Description

[Detailed Description of the Invention] The present invention relates to an escalator that also prevents leakage of backflowing oil caused by capillary action.

Recently, the use of escalators has shifted from being used as a means of vertical transportation for functional ice storage, to using escalators with their functional and elegant balustrade structures to match interior decoration.

For this reason, the exterior panels that cover the truss of escalators come in a wide variety of colors, patterns, materials, etc., depending on the wishes of escalator users.

By the way, as shown in FIG. 1, the conventional escalator running device consists of a driving wheel 1, a left and right endless chain 3 that is moving around a driven wheel, a front step wheel 4, and a rear wheel attached to a step 5 attached to the driving wheel 1. The endless chain 3, the front step wheels 4, and the rear wheels 6 require sufficient oiling in order to run smoothly. .

However, the oil pan 8 that receives this supplied oil
As shown in Figure 2, the pieces are divided into multiple pieces, and they are overlapped one after another with a certain amount of lap allowance (indicated by A in the figure) from the IN side, and then welded at two or more appropriate locations. However, oil may ooze out onto the exterior plate 9 from the wrapped area due to capillary action, detracting from its beauty as a decorative item, and if there is a large amount of oil leaking, the user may This may stain the clothes or cause discomfort to the user due to the smell of oil.

Reference numeral 10 in FIG. 1 denotes handrails provided on both sides of the escalator, on which rubber handrails run in synchronization with the steps 5.

In view of the above-mentioned points, an object of the present invention is to provide an escalator that also serves to prevent oil leakage, such as oil flowing back due to capillary action.

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 3 and 4, in which the same parts as in FIG.
a, and a bent portion 21Ab bent downward at one end in the longitudinal direction (lower side in the inclined mounting state).

Also, oil pan 21B is connected to this oil pan 21A.
U, the bent portion 21Ab of the oil pan 21A has an appropriate wrap margin (indicated by A in FIG. 3) as in the conventional case.
It is installed with a step equal to the length of .

The rising portions 21Ba on both sides are formed so as to provide an appropriate gap (indicated by G in FIG. 4) with the rising portion 21Aa of the oil pan 21A, and the rising portions 21Ba on the other side in the longitudinal direction (lower side in the inclined mounting state) The end portion forms a bent portion (not shown) that is bent downward in the same manner as the end portion of the oil pan 21A described above.

Since the present invention is constructed as described above, the oil pan on the lower side of the slope has a step and is arranged in a ramp manner, so that the oil flows like X and oozes out onto the exterior plate 9. It does not look bad or stain the user's clothes.

In the above embodiment, a downwardly bent portion is formed to provide a step, but a spacer having an appropriate thickness may be used instead.
