Description

  The present invention relates to a shock absorber for stacking escalator steps used when one of the two steps is stacked on the other step.

  In general, when transporting escalator steps or storing them during maintenance, one of the two steps 10 and 20 is stacked on the other step 20 as shown in FIG. It is. That is, two steps 10 and 20 are stacked in two stages. Here, when the brackets 13 and 23 of the steps 10 and 20 are formed by aluminum die casting, even if the brackets 13 and 23 of the steps 10 and 20 are rubbed with each other, the durability of the steps 10 and 20 is achieved. The impact of is relatively small.

  On the other hand, when the brackets 13 and 23 of the steps 10 and 20 are made of, for example, steel, the brackets 13 and 23 rub against each other so that the rust-preventing coating applied to the surfaces of the brackets 13 and 23 is performed. May come off. As a result, the brackets 13 and 23 are liable to be deteriorated due to the generation of rust, and there is a problem that the durability of the steps 10 and 20 is lowered as compared with those made of aluminum die cast.

  Therefore, in the conventional escalator step stacking shock absorber, in order to avoid friction between the brackets 13 and 23, for example, a resin or the like between the brackets 13 and 23 of the two steps 10 and 20 stacked. A buffer member 100 made of an elastic body is interposed. Specifically, the buffer member 100 is disposed over substantially the entire region where the oblique sides 13c and 23c overlap in the vertical direction.

  Further, both end surfaces of the buffer member 100 in the longitudinal direction are in contact with the caps 15 and 25, respectively. Furthermore, as shown in FIG. 6, the buffer member 100 has a pair of fitting parts 100a and 100b. The fitting part 100a is fitted in the oblique side part 13c. The fitting part 100b is fitted in the oblique side part 23c.

  Therefore, the buffer member 100 is arranged in a state of being stretched between the caps 15 and 25, and the buffer member 100 restricts the movement of the step 10 in the tilt direction (the lower left side in FIG. 5). At the same time, since the fitting portions 100a and 100b are respectively fitted to the oblique sides 13c and 23c, the movement of the step 10 in the width direction is restricted. Therefore, the step 10 is supported from the step 20 by the buffer member 100 in a state where the brackets 13 and 23 are separated from each other.

  In addition, as a prior art regarding the step of the conventional escalator, there exists a thing as shown to patent document 1, for example.

JP 2009-67576 A

  In the conventional escalator step stacking shock absorber as described above, the cushioning member 100 is disposed over almost the entire region where the oblique sides 13c, 23c of the brackets 13, 23 overlap in the vertical direction. The size of the buffer member 100 was relatively large. Further, after the shipment from the factory in steps 10 and 20, a transportation cost is required to collect the buffer member 100 from the installation destination. Therefore, the used buffer member 100 may be discarded (disposable) at the installation site. In some cases, the member 100 could not be reused.

  Furthermore, in the conventional escalator step stacking shock absorber, the number of buffer members 100 used per escalator increases in proportion to the number of escalator steps. Accordingly, the resource loss related to the buffer member 100 has also increased.

  The present invention has been made to solve the above-described problems, and is used for stacking escalator steps that can save resources while preventing friction between brackets of steps in a stacked state. The purpose is to obtain a shock absorber.

The step-up shock absorber for an escalator according to the present invention includes a tread having a tread, a riser provided at one end in the depth direction of the tread and protruding rearward with respect to the tread, and a depth direction of the tread It has oblique sides which are arranged to extend inclined to the rear from the other end to the tread surface, respectively, and a pair of brackets provided on the widthwise ends of the rear surface of the tread surface of the tread plate, the pair Of the two steps, each of the brackets is provided with a pair of bases , each of which is provided so as to protrude outward in the width direction of the tread on the inclined tread side end of each of the oblique sides of the bracket. , Either one as the upper step, the other step on the lower step, the treads of each other in the opposite direction, and the front of the pair of brackets It is used when the hypotenuse parts are stacked so as to overlap each other in the vertical direction, and the hypotenuse parts of the two steps are provided in a region where the hypotenuse parts overlap in the vertical direction with an interval in the tilt direction. in a state that releases the oblique portions overlapping in the vertical direction in the step, the step of said upper, comprising a plurality of cushioning members supporting jointly steps of the lower part of the plurality of cushioning members The shock absorbing member is disposed in the upper end region in the inclination direction of the region where the oblique sides overlap in the vertical direction, and on the outer surface of the base of the upper step and the tip of the oblique side of the lower step.

As shown in FIG. 1, among the two steps 10 and 20, the treads 11a and 21a are opposite to each other, and the oblique sides 13c and 23c of the pair of brackets 13 and 23 are overlapped in the vertical direction. Step 10 is stacked on Step 20. A plurality of buffer members 30 are interposed between the two steps 10 and 20.

  The plurality of buffer members 30 are respectively disposed in both end regions in the inclination direction (upper right side and lower left end regions in FIG. 1) of the overlapping regions in the vertical direction of the oblique sides 13c and 23c. In FIG. 1, two buffer members 30 are shown, but two buffer members 30 are also provided between the oblique sides 13 c and 23 c on the back side of the paper surface of FIG. 1. That is, four buffer members 30 are interposed between step 10 and step 20.

