Description

  The present invention relates to a joystick, and more particularly, to a small-sized joystick that prevents damage to the pivot portion of a rotating member of the joystick and improves the feel of a rotating operation.

  Conventionally, as shown in FIG. 9, the upper case cover 1 and the lower case cover 2 face each other and are disposed in a case cover main body 3 formed in one general box shape so as to be orthogonal to each other and rotatable. A pair of upper and lower rotating members 4, 5 and long holes 6, 7 opened in the longitudinal direction of each rotating member 4, 5, and one end portion is extended to the outside of the case cover body 3. Provided with an operating member 8 and a spring (not shown) for biasing the pair of rotating members 4 and 5 to hold them in a neutral position, and a signal corresponding to the rotation angle of each rotating member 4 and 5 A joystick 9 having a set of signal output means (not shown) for outputting is known (see, for example, Patent Document 1).

In the joystick described in Patent Document 1, the upper case cover 1 is made of metal, and the lower case cover 2 is made of a resin material. As shown in FIG. 10, the rotary pivots 4 a and 5 a that become the axes when the rotary members 4 and 5 rotate are sandwiched between the bearing portion 1 a of the upper case cover 1 and the bearing portion 2 a of the lower case cover 2. The case cover body 3 is rotatably held.
JP2003-223276A.

  In the conventional small-sized joystick, the metal upper case cover 1 that is in contact with the rotary pivot shafts 4a and 5a is formed by press working, and the fracture surface is used as the bearing portion 1a. There is a possibility of generating burrs on the fracture surface. This burr scratches the outer peripheral surfaces of the rotary pivots 4a and 5a when they rub against the rotary pivots 4a and 5a. In addition, the rough surface caused by the scratch may inhibit the rotation and may make the operation uncomfortable. Furthermore, the outer peripheral surfaces of the rotary pivots 4a and 5a are easily worn, and the life of the rotary pivots 4a and 5a is reduced. For this reason, in order not to generate burrs, management at the time of press working is required, and there is a problem that costs are increased.

  In order to eliminate the occurrence of burrs, it may be possible to form both the upper case cover and the lower case cover with a resin member, but if the upper case cover is not sufficiently formed by applying sufficient fleshing, Problems arise in terms of durability.

  Further, if the entire upper case cover is sufficiently thickened, the shape of the entire upper case cover becomes large, which hinders downsizing. Furthermore, when the joystick is attached to the board, it becomes a structure in which a mounting screw is screwed and fixed to the mounting hole of the lower case cover from the lower side of the board through the mounting hole of this board. The screw is fixed at one point. For this reason, during operation, an excessive force is applied to the screwed portion, which may damage the substrate.

  Therefore, even if the metal upper case cover is used, there is no problem of burrs, miniaturization is possible, and it is strong and excellent in durability, and does not cause excessive force on the substrate during operation. A technical problem to be solved for the structure arises, and the present invention aims to solve this problem.

  The present invention has been proposed in order to achieve the above-mentioned object, and the invention according to claim 1 includes a case cover body formed into one general box shape by abutting the upper case cover and the lower case cover with each other. A pair of upper and lower rotating members disposed in the case cover body so as to be rotatable perpendicularly to each other, and one end passing through a long hole opened in the longitudinal direction of each rotating member. An operation member whose part side extends to the outside of the case cover main body and a spring that biases the pair of rotating members to be held in a neutral position are provided, and the rotation of each rotating member is provided. In a joystick having a set of signal output means for outputting a signal corresponding to an angle, the upper case cover is made of a resin that is substantially overlapped with a metal outer case portion and the outer case portion. Inner case part The lower case cover is formed of a resin member, and the rotating pivot of each rotating member is sandwiched between the inner case portion and the lower case cover so as to be rotatably supported. Provide a joystick.

  According to this configuration, the rotation pivot of the rotating member is sandwiched between the resin inner case portion and the resin lower case cover, and the metal outer case portion is not brought into contact with the rotation pivot portion. Even if the outer case portion is used, the problem of burrs does not occur with respect to the rotation of the rotary pivot. In addition, since the metal outer case portion is used together with the inner case portion, sufficient strength can be obtained, and it is not necessary to increase the thickness of the inner case portion.

  A second aspect of the present invention provides the joystick according to the first aspect, wherein a mounting terminal is provided on the lower end portion side of the outer case portion and extends downward from the lower end portion.

  According to this configuration, it is possible to stably attach the joystick to the substrate using the attachment terminals of the outer case portion made of metal.

  A third aspect of the present invention provides the joystick according to the first or second aspect, wherein the color of at least one of the inner case portion and the lower case cover is changed according to the type of the spring.

  According to this configuration, the inner case part and / or the lower case cover are color-coded according to the type of the spring, so just look at the color of the inner case part or the lower case cover. Thus, it is possible to easily identify the type of spring, for example, the type of hardness.

