And an inner piece 17 disposed on the dry portion 4 side. A claw portion 18 is bent at the tip edge of the outer piece 16. The claw portion 18 is provided so as to be hooked on a corner portion inside the collar-shaped portion 13. The right clip guide 15a is formed in the same manner as the left clip guide 15b except that the positional relationship in the left-right direction is reversed. Hereinafter, the left and right clip guides 15a and 15b are collectively referred to as the clip guide 15.

  Such a clip guide 15 is attached to the collar-like portions 13 on both the left and right sides of the guide rail 11 as shown in FIG. The moving handrail 5 is attached to the guide rail 11 so as to wrap the left and right collar-like portions 13 via the clip guide 15.

  Further, in the free state in which the clip guide 15 is detached from the guide rail 11 as shown in FIG. 3, the tip of the inner piece 17 of the clip guide 15 approaches the inner surface of the outer piece 16 by its own elastic force. Thereby, when the worker attaches the clip guide 15 to the guide rail 11 when installing the escalator 1 or during maintenance inspection, the worker has a large space between the outer piece 16 and the inner piece 17 of the clip guide 15. The clip guide 15 needs to be elastically deformed so as to be spread by force. Then, the collar portion 13 of the guide rail 11 is fitted into the clip guide 15 in a state where the space between the outer piece 16 and the inner piece 17 is widened. In the conventional work, the worker performs such work only with his / her hand, and the direction in which the collar portion 13 is fitted inside the clip guide 15 and the force between the outer piece 16 and the inner piece 17. You need both the power to move to. Thereby, the assembling work is difficult. According to the clip guide mounting jig 20 of this embodiment, it is possible to improve the assembly workability and shorten the work time.

  FIG. 4 is a perspective view of the clip guide mounting jig 20. FIG. 5 is an exploded perspective view of FIG. FIG. 6 is a view of the rail holding member 21 of the clip guide mounting jig 20 as viewed from above. 7 is a view of the rail holding member 21 as viewed from the left side of FIG. The clip guide mounting jig 20 accommodates the long guide rail 11 shown in FIG. 3 inside, and a clip guide 15 interposed between the guide rail 11 (FIG. 2) and the moving handrail 5 (FIG. 2).

Used to attach the guide 15. Hereinafter, the clip guide mounting jig 20 is referred to as a mounting jig 20.

  The mounting jig 20 includes a rail holding member 21 and a guide member 31. The rail holding member 21 and the guide member 31 are integrally coupled. As shown in FIGS. 5 to 7, the rail holding member 21 includes a rail holding portion 22 and a grip portion 25 coupled to the rail holding portion 22. The rail holding portion 22 is a long portion having a long and narrow upper plate portion 22a and a lower plate portion 22b that are parallel to each other and a connecting portion 22c that connects one end in the width direction (the right end in FIG. 5). As a result, the cross section becomes U-shaped, and a rail fitting groove 22d is formed in the rail holding portion 22 over the entire length at the other end in the width direction (the other end in FIG. 5). Since the rail holding portion 22 of the mounting jig 20 extends in the longitudinal direction of the guide rail, the width direction corresponds to the left-right direction of the escalator 1 (FIG. 1) when the clip guide 15 is mounted. The rail fitting groove 22d can be fitted into the end portion in the width direction of the collar portion 13 of the guide rail 11. Both ends of the rail fitting groove 22d in the longitudinal direction are opened at both ends of the rail holding portion 22 in the longitudinal direction. The cross-sectional shape of the plane perpendicular to the longitudinal direction of the rail fitting groove 22d is substantially rectangular.

