Description

TECHNICAL FIELD The present invention relates to a passenger conveyor skirt molding used for a railing of a passenger conveyor such as an escalator and a moving walkway.

A passenger conveyor for carrying passengers, such as an escalator, is constructed by incorporating a row of steps for carrying passengers into a truss installed in a building. A row of steps is formed by connecting a large number of steps in an endless manner, and balustrades are provided on both sides of the row of steps.

Each step of the escalator runs endlessly from the lower floor to the upper floor or from the upper floor to the lower floor, thereby conveying passengers from the lower floor to the upper floor or from the upper floor to the lower floor. On the side of the step, a skirt guard is provided substantially perpendicular to the step with a slight gap. The skirt guard is supported at its upper and lower parts via brackets extending from a balustrade fixing member fixed to the truss.

A balustrade panel is erected on the balustrade fixing member, and an inner deck is provided between the inner surface of the balustrade panel and the upper edge of the skirt guard so as to incline toward the step. there is The edge on the upper side of the inner deck is fixed to the inner surface of the balustrade panel via a joint member, and the lower side of the inner deck is formed with a bent portion protruding toward the step. The lower edge of the inner deck is superimposed over the skirt guard and screwed to the bracket.

Furthermore, a skirt molding is attached where the lower edge of the inner deck overlaps the skirt guard. This skirt molding is designed so that the screws that fix the bent part provided on the lower side of the inner deck to the skirt guard do not loosen during use and protrude to the step side and damage clothes etc. to cover the lower edge of the inner deck and the skirt guard fixing screws.

Further, the ends of the skirt molding are treated by attaching a cap having a cross-sectional shape similar to that of the skirt molding. The cap has a structure in which an insertion portion projecting from the cap is inserted into an insertion receiving portion recessed in the skirt molding. Furthermore, the inserting part of the cap has a built-in nut structure, and after inserting it into the skirt molding, it is fixed with a bolt.

The cap is molded and surfaced such that the shape of the tip and overall outer surface is smooth in the direction in which the surfaces of the inner deck and skirt guard extend. As a result, it is possible to prevent the clothes, etc., especially the hem of the clothes (hereinafter simply referred to as "clothes, etc.") from getting caught when getting on and off the passenger. However, in the case of the conventional configuration, as described above, the insertion portion of the cap has a nut structure, so the cap is fixed after being inserted into the skirt molding. Alternatively, the work of removing the bolt occurs when the removal is performed. In order to improve field work in a limited time, simplification of work is required.

Patent document 1 discloses a metal bat in which a resin cap is attached to the tip of the bat body via an adhesive.

JP-A-6-292746

The purpose of attaching a resin cap to the metal bat disclosed in Patent Document 1 is to reduce the high-pitched hitting sound of a hardball. Therefore, from the viewpoint of acoustic properties, it is essential to apply or fill the fitting surface with an adhesive. In this way, the work of attaching the resin cap to the metal bat is done efficiently until the completion of the assembly by using dedicated equipment in the factory where the optimum work environment is arranged, in order to prevent it from coming off with adhesive. be.

On the other hand, the operation of attaching the cap to the skirt molding for the passenger conveyor is carried out not in a fully equipped factory but on site where screws and the like are easily lost. In particular, regarding the work of replacing only the damaged cap, since the installation position is low near the floor and the worker is forced to have a cramped posture, it is desirable to make the work content easy to complete. rice field. The present invention has been made in view of such problems, and its object is to provide a passenger conveyor skirt molding end cap that does not require adhesives or bolts and can be easily installed or replaced on site. is to provide

In order to achieve the above object, the present invention provides a skirt molding end cap for a passenger conveyor, which is attached to both ends of a skirt molding, and has a cross-sectional contour adapted to the contour of the end face orthogonal to the longitudinal direction of the skirt molding. , a plurality of insertion parts that can be fitted corresponding to openings formed in the depth direction from the end surface of the skirt molding, and at least one of the plurality of insertion parts has the skirt molding attached to the inner side surface below the balustrade. It is a claw-shaped insertion portion that is inserted from the end face into the formed internal space. and a protrusion projecting in a direction away from the skirt molding and fitted and locked in a cap fixing hole formed in the skirt molding.

