Description

Suspended racquet stringing member and racket with the same

The present invention relates to a sports racquet worn with a wire mesh, and more particularly to a suspension threading member for use in the racquet threading of the sports balls and a sports racquet using the member.

According to the prior art, a sports racket provided with a wire mesh usually has a shaft handle. One end of the shaft handle is provided with a head frame, and the other end is provided with a grip. The head frame has an annular frame body on the frame body. A series of perforations are provided, and after the perforations are passed through the wire, a mesh surface composed of longitude and longitude strings is formed for the ball. In order to make the mesh surface forcefully return the ball in the future, the latitude and longitude lines must have sufficient tension, that is, the wire must be stretched on the frame of the racket, but in this case, when the mesh surface is subjected to the sphere When the impact occurs, the dynamic tension of the hitting area of the mesh surface cannot be smoothly transmitted between most of the network cables, so the network cable is very easy to break, and the dwell time of the mesh surface is too short, and the hitter cannot effectively control the back. The strength and direction of the ball.

U.S. Patent Nos. 4,930,782 and 4,591,165 disclose a swaying device that smoothly transmits the dynamic tension between the strings of the sports racquet. In practice, the aforementioned oscillating device is placed in the racquet head frame. Between the adjacent string holes. Each of the oscillating means is constituted by an elongated member having a length almost equal to the distance between two adjacent chord holes, and the upper surface of each of the oscillating means has a groove for accommodating a string. When assembled, a string first passes outward through a first chord hole (above the oscillating device) and then inwardly through an adjacent second chord hole. This string thus passes through the swinging device. When tensioned, adjacent strings (which hold the oscillating device) apply an inward force on the oscillating device. The force on the string is transmitted to the racket frame via the swinging device. When the string is subjected to different tensions, the curved bottom surface of the oscillating device causes a swing, which allows tension on one string to be transmitted to the adjacent string.

However, these rackets still have problems in assembly and use. For example, it is difficult to keep individual swinging devices in place during stringing. As long as one string is broken, some or all of the swinging devices will be lost from the racket, and the ground may be lost on the court. Furthermore, as shown in Fig. 11 of the 4,930,782 patent, when the swinging device is swayed by force, the string will be in close contact with the wall of the threading hole, that is, there will be friction between the racket frame and the string, The tension will still not pass smoothly between the strings.

The tennis racket uses the first preferred embodiment of the suspended racket stringing member of the present invention to set up a network cable. The lower, left and right parts are displayed in a cross-sectional view. The tennis racket 90 has a shank 92. One end of the shank 92 is provided with an annular head frame 94, and the other end is provided with a grip 96. The head frame 94 and the grip 96 are in the same plane.

The head frame 94 has an outer side surface 942 and an inner side surface 944. The outer side surface 942 is provided with a channel 946 defining an annular hollow portion 98. The mesh 100 is formed by a plurality of threaded holes through the head frame 94 to form a ball striking surface at the hollow portion 98. In detail, the head frame 94 is provided with a plurality of threading holes extending through the inner and outer surfaces 942, 944. In general, the threading holes can be generally divided into two groups, one of which is a long axis group threading hole 102, each threading hole 102 is parallel to the long axis of the head frame 94, and is spaced apart to accommodate the long axis. cable. The other is a horizontal axis group threading hole 104, each threading hole 104 is parallel to the short axis of the head frame 94, and is spaced apart to accommodate the short-axis network cable, and each long-axis network cable and each short-axis network cable are woven into the same. Batting the net. It must be mentioned here that the racket that can be used to thread the cable by the present invention may also be a racket of other shapes and structures, such as a badminton racket, a badminton racket, and the like.

Referring to the second, third and fourth figures, the suspended racquet stringing member 10 can be made of a lighter metal material such as an aluminum alloy or a titanium alloy, and of course can be molded by a plastic material.