The insertion portion 24 has a substantially triangular cross-sectional shape with respect to a plane orthogonal to the longitudinal direction. Specifically, as shown in FIG. 13 to be described later, the insertion portion 24 has a tapered shape in which the thickness decreases toward one end in the width direction (the right end in FIG. 13). Further, the lower side surface of the distal end portion (the right end portion in FIG. 3) of the insertion portion 24 has a curved surface shape that is an arc shape that swells downward, and the lower side surface of the rail fitting groove 22d that is continuous therewith is the upper side. It has a curved surface that is recessed. The upper side surface of the rail holding part 22 is a flat surface. The insertion portion 24 can be inserted inside the clip guide 15. The shape of the insertion portion 24 is not limited to the shape shown in FIG. 13, and the lower surface may be a flat surface inclined with respect to the upper surface, or the curved surface shape in which the lower surface of the tip portion is recessed upward in FIG. 13. It may be.

  The grip portion 25 is a columnar portion that is coupled so as to protrude upward, which is a direction orthogonal to the longitudinal direction, on the upper surface of one end portion in the longitudinal direction of the rail holding portion 22 (front end portion in FIG. 5). is there. The base portion of the grip portion 25 has a smaller diameter than other portions of the grip portion 25. As will be described later, the grip portion 25 is a portion that can be gripped with one hand when the operator holds and moves the mounting jig 20.

  Of the rail holding member 21, the rail holding portion 22 is formed of a metal material such as a stainless alloy. The grip portion 25 includes a shaft portion 26 having the same diameter in the entire axial direction, and a cylindrical portion 27 that is fitted and fixed to the outside from the tip portion to the intermediate portion of the shaft portion 26. A shaft portion 26 that is disengaged from the cylindrical portion 27 in the grip portion 25 serves as a root portion having a reduced diameter. In this configuration, the shaft portion 26 is formed from a metal material such as a stainless alloy, and the cylindrical portion is formed from a resin material such as urethane rubber. The grip portion 25 can be fixed to the rail holding portion 22 by welding or screw connection. When screwing the grip portion 25 and the rail holding portion 22, a male screw portion is formed at the base portion of the grip portion 25, and the male screw portion is screwed to a screw hole formed in the rail holding portion 22.

  FIG. 8 is a view of the guide member 31 of the mounting jig 20 as viewed from above. FIG. 9 is a view of the guide member 31 as viewed from the left side of FIG. FIG. 10 is a view of the guide member 31 as viewed from the right side of FIG.

  The guide member 31 is coupled to the rail holding portion 22 of the rail holding member 21 via the grip portion 25. The guide member 31 corresponds to a guide element. The guide member 31 includes a fitting portion 32 and a guide main body portion 36, and the fitting portion 32 and the guide main body portion 36 are integrally coupled. The fitting portion 32 is fitted and fixed to the root portion of the grip portion 25 (FIG. 5) having a reduced diameter. Specifically, the fitting part 32 has a hollow cylindrical shape as a whole, and is divided in a part in the circumferential direction in the center direction of the cylinder, and both end parts in the circumferential direction are formed here. And the protrusion 34 which protrudes to a radial direction outer side is formed in the circumferential direction both ends. When the fitting portion 32 is fixed to the base portion of the grip portion 25, the fitting portion 32 is elastically deformed so that both ends in the circumferential direction are separated, and the fitting portion 32 is fitted to the root portion in this state. Then, both end portions in the circumferential direction of the fitting portion 32 are brought close to each other so that the diameter of the fitting portion 32 is reduced, and further, both end portions in the circumferential direction are joined by screwing screws 35 to the respective projecting portions 34. A gap may be formed between both edges in the circumferential direction of the fitting portion 32 in a state where the two protrusions 34 are coupled by the screw 35. Further, instead of the screw 35, a pin that does not have a thread portion may be used, and the two protrusions 34 may be coupled by passing the pin through the two protrusions 34 by tight fitting.