ADVANTAGE OF THE INVENTION According to the present invention, it is possible to provide a passenger conveyor skirt molding end cap that does not require adhesives or bolts and can be easily installed or replaced on site.

2A and 2B are two different perspective views of a passenger conveyor skirt molding end cap (hereinafter also simply referred to as a "cap") according to an embodiment of the present invention; FIG. FIG. 2 is a four-sided view of the cap of FIG. 1, showing the top, front, proximal end, and distal end. 1. It is a perspective view which shows the state of three steps before and behind attaching the cap of FIG. 1 to the skirt molding for passenger conveyors (it is only hereafter also called "skirt molding"). It is sectional drawing which orthogonally crosses the longitudinal direction in the state which attached the cap of FIG. 1 to the skirt molding, and also clearly shows the positional relationship with an inner deck and a skirt guard.

Hereinafter, a passenger conveyor skirt molding end cap according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a cap according to an embodiment of the present invention viewed from two different viewpoints with respect to the insertion direction. Note that the fitting direction substantially coincides with the longitudinal direction of the skirt molding. FIG. 2 is a four-sided view of the top, front, proximal end, and distal end of the cap of FIG. That is, of the six views, four views showing the cap from four directions excluding the bottom and the back are shown.

1 and 2, the cap 1 has a similar cross-sectional shape adapted to the cross-sectional shape of the skirt molding 5. As shown in FIG. Therefore, the two are tightly fitted. However, if the fitting is misaligned in the cross-sectional direction, the edges 1f and 5f (see FIG. 3) of the end faces are slightly exposed. In particular, in order to smooth the edge 5f of the end face of the skirt molding 5, it is preferable that the end face of the skirt molding 5 is chamfered by about 0.3 mm. By this chamfering, it is possible to prevent a problem that the passenger's clothing or the like is caught. After chamfering, the contact plane becomes smaller than the original outer shape. It is preferable to reduce the cross-sectional shape of the cap 1 in the range of 0.3 mm to 0.5 mm in accordance with the reduced cross-sectional shape of the skirt molding 5 .

As shown in FIGS. 1 and 2, three types of insertion portions 2 to 4 are provided from the end face of the cap 1. FIG. The insertion portion 2 has a locking claw 2b that constitutes the major part thereof, and a convex portion 2a for preventing the cap 1 from coming off or coming off when it is inserted into the skirt molding 5. The locking claw 2b is flat. It protrudes from the face toward the front. The convex portion 2 a is fitted and engaged with a cap fixing hole 5 a provided in the skirt molding 5 . The locking claw 2b has an inserting direction, that is, a longitudinal direction parallel to the lower inner surface of the balustrade, and has a plate-like shape elongated in the insertion direction and has elasticity in the front and depth directions. The elasticity is derived from the fact that the material of the cap 1 is resin or metal.

Since the insertion part 2 and the cap fixing hole 5a are visible from the front of the outside, the insertion part 3 has the effect of hiding the cap fixing hole 5a. Furthermore, in order to prevent the passenger's clothing from being caught, the structure is tapered toward the skirt molding 5 side, that is, the tip is tapered to a rounded shape. The main purpose of the cap 1 is to attach it to both ends of the skirt molding 5 to smooth the edges 5f of both ends.

However, the cap 1 itself for that purpose can also cause catching. Therefore, as described above, the insertion portion 3, which is likely to have such a problem, is tapered toward the skirt molding 5 to smoothen the portion. The insertion part 4 is inserted into an insertion receiving part 5e provided in the skirt molding 5, and has a structure to maintain the fitting strength.

Next, the process of attaching the cap 1 to the skirt molding 5 will be described with reference to FIGS. 3 and 4. FIG. 3A and 3B are perspective views showing three stages before and after attaching the cap 1 of FIG. 1 to the skirt molding 5. FIG. FIG. 4 is a cross-sectional view orthogonal to the longitudinal direction of the state in which the cap 1 of FIG. 1 is attached to the skirt molding 5, and also clearly shows the positional relationship between the inner deck and the skirt guard.

