JP 2004-269142 A

  In the moving handrail heating device for passenger conveyors of the prior art described in Patent Document 1, a heating wire that generates heat when energized is used as a heating element, and this heating wire is disposed on a heat insulating material provided in a guide rail. By generating heat, the moving handrail is heated by air heat propagation. However, since air has a lower thermal conductivity than metal and the heat of the heating wire generated by energization is difficult to be transmitted to the moving handrail, it takes time until the moving handrail is sufficiently warmed by the heating wire. For this reason, there is a concern that the passenger conveyor cannot be started quickly from a state where the moving handrail generated when the cold district starts early in the morning or the like is frozen and the operating efficiency of the passenger conveyor is lowered.

  Moreover, the moving handrail heating device for the passenger conveyor of the prior art is provided with a plurality of cable pressers for fixing the heating wire on the heat insulating material in the guide rail at intervals from each other in the length direction of the heating wire. . However, since the heating wire is only sandwiched between the lower surface of each cable retainer and the upper surface of the heat insulating material, the heating wire is easily displaced from the initial installation position due to vibration of the passenger conveyor or the like. In such a state, since there is a possibility that the efficiency of air heat propagation from the heating wire to the moving handrail may be reduced, there is a concern that a stable heating effect cannot be obtained for the moving handrail.

  Accordingly, an object of the present invention is to provide a passenger conveyor that can quickly warm a moving handrail and obtain a stable heating effect on the moving handrail.

  In order to solve the above-described problems, the present invention provides a plurality of steps connected endlessly and circulated, a balustrade having a balustrade panel arranged along the moving direction of the steps, and fixed to the upper end of the balustrade. A lower frame supported via a support member; an upper frame fixed to an upper portion of the lower frame; a moving handrail disposed above the upper frame and running in synchronization with the step; and an inner side of the moving handrail In the passenger conveyor provided with a guide for guiding the movement in, in a state of being in close contact with the inner surface of the lower frame, arranged along the moving direction of the moving handrail, and a heating body for heating the moving handrail, The heating body is fixed in the lower frame so as to cover from the lower side, and the positional deviation of the heating body with respect to the lower frame is regulated, and from the heating body Is characterized in that a heat insulating material for blocking the transfer of heat downwardly.

  According to the passenger conveyor of the present invention, it is possible to quickly warm the moving handrail and obtain a stable heating effect on the moving handrail. Problems, configurations, and effects other than those described above will be clarified by the following description of embodiments.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a passenger conveyor according to an embodiment of the present invention.

  The passenger conveyor includes a support structure (frame body) (not shown) installed in the building, and a plurality of steps 3 connected endlessly to circulate and move in the support structure between the entrances 1 and 2 on the upper and lower floors. Have. Then, each step 3 is driven by a driving device (not shown). In addition, the passenger conveyor has a balustrade 4 having a balustrade panel 4A (see FIG. 2) arranged along the moving direction of step 3 on both sides in the width direction in each step 3, and step 3 along the periphery of the balustrade 4 It has the structure which has the moving handrail 5 which drive | works synchronously.

  2 is a cross-sectional view taken along line AA of the moving handrail in the passenger conveyor shown in FIG.

  Under the moving handrail 5, an upper frame 6 and a lower frame 7, which are usually made of stainless steel and are integrally coupled, are arranged. The upper frame 6 is formed in, for example, a U-shape, and is fixed to the upper portion of the lower frame 7 with the opening directed upward. Further, inside the movable handrail 5, there is a guide guide 8 that supports and guides the movable handrail 5 so as to be movable in the longitudinal direction.

  Further, the passenger conveyor is disposed in the vicinity of the boundary between the upper frame 6 and the lower frame 7 along the moving direction of the moving handrail 5 in a state of being in close contact with the inner surface of the lower frame 7, for heating the moving handrail 5. The heating body 9 and the heating body 9 are fixed in the lower frame 7 so as to cover the heating body 9 from the lower side, the positional deviation of the heating body 9 with respect to the lower frame 7 is restricted, and heat is transmitted downward from the heating body 9. And a holding member 11 that holds the heating element 9 from the lower side through the heat insulating material 10.

  As the heating element 9, various heaters such as a heater that is heated by passing electricity and a hot water pipe that is heated by passing warm water can be used. good. In this example, a single case is shown.

  FIG. 3 is a diagram for explaining the configuration of the heat insulating material 10 shown in FIG. 2.

