TECHNICAL FIELD OF THE INVENTION
The present invention relates to a racket cover for covering both sides of a hitting portion such as a badminton racket and a tennis racket.
[0002]
[Prior art]
A conventional racket cover is formed by partially sewing two pieces of synthetic leather having substantially the same shape as the hitting portion of the racket along the outer peripheral edge thereof, and attaching a fastener or the like to the unsewn outer peripheral edge as necessary. It has a structure provided. Such a conventional racket cover is used during storage or transportation of the racket, and is intended only to protect both sides of the hitting portion of the racket. Therefore, when using the racket, it is assumed that the racket cover is removed.
[0003]
On the other hand, when practicing using a racket, the player sometimes swings using a training racket that is heavier than the game racket for the purpose of strengthening muscle strength and increasing the swing speed. In such a practice racket, a material having a high specific gravity is used for a frame portion, or a core material is inserted into a hollow frame. However, such a practice racket is not very easy to use because the bending degree of the frame and the like are different from the game racket.
[0004]
Therefore, it has been attempted to practice the swing by devising a method such as attaching a detachable weight to the frame of the game racket or taping. However, there is a problem in that simply adding weight to the frame hardly changes the air resistance during swinging, so that it is not possible to grasp the sense of hitting the ball. Also, there is a problem that the method of taping or the like is cumbersome to attach and detach, and is not practical.
[0005]
[Problems to be solved by the invention]
In view of the problems of the related art, an object of the present invention is to provide a racket cover that protects both sides of a hitting portion of a racket and is excellent for practice swinging. Another object of the present invention is to provide a racket cover that can be swung with a feeling similar to that of hitting a ball because it has an appropriate air resistance when swung, and that can be easily attached and detached.
[0006]
[Means for Solving the Problems]
As a result of intensive studies to achieve the above object, the present inventor has found that the problem can be solved by forming a mesh portion at the center of the racket cover, and has provided the present invention.
[0007]
That is, the present invention can cover both surfaces of the hitting portion of the racket, and, if necessary, in a racket cover detachable from the hitting portion, covers one surface of the hitting portion and forms the hitting portion. A first covering portion having substantially the same shape as the first covering portion, covering the other surface of the hitting portion, having a shape substantially the same as the shape of the hitting portion, and facing the first covering portion. A second covering portion, a fixed connecting portion in which a part of the opposing outer peripheral edges of the first covering portion and the second covering portion are connected in an inseparable state, and a hitting portion of the racket, Openable connection in which the outer peripheral edges of the first and second covering portions other than the part facing each other are openably and closably connected so as to be able to be inserted and removed between the first and second covering portions. Part, and the first covering part and the second covering part are formed at corresponding positions in the center respectively. There is provided a racquet cover; and a mesh portion.
[0008]

[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The racket cover of the present invention is applicable to badminton rackets, tennis rackets, squash rackets, and all other sports rackets and toy rackets capable of hitting a ball or the like with a gut inside the frame. In addition, the term "ball" used in the "ball hitting portion" and the like used in the present specification does not necessarily mean only a spherical ball, and is hit with a gut surface of a badminton blade or other racket. This is a concept that includes all objects that can be created. Further, the "hitting portion" means a structural portion including a gut and a frame for setting a gut. In the following description, the present invention will be described using a racket cover for badminton rackets as an example.
[0010]
1 and 2 are front views showing a racket cover 1 according to the present invention. The racket cover 1 covers one surface of the hitting portion 5 of the racket 3, and covers a first covering portion 7 having substantially the same shape as the hitting portion 5 and the other surface of the hitting portion 5. And a second covering portion 9 having substantially the same shape as the shape of the hitting portion 5. The second covering portion 9 is arranged to face the first covering portion 7 so that The storage section 11 is formed between them.
[0011]
The outer peripheral edges facing each other are sewn 13 from one end of the outer peripheral edges of the first coating portion 7 and the second coating portion 9 over a length of approximately 60% of the length of the entire outer peripheral edge. Thus, a fixed connection portion 15 is formed in which the outer peripheral edges are inseparably connected to each other. A band-shaped peripheral protection member 14 is provided around the sewn portion 13 by sewing so as to cover the sewn portion 13 to prevent the fixed connection portion 15 from fraying and the sewing 13 from being unthreaded. Note that the fixed connection portion 15 may be formed by heat welding of the outer peripheral edges of the first coating portion 7 and the second coating portion 9 to each other or by bonding with an adhesive.
