JPH01122894A - Intrusion preventive mechanism in escalator device - Google Patents

Abstract

PURPOSE: To entirely block from the tread to the height of a manual handrail so as to positively prevent an entry action by providing an entry preventing fence rotatably in the landing position of at least one of inner side plates erected on both sides of steps. CONSTITUTION: Entry preventing mechanism 5 is provided in the landing position of inner side plates 2 erected on both sides of steps 3. The preventing mechanism comprises a plurality of hinges 5a and a pair of entry preventing fences 5b. The entry preventing fences 5b are rotatably fitted to the respective inner side plates 2 through the hinges 5a and normally enclosed in recessed storage parts 2a provided at the inner side plates 2 so as to be flush as well as fixed by exclusive keys 5c so as not to open. When activation is stopped, the fixed state of the entry preventing fences 5b is released by the exclusive keys 5c and rotated, and the entry preventing fences 5b are fixedly connected to each other by a connecting bar 5d. The landing is therefore blocked entirely from the vicinity of the tread to the height of a moving handrail 4 to positively prevent entry.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an intrusion prevention mechanism in an escalator device such as an escalator or a moving walkway.

[Conventional technology]

The conventional device, as described in Japanese Patent Application Laid-open No. 59-92887, incorporates an intrusion prevention chain after the escalator starts and stops on the side facing the railing of the entrance, and while the escalator is stopped, the chain is placed between the two railings. At the same time, the unlocking of the chain outlet was also used as the starting key, and the escalator's starting circuit was stopped while the access prevention fence was being unlocked.

[The interlayer point that the invention attempts to solve]

In the above conventional technology, a single chain is simply stretched between both railings, so it is easy for the user to crawl under or cross over the intrusion prevention chain, and it has little function as an intrusion prevention. I couldn't accomplish it. An object of the present invention is to provide an intrusion prevention mechanism for an escalator device that can reliably prevent intrusion with a simple configuration.

[Means for solving problems]

The above purpose is to place one part at the position of the entrance/exit on the inner side plate.
This is achieved by providing an intrusion prevention fence that is attached to at least one of both inner plates so that it can be rotated and transmitted freely.

[Effect]

When in use, the entry prevention fence attached to each inner panel is raised to completely seal off the boarding entrance so that no one can crawl under or step out, easily and reliably preventing users from entering. You can.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In these figures, 1 is an escalator, and 2 is an inner plate constituting this escalator, which is erected on both sides of a step 3 that rotates between two entrances and exits. 4 is step 3
This is a moving handrail that moves in synchronization with the handrail. Reference numeral 5 denotes an entry prevention mechanism provided at the entrance/exit (two locations) on the inner side plate 2. This intrusion prevention mechanism 5 consists of a plurality of hinges 5a and a pair of intrusion prevention pIr5b, each of which has an intrusion prevention fence 5b.
is attached to each inner plate 2 via a hinge 5a. Normally, the inner plate 2 has a concave storage portion 2a for accommodating the intrusion prevention member 15b, so that the intrusion prevention fence 5b is flush with the inner plate 2. At this time, the entry prevention fence 5b is
It is fixed so that it does not open at 15c. When the escalator 1 is stopped, the intrusion prevention fence 5b is unlocked using the special key 5C, and the escalator 1 is pulled up from the storage section 2a on the inner plate 2.
The entry prevention fences 5b are fixed to each other by connecting rods 5d at the entrance.

Furthermore, when starting the escalator 1, the pair of intrusion prevention devices 15b provided on the inner plate 2 are stored flush with the inner plate 2 in the storage portion 2a of the inner plate 2, and are fixed with a special key. This does not impede users' ability to get on and off the train in any way. Also, when the escalator 1 starts or stops, the storage section 2 of the inner board 2 can be opened by releasing the dedicated 15c.
Raise the intrusion prevention fence 5b from a, and open the pair of intrusion prevention fences 5.
By aligning both ends of the escalator b and fixing it with the connecting rod 5d, the entrance can be completely closed off from the vicinity of the tread of the step 3 to the height of the moving handrail 4, making it easy for users to enter the escalator 1 when it starts or stops. It can be definitely prevented.

Furthermore, it would be more convenient for safety if a means such as a switch is provided to prevent the escalator 1 from starting or to stop the escalator 1 when the above-mentioned exclusive use 115c is released.

〔Effect of the invention〕

As described above, the entry prevention mechanism in the escalator device of the present invention can completely block the boarding entrance from the vicinity of the step tread to the height of the moving handrail with the entry prevention fence, thereby preventing users from entering the escalator device. It also has the effect of reliably preventing it.
