A softwood table tennis bat

Abstract

This utility model relates to a cork ping-pong paddle, belonging to the field of sports equipment technology. It includes a solid wood layer and cork layers adhered to both sides of the solid wood layer. The cork layers are fixedly connected to the solid wood layer via an adhesive layer or by insertion. The adhesive layer is double-sided tape. The thickness of the solid wood layer is 5-8mm, and the thickness of the cork layer is 2-3mm. The cork layer 300 replaces the sponge layer. Compared to the sponge layer, the cork layer 300 is more durable and robust. Furthermore, the cork layer 300 is connected to the solid wood layer 100 via double-sided tape, which offers better elasticity than traditional glue-based connections. This is because glue forms a plastic layer after solidification, lacking elasticity, while double-sided tape provides a certain degree of elasticity while ensuring a strong connection. This results in better performance during use and meets the demands of competitions.

Description

Technical Field

[0001] This utility model belongs to the field of sports equipment technology, specifically a cork ping-pong paddle. Background Technology

[0002] The ping-pong paddle is the main tool for playing ping-pong. It was originally made of wood with a smooth surface. In 1902, the British invented the pimpled rubber paddle, which gave the ping-pong ball spin. In the 1950s, the Austrians and the Japanese invented thick sponge paddles and soft sponge paddles, which increased the ball speed, thus ushering in the era of sponge paddles.

[0003] A table tennis racket consists of three parts: the blade, the rubber, and the sponge. The blade is made from a single piece of wood, and either side can be covered with a flat layer of pimpled rubber, with the pimples facing outwards, and the thickness not exceeding 2 mm; or it can be covered with sponge rubber, with the total thickness not exceeding 4 mm. Rubber comes in various types, including inverted rubber, short pips, long pips, and anti-spin rubber. Inverted rubber offers good elasticity, high speed, stable shots, and minimal spin, making it suitable for close-to-the-table fast attacks; inverted rubber provides strong spin, stable shots, and easy control, making it suitable for topspin or topspin-plus-fast-attack styles. Common table tennis rackets mainly include those with inverted rubber and sponge, rubber rackets, and rackets with inverted rubber and sponge. However, existing table tennis rackets use sponge to increase ball speed. But for certain competitions, a full-wood racket is required. There are three main types: First, a bare wood racket (internationally known as "BareWood"); second, a hardwood racket (internationally known as "Hardbat") with a 1.3mm pimpled rubber surface; and third, a sandpaper racket with 0.1mm 240-degree sandpaper. All three types of rackets require 100% wood for competition. Therefore, there is an urgent need for a table tennis racket that can increase ball speed to a certain extent without the need for sponge. Utility Model Content

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: This utility model discloses a cork ping-pong paddle, comprising a solid wood layer and cork layers attached to both sides of the solid wood layer. The cork layers are fixedly connected to the solid wood layer by an adhesive layer or by insertion. The adhesive layer is double-sided adhesive. The thickness of the solid wood layer is 5-8mm, and the thickness of the cork layer is 2-3mm.

[0005] Preferably, the side of the cork layer away from the solid wood layer is connected to a rubber layer or a sandpaper layer via an adhesive layer.

[0006] Preferably, the thickness of the rubber layer is 1.1-1.5 mm, and the thickness of the sandpaper layer is 0.1-0.3 mm.

[0007] Preferably, the thickness of the adhesive layer is 0.1-0.2 mm.

[0008] Preferably, it also includes a handle that is fixedly connected to or integrally formed with the end of the solid wood layer.

[0009] Preferably, patches are provided on both sides.

[0010] Preferably, the insertion is specifically provided with mutually cooperating protrusions and grooves on the contact surfaces of the solid wood layer and the cork layer, so that the solid wood layer and the cork layer are fixed when the protrusion is embedded in the groove.

[0011] Preferably, the protrusions and grooves are respectively disposed on either the solid wood layer or the cork layer.