The threading member 10 has an elongated base 12 and two threaded posts 14. The base 12 has a top side surface 16, a bottom side surface 18, and a guide groove 20 extending along the major axis of the base 12. The guide groove 20 has two open ends 202 on both sides of the long axis.

Each of the threading posts 14 extends from the two axial ends of the bottom side surface 18 of the base 12 in a direction away from the top side surface 16, and has a column length approximately equal to each of the threading holes 102, 104. Each of the threading posts 14 is respectively provided with a guiding hole 142 extending along the column axis thereof. The guiding hole 142 has an inlet port 144 and an outlet port 146. Each of the inlet ports 144 corresponds to each of the open ends 202 of the guide groove 20. The outer diameter of each threading post 14 is slightly smaller than the aperture of each of the threading holes 102, 104 for being insertable into each of the threading holes 102, 104. The hole diameter of the guide hole 142 of each threading post 14 is larger than the wire diameter of the racket wire.

In addition, the base 12 guiding groove 20 has an arcuately extending bottom surface 204. Two portions of the curved bottom surface 204 corresponding to the respective open ends 202 are respectively provided with a hanging portion 30 protruding outwardly by an appropriate length. The length of the suspension portion 30 is such that the wire 100 is suspended from the guide hole 142 at the entrance 144 of the guide hole 142 without touching the hole wall 148. The suspension portion 30 of the embodiment is a The ridge-shaped projections are provided with an arcuate surface 302 for allowing the mesh 100 to move more smoothly.

When the racquet 90 is passed through the wire 100, the pedestal 12 of the member 10 is placed in the channel 946, and the bottom side surface 18 is attached to the groove surface of the channel 946. Each threading post 14 is respectively embedded in two adjacent threading holes 102. After passing through the guiding holes 142, the two adjacent mesh wires are formed into a string segment 106 which is received in the guiding groove 20 of the base 12 and attached to the curved bottom surface 204. Both ends of the string segment 106 are attached to the curved surface 302 of each of the suspension portions 30 and enter and exit the guide holes 142 from the inlet port 144.

The manner in which the component 10 is threaded through the wire can be clearly seen from the third figure. The two ends of the wire 100 segment 106 are respectively passed through the guiding holes 142 of the threading post 14 in a hanging manner. The wire 100 does not contact the hole wall 148 of the guide hole 142. In this way, when the racket hits the ball with its mesh surface, the dynamic tension of the netting group in the hitting zone is smoothly and evenly transmitted to other network cables.

In addition, in order to have the mesh surface have more vertically extending mesh lines, as shown in the fourth figure, the bottom side surface 18 of the member 10 can be designed to be inclined by a predetermined angle in conjunction with the groove surface of the racquet head frame 94 channel 946.

From the foregoing detailed description of the structure of the threading member 10 and the manner in which it is disposed on the racket 90 head frame 94, it can be clearly understood that when the ball hits the net laid by the wire 100 at the hollow portion 98 of the head frame 94 In the case of the face, the wire group of the hit zone will elongate, and the kinetic energy of the ball will be stored in the form of tension energy on the elongated wire and transmitted to the other wire through the threading member 10. Since the wires are not in contact with the hole wall 148 of the guiding hole 142, and the member 10 is fixed to the head frame 94, the dynamic tension generated by the hitting area of the mesh hitting area is any In this case, it will be smoothly and evenly transmitted to other network cables through the network cable group of the hitting area.

Referring to the fifth and sixth figures, the present invention can also be made into a suspended racquet stringing member as shown in FIG. 40.