  The guide main body 36 is a cylindrical portion having a hole 37 inside and a rectangular cross-sectional shape. The guide body portion 36 is coupled to the opposite side of the protrusion 34 on the outer peripheral surface of the fitting portion 32 via a plate-like connecting portion 38. The guide main body portion 36 is inclined with respect to the fitting portion 32 by being connected to one end of the connecting portion 38 (the lower end in FIG. 8 and the right end in FIG. 9) in a downwardly inclined state. The width W (FIG. 9) of the hole 37 of the guide main body 36 increases from one end (left end in FIG. 9) to the other end (right end in FIG. 9). This width W is the entire axial direction. It may be the same. The fitting part 32, the connecting part 38, and the guide main body part 36 of the guide member 31 are formed of a metal material such as a stainless alloy, for example.

  As shown in FIG. 4 and FIG. 11 described later, the clip guide 15 is movably inserted into the hole 37 of the guide main body 36. The hole portion 37 restricts the portion of the clip guide 15 that moves toward the rail holding portion 22 so as to be positioned in the vicinity of the rail holding portion 22. Thereby, as will be described later, the insertion portion 24 of the rail holding member 21 can be easily inserted into the rear side portion of the clip guide 15. For this reason, when attaching the clip guide 15 to the guide rail 11, it is possible to improve the attachment workability. In this specification, the rear side is the rear side (upper left side in FIG. 4) in the movement direction (δ direction in FIGS. 4 and 11) when the operator moves the mounting jig 20 along the guide rail 11. , The upper side of FIG. The front side refers to the front side in this moving direction (the lower right side in FIG. 4 and the lower side in FIG. 11).

  Next, using such a mounting jig 20, a clip guide is formed on a portion of the collar-shaped portion 13 of the guide rail 11 corresponding to the forward path side portion 5 a of the moving handrail 5 and extending linearly along the longitudinal direction. The operation of attaching 15 will be described. FIG. 11 is a view of a state in which the clip guide 15 is attached to the guide rail 11 using the attachment jig 20 as viewed in a direction perpendicular to the upper surface of the guide portion 10, for example, in the direction of arrow β in FIG. 12 is a cross-sectional view taken along the line BB in FIG. 13 is a cross-sectional view taken along the line CC of FIG. 11 with the clip guide 15 omitted. 14, FIG. 15, and FIG. 16 show a DD sectional view, an EE sectional view, and an FF sectional view of FIG. 11, respectively.

  When the clip guide 15 is attached, the first step is first performed. In the first step, the clip guide 15 is passed through the hole 37 of the guide member 31 of the mounting jig 20, the insertion portion 24 of the mounting jig 20 is inserted inside the clip guide 15, and the straight line of the guide rail 11 is used. The collar-like portion 13 extending in a shape is fitted into the rail fitting groove 22d.

  In the first step, for example, after passing the clip guide 15 through the hole 37 of the guide member 31 from the upper side to the lower side, a part of the clip guide 15 behind the guide member 31 (upper part in FIG. 11). The insertion part 24 of the mounting jig 20 is inserted into the inner side of. In this state, as shown in FIGS. 12 and 13, a part of the linear portion in the longitudinal direction of the collar portion 13 of the guide rail 11 is fitted into the rail fitting groove 22 d of the mounting jig 20. At this time, as shown in FIG. 13, it is preferable that the collar portion 13 is sufficiently inserted to the far end of the rail fitting groove 22d. Further, in this state, as shown in FIGS. 14 and 15, the insertion portion 24 moves from the position shown in FIG. 14 toward the position shown in FIG. 15 is gradually inserted inside. Along with this, the space between the outer piece 16 and the inner piece 17 of the clip guide 15 gradually increases toward the rear side. In the state shown in FIG. 15, the claw portion 18 of the clip guide 15 is hooked on the distal end portion of the mounting jig 20. The length of the outer piece 16 of the clip guide 15 is shortened, and the tip of the claw portion 18 of the clip guide 15 is not caught by the tip of the fixture 20 at a position corresponding to FIG. It may be arranged on the upper side.

  In this state, as shown in FIG. 11, the rear portion of the clip guide 15 that has passed through the hole 37 of the guide member 31 is twisted from the lower side to the upper side, and the mounting jig 20 is placed inside the clip guide 15. The insertion part 24 is inserted.

