Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a two-stage tilt hinge for an OA device, which is suitable for opening and closing the display body in two stages.

[0002]

[Prior Art]

 The applicant made the bearing plate of the mounting member, which is mounted on the main body of the device in the previous application, support the rotary shaft which also functions as the support member of the display body, and fixedly fixed the rotary shaft between the rotary shaft and the bearing plate. We proposed a tilt hinge that was equipped with friction means consisting of various washers so that it would rotate only when the rotational torque was applied.

[0003]

[Problems to be solved by the device]

 Demand for the above-mentioned tilt hinge is rapidly expanding, especially for laptop type OA devices. However, in addition to keyboard input, handwriting input to the display body can be performed in the AV notebook of SE products of OA devices. There is a function that can be performed, and such a tilt hinge for opening and closing the display body is required to be able to open and close the display body in two steps for keyboard input and handwriting input. It became so.

An object of the present invention is to provide a two-step tilt hinge for an OA device, which can open and close the display body in two steps of an opening angle for normal keyboard input and an opening angle for handwriting input. There is

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention relates to a mounting member, a supporting member for rotatably mounted on the mounting member via a rotation shaft, and a supporting member for supporting a display member at a predetermined opening angle of the display member. A ridge provided for contacting the back of the display body or the support member, a friction means for controlling the rotation of the support member provided on the rotary shaft, and one end fixed to the mounting member, and the device main body side It is composed of an elevating rod slidably attached to and an elastic means for urging the elevating rod in one direction.

At this time, the friction means may be composed of a slider washer interposed between one side surface of the mounting member and the flange portion, a spring washer disposed on the other side surface of the mounting member, and a flat washer. It is possible.

Further, the elastic means is constituted by a coiled spring, and its end portion can act to push down the lifting rod downward.

[0008]

[Action]

 When the display body is opened, the support member rotates together with the rotating shaft with respect to the mounting member, and the friction means opens the stop member so that it can be stopped and held at an arbitrary opening angle. It is possible to perform keyboard input while. When it is opened to a predetermined opening angle, the back of the display body or the supporting member comes into contact with the raised portion and stops there once. The opening angle in this state is 123 °. When the display body is pushed open further for handwriting input, a lifting force is generated on the side of the mounting member with the abutting part as a fulcrum, and the lifting rod rises against the elastic force of the elastic means and the display body moves. As a result of allowing further opening, the display body is opened to a substantially horizontal position.

When closing the display body that has been opened to a substantially horizontal position, the lifting rod is returned to the original position as the display body rotates until the back portion of the display body comes into contact with the raised portion, and then only the display body is closed. Is rotated and closed.

【Example】

 The drawings show an embodiment of the present invention, in which reference numeral 1 is a mounting member, and a supporting member 3 is rotatably mounted on the mounting member 1 via a rotary shaft 2, and a display member 4 is mounted on the supporting member 3. Is attached at one end thereof. The rotary shaft 2 is provided with a flange portion 2a, and a slider washer 5 is inserted between the flange portion 2a and one side surface of the mounting member 1 while inserting the rotary shaft 2 into the insertion hole 5a. On the other side of the mounting member 1, the spring washer 6 and the flat press washer 7 are attached in this order while inserting the rotary shaft 2 into the through holes 1a, 6a, 7a respectively provided therein. By caulking one end of the shaft 2, the washers are brought into pressure contact with each other to form the friction means 13.

A hollow portion 8 a and a raised portion 8 b are provided on the apparatus main body 8 side, and a cylinder portion 9 is suspended in the hollow portion 8 a, and a lifting rod 10 is slidably mounted on the cylinder portion 9. It has been received. The mounting member 1 is fixed to the upper part of the elevating rod 10 by a screw 11 and the lower end of the mounting member 1 is fixed by a screw 14, and the locking piece 15 protruding in the radial direction has a string winding which is an example of elastic means. One end 12a of the spring 12 is locked, and the lifting and lowering rod 10 is urged so as to always pull it downward.

Further, the friction means 13 can be configured by changing the type and combination of washers other than the embodiment. For example, a thrust washer made of phosphor bronze is interposed between the spring washer and the mounting member to prevent abrasion.

The elastic means may be replaced by a leaf spring in place of the string winding spring, or a compression coil spring wound around the elevating rod 10 in a circular manner or other known means.

[0014]

[Effect of the device]

 Since the present invention is configured as described above, the display body of the OA device having two functions of keyboard input and handwriting input with one hinge can be independently provided in two stages for keyboard input and handwriting input. The effect of being able to open and close can be achieved.
