Description

  The present invention relates to an escalator device including a step in which a step is generated in an inclined section, and more particularly, to an escalator device that prevents a step during movement from being lifted.

  Along the shape of the frame straddling the floor surface of the upper floor and the floor surface of the lower floor, a convex curve between the inclined section, the upper horizontal section, the lower horizontal section, and the inclined section and the upper horizontal section In an escalator device having an upper curve section formed and a lower curve section formed in a concave shape between an inclined section and a lower horizontal section, the tip or the heel of a shoe or the like is on the upper stage side in the inclined section If the riser of the step is unconsciously touched, even if the slope section is moved in this state, the step does not rise, but if the curve section is moved, the step of the adjacent step is gradually reduced. Therefore, a frictional resistance is generated between the shoes and the like that are in contact with the riser in the step reduction process, and a phenomenon that the upper step is lifted occurs. When the steps are moved to the horizontal section while being lifted, the raised steps may collide with the comb plate on the getting-on / off floor and be damaged.

  Therefore, conventionally, the step is disposed between the left and right brackets so that the rear wheel side of the step moves while floating and does not move to the upper and lower landing floors, and contacts the front base of the step adjacent to the lower step. The thing which provided the possible lift stopper was proposed (for example, refer patent document 1).

Shokai 60-75375

  By the way, in the conventional escalator device including the patent document, the lift stopper that can come into contact with the front base of the step adjacent to the lower stage is formed of L-shaped steel, and the riser is provided by a bolt attached to the left and right. Along with the base, it is fixed between the left and right brackets. However, in the step of the actual escalator device, the lift stopper is formed of L-shaped steel and avoids the upper bolt by the lower bolt of the two bolts arranged vertically with respect to the bracket. In this way, it is fixed across the left and right brackets together with the riser base. From such a structure, a relatively large gap is formed between the lift stopper and the front base of the step adjacent to the lower stage, and the lift stopper and the front base come into contact with each other only after the rear wheel side of the step is lifted considerably. There was a problem, and the effect of preventing lifting was not sufficiently obtained. It was impossible to fix the lift stopper between the left and right brackets with the upper bolts because the lift stopper was at a height position where it interfered with the front base.

  The present invention has been made from the above-described prior art, and an object of the present invention is to provide an escalator device that can effectively suppress the lifting of the rear wheel side of a step with a simple structure. .

  In order to achieve the above object, the present invention comprises a horizontal cleat, a riser connected to the rear and one end of the cleat and extending downward, a riser base to which the riser is fixed, and a pair of left and right. The front of the step adjacent to the lower step is provided with a step having a bracket for supporting the cleat and the riser base, and a front base erected in front of these brackets. In the escalator device that provides a lift stopper that can come into contact with the base and prevents the step during the movement, the protrusion that can face the front base of the step adjacent to the lower step is provided on the upper surface of the lift stopper. It is characterized by that.

  In the present invention configured as described above, when the rear wheel side of the upper step is lifted, the protrusion provided on the upper surface of the lift stopper comes into contact with the front base of the step adjacent to the lower step, thereby preventing further lifting. And, since the gap between the lift stopper and the front base has an appropriate value due to the protrusion provided on the upper surface of the lift stopper, the lift on the rear wheel side of the step is effectively suppressed. The

  In addition, the present invention is characterized in that the projecting body is integrally formed with the lifting stopper with a mountain shape.

  In the present invention configured as described above, the projecting body is lifted and integrally formed with a stopper with a mountain shape, so that the number of parts can be reduced and the cost can be reduced.

  Furthermore, the present invention is characterized in that the protruding body is made of a piece material welded to the floating stopper.

  In this invention comprised in this way, the protrusion can be easily provided using the existing lift stopper by making the protrusion into the piece material welded to the lift stopper.

  According to the present invention, the gap between the lifting stopper and the front base adjacent to the lower stage is set to an appropriate value with a simple structure in which a protrusion that can face the front base is provided on the upper surface of the lifting stopper. Lifting of the rear wheel side can be effectively suppressed.

  The front wheel guide rail 5 and the rear wheel guide rail 6 protrude along the shape of the frame body 4 between the inclined section 12, the upper horizontal section 13, the lower horizontal section 14, and the inclined section 12 and the upper horizontal section 13. The upper curved section 15 formed in a curved shape and the lower curved section 16 formed in a concave curved shape between the inclined section 12 and the lower horizontal section 14, and the upper horizontal section 13 and the lower horizontal section 14 The end portion has reversal sections, and the steps 7 are guided and circulated through these sections.

