Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem that a bearing of a joystick structure provided at a joystick device usually used for a game machine is generally constituted to have a bowl-shaped bearing for supporting a region abutting on a joystick shaft with a surface, but in such a case, it is necessary to machine it so that the spherical shape of the abutting region of the joystick shaft coincides with the bowl-shaped surface shape of the abutting region of the bearing and it is technically difficult to machine it into such a spherical (bowl) shape as to make both shapes coincident. <P>SOLUTION: The joystick structure includes a spherical joystick shaft that can come in contact with the bearing, and the bearing for supporting the spherical joystick shaft in line contact. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a structure of a joystick structure provided in a joystick or the like.

  Usually, a joystick shaft (0102) for supporting a joystick shaft of a joystick structure (0101) provided in a joystick device used in a game machine is a joystick shaft (0102) having a spherical contact area that can come into contact with the bearing as shown in FIG. On the other hand, the bearing is generally configured to include a bowl-shaped bearing (0103) that supports a region in contact with the joystick shaft by a surface.

  By the way, when taking such a structure, it is necessary to process so that the shape of the spherical surface which is the contact area of the joystick shaft and the shape of the bowl-shaped surface which is the contact area of the bearing match. This is because if the shapes do not match, the joystick shaft will rattle in the bearing.

  However, there is a problem that it is technically difficult to process into a spherical shape that matches both shapes.

  Therefore, the technique described in Patent Document 1 is provided. Specifically, it is a joystick device provided with a crank that can move in each of the X-axis and Y-axis directions to suppress the play of the joystick shaft.

  However, although the technique described in Patent Document 1 can suppress rattling, there is a problem that the operation feeling during joystick operation is different because a crank that is not provided in a conventional joystick device is provided.

  Therefore, in view of the above problems, the present invention provides a joystick structure in which a region that can be contacted with a bearing is a spherical joystick shaft and a bearing for supporting the shaft by linear contact. Specifically, the joystick structure is as follows.

  The first invention provides a joystick structure having a joystick shaft having a spherical contact area that can contact the bearing, and a bearing that indicates the joystick shaft in line contact.

  The second invention provides a joystick structure having a bearing surface having a bearing space of an inverted truncated cone receiving a contact area on the basis of the first invention.

  The third invention provides a joystick structure whose inner wall is inclined at an angle of 30 to 45 degrees with respect to one surface of the bearing space based on the second invention.

  The fourth invention is based on any one of the second invention and the third invention, and the combination of the inner wall material of the bearing space and the contact region material of the joystick shaft is a combination of POM and nylon 6. Provide a joystick structure.

  According to the present invention, it is possible to prevent the joystick shaft from rattling in a bearing for supporting the joystick shaft. As a result, it is possible to improve the response delay of the stick operation and improve the operability.

  Embodiment 1

    <Summary of Embodiment 1>

  As shown in FIG. 2, the joystick structure of the present embodiment is a joystick structure (0201) that is assumed to be provided in a joystick device. The joystick structure of this embodiment includes a joystick shaft (0202) for a user to hold and operate, and a bearing (0203) for supporting the joystick shaft (0202).

  The joystick shaft structure of the present embodiment is characterized in that the bearing (0203) supports the joystick shaft (0202) by line contact as shown in the figure.

  <Embodiment 1: Configuration>

    ≪Joystick shaft≫

  The “joystick shaft” (0202) is a joystick shaft having a spherical contact area that can come into contact with the bearing. Specifically, the stick (operating rod / lever) has a spherical surface in contact with the bearing in the joystick shaft.

  FIG. 3 shows an example of a joystick shaft in the present embodiment. The joystick shaft of the present embodiment includes a shaft (0302) for a user to hold and a contact part (0304) having a contact area for contacting a bearing.

  In addition, although the joystick shaft in this embodiment gave an example in the case of the aggregate | assembly of the different components comprised from a shaft and a contact component, it is not limited only to it actually. For example, the shaft and the abutting part may be composed of one part. Moreover,

    ≪Bearing≫

  “Bearing” (0203) is a bearing that supports the joystick shaft in line contact. Specifically, the joystick shaft is supported by directly supporting the contact area (0304) of the joystick shaft.

  4 and 5 actually show an example of the bearing in the present embodiment. The bearing of this embodiment is a bearing provided with a cylindrical space as an area for receiving a bearing contact area as shown in FIG. As shown in FIG. 5, the bearing of the present embodiment is such that a joystick shaft is inserted into a bearing, and a contact area of the joystick shaft is brought into contact with a cylindrical space to be supported by line contact (FIG. 5A is an example). Fig. 5B shows an image of a sectional view before insertion, Fig. 5B shows an image of a sectional view after insertion, and Fig. 5C shows a perspective view and a contact surface after insertion.

  The joystick structure of the present embodiment may further have the following functions.

  ≪Stick operation sensitivity adjustment function≫

  FIG. 6 shows a sensitivity adjustment cap (0605) for adjusting sensitivity by operating the joystick shaft by being attached to the lower end of the joystick shaft (0602). As shown in FIG. 7, the sensitivity adjustment cap (0705) is used so as to be fitted to the lower end of the joystick shaft. As a result, the movable range of the joystick shaft can be narrowed. Therefore, the micro switch ON / OFF input for detecting the operation direction provided in the joystick structure can be performed by slightly tilting the stick.

  <Embodiment 1: Effect>

  The play of the joystick shaft can be eliminated by the joystick structure that supports the contact area of the joystick shaft and the bearing in line contact in this embodiment.

  << Embodiment 2 >>

    <Summary of Embodiment 2>

  In the joystick structure of the present embodiment, as shown in FIGS. 8A and 8B, the bearing space (0803) for receiving the contact region in the bearing for supporting the joystick shaft (0802) has a shape of an inverted truncated cone. FIG. 8A shows the joystick structure after insertion, and FIG. 8B shows the joystick shaft after insertion.

      ≪Bearing space≫

  The “bearing space” (0803) is a space of an inverted truncated cone that receives the contact area provided in the bearing. Specifically, it is a space in the shape of a truncated cone for supporting a contact area of a joystick shaft provided in the bearing.

  9 and 10 are views showing an example of a bearing surface in the present embodiment. As shown in FIG. 9, the bearing space of the present embodiment is a bearing surface having an inverted frustoconical space. As shown in FIG. 10, the bearing surface of the present embodiment supports the contact area of the joystick shaft by line contact (circular contact).

    ≪Inner wall angle of bearing space≫

  Here, the bearing space of the present embodiment may have a structure in which the inner wall is inclined at an angle of 30 degrees to 45 degrees with respect to the joystick structure arrangement surface. Specifically, as shown in FIG. 11, the angle (θ) of the inner wall of the bearing space is inclined by 30 to 45 degrees with respect to the surface when the joystick structure of the present embodiment is arranged in the joystick device. That's it.

    ≪Bearing space inner wall material and joystick shaft contact area material≫

  Further, the inner wall material of the bearing space and the contact region material of the joystick shaft may be configured by a combination of POM (polyacetal) and PA6 (nylon 6). By this combination, friction between the inner wall of the bearing space and the contact area of the joystick shaft can be further reduced. Thereby, the lightness of the stick operation can be achieved and wear due to friction can be reduced.

  <Embodiment 2: Effect>

  The joystick structure according to the present embodiment makes it possible to eliminate rattling of the joystick shaft and reduce wear due to friction between the inner wall of the bearing space of the bearing and the contact area of the joystick shaft.
