Abstract

A stand structure for an article includes: a pin engaging groove formed in an article body; a pivot portion formed below the pin engaging groove and supporting a first arm of a stand; and an engaging portion disposed in a second arm of the stand and engaged with the pin engaging groove. A switching position exists within a range of the pin engaging groove. When, in a state where the bottom portion and the coupling portion are butted against the placement surface, the engaging portion is engaged with a portion of the pin engaging groove which is located at a position lower than the switching position, the article body is supported in a backward inclined state by the stand.

First claim

What is claimed is:

1. A stand structure for an article including an article body having a top portion, a bottom portion, and a back surface, the stand structure comprising:
a stand including a first arm having a first end and a second end, and a second arm having a third end and a fourth end;
a pin engaging groove including a guide groove and an engagement groove disposed in the article body, the engagement groove being disposed at a lower end of the guide groove;
a fixed pivot portion disposed in the article body and spaced from the pin engaging groove, and
a coupling portion at which the second and third ends are pivotably connected to each other,
wherein the first end is pivotally connected to the fixed pivot portion so that the first arm is only pivotable,
wherein the fourth end includes an engaging portion engaged with the pin engaging groove and configured to be slidable along the guide groove and the engagement groove,
wherein the second arm is movable to a backward inclined position and to a forward inclined position, and
wherein, in the backward inclined position, the bottom portion and the coupling portion rest on a placement surface, while the engaging portion is engaged with the engagement groove disposed at a the lower end of the guide groove.

2. The stand structure according to claim 1 , wherein:
the guide groove extends straightly in the substantially longitudinal direction of the article body, and
the engagement groove is forwardly bent from a lower end of the guide groove.

3. The stand structure according to claim 1 , wherein:
the engagement groove includes a first engagement groove and a second engagement groove each of which are forwardly bent from positions lower than the switching position.

4. The stand structure according to claim 1 , wherein:
the guide groove has:
a front restricting portion configured to restrict a front limit position for the engaging portion in the guide groove; and
a rear restricting portion configured to restrict a rear limit position for the engaging portion in the guide groove, and

in a state where the bottom portion and the coupling portion are resting on the placement surface:
the engaging portion rests against the rear restricting portion when the second arm is in the backward inclined position, and
the engaging portion rests against the front limit position or the engagement groove when the second arm is in the forward inclined position.

5. The stand structure according to claim 4 , wherein:
in a case where, while the bottom portion and the coupling portion are separated from the placement surface, the posture of the article body is changeable between a supine posture, where the back surface is able to rest on the placement surface and a vertically standing posture, where the bottom portion is able to rest on the placement surface, and the engaging portion rests against the engagement groove or the rear restricting portion.

6. The stand structure according to claim 1 , wherein:
the bottom portion has a flat surface that, when the stand supports the article body in a backward inclined posture, is opposingly resting in parallel against the placement surface.

7. The stand structure according to claim 1 , wherein:
the back surface of the article body has an accommodating concave portion,
the pin engaging groove and the pivot portion are disposed in the accommodating concave portion, and
when the coupling portion is accommodated in the accommodating concave portion, the stand in entirety is accommodated in the accommodating concave portion.

8. The stand structure according to claim 1 , wherein:
the second arm moves through a switching position disposed within a range of the pin engaging groove, and
when the second arm is switched between the backward inclined position and the forward inclined position, the engaging portion passes through the switching position.

9. The stand structure according to claim 8 , wherein:
the guide groove extends in a substantially longitudinal direction of the article body; and
the engagement groove extends continuous from the guide groove, and is forwardly bent from a position lower than the switching position, and,
when, in a state where the bottom portion and the coupling portion are resting on the placement surface, the engaging portion is engaged with the engagement groove, the stand supports the article body in a backward inclined posture.

10. The stand structure according to claim 8 , wherein:
the engagement groove is forwardly bent from a position between the switching position and a lower end of the guide groove.

11. That stand structure according to claim 1 , wherein:
the posture of the article body is changeable from a supine posture, where the back surface is able to rest on the placement surface, and a vertically standing posture, where the bottom portion is able to rest on the placement surface.