The suspended racquet threading member 40 is substantially identical in construction to the member 10, the difference being in the design of the threading posts. The member 40 also has two threading posts 42, the length of each threading post 42 being shorter than the length of the threading holes 102, 104 of the racket 90, so that when the member 40 is placed with the racket head frame 94, each threading post 42 will only be jammed. Portions of the respective threading holes 102, 104 are not in contact with the outlet ports 110 of the respective threading holes 102, 104. In other words, the actual inlet port of the wire is the wire inlet port 44 of the threading post 42, and the actual outlet port is the outlet port 110 of each threading hole 102, 104. Since the outer diameter of each threading post 42 is smaller than the diameter of each of the threading holes 102, 104, the inner diameter of the inlet port 44 must be smaller than the diameter of the outlet port 110, whereby the wire 100 is not more than the threading hole. The walls of the holes 102, 104 are in contact, which makes the transmission of tension smoother and evener. In this embodiment, each of the threading posts 42 has a semi-circular shape, that is, each of the threading posts 42 has a semi-cylindrical body portion 46 and an open channel 48, thereby reducing the network cable. The probability of contact with the hole wall 52 of each of the threading posts 42 guiding holes 50.

Next, with reference to the seventh and eighth figures, another embodiment of the suspension racquet threading member of the present invention, as shown in FIG. 60, has a base 62 and a threading post 64.

The base 62 has a top side surface 622, a bottom side surface 624 and a guiding groove 626. The threading post 64 has a guiding hole 642 extending along the column axis thereof. The guiding hole 642 has an inlet port 644, and an outlet port 646. The inlet port 644 is in communication with the guiding groove 626. The length of the threading post 64 can be designed to be less than the length of the racquet threading hole, and the diameter of the guiding hole 642 is greater than the wire diameter of the racquet wire.

The guiding groove 626 has an open end 628 and an arcuately extending bottom surface 630. A portion of the arcuate bottom surface 630 corresponding to the inlet port 644 of the guiding hole 642 is provided with a hanging portion 632. In the embodiment, the hanging portion 632 is a curved surface. When the wire is threaded by the member 60, the wire 100 will enter and exit the guiding hole 642 from the wire inlet 644 by being suspended by the hanging portion 632, thereby reducing the probability of the wire 100 contacting the hole wall 648. . Furthermore, due to the presence of the suspension portion 632, the diameter of the inlet port 644 of the guide hole 642 is made smaller than the diameter of the outlet port 646. Therefore, the aforementioned advantages are more apparent. Further, it must be noted that, as shown in the eighth figure, when the member 60 is disposed with the racquet head frame 94, a member 60 may be disposed in each of the adjacent two threading holes 102, and the open ends 628 of the members 60 may be opposite. Thus, the advantages of the present invention can be exhibited on the overall racket.

Finally, with reference to the ninth and tenth drawings, still another embodiment of the suspension racquet threading member of the present invention, as shown in FIG. 70, has a base 72 and a threading post 74.

The base 72 has a top side surface 722, a bottom side surface 724 and a guiding slot 726. The threading post 74 has a guiding hole 742 extending along the column axis thereof. The guiding hole 742 has an inlet opening 744 and an outlet opening 746. The inlet opening 744 is in communication with the guiding slot 726. The length of the threading post 74 can be designed to be less than the length of the racquet threading hole, and the diameter of the guiding hole 742 is greater than the wire diameter of the racquet wire.

The guiding groove 726 has two open ends 728, 730, two arc-shaped bottom surfaces 732, 734 extending from the respective open ends 728, 730 to the inlet port 744, and each of the arc-shaped bottom surfaces 732, 734 corresponding to the inlet port 744 is respectively provided with a hanging portion 736, 738. In the embodiment, the suspension portions 736, 738 are both a curved projection. Thereby, when the wire 100 enters and exits the wire inlet 744 via the open end 728 or 730 of the guiding groove 726, it can pass through the guiding hole 742 without contacting the hole 748 of the guiding hole 742. Similarly, due to the presence of the suspension portions 736, 738, the diameter of the inlet port 744 of the guide hole 742 will be smaller than the diameter of the outlet port 746. Therefore, the aforementioned advantages are more apparent. Further, as shown in the tenth figure, when the member 70 is disposed in the racquet head frame 94, a member 70 can be disposed in each of the adjacent two threading holes 102, and thus, the advantages of the present invention can be exhibited on the entire racquet.
