Description

The present invention relates to a tool dedicated to a passenger conveyor, and more particularly to a tool used to open and close a floor plate on a passenger conveyor.

In a passenger conveyor such as an escalator, a machine room is provided from the entrance to the lower part of the vicinity thereof, and a part of the machine room is closed with a floor plate. The floor plate is provided with a female screw portion in the thickness direction for opening and closing the floor plate. During use of the passenger conveyor, a male screw having a engaging recess (for example, a minus groove) formed at one end thereof is screwed in for the purpose of closing the female screw portion. Hereinafter, this male screw will be referred to as a "screw stopper".

When inspecting the equipment installed in the machine room, it is necessary to open the floor plate that blocks the machine room. A general dedicated tool for opening and closing the floor plate is disclosed in FIG. 20 of Patent Document 1. The conventional tool disclosed in Patent Document 1 has a first bar and a second bar extending perpendicularly from the central portion in the length direction of the first bar to the first bar. It has a T-shape. A male screw portion is formed at one end of the first bar, and the tip of the second bar is formed by a flat-blade screwdriver.

The procedure for opening the floor plate using the conventional tool will be described. First, a flat-blade screwdriver is engaged with the negative groove. The first bar is used as a handle, and the second bar is rotated about the axis of the second bar to loosen the screw stopper and remove it from the female screw portion.

Next, the male screw portion is screwed into the female screw portion from which the screw stopper has been removed, and the tool is fixed to the floor plate. Then, this time, the second bar is gripped as a handle, and the hand holding the second bar is lifted to lift the floor plate and open the machine room.

The tip of the second bar portion is formed at the engagement portion that engages with the engagement recess, and the tip portion of the third bar portion is formed with a male screw that is screwed with the female screw portion. It is characterized by being done.

Further, the second and third bar portions are bifurcated so that the axial center of the one end portion of the first bar portion and the axial centers of each of the second and third bar portions form an equal angle interval. It is characterized by being divided into.

Further, the other end portion of the first bar portion opposite to the one end portion is formed in a hook-shaped portion formed by bending in a hook shape, and the hook-shaped portion moves on the passenger conveyor. It is characterized by being used for attaching and detaching handrails.

According to the passenger conveyor dedicated tool having the above configuration, the floor plate is performed in a state where the male screw formed at the tip of the third bar portion is screwed into the female screw portion provided on the floor plate. In the lifting operation, the first bar portion and the second bar portion, which are bifurcated from the end portion of the third bar portion opposite to the tip portion, are used as handles, and the third bar portion can be gripped and lifted. .. As a result, the unreasonable burden on the wrist is significantly reduced as compared with the above-mentioned conventional tool in which the bar serving as the handle is extended only to one side of the bar on which the female screw portion is formed. The workability of lifting the floor plate is improved compared to the tool of.

Further, in the screw plug removing work performed by engaging the engaging portion of the second bar portion with the engaging recess of the screw stopper and rotating the engaging portion around the second bar portion, the second bar portion is said to be said. The first bar portion and the third bar portion, which are bifurcated from the end on the opposite side of the engaging portion, can be used as handles and rotated. As a result, the workability of removing the screw plug is significantly improved as compared with the case where the bar serving as the handle extends only to one side of the bar on which the engaging portion is formed.

That is, according to the passenger conveyor dedicated tool according to the present invention, the workability of lifting the floor plate is improved as compared with the above-mentioned conventional tool, but the deterioration of the workability of removing the screw plug can be suppressed as much as possible. it can.

After removing the tool 10 from the nut 114, the screw stopper 116 is screwed into the nut 114. A flat-blade screwdriver portion 22 is used when screwing the screw stopper 116 into the nut 114.

[Moving handrail attachment / detachment work]
The procedure for attaching and detaching the moving handrail 126 to the guide rail 128 using the tool 10 will be described with reference to FIGS. 5 and 6. In the work of attaching and detaching the moving handrail 126, the second bar portion 14 and the third bar portion 16 (FIG. 3) are used as handles. Here, in the moving handrail attachment / detachment work, the second bar portion 14 and the third bar portion 16 used as the handle are collectively referred to as the handle portion 26.

Here, first, a case where the moving handrail 126 is detached (removed) from the top to the bottom shown in FIG. 1 will be described. The worker who attaches / detaches the moving handrail 126 stands on the tread 102A of the tread 102 when the traveling is stopped. The operator first stands on the tread 102A of one or two treads 102 located in the upper part of the plurality of treads 102 in the oblique section.

The operator (not shown) holds the handle portion 26 of the tool 10 with one hand, attaches the other hand to the hook-shaped portion 18, and raises the hook-shaped portion 18 as shown in FIG. 5 (a). (Direction of arrow T1), the spherical portion 20 is at the head, and the tip portions of the spherical portion 20 and the hook-shaped portion 18 are pushed into the moving handrail 126 from the gap C1 (FIG. 5 (b)).

