Description

[0001]
[Industrial application fields]
The present invention relates to an angle adjustment device for an electronic device, and more particularly to an angle adjustment device for an electronic device suitable for adjusting an installation angle of an electronic device such as a telephone.
[0002]
[Prior art]
Conventionally, as an apparatus for adjusting the angle of a telephone, those shown in FIGS. 9 and 10 are known.
[0003]
9 and 10, the telephone is configured to include a handset 1, an upper case 2, and a lower case 3, and the lower case 3 is configured as an angle adjustment device for the telephone. That is, the angle adapter 4 is provided on the bottom side of the lower case 3. The angle adapter 4 is formed in a substantially U shape, and both end sides are rotatably connected to a rotating shaft fixing portion 6 having a hinge structure via a rotating shaft 5. Further, a groove 7 is formed in a substantially central portion of the angle adapter 4, and a claw 8 is provided in the lower case 3 corresponding to the groove 7.
[0004]
In the conventional example configured as described above, when connecting the rotating shaft 5 of the angle adapter 4 to the rotating shaft fixing portion 6 of the lower case 3, the spring-like rotating shaft fixing portion 6 is bent in the direction of the arrow. Can be connected. Further, when adjusting the operation surface or display surface of the telephone to an appropriate angle, first, when setting the angle low, the angle adapter 4 is tilted to attach the claw 8 to the groove 7 so that the angle adapter 4 is attached to the lower case 3. Fix it. On the other hand, when the angle is set high, the claw 8 can be removed from the groove 7 and the angle adapter 4 can be rotated around the rotating shaft 5 to be used at the set angle. Examples relating to this type of technology include Japanese Utility Model Laid-Open No. 61-121055 and Japanese Utility Model Laid-Open No. 1-174973.
[0005]
[Problems to be solved by the invention]
However, in the above-described conventional configuration, when adjusting the angle of the operation surface or display surface of the telephone, there are only two choices of rotating the angle adapter 4 around the rotation shaft 5 or raising or lowering it. That is, the angle cannot be set in multiple stages. Even in the case of the prior art, if a stopper is provided in the rotation region of the angle adapter 4, angle adjustment in multiple stages is possible, but such a method cannot be realized in terms of strength.

【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 5, the telephone includes a handset 10 and upper cases 11 and 12, and an angle adapter base 13 is disposed on the bottom side of the lower case 12. The lower case 12 is connected to the bottom side of the upper case 11 and constitutes an angle adjusting device together with the angle adapter base 13. The lower case 12 is configured in a substantially rectangular box shape, and a pair of brackets 14 are arranged opposite to each other at the front portion on the bottom side of the lower case 12, and each bracket has a columnar rotating shaft. 15 is provided. Further, a claw 16 is bulged on the bottom surface side of the lower case 12, and a recess 17 is formed in the vicinity of the claw 16. Three pairs of holes 18a, 18b, 18c are formed in the recess 17 along the front-rear direction. The holes 18a to 18c are formed with claws 19a, 19b, and 19c that form part of the holes and form multi-step inclined surfaces. Further, contact surfaces 20a, 20b, and 20c are formed around the holes 18a to 18c. A protrusion 22 on the distal end side of the angle adapter 21 that is rotatably connected to the angle adapter base 13 is inserted into the holes 18a to 18c. That is, as shown in FIG. 6, the angle between the lower case 12 and the angle adapter base 13 can be adjusted in three stages by selecting and inserting any one of the holes 18 a to 18 c into the protrusion 22 of the angle adapter 21. It is like that.
[0014]
On the other hand, the angle adapter base 13 is formed in a substantially box shape corresponding to the lower case 12, and a rotation shaft fixing portion 23 that rotatably supports the rotation shaft 15 is provided on the front side of the angle adapter base 13. Yes. The rotating shaft fixing portion 23 has a hinge structure, and as shown in FIG. 7, the rotating shaft 15 of the lower case 12 is attached by bending the rotating shaft fixing portion 23, and the rotating shaft fixing portion 23 lowers the lower case. The front side of 12 is rotatably supported via a rotating shaft 15. A hole 24 as a recess is formed in a substantially central portion of the angle adapter 13, and a claw 25 that engages with the claw 16 of the lower case 12 is bulged at the front end of the hole 24. Further, a pair of rotating shaft fixing portions 26 are formed at the rear end portion of the hole 24. A groove 27 is formed in each rotating shaft fixing portion 26. A region between the groove 27 and the groove 27 is formed as a rotation region of the angle adapter 21, and a pair of leaf springs for pressing the angle adapter 21 are disposed in this region. A rotating shaft 29 formed in the angle adapter 21 is inserted into each groove 27. The rotating shaft 29 has a shape obtained by cutting both sides of a circle. That is, the rotating shaft 29 is formed with a portion whose width is narrower than the diameter of the circle. For this reason, when the angle adapter 21 is rotatably connected to the angle adapter base 13, as shown in FIG. 8, the narrowed portion of the rotary shaft 29 is inserted into the groove 27 and is moved in the direction of the arrow. By rotating along, the rotating shaft 21 can be rotatably mounted on the rotating shaft fixing portion 26. Further, since the pair of ribs 30 are formed to bulge in the angle adapter 21, the ribs 30 come into contact with the leaf springs 28 to prevent the rotation shaft 29 from rotating in the reverse direction. Can be securely attached.
[0015]
Thus, according to the present embodiment, the protrusion 22 on the distal end side of the angle adapter 21 is inserted into any one of the holes 18 a to 18 c of the lower case 12, whereby the lower case 12 and the angle adapter base 13 are separated. The angle can be adjusted in three stages. In this case, since the edge of each hole 18a-18c is supported by the contact surface 31 of the angle adapter 21, the lower case 12 can be supported in an excellent state. Further, when the projection 22 of the angle adapter 21 is removed from the hole and stored in the hole 24, the bulging portion 32 of the angle adapter 21 comes into contact with the bottom surface side of the lower case 12, and the lower case 12 and the angle adapter base 13 are The angle can be set to the minimum angle. That is, in this embodiment, the angle of the lower case 12 and the angle adapter base 13 can be adjusted in four stages.
[0016]
In the above embodiment, the rotating shaft 15 is provided in the lower case 11 and the rotating shaft 29 is provided in the angle adapter 21. However, each rotating shaft may be provided in the angle adapter base.
[0017]
【The invention's effect】
As is apparent from the above embodiments , the present invention constitutes the bottom side of the electronic apparatus, and the front side of the lower case and the front side of the angle adapter base that have a plurality of engagement holes across the bottom surface can be rotated. The angle adapter engagement protrusion provided in the angle adapter base is engaged with the engagement hole provided in the lower case, and the bulge portion of the base end portion of the angle adapter is the angle adapter. When the angle adapter is used, the engaging protrusion of the angle adapter is connected to the engaging hole of the lower case when the angle adapter is used. Engage and incline the electronic device at an arbitrary angle to adjust the angle in a wide range.When not in use, the angle adapter is housed in the recess, but the bulging part contacts the bottom side of the lower case. Keep the electronics at a minimum angle In addition to the number of steps of angle adjustment by engagement of the engagement protrusions of the angle adapter, the bulge portion of the base end portion of the angle adapter can set a further minimum angle without using a new member. The effect of widening the range of angle adjustment is obtained.
