Is a cross-sectional view showing a state of coupling with the lower frame. In the figure, (1) is the upper frame, (2) is the first interlocking member, and as shown in FIG. 4, the whole is circumferential, and in the center is a long hole through which the operation shaft 3 is inserted. (4) A hole 6 through which the pin 5 is inserted is formed on the side, and holes 9 for inserting and fixing the rotary shaft 8 of the variable resistor 7 as a rotary detector are provided at both ends. have.

The operating shaft 3 has a plate-shaped cross section, and has a disc, that is, an operating body 10 at the lower end thereof, and a gap with the flat surface at a symmetrical position with respect to the flat surface of the shaft 3. The resulting semi-circular plate-like second interlocking member 11 is provided integrally.

Moreover, the steering wheel 12 which is a handle is fixed to the upper end of the operation shaft 3. The small hole 14 which penetrates is provided in the flat surface of the said 2nd interlocking member 11 and the operation shaft 3, The said pin 5 is inserted in this small hole 14. As shown in FIG. This pin 5 is for fixing the operation shaft 3 and the first interlocking member 2 freely with swinging freedom.

In Fig. 3, reference numeral 16 denotes a return member, and a cylindrical portion 18 for receiving the return spring 17 is formed on the rear surface. 19 is a lower frame, and a concave portion 20 for receiving the return member 16 is formed on an upper surface thereof, and a cylindrical portion 18 of the return member 16 is formed at the center of the concave portion 20. The hole 21 for accommodating sliding freely is provided.

The return spring 17 is accommodated in the cylindrical portion 18 of the return member 16 and the lower end abuts on the bottom surface of the hole 21 of the lower frame 19. The lower frame 19 and the upper frame 1 are coupled to each other by means of a snuff stop 22.

In addition, the second interlocking member 11 is engaged with the rotating shaft of each variable resistor not shown.

Next, the operation of the multidirectional input device described above will be described.

First, when the operator operates the adjustment section 12 in an arbitrary direction, the operation shaft 3 swings the intersection point of the axial center of the first interlocking member 2 and the pin 5 to the point. Then, the first interlocking member 2 and the second interlocking member 11 and the like rotate in response to the swing of the operating shaft 3, and the respective shafts 8 of the variable resistor 7 rotate again to form a resistance value. Is adjusted.

When the steering wheel 12 is not operated, the return member 16 is pushed upward by the return spring 7 so that the upper surface of the return member 16 is pushed upward of the lower surface of the operating body 10 in the vertical direction. 12 is stored in the hole of the upper frame 1 as shown in FIG. 3A.

As shown in FIG. 3B, when the steering wheel 12 is tilted by the operation, the operating body 10 rotates with the rotational center as a point, and a part of the periphery of the operating body 10 returns to the return member 16. Move the upper surface of contact. Accordingly, the return member 16 moves downward in parallel, so that the return spring 17 compresses and exerts a force. When the operating force is released, the steering wheel 12 returns to the neutral state in FIG. 3A by applying this force.

However, in order to move the cylindrical portion 18 of the return member 16 smoothly in the hole 21 of the lower frame 19 when operating the steering wheel 12 or upon return, the cylindrical portion 18 A clearance C as shown in FIG. 5 is provided between the outer circumference of the cylinder and the inner circumferential surface of the hole 21, but the outer length of the cylindrical portion 18 is relatively large. There is a problem that the deviation of the generated length tends to be large, and therefore, the clearance becomes larger than necessary and the shaking occurs during the operation of the steering wheel 12 or in the box.

The present invention is intended to solve the above problems, and an object of the present invention is to provide a multi-directional input device for preventing the shaking between the operation during operation or return between the operation.

