Description

  The present invention relates to an anti-skid device for passenger conveyors.

  Passenger conveyors transport passengers when they ride on moving stairs, and are laid between two floors having different heights in a building. The inclination angle of a passenger conveyor that is stretched between two floors having different heights is generally 30 °.

  By the way, when a plurality of passenger conveyors are installed, a plate-like body called an outer deck cover is installed between two adjacent passenger conveyors in order to protect the gap and improve the design. Is common.

  However, since the outer deck cover is installed at an inclination angle of 30 ° in accordance with the inclination angle of the passenger conveyor, if the passenger accidentally releases his / her carrying items such as a mobile phone or handbag on the outer deck cover, the outer deck cover is released. It is also possible for the carry-on item to slide down to the lower floor along the outer deck cover and break, or to collide with another passenger on the lower floor. For this reason, the passenger conveyor equipped with the outer deck cover is required by the owner or manager of the passenger conveyor to include a means for preventing the articles from slipping.

  Conventionally, as a slip-preventing means provided on the outer deck cover of the passenger conveyor, a plurality of box-shaped slip-preventing devices that also serve as a display device are fixed on the outer deck cover with a space between them. For example, see Patent Document 1.)

Japanese Patent Application Laid-Open No. 07-242385

  However, since the anti-skid device according to the prior art is fixed to the upper surface of the outer deck cover as a whole, a passenger's finger holding the moving handrail collides with the anti-skid device, or the moving handrail and the anti-skid device There is a problem that it is easily caught between the two.

  In addition, if a sufficiently large gap is provided between the moving handrail and the anti-skid device, the occurrence of such a problem can be avoided, but on the other hand, sliding of small items such as mobile phones and key holders can be prevented. It is difficult to prevent because it is difficult to prevent.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a passenger conveyor slip-off prevention device that can prevent a passenger from slipping down without causing a passenger to pinch a finger between the moving handrail of the passenger conveyor and the slip-down prevention device. .

  DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of a slip-off prevention device according to the present invention will be described based on the drawings.

  FIG. 1 shows a state in which two passenger conveyors are provided along the wall surface W in the building. The first passenger conveyor 1a includes a plurality of steps 3a that circulate and move through the entrance and exit, and a moving handrail 2a that is provided outside the step 3a in the width direction and circulates and moves through the entrance and exit in conjunction with the step 3a. Yes. The second passenger conveyor 1b includes a plurality of steps 3b that circulate and move through the entrance and exit, and a moving handrail 2b that is provided outside the step 3b in the width direction and circulates and moves through the entrance and exit in conjunction with the step 3b. Yes. The moving direction of the step 3b and the moving handrail 2b may be the same direction as the step 3a and the moving handrail 2a, or may be the opposite direction to the step 3a and the moving handrail 2a.

  In order to protect the gap and improve the design between the wall W of the building and the first passenger conveyor 1a and between the first passenger conveyor 1a and the second passenger conveyor 1b, the outer deck A cover 4 is installed. The upper surface of the outer deck cover 4 is lower than the upper part of the moving handrails 2a and 2b in the inclined portions of the passenger conveyors 1a and 1b, and is almost the same height as the upper part of the balustrade where the moving handrails 2a and 2b are provided. Yes.

  As shown in FIG. 1, one or more (three in the example of FIG. 1) slipping prevention devices 5 are installed on the inclined portion of the outer deck cover 4 along the inclination of the passenger conveyor. The slip-off prevention device 5 is a device for receiving an object that slides down on the outer deck cover 4 from above the passenger conveyors 1a and 1b, and further preventing it from sliding down. Accordingly, each anti-skid device 5 is attached to the center position of the outer deck cover 4 in the width direction.

  2 and 3 show a first example and a second example of the anti-skid device 5 according to the embodiment. As shown in FIG. 2, the anti-skid device 5 according to the first example inserts the revolving body 53 into the holding hole 52 formed in the fixed body 51 by rotatably inserting the shaft portion 54 of the revolving body 53. It is characterized by being held by the fixed body 51 so as to be able to turn. Further, as shown in FIG. 3, the anti-skid device 5 according to the second example inserts a holding shaft 55 erected on the fixed body 51 into a center hole 56 formed in the revolving body 53 so as to be freely rotatable. Thus, the swiveling body 53 is held on the fixed body 51 so as to be turnable. As shown in FIG. 5, the fixed body 51 is fixed to the upper surface of the inclined portion of the outer deck cover 4 with screws 6.

