Abstract

PURPOSE:To fix and set a safety fence at the front side of an entrance opening by connecting the third rod positioned at the middle height of the entrance opening from the inner side of an elevator shaft, and the second rod of the safety fence, so as to hold and press the wall surface of the elevator shaft with the second rod and the third rod. CONSTITUTION:The first connecting member 21 and the second connecting members 23 are connected by the first joints 22 to form a reverse portal type frame body. Then the first pipe 25, the second pipe 26, and a sheet 24 furnishing a baseboard 27 are installed to the frame body with the second joints 28, the third joints 29, and the fourth joints 30 to incorporate the sheet 24 and the frame body, and it is put against the entrance opening 6 of an elevator. Then, by pulling the hooks 32C and 32C of the third pipe 31 positioned at the inner side of an elevator shaft 8, the hooks 32C and 32C are fitted to the 8-shape rings 32A and 32A of the second pipe 26. In such a condition, the second pipe 26 and the third pipe 31 hold a wall surface 9 elastically with rubber bands 32B and 32B, and a safety fence 20 is fixed to the wall surface 9 as the result.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a safety fence for closing an elevator landing opening;
More specifically, the present invention relates to a safety fence that can be easily and safely installed.

[Conventional technology]

As a conventional safety fence of this type, for example,
There are those described in Japanese Patent Application Laid-open No. 177649 and Japanese Patent Application Laid-open No. 162822/1983. The safety fence described in these documents will be explained with reference to FIGS. 9 to 11. This safety fence (1)
comprises a seat (2), a first pipe (3), a second pipe (4) and a skirting board (5) respectively attached to the upper end, middle and lower end of the seat (2), and the elevator hall opening It is installed in the front of the section (6) and is configured to close the hall opening (6). That is, the safety fence (1) is secured to the wall surface (9) of the hoistway (8) by means of a pair of handles (7), (7) attached to both ends of the first pipe (3) located at the upper end of the safety fence (1). ) is fixed.

As shown in FIG. 10, the fixture (A) includes a clamp (71) that grips the first pipe (3),
), and grip claws (73) connected to the support member (72) and gripping the wall surface (9). This gripping claw (73) is a first gripping claw (7
3A), a second gripping claw (73B), and a support portion (73C) that allows these gripping claws (738) and (73B) to expand and contract. Note that (73D) is a bolt for fixing the gripping claw (73) to the wall surface (9).

When installing the safety fence (1) above at the landing opening (6), fix the fixtures (7) and (7) on the wall surface (9) near the upper end of the landing opening (6) and attach the first pipe (3) is fixed.

(Problem to be Solved by the Invention) However, when installing the conventional safety fence (1) at the landing opening (6) of an elevator, it is usually 1.8 to 2.0 m from the floor of the landing. The first pipe (3) must be fixed at a height of . As a result, short workers must use a stepladder to install the safety fence (1), making work difficult.
There was a risk of falling inside. Furthermore, as shown in Fig. 10, after filling the opening end of the three-sided frame (10) and wall surface (9) with mortar in the landing opening (6), attach the fixture (7) to the wall surface (9).
9), and the safety fence (1) cannot be attached to the wall (
9) could not be fixed.

In addition, when installing a safety fence, is there a proposal for protective equipment for elevator entrances and exits that eliminates the need to work at heights (Japanese Utility Model Publication No. 52-29730)?
No countermeasures were taken after the incident.

The present invention was made to solve the above problems, and
To provide a safety fence for an elevator hall opening that can be easily and safely installed at a low position and can be installed regardless of the presence or absence of a three-sided frame.

(Means for Solving the Problems) The safety fence of the elevator landing opening of the present invention includes a first connecting portion that is longer than the width of the elevator landing opening, and a first connecting member that is attached to both ends of the first connecting member. a pair of second connecting members attached to one joint and extending near the upper end of the hall opening; and a second joint, a third joint, and a fourth joint at the upper, middle, and lower ends of the pair of second connecting members, respectively. A sheet having a first rod, a second rod, and a skirting board that fit together, and a sheet that is parallel to and tightened to the second rod of the sheet and presses the second connecting member and the hoistway wall, so that the sheet is It is equipped with a third rod fixed to the front surface of the hall opening.

[Effect]

According to the present invention, after the second connecting member is connected to the first connecting member via the first joint, the first rod of the safety fence body is connected to the second to third joints attached to the second connecting part Δ. , After connecting the second rod and baseboard and integrating the safety fence body with each connecting member and leaning it against the elevator landing opening, the third rod is positioned at the middle height of the landing opening from the inside of the hoistway. By connecting the safety fence with the second rod of the safety fence body, the safety fence can be fixedly installed in front of the hall opening by pressing the wall surface of the hoistway with the second rod and the third rod.