  The steps 7 are connected endlessly by a step chain 17. The step chain 17 includes a drive sprocket 18 supported in the upper horizontal section of the frame 3 and a driven sprocket supported in the lower horizontal section. It is wound between the nineteen. The drive sprocket 18 is driven by a drive device 8 controlled by the control device 9. The driving device 8, the control device 9, the driving sprocket 18, and the driven sprocket 19 are covered with an upper landing floor 20 and a lower landing floor 21 that get on and off the step 7.

  Further, the step 7 pivotally supports the front wheel 7A on the upper side and the rear wheel 7B on the lower side at an inclination angle along the inclination angle in the inclined section 12 of the front wheel guide rail 5 and the rear wheel guide rail 6. . Further, as shown in FIGS. 2, 3, 4, and 5, the step 7 includes a horizontal cleat 7 </ b> C, a riser 7 </ b> D that is connected to a rear portion and one end of the cleat 7 </ b> C and extends downward. A riser base 7E to which the riser D is fixed, a bracket 7F that supports the cleat 7C and the riser base 7E as a pair of left and right, and a front base 7G that is installed in front of the bracket 7F, are arranged in two vertically. And a bolt 7H for fixing the bracket to the bracket 7F. In FIG. 4, only the front base 7 </ b> G is shown for convenience regarding the step 7 adjacent to the lower stage.

  The front wheel 7A has a support shaft connected to the step chain 17 and forcibly travels along the front wheel guide rail 5. The rear wheel 7B is a wheel that follows the front wheel 7A, and the rear wheel guide rail 6 is driven by its own weight. Along the road. Therefore, when a large lifting force acts on the step 7, the rear wheel 7B of the step 7 may float. Therefore, when the rear wheel 7B side of the step 7 moves while being lifted and moved to the upper landing floor 20 and the lower landing floor 21 side, the raised step 7 is provided at the tip of the upper landing floor 20 and the lower landing floor 21. It may collide with the comb plate and damage the comb plate or the step 7.

  Therefore, in the present embodiment, there is provided a lift stopper 7I disposed between the brackets 7F and capable of coming into contact with the front base 7G of the step 7 adjacent to the lower step, and the step adjacent to the lower step on the upper surface of the lift stopper 7I. 7 is provided with a protrusion 7J that can face the front base 7G. The projecting body 7J is integrally formed with the lifting stopper 7I so as to have a mountain shape, and has a height of 9 mm, for example. The lifting stopper 7I is fixed to the bracket 7F together with the riser base 7E by the above-described bolt 7H located below.

  In this embodiment, while the passenger is moving (driving) from the lower floor 3F to the upper floor 2F, the tip of the shoe or the like in the inclined section 12 unconsciously moves to the riser 7D of the step 7 adjacent to the upper stage. In this state, when the upper curve section 15 is reached, the step between the adjacent steps 7 gradually shrinks, so that a frictional force is generated between the upper step 7 and the shoes that are in contact with the riser 7D. The rear wheel 7B side of the upper step 7 is lifted by the frictional force. Thus, when the rear wheel 7B side of the upper step 7 is lifted, the projecting body 7J provided on the upper surface of the lift stopper 7I comes into contact with the front base 7G of the step 7 adjacent to the lower step, thereby preventing further lifting.

  According to the present embodiment, a simple structure in which a protrusion 7J that can be opposed to the front base 7G of the step 7 adjacent to the lower stage is provided on the upper surface of the lift stopper 7I, between the lift stopper 7I and the front base 7G. The gap dimension can be set to an appropriate value, and the lift on the rear wheel 7B side of the step 7 can be effectively suppressed. Further, the protrusion 7J is integrally formed with the rising stopper 7I so as to have a mountain shape, so that the number of parts can be reduced and the cost can be reduced. Moreover, it can form in the stopper 7I with thickness easily by setting it as a mountain shape.

  The height of the projecting body 7J is set to 9 mm in order to set the gap between the projecting body 7J and the front base 7G to an appropriate value, and it goes without saying that it can be set arbitrarily.

  Here, another embodiment of the escalator device according to the present invention will be described based on FIGS. 6, 7 and 8. FIG. In addition, the same code | symbol is attached | subjected to the thing equivalent to what was mentioned above.