  In the first step, the clip guide 15 may be passed through the hole 37 of the guide member 31 after a part in the longitudinal direction of the collar portion 13 of the guide rail 11 is fitted in the rail fitting groove 22d of the mounting jig 20. . Then, the insertion portion 24 of the attachment jig 20 may be inserted into the clip guide 15 inside the rear portion of the guide member 31.

  Next, a second step is performed in which a portion of the collar portion 13 of the guide rail 11 that is detached from the rear side that is one end side in the longitudinal direction with respect to the mounting jig 20 is fitted into the clip guide 15. In this second step, the operator applies a force by hand so as to widen the space between the outer piece 16 and the inner piece 17 of the clip guide 15 to elastically deform the clip guide 15. Then, the collar-like portion 13 is fitted into the clip guide 15 like the portion surrounded by the one-dot chain line P in FIG. As described above, only a part of the clip guide 15 is manually guided inward by an operator in advance before the guide rail 11 is fitted into the other part of the clip guide 15 using the mounting jig 20 as will be described later. 11 is inserted.

  Next, the third step is performed. In the third step, the operator holds the grip portion 25 of the mounting jig 20 with one hand (for example, the left hand). Then, with the other hand (for example, the right hand), a force is applied so that a portion of the clip guide 15 located behind the mounting jig 20 is directed toward the guide rail 11 (arrow γ side in FIG. 11). Then, while pressing the portion of the clip guide 15 located behind the mounting jig 20 against the collar-shaped portion 13 of the guide rail 11, the mounting jig is moved along the longitudinal direction of the guide rail 11 with the arrows in FIGS. 11 and 12. Move in the δ direction. At this time, the mounting jig 20 moves with respect to the clip guide 15 with the guide member 31 in front. As a result, the clip guide 15 is gradually fitted into the collar portion 13 of the guide rail 11 along the longitudinal direction. At this time, for example, in the portion surrounded by the one-dot chain line Q in FIG. 11, the space between the outer piece 16 and the inner piece 17 is widened by the mounting jig 20 in the clip guide 15 as shown in FIG. 15. For this reason, while moving the mounting jig 20 in the direction of the arrow δ in FIGS. 11 and 12, just by pushing the rear portion of the clip guide 15 from the mounting guide 20 toward the guide rail 11 with the other hand, The collar portion 13 can be easily fitted into the pressed portion of the clip guide 15. Then, the collar portion 13 is gradually fitted into the clip guide 15 along the longitudinal direction.

  In addition, since the collar-shaped part 13 is changing rapidly in the curve vicinity in the vicinity of the entrance 8 of the upper and lower sides of the guide rail 11, the clip guide 15 is attached to the collar-shaped part 13 using the attachment jig 20 in that part. It is not possible. For this reason, the operator attaches the clip guide 15 by hand to the curved collar portion 13 by a conventional method.

  According to the mounting jig 20 and the mounting method of the clip guide 15 using the mounting jig 20, the mounting work at the time of mounting the clip guide 15 can be easily performed, so that the working time can be shortened and the workability can be improved. Improvements can be made.

  FIG. 17 is a view corresponding to FIG. 14 illustrating a state in which the clip guide 15 is attached to the guide rail 11 in the attachment method of the clip guide 15 of the comparative example. In this comparative example, the clip guide 15 is attached to the collar-like portion 13 of the guide rail 11 over the entire length in the longitudinal direction by using only the hand without using the attachment jig 20 (FIG. 4). At this time, as shown in FIG. 17, since the tip of the inner piece 17 of the clip guide 15 approaches the inner surface of the outer piece 16 by its own elastic force, when the collar portion 13 is fitted inside, the outer piece It is necessary to fit the collar-like portion 13 while expanding the space between 16 and the inner piece 17 with a large force. Performing this fitting operation over the entire length in the longitudinal direction of the clip guide 15 requires excessive labor and requires a long time for the operation. Thereby, in the attachment method of a comparative example, shortening of work time is desired. Moreover, when attaching a clip guide in the escalator installed in the railway station, the request | requirement with respect to shortening of working time is especially large. In the embodiment, the work of expanding the space between the outer piece 16 and the inner piece 17 of the clip guide 15 by the operator's hand can be greatly reduced. Thereby, since the attachment work of the clip guide 15 can be performed easily, the time of attachment work can be shortened. For this reason, it can respond to said request. When the mounting jig 20 is moved along the guide rail 11, the operator may move while descending the step 3 (FIG. 1) while the escalator 1 is stopped. May be.

