Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an escalator step carrier.

[0002]

2. Description of the Related Art Generally, the steps of an escalator are about 80 kg to 150 kg for a wheelchair, and it is difficult or impossible for one worker to lift the steps.

Therefore, when carrying the steps of the escalator, the steps are mounted on a truck using a lifting device, and the truck is moved. Also, when the steps are lowered from the cart onto the floor or the like, the lifting device is used.

[0004]

In the above conventional example, a bogie and a lifting device are required, and there is a problem that workability is extremely poor.

An object of the present invention is to provide an escalator step carrier which can solve the above problems.

[0006]

An object of the present invention is to provide a tread member having a cleat groove, a riser surface member connected to the tread member, and a pair of rear wheels provided on a free end side of the riser surface member. And a set bolt mounting hole provided at a free end side of the tread member, and a step for carrying the escalator detachably provided on the free end side of the tread member of the step. In the tool,
A hexagonal prism portion that can be engaged with a tool, a screw portion formed at the upper end of the hexagonal column portion and screwed into the mounting hole for the set bolt, and a free wheel provided at a lower end of the hexagonal column portion It is achieved by doing.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG.
Explanation will be made based on FIG.

In FIG. 1, the steps 1 of the escalator are:
A step member 2 having a cleat groove formed therein, and the step member 2
, A pair of rear wheels 4 provided on the free end side 3a of the riser surface member 3, and a set bolt mounting hole 5 provided on the free end side 2a of the tread surface member 2 of the step 1. And Free end side 2a of tread member 2 of step 1
Carriers 6 and 7 are detachably provided in the set bolt mounting holes 5 provided in. Carriers 6 and 7 are hexagonal column portions 8
And a screw portion 9 formed at an upper end of the hexagonal column portion 8 and a universal wheel 10 provided at a lower end of the hexagonal column portion 8.
The screw portion 9 is set to a size that can be screwed into the set bolt mounting hole 5. The universal wheel 10 is located at the lower end of the hexagonal column 8,
It has a support frame 11 rotatably mounted and a tire 12 rotatably mounted on the support frame 11. A moving handle 13 is detachably provided in a part of the set bolt mounting hole 5. The moving handle 7 is substantially U-shaped as shown in FIG. The pair of rear wheels 4 are provided with protective covers 14 as shown in FIG. When the step 1 is transported to a predetermined place or the like, the protective cover 14 shown in FIG.
As shown in FIG. The transporters 6, 7 and the moving handle 13 are also fixed to the tread surface 2 as shown in FIG. 1 when transporting the steps 1 to a predetermined place or the like. The tire 12 is formed from an elastic body. Protective cover 14
Is formed from a material that does not damage the floor surface.
The set bolt mounting hole 5 is a screw hole. The screw portions 9 of the vehicles 6 and 7 screwed into the screw holes are fixed to the tread surface member 2 by the nuts 15.

Due to the above structure, when the step 1 is to be transported, the carrying tools 6, 7 are inserted into the set bolt mounting holes 5.
Attach the moving handle 13 and attach the protective cover 14 to the rear wheel 4.
Is pressed, the step 1 is transported to a predetermined place without difficulty by the rear wheel 4 provided on the protective cover 14 and the free wheels 10 of the transporters 6 and 7. Also, the mounting holes 5 for set bolts are used to mount the vehicles 6 and 7,
There is no need to apply any processing to the steps 1.

As described above, according to the present embodiment, the steps 1 can be transported to a predetermined place without using a bogie lifting device.

[0011]

As described above, according to the present invention, there is provided an escalator step carrier which can be moved without difficulty without using a bogie or a lifting device.