[0012]
In the present invention, the length of the sewn portion 13 between the outer peripheral edges of the first covering portion 7 and the second covering portion 9 is not particularly limited as long as it does not hinder insertion and removal of the racket. Usually, it is 70% or less, preferably 65% or less of the entire outer periphery. If importance is placed on functionality, the content is set to 50 to 65% of the entire outer peripheral edge, preferably 55 to 62%.
[0013]
At the outer peripheral edge of the first coating portion 7 and the second coating portion 9 other than the fixed connection portion 15, a fastener 17 forming a releasable connection portion is formed. As shown in FIG. 2, by opening the fastener 17, an opening 19 that allows the hitting portion 5 of the racket 3 to be inserted into or removed from the storage 11 is formed. On the other hand, by closing the fastener 17, the state where the hitting portion 5 is stored in the storage portion 11 can be maintained. In addition, other than the fastener 17, any conventionally known means that can temporarily connect surfaces to each other, such as a surface tape, and can release the connection as necessary can be applied to the openable connection portion.
[0014]
The first covering portion 7 and the second covering portion 9 have substantially the same configuration, and a mesh portion 21 is formed at a corresponding position at the center of both. The mesh portion 21 has a mesh material slightly larger than the size of the opening 23 on the inner side of the periphery of the opening 23 formed at the corresponding position at the center of each of the first covering portion 7 and the second covering portion 9. 25 is formed and sewing 13 is performed in this state.
[0015]
Although the first covering part 7 and the second covering part 9 have substantially the same shape and the same area, the mesh part 21 has an area of 15 to 40% of the area of the first covering part 7 and the second covering part 9. Preferably, it is 25 to 35% of the same area. Further, it is preferable that the mesh portion 21 has a similar shape obtained by reducing the first covering portion 7 and the second covering portion 9 which are substantially elliptical or a shape close to the similar shape. In this case, the first covering portion 7 and the second covering portion 9 have the same shape. Preferably, an interval of 4 to 8 cm is formed between the outer peripheral edge of the covering portion 9 and the outer peripheral edge of the mesh portion 21, and more preferably, an interval of 5 to 7 cm is formed.
[0016]
By forming the mesh portion 21 at such a position, when swinging the racket 3, a suitable wind pressure resistance can be felt around the mesh portion 21 in a well-balanced manner, and the mesh portion 21 allows air to pass through. Because it is possible, the swing is improved. Thereby, since an appropriate wind pressure resistance is felt in the practice of swinging the racket, when the racket cover 1 is removed and the racket 3 alone is swinged, an effect that the stroke is easily felt can be obtained.
[0017]
The mesh portion 21 may adopt any conventionally known mesh shape such as a honeycomb shape as shown in FIG. 4 or a shape in which linear members having a constant thickness are orthogonal to a lattice shape. In any of the mesh forms, the opening ratio of the mesh portion 21 is preferably 60 to 85%, and more preferably 65 to 75%. Here, the aperture ratio of the mesh portion 21 is defined by the area of the region 27 other than the portion occupied by the mesh material 25 in the entire area of the mesh portion 21 (this corresponds to the area of the portion through which air can flow). Refers to the ratio.
[0018]
By setting the aperture ratio of the mesh portion 21 as described above, it is possible to generate a constant wind pressure resistance even in the opening portion 23 including the sweet spot. Can be.
[0019]
As another embodiment of the racket cover of the present invention, an embodiment shown in FIG. 5 can be exemplified. That is, as shown in FIGS. 5A and 5B, a plurality of mesh portions (openings) 21 may be formed in the first covering portion and the second covering portion. The number of mesh portions is 1 to 100, preferably 1 to 50, and more preferably 1 to 25 in each of the first coating portion and the second coating portion. The shape of each mesh part may be the same or different. The arrangement of each mesh portion is not particularly limited, but is preferably arranged with regularity.
[0020]
【The invention's effect】
The racket cover of the present invention protects both sides of the hitting portion of the racket and is excellent for practice swinging. In particular, there is a characteristic that since there is an appropriate air resistance when swinging, swinging can be performed with a feeling similar to that of hitting a ball, and furthermore, detachment is easy.
