Abstract

PURPOSE:To securely fix and support a moving section of an operation display section, etc., on which external force or their own weights act to a main body part at a desired angle. CONSTITUTION:A main body side joining body 4 having a regular hexagonal shape and a spring 5 are inserted and fitted into a recess 11 of a regular hexagonal shape formed in the main body part 1. An operating display part side joining body 6 is disposed to face this main body side joining body 4. A shaft 9 provided with external screw threads 8 at one end, a knob 7 at the other end and a flange 10 in the middle, respectively, is loosely fitted into the main body side joining body 4 and the operating display part side joining body 6. The plural meshing grooves 3 of the main body side joining body 4 and the plural meshing grooves 3 of the operating display part side joining body 6 are joined by the flange 10 of the shaft 9 which overcomes the force of the spring 5 by screwing the external screw threads 8 of the shafts 9 into the internal screw threads 13 formed in the main body part 1. The flange 10 of the shaft 10 moves rightward and the pressurized contact force of both joining bodies is weakened when the knob 7 is rotated in one direction and, therefore, the angle of inclination of the operation display part 2 relative to the main body part 1 is arbitrarily adjusted.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a satellite communication device equipped with a device having a movable part such as an operation display part (for example, a push button switch and a liquid crystal display) and the like. The present invention relates to a tilt mechanism that can be securely fixed and supported by inclining at a desired angle.

[0002]

2. Description of the Related Art Conventionally, in a personal computer or the like, for example, as shown in FIG. 2, a main body portion a and a display portion b are formed, and the display portion b is opened to the main body portion a side at the time of use. On the other hand, a tilt mechanism has been developed between the main body part a and the display part b in order to tilt it at a desired angle.

As this tilt mechanism, for example, as shown in FIG. 3, a rotating plate f having a hole or a recess e formed therein is fixed to a rotary shaft d at a side end of a side surface of a display part b, and A hole e is provided at a facing portion of the main body (not shown) through a spring g.
There is one having a so-called ball ratchet structure in which a ball h that fits into the above is attached. Further, in addition to the above-mentioned tilt mechanism, as shown in FIG. 4, for example, a joined body in which a plurality of engaging grooves i are engraved in portions of the main body portion and the display portion (not shown) facing each other. It is also known to have j and to bring the joined body j on one side thereof into pressure contact with the joined body j on the other side via a spring k.

In the case of a tilt mechanism having a large display unit weight, as shown in FIG. 2, a balance weight c having a constant mass is provided on the base end face separated from the rotary shaft on the side surface of the casing of the display unit b by a predetermined distance. Generate a moment that exactly cancels the moment due to gravity around the rotation axis,
Even a display unit having a large mass can be securely fixed and supported while the display unit is surely tilted.

[0005]

However, in these types of tilting mechanism, the weight of the display portion is supported by the elastic force and frictional force of the spring and the balance weight. There is an operation section on the display,
When an external force acts, it may not be able to withstand the external force. Also, in terms of the weight of the device, when the balance weight is added, the weight itself becomes large, which causes a weight increase.

In view of the above-mentioned drawbacks of the prior art, the present invention allows a movable portion such as an operation display portion, which is acted upon by an external force or its own weight, to be firmly fixed and supported to the main body portion at a desired angle. It is an object to provide a mechanism.

[0007]

In order to solve the above-mentioned problems, the present invention joins a non-circular recess such as a polygon or an ellipse provided in the main body with a non-circular shape on the main body side. Insert the body and spring and mate them, make the movable body side joint body such as the operation display unit face the main body side joint body, screw on one end, knob on the other end, shaft with flange in the middle. , The main body side joint body and the movable body side joint body are loosely engaged, and the male thread of the shaft is provided in the main body part, so that the shaft flange resists the spring and the main body side joint body and the movable body side joint are screwed into the screw. A tilt mechanism for joining the body and the body is joined, and an engaging groove, a ball ratchet structure, a friction plate, or the like is adopted for the body-side joined body and the movable body-side joined body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a tilt mechanism of an operation display section of a satellite communication device according to the present invention. This tilt mechanism includes a main body 1 provided with a regular hexagonal recess 11 and a female screw 12, an operation display unit provided with an operation display unit side joined body 6 having a plurality of engagement grooves 3 (for example, a push button switch and (Liquid crystal display) 2, main body-side joined body 4 having a regular hexagonal outer shape having a plurality of engaging grooves 3, a spring 5, and a knob 7 fixed to one end, a screw 8 cut on the other end, and a flange in the middle. The shaft 9 is provided with 10 respectively.

The assembly sequence will be described. First, the spring 5 and the regular 6-shaped main body side joined body 4 are inserted into and fitted into the regular hexagonal recess 11 of the main body 1, and then the operation display portion side joined body 6 is inserted into the plurality of engaging grooves 3. And the plurality of engagement grooves 3 of the regular hexagonal main body-side joined body 4 are joined together, and then the shaft 9 is loosely fitted to the regular hexagonal main body-side joined body 4 and the operation display section-side joined body 6. , Screw the male screw 8 into the female screw 12 of the main body 1,
When the flange 10 comes into contact with the operation display unit side joined body 6, the assembly is completed.

In order to adjust the tilt angle of the operation display section 2 with respect to the main body section 1, when the knob 7 is rotated in one direction,
Since the flange 10 of the shaft 9 moves to the right in FIG. 1A, the plurality of meshing grooves 3 of the regular hexagonal body-side joined body 4 and the plurality of meshing grooves of the operation display portion-side joined body 6 by the spring 5 are formed. Since the pressure contact force with 3 is weakened, the tilt angle of the operation display unit 2 with respect to the main body unit 1 can be arbitrarily adjusted.
After the adjustment, when the knob 7 is rotated in the opposite direction to the above, the flange 10 of the shaft 9 moves to the left in FIG. Since the pressure contact force between the plurality of engagement grooves 3 and the plurality of engagement grooves 3 of the operation display unit side joined body 6 is strengthened, unnecessary change in inclination of the operation display unit 2 caused by external force such as a push button switch or its own weight is prevented. Therefore, the operation display unit 2 can be firmly fixed and supported to the main body unit 1 at a desired angle.

In this embodiment, the regular hexagonal main body side joint body 4 and the operation display portion side joint body 6 adopt a type of interlocking structure of a plurality of interlocking grooves 3. The design can be changed to be modified into a ball ratchet structure type or a structure type using friction plates or the like that are in pressure contact with each other (the stepless tilting of the operation display unit is possible).

[0013]

As described above, according to the tilt mechanism of the present invention, it is possible to prevent unnecessary change of the tilt angle of the movable portion such as the operation display portion due to the external force of the push button switch or the own weight, The movable portion can be firmly fixed and supported to the main body portion at a desired angle.

According to the tilt mechanism of the present invention,
Since it has a simple structure, it can be applied to many types of tilt mechanisms, and is extremely practical in terms of reducing the size and weight of the device and reducing manufacturing costs.
