JP2507657B2 - Escalator device - Google Patents

Description

Description: TECHNICAL FIELD The present invention relates to an escalator device having a wheelchair step on which a wheelchair can be mounted, and more specifically, restrains wheels of a wheelchair mounted on the wheelchair step. This is related to the improvement of the bollard.

[Conventional technology]

In recent years, for the purpose of enhancing welfare and convenience for wheelchair users, an escalator has a wheelchair step that transforms from a normal step configuration into a special configuration that allows a wheelchair to be installed between a plurality of normal steps when driving a wheelchair. The group is intervening.

This wheelchair step group is, for example, Japanese Patent Publication No. Sho 63-19438.
As disclosed in Japanese Patent Laid-Open No. 63-51956 and the like, a first step having therein a retractable fork that penetrates through a curved back surface and projects rearward, and a rear step behind the first step. It is composed of a movable step plate which is installed and scooped up by the fork, and which is movable up and down, and a second step which has a steel wheel stopper that projects upward and restrains the wheel of the wheelchair. Then, the wheelchair step group carries and carries general passengers during normal operation of the escalator, and during wheelchair operation, movable members such as forks, movable treads, and car stops move to perform transformation operations. However, it has the function of carrying a wheelchair on board.

[Problems to be Solved by the Invention]

The conventional escalator device is constructed as described above, and since the wheel stopper for restraining the rear wheel of the wheelchair is made of steel and is extremely heavy, it is difficult to manufacture, assemble, install, maintain and perform other processing and handling.

The present invention has been made in view of the above, and an object thereof is to provide an escalator device capable of reducing the weight of a car stop.

[Means for solving the problem]

In the present invention, in order to achieve the above-mentioned object, a wheelchair step that can mount a wheelchair is interposed between a plurality of steps of an escalator, and inside the wheelchair step, the wheelchair steps project outwardly and upward during wheelchair operation. A wheel stop for restraining the wheel of the wheelchair mounted on the wheelchair steps is arranged so that it can be retracted and retracted, and both sides of the wheel stop are made of steel, and the intermediate portion located between the both sides is made of a lightweight member. It is characterized by being configured.

[Action]

According to the present invention, both sides of the car stop are made of steel that is not easily deformed, and the intermediate portion located between the both sides is made of a lightweight member such as light metal or industrial plastic. Can be realized.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to an embodiment shown in FIGS. 1 and 2. In the drawings, (1) is vertically movably accommodated in a second step forming the wheelchair step group. A plurality of guides (2) are attached to the lower surface of the movable tread (1) having a large number of cleats, and the plurality of guides (2) are attached to the movable tread ( 1) The car stoppers (3) that can be retracted and project through the both sides of the rear part and project upward to the outside are slantably fitted. The substantially fork-shaped bollard (3) is an intermediate portion (4) which is a lightweight main body made of light metal such as aluminum or industrial plastic.
And side portions (6) made of steel, which are respectively screwed with bolts (5) on both sides of the intermediate portion (4). As shown in FIG. 1, the wheel stop (3) is located slightly below the tread surface of the movable tread (1) during normal operation of the escalator, and is shown in FIG. 2 during wheelchair operation of the escalator. As shown, the movable treads (1) fall out from the movable treads (1) of the wheelchair facing the rear wheel (not shown) of the wheelchair on the movable treads (1) protruding outward from the through holes on both sides of the rear. Run a function to prevent.

As described above, according to the present invention, the side portion (6) of the bollard (3) is made of steel so that it is not easily deformed even when a foreign substance comes into contact or collides from the lateral direction, and at the same time, the bollard (3). Since the intermediate portion (4) is made of light metal or industrial plastic that contributes to weight reduction, it is possible to significantly reduce the weight of the car stop (4). Further, along with this weight reduction, it is expected that processing and handling such as production, assembly, installation, and maintenance will be greatly facilitated. Further, it is possible to surely reduce the vibration and impact of the car stop (3) based on the inertial weight during the vertical movement. It should be noted that the intermediate portion (4) is unlikely to be contacted or collided by a foreign substance in the lateral direction, and therefore, even if it is made of light metal or industrial plastic, there is no particular problem.

In the above-mentioned embodiment, the intermediate portion (4) is made of light metal or industrial plastic. However, it is needless to say that it is not limited to this as long as the weight can be reduced. .

〔The invention's effect〕

As described above, according to the present invention, both sides of the car stop are made of steel, and the intermediate portion located between the both sides is made of a lightweight member, so that the weight of the car stop can be significantly reduced. An escalator device capable of being provided can be provided.

[Brief description of drawings]

FIG. 1 is a sectional explanatory view showing a retracted state of a car stop of an escalator device according to the present invention, and FIG. 2 is a sectional explanatory diagram showing a projected state of a car stop of an escalator device according to the present invention. In the figure, (1) is a movable tread, (2) is a guide, (3) is a car stop, (4) is an intermediate part, and (6) is a side part. The same reference numerals in the drawings indicate the same or corresponding parts.

Claims (1)

(57) [Claims] 1. A wheelchair step for interposing a wheelchair is interposed between a plurality of steps of an escalator, and the wheelchair step is mounted inside the wheelchair step so as to project upward to the outside during wheelchair operation. In the escalator device in which a car stop for restraining the wheel of the wheelchair is arranged so as to be retractable, both side parts of the car stop are made of steel, and an intermediate part located between the both side parts is made of a lightweight member. Escalator device.