  The buffer member 30 is formed of, for example, an elastic body such as resin (a material having a hardness lower than that of a steel material). As shown in FIGS. 2 and 3, the buffer member 30 is inclined with respect to the tip receiving portion 30a having an L-shaped cross section, a fitting portion 30b having a U-shaped cross section, and the upper and lower surfaces of the fitting portion 30b. And an inclined surface portion 30c. The L-shaped outer surface of the tip receiving portion 30a of the buffer member 30 shown in the upper right side of FIG. 1 is the end surface of the oblique side portion 13c of Step 10 that faces the oblique side portion 23c of Step 20, and the outer surface of the base 15 (on the driven roller 14 side). Touched surface). The L-shaped inner surface of the tip receiving portion 30 a is in contact with the tip portion of the oblique side portion 23 c of step 20.

  Further, the fitting portion 30b of the buffer member 30 shown in the upper right side of FIG. 1 is formed in a shape corresponding to the bent portion of the edge of the bracket 13, and the bent portion of the edge of the oblique side portion 13c of the bracket 13 is formed. It is mated. Furthermore, the inclined surface portion 30c shown on the upper right side in FIG. 1 is arranged so as to cover the opposite side of the bent portion of the edge of the bracket 13 (the back side of the paper in FIG. 1 and the L-shaped corner).

  Here, the buffer member 30 shown in the lower left side of FIG. 1, that is, the buffer member 30 arranged in the lower end region in the inclination direction of the region where the oblique sides overlap in the vertical direction, is also the buffer member 30 shown in the upper right side of FIG. 1. Similarly, it has the front-end | tip receiving part 30a, the fitting part 30b, and the inclined surface part 30c. The tip receiving portion 30 a of the buffer member 30 is in contact with the end surface of the oblique side portion 23 c of Step 20 that faces the oblique side portion 13 c of Step 10 and the outer surface of the base 25 (the surface directed toward the driven roller 24). The L-shaped inner surface of the tip receiving portion 30 a is in contact with the tip portion of the oblique side portion 13 c of Step 10.

  Further, the fitting portion 30b of the buffer member 30 shown in the lower left side of FIG. 1 is formed in a shape corresponding to the bent portion of the edge of the bracket 23, and the bent portion of the edge of the oblique side portion 23c of the bracket 23 is formed. It is mated. Furthermore, the inclined surface portion 30 c shown on the lower left side of FIG. 1 is arranged so as to cover the opposite side of the bent portion of the edge of the bracket 23.

Further, the tip end portion of the oblique side portion 13 c of the bracket 13 of Step 10 is supported from the outer surface of the base 25 of Step 20 via the buffer member 30. That is, the plurality of buffer members 30 support step 10 jointly from step 20 with the bracket 13 of step 10 and the bracket 23 of step 20 spaced from each other. Further, the displacement of the step 10 downward in the tilt direction is regulated by the plurality of buffer members 30.

  Here, the pair of driven rollers 14 are disposed so as to be adjacent to the outer surfaces of the pair of caps 25 (the front side or the back side in FIG. 1). At the same time, the pair of driven rollers 24 are disposed so as to be adjacent to the outer surfaces of the pair of caps 15 (the front side or the back side in FIG. 1). One of the pair of driven rollers 14 is in contact with one outer surface of the pair of bases 25, or one of the pair of driven rollers 24 is in contact with one outer surface of the pair of bases 15. Therefore, the displacement of the step 10 in the width direction is restricted.

  According to the step stacking shock absorber of the escalator of the first embodiment as described above, the step 10 is performed in the state where the plurality of buffer members 30 have separated the oblique sides 13c and 23c of the steps 10 and 20. Support from jointly. With this configuration, since the size of the buffer member 30 is smaller than that of the conventional buffer member 100, it is possible to save resources while preventing friction of the brackets 13 and 23 of the steps 10 and 20 in the stacked state. it can.

  In addition, since the size (thickness) of the buffer member 30 is smaller than that of the conventional buffer member 100, the height of the buffer member 30 when the step 10 is stacked on the step 20 is the same as that of the conventional buffer member 100. Compared to the case, it can be made smaller.

  Furthermore, since the structure of the buffer member 30 is simplified compared to the conventional buffer member 100 and the size of the buffer member 30 is reduced, the amount of raw materials and the manufacturing cost (for four) required for manufacturing the buffer member 30 are reduced. (Total) can be reduced as compared with the conventional buffer member 100 (total of two). In addition to this, the transportation cost when the used buffer member 30 is collected from the installation site can be reduced, and the reusability of the buffer member 30 can be improved.

  Further, the displacement of the step 10 downward in the tilt direction is regulated by the plurality of buffer members 30. At the same time, one of the pair of driven rollers 14 contacts one outer surface of the pair of bases 25, or one of the pair of driven rollers 24 is one outer surface of the pair of bases 15. The contact in the width direction of step 10 is regulated by contacting with. With this configuration, even when a plurality of buffer members 30 are used in place of the buffer member 100, the stability during transportation of steps 10 and 20 can be ensured, and the occurrence of load collapse can be suppressed. it can.

Here, in the conventional apparatus, since the size of the buffer member 100 is relatively large, the used buffer member 100 may interfere with the work during the installation work, and the used buffer member 100 may be cleaned up. It also took time to handle.
On the other hand, in the buffer device for stacking steps of the escalator of the first embodiment, the size of the buffer member 30 is smaller than that of the conventional buffer member 100, so that the buffer member 30 can be easily handled. The workability of installation can be improved.