As shown in FIG. 3, skirt molding fixing holes 5b are provided at regular intervals. As shown in FIG. 4, the skirt molding 5 is bolted to the lower inner surface of the balustrade. That is, the skirt molding 5 is screwed on the lower inner surface of the balustrade where the lower edge of the inner deck 6 and the skirt guard 7 overlap. Thus, it is necessary to attach the cap 1 to the skirt molding 5 before the skirt molding 5 is secured. However, only the cap 1 can be damaged and replaced by loosening the setscrew and floating it from the lower inner surface of the balustrade without removing the skirt molding 5. - 特許庁

Attachment of the cap 1 is as follows. The inserting portion 2 of the cap 1 is inserted into the inner concave portion 5c of the skirt molding. Next, the insertion part 2 is inserted in the fixing direction of the skirt molding 5 while being bent. At this time, the protrusion 2a is hooked to the cap fixing hole 5a drilled at the end of the skirt molding 5. As shown in FIG. At the same time, the cap insertion part 3 is inserted into the skirt molding opening 5d. At the same time, the insertion portion 4 is inserted into the skirt molding insertion receiving portion 5e. Incidentally, as described above, the cap 1 can be removed by reversing the procedure by appropriately loosening the setscrew.

FIG. 4 shows the skirt molding 5 with the cap 1 attached to the inner deck 6 and the skirt guard 7 in the completed installation state. In this completed state, it is preferable that the height 9 of the projection 2a is larger than the gap 8 between the surface of the inner deck 6 and the facing surface of the insertion portion 2. As shown in FIG. In this configuration, even if the gap 8 becomes zero due to deformation or the like, the locked state is maintained by the height 9 which is originally larger than the gap 8, so the projection 2a does not come off the cap fixing hole 5a.

The reason for providing the gap 8 is to provide a margin for error absorption even if the flat surface of the lower inner side surface of the balustrade has some undulations. That is, as shown in FIG. 3, the skirt molding fixing holes 5b provided at regular intervals are screwed with an appropriate tightening strength so that the gap between the lower inner surface of the balustrade and the skirt molding 5 is not visible from the plane. error should be absorbed.

The passenger conveyor cap 1 according to the embodiment of the present invention can be summarized as follows.
[1] The passenger conveyor cap 1 is attached to both ends of the skirt molding 5 to smooth the edges 5f of both ends. The skirt molding 5 is attached to the lower inner surface of the balustrade of the passenger conveyor with its longitudinal direction aligned with the conveying direction of the passenger conveyor. The cap 1 has a cross-sectional contour adapted to and similar to the contour of the end face perpendicular to the longitudinal direction of the skirt molding 5 .

Further, the cap 1 is provided with a plurality of inserting portions 2 to 4 in order to be inserted into and fixed to the end surface of the skirt molding 5. As shown in FIG. A plurality of openings having a depth in the depth direction are formed in the end face of the skirt molding 5 so as to correspond to these insertion portions 2 to 4 . This has a fitting structure in which the insertion parts 2 to 4 can be fitted into a plurality of openings.

At least one of the plurality of inserting portions 2 to 4 is a claw-shaped inserting portion 2 . The claw-shaped insertion part 2 is inserted into the inner space from the end face of the skirt molding 5 to attach and fix the cap 1 to the skirt molding 5 . The internal space referred to here is an internal space formed by a partition provided in the gutter-shaped space by installing the gutter-shaped skirt molding 5 on the lower inner surface of the balustrade. This internal space is defined by a mold used for draw-molding the aluminum die-cast skirt molding 5 .

The claw-shaped insertion portion 2 has a locking claw 2b and a convex portion 2a, which are the major part thereof. The engaging claw 2b has its insertion direction, that is, the longitudinal direction, parallel to the lower inner surface of the balustrade. do. The projecting portion 2a protrudes from the locking claw 2b in a direction perpendicular to the lower inner surface of the balustrade, and is fitted and locked into a cap fixing hole 5a formed in the skirt molding 5. As shown in FIG.