  According to the first aspect of the present invention, even though the metal case portion is used, it is possible to eliminate the influence of scratches caused by burrs on the rotation of the rotary pivot, so that a smooth rotation operation can be obtained. In addition, since the product is not damaged, the service life of the product is longer than before. Moreover, since a metal outer case part is used together with the inner case part, sufficient strength can be obtained. Therefore, it is not necessary to increase the fleshing of the inner case part, so that the size can be reduced. Furthermore, the joystick can be securely attached to the substrate using a part of the metal outer case.

  According to the second aspect of the invention, since the attachment terminal of the outer case portion made of metal is used, in addition to the effect of the first aspect of the invention, the joystick can be securely attached to the substrate.

According to the third aspect of the present invention, the type of spring hardness and the like can be easily identified simply by looking at the color of the inner case portion or the lower case cover. In addition, it is possible to expect a special effect that a desired joystick corresponding to the application can be reliably and easily assembled to the substrate.

Hereinafter, the joystick of the present invention will be described with reference to preferred embodiments.
The basic configuration of the present invention is that a pair of upper and lower rotating members (cranks) arranged orthogonal to each other in a metal case are sandwiched between upper and lower divided resin cases, thereby rotating the rotating members. It is intended to prevent wear of the steel. That is, by providing a resin case between the metal case and the upper rotating member, direct rubbing between the metal case and the rotating member is eliminated.

  In addition, when only the sliding surfaces of the metal case and the rotating member are individually formed with ring-shaped resin parts, the assembly work becomes complicated, but the four sliding surface parts are shared by one resin part. In this case, the structure is simplified and the productivity is improved.

  Even if the upper case cover made of metal is used, there is no problem with burrs, it can be downsized, it is strong and durable, and an unreasonable force is generated on the board during operation. In order to achieve the objective of not having a structure, the upper case cover and the lower case cover are brought into contact with each other to have a case cover main body formed in a substantially box shape, and the case cover main body is orthogonal to each other. And a pair of upper and lower rotating members arranged to be rotatable and a long hole opened in the longitudinal direction of each rotating member, and one end portion is extended to the outside of the case cover main body. And a set of signal outputs for outputting a signal corresponding to the rotation angle of each of the rotating members, and a spring for biasing the pair of rotating members to be held in a neutral position. Joystick with means The upper case cover is formed of a metal outer case portion and a resin inner case portion fitted in the outer case portion and arranged in a substantially superposed manner, and the lower case cover is made of a resin member. And the rotation pivot of each of the rotating members is sandwiched between the inner case portion and the lower case cover and is supported rotatably.

  1 to 5 show a joystick according to one embodiment of the present invention. 6 to 8 show the detailed structure. 1 to 5, reference numeral 20 denotes a joystick. The joystick 20 has a substantially square case cover body 21 in which a lower case cover 21a and an upper case cover 21b are brought into contact with each other and combined into one.

  The lower case cover 21a is made of resin. In the lower case cover 21a, an upper arm (crank) 22 as an upper rotating member orthogonal to each other and a lower arm (crank) 23 as a lower rotating member are provided. Are arranged so as to be pivotable up and down.

  The upper case cover 21b is formed by a metal outer case portion 18a made by press working, and a resin inner case portion 18b that is fitted into the case portion 18a and arranged approximately in a superposed manner. . The mounting terminals 17, 17... Are integrally provided at the four corners of the lower end portion of the outer case portion 18a so as to extend straight downward. On the other hand, the inner case portion 18b is provided with a pair of left and right and front and rear bearing portions 41, 41... At positions that do not overlap the outer case portion 18a. When the joystick 20 is attached to a substrate (not shown), the attachment terminals 17, 17... Are inserted into attachment holes provided in the substrate, thereby fixing the joystick 20 to the substrate.

The upper arm 22 and the lower arm 23 are respectively provided with bearing portions 42, 42,... In which rotational pivots 22 a, 22 a, 23 a, 23 a at both ends are provided on the lower case cover 21 a, respectively. And the bearing portions 41, 41... Of the inner case portion 18b are sandwiched from both sides in the vertical direction and are rotatably supported by the case cover main body 21. That is, the rotary pivot portions 22a, 22a, 23a, 23a are pivotally supported by the resin bearing portions 41, 42 so as to be rotatable. In addition, variable resistors 24 and 25 are respectively connected to one of the rotating pivots 22a and 23a of the upper arm 22 and the lower arm 23 (see FIGS. 3 to 5).

  In addition, elongated holes 26 and 27 extending in the axial direction are opened in the central portions of the upper arm 22 and the lower arm 23, and an operation stick 28 is provided through the elongated holes 26 and 27. . And the lower end part of this operation stick 28 is formed in the convex spherical surface part 28a. On the other hand, a concave spherical surface portion 21d is formed in the upper central portion of the base 21c of the joystick 20, and the convex spherical surface portion 28a is swingably mounted on the concave spherical surface portion 21d. An operation knob (not shown) is fitted to the upper end of the operation stick 28.