In order to solve the above problems, the present invention attaches at least one set of rotary detectors to the orthogonal side surfaces of the frame, and one end of the rotary shaft of the rotary detector is rotatably attached to one another in the frame. Article 1. The first and second interlocking members are engaged with the operation shafts which are engaged with the end portions of the second interlocking members and protrude from the holes provided on the upper surface of the frame, and the operation axes are rotated in an arbitrary direction. And a plate-shaped operating body provided at the end of the operating shaft through the second interlocking member so that the angular rotary detector can be adjusted at the same time, and the end of the operating shaft in the hole of the shaft protruding from the inner bottom of the operating body. The spring for automatic return of the said operation shaft is provided between the spring receiving part provided in a part of the said operation shaft, and the inner bottom face of the said operation body so that it may move so that it may move in the longitudinal direction of this operation shaft.

In the present invention, when the operating shaft is not in operation, the inner bottom of the operating body is suppressed by a spring for automatic return, and the end of the operating shaft is fused to the hole in the number of axes of the operating body. In this state, when the operating shaft is operated in an arbitrary direction, the operating shaft swings in the same direction along the number of axes of the operating body, the operating body is inclined, and a part of the periphery of the operating body is disposed below the member, for example, the lower frame. Move the contact point.

As a result, the lower frame raises a part of the outer periphery of the operating body toward the upward direction of the operating axis against the spring elasticity of the automatic return, so that the operating body also rises along the leading end of the operating shaft.

In the meantime, the rotational detector is adjusted through the first and second interlocking members. Then, when the operating force of the operating shaft is removed, the operating body is pressed downward by the restoring force of the spring, a part of the periphery of the operating body is slid along the lower frame, and the operating body gradually shifts to the performing state with respect to the lower frame, and soon Return to inoperative state.

As described above, the end of the operation shaft moves up and down in the hole of the axis number of the operating body when the operation axis is actuated and when it is returned. By forming between the holes, the clearance can be made to the minimum necessary, so that no shaking occurs when the operation shaft is operated or returned.

In addition, the return member can be omitted as compared with the conventional example described above.

EMBODIMENT OF THE INVENTION Hereinafter, the Example of this invention is described based on an accompanying drawing.

1 and 2 are explanatory diagrams of embodiments of the present invention, and FIG. 1 is an exploded perspective view of a multidirectional input device, and FIG. 2A and FIG. 2B are cross-sectional views for explaining the operation. In FIG. 30, the upper frame 31 is an arch-shaped first communication member, and holes 34 for inserting and fixing the rotating shaft 33 of the variable resistor 32, which are rotary detectors, at the bent portions at both ends thereof. This is installed, the long groove 35 is provided in the long direction.

Reference numeral 36 is an operation shaft, and the lower end 36a is fused to the hole 50 of the shaft 37a of the dish-shaped operating body 37 formed by a mold or the like, and a disc 38 is provided at the center portion thereof. have.

A circular recess 37b is provided in the center of the bottom of the operating body 37.

The disc 38 is provided with a small hole 39 penetrating therethrough, and a steering wheel 55, which is a handle, is fixed to the upper end of the operation shaft 36.

40 is a second interlocking member having a sphere 41 in the center and an arm 42 on the left and right sides of the sphere 41, and at the tip of each arm 42 is a variable detector. The hole 43 to which the rotating shaft 33 of the resistor 32 couples is provided.

In addition, an elongated groove 45 penetrates the lower surface of the upper surface of the sphere 41.

The operating shaft 36 and the disc 38 are inserted into the long groove 45 of the second interlocking member 40 and the operating shaft 36 is inserted into the long groove 35 of the first interlocking member 31. After aligning the hole 39 of the disc 38 and the sphere 41 of the second interlocking member 40 with the hole 44 of the side portion, the pin 46 is inserted into the operation shaft 36. And the first interlocking member 31 are swingably attached.

The first and second interlocking members 31 and 40 assembled in this way are housed therein at the bottom of the upper frame 30 to lock the variable resistor 32 to the upper frame 30, The rotary shaft 33 of the variable resistor 32 is inserted into one hole 34 of the first interlocking member 31 so as to be inserted into one end 34 of the second interlocking member 40. 33) is inserted and locked into the hole 43 in the attachment portion. Reference numeral 47 is a spring support formed integrally with the operation shaft 36 in the lower portion of the disc 38 of the operation shaft 36, the operation between the spring support 47 and the inner bottom surface of the operating body 37. The tangential spring 48 for a return is elastically installed in the non-operation position of the shaft 36. As shown in FIG.

