Lengthened body side positioning plate type table tennis big arm corrector

Abstract

The utility model provides a lengthened body side positioning plate type table tennis big arm corrector, and aims to solve the problem that when CN215938975U is carried, clothes and even skin of a user in contact with a body side positioning plate are ground by the body side positioning plate. The main points of the utility model are as follows: the longitudinal length of a body side positioning plate is increased in a manner that the bottom edge of the body side positioning plate extends downwards, so that the longitudinal length of the body side positioning plate is greater than the transverse length, and the orthographic projection of the body side positioning plate is a longitudinal rectangle; and the longitudinal lengths of the body side positioning plate and the bandage are the same. Due to the fact that the area of the longitudinally-lengthened body side positioning plate is remarkably increased, correspondingly, the contact area between the body side positioning plate and the body and the friction force between the body side positioning plate and the body are remarkably increased, the firmness of the body side positioning plate on the body of a user is improved, and the phenomenon that the coat and even the skin of the user are abraded is avoided.

Description

Technical Field

[0001] The utility model relates to a large arm corrector for training table tennis forehand attacking. Background Art

[0002] CN209137901U discloses a device for training and shaping the upper arm for forehand attacks in table tennis. The device comprises an upper arm support plate 1 with an upper arm strap 5, an underarm limit plate 2, a side positioning plate 3, and a chest strap 6 (also known as a side positioning plate strap). The underarm limit plate 2 effectively limits the angle between the upper arm and the side of the body, correcting the incorrect batting posture of table tennis beginners (hereinafter referred to as "beginners") (see paragraphs 4 and 12 of the specification). This incorrect batting posture refers to the situation where the upper arm moves while the body remains stationary during the stroke, meaning the angle is unrestricted and often exceeds 35°, causing the ball to fly off the table. The effect of CN209137901U is that when a beginner wears (uses) the device and strikes the ball, the body moves along with the upper arm (i.e., corrects the angle), limiting the angle to 20-35°. The above-mentioned underarm limit plate 2 is forward-bent, the arc-shaped top of the underarm limit plate is horizontal front to back, and the contour line of the underarm limit plate 2 is rectangular. When the user wears CN209137901U to practice table tennis forehand attack, the upper arm swings back and forth around the shoulder, and the upper arm leaves the front side of the body. Obviously, there is a gap in its fit with the human body.

[0003] In response to the defects of CN209137901U, CN215938975U proposed an improved solution, a table tennis upper arm corrector that fits the human body. Specifically, the curved top 11 of the underarm limit plate 1 is tilted higher in the front and lower in the back. Correspondingly, the upper arm support plate 2 relative to the side limit plate is also tilted higher in the front and lower in the back. When the user wears it to practice forehand attacking in table tennis, it fits the user's body better.

[0004] According to the respective drawings disclosed in CN209137901U and CN215938975U, the orthographic projection of the side positioning plate is a rectangle, which has two dimensions: longitudinal length (referring to the distance from the top to the bottom of the side positioning plate) and transverse length (referring to the length of the side of the orthographic projection of the top or bottom); its transverse length is greater than its longitudinal length. This article calls such a rectangle that is long horizontally and short in length a transverse rectangle, and a rectangle that is short in length and long horizontally is a longitudinal rectangle. Obviously, the orthographic projection of the above-mentioned side positioning plate is a transverse rectangle; CN209137901U Figure 3 Disclosed are a side positioning plate and a strap thereof, both having the same longitudinal length.

[0005] After wearing the CN215938975U for a while, users discovered that the side locating plates rubbed their clothing and even their skin. This indicates that the side locating plates moved relative to the user's body during forehand attacks, indicating that the side locating plates were not yet fully integrated with the user's body and that the side locating plates were not yet fully secured (positioned). This was due to the side locating plates being too short in length, resulting in a small contact area with the body. Summary of the Invention

[0006] In order to solve the above technical problems, the purpose of the utility model is to provide a table tennis upper arm corrector with an extended side positioning plate.

[0007] The purpose of the present utility model is achieved in this way: it includes an underarm limiting plate, a side positioning plate and its straps, the side positioning plate includes a bottom edge, the arc-shaped top of the underarm limiting plate is inclined in a front-high and back-low manner, and its characteristics are: the bottom edge of the side positioning plate increases the longitudinal length of the side positioning plate in a downward extension manner, so that the longitudinal length of the side positioning plate is greater than the transverse length, and the positive projection of the side positioning plate becomes a longitudinal rectangle; the side positioning plate and its straps have the same longitudinal length.

[0008] Except for the above changes in the side positioning plates and their straps, the other technical features are the same as those of CN215938975U. The way a user puts on the utility model is the same as that of CN215938975U.

[0009] Compared with CN215938975U, the positive effect of the present invention is that the area of ​​the longitudinally lengthened side positioning plate is significantly increased, and accordingly, the contact area between the side positioning plate and the body and the friction generated between the two are significantly increased, so that the firmness of the side positioning plate on the user is increased, and no relative movement is generated between the two, thereby avoiding the phenomenon of the user's upper clothes or even skin being rubbed. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention will be further described below with reference to the accompanying drawings.

[0011] Figure 1 It is a schematic diagram of the present utility model.

[0012] Figure 2 yes Figure 1 A-direction view.

[0013] Figure 3 It is a schematic diagram of a user wearing the utility model. DETAILED DESCRIPTION

[0014] See also Figure 1 and 2, consists of an upper arm support plate 3, an underarm limit plate 2, a side positioning plate 1 and its strap 4. The side positioning plate 1 includes a bottom edge, the arc-shaped top of the underarm limit plate is inclined in a high front and low back type, and the bottom edge of the side positioning plate 1 extends downward to the user's lowest rib. The longitudinal length of the side positioning plate is greater than its transverse length. The orthographic projection of the side positioning plate forms a longitudinal rectangle. At this time, the longitudinal length of the side positioning plate 1 is about twice the longitudinal length of the upper arm support plate 3; the longitudinal length of the side positioning plate 1 is the same as the longitudinal length of the side positioning plate strap 4 (also called the width of the side positioning plate strap 4), see Figure 3 .

[0015] The way of putting on the utility model by the user is the same as that of CN215938975U. After putting on the utility model, the body from the armpit to the user's lower ribs is covered by the side positioning plate, and after tying the same longitudinal length of the strap, the side positioning plate is firmly fixed on the user.