  As shown in FIG. 3, the heat insulating material 10 is formed by, for example, a plurality of materials laminated and is formed of a sheet-like member arranged along the moving direction of the moving handrail 5 like the heating body 9. Yes. Specifically, for example, the heat insulating material 10 is disposed on the lower holding member 11 side to form a surface layer, and uses an aluminum foil 10A that contacts the holding member 11 to protect the inner member, and glass fiber. A glass cloth 10B which is made of woven fabric and forms a heat insulating layer; an adhesive 10C which is applied between the aluminum foil 10A and the glass cloth 10B and bonds the aluminum foil 10A and the glass cloth 10B; and the lower frame 7 It is comprised from the double-sided tape 10D as an adhesive tape which adheres to the inner surface of this, and the release paper 10E adhering to the surface side of this double-sided tape 10D.

  In order to fix the heat insulating material 10 thus configured in the lower frame 7, as shown in FIG. 2, the release paper 10E of the heat insulating material 10 is peeled off from the double-sided tape 10D, and the lower side of the heating body 9 is fixed. The heating body 9 is adhered to the double-sided tape 10D while curving the center side of the heat insulating material 10 in a concave shape in accordance with the shape of the above, and the upper side of the heating body 9 is pressed against the inner surface of the lower frame 7.

  And the part of the both sides of the heating body 9 among the double-sided tape 10D of the heat insulating material 10, that is, the heating body 9 so that the gap formed between the lower frame 7, the heating body 9, and the heat insulating material 10 becomes small. The heat insulating material 10 can be attached to the lower frame 7 and the heating body 9 integrally by adhering the non-adhered portion to the inner surface of the lower frame 7. In addition, the width of the heat insulating material 10 is adjusted in advance so that the portion of the inner surface of the lower frame 7 that is in contact with the upper frame 6 is covered with the heat insulating material 10. It is adjusted in advance according to the length of 9.

  4 is a BB cross-sectional view of the moving handrail in the passenger conveyor shown in FIG.

  A lower frame 7 is supported on the upper end of the balustrade 4 via a fixed support member 12. Specifically, a balustrade panel 4A having a lower end fixed to a support structure (not shown) is erected, and a fixing support member 12 is fitted into the upper end of the balustrade panel 4A and fixed by an adhesive or the like. , Located in the center of the lower frame 7. A bolt 13 having a lower portion fitted on the lower frame 7 side is inserted into a hole formed in the overlapping portion of the upper frame 6 and the lower frame 7 and is led out to the upper frame 6 side. The lower side of the cylindrical screw member 14 is screwed into the part. A screw 15 is screwed into the upper side of the cylindrical screw member 14 located in the upper frame 6 from above the guide guide 8.

  The fixed support member 12, the lower frame 7, and the upper frame 6 are coupled by tightening the cylindrical screw member 14 to the bolt 13, and the guide guide 8 is additionally coupled by tightening the screw 15 to the cylindrical screw member 14. The balustrade panel 4A, the fixed support member 12, the lower frame 7, the upper frame 6, and the guide guide 8 are firmly coupled to each other by this connecting structure portion.

  A plurality of fixed support members 12 used in the above-described connection structure portion are discretely arranged in the moving direction of the moving handrail 5 at a predetermined interval, for example, usually at an interval of 300 mm. Other members used in the above-described connecting structure portion are also arranged at predetermined intervals in accordance with the fixed support member 12. In contrast, unlike the fixed support member 12, the lower frame 7 and the upper frame 6 are configured continuously in the moving direction of the moving handrail 5.

  Therefore, between the adjacent fixed support members 12, there are discrete spaces where the above-described connecting structures are not arranged, and FIG. 2 is a cross-sectional view of that portion. In this discrete space, a heat insulating material 10 and a holding member 11 are arranged as shown in FIG.

  FIG. 5 is a perspective view showing the holding member 11.

  The holding member 11 is formed by bending a spring steel material, and an intermediate portion 16 that extends in the moving direction of the moving handrail 5 and is integrally coupled to both ends of the intermediate portion 16 so as to be orthogonal to the moving direction of the moving handrail 5. And a pair of folded portions 17A, 17B extending in the direction of the movement. The pair of folded portions 17A and 17B include holding portions 18A and 18B formed so as to hold a portion of the heat insulating material 10 curved along the shape of the heating body 9 from the lower side in the middle of the pair of folded portions 17A and 17B. In order to give moderate elasticity to the portions other than the holding portions 18A and 18B, the elasticity imparting portions 19A and 19B are provided.