As a result, the hook-shaped portion 18 hooks the first end 126A of the moving handrail 126. In this hooked state, the operator pulled the hand holding the handle portion 26 in a substantially horizontal direction (direction of arrow T2) orthogonal to the longitudinal direction of the moving handrail 126, as shown in FIG. 5 (b). After that, as shown in FIG. 5 (c), while maintaining the pulled state (arrow T3), while rotating the tool 10 (hook-shaped portion 18) in the direction of arrow T4, the entire tool 10 is lifted upward. , A part of the moving handrail 126 (a portion hooked by the hook-shaped portion 18 and its vicinity) is removed from the flange portion 128A of the guide rail 128 (FIG. 5 (d)).

Next, the entire tool 10 is tilted (rotated) downward of the moving handrail 126 around the tip portion of the hook-shaped portion 18, and as shown in FIG. 6, the axial center of the first bar portion 12 Make X1 (FIG. 3A) substantially parallel to the longitudinal direction of the moving handrail 126.

With the tip of the hook-shaped portion 18 sandwiched between the moving handrail 126 portion (hereinafter referred to as "disengagement portion") detached from the flange portion 128A and the flange portion 128A, the operator can step on the step. By continuing to pull the hand holding the handle portion 26 in the direction opposite to the hook-shaped portion 18 side (direction of the arrow T5) while descending 102 (FIG. 1) over the section where the moving handrail 126 is oblique, the said Starting from the detached portion, the moving handrail 126 is continuously separated from the flange portion 128A by a length corresponding to the oblique section.

The moving handrail 126 portion separated from one flange portion 128A is pressed toward the other flange portion 128B (FIG. 2C), so that the portion is detached from the guide rail 128.

As described above, some of the series of moving handrail attachment / detachment operations are operations of pulling the hand holding the handle portion 26 of the tool 10 (in the direction of the axis X1 of the first bar portion 12) (FIG. 5B). Arrow T2, arrow T3 in FIG. 6C, and arrow T5 in FIG. 6).

In this case, the hook-shaped portion 18 is provided by grasping the second bar portion 14 and the third bar portion 16 which are the handle portions 26 so as to sandwich the first bar portion 12 between the middle finger and the ring finger. A force is evenly applied to the second bar portion 14 and the third bar portion 16 extending from the axial center X1 of the first bar portion 12 to both sides.

Further, since the second bar portion 14 and the third bar portion 16 serving as the handle portion 26 have a U-shape, they are formed from the index fingers of the hands holding the second and third bar portions 14 and 16. Each of the second joints will line up in a chevron shape over the little finger. The hand in this case has the same shape as shown in FIG. 4 (b).

In this regard, a tool disclosed in Patent Document 2 is known as a dedicated tool for attaching / detaching a moving handrail. The special tool of Patent Document 2 has a hook-shaped portion like the tool 10, but unlike the tool 10, the handle portion is made of a linear elongated metal rod. The pulling operation using the special tool of Patent Document 2 grips the metal rod and pulls the gripped hand in a direction orthogonal to the axis of the metal rod.

Regardless of whether the tool 10 or the special tool of Patent Document 2 is used, a large force is required to elastically deform the moving handrail having a considerable thickness and attach / detach it from the guide rail, and the above-mentioned work of pulling the tool In, the worker puts his weight on the tool.

In this case, the load on the finger of the tool 10 of the handle portion 16 having a U-shape is reduced as compared with the tool of Patent Document 2 of the handle portion having a linear shape.

When the moving handrail 126 is attached to the guide rail 128 (when attached), the work is performed as follows.

First, by manual work without using the tool 10, the flange portion 128B of the guide rail 128 shown in FIG. 2 (c) has a corresponding end portion (in the width direction) over the entire length of the detached portion of the moving handrail 126. The second end 126B side end portion) is fitted.

Then, the tip portion is hooked on the first end 126A of the moving handrail 126. Twist the tool 10 (rotate it around the axis X1) and elastically deform the hooked portion until the hooked first end 126A is located at the tip of the flange portion 128A or outward. (Hereinafter, this part is referred to as an "elastic deformation part".)

Then, as it is, the hand holding the handle portion 26 is continuously pulled in the opposite direction to the first bar portion 12 (hook-shaped portion 18), and the opposite hand is used to move the vicinity of the elastically deformed portion toward the flange portion 128A. By pressing, the moving handrail 126 is continuously fitted into the guide rail 128.

As described above, the tool 10 can be used not only for opening and closing the floor plates 110 and 112, but also for attaching and detaching the moving handrail 126. That is, conventionally, for the opening / closing work and the attaching / detaching work, there are two special tools (for opening / closing work) described in Patent Document 1 and a dedicated tool (for attaching / detaching work) described in Patent Document 2. Where a patent tool is needed, one tool 10 can perform these two tasks.
