Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement of a ball catching tool for baseball and softball (hereinafter simply abbreviated as ball catching tool).

(Prior art) Conventionally, ball catching tools have been made by forming the catching surface skin from natural cowhide, etc., forming the main body from cowhide or synthetic leather, etc.
A core body 9 made of felt or the like as shown in FIG. 1 was incorporated in a desired part. The purpose of the core body 9 is to provide a desired curved shape to the core body, to adjust the shape of the ball-catching tool, and to make it possible to catch the ball reliably. However, since the core body 9 is generally made using flat plate-like felt, each phase is often in an upright shape, and it has been desired to solve this problem. In addition, since the felt core is made by sewing, it requires the skill of the operator, and the thread used to sew the felt may break or unravel during long-term use. For this reason, various koans such as the following have been made.

In Japanese Utility Model Publication No. 37-16419, a method was devised to create a sponge thumb core that can be curved at a desired angle at the base by attaching and tensioning a slightly short sponge thin plate to the upper surface of the core. ing.

Moreover, in Japanese Utility Model Publication No. 51-24352, [In the core material, the inner core material is provided with a wedge-shaped cut portion at a required portion of its outer edge, and the cut portion of the cut portion is brought into contact with and curved inwardly, and the outer core material is It is easier to catch a ball by providing a required number of oval holes and laminating the inner core material and the outer core material to form an inwardly curved shape than an upright shape, and the outer shape is also regular and does not lose its shape. ” has been disclosed.

In addition, in Japanese Patent Publication No. 51-34778, [a ball-catching surface skin which is set inwardly in the curved shape of the finger and palm of the hand by heating and pressing is cut at the required part to form a core body which is easily bent. This makes it easier to bend the fingers and palms of the hand and follow the natural grasping motion when catching a ball.''

Furthermore, Japanese Utility Model Publication No. 55-5165 discloses that ``A required number of interlining materials are polymerized and sewn together in a state where they are curved to one side of the interlining material, thereby eliminating the restorability of the curvature. In this regard, it has been devised to provide a curved line in the width direction of the core material at a predetermined position of the core material to facilitate ball catching.

Next, in Japanese Utility Model Publication No. 55-5166, the required number of interlining materials are overlapped, and the interlining material is curved to one side of the interlining material and sewn together to eliminate the restorability of the curvature. In this case, reinforcing material such as leather or canvas is layered on the part of the core material that bends when catching a ball and is sewn together to obtain a curve that is easy to reinforce. "Eliminate the shape" was devised.

Moreover, in Japanese Utility Model Publication No. 55-5167, [by applying a core material such as felt or urethane foam to the inside of a core body approximately the size of a thumb pouch formed into a spoon shape from a semi-hard material to form a thumb-shaped core. The patent discloses a device that applies an outward bending force to make it easier for the thumb sack to quickly move in the direction of catching the ball due to the reaction of the ball pressure when catching the ball.

Furthermore, in Japanese Utility Model Publication No. 60-34314, [with a permeable core material curved toward the ball-catching surface side, the front side of the core material is impregnated with a synthetic resin so that the front side and the surface layer area of the core material are impregnated with a synthetic resin. A synthetic resin layer is formed, and a foamed synthetic resin layer is formed on the surface of the core material on the ball-catching surface side to improve shock absorption and shape retention, and prevent back bending of the finger bags due to ball-catching pressure. ``It increases safety and does not lose its shape'', and each is publicly known.

(Problems to be Solved by the Invention) However, the core bodies of these conventionally known ball catching tools have the following problems.

That is, in the method of attaching a short thin sponge plate to the upper surface of the core, the position of the sponge will not be constant and the angle of the core will vary depending on how each person applies the sponge.

In addition, the sponge has a high repulsion property, and when it receives a ball, the ball rebounds, so it has the disadvantage that it tends to fly out of the ball catching tool and cause mistakes in catching the ball.

In addition, in the method of providing a wedge-shaped notch in the core material and aligning the parts to curve inward, the way in which the notches are aligned differs depending on the size of each person's hands, so the curved shape of the ball catching tool itself In addition, the area with the wedge-shaped notch becomes too soft, making it difficult to bend when catching the ball, making it more likely to cause fingering.

In addition, in the method of inserting a core body with the required parts cut into the ball-catching skin set in a curved shape, the cut part becomes soft like the ball-catching tool described above, so when the ball is caught, the outer side of the ball becomes soft. This made it difficult to bend, and there was a risk of stubbed fingers.

In addition, since the core is not curved, when the ball-catching surface becomes soft after long-term use, the core itself returns to its upright shape, reducing its shape retention.

