The conventional comb for escalator is configured as shown in FIGS. 5 to 7, and the comb tooth 3a at the tip of the comb 3 has the cleat groove 2a on the step 2.
By engaging with, the foreign matter is prevented from falling and being caught in the gap between the front end of the floor plate 1 and the step 2.

Further, passengers of the escalator are particularly concerned with the steps 2
When getting off, the approach of the comb 3 accompanying the progress of the escalator is sensed in advance, and the comb 3 is straddled between the step 2 and the floor board 1 at the entrance / exit. However, if the passenger on the step 2 does not notice the approach of the comb 3, the toes may collide with the comb teeth 3a, which may lead to loss of body balance and impair the riding comfort.

[0005]

As described above, the conventional escalator combs do not take measures against collision with the foot of the passenger, so that the ride comfort should be improved when the passenger does not notice the approaching entrance / exit. There was a problem that it might be damaged.

The present invention has been made to solve the above problems, and an object thereof is to obtain an escalator comb that does not impair the riding comfort even when the passengers of the escalator do not notice the approach of the entrance / exit. And

[0007]

A comb for an escalator according to claim 1 of the present invention is provided with a comb tooth arranged at an entrance / exit so as to engage with a cleat groove of a moving step, and a part of a rotating surface. Is provided with a roller that protrudes from the upper surface of the comb and is rotatable in a direction coinciding with the traveling direction of the step, and a latch that prevents reverse rotation of the roller.

According to a second aspect of the present invention, in the escalator comb according to the first aspect, a concavo-convex portion that engages with the tip of the latch is provided on the outer peripheral surface of the roller.

[0009]

According to the first aspect of the present invention, when the passenger on the step does not notice the approach of the entrance / exit and the foot of the passenger climbs up on the comb, the roller rotates to smoothly move on the floor plate of the entrance / exit. Move to.

Further, according to a second aspect of the present invention, the reverse rotation prevention mechanism is constituted by preventing the unnecessary slippage by the uneven portion on the outer peripheral surface of the roller and engaging the uneven portion with the latch.

【Example】

Example 1. Embodiment 1 of the present invention will be described below with reference to the drawings. 1 is a perspective view showing a first embodiment of the present invention, FIG. 2 is a plan view showing the first embodiment of the present invention, and FIG. 3 is an A- line in FIG.
FIG. 4 is a cross-sectional view taken along the line A, and FIG. 4 is an enlarged cross-sectional view showing the inside of the one-dot chain line B in FIG. 3. In each drawing, 2, 2a, 3 and 3a are the same as those described above. The entire escalator device is as shown in FIG.

Reference numeral 4 is a roller pivotally attached to the tip of the comb 3, and is arranged so that a part of the rotation surface thereof projects from the upper surface of the comb 3. The arrow E indicates the traveling direction of the step 2, and the arrow F indicates the rotatable direction of the roller 4.

Further, in FIG. 4, reference numeral 4a denotes a rotary shaft of the roller 4, and 4b denotes an uneven portion provided on the outer peripheral surface of the roller 4,
Reference numeral 5 denotes a bearing for pivotally mounting and positioning the rotary shaft 4a of the roller 4, 6 is a support portion for fixing the bearing 5, 7 is a bolt for integrally fixing the support portion 6 to the back surface of the comb 3, and 8 is an uneven portion 4b. It is a latch that is engaged to form a reverse rotation preventing mechanism for the roller 4. In this case, the concavo-convex portion 4b of the roller 4 has a slip preventing function and also functions as a hanging allowance for preventing reverse rotation.

Next, the operation of the first embodiment of the present invention shown in FIGS. 1 to 4 will be described with reference to FIG. Now, suppose that the passenger on the step 2 does not notice the approach of the comb 3 due to carelessness, and the foot of the passenger collides with the tip of the comb 3. At this time, the toes of the passenger ride on the rotation surface of the roller 4 protruding from the upper surface of the comb 3 according to the moving speed of the step 2, and are smoothly guided and move on the comb 3. Therefore, the passenger's riding comfort is not impaired due to loss of body balance, and the passenger can move onto the floor plate 1 at the entrance / exit.

Further, since the concavo-convex portion 4b is engaged with the latch 8, even if a force in the direction opposite to the rotational direction F is applied to the roller 4, the tip of the latch 8 is caught by the concavo-convex portion 4b. Therefore, it does not rotate in the reverse direction. Therefore, the roller 4
Can rotate only in the direction F coinciding with the traveling direction E and does not reversely rotate in an unnecessary direction. Therefore, the passenger's foot trying to walk at the entrance / exit does not slip, and It does not compromise safety.

Further, since there is an appropriate rotational load between the uneven portion 4b and the latch 8, the roller 4 does not unnecessarily rotate excessively, and passengers who get off the step 2 to the required entrance / exit are prevented. I can't get my feet off.

Example 2. Although the roller 4 is integrally formed in the first embodiment, it may be divided into a plurality of parts along the direction of the rotating shaft 4a. Further, although the uneven portion 4b is provided on the outer peripheral surface of the roller 4 and engaged with the latch 8, if the roller 4 is made of a material that is not slippery, it is not necessary to provide the uneven portion 4b. In this case, a reverse rotation preventing mechanism that engages with the latch 8 may be provided on the rotating shaft 4a, for example.

[0018]

As described above, according to the first aspect of the present invention, the comb teeth are provided at the entrance / exit so as to engage with the cleat groove of the moving step, and a part of the rotating surface has the comb teeth. A roller that protrudes on the upper surface and is rotatable in a direction coinciding with the direction of travel of the step, and a latch that prevents reverse rotation of the roller are provided, and when the foot of a passenger on the step rides on the comb at the entrance / exit, the roller Since the vehicle is smoothly moved onto the floor plate of the entrance / exit by rotating, it is possible to obtain the comb for the escalator that does not impair the riding comfort even when the passenger does not notice the approach of the entrance / exit.

According to a second aspect of the present invention, in the first aspect, an uneven portion which engages with the tip portion of the latch is provided on the outer peripheral surface of the roller to form a reverse rotation preventing mechanism and prevent unnecessary slippage. Therefore, even if the passenger of the escalator does not notice the approach of the entrance / exit, the comb for the escalator that does not impair the riding comfort can be obtained with a simple configuration.
