangular slit provided in 24 loops. The strap 26 is knitted through the slits 24c, 24d, 24e from one end thereof fixed at 24b, and then returned to the slit 24c to move to the next slit 24c.
It is knitted into f, 24g, and 24h, and returns to slit 24f again.
This is illustrated in Figure 9. Alternatively, the straps 26 are sewn alternately between the inner surfaces of the loop portion of the main strap 24 to form four comfortable finger holes 23 adapted to the player's hand. The narrow end of the main strap 24 is provided with a hole 24a for riveting to the anchoring point 20 on the inner base of the ball receiving scoop 8 or to the top of the handle 22 or any other point. The free end of the narrow Divide dust lip 26 is provided with several central holes 26a for detaining the rivets or pins 28 provided on the underside of the base 27 of the handle 22 to allow the handle to be free around the hand. Can be adjusted to rotate. By providing the plurality of holes 26a, the size of the finger hole 23 and the length of the whip 25 can be adjusted.

The long handle 22 is primarily intended to facilitate gripping, increasing player reach and safety, allowing the Cester's swing direction to be adjusted, allowing more dimensional and shots for the game. Give sex,
It provides a stable base for the ball-bearing scoop 8 and its sidebars 16 and 18 and serves as a strut and reinforcement for the sester. Also, the longer handle allows the ball (rotational body) to be placed farther from the pivot point of the player's shoulder, and thus more when the ball is thrown by the player's swing. It is also important to give the ball inertia to the ball. Pins 28 and holes 29 in handle 22 serve as fixation points for whip 25, which secures the player's hand to the sester. Whip 25 strap 24
Serves as the primary member that undertakes the tension created in the whip during the player's ball-throwing swing. The other strap 26 is a slit on the looped end of strap 24.
Being knitted into 24c-24r to form finger holes as shown in Figure 9 to act as a comfortable adjustable divider or spacer between the fingers of the player to fit hands of various sizes You can The central hole 26a of the whip serves to adjust the tension or looseness of the whip appropriately and conveniently for the grip of the player along the handle 22.

A cross-sectional view 5-3 showing the deepest part of the ball passage along the inner curved portion 12 of the scoop portion prevents the ball from rolling out from the base portion 21 of the scoop portion 8 after the catch and serves as a starting point of the ball runway. , Ball receiving scoop part 8
It provides a long track for producing a sufficient moment of inertia inside, and, despite the smaller scoop size of a conventional sester, gives sufficient and speed and force before the ball bounces off the wall. This structure also provides extra space for catching balls with difficult and unusual, unexpected trajectories.

The tip portion 13 of the scoop portion 8 serves as a suitable entry and departure pad for guiding the ball before it flies toward the target. Since the tip portion 13 often collides with the floor surface and the wall surface during the game, this tip portion is formed thick in order to prolong the life of the sector of the present invention.

As shown in the enlarged view of FIG. 6, a semicircular recess 10b protruding along the inner surface of the ball receiving scoop 8 and its raised edge 10 are formed.
The row a gives the sester its high impact properties and effective ball retention performance. At the moment the ball is clawed, the raised edge 10a acts as a contact, first absorbing the impact energy from the high speed hard ball, transmitting this energy to the semi-circular recess 10b, and flexing these recesses several times. No expansion (depending on how many times the ball bounces inside the scoop part 8) thus dissipating most of the impact energy and significantly slowing down the ball speed, thus allowing the ball to scoop It prevents the part 8 from protruding.

Also, these deep raised edges 10a provide an effective mechanical means for imparting spin to the ball if desired. The body of the deepest portion 5-5 of the ball receiving scoop portion 8 is formed in a cross section close to a parabola as shown in FIG. This provides a large bounce space after the ball has been scratched, and the narrow entrance limited by the sidebars 16 and 18 combines with the high impact properties of the molding surface to allow the ball to scoop. Helps to keep it from sticking out of the part. As an option, a hole or groove hole is provided at the center or side of one of the concave rows forming the main bending portion of the ball receiving scoop portion 8 to allow air to pass therethrough during the swing of the player, thus It is possible to prevent the formation of an air flow inside the scoop portion 8 that bends the trajectory of the ball and reduces its force and speed, and increases the energy required for the swing of the player.

With such a combination, in particular, the snap tension in the whip 25 and the improvement of the lever action due to the long radius of the ball track along the inner surface of the scoop portion 8 centering on the shoulder of the player are projected. Means are provided to increase the energy to the ball while at the same time reducing the stress used in the swing of the player.

These factors make it easier to swing the player without compromising the speed and accuracy of the player's shot. In addition, the player can grip the handle in various ways along the outer circumference of the handle, and the long handle can be gripped.
22 increases safety margins for players, so
It is possible to make various shots and caches that were not possible with conventional sesters. The handle 22 is designed to be long enough to allow the scoop 8 to be twice as far away from the player's body during the player's catching action, thereby allowing the player to be injured by a high speed, hard ball. Reduce the risk of This also gives a long reach for catching high flying balls.

Also, the long handle 22 makes it easy for many people who already play tennis, a racket ball or other sports with a handle racket to properly handle a hard ball sester and acquire the necessary skills. The combination of a long handle and a whip, or flexible hand-securing means with finger holes, provides a universal fit sester. This Sester is easy to use for children, teenagers, adults, men and women, left-handed and right-handed, without greatly deforming it or using general fittings. To be done.

The inner surface of the scoop portion 8 provides maximum ball retention during the catch operation, and effectively imparts spin to the ball when it is thrown against a wall surface, and the economics of the Sester. It is designed to be capable of mass production.

This surface is molded as a unitary structure of plastic or synthetic material and is shaped into a unique array of depressions that run like an accordion along the surface to absorb the impact of the ball by the "accordion effect". This design gives excellent ball holding performance, and at the same time gives a large amount of spin to the shot. The "accordion effect" means that the surface acts like an accordion and is impacted by the ball. It means that the impact force is dissipated by being stretched instantaneously. This is obtained by molding the surface of the scoop part itself in the form of elongated recess rows. Fig. 5 ~
FIG. 8 shows an embodiment of the aforementioned surface having such characteristics.

These surfaces eliminate extra elastic material to absorb the impact of high speed balls as in other devices. These surfaces also allow the surface thickness to be minimized without compromising strength, thereby reducing material costs and at the same time making it possible to produce the desired lightweight device.

As is apparent from the above description, the present invention provides a novel and advantageous design for a high-alignment sester.
As is apparent to those skilled in the art, the present invention can be arbitrarily modified and implemented within the scope of the gist thereof.