In addition, the interlining is sewn in a state where the interlining is curved to one side, which requires the skill of the person sewing it, and the degree of curvature changes depending on the person sewing it, which is a problem. There was.

Also, if you just want to use a core material such as felt or urethane foam for the core material, which is approximately the size of a thumb pouch and is formed into a spoon shape from a semi-hard material, the leather or the like will become soft after using the ball catching tool for a long time. If the bag got larger, the thumb bag and core material would become misaligned, resulting in poor feel during use and leading to mistakes in catching the ball.

Furthermore, if the core body is to be sewn, it is necessary to curve the core body during sewing, which requires a high degree of skill.

In addition, as shown in Figure 22, when foamed synthetic resin is used for the core, the foamed synthetic resin has a high repulsion property, so when catching a ball, the hole rebounds and there is a drawback that it is easy to miss a ball. there were.

Furthermore, when a ball catching tool is used for a long time, the leather becomes soft and the ball becomes easier to catch. For example, if the core is made of felt, the felt will also deform to a shape that fits in your hand, but with a core made of foamed synthetic resin, there will be less bending, and it will not deform like leather. As a result, there is the problem that it does not stick to your hands over time, and since foamed synthetic resin does not absorb sludge, if your hands sweat a lot in the summer, the sweat will pass through the core and leak out. The problem was that sweat would accumulate in the inner bag, creating a bad odor and mold.

Therefore, it has been desired to provide a core body for a ball catching tool that can be easily formed into a shape, has good workability, has a large cushioning effect, and has good air permeability.

(Means for Solving the Problems) In view of these conventional drawbacks, the present invention provides a ball catching tool having a core body that is rich in moldability and workability, has a large cushioning effect, and has good air permeability and shape retention. It was made for the purpose of providing.

That is, in a ball catching tool composed of an outer skin, an inner skin, and a core,
The core is a core material composed of natural fibers or synthetic fibers and meltable synthetic fibers, and a part of the meltable synthetic fibers of the core material, for example, the peripheral part or the entirety, can be melted. This is a ball-catching tool characterized by forming a three-dimensional core body and incorporating the core body.

Further, in the core of the ball catching tool according to the present invention, a separately formed reinforcing material can be interposed inside or outside the core.

Further, in the core of the ball catching tool according to the present invention, a cushioning material can be interposed inside or outside the core.

Next, in the core of the ball catching tool according to the present invention, it is also possible to form a recess corresponding to the shape of a finger in the portion of the core that the finger comes into contact with.

Further, in the core of the ball-catching tool according to the present invention, a reinforcing portion can be formed by impregnating and curing a synthetic resin in a part or the entire core.

Natural fibers such as wool, cotton, linen, and silk can be used as materials for the core material of the ball-catching tool according to the present invention, and synthetic fibers include nylon, polyester, vinylon, and others. Further, meltable synthetic fibers include polyethylene, polypropylene, ionomer, and others.

Further, as the form of the core material, it is also possible to use a thick non-woven fabric using the above-mentioned fibers or the like, or to use a stack of non-woven fabrics.

Further, it is also possible to use a felt-like raised core material or to use woven materials laminated together.

Further, the shape of the core can be formed to approximately match the shape of each finger portion of the ball catching tool.

The reinforcing material separately formed inside or outside the core may be made of synthetic resin, metal, fiber-reinforced plastic, wood, or any other material that has strength and rigidity, but is preferably made of synthetic resin that can be formed into various shapes. It is desirable to form the

Further, as the buffer member interposed inside or outside the core, polyurethane elastomer, vibration absorbing rubber, etc. can be used.

Other synthetic resins that can be used to form reinforcing parts by impregnating and curing part or all of the core with a synthetic resin include polyester, epoxy, polyurethane, etc., which have good impregnability and relatively curing conditions. It is desirable to use a synthetic resin that is easy to set.

(Function) Since the ball catching tool of the present invention has the above-described configuration, it produces the following functions.

That is, in the core of the ball catching tool of the present invention, among the members forming the core, the meltable synthetic fiber portion melts and fuses, so that, for example, the core made of thick nonwoven fabric By melting only the periphery to form a fused part, it is possible to form a three-dimensional core with a thick center and thinner periphery, thus supplying a large amount of uniform product. It is something that can be done.

This is because with conventional felt cores, felts are laminated and pasted, cuts are formed to provide flexibility, and the felt core is curved during sewing operations. Although the skill level of the upper workers is required, the core body of the ball catching tool of the present invention can be mass-produced in a curved shape very easily.