  The holding member 11 having such a configuration is given elasticity between the pair of folded portions 17A and 17B, and the folded portions 17A and 17B are also given elasticity in a direction perpendicular to the moving direction of the moving handrail 5. Yes. When the holding member 11 is arranged in the lower frame 7 as shown in FIG. 2 taking advantage of this feature, the heating member 9 and the heat insulating material 10 are brought into pressure contact with the upper side of the inner surface of the lower frame 7 by elastic force. It can be firmly pressed against the lower frame 7 and held.

  However, as shown in FIG. 4, the heating body 9 cannot be disposed at the same position as in FIG. 2 where the fixed support members 12 are disposed at predetermined intervals in the moving direction of the moving handrail 5. Therefore, the heating body 9 at this position is bypassed to the side avoiding the fixed support member 12 as shown in FIG. In this portion, the position of the heating body 9 is changed, but the fixed support member 12 is not long in the moving direction of the moving handrail 5 and is arranged at a predetermined interval in the moving direction of the moving handrail 5. It can be easily held near the top surface inside the lower frame 7.

  In addition, it is conceivable to fix the heating element 9 in the lower frame 7 while covering the heating element 9 with the heat insulating material 10 at the place where the fixing support member 12 is disposed. Since the structure of the member 12 is restricted, the contact surface between the double-sided tape 10D of the heat insulating material 10 and the lower frame 7 and the fixed support member 12 becomes small. Therefore, in order to prevent that the heat insulating material 10 peels beforehand and the whole bends downward, the heat insulating material 10 is not provided in the said location in the lower frame 7. FIG.

  In the configuration of the passenger conveyor described above, it is not necessary to specially design the upper frame 6 and the lower frame 7 of the cold region specification, but the upper frame 6 and the lower frame 7 of the normal specification are used as they are, and the heating body 9, the heat insulating material 10, And it can be set as a cold district specification only by adding the holding member 11. For this reason, the upper frame 6 and the lower frame 7 can be used as standard products, and a passenger conveyor having a cold district specification that is simple and inexpensive with a small number of additional parts can be provided.

  In addition, the holding member 11 for holding the heating body 9 and the heat insulating material 10 is arranged at a predetermined interval in the moving direction of the moving handrail 5 and using the space where the fixed support member 12 is not arranged. The heating body 9 can be securely held at a position where the upper frame 6 can be effectively warmed. Then, when the upper side of the heating body 9 is in close contact with the inner surface of the lower frame 7, the heat of the heating body 9 is transmitted from the lower frame 7 to the upper frame 6. At this time, the lower part of the heating body 9 and the inner surface of the lower frame 7 are covered with the heat insulating material 10 so that the heat of the heating body 9 is prevented from escaping to the balustrade panel 4A side. can do. Thereby, the heat of the heating body 9 can be easily induced to the upper frame 6 side, and the heat of the heating body 9 can be prevented from being transmitted to the holding member 11.

  The upper frame 6 warmed in this way is in contact with or close to the entire moving handrail 5, can efficiently heat the entire moving handrail 5, and the heat insulating material 10 is added. As a result, the moving handrail 5 can be quickly warmed. In particular, the heat insulating material 10 is fixed to the inner surface of the lower frame 7 while covering the lower side of the heating body 9, and the upper side of the heating body 9 can be kept pressed against the inner surface of the lower frame 7. The positional deviation of the heating body 9 with respect to the frame 7 can be effectively prevented. Thereby, the stable heating effect with respect to the moving handrail 5 can be acquired.

  Therefore, even if it is a passenger conveyor installed in a cold region, the rubber component constituting the moving handrail 5 is cured and lacks flexibility when the moving handrail 5 is cooled and frozen when stopped at night or the like. In addition, the passenger conveyor can be operated smoothly even in the early morning, and the operating efficiency of the passenger conveyor can be improved.

  Further, since the heat insulating material 10 includes the double-sided tape 10D functioning as an adhesive layer on the surface side, the heat insulating material 10 can be easily fixed in the lower frame 7 by the double-sided tape 10D. Furthermore, if it is necessary to replace the heat insulating material 10 due to aging, it is only necessary to remove the double-sided tape 10D and reattach the new heat insulating material 10 to the inner surface of the lower frame 7, so that the heat insulating material 10 is replaced. Excellent convenience in work can be obtained.

  Moreover, since the heating body 9 is not held in the upper frame 6, the heating body 9 is not rubbed during the movement of the movable handrail 5, is not worn, and the heating body 9 is not disconnected. Moreover, since the holding member 11 is arranged at a predetermined interval in the moving direction of the moving handrail 5 using the space portion where the fixed support member 12 is not arranged, even when the passenger conveyor of the cold district specification is used, It is not necessary to change the structure of the upper frame 6, the lower frame 7, and the guide guide 8 from the normal specifications, and the heating body 9, the heat insulating material 10, and the holding member 11 can be easily attached. And since the heat insulating material 10 is attached to the part in which the fixed support member 12 is not arranged in the moving direction of the moving handrail 5, the entire heating body 9 is moved to the upper side of the inner surface of the lower frame 7 by the heat insulating material 10. By being supported, the downward bending due to the gravity of the heating body 9 can be reduced, and the adhesion between the lower frame 7 and the heating body 9 can be increased.