  In addition, since the grip portion 25 is coupled to the upper side surface of the mounting jig 20, the operator can easily carry out the movement with the mounting jig 20. Although the case where the grip portion 25 is columnar has been described above, the shape of the grip portion 25 is not limited to such a shape. For example, the grip portion is U-shaped and both ends of the grip portion are rails of the mounting jig 20. It is good also as a structure couple | bonded with the upper surface of the holding | maintenance part 22. FIG. Moreover, it is good also as a structure couple | bonded so that the block-shaped grip part may protrude in the upper surface of the rail holding part 22 of the attachment jig 20. FIG. Further, the mounting jig 20 may be configured not to have a gripping portion protruding from the upper side surface of the rail holding portion 22. When this configuration is used, for example, when the attachment jig is moved, the upper portion of the rail holding portion 22 may be grasped and moved.

  FIG. 18 is a view corresponding to FIG. 11 showing two examples of the guide member 31 of the mounting jig 20. In FIG. 18A, the direction of the hole 37 of the guide member 31 is inclined with respect to the longitudinal direction of the mounting jig 20 when viewed in a direction perpendicular to the upper side surface of the rail holding section 22 of the mounting jig 20. As described above, the guide member 31 is coupled to the rail holding member 21. When this mounting jig 20 is used, unlike the configuration shown in FIG. 11, the amount of twist of the clip guide 15 that has passed through the hole 37 of the guide member 31 is reduced, and the mounting jig 20 is mounted inside the clip guide 15. The insertion portion 24 of the jig 20 can be inserted.

  In FIG. 18B, the position of the hole 37 of the guide member 31 is shifted to the side opposite to the guide rail 11 in the width direction with respect to the center O in the width direction of the rail holding member 21 (right side in FIG. 18B). The guide member 31 is coupled to the rail holding member 21. The hole portion 37 of the guide member 31 faces substantially in the front-rear direction (vertical direction in FIG. 18B) when viewed in a direction perpendicular to the upper side surface of the rail holding portion 22 of the mounting jig 20. In such a configuration, the twist amount of the clip guide 15 that has passed through the hole portion 37 of the guide member 31 can be reduced, and the insertion portion 24 of the mounting jig 20 can be inserted into the clip guide 15.

  Further, the shapes of the guide main body 36 and the hole 37 of the guide member 31 in the mounting jig 20 are not limited to the configurations of the above examples. For example, as shown in FIG. 19, both ends in the longitudinal direction (left-right direction in FIG. 19) of the hole 37 of the guide main body 36 may have a shape in which the inner peripheral surface protrudes in an arc shape inside. In such a configuration, the clip guide 15 passing through the hole 37 is easily inclined in the hole 37. In addition, although illustration is abbreviate | omitted, the shape of the guide main-body part 36 and the hole part 37 is good also as an ellipse or a rhombus, respectively.

  In the above description, the case where the guide element of the mounting jig 20 is the guide member 31 which is a separate member from the rail holding member 21 including the rail holding part 22 has been described. However, the guide element and the main body part are one member. May be integrally formed. Moreover, although the case where the clip guide mounting jig has a guide element such as the guide member 31 has been described above, the clip guide mounting jig may not have the guide element.