[0012] Compared with the prior art, the technical solution provided by this utility model has the following advantages: This utility model discloses a cork table tennis racket, comprising a solid wood layer and cork layers adhered to both sides of the solid wood layer. The cork layers are fixedly connected to the solid wood layer by an adhesive layer or by insertion. The adhesive layer is double-sided adhesive. The thickness of the solid wood layer is 5-8mm, and the thickness of the cork layer is 2-3mm. By replacing the sponge layer with a cork layer 300, the cork layer 300 is more durable and robust than the sponge layer. Furthermore, the cork layer 300 is connected to the solid wood layer 100 via double-sided adhesive, which offers better elasticity compared to traditional glue connections. This is because glue forms a plastic layer after solidification, lacking elasticity, while double-sided adhesive provides a certain degree of elasticity while ensuring a strong connection. This results in better performance of the table tennis racket during use and meets the demands of competitions. Attached Figure Description

As a result, the ping-pong paddle performs better during use and can meet the requirements of competitions.

[0022] Example 2 See attached document Figure 2 This embodiment of a cork ping-pong paddle includes a solid wood layer 100 and cork layers 300 adhered to both sides of the solid wood layer 100. The cork layers 300 are fixedly connected to the solid wood layer 100 by an adhesive layer 200, which is double-sided adhesive. The thickness of the solid wood layer 100 is 5-8 mm, and the thickness of the cork layer 300 is 2-3 mm. A rubber layer 400 or a sandpaper layer is connected to the side of the cork layer 300 away from the solid wood layer 100 via the adhesive layer 200. The thickness of the rubber layer 400 is 1.1-1.5 mm, and the thickness of the sandpaper layer is 0.1-0.3 mm. The thickness of the adhesive layer 200 is 0.1-0.2 mm. It also includes a grip 500 fixedly connected to or integrally formed with the end of the solid wood layer 100. Patches are provided on both sides of the grip 500.

[0023] This embodiment of a cork ping-pong paddle uses a cork layer 300 instead of a sponge layer. Compared to a sponge layer, the cork layer 300 is more durable and sturdy. The cork layer 300 is connected to the solid wood layer 100 with double-sided tape, which provides better elasticity than the traditional method of connecting with glue. This is because glue forms a plastic layer after solidification, which lacks elasticity, while double-sided tape provides a certain degree of elasticity while ensuring a strong connection. As a result, the ping-pong paddle performs better during use and can meet the requirements of competitions.

[0024] Example 3 See attached document Figure 3 This embodiment of a cork ping-pong paddle includes a solid wood layer 100 and cork layers 300 adhered to both sides of the solid wood layer 100. The cork layers 300 are inserted into and fixedly connected to the solid wood layer 100. The thickness of the solid wood layer 100 is 5-8 mm, and the thickness of the cork layer 300 is 2-3 mm. A rubber layer 400 or a sandpaper layer is connected to the side of the cork layer 300 away from the solid wood layer 100 via an adhesive layer 200. The adhesive layer 200 is double-sided adhesive.

[0025] The thickness of the rubber layer 400 is 1.1-1.5mm, and the thickness of the sandpaper layer is 0.1-0.3mm.

[0026] The thickness of the adhesive layer 200 is 0.1-0.2 mm.

[0027] It also includes a grip 500 that is fixedly connected to or integrally formed with the end of the solid wood layer 100.

[0028] The 500 has patches on both sides.

[0029] The insertion method specifically involves providing mutually cooperating protrusions 110 and grooves 210 on the contact surfaces of the solid wood layer 100 and the cork layer 300, so that the solid wood layer 100 and the cork layer 300 are fixed when the protrusion 110 is embedded in the groove 210. The protrusion 110 and the groove 210 are respectively provided on either the solid wood layer 100 or the cork layer 300.

[0030] In this embodiment, a cork ping-pong paddle is provided, in which a cork layer 300 replaces a sponge layer. Compared to a sponge layer, the cork layer 300 is more durable and sturdy. The solid wood layer 100 and the cork layer 300 are fixed together by protrusions 110 and grooves 210. Compared to fixing with glue or double-sided tape, the fixation is more reliable and the paddle is more durable.

[0031] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent.
