Description

  The present invention relates to a rotation mechanism for an operation panel of OA equipment such as FAX.

  As a conventional operation panel rotation mechanism, an operation panel of an OA device such as a FAX is fixed to the OA device main body, or is rotated by a certain angle and is fixedly held at that angle.

Therefore, since the operation panel of the OA device such as a conventional FAX is a liquid crystal panel, there is a drawback that it is difficult to see depending on the angle.
In particular, because of the fixed type, it was accompanied by physical fatigue for disabled persons using wheelchairs.

  The problem to be solved by the present invention is that the operation panel can be tilted in a state close to an unauthorized floor, and it is easy for the disabled person to use the wheelchair without physical fatigue. An object of the present invention is to provide an operation panel rotating mechanism capable of tilting the operation panel at an angle.

  An operation panel rotation mechanism according to the present invention is provided in an OA device such as a FAX, and in an operation panel rotation mechanism that rotatably mounts the operation panel, a shaft fixed to the OA device and fixed to the shaft. A first click member that is rotatably attached to the operation panel and that fixes and fixes the operation panel; a crown tooth that is formed on the first click member and that is concentric with the axis of the shaft; and the first click member A second click member mounted on the shaft so as to be adjacent to the crown, a crown tooth formed on the second click member and meshing with the first click member, and the second click member as the first click member. The operation panel is composed of pressing means that presses and elastically meshes both crown teeth, and the operation panel is tilted in steps of about several degrees by forming a large number of teeth of the crown teeth. Characterized in that the structure of the paddle Giyaratchi shape. In addition, the holding force of the operation panel can be made variable by adjusting the thrust force of the gear latch by changing the tightening force of a tightening nut that is screwed onto the shaft to tighten the pressing means. Features. Further, the pressing means for applying a pressing force in the thrust direction of the gear latch is constituted by a disc spring, and is miniaturized. Still further, the peak shape of the gear crest is R.

1) By increasing the number of teeth of the crown gear, there is an effect that the operation panel can be tilted in a state close to a stepless floor.
Therefore, for persons with disabilities who use wheelchairs, the operation panel can be tilted at an angle that is easy for the disabled person to use without physical fatigue, and the buttons on the operation panel can be operated. .
2) Further, by adopting a structure in which the number of teeth of the crown gear is increased, the contact area between the crown teeth is increased, and a large holding force can be obtained.
Therefore, it is possible to eliminate the tilt movement even when the operator applies a large load to the panel unexpectedly.
3) Even if a force is applied from the outside to the operation panel tilted at a certain angle when the tilt is variable, the operation panel can sufficiently hold the angle because of the fine gear latch shape.
4) The peak shape of the gear crest can be changed to an R shape to make the operation sound quieter.

1 and 2, 1 is an operation panel, 2 is a washer, 3 is a first click member, 3a is a crown formed on the side surface of the first click member 3, 4 is a second click member, 4a is the A crown tooth formed on the side surface of the second click member 4 and meshing with the crown tooth 3a, 5 is a washer, 6 is a tightening nut, 7 is a small washer, and 8 is a plurality of plates (4 in this embodiment). It is a spring, and the shaft 9 is penetrated on the central axis of these members 2-8. Reference numeral 10 denotes a casing of the OA device.
FIG. 3 is a drawing in which the crest of the crown tooth has an R shape.

The operation panel rotating mechanism of the present invention is provided in a tilt mechanism having a pressing means for applying a pressing force in the thrust direction of the shaft 9, and meshes with the second click member 4 having the crown 4a and the crown 4a. In the first click member 3 having the crown tooth 3a and the crown teeth 3a and 4a of the two click members 3 and 4, the centers of the concentric circles of the crown teeth 3a and 4a are penetrated, and the two click members A shaft 9 is provided so that the crown teeth 3a and 4a of the 3 and 4 mesh with each other.

The four disc springs 8 are specific examples of the pressing means of the present invention and have a function of generating a pressing force. Four disc springs 8 push the crown tooth 4a in the direction of the other crown tooth 3a. This pressing force works so as not to rotate the crown teeth 3a, 4a and by extension both the click members 3, 4 and suppresses the rotational torque. A force acts in the direction of rotating (tilting) the operation panel 1 from the outside, and the operation panel 1 is rotated only when the force is greater than the thrust force.

Conventionally, it has been common to use a winding spring to apply the thrust load. Conventionally, a latch structure with a large step is used to secure the holding force, and a considerable force is required for the user to perform the tilting operation.
The present invention is light and compact by using the disc spring 8 as the pressing means of the tilt mechanism, and is more practical in terms of cost and structure. Further, the thrust load can be adjusted by turning the tightening nut 6 while adjusting it.

By making the crown teeth 3a and 4a into a gear latch shape, even if the user puts his hand on the operation panel 1 and applies a light force, the tilt angle of the operation panel can be maintained.

  The first click member 3 having the crown 3a is attached and fixed to the operation panel 1, and the operation panel 1 is rotated by the rotation of the first click member 3 around the shaft 9.

The casing 10 has a shaft 9 attached and fixed, and the shaft 9 is prevented from rotating in the circumferential direction of the center of rotation.
The washer 5 is in contact with the second click member 4 and is also in contact with the disc spring at the left end of the four disc springs 8. As a result, the washer 5 propagates the large thrust force of the four disc springs 8 to the second click member 4 in contact with the washer 5.

The rotational torque of the crown teeth 3a, 4a is also suppressed by the friction generated in the washer 2 and the first click member 3. Further, the friction between the washers 2 and 5 and the click members 3 and 4 and the force in the large thrust direction of the disc spring 8 prevent the click members 2 and 4 from rotating around the shaft 9. .

It is an external view of the operation panel of OA equipments such as FAX and the rotation mechanism for the operation panel of the present invention. It is a disassembled perspective view of the rotation mechanism for operation panels of this invention. It is drawing which made the peak point of the crown tooth into R shape.
