Abstract

A casing angle adjustment mechanism capable of adjusting the angle of a casing with respect to a mounting surface by a simple operation of a leg unit is provided. When an angle adjustment mechanism of a casing rotates a leg unit in one direction, moves a part of a stopper along a connection hole of the leg unit, and slides a slide plate, a side wall of the slide plate blocks openings of engagement holes of the leg unit, and a side wall of the leg unit blocks openings of engagement grooves of the slide plate, and when it rotates the leg unit in another direction, moves the part of the stopper along the connection hole of the leg unit, and slides the slide plate, engagement grooves of the slide plate and engagement holes of the leg unit are placed to overlap.

First claim

The invention claimed is:

1. A casing angle adjustment mechanism comprising:
a slide plate;
a leg unit configured to be rotatably connected to a rear side of a casing and allow the slide plate to be slidably inserted into the leg unit; and
a stopper configured to be rotatably connected to the rear side of the casing, wherein
the slide plate includes a plurality of engagement grooves formed on a surface of the slide plate, and a first protrusion and a second protrusion protruding from the surface of the slide plate and placed so that the plurality of engagement grooves are interposed therebetween,
the leg unit includes a plurality of engagement holes formed on a side wall of the leg unit and corresponding to the plurality of engagement grooves of the slide plate, and a connection hole formed on the side wall of the leg unit so as to connect openings of the plurality of engagement holes,
when, from a state where a part of the stopper is passed through the engagement groove of the slide plate and the engagement hole of the leg unit and an angle of the leg unit with respect to the casing is fixed, rotating the leg unit in one rotating direction relative to the casing, moving the part of the stopper to one side where the leg unit is connected to the casing along the connection hole of the leg unit, and sliding, through the first protrusion, the slide plate to the one side of the leg unit, a side wall of the slide plate blocks the openings of the engagement holes of the leg unit, and the side wall of the leg unit blocks openings of the engagement grooves of the slide plate when viewing the leg unit in a left-right direction, and
when, from a state where the slide plate has slid in one direction, rotating the leg unit in another rotating direction relative to the casing, moving the part of the stopper to another side of the leg unit along the connection hole of the leg unit, and sliding, through the second protrusion, the slide plate to the another side of the leg unit, the plurality of engagement grooves of the slide plate and the plurality of engagement holes of the leg unit are placed to overlap when viewing the leg unit in a left-right direction.

2. The casing angle adjustment mechanism according to claim 1 , wherein the engagement hole of the leg unit includes a latching part to latch the part of the stopper inside the engagement hole of the leg unit.

3. The casing angle adjustment mechanism according to claim 1 , wherein
the stopper is U-shaped, and
both ends on one side having an opening of the stopper being rotatably connected to the rear side of the casing, and another side being the part of the stopper that is passed through and engaged with the engagement groove of the slide plate and the engagement hole of the leg unit.

4. The casing angle adjustment mechanism according to claim 2 , wherein
the stopper is U-shaped, and
both ends on one side having an opening of the stopper being rotatably connected to the rear side of the casing, and another side being the part of the stopper that is passed through and engaged with the engagement groove of the slide plate and the engagement hole of the leg unit.

5. The casing angle adjustment mechanism according claim 1 , wherein the engagement groove of the slide plate includes a slope part sloping toward the surface of the slide plate as it approaches a side having the first protrusion.

6. The casing angle adjustment mechanism according claim 2 , wherein the engagement groove of the slide plate includes a slope part sloping toward the surface of the slide plate as it approaches a side having the first protrusion.

7. The casing angle adjustment mechanism according claim 3 , wherein the engagement groove of the slide plate includes a slope part sloping toward the surface of the slide plate as it approaches a side having the first protrusion.

8. The casing angle adjustment mechanism according claim 4 , wherein the engagement groove of the slide plate includes a slope part sloping toward the surface of the slide plate as it approaches a side having the first protrusion.

9. The casing angle adjustment mechanism according to claim 1 , wherein the engagement hole of the leg unit includes a slope part sloping toward a surface of the leg unit as it approaches the one side of the leg unit.

10. The casing angle adjustment mechanism according to claim 1 , wherein an edge of the slide plate is slidably inserted into a groove part formed on the side wall of the leg unit.

11. An electronic device comprising:
a casing; and
the casing angle adjustment mechanism according to claim 1 .

12. An electronic device comprising:
a casing; and
the casing angle adjustment mechanism according to claim 2 .

13. An electronic device comprising:
a casing; and
the casing angle adjustment mechanism according to claim 3 .

14. An electronic device comprising:
a casing; and
the casing angle adjustment mechanism according to claim 4 .

15. An electronic device comprising:
a casing; and
the casing angle adjustment mechanism according to claim 5 .

16. An electronic device comprising:
a casing; and
the casing angle adjustment mechanism according to claim 6 .

17. An electronic device comprising:
a casing; and
the casing angle adjustment mechanism according to claim 7 .

18. An electronic device comprising:
a casing; and
the casing angle adjustment mechanism according to claim 8 .

19. An electronic device comprising:
a casing; and
the casing angle adjustment mechanism according to claim 9 .

20. An electronic device comprising:
a casing; and
the casing angle adjustment mechanism according to claim 10 .
