Description

Technical Field

[0001] The utility model relates to a sports article, in particular to a softball bat. Background Art

[0002] Most of the current softball bats on the market are made of integrally formed wood or metal materials, or the bat body and the handle are made of different materials and then bonded by resin glue. For the above two common bat structures, the bat body and the handle are both rigidly connected. This makes the vibration on the bat body transmit to the player's hand along the handle when the player continuously hits the softball. After hitting the ball for a long time, the player will feel uncomfortable with numbness in the hand when holding the bat, and it is difficult to hold for a long time, resulting in a poor user experience of the bat. Content of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a softball bat with a vibration damping effect.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0005] A softball bat with a vibration damping effect includes a bat body. The bat body includes a bat body in the upper part and a handle fixed to the lower end of the bat body. A vibration damping sleeve is arranged between the bat body and the handle. The upper end of the vibration damping sleeve is fixedly connected to the lower end of the bat body, and the lower end of the vibration damping sleeve is fixedly connected to the upper end of the handle. After being fixed, the height of the lower end face of the bat body is higher than the upper end face of the handle, so that a vibration damping area is formed between the bat body and the handle.

[0006] The lower part of the bat body is a reduced diameter structure with a wider upper part and a narrower lower part, and the upper and lower ends of the bat body are open with an upper opening and a lower opening. The vibration damping sleeve is adhesively fixed in the lower opening; an upper cover is also installed in the upper opening of the bat body, and a stepped surface is recessed at the edge of the upper cover, and the upper end face of the bat body abuts against the stepped surface.

[0007] The vibration damping sleeve is a funnel-shaped structure with both ends open and the width of the upper opening greater than that of the lower opening. The upper end of the handle is adhesively fixed to the inner wall of the lower end of the vibration damping sleeve.

[0008] The height h of the vibration damping area is 2 - 5 cm.

[0009] The bat body is composed of an outer fiberglass layer, an inner fiberglass layer, and an intermediate fiberglass layer located between the outer fiberglass layer and the inner fiberglass layer. A carbon fiber layer is arranged between the outer fiberglass layer, the inner fiberglass layer, and the intermediate fiberglass layer. The carbon fiber layer is fixed to the outer fiberglass layer, the inner fiberglass layer, and the intermediate fiberglass layer by an adhesive method. A release film for reducing the vibration of the bat body is also arranged in the intermediate fiberglass layer.

[0010] The outer fiberglass layer is formed by bonding a layer of fiberglass cloth with an included angle of 60 degrees between warp and weft on the outside and four layers of fiberglass cloth with an included angle of 30 degrees between warp and weft on the inside.

[0011] The inner fiberglass layer is formed by bonding a layer of fiberglass cloth with an included angle of 60 degrees between warp and weft on the outside, a layer of fiberglass cloth with an included angle of 45 degrees between warp and weft in the middle, and a layer of fiberglass cloth with an included angle of 30 degrees between warp and weft on the inside.

[0012] The middle fiberglass layer is formed by bonding three layers of fiberglass cloth with an included angle of 60 degrees between warp and weft on the outside and two layers of fiberglass cloth with an included angle of 30 degrees between warp and weft on the inside. The release film is placed between the three layers of fiberglass cloth with an included angle of 60 degrees between warp and weft on the outside and the two layers of fiberglass cloth with an included angle of 30 degrees between warp and weft on the inside.

[0013] The carbon fiber layer is composed of a single layer of carbon fiber cloth with an included angle of 45 degrees between warp and weft.

[0014] A bottom cover is threadedly connected to the lower end of the handle, and an anti - detachment step extends outward from the lower end of the bottom cover.

[0015] The beneficial effects of the present utility model are as follows: A damping sleeve is provided between the rod body and the handle of the present utility model, and the height of the lower end surface of the rod body is higher than the upper end surface of the handle, so that a damping area is formed between the rod body and the handle. When a player hits a softball for a long time, the vibration generated by the rod body hitting the ball is absorbed by the elastic damping sleeve, preventing the vibration from being transmitted along the handle to the player's hand, reducing the vibration of the handle, and the player will not feel discomfort when holding the handle to hit the ball for a long time, thus improving the use experience of the bat.

[0022] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments may be combined with each other.

[0023] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model.

[0024] Referring to Figures 1 to 5 , a softball bat with a vibration damping effect, including a bat body 1, the bat body 1 includes a bat shaft 11 in the upper part and a grip 12 fixed to the lower end of the bat shaft 11. A vibration damping sleeve 2 is provided between the bat shaft 11 and the grip 12. The vibration damping sleeve 2 is made of a material with a certain elasticity such as nitrile rubber. The upper end of the vibration damping sleeve 2 is fixedly connected to the lower end of the bat shaft 11, and the lower end of the vibration damping sleeve 2 is fixedly connected to the upper end of the grip 12. After fixation, the height of the lower end surface of the bat shaft 11 is higher than the upper end surface of the grip 12, so that a vibration damping area 3 is formed between the bat shaft 11 and the grip 12; in the present utility model, a vibration damping sleeve is provided between the bat shaft and the grip, and the height of the lower end surface of the bat shaft is higher than the upper end surface of the grip, so that a vibration damping area is formed between the bat shaft and the grip, that is, there is no overlapping area on the vertical projection plane between the bat shaft and the grip. The vibration between the bat shaft and the grip is transmitted through the vibration damping sleeve made of an elastic material. The elastic potential energy transmitted by the bat shaft is absorbed and consumed by the vibration damping sleeve, reducing the vibration transmitted to the grip, so that after the player hits the ball, the vibration of the grip is weakened, and the holding feeling of the bat is improved.