  As shown in FIGS. 2 to 4, at least three or more (three in the example of FIGS. 2 to 4) are provided on the revolving body 53 in order to reliably stop the object sliding on the outer deck cover 4. ) Swirl blades 57 are provided. Each swirl blade 57 has a tip end portion of the handrail 2a, 2b or 2a of the passenger conveyor, as shown in FIGS. 4 and 5, in order to prevent slipping of small objects such as mobile phones and key holders. The gap between the moving handrails 2a and 2b of the passenger conveyor or the wall surface W provided to the passenger conveyor is formed to be small so as not to contact the wall surface W provided to the passenger conveyor.

  A flexible body 58 such as a rubber sheet, for example, is provided at least at the tip of the swirl blade 57 in order to reduce an impact when a foreign object such as a passenger's finger collides. The swirl vane 57 and the flexible body 58 are integrated by an adhesive or the like. The flexible body 58 can be omitted, or the entire swirl vane 57 can be formed of a flexible body.

  The slip prevention device 5 is provided with a return member so that an object sliding on the outer deck cover 4 can be stopped more reliably. As the return member, a weight 59 embedded in the swirl vane 57 can be used as shown in FIG. 2, or it is stretched between the fixed body 51 and the swivel body 53 as shown in FIG. A return spring 60 can also be used.

  Thus, when the slip prevention device 5 is provided with the return member (weight 59, return spring 60), as shown in FIG. 7, each swirl blade 57 is set in a predetermined state in a steady state where no object is received. Therefore, the object sliding down on the outer deck cover 4 can be surely stopped.

  That is, as shown in FIG. 2, when the weight 59 is embedded in one of the three swirling blades 57, when attached on the outer deck cover 4, as shown in the left diagram of FIG. In the state where one swirl blade 57 in which the weight 59 is embedded is faced down, the anti-skid device 5 can be stably held. When the weight 59 is embedded in two of the three swirl blades 57 or when the return spring 60 is stretched between the fixed body 51 and the swivel body 53, the right side of FIG. As shown in the figure, the anti-sliding device 5 can be stably held with one swirl blade 57 facing upward.

  Hereinafter, the operation and function of the anti-skid device 5 according to the embodiment will be described.

  When a passenger slides a relatively large carrying item (object) such as a handbag on the outer deck cover 4, the object often slides along the center position of the outer deck cover 4 in the width direction. Therefore, in this case, the object that has been slid down is received by the shaft center portion of the anti-sliding device 5, and further sliding down is prevented. In this case, the turning body 53 hardly turns.

  On the other hand, when a passenger slides a relatively small object such as a mobile phone on the outer deck cover 4, the object moves along an intermediate position between the moving handrails 2a and 2b and the slip prevention device 5. May slide down. Therefore, in this case, the slipped object is received by the swirl vane 57 of the slip prevention device 5. When the slid down object is received by the swirl vane 57, the swiveling body 53 swivels in one direction by the force. However, since the swing body 53 is provided with return members such as the weight 59 and the return spring 60, the swing operation of the swing body 53 is performed within a limited range of the swing angle. Therefore, the slid object does not slip through the intermediate position between the moving handrails 2a, 2b and the anti-sliding device 5, and further object slid is prevented.

  If the object that has been slid down is removed, the swinging body 53 automatically returns to the original position by the return action of the return members such as the weight 59 and the return spring 60.

  Moreover, since the swivel body 53 is arranged in the slip prevention device 5 according to the embodiment with the tip of the swirl vane 57 approaching the moving handrails 2a and 2b, the passengers on the passenger conveyors 1a and 1b are raised or lowered. Even if a hand that grabs the moving handrails 2a and 2b hits the anti-sliding device 5 while the handrail is in motion, the revolving body 53 turns by that force. For this reason, since the big clearance gap arises between the moving handrails 2a and 2b and the anti-sliding apparatus 5, the passenger of a passenger conveyor does not pinch a hand.

  Furthermore, since the slip prevention device 5 according to the embodiment has the flexible body 58 provided at the tip of the swirl vane 57, if the passenger conveyor 1a and the passenger conveyor 1b are operated at the same speed in the same direction, A flexible body 58 provided at the tip of the swirl vane 57 even when the passenger on the passenger conveyor 1a grasps the moving handrail 2a and the hand on the passenger conveyor 1b grasps the moving handrail 2b at the same time contact the anti-skid device 5. However, passengers do not pinch their hands.

  In addition, this invention is not limited to the range of above-described embodiment, It can implement in various deformation | transformation in the range which does not deviate from the summary of this invention.