The multidirectional input device of the present invention has the above configuration, and its operation will be described next. When the operator operates the steering wheel 55 in an arbitrary direction, the steering wheel 55 swings with the intersection point 0 of the axial center of the second interlocking member 40 and the pin 46 as a point. The first interlocking member 31 and the second interlocking member 40 are rotated in accordance with the swing of the operation shaft 36, and the respective rotation shafts 33 of the variable resistor 32 are rotated to adjust the resistance value. Is done. Next, the automatic return operation of the steering wheel 55 will be described. When the steering wheel 55 is not in operation, as shown in FIG. 2A, the steering wheel 55 is upright in the hole 56 of the upper frame 30, and the operating body 37 is connected by the tangential spring 48. It is elastically connected to the lower frame 49, and the edge part 36a of the operation shaft 36 is fused to the hole 50 of the number of axes 37a of the operation body 37.

In this state, when the steering wheel 55 is pressed clockwise as shown in FIG. 2A, the operation shaft 36 is inclined in the same direction along the axis 37a of the operation body 37, A part of the periphery abuts the bottom of the lower frame 49. As a result, the bottom surface of the lower frame 49 presses a part of the outer circumferential surface of the operating body 37 while pressing the tangential spring 48 upwards in the longitudinal direction of the operating shaft 36, thereby storing the operating body 37. It moves upwardly inclined along the front-end | tip 36a of the operating shaft 36 which fuses to 37a.

Then, if the pressing force in the same direction of the steering wheel 55 is removed, the operating body 37 is driven by the restoring force of the tangential spring 48 to the end portion 36a of the operating shaft 36 hydraulically acting on the shaft 37a. Therefore, it is pressed downward and inclined, and a part of the periphery of the operating body 37 comes into contact with the bottom of the lower frame 49, and the operating body 37 gradually moves horizontally with respect to the bottom of the lower frame 49. Then, the process returns to the non-operation state shown in FIG. 2B.

Further, the bottom periphery of the operating body 37 in contact with the bottom surface of the lower frame 49 is the rotational (swinging) center 0 of the operating shaft 36 and the lower frame of the operating body 37 in an inoperative state ( 49), it is a half-moon-shaped portion with a large radius of curvature or a half-moon-shaped portion with a radius of curvature in a direction facing outwards by a radius connecting the outer circumference or the like that contacts the outer periphery.

As a result, when the operating shaft 36 is knocked down, the operating body 37 is placed at a position where the bottom outer periphery of the sculpture 37 does not deviate greatly from the point of contact with the lower frame 49 in a neutral state (FIG. 2A). By applying a force to the half-moon-shaped portion of the bottom circumference of the bottom), a large moment for the return of the operating body 37 is obtained, regardless of the falling angle of the operating shaft, so that the longitudinal operation and the return operation of the operating shaft 36 It is done flat.

The multidirectional input device of the present invention has the above-described configuration, and when the steering wheel 55 is operated or returned, the end portion 36a of the operating shaft 36 has a hole in the shaft 37a of the operating body 37. Since the upper and lower sides are movable in the 50 and are formed by the end 36a of the operation shaft 36 having a relatively short length and the hole 50 of the shaft 37a, these processing variations It can be suppressed little, and the clearance formed between them can be made into the minimum accordingly, and it can prevent that a shake arises at the time of the operation or return of the control board 55 hereby.

In addition, since there is no need to design a return member (illustrated by (6) in FIG. 4) conventionally required, the number of parts can be reduced as compared with the conventional one.

In the above embodiment, the variable resistor is used as the rotary detector, but the present invention is not limited thereto, and a rotary switch and an encoder may be used, and the number of the detector is preferably about three to four. .

According to the present invention, as described above, it is possible to prevent the occurrence of shaking caused when the operation of the operation shaft or the return occurs, and the structure can be simplified by reducing the parts as compared with the prior art.
