Description

  The present invention relates to an elevator landing door adjustment jig used for adjusting a gap between a three-way frame and a landing door.

  Conventionally, as a landing door adjustment jig for an elevator, a fixing means for fixing to a door rail and a restriction means for restricting the position of the door hanger in a state of being attached to the door hanger by the fixing means are provided. There is known what is held so that the line and the center line of the door roller coincide with each other (see Patent Document 1).

Japanese Patent Laid-Open No. 2002-87745

  However, in the case of this elevator landing door adjustment jig, it is held by the restricting means so that the center line of the door rail coincides with the center line of the door roller, and is used for adjusting the gap between the three-way frame and the landing door. The problem was that the skill level of the installer greatly affected the installation of the landing door.

  The present invention is intended to solve the above-described problems, and enables quick adjustment to the adjustment of the gap between the three-way frame and the landing door regardless of the skill level of the installer. The purpose is to obtain an elevator hall door adjustment jig.

An elevator hall door adjusting jig according to the present invention includes a three-way frame that forms an entrance / exit on the elevator hall side, and a landing door on which a door hanger that rotatably supports a door roller that rolls on the door rail is attached to the upper surface. An elevator landing door adjustment jig that adjusts the gap between
When attaching the landing door to the door hanger, a regulating portion that abuts against the back surface of the edge of the three-way frame and the upper edge surface of the landing door and regulates the gap between the three-way frame and the landing door; ,
A transition portion is provided continuously from the restriction portion and interposed between the lower surface of the door hanger and the upper surface of the landing door.

  According to the elevator landing door adjusting jig according to the present invention, when the landing door is attached to the door hanger, both the back surface of the edge of the three-side frame and the surface of the upper edge of the landing door are brought into contact with the restriction portion. Thus, the gap between the three-way frame and the landing door is automatically adjusted, and the gap between the three-way frame and the landing door is adjusted quickly regardless of the skill level of the installer.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or equivalent members and parts will be described with the same reference numerals.

Embodiment 1 FIG.
FIG. 1 is a front view showing an entrance / exit of an elevator, FIG. 2 is a perspective view showing the entire landing door 2 of FIG. 1, and FIG.
The elevator entrance / exit device includes a three-way frame 1, a threshold 10, and a landing door 2, which are entrance / exit frames of the landing 3.
On the upper surface of the landing door 2, a door hanger 4 having an L-shaped cross section is fixed by a fastening bolt 8 via a spacer 9. The spacer 9 has a U shape and is interposed between the bracket portion 7 of the door hanger 4 and the upper surface of the landing door 2 with the fastening bolt 8 interposed therebetween.
On both sides of the door hanger 4, door rollers 6 that can roll on the door rail 5 are attached.

FIG. 4 is an overall perspective view showing an elevator landing door adjustment jig 11 (hereinafter, abbreviated as an adjustment jig) used for adjusting the gap between the three-way frame 1 and the landing door 2.
The adjustment jig 11 includes a wooden handle 12, a crossover portion 14, and a restriction portion 13 that restricts a gap dimension between the edge 1 a of the three-sided frame 1 and the landing door 2. The crossover portion 14 and the restriction portion 13 are made of stainless steel and are integrally formed. The restriction portion 13 has a front end portion of the crossover portion 14 that is bent at a right angle, and due to its thickness t, the edge portion 1a and the landing door The gap dimension between the two is regulated. In addition, the dimension of t is about 3-5 mm normally.

In the elevator doorway apparatus described above, the door hanger 4 is fixed to the upper surface of the landing door 2 using the fastening bolt 8 via the spacer 9. At this time, the tightening bolt 8 has the door hanger 4 attached to the landing door 2 in a loose state, and the landing door 2 can be moved forward and backward with respect to the door hanger 4 toward the edge 1 a of the three-sided frame 1. That is, the through hole (not shown) of the landing door 2 through which the tightening bolt 8 passes is a long hole having a long diameter with respect to the edge 1a side.
Next, in a state where the door hanger 4 is temporarily fastened to the landing door 2, the door hanger 4 is lifted away from the landing door 2 to create a gap in the vertical direction, and a crossing portion 14 is formed in each of the gaps from both sides of the landing door 2. Insert the tip of.
Next, the door roller 6 of the door hanger 4 is placed on the door rail 5 in this state.
Thereafter, the regulating portion 13 of the adjustment jig 11 is brought into contact with the back surface of the edge portion 1 a of the three-way frame 1.
In this state, the landing door 2 is pressed against the restricting portion 13 and the door hanger 4 is fixed to the landing door 2 by fully tightening the fastening bolts 8.

According to the adjustment jig 11 of this embodiment, when attaching the landing door 2 to the door hanger 4, both sides of the back surface of the edge portion 1 a of the three-way frame 1 and the surface of the upper edge portion of the landing door 2 are restricted. 13, the gap between the three-way frame 1 and the landing door 2 is automatically adjusted, and the adjustment of the gap between the three-way frame 1 and the landing door 2 is performed once regardless of the skill level of the installer. Adjustment ends with the adjustment work.
Further, since the restricting portion 13 is bent at a right angle with respect to the crossover portion 14 and formed integrally, the adjusting jig 11 is easily manufactured.

Note that a permanent magnet that can be attracted to the upper surface of the landing door 2 or the lower surface of the door hanger 4 may be attached to the crossover portion 14.
By using this permanent magnet, the movement of the adjustment jig 11 with respect to the landing door 2 or the door hanger 4 is prevented, and the adjustment work of the gap between the three-way frame 1 and the landing door 2 is made smoother.

Further, the gap between the three-way frame 1 and the landing door 2 varies depending on, for example, the elevator model and is not a constant value.
In this case, a flat spacer that adjusts the gap between the three-side frame 1 and the edge 1a of the landing door 2 is adhered to the surface of the restriction portion 13 on the three-side frame 1 side. Can do.
The number of spacers is not limited to one, and the number of spacers can be increased or decreased according to the gap size.

It is a front view which shows the entrance and exit of an elevator. It is a perspective view which shows the whole landing door of FIG. It is a principal part longitudinal cross-sectional view of FIG. It is a whole perspective view which shows the landing door adjustment jig | tool of the elevator of FIG.