  Further, the holding member 11 used for holding the heating body 9 and the heat insulating material 10 has an intermediate portion 16 extending in the moving direction of the moving handrail 5 between the pair of folded portions 17A and 17B. It will not fall down. In other words, if the holding member 11 formed by only one folded portion 17A is disposed in the lower frame 7, the contact point with the lower frame 7 positioned relatively below the holding member 11 can be obtained without dropping downward. It is conceivable that the upper part of the holding member 11 rotates in the moving direction of the moving handrail 5 around the center. If such rotation of the holding member 11 occurs, the pressing force of the holding member 11 on the heating body 9 and the heat insulating material 10 decreases. However, when the pair of folded portions 17A and 17B having the intermediate portion 16 is formed, this rotation is prevented by the contact point between the pair of folded portions 17A and 17B and the lower frame 7, and the heating body 9 and the heat insulating material 10 are desirable. It can be securely held in position.

  6 is an AA cross-sectional view corresponding to FIG. 2 according to the second embodiment of the present invention.

  In FIG. 6, a U-shaped frame 23 formed so as to fit in the upper frame 6 is provided in the upper frame 6, and a guide guide for guiding the moving handrail 5 is provided at the upper end of the U-shaped frame 23. 8A is provided. A roller 21 is disposed on the U-shaped frame 23, and the rotating shaft 20 of the roller 21 is rotatably supported by an intermediate portion of the U-shaped frame 23. The outer peripheral surface of the roller 21 is in contact with the inner surface side of the moving handrail 5. For this reason, when the moving handrail 5 moves, the roller 21 rotates around the rotation shaft 20 to reduce the running resistance of the moving handrail 5.

  Also in FIG. 6, the holding member 11 shown in FIG. 5 is disposed in the lower frame 7 and is pressed against the top surface side of the lower frame 7 by an elastic force. Using this holding member 11, the heating body 9 and the heat insulating material 10 are firmly pressed against the lower frame 7 and held. Therefore, also in the second embodiment of the present invention, it is possible to obtain the same effects as those of the first embodiment described above. Since the other configurations of the second embodiment are the same as those of the first embodiment, the same reference numerals are given to the equivalents and the detailed description is omitted.

  7 is a cross-sectional view taken along the line BB corresponding to FIG. 4 according to the third embodiment of the present invention.

  A fixed support member 12 is fitted into the upper end portion of the balustrade panel 4A. In the fixed support member 12, bolts 24 whose heads are fitted to the fixed support member 12 on the lower frame 7 side are formed in overlapping portions of the lower frame 7, the upper frame 6, and the U-shaped frame 23, respectively. The nut 22 is inserted into the hole and led out to the U-shaped frame 23 side, and the nut 22 is screwed into the lead-out portion. The fixed support member 12, the lower frame 7, the upper frame 6, and the U-shaped frame 23 are coupled by a connecting structure portion by tightening the nut 22 to the bolt 24.

  A plurality of fixed support members 12 used in the above-described connecting structure portion are arranged at predetermined intervals in the moving direction of the moving handrail 5 as in the case of the previous embodiment. Other members used in the above-described connecting structure portion are also arranged at predetermined intervals in accordance with the fixed support member 12. In contrast, as shown in FIG. 6, there are discrete spaces between the adjacent fixed support members 12 in which the above-described connecting structure is not disposed. As shown in FIG. 6, the heating body 9, the heat insulating material 10, and the holding member 11 are arranged in the discrete space portions.

  As in the previous embodiment, the heating body 9 avoids the fixed support member 12 and bypasses the side thereof. In the same portion, the position of the heating body 9 is changed, but the fixed support member 12 is not large and is arranged discretely in the moving direction of the moving handrail 5, so that it is still near the top surface of the lower frame 7. Can be held in.

