Abstract

In an elevator controlling panel, an opening portion of a front surface of a case is opened and closed by a front cover. A bent portion is disposed on a first end portion in a width direction of the front cover. A slit is disposed on the bent portion. A shaft member that guides opening and closing operations of the front cover by being moved relatively along the slit, and that also stops the front cover from dislodging from the case, is disposed on a side surface of the case. The slit has a shape such that the opening portion is opened by sliding the front cover forward relative to the controlling panel main body and then upward.

First claim

The invention claimed is:

1. An elevator controlling panel comprising:
a controlling panel main body that has a case having a front surface extending in a vertical plane and defining an opening portion; and
a front cover that opens and closes the opening portion,
wherein:
a bent portion is disposed on a first end portion in a width direction in a plane of the vertically extending front cover;
a slit is disposed on the bent portion;
a shaft member that guides opening and closing operations of the front cover by being moved relatively along the slit, and that also stops the front cover from dislodging from the case, is disposed on a side surface of the case; and
the slit has a shape such that the opening portion is opened by sliding the front cover forward relative to the controlling panel main body, in a forward direction away from the controlling panel main body and perpendicular to the plane of the vertically extending front cover, and then upward in an upward direction in the plane of the vertically extending front cover and perpendicular to the width direction.

2. The elevator controlling panel according to claim 1 , wherein the slit has a shape that enables opening of the opening portion by sliding the front cover upward and then rotating the front cover around the shaft member.

3. The elevator controlling panel according to claim 2 , wherein the bent portion is formed by bending the first end portion in the width direction of the front cover into a Z-shaped cross section.

4. The elevator controlling panel according to claim 1 , wherein:
the shaft member includes:
a shaft portion that is passed through the slit; and
a head portion that is disposed on an end portion of the shaft portion, and that stops dislodging of the shaft member from the slit; and

a clearance is disposed between the head portion and the front cover, the front cover being slidable in the width direction of the case by an amount equal to the clearance.

5. The elevator controlling panel according to claim 1 , wherein:
the front cover is fixed to the case by a cover fixing screw when in a fully closed position; and
a keyhole slot that allows passage of the cover fixing screw is disposed on the front cover.

6. The elevator controlling panel according to claim 5 , wherein a state in which the opening portion is opened is held by hooking onto the cover fixing screw an end of the front cover that is slid upward in the upward direction.

7. The elevator controlling panel according to claim 1 , wherein:
the front cover includes:
a first partial cover; and
a second partial cover that is disposed adjacently above the first partial cover in the upward direction;

the bent portion and the slit are disposed on each of the first and second partial covers; and
the shaft member includes:
a first shaft member that corresponds to the first partial cover; and
a second shaft member that corresponds to the second partial cover.

8. The elevator controlling panel according to claim 7 , wherein:
the slits of the first and second partial covers have shapes that enable opening of the opening portion by sliding the first and second partial covers upward in the upward direction and then rotating the first and second partial covers around the first and second shaft members; and
coupling portions that hold an opened state of the opening portion by coupling with the first and second partial covers in the opened state are disposed on the first and second partial covers.

9. The elevator controlling panel according to claim 7 , wherein:
the slit of the first partial cover has a shape that enables opening of the opening portion by sliding the first partial cover upward in the upward direction and then rotating the first partial cover around the first shaft member;
a hook is disposed on the bent portion of the second partial cover; and
an opened-out state of the first partial cover is held by hooking the first partial cover onto the hook in the opened-out state.

10. An elevator apparatus comprising:
a car that is raised and lowered in a vertical direction inside a hoistway; and
an elevator controlling panel that is disposed inside the hoistway, and on which maintenance work is performed from on vertically topmost top of the car,
the elevator controlling panel comprising:
a controlling panel main body that has a case having a front surface extending in a vertical plane and defining an opening portion; and
a front cover that opens and closes the opening portion,
wherein:
a bent portion is disposed on a first end portion in a width direction in a plane of the vertically extending front cover;
a slit is disposed on the bent portion;
a shaft member that guides opening and closing operations of the front cover by being moved relatively along the slit, and that also stops the front cover from dislodging from the case, is disposed on a side surface of the case; and
the slit has a shape such that the opening portion is opened by sliding the front cover forward relative to the controlling panel main body, in a forward direction away from the controlling panel main body and perpendicular to the plane of the vertically extending front cover, and then upward in an upward direction in the plane of the vertically extending front cover and perpendicular to the width direction.

11. The elevator apparatus according to claim 10 , wherein:
a safety fence is disposed on an upper portion of the car in the upward direction; and
the front cover is slidable until the front cover is higher than an upper end of the safety fence when a floor surface above the car is made level with a lower end of the front cover.
