Abstract

PROBLEM TO BE SOLVED: To expose a plus groove by only removing a cap when a comb is replaced, so that tightening release of a plus countersunk screw can be facilitated. SOLUTION: In this device, a cap 4 comprising a roof part 4a with a plane shape almost similar to a head part 3a of a plus countersunk screw 3 and a protrusion part 4b protruded in a downward direction from this roof part 4a to be fitted to a plus groove 3b of the plus countersunk screw 3, is mounted able to be mounted/demounted in a position covering the plus countersunk screw 3 closed. In this way, fine particular matter of sand, mud, etc., is prevented from infiltrating in the plus groove 3b, and the cap is only removed in the case of replacing a comb, so that the plus groove 3b can be easily exposed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a comb mounting device for an escalator used at a mounting portion of a comb installed at an escalator entrance.

[0002]

2. Description of the Related Art In general, a comb plate is provided at an entrance of an escalator, and a plurality of combs are detachably arranged side by side at the tip of the comb plate using a Phillips flat head screw (mounting screw). I have. These combs are molded products made of a hard synthetic resin material, and the teeth formed at their tips are engaged with the cleats of the steps. There is a need to.

[0003]

By the way, the head of a Phillips flat head screw that attaches the comb of the escalator to the comb plate,
Because of being exposed on the surface of the comb, fine particles such as sand, mud, and cotton dust adhering to the passenger's shoes and the like easily enter the plus groove formed in the head. When such fine particles enter the Phillips slot of the Phillips flat head screw, the Phillips slot becomes clogged. When exchanging a worn comb, insert the tip of a Phillips screwdriver into the Phillips slot. In many cases, it is difficult to release the fastening of the Phillips flat head screw as it is. Therefore, when removing such a Phillips countersunk screw, first, it is necessary to perform a complicated operation of scraping the fine particles packed in the Phillips groove so that the tip of the Phillips screwdriver can be correctly inserted into the Phillips groove. However, this has been a factor that prolongs the time required for comb replacement.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a comb mounting device for an escalator in which comb replacement work can always be efficiently performed.

[0005]

In order to achieve the above-mentioned object, the present invention relates to a comb mounting device for an escalator in which a comb is mounted at the tip of a comb plate provided at an entrance / exit.
A flat head screw for fixing the comb to the comb plate, and a cap which is detachably mounted at a position for closing the flat head screw with the lid closed, and the cap is flush with the head of the flat head screw. A top plate having substantially the same shape and a projection protruding downward from the top plate and fitted into the plus groove of the plus flat screw are used.

When the cap having such a structure is used, the head of the Phillips flat head screw as the mounting screw is not exposed on the surface of the comb. When the comb is replaced, the plus groove of the flathead screw can be exposed simply by removing the cap, so that the fastening of the flathead screw can be easily released with a Phillips screwdriver. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a comb mounting device according to the present invention will be described below with reference to FIGS. However, FIG. 1 is an exploded perspective view showing a head and a cap of a Phillips flat head screw according to this embodiment, FIG. 2 is a cross-sectional view showing a mounting structure of a comb in the embodiment, and FIG. FIG. 4 is a plan view of the comb when it is folded.

As shown in FIGS. 2 and 3, a plurality of combs 2 are provided at the tip 1a of the comb plate 1 provided at the entrance of the escalator.
Are provided side by side using a Phillips countersunk screw 3 so as to be detachable. These combs 2 are molded products made of a hard synthetic resin material, and a large number of teeth 2a formed at the tips thereof are engaged with step cleats (not shown).

A cap 4 made of an accessible synthetic resin material is removably mounted at a position on the surface of the comb 2 where each of the Phillips flat head screws 3 is closed. This cap 4 is a disposable part shaped like a tack (see FIG. 1).
And a disk-shaped top plate portion 4a having a plane shape substantially the same as that of the head portion 3a of the Phillips flat head screw 3, and fitted downward into the plus groove 3b of the Phillips flat head screw 3 so as to project downward from the top plate portion 4a. The cross section of the projection 4b has a cross shape corresponding to the plus groove 3b. Further, dimensions are set so that the surface of the top plate 4a does not have a step with respect to the surface of the comb 2 in a state where the cap 4 is mounted, that is, in a state where the protrusion 4b is fitted in the plus groove 3b. (See FIG. 2). Further, the cap 4 is colored so as to exhibit almost the same color (for example, yellow) as the comb 2.

The cap 4 may be formed by punching out a mold. However, if it is required that the cap 4 be a disposable and inexpensive part and yet obtain a desired shape, the cordless adhesive can be used. An adhesive stick (solidified ethylene vinyl chloride and acetate acetate resin in a rod shape) may be formed into a solution by, for example, the heat of an adhesive glue gun and poured into the head 3a of the Phillips flat head screw 3. . In that case, the head 3 including the inside of the plus groove 3b
If machine oil is previously attached to the surface of
This is preferable because there is no fear of adhering to the Phillips flat head screw 3 (head 3a).

If the cap 4 as described above is attached to the head 3a of the Phillips flat head screw 3 which is the mounting screw for the comb 2 of the escalator, the head 3a will not be exposed on the surface of the comb 2. There is no need to worry that fine particles such as sand, mud, and cotton dust enter the plus groove 3b of the plus countersunk screw 3 and cause clogging. Further, in the present embodiment, since the cap 4 is colored in the same color as the comb 2, even if the cap 4 is exposed in a part of the comb 2, it is inconspicuous. The design is better than in the case where the head 3a must be exposed. Moreover, in the present embodiment, the top surface of the cap 4 (the surface of the top plate portion 4a) is set so as not to generate a step with respect to the surface of the comb 2, so that the cap shoes 4 of the passenger are caught and the cap 4 comes off. It is difficult for accidents to occur.

When replacing the comb 2 worn for a long time with a new one, the head 3a of the
By removing the cap 4 that closes the cover, the plus groove 3b into which fine particles do not enter can be exposed as shown in FIG. 3, and a plus screwdriver (not shown) is inserted into the plus groove 3b. Thus, the operator can easily release the fastening of the flat head flathead screw 3. Therefore, a plurality of combs 2 arranged in parallel at the tip 1a of the comb plate 1
The time required for the replacement work can be greatly reduced as compared with the related art.

In this embodiment, since the cap 4 made of a contactable synthetic resin material is used, there is no fear that the cap 4 is broken and scattered when the comb 2 is replaced.

[0014]

The present invention is embodied in the form described above, and has the following effects.

A cap is fitted to the Phillips countersunk screw that attaches the comb of the escalator to the comb plate, and the head of the countersunk screw is closed with this cap. Since fine particles such as no longer enter the plus groove, the plus groove can be exposed simply by removing the cap when replacing the comb, so that the fastening of the flat head flat screw can be easily released, and thus the replacement work of the comb Time required can be greatly reduced.

Further, if the cap is made the same color as the comb, the cap becomes inconspicuous, so that the design becomes better as compared with the conventional structure in which the head of the flat head screw is exposed. In addition, if the surface of the top plate of the attached cap is set so as not to have a step with respect to the surface of the comb, it is possible to prevent the falling off accident that the cap etc. of the passenger is caught and the cap comes off. Can be.
