DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inclined type passenger transporter such as an escalator, and more particularly, to a moving handrail moving in an ascending direction and a fixed object approaching the moving handrail to form a wedge-shaped space. It relates to the improvement of equipped safety equipment.

[0002]

2. Description of the Related Art In general, passenger transportation (escalator)
A moving handrail provided at the upper end on both sides of the moving handrail and moving in the ascending direction, and a fixed object (obstacle) located close to the moving handrail
A safety device, commonly known as a synthetic resin triangular guard plate, is provided between the vehicle and the passenger. When the passenger's head leaning out of the moving handrail comes into contact with the triangular guard plate, a warning is issued. ) To prevent the worst pinching accidents. As a specific example of this, as an example, a first safety facility (warning oscillating type) and a second safety facility (fixed type for preventing pinching) disclosed in Japanese Patent Application Laid-Open No. 10-139346 are combined to increase safety. There are means.

[0003]

In the above-mentioned conventional safety equipment, in the event that the head or neck of a passenger who actually moves in the ascending direction is supposed to be caught in the accident, the first protection plate is swung. The second safety equipment is fixed, and the fixed object and its front edge are at right angles and 90 degrees crossing, so the head that penetrated the narrowest part The part and neck are retracted, leaving a cause for the pinch accident. This problem is not solved even if the second safety equipment is slightly moved.

The present invention has been made in order to solve such a problem. A passenger moving in a rising direction by a passenger transporter has a moving handrail and a fixed object which approaches the moving handrail to form a wedge-shaped space. In the event of a collision with a safety facility provided in a narrow space between the safety equipment and the vehicle, the narrowed angle at the intersection of the fixed object and the front edge of the safety equipment is eliminated by the inclined front edge to prevent the human body from being pinched. The purpose is to.

[0005]

In order to achieve this object, the present invention relates to a passenger transporter which is installed at an angle between upper and lower floors having a difference in elevation, and a passenger transporter provided at both upper ends of the passenger transporter. The moving handrail provided and located close to the moving handrail,
An approximately triangular first safety device having a vertical front edge, which is mounted in a suspended state at the front of the opening of the wedge-shaped space with a fixed object having a different inclination angle from the moving handrail, and fixed at the rear of the opening. A second safety equipment having a substantially triangular shape having a vertical front edge, wherein the vertical front edge of the second safety equipment intersects with the fixed object. An inclined front edge formed so that the edge and the fixed object do not cross at a right angle is provided.

[0006]

With this configuration, the safety equipment for the passenger transporter of the present invention, particularly, the fixed second safety equipment,
Due to the presence of the inclined front edge, the narrow portion where the fixed object and its front edge intersect has a substantially right-angled portion eliminated, thereby achieving an intersecting shape that does not sandwich the head or neck. For this reason, of course, the effect of greatly improving the safety of the passenger in the narrow part is exhibited.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a safety device for a passenger transporting vehicle to which the present invention is applied. FIG. 1 shows an escalator 1 moving in an ascending direction in an inclined passenger transporter, and a fixed object 2 on an upper portion thereof.
FIG. 2 is a side view mainly showing a first safety facility 3 and a second safety facility 4 at a portion intersecting with (for example, an upper floor).
3 is a side view mainly showing the second safety equipment 4. FIG. As shown in FIG. 1, the escalator 1 is installed at an angle between the upper and lower floors having a difference in elevation, and a step 1A for transporting passengers, and a pair of left and right moving handrails provided on both upper ends of the step 1A. 1B. In addition, the wedge-shaped space Q between the moving handrail 1B and the fixed object 2 (for example, the upper floor ceiling opening) having a different inclination angle from the moving handrail 1B has an opening as viewed from the rising passenger. At the front, a first safety device 3 that maintains a suspended state that can be swung by a free chain 5 with respect to the fixed object 2, and at the rear of the opening at the back of the first safety device 3, there is a fixed object. 2 is provided with a second safety device 4 fixed in a non-swinging state by a screw 6 or the like, and the two types of safety devices 3 and 4 form a triangular portion guard plate which is commonly known. In this case, the first safety equipment 3 is suspended with a gap G between the first safety equipment 3 and the fixed object 2, and the head and baggage of the passenger moving on the steps 1A in the ascending direction are subjected to the first safety equipment. The second safety device 4 fixed at the back position, which is at the narrowest angle and has a wedge-like shape that has a risk of pinching the head or neck, while giving a warning (discomfort due to the collision) while relaxing the impact when colliding with the device 3 The narrow space of the space Q is closed, and the safety facilities 3 and 4 are combined to provide effective protection for passengers.

Here, the first safety equipment 3 which receives a collision force due to the head of the passenger or the like protects the passenger by the configuration shown in FIGS. 1 and 2. That is, in the same manner as in the prior art, a cylindrical shape having a diameter D is formed so that the main plate 3A is opened by the thickness T of the main plate 3A at the front edge of the main plate 3A, which is made of an acrylic resin, at a front portion perpendicular to the main plate 3A. The leading edge body 3B joins the respective contact portions S1 and S2 with a joining agent (joining means) to be integrated. Further, an upper edge body 3C is joined to and integrated with the main plate body 3A with a joining agent (joining means) at a linear upper edge thereof.

On the other hand, the second safety equipment 4 of the present invention is shown in FIG.
As shown in the first safety equipment 3, as in the first safety equipment 3, it has a substantially triangular shape made of an acrylic resin, and its front edge 4A has a vertical front edge 4B orthogonal to the fixed object 2 and is close to the fixed object 2. The narrow portion has an inclined front edge 4C inclined by an angle θ1. As described above, the existence of the inclined front edge portion 4C substantially eliminates a right angle (90 degrees) portion and realizes a cross shape in which the head and the neck are not sandwiched. Reference numeral 4D shown in FIG. 3 is a fixing hole for fixing to the fixed object 2 with the screw 6 (FIG. 1).

In this case, the positional relationship between the first safety equipment 3 and the second safety equipment 4 is as shown by an imaginary line X in FIG.
Even if the first safety equipment 3 is pushed in and moved, it is determined so as not to make contact between them.

The first safety equipment 3 used in the description of the embodiment can be applied to a moving sidewalk which is a passenger transportation like the escalator 1, and the second safety equipment 4 can be applied to the second safety equipment 4. It is also possible to form the inclined front edge into an arc shape having an intersection angle of θ2 as shown by the imaginary line Y in FIG. 3 or to add an inclined front edge as shown by the imaginary line Z at the lower end side. Further, the second safety device 4 of the present invention may be a safety device 7 in which cylindrical front edges 7A and 7B are added to the front edge as shown in FIG. Further, the material and color tone of each of the safety equipments 3, 4 and 7 can be arbitrarily selected as needed.

[0012]

As described above, according to the present invention, the passenger moving in the ascending direction by the passenger transporter moves between the moving handrail and a fixed object such as a ceiling which approaches the moving handrail and forms a wedge-shaped space. When a collision occurs with the provided safety equipment, a narrow angle portion at a portion where the fixed object and the front edge of the safety equipment intersect is eliminated by the inclined front edge, and there is an effect of preventing a human body from being pinched and accidents.