Furthermore, since the core of the ball-catching tool of the present invention can have a rounded shape with a gentle curve or a cross-sectional shape, when it is built into a ball-catching tool, it is different from the conventional angular one made of felt. The difference is that the feeling is better.

In addition, in the core of the ball catching tool of the present invention, if a fused portion is formed on the peripheral edge of the nonwoven fabric constituting the core material, the core will have a three-dimensional shape. The hardness and flexibility of the core can be varied by widening or narrowing the width, selecting fused and non-fused parts, and changing the thickness of the laminated nonwoven fabric. Because it can be easily done, there is no need to laminate and sew multiple layers of felt to increase thickness, or to increase the number of stitches to increase flexibility, unlike conventional felt. In addition, conventional felt had drawbacks such as the threads at the seams breaking or coming undone from the ends of the felt after long-term use, but the core of the ball catching tool of the present invention Since the body forms a fused part, there is no such risk even if it is used for a long time.

Furthermore, conventional foamed synthetic resin cores have high resilience,
Moreover, even if used for a long time, it has a shape that makes it easy to catch the ball, so it does not get smeared easily, leading to mistakes in catching the ball.Furthermore, it does not have sweat absorption properties, so sweat and moisture can cause bad odors and mold. However, in the core of the ball catching tool of the present invention, for example, if needle felt made of wool, polyester, or polyethylene and subjected to needle punch processing is used as the core material, the repulsion property is low and it is not possible to use it. While holding the ball, it easily deforms to conform to the shape of the outer and inner skin of the ball catching tool, which prevents mistakes in catching the ball.It also has good breathability and water absorption, so even if you use the ball catching tool for a long time, you will not sweat. There is no accumulation of water or water droplets.
It is comfortable to use, and unlike conventional foamed synthetic resin cores, it does not produce bad odors or mold from sweat or moisture.

Furthermore, in the core of the ball catching tool of the present invention, a reinforcing material is interposed inside or outside the core. For example, the reinforcing material is placed inside the core and the core is fused. Since it is also possible to form a similar amount of curvature and roundness, it is possible to supply a core body having a shape that conforms to the shape of the ball catching tool. In addition, by inserting a reinforcing material inside the core, the impact when catching a ball is alleviated, and at the same time, since the core is interposed between the reinforcing material and the hand, it becomes a ball catching tool with an extremely soft feel. Since the reinforcing material can be bent slightly toward the ball-catching surface together with the core material, it will not warp in the opposite direction even in response to impact stress at the time of catching a ball, so it is possible to prevent finger pointing.

Furthermore, if the reinforcing material is placed outside the core material, it is possible to prevent the ball from warping even if a ball is caught at a higher speed.

In addition, in the core of the ball catching tool of the present invention, by arranging a cushioning material with low repulsion inside or outside of the part of the core that corresponds to the finger contact, the impact when catching the ball is reduced. In addition, by placing a cushioning material on the outside of the core on the ball-catching surface side, the repulsion to the ball is suppressed during ball catching, making it easier to catch the ball.

Furthermore, if a cushioning material is placed inside the core at the part that comes into contact with the hand, the impact can be alleviated even when catching a fast-moving ball, thereby preventing injury to the hands and fingers.

In addition, in the core body of the ball catching tool of the present invention, by forming a concave portion approximately in the shape of a finger on the surface of the core body at the portion where the finger comes into contact, the retention of the finger within the ball catching tool is improved. It is something.

In addition, in the core of the ball catching tool of the present invention, a part or the entire core can be impregnated with a synthetic resin and hardened, but in particular, it is possible to impregnate and harden the synthetic resin only in the widthwise central part of the core. By impregnating and curing it, a stiffener and rib structure can be formed, and it will not warp in response to impact stress when catching a ball, and can prevent fingers from hitting the ball.

In addition, by impregnating and curing the entire ball-receiving surface side of the core with foamed polyurethane or a synthetic resin that is soft even when cured, the hand side retains the soft feel of the core itself, while the ball-receiving surface side retains the soft feel of the core itself. The core body has a structure with lower repulsion than the ball catching tool, and it is possible to provide a ball catching tool with good flexibility and no ball catching mistakes.

(Example) Next, an example of the ball catching tool according to the present invention will be described based on the drawings.

That is, as shown in FIGS. 1 to 4, the outer skin 2 and the inner skin 3
In the ball catching tool 1 composed of a core body 4, the core body 4 is a core material 4a composed of natural fibers or synthetic fibers and meltable synthetic fibers, and includes a part of the meltable synthetic fibers. The whole is melted and a fused part 4b is provided to form a three-dimensional core body 4,
This is a ball catching tool characterized by incorporating the core body.