  Therefore, when the operation stick 28 is operated in the joystick 20, the operation stick 28 rotates with the concave spherical surface portion 21d as a rotation fulcrum. As a result, the upper arm 22 and the lower arm 23 are rotated. As a result, the variable resistors 24 and 25 connected to the upper arm 22 and the lower arm 23 rotate, and the variable resistors 24 and 25 generate an output corresponding to the operation of the operation stick 28.

  Further, in order to hold the upper arm 22 and the lower arm 23 in the neutral positions, respectively, a ring-shaped support member 29 that is in contact with the base portion 21c of the lower case cover 21a and the lower surface of the lower arm 23. The coil spring 30 is interposed between the two. That is, when the coil spring 30 elastically presses the lower arm 23 upward, the upper arm 22 and the lower arm 23 are held in the neutral position.

  Further, as shown in FIGS. 2 and 4 to 6, the operation stick 28 is provided with shaft portions 31, 31 projecting left and right at the lower portion of the operation stick 28.

  On the other hand, as shown in FIGS. 2 to 6, the lower arm 23 includes left and right side wall portions 23 a and 23 a of the long hole 27, and the lower surface of the central portion of the side wall portions 23 a and 23 a has a substantially semicircular shape. The support portions 32, 32 are provided in a notch. The support portions 32 and 32 are provided in a form in which the lower surfaces are opened on the side wall portions 23 b and 23 b of the lower arm 23. In addition, the support portions 32 and 32 are formed in a size that fits loosely in correspondence with the shaft portions 31 and 31 provided on the operation stick 28. Further, the left and right shaft portions 31, 31 have different left and right sizes, and the corresponding support portions 32, 32 are also formed with different sizes.

  In this case, when the shaft portions 31 are inserted into the left and right sides of the support portions 32 and 32 from the lower surfaces of the support portions 32 and 32, the shaft portion of the operation stick 28 may be loosely fitted in the wrong direction. 31 and 31 cannot be fitted to the support portions 32 and 32. For this reason, there is no possibility that the mounting direction of the operation stick 28 is wrong.

  Further, since the shaft portions 31, 31 are loosely inserted from the lower surfaces of the corresponding support portions 32, 32, the mutual fitting is easily performed. The shaft portions 31 and 31 are prevented from moving upward by the support portions 32 and 32. Therefore, the operation stick 28 is also used as a retaining member, and the shaft portions 31 and 31 are fitted to the lower arm 23 and rotated. In addition, the shaft portions 31, 31 coincide with the respective axes of the upper arm 22 and the lower arm 23 which are upper and lower rotating members. The operation stick 28 is prevented from being pushed in by a concave spherical surface portion 21d provided on the base portion 21c.

Therefore, according to the joystick 20 of this embodiment, the rotary pivots 22a, 23a of the upper and lower arms 22, 23 are connected to the bearing portion 41 of the resin inner case 18b and the bearing portion 42 of the resin lower case cover 21a. The metal outer case portion 18a is not brought into contact with the rotary pivots 22a and 23a. For this reason, even if the metal outer case 18a is used, the problem of burrs does not occur with respect to the rotation of the rotary pivots 22a and 23a.

  As a result, even though the upper case cover made of metal is used, it is possible to eliminate the effect of scratches caused by burrs on the rotation of the rotary pivots 22a and 23a, and smooth rotation operation becomes possible. Also, since it is not scratched, the service life is improved. In addition, since the metal outer case portion 18a is used by being overlapped with the inner case portion 18b, sufficient strength can be obtained, and the inner case portion 18b can be downsized without having to increase the thickness of the inner case portion 18b. become. Furthermore, the joystick 20 can be securely attached to the substrate (not shown) using the attachment terminal 17 which is a part of the metal outer case portion 18a.

  In the present invention, for example, even when the joystick 20 is rotated with a strong force in the operation of a game machine or the like, there is no sliding surface with the metal fracture surface as in the prior art, and contact is made between the resin members. Can be rotated. Further, since the cover case portion is made of metal, the plate thickness can be made thinner than that of resin.

  It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.

  For example, when the coil spring 30 having a different spring force is used, the operation feeling of the operation stick 28 is different, but the inner case portion 18b or the lower case cover 21a is formed depending on the strength of the spring force of the built-in coil spring 30. The color of the resin surface can be changed to, for example, red, yellow, blue or green. In this way, the operator can easily determine at a glance which type or type of coil spring 30 is used from the type of color on the resin surface. Thereby, it is possible to reliably eliminate an erroneous operation of assembling the joysticks 20 of different types.