The skirt molding 5 is, for example, a kind of safety function for preventing catching of clothes, etc., which is likely to occur between an automatically ascending/descending stair-like tread (steps not shown) and the balustrade. The skirt molding 5 can prevent clothes and the like from being caught by attaching a metal belt-shaped member cut out to a required length from a standard material to a portion requiring protection on the lower inner surface of the balustrade. The term "protected portion" as used herein refers to a portion that requires countermeasures against catching.

Before and after the operation of attaching the skirt molding 5 to the lower inner surface of the balustrade, the operation of attaching the cap 1 is carried out not in a fully equipped factory but on site where screws and the like are easily lost. In particular, regarding the work of replacing only the damaged cap 1, since the installation position is low near the floor surface and the worker is forced to take a cramped posture, it is desirable to make the work content easy to complete. was

Both ends of the skirt molding 5 are cut at an angle perpendicular to the longitudinal direction and processed to a required length for use. Therefore, both ends of the skirt molding 5 are formed with edges 5f equivalent to cutlery. In order to prevent danger to the user due to exposure of this edge 5f, the cap 1 is attached to both ends of the skirt molding 5 and smoothed. Mainly, the danger is that the edge 5f is caught by clothing or the like, and that the edge 5f directly or indirectly injures the user. Since the edge 1f on the cap 1 side may also get caught on clothes or the like, countermeasures are also shown in [4] below.

The cap 1 is attached to the cap fixing hole 5a formed in the skirt molding 5 by simply fitting the insertion portions 2, 4, etc. to the tubular insertion receiving portion 5e and the like opened in the end face of the skirt molding 5. A projection 2a formed on the 2 is fitted and locked. Since this fitting structure does not require bolt fixing, adhesive application or filling, on-site installation or replacement work can be simplified. Moreover, it is possible to suppress the displacement in the longitudinal direction and in the direction perpendicular to it, so that it is difficult to come off.

[2] In the cap 1 of [1] above, the insertion is formed in a positional relationship and a size that can hide the cap fixing hole 5a of the skirt molding 5 provided for fitting with the claw-shaped insertion portion 2. It has part 3. The insertion part 3 has a tapered shape in which the outer cross-sectional shape tapers off as it goes away from the joining surface with the skirt molding 5 to the end.

According to this, the insertion part 3 formed as one component of the fitting mechanism has a fitting function, an aesthetic appearance that hides the cap fixing hole 5a, and avoids troubles such as catching the user's clothes or the like. and can be made compatible. The cap 1 can thus ensure good functioning.

[3] The lower inner surface of the balustrade is formed by at least one of the inner deck 6 and the scard guard 7 . For example, the skirt molding 5 is fixed by bolts to the overlapped surface of the inner deck 6 covering the skirt guard 7 constituting the vertical wall surface like a roof. When the cap 1 of [1] is attached to the end of the skirt molding 5 and is fixed to the inner deck 6 and the skirt guard 7, the locking claws 2b and the projections 2a and 2b on the surface of the inner deck 6 are fixed to the inner deck 6 and skirt guard 7. It is preferable that the height 9 of the convex portion 2a is larger than the gap 8 between the facing surfaces of the insertion portion 2 having the portion 2a.

According to this, even when the cap 1 moves in the direction to completely fill the gap 8, the height (thickness) 9 of the convex portion 2a is larger than that of the cap with which the convex portion 2a is engaged. It does not come off from the fixing hole 5a. Therefore, after the skirt molding 5 with the cap 1 is fixed to the lower inner surface of the balustrade, it is possible to prevent the cap 1 alone from coming off from the skirt molding 5. - 特許庁

[4] The cap 1 of [1] above preferably has a cross-sectional outer shape smaller than that of the skirt molding 5 by 0.3 to 0.5 mm. The reason for the reduction is that, if the edge 5f of the end face perpendicular to the longitudinal direction of the skirt molding 5 is chamfered, it is adapted to the outer shape smaller than the original outer shape due to the chamfering.

Even if two surfaces with the same cross-sectional outline are brought into close contact, if there is a deviation in the direction parallel to the cross-section, even a slight deviation will cause the edge 5f to appear and the effect of burrs will inevitably occur. It may cause the cap 1 to be damaged or come off due to being caught or the like. Such problems can also be prevented by avoiding the adverse effects of the edge 5f and burrs.
