Description

Badminton racket handle tail cap

This novel invention relates to the structure of a badminton racket, especially the tail cap structure of the handle of a badminton racket.

The structure of a badminton racket consists of three parts: the head frame, the middle tube and the grip. The head frame is threaded to form the hitting surface, and the head frame is connected to the grip through the middle tube. The grip of a traditional badminton racket is usually made of stronger and less prone to breaking wood. In addition to the fact that wood is easy to obtain, easy to process, and low in price, wood has a good damping effect, which helps absorb the vibration generated when the racket hits the ball.

In the approved Republic of China new patent certificate No. M597158, a badminton racket handle and back cover are proposed; wherein the handle includes a body and a back cover; one end of the body is connected to the middle tube; the back cover includes a bottom plate, a plurality of side walls, a receiving portion and a plurality of hollow structures, the side walls are connected to the bottom plate; the receiving portion is formed by the side walls and the bottom plate, and the receiving portion is sleeved on the other end of the body; the hollow structures are located on part of the side walls. The back cover further has at least one rib, which is arranged in one of the hollow structures. The back cover further has at least one protrusion, which is arranged on the bottom plate, and the protrusion abuts against the body. The back cover further has at least one hook, which is located at the second end of the side wall, and the hook engages and fixes the body.

The rear cover proposed in the above patent technology is a component made of plastic material by injection molding technology. Some of the side walls of the rear cover have a hollow structure, so that the rear cover is fixed to the main body by hook engagement. The bottom plate of the rear cover has at least one convex portion, and the convex portion is used to support the main body. The hollow structure of the multiple side walls will weaken the structural strength of the rear cover, which is easily damaged by external force. On the other hand, the bottom plate of the rear cover has at least one protrusion, which is used to support the main body, but these protrusions are designed on at least one rib of the hollow structure. These thin and fragile structures are easily damaged or broken due to external impact, such as the impact caused by a badminton racket falling to the ground.

The technical problem to be solved by this new model is to provide a badminton racket handle tail cap with excellent structural strength and lightweight advantages.

The present invention proposes a tail cap for a badminton racket handle, wherein the tail cap is assembled at the tail end of the tubular badminton racket handle and is interlocked with a hook on both sides of the badminton racket handle near the tail end; wherein the tail cap is a component made of plastic material by one-piece injection molding, and the structure of the tail cap includes: an inner sleeve, an outer sleeve and a bottom plate; the inner sleeve and the outer sleeve are coaxially arranged on one side surface of the bottom plate, and there is a gap between the inner sleeve and the outer sleeve, so that the tube wall of the badminton racket handle can be inserted into the gap from top to bottom, and the outer wall of the outer sleeve has a plurality of ribs extending outward along the radiation direction, and the bottom of the ribs is connected to the bottom plate, and a hole is provided at the position of the inner sleeve corresponding to the hook.

As a preferred embodiment of the tail cap of the new badminton racket handle, the gap is wide at the top and narrow at the bottom, and the lower part of the gap can form a tight fit with the tube wall of the badminton racket handle.

As a preferred embodiment of the tail cap of the new badminton racket grip, the cross-sectional shape of the tube wall of the inner sleeve and the outer sleeve is a trapezoid that is narrow at the top and wide at the bottom.

The advantages and functions of the tail cap of the new badminton racket grip are that the tail cap is a component made of plastic material by one-piece injection molding, wherein the inner sleeve and the outer sleeve are connected to the bottom plate as a whole, and the outer wall of the outer sleeve is connected to the bottom plate by several ribs extending outward along the radiation direction, which has excellent structural strength. Even if the badminton racket falls, it will not be easily broken or separated; on the other hand, since the tail cap omits the outer shell design, the overall structure of the tail cap has the advantage of being lightweight.

The specific implementation method, technical features and effects of this new model will be described below with accompanying drawings.

In the embodiments disclosed in the patent specification and drawings of this new type, the directions mentioned therein (such as up, down, left, right, front and back) are based on the contents shown in the drawings and are used to illustrate the relative relationship between the various elements or structures in the embodiments (such as position relationship, connection relationship and action relationship). In principle, when the positions of the elements or structures mentioned in the specification of this new type match those shown in the drawings, the directions mentioned will be appropriate. If the positions of the elements or structures mentioned in the specification of this new type change, the directions mentioned should also be changed accordingly.

First, please refer to Figures 1 to 3, which are front views and cross-sectional views of a preferred embodiment of the tail cap of the new badminton racket grip.

The present invention proposes a tail cap 10 for a badminton racket handle. The tail cap 10 is mounted on the tail end of a badminton racket handle 50 (see FIG. 4), especially the tail end of a tubular badminton racket handle 50. As shown in FIG. 5, the badminton racket handle 50 is a hollow tubular component. There are two opposite positions on both sides of the badminton racket handle 50. The hook 51 is used to be hooked and combined with the tail cap 10 (see FIG. 4 and FIG. 5). The front end of the badminton racket handle 50 can be connected to a middle tube of the badminton racket (not shown in the figure).

A preferred embodiment of the tail cap 10 of the badminton racket handle 50 proposed in the present invention comprises: an inner sleeve 20, an outer sleeve 30 and a bottom plate 40; the tail cap 10 is a component made by one-piece injection molding of plastic material.

The inner sleeve 20 and the outer sleeve 30 are coaxially disposed on one side of the bottom plate 40. There is a gap G between the inner sleeve 20 and the outer sleeve 30 (see FIG. 2 and FIG. 3). From a cross-sectional perspective, the gap G is designed to be wide at the top and narrow at the bottom so that the wall of the badminton racket handle 50 can be smoothly inserted into the gap G from top to bottom. In the embodiment, the lower part of the gap G can form a close fit with the tube wall of the badminton racket handle 50; in another preferred embodiment, from a cross-sectional perspective, the cross-sectional shape of the tube wall of the inner sleeve 20 and the outer sleeve 30 is a trapezoidal shape that is narrow at the top and wide at the bottom, so as to obtain better structural strength and facilitate demolding of the tail cover 10 after injection molding.

The inner sleeve 20 is provided with a hole 21 (or a groove) at the position corresponding to the hook 51. After the tail end of the badminton racket handle 50 is inserted into the gap G, the badminton racket handle 50 can be hooked and combined with the hook 51 and the hole 21 (see Figures 4 and 5). Through the tight fit of the gap G or the adhesive effect of the adhesive, the tail cover 10 can be firmly assembled on the tail end of the badminton racket handle 50 and is not easy to fall off.

The shapes of the inner sleeve 20 and the outer sleeve 30 in the radial plane match the cross-sectional shape of the badminton racket handle 50. Generally speaking, the cross-sectional shape of the badminton racket handle 50 is a polygon, preferably an octagon, so that the user can have a variety of gripping methods and hitting angles when holding the badminton racket handle 50.

In a preferred embodiment, the outer wall of the outer sleeve 30 has a plurality of ribs 31 extending outwardly in the radiation direction, and the bottom of the ribs 31 is connected to the bottom plate 40. Preferably, the outer diameter of the bottom plate 40 is larger than the outer diameter of the outer sleeve 30, and the ribs 31 are triangular components that gradually widen from the front end of the tail cap 10 (the end relatively close to the middle tube of the badminton racket) toward the tail end of the tail cap 10, which helps the user to hold the handle 50 of the badminton racket against the lower edge of the palm through the ribs that gradually widen toward the tail end of the tail cap 10, and can prevent the badminton racket from being thrown out of the hand when swinging the racket.

Although the present invention has been disclosed through the above-mentioned embodiments, it is not intended to limit the present invention.