Further, as shown in FIGS. 5 and 6, in the core 4 of the ball catching tool of the present invention, a reinforcing material 5 can be interposed inside or outside the core 4.

Further, as shown in FIGS. 7 to 11, in the core body 4 of the ball catching tool of the present invention, a cushioning material 6 is provided inside or outside the core body 4.
It is also possible to intervene.

Furthermore, as shown in FIGS. 12 to 15, in the core body 4 of the ball catching tool of the present invention, a finger-shaped recess 7 can be formed in the finger-contacting part of the core body 4. be.

In addition, as shown in FIGS. 16 to 20, in the core body 4 of the ball catching tool of the present invention, a reinforced portion is formed by impregnating and hardening a part or the entire core body 4 with a synthetic resin. 8 can be formed.

In addition, as for the form of the core body of the ball catching tool of the present invention, ball catching tool 1
A shape that approximately matches the part corresponding to the finger portion 1a of the
It is possible to have a continuous curved shape from the thumb 1b through the lower part of the palm to the little finger 1c, or a shape that is divided in the middle.

Further, as the material for the core material 4a forming the core body 4 of the ball catching tool 1 of the present invention, natural fibers such as cotton, wool, linen, silk, etc. are used, and synthetic fibers such as nylon, polyester, vinylon, etc. are used. They can be used alone or in combination as appropriate.

Further, as the meltable synthetic fiber, polyethylene, polypropylene, ionomer, and other materials can be used.

(Effect of the invention) As described above, in the core of the ball catching tool according to the present invention,
A core material is formed with natural fibers or synthetic fibers with meltable synthetic fibers interposed between them, and the meltable synthetic fibers are melted and fused where necessary using heat-pressure pressing or welding processing. By doing so, it is possible to form various three-dimensional shaped cores extremely easily, and the width of the fused portion and the thickness of the core material constituting the core can be made thicker or thinner as appropriate. Accordingly, a core having good flexibility and bendability can be easily obtained.

For these reasons, unlike the production of conventional felt cores, no operator skill is required, and cores of various shapes can be mass-produced. Furthermore, unlike conventional sewn felt cores, the threads do not break or unravel even after long-term use, resulting in good durability of the core.

Furthermore, the core of the ball-catching tool of the present invention adapts to the shape of the ball-catching tool while being used, making it easier to catch balls, so it will last forever in your hand, unlike the conventional foamed synthetic resin core. There is no need to worry about getting used to it, and the feeling of the ball catching device is better, and since the repulsion of the ball does not become high, it is possible to prevent the ball from being bounced off when catching the ball, which can lead to mistakes in catching the ball. It's also effective.

In addition, the core of the ball-catching tool of the present invention has good breathability, so even if the ball-catching tool is used for a long time, sweat and moisture from perspiration will be absorbed by the core of the conventional foamed synthetic resin core. Unlike the body, water does not accumulate as water droplets, so it does not cause bad odors or
It can also prevent mold from forming.

In addition, in the core of the ball catching tool of the present invention, a reinforcing material can be inserted inside or outside the core, so it feels soft in use and reduces the impact when catching a ball. In order to prevent reverse warping, etc., it has the effect of preventing poked fingers and other injuries to the fingers.

In addition, in the core of the ball catching tool of the present invention, if a cushioning material is placed inside or outside the core, the impact when catching a ball is alleviated and the repulsion is also suppressed. It is possible to prevent mistakes in catching the ball without having to push the pole too far.

In addition, in the core of the ball catching tool of the present invention, by forming a finger-shaped recess in the finger contact portion of the core, the sense of unity between the finger and the core is increased, and it is possible to catch a ball with high speed. Even when playing a ball, the force of the fingers is quickly transmitted to the core body, making it possible to quickly close the ball-catching device inward, thereby preventing mistakes in catching the ball. In addition, it was difficult to form finger-shaped recesses with conventional felt cores because it was very time-consuming and the sewn parts might come undone during use, but the present invention By fusing the core of the ball catching tool,
Since finger-shaped recesses can be freely formed, mass production is possible, and there is no fear of unraveling during use, resulting in a durable core.

Furthermore, in the core of the ball-catching tool of the present invention, by impregnating and curing appropriate parts of the core material constituting the core with synthetic resin, these parts are reinforced and act as stiffeners and ribs. Because of this, the ball does not warp in the opposite direction due to the impact when catching the ball, so it is possible to prevent the ball from hitting the ball.
