Abstract

PURPOSE:To easily and quickly exercise a toss before a game by exposing a rotary roller which displays selectively either the surface or back plane over a grip head and supporting the roller in the inside of a grip rotatably and so as to be stopped at a prescribed position. CONSTITUTION:In a game such as tennis, etc., it is decided whether a player selects a service game first or a court by the toss before the game is started. The toss is exercised by a method to rotate a racket as a top setting a head downward and to hit the surface or the back plane of the racket. However, this method takes much time by shoving a result to an opponent by picking up the racket so as not to change the surface and the back plane, and also, the racket is easy to be impaired. To solve such problem, the rotary roller 1 which displays selectively either the surface or back plane is exposed over the grip head 2, and also, the roller 1 is supported rotatably and so as to be stopped at the prescribed position in the inside the grip.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a racket used in sports.

[0002]

2. Description of the Related Art In sports such as tennis, generally, prior to a match, toss determines whether to provide service first or to select a court. Toss is performed by turning the racket head down and turning the racket like a top on the court, and hitting the front and back sides of the racket that fell on the court. Therefore, it is possible to distinguish the front and back of the racket by attaching a decorative thread to the racket or displaying a mark on the grip head.

[0003]

However, in this method, it is troublesome to rotate the racket over the court and pick it up so that the front and back of the racket do not change and show the result to the opponent. Also, the racket is easily scratched. The present invention aims to provide a racket that overcomes these drawbacks.

[0004]

According to the present invention for achieving the above object, a rotatable rotating portion for displaying the front and back is provided inside a grip so that the rotating portion is exposed to a grip head, and the rotating portion is rotated. Further, it is characterized in that it is configured to stop at a predetermined position and selectively display either the front side or the back side.

[0005]

[Function] The rotating part is pushed with a finger to rotate and move to the stop position, and either the front side or the back side is selectively displayed.

[0006]

EXAMPLE An example of a racket according to the present invention will be shown. Figure 1
Is a view seen from an oblique direction. 1 is a roller, 2 is a grip head, and 3 is a grip.

FIG. 2 is a left side view of the roller 1. 10
1 is an axis. Reference numerals 102 denote hemispherical recesses, which are provided at four places at intervals of 90 degrees around the axis 101. The cylindrical surface of the roller 1 has areas A, B, C with a central angle of 90 degrees as shown in FIG.
It is divided into D, and A and C are marked with a "table"
A mark indicating "back" is drawn on B and D. Figure 4
[FIG. 4] is a front view of the roller 1 when A to C are arranged in front, and represents a “table”. Similarly, FIG. 5 is a front view in the case where B to D are arranged so as to come to the front, and represents “back”. FIG. 3 is a sectional view of the roller 1 taken along the cutting plane II of FIG.

FIG. 6 is a front view of the grip head 2.
201 is a square hole. FIG. 7 is a sectional view taken along the cutting plane II-II in FIG.

FIG. 8 is a front view of the grip 3, and FIG. 9 is a sectional view taken along the cutting plane III-III, and cutting plane IV-.
The cut surface cut by IV is shown in FIG. The support plate 301 has a hole 303. Further, there is a notch in a U shape, and there are a leaf spring portion 305 and a hemispherical convex portion 306. Support plate 302
There is a hole 304 in it.

FIG. 11 shows a roller 1 and a grip head 2.
It is a figure which shows the place which was integrated in the grip 3. Axis 1
01 passes through the holes 301 and 302, and the roller 1 rotates about the shaft 101 both clockwise and counterclockwise. The roller 1 by the square hole 201 of the grip head 2
Is exposed to the outside, and the roller 1 can be rotated by pushing up or down the exposed portion with a finger. 12 and 13 show cut surfaces taken along the cut surface VV in FIG. FIG. 12 shows a case where the hemispherical concave portion 102 and the hemispherical convex portion 306 are aligned and fitted to each other. Such a state will be called a stop position. Figure 13
This is the case where the former and the latter are in different positions. Leaf spring 305
Has elasticity and is in a state of being warped by being pushed in the direction opposite to the roller 1. To move from the stop position in FIG. 12 to the state in FIG. 13, an extra force is required against the elasticity of the leaf spring portion 305, and therefore the roller 1 may move by vibration or the like at the stop position. There is no.

When the roller 1 is rotated, there is a hemispherical recessed portion 102 every 90 degrees, and the roller 1 comes to a stop position. As described above, the "front" and "back" marks shown in FIGS. 4 and 5 are alternately drawn every 90 degrees on the cylindrical surface of the roller 1, and the mark is displayed through the square hole 201 at the stop position. To be done. This state is shown in FIGS. That is, when the roller 1 is rotated, the display of the "table" of FIG.
The display of "back" of 5 will be repeated. Make the grip head invisible to your opponent, turn the roller 1 with your finger, set either "front" or "back" to the display, and make either one hit the opponent to toss.

The mechanism for stopping the roller 1 at the correct position and preventing it from freely moving due to vibration or the like is not limited to the method described in the above embodiment. Further, in the above embodiment,
The stop position of the roller 1 is every 90 degrees, but it is not limited to this. For example, the cylinder surface may be divided by 180 degrees and the "front" and "back" marks may be drawn to make the stop position every 180 degrees. . The rotation angle of the roller 1 is 360 rotations.
Instead of 180 degrees, for example, it may be limited to 180 degrees and the part may be reciprocated. Further, the roller 1 may have a portion to be pressed with a finger and a portion to display a mark separately, and they may be, for example, a quadrangular prism instead of a cylinder.

FIG. 16 shows a front view of the roller 4, which is one of the modified examples of the roller 1. 17 is a left side view,
FIG. 18 is a right side view. Shaft 401, hemispherical recess 402
Are the same as the shaft 101 and the hemispherical recess 102. Reference numeral 403 denotes a cylindrical portion, which is pressed by a finger to rotate it. Reference numeral 404 denotes a square column portion, and the faces E and G have the same "front" as FIG. 3 and the faces F and H have the same "back" as FIG. The object of the present invention can be achieved by combining the roller 4 with the grip head 2 and the grip 3 instead of the roller 1.

[0014]

The racket of the present invention has a grip inside,
A rotatable rotating part that displays the front and back is provided, the rotating part is exposed to the grip head, and the rotating part is rotated to selectively display either the front or back, so that the racket itself does not rotate and fall. You can toss quickly. Also, the racket will not be damaged due to the fall of rotation.