[0025] The lower part of the bat shaft 11 is a reduced-diameter structure with a wider upper part and a narrower lower part, and the upper and lower ends of the bat shaft 11 are open with an upper opening and a lower opening. The vibration damping sleeve 2 is adhesively fixed in the lower opening. An upper cover 4 is also installed in the upper opening of the bat shaft 11. A stepped surface 41 is recessed at the edge of the upper cover 4, and the upper end surface of the bat shaft 11 abuts against the stepped surface 41. During assembly, the grip is inserted into the cavity inside the bat shaft through the upper opening and passes out through the lower opening, and the grip is fixed at the lower opening by applying epoxy resin glue on the outer side of the grip.

[0026] The vibration damping sleeve 2 is a funnel-shaped structure with both ends open and the width of the upper opening greater than that of the lower opening. The upper end of the grip 12 is adhesively fixed to the inner wall of the lower end of the vibration damping sleeve 2. The bat shaft and the vibration damping sleeve adopt a reduced-diameter structure with a wider upper part and a narrower lower part. During installation, apply epoxy resin glue on the outer side of the vibration damping sleeve and pull it down forcefully until it is tightly attached to the inner wall of the lower opening of the bat shaft to complete the assembly.

[0027] The height h of the vibration damping area 3 is 2 - 5 cm; as Figure 5As shown, the height h of the shock-absorbing area (i.e., the vertical distance between the lower end of the rod body and the handle) is set to 2-5 cm. By limiting the height of the shock-absorbing area, it is avoided that the overall controllability of the bat decreases due to the overly long shock-absorbing area, and at the same time, it is also avoided that the shock-absorbing effect is poor due to the overly short shock-absorbing area.

[0028] The rod body 11 is composed of an outer glass fiber layer 13, an inner glass fiber layer 14, and an intermediate glass fiber layer 15 located between the outer glass fiber layer 13 and the inner glass fiber layer 14. A carbon fiber layer 16 is provided between the outer glass fiber layer 13, the inner glass fiber layer 14, and the intermediate glass fiber layer 15. The carbon fiber layer 16 is fixed to the outer glass fiber layer 13, the inner glass fiber layer 14, and the intermediate glass fiber layer 15 by bonding. A release film for reducing the vibration of the rod body 1 is also provided in the intermediate glass fiber layer 15. The rod body of this embodiment is made of a laminated structure of glass fiber layers and carbon fiber layers. At the same time, a release film is also sandwiched in the glass fiber layer. Using this rod body structure makes the rod body of the softball bat have stronger toughness. Compared with a glass fiber bat made of a single material or a bat made of materials such as metal or wood, it will not break or be damaged after being struck a relatively large number of times, extending the service life of the bat; the outer glass fiber layer 13 is formed by bonding an outer layer of glass fiber cloth with an included angle of 60 degrees between the warp and weft and an inner layer of four layers of glass fiber cloth with an included angle of 30 degrees between the warp and weft. The inner glass fiber layer 14 is formed by bonding an outer layer of glass fiber cloth with an included angle of 60 degrees between the warp and weft, a middle layer of glass fiber cloth with an included angle of 45 degrees between the warp and weft, and an inner layer of glass fiber cloth with an included angle of 30 degrees between the warp and weft. The intermediate glass fiber layer 15 is formed by bonding three outer layers of glass fiber cloth with an included angle of 60 degrees between the warp and weft and two inner layers of glass fiber cloth with an included angle of 30 degrees between the warp and weft. The release film is placed between the three outer layers of glass fiber cloth with an included angle of 60 degrees between the warp and weft and the two inner layers of glass fiber cloth with an included angle of 30 degrees between the warp and weft. The carbon fiber layer 16 is composed of a single-layer carbon fiber cloth with an included angle of 45 degrees between the warp and weft. When a player hits the ball, the hand often becomes numb and uncomfortable after a long time of hitting due to the vibration of the bat. Usually, the time of the game or training is relatively long, which results in a bad feeling when the player holds the bat. Therefore, in this embodiment, a release film is provided in the intermediate glass fiber layer, which can reduce the vibration of the bat and improve the use feel of the bat when the player hits the softball.

[0029] A bottom cover 17 is threadedly connected to the lower end of the handle 12, and an anti - detachment step 18 is provided at the lower end of the bottom cover 17 and extends outward. The anti - detachment step can prevent the baseball bat from being thrown out when it slips. Through the limitation of the anti - detachment step, when it slips, the anti - detachment step can abut against the player's palm, so that it will not be thrown out farther due to inertia, improving the safety of using the baseball bat.

[0030] The baseball bat of this embodiment can reduce the vibration of the baseball bat through the damping sleeve, and by using a rod body structure with a glass fiber layer and a carbon fiber layer laminated and a release film provided in the glass fiber layer, thereby improving the feel of the baseball bat, enabling the player to exert 100% of the swing speed. This utility model has also obtained the professional certification of the United States Specialty Sports Association (USSSA).