  Even with the passenger conveyor having such a configuration, the holding member 11 is arranged using a space portion in which the fixed support member 12 is not arranged at a predetermined interval in the moving direction of the moving handrail 5. The heating body 9 and the heat insulating material 10 can be firmly held at a position where the U-shaped frame 23 can be effectively heated. The heated upper frame 6 and U-shaped frame 23 are in contact with or close to the entire moving handrail 5 via the guide guide 8A, and efficiently heat the entire moving handrail 5. The moving handrail 5 can be quickly warmed by adding the heat insulating material 10. Therefore, even if it is a passenger conveyor installed in a cold region, the rubber component constituting the moving handrail 5 is cured and lacks flexibility when the moving handrail 5 is cooled and frozen when stopped at night or the like. In addition, the passenger conveyor can be operated smoothly even in the early morning, and the operating efficiency of the passenger conveyor can be improved.

  Moreover, since the heating body 9 is not held in the upper frame 6, the heating body 9 is not rubbed during the movement of the movable handrail 5, is not worn, and the heating body 9 is not disconnected. Therefore, also in the third embodiment of the present invention, the same effects as those of the first embodiment can be obtained. Since the other configurations of the third embodiment are the same as those of the first embodiment, the same reference numerals are given to the equivalents and detailed description thereof is omitted.

  8 is an AA cross-sectional view corresponding to FIG. 2 according to the fourth embodiment of the present invention, and FIG. 9 is a BB cross-sectional view corresponding to FIG. 4 according to the fourth embodiment of the present invention.

  As shown in FIG. 8, in the upper frame 6, heat insulating materials 31 to 33 are attached to the entire inner surface of the upper frame 6 along the moving direction of the moving handrail 5. Specifically, each of these heat insulating materials 31 to 33 has the same configuration as that of the first embodiment described above, and each of the heat insulating materials 31 and 32 is provided from both sides of the base piece 6C on the lower frame 7 in the upper frame 6. The heat insulating material 33 is fixed to the upper surface of the base piece 6C of the upper frame 6 with a double-sided tape and fixed to the inner surface of the pair of standing pieces 6A and 6B. .

  As shown in FIG. 9, the heat insulating material in the lower frame 7 is provided above the portion where the fixed support member 12 is disposed in the lower frame 7, that is, in the portion where the cylindrical screw member 14 is disposed in the upper frame 6. Similarly to 10, the heat insulating material 33 is not provided in order to avoid interference with the cylindrical screw member 14. On the other hand, since the heat insulating materials 31 and 32 do not interfere with the cylindrical screw member 14 because the standing pieces 6A and 6B of the upper frame 6 are arranged in parallel with the cylindrical screw member 14, the upper frame 6 It is also provided continuously at the place where the cylindrical screw member 14 is disposed.

  In the state where the inner surface of the upper frame 6 is covered with the heat insulating materials 31 to 33, when the heat of the heating body 9 is transferred from the lower frame 7 to the upper frame 6, the heat is transferred to the space inside the upper frame 6. Since escape can be prevented, smooth heat induction to the moving handrail 5 can be realized. Thereby, the whole moving handrail 5 can be warmed effectively. In particular, in the fourth embodiment of the present invention, the portion where the cylindrical screw member 14 is disposed in the upper frame 6 is also covered with the heat insulating materials 31 and 32, so that the heating effect of the entire moving handrail 5 is further enhanced. be able to. The other configurations of the fourth embodiment are the same as those of the first embodiment, and therefore, the same reference numerals are given to the equivalents and the detailed description is omitted.

  In addition, this invention is not limited to the Example mentioned above, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.

  Moreover, in Examples 1-4 of this invention, although the case where the heat insulating material 10 included the glass cloth 10B which forms a heat insulation layer was demonstrated, it is not restricted to this case, but the raw material which can deform | transform according to the shape of the heating body 9 If so, a material other than the glass cloth 10B may be applied to the heat insulating material. Furthermore, in the first to fourth embodiments of the present invention, the case where the heat insulating material 10 is adhered and fixed to the inner surface of the lower frame 7 using the double-sided tape 10D has been described. However, the present invention is not limited to this, and other means are used. The heat insulating material 10 may be fixed to the inner surface of the lower frame 7.

  Moreover, although Example 1-4 of this invention demonstrated the case where the holding member 11 was provided in the lower frame 7, and the heating body 9 and the heat insulating material 10 were pressed on the upper side among the inner surfaces of the lower frame 7, In addition to this case, the holding member 11 may not be used, and the heating body 9 and the heat insulating material 10 may be supported on the upper side of the inner surface of the lower frame 7 only by the double-sided tape 10D. Furthermore, although Example 4 of this invention demonstrated the case where the heat insulating materials 31-33 were attached to the whole inner surface of the upper frame 6, it is not restricted to this case, for example, the heat insulating materials 31-33 are the inner surfaces of the upper frame 6. You may attach only to a part of.
